ITEM 1.  BUSINESS

     The Company is a leading worldwide provider of specialty human antibodies
and other blood-related products and services to major healthcare companies. The
Company's services, including donor recruitment, donor management and clinical
testing services, enable the Company to provide value-added specialty antibodies
that are used as the active ingredients in therapeutic products for the
treatment and management of such medical indications as Rh incompatibility in
newborns, rabies and hepatitis and in diagnostic products such as blood typing
reagents and diagnostic test kits. In addition, the Company collects source
plasma containing non-specialty antibodies from which a number of products,
primarily intravenous immune globulin (IVIG), a product containing a broad
spectrum of antibodies used in the treatment of a wide variety of medical
indications, are derived. Owing in part to increasing margin pressures and the
inability of the Company to pass increased costs on to its customers, the
Company is currently performing a strategic review of its non-specialty
operations, and is in discussions which could result in the divestiture of all
or a portion of its 47 non-specialty donor centers. As of March 24, 2000, the
Company conducted its operations through a national network of 64 donor centers
and through laboratories located in the United States and the United Kingdom.
The Company also operates two monoclonal antibody manufacturing facilities in
Scotland. On December 29, 1998, the Company purchased substantially all of the
assets of the Pentex Blood Proteins business of Bayer Corporation ("Pentex",
renamed "Serologicals Proteins" by the Company). Located in Kankakee, Illinois,
Serologicals Proteins supplies a broad line of purified animal and human blood
proteins to the diagnostic and biopharmaceutical industries.

     For management purposes, the operations of the Company's subsidiaries are
organized into two primary operating segments, Therapeutic Products and
Diagnostic Products. These segments are based primarily on the differing nature
of the ultimate end use of the Company's products, the differing production and
other value-added processes performed by the Company with respect to the
products and, to a lesser extent, the differing customer bases to which each
reportable segment sells its products.

     The activities of the Therapeutic Products segment primarily include the
sale of specialty and non-specialty human antibodies collected at the Company's
network of donor centers and used as the active ingredients in therapeutic
products for the treatment and management of various diseases. The activities of
the Diagnostic Products segment include the Company's monoclonal antibody
production facilities and certain human-sourced, polyclonal antibodies. The
Diagnostic Products segment also includes the activities of the Company's
protein fractionation facility located in Kankakee, Illinois. The antibodies and
other proteins
                                        3
<PAGE>   6

provided by the Diagnostic Products segment are used in diagnostic products such
as blood typing reagents and diagnostic test kits and as nutrient additives in
biotechnology products.

INDUSTRY OVERVIEW

     The human blood products and services industry encompasses a number of
markets, with products ranging from whole blood, which is used for direct
transfusions, to blood components, such as source plasma, specialty and
non-specialty antibodies found in source plasma and other specialty biologic
components. Source plasma, the clear liquid portion of blood characterized by
non-specific concentrations of antibodies, is used to manufacture many products
that treat a variety of medical indications. Antibodies are soluble components
contained in plasma which are produced by the immune system to fight specific
diseases. Other derivative products of source plasma include albumin, used to
treat shock and burn patients, and clotting factors such as Factor VIII
Concentrate and Factor IX Concentrate, used primarily by hemophiliac patients.

     The therapeutics industry is generally divided into two distinct sectors.
The largest sector of the industry is comprised of non-profit organizations,
such as the American Red Cross and community blood banks, which supply whole
blood and other transfusible products to hospitals. Conversely, the commercial
sector of the industry is focused primarily on supplying source plasma,
specialty and non-specialty antibodies and specialty biologic components to
healthcare companies which further process these components into therapeutic and
diagnostic products.

     The therapeutic segment of the commercial sector includes products
consisting of specialty antibodies and cells, as well as non-specific, or
non-specialty, antibodies and source plasma. Specialty antibodies are typically
used to manufacture products for treating persons exposed to, or at risk of,
contracting a specific disease. Specialty antibodies used for therapeutic
purposes range from those used to treat medical indications such as tetanus and
rabies, which the Company believes generally sell for approximately $90 to $250
per liter, to high-end products such as anti-D, an antibody used to treat Rh
incompatibility in newborns and anti-hepatitis, which the Company believes
generally sell for approximately $400 to $600 per liter. By comparison, the
Company believes the average industry gross price of source plasma, from which
IVIG and other products are derived, is approximately $87 to $94 per liter.

     Antibodies, both human sourced as well as those in monoclonal form, are
also used in the manufacture of diagnostic products used to screen patients for
prior exposure to a specific disease or to determine blood type. Polyclonal and
monoclonal antibodies used in diagnostic products such as blood typing reagents
and diagnostic test kits generally sell for $0.95 per milliliter to $8.00 per
milliliter, with some rare antibodies selling for as high as $20.00 per
milliliter.

     The Company believes that there are a number of factors increasing the
demand for antibodies and antibody-based products in general. In the treatment
of certain diseases such as rabies and Rh incompatibility in newborns,
antibody-based products are recognized as the only generally accepted treatment
or prevention for such diseases. In addition, medical and scientific advances
are increasing the demand for antibodies for new indications and improved
therapies. For example, while there are only six FDA-approved uses for IVIG, the
Company believes there are approximately 60 medical conditions for which it is
currently being used or clinically examined as a treatment. The Company also
believes that cost containment in healthcare is spurring the demand for
alternatives to antibiotics and vaccines, such as the use of antibody-based
products for disease management. Additionally, increasing regulation and
concerns relating to blood safety are causing demand for a broader array of
antibody-based diagnostic tests used to evaluate blood samples. The demand for
more diverse diagnostic tests is also increasing as world population migration
is spreading diseases, which were once confined to specific geographic areas.
The Company also believes that the aging of the U.S. population is increasing
the demand for antibody-based products that are as efficacious as, but less
toxic than, many alternative treatment regimens.

     The Company believes that there are a number of factors that are limiting
the supply of commercially available human antibodies. The supply of antibodies
has been adversely affected by the more rigorous screening procedures required
by regulatory authorities, in particular the FDA and certain German regulatory
bodies, industry trade organizations and manufacturers of the various end
products. These procedures, which
                                        4
<PAGE>   7

include a more extensive investigation into a donor's background, new tests to
detect the presence of disease-causing organisms and other limitations on donors
such as age restrictions, have disqualified numerous potential donors and
discouraged other donors who may be reluctant to undergo the screening
procedures. Furthermore, the Company believes that, owing in part to the general
strength of the national economy, the financial incentives provided to donors
may be less attractive as compensation for their time, further decreasing the
pool of potential donors. Also, as customers require increasingly higher
concentrations of specialty antibodies, the qualified pool of donors is further
reduced. These customer requirements have resulted in an increasing need to
boost the concentration of specialty antibodies in donors through vaccination or
immunization. Furthermore, the length of time required to be granted regulatory
licenses for donor centers, testing facilities and biological products is
significant.

     Recently, the therapeutics industry has been experiencing critical
shortages of certain end products, most notably IVIG. The Company believes that
in addition to the factors discussed above, this shortage has been caused by
several company-specific manufacturing, regulatory or other issues facing the
manufacturers of this product, as well as by recalls of product manufactured
with antibodies obtained from donors who were subsequently discovered to have
had new variant Creutzfeld-Jakob disease ("nvCJD"). See "Government and Industry
Regulation" and "Management's Discussion and Analysis of Financial Condition and
Results of Operations-Overview."

     In contradiction to these supply and demand dynamics, margins on the
Company's, and in its opinion, other industry participants', non-specialty
antibody business continue to be under significant pressure, as the Company has
generally been unable to pass on all increased costs to its customers. The
Company believes this is the result of decreasing margins at the customer level
on other products obtained from source plasma, such as albumin and
anti-hemophiliac factors, as recombinant products have increased in use and have
in part reduced the need for their human-derived counterparts.

     In addition to the demand and supply factors discussed above, the industry
continues to experience a number of other trends. One such trend is the movement
by healthcare companies towards obtaining antibodies and other biologic products
and services from a fewer number of suppliers who can supply a wider array of
products and services. The resulting enhanced relationships between healthcare
companies and these suppliers have resulted in an increased tendency of some
major healthcare companies to outsource essential complex regulatory, testing
and specialized manufacturing activities. In addition, the increased regulatory
environment, as well as the increasing preference of customers for value-added
services, requires suppliers to have a high level of expertise and capital
resources.

OPERATIONS

     As of March 24, 2000, the Company conducted its operations through a
national network of 64 donor centers laboratories located in the United States
and the United Kingdom, two monoclonal production facilities in Scotland and a
purified blood proteins fractionation facility in Kankakee, IL.

THERAPEUTIC PRODUCTS

     Donor Recruitment.  The Company obtains the significant majority of its
specialty antibodies from donors with high concentrations of the antibodies
sought. The Company maintains an active communications network with medical
professionals and healthcare organizations nationwide to assist in identifying
these donors. The majority of the Company's 17 specialty donor centers are
strategically located on or near medical campuses, enhancing the Company's
ability to source specialty antibodies from medical community referrals. In
addition, the Company is able to identify and react rapidly to disease outbreaks
in order to recruit suitable donors for specialty antibodies created by such
specific diseases. The Company actively seeks to maintain and replenish its
donor base for its specialty therapeutic and diagnostic products and maintains
an ongoing program to recruit donors and make medical professionals aware of its
capabilities and needs.

     One trend that the Company has experienced in recent years is an increased
difficulty in recruiting and retaining donors of non-specialty antibodies. The
Company believes that owing in part to the general strength of the national
economy, the financial incentives provided to these donors may be less
attractive as
                                        5
<PAGE>   8

compensation for their time. While the Company continues to pursue various
alternatives to increase production at its non-specialty donor centers, there
can be no assurance that such efforts will be successful, or that any adverse
effect from these trends will not be material.

     Donor Screening and Product Collection.  Each donor candidate undergoes a
process that includes an explanation of the donation procedure and how the
antibodies they are donating are subsequently used, extensive physiological and
biological screening, a physical examination and the collection of test samples.
In addition, donors of specialty antibodies undergo further qualification
profiling. Once a candidate is accepted as a donor, the Company may collect
antibodies from the donor at its donor centers through an FDA-approved
collection procedure known as plasmapheresis, which lasts between 40 and 60
minutes and is very similar to donating blood. However, since red blood cells
are returned to the donor by means of centrifugation, individuals may donate as
frequently as twice per week. Each donation is quarantined at the donor center
while test samples are sent to the Company's central testing laboratory
(specialty antibodies), or its customers' or other third party laboratories
(non-specialty antibodies), for FDA-mandated viral marker screening tests (e.g.,
hepatitis, HIV, etc.) and in the case of specialty antibodies, characterization
(i.e., special analytical tests to identify and measure the quality and
concentration of the targeted antibodies). Furthermore, voluntary industry
standards require that each first time donor's ("Applicant Donor") donation be
quarantined until such time that a second donation is received from the
Applicant Donor and appropriate test results are obtained on both donations. If
a second donation is not received from the Applicant Donor within six months,
the initial donation must be destroyed. Once these two donations and their test
results are complete and acceptable, the Applicant Donor becomes a "qualified
donor" and all future donations are generally available for shipment once the
mandated tests have been completed.

     Product Characterization.  The Company characterizes the specialty
antibodies it collects to ensure that the concentration of antibodies meets
customer specifications. The Company maintains extensive data on each of its
donors for both regulatory compliance and quality assurance. This database
enhances the Company's donor tracking and monitoring capabilities, which help
assure the quality of the antibodies for its customers. The ability to
accurately characterize and trace the source of antibodies adds value to the
products for the customer by replacing steps the customer might otherwise have
to perform.

     Donor Management.  Through communication and incentive programs and an
emphasis on customer service, the Company encourages full and continuing
participation by its donors. As an integral part of donor management, the
Company's staff continually communicates with donors to reinforce their
commitment. The Company has personnel and programs designed to make each visit
to the donor center a smooth, comfortable and safe experience. The Company's
expertise in donor management has enabled it to retain many donors for years of
repeated, regular donations, thereby enhancing the Company's profitability. The
Company's specialty donors typically donate once or twice per week, with many
having continued as donors for ten years or greater. A significant portion of
the Company's rare specialty antibody donors have entered into contracts with
the Company pursuant to which they have agreed to donate exclusively to the
Company for a three-year period.

     Immunization.  In response to customer demands for higher quality products
and in part due to the decreasing population of individuals with certain
naturally occurring antibodies, the Company's specialty donor centers are
actively involved in the immunization of the majority their specialty antibody
donors. Immunization is the use of FDA-approved vaccines to stimulate the
development or heighten the concentration of already existing specialty
antibodies in the donor. Although vaccines to conduct immunization for several
of the Company's products are commercially available, the Company believes it
has a competitive advantage through its existing inventory of, and ongoing
ability to produce, its own proprietary FDA-approved vaccine to produce anti-D
antibodies in donors. In some cases, antibody-producing white cells are also
collected from immunized donors and used to develop monoclonal products for
diagnostic use.

DIAGNOSTIC PRODUCTS

     Monoclonal Antibody Production.  In addition to collecting antibodies from
its donors, the Company, through its Serologicals, Ltd. subsidiary, formerly
known as Bioscot, Ltd., produces monoclonal, or cloned, antibodies from over 45
cell lines. The Company's FDA-licensed monoclonal manufacturing facilities in

                                        6
<PAGE>   9

Edinburgh and Livingston, Scotland produce monoclonal antibodies from cells
derived through the Company's donor network or acquired from other laboratories.
Currently, all monoclonal antibodies manufactured by the Company are used in
diagnostic products such as blood typing reagents. Through this monoclonal
manufacturing capability, the Company has been able to introduce additional,
second generation, human monoclonal products and continues to expand the sale of
its finished products outside the United States, such as its value-added line of
OEM and branded blood typing reagents. The Company also produces at its
monoclonal antibody facilities additional companion products to its monoclonal
blood typing range. These include reagent red cells, enzymes, and diluents that
are used in blood typing laboratories.

     Blood Protein Fractionation.  The Company, through its manufacturing
facility in Kankakee, Illinois, isolates specific proteins contained primarily
in animal sera or plasma through specialized manufacturing processes known as
protein fractionation. The Company utilizes core technologies such as organic
solvent precipitation, heat shock, molecular and microporous filtration,
ion-exchange chromatography and salt precipitation to isolate and purify major
plasma protein classes (e.g., albumin, gamma globulin, transferrin, lipoproteins
and clotting factors). The resulting blood protein product line is sold
worldwide in over 25 countries, to healthcare companies that manufacture blood
typing or other diagnostic reagents, and increasingly to biopharmaceutical
companies for use in tissue culture media.

     The primary raw material used by Serologicals Proteins, bovine serum, is
purchased almost exclusively from a single abattoir located in Illinois. During
1999, the Company entered into a long-term agreement with the supplier, pursuant
to which the Company is guaranteed certain minimum levels of serum.
Additionally, the contract provides the Company with certain rights in the event
of a change in control of this supplier. An inability of the supplier to meet
its obligations under the contract or any other material disruption in the
supply of serum could have an adverse effect on the Company.

PRODUCTS

     Through its value-added services, the Company provides antibodies and other
biologic products for use in certain therapeutic and diagnostic products
manufactured by major healthcare companies. The Company's customers generally
further process these products. The Company also sells an increasing number of
certain antibodies for blood typing reagents directly to end-users. The Company
also provides a full range of animal and human proteins that are used in
recombinant therapeutic products and in diagnostic reagents. In 1999, the
Company derived approximately 70% of its net sales from therapeutic products, a
substantial majority of which related to anti-D and non-specialty antibodies,
and approximately 29% of its net sales from diagnostic products, the majority of
which related to animal protein products for use in diagnostic reagents and as
tissue media components for use in biopharmaceutical therapeutic products and
antibodies used in blood typing reagents and diagnostic test kits. The remaining
sales were generated by miscellaneous products and services.

  Therapeutic Products

     Therapeutic end products produced by the Company's customers for whom it
supplies the majority of its antibodies include the following:

     Specialty Antibodies

          Anti-D Immune Globulin ("anti-D").  Since 1968, anti-D immune
     globulin, also known as Rh immune globulin, has been prescribed by
     obstetricians to prevent Rh incompatibility in newborns ("RhHDN"). This
     sometimes-fatal condition affecting Rh positive infants born to Rh-negative
     women is due to the incompatibility of the blood of an Rh-negative mother
     and her Rh-positive child. Anti-D immune globulin is also used in the
     treatment of Idiopathic Thrombocytopenic Purpura ("ITP") in
     immunocompromised patients. ITP, which is common in HIV positive patients,
     is a disease that is characterized by destruction of the patient's
     platelets, which, if untreated, can result in internal hemorrhaging and
     ultimately, death. This condition is estimated to affect up to 100,000
     Americans.

          The Company believes that demand for anti-D antibodies used in the
     treatment of RhHDN has generally followed the birth rate of developed
     countries. The Company believes that, on a longer-term
                                        7
<PAGE>   10

     basis, worldwide demand for anti-D antibodies could increase as its use as
     a treatment for ITP becomes more widely accepted.

          Anti-Hepatitis Immune Globulin ("anti-HBs").  The traditional use for
     anti-HBs is for the prevention of hepatitis in individuals who are at risk
     of contracting, or have had recent exposure to, the hepatitis B virus. In
     addition, anti-HBs is used for intensive treatment of liver transplant
     patients.

          Anti-Rabies Immune Globulin ("anti-rabies").  Anti-rabies immune
     globulin therapy is prescribed for individuals suspected of recent exposure
     to the rabies virus. Rabies is commonly transmitted by infectious saliva
     from the bite of a rabid animal. Anti-rabies is administered as promptly as
     possible after exposure and consists of antibodies directed against the
     live virus particles with which the patient may be infected. In the
     post-exposure treatment regimen, anti-rabies is administered in conjunction
     with a rabies vaccine, which is used to provide the patient with an
     additional active immunity to the rabies virus.

     Non-Specialty Antibodies

          Intravenous Immune Globulin ("IVIG").  IVIG is derived from source
     plasma and is comprised of a broad spectrum of antibodies. IVIG is used in
     the treatment of many medical indications, primarily for patients with
     suppressed immune systems, to help build the body's defense against
     exposure to life threatening diseases.

          Other.  Other products manufactured from source plasma collected by
     the Company include albumin, used to treat shock and burn patients, and
     anti-hemophiliac clotting factors. The Company has also on occasion
     supplied antibodies used in the treatment of respiratory syncytial virus, a
     virus affecting the respiratory tract, and cytomegalovirus, a herpes virus
     for which individuals with compromised immune systems are most at risk.

  Diagnostic Products

     The primary diagnostic products produced and sold by the Company include
the following:

          Antibodies for Blood Typing Reagents.  Blood typing reagents are used
     by blood banks and hospital transfusion services worldwide to assure
     compatibility between a recipient and a donor's blood type. Historically,
     blood typing reagents were made primarily from human-sourced, or
     polyclonal, antibodies. More recently, monoclonal antibodies have been
     developed to provide certain high quality antibodies on a consistent basis,
     and many of these are FDA approved for diagnostic purposes. The Company
     currently provides over 80 different antibodies used in the production of
     blood typing reagents that the Company believes provide it with a
     competitive advantage in this market due to the desire of customers to buy
     an entire panel of different antibodies for blood typing reagents from one
     manufacturer. The Company has recently entered into an OEM arrangement with
     a major customer and manufactures a fuller line of products for use in
     blood banks and hospitals carrying out blood transfusions. While the
     majority of antibodies sold by the Company for use in blood typing reagents
     are in monoclonal form, the Company continues to collect certain rare
     human-sourced polyclonal antibodies that are used in diagnostic products.

          Animal Blood Proteins.  Through its acquisition of Pentex, the Company
     provides a wide range of approximately 90 distinct animal protein products
     derived from five different animal species. These products, such as bovine
     serum albumin ("BSA"), are primarily supplied to healthcare companies for
     use in blood typing and other diagnostic reagents. One of the primary uses
     of bovine albumin is to enhance the detection of blood group antibodies, a
     characteristic essential for the safe transfusion of whole blood. The
     Company also provides a line of highly purified animal proteins known as
     tissue culture media components that are used by biotechnology and
     biopharmaceutical companies as nutrient additives in cell culture media.
     Examples of these media components are Bovine EX-CYTE(R), Growth
     Enhancement Media Supplement, produced through a patented manufacturing
     process, and transferrin. Many of the recombinant proteins currently used
     as therapeutic products are genetically engineered in mammalian cells. In
     order for these cells to grow and produce, they require nourishment that
     can be found from such

                                        8
<PAGE>   11

     sources as Bovine EX-CYTE(R), which is rich in cholesterol, phospholipids
     and essential fatty acids, and transferrin, a protein that provides the
     cells with the iron required for proper cellular respiration to occur.

          In order to meet current and expected demand for its line of
     EX-CYTE(R) products, during 1999 the Company completed a significant
     expansion of its protein fractionation facility in Kankakee, Illinois.
     Demand for the acquired EX-CYTE(R) product line has increased significantly
     in recent years as the success rate of genetically engineered proteins and
     other biotechnology products has increased. Furthermore, the Pentex(R)
     brand of bovine serum albumin has also seen recent growth, generally
     following the growth rate of immunodiagnostic products but more recently
     due to a decrease in production from a competitor resulting from regulatory
     issues at its manufacturing facility. The Company is currently undergoing a
     $2 million expansion of its BSA manufacturing capacity to meet the current
     and anticipated demand for this product. The BSA project is expected to be
     completed in the third quarter of 2000 and will increase total annual BSA
     capacity 30%.

          Clinical Diagnostic Antibodies.  Through its expertise in donor
     recruiting, the Company is able to locate and recruit donors who can
     provide antibodies and other biological specimens that are known to be
     positive or negative for a specific disease or infection. The Company
     provides these biological specimens for use in clinical diagnostic test kit
     controls. The diseases for which the Company sources clinical diagnostic
     antibodies include, among others, CMV, rheumatoid arthritis, toxoplasmosis,
     hepatitis and HIV. The Company's recruiting capability is complemented by
     in-house experience in the laboratory disciplines of immunohematology,
     immunology, serology and clinical chemistry to characterize human specimens
     to meet manufacturers' requirements.

PRODUCT DEVELOPMENT

     The Company is engaged in several near-term development projects designed
to enhance its existing product lines, such as the development of more efficient
techniques for the manufacture of monoclonal antibodies. The Company is also
exploring the opportunity of providing monoclonal antibodies for use in
diagnostic test kit controls using the same approach that led to the Company's
ability to commercialize monoclonal antibodies for use in blood typing reagents.

     Serologicals Proteins is also involved in several projects that it believes
will ultimately add value to its blood proteins business. Major development
projects include: the process development of the method to isolate gamma
globulin from rabbit serum, the manufacturing scale-up of a protease-free form
of bovine serum albumin, the process improvement of the procedure used to
control the polymerization of bovine serum albumin, the fatty acid enrichment of
BSA and the fractionation of albumin from new born calf serum. The Company is
also pursuing utilizing the manufacturing capabilities of the Serologicals
Proteins facility to increase production of defibrinated human plasma, currently
performed in limited quantities at its central testing laboratory in Atlanta,
Georgia.

MARKETING AND CUSTOMERS

     The Company markets its products to over 200 customers worldwide, including
many major healthcare companies. However, in 1997, 1998 and 1999, sales to the
Company's top ten customers accounted for approximately 84%, 84% and 78%,
respectively, of total net sales. One of the Company's customers, Bayer
Corporation ("Bayer"), accounted for approximately 47%, 40% and 41% of the
Company's net sales in 1997, 1998 and 1999, respectively, while another
customer, Centeon Pharma GmbH, accounted for 11% and 14% of net sales in 1997
and 1998, respectively. During 1997 and 1999, sales to Alpha Therapeutic
Corporation accounted for approximately 12% and 10% of nets sales, respectively.
During 1997, 1998 and 1999, no other single customer of the Company accounted
for greater than 10% of net sales. In 1997, 1998 and 1999, the Company's
domestic sales represented approximately 74%, 63% and 77%, respectively, of net
sales.

  Therapeutic Products

     The majority of the Company's therapeutic products are sold through its own
sales force and, in limited markets, through independent brokers, to major
biological product manufacturers. The majority of the
                                        9
<PAGE>   12

Company's specialty antibodies for therapeutic use are sold pursuant to annual
purchase orders, with prices generally negotiated annually. The Company's
non-specialty antibodies are generally sold through long-term supply contracts
pursuant to which the total production of specific donor centers is generally
dedicated to specific customers. The Company is a party to four five-year supply
contracts with Bayer for the sale of non-specialty antibodies produced at a
number of its non-specialty donor centers. Such contracts, three of which
expired in 1999 and have been extended on an interim basis and one which will
expire in 2002, accounted for approximately 27% of the Company's net sales in
1999.

     The Company also is a party to several supply contracts with Alpha
Therapeutic Corporation for the sale of non-specialty antibodies collected at
certain of the donor centers acquired. The contracts vary in term, price and
volume levels, but are generally similar to the Company's other supply contracts
for non-specialty antibodies.

     Early termination or the inability of the Company to renew its supply
agreements could adversely effect the Company.

  Diagnostic Products

     The Company's monoclonal and polyclonal antibodies are sold to more than
100 manufacturers or suppliers of blood typing reagents and independent brokers.
While a significant amount of the Company's monoclonal antibody sales are made
pursuant to supply agreements, the majority are regarded as spot sales. The
polyclonal blood typing reagent market can be characterized as a spot market
with limited advance sales and commitments to purchase typically made orally
after the customer receives a sample. Due to the technical nature of the
product, monoclonal antibodies used to manufacture blood typing reagents require
a highly trained and technical sales staff. The Company's sales and technical
support staff for this product is located in Scotland. The capabilities of the
Company's facilities and staff allow for the marketing of monoclonal antibodies
for blood typing in many forms, from unfinished product to finished, vialed and
branded product.

     The Company sells its Pentex(R) line of blood proteins products worldwide
to over 200 customers in 25 countries. These customers are generally major
biotechnology or biopharmaceutical companies that manufacture recombinant,
therapeutic biopharmaceutical products, media formulators or major diagnostics
companies that manufacture blood typing and other diagnostic reagents. A small
portion of the Company's sales of blood proteins are to the research market. The
Company's marketing strategy involves identifying candidate customers,
maintaining intimate knowledge of next generation projects of these companies
and creating working relationships with the research teams of such companies.
The Company believes that by competing at the earliest development stages, it
increases its potential for being a sole source provider. While sales of the
EX-CYTE(R) product line have historically been made through annual purchase
orders, the Company is experiencing an increased desire of its customers to
enter into long-term supply agreements to ensure their access to the product.
For example, subsequent to year-end, the Company entered into a long-term supply
contract with a major pharmaceutical company that under certain circumstances
obligates the Company and the customer to supply and buy, respectively, certain
amounts of EX-CYTE(R) products over the term of the contract.

     In 1999, the Company's clinical diagnostic antibodies were sold to more
than 100 customers in 16 countries. Clinical diagnostic antibodies are primarily
sold to manufacturers of diagnostic test kits for incorporation as controls or
for use in product development projects. The Company maintains a separate sales
group dedicated to this product line due to the large number of customers
requiring personalized treatment and the special product knowledge required. The
Company sells a significant portion of its clinical diagnostic antibodies
pursuant to a supply contract with a customer that expires in December 2000.

ACQUISITIONS

     The commercial sector of the blood products and services industry has
undergone a consolidation driven largely by the rising cost and complexity
related to increased regulatory compliance requirements. A significant component
of the Company's recent business strategy had included acquisitions that enabled
the Company to participate in the consolidation of the industry and to add
complementary products and services
                                       10
<PAGE>   13

that expanded the Company's current product and service portfolio. This strategy
resulted in the acquisition of virtually all of the Company's 47 non-specialty
donor centers since December 1994. However, owing to the increased costs of
regulation, combined with lower production and resulting higher per unit costs
and the inability of this Company to pass these costs on to its customers, the
Company is contemplating a restructuring or reorganization of its non-specialty
donor centers, the results of which could include a divestiture of all or a
portion of the 47 centers.

     The Company intends to pursue acquisitions of businesses that provide
services and products that are complementary to its existing diagnostic and
bioscience businesses, such as the 1999 acquisition of Pentex. However, there
can be no assurance that the Company will be able to complete suitable
acquisitions in the future or successfully integrate any such acquisitions into
its existing operations.

QUALITY ASSURANCE

     The Company maintains quality assurance programs designed to assure the
efficacy and safety of its products and compliance with the requirements of
regulatory authorities, industry trade associations and its customers. Through
the Company's Quality Assurance Program, an internally maintained regulatory
compliance program, the Company conducts periodic audits of each facility to
monitor staff adherence to regulations and protocols. These audits are designed
to ensure adherence to Company procedures and effectiveness of staff training
efforts. The Company subscribes to the Quality Plasma Program ("QPP"), which is
a donor center certification program administered by the American Blood
Resources Association ("ABRA"), an industry trade organization. ABRA certifies
only those facilities that meet its standards and provide the highest quality
products. Most of the Company's customers require their suppliers to be QPP
certified. All of the Company's donor center facilities are currently QPP
certified.

COMPETITION

  Therapeutic Products

     The Therapeutic Products segment is engaged in the business of providing
antibodies, which is a competitive and continually changing field. The Company
competes for customers with other antibody suppliers on the basis of price,
reliability and quality of product, breadth of product line and the ability to
provide value-added services. While the Company believes that its proprietary
anti-D vaccination protocol and extensive donor base of individuals with high
concentrations of pre-existing anti-D antibodies provides it a competitive
advantage and allows it to offer a premium product in terms of quality, the
Company has recently experienced, and expects to continue to experience,
increased competition for anti-D antibodies from other independent collection
companies. The Company believes that future increases in the production of
anti-D antibodies by other suppliers could have a further adverse effect on the
Company through decreased orders for its product or lower selling prices per
unit.

     In certain markets, the Company competes for donors by means of financial
incentives which the Company offers for the donation of the antibodies it
collects, by providing donor services, by implementing programs designed to
attract and retain donors through education as to the uses for collected
antibodies, by encouraging groups to have their members become antibody donors
and by improving the attractiveness of the Company's donor centers. Certain of
the Company's specialty antibodies are derived from donors with rare antibody
characteristics, resulting in increased competition for such donors. If the
Company is unable to maintain and expand its donor base, its business and future
prospects may be adversely affected.

     Furthermore, several companies are attempting to develop and market
products to treat diseases based upon technology that may lessen or eliminate
the need for certain antibodies or other plasma-based products. Such products,
if successfully developed and marketed, could adversely affect the demand for
antibodies and other plasma-based products.

     The Company believes it takes on average 8-10 months to obtain FDA approval
for a new non-specialty donor center, and takes up to 12 months to obtain the
necessary regulatory approvals in order to begin shipping product from a
specialty donor center which immunizes its donors. In addition to these
regulatory

                                       11
<PAGE>   14

requirements, once the center is operational, a stable donor base must be
established and maintained as repeat donors are critical to success for both
quality control and profitability. A significant volume of donated antibodies
and sophisticated screening and immunization procedures also are necessary in
order to provide the diversity and quality of antibody products demanded by the
market.

  Diagnostic Products

     The primary competition for monoclonal antibodies used in blood typing
reagents (both OEM and bulk material) comes from customers that are vertically
integrated, and thus provide antibodies for their own use, and smaller,
independent manufacturers that offer a more limited range of product. The
Company believes that its large range of proprietary antibodies and state of the
art facilities provides it a competitive advantage with respect to these
competitors.

     The Company faces its most direct competition for its BSA and similar
Pentex(R) branded products from a single, long established supplier in the
market who has a full line similar to the Company. However, this competitor has
experienced a recent supply interruption due to regulatory compliance issues,
which has contributed to demand for the Company's BSA that exceeds its current
production capacity. To increase its production, the Company is undergoing a $2
million expansion to increase its BSA manufacturing capacity by approximately
30%. The Company currently does not face significant competition for its
EX-CYTE(R) product line.

     The Company faces competition for its clinical diagnostic antibodies
primarily from other independent suppliers of antibodies that operate donor
centers.

     There can be no assurance that competition for customers, donors, end
products or otherwise will not adversely affect the Company.

GOVERNMENT AND INDUSTRY REGULATION

     General.  The Company's activities are subject to significant regulation by
numerous governmental authorities in the United States and internationally.
These regulatory authorities govern the collection, testing, manufacturing,
safety, efficacy, labeling, storage, record keeping, transportation, approval,
advertising and promotion of the Company's products, as well as the training of
its employees. The Company believes it is in substantial compliance with all
relevant laws and regulations.

     The Company is subject to extensive FDA regulation, primarily through the
requirements of the Public Health Service Act and the Food, Drug and Cosmetic
Act. Excluding one recently opened location, all of the Company's donor centers
and the Company's monoclonal manufacturing facilities hold FDA biologics
licenses ("BLA") and the Company's specialty donor centers have numerous
supplements to the source plasma license, permitting the production and sale of
specialty antibodies and the immunization of donors. While the Company is also
licensed to immunize donors at certain of its primarily non-specialty donor
centers, it is not currently collecting specialty antibodies at those 47
centers.

     During 1998, the FDA issued proposals to create a single license for
biologic products, replacing the former establishment licenses and product
licenses, with the goal of reducing unnecessary burdens for the industry without
diminishing public health protection. Under these regulations, the FDA issues a
single license to manufacturers of multiple biological products, such as
specialty antibodies and product derived from immunized donors. Currently, the
Company's 17 specialty donor centers operate under a single license, as do 46 of
its 47 non-specialty donor centers. The Company is currently seeking approval
for a recently opened non-specialty donor center. The Company believes that as a
result of these new regulations, other collectors might attempt to enter the
specialty antibody market, as they will generally be allowed to immunize donors
at historically non-specialty donor centers during the application process.
However, the Company believes that its extensive experience in immunization will
be a competitive advantage, as it expects the difficulty of the application and
approval process to increase, particularly for centers operated independently.

     New facilities, products and operating procedures at each location must
undergo approval processes through the FDA. Significant changes to existing
facilities, products or operating procedures must also
                                       12
<PAGE>   15

undergo FDA review prior to implementation. The Company's FDA-licensed donor
centers and central testing laboratory in the United States and its monoclonal
manufacturing facilities in the U.K. are required to adhere to FDA current Good
Manufacturing Practices (cGMP) and are routinely inspected by the FDA.
Furthermore, the Company's protein fractionation site is an FDA-registered
facility. Donor centers must meet detailed standards for, among other things,
the screening of donors, obtaining informed consents from donors, the collection
of antibodies, training of personnel and the testing, handling and disposal of
biologic products. If the FDA believes that a facility is not in compliance with
applicable laws and regulations, generally as a result of an on-site inspection,
it typically issues a deficiency notice known as a Form 483 and, subsequently, a
warning letter if such deficiencies are not adequately responded to or addressed
in an appropriate and timely manner. An inadequate response to a warning letter
could ultimately result in the detainment or seizure of products, issuance of a
recall, enjoinment of future operations and the assessment of civil and criminal
penalties against the Company, its officers or its employees. In addition,
approvals or licenses could be temporarily suspended or revoked in certain
circumstances. Failure to comply with regulatory requirements or a significant
adverse regulatory action could have a material adverse effect on the Company.

     Due in part to the implementation of an approach by the FDA known as "Team
Biologics", there has been an increasing level of regulatory scrutiny in the
biologics industry resulting in more detailed and frequent inspections, and what
the Company believes are a greater number of observations cited per inspection,
deficiency notices and warning letters. On occasion, the Company has received
notifications and warning letters from the FDA of possible deficiencies in the
Company's compliance with FDA requirements. To date, the Company believes that
it has adequately addressed or corrected such deficiencies and that it is in
material compliance with all relevant laws and regulations. However, since all
of the Company's operations have not yet been fully subjected to Team Biologics
inspections, it is unable to determine what impact, if any, such inspections
will have on the Company and its operations when they occur. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Overview".

     The Company is also subject to additional inspections by customer quality
assurance auditors, ABRA auditors, the Health Care Financing Administration
("HCFA") and state health departments. HCFA regulates and certifies all clinical
testing performed at each donor center and the Company's central testing
laboratory under the Clinical Laboratories Improvement Act of 1988. The
Company's central testing laboratory in Atlanta, Georgia is licensed by the FDA
and the State of Georgia.

     Outside the United States, sales of the Company's products are subject to
additional regulatory requirements, which vary widely from country to country.
In particular, much of Company's domestic plasma operations, including its
central testing laboratory, are subject to inspection and approval by various
German regulatory bodies, as a significant portion of its therapeutic antibody
products, including those sold to domestic affiliates of German companies, are
ultimately further manufactured or sold in Germany. These regulations, while
similar in scope to those promulgated by the FDA, are often more restrictive.

     In the United Kingdom, the Company is subject to the U.K. Health and Safety
at Work Act, which regulates the safety precautions required of manufacturers in
the United Kingdom, and to various other regulations covering the use of
genetically engineered organisms in laboratory and manufacturing processes. In
certain countries, the Company's customers are subject to regulatory
requirements that require additional inspection and approval of the Company's
facilities prior to the shipment of products to such countries. Changes in
existing federal, state or foreign laws or regulations, or the Company's
inability to comply with such regulations, could have an adverse effect on the
Company's business.

     The Company is also subject to numerous industry and customer-mandated
standards. Industry groups such as ABRA and the Company's customers continually
evaluate their practices and procedures regarding new information or public
concerns over diseases which may be transmitted from donors through their blood
or blood components. Based upon such evaluation, a certain portion of the
population may be prohibited from donating in the future, or certain new testing
and screening procedures may be required to be performed with respect to certain
donors. The Company is also subject to routine inspections of its facilities by
its customers, whose approval must generally be obtained for each donor center
prior to shipping product.

                                       13
<PAGE>   16

     One specific concern currently facing the industry is Creutzfeld-Jakob
disease ("CJD") and new variant CJD ("nvCJD"), an often fatal disease occurring
sporadically in the world at an incidence of about one per million population
per year and which has been reportedly linked in some cases to bovine spongiform
encephalopathy, also known as "mad cow disease". However, no evidence currently
exists that CJD can be transmitted by blood or plasma products and the risk, if
any, is believed to be small and at present only theoretical. While no
acceptable testing or screening procedure currently exists to detect CJD, it has
generally been found to have a higher incidence in the older population. In
response to this concern and at the request of several of its customers, the
Company has ceased collecting certain antibodies from donors over the age of 59
at certain of its donor centers. As a further precaution against the theoretical
transmission of nvCJD, the FDA recently issued guidance banning plasma and blood
donations from individuals that had spent extended periods of time in the United
Kingdom during the mad cow epidemic there from 1980 to 1996.

     Another standard voluntarily adopted by the industry relates to the
acceptance of new donors. In an effort to further minimize the potential that
infected plasma could enter the manufacturing process undetected, all first time
donors' plasma is excluded from shipment and further manufacture unless a
second, negative set of test results is also obtained on a second donation
within six months, essentially precluding one-time donations. Also, in order to
further shorten the "window period" during which time a donor is potentially
infectious but is not detected as such by current screening tests that measure
antibody response to the viruses, certain of the Company's therapeutic customers
have implemented a testing method, Nucleic Acid Amplification ("NAT"), sometimes
known as Polymerase Chain Reaction ("PCR") technology. PCR/NAT testing is a
method used to detect the presence of genetic material of problem viruses before
antibodies against those viruses can be formed. While the test is not yet
required or approved by the FDA, the Company's customers have begun testing all
source plasma for hepatitis C and, in most cases, hepatitis B and HIV, as a
further measure of safety.

     Although the Company does not believe that the potential loss of donors
resulting from these new standards will have a material impact on its operating
results, there is no assurance that the long-term impact of these standards, or
the imposition of other blood safety measures, will not have a material adverse
effect on future operations.

     Certain of the products produced at the Company's protein fractionation
facility in Kankakee, Illinois are considered "medical devices" under the Food,
Drug and Cosmetic Act and, accordingly, are subject to its general control
provisions that include requirements for registration, listing of devices, cGMP,
labeling and prohibitions against misbranding and adulteration. These products,
which represent an insignificant amount of the Company's sales, nonetheless
subject the Company to FDA inspection and scrutiny. Furthermore, the FDA has
indicated in certain guidance documents and in public meetings that it intends
to more closely regulate tissue culture media, such as the Company's
EX-CYTE()(R) products, that are used in the manufacture of injectable products.
While there has been no indication as to how these products will be classified
and therefore with which standards they will need to comply, the FDA has
indicated that, at a minimum, manufactures of tissue culture media should adhere
to cGMP standards. The Company currently produces EX-CYTE()(R) in a recently
expanded facility that was constructed to pharmaceutical cGMP standards. The
imposition of additional regulatory requirements for its protein fractionation
facility could adversely affect the Company.

     Federal, state and foreign laws and regulations regarding the manufacture
and sale of the Company's products are subject to future change. The Company
cannot predict what impact, if any, such change might have on its business.
However, such changes could have a material impact on the Company's business.

     Other.  The Company is also subject to government regulations enforced
under the Environmental Protection Act, the Clean Air Act, the Clean Water Act,
the National Environmental Policy Act, the Toxic Substances Control Act, the
Resource Conservation and Recovery Act, the Medical Waste Tracking Act, and
other national, state or local restrictions. The Company is also subject to
workplace safety regulations under the Occupational Safety and Health Act
(OSHA). The Company believes that it is in substantial compliance with all
applicable regulations.

INFORMATION TECHNOLOGY

     The Company is currently pursuing several information technology ("IT")
initiatives that it believes will streamline many of the tasks currently being
performed throughout its operations. The Company also believes that certain
automation initiatives could help mitigate a significant amount of risk
currently borne by the Company by operating in a highly regulated environment.
Most significant of these initiatives involves the automation of the Company's
specialty donor center network. During 1998, the Company contracted with a third
party vendor for the custom development of a software system. In the third
quarter of 1999, when it was apparent to the Company that the project would not
be completed in a time period and at a cost acceptable to the Company, it
terminated the contract with the vendor and wrote off the $4.2 million of
previously capitalized costs. In September of 1999, the Company entered into a
licensing arrangement with another vendor for the use of its existing donor
center management system, which it believes will be implemented sooner and for
less overall costs than the previous project. The Company is currently in the
process of configuring and validating the system to its specific needs and
expects implementation of the system to begin at its 17 specialty donor centers
in the fourth quarter of 2000.

     The Company is pursuing a number of other automation projects, including
sales order processing, purchasing and invoicing and has recently upgraded its
financial and accounting system. The Company anticipates that further IT
expenditures may be necessary, such as a manufacturing resource planning system
for its monoclonal antibody manufacturing and protein fractionation facilities.

     There can be no assurance that the Company will be successful in its IT
efforts, or that the Company will achieve any of the anticipated benefits of its
various IT initiatives.

THIRD PARTY REIMBURSEMENT

     In both domestic and foreign markets, sales by the Company's customers may
depend in part on the availability of reimbursement from third-party payors such
as government health administration authorities, private health insurers and
other similar organizations. Third-party payors are continually challenging the
price and cost-effectiveness of medical products and services. There can be no
assurance that pricing pressures which may be experienced by the Company's
customers will not adversely affect the Company because of a determination that
these products are not cost effective or because of inadequate third-party
reimbursement levels to such customers.

EMPLOYEES

     As of March 24, 2000, the Company employed approximately 1,205 persons,
1,120 of whom were located in the United States and 85 of whom were located in
the United Kingdom. Of the Company's U.S.-based employees, 33 that were hired in
connection with the acquisition of Pentex are members of a collective bargaining
unit. The Company believes that its relationship with its employees is generally
satisfactory.

PRODUCT LIABILITY AND INSURANCE

     The sourcing, processing and sale of the Company's products involve a risk
of product and professional liability claims. The Company has obtained product
liability insurance in an amount of $3.0 million per incident and $3.0 million
in the aggregate per annum for each of the Company's facilities on an occurrence
basis and professional liability insurance in the same amounts on a claims made
basis. The Company also has a $10.0 million excess liability umbrella insurance
policy. There can be no assurance that the coverage limits of the Company's
insurance policies and/or any rights of indemnification and contribution that
the Company may have will offset potential claims. A successful claim against
the Company in excess of insurance coverage and not subject to indemnification
could have a material adverse effect on the Company.

ITEM 2.  PROPERTIES

     The Company's 64 donor centers are located in 21 states and the District of
Columbia, principally in the South, Southwest, Midwest and Northwest United
States. The donor centers range in size from approximately 1,000 to 10,000
square feet and are generally leased with five-year terms. A majority of these
leases contain renewal options that permit the Company to renew the leases for a
five-year period at the then fair rental value. The Company believes that in the
normal course of its business, it will be able to renew its existing leases or
relocate its operations subject to regulatory approval. See Item 1,
"Business -- Operations."

     The Company's central testing laboratory and international headquarters are
located in Atlanta, Georgia; its monoclonal research and development
laboratories and the Company's FDA licensed monoclonal antibody manufacturing
facilities are located in Edinburgh, Scotland (large scale monoclonal
production) and Livingston, Scotland (vialing and labeling). All of these
facilities are leased with terms expiring through 2021.

     The Company's owned blood protein fractionation facility, acquired in the
Pentex transaction, is a 61,000 square foot facility located on five acres in
Kankakee, Illinois. The facility includes a 17,000 expansion completed during
1999 that is dedicated to the manufacturing of EX-CYTE(R).

ITEM 3.  LEGAL PROCEEDINGS

     The Company is a party to litigation in the ordinary course of business.
The Company does not believe that such litigation is likely to have a material
adverse effect on its financial position or results of operations.

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

     No matter was submitted to a vote of security holders in the fourth quarter
of the fiscal year ended December 26, 1999.

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

OVERVIEW

  General

     The Company is a leading worldwide provider of biological materials and
services to major healthcare companies. The Company provides value-added
antibody-based products that are used as the active ingredients in therapeutic
products for the treatment and management of diseases such as Rh incompatibility
in newborns, rabies and hepatitis and in diagnostic products such as blood
typing reagents and diagnostic test kits. Through its protein fractionation
facility, the Company provides a variety of proteins used in diagnostic reagents
and tissue culture media components for use as additives in biotech products.
The Company is also engaged in the development, manufacturing and sale of
monoclonal antibodies at its facilities in the United Kingdom. As of March 24,
2000, the Company operated 64 donor centers, 17 of which specialize in the
collection of specialty antibodies and 47 of which primarily collect source
plasma containing non-specialty antibodies from which a number of products,
primarily IVIG, are produced.

     Owing in part to increasing margin pressures and the inability of the
Company to pass increased costs on to its customers, the Company is currently
performing a strategic review of its non-specialty antibody operations, and is
in discussions which could result in a divestiture of all or a portion of its 47
non-specialty donor centers.

     On December 29, 1998, the Company acquired Pentex for $29 million. Pentex,
renamed Serologicals Proteins, provides a full range of over 100 distinct animal
protein products derived from different animal species. A number of these
products, such as bovine serum albumin (BSA), are primarily supplied to
healthcare companies for use in diagnostic reagents. The Company also provides a
line of highly purified animal proteins known as tissue culture media components
that are used primarily by biopharmaceutical companies as nutrient additives in
cell culture media. One example of these media components is Bovine
EXCYTE(R), Growth Enhancement Media Supplement, which is produced through a
patented manufacturing process. The Company accounted for the acquisition as a
purchase in accordance with Accounting Principles Board Opinion No. 16.

     For management purposes, the operations of the Company's subsidiaries are
organized into two primary operating segments, Therapeutic Products and
Diagnostic Products. These segments are based primarily on the differing nature
of the ultimate end use of the Company's products, the differing production and
other value-added processes performed by the Company with respect to the
products and, to a lesser extent, the differing customer bases to which each
reportable segment sells its products.

     The activities of the Therapeutic Products segment primarily include the
collection and sale of specialty and non-specialty human antibodies that are
used as the active ingredients in therapeutic products for the treatment and
management of various diseases. The activities of the Diagnostic Products
segment include the Company's monoclonal antibody production facilities and
certain human-sourced, polyclonal antibodies. While an increasing number of
Pentex(R)-branded products are being used in therapeutic end products, the
management of this business is performed within the Company's diagnostic
business unit and, accordingly, is included in the Diagnostic Products
reportable business segment. The antibodies and other proteins provided by the
Diagnostic Products segment are used in diagnostic products such as blood typing
reagents and diagnostic test kits and as nutrient additives in biotech products.

  1999 Review

     During April 1999, the Company was notified by two of its international
customers that their fractionation facilities used in the manufacture of anti-D
immune globulin would be closed for extended periods of time for various quality
control enhancements, due in part to changing regulatory requirements, and in
one case, the validation of manufacturing procedures relating to the customer's
product. These cancellations, coupled with a general softness in the anti-D
market, led to 1999 anti-D sales that were approximately 40% lower than the
previous year. The Company expects a modest recovery in anti-D sales in 2000.

     During the third quarter of 1999, the Company discovered during an internal
quality assurance audit that a limited number of product tests performed at its
central testing laboratory in Atlanta, Georgia had not been performed in strict
accordance with the Company's standard operating procedures regarding sample
storage requirements. Pending a full investigation of the matter, the Company
ceased shipping all products that had been tested at its laboratory, including
those tested after the deviation from standard operating procedures had been
identified and corrected. While the affected units that were ultimately deemed
unusable and thus written off amounted to less than $400,000, shipment of the
unaffected units were put on hold pending final Company and customer approval.
As of December 26, 1999, the Company had shipped the majority of the product
delayed as a direct result of this issue.

     During 1999, the Company recorded special charges totaling approximately
$34.0 million. These charges consisted of (i) a $24.9 million non-cash asset
impairment charge relating to a partial write-off of the goodwill of the
Company's non-specialty antibody business; (ii) $2.0 million in product claims;
(iii) a $1.2 million non-cash expense for the write down to estimated fair
market value and $117,000 on the subsequent loss on disposition of the Company's
clinical trial site; (iv) a $4.2 million non-cash write-off of previously
capitalized software development costs resulting from the cancellation of a
custom development project in favor of an alternative vendor; and (v) $1.6
million of separation and other employee benefits payable to the Company's
former chief executive officer, its chairman of the board and approximately 12
other corporate-based employees.

     In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" ("SAB
No. 101"). This statement summarizes certain staff views in applying generally
accepted accounting principles to revenue recognition in financial statements.
SAB No. 101 provides additional guidance regarding when revenue is realized,
earned and properly recognized. As part of its assessment of its compliance with
SAB 101, the Company determined that its revenue recognition policy as it
related to the timing of recording sales under an existing arrangement with a
single customer of its Serologicals Proteins subsidiary should be amended. The
Company also had significant changes in its operations during 1999, which it
believes caused certain errors to occur in recording certain sales, cost of
sales and other expenses in the first three fiscal quarters of 1999 that were
previously undetected. As a result, the Company has restated its unaudited
results of operations for the first three fiscal quarters of 1999. These items
related only to the Company's 1999 unaudited quarterly operating results and had
no impact on previously reported cash flows. See Note 15 to Notes to
Consolidated Financial Statements where the restated unaudited quarterly results
of operations are presented.

  Industry Trends

     Increasing regulatory scrutiny continues to be a significant factor shaping
the biologics industry, resulting in more detailed and frequent Food and Drug
Administration (FDA) inspections of the Company's and its customers' operations,
a potentially greater number of observations, deficiency notices and warning
letters per inspection, and more product recalls and temporary or permanent
closures of facilities. One factor contributing to this trend is the FDA's
implementation of an approach to inspections of donor centers and laboratory
testing and manufacturing facilities, including the Company's customers',
entitled "Team Biologics". Under this approach, substantially all such
inspections are performed by highly trained field investigators who focus
extensively on the FDA's current good manufacturing practices (cGMP) and quality
systems. This approach was first applied to plasma fractionators and
subsequently to other biologic product areas, including certain of the Company's
operations. Several large fractionators, including certain of the Company's
customers, have been affected in varying degrees, from complete shutdowns of
manufacturing facilities to operating under a consent decree to bring their
facilities into compliance. Furthermore, the Company believes certain
manufacturers have experienced a longer than anticipated FDA approval process of
new, relocated or expanded manufacturing and laboratory testing facilities.

     On occasion, the Company has received notifications and warning letters
from the FDA related to possible deficiencies in the Company's compliance with
cGMP and other FDA requirements. To date, the Company believes that it has
adequately addressed or corrected such deficiencies and that it is in
substantial compliance with all relevant laws and regulations. However, since
all of the Company's operations have not yet
                                       21
<PAGE>   24

been fully subjected to Team Biologics inspections, it is unable to determine
what impact, if any, such inspections will have on the Company and its
operations when they occur.

     Another trend the industry is currently experiencing is the continuing
imposition of more rigorous donor screening and other standards by the FDA and
certain regulatory bodies in foreign countries, in particular those governing
the manufacture and sale of plasma-based products in Germany, which represents a
significant portion of the Company's sales. Furthermore, the Company's customers
and certain industry trade organizations continue to impose stricter standards.
Such standards, including donor age restrictions, the elimination of one-time
and certain other infrequent donors, restrictions on donors who have traveled to
certain foreign countries and the introduction of new testing techniques have
reduced the pool of, and increased the competition for, potential donors.
Furthermore, the Company believes that, owing in part to the general strength of
the national economy, the financial incentives provided particularly to donors
of non-specialty antibodies are potentially becoming relatively less attractive,
further decreasing the pool of potential donors.

     While the Company continues to be adversely impacted by reduced collections
of non-specialty antibodies, increased collection costs of certain of its
products, delayed or reduced shipments of certain products and the other factors
identified above, it believes that the current supply and demand factors
affecting the industry could enhance the pricing of non-specialty antibodies in
the long term. However, the Company does not anticipate profitability of this
product to return to its historical levels. Due in part to the strength of the
end-use demand, the Company does remain optimistic about the longer-term
potential for specialty antibodies, including anti-hepatitis, anti-rabies and
anti-D.

     In contrast to these constraints impacting the supply of antibodies, in
particular non-specialty antibodies, current demand for certain of the
antibodies the Company offers has increased for a variety of reasons, including
increased demand for the end products into which they are manufactured, expanded
use of the various end products and increased manufacturing capacity of certain
fractionators as they are able to bring their facilities into compliance. These
factors have led to recent, and in some cases critical, shortages of certain
plasma-based products, most notably IVIG.

     In order to meet this increased demand for, and to improve the
profitability of, its non-specialty antibody business, the Company has pursued
various alternatives to increase production at its non-specialty donor centers.
However, the Company believes that the non-specialty antibody business may no
longer match its strategic objectives of providing high margin, value-added
products to the pharmaceutical, biotechnology and diagnostic industries. As a
result, the Company has been performing a strategic review of its non-specialty
operations, and is in discussions which could result in a divestiture of all or
a portion of its 47 non-specialty donor centers. However, there can be no
assurance that the Company's efforts will be successful, or that any further
impact related to any of the factors discussed above will not have a material
adverse effect on the Company or its operations.

RESULTS OF OPERATIONS

     The following discussion and analysis of the Company's financial condition
and results of operations should be read in conjunction with the Consolidated
Financial Statements and Notes thereto. The following table sets forth certain
consolidated operating data of the Company as a percentage of net sales for the
fiscal years indicated below.

YEARS ENDED DECEMBER 26, 1999 AND DECEMBER 27, 1998

NET SALES

CONSOLIDATED

     Consolidated net sales increased 5.4%, or approximately $6.7 million, from
$123.1 million in 1998 to $129.7 million in 1999. Of the increase, approximately
$20.3 million was attributable to the acquisition of Pentex, which was offset by
a net decrease in sales from its other operations.

THERAPEUTIC PRODUCTS

     Net sales of Therapeutic Products decreased approximately $11.0 million, or
10.8%, from $102.1 million in 1997 to $91.1 million in 1999. The decrease was
primarily the result of a decrease in sales of anti-D antibodies of
approximately $15.2 million, due in large part to the cancellation of sales from
two customers, offset by an increase in sales of non-specialty antibodies. The
increase in sales of non-specialty antibodies was due in large part to an
increase in the percentage of the product sold on a "gross" pricing basis, for
which the increased selling price is reflective of the Company's provision of
laboratory testing services and certain donor supplies that were previously
borne by the customer on a net basis. Total net sales of specialty antibodies
decreased approximately $14.9 million, or 32.6%, from $45.7 million in 1998 to
$30.8 million in the current year, while sales of non-specialty antibodies
increased $3.8 million, or 6.7%, from $56.4 million in 1998 to $60.2 million in
the current year.

DIAGNOSTIC PRODUCTS

     Net sales of Diagnostic Products increased approximately $17.7 million, or
88.0%, from $20.1 million in 1998 to $37.8 million in the current year.
Substantially all of the increase was attributable to the acquisition of Pentex.
Total net sales of monoclonal antibodies decreased $941,000, or 7.7%, from $12.3
million in 1998 to $11.3 million in 1999. The remaining net sales, primarily
human-sourced antibodies used in blood typing reagents and diagnostic test kits,
decreased approximately $1.6 million, or 21.0%, from $7.8 million in the prior
year to $6.2 million in 1999.

GROSS PROFIT

CONSOLIDATED

     Consolidated gross profit decreased 14.9%, or approximately $6.2 million,
from $41.8 million in 1998 to $35.6 million in the current year. This decrease
resulted primarily from decreased gross profit resulting from decreased sales
from existing operations, offset by approximately $10.6 million resulting from
the acquisition of Pentex. Gross profit as a percentage of net sales ("gross
margin") decreased from 34.0% in 1998 to 27.4% in the current year, largely as a
result of lower production at many of the Company's primarily non-specialty
donor centers and production decreases of anti-D antibodies due to reduced
orders, resulting in decreased fixed cost absorption and a lower gross profit
per unit. Furthermore, the Company has experienced increased costs of regulatory
compliance.

THERAPEUTIC PRODUCTS

     Gross profit from Therapeutic Products decreased approximately $13.6
million, or 45.9%, from $29.6 million in 1998 to $16.0 million in the current
year. This decrease was primarily due to lower sales of relatively higher margin
anti-D antibodies and lower gross profit per unit due to planned production
decreases in light of reduced orders. Additionally, gross profit on
non-specialty antibodies decreased, primarily as a result of the level of
non-specialty antibody production. Gross margin decreased from 29.0% in 1998 to
17.6% in 1999, primarily as a result of the increase in sales of non-specialty
antibodies as a percent of total Therapeutic Products sales, from 55% in 1998 to
66% in the current year. Finally, gross margin was also impacted by the increase
in the percentage of non-specialty antibodies sold on a gross basis, as there
was relatively insignificant gross profit attributed to the additional revenue.

                                       23
<PAGE>   26

DIAGNOSTIC PRODUCTS

     Gross profit from Diagnostic Products increased approximately $7.9 million,
or 64.0%, from $12.3 million in 1998 to $20.1 million in 1999. The majority of
this increase was attributable to the acquisition of Pentex at the beginning of
the current fiscal year, offset by lower gross profit from existing operations.
The decrease in gross profit from existing operations was primarily a result of
lower sales of monoclonal antibodies, and to a lesser degree, lower gross profit
per unit of sales of certain diagnostic products. Gross margin for the
Diagnostic Products segment decreased from 61.1% to 53.3%, primarily due to
lower sales of relatively higher margin monoclonal antibodies.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

     Consolidated selling, general and administrative expenses increased 20.7%,
or $3.1 million, from $14.9 million in 1998 to $18.0 million in the current
year. Of the increase, approximately $2.3 million was attributable to ongoing
selling, general and administrative expenses incurred as a result of the Pentex
acquisition, while the remainder was due to increases in general corporate
overhead, offset by decreased product development expenses.

OTHER EXPENSE, NET

     Consolidated other expense, net, which primarily consists of amortization
of goodwill and other intangible assets and gains and losses from foreign
currency translations, increased approximately $1.8 million, or 67.4%, from $2.7
million in 1998 to $4.5 million in the current year. Of the increase,
approximately $784,000 was the result of additional amortization expense
associated with a decrease in the useful lives used in amortizing intangible
assets of the Company's non-specialty antibody business and approximately
$772,000 was attributable to amortization expense related to the Pentex
acquisition completed at the beginning of the year.

INTEREST EXPENSE (INCOME), NET

     Consolidated interest expense (income), net increased approximately $1.4
million, from net interest income of $846,000 in 1998 to net interest expense of
$543,000 in 1999. The increase was primarily attributable to the borrowings
under the Company's Revolver (as hereafter defined), used primarily in the
repurchase of approximately $17.0 million of the Company's common stock and to
fund working capital during the third and fourth quarters of 1999 when the
Company experienced shipping delays for a significant number of its products.

PROVISION (BENEFIT) FOR INCOME TAXES

     The provision (benefit) for income taxes as a percentage of income (loss)
before income taxes decreased from 34.7% in 1998 to 28.0% in 1999. This change
was primarily due to the non-deductible portion of goodwill written off during
1999.

YEARS ENDED DECEMBER 27, 1998 AND DECEMBER 28, 1997

NET SALES

CONSOLIDATED

     Consolidated net sales increased 26.2%, or approximately $25.5 million,
from $97.5 million in 1997 to $123.1 million in 1998. Of this increase,
approximately $17.0 million was attributable to increased sales from existing
operations, while the remainder, or approximately $8.5 million, was attributable
to the full-period effect of acquisitions completed during 1997 and 1998.

THERAPEUTIC PRODUCTS

     Net sales of Therapeutic Products increased approximately $22.9 million, or
28.9%, from $79.2 million in 1997 to $102.1 million in 1998. Of this increase,
approximately $16.5 million was from increased sales of antibodies from existing
operations, most significantly anti-D, and to a lesser extent, non-specialty
antibodies.
                                       24
<PAGE>   27

The increase in sales of anti-D antibodies was a result of both pricing and
volume increases, while the increase in sales of non-specialty antibodies was
due in large part to an increase in the percentage of the product sold on a
"gross" pricing basis. The remainder of the increase, or approximately $6.3
million, was the result of acquisitions completed during 1997 and 1998. The
majority of the sales attributable to the acquisitions was of non-specialty
antibodies. Total net sales of specialty antibodies increased approximately
$11.0 million, or 31.8%, from $34.7 million in 1997 to $45.7 million in 1998,
while total net sales of non-specialty antibodies increased approximately $11.9
million, or 26.6%, from $44.6 million in 1997 to $56.4 million in 1998.

DIAGNOSTIC PRODUCTS

     Net sales of Diagnostic Products increased approximately $1.8 million, or
10.0%, from $18.3 million in 1997 to $20.1 million in 1998. Of the increase,
$492,000 was primarily the result of increased sales of antibodies used in blood
typing reagents, which were offset by marginal decreases in certain other
diagnostic products. The remainder of the increase, or $1.4 million, was
attributable to an acquisition completed during 1997. Total net sales of
monoclonal antibodies increased $430,000, or 3.6%, from $11.8 million in 1997 to
$12.3 million in 1998. The remaining net sales, primarily human-sourced
antibodies used in blood typing reagents and diagnostic test kits, increased
approximately $1.4 million, or 22.0%, from $6.4 million in 1997 to $7.8 million
in 1998.

GROSS PROFIT

CONSOLIDATED

     Consolidated gross profit increased 17.9%, or approximately $6.4 million,
from $35.5 million in 1997 to $41.8 million in 1998. Of this increase,
approximately $5.1 million was the result of increased sales from existing
operations, while approximately $1.3 million was attributable to acquisitions
completed during 1997 and 1998. Gross margin decreased from 36.4% in 1997 to
34.0% in 1998, largely as a result of lower than anticipated production at many
of the Company's primarily non-specialty donor centers, resulting in decreased
fixed cost absorption and lower gross profit per unit, and a changing pricing
mix of non-specialty antibody sales.

THERAPEUTIC PRODUCTS

     Gross profit from Therapeutic Products increased approximately $4.2
million, or 16.5%, from $25.4 million in 1997 to $29.6 million in 1998. This
increase was due to additional gross profit from existing operations, primarily
a result of increased sales of anti-D, offset by lower gross profit on several
product lines, most notably non-specialty antibodies, and higher depreciation
expense. Gross margin decreased from 32.0% in 1997 to 29.0% in 1998, primarily
as a result of the level of non-specialty antibody production. Gross margin was
also impacted by the increase in the percentage of non-specialty antibodies sold
on a gross basis, as there was relatively insignificant gross profit attributed
to the additional revenue.

DIAGNOSTIC PRODUCTS

     Gross profit from Diagnostic Products increased approximately $2.2 million,
or 21.7%, from $10.1 million in 1997 to $12.3 million in 1998. The majority of
this increase was attributable to increased sales from existing operations, most
notably monoclonal and polyclonal antibodies used in blood typing reagents and
increased margins on antibodies sold for use in diagnostic test kits. Gross
margin for the Diagnostic Products segment increased from 55.2% to 61.1%,
primarily as a result of a favorable sales mix within the segment's products.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

     Consolidated selling, general and administrative expenses increased 5.1%,
or $726,000, from $14.2 million in 1997 to $14.9 million in 1998. The increase
was primarily due to a general increase in corporate overhead, in particular
expenditures for information systems and related personnel, as well as legal,
accounting and other expenses related to the Company's acquisition activities.
This increase was net of a decrease in product development expenses, primarily
attributable to a reduction in expenditures relating to the development of a

                                       25
<PAGE>   28

therapeutic monoclonal anti-D product. Selling, general and administrative
expenses, as a percentage of consolidated net sales, decreased from 14.6% in
1997 to 12.2% in 1998, due to the higher average selling price for non-specialty
antibodies, which required only minimally higher general and administrative
expenses.

OTHER EXPENSE, NET

     Consolidated other expense, net, which primarily consists of amortization
of goodwill and other intangible assets and gains and losses from foreign
currency translations, was essentially unchanged from 1997 to 1998.

INTEREST INCOME, NET

     Consolidated interest income, net increased $314,000, or 59.0%, from
$532,000 in 1997 to $846,000 in 1998. The increase was primarily attributable to
higher average cash and cash equivalent balances during 1998 and lower average
borrowings outstanding during the year, offset by lower average interest rates
earned on invested cash balances.

PROVISION FOR INCOME TAXES

     The provision for income taxes as a percentage of income before income
taxes decreased from 37.1% in 1997 to 34.7% in 1998. The decrease was primarily
the result of the favorable impact of a number of foreign, state and local tax
planning initiatives adopted by the Company.

LIQUIDITY AND CAPITAL RESOURCES

     The following table sets forth certain indicators of consolidated financial
condition and liquidity of the Company as of the following fiscal year ends:

<TABLE>
<CAPTION>
                                                       1997        1998        1999

Total debt to equity ratio.........................       6.6%        4.1%       31.5%
</TABLE>

     The Company has three principal sources of near-term liquidity: (i)
existing cash and cash equivalents; (ii) cash generated by operations, and (iii)
borrowing capacity under the Company's revolving credit facility (the
"Revolver"), which provides for a maximum borrowing capacity of $75 million.
Management believes the Company's liquidity and capital resources are sufficient
to meet its working capital, capital expenditure and other anticipated cash
requirements over the next twelve months and may be available for use in
acquisitions. However, the Company anticipates that significant acquisition or
growth opportunities could require supplementary funding, including the issuance
of equity or debt securities.

     Net cash used in operating activities in 1999 was $4.8 million as compared
to $9.8 million provided by operating activities in the prior year, a decrease
of $14.6 million. This decrease was primarily attributable to an increased
investment in working capital of approximately $11.4 million versus the prior
year, decreased net income of $31.8 million, and a non-cash deferred income tax
benefit of $8.0 million in 1999 versus a deferred tax provision of $307,000 in
1998, offset by non-cash special charges of $34.0 million and $3.0 million of
additional non-cash depreciation and amortization expense. The increased
investment in working capital was primarily due to a $13.0 million larger
increase in inventory versus the prior year, primarily resulting from additional
quality assurance steps the Company implemented, which extended the inventory
cycle time.

     Net cash used in investing activities in 1999 was $41.2 million as compared
to $12.2 million in the previous year. Investing activities in 1999 consisted
primarily of $28.7 million used for the acquisition of Pentex and capital
expenditures of $16.3 million. Investing activities in 1998 consisted primarily
of the acquisition of four donor centers and a clinical trial site for aggregate
consideration of approximately $5.5 million (net of cash acquired) and $5.2
million in capital expenditures. Additionally, net cash used in

                                       26
<PAGE>   29

investing activities in 1998 was net of the receipt of approximately $878,000 in
cash for the final post closing adjustment of a 1997 acquisition.

     Capital expenditures relate primarily to the Company's facilities, related
equipment and information systems. The significant expenditures of 1999 included
expansion of the Company's protein fractionation facility located in Kankakee,
IL, development costs relating to a donor center automation system and routine
donor center expenditures including relocations and renovations. The significant
expenditures of 1998 included development costs relating to a donor center
automation system, the vast majority of which were written off in 1999 as
discussed in "-- Overview"; expansion of the Company's international
headquarters in Atlanta, Georgia; and certain donor center capital expenditures,
such as storage freezer replacements

     During 2000, the Company anticipates making capital expenditures of
approximately $10 million to $12 million, primarily comprised of (i) an
expansion of the Company's BSA manufacturing capacity at its fractionation
facility in Kankakee, Illinois; (ii) several information systems initiatives,
primarily the automation of the Company's donor center network; and (iii)
renovations or relocations of existing donor centers. In addition, the Company
expects to purchase a site in Scotland to expand its monoclonal manufacturing
operations which, if consummated, would require expenditures of approximately
$2.5 million.

     Net cash provided by financing activities in 1999 was approximately $14.4
million as compared to $5.5 million in the prior year. Financing activities in
1999 primarily consisted of borrowings under the Revolver and proceeds from the
exercise of stock options, offset by repurchases of common stock. Financing
activities in 1998 consisted primarily of proceeds from the exercise of stock
options.

     Total debt and capital lease obligations were $32.6 million at December 26,
1999, an increase of $27.3 million from December 27, 1998. The increase was
primarily due to $30 million in borrowings under the Revolver to (i) partially
finance the Company's share repurchase program, and (ii) to fund working capital
needs during the third and fourth quarters of 1999 when the Company experienced
a delay in the shipment of a significant amount of product. The increase due to
borrowings under the Revolver was offset by the conversion of a $2.7 million
principal portion of a convertible note into 213,219 shares of the Company's
common stock.

YEAR 2000

     The Year 2000 issue results from computer-based systems that use two digits
rather than four to define the applicable year. If not corrected, many computer
applications could have failed or created erroneous results after December 31,
1999.

     The Company developed and implemented a plan to achieve Year 2000
readiness. This plan's activities were intended to remediate the Year 2000 issue
for any non-compliant critical information technology ("IT") systems and non-IT
devices in use by the Company so that the Company could continue its operations
without interruption or with minimal disruption. The Company's plan also
included communication with customers, suppliers, outsource laboratories,
financial institutions and other third parties with which it has a material
relationship to determine the expected degree of their Year 2000 compliance, and
to monitor their progress towards Year 2000 readiness. The Company's Year 2000
plan included five primary phases: (1) inventory, (2) assessment, (3)
remediation, (4) testing/validation, and (5) implementation. The Company used a
risk-based analysis of its operations to identify those items that are critical
to the Company and at risk.

     As of December 31, 1999, all necessary implementation efforts were
completed. The Company is not aware of any material problems resulting from Year
2000 issues, either with its products, its internal systems, or the products and
services of third parties. While the Company does not expect any material Year
2000 issues in the future, it will continue to monitor its IT systems and those
of its suppliers and vendors to ensure that any latent Year 2000 matters that
may arise are addressed promptly. The total costs of the Company's Year 2000
compliance program were approximately $200,000.

MARKET RISK

     The Company is exposed to market risk from changes in foreign currency
exchange rates and, to a lesser extent, interest rates, which could affect its
future results of operations and financial condition. The Company manages its
exposure to these risks through its regular operating and financing activities.

  Foreign Currency Exchange Rates

     The Company's foreign-based operations are conducted primarily through its
Serologicals, Ltd. subsidiary located in the United Kingdom. In 1997, 1998 and
1999, foreign-based operations accounted for approximately 14%, 10% and 9% of
net sales and approximately 15%, 21%, and 29% of income from operations (sales
minus cost of sales and selling, general and administrative expenses),
respectively.

     The functional currency of Serologicals, Ltd. is the British pound
sterling. Fluctuations in foreign exchange rates can impact operating results,
including net revenues and expenses, when translations of the subsidiary
financial statements are made in accordance with SFAS No. 52, "Foreign Currency
Translation." Furthermore, the Company transacts business in various foreign
currencies, subjecting it to exposure from movements in the exchange rates of
those countries. However, a large portion of the Company's sales to foreign
countries is denominated in U.S. currency, thus mitigating a significant portion
of this risk. It has not been the Company's practice to hedge its assets and
liabilities in the U.K. or its intercompany transactions and, accordingly, has
not used derivatives or other off-balance sheet items to manage any significant
foreign currency exchange risk. In 1997, 1998 and 1999, the Company recorded
foreign currency transaction gains (losses) of approximately ($10,000),
($76,000), and $240,000, respectively.

  Interest Rates

     The Company's outstanding indebtedness as of December 26, 1999 is comprised
primarily of $30 million outstanding under the Revolver, and a convertible note
payable with an outstanding balance of approximately $2.6 million. The Revolver
was comprised of a $20 million, 30-day LIBOR-based loan bearing interest at
LIBOR plus 1.25%, or 6.84% and a $10 million 30-day LIBOR-based loan bearing
interest at LIBOR plus 1.25%, or 7.72%. The convertible note bears interest at a
fixed rate of 4.0%. Due primarily to the relatively short duration of
obligations outstanding under the Company's revolving credit facility, the
Company does not believe it has a material exposure to fluctuations in interest
rates.

OUTLOOK

  Therapeutic Products

     Demand for non-specialty antibodies remains strong and generally exceeds
the Company's ability to supply targeted amounts to its customers. However, the
Company expects continued margin pressure on this product line unless and until
it is able to increase its collections of this product and its selling prices to
its customers. Furthermore, the Company believes that the non-specialty antibody
business may no longer match its primary strategic objectives of providing high
margin, value-added products to the pharmaceutical, biotechnology and diagnostic
industries. As a result, the Company has been performing a strategic review of
its non-specialty operations, and is in discussions that could result in a
divestiture of all or a portion of its 47 non-specialty donor centers. However,
there can be no assurance that the Company will be successful in any of these
efforts, including divesting or otherwise successfully restructuring its
non-specialty operations, or that any further impact from the factors affecting
the business will not have a material adverse effect on the Company or its
operations.

     The Company expects a modest recovery in anti-D sales in 2000. However,
further operational adjustments may be required, including reducing the level of
anti-D specialty antibody collections, which could adversely affect the per unit
production costs of anti-D and other specialty therapeutic products.

     Demand for the Company's other specialty antibody products, anti-HBs and
anti-rabies, continues to be strong and is expected to increase in 2000. The
Company believes that the demand for anti-HBs may exceed

                                       28
<PAGE>   31

its current production capabilities and is pursuing various strategies to
increase production at its 17 specialty donor centers.

  Diagnostic Products

     The Company anticipates moderate increases in sales of polyclonal
antibodies used in blood typing reagents and diagnostic test kits, and more
substantial increases during 2000 in sales of monoclonal antibodies, primarily
as a result of the potential of the outsource manufacturing work the Company is
performing for a major diagnostic customer. The Company expects demand for its
Pentex(R) line of blood protein products, in particular the EX-CYTE(R) line of
tissue culture media, to continue to increase. During 1999, the Company
completed a $13 million expansion of its manufacturing facilities in Kankakee,
Illinois that is dedicated to the manufacture of EX-CYTE(R). The Company is also
currently undergoing a $2 million expansion of the Pentex(R) bovine serum
albumin (BSA) manufacturing operations, which it expects to complete during the
latter part of 2000. This expansion is expected to increase BSA production
capacity by approximately 30%, in order to meet current and expected customer
demand.

     The Company is developing a line of monoclonal antibodies to be used as
controls in diagnostic test kits, which were historically derived from human
donors. While sales to date have not been significant, the Company believes that
this product line could provide additional opportunities for growth in
Diagnostic Products.

     The Company believes that in addition to the aforementioned internal growth
potential, opportunities exist to expand its diagnostic operations through
selective acquisitions that are complementary to its existing monoclonal and
protein fractionation operations. However, there can be no assurance that the
Company will be successful in achieving any or all of the elements of its
strategy.

     The industries in which the Company operates are subject to strict
regulation and licensing by the FDA. Similar or more restrictive regulation
exists in many of the states and foreign countries where the Company and its
customers conduct business. Changes in existing federal, state or foreign laws
or regulations could have an adverse effect on the Company's business. See Item
1.-Business-"Government and Industry Regulation".

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("SFAS No.133"). SFAS No. 133 requires
derivative instruments to be recorded on the balance sheet as assets or
liabilities, measured at fair value. Gains or losses resulting from changes in
values of derivatives would be accounted for depending on the use of the
derivative and whether it qualifies for hedge accounting. In June 1999, the FASB
issued Statement of Financial Accounting Standards No. 137, which defers the
effective date of SFAS No. 133 to fiscal years beginning after June 15, 2000.
The Company does not believe that the adoption of SFAS No. 133 will have a
material effect on its results of operations and financial position.

     In December 1999, the Securities and Exchange Commission issued SAB No.
101. This statement summarizes certain staff views in applying generally
accepted accounting principles to revenue recognition in financial statements.
SAB No. 101 provides additional guidance regarding when revenue is realized,
earned and properly recognized. As part of its assessment of its compliance with
SAB 101, the Company determined that its revenue recognition policy as it
related to the timing of recording sales under an existing arrangement with a
single customer of its Serologicals Proteins subsidiary should be amended. As a
result, the Company has restated its unaudited results of operations for the
second and third quarters of 1999. See Note 15 to Notes to Consolidated
Financial Statements.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Serologicals Corporation:

     We have audited the accompanying consolidated balance sheets of
SEROLOGICALS CORPORATION (a Delaware corporation) AND SUBSIDIARIES as of
December 27, 1998 and December 26, 1999 and the related consolidated statements
of income (loss), stockholders' equity and cash flows for each of the three
fiscal years in the period ended December 26, 1999. 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 auditing standards generally
accepted in the United States. 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 Serologicals Corporation and
subsidiaries as of December 27, 1998 and December 26, 1999 and the results of
their operations and their cash flows for each of the three fiscal years in the
period ended December 26, 1999 in conformity with accounting principles
generally accepted in the United States.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
           DECEMBER 28, 1997, DECEMBER 27, 1998 AND DECEMBER 26, 1999

1. ORGANIZATION AND BUSINESS OPERATIONS

     Serologicals Corporation (a Delaware corporation) (together with its
subsidiaries, the "Company") is a leading worldwide provider of specialty human
antibodies, monoclonal antibodies, non-specialty antibodies and animal blood
proteins to major healthcare companies. The Company's products are generally
further manufactured by its customers into therapeutic products for the
treatment of diseases such as Rh incompatibility in newborns, rabies and
hepatitis and in diagnostic products such as blood typing reagents and
diagnostic test kits and as cell culture additives for biotechnology products.

     The Company operates a national network of 64 donor centers, 17 of which
specialize in the collection of specialty antibodies and 47 of which primarily
collect source plasma containing non-specialty antibodies from which a number of
therapeutic products, primarily intravenous immune globulin ("IVIG"), are
derived. The Company also operates laboratories in the United States and in
Scotland, two U.S. Food and Drug Administration ("FDA") licensed monoclonal
antibody manufacturing facilities in Scotland and a registered protein
fractionation facility in Kankakee, Illinois.

     Owing in part to increasing margin pressures and the inability of the
Company to pass increased costs on to its customers, the Company has been
performing a strategic review of its non-specialty antibody operations, and is
in discussions which could result in a divestiture of all or a portion of its 47
non-specialty donor centers.

     The industries in which the Company operates are subject to strict
regulation and licensing by the FDA and similar regulatory bodies in many of the
states and foreign countries where the Company or its customers conduct
business. Changes in existing federal, state or foreign laws or regulations
could have an adverse effect on the Company's business.

     The industry in which the Therapeutic Products segment (Note 14) operates
is also characterized by sales to a relatively few major healthcare companies.
One of the Company's customers, Bayer Corporation ("Bayer"), accounted for
approximately 41% of the Company's net sales in 1999 (Note 14). The Company has
four five-year supply contracts with Bayer for the sale of non-specialty
antibodies that accounted for approximately 27% of the Company's net sales in
1999, three of which expired in 1999 and have been extended on an interim basis,
and one which will expire in 2002. There can be no assurance that the contracts
will not be terminated, that Bayer will not materially change its supply
requirements pursuant to the agreements or that the contracts will be renewed
beyond their current terms.

     Export sales from the United States represented approximately 15% of net
sales in 1999, and foreign sales originating in the United Kingdom accounted for
an additional 8% of net sales (Note 14). Concern over the safety of blood
products has led to movements in a number of countries, particularly those in
western Europe, to restrict the importation of blood and blood derivatives
collected outside the countries' borders or, in the case of certain European
countries, outside Europe. To date, these efforts have not led to any meaningful
restriction on the importation of blood and blood derivatives and have not
adversely affected the Company. However, there can be no assurance that the
impact of these or other efforts will not have a material adverse effect on the
Company or its operations.

     The business conducted by the Therapeutic Products segment is highly
dependent upon the Company's ability to attract and retain qualified donors. A
portion of the industry's potential donor population has been disqualified due
in large part to more rigorous testing and screening procedures required by
regulatory authorities, industry trade associations and the Company's customers.
The potential donor population with certain naturally occurring specialty
antibodies has also decreased due to aging and attrition. The inability to
maintain and replenish its donor base could adversely affect the Company.

     The Company generates significant sales outside the United States and is
subject to risks generally associated with international operations. The
Company's Serologicals, Ltd. subsidiary, formerly known as

                                       F-7

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Bioscot, Ltd. ("Bioscot"), which accounted for approximately 9% of the Company's
net sales in 1999, generates net sales and incurs expenses in foreign
currencies. Accordingly, the Company's financial results from international
operations may be affected by fluctuations in currency exchange rates.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Basis of Presentation

     The accompanying consolidated financial statements include the accounts of
the Company and its wholly-owned subsidiaries. All significant intercompany
accounts and transactions have been eliminated in consolidation. The Company's
fiscal period end for financial reporting purposes is the last Sunday of each
period.

     Certain prior year amounts have been reclassified to conform to the current
year presentation.

  Use of Estimates

     The preparation of these consolidated 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.

  Inventories

     Inventories are stated at the lower of cost or market, cost being
determined on a first-in, first-out basis. Market for product inventories is net
realizable value and for supplies is replacement cost.

     Inventories at December 27, 1998 and December 26, 1999 consisted of the
following (in thousands):

</TABLE>

  Property and Equipment

     Property and equipment are stated at cost and are depreciated using the
straight-line method over their estimated useful lives for financial reporting
purposes. For income tax purposes, the Company uses accelerated depreciation
methods. Depreciable lives for equipment, furniture and fixtures range from
three to ten years. Leasehold improvements are amortized over the shorter of the
lease term or the economic lives of the assets. Buildings and improvements are
depreciated over lives ranging from 20 to 32.5 years. Expenditures for
maintenance and repairs are charged to expense as incurred.

     During 1999, the Company prospectively adopted Statement of Position 98-1,
"Accounting for the Costs of Computer Software Developed or Obtained for
Internal Use." This standard requires certain direct development costs
associated with internal-use software to be capitalized, including external
direct costs of material and services and payroll costs for employees devoting
time to the software projects. Costs incurred during the preliminary project
stage, as well as for maintenance and training are expensed as incurred. This
standard currently applies to certain costs of the Company's donor center
automation project; however, as of December 26, 1999, the impact of adopting
this accounting standard was not material to the Company's financial position or
results of operations.

expenditures relating to the development of a donor center management
information system and capital expenditures relating to the further expansion of
the Company's international headquarters in Atlanta, Georgia.

     The Company capitalizes interest expense as part of the cost of
construction of facilities and equipment for its own use. Interest expense
capitalized in 1999 in connection with the expansion of the Company's protein
fractionation facility was $118,000.

  Revenue Recognition and Deferred Revenue

     The Company's policy is to record revenue upon the shipment of its
products. On occasion, the Company receives advance payments from customers for
future delivery of specified products. The revenue related to these advance
payments is deferred until the specified products are shipped.

  Cash Equivalents

     For financial reporting purposes, the Company considers all investments
purchased with an original maturity of three months or less to be cash
equivalents.

  Investments

     The Company held certain investments in marketable securities as of
December 27, 1998 that were sold in fiscal 1999. The Company considered such
investments to be available-for-sale; therefore the unrealized gain or loss on
such investments was reported as a component of accumulated other comprehensive
income within stockholders' equity. As of December 27, 1998, these investments
were recorded as other current assets in the accompanying consolidated balance
sheets.

  Foreign Operations

     The financial statements of Bioscot have been translated into U.S. dollars
in accordance with Statement of Financial Accounting Standards ("SFAS") No. 52,
"Foreign Currency Translation" ("SFAS No. 52"). Under SFAS No. 52, all balance
sheet accounts are translated at the exchange rate at year-end. Income statement
items are translated at the average exchange rate for the year. Translation
adjustments are not included in determining net income (loss) but are
accumulated and reported as a component of stockholders' equity and
comprehensive income (loss). Gains and losses, which result from foreign
currency transactions, are included in the accompanying consolidated statements
of income (loss).

  Goodwill and Other Intangible Assets

     Goodwill

     The excess of cost over the fair market value of the net assets acquired
("goodwill") is being amortized on a straight-line basis over periods ranging
from 13 to 25 years. The goodwill relates primarily to the acquisition of donor
centers and the acquisition of Pentex (Note 5).

     In determining whether goodwill is recoverable, the Company periodically
reviews the carrying values assigned to goodwill and other intangible assets
based upon expectations of undiscounted future cash flows from the use and
eventual disposition of the underlying assets. During the third quarter of 1999
and pursuant to the provisions of SFAS No. 121, "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to be Disposed Of" ("SFAS No.
121"), the Company performed a recoverability review of its long-lived assets
relating to its non-specialty antibody business. While the review indicated that
no impairment existed, the Company determined that the useful lives used for
amortizing goodwill and other acquired intangible assets relating to its
non-specialty antibody business were no longer applicable. As a result, the
Company reduced the useful lives for amortizing the related goodwill and FDA
licenses from 25 years to 13 years. The impact of this change was an increase in
amortization expense for the year ended December 26, 1999 of $716,000.

     Based on new information regarding the expected future cash flows of the
non-specialty antibody business, the Company reevaluated the recoverability
review it had performed in the third quarter. In connection with this
reevaluation, the Company recorded a $24.9 million impairment loss to write down
long-lived assets used in its non-specialty antibody business to their estimated
fair value. (Note 3), as the carrying value of such assets exceeded their
expected undiscounted future cash flows.

     Debt Issuance Costs

     In connection with the amendment of its revolving credit facility (Note 8),
the Company incurred certain costs. Such amounts were capitalized and are being
amortized to interest expense over three years, the term of the related
facility.

     FDA Licenses

     In connection with the acquisitions of donor centers (Note 5), the Company
acquired the related licenses of the FDA-approved donor centers. The estimated
fair values of the FDA licenses are capitalized and

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

amortized on a straight-line basis over a period of 13 to 25 years. During the
third quarter of 1999, the Company reduced the useful lives used to compute
amortization expense for the FDA licenses of its non-specialty antibody business
from 25 years to 13 years. The impact of this change was an increase in
amortization expense for the year ended December 26, 1999 of $68,000.

     Non-Compete Agreements

     In connection with certain of its acquisitions (Note 5), the Company
entered into non-compete agreements with the sellers. Such agreements are
recorded at their estimated fair market value and are being amortized on a
straight-line basis over the terms of the respective agreements, which range
from three to five years.

     The consolidated amortization expense of all intangible assets was
$2,680,000, $2,805,000 and $4,522,000 in 1997, 1998 and 1999, respectively.

     The following table sets forth the gross balance and accumulated
amortization of all intangible assets as of December 27, 1998 and December 26,
1999 (in thousands):

     Earnings (Loss) Per Share

     Basic earnings (loss) per share are calculated by dividing net income
(loss) by the weighted average number of common shares outstanding during the
period. The calculation of the Company's diluted earnings (loss) per share is
similar to basic earnings (loss) per share, except that net income is adjusted
by the after-tax interest expense on convertible indebtedness and the weighted
average number of shares includes the dilutive effect of stock options,
warrants, convertible indebtedness and similar instruments. As the Company
incurred a loss in 1999, diluted shares outstanding excludes all potentially
dilutive securities, as their inclusion would have been anti-dilutive.

     All share and per share data included herein have been adjusted to reflect
the three-for-two stock splits effected in February of 1997 and August of 1998
(Note 6).

     The diluted earnings per share calculation for 1998 excludes the effect of
562,500 shares issuable upon the conversion of certain indebtedness and 26,250
shares issuable upon the exercise of stock options, respectively, as their
inclusion would have been anti-dilutive. The diluted loss per share calculation
for 1999 excludes the potentially dilutive effect of options and warrants to
purchase approximately 4.2 million shares of the Company's common stock, and
approximately 182,000 shares issuable upon the conversion of certain
indebtedness, as the Company incurred a loss and their inclusion would have been
anti-dilutive.

     Stock-Based Compensation Plans

     The Company accounts for its stock-based compensation plans under
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB No. 25"). The Company applies SFAS No. 123, "Accounting for
Stock-Based Compensation" ("SFAS No. 123") for disclosures of its stock-based
compensation plans. SFAS No. 123 requires that companies that do not choose to
account for stock-based compensation as prescribed by the statement shall
disclose the pro forma effects on earnings and earnings per share as if SFAS No.
123 had been adopted as of January 1, 1995. Additionally, certain other
disclosures are required with respect to stock compensation and the assumptions
used to determine the pro forma effects of SFAS No. 123 (Note 7).

     Recent Accounting Pronouncements

     In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
No.133"). SFAS No. 133 requires derivative instruments to be recorded on the
balance sheet as assets or liabilities, measured at fair value. Gains or losses
resulting from changes in values of derivatives would be accounted for depending
on the use of the derivative and whether it qualifies for hedge accounting. In
June 1999, the FASB issued SFAS No. 137, which defers the effective date of SFAS
No. 133 to fiscal years beginning after June 15, 2000. The Company does not

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

believe that the adoption of SFAS No. 133 will have a material effect on its
results of operations and financial position.

3. SPECIAL CHARGES

     The effect of the following items was recorded in 1999 and is reflected in
the accompanying Consolidated Statements of Income (Loss) under the caption
"Special Charges":

     Primarily as a result of a continuing strategic review of the business
conducted at its 47 non-specialty donor centers, during 1999 and pursuant to the
requirements of SFAS No. 121, the Company performed a review of the
recoverability of its long-lived assets relating to this business (Note 2). As a
result, the Company determined that an impairment loss had been incurred as of
December 26, 1999 as the expected undiscounted future cash flows of the
non-specialty business were less than the current carrying values of the assets.
During the fourth quarter of 1999, the Company recorded a non-cash impairment
charge of $24.9 million to write down the assets to their estimated fair market
value, which was determined in part through an ongoing competitive bidding
process for a possible sale of the business. The operations and assets of the
non-specialty antibody business are included in the Therapeutic Products
operating segment (Note 14).

     During 1999, the Company was notified by one of its customers that certain
of the Company's shipments of anti-D antibodies in the prior year had included
several units of plasma that did not meet this customer's exact product
specifications. The customer indicated to the Company that the units had been
partially manufactured with other units of plasma and thus had affected a
substantial number of other units. The Company agreed to reimburse this customer
for their cost of the product and recorded a liability and related expense in
the amount of approximately $2.0 million. The liability was settled during the
first quarter of fiscal year 2000. The Company is pursuing reimbursement of this
claim from its product and professional liability insurance carrier. However,
the Company is currently unable to determine the amount of reimbursement, if
any, it may receive from the carrier.

     In the third quarter of 1999, the Company recorded a non-cash expense of
$1.2 million to write down its clinical trial site to its estimated fair market
value. In December of 1999, the Company divested substantially all of the assets
of this site. In connection therewith, the Company recorded an additional loss
on the transaction in the amount of $117,000. The operations of the clinical
trial site were included in the Corporate/ Other operating segment (Note 14).

     During 1999, the Company terminated a contract with a third party software
vendor that had been developing a custom donor center operating system, in favor
of an alternative vendor. A result of this decision, in the third quarter the
Company wrote off approximately $4.2 million of previously capitalized costs.
These assets were included in the Therapeutic Products segment.

     During 1999, the Company's chief executive officer resigned from that
position and as a director of the Company. The Company entered into separation
arrangements with this individual, its chairman of the board and approximately
12 other corporate-based employees. The Company recorded an expense of
approximately $1.6 million to cover the costs of the separation benefits payable
to these individuals. As of December 26, 1999, the Company had paid
approximately $187,000 of these benefits, leaving an accrual balance of
approximately $1.4 million; no other adjustments were made to the accrual during
1999.

4. SALES OF COMMON STOCK

     In September 1997, the Company sold 1,425,000 shares of its common stock,
at a price of $13.00 per share, to institutional investors in a private
placement transaction made in reliance upon the exemption from the registration
requirements of the Securities Act of 1933, as amended, afforded by Section 4(2)
thereof. The net proceeds to the Company from the sale of the shares were
approximately $17.5 million and were used for general corporate purposes,
including acquisitions.

5. ACQUISITIONS

     In March 1997, the Company acquired Nations Biologics, Inc. and its
affiliated companies (the "Nations Group") for approximately $14.2 million,
before recording transaction costs and before certain purchase price
adjustments. The initial purchase price consisted of approximately $10.2 million
of cash and the issuance to one of the sellers of a $4.0 million convertible
subordinated promissory note with an original maturity of March 7, 2002 (the
"Nations Note"). The Company financed the $10.2 million of cash paid at closing
with cash on hand. During 1998, the Company received approximately $878,000 for
payment of all post-closing adjustments. The Nations Group operated 16 donor
centers that primarily collect non-specialty antibodies.

     In September 1997, the Company acquired all of the outstanding capital
stock of Bio-Lab, Inc. and Med-Lab, Inc. (collectively, "Bio-Lab") for $8.5
million, before recording transaction costs. The purchase price consisted of
$5.95 million in cash and the issuance to one of the sellers of a $2.55 million
convertible subordinated promissory note due September 23, 2000 (the "Bio-Lab
Note"). The Company financed the $5.95 million of cash paid at closing with cash
on hand.

     During 1998, the Company purchased the assets of four non-specialty donor
centers and the assets of a clinical trial site in two separate transactions for
aggregate consideration of approximately $5.5 million (net of cash acquired).
Each of the 1997 and 1998 acquisitions was accounted for as a purchase in
accordance with APB No. 16, and accordingly, the purchase price has been
allocated to the net assets acquired based on the fair values as of the
acquisition date. The excess of the cost over the estimated fair value of the
net assets acquired has been allocated to goodwill and certain other
identifiable intangible assets. During 1999, the Company divested the clinical
trial site (Note 3).

     On December 29, 1998, the Company purchased substantially all of the assets
of the Pentex Blood Proteins business of Bayer Corporation ("Pentex," renamed
"Serologicals Proteins" by the Company). The purchase price was $29 million,
before transaction costs and subject to adjustment based on the closing net
assets, as defined, of the acquired business as of the closing date. The
acquisition of Pentex was accounted for as a purchase in accordance with APB No.
16 and, accordingly, the purchase price has been preliminarily allocated to the
net assets acquired based on the fair values as of the acquisition date. The
excess of the cost over the estimated fair value of the net assets acquired has
been preliminarily allocated to goodwill and certain other identifiable
intangible assets, which totaled approximately $18.9 million and which is being
amortized over a weighted-average life of 22 1/2 years. Pentex is engaged in the
research, manufacturing, marketing and sale of a full line of high quality
purified blood protein products primarily to customers in the diagnostics and
biopharmaceutical industries in the United States and approximately 25 other
countries worldwide. The Company funded the acquisition with cash on hand.

     The following unaudited data summarize the pro forma results of operations
for the year ended December 27, 1998 as if the acquisition of Pentex had
occurred on the first fiscal day of such period. Pro forma results of operations
for the year ended December 26, 1999 are not presented herein as the results of
operations for the two days subsequent to the Company's 1998 fiscal year end and
prior to the acquisition of Pentex are immaterial to the Company. The unaudited
pro forma information has been prepared for comparative purposes only and does
not purport to represent what the results of operations would actually have been
had the transaction actually occurred on the date indicated, or what the results
of operations may be in the future (in thousands, except per share data).

6. STOCKHOLDERS' EQUITY

  Stockholder Rights Plan

     On July 26, 1999, the Board of Directors adopted a stockholder rights plan
(the "Rights Plan"), pursuant to which one preferred stock purchase right (a
"Right") was distributed for each outstanding share of common stock held of
record on August 25, 1999. Each Right represents a right to purchase, under
certain circumstances, one one-thousandth ( 1/1000) of a share of a new series
of preferred stock at an exercise price of $45.00. If any person or group
acquires 15% or more of the common stock of the Company (except in transactions
approved by the board of directors of the Company in advance), each Right will
then entitle its holder, other than the person or group owning 15% or such other
persons or groups, to acquire, at the exercise price, the Company's common stock
with a market value equal to twice the exercise price. The Company may elect,
however, to exchange a newly issued share of the Company's common stock for each
Right. If any person or group owns 15% or more of the Company's common stock,
and the Company is acquired in a merger or other business combination, or if 50%
of its earning power or assets are sold, each Right will entitle its holder,
other than the person or group owning 15%, to acquire, at the exercise price,
shares of the acquiring company's common stock with a market value of twice the
exercise price.

     Persons owning 15% or more of Company's common stock on the date the plan
was adopted were exempt, so long as they do not acquire an additional number of
shares greater than 2% of the outstanding shares, other than in a transaction
approved by the Board of Directors of the Company in advance. The Rights expire
on August 2, 2009.

  Stock Splits

     In February 1997, the Company's Board of Directors approved a 3-for-2 stock
split effected in the form of a stock dividend, whereby each shareholder of
record as of February 10, 1997 received on February 28, 1997 one-half additional
share of common stock for each share owned as of the record date.

     In July 1998, the Company's Board of Directors approved a 3-for-2 stock
split effected in the form of a stock dividend, whereby each shareholder of
record as of July 31, 1998 received on August 14, 1998 one-half additional share
of common stock for each share owned as of the record date.

     All share and per share amounts herein have been restated to reflect these
stock splits. Additionally, common stock and additional paid-in capital amounts
have been restated to reflect the issuance of the additional shares.

  Common Stock Warrant

     In connection with a bank credit agreement entered into in 1993, the
Company issued warrants to the bank to purchase 332,436 shares of the Company's
common stock at an exercise price of $1.53 per share. The warrants are currently
exercisable and expire on March 9, 2003. As of December 26, 1999, warrants to
purchase 118,750 shares of common stock remained outstanding.

  Capital Stock

     Under the terms of its amended and restated articles of incorporation, the
Company has authorized 50,000,000 shares of common stock and 1,000,000 shares of
preferred stock that may contain such preferences and rights as determined by
the Company's Board of Directors.

  Common Stock Repurchases

     During April 1999, the Company's Board of Directors authorized the
repurchase of up to $20 million of the Company's common stock, subject to market
conditions, prevailing stock prices and the Company's capital resources. The
Company has funded repurchases and expects to fund any future repurchases with
existing cash balances, cash flow from operations and availability under the
Revolver (Note 8). As of December 26, 1999, the Company had repurchased
approximately 2.6 million shares of its common stock for aggregate consideration
of approximately $17.0 million.

7. STOCK COMPENSATION PLANS

  Officer Stock Options

     During March 1993, the Company entered into an employment agreement with
its former chief executive officer. As part of the agreement, the officer was
granted two options to purchase shares of the Company's common stock. Under each
option, the officer could purchase up to 378,000 shares of common stock at an
exercise price of $1.53 per share, the estimated fair value on the date of
grant. During December 1994, the officer was granted additional options to
purchase 345,357 shares of common stock at an exercise price of $2.45 per share,
the estimated fair market value on the date of grant. All of these options have
a term of ten years and became fully vested as of the initial public offering
date of June 14, 1995. As of December 26, 1999, options to purchase 838,857
shares of common stock were outstanding.

  Second Amended and Restated 1994 Omnibus Incentive Plan

     The Company's Second Amended and Restated 1994 Omnibus Incentive Plan (the
"Omnibus Plan") provides for the issuance of up to 4,875,000 stock options to
key employees and directors. Options granted under the Omnibus Plan can have
varying terms as determined by the Board of Directors. Options granted through
1999 under the Omnibus Plan generally vest ratably over three to four years or
in full after three years and have terms of six to ten years. Certain option
grants have been eligible for accelerated vesting upon the Company's achievement
of certain predetermined performance objectives that are approved by the
Compensation Committee of the Company's Board of Directors. As of December 26,
1999, options to purchase 2,694,988 shares were outstanding under the Omnibus
Plan, 1,352,689 of which were exercisable. As of December 26, 1999, the Company
had 1,184,270 options available for grant.

  Amended and Restated 1995 Non-Employee Director Stock Option Plan

     The Company's Amended and Restated 1995 Non-Employee Directors' Stock
Option Plan (the "Director Plan") provides for the issuance of up to 810,000
stock options to non-employee directors. Pursuant to the Director Plan, each
person who becomes a non-employee director of the Company is automatically
granted an option to purchase 36,000 shares of the Company's common stock on the
date of adoption or on the

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

day after such person's first election to the Board of Directors. The exercise
price of the options is the fair market value of the common stock on the date of
grant. In addition, the Director Plan provides for the automatic grant of
options to purchase 9,000 shares of common stock on an annual basis to each non-
employee director of the Company after the initial 36,000 share option grant has
vested in full. Options granted since 1996 under the Director Plan typically
vest over a four-year period, while options granted prior to that were fully
vested upon issuance. As of December 26, 1999, options to purchase 314,625
shares were outstanding under the Director Plan, 176,250 of which were
exercisable. As of December 26, 1999, the Company had 405,000 options available
for grant under the Director Plan.

  Employment Stock Options

     During 1997, the Company entered into employment agreements with four
individuals. As an integral part of these agreements, the individuals were
granted options to purchase an aggregate of 613,125 shares of the Company's
common stock. The options were each issued with an exercise price equal to the
fair market value of the Company's common stock on the date of grant. Each of
the options has a term of ten years, vests ratably over a four-year period and
contains other terms and conditions similar to options issued under the Omnibus
Plan. As of December 26, 1999, options to purchase 259,625 shares were
outstanding, 124,625 of which were exercisable.

  Employee Stock Purchase Plan

     Pursuant to the terms of the Company's 1996 Employee Stock Purchase Plan
(the "Purchase Plan"), eligible employees are able to purchase up to 562,500
shares of the Company's common stock through a payroll deduction program.
Employees may have up to 25% of their compensation withheld to purchase shares
at a price equal to 85% of the lower of the closing price on the first or last
day of each successive three month purchase period. As of December 26, 1999,
approximately 55,000 shares had been acquired pursuant to the Purchase Plan.

  Accounting for Stock Plans

     The Company uses the intrinsic value-based method to account for its stock
plans, as provided by APB No. 25. Accordingly, no compensation expense has been
recognized for grants of stock options as all options were issued at their fair
market value on the date of the respective grants, or in the case of options
granted prior to the Company's initial public offering, their estimated fair
market value. Had compensation expense for the Company's stock-based
compensation plans been determined in accordance with the provisions of SFAS No.
123, the Company's net income (loss) and earnings (loss) per share would have
been in the pro forma amounts indicated below (in thousands, except per share
amounts):

<TABLE>

  As reported........................................  $  0.51    $  0.63    $  (0.65)
  Pro forma..........................................     0.40       0.54       (0.79)
</TABLE>

     The pro forma amounts reflected above are not representative of the effects
on reported net income in future years as SFAS No. 123 does not apply to grants
made prior to January 1, 1995 and additional awards are generally made each
year.

     Under SFAS No. 123, the fair value of stock-based awards is calculated
through the use of option-pricing models, even though such models were developed
to estimate the fair value of freely tradable, fully transferable options
without vesting restrictions, which differ significantly from the Company's
stock option grants. These models also require subjective assumptions, including
future stock price volatility and expected lives of each option grant. The fair
value for each option grant was estimated on the grant date using the
Black-Scholes option-pricing model with the following weighted-average
assumptions:

                                                              1997    1998    1999

Risk-free interest rate.....................................  6.22%   5.45%   5.29%
</TABLE>

     Using these assumptions, the weighted average fair value of all options
granted in 1997, 1998 and 1999 was $6.51, $11.02 and $11.52 respectively.

     The Company has a revolving credit facility with a syndicate of commercial
banks (the "Revolver") that was amended during 1999 to increase the total
maximum capacity from $35 million to $75 million. The Revolver is payable in
full on September 28, 2002 and bears interest at either a floating rate or
Eurodollar interest rate plus a margin that fluctuates based on the Company's
leverage ratio. The margin on the Eurodollar rate ranges from 1.25% to 2.0%, and
the margin on the floating rate option ranges from 0% to .5%. At December 26,
1999, the outstanding principal balance under the Revolver bore interest at
rates ranging from 6.84% to 7.72%. The Company is required to pay a fee ranging
from .3% to .5%, depending on the Company's leverage, on the unused portion of
the Revolver. The Revolver is secured by substantially all of the assets of the
Company and the stock of its domestic subsidiaries. The Revolver also contains
certain financial covenants that require the maintenance of minimum levels of
cash flow coverage, debt service coverage and debt to net worth and also
provides for maximum levels of debt to cash flow and rent expense. Furthermore,
under the terms of the Revolver, there are limitations on the Company's ability
to pay cash dividends and to repurchases shares of the Company's common stock.
As of December 26, 1999, the Company was in compliance with all debt covenants.

     In connection with the acquisition of the Nations Group, the Company issued
one of the sellers the Nations Note, with an original maturity of March 7, 2002.
The Nations Note bore interest at a rate of 4.5% per annum through the earlier
of the date of repayment, conversion or March 7, 2000. Under its original terms,
on or after March 7, 1998, 1999 and 2000, the payee could call for repayment (or
conversion into shares of the Company's common stock) one-third, two-thirds and
all, respectively, of the then outstanding principal amount of the Nations Note,
subject to certain restrictions as to minimum amounts and frequency. The Nations
Note was convertible at the option of the holder at a conversion price of $12.51
per share, the fair market value of the Company's common stock at the date of
issuance. The Company had the right to call the Nations Note at any time
commencing March 7, 2000, or earlier if certain events occur. During 1998 and
pursuant to the terms of the related note agreement, the holder of the Nations
Note opted to convert $1.3 million principal amount of the Nations Note into
106,608 shares of the Company's common stock. During 1999, the Company and the
payee agreed to amend the Nations Note, allowing the holder to call for
repayment (or conversion into shares of the Company's common stock), the
remaining outstanding principal balance of the Nations Note. During 1999, the
remaining outstanding principal balance of approximately $2.7 million was
converted into 213,219 shares of the Company's common stock.

     In connection with the acquisition of Bio-Lab, the Company issued one of
the sellers the Bio-Lab Note, which bears interest at a rate of 4.0% per annum
through the earlier of the date of repayment, conversion or its

maturity on September 23, 2000. Commencing September 23, 1999, the Bio-Lab Note
may be prepaid, in whole or in part, upon not less than thirty days prior
written notice by the Company. The Company may also prepay the note prior to
September 23, 1999, in whole or in part, at a premium to the then outstanding
principal balance if certain events occur. On or after September 23, 1998, 1999
and 2000, the payee may call for repayment (or conversion into shares of the
Company's common stock) one-third, two-thirds and all, respectively, of the then
outstanding principal amount of the Bio-Lab Note, subject to certain
restrictions as to minimum amounts and frequency. The Bio-Lab Note is
convertible at the option of the holder at a conversion price of $13.98 per
share, the fair market value of the Company's common stock at the date of
issuance.

     Future maturities of long-term debt and capital lease obligations at

  Operating Leases

     The Company leases certain office space, donor centers, laboratory and
manufacturing facilities and laboratory and other equipment under non-cancelable
operating lease agreements. Future minimum annual rental obligations under the
non-cancelable portion of operating leases as of December 26, 1999 were as

     Rent expense was approximately $3,297,000, $3,871,000, and $4,959,000
during 1997, 1998 and 1999, respectively.

  Supply Contracts

     The Company is a party to several long-term agreements for the sale of
non-specialty antibodies to three customers at specified prices that are
typically renegotiated annually. The contracts generally include escalating
minimum annual purchase amounts by the customers subject to the rights of such
customers to reduce the amounts purchased under certain terms. The Company
expects to meet its obligations under the supply contracts.

  Product Claims

     During 1999, the Company discovered and notified a customer that it had
inadvertently shipped a unit of source plasma that did not meet FDA standards
requiring negative test results for a certain virus. The

                                      F-20

                   SEROLOGICALS CORPORATION AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

customer has indicated to the Company that the product has been partially
manufactured with other units of plasma and thus has potentially affected a
substantial number of units. However, the customer has notified the Company that
the manufacturing pool containing this unit has tested negative for the
particular virus, and therefore may be available for further manufacture into
finished product. While the customer is seeking FDA approval for the use of this
product, it has indicated that absent such approval it will seek recovery from
the Company for up to $1.6 million of costs and damages it has incurred. As the
Company is unable to determine the probability of damages, if any, for which it
may ultimately be responsible, no liability has been recorded as of December 26,
1999.

  Litigation

     The Company is involved in certain litigation arising in the ordinary
course of business. In management's opinion, the ultimate resolution of these
matters will not have a material adverse effect on the Company's financial
position or results of operations.

10. DISCLOSURE ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

  Cash Equivalents

     The Company estimates that the fair value of cash equivalents approximates
carrying value due to the short maturity of these instruments.

  Notes Payable

     The Company estimates that the fair values of borrowings under the Revolver
approximate their carrying value due to their floating interest rates and
relatively short maturities. The Company estimates that the fair value of notes
payable approximates carrying value based upon its estimated current borrowing
rate for issuance of debt with similar terms and remaining maturities.

     Disclosure about the estimated fair value of financial instruments is based
on pertinent information available to management as of December 27, 1998 and
December 26, 1999. Although management is not aware of any factors that would
significantly affect the reasonable fair value amounts, such amounts have not
been comprehensively revalued for purposes of these financial statements since
the periods presented and current estimates of fair value may differ
significantly from the amounts presented herein.

11. INCOME TAXES

taxable income.

     The Company's ten largest customers accounted for approximately 84%, 84%
and 78% of total net sales for the years ended December 28, 1997, December 27,
1998 and December 26, 1999, respectively. Customers making up greater than 10%
of net sales of the Company during such periods are as follows:

</TABLE>

---------------
* Less than 10%.

     The Therapeutic Products segment generated all sales to Bayer during 1997
and 1998. During 1999, 97% of the sales to Bayer were generated from the
Therapeutic Products segment (Note 14), while the remaining sales were generated
by the Diagnostic Products segment. All net sales to Centeon and Alpha were
generated from the Therapeutic Products segment. At December 26, 1999, the
Company's accounts receivable from Bayer and Alpha were approximately $17.6
million and $186,000, respectively.

13. EMPLOYEE SAVINGS PLAN

     The Company maintains a defined contribution 401(k) savings plan for all
eligible employees. Under the plan, the Company matches a specified percentage
of each participating employee's compensation. Effective January 1, 1999,
employees immediately become vested in the Company's contributions as they are
made. The Company's contributions were $114,000, $205,000 and $518,000 in 1997,
1998 and 1999, respectively.

14. SEGMENT AND GEOGRAPHIC INFORMATION

     Effective December 27, 1998, the Company adopted SFAS No. 131 for financial
reporting of its operating segments. SFAS No. 131 defines operating segments to
be those components of a business about which separate financial information is
available that is regularly evaluated by management in making operating
decisions and in assessing performance. SFAS No. 131 further requires that the
segment information presented be consistent with the basis and manner in which
management internally disaggregates financial information for the purposes of
assisting in making internal operating decisions. The Company's business
activities are conducted and managed primarily through two business segments,
the Therapeutic Products segment and the Diagnostic Products segment. These
segments were determined based primarily on the differing nature of the ultimate
end use of the Company's products, the differing production and other
value-added processes performed by the Company with respect to the products and,
to a lesser extent, the differing customer bases to which each reportable
segment sells its products. The remainder of the Company's operations that do
not otherwise fall into one of these two segments, as well as general,
unallocated corporate overhead expenses, are reported in the category entitled
"Corporate and Other". Prior period amounts have been restated to conform to the
requirements of this statement.

     The activities of the Therapeutic Products segment include the collection
and sale of human antibodies that are used as the active ingredients in
therapeutic products for the treatment and management of diseases such as Rh
incompatibility in newborns, hepatitis and rabies. The activities of the
Therapeutic Products segment also include the general operations of the
Company's central testing laboratory in Atlanta, Georgia. The activities of the
Diagnostic Products segment include the Company's protein fractionation facility
in Kankakee, Illinois, the monoclonal antibody production facilities in the U.K.
and the sales and marketing efforts related to certain human-sourced, polyclonal
antibodies. The antibodies provided by the Diagnostic Products segment are used
in diagnostic products such as blood typing reagents and diagnostic test kits.
The blood proteins manufactured by the Company's fractionation facility in
Kankakee, Illinois are generally sold

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

for use as cell culture media in biotechnology products or in diagnostic
reagents. The Company's donor centers are generally classified and managed as
assets and operations of the Therapeutic Products segment which provide, on an
incremental basis and at cost, antibodies for sale by the Diagnostic Products
segment. Such sales are recorded as direct sales of the Diagnostic Products
segment; accordingly, no intersegment sales are recorded.

     The Company's senior management utilizes multiple forms of analysis of
operating and financial data to assess segment performance and to make operating
decisions with respect to the segments. While segment financial statements are
prepared on the same basis as the Company's consolidated financial statements,
the primary focus of senior management is on gross profit, and, to a lesser
extent, segment operating income, defined as earnings before income taxes,
interest, amortization, foreign currency gains and losses, special charges and
other non-operating expenses. The accounting policies of the segments are the
same as those described in the summary of significant accounting policies (Note
2).

     The Company's segment information as of and for the years ended December
28, 1997, December 27, 1998 and December 26, 1999 is as follows (in thousands):

GEOGRAPHIC INFORMATION

     The Company markets its products and services to numerous countries
worldwide and has operations in the United States and the United Kingdom. Other
than in the United States and Germany, the Company does not conduct business in
any one country in which its sales in that country are material to the Company
as a whole. However, the majority of the Company's remaining foreign sales is to
western Europe. Net sales are attributed to regions based on the country to
which the Company ships its products, which can differ from their ultimate
destination. The composition of the Company's net sales to unaffiliated
customers between those in the United States, Germany and other foreign
locations for each fiscal year is set forth below (in thousands):

15. RESTATED QUARTERLY RESULTS OF OPERATIONS (UNAUDITED)

     As part of its assessment of its compliance with the Securities and
Exchange Commission's Staff Accounting Bulletin No. 101, "Revenue Recognition in
Financial Statements" issued in December 1999, the Company determined that its
revenue recognition policy as it related to the timing of recording sales under
an existing arrangement with a single customer of its Serologicals Proteins
subsidiary should be amended. Consequently, the Company reversed net sales of
$607,000 and $792,000 that had been previously recognized

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

during the fiscal quarters ended June 27, 1999 and September 26, 1999,
respectively. The Company recognized $1,032,000 of such sales in the fourth
quarter of 1999 and expects to record the remaining sales upon shipment of the
product in fiscal 2000. The Company also had significant changes in its
operations during 1999, which it believes caused certain errors to occur in
recording certain sales, cost of sales and other expenses in the first three
fiscal quarters of 1999 that were previously undetected. These errors resulted
in an overstatement of previously reported net sales of $564,000 and an
understatement of previously reported cost of sales and other expenses of
$908,000 during the first three quarters of 1999. As a result, the Company is
restating its results of operations for the first three fiscal quarters of 1999.
The above items related only to the Company's 1999 unaudited quarterly operating
results and had no impact on previously reported cash flows. The Company's
unaudited quarterly results of operations as previously reported and as restated
are as follows:
