                                     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  technologies  to
develop  products to increase the safety of donated blood and to improve certain
blood  transfusion  and  collection  procedures.  The Company is developing  the
following products for use by blood centers, hospital blood banks and hospitals:

         o        The Red Cell  Leukoreduction  System  (the "r\LS  System")  is
                  designed for use by blood centers and hospital  blood banks to
                  remove harmful leukocytes (white blood cells) from donated red
                  blood cells.

         o        The  LeukoVir-MB-Filter  is designed for use by blood  centers
                  and  hospital  blood banks 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.

         o        The  Platelet  Leukoreduction  Filtration  System  (the  "p\LS
                  System") is designed for use by hospitals to remove leukocytes
                  from pooled donor platelet concentrates.

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-

<PAGE>



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.

         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

Red Blood Cell Systems

         r\LS System

         The Company's r\LS System is being designed for leukocyte filtration by
blood centers and hospital blood banks 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 r\LS 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 high
volume,  centralized  processing  in a regional  blood center  environment.  The
Company is focusing  its  marketing  efforts  exclusively  on blood  centers and
hospital blood banks for pre-storage leukocyte reduction.



                                       -2-

<PAGE>



         The  Company  expects  to  file an  application  for  510(K)  premarket
notification  clearance  with respect to its r\LS System with the United  States
Food and Drug Administration (the "FDA") in 1998. There can be no assurance that
the r\LS System will receive the necessary regulatory approval or achieve market
acceptance.

         While the Company  believes that the performance and ease-of-use of the
r\LS System will compare  favorably with other blood filtration  devices,  there
can be no  assurance  that the  performance  or price of the r\LS System will be
sufficient to achieve  significant  sales,  particularly in view of the dominant
position in the market held by Pall Corporation. See "-- Competition."

         LeukoNet System

         In December  1994,  the Company filed a 510(k)  premarket  notification
clearance with the FDA for the LeukoNet Pre-Storage  Leukoreduction  System (the
"LeukoNet System"), the Company's first generation leukoreduction 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. In February 1998,  the Company  determined
to discontinue  manufacturing the LeukoNet System and focus on the completion of
development and market introduction of the r\LS System.

         Sales of the  Company's  LeukoNet  System  to the  American  Red  Cross
Biomedical  Services  accounted for 86% of the Company's  total revenues in 1997
and 83% of the Company's total revenues in 1996.

Plasma System

         LeukoVir-MB Filter

         The Company  expects to  complete  clinical  trials of its  LeukoVir-MB
Filter in Europe in 1998.  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  however  that the  LeukoVir-MB  Filter will
receive marketing approval or achieve market acceptance.

Platelet System

         p\LS System

         Platelets  are  a  cellular   component  of  peripheral   blood,   used
therapeutically to prevent bleeding. There are two sources of platelets:

         1.       Pooled  platelets,  a by-product  of whole blood  donation and
                  subsequent component preparation, and

         2.       Single  donor  platelets  produced  by  a  platelet  apheresis
                  procedure and typically leukoreduced at that time.

         Pooled  platelets  (from whole  blood)  account for  approximately  4.4
million transfusions worldwide.  Anywhere from 30% (Asia-Pacific) to 70% (United
States) of these pooled platelets are leukoreduced.

         The p\LS  System is  designed to remove  leukocytes  from pooled  donor
platelet  concentrates.  The  Company  is  engaged  in  preliminary  discussions
pertaining to a cooperative  agreement  with a  manufacturer  of  leukoreduction
medium for platelets.  This medium has been  extensively  used in Europe and the
Near East for platelet leukoreduction.

         The  Company  expects  to  file an  application  for  510(K)  premarket
notification  clearance  with the FDA and  introduce the product for sale in the
United States in 1998. There can be no assurance,  however, that the p\LS System
will receive the necessary regulatory approval or achieve market acceptance.

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. 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
were attributable to sales of these non- blood related membrane filter products.
Revenues  from  these  products  were  $13,000  and  $517,000  in 1996 and 1995,
respectively.

         In 1996 and 1995,  sales to Sepracor with respect to membrane  products
accounted for 2% and 57% of the Company's total revenues, respectively. Revenues
from the U.S. Department of the Army related


                                       -4-

<PAGE>



to such products  represented  7% and 36% of the Company's  revenues in 1996 and
1995, respectively. The Company's agreement with the U.S. Department of the Army
concluded in 1996.

Technologies

         The   Company's   planned   products  are  based  on  its   proprietary
technologies  in the areas of  affinity  separations,  membrane  technology  and
device design and fabrication.

         Affinity Separations

         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.

         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  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.



                                       -5-

<PAGE>



         The  Company  has  undertaken  preliminary  studies  on the  use of its
proprietary media in other  applications such as the removal of tumor cells from
peripheral stem cell preparations and in whole blood leukoreduction.

Research and Development Expenses

         Research and development  expenses were $3,577,000 in 1997,  $6,128,000
in 1996 and $4,061,000 in 1995.  The decrease in 1997 is primarily  attributable
to a decrease in expenses associated with the Company's SteriPath Blood Pathogen
Inactivation  System,  which program was  discontinued  in 1997. The increase in
1996 over the amounts  expended in 1995 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.

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
processed 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.  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 its determination to exit 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: (i) $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; (ii) approximately  $13,000,000 was to be payable from time to time upon
the 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;  and (iii)  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 would 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 was due and payable on December 31, 2001 (the
"Note"),  with interest  payable  quarterly  (provided that up to  approximately
$3,000,000 would 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 January 6, 1998,
the Company elected to convert all indebtedness under the Note,  pursuant to the
terms thereof,


                                       -6-

<PAGE>



into shares of Common Stock of the Company at a conversion price equal to $10.50
per share, or 827,375 shares.  Pursuant to a registration rights agreement,  the
Company previously granted Novo Nordisk certain registration rights with respect
to any shares of Common Stock  acquired by Novo Nordisk upon  conversion  of the
Note.  Novo Nordisk has  contested  the  conversion  of the Note,  including the
forgiveness of the $3,000,000  amount. The Company believes that such claims are
without merit.

         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  enhancement  of a  number  of  filtration
practices  based on the  Company's  core  technology  including  red blood  cell
leukoreduction,  leukocyte recovery, platelet filtration, whole blood filtration
and  tumor  cell  filtration.  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. Pursuant to that agreement,
the Company  agrees to  indemnify  the ARCBS  against  all  losses,  damages and
liabilities  incurred  for,  among other things,  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
proposed  products.  The Company's proposed  products,  if commercialized,  will
compete  with other  products  currently  on the  market as well as with  future
products  developed  by  other  medical  device  companies'   biotechnology  and
pharmaceutical companies, hospital supply companies, national 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 are significantly larger
than the Company, have greater experience in preclinical testing, human clinical
trials  and other  regulatory  approval  procedures.  In  addition,  many of the
Company's  competitors have access to greater capital and other  resources,  may
have management  personnel with more experience than that of the Company and may
have other  advantages  over the Company in conducting  certain  businesses  and
providing certain services.  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-


                                       -7-

<PAGE>



standing relationships with the national and regional blood centers to which the
Company will market its  products.  There can be no  assurance  that the Company
will be able to compete effectively against such companies.

         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.

         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  entered into a Technology  Transfer and License  Agreement
with Sepracor under which Sepracor  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.  The Technology  Transfer and
License  Agreement expired on January 1, 1998 pursuant to its terms. The Company
does not expect such  termination  to have a material  effect upon its business,
future  operating  results or financial  condition.  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 21 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, nine patents have been issued to the Company (which expire
at various dates from 2011 through 2017).



                                       -8-

<PAGE>



         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. See Item 3, "Legal Proceedings."  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. See Item 3, "Legal Proceedings."

         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


                                       -9-

<PAGE>



the labeling of the finished product,  tracing of consignees after  distribution
and follow-up and reporting of complaint information.

         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 in the U.S.,  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  products as
medical devices.

Manufacturing and Facilities

         The Company's facilities consist of approximately 30,000 square feet of
leased  office,  laboratory  and  manufacturing  space in a modern  facility  in
Marlborough,  Massachusetts.  The Company  believes  that these  facilities  are
adequate and suitable for its needs through 1998. 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  1998.  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.

         In January 1998, the Company received ISO 9001 Registration,  which was
awarded  by  Bureau  Veritas  Quality  International.  The ISO  9000  Series  of
international  standards was  developed by the  International  Organization  for
Standardization  to promote  homogeneous  quality  processes  through the global
trade  community.   ISO  9001  specifically   addresses   requirements  for  the
manufacture, design, development, installation and service of 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, 1998, the Company employed a total of 45 persons of whom
13 were in research and development,  19 were in  manufacturing  and development
support  and 13  were  in  sales  and  administration.  Three  of the  Company's
employees hold Ph.D. degrees.

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. As of January 31, 1998,  Sepracor owned 33% 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.

         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 7, "Management's Discussion and Analysis of Financial Condition and Results
of Operations -- Results of Continuing Operations."

         Registration Rights. Beginning in April 1998, Sepracor will be entitled
to certain rights with respect to the  registration  under the Securities Act of
1933, as amended,  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.

         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 30,000 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).  The Company believes that these
facilities  are adequate and suitable for its needs  through  1998.  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.


                                      -11-

<PAGE>


         On October 14, 1996,  in  connection  with the first action  concerning
U.S.  Patent No.  5,451,321,  (the "'321 Patent") the Company filed a motion for
summary  judgment  of  noninfringement.  Pall filed a cross  motion for  summary
judgment of infringement at the same time.

         In October  1997,  the  Eastern  District  of New York  granted in part
Pall's  summary  judgment  motion  relating to the '321 patent.  The Company has
agreed to terminate the manufacture,  use, sale and offer for sale of the filter
subject to the  court's  order.  The court has not yet ruled on the  validity of
Pall's  '321  patent  claims,  which  HemaSure  has  asserted  are  invalid  and
unenforceable. No date has been set for the proceeding to determine the validity
and enforceability of Pall's '321 patent claims.

         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. Pall has attempted to withdraw the '479 patent from the second action.

         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 P&U. In its complaint, the
Company sought 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.  In  September  1997,  the Company  reached an  out-of-court
settlement with P&U. The terms of settlement included a cash payment to HemaSure
and the  granting  of an option to P&U to  license,  on a  non-exclusive  basis,
certain  intellectual  property  held by  HemaSure  Inc.  and  its  subsidiaries
relating  to plasma  fractionation.  The cash  payment was  recognized  as other
income in the third quarter ended September 30, 1997.

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, 1997.

Mr. John F. McGuire
9 Glennon Farm Lane
Tewksbury, NJ  08833

Dear Jack:

On behalf of the Board of Directors of HemaSure, and contingent upon approval of
the Board, I am delighted to extend to you our offer for the position of
President, Chief Executive Officer, and Director of HemaSure.

In this role, you will report directly to the Board of Directors of the Company.
You will have overall responsibilities for all aspects of the Company, including
the development and execution of strategic, operating, and financing plans.

Your compensation in this role will include a base salary of $14,583 per month,
with an annual bonus of $75,000, earned upon achievement of goals mutually
endorsed by the Compensation Committee and you.

In addition, you will be granted an option to purchase 600,000 shares of
HemaSure Common Stock, "the initial grant". The exercise price of the options
will be the "low" as quoted on the Nasdaq for the week ended April 4, 1997.
These options will vest over four years in equal installments of 25% commencing
on your first anniversary of employment.

An additional 200,000 shares of incentive stock options will be granted at the
earliest possible date in fiscal 1988. The Options will begin to vest upon
achievement of certain three-year "stretch" goals (see Exhibit A, attached)
which will be mutually agreed to by you and the Committee and will vest over
four years in equal installments of 25%. The exercise price will be the lower of
the fair market price on the date of the grant or the exercise price established
for "the initial grant".

In the event of a consolidation or merger or sale of all or substantially all of
the assets of the Company, in no event will you receive less than $1.00 per
share then exercisable upon the event.

The Company agrees to cover all direct relocation costs up to a maximum of $70K,
including reasonable house-hunting trips, moving of household goods, real estate
fees, and temporary housing for the first three months. In addition, in the
event you are unable to sell your New Jersey home within a reasonable period of
time after commencing employment, HemaSure will continue to pay the mortgage on
your New Jersey home until sold after you have relocated to Massachusetts.

In the event you are terminated other than for cause, you will be paid up to the
equivalent of one year's salary plus the previous year's bonus, paid monthly
over the course of 12 months from time of termination, or until such time as you
have secured employment in an equivalent role.

Jack, I truly feel that you are uniquely qualified for this role. I am genuinely
excited about working closely together with you to create an exciting and
successful company at HemaSure.

Please acknowledge your acceptance of this position and the terms of this
agreement by signing below and returning one signed original to me.

Best regards,

/s/  Timothy J. Barberich

         Settlement Agreement, withdraw the pending action against Pharmacia
         with prejudice. Pharmacia and HemaSure shall bear their own legal fees,

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 Inc. ("Sepracor"). Effective as of January 1, 1994, in
exchange for 3,000,000 shares of common stock, $.01 par value, of the Company
(the "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. As of January 31, 1998, Sepracor owned
approximately 33% 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 and $517,000 in 1996 and
1995, respectively. In June 1995, the Company received clearance from the United
States Food and Drug Administration (the "FDA") for the LeukoNet System, a
medical device designed for the removal of contaminating leukocytes from donated
blood. Fiscal 1996 was the first full year of commercial sale of its LeukoNet
System. In February 1998, the Company determined to discontinue manufacturing
the LeukoNet System and focus on the completion of development and market
introduction of its next-generation red cell filtration product. All 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 and its ability to raise capital through strategic
partnerships, public or private equity and/or debt financing.

         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 space it
occupied. 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 with a third party 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 "Denmark Acquisition") the
plasma product unit of Novo Nordisk A/S, a Danish company ("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 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 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."

Results of Continuing Operations

         Revenues were $2,357,000 in 1997, $779,000 in 1996 and $834,000 in
1995. All of the Company's revenues in 1997 were from the sale of the LeukoNet
System. Revenues from product sales to Sepracor, a related party, as a
percentage of total revenues were 2% in 1996 and 57% in 1995 and represent the
sale of membrane filter products. Product sales to Sepracor were 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 were at cost
while product sales to Sepracor for subsequent sale or lease to third parties
were 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 1997, 1996 and 1995, one customer represented 86%, 83% and 36% of total
revenues, respectively.

         The cost of products sold was $4,158,000 in 1997, $3,785,000 in 1996
and $1,073,000 in 1995. 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. Cost of products sold in 1997 includes a
charge of approximately $800,000 related to the Company's determination to
discontinue manufacturing the LeukoNet System and to focus exclusively on its
next-generation red cell filter.

         The cost of collaborative research and development was $41,000 in 1996
and $283,000 in 1995. 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.

         Research and development expenses were $3,577,000 in 1997, $6,128,000
in 1996 and $4,061,000 in 1995. The decrease in 1997 is primarily attributable
to a decrease in expenses associated with the Company's SteriPath


                                       10
<PAGE>


Blood Pathogen Inactivation System which program was discontinued in May 1997.
The increase in 1996 over the amounts expended in 1995 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 $4,964,000 in 1997,
$8,069,000 in 1996 and $3,881,000 in 1995. The 1996 expense 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." These costs did not recur
in 1997 and are the primary reason for the decrease in 1997 from 1996. The
increase in 1996 over 1995 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. Sales and marketing
costs may increase in future periods from current levels as the Company
continues its efforts to market and launch sales of its blood filtration
products.

         In April 1997, the Company determined to focus management resources on
its core business of blood filtration technologies, consistent with its earlier
decision to exit the plasma business. In connection therewith, four officers
were relieved of their duties. The Company incurred a one-time restructuring
charge of $1,215,000 in 1997 for severance and related charges in connection
with this action. At December 31, 1997 there was a balance of $437,000 remaining
to be paid related to this charge.

         Interest income in 1997, 1996 and 1995 primarily represents interest
earned on available cash and marketable securities balances during those
periods.

         The increase in interest expense in 1997 compared to 1996 and 1995 is
primarily attributable to a convertible subordinated note payable that was not
in existence during either 1996 or 1995.

         In September 1997, the Company reached an out-of-court settlement with
P&U 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
terms of settlement included a cash payment to the Company and the granting of
an option to P&U to license, on a non-exclusive basis, certain intellectual
property held by the Company and its subsidiaries relating to plasma
fractionation. The cash payment was recognized as other income in 1997 and
represents the majority of the amount in other income for that year.

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.

         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 was due and payable on December 31, 2001, with
interest payable quarterly (provided that up to $3,000,000 would be forgiven in
certain circumstances). Approximately $8,500,000 of the reduction of such
indebtedness was forgiven. The remainder of the reduction represented 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 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 reflected
management's assessment of the most probable outcome from this decision, is net
of the $8,500,000 forgiveness of indebtedness and assumed the $3,000,000
forgiveness contingency. In December 1997, the Company notified the holder of
the note of its intent to convert in January 1998, $8,687,000 of debt, which it
believes was the entire amount outstanding as of the date of conversion. On
January 6, 1998, the Company converted the note, pursuant to its terms, into
shares of Common Stock at a conversion price of $10.50 per share, or 827,375
shares. The holder of the note has contested the conversion of the note,
including the forgiveness of the $3,000,000 amount. The Company believes that
such claims are without merit.

New Accounting Standards

         In June 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 130, "Reporting Comprehensive Income"
(SFAS 130). SFAS 130 requires the reporting and display, in a full set of
general purpose financial statements, of all items that are required to be
recognized under accounting standards as components of comprehensive income.
SFAS 130 is effective for statements issued for periods beginning after December
15, 1997 and reclassification of financial statements for earlier periods for
comparative purposes is required. Management believes that the adoption of SFAS
130 will not have a material impact on the Company's financial statements.

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 "'321 patent"), the Company filed a motion for
summary judgment of noninfringement. Pall filed a cross motion for summary
judgment of infringement at the same time.

         In October 1997, the Eastern District of New York granted in part
Pall's summary judgment motion relating to the '321 patent. The Company has
agreed to terminate the manufacture, use, sale and offer for sale of the filter
subject to the court's order. The court has not yet ruled on the validity of
Pall's '321 patent claims, which the Company has asserted are invalid and
unenforceable. No date has been set for the proceeding to determine the validity
and enforceability of Pall's '321 patent claims.

         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. Pall has attempted to withdraw the '479 patent from the second action.

         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 could have a material
adverse effect on the Company's financial condition and 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 P&U. In its complaint, the
Company sought 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. In September 1997, the Company reached an out-of-court
settlement with P&U. The terms of settlement included a cash payment to the
Company and the granting of an option to P&U to license, on a non-exclusive
basis, certain intellectual property held by the Company and its subsidiaries
relating to plasma fractionation. The cash payment was recognized as other
income in 1997.

Liquidity and Capital Resources

         The net decrease in cash and cash equivalents in 1997 was $4,081,000.
This net decrease is attributable to net cash used in operating activities of
$8,391,000 offset in part by net cash provided by investing activities of
$4,265,000.

         Net cash used in operating activities is primarily attributable to the
net loss of $9,884,000, an increase in accounts receivable of $153,000 and a
reduction in accounts payable of $736,000 offset in part by a decrease in
inventories of $218,000, impairment of assets of $475,000 in conjunction with
the determination to discontinue manufacture of the LeukoNet System,
depreciation and amortization of $859,000, an increase in accrued expenses of
$273,000, and the receipt of $500,000 related to the net assets of discontinued
business. Net cash provided from investing activities relates to
available-for-sale marketable securities investing activities of $4,483,000
offset in part by additions to property and equipment of $220,000.

         The Company believes, based on its current operating plan, that, in
addition to its available cash balances, it will need additional financing in
order to fund the Company's operations beyond the first half of 1998. Possible
sources of capital include strategic partnerships, public or private equity
and/or debt financing, all of which the Company is pursuing. No assurance can be
given, however, that the Company will be able to obtain additional financing on
terms acceptable to the Company, if at all.

         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 was
due and payable on December 31, 2001, with interest payable quarterly (provided
that up to approximately $3,000,000 would 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 represented a net amount due from Novo Nordisk


                                       12
<PAGE>


to the Company related to various service arrangements between the two
companies. The amount included in the balance sheet at December 31, 1997 and
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 were
convertible by either party, commencing January 1998, into shares of Common
Stock at a conversion price equal to $10.50 per share. In December 1997, the
Company notified the holder of the note of its intent to convert in January
1998, $8,687,000 of debt, which it believes was the entire amount outstanding as
of the date of conversion. On January 6, 1998, the Company converted the note,
pursuant to its terms, into shares of Common Stock at a conversion price of
$10.50 per share, or 827,375 shares. The holder of the note has contested the
conversion of the note, including the forgiveness of the $3,000,000 amount. The
Company believes that such claims are without merit.

         In March 1997, the Company exercised its right, under the lease
arrangement of its Marlborough, Massachusetts facility, to have a portion of its
leasehold improvements financed and received $140,000 in connection with this
arrangement. This amount will be repaid in 60 equal monthly installments at a
rate of 12% per annum. As of December 31, 1997, there was a balance of $109,000
remaining to be paid on this note.

         In April 1997, the Company determined to focus management resources on
its core business of blood filtration technologies, consistent with its earlier
decision to exit the plasma business. In connection therewith, four officers
were relieved of their duties. In connection therewith, the Company incurred a
one-time charge of $1,215,000 in 1997 related to these actions. At December 31,
1997 there was a balance of $437,000 remaining to be paid related to this
charge.

         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
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, 1997, all license and
consulting fees pursuant to that agreement have been paid and charged to
expense.

         In 1994, in collaboration with Sepracor and certain of its other
subsidiaries, the Company executed an equipment leasing arrangement that
provided for a total of $2,000,000 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 the Company only with the same leasing
company providing $1,100,000 of equipment lease financing. This arrangement
terminated in March 1997. All amounts outstanding under the 1994 leasing
facility are being repaid under the original terms of that leasing arrangement.
There was $556,000 outstanding under all leasing arrangements as of December 31,
1997.

Future Operating Results

         Certain of the information contained in this Annual Report, including
information with respect to 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:

         The Company believes that the performance of its blood-related products
will be competitive with products sold by other vendors of blood filtration and
transfusion products and may encounter intense competition in the sale of such
products from biotechnology, pharmaceutical and hospital supply companies. 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 are significantly larger than the
Company, have greater experience in preclinical testing, human clinical trials
and other regulatory approval procedures. In addition, many of the Company's
competitors have access to greater capital and other resources, may have
management personnel with more experience than that of the Company and may have
other advantages over the Company in conducting certain businesses and providing
certain services. There can be no assurance that the Company will be able to
compete effectively against such companies. Pall, 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 certain
patents held by Pall.

         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.

         In June 1995, the Company received clearance from the FDA for the
LeukoNet System. Fiscal 1996 was the first full year of production of the
LeukoNet System and all of the Company's revenues in 1997 were from such
product. In February 1998, the Company determined to discontinue manufacturing
the LeukoNet System and


                                       13
<PAGE>


focus on the completion of development and market introduction of its
next-generation red cell filtration product. There can be no assurance however
that the Company will successfully complete the development and
commercialization of this product, or that such product will be accepted by
potential customers in the marketplace.

         All of the Company's planned blood filtration and transfusion products
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
1998. 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 and transfusion products
may require preclinical and clinical testing prior to submission of any
regulatory application for commercial use. The Company expects to receive
regulatory approval for its next-generation red cell filter before the end of
1998. 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 1998.

         Until relatively recently, computer designs that used microprocessors
had consistently abbreviated dates by eliminating the first two digits of the
year under the assumption that these two digits would always be 19. As the year
2000 approaches, such systems will be unable to accurately process certain
date-based information. This problem is commonly referred to as "the Year 2000
Issue." Management is in the process of assessing the implications of the Year
2000 Issue on its information and other systems, and those of its vendors and
other relationships. The Company currently believes that with modifications to
existing software and/or conversions to new software, the Year 2000 Issue will
not have a significant adverse effect on its information and other systems or on
its business, nor will it result in a significant commitment of resources to
resolve potential problems associated with this event.

         The Company  believes,  based on its current  operating plan,  that, in
addition to its available cash balances,  it will need  additional  financing in
order to fund the Company's  operations beyond the first half of 1998.  Possible
sources of capital  include  strategic  partnerships,  public or private  equity
and/or debt financing, all of which the Company is pursuing. No assurance can be
given,  however, that the Company will be able to obtain additional financing on
terms  acceptable to the Company,  if at all.  Should the Company fail to obtain
any such  financing,  or to obtain  such  financing  on terms  favorable  to the
Company,  the Company may be unable to continue or complete the  development  of
its proposed products and/or market such products  successfully,  or to continue
its current  operations as presently  conducted,  if at all. 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.

         Because of the foregoing factors, past financial results should not be
relied upon as an indication of future performance. The Company believes that
period-to-period comparisons of its financial results to date are not
necessarily meaningful and 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, 1997 and 1996, and the related consolidated
statements of operations, stockholders' equity (deficit), and cash flows for
each of the three years in the period ended December 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
HemaSure Inc. as of December 31, 1997 and 1996, and the consolidated results of
its operations and its cash flows for each of the three years in the period
ended December 31, 1997 in conformity with generally accepted accounting
principles.

         The accompanying financial statements have been prepared assuming that
the Company will continue as a going concern. As discussed in Note A to the
financial statements, the Company has suffered recurring losses from operations
and has a stockholders' deficit that raise substantial doubt about its ability
to continue as a going concern. Management's plans in regard to these matters
are described in Note A. The financial statements do not include any adjustments
that might result from the outcome of this uncertainty.

HemaSure Inc.
Notes to Consolidated Financial Statements

A.   The Company

Nature of the Business

     HemaSure Inc.  (the  "Company")  is utilizing  its  proprietary  filtration
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 Inc.  ("Sepracor"),  a related  party,  for use in chemical  processing
applications.  Subsequently  and  throughout  1997,  the  Company's  revenue was
derived from the  commercial  sales of its  LeukoNet  System,  a medical  device
designed for the removal of  contaminating  leukocytes  from donated  blood.  In
February 1998, the Company determined to discontinue  manufacturing the LeukoNet
System and focus on the completion of development and market introduction of its
next-  generation  red cell  filtration  product.  The  Company's  collaborative
research and  development  efforts in 1995 and 1996 were with the United  States
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 regulations
of the United States Food and Drug Administration and similar foreign regulatory
authorities and agencies.

     Since its  inception,  the  Company  has  suffered  recurring  losses  from
operations,  accumulated  deficits  and at  December  31, 1997 had a net capital
deficiency.  These  conditions  raise  substantial  doubt  about its  ability to
continue as a going  concern.  The ultimate  success of the Company is dependent
upon its ability to raise  capital  through  strategic  partnerships,  public or
private  equity  and/or debt  financing and the proposed  introduction  of a new
product into the market.  However, the Company's capital requirements may change
depending  upon  numerous   factors,   including   compliance   with  regulatory
requirements,  the time necessary to  commercialize  the Company's  proposed new
product and the demand for the Company's  proposed product.  No assurance can be
given that the  Company  will be able to obtain  additional  financing  on terms
acceptable  to the  Company,  if at all, or that the Company  will  successfully
develop or effect the new product  introduction  into the market.  The financial
statements do not include any adjustments  that might result from the outcome of
this uncertainty.

     In view of the Company's current financial condition,  the Company plans to
manage  aggressively  its working  capital and expenses while  pursuing  product
sales opportunities, as well as strategic or other business relationships.

     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 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 the Company or a subsidiary of the
Company) and additional consideration payable in 1998 in cash or stock, at the
option of the Company, which would not be paid in certain events. The
acquisition was accounted for under the purchase method of accounting. Results
of operations performed for the Denmark Acquisition have not been presented
because the subsequent decision to discontinue the business (as described below)
eliminates any comparable continuing impact on the Company's financial
statements.

     The loss from  operations  of  discontinued  business of $9,550,000 in 1996
reflects  the loss from the date of the  acquisition.  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
approximately $11,700,000,  which was due and payable on December 31, 2001, with
interest payable quarterly  (provided that up to approximately  $3,000,000 would
be forgiven in certain circumstances). Approximately $8,500,000 of the reduction
of such  indebtedness  was forgiven;  such forgiveness was 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  represented a net
amount  due  from  Novo  Nordisk  to the  Company  related  to  various  service
arrangements  between the two companies.  See Note I  (Convertible  Subordinated
Note Payable) below.


                                       20
<PAGE>


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

     In April 1997, the Company determined to focus management  resources on its
core  business of blood  filtration  technologies,  consistent  with its earlier
decision to exit the plasma  business.  In connection  therewith,  four officers
were relieved of their  duties.  The Company  incurred a one-time  restructuring
charge of $1,215,000  in 1997 for  severance  and related  charges in connection
with this  determination.  At December  31, 1997 there was a balance of $437,000
remaining to be paid related to this charge.

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
$1,025,000 and $5,407,000 at December 31, 1997 and 1996,  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.

Marketable Securities

     Management determines the appropriate  classification of its investments in
debt and equity  securities  at the time of  purchase.  At December 31, 1997 and
1996, 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.

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


                                           1997                     1996
                                           ----                     ----

U.S. Government Agency Obligations      $6,882,000              $11,369,000

     The  unrealized  holding loss of available for sale  marketable  securities
approximated $1,200 as of December 31, 1997 and $2,600 as of December 31, 1996.

     All debt  securities  available  for sale at December 31, 1997 and 1996 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, 1997
and  1996,  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 10 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.


                                       21
<PAGE>


Product Sales to Related Parties

     Revenues for product sales to Sepracor are recorded at prices based on a
pricing agreement between the Company 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.

Net Loss Per Share

     Net loss per common share is based on the weighted average number of shares
of common stock  outstanding  during each period.  Common share equivalents have
not been  included  because the effect would be  antidilutive.  The common share
equivalents  of  the  Company  consist  of  stock  options  (see  Note  K) and a
convertible subordinated note payable (see Note I).

     The  Financial  Accounting  Standards  Board  (FASB)  issued  Statement  of
Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128"), which
was effective for financial  statements issued for periods ending after December
15, 1997. SFAS 128 established  standards for computing and presenting  earnings
per share  ("EPS").  This  statement  simplifies  the  standards  for  computing
earnings per share previously  found in Accounting  Principles Board Opinion No.
15,  "Earnings  Per  Share,"  and makes them  comparable  to  international  EPS
standards.  It replaces the  presentation  of primary EPS with a presentation of
basic EPS.  This  statement  requires  restatement  of all prior period EPS data
presented.  The Company adopted SFAS 128 in December of 1997, which did not have
a  significant  effect on its  financial  statements  for the  current  or prior
periods.

Income Taxes

     Deferred  income  taxes are  accounted  for  under the asset and  liability
method.  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.  A  valuation  reserve is
established  if it is more likely than not that all or a portion of the deferred
tax asset will not be realized.

     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 tax returns of Sepracor.  Additionally, based
upon the Internal Revenue Code and changes in company ownership,  utilization of
the Company's net operating loss may be subject to an annual limitation.

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, 1997 and 1996
and the  reported  amounts of  revenues  and  expenses  during  the years  ended
December  31,  1997,  1996 and 1995.  Actual  results  could  differ  from those
estimates.

Other

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" (SFAS
130). SFAS 130 requires the reporting and display, in a full set of general
purpose financial statements, of all items that are required to be recognized
under accounting standards as components of comprehensive income. SFAS 130 is
effective for statements issued for periods beginning after December 15, 1997
and reclassification of financial statements for earlier periods for comparative
purposes is required. Management believes that the adoption of SFAS 130 will not
have a material impact on the Company's financial statements.

D.    Allocations from and Agreements with Sepracor

     The Company was  formerly a  wholly-owned  subsidiary  of  Sepracor.  As of
January 31, 1998, Sepracor owned 33% of the common stock, $.01 par value, of the
Company ("Common  Stock").  Since the Company's  inception  through December 31,
1995,   all  facilities   and  support   services  of  the  Company,   including
administrative  support,  were provided by Sepracor.  For these  facilities  and
services,  the Company was charged $771,000 for 1995. These charges represent an
allocation of the Company's  proportionate  share of Sepracor's  overhead  costs
using  formulas  developed by  management  


                                       22
<PAGE>


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 on behalf of the Company.

     Under a  Corporate  Services  Agreement,  effective  from  January  1, 1994
through  December 31, 1995, the Company  received certain basic support services
from Sepracor in exchange for a fixed monthly payment,  adjusted  annually.  The
Company  recorded an expense of $244,000 for these services in 1995. 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 with a third party for its  manufacturing,
laboratory, research and office space in February 1996 (see Note H below).

     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 had granted an exclusive license to
the Company  for any  improvements  to the  transferred  technology,  which were
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 the Company  (the
"Effective Period"). The Company had 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 were  royalty-free.  Sepracor had also granted the
Company a right of first  refusal to any  product,  which  Sepracor  proposed to
sell,  or license a third party to sell  during the  Effective  Period,  for use
within the Company Field. The Technology  Transfer and License Agreement expired
on January 1, 1998  pursuant to its terms and the  Company  does not expect such
termination  to have a  material  effect  upon its  business,  future  operating
results or financial condition.

     In addition, beginning in April 1998, Sepracor will be entitled to certain
rights with respect to the registration under the Securities Act of 1933, as
amended, 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 1997 and 1996 trade receivables  primarily  represent amounts
due for product  sales.  The  allowance  for  doubtful  accounts was $25,000 and
$10,000 at December 31, 1997 and 1996, respectively.

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

F.    Inventories

      Inventories consist of the following at December 31:

      Lease Obligations

     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 commenced 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 is required to pay its allocated share of taxes and operating
costs in addition to the base annual rent. In March 1997, the Company  exercised
its right,  under the lease,  to have a portion  of its  leasehold  improvements
financed and received $140,000 in connection with this arrangement.  This amount
will be repaid in 60 equal monthly installments with an interest rate of 12% per
annum.  As of December 31, 1997 there was a balance of $109,000  remaining to be
paid on this note.

     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  $2,000,000  to these  companies  for purposes of  financing  capital
equipment.  In October 1996, the Company executed a separate follow-on equipment
leasing  arrangement  that provided  $1,100,000 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 noncancellable  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%.

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  noncancellable  leases including
amounts  for  building  maintenance,  utilities  and other  operating  costs was
$803,000, $903,000 and $527,000, in 1997, 1996 and 1995, 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. As of December 31, 1997, all license and
consulting  fees  pursuant  to that  agreement  have  been paid and  charged  to
expense.

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 was due and payable on December 31, 2001, with
interest payable quarterly (provided that up to approximately $3,000,000 would
be forgiven in certain circumstances). Approximately $8,500,000 of the reduction
of such indebtedness was forgiven. The remainder of the reduction represented 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, 1997 and 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. In December 1997, the
Company notified the holder of the note of its intent to convert in January
1998, $8,687,000 of debt, which it believes was the entire amount outstanding as
of the date of conversion. On January 6, 1998, the Company converted the note,
pursuant to its terms, into shares of Common Stock at a conversion price of
$10.50 per share, or 827,375 shares. The holder of the note has contested the
conversion of the note, including the forgiveness of the $3,000,000 amount. The
Company believes that such claims are without merit.

J.    Segment Information

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

K.    Stockholders' Equity (Deficit)

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 


                                       25

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, as amended, and the
1994 Director Option Plan, as amended (collectively, the "Plans"). A total of
2,750,000 shares has been authorized by the Company for grants of options or
shares, of which 639,000 are still available for grant. Stock Options granted
during 1997 and 1996 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
1997,  1996 and 1995 was $2.04,  $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 1997,
1996 and 1995,  respectively:  risk-free interest rate of 5.5%, 6.20% and 6.30%;
dividend  yields of 0% for all years;  volatility  factor of the expected market
price of the Company's common stock of 75% for all years; and a weighted average
expected life of the options of 5.5 years.

     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
$309,000, $197,000 and $199,000 in 1997, 1996 and 1995, respectively, related to
these options.

     In January 1998, the Company adopted a Stock Option Exchange Program.  Upon
employee  consent,  the program provides for the grant to each employee of a new
stock option in exchange for the  cancellation of the old stock option.  The new
stock  option,  granted at fair market  value at date of  issuance,  will become
exercisable for a number of shares of Common Stock equal to the number of shares
covered by the old stock option.

     In 1995,  the Company  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  42,183 shares for a total of $47,000 during the year ended December
31,  1997 and  17,793  shares  for a total of  $165,000  during  the year  ended
December 31, 1996.  At December  31,  1997,  29,163  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 1997,  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.

     The  pro  forma  effect  on net  income  for  1997,  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 1997 and 1996. The effective tax rate was 0% due to a net
operating loss and the non-recognition of any net deferred tax asset. At
December 31, 1997, the Company had federal and state tax net operating loss
carryforwards (NOLs) of approximately $43,000,000 and $42,000,000, respectively,
to offset future regular taxable earnings. The federal and state NOLs expire at
various dates through 2012 and 2002, respectively. Federal and state tax credit
carryforwards of approximately $443,000 and $319,000, respectively, expire at
various dates from 2009 through 2012. Based upon the Internal Revenue Code and
changes in company ownership, utilization of the Company's NOLs may be subject
to an annual limitation.

M.    Employees' Savings Plan

     The  Company  has a  401(k)  plan for all  domestic  employees.  Under  the
provisions of the plan, employees may voluntarily  contribute up to 15% of their
compensation subject to statutory limitations. In addition, the Company can make
a  matching  contribution  at its  discretion.  In 1997 and  1996,  the  Company
provided approximately $34,000 and $90,000 of matching contributions. There were
no employer contributions to the plan in 1995.

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 "'321 Patent"), the Company filed a motion for summary
judgment of  noninfringement.  Pall filed a cross motion for summary judgment of
infringement at the same time. In October 1997, the Eastern District of New York
granted in part Pall's summary judgment motion relating to the '321 patent.  The
Company has agreed to terminate the manufacture, use, sale and offer for sale of
the filter  subject  to the  court's  order.  The court has not yet ruled on the
validity of Pall's '321 patent  claims,  which HemaSure has asserted are invalid
and  unenforceable.  No date has been set for the  proceeding  to determine  the
validity and enforceability of Pall's '321 patent claims.

     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. Pall has attempted to withdraw the '479 patent from the second action.

     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 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 financial condition and 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 P&U. In its complaint, the
Company sought 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 sought compensatory, consequential and punitive
damages. In September 1997, the Company reached an out-of-court settlement with
P&U. The terms of settlement included a cash payment to the Company and the
granting of an option to P&U to license, on a non-exclusive basis, certain
intellectual property held by the Company and its subsidiaries relating to
plasma fractionation. The cash payment was recognized as other income in 1997.
