PART I

Item 1. BUSINESS

HemaSure Inc. (the "Company") was established in December 1993 as a
wholly-owned subsidiary of Sepracor Inc. ("Sepracor"). Prior to that date, its
business was conducted as part of Sepracor's bioprocessing division. Effective
as of January 1, 1994, in exchange for 3,000,000 shares of common stock, par
value $.01 per share (the "Common Stock"), of the Company, Sepracor transferred
to the Company its technology relating to the manufacture, use and sale of
medical devices for the separation and purification of blood, blood products and
blood components and its membrane filter design technologies.

The Company is applying its proprietary filtration and pathogen
inactivation technologies to develop products to increase the safety of donated
blood and to improve certain blood transfusion and collection procedures. The
Company has developed the following products for use by blood centers, hospital
blood banks and hospitals:

o The LeukoNet Pre-Storage Leukoreduction Filtration System (the
"LeukoNet System") is designed to remove harmful leukocytes
(white blood cells) from donated blood.

o The LeukoVir-MB-Filter is designed to remove methylene blue
that has been used to inactivate viruses in blood plasma and
to remove contaminating leukocytes, microaggregates and excess
lipids that may compromise the integrity of plasma.

In addition, the Company is also developing the SteriPath Blood
Pathogen Inactivation System (the "SteriPath System") for use by these blood
centers, hospital blood banks and hospitals. The SteriPath System is designed to
inactivate viruses and other pathogens and remove leukocytes from donated blood.

Industry Background

Individuals suffering physical trauma or anemia, undergoing complex
surgical procedures or hemodialysis or undergoing treatment for cancer are among
the diverse group of patients who require blood transfusions in the course of
their medical care. Health risks, such as transfusion complications and
infections, may arise from contaminated blood and blood products, although
infection risks are lower today than in the recent past as a result of improved
donor education and selection and implementation of screening procedures to
identify certain virus contaminated blood prior to transfusion. Moreover, these
health risks can increase in patients who receive frequent transfusions, such as
those suffering from kidney and liver disorders, and patients who are
immune-suppressed, such as those undergoing treatment for cancer.

The number of units of whole blood, blood components or plasma a
patient receives in a blood transfusion varies significantly. A patient
undergoing routine surgery may typically receive three or four units, while a
cancer patient undergoing platelet transfusion may receive in excess of 100
units over time. The risk of infection to a patient increases as the number of
units transfused increases.


-1-






Transfusion Risks

Health risks from transfusions, including complications and infections,
arise from the presence of leukocytes, viruses and other pathogens in blood,
cellular blood components and plasma. In addition, autologous blood recovery and
reinfusion results in an increased risk of contamination of a patient's blood.

Leukocytes. Leukocytes (white blood cells) may cause adverse reactions
in patients receiving blood transfusions, such as fever, chills, immune system
suppression or development of immunological responses that could cause the
affected patient to reject subsequent blood transfusions. In addition,
leukocytes may harbor infectious viruses, including cytomegalovirus and human
T-cell lymphocyte virus I (HTLV-I). The Company believes that the demand for
filtered blood for transfusions will continue to increase over the next several
years due to the growing recognition in the medical field of the benefits of
leukocyte reduction.

Pathogens. Viruses such as HIV, hepatitis B and hepatitis C may be
contained inside or outside of the leukocytes and may be transmitted during
transfusions. Other viruses may develop or become prevalent over time. Of the
currently known viruses, there has been significant public focus on hepatitis
and HIV.

Other Blood-Borne Pathogens. In addition to viruses, other blood-borne
pathogens may be transmitted by blood transfusions. These include the parasites
which cause malaria and Chagas' disease and the spirochetes which cause syphilis
and Lyme disease. An effective pathogen inactivation system for blood needs to
successfully inactivate a broad range of parasites and spirochetes, in addition
to viruses.

Other Contaminants. During surgical procedures, the walls of red blood
cells can break down and release hemoglobin, the oxygen carrying chemical
component normally contained within red blood cells. In its free form,
hemoglobin is toxic and can result in renal shutdown if present in sufficient
quantities. The contamination of blood by free hemoglobin has limited the use of
reinfusion of recovered blood.

PRODUCTS AND PRODUCTS UNDER DEVELOPMENT

LeukoNet System

The Company's LeukoNet System is designed for leukocyte filtration by
blood centers immediately prior to blood storage, a process which the Company
believes results in improved quality leukocyte reduced blood. The Company
believes that the demand for filtered blood for transfusions will continue to
increase over the next several years and that, while leukocyte filtration
currently takes place primarily at the patient bedside, as the demand for
filtered blood increases, leukocyte removal will shift from bedside filtration
of individual units on an "as needed" basis to centralized filtration performed
at blood centers.

The LeukoNet System is based on a proprietary filter medium comprised
of multiple fibrous components. Leukocytes are removed by a combination of
entrapment and adhesion. With a proprietary automatic internal prime and drain
design, the filter device reduces operator intervention and facilitates

-2-






high volume, centralized processing in a regional blood center environment. The
Company is focusing its marketing efforts exclusively on blood centers for
pre-storage leukocyte reduction.

In December 1994, the Company filed a 510(k) premarket notification
clearance with the United States Food and Drug Administration (the "FDA") for
the LeukoNet System, and in June 1995 the Company received such clearance. The
Company commenced commercialization of the LeukoNet System in the United States
and in foreign countries in the second half of 1995. While the Company believes
that the performance and ease-of-use of the LeukoNet System will compare
favorably with other blood filtration devices, there can be no assurance that
the performance or price of the LeukoNet System will be sufficient to achieve
significant sales, particularly in view of the dominant position in the market
held by Pall Corporation. See "-- Competition."

Sales of the Company's LeukoNet System to the American Red Cross
Biomedical Services accounted for 83% of the Company's total revenues in 1996.

LeukoVir-MB Filter

The Company introduced its LeukoVir-MB Filter in Europe in the second
half of 1996. Developed in collaboration with the German Red Cross of Lower
Saxony and the Swiss Red Cross, the Company's LeukoVir-MB Filter is designed to
remove the virucidal agent methylene blue, which is used to treat plasma for
transfusion. Methylene blue has not been approved for use in the United States.
The LeukoVir-MB Filter, currently awaiting marketing approval in Europe, is
designed to process individual units of plasma by a single, disposable system,
eliminating the potential infection-spreading danger of systems requiring
pooling of many units before processing. The Company believes that the reduction
of this viral inactivation agent to undetectable levels should eliminate
concerns regarding methylene blue's potential toxicity. Additionally, the
LeukoVir-MB Filter is designed to remove contaminating leukocytes and eliminate
microaggregates, bacteria and excess lipids that may compromise the integrity of
plasma.

There can be no assurance that the LeukoVir-MB Filter will achieve
market acceptance.

SteriPath System

Although all blood derivatives in the United States and Europe are
treated to inactivate pathogens with FDA validated procedures or other validated
procedures that employ chemical, filtration or thermal inactivation processes,
the Company believes that, to date, no effective treatment is commercially
available for pathogen inactivation of cellular components of blood. The Company
believes that inactivation of all contaminating viruses and other pathogens in
blood and blood components used for transfusion will require pathogen
inactivation and removal procedures similar in effectiveness to those procedures
used for blood derivatives and that an effective pathogen inactivation system
for blood and blood components must be able to:

o introduce a chemical agent to inactivate blood pathogens without causing
toxicity to the patient or impairing the functionality or viability of the
blood;

o remove the chemical agent from the blood prior to transfusion; and

o remove any virus-containing cellular blood components (leukocytes) in the
transfusion product.

-3-







The Company is developing the SteriPath System as an integrated blood
pathogen inactivation system for use with blood and blood components. The
Company's objective is to design a system that will eliminate infectivity,
without adversely affecting circulatory and functional properties of blood cells
and without generating any new immunologic structures that could react with the
patient's immune system. The Company is designing its SteriPath System to
chemically inactivate viruses and other pathogens present in donated blood and
then remove the inactivating agent and leukocytes through specific filtration.
The Company expects to package the SteriPath System as a closed system to
accommodate the normal blood processing operations at blood centers around the
world.

The Company has developed or licensed several compounds for the
inactivation of viruses and other pathogens and is currently evaluating their
potential use in the SteriPath System. The Company is initially investigating
the chemicals hydroxymethylglycinate (HMG) and formaldehyde as pathogen
inactivation candidates for red blood components, and methylene blue technology
for use in single units of donor plasma. See "-- Technologies -- Pathogen
Inactivation Technologies." The Company filed an Investigational Device
Exemption ("IDE") with the FDA for this product in December 1996. The Company
currently procures HMG from a sole source, but does not have a contractual right
to procure HMG in the future. Should the Company need to procure substantial
quantities of HMG in connection with the development and commercialization of
its SteriPath System, the failure to obtain sufficient quantities of HMG from
the sole source, or to identify additional, suitable sources, could have a
material adverse effect on the Company's ability to develop and commercialize
the SteriPath System.

The process of pathogen inactivation to date is most advanced in the
purification of plasma pharmaceuticals. Although blood derivatives in the United
States and Europe are treated to inactivate pathogens, current methods of plasma
pathogen inactivation involve treatment by filtration, solvents/detergents,
thermal inactivation (pasteurizing) and photochemical treatment with methylene
blue (a method used in parts of Europe). Some of these methods are effective
only for certain classes of pathogens and do not function as broad-spectrum
pathogen inactivation agents.

While the Company believes that its proprietary chemistries offer
promising opportunities for blood pathogen inactivation, there can be no
assurance that the SteriPath System will be successfully developed or achieve
market acceptance.

Other Products of the Company

The Company also has proprietary interests in certain other potential
products or technologies, including: (i) the CellWasher Cell Concentrator
(designed to remove excess fluids from blood prior to reinfusion into patients);
(ii) the HemoNet Filter (a filter which is designed to remove tissue
contaminants and free hemoglobin from recovered blood prior to reinfusion during
surgical procedures); (iii) the Surgical Blood Salvage System (designed to
incorporate the features of both the HemoNet Filter and CellWasher Cell
Concentrator); and (iv) the PlasmaSep Plasma Collection System (a hollow-fiber
filtration-based system designed for the collection of plasma for
fractionation). These products are not currently under active development by the
Company; however, to the extent the Company identifies a suitable third party
development partner with respect to any one or more of such products or
technologies who agrees to share development efforts and costs with the Company,
the Company would pursue further the development and commercialization of such
products and technologies with such third party. There can be no assurance,
however, that the Company will identify or enter into definitive agreements with
any such development partner, or that it will successfully develop the products
or technologies described herein.

-4-







Regulatory Approval

The Company believes that its blood filtration products under
development will be classified as medical devices and that it will be able to
secure regulatory approval in the United States for each of its medical device
products through 510(k) premarket notification clearance with the FDA. In April
1996, the FDA informed the Company that its SteriPath System will be classified
as a device and that the Company will be able to seek to secure regulatory
approval in the United States through an IDE/Premarket Approval Application
("PMA") process. There is no assurance, however, that the FDA will determine
that any of the Company's products will meet the requirements for its expected
classification. If the FDA concludes that any product does not meet such
requirements, then the process for obtaining regulatory approval for such
product in the United States would be significantly lengthened.
See "-- Government Regulation."

Membrane Products

Since its inception in December 1993 through the first quarter of 1996,
the Company manufactured and sold certain non-blood related process-scale
membrane devices used for the separation and purification of certain
pharmaceuticals, chemicals and biologics. See "-- Relationship with Sepracor."
Substantially all of the Company's revenues through the first quarter of 1996
have been attributable to sales of these non-blood related membrane filter
products. Revenues from these products were $13,000, $517,000 and $339,000 in
1996, 1995 and 1994, respectively, and are not expected to continue in any
material respect beyond 1996.

Rhone-Poulenc Rorer Inc. accounted for 18% of the Company's total
revenues with respect to such membrane products in 1994. In 1996, 1995 and 1994,
sales to Sepracor with respect to membrane products accounted for 2%, 57% and
50% of the Company's total revenues, respectively. Revenues from the U.S.
Department of the Army related to such products represented 7%, 36% and 18% of
the Company's revenues in 1996, 1995 and 1994, respectively.

Technologies

The Company's current products are based on its proprietary
technologies in the areas of pathogen inactivation, affinity separations,
organic chemical synthesis, membrane technology and device design and
fabrication.

Pathogen Inactivation Technologies

The Company's proprietary pathogen inactivation chemistries are
designed to react with the nucleic acid of various pathogens, thereby
effectively eliminating disease transmission from pathogen infected blood and
blood products. The Company is developing chemical compounds and process
conditions to minimize deleterious changes in the blood product due to the
addition and subsequent removal of such additives. The Company's specialized
filtration and leukoreduction technologies may also be used to remove both
cellular contamination (including intra-cellular viruses) and reaction
by-products of the chemical inactivation process.

The Company has developed or licensed several compounds and is
currently evaluating their use in the Company's SteriPath System and in other
products. In vitro experimentation on these compounds

-5-






is ongoing in both Company laboratories and in those of the American Red Cross.
Animal studies are being performed on behalf of the Company at the Navy Blood
Research Laboratory of Boston University.

The Company is investigating three basic technologies for blood
pathogen inactivation:

Aldehydes. The Company has licensed patented technology on the use of
low concentrations of formaldehyde for pathogen inactivation of cellular blood
products. Formaldehyde is an effective sterilization agent which is well
understood and widely used. The Company has demonstrated that at low
concentrations, formaldehyde is an effective pathogen inactivator in blood and
blood products. Formaldehyde works by forming methylene bridges between adjacent
nucleic acid pairs, thereby rendering them inactive. Formaldehyde at low
concentrations is ubiquitous in food and human tissues and is readily
metabolized to carbon dioxide by enzymes present in a variety of human tissues,
including red blood cells.

The Company's patented formaldehyde-based pathogen inactivation
procedure employs a sufficiently high concentration of formaldehyde to assure
complete pathogen inactivation of enveloped and non-enveloped viruses, bacteria
and parasites. Chemical inactivation is followed by removal of residual
formaldehyde or reaction by-products with a specially modified leukoreduction
filter currently under development.

Hydroxymethyl Amino Acids. The Company is also developing proprietary
pathogen inactivation chemistries based on the reaction of hydroxymethyl amino
acids with nucleic acids. Hydroxymethyl amino acids are synthesized by reacting
amino acids with formaldehyde. The Company has filed patent applications on the
use of these compounds for pathogen inactivation in blood and blood products.
The Company's lead compound of this class has been shown in vitro tests to
effectively inactivate pathogens in blood. This compound is currently widely
used as an anti-microbial agent in topical pharmaceuticals and cosmetics.

The Company has commissioned animal studies to demonstrate the safety
of its hydroxymethyl amino acid-based procedures and experiments to demonstrate
its efficacy in pathogen inactivation. The Company received FDA approval of its
request to classify its SteriPath System as a device in April 1996 and filed an
IDE application with the FDA for a hydroxymethyl amino acid-based SteriPath
System in December 1996.

Methylene Blue. Methylene blue is an effective inactivator of enveloped
viruses and is currently used in Europe for the viral inactivation of fresh
frozen plasma for transfusion. Methylene blue inactivates certain viruses by the
generation of reactive singlet oxygen when exposed to light. Singlet oxygens can
break apart molecules in their vicinity. However, methylene blue treatment is
not effective against non-enveloped viruses (such as hepatitis A) or
intra-cellular viruses present in leukocytes. Also, methylene blue treated
plasma presents a poor appearance, and questions have been raised about its
long-term toxicity. The Company's LeukoVir-MB Filter, currently awaiting
marketing approval in Europe, is designed to remove methylene blue, leukocytes
and other contaminants from treated plasma thereby addressing concerns about
toxicity and appearance.

The Company is also developing technologies to enhance the
effectiveness of methylene blue as an anti-pathogen agent. In addition, the
Company has developed and has filed patent applications on a "viral transform"
technology that seeks to transform non-enveloped viruses found in plasma into an
"enveloped-virus form," thus making these non-enveloped viruses susceptible to
the inactivating action

-6-






of methylene blue. This new "viral transform" technology may allow for
inactivation of both enveloped and non-enveloped viruses by methylene blue
treatment.

Removal of Pathogen Inactivation Agents. The Company is utilizing its
specialized filtration and sorbent technologies to remove excess anti-pathogen
agents and reaction by-products from blood components processed with its
SteriPath System. These technologies are intended to be effective when used in
connection with any of the Company's aldehyde, hydroxymethyl amino acid,
methylene blue and alphahydroxymethyl inactivation chemistries.

Affinity Separations

Leukocytes. The Company has proprietary affinity separations technology
that utilizes ligands, which are molecules that bind to complementary
biomolecules, in connection with the Company's various filtration products. The
Company has identified a family of carbohydrate-based ligands that recognize and
bind to the cell surface receptors on leukocytes. The Company has filed patent
applications covering the use of these carbohydrate-based ligands for removing
leukocytes.

Free Hemoglobin. The Company has developed a proprietary affinity
separations technology for removal of free hemoglobin, the oxygen carrying
chemical component normally contained within red blood cells. The Company has
identified a family of phosphated affinity ligands that bind to free hemoglobin.
The Company believes that these ligands, when chemically bonded to filtration
media, can be used to remove free hemoglobin contamination in blood prior to
reinfusion into patients. The Company has filed patent applications covering the
use of these ligands in removing free hemoglobin. The Company has been issued a
patent on the HemoNet Filter, which incorporates certain phosphated affinity
ligands, including those utilized to remove free hemoglobin.

Organic Chemical Synthesis

The Company is currently utilizing its expertise in organic chemical
synthesis to synthesize pathogen inactivation chemicals as well as to develop
selective ligands for the removal of such chemicals and various biomolecules.

The Company has synthesized hydroxymethyl amino acids, which can be
prepared by reacting formaldehyde with amino acids. The Company intends to
incorporate hydroxymethyl amino acids into its SteriPath System and patent
applications related thereto have been filed in the United States.

Membrane Technology

The Company believes that, as a result of the research and development
work performed at Sepracor over an eight-year period and transferred to the
Company on January 1, 1994, the Company has expertise in the field of
separations technology using both composite matrices and flat- and hollow-fiber
membranes. Successful separation of a substance from its source depends on
matching the properties of that substance, such as size, molecular weight and
surface characteristics, to appropriate separations media. The ability to select
and modify the composition and physical structure of the media is a key to
successful separations technology. The Company can utilize a variety of media
compositions, custom made structures and surface modifications, including the
attachment of selective ligands, to separate a diverse variety of substances.
The Company's separations technologies can be used to separate substances
including particulates, such as cells and debris, macromolecules, such as
enzymes, and low

-7-






molecular weight substances, such as salts, nutrients and anti-viral chemicals.
See "-- Relationship with Sepracor."

Device Design and Fabrication

The Company believes that the benefits of high performance separations
media can only be realized in a well-designed device where access to and
placement of the media, hydrodynamics and selection of biocompatible materials
have been optimized. The Company has expertise in module design, including
theoretical calculations of mass transfer, hydrodynamic modeling, prototyping,
testing and manufacturing engineering.

Drawing from this expertise, the Company is integrating its proprietary
technologies in device design and media development with blood flow control
systems, tubing, collection containers and other assembly components, in devices
which are designed to achieve efficiency in increasing the safety of donated
blood and improving certain blood transfusion and collection procedures. The
Company considers its device design and fabrication capabilities to be
proprietary and intends to file patent applications where appropriate.

The Company has undertaken preliminary studies on the use of the
filtration media used in the LeukoNet System in other applications such as the
removal of tumor cells from peripheral stem cell preparations.

Plasma Pharmaceuticals

In May 1996, the Company acquired, through its United States and Danish
subsidiaries, the plasma product unit of Novo Nordisk A/S, a Danish company
("Novo Nordisk"). See "--Agreements." The Company's plasma product unit
processes blood plasma into plasma pharmaceutical products. In February 1997,
the Company determined to discontinue the development and operation of its
Danish plasma business due, in large part, to Pharmacia & Upjohn's ("P&U")
wrongful termination of the Company's planned acquisition of P&U's plasma
division in Sweden, which was a critical part of the Company's initial strategy
to enter the plasma business, as well as certain other factors. In that regard,
the Company currently is considering various strategic alternatives to effect
that determination promptly, including, but not limited to, the sale or other
disposition of its plasma business, or an orderly liquidation of its assets. The
Company is currently engaged in preliminary discussions with a third party
regarding the potential sale of the Company's Danish plasma business. There can
be no assurance, however, that the Company will enter into a definitive
agreement relating to the sale of such business or that such a sale will be
consummated. See "-- Agreements," Item 3, "Legal Proceedings" and Item 7,
"Management's Discussion and Analysis of Financial Condition and Results of
Operations." The Company recorded a one-time charge of $15,200,000 in the fourth
quarter of 1996 associated with the exit from the plasma business.

Agreements

Under the terms of the May 1996 agreement relating to the Company's
acquisition of the plasma product unit of Novo Nordisk (the "Denmark
Acquisition"), the purchase price to be paid for the plasma product unit was to
be comprised of three portions. The first portion of $1,800,000 was to be
payable in 1998 in cash or Common Stock of the Company or a subsidiary of the
Company, at the Company's option. The second portion of approximately
$13,000,000 was to be payable from time to time upon the

-8-






sale of acquired inventory (valued at approximately $13,000,000) but in any
event no later than 1998, provided that up to approximately $3,000,000 of such
portion could be forgiven in certain circumstances. The third portion of the
purchase price of approximately $8,000,000 was to be payable in 1998 in cash or
Common Stock of the Company or a subsidiary of the Company, at the Company's
option, provided that all of this portion may be forgiven in certain
circumstances. In January 1997, the Company and Novo Nordisk entered into a
Restructuring Agreement relating to the Novo Acquisition (the "Restructuring
Agreement"). Pursuant to the Restructuring Agreement, approximately $23,000,000
million of indebtedness owed to Novo Nordisk was restructured by way of issuance
by the Company to Novo Nordisk of a 12% convertible subordinated promissory note
in the principal amount of approximately $11,722,000, which is due and payable
on December 31, 2001, with interest payable quarterly (provided that up to
approximately $3,000,000 may be forgiven in certain circumstances).
Approximately $8,500,000 of the reduction of such indebtedness was forgiven. The
remainder of the reduction represents a net amount due from Novo Nordisk to the
Company related to various service arrangements between the two companies. All
amounts outstanding under such note are convertible by either party, commencing
January 1998, into shares of Common Stock of the Company at a conversion price
equal to $10.50 per share. Pursuant to a separate Registration Rights Agreement,
the Company granted Novo Nordisk certain registration rights with respect to any
shares of Common Stock acquired by Novo Nordisk upon conversion.

In June 1996, the Company entered into a ten-year Master Strategic
Alliance Agreement with the American Red Cross BioMedical Services, a
not-for-profit, charitable corporation ("ARCBS"), which provides for, among
other things, the development and expansion of a strategic alliance between the
Company and ARCBS in the areas of (i) pathogen inactivation for blood components
and (ii) the co-development of enhanced versions of the Company's leukoreduction
filter. The agreement also contemplates the establishment of pricing and royalty
arrangements between the parties upon the development and commercialization of
certain products. No assurance can be given, however, that such products will
ultimately be developed or that any definitive development arrangements with
respect to such products will result from the strategic alliance with ARCBS.

In March 1996, the Company entered into a three-year agreement with
ARCBS for the sale of the LeukoNet System. The agreement provides for target
purchases by ARCBS over the term of this agreement. The Agreement does not
include minimum purchase obligations by ARCBS. The ARCBS has the right to
terminate the agreement under certain circumstances. The Company agrees to
indemnify the ARCBS against all losses, damages and liabilities incurred for
infringement of patent rights owned or held by Pall Corporation in connection
with the use of Company products delivered under the terms and conditions of the
contract. See Item 3, "Legal Proceedings."

In February 1996, the Company signed a cooperation agreement with the
German Red Cross of Lower Saxony. Under the terms of the agreement, the Company
will be the worldwide nonexclusive licensing agent for the methylene blue
process (excluding the United States, Canada, Puerto Rico and Switzerland). Both
parties have agreed to collaborate on advancing the methylene blue process in
order to broaden its acceptance worldwide.

Competition

The Company expects to encounter intense competition in the sale of its
products. The Company's products will compete with other products currently on
the market as well as with future products developed by biotechnology and
pharmaceutical companies, hospital supply companies, national

-9-






and regional blood centers, certain governmental organizations and agencies and
academic institutions. Many of the Company's competitors in the field of
leukocyte reduction have substantially greater resources, manufacturing and
marketing capabilities, research and production staffs and production facilities
than the Company. Moreover, some of the Company's competitors have greater
experience in preclinical testing, human clinical trials and other regulatory
approval procedures. The Company's ability to compete successfully will depend,
in part, on its ability to develop and maintain products which are technically
superior to and/or of lower cost than those currently on the market; develop
proprietary products; attract and retain scientific personnel; obtain patent or
other proprietary protection for its products and technologies; obtain required
regulatory approvals; and manufacture, assemble and successfully market any
products it develops. In addition, many of the Company's competitors have
long-standing relationships with the national and regional blood centers to
which the Company will market its products.

Leukocyte Removal. In the area of leukocyte removal, the Company will
compete primarily with Pall Corporation, which manufactures and sells a
substantial majority of leukocyte removal filters currently on the market and
has long-standing and, in certain cases, exclusive, relationships, including
long-term supply contracts, with the blood centers that are the Company's target
customers. In addition, the Company will compete with Baxter Healthcare
Corporation ("Baxter") and Asahi America, Inc. ("Asahi") which have formed an
alliance pursuant to which Baxter exclusively markets Asahi's leukocyte removal
products in North America. The Company expects that the principal competitive
factors in the area of leukocyte removal will be removal efficiency, cost and
ease of use.

Pathogen Inactivation. Although there are viral inactivation systems
available for plasma alone, the Company believes that there are currently no
effective commercially available pathogen inactivation methods for cellular
blood components. However, the Company believes that significant research and
development efforts are being expended and that competitive products will be
developed. An alternative approach to leukocyte removal and pathogen
inactivation is synthetic blood substitutes which might be used in certain
limited transfusion situations. While the Company believes that progress in the
area of blood substitutes has been limited, there can be no assurance that blood
substitutes will not be successfully developed and commercialized.


The Company is pursuing areas of product development in a relatively
new field in which there is a potential for extensive technological innovation
in relatively short periods of time. The Company's competitors may succeed in
developing technologies or products that are more effective than those of the
Company. Rapid technological change or developments by others may result in the
Company's technology or proposed products becoming obsolete or noncompetitive.

Licenses, Patents and Proprietary Information

The Company has entered into a Technology Transfer and License
Agreement with Sepracor under which Sepracor has transferred to the Company all
rights to the technology developed by Sepracor for the development, manufacture,
use and sale of medical devices for the separation and purification of blood and
blood components, including technology relating to (1) optimization of flat
membranes, hollow fiber membranes and fibrous supports; (2) specific affinity
and immunoaffinity ligands; (3) linking chemistries; (4) surface modification
including hydrophilic polymers and coatings; (5) device designs and engineering;
(6) fabrication and manufacturing including encapsulation and assembly
techniques; and (7) organic chemical synthesis. See "-- Relationship with
Sepracor."

The Company believes that protection of the proprietary nature of its
products and technology is critical to its business. Accordingly, it has adopted
and will maintain a vigorous program to secure and maintain such protection. The
Company's practice is to file patent applications with respect to technology,
inventions and improvements that are important to its business. The Company also
relies on trade secrets, unpatented know-how, continuing technological invention
and the pursuit of licensing opportunities to develop and maintain its
competitive position. There can be no assurance that others will not
independently develop substantially equivalent proprietary technology or that
the Company can meaningfully protect its proprietary position.

To date, the Company owns or has filed 20 patent applications in the
United States relating to blood filtration and pathogen inactivation
technologies. Corresponding foreign patent applications have been filed with
respect to certain of these United States patent applications. Where
appropriate, the Company intends to file, or cause to be filed on its behalf,
additional patent applications relating to future discoveries and improvements,
including, among other things, the use of certain ligands for affinity
separations. To date, four patents have been issued to the Company (which expire
at various dates from 2011 through 2017) and two patents have been allowed.

The Company's success depends in part on its ability to obtain patents,
to protect trade secrets, to operate without infringing upon the proprietary
rights of others and to prevent others from infringing on the proprietary rights
of the Company. Proprietary rights relating to the Company's planned products
will be protected from unauthorized use by third parties only to the extent that
they are covered by valid and enforceable patents or are maintained in
confidence as trade secrets. There can be no assurance that any patents owned by
or licensed to the Company will afford protection against competitors or that
any pending patent applications now or hereafter filed by or licensed to the
Company will result in patents being issued. Competitors, including those with
substantially greater resources than the Company, may seek to challenge the
validity of the patents owned by or licensed to the Company or may use their
resources to design comparable products that do not infringe these patents. See
Item 3, "Legal Proceedings."

There are many issued third-party patents in the field of blood
filtration, including patents held by competitors of the Company. The Company
may need to acquire licenses to, or contest the validity of, some of such
patents. It is likely that significant funds would be required to defend any
claim that the Company infringes a third-party patent, and any such claim could
adversely affect sales of the challenged product until the claim is resolved.
There can be no assurance that any license required under any such patent would
be made available on acceptable terms or that the Company would prevail in any
litigation involving such patent.

Much of the know-how of importance to the Company's technology and many
of its processes are dependent upon the unpatentable knowledge, experience and
skills of its key scientific and technical personnel. To protect its rights and
to maintain the confidentiality of trade secrets and proprietary information,
the Company requires all of its employees, consultants and commercial partners
and members of its Scientific/Medical Advisory Board to agree to keep the
Company's proprietary information confidential. These agreements generally
prohibit the disclosure of confidential information to anyone outside the
Company and require disclosure and assignment to the Company of ideas,
developments, discoveries and inventions. There can be no assurances, however,
that these agreements will provide meaningful protection for the Company's
proprietary information in the event of unauthorized use or disclosure of such
information.

Government Regulation

Government regulations in the United States and other countries are a
significant factor in the research, development and commercialization of the
Company's products. The products manufactured and marketed by the Company are
subject to regulation by the FDA and similar authorities in foreign countries.
The Company believes that all of its products will be classified as "devices"
under federal law and FDA regulations. The process of obtaining approvals from
the FDA and other regulatory authorities can be costly, time consuming and
subject to unanticipated delays. There can be no assurance that the FDA will
approve any of the Company's products for marketing or, if they are approved,
that they will be approved on a timely basis.

Among the conditions for FDA approval of a drug, biologic or device is
the requirement that the manufacturer's quality control and manufacturing
procedures conform to cGMP, which must be followed at all times. Although the
Company's facilities and manufacturing procedures are designed to conform to
cGMP, there can be no assurance that the FDA will determine that they conform.
These practices control every phase of production from the incoming receipt of
raw materials, components and subassemblies to the labeling of the finished
product, tracing of consignees after distribution and follow-up and reporting of
complaint information.

Medical Devices

The Company believes that its blood filtration products will be
classified as medical devices. All medical devices introduced to the market
since 1976 are required by the FDA, as a condition of marketing, to secure
either a 510(k) premarket notification clearance or an approved PMA. A 510(k)
premarket notification clearance indicates FDA agreement with an applicant's
determination that the product for which clearance has been sought is
substantially equivalent to another medical device that was on the market prior
to 1976. An approved PMA application indicates that the FDA has determined that
the device has been proven, through the submission of clinical data and
manufacturing information, to be safe and effective for its labeled indications.
The process of obtaining a 510(k) clearance typically takes at least six months,
and may take several years, and involves the submission of clinical data and
supporting information, while the PMA process typically lasts at least several
years and requires the submission of significant quantities of clinical data and
supporting information. The Company intends to seek 510(k) premarket
notification clearance for its blood filtration products. There can be no
assurance that the FDA will conclude that any of the Company's products, other
than the LeukoNet System, meet the requirements for 510(k) premarket
notification clearance.

In the event the FDA does not classify the Company's planned blood
filtration products as medical devices, these products would probably be
regulated as drugs or biologics. If regulated as drugs or biologics, the
products would require premarket approval, as described below. The Company
believes that the FDA will classify the Company's blood filtration and surgical
blood recovery products as medical devices.

In April 1996, the Company received notification from the FDA that its
SteriPath System will be classified as a device for regulatory purposes. The
activities required before the Company's system, classified as a device, may be
marketed in the United States include (1) preclinical laboratory tests in
animals and formulation and stability studies, (2) the submission to the FDA and
approval of an IDE for human clinical testing, (3) adequate and well controlled
human clinical trials to prove the safety and effectiveness of the system, (4)
the submission of a PMA and (5) the approval by the FDA of the PMA.

-12-







Manufacturing and Facilities

The Company's facilities consist of approximately 45,000 square feet of
leased office, laboratory and manufacturing space in a modern facility in
Marlborough, Massachusetts, short-term leased office space in Manhattan, and
approximately 48,000 square feet of leased office, laboratory and manufacturing
space in Copenhagen, Denmark. The Company believes that these facilities are
adequate and suitable for its needs through 1997. See Item 2, "Properties."

The leased facilities in Massachusetts include 25,000 square-feet of
product development and manufacturing space. This space is expected to be
adequate to address clinical and early commercial-scale production requirements
of the Company through 1997. The facility is designed to conform to cGMP and
other applicable government standards. The Company anticipates that its facility
will be subject to ongoing inspections by the FDA and foreign regulatory
authorities in connection with their review of the Company's products.

For manufacturing outside the United States, the Company will also be
subject to foreign regulatory requirements governing human clinical trials,
manufacturing and marketing approval for drugs or biologics and medical devices.
The regulatory requirements may vary widely from country to country.

Employees

As of March 1, 1997, the Company employed a total of 213 persons of
whom 25 were in research and development, 143 were in manufacturing and
manufacturing support and 45 were in sales and administration. Four of the
Company's employees hold Ph.D. degrees. A total of 148 employees are located in
Denmark. All but seven of the Company's 65 United States employees are located
at its facilities in Marlborough, Massachusetts.

Relationship with Sepracor

The Company was organized in December 1993 as a wholly-owned subsidiary
of Sepracor. Effective January 1, 1994, Sepracor transferred its blood
filtration and membrane filter design business to the Company in exchange for
3,000,000 shares of Common Stock. Sepracor currently owns 37% of the Company's
Common Stock.

Sepracor is engaged in the business of using chiral chemistry to
develop single-isomer forms of existing, widely sold pharmaceuticals and to
supply major pharmaceutical companies with bulk quantities of chiral
intermediates.

Technology Transfer and License Agreement. The Company and Sepracor
entered into a Technology Transfer and License Agreement, dated as of January 1,
1994 (the "Technology Transfer Agreement"), pursuant to which Sepracor
transferred to the Company all technology owned or controlled by Sepracor,
including trade secrets, patents and patent applications, that relates to and is
used in researching, developing or manufacturing products in the "Company
Field." The Company Field means the development, manufacture, use or sale of
medical devices for the purification of blood, blood products or blood
components and membrane filter design. Further, Sepracor has granted an
exclusive license to the Company for any improvements to the transferred
technology useful in the Company Field which are developed, or otherwise
acquired, by Sepracor during the period beginning on the date of the Technology
Transfer Agreement and terminating on the earlier of January 1, 1998 or the
acquisition of Sepracor or

-13-






the Company (the "Effective Period"). The Company has granted to Sepracor an
exclusive license to the transferred technology for the development,
manufacture, use or sale of any products within the field of chiral synthesis,
chiral separations and the development, manufacture, use or sale of chiral drugs
and chiral drug intermediates (the "Sepracor Field"), as well as a non-exclusive
license to the transferred technology for the development, manufacture, use or
sale of any products outside the Company Field. All licenses are royalty-free.
Sepracor has also granted the Company a right of first refusal to any product
which Sepracor proposes to sell, or license a third party to sell, during the
Effective Period, for use within the Company Field.

Cross-License Agreement. The Company has entered into a Cross-License
Agreement, dated as of January 1, 1994 (the "Cross-License Agreement"), with
BioSepra Inc., a subsidiary of Sepracor ("BioSepra"). Effective January 1, 1994,
Sepracor transferred to BioSepra its technology relating to the separation of
biological molecules, but not for use in the Company Field or the Sepracor Field
(the "BioSepra Field"). Under the terms of the Cross-License Agreement, the
Company and BioSepra have each granted to the other a perpetual, royalty-free
and non-exclusive right and license to technology and improvements owned or
controlled by the licensing party for use in the BioSepra Field and the Company
Field, respectively. The Cross-License Agreement will terminate on the earlier
of January 1, 1998 or the acquisition of BioSepra or the Company.

Sale of Membrane Products. From inception through December 31, 1995,
the Company's sales of membrane models to Sepracor amounted to $668,000. Such
sales did not continue in any material respect beyond December 31, 1995. See
Item 14, "Exhibits, Financial Statement Schedules, and Reports on Form 8-K--
Financial Statements -- Notes to Consolidated Financial Statements --
Discontinued Business" (Note B).

Registration Rights. Sepracor has certain registration rights with
respect to its shares in the Company as provided in the Technology Transfer
Agreement.

All future arrangements and transactions between the Company and
Sepracor will continue to be on terms which the Company determines are fair and
reasonable to the Company.

Item 2. PROPERTIES

The Company's facilities consist of approximately 45,000 square feet of
leased office, laboratory and manufacturing space in a modern facility in
Marlborough, Massachusetts (which lease expires in February 2004, and provides
for two five-year renewal options thereafter), short-term leased office space in
Manhattan, and approximately 48,000 square feet of subleased office, laboratory
and manufacturing space in Copenhagen, Denmark (which subleases expires in 2009,
subject to early termination by the Company in March 1998, under certain
circumstances). The Company believes that these facilities are adequate and
suitable for its needs through 1997. See Item 1. "Business -- Manufacturing and
Facilities."

Item 3. LEGAL PROCEEDINGS

The Company is a defendant in two lawsuits brought by Pall Corporation
("Pall"). In complaints filed in February 1996 and November 1996, Pall alleged
that the Company's manufacture, use and/or sale of the LeukoNet product
infringes upon three patents held by Pall.

On October 14, 1996, in connection with the first action concerning
U.S. Patent No. 5,451,321, the Company filed a motion for summary judgment of
noninfringement. Pall filed a cross motion for summary judgment of infringement
at the same time. The parties are awaiting the Court's decision.

With respect to the second action concerning U.S. Patent Nos. 4,340,479
(the "'479 patent") and 4,952,572 (the "'572 patent"), the Company has answered
the complaint stating that it does not infringe any claim of the asserted
patents. Further, the Company has counterclaimed for declaratory judgment of
invalidity, noninfringement and unenforceability of the '572 patent, and a
declaratory judgment of noninfringement of the '479 patent, as a result of a
license.

The Company believes, based on advice of its patent counsel, that a
properly informed court should conclude that the manufacture, use and/or sale by
the Company or its customers of the present LeukoNet product does not infringe
any valid enforceable claim of the three asserted Pall patents. However, there
can be no assurance that the Company will prevail in the pending litigations,
and an adverse outcome in a patent infringement action would have a material
adverse effect on the Company's future business and operations.

On November 1, 1996, the Company filed a complaint in the Supreme
Court, State of New York, County of New York, against Pharmacia & Upjohn, Inc.
The action was removed by P&U to the United States District Court for the
Southern District of New York. P&U has also made a motion to refer the entire
matter to arbitration in Sweden. The Company is opposing P&U's motion, and has
cross moved to remand the action to the Supreme Court, State of New York, County
of New York. This motion is still pending bfore the court. In its complaint, the
Company seeks $168 million in compensatory damages and $100 million in punitive
damages arising out of, among other things, P&U's breach of its commitment to
sell the business to the Company following its year long efforts to acquire
P&U's plasma business. The Company intended to integrate P&U's plasma business
with the complimentary plasma business it previously acquired from Novo Nordisk
in May 1996. There can be no assurance that the Company will prevail in this
litigation or, if the Company does so prevail, as to the amount of damages, if
any, that will be awarded or that the Company may collect.

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

No matters were submitted to a vote of security holders of the Company,
through solicitation of proxies or otherwise, during the last quarter of the
year ended December 31, 1996.

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

Overview

The Company was established in December 1993 as a wholly-owned
subsidiary of Sepracor. Prior to that date, its business was conducted as part
of Sepracor's bioprocessing division. Since 1986, Sepracor has made significant
investment in the research and development of technology relating to flat- and
hollow-fiber membranes and fibrous supports; specific affinity ligands; linking
chemistries; membrane surface modification; device design and engineering;
fabrication and manufacturing; and organic chemical synthesis. Effective as of
January 1, 1994, in exchange for 3,000,000 shares of Common Stock, Sepracor
transferred to the Company its technology relating to the manufacture, use and
sale of medical devices for the separation and purification of blood, blood
products and blood components and its membrane filter design technologies.

In the second quarter of 1994, The Company completed the initial public
offering of its Common Stock resulting in net proceeds to the Company of
approximately $15 million. In September 1995, the Company completed a follow-on
public offering of its Common Stock. The net proceeds from that public offering
were approximately $43 million. Sepracor currently owns approximately 37% of the
outstanding Common Stock of the Company.

Substantially all of the Company's revenues through 1995 were
attributable to sales of non-blood related membrane filter products to Sepracor.
Revenues from these products were $13,000, $517,000, and $339,000 in 1996, 1995
and 1994, respectively, and are not expected to continue in any material respect
beyond 1996. Fiscal 1996 was the first full year of commercial sale of its
currently marketed blood-related product. A majority of the Company's planned
blood-related products are in the research and development stage, and certain of
these products may require preclinical and clinical testing prior to submission
of any regulatory application for commercial use. The Company's success will
depend on development and commercial acceptance of these blood-related products.

Through 1995, the Company's operations were located in facilities
subleased from Sepracor for which the Company was allocated and charged a
portion of Sepracor's rent and operating costs based upon the amount of spaces
its occupies. During this period, Sepracor also provided support services,
including laboratory support, data processing, accounting and finance, legal and
other administrative functions. Sepracor allocated a portion of the costs of
these activities to the Company based upon its pro rata usage of such services.
The Company signed a long-term lease for its manufacturing, laboratory, research
and office space which took effect in February 1996. Commencing in 1996, the
Company provided the necessary data processing, accounting and finance and other
support services through its own employees or outside contractors engaged
directly by the Company.

In May 1996, the Company acquired the plasma product unit of Novo
Nordisk, and in January 1997, entered into a Restructuring Agreement with Novo
Nordisk with respect to the indebtedness incurred by the Company in connection
with the Denmark Acquisition. In addition, in February 1997, the Company
determined to discontinue the development and operation of its Danish plasma
business due in large part to P&U's wrongful termination of the Company's
planned acquisition of P&U's plasma business in Sweden. The Company recorded a
one-time charge as a result of its exit from the plasma business of $15,200,000
in 1996. See "-- Discontinued Business" and "-- Liquidity and Capital
Resources."

-20-







Results of Continuing Operations

Revenues were $779,000 in 1996, $834,000 in 1995, and $389,000 in 1994.
Revenues from products sales to Sepracor, a related party, as a percentage of
total revenues were 2% in 1996, 57% in 1995, and 50% in 1994 and represent the
sale of membrane filter products. Product sales to Sepracor are recorded at
prices based on a pricing agreement between the Company and Sepracor. Under this
pricing agreement, product sales to Sepracor for Sepracor's use are at cost
while product sales to Sepracor for subsequent sale or lease to third parties
are at cost plus a 25% margin. Revenues in 1996 include $54,000 related to the
Company's Phase II SBIR program with the United States Department of the Army.
In 1995 and 1994, collaborative research and development revenues were $300,000
and $50,000, respectively. In 1996, one customer represented 83% of total
revenues. In 1995, one customer represented 36% of total revenues while in 1994,
two customers each represented 18% of total revenues.

The cost of products sold was $3,785,000 in 1996, $1,073,000 in 1995,
and $353,000 in 1994. Cost of products sold exceeded product sales in all
periods due to the start-up costs of new product introduction and the high costs
associated with low volume production, particularly in 1996, the first full year
of production of its LeukoNet System, a medical device designed for the removal
of contaminating leukocytes from donated blood.

The cost of collaborative research and development was $41,000 in 1996,
$283,000 in 1995, and $32,000 in 1994. The decrease in 1996 over 1995 reflects
the completion in the first quarter of 1996 of the Company's obligations under
Phase II of the SBIR program. The increase in 1995 over 1994 was related to the
Phase II SBIR program which required a higher level of effort than collaborative
programs in prior years.

Research and development expenses were $6,128,000 in 1996, $4,061,000
in 1995, and $3,249,000 in 1994. The increase in 1996 over the amounts expended
in 1995 and 1994 is primarily attributable to a higher level of spending
associated with development of the Company's SteriPath Blood Pathogen
Inactivation System and preparation for commercialization of the Company's
LeukoNet System.

Selling, general and administrative expenses were $8,069,000 in 1996,
$3,881,000 in 1995, and $1,584,000 in 1994. The increase in 1996 and 1995 over
1994 is primarily attributable to expenses associated with preparation for
commercialization of the LeukoNet System, increased costs related to the hiring
of management with specific industry experience and administrative costs
associated with being a public company. The 1996 expense also includes expenses
for personnel, consultants and travel in connection with the Company's efforts
to expand into other blood related businesses and a one-time charge of
approximately $1,500,000 in connection with the Company's efforts to acquire
P&U's plasma business. See "--Discontinued Business."

Interest income, net in 1996, 1995 and 1994, primarily represents
interest earned on available cash and marketable securities balances during
those periods.

Other expense in 1996 primarily represents the loss recognized on the
disposition of property and equipment.

Discontinued Business

In May 1996, the Company consummated the Denmark Acquisition. The
purchase price for the transaction was comprised of a combination of Promissory
Notes, Convertible Subordinated Notes (which would convert to common stock of
the Company or a subsidiary of the Company) and additional consideration payable
in 1998 in cash or Common Stock, at the option of the Company, which would not
be paid in certain events. See Item 1, "Business -- Plasma Pharmaceuticals and
- -- Agreements."

The loss from operations of discontinued business of $9,550,000
reflects the loss from the date of the acquisition through December 31, 1996.
During this eight month period, this business recorded revenues from the sale of
plasma products of $8,200,000 and cost of products sold of $13,400,000. The cost
of products sold includes a reserve for the write down of inventories to the
lower of cost or market of approximately $2,500,000 and loss on the sale of raw
materials inventories of approximately $800,000. Operating costs of this
business during this period were approximately $4,000,000.

In January 1997, the Company and Novo Nordisk entered into a
Restructuring Agreement of the debt related to the Denmark Acquisition. Pursuant
to the Restructuring Agreement, approximately $23,000,000 of indebtedness owed
to Novo Nordisk was restructured by way of issuance by the Company to Novo
Nordisk of a 12% convertible subordinated promissory note in the principal
amount of $11,700,000, which is due and payable on December 31, 2001, with
interest payable quarterly (provided that up to $3,000,000 may be forgiven in
certain circumstances). Approximately $8,500,000 of the reduction of such
indebtedness was forgiven. The remainder of the reduction represents a net
amount due from Novo Nordisk to the Company related to various service
arrangements between the two companies.

On February 20, 1997, the Company's Board of Directors voted to
discontinue the development and operation of its Danish plasma business due in
large part to P&U's wrongful termination of the Company's planned acquisition of
P&U's plasma business in Sweden, which was part of the Company's initial
strategy to enter the plasma business, as well as other factors. In that regard,
the Company is currently considering various strategic alternatives to effect
that determination promptly, including, but not limited to, the sale or other
disposition of its plasma business, or an orderly liquidation of its assets. In
connection with this determination, the Company recorded a one-time charge of
$15,200,000 in 1996 as a result of its exit from the plasma business. The loss
reflects management's assessment of the most probable outcome from this
decision, is net of the $8,500,000 forgiveness of indebtedness and assumes the
$3,000,000 forgiveness contingency.

New Accounting Standards

In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 128, "Earnings Per Share" (SFAS
128), which will be effective for the Company in fiscal 1997. SFAS 128 is
designed to improve the EPS information provided in financial statements by
simplifying the existing computational guidelines (i.e., APB Opinion No. 15,
Earnings Per Share), revising the disclosure requirements, and increasing the
- ------------------
comparability of EPS data on an international basis. SFAS 128 requires dual
presentation of basic and diluted EPS on the face of the income statement for
all entities with complex capital structures regardless of whether basic and
diluted EPS are the same; it also requires a reconciliation of the numerator and
denominator used in computing basic and diluted EPS. Management has not yet
determined the impact of adopting SFAS 128.


-22-






Litigation

The Company is a defendant in two lawsuits brought by Pall. In
complaints filed in February 1996 and November 1996, Pall alleged that the
Company's manufacture, use and/or sale of the LeukoNet product infringes upon
three patents held by Pall.

On October 14, 1996, in connection with the first action concerning
U.S. Patent No. 5,451,321, the Company filed a motion for summary judgment of
noninfringement. Pall filed a cross motion for summary judgment of infringement
at the same time. The parties are awaiting the Court's decision.

With respect to the second action concerning U.S. Patent Nos. 4,340,479
(the "'479 patent") and 4,952,572 (the "'572 patent"), the Company has answered
the complaint stating that it does not infringe any claim of the asserted
patents. Further, the Company has counterclaimed for declaratory judgment of
invalidity, noninfringement and unenforceability of the '572 patent, and a
declaratory judgment of noninfringement of the '479 patent, as a result of a
license.

The Company believes, based on advice of its patent counsel, that a
properly informed court should conclude that the manufacture, use and/or sale by
the Company or its customers of the present LeukoNet product does not infringe
any valid enforceable claim of the three asserted Pall patents. However, there
can be no assurance that the Company will prevail in the pending litigations,
and an adverse outcome in a patent infringement action would have a material
adverse effect on the Company's future business and operations.

On November 1, 1996, the Company filed a complaint in the Supreme
Court, State of New York, County of New York, against Pharmacia & Upjohn, Inc.
In its complaint, the Company seeks to receive damages arising out of the
alleged breach by P&U of an agreement to sell to the Company P&U's plasma
pharmaceutical business located in Stockholm, Sweden. The complaint seeks
compensatory, consequential and punitive damages. There can be no assurance that
the Company will prevail in this litigation or, if the Company does so prevail,
as to the amount of damages, if any, that will be awarded or that the Company
may collect. See Item 1, "Business -- Legal Proceedings."

Liquidity and Capital Resources

The Company operated as a division of Sepracor through December 31,
1993 and, accordingly, the Company's operating losses (principally research and
development expenditures) were funded by Sepracor and were included in
Sepracor's consolidated financial statements. Therefore, as of December 31,
1993, no retained deficit related to the Company's operations was recorded on
the Company's balance sheet. Sepracor provided working capital to fund the
Company's business until the closing of the initial public offering in April
1994.

The net decrease in cash and cash equivalents in 1996 was $17,501,000.
This net decrease is attributable to net cash used in operating activities of
$25,814,000 offset in part by net cash provided by investing activities of
$8,160,000.

The net cash used in operating activities is attributable to net cash
used in continuing operations of $13,845,000 and net cash used in discontinued
business of $11,969,000. Net cash used in continuing operations is primarily
attributable to the net loss of $40,598,000 and increases in net assets of
discontinued business of $500,000 and accounts receivable of $201,000. This was
offset in part by losses

-23-






of the discontinued business of $24,748,000, non-cash charges for depreciation
and amortization of $819,000, a decrease in inventories of $380,000 and an
increase in accounts payable and accrued expenses of $1,368,000.

Net cash provided by investing activities was primarily attributable to
net maturities of available for sale marketable securities of $13,465,000,
offset in part by cash used in the acquisition of business net of cash acquired
of $4,092,000 and property and equipment additions of $1,213,000.

In January 1997, the Company entered into the Restructuring Agreement
with respect to the indebtedness incurred by the Company in connection with the
Denmark Acquisition. Pursuant to the Restructuring Agreement, approximately
$23,000,000 of indebtedness owed to Novo Nordisk was restructured by way of
issuance by the Company to Novo Nordisk of a 12% convertible subordinated
promissory note in the principal amount of approximately $11,700,000, which is
due and payable on December 31, 2001, with interest payable quarterly (provided
that up to approximately $3,000,000 may be forgiven in certain circumstances).
Approximately $8,500,000 of the reduction of such indebtedness was forgiven;
such forgiveness is reflected in the 1996 Statement of Operations as a reduction
of the loss on disposal of the discontinued plasma business. The remainder of
the reduction represents a net amount due from Novo Nordisk to the Company
related to various service arrangements between the two companies. All amounts
outstanding under such note are convertible by either party, commencing January
1998, into shares of Common Stock at a conversion price equal to $10.50 per
share.

In June 1994, the Company executed an agreement with a third party to
license certain technology. Pursuant to the terms of the agreement, the Company
is committed to paying license and consulting fees of $1,200,000 payable in four
equal annual installments, and royalties for commercial sales of any product
incorporating this technology. As of December 31, 1996, license and consulting
fees of $900,000 have been paid.

The termination of the Company's revolving credit agreement with a
commercial bank, which was a collaboration arrangement with Sepracor and its
subsidiaries, took effect as of July 1, 1996. The Company does not currently
plan to renew the arrangement. In 1994, in collaboration with Sepracor and
certain of its other subsidiaries, the Company executed an equipment leasing
arrangement that provides for a total of $2 million to Sepracor and certain of
its other subsidiaries for purposes of financing capital equipment. Under
certain circumstances, Sepracor is the guarantor of any amounts outstanding
under this financing arrangement. In October 1996, the Company executed a
replacement leasing arrangement for the benefit of HemaSure only with the same
leasing company providing $1.1 million of equipment lease financing. This
arrangement terminates in March 1997. All amounts outstanding under the 1994
leasing facility are being repaid under the original terms of that leasing
arrangement. The Company has an additional leasing arrangement with another
equipment leasing company that provides for a total of $100,000 of equipment
financing. There was $759,000 outstanding under all leasing arrangements as of
December 31, 1996.

Future Operating Results

Certain of the information contained in this Annual Report in Form 10-K
including information with respect to the commercialization of the Company's
LeukoNet System and the development and commercialization of the Company's
products under development and the Company's other plans and strategy for its
business, consists of forward-looking statements. Important factors that could
cause actual results to differ materially from the forward-looking statements
include the following:

-24-







The Company believes that the performance of its blood-related products
will be competitive with products sold by other vendors of blood filtration,
transfusion and pathogen inactivation products and expects to encounter intense
competition in the sale of such products from biotechnology and pharmaceutical
companies, hospital supply companies, national and regional blood centers,
certain governmental organizations and agencies and academic institutions. In
the Leukoreduction field, several of the Company's competitors have
substantially greater resources, manufacturing and marketing capabilities,
research and production staffs and production facilities than the Company.
Moreover, some of the Company's competitors have greater experience in
preclinical testing, human clinical trials and other regulatory approval
procedures. Pall Corporation, a principal competitor of the Company, has filed
two complaints against the Company alleging that the manufacture, use and sale
of the Company's LeukoNet System infringes a certain patents held by Pall. See
Item 3, "Business -- Legal Proceedings."

The customers for the Company's potential products are a limited number
of national and regional blood centers, which collect, store and distribute
blood and blood products. In the United States, the American Red Cross collects
and distributes approximately 45% of the nation's supply of blood products.
Other major blood centers include the New York Blood Center, Blood Centers of
America and United Blood Services, each of which distributes 6% to 12% of the
nation's supply of blood and blood products. In Europe, various national blood
transfusion services or Red Cross organizations collect, store and distribute
virtually all of their respective nation's blood and blood products supply. The
Company's principal competitors have long-standing and, in some cases, exclusive
relationships (including long-term supply contracts) with these blood centers
and there can be no assurance that the Company will be successful in marketing
its products to these centers.

The Company currently buys all of its blood filter media from one
supplier under a supply contract. Although the supply agreement provides that
should the supplier be unable to produce the Company's required quantities, the
supplier will assist the Company in finding another source of supply, a
disruption in production from this supplier could cause a delay in manufacturing
and a possible loss in sales which would adversely affect operating results.

All of the Company's planned blood filtration, transfusion and pathogen
inactivation products, other than the LeukoNet System, are in the research and
development stage. The Company will be required to conduct significant research,
development, testing and regulatory compliance activities on these products
that, together with anticipated general and administrative expenses, are
expected to result in substantial losses through 1997. The Company's ability to
achieve a profitable level of operations will depend on successfully completing
development, obtaining regulatory approvals and achieving market acceptance of
its blood-related products.

Some or all of the Company's blood filtration, transfusion and pathogen
inactivation products, other than the LeukoNet System, may require preclinical
and clinical testing prior to submission of any regulatory application for
commercial use. The Company does not expect regulatory approval for commercial
sale in the United States of any of its other planned products before the end of
1997.

Based on the Company's current operating plan, the Company believes
that its available cash, cash equivalents and marketable securities balances
will be sufficient to fund the Company's operations into 1998. The Company's
cash requirements may vary materially from those now planned because of factors
such as successful development of products, results of product testing, approval
process at the FDA and similar foreign agencies, commercial acceptance of its
products, patent developments and the introduction of competitive products.

-25-







Because of the foregoing factors, past financial results should not be
relied upon as an indication of future performances. The Company believes that
period-to-period comparisons of its financial results to date are not
necessarily meaningful and its expects that its results of operations may
fluctuate from period to period in the future. See "-- Overview."

Report of Independent Accountants

To the Board of Directors and Stockholders of HemaSure Inc.

We have audited the accompanying consolidated balance sheets of
HemaSure Inc. as of December 31, 1996 and 1995, and the related consolidated
statements of operations, stockholders' equity, and cash flows for each of the
three years in the period ended December 31, 1996. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
HemaSure Inc. as of December 31, 1996 and 1995, and the consolidated results of
its operations and its cash flows for each of the three years in the period
ended December 31, 1996 in conformity with generally accepted accounting
principles.

HemaSure Inc.
Notes to Consolidated Financial Statements

A. THE COMPANY:

Nature of the Business

HemaSure Inc. (the "Company") is utilizing its proprietary filtration and
pathogen inactivation technologies to develop products to increase the safety of
donated blood and to improve certain blood transfusion procedures. The Company's
currently marketed blood filtration products are designed for use by blood
centers and hospital blood banks worldwide. From the Company's inception through
the first quarter of fiscal 1996, HemaSure has sold non-blood related filter
products primarily to Sepracor, a related party, for use in chemical processing
applications. The Company's collaborative research and development efforts have
been with the US Department of the Army for blood filtration related practices.

The Company is subject to risks common to companies in the medical
technology industry, including, but not limited to, development by the Company
or its competitors of new technological innovations, dependence on key
personnel, protection of proprietary technology, and compliance with FDA
regulations.

Basis of Presentation and Relationship with Sepracor Inc.

The Company was incorporated in December 1993 as a wholly-owned subsidiary
of Sepracor Inc. ("Sepracor") and, prior to that date, its business was
conducted as a division of Sepracor. Effective as of January 1, 1994, in
exchange for 3,000,000 shares of common stock, par value $.01 per share (the
"Common Stock"), of the Company, Sepracor transferred to HemaSure its technology
relating to the manufacture, use and sale of its membrane filter products and
medical devices for the separation and purification of blood, blood products and
blood components. The accompanying financial statements of the Company
retroactively reflect the 1994 transaction.

Certain prior year amounts have been reclassified to be consistent with
the current year presentation.

B. DISCONTINUED BUSINESS:

In May 1996, the Company acquired the plasma product unit of Novo Nordisk
A/S, a Denmark corporation ("Novo Nordisk"), through its newly formed Danish
subsidiary, HemaSure A/S (the "Denmark Acquisition"). The purchase price for the
transaction was comprised of a combination of Promissory Notes, Convertible
Subordinated Notes (which would convert to common stock of HemaSure or a
subsidiary of HemaSure) and additional consideration payable in 1998 in cash or
stock, at the option of HemaSure, which would not be paid in certain events. The
acquisition was accounted for under the purchase method of accounting. Results
of operations proformed for the Denmark Acquisition have not been presented
because the subsequent decision to discontinue the business (see below)
eliminates any comparable continuing impact on the Company's financial
statements.

The loss from operations of discontinued business of $9,550,000 reflects
the loss from the date of the acquisition through December 31, 1996. During this
eight month period, this business recorded revenues from the sale of plasma
products of $8,200,000 and cost of products sold of $13,400,000. The cost of
products sold includes a reserve for the write down of inventories to the lower
of cost or market of approximately $2,500,000 and loss on the sale of raw
materials inventories of approximately $800,000. Operating costs of this
business during this period were approximately $4,000,000.

In January 1997, the Company and Novo Nordisk entered into a Restructuring
Agreement of the debt related to the Denmark Acquisition. Pursuant to the
Restructuring Agreement, approximately $23,000,000 of indebtedness owed to

F-7






Novo Nordisk was restructured by way of issuance by the Company to Novo Nordisk
of a 12% convertible subordinated promissory note in the principal amount of
approximately $11,700,000, which is due and payable on December 31, 2001, with
interest payable quarterly (provided that up to approximately $3,000,000 may be
forgiven in certain circumstances). Approximately $8,500,000 of the reduction of
such indebtedness was forgiven; such forgiveness is reflected in the 1996
Statement of Operations as a reduction of the loss on disposal of the
discontinued plasma business. The remainder of the reduction represents a net
amount due from Novo Nordisk to the Company related to various service
arrangements between the two companies.

On February 20, 1997, the Company's Board of Directors voted to
discontinue the development and operation of its Danish plasma business due in
large part to Pharmacia & Upjohn's ("P&U") wrongful termination of the Company's
planned acquisition of P&U's plasma business in Sweden, which was part of the
Company's initial strategy to enter the plasma business, as well as other
factors. In that regard, the Company is currently considering various strategic
alternatives to effect that determination promptly, including, but not limited
to, the sale or other disposition of its plasma business, or an orderly
liquidation of its assets.

In connection with this determination, the Company recorded a one-time
charge of $15,200,000 in 1996 as a result of its exit from the plasma business.
The loss reflects management's assessment of the most probable outcome from this
decision and is net of the $8,500,000 forgiveness of indebtedness and assumes
the $3,000,000 forgiveness contingency.

C. SUMMARY OF SIGNIFICANT
ACCOUNTING POLICIES:

Cash and Cash Equivalents

The Company considers all demand deposits, money market instruments and
repurchase agreements to be cash and cash equivalents. Cash equivalents of
$5,407,000 and $22,599,000 at December 31, 1996 and 1995, respectively, consist
of repurchase agreements with a commercial bank and money market instruments
with a financial management institution. The carrying amount approximates fair
value because of the short maturity of those instruments. A repurchase agreement
for $5,407,000 outstanding at December 31, 1996 was collateralized by a United
States Federal Government Agency, had an interest rate of 4.9% and had a
maturity date of January 2, 1997.

Marketable Securities

Management determines the appropriate classification of its investments in
debt and equity securities at the time of purchase and reevaluates such
determination at each balance sheet date. At December 31, 1996 and 1995, all
marketable securities have been classified as available for sale and are carried
at fair value, with the unrealized gains and losses, if any, reported as a
separate component of stockholders' equity.

The amortized cost of debt securities classified as available for sale is
adjusted for accretion of discounts to maturity. Such accretion is included in
interest income. Realized gains and losses are included in other income or
expense. The cost of securities sold is based on the specific identification
method.


F-8






The following is a summary of the fair value of available for sale
marketable securities at December 31:

(In thousands) 1996 1995
---- ----

Commercial Paper $10,738
U.S. Government Agency Obligations $11,369 14,075
------ ------

$11,369 $24.813
======= =======

The unrealized holding loss of available for sale marketable securities
approximated $3,000 as of December 31, 1996.

As of December 31, 1995, the fair value of each investment approximated
the amortized cost, and therefore, there are no unrealized gains or losses. All
debt securities available for sale at December 31, 1996 and 1995 are due in
three months or less.

The Company's policy is to diversify the investment portfolio to reduce
risk to principal from credit and investment sector risk. At December 31, 1996
and 1995, investments were placed with a variety of high credit quality
financial institutions or other issuers.

Inventories

Inventories are stated at the lower of cost (first-in, first-out) or
market.

Property and Equipment

Property and equipment are stated at cost. Costs of major additions and
betterments are capitalized; maintenance and repairs which do not improve or
extend the life of the respective assets are charged to operations. On disposal,
the related cost and accumulated depreciation or amortization are removed from
the accounts and any resulting gain or loss is included in the results of
operations. Depreciation is computed using the straight-line method over the
estimated useful lives of the assets. All laboratory, manufacturing and office
equipment have estimated useful lives of three to ten years.

Revenue Recognition

Revenues from product sales are recognized when goods are shipped.
Revenues for research and development contracts are recorded under the
percentage of completion method wherein costs and estimated gross margin are
recorded as revenue as the work is performed.

Product Sales to Related Parties

Revenues for product sales to Sepracor are recorded at prices based on a
pricing agreement between HemaSure and Sepracor. Under this agreement, product
sales to Sepracor for Sepracor's use are at cost while product sales to Sepracor
for subsequent sale or lease to third parties are at cost plus a 25% margin.
Revenues for product sales to Sepracor subsidiaries are recorded at prices that
reflect transactions made on an arm's length basis.

Research and Development

Research and development costs are expensed in the year incurred.


F-9






Net Loss Per Share

Net loss per share is based on the weighted average number of common and
dilutive common equivalent shares outstanding during the period. Common
equivalent shares are not included in the per share calculation where the effect
of their inclusion would be antidilutive, except that, in accordance with the
Securities and Exchange Commission requirements, common and common equivalent
shares issued during the twelve-month period prior to the Company's initial
public offering have been included in the calculation as if they were
outstanding from January 1, 1994 to the Company's initial public offering in
April 1994.

Income Taxes

Net operating losses of the Company incurred while operating as a division
of Sepracor are not available for carryforward because the Company's results for
those periods were included in the consolidated tax return of Sepracor. Deferred
tax assets and liabilities reflect the estimated future tax consequences
attributable to tax benefit carryforwards and to "temporary differences" between
amounts of assets and liabilities for financial reporting purposes and such
amounts as measured by tax laws.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at December 31, 1996 and 1995
and the reported amounts of revenues and expenses during the years ended
December 31, 1996, 1995, and 1994. Actual results could differ from those
estimates.

Other

The Company adopted Statement of Financial Accounting Standards No. 121
(FAS 121), "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of", in 1995. FAS 121 requires that long-lived
assets be reviewed for impairment by comparing the fair value of the assets with
their carrying amount. Any write-downs are to be treated as permanent reductions
in the carrying amount of the assets. The adoption of FAS 121 did not have any
material financial impact on the Company.

In February 1997, the Financial Accounting Standards Board issued
Statement of Financial Accounting Standards No. 128, "Earnings Per Share" (SFAS
128), which will be effective for the Company in fiscal 1997. SFAS 128 is
designed to improve the EPS information provided in financial statements by
simplifying the existing computational guidelines (i.e., APB Opinion No. 15,
Earnings Per Share), revising the disclosure requirements, and increasing the
- ------------------
comparability of EPS data on an international basis. SFAS 128 requires dual
presentation of basic and diluted EPS on the face of the income statement for
all entities with complex capital structures regardless of whether basic and
diluted EPS are the same; it also requires a reconciliation of the numerator and
denominator used in computing basic and diluted EPS. Management has not yet
determined the impact of adopting SFAS 128.

D. ALLOCATIONS FROM AND AGREEMENTS
WITH SEPRACOR:

Since the Company's inception through December 31, 1995, all facilities
and support services of the Company, including administrative support, have been
provided by Sepracor. For these facilities and services, the Company was charged
$771,000 and $635,000 for 1995 and 1994, respectively. These charges represent
an allocation of the Company's proportionate share of Sepracor's overhead costs
using formulas developed by management based upon the Company's use of such
facilities and services. All costs incurred by the Company prior to the
Company's initial public offering in April 1994, including payroll costs, were
paid by Sepracor for the Company.

F-10







Under a Corporate Services Agreement, effective from January 1, 1994
through December 31, 1995, the Company received certain basic support services
in exchange for a fixed monthly payment, adjusted annually. The Company recorded
an expense of $244,000 and $160,000 for these services in 1995 and 1994,
respectively. These basic services included laboratory support as well as
assistance with certain administrative services, including recruiting and
benefits administration, purchasing, data processing, risk management, corporate
communications, patents and legal, accounting, finance and treasury activities.
Effective in 1996, the Company provided these services through its own employees
or outside contractors engaged directly by the Company.

Under Sublease Agreements, the Company leased certain laboratory, research
and office space from Sepracor through 1995 in exchange for fixed monthly rent
payments which increased at various dates and which approximate the Company's
proportionate share of Sepracor's cost of providing the facilities including
building maintenance, cleaning and certain utilities and other operating costs.
The Company signed a long-term lease for its manufacturing, laboratory, research
and office space in February 1996 (see Note H).

Under a Technology Transfer and License Agreement, Sepracor transferred to
the Company all technology owned or controlled by Sepracor, including trade
secrets, patents and patent applications, that relates to and is used in
researching, developing or manufacturing products in the Company Field as
defined in the agreement. Further, Sepracor has granted an exclusive license to
the Company for any improvements to the transferred technology which are
developed, or otherwise acquired, by Sepracor during the period beginning on the
date of the Technology Transfer and License Agreement and terminating on the
earlier of January 1, 1998 or the acquisition of Sepracor or HemaSure (the
"Effective Period"). The Company has granted to Sepracor an exclusive license to
the transferred technology for the development, manufacture, use or sale of any
products within the field of chiral synthesis, chiral separations and the
development, manufacture, use or sale of chiral drugs and chiral drug
intermediates, as well as a non-exclusive license to the transferred technology
for the development, manufacture, use or sale of any products outside of the
Company Field. All licenses are royalty-free. Sepracor has also granted the
Company a right of first refusal to any product which Sepracor proposes to sell,
or license a third party to sell during the Effective Period, for use within the
Company Field.

In addition, beginning in April 1998, Sepracor will be entitled to certain
rights with respect to the registration under the Securities Act of a total of
3,000,000 shares of Common Stock. These rights provide that Sepracor may require
the Company, on two occasions, to register shares having an aggregate offering
price of at least $5,000,000, subject to certain conditions and limitations.

E. ACCOUNTS RECEIVABLE:

The Company's 1996 trade receivables primarily represent amounts due for
product sales. In 1995, the Company's trade receivables primarily represented
amounts due from the United States Department of the Army related to its
collaborative research and development agreement.

The allowance for doubtful accounts was $10,000 at December 31, 1996.
There was no allowance for doubtful accounts at December 31, 1995.

The Company performs ongoing credit evaluations of its customers and
generally does not require collateral.

All of the Company's inventory at December 31, 1996 relates to its
recently marketed blood filter product. The Company has not yet established a
consistent sales level for these products in order to determine an appropriate
level of inventory. Management believes that the Company will sell its existing
inventory for these products without a loss. No estimate can be made of a range
of losses that are reasonably possible should the Company not be successful.

G. PROPERTY AND EQUIPMENT:

Property and equipment consists of the following at December 31:

in 1996, 1995 and 1994, respectively.

Accumulated amortization of assets under lease was $278,000 and $37,000 as
of December 31, 1996 and 1995, respectively.


F-12






H. COMMITMENTS AND CONTINGENCIES:

The Company leased certain laboratory, research and office space from
Sepracor through 1995. In 1995, the Company executed a lease for these facility
requirements which commences in February 1996 and extends through February 2004.
The lease provides for two five year renewal options. Under the terms of the
lease, the Company will be required to pay its allocated share of taxes and
operating costs in addition to the base annual rent.

In 1994, the Company, in collaboration with Sepracor and certain of its
other subsidiaries, executed an equipment leasing arrangement that provided for
a total of $2 million to these companies for purposes of financing capital
equipment. In October 1996, the Company executed a separate follow on equipment
leasing arrangement that provides $1.1 million of equipment financing through
March 31, 1997. The Company also executed a leasing arrangement with another
leasing company that provides for a total of $100,000 of equipment financing.
The Company leases various laboratory, manufacturing and computer equipment
under noncancelable capital leases. Terms of arrangements with the two leasing
companies contain bargain purchase provisions at the expiration of the lease
term which range from 24 months to 42 months. In some instances, the Company is
required to make a deposit of 20% of the original equipment cost which earns
interest at an annual rate of 4%. Under certain circumstances, Sepracor is the
guarantor of debt incurred to acquire equipment under the leasing facilities.
The interest rate charged on the Company's capital leases ranges from 14% to
21%.

Future minimum payments under all non-cancelable leases in effect at
December 31, 1996 are as follows:

(In thousands) Operating Capital
Year Leases Leases

1997 214 309
1998 214 316
1999 234 252

2001 236
Thereafter 515

Total minimum ------ ---
lease payments $1,649 942
------ ---

Less amount
representing interest 183
Present value of minimum
lease payments $759
----

Based on the borrowing rates currently available to the Company for capital
leases with similar terms and average maturities, the fair value of capital
leases approximates the carrying value.

The total charged to rent expense for all noncancelable leases including
amounts for building maintenance, utilities and other operating costs was
$903,000, $527,000, and $475,000 in 1996, 1995 and 1994, respectively.

In June 1994, the Company executed an agreement with a third party to
license certain technology. The Company agreed to pay license and consulting
fees of $1,200,000 payable in four equal annual installments, and royalties for
commercial sale of any product incorporating this technology to the third party
pursuant to the terms of the agreement. Through December 31, 1996, license and
consulting fees of $900,000 have been paid and charged to expense.


F-13






The Company currently buys all of its blood filter media from one supplier
under a supply contract. Although the supply agreement provides that should the
supplier be unable to produce the Company's required quantities, the supplier
will assist the Company in finding another source of supply, a disruption in
production from this supplier could cause a delay in manufacturing and a
possible loss in sales which would adversely affect operating results.

I. CONVERTIBLE SUBORDINATED NOTE PAYABLE:

In January 1997, the Company entered into a Restructuring Agreement of the
debt related to the Denmark Acquisition. Pursuant to the Restructuring
Agreement, approximately $23,000,000 of indebtedness owed to Novo Nordisk was
restructured by way of issuance by the Company to Novo Nordisk of a 12%
convertible subordinated promissory note in the principal amount of
approximately $11,700,000, which is due and payable on December 31, 2001, with
interest payable quarterly (provided that up to approximately $3,000,000 may be
forgiven in certain circumstances). Approximately $8,500,000 of the reduction of
such indebtedness was forgiven. The remainder of the reduction represents a net
amount due from Novo Nordisk to the Company related to various service
arrangements between the two companies. The amount included in the balance sheet
at December 31, 1996 includes the effect of the Restructuring Agreement net of
the $3,000,000 contingency amount to reflect the most probable result of the
Company's decision to exit the plasma business. All amounts outstanding under
such note are convertible by either party, commencing January 1998, into shares
of Common Stock at a conversion price equal to $10.50 per share.

J. SEGMENT INFORMATION:

The Company operates exclusively in the blood purification business, which
the Company considers to be one business segment.

Revenues from significant unaffiliated customers are as follows:

Year Ended December 31: 1996 1995 1994
---- ---- ----
A. 18%
B. 36% 18%
C. 83%


K. STOCKHOLDERS' EQUITY:

Stock Option Plans

Statement of Financial Accounting Standards No. 123, "Accounting for
Stock-Based Compensation", (SFAS No. 123), encourages, but does not require
companies to record compensation cost for stock-based employee compensation
plans at fair value. The Company has chosen to continue to account for
stock-based compensation using the intrinsic value method prescribed in
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees," and related interpretations. Accordingly, compensation cost for
stock options is measured as the excess, if any, of the quoted market price of
the Company's stock at the date of the grant over the amount an employee must
pay to acquire the stock.

The Company has two stock options plans currently in effect under which
future grants may be issued: the 1994 Stock Option Plan and the 1994 Director
Option Plan. A total of 2,750,000 shares has been authorized by the Company for
grants of options or shares, of which 309,000 are still available for grant.
Stock Options granted during 1996 and 1995 generally have a maximum term of ten
years and vest ratably over a period of two to five years.

The weighted average fair value at date of grant for options granted
during 1996 and 1995 was $8.77 and $2.98 per option, respectively. The fair
value of these options at date of grant was estimated using the Black-Scholes
model with the following weighted average assumptions for 1996 and 1995,
respectively: risk-free interest rate of 6.20% and 6.30%; dividend yields of 0%
for both years; volatility factor of the expected market price of the Company's
common stock of 75% for both years; and a weighted average expected life of the
options of 6 years.

F-15







During 1994 and prior to the Company's initial public offering, options to
purchase 482,000 shares of Common Stock were granted under the Plans at an
exercise price of $2.00 per share. The estimated fair market value on the date
of grant was $4.00 per share. The Company recorded compensation expense of
$197,000, $199,000 and $195,000 in 1996, 1995 and 1994, respectively, related to
these options.

In 1995, HemaSure adopted the 1995 Employee Stock Purchase Plan (the
"Stock Purchase Plan"). Under the Stock Purchase Plan, an aggregate of 100,000
shares of common stock may be purchased by employees at 85% of market value on
the first or last day of each six month offering period, whichever is lower,
through accumulation of payroll deductions ranging from 1% to 10% of
compensation as defined, subject to certain limitations. Options were exercised
to purchase 17,793 shares for a total of $165,000 during the year ended December
31, 1996 and 10,681 shares for a total of $58,000 during the year ended December
31, 1995. At December 31, 1996, 71,346 shares of common stock were reserved for
future issuance under the plan.

Had compensation cost for the Company's stock option plans been determined
based on the fair value at the grant date for awards in 1996 and 1995 consistent
with the provisions of SFAS No. 123, the Company's net income and net income per
share would have been reduced to the pro forma amounts indicated below. The
application of SFAS No. 123 to this employee stock purchase plan would not
result in a significant difference from reported net income and earnings per
share.


1996 1995
---- ----

Net income - as reported $(40,598) $(7,450)
Net income - pro forma $(43,280) $(7,750)
Net income per share - as reported $ (5.03) $ (1.20)
Net income per share - pro forma $ (5.36) $ (1.25)


The pro forma effect on net income for 1996 and 1995 is not representative
of the pro forma effect on net income in future years because it does not take
into consideration pro forma compensation expense related to grants made prior
to 1995.

In connection with the initial public offering, the Company granted to the
Underwriter an option to purchase 217,500 shares of Common Stock at an exercise
price equal to 150% of the initial public offering price or $10.50 and subject
to adjustment in certain circumstances. The option is exercisable at any time or
from time to time after April 14, 1995 and before April 14, 1999. The option may
be transferred in whole or in part at any time under specific conditions.

Due to the uncertainty surrounding the realization of the favorable tax
attributes in future tax returns, the Company has placed a valuation allowance
against its otherwise recognizable net deferred tax assets.

The Company's statutory and effective tax rates were 34% and 0%,
respectively, for both 1995 and 1994. The effective tax rate was 0% due to a net
operating loss and the nonrecognition of any net deferred tax asset. At December
31, 1996, the Company had net operating loss carryforwards (NOLs) of
approximately $26,086,000 available to offset future regular taxable earnings.
The net operating loss carryforwards expire at various dates through 2011. Tax
credit carryforwards expire at various dates from 2009 through 2011.

M. EMPLOYEES' SAVINGS PLAN:

The Company adopted a 401(k) savings plan for all domestic employees in
1994. Under the provisions of the plan, employees may voluntarily contribute up
to 20% of their compensation subject to statutory limitations. In addition, the
Company can make a matching contribution at its discretion. In 1996, the Company
provided approximately $90,000 of matching contributions. There were no employer
contributions to the plan in 1995 or 1994.

N. LITIGATION:

The Company is a defendant in two lawsuits brought by Pall Corporation
("Pall"). In complaints filed in February 1996 and November 1996, Pall alleged
that the Company's manufacture, use and/or sale of the LeukoNet product
infringes upon three patents held by Pall.

On October 14, 1996, in connection with the first action concerning
U.S. Patent No. 5,451,321, the Company filed a motion for summary judgment of
noninfringement. Pall filed a cross motion for summary judgment of infringement
at the same time. The parties are awaiting the Court's decision.

With respect to the second action concerning U.S. Patent Nos. 4,340,479
(the "'479 patent") and 4,952,572 (the "'572 patent"), the Company has answered
the complaint stating that it does not infringe any claim of the asserted
patents. Further, the Company has counterclaimed for declaratory judgment of
invalidity, noninfringement and unenforceability of the '572 patent, and a
declaratory judgment of noninfringement of the '479 patent, as a result of a
license.

The Company believes, based on advice of its patent counsel, that a
properly informed court should conclude that the manufacture, use and/or sale by
the Company or its customers of the present LeukoNet product does not infringe
any valid enforceable claim of the three asserted Pall patents. However, there
can be no assurance that the Company will prevail in the pending litigations,
and an adverse outcome in a patent infringement action would have a material
adverse effect on the Company's future business and operations.

On November 1, 1996, the Company filed a complaint in the Supreme Court,
State of New York, County of New York, against Pharmacia & Upjohn, Inc. In its
complaint, the Company seeks to receive damages arising out of the alleged
breach by Pharmacia & Upjohn ("P&U") of an agreement to sell to the Company
P&U's plasma pharmaceutical business located in Stockholm, Sweden. The complaint
seeks compensatory, consequential and punitive damages. There can be no
assurance that the Company will prevail in this litigation or, if the Company
docs so prevail, as to the amount of damages, if any, that will be awarded or
that the Company may collect.
