                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and consolidated financial statements, including the notes thereto,
appearing elsewhere in this Prospectus. As used in this Prospectus, the terms
the "Company" and "Neogen" refer to Neogen Corporation and its wholly-owned
subsidiaries unless the context otherwise requires. Unless otherwise indicated,
information in this Prospectus assumes that the Underwriters' over-allotment
option is not exercised. The Company's fiscal year ends on May 31.
 
                                  THE COMPANY
 
     Neogen Corporation develops, manufactures, and markets a diverse line of
products used to detect residues and improve quality for the agriculture, food,
pharmacologics and environmental industries. 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, disease infections and quality aspects. These
diagnostic test kits are 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 market for diagnostic products for food and environmental safety has
been estimated to be approximately $500 million by the year 2000. The Company
estimates that currently only 12% of the food safety and environmental testing
is done by diagnostic test kits such as those manufactured by the Company.
Approximately 88% of the total potential market is either not testing or is
still using older, traditional methods that are generally slower, more difficult
to use and more expensive. In July 1996, the U.S. Department of Agriculture's
Food Safety Inspection Service adopted a final rule governing (i) federally
inspected meat and poultry processing plants and (ii) businesses outside the
U.S. which export meat and poultry into the U.S. In December 1995, the U.S. Food
and Drug Administration issued a final rule, scheduled to become effective
January 1998, concerning the procedures required for the safe and sanitary
processing and importing of fish and fishery products. As a result of increased
public concern over food quality and the aforementioned governmental regulations
concerning food inspection, a significant portion of this untapped market
represents testing that is not being conducted today and testing that will occur
over the next few years.
 
     The Company has developed and markets over 140 diagnostic test kits used in
food safety, plant diseases, animal health, 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 Company's Ideal Instruments subsidiary manufactures and
markets over 250 different veterinary instrument products used in obstetrics and
surgery and to administer animal health.
 
     The Company's marketing strategy has been to expand its product offerings
through multiple market segments. The Company has focused on selling its
products into seven market segments: grain, nut and spice processors; meat,
poultry and egg processors; seafood processors; animal producers; fruit and
vegetable producer/processors; human clinical and pharmacologic research; and
private and public laboratories. This strategy has allowed the Company to become
the market leader in diagnostic products for the grain, nut and spice processor
industry and to become the dominant producer of diagnostic tests for the
detection of drugs in animals. Further, the Company has devoted significant
resources to take advantage of recent changes in testing requirements for the
meat, poultry and egg processor and seafood processor industries.
 
     The Company's vision is to become a world leader in diagnostic development
and marketing. The Company has developed a growth strategy to achieve this
vision 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 businesses and forming strategic
alliances.

                                  RISK FACTORS
 
     Prospective investors should carefully consider the factors set forth
below, as well as other information included elsewhere herein or incorporated by
reference, prior to purchasing the shares of Common Stock offered hereby:
 
IDENTIFICATION AND INTEGRATION OF ACQUISITIONS
 
     The Company's business has grown significantly over the past several years
as a result of both internal growth and acquisitions of products and businesses.
The Company plans to use a portion of the proceeds of this offering to make
additional acquisitions. See "Use of Proceeds." The Company has no agreements or
commitments in place with respect to, and is not currently engaged in any
negotiations for, any acquisition. Identifying and pursuing acquisition
opportunities, integrating these acquisitions into the Company's business, and
managing their growth require a significant amount of management time and skill.
There can be no assurance that the Company will be effective in identifying,
integrating or managing any acquisition target in the future. The failure to
successfully integrate and manage any future acquisition may have a material
adverse effect on the Company's operating results and financial condition.
 
NEW PRODUCT DEVELOPMENT RISKS
 
     The Company is continually developing new products for which it believes
there should be significant market demand. There can be no assurance that the
Company will successfully develop these products, that the products will be
developed on a timely basis to meet market demand, or that the relevant market
will be properly identified. If the Company expends substantial resources in
developing an unsuccessful product, operating results will be adversely
affected.
 
INTERNATIONAL SALES
 
     In fiscal 1996, international sales accounted for 21% of the Company's
total revenue. The Company expects that its international business will continue
to account for a significant portion of its total revenue. Foreign regulatory
bodies may establish product standards different from those in the U.S. and with
which the Company's current products do not comply. The inability of the Company
to design products to comply with foreign standards could have a material
adverse effect on the Company's future growth. Other risks related to
international sales include the possible disruption in transportation,
difficulties in building and managing foreign distribution, fluctuation in the
value of foreign currencies, import duties and quotas, and unexpected economic
and political changes in foreign markets. There can be no assurance that these
factors will not adversely affect international sales and the Company's overall
financial performance.
 
COMPETITION
 
     The markets in which the Company competes are subject to rapid and
substantial changes in technology. The Company encounters, and expects to
continue to encounter, competition in the sale of its products. There can be no
assurance that new technology or products developed by the Company's competition
will not render the Company's products or technologies obsolete or
noncompetitive. Many of the Company's competitors and potential competitors have
greater capital, manufacturing, marketing, and research resources than the
Company. See "Business -- Competition."
 
DEPENDENCE ON AGRICULTURAL MARKETS
 
     The Company's primary markets relate to agricultural and food production.
The agricultural marketplace is cyclical and is dependent upon many factors
outside the Company's control including weather conditions. A downturn in the
agriculture marketplace could adversely affect the Company's sales.
 
FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
     The Company has experienced, and may experience in the future, significant
fluctuations in its quarterly operating results. Factors such as the mix of
products sold, and the acceptance of new products, could contribute to this
quarterly variability. The Company operates with relatively little backlog and
has few
 
                                        5
<PAGE>   8
 
long-term customer contracts. Substantially all of its product revenue in each
quarter results from orders received in that quarter. In addition, the Company's
expense levels are based, in part, on expectation of future revenue levels. A
shortfall in expected revenue could, therefore, result in a disproportionate
decrease in net income.
 
PATENTS, TRADE SECRETS AND LICENSES
 
     The Company relies on a combination of patent, trade secret and trademark
law to protect its proprietary rights. There can be no assurance that patent
applications filed by the Company will result in the issuance of patents. There
can also be no assurance that the Company's nondisclosure agreements, together
with trade secrets and other common law rights, will provide meaningful
protection for the Company's trade secrets and other proprietary information. In
the absence of these assurances, the Company's business may be adversely
affected by competitors. From time to time, the Company has received notices
alleging that the Company's products infringe third party proprietary rights,
though no material legal action in this regard is currently pending. If the
Company is precluded from selling its products or is required to pay damages
with respect to such sales, the Company's business and results of operation
could be adversely affected. See "Business -- Proprietary Protection and
Approvals."
 
REGULATION BY GOVERNMENT AGENCIES
 
     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. Though
less than 10% of the Company's revenues is currently derived from products
requiring government approval prior to sale, a significant portion of its
revenues 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. If, for some reason, these rules are overturned or
significantly modified, there would be a significant adverse affect on the
Company's future growth strategies. See "Business -- Governmental Regulation."
 
DEPENDENCE ON KEY EMPLOYEES
 
     The Company's success depends, in large part, on its president and on other
members of its management team. The loss of services of these key employees
could have a material adverse effect on the Company. The Company maintains
certain incentive plans for its key employees and most of these employees have
been with the Company in excess of three years. However, the Company has not
executed long-term employment agreements with any of these employees and does
not expect to do so in the foreseeable future. The Company's success also
depends, significantly, on its ability to continue to attract such personnel.
There can be no assurance that the Company will be able to retain or attract
such personnel.
 
PRODUCT LIABILITY AND INSURANCE
 
     The manufacturing and distribution of the Company's products involve an
inherent risk of product liability claims and the adverse publicity that may be
associated with such claims. Although the Company currently maintains liability
insurance, there can be no assurance the Company will be able to continue to
obtain such insurance on acceptable terms, or that such insurance will provide
adequate coverage against all potential claims. See "Business -- Insurance."
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
     The market prices for securities of technology companies have been volatile
in the past and could continue to be volatile in the future. Fluctuations in
financial performance from period to period may occur and could have a
significant impact on the market price of the Company's stock.

                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the 1,500,000 shares of
Common Stock offered hereby are estimated to be $          ($          if the
Underwriters' over-allotment option is exercised in full), after deducting the
underwriting discounts and commissions and estimated offering expenses.
 
     The Company intends to use the net proceeds primarily for general corporate
purposes, including potential acquisitions of businesses or products, licenses
of technologies and working capital needs. The Company expects to devote a
portion of the net proceeds to fund such acquisitions or licenses. The Company
expects that it may effect acquisitions to expand its product and service
offerings within its current markets, although the Company may also seek to
effect acquisitions to extend its business into complementary markets. While the
Company has made such acquisitions in the past, the Company has no agreements or
commitments with respect to, and is not currently engaged in any negotiations
for, any acquisition. The amount of the net proceeds actually expended for
acquisitions, licenses or working capital purposes will depend upon a number of
factors, including the Company's ability to identify and effect attractive
acquisitions and licenses, and the amount of cash generated by the Company's
operations.
 
     Pending the uses described above, the net proceeds will be used to reduce
short-term bank borrowings and will be placed in short-term, interest bearing,
investment grade securities, certificates of deposit or direct or guaranteed
obligations of the United States of America.

                                DIVIDEND POLICY
 
     The Company has never paid any cash dividends on its Common Stock and does
not anticipate paying any cash dividends in the foreseeable future. The Company
currently intends to retain future earnings to fund the development and growth
of its business. Any future distributions will be made at the discretion of the
Board of Directors of the Company and will depend upon the Company's operating
results, financial condition, capital requirements, general business conditions
and such other factors as the Board of Directors deems relevant.

     The following table sets forth selected consolidated financial data of the
Company for each of the fiscal years ended 1992 through 1996 and for the three
months ended August 31, 1995 and 1996. The selected consolidated financial data
for the five fiscal years in the period ended May 31, 1992 through 1996 are
derived from the Company's audited Consolidated Financial Statements. The
selected consolidated financial data for the three months ended August 31, 1995
and 1996 are derived from the Company's unaudited quarterly financial
statements. In the opinion of management, the three month financial data reflect
all adjustments (consisting only of normal recurring adjustments) necessary for
a fair presentation of such data. The results for the first three months of
fiscal 1997 are not necessarily indicative of the results to be expected for the
full year. The information below should be read in conjunction with the

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with
the Company's Consolidated Financial Statements and the notes thereto appearing
elsewhere in this Prospectus.
 
RESULTS OF OPERATIONS
 
  Comparison of Three Months Ended August 31, 1996 and 1995
 
     Total revenues for the quarter ended August 31, 1996 were $1,109,000 or 38%
higher than the same quarter in 1995. Sales of diagnostic products were up
$1,213,500 in the first quarter representing an increase of 55% while sales of
veterinary instruments declined $31,000 or 5%. Contract revenues in the first
quarter decreased $73,500 or 94%.
 
     The significant increase in diagnostic product sales was primarily due to a
$684,000 or 120% increase in sales of the Company's diagnostic test kits for the
detection of vomitoxin. In early July 1996, a large portion of midwest winter
wheat was found to contain high levels of vomitoxin due to cool, rainy weather
conditions during the flowering stages of the grain. Although sales of vomitoxin
test kits should continue to run higher than the prior year for the remainder of
fiscal 1997, it is unlikely that sales will continue at the pace experienced in
the first quarter.
 
     The Company also experienced an increase in sales of $122,000 or 220% for
test systems to detect E. coli O157:H7 and salmonella. Approximately $37,000 of
this increase was due to international sales of E. coli test kits shipped to
Japan. The remaining increase is the result of a growing demand for test kits to
detect micro-organisms. Management believes that the July 1996 announcement of
new inspection and safety regulations for the meat and poultry industry
scheduled to begin implementation in January 1997, will have a positive effect
on future sales.
 
     The decline in veterinary instrument sales was due to depressed cattle
prices resulting in lower overall demand for durable veterinary instruments. In
management's opinion, the current down cycle in cattle prices should improve
over the remainder of this fiscal year. In addition, the Company has reorganized
its sales and marketing efforts for veterinary instruments which management
believes will favorably impact future sales for this segment.
 
     The decline in contract revenues for the first quarter of this year was
primarily due to scheduled completion in the second quarter of last year of two
contracts with the United States Department of Agriculture. It is common for
contract revenues to fluctuate from quarter to quarter and year to year
depending on timing and terms of the contracts.
 
     Cost of goods sold increased 31% as a direct result of the overall increase
in product sales. Expressed as a percentage of sales, cost of goods sold was 38%
in the first quarter of fiscal 1997 compared to 42% in the first quarter of
fiscal 1996. This improvement was due to a higher sales mix of diagnostic test
kits, increased labor productivity and better utilization of fixed overhead
costs for diagnostic products.
 
     Sales and marketing expenses increased $311,000 in the first quarter
compared to the prior year. Commissions and royalties expense increased $133,000
in the first quarter due to increased sales volume. Expenses for printing,
advertising and promotions related to sales activities for diagnostic products
increased $64,000 compared to the prior year. A total of $37,000 was due to
higher salaries, fringe benefits and travel costs associated with the hiring of
new salesmen and technical support personnel. The remaining increase is
primarily due to an increase in the provision for doubtful accounts.
 
     General and administrative expenses were $124,000 higher in the quarter
ended August 31, 1996 than the quarter ended August 31, 1995. Bonus accruals
increased $75,000 in the first quarter compared to last year based on improved
operating performance. Michigan Single Business Tax was $16,000 higher than the
prior
 
                                       10
<PAGE>   13
 
year due to increased profitability at the Company's Lansing, Michigan
operations. Salaries for clerical and accounting personnel increased $12,000 due
to higher sales volume. As a percentage of total revenues, general and
administrative expense declined to 14% in the first quarter compared to 15% last
year.
 
     Although research and development expense increased less than 10% in the
first quarter this year compared to the first quarter last year, management
believes that research and development is critical to the Company's future.
Accordingly, the Company expects its annual research and development expense for
the current fiscal year to approximate the same levels, expressed as a
percentage of revenue, as experienced in prior years.
 
     Other income (expense) was lower in the first quarter than last year
primarily due to the timing of recognition of the Company's share of royalties
paid to an affiliated partnership.
 
     Due to the substantial increase in sales volume for diagnostic products in
the first quarter, the Company posted net income of $.08 per share compared to
$.03 per share in the same period last year.
 
  Comparison of Fiscal Years Ended May 31, 1996 and 1995
 
     Total revenues for the year increased 7% due to a strong 20% increase in
sales of diagnostic products. Of the $1,429,000 increase in diagnostic product
sales, $608,000 was the result of a 15% increase in sales of test kits to detect
harmful mycotoxin residues in the feed, grain, and nut markets. Another $621,000
of the increase was due to 30% higher sales of test kits and reagents sold into
the pharmacologics and equine markets. The remainder of the increase was due to
a 164% increase in test kits to detect microorganisms in the meat and poultry
market.
 
     The increase in sales of diagnostic products was partially offset by a
decline in veterinary instruments sales. The decline in sales in this segment
was partially due to depressed cattle prices resulting in lower demand for
durable veterinary instruments. Sales representation that management believed
was unsatisfactory also contributed to the decline in sales causing the Company
to restructure its sales organization for veterinary instruments.
 
     Contract revenues decreased significantly in 1996 due to scheduled
completion of two contracts awarded to the Company in September 1994 by the
United States Department of Agriculture. It is common for contract revenues to
fluctuate from year to year depending on terms and timing of the contracts.
However, contract revenues in total are not significant to total revenues for
the Company.
 
     Expressed as a percentage of product sales, cost of goods sold was 44% in
1996 compared to 45% in 1995.
 
     The increase in sales and marketing expenses is principally due to higher
costs in two areas. Entry into the meat and poultry market resulted in
approximately $130,000 of increased expense spread across a number of categories
including salary, fringe, travel, printing, advertising, and trade shows.
Increases in cost for the same categories totaled $110,000 related to the
introduction of new products for the seafood and equine markets. Increases in
sales and marketing expenses for the feed, grain, and nut markets, primarily in
the areas of royalties, shipping expense, and special promotions, were almost
completely offset by lower commissions related to veterinary instruments sales.
The Company expects to continue to expand sales and marketing activities
primarily in areas related to diagnostic products for food safety.
 
     General and administrative expenses are higher as a result of several
items. A total of $55,000 of the increase is due to two extra months of
operations in 1996 than 1995 for AMPCOR Diagnostics, Inc. (ADI). Salary and
fringe expenses were up $150,000 as a result of new secretarial, accounting, and
clerical personnel needed to handle increased business volume. Amortization
expense was $40,000 higher than last year due exclusively to the acquisition of
certain assets of International Diagnostic Systems, Corp. (See Note 3 of the
Notes to Consolidated Financial Statements).
 
     The $102,000 increase in research and development cost is partially due to
$44,000 of added expense this year because of an extra two months of operations
at ADI compared to last year. The remainder of the increase is the result of
higher salaries, fringe, and supplies for research programs to develop new
diagnostic
 
                                       11
<PAGE>   14
 
test kits for the equine and pharmacologic markets and for the detection of
harmful bacteria. The Company considers investment in research activities
critical to the long-term future of the business.
 
     Restructuring charges recorded in the fourth quarter of 1996 pertain to
costs associated with discontinuance of the Company's electronic instrument
operations and reorganization of sales and marketing efforts for veterinary
instruments. (See Note 2 to Consolidated Financial Statements.) Liabilities
recorded at May 31, 1996 as a result of the restructuring program amounted to
$218,000 and are expected to be paid or settled during fiscal year 1997.
Management believes that the restructuring program places the Company in a
better competitive position to achieve future growth. The restructuring also
enables the Company to redirect manpower and financial resources to the more
profitable and faster-growing diagnostics business.
 
     Other income declined during 1996 primarily due to higher interest expense
as a result of increased balances outstanding for bank borrowings.
 
     The net loss for the year is primarily due to restructuring charges of
$695,000 recorded in the fourth quarter.
 
  Comparison of Fiscal Years Ended May 31, 1995 and 1994
 
     Diagnostic product sales increased $670,000 in 1995 compared to 1994. Sales
in this segment were up $797,000 due to the acquisition of AMPCOR Diagnostics,
Inc. (formerly AMPCOR, Inc.) effective August 1, 1994. In addition, sales for
the ELISA Technologies division consisting of pharmacological and animal drugs
of abuse diagnostic test kits increased $451,000 or 30% in 1995.
 
     The positive increase in sales for these two are as was partially offset by
a $593,000 reduction during 1995 in sales of diagnostic test kits for the
detection of vomitoxin. Management anticipated a decline in sales for vomitoxin
test kits in the current year as indicated in its 1994 annual report to
shareholders.
 
     The increase in veterinary instrument sales for 1995 compared to 1994 is
primarily due to a new customers who began ordering specialized needles and
punches in the first quarter of 1995.
 
     Contract revenues increased significantly in 1995 due to two contracts
awarded to the Company in September 1994 by the United States Department of
Agriculture. It is common for contract revenues to fluctuate from year to year
depending on terms and timing of the contracts. However, contract revenues in
total are not significant to total revenues for the Company.
 
     The increase in cost of goods sold for 1995 is the direct result of higher
sales volume, including acquisitions, compared to 1994.
 
     Sales and marketing expenses increased $449,000 or 16% in 1995 compared to
1994. Of this amount, $217,000 was due to a new marketing agreement with an
independent third party firm for the veterinary instrument product line. Another
$146,000 of the increase was the direct result of the acquisition of AMPCOR. The
remaining difference is due to increases in salaries and wages, advertising,
royalties and distribution costs pertaining to increased sales volume, and new
marketing programs for products sold by the ELISA Technologies division. The
Company intends to expand its sales and marketing activities for predictive and
diagnostic products primarily in the meat and poultry and seafood markets.
 
     The increase in general and administrative expenses is due to $223,000 of
costs generated by the operations of AMPCOR which was acquired effective August
1, 1994. This increase was partially offset by lower general and administrative
expenses at the Company's Lansing, Michigan-based operations due to lower
bonuses for employees in 1995 compared to 1994 and a reduction in legal and
professional fees.
 
     Research and development expenses were up $280,000 or 33% in 1995 compared
to 1994. A total of $185,000 was the result of research projects being conducted
at AMPCOR. The remaining difference is primarily due to higher salaries and
wages, contract services, and supplies related to several research projects for
new diagnostic products. Three of these projects are being funded via contracts
with the United States Department of Agriculture. The Company intends to
continue to expand its research activities for new predictive and diagnostic
products.

     Other income (expense) is $113,000 higher in 1995 than in 1994. In 1994,
the Company recorded a one-time $75,000 write-down to an investment in an
affiliated partnership to reflect current market value. Interest income is
$26,000 higher in 1995 due primarily to higher rates on invested funds. The
Company also recorded $72,000 in 1995 as its share of earned royalties paid to
an affiliated partnership. The positive effect of these items was partially
offset by $66,000 of higher interest expense in 1995 due to increased borrowings
and higher rates.
 
     Net income for the year ended May 31, 1995 declined by $177,000 compared to
1994 due primarily to increases in research and development expenditures.
 
FINANCIAL CONDITION AND LIQUIDITY
 
     At August 31, 1996, the Company had $2,389,000 in cash and equivalents,
working capital of $5,659,000 and stockholders' equity of $9,355,000. In
addition, the Company has bank lines of credit totaling $2,500,000, with
$1,029,000 borrowed against these lines as of August 31, 1996.
 
     Effective June 15, 1995, the Company acquired certain assets of
International Diagnostic Systems Corporation (IDS) of St. Joseph, Michigan (See
Note 3 of the Notes to Consolidated Financial Statements.) The purchase price
paid in fiscal year 1996 was approximately $680,000 in cash. A second and final
cash payment of approximately $53,000 was paid in July 1996.
 
     On August 17, 1994, the Company purchased substantially all of the assets
of AMPCOR, Incorporated, a New Jersey-based diagnostics company. The total
initial purchase price paid was approximately $1,871,000 consisting of $813,000
in cash (including acquisition costs), assumption of liabilities totaling
$733,000, and issuance of 55,763 shares of the Company restricted common stock
valued at $325,000. In connection with the acquisition, the Company entered into
a $400,000 term loan agreement and $600,000 line of credit facility,
subsequently increased to $1,000,000, with Comerica Bank (See Note 3 of the
Notes to the Consolidated Financial Statements). Proceeds from the term loan,
together with $256,000 borrowed against this line of credit, were used to pay
off certain liabilities assumed in the purchase of AMPCOR, Incorporated's
assets.
 
     The Company has no material commitments for capital expenditures at August
31, 1996. Inflation and changing prices are not expected to have a material
effect on the Company's operations.
 
     Prior to its 1994 fiscal year, cash required to sustain operations, retire
long-term debt, pay for capital expenditures, and fund acquisitions had been
primarily generated by proceeds from stock offerings. However, the Company was
profitable and did experience positive cash flows from operations in fiscal year
1994, was profitable again in 1995, and generated positive cash flows from
operations again in fiscal year 1996. Management believes this shows significant
progress toward achieving consistently positive cash flows from operations on an
annual basis. Management also believes that the Company's existing cash and cash
equivalents at August 31, 1996, along with its available bank lines of credit,
and the proceeds of this offering will be sufficient to fund normal operations
for the foreseeable future. Such funds may not be sufficient to meet the
Company's longer term 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.

                                    BUSINESS
 
GENERAL
 
     Neogen Corporation develops, manufactures, and markets a diverse line of
products used to detect residues and improve quality for the agriculture, food,
pharmacologics and environmental industries. 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, disease infections and quality aspects. These
diagnostic test kits are 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, plant diseases, animal health, 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 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 vision is to become a world leader in diagnostic development
and marketing. 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
 
  First Quarter Results
 
     The Company's revenues in its first quarter ended August 31, 1996 were 38%
greater than its revenues for the same quarter in the previous year. These sales
were led by an increase in the Company's diagnostic test kits for the detection
of vomitoxin in wheat, due to a major outbreak of this fungal-related, natural
toxin in the central and upper midwest states of Ohio, Indiana, Michigan,
Wisconsin, North and South Dakota and Minnesota. This toxin is not regulated as
a human pathogen, but its presence affects the quality of flour and feed
intended for animal use.
 
  Japanese E. Coli Outbreak
 
     The severe outbreak of infections from the bacteria E. coli O157:H7 in
Japan in July 1996 also had an impact on the Company's diagnostic sales. Company
management believes these sales opportunities will continue to grow as the
Japanese government now considers mandating E. coli O157:H7 testing in all of
its meat processing plants.
 
  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,
and management believes this impact will be even greater in the future. 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 will require mandatory testing for a
number of hazardous adulterants that may affect the safety of meat and poultry.
Though these
 
                                       14
<PAGE>   17
 
regulations do not begin to become effective until January 1997, management
expects them to have a positive impact on sales of several of the Company's
diagnostic test kits, such as the one to detect salmonella.
 
  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 does 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.
 
  Salmonella Test Approved
 
     In September 1996, the Company was awarded an approval and certification
for its diagnostic test kit for the detection of salmonella by the Association
of Official Analytical Chemists -- Research Institute. This is a third party
test validation organization which is recognized on a worldwide basis.
Management believes this certification will further enhance sales of this
disposable diagnostic test kit.
 
  New Distributorship Signed
 
     In September 1996, the Company entered into a distribution agreement with
Merck KGaA to become the exclusive distributor to the U.S. food processing
industry for that company's test to determine the level of plant sanitation.
Marketed under the trade name Hy-Lite(R), the test detects the presence of any
living cells as an indication of whether processing equipment and other surfaces
have been properly cleaned and sanitized. The test requires less than 10 minutes
to conduct and is portable enough to be used at the site where cleaning is
taking place.
 
  Restructuring Program Announced
 
     In June 1996, the Company announced a restructuring program for certain
operating divisions. As part of the restructuring plan, the Company discontinued
its electronic instrument operations and implemented a reorganization of sales
and marketing activities related to veterinary instruments. The restructuring
program was designed to better position the Company over the long term to
compete more efficiently and increase market share. In connection with the
restructuring plan, the Company incurred a one-time charge of $696,000, or $.15
per share, in the fourth quarter of fiscal 1996. See Note 2 of the Notes to
Consolidated Financial Statements.
 
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 acquisitions completed in the
past three years.
 
  International Diagnostic Systems Corporation
 
     In June 1995, the Company acquired certain assets of International
Diagnostic Systems Corporation of St. Joseph, Michigan. The Company acquired
inventory and technology for 35 different diagnostic tests used to detect drugs
of abuse in animals. The business was moved to the Company's ELISA Technologies
division in Lexington, Kentucky.
 
  AMPCOR, Incorporated
 
     In August 1994, the Company, through its wholly owned subsidiary, AMPCOR
Diagnostics, Inc., acquired substantially all of the assets of AMPCOR,
Incorporated of Camden, New Jersey. The Company relocated the business to larger
facilities in Bridgeport, New Jersey and maintained most of the former company's
products and employees. The products and technologies allowed the Company to
make a strong entry into the market for the rapid detection of foodborne
bacteria.
 
                                       15
<PAGE>   18
 
  Enzytec, Incorporated
 
     In October 1993, the Company acquired substantially all the assets of
Enzytec, Incorporated of Kansas City, Missouri. All acquired assets, consisting
of inventory, patent licenses and furniture and fixtures, were moved to the
Company's Lansing, Michigan operations and integrated with existing
manufacturing and marketing efforts. This acquisition provided the Company with
products and technology necessary to detect pesticides in food and in the
environment.
 
BUSINESS STRATEGY
 
     The Company's vision is to become a worldwide leader in offering diagnostic
and detection products to the food, environmental and related markets. The
Company expects to expand its diagnostics and detection 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. The Company
     focuses on selling its products into seven market segments: grain, nut and
     spice processors; meat, poultry and egg processors; seafood processors;
     animal producers; fruit and vegetable producers/processors; 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. This strategy has allowed the
     Company to become the market leader in diagnostic products for the grain,
     nut and spice processing industry and in diagnostic tests for the detection
     of drugs in animals. Further, the Company has devoted significant resources
     to take advantage of recent changes in testing requirements for the meat,
     poultry and egg, and seafood processor markets.
 
          - Introduction Of New Products. The Company has a continued commitment
     to research and development programs and has invested approximately 10% 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, which offers the opportunity to generate repeat
     sales. In fiscal 1996, approximately 70% of the Company's total revenue was
     generated from sales of these disposable products. Further, the Company's
     strategy is to develop new products that generally utilize the Company's
     existing, proven technology base that is already well accepted by existing
     customers.
 
          - 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. In fiscal 1996,
     21% of the Company's total revenue was derived from international sales. A
     majority of these sales came from South and Central America where the
     Company has an established distribution system. While the Company expects
     its business in the South and Central American markets to continue to grow,
     it plans to devote additional resources to the Asian and European markets
     as a new source of international sales. 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 demonstrated through its license with the U.S.
     Department of Agriculture for specific antibodies and a recently completed
     distribution agreement with Merck KGaA for U.S. distribution of its test
     kit for the detection of proper sanitation. 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
 
     Detection and diagnostic tests are used in a broad range of applications,
including food safety, environmental safety, plant health and animal health. In
the plant-related food area, tests are used to detect the presence of harmful
plant diseases, pesticide residues, naturally-occurring toxins, foodborne
bacteria and numerous general areas of quality such as fats, proteins and
vitamins. In the area of animal and seafood-related food products, detection and
diagnostic tests are used to detect the presence of diseases, harmful
contaminants in animal feeds, foodborne bacteria, natural toxins, drug residues
and a number of aspects of quality including proper cooking and protein
composition.
 
     Industry consulting groups have estimated the total market for testing of
food and environmental safety will be in the range of $500 million by the year
2000. 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. These tests
allow the food and agricultural industries to conduct tests on-site with less
skilled technicians and a considerably reduced investment in laboratory
equipment. More importantly, the rapid test systems can provide results in hours
rather than days and reduce the likelihood of unsafe food reaching the food
distribution systems.
 
COMPANY MARKETS
 
     The Company has focused its strategy on the food safety market with its
diagnostic products. 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 the
following seven definable market segments:
 
     Grain, nut and spice processors. These commodities generally serve as the
foundation of the food chain. Therefore, it is important to determine their
quality on a daily basis. Over 1.8 billion tons of grain are harvested and
stored each year throughout the world. 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 almost universally consumed. The safety of
these ingredients is a significant source of concern for snack food producers,
pasta manufacturers, flour millers, 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 world's
production of pork, chicken, turkey, eggs and a major portion of the beef supply
also depends on quality grains.
 
     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.
 
     Residues of a number of these adulterants are controlled by regulatory
agencies such as the U.S. Department of Agriculture and the U.S. Food and Drug
Administration. The Company has an exclusive supply agreement with the Federal
Grain Inspection Service to supply aflatoxin test kits that are used to screen
for the presence of this natural toxin for most grain crops that are shipped
from the U.S. The Company's test kit for vomitoxin, another of the naturally
occurring toxins, is also widely used by regulatory agencies.
 
     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. People all over the world have become
increasingly aware of the dangers foodborne bacteria can cause in meat and
poultry products. These pathogens cause illness in over 6.5 million people,
resulting in over 9,000 deaths in the U.S. annually, according to the Centers
for Disease Control and Prevention.
 
                                       17
<PAGE>   20
 
     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. Meat
often moves through several processing operations before reaching the consumer.
In addition to the carcass conversion plants, meat is typically handled again in
further processing and by food service and retail establishments. Foodborne
bacteria can be introduced at any one of these processing operations.
 
     Management believes that the meat and poultry group has the best
opportunity currently to contribute to the Company's growth. The Company offers
tests for the bacteria E. coli O157:H7, salmonella, and a test to determine the
general level of plant sanitation. Company scientists are developing additional
tests for the meat and poultry markets and expect to have two new foodborne
bacteria tests available before the end of the 1997 fiscal year. Some of the
Company's tests that were originally developed to detect drugs of abuse in
racing animals are also being used to detect the presence of these same drugs in
meat.
 
     A major reorganization in testing procedures by the U.S. Department of
Agriculture's Food Safety Inspection Service was announced in July 1996.
Beginning in January 1997 these new regulations will begin to become mandatory
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. The U.S. seafood industry records sales in excess of
$29 billion each year. Seafood is known to cause foodborne illnesses as a result
of both natural toxins and bacteria. At present, the U.S. seafood industry does
not have mandatory inspection requirements before its products can be marketed.
However, in December 1995, the U. S. Food and Drug Administration issued final
rules that will establish mandatory inspection programs for this industry in the
U.S. Though the final rules will not be in full force until January 1998, the
industry is now beginning to implement quality control procedures that will
include the use of rapid diagnostic tests similar to those manufactured by the
Company. The tests include a general sanitation rapid test to help seafood
processors ensure that processing equipment is adequately cleaned on a daily
basis to prevent product contamination. Other tests are used to detect the
presence of salmonella and histamine, natural toxins that 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.
 
     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. A number of these products have been 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.
Because the instruments are better engineered, they also minimize mechanical
injuries to muscle tissue which reduces the chance for infection.
 
     The Company also markets a vaccine and a line of topical 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. The value of fruit and vegetable
production in the U.S. alone is estimated at $15 billion annually. 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
 
                                       18
<PAGE>   21
 
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. As an example, the Company markets a diagnostic test for the detection
of several fungal diseases, including the disease that causes black rot in
potatoes. These potatoes may appear perfectly healthy, but once they reach the
processor or consumer a tell-tale black spot will be found in the center of the
potato.
 
     The Company's test kits help ensure the quality and safety of final plant
products and also help the producer limit the amount of pesticides applied
during the production cycle. This helps reduce the likelihood of pesticide
residues in 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. The Company began this year building the sales and
marketing organization to serve this industry and management expects product
demand will grow over the next several years.
 
     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 a 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.
 
     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.
 
                                       19

PRODUCTS
 
     The Company's products are grouped into two areas: disposable diagnostic
test kits and veterinary instruments. The test kit products are generally the
result of biotechnology discoveries that allow customers to detect natural
toxins, bacteria, drugs, pesticides and determine general quality
characteristics. These products are the result of efforts by chemists,
microbiologists and immunologists. The Company's veterinary instruments are the
result of engineering and manufacturing expertise to develop safe, unique and
durable metal instruments.
 
  DIAGNOSTIC TEST KITS
 
     The Company has developed and markets over 140 separate diagnostic test
kits used in food safety, plant diseases, animal health, 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 these analytes at the parts per
billion levels. All the products are single use and allow customers to conduct
tests more rapidly than with older conventional testing methods. The test kits
are also 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. By monitoring for these bacteria,
food processors can minimize their potential impact. 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 and E. coli O157:H7.
Company scientists are also developing test kits for other harmful bacteria that
are expected to be completed during the current fiscal year. Through a marketing
agreement with Merck KGaA, the Company also has the distribution rights to the
U. S. food industry for Merck's product, HY-LITE(R), which is used to detect
general plant sanitation levels.
 
     The Company's Veratox(R) and 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, zerealenone, ochratoxin 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.
 
     Plant Diseases. Marketed under the tradename Alert(R), the Company has
several diagnostic tests that are used to detect plant diseases that affect crop
production as well as the quality and safety of the ensuing food products. These
quick 10 minute 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.
 
     Animal Health. Under the ELISA Technologies(R) tradename, 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.
 
     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.
 
     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.
 
     Sold under its ELISA Technologies tradename, the Company 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 K-Gold, the Company
sells reagents used by others in diagnostic test kit manufacturing.
 
     Sales of this class of products accounted for approximately 62%, 63% and
70% of the Company's total revenues for fiscal years 1994, 1995 and 1996,
respectively.

  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, 1994, 1995 and 1996, sales of veterinary
instruments as a percentage of total revenues were 37%, 34% and 29%,
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 in development of new products based on the Company's existing
technologies. The Company employs 17 individuals in its research and development
department, including immunologists, chemists, engineers and microbiologists.
Research and development expenditures were approximately $856,000, $1.1 million
and $1.2 million, representing 8%, 10% and 10% of total revenues in fiscal 1994,
1995 and 1996, respectively. The Company currently intends to maintain its
research and development expenditures at approximately 10% of total revenues.
 
     The Company has ongoing development projects for new immunoassay diagnostic
tests for the food safety and pharmacologics markets, as well as development
projects for new and improved veterinary instruments. Current and ongoing
research and development projects include:
 
     U.S. Department of Agriculture Grant. The Company continues to work on a
grant from the U.S. Department of Agriculture for the development of a
time-temperature test device. This simple device, if perfected, could be used
for accurate assessment or monitoring of a fast-food restaurant's cooking
process and equipment. Research on this project is expected to continue
throughout fiscal 1997. There can be no assurance that this product will
ultimately be successfully developed or marketed.
 
     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 its 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 1994,
1995 and 1996, royalty payments under these agreements amounted to $476,159,
$521,690 and $579,045, respectively.
 
SALES AND MARKETING
 
     The Company has chosen to organize its sales efforts according to market
segments rather than by product or geographic orientation. Management believes
that this strategy has been partially responsible for its revenue growth and
market share increases. 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 these individual customers also help the Company
identify new diagnostic test products that can be useful.
 
     During the fiscal year ended May 31, 1996, the Company had in excess of
1,000 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 fiscal 1996 accounted for
21% of the Company's consolidated revenues. See Note 9 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 70
countries through its own sales force, as well as through distributors in
certain geographic areas. Forty-nine people, or approximately 30% of
 
                                       23
<PAGE>   26
 
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 Diagnostic 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. These products are
all sold directly to end-users in the U.S. Sales organizations are maintained
for: grain, nut and spices; meat, poultry and eggs; fruits and vegetables; and
seafood.
 
     Veterinary Instruments. The animal health distribution market is well
organized in most countries of the world. Consequently, 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 this product line
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 well established 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 20 patents and 24
trademarks, and has several pending patents and trademarks. The patents expire
at various times over the next 20 years, beginning in 1997.
 
     The Company has no material pending litigation as to proprietary rights to
its products which poses a significant threat to its operations, and 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 numerous patents have been issued. In
addition, patent litigation (none involving the Company or its products)
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 only Company products requiring regulatory approval are Bot
Tox-B(R) and serological test kits sold to human clinical laboratories (which
were acquired via the Company's acquisition of AMPCOR, Incorporated). On a
combined basis, sales for these products amounted to less than 10% of total
sales in fiscal year 1996. The Company's strategy is to select products on the
fringe of regulatory approval areas 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.

MANUFACTURING
 
     The Company manufactures its products in Lansing, Michigan, Lexington,
Kentucky, Bridgeport, New Jersey, and Schiller Park, Illinois. There are
currently 73 full-time employees assigned to manufacturing in these four
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 two 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 related
products marketed by ELISA Technologies. 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 ELISA Technologies personnel in the Lexington facilities.
 
     The Bridgeport, New Jersey facility manufactures all of the Company's
one-step diagnostic tests for the detection of microorganisms as well as test
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 diagnostic test kits and veterinary instrument 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 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.

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. Though
less than 10% of the Company's revenue is currently derived from products
requiring government approval prior to sale, a significant portion of its
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.
 
EMPLOYEES
 
     As of August 31, 1996, the Company employed approximately 160 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 confidentiality
agreements with the Company.
 
PROPERTIES
 
     The Company's corporate offices and Michigan-based manufacturing and
research facilities are maintained in a 25,000 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. In fiscal 1996, the Company purchased
additional facilities comprising 1,100 square feet within one block of the
existing corporate headquarters. The new facility is used for offices to
accommodate eight 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 ELISA Technologies operations are maintained in 9,000 square feet of
leased space on two floors of 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. The lease
agreement provides for annual lease payments, including all utilities, of
$57,600 for the first year and increasing by $1,200 per year each year
thereafter.
 
     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. The lease agreement
provides for annual lease payments of $37,585 plus additional rent equal to
$7,334 per year with the additional rent subject to annual increase based upon
actual increases to certain operating expenses.
 
     Management believes that the Company's operating facilities are suitable
for conducting its current and anticipated business.
 
LEGAL PROCEEDINGS
 
     Although the Company is a party to ordinary routine litigation incidental
to its business, there are no pending material adverse legal proceedings.
 
INSURANCE
 
     The Company maintains product liability insurance on all products with a
coverage limit of $2 million per occurrence. In addition, the Company also
maintains insurance in amounts and types which the Company believes to be
customary in its industry.

                                   MANAGEMENT
 
     The Company's Articles of Incorporation provide for a five to nine member
Board of Directors at the discretion of the then existing Board. Directors are
elected to one-year terms of office. The executive officers of the Company are
elected to serve until removed at the discretion of the Board. The Board of
Directors has also named a Scientific Review Council to serve at the pleasure of
the Board. The Scientific Review Council meets approximately 6 times annually to
review the research progress of the Company and to recommend or approve new
research and product development activities of the Company. The following table
sets forth certain information with respect to the directors, executive officers
and other key individuals of the Company as of October 11, 1996.

                              CERTAIN TRANSACTIONS
 
     Dr. Leonard E. Heller, a member of the Board of Directors, and Terri A.
Juricic, a Vice President of the Company, owned 55% and 20%, respectively, of
WTT Incorporated, a Kentucky-based company which sold immunoassay diagnostics
for agricultural and research markets. In September 1992, the Company acquired
substantially all of the assets of WTT. The purchase price consisted of an
initial payment of cash and stock and a secondary payment of stock in October
1993, which resulted in total consideration of approximately $1,120,000. It is
estimated that Dr. Heller's share of this transaction, after deducting
liabilities of WTT not assumed by the Company, was approximately $313,000 in
cash and 42,767 shares of the Company's Common Stock. It is estimated that Ms.
Juricic's share of this transaction, after deducting liabilities of WTT not
assumed by the Company, was approximately $114,000 in cash and 15,552 shares of
the Company's Common Stock.
 
     Martin R. Gould and Sudhakar L. R. Vulimiri, Vice Presidents of a
wholly-owned subsidiary of the Company, owned 32% and 20%, respectively, of
AMPCOR, Incorporated, a New Jersey-based company which sold diagnostic test kits
to detect microorganisms. In August 1994, the Company acquired substantially all
of the assets of AMPCOR, Incorporated. The initial purchase price consisted of a
payment of cash, stock, and assumption of certain liabilities which resulted in
total consideration of approximately $1,760,600 (See Note 3 of the Notes to the
Company's Consolidated Financial Statements). It is estimated that Mr. Gould's
share of this transaction, after deducting liabilities of AMPCOR, Incorporated
not assumed by the Company, was approximately $104,000 consisting of 17,800
shares of the Company's Common Stock. It is estimated that Mr. Vulimiri's share
of this transaction, after deducting liabilities of AMPCOR, Incorporated not
assumed by the Company, was approximately $65,000 consisting of 11,000 shares of
the Company's Common Stock.
 
     Jack C. Parnell, a Company director, is a governmental relations advisor to
the law firm of Kahn, Soares & Conway. Kahn, Soares & Conway has been retained

                          DESCRIPTION OF CAPITAL STOCK
 
     The Company's authorized capital stock consists of 10,000,000 shares of
common stock, $.16 par value. The following description of certain matters
relating to the capital stock of the Company is a summary and is qualified in
its entirety by the provisions of the Company's Articles of Incorporation.
 
COMMON STOCK
 
     The Company had 4,598,042 shares issued and outstanding immediately prior
to the date of this Prospectus. Holders of Common Stock are entitled to one vote
for each share held on all matters submitted to a vote of stockholders and do
not have cumulative voting rights. Accordingly, holders of a majority of the
outstanding shares of Common Stock entitled to vote in any election of Directors
may elect all of the Directors standing for election.
 
     Holders of Common Stock are entitled to receive ratably such dividends, if
any, as may be declared by the Board of Directors out of funds legally available
therefor. Upon the liquidation, dissolution or winding-up of the Company,
holders of Common Stock are entitled to receive ratably the net assets of the
Company available for distribution after the payment of all debts and other
liabilities of the Company. Holders of Common Stock have no preemptive,
subscription, redemption or conversion rights. The outstanding shares of Common
Stock are, and the shares offered hereby will be, when issued and paid for,
fully paid and nonassessable.
 
MICHIGAN LEGISLATION/CERTAIN PROVISIONS OF THE MICHIGAN BUSINESS CORPORATION ACT
 
     The Company is subject to the provisions of Chapter 7A of the Michigan
Business Corporation Act ("MBCA") which applies to certain "Business
Combinations", defined to include a range of significant transactions such as
mergers, substantial sales of assets or securities issuances and liquidation,
recapitalization or reorganization plans. In general, Chapter 7A requires, for
any Business Combination with an "Interested Shareholder" (generally a
beneficial owner of 10% or more of the voting power of the Company's outstanding
voting stock), an advisory statement from the Board of Directors, the approval
of holders of at least 90% of the outstanding shares of each class of Company
voting stock and the approval of two-thirds of the holders of outstanding shares
of each such class, excluding those held by the Interested Shareholder, its
affiliates and associates. These requirements do not apply, however, where the
Interested Shareholder satisfies certain "fair price" form of consideration and
procedural requirements specified in the Chapter (including a requirement that
the Business Combination not occur within five years of attainment of Interested
Shareholder status) or where the Company's Board has approved the transaction
specifically, generally or generally by type prior to the Interested Shareholder
becoming an Interested Shareholder. Chapter 7A would cease to apply to the
Company if its Charter were amended to elect not to be covered by the Chapter,
but such an amendment would require the same votes for approval as the Chapter
requires for approval of a Business Combination with an Interested Shareholder.
 
     The Company also is subject to Chapter 7B of the MBCA. Generally, Chapter
7B would divest of all voting rights any shares of the Common Stock acquired in
a "Control Share Acquisition", defined, subject to certain exclusions (including
an exclusion for a merger or consolidation to which the Company is a party), as
any acquisition of issued and outstanding "Control Shares", unless and until a
majority of all shares, and of all non-"Interested Shares", approve such voting
rights. In general, "Interested Shares" are shares owned or controlled as to
voting power by employee-directors of the Company, certain of its officers, the
entity making or proposing to make the Control Share Acquisition or its
affiliates. "Control Shares" are defined as shares that, when added to those
already owned or controlled as to voting power by an entity, would (if not for
the Chapter) give the entity voting power in the election of directors of the
Company within any of three thresholds: one-fifth, one-third and a majority. If
a Control Share Acquisition is approved as required by Chapter 7B, the Chapter
would afford special dissenters' rights to Company shareholders thereafter. By
an amendment to its Articles of Incorporation or Bylaws electing not to be
covered, either the Company's Board of Directors or its shareholders could cause
the Chapter to be inapplicable to Control Share Acquisitions
 
                                       33
<PAGE>   36
 
occurring hereafter, for as long as such amendment continued in effect. The
Board currently has no plans to effect any such amendment, nor is it aware of
any other plans or proposals to do so.
 
     The MBCA also contains certain "anti-greenmail" provisions, intended
generally to limit a covered corporation's ability to purchase shares from a 3%
or more shareholder at a premium over market price absent some form of prior
approval by the corporation's shareholders. These provisions are only triggered,
however, where the corporation has a class of securities listed on a national
securities exchange. Currently, the Company has no such class of listed stock
and no intention of effecting any such listing.
 
     The foregoing discussion concerning the Common Stock and provisions of the
MBCA is qualified in its entirety by reference to pertinent sections of the
Company's Articles of Incorporation and to such MBCA provisions, respectively. A
copy of the Articles of Incorporation is on file with the Commission as an
exhibit to the Registration Statement. See "Additional Information."
 
     Under Sections 561-571 of the MBCA, directors and officers of a Michigan
corporation may be entitled to indemnification by the corporation against
judgments, expenses, fines and amounts paid by the director or officer in
settlement of claims brought against them by third persons or by or in the right
of the corporation if those directors and officers acted in good faith and in a
manner reasonably believed to be in, or not opposed to, the best interests of
the corporation or its shareholders.
 
     The Company is obligated under its bylaws to indemnify any present or
former director, officer or employee of the Company to the fullest extent now or
hereafter permitted by law in connection with any actual or threatened civil,
criminal, administrative or investigative action, suit or proceeding arising out
of their past or future service to the Company or a subsidiary, or to another
organization at the request of the Company or a subsidiary.
 
     In addition, the MBCA permits a Michigan corporation to limit the personal
liability of directors for breach of their fiduciary duty. The Company's
Articles of Incorporation so limit the liability of its directors to the maximum
extent permitted by Michigan law.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling the
registrant pursuant to the foregoing provisions, the registrant has been
informed that in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Company's Common Stock is American
Stock Transfer and Trust Company of New York.

</TABLE>
 
     The Underwriting Agreement provides that all of the Common Stock being
offered, excluding shares covered by the over-allotment option granted to the
Underwriters, must be purchased if any are purchased.
 
     The Company has been advised that the several Underwriters propose to offer
the Common Stock to the public at the public offering price set forth on the
cover page of this Prospectus and may offer to selected dealers at such price
less a concession of not more than $     per share; that the Underwriters may
allow and such dealers may reallow a concession of $     per share on sales to
certain other dealers; and that the public offering price and concessions and
reallowances to dealers may be changed by the Underwriters.
 
     The Company has granted to the Underwriters options to purchase up to an
additional 225,000 shares of Common Stock at the public offering price, less the
underwriting discounts and commissions, shown on the cover page of this
Prospectus, solely to cover over-allotments, if any. The options may be
exercised at any time up to 30 days after the date of this Prospectus. To the
extent that such option is exercised, each Underwriter will become obligated,
subject to certain conditions, to purchase approximately the same percentage of
such additional shares as the number set forth in the table above bears to the
total number of shares of Common Stock offered.
 
     The Underwriting Agreement provides that the Company will indemnify the
several Underwriters against certain liabilities, including civil liabilities
under the Securities Act, or will contribute to payments the Underwriters may be
required to make in respect thereof.
 
     All of the executive officers and directors of the Company have agreed not
to offer, sell, contract to sell, or grant any option to purchase or otherwise
dispose of any of the shares of Common Stock during the period of 90 days after
the date of this Prospectus without the prior written consent of Roney & Co. and
The Ohio Company ("Representatives"). The Company has further agreed not to
offer, sell, contract to sell, or otherwise dispose of any shares of Common
Stock or any securities convertible into shares of Common Stock (except pursuant
to employee and director stock plans or in consideration of acquisitions) for a
period of 90 days after the date of this Prospectus without the prior written
consent of the Representatives.
 
     In connection with this offering, the Underwriters and selling group
members (if any) may engage in passive market making transactions in the shares
of Common Stock on the Nasdaq National Market immediately prior to the
commencement of sales in this offering, in accordance with Rule 10b-6A under the
Exchange Act. Passive market making consists of displaying bids on the Nasdaq
National Market limited by the bid prices of independent market makers and
purchases limited by such prices and effected in response to order flow. Net
purchases by a passive market maker on each day are limited to a specific
percentage of the
 
                                       35

passive market maker's average daily trading volume in the shares of Common
Stock during a specified prior period and must be discontinued when such limit
is reached. Passive market making may stabilize the market price of the shares
of Common Stock at a level above that which might otherwise prevail and, if
commenced, may be discontinued at any time.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
To the Board of Directors and Stockholders
Neogen Corporation
Lansing, Michigan
 
     We have audited the accompanying consolidated balance sheets of Neogen
Corporation and subsidiaries as of May 31, 1995 and 1996, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended May 31, 1996. 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, 1995 and 1996, and the results of their
operations and their cash flows for each of the three years in the period ended
May 31, 1996 in conformity with generally accepted accounting principles.

                 (INFORMATION WITH RESPECT TO THE THREE MONTHS

1. SUMMARY OF ACCOUNTING POLICIES
 
  Nature of Operations
 
     Neogen Corporation and subsidiaries (the Company) develop, manufacture, and
sell products to control residues and improve quality for the agriculture,
pharmacologics, food and environmental industries. The Company's products are
currently used for animal health applications, food and environmental 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.
 
  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 cash and equivalents, 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.
 
  Cash Equivalents
 
     Cash equivalents are short-term, highly liquid investments consisting of
primarily money market funds, certificates of deposit and commercial paper.

</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 $258,644, $336,204 and $320,869 for the
years ended May 31, 1994, 1995 and 1996, and $92,234 and $96,384 for the three
months ended August 31, 1995 and 1996, 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 over the remaining
lives of the goodwill. If necessary, impairment will be measured based on the
difference between undiscounted 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.
 
  Revenue Recognition
 
     The Company recognizes product sales at the time of shipment. Contract
revenues are recognized as services are performed using the percentage of
completion method and/or upon achievement of certain levels of performance as
specified in the contracts.
 
  Net Income (Loss) Per Share
 
     Net income (loss) per share amounts are computed based on the weighted
average number of common shares outstanding, adjusted to reflect the assumed
exercise of outstanding stock options and warrants, to the extent these items
had a dilutive effect on the computations. Shares used in the computation were
4,520,743, 4,674,792 and 4,513,817 for the years ended May 31, 1994, 1995 and
1996, and 4,695,271 and 4,770,283 for the three months ended August 31, 1995 and
1996, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
                 (INFORMATION WITH RESPECT TO THE THREE MONTHS

  Recent Accounting Pronouncements
 
     The Financial Accounting Standards Board (FASB) has issued Statement of
Financial Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and Long-Lived Assets Being Disposed Of," which provides
guidance on how and when impairment losses are recognized on long-lived assets.
This statement was adopted June 1, 1996 and did not have a material impact on
the Company.
 
     The FASB has issued SFAS No. 123, "Accounting for Stock-Based
Compensation," which establishes a fair value based method of accounting for
stock-based compensation plans. This statement provides a choice to either adopt
the fair value based method of accounting or continue to apply APB Opinion No.
25, which would require only disclosure of the proforma net income and earnings
per share, determined as if the fair value based method had been applied. The
Company adopted this statement June 1, 1996 and continues to apply APB Opinion
No. 25.
 
  Unaudited Interim Financial Information
 
     The unaudited interim consolidated financial statements for the three
months ended August 31, 1995 and 1996 include all adjustments, consisting of
normal recurring accruals, which the Company considers necessary for a fair
presentation of the consolidated financial position and the consolidated results
of operations for the periods presented. The interim period results are not
necessarily indicative of the results of operations for a full fiscal year.
 
2. RESTRUCTURING CHARGES
 
     In May 1996, the Company recorded charges of $695,500 related to a
restructuring program for certain of its operations. The restructuring charges
include $437,700 related to inventory valuation adjustments and writedowns to
exit its electronic instruments operations, $205,300 related to veterinary
instrument sales group reorganization and $52,500 of other costs. The
restructuring program resulted in liabilities of $217,794 at May 31, 1996. The
majority of these liabilities are expected to be paid or settled during the 1997
fiscal year.
 
3. ACQUISITIONS
 
     Effective June 15, 1995, Neogen acquired certain assets of International
Diagnostic Systems Corp. (IDS) of St. Joseph, Michigan. The acquisition was
accounted for by the purchase method and all acquired assets, consisting of
inventory and technology for 35 different diagnostic tests used to detect drugs
of abuse in animals, were moved to the Company's ELISA Technologies division in
Lexington, Kentucky.
 
     The purchase price consisted of initial consideration of approximately
$680,000 paid in cash at closing resulting in goodwill of approximately
$622,000. The Company made a second and final cash payment of approximately
$53,000 in July 1996 based upon sales performance for the twelve month period
ended June 14, 1996.

AMPCOR Diagnostics, Inc., acquired substantially all of the assets of AMPCOR,
Inc., a New Jersey-based company that develops and manufactures diagnostic test
kits to detect the presence of harmful microorganisms.
 
     The initial purchase price for the assets of AMPCOR was $1,760,610, which

common stock valued at $325,000. In addition, Neogen incurred $110,000 of
acquisition costs and organization expense in connection with this asset
purchase.
 
     The acquisition was effective August 1, 1994, and has been accounted for
using the purchase method of accounting. Accordingly, the results of operations
of AMPCOR have been included with those of Neogen for periods beginning August
1, 1994. The excess acquisition cost over the fair value of the acquired net
assets approximated $730,000.
 
     The purchase agreement provided for the payment of additional
consideration, contingent upon the sales and profit performance of AMPCOR for
two consecutive twelve month periods ending July 31, 1995 and 1996. The Company
did not pay any additional consideration on the basis of AMPCOR's performance
for the first twelve month period ended July 31, 1995. Management expects any
second year payment to be minimal.
 
     Effective October 1, 1993, Neogen acquired substantially all of the assets
of Enzytec, Incorporated of Kansas City, Missouri. Enzytec marketed rapid
diagnostic screening tests for the detection of insecticide residues in food and
the environment. The acquisition was accounted for by the purchase method and
the results of operations have been included in the accompanying consolidated
financial statements from the date of the acquisition. All the acquired assets
were moved to Neogen's headquarters in Lansing, Michigan.
 
     The initial purchase price of $226,000 consisted of $21,000 paid in cash,
issuance of 74,626 shares of Neogen common stock, and issuance of warrants to
purchase 50,374 shares of Neogen common stock after October 31, 1994 at an
exercise price of $4.82 per share. The purchase price in excess of the fair
value of the acquired net assets was $197,922.
 
     During fiscal 1994, the Company issued 148,534 shares of its common stock
as final consideration for acquisitions made in prior years.

$153,781 and $240,533 for the three months ended August 31, 1995 and 1996,
respectively.
 
     The Company leases office and manufacturing facilities under noncancelable
operating leases. Rent expense for the years ended May 31, 1994, 1995 and 1996
was $149,000, $202,000 and $221,000, respectively. Rent expense was $42,000 and

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, 1996, the Company has net operating loss carryforwards of
approximately $4,400,000 for income tax purposes which expire between 2002 and
2008. Due to changes in ownership of the Company, utilization of $2,017,000 of
the tax net operating loss carryforward is limited to approximately $730,000 per
year. The remaining $2,383,000 may be utilized without limitation. In addition,
the Company has approximately $250,000 of tax credit carryforwards, the majority
of which expire between 1998 and 2010. Approximately $21,000 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 are as follows:

</TABLE>
 
     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 and utilization of certain carryforwards is limited to
specific amounts each year. 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

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.

9. INDUSTRY SEGMENT INFORMATION
 
     The Company has two industry segments through which it conducts its
business - diagnostic products and veterinary instruments. The diagnostic
products segment includes test kits to detect harmful, natural toxins,
pesticides, and microorganisms. These products also include test kits for the
detection of drugs of abuse in race horses, test kits used in research by
universities and pharmaceutical companies, and test kits to detect plant
diseases in ornamental plants, turf grasses, and horticulture crops. In
addition, this segment includes electronic instruments which are primarily used
to monitor environmental conditions and predict the onset of diseases or
emergence of insects. In May 1996, the Company decided to exit its electronic
instruments operations (Note 2).
 
     The veterinary instrument segment includes veterinary instruments to
provide more precise and accurate delivery of animal health products.
 
     The following table summarizes Neogen's industry segment information:

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Neogen's Bylaws permit indemnification of officers and directors to the
fullest extent allowed by law. Under Michigan's Business Corporation Act, a
corporation may indemnify its officers and directors against expenses (including
attorneys' fees), judgments, penalties, fines and amounts paid in settlement
actually and reasonably incurred by the officer or director by virtue of his
position as an officer or director of the corporation in connection with any
threatened, pending, or completed action, suit or proceeding, whether civil,
criminal, administrative, or investigative and whether formal or informal, other
than an action by or in the right of the corporation. To be eligible for
indemnification, the officer or director must have acted in good faith and in a
manner he reasonably believed to be in or not opposed to the best interests of
the corporation or its shareholders, and with respect to a criminal action or
proceeding, the officer or director must have had no reasonable cause to believe
his conduct was unlawful. Indemnification for expenses if the officer or
director is successful on the merits in defending the action is mandatory. In
other situations, the corporation must determine eligibility based on one of
five alternative methods established in the statute. A court may order
indemnification if it determines that the person is fairly and reasonably
entitled to indemnification in view of all relevant circumstances, even if the
statutory eligibility standards are not otherwise met.

ITEM 17 UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes to supplement the prospectus,
after the expiration of the subscription period, to set forth the results of the
subscription offer, the transactions by the underwriters during the subscription
period, the amount of unsubscribed securities to be purchased by the
underwriters, and the terms of any subsequent reoffering thereof. If any public
offering by the underwriters is to be made on terms differing from those set
forth on the cover page of the prospectus, a post-effective amendment will be
filed to set forth the terms of such offering.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission,
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
 
     The undersigned registrant hereby undertakes that:
 
          1. For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          2. For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

certifies that it has reasonable grounds to believe that it meets all of the

                               LICENSE AGREEMENT

     This Agreement is entered into between the Agricultural Research Service,
an agency of the United States Department of Agriculture (hereinafter referred
to as "ARS") and Neogen Corporation, a Michigan corporation having offices at
600 Lesher Place, Lansing, Michigan (hereinafter referred to as "NEOGEN").

     WHEREAS, The United States Department of Agriculture has sponsored
research to develop a hybridoma which produces monoclonal antibodies which
recognize salinomycin and has received by assignment certain valuable patent
rights thereon in the United States; and

     WHEREAS, ARS desires, in the public interest, that the subject invention
be perfected, marketed, and practiced so that the benefits are readily
available for widest possible utilization in the shortest time possible; and

     WHEREAS, NEOGEN represents that it has the facilities, personnel and
expertise and is willing to expend reasonable efforts to bring the invention to
the point of practical application and to make the invention available to the
public;

     NOW THEREFORE, in consideration of the foregoing and pursuant to 35 USC
207 and 37 CFR 404 and the mutual promises and obligations hereinafter set
forth, ARS and NEOGEN, intending to be legally bound, agree as follows:

     5.2  NEOGEN shall submit to ARS within sixty (60) days after each calendar
half year ending June 30th and December 3 1st, reports setting forth for the
preceding six (6) month period the amount of Licensed Products made, used, or

thereof and the royalties due pursuant to Paragraph 4.4 above.  The report shall
include an itemized accounting of the number of units of Licensed Products sold,
price per unit, and each deduction taken from the gross sales for the purpose of
calculating Net Sales.  A written report shall be due for each reporting period
whether or not any royalties are due to ARS.

as are required for the determination of royalties owed to ARS pursuant to this
Agreement.  Such records shall be retained for at least five (5) years following

provisions of Paragraphs 7.3 and 12.4 below if it is determined that any one of
the following has occurred:

               specified by Federal regulations issued after the date of the

               NEOGEN, or one of its sublicensees;

          (c)  NEOGEN has willfully made a false statement or willfully omitted
               a material fact in the license application or in any report
               required by this Agreement;



                                       5
<PAGE>   6


          (d)  NEOGEN, or its sublicensees, commits a substantial breach of a
               covenant or agreement contained in this Agreement;

          (e)  NEOGEN is adjudged bankrupt or has its assets placed in the hands

          (f)  NEOGEN, or its sublicensees, misuses the Licensed Patent.

     7.3  Prior to modification or termination of this Agreement, ARS shall
furnish NEOGEN and any sublicensees of record a written notice of intention to
modify or terminate, and NEOGEN and any notified sublicensee shall be allowed
thirty (30) days after the date of receipt of such notice to remedy any breach
or default of any covenant or agreement of this Agreement or to show cause why
this Agreement should not be modified or terminated.

     7.4  NEOGEN may terminate this Agreement at any time upon ninety (90) days
written notice to ARS.  If NEOGEN terminates this Agreement in accordance with
the provisions of this Paragraph 7.4, NEOGEN shall provide ARS with all

Effective Date, and ARS shall be free to disclose such data to any third party.

     7.5  Upon termination of this Agreement, all sums due to ARS pursuant to
Article IV hereunder shall become immediately payable.  In all other respects,
the rights and obligations of the parties hereto concerning the Licensed Patent
included in such termination shall cease as of the effective date of such
termination.  NEOGEN may, however, within a reasonable time after the date of
such termination, sell all Licensed Products completed and in inventory provided
that royalties are paid on any such sales in accordance with the provisions of
Article IV.

     7.6  In the event of termination of this Agreement, any sublicense of
record granted pursuant to Paragraph 2.2 may, at the sublicensee's option,
either be converted to a license directly between sublicensee and ARS or be
terminated.


                                  ARTICLE VIII
                               Patent Enforcement



     8.1  The U.S. Government is not obligated to enforce the Licensed Patent
against infringers.  NEOGEN shall continue to pay maintenance and royalty fees
accruing to the Government until such time as this Agreement is terminated by
either party, even if the Government elects not to enforce the Licensed Patent
against infringers.

     8.2  NEOGEN is granted the first option at its own expense, in its own
name, to enforce the Licensed Patent against a specific party who may be
infringing the Licensed Patent, subject to the following conditions:

          (a)  The right of enforcement granted under this Paragraph 8.2 shall
               constitute the rights provided under Title 35, Chapter 29, of the
               U.S. Code.

          (b)  If NEOGEN elects the option against a specific party, the
               Government shall not be entitled to bring an enforcement action
               against such party except if it chooses to join with NEOGEN.

          (c)  If NEOGEN submits a written request to elect the option against a
               specific party, ARS must approve the election before NEOGEN may
               bring an enforcement action against such party.

                    (i)  If ARS does not approve the election, and can not
                    reasonably establish non-infringement, within ninety (90)
                    days of NEOGEN's request for approval, NEOGEN shall not be
                    obligated to pay royalties or fees that begin to accrue at
                    the end of the ninety day period.

                    (ii) If ARS grants approval after the end of the ninety day
                    period, NEOGEN shall be obligated to pay royalties and fees
                    that accrue beginning with the day of subsequent approval,
                    but shall not be obligated to pay royalties or fees that
                    previously accrued during the time extending from the end of
                    the ninety day period to the day of subsequent approval.

          (d)  If ARS requests in writing that NEOGEN decide whether to elect
               the option against a specific party, NEOGEN shall submit its
               decision within sixty (60) days of the date of request.  In the
               absence of a written response during the sixty day period, ARS
               may enforce the Licensed Patent without NEOGEN.

     8.3  The following conditions apply to court awards and sublicensing fees
as to the Licensed Patent, if NEOGEN elects the enforcement option against a
specific party:

          (a)  NEOGEN is not required to share, with ARS, court awards from such
               party, but is required to share sublicensing royalty fees from
               such party other than as awarded by a court.

          (b)  NEOGEN's attorney's fees for attempting to sublicense or enforce
               the Licensed Patent(s) against a specific party may be deducted
               from payments due to ARS under a sublicense to such party,
               provided that such attorney's fees are not  



                                       7
<PAGE>   8

               recouped as part of a court award for infringement of the
               Licensed Patent by such party, and provided that any such
               deductions do not exceed fifty percent (50%) of the payments due
               to ARS during any single reporting period.

     8.4  In the absence of prior written consent from ARS, NEOGEN shall not be
entitled to waive any rights in the Licensed Patent as part of an agreement with
a party who may be infringing the Licensed Patent.


                                   ARTICLE IX
                         MARKINGS AND NON-USE OF NAMES

     9.1  NEOGEN, and its sublicensees, shall mark Licensed Products or packages
containing Licensed Products with all applicable patent numbers.

     9.2  NEOGEN shall not use the name of the U.S. Government, the name of any
department or agency of the U.S. Government, the name of any U.S. Government
employee, or any adaptation of the above in any promotional activity without
prior written approval from ARS.


                                   ARTICLE X
                         REPRESENTATIONS AND WARRANTIES

     10.1 ARS represents and warrants that the entire right, title and interest
in the Licensed Patent has been assigned to the United States of America as
represented by the Secretary of  Agriculture and that ARS has the authority to

     10.2 ARS does not warrant the patentability or validity of the Licensed
Patent and makes no representations whatsoever with regard to the scope of the
Licensed Patent or that such Licensed Patent may be exploited without infringing
other patents.


                                   ARTICLE XI
                   PAYMENTS, NOTICES AND OTHER COMMUNICATIONS

     Written notices and reports required to be given under this Agreement, and
submission of execution and maintenance fees and royalties, shall be mailed by

                               GENERAL PROVISIONS

     12.1 This Agreement shall not be transferred or assigned by NEOGEN to any
party other than to a successor or assignee of the entire business interest of
NEOGEN relating to the Licensed Patent.  NEOGEN shall notify ARS in writing
prior to any such transfer or assignment.

     12.2 The interpretation and application of the provisions of this Agreement
shall be governed by the laws of the United States as interpreted and applied by
the Federal courts in the District of Columbia.

     12.3 Neither party may waive or release any of its rights or interest in
this Agreement except in writing.  The failure of a party to assert a right
hereunder or to insist on compliance with any term or condition of this
Agreement shall not constitute a waiver of that right or excuse a similar
subsequent failure to perform any such term or condition by the other party.

     12.4 The parties shall make every reasonable effort to resolve amicably any
dispute concerning a question of fact arising under this Agreement.  Any
disputes not settled amicably between the parties concerning a question of fact
arising under this Agreement shall be decided by the Assistant Administrator for
Technology Transfer, ARS, who shall reduce his decision to writing and mail or
otherwise furnish a copy thereof to NEOGEN.  Any decision of the Assistant
Administrator, ARS, whether it be a question of fact, or to modify or terminate
this Agreement, may be appealed to the Administrator, ARS, whose decision shall
be administratively final and conclusive.  Pending final decision of a dispute
hereunder, NEOGEN shall proceed diligently with the performance of its
obligations under this Agreement.

     2. DEMISE OF PREMISES.  Landlord, for and in consideration of the Rent (as
hereinafter defined) to be paid and the covenants and agreements to be
performed by Tenant as hereinafter set forth, does hereby lease, demise and let
unto Tenant the Premises, together with the non-exclusive right to use in
common with the other tenants in the Building all common parking spaces located
adjacent to the Building, walks, access roads and land surrounding the Building
and the common areas in the Building (collectively the "Property") .

     3 . USE OF PREMISES. (a) Tenant covenants and agrees to use the Premises
for the Permitted Use, and for no other purpose or purposes.  No machinery,
equipment or other thing that could cause excessive vibration, noise, odor or
fumes shall be installed or placed therein.  Tenant shall not subject any
portion of the floor to greater loading than that portion of the Premises is
designed to carry.  Tenant agrees that all outside storage of any kind is
prohibited.  Parking of inoperable vehicles, non-motorized vehicles or trailers
in or about the Premises is prohibited.

     (b) Tenant shall, in the use and occupancy of the Premises and the conduct
of Tenant's business or profession therein, at all times and at Tenant's
expense comply with, and conform the Premises to the following requirements
(the "Requirements"): all applicable laws, ordinances, orders, notices and
regulations of the federal, state and municipal governments, or any of their
departments and the regulations of the insurers of the Premises and Building
and the rules and regulations attached hereto as Exhibit "B."  Without limiting
the generality of the foregoing, Tenant shall: (I) obtain, at Tenant's expense,
before engaging in Tenant's business or profession within the Premises, all
necessary licenses and permits including (but not limited to) state and local
use or occupancy and business licenses or permits; and (ii) remain in
compliance with and keep in force at all times all licenses, consents and
permits necessary for the lawful conduct of Tenant's business or profession at

                                       2

or imposed upon Tenant and which, if not paid, could be liened against the
Premises or against Tenants property therein or against Tenant's leasehold
estate.  Tenant agrees to promptly furnish Landlord with a copy of any notice
that it receives that it is in violation of any Requirements.

     (c) Tenant shall indemnify, protect, defend and save harmless Landlord
with regard to any non-compliance or alleged noncompliance by Tenant with any
Requirements.  If Landlord is named as defendant or a responsible party with
respect to any alleged violation or non-compliance by Tenant as aforesaid,
Landlord also may require, by notice to Tenant as aforesaid, that the matters
or conduct giving rise thereto be discontinued by Tenant unless and until the
alleged violation or non-compliance is resolved in Tenant's favor.


     4 . POSSESSION.  In no event shall Landlord be liable to Tenant for any
actual or consequential damages in the event that Landlord is unable to deliver
possession of the Premises on the Lease Commencement Date.  If the Lease term
does not commence upon the Lease Commencement Date, Landlord and Tenant shall,
by separate writing, set forth the revised Lease Commencement Date and
Expiration Date (which shall be extended accordingly).

     5 . RENT. (a) The Base Rent shall be paid without notice in equal monthly
installments on or prior to the first day of each month.  If the Rent
Commencement Date is other than the first day of a calendar month or if the
Expiration Date is other than the last day of a calendar month, Rent for such
partial month shall be prorated.  See Page 3A attached.

     (b) In addition to the Base Rent, Tenant shall pay to Landlord its Pro
Rata Share of all real estate taxes and assessments (collectively "Taxes")
incurred during each tax year (pro rated where appropriate) during the term of
this Lease.  The Taxes shall be estimated by Landlord from time to time and
Tenant shall pay to Landlord monthly, in addition to the Basic Rent and on the
same day provided in Article 5(a), 1/12 thereof.  Landlord shall have the
right, but not the obligation to appeal or contest any Taxes and Tenant shall
pay its Pro Rata Share of Landlord's costs for the contest or appeal which
costs, shall in no case ever exceed any tax savings.

     (c) In addition to the Base Rent and Taxes, Tenants are to  pay to
Landlord its Pro Rata Share of all operating costs (the "Costs") incurred
during each calendar year (pro rated where appropriate) during the term of this
Lease.  The Costs shall be estimated by Landlord from time to time and Tenant
shall pay to Landlord monthly, in addition to the Basic Rent and Taxes and on
the same day provided in Article 5(a), 1/12 thereof.  The Costs shall include
any and all costs incurred (including labor costs for Landlord's employees) in
the maintenance, repair, upkeep, replacement, servicing, securing and operation
of the Building and Property (less any charges invoiced directly to other
tenants in the Building) and shall include but not be limited to:

      (i) All costs and expenses directly related to the operation of the
      Building and Property including lighting, cleaning, maintaining and
      painting the building exterior, fire suppression and alarm systems,
      removing snow, ice and debris and maintaining all landscape areas,
      (including replacing and replanting flowers, shrubbery and trees),
      maintaining and repairing all other exterior improvements (including
      without limitation parking areas, drives and sidewalks) on the Property
      and all repairs and compliance costs (including storm water runoff etc.,

      snow removal services shall

     LANDLORD'S DEFAULT.  In the event Landlord defaults under any of it's
specific obligations set forth in this Lease, Tenant shall provide a written
notice thereof to Landlord, which notice shall specify the nature of the
default and the actions proposed by Tenant to cure such default.  Landlord
shall have a period of thirty (30) days following receipt of such notice in
which to commence and diligently pursue cure of such default and shall complete
cure within a reasonable time thereafter, failing which, Tenant shall have the
right to cure such default on behalf of Landlord on a commercially reasonable
basis. Upon effecting such cure on behalf of Landlord, Tenant shall submit a
detailed written invoice to Landlord and Landlord shall have a period of
fifteen (15) days in which to pay such invoice, failing which, Tenant shall
have the right to set off such amount against the next payment of rent owing to
Landlord under this Lease.  In the event, however, that Landlord disputes the
existence of the default claimed by Tenant in it's original notification to
Landlord, Landlord shall so notify Tenant within ten (10) days of Landlord's
receipt of Tenant's notice and in such event, the parties shall then proceed to
arbitration as to the issue of the existence of the default claimed by Tenant.
Such arbitration shall be held before a single arbitrator appointed by and
under the rules of the American Arbitration Association in Burlington County,
New Jersey.  In the event of arbitration under this paragraph, Tenant shall not
have the right to set off against rent unless and until the arbitrator rules in
Tenant's favor and Landlord fails to pay the award set forth by the arbitrator
within fifteen (15) days of the date of such decision.

         be limited to the parking areas and Tenant shall be responsible for
         its entrance ways and sidewalks.

         (ii) If the Property is located in an industrial park, Tenant shall
         pay its pro rata share of maintenance and repair of any common areas
         in the industrial park including, but not limited to drainage systems,
         lighting, trash removal, snow removal, landscaping and dues if
         applicable.

         (iii) Administrative fee of three (3%) percent of the Base Rent plus
         legal fees which are applicable to the overall operation of the
         Building.  It is expressly understood that legal fees incurred in an
         action against an individual Tenant shall not be deemed includable as
         an operating expense pursuant to this provision.

         (iv) All costs and expenses Incurred by Landlord for environmental
         testing, sampling or monitoring necessary except any costs or expenses
         incurred in conjunction with the spilling or depositing of any
         hazardous substance for which any other Tenant is legally liable.

         (v) All costs for insurance carried by Landlord.

         (vi) Capital expenditures and the costs of preparing any other unit
         for rental shall not be included as operating expenses.  However in
         the event that Landlord incurs any capital expense for an improvement
         required by virtue of any governmental statute, ordinance or
         regulation then Landlord shall be permitted to recover on an amortized
         basis (not to exceed five (5) years) the portion of the capital costs
         applicable to the term of this Lease including any renewal or
         extension.  Similarly should Landlord make any capital improvement
         which reduces the operating expenses payable hereunder then Landlord
         shall be permitted to recover the amortized costs as aforesaid but in
         no case shall the expense allocated exceed the cost savings achieved
         by the capital improvement.

     (d) Within 120 days following the end of each calendar year and/or tax
year, as the case may be, Landlord shall send to Tenant a statement of actual
Costs and/or Taxes, as the case may be, incurred for such year as appropriate,
showing the Pro Rata share due from Tenant. In the event the amount paid by
Tenant as Additional Rent for such period pursuant to this Article 5 exceeds
the amount that was actually due based upon actual year end cost, then Landlord
shall issue a credit to Tenant in an amount equal to the overcharge which
credit Tenant may apply to future rent payments until Tenant has been fully
credited with the overcharge.  If the credit due to Tenant is more than the
aggregate total of future rental payments, Landlord shall pay to Tenant the
difference between the credit in such aggregate total.  In the event Landlord
has undercharged Tenant, then Landlord shall send Tenant an invoice with the
additional amount due which amount shall be paid in full by Tenant within ten
(10) days of receipt.

     (e) All Taxes, Costs and other sums other than Base Rent payable by Tenant
to Landlord under this Lease shall be deemed additional rent ("Additional
Rent") and Landlord shall have all rights with respect to the
non-payment of Additional Rent as for Base Rent.  Base Rent and Additional Rent
are sometimes herein together called "Rent".

     6 . LATE PAYMENT .   For each payment of Rent received after  the first
day following the due date therefor, Tenant shall pay to Landlord an initial
late charge of five percent (5%) of the payment due plus one and one-half
(1-1/2%) percent for each additional month such payment is late, which charge
must accompany the late payment.  An additional charge will be made for checks
returned for insufficient funds.

     7 . SECURITY DEPOSIT.  Tenant does herewith deposit with Landlord the
Security Deposit to be held as security for the full and faithful performance
by Tenant of Tenant's obligations under this Lease and for the payment of
damages to the Premises.  Except for such sum as shall be applied by Landlord
to satisfy claims against Tenant arising from defaults under this Lease or by
reason of damages to the Premises, and further provided that Tenant is not then
in default hereunder and has complied with all obligations for surrender and
redelivery of the Premises to Landlord [including without limitation all
obligations contained in Article 15 (c) ], the Security Deposit shall be
returned to Tenant without Interest within thirty (30) days of the expiration
of the term of this Lease or any renewals or extensions thereof.  It is
understood that no part of any Security Deposit is to be considered as the last
rental due under the term of the Lease.  Notwithstanding any law to the
contrary, Landlord shall not be required to pay any interest to Tenant on
account of the holding of the Security Deposit and need not maintain this
deposit in a separate account but may co-mingle and use these funds as its own.
In the event of the sale or transfer of Landlord's interest in the Building,
Landlord shall have the right to transfer the Security Deposit to such
purchaser or transferee, in which event Tenant shall look only to the new
Landlord for the return of the Security Deposit and Landlord shall thereupon be
released from all liability to Tenant for the return of the Security Deposit.

     8 . SIGNS.  No sign, advertisement or notice shall be affixed to or placed
upon any part of the Premises, Building or Property by the Tenant or anyone
acting under Tenant.  At any time Landlord may put upon the Premises a suitable
"for sale" sign and for six (6) months prior to the expiration of the current
term, Landlord or it agents may place the usual "to let" signs thereon.
Landlord shall provide Landlord's standard signage identifying Tenant on
Building pylon and at suite entrance.

     9. SERVICES AND UTILITIES.  The Tenants shall pay all costs and charges
for utilities and services including security deposits and minimum fees.  The
utilities shall be deemed to include without limitation the cost of heating,
air conditioning if applicable, electricity, water, gas, sprinkler stand-by
fee, sewer service and septic fee if applicable.  The Landlord shall not be
liable for any interruption or delay in any of the above services for any
reason.  Upon demand, Tenant shall promptly furnish to Landlord payment or
evidence of payment of charges for utilities and services.

     10. CONDITION OF PREMISES. (a) If landlord agrees to complete any work in
the Premises prior to occupancy by Tenant, then the specifications for such
construction shall be as set forth on the construction documents initialed by
the parties and incorporated by reference into this Lease on Exhibit "C".  The
taking of possession of the Premises by Tenant shall conclusively establish
that the Premises and the Building were at such time in satisfactory condition,
order and repair, subject to any punch list items.

     (b) Landlord shall undertake warranty work described in Exhibit "D" (if
any) and except as set forth therein Tenant is leasing the Premises in their
"as-is" condition.

     11. SURRENDER.  Tenant shall at the expiration of Term, hereof, peaceably
surrender possession of the Premises in as good and marketable order and
condition as existed at the inception of this Lease, reasonable wear and tear
of the finishing elements and carpeting and damage by fire, elements or
casualty excepted, and will, at the expiration of said term, or any
continuation thereof, deliver the keys at the office of said Landlord.  Within
the final fifteen (15) days of the Term, the systems shall be inspected by a
reputable electrical, mechanical or plumbing contractor designated by Landlord
at the sole cost and obligation of Tenant.  All mechanical, electrical,
plumbing, heating and air conditioning 



                                      5
<PAGE>   9

systems shall be in good operating order at the termination of this Lease and 
Tenant shall perform a thorough cleaning of the Premises immediately prior to   
surrender, including without limitation shampoo and repairs of all carpeted
areas of the Premises.  Any property or fixtures which remain upon the Premises
after the expiration of the Lease shall be deemed abandoned by Tenant and
Landlord may take possession of same and dispose of same in any reasonable
manner without any further liability of Landlord to Tenant.  Any costs
associated with the removal of such property shall be payable by Tenant.

     12. REPAIRS AND MAINTENANCE. (a) Except as specifically otherwise provided
in subsection (b) of this Article 12, Tenant, at its sole cost and expense and
throughout the term of this Lease shall keep and maintain the Premises
including without limitation hot water heaters, roof fans,   plumbing and
electrical systems and fixtures, Tenants improvements, betterments and other
special equipment attached to the Premises, glass, overhead doors, loading dock
bumpers and revelers and carpeting in good order and condition, free of dirt
and rubbish, and shall promptly make all repairs necessary to keep and maintain
such good order and condition, whether such repairs are ordinary or
extraordinary, foreseen or unforeseen.  When used in this Article 12, the term
"repairs" shall include replacements and renewals when necessary.  All repairs
made by Tenant shall utilize materials and equipment which are at least equal
in quality and usefulness to those originally used in constructing the Building
and the Premises. Tenant shall also repair and maintain any openings in the
roof or walls specifically installed by or for Tenant with Landlord's prior
written consent. Tenant shall pay Landlord's costs to service, repair and
maintain HVAC Equipment including any underground storage tank and associated
piping, any fire suppression system (including alarm monitoring) and any other
service which pertains to the Property.  Tenant shall have the option to
purchase and maintain its own service contract on the HVAC Equipment so long as
Landlord has given its prior written consent to the service agreement.

     (b) Landlord, throughout the term of this Lease shall make all necessary
repairs to the footings and foundations, roof, external walls and structural
steel columns and girders forming a part of the Premises (excluding doors,
windows and other apertures); provided, however, that Landlord shall have no
responsibility to make any repair unless and until Landlord receives written
notice of the need for such repair from Tenant.  Tenant shall pay the
cost of any repairs made pursuant to this paragraph as same are occasioned by
the act, omission or negligence of Tenant, its employees or invitees.

     13. ALTERATIONS AND TRADE FIXTURES. (a) Tenants shall not make any
alterations, additions, or improvements (collectively "Alterations") to the
Building or Property and shall not make any Alteration to the Premises without
Landlord's prior written consent.  All Alterations made by either of the
parties hereto upon the Premises, except moveable and detached or detachable
office furniture, partitions, and machinery and equipment put in at Tenant's
expense AND EXCEPT FOR FIXTURES IDENTIFIED IN EXHIBIT "G", shall be the
property of Landlord, and shall remain upon and be surrendered with the
Premises, as part thereof at the termination of this Lease.  Any damages caused
by or arising from the Tenant's removal of any Alterations shall be restored or
repaired at Tenant's expense.

     (b) All labor and materials furnished by or on behalf of Tenant under or
pursuant to this Lease shall be first class, not less than the caliber and
quality which exists in the Premises and by contractors approved in writing by
Landlord and shall be accomplished at times so as not to disturb the business
of other tenants.  Tenant shall not install any Alterations in such a manner


                                      6

<PAGE>   10


as to compromise the structural integrity or impair the economic value or
marketability of the Premises or any part thereof.  The labor and materials
shall be installed in complete conformity to all applicable statutes, codes,
ordinances and regulations.

     (c) Landlord agrees that it will not unreasonably withhold or delay its
consent to any interior nonstructural Alterations to the Premises which do not
affect any Building systems.  Tenant agrees that it will submit to Landlord
sealed plans and specifications along with the name and address of the proposed
contractor and all subcontractors as part of any request made hereunder.  Prior
to commencing the work, Tenant will furnish Landlord with copies of
all governmental permits, certificates establishing that its contractor and
subcontractors have adequate insurance coverages naming Landlord (and any
property manager) and Landlord's mortgagee as additional insureds and a waiver
of lien.  If the Landlord has installed a master lock system Tenant agrees that
under no circumstance will it change any of the exterior locks thereby making
it impossible for the Landlord to gain access with its master key.

     14. ACCESS TO PREMISES.  Landlord, its employees and agents shall have the
right to enter the Premises at all reasonable times for the purpose of
examining or inspecting the same, showing the same to prospective purchasers,
mortgagees or tenants of the Building, and making such alterations, repairs,
improvements or additions to the Premises or to the Building as may be
necessary.  If representatives of Tenant shall not be present to open and
permit entry into the Premises at any time when such entry by Landlord is
necessary or permitted hereunder, Landlord may enter by means of a master key
(or forcibly in the event of an emergency) without liability to Tenant and
without such entry constituting an eviction of Tenant or termination of this
Lease.

     15. ENVIRONMENTAL COMPLIANCE.  TENANT HEREBY AGREES THAT IT SHALL COMPLY,
AT IT'S SOLE COST AND EXPENSE, WITH THE REQUIREMENTS OF ALL FEDERAL, STATE AND
LOCAL ENVIRONMENTAL LAWS, RULES, ORDINANCES, REGULATIONS AND ORDERS WITH

EXAMPLE, THE CLOSURE OF TENANT'S OPERATIONS, THE SALE OF THE PROPERTY OR
OTHERWISE).  TENANT HEREBY AGREES TO INDEMNIFY, DEFEND AND HOLD HARMLESS
LANDLORD FROM AND AGAINST ANY AND ALL CLAIM,

DAMAGE, LOSS, COST, FINE, PENALTY, FEE OR EXPENSE OF ANY NATURE INCLUDING
WITHOUT LIMITATION, ALL REASONABLE ATTORNEYS, CONSULTANTS, AND OTHER FEES AND
COSTS OF ANY NATURE, ARISING, DIRECTLY OR INDIRECTLY, OUT OF (I) ANY BREACH BY
TENANT OF ANY OF ITS OBLIGATIONS NOT FORTH UNDER THIS PARAGRAPH; (II) ANY
ENVIRONMENTAL CONDITION AT THE PROPERTY, OR OTHERWISE, ARISING OUT OF TENANT'S
USE OF THE PREMISES OR TENANT'S OPERATIONS; (III) ANY CLAIM BY ANY THIRD PARTY,
LANDLORD OR ANY GOVERNMENTAL AUTHORITY ARISING OUT OF ANY ENVIRONMENTAL
CONDITION AT THE PREMISES OR ARISING OUT OF TENANT'S OPERATIONS. (See Paragraph
15 Addendum immediately following.)

     16. ASSIGNMENT AND SUBLETTING. (a) Tenant shall have no right to assign or
sublet by operation of law or otherwise, all or any part of the Premises
without the prior written approval of Landlord.

     (b) In the event Tenant desires to sublet the Premises or assign the
Lease, Tenant shall give to Landlord written notice of Tenant's intended
subtenant or assignee in order to secure Landlord's written consent within
ninety (90) days of receipt of said notice, Landlord shall have the right: (I)
to terminate this Lease by giving Tenant not less than thirty (30) days' notice
in the case of an assignment of the entire Lease or a subletting of more than
fifty percent (50%) of the Premises or (ii) to terminate this Lease and
simultaneously to enter into a new Lease with Tenant for that portion of the
demised Premises Tenant may desire to retain upon the same terms, covenants and
conditions of the existing Lease as applicable to the space retained.  If
Landlord exercises its right to terminate this Lease, Tenant agrees that
Landlord shall have access to all or a portion of the demised Premises sixty
(60) days prior to the effective termination date for remodeling or
redecorating purposes.

     (c) On any approved subletting or assignment of all or any part of the
Premises, (A) Landlord shall receive from Tenant all rent in excess of those
defined herein and other profits relating to the premises derived by Tenant
from the assignment or subletting, (B) Tenant shall remain liable under all
terms and conditions of this Lease; and (c) Landlord shall have the right to
approve the subtenant or assignee and the sublease or assignment documents (and
any assignee or subtenant must agree therein to assume all terms, conditions
and obligations of the Lease).   In the event of default by Tenant under the
terms and conditions of this Lease at such time that all or part of the
Premises are then sublet, Landlord may collect directly from the subtenant(s)
all rents becoming due to Tenant under the Sublease(s) and apply such rents
against any sums due to Landlord by Tenant under this Lease, and Tenant hereby
authorizes and directs such Subtenant(s) to make such payment of rent to
Landlord upon receipt of notice from Landlord.  Such collection of rent by
Landlord shall not constitute a novation or a release of Tenant from its
liability under the terms and conditions of this Lease.

     (d) The written approval of Landlord to one or more sublettings or
assignments shall not operate as a waiver of Landlord's right to approve any
further sublettings and assignments.

     (e) Tenant shall not (I) mortgage, pledge otherwise encumber its interest
in this Lease or (ii) grant any license, concession or other right of occupancy
of any portion of the Premises, without the prior written consent of Landlord.

     (f) As a condition precedent to Tenant's right to sublease a Premises or
to assign this Lease, Tenant shall, at Tenant's own expense, comply with ISRA.
Tenant shall promptly furnish to Landlord true and complete copies of all
documents, submissions and correspondence provided by Tenant to the Bureau and
all documents, reports, directives and correspondence provided by the Bureau to
Tenant.  Tenant shall also promptly furnish to Landlord true and

PARAGRAPH 15.  ENVIRONMENTAL COMPLIANCE - ADDENDUM

Landlord hereby acknowledges full responsibility for the integrity of any
underground storage tanks and agrees to indemnify, defend, and hold harmless
Tenant from and against any and all claims, fees, and expenses arising directly
or indirectly out of failure of the integrity of any such underground storage
tanks.  Landlord hereby agrees that Tenant is not obligated to comply with the
provisions of Paragraph 15 for any environmental condition that exists or
existed prior to the date tenant commences occupancy of the Premises.

complete copies of all sampling and test results obtained from samples and
tests taken at and around the Premises.  As a condition precedent to Tenant's
right to sublease the Premises or to assign the Lease, Tenant shall have
received from the Bureau either (I) a non-qualified approval of Tenant's
negative declaration or (ii) a non-applicability letter, for which Tenant shall
promptly apply pursuant to ISRA.  If this condition shall not be satisfied,
then Landlord shall have the right to withhold consent to sublease or
assignment.

     (g) Nothing herein to the contrary withstanding, Landlord's written
consent shall not be required for any sublease or assignment of this Lease to
any other entity which controls or is controlled by Tenant provided that Tenant
shall continue to remain liable in such instance.  Tenant shall be required to
give Landlord thirty (30) days written notice in advance of any such subleasing
or assignment.

     (h) Tenant agrees that any subleasing or assignment to any person, firm,
partnership or corporation which is not an actual user of the Premises is
absolutely prohibited and nothing herein shall require Landlord to consent to
any such assignment.  In addition, subleases or assignments are absolutely
prohibited to any person, firm, entity or corporation which (I) at such time is
a tenant in any building owned by Landlord or any affiliate of Landlord or (ii)
is currently or has within six (6) months prior to the date of the proposed
sublease or assignment actively been discussing a proposed lease with Landlord
or any affiliate of Landlord.

     17. MECHANICS'  LIENS.  If any mechanics other lein shall be filed against
the Property, Premises or the Building for labor or material furnished or to be
furnished at the request of the Tenant, then Tenant shall at its expense cause
such lien to be discharged of record by payment, bond or otherwise, within ten
(10) days after the filing thereof.  If Tenant shall fail to cause such lien to
be discharged of record within such ten (10) day period, Landlord may cause
such lien to be discharged by payment, bond or otherwise, without investigation
as to the validity thereof or as to any offsets or defenses thereto.  The cost
to Landlord for removal of such lien will be charged to Tenant as Additional
Rent and payable on the first day of the month next following the payment by
Landlord together with interest until payment at a rate (the "Rate") equal to
two percent (2%) per annum over the then domestic prime rate (the base rate on
corporate loans at large U.S. money center commercial banking) or equivalent
rate as announced daily in the Wall Street Journal under the heading "Money
Rates".  Tenant shall indemnify and hold Landlord harmless against any and all
claims, costs, damages, liabilities and expenses (including reasonable attorney
fees) which may be brought or imposed against or incurred by Landlord by reason
of any such lien or its discharge.

     18. INDEMNIFICATION AND LIABILITY INSURANCE.  (a) Tenant covenants and
agrees that it shall, at its own cost and expense, indemnify and save harmless
Landlord against and from, and Landlord shall not be liable to Tenant for, any
and all claims by or on behalf of any person, entity, firm or corporation
arising in any manner whatsoever from, out of or in connection with (a) the use
and occupancy of the Property by Tenant (b) failure to perform any of the terms
or conditions of this Lease required to be performed by Tenant, (c) any failure
by Tenant to comply with any statutes, regulation, ordinances or orders of any
governmental authority or (d) any accident, death, injury, or
damage, loss or theft of property in or about the Property (whether involving
property belonging to Tenant or any other person) resulting from any cause
whatsoever, unless such accident, death, injury, damage, loss or theft is
caused by the sole negligence of Landlord, and from and against all costs,
attorney fees, expenses and liabilities incurred in or as a result of any such
claim or action or proceeding brought  




                                      9
<PAGE>   14

against Landlord by reason of any such  claim.  Tenant, upon notice from
Landlord, covenants to resist or defend such action or proceeding by legal
counsel reasonably satisfactory to Landlord.

     (b) During the term of this Lease and any renewal thereof, Tenant shall
obtain and promptly pay all premiums for commercial general liability insurance
with respect to the Property, covering at least the hazards of
"premises/operations", "independent contractors" and "contractual liability"
with a per occurrence limit of not less than $1,000,000.00 combined bodily
injury and property damage, and an aggregate limit of not less than
$2,000,000-00, with such insurance company or companies as shall be
satisfactory to Landlord from time to time, and all such policies and renewals
thereof shall name the Landlord, its property manager and any mortgagee as an
additional insured and shall contain IF AVAILABLE WITHOUT SUBSTANTIAL
ADDITIONAL COSTS TO TENANT, a breach of warranty endorsement that the coverage
shall not be voided as to Landlord for any misrepresentation, act or omission
of Tenant.  ON OR BEFORE THE COMMENCEMENT DATE OF THE TERM OF THIS LEASE, AND
THEREAFTER NOT LESS THAN FIFTEEN (15) DAYS PRIOR TO THE EXPIRATION DATES OF
SAID POLICY OR POLICIES, TENANT SHALL PROVIDE COPIES OF POLICIES OR
CERTIFICATES OF INSURANCE EVIDENCING COVERAGE REQUIRED BY THIS LEASE.

     (c) Landlord shall insure the Building of which the Premises are a part
and any improvements constructed by Landlord in accordance with Article 10 and
Tenant shall insure the trade fixtures, equipment (including but not limited to
all equipment, machinery, furnishings and inventory) and any tenant
improvements and/or Alterations constructed by Tenant against loss or damage by
fire and such other risks as may be included in the broadest form of extended
coverage insurance including sprinkler leakage.

     (d) Tenant shall not engage in any activity or store any product or
material in the Premises which will either cause an increase in the insurance
on the entire Building or which will make the Building uninsurable.  In the
event Tenant engages in any activity or stores any product or material in the
Premises which causes an increase in the insurance on the entire Building
(nothing contained herein being intended to authorize or permit same) Tenant
shall pay, on demand, as Additional Rent from time to time, all such increased
cost of insurance.

     (e) All Tenant's policies of insurance (and renewals) required to be
carried hereunder shall (iv) provide that no material change or cancellation of
said policies shall be made without thirty (30) days prior written notice to
Landlord; (v) provide that any loss shall be payable notwithstanding any act or
negligence of the Landlord which might otherwise result in the forfeiture of    
said insurance; and (vi) provide that as to the interest of Landlord, the
insurance afforded by the policy shall not be invalidated by any breach or
violation  by Tenant of any of the warranties, declarations or conditions in
the policy IF AVAILABLE.

     19. WAIVER OF SUBROGATION.  Tenant and Landlord respectively,  hereby
release each other from any and all liability or responsibility to the other
for anyone claiming by, through or under it or them by way of subrogation or
otherwise for any loss or damage to property covered by any insurance then in
force, even if such loss or damage shall have been caused by the fault or
negligence of the other party or anyone for whom such party may be responsible;
provided, however, that this release shall be 


                                      10
<PAGE>   15

applicable and in force and effect only with respect to any loss or damage
occurring during such time as the policy or policies of to the effect that this
release shall not adversely affect or impair such insurance or prejudice the
right of the insured to recover thereunder.  Landlord and Tenant each agree to
use their best efforts  to obtain such a waiver in all applicable insurance
policies, failing which such party shall immediately notify the other of such
inability to obtain a waiver and provide with such notice written evidence of
all attempts to procure same and the written rejection of the insurers
consulted.

     20. WAIVER OF CLAIMS.  Except as otherwise in this Lease provided,
Landlord and Landlord's agents, servants and employees shall not be liable for,
and Tenant hereby releases and relieves Landlord, its agents, servants,
employees from, all liability in connection with any and all loss of life,
personal injury, damage to or loss of property, or loss or interruption of
business occurring to Tenant, its agents, servants, employees, invitees,
licensees, visitors, or any other person, firm, corporation or entity, in or
about or arising out of the Premises, from, without limitation, (a) any fire,
other casualty, accident, occurrence or condition in or upon the Premises,
Building and/or Property; (b) any defect in or failure of (I) plumbing,
sprinkling, electrical, heating or air conditioning systems or equipment,
telecommunication conduit, lines and equipment or any other systems and
equipment of the Premises and the Building, and (ii) the elevators, stairways,
railings or walkways of the Building and/or Property; (c) any steam, gas, oil,
water, rain or snow that may leak into, issue or flow from any part of the
Premises, Building and/or Property from the drains, pipes, roof, or plumbing,
sewer or other installation of same, or from any other place or quarter; (d)
the breaking or disrepair of any installations and equipment; (e) the falling
of any fixture or any wall or ceiling materials; (f) damaged or broken interior
or exterior glass; (g) latent or patent defects; (h) the exercise of any rights
by Landlord under the terms and conditions of this Lease; (I) any acts or
omissions of the other tenants or occupants of the Building or of nearby
buildings; (J) any acts or omissions of other persons or requirements or
restrictions of governmental entities; (k) any acts or omissions of Landlord,
its agents, servants and employees with the exception of Landlord's gross
negligence or willful misconduct; and (1) theft, acts of God, public enemy,
injunction, riot, strike, insurrection, war, court order or any order of any
governmental authorities having jurisdiction over the Premises.

     21. FIRE OR OTHER CASUALTY. (a) Subject to subsections (b), (c) and (d) of
this Article 21 below, if the Premises are damaged by-fire or other casualty,
the damage shall be repaired by and at the expense of Landlord and the Rent
until such repairs shall be made shall be apportioned from the date of such
fire or other casualty according to the part of the Premises which is usable by
Tenant.  Landlord agrees to repair such damage within a reasonable period of
time after receipt from Tenant of written notice of such damage, except that
Tenant agrees to repair and replace its own furniture, furnishings, equipment
and any alteration or improvement installed by Tenant.  Landlord shall not be
liable for any inconvenience or annoyance to Tenant or injury to the business
of Tenant resulting from such damage or the repair thereof.

     (b) If the Premises, in the opinion of Landlord's licensed architect or
engineer, are (I) rendered substantially untenantable by reason of such fire or
other casualty; or (ii) twenty (20%) percent or more of the Premises is damaged
by said fire or other casualty and less than six (6) months would remain on the
Lease term or any renewal thereof upon completion of the repairs or
reconstruction; or (iii) fifty (50%) percent or more on the Premises is damaged
by said fire or other casualty; then in any such events Landlord shall have the
right to be exercised by notice in writing delivered to the Tenant within
thirty (30) days from and after said occurrence, to elect to terminate this
Lease, and, in 


                                      11
<PAGE>   16

such event, this Lease and the tenancy hereby created shall cease as of the
date of said occurrence, the Rent to be adjusted as of said date.

     (c) If the Building, in the sole opinion of Landlord, shall be
substantially damaged by fire or other casualty, regardless of whether or not
the Premises were damaged by such occurrence, Landlord shall have the right, to
be exercised by notice in writing delivered to Tenant within thirty (30) days
from and after said occurrence, to terminate this Lease; and in such event,
this Lease and the tenancy hereby created shall cease as of the date of said
termination, the Rent to be adjusted as of the date of such termination.

     (d) In the event that any mortgagee unilaterally refuses to make the
proceeds of any policy of insurance available for restoration, Landlord shall
have the right, to be exercise by notice in writing delivered to Tenant within
thirty (30) days from notice of such refusal to terminate this Lease and in
such event, this Lease and the tenancy hereby created shall cease as of the
date of said termination, the Rent to be adjusted as of the date of such
termination.

     22. CONDEMNATION.   (a) If the whole of the Premises shall be condemned or
taken either permanently or temporarily for any public or quasi-public use or
purpose, under any statute or by right of eminent domain, or by private
purchase in lieu thereof, then in that event the term of this Lease shall cease
and terminate from the date when possession is taken thereunder pursuant to
such proceeding or purchase.  The rent shall be adjusted as of the time of such
termination and any rent paid for a period thereafter shall be refunded.  In
the event more than fifteen (15%) percent of the Building containing same shall
be so taken (or if more than fifty (50%) percent of the parking areas are taken
and not promptly replaced with contiguous parking areas) then Landlord may
elect to terminate this Lease from the date when possession is taken thereunder
pursuant to such proceeding or purchase or, Landlord shall repair and restore,
at its own expense, the portion not taken and thereafter the rent shall be
reduced proportionately to the portion of the premises taken.

     (b) In the event of any total or partial taking of the Premises or the
Building, Landlord shall be entitled to receive the entire award in such
proceeding and Tenant may make a separate application for Tenant's fixtures,
equipment and moving expenses under the then applicable New Jersey eminent
domain code, but  Tenant shall not make any claim that will detract from or
diminish any award for which Landlord may make a claim.

     (c) If the Premises or the Building are declared unsafe by any duly
constituted authority having the power to make such determination, or are the
subject of a violation notice or notice requiring repair or reconstruction
which cannot be repaired by Landlord at its sole cost and expense within thirty
(30) days, then Landlord at its option, may terminate this Lease, and in such
event, Tenant shall immediately surrender said Premises to Landlord and
thereupon this Lease shall terminate and the rent shall be apportioned as of
the date of such termination.

     23. ESTOPPEL CERTIFICATE.  Tenant shall, at any time and from time to
time, within ten (10) days after written request by Landlord, execute,
acknowledge and deliver to Landlord, or its mortgagee or trustee, a statement
in writing duly executed by Tenant (I) certifying that this Lease is in full
force and effect (if that be the case) without modification or amendment (or,
if there have been any modifications or amendments, that this Lease is in full
force and effect as modified and amended and setting forth the modifications or
amendments) , (ii) certifying the dates to which Base Rent and Additional Rent
have been paid, (iii) either certifying that to the knowledge of the Tenant no
default exists  


                                      12
<PAGE>   17

under this Lease or specifying each such default, and (iv)
providing such other information as Landlords purchaser or mortgagee may
reasonably request; it being the intention and agreement of Landlord and Tenant
that any such statement by Tenant may be relied upon by a prospective purchaser
or a prospective or current mortgagee of the Building, or by others, in any
matter affecting the Premises.

     24.  TENANT'S DEFAULT.    (a)  The occurrence of any of the following
shall constitute a material default and breach of this Lease by Tenant:

         (i) failure of Tenant to accept possession of the Premises within 
thirty (30) days after the date of issuance of a certificate of occupancy;

         (ii) the vacation or abandonment of the Premises by Tenant;

         (iii)  a failure by Tenant to pay, within five (5) days after written
notice, any installment of Rent hereunder or any Additional Rent or any such
other sum herein required to be paid by Tenant;

         (iv) a failure by Tenant to observe and perform any other provisions or
covenants of this Lease to be observed or performed by Tenant, where such
failure continues for thirty (30) days after written notice thereof from
Landlord to Tenant provided, however, that if the nature of the default is such
that the same cannot reasonably be cured within such thirty (30) day period,
Tenant shall not be deemed to be in default if Tenant shall within such period
commence such cure and thereafter diligently prosecute the same to completion
(but in no event shall such cure period exceed an additional thirty (30) days).

   (b)  Upon the occurrence of any such event of default set forth above:

         (i) Landlord may (but shall not be required to) perform for the 
account of Tenant any such default of Tenant and immediately recover as
Additional Rent any expenditure made and the amount of any obligations incurred
in connection therewith, plus interest at the Rate (as defined in Article 17
hereof) from the date of such expenditure FROM DATE OF NOTICE TO TENANT;

         (ii) Landlord may at its option accelerate all Rent and Additional Rent
due for the balance of the term of this Lease and declare the same to be
immediately due and payable as liquidated damages;

         (iii) Landlord, at its option, may serve notice upon Tenant that this
Lease and the then unexpired term hereof and all renewal options shall cease
and expire and become absolutely void on the date specified in such notice, to
be not less than five (5) days after the date of such notice without any right
on the part of the Tenant to save the forfeiture by payment of any sum due or
by the performance of any terms, provision, covenant, agreement or condition
broken; and, thereupon and at the expiration of the time limit in such notice,
this Lease and the term hereof granted, as well as the right, title and
interest of the Tenant hereunder, shall wholly cease and expire and become void
in the same manner and with the same force and effect (except as to Tenant's
liability) as if the date fixed in such notice were the date herein granted for
expiration of the term of this Lease.  Thereupon, Tenant shall immediately quit
and surrender to Landlord the Premises, and Landlord may enter into and
repossess the Premises by summary proceedings, detainer, ejectment or otherwise
and remove all occupants thereof and, at Landlord's option, any property
thereon without being liable to indictment, prosecution or damages therefor.
No such expiration or termination of this Lease shall 



                                      13
<PAGE>   18

relieve Tenant of its liability and obligations under this Lease, whether or
not the Premises shall be relet;

     (iv) Landlord may, at any time after the occurrence of any event of
default, re-enter and repossess the Premises and any part thereof and attempt
in its own name, as agent for Tenant if this Lease not be terminated or in its
own behalf if this Lease be terminated, to relet all or any part of such
Premises for and upon such terms and to such persons, firms or corporations and
for such period or periods as Landlord, in its sole discretion, shall
determine, including the term beyond the termination of this Lease; and
Landlord shall not be required to accept any tenant offered by Tenant or
observe any instruction given by Tenant about such reletting.  For the purpose
of such reletting, Landlord may decorate or make repairs, changes, alterations
or additions in or to the Premises to the extent deemed by Landlord desirable
or convenient; and the cost of such decoration, repairs, changes, alterations
or additions shall be charged to and be payable by Tenant as Additional Rent
hereunder, as well as any reasonable brokerage and legal fees expended by
Landlord; and any sums collected by Landlord from any new tenant obtained on
account of the Tenant shall be credited against the balance of the Rent due
hereunder as aforesaid.  Landlord shall be entitled to recover from Tenant all
damages and losses incurred by Landlord pursuant to the laws of the state of
New Jersey and this subparagraph including, but not limited to (I) the loss of
all Rent and Additional Rent until the Premises is released and any anticipated
loss of future Rent to the end of the term of this Lease if the Rent and
Additional Rent payable by any new tenant is less than the amount which would
have been payable by Tenant until the end of the term and (ii) an amount equal
to any rental concessions received by Tenant and (iii) an amount equal to the
unamortized cost of the improvements furnished and installed by Landlord under
this Lease.

     (v) Landlord shall have the right of injunction, in the event of a breach
or threatened breach by Tenant of any of the agreements, conditions, covenants
or terms hereof, including the actual or threatened failure to vacate the
Premises at the end of the term, to restrain the same and the right
to invoke any remedy allowed by law or in equity, whether or not other
remedies, indemnity or reimbursements are herein provided.  Landlord shall have
the right of distraint upon Tenant's goods pursuant to N.J.S.A. 2A:33-1 et seq.
upon adequate notice consistent with due process.  The right and remedies given
to Landlord in this Lease are distinct, separate and cumulative remedies; and
no one of them, whether or not exercised by Landlord, shall be deemed to be in
exclusion of any of the others.

     (vi) In the event Tenant fails to vacate the Premises upon the expiration
of this or any extended term hereunder or upon termination of this Lease,
Tenant shall pay to Landlord ONE HUNDRED THIRTY-THREE PERCENT (133%) the Rent
and Additional Rent due and payable for the month in which this Lease expired
or terminated and for the two (2) subsequent months of any holdover by Tenant,
and TWO HUNDRED PERCENT (200%) the Rent and Additional Rent for any period
beyond two months, but such payment shall not preclude Landlord's right to seek
eviction of Tenant nor constitute a consent by Landlord to such holdover by
Tenant.

     (vii) In addition to all remedies provided herein or by law, Tenant shall
pay to Landlord reasonable attorneys fees and court costs incurred as a result
of such breach.

     (viii) Should Tenant fail to pay any sum required hereunder within any
applicable grace period or should Tenant fail to perform or commit any other
act which would enable Landlord to declare a default, in lieu of the
declaration of default, Landlord shall have the option to suspend, without any
liability to Tenant,  



                                      14
<PAGE>   19

any maintenance, repair or other service which it is required by the terms
of this Lease to supply until such time as Tenant has paid to Landlord the
delinquent payment or otherwise cured any event which would enable Landlord to
declare the Lease in default.

     (ix) Landlord may, but shall not be obligated to, without prejudice and in
addition to any other rights it may have in law or equity, after giving Tenant
written notice of such default and after failure by Tenant within thirty (30)
days of the receipt of such notice to correct or to undertake and diligently
pursue correction of said default(s) (which notice and/or opportunity to cure
shall not be required in case Landlord shall determine that an emergency exists
requiring prompt action), cure such default(s) on behalf of Tenant; and Tenant
shall reimburse Landlord on demand for all costs incurred by Landlord in that
regard plus interest FROM DATE OF NOTICE OF EXPENDITURE at the Rate (as defined
in Article 17 hereof) which shall be deemed Additional Rent payable hereunder.

     25. REQUIREMENT OF STRICT PERFORMANCE.  The failure or delay on the part of
either party to enforce or exercise at any time any of the provisions, rights or
remedies in the Lease shall in no way be construed to be a waiver thereof, nor
in any way to affect the validity of this Lease or any part hereof, or the right
of the party to thereafter enforce each and every such provision, right or
remedy.  No waiver of any breach of this Lease shall be held to be a waiver of
any other or subsequent breach.  The receipt by Landlord of rent at a time when
the rent is in default under this Lease shall not be construed as a waiver of
such default.  The receipt by Landlord of a lesser amount than the rent due
shall not be construed to be other than a payment on account of the rent then
due, nor shall any statement on Tenant's check or any letter accompanying
Tenant's check be deemed an accord and satisfaction, and Landlord may accept
such payment without prejudice to Landlord's right to recover the balance of the
rent due or to pursue any other remedies provided in this Lease.  No act or
thing done by Landlord or Landlord's agents or employees during the term of this
Lease shall be deemed an acceptance of a surrender of the Premises, and no
agreement to accept such a surrender shall be valid unless in writing and signed
by Landlord.

     26. RELOCATION OF TENANT.  INTENTIONALLY DELETED.

     27. SUBORDINATION RIGHTS OF MORTGAGEE. (a) This Lease shall be subject and
subordinate at all times to the lien of any mortgages now or hereafter placed
upon the Property, Premises or the Building without the necessity of any
further instrument or act  on the part of Tenant to effectuate such
subordination.  Tenant further agrees to execute and deliver upon demand such
further instrument or instruments evidencing such subordination of this Lease
to the lien of any such mortgage and such further instrument or instruments of
attornment as shall be desired by any mortgagee or proposed mortgagee or by any
other person.  Notwithstanding the foregoing, any mortgagee may at any time
subordinate its mortgage to this Lease, without Tenant's consent, by notice in
writing to Tenant, and thereupon this Lease shall be deemed prior to such
mortgage without regard to their respective dates of execution and delivery and
in that event such mortgagee shall have the same rights with respect to this
Lease as though it had been executed prior to the execution and delivery of the
mortgage.

     (b) In the event Landlord shall be or is alleged to be in default of any
of its obligations owing to Tenant under this Lease, Tenant agrees to give to
the holder of any mortgage (collectively the "Mortgagee") now or hereafter
placed upon the Premises or the Building and the Land, notice by registered
mail of any such default which Tenant shall have served upon the Landlord,
provided that prior thereto Tenant has been notified in writing (by way of
Notice of Assignment of Rents and/or Leases or otherwise) of the name and
address of any such Mortgagee.  Tenant shall not be

<PAGE>   20

entitled to exercise any right or remedy as there may be because of any default
by Landlord without having given such notice to the Mortgagee; and Tenant
further agrees that if Landlord shall fail to cure such default: (I) the
Mortgagee shall have an additional thirty (30) days (measured from the later of
the date on which the default should have been cured by Landlord or the
Mortgagee's receipt of such notice from Tenant) within which to cure such
default, provided that if such default be such that the same could not be cured
within such thirty (30) day period and the Mortgagee is diligently pursuing the
remedies necessary to effectuate the cure (including but not limited to
foreclosure proceedings if necessary to effectuate the cure) (BUT IN NO EVENT
SHALL SUCH CURE PERIOD EXCEED AN ADDITIONAL THIRTY (30) DAYS), then the
Mortgagee shall have such additional time as may be necessary for effectuating
the cure within which to cure such default; and (ii) Tenant shall not exercise
any right or remedy as there may be arising because of Landlord's default,
including but not limited to termination of this Lease as may be expressly
provided for herein or available to Tenant as a matter of law, if the Mortgagee
either has cured the default within such thirty (30) day period or, as the case
may be, has initiated the cure of same within such thirty (30) day period and is
diligently pursuing the cure of same as aforesaid (but in no event shall such
cure period exceed an additional thirty (30) days).

     (c) In the event Mortgagee acquires title to the Property, Premises or the
Building by foreclosure, deed in lieu of foreclosure or pursuant to the
exercise of any remedy provided in the mortgage held by such Mortgagee, such
Mortgagee shall not be (I) liable for any debt or omission of Landlord, (ii)
subject to any offset or deficiencies which Tenant might be entitled to assert
against Landlord, (iii) bound by any payment of Rent made by Tenant to Landlord
for more than one month in advance or (iv) bound by any agreement (other than

the Mortgagee.

debtor under Chapter 7 of the Bankruptcy Code as it may be amended, or to any
other successor statute thereto, and the Trustee or Tenant shall elect to
assume this Lease for the purpose of assigning the same or otherwise, such
election and assignment may only be made if all of the terms and conditions of
Section (b) hereof are satisfied.  If such Trustee shall fail to elect or
assume this Lease within sixty (60) days after the filing of the Petition, this
Lease shall be deemed to have been rejected.  Landlord shall be thereupon
immediately entitled to possession of the demised premises without further
obligation to Tenant or Trustee, and this Lease shall be canceled, but
Landlord's right to be compensated for damages in such liquidation proceeding
shall survive.

     (b) In the event a Petition for reorganization or adjustment of debts is
filed concerning Tenant under Chapters 11 or 13 of the Bankruptcy Code, or a
proceeding is filed under Chapter 7 of the Bankruptcy Code and is transferred
to Chapters 11 or 13, the Trustee or Tenant, as Debtor-in-Possession, must
elect to assume this Lease within seventy-five (75) days from the date of the
filing of the Petition under Chapters 11 or 13, or the Trustee or
Debtor-in-Possession shall be deemed to have rejected this Lease.  No election
by the Trustee or Debtor-in-Possession to assume this Lease, whether under
Chapters 7, 11 or 13, shall be effective unless each of the following
conditions, which Landlord and Tenant acknowledge are commercially reasonable
in the context of a bankruptcy proceeding of Tenant, have been satisfied, and
Landlord has so acknowledged in writing:

     (1)  The Trustee or the Debtor-in-Possession has cured, or has provided
          Landlord adequate assurance (as defined below) that:

          provided to Landlord adequate assurance (as defined below) that within

     (3)  The Trustee or the Debtor-in-Possession has provided Landlord with
          adequate assurance of the future performance of each of Tenant's,
          Trustee's or Debtor-in-Possession's obligations under this Lease;

              amount equal to three (3) months Base Rent and other monetary
              charges accruing under this Lease; and

         (ii) If not otherwise required by the terms of this Lease,
              the Trustee or Debtor-in-Possession shall also pay in advance on

                 Trustee or Debtor-in-Possession shall pay as Base Rent an

                 hereunder; and

         (iv) The obligations imposed upon the Trustee or Debtor-in-Possession
              shall continue with respect to Tenant or any assignee of the Lease
              after the completion of bankruptcy proceedings.

     (4)  The assumption of this Lease will not breach any provision in any

          the obligations of Tenant under this Lease; and

     (2)  The Bankruptcy court shall have entered an order segregating
          sufficient cash payable to Landlord, and/or the Trustee or

          lien and security interest and/or mortgage in property of Tenant,
          Trustee or Debtor-in-Possession, acceptable as to value and kind to
          Landlord, to secure to Landlord the obligation of the Trustee or
          Debtor-in-Possession to cure the monetary

            and/or non-monetary defaults under this Lease within the time
            periods set forth above; and

       (3)  In the event that this Lease is assumed by a Trustee
            appointed for Tenant or by Tenant as Debtor-in-Possession under the
            provisions of Section (2) hereof and thereafter Tenant is
            liquidated or files a subsequent Petition for reorganization or
            adjustment of debts under Chapters 11 or 13 of the Bankruptcy
            Code, then, and in either of such events, Landlord may, at its
            option, terminate this Lease and all rights of Tenant hereunder, by
            giving Tenant written notice of its election to so terminate, by no
            later than thirty (30) days after the occurrence of either of such
            events; and

       (4)  If the Trustee or Debtor-in-Possession has assumed the
            Lease pursuant to the terms and provisions of Section (1) or (2)
            herein, for the purposes of assigning (or elects to assign)
            Tenant's interest under this lease or the estate created thereby,
            to any other - person, such interest or estate may be so assigned
            only if Landlord shall acknowledge In writing that the intended
            assignee has provided adequate assurance as defined in this Section
            (4) of future performance of all of the terms, covenants and
            conditions of this Lease to be performed by Tenant.

            For purposes of this Section (4) , Landlord and Tenant acknowledge
            that, in the context of a Bankruptcy proceeding of Tenant, at a
            minimum "adequate assurance of future performance shall mean that
            each of the following conditions have been satisfied, and Landlord
            has so acknowledged in writing:

            (I)  The assignee has submitted a current financial
                 statement audited by a certified public accountant which shows
                 a net worth and working capital in amounts determined to be
                 sufficient by Landlord to assure the future performance by
                 such assignee of Tenant's obligations under this Lease; and

            (ii) The assignee, if requested by Landlord, shall
                 have obtained guarantees in form and substance satisfactory to
                 Landlord from one or more persons who satisfy Landlord's
                 standards of creditworthiness; and

            (iii)    Landlord has obtained all consents or waivers
                     from any third party required under any lease, mortgage,
                     financing arrangement or other agreement by which Landlord
                     is bound to permit Landlord to consent to such assignment.

       (5)  When, pursuant to the Bankruptcy Code, the Trustee or
            Debtor-in-Possession shall be obligated to pay reasonable use and
            occupancy charges for the use of the demised premises or any
            portion thereof, such charges shall not be less than the Base Rent
            as defined in this Lease and other monetary obligations of Tenant
            for the payment of Costs and Taxes.

       (6)  Neither Tenant's interest in the Lease, nor any lesser
            interest of Tenant herein, nor any estate of Tenant hereby created,
            shall pass to any trustee, receiver or assignee for the benefit of
            creditors, or any other person or entity, or otherwise by operation
            of law under the laws of any state having jurisdiction of the
            person or property of Tenant (hereinafter referred to as the "state
            law") unless Landlord shall consent to such transfer in writing.

            or any other payments from any such trustee, receiver, assignee,
            person or other entity shall be deemed to have waived, nor
            shall it waive, the need to obtain Landlords consent of Landlord's
            right to terminate this Lease for any transfer of Tenant's interest
            under this lease without such consent.

     (7)    In the event the estate of Tenant created hereby shall be

            provisions of any present or future insolvency law under state law,

Mr. Kirk Miller
Kahn, Soares and Conway
1001 Pennsylvania Avenue, NW
Suite 1350
Washington, DC  20004

Dear Kirk:

This letter is in follow-up of our telephone conversation last week and your
proposal of August 16.  Neogen Corporation would like to employ the services of
your firm to represent us in specific government relations activities under the
following agreement.

   1.  Neogen will pay to your firm an amount of $1,750 per month
       in return for 10 hours of consulting time from yourself or one of 
       the other two principals of your firm.

   2.  At times, Neogen may request services beyond the minimum monthly
       guarantee set forth above.  In such cases, you and I should have an 
       agreement in advance on the approximate additional hours required or
       some other negotiated flat fee.

   3.  Neogen's specific areas of interest and activity with your firm should
       be considered confidential, and you will not disclose those to other 
       parties unless we agree in advance.

   4.  Because of the undoubted broad base of your consulting practice, it is
       possible that you may simultaneously be consulting for other companies
       that are Neogen competitors.  Though totally within your rights, please
       advise Neogen of any competitive firms you may now be consulting with 
       or advise us in the future if you begin consulting agreements with such
       firms.

   5.  Though we believe we are beginning a long-time and fruitful
       relationship, you have agreed that if either party is not satisfied with
       the relationship, this agreement can be canceled at the end of any month.

If you believe this letter fairly summarizes our verbal agreement, please sign
one copy for our records, retaining the other.  We are assuming this agreement
will begin with the month of September if such starting time is agreeable with
you.  To

or continue loans or otherwise to extend or continue credit to the Borrower or
to accept the Borrower's guarantees of the debt of others to the Bank.  The Bank
is willing to extend or continue such credit or accept such guarantees on the
condition, among others, that this agreement be executed by the Borrower and the
Creditor and delivered to the Bank.

THEREFORE, the Borrower and the Creditor severally represent and promise to 
each other and to the Bank as follows:
1.  DEFINITIONS AND SUBORDINATION OF SUBORDINATED DEBT TO BANK DEBT.  The
    following terms have the following meanings:
   
    a. "BANK DEBT" means Liabilities to the Bank, including without limitation
       costs of collecting those Liabilities and interest accruing on those
       Liabilities after the commencement of bankruptcy or similar insolvency
       proceedings.

    b. "LIABILITIES" means all obligations and liabilities of the Borrower,
       whether direct or indirect, absolute or contingent, joint, several, or
       joint and several, secured or unsecured, due or to become due, now
       existing or later arising, in whatever amount and however evidenced,
       including, without limitation, principal and interest.

    c. "SUBORDINATED DEBT" means Liabilities to the Creditor, including without
       limitation the debt described above.

    The Subordinated Debt is subordinated in right of payment to the Bank Debt.

2.  PERMITTED PAYMENTS.  Without the prior written consent of the Bank, the
    Borrower shall not make or give, and the Creditor shall not accept, any
    payment or other thing of value on account of the Subordinated Debt, except:
    (check applicable option, if any)

    /xx/ The Borrower may pay and the Creditor may accept currently accruing
         interest on the Subordinated Debt if (a) the Borrower is not in default
         under the Bank Debt and (b) the making of the payment to the Creditor
         will not cause a default under the Bank Debt.

    / /  The Borrower may pay and the Creditor may accept scheduled payments of
         principal and interest on the Subordinated Debt as they become due if
         (a) the Borrower is not in default under the Bank Debt and (b) the
         making of the payment to the Creditor will not cause a default under 
         the Bank Debt.

    In an event, the Borrower shall not prepay and the Creditor shall not accept
    prepayment of all or any portion of the Subordinated Debt without the prior 
    written consent of the Bank.

3.  PAYMENT TO THE BANK OF PAYMENTS AND DISTRIBUTIONS ON ACCOUNT OF
    SUBORDINATED DEBT.  Except for sums received by the Creditor in accordance
    with Section 2, the Creditor shall promptly pay or otherwise deliver to the
    Bank all amounts and other things of value which the Creditor may receive
    on account of the Subordinated Debt.  Those sums and other things of value
    shall be held in trust by the Creditor for the benefit of the Bank until 
    paid or delivered to the Bank.

    In any bankruptcy, liquidation, insolvency, receivership, or similar
    proceeding, whether at law or in equity, or pursuant to state or federal
    law, the Bank shall be entitled to receive payment in full of the
    Bank Debt from payments or other distributions made on account of the Bank
    Debt and on account of the Subordinated Debt from the assets of the
    Borrower, before the Creditor is entitled to receive any payment or thing
    of value on account of the Subordinated Debt.


4.  SUBORDINATION OF LIENS.  Except for the collateral recited above the
    Borrower has not given and shall not give, and the Creditor has not
    received and shall not accept any security for  the Subordinated Debt.  The
    Creditor expressly  subordinates all of its rights in any collateral now or
    later securing the Subordinated Debt (the "Collateral") to all present and
    future rights of the Bank in any of the Collateral to secure the Bank Debt. 
    This subordination is without regard to the time or order of attachment of
    perfection of any security interest, the time or order of filing any
    financing statement, or the giving or failure to give any notice of the
    acquisition or expected acquisition of any purchase money security
    interest. The Creditor consents to the creation and continuance of all
    present and future security interest of the Bank in the Collateral to
    secure the Bank Debt and to the enforcement of those security interest,
    including the removal of the Collateral from the real property of the
    Borrower.  This subordination as to the Collateral is intended to define
    the rights and duties of the Bank and the Creditor; it is not intended that
    any third party shall benefit from it. If the effect of any provision of
    this subordination would be to give any third party a priority status to
    which that party would not otherwise be entitled, that provision shall, to
    the extent necessary to avoid that priority, be given no effect and the
    rights and priorities of the Bank and the Creditor shall be determined in
    accordance with applicable law.

5.  GRANT OF SECURITY INTEREST IN SUBORDINATED DEBT.  To secure the prompt      
    payment and performance of the Bank Debt, the Creditor grants the Bank a
    security interest in the Subordinated Debt, all instruments evidencing the
    Subordinated Debt, the Collateral, and all other rights of the Creditor
    related to the Subordinated Debt.  The Creditor shall deliver to the Bank
    all notes and other instruments evidencing any Subordinated Debt with such
    endorsements as the Bank may reasonably require.  In addition, the Creditor
    shall execute and deliver to the Bank all financing statements which the 
    Bank may reasonably require in order to perfect the Bank's rights and 
    interests under this agreement.

6.  BANK'S AUTHORITY TO ACT WITH RESPECT TO SUBORDINATED DEBT.  The Creditor
    irrevocably appoints the Bank its attorney-in-fact with full power of
    substitution, in either the Bank's name or the Creditor's name to sign      
    financing statements, endorse instruments, execute and file proofs of claim
    or other documents, and take any other action regarding all or any part of
    the Subordinated Debt necessary or appropriate to insure payment to the
    Bank of all payments and other distributions on account of the Subordinated
    Debt, instruments evidencing the Subordinated Debt, or the Collateral.
    Notwithstanding the foregoing, the Bank shall not be liable to the
    Creditor for any failure to prove the 
<PAGE>   3
     existence, amount or circumstances of the Subordinated Debt, to exercise
     any right related to it, or to collect any sums payable on it or
     distributions attributable to it.

 7.  CREDITOR'S REPRESENTATIONS AND PROMISES.  The Creditor represents to the
     Bank that (a) it is the sole holder of the Subordinated Debt with full
     power to make the subordinations and assignments in this agreement, (b) it
     has not made or permitted any assignment or transfer, as collateral or
     otherwise, of the Subordinated Debt, of any instrument evidencing the
     Subordinated Debt, or of any of the Collateral, and it shall not do so as
     long as this agreement remains in effect, (c) it has extended the
     Subordinated Debt and entered into this agreement based on its own
     independent investigation (or decision note to investigate) the financial
     condition of the Borrower, and (d) it has not and shall not rely on any
     representation or information of any nature regarding the Borrower made by
     or received from the Bank.

 8.  WAIVERS.  The Borrower and the Creditor each waive (a) notice of acceptance
     of this agreement, and (b) demand, presentment, notice of dishonor and
     protest in the collection of the Bank Debt or the Subordinated Debt.

 9.  ACTION REGARDING BANK DEBT.  Without notice to or the consent of the
     Creditor, the Bank may take or refrain from taking any action regarding the
     Bank Debt that it deems appropriate, including without limitation (a)
     amending, modifying, extending or renewing the Bank Debt or changing any
     interest rate applicable to it, (b) releasing, compromising, or settling
     any claim related to the Bank Debt, (c) forbearing or agreeing to forbear
     from enforcing any right or remedy related to the Bank Debt, including
     rights and remedies against any guarantor, surety or accommodation party of
     all or any part of the Bank Debt, or (d) substituting, releasing or
     exchanging any collateral for the Bank Debt.  The Bank shall not be
     required to perfect any security interest in any collateral securing the
     Bank Debt.

10.  CONTINUED RELIANCE.  The Bank, by accepting delivery of this agreement,
     shall be deemed to have relied upon all of its terms and conditions and
     shall be entitled to continue that reliance.  This agreement constitutes a
     continuing agreement of subordination, even though at times the Borrower
     may not be indebted to the Bank.  The Bank may continue, without notice to
     the Creditor, to lend monies, accept guarantees, extend credit, or modify,
     renew or make other financial accommodations to or for the account of the
     Borrower until the Bank sends the Creditor written notice of cancellation
     of this agreement or until the forty-fifth (45th) day following written
     acknowledgment by an officer of the Bank that the Bank has received written
     notice of revocation of this agreement from the Creditor.

11.  SUBROGATION.  So long as this agreement remains in effect, the Creditor
     shall not exercise any right of subrogation or other similar rights with
     respect to the Bank Debt.

12.  CONSTRUCTION.  The term "or" shall mean "and/or."  Each person or entity
     executing this agreement as a "Borrower" or "Creditor" is jointly and
     severally obligated with every other person and entity executing this
     agreement as a "Borrower" or Creditor" respectively.  The terms "Creditor"
     and "Borrower" refer to any or all of the persons signing in that capacity.
     Section headings and for convenience of reference only and do not affect
     the interpretation of this agreement.

13.  BINDING EFFECT; GOVERNING LAW; COUNTERPARTS.  This agreement binds the
     Borrower and the Creditor and their respective heirs, personal
     representatives, successors and assigns, and benefits the Bank, its
     successors and assigns. This agreement is governed by and construed in
     accordance with Michigan law. This agreement may be executed in any number
     of counterparts, each of which shall be deemed an original and all of which
     taken together constitute one and the same agreement.

14.  WAIVER OF JURY TRIAL.  The Borrower, the Creditor and the Bank after
     consulting or having had the opportunity to consult with counsel,
     knowingly, voluntarily and intentionally waive any right any of them may
     have to a trial by jury in any litigation based upon or arising out of this
     agreement or any related instrument or agreement, or any of the
     transactions contemplated by this agreement, or any course of conduct,
     dealing, statements (whether oral or written), or actions of any of them.
     Neither the Creditor, the Borrower, nor the Bank shall seek to consolidate
     by counterclaim or otherwise any action in which a jury trial has been
     waived with any other action in which a jury trial cannot be or has not
     been waived.  These provisions shall not be deemed to have been modified in
     any respect or relinquished by the Borrower, the Creditor, or the Bank
     except by a written instrument executed by all of them.

                           -------
- --------------------------------------------------------------------------------


FOR VALUE RECEIVED, the undersigned promise(s) to pay ON DEMAND to the order of
Comerica Bank ("Bank"), at any office of the Bank in the State of Michigan, One
Million Five Hundred Thousand and no /100--------------------------------
Dollars (U.S.) (or that portion of it advanced by the Bank and not repaid as
later provided) with interest until demand or an Event of Default, as later
defined, at a per annum rate equal to the Bank's prime rate from time to time in
effect plus 0.75% per annum and after that at a rate equal to the rate of
interest otherwise prevailing under this Note plus 3% per annum (but in no event
in excess of the maximum rate permitted by law.)  The Bank's "prime rate" is
that annual rate of interest so designated by the Bank and which is changed by
the Bank from time to time.  Interest rate changes will be effective for
interest computation purposes as and when the Bank's prime rate changes.
Interest shall be calculated on the basis of a 360-day year for the actual
number of days the principal is outstanding.  Unless sooner demanded, accrued
interest on this Note shall be payable on the 1st day of each month commencing
October 1, 1996. If the frequency of interest payments is not otherwise
specified, accrued interest on this Note shall be payable monthly on the first
day of each month, unless sooner demanded.  If any payment of principal or
interest under this Note shall be payable on a day other than a day on which the
Bank is open for business, this payment shall be extended to the next succeeding
business day and interest shall be payable at the rate specified in this Note
during this extension.  A late payment charge equal to 5% of each late payment
may be charged on any payment not received by the Bank within 10 calendar days
after the payment due date, but acceptance of payment of this charge shall not
waive any Default under this Note.

The principal amount payable under this Note shall be the sum of all advances
made by the Bank to or at the request of the undersigned, less principal
payments actually received in cash by the Bank.  The books and records of the
Bank shall be the best evidence of the principal amount and the unpaid interest
amount owing at any time under this Note and shall be conclusive absent manifest
error.  No interest shall accrue under this Note until the date of the first
advance made by the Bank; after that interest on all advances shall accrue and
be computed on the principal balance outstanding from time to time under this
Note until the same is paid in full.  At no time shall the Bank be under any
obligation to make any advances to the undersigned pursuant to this Note
(notwithstanding anything expressed or implied in this Note or elsewhere to the
contrary, including without limit if the Bank supplies the undersigned with a
borrowing formula) and the Bank, at any time and from time to time, without
notice, and in its sole discretion, may refuse to make advances to the
undersigned without incurring any liability due to this refusal and without
affecting the undersigned's liability under this Note for any and all amounts
advanced.

This Note and any other indebtedness and liabilities of any kind of the
undersigned (or any of them) to the Bank, and any and all modifications,
renewals or extensions of it, whether joint or several, contingent or absolute,
now existing or later arising, and however evidenced (collectively
"Indebtedness") are secured by and the Bank is granted a security interest in
all items deposited in any account of any of the undersigned with the Bank and
by all proceeds of these items (cash or otherwise), all account balances of any
of the undersigned from time to time with the Bank, by all property of any of
the undersigned from time to time in the possession of the Bank and by any other
collateral, rights and properties described in each and every mortgage, security
agreement, pledge, assignment and other security or collateral agreement which
has been, or will at any time(s) later be, executed by any (or all) of the
undersigned to or for the benefit of the Bank (collectively "Collateral").
Notwithstanding the above, to the extent that any portion of the Indebtedness is
a consumer loan, that portion shall not be secured by any mortgage on or other
security interest in the undersigned's principal dwelling which is not a
purchase money security interest as to that portion, unless expressly provided
to the contrary in another place.

If the undersigned (or any of them) or any guarantor under a guaranty of all or
part of the Indebtedness ("guarantor") (a) fail(s) to pay any of the
Indebtedness when due, by maturity, acceleration or otherwise, or fail(s) to pay
any Indebtedness owing on a demand basis upon demand: or (b) fail(s) to comply
with any of the terms or provisions of any agreement between the undersigned (or
any of them) or any such guarantor and the Bank; or (c) become(s) insolvent or
the subject of a voluntary or involuntary proceeding in bankruptcy, or a
reorganization, arrangement or creditor composition proceeding, (if a business
entity) cease(s) doing business as a going concern, (if a natural person) die(s)
or become(s) incompetent, (if a partnership) dissolve(s) or any general partner
of it dies, becomes incompetent or becomes the subject of a bankruptcy
proceeding or (if a corporation) is the subject of a dissolution, merger or
consolidation; or (d) if any warranty of representation made by any of the
undersigned or any guarantor in connection with this Note or any of the
Indebtedness shall be discovered to be untrue or incomplete; or (e) if there is
any termination, notice of termination, or breach of any guaranty, pledge,
collateral assignment or subordination agreement relating to all or any part of
the Indebtedness; or (f) if there is any failure by any of the undersigned or
any guarantor to pay when due any of its indebtedness (other than to the Bank)
or in the observance or performance of any term, covenant or condition in any
document evidencing, securing or relating to such indebtedness; or (g) if the
Bank deems itself insecure believing that the prospect of payment of this Note
or any of the Indebtedness is impaired or shall fear deterioration, removal or
waste of any of the Collateral; or (h) if there is filed or issued a levy or
writ of attachment or garnishment or other like judicial process upon the
undersigned (or any of them), or any guarantor or any of the Collateral,
including without limit, any accounts of the undersigned (or any of them) or any
guarantor with the Bank, then the Bank, upon the occurrence of any of these
events (each a "Default"), may at its option and without prior notice to the
undersigned (or any of them), declare any or all of the Indebtedness to be
immediately due and payable (notwithstanding any provisions contained in the
evidence of it to the contrary), sell or liquidate all or any portion of the
Collateral, set off against the Indebtedness any amounts owing by the Bank to
the undersigned (or any of them), charge interest at the default rate provided
in the document evidencing the relevant Indebtedness and exercise any one or
more of the rights and remedies granted to the Bank by any agreement with the
undersigned (or any of them) or given to it under applicable law.

The undersigned acknowledge(s) that this Note matures upon issuance, and that
the Bank, at any time, without notice, and without reason, may demand that this
Note be immediately paid in full.  The demand nature of this Note shall not be
deemed modified by reference to a Default in this Note or in any agreement to a
default by the undersigned or to the occurrence of an event of default
(collectively an "Event of Default").  For purposes of this Note, to the extent
there is reference to an Event of Default this reference is for the purpose of
permitting the Bank to accelerate Indebtedness not on a demand basis and to
receive interest at the default rate provided in the document evidencing the
relevant Indebtedness.  It is expressly agreed that the Bank may exercise its
demand rights under this Note whether or not an Event of Default has occurred.
The Bank, with or without reason and without notice, may from time to time make
demand for partial payments under this Note and these demands shall not preclude
the Bank from demanding at any time this Note be immediately paid in full.  All
payments under this Note shall be in immediately available United States funds,
without setoff or counterclaim.

If this Note is signed by two or more parties (whether by all as makers or by
one or more as an accommodation party or otherwise), the obligations and
undertakings under this Note shall be that of all and any two or more jointly
and also of each severally.  This Note shall bind the undersigned, and the
undersigned's respective heirs, personal representatives, successors and
assigns.

The undersigned waive(s) presentment, demand, protest, notice of dishonor,
notice of demand or intent to demand, notice of acceleration or intent to
accelerate, and all other notices and agree(s) that no extension or indulgence
to the undersigned (or any of them) or release, substitution or nonenforcement
of any security or release or substitution of any of the undersigned, any
guarantor or any other party, whether with or without notice, shall affect the
obligations of any of the undersigned.  The undersigned waiver(s) all defenses
or right to discharge available under Section 3-606 of the Uniform Commercial
Code and waive(s) all other suretyship defenses or right to discharge.  The
undersigned agree(s) that the Bank has the right to sell, assign, or grant
participations, or any interest, in any or all of the indebtedness, and that, in
connection with this right, but without limiting is ability to make other
disclosures to the full extent allowable, the Bank may disclose all documents
and information which the Bank now or later has relating to the undersigned or
the indebtedness.

The undersigned agree(s) to reimburse the holder or owner of this Note for any
and all costs and expenses (including without limit, court cost, legal expenses
and reasonable attorney fees, whether inside or outside counsel is used,
whether or not suit is instituted and, if suit is instituted, whether at the
trial court level, appellate level, in a bankruptcy, probate or administrative
proceeding or otherwise) incurred in collecting or attempting to collect this
note or incurred in any other matter or proceeding relating to this Note.

The undersigned acknowledge(s) and agree(s) that there are no contrary
agreements, oral or written, establishing a term of this Note and agree(s) that
the terms and conditions of this Note may not be amended, waived or modified
except in a writing signed by an officer of the Bank expressly stating that the
writing constitutes an amendment, waiver or modification of the terms of this
Note.  As used in this Note, the word "undersigned" means, individually and
collectively, each maker, accommodation party, indorser and other party signing
this Note in a similar capacity.  If any provision of this Note is
unenforceable in whole or part for any reason, the remaining provisions shall
continue to be effective.  THIS NOT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF MICHIGAN.

THE UNDERSIGNED AND THE BANK ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A
CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED.  EACH PARTY, AFTER CONSULTING
(OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR CHOICE,
KNOWINGLY AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT, WAIVES ANY RIGHT TO
TRIAL BY JURY IN THE EVENT OF LITIGATION REGARDING THE PERFORMANCE OR
ENFORCEMENT OF, OR IN ANY WAY RELATED TO, THIS NOTE OR THE INDEBTEDNESS.

and also of any successor in interest, including without limit any
debtor-in-possession or trustee in bankruptcy which succeeds to the interests
of this party or person (jointly and severally the "Borrower"), however this
indebtedness has been or may be incurred or evidenced, whether absolute or
contingent, direct or indirect, voluntary or involuntary, liquidated or
unliquidated, joint or several, and whether or not known to the undersigned at
the time of this Guaranty or at the time any future indebtedness is incurred
(the "Indebtedness").

The indebtedness guaranteed includes without limit: (a) any and all direct
indebtedness of the Borrower to the Bank, including indebtedness evidenced by
any and all promissory notes; (b) any and all obligations or liabilities of the
Borrower to the Bank arising under any guaranty where the Borrower has
guaranteed the payment of indebtedness owing to the Bank from a third party;
(c) any and all obligations or liabilities of the Borrower to the Bank arising
from applications or agreements for the issuance of letters of credit; (d) any
and all obligations or liabilities of the Borrower to the Bank arising out of 
any other agreement by the Borrower, including without limit any agreement to
indemnify the Bank for environmental liability or to clean up hazardous waste;
(e) any and all indebtedness, obligations or liabilities for which the Borrower
would otherwise be liable to the Bank were it not for the invalidity,
irregularity or unenforceability of them by reason of any bankruptcy,
insolvency or other law or order of any kind, or for any other reason,
including without limit liability for interest and attorney fees on, or in
connection with, any of the indebtedness from and after the filing by or
against the Borrower of a bankruptcy petition; (f) any and all amendments,
modifications, renewals and/or extensions of any of the above, including without
limit amendments, modifications, renewals and/or extensions which are evidenced
by new or additional instruments, documents or agreements; and (g) all costs of
collecting indebtedness, including without limit reasonable attorney fees.

The undersigned waive(s) notice of acceptance of this Guaranty and presentment,
demand, protest, notice of protest, dishonor, notice of dishonor, notice of
default, notice of intent to accelerate or demand payment of any Indebtedness
and diligence in collecting any Indebtedness, and agree(s) that the Bank may
modify the terms of any Indebtedness, compromise, extend, increase, accelerate,
renew or forbear to enforce payment of any or all Indebtedness, or permit the
Borrower to incur additional Indebtedness, all without notice to the undersigned
and without affecting in any manner the unconditional obligation of the
undersigned under this Guaranty. The undersigned further waive(s) any and all
other notices to which the undersigned might otherwise be entitled. The
undersigned acknowledge(s) and agree(s) that the liabilities created by this
Guaranty are direct and are not conditioned upon pursuit by the Bank of any
remedy the Bank may have against the Borrower or any other person or any
security. No invalidity, irregularity or unenforceability of any part or all of
the Indebtedness or any documents evidencing the same, by reason of any
bankruptcy, insolvency or other law or order of any kind or for any other
reason, and no defense or setoff available at any time to the Borrower, shall
impair, affect or be a defense or setoff to the obligations of the undersigned
under this Guaranty.

The undersigned deliver(s) this Guaranty based solely on the undersigned's
independent investigation of the financial condition of the Borrower and is 
(are) not relying on any information furnished by the Bank.  The undersigned
assume(s) full responsibility for obtaining any further information concerning
the Borrower's financial condition, the status of the Indebtedness or any other
matter which the undersigned may deem necessary or appropriate from time to
time.  The undersigned waive(s) any duty on the part of the Bank, and agree(s)
that it is not relying upon nor expecting the Bank to disclose to the
undersigned any fact now or later known by the Bank, whether relating to the
operations or condition of the Borrower, the existence, liabilities or
financial condition of any co-guarantor of the Indebtedness, the occurrence of
any default with respect to the Indebtedness, or otherwise, notwithstanding any
effect these facts may have upon the undersigned's risk under this Guaranty or
the undersigned's rights against the Borrower.  The undersigned knowingly
accept(s) the full range of risk encompassed in this Guaranty, which risk
includes without limit the possibility that the Borrower may incur indebtedness
to the Bank after the financial condition of the Borrower, or its ability to
pay its debts as they mature, has deteriorated.

The undersigned represent(s) and warrant(s) that: (a) the Bank has made no
representation to the undersigned as to the creditworthiness of the Borrower;
and (b) the undersigned has (have) established adequate means of obtaining from
the Borrower on a continuing basis financial and other information pertaining
to the Borrower's financial condition.  The undersigned agree(s) to keep
adequately informed of any facts, events or circumstances which might in any way
affect the risks of the undersigned under this Guaranty.

The undersigned grant(s) to the Bank a security interest in and the right of
setoff as to any and all property of the undersigned now or later in the
possession of the Bank.  The undersigned subordinate(s) any claim of any nature
that the undersigned now or later has (have) against the Borrower to and in
favor of all indebtedness and agree(s) not to accept payment or satisfaction of
any claim that the undersigned now or later may have against the Borrower
without the prior written consent of the Bank.  Should any payment,
distribution, security, or proceeds, be received by the undersigned upon or with
respect to any claim that the undersigned now or may later have against the
Borrower, the undersigned shall immediately deliver the same to the Bank in the
form received (except for endorsement or assignment by the undersigned where
required by the Bank) for application on the indebtedness, whether  matured or
unmatured, and until delivered the same shall be held in trust by the
undersigned as the property of the Bank. The undersigned further assign(s) to
the Bank as collateral for the obligations of the undersigned under this
Guaranty all claims of any nature that the undersigned now or later has (have)
against the Borrower with full right on the part of the Bank, in its own name or
in the name of the undersigned, to collect and enforce these claims.

The undersigned agree(s) that no security now or later held by the Bank for the
payment of any indebtedness, whether from the Borrower, any guarantor, or
otherwise, and whether in the nature of a security interest, pledge, lien,
assignment, setoff, suretyship, guaranty, indemnity, insurance or otherwise, 
shall affect in any manner the unconditional obligation of the undersigned
under this Guaranty, and the Bank, in its sole discretion, without notice to
the undersigned, may release, exchange, enforce and otherwise deal with any
security without affecting in any manner the unconditional obligation of the
undersigned under this Guaranty.  The undersigned acknowledges(s)
<PAGE>   12


and agree(s) that the Bank has no obligation to acquire or perfect any lien on
or security Interest in any asset(s), whether realty or personalty, to secure
payment of the Indebtedness, and the undersigned is (are) not relying upon any
asset(s) in which the Bank has or may have a lien or security interest for
payment of the Indebtedness.

The undersigned acknowledge(s) that the effectiveness of this Guaranty is not
conditioned on any or all of the Indebtedness being guaranteed by anyone else.

Until the Indebtedness is irrevocably paid in full, the undersigned waive(s)
any and all rights to be subrogated to the position of the Bank or to have the
benefit of any lien, security interest or other guaranty now or later held by
the Bank for the Indebtedness or to enforce any remedy which the Bank now or
later has against the Borrower or any other person.  Until the Indebtedness is
irrevocably paid in full, the undersigned shall have no right of reimbursement,
indemnity, contribution or other right of recourse to or with respect to the
Borrower or any other person.  The undersigned agree(s) to indemnify and hold
harmless the Bank from and against any and all claims, actions, damages, costs
and expenses, including without limit reasonable attorneys' fees, incurred by
the Bank in connection with the undersigned's exercise of any right of
subrogation, contribution, indemnification or recourse with respect to this
Guaranty.  The Bank has no duty to enforce or protect any rights which the
undersigned may have against the Borrower or any other person and the
undersigned assume(s) full responsibility for enforcing and protecting these
rights.

Notwithstanding any provision of the preceding paragraph or anything else in
this Guaranty to the contrary, if any of the undersigned is or becomes an
"insider" or "affiliate" (as defined in Section 101 of the Federal Bankruptcy
Code, as it may be amended) with respect to the Borrower, then that undersigned
irrevocably and absolutely waives any and all rights of subrogation,
contribution, indemnification, recourse, reimbursement and any similar rights
against the Borrower (or any other guarantor) with respect to this Guaranty,
whether such rights arise under an express or implied contract or by operation
of law.  It is the intention of the parties that the undersigned shall not be
(or be deemed to be) a "creditor" (as defined in Section 101 of the Federal
Bankruptcy Code, as it may be amended) of the Borrower (or any other guarantor)
by reason of the existence of this Guaranty in the event that the Borrower
becomes a debtor in any proceeding under the Federal Bankruptcy Code.  This
waiver is given to induce the Bank to enter into certain written contracts with
the Borrower included in the Indebtedness.  The undersigned warrant(s) and
agree(s) that none of Bank's rights, remedies or interests shall be directly or
indirectly impaired because of any of the undersigned's status as an "insider"
or "affiliate" of the Borrower, and the undersigned shall take any action, and 
shall execute any document, which the Bank may request in order to effectuate 
this warranty to the Bank.

If any Indebtedness is guaranteed by two or more guarantors, the obligation of
the undersigned shall be several and also joint, each with all and also each
with any one or more of the others, and may be enforced at the option of
the Bank against each severally, any two or more jointly, or some severally and
some jointly.  The Bank, in its sole discretion, may release any one or more of
the guarantors for any consideration which it deems adequate, and may fail or
elect not to prove a claim against the estate of any bankrupt, insolvent,
incompetent or deceased guarantor; and after that, without notice to any other
guarantor, the Bank may extend or renew any or all Indebtedness and may permit
the Borrower to incur additional Indebtedness, without affecting in any manner
the unconditional obligation of the remaining guarantor(s).  This action by the
Bank shall not, however, be deemed to affect any right to contribution which
may exist among the guarantors.

Any of the undersigned may terminate their obligation under this Guaranty as to
future Indebtedness (except as provided below) by (and only by) delivering
written notice of termination to an officer of the Bank and receiving from an
officer of the Bank written acknowledgement of delivery; provided, the
termination shall not be effective until the opening of business on the
forty-fifth (45th) day following written acknowledgement of delivery.  Any
termination shall not affect in any way the unconditional obligations of the
remaining guarantor(s), whether or not the termination is known to the
remaining guarantor(s).  Any termination shall not affect in any way the
unconditional obligations of the terminating guarantor(s) as to any
Indebtedness existing at the effective date of termination or any Indebtedness
created after that pursuant to any commitment or agreement of the Bank or any
Borrower loan with the Bank existing at the effective date of termination
(whether advances or readvances by the Bank are optional or obligatory), or any
modifications, extensions or renewals of any of this Indebtedness, whether in
whole or in part, and as to all of this Indebtedness and modifications,
extensions or renewals of it, this Guaranty shall continue effective until the
same shall have been fully paid.  The Bank has no duty to give notice of
termination by any guarantor(s) to any remaining guarantor(s).  The undersigned
shall indemnify the Bank against all claims, damages, costs and expenses,
including without limit reasonable attorney fees, incurred by the Bank in
connection with any suit, claim or action against the Bank arising out of any
modification or termination of a Borrower loan or any refusal by the Bank to 
extend additional credit in connection with the termination of this Guaranty.

Notwithstanding any prior revocation, termination, surrender or discharge of
this Guaranty (or of any lien, pledge or security interest securing this
Guaranty) in whole or part, the effectiveness of this Guaranty, and of all
liens, pledges and security interests securing this Guaranty, shall
automatically continue or be reinstated, as the case may be, in the event that
(a) any payment received or credit given by the Bank in respect of the
Indebtedness is returned, disgorged or rescinded as a preference, impermissible
setoff, fraudulent conveyance, diversion of trust funds, or otherwise under any
applicable state or federal law, including, without limitation, laws pertaining
to bankruptcy or insolvency, in which case this Guaranty, and all liens,
pledges and security interests securing this Guaranty, shall be enforceable
against the undersigned as if the returned, disgorged or rescinded payment or
credit had not been received or given by the Bank, and whether or not the Bank
relied upon this payment or credit or changed its position as a consequence of
it; or (b) any liability is imposed, or sought to be imposed, against the Bank
relating to the environmental condition of, or the presence of hazardous or
toxic substances on, in or about, any property given as collateral to the Bank
by the Borrower, whether this condition is known or unknown, now exists or
subsequently arises (excluding only conditions which arise after any
acquisition by the Bank of any such property, by foreclosure, in lieu of
foreclosure or otherwise, to the extent due to the wrongful act or omission of
the Bank), in which case this Guaranty, and all liens, pledges and security
interests securing this Guaranty, shall be enforceable against the undersigned
to the extent of all liability, costs and expenses (including without limit
reasonable attorneys' fees) incurred by the Bank as the direct or indirect
result of any environmental condition or hazardous or toxic substances.  In the
event of continuations or reinstatement of this Guaranty and the liens, pledges
and security interest securing it, the undersigned agree(s) upon demand by the
Bank to execute and deliver to the Bank those documents which the Bank
determines are appropriate to further evidence (in the public records or
otherwise) this continuation or reinstatement, although the failure of the
undersigned to do so shall not affect in any way the reinstatement or
continuation.  If the undersigned do(es) not execute and deliver to the Bank 
upon demand such documents, the Bank and each Bank officer is irrevocably
appointed (which appointment is coupled with an interest) the true and
lawful attorney of the undersigned (with full power of substitution) to execute
and deliver such documents in the name and on behalf of the undersigned.  For
purposes of this Guaranty, "environmental condition" includes, without
limitation, conditions existing with respect to the surface or ground water,
drinking water supply, land surface or subsurface and the air; and "hazardous
or toxic substances" shall include any and all substances now or subsequently
determined by any federal, state, or local authority to be hazardous or toxic,
or otherwise regulated by any of these authorities.
<PAGE>   13
Although the intent of the undersigned and the Bank is that Michigan law shall
apply to this Guaranty, regardless if Michigan law applies, the undersigned
further agree(s) as follows:  With respect to the limitation, if any, stated in
the Additional Provisions below on the amount of principal guaranteed under this
Guaranty, the undersigned agree(s) that (a) this limitation shall not be a
limitation on the amount of Borrower's Indebtedness to the Bank; (b) any
payments by the undersigned shall not reduce the maximum liability of the
undersigned under this Guaranty unless written notice to that effect is actually
received by the Bank at or prior to the time of the payment; and (c) the
liability of the undersigned to the Bank shall at all times be deemed to be the
aggregate liability of the undersigned under this Guaranty and any other
guaranties previously or subsequently given to the Bank by the undersigned and
not expressly revoked, modified or invalidated in writing.

The undersigned waive(s) any right to require the Bank to: (a) proceed against
any person, including without limit the Borrower; (b) proceed against or exhaust
any security held from the Borrower or any other person; (c) give notice of the
terms, time and place of any public or private sale of personal property
security held from the Borrower or any other person, or otherwise comply with
the provisions of Section 9-504 of the Michigan or other applicable Uniform
Commercial Code; (d) pursue any other remedy in the Bank's power; or (e) make
any presentments or demands for performance, or give any notices of
nonperformance, protests, notices of protest, or notices of dishonor in
connection with any obligations or evidences of Indebtedness held by the Bank as
security, in connection with any other obligations or evidences of indebtedness
which constitute in whole or in part Indebtedness, or in connection with the
creation of new or additional Indebtedness.

The undersigned authorize(s) the Bank, either before or after termination of
this Guaranty, without notice to or demand on the undersigned and without
affecting the undersigned's liability under this Guaranty, from time to time to:
(a) apply any security and direct the order or manner of sale of it, including
without limit, a non-judicial sale permitted by the terms of the controlling
security agreement, mortgage or deed of trust, as the Bank in its discretion may
determine; (b) release or substitute any one or more of the endorsers or any
other guarantors of the indebtedness; and (c) apply payments received by the
Bank from the Borrower to any indebtedness of the Borrower to the Bank, in such
order as the Bank shall determine in its sole discretion, whether or not this
indebtedness is covered by this Guaranty, and the undersigned waive(s) any
provision of law regarding application of payments which specifies otherwise.
The Bank may without notice assign this Guaranty in whole or in part.  Upon the
Bank's request, the undersigned agree(s) to provide to the Bank copies of the
undersigned's financial statements.

The undersigned waive(s) any defense based upon or arising by reason of (a) any
disability or other defense of the Borrower or any other person; (b) the
cessation or limitation from any cause whatsoever, other than final and
irrevocable payment in full, of the Indebtedness; (c) any lack of authority of
any officer, director, partner, agent or any other person acting or purporting
to act on behalf of the Borrower which is a corporation, partnership or other
type of entity, or any defect in the formation of the Borrower; (d) the
application by the Borrower of the Proceeds of any indebtedness for purposes
other than the purposes represented by the Borrower to the Bank or intended or
understood by the Bank or the undersigned; (e) any act or omission by the Bank
which directly or indirectly results in or aids the discharge of the Borrower or
any Indebtedness by operation of law or otherwise; or (f) any modification of
the Indebtedness, in any form whatsoever including without limit any
modification made after effective termination, and including without limit the
renewal, extension, acceleration or other change in time for payment of the
Indebtedness, or other change in the terms of any Indebtedness, including
without limit increase or decrease of the interest rate. The undersigned
waive(s) any defense the undersigned may have based upon any election of
remedies by the Bank which destroys the undersigned's subrogation rights or the
undersigned's right to proceed against the Borrower for reimbursement, including
without limit any loss of rights the undersigned may suffer by reason of any
rights, powers or remedies of the Borrower in connection with any
anti-deficiency, appraisement or valuation laws or any other laws limiting,
qualifying or discharging any Indebtedness.


The undersigned acknowledge(s) that the Bank has the right to sell, assign,
transfer, negotiate, or grant participations in all or any part of the
indebtedness and any related obligations, including without limit this Guaranty.
In connection with that right, the Bank may disclose any documents and
information which the Bank now or later acquires relating to the undersigned and
this Guaranty, whether furnished by the Borrower, the undersigned or otherwise.
The undersigned further agree(s) that the Bank may disclose these documents and
information to the Borrower.

The total obligation under this Guaranty shall be UNLIMITED unless specifically
limited in the Additional Provisions of this Guaranty, and this obligation
(whether unlimited or limited to the extent indicated in the Additional
Provisions) shall include, IN ADDITION TO any limited amount of principal
guaranteed, any and all interest on all Indebtedness and any and all costs and
expenses of any kind, including without limit reasonable attorney fees, incurred
by the Bank at any time(s) for any reason in enforcing any of the duties and
obligations of the undersigned under this Guaranty or otherwise incurred by the
Bank in any way connected with this Guaranty, the Indebtedness or any other
guaranty of the Indebtedness (including without limit reasonable attorney fees
and other expenses incurred in any suit involving the conduct of the Bank, the
Borrower or the undersigned).  All of these costs and expenses shall be payable
immediately by the undersigned when incurred by the Bank, without demand, and
until paid shall bear interest at the highest per annum rate applicable to any
of the Indebtedness, but not in excess of the maximum rate permitted by law. Any
reference in this Guaranty to attorney fees shall be deemed a reference to fees,
charges, costs and expenses of both in-house and outside counsel and paralegals,
whether or not a suit or action is instituted, and to court costs if a suit or
action is instituted, and whether attorney fees or court costs are incurred at
the trial court level, on appeal, in a bankruptcy, administrative or probate
proceeding or otherwise.  Any reference in the Additional Provisions or
elsewhere (a) to this Guaranty being secured by certain collateral shall NOT be
deemed to limit the total obligation of the undersigned under this Guaranty or
(b) to this Guaranty being limited in any respect shall NOT be deemed to limit
the total obligation of the undersigned under any prior or subsequent guaranty
given by the undersigned to the Bank.

The undersigned unconditionally and irrevocably waive(s) each and every defense
and setoff of any nature which, under principles of guaranty or otherwise, would
operate to impair or diminish in any way the obligation of the undersigned under
this Guaranty, and acknowledge(s) that each such waiver is by this reference
incorporated into each security agreement, collateral assignment, pledge and/or
other document from the undersigned now or later securing this Guaranty and/or
the Indebtedness, and acknowledge(s) that as of the date of this Guaranty no
such defense or setoff exists.  The undersigned acknowledge(s) that the
effectiveness of this Guaranty is subject to no conditions of any kind. 

This Guaranty shall remain effective with respect to successive transactions
which shall either continue the Indebtedness, increase or decrease it, or from
time to time create new Indebtedness after all or any prior Indebtedness has
been satisfied, until this Guaranty is terminated in the manner and to the
extent provided above.

The undersigned warrant(s) and agree(s) that each of the waivers set forth above
are made with the undersigned's full knowledge of their significance and
consequences, and that under the circumstances, the waivers are reasonable and
not contrary to public policy or law.  If any of these waivers are determined to
be contrary to any applicable law or public policy, these waivers shall be
effective only to the extent permitted by law.

This Guaranty constitutes the entire agreement of the undersigned and the Bank
with respect to the subject matter of this Guaranty. No waiver, consent,
modification or change of the terms of this Guaranty shall bind any of the

interests in certain properties of the undersigned, including but not limited to
accounts receivable, inventory, and machinery and equipment, all pursuant to

undersigned under this Guaranty, which obligation shall be unlimited.

THE UNDERSIGNED AND BANK ACKNOWLEDGE THAT THE RIGHT TO TRIAL BY JURY IS A
CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED. EACH PARTY, AFTER CONSULTING (OR
HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR CHOICE, KNOWINGLY
