PART I
ITEM 1. BUSINESS

The Company is a worldwide provider of proprietary quality control
products for use with in vitro diagnostic test kits ("test kits") for the
detection, analysis and monitoring of infectious diseases, including AIDS,
Hepatitis and Lyme Disease. These products are used to develop test kits, to
permit the monitoring of laboratory equipment and personnel, and to help ensure
the accuracy of test results. The Company's products are derived from human
plasma and serum using proprietary manufacturing processes. The Company
believes its Quality Control Panel products are viewed as the current industry
standard for the independent assessment of the performance of HIV and Hepatitis
test kits. The Company also manufactures diagnostic test kit components,
laboratory instruments, and provides specialty laboratory services, including
clinical trials. It also provides contract instrument development and related
repairs at its service center in Garden Grove, CA. The Company's customers
include test kit manufacturers, regulatory agencies and end-users of test kits
such as blood banks, hospital laboratories and clinical reference laboratories.
Currently the Company's products are used in connection with the detection of
more than 15 infectious diseases, and its specialty laboratory services are
used in connection with the detection of over 100 such diseases.

The Company's strategy is to leverage its scientific capabilities in
microbiology, immunology, virology, and molecular biology to (i) capitalize on
the emerging end-user market, (ii) develop new products and services, (iii)
enhance technical leadership, (iv) capitalize on complementary business
operations, and (v) pursue strategic acquisitions and alliances.

Industry Overview

Infectious Disease Test Kits and Testing Methods. Test kits contain in
one compact package all of the materials necessary to run a test for an
infectious disease. These include the disposable diagnostic components,
instructions, and reaction mixing vessels (generally 96-well plates or test
tubes) which are coated with the relevant infectious disease antigens,
antibodies or other materials. To perform the test, either a technician or a
specially designed instrument typically mixes the solutions from the test kit
with human blood specimens in a specific sequence according to the test kit
instructions. The mixture must then "incubate" for up to 18 hours, during which
time a series of biochemical reactions trigger signals (including color, light
and radioactive count) which indicate the presence or absence and amount of
specific markers of the particular disease in the specimen.

Test kits generally employ one of three methods for infectious disease
testing: microbiology, immunology or molecular biology. Traditional
microbiology tests use a growth medium that enables an organism, if present, to
replicate and be detected visually. Immunology tests detect the antigen or
antibody, which is an indicator (marker) of the pathogen (e.g., virus,
bacterium, fungus or parasite). Molecular diagnostic methods, such as the
polymerase chain reaction ("PCR"), test for the presence of nucleic acids (DNA
or RNA) which are specific to a particular pathogen.

Most infectious disease tests currently use microbiological or
immunological methods. However, molecular diagnostic methods are increasingly
being used in research and clinical laboratories worldwide. The Company
believes that the advent of molecular diagnostic methods will complement rather
than diminish the need to test by microbiological and immunological procedures,
because different test methods reveal different information about a disease
state. The Company anticipates that as new test methods become more widespread,
they will account for a larger portion of the Company's business.

Quality Control for In Vitro Diagnostic Test Kits. Customers employ
quality control products in order to develop and use test kits (both infectious
and non-infectious). Quality control products help ensure that test kits detect
the correct analyte (specificity), detect it the same way every time

-2-

(reproducibility or precision), and detect it at the appropriate levels
(sensitivity). The major element of this quality control process is the
continuous evaluation of test kits by the testing of carefully characterized
samples that resemble the donor or patient samples routinely used with the
test. Quality control is used in both the infectious and non-infectious disease
markets, although currently it is not as prevalent among end-users of
infectious disease test kits.

The market for quality control products consists of three main customer
segments: (i) manufacturers of test kits, (ii) regulatory agencies that oversee
the manufacture and use of test kits and (iii) end-users of test kits, such as
hospitals, clinical reference laboratories and blood banks.

Company Products and Services

Overview

The Company offers two broad product classes used in in vitro
diagnostics ("IVD"): "Diagnostic Products" consisting of Quality Control
Panels, Accurun( Run Controls and Diagnostic Components, all used in connection
with infectious disease testing, and new for 1997, "Laboratory Instruments".
Diagnostic Products are used throughout the entire test kit life cycle, from
initial research and development, through the regulatory approval process and
test kit production, to training, troubleshooting and routine use by end-users.
The Company's Quality Control Panels, which combine human blood specimens with
comprehensive quantitative data useful for comparative analysis, help ensure
that test kits detect the correct analyte (specificity), detect it the same way
every time (reproducibility), and detect it at the appropriate levels
(sensitivity). The Company's Accurun( Run Controls enable end-users of test
kits to confirm the validity of results by monitoring test performance, thereby
minimizing false negative test results and improving error detection. In
addition, the Company provides Diagnostic Components, which are custom
processed human plasma and serum products, to test kit manufacturers.

Through its wholly owned subsidiary, BBI Source Scientific, Inc., the
Company designs, manufactures and markets Laboratory Instruments used in
hospitals, clinics, and research, environmental and food testing laboratories.
Utilizing a common hardware technology platform, these instruments are used in
connection with the performance of an IVD test, including reading the test
result.

The Company's specialty clinical laboratory services include both
routine and sophisticated infectious disease testing in microbiology,
immunology and molecular biology. The Company seeks to focus its specialty
laboratory services in advanced areas of infectious disease testing, and
provides contract research and clinical trials for the United States government
and for domestic and foreign test kit manufacturers.

Diagnostic Products

The Company manufactures its Diagnostic Products from human plasma and
serum which are obtained from nonprofit and commercial blood centers, primarily
in the United States. The Company has acquired and developed an inventory of
approximately 50,000 individual blood units and specimens (with volumes ranging
from 1 ml to 800 ml) which provides most of the raw material for its products.
Within the Diagnostic Products class are two groups: Quality Control Products
(Panels and Accurun( Run Controls) and Diagnostic Components.

Quality Control Panels

Quality Control Panels consist of blood products characterized by the
presence or absence of specific disease markers and a Data Sheet containing
comprehensive quantitative data useful for comparative analysis. These Quality
Control Panels are designed for measuring overall test kit

-3-

performance and laboratory proficiency, as well as for training laboratory
professionals. The Company's Data Sheets, containing comprehensive
quantitative data useful for comparative analysis, are an integral part of its
Quality Control Panels. These Data Sheets are created as the result of
extensive testing of proposed panel components in both the Company's
laboratories and at major testing laboratories on behalf of the Company in the
United States and Europe, including national public health laboratories,
research and clinical laboratories and regulatory agencies. These laboratories
are selected based on their expertise in performing the appropriate tests on a
large scale in an actual clinical setting; this testing process provides the
Company's customers with the benefit that the Quality Control Panels they
purchase from the Company have undergone rigorous testing in actual clinical
settings. In addition, the Company provides information on its Data Sheets on
the reactivity of panel components in all FDA licensed test kits and all
leading European test kits for the target pathogen, as well as for all other
appropriate markers of this pathogen. For example, the Company's HIV panel Data
Sheets include anti-HIV by IFA, ELISA and western blot; HIV antigen by ELISA;
and HIV RNA by several molecular diagnostic procedures. The Company's Data
Sheets require significant time and scientific expertise to prepare. The
following table describes the types of Quality Control Panel products currently
offered by the Company.

-4-

The Company first introduced Quality Control Panels in 1987. The
Company currently offers a broad range of Quality Control Panels that address a
variety of needs of manufacturers and regulators of test kits as well as blood
banks, hospitals, clinical laboratories and other end-users. Prices for the
Company's quality control seroconversion, performance and sensitivity panels
range from $450 to $2,000 each, and its qualification and OEM panels range from
$100 to $200 per panel.

Seroconversion and Performance Panels are comprised of unique and rare
plasma specimens obtained from individuals during the short period of time when
the markers for a particular disease are converting from negative to positive.
As a result, the quantity of any such panel is limited, so that the Company
must replace these panels as they sell out with another panel comprised of
different specimens equally unique and rare. The Company believes that its
inventory and relationships with blood centers affords it a competitive
advantage in acquiring such plasma for replacement panels and developing new
products to meet market demand. There can be no assurance that the Company will
be able to continue to obtain such specimens.

Quality Control Panels currently span the immunologic markers for AIDS
(i.e., HIV), Hepatitis (A, B and C), Lyme Disease and ToRCH (Toxoplasma,
rubella, cytomegalovirus and herpes simplex virus). New introductions this year
include Performance Panels for HIV, EBV and HCV, Qualification Panels for HIV,
HTLV, CMV and HCV, and additional Seroconversion Panels for HIV and HCV.
Included in the Performance Panel category are the first "Worldwide" panels for
HCV and HIV that include specimens from throughout the world reactive for
variants and subtypes of these deadly viruses.

Accurun(r) Run Controls

End-users of test kits utilize Run Controls to confirm the validity of
results by monitoring test performance, thereby minimizing false negative test
results and improving error detection. Run controls consist of one or more
specimens of known reactivity that are tested together with donor or patient
samples in an assay to determine whether the assay is performing within the
manufacturer's specifications. Clinical laboratories generally process their
patient specimens in a batch processing mode, and typically include 25 to 100
specimens to be tested in each batch (a "run"). Large laboratories may perform
several runs per day, while smaller laboratories may perform only a single run
each day, or sometimes only several runs per week. A clinical laboratory using
a Run Control will place the Run Control product in a testing well or
test-tube, normally used for a specimen, and will test it in the same manner
that it tests the donor or patient specimens. It will then compare the results
generated to an acceptable range, determined by the user, to measure whether
the other specimens are being accurately tested. The Run Control result must be
within the acceptable range to be considered valid. This is often tracked
visually using a Levey-Jennings chart. Depending upon a particular laboratory's
quality control practices, it may use several Run Controls on each run or it
may simply use a Run Control in a single run at the beginning and end of the
day.

In 1997, the Company introduced its AccuChartTM tracking and charting
software. Used as part of a laboratory's quality assurance program, AccuChartTM
runs on a PC and is designed to provide the data tracking capability needed to
document laboratory performance.

The Company's Accurun(r) family of products is targeted at the emerging
market of end-users of infectious disease test kits. The Company believes that
it offers the most comprehensive line of Run Controls in the industry, and that
its Accurun(r) products, in combination with its Quality Control Panel
products, provide an extensive line of products for quality assurance in
infectious disease testing. The Company intends to continue to expand its line
of Accurun(r) products, thereby providing its customers with the convenience
and cost effectiveness of a single supplier for independent run controls.

The Company introduced its first four Accurun(r) Run Control products
in the fourth quarter of 1993 and has since developed and released for sale an
additional 31 Accurun(r) products, for a total of 35

-5-

Run Controls. The majority of these products are available for diagnostic
purposes; the others currently are limited to research use. Current Accurun(r)
Run Control products range in price from $5 to $45 per milliliter and are
described in the following table.

All of the Company's Accurun(r) Run Controls require FDA premarket
clearance (a 510(k)) prior to being marketed for diagnostic use, under current
FDA rules. The FDA Modernization Act of 1997 will likely produce new
regulations exempting some of these products from FDA submission requirements,
but the new rules are not yet in place. As of March 1, 1998, a total of nine
products in the Accurun 1(r) line and 14 single analyte Accurun( controls have
received 510(k) clearance from the FDA. An additional three Accurun(r) single
analyte products have been submitted but have not yet received FDA approval.

Diagnostic Components

Diagnostic Components are the individual materials supplied to
infectious disease test kit manufacturers and combined (often after further
processing by the manufacturer) with other materials to become the various
fluid components of the manufacturer's test kit. The Company supplies
Diagnostic Components in four product lines: Normal Human Plasma, Normal Human
Serum, Basematrix, and Characterized Disease State Serum and Plasma. Normal
Human Plasma and Serum are both the clear liquid portion of blood which
contains proteins, antibodies, hormones and other substances, except that the
Serum product has had the clotting factors removed. Basematrix, the Company's
proprietary processed serum product that has been chemically converted from
plasma, is designed to be a highly-stable, lower cost substitute for most
Normal Human Serum and Plasma applications. Characterized Disease State Serum
and Plasma are collected from specific blood donors pre-selected because of the
presence or absence of a particular disease marker. The Company often
customizes its Diagnostic Components by further processing the raw material to
meet the specifications of the test kit manufacturer. The Company's Diagnostic
Components range in price from $0.25 to $60 per milliliter, with the majority
selling between $0.50 and $5 per milliliter.

Laboratory Instruments

In 1997, the Company acquired the business and net assets of Source
Scientific, Inc., a laboratory instrument manufacturer in Garden Grove,
California. As a result of this acquisition, the Company through its wholly
owned subsidiary, BBI Source Scientific, Inc. ("BBI Source"), now has expertise
in IVD instruments, adding to its existing capability in IVD quality control
products. This is significant since, in addition to the test kit and a well
trained technician, the third element to an accurate test result is a properly
calibrated instrument to read the test result. See also Note 2 to the Company's
Notes to Consolidated Financial Statements in Item 8 hereunder regarding the
Company's purchase of the business and net assets of Source Scientific, Inc.

BBI Source designs, manufactures and markets Laboratory Instruments
used in hospitals, clinics, and research, environmental and food testing
laboratories. They are generally sold on a private-label or OEM basis for other
companies utilizing a common hardware technology platform. The instruments
manufactured by the Company use advanced optical detection methods
(luminescence, fluorescence, reflectance, photometry), robotics, fluidics, and
unique software, which is desired by customer companies reselling the
state-of-the-art instrumentation systems to clinical distributors and
laboratories worldwide.

The products currently being offered by BBI Source have been
commercialized since 1985. BBI Source expects that its newest products will be
available for production in late 1998. Management believes that products address
important market segments in biomedical and clinical diagnostic testing and
environmental monitoring and food testing research. The BBI Source product line
includes the following:

MicroChem(r) Photometer. A compact, low-cost, photometer designed for
immunoassay and general chemistry applications.

ChemStat(r) Automated Photometer. A high-speed, automated photometer
with a sample capacity of 95 tubes and a read rate of one sample per second.
This product is suited for high-volume processing.

ChemStat(r) Plus Automated Photometer. The ChemStat Plus is a second
generation photometer compatible with the EXEC-WASH Washing System that
features menu-driven software and optional on-board dispensers.

E/LUMINA(r) Luminescence Analyzer. A flexible luminometer for both
"flash" and "glow" luminescence methods, this automated system reads up to 114
samples and reports final results.

E/LUMINA(r) 2E Automated Luminescence Analyzer. This detection system
is designed with the same features as the E/LUMINA Luminescence Analyzer that
can be used to detect faster "flash" luminescence techniques and adapts to
various formats, as well as to liquid phase assays.

EXEC-WASH(r) Washing System. An automated immunoassay washing system
that can be quickly configured by the user to wash different solid-phase assay
formats by a propriety manifold design. The EXEC-WASH is fully compatible with
a variety of other Company products, such as the ChemStat, the ChemStat Plus
and the E/LUMINA Luminescence Analyzer.

PlateMate(r) Reader. The Company expects to have available in 1998 the
PlateMate Reader, a microfluidics well-reading system combining robotics and
fluidics. The current design of the PlateMate Reader performs photometric
assays in the 400 to 700 nm range for 96 samples at a time and prints out
results directly on a built-in printer.

-7-

Protocol Design Software System. A development tool for researchers and
assay manufacturers, the program operates under Microsoft(r) Windows and serves
as the master programing center for EXEC-WASH systems to create fluid handling
protocols.

FOCUS(r). Florescence Polarization System. Fluorescence polarization
("FP") is a technology that has dominated the clinical market for therapeutic
and abuse drug level testing for many years.

FluoroStat(r) Reader. The FluoroStat is a compact fluorometer that is
highly sensitive and provides a broad dynamic range for tube-based fluorometric
assays. The instrument was introduced in September 1995 and is currently
available for OEM manufacture.

Services

The Company seeks to focus its specialty laboratory services in both
the clinical reference laboratory testing and advanced research areas. The
Company concentrates its services in those areas of infectious disease testing
which are complementary to its quality control and diagnostic products
businesses.

Specialty Clinical Laboratory Testing. Through its wholly owned
subsidiary, BBI Clinical Laboratories, Inc. the Company operates an independent
specialty clinical reference laboratory which performs both routine and
sophisticated infectious disease testing in microbiology, immunology and
molecular biology, with special emphasis in AIDS, Viral Hepatitis and Lyme
Disease. The Company's specialty clinical laboratory combines traditional
microbiology, advanced immunology, and current molecular diagnostic techniques,
such as PCR, to detect and identify microorganisms, their antigens and related
antibodies, and their nucleic acids (i.e., DNA and RNA). Customers include
physicians, clinics, hospitals and other clinical/research laboratories.

Contract Research. The Company, through its wholly owned subsidiary,
BBI Biotech Research Laboratories, Inc. ("BBI Biotech"), offers a variety of
contract research services in molecular biology, cell biology and immunology to
governmental agencies, diagnostic test kit manufacturers and biomedical
researchers. Molecular biology services include DNA sequencing, recombinant DNA
support, probe labeling and custom PCR assays. Cell biology and immunology
services include sterility testing, virus infectivity assays, cultivations of
virus or bacteria from clinical specimens, preparation of viral or bacterial
antigens or nucleic acids, and production of antibodies. The Company is
currently providing contract research services under several contracts and
grants. These services primarily related to infectious diseases, and include
the following: assessment of the efficiency of candidate HIV vaccines in a
monkey model system; development of a multiplex RT PCR based test for HIV-1,
HTLV I/II, HCV, and HBV; DNA sequencing of human genes involved in neurological
disorders; plate assays for HIV-1 genotyping; and eliciting neutralizing
antibodies targeting HIV. In addition, since 1983, BBI Biotech, has provided
blood processing and repository services for the National Cancer Institute
("NCI"), also a part of the National Institutes of Health ("NIH"). The
repository stores over 2,000,000 specimens and processes or ships up to several
thousand specimens per week in support of various NIH cancer and virus research
programs. A new one year NCI repository contract was signed in February 1997
which includes four one year renewal options exercisable by NCI. The total
value of the contract in the first year is $916,000, and including all options,
is $4.8 million. The initial renewal option has been approved by the NCI
although there can be no assurance that any subsequent options will be
exercised.

Clinical Trials. The Company conducts clinical trials for domestic and
foreign test kit manufacturers. Test kit manufacturers must conduct such trials
to collect data for submission to the United States FDA and other regulatory
agencies. By providing this service, the Company is able to maintain close
contact with test kit manufacturers and regulators, and is able to evaluate new
technologies in various stages of development. The Company believes that the
reputation of its laboratory and scientific staff, its large number of Quality
Control Panels, and its inventory of

-8-

characterized serum and plasma specimens assist the Company in marketing its
clinical trial services to its customers. The Company has performed clinical
trials for a number of United States and foreign test kit manufacturers seeking
to obtain FDA approval for their infectious disease test kits.

Laboratory Instrumentation Services. BBI Source offers design,
development and manufacturing services to companies seeking to market
biomedical products manufactured under government-approved manufacturing
practices. The OEM services range in complexity from contract manufacturing to
full system development and distribution.

BBI Source also provides after-sales-service. Management believes that
after-sales service is a major marketing advantage in many of the Company's
markets, since many of the Company's customers do not maintain their own full
service departments. Servi-Trak(r), a proprietary software program, is a key
element of this after-sales service. The Company's service department is
located at BBI Source's facility in Garden Grove, California. A fully
functional service center located in Giessen, Germany, is contracted by the
Company to provide European service and support.

On March 9, 1998, the Company announced plans to modify a previously
announced 3-year contract with ABX Hematology, Inc. ("ABX") and its parent
company, ABX Hematologie, SA (France). Under the contract, the Company provided
technical, customer and field services for instruments sold by ABX in the
United States. Under the modified agreement, individual customer service
contracts will be assigned to ABX and ABX will assume responsibility for its
United States instruments. The Company will provide certain consulting services
through March 1999 to assist ABX in establishing a sales, customer service,
technical support, and field service operation in the United States for its
hematology instrument and reagent business. In addition, the Company has agreed
to allow ABX to occupy space at its California facility during the period of
the agreement. The Company's personnel associated with this contract, included
the nationwide field service organization and hotline technical support, will
be offered employment by ABX.

Drug Screening Program. As a subcontractor for an NIH AIDS grant held
by the University of North Carolina at Chapel Hill, the Company has established
an anti-HIV drug screening program to test a large number of natural products
(largely plant derivatives) to determine whether they inhibit HIV replication
in an in vitro assay system. These in vitro assays are also offered as a
service to researchers and pharmaceutical companies who wish to test various
candidate anti-viral agents for anti-HIV activity.

Research and Development

The Company's research and development effort is focused on the
development of (i) new and improved Quality Control Products (Panels and
Accurun(r)) for the emerging end-user market, (ii) new products for existing
customers, (iii) Diagnostic Components for use with test kits for both new test
methodologies and new diseases, (iv) new laboratory instruments and mechanical
and optical detection techniques, and (v) infectious disease testing services
using PCR and other amplification assays for AIDS, Viral Hepatitis, Lyme
Disease and Chlamydia, among others. The Company has approximately 36 full or
part-time employees involved in its research and development effort. For 1997
the Company increased spending on research and development as a percentage of
revenues compared to 1996 and expects to continue to increase such expenditures
as a percentage of revenues for the next several years. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Results of Operations." The Company's research scientists work closely with
sales, marketing, manufacturing, regulatory and finance personnel to identify
and prioritize the development of new products and services.

The Company's product development activities center on the
identification and characterization of materials for the manufacture of new
Quality Control Products and the replacement of sold-out products. During 1997,
the Company introduced 32 new Seroconversion, Performance, Sensitivity and
Qualification Panel products, as well as 6 new Accurun(r) Run Controls, and 34
OEM Panels. The

-9-

Company is developing new Quality Control Products for use with both
immunological and molecular diagnostic tests for subtypes and variants of HIV,
HCV and HBV, and a variety of controls targeted for leading instrument
platforms. The Company has increased the number of off-the-shelf Quality
Control Products it offers from approximately 20 products in 1990 to
approximately 167 in 1997.

The Company's product development activities related to Laboratory
Instruments are centered on additional configurations for its PlateMate(r)
microtiter plate reader and the development of a "reflectance" reader to
produce qualitative results from rapid IVD tests using dry chemistry (strip)
technology. In addition, the Company continues to work on applications for
existing products to broaden their utilization.

The Company is also developing new and improved infectious disease
tests which offer potential for above average profit for use in its specialty
laboratory business. This includes emphasis on additional applications of PCR
and other amplification technologies to infectious disease diagnostics, beyond
its current assays for the pathogens of AIDS, Viral Hepatitis, Lyme Disease and
Herpes, and for the direct detection of other infectious agents in blood,
tissues and other body fluids.

From time to time in the past, the Company has funded a portion of its
research and development activities from grants provided by various agencies
and departments of the United States government. See also "-Services-Contract
Research."

Strategic Alliances

University of North Carolina at Chapel Hill ("UNC"). The Company is
directly supporting a drug discovery program at UNC, in which a full-time
research scientist is working to develop synthetic derivatives of anti-HIV
compounds that have been discovered pursuant to the Company's joint
collaboration with UNC. This research scientist is also working to introduce
modifications to these derivatives that would make them more soluble, less
toxic, or otherwise enhance their anti-viral properties. UNC has licensed to
the Company exclusive worldwide rights to three series of patent applications
filed by the Company and UNC with respect to three classes of anti-HIV
compounds. Two such compounds have exhibited therapeutic indices in in vitro
test model systems in excess of those recorded for AZT under comparable test
conditions. The Company is expending approximately $150,000 per year for
research and development relating to these compounds. In addition, under this
license, the Company will also have the rights to any new anti-HIV compounds or
derivatives developed in the course of this sponsored research, provided the
Company obtains certain regulatory approvals from the FDA. See also
"-Services-Drug Screening program."

Ajinomoto Co., Inc. The Company entered into an agreement with
Ajinomoto Co., Inc. in October 1995 pursuant to which the Company is performing
research regarding among other things, whether tests for certain amino acids in
plasma can be used to determine a person's immune status, particularly in
chronic fatigue syndrome. This project is funded by Ajinomoto and has a three
year budget of approximately $1,000,000. Discoveries and inventions arising
from the research will be owned by Ajinomoto, but the Company has the right of
first refusal to obtain certain exclusive licenses from Ajinomoto of any
patented technology arising from the research. The Company is entitled to
certain royalties based upon a percentage of sales of products arising out of
the research. This agreement expires in September 1998. The Company does not
know if the contract will be renewed.

BioSeq, Inc. In October 1996, the Company entered into a strategic
alliance with BioSeq, Inc. an early stage biotechnology company that is
developing a technology that may, through the use of pressure, be able to more
precisely control chemical reactions. The Company believes that this technology
may be useful for sample preparation in connection with both molecular and
immunological testing, process purification, sequencing, synthesizing and
characterizing nucleic acids and proteins, which may then allow for the more
precise identification of infectious disease agents. See also Note 5 to the
Company's

Notes to Consolidated Financial Statements in Item 8 hereunder regarding the
Company's investment in BioSeq, Inc. The Company, in a seperate transaction,
purchased a licensed technology from BioSeq, Inc. on March 20, 1998. See also
Note 14 to the Company's Note to Consolidated Financial Statements and Item 8
hereunder regarding subsequent event.

Sales and Marketing

The Company's sales and marketing efforts are directed by a Senior Vice
President of Sales and Marketing and includes 25 sales people and 9 other
full-time marketing and customer services employees.

The Company's marketing strategy is focused upon addressing the needs
of its customers in the infectious disease testing market throughout the entire
test kit life-cycle, from initial research and development, through the
regulatory approval process and test kit production, to training,
troubleshooting and routine use by end-users such as clinical laboratories,
hospitals and blood banks.

The Company recently has begun to focus its sales and marketing efforts
on the emerging end-user market for quality control products for infectious
disease test kits. To promote this objective, the Company has implemented a
major marketing platform, known as "Total Quality System" ("TQS"). TQS is a
package of Quality Control Products, including the Company's Accurun(r) Run
Controls, which is designed to provide test kit end-users with the products
needed in an overall quality assurance program. These products enable
laboratories to evaluate each of the key elements involved in the testing
process: the test kit, laboratory instrument and laboratory personnel. The
Company believes that TQS effectively addresses the need for end-users to
ensure the accuracy of their test results. The Company intends to continue to
expand its sales and marketing activities with respect to its Accurun(r) line
of run control products.

The Company's products are currently sold through a combination of
telephone, mail, third party distributors and direct sales efforts.
Domestically, Diagnostic Products are sold through a direct sales force
consisting of a sales director, three regional managers and nine sales
representatives. Internationally, the Company distributes its Diagnostic
Products both directly and through 21 independent distributors located in
Japan, Australia, South America, Southeast Asia, Israel and Europe. The
Company's international sales manager oversees the Company's foreign
distributors. The Company's Laboratory Instruments are sold through a direct
domestic and international sales force consisting of two sales managers. Export
sales, including sales to distributors, for the years ended December 31, 1995,
1996, and 1997 were $3.4 million, $4.3 million, and $5.2 million, respectively.
See also Note 6 to the Consolidated Financial Statements.

The Company's Specialty Clinical Laboratory Testing services are
marketed primarily through a direct domestic sales force consisting of seven
sales representatives managed by a sales director. The sales representatives
are located throughout the eastern and mid-western United States. They are
supported internally by a client services representative.

The Company emphasizes high quality products and services, technical
knowledge, and responsiveness to customer needs in its marketing activities for
both products and services. The Company educates its distributors, customers
and prospective customers about its products through a series of detailed
marketing brochures, technical bulletins and pamphlets, press releases and
direct mail pieces. These materials are supplemented by advertising campaigns
in major industry publications, technical presentations, and exhibitions at
local, national and international trade shows and expositions.

-11-

Customers

The Company's customers for Diagnostic Products comprise three major
groups: (i) international diagnostics and pharmaceutical manufacturing
companies, such as Abbott Diagnostics, Behring, Boehringer Mannheim, Chiron,
Fujirebio, Hoffman LaRoche, Ortho Diagnostics (Johnson and Johnson), Sanofi
Diagnostics and Sorin Biomedica; (ii) regulatory agencies such as the United
States FDA, the British Public Health Laboratory Service, the French Institut
National de la Transfusion Sanguine, and the German Paul Ehrlich Institute; and
(iii) end-users of diagnostic test kits, such as hospital and independent
clinical laboratories, including LabCorp, Quest and Smith Klein Beecham, public
health laboratories and blood banks, including the American Red Cross, Swiss
Red Cross, United Blood Services and Kaiser Permanente. The Company's customers
for Laboratory Instruments consist of international diagnostic and
pharmaceutical manufacturing companies and are generally sold on an OEM basis,
for use by hospitals, and clinical and research laboratories. In addition,
Laboratory Instruments are sold directly to environmental and food testing
laboratories, and wineries. Customers include Mast Immuno Systems, ABX
Hematology, Hybritech Inc., Vicam, and Toray Fuji Bionics Inc. The Company's
Specialty Clinical Laboratory Testing services are sold to hospital and
clinical laboratories, physicians, blood banks, researchers and other health
care providers. The Company's Contract Research services are typically offered
under contracts to governmental agencies, diagnostic test kit manufacturers and
biomedical researchers.

The Company does not have long-term contracts with its customers for
Quality Control Products and Diagnostic Components. The Company's products are
sold to its customers pursuant to purchase orders for discrete purchases.
Laboratory Instruments sold on an OEM basis are usually done so under a one
year contract with monthly delivery dates. Although the Company believes that
its relationships with customers are satisfactory, termination of the Company's
relationship with any one of its customers could have a material adverse effect
on the Company.

During the fiscal years 1995, 1996 and 1997, sales to the Company's
three largest customers accounted for an aggregate of approximately 20% of the
Company's net sales, although the customers were not identical in each period.
During the fiscal years 1995, 1996 and 1997, the combined revenues to all
branches of the National Institutes of Health, a United States Government
agency, accounted for approximately 13% of total consolidated revenues of the
Company. While the Company believes that the loss of any one customer would
have an adverse effect on its results, this risk is partially mitigated by the
diversity of its customer base within the IVD industry and the different
diseases and instrument platforms on which they focus.

Manufacturing and Operations

The Company manufactures and assembles Diagnostic Products at its
facility in West Bridgewater, Massachusetts. Raw materials (primarily plasma
and serum) are acquired from a variety of vendors and through a program of
donor recruitment, screening, management, and plasma/serum collection and
characterization. All important materials have multiple sources of supply.
Laboratory Instruments are manufactured and assembled at the Company's facility
in Garden Grove, California. Raw materials and subassemblies are acquired from
a variety of vendors with multiple sources of supply.

The Company also operates a specialty clinical laboratory in New
Britain, Connecticut, and a research and development laboratory in
Gaithersburg, Maryland. See "Item 2 -- PROPERTIES."

Competition

The market for the Company's products and services is highly
competitive. Many of the Company's competitors are larger than the Company and
have greater financial, research, manufacturing, and marketing resources.
Important competitive factors for the Company's products include product

-12-

quality, price, ease of use, customer service and reputation. In a broader
sense, industry competition is based upon scientific and technical 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 products and services do not reflect technological advances, the
Company's ability to compete in those products and services could be adversely
affected.

In the area of Quality Control Products, the Company competes in the
United States with NABI (formerly North American Biologicals, Inc.) in run
controls and quality control panel products. with Dade International, Bio-Rad
Laboratories, Inc., and Blackhawk Biosystems Inc. in run controls, and with a
number of smaller, privately held companies in quality control panels. In
Europe, in addition to the above, the Netherlands Red Cross has recently begun
offering several run control and panel products. The Company believes that all
of these competitors currently offer a more limited line of panel and run
control products than the Company, although there can be no assurance these
companies will not expand their product lines.

In the Diagnostic Components area, the Company competes against
integrated plasma collection and processing companies such as Serologicals,
Inc. and NABI, as well as smaller, independent plasma collection centers and
brokers of plasma products. In the Diagnostic Components area, the Company
competes on the basis of quality, breadth of product line, technical expertise
and reputation.

The laboratory instrument manufacturing industry is diverse and highly
competitive. The Company believes its technology base, reputation for
reliability, systems integration and service capabilities provide it with a
competitive advantage over its competitors which include: Dynatech Corp,
Kollsman Manufacturing Company, Inc., Bio-Tek Instruments Inc., Rela Inc. (part
of Colorado Medtech, Inc.), as well as numerous, smaller companies, such as
Awareness Technology Inc.

In the Specialty Clinical Laboratory Testing services portion of the
Company's business, it competes with large national reference laboratories,
such as LabCorp of America, Quest Laboratories and SmithKline Beecham Clinical
Laboratories, as well as several independent regional laboratories, hospital
laboratories, government contract laboratories and large research institutions.
The Company believes that by focusing on the specialty clinical laboratory
market, it is able to offer its customers a higher value-added service on the
more complex diagnostic tests than the larger national reference laboratories.

Intellectual Property

The Company holds as trade secrets current technology used to prepare
Basematrix and other blood-based products. None of the Company's Quality
Control Products or Diagnostic Components has been patented. The Company relies
primarily on a combination of trade secrets and non-disclosure and
confidentiality agreements to establish and protect its proprietary rights in
its technology and products. There can be no assurance that others will not
independently develop or otherwise acquire the same, similar or more advanced
trade secrets and know-how.

BBI Source has also relied on trade secrets and proprietary know-how
for its Laboratory Instruments which it protects in part by entering into
confidentiality agreements with persons or parties deemed appropriate by
management. In addition, the Company currently has five issued United States
patents, and one United States patent application on file, covering significant
aspects of the Company's core instrument technology and techniques, as well as
several electronic and mechanical designs employed in the Company's existing
products.

The Company owns two United States patents related to its contracts and
services work, and, jointly with UNC, has four additional United States patents
relating to compounds, pharmaceutical compositions and therapeutic methods in
connection with the Company's drug discovery program at

-13-

UNC. One additional United States application and foreign applications for all
five of the joint patents are pending.

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

Government Regulation

The manufacture and distribution of medical devices, including products
manufactured by the Company that are intended for in vitro diagnostic use, are
subject to extensive government regulation in the United States and in other
countries.

In the United States, the Food, Drug, and Cosmetic Act ("FDCA")
prohibits the marketing of most in vitro diagnostic products until they have
been cleared or approved by the FDA, a process that is time-consuming,
expensive, and uncertain. In vitro diagnostic products must be the subject of
either a premarket notification clearance (a "510(k)") or an approved premarket
approval application ("PMA"). With respect to devices reviewed through the
510(k) process, a company may not market a device for diagnostic use until an
order is issued by the FDA finding the product to be substantially equivalent
to a legally marketed device. A 510(k) submission may involve the presentation
of a substantial volume of data, including clinical data, and may require a
substantial period of review. With respect to devices reviewed through the PMA
process, a company may not market a device until FDA has approved a PMA
application, which must be supported by extensive data, including preclinical
and clinical trial data, literature, and manufacturing information to prove the
safety and effectiveness of the device.

The Company's Accurun(r) Run Controls, when marketed for diagnostic
use, have been classified by the FDA as medical devices. The FDA could,
however, require that some products be reviewed through the PMA process, which
generally involves a longer review period and the submission of more
information to FDA. There can be no assurance that the Company will obtain
regulatory approvals on a timely basis, if at all. Failure to obtain regulatory
approvals in a timely fashion or at all could have a material adverse effect on
the Company.

As of March 1, 1998, a total of nine products in the Accurun 1(r) line
and fourteen Accurun(r) single analyte controls have received 510(k) clearance
from the FDA. An additional three Accurun(r) single analyte controls have been
submitted but have not yet received FDA clearance.

Some of the Company's Accurun(r) run controls are currently marketed
"for research use only." Such products do not currently require FDA premarket
clearance or approval. The labeling of these products limits their use to
research. It is possible, however, that some purchasers of these products may
use them for diagnostic purposes despite the Company's intended use. In these
circumstances, the FDA could allege that these products should have been
cleared or approved by the FDA prior to marketing, and initiate enforcement
action against the Company, which could have a material adverse effect on the
Company. The FDA has recently issued a Draft Policy Compliance Guideline,
which, if it takes effect as written, will strictly limit the sale of products
labeled "for research use only." The Company is monitoring this situation, and
will adapt its policies as required.

BBI Source obtains 510(k) approval for all laboratory instrumentation
designed and manufactured in its Garden Grove facility.

The Company's Diagnostic Products and Laboratory Instruments product
groups are both registered as medical device manufacturers with the FDA, and
file listings of their products semi-annually. The Company's facilities in West
Bridgewater, Massachusetts for Diagnostic Products and Garden Grove, California
for Laboratory Instruments are FDA Good Manufacturing Practices

-14-

(FDA/GMP) facilities, and, as such, maintain high standards of quality in
manufacturing, testing and documentation, and implement strict GMP guidelines
governing reagent and instrument manufacturing.

Once cleared or approved, medical devices are subject to pervasive and
continuing regulation by the FDA, including, but not limited to, good
manufacturing practices ("GMP") regulations governing testing, control, and
documentation; and reporting of adverse experiences with the use of the device.
Ongoing compliance with GMP and other applicable regulatory requirements is
monitored through periodic inspections. FDA regulations require agency
clearance or approval for certain changes if they do or could affect the safety
and effectiveness of the device, including, for example, new indications for
use, labeling changes or changes in design or manufacturing methods. In
addition, both before and after clearance or approval, medical devices are
subject to certain export and import requirements under the FDCA. Product
labeling and promotional activities are subject to scrutiny by the FDA and, in
certain instances, by the Federal Trade Commission. Products may be promoted by
the Company only for their approved use. Failure to comply with these and other
regulatory requirements can result, among other consequences, in failure to
obtain premarket approvals, withdrawal of approvals, total or partial
suspension of product distribution, injunctions, civil penalties, recall or
seizures of products and criminal prosecution.

The Company believes that its Quality Control Panels are not regulated
by the FDA because they are not intended for diagnostic purposes. The Company
believes that its Diagnostic Components, which are components of in vitro
diagnostic products, may be subject to certain regulatory requirements under
the FDCA and other laws administered by the FDA, but do not require that the
Company obtain a premarket approval or clearance. There can be no assurance,
however, that the FDA would agree or that the FDA will not adopt a different
interpretation of the FDCA or other laws it administers, which could have a
material adverse effect on the Company.

The Company's Diagnostic Products and Laboratory Instruments groups are
both ISO9001 certified, with registration by TUV Rheinland. The Laboratory
Instrument group is also certified to EN46001, a set of supplementary
requirements applicable to their products.

Laws and regulations affecting some of the Company's products are in
effect in many of the countries in which the Company markets or intends to
market its products. These requirements vary from country to country. Member
states of the European Economic Area (which is composed of the European Union
members and the European Free Trade Association members) are in the process of
adopting various product and service "Directives" to address essential health,
safety, and environmental requirements associated with the subject products and
services. The "Directives" cover both quality system requirements (ISO Series
9000 Standards and the EN46001 Requirements) and product and marketing related
requirements. In addition, some jurisdictions have requirements related to
marketing of the Company's products. There can be no assurance that the Company
will be able to obtain any regulatory approvals required to market its products
on a timely basis, or at all. Delays in receipt of, or failure to receive such
approvals, or the failure to comply with regulatory requirements in these
countries or states could lead to compliance action, which could have a
material adverse effect on the Company's business, financial condition, or
results of operations.

The Company's service-related business (clinical trials, infectious
disease testing, and contract research) is subject to other national and local
requirements. The Company's facilities are subject to review, inspection,
licensure or accreditation by some states, national professional organizations
(College of American Pathologists), and other national regulatory agencies
(Health Care Financing Administration). Studies to evaluate the safety or
effectiveness of FDA regulated products (primarily human and animal drugs or
biologics) must also be conducted in conformance with relevant FDA
requirements, including Good Laboratory Practice ("GLP") regulations,
investigational new drug or device regulations, Institutional Review Board
("IRB") regulations and informed consent regulations.

-15-

The Clinical Laboratory Improvement Amendments of 1988 ("CLIA")
prohibits laboratories from performing in vitro tests for the purpose of
providing information for the diagnosis, prevention or treatment of any disease
or impairment of, or the assessment of, the health of human beings unless there
is in effect for such laboratories a certificate issued by the US Department of
Health and Human Services ("HHS") applicable to the category of examination or
procedure performed.

The Company currently holds permits issued by HHS (CLIA license),
Centers for Disease Control and Prevention (Importation of Etiological Agents
or Vectors of Human Diseases), the US Department of Agriculture (Importation
and Transportation of Controlled Materials and Organisms and Vectors) and the
US Nuclear Regulatory Commission (in vitro testing with byproduct material
under general license, covering the use of certain radioimmunoassay test
methods).

The Company is also subject to government regulation under the Clean
Water Act, the Toxic Substances Control Act, the Resource Conservation and
Recovery Act, the Atomic Energy Act, and other national, state and local
restrictions relating to the use and disposal of biohazardous, radioactive and
other hazardous substances and wastes. The Company is an exempt small quantity
generator of hazardous waste and has a US Environmental Protection Agency
identification number. The Company is also registered with the US Nuclear
Regulatory Commission for use of certain radioactive materials. The Company is
also subject to various state regulatory requirements governing the handling of
and disposal of biohazardous, radioactive and hazardous wastes. The Company has
never been a party to any environmental proceeding.

Internationally, some of the Company's products are subject to
additional regulatory requirements, which vary significantly from country to
country. Each country in which the Company's products and services are offered
must be evaluated independently to determine the country's particular
requirements. In foreign countries, the Company's distributors are generally
responsible for obtaining any required government consents.

Employees

As of December 31, 1997 the Company employed 282 persons, all of whom
were located in the United States. Of these, 102 persons were employed by the
West Bridgewater, Massachusetts company, 65 by the New Britain, Connecticut
company, 48 by the Gaithersburg, Maryland company, and 67 by the Garden Grove,
California company. None of the Company's employees is covered by a collective
bargaining agreement. The Company believes that it has a satisfactory
relationship with its employees.

(1) Effective July 1, 1997, the Company acquired the business and net assets of
Source Scientific, Inc. for $1,994,000 which increased 1997 revenues by
$2,608,000.

(2) On June 30, 1993, the Company exercised its option to pre-pay the
acquisition note in connection with the 1992 purchase of BBI Biotech at a
substantial discount from the balance due, resulting in an extraordinary
gain of $50,000 net taxes of $33,000. The 1993 net income per share before
such extraordinary gain was $0.04.

(3) Due to a modification of its maturity date, the Company's demand line of
credit with an outstanding amount of $1,895,000 as of December 31, 1993,
has been presented as part of long-term debt (and excluded from current
liabilities in calculating working capital) for 1993. This change was made
to be consistent with its reclassification to long-term debt in 1994 and
1995.

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

Overview

The Company generates revenue from products and services provided
primarily to the in vitro diagnostic infectious disease industry. There are two
broad product classes: Diagnostic Products and Laboratory Instruments.
Diagnostic Products consist of three groups: Quality Control Panels, Accurun(r)
Run Controls and Diagnostic Components. Services consist of Specialty Clinical
Laboratory Testing, Contract Research, Clinical Trials, Laboratory
Instrumentation Services, and Drug Screening. In the five full years since the
Company's acquisition of BBI Biotech Research Laboratories ("BBI Biotech") and
BBI Clinical Laboratories, Inc. ("BBICL"), the Company has experienced a shift
in revenue mix towards increased product sales, as product revenue as a
percentage of total revenue increased from 43.1% in 1993 to 52.5% in 1997, with
a corresponding decrease in the percentage of total revenue provided by
services.

The Company's gross profit margin increased from 33.9% in 1993 to 41.6%
in 1997 principally as a result of the increased percentage of higher margin
product revenues. Within products, the Company's Quality Control Products
(Accurun(r) Run Controls and Quality Control Panels) have higher margins than
the Company's Laboratory Instruments and Diagnostic Components. Within
services, Contract Research gross margins are lower than other services.
However, such contracts enable the Company to maintain certain scientific staff
and capability that it might otherwise not be able to afford. The Company
intends to continue to concentrate on the growth in sales of its Quality
Control Products.

Historically, the Company's results of operations have been subject to
quarterly fluctuations due to a variety of factors, including customer
purchasing patterns, primarily driven by end-of-year expenditures, and seasonal
demand during the summer months for certain laboratory testing services. In
particular, the Company's sales of its Quality Control Products and Diagnostic
Components typically have been highest in the fourth quarter and lowest in the
first quarter of each fiscal year, whereas Specialty Clinical Laboratory
Testing has generally reached a seasonal peak during the third quarter,
coinciding with the peak incidence of Lyme Disease. Research Contracts are
generally for large dollar amounts spread over a one or two year period, and
upon completion, frequently do not have renewal phases. As a result they can
cause large fluctuations in revenue and net income. In addition to staff
dedicated to internal research and development, certain of the Company's
technical staff work on both Contract Research for customers and Company
sponsored research and development. The allocation of certain technical staff
to such projects depends on the volume of Contract Research. As a result,
research and development expenditures fluctuate due to increases or decreases
in Contract Research.

To develop new Quality Control Products and support increased sales,
the Company hired additional research and development staff in the second half
of 1995 and sales and marketing staff in 1996 and 1997. The Company intends to
continue to add staff to these departments but at a reduced rate. General and
administrative expenses are not expected to increase at the same rate, as the
Company has already incurred significant infrastructure expenses.

The Company does not have any foreign operations. However, the Company
does have significant export sales in Europe, the Pacific Rim countries and
Canada to agents under distribution agreements, as well as directly to test kit
manufacturers. All sales are denominated in US dollars. Export sales for the
years ended December 31, 1995, 1996, and 1997 were $3.4 million, $4.3 million,
and $5.2 million, respectively. The Company expects that export sales will
continue to be a significant source of revenue and operating income.

Years Ended December 31, 1997 and 1996

The most significant event in 1997 effecting comparability of results
with 1996 was the acquisition of the business of Source Scientific, Inc.
effective July 1, 1997. The acquisition was completed by a wholly owned
subsidiary of the Company, BBI Source Scientific, Inc., ("BBI Source") and was
accounted for as an asset purchase. This effected every line of the income
statement.

Total revenue increased 43.8%, or $6,790,000, to $22,299,000 in 1997
from $15,509,000 in 1996. The increase in revenue was the result of a 38.3%
increase in product revenue of $3,241,000 to $11,711,000 from $8,470,000, and a
50.4% increase in service revenue of $3,549,000 to $10,588,000 from $7,039,000
in 1996. Approximately $1,416,000 of the product increase was attributable to
the inclusion of BBI Source for the first time, and the balance of the increase
was a result of a 34.0% increase in sales of Quality Control Products,
particularly Accurun(r) from a higher volume of both new and existing products,
offset in part by price decreases. Service revenue included $1,192,000 from
inclusion of BBI Source, a 49.1% increase in contract research revenue as a
result of new contracts, and a 32.6% increase in specialty clinical laboratory
testing revenue as the Company's HIV PCR test introduced in September 1996, was
offered for a full year in 1997. Overall for both products and services, prices
declined slightly in 1997 versus 1996. In summary, even after excluding BBI
Source, the Company's total revenue increased 27.0% in 1997 compared to 1996
with a 21.5% increase in product revenue, and a 33.5% increase in service
revenue on strong volume performance by Quality Control Products, contract
research, and specialty clinical laboratory testing.

Gross profit increased 45.1%, or $2,886,000, to $9,287,000 for 1997
from $6,401,000 in 1996. Product gross profit increased 40.8%, or $1,720,000,
to $5,938,000 in 1997 from $4,218,000 in 1996 and product gross profit margin
increased to 50.7% in 1997 from 49.8%. The products gross margin increase was a
result of a favorable shift in product mix towards Accurun sales and overall
volume increase, thereby spreading fixed costs over a larger base, and despite
a lower gross profit margin in BBI Source's instrument sales. Services gross
profit increased 53.5%, or $1,167,000, to $3,350,000 in 1997 from $2,183,000 in
1996 as the testing volume increased at a faster rate than laboratory
headcount, thereby

-22-

causing the services gross profit margin to increase to 31.6% in 1997 from
31.0% in 1996. BBI Source's service gross profit margin was slightly higher
than the Company average, which is expected to continue.

Research and development expenditures increased 64.6%, or $514,000, to
$1,311,000 in 1997 from $797,000 in 1996. The increase resulted primarily from
new Laboratory Instrument development activities at BBI Source, as well as
increased development expenditures for Accurun(r), molecular and immunological
Run Controls, and specialized molecular assays.

Selling and marketing expenses increased 48.1%, or $1,053,000, to
$3,241,000 in 1997 from $2,188,000 in 1996. The increase was attributable
primarily to an eleven person expansion of the TQS sales, marketing, and
technical support staff and related increased trade show and travel expenses.
In addition, the inclusion of BBI Source added $167,000 of expense to this
category.

General and administrative costs increased 39.2%, or $942,000, to
$3,343,000 in 1997 from $2,401,000 in 1996. This increase was attributable
primarily to: the addition of a Director of Human Resources and wide area
network systems analyst; higher expenditures for accounting and legal
professionals and investor relations activities in our first full year as a
public company; increased travel associated with the BBI Source acquisition;
and non-recurring moving costs of $40,000 associated with moving BBI Biotech
Research Laboratories to a new facility in Gaithersburg Maryland. These
increases were partially offset by a lower provision for doubtful accounts as a
result of improved accounts receivable collections from patients at the
Company's clinical reference testing laboratory. In addition, the inclusion of
BBI Source added $442,000 of expense to this category.

Operating income increased 37.1%, or $377,000, to $1,392,000 in 1997
from $1,015,000 in 1996. This increase was primarily a result of continued
strong performance in the Company's Quality Control Products business and
clinic reference testing laboratory, partially offset by a loss at BBI Source
of $189,000.

The Company had net interest income of $283,000 in 1997 versus net
interest expense of ($213,000) in 1996 as substantially all of the Company's
debt was repaid in November 1996 with a portion of the proceeds from its IPO.
The Company had positive cash balances to invest for all of 1997.

Net income increased 108.9%, or $524,000, to $1,005,000 in 1997 from
$481,000 in 1996. Of this increase, 43% was attributable to higher operating
income, and the balance was due to the shift from net interest expense in 1996
to net interest income in 1997. Diluted earnings per share increased 50% to
$0.21 for 1997 versus $0.14 in 1996. This increase was achieved even though
weighted average diluted shares outstanding increased 43%. Basic earnings per
share increased 35% to $0.23 for 1997 versus $0.17 in 1996.

Years Ended December 31, 1996 and 1995

Total revenue increased 26.4%, or $3,239,000, to $15,509,000 in 1996
from $12,271,000 in 1995. The increase in revenue was the result of a 27.9%
increase in product revenue of $1,848,000 to $8,470,000 from $6,622,000, and a
24.6% increase in service revenue of $1,390,000 to $7,039,000 from $5,649,000
in 1995. The increase in product revenue was attributable to an increase in the
volume of sales of Quality Control Products, particularly Accurun. The
increase in service revenue was primarily the result of increased volume of
specialty clinical laboratory testing and a favorable mix shift towards higher
priced molecular testing, and the impact of two new research contracts. This
was partially offset by lower volume of clinical trial services.

Gross profit increased 41.0%, or $1,862,000, to $6,400,599 for 1996
from $4,539,000 in 1995. Products gross profit increased 38.0%, or $1,160,000,
to $4,217,000 in 1996 from $3,057,000 in 1995 and products gross profit margin
increased to 49.8% in 1996 from 46.2%. The products gross margin increase was a
result of a favorable mix shift towards Accurun sales. Services gross profit
increased 47.3%, or $701,000, to $2,183,000 in 1996 from $1,481,000 in 1995 as
the testing volume increased at a

-23-

faster rate than laboratory headcount increased, and thereby caused the
services gross profit margin to increase to 31.0% in 1996 from 26.2% in 1995.

Research and development expenditures increased 112.1%, or $421,000, to
$797,000 in 1996 from $376,000 in 1995. The increase resulted from increased
costs of personnel hired in the second half of 1995 to step-up the rate of new
product introductions, and increased research project expenditures. Development
projects included Accurun(r), molecular and immunological Run Controls,
specialized molecular assays, and expenditures related to the Company's drug
discovery program.

Selling and marketing expenses increased 63.3%, or $848,000, to
$2,188,000 in 1996 from $1,340,000 in 1995. The increase was attributable
primarily to additional sales and marketing staff and overhead; increased
advertising, promotion, trade show and travel expenses due to the commencement
of the Company's "Total Quality System" (TQS) marketing campaign; and costs
associated with participation by the Company's Specialty Clinical Laboratory in
the Roche Diagnostics' Amplicor( Access program in connection with Roche's
launch of their new FDA approved HIV PCR test kit. The Amplicor( kit is
primarily used to monitor the HIV viral load (level) in patients prior to and
during drug therapy.

General and administrative costs increased 3.7%, or $85,000, to
$2,401,000 in 1996 from $2,316,000 in 1995. This increase was attributable
primarily to additional staffing in support of Company growth and higher
reserve provisions for doubtful accounts associated with the increased volume
of revenue related to testing in situations in which payment to the Company
depends on collecting from the patient rather than a healthcare institution.

Operating income increased 100.0%, or $507,000, to $1,015,000 in 1996
from $508,000 in 1995. This increase was primarily a result of a very strong
performance in the Company's Quality Control Products business and clinic
reference testing laboratory.

Net interest expense decreased 36.6%, or $123,000, to $213,000 in 1996
from $336,000 in 1995, as the proceeds from the Company's initial public
offering were used to pay down almost all debt in early November, and the
remaining amount invested in short term, investment grade securities.

Net income increased 367.2%, or $378,000, to $481,000 in 1996 from
$103,000 in 1995. Diluted earnings per share increased 325% to $0.14 for 1996
versus $0.03 in 1995. Weighted average diluted shares outstanding only
increased 10% in 1996 over 1995 as the Company's shares issued in connection
with its IPO were outstanding for only two months in 1996. Basic earnings per
share increased 312% to $0.17 for 1996 versus $0.04 in 1995.

Liquidity and Capital Resources

At December 31, 1997, the Company had cash and cash equivalents of
approximately $2,772,000 and working capital of $9,633,000. Trade accounts
receivable increased $2,143,000 or 62.7%, primarily from the inclusion of BBI
Source in the year end balance sheet for the first time, and significant growth
in fourth quarter revenue in 1997. Inventory increased $1,723,000 or 41.2%,
again primarily due to the inclusion of BBI Source for the first time, and the
addition of 39 new products to inventory.

On October 31, 1996, the Company's Common Stock commenced trading on the
NASDAQ as a result of completing the initial public offering of its common
stock ("IPO"), selling 1,600,000 shares at $8.50 per share. Net proceeds
received after underwriting discounts, commissions and offering costs was
approximately $11,633,000. On November 5, 1996, the Company repaid
substantially all of its outstanding bank debt which totaled approximately $3.9
million.

The Company has financed its operations to date through cash flow from
operations, borrowings from banks and sales of equity. The Company expects its
cash flow and cash position to meet existing operational needs, although its
revolving line of credit will be available as needed for working capital.

-24-


Net cash provided by operations for 1997 was $727,000 as compared to
$1,460,000 in 1996. As discussed above, this decrease in cash flow was
primarily attributable to carrying additional accounts receivable and inventory
as of year end. This was partially offset by an increase in deferred revenue
from a payment of $331,000 under a research contract for future clinical trial
services, and a net increase in accounts payable and accrued expenses of
$696,000. Also benefiting net cash from operations for 1997 was a $290,000
reduction in current federal tax liability as a result of non-qualified stock
option exercises. Cash flow used in operations in 1995 was $29,000 as working
capital needs due to sales growth exceeded cash generated from net income
adjusted by non cash expenses.

Cash used in investing activities for 1997, 1996 and 1995 amounted to
$5,396,000, $1,412,000, and $1,320,000, respectively. In addition to normal
capital expenditures, four items accounted for most of the 1997 investing
activities. First, the Company exercised its option to purchase an additional
165,000 shares of BioSeq, Inc. stock at an aggregate cost of $750,000, thereby
increasing its ownership of BioSeq to 19.9%. Second, in May 1997, the Company's
BBI Biotech subsidiary signed a ten year lease for new laboratory space in
Gaithersburg, Maryland and spent $566,000 on leasehold improvements for new
laboratory space for its contract research and product development activities.
Third, the expansion and renovation of its Diagnostic Products manufacturing
facility in West Bridgewater, Massachusetts commenced construction and
approximately $920,000 was expended as the project is now over two-thirds
complete. Finally, effective on July 1, 1997, the Company completed the
acquisition of the business and net assets of Source Scientific, Inc. at a
purchase price of $1,994,000 including acquisition costs. The Company has
accounted for the acquisition as an asset purchase, and is amortizing goodwill
of approximately $2.2 million over 15 years. See Note 2 to the Company's Notes
to Consolidated Financial Statements in Item 8 hereunder. The cash used in
investing activities in 1996 included the initial investment in BioSeq, Inc. of
$732,500, while 1995 included the purchase of the Company's West Bridgewater
facility for $806,000.

During 1997, net cash generated from financing activities included
$300,000 from the exercise of warrants, and $182,000 from exercising stock
options. Also in 1997, $1,124,000 was used to pay down debt acquired in
connection with the Source acquisition. In 1996, net cash generated from
common stock issued, including the IPO, approximated $12,600,000. This was
used to pay down net debt of $4,577,000. Net cash provided by borrowings for
1995 amounted to $1,240,000, and net proceeds from the sale of Common Stock for
the same period was approximately $176,000. The proceeds of such debt were used
for working capital, to acquire the West Bridgewater property and to purchase
capital equipment.

In 1997, 1996 and 1995 capital expenditures amounted to $2,613,000,
$669,000, and $1,316,000, respectively. The 1997 expenditures included both
the Massachusetts and Maryland facility improvement, and the 1995 expenditures
related to the purchase of the West Bridgewater facility, all as discussed
above.

On April 26, 1996 the Company entered into a new five year distribution
agreement with Kyowa Medex, Co., Ltd., a foreign distributor, extending a six
year old relationship. Simultaneously, Kyowa purchased 117,647 shares of the
Company's Common Stock at a price of $8.50 per share. Under the distribution
agreement, Kyowa has been granted an exclusive right to sell and distribute
the Company's products in Japan and to continue to purchase product from the
Company at a discount. In return, Kyowa is obligated to achieve certain
minimum sales levels, provide market, sales and regulatory information, and has
agreed not to compete with the Company.

On March 9, 1998, the Company announced plans to modify a previously
announced 3-year contract with ABX Hematology, Inc. ("ABX") and its parent
company, ABX Hematologie, SA (France). Under the contract, the Company provided
technical, customer and field services for instruments sold by ABX in the
United States. Under the modified agreement, individual customer service
contracts will be assigned to ABX and ABX will assume responsibility for its
United States instruments. The Company will provide certain consulting services
through March 1999 to assist ABX in establishing a sales, customer service,
technical support, and field service operation in the United States for its
hematology

-25-

instrument and reagent business. In addition, the Company has agreed to allow
ABX to occupy space at its California facility during the period of the
agreement. The Company's personnel associated with this contract, included the
nationwide field service organization and hotline technical support, will be
offered employment by ABX.

The Company is accounting for its investment in BioSeq on the
cost-basis in accordance with the provisions of APB 18 since its cumulative
investment is less than 20% of the equity of BioSeq and the Company does not
exert significant influence or control. BioSeq needs to obtain additional
financing in 1998 to continue operations and there can be no assurances that
any such financing will be available upon acceptable terms. Due to the
uncertainty of technology based development stage enterprises, the Company
performs a periodic analysis of the investment to determine whether the
carrying value of its investment in BioSeq has been other than temporarily
impaired. In performing the analysis of its investment in BioSeq for the
current year, management considered BioSeq's positive factors including its
technology, patent positions, business prospects, and the possibility of
raising capital and achieving financial success; as well as its negative cash
flow and net worth, and limited cash and other resources, and failure to date
to raise significant capital independent of the Company. Management has
concluded that its investment has not been other than temporarily impaired, if
at all. If it is subsequently determined to be impaired, the Company will
adjust the carrying value of its investment by taking a charge to earnings
which could amount to the full value of its $1,482,500 investment as of
December 31, 1997. See also Note 14 relating to the Company's $600,000
purchase of certain technology rights from BioSeq.

The Company anticipates capital expenditures to begin slowing down in
1998 as most of the Maryland and approximately two-thirds of the Massachusetts
projects have been completed. The Company believes that existing cash balances,
the borrowing capacity available under the revolving line of credit, and cash
generated from operations are sufficient to fund operations and anticipated
capital expenditures for the foreseeable future. Except for purchase orders in
connection with the manufacturing expansion, there were no material financial
commitments for capital expenditures as of December 31, 1997.

Year 2000 Computer Systems Compliance

Concerns have been widely expressed regarding the inability of certain
computer programs to process date information beyond year 1999. These concerns
focus on the impact of the Year 2000 problem on business operations and the
potential costs associated with identifying and addressing the problem. The
Company is in the process of evaluating and taking steps to deal with the
potential impact of this problem in areas under its control, including its
products and sources of supply, as well as its operations management,
administration and financial systems.

Based on its review to date, the Company believes that its products are
"Year 2000 compliant." The Company plans to correct or replace its
administrative and business systems in time to avoid material problems. The
Company has confirmed with existing software vendors that Year 2000 compliant
versions either exist or will be available to upgrade or replace its operations
management, administrative and financial systems. Where it believes that a
particular supplier's situation poses unacceptable risks, the Company plans to
identify an alternative source.

Based upon its review, the Company does not believe that the Year 2000
problem will have a material adverse affect on the Company. However, there can
be no assurances that failure to comply with Year 2000 by parties outside its
control will not have a material adverse affect on the Company.
