                                     ITEM 1.

                                    BUSINESS

GENERAL

         The Company develops, manufactures and markets a diverse line of
disposable diagnostic test kits and related diagnostic products used for the
rapid diagnosis of infectious diseases. To meet market demands, the Company's
products provide accuracy, simplicity, and speed, leading to opportunities for
improvements in diagnosis and reductions in health care costs. All of the
Company's products are used in procedures performed in vitro (outside the body)
and require little or no special instrumentation or equipment.

         The Company's product development strategy is to combine existing
technologies with new product designs both through internal product development
and through product acquisitions, licensing or supply arrangements. Internal
product development activities focus on the development or enhancement of
immunodiagnostic technologies and applications to simplify, accelerate or
increase the accuracy of diagnoses of certain infectious diseases. Since 1991,
the Company has also acquired or obtained rights to distribute a number of
products and technologies.

         The Company utilizes its resources to serve each of the strategic
domestic and international medical markets it has targeted: hospital networks
and clinical and hospital laboratories; alternate site markets, including
physicians' offices, outpatient clinics, nursing homes and health maintenance
organizations (HMOs); and new markets, including veterinary laboratories, water
treatment facilities and consumer self-testing. The Company markets
approximately 100 products representing five major disease states through a
direct sales force in the U.S. and Italy, supplemented by a network of national
and international distributors. International sales in approximately 50
countries were approximately 26% of total fiscal 1996 sales, with approximately
83% of international sales originating in Western Europe. The majority of the
remaining international sales were from Canada, Mexico and the Pacific Rim.

ACQUISITION STRATEGY

         An important facet of the Company's long-term business strategy is the
acquisition, licensing or entrance into supply arrangements to obtain innovative
diagnostic testing technologies, product formats and products that complement
its existing operations and address the needs of the Company's existing and
targeted customer base. Historically, Company management has pursued the
acquisition and licensing of products and technologies that fit the Company's
niche diagnostic test markets, which are characterized by a large number of
users. Examples of this strategy include the acquisitions of the mononucleosis
and infectious disease product lines in fiscal 1993 and 1994 respectively from
Johnson & Johnson for approximately


                                      3
<PAGE>   4
$3.4 million each, the June 1996 acquisition of the enteric product line of
Cambridge Biotech Corporation for approximately $6.7 million and numerous
smaller product acquisitions and licensing arrangements. A key component in the
success of the Company's acquisition and licensing of new products and
technologies has been the ability of Company management to respond quickly to
acquisition and licensing opportunities as they arise in the marketplace. The
success of this strategy has also been due in part to management's selective
acquisition and licensing philosophy as well as availability of cash.

         June 1996 Acquisition

         On June 24, 1996, the Company acquired the enteric product line of
Cambridge Biotech Corporation. The line consists of diagnostic products which
identify Adenovirus, Rotavirus, C. difficile and Lyme disease, all of which are
enzyme immunoassay microtiter formats, similar to the Company's existing Premier
products. This line consists of the branded products Adenoclone, Rotaclone,
Cytoclone and a product for the detection of Lyme disease. Along with the
Company's Meritec and ImmunoCard products, the addition of Rotaclone and
Adenoclone makes the Company an industry leader in the pediatric diarrhea
diagnostic market. Cytoclone is the first direct test available for the
detection of the C. difficile Toxin B. The Lyme disease diagnostic test is a
complementary product offering in the Company's parasitic disease area.

         The Company paid Cambridge Biotech Corporation $6,678,000 million in
cash for the acquired enteric product line and related rights and assets, which
purchase price was allocated to: an advance on royalties of $200,000; inventory
valued at $830,000; fixed assets valued at $200,000 and intangibles valued at
$5,448,000. The Company also assumed certain royalty obligations of Cambridge
Biotech Corporation.

         The acquired products will be distributed on a direct basis throughout
the United States by the Company's own sales force and through current
distributors internationally, primarily in Germany and Japan. Approximately 65%
of the acquired products are sold in the U.S.

IMMUNODIAGNOSTICS OVERVIEW

         In vitro diagnostic testing is the process of analyzing constituents of
blood, urine, stool, other bodily fluids or tissue for the presence of specific
infectious diseases. Immunodiagnostic testing, which is the leading method of in
vitro testing for infectious diseases, tests for antigens and antibodies. When
an infectious disease caused by pathogens, such as bacteria, viruses and fungi,
and their related antigens is present, the body responds by producing an
antibody. The antibody binds specifically with the antigen in a lock-and-key
fashion and initiates a biochemical reaction to attempt to neutralize and
ultimately to eliminate the antigen. The ability of an antibody to bind with a
specific antigen provides the basis for immunodiagnostic testing.

         Immunodiagnostic testing detects the presence of specific infectious
diseases through the "visualization," such as color changes or the formation of
visible aggregates, of the biochemical reactions caused by the antigen/antibody.
Most immunodiagnostic tests utilize one of two 


                                       4
<PAGE>   5
alternative methods to determine the presence of a specific disease in a patient
specimen. In one method, the test employs the antibody to detect directly the
presence of an antigen. Alternatively, certain tests employ the antigen to
detect the presence of an antibody.

MARKET TRENDS

         The global market for infectious disease tests continues to expand as
new disease states are identified, new therapies become available and worldwide
standards of living and access to healthcare improve. More importantly, within
this market there is a continuing shift from conventional testing, which
requires highly trained personnel and lengthy turnaround times for test results,
to more technologically advanced testing which can be performed and completed in
minutes or hours by less highly trained personnel.

         Technological advances permitting accurate testing to occur outside the
traditional hospital or laboratory setting have also affected the market for
diagnostic products. These technological developments have contributed to the
emergence of alternate site markets, such as physicians' offices, outpatient
clinics, nursing homes and HMOs, as important diagnostic market segments. These
technological advances should also contribute to the development of new markets
for the Company's products, including veterinary laboratories, water treatment
facilities and consumer self-testing in the over-the-counter market.

         The increasing pressures to contain total healthcare costs have
accelerated the increased use of diagnostic testing and the market shift to
alternate sites. With rapid and accurate diagnoses of infectious diseases,
physicians can pinpoint appropriate therapies quickly, leading to faster
recovery, shorter hospital stays and less treatment expense. In addition, these
pressures have led to a major consolidation among reference laboratories and the
formation of multi-hospital alliances that have reduced the number of
institutional customers for diagnostic products and resulted in changes in
buying practices. Specifically, multi-year exclusive or primary source marketing
or distribution contracts with institutional customers have become more common,
replacing less formal distribution arrangements of shorter duration and
involving lower product volumes.

STRATEGY

         The Company continues to execute its long-term strategy consisting of
the following elements:

         -        DEVELOPING NEW PRODUCT APPLICATIONS FROM CORE TECHNOLOGIES AND
                  FORMATS. The Company employs a market-driven product
                  development strategy to adapt or enhance diagnostic testing
                  technologies and product formats in response to newly
                  identified disease states and customer demands for
                  improvements in product accuracy, simplicity, speed and
                  cost-efficiency. The Company accomplishes this by monitoring
                  existing markets, interacting closely with its customers and


                                       5
<PAGE>   6
                  recognizing emerging diseases and therapies. Since 1991, the
                  Company has developed and introduced 23 internally developed
                  products.

         -        ACQUIRING AND LICENSING PRODUCTS AND TECHNOLOGY. The Company
                  intends to acquire, license or enter into supply arrangements
                  to obtain innovative diagnostic testing technologies, product
                  formats and products that complement its existing operations
                  and address the needs of the Company's existing and targeted
                  customer base. Management regularly identifies and reviews
                  opportunities through its broad industry contacts and
                  recognized position in the industry. Since 1991, the Company
                  has acquired, licensed or entered into supply arrangements
                  relating to 33 products, five of which were acquired in June
                  1996 from Cambridge Biotech Corporation.

         -        INCREASING INTERNATIONAL SALES. The Company has targeted
                  international sales as an attractive source of growth. The
                  Company has made recent investments to develop a major
                  presence in Italy through its Italian subsidiary, Meridian
                  Diagnostics Europe s.r.l. ("MDE"), added management to expand
                  its ability to serve Latin American markets and to strengthen
                  its distribution channels into the European market. Over the
                  last four years, the Company's international sales have grown
                  from $2.1 million in fiscal 1992 to $7.8 million in fiscal
                  1996 and represented 26% of total consolidated sales in fiscal
                  1996.

         -        DEVELOPING PARTNERSHIPS WITH CONSOLIDATED HEALTHCARE
                  ORGANIZATIONS. The Company seeks to develop strategic
                  partnerships with the major reference laboratories and other
                  consolidated healthcare providers. The Company believes it is
                  in a position to develop partnerships because it is an
                  integrated manufacturer, has a broad product line, offers
                  tests in multiple formats, and is willing to invest resources
                  in building relationships and facilitating open communications
                  with those large customers. In January 1996, the Company
                  signed a three-year exclusive agreement with a major hospital
                  alliance of approximately 350 hospitals for the Company to
                  provide all parasitology transport products and specific
                  infectious disease diagnostic products. In April 1996, the
                  Company signed a three-year, primary source agreement with a
                  major reference laboratory chain consisting of over 35
                  laboratories for the supply of certain products for
                  parasitology, virology and other infectious diseases.

         -        ENTERING NEW MARKETS. The Company continues to monitor and
                  identify the emergence of new immunodiagnostic testing
                  opportunities arising from the discovery of new pathogens or
                  new linkages between existing pathogens and new diseases. In
                  April 1995, the Company introduced the first immunodiagnostic
                  test for toxigenic E. coli, a bacteria found in inadequately
                  cooked meats as well as many other food products. The Company
                  plans to apply for approvals to test both animals (United
                  States Department of Agriculture) and food products
                  (Association of Analytical Chemists) that may contain this
                  highly toxic organism. 


                                       6
<PAGE>   7
                  In September 1996, the Company began marketing its two tests
                  for the detection of E. coli bacterial toxins to U.S. food
                  testing laboratories via an exclusive distribution agreement
                  with Fisher Scientific Inc. In July 1994, the Company agreed
                  to provide its Hydrofluor product, the first product that
                  tests for water-borne parasitic pathogens, specifically
                  Giardia and Cryptosporidium, for distribution through an
                  independent supplier to water treatment facilities. The
                  Company has also entered into an agreement with Johnson &
                  Johnson to market the Company's rapid diagnostic test for
                  urinary tract infections to the consumer market, subject to
                  pre-market approval by the FDA, the timing of which cannot be
                  predicted.

         -        ACCESSING ALTERNATE SITE MARKETS FOR DIAGNOSTIC TESTING. The
                  Company seeks strong licensing/distribution partners having
                  sales and marketing strengths to enable them to promote more
                  effectively the Company's products into alternate site
                  markets. The Company believes that its products are readily
                  adaptable for use in alternate site markets. In August 1995,
                  the Company entered into an exclusive licensing agreement with
                  a third party which through its 90 representatives will
                  distribute the Company's urinary tract infection product to
                  the physician office market. The Company continues to evaluate
                  the suitability of certain of its other products for the
                  consumer market.

PRODUCTS

         The Company has expertise in the development and manufacture of
products based on multiple core diagnostic technologies, each of which enables
the visualization and identification of antigen/antibody reactions for specific
pathogens. As a result, the Company is able to develop and manufacture
diagnostic tests in a variety of formats that satisfy customer needs and
preferences, whether in a hospital, commercial or reference laboratory or
alternate site location. These technologies include enzyme immunoassay,
immunofluorescence, particle agglutination, membrane filtration/concentration,
immunodiffusion, complement fixation and chemical stains.

         ENZYME IMMUNOASSAY (EIA). Products incorporating the EIA technology
achieve extremely high levels of accuracy in detecting disease-related antigens
or antibodies through the use of special color-based enzyme-substrate reactions.
The Company utilizes this technology in its multiple test format - Premier --
for large volume users, and in its single test formats - ImmunoCard and Monolert
- -- for single physician users.

         IMMUNOFLUORESCENCE. When the microscopic visualization of an
antigen-antibody reaction is necessary or desired, immunofluorescence technology
is frequently utilized. Fluorescing immunochemicals, in the presence of the
target antigen or antibody, can be viewed via a special microscope. The Company
utilizes this technology in its Merifluor products.

         PARTICLE AGGLUTINATION. This technology utilizes microparticles (e.g.,
latex, red blood cells) coated with specific antigens or antibodies that form

MARKETING AND SALES

         The Company's marketing efforts are focused on a continual process of
seeking ways to assist healthcare providers in improving outcomes for patients
exposed to serious infectious diseases. Rapid, accurate diagnosis can mean
faster recovery, shorter hospital stays and less expense, both for the patient
and the healthcare system.

         The Company believes that its marketing goals are best served by
forming partnerships with key customers to develop concepts for future products
and technology applications. These partnerships facilitate close customer
interaction, including product strategy sessions.

         Marketing utilizes its strong industry contacts, plus key customer
focus sessions, to identify new product and other opportunities. Through the use
of cross-functional teams that include marketing, research and development and
manufacturing personnel, marketing guides the development process to meet
customers' needs with products that are easier to use, require less technical
expertise, and yield faster results--often in minutes or hours rather than days.

         Changes in the healthcare delivery system have resulted in major
consolidation among reference laboratories and the formation of multi-hospital
alliances. The Company has structured its marketing, selling and customer
service to anticipate and respond to these changes. This involved the addition
of sales and marketing personnel; the expansion of technical services staff to
support the Company's customers and distribution network through a toll-free
service hotline; and the implementation of major marketing programs to target
key customers.

         The Company markets products through direct sales forces, both
domestically and in Italy, and national and international independent
distributors. In the United States, the Company's direct sales force consists of
a director of sales, three regional sales managers, three regional product
specialists and 20 technical sales representatives. Where the Company utilizes
distributors, the Company participates in selling efforts involving key
customers. In Italy, the Company's direct sales force consists of a director of
sales, two product specialists and six technical sales representatives, as well
as an international sales manager who is responsible for all distributor
activities outside of Italy.

         The Company's sales and marketing efforts in Europe, North Africa and
the Middle East are managed through MDE's European headquarters in Milan, Italy.
MDE's strategy has been to appoint one or two distributors in each of the
countries in its targeted markets, and to maintain a direct sales organization
within Italy. The Company has approximately 50 independent distributors in
approximately 50 foreign countries. The Company has additional key distributor
relationships in Canada, Latin America and the Pacific Rim, which relationships
are managed directly from the United States.

RESEARCH AND DEVELOPMENT

         The Company's research and development activities focus on developing
new and improved diagnostic solutions. Working in conjunction with the marketing
department, the


                                       11
<PAGE>   12
Company's research and development department focuses its activities on
enhancements to and new applications for the Company's technologies. Over the
past six years Meridian has developed internally 23 new products. The research
and development department has access to a number of diagnostic technologies,
each of which can be applied to meet new product specifications that marketing
has established. The Company's product development staff are experts in binding
various biological materials to numerous solid phases, including plastics,
membranes, latex beads, immuno-fluorescent dyes and immunogold to develop
testing formats. The Company believes that its proprietary know-how and
technologies in these areas enable it to develop products that have longer
shelf-lives and provide improved performance and quicker test results.

         The research and development department initiates the Company's quality
process through its technology transfer mechanism which begins the establishment
of manufacturing standards. By working closely with the manufacturing
department, the same standards can be imposed to ensure consistently
high-quality products. The Company estimates that it takes approximately 18 to
24 months from the conceptualization of a product to its marketing.

         The research and development department includes the Vice President of
Research and Development and 15 research scientists. The disciplines represented
in the group include biochemistry, immunology, mycology, bacteriology, virology
and parasitology. In fiscal 1994, fiscal 1995 and fiscal 1996, the Company spent
$1,433,000, $1,432,000 and $1,499,000, respectively, on its research and
development activities.

CUSTOMERS

         The principal customers for the Company's products are hospitals,
commercial and reference laboratories, alternate site markets, such as
physicians' offices, outpatient clinics, nursing homes and HMOs, and new
markets, such as veterinary laboratories, water treatment facilities and
consumer self-testing. No end-use customer comprised more than 5% of the
Company's sales in fiscal 1996. Two distributors together accounted for
approximately 38% of the Company's fiscal 1996 sales. However, the Company does
not believe that the loss of either of these distributors would have a material
adverse effect on the Company because of its ability to sell to the end-use
customers served by these distributors through alternative means.

MANUFACTURING

         The Company's manufacturing is performed at its Cincinnati, Ohio
facility. All manufacturing operations are regulated by, and in compliance with,
FDA-mandated Good Manufacturing Practices for medical devices. To maintain the
highest quality standards, the Company utilizes both external and internal
quality auditors who routinely evaluate the Company's manufacturing processes.
The Company's immunodiagnostic products require the production of highly
specific and sensitive antigens and antibodies. The Company produces
substantially all of its own requirements including: monoclonal antibodies,
polyclonal antibodies, synthetic peptides, plus a variety of fungal, bacterial
and viral antigens. For the majority of its raw materials acquired from third
parties, the Company has developed dual


                                       12
<PAGE>   13
sources. As a result, the Company believes it has access to sufficient raw
materials for its products. The Company believes it has sufficient manufacturing
capacity for anticipated growth.

COMPETITION

         The market for diagnostic tests is a multi-billion dollar international
industry which is highly competitive. Many of the Company's competitors are
larger with greater financial, research, manufacturing, and marketing resources.
Important competitive factors of the Company's products include product quality,
price, ease of use, customer service and reputation. In a broader sense,
industry competition is based upon scientific and technological capability,
proprietary know-how, access to adequate capital, the ability to develop and
market products and processes, the ability to attract and retain qualified
personnel and the availability of patent protection. To the extent that the
Company's product lines do not reflect technological advances, the Company's
ability to compete in those product lines could be adversely affected.

         Companies competing in the diagnostic test industry generally focus on
a limited number of tests or limited segments of the market. As a result, the
diagnostic test industry is highly fragmented and segmented. Hundreds of
companies in the United States alone supply immunodiagnostic tests. These
companies range from multi-national healthcare companies, for which
immunodiagnostics is one line of business, to small start-up companies. Of
central importance in the industry are mid-sized medical diagnostic specialty
companies, like the Company, that offer multiple, broad product lines and have
the ability to deliver high value new products quickly to the marketplace. Among
the companies with which the Company competes in the marketing of one or more of
its products are Abbott Laboratories Inc., Becton, Dickinson and Company,
Diagnostic Products Corporation, QUIDEL Corporation and the Wampole Laboratories
Division of Carter-Wallace, Inc.

INTELLECTUAL PROPERTY, PATENTS AND LICENSES

         The Company typically does not seek patent protection for its products
and instead strives to maintain the confidentiality of its proprietary know-how.
The Company owns or licenses U.S. and foreign patents for 20 of its products.
The patents or licenses thereof for these products were acquired in connection
with the purchase of the products or the licensing of the technology on which
the products are based. In the absence of patent protection, the Company may be
vulnerable to competitors who successfully replicate the Company's production
and manufacturing techniques and processes. The Company's laboratory and
research personnel are required to execute confidentiality agreements designed
to protect the Company's proprietary products.

         The Company has no reason to believe that its products and proprietary
rights infringe the proprietary rights of any third parties. There can be no
assurance, however, that third parties will not assert infringement claims in
the future.

GOVERNMENT REGULATION

         FDA REGULATION OF MEDICAL DEVICES. The Company's products are regulated
by the Food & Drug Administration ("FDA") as "devices" pursuant to the Federal
Food, Drug and Cosmetic Act (the "FDCA"). Under the FDCA, medical devices are
classified into one of three classes (i.e., Class I, II or III). Class I and II
devices are not expressly approved by the FDA, but, instead, are "cleared" for
marketing. Class III devices generally must receive "pre-market approval" from
the FDA as to safety and effectiveness.

         A 510(k) clearance will be granted if the submitted data establishes
that the proposed device is "substantially equivalent" to an existing Class I or
Class II medical device or to a Class III medical device for which the FDA has
not required pre-market approval. The 510(k) clearance process for
"substantially equivalent" devices allows product sales to be made after the
filing of an application and upon acknowledgment by the FDA, typically within 90
to 120 days after submission. If the FDA requests additional information, the
product cannot be sold until the application has been supplemented and upon
acknowledgment by the FDA within 90 to 120 days of the supplemental application.
If there are no existing FDA-approved products or processes comparable to a
diagnostic product or process, approval by the FDA involves the more lengthy
pre-market approval procedures.

         Each of the products currently marketed by the Company has been cleared
by the FDA pursuant to the 510(k) clearance process or is exempt from such
requirements. The Company believes that most, but not all, products under
development will be classified as Class I or II medical devices and will be
eligible for 510(k) clearance. One example of a product in development that is
subject to the FDA's more lengthy pre-market approval process is the adaption of
the Company's rapid diagnostic test for urinary tract infections to the consumer
market.

         OTHER MEDICAL DEVICE REGULATION. Sales of the Company's products in
foreign countries are subject to foreign government regulation, the requirements
of which vary substantially from country to country. The time required to obtain
approval by a foreign country may be longer or shorter than that required for
FDA approval, and the requirements may differ. The Company is currently pursuing
approvals for its Premier EHEC and Premier Rotaclone products with the
Paul-Ehrlich Institute in Germany and is supporting a number of foreign product
registrations via its international distributors.

         OTHER APPROVALS. The Company intends to seek appropriate certifications
and approvals from the Association of Analytical Chemists and the United States
Department of Agriculture to enable the Company to market an immunodiagnostic
test for toxigenic E. coli in both food products and animals. The Company has no
direct experience in obtaining these certifications and approvals, but the
Company believes the time required and applicable procedures will be similar to
those required for FDA approval. However, there is no assurance that the Company
will receive these certifications and approvals.

                                LEGAL PROCEEDINGS

Meridian is a defendant in a civil action filed by Delta Biologicals, s.r.l.
("Delta") against Inova Diagnostics, Inc. ("Inova") and Meridian in the Circuit
Court of the Eleventh Judicial Circuit, Dade County, Florida, Case No. 95-12955,
in June, 1995. In July 1995, this case was removed to the United States District
Court for the Southern District of Florida, Miami Division, and assigned Case
No. 95-1604-CIV.

         In its Complaint, Delta, an Italian corporation, alleges that it has a 
contract with Inova which grants it an exclusive right to import, market and
sell products manufactured by Inova in Italy, Spain, France and Portugal and
that Inova has breached that contract by entering into a contract with, and
selling products to, Meridian, which, through its subsidiary Meridian
Diagnostics Europe, s.r.l. ("MDE"), is selling some of these same products in
Italy in violation of Delta's claimed exclusive rights. Delta further alleges
that Meridian deliberately and knowingly tortiously interfered in the
contractual relationship between Delta and Inova.

         Delta seeks judgment against Meridian of compensatory and punitive
damages in unspecified amounts in excess of $15,000. Since the filing of the
initial complaint, MDE has also been named as a defendant. The allegations and
prayer for damages against MDE are the same as those alleged against Meridian.
Defendants Inova, Meridian and MDE have filed answers denying any liabilities to
Delta, and Inova has filed a counterclaim against Delta seeking a variety of
damages totaling in excess of $400,000.

         Meridian and MDE have an agreement with Inova which obligates Inova to 
defend and indemnify them against Delta's claims up to a limit of $300,000.
Discovery is at a very early stage and, therefore, management is not able to
opine on the merits or possible outcome of this litigation. Nevertheless, based
upon management's knowledge and the opinion of outside counsel, management
believes that both Meridian and MDE have meritorious defenses and that Inova is
obligated to defend and indemnify them. Accordingly, management believes that
the ultimate resolution of the pending litigation will not have a material
adverse effect on Meridian's financial condition, results of operations or cash
flows.

         Management is not aware of any other pending or threatened litigation,
claims or assessments, asserted or unasserted, against Meridian.

dividend payments.

         The Company follows a cash dividend policy consisting of regular
quarterly dividends and special year-end dividends. The Board has set a targeted

dividends with any balance being paid as a year-end special dividend. All or a
portion of the year-end dividend may be paid in stock. The declaration and
amount of dividends are determined by the Board of Directors in its discretion
based upon its evaluation of earnings, cash flow requirements and future
business developments. There is no assurance that dividends will continue.

         On January 25, 1996, the Company increased its quarterly dividend rate
from $0.0267 to $0.035 per share. The Company paid a dividend of $0.035 per
share for each quarter of fiscal 1996. On November 18, 1996, the Company paid a
special fiscal 1996 year-end dividend of $0.025 per share payable December 6,

the Board approved an increase in the regular quarterly dividend rate from
$0.035 to $0.0425 per share.

1995. In addition, the Company paid a three-for-two stock split on October 2,

dividend of $0.025 per share.

We have audited in accordance with generally accepted auditing standards, the
consolidated financial statements included in Meridian Diagnostics, Inc. and
subsidiaries' annual report to shareholders incorporated by reference in this

the Company's management and is presented for purposes of complying with the

procedures applied in the audit of the basic financial statements and, in our
opinion, fairly states in all material respects the financial data required to
be set forth therein in relation to the basic financial statements taken as a
whole.

                                STOCK OPTION PLAN


                                     ARTICLE

                                   OBJECTIVES

                  Meridian Diagnostics, Inc. ("Meridian") has established this
Stock Option Plan effective November 14, 1995 as an incentive to the attraction
and retention of dedicated and loyal employees of outstanding ability, to
stimulate the efforts of such persons in meeting the Company's objectives and to
encourage ownership of the Company's Common Stock by employees.


                                    ARTICLE 2

                                   DEFINITIONS

         2.1 For purposes of the Plan the following terms shall have the
definition which is attributed to them, unless another definition is clearly
indicated by a particular usage and context.

                  A. "Code" means the Internal Revenue Code of 1986.

                  B. The "Company" means Meridian and any subsidiary of
         Meridian, as the term "subsidiary" is defined in Section 424(f) of the
         Code.

                  C. "Date of Exercise" means the date on which the Company has
         received a written notice of exercise of an Option, in such form as is
         acceptable to the Committee, and full payment of the purchase price.

                  D. "Date of Grant" means the date on which the Committee makes
         an award of an Option.

                  E. "Eligible Employee" means any individual who performs

         income tax purposes.

                  F. "Fair Market Value" means the last sale price reported on
         any stock exchange or over-the-counter trading system on which Shares
         are trading on the last trading day prior to a specified date or, if no
         last sales price is reported, the average of the closing bid and asked
         prices for a Share on a specified date. If no sale has been made on the
         specified date, then prices on the last preceding day on which any such
         sale shall have been made shall be used in determining Fair Market
         Value under either method prescribed in the previous sentence.

                  G. "Incentive Stock Option" shall have the same meaning as
         given to that term by Section 422 of the Code.
<PAGE>   2

                  H. "Nonqualified Stock Option" means any Option granted under
         the Plan which is not considered an Incentive Stock Option.

                  I. "Option" means the right to purchase a stated number of
         Shares at a specified price. The option may be granted to an Eligible
         Employee subject to the terms of this Plan, and such other conditions
         and restrictions as the Committee deems appropriate. Each Option shall
         be designated by the Committee to be either an Incentive Stock Option
         or a Nonqualified Stock Option.

                  J. "Option Price" means the purchase price per Share subject
         to an Option and shall be fixed by the Committee, but shall not be less
         than 100% of the Fair Market Value of a Share on the Date of Grant in
         the case of an Incentive Stock Option.

                  K. "Permanent and Total Disability" shall mean any medically
         determinable physical or mental impairment rendering an individual
         unable to engage in any substantial gainful activity, which disability
         can be expected to result in death or which has lasted or can be
         expected to last for a continuous period of not less than 12 months.

                  L. "Plan" means this 1996 Stock Option Plan as it may be
         amended from time to time.

         of the Company.

                                    ARTICLE 3

                                 ADMINISTRATION

         3.1 The Plan shall be administered by a committee (the "Committee")
designated by the Board of Directors of the Company. The Committee shall be
comprised solely of three or more directors each of whom shall be (i) a
"disinterested person" as defined under Rule 16b-3 of the Securities and
Exchange Act of 1934 (the "Act") and (ii) an "outside director" to the extent
required by Section 162(m) of the Internal Revenue Code ("Section 162(m)").
Notwithstanding the foregoing, to the extent relevant state law now or hereafter
permits, the Committee may be comprised solely of two or more such directors.

         Actions shall be taken by a majority of the Committee.

         3.2 Except as specifically limited by the provisions of the Plan, the
Committee in its discretion shall have the authority to:

                  A. Determine which Eligible Employees shall be granted
         Options;

                  B. Determine the number of Shares which may be subject to each
         Option;

                  C. Determine the Option Price;

                  D. Determine the term of each Option;
<PAGE>   3
                  E. Determine whether each Option is an Incentive Stock Option
         or Nonqualified Stock Option;

                  F. Interpret the provisions of the Plan and decide all
         questions of fact arising in its application; and

                  G. Prescribe such rules and procedures for Plan administration
         as from time to time it may deem advisable.

         3.3 Any action, decision, interpretation or determination by the
Committee with respect to the application or administration of this Plan shall
be final and binding upon all persons, and need not be uniform with respect to
its determination of recipients, amount, timing, form, terms or provisions of
Options.

         3.4 No member of the Committee shall be liable for any action or
determination taken or made in good faith with respect to the Plan or any Option
granted hereunder, and to the extent permitted by law, all members shall be
indemnified by the Company for any liability and expenses which may occur
through any claim or cause of action.

                                    ARTICLE 4

                             SHARES SUBJECT TO PLAN

         4.1 The Shares that may be made subject to Options granted under the
Plan shall not exceed 200,000 Shares in the aggregate. Except as provided in
Section 4.2, upon lapse or termination of any Option for any reason without
being completely exercised, the Shares which were subject to such Option may
again be subject to other Options.

         4.2 The maximum number of Shares with respect to which options may be
granted to any employee during each fiscal year of the Company is 50,000 Shares.
If an Option is canceled, it continues to be counted against the maximum number
of Shares for which Options may be granted to an employee. If an Option is
repriced, the transaction is treated as a cancellation of the Option and a grant
of a new Option.

                                    ARTICLE 5

                               GRANTING OF OPTIONS

         Subject to the terms and conditions of the Plan, the Committee may,
from time to time prior to November 14, 2005, grant Options to Eligible
Employees on such terms and conditions as the Committee may determine. More than
one Option may be granted to the same Eligible Employee.


                                    ARTICLE 6

                                TERMS OF OPTIONS

         6.1 Subject to specific provisions relating to Incentive Stock Options
set forth in Article 9, each Option shall be for a term of from one to ten years
from the Date of Grant and may not be exercised during the first twelve months
of the term of said Option. Commencing on the first anniversary of the Date of
Grant of an Option, the Option may be exercised for 25% of the total Shares
covered by the Option with an additional 
<PAGE>   4
25% of the total Shares covered by the Option becoming exercisable on each
succeeding anniversary until the Option is exercisable to its full extent. This
right of exercise shall be cumulative and shall be exercisable in whole or in
part. The Committee in its sole discretion may permit particular holders of
Options to exercise an Option to a greater extent than provided herein. The
Committee may establish a different exercise schedule and impose other
conditions upon exercise for any particular Option or groups of Options.

         6.2 The holder of an Option must remain continuously in the service of
the Company as an employee for a period of at least twelve months. Nothing
contained in this Plan or in any Option granted pursuant to it shall confer upon
any employee any right to continue in the employ of the Company or to interfere
in any way with the right of the Company to terminate employment at any time. So
long as a holder of an Option shall continue to be an employee of the Company,
the Option shall not be affected by any change of the employee's duties or
position.

                                    ARTICLE 7

                               EXERCISE OF OPTIONS

         Any person entitled to exercise an Option in whole or in part, may do
so by delivering a written notice of exercise to the Company, attention
Corporate Secretary, at its principal office. The written notice shall specify
the number of Shares for which an Option is being exercised and the grant date
of the option being exercised and shall be accompanied by full payment of the
Option Price for the Shares being purchased.

                                    ARTICLE 8

                             PAYMENT OF OPTION PRICE

         8.1 Payment of the Option Price may be made in cash, by the tender of
Shares, or both. Shares tendered shall be valued at their Fair Market Value on
the date of tender.

         8.2 Payment through tender of Shares may be made by instruction from
the Optionee to the Company to withhold from the Shares issuable upon exercise
that number which have a Fair Market Value on the date of tender equal to the
exercise price for the Option or portion thereof being exercised.

                                    ARTICLE 9

             INCENTIVE STOCK OPTIONS AND NONQUALIFIED STOCK OPTIONS

         9.1 The Committee in its discretion may designate whether an Option is
to be considered an Incentive Stock Option or a Nonqualified Stock Option. The
Committee may grant both an Incentive Stock Option and a Nonqualified Stock
Option to the same individual. However, where both an Incentive Stock Option and
a Nonqualified Stock Option are awarded at one time, such Options shall be
deemed to have been awarded in separate grants, shall be clearly identified, and
in no event will the exercise of one such Option affect the right to exercise
the other such Option.

         9.2 Any option designated by the Committee as an Incentive Stock Option
will be subject to the general provisions applicable to all Options granted
under the Plan. In addition, the Incentive Stock Option shall be subject to the
following specific provisions:
<PAGE>   5
                  A. At the time the Incentive Stock Option is granted, if the
         Eligible Employee owns, directly or indirectly, stock representing more
         than 10% of (i) the total combined voting power of all classes of stock
         of the Company, or (ii) a corporation that owns 50% or more of the
         total combined voting power of all classes of stock of the Company,
         then:

                           (i) The Option Price must equal at least 110% of the
                  Fair Market Value on the Date of Grant; and

                           (ii) The term of the Option shall not be greater than
                  five years from the Date of Grant.

                  B. The aggregate Fair Market Value of Shares (determined at
         the Date of Grant) with respect to which Incentive Stock Options are
         exercisable by an Eligible Employee for the first time during any
         calendar year under this Plan or any other plan maintained by the
         Company shall not exceed $100,000.

         9.3 If any Option is not granted, exercised, or held pursuant to the
provisions noted immediately above, it will be considered to be a Nonqualified
Stock Option to the extent that the grant is in conflict with these
restrictions.

                                   ARTICLE 10

                            TRANSFERABILITY OF OPTION

         During the lifetime of an Eligible Employee to whom an Option has been
granted, such Option is not transferable voluntarily or by operation of law and
may be exercised only by such individual. Upon the death of an Eligible Employee
to whom an Option has been granted, the Option may be transferred to the
beneficiaries or heirs of the holder of the Option by will or by the laws of
descent and distribution.

                             TERMINATION OF OPTIONS

         11.1     An Option will terminate as follows:

                  A.       Upon exercise or expiration by its terms.

                  B. Except as provided in Subsection 11.1.C, upon termination
         of employment for reasons other than cause, the then-exercisable
         portion of any Option will terminate on the 60th day after the date of
         termination. The portion not then exercisable will terminate on the
         date of termination of employment. For purposes of the Plan, a leave of
         absence approved by the Company shall not be deemed to be termination
         of employment.

                  C. If an Eligible Employee holding an Option dies or becomes
         subject to a Permanent and Total Disability while employed by the
         Company, or within 60 days after termination of employment, for reasons
         other than cause, such Option may be exercised, to the extent
         exercisable on the date of death, Permanent and Total Disability or
         termination of employment, at any time within one year after the date
         the employment of such Eligible 
<PAGE>   6
         Employee terminated, by the estate or guardian of such person or by
         those persons to whom the Option may have been transferred by will or
         by the laws of descent and distribution.

                  D. Options shall terminate immediately if employment is
         terminated for cause. Cause is defined as including, but not limited
         to, theft of or intentional damage to Company property, intentional
         harm to the Company's reputation, material breach of the optionee's
         duty of fidelity to the Company, the use of illegal drugs, the
         commission of a criminal act, willful violation of Company policy, or
         trading in securities of the Company for personal gain based on
         knowledge of the Company's activities or results when such information
         is not available to the general public.

                  E. If an Eligible Employee holding an Option violates any
         terms of any written employment or noncompetition agreement between the
         Company and the Eligible Employee, all existing options held by such
         Employee will terminate. In addition, if at the time of such violation
         the Employee has exercised Options but has not received certificates
         for the shares to be issued, the Company may void the Option and its
         exercise. Any such actions by the Company shall be in addition to any
         other rights or remedies available to the Company in such
         circumstances.

         11.2 Except as provided in Article 12 hereof, in no event will the
continuation of the term of an Option beyond the date of termination of
employment allow the Eligible Employee, or his beneficiaries or heirs, to accrue
additional rights under the Plan, or to purchase more Shares through the
exercise of an Option than could have been purchased on the day that employment
was terminated. In addition, notwithstanding anything contained herein, no
option may be exercised in any event after the expiration of ten years from the
date of grant of such option.

                                   ARTICLE 12

                     ADJUSTMENTS TO SHARES AND OPTION PRICE

         12.1 In the event of changes in the outstanding Common Stock of the
Company as a result of stock dividends, splitups, recapitalizations,
combinations of Shares or exchanges of Shares, the number and class of Shares
for all purposes covered by the Plan and number and class of Shares and price
per Share for each Option and each outstanding Option covered by the Plan shall
be correspondingly adjusted by the Committee.

         12.2 The Committee shall make appropriate adjustments in the Option
Price to reflect any spin-off of assets, extraordinary dividends or other
distributions to shareholders.

         12.3 In the event of the dissolution or liquidation of the Company or
any merger, consolidation, exchange or other transaction in which the Company is
not the surviving corporation or in which the outstanding Shares of the Company
are converted into cash, other securities or other property, each outstanding
Option shall terminate as of a date fixed by the Committee provided that not
less than 20 days' written notice of the date of expiration shall be given to
each holder of an Option and each such holder shall have the right during such
period following notice to exercise the Option as to all or any part of the
Shares for which it is exercisable at the time of such notice. The Committee, in
its sole discretion, may provide that Options in such circumstances may be
exercised to an extent greater than the number of shares for which they were
exercisable at the time of such a notice.
<PAGE>   7
         12.4 All outstanding Options shall become immediately exercisable in
full if a change in control of the Company occurs. For purposes of this
Agreement, a "change in control of the Company" shall be deemed to have occurred
if (a) any "person," as such term is used in Sections 13(d) and 14(d) of the
Act, other than a trustee or other fiduciary holding securities under an
employee benefit plan of the Company becomes the "beneficial owner," as defined
in Rule 13d-3 under the Act, directly or indirectly, of securities of the
Company representing 30% or more of the combined voting power of the Company's
then outstanding securities; or (b) during any period of one year (not including
any period prior to the execution of this Agreement), individuals who at the
beginning of such period constitute the Board of Directors and any new director
whose election by the Board or nomination for election by the Company's
shareholders was approved by a vote of at least two-thirds (2/3) of the
Directors then still in office who either were Directors at the beginning of the
period or whose election or nomination for election was previously so approved,
cease for any reason to constitute a majority thereof.

                                   ARTICLE 13

                                OPTION AGREEMENTS

         13.1 All Options granted under the Plan shall be evidenced by a written
agreement in such form or forms as the Committee in its sole discretion may
determine.

         13.2 Each optionee, by acceptance of an Option under this Plan, shall
be deemed to have consented to be bound, on the optionee's own behalf and on
behalf of the optionee's heirs, assigns and legal representatives, by all terms
and conditions of this Plan.

                                   ARTICLE 14

                       AMENDMENT OR DISCONTINUANCE OF PLAN

         14.1 The Board of Directors of the Company may at any time amend,
suspend, or discontinue the Plan; provided, however, that no amendments by the
Board of Directors of the Company shall, without further approval of the
shareholders of the Company:

                  A. Change the definition of Eligible Employees;

                  B. Except as provided in Articles 4 and 12 hereof, increase
         the number of Shares which may be subject to Options granted under the
         Plan.

                  C. Cause the Plan or any Option granted under the Plan to fail
         to (i) be excluded from the $1 million deduction limitation imposed by
         Section 162(m) of the Code, or (ii) qualify as an "Incentive Stock
         Option" as defined by Section 422 of the Code.

         14.2 No amendment or discontinuance of the Plan shall alter or impair
any Option granted under the Plan without the consent of the holder thereof.

                                   ARTICLE 15

                                 EFFECTIVE DATE

         This Plan shall become effective as of November 14, 1995, having been
adopted by the Board of Directors of the Company on such date subject to
approval by the affirmative vote of the holders of a majority of the shares of
Capital Stock of the Company voting on the issue, and all Options granted prior
to such approval are expressly conditioned upon such approval being received. If
shareholder approval is not received, within 12 months of the effective date,
Options granted pursuant to this Plan shall be null and void.

                                   ARTICLE 16

                                  MISCELLANEOUS

         16.1 Nothing contained in this Plan or in any action taken by the Board
of Directors or shareholders of the Company shall constitute the granting of an
Option. An Option shall be granted only at such time as a written Option shall
have been executed and delivered to the respective employee and the employee
shall have executed an agreement respecting the Option in conformance with the
provisions of the Plan.

         16.2 Certificates for Shares purchased through exercise of Options will
be issued in regular course after exercise of the Option and payment therefor as
called for by the terms of the Option but in no event shall the Company be
obligated to issue certificates more often than once each quarter of each fiscal
year. No persons holding an Option or entitled to exercise an Option granted
under this Plan shall have any rights or privileges of a shareholder of the
Company with respect to any Shares issuable upon exercise of such Option until
certificates representing such Shares shall have been issued and delivered. No
Shares shall be issued and delivered upon exercise of an Option unless and until
the Company, in the opinion of its counsel, has complied with all applicable
registration requirements of the Securities Act of 1933 and any applicable state
securities laws and with any applicable listing requirements of any national
securities exchange on which the Company securities may then be listed as well
as any other requirements of law.

         16.3 This Plan shall continue in effect until the expiration of all
Options granted under the Plan unless terminated earlier in accordance with
Article 14; provided, however, that it shall otherwise terminate ten years after
the Effective Date.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

FISCAL 1996 COMPARED TO FISCAL 1995

         Net sales increased $4,281,000 or 17%, to $29,391,000 in fiscal 1996.
This increase stems primarily from strong unit volume growth in the Premier,
Para-Pak and ImmunoCard lines coupled with the acquisition of the enteric
product line from Cambridge Biotech Corporation on June 24, 1996. In the Premier
and ImmunoCard formats, this growth continues to be attributable to those
products used for identification of Toxin A, H. pylori, EHEC, Mycoplasma and
Rotavirus. In Para-Pak, the growth is attributable to the core parasitology
transport format, Para-Pak Ultra introduced last fall and Para-Pak Plus. In
addition, the Inova line of products, licensed for Italy last year, added over
$472,000 of sales volume for the year. The products acquired from Cambridge at
the end of the third quarter contributed $1,096,000 of sales in fiscal 1996.

         OEM sales, consisting of products sold primarily to Johnson & Johnson,
Carter-Wallace, Inc. and Becton, Dickinson and Company, were down for the twelve
months ended September 30, 1996 by $190,000, largely a result of the timing of
orders of Epstein-Barr Virus products from Johnson & Johnson and declining sales
of strep latex to Becton, Dickinson and Company. This decline was partially
offset by increased sales of mononucleosis latex and FiltraCheck-UTI(R) to
Carter Wallace, Inc. and to Biostar, respectively.

         Other decreases for fiscal 1996 included the mononucleosis line, down
about 8% due to the wind-down of production of the MONOSPOT(R) product
previously supplied by ODSI, and the transition to the Company- produced, new
mononucleosis latex products; decreased chlamydia sales; and the impact of a
one-time sale of bulk giardia and cryptosporidium in Germany in fiscal 1995.

         Following is a summary of the increase in sales broken down by volume,
price and currency:

         European sales increased from $5,101,000 to $6,456,000, or 27%, for the
twelve month period principally from volume growth in the Premier line, the
Inova line licensed for Italy in fiscal 1995, ImmunoCard and Para-Pak formats.
Currency contributed $263,000, or about 5% of the growth, as a result of the
stronger lira versus the dollar.

         Gross profit increased $3,323,000, or 19%, to $20,424,000 for fiscal
1996 from $17,101,000 in fiscal 1995. As a percentage of sales, gross profit
increased to 69.5% in fiscal 1996 from 68.1% in fiscal 1995. This improvement is
the result of a favorable product mix, driven largely by growth in excess of 35%
in the ImmunoCard line, the decrease in lower margin OEM sales, favorable
year-end inventory variances, the impact of the 15% increase in volume and
significant reductions in scrap and depreciation expenses. This improvement is
particularly noteworthy considering the higher costs associated with the enteric
product line acquisition from Cambridge. In addition to the amortization of
certain acquisition costs, the acquisition includes a one-year inventory
purchase agreement at a negotiated cost expected to be higher than the Company's
cost of manufacturing when the purchased product line is fully integrated into
the Company's manufacturing facilities in Cincinnati during the third fiscal
quarter of fiscal 1997. The gross profit percentage for fiscal 1997 is expected
to decline modestly because of these higher Cambridge-related costs.

         Total operating expenses increased $1,384,000 or 13% for the twelve
months ended September 30, 1996, compared to the prior year. Total operating
expenses were 40.5% of net sales for fiscal 1996, down 1.4 percentage points
from the prior year. Research and development expenses increased $67,000 or 5%
for the twelve month period. Higher personnel costs associated with initial
development work on the Premier EHEC in food and agricultural applications plus
development of the H. pylori antigen in stool were offset in part by lower
clinical trial and contract research expenses. Selling and marketing expenses
increased $762,000 or 15% for the twelve months. Increases were attributable to
personnel costs in the U.S. associated with the addition of a third sales
region, amortization of certain Cambridge acquisition costs and higher
depreciation expense associated with the new U.S. headquarters and refurbished
facilities in Cincinnati. In Europe, expenses were up primarily from the impact
of the stronger lira versus the dollar. General and administrative expenses
increased $556,000 or 14% for the twelve month period. Personnel costs in the
U.S. and in Europe, outside


                                       10
<PAGE>   5
services associated with expanded computer information systems, facility
expenses related to the new administrative headquarters, the impact of exchange
rates from the stronger lira, higher international travel and the one-time state
filing fee for the increase in the number of authorized shares of common stock
are the primary reasons for the increase.

         Operating income, as a result of the above, increased $1,938,000 or 29%
compared to the sales increase of 17% for the 1996 twelve month period versus
last year. As a percent of sales, operating income improved almost three
percentage points to 29.0% for fiscal 1996 versus 26.2% for fiscal 1995.

         Other income (net) increased $995,000 for the period ended September
30, 1996. Interest expense (net) declined $689,000 for the twelve month period
primarily due to the reduction in interest expense as a result of the November
30, 1995 conversion of the 7 1/4% Convertible Subordinated Debentures issued by
the Company in 1993. Interest expense will increase in fiscal 1997 from the
issuance of $20 million of 7% Convertible Subordinated Debentures on September
27, 1996. Also included in the twelve month period was a gain of $150,000 from
payment of a fully reserved note related to a March 1994 Agreement, wherein the
Company sold to VAI Diagnostics, Inc. tissue culture products acquired in
January 1994 from an affiliate of ODSI, and a gain of $100,000 from the sale of
the Meritec(TM) Campy product to Integrated Diagnostics, Inc. Gains/losses in
foreign exchange for the twelve month period were not material. The cumulative
foreign currency translation adjustment increased by $98,000 during the twelve
month period as a result of the Lira strengthening against the U.S. dollar.

         The Company's effective tax rate decreased for the year to 40.5% in
fiscal 1996 compared to 40.9% in fiscal 1995.

         Net earnings increased $1,768,000, or 50% to $5,292,000 for the twelve
months ended September 30, 1996 compared to $3,524,000 in the prior year, and
improved 4 percentage points to 18.0% of sales in fiscal 1996 versus 14.0% in
fiscal 1995. The corresponding increase in primary earnings per share from $.29
in fiscal 1995 to $.36 in fiscal 1996 is approximately 24%. The lower growth
rate in earnings per share results from the increase in outstanding shares in
fiscal 1996 associated with the first quarter conversion of the 7 1/4%
convertible subordinated debentures issued by the Company in 1993 plus the
effect of outstanding stock options which is greater than 3%.

FISCAL 1995 COMPARED TO FISCAL 1994

         Net sales increased $3,233,000, or 15%, to $25,110,000 in fiscal 1995
from $21,877,000 in fiscal 1994. This increase was primarily from unit volume
growth in the Premier, ImmunoCard, Merifluor(R) and mononucleosis lines plus OEM
sales of Epstein-Barr Virus. The major growth areas are in those tests used for
identification of infectious diseases such as C. difficile, Toxin A,
mononucleosis, Mycoplasma and Herpes simplex virus. Of the increase of
$3,233,000, $1,112,000, or 34%, was attributable to the full year sales of the
infectious disease product line acquired in January 1994 from an affiliate of
ODSI.

         The increase in sales of $3,233,000 was more than accounted for by
volume of $3,271,000, or 15%, offset marginally by price decreases of $38,000
with no impact from currency translation. European sales increased $1,175,000,
or 30%, to $5,102,000 from $3,927,000 as a result of continued strong unit
growth in the Premier line, up 45% (Toxin A, H. pylori and EHEC -- introduced
during the second quarter); the mononucleosis line, up 21%; ImmunoCard, which
almost tripled largely from new products (Mycoplasma, mononucleosis, Rotavirus
and H. pylori); and Merifluor, up 81%. The increase in net sales was accounted
for by volume, $951,000, or 24%, and price, $223,000, or 6%. The effect of
currency translations was negligible.
<PAGE>   6
         Gross profit increased $2,742,000, 19%, to $17,101,000 for fiscal 1995
from $14,359,000 in fiscal 1994. As a percentage of sales, gross profit
increased to 68.1% in fiscal 1995 from 65.6% in fiscal 1994. This improvement
was due primarily to the transfer and in-house manufacture of the product lines
acquired from ODSI in June 1993 and January 1994, which prior to October 1994
were purchased under a supply agreement with ODSI. Fiscal 1994 costs also
included integration of the ODSI infectious disease product line into Meridian's
manufacturing facilities in Cincinnati. Other factors contributing to the
improvement included continued favorable efficiency and volume variances from
the sales increase, the new warehouse facilities, and the reduction in factory
overhead including decreased rent expense from the new on-site warehouse, lower
insurance and employee benefit expense, plus a reduction in travel.

         Operating expenses increased $980,000, or 10%, to $10,525,000 for
fiscal 1995 from $9,545,000 in fiscal 1994, but declined as a percentage of
sales from 43.6% in fiscal 1994 to 41.9% in fiscal 1995. Research and
development expenses were marginally lower than the prior year, and decreased
from $1,433,000 in fiscal 1994 to $1,432,000 in fiscal 1995. Selling and
marketing expenses increased $481,000, or 10%, versus fiscal 1994, mainly from
higher personnel costs in the U.S. and Europe, higher convention, meeting,
sample and promotion expenses associated with new product introductions and the
full year impact of the infectious disease product line acquired from ODSI.
General and administrative expenses increased $499,000, or 15%, due to increased
personnel costs in the U.S.


                                       11
<PAGE>   7
and Europe stemming from the higher level of business, an increase in
depreciation from the expanded office facilities plus the full year impact of
depreciation from assets acquired from ODSI and a general increase in the
provision for doubtful accounts to reflect added coverage given the increasing
sales level.

         Operating income increased $1,762,000, or 37%, to $6,576,000 in fiscal
1995 from $4,814,000 in fiscal 1994 primarily due to the factors described
above. As a percent of sales, operating income improved to 26.2% in fiscal 1995
compared to 22.0% in fiscal 1994.

         Other expenses decreased $214,000, or 26%, to $616,000 compared to
$831,000 in fiscal 1994. This decrease was more than accounted for from higher
investment income stemming from an improvement in interest rates compared to
fiscal 1994 plus commission income related to the sale of certain tissue culture
products acquired from ODSI and sold to VAI Diagnostics, Inc. in March 1994.
Gains/losses in foreign exchange were not material in either fiscal year. The
cumulative foreign currency translation adjustment changed by $32,000 during the
year as a result of strengthening of the U.S. dollar against the lira during the
period.

         The Company's effective tax rate increased for the year as a result of
a higher proportion of income from the Company's European subsidiary in Italy,
which is taxed at a significantly higher rate than the U.S. domestic rate. The
effective tax rate was 40.9% in fiscal 1995 compared to 38.7% for the prior
year.

LIQUIDITY AND CAPITAL RESOURCES

         On June 24, 1996, the Company acquired the enteric product line of
Cambridge Biotech Corporation for approximately $6,678,000. The price has been
allocated as follows: an advance on royalties of $200,000; inventory valued at
$830,000; fixed assets valued at $200,000 and intangibles valued at $5,448,000.
This acquisition was funded through liquidation of a portion of the Company's
short-term investments.

         At September 30, 1996, the Company had cash and cash equivalents of
$5,648,000, short-term investments of $14,094,000 and working capital of
$29,656,000. Trade accounts receivable increased $2,723,000, or 42%, primarily
as a result of the significant increase in the fourth fiscal quarter sales of
over 34%, including European sales which were up 27% for the twelve month period
versus the prior year and up 29% for the quarter. Inventories increased
$1,219,000 or 40% largely as a result of the acquisition of the enteric product
line of Cambridge Biotech Corporation.

         Net cash flow provided by operating activities was $4,927,000 for the
twelve month period ended September 30, 1996, up $2,071,000, or 73%, from the
prior year period. This increase resulted primarily from the increase in net
earnings and the increase in depreciation of property, plant and equipment.

         On October 10, 1995, the Company called for redemption of the then
outstanding $7.4 million of its 7 1/4% Convertible Subordinated Debentures due
in 2001. Of the originally issued $11,500,000 principal amount, $113,000 was
redeemed for cash on November 30, 1995. The balance was converted into Common
Stock at $5.97 per share.

         Capital expenditures for the twelve months ended September 30, 1996
were $1,245,000, a decrease of $1,227,000 from the prior year period. The lower
expenditures reflect the completion of construction of additional manufacturing
and administrative space in September 1995. In October 1995, renovation of the
former administrative offices and laboratory manufacturing space commenced. This
phase, which is projected to cost $1,600,000 is expected to be completed by
December 1996. The Company's anticipated total capital expenditures for fiscal
1997 are $1,700,000.


<PAGE>   8
         Over $13.7 million of cash was provided by financing activities in
fiscal 1996, principally the result of the issuance of $20 million of 7%
Convertible Subordinated Debentures issued on September 27, 1996 and due in
2006. The Debentures are convertible into Common Stock at $16.09 per share.
Prior to September 1, 1999, the Debentures may be redeemed if the closing sales
price of the Common Stock equals or exceeds 140% of the then current conversion
price for at least 20 trading days within 30 consecutive trading days ending not
more than five trading days prior to the date of the notice of redemption. On
April 16, 1996, the Company paid off the outstanding balance of its mortgage
loans, reducing long-term debt by $2,418,000.

         On November 18, 1996, the Board of Directors declared the regular cash
dividend of $0.035 per share and a special year-end cash dividend of $0.025 per
share payable December 6, 1996 to shareholders of record on November 28, 1996.
The Board of Directors also announced its intention to increase the regular
annual dividend rate for fiscal 1996 of $0.14 to $0.17 per share for fiscal
1997, representing over a 21% increase in the annual cash dividend rate. Total
dividends paid during fiscal 1996, including a special fiscal 1995 year-end
dividend paid on December 1, 1995 of $354,000, were $2,230,000 compared to
$1,225,000 paid in fiscal 1995.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1)      SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         (a) PRINCIPLES OF CONSOLIDATION -- The consolidated financial
statements include the accounts of Meridian Diagnostics, Inc. and its
subsidiaries, Omega Technologies, Inc., Meridian Diagnostics Europe s.r.l.
("MDE") and Meridian Diagnostics International, Inc. (collectively, "Meridian"
or the "Company"). All significant intercompany accounts and transactions have
been eliminated in consolidation.

         (b) SHORT-TERM INVESTMENTS -- The Company adopted Statement of
Financial Accounting Standards No. 115, "Accounting for Certain Investments in
Debt and Equity Securities" (Statement 115), in 1995. In accordance with
Statement 115, prior years' financial statements have not been restated to
reflect the change in accounting method. There was no cumulative effect as a
result of adopting Statement 115 in 1995.

         Debt securities for which the Company does not have the intent or
ability to hold to maturity are classified as available for sale, along with any
equity securities. At September 30, 1995, the Company's investments in debt and
equity securities were classified as cash and cash equivalents due to their
short-term nature. The estimated fair value of cash investments approximates
cost, and therefore, there are no unrealized gains or losses as of September 30,
1996 or 1995.

         (c) INVENTORIES -- Inventories are stated at the lower of cost,
determined on a first-in, first-out basis, or market.

         (d) PROPERTY, PLANT AND EQUIPMENT -- Property, plant and equipment are
stated at cost. Upon retirement or other disposition of property, plant and
equipment, the cost and related accumulated depreciation and amortization are
removed from the accounts and the resulting gain or loss is reflected in
earnings. Maintenance and repairs are expensed as incurred. Depreciation and
amortization are computed on the straight-line method in amounts sufficient to
write-off the cost over the estimated useful lives as follows:

                  Buildings and improvements -- 5 to 33 years 
                  Machinery, equipment and furniture -- 3 to 10 years

         (e) INTANGIBLE ASSETS -- Intangible assets are stated at cost less
accumulated amortization and are being amortized on a straight line basis over
their estimated useful lives:

                  Covenants not to compete -- 5 to 10 years 
                  License agreements -- 10 to 15 years 
                  Patents, tradenames and distributorships -- 1 to 15 years
                  Cost in excess of net assets acquired and other intangible 
                        assets -- 15 years
                  Deferred debenture offering costs -- 10 years

         Subsequent to their acquisition, the Company continually evaluates
whether subsequent events and circumstances have occurred that indicate the
remaining estimated useful lives of intangible assets may warrant revision or
that the remaining balances of these assets may not be recoverable. When factors
indicate that an intangible asset should be evaluated for possible impairment,
the Company uses an estimate of the related product line's cash flows over the
remaining life of the asset in measuring whether the asset is recoverable.

         In March 1995, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards No. 121 (Statement 121) on
"Accounting for the Impairment of Long-lived Assets and
<PAGE>   14
for Long-lived Assets to be Disposed Of." Statement 121 is required to be
applied prospectively for assets to be held and used. Statement 121 also
establishes accounting standards for long-lived assets that are to be disposed.
The initial application of Statement 121 to assets held for disposal is required
to be reported as the cumulative effect of a change in accounting principle. The
Company is required to adopt Statement 121 no later than fiscal 1997. The
Company will adopt Statement 121 in fiscal 1997 and, based on current
circumstances, does not believe the effect of adoption will have a material
effect on its financial position or results of operations.

         (f) INCOME TAXES -- The provision for income taxes includes federal,
foreign, state and local income taxes currently payable and those deferred
because of temporary differences between income for financial reporting and
income for tax purposes. Research and experimentation credits are reflected as a
reduction in income taxes when realized.

                  Effective October 1, 1993, the Company adopted Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes". The
cumulative effect of this change, as well as the effect of this new standard on
income taxes expense for the year ended September 30, 1994, and for each of the
quarters in the period then ended, was not material.

         (g) EARNINGS PER COMMON SHARE -- Primary earnings per common share are
based on the weighted average number of common shares outstanding during the
year plus any dilutive common stock equivalents. Outstanding stock options,
which are the only common stock equivalent, resulted in per share dilution of
approximately $.01 for fiscal 1996. Fully diluted earnings per share were
dilutive for fiscal 1995 only and included the impact of assuming the
convertible subordinated debentures were converted, net of the impact of pro
forma, after tax interest expense.

                  On September 12, 1995, the Company's Board of Directors
declared a three-for-two stock split to shareholders of record on September 22,
1995. On November 16, 1994, the Company's Board of Directors declared a 3% stock
dividend. On December 1, 1993, the Company's Board of Directors declared a 3%
stock dividend. All data with respect to earnings per share, dividends per share
and weighted average number of shares outstanding has been retroactively
adjusted to reflect the stock splits and stock dividends.

         (h) RESEARCH AND DEVELOPMENT COSTS -- Research and development costs
are charged to earnings as incurred.

         (i) REVENUE RECOGNITION -- Revenue is recognized from sales when a
product is shipped. Income from licensing agreements is recognized as earned and
as stipulated by the respective agreements.

         (j) ADVERTISING -- The Company expenses the cost of advertising as
incurred. Expenditures for advertising in 1996, 1995 and 1994 were approximately
$28,000, $31,000 and $59,000, respectively.

                                       17
<PAGE>   15
         (k) USE OF ESTIMATES -- The preparation of financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.

         (l) TRANSLATION OF FOREIGN CURRENCY -- Assets and liabilities of
foreign operations are translated using year-end exchange rates and revenues and
expenses are translated using exchange rates prevailing during the year, with
gains or losses resulting from translation included in a separate component of

$200,000 on such royalties. The remaining estimated royalty has been accrued at
its present value of $112,000.

affiliate of Ortho Diagnostic Systems, Inc. ("ODSI"), a subsidiary of Johnson &
Johnson, comprised of products used primarily for the detection of certain
infectious diseases including Chlamydia, Herpes and various viral respiratory
infections. The Company also acquired inventory, equipment, certain license

                  The 7 1/4% Convertible Debentures were called for redemption 
on October 10, 1995. Holders of the Debentures had the option of converting 
their Debentures into shares of Meridian Diagnostics' common stock prior to the
redemption date of November 30, 1995, at a conversion price of $5.97 per share
or, upon delivery of the Debentures, receiving cash. The Debentures not
converted were redeemed at 105% of their face amount plus accrued interest. Of
the originally issued $11,500,000 principal amount, $113,000 was redeemed for
cash. The balance was converted at the conversion price of $5.97 per share,
equivalent to a conversion rate of 167.5 shares per each $1,000 principal amount
of Debentures. Through September 30, 1995, $3,520,000 of Debentures were
converted to common stock net of $186,000 of deferred debenture offering costs,
which were charged to additional paid-in capital. As of November 30, 1995, the
balance, net of the $113,000 redeemed, of $7,867,000 of Debentures were
converted to common stock net of $457,000 of deferred debenture offering and
other related costs, which were charged to additional paid-in-capital.

                  As part of a bank credit arrangement the Company has a
$10,000,000 line of credit which expires on May 27, 1997 and calls for interest
at prime floating or the LIBOR rate plus 2.75%. There were no borrowings
outstanding on the line of credit at September 30, 1996. In connection with the
bank credit arrangement, the Company has agreed, among other things, to meet
certain financial ratio requirements and to limit additional indebtedness.

     Maturities on the above long-term obligations are as follows:

(7)      EMPLOYEE BENEFITS

         (a) SAVINGS AND INVESTMENT PLAN--The Company has a profit sharing and
retirement savings plan covering substantially all full-time employees. Profit
sharing contributions to the plan, which are discretionary, are determined by
the Board of Directors. The plan permits participants to contribute to the plan
through salary reduction. Under the terms of the plan, the Company will match up
to 3% of an employee's contributions.
<PAGE>   23
Discretionary and matching contributions by the Company to the plan amounted to
approximately $269,000, $273,000, and $270,000, during 1996, 1995 and 1994,
respectively.

         (b) STOCK OPTIONS--At September 30, 1996, 1,641,235 of the authorized
but unissued common shares of the Company were reserved for issuance to
directors, executives, employees and consultants for stock options. Of the
reserved shares, 810,594 were subject to options outstanding at September 30,
1996. Options may be granted at exercise prices from 95% to 110% of the market
value of the underlying common stock on the date of grant and become exercisable
on vesting schedules established at the time of grant. All options contain
provisions restricting their transferability and limiting their exercise in the
event of termination of employment or the disability or death of the optionee.
Options may be granted both as incentive stock options designed to provide
certain tax benefits under the Internal Revenue Code and as nonqualified options
without such tax benefits.

options in 1996 and 14,574 in 1995.

         In October 1995, the FASB issued Statement of Financial Accounting
Standards No. 123 (Statement 123) "Accounting for Stock Based Compensation"
establishing financial accounting and reporting standards for stock-based
employee compensation plans. Statement 123 encourages the use of the fair value
based method to measure compensation cost for stock-based employee compensation
plans; however, it also continues to allow the intrinsic value based method of
accounting as prescribed by APB Opinion No. 25, which is currently used by the
Company. If the intrinsic value based method continues to be used, Statement 123
requires pro forma disclosures of net income and earnings per share, as if the
fair value based method of accounting had been applied. The fair value based
method requires that compensation cost be measured at the grant date based upon
the value of the award and recognized over the service period, which is normally
the vesting period. The Company intends to adopt Statement 123 in fiscal 1997 by
making the required footnote disclosures only. Therefore, the adoption of this
Statement is not expected to have a material effect on the Company's financial
position or results of operations.

         (c) OTHER BENEFITS--the Company does not provide postretirement or
postemployment benefits to its employees.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Meridian Diagnostics, Inc.:

         We have audited the accompanying consolidated balance sheets of
MERIDIAN DIAGNOSTICS, INC. and subsidiaries as of September 30, 1996 and 1995,
and the related consolidated statements of earnings, shareholders' equity, and
cash flows for each of the three years in the period ended September 30, 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 financial statements referred to above present
fairly, in all material respects, the financial position of Meridian
Diagnostics, Inc. and subsidiaries as of September 30, 1996 and 1995, and the
results of their operations and their cash flows for each of the three years in
the period ended September 30, 1996, in conformity with generally accepted
accounting principles.
