PART I

Item 1. BUSINESS

The Company

V.I. Technologies, Inc. (VITEX or the Company) is a leading developer of a
broad portfolio of blood products and systems which use its proprietary viral
inactivation technologies. The Company's technologies are intended to address
the risks of viral contamination in blood products, including plasma, plasma
derivatives, red blood cells and platelets. Viral inactivation processes have
the potential to eliminate viruses that are enveloped by lipid membranes such as
hepatitis B virus (HBV), hepatitis C virus (HCV) and HIV, the virus that causes
AIDS, and non-enveloped viruses such as hepatitis A virus (HAV) and parvovirus
and other known and unknown pathogens.

The Company currently manufactures two human therapeutic products:

. PLAS+SD. The Company has entered into a collaboration agreement with the
American National Red Cross (Red Cross), whereby the Red Cross is the exclusive
distributor of the Company's PLAS+SD in North America. PLAS+SD, the first of the
Company's virally inactivated products, received marketing clearance from the
FDA on May 6, 1998. Commercial scale production and sale of PLAS+SD, a pooled
transfusion plasma which utilizes the Company's solvent/detergent (SD) viral
inactivation technology to inactivate lipid enveloped viruses, began in June
1998. PLAS+SD was the first, and is the only FDA approved, virally inactivated
blood component available for use in the United States.

. VITEX Plasma Fractions. The Company supplies VITEX Plasma Fractions,
primarily to Bayer Corporation (Bayer), under a collaboration arrangement. The
Company utilizes a combination of fractionation procedures and chromatographic
techniques to separate and purify the protein components of plasma. The plasma
fractions are further processed by the Company's customers into virally
inactivated plasma derivatives for use in FDA-approved therapeutic applications.

The Company's other virally inactivated blood products are all under
development and include:

. Universal PLAS+SD. Universal PLAS+SD is a product which is intended to
provide the same benefits as PLAS+SD without the need for matching donor and
recipient blood types. Under the Company's collaboration agreement with the Red
Cross, the Red Cross has a right of first offer to distribute this product if it
is approved by the FDA.

. Universal PLAS+SD II. Universal PLAS+SD II is intended to improve upon
Universal PLAS+SD by adding a second method of viral inactivation to inactivate
both enveloped and non-enveloped viruses.

. VITEX Fibrin Sealant. VITEX Fibrin Sealant, which is currently in Phase III
clinical trials, is designed for use during surgical procedures to augment or
replace sutures or staples for wound closure. The Company has collaborated with
United States Surgical Corporation (U.S. Surgical) to develop and distribute
this product.

. VITEX RBCC Systems. The Company has entered into strategic collaboration
agreements with Pall Corporation (Pall) for the development and marketing of
VITEX RBCC Systems which employ the Company's technologies to broadly inactivate
viruses and other pathogens in red blood cell concentrates.

VITEX's mission is to enable the global availability of safe blood products
using the Company's proprietary viral inactivation systems. To achieve this
objective, the Company intends to: (i) expand its technological leadership; (ii)
build a broad product portfolio; and (iii) leverage existing manufacturing
capabilities and regulatory expertise. VITEX believes that the sales, marketing
and distribution agreements that have been established with its strategic
collaborators can accelerate the commercialization of the Company's products.

The Company's predecessor, Melville Biologics, Inc., was formed more than 15
years ago by New York Blood Center, Inc. (NYBC), a world leader in research and
development in the fields of hematology and transfusion medicine, to process
plasma fractions and derivatives, and to facilitate its research efforts. V.I.
Technologies, Inc. was incorporated in Delaware in December 1992. Effective
January 1, 1995, pursuant to a transfer agreement between the Company and the
NYBC, the NYBC transferred to the Company substantially all of the assets of
Melville Biologics, including a cGMP manufacturing facility used

1


primarily to produce plasma fractions and related operating and product licenses
and certain other specified tangible and intangible assets, as well as various
contracts and the assumption of certain obligations of the NYBC related to such
assets and contracts. As a result of its spin-off from the NYBC, the Company
became the licensee of a substantial portfolio of patents and patent
applications held by the NYBC, including those related to the use of the SD
viral inactivation technology. In exchange for these net assets, the NYBC
received all of the issued and outstanding Common Stock of the Company.


Background

Whole blood contains important therapeutic components, including red blood
cells, platelets and plasma. Each of these components can be transfused directly
into patients. Plasma may also be fractionated into plasma fractions, which in
turn can be purified into protein products, referred to as plasma derivatives.
The worldwide blood products market is comprised of the blood components market
and the plasma derivatives market, as illustrated by the following diagram:

The Blood Components Market

Blood Components. Each of the components of blood serves specific functions.
Red blood cells, which transport oxygen and carbon dioxide throughout the body,
are frequently administered to patients who have anemia, trauma, surgical
bleeding or genetic disorders and account for the majority of transfusions.
Platelets, which initiate blood clotting and facilitate the repair of damaged
blood vessels, are often used to treat cancer patients following chemotherapy
and patients who lose large volumes of blood as a result of trauma or during
surgery. Plasma is the liquid part of the blood that contains a large number of
proteins, several of which have important therapeutic applications, including
mediating and controlling blood clotting, providing immune protection, and
treating several rare and life-threatening diseases such as thrombotic
thrombocytopenic purpura (TTP). White blood cells, an additional component of
blood, are comprised of many different types of cells that form part of the
body's immune system and are active in wound repair. White blood cells are
rarely transfused because of the potential for an adverse immune response by the
recipient.

Collection and Processing. The participants in the blood components market
collect and process whole blood from donors at either mobile or fixed collection
sites. Approximately 35 million whole blood donations occur in North America,
Western Europe and Japan annually. In the United States, approximately 45% of
donated blood is collected by the Red Cross, another 45% is collected by
independent community blood centers and the remaining 10% is collected by
hospitals.

2


Whole blood is usually separated by blood banks into red blood cells,
platelets and plasma to optimize transfusion therapy and to efficiently allocate
the limited available blood supply. These blood components are then distributed
by blood collection centers to hospitals for storage and subsequent transfusion.
Red blood cells and platelets each have a very short shelf life, of 42 and 5
days, respectively. Plasma can be frozen and stored for up to one year after
being collected in the form of fresh frozen plasma (FFP).

Transfusions. The Company projects that approximately 30% to 40% of the United
States population will receive a transfusion at some point during their
lifetime. Transfusions containing one or more blood components are often
required to treat diseases or disorders and to replace blood loss resulting from
trauma or during surgery. In the United States, over 11.3 million units of red
blood cells are transfused annually, while annual platelet and plasma
transfusions account for approximately 8.0 million units and 2.8 million units,
respectively. The average unit price paid by hospitals for red blood cells,
platelets and plasma is estimated to be approximately $85, $50 and $50,
respectively, and varies depending on geographic and other factors.

The Plasma Derivatives Market

Plasma Derivatives. Plasma contains a large number of proteins, several of
which are well characterized and have FDA-approved therapeutic applications.
These proteins are separated and purified into plasma derivatives through a
combination of fractionation procedures and modern chromatographic techniques.

Collection and Processing. Approximately 80% of plasma used for fractionation
in North America is collected from paid donors by plasmapheresis. After plasma
is collected from donors, it is frozen and shipped to large processing
facilities where fractionators purify, virally inactivate, sterile fill and
package protein products. Plasma derivatives are then sold to hospitals where
they are administered to patients. Four plasma fractionators, Bayer, Centeon
L.L.C., Alpha Therapeutics, and Baxter Corporation, currently account for almost
50% of the worldwide plasma derivatives market. These plasma fractionators are
currently operating at or near manufacturing capacity. The large capital costs
involved in establishing fractionation capacity and the regulatory approvals
necessary to manufacture and sell fractionated products may tend to restrict the
entry of new participants into the market.

Applications. Plasma derivatives have widespread therapeutic applications.
Albumin is frequently used as a volume expander to treat high volume blood loss,
which occurs during surgical procedures. Factor VIII and Factor IX concentrates
are routinely administered to patients with hemophilia. Immunoglobulins,
including formulations for intravenous administration, have been embraced for
the prevention and treatment of viral infections in immunocompromised patients
and in treating certain autoimmune disorders. The market for plasma derivatives
delivered to hospitals in 1994 was approximately $1.1 billion in the United
States and approximately $4.6 billion worldwide.

Challenges Facing the Blood Products Market

The use of plasma and plasma derivatives has increased dramatically in the
United States over the past two decades. In its July 1998 issue, the periodical
"Transfusion" reported that fresh frozen plasma (FFP) usage increased by over
16% between 1992 and 1994. While plasma and its derivatives represent a valuable
and lifesaving resource, these products have transmitted infectious agents to
recipients, most notably HIV, HBV and HCV. The viral safety of transfused blood
products relies on the dual safeguards of careful donor screening and rigorous
viral testing of donations.

Safety of the Blood Supply. Despite the many benefits that blood products
provide, and recent improvements in testing and processing of blood, concerns
remain over the presence of viruses, bacteria and parasites in donated blood.
Viruses such as HBV, HCV, HIV, cytomegalovirus (CMV) and human T-cell
lymphotropic virus (HTLV) can present life-threatening risks. In addition,
bacteria and many other agents can transmit disease during transfusion,
including the bacteria which can cause sepsis or other systemic infections which
can result in serious illness or even death. The parasites that cause malaria
and Chagas' disease may also be transmitted by transfusions.

The risk of transmission of any of these pathogens from an infected donor is
compounded by a number of factors, including: (i) dividing a unit of infected
blood into its components which may expose several patients to the pathogen;
(ii) deriving therapeutic quantities of blood components from typically two to
eight donor units, any one of which may contain pathogens; and (iii)
administering frequent transfusions to certain patient populations, such as
patients with cancer, suppressed immune systems, congenital anemia and kidney
and liver disorders, resulting in a heightened risk of infection due to multiple

3


transfusions. The following table illustrates the current risks of exposure to
the major, identified pathogenic viruses in transfused blood.

(1) Such as patients who have had surgery or trauma.
(2) Such as patients who have cancer, liver disease and sickle cell anemia.

Emerging and unidentified pathogens also present a threat to the blood supply,
illustrated by the recent history of HIV contamination. It is estimated that HIV
was present in the blood supply for at least seven years before it was
identified as the causative agent of AIDS and at least eight years before a test
was commercially available to detect the presence of HIV antibodies in donated
blood. During those years, many transfusion recipients were infected with HIV,
including approximately 70% of patients with severe hemophilia. In addition,
approximately 4 million Americans are infected with HCV. 85% of those infected
develop chronic liver disease and approximately 10-20% develop cirrhosis of the
liver. Of these 4 million people, more than one million have received
potentially HCV infected blood or blood products. Moreover, most tests to detect
viruses are antibody tests, which detect an immune response to the virus, rather
than the virus itself. As a result, these tests fail to detect viruses when
performed during the "infectivity window" early in the course of an infection
before antibodies appear in detectable quantities.

Product Consistency. Unlike pharmaceutical products, blood components vary in
their consistency, creating uncertainty as to proper dosing. This occurs as a
result of: (i) the variability of component concentrations among donors; (ii)
the impracticality of selecting donors with the optimal blood component profile;
and (iii) the imprecision in the processes for collecting and separating red
blood cells, platelets and plasma. Large plasma fractionators achieve high
consistency by processing plasma from multiple donors in a single batch and
through processing under controlled conditions.


Approaches to the Safety of the Blood Supply

There are several approaches to improving blood safety currently available and
under development, including the following:

Screening. The screening of blood and blood components for known pathogens is
universally accepted. However, there are many reasons why screening cannot
ensure a safe blood supply, including the following: (i) failure of tests during
the infectivity window; (ii) limitations of test sensitivity where tests cannot
detect a small quantity of virus or antibody; (iii) limitations of test
specificity where tests fail to detect certain viral variants; (iv) the presence
of new viruses that have not been identified and for which no test exists; (v)
the presence of identified viruses for which no test is available; and (vi)
human error.

Donation Strategies. Autologous (self) donation avoids the risk of receiving
contaminated donor blood, but is impractical for most patients. Quarantining of
blood seeks to address the problems associated with the infectivity window by
storing a donor's blood for three to six months after which time the donor must
return for additional testing. However, quarantining depends on the donor's
timely return for additional testing, cannot be applied to red blood cells or
platelets because of their limited shelf life and is subject to limitations
associated with blood screening.

Blood Substitutes. Several companies are developing synthetic "blood
substitutes." However, blood substitutes may be less effective in certain
indications than the blood components they are intended to replace, and may be
missing important blood factors, including those utilized for blood clotting,
immune surveillance and wound healing.

Viral Inactivation. Viral inactivation has been used successfully for plasma
derivatives worldwide since the mid-1980's and for the treatment of transfusion
plasma in Europe since the early 1990's. Viral inactivation has the potential to
inactivate both known and unknown viruses. Viral inactivation for cellular blood
components, such as red blood cells, is still under development.


Products and Product Development

VITEX has developed and is further developing a comprehensive portfolio of
blood products and systems using its proprietary viral inactivation
technologies. In addition to SD technology, which inactivates lipid-enveloped
viruses in protein solutions, the Company is developing several other viral
inactivation technologies. These additional technologies include an irradiation
technology that uses short wavelength ultraviolet light (UVC) to inactivate both
enveloped and non-enveloped viruses in protein solutions, photodynamic
technology that uses light-activated compounds (LAC) to inactivate viruses in
red blood cell concentrates, quencher (Quencher) technology that utilizes
antioxidants to prevent damage to the therapeutic proteins in blood derivatives
and to cells from use of UVC and LAC technologies. Additionally, the Company is
evaluating technologies including chemical compounds to inactivate both
enveloped and non-enveloped viruses in plasma. The following table identifies
the Company's principal products and product development programs:

(1) SD technology is used by the Company's customers under non-exclusive
licenses from the NYBC to virally inactivate certain plasma derivatives
manufactured from fractions supplied to them by the Company.
(2) The Red Cross has a right of first offer to distribute these products.


Plasma Derivatives

VITEX Plasma Fractions. VITEX is currently producing and selling commercial
quantities of its VITEX Plasma Fractions, principally to Bayer, one of the four
major providers of plasma derivatives worldwide. Bayer purifies and virally
inactivates

5


certain of these fractions using SD technology and packages these plasma
fractions as final plasma derivatives products. Because most blood products
processors have been licensed by the NYBC to use SD technology in the
manufacture of virally inactivated plasma derivatives, the Company's strategy
has been to be a supplier to, rather than a competitor of, these plasma
fractionators. The Company's Processing Agreement with Bayer is structured as a
multi-year, "take-or-pay" supply agreement.

Plasma Derivatives Market. The principal products derived from plasma are
albumin, Factor VIII and Factor IX and immunoglobulins. The market for plasma
derivatives was estimated to be approximately $1.1 billion in the United States
and approximately $4.6 billion worldwide in 1994. The Company believes that
worldwide demand for plasma derivatives is increasing at a rate of 10-20%
annually, due primarily to an aging population requiring more medical care, the
discovery of new clinical applications for existing products derived from
plasma, and the development of new products such as fibrin sealants and other
bioadhesives. While the demand for plasma derivatives is increasing, each of the
four major fractionators, Bayer, Centeon, Alpha Therapeutics and Baxter, is
currently operating at or near manufacturing capacity. Because of the
substantial capital expenditures and time associated with the construction,
validation and licensing of fractionation facilities, the Company believes that
demand for its fractionation capacity will remain high for the foreseeable
future.

The NYBC processed plasma fractions and derivatives from 1970 through 1993.
Following its spin-off from the NYBC in 1995, the Company began processing
plasma fractions and has since expanded this business. The NYBC received an
Establishment License from the FDA for a new manufacturing facility in 1980. The
NYBC received product licenses from the FDA for the manufacture of albumin,
Factor VIII and immunoglobulins. All FDA approvals originally granted to the
NYBC were assigned to the Company at the time of its formation.


Transfusion Plasma

PLAS+SD. PLAS+SD, which serves as a virally inactivated substitute to FFP, was
approved for marketing by the FDA on May 6, 1998. While virally inactivated
plasma fractions have been commercially available since 1985, PLAS+SD was the
first and is currently the only virally inactivated blood component, as opposed
to virally inactivated plasma fractions, marketed in the United States. PLAS+SD
is a transfusion plasma treated with the SD viral inactivation process which
virtually eliminates the transmission of HIV, HBV, HCV and all other lipid-
enveloped viruses transmitted via plasma transfusions, which present the most
significant viral risks from blood transfusions. Its labeled uses are the same
as those for FFP and include the treatment of certain coagulation factor
deficits and thrombotic thrombocytopenic purpura, a disease characterized in
part by a low platelet count. VITEX holds an exclusive license in North America
and a non-exclusive license in the rest of the world excluding Europe from the
NYBC to apply the proprietary SD process to the viral inactivation of plasma.
The SD viral inactivation process used for PLAS+SD achieves rapid and complete
viral killing of lipid-enveloped viruses transmitted by transfusion, while
retaining the normal functional performance characteristics expected from FFP.
Since PLAS+SD is a pooled product, it offers the advantages of relatively
uniform composition from lot to lot (FFP is much more variable in its
coagulation factor content), and there is a wider variety of immunoglobulins
(antibodies) present that may protect against other diseases, such as HAV and
parvovirus B-19. Phase IV clinical studies are currently underway to support
the neutralizing or protective properties of the antibodies to HAV and B-19 in
PLAS+SD.

Under the agreement with the Red Cross, the Red Cross acts as the exclusive
distributor of PLAS+SD in North America, provided that the Red Cross purchases
from the Company certain stated minimum quantities of PLAS+SD.

Transfusion Plasma Market. FFP is the component of blood used primarily in the
treatment of certain coagulation factor deficits. FFP is a source of all blood
clotting factors except platelets and is used to control bleeding in patients
who require clotting factors, such as patients undergoing surgical transplant or
other extensive medical procedures and patients with chronic liver disease or
certain genetic clotting factor deficiencies. The production of FFP in 1995 is
estimated to have been 2.7 million units in North America, 2.7 million units in
Western Europe and 5.2 million units in Japan. The average unit selling price
for FFP in North America is currently estimated by the Company to be $50. The
FFP market is currently served by the Red Cross and by more than 100 independent
blood centers in the United States.

Regulatory Status. The Company received marketing approval from the FDA on May
6, 1998, and began commercialization of the product in June 1998. The Company's
filing for registration of PLAS+SD in Canada is currently pending regulatory
approval. The SD viral inactivation process does not inactivate non-enveloped
viruses. Two such non-enveloped viruses that have been reported to be
transmitted by blood products include HAV and human parvovirus B19. To date,
there have been no documented cases of HAV, parvovirus B-19 or any non-enveloped
viral infection as a result of

6


treatment with PLAS+SD. Phase IV efficacy studies are currently underway to
support the neutralizing or protective properties of the antibodies to HAV and
parvovirus B-19 in PLAS+SD.

Universal PLAS+SD. Universal PLAS+SD is a product under development by the
Company which is intended to improve upon PLAS+SD. In addition to having the
same characteristics and benefits as PLAS+SD, Universal PLAS+SD would eliminate
the need for matching donor and recipient blood types. Universal PLAS+SD is
prepared using patented technology, exclusively licensed from the NYBC, which
binds and removes specific antibodies present in donor plasma that would
otherwise cause an immune response in the recipient. VITEX has established the
feasibility of this approach and has initiated pre-clinical studies. The Company
expects to file an amendment to its current IND application for Universal
PLAS+SD in the first half of 1999.

Universal PLAS+SD II. Universal PLAS+SD II adds a second method of viral
inactivation to Universal PLAS+SD. In addition to inactivating enveloped
viruses, the Company is evaluating alternative technologies, including UVC and
chemical compounds, which are intended to inactivate known non-enveloped viruses
and may offer added protection against other non-enveloped viruses that might
contaminate the blood supply in the future. Although the presence of antibodies
normally found in pooled plasma protects against known non-enveloped viruses, SD
and these second generation technologies used in combination provide a higher
margin of blood product safety than SD technology alone. Universal PLAS+SD II is
at an early stage of development and, consequently, there can be no assurance
that the Company will be able to successfully develop, secure approval for or
commercialize this product.


Wound Care Products

VITEX Fibrin Sealant. The Company is developing its VITEX Fibrin Sealant for
use during surgical procedures to augment or replace sutures or staples for
wound closure. Fibrin sealants-also known as fibrin glues-are created by
combining the two principal clotting factors found in blood, fibrinogen and
thrombin, whose natural function is to halt bleeding and seal tissues. Fibrin
sealants are biodegradable, and their use does not generally elicit an immune
response frequently associated with non-biological glues. The Company expects
that its fibrin sealant will be the first doubly virally inactivated fibrin
sealant available in the United States. The Company's approach to viral
inactivation of its VITEX Fibrin Sealant is based on the use of its proprietary
double viral inactivation system, utilizing the Company's SD and UVC
technologies.

Fibrin Sealant Market. In Europe and Japan where fibrin sealants have been in
use for many years, these products have been shown to reduce the loss of blood
or other important bodily fluids and to produce less scarring when used as a
tissue adhesive as compared to conventional sutures. The Company estimates that
the market for fibrin sealants in Europe and Japan was $150 million and $200
million, respectively, in 1997. The Company estimates that the U.S. market for
fibrin sealants will be in excess of $350 million within five years. The first
fibrin sealant was approved for use in the U.S. during 1998.

Regulatory Status. VITEX submitted an IND application and commenced clinical
trials for VITEX Fibrin Sealant in late 1995. Initial Phase II trials were
designed to evaluate the safety and efficacy of VITEX Fibrin Sealant in patients
who have undergone modified radical mastectomy or lumpectomy in the treatment of
breast cancer. Eighty patients at five clinical sites participated in the
mastectomy/lumpectomy trial which was completed in late 1996. VITEX, in
collaboration with U.S. Surgical, commenced two Phase III trials at more than 20
sites in late 1997, one of which was a continuation of the evaluation of VITEX
Fibrin Sealant following breast cancer surgery. The other evaluates VITEX Fibrin
Sealant's ability to reduce blood loss following carotid artery surgery. At the
end of September 1998, the Company completed patient enrollment of the breast
surgery study and is currently evaluating the results. Enrollment in the
carotid artery surgery study is continuing and the Company expects to submit a
PLA for VITEX Fibrin Sealant during 1999. An additional Phase II study,
designed to evaluate the safety and efficacy of VITEX Fibrin Sealant in patients
suffering from non-healing rectal fistula, was successfully completed during
1998. During 1998, the Company completed construction of a multi-use
manufacturing suite within its existing facility to permit the production,
subject to FDA approval, of commercial quantities of VITEX Fibrin Sealant.
Validation of the new manufacturing area is currently underway.


Red Blood Cell Concentrates

The majority of blood product transfusions involve red blood cells. Red blood
cells deliver oxygen to and remove carbon dioxide from tissues. Red blood cells
are used in the care of patients with trauma, anemia and certain genetic
disorders. The

7


current worldwide market for red blood cell concentrates (RBCC) is estimated at
approximately $3.0 billion. In the United States alone, homologous (donation by
someone other than the recipient) RBCC transfusions exceed 11 million units
annually, with an estimated market value of $1.0 billion.

VITEX Red Blood Cell Concentrates The Company is developing virally
inactivated red RBCC based on the use of LAC that respond to specific
wavelengths of light. These viral inactivation procedures, which are performed
in combination with the Company's Quenchers, are designed to leave unaffected
the structure, function and circulatory persistence of the treated cells, thus
preserving the biological characteristics of these blood components. The
Company's lead light-activated compound, Pc4, has been shown to inactivate HIV
and the bovine virus used as a model for HCV, as well as the parasites that
cause Chagas' disease and malaria. In addition, Pc4-treated red blood cells have
exhibited an acceptable recovery and circulatory survival during pre-clinical
studies. The resulting product is expected to compare favorably to published
data on blood substitutes (e.g., hemoglobin solutions) whose functional
properties do not match those of intact red blood cells. VITEX expects to file
an IDE application for VITEX RBCC in 1999. The Company has entered into an
agreement with Pall regarding the development and distribution of systems for
the viral inactivation of RBCC.


Viral Inactivation Technology Platform

The Company's products are based on a portfolio of technologies which are
designed to be used either individually or in combination. Members of the
Company's scientific team developed the core VITEX viral inactivation
technologies while working at the NYBC. The NYBC subsequently licensed these
technologies to the Company. In addition, the Company continues to make
substantial investments in research and development to enhance the value of its
technology platform and has filed several patent applications as a result of
these activities. The technologies being developed by the Company are described
below:

The Solvent/Detergent (SD) Technology. Most pathogenic viruses found in blood,
including HBV, HCV and HIV, are protected by a lipid shell or envelope. The SD
process involves the addition of a chemical solvent (a di- or trialkyl
phosphate) and a detergent, which serves to enhance the contact between solvent
and virus, into pools of plasma or plasma fractions, which dissolves the lipid
shell of the virus, after which the virus can no longer bind to and infect
cells. The process is completed by removing the SD reagents, typically by
extraction with vegetable oil and hydrophobic chromatography, and sterile
filtering to remove bacteria, parasites and blood leukocytes and leukocyte
debris. In September 1998, the FDA's Blood Products Advisory Committee
recommended leukoreduction of blood components. This recommendation is now under
consideration by the FDA.

The SD process was first applied to plasma derivatives in 1985 for use in
patients with hemophilia. This process has become the most widely used method
for the inactivation of lipid enveloped viruses around the world and currently
is used, under license from the NYBC, by more than 50 plasma fractionators.
Since 1985, it is estimated that more than 15 million doses of SD-treated
Factors VIII and IX, and a total of over 35 million doses of all SD-treated
products, have been administered without a single reported case of HBV, HCV or
HIV transmission. Experience has demonstrated that plasma for transfusion, when
treated with the SD process, retains blood protein structure and function with
minimal loss of essential protein components and can be implemented cost-
effectively. In support of US Food and Drug Administration (FDA) licensure for
PLAS+SD in the United States, the Company conducted eight clinical studies in
over 31 medical centers. These studies were designed to evaluate the efficacy
and safety of PLAS+SD when used either to replace coagulation factors in
patients with a documented deficiency for which no specific coagulation factor
concentrate was available, or when used to treat patients with chronic or acute
thrombotic thrombocytopenic purpura (TTP). These trials demonstrated that with
PLAS+SD, coagulation factor recovery was normal following treatment, and
bleeding ceased where it was preexistent. Clotting times decreased in accord
with expectations when PLAS+SD was used to replace clotting factor deficiency.
In patients with TTP, clinical symptoms resolved. Side effects were
characteristics of those reported with FFP. Moreover, there was no evidence of
transmission of either lipid-enveloped or non-enveloped virus by the product.

Ultraviolet C Light (UVC) Technology. VITEX's proprietary short wavelength
ultraviolet light irradiation technology has been shown to inactivate both
enveloped and non-enveloped viruses in protein solutions. Viral inactivation
occurs because viral nucleic acids are modified directly when they absorb
ultraviolet light energy. Specificity results from differential absorption of
UVC by nucleic acids and proteins and the much larger target size presented by
nucleic acids. Quenchers added to plasma or plasma derivatives prior to
treatment serve as a source of antioxidant, preventing oxidative damage to
therapeutic proteins without interfering with viral inactivation.

8


Initial research and development of the UVC technology was conducted by the
Company's scientists at the NYBC and is being continued at VITEX. The research
and development effort includes the development of an irradiator which controls
UVC intensity and provides a fluid path for the plasma or plasma derivative
being treated. The Company is currently conducting Phase III clinical trials of
its VITEX Fibrin Sealant which employs SD and UVC technologies. The Company
intends to file a BLA for this product during 1999.

Light-Activated Compound (LAC) Technology. VITEX is developing photodynamic
technology that uses light activated compounds to inactivate viruses in red
blood cell concentrates. LAC technology is based on the use of specific
wavelengths of light and photosensitizers to initiate a series of reactions
leading to the inactivation of viruses. In addition, LAC technology has been
shown to inactivate parasites and bacteria in pre-clinical studies.

VITEX researchers have shown that many factors regulate the degree of viral
inactivation and associated cellular damage using LAC technology. These factors
include the selection of the specific photosensitizer, the addition of specific
Quenchers, the selection of light at the appropriate wavelength, the intensity
of the light source and the formulation of the photosensitizer. The Company has
available to it a wide variety of light-activated compounds for the treatment of
RBCC. RBCC are generally able to repair oxidative damage that typically
accompanies the use of LAC. One such class of LACs, the Company's proprietary
phthalocyanines, is particularly suited to the treatment of RBCC since the
wavelengths of light used to activate these photosensitizers are not absorbed by
red blood cells.

Quencher Technology. Treatment with UVC or LAC generates reactive oxygen
species (ROS) which can damage proteins and cells. VITEX has shown in pre-
clinical studies that inclusion of chemical antioxidants (Quenchers) during
viral inactivation quench or react readily with ROS to reduce damage to
therapeutic proteins and cells without interfering with inactivation of viruses
and other pathogens. As examples, under equally virucidal conditions, with the
inclusion of Quenchers, the yield of biologically active UVC-treated Factor
VIII, the in vivo survival of LAC-treated red cells and the yield of
biologically active LAC-treated platelets each improved 2.5 times. The Company's
Quenchers include rutin (a naturally occurring flavonoid found in many fruits
and vegetables), mannitol (a sugar), cysteine (a naturally occurring amino
acid), and vitamin E.


Strategic Collaborations

VITEX believes that it can efficiently accelerate the commercialization of its
products by collaborating with sales, marketing, distribution, and technology
partners. The Company has entered into collaborations with Bayer, the Red Cross,
U.S. Surgical and Pall, for development, licensing and marketing of the
Company's products and systems. As part of these agreements, the Company is
collaborating with U.S. Surgical and Pall for the development of certain of the
Company's products and systems. VITEX may seek to establish additional
collaborations with partners in other areas of strategic focus. The terms of the
Company's strategic collaborations are described below:

Bayer Corporation. The Company, as one of many non-exclusive licensees of SD
technology for viral inactivation of plasma fractions, does not itself use the
SD technology to virally inactivate plasma fractions. Rather than competing with
existing suppliers of virally inactivated plasma fractions, the Company has
decided to participate in the market for virally-inactivated plasma fractions by
providing plasma fractions to other parties for viral inactivation by such other
parties. In February 1995, the Company entered into an Agreement for Custom
Processing (the Processing Agreement) with Bayer, one of the largest processors
of blood plasma, to supply VITEX Plasma Fractions to Bayer. This Processing
Agreement was amended in January 1996, December 1997 and December 1998 to, among
other things, extend the term through 2001 and increase the volume of plasma
fractionated under this agreement through 1999. The term of the agreement is
automatically extended for two additional one-year periods unless Bayer notifies
VITEX within certain specified periods that it does not desire to extend the
agreement for either one-year period. During the period from January 3, 1999
through the remainder of the term in December 2001, the contract provides for
revenues to VITEX of approximately $19 million per annum, subject to the Company
meeting certain performance obligations. Incremental revenue, assuming the
arrangement is extended as permitted by the contract will be approximately $19
million during each of the years ending December 31, 2002 and 2003,
respectively. The Company received $14.7 million in revenue from Bayer during
the year ended January 2, 1999 under this agreement. Under the agreement, Bayer
is obligated to provide the Company with a specified quantity of plasma annually
during the term of the agreement and the Company is obligated to return plasma
fractions to Bayer within certain specified periods. The agreement is structured
as a take-or-pay arrangement under which Bayer is obligated to pay VITEX a fixed
fee per liter of fractionated plasma whether or not Bayer fulfills its
obligation to supply plasma to the Company. Certain of the plasma fractions
supplied to Bayer are virally inactivated by Bayer using the SD technology
licensed to Bayer by the NYBC. In the event that VITEX does

9


not provide fractions as required under the agreement, or upon the occurrence of
other events of default, Bayer has certain rights to take over and operate the
fractionation portion of the Company's production facility. As security for the
performance of the Company's obligations under the Bayer agreement, the Company
granted Bayer a mortgage on the Company's manufacturing facility, which Bayer
has subordinated to a subsequent mortgage granted by the Company to The Chase
Manhattan Bank, and a security interest in substantially all of the personal
property of the Company that is necessary or useful to the processing and
fractionation of Bayer supplied plasma. The Company may terminate the agreement
upon written notice of a material breach of the agreement and failure to cure by
Bayer. Bayer may terminate the agreement in certain circumstances including a
material breach of the agreement and failure to cure by the Company and an event
of default under the Company's credit agreement with its institutional lender.

American National Red Cross. In December 1997, the Company entered into a
supply, manufacturing and distribution agreement with the Red Cross (the Red
Cross Agreement) over a term of 57 months, for the Red Cross to become the
exclusive distributor of the Company's PLAS+SD in North America. Under the
agreement, the Red Cross, which is the largest supplier of transfusion plasma to
hospitals in the United States, providing about 45% of the transfusion plasma
used annually, is required to purchase stated minimum quantities of PLAS+SD to
maintain its exclusive rights. Once the Red Cross places its annual purchase
order with VITEX, it is obligated to supply VITEX with a sufficient quantity of
plasma to enable VITEX to fulfill the order. The Red Cross must pay for the
amount of PLAS+SD specified in the purchase order even if it is unable to supply
sufficient quantities of plasma. The Red Cross must purchase all of its virally-
inactivated plasma from the Company unless an FDA approved product has been
independently shown to be safer than PLAS+SD. The Company, in turn, is obligated
to offer any excess capacity that it has to produce PLAS+SD above the stated
minimum purchase requirements to the Red Cross before selling PLAS+SD to any
other party. Effective October 1, 1998, the Red Cross Agreement was amended to,
among other things, reduce the Red Cross's minimum annual purchase order
commitment required to maintain its exclusive marketing and distribution rights,
provide higher pricing during periods of lower volume purchases, and commit
increased marketing spending by both the Company and the Red Cross. Under the
amended agreement, the Red Cross is required to pay to the Company a fixed price
per unit of PLAS+SD, plus a royalty which is initially fixed. Beyond a specified
volume, the royalty becomes variable, based on equal sharing of the amount by
which the average selling price of the Red Cross exceeds a stated amount.
Anticipated revenue under the amended agreement is approximately $50 million
during the two year period ending September 30, 2000. The Company recorded
revenue of $16.3 million during the year ended January 2, 1999 under the
original and amended agreements. The Company has granted to the Red Cross a
right of first offer to acquire exclusive distribution rights to any subsequent
generation of virally inactivated transfusion plasma products that are developed
during the term of the agreement. The Company and the Red Cross have each
committed to spend minimum amounts for marketing PLAS+SD during the two year
period ending September 30, 2000. The Company's spending commitment is expected
to be satisfied, to a large extent, by the cost of its sales force.
Additionally, a joint marketing committee will coordinate all marketing
activities for PLAS+SD. The exclusive distribution agreement between the Company
and the Red Cross provides that the Red Cross will use its best efforts to
ensure availability of the Company's virally inactivated transfusion plasma
products to all potential customers, including Red Cross blood centers and non-
Red Cross blood centers.

Under a previous collaboration agreement, the Red Cross had made a total of
$3.0 million non-interest bearing, unsecured advances to the Company to be used
to fund improvements to the Company's manufacturing facility. Under this
previous agreement, the loan amortized at the rate of 15% per year following
receipt of marketing approval of PLAS+SD with a balloon payment due in year
five. In conjunction with the amended agreement, the repayment schedule was
modified to reflect repayment of 30% of the loan balance on the second
anniversary date of the approval of the PLAS+SD PLA and 15% of the balance on
each of the following two years, with the balance of the loan payable on the
fifth anniversary of the PLAS+SD PLA. Each of the Company and Red Cross has the
right to terminate the agreement upon written notice in certain circumstances,
including a material breach of the agreement which is not cured by the other
party.

United States Surgical Corporation. In September 1996, the Company and U.S.
Surgical entered into an exclusive worldwide distribution agreement, which was
amended in October 1996, regarding VITEX Fibrin Sealant for an initial period of
15 years. Upon entering into the agreement, U.S. Surgical paid a $3.0 million up
front fee to the Company. U.S. Surgical has agreed to fund all direct clinical
and regulatory costs associated with the development and regulatory approval of
VITEX Fibrin Sealant after the initial Phase II trial conducted by the Company.
In addition, in return for exclusive rights, U.S. Surgical has agreed, subject
to termination upon notice, to pay a substantial portion of agreed upon research
and development costs associated with any improvements or, enhancements to VITEX
Fibrin Sealant. Pursuant to this agreement, the Company granted U.S. Surgical
the mutually exclusive worldwide right, until October 2011, to seek, in its own
name as permitted by law, necessary government approvals for and to use, market,
distribute and sell fibrin sealants, and any improvements thereto which improve
the storage or reconstitution time of such products, for use in in vivo human
and veterinary medical applications. This

10


mutually exclusive distribution agreement further provides U.S. Surgical with a
first option to obtain exclusive distribution rights on any enhanced products
developed by the Company as well as certain other wound care products developed
in the future. U.S. Surgical must achieve certain minimum sales of the products
to maintain its exclusive rights under the agreement. Under the agreement, the
Company agrees to supply U.S. Surgical's forecasted demand for the products and
if it is unable to supply an agreed upon level in excess of such forecasted
demand, for a stated period, U.S. Surgical has an option to make arrangements to
have the excess demand for such products produced by third-party manufacturers.
Either the Company or U.S. Surgical may terminate the agreement upon written
notice in certain circumstances, including a breach of the agreement by the
other party which is not cured. U.S. Surgical may also terminate the agreement
for any reason upon nine months' notice to the Company. In January 1999, the
agreement was amended to reflect modified pricing terms for sale of the product
by the Company to U.S. Surgical. During 1998, the Company completed construction
of a multi-use manufacturing suite, within its existing facility, to permit the
production, subject to FDA approval, of commercial quantities of VITEX Fibrin
Sealant. Validation of the new manufacturing area is currently underway. U.S.
Surgical was recently acquired by Tyco Corporation. The effects, if any, of this
acquisition on the development programs and the eventual success of the product
cannot be assessed at this time.

Pall Corporation. In February 1998, the Company and Pall entered into a series
of agreements (the "Pall Agreements") providing for, among other things, a
collaboration on the development and marketing of systems employing the
Company's LAC and Quencher viral inactivation technologies for red blood cell
and platelet concentrates. Pall is a leading manufacturer and supplier of
filtration products, including those relating to the collection, preservation,
processing, manipulation, storage and treatment of blood and blood components.
VITEX will continue to develop its proprietary LAC and Quencher viral
inactivation technologies in collaboration with Pall's proprietary filtration
and processing technologies for pathogen removal in the treatment of red blood
cell concentrates. Under the Pall Agreements, Pall receives exclusive worldwide
distribution rights to any system incorporating any VITEX viral inactivation
technology for red blood cells and platelets. The parties have also agreed to
share research, development, clinical and regulatory responsibilities and will
equally share profits and joint expenses from operations after each party is
reimbursed for its cost of goods. Upon execution of the Pall Agreements in
February 1998, Pall acquired 477,042 shares of the Common Stock for $4.0 million
or $8.39 per share. Pursuant to the terms of the Pall Agreements, Pall acquired
$5 million of the Company's Common Stock in a private placement, which closed
contemporaneously with, and at the same price, terms, and conditions as the IPO.
In addition, the Pall Agreements provide that Pall will purchase up to $17
million of VITEX Common Stock in installments tied to the achievement of
specified development milestones in the development of VITEX RBCC and such
equity investments by Pall will be made at the prevailing market price per
share. Pursuant to the Pall Agreements, certain existing stockholders of the
Company have agreed to vote their shares to elect to the Board of Directors of
the Company a nominee designated by Pall. Certain of the Pall Agreements may be
terminated in certain circumstances including an event of default by either
party which, in the case of VITEX, includes the termination for any reason of
Dr. Bernard Horowitz's employment with the Company.


Manufacturing and Supply

The Company currently produces all of its VITEX Plasma Fractions and PLAS+SD
in its 92,000 square foot facility. In May 1998, the FDA approved the Company's
Establishment License Application for the manufacture of PLAS+SD at the
Company's manufacturing facility. The existing manufacturing facility has
sufficient capacity to meet the minimum purchase requirements for PLAS+SD under
its agreement with the Red Cross. In December 1998, the Company completed
construction of a $2.5 million multi-use manufacturing suite, within its
existing facility, to permit the production, subject to FDA approval, of
commercial quantities of fibrinogen and thrombin for production of VITEX Fibrin
Sealant. The manufacturing suite utilizes a design which provides operational
flexibility, and allows for multi-purpose production within the suite.
Validation of the new manufacturing suite is currently underway. The Company is
currently utilizing all of its existing fractionating plasma capacity. Due to
an industry-wide shortage of fractionation capacity, in conjunction with
solicitations from Bayer and others, the Company is planning to expand its
fractionation capacity by 15% in 1999 and is currently evaluating the
cost/benefit of further expansion in subsequent years. Through its
collaboration with Pall, the Company will cooperate in the development of red
blood cell concentrate viral inactivation systems and intends to contract with
third parties for the manufacture of these systems.

The Company's manufacturing processes are subject to extensive regulation by
the FDA, including the FDA's current Good Manufacturing Practice (cGMP)
requirements. Failure to comply with such requirements would materially impair
the Company's ability to maintain commercial-scale production of its plasma
fractions and PLAS+SD or achieve and maintain commercial-scale production of any
future products. If the Company is unable to achieve full scale production
capability for any product,

11


acceptance by the market of such product would be impaired and any such
impairment in market acceptance would have a material adverse effect on the
Company's business, financial condition and results of operations.

The Company purchases certain key components for the manufacture of its
products from a limited number of outside suppliers and intends to continue
purchasing components from outside suppliers for its future products. The
Company currently obtains from a single supplier the customized bags for the
packaging of its PLAS+SD product. However, the Company has entered into an
agreement with an additional supplier of these bags which provides that the
additional supplier will provide such bags if the existing supplier is unable to
do so. Further, while the Company has identified several sources for a key
component of one of its proposed wound care products, it is currently
negotiating an agreement with only a single supplier of this component.
Establishing or utilizing additional or replacement suppliers for any such
components, if required, may not be accomplished quickly and could involve
significant additional costs. Any failure by the Company to obtain any
components used to manufacture its products from alternative suppliers, if
required, could limit the Company's ability to manufacture its products and
could have a material adverse effect on the Company's business, financial
condition and results of operations. Moreover, the inclusion of components
manufactured by others could require the Company to seek approvals from
government regulatory authorities, which could result in delays in product
delivery. There can be no assurance that the Company would receive any such
regulatory approvals. Any such delay would have a material adverse effect on the
Company's business, financial condition, results of operations and cash flows.


Sales, Marketing and Distribution

As referred to in "Strategic Collaborations," the Company has entered into
agreements with Bayer, Red Cross, U.S. Surgical and Pall, for the development,
licensing and marketing of the Company's products and systems. In December 1998,
the Company established its own national sales force, consisting of a sales
director and ten regional sales representatives, to support the efforts of the
Red Cross by increasing product awareness and accelerating market penetration.
As part of these agreements, the Company is also collaborating with U.S.
Surgical and Pall for the development of certain of the Company's products and
systems. VITEX may seek to establish additional collaborations in other areas of
strategic focus.

In December 1997, and as subsequently amended effective October 1998, the
Company contracted with the Red Cross for the Red Cross to become the exclusive
distributor of the Company's PLAS+SD in North America. The Company and the Red
Cross have each committed to spend certain minimums for marketing PLAS+SD in
1999. Additionally, a joint marketing committee will coordinate all marketing
activities for PLAS+SD. The Company has entered into a distribution agreement
with U.S. Surgical pursuant to which the Company has granted U.S. Surgical the
exclusive worldwide rights to market and distribute its VITEX Fibrin Sealant,
subject to U.S. Surgical achieving stated minimum sales requirements for such
products. Under the terms of the Pall Agreements, Pall agreed to, among other
things, collaborate on the development and marketing of systems employing the
Company's viral inactivation technologies for RBCC. Under the Pall Agreements,
among other things, Pall receives exclusive worldwide distribution rights to any
systems incorporating any VITEX viral inactivation technology for red blood
cells.

The Company believes that market acceptance of the Company's products and
systems will depend, in part, on the Company's ability to provide acceptable
evidence of the safety, efficacy and cost-effectiveness of its products and
systems, as well as the ability of blood centers and hospitals to obtain
adequate reimbursement for such products. The Company believes that market
acceptance of its products and systems will also depend upon the extent to which
physicians, patients and health care payers perceive that the benefits of using
the Company's products and systems justify the additional costs and processing
requirements. There can be no assurance that the Company's products and systems
will gain any significant degree of market acceptance among blood centers,
physicians, patients and health care payers, even if clinical trials demonstrate
safety and efficacy and necessary regulatory approvals and health care
reimbursement approvals are obtained. There can be no assurance that the
Company's strategic collaborators will market the Company's products
successfully or that any third-party collaboration will be on terms favorable to
the Company. If a collaborator with the Company does not market a product
successfully, the Company's business would be materially adversely affected.
There can be no assurance that the Company's collaborators will be successful in
gaining market acceptance for any products that the Company may develop and a
failure to do so would result in a material adverse affect on the Company's
business, results of operations and financial condition.

Patents, Licenses and Proprietary Rights

The Company's success depends in part on its ability to maintain licensed
patent rights, obtain patents, protect trade secrets, operate without infringing
upon the proprietary rights of others and prevent others from infringing on the
proprietary rights of the Company. The Company's policy is to seek to protect
its proprietary position by, among other methods, filing United States and
foreign patent applications related to its proprietary technology, inventions
and improvements that are important to the development of its business. The
Company believes that the protection of its proprietary technologies may create
competitive barriers to entry into the viral inactivation market. The Company
intends to continue to pursue its patent filing strategy and to vigorously
defend its intellectual property position against infringement.

In connection with its spin-off from the NYBC, the Company became the licensee
of a substantial portfolio of patents and patent applications held by the NYBC.
The Company is a nonexclusive worldwide licensee under 12 issued United States
patents which expire at various times from 2000 to 2009, 28 issued foreign
counterpart patents and three pending foreign counterpart patent applications
held by the NYBC for use of the SD process in treating plasma derivatives. The
Company is a nonexclusive worldwide licensee under two issued United States
patents which expire in 2010 and 2014, four pending United States patent
applications, five issued foreign counterpart patents and 19 pending foreign
counterpart patent applications held by the NYBC for use of UVC technology in
treating plasma derivatives. The Company is the exclusive licensee for the U.S.,
Canada and Mexico and a non-exclusive licensee outside of the United States,
Canada, Mexico and Europe under 16 issued United States patents which expire at
various times from 2000 to 2014, four pending United States patent applications,
19 issued foreign counterpart patents and 14 pending foreign counterpart patent
applications held by the NYBC for use of the SD process and UVC technology in
treating transfusion plasma products. The Company is the exclusive worldwide
licensee under 10 issued United States patents which expire in 2010 and 2014,
five pending United States patent applications, five issued foreign counterpart
patents and 28 pending foreign counterpart patent applications held by the NYBC
for use of UVC technology in treating fibrin sealant/thrombin products and for
the manufacture and use of fibrin sealant, fibrinogen and thrombin and the
nonexclusive worldwide licensee under 12 issued United States patents which
expire at various times from 2000 to 2009, 28 issued foreign counterpart patents
and three pending foreign counterpart patent applications held by the NYBC for
use of the S/D process in treating fibrin sealant/thrombin products. Finally,
the Company is the exclusive worldwide licensee under six issued United States
patents which expire at various times from 2010 to 2015, eleven pending United
States patent applications, six issued foreign counterpart patents and 43
pending foreign counterpart patent applications held by the NYBC for use of
light and certain compounds in virally inactivating cellular products. The
rights referred to above are granted to the Company by five license agreements
between the Company and the NYBC. The NYBC has the right to terminate any of
these licenses if the Company breaches the respective license and fails to cure
such breach, fails to produce and market the relevant products within specified
time frames or fails to conform to government regulations in the production of
the relevant products. For exclusive licenses, the NYBC has the right to
terminate the license if certain minimum payments and/or minimum royalties are
not paid by the Company. If any of the licenses between the Company and the NYBC
were terminated it would have an adverse effect upon the Company's business,
results of operations and financial condition.

During the year ended January 2, 1999, the Company incurred royalty and
milestone related expenses amounting to $1,037,000 for use of technology
licensed by the NYBC.

In addition to being a licensee to patents and patent applications held by the
NYBC, the Company has three additional exclusive licenses for patents relating
to its red cell program, and is developing its own technologies and products and
pursuing patent protection for such technologies and products. The Company has
four pending United States patent application and is the co-owner of one issued
United States patent.

Proprietary rights relating to the Company's planned and potential products
will be protected from unauthorized use by third parties only to the extent that
they are covered by valid and enforceable patents or are effectively maintained
as trade secrets. There can be no assurance that any patents owned by, or
licensed to, the Company will afford protection against competitors or that any
pending patent applications now or hereafter filed by, or licensed, to the
Company will result in patents being issued. In addition, the laws of certain
foreign countries do not protect the Company's intellectual property rights to
the same extent as do the laws of the United States. The patent positions of
biopharmaceutical companies involve complex legal and factual questions and,
therefore, their enforceability cannot be predicted with certainty. There can be
no assurance that any of the Company's owned or licensed patents or patent
applications, if issued, will not be challenged, invalidated or circumvented, or
that the rights granted thereunder will provide proprietary protection or
competitive advantages to the Company against competitors with similar
technology. Furthermore, there can be no assurance that others will not
independently develop similar technologies or duplicate any technology developed
by the Company.

13


Because patent applications in the United States are maintained in secrecy
until patents issue, and since publication of discoveries in the scientific or
patent literature often lag behind actual discoveries, the Company cannot be
certain that it or its licensors were the first to make the inventions covered
by each of its issued, licensed or pending patent applications or that it or its
licensors were the first to file for protection of inventions set forth in such
patent applications. There can be no assurance that the Company's planned or
potential products will not be covered by third-party patents or other
intellectual property rights, in which case continued development and marketing
of such products would require a license under such patents or other
intellectual property rights. There can be no assurance that such required
licenses will be available to the Company on acceptable terms, if at all. If the
Company does not obtain such licenses, it could encounter delays in product
introductions while it attempts to design around such patents or could find that
the development, manufacture or sale of products requiring such licenses is
foreclosed.

The Company may rely, in certain circumstances, on trade secrets to protect
its technology. However, trade secrets are difficult to protect. The Company
seeks to protect its proprietary technology and processes, in part, by
confidentiality agreements with its employees and certain contractors. There can
be no assurance that these agreements will not be breached, that the Company
will have adequate remedies for any breach, or that the Company's trade secrets
will not otherwise become known or be independently discovered by competitors.


Competition

The Company's products and products under development will compete with
current approaches to enhance blood safety, as well as with future products
under development by others, including medical technology, biotechnology,
pharmaceutical and hospital supply companies, national and regional blood
centers, governmental organizations and agencies, academic institutions and
other agencies. The industries in which the Company competes are characterized
by rapid and significant technological changes. Accordingly, the Company's
success will depend in part on its ability to respond quickly to medical and
technological changes through the development and introduction of new products.
Many companies and organizations that may be competitors or potential
competitors of the Company have substantially greater financial and other
resources than the Company and may have greater experience in pre-clinical
studies, clinical trials and other regulatory approval procedures. In addition,
other technologies or products may be developed that have an entirely different
approach or means of accomplishing the intended purposes of the Company's
products, or that might render the Company's technology and products obsolete.
Furthermore, there can be no assurance that the Company's competitors will not
obtain patent protection or other intellectual property rights that would limit
the Company's ability to use the Company's technology or commercialize products
that may be developed.

VITEX Plasma Fractions face competition from other large plasma fractionators.
Additional competition in the market for plasma derivatives may come from
producers of recombinant blood products. Competition in this area may have a
material adverse effect on the Company's business, financial condition and
results of operations.

Competition with PLAS+SD and the Company's products under development may come
from alternative approaches to the problem of improving the safety of blood and
blood products and from alternative viral inactivation technologies. The
alternative approaches to achieving safer blood component products include donor
retesting, apheresis blood collection systems, the use of blood substitutes,
blood salvage systems, blood cell stimulants, leukocyte filters and reduction
systems and improved blood testing. All of these approaches are currently
available, and each has gained some degree of market acceptance.

In the area of viral inactivation of blood and blood components, several
companies are developing technologies which are, or in the future may be, the
basis for products that will directly compete with or reduce the market
opportunity for PLAS+SD and the Company's viral inactivation products which are
under development. In the plasma market, treatment with methylene blue is used
commercially in Europe for pathogen inactivation. Because the Company's SD
process involves pooling plasma, there may be an increased risk of transmission
of pathogens not inactivated by the process, as compared with processes, such as
treatment with methylene blue, which do not require pooling. In addition to
methylene blue, other viral inactivation methods which may compete with the
Company's Solvent/Detergent (SD), Ultraviolet C Light (UVC), and Light Activated
Compound (LAC) technologies include patented viral inactivation compounds,
including psoralens, developed by Cerus Corporation. Additionally, ozone
sterinetics technology under development may compete with the Company's viral
inactivation technology. The Company believes that the primary competitive
factors in the market for viral inactivation systems will include the breadth
and effectiveness of viral inactivation processes, ease of use, the scope and
enforceability of patent or other proprietary rights,

14


product price, product supply and marketing and sales capability. In addition,
the length of time required for products to be developed and to receive
regulatory and, in some cases, reimbursement approval is an important
competitive factor. The Company believes it competes favorably with respect to
these factors, although there can be no assurance that it will be able to
continue to do so. Any failure by the Company to compete effectively with these
alternative products and technologies would have a material adverse effect on
the Company's business, financial condition, results of operations and cash
flows.

The Company's wound care products will compete with existing wound care
techniques, such as sutures and synthetic glues, which do not carry the risk of
viral contamination. The Company may face competition from many other companies
seeking to develop and market fibrin sealants. The Company believes several
other companies are developing competitive wound care products, including
synthetic glues and other alternatives to sutures. There can be no assurance
that any of these alternative viral inactivation systems or wound care products
will not achieve widespread acceptance. For the Company's products to gain
market acceptance, the Company may need to demonstrate that its products are
superior in performance, safer or more cost-effective than other existing or
future technologies or products.


Government Regulation

The Company and its products are comprehensively regulated by the FDA and, in
some instances, by state and local governments, and by foreign regulatory
authorities. The FDA regulates drugs, medical devices and biologics under the
Federal Food, Drug and Cosmetic Act and other laws, including, in the case of
biologics, the Public Health Service Act. These laws and implementing
regulations govern, among other things, the development, testing, manufacturing,
record keeping, storage, labeling, advertising, promotion and pre-market
approval of such products.

The PLA for the Company's VITEX Plasma Fractions was approved initially by the
FDA in 1970 and amended from time to time thereafter. The first of the Company's
virally inactivated products, PLAS+SD, received marketing approval by the FDA on
May 6, 1998. The Company believes that its VITEX Fibrin Sealant, like VITEX
Plasma Fractions and PLAS+SD, will be regulated by the FDA as a biologic, while
its RBCC system may be regulated as a medical device. However, despite the
Company's expectations of how a given product will be regulated, it is possible
that the FDA will decide to regulate any one or more of the Company's products
as biologics, as medical devices, as "combination products," including drugs or
biologics and one or more medical devices, or as drugs or biologics with one or
more medical devices requiring separate approval or clearance. Whether the FDA
regulates the Company's products as biologics or as one or more of the other
alternatives, it is likely that the FDA's Center for Biologics Evaluation and
Review will be principally responsible for regulating the Company's products.

Before a new drug may be marketed in the United States, the FDA must approve
an NDA for the product. Before a biologic may be marketed in the United States,
the FDA must approve either a Biologics License Application (BLA) covering both
the product and the facility or a PLA for the product and an Establishment
License Application (ELA) for the facility at which the product is manufactured.
Before a medical device may be marketed in the United States, the FDA must clear
a pre-market notification (a 510(k)) or approve a pre-market application (PMA)
for the product. Before a combination product may be marketed in the United
States, it must have an approved NDA, BLA (or PLA/ELA) or PMA, depending on
which statutory authority the FDA elects to use.

Despite the multiplicity of statutory and regulatory possibilities, the steps
required before approval are essentially the same whether the product is
ultimately regulated as a drug, a biologic, a medical device, a combination
product or some combination thereof. The steps required before a drug, biologic
or medical device may be approved for marketing in the United States pursuant to
an NDA, BLA (or PLA/ELA) or PMA, respectively, generally include: (i) pre-
clinical laboratory and animal tests; (ii) submission to the FDA of an
Investigational New Drug Exemption (IND), for drugs or biologics, or an
investigational device exemption (IDE), for medical devices, for clinical
trials, which must become effective before human clinical trials may begin;
(iii) appropriate tests to show the product's safety; (iv) adequate and well-
controlled human clinical trials to establish the product's efficacy for its
intended indications; (v) submission to the FDA of an NDA, BLA (or PLA/ELA) or
PMA, as appropriate and (vi) FDA review of the NDA, BLA (or PLA/ELA) or PMA in
order to determine, among other things, whether the product is safe and
effective for its intended uses. In addition, the FDA inspects the facilities at
which the product is manufactured and will not approve the product unless
compliance with cGMP requirements is satisfactory. The steps required before a
medical device may be cleared for marketing in the United States pursuant to a
510(k) are generally the same, except that instead of conducting tests to
demonstrate safety and efficacy, data, including clinical data if necessary,
must be obtained to

15


show that the product is substantially equivalent to a legally marketed device,
and the FDA must make a determination of substantial equivalence rather than a
determination that the product is safe and effective.

The Company believes that, in deciding whether a viral inactivation system is
safe and effective, the FDA is likely to take into account whether it adversely
affects the therapeutic efficacy of blood components as compared to the
therapeutic efficacy of blood components not treated with the system, and that
the FDA will evaluate the system's safety and other risks against the benefits
of using the system in a blood supply that has become safer in recent years.

There can be no assurance that the means employed by the Company of
demonstrating safety and efficacy will ultimately be acceptable to the FDA.
Moreover, even if the FDA considers these means of demonstrating safety and
efficacy to be acceptable in principle, there can be no assurance that the FDA
will find the data submitted sufficient to demonstrate safety and efficacy.

Even if regulatory approval or clearance is granted, it could include
significant limitations on the indicated use for which a product could be
marketed. The testing and approval/clearance process requires substantial time,
effort and financial resources, and is generally lengthy, expensive and
uncertain. The approval process is affected by a number of factors, including
the availability of alternative treatments and the risks and benefits
demonstrated in clinical trials. Additional animal studies or clinical trials
may be requested during the FDA review period and may delay marketing approval.
After FDA approval for the initial indications, further clinical trials may be
necessary to obtain approval for the use of the product for additional
indications. The FDA may also require post-marketing testing to monitor for
adverse effects which can involve significant expense. Later discovery of
previously unknown problems with a product may result in labeling changes and
other restrictions on the product, including withdrawal of the product from the
market. In addition, the policies of the FDA may change, and additional
regulations may be promulgated which could prevent or delay regulatory approval
of the Company's planned products. There can be no assurance that any approval
or clearance will be granted on a timely basis, if at all. Any failure to obtain
or delay in obtaining such approvals or clearances, and any significant
limitation on their indicated uses, could have a material adverse effect on the
Company's business, financial condition and results of operations.

A drug, biologic or medical device, its manufacturer, and the holder of the
NDA, BLA (or PLA/ELA), PMA or 510(k) for a product are subject to comprehensive
regulatory oversight, both before and after approval or clearance is obtained.
Violations of regulatory requirements at any stage, including during the
preclinical and clinical trial process, during the approval/clearance process or
after the product is approved/cleared for marketing, could result in various
adverse consequences, including the FDA's requiring that a clinical trial be
suspended or halted, the FDA's delay in approving/clearing or refusing to
approve/clear a product, withdrawal of an approved/cleared product from the
market and the imposition of criminal penalties. For example, the holder of an
NDA, BLA (or PLA/ELA), PMA or 510(k) is required to report certain adverse
reactions to the FDA, and must comply with certain requirements concerning
advertising and promotional labeling for the product. Also, quality control and
manufacturing procedures must continue to conform to cGMP regulations after
approval or clearance, and the FDA periodically inspects manufacturing
facilities to assess compliance with cGMP. In particular, until the Company
achieves commercial production levels of its PLAS+SD product, the test results
for each lot of this product will be subject to FDA review prior to release for
its intended use. Accordingly, manufacturers must continue to expend time,
monies and efforts on regulatory compliance, including cGMP compliance. In
addition, new government requirements may be established that could delay or
prevent regulatory approval or clearance of the Company's products under
development or otherwise alter the applicable law. There can be no assurance
that the FDA will determine that the facilities and manufacturing procedures of
the Company or any other third-party manufacturer of the Company's planned
products will conform to cGMP requirements.

In addition to the regulatory requirements applicable to the Company and its
products, there are also regulatory requirements applicable to the Company's
prospective customers, which are primarily entities that ship blood and blood
products in interstate commerce. Such entities are regulated by the FDA pursuant
to the Food, Drug and Cosmetic Act and the Public Health Service Act and
implementing regulations. Blood centers and others that ship blood and blood
products interstate will likely be required to obtain approved license
supplements from the FDA before shipping products processed with the Company's
viral inactivation systems. This requirement and/or FDA delays in approving such
supplements may deter some blood centers from using the Company's products, and
blood centers that do submit supplements may face disapproval or delays in
approval that could provide further disincentives to use of the systems. The
regulatory impact on potential customers could have a material adverse effect on
the Company's business, financial condition and results of operations.

The Company is subject to federal, state and local laws, rules, regulations
and policies governing the use, generation, manufacture, storage, air emission,
effluent discharge, handling and disposal of certain materials, biological
specimens and wastes. As production volume of PLAS+SD increase, Company may be
required to obtain a permit amendment from regulatory

16


authorities to increase the associated volume of permitted discharge. Although
the Company has submitted an application to obtain this permit amendment and is
actively pursuing it, there can be no assurance that such permit amendment will
be obtained in a timely manner, if at all. There can be no assurance that the
Company will not be required to incur significant costs to comply with
environmental and health and safety regulations in the future. The Company's
research and development involves the controlled use of hazardous materials,
including certain hazardous chemicals, viruses and radioactive materials.
Although the Company believes that its safety procedures for handling and
disposing of such materials comply with the standard prescribed by state and
federal regulations, the risk of accidental contamination or injury from these
materials cannot be eliminated. In the event of such an accident, the Company
could be held liable for any damages that result and any such liability could
exceed the resources of the Company.


Health Care Reimbursement

The Company's ability to successfully commercialize its products is dependent
in part on the extent to which appropriate levels of reimbursement for the
Company's products and related treatments are obtained from government
authorities, private health insurers and other organizations, such as managed
care organizations (MCOs). Failure by doctors, hospitals and other users of the
Company's products or systems to obtain appropriate levels of product cost
reimbursement could adversely affect the Company's ability to sell its products
and systems. There are widespread public and private efforts to control health
care costs, and it is unlikely that these efforts will be abandoned in the near
future. Third-party payers are increasingly challenging the pricing of medical
products and services. The trend toward managed care health in the U.S., the
growth of MCOs and legislative proposals to reform health care and government
insurance programs could significantly influence the purchase of medical
products and services, resulting in lower prices and reduced demand for the
Company's products. Such cost containment measures and health care reform could
affect the Company's ability to sell its products, which the Company expects
will be priced at a premium to corresponding widely used blood products that are
not virally inactivated, and may have a material adverse effect on the Company.
Significant uncertainty exists about the reimbursement status of newly approved
medical products and services. There can be no assurance that reimbursement in
the United States or foreign countries will be available for any of the
Company's products, that any reimbursement granted will be maintained or that
limits on reimbursement available from third-party payers will not reduce the
demand for, or negatively affect the price of, the Company's products. The
unavailability or inadequacy of third-party reimbursement for the Company's
products would have a material adverse effect on the Company's business,
financial condition, results of operations and cash flows.


Research and Development

The Company believes that continued and timely development of new products and
enhancements to existing products are necessary to maintain its competitive
position. To this end, the Company relies on a combination of its own internal
expertise and strategic alliances with its collaborators and other companies to
enhance its research and development efforts. In addition to new product
candidates generated by internal research and development activities, the
Company actively monitors external research and development programs in search
of complementary and advanced technology for potential acquisition or license
arrangement.

Research and development expense, which includes technology license fees paid
to third parties, amounted to $7.5 million, $5.9 million and $4.4 million for
the years ended January 2, 1999 and December 31, 1997 and 1996, respectively.
Such amounts are net of collaborator reimbursement in the amount of $2.3
million, $1.2 million and $1 million for the years ended January 2, 1999 and
December 31, 1997 and 1996, respectively.

The field of transfusion medicine and therapeutic use of blood products is
characterized by rapid technological change. Product development involves a
high degree of risk, and there can be no assurance that the Company's product
development efforts will result in any commercial success.

17


Environmental Regulation; Use of Hazardous Substances

The Company is subject to federal, state and local laws, rules, regulations
and policies governing the use, generation, manufacture, storage, air emission,
effluent discharge, handling and disposal of certain materials, biological
specimens, and wastes. The Company has made, and will continue to make, the
necessary expenditures for environmental compliance and protection.
Expenditures for compliance with environmental laws have not had, and are not
expected to have, a material effect on the Company's financial position,
results of operations or cash flows. The Company's research and development
activities involve the controlled use of hazardous materials. Although the
Company believes that its safety procedures for handling and disposing of such
materials comply with the standards proscribed by state and federal regulations,
the risk of accidental contamination or injury from these materials cannot be
eliminated. In the event of such and accident, the Company could be held liable
for any damages that result and such liability could exceed the resources of the
Company.


Customers

The Company's revenues are derived from the sale of plasma fractions,
principally to Bayer, and transfusion plasma to the Red Cross. During the year
ended January 2, 1999, revenue from sales to Bayer and the Red Cross comprised
43.4% and 48.4%, respectively of the Company's total revenues during such
period.


Employees

As of January 2, 1999, the Company had 265 employees of which 42 were engaged
in research and development, 189 were engaged in manufacturing, 14 were engaged
in sales and marketing and 20 were engaged in other activities. The Company's
competitive position in the blood products industry depends, in part, on its
continued ability to recruit and retain qualified scientists, managerial and
technical employees who are in considerable demand. There can be no assurance
that the Company will be able to continue to attract and retain qualified
personnel in sufficient numbers to meet its needs. None of the Company's
employees is represented by a labor union and the Company has never experienced
a work stoppage, slowdown, or strike. The Company considers its employee
relations to be good.


Item 2. PROPERTIES

The Company's primary executive offices and manufacturing facility are
contained within a 92,000 square foot Company-owned building in Melville, New
York. The Company has made, and is continuing to make improvements to this
facility to accommodate VITEX Plasma Fractions and PLAS+SD production
requirements, and to produce sufficient quantities of VITEX Fibrin Sealant to
meet regulatory filing requirements and to support initial product demand. The
Company currently leases 12,000 square feet of space in New York, New York to
accommodate its research and development activities, and 7,500 square feet of
office space in Melville, New York, for certain of the Company's administrative
functions.

The Company believes that its current facilities, combined with anticipated
additions and improvements currently under construction, are adequate for all
present and foreseeable future uses.


Item 3. LEGAL PROCEEDINGS

The Company is a party to certain legal proceedings which are discussed
below. While it is impossible to predict accurately or to determine the eventual
outcome of these matters, the Company believes that the outcome of these
proceedings will not have a material adverse effect on the annual financial
statements of the Company.

The Company is aware that in the course of ongoing litigation between the
NYBC and a third party, the third party has asserted claims against NYBC based
on breach of a contract that was executed in 1988 by those parties and rights
under which were assigned to the Company in 1995. The third party has claimed
that it is entitled to payments from the NYBC based on improvements in albumin
throughput yields attributable to certain filtration technology licensed to the
NYBC by the third party. The Company understands that the NYBC believes it has
meritorious defenses against this third party's claims and, in any event, as
part of the assignment of NYBC's rights under the disputed contract by the NYBC
to the Company, the Company assumed no

18


responsibility for pre-existing contract liabilities. However, there can be no
assurance that the third party will not assert claims against the Company under
that contract which are similar in nature to the claims being asserted against
the NYBC. No such claims have been asserted to date. The Company believes that
it would have meritorious defenses against any such claims.

On March 23, 1998, the Company received a Civil Investigative Demand ("CID")
from the Antitrust Division of the U.S. Department of Justice (the "Justice
Department") as part of the Justice Department's investigation into possible
antitrust violations in the sale, marketing and distribution of blood products.
A CID is a formal request for information and a customary initial step of any
Justice Department investigation. The Justice Department is permitted to issue
a CID to anyone whom the Justice Department believes may have information
relevant to an investigation. Therefore, the receipt of a CID does not mean
that the recipient is the target of an investigation, nor does it presuppose
that there is a probable cause to believe that a violation of the antitrust laws
has occurred or that any formal complaint ultimately will be filed. The Company
believes that the primary focus of the CID relates to the Company's PLAS+SD
product and to the Supply, Manufacturing and Distribution Collaboration
Agreement between VITEX and the American National Red Cross. Following the
Company's response to the CID there has been no further activity with respect to
this matter.

On August 27, 1998, the Appellate Division of the Supreme Court of New York
awarded the Company a summary judgement against its insurance carrier, reversing
a lower court decision which denied the Company's previous claim for recovery of
costs incurred in 1996 as a result of a plasma processing loss. The Company had
recorded a special charge in 1996 to recognize reimbursement due to Bayer
Corporation for the plasma loss ($4.1 million) and to write off processing costs
($1.0 million). The Company has filed a claim with the insurer to recover these
and related costs. On October 27, 1998, the insurance carrier filed a motion to
appeal the decision of the Appellate Court. Such appeal was subsequently
rejected. The insurance carrier has since stated its intention to take the
appeal to a higher court. The ultimate outcome of this matter can not be
determined at the present time.


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

No matters were submitted to a vote of the Company's security holders
during the last quarter of its fiscal year ended January 2, 1999.

As of March 26, 1999, the Company had approximately 40 shareholders of record.

The Company has not paid any dividends on its common stock to date. The
Company intends to retain future earnings for use in the development of its
business and does not anticipate paying dividends in the foreseeable future.
The payment of any dividends will be at the discretion of the Company's Board of
Directors and will depend on, among other things, future earnings, business
outlook, capital requirements, contractual restrictions, and the general health
of the Company. The ability of the Company to pay dividends is currently
restricted by covenants contained in its Credit Agreement with its bank.

Under the Company's 1998 Equity Incentive and 1998 Director Stock Option
Plans, during the year ended January 2, 1999, the Company granted options to
purchase 642,000 shares of the Company's Common Stock, exercisable at a weighted
average price of $10.09 per share. At January 2, 1999, there were 1,703,000
options outstanding, of which 484,000 were exercisable. The shares of the
Company's common stock issuable upon exercise of options granted under the 1998
Equity Incentive Plan and 1998 Director Stock Option Plan have been registered
pursuant to registration statements on Form S-8.

(b) In its initial public offering, including a second overallotment, the
Company sold an aggregate of 3,325,000 shares, with an aggregate offering price
to the public of $39,900,000. After expenses, the Company's net proceeds from
the offering were $35,868,000. The Company has utilized these proceeds to: (i)
fund capital investments, primarily for improvements and expansion of its
manufacturing facility ($4,100,000), (ii) fund operations ($3,500,000),
including research and development costs of approximately $2,000,000, and (iii)
for the repayment of debt ($400,000). The Company will continue to use the
remaining net proceeds to fund costs associated with the marketing and
distribution of PLAS+SD, clinical trials, research and development and capital
investments, including the expansion of the manufacturing facility and other
general corporate purposes. Unused proceeds of the offering are invested in
money market funds with portfolios of investment grade corporate and U.S.
government securities.

(1) During 1996, the Company entered into an exclusive distribution agreement
with U.S. Surgical regarding VITEX Fibrin Sealant for a period of 15 years.
The Company was paid a non-refundable fee of $3 million for such
exclusivity (see note 11 to the financial statements). The Company also
agreed to pay damages of $4.1 million to compensate Bayer for its loss of
plasma caused by an equipment malfunction which occurred while the Company
was processing plasma for Bayer (see note 11 to the financial statements).

(2) During the year ended January 2, 1999, the Company completed an IPO of
3,325,000 shares of the Company's common stock at a price of $12.00 per
share, raising net proceeds of $35.9 million (see note 8 to financial
statements). In conjunction with the collaboration agreement between the
Company and Pall, Pall acquired $9 million of the Company's common stock in
two private placements, the second of which closed contemporaneously with,
and at the same price terms and conditions as the IPO. The Company recorded
a charge to operations of $2.2 million representing the difference between
the purchase price paid by Pall and the estimated fair value of the common
stock on the date of purchase (see note 11 to the financial statements).

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

Overview

VITEX is a leading developer of a broad portfolio of blood products and
systems which use its proprietary viral inactivation technologies. The Company's
technologies are intended to address the risks of viral contamination in blood
products, including plasma, plasma derivatives, red blood cells and platelets.
Viral inactivation processes have the potential to eliminate viruses that are
enveloped by lipid membranes such as hepatitis B virus (HBV), hepatitis C virus
(HCV) and HIV, the virus that causes AIDS, and non-enveloped viruses such as
hepatitis A virus (HAV) and parvovirus and other known and unknown pathogens.

The Company currently manufactures two human therapeutic products:

. PLAS+SD. The Company has entered into a collaboration agreement with the
American National Red Cross (Red Cross), whereby the Red Cross is the exclusive
distributor of the Company's PLAS+SD in North America. PLAS+SD, the first of the
Company's virally inactivated products, received marketing clearance from the
FDA on May 6, 1998. Commercial scale production and sale of PLAS+SD, a pooled
transfusion plasma which utilizes the Company's solvent/detergent (SD) viral
inactivation technology to inactivate lipid enveloped viruses, began in June
1998. PLAS+SD was the first, and is the only FDA approved, virally inactivated
blood component available for use in the United States.

. VITEX Plasma Fractions. The Company supplies VITEX Plasma Fractions,
primarily to Bayer Corporation (Bayer), under a collaboration arrangement. The
Company utilizes a combination of fractionation procedures and chromatographic
techniques to separate and purify the protein components of plasma. The plasma
fractions are further processed by the Company's customers into virally
inactivated plasma derivatives for use in FDA-approved therapeutic applications.

The Company's other virally inactivated blood products are all under
development and include:

. Universal PLAS+SD. Universal PLAS+SD is a product which is intended to
provide the same benefits as PLAS+SD without the need for matching donor and
recipient blood types. Under the Company's collaboration agreement with the Red
Cross, the Red Cross has a right of first offer to distribute this product if it
is approved by the FDA.

. Universal PLAS+SD II. Universal PLAS+SD II is intended to improve upon
Universal PLAS+SD by adding a second method of viral inactivation to inactivate
both enveloped and non-enveloped viruses.

. VITEX Fibrin Sealant. VITEX Fibrin Sealant, which is currently in Phase III
clinical trials, is designed for use during surgical procedures to augment or
replace sutures or staples for wound closure. The Company has collaborated with
United States Surgical Corporation (U.S. Surgical) to develop and distribute
this product.

. VITEX RBCC Systems. The Company has entered into strategic collaboration
agreements with Pall Corporation (Pall) for the development and marketing of
VITEX RBCC Systems which employ the Company's technologies to broadly inactivate
viruses and other pathogens in red blood cell concentrates.

On August 10, 1998, the Company changed from a calendar year to a 52-53 week
fiscal year ending on the Saturday closest to December 31, beginning with the
fiscal year ending January 2, 1999.

The Company reported net income of $0.5 million and $1.0 million, during the
third and fourth quarters, respectively, of the year ended January 2, 1999, and
a net loss of $6.4 million for the year. The Company's accumulated deficit at
January 2, 1999 was $33.1 million. Operating results will vary from period to
period and, net income for periods during the year ended January 2, 1999 may not
necessarily be indicative of results that may be expected in future periods.

Results of Operations

Year Ended January 2, 1999 as Compared to Year Ended December 31, 1997

Revenue

Revenue increased $18 million during the year ended January 2, 1999 to $33.8
million compared to $15.8 million during fiscal1997. The increase was primarily
due to sales of PLAS+SD which received marketing clearance from the FDA on May
6, 1998. Commercial scale production and sale of PLAS+SD began in June 1998.
Also contributing to the increase in revenue was an increase in sales of plasma
fractions as a result of higher processing volume, partially offset by a
decrease in unit pricing in accordance with the Company's processing agreement
with Bayer. The processing agreement also specifies a price increase, effective
January 1, 1999, in an amount equal to the increase in the consumer price index.

Cost of Sales

Cost of sales increased $7.6 million during the year ended January 2, 1999 to
$23.9 million, compared to $16.3 million during fiscal 1997. The increase was
primarily due to processing and start-up costs related to the production of
PLAS+SD.

Product gross margin was approximately 29.3% for the year ended January 2,
1999. This was a significant improvement from fiscal 1997, which did not
contain revenue from the sale of PLAS+SD. As a result of manufacturing cost
reductions, product yield improvements and higher pricing negotiated under the
amended collaboration agreement with the Red Cross agreement, product gross
margin was approximately 40.8% during the thirteen weeks ended January 2, 1999.
In fiscal 1999, product gross margins are expected to be similar to those
achieved during the last quarter of the year.

Research and Development

Research and development costs increased $1.6 million during the year ended
January 2, 1999 to $7.5 million, compared to $5.9 million during fiscal 1997.
The increase in research and development costs is primarily due to the expanded
activities in the Company's red blood cell program, advanced stage development
spending for its fibrin sealant program and additional new product research
activities. Further increases in research and development expenditures are
expected to continue during fiscal 1999. Research and development costs are
recorded net of collaborator reimbursement which amounted to $2.3 and $1.2
million for the years ended January 2, 1999 and December 31, 1997, respectively.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased $2.6 million during
the year ended January 2, 1999 to $7 million, compared to $4.4 million during
fiscal 1997. The increase is principally due to administrative costs associated
with the hiring of new personnel, including the national sales force which was
hired in December 1998, marketing costs associated with PLAS+SD, legal expenses
associated with collaborator agreements and a response to a Civil Investigative
Demand from the U.S. Department of Justice. The Company and the Red Cross have
each committed to spend certain minimum amounts for marketing PLAS+SD during the
two year period ending September 30, 2000. The Company's spending commitment is
expected to be satisfied, to a large extent, by the cost of its sales force. The
Company expects that its selling, general and administrative expenses will
increase during fiscal 1999 as a result of this increased level of sales and
marketing commitment.

Charge Related to Research Collaboration

During the year ended January 2, 1999, the Company recorded a one-time charge
of $2.2 million in connection with its research collaboration with Pall
Corporation. The charge occurred in connection with an equity investment in the
Company made by Pall under the collaboration agreement and reflects the
difference between the amount paid for the shares issued to Pall and the fair
market value of the common stock at that date.

Net Interest Expense

During the years ended January 2, 1999 and December 31, 1997, the Company
incurred net interest expense of $0.3 million and $1 million, respectively,
reflecting the levels of debt outstanding during such periods, offset by
interest earned on cash balances, including the proceeds from the Company's
initial public offering. During the quarter ended January 2, 1999, the

23


Company recorded a non-cash gain of $0.6 million relating to the discounting of
the $3 million non-interest bearing advance from the Red Cross. The advance was
discounted upon finalization of the repayment terms contained in the amended Red
Cross Agreement.


Year Ended December 31, 1997 as Compared to Year Ended December 31, 1996

Total revenues decreased from $17.9 million in 1996 to $15.8 million in 1997,
a decrease of $2.1 million. This decrease was due principally to the receipt by
the Company in 1996 of a one-time licensing fee of $3.0 million which was
partially offset by increases in processing and product revenues of $0.9 million
in 1997. The increase in processing and product revenues reflects an increase in
processing volume partially offset by a decrease in unit pricing under the
Company's processing agreement with Bayer.

Cost of Sales

Cost of sales increased from $10.6 million in 1996 to $16.3 million in 1997,
an increase of $5.7 million. Cost of sales includes costs related to processing
fractionated products and those costs formerly classified as facility costs
which amounted to $1.4 and $6 million in 1996 and 1997, respectively.
Fractionation production gross margin, excluding facility costs relating to
PLAS+SD ramp-up costs, decreased from 38.7% in 1996 to 34.7% in 1997. The gross
margin in 1996 reflects unrecovered processing costs of $1.0 million incurred by
the Company in processing Bayer's plasma during an equipment malfunction.
Exclusive of this $1.0 million charge, the gross margin was 45.4% in 1996. The
decrease in gross margin in 1997 was due to a decrease in unit pricing under the
Processing Agreement with Bayer, increased maintenance costs related to
scheduled servicing of the Company's plasma fractionation assets and increased
materials costs.

Research and Development

Research and development costs increased from $4.4 million in 1996 to $5.9
million in 1997, an increase of $1.5 million. The increase is due principally to
the expanded activities in the Company's VITEX RBCC programs, expanded clinical
trials for VITEX Fibrin Sealant and additional development activities.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased from $2.5 million in
1996 to $4.4 million in 1997, an increase of $1.9 million. The increase
represents costs associated with the initiation of market research activities,
education and other pre-marketing activities in connection with the anticipated
commercial introduction of PLAS+SD. In addition, during 1997, the Company
incurred $0.7 million of non-recurring severance costs and $0.2 million of debt
refinancing costs.

Net Interest Expense

Net interest expense increased from $0.5 million in 1996 to $1 million in 1997
due to additional debt financing.


Liquidity and Capital Resources

The Company has historically financed its operations primarily through sales
of common stock, issuance of long-term debt and capital lease financing
arrangements. In addition, the Company generates cash from the sale of VITEX
Plasma Fractions which are sold primarily to Bayer, and PLAS+SD which is sold to
the Red Cross. The Company also receives research and development funding under
a collaboration agreement from U.S. Surgical for the direct costs of the fibrin
sealant program clinical and regulatory activities and from Pall Corporation
under its red blood cells research collaboration agreement.

On June 15, 1998, the Company completed an initial public offering ("IPO") of
3,000,000 shares of the Company's common stock, raising net proceeds of
approximately $32.2 million. On July 10, 1998, the underwriters of the
Company's IPO partially exercised their over-allotment option for an additional
325,000 shares, raising net proceeds of $3.6 million. In conjunction with the
collaboration agreement between the Company and Pall, Pall purchased $9 million
of the Company's common stock in two private placements which occurred during
1998. The first placement, which occurred in February 1998,

24


amounted to $4 million, and the second amounted to $5 million and closed
contemporaneously with, and at the same price, terms and conditions as the IPO.

At January 2, 1999, the Company had working capital of $33.1 million,
including cash and cash equivalents of $35.3 million. At December 31, 1997,
there was a working capital deficit of $2.8 million, including cash and cash
equivalents of $5.3 million. The increase in cash balances was primarily due
to the Company's financing activities, which provided cash of $41.9 million. The
primary objectives for the Company's investment of cash balances are safety of
principal and liquidity. Available cash balances are invested in money market
funds with portfolios of investment grade corporate and U.S. government
securities.

In order to maintain its exclusive marketing and distribution rights for
PLAS+SD, the Red Cross is required to purchase stated minimum quantities
amounting to approximately $50 million during the two year period ending
September 30, 2000. The Company and the Red Cross have each committed to spend
minimum amounts for marketing PLAS+SD during the two-year period ending
September 30, 2000. The Company's spending commitment is expected to be largely
satisfied by the cost of its sales force established in December 1998 to support
the Red Cross in promoting product awareness and accelerating market
penetration.

U.S. Surgical has agreed to fund all future direct clinical and regulatory
costs associated with the development and regulatory approval of VITEX Fibrin
Sealant. In addition, U.S. Surgical has agreed to pay a portion of agreed upon
research and development costs for improvements and enhancements to VITEX Fibrin
Sealant.

Under its collaboration with Pall, the Company and Pall have agreed to equally
share research, development, clinical and regulatory costs. Profits will be
shared equally after each party is reimbursed for its cost of goods. The
agreements provide that Pall will purchase up to $17.0 million of VITEX Common
Stock in installments tied to the achievement of specified development
milestones. These equity investments will be made at the prevailing market
price.

Under the Company's license agreements with the NYBC, the Company is required
to pay aggregate minimum royalties of $1,500,000 in 1999, $2,200,000 in 2000,
$2,400,000 in 2001 and $2,800,000 in each year thereafter in order to maintain
its exclusive licenses. The Company is also required to make specified payments
to the NYBC to maintain its exclusive licenses if certain research and
development milestones are not met by the Company.

In December 1997, the Company entered into a credit agreement with a bank
providing for a term loan in the principal amount of $10.8 million. The proceeds
under this term loan were used to repay the outstanding balance of existing term
loans aggregating $10.5 million. This loan bears interest at the Company's
option at LIBOR plus 2.75% to 1.75%, or the base rate of the bank, as defined,
plus margins of up to 0.5% as determined based on defined earnings ratios. As of
January 2, 1999, the Company was using one-month LIBOR (5.1%) plus 2.75%. Under
this loan, interest is payable monthly and the principal balance is payable in
16 equal consecutive quarterly installments of $0.7 million commencing March 31,
1998 and continuing until maturity on December 31, 2001. The credit agreement
contains default provisions, including financial covenants which provide
restrictions on capital investments, the payment of cash dividends and, among
other things, requires the Company to maintain minimum cash balances of $2.0
million and leverage and coverage ratios as defined. The Company is in
compliance with such covenants.

Under the Company's capital and operating leases, annual minimum rental
payments and related interest expense over the next five years is $7.6 million.

Prior to 1995, the Red Cross made to the Company's predecessor, a total of
$3.0 million of non-interest bearing, unsecured advances to be used to fund
improvements to the manufacturing facility. In conjunction with the amended Red
Cross Agreement, the repayment schedule was modified to reflect repayment of 30%
of the loan balance on the second anniversary date of the approval of the
PLAS+SD PLA and 15% of the balance on each of the following two years, with the
balance of the loan payable on the fifth anniversary of the PLAS+SD PLA. During
the quarter ended January 2, 1999, the Company recorded a non-cash gain of $0.6
million to discount the advance to its net present value.

At January 2, 1999, the Company had net operating loss carryforwards for
federal and state income tax reporting purposes of approximately $28 million and
has available research and development credit carryforwards for federal income
tax reporting purposes of approximately $0.5 million, which are available to
offset future taxable income, if any. These carryforwards expire beginning in
2010. The Company's ability to use such net operating loss and research and
development credit carryforwards is

25


limited by change in control provisions under Section 382 of the Internal
Revenue Code. See note 10 to the Company's Financial Statements.

Although the Company's cash requirements will fluctuate based on the timing
and extent of the above factors, management believes that cash generated from
operations, together with the liquidity provided by existing cash balances, will
be sufficient to meet the Company's working capital requirements through January
1, 2000.


Risk Factors that May Affect Future Results

Dependence on New Products and Systems in Development Stage

The success of the Company's business will depend on the development and
commercialization of its virally inactivated products and viral inactivation
systems. On May 6, 1998, the Company received FDA approval to market its pooled
virally inactivated transfusion plasma product, PLAS+SD. The Company's other
virally inactivated blood products are under development and have not been
approved by the FDA for marketing in the United States or by regulatory
authorities in other countries. There can be no assurance that these products
and systems will be successfully developed and, if developed, that they will
generate revenues and profits. Successful commercialization of the Company's
products and systems under development depends, in significant part, on the
Company's ability to: (i) complete their development in a timely fashion; (ii)
obtain and maintain patents or other proprietary protections; (iii) obtain
required regulatory approvals; (iv) implement efficient, commercial-scale
manufacturing processes; (v) gain early entry into relevant markets; (vi) obtain
reimbursement for sales of its products; (vii) establish sales, marketing,
distribution and development collaborations; and (viii) demonstrate the
competitiveness of the Company's products and systems.

Market Acceptance

Although end customer sales of PLAS+SD by the Red Cross have risen since the
product was introduced, end-user market penetration has increased at a slower
rate than anticipated. Successful market acceptance of the Company's products
and systems will largely depend on the Company's ability to demonstrate their
safety, efficacy and cost-effectiveness. The Company will need to convince
patients, doctors, health care providers, blood centers and other participants
in the blood products market to pay for the incremental cost of the Company's
virally inactivated plasma and, if successfully developed and approved for
marketing, the Company's other virally inactivated blood products, as compared
to widely used, lower priced, corresponding blood products that have not been
virally inactivated.

Government Regulation

All of the Company's products are subject to extensive regulations by the
federal government, principally the FDA, and state, local and non-U.S.
governments. Such regulations govern, among other things, the development,
testing, manufacturing, labeling, storage, pre-market clearance or approval,
advertising, promotion, sale and distribution of such products. The process of
obtaining regulatory approvals is generally lengthy, expensive and uncertain.
Satisfaction of pre-market approval or other regulatory requirements of the FDA,
or similar requirements of non-U.S. regulatory agencies, typically takes several
years, depending upon the type, complexity, novelty and intended purpose of the
product.

The regulatory process includes pre-clinical studies and clinical trials of
each product to establish its safety and efficacy, and may include post-
marketing studies requiring expenditure of substantial resources. The results
from pre-clinical studies and early clinical trials conducted by the Company may
not be predictive of results obtained in later clinical trials, and there can be
no assurance that clinical trials conducted by the Company will demonstrate
sufficient safety and efficacy to obtain the requisite marketing approvals. The
rate of completion of the Company's clinical trials may be delayed by many
factors, including slower than anticipated patient enrollment or adverse events
occurring during the clinical trials. Data obtained from pre-clinical and
clinical activities are susceptible to varying interpretations, which could
delay, limit or prevent regulatory approval. In addition, delays or rejections
may be encountered based upon many factors, including changes in regulatory
policy during the period of product development. The Company's clinical
development plan for its cellular products assumes that only data from in vitro
studies, not from clinical trials, will be required to demonstrate efficacy in
inactivating viruses and that clinical trials for these products will instead
focus on demonstrating therapeutic efficacy, safety and tolerability of blood
components treated with the system. Although the Company has had discussions
with the FDA concerning the Company's proposed clinical plan for these products,
there can be no assurance that this plan of demonstrating safety and efficacy
will ultimately be acceptable to the FDA or

26


that the FDA will continue to believe that this clinical plan is appropriate. No
assurance can be given that any of the Company's development programs will be
successfully completed or that any further investigational new drug (IND) or
investigational device exemption (IDE) applications will become effective, that
clinical trials will commence as planned, that required United States or non-
U.S. regulatory approvals will be obtained on a timely basis, if at all, or that
any products for which approval is obtained will be commercially successful. As
a result of FDA reviews or complications that may arise in any phase of the
clinical trial program, there can be no assurance that the proposed schedules
for IND, IDE and clinical protocol submissions to the FDA, initiations of
studies and completions of clinical trials can be maintained.

Risk of Reliance on Manufacturing Facility and Equipment

The Company has a single manufacturing facility. Any catastrophic event that
interrupts production at this facility would have a material adverse effect on
the Company's business, financial condition and results of operations. In August
1996, the Company experienced a malfunction in its fractionation equipment that
resulted in the Company incurring expenses of $5.1 million, consisting of $4.1
million in replacement costs of Bayer's plasma and $1.0 million of unrecoverable
processing costs. There can be no assurance that the Company's fractionation
equipment will not malfunction in the future, resulting in additional
unanticipated costs. In addition, to achieve the level of production of PLAS+SD
required under the Company's agreement with the Red Cross, the Company will have
to operate its single, highly customized filling machine for extended periods
without interruption. Any significant damage to, or malfunction of, this filling
machine that cannot be repaired would require the Company to replace the
machine. The construction of a replacement machine could take as long as 18
months. While the Company has casualty insurance which it believes to be
consistent with industry standards, any extended interruption in the production
of plasma fractions or PLAS+SD would have a material adverse effect on the
Company's business, financial condition, results of operations and cash flows.

Reliance on Strategic Collaborators and Distribution Agreements

The Company is dependent on strategic collaborators for sales, marketing and
distribution support and for the development of certain products and product
candidates. The Company has entered into: (i) an agreement with Bayer to process
plasma fractions from plasma supplied by Bayer; (ii) an agreement with the Red
Cross for the distribution of the Company's virally inactivated plasma; (iii) an
agreement with U.S. Surgical for the sale, marketing and distribution of the
Company's virally inactivated fibrin sealant, if and when approved for
marketing; and (iv) an agreement with Pall for the development, sale, marketing
and distribution of any system incorporating the Company's viral inactivation
technology for red blood cell concentrates. Although the Company established its
own national sales force in December of 1998 to support the efforts of its
partners, the success of the Company depends, to a large extent, upon its
ability to develop and deliver products to Bayer, the Red Cross, U.S. Surgical,
Pall and, potentially other strategic collaborators. The Company's collaborators
may be unable to satisfy minimum purchase requirements or achieve projected
sales levels under the Company's collaborative agreements which could result in
the termination of such agreements, causing a material adverse effect on the
Company's business, financial condition and results of operations. In addition,
the Company may need to seek new collaborators or alliances to sell and
distribute future products or to establish its own direct commercialization
capabilities. Securing new corporate collaborators is a time-consuming process,
and there is no guarantee that the negotiations with new collaborators will
yield positive results. There can be no assurance that if the Company finds
additional corporate collaborators to assist in the commercialization of
existing or new product candidates, the terms of the arrangements will be
favorable to the Company. In addition, there can be no assurance that the
Company's strategic collaborators will not decide to distribute other products
that compete directly with the Company's products or new products developed by
competitors that may prove to be more effective, cost-efficient alternatives to
the Company's products. Each of the Company's collaborative agreements require
the Company to meet certain research and development and commercialization
milestones. In the case of each of these agreements, failure of the Company to
achieve one or more of these milestones on a timely basis, could have a material
adverse effect on the Company's receipt of funding and revenues under the
agreement and the continuation of the agreement. The failure to maintain
existing strategic alliances for whatever reason and to secure new alliances
would delay the commercialization of existing and future products.

Competing Technologies and Rapid Technological Change

The fields of transfusion medicine and therapeutic use of blood products are
characterized by rapid technological change. Accordingly, the Company's success
will depend, in part, on its ability to respond quickly to such change through
the development and introduction of new products and systems. Product and system
development involves a high degree of risk, and there can be no assurance that
the Company's product and system development efforts will result in any
commercial successes.

27


Technological developments by others may result in the Company's products
becoming obsolete or non-competitive before the Company is able to generate any
significant revenue.

The Company expects that all of its products and systems will encounter
significant competition. Any such product or system, once approved for
marketing, would compete with current approaches to blood safety, including
screening, donor retesting and autologous (i.e., self) donations, as well as
with future products and systems developed by medical technology,
biopharmaceutical and hospital supply companies, national and regional blood
centers, or certain governmental organizations and agencies. Many companies and
organizations that may be competitors or potential competitors have
substantially greater financial and other resources than the Company and may
have more experience in conducting pre-clinical studies and clinical trials and
other regulatory approval procedures.

Product Liability

The Company's operations will expose it to the risk of product liability
claims. There can be no assurance that the Company will not experience losses
due to any such claims. The Company maintains product liability insurance
coverage, but there can be no assurance that the Company's product liability
insurance will continue to be available to the Company on a cost-effective basis
and that such insurance will be adequate to cover any or all potential claims.
In the event that a claim is brought against the Company, liability for damages
beyond the extent of coverage under the insurance policy combined with the
expense of litigating such claim could have a material adverse effect upon the
Company's business, financial condition and results of operations.

Dependence on Key Employees

The Company's success is dependent upon its ability to retain its scientific
staff and, in particular, Dr. Bernard Horowitz, Executive Vice President and
Chief Scientific Officer of the Company. Dr. Horowitz, a leader in the field of
viral inactivation, leads the group of scientists who were inventors of most of
the Company's core technologies. Although the Company maintains key man
insurance on Dr. Horowitz, the loss of Dr. Horowitz could have a material
adverse effect on the Company's business, financial condition and results of
operations. The Company's competitive position in the blood products industry
depends on its continued ability to recruit and retain qualified scientific,
managerial and technical employees.

Uncertainty of Proprietary Technologies and Patents

The Company's success depends, in part, on its ability to obtain and maintain
patents, to protect its trade secrets, to operate without infringing upon the
proprietary rights of others and to prevent others from infringing on the
proprietary rights of the Company. The Company has exclusive licenses to patents
and patent applications covering critical components of its viral inactivation
technologies. There can be no assurance that any patents owned by or licensed to
the Company will afford protection against competitors or that any pending
patent applications now or hereafter filed by or licensed to the Company will
result in patents being issued. In addition, the laws of certain non-U.S.
countries do not protect the Company's intellectual property rights to the same
extent as do the laws of the United States. Medical technology patents involve
complex legal and factual questions and, therefore, their enforceability cannot
be predicted with certainty. There can be no assurance that any of the Company's
patents or patent applications, if issued, will not be challenged, invalidated
or circumvented, or that the rights granted thereunder will provide proprietary
protection or competitive advantages to the Company against competitors with
similar technology. Furthermore, there can be no assurance that the Company's
competitors will not obtain patent protection or other intellectual property
rights that would limit the Company's ability to use its technology or
commercialize products that may be developed. There can be no assurance that the
Company's planned or potential products will not be covered by third-party
patents or other intellectual property rights, in which case continued
development and marketing of such products would require a license under such
patents or other intellectual property rights. There can be no assurance that
such required licenses will be available to the Company on acceptable terms, if
at all. Litigation may be necessary to defend against or assert such claims of
infringement, to enforce patents issued to the Company, to protect trade secrets
or know-how owned by the Company or to determine the scope and validity of the
proprietary rights of others. Litigation or interference proceedings could
result in substantial costs and diversion of management focus.

Uncertainty Relating to Third-Party Reimbursement; Cost Containment

Successful commercialization of the Company's products is, in part, dependent
on the reimbursement policies of third-party payers for the costs of the
Company's products. Failure by doctors, hospitals and other users of the
Company's products or

28


systems to obtain reimbursement from managed care organizations (MCOs), private
health insurers, government authorities and other medical cost reimbursement
channels could adversely affect the Company's ability to sell its products and
systems.

Control by Existing Stockholders

The Company's current Directors and executive officers and their respective
affiliates control a majority of the outstanding Common Stock of the Company. As
a result, these stockholders are able to exercise significant influence over all
matters requiring stockholder approval, including the election of Directors and
approval of significant corporate transactions. Such concentration of ownership
may also have the effect of delaying, preventing or deterring a change in
control of the Company.

Stock Price Volatility

The Company's stock price, like that of other companies in its industry, is
subject to significant volatility. The stock price may be affected by, among
other things, clinical trial results and other product development related
announcements by the Company or its competitors, regulatory matters,
announcements in the scientific and research community, intellectual property
and legal matters, changes in reimbursement policies or medical practices or
broader industry and market trends unrelated to the Company's performance. In
addition, if revenues or earnings in any period fail to meet the investment
community's expectations, there could be an immediate adverse impact on the
Company's stock price.


Year 2000

Some of the Company's older computer software programs were written using two
digit fields rather than four digit fields to define the applicable year (i.e.,
"98" in the computer code refers to the year "1998"). As a result, time-
sensitive functions of those software programs may misinterpret dates after
January 1, 2000, to refer to the twentieth century rather than the twenty-first
century (i.e., "02" could be interpreted as "1902" rather than "2002" (the Year
2000 Issue)). This could cause system failures or miscalculations resulting in
inaccuracies in computer output or disruptions of operations, including, among
other things, inaccurate processing of financial information and/or temporary
inability to process transactions, manufacture products, or engage in similar
normal business activities.

Based on recent assessments, the Company determined that it will be required
to modify or replace limited portions of hardware and software so that those
systems will properly utilize dates beyond December 31, 1999. The Company
presently believes that with modifications and replacement of existing hardware
and software, the Year 2000 Issue can be mitigated. However, if such
modifications and replacements are not made, or are not completed timely, the
Year 2000 Issue could have a material impact on the operations of the Company.

The Company's plan to resolve the Year 2000 issue involves the following four
phases: assessment, remediation, testing, and implementation. To date the
Company has fully completed its assessment of all systems that could be
significantly affected by the Year 2000 Issue. The completed assessment
indicated that most of the Company's significant information technology systems
could be affected. That assessment also indicated that software and hardware
(embedded chips) used in production and manufacturing systems (hereafter also
referred to as operating equipment) also are at risk. Affected systems include
program logic controllers used in various aspects of the manufacturing process.
The Company is in the process of gathering information about the Year 2000
compliance status of its significant suppliers and subcontractors and continues
to monitor their compliance.

The Company has fully remediated and tested all information technology systems
for Year 2000 Issues. The remediation of operating equipment is significantly
more difficult that the remediation of the information technology systems
because some of the manufacturers of the equipment are no longer in business.
The Company plans to complete remediation and testing of its operating equipment
by the end of July 1999. By June 1999, the Company is expected to have
contingency plans in place for its critical applications, which primarily
involve manual workarounds.

The Company has no systems which directly interface with either customers or
vendors. The Company has queried, and is in the process of collecting responses
from its important suppliers and contractors that do not share information
systems with the Company (external agents). To date, the Company is not aware of
any external agent Year 2000 issue that would materially impact the Company's
results of operations, liquidity, or capital resources. However, the Company has
no means of ensuring that external agents will be Year 2000 ready. The inability
of external agents to complete their Year 2000 resolution process in a timely
fashion could materially impact the Company. The effect of non-compliance by
external agents is not determinable.

The Company will utilize both internal and external resources to reprogram,
replace, test, and implement the operating equipment and related software for
Year 2000 modifications. The total cost of the Year 2000 project is estimated at
$375,000 and is being funded through operating cash flows. Through the year
ended January 2, 1999, the Company had incurred approximately $50,000 (all of
which has been expensed), relating to all phases of the Year 2000 project. Of
the total remaining project costs, approximately $250,000 is attributable to the
purchase of new software and operating equipment, which will be capitalized. The
remaining $75,000 relates to continued Year 2000 compliance monitoring and
repair of hardware and software and will be expensed as incurred.

The Company's plans to complete the Year 2000 modifications are based on
management's best estimates, which were derived utilizing numerous assumptions
of future events including the continued availability of certain resources, and
other factors. There can be no guarantee that these estimates will be achieved
and actual results could differ materially.

The information above contains forward-looking statements, including without
limitation, statements relating to the Company's plans, strategies, objectives,
expectations, intentions, and adequate resources that are made pursuant to the
"safe harbor" provisions of the Private Securities Litigation Reform Act of
1995. Readers are cautioned that forward-looking statements about the Year 2000
should be read in conjunction with the Company's disclosures under the heading:
"Forward Looking Statements."

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Company's earnings and cash flows are subject to fluctuations due to
changes in interest rates primarily from its investment of available cash
balances in money market funds with portfolios of investment grade corporate and
U.S. government securities and, secondarily, its long-term debt arrangements.
Under its current policies, the Company does not use interest rate derivative
instruments to manage exposure to interest rate changes.
