Item 1.  BUSINESS

Overview

         We are a leading developer of innovative biotechnology products
designed to improve the safety of the world's blood supply. We have designed our
proprietary INACTINE(TM) technology to inactivate a wide range of known and as
yet unknown viruses, bacteria and parasites from red blood cells while
preserving the therapeutic properties of the red blood cells. The INACTINE(TM)
system has also demonstrated the ability to remove in a highly efficient fashion
prions that may cause "Mad Cow Disease" in cows and the human form of the
disease, variant Creutzfeldt-Jakob Disease ("vCJD") Our lead product candidate,
INACTINE(TM) red blood cell system for pathogen reduction, is expected to soon
enter Phase III clinical trials. We are designing our INACTINE(TM) system to
work with existing red blood cell bag and collection systems and to be easily
integrated into the blood banking infrastructure.

         Blood safety and availability remain a significant concern as new
pathogens are discovered and the demand for blood products continues to
increase. To reduce the risk of contamination of the blood supply with
pathogens, blood banks currently screen donors using detailed questionnaires and
screen the donated blood for five known pathogens. Although these safety
measures have increased the safety of blood products overall, the risk of
transmitting known and unknown pathogens remains. Our goal is to diminish this
risk with our INACTINE(TM) technology.

         In order to accelerate product development and commercialization of our
INACTINE(TM) technology, we are actively engaged in strategic alliances with
Pall Corporation, Haemonetics, and Amersham Pharmacia Biotech.

         In collaboration with Oxford University, we are developing a diagnostic
test for pathogenic prions using aptamer technology. In their pathogenic form,
prions are the agents that cause Mad Cow Disease in cows and variant
Creutzfeldt-Jakob Disease in humans, which is 100% fatal and for which no
therapy or diagnostic currently exists.

Market Opportunity

         The global market for blood products is large and growing. Over 40
million units of whole blood are collected each year in the United States,
Europe and Japan, yielding over 40 million units of red blood cells for
transfusion. Worldwide, approximately $4 billion is spent each year on red blood
cells. Over one-third of all transfusions occur in the United States, where it
is estimated that one out of every three Americans will receive a transfusion at
some point during his or her lifetime. Driven by an aging population susceptible
to illness, increased prevalence of new disease and a rise in the number of
major surgeries performed, blood use in the United States grew almost 10 percent
between 1997 and 1999. Blood use, particularly units of red blood cells, is
expected to continue to increase as aggressive therapeutic treatments requiring
chronic transfusions become more routine.

         Demand for blood products continues to increase as the supply of blood
is constrained by increasingly restrictive donor selection and other blood
safety policies. Reports of supply shortages continue to increase on a regional
and national basis. The continued tightening of the donor exclusion criteria for
individuals has exacerbated shortages.

         According to a 2000 University of Michigan study, only 15 percent of
Americans today view the blood supply as safe, down from 48 percent in 1988.
Blood safety concerns caused by transfusion-transmitted diseases such as AIDS
and Hepatitis C have made a "zero-defect" blood supply the goal of regulators
around the world, including the FDA. We believe these dynamics create
significant demand for products that make blood safer.

Industry Background

         In the United States, the American Red Cross collects nearly half of
the country's blood supply. The next two largest blood banks are United Blood
Services and the New York Blood Center. The rest of the industry consists of
smaller independent blood banks. The Japanese and European blood markets are
even more concentrated. For example, in Japan, which collects 15 percent of the
world's transfusion blood supply, the Japanese Red Cross collects all of the
blood supply.

         Blood banks collect, separate and process whole blood from donors at
either mobile or fixed collection sites. After collection, whole blood is
separated into the following components, which are then distributed to hospitals
for storage and transfusion:

                                       4

<PAGE>

         .    Red Blood Cells. Red blood cells transport oxygen and carbon
              dioxide throughout the body. Red blood cells are frequently
              administered to patients who have anemia, trauma, surgical
              bleeding or genetic disorders and account for the majority of
              transfusions. Red blood cells have a shelf life of 42 days. We
              estimate the average price paid by hospitals in the United States
              in 2001 for red blood cells was $130 per unit.
         .    Plasma. Plasma is the liquid part of the blood and contains a
              large number of proteins with important therapeutic applications.
              Plasma is frequently administered to patients to mediate and
              control blood clotting, provide immune protection, and treat
              several rare and life-threatening diseases. Plasma can be frozen
              after collection and stored for up to one year in the form of
              fresh frozen plasma. We estimate the average price paid by
              hospitals in the United States in 2001 for plasma was $50 per
              unit.
         .    Platelets. Platelets initiate blood clotting and facilitate the
              repair of damaged blood vessels. Platelets are often administered
              to cancer patients following chemotherapy and to other patients
              who have lost large volumes of blood as a result of trauma or
              during surgery. Platelets have a shelf life of five days. We
              estimate the average price paid by hospitals in the United States
              in 2001 for platelets was $50 per unit.
         .    White Blood Cells. White blood cells, or leukocytes, are comprised
              of many different types of cells that form part of the body's
              immune system and play a major role in wound repair. White blood
              cells are rarely transfused as a separate component because of the
              potential for an adverse immune response by the recipient.

         The demand for blood products is ultimately driven by hospital-based
physicians, particularly surgeons, in the acute care setting. Hematologists and
oncologists also prescribe most of the blood used to treat chronic diseases such
as cancer.

         Maintaining adequate supplies of safe blood products is an increasing
challenge for blood centers around the world. In late summer 2000, the American
Red Cross reported that two-thirds of its collection centers had no more than
one day's supply of the necessary blood components. While collections increased
in 2001 by 7.1 percent over 2000, according to the National Blood Data Resource
Center, this increase reflected the spike in collections immediately following
September 11, 2001. Subsequently, collections have returned to previous levels
and inventories are again becoming dangerously low.

         Most blood centers rely on volunteer donors to donate blood for
transfusion, but less than five percent of healthy Americans eligible to donate
blood do so each year. More rigorous screening and stricter donor exclusion
criteria have reduced the number of previously eligible donors. For example, due
to fears of vCJD, which has resulted in approximately 100 deaths in the United
Kingdom alone, the FDA guidelines currently exclude potential donors who have
spent a total of six months or more in the United Kingdom between 1980 and 1996.
The FDA has issued proposed rules to be implemented in 2002 that would exclude
persons who have spent more than a cumulative three months in the United Kingdom
during this time period or a cumulative five years in other countries in Europe.
The FDA estimates that approximately five percent of currently eligible donors
will be excluded if these proposed rules are fully implemented.

Current Approaches to Blood Safety

         The following approaches are currently being used or are under
development to reduce the risk of having a blood supply contaminated with
pathogens and to maintain an adequate supply of blood products.

         Donor Exclusions. Regulatory agencies increasingly rely on tightened
donor exclusion criteria to reduce the risk of transmitting infections caused by
viruses, bacteria, parasites and prions. In the United States, all donors are
screened confidentially immediately prior to donation. A trained healthcare
professional questions the prospective donor regarding his or her current
health, health history, sexual habits, drug usage and travel outside the United
States.

     Screening Donated Blood. In the United States, Europe, and Japan, donated
blood undergoes screening for five different infectious disease-causing
pathogens:

         .    four viruses:
                   Hepatitis B, or HBV;
                   Hepatitis C, or HCV;
                   human immuno-deficiency virus, or HIV; and
                   human T-cell lymphotropic, or HTLV, and
         .    one bacteria, syphilis.

Three types of screening tests are currently used - antibody, antigen, and
nucleic acid testing. Antibody tests detect the body's response to a virus.
Antigen tests detect antigens on the surface of the virus itself. Nucleic acid
testing, or NAT, used in Europe to screen for the presence of HIV and Hepatitis
C, employs a relatively new technology that directly tests for evidence of the
pathogen itself. NAT enables earlier detection of a pathogen because it detects
genetic material of a virus, its DNA or RNA,

                                       5

<PAGE>

instead of waiting for the human body to mount a detectable response to a virus.
NAT is currently being used by blood banks under an investigational new drug
application in the United States to screen for HIV and HCV.

         Donation Strategies. Autologous, or self, donation is a strategy that
can be used by patients undergoing scheduled surgery to avoid the risk of
receiving contaminated blood. Prior to a scheduled surgery, the patient can
arrange to have his or her own blood taken and stored for later transfusion. A
related strategy, quarantining, a method used for plasma, requires that blood be
stored for three to six months after donation, at which time the donor must
return to the blood bank to undergo additional testing. If there are no
detectable pathogens in the donor's blood after this additional testing, the
donated blood may be used for transfusion.

         Leukocyte Reduction and Gamma Irradiation. Leukocyte reduction, which
is used to remove leukocytes, or white blood cells, from blood, is a standard of
care in many European countries where all donated blood is filtered to remove
leukocytes prior to transfusion. We estimate that 40 to 50 percent of all red
blood cell units processed in the United States are currently leukoreduced.
Gamma irradiation, which is a method of destroying white blood cells, has been
used more frequently over the past few years. Gamma irradiation involves
exposing blood products to radioactive isotopes which inactivate leukocytes. We
estimate that 10 to 20 percent of red blood cells in the United States are gamma
irradiated, while 100 percent of red blood cells are gamma irradiated in Japan.
Currently, gamma irradiation is used primarily to destroy lymphocytes, a type of
leukocyte that can cause graft versus host disease, which is the body's
rejection of transfused blood, after transfusion.

         Blood Substitutes or Temporary Oxygen Carriers. Several companies are
developing blood substitutes designed to mimic the therapeutic properties of
blood components. These products fall into two general categories, those that
are based on the blood's own hemoglobins and those that are synthetic
substitutes. Hemoglobin-based substitutes require donated blood from either
people or cows; synthetic substitutes, generally oxygen carriers, are designed
to dissolve gases, moving oxygen from the lungs to organs and removing carbon
dioxide.

         Pathogen Inactivation. Pathogen inactivation depletes or inactivates a
limited number of pathogens in blood, which improves the safety of the blood
product instead of simply testing for the presence of pathogens. Current
pathogen inactivation approaches are only applicable for plasma derivatives and
transfusion plasma.

Limitations of Current Approaches to the Safety of the Blood Supply

         Each of the current approaches is limited in its scope, effectiveness,
or practicality.

         Donor Exclusions. Although donor screening has been used for decades,
it remains limited because it relies heavily on the honesty and the cooperation
of the donor. In addition, it is only designed to exclude donors who are more
likely to be at risk for diseases known to be transmissible through blood. In a
time where maintaining adequate supplies of safe blood products is increasingly
challenging, donor exclusions can inadvertently increase the magnitude of that
challenge. There is also no guarantee that the donor will return once the
deferral period has lapsed.

         Screening Donated Blood. The principal limitation on current screening
procedures is their limited scope - in the United States, Europe, and Japan,
blood is only screened for five pathogens - HIV, HBV, HCV, HTLV and syphilis.
Therefore, current screening methods are not used to detect other known
pathogens. In addition, they cannot detect unknown or emerging pathogens, which
have historically presented a threat to the blood supply. For example,
scientists estimate that HIV was present in the blood supply for at least seven
years before it was identified as the agent that causes 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 percent of patients with
severe hemophilia. Similarly, of the four million Americans infected with HCV,
the most common chronic blood borne viral infection in the United States, more
than one million were infected through HCV infected blood products. Although HCV
was first identified in 1988, donated blood was not screened for HCV until 1992.

         In addition, most tests for known pathogens cannot detect the presence
of viruses during the infectivity window, the period during which viruses are
present in the blood but are not yet detectable. NAT provides only limited
incremental benefits, because it is effective only for specific viruses for
which the testing is performed.

         No tests have been implemented for certain pathogens that are known to
be prevalent in the blood supply, such as SEN V and parvo B-19 virus. The latter
virus has been reported to cause rashes, arthritis and has also been implicated
in miscarriages in pregnant women. Moreover, there are no practical tests
available to detect the presence of pathogenic prions. In addition, bacteria and
many other agents are known to 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

                                        6

<PAGE>

may also be transmitted by transfusion; however, there are no practical tests
used for these pathogens. Animal studies have indicated that the pathogenic
prions known to cause Mad Cow Disease and vCJD can be transmitted by blood but
no diagnostic tests exist to determine the presence of these specific prions in
blood. Although there have been no reports of vCJD being transmitted through
blood transfusions in humans, prion-related diseases remain a significant public
health concern.

         Donation Strategies. Autologous donation is impractical for most
patients and impossible when a transfusion is required due to trauma.
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 remains subject to limitations associated with blood screening.

         Leukocyte Reduction and Gamma Irradiation. Leukocyte reduction is
effective at removing white blood cells, but does little to reduce the existence
of other pathogens in blood products other than cytomeglavirus. Gamma
irradiation provides a narrow range of efficacy - insufficient treatment can
leave white blood cells in the blood, while excessive treatment can impair the
therapeutic function of the desirable blood components being transfused. In
addition, irradiated red blood cells have a decreased survival rate, resulting
in a reduced shelf life.

         Blood Substitutes or Temporary Oxygen Carriers. Blood substitutes are
being developed to simulate specific therapeutic characteristics of blood and
are not intended to replace whole blood components, such as red blood cells, for
most conditions. The few substitutes available today remain effective only for
approximately 24 to 48 hours in the blood, making the substitutes inadequate for
treatment of indications requiring chronic transfusion, which we believe to be
the fastest growing segment of blood use.

     Pathogen Inactivation. There is currently no pathogen inactivation process
available for red blood cells. Additionally, existing pathogen inactivation
approaches are only applicable to plasma and are limited in the scope of
pathogens they can inactivate.

Our Solution

         We believe that our proprietary INACTINE(TM) red blood cell system for
pathogen reduction offers the following advantages over current approaches to
blood safety:

         .     Inactivates known pathogens. Our INACTINE(TM) system inactivates
               a broad range of pathogens known to be transmitted through
               donated red blood cells, such as HIV, Hepatitis C, as well as
               pathogens for which screening is not currently conducted, such as
               parvo B-19 virus. The INACTINE(TM)system also inactivates other
               classes of pathogens for which no practical technologies exist to
               screen the blood. This includes gram negative and gram positive
               bacteria and parasites such as those that cause Malaria and
               Chagas Disease.
         .     May inactivate unknown pathogens. Based on preclinical testing
               focused on inactivating known pathogens, INACTINE(TM) has the
               potential to inactivate a wide range of pathogens in red blood
               cells.
         .     Purer red blood cells. Our INACTINE(TM) system reduces the amount
               of impurities such as cytokines in red blood cell units which may
               lead to fewer allergic reactions from patients receiving blood
               transfusions.
         .     Highly efficient removal of prion proteins. Our INACTINE(TM)
               system has demonstrated the ability to remove prion proteins from
               red blood cells. This ability may lead to the relaxing of current
               donor exclusion criteria implemented in an effort to reduce the
               spread of Mad Cow Disease.
         .     Potentially eliminate the need for gamma irradiation. Based on
               our preclinical testing, we believe our INACTINE(TM) system is at
               least as effective as gamma irradiation for the elimination of
               leukocytes that cause graft versus host disease without limiting
               the therapeutic properties of red blood cells.

Our Strategy

         Our objective is to establish our INACTINE(TM) technology for pathogen
reduction as the industry standard for blood product safety. The key elements of
our strategy include:

         .     Be the first to market in the largest segment. We are focusing
               our INACTINE(TM) technology on red blood cells, the largest
               segment of transfusion blood components in the United States,
               Europe and Japan. Our INACTINE(TM) red blood cell system for
               pathogen reduction completed a Phase II clinical trial and is
               expected to soon enter Phase III trials in the United States. If
               necessary, we will conduct supportive studies in select countries
               in parallel with these Phase III studies. Assuming we obtain
               positive results from the Phase III clinical trials in the United
               States, we will submit a biologic license application to the FDA.
               Subsequently, we intend to submit marketing applications in
               Europe and Japan using our Phase III data from the United States
               as well as any other appropriate studies.
         .     Maintain and pursue strategic alliances. We intend to maintain
               our existing strategic alliances. To date, we have established
               strategic alliances for our INACTINE(TM) technology with Pall
               Corporation, Haemonetics Corporation

                                       7

<PAGE>

          and Amersham Pharmacia Biotech. We have also entered into a sponsored
          agreement with Oxford University and a license agreement with ISIS
          Innovation Limited for the development of aptamer technology as a
          prion diagnostic. Collectively, these strategic alliances are
          important to advancing our INACTINE(TM) and aptamer technologies from
          development to commercialization. We intend to pursue additional
          strategic alliances with companies whose technologies and business
          strengths complement ours.
     .    Promote the benefits of our INACTINE(TM) system for red blood cells.
          We intend to work closely with regulatory agencies, third party
          payers, the medical community and healthcare consumers to build
          awareness about the benefits of using our pathogen reduction
          technology for blood products. Our goal is to establish our
          INACTINE(TM) system for red blood cells as the industry standard for
          blood product safety.
     .    Maintain flexible commercialization and distribution alternatives. We
          are currently building an INACTINE(TM) processing center to
          demonstrate the INACTINE(TM) system for red blood cells. Once our
          center is fully operational, INACTINE(TM) treated red cell units will
          be produced and we intend to include the center as part of our
          licensing application for our INACTINE(TM) system for red blood cells.
          This will provide us and our customers with flexibility in how we can
          scale up and introduce the technology in the United States.

Our Technology

INACTINE(TM)

     We have identified a family of small molecular compounds that penetrate
blood-borne viruses, bacteria, and other pathogens. Our INACTINE(TM) compound
for red blood cells, referred to as PEN110, is a highly water soluble, stable
and low-molecular weight compound. This compound selectively binds and
irreversibly modifies nucleic acids, including both DNA and RNA. The compound is
activated when it forms a weak bond with the negatively-charged sites within DNA
and RNA, after which the compound forms a permanent bond with its guanine in
DNA, or guanasine in RNA, the key building blocks of nucleic acid. This bond
prevents the replication of the nucleic acid. As the vast majority of pathogens
have DNA and RNA and pathogens need to replicate to survive and grow, preventing
the replication of the nucleic acid effectively kills the pathogens. Blood
components, such as red blood cells, plasma and platelets, do not contain
nucleic acid and, based on our clinical studies, PEN110 maintains the
therapeutic properties of the red blood cell. In addition to its pathogen
reduction capabilities, because PEN110 is a stable and small molecule, it can
penetrate the tight protein coat of non-enveloped viruses, such as parvo B-19
virus, which are small, difficult to kill viruses that do not have an outer
lipid envelope surrounding them.

     The following basic steps are involved in our INACTINE(TM) red blood cell
system:

     .    PEN110 is mixed with a unit of red blood cells;
     .    the mixture is aseptically transferred to a bag and treated for 18 to
          24 hours at room temperature; and
     .    the mixture is transferred to a fully-automated cell washing system,
          which we exclusively license from Haemonetics Corporation, to remove
          inactivated pathogens, cell debris, proteins, including prion
          proteins, and PEN110.

     The result is a unit of pathogen-inactivated washed red blood cells that is
ready for transfusion.

     Our preclinical research indicates that the cell washing process we use to
remove PEN110 has the potential to remove substantial levels of proteins,
including prion proteins, and cytokines from red blood cells. This feature of
our INACTINE(TM) system could provide an important competitive advantage over
other approaches by further reducing pathogen levels.

Our Aptamer Technology

     Aptamers are sub-strands of DNA and RNA that have the property of folding
in a variety of shapes. Our scientists can create large libraries of aptamers
and using technologies for high throughput drug screening, can identify aptamers
with a high affinity to differentially bond to a specific target. Our target for
an aptamer diagnostic is the prion for the diagnosis of Mad Cow Disease or vCJD.

     Prions are proteins and, therefore, do not contain RNA or DNA. Normal
benign prion proteins can be induced to change shape (misfold) to an infectious
form. A successful, broadly used diagnostic screen for the presence of
pathogenic prion proteins, we believe, must be able to differentiate between the
pathogenic and non-pathogenic form of the prion. We further believe the aptamer
to be an ideal candidate as a preferential high affinity binder. We are
collaborating with researchers at Oxford University in the United Kingdom to
identify that specific aptamer (lead candidate). Our goal is to identify a lead
candidate in 2002 that can be further developed into a diagnostic for use in
both human and veterinary screening.

</TABLE>

     Pre-Clinical Studies

     Our pre-clinical studies focused on determining the range of viruses and
bacteria that our INACTINE(TM) red blood cells system could inactivate, as well
as the reduction of parasites and lymphoctyes. In these studies, PEN110
demonstrated effectiveness against a broad spectrum of enveloped and
non-enveloped viruses and gram negative and gram positive bacteria, and
parasites. In addition, our pre-clinical studies focused on the effect of
INACTINE(TM) on the therapeutic properties of red blood cells and blood storage
time. In vivo testing of baboons with INACTINE(TM) treated red blood cells
resulted in no detectable adverse effects on the cellular properties of the red
blood cells and did not affect their 24-hour post-transfusion survival. We also
demonstrated in our baboon studies that the levels of survival of red blood
cells were equivalent to those of the untreated control group after one day and
28 days.

     Phase I Clinical Study

     We designed our Phase I clinical study of our INACTINE(TM) technology to
further evaluate the effect of INACTINE(TM) on the therapeutic properties of red
blood cells and blood storage time after a six-hour INACTINE(TM) treatment of
red blood cells followed by a 28-day storage period. This study involved 12
healthy adults using a randomized crossover design, meaning that each
participant received a treatment of the INACTINE(TM) treated red blood cells and
standard red blood cells sequentially. In the study, we collected a red blood
cell unit from each participant. We then treated half of these units with 0.1%
INACTINE(TM) for six hours followed by cell washing. We stored the INACTINE(TM)
treated and untreated red blood cells for 28 days. This study effectively
demonstrated a 28-day shelf life for INACTINE(TM) treated red blood cells and
equivalent functionality or recovery of INACTINE(TM) treated red blood cells
compared to control red blood cells in healthy participants. In addition, the
participants had no adverse reactions to the transfusions.

     Phase II Clinical Study

     We designed our Phase II clinical study for our INACTINE(TM) technology to
evaluate a 24-hour INACTINE(TM) treatment of red blood cells, a maximum storage
period and full unit transfusion safety. This study involved 72 healthy adults
divided into three groups based on the storage time of the INACTINE(TM) treated
red blood cells: 28 days, 35 days and 42 days. This study effectively
demonstrated that a 24-hour treatment period and a 42-day storage life for
INACTINE(TM) treated red blood cells is possible and that this treatment period
and storage time did not affect the 24-hour survival of the red blood cells. In
addition, the participants had no adverse reactions to the transfusions.

     Phase III Clinical Studies

     Our Phase III clinical trial program is awaiting FDA approval. We are
hopeful to receive approval and to begin in the first half of 2002. The trial
will focus on the safety of INACTINE((TM)) treated red blood cells. We expect to
conduct two studies, one in an acute surgical setting and the other in a chronic
setting, such as sickle cell anemia where patients require transfusions on a
chronic basis. Together, enrollment will be approximately 300 to 400 patients in
these studies.

     International Clinical and Regulatory Status

     We intend to discuss our clinical and regulatory plans in Europe and Japan
with the relevant regulatory agencies for their agreement. If agreed to by the
relevant regulatory agencies, we intend to use our United States clinical data
as a basis for submissions in Europe and Japan. If necessary, we may also choose
to conduct smaller supportive studies in select countries in parallel with our
Phase III clinical studies in the United States. We also intend to submit
marketing applications in Europe and Japan in late 2003 or early 2004 using our
Phase III clinical data.

Strategic Alliances

     We believe that we can efficiently accelerate the commercialization of our
products by entering into strategic alliances for sales, marketing, distribution
and complementary technologies. To date, we have entered into strategic
alliances with Pall Corporation, Haemonetics Corporation, and Amersham Pharmacia
Biotech for the commercialization of INACTINE(TM) technology, and a sponsored
research agreement with Oxford University and a license agreement with ISIS
Innovation Limited for the aptamer technology.

Pall Corporation

     In February 1998, we entered into a series of agreements with Pall to
collaborate on the development and marketing of systems employing our pathogen
reduction technologies for red blood cell and platelet concentrates. Pall is a
leading manufacturer and distributor of filtration products, including those
relating to the collection, preservation, processing, manipulation, storage and
treatment of blood and blood components. Pall will make up to $26.0 million in
equity investments tied to financing and development milestones. In return, Pall
receives exclusive worldwide distribution rights to any system incorporating our
pathogen reduction technology for red blood cells or platelets. Both companies
have agreed to share in profits on a 50/50 basis as well as in research,
development, clinical and regulatory responsibilities and all operational costs.
During fiscal 2001, Pall provided $5.8 million in research funding. To date, of
the $26.0 million equity investment, Pall has invested a total of $16.0 million.
The joint development, marketing and distribution agreement will continue so
long as systems are being developed or marketed, unless terminated upon a
material breach by the other party if not cured within a specific period of
time, not less than 30 days from when notice is given. At December 29, 2001,
Pall owns approximately 10 percent of our outstanding shares.

Haemonetics Corporation

     In January 2000, we entered into a development and manufacturing agreement
with Haemonetics. Haemonetics is one of the leading developers of automated
blood collection equipment and disposables. The Haemonetics system is the only
"closed" cell washing system approved by the FDA. This closed system allows the
cells to be either immediately transfused or stored for later transfusion
similar to untreated red blood cells. We secured exclusive worldwide rights to
use the Haemonetics cell washing system as part of our INACTINE((TM)) red blood
cell system for pathogen reduction. When our INACTINE((TM)) red blood cell
system is commercialized, Haemonetics will provide contract manufacturing
services for the cell wash equipment and disposables. Pall will market the cell
wash system and disposables along with the balance of our INACTINE(TM) red blood
cell system under terms of our collaboration with Pall. We are paying
Haemonetics for some modifications to the cell wash system to adapt it for use
as part of our INACTINE(TM) red blood cell system. Through December 29, 2001, we
have paid Haemonetics $2.1 million for the development of the cell washing
system for use in the INACTINE system. This agreement will terminate after ten
years unless extended by mutual agreement.

Amersham Pharmacia Biotech

     In April 2000, we entered into a license and distribution agreement with
Amersham Pharmacia Biotech to exclusively market and distribute our INACTINE(TM)
technology to manufacturers of biopharmaceuticals and transgenic products and to
plasma fractionators. Amersham Pharmacia Biotech is the life science business of
Nycomed Amersham plc. We retained all rights for the marketing and distribution
of our INACTINE(TM) technology with regard to blood components such as red blood
cells, platelets and plasma. We will provide Amersham Pharmacia Biotech with
technical support and training and conduct

                                       10

<PAGE>

research and development projects as directed by Amersham Pharmacia Biotech
during the duration of the agreement. Through December 29, 2001, we have
received $1.5 million from Amersham Pharmacia Biotech. We could also receive
further payments of $1.0 million subject to product testing and FDA approval
milestones. In addition, we will receive a percentage royalty based on net sales
made by Amersham Pharmacia Biotech that incorporate our INACTINE(TM) technology.
The duration of the agreement is ten years. Either party may terminate the
agreement due to a material breach that is not cured within 90 days. Amersham
Pharmacia Biotech has the right to terminate the agreement after 30 days written
notice to us after the initial evaluation phase. This termination right may not
be exercised before April 2003 or after April 2005.

Oxford University

         In May 2001, we entered into a ten-year exclusive license agreement
with ISIS Innovation Limited, or ISIS, an affiliate of Oxford University. Under
this agreement, we were granted a license to patents relating to aptamer
technology. We may use the technology to develop products and services in the
field of prion diagnostics and in vivo prion removal related products and
processes for food, agricultural, human and veterinary applications.
Additionally, if we use or market any licensed products, we will pay a royalty.
If either party commits a material breach and fails to cure within 30 days, the
other party may terminate by written notice. We may terminate by six months
written notice at any time.

         In April 2001, we also entered into an exclusive sponsored research
agreement with Oxford University for the development of the aptamer technology
as a diagnostic. We are also funding ongoing development work in the lab of a
leading Oxford infectious disease researcher and will make milestone payments
during the clinical trial process. Any intellectual property that is developed
as a result of this agreement will be owned by Oxford and exclusively licensed
to VITEX.

Patents, Licenses and Proprietary Rights

         Our policy is to seek to protect our proprietary position by, among
other methods, filing United States and foreign patent applications related to
our proprietary technology, inventions and improvements that are important to
the development of our business. We believe that the protection of our
proprietary technologies may create competitive barriers to entry into the
pathogen reduction market. We intend to continue to pursue our patent filing
strategy and to vigorously defend our intellectual property position against
infringement.

         As of December 29, 2001, our INACTINE(TM) patent portfolio consisted of
six issued United States patents, two issued foreign patents and over fifty
pending United States and foreign patent applications. Our issued patents expire
at various dates between 2015 and 2020. Our INACTINE(TM) portfolio includes
patents and/or patent applications that generally relate to methods comprising
the use of pathogen reduction agents, methods of removing and/or quenching
pathogen inactivating agents, methods of synthesizing pathogen reduction agents,
and a blood collecting device comprising a pathogen inactivating agent.

         Our patent portfolio also consists of fourteen other pending United
States and foreign patent applications, covering applications relating to
methods of affinity purification, prion detection and virus detection.

         It is worth noting that:

         .   patent applications filed in the United States on or before
             November 28, 2000 generally are currently maintained in secrecy
             until patents are issued;

         .   patent applications filed in the United States after November 28,
             2000 and patent applications filed in other countries generally
             are not published until 18 months after they are first filed in
             any country;

         .   publication of technology developments in the scientific or
             patent literature often lags behind the date of these
             developments; and

         .   searches of prior art may not reveal all relevant prior
             invention.

         We cannot be certain that we were the first to invent the subject
matter covered by our patents and patent applications or that we were the first
to file patent applications for our inventions or that a court or patent
authority will not determine that our patent rights are invalid or unpatentable.

         We believe that several elements of our pathogen inactivation program
involve unpatented proprietary technology, processes, know-how, or data,
including fermentation and production process and purification technology. With
respect to proprietary technology, know-how and data which are not patentable or
potentially patentable or processes other than production processes for which
patents are difficult to enforce, we have chosen to protect our interests by
relying on trade secret protection and confidentiality agreements with our
employees, consultants and certain strategic partners. All of our key employees
and scientific researchers are parties to confidentiality agreements. The
confidentiality agreements and other trade secret protection may not provide
meaningful protection and may be breached. We may not have adequate remedies for
any breach. Our trade secrets may otherwise become known or be independently
developed by competitors.

                                       11

Competition

         Our 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 we compete are characterized by rapid and significant
technological changes. Accordingly, our success will depend in part on our
ability to respond quickly to medical and technological changes through the
development and introduction of new products. Many companies and organizations
including our principal competitors, Cerus Corporation and Gambro, that may be
competitors or our potential competitors have substantially greater financial
and other resources than we do and may have greater experience in conducting
pre-clinical studies and clinical trials and obtaining regulatory approvals. In
addition, other technologies or products may be developed that have an entirely
different approach or means of accomplishing the intended purposes of our
products, or that might render our technology and products obsolete.
Furthermore, we cannot be certain that our competitors will not obtain patent
protection or other intellectual property rights that would limit our ability to
use our technology or commercialize products that may be developed.

         Competition for INACTINE(TM) treated red blood cells may come from
alternative approaches to the problem of improving the safety of blood and blood
products and from alternative pathogen reduction technologies. The alternative
approaches to achieving safer blood component products include donor retesting,
the use of blood substitutes, leukocyte filters and reduction systems, improved
blood testing such as nucleic acid testing and gamma irradiation. All of these
approaches are currently available, and each has gained some degree of market
acceptance.

         In the area of pathogen 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 the our products. We
believe that the primary competitive factors in the market for pathogen
inactivation systems will include the breadth and effectiveness of pathogen
inactivation processes, compatibility of processes with cells and proteins, ease
of use, the scope and enforceability of patent or other proprietary rights,
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.

Government Regulation

         Our products under development will be 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 the development, testing, manufacturing, record keeping,
storage, labeling, advertising, promotion and pre-market approval of these
products.

         We believe that our red blood cell system incorporating our
INACTINE(TM) technology will be treated as a biologic regulated by the FDA's
Center for Biologics Evaluation and Research.

         Before a biologic may be marketed in the United States, the FDA must
approve a biologics license application, or BLA covering both the product and
the facility. Before a medical device may be marketed in the United States, the
FDA must clear a pre-market notification known as a 510(k) notice or approve a
pre-market application or PMA for the product. Before a combination product may
be marketed in the United States, it must have an approved BLA (or PLA/ELA) or
PMA.

         The steps required before a biologic or medical device may be approved
for marketing in the United States generally include:

         .   pre-clinical laboratory and animal tests;

         .   submission to the FDA of an investigational new drug exemption,
             or IND, for biologics, or an investigational device exemption, or
             IDE, for medical devices, for human clinical trials, which must
             become effective before such trials may begin;

         .   appropriate tests in humans to show the product's safety;

         .   adequate and well-controlled human clinical trials to establish
             the product's efficacy for intended indications;

         .   submission to the FDA of a BLA or PMA, as appropriate; and

         .   FDA review of the BLA or PMA in order to determine 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 the facilities and the
process used to manufacture the product comply with current good manufacturing
practices, or cGMP.

                                       12

<PAGE>

         We believe that, in deciding whether a pathogen inactivation system is
safe and effective, the FDA will consider the therapeutic efficacy of treated
blood components as compared to blood components which are untreated by the
system and that system safety and any other risks in the use of treated
components will be weighed against system benefits.

         Generally, similar regulatory requirements apply to products intended
for marketing outside the United States.

         The FDA could significantly limit the indicated use for which one of
our products can be marketed. The testing and review process requires
substantial time, effort and financial resources, and is generally lengthy,
expensive and uncertain. The approval process may be 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. Even if we are granted regulatory approval or clearance from the FDA,
we and our products will be subject to continuing review. 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 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 our planned products.

         In addition to the regulatory requirements applicable to us, there are
also regulatory requirements applicable to our 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 or BLAs from the FDA before
shipping products processed with our pathogen reduction systems. This
requirement and/or FDA delays in approving such supplements may deter some blood
centers from using our 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.

Organization and Operating History

         We are headquartered in Watertown, Massachusetts and were incorporated
in Delaware in 1992.

         On November 12, 1999, we merged with Pentose Pharmaceuticals, Inc.
Pentose was a development stage biotechnology company whose principal business
was the development and commercialization of novel anti-viral products for
medical use based on applications of nucleic acid chemistry. Pentose had
developed the INACTINE(TM) technology platform for the inactivation of pathogens
in blood components. The merger was effected through an all stock transaction
accounted for under the purchase method and valued at $38.8 million.

         On August 14, 2001, we completed the divestiture of our Plasma
Operations located in Melville, New York to Precision Pharma Services, Inc.
Precision was a newly-formed company owned by management of the Plasma
Operations and Ampersand Ventures, one of our shareholders. These operations
were responsible for producing intermediate plasma fractions for Bayer and for
viral inactivation of transfusion plasma for the Red Cross. The Plasma
Operations accounted for all of our previously reported processing revenues. The
total value of the transaction was approximately $34.0 million of which $25.0
million was received in cash at closing and an additional $2.0 million was
received on January 31, 2002 as a result of Precision achieving defined
financial goals. In addition, we will receive $3.0 million on the second
anniversary of the divestiture, subject to our indemnification obligations.
Based upon the transaction value in comparison with the net book value of the
Plasma Operations assets and liabilities sold plus related transaction costs, we
recorded a loss of $6.8 million on the transaction. Prior to the closing of the
transaction, we obtained a fairness opinion from an investment banker that the
transaction was fair to our shareholders.

         Our total costs over the last three fiscal years in our research and
development activities were as follows: fiscal year 2001-$20.2 million, fiscal
year 2000- $17.5 million and fiscal year 1999- $8.8 million.

Employees

         As of January 31, 2002, we had eighty-five employees, of whom
sixty-eight were engaged in research and development and seventeen were engaged
in general and administrative activities. Sixteen hold Ph.D.'s. We consider our
employee relations to be good.

Item 2.  PROPERTIES

         We currently lease 36,000 square feet of space in Watertown,
Massachusetts to accommodate our research and development activities. This lease
expires in 2009 with two options to extend the lease term by five years each. We
also lease 16,000 square feet of space in Stoughton, Massachusetts which we are
outfitting as a prototype processing center for our INACTINE(TM) red blood cell
system and for use in treating red blood cells during the Phase III clinical
trials. This lease expires in 2008 with one option to extend the lease term
through 2013. We believe that our current facilities are adequate for present
and foreseeable future uses.

Item 3.  LEGAL PROCEEDINGS

         We are not a party to any material legal proceedings.

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

fiscal years 2001, 2000, 1999, 1998 and 1997, respectively.

(1) During 2001, we incurred a $6.8 million charge on the divestiture of our
plasma operations (see note 3 to the consolidated financial statements).

(2) During 2000, we recorded a $1.2 million incentive sales credit reflecting
unused sales incentives from the program which commenced in 1999.

(3) Partner research funding includes collaborator reimbursement amounts
received from related parties in the amounts of $5.8 million, $4.0 million, $1.8
million, $2.3 million and $0.1 million in 2001, 2000, 1999, 1998 and 1997,
respectively. Cost of sales includes royalties and materials used in the
production of PLAS+(R)SD which were paid or owed to related parties in the
amounts of $0.9 million, $0.4 million, $0.8 million, $1.1 million and $0.8
million in 2001, 2000, 1999, 1998 and 1997, respectively.

(4) During 1999, we recorded a $4.5 million incentive sales charge (see note 12
to the consolidated financial statements). We negotiated a settlement with an
insurance carrier related to a 1996 plasma loss under which we received a cash
payment of $3.5 million. In connection with the merger with Pentose, we recorded
a $33.0 million write off of in-process research and development (see note 4 to
the consolidated financial statements). Additionally, in anticipation of the
merger, we recorded a research and development charge for $2.3 million for
severance and related expenses. We recorded a one-time charge of $2.6 million
for the voluntary recall of lots of PLAS+(R)SD (see note 13 to the consolidated
financial statements).

(5) For fiscal year 1998, we completed our IPO of 3,325,000 shares of our common
stock at a price of $12.00 per share, raising net proceeds of $35.9 million (see
note 9 to consolidated financial statements). In conjunction with the
collaboration agreement between ourselves and Pall Corporation, Pall acquired
$9.0 million of our common stock in two private placements, the second of which
closed contemporaneously with, and at the same price terms and conditions as the
IPO. We 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 12 to the consolidated
financial statements).

(6) In May 1998, we received FDA approval of our virally inactivated transfusion
plasma, PLAS+(R)SD, and commenced product sales in June 1998 (see note 12 to the
consolidated financial statements).

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


Recent Developments

         We divested our Plasma Operations located in Melville, New York on
August 14, 2001, as more fully discussed in note 3 to the consolidated financial
statements. This business was responsible for producing intermediate plasma
fractions for Bayer Corporation and for viral inactivation of transfusion plasma
for the American National Red Cross. The Plasma Operations accounted for all of
our historical revenues with the exception of partner research funding.
Management's Discussion and Analysis of Financial Condition and Results of
Operations following herein includes commentary on these now-divested Plasma
Operations. We have included herein, following the discussion of historical
results of operations and liquidity and capital resources, a section addressing
pro forma results of operations for our remaining operations covering fiscal
year 2001 as compared to fiscal year 2000.

         The consideration we received in exchange for substantially all the
assets and liabilities of the Plasma Operations was as follows, in thousands:

          Cash                                              $   30,000
          Liabilities assumed by Precision:
             Capital lease obligations                             880
             Advances from customers                             3,131
                                                            ----------
               Total                                        $   34,011
                                                            ==========


The cash consideration of $30.0 million includes a $3.0 million holdback by
Precision, payable after two years, subject to the satisfaction of
indemnification obligations. At closing, the Company received $25.0 million and
was eligible to receive additional consideration of up to $2.0 million if
Precision achieved certain financial goals. These goals were met in the fourth
quarter of 2001 and the $2.0 million contingent consideration was received from
Precision subsequent to year end. During fiscal 2001, we reported a loss of $6.8
million on the divestiture transaction.

Results of Operations

Fiscal Year 2001 as Compared to Fiscal Year 2000

Net revenues

          Processing revenues decreased 42 percent to $20.6 million for fiscal
year 2001 in comparison with $35.5 million in fiscal year 2000. The 2001 results
reflect a partial year of activity due to the divestiture of the Plasma
Operations on August 14, 2001. The Plasma Operations were responsible for all
reported processing revenues.

         Partner research funding, principally from Pall Corporation, increased
by $2.2 million or 55 percent to $6.3 million for the fiscal year 2001 versus
fiscal year 2000. The increase reflects the acceleration of our research and
development efforts in the INACTINE(TM) red blood cell program.

Cost of Sales

         Cost of sales was $15.7 million or 76 percent of processing revenues in
fiscal year 2001 versus $28.1 million or 79 percent of processing revenues in
fiscal year 2000. The decrease in cost of sales reflects lower processing volume
and the divestiture of the Plasma Operations in August 2001. As mentioned
previously, 2001 cost of sales was for a partial year due to the August 14, 2001
divestiture of the Plasma Operations.

Research and Development

          Research and development costs increased by $2.7 million to $20.2
million in fiscal year 2001 versus $17.5 million in

                                       17

<PAGE>

fiscal year 2000. Our increased spending is concentrated in our INACTINE(TM) red
cell pathogen reduction program which covered Phase II clinical trials in 2001.
The upward trend in spending should continue in fiscal 2002 as the INACTINE(TM)
red cell program moves forward in the clinic.

Selling, General and Administrative Expenses

         Selling, general and administrative expenses decreased $2.6 million in
fiscal 2001 to $7.8 million from $10.4 million in the prior year. The decrease
reflects the effects of the divestiture of the Plasma Operations on August 14,
2001. Going forward to fiscal 2002, we expect selling, general and
administrative expenses to be below fiscal 2001 spending level, into the range
of approximately $6.0 million.

Plasma Operations Divestiture

         During fiscal year 2001, we recorded a net charge of $6.8 million for
the divestiture of our Plasma Operations.

Provision for Income Taxes

         For fiscal years 2001 and 2000, we have recorded no income tax expense
or benefit. At December 29, 2001 and December 30, 2000, we established a full
valuation allowance against our net deferred tax asset positions of $38.4
million and $25.7 million, respectively. Realization of these net deferred tax
assets will be based on, among other things, our ability to generate future
taxable profits and utilize our net operating loss carryforwards and tax credits
before they expire.

Fiscal Year 2000 as Compared to Fiscal Year 1999

Revenues

         Processing revenues decreased 16 percent, or $7.0 million, to $35.4
million for fiscal year 2000 compared to $42.4 million for fiscal year 1999. The
sales decline was due to reduced PLAS+(R)SD business partially offset by gains
in plasma fractions. PLAS+(R)SD volumes were down and revenues declined 50
percent from the prior year reflecting shortfalls in the Red Cross plasma
deliveries.

         Revenue from plasma fractions increased 24 percent in comparison with
the prior year. Volume was constant during the year and processing fees were
increased slightly from 1999.

         In fiscal 1999 we entered into a one year sales incentive program with
the Red Cross to support their initiative to increase sales of PLAS+SD and to
reduce their inventory levels. We recorded a charge of $4.5 million against
revenues representing our estimate of program costs incurred based principally
on Red Cross inventories of PLAS+SD eligible under the program. The sales
incentive program concluded in fiscal year 2000. Red Cross sales incentives
earned under the program were $1.2 million below our initial estimate and this
amount was recorded as a credit to revenues in 2000.

         Partner research funding, principally from Pall Corporation, increased
124 percent, or $2.2 million, to $4.0 million for fiscal year 2000 compared to
$1.8 million for fiscal year 1999. The increase reflects the overall expansion
of our research and development efforts primarily in the INACTINE(TM) red blood
cell program. Also, fiscal year 1999 research funding was lower than normal
during the second half of 1999 as we initiated a restructuring of our research
program in anticipation of our merger with Pentose Pharmaceuticals, Inc.

         Taking into account the effects of the Sales Incentive Program in
fiscal years 2000 and 1999, net revenues increased 2 percent, or $1.0 million,
to $40.7 million for fiscal year 2000.

Cost of sales

         Cost of sales was $28.1 million, or 79 percent of processing revenues
for fiscal year 2000, compared to $24.7 million, or 58 percent of processing
revenues for fiscal year 1999. This provided gross margins of 21 percent and 42
percent for fiscal years 2000 and 1999, respectively. The increase in cost of
sales of $3.4 million reflected the 15 percent increase in fractionation
processing volume following the addition of new capacity at the end of fiscal
1999. PLAS+(R)SD cost of sales as a percentage of net revenue increased
significantly due to reduced plasma supply from the Red Cross causing lower
volumes and correspondingly lower absorption of fixed costs. We implemented a
workforce reduction in the third quarter of 2000 for the plasma operations in
order to lower our manufacturing cost structure and to better match our
production capacity to the expected Red Cross processing volumes for PLAS+(R)SD.
Severance and other costs recorded within cost of sales for the workforce
reduction amounted to $0.6 million.

Research and development

     Research and development costs increased $8.7 million for fiscal year 2000
to $17.5 million, compared to $8.8 million for fiscal year 1999. This increase
reflects the overall expansion of our research efforts and specifically the
increased spending on the INACTINE(TM) red blood cell pathogen reduction, as
well as the cost of Universal PLAS+SD Phase III clinical trials. Research and
development expenses during 1999 were reduced to a lower than normal level
during the second half of that year after we restructured our research program
to eliminate redundancies in anticipation of the November 1999 merger with
Pentose Pharmaceuticals, Inc.

Selling, general and administrative expenses

         Selling, general and administrative expenses increased $1.0 million for
fiscal year 2000 to $10.4 million, compared to $9.4 million in fiscal year 1999.
The increase in expenses was due to product support for PLAS+(R)SD early in the
year including marketing support to the New York Blood Center of $0.4 million.
Due to the workforce reduction in the third quarter of 2000, we eliminated
several sales and administrative positions and we recorded severance costs of
$0.1 million.

Charges related to Pentose merger

     In fiscal year 1999, we recorded restructuring costs of approximately $2.2
million for expenses related to the integration of our research and development
activities with those of Pentose Pharmaceuticals, Inc. These costs covered a
reduction in staffing levels and the elimination of duplicate facilities.

     We accounted for the Pentose merger as a purchase transaction valued at
$38.8 million and, accordingly, we recorded assets and liabilities at their fair
values. In-process research and development acquired in the transaction in the
approximate amount of $33.0 million was recorded as a charge against operations.

Charge related to product recall

     In fiscal year 1999, we executed a voluntary recall of lots of PLAS+(R)SD
that were found to contain heightened levels of parvo B-19 virus. We recorded a
charge in the amount of $2.6 million to cover the write-off of inventory lots,
production testing, other direct recall expenses and a reserve for an equitable
sharing of recall costs incurred by our exclusive distributor of PLAS+(R)SD, the
Red Cross.

Settlement of insurance claim

     We successfully resolved a dispute with our insurer, Vigilant Insurance
Company, over a 1996 claim that resulted from a malfunction in our manufacturing
equipment and in December 1999 we received a cash payment of $3.5 million.

Interest income (expense), net

     We incurred net interest expense of $0.1 million for fiscal year 2000
compared to net interest income of $0.1 million for fiscal year 1999. Lower cash
balances decreased interest earned from 1999.

Discount on customer advance

     In the amendment to the Red Cross Agreement effective April 1, 2000, the
non-interest bearing Red Cross advance was increased by approximately $0.5
million reflecting certain amounts owed under the sales incentive program and
was restructured to extend repayment terms. Upon discounting the new balance and
terms to present market value, we recorded a credit of $0.4 million.

Provision for Income Taxes

     For fiscal years 2000 and 1999, we have recorded no income tax expense or
benefit. At December 30, 2000 and January 1, 2000, we established a full
valuation allowance against our net deferred tax asset positions of $25.7
million and $18.0 million, respectively. Realization of these net deferred tax
assets will be based on, among other things, our ability to generate future
taxable profits and utilize our net operating loss carryforwards and tax credits
before they expire.

Liquidity and Capital Resources

     We have historically financed our operations through sales of common stock,
issuance of long-term debt and capital lease financing arrangements. In
addition, we generated cash from our Melville, New York Plasma Operations
business, which was sold on August 14, 2001. We also receive research and
development funding under a collaboration agreement with Pall Corporation, one
of our shareholders.

     At December 29, 2001, we had working capital of $23.4 million, including
cash and cash equivalents and short-term investments of $25.3 million, in
comparison with working capital of $4.5 million, including cash and cash
equivalents of $7.8 million at December 30, 2000. The primary objectives for our
investment of cash balances are safety of principal and liquidity. Available
cash balances are invested in money market funds and in portfolios of investment
grade corporate and U.S. government securities.

     During the fiscal year 2001, we increased our cash position through the
$25.0 million proceeds from the divestiture of our Plasma Operations, the $10.0
million proceeds from the sale of common stock to an outside investor, and the
$1.0 million proceeds from the issuance of stock under stock plans. These cash
inflows were offset by operating losses and changes in working capital of $12.9
million, investment in property, plant and equipment of $1.7 million, repayment
of capital lease obligations of $1.2 million and repayment of long-term debt of
$2.7 million.

     Under terms of the Plasma Operations divestiture (see note 3 to the
consolidated financial statements), we were entitled to contingent consideration
of up to $2.0 million if Precision met certain processing milestones. These
were fully achieved and we received payment of $2.0 million subsequent to year
end.

     Under our collaborative agreement with Pall Corporation, Pall is obligated
to make investments in our common stock at market price according to a series of
milestone events. We will be entitled to receive the next milestone investment
in the amount of $4.0 million shortly after initial treatment of patients in the
Phase III clinical trials for red blood cells which we expect to occur in the
first half of 2002.

     We expect that a combination of our cash and cash equivalent balances and
short-term investments, our research and development funding by
Pall Corporation, the upcoming equity milestones from Pall Corporation and the
Precision payment to be sufficient to meet our cash requirements over the next
fiscal year.

Pro Forma Results of Operations

     The following unaudited pro forma consolidated statements of operations are
based on the historical consolidated financial statements of our Company after
giving effect to our divestiture of the Plasma Operations as if the sale had
occurred on the first day of fiscal year 2000. In deriving these unaudited pro
forma consolidated statements, revenues, cost of sales, sales and marketing
costs and interest expense associated with the Plasma Operations were eliminated
from the historical consolidated financial statements. The results presented
here are not necessarily indicative of the results of operations that would have
been obtained had the sale actually occurred on the date set forth above.

Pro forma Fiscal 2001 as Compared to Pro Forma Fiscal 2000

Net revenues

     Partner research funding, principally from Pall Corporation, increased by
$2.2 million or 55 percent to $6.3 million for the fiscal year 2001 versus
fiscal year 2000. The increase reflects the acceleration of our research and
development efforts in the INACTINE(TM) red blood cell program.

Research and Development

     Research and development costs increased by $4.0 million to $20.1 million
in fiscal year 2001 versus $16.1 million in fiscal year 2000. Our increased
spending is concentrated in our INACTINE(TM) red cell pathogen reduction program
which covered Phase II clinical trials in fiscal year 2001.

Selling, General and Administrative Expenses

     Selling, general and administrative expenses were slightly higher in fiscal
2001 at $7.4 million versus $6.9 million in fiscal 2000 due to increased legal
costs.

                                       21

<PAGE>

Interest income, net

          Net interest income was $0.5 million for fiscal year 2001 compared to
$0.8 million for fiscal year 2000. This reflects higher cash balances in fiscal
2000 where, under the pro forma scenario, divestiture proceeds were received on
the first day of fiscal 2000.

Risk Factors that May Affect Future Results

          Our business faces significant risks. These risks include those
described below and may include additional risks of which we are not currently
aware or which we do not believe are material. If any of the events or
circumstances described in the following risks actually occurs, our business,
financial condition or results of operations could be materially adversely
affected. These risks should be read in conjunction with the other information
set forth in this report.

Our success depends on new products and systems in the development stage which
may not be commercialized.

          The success of our business depends on the successful development and
commercialization of pathogen reduction products and systems, including products
based on INACTINE(TM) and affinity purification technologies. We cannot ensure
that these products and systems will be successfully developed or
commercialized. Our pathogen 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. Successful commercialization of our
products and systems under development depends, in significant part, on our
ability to:

          .  complete their development in a timely fashion;
          .  demonstrate their safety in clinical trials;
          .  obtain and maintain patents or other proprietary protections;
          .  obtain required regulatory approvals;
          .  implement efficient, commercial-scale manufacturing processes;
          .  sell into relevant markets before competitors;
          .  obtain approval for reimbursement under health care systems; and
          .  establish and maintain sales, marketing, distribution and
             development collaborations.

We have historically incurred operating losses and these losses will continue.

          We have historically incurred substantial operating losses and we
expect these losses to continue for the foreseeable future. As of December 29,
2001, we had an accumulated deficit of approximately $108.8 million. Moreover in
August 2001, we divested our plasma operations which historically generated most
of our revenues. Going forward, until such time, if ever, that we complete
development of and successfully commercialize our products, our only significant
source of revenue will be from research collaborations, principally with Pall
Corporation, a shareholder and our primary research partner. Nevertheless, we
will be required to incur significant expenditures for research, development,
clinical testing and regulatory compliance activities for both our INACTINE(TM)
and affinity purification products.

We will need additional capital in the future, but our access to such capital is
uncertain.

          Our current resources are not sufficient to fund our entire
commercialization efforts, particularly after our divestiture of our plasma
operations which historically generated most of our revenues other than our
partner research funding. Our future capital needs will depend on many factors,
including the successful commercialization of our products, receiving milestone
payments from our collaboration partners, and making progress in our research
and development activities. Our success may also depend on the magnitude and
scope of these activities, the progress and the level of success in our
pre-clinical studies and clinical trials, the costs of preparing, filing,
prosecuting, maintaining and enforcing patent claims and other intellectual
property rights, competing technological and market developments, changes in or
terminations of existing collaboration and licensing arrangements, the
establishment of additional collaboration and licensing arrangements, and the
cost of manufacturing scale-up and development of marketing activities, if
undertaken by us. We do not have committed external sources of funding and we
cannot assure you that we will able to obtain additional funds on acceptable
terms, if at all. If adequate funds are not available, we may be required to:

          .  delay, reduce the scope of or eliminate one or more of our
             development programs;
          .  obtain funds through arrangements with collaboration partners or
             others that may require us to relinquish rights to technologies,
             product candidates or products that we would otherwise seek to
             develop or commercialize ourselves; or
          .  license rights to technologies, product candidates or products on
             terms that are less favorable to us than might otherwise be
             available.

                                       22

<PAGE>

          If we raise additional funds by issuing additional stock, further
dilution to our stockholders may result, and new investors could have rights
superior to existing stockholders. If funding is insufficient at any time in the
future, we may be unable to develop or commercialize our products, take
advantage of business opportunities or respond to competitive pressures.

Our products are and will continue to be subject to extensive government
regulation which may prevent the commercialization of our products and services.

          Our products are and will continue to be subject to extensive
regulation by the federal government, principally the FDA, and state, local and
non-United States governments. Such regulations are wide-ranging and govern,
among other things:

          .  development;
          .  testing;
          .  pre-market clearance or approval;
          .  manufacturing;
          .  labeling;
          .  storage;
          .  advertising and promotion;
          .  sales and distribution; and
          .  use standards and documentation.

          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-United States regulatory
agencies, typically takes several years, depending upon the type, complexity,
novelty and intended purpose of the product. We may encounter significant delays
or excessive costs in our efforts to secure necessary approvals or licenses, or
we may not be successful at all.

          The regulatory process includes pre-clinical (animal) studies and
clinical (human) trials of each product to establish its safety and efficacy.
Even if our products receive approval for commercial sale, their manufacturing,
storage, marketing and distribution will be subject to continuing FDA and other
regulatory requirements. The failure to comply with these regulatory
requirements could result in enforcement action, including, without limitation,
withdrawal of approval, which would harm our business. Later discovery of
problems with our product may result in additional restriction on the product,
including withdrawal of the product from the market. Regulatory authorities may
also require post-marketing testing, which can involve significant expense.

          Distribution of our products and systems outside the United States
will also be subject to extensive governmental regulation. These regulations,
including the requirements for approval or clearance to market, the time
required for regulatory review and the sanctions imposed for violations, vary by
country. Failure to obtain necessary regulatory approvals or any other failure
to comply with regulatory requirements could result in reduced revenue and
earnings.

          Additionally, governments may impose new regulations, which could
further delay or preclude regulatory approval of our products or result in
significantly increased compliance costs. We cannot predict the impact of
adverse governmental regulation, which might arise from future legislative or
administrative action.

          In addition to the regulatory requirements applicable to us and our
products and systems, there are regulatory requirements applicable to our
prospective customers, the blood banks that process and distribute both blood
and blood products. Blood banks such as the American Red Cross and the New York
Blood Center will be required to obtain approved license supplements from the
FDA before using products processed with our pathogen reduction systems. FDA
delays in approving these supplements may deter some blood centers from using
our products. In addition, blood centers that do submit supplements may face
disapproval or delays in approval that could in turn provide further delay or
deter them from using our products.

If our pre-clinical and clinical trials are not successful, we will be unable to
commercialize our products and generate revenue.

          We must provide the FDA and foreign regulatory authorities with
pre-clinical and clinical data that demonstrate our products are safe and
effective before they can be approved for commercial sale. Our lead product,
INACTINE (TM) red blood cell system, recently covered a Phase II clinical trial
in the United States and we are awaiting FDA approval to commence Phase III
clinical trials. The results from pre-clinical studies and early clinical trials
conducted by us will not ensure that results obtained in later clinical trials
will be satisfactory to the FDA or foreign regulatory authorities. Data obtained
from pre-clinical and clinical activities are susceptible to varying
interpretations, which could delay, limit or prevent regulatory approval. Our
completion of

                                       23

<PAGE>

clinical trials may also be delayed by slower than anticipated patient
enrollment, negative or inconclusive clinical results or other adverse events
occurring during the clinical trials. Therefore, we cannot ensure that clinical
trials will demonstrate sufficient safety and efficacy to obtain required
marketing approvals on a timely basis, if at all.

          Our clinical development plan for cellular products, including
INACTINE (TM), assumes that only data from laboratory studies, not from human
clinical trials, will be required to demonstrate efficacy in reducing pathogens
and that clinical trials for these products will instead focus on demonstrating
therapeutic efficacy, safety and tolerability of treated blood components.
Although we have held discussions with the FDA concerning the proposed clinical
plan for these products, this plan of demonstrating safety and efficacy may not
ultimately be acceptable to the FDA or the FDA may reconsider any decision that
this clinical plan is appropriate.

          Our product development costs will increase if we have delays in our
clinical testing or approval from government authorities. Significant clinical
trial delays could impair our ability to commercialize our products and allow
competitors to bring products to market before we do.

Our technologies are new and unproven, and we will need to gain market
acceptance to generate revenue.

          We believe that market acceptance of our products and systems will
depend on our ability to provide acceptable evidence of their safety, efficacy
and cost-effectiveness. Our products will be priced significantly higher than
the corresponding non-virally inactivated products. We believe that market
acceptance of our products and systems will also depend upon the extent to which
physicians, patients and health care payers perceive that the benefits of using
our products and systems justify the additional costs and processing
requirements. Our products and systems may not 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. If
our products and systems fail to achieve market acceptance, we may never become
profitable.

Third-party reimbursement policies may adversely affect our ability to
commercialize and sell our products and services.

          Our ability to successfully commercialize our products depends in part
on the extent to which appropriate levels of reimbursement for our products and
related treatments are obtained from government authorities, private health
insurers, third party payers, and other organizations such as managed care
organizations, or MCOs. Any failure by doctors, hospitals and other users of our
products or systems to obtain appropriate levels of reimbursement could
adversely affect our ability to sell these products and systems.

          Significant uncertainty exists about the reimbursement status of newly
approved medical products and services. Reimbursement in the United States or
foreign countries may not be available for any of our products, reimbursement
granted may not be maintained, and limits on reimbursement available from
third-party payers may reduce the demand for, or negatively affect the price of,
our products. We anticipate that we will need to work with a variety of
organizations to lobby government agencies for improved reimbursement policies
for our products. However, we cannot guarantee that such lobbying efforts will
take place or that they will ultimately be successful.

If we fail to establish and maintain relationships with strategic collaborators
and distributors, we may be unable to market our products.

          We are dependent on strategic collaborators for sales, marketing and
distribution support and for financial support in the development of certain of
our products. If we fail to maintain existing strategic alliances and to secure
new alliances, the failure will delay or possibly inhibit the commercialization
of our products.

          In addition, we may need to seek new collaborators or alliances to
sell and distribute future products or to establish direct commercialization
capabilities. For example, in order to effectively market our products outside
the United States, we may need to secure foreign marketing partners who have a
strong presence in such foreign markets. Securing new corporate collaborators is
a time-consuming process, and we cannot guarantee that the negotiations with new
collaborators will yield positive results. Even if we find additional corporate
collaborators to assist in the commercialization of existing or new product
candidates, the terms of the arrangements may not be favorable or acceptable to
us.

                                       24

<PAGE>

We rely on Pall Corporation for development funding and, in the future, may rely
on Pall Corporation for marketing and sales.

         We have a development and commercialization agreement with Pall
Corporation ("Pall") for red blood cell and platelet pathogen reduction. Under
this agreement, Pall acquired exclusive worldwide marketing rights and is
required to make financial contributions to our development and clinical costs.
As of December 29, 2001, Pall owned approximately 10 percent of our outstanding
shares.

         If Pall fails to provide adequate funding to support our product
development efforts, we will need to obtain additional funding from other
sources. We cannot assure you that we will be able to secure funding on
reasonable terms or at all.

         We do not have our own marketing and sales organization. We plan to
rely on Pall to market and sell the INACTINE(TM) system. If our joint
development agreement with Pall is terminated or if Pall is unable to market the
products successfully, we will be required to find another marketing, sales and
distribution partner or develop these capabilities ourselves. We may not be able
to find a suitable partner on favorable terms or on a timely basis, if at all.
Developing marketing, sales and distribution capabilities ourselves could delay
commercialization of our pathogen reduction systems and increase our costs.

We rely on Haemonetics Corporation to manufacture a cell washing system and
certain disposables as part of the INACTINE(TM) pathogen reduction system.

The procedure for inactivating pathogens using the INACTINE(TM) red blood cell
system requires the use of a cell washing system to remove PEN110, inactivated
pathogens, cell debris and other impurities. We are currently using a cell
washing system manufactured by Haemonetics which we exclusively license from
Haemonetics pursuant to a development and manufacturing agreement. When and if
our INACTINE(TM) system is commercialized, Haemonetics will provide contract
manufacturing services for the cell washing equipment and associated
disposables. If Haemonetics fails to deliver an adequate supply of the cell
washing systems and disposables, we would be required to identify other
third-party manufacturers. We may not be able to identify such manufacturers on
a timely basis or enter into contracts with such manufacturers on reasonable
terms, if at all. Any delay in the availability of the cell washing system and
the disposables from Haemonetics could delay commercialization and subsequent
sales of the INACTINE(TM) system. Furthermore, the inclusion of cell washing
systems manufactured by others could require us to seek new approvals from
governmental regulatory authorities, which could result in delays in product
delivery. There can be no assurance that we would receive any such required
regulatory approvals.

It is likely that we will depend on a limited number of suppliers to manufacture
our product components.

         A limited number of suppliers manufacture our inactivation compounds
for our use in product development, including clinical trials. Our INACTINE(TM)
red blood cell system uses a small molecule compound known as PEN110 to
inactivate pathogens, and our affinity purification system uses a certain
separation media to isolate and remove specific proteins from blood. We have a
contract with one manufacturer for PEN 110 and may add additional manufacturers
to produce this and other compounds to meet our anticipated commercialization
requirements. If any of these manufacturers cannot produce and deliver these
compounds in the required quantities, to the required standards, or in a timely
manner we may face delays in the commercialization of the INACTINE(TM) red cell
system before we are able to identify alternate or additional manufactures to
meet these requirements.

A small number of customers will determine market acceptance of our products.

         A small number of blood collection centers dominate the market for
INACTINE(TM). In the United States, the American Red Cross collects and
distributes approximately 50 percent of the nation's supply of blood and blood
components. Other major United States blood centers include the New York Blood
Center and United Blood Services, each of which distributes approximately 6
percent of the nation's supply of blood and blood components. In Western Europe
and Japan, various national blood transfusion services or Red Cross
organizations collect, store and distribute virtually all of their respective
nations' blood and blood components supply. Failure to properly market, price or
sell our products to any of these large customers could significantly diminish
potential product revenue.

If we do not successfully distinguish and commercialize our technology, we may
be unable to compete successfully or to generate revenue significant to sustain
our operations.

         The biotechnology industry, including the fields of transfusion
medicine and therapeutic use of blood products, is highly competitive and
subject to significant and rapid technological change. Accordingly, our success
will depend, in part, on our ability to respond quickly to such change through
the development and introduction of new products and systems.

         Many of our competitors or potential competitors have substantially
greater financial and other resources than we have and may also have greater
experience in conducting pre-clinical studies, clinical trials and other
regulatory approval procedures as well as in marketing their products. If we or
our corporate partners commence commercial product sales, we or our corporate
partners will be competing against companies with greater marketing and
manufacturing capabilities. Our competitors may obtain patent protection,
receive FDA approval or commercialize products before we do.

         Our ability to compete successfully against currently existing and
future alternatives to our pathogen reduction technology and competitors who
compete directly with us in the pathogen reduction industry will depend, in
part, on our ability to:

         . attract and retain skilled scientific and research personnel;
         . develop technologically superior products;
         . develop competitively priced products;
         . obtain patent or other required regulatory approvals for our
           products;
         . be early entrants to the market; and
         . manufacture, market and sell our products, independently or through
           collaborations.

If we are unable to protect our intellectual property or are unable to operate
our business without infringing intellectual property rights of others, we may
not be able to operate our business profitably.

         Our success depends on our ability to develop proprietary products and
technologies, to obtain and maintain patents, to protect trade secrets, to
operate without infringing upon the proprietary rights of others and to prevent
others from infringing on our proprietary rights. We have exclusive patents,
licenses to patents and patent applications covering critical components of our
technologies. Our patents, pending patent applications and licensed technologies
may not afford adequate protection against competitors, and any pending patent
applications now or hereafter filed by or licensed to us may not result in
patents being issued. In addition, the laws of certain non-United States
countries do not protect 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, we cannot predict with certainty their
enforceability. Our patents or patent applications, if issued, may be
challenged, invalidated or circumvented, or may not provide protection or
competitive advantages against competitors with similar technology. Furthermore,
our competitors may obtain patent protection or other intellectual property
rights for technology similar to ours that could limit our ability to use our
technology or commercialize products that we may develop.

         We are aware that patents have been applied for and/or issued to third
parties claiming technologies for decontamination of blood and blood products
and for prion-binding molecules that may be similar to those needed by us. We
endeavor to follow developments in these fields and we do not believe that our
technologies and/or products infringe upon any proprietary rights of third
parties. To the extent that planned or potential products turn out to be covered
by patents or other intellectual property rights held by third parties, we would
need a license under such patents or other intellectual property rights to
continue development and marketing of our products. Any required licenses may
not be available on acceptable terms, if at all. If we do not obtain such
licenses, we may need to design around other parties' patents or we may not be
able to proceed with the development, manufacture or sale of our products.

         Litigation may be necessary to defend against or assert claims of
infringement, to enforce patents issued to us, to protect trade secrets or
know-how or to determine the scope and validity of the proprietary rights of
others. Litigation or interference proceedings could result in substantial
additional costs and diversion of management focus. If we are ultimately unable
to protect our technology, trade secrets or know-how or are unsuccessful in
defending against claims of infringement, we may be unable to operate
profitably.

         We may rely, in certain circumstances, on trade secrets to protect our
technology. However, trade secrets are difficult to protect. We seek to protect
our proprietary technology and processes, in part, by confidentiality agreements
with our employees

                                       26

<PAGE>

and certain contractors. We cannot be certain that these agreements will not be
breached, that we will have adequate remedies for any breach, or that our trade
secrets will not otherwise become known or be independently discovered by
competitors. In addition, to the extent that our employees, consultants or
contractors use intellectual property owned by others, disputes may arise as to
the rights related to or resulting from the know-how and inventions.

If we lose or are unable to hire and retain qualified personnel, we may not be
able to develop our products and technology.

         We are highly dependent on the members of our scientific and management
staff. We may not be able to attract and retain personnel on acceptable terms,
given the competition for such personnel among other companies and research and
academic institutions. If we lose an executive officer or a significant number
of any of our research and development staff or are unable to hire and retain
qualified personnel, then our ability to develop and commercialize our products
and technology may be hindered.

We use and generate hazardous materials in our business and any claims relating
to the improper handling, storage, release or disposal of these materials could
be time consuming and expensive.

         We are 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. There can be no assurance that we will not be required to
incur significant costs to comply with environmental and health and safety
regulations in the future. Our research and development involves the controlled
use of hazardous materials, including certain hazardous chemicals, viruses and
radioactive materials. Although we believe that our 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, we
could be held liable for any damages that result and any such liability could
exceed our resources.

We may have significant product liability exposure.

         We face exposure to product liability and other claims if our products
are alleged to have caused harm. These risks are inherent in clinical trials and
in the testing, manufacturing, and marketing of human blood products. Although
we currently maintain product liability insurance, such insurance may not be
adequate and we may not be able to obtain adequate insurance coverage in the
future at a reasonable cost. Our inability to obtain product liability insurance
at an acceptable cost or to otherwise protect against potential product
liability claims could prevent or inhibit the commercialization of any products
that we or our partners develop and otherwise have a material adverse effect on
our business.

Our stock price is volatile and you may not be able to resell your shares at or
above the price you paid for them.

         We first publicly issued common stock on June 11, 1998 at $12.00 per
share in our initial public offering. Between June 11, 1998 and December 29,
2001 the closing sale price has ranged from a high of $17.63 per share to a low
of $3.88 per share. The market price of our common stock could continue to
fluctuate substantially due to a variety of factors, including:

         . quarterly fluctuations in results of operations;
         . the announcement of new products or services by us or competitors;
         . changes in or failure to meet earnings estimates by securities
           analysts;
         . sales of common stock by existing shareholders or the perception that
           these sales may occur;
         . adverse judgments or settlements obligating us to pay damages;
         . negative publicity;
         . loss of key personnel;
         . developments concerning proprietary rights, including patents and
           litigation matters; and
         . regulatory developments in both United States and foreign countries.

         In addition, overall stock market volatility has often significantly
affected the market prices of securities for reasons unrelated to a company's
operating performance. In the past, securities class action litigation has often
been commenced against companies that have experienced periods of volatility in
the price of their stock. Securities litigation initiated against us could cause
us to incur substantial costs and could lead to the diversion of management's
attention and resources, which could have a material adverse effect on our
revenue and earnings.

The sale of a substantial number of shares of our common stock could cause the
market price of our common stock to decline.

                                       27

<PAGE>

        Our executive officers, directors and certain large shareholders
collectively beneficially own approximately 64 percent of the outstanding common
stock. Sale, or the availability for sale, of shares of common stock by these or
other shareholders could cause the market price of our common stock to decline.
In addition, approximately 1,182,000 shares of common stock issuable upon
exercise of vested stock options would be currently available for immediate
resale.

Our largest shareholder, Ampersand Ventures, owns sufficient shares of our
common stock to significantly affect the results of any shareholder vote.

        Ampersand Ventures owns beneficially or controls approximately 34
percent of our common stock. Certain matters which, under our restated
Certificate of Incorporation, require a 66 2/3 percent vote
by the shareholders for approval may be delayed or blocked solely by Ampersand
Ventures. These matters include the election of the board of directors,
amendments to our organizational documents, or approval of any merger, sale of
assets or other major corporate transaction.

        In addition, our executive officers and directors, including those
directors representing Ampersand Ventures, beneficially own approximately 64
percent of our common stock. As a result, these executive officers and directors
as a group have the ability to significantly influence the outcome of matters
requiring a shareholder vote.

Item 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our earnings and cash flows are subject to fluctuations due to the effects of
changes in interest rates on our investments of available cash balances in money
market funds and in portfolios of investment grade corporate and U.S. government
securities. Under our current policies, we do not use interest rate derivative
instruments to manage exposure to interest rate changes.

                         REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Stockholders of V.I. Technologies, Inc.:

We have audited the accompanying consolidated balance sheets of V.I.
Technologies, Inc. as of December 29, 2001 and December 30, 2000 and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the years in the three-year period ended December 29, 2001. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of V.I. Technologies,
Inc. as of December 29, 2001 and December 30, 2000 and the results of their
operations and their cash flows for each of the years in the three-year period
ended December 29, 2001, in conformity with accounting principles generally
accepted in the United States of America.

                   Notes to Consolidated Financial Statements
            December 29, 2001, December 30, 2000 and January 1, 2000

1.   Organization and Business Overview

V.I. Technologies, Inc. ("VITEX" or the "Company"), a biotechnology company
headquartered in Watertown, Massachusetts, is developing products designed to
improve the safety of the world's blood supply. The Company's INACTINE(TM)
technology is designed to inactivate a wide range of known and as-yet-unknown
viruses, bacteria and parasites, and has demonstrated its ability to remove
prions, while preserving the therapeutic properties of red blood cells. The
technology works by binding to the RNA or DNA of the pathogen. Once bound, the
compound forms an irreversible bond to the pathogenic nucleic acid preventing
replication and thereby "killing" the pathogen. The Company's lead product is
INACTINE(TM) pathogen reduction of red blood cells. Efforts are underway to
demonstrate the system's success in three areas necessary for commercial
viability: broad pathogen kill, a wide safety margin for the patient, and
minimal interference with the function of the red cell. The Company currently
has collaborations with Pall Corporation, Haemonetics Corporation, and Amersham
Pharmacia Biotech to support commercialization of the INACTINE(TM) portfolio of
products. In collaboration with Oxford University, VITEX is developing a
diagnostic test for pathogenic prions using aptamer technology.

The Company operates in a single reportable segment: blood products. These
products are used in the health care industry and are regulated in the United
States by the U.S. Food and Drug Administration.

The Company has an accumulated deficit of $108.8 million as of December 29,
2001. Management expects to continue to incur operating losses as the Company
pursues its research and development programs. The Company has historically
financed its research and development efforts through the sale of common stock
and through partner research funding. Prior to the August 2001 divestiture, the
Company's Plasma Operations also contributed to funding research and
development.

The Company faces certain risk and uncertainties similar to other biotechnology
companies including the future profitability of the Company; its ability to
obtain additional funding; protection of patents and property rights;
uncertainties regarding the development of the Company's technologies;
competition and technological change; governmental regulations including the
need for product approvals; and attracting and retaining key officers and
employees.

The Company prepares its financial statements on the basis of a 52-week fiscal
year ending on the Saturday closest to the end of the calendar year. In the
notes to the accompanying financial statements, the years ended December 29,
2001, December 30, 2000 and January 1, 2000 are referred to as fiscal years
2001, 2000 and 1999, respectively.

2.   Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the financial statements of the
Company and its wholly owned subsidiary, V.I.Technologies Ltd., an entity
incorporated for regulatory purposes in the United Kingdom. All intercompany
balances and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosures of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
Significant estimates made by the Company include the useful lives of fixed
assets and intangible assets, the recoverability of long-term assets and the
collectibility of other receivables.

Cash and Cash Equivalents

The Company considers all highly liquid investments with maturities under three
months at the time of purchase to be cash equivalents. Cash equivalents
principally consist of money market funds invested in a portfolio of investment
grade, corporate and U.S. government obligations all of which are carried at
market value. As of December 29, 2001 and December 30, 2000, cash equivalents
amounted to $20.8 million and $7.4 million, respectively. Included in the cash
and cash equivalent balances at December 29, 2001 is restricted cash of $0.6
million for letters of credit on leased facilities.

Short-term Investments

Short-term investments consist of investments with maturities between three
months to one year at the time of purchase. These short-term investments consist
of a portfolio of investment grade, corporate and U.S. governmental obligations
all of which are carried at market value.

Inventory

Costs incurred in processing by the Company's Plasma Operations were included in
inventory and expensed upon recognition of related revenues. Such costs included
supplies, direct labor and processing overheads. The plasma itself was supplied
and owned by the Company's customers and, as such, was not included in
inventory. Inventory was stated at the lower of cost, as determined using the
average cost method, or net realizable value. At December 30, 2000, certain
inventory was classified as long term, as it was not expected to be used in
manufacturing in the next fiscal year. Inventory at December 30, 2000 was
comprised of work-in-process of $0.5 million, supplies of $1.0 million, and
short-term and long-term resins of $1.6 million.

Property, Plant and Equipment

Property, plant and equipment are stated at cost and depreciated on a
straight-line basis over the estimated useful lives of the respective assets.
These range from seven to twenty five years for building and manufacturing
equipment, and three to five years for all other tangible assets.

Long-lived Assets

The Company reviews its long-lived assets (property, plant and equipment) for
impairment whenever events of circumstances indicate that the carrying amount of
an asset may not be recoverable. If the sum of the expected cash flows,
undiscounted and without interest, is less than the carrying amount of the
asset, an impairment loss is recognized as the amount by which the carrying
amount of the asset exceeds its fair value.

Intangible Assets

Intangible assets principally consist of core technology and work force acquired
in the Pentose merger (see note 4). Core technology is being amortized on a
straight-line basis over 15 years, and work force is being amortized on a
straight-line basis over 5 years. Periodically, the Company reviews the
recoverability of its intangible assets. The measurement of possible impairment
is based primarily on the ability to recover the balance of the intangible
assets from expected future operating cash flows on an undiscounted basis.
Accumulated amortization relating to intangible assets amounted to $0.7 million
and $0.4 million, at December 29, 2001 and December 30, 2000. Amortization
expense amounted to $0.4 million for fiscal years 2001 and 2000.

Revenue Recognition

Revenue earned by the Company's Plasma Operations was recognized in the period
in which the processing services were rendered and upon satisfaction of certain
quality control requirements. It was not subject to repayment or future
performance obligations.

Processing revenue was derived from providing services to Bayer Corporation and
to the American National Red Cross. Bayer and the Red Cross contributed 89% and
11%, respectively, of total processing revenue in fiscal 2001 prior to the
Plasma Operations divestiture described in note 3. In fiscal 2000, the
composition of revenues was 61% and 29% for Bayer Corporation and the American
National Red Cross, respectively. Processing revenues to Bayer Corporation and
the American National Red Cross each amounted to approximately 45% of total
revenue, excluding the American National Red Cross sales incentive charge (see
note 12) for fiscal year 1999. At December 30, 2000, amounts owed from Bayer and
the American National Red Cross amounted to 24% of net trade receivables.

Research and Development

All research and development costs are charged to operations as incurred.
Reimbursement from collaborators under research programs is recorded within
partner research funding when eligible costs are incurred. Pall Corporation's
reimbursement of costs of the Company's red blood cell program, net of program
costs incurred by Pall, totaled $5.8 million, $3.9 million and $1.8 million in
fiscal years 2001, 2000 and 1999, respectively. Also included within partner
research funding is amortized revenue related to non-refundable up-front and
milestone payments of Amersham Pharmacia Biotech which are amortized over the
life of the related agreement. These amounts totaled $0.2 million and $0.1
million in fiscal 2001 and 2000, respectively. (see note 12)

Income Taxes

Deferred tax assets and liabilities are recognized for the estimated future tax
consequences attributable to differences between the amounts of existing assets
and liabilities carried on the consolidated financial statements and their
respective tax bases and the benefits arising from the realization of operating
loss and tax credit carry-forwards. Deferred tax assets and liabilities are
measured using tax rates in effect for the year in which those temporary
differences are expected to be recovered or settled. A valuation allowance is
established when necessary to reduce deferred tax assets to the amount expected
to be realized.

Net Loss Per Share

Basic net loss per share is computed by dividing the net loss by the weighted
average number of common shares outstanding. Diluted net loss per share is the
same as basic net loss per share since the inclusion of potential common stock
equivalents (stock options and warrants) in the computation would be
anti-dilutive. The dilutive effect of common stock equivalents for the years
2001, 2000 and 1999, had they been included in the computation, would have been
approximately 211,000, 365,000 and 714,000, respectively.

Fair Values of Financial Instruments

The fair values of the Company's capital lease obligations are estimated using
discounted cash flow analyses, based upon the Company's estimated incremental
borrowing rate for similar types of securities (see note 8). For all other
financial instruments, the carrying value approximates fair value due to the
short maturity or variable interest rate applicable to such instrument.

Stock-Based Compensation

The Company accounts for stock-based compensation arrangements in accordance
with the provisions of Accounting Principle Board Opinion No. 25, "Accounting
for Stock Issued to Employees" ("APB No. 25") and complies with the disclosure
provisions of Statement of Financial Accounting Standards ("SFAS") No. 123
"Accounting for Stock-Based Compensation". Under APB No. 25, compensation cost
is recognized based on the difference, if any on the date of grant between the
fair value of the Company's stock and the amount an employee must pay to acquire
the stock. All stock options issued to-date have been granted at the fair market
value of the stock on the respective grant dates. Equity instruments issued to
non-employees are accounted for in accordance with the provisions of SFAS No.
123 and EITF 96-18, "Accounting for Equity Instruments That Are Issued to Other
Than Employees for Acquiring, or in Conjunction with Selling Goods or Services."

Comprehensive Income (Loss)

The Company adopted SFAS No. 130 "Reporting Comprehensive Income", which
requires that all components of comprehensive income (loss) be reported in the
consolidated financial statements in the period in which they are recognized.
For all periods reported, the Company's comprehensive loss is equal to its net
loss reported in the accompanying consolidated statements of operations.

New Accounting Pronouncements

In June 2001, the Financial Accounting Standards Board issued SFAS No. 141,
"Business Combinations" ("SFAS 141"), and SFAS No. 142, "Goodwill And Other
Intangible Assets" ("SFAS 142"). SFAS 141 addresses the accounting for
acquisitions of businesses and is effective for acquisitions occurring on or
after July 1, 2001. SFAS 142 addresses the method of identifying and measuring
goodwill and other intangible assets acquired in a business combination,
eliminates further amortization of goodwill, and requires periodic evaluations
of impairment of goodwill balances. SFAS No. 142 is effective for fiscal years
beginning after December 15, 2001. The Company amortized $0.4 million of
intangible assets during fiscal year 2001 and 2000. The Company is currently
assessing the impacts of adoption of SFAS 141 and SFAS 142.

Statement of Financial Accounting Standards No. 143, "Accounting For Asset
Retirement Obligations", ("SFAS 143"), issued in June 2001, addresses financial
accounting and reporting for obligations associated with the retirement of
tangible long-lived assets and for the associated retirement costs. SFAS 143
which applies to all entities that have a legal obligation associated with the
retirement of a tangible long-lived asset is effective for fiscal years
beginning after June 15, 2002. The Company does not expect the implementation of
SFAS 143 to have a material impact on its financial condition or results of
operations.

Statement of Financial Accounting Standards No. 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets", ("SFAS 144"), issued in August
2001, addresses financial accounting and reporting for the impairment or
disposal of long-lived assets. SFAS 144, which applies to all entities, is
effective for fiscal years beginning after December 15, 2001. The Company does
not expect the implementation of SFAS 144 to have a material impact on its
financial condition or results of operations.

3.   Plasma Operations Divestiture

On August 14, 2001, the Company completed the divestiture of its Plasma
Operations located in Melville, New York to Precision Pharma Services, Inc.
("Precision"). Precision is a newly-formed company owned by management of the
Plasma Operations and Ampersand Ventures ("Ampersand"), a VITEX shareholder (see
note 9). These operations were responsible for producing intermediate plasma
fractions for Bayer and for viral inactivation of transfusion plasma for the Red
Cross. The Plasma Operations accounted for all of the Company's previously
reported processing revenues. The total value of the transaction was
approximately $34.0 million. Prior to the closing of the transaction, the
Company obtained a fairness opinion from an investment banker that the
transaction was fair to the shareholders of the Company.

Consideration received in exchange for substantially all the assets and
liabilities of the Plasma Operations was as follows, in thousands:

          Cash                                               $30,000
          Liabilities assumed by Precision:
            Capital lease obligations                            880
            Advances from customer                             3,131
                                                             -------
                 Total consideration                         $34,011
                                                             =======

The cash consideration of $30.0 million includes a $3.0 million holdback by
Precision, payable on the second anniversary of the divestiture. The Company
provided customary representations and warranties for the transaction. To the
extent that claims under the representations and warranties exceed certain
levels, Precision has the right to offset such claims against the holdback. The
Company does not expect any such claims. At closing, the Company received $25.0
million and was eligible to receive additional consideration of up to $2.0
million if Precision achieved certain financial goals. These goals were met in
the fourth quarter of 2001 and the $2.0 million contingent consideration was
received from Precision subsequent to year end. The $2.0 million payment is
included in other receivables in the consolidated balance sheet at December 29,
2001.

The Company recorded the Precision $3.0 million holdback at its net present
value of $2.7 million. The advances from customer of $3.1 million at closing
represents a continuing obligation of the Company which Precision is required to
fund at maturity in 2003. The holdback and guaranty are included in other assets
in the consolidated balance sheet at December 29, 2001.

A summary at August 14, 2001 of the net assets as sold to Precision and the
liabilities assumed by Precision is as follows, in thousands:

          Trade receivables                                  $ 2,628
          Inventory                                            3,175
          Property, plant and equipment                       34,312
          Other assets                                           596
                                                             -------
                 Total assets                                 40,711

          Current liabilities, excluding capital lease
            obligations                                        1,565
                                                             -------

          Net assets divested                                $39,146
                                                             =======

Based upon the transaction consideration of $33.7 million, at net present value,
in comparison with the net book value of the assets and liabilities transferred
to Precision of $39.1 million plus transaction-related costs and adjustments of
$1.4 million, the Company recorded a loss of $6.8 million on the divestiture.

The Company has guaranteed the performance of Precision under capital and
operating leases assumed by Precision in the transaction. The aggregate
outstanding payments under these leases totaled $0.8 million at December 29,
2001.

The Company's unaudited pro forma results for fiscal years 2001 and 2000
assuming the divestiture occurred on the first day of fiscal year 2000 are as
follows, in thousands, except for per share data:

                                                   2001        2000

          Net revenues                           $ 6,264     $ 4,030
          Net loss                              ($20,810)   ($18,172)
          Basic and diluted loss per share        ($0.93)     ($0.92)

                                       42

These unaudited pro forma results have been prepared for comparative purposes
only and do not purport to be indicative of the results of operations that
actually would have resulted had the divestiture occurred on the first fiscal
day of 2000 or the future results of operations.

4.   Pentose Merger

On November 12, 1999, the Company completed its merger with Pentose
Pharmaceuticals, Inc., a Delaware corporation ("Pentose"), pursuant to an
Agreement and Plan of Merger and Reorganization dated as of July 28, 1999.
Pentose' principal business involves the development for commercialization of
novel antiviral products for medical use based on innovative applications of
nucleic acid chemistry. Pentose developed the INACTINE(TM) technology platform
for the inactivation of viral pathogens in blood components, for transfusion
plasma derivatives and for biopharmaceuticals. Under the terms of the merger,
6,443,731 shares of common stock of the Company were issued in exchange for all
of the outstanding Pentose common and preferred stock. Following the exchange,
former shareholders of Pentose owned approximately 34% of the outstanding common
stock of VITEX. Each outstanding option and warrant to purchase Pentose common
stock was converted into the right to purchase 0.48937 of a share of VITEX
common stock. A total of approximately 500,000 shares of the Company's common
stock were issuable to option-holders and warrant-holders of Pentose upon
exercise of options and warrants assumed in the merger.

The merger was accounted for under the purchase method of accounting. The
purchase price representing the fair value of the common stock and other direct
acquisition costs of $38.8 million has been allocated to the assets and
liabilities assumed based on fair values at the date of acquisition. The excess
of the fair value of the net assets acquired over the purchase price represented
negative goodwill of approximately $2.0 million which amount was allocated
proportionately to reduce the value of the noncurrent assets acquired and
in-process R&D which was charged to operations. The purchase price was allocated
as follows:

          Cash                                                    $   549,000
          Other current assets and long term deposits                 409,000
          Work force                                                  542,000
          Core technology                                           3,709,000
          In-process R&D                                           32,998,000
          Fixed assets                                                595,000
                                                                  -----------
          Net purchase price                                      $38,802,000
                                                                  ===========

The work force valuation was based upon replacement cost. The valuation of core
technology and in-process R&D was based on estimated future revenues. In-process
R&D was valued by estimating the projected net cash flows related to products
under development, based upon the future revenues to be earned upon
commercialization of such products. The percentage of the cash flow allocated to
purchased in-process research and development was derived from the estimated
percentage completion for each of the projects. These cash flows were discounted
back to their net present value. The resulting projected net cash flows from
such projects reflect management's estimates of revenues and operating profits
related to such projects.

In anticipation of the merger with Pentose, the Company recorded a research and
development charge in 1999 of $2.2 million for severance and other integration
related expenses, including the elimination of duplicate facilities and excess
capacity, operational realignment and related workforce reductions of the
Company's employees and facilities. As a result of the merger, 22 employees were
severed. The charge was substantially paid by December 29, 2001.

7.   Long-Term Debt

The Company was obligated under a credit agreement with a bank for a term loan
in the initial principal amount of $10.8 million. The term loan was secured by
substantially all the assets of the Plasma Operation plant. The term loan bore
interest at the Company's option of either LIBOR plus 2.75% to 1.75% or the base
rate of the bank, as defined, plus margins of up to 0.5%. At December 30, 2000,
the Company was using one month LIBOR (6.64%) plus 2.75%. In connection with the
divestiture of its Plasma Operations in August 2001 (see note 3), the Company
settled all outstanding balances of the term loan.

8.   Capital Lease Obligations

The Company was obligated under a Master Equipment Lease Agreement (the "Master
Lease") under which it borrowed $6.2 million to lease production equipment for
its Plasma Operations plant. The Master Lease contained escalating monthly lease
payments over a five-year period and various options to purchase the equipment.
The effective interest rate was approximately 16.2% per annum. With consent of
the lessor, the Master Lease was transferred to Precision during the Plasma
Operations divestiture (see note 3).

The Company has several capital lease obligations related to laboratory
equipment. Under these leases, the Company has options to purchase the equipment
at prices specified in the agreements. The effective annual interest rates of
the leases approximates 9.3%. Total future minimum payments are as follows:

9.   Stockholders' Equity

Common Stock

On November 12, 1999, the Company and Pentose Pharmaceuticals, Inc., completed a
merger whereby Pentose shareholders received 6,443,731 shares of VITEX common
stock, par value $0.01 per share for all the outstanding common and preferred
shares of Pentose. These shares represented 34% of the outstanding VITEX common
stock after the merger.

On December 6, 1999, the Company reached a performance milestone under its
collaboration agreement with Pall (see note 12). As required under the
agreement, Pall invested $3.0 million for 538,821 shares of the Company's common
stock based on the then current average market price of $5.57 per share.

On December 27, 2000, the Company reached another performance milestone under
its collaboration agreement with Pall. As required under the agreement, Pall
invested $4.0 million for 807,062 shares of the Company's common stock based on
the then current average market price of $4.96 per share.

On March 2, 2001, the Company sold 1,666,667 shares of the Company's common
stock to an outside investor at the then current market price of $6.00 per share
for a total of $10.0 million.

On May 24, 2001, the Company shareholders voted to increase the number of
authorized shares of common stock from 35 million to 45 million.

Ampersand Ventures, the Company's largest shareholder, owns beneficially or
controls approximately 34 percent of the Company's common stock. Certain matters
which, under the restated Certificate of Incorporation, require a 66 2/3 percent
vote by the shareholders for approval may be delayed or blocked solely by
Ampersand Ventures. These matters include the election of the board of
directors, amendments to organizational documents, or approval of any merger,
sale of assets or other major corporate transaction.

Preferred Stock

Preferred stock may be issued from time to time in one or more series, with such
designations, rights, and preferences as shall be determined by the Board of
Directors. No preferred stock was outstanding as of December 29, 2001 or
December 30, 2000.

10.  Stock Plans

Employee Stock Purchase Plan

Under the 1998 Employee Stock Purchase Plan ("the 1998 Purchase Plan"),
employees may purchase shares of common stock at a discount from fair market
value. The 1998 Purchase Plan is intended to qualify as an employee stock
purchase plan within the meaning of Section 423 of the Internal Revenue Code.
Rights to purchase common stock under the 1998 Purchase Plan are granted at the
discretion of the Compensation Committee of the Board of Directors, which
determines the frequency and duration of individual offerings under the 1998
Purchase Plan and the dates when stock may be purchased. Eligible employees
participate voluntarily and may withdraw from any offering at any time before
stock is purchased. Participation terminates automatically upon termination of
employment. The purchase price per share of common stock to the purchaser under
the 1998 Purchase Plan is 85% of the lesser of the Company's common stock fair
market value at the beginning of the offering period or on the applicable
exercise date and may be paid through payroll deductions, periodic lump sum
payments or both. The 1998 Purchase Plan terminates in February 2008. There are
89,445 shares of common stock reserved for issuance under the 1998 Purchase
Plan, of which 19,037 shares and 31,698 shares of common stock were issued
during the years ended December 29, 2001 and December 30, 2000, respectively.
There are 6,587 shares available for future purchase as of December 29, 2001.

Director Stock Option Plan

All of the directors who are not employees of the Company (the "Eligible
Directors") are currently eligible to participate in the Director Stock Option
Plan (the "1998 Director Plan"). Each non-employee who is initially elected to
the Company's Board of Directors shall, upon his initial election by the
Company's stockholders, automatically be entitled to an option to purchase
15,000 shares of common stock. In addition, each Eligible Director will be
entitled to receive an annual option to purchase 2,000 shares

                                       45

of common stock.

The options vest over a four-year period with 25% of the grant vesting after six
months, and 25% vesting at the end of the second, third and fourth year
thereafter, provided that the option-holder is still a director of the Company
at the opening of business on such date. The 1998 Director Plan has a term of
ten years. The exercise price for the options is equal to the last sale price
for the common stock on the business day immediately preceding the date of
grant. The exercise price may be paid in cash or shares. During 2001, the
Company increased the number of shares of common stock reserved for issuance
under the 1998 Director Plan from 150,000 to 250,000, of which 103,000 options
are available for future grants as of December 29, 2001.

Equity Incentive Plans

The Company has 3,000,000 shares of common stock reserved for issuance under the
1998 Equity Incentive Plan (the "1998 Equity Plan") of which 240,661 options are
available for future grants as of December 29, 2001. The 1998 Equity Plan
permits the granting of both incentive stock options and nonstatutory stock
options. The option price of the shares for incentive stock options cannot be
less than the fair market value of such stock at the date of grant. Options are
exercisable over a period determined by the Board of Directors, but not longer
than ten years after the grant date. All stock options issued to-date have been
granted at the fair market value of the stock on the respective grant dates.

In connection with the Pentose merger, the Company adopted the 1999 Supplemental
Stock Option Plan (the "1999 Plan") authorizing the granting of both incentive
and nonstatutory stock options on 1,000,000 shares of common stock reserved
under the plan of which 469,863 options are available for future grants as of
December 29, 2001. The option price of the shares for incentive stock options
cannot be less than the fair market value of such stock at the date of grant or
110% of the fair market value per share if the optionee owns more than 10% of
the total combined voting power of the Company.

Pro forma information regarding net loss and net loss per share for each of the
years in the three year period ended December 29, 2001 was determined as if the
Company had accounted for its stock options using the fair value method
estimated at the date of grant using a Black-Scholes option pricing model with
the following assumptions:

                                    2001             2000           1999
                                    ----             ----           ----
Volatility                            70%              76%           67%
Expected dividend yield                0%               0%            0%
Risk-free interest rate             4.63%            6.38%          6.0%
Expected life                       5 years          5 years        5 years

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility. Because
the Company's stock options have characteristics significantly different from
those of traded options, and because changes in the subjective input assumptions
can materially affect the fair value estimate, in management's opinion, the
existing models do not necessarily provide a reliable single measure of the fair
value of its employee stock options.

For purposes of pro forma disclosures, the estimated fair value of the options
is amortized to expense over the options' vesting period. The Company's pro
forma information is as follows:

At December 29, 2001 and December 30, 2000, a valuation allowance has been
applied to offset the respective deferred tax assets in recognition of the
uncertainty that such tax benefits will be realized. The valuation allowance
increased by $12.4 million in fiscal year 2001 and $7.7 million in fiscal year
2000.

In assessing the realizability of deferred tax assets, management considers
whether it is more likely than not that some portion or all of the deferred tax
assets will not be realized. The ultimate realization of deferred tax assets is
dependent upon the generation of future taxable income during the periods in
which those temporary differences become deductible. Management considers
projected future taxable income and tax planning strategies in making this
assessment. In order to fully realize the deferred tax asset, the Company will
need to generate future taxable income of approximately $85.5 million. At
December 29, 2001, the Company has available net operating loss carry-forwards
for federal and state income tax reporting purposes of approximately $85.5
million, and has available research and development credit carry-forwards for
federal income tax reporting purposes of approximately $2.0 million, which are
available to offset future taxable income, if any. These carry-forwards will
expire beginning in 2010. Deferred tax assets and related valuation allowance of
$0.5 million related to the net operating loss carryforward results from the
exercise of employee stock options, the tax benefit of which, when recognized,
will be accounted for as a credit to additional paid-in-capital rather than a
reduction of income tax expense.

The Company experienced a change in ownership during July 1998, which resulted
in approximately $22.8 million of the Federal net operating loss being subject
to an annual limitation of approximately $7.4 million. In addition, the net
operating loss carryforwards of $85.5 million includes $11.5 million from the
acquisition of Pentose which is subject to an annual limitation of $2.1 million.

12.  Collaborations

Pall Corporation. On February 19, 1998, the Company and Pall Corporation
("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 pathogen reduction 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 products.
Under the Pall Agreements, Pall receives exclusive worldwide distribution rights
to all the

                                       48

<PAGE>

Company's systems incorporating pathogen reduction technology for red blood
cells and platelets. The parties have also agreed to equally 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. Pall reimburses the Company for fifty percent of excess of
the Company's red cell program research costs over those costs incurred directly
by Pall. Total reimbursement by Pall was $5.8 million, $3.9 million and $1.8
million during fiscal years 2001, 2000 and 1999, respectively. Eligible research
costs under this collaboration were approximately $11.6 million, $7.8 million
and $3.6 million during fiscal years 2001, 2000 and 1999, respectively. Partner
research funding included within other receivables on the consolidated balance
sheets at fiscal year end 2001 and 2000 amounts to $0.5 million and $0.6
million, respectively.

Upon execution of the Pall Agreements and at the time of the Company's initial
public offering, Pall made equity investments in VITEX totaling $9.0 million. In
addition, the Pall Agreements provide that Pall will purchase up to $17.0
million worth of the Company's common stock in installments tied to the
achievement of specified development milestones ($10.0 million remaining at
December 29, 2001). Such equity investments by Pall will be made at the
prevailing market price per share. The Company reached equity milestones in
December 2000 and December 1999 and, accordingly, Pall purchased $4.0 million
and $3.0 million, respectively, of the Company's common stock at the then market
price. Certain of the Pall Agreements may be terminated in certain circumstances
including an event of default by either party. As of December 29, 2001, Pall
owned approximately 10% of the Company's outstanding shares.

Amersham Pharmacia Biotech. On April 6, 2000, the Company entered into a
ten-year worldwide license and distribution agreement with Amersham Pharmacia
Biotech ("APBiotech"), the life science business of Nycomed Amersham plc. Under
the agreement APBiotech will exclusively market and distribute the Company's
INACTINETM pathogen reduction technology to manufacturers of biopharmaceuticals
and transgenic products and to plasma fractionators. VITEX retains rights for
the marketing and distribution of the technology in all other areas including
blood components such as red cells, platelets and plasma.

Under the terms of the agreement, the Company received non-refundable up-front
payments and milestone payments totaling $1.5 million in fiscal 2000 and could
also receive further payments of $1.0 million subject to certain product testing
and FDA approval milestones. In addition, the Company will receive a percentage
royalty based on net sales made by APBiotech which incorporate the INACTINETM
technology. The Company will provide APBiotech with technical support, training
and conduct research and development projects as directed by APBiotech during
the ten-year term of the agreement. In accordance with SAB 101, the payments
will be recognized from the date of receipt of the payments through the end of
the term of the agreement or approximately ten years. For the fiscal year 2001
and 2000, the Company recognized revenue of $0.2 million and $0.1 million from
the amortization of these payments, which is recorded within partner research
funding on the consolidated statements of operations. The balance of $1.3
million is reflected as deferred revenue in the consolidated balance sheet as of
December 29, 2001.

Plasma Operations

Prior to the divestiture of its Plasma Operations (see Note 3), the Company
maintained commercial relationships with two principal customers: Bayer
Corporation ("Bayer") and the American National Red Cross (the Red Cross). The
Company processed Bayer plasma into intermediate plasma derivatives and returned
these products for further manufacturing within Bayer's production facilities.
Commercial terms were documented in the 1995 Agreement for Custom Processing
(the "Processing Agreement") which, with amendments extended to 2003. This
Processing Agreement was assigned to Precision in the Plasma Operations
divestiture. In fiscal year 1999, the Company collected a $3.5 million insurance
settlement related to a claim for losses incurred during processing of Bayer
plasma in fiscal year 1998.

The Company also processed plasma for the Red Cross into virally inactivated
transfusion plasma which was marketed by the Red Cross under the brand,
PLAS+(R)SD. Commercial terms were documented in the 1997 Supply, Manufacturing,
and Distribution Agreement (the "Agreement"). Prior to the divestiture of the
Plasma Operations, the Company exercised its rights to terminate the Agreement
in June 2001 in order to allow Precision to negotiate a new arrangement.

In fiscal year 1999, the Company recorded a charge of $4.5 million for the
estimated costs of a PLAS+(R)SD Sales Incentive Program. The program was
terminated early and, in fiscal 2000, the Company recorded a credit of $1.2
million representing unused sales incentives.

Under a previous collaboration agreement, the Red Cross had made a total of $3.0
million non-interest bearing, unsecured advances. The original terms were
subsequently amended and the Company discounted the advance to its net present
value using an interest rate of 7.75%. As part an amendment to the Agreement in
fiscal 2000, certain sales incentives earned by the Red Cross of approximately
$0.5 million were added to the outstanding Red Cross advance, increasing the
balance to $3.5 million due in 2003. This new balance was discounted to net
present value using an interest rate of 8.0%. This resulted in a gain of $.4
million, which was recorded in 2000. The Red Cross advances remain obligations
of the Company, subject to a funding guarantee by Precision as described in note
3.

13.  Charge Related to Product Recall

On April 16, 1999, the Company initiated a voluntary recall of certain lots of
PLAS+(R)SD, which were found to contain a heightened presence of parvovirus B19.
This recall, which was a precautionary measure, was completed on May 12, 1999.
In the accompanying consolidated statements of operations for fiscal year 1999,
the charge related to product recall of $2.6 million includes the write-off of
inventory lots with heightened levels of parvovirus B19, production testing,
other direct recall expenses and a reserve for an equitable sharing of recall
costs incurred by the Red Cross. Costs associated with idle production
facilities during the recall period, in the amount of $0.3 million, are included
in cost of sales.

14.  Other Related-Party Transactions

License Agreements

The Company was spun-off from the New York Blood Center, Inc. ("NYBC") in 1995.
Under terms of the spin-off, NYBC transferred to the Company various net assets
including the Plasma Operations plant in Melville, New York, related operating
and product licenses and certain other tangible and intangible assets,. The
Company also became the licensee of a 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. In
anticipation of the Plasma Operations divestiture (note 3), the Company
terminated the last active license from NYBC, the license to SD viral
inactivation technology. Under the license agreements, the Company was required
to pay royalties to the NYBC on revenues derived from their use. In fiscal years
2001, 2000 and 1999, total payments to NYBC were $0.7 million, $1.4 million, and
$1.7 million, respectively. Also, in fiscal 2000 the Company agreed to
financially support NYBC marketing efforts for PLAS+(R)SD and made payments
totaling $0.4 million under the agreement.

Other Services

In fiscal years 2000 and 1999, the Company received NYBC payments of $46,000 and
$45,000, respectively, for scientific research. These amounts were recorded as
partner research funding in the accompanying consolidated statements of
operations.

The Company purchased $0.2 million, $0.4 million and $0.8 million of production
related materials and supplies from Pall for the fiscal years 2001, 2000 and
1999, respectively.

The Company has an arrangement for scientific consulting services with its
Chairman. Under terms of the agreement, the Company paid $0.1 million and $0.03
million in fiscal 2001 and 2000, respectively. During fiscal 2001, the Company
purchased $0.1 million in processing services from a company in which the
Chairman is an officer and an investor and Ampersand is also an investor.

17. Commitments and Contingencies

Lease Commitments

Future minimum lease payments under non-cancelable operating leases at December
29, 2001 are as follows:

                    2002                          $1,011,000
                    2003                           1,104,000
                    2004                           1,104,000
                    2005                           1,121,000
                    2006                           1,121,000
                    Thereafter                     2,266,000

The Company leases its office facilities and certain equipment under
non-cancelable operating leases that expire at various dates through 2009. Rent
expense was approximately $1.0 million, $0.9 million and $0.4 million for fiscal
year 2001, 2000 and 1999, respectively.

The Company has guaranteed the performance of Precision under capital leases
obligations assumed by Precision in the divestiture (see note 3). The aggregate
outstanding payments under these leases totaled approximately $0.8 million at
December 29, 2001.

Ethanol Usage Tax

        The Company used ethanol within its Plasma Operations as a concentration
agent in its plasma fractionation process and in column regeneration for the
PLAS+(R)SD process. Ethanol had been purchased by the Company on the assumption
that it is entitled to tax-exempt status based on operations and usage in
manufacturing. An application to formalize tax-exempt status has been pending
before the U.S. Bureau of Alcohol, Tobacco and Firearms (the "Bureau") since
1998. The Bureau initiated its review in 2000 and requested the Company to pay
ethanol excise tax until a determination is made. On advice of counsel, the
Company commenced paying the excise tax in October 2000 while the review is in
process.

        In the event of a determination that the Company is not eligible for tax
exemption, the Bureau advised the Company that it would be entitled to a
drawback arrangement for alcohol usage. During fiscal year 2001, the Company
recovered from the Bureau $2.3 million in drawback claims related to plasma
fractionation. The Bureau has disallowed drawback on the PLAS+(R)SD process and
the Company is challenging this decision. Due to the uncertainty of securing
drawback rights on PLAS+(R)SD, the Company has fully reserved all
PLAS+(R)SD-related tax deposits. Management continues to pursue tax-exempt
status. In the event the Company is not granted tax exempt status, management
believes that retroactive costs, if any, would not be material to the Company's
financial condition and results of operations.

        Included in other receivables at December 29, 2001 is $0.5 million
representing amounts paid for alcohol excise tax for which the Company has filed
or expects to file drawback claims. Approximately $0.3 million was collected
subsequent to year end.
