ITEM 1. BUSINESS
 
    The Company is a leading worldwide provider of specialty human antibodiezs
and related 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 products 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 and supplies antibodies
for the manufacture of intravenous immune globulin (IVIG), a product containing
a broad spectrum of antibodies used in the treatment of a wide variety of
medical indications. As of March 20, 1998, the Company conducted its operations
through a national network of 59 donor centers and through laboratories located
in the United States and the United Kingdom. The Company also operates two
monoclonal manufacturing facilities in Scotland. The majority of the Company's
16 specialty donor centers are strategically located on or near medical
campuses, enhancing the Company's ability to source specialty antibodies from
medical community referrals.
 
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.
 
    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. The other sector of the
market, the commercial sector, is focused primarily on supplying source plasma,
specialty and non-specialty antibodies found in source plasma and other
specialty biologic components to healthcare companies for use as the active
ingredients in therapeutic and diagnostic products. According to the Marketing
Research Bureau, Inc., an independent market research company, the worldwide
market for finished products made from plasma-based products grew from
approximately $1.5 billion in 1984 to approximately $5.4 billion in 1996.
 
    The specialty segment of the commercial sector includes products consisting
of specialty antibodies and cells. Specialty antibodies are typically used to
manufacture products for treating persons exposed to, or at risk of, contracting
a specific disease and to make diagnostic products used to screen patients for
prior exposure to a specific disease or to determine blood type. Specialty
antibodies range from those used to treat medical indications such as tetanus,
respiratory syncytial virus (RSV) and cytomegalovirus (CMV), which the Company
believes generally sell for approximately $90 to $110 per liter, to high-end
products such as anti-D, an antibody used to treat Rh incompatibility in
newborns, anti-hepatitis and blood typing reagents, which the Company believes
generally sell for approximately $400 to $800 per liter. By comparison, the
average industry gross price of source plasma, from which IVIG and other
products are derived, is approximately $75 to $85 per liter. The Company's
pricing for its specialty antibodies averaged approximately $493 per liter in
1997, an increase of approximately 10% from 1996.
 
    The Company believes that there are a number of factors increasing the
demand for 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. 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
 
                                       4
<PAGE>
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 current treatment regimens.
 
    The Company believes that there are a number of factors that are limiting
the supply of commercially available antibodies. The supply of antibodies has
been adversely affected by the more rigorous screening procedures required by
regulatory authorities, in particular the FDA, industry trade organizations and
manufacturers of these products. These procedures, which include a more
extensive investigation into a donor's background and new tests to detect the
presence of disease-causing organisms, have disqualified numerous potential
donors and discouraged other donors who may be reluctant to undergo the
screening procedures. Second, 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
hyperimmunization. Furthermore, the length of time required to be granted
regulatory licenses for antibody collection sites (donor centers), testing
facilities and biological products is significant.
 
    In addition to the demand and supply factors discussed above, the industry
continues to experience a number of trends. One such trend is the movement by
healthcare companies towards obtaining antibodies and other biologic products
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. 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. As a result of these
trends, the industry has been undergoing a consolidation for several years.
 
OPERATIONS
 
    As of March 20, 1998, the Company conducted its operations through a
national network of 59 donor centers and through laboratories located in the
United States and the United Kingdom. The Company also operates two monoclonal
production facilities in Scotland. The majority of the Company's 16 specialty
donor centers are strategically located on or near medical campuses, enhancing
the Company's ability to source specialty antibodies from medical community
referrals.
 
    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 communication network with medical
professionals and healthcare organizations nationwide to assist in identifying
these donors. 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 therapeutic and diagnostic products and
maintains an ongoing communications program to recruit donors and make medical
professionals aware of its capabilities and needs.
 
    DONOR SCREENING AND PRODUCT COLLECTION.  Each donor candidate undergoes a
process that includes an explanation of the program, extensive physiological and
biological screening, a physical examination and the collection of test samples.
In addition, donors of specialty antibodies undergo qualification profiling.
Once a candidate is accepted as a donor, the Company may collect antibodies from
the donor at its donor centers through a FDA approved collection procedure known
as plasmapheresis, which lasts between 40 and 60 minutes and is very similar to
donating blood. However, as red blood cells are returned to the donor by means
of centrifugation, individuals may donate as frequently as twice per week. Each
donation is
 
                                       5
<PAGE>
quarantined at the donor center while test samples are sent to the Company's, or
its customers', clinical laboratory for FDA mandated viral marker screening
tests (hepatitis, HIV, etc.) and characterization (i.e., special analytical
tests to identify and measure the quality and concentration of the targeted
antibodies). Beginning July 1, 1997, new industry specifications require that
each donor's ("Applicant Donor") donation be quarantined until such time that a
second donation is received from the Applicant Donor and appropriate tests
results are obtained on both donations. If a second donation is not received
from the Applicant Donor within six months, the previous donation must be
destroyed. Once these two donations and their tests are complete and acceptable,
the Applicant Donor becomes a "qualified donor" and all future donations are
generally available for immediate shipment once the mandated tests have been
completed.
 
    PRODUCT CHARACTERIZATION.  The Company characterizes its specialty
antibodies to ensure that concentrations meet 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 as long as ten years. A significant portion of
the Company's donors of rare specialty antibodies have entered into contracts
with the Company pursuant to which they have agreed to donate antibodies
exclusively to the Company for a three-year period.
 
    HYPERIMMUNIZATION.  In response to customer demands to produce higher
quality products, all of the Company's 16 specialty donor centers are actively
involved in the hyperimmunization of their specialty antibody donors. The
Company is also approved to hyperimmunize donors for anti-D and ship such
product at eight of its non-specialty donor centers. Hyperimmunization 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 hyperimmunization for several of the Company's products are
commercially available, the Company believes it has a key 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 hyperimmunized
donors and used to develop monoclonal products for diagnostic use. The Company
intends to continue its strategy of adding hyperimmunization capabilities at its
historically non-specialty donor centers.
 
    MONOCLONAL ANTIBODY PRODUCTION.  In addition to collecting antibodies from
its donors, the Company, through its Bioscot, Ltd. ("Bioscot") subsidiary,
produces monoclonal, or cloned, antibodies from approximately 45 cell lines,
which generated nearly $14 million in net sales in 1997. The Company's
FDA-licensed monoclonal manufacturing facilities in Edinburgh and Livingston,
Scotland produce monoclonal antibodies from cells derived through the Company's
donor network or acquired from other laboratories. Once suitable donors are
identified by personnel at the Company's donor centers, activated white cells
are collected and delivered to its research and development laboratory. The
white blood cells are cultivated into a proliferating cell line and then moved
to the Company's monoclonal manufacturing facility where the cell line is
further developed until it can be used for commercial production. Through this
monoclonal manufacturing capability, the Company has been able to introduce new,
second generation, human
 
                                       6
<PAGE>
monoclonal products and also begin to sell more profitable finished products
outside the United States, such as its value-added line of OEM and branded blood
typing reagents for use by healthcare workers in countries outside the United
States.
 
PRODUCTS
 
    Through its value-added services, the Company provides the antibodies that
serve as the active ingredients in certain therapeutic and diagnostic products
manufactured by major healthcare companies. The Company's customers generally
further process the Company's products. The finished materials are then packaged
and distributed as intramuscular and intravenous therapeutic or diagnostic
products. The Company also sells certain antibodies for blood typing reagents
directly to end-users. In 1997, the Company derived approximately 81% of its net
sales from its therapeutic product line, a substantial majority of which related
to IVIG and anti-D antibodies, and approximately 19% of its net sales from its
diagnostic product line, the majority of which relates to blood typing reagents.
 
    End products produced by the Company's customers for which it supplies
antibodies include the following:
 
SPECIALTY THERAPEUTIC PRODUCTS
 
    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 may affect up to 100,000 Americans.
 
    The Company believes that demand for anti-D antibodies used in the treatment
of RhHDN have generally followed the birth rate of developed countries.
Continuing supply shortages of anti-D antibodies have resulted in industry-wide
price increases over the past several years. Moreover, due to the relatively
recent use of anti-D antibodies for the treatment of ITP, the Company believes
that worldwide demand for anti-D antibodies has increased more rapidly over the
past several years.
 
    ANTI-RABIES IMMUNE GLOBULIN ("RIG").  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. RIG 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, RIG is administered in
conjunction with a rabies vaccine, which is used to provide the patient with an
additional active immunity to the rabies virus.
 
    ANTI-HEPATITIS IMMUNE GLOBULIN.  The traditional use for anti-hepatitis
immune globulin ("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-RESPIRATORY SYNCYTIAL VIRUS IMMUNE GLOBULIN ("ANTI-RSV").  Anti-RSV is
used in the prevention of serious lower respiratory tract infections caused by
RSV. RSV is the leading cause of pneumonia and bronchiolitis (an infection of
the small airways of the lung) in infants, causing approximately 90,000
hospitalizations and 4,500 fatalities in the United States annually. Certain
populations, such as premature infants and infants with lung problems, are at
increased risk for developing severe RSV disease. The Company commenced
collecting antibodies for anti-RSV during 1997.
 
                                       7
<PAGE>
    ANTI-CYTOMEGALOVIRUS IMMUNE GLOBULIN (ANTI-CMV).  Anti-CMV is used in the
treatment of patients with compromised immune systems and thus most at risk for
severe CMV infection, such as AIDS patients, transplant recipients and cancer
patients undergoing chemotherapy. CMV is a herpes virus affecting a significant
portion of the population but usually going unnoticed in people with healthy
immune systems. The Company does not anticipate significant growth in providing
antibodies for this product beyond 1997.
 
NON-SPECIALTY THERAPEUTIC PRODUCTS
 
    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.
 
SPECIALTY DIAGNOSTIC PRODUCTS
 
    ANTIBODIES FOR BLOOD TYPING REAGENTS.  Blood typing reagents are used by
blood banks and hospital transfusion services worldwide to assure compatibility
between the recipient and the donor's blood type. Traditionally, blood typing
reagents were made primarily from human sourced, or polyclonal, antibodies. Over
the past several years, monoclonal antibodies have been developed to provide
certain high quality antibodies on a consistent basis, and many of these are now
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. While the majority of these antibodies
are in monoclonal form, the Company continues to collect human sourced
polyclonal antibodies and expanded its ability to do so as a result of the
September 1997 acquisition of Bio-Lab, Inc. and Med-Lab, Inc. (collectively,
"Bio-Lab").
 
    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 extensive in-house experience in the laboratory
disciplines of immunohematology, immunology, serology and clinical chemistry to
characterize human specimens to meet manufacturers' requirements.
 
PRODUCT AND SERVICE DEVELOPMENT
 
PRODUCTS
 
    The Company is engaged in a number of near-term development projects
designed to enhance its existing product lines. These projects include the
development of more efficacious donor immunization protocols to increase yields
and the development of more efficient techniques for the manufacture of both
polyclonal and 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.
 
    On a longer-term basis, the Company is evaluating several alternatives for
the development of a therapeutic monoclonal anti-D product. Monoclonal
production techniques eliminate the need for fractionation of the product and
may give the Company the ability to market more value-added finished therapeutic
products directly to end-users. During 1997, the Company effectively ceased
research and development activities with the Scottish National Blood Transfusion
Service for the joint development and clinical trial of a therapeutic monoclonal
anti-D product. This decision was based in part on concerns with the commercial
viability of the Company's project in particular and in part on the market
potential for any
 
                                       8
<PAGE>
such product. However, the Company continues to monitor the therapeutic
monoclonal anti-D market and is pursuing strategic alternatives, including
future collaborations or partnerships with existing research projects, to bring
such a product to market.
 
SERVICES
 
    In the near-term, the Company intends to utilize its expertise in regulatory
and protocol compliance, multi-site management, quality assurance, data
management, donor recruitment and acquisitions to exploit what it believes are
significant internal and external growth opportunities in the management and
conduct of clinical trials for the pharmaceutical and biotech industries. Based
on various industry data available, the Company believes that the global market
for clinical site services is potentially $5-6 billion, yet is highly fragmented
and will begin consolidating. The Company intends to enter this industry through
the acquisition of clinical trial sites and, eventually, through the
introduction of these services at its existing donor centers. There are no
assurances, however, that the Company will successfully complete acquisitions of
clinical trial sites, or successfully integrate any such acquisition into its
existing operations.
 
    On a longer-term basis, the Company has identified and investigated several
potential niche service offerings including, but not limited to, the collection
of or therapy involving therapeutic apheresis or plasma exchange and autologous
blood and cell collections. The Company believes it can take advantage of its
existing regulatory and donor center infrastructure to provide a lower-cost,
value-added setting for these services.
 
    The Company believes a number of these and several other specialty service
areas also represent external growth opportunities where it can further leverage
its infrastructure and expertise. These include, but are not limited to, the
consolidation of existing therapeutic apheresis, cell salvage and other
transfusion related services which the Company believes currently are all highly
fragmented and emerging segments of the healthcare services industry.
 
MARKETING AND CUSTOMERS
 
    The Company markets its antibody products to over 200 customers worldwide,
including several major healthcare companies. However, in 1995, 1996 and 1997,
sales to the Company's top ten customers accounted for approximately 82%, 87%
and 84%, respectively, of net sales. One of the Company's customers, Bayer
Corporation ("Bayer"), accounted for approximately 50%, 56% and 47% of the
Company's net sales in 1995, 1996 and 1997, respectively, while another
customer, Centeon, accounted for approximately 13%, 15% and 11% of net sales in
1995, 1996 and 1997, respectively. In connection with the acquisition of Nations
Biologics, Inc., and its affiliates (the "Nations Group") in 1997, the Company
commenced selling IVIG antibodies to Alpha Therapeutic Corporation, which
accounted for approximately 12% of net sales during 1997. During 1995, 1996 and
1997, no other single customer of the Company accounted for greater than 10% of
net sales. In 1995, 1996 and 1997, the Company's domestic sales represented
approximately 68%, 68% and 74%, respectively, of net sales.
 
THERAPEUTIC MARKETING AND CUSTOMERS
 
    The majority of the Company's therapeutic products are sold through its own
sales force and, in certain markets, through independent brokers, to major
biological product manufacturers. The majority of the Company's specialty
antibodies for therapeutic use are sold pursuant to annual purchase orders, and
prices are negotiated annually. The Company is a party to three five-year supply
contracts with Bayer for the sale of IVIG antibodies produced at the majority of
its non-specialty donor centers. Such contracts, which in 1997 accounted for
approximately 31% of the Company's net sales, expire in 1999 and provide for the
sale of specified amounts on an escalating basis over the terms of the
contracts. After 1999, the contracts are subject to one-year renewals. At its
option, Bayer may also purchase any production in excess of the stipulated
minimums. Effective July 1, 1997, the Company negotiated an increased, uniform
price
 
                                       9
<PAGE>
under the contracts, its first since December 1994, which is henceforth subject
to annual negotiations. Targeted amounts to be purchased by Bayer are subject to
up to 20% reductions; however, the Company is eligible to sell such production
to other customers. The contracts are subject to the maintenance of certain
quality criteria, certain termination events and production incentives. In
addition, either Bayer or the Company can reduce, by up to 10%, the quantity
supplied upon notification. Early termination of the agreements by Bayer could
have a material adverse effect on the Company. The Company has been notified by
Bayer of its intent to reduce certain purchase commitments under the contracts.
As the Company has already received purchase orders from other customers for the
majority of this material, it does not believe that such reductions will have a
material adverse effect on it or its operations.
 
    In connection with the Company's acquisition of the Nations Group in 1997,
the Company acquired several supply contracts with Alpha Therapeutics
Corporation for the sale of IVIG antibodies collected at certain of the donor
centers operated by the Nations Group. The contracts vary in term, price and
volume levels, but are generally similar to the Company's other supply contracts
for IVIG antibodies.
 
DIAGNOSTIC MARKETING AND CUSTOMERS
 
    The Company's monoclonal and polyclonal antibodies are sold to more than 50
manufacturers or suppliers of blood typing reagents and independent brokers. 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. Monoclonal antibodies used to manufacture
blood typing reagents represent a relatively new technology and 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.
 
    In 1997, the Company's clinical diagnostic antibodies were sold to more than
60 customers in 10 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 is a "Preferred Provider" and sells a significant portion of its
clinical diagnostic antibodies pursuant to a supply contract with Abbott
Laboratories, Inc. ("Abbott") which was renegotiated during 1996 and expires in
December 1999. The agreement with Abbott is subject to termination on 30 days
notice upon the occurrence of certain events related to an uncured breach of
such agreement or immediately upon the acquisition of control of the Company by
a competitor of Abbott.
 
ACQUISITIONS
 
    The commercial sector of the blood products and services industry is
undergoing a consolidation driven largely by the rising cost and complexity
related to increased regulatory compliance requirements. A significant component
of the Company's business strategy has and continues to include acquisitions
which enable the Company to participate in the consolidation of the industry and
to add complementary products and services which will expand the Company's
current product and service portfolio.
 
    A significant factor in the Company's recent growth has been the acquisition
of donor centers. The Company intends to continue to implement its strategy to
acquire additional donor center locations throughout the United States in order
to expand its antibody-sourcing network. The Company believes that acquiring
additional donor center operations will allow it to leverage its general and
administrative costs over a greater volume of production, thereby creating
economies of scale. In addition, the Company believes that these acquisitions
will enable the Company to leverage its core competencies and infrastructure to
allow the acquired businesses to provide, on an incremental basis, additional
higher-margin specialty products and services that the Company offers. The
Company also intends to pursue acquisitions
 
                                       10
<PAGE>
of businesses that provide services and products that are complementary to its
existing businesses. 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.
 
    In accordance with this strategy, in March 1997 the Company acquired the
Nations Group for approximately $10.2 million in cash and a $4.0 million
convertible note plus additional consideration based primarily on the future
performance of the acquired business. The Nations Group operated 16 donor
centers specializing primarily in the collection of non-specialty IVIG
antibodies but also maintained a significant donor base of anti-CMV donors.
 
    In September 1997, the Company acquired Bio-Lab for approximately $5.95
million in cash and a $2.55 million convertible note. The acquisition of Bio-Lab
added two specialty donor centers which increased the Company's donor base for
specialty antibodies.
 
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 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
 
    The Company is engaged in the business of providing antibodies, which is a
competitive and rapidly 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. The Company competes for donors, primarily on a local level, 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. Additionally, 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. There can be no assurance that competition will not
adversely affect the Company.
 
    The Company believes it takes on average 10-12 months to obtain FDA approval
for a non-specialty donor center, and takes on average 16-18 months to obtain
the necessary regulatory approvals in order to begin shipping product from a
specialty donor center which hyperimmunizes its donors. In addition to these
regulatory 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. Due to
 
                                       11
<PAGE>
increasing quality requirements and more stringent testing procedures, there is
an increasing need for economies of scale, which generally only larger companies
can provide.
 
GOVERNMENT AND INDUSTRY REGULATION
 
    GENERAL.  The Company's activities are subject to significant regulation by
numerous governmental authorities in the U.S. 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. The Company believes it is
in substantial compliance with all relevant laws and regulations.
 
    The Company is subject to extensive FDA regulation.  All of the Company's 59
donor centers and the Company's monoclonal manufacturing facilities hold FDA
establishment licenses and the Company's 16 specialty donor centers have
numerous product licenses, which are granted by the FDA for products shipped in
interstate commerce. The Company is also licensed to hyperimmunize donors for
anti-D and to ship such product at eight of its non-specialty donor centers. The
Company is seeking FDA license amendments to commence shipping anti-D currently
being collected from hyperimmunized donors at an additional five non-specialty
donor centers.
 
    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 undergo FDA review prior
to implementation. The Company's FDA-licensed collection, testing and
manufacturing operations in the United States and abroad are required to adhere
to FDA current Good Manufacturing Practices (cGMP) and are routinely inspected
by the FDA. 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 company is not in compliance with
applicable laws and regulations, 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 withdrawn in certain circumstances. Failure to comply with regulatory
requirements or a significant adverse regulatory action could have a material
adverse effect on the Company. There has been an increasing level of regulatory
scrutiny in the industry by the FDA resulting in more detailed and frequent
inspections, and 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. 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 clinical testing
laboratory under the Clinical Laboratories Improvement Act of 1988. The
Company's clinical testing laboratory in Atlanta (Clarkston), 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 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
 
                                       12
<PAGE>
facilities prior to the shipment of products to such countries. Changes in
existing federal, state or foreign laws or 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.
 
    One specific concern currently facing the industry is Creutzfeld-Jakob
disease ("CJD"), 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 and 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, effective
April 1997 and with respect to certain products, one of the Company's customers
ceased accepting antibodies collected from donors over the age of 59.
 
    Another new standard voluntarily accepted by the industry, which was adopted
in July 1997, 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 donors' plasma is excluded from further manufacture
until 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
customers are considering implementing a testing method using Polymerase Chain
Reaction ("PCR") technology. PCR testing is a method used to detect the presence
of genetic material of problem viruses before antibodies against those viruses
can be formed.
 
    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.
 
    PRODUCT APPROVALS.  Before new specialty antibody collection activities can
be initiated at any donor center, separate approvals for each type of specialty
antibody to be collected must be obtained from the FDA. There can be no
assurance that difficulties or delays will not arise in connection with
applications for approval to conduct expanded antibody collection activities.
 
    Federal, state and foreign laws and regulations regarding the manufacture
and sale of blood 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.

<PAGE>
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 increasingly 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. Moreover, the Company's profitability
may be directly affected by the availability of third party reimbursement for
any finished monoclonal product it seeks to sell.
 
EMPLOYEES
 
    As of March 20, 1998, the Company employed approximately 1,100 persons,
approximately 1,020 of whom were located in the United States and approximately
80 of whom were located in the United Kingdom. None of the Company's employees
is covered by a collective bargaining agreement. 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 antibody-based products
involve a risk of product and professional liability claims. The Company has
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 $5.0 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 59 donor centers are located in 20 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 which 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 clinical testing laboratory and international headquarters are
located in Atlanta (Clarkston), GA; 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.
 
    During 1997, the Company completed the expansion of its monoclonal antibody
production facility to meet current and anticipated future demand for its
diagnostic products. During 1997, the Company also completed a significant
expansion of its laboratory testing facility and international headquarters in
Clarkston, Georgia.

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 28, 1997.

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER
  MATTERS.
 
    The Company's common stock was initially offered to the public on June 15,
1995 at a price of $7.67 per share and trades on the Nasdaq Stock Market
("Nasdaq") under the symbol "SERO."
 
    The Company declared a three-for-two split of its common stock effective
February 28, 1997 for shareholders of record on February 10, 1997. All price and
share amounts herein are adjusted to reflect the effect of such split.
 
    On September 9, 1997, the Company sold 950,000 shares of its common stock,
at a price of $19.50 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 will be used for general corporate purposes,
including strategic acquisitions and investments. Pursuant to the same
transaction, one of the Company's shareholders sold 250,000 shares of common
stock; the Company did not receive any of the proceeds from this sale. A
registration statement relating to the resale by the purchasers of the shares of
common stock sold by the Company was declared effective by the Securities and
Exchange Commission on September 3, 1997.
 
    On March 20, 1998, the closing price of the common stock was $27.19 per
share. As of March 20, 1998, there were 132 holders of record and approximately
1,750 beneficial holders of the Company's common stock.
 
    The Company has not paid any cash dividends on its common stock to date. The
payment of cash dividends, if any, in the future is within the discretion of the
Board of Directors and will depend on the Company's earnings, its capital
requirements and financial condition. It is the present intention of the Board
of Directors to retain all earnings, if any, for use in the Company's business
operations and, accordingly, the Board of Directors does not expect to declare
or pay any cash dividends in the foreseeable future. In addition, under the
Company's Second Amended and Restated Credit Agreement dated as of October 16,
1997, with NationsBank, N.A., there are limitations on the Company's ability to
pay cash dividends.
 
    The following table sets forth the high and low sale prices for the
Company's common stock for the periods indicated as reported by Nasdaq.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
  OF OPERATIONS
 
OVERVIEW
 
    The Company is a leading worldwide provider of specialty human antibodies
and related services to major healthcare companies. The Company also collects
antibodies for the manufacture of intravenous immune globulin (IVIG), a product
containing a broad spectrum of antibodies used in the treatment of a wide
variety of medical indications. As of March 20, 1998, the Company operated 59
donor centers, 16 of which specialize in specialty antibody collections and 43
of which primarily collect IVIG antibodies from which a number of products are
produced. Through the Company's Bioscot, Ltd. ("Bioscot") subsidiary, it also
operates two FDA-licensed monoclonal antibody manufacturing facilities in
Scotland.
 
    A significant component of the Company's external growth strategy has been
the acquisition of donor centers. The Company continued to implement this
strategy in 1997 with the March acquisition of the Nations Group for
approximately $10.2 million in cash and a $4.0 million convertible note plus
additional consideration contingent on the future performance of the Nations
Group. The acquisition of the Nations Group added 16 non-specialty donor centers
and a significant new customer, Alpha Therapeutics Corporation. In September
1997, the Company acquired Bio-Lab for approximately $5.95 million in cash and a
$2.55 million convertible note. The Bio-Lab acquisition added two new specialty
donor centers and increased the Company's donor base for anti-D and diagnostic
polyclonal antibodies. Each of these acquisitions was accounted for using the
purchase method of accounting.
 
    In September 1997, the Company sold 950,000 shares of its common stock, at a
price of $19.50 per share, in a private placement transaction. The net proceeds
to the Company from the sale of the shares were approximately $17.5 million and
will be used for general corporate purposes, including strategic acquisitions
and investments. Pursuant to the same transaction, one of the Company's
shareholders sold 250,000 shares of common stock; the Company did not receive
any of the proceeds from the sale of these shares.
 
    In February 1997, the Company declared a 3-for-2 split of its common stock
effected in the form of a 50% stock dividend paid on February 28, 1997 to
holders of record as of February 10, 1997. All share and per share amounts
herein have been retroactively adjusted to reflect such split.
 
    Increasing regulatory scrutiny continues to be a significant factor shaping
the industry, resulting in more detailed and frequent 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 a new approach to
inspections of donor centers and manufacturing facilities, including the
Company's customers', entitled "Team Biologics". Under this new approach,
substantially all such inspections will be performed by highly trained field
investigators who will focus more extensively on the FDA's current good
manufacturing practices (GMP) and the Quality Assurance guidelines adopted by
the FDA in 1995. This approach was first applied to the plasma fractionation
industry and subsequently to other biologic product areas, including 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, certain manufacturers are
currently experiencing a longer than anticipated FDA approval process of new
facilities in order to expand production. While such actions have, in some
cases, temporarily delayed or reduced the Company's sales to certain of its
customers, to date, they have not had a material adverse effect on the Company
or its operations as demand for the end products remains strong. However, there
can be no assurance that such actions will not have an adverse effect on the
Company or its operations in the future. See Item 1., "Business -- Government
and Industry Regulation."
 
                                       19
<PAGE>
    On occasion, the Company has received notifications and deficiency notices
from the FDA of possible deficiencies in the Company's compliance with FDA
regulations or its own internal standard operating procedures. To date, the
Company believes that it has adequately addressed or corrected such
deficiencies.
 
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 operating data of the Company as a

</TABLE>
 
    YEARS ENDED DECEMBER 29, 1996 AND DECEMBER 28, 1997
 
    Net sales increased 48.7%, or $32.0 million, from $65.6 in 1996 to $97.5
million in 1997. Of the increase, approximately $15.4 million was the result of
acquisitions completed during 1997, while approximately $3.8 million related to
the full-year effect of acquisitions completed throughout the prior year. The
remainder of the increase, or approximately $12.8 million, resulted primarily
from increased sales of the Company's specialty antibodies, in particular,
anti-D, monoclonal antibodies and clinical diagnostic antibodies, and to a
lesser extent, the increased sales of non-specialty IVIG antibodies.
Contributing to the increased sales in 1997 was approximately $1.6 million of
antibodies for respiratory syncytial virus, or RSV, a new product which
commenced shipping in 1997, and approximately $1.1 million of incremental anti-
HBs produced at the Company's non-specialty donor centers that were approved
during 1997 to commence shipping such product.
 
    During 1997, therapeutic and diagnostic antibodies represented approximately
81% and 19% of net sales, respectively, versus 78% and 22%, respectively, in the
prior year.
 
    Gross profit increased 32.3%, or $8.7 million, from $26.8 million in 1996 to
$35.5 million during the current year. The majority of the increase, or
approximately $6.4 million, was attributable to additional sales of, and higher
margins on, specialty antibodies, in particular anti-D and monoclonal
antibodies, and to a lesser extent, additional sales of non-specialty IVIG
antibodies. The remainder of the increase, or approximately $2.2 million,
related to acquisitions completed during 1997 and 1996. Contributing to the
increase in gross profit was approximately $1.1 million relating to the
Company's introduction of RSV antibodies and to the first shipments of anti-HBs
from the Company's non-specialty donor centers. Gross profit as a percentage of
net sales ("gross margin") decreased from 40.9% in 1996 to 36.4% in 1997,
primarily attributable to an increase in net sales of relatively lower-margin
IVIG antibodies as a percentage of total net sales from approximately 34% in
1996 to 42% in 1997, offset in part by higher margins on anti-D antibodies.
 
    Selling, general and administrative expenses increased 30.1%, or $2.8
million, from $9.4 million in 1996 to $12.2 million in the current year. The
increase was primarily attributable to a larger sales, financial and, in
particular, information systems and regulatory infrastructure needed to support
the Company's acquisitions and internal growth. However, selling, general and
administrative expenses, as a percentage of net sales, decreased from 14.3% to
12.5% as the Company continued to effectively leverage its corporate
infrastructure.
 
                                       20
<PAGE>
    Product development expenses decreased $242,000, or 10.8%, from $2.2 million
in 1996 to $2.0 million in 1997, due primarily to a reduction in expenditures
relating to the development of a therapeutic monoclonal anti-D product. As a
result, product development expenses as a percentage of net sales decreased from
3.4% in 1996 to 2.1% in 1997.
 
    Other expense increased $867,000, or 47.0%, from approximately $1.8 million
in 1996 to $2.7 million in 1997, substantially all due to the amortization of
goodwill and other intangible assets resulting from acquisitions completed
during 1997 and 1996.
 
    Interest expense, net, decreased $752,000, from net interest expense of
$220,000 in 1996 to net interest income of $532,000 in the current year. The
change was primarily a result of higher cash balances during the year and the
September 1997 receipt of approximately $17.5 million in net proceeds from a
private placement of the Company's common stock, offset in part by the
additional interest expense attributable to convertible notes issued in
acquisitions.
 
    YEARS ENDED DECEMBER 31, 1995 AND DECEMBER 29, 1996
 
    Net sales increased by 25.8%, or $13.4 million, from $52.1 million in 1995
to $65.6 million in 1996. Approximately $6.9 million of the increase was the
result of acquisitions completed in 1996 and the fourth quarter of 1995. The
remainder of the increase, or approximately $6.5 million, resulted from
additional net sales of the Company's specialty antibodies, the majority of
which was anti-D and, to a lesser extent, additional net sales of the Company's
non-specialty and monoclonal antibodies. Net sales of the Company's therapeutic
and diagnostic products increased 35.3% and 1.3%, respectively, from the prior
year.
 
    Gross profit increased 30.2%, or $6.2 million, from $20.6 million in 1995 to
$26.8 million in 1996. Of the increase, approximately $4.0 million was
attributable to additional sales of, and higher margins on, the Company's
specialty antibodies, while approximately $1.8 million was attributable to
acquisitions completed in 1996 and the fourth quarter of 1995. Gross margins
increased from 39.5% to 40.9%, reflecting the higher margins on the Company's
specialty antibodies (primarily a result of a favorable product mix), offset in
part by increased sales of the Company's non-specialty IVIG antibodies, which
generally generate lower gross margins. Gross margins from the Company's
specialty antibodies increased from 48.8% in 1995 to 53.3% in 1996.
 
    Selling, general and administrative expenses increased 14.3%, or $1.2
million from $8.2 million in 1995 to $9.4 million in 1996. Recurring expenses
increased $1.5 million, or 19.4%, from $7.9 million to $9.4 million in 1996. The
increase is primarily attributable to increased professional and administrative
expenses associated with being a public company, the hiring of an additional
Vice President during the first quarter of 1996, an expanded sales and marketing
staff at the Company's Bioscot subsidiary and the general corporate
infrastructure needed to support the Company's acquisitions and growth.
Non-recurring expenses in 1995 consisted of a $346,500 charge for compensation
expense related to the acceleration of vesting of an officer's stock options in
connection with the Company's initial public offering ("IPO"). As a percentage
of sales, selling, general and administrative expenses decreased from 15.8% to
14.3%.
 
    Product development expenses increased 13.6%, or $268,000, from $2.0 million
in 1995 to $2.2 million in 1996, due primarily to increased spending to develop
additional monoclonal antibodies for blood typing reagents.
 
    Other expense increased 39.0%, or $519,000, from $1.3 million in 1995 to
$1.8 million in 1996, due primarily to the amortization of intangible assets
resulting from acquisitions completed in 1996 and the fourth quarter of 1995
and, to a lesser extent, non-capitalizable expenses incurred in the expansion of
the Company's monoclonal production capacity.
 
    Interest expense, net decreased 89.6%, or $1.9 million, from $2.1 million in
1995 to $220,000 in 1996, due primarily to the retirement of approximately $25
million of debt in June 1995 with proceeds from the
 
                                       21
<PAGE>
IPO, the retirement of approximately $7.9 million of debt in June 1996 with the
proceeds of a secondary offering of common stock and the subsequent investment
of the remaining proceeds.
 
    In 1996, the Company recorded an extraordinary loss (net of income taxes) of
$14,206 related to the write off of previously capitalized debt issuance costs
upon the early extinguishment of certain indebtedness.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    The following table sets forth certain indicators of financial condition and
liquidity of the Company as of the following year-ends:

Cash and cash equivalents...................................  $   2,887  $  21,232  $   31,812
Working capital.............................................      6,174     20,705      37,555
Long-term debt and capital lease obligations................      7,023      3,714       6,798
Stockholders' equity........................................     36,593     67,883     103,415
Total debt to equity ratio..................................       19.2%       5.5%        6.6%
</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 Revolver (as defined below). Management believes
the Corporation'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 will be available for use in its acquisition
strategy. However, the Company anticipates that future acquisition and growth
opportunities may require supplementary funding, including the issuance of
equity or debt securities.
 
    During 1997, the Company's sales to one customer, Bayer Corporation,
accounted for approximately 47% of its total sales. Sales of specialty
antibodies to Bayer Corporation are generally made pursuant to annual purchase
orders while the sale of non-specialty antibodies are generally made pursuant to
three, five-year supply contracts. The revenues and cash flows generated from
these supply contracts are significant; early termination or material revisions
in the supply requirements or other terms of these contracts could adversely
affect the Company's ability to meet its financial obligations in the short
term.
 
    Net cash provided by operating activities in 1997 was $12.3 million as
compared to $11.7 million in the prior year, an increase of $603,000. This
increase was primarily attributable to increased net income of $3.8 million and
$1.5 million of additional non-cash depreciation and amortization expense,
offset by an increased investment in working capital of approximately $4.7
million over the prior year. The increase in working capital was in large part
due to a larger increase in accounts receivable of $4.0 million, primarily
resulting from increased sales volume, as days sales outstanding remained
relatively unchanged from the prior year. The Company was also required to fund
a $1.1 million larger investment in inventory which resulted primarily from the
introduction of anti-RSV and the increased production of anti-CMV, which
generally have a longer testing and customer approval process before shipping,
and from temporary delays in shipping non-specialty IVIG antibodies due to the
transitioning of several donor centers, previously under supply contracts, to
other customers.
 
    Net cash used in investing activities in 1997 was $20.9 million as compared
to $11.1 in the previous year. Investing activities in 1996 primarily consisted
of the acquisitions of Southeastern Biologics, Inc. and its affiliates, Am-Rho
Laboratories, Inc. and Simi Biologics, Inc. for aggregate cash consideration of
approximately $6.9 million (net of cash acquired) in addition to approximately
$4.2 million in capital expenditures. Investing activities in 1997 consisted
primarily of the acquisitions of the Nations Group and Bio-Lab for aggregate
consideration of approximately $15.7 million (net of cash acquired) as well as
capital expenditures of approximately $4.4 million.
 
                                       22
<PAGE>
    Capital expenditures relate primarily to the Company's facilities, related
equipment and information systems. Capital expenditures made in 1997 were
primarily funded through cash flow from operations. The significant expenditures
of 1997 included the expansion of the Company's laboratory testing facility and
international headquarters in Clarkston, Georgia, the completion of the
expansion of the Company's monoclonal production facility and the upgrading of
the Company's information system.
 
    During 1998, the Company has plans for capital expenditures of approximately
$9.0 million, $4.2 million of which relates to the continued expansion and
upgrading of the Company's information systems.
 
    Net cash provided by financing activities in 1997 was approximately $19.2
million as compared to $17.7 million in the prior year. Financing activities in
1996 primarily consisted of the Company's June 1996 public stock offering which
raised approximately $22.0 million in net proceeds. Financing activities in 1997
consisted primarily of net proceeds of approximately $17.5 million from a
private placement sale of 950,000 shares of the Company's common stock in
September 1997.
 
    Total long-term debt and capital lease obligations were $6.8 million at
December 28, 1997, an increase of $3.1 million from December 29, 1996. This
increase was primarily due to the issuance of approximately $6.6 million of
convertible promissory notes as partial acquisition consideration, offset by the
conversion of a $3.5 million note into the Company's common stock.
 
    During 1997, the Company amended its revolving credit facility (the
"Revolver"), increasing the total borrowing capacity from $20 million to $35
million, of which $30 million may be used for acquisitions. The Company
anticipates using the proceeds from the Revolver primarily to fund acquisitions.
There were no amounts outstanding under the Revolver at December 29, 1997.
 
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 fail or create erroneous results after December 31, 1999, or
before, to the extent a system references future dates. This Year 2000 issue is
believed to affect the majority of all companies and organizations worldwide,
including the Company.
 
    In response to increasing regulatory scrutiny and to improve customer
service and increase its operating performance and efficiency, the Company has
recently undertaken a number of significant information system initiatives.
These initiatives include the installation of a new laboratory system during
1997 and the development of a donor center operating system (DCOS) expected to
be completed in the next 18 months. An ancillary benefit of these initiatives is
that the resulting systems are Year 2000 compliant. The Company is in the
process of evaluating all other owned and leased products and will upgrade those
products that are intended for continued use beyond the year 1999. Furthermore,
the Company is analyzing the Year 2000 issue as it relates to its customers and
suppliers and what, if any, impact that could have on the Company. Analysis and
evaluation activities were begun in 1997 and are currently in varying stages of
completion.
 
    The Company does not expect that the cost of its Year 2000 compliance
program will be material to its business, results of operations or financial
condition. The Company believes that it will be able to achieve compliance by
the end of 1999 and does not currently anticipate any material disruption of its
operations as the result of any failure by the Company to be in compliance.
Although the impact on the Company caused by the failure of the Company's
significant suppliers or customers to achieve Year 2000 compliance in a timely
or effective manner is uncertain, the Company's business and results of
operations could be materially adversely affected by such failure.

FOREIGN OPERATIONS
 
    The Company's foreign operations are primarily conducted through Bioscot. In
1995, 1996 and 1997, foreign operations accounted for 17.8%, 15.4% and 14.1% of
net sales and 25.2%, 17.0%, and 15.4% of income from operations, respectively.
Export sales from the United States were $11.6 million, $14.0 million and $16.8
million during 1995, 1996 and 1997, respectively.
 
    The functional currency of Bioscot is the British pound sterling.
Fluctuations in foreign exchange rates can impact operating results, including
total revenues and expenses, when translations of the subsidiary financial
statements are made in accordance with SFAS No. 52, "Foreign Currency
Translation." It has not been the Company's practice to hedge its assets and
liabilities in the U.K. or its intercompany transactions due to the inherent
risks associated with foreign currency hedging transactions and the timing of
payment between the Company and Bioscot. In 1995, 1996 and 1997, the Company
recorded foreign currency transaction gains (losses) of approximately $29,000,
$46,000, and ($10,000), respectively.
 
OUTLOOK
 
    The Company's strategy is to continue to expand its specialty and
non-specialty business and to take advantage of emerging opportunities relating
to the provision of other biologic products and services. The key elements of
this strategy include (i) expanding its core business by increasing its donor
base and broadening the range of antibodies it sources and the services it
provides; (ii) pursuing selective acquisitions to capitalize on opportunities in
a consolidating industry; (iii) expanding customer relationships by providing
additional services, allowing the Company to become more deeply involved in its
customers' product development, regulatory compliance and quality assurance
programs; (iv) seeking to increase the quality of antibodies and production
efficiencies; and (v) utilizing its existing donor center network and expertise
in biologic product development, manufacturing techniques and regulatory
compliance to capitalize on emerging opportunities in other specialty biologic
based products and services. However, there can be no assurance that the Company
will be successful in achieving any or all of the elements of its strategy.
 
    External growth through acquisitions is a significant component of the
Company's strategic plan. The Company's strategy includes acquisitions of
selected specialty and non-specialty donor centers, as well as businesses that
provide services and products that are complementary to its existing business.
The Company believes that these acquisitions will enable it to leverage its core
competencies and its general and administrative infrastructure, thereby creating
economies of scale. However, there can be no assurance that the Company will be
able to complete suitable acquisitions in the future or successfully integrate
such acquisitions into the Company's business to achieve economies of scale.
 
    The Company intends to utilize its expertise in regulatory and protocol
compliance, multi-site management, quality assurance, data management, donor
recruitment and acquisitions to exploit what it believes are significant
internal and external growth opportunities in the management and conduct of
clinical trials for the pharmaceutical and biotech industries. The Company
intends to enter this industry through the acquisition of clinical trial sites
and, eventually, through the introduction of these services to its existing
donor center network. However, there can be no assurance that the Company will
be successful in implementing its strategy.
 
    The Company intends to capitalize on its existing monoclonal technology to
take advantage of the increasing preference of its customers for more consistent
and uniform antibody yields achievable through monoclonal manufacturing
techniques. During 1997, the Company completed the expansion of its monoclonal
antibody production facilities in Scotland. This expansion will enable the
Company to implement more efficient manufacturing techniques, as well as provide
additional production capacity for diagnostic monoclonal products.
 
                                       24

    The industry in which the Company operates is subject to strict regulation
and licensing by the FDA. Similar regulation exists in many of the states and
foreign countries where the Company conducts 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 February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings per
Share" ("SFAS No. 128"), which the Company adopted in its fiscal quarter and
year ending December 28, 1997. This statement established new, simplified
standards for computing and presenting earnings per share. SFAS No. 128 replaced
the traditional presentations of primary earnings per share and fully diluted
earnings per share with basic earnings per share and diluted earnings per share,
respectively. Basic earnings per share excludes the dilutive effect of stock
options, warrants, convertible indebtedness and similar instruments while
diluted earnings per share is computed similarly to fully diluted earnings per
share. All earnings per share reported herein have been restated pursuant to the
provisions of SFAS No. 128.
 
    In July 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income"
("SFAS No. 130"), which establishes standards for reporting and display of
"comprehensive income", which is the total of net income and all other non-owner
changes in stockholders' equity, and its components. The Company is in the
process of evaluating SFAS No. 130 and its impact and will adopt the standard in
the first quarter of its 1998 fiscal year.
 
    In July 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information" ("SFAS No. 131"). SFAS No. 131, which
supersedes SFAS Nos. 14, 18, 24 and 30, establishes new standards for segment
reporting, using the "management approach," in which reportable segments are
based on the same criteria on which management disaggregates a business for
making operating decisions and assessing performance. The Company is in the
process of evaluating SFAS No. 131 and its impact and will adopt the standard
for its 1998 fiscal year.

                    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 29, 1996
and December 28, 1997 and the related consolidated statements of income,
stockholders' equity and cash flows for each of the three years in the period
ended December 28, 1997. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Serologicals Corporation and
subsidiaries as of December 29, 1996 and December 28, 1997 and the results of
their operations and their cash flows for each of the three years in the period
ended December 28, 1997 in conformity with generally accepted accounting
principles.

1. ORGANIZATION AND BUSINESS OPERATIONS
 
    Serologicals Corporation (a Delaware corporation) (the "Company") is a
leading worldwide provider of specialty human antibodies and related 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 antibodies that are used as the active ingredients in therapeutic
and diagnostic pharmaceutical products.
 
    The Company, through its wholly-owned subsidiaries, operates a national
network of 59 donor centers, 16 of which specialize in the collection of
specialty antibodies and 43 of which primarily collect non-specialty plasma from
which a number of therapeutic products, primarily intravenous immune globulin
("IVIG"), are derived. The Company also operates laboratories in the United
States and Scotland and two U.S. Food and Drug Administration ("FDA") licensed
monoclonal antibody manufacturing facilities in Scotland.
 
    The industry in which the Company operates is subject to strict regulation
and licensing by the FDA. Similar regulation exists in many of the states and
foreign countries where the Company conducts business. Changes in existing
federal, state or foreign laws or regulations could have an adverse effect on
the Company's business.
 
    The industry is also characterized by sales to a relatively few major
healthcare companies. One of the Company's customers, Bayer Corporation
("Bayer"), accounted for approximately 47% of the Company's net sales in 1997
(Note 11). The Company has three, five-year supply contracts with Bayer for the
sale of non-specialty IVIG antibodies which accounted for approximately 31% of
the Company's net sales in 1997; however, there can be no assurance that the
contracts will not be terminated or that Bayer will not materially change its
supply requirements pursuant to the agreements.
 
    Export sales from the United States represented approximately 17% of net
sales in 1997 (Note 13). Concern over the safety of blood products has led to
movements in a number of European and other countries to restrict the
importation of blood and blood derivatives, including antibodies, 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
imposition of new restrictions will not have a material adverse effect on the
Company.
 
    The Company's business is dependent upon its ability to attract and retain
qualified antibody donors. A significant 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 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 Bioscot, Ltd. ("Bioscot") subsidiary, which accounted for
approximately 14% of the Company's net sales in 1997 (Note 13), 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 antibody inventories is net
realizable value and for supplies is replacement cost.
 
    Inventories at December 29, 1996 and December 28, 1997 consisted of the
following (in thousands):

</TABLE>
 
PROPERTY AND EQUIPMENT
 
    Fixed assets are stated at cost and are depreciated using straight-line and
accelerated methods over their estimated useful lives for financial reporting
purposes. For income tax purposes, the Company uses only 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. Expenditures for
maintenance and repairs are charged to expense as incurred.

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.

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 but are accumulated and reported as a separate component
of stockholders' equity. Gains and losses, which result from foreign currency
transactions, are included in the accompanying consolidated statements of income
and were not material to the Company in any of the years presented.
 
DEBT DISCOUNTS
 
    The Company recorded an original issue discount ("OID") of approximately
$2.0 million in connection with the issuance of a subordinated note and a
related warrant (Note 7) in 1994. In 1995, the subordinated note was repaid in
full with proceeds from the Company's initial public offering ("IPO") (Note 3)
and the remaining OID was expensed. The write-off of approximately $1.4 million
(net of income taxes) was recorded as an extraordinary loss.
 
GOODWILL
 
    The excess of cost over the fair market value of the net assets acquired
("goodwill") is being amortized to income on a straight-line basis over a period
of 25 years. The goodwill relates primarily to the acquisition of donor centers.
The Company periodically reviews the carrying values assigned to goodwill based
upon expectations of future cash flows and operating income generated by the
underlying assets in determining whether goodwill is recoverable.
 
FDA LICENSES
 
    In connection with the Company's acquisitions (Note 4), it acquired the
licenses of the FDA-approved donor centers. The estimated fair value of the FDA
licenses is capitalized and amortized to income on a straight-line basis over a
period of 25 years.
 
NONCOMPETE AGREEMENTS
 
    In connection with certain of the Company's acquisitions (Note 4), it
entered into noncompete agreements with the sellers. Such agreements are
recorded at their estimated fair market value and are being amortized to income
on a straight-line basis over the terms of the respective agreements, which
range from three to five years.
 
DEBT ISSUANCE COSTS
 
    The Company incurred debt issuance costs in connection with certain of its
long-term debt (Note 7). These costs were capitalized and amortized to interest
expense over the term of the debt.
 
    During 1995 and 1996, the Company recorded extraordinary losses (net of
income taxes) of approximately $454,000 and $14,000, respectively, related to
the write off of previously capitalized debt issuance costs upon early
extinguishment of certain indebtedness.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
EARNINGS PER SHARE
 
    As of December 28, 1997, the Company adopted SFAS No. 128, "Earnings per
Share" ("SFAS No. 128"), which requires a dual presentation of basic earnings
per share and diluted earnings per share on the face of the consolidated
statements of income. All prior period earnings per share data have been
restated to comply with the provisions of SFAS No. 128. SFAS No. 128 establishes
new, simplified standards for computing earnings per share and replaces the
traditional presentations of primary earnings per share and fully diluted
earnings per share with basic earnings per share and diluted earnings per share,
respectively. Basic earnings per share excludes the dilutive effect of stock
options, warrants, convertible indebtedness and similar instruments while
diluted earnings per share is computed similarly to fully diluted earnings per
share. The impact to the Company of adopting SFAS No. 128 was an increase to
basic earnings per share over the previously reported primary earnings per share
of $0.01 and $0.03 for 1995 and 1996, respectively. Diluted earnings per share
is the same as the Company's previously reported primary earnings per share.
 
    The following table sets forth the calculation of basic and diluted earnings
per share ("EPS") (in thousands, except per share amounts):

    The EPS calculation for 1995 and 1996 excludes 480,549 and 375,000 shares,
respectively, for convertible notes as their inclusion would have been
antidilutive.
 
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"). Effective in 1996, the Company adopted the disclosure
requirements of SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS
No. 123"). 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 6).
 
RECENT ACCOUNTING PRONOUNCEMENTS
 
    In July 1997, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 130, "Reporting Comprehensive Income" ("SFAS No. 130"), which establishes
standards for reporting and display of

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
"comprehensive income", which is the total of net income and all other non-owner
changes in stockholders' equity, and its components. The Company is in the
process of evaluating SFAS No. 130 and its impact and will adopt the standard in
the first quarter of its 1998 fiscal year.
 
    In July 1997, the FASB issued SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information" ("SFAS No. 131"). SFAS No. 131, which
supersedes SFAS Nos. 14, 18, 24 and 30, establishes new standards for segment
reporting, using the "management approach," in which reportable segments are
based on the same criteria on which management disaggregates a business for
making operating decisions and assessing performance. The Company is in the
process of evaluating SFAS No. 131 and its impact and will adopt the standard
for its 1998 fiscal year.
 
3. SALES OF COMMON STOCK
 
    On June 14, 1995, the Company completed an IPO of 3.6 million shares of its
common stock at a price of $7.67 per share, which resulted in proceeds of $27.6
million (before underwriting discounts and other offering expenses). The net
proceeds of approximately $24.6 million were used to reduce long-term debt. This
early retirement of debt resulted in an extraordinary loss of approximately $1.8
million (net of income taxes) due to early retirement costs associated with a
subordinated note and the write off of debt issuance costs (Notes 2 and 7).
 
    In June 1996, the Company completed an offering (the "Secondary Offering")
of 3.15 million shares of its common stock at a price of $17.33 per share. Of
the 3.15 million shares, the Company sold 1.35 million shares, which resulted in
net proceeds of approximately $22.0 million, including proceeds from options
which were exercised and the resulting shares sold pursuant to the Secondary
Offering. The net proceeds were used to retire approximately $7.9 million of
debt, with the remainder, or approximately $14.1 million, available to the
Company for general corporate purposes. The Company recognized an extraordinary
loss of approximately $14,000 (net of income taxes) related to the early
retirement of debt.
 
    In September 1997, the Company sold 950,000 shares of its common stock, at a
price of $19.50 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 are available for general corporate purposes,
including strategic acquisitions and investments. Pursuant to the same
transaction, one of the Company's shareholders sold 250,000 shares of common
stock; the Company did not receive any of the proceeds from this sale.

4. ACQUISITIONS
 
    In February 1996, the Company acquired the assets of Am Rho Laboratories,
Inc. ("Am-Rho"), which operated two specialty donor centers, for approximately
$1.7 million. The purchase price consisted of $1.1 million in cash at closing,
the assumption of certain liabilities and forgiveness of a $500,000 note
receivable from the parent of Am-Rho.
 
    In March 1996, the Company acquired the stock of Southeastern Biologics,
Inc. and Plasma Management, Inc. and substantially all of the assets of Concho
Biologics, Inc. (collectively, "Southeastern") in a single transaction for
approximately $4.75 million. The acquisition of Southeastern, which operated six
non-specialty donor centers, included a provision for contingent consideration
based on the performance of the acquired businesses over the 12 months
subsequent to closing. The purchase price consisted of approximately $3.6
million in cash and the assumption of approximately $1.15 million of
indebtedness at closing. During 1997, the Company paid approximately $960,000 of
additional consideration related to the post-acquisition performance of the
donor centers acquired, which was recorded as additional goodwill.
 
    In December 1996, the Company acquired substantially all of the assets of
Simi Biological Resources, Inc. ("Simi"), which operated three non-specialty
donor centers. The purchase price consisted of $1.6 million in cash at closing,
before recording certain acquisition expenses. The acquisition agreement
included a provision for up to $300,000 of contingent consideration upon the
passing of certain regulatory testing. The contingencies were resolved in 1997,
resulting in $300,000 additional consideration paid or accrued as of December
28, 1997, which was recorded as additional goodwill.
 
    In March 1997, the Company acquired Nations Biologics, Inc. and its
affiliates (the "Nations Group") for approximately $14.2 million (the "Nations
Acquisition"), before recording certain transaction costs and subject to
adjustment based primarily on the post-acquisition performance of the businesses
acquired over the 14-month period subsequent to closing. The Company expects to
determine the amount of additional consideration, if any, during 1998. The
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
maturing on March 7, 2002 (the "Nations Note"). The Company financed the $10.2
million of cash paid at closing with cash on hand. The Nations Group operated 16
donor centers which primarily specialize in the collection of non-specialty IVIG
antibodies.
 
    The following unaudited data summarize the pro forma results of operations
for the years ended December 29, 1996 and December 28, 1997 as if the Nations
Acquisition had occurred on January 1 of each year. 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 dates indicated, or what the results of

    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 certain transaction costs and subject to adjustment based on
the net assets of the companies acquired, as defined, as of the closing date.
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.
 
    Each of the 1997 acquisitions 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 estimated 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.
 
5. STOCKHOLDERS' EQUITY
 
STOCK SPLIT
 
    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. As a result of
the split, 4,707,048 additional shares of common stock were issued. All share
and per share amounts herein have been restated to reflect this stock split.
Additionally, common stock and additional paid-in capital amounts have been
restated to reflect the issuance of the additional shares.

5. STOCKHOLDERS' EQUITY (CONTINUED)
CAPITAL STOCK
 
    Under the terms of the 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 WARRANT
 
    In connection with a bank credit agreement entered into in 1993, the Company
issued a warrant to a bank to purchase 221,624 shares of the Company's common
stock at an exercise price of $2.29 per share of common stock. The warrant is
currently exercisable and expires on March 9, 2003. As of December 28, 1997,
warrants to purchase 108,436 shares of common stock remained outstanding.
 
    The warrant holder had a put option to require the Company to repurchase the
warrant or any shares previously purchased by the warrant holder exercisable on
the earlier of an IPO by the Company, or on no more than three separate
occasions during the period from March 9, 1996 to March 9, 2003. The common
stock put warrant was being accreted to its highest redemption price, as defined
in the agreement, from the date of issuance to June 14, 1995. The accretion was
$45,556 in 1995. Upon the successful completion of the Company's IPO in 1995,
the put option was waived by the warrant holder and the accretion related to the
common stock put warrants was credited to additional paid-in capital.
 
    In connection with the issuance of a subordinated note in 1994, the Company
issued a warrant (the "NationsBanc Warrant") to an affiliate of a bank
("NationsBanc") to purchase 546,054 shares of the Company's common stock at a DE
MINIMIS exercise price per share. The Company assigned the NationsBanc Warrant a
value of approximately $2.0 million based on an estimated fair value of $3.67
per common share on the date of issuance. During 1995, the Company paid the
subordinated note with proceeds from the IPO and wrote off the remaining OID
(Note 2). Additionally, in September 1995, NationsBanc exercised the NationsBanc
Warrant to purchase 545,703 shares of the Company's common stock.

6. STOCK COMPENSATION PLANS
 
OFFICER STOCK OPTIONS
 
    During March 1993, the Company entered into an employment agreement with an
officer. As part of the agreement, the officer was granted two options (the
"base option" and the "market option") to purchase shares of the Company's
common stock. Under each option, the officer can purchase up to 252,000 shares
of common stock at an exercise price of $2.29 per share (the estimated fair
value on the date of grant). During December 1994, the market option was amended
in order to fix the vesting period while the option price per share remained at
$2.29. The amendment of the market option created a new measurement date
resulting in the Company recording unearned compensation and an increase in
additional paid-in capital in the amount of $346,500. In conjunction with the
amendment of the market option, the officer was granted additional options to
purchase 230,238 shares of common stock at an exercise price of $3.67, the
estimated fair market value at the date of grant. All of these options have a
term of ten years and became fully vested as of the IPO date of June 14, 1995.
As a result, in June 1995, the Company recognized the compensation expense
related to the accelerated vesting of the officer's stock options. During 1996
and 1997, options to purchase 75,000 and 40,000 shares, respectively, of common
stock at an exercise price of $2.29 per share were exercised.
 
1994 OMNIBUS INCENTIVE PLAN
 
    In November 1994, the Company approved the Omnibus Incentive Plan (the
"Omnibus Plan"). The Omnibus Plan provides for the issuance of stock options to
key employees and directors. During 1996, the Company amended the Omnibus Plan
increasing the number of shares reserved under the plan from 648,000 to
2,250,000. Options granted under the Omnibus Plan can have varying terms as
determined by the Board of Directors. Options granted through 1997 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 are
eligible for accelerated vesting upon the Company's achievement of certain
predetermined performance objectives which are approved by the Compensation
Committee of the Company's Board of Directors. As of December 28, 1997, the
Company had 464,023 shares available for grant under the Omnibus Plan.
 
1995 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN
 
    During August 1995, the Company approved the Non-Employee Director Stock
Option Plan (the "Director Plan"). The Director Plan provides for the issuance
of stock options to non-employee directors. During 1996, the Company amended the
Director Plan, increasing the number of shares reserved under the plan from
240,000 to 540,000. Pursuant to the Director Plan, each person who becomes a
non-employee director of the Company is automatically granted an option to
purchase 48,000 shares of the Company's common stock on the date of adoption or
on the 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 3,000 shares of common stock on an annual basis to
each non-employee director of the Company after the initial 48,000 option grant
has vested in full. Options granted in 1996 and 1997 under the Director Plan
typically vest over a four-year period, while options granted during 1995 were
fully vested upon issuance. As of

6. STOCK COMPENSATION PLANS (CONTINUED)
December 28, 1997, 111,000 shares had vested under the Director Plan. As of
December 28, 1997, the Company had 330,000 shares available for grant under the
Director Plan.
 
EMPLOYMENT STOCK OPTIONS
 
    During 1997, the Company entered into employment agreements with four
individuals not previously employed by the Company. As an inducement to enter
into these agreements, the individuals were granted options to purchase an
aggregate of 408,750 shares of the Company's common stock (the "Employment
Options"). 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 at the rate of 25% per annum and
contains other terms and conditions similar to options issued under the Omnibus
Plan. During 1997, options to purchase 78,750 shares of common stock were
forfeited concurrent with the resignation of one of the individuals. As of
December 28, 1997, options to purchase 330,000 shares were outstanding, none of
which had vested.

EMPLOYEE STOCK PURCHASE PLAN
 
    In May 1996, the stockholders of the Company approved the 1996 Employee
Stock Purchase Plan (the "Purchase Plan"). Pursuant to the terms of the Purchase
Plan, eligible employees are able to purchase 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. There are currently 369,838 shares reserved for issuance under
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 fair market
value on the date of the respective grants. Had compensation expense for the
Company's stock-based compensation plans been determined in accordance with the
provisions of

6. STOCK COMPENSATION PLANS (CONTINUED)
SFAS No. 123, the Company's net income and earnings per share would have been
reduced to the pro forma amounts indicated below (in thousands, except per share
amounts):
 
<TABLE>
<CAPTION>
                                                                                        1995       1996       1997

Net income
    As reported.....................................................................  $   2,643  $   8,236  $  12,002
    Pro forma.......................................................................      2,189      6,362      9,357

    As reported.....................................................................  $    0.23  $    0.58  $    0.76
    Pro forma.......................................................................       0.19       0.45       0.60
</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 are 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:

                                                                 ---------  ---------  ---------
<S>                                                              <C>        <C>        <C>
Expected life (years)..........................................        4.0        4.0        4.4
Dividend yield.................................................          0%         0%         0%
Expected volatility............................................         55%        55%        50%
Risk-free interest rate........................................       6.76%      5.51%      6.22%
</TABLE>
 
    Under these assumptions for the Omnibus Plan, the Director Plan and the
Employment Options, the weighted average fair value of options granted in 1995,
1996 and 1997 was $2.73, $5.90 and $9.77, respectively. No other options were
granted in 1995, 1996 or 1997.

    In connection with an acquisition in 1994, the Company issued the sellers a
$3.5 million convertible subordinated note. During 1997, the holders of this
note exercised their conversion rights thereunder, resulting in the issuance of
375,000 shares of the Company's common stock.
 
    During 1997, the Company amended its revolving credit facility with
NationsBank, N.A. (the "Revolver"). The amendment increased the borrowing
capacity to $35 million, of which $30 million may be used for acquisitions. The
Revolver bears interest at a variable rate and is payable in full on October 16,
2000. The Company may elect either a floating rate or Eurodollar interest rate
option applicable to borrowings under the Revolver. The floating rate and
Eurodollar interest rate options are based on the base rate, as defined, plus a
floating rate margin that fluctuates on the basis of the Company's leverage
ratio. The initial floating rate margin under the Revolver is 0% for the
floating rate option and 1.5% for the Eurodollar rate option. The Company is
required to pay a fee of .375% 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 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.
 
    In connection with the acquisition of the Nations Group, the Company issued
one of the sellers the Nations Note, which matures on March 7, 2002. The Nations
Note bears interest at a rate of 4.5% per annum through the earlier of the date
of repayment, conversion or March 7, 2000. On or after March 7, 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 Nations Note, subject to certain
restrictions as to minimum amounts and frequency. The Nations Note is
convertible at the option of the holder at a conversion price of $18.76 per
share, the fair market value of the Company's common stock at the date of
issuance. The Company has the right to call the Nations Note at any time
commencing March 7, 2000, or earlier if certain events occur.

7. LONG-TERM DEBT AND CAPITAL LEASE OBLIGATIONS (CONTINUED)
    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 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 of 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 $20.97 per share, the fair market value of the Company's
stock at the date of issuance.
 
    Future maturities of long-term debt and capital lease obligations at

SUPPLY CONTRACTS
 
    The Company is party to several agreements for the sale of non-specialty
antibodies to two customers at specified prices which are typically renegotiated
annually. The contracts 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.
 
LITIGATION
 
    The Company is involved in certain litigation arising in the ordinary course
of business. In the opinion of management, the ultimate resolution of these
matters will not have a material adverse effect on the Company's financial
position or results of operations.
 
9. 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 relatively short maturity of these instruments.
 
NOTES PAYABLE
 
    The Company estimates that the fair value of notes payable approximates
carrying value based upon its effective 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 29, 1996 and
December 28, 1997. 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
December 28, 1997 and current estimates of fair value may differ significantly
from the amounts presented herein.

of October 16, 1997 between SEROLOGICALS CORPORATION, formerly known as 
Serologicals Holdings, Inc. (the "Company") and NATIONSBANK, N.A., 
successor to NationsBank, N.A. (South) and prior to that known as 
NationsBank of Georgia, National Association (the "Lender").

     Pursuant to the terms of that certain Amended and Restated Credit 
Agreement dated as of July 20, 1995 (the "Existing Credit Agreement") by 
and between the Company and the Lender, the Lender made available to the 
Company a revolving credit facility in the amount of $20,000,000 and a 
swingline facility in the amount of $2,000,000.

     The Company and the Lender desire to amend and restate the terms of the 
Credit Agreement to increase the amount of such revolving credit 
facility, to change the financial covenants, and for other purposes.

     Accordingly, the parties hereto agree to amend and restate the terms of 
the Existing Credit Agreement as follows:

                   Definitions and Accounting Matters

1.1.  Certain Defined Terms

     As used herein, the following terms shall have the following 
meanings (all terms defined in this Section or in other provisions of 
this Agreement in the singular to have the same meanings when used in 
the plural and vice versa):

     "ABRA" shall mean the American Blood Resources Association.

     "Account Receivable" shall mean, as of any date of determination 
thereof, the unpaid portion of the obligation of a customer of an

any unpaid credits, rebates, offsets or commissions.

     "Accession Agreement" shall mean an Accession Agreement to Credit 
Documents substantially in the form of Exhibit C executed by any Loan 
Party in favor of the Lender.

or a series of transactions, of (a) all or substantially all of the 
assets of such Seller or all or substantially all of a line or lines of 
business conducted by such Seller or a division of such Seller or (b) a 
controlling equity interest in such Seller, whether by purchase of such 
equity interest or upon the exercise of an option or warrant for, or 
conversion of securities into, such equity interest.

maintained against "Eurocurrency liabilities" as specified in 
Regulation D of the Board of Governors of the Federal Reserve System (or 
against any other category of liabilities which includes deposits by 
reference to which the interest rate on LIBOR Loans is determined or any 
category of extensions of credit or other assets which includes loans by 
an office of the Lender outside of the United States of America to

having ordinary voting power for the election of directors or other 
governing body of a corporation or 10% or more of the partnership or 
other ownership interests of any other Person (other than as a limited

which the applicable financial statements are required to be delivered

1.2.  Accounting Terms and Determinations

     (a)  Except as otherwise expressly provided herein, all accounting 
terms used herein shall be interpreted, all calculations for purposes of 
determining compliance with the terms of this Agreement shall be made, 
and all financial statements and certificates and reports as to 
financial matters required to be delivered to the Lender hereunder shall

financial covenants contained herein shall continue to be determined in 
accordance with GAAP as in effect prior to such change; provided, 
however, that the Company and the Lender will thereafter negotiate in 
good faith to revise such covenants to the extent necessary to conform 
such covenants to GAAP as then in effect.

     (b)  To enable the ready and consistent determination of compliance 
with the covenants set forth in Article 7. and Article 8., the Company 
will not, without the prior written consent of the Lender, which consent 
shall not be unreasonably withheld, change its fiscal year.

mean such document, instrument or agreement, or replacement or 
predecessor thereto, as amended, modified or supplemented from time to 
time and in effect at any given time.  Wherever from the context it 
appears appropriate, each term stated in either the singular or plural 
shall include the singular and plural, and pronouns stated in the 
masculine, feminine or neuter gender shall include the masculine, the 
feminine and the neuter.  

     (d)  If, during any four fiscal quarter period for which the 
Borrower's compliance with the financial covenants in Sections 8.1. 
through 8.3. is to be determined, any Loan Party shall have acquired all 
or substantially all of the assets of another Person, all or 
substantially all of a line or lines of business conducted by another 
Person, a division of another Person or a controlling equity interest in 
another Person (such assets, lines of business, division or, in the case 
of an equity interest, such Person, being a "Target"), then the 
financial performance of the Target after its acquisition by such Loan 
Party shall be annualized during such four fiscal quarter period when 
determining compliance with such Sections.

<PAGE>


that the failure of the Lender to make any such recordation or 
endorsement shall not affect the obligations of the Company to make a 
payment when due of any amount owing under such Note.  Any such 
recordations or endorsements made by the Lender on its books or the 
Notes shall be conclusive and binding on the Company absent manifest 
error.

2.10.  Optional Prepayments
     The Company shall have the right to prepay Loans in whole or in 
part at any time or from time to time, without premium or penalty, 
except that in connection with any prepayment of LIBOR Loans on a day 
other than the last day of the Interest Period applicable thereto (other 
than in the case of a prepayment of all outstanding Loans and the 
termination of the Revolving Commitment and the Swingline Commitment), 
the Company as a condition to such prepayment shall pay all amounts 
contemplated by Section 3.9. in connection with such prepayment.

2.11.  Mandatory Prepayments of Loans and Reduction of Commitments

     (a)  Loans in Excess of Commitments.  If at any time the aggregate 
amount of Revolving Loans outstanding shall exceed the Revolving 
Commitment in effect at such time, the Company shall, within one 
Business Day, prepay the Revolving Loans in such amounts as shall be 
necessary so that the aggregate principal amount of the Revolving Loans 
outstanding shall not exceed the Revolving Commitment.  If at any time 
the aggregate amount of Swingline Loans outstanding shall exceed the 
Swingline Commitment in effect at such time, the Company shall, within 
one Business Day, prepay the Swingline Loans in such amounts as shall be 
necessary so that the aggregate principal amount of the Swingline Loans 
outstanding shall not exceed the Swingline Commitment.  If at any time 
the aggregate amount of all Loans outstanding shall exceed the Revolving 
Commitment in effect at such time, the Company shall, within one 
Business Day, prepay the Loans in such amounts as shall be necessary so 
that the aggregate principal amount of all Loans outstanding shall not 
exceed the Revolving Commitment.  

     (b)  Dispositions.  At the written request of the Lender, upon the 
receipt by the Company and the other Loan Parties of Net Proceeds in 
respect of all Dispositions after the date of this Agreement in an 
aggregate amount in excess of $10,000,000, the Revolving Commitment 
shall be automatically and permanently reduced by the amount by which 
such Net Proceeds exceeds $10,000,000 and the Company shall prepay the 
Loans in the amount, if any, required under the immediately preceding 
Subsection (a).

     (c)  Sweep of Operating Account.  At 5:00 p.m. of each Business 
Day, the Company shall repay a principal amount of Swingline Loans by an 
amount equal to the positive balance, if any, of available funds on 
deposit in the Operating Account as determined by the Lender at such 
time.  The Company hereby authorizes the Lender to deduct such amount 
from the Operating Account without notice to the Company, and to apply 
such amount in repayment of the then outstanding principal balance of 
Swingline Loans.  Neither the provisions of Section 2.7. nor 3.3. shall 
apply to repayments made pursuant to this subsection.

2.12.       Use of Proceeds



<PAGE>


The Company may use the proceeds of Revolving Loans solely (a) for its 
own general corporate purposes; (b) to fund loans by the Company to its 
Subsidiaries; (c) to provide financing for Acquisitions and (d) for 
general corporate purposes of such Subsidiaries; provided, however, no 
more than $30,000,000 in the aggregate of Revolving Loans at any one 
time outstanding may be used to finance Acquisitions, refinancing of 
Indebtedness for money borrowed and repurchasing capital stock of the 
Company.  The Company may only use the proceeds of Swingline Loans to 
cover payment of drafts drawn against the Operating Account as 
contemplated by Section 2.2.(b).

                  3.  PAYMENTS; COMPUTATIONS; TAXES; ETC.

3.1. Payments

     (a)  Except to the extent otherwise provided herein, all payments 
of principal, interest and other amounts to be made by the Company under 
this Agreement and the Notes and, except to the extent otherwise 
provided therein, all payments to be made by the Company under any other 
Credit Document, shall be made in Dollars, in immediately available 
funds, without deduction, set-off or counterclaim, to the Lender at its 
Applicable Lending Office, not later than 12:00 noon Atlanta, Georgia 
time on the date on which such payment shall become due (each such 
payment made after such time on such due date to be deemed to have been 
made on the next succeeding Business Day).

     (b)  The Company shall, at the time of making each payment under 
this Agreement or any Note, specify to the Lender the Loans or other 
Obligations to which such payment is to be applied (and in the event 
that it fails to so specify, or if an Event of Default has occurred and 
is continuing, the Lender may apply such payment to the Loans in such 
manner as it  may determine to be appropriate).

     (c)  If the due date of any payment under this Agreement or a Note 
would otherwise fall on a day which is not a Business Day, such date 
shall be extended to the next succeeding Business Day and interest shall 
be payable for any principal so extended for the period of such 
extension.

3.2.  Computations

     Interest on Loans and commitment fees shall be computed on the 
basis of a year of 360 days comprised of twelve thirty-day months for 
the actual days elapsed (including the first day but excluding the last 
day) occurring in the period for which such amounts are payable.

3.3.  Certain Notices

     Notwithstanding anything contained in Section 10.2. to the 
contrary, notices by the Company to the Lender of borrowings of 
Revolving Loans (which shall be in the form of Exhibit J, each a "Notice 
of Borrowing"), of optional terminations or reductions of the Revolving 
Commitment or the Swingline Commitment, optional prepayments of Loans, 
Notices of Conversion and Notices of Continuations shall be irrevocable 
and shall be effective only if received by the Lender in writing not 
later than 12:00 noon Atlanta, Georgia time on the number of Business 
Days prior to the date of the relevant optional termination, reduction,

</TABLE>

Subject to Section 2.4., each such notice of optional termination or 
reduction of the Revolving Commitment or the Swingline Commitment shall 
specify the amount of the Revolving Commitment or the Swingline 
Commitment, as applicable, to be terminated or reduced.  Each Notice of 
Borrowing or Conversion shall specify the Type of Loans to be borrowed 
or Converted and the amount of each Loan to be borrowed or Converted and 
the date thereof (which shall be a Business Day).

3.4.  Taxes

     (a)  Any and all payments by the Company hereunder shall be paid 
(except to the extent required by law) free and clear of and without 
deduction for any and all present or future taxes, levies, imposts, 
deductions, charges or withholdings, and all liabilities with respect 
thereto, excluding franchise taxes and taxes based on net income imposed 
on the Lender by the United States (or any political subdivision 
thereof) in which the Lender has its Applicable Lending Office (all such 
nonexcluded taxes, levies, imposts, deductions, charges, withholdings 
and liabilities being hereinafter referred to as "Taxes").  If the 
Company shall be required by law to deduct any Taxes from or in 
respect of any sum payable hereunder to the Lender (i) the sum payable 
by the Company shall be increased by the amount necessary so that after 
making all required deductions (including deductions applicable to 
additional sums payable under this Section 3.4.) the Lender shall 
receive an amount equal to the sum it would have received had no such 
deductions been made, (ii) the Company shall make such deductions, and 
(iii) the Company shall pay the full amount deducted to the relevant 
taxing authority or other Governmental Authority in accordance with 
Applicable Law.

     (b)  In addition, the Company agrees to pay any present or future 
stamp or documentary taxes or any other excise or property taxes, 
charges or similar levies which arise from any payment made hereunder or 
from the execution, delivery or registration of, or otherwise with 
respect to, this Agreement or any other Credit Document (hereinafter 
referred to as "Other Taxes").

     (c)  The Company will indemnify the Lender for the full amount of 
Taxes and Other Taxes (including any Taxes or Other Taxes imposed by any 
jurisdiction on amounts payable under this Section 3.4.) paid by the 
Lender and any liability (including penalties, interest and expenses) 
arising therefrom or with respect thereto, whether or not such Taxes or 
Other Taxes were correctly or legally asserted.  Such indemnification 



<PAGE>


shall be made within five Business Days after the date of receipt of a 
written demand therefor from the Lender.

     (d)  Within 30 days after the date of any payment of Taxes or Other 
Taxes withheld by the Company in respect of any payment to the Lender, 
the Company will furnish to the Lender, at its address referred to in 
Section 10.2., the original or a certified copy of a receipt evidencing 
payment thereof.

     (e)  If the Lender claims any additional amounts payable pursuant 
to this Section, the Lender shall use reasonable efforts (consistent 
with legal and regulatory restrictions) to file any certificate or 
document reasonably requested by the Company if the making of such a 
filing would avoid the need for or reduce the amount of any such 
additional amounts which may thereafter accrue and would not, in the 
sole determination of  the Lender, be otherwise disadvantageous to the 
Lender.

3.5.  Additional Costs

     (a)  Events Entitling the Lender to Receive Compensation.  The 
Company shall pay directly to the Lender from time to time such amounts 
as the Lender may determine in good faith to be necessary to compensate 
it for any costs which it determines are attributable to its making or 
maintaining any Loans or its obligation to make any Loans hereunder, or 
any reduction in any amount receivable by the Lender hereunder in 
respect of any of such Loans or such obligation (such increases in costs 
and reductions in amounts receivable being herein called "Additional 
Costs") resulting from any Regulatory Change which:

     (i)  changes the basis of taxation of any amounts payable to the 
Lender under this Agreement or any Note or any of such Loans (other than 
taxes imposed on or measured by the overall net income of the Lender or 
of its Applicable Lending Office for any of such Loans by the 
jurisdiction in which the Lender has its Applicable Lending Office);

     (ii)  imposes or modifies any reserve, special deposit or similar 
requirements relating to any extensions of credit or other assets of, or 
any deposits with or other liabilities of, the Lender, or any commitment 
of the Lender (including the Revolving Commitment or the Swingline 
Commitment), but only to the extent the Lender determines in good faith 
that such Additional Cost is not reflected in the Base Rate; or

     (iii)  imposes any other condition affecting the interests of  the 
Lender under this Agreement or any Note (or any of such extensions of 
credit or liabilities), the Revolving Commitment or the Swingline 
Commitment.

     (b)  Determination of Amount of Compensation.  Without limiting the 
effect of the foregoing provisions of this Section 3.5. (but without 
duplication), the Company shall pay directly to the Lender from time to 
time on request such amounts as the Lender may determine to be necessary 
to compensate the Lender (or, without duplication, the bank holding 
company of which  the Lender is a subsidiary) for any increased costs 
which it determines in good faith are attributable to the maintenance by 
the Lender (or any Applicable Lending Office or such bank holding 
company) of capital in respect of the Revolving Commitment or the 



<PAGE>


Swingline Commitment or Loans pursuant to any law or regulation or any 
interpretation, directive or request (whether or not having the force of law) 
of any court or governmental or monetary authority (i) following any 
Regulatory Change or (ii) implementing any risk-based capital guideline or 
requirement (whether or not having the force of law and whether or not the 
failure to comply therewith would be unlawful) hereafter issued by any 
government or governmental or supervisory authority implementing at the 
national level the Basle Accord (including, without limitation, the Final 
Risk-Based Capital Guidelines of the Board of Governors of the Federal 
Reserve System (12 CFR Part 208, Appendix A; 12 CFR Part 225, Appendix A) and 
the Final Risk-Based Capital Guidelines of the Office of the Comptroller of 
the Currency (12 CFR Part 3, Appendix A)), such compensation to include, 
without limitation, an amount equal to any reduction of the rate of return on 
assets or equity of  the Lender (or any Applicable Lending Office or such 
bank holding company) to a level below that which  the Lender (or any 
Applicable Lending Office or such bank holding company) could have achieved 
but for such law, regulation, interpretation, directive or request.  For 
purposes of this Section 3.5.(b), "Basle Accord" shall mean the proposals for 
risk-based capital framework described by the Basle Committee on Banking 
Regulations and Supervisory Practices in its paper entitled "International 
Convergence of Capital Measurement and Capital Standards" dated July 1988, as 
amended, modified and supplemented and in effect from time to time or any 
replacement thereof.

     (c)  Notice of the Occurrence of an Event Entitling Lender to 
Compensation. The Lender shall notify the Company of any event occurring 
after the date of this Agreement that will entitle the Lender to compensation 
under Section 3.5.(a) or (b) as promptly as practicable and shall furnish to 
the Company a certificate setting forth the basis and amount of each request 
by  the Lender for compensation, together with calculations in reasonable 
detail of such amount.  Determinations and allocations by the Lender for 
purposes of this Section 3.5. of the effect of any Regulatory Change pursuant 
to Section 3.5.(a), of the effect of capital maintained pursuant to Section 
3.5.(b) on its costs or rate of return of maintaining Loans or to make Loans 
or on amounts receivable by it in respect of Loans and of the amounts 
required to compensate the Lender under this Section, shall be made in a 
manner consistent with that applied by the Lender in similar contexts and 
shall be conclusive in the absence of manifest error.

3.6.  Limitation on Types of Loans

     Anything herein to the contrary notwithstanding, if on or prior to the 
determination of LIBOR for any Interest Period the Lender determines (which 
determination shall be conclusive) that:

          (a)  quotations of interest rates for the relevant deposits 
     referred to in the definition of "LIBOR" are not being provided in  
     the relevant amounts or for the relevant maturities for purposes of 
     determining rates of interest for LIBOR Loans as provided herein; 
     or
          (b)  the relevant rates of interest referred to in the 
     definition of LIBOR in this Agreement upon the basis of which the 
     rate of interest for LIBOR Loans for such Interest Period is to be 
     determined are not likely to adequately cover the cost to the 
     Lender of making or maintaining LIBOR Loans for such Interest 
     Period;



<PAGE>


then the Lender shall give the Company notice thereof, and so long as 
such condition remains in effect, the Lender shall be under no 
obligation to make additional LIBOR Loans, to Continue LIBOR Loans or to 
Convert Base Rate Loans into LIBOR Loans, and the Company shall, on the 
last day(s) of the then-current Interest Period(s) for the outstanding 
LIBOR Loans, either prepay such Loans or Convert such Loans into Base 
Rate Loans in accordance with Section 2.6.

3.7.  Illegality

     Notwithstanding any other provision of this Agreement, if it 
becomes unlawful for the Lender to honor its obligation to make or 
maintain LIBOR Loans hereunder, then the Lender shall promptly notify 
the Company thereof and the Lender's obligation to make or Continue, or 
to Convert Base Rate Loans into, LIBOR Loans shall be suspended until 
such time as the Lender may again make and maintain LIBOR Loans.

3.8.  Treatment of Affected Loans

     If the obligation of the Lender to make, Continue or Convert Base 
Rate Loans into LIBOR Loans shall be suspended pursuant to either of the 
immediately preceding Sections, all outstanding LIBOR Loans shall be 
automatically Converted into Base Rate Loans on the last day(s) of the 
current Interest Period(s) for such LIBOR Loans (or, in the case of a 
Conversion required by Sections 3.6. or 3.7., on such earlier date as 
the Lender may specify to the Company) and, unless and until the Lender 
gives notice as provided below that the circumstances specified in 
Sections 3.6. or 3.7. which gave rise to such Conversion no longer 
exist:

(a)  to the extent that any LIBOR Loans have been so Converted, all 
payments and prepayments of principal which would otherwise be applied 
to such LIBOR Loans shall be applied instead to the Base Rate Loans; and

(b)  all Loans which would otherwise be made or Continued as LIBOR Loans 
shall be made or Continued instead as Base Rate Loans and all Base Rate 
Loans which would otherwise be Converted into LIBOR Loans shall remain 
as Base Rate Loans.

     If the Lender gives notice to the Company that the circumstances 
specified in Sections 3.6. or 3.7. which gave rise to the Conversion of 
LIBOR Loans pursuant to this Section no longer exist at a time when 
LIBOR Loans are outstanding, the Lender's Base Rate Loans shall be 
automatically Converted, at the option of the Company.

3.9.  Compensation

     The Company shall pay the Lender such amount or amounts as shall be 
sufficient to compensate the Lender for any loss, cost, or expense which 
the Lender determines in good faith is attributable to: (a) any payment, 
prepayment or Conversion of a LIBOR Loan for any reason (including, 
without limitation, the acceleration of the Loans pursuant to 
Article 9.) on a date other than the last day of the Interest Period for 
such Loan; or (b) any failure by the Company for any reason, including 
without limitation, the failure of any of the conditions precedent 
specified in Article 4. to be satisfied, to borrow a LIBOR Loan from the 



<PAGE>


Lender on the date for such borrowing specified in the relevant Notice 
of Borrowing given pursuant to Section 2.2.  Without limiting the effect 
of the preceding sentence, such compensation shall include an amount 
equal to the excess, if any, of (i) the amount of interest which 
otherwise would have accrued on the principal amount so paid, prepaid or 
Converted or not borrowed for the period (the "Remaining Period") from 
the date of such payment, prepayment, Conversion or failure to borrow to 
the last day of the then-current Interest Period for such Loan (or, in 
the case of a failure to borrow, the Interest Period for such Loan which 
would have commenced on the date specified for such borrowing) at the 
applicable rate of interest for such Loan provided for herein over 
(ii) the amount of interest which would otherwise have accrued on such 
principal amount during the Remaining Period at a rate per annum equal 
to the sum of (x) the Adjusted LIBO Rate determined as of the first day 
of the Remaining Period which would apply to a LIBOR Loan having a 
principal amount equal to or comparable to such principal amount and a 
term comparable to the Remaining Period (as determined in good faith by 
the Lender) plus (y) the Applicable Margin.

                    5.  REPRESENTATIONS AND WARRANTIES

The Company represents and warrants to the Lender that the following 
statements are, and after giving effect to the Transactions, will be, 
true and correct:

5.1.  Corporate Existence

     Each of the Company and the other Loan Parties (a) is a corporation 
duly organized and validly existing and in good standing under the laws 
of the jurisdiction of its organization; (b) has all requisite corporate 
power, and has all governmental licenses, authorizations, consents and 
approvals, necessary to own its assets and carry on its business as now 
being or as proposed to be conducted and to consummate the Transactions; 
and (c) is qualified to do business in all jurisdictions in which the 
nature of the business conducted by it makes such qualification 
necessary, except where failure so to qualify would not have a Material 
Adverse Effect, all of which such jurisdictions are set forth on 
Schedule 5.1.

5.2.  Authorization; No Conflict

     The execution, delivery and performance by the Company and the 
other Loan Parties of each of the Credit Documents and the Acquisition 
Documents to which any is a party and the consummation of the 
Transactions (a) have been duly authorized by all requisite corporate 
and, if required, stockholder action on the part of the Company and each 
such Loan Party and (b) will not (i) to the Company's actual knowledge, 
violate any provision of Applicable Law, or any order of any 
Governmental Authority, (ii) violate any provision of the certificate of 
incorporation or by-laws of the Company or any other Loan Party, (iii) 
violate, conflict with, result in a breach of or constitute (alone or 
with notice or lapse of time or both) a default or an event of default 
under any Material Contract to which the Company or any other Loan Party 
is a party or by which the Company or any other Loan Party or any of its 
property is or may be bound, or (iv) result in the creation or 
imposition of any Lien upon any property or assets of the Company or any 
other Loan Party (except pursuant to the Security Documents).

5.3.  Enforceability

     This Agreement, each other Credit Document, and each Acquisition 
Document have been duly executed and delivered by the Company and each 
of the other Loan Parties (to the extent it is a party thereto) and 
constitute the legal, valid and binding obligations of the Company and 
the other Loan Parties enforceable against the Company and the other 
Loan Parties in accordance with their respective terms, except (a) as 
the same may be limited by bankruptcy, insolvency, reorganization, 
moratorium, fraudulent conveyance or other laws affecting generally the 
enforcement of creditors' rights and by general principles of equity 
(regardless of whether considered in a proceeding in equity or at law) 
and (b) that obligations of a Loan Party resulting solely from being 
jointly and severally liable under a Credit Document for the obligations 
(the "Primary Obligations") of another Loan Party primarily responsible 
for the performance of such Primary Obligations may not be enforceable; 
provided, however, the lack of such enforceability does not (i) limit in 


<PAGE>

any way the enforcability of any of the Primary Obligations and (ii) 
does not make the principal remedies afforded by such Credit Document 
inadequate for the practical realization of the principal rights, 
benefits or security provided thereby.

5.4.  Approvals

     To the Company's actual knowledge, no authorizations, approvals or 
consents of, no filings or registrations with, and notices to any 
Governmental Authority are necessary for the execution, delivery or 
performance by the Company and the other Loan Parties of the Credit 
Documents, and the Acquisition Documents to which any of them is a party 

or for the validity or enforceability thereof, except for (a) filings 
and recordings in respect of the Liens created pursuant to the Security 
Documents, (b) such authorizations, approvals, consents, filings, 
registrations or notices as shall have been obtained.

5.5.  Financial Condition

     (a)  The Historical Financial Statements are materially complete 
and correct and fairly present the financial condition and results of 
operations of the Company and its Consolidated Subsidiaries as of and 
for the periods covered thereby.  There has been no material adverse 
change in the business, property, assets, liabilities, condition 
(financial or otherwise), operations, results of operations or prospects 
of the Company and its Subsidiaries taken as a whole since the date of 
the audited financial statements of the Company most recently delivered 
to the Lender under Section 4.1.(d) or 6.1.(a), as applicable.

     (b)  Except as set forth on Schedule 5.6. or in the financial 
statements most recently delivered to the Lender under Section 6.1.(a) 
or (b), to the Company's actual knowledge the Company and its 
Subsidiaries have no liabilities, contingent or otherwise, which could 
reasonably be expected to have a Material Adverse Effect.

     (c)  To the Company's actual knowledge (i) the Acquisition 
Historical Financial Statements of the Seller fairly present the 
financial condition and results of operations of the Seller as of and 
for the periods covered thereby; (ii) the Acquisition Pro Forma 
Financial Statements of the Seller, the Company and its Consolidated 
Subsidiaries fairly present the combined financial condition and results 
of operations of the Seller, the Company and its Consolidated 
Subsidiaries as of and for the periods covered thereby and (iii) there 
has been no material adverse change in the business, property, assets, 
liabilities, condition (financial or otherwise), operations, results of 
operations or prospects of the Seller since the end of such Seller's 
immediately preceding fiscal year.

5.6.  Litigation

     Except as set forth on Schedule 5.6. or in any written notice 
delivered by the Company pursuant to Section 6.1.(g)(D) or Section 6.2., 
there are no actions, suits or proceedings at law or in equity by or 
before any Governmental Authority now pending or, to the Company's 
actual knowledge, threatened against the Company or any other Loan Party 
or their respective business, property or rights (i) which involve any 

<PAGE>

Credit Document, any Acquisition Document or any Transaction or (ii) 
which, if adversely determined could reasonably be expected to, 
individually or in the aggregate, result in a Material Adverse Effect.  
There exists no judgment, order, injunction or other restraint issued or 
filed which is material to the Company or any other Loan Party, or any 
of their respective businesses, properties or rights, or which prohibits 
or adversely affects any of the Transactions.

5.7.  Federal Reserve Regulations

     Neither the Company nor any of the other Loan Parties is engaged in 
the business of extending credit for the purpose, whether immediate, 
incidental or ultimate, of buying or carrying Margin Stock.  No part of 
the proceeds of any extension of credit hereunder, whether directly or 
indirectly, and whether immediately, incidentally or ultimately, will be 
used (i) to purchase or carry Margin Stock or to extend credit to others 
for the purpose of purchasing or carrying Margin Stock or to refund 
indebtedness originally incurred for such purpose, or (ii) for any 
purpose which entails a violation of, or which is inconsistent with, the 
provisions of the Regulations of the Board of Governors of the Federal 
Reserve System, including Regulations G, T, U or X.  As used herein, the 
term "Margin Stock" shall mean margin stock within the meaning of 
Regulations G, T, U and X.

5.8.  ERISA

     (a)  Neither the Company nor any other Loan Party maintains or 
contributes to any Employee Benefit Plan or Multiemployer Plan other 
than those identified on Schedule 5.8. and those of which the Company 
has given written notice to the Lender after the date of this Agreement.

     (b)  The Company and each other Loan Party are in compliance in all 
material respects with all applicable provisions of ERISA and the Code 
with respect to all Employee Benefit Plans.  Each Employee Benefit Plan 
that is intended to be qualified under Section 401(a) of the Code has 
been determined by the Internal Revenue Service to be so qualified, and 
each trust related to such Plan has been determined to be exempt from 
federal income tax under Section 501(a) of the Code.  The actuarial 
present value of all accumulated benefit obligations under each Plan, as 
disclosed in the most recent actuarial report with respect to such Plan, 
does not exceed the fair market value of the assets of such Plan.  No 
material liability has been incurred by the Company or any other Loan 
Party or any of their ERISA Affiliates which remains unsatisfied for any 
taxes, penalties or other amount (other than contributions in the 
ordinary course) with respect to any Employee Benefit Plan or any 
Multiemployer Plan, and to the Company's actual knowledge no such 
material liability is expected to be incurred.

     (c)  Neither the Company nor any other Loan Party has: (i) engaged 
in a nonexempt prohibited transaction described in Section 406 of ERISA 
or Section 4975 of the Code; (ii) incurred any liability to the PBGC 
which remains outstanding other than the payment of premiums and there 
are no premium payments which are due and unpaid; (iii) failed to make a 
required contribution or payment to a Multiemployer Plan; or (iv) failed 
to make a required installment or other required payment under Section 
412 of the Code, which, in the case of any of the immediately preceding 
clauses (i) through (iv), could reasonably be expected to have a 

<PAGE>

Material Adverse Effect.

     (d)  No ERISA Event has occurred or is reasonably expected to occur 
with respect to any Plan or Multiemployer Plan maintained or contributed 
to by the Company or any other Loan Party which could reasonably be 
expected to have a Material Adverse Effect.

     (e)  Except as set forth on Schedule 5.6. or in any written notice 
delivered by the Company pursuant to Section 6.2., no proceeding, claim, 
lawsuit and/or investigation is existing or, to the Company's actual 
knowledge, threatened concerning or involving any Employee Benefit Plan 
or Multiemployer Plan maintained or contributed to by the Company or any 
other Loan Party which, if adversely determined could reasonably be 
expected to, individually or in the aggregate, have a Material Adverse 
Effect.

5.9.  Taxes

     Each of the Company and the other Loan Parties has filed all 
federal income tax returns and all other tax returns and reports, 

domestic and foreign, required to be filed by it and has paid all taxes, 
assessments, fees and other governmental charges shown to be due and 
payable by it on such returns or reports, in each case, the failure of 
which to file or pay could reasonably be expected to have a Material 
Adverse Effect.  All such returns are true and correct in all material 
respects.  Each of the Company and the other Loan Parties has paid or, 
in the case of taxes which are not yet due and payable or are being 
contested in good faith, has provided adequate reserves for the payment 
of, all federal, state and foreign taxes applicable for all prior fiscal 
years and for the current fiscal year to the date hereof, the failure of 
which taxes to pay could reasonably be expected to have a Material 
Adverse Effect. There is no proposed tax assessment against the Company 
or any other Loan Party which could reasonably be expected to have a 
Material Adverse Effect.

5.10.  Investment Company Act

     Neither the Company nor any other Loan Party is an "investment 
company" nor a company "controlled" by an "investment company" within 
the meaning of the Investment Company Act of 1940, as amended.

5.11.  Public Utility Holding Company Act

     Neither the Company nor any other Loan Party is a "holding company" 
nor an "affiliate" of a "holding company" or a "subsidiary company" of a 
"holding company" within the meaning of the Public Utility Holding 
Company Act of 1935, as amended.

5.12.  Material Agreements

     Other than this Agreement, the other Credit Documents, the 
Acquisition Documents and except as set forth on Schedule 5.12. or in 
any written notice delivered by the Company to the Lender after the date 
of this Agreement, neither the Company nor any other Loan Party is a 
party to any agreement or instrument or subject to any corporate 
restriction that has resulted or could reasonably be expected to result 

<PAGE>

in a Material Adverse Effect.

5.13.  Environmental and Safety Matters

     Except as set forth on Schedule 5.13. or in any written notice 
delivered by the Company pursuant to Section 6.1.(g), and except for

in excess of $1,000,000:

     (a)  The Company and each of the other Loan Parties have obtained

Company's actual knowledge, threatened by any Person with respect to any 
alleged failure to obtain any Permits or any violation of any 
Environmental and Safety Laws, or with respect to the generation, 
treatment, storage, recycling, transportation, discharge or disposal, or any 
Release or threatened Release, of any Hazardous Materials.

     (d)  No property or facility now or previously owned or operated by 
the Company or any of the other Loan Parties has been, to the actual 
knowledge of the Company, or is presently operated by the Company or any 
of the other Loan Parties in a manner which requires permitting as a 
hazardous waste treatment, storage or disposal facility for purposes of 
RCRA or any analogous state law.

     (e)  None of the following is (i) present at any property or facility 
now owned or operated by the Company or any of the other Loan Parties or (ii)

transportation of any Hazardous Material to any location which is on the 
CERCLA National Priorities List (or proposed for such listing), the CERCLIS 
list or any similar state list or which is the subject of federal, state or 
local enforcement actions or other investigations which may lead to claims 
against the Company or any of its Subsidiaries under any Environmental and 
Safety Laws.

<PAGE>

     (h)  No oral or written notification of a Release of a Hazardous 
Material has been made by or on behalf of the Company or any of the other 
Loan Parties and no property or facility now owned or operated by the Company 
or any of the other Loan Parties is on the CERCLA National Priorities List 
(or proposed for such listing), the CERCLIS list or any similar state list.  
To the Company's actual knowledge, no property or facility previously owned 
or operated by the Company or any of its Subsidiaries is on the CERCLA 
National Priorities List (or proposed for such listing), the CERCLIS list or 
any similar state list.

     (i)  No Liens have arisen under or pursuant to any Environmental and 
Safety Laws on any property or facility now owned or operated by the Company 
or any of the other Loan Parties, and no governmental actions have been taken 
or, to the Company's actual knowledge, are in process which could subject any 
such property or facility to such Liens.  To the Company's actual knowledge, 
no Liens have arisen under or pursuant to any Environmental and Safety Laws 
on any property or facility previously owned or operated by the Company or 
any of the other Loan Parties, and no governmental actions have been taken or 
are in process which could subject any such property or facility to such

the other Loan Parties have assumed, succeeded to or otherwise become liable 
(contingently or otherwise) for the obligations of any other Person pursuant 
to Environmental and Safety Laws, whether by contract, by operation of law or 
otherwise.

     (l)  To the Company's actual knowledge, without limiting the generality 
of the foregoing, there are no other facts, events or conditions relating to 
the past or present operations, properties or facilities of the Company or 
any of the other Loan Parties which may give rise to any liability under any 
Environmental and Safety Laws.

     To the extent any of the foregoing representations in this Section 5.13. 
relate to a property or facility acquired pursuant to a Purchase Agreement, 
such representations are based only on the actual knowledge of the Company.

5.14.  Subsidiaries

     Except as set forth on Schedule 5.16. or in any written notice delivered 
by the Company pursuant to Section 6.1.(q), the Company has no Subsidiaries, 
and except as set forth on such Schedule, all other Loan Parties are

assets of the FSC does not exceed 5.0% of the book value of the total 
consolidated assets of the Company and its Subsidiaries.

all Applicable Laws of, and all applicable restrictions imposed by, all 
Governmental 

<PAGE>

Authorities in respect of the conduct of their respective business and the 
ownership of their respective property (including Applicable Laws relating to 
environmental standards and controls), except such noncompliance as could not 
reasonably be expected to individually or in the aggregate, have a Material 
Adverse Effect.  Each of the Company and its Subsidiaries has all Regulatory 
Permits that are required by its customers for the operation of each of the 
Donor Centers as such Donor Centers are currently or anticipated to be 
operated except for Regulatory Permits the failure of which to have could not 
reasonably be expected to have a Material Adverse Effect.  

5.16.  Capitalization

the corporate structure and ownership interests of each of the Loan Parties 
(other than the Company), including the correct legal name of each such Loan

5.17.  Title to Properties

     Except as set forth on Schedule 5.17. or in any written notice delivered

Lender notice of the filing or commencement of, or any written notice of 
intention of any Person to file or commence, any action, suit or proceeding

could reasonably be expected to result in liability to the Company or any of 
the other Loan Parties in an amount equal to or exceeding $2,000,000.00 
(including the amount of any deductible paid or required to be paid by the 
Company or any other Loan Party under the terms of its insurance policies, 
but net of any amounts acknowledged in writing by the applicable insurer(s) 
to be fully covered 

<PAGE>

by insurance) or would otherwise have a Material Adverse Effect, and of any 
adverse development in respect of such legal or other proceedings.

6.3.  Corporate Existence, Etc.

     Except as not prohibited by this Agreement: preserve and maintain its 
corporate existence, and all of its material rights, privileges and 
franchises, including without limitation, obtaining and maintaining all 
necessary FDA approvals and QPP certification for all of its Donor Centers; 
comply in all material respects with the requirements of all Applicable Laws, 
rules, regulations and orders of all Governmental Authorities; maintain all 
of its material properties used in its business in sufficient working order 
and condition so as to permit such Loan Party to conduct its business; and 
preserve and enforce its rights (including rights to indemnification) under 
any Material Contracts, except where the failure to do so would not have a 
Material Adverse Effect in the reasonable judgment of the Lender.

6.4.  Insurance

     Keep insured by financially sound and reputable insurers all property of 
a character usually insured by entities engaged in the same or similar 
business similarly situated against loss or damage of the kinds and in the 
amounts customarily insured against by such businesses and carry such other 
insurance as is usually carried by such businesses.  Without limiting the 
obligations of the Company and the other Loan Parties under the foregoing 
provisions of this Section, in the event the Company or any of the other Loan 
Parties shall fail to maintain in full force and effect insurance as required 
by the foregoing provisions of this Section or any of the other Credit 
Documents, then the Lender may upon notice to the Company or such other Loan 
Party, but shall have no obligation to, procure insurance covering the 
interests of the Lender in such amounts and against such risks as the Lender  
shall deem appropriate, and the Company shall reimburse the Lender in respect 
of any premiums paid by the Lender as provided in Section 10.3.(c).

6.5.  Obligations and Taxes

     Pay its Indebtedness and other obligations in accordance with their 
terms and pay and discharge promptly all taxes, assessments and governmental 
charges or levies imposed upon it or upon its income or profits or in respect 
of its property, and in any event before the same shall become delinquent or 
in default, as well as all lawful claims for labor, materials and supplies or 
otherwise which, if unpaid, might give rise to a Lien upon such properties or 
any part thereof which could reasonably be expected to have a Material 
Adverse Effect; provided, however, that such payment and discharge shall not 
be required so long as the validity or amount thereof shall be contested in 
good faith by appropriate proceedings which effectively stay the execution of 
any such Lien and the Company shall (or shall cause the applicable Loan Party 
to) set aside on its books adequate reserves in accordance with GAAP with 
respect thereto.

6.6.  Maintaining Records; Access to Properties and Inspections

     Maintain all financial records in accordance with GAAP and permit any 
representatives designated by the Lender upon reasonable notice to visit and 
inspect the properties of the Company or any of the other Loan Parties and to 
inspect their financial and business records and make extracts therefrom and 
copies thereof, all at reasonable times and in a manner so as not to 
unreasonably disrupt the operations of the Company or the other Loan Parties 
and 

<PAGE>

as often as reasonably requested, and permit the Lender or any 
representatives designated by the Lender upon reasonable notice to discuss 
the affairs, finances and condition of the Company or any of the other Loan 
Parties with the officers thereof and independent accountants therefor; 
provided, however, that (i) any representatives designated by the Lender 
shall be in the business of acting as crisis managers or business consultants 
and shall be bound by the same or similar internal policies with regard to 
confidential information as is the Lender, and (ii) the Lender or any 
representatives designated by the Lender shall not discuss the affairs, 
finances and condition of the Company or any of the other Loan Parties with 
the Company's independent accountants unless and until the Lender determines 
in its discretion that discussions directly with the Company or the officers 
of the Company have failed to satisfy the inquiries of the Lender or its 
representatives.  Not in limitation of the foregoing, the Company shall, and 
shall cause each of the other Loan Parties to, keep complete, accurate and 
detailed financial records with respect to all amounts of all Loans made 
available to any of the Subsidiaries by way of loans.

6.7.  Environmental and Safety Matters

For the purposes of protecting the Lender's security interest in the 
Collateral and preserving the Company's ability to satisfy its Obligations:

     (a)  Comply with all Environmental and Safety Laws applicable to it or 
any of its property or facilities in all material respects.

     (b)  Keep its properties and facilities free from any Liens which could 
reasonably be expected to have a Material Adverse Effect arising under any 
Environmental and Safety Laws.

     (c)  Respond promptly to any Release or threatened Release of any Hazardous
Materials in a manner which complies in all material respects with all
Environmental and Safety Laws and mitigates any associated risk to human health
or the environment to the maximum extent commercially practicable.

     (d)  If the Lender at any time has reason to believe that any property 
or facility owned or operated by the Company or any other Loan Party has been 
or may be either (i) operated in violation of any Environmental and Safety 
Laws; (ii) contaminated with any Hazardous Materials; or (iii) subject to any 
government-imposed obligation to conduct any environmental investigation or 
clean-up, any of which, in the good faith judgment of the Lender may impair 
in any material respect the value of the Collateral or the ability of the 
Company or any of the other Loan Parties to satisfy any of their respective 
Obligations, the Company shall, upon the written request of the Lender, at 
the Company's sole cost and expense, conduct such investigation or study, 
through retention of a consulting firm reasonably satisfactory to the Lender, 
as is necessary in the good faith judgment of the Lender to demonstrate that 
no such impairment could reasonably be expected to have a Material Adverse 
Effect.

6.8.  Additional Security

     If and to the extent requested by the Lender from time to time, after the 
occurrence and during the continuation of a Default or Event of Default, execute
and deliver such additional documents and take such other action as may be 
necessary or desirable in the reasonable opinion of the Lender in order to 
assure and confirm that all Obligations are secured in a manner acceptable to 
the Lender by a first priority Lien on substantially all present and future 
assets of the Company and the other Loan Parties (other than Bioscot and the 


<PAGE>

FSC) subject only to Permitted Liens.

6.9.  Deposit Accounts/Cash Management Services

     For the purpose of protecting the Lender's security interest in the 
Collateral and enabling the Lender to monitor the proceeds of Collateral and 
the uses of cash by the Company and the other Loan Parties, maintain all of 
its primary operating accounts and treasury management service relationships 
with the Lender.

                                7.NEGATIVE COVENANTS

then-outstanding principal amount of, and the accrued interest on, the Loans 
and all other Obligations payable by the Company hereunder and under the 
Notes (including, without limitation, any amounts payable under Section 
10.3.) to be forthwith due and payable, whereupon such amounts shall be 
immediately due and payable without presentment, demand, protest or other 
formalities of any kind, all of which are hereby expressly waived by the 
Company; (2) in the case of the occurrence of an Event of Default referred to 
in Section 9.6. or Section 9.7. above, the Credit Facility shall 
automatically be canceled and the then-outstanding principal amount of, and 
the accrued interest on, the Loans and all other Obligations payable by the 
Company hereunder and under the Notes (including, without limitation, any

remedies available under the Security Documents or under Applicable Law.  The 
proceeds of any sale of the whole or any part of any of the Collateral as a 
result of an Event of Default, together with any other moneys paid to or held 
by the Lender under the provisions of any Credit Document, shall be applied 
by the Lender in the following order:

     (a)  First:  to the payment of all costs and expenses incurred in

     No failure on the part of the Lender to exercise and no delay in 
exercising, and no course of dealing with respect to, any right, power or 
privilege under this Agreement or any Note or other Credit Document shall

right, power or privilege under this Agreement or any other Credit Document

10.3.  Expenses, Etc.

     (a) Agreement to Pay and Reimburse.  The Company agrees to pay or 
reimburse the Lender for: (i) all out-of pocket costs and expenses 
(including, without limitation, the reasonable fees and expenses of Alston & 
Bird LLP, special counsel to the Lender) in connection with (A) the

other Credit Documents and the extension of credit hereunder and (B) any 
amendment, modification or waiver of any of the terms of this Agreement or 
any of the other Credit Documents; (ii) all costs and expenses of the Lender

incurred in connection with any filing, registration, recording or perfection

Document or any other document referred to herein or therein.

     (b)  Indemnity.  The Company agrees to indemnify the Lender and its 
directors, officers, employees and agents for, and hold each of them harmless 
against, any and all losses, liabilities, claims (including Environmental 
Claims), damages or expenses incurred by any of them arising out of or by 
reason of any investigation or litigation or other proceedings (including any 
threatened investigation or litigation or other proceedings) relating to the 
extensions of credit hereunder or any actual or proposed use by the Company 
or any Loan Party of the proceeds of any of the extensions of credit 
hereunder or the past, present or future business activities of the Company 
or any Loan Party including, without limitation, the reasonable fees and 
disbursements of counsel incurred in connection with any such investigation 
or litigation or other proceedings (but excluding any such losses, 
liabilities, claims, damages or expenses that are determined pursuant to a 
final, non-appealable order of a court of competent jurisdiction to have 
resulted solely from the gross negligence or willful misconduct of the Person 
to be indemnified).

     (c)  Expenses Paid On Behalf of the Company.  If the Company fails to 
pay when due any costs, expenses or other amounts payable by it under any 
Credit Document, including, without limitation, fees and expenses of counsel, 
indemnities and insurance premiums, such amount may be paid on behalf of the 
Company by the Lender, in its sole discretion.  Any such payment by the 
Lender shall constitute for all purposes of this Agreement the making by the 
Lender of a Loan, which shall bear interest at the Base Rate, in the amount 
of such payment (but without any requirement for compliance with the 
conditions set forth in Article 4.).  In the event that such payment is not 
reimbursed by the Company by 12:00 noon Atlanta, Georgia time on the first 
Business Day after such payment, the Lender shall be deemed to have made a 
Loan to the Company in such amount, which Loan shall be deemed to bear

such Loan is made until the same is repaid.

10.4.  Amendments, Etc.

termination, of any Loan, (ii) extend the date fixed for the payment of 
principal of or interest on any Loan or any Obligation hereunder, (iii) 
reduce the amount of any such payment of principal, (iv) reduce the rate at

hereunder, (v) alter the rights or obligations of the Company to prepay 
Loans, (vi) alter the terms of this Section or Section 10.6.(a), or (vii) 
waive any of the conditions precedent set forth in Article 4.

parties hereto and their respective successors and permitted assigns.

(a "Participant") a participation in all or any part of any Loans held by it, 
in which event the Participant's rights in respect of such participation 
shall be those set forth in the agreements executed by the Lender in favor of 
the Participant, and such Participant shall have no direct right under the 
Credit Documents.  In no event shall the Lender that sells a participation 
agree with the Participant to take or refrain from taking any action 
hereunder or under any other Credit Document, except that the Lender may 
agree with the Participant that it will not, without the consent of the 
Participant, agree to (i) increase or extend the term, or extend the time or 
waive any requirement for the reduction or termination, of the Revolving 
Commitment, the Swingline Commitment or the Credit Facility, (ii) extend the

any Subsidiary in the possession of the Lender from time to time to assignees 
and Participants (including prospective assignees and Participants) in 
accordance with its internal policies with regard to confidential 
information, provided that such assignees or Participants are bound by the 
same or similar internal policies with regard to confidential information as 
is the Lender.

10.7.  Survival

     The obligations of the Company and its Subsidiaries under Sections 3.4.

other jurisdiction) that would cause the application of the laws of any 
jurisdiction other than the State of Georgia.  In furtherance of the

COMMENCEMENT OF SUCH HEARING FOR UP TO AN ADDITIONAL 60 DAYS.

     B.  RESERVATION OF RIGHTS.  NOTHING IN THIS AGREEMENT SHALL BE DEEMED TO 
(I) LIMIT THE APPLICABILITY OF ANY OTHERWISE APPLICABLE STATUTES OF

IN ANY SUCH ACTION, TO ARBITRATE THE MERITS OF THE CONTROVERSY OR CLAIM 
OCCASIONING RESORT TO SUCH REMEDIES.

to the Borrower pursuant to, and in accordance with the terms of, the Credit
Agreement.
     
     The Borrower agrees to pay principal at said office, in like money, from
time to time on the dates and at the times specified in the Credit Agreement. 
The Borrower further agrees to pay interest at said office, in like money, on

Borrower under the Credit Agreement, and each payment of principal thereof,
shall be recorded by the Lender on its books and, prior to any transfer of this
Note, endorsed by the Lender on Schedule I attached hereto; provided, however,
that the failure of the Lender to make any such recordation or endorsement shall
not affect the obligation of the Borrower to make a payment when due of any
amount owing under this Note.  Any such recordations or endorsements made by the
Lender on its books or this Note shall be conclusive and binding on the Borrower
absent manifest error.
     
     This Note is the "Revolving Note" referred to in that certain Second

and not defined herein shall have the respective meanings given to such terms in
the Credit Agreement.  The Credit Agreement, among other things, (a) provides
for the making of Revolving Loans by the Lender to the Borrower from time to
time in an aggregate amount not to exceed at any time outstanding the Dollar
