                                  PART I.
ITEM 1. BUSINESS

GENERAL

      INCSTAR   Corporation  and  its  subsidiaries  (the   "Company"   and
"INCSTAR") develop, manufacture, and market test kits and related  products
used  by  major hospitals, clinical reference laboratories and  researchers
involved  in  diagnosing  and  treating  immunological  conditions.   Since
December  1989,  the  Company  has been majority-owned  by  BioFin  Holding
International  B.V.  ("BFHI"), a subsidiary of Sorin Biomedica  Diagnostics
S.p.A. (Sorin) which is an Italian affiliate of Fiat, Inc. The Company  was
incorporated  in  Minnesota  in  1975 under  the  name  of  Immuno  Nuclear
Corporation. The Company's principal executive offices are located at  1990
Industrial Boulevard, Stillwater, Minnesota, 55082.
      
      On  March  10,  1997,  INCSTAR and the other parties  to  the  Merger
executed  the Agreement and Plan of Merger (the "Merger Agreement"),  among
American  Standard Inc., a Delaware corporation ("ASI"), American  Standard
Medical Systems, Inc., a Delaware corporation and a wholly owned subsidiary
of  ASI  ("ASM"),  ISTR Merger Corporation, a Minnesota corporation  and  a
wholly owned subsidiary of ASM ("Mergeco"), and INCSTAR, pursuant to  which
each share of INCSTAR Common Stock issued and outstanding immediately prior
to  the time when the Merger becomes effective, other than shares of Common
Stock   with  respect  to  which  dissenters'  rights  have  been  properly
exercised, will be converted into and become the right to receive $6.32 per
share  in  cash.  Pursuant to the Merger, Mergeco will merge with and  into
INCSTAR,   with  INCSTAR  as  the  surviving  corporation  (the  "Merger").
Consummation of the Merger is subject to the affirmative vote of a majority
of  shareholders entitled to vote at a special meeting of the  shareholders
of INCSTAR scheduled to be held in May 1997.
      
      The  Merger  Agreement has been signed concurrently with the  signing
of  the  Agreement,  dated  March 10, 1997, by and  among  Sorin  Biomedica
S.p.A.,  an  Italian  corporation, Sienna  Biotech  International  Inc.,  a
Delaware  corporation ("Sienna"), and ASI (the "European Agreement").   The
European Agreement provides for the sale to Sienna and ASI by Sorin of such
assets,  as  defined  in  the European Agreement, associated  with  Sorin's
European Diagnostics Division.
      
      Under  to the Merger Agreement the consummation of transactions under
the  European  Agreement  is  a condition to  the  closing  of  the  Merger
Agreement.
      
      It  is  currently anticipated that the Merger will be effected  prior
to June 30, 1997.
      
PRODUCTS
      
       The  Company currently markets, develops and manufactures individual
test  reagents  and  test  kits, using primarily radioimmunoassay  ("RIA"),
enzyme   immunoassay  ("EIA"),  immunoturbidimetric  assay   ("ITA")    and
immunofluorescent  assay ("IFA") technologies for clinical  diagnostic  and
medical   research  purposes.   The  Company  also  produces  and   markets
histochemical  antisera and natural and synthetic  peptides  also  used  in
clinical  diagnostic and medical research.  The Company's product focus  is
on  diagnostic tests for autoimmune, infectious disease, endocrinology  and
bone  and  mineral  metabolism product segments,  utilizing  a  variety  of
technologies.   The immunodiagnostic market is shifting  away  from  manual
testing  to  automated or semi-automated testing in  an  effort  to  reduce
laboratory  costs involved in processing medical diagnostic  tests.   As  a
result,  the research and development activities of the Company are  mainly
focused on developing non-isotopic tests that can be run on open instrument
systems  that are either currently in the customers labs, or can be  placed
there in a cost effective manner.

      DIAGNOSTIC AND RESEARCH KITS.  The Company believes that it is one of
the  largest producers of RIA products in the world.  The total RIA market,
however,  has  been significantly decreasing in recent  years  due  to  two
factors:   (1) isotopic technologies such as RIA are not easily convertible
to automated instrument testing systems and (2) disposal issues relative to
radioactive materials.  Current trends in the immunodiagnostic  market  are
to  employ  technologies such as EIA, which require less labor  to  process
test  results. Consequently, the challenge facing the Company is, and  will
continue  to be, to develop products that are non-isotopic and  amiable  to
semi and fully automated assay systems.  Although the current trend in  the
domestic  market,  and to a lesser degree in the international  market,  is
away from manual, RIA testing, the Company feels that its' strengths in RIA
manufacturing and marketing will allow it to maintain or grow its share  of
this declining market.  The Company believes that in the near-term its  RIA
products will provide it with the capital resources necessary to pursue new
research and development activities.

       RIA test procedures are used to precisely measure the extremely  low
levels  of certain hormones, peptides and other substances present  in  the
human body.  Antibodies are proteins produced by higher animals in response
to  some  foreign material, known as the "antigen," entering the  blood  or
tissue.   The  antibody protects the animal by binding to the  antigen  and
helping other body mechanisms destroy it.  When human hormones and peptides
are  injected  as  antigens into a laboratory animal, the  animal  develops
antibodies  to  eliminate the antigens.  Serum containing these  antibodies
(antiserum)  is  taken  from the laboratory animals and  processed  into  a
binding  reagent for the specific human hormone or peptide. The reagent  is
then  combined  with other reagents in a test kit to create  an  analytical
system to measure the level of that human hormone or peptide present in the
specimen to be tested.

      Precise amounts of antiserum, which act as the binder, are mixed with
radioactively-labeled (isotopic) tracer antigen and a  lower  concentration
unlabeled antigen. The tracer antigen and the unlabeled antigen compete for
binding  locations on the antibody in the antiserum. The bound  antigen  is
measured  by  a  radiation  counter and  the  level  of  bound  antigen  is
calculated.  The  results  of this controlled procedure  are  repeated  for
several concentrations of known antigen and a standard curve is plotted.  A
fluid specimen is then taken from a patient for testing and substituted for
the unlabeled antigen. The results of the competitive binding of the tracer
antigen  and  the  antigen  in the fluid specimen  are  compared  with  the
standard  curve,  and  the  precise quantity of hormone  or  peptide  being
measured  is  determined. The sensitivity and accuracy of RIA tests  depend
primarily upon the quality of the binding antisera and tracer antigen.

        The  Company  currently  markets  approximately  80  RIA  products,
primarily  used  in  the  analysis of endocrine, neuroendocrine,  bone  and
mineral metabolism, therapeutic drug monitoring and thyroid function.   The
majority  of  thyroid  function testing products  are  marketed  under  the
Clinical  Assays  trademark product line that the  Company,  together  with
Sorin,  acquired  in 1990 from Baxter International Inc. ("Baxter").   Each
RIA  kit  contains  the  following:  an  antiserum  consisting  of  primary
antibodies  and, in most cases, a reagent used to precipitate  the  primary
antigen antibody complex; a radioactively-labeled antigen to act as tracer;
a  non-radioactive  or  cold  antigen to act as  test  calibrators;  and  a
protocol booklet that provides specific test instructions.  The tracers  in
the  RIA  kits  have shelf lives of six to twelve weeks  depending  on  the
product.   The process of RIA testing requires the use of skilled labor  in
diagnostic laboratories.

      The  Company  markets  approximately 55 EIA  products  primarily  for
infectious disease and autoimmune disorders.  The basic principles  of  EIA
technology  is very similar to RIA in that a highly specific and  sensitive
reaction of an antigen and antibody must take place.  With EIA, the  result
is  measured by color development intensity rather than radioactivity.  EIA
technology  uses standard laboratory procedures and facilitates  throughput
of  large  testing  volumes such as those of a large reference  laboratory.
EIA  product  lines  include the Epstein Barr Virus ("EBV")  and  TheraTest
products,  as discussed below, and the ToRCH group of tests (toxoplasmosis,
rubella, cytomegalovirus and herpes).

       The  Company  also markets approximately 20 products  based  on  IFA
technology for infectious disease and autoimmune disorders.  The kits based
on IFA technology are employed in sophisticated diagnostic laboratories for
antibody   detection  and  semi-quantitation  in  infectious  disease   and
autoimmune  disorders.  Patient serum samples are incubated  on  microscope
slides  containing prepared antigen substrate, for example,  virus-infected
mammalian  cells.   The  antibody, if present, will bind  to  the  antigen.
After a saline rinse, which removes unbound serum, the microscope slide  is
reacted  with  a  fluorescein  conjugate  that  binds  to  antigen-antibody
complexes,  which  formed during initial incubation.   Following  a  saline
rinse,  the slides are viewed under a fluorescence microscope and  examined
for fluorescent staining on the specific antigen sites.  Immunofluorescence
kits  provide prepared multi-sample slides, positive and negative reference
serum  controls, fluorescein conjugate, buffered saline and mounting medium
as  ready-to-use stabilized reagents.  The Company's infectious disease IFA
assays  include  Toxoplasmosis, Cytomegalovirus, Herpes and a  confirmatory
test  for syphilis.  The autoimmune product offerings incorporate  a  broad
range  of  kits  and  components  intended  for  detection  of  antinuclear
antibodies  and  anti-native  DNA  antibodies  (useful  in  systemic  lupus
erythematosus testing), antimitochondrial antibody testing and  antithyroid
antibodies intended for diagnosis of primary biliary cirrhosis and  Grave's
disease, respectively.

       In  addition to the distribution of those products that the  Company
develops and manufactures, the Company is the exclusive distributor in  the
United  States  and  Canada  of  certain  of  Sorin's  hepatitis  in  vitro
diagnostic products.  Sorin has developed RIA and EIA hepatitis tests  that
are used worldwide in the diagnosis of Hepatitis A and Hepatitis B.

      SERUM  PROTEIN  MEASUREMENT.  The Company currently  markets  23  ITA
kits  for the assessment of specific human serum proteins.  Sold under  the
trade  name   "SPQ Test System," the tests are designed for use  on  common
automated  clinical chemistry analyzers.  The ITA kits are  utilized  on  a
large   number   of  different  automated  analyzers.   Consequently,   the
development  of  new instrument-specific applications  is  required  on  an
ongoing basis.  Each assay is based on the principle of immunoturbidimetric
or  immunonephelometric measurement of antigen-antibody  complexes.   These
antigen-antibody  complexes are formed when patient  samples  are  combined
with  the  specific antibody of the test kit.  As a part of  the  SPQ  Test
System,  specific  human  protein controls,  patient  sample  diluents  and
specific  antibodies  are  provided as separate products.   ITA  technology
offers  the clinical laboratory the advantages of superior speed, precision
and  automation.  Included in the ITA product line are specific assays  for
Apolipoprotein A-1, Apolipoprotein B and Lipoprotein(a), which  are  useful
in  cardiac  risk  assessment.  The remaining ITA assays in  the  SPQ  Test
System  are  used in the assessment of immunological disorders, nutritional
status, acute response and kidney failure.
      
      ANTISERA  PRODUCTS.  The antisera product lines from the Company  are
used  for the analysis of human serum proteins present in the human  serum.
Common  clinical laboratory procedures using the antisera products  include
immunofixation    electrophoresis,   immunoelectrophoresis    and    radial
immunodiffusion methods.  The techniques utilized by the laboratory  result
in  the  determination  of specific protein levels and  the  assessment  of
specific  protein components following the binding of the  antiserum  to  a
specific serum protein.  The presence of the serum protein is determined by
protein  staining  or  through the use of fluorescent  or  enzyme  staining
procedures.

       BULK  AND  CUSTOM ANTISERA PRODUCTS.  The bulk and  custom  antisera
products  produced  by  the  Company are used by major  medical  diagnostic
instrumentation  manufacturers worldwide in the  production  of  diagnostic
test kits to be used on their instruments.  The Company offers an extensive
line  of  antisera products to human serum proteins that are  monospecific,
avid,  and  of  high titer. Antisera products are produced as nephelometric
quality,  standard  antisera,  IgG  fractions  and  fluorescent  or  enzyme
conjugated preparations. The Company also produces calibrators to  be  used
as  reference  standards in conjunction with the various antisera  products
offered.

      Custom  antisera from the Company's standard supply are also produced
according  to  specifications  provided by  customers.   The  Company  also
performs  custom  immunization and development of specific antibodies  upon
customer request.
      
       HISTOCHEMICAL ANTISERA.  Unlike RIA, ITA and EIA methods, which  are
used  to  analyze  fluid samples taken from the human  body,  histochemical
antisera are utilized in an in vitro procedure to determine the presence of
hormones or peptides in body tissue.  A histochemical antiserum is used  as
a  binding  reagent for a specific hormone or peptide.   Once  binding  has
occurred,  the  presence  of  the  hormone  or  peptide  is  determined  by
fluorescent or enzyme staining procedures performed on the tissue specimen.
The  Company's  histochemical products are used in clinical  diagnoses  and
medical  research,  frequently  in  conjunction  with  RIA,  ITA   or   EIA
technologies.
      
RECENT DEVELOPMENTS
      
      During  the fourth quarter of 1996 the Company announced its  receipt
of  Food and Drug Administration ("FDA") approval for its second generation
tests   for   the   detection   of   the  infectious   diseases,   rubella,
cytomegalovirus  ("CMV")  and herpes simplex.   These  products  have  been
marketed  in  Europe for several years through the Company's affiliate  and
have  been  widely accepted as the gold standard in the industry,  offering
high sensitivity and ease of use.
      
      Also  during  the fourth quarter, the Company received  FDA  approval
for  its  25-OH-D  RIA assay, the first test method on  the  market  to  be
cleared  by  the  FDA  for  the  detection of 25-Hydroxyvitamin  D  in  the
bloodstream.  This detection is becoming an increasingly important tool  to
determine levels of vitamin D, which is necessary for the body's metabolism
of calcium.
      
      During  the  second  quarter  of  1995  the  Company  announced   the
completion  of  the  manufacturing transfer  of  its  TheraTest1  trademark
product  line  of  diagnostic assays to its Stillwater  facility.   INCSTAR
acquired this FDA-cleared EIA panel of autoimmune diagnostic assays in  May
1994  from TheraTest Laboratories, Inc. of Chicago.  The TheraTest products
are  used  as a confirmatory test for the diagnosis of rheumatoid arthritis
and  other  connective tissue diseases such as systemic lupus erythematosus
and  scleroderma.   The TheraTest products are also  an  extension  of  the
Company's  existing  immunofluorescence  autoimmunity  product   line   and
complement the Company's EIA product offerings.
      
      Also  during the second quarter of 1995 the Company received approval
from  the FDA for its second generation EBV diagnostic tests.  EBV  is  the
causative  agent  of  infectious mononucleosis, and  can  cause  lymphomas,
chronic fatigue syndrome and a variety of other diseases in patients with a
weakened  immune system.  International market introduction of these  tests
began in the third quarter of 1994.
      
      The  Company  launched two autoimmune products in  the  international
market  during the second quarter of 1995, a quantitative thyroid  receptor
autoantibodies  assay, which is used for the diagnosis of  Grave's  disease
and  the  complement activation enzyme assay ("CAE") which provides general
information about the immune system in disease states such as rheumatic and
rare  connective  tissue disorders as well as tissue injury.   The  Company
received  510(k) clearance from the FDA in the fourth quarter of  1995  for
its CAE kit.
      
      During  the third quarter of 1995 the Company launched worldwide  its
second  generation  Parathyroid Hormone-related  Protein  ("PTHrP")  assay.
PTHrP  is  the agent responsible for the condition of humoral hypercalcemia
of  malignancy.  This is a condition in which serum calcium is increased to
potentially life threatening levels.  This assay provides customers with  a
superior  product  that has significantly improved sensitivity  and  better
definition  of  the protein under investigation than the  first  generation
product.   This  product  is being distributed as  a  "research  use  only"
product  in  the  US  and  is  targeted to the  clinical  research  market.
Internationally,  the Company is pursuing registration in several  European
countries as well as Japan.
      
      During  the  third  quarter  of  1995,  the  Company  experienced  an
increase  in  demand for one of its hepatitis assays due to a  competitor's
kit  becoming  unavailable  to the market.  This  opportunity  resulted  in
approximately $2.9 million in sales during 1995.  The competitor re-entered
the marketplace during the first quarter of 1996.  Sales of this assay were
approximately $2.2 million during 1996.  While a portion of these sales has
been maintained since the competitor re-entered the market,  the impact  on
future sales is uncertain at this time.
      
      During  the fourth quarter of 1995 the Company received the  approved
licensure  from the FDA for the final two assays within the Hepatitis  line
which  gave  the  Company a complete panel of seven  EIA  approved/licensed
assays used in the diagnosis of hepatitis A and B infections.
      

MARKETING
      
       The  Company's  medical products are sold to commercial  and  public
health  laboratories, blood banks, research and teaching  institutions  and
hospital  laboratories,  which  use the Company's  kits  to  conduct  tests
ordered  by  physicians. Increased frequency of use of the  Company's  kits
will  depend, in part, upon the acceptance by practicing physicians of  the
need  and  desirability  for measuring certain therapeutic  drug,  hormone,
peptide  and  serology  levels  in  the evaluation  of  diseases  and  body
disorders.
      
            In North America, the Company's principal market for its medical
products  includes approximately 1,200 clinical reference laboratories  and
2,500  hospitals,  which  have laboratories that  perform  immunodiagnostic
testing.  In  the United States and Canada, the Company utilizes  a  direct
sales force, combined with selected independent distributors, to market its
products.
      
       The Company also utilizes foreign distributors in conjunction with a
subsidiary in the United Kingdom to market its products abroad.  Since 1989
Sorin has been the distributor for many of the Company's products in Italy,
Spain,  Portugal, Germany and the Benelux countries.  As part of  the  1990
acquisition  from Baxter, the Company manufactures and sells to  Sorin  the
Clinical  Assays products for distribution in the above mentioned countries
and  France. Pursuant to these arrangements, the Company recorded sales  to
Sorin  of  $7,965,000 for the year ended December 31, 1996, which comprised
18%  of  total  sales. Other transactions entered into with Sorin  and  its
subsidiaries  are  set  forth  in  Note 6  of  the  Company's  consolidated
financial  statements  contained elsewhere herein. Other  than  Sorin,  the
Company  is not dependent on any single customer for more than 15%  of  its
business.

       The  Company's international sales constitute 50% of sales  for  the
year ended December 31, 1996; 48% of sales for the year ended December  31,
1995 and 50% of sales for the year ended December 31, 1994.

       Because  of  the  limited  shelf life of the  Company's  radioactive
tracer, the Company delivers products by international air freight  to  its
foreign markets.
RESEARCH AND PRODUCT DEVELOPMENT

       The ability of the Company to compete effectively in the marketplace
will  depend  upon the success of its efforts to improve existing  products
and  to  develop  new  products, primarily non-isotopic  and  conducive  to
instrumentation,  that  are useful to the medical diagnostic  and  research
markets. The levels of research and development expenditures by the Company
during the periods shown below were as follows:
      
                                                       Percent of
                                         Amount        Net Sales

     Year ended December 31, 1996    $4,163,000           9.4%
     Year ended December 31, 1995    $3,748,000           8.2%
     Year ended December 31, 1994    $5,069,000          11.9%

        The  reduction in research spending in 1995 from the level in 1994,
resulted  primarily  from  the  discontinuance  of  a  development  program
discussed in Note 2 of the financial statements contained elsewhere herein.
      The  Company  has  established scientific  advisory  panels  for  its
autoimmune and bone and mineral metabolism product lines.  In addition, the
Company  intends  to establish a third scientific panel in  its  infectious
disease segment.  These panels are overseen by a scientific advisory board.
Prior to his death in March 1997, the scientific advisory board was led  by
Dr.  Pierre  M. Galletti, the Company's Chairman of the Board.   Also,  Dr.
Michael  Steffes, a director of the Company, is a member of the  Scientific
Advisory Board.
      
MANUFACTURING

       The  Company  manufactures its immunoassay kits  and  serum  protein
products   in  two  locations  within  the  United  States.   It  maintains
manufacturing  and administration activities in its principal  facility  in
Stillwater,   Minnesota,   which   consists   of   120,000   square   feet.
Additionally,  the Company is vertically integrated into the production  of
bulk antisera and maintains a USDA licensed animal facility on 116 acres in
Windham,  Maine  (the  Serum Proteins segment of the  Company's  business).
Management  believes  that it will have adequate  capability  to  meet  its
anticipated  manufacturing  needs in all  current  product  lines  for  the
foreseeable future.

       The  steps  involved in manufacturing the Company's immunoassay  and
serum  protein kits include the following:  i) the isolation and production
of  antigens;  ii) the development and production of antibodies;  iii)  the
design  and  development of the required reagent system; iv) the iodination
or  conjugation  of  precursors; v) the manufacture and  packaging  of  the
components in the kit format; and vi) ongoing quality control to  meet  all
regulatory requirements.

       As  a  result of strategic alliances and acquisitions over the  past
several  years, the Company has an extensive line of immunoassay and  serum
protein  assays  that  are manufactured in a cost  effective  manner  in  a
quality  environment.   The Company's products  and  kits  consist  of  the
components   necessary  to  perform  specific  assays  in  consistent   and
reproducible  fashion.  Antisera are a critical component in  the  products
which  are  manufactured using RIA, ITA, EIA and IFA technologies  and  the
Company  insures the quality of this raw material from its  source  in  its
Serum  Protein  segment of the business.  In addition to these  antiserums,
the  components  of  the  immunoassay  kits  include  specialized  chemical
reagents,  reference  standards and performance data required  to  properly
calibrate test results.  Raw materials used in these components meet design
specifications.   The  Company is not dependent on any particular  supplier
for  ongoing operations.  Some raw materials critical in the production  of
the  Company's  products have extensive lead times  for  supply.   Lack  of
supply of critical raw materials would have a materially adverse affect  on
the  Company.  For this reason the Company continually strives to  maintain
multiple sources for its most critical raw materials.


      The Company maintains quality controls for the assurance of accurate
and reliable test kits and to meet FDA good manufacturing practices
("GMP"). The Company also complies with procedures mandated by the Nuclear
Regulatory Commission (NRC) for the use and disposal of radioactive
materials.

COMPETITION

      Historically  the Company has developed and marketed  diagnostic  and
research products serving specialized markets not adequately served by  its
largest  competitors.  Included here are the fields of endocrinology,  bone
and  mineral  metabolism and therapeutic drug monitoring.   However,  as  a
result  of  the  Company's acquisition of the Clinical Assay product  lines
from  Baxter and relationship with Sorin, the Company now competes  with  a
number  of the larger immunodiagnostic companies offering similar lines  of
RIA and EIA products.
      
      The  Company's major competition, outside the specialty product area,
includes  Abbott  Diagnostics, Diagnostic Products Corporation,  Hybritech,
Ares-Serono,  and  CIBA  Corning  Diagnostic  Corporation.   The  principle
elements  of competition for the Company are based upon providing  quality,
consistent and reliable products and services.  Price is only a factor  for
those  tests in the larger, more competitive markets.  The Company  intends
to  maintain its competitive differentiation in the market by selecting new
and  innovative  technology approaches to both the  routine  and  specialty
market analytes.  Also, the Company intends to develop and maintain quality
customer relationships with health care professionals.
      
GOVERNMENT REGULATION

       Under the Medical Device Amendments of 1976, the Company is required
to  file  an  annual  registration statement with the FDA  and  to  provide
updated  device listings.  The Company is also required to  submit  a  pre-
market  notification submission to the FDA for each new diagnostic product.
This  submission may be either a 510(k), a premarket approval  application,
or  a  product license application, unless the product is being distributed
for  research or investigational use only. The FDA also imposes rules  with
respect  to  GMP.   The  Company believes it  is  in  compliance  with  FDA
regulations.    The   Company  also  complies   with   foreign   government
regulations, specifically for Japan, France, Germany, Canada,  England  and
other  countries where required.  These requirements include  adherence  to
GMP,  device  listings, premarket notifications, or product licenses  where
applicable.  Additionally, the Company is in the process of certifying  its
Quality  Assurance system to ISO 9000 standards and hopes to  complete  the
registration process under this standard by the end of 1997.

       Because the Company uses radioactive isotopes in the manufacture  of
some  of its products, it is required to maintain licenses authorizing  the
possession,  use  and distribution of radioactive material.   The  licenses
were  renewed in 1993 and will expire by their terms in 1998.  To  maintain
the  licenses,  the  Company is required to keep  certain  records  and  to
demonstrate continued compliance with NRC regulations and the conditions of
its  radioactive licenses.  Although not expected, loss of  these  licenses
would have a materially adverse affect on the Company.

       The Company believes it is in compliance with all federal, state and
local regulations regarding the discharge of material into the environment.
Additionally,  the  cost  to maintain licenses and meet  environmental  and
safety requirements is not material to the Company's consolidated financial
statements  and  the  Company  does  not  expect  any  material   financial
commitment in the near-term.
      
      
FOREIGN AND DOMESTIC OPERATIONS AND INTERNATIONAL SALES

       Company  information with respect to foreign and domestic operations
and  international  sales  is  set  forth  in  Note  12  to  the  Company's
consolidated financial statements contained elsewhere herein.
      
PATENTS

       The  Company  has been issued patents covering (i)  the  method  and
radioactive  tracers  used  for the immunoassay of  C-terminal  parathyroid
hormone,  (ii)  bioassay  for  parathyroid  hormone,  and  (iii)  usage  of
iodinated  or fluorescent forms of cyclosporin in immunoassay kits.   These
patents  expire  on  July 26, 1999; January 17, 2000; and  April  1,  2002,
respectively.

       The  Company  does  not believe that patent  protection  will  be  a
material  factor  for  its current product line offering,  because  of  the
Company's proprietary know-how regarding the production and development  of
its   product   lines.   Going  forward,  the  Company  has  filed   patent
applications  for several new product development programs,  and  has  also
negotiated  exclusive  licenses  to patent applications  filed  by  outside
product  development collaborators.  Certain other companies may have  been
issued  or  applied  for  patents with respect to  products  or  technology
manufactured  by, or of interest to the Company.  Management is  unable  at
this  time to determine the impact, if any, which any such patents may have
on the Company.

LICENSES AND TRADEMARKS

       The  Company  holds  certain licenses for  technology,  intellectual
property   and  distribution  rights.   The  Company  also  holds   certain
registered  trademarks  such  as CYCLO-Trac  registered  trademark,  N-tact
registered  trademark and PTH-MM registered trademark as  well  as  several
other   non-registered  trademarks.   The  terms  of  these  licenses   and
trademarks  vary.  The Company does not believe that any of these  licenses
or trademarks is material to its business or operations.

      As of December 31, 1996 the Company had 282 employees, including part-
time employees.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
      
RESULTS OF OPERATIONS
      Sales   in   1996  were  $44,304,000,  a  3  percent  decrease   from
$45,760,000  in 1995.  1995 and 1996 results included sales from  a  single
test that resulted from a competitor's product becoming unavailable to  the
market  from  June  1995  until  March  1996.   In  the  absence  of   this
development,  1995  and  1996 total sales would  have  remained  relatively
unchanged.   1995  sales  were 8 percent above 1994 sales  of  $42,503,000.
This  increase  was  due  primarily to sales from the  Company's  hepatitis
assays,  as  previously discussed, combined with sales  from  new  products
introduced  during  1995  and the latter part  of  1994  in  the  Company's
autoimmune  disease,  bone and mineral metabolism  and  infectious  disease
market segments.  Increased sales were partially offset by declines in  the
Company's  oncology and endocrinology market segments due to the  continued
shift  in  the  diagnostic industry from isotopic, manual testing  to  non-
isotopic, automated and semi-automated testing.
      
      Domestic  sales  decreased 8% from $23,832,000 to   $22,017,000.   As
discussed above, through February 1996, the Company experienced an increase
in  demand  for  one  of  its hepatitis assays due to  a  competitor's  kit
becoming unavailable to the market in June 1995.  Since the competitor's re-
entry  during  the  first quarter of 1996, the Company  has  experienced  a
decline of these product sales from their levels during the second half  of
1995.   This  opportunity resulted in approximately $2.2 million  and  $2.9
million  in sales during 1996 and 1995, respectively. In addition, domestic
sales have continued to be negatively impacted by declines in the Company's
oncology  and endocrinology market segments, as discussed above.  Partially
offsetting  these  declines  were continued  increases  in  the  autoimmune
disease  market  segment, increases in the Company's serum  protein  market
segment and increases in the Company's Vitamin D assays, which are part  of
the  bone and mineral metabolism market segment.  1995 sales increased  12%
from  $21,282,000 in 1994 due primarily to the increase in sales  from  the
hepatitis  assay described above, as well as increases in the  autoimmunity
segment  offset  with  declines in the endocrinology  and  oncology  market
segments.
      
      1996  international sales increased 2% to $22,287,000  compared  with
1995  sales  of  $21,928,000.  1995 sales increased 3% from 1994  sales  of
$21,221,000.  Sales were favorably impacted in 1996 and 1995 due  primarily
to the introduction of second generation Epstein Barr Virus diagnostic kits
during  1995.   Sales were negatively impacted in both  years  due  to  the
continued   declines  in  the  routine  endocrinology  and  transplantation
segments.
      
      Gross  margins  were  51 percent of sales in 1996  compared  with  49
percent  of  sales  in  1995 and 46 percent in 1994. The  decline  in  1994
margins  is  attributable to the $750,000 charge for excess inventories  as
discussed  in  Note  2  of the Company's consolidated financial  statements
contained  elsewhere herein. Exclusive of the inventory write  down,  gross
margins  were  48  percent of sales in 1994. Gross  margins  have  improved
during  the  last  two  years  due  to improved  product  mix  as  well  as
efficiencies  derived  from an operational restructuring.   Notwithstanding
this improvement, the Company's margins continue to be highly sensitive  to
product mix and volume changes.
      
      The  Company's ratio of selling, general and administrative  expenses
to sales was 30 percent in 1996, 28 percent in 1995 and 30 percent in 1994.
These expenses, as a percentage of sales, are expected to remain relatively
consistent with 1996.
      
      Research  and development expenses were $4,163,000 in 1996,  compared
with  $3,748,000 in 1995 and $5,069,000 in 1994. The increase  in  1996  is
primarily  due to increased emphasis on new product development,  including
the   establishment  of  scientific  advisory  panels  for  the   Company's
autoimmune  and  bone and mineral metabolism segments.   These  panels  are
intended  to  strengthen the Company's ties with the scientific  community.
The decrease in 1995 spending compared with 1994 levels is attributable  to
the discontinuance during 1994 of the Fluorescence Polarization Immunoassay
("FPIA")  development  project as discussed in  Note  2  of  the  Company's
consolidated financial statements contained elsewhere herein.  Exclusive of
FPIA,  these expenses represent 9 percent, 8 percent and 9 percent of sales
in  1996,  1995 and 1994, respectively.  Research and development  expenses
are  projected to increase slightly due to the Company's increased emphasis
on new development activities and increased scientific panel activity.
      
      Interest  income  net of expense was $96,000 in  1996  compared  with
interest  expense of $348,000 in 1995 and $365,000 in 1994.   The  interest
income  was  attributable to the elimination of all long term  debt  during
1995  and  higher  average cash balances in 1996.   1995  expense  includes
interest on certain tax obligations.
      
      Income  tax  expense  was  24  percent  of  income  before  taxes  or
$1,299,000, compared with 27 percent or $1,571,000 in 1995 and $193,000  in
1994.   The decline in the effective tax rate is due to the recognition  of
certain  deferred tax assets during 1996.  The tax expense in 1994  related
primarily to book reserves and liabilities not deductible for tax  purposes
until paid.  The effective rate is expected to remain relatively consistent
with 1996.
      
      Net  income  in 1996 was $4,112,000, or 25 cents per share,  compared
with  a  net income of $4,263,000, or 26 cents per share, in 1995  and  net
loss of $4,505,000, or 28 cents per share, in 1994.   The 1994 loss results
from  $6.5  million  in charges, as discussed in Note 2  to  the  Company's
consolidated financial statements contained elsewhere herein.

LIQUIDITY AND CAPITAL RESOURCES
      
      INCSTAR's  free  cash  flow  (operating  cash  flow  less  investment
activities)  was  $905,000  in 1996, compared to  $5,190,000  in  1995  and
$3,118,000  in  1994.  This decrease is attributable to  increased  capital
spending  associated with instrumentation, manufacturing  improvements  and
computer  upgrades  as  well as spending associated with  the  purchase  of
intellectual  property and purchased technology.  The  Company's  ratio  of
total debt to total capital was 16 percent in 1994.
      
      Working  capital  increased to $19,189,000  at  year-end  1996,  from
$14,947,000  at the end of 1995, resulting from increased cash  levels  and
higher  inventory balances combined with lower accrued compensation due  to
timing of payroll disbursements.
      
      Capital   expenditures  for  1996  were  $2,645,000,  compared   with
$1,557,000  in  1995 and $923,000 in 1994.  For 1997, capital  expenditures
are  expected  to  be  approximately $3.8  million,  primarily  for  a  new
enterprise   resource  planning  system,  manufacturing  improvements   and
instrumentation.
      
      The   Company's  primary  sources  of  liquidity  are  a  $1  million
revolving  bank  credit line secured by Company assets and a  $4.0  million
unsecured  credit line with Fiat Finance N.A., Inc. (Fiat).   At  year-end,
the  Company had no outstanding borrowings under these credit  lines.   The
Company anticipates that the generation of free cash flow and the resources
available  within  the  Fiat  Group  will  provide  sufficient  sources  of
liquidity for  planned capital and research and development expenditures.

respective  beneficiaries upon the later of (1) an individual's  retirement
from the Company after attainment of 60 years of age, (2) his attainment of
60 years of age following termination of employment or (3) his death during
the term of employment (each one a "triggering event").  Subject to vesting
requirements (the annual benefit amounts vest at the rate of 10%  per  year
of  employment), the retirement agreement provides for the payment  to  the
individuals  or their beneficiaries of annual benefits for a period  of  15
years  following the occurrence of a triggering event.  The amount  of  the
benefit  is adjusted annual to reflect changes in the cost of living.   The
annual benefit amount at December 31, 1996 for Mr. Booth was $62,800.

        The Company maintains an executive income continuation plan for the
benefit  of  Dr.  Majewski, Mr. Wellock and Mr. Maun.   The  plan  provides
payments  for  15 years to such officers or their respective  beneficiaries
upon  the  later  of  (1) an officer's retirement from  the  Company  after
attainment  of  60  years of age, (2) his attainment of  60  years  of  age
following  termination of employment or (3) his death during  the  term  of
employment.   The  annual retirement payment is the product  of  an  annual
benefit  rate  set by the Board of Directors ( in 1996) multiplied  by  the
number of years of employment, up to a maximum of 15 years, and as adjusted
to  reflect cost of living changes during the payment period.  An officer's
rights under the plan are fully vested after 10 years of employment.  As of
December 31, 1996, the estimated annual retirement payment amounts were  as
follows:  Dr. Majewski, $13,800; Mr. Wellock, $28,300 and Mr. Maun, $7,500.

                NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                     
NOTE 1_SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS
      INCSTAR  Corporation  (the "Company") is a medical  immunodiagnostics
company  focused on the development, production and worldwide marketing  of
reagents,   particularly   for   bone/mineral  metabolism,   endocrinology,
infectious  and  autoimmune  diseases.  The Company  predominantly  markets
these products in North America, Europe and Asia.

       Since  December 1989, the Company has been majority-owned by  BioFin
Holding  International  B.V.  ("BFHI"), a  subsidiary  of  Sorin  Biomedica
Diagnostics S.p.A. ("Sorin") which is an Italian affiliate of Fiat, Inc.

PRINCIPLES OF CONSOLIDATION
      The   accompanying  consolidated  financial  statements  include  the
accounts   of  INCSTAR  Corporation   and  its  wholly-owned  subsidiaries,
Atlantic Antibodies, Inc., INCSTAR Ltd. and Immuno Nuclear Export Ltd.  All
material  inter-company accounts and transactions have been  eliminated  in
consolidation.   Certain  amounts  for periods  prior  to  the  year  ended
December  31,  1996  have  been reclassified to conform  with  the  current
classifications.
      
CASH EQUIVALENTS
       Cash  equivalents consist primarily of investments in  money  market
accounts with current maturities.

RESTRICTED CASH
        Through  December 31, 1995 the Company maintained  a  self  insured
workers  compensation insurance plan.  Pursuant to the  plan,  the  Company
holds  a  certificate of deposit with current maturity  as  a  compensating
balance  with  a bank.  These funds are restricted to assure future  credit
availability  for  the potential self insured aggregate  limits  under  the
plan.   The funds are required to be on deposit with a bank under Minnesota
state regulations and are expected to be released in the fourth quarter  of
1997.  As of January 1, 1996, the Company is no longer self insured.

INVENTORIES
        Inventories  are  valued  at  the  lower  of  average  cost,  which
approximates the first-in, first-out (FIFO) method, or market.

FAIR VALUE OF FINANCIAL INSTRUMENTS
        All  financial instruments are carried at amounts that  approximate
estimated fair value.

PROPERTY AND EQUIPMENT
       Property and equipment, including equipment under capital leases, is
reported   at   cost   less  accumulated  depreciation  and   amortization.
Maintenance  and  repairs are charged to expense as incurred.  The  Company
computes depreciation and amortization using the straight-line method based
on  estimated  useful  lives  of three to seven  years  for  equipment  and
furniture and seven to thirty years for buildings and improvements.

INTANGIBLE ASSETS
      Intangible assets includes patents, trademarks, intellectual property
and purchased technology, goodwill and product distribution rights. Patents
and  trademarks are amortized using the straight-line method over  a  five-
year  period.  Goodwill, which represents the cost in excess  of  the  fair
value  of net assets acquired, is amortized using the straight-line  method
over  a ten-year period. Intellectual property and purchased technology  is
amortized  using  the  straight line method over the  properties  estimated
useful  lives  which  range from seven to ten years.  Product  distribution
rights  are amortized using the straight line method over the life  of  the
agreement  or  the  estimated  product life,  whichever  is  shorter.   The
carrying  value of intangible assets is regularly reviewed by the  Company,
and  a  loss  is recognized when the net realizable value falls  below  the
unamortized cost.

RESEARCH and Development
     Research and development costs are expensed when incurred.

INCOME TAXES
      The Company accounts for income taxes in accordance with Statement of
Financial  Accounting  Standard ("SFAS") No.  109.   Under  the  asset  and
liability  method of SFAS No. 109, deferred tax assets and liabilities  are
recognized  for  the  future tax consequences attributable  to  differences
between  the  financial statement carrying amounts of existing  assets  and
liabilities  and  their  respective tax bases.   Deferred  tax  assets  and
liabilities  are  measured using enacted tax rates  expected  to  apply  to
taxable  income  in  the  years in which those  temporary  differences  are
expected  to  be recovered or settled.  Under SFAS No. 109, the  effect  on
deferred  tax assets and liabilities of a change in tax rates is recognized
in income in the period that includes the enactment date.

INCOME (LOSS) PER SHARE
      Income (loss) per share is computed by dividing net income (loss)  by
the  weighted  average number of shares of common stock  and  common  stock
equivalents,  consisting of stock options and warrants, outstanding  during
the period.  For all periods presented, fully diluted and primary income or
loss  per  share are the same.  For 1994, the effects of stock options  and
warrants  were  excluded  from the computation of weighted  average  shares
outstanding because their effects were antidilutive.
     
FOREIGN CURRENCY TRANSLATION
      Assets and liabilities of foreign operations are translated at  rates
of  exchange  in effect at period end. Statement of operations amounts  are
translated at the average rate of exchange for the period. Gains and losses
resulting  from  translation are accumulated in  a  separate  component  of
shareholders' equity. Foreign currency transaction gains and losses,  which
are   not  material,  are  included  in  the  consolidated  statements   of
operations.

STOCK BASED COMPENSATION
      The  Company applies Accounting Principles Board Opinion No. 25  (APB
No.   25),   ACCOUNTING  FOR  STOCK  ISSUED  TO  EMPLOYEES,   and   related
interpretations in accounting for its plans.  Accordingly, no  compensation
expense  has been recognized for its stock-based compensation  plans.   The
Company  has  adopted  the  disclosure requirements  under  SFAS  No.  123,
Accounting and Disclosure of Stock-Based Compensation.

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  the  date  of  the
financial  statements  and the reported amounts of  revenues  and  expenses
during  the  reporting  period.  Actual results  could  differ  from  those
estimates.

NOTE 2_ UNUSUAL ITEMS AND INVENTORY VALUATION ADJUSTMENTS

    In December, 1994 the Company recorded a $750,000 charge related to the
write down of excess inventories and a $2,450,000 unusual charge related to
the termination of certain distribution and supply agreements ($540,000) as
well  as  severance  and other costs related to senior  management  changes
($1,910,000).   The  amount  remaining to be paid  at  December  31,  1996,
exclusive  of amounts included in noncurrent liabilities (Note 9, Executive
Retirement Plans) is $10,000, which is included in accrued expenses in  the
accompanying consolidated balance sheet.

     In  May,  1994  the  Company discontinued the development  of  certain
purchased  technology  acquired in 1992 from Robert  Dowben  Associates,  a
diagnostic  research  company, and incurred a one-time  pre-tax  charge  of
$3,300,000.   The  majority of this charge related  to  the  write  off  of
tangible  and  intangible assets ($1,560,000), costs incurred to  terminate
contracts  with  outside  vendors and consultants ($797,000),  as  well  as
severance and related costs for terminated employees ($943,000).   None  of
these amounts remain to be paid on December 31, 1996.

      The Company has a revolving line of credit from a bank which provides
for  maximum borrowings of $1,000,000 through January 31, 1997, is  secured
by  accounts  receivable,  and has an interest  rate  based  on  the  prime
interest  rate  or  LIBOR  plus  2.50%.  In addition,  the  Company  has  a
$4,000,000  revolving  line of credit with Fiat Finance  N.A.,  Inc.  which
expires on October 1, 1997.

       At  December  31,  1996  and 1995, property and  equipment  includes
capital lease costs of $288,000 and $842,000, respectively, and accumulated
amortization  of  $288,000 and $773,000, respectively.  Lease  amortization
included  in depreciation was $40,000 for the year ended December 31,  1996
and $158,000 for the year ended December 31, 1995.

       The  Company  leases certain manufacturing and  other  equipment  in
connection with its normal operations.  Rent expense under these  operating
leases was $226,000, $295,000 and $238,000 for the years ended December 31,
1996,  1995 and 1994, respectively.  Future minimum lease payments for  all
noncancelable  operating leases having a remaining term in  excess  of  one
year   are   as   follows:   1997_$173,000;  1998_$116,000;   1999_$44,000;
2000_$5,000.

       The  Company  is  obligated to make royalty payments  under  several
distribution  and  licensing agreements.  The majority of these  agreements
call  for  payments based on  a percentage of sales and contain no  minimum
royalty  clause.  Royalty expense under these agreements was $1,563,000  in
1996, $1,715,000 in 1995 and $1,099,000 in 1994.

      The provision for income taxes differs from the statutory federal tax
rate of 34% applied to income (loss) before income taxes as follows:

      The tax effects of temporary differences that give rise to significant 
portions of the deferred tax assets and liabilities at December 31, 1996 and 
1995 are as follows:

                                              December 31,     December 31,

Total net deferred tax asset (liability)     $     540,000   $     ( 15,000)

       The  valuation allowance for deferred tax assets as of December  31,
1996  and 1995 was $1,639,000 and $2,553,000, respectively.  The net change
in  the  valuation allowance for the year ended December  31,  1996  was  a
decrease  of  $914,000.   In assessing the realizability  of  deferred  tax
assets,  management considers whether it is more likely than not that  some
portion  or  all  of  the deferred tax assets will not  be  realized.   The
ultimate  realization  of  deferred  tax  assets  is  dependent  upon   the
generation  of  future  taxable income during the periods  in  which  those
temporary   differences  become  deductible.   Management   considers   its
projected future taxable income and tax planning strategies in making  this
assessment.

NOTE 8_EMPLOYEE SAVINGS RETIREMENT AND VALUE SHARING PLAN

     The  Company adopted a Salary Savings Plan under Section 401(k) of the
Internal  Revenue Code, effective November 1, 1985. Participants make  pre-
tax contributions of up to 15% of their wages subject to an annual limit of
$9,500.  The  Company  is  required to match 50% of  that  portion  of  the
participant's  pre-tax  contribution  which  does  not  exceed  6%  of  the
participant's compensation. The Company contributed $270,000 for  the  year
ended December 31, 1996, $262,000 for the year ended December 31, 1995, and
$273,000 for the year ended December 31, 1994.
     
     In  1994  the  Company  changed its profit  sharing  plan  to  a  non-
contributory  value sharing plan.  Cash payments to all eligible  employees
are  based  on  the  improvement in economic value as well  as  a  targeted
performance  factor  for  economic value added.  The  Company  incurred  $0
expense for the year ended December 31, 1996, $984,000 expense for the year
ended December 31, 1995 and $0 for the year ended December 31, 1994.
     

NOTE 9_EXECUTIVE RETIREMENT PLANS

      The   Company  has  individual  retirement  agreements  with  certain
current  and  prior  executive  officers  which  are  intended  to  provide
continued   compensation   to   such  individuals   or   their   respective
beneficiaries  upon the later of their retirement from  the  Company  after
attainment  of  sixty years of age (fifty-five years of age  for  one  plan
participant) or attainment of sixty years of age (fifty-five years  of  age
for  one  plan  participant) following termination of employment,  or  upon
death during the term of employment (the "triggering events").  Subject  to
vesting requirements, the retirement agreements provide for the payment  to
these individuals or their respective beneficiaries, of annual benefits for
a  period of fifteen years following the occurrence of a triggering  event.
The  amount  of annual benefits is adjusted annually to reflect changes  in
the cost of living.  The annual benefit amounts vest at the rate of 10% per
year.

      The  Company maintains an executive income continuation plan for  the
benefit  of  executive officers not covered under the agreements  discussed
above.   The  plan provides payments for fifteen years to such officers  or
their  respective  beneficiaries upon the later of an officer's  retirement
from  the  Company after attainment of sixty years of age or attainment  of
sixty  years  of  age following termination of employment,  or  upon  death
during  the  term  of  employment.  The annual retirement  payment  is  the
product of an annual benefit rate set by the Board of Directors ($3,333 for
1996)  multiplied by the number of years of employment, up to a maximum  of
fifteen years, and as adjusted to reflect the cost of living changes during
the  payment  period.  An officer's rights under the plan are fully  vested
after ten years of employment or upon change in the controlling interest of
the Company.

      In  connection  with  both  of the above  plans,  included  in  other
noncurrent  liabilities  at December 31, 1996 and 1995  is  $3,285,000  and
$3,136,000,  respectively, representing the present  value  of  the  future
liability.   Also, included in accrued expenses at December  31,  1996  and
December  31, 1995 is $145,000 and $31,000, respectively, representing  the
current  portion  of  this liability.  The Company  intends  to  fund  this
obligation  through life insurance contracts on the individual  executives.
Included  in  Other assets at December 31, 1996 and 1995 is $1,020,000  and
$934,000,  respectively, of cash surrender value in connection  with  these
policies.


NOTE 10_EMPLOYEE STOCK PURCHASE AND OPTION PLAN

        Under the Company's stock option plans, officers, directors,
consultants and key employees may be granted options to purchase the
Company's common stock at no less than 100% of the market price on the date
the option is granted.  Options generally become exercisable over two to
four years and have terms of five or ten years.

Option  activity  in the Company's various option plans  is  summarized  as

Balance December 31, 1996         445,168     669,640   $      3.81

      As  of  December 31, 1996 options for 538,140 shares were exercisable
at prices ranging from $1.44 to $8.25 per share.
      
      At  December  31,  1996, the range of exercise prices  and  weighted-
average  remaining contractual life of outstanding options was  $1.44-$8.25
and 6.12 years, respectively.
      
       The  Company  also had an Employee Stock Purchase Plan.   This  plan
enabled  eligible employees to purchase the Company's Common Stock  at  the
lower of 85% of the fair market value on the first or the last day of  each
plan  year.  The  number of shares reserved for sale under  this  plan  was
300,000,  of which all shares have been sold.  The Company does not  intend
to issue more shares under this plan.

       In  October  1995, the Financial Accounting Standards  Board  issued
Statement of Financial Accounting Standards No. 123, "Accounting for Stock-
Based   Compensation."   The  Company  has  adopted   the   disclosure-only
provisions.   Had compensation cost for the Company's stock  option  grants
and  employee stock purchase plan been determined consistent with SFAS 123,
the Company's net income and earnings per share would have been changed  to
the pro forma amounts indicated below:

                                          1996               1995
Net income (in 000s)  As reported       $  4,112        $    4,263
                      Pro forma            4,032             4,209

Earnings per share    As reported       $   0.25        $     0.26
                      Pro forma             0.24              0.26

        The effects of applying SFAS No. 123 in this pro forma disclosure
are not indicative of future amounts as compensation expense applicable to
awards made prior to 1995 are not considered.

        The fair value of stock options used to compute pro forma net
income and earnings per share disclosures is the estimated present value at
grant date using a Black-Scholes option-pricing model with the following
weighted average assumptions for 1996 and 1995:  dividend yield of 0%;
expected weighted average volatility of 63.7%; a weighted average risk free
interest rate of 5.9% and an expected holding period of 9.3 years.  The
weighted average values of the options granted are $3.40 and $1.98 for 1996
and 1995, respectively.

NOTE 13_WARRANTS AND STOCK PURCHASE RIGHTS

       The  Company has issued to BFHI a warrant to purchase up to  730,720
shares of Common Stock at the prevailing market price and has granted  BFHI
the  right to purchase additional Common Stock at a price identical to  any
new  issuances.   These agreements enable BFHI to maintain  a  minimum  51%
ownership in the Company.

NOTE 14_SUBSEQUENT EVENT

         On  January 24, 1997, the Company announced that it has  signed  a
Memorandum  of  Understanding  ("the Memorandum")  with  American  Standard
Inc.("ASI"),  a  subsidiary  of  American Standard  Companies  Inc.,  which
contemplates  acquisition of the Company by a subsidiary of ASI.   Pursuant
to  the  Memorandum, each INCSTAR common share would be converted into  the
right  to  receive $6.32 in cash, and INCSTAR  would become a  wholly-owned
subsidiary of ASI.  Under the merger proposal, INCSTAR would become part of
a newly formed Medical Systems Group within ASI.

         The  Memorandum of Understanding has been approved  by  a  Special
Committee  of independent INCSTAR directors and the boards of directors  of
INCSTAR and ASI.

         The  proposed  merger is subject to negotiation and  execution  of
mutually  satisfactory  definitive documentation, receipt  by  the  Special
Committee  and  the  board of directors of INCSTAR of a  fairness  opinion,
approval  of  the definitive merger agreement by the Special Committee  and
the  boards of directors of INCSTAR and ASI, approval of the merger by  the
holders  of  a  majority of the issued and outstanding  shares  of  INCSTAR
common stock, and receipt of all required regulatory approvals and material
third party consents.

         The  Merger  Agreement further provides for  the  payment  by  the
Company  to ASI of a $2.5 million termination fee if the Company terminates
the merger as defined in the Agreement.

         The Company also announced that BFHI, the majority shareholder  of
INCSTAR  and a wholly owned subsidiary of Sorin, has informed INCSTAR  that
Sorin has entered into a Memorandum of Understanding with ASI regarding the
proposed  sale  of  Sorin's  European Diagnostics  Division  to  ASI.   The
Memorandum of Understanding between ASI and INCSTAR contemplates  that  the
simultaneous closing of the Sorin sale of its European Diagnostics Division
will be a condition to the proposed merger.

                       INDEPENDENT AUDITORS' REPORT
                                     
                                     
The Board of Directors and Shareholders of INCSTAR Corporation:

     We  have  audited  the  consolidated financial statements  of  INCSTAR
Corporation  and subsidiaries as listed in the accompanying index  in  Item
14(a)(1)  on  page  24. In connection with our audits of  the  consolidated
financial statements, we also have audited the financial statement schedule
as  listed  in  the accompanying index in Item 14(a)(2) on page  24.  These
consolidated financial statements and financial statement schedule are  the
responsibility  of  the  Company's management.  Our  responsibility  is  to
express an opinion on these consolidated financial statements and financial
statement schedule 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 financial position  of
INCSTAR Corporation and subsidiaries as of December 31, 1996 and 1995,  and
the  results of their operations and their cash flows for each of the years
in  the  three-year  period  ended December 31, 1996,  in  conformity  with
generally accepted accounting principles. Also in our opinion, the  related
financial  statement  schedule, when considered in relation  to  the  basic
consolidated financial statements taken as a whole, presents fairly, in all
material aspects, the information set forth therein.

                   FOURTH AMENDMENT TO CREDIT AGREEMENT
                                     
                                     
THIS  FOURTH AMENDMENT is made as of the 31st day of January, 1997, and  is
by  and  between  INCSTAR  Corporation (the "Borrower")  and  Norwest  Bank
Minnesota,   National   Association,   a   national   banking   association
("Norwest").

REFERENCE  IS  HEREBY  MADE to that certain credit agreement  dated  as  of
December 27, 1993 and amended January 3, 1995 and amended February 15, 1995
and  amended  January 29, 1996 (the "Credit Agreement")  made  between  the
Borrower and Norwest.  Capitalized terms not otherwise defined herein shall
have the respective meanings ascribed to them in the Credit Agreement.

WHEREAS,  the Borrower has requested Norwest to extend the Line to February
28, 1998; and

WHEREAS, the Borrower has requested Norwest to amend Section 7.3(l) of  the
Credit Agreement; and

WHEREAS,  the  Borrower has requested Norwest amend Section 8.1(h)  of  the
Credit Agreement; and

WHEREAS, Norwest is willing to grant the Borrower's request, subject to the
provisions of this Fourth Amendment;

NOW,  THEREFORE,  in consideration of the premises and for  other  valuable
consideration received, it is agreed as follows:

1.   Section 1.2 of the Credit Agreement is hereby amended by changing  the
     said  Section  so  that,  when read in its entirety,  it  provides  as
     follows:

          Line  Availability Period.  The Line Availability Period
          will mean the period from the Effective Date to February 28, 1998
          (the "Line Expiration Date").

2.   Section 7.3(l) is added to the Credit Agreement so that, when read  in
     its entirety, it provides as follows:

          Management Change.  Refrain from permitting or suffering
          any substantial change in Borrower's management team in place  as
          of the date of this Fourth Amendment.

3.        Section  8.1(h) is added to the Credit Agreement  so  that,  when
          read in its entirety, it provides as follows:

          A  material change of control shall occur.   A  material
          change of control shall be deemed to have occurred if a change in
          ownership  of stock having the power to elect a majority  of  the
          Borrower's Board of Directors has occurred.

4.   Simultaneously  with  the  execution  of  this  Fourth  Amendment  the
     Borrower  shall execute and deliver to Norwest a Fourth  Amendment  to
     Note  (the "Fourth Amendment to Note"), duly executed by the  Borrower
     and in form and content acceptable to Norwest.  Pursuant to the Fourth
     Amendment to Note, the maturity date of the Note shall be extended  to
     February  28,  1998.  All references in the Credit Agreement  to  "the
     Note"  shall be deemed to mean the Note as modified by the First  Note
     Amendment  and the Second Note Amendment and the Third Note  Amendment
     and the Fourth Note Amendment.

5.      The Borrower hereby represents and warrants to Norwest as follows:

          A.       As of the date of this Fourth Amendment, the outstanding
          principal  balance  of  the Note is $0, and  accrued  but  unpaid
          interest thereon equals $0.
          B.      The Credit Agreement and the Note constitute valid, legal
          and  binding obligations owed by the Borrower to Norwest, subject
          to no counterclaim, defense, offset, abatement or recoupment.
          C.       The  execution, delivery and performance of this  Fourth
          Amendment  and the Fourth Amendment to Note by the  Borrower  are
          within  its corporate powers, have been duly authorized, and  are
          not  in  contravention  of  law or the terms  of  the  Borrower's
          Articles  of  Incorporation or By-laws, or of any undertaking  to
          which the Borrower is a party or by which it is bound.
          D.       All financial statements delivered to Norwest by  or  on
          behalf  of  the  Borrower,  including  any  schedules  and  notes
          pertaining  thereto,  fully  and  fairly  present  the  financial
          condition of the Borrower at the dates thereof and the results of
          operations for the periods covered thereby, and there  have  been
          no  material  adverse  changes  in  the  financial  condition  or
          business  of  the  Borrower from December 31, 1996  to  the  date
          hereof.

6.   This  Fourth  Amendment may be executed in any number of counterparts,
     each  of  which shall be deemed an original, but which taken  together
     shall  constitute one and the same instrument.  This Fourth  Amendment
     shall  not become effective until this Fourth Amendment and the Fourth
     Note Amendment have been duly executed by the Borrower and Norwest.

7.   Except  as  expressly  modified by this Fourth Amendment,  the  Credit
     Agreement  remains  unchanged and in full force and  effect.   Without
     limiting the generality of the foregoing, all advances under the  Line
     shall  continue to be evidenced by the Note, as amended by  the  First
     Note  Amendment  and  The Second Note Amendment  and  the  Third  Note
     Amendment and the Fourth Note Amendment.

IN  WITNESS  WHEREOF,  the Borrower and Norwest have executed  this  Fourth
Amendment as of the date first written above.

                       AGREEMENT AND PLAN OF MERGER


          Agreement and Plan of Merger, dated as of March 10, 1997 (this
"Agreement"), among American Standard Inc., a Delaware corporation
("Parent"), American Standard Medical Systems, Inc., a Delaware corporation
that is a wholly-owned subsidiary of Parent ("Holdings"), ISTR Merger
Corporation, a Minnesota corporation that is a wholly-owned subsidiary of
Holdings ("Mergeco"), and INCSTAR Corporation, a Minnesota corporation (the
"Company") (the Company and Mergeco being sometimes hereinafter referred to
as the "Constituent Corporations");

          Whereas, the Boards of Directors of Parent, Holdings, Mergeco and
the Company deem the merger of the Constituent Corporations advisable and
in the best interests of their respective corporations, and such Boards of
Directors have approved the merger (the "Merger") of Mergeco with and into
the Company, with the Company as the surviving corporation, upon the terms
and subject to the conditions set forth herein;

          Whereas, the respective Boards of Directors of Parent, Holdings,
Mergeco and the Company have, by resolutions, approved the execution and
delivery of this Agreement providing for the Merger;

          Whereas, the respective Boards of Directors of the Company and
Mergeco have directed that this Agreement be submitted to their respective
shareholders for approval as provided for by the Minnesota Business
Corporation Act (the "MBCA");

          Whereas, Holdings, as the sole shareholder of Mergeco, has, by
resolution, approved this Agreement and the Merger as provided for by the
MBCA; and

          Whereas, Parent, Mergeco and the Company desire to make certain
representations, warranties, covenants and agreements in connection with
this Agreement;

          Now, Therefore, in consideration of the foregoing and the
respective representations, warranties, covenants and agreements set forth
herein, and for the purpose of prescribing the terms and conditions of the
Merger, the manner and basis of converting certain shares of stock of the
Company and setting forth such other provisions as are deemed necessary and
desirable, the parties hereto agree as follows:


                                 ARTICLE I

                                THE MERGER

          1.1  THE MERGER.  Upon the terms and subject to the satisfaction
or waiver, if permissible, of the conditions set forth in ArticleVI hereof,
at the Effective Time, as defined in Section 1.5, the parties hereto shall
cause Mergeco to be merged with and into the Company, and the Company shall
be the surviving corporation in the Merger (hereinafter sometimes called
the "Surviving Corporation") and shall continue its corporate existence
under the laws of the State of Minnesota.  At the Effective Time, the
separate existence of Mergeco shall cease.

          (b)  The Merger shall have the effects set forth in Section
     302A.641 of the MBCA. Without limiting the generality of the
     foregoing, and subject thereto, the Surviving Corporation shall retain
     the name of the Company and shall possess all the rights, privileges,
     immunities, powers and franchises of Mergeco and the Company and shall
     by operation of law become liable for all the debts, obligations,
     liabilities and duties of the Company and Mergeco.

          1.2  ARTICLES OF INCORPORATION. At the Effective Time, the
Articles of Incorporation of Mergeco (in the form attached hereto as
Exhibit A) shall become the Articles of Incorporation of the Surviving
Corporation, by virtue of the Merger and this Agreement and without any
further action by the Constituent Corporations, until, subject to Section
5.9(a) hereof, thereafter amended in accordance with the provisions thereof
and as provided by law, provided that effective at the Effective Time,
Article I of such Articles of Incorporation shall be amended, by virtue of
the Merger and this Agreement and without any further action by the
Constituent Corporations, so that the name of the Surviving Corporation
shall be "INCSTAR Corporation."

          1.3  BY-LAWS.  At the Effective Time, the By-Laws of Mergeco
shall become the By-Laws of the Surviving Corporation until, subject to
Section 5.9(a) hereof, thereafter amended, altered or repealed as provided
therein and by law.

          1.4  DIRECTORS AND OFFICERS.  The directors of Mergeco and the
officers of the Company immediately prior to the Effective Time shall be
the directors and officers, respectively, of the Surviving Corporation,
each to hold office in accordance with the Articles of Incorporation and By-
Laws of the Surviving Corporation.

          1.5  EFFECTIVE TIME.  The Merger shall become effective at the
date and time when properly executed Articles of Merger (the "Articles of
Merger") relating to the Merger shall be filed with the Secretary of State
of the State of Minnesota in accordance with the MBCA or at such other
later date and time, if any, as Mergeco and the Company shall agree and as
shall be specified in the Articles of Merger.  The date and time when the
Merger shall become effective is herein referred to as the "Effective
Time."

                                ARTICLE II

                           CONVERSION OF SHARES

          2.1  COMPANY COMMON STOCK.  The manner and basis of converting
the Shares (as hereinafter defined) shall be as follows:

               At the Effective Time, each share of Common Stock, par value
$.01 per share, of the Company (a "Share" and, collectively, the "Shares")
issued and outstanding immediately prior to the Effective Time (except for
Shares then owned beneficially or of record by Parent or Mergeco or any
other subsidiary of Parent and except for Dissenting Shares (as defined in
Section 2.2)), shall, by virtue of the Merger and without any action on the
part of the holder thereof, be converted into the right to receive $6.32
(the "Merger Consideration") in cash payable to the holder thereof (pro-
rated for fractional Shares, if any), without interest thereon, upon
surrender of the certificate representing such Share.

               At the Effective Time, each Share issued and outstanding
immediately prior to the Effective Time which is then owned beneficially or
of record by Parent or Mergeco or any other subsidiary of Parent shall, by
virtue of the Merger and without any action on the part of the holder
thereof, be canceled and cease to exist, and no payment shall be made with
respect thereto.

               At the Effective Time, the holders of certificates
representing Shares shall cease to have any rights as shareholders of the
Company, except such rights, if any, as they may have pursuant to the MBCA
(including the rights of holders or beneficial owners of Dissenting Shares
pursuant to Sections 302A.471 and 302A.473 of the MBCA), and, except as
aforesaid, their sole right shall be the right to receive the Merger
Consideration for each Share represented by a certificate as aforesaid.

          2.2  DISSENTING SHARES. To the extent required by the MBCA,
Shares that are issued and outstanding immediately prior to the Effective
Time and that are held or beneficially owned by holders or beneficial
owners of such Shares who have properly exercised and preserved and
protected dissenters' rights with respect thereto in accordance with
Sections 302A.471 and 302A.473 of the MBCA ("Dissenting Shares") will not
be converted into the right to receive the Merger Consideration, and
holders or beneficial owners of such Dissenting Shares will be entitled to
receive payment of the fair value of such Dissenting Shares in cash in
accordance with the provisions of such Section 302A.473 unless and until
such holders or beneficial owners fail to perfect or effectively withdraw
or lose their rights to payment under Section 302A.473 of the MBCA.  If,
after the Effective Time, any such holder or beneficial owner fails to
perfect or effectively withdraws or loses such right, such Dissenting
Shares will thereupon be treated as if they had been converted into, at the
Effective Time, the right to receive the Merger Consideration per Share,
without interest.  The Company will give Parent prompt written notice of
any notice of intent to demand payment of the fair value of Shares under
Section 302A.473 of the MBCA received by the Company and of any withdrawal
of any such notice of intent and, prior to the Effective Time, Parent and
Mergeco will have the right to direct all negotiations and proceedings with
respect to such demands.  Prior to the Effective Time, the Company will
not, except with the prior written consent of Parent and Mergeco,
negotiate, make any payments with respect to, or settle or offer to settle,
any such demands.

          2.3  MERGECO COMMON STOCK.  The manner and basis of converting
the shares of Mergeco shall be as follows: At the Effective Time, each
share of common stock, par value $.01 per share ("Mergeco Common Stock"),
of Mergeco issued and outstanding immediately prior to the Effective Time
shall, by virtue of the Merger and without any action on the part of the
holder thereof, be converted into one fully paid and non-assessable share
of common stock, par value $.01 per share ("Surviving Corporation Common
Stock"), of the Surviving Corporation, and shall constitute the only issued
and outstanding shares of capital stock of the Surviving Corporation
immediately following the Merger.  From and after the Effective Time, each
outstanding certificate theretofore representing shares of Mergeco Common
Stock shall be deemed for all purposes to evidence ownership of and to
represent the same number of shares of Surviving Corporation Common Stock.

          2.4  EXCHANGE OF SHARES.  Prior to the Effective Time, Parent
shall deposit, or shall cause to be deposited, in trust with The Chase
Manhattan Bank or any other bank or trust company with offices in New York
or Minneapolis designated by Parent and reasonably acceptable to the
Company having capital, surplus and undivided profits of at least
$100,000,000 (the "Exchange Agent"), for the benefit of the holders of
Shares, cash in an aggregate amount equal to the product of (i)the number
of Shares issued and outstanding immediately prior to the Effective Time
(other than any such Shares owned beneficially or of record by Parent or
Mergeco or any other subsidiary of Parent and other than Shares which
continue to be Dissenting Shares immediately prior to the Effective Time),
pro-rated for fractional Shares, if any, and (ii)the Merger Consideration
(such amount being hereinafter referred to as the "Exchange Fund").  The
Exchange Agent shall, pursuant to irrevocable instructions, make the
payments provided for in Section2.1

          (a) of this Agreement out of the Exchange Fund, subject to the
requirements of the remainder of this Section 2.4.  The Exchange Agent
shall invest the Exchange Fund as Parent directs, in direct obligations of
the United States of America, obligations for which the full faith and
credit of the United States of America is pledged to provide for the
payment of all principal and interest, commercial paper obligations
receiving the highest rating from either Moody's Investors Services, Inc.
or Standard & Poor's Corporation, or certificates of deposit, bank
repurchase agreements or banker's acceptances of commercial banks with
capital exceeding $100,000,000 or in money market funds which are invested
solely in the permitted investments set forth above (collectively, the
"Permitted Investments"); provided, however, that the maturities of
Permitted Investments shall be such as to permit the Exchange Agent to make
prompt payment to former holders of the Shares entitled thereto as
contemplated by this Section 2.4.  The Exchange Fund shall not be used for
any other purpose except as provided in this Agreement.  Notwithstanding
anything to the contrary set forth in this Agreement, the Exchange Agent
shall be permitted and required, upon the request of Parent, to remit from
time to time to Parent all interest or other income derived from the
investments constituting the Exchange Fund.  The Surviving Corporation
shall cause the Exchange Fund to be promptly replenished to the extent of
any losses incurred as a result of the Permitted Investments.  If for any
reason (including losses) the Exchange Fund is inadequate to pay the
amounts to which holders of Shares shall be entitled under Section 2.1 and
this Section 2.4, the Surviving Corporation shall in any event be liable
for payment thereof.

          (b)  As soon as practical after the Effective Time, the Surviving
Corporation shall cause the Exchange Agent to mail to each record holder
(other than Parent, Mergeco or any other subsidiary of Parent and other
than with respect to Dissenting Shares unless and until they cease to be
Dissenting Shares) as of the Effective Time of an outstanding certificate
or certificates which immediately prior to the Effective Time represented
Shares (the "Certificates") a form letter of transmittal (which shall
specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon proper delivery of the Certificates to
the Exchange Agent) and instructions for use in effecting the surrender of
the Certificates for payment therefor.  Upon, and only upon, surrender to
the Exchange Agent of a Certificate, together with such letter of
transmittal duly executed, and any other items specified in such letter of
transmittal as may be reasonably requested by the Exchange Agent, the
holder of such Certificate shall be entitled to receive in exchange
therefor payment by check or draft in an amount equal to the product of the
number of Shares represented by such Certificate (pro-rated for fractional
Shares, if any) and the Merger Consideration, less any applicable
withholding tax, and such Certificate shall forthwith be canceled.  No
interest shall be paid or accrued on the amount payable upon the surrender
of the Certificates.  If payment is to be made to a person other than the
person in whose name the Certificate surrendered is registered, it shall be
a condition of payment that the Certificate so surrendered shall be
properly endorsed or otherwise be in proper form for transfer and that the
person requesting such payment shall pay any transfer or other taxes
required by reason of the payment to a person other than the registered
holder of the Certificate surrendered or establish to the satisfaction of
the Exchange Agent and the Surviving Corporation that such tax has been
paid or is not applicable.  Until surrendered in accordance with the
provisions of this Section2.4, each Certificate (other than Certificates
representing Shares owned beneficially or of record by Parent, Mergeco or
any other subsidiary of Parent and other than Certificates representing
Dissenting Shares in respect of which dissenters' rights are perfected and
have not been lost or withdrawn) shall represent for all purposes only the
right to receive the Merger Consideration in cash multiplied by the number
of Shares evidenced by such Certificate, without any interest thereon.

          (c)  In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the holder
claiming such Certificate to have been lost, stolen or destroyed, the
amount to which such holder would have been entitled under Section 2.4(b)
hereof but for failure to deliver such Certificate to the Exchange Agent
shall nevertheless be paid to such holder, provided that the Surviving
Corporation may, in its sole discretion and as a condition precedent to
such payment, require such holder to give the Surviving Corporation a bond
in such sum as it may reasonably direct as indemnity against any claim that
may be had against the Surviving Corporation with respect to the
Certificate alleged to have been lost, stolen or destroyed.

               After the Effective Time there shall be no transfers on the
stock transfer books of the Surviving Corporation of the Shares which were
outstanding immediately prior to the Effective Time.  If, after the
Effective Time, Certificates are presented to the Surviving Corporation,
they shall be canceled and exchanged for cash as provided in this Article
II, subject to applicable law in the case of Dissenting Shares.

               Any portion of the Exchange Fund which remains unclaimed by
the shareholders of the Company after December 31, 1997 (including any
interest received with respect thereto, to the extent not previously
remitted to Parent as contemplated by Section 2.4(a)) shall be repaid to
the Surviving Corporation, upon demand.  Any shareholders of the Company
who have not theretofore complied with Section2.4(b) shall thereafter be
entitled to the payment of the Merger Consideration only from the Surviving
Corporation, without any interest thereon, but shall have no greater rights
against the Surviving Corporation than may be accorded to general creditors
of the Surviving Corporation under relevant law.

               The Surviving Corporation shall pay all charges and
expenses, including those of the Exchange Agent, in connection with the
exchange of cash for Shares.

          2.5  EMPLOYEE STOCK OPTIONS.  Exhibit B to this Agreement sets
forth a true and complete list of all options to purchase Shares
(collectively, the "Options") issued pursuant to the Company's Restated
1986 Stock Option Plan (as amended, the "Stock Option Plan"), setting forth
(i) the identity of each Option holder, (ii) the number of Options held,
(iii) the exercise price of each Option, and (iv) the aggregate number of
Shares subject to Options. Immediately prior to the Effective Time, each
holder of an outstanding Option to purchase Shares granted under the Stock
Option Plan (including, without limitation, Options granted to non-employee
directors of the Company and members of the Company's Scientific Advisory
Board/Panel), whether or not then exercisable, shall be entitled to receive
for each Share subject to such Option, in cancellation of such Option, an
amount in cash equal to the excess, if any, of the Merger Consideration
over the per Share exercise price of such Option without interest thereon,
subject to all applicable tax withholding requirements, and such Option
shall thereupon be canceled.


                                ARTICLE III

               REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company represents and warrants to Parent and Mergeco as
follows:

          3.1  ORGANIZATION.  The Company and each of its subsidiaries is a
corporation duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation and has all requisite
corporate power and corporate authority to own, lease and operate its
properties and to conduct its business as now being conducted, except where
the failure to be so organized, existing and in good standing or to have
such power and authority would not, individually or in the aggregate, have
a material adverse effect on the business or condition (financial or
otherwise), properties or assets of the Company and its subsidiaries taken
as a whole (a "Material Adverse Effect").  Each of the Company and its
subsidiaries is duly qualified or licensed and in good standing to do
business in each jurisdiction in which the property owned, leased or
operated by it or the nature of the business conducted by it makes such
qualification necessary, except where the failure to be so qualified or
licensed and in good standing would not, individually or in the aggregate,
have a Material Adverse Effect.  Section 3.1 of the Company's disclosure
schedule, dated the date hereof and delivered to Parent (the "Disclosure
Schedule") sets forth a true and complete list of the Company's
subsidiaries, listing, for each subsidiary, (i) its name, (ii) its
jurisdiction of incorporation, (iii) the names and titles of its directors
and executive officers and (iv) the number and percentage of shares of such
subsidiary's capital stock owned of record by the Company or another
subsidiary of the Company, and except as and to the extent set forth in
Section 3.l of the Disclosure Schedule, the Company owns, of record or
beneficially, directly or indirectly, all of the issued and outstanding
capital stock of each of its subsidiaries, free and clear of all liens,
pledges, security interests, claims or other encumbrances.  Except for
capital stock of the subsidiaries listed in Section 3.1 of the Disclosure
Schedule, the Company owns no equity securities of any entity. The Company
has heretofore delivered to Parent accurate and complete copies of the
Articles of Incorporation and the Amended By-Laws (or equivalent
organizational documents) of the Company and each of its subsidiaries, as
currently in effect.

          3.2  CAPITALIZATION.  The authorized capital stock of the Company
consists of 30,000,000 shares, (i) 25,000,000 of which are designated as
Common Stock, of which, on the date hereof, there were 16,505,486 Shares
issued and outstanding, 1,200,000 Shares reserved for issuance under the
Stock Option Plan and 730,720 Shares subject to issuance upon exercise of a
like number of warrants evidenced by a Warrant Certificate dated as of
December 13, 1989 (the "Warrants"), and (ii) 5,000,000 of which are
divisible into such classes and series, with such designations, voting
rights and other rights and preferences as the Board of Directors of the
Company (the "Board of Directors") may from time to time determine
(consistent with paragraphs (a) and (b) of Article VII of the Company's
Articles of Incorporation), of which, on the date hereof, there are no
shares issued or outstanding, and no shares have been designated by the
Board of Directors as to classes or series.  The Company has not acquired,
redeemed or repurchased any Shares or other shares of capital stock of the
Company that have been pledged by the Company as security for future
payment of all or part of the purchase price for such Shares or other
shares of capital stock.  All issued and outstanding Shares are duly
authorized, validly issued, fully paid and nonassessable and have no
preemptive rights (other than preemptive rights created pursuant to the
Purchase Rights Agreement, dated as of December 13, 1989 (the "Purchase
Rights Agreement"), between the Company and Biofin Holding International
B.V. ("Biofin")).  Except for (i) the Warrants, (ii) Options granted
pursuant to the Stock Option Plan to acquire not more than 669,640 Shares,
as set forth on Exhibit B hereto, and (iii) preemptive rights created
pursuant to the Purchase Rights Agreement, there are not now, and at the
Effective Time there will not be, any existing options, warrants, calls,
subscriptions, preemptive rights or other rights or other agreements or

          3.9  EMPLOYEE AGREEMENTS AND PLANS. (a) Except as set forth in
Section 3.9 (a) of the Disclosure Schedule, with respect to any employee or
former employee of the Company, neither the Company nor any ERISA Affiliate
presently maintains, contributes to or has any liability under:

          (i)  any bonus, incentive compensation, profit sharing,
     retirement, pension, group insurance, death benefit, health,
     cafeteria, flexible benefit, medical expense reimbursement, dependent
     care, stock option, stock purchase, stock appreciation rights,
     savings, deferred compensation, consulting, severance pay or
     termination pay, vacation pay, life insurance, welfare or other
     employee benefit or fringe benefit plan, program or arrangement; or

          (ii) any plan, program or arrangement which is an "employee
     pension benefit plan" as such term is defined in Section 3(2) of
     ERISA, or an "employee welfare benefit plan" as defined in Section
     3(1) of ERISA.

Each plan, program and arrangement set forth in Section 3.9 (a) of the
Disclosure Schedule is herein referred to as an "Employee Benefit Plan."
For purposes of this Agreement, the term "ERISA Affiliate" shall mean any
person (as defined in Section 3(9) of ERISA) that together with the Company
(or any person whose liabilities the Company has assumed or is otherwise
subject to) would be treated as a single employer under Section 4001(b) of
ERISA, or would be aggregated with the Company under Sections 414(b), (c),
(m) or (o) of the Code.  Within the last twenty-four months neither the
Company nor any ERISA Affiliate has entered into any formal plan or
commitment, or has communicated to any current or former employee any
intention, whether legally binding or not, to create any additional
material Benefit Plan.

          (b)  A favorable determination letter has been received from the
Internal Revenue Service with respect to each Employee Benefit Plan which
is intended to comply with the provisions of Section 401(a) of the Code.
Each such Employee Benefit Plan complies in form and in operation in all
material respects with the requirements of the Code and meets the
requirements of a "qualified plan" under Section 401(a) of the Code.  In
addition, amendments have been made to each such Employee Benefit Plan
evidencing substantial compliance with the Tax Reform Act of 1986, as
amended.  Each Employee Benefit Plan subject to Sections 401(k) and 401(m)
of the Code satisfies the average deferral percentage test and the average
contribution percentage test under Sections 401(k) and 401(m) of the Code
for the applicable plan year preceding the plan year in which the Closing
Date occurs.  No event has occurred and no condition exists which could
reasonably be expected to result in the revocation of any previously-issued
determination letter or the denial of any determination letter application.

          (c)  Except as set forth in Section 3.9 (c) of the Disclosure
Schedule, with respect to each Employee Benefit Plan which is subject to
Title I of ERISA, neither the Company nor any ERISA Affiliate has failed to
comply in any material respect with any of the applicable reporting,
disclosure or other requirements of ERISA and the Code and there has been
no "prohibited transaction" as described in Section 4975 of the Code or
Section 406 of ERISA.

          (d)  Neither the Company nor any ERISA Affiliate, nor any of
their respective directors, officers, employees or any other "fiduciary,"
as such term is defined in Section 3(21) of ERISA, has any material
liability for failure to comply with ERISA or the Code for any action or
failure to act in connection with the administration or investment of any
of the Employee Benefit Plans.  No event has occurred with respect to which
the Company or any ERISA Affiliate could be liable for a civil penalty or
other liability under Section 502(c) or Section 502(l) of ERISA, except for
liabilities which would not, individually or in the aggregate, have a
Material Adverse Effect.

          (e)  No Employee Benefit Plan is subject to Section 412 of the
Code or Section 302 of ERISA.  If contributions with respect to each
Employee Benefit Plan are intended to be tax-deductible, all reasonable
actions required to be taken to make such contributions tax-deductible have
been taken.  Further, all applicable contributions and premium payments for
all periods ending prior to the Closing Date (including periods from the
first day of the then current plan year to the Closing Date) shall be or
have been made prior to the Closing Date in accordance with past practice,
except for contributions and premium payments not due prior to the Closing
Date (for which appropriate reserves have been taken).  No Employee Benefit
Plan is subject to Title IV of ERISA.  Neither the Company nor any ERISA
Affiliate has terminated any employee pension benefit plan subject to Title
IV of ERISA within the past eight years.  Except as set forth in Section
3.9 (e) of the Disclosure Schedule, no Employee Benefit Plan has any
unfunded liability.  The financial records of each Employee Benefit Plan
have been kept in accordance with GAAP.

          (f)  Neither the Company nor any ERISA Affiliate has any
liability (including current or potential withdrawal liability) with
respect to any "multiemployer plan" as such term is defined in Section
3(37) of ERISA, other than the obligation to make periodic contributions
with respect to those Employees covered by any such plan.

               There is no pending or threatened legal action, claim,
proceeding or investigation against or involving any Employee Benefit Plan
and, to the knowledge of Company and each ERISA Affiliate, there is no
basis for, and the Company has no knowledge of any facts which could give
rise to, any such condition, legal action, claim, proceeding or
investigation, other than routine claims for benefits and other claims,
none of which routine and other claims would, individually or in the
aggregate, have a Material Adverse Effect.  Any bonding required with
respect to any Employee Benefit Plan in accordance with applicable
provisions of ERISA has been obtained and is in full force and effect.

               Except as set forth in Section 3.9 (h) of the Disclosure
Schedule, with respect to any employee or former employee of the Company,
neither the Company nor any ERISA Affiliate presently maintains,
contributes to or has any liability under any funded or unfunded medical,
health or life insurance plan or arrangement for terminated employees or
retirees except as required by the Consolidated Omnibus Budget
Reconciliation Act of 1985, as amended.  Neither the Company nor any ERISA
Affiliate maintains or contributes to a trust, organization or association
described in any of Sections 501(c)(9), 501(c)(17) or 501(c)(20) of the
Code.

               Except as set forth in Section 3.9 (i) of the Disclosure
Schedule,

                                   Neither the Company nor any ERISA
          Affiliate is a party to any employment agreement, whether written
          or oral, or agreement with change-in-control or similar
          provisions, or collective bargaining agreement or contract with
          any labor union relating to any employees or former employees;

                                   The consummation of the transactions
          contemplated by this Agreement will not entitle any individual to
          severance pay or accelerate the time of payment or vesting, or
          increase the amount, of compensation or benefits due to any
          individual; and

                                   Neither the Company nor any ERISA
          Affiliate has currently outstanding any loan or loans to any
          current or former employees, nor has the Company nor any ERISA
          Affiliate guaranteed such loans.

               There has been no act or acts which would result in a
disallowance of a deduction or the imposition of a tax pursuant to Section
4980B of the Code, or any predecessor provision thereof, or any regulations
promulgated thereunder, whether final, temporary or proposed.

               With respect to each Employee Benefit Plan, the Company has
delivered to Parent accurate and complete copies of the following (where

alleges that any of the Company's corporate predecessors was not in

          3.14 OPINION OF FINANCIAL ADVISOR.  The Company has received the
written opinion of Cowen & Company, its financial advisor, to the effect
that the consideration to be received in the Merger by the Company's
shareholders is fair to the Company's shareholders, other than Biofin, from
a financial point of view, a copy of which opinion has been delivered to
Parent.

          3.15 CERTAIN ANTI-TAKEOVER PROVISIONS NOT APPLICABLE.  The Board
of Directors and the Special Committee have each approved the Merger and
this Agreement, such Special Committee has been duly constituted pursuant
to Section 302A.673 of the MBCA and consists only of, and includes all,
disinterested directors as defined therein and such approval by the Special
Committee is sufficient to render inapplicable to this Agreement and the
Merger the restrictions on business combinations (as defined in Section
302A.011 of the MBCA) contained in Section 302A.673 of the MBCA.  The
Merger does not constitute a "control share acquisition" subject to the
provisions of Section 302A.671 of the MBCA, by virtue of Section 302A.011,
Subd. 38(d) of the MBCA.  Except for any state takeover statutes (of a
state or states other than Minnesota), the purported application of which
would not reasonably be expected to prevent or materially delay the Merger,
no other state takeover statute or similar statute or regulation in any
jurisdiction in which the Company or any of its subsidiaries does business,
applies or purports to apply to the Merger or to this Agreement, or any of
the transactions contemplated hereby.  The representations and warranties
contained in this Section 3.15 are based upon the assumption of the
accuracy of the representations contained in Section 4.8 hereof.

          3.16 INTELLECTUAL PROPERTY. (a) Section 3.16(a)-Part I of the
Disclosure Schedule sets forth an accurate list of all patents, patent
applications, registered trademarks, registered trade names, and other
material trademarks, registered service marks, registered trade names, and
registered copyrights which are owned by the Company and/or its
subsidiaries and used in the conduct of their business.  Section 3.16(a)-
Part II of the Disclosure Schedule sets forth an accurate list of all
licenses to the Company and/or its subsidiaries licensing rights under
patents, patent applications and/or know-how used by the Company and/or its
subsidiaries in the conduct of their business. There are no patents, patent
applications, registered trademarks, registered service marks or registered
trade names or other material trademarks, registered service marks or
registered trade names used by the Company and/or its subsidiaries in the
conduct of their business which are not listed in Section 3.16(a) of the
Disclosure Schedule.  To the knowledge of the Company, all the patents and
registered trademarks listed in Section 3.16(a) of the Disclosure Schedule
are valid.  All patents, patent applications and registered trademarks
listed in Section 3.16(a) of the Disclosure Schedule are in good standing.
All fees (including annuity fees) due to applicable patent and trademark
offices in respect to such patents, patent applications, and registered
trademarks and payable by the Closing Date have been paid or will be paid
prior to the Closing Date.  All renewals of registered trademarks listed in
Section 3.16(a) of the Disclosure Schedule have been effected in due time.
To the knowledge of the Company, no third party is infringing any patent,
trademark, trade name or service mark set forth in Section 3.16(a) of the
Disclosure Schedule.

          (b)  No claim has been made by any third party to the Company
and/or its subsidiaries that any patent, trademark, trade name or service
mark set forth in Section 3.16(a) of the Disclosure Schedule is invalid or
that the exercise of the rights thereto constitutes any form of unfair
competition.

          (c)  None of the Company nor any of its subsidiaries has done or
committed any act that to the knowledge of the Company has impaired or will
impair the validity of the patents, trademarks, service marks and trade
names set forth in Section 3.16(a) of the Disclosure Schedule so as to have
a Material Adverse Effect.

          (d)  Except as set forth in Section 3.16(d) of the Disclosure
Schedule, the Company and/or its subsidiaries have not granted any
license(s) under any of the patents, patent applications, trade marks,
service marks or trade names set forth in Section 3.16(a) of the Disclosure
Schedule.  The Company and/or its subsidiaries own or have acquired a right
from third parties to use all know-how used by the Company and/or its
subsidiaries in the conduct of their business and such rights will not be
impaired by the Merger or the consummation of the other transactions
contemplated hereby.

          (e)  No claims for infringement of any patents, trademarks, trade
names or service marks are pending or known by the Company and/or its
subsidiaries to be threatened in writing (i) against the Company and/or its
subsidiaries, or (ii) to the knowledge of the Company, with respect to any
of the products of the Company and/or its subsidiaries (other than products
sold pursuant to the agreements listed in Section 3.16(a)-Part II(B)),
against any of their respective customers.

          3.17 LICENSES AND PERMITS. (a) The Company and its subsidiaries
have all governmental licenses and permits necessary to conduct their
business as currently conducted and to own and operate their assets, and
such licenses and permits are valid and in full force and effect except
where the failure to have such governmental licenses and permits would not
have a Material Adverse Effect.  No defaults or violations exist or have
been recorded in respect of any governmental license or permit of the
Company and its subsidiaries other than defaults or violations which would
not have a Material Adverse Effect.  Except to the extent it would not
reasonably be expected to have a Material Adverse Effect, no proceeding is
pending or, to the knowledge of the Company, threatened looking toward the
revocation, limitation or non-renewal of any such governmental license or
permit.

          (b)  The Company has delivered or made available for inspection
to Parent a true and complete copy of each material governmental license
and permit, and each pending application for any material governmental
license or permit, including all amendments and supplements thereto and
modifications thereof, relating to the Company and its subsidiaries.
Except to the extent that they would not reasonably be expected to have a
Material Adverse Effect, (i) all of such pending applications are, to the
knowledge of the Company, in good standing and without challenge of any
kind; (ii) each statement, application and other document submitted or
filed by the Company or any subsidiary to or with any federal, state or
other governmental agency or authority, or to or with any other person or
entity, for purposes of obtaining a new or renewed lease, license or permit
of any type described in this subsection in connection with the
transactions contemplated hereby is complete and accurate; and (iii)
subject to the receipt of any consents specified in Section 3.4 of the
Disclosure Schedule, none of the rights of the Company or any subsidiary
under any governmental license or permit will be impaired by the
consummation of the Merger or the other transactions contemplated hereby.

          3.18 INSURANCE.  As of the date hereof, the Company and each of
its subsidiaries are insured by insurers, reasonably believed by the
Company to be of recognized financial responsibility and solvency, against
such losses and risks and in such amounts as are customary in the
businesses in which they are engaged.  All material policies of insurance
and fidelity or surety bonds insuring the Company or any of its
subsidiaries or their respective business, assets, employees, officers and
directors have previously been made available for inspection by Parent and
are in full force and effect.  As of the date hereof, there are no material
claims by the Company or any subsidiary under any such policy or instrument
as to which any insurance company is denying liability or defending under a
reservation of rights clause.  All necessary notifications of claims have
been made to insurance carriers other than those which will not have a
Material Adverse Effect.

          3.19 CONTRACTS.  All contracts, agreements, commitments and other
documents to which the Company or any subsidiary is a party or by which the
Company, any subsidiary, or any of their assets is in any way affected or
subject, including all amendments and supplements thereto and modifications
thereof, of a nature specified in Exhibit C hereto (collectively, the
"Material Contracts"), are legally valid and binding and in full force and
effect except where failure to be legally valid and binding and in full
force and effect would not have a Material Adverse Effect, and there are no
defaults thereunder by the Company or its subsidiaries or, to the Company's
knowledge, by any other party thereto, except those defaults that would not
have a Material Adverse Effect.  The Company has previously made available
for inspection by Parent all written Material Contracts (and, to the extent
a Material Contract is oral, a true and complete summary of all material
terms thereof).

          3.20 VOTE REQUIRED.  The affirmative vote of the holders of a
majority of the outstanding Shares is the only vote of the holders of any
class or series of the Company's capital stock necessary to approve the
Merger, this Agreement and the transactions contemplated hereby (assuming
for purposes of this representation, the accuracy of the representations
contained in Section 4.8 hereof).

          3.21 FINDERS AND INVESTMENT BANKERS.  All negotiations relating
to this Agreement and the transactions contemplated hereby have been
carried on without the intervention of any person acting on behalf of the
Company in such manner as to give rise to any valid claim against Parent,
Holdings, Mergeco or the Company for any broker's or finder's fee or
similar compensation, except for Cowen & Company, whose fees (which have
been described in a writing furnished by the Company to Parent) shall be
paid by the Company.

restrictions, inchoate mechanic's and workmen's and other similar liens

property subject thereto, (ii) there are no leases, subleases, licenses,
concessions, or other agreements, written or oral, granting to any party or
parties the right of use or occupancy of any portion of the parcel of real
property that would materially interfere with the Company's use of such
property, and (iii) there are no outstanding options or rights of first
refusal to purchase, lease or occupy the parcel of real property, or any
portion thereof or interest therein which would materially interfere with
the Company's use of such property.

represents and warrants that it is not relying upon any representations and
warranties of Parent, Holdings or Mergeco that are not contained in this
Agreement or in the Exhibits hereto and agrees that there shall not be

                                ARTICLE IV

                      REPRESENTATIONS AND WARRANTIES
                           OF PARENT AND MERGECO

          Parent and Mergeco each jointly and severally represent and
warrant to the Company as follows:

          4.1  ORGANIZATION.  Each of Parent, Holdings and Mergeco is a
corporation duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation and each has all requisite
corporate power and corporate authority to own, lease and operate its
properties and to conduct its business as now being conducted, except where
the failure to be so organized, existing and in good standing or to have
such power and authority would not, individually or in the aggregate, have
a material adverse effect on the business or financial condition of Parent
and its subsidiaries taken as a whole.  Each of Parent, Holdings and
Mergeco is duly qualified or licensed and in good standing to do business
in each jurisdiction in which the properties owned, leased or operated by
it or the nature of the business conducted by it makes such qualification
necessary, except where the failure to be so qualified or licensed and in
good standing would not individually or in the aggregate have a material
adverse effect on the business or financial condition of Parent and its
subsidiaries taken as a whole.  Holdings is a wholly owned subsidiary of
Parent, and Mergeco is a wholly-owned subsidiary of Holdings.

          4.2  AUTHORIZATION OF THIS AGREEMENT.  Each of Parent, Holdings
and Mergeco has all requisite corporate power and corporate authority to
execute and deliver this Agreement and to consummate the transactions
contemplated hereby.  The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby have been duly and
validly authorized and approved by the Boards of Directors of Parent,
Holdings and Mergeco and by Holdings as the sole shareholder of Mergeco,
and no other corporate proceedings on the part of Parent, Holdings or
Mergeco are necessary to authorize this Agreement or consummate the
transactions contemplated hereby.  No vote of Parent's shareholders is
required to approve this Agreement or the transactions contemplated
thereby.  This Agreement has been duly and validly executed and delivered
by each of Parent, Holdings and Mergeco and, assuming the accuracy of the
representations and warranties set forth in Section 3.3, constitutes a
valid and binding agreement of Parent, Holdings and Mergeco enforceable

the listing requirements of the NASD and the Nasdaq National Market and
(vi)filings in connection with any applicable transfer or other taxes in
any applicable jurisdiction, no filing with, and no permit, authorization,
consent or approval of, any public body or other governmental authority is
necessary for the consummation by Parent, Holdings and Mergeco of the
transactions contemplated by this Agreement, the failure of which to obtain
is reasonably likely to impair the ability of Parent, Holdings or Mergeco
to perform their respective obligations hereunder or to consummate the
transactions contemplated hereby.  Neither the execution and delivery of
this Agreement nor the consummation of the transactions contemplated hereby
nor compliance by Parent, Holdings or Mergeco with any of the provisions
hereof will (i)conflict with or result in any violation of any provision of
the Certificate or Articles of Incorporation or By-Laws of Parent, Holdings
or Mergeco, (ii)result in a violation or breach of, or constitute a default
(or give rise to any right of termination, cancellation or acceleration)
under, any note, bond, mortgage, indenture, license, agreement or other
instrument or obligation to which Parent or any of its subsidiaries is a
party, or by which any of them or any of their respective properties or
assets is bound, or (iii)assuming the truth of the representations and
warranties of the Company hereunder and its compliance with all agreements
contained herein and assuming the due making or obtaining of all filings,
permits, authorizations, consents and approvals referred to in the
preceding sentence, violate any statute, rule, regulation, order,
injunction, writ or decree of any public body or authority by which Parent
or any of its subsidiaries or any of their respective properties or assets
is bound, excluding from the foregoing clauses(ii) and (iii) violations,
breaches or defaults which, either individually or in the aggregate, are
not reasonably likely to impair the ability of Parent, Holdings or Mergeco
to perform their respective obligations hereunder or to consummate the
Merger or the other transactions contemplated hereby.

          4.4  PROXY STATEMENT.  None of the information supplied or to be
supplied in writing by Parent, Holdings or Mergeco specifically for
inclusion in the Proxy Statement will, at the time the Proxy Statement is
mailed, contain any untrue statement of a material fact, or omit to state
any material fact required to be stated therein or necessary in order to
make the statements therein, in light of the circumstances under which they
were made, not misleading or, at the time of the meeting of shareholders to
which such Proxy Statement relates or at the Effective Time, as then
amended or supplemented, omit to state any material fact necessary to
correct any statement which has become false or misleading in any earlier
communication with respect to the solicitation of any proxy for such
meeting.  If at any time prior to the Effective Time, any event relating to
Parent or any of its subsidiaries is discovered which should be set forth
in an amendment of, or a supplement to, such Proxy Statement, Parent shall
promptly so inform the Company and will furnish all necessary information
to the Company relating to such event.

          4.5  FINANCIAL ABILITY TO PERFORM.  Parent and Mergeco have cash
funds available sufficient to make all cash payments required to be made
hereby for Shares in the Merger and to pay all related fees and expenses.

          4.6  FINDERS AND INVESTMENT BANKERS.  All negotiations relating

finder's fee or similar compensation, except for Goldman, Sachs & Co.,
whose fees shall be paid by Parent.

          4.7  LITIGATION.  There are no suits, claims, actions,
proceedings or investigations pending or, to the knowledge of Parent,
threatened against, Parent, Holdings or Mergeco that, individually or in
the aggregate, would reasonably be expected to delay materially or prevent
the consummation of the Merger or the other transactions contemplated
hereby.

          4.8  CERTAIN ANTI-TAKEOVER PROVISIONS NOT APPLICABLE.  Neither
Parent, Holdings nor Mergeco nor any affiliate or associate of any of the
foregoing persons was an "interested shareholder" of the Company as defined

Holdings' and Mergeco's execution and delivery of this Agreement.

and Mergeco represent and warrant that they are not relying upon any
representations and warranties of the Company that are not contained in
this Agreement or in the Exhibits hereto or in the Disclosure Schedule and

Mergeco, by executing this Agreement consents to the execution and delivery
of this Agreement by Mergeco and the consummation of the Merger and the
other transactions contemplated hereby and such consent shall be treated

Mergeco held for such purpose.

          5.8  NO SOLICITATION. From and after the date hereof until the
earlier of the Effective Time or the termination of this Agreement, neither
the Company nor any of its subsidiaries nor any of their respective
officers, directors, employees, agents or representatives (including,
without limitation, investment bankers, attorneys and accountants) shall,
directly or indirectly, (i)solicit, initiate or encourage or (ii)enter into
any discussions or negotiations with, in any way continue any discussions
or negotiations commenced before the date of this Agreement with, or
disclose directly or indirectly any information not customarily disclosed
concerning its business and properties to, or afford any access to its
properties, books and records to, any corporation, partnership or other
person or group in connection with any possible proposal (an "Acquisition
Proposal") regarding a sale of all or any part of the Company's capital
stock or a merger, consolidation or statutory share exchange involving the
Company or any subsidiary of the Company or sale or spin-off of all or a
substantial portion of the assets of the Company or any subsidiary of the
Company which is material to the Company and its subsidiaries taken as a
whole, or a liquidation or a recapitalization of the Company, or any
similar transaction; provided that (x)in response to an Acquisition
Proposal made without such solicitation, initiation or encouragement, the
Company may (if the Board of Directors shall have concluded in good faith,
based on the advice of outside counsel that any action is required for the
Board of Directors to comply with its fiduciary duties under applicable
law) (i)furnish information with respect to the Company to any person
pursuant to a confidentiality agreement no more favorable to such person
than the Confidentiality Agreement is to Parent and (ii)participate in
negotiations regarding such Acquisition Proposal and (y)the Board of
Directors shall be free to take and disclose any position with respect to a
third party offer pursuant to Rules l4d-9 and l4e-2 under the Exchange Act
and make such disclosures to the Company's shareholders, which, upon the
advice of outside counsel, is required by applicable law.  The Company will
notify Parent immediately, orally and in writing, if any discussions or
negotiations are sought to be initiated, any inquiry or proposal is made,
or any such information is requested, with respect to an Acquisition
Proposal or potential Acquisition Proposal or if any Acquisition Proposal
is received or indicated to be forthcoming, and will include in such
notification the identity of the other party or parties and the material
terms and conditions of any such request, inquiry or Acquisition Proposal.
The Company will keep Parent fully informed of the status and details
(including amendments or proposed amendments) of any such request, inquiry
or Acquisition Proposal.

          (b)  If the Board of Directors, after consultation with and based
upon the advice of outside counsel, determines in good faith that it is
necessary to do so in order to comply with its fiduciary duties under
applicable law, the Board of Directors, (i) may modify or amend its
approval or recommendation of this Agreement or Merger, (ii) approve or
recommend any Superior Proposal (as hereinafter defined) or (iii) following
the termination of this Agreement in accordance with its terms, enter into
an agreement with respect to a Superior Proposal; provided, however, in
case of clauses (ii) and (iii) only at a time after the second business day
after Parent's receipt of written notice from the Company advising Parent
of the Company's receipt of a Superior Proposal, specifying the material
terms and conditions of such Superior Proposal and identifying the person
making such Superior Proposal. For purposes of this Agreement, a "Superior
Proposal" means a proposal to acquire, directly or indirectly, more than
50% of the Shares or all or any substantial portion of the consolidated
assets of the Company and its subsidiaries and otherwise on terms that the
Board of Directors determines in its good faith judgment (based on the
advice of a financial advisor of nationally recognized reputation) to be
more favorable to the Company's shareholders than the Merger.

          5.9  INDEMNIFICATION. (a) For a period of six years after the
Effective Time, the Surviving Corporation shall indemnify, defend and hold
harmless the present and former officers, directors, employees and
committee members of the Company and its subsidiaries (collectively, the
"Indemnified Parties") from and against, and pay or reimburse the
Indemnified Parties for judgments, penalties, fines, settlements and
expenses, including attorneys fees and disbursements resulting from or
arising out of actions or omissions occurring at or prior to the Effective
Time (including, without limitation, the transactions contemplated by this
Agreement) by such persons in their capacities as officers, directors,
employees or committee members of the Company or any of its subsidiaries to
the full extent permitted or required under applicable law and to the
extent permitted under the provisions of the Articles of Incorporation and
the Amended By-Laws of the Company in effect at the date hereof (which
provisions shall not be amended in any manner which adversely affects any
Indemnified Party, for a period of six years), including provisions
relating to advances of expenses incurred in the defense of any proceeding;
provided that in the event any claim or claims are asserted or made within
such six-year period, all rights to indemnification in respect of each such
claim shall continue until final disposition of such claim.

          (b)  Any Indemnified Party wishing to claim indemnification under
Section 5.9(a) shall provide notice to the Surviving Corporation promptly
after such Indemnified Party has actual knowledge of any claim as to which
indemnity may be sought, and the Indemnified Party shall permit the
Surviving Corporation (at the Surviving Corporation's expense) to assume
the defense of any claim or any litigation resulting therefrom; provided
that (i)counsel for the Surviving Corporation who shall conduct the defense
of such claim or litigation shall be reasonably satisfactory to the
Indemnified Party, and the Indemnified Party may participate in such
defense at such Indemnified Party's expense, and (ii)the omission by any
Indemnified Party to give notice as provided herein shall not relieve the
Surviving Corporation of its indemnification obligation under this
Agreement except to the extent that such omission results in a failure of
actual notice to the Surviving Corporation and the Surviving Corporation is
materially damaged as a result of such failure to give notice.  The
Surviving Corporation shall not, in the defense of any such claim or
litigation, except with the consent of the Indemnified Party, consent to
entry of any judgment or enter into any settlement that provides for
injunctive or other nonmonetary relief affecting the Indemnified Party or
that does not include as an unconditional term thereof the giving by the
claimant or plaintiff to such Indemnified Party of a release from all
liability with respect to such claim or litigation.  In the event that the
Surviving Corporation does not accept the defense of any matter as above
provided, or counsel for the Indemnified Parties advises that there are
issues which raise conflicts of interest between the Surviving Corporation
and the Indemnified Parties, the Indemnified Parties may retain counsel
satisfactory to them, and the Surviving Corporation shall pay all
reasonable fees and expenses of such counsel for the Indemnified Parties
promptly as statements therefor are received; provided that the Surviving
Corporation shall not be liable for any settlement effected without its
prior written consent (which consent shall not be unreasonably withheld,
provided that such settlement does not in any way require the Surviving
Corporation to make any admission of liability with respect to such claim
or litigation).  In any event, the Surviving Corporation and the
Indemnified Parties shall cooperate in the defense of any action or claim
subject to this Section5.9 and the records of each shall be available to
the other with respect to such defense.

          (c)  For a period of six years after the Effective Time, the
Surviving Corporation shall cause to be maintained in effect either (i) the
current policy of directors' and officers' liability insurance maintained
by the Company (provided that Parent or the Surviving Corporation may
substitute therefor policies of at least the same coverage and amounts
containing terms and conditions which are no less advantageous in any
material respects to the Indemnified Parties) with respect to claims
arising from facts or events which occurred before the Effective Time;
provided, however, that in no event shall the Surviving Corporation be
required to expend pursuant to this Section 5.9(c)(i) more than an amount
per year equal to 150% of the current annual premium (which current annual
premium for the policy year ending September 1, 1997 the Company represents
and warrants to be approximately $47,355 in the aggregate) paid by the
Company for such existing insurance coverage (the "Cap"); and provided,
further, that if equivalent coverage cannot be obtained, or can be obtained
only by paying an annual premium in excess of the Cap, the Surviving
Corporation shall only be required to obtain as much coverage as can be
obtained by paying an annual premium equal to the Cap, or (ii) a run-off
(i.e., "tail") policy or endorsement with respect to the current policy of
directors' and officers' liability insurance covering claims asserted
within six years after the Effective Time arising from facts or events
which occurred before the Effective Time.

          (d)  The provisions of this Section 5.9 are intended to be for
the benefit of, and shall be enforceable by, each Indemnified Party, his or
her heirs and his or her personal representatives and shall be binding on
all successors and assigns of the Surviving Corporation.

          5.10 TRANSFER TAXES.  The Surviving Corporation shall pay any
transfer Taxes payable in connection with the Merger and shall be
responsible for the preparation and filing of any required Tax Returns with
respect to such Taxes.

          5.11 ANTI-TAKEOVER STATUTES.  If any "fair price", "moratorium",
"control share acquisition" or other form of anti-takeover statute is or
shall become applicable to the Merger or the other transactions
contemplated hereby, the Company and the members of the Board of Directors
and the Special Committee shall, subject to their fiduciary duties under
applicable law as advised by outside counsel, grant such approvals and take
such actions as are necessary so that the Merger and the other transactions
contemplated hereby may be consummated as promptly as practicable on the
terms contemplated hereby and otherwise act to eliminate or minimize the
effects of any such anti-takeover statute on the transactions contemplated
hereby.

          5.12 NOTIFICATION OF CERTAIN MATTERS.  The Company will give
prompt notice to Parent and Mergeco, and Parent and Mergeco will give
prompt notice to the Company, of the occurrence or non-occurrence of any
event (i) which has had a Material Adverse Effect, (ii) which has caused
any representation or warranty contained in this Agreement to be untrue or
inaccurate or (iii) which has caused any failure of the Company, or of
Parent or Mergeco, as the case may be, to in all material respects comply
with or satisfy any covenant, condition or agreement to be complied with or
satisfied under this Agreement; provided, however, that the delivery of any
notice pursuant to this Section 5.12 will not limit or otherwise affect the
remedies available under this Agreement to the party receiving such notice.

          5.13 CERTAIN RESIGNATIONS.  The Company will use all reasonable
efforts to assist Parent in procuring the resignation of all of the members
of the Board of Directors and the directors of all of the Company's
subsidiaries effective as of the Effective Time.

          5.14 EMPLOYEE MATTERS. (a) For a period of two years after the
Effective Time, Parent shall cause the Surviving Corporation (i) to
continue to maintain the Company's individual base salaries (as in effect
immediately prior to the Effective Time) for each employee residing in the
United States and actively employed full-time by the Company immediately
prior to the Effective Time as long as that employee continues to be
actively employed full-time by the Surviving Corporation in the same
capacity as such employee was actively employed full-time by the Company
immediately prior to the Effective Time and (ii) to maintain welfare and
pension benefit plans, programs and arrangements (other than stock based
plans, programs and arrangements) which, in the aggregate, for the
employees as a whole who were active full-time employees of the Company
immediately prior to the Effective Time and continue to be active full-time
employees of the Surviving Corporation, are no less favorable than those
provided by the Company immediately prior to the Effective Time, provided
that nothing herein shall obligate Parent or the Surviving Corporation to
provide such employees with any stock based compensation (including,
without limitation, stock options or stock appreciation rights).

          (b)  From and after the Effective Time, for purposes of
determining eligibility and vesting (but not benefit accrual) for employees
residing in the United States and actively employed full-time by the
Company immediately prior to the Effective Time, under any compensation,
severance, welfare, pension, benefit or savings plan of Parent or any of
its affiliates, in effect on the Effective Time or established within two
years after the Effective Time, in which active full-time employees of the
Company and its subsidiaries become eligible to participate (to the extent
required by clause (ii) of Section 5.14(a) above), service with the Company
or any of its subsidiaries (whether before or after the Effective Time)
shall be credited as if such services had been rendered to Parent or any of
its affiliates.

          (c)  No provision of this Section 5.14 shall create any third
party beneficiary rights in any employee of the Company or its subsidiaries
(including any beneficiary thereof).

          5.15 EXTINGUISHMENT OF CREDIT LINE.  Prior to the Effective Time,
the Company shall terminate its existing line or lines of credit with an
affiliate of Biofin, and there shall not have been any borrowings
thereunder by the Company or any of its subsidiaries from the date hereof
through and including the Effective Time.

provided, that after this Agreement is adopted by the Company's

permits consent by or on behalf of any party hereto, such consent shall be
given in writing in a manner consistent with the requirements for a waiver
of compliance as set forth in this Section9.2.  Each of Holdings and
