ITEM 1 - BUSINESS

                                     GENERAL

Imatron Inc. ("Imatron" or the "Company"), a New Jersey corporation incorporated
in 1983, is a technology-based  company  principally  engaged in the business of
designing,  manufacturing and marketing a high performance  computed  tomography
("CT") scanner.  This scanner uses Electron Beam Tomography  ("EBT")  technology
based on a scanning  electron  beam.  The scanner is used in large and  midsized
hospitals and free-standing imaging clinics. The Company provides service, parts
and maintenance to hospitals and clinics that operate its scanners.

The Company is also engaged in performing research and development for others in
the field of CT devices and  licensing its patents and know-how in the fields of
imaging sciences.

HeartScan Imaging,  Inc.  ("HeartScan"),  incorporated in Delaware in 1993, is a
diagnostic  services  subsidiary of the Company.  After  completion of a private
placement that raised  $14,798,000 in net proceeds in July 1996 and the exercise
of certain  incentive  stock  options by HeartScan and Imatron  management  team
members,  at December 1996,  Imatron has a 49.5%  interest in HeartScan  Imaging
which has been consolidated with Imatron for financial  reporting  purposes as a
result  of  certain  exchange  provisions  included  in  the  private  placement
agreement. HeartScan offers coronary artery scanning ("CAS") and coronary artery
disease risk assessment  services  through its five Coronary Artery Disease Risk
Assessment  Centers in South San  Francisco,  California,  Seattle,  Washington,
Houston,  Texas,  Pittsburgh,  Pennsylvania  and  Washington  D.C.  HeartScan is
engaged in the business of  developing a nationwide  network of coronary  artery
disease risk assessment centers.


                              PRODUCT AND SERVICES

                                 ULTRAFAST CT(R)

PRODUCT DESCRIPTION

A  conventional   CT  scanner  is  a  diagnostic   imaging  device  in  which  a
cross-sectional  (tomographic)  image of a patient's  anatomy is  acquired  from
multiple intensity readings  (samplings) taken as an x-ray source rotates around
the patient  during a scanning  cycle.  The  acquired  x-ray data are  processed
through a complex mathematical algorithm relating variations in the intensity of
x-rays  passing  through a patient's  body to tissue  density  differences.  The
acquired data are subsequently  reconstructed and displayed as images on a video
monitor, typically with white corresponding to high density matter, such as bone
or calcium,  and with black corresponding to low density matter, such as air. In
this  manner,  the  patient's  anatomy  can  be  displayed  in a  succession  of
cross-sectional, anatomical gray-scale representations.

The Imatron Ultrafast CT scanner design differs from conventional CT scanners in
two important ways.  First, the  mechanically  rotating x-ray tube technology of
conventional  CT scanners is replaced by a high power electron beam  accelerator
that  generates a focused,  high-intensity  electron beam which is steered along
stationary  target  rings to  produce a rotating  fan-shaped  x-ray  beam.  This
patented electron beam technology permits significantly faster scan speeds to be
achieved.  The  Company's  scanner  can acquire CT images at a rate of 50 to 100
milliseconds  per slice in contrast to  conventional  CT scanners  that  require
between 1 and 10 seconds per slice.  Second,  the Imatron  Ultrafast  CT permits
rapid scanning of multiple  contiguous  images without moving the patient.  With

<PAGE>

these  features,  the  Ultrafast CT scanner can perform  stop-action  or dynamic
studies of the heart and various  other  organs,  contributing  to the scanner's
usefulness for both diagnostic imaging and functional evaluation.

The Ultrafast  CT(R)  Scanner can be operated in three  scanning  modes:  Single
Slice mode,  Multi-Slice  mode and Continuous  Volume  Scanning mode. The Single
Slice mode can acquire up to 140 images per  acquisition and can be timed to the
heart  cycle  with  ECG  triggering.  This  mode  employs  scan  times  from 100
milliseconds  to 2  seconds  as  compared  to 1 to 4  second  exposure  times of
conventional CT scanners.  The Multi-Slice  mode  incorporates  scan times of 50
milliseconds  and can acquire up to 180 images in 6 seconds.  This mode can also
be timed over the  cardiac  cycle with ECG  triggering.  The  Continuous  Volume
Scanning mode can acquire up to 140 images in 15 seconds.  This  continuous data
acquisition mode of the scanner  outperforms spiral or helical scanning modes on
conventional CT scanners. Advantages include excellent slice registration for 3D
reconstruction,  respiratory motion-free pulmonary imaging,  pediatric scanning,
trauma, IV contrast reduction and increased patient throughput.

PRODUCT DEVELOPMENT

In December  1996,  the Company  completed its version 12.3 software  which more
than  tripled the image  acquisition  capability  on the  Company's  C-150 model
Ultrafast   CT   scanner.   Furthermore,   improvements   were   made  in  image
reconstruction  algorithms,  ECG triggering  capabilities and continuous  volume
scanning  modes.  After  completion of Beta testing in early 1997,  version 12.3
software will be available for sale.

In  addition,  the  Company  began  marketing  its new  workstation,  which when
connected  to the  scanner,  increases  the  functionality  and  flexibility  of
cross-sectional  scanning. Images can now be viewed in 2D, 3D, Maximum Intensity
Projections and real-time Multi-planar  reformatting.  This workstation can also
perform  auto  filming,   auto   archiving  and  DICOM   (digital   imaging  and
communications in medicine)  transfer.  The Company believes this  multi-tasking
feature, along with superior image display and manipulation  capabilites creates
a workstation  which will provide the user with  increased  capacity to process,
view, manipulate and store the data produced by the Ultrafast CT scanner.

MARKETS

The Company sells its CT scanner to the diagnostic medical imaging market.  This
market  includes  several  different  medical  imaging  modalities  such  as CT,
ultrasound,  nuclear  medicine,  digital  subtraction  angiography  and magnetic
resonance  imaging.  These  imaging  modalities  are based  upon the  ability of
x-rays, sound waves, gamma rays or magnetic fields to penetrate human tissue and
be  detected  by  electronic  devices  for  presentation  of an image on a video
monitor.  In some cases,  these imaging  modalities compete with one another for
the same type of diagnostic procedure.

All of these systems have been  evaluated in the diagnosis of cardiac  diseases,
but the extent of application  of several is limited due to distortions  arising
from the heart's  motion as it beats at a frequency  greater  than the  scanning
speed of these systems.  This is not the case for Imatron's Ultrafast CT. One of
the  significant  benefits of the fast scanning speed is the ability to "freeze"
the motion of the beating heart  allowing it to image and quantify small calcium
deposits in the  coronary  arteries,  resulting in sharp,  motion  artifact-free
images. This procedure is known as the coronary artery scan ("CAS").

Cardiovascular  disease is the  number  one cause of death in the United  States
accounting  for more than 950,000  deaths  annually.  Of these deaths,  coronary
heart  disease  contributes  to  approximately   500,000  deaths  annually.   Of
particular  importance is the fact that in approximately 150,000 cases annually,

<PAGE>

the first,  last and only  symptom of  coronary  heart  disease is a fatal heart
attack.  The Company  believes that this widespread  incidence of coronary heart
disease  in the  United  States,  coupled  with the fact that a large  number of
asymptomatic  individuals  experience heart attacks each year, indicates a clear
need for a safe and effective screening test for the earliest stages of coronary
heart disease.

The correlation between calcium in the coronary arteries,  atherosclerosis,  and
myocardial  infarction  (heart  attack) has been known since the 1950's.  In the
mid-1960's,  selective  coronary  angiography  was  introduced  and soon  became
routine.  Since that time coronary angiography,  which demonstrated narrowing or
occlusion of the coronary arteries,  has become the "gold standard" for positive
identification  of coronary  artery  disease.  Abnormal  results from  screening
tests,  such as exercise  electrocardiography  (ECG) and thallium stress nuclear
medicine are commonly  used as an  indication  for coronary  angiography.  These
tests produce a significant  percentage of false  abnormal  results such that as
many as twenty-five to thirty-five percent of the coronary angiograms  conducted
are deemed to be normal.  The importance of this high level of so-called  normal
angiograms is that coronary angiography is both expensive and invasive, exposing
the patient to some risk of  morbidity or even death.  In  addition,  statistics
indicate that some patients die suddenly after  receiving a "normal"  stress ECG
study and are then found upon autopsy to have had  significant  coronary  artery
disease.  The  Company  believes  these  statistics  illustrate  the  inadequate
predictive value of the standard,  noninvasive  screening tests used to diagnose
coronary artery disease.

The Company further believes that research demonstrates CAS has the potential to
accurately  identify  those  people who are  developing  early  coronary  artery
disease.  CAS can then serve as a feedback mechanism to monitor the treatment of
those with early  coronary  artery  disease,  a disease  which  recent  research
indicates that treatment may slow, stop or even regress. Until now, the only way
to directly  determine the effect of life-style  modification and lipid-lowering
pharmacologic  treatment  on coronary  artery  disease  was to perform  repeated
invasive coronary angiography.

For  those  patients  in whom CAS  detects  advanced  coronary  artery  disease,
intervention  may help prevent a crippling heart attack or sudden death. The CAS
test  also has great  potential  for  reducing  the  costs  associated  with the
unnecessary  treatment of those who have coronary risk factors, but show no sign
of coronary artery  disease.  It is estimated  thirty to thirty-five  percent of
people with elevated  cholesterol levels do not develop coronary artery disease.
Since there has not been, until the advent of the Ultrafast CT scanner, a method
to find those who are  beginning to develop  coronary  disease,  everyone with a
high  cholesterol  reading is treated as if they will develop the  disease.  The
Company believes that CAS is a powerful and  cost-effective  method of detecting
or ruling out coronary artery disease and represents a unique market. Currently,
only the Ultrafast CT scanner can provide the necessary technological capability
to  address  these  clinical  application   requirements.   Notwithstanding  the
foregoing,  CAS to date has not been broadly accepted as a method of identifying
coronary artery disease and there is no assurance that a significant market will
develop for this procedure.

Imatron  believes  that  possible  factors  affecting the demand for CT products
include,  among others,  potential  customers' budgetary  constraints  including
those imposed by government regulation, changes in the reimbursement policies of
the  government  and  third  party  insurers,  replacement  of older  equipment,
advancements in technology, and the introduction of new medical procedures.

SERVICE

The Company and its distributors  provide  installation,  customer service,  and
warranty service to their respective Ultrafast CT customers.  Imatron provides a
warranty to its  distributors on parts only during the 12 month period following
installation and warrants replacement parts for 90 days.

The Company  maintains a staff of technical  support engineers who are available
on a contract basis to assist its  distributors  during  installations or during
emergencies. The Company also sells spare parts to its distributors.

CORONARY ARTERY SCANNING - HEARTSCAN IMAGING, INC.

In 1993,  the  Company  organized  HeartScan  Imaging,  Inc.  as a  wholly-owned
subsidiary.  During  that year,  HeartScan  opened a CAS pilot  facility  at the
Company's  headquarters  in  South  San  Francisco,  California.  The  principal
purposes of the  facility  are to test market a variety of consumer  advertising
and  professional  education  programs,   test  software  developments  for  the
Company's scanner products and serve as a corporate  demonstration  site for the
Company's products and services.

HeartScan is also engaged in the business of developing  coronary artery disease
("CAD") risk assessment  centers and has developed a business and financing plan
for a nationwide  network of  Company-owned  and  operated  CAD risk  assessment
centers.  The  services  of such  centers  are  being  marketed  to  physicians,
insurers,  employers and directly to the public.  As of December 31, 1996,  five
CAD risk  assessment  centers were owned and operated by HeartScan.  HeartScan's
near-term  business  strategy  involves the  development of five to six Coronary
Artery  Disease  Risk  Assessment  Centers  over  the  next  twelve  months  and
additional centers thereafter. There is no assurance that HeartScan will be able
to complete  the  centers  provided  for in its  business  plan.  The success of
HeartScan's  Coronary Artery Disease Risk Assessment Centers depends on a number
of factors  including,  but not limited to,  HeartScan's  ability to: obtain and
operate in compliance  with  appropriate  licensing from  applicable  regulatory
authorities;  develop working  relationships with local groups of cardiologists;
educate patients, referring physicians and third-party payors about the benefits
of the CAS and HeartScan's  centers;  and successfully  manage the operations of
the centers.  HeartScan anticipates negative cash flow and substantial operating
losses during the next several years of its operations and there is no certainty
that HeartScan can operate profitably.

In June, 1996, Imatron completed a private offering whereby Imatron sold 100,000
shares of HeartScan  Series A preferred stock to  unaffiliated  third parties at
$160.00 per share with realized proceeds of $14,798,000 (net of offering costs).
The sale of such shares,  together with the exercise of certain  incentive stock
options  by  members of the  HeartScan  and  Imatron  management  team,  reduced
Imatron's ownership in HeartScan to 49.5% as of December 31, 1996. The HeartScan
Series A Preferred  Stock may be exchanged at the sole option of the holder into
Imatron  common stock at an exchange  price of $5.00 per share until the earlier
of a) two year period following closing of the Preferred Stock offering; or b) a
HeartScan initial public offering. If there is no initial public offering within
24 months of the  Preferred  Stock  closing,  holders may convert the  HeartScan
Series A Preferred  Stock into Imatron common stock at a conversion  price equal
to the greater of $1.50 per share or a 27% discount  from the  weighted  average
closing  price  of  Imatron  common  stock  for  the 90 day  period  immediately
preceding  24  months of the  Preferred  Stock  closing  and each date that is 3
months  thereafter  to and  including  the  48th  month of the  Preferred  Stock
closing.

HeartScan  believes the net proceeds  from the private  offering,  together with
lease and debt financing, will enable it to open five to six additional Coronary
Artery Disease Risk Assessment

<PAGE>

Centers over the next twelve months. In addition, a portion of the funds will be
used to develop a program to heighten public  awareness of the value of coronary
artery  scanning  and support and expand  collaborative  research to develop and
further refine  potential new tests that could be offered at HeartScan  centers.
To satisfy HeartScan's future capital and operating requirements and to complete
its business plan,  additional financing may be required.  There is no certainty
that HeartScan will, in the future, be able to sell its securities  privately or
in a  registered  public  offering.  If  additional  future  public  or  private
financing  is required by  HeartScan,  Imatron  may  experience  dilution of its
current ownership position in HeartScan, along with other holders of HeartScan's
securities.  If such financing cannot be obtained,  HeartScan may not be able to
complete its business  plan and may seek to sell some or all of its assets or to
merge with another company.

HeartScan is dependent on Imatron for the scanners  used in its Coronary  Artery
Disease Risk Assessment Centers.  HeartScan does not believe there are any other
machines which can accomplish the same tests. In the event that Imatron, for any
reason, should cease manufacturing such equipment,  HeartScan would be unable to
complete its business plan.

HeartScan's  competitors  are clinics and  hospitals  using either  Ultrafast CT
scanners or conventional CT scanners for coronary artery screening.  In order to
compete successfully  against these competitors,  it must develop a good working
relationship  with  cardiologists  and educate  the public and health  insurance
companies  about the  benefits of  coronary  artery  screening  tests as well as
significant advantages over other testing modalities in terms of accuracy, cost,
time and degree of invasiveness.

HeartScan's  near-term  plans for  opening new  clinics  will place  significant
strain on its administrative,  operational and financial resources and increased
demands on its  systems  and  controls.  If its  management  is unable to manage
growth effectively, HeartScan's operating results could be adversely effected.

RESEARCH AND DEVELOPMENT CONTRACTS

In March 1991, the Company  entered into an agreement  with Siemens  Corporation
("Siemens")  which included a Development  Agreement.  (see  "Transactions  With
Siemens Corporation" below). Pursuant to the Development Agreement,  the Company
and Siemens  pursued the joint  development of certain EBT  technology  products
funded  by  Siemens.  Upon  successful  conclusion  of the  development  of such
products,  Siemens had the sole right to manufacture  the products.  The Company
recognized  $0,  $1,753,000  and  $5,013,000 of revenue  under this  Development
Agreement in 1996, 1995 and 1994, respectively.

On March 31, 1995,  the Company and Siemens  entered into a new  agreement  (the
"Memorandum of Understanding") pursuant to which the parties agreed to terminate
the  existing   Development   Agreement  and  substitute  in  its  place  a  new
collaborative   research  agreement.   Under  the  new  collaborative   research
agreement,  the parties will jointly  conduct  research and  development  over a
three year period directed toward certain  improvements  and enhancements to the
Company's  C-150 product.  Siemens agreed to fund an aggregate of $15 million of
Imatron-managed research and development for a three year period beginning April
1, 1995,  subject  to  addressing  mutually  agreed  upon goals and  objectives.
Pursuant to the funding, Imatron will contribute a portion equal to no less than
fifty percent of Siemens'  contribution  for the sole purpose of conducting  the
collaborative  research.  The  primary  goals of the  research  and  development
program are to develop and enhance the Ultrafast CT scanner system  performance,
increase product  reliability,  reduce  manufacturing  costs, and improve system
upgradability.  The results of the collaborative  research will be jointly owned
by the  parties  and  cross-licensed.  The  Company  recognized  $5,000,000  and
$3,884,000  of  revenue  under  the  collaborative  agreement  in 1996 and 1995,
respectively.

                                    MARKETING

The  Company's  Ultrafast  CT scanners  are  utilized by a variety of  customers
including  large  teaching and research  hospitals,  medium-size  hospitals  and
imaging clinics.

<PAGE>

The Company  sells its Ultrafast CT product  directly and through  distributors.
The Company has, or had, the following distribution arrangements:

UNITED STATES, CANADA, AND EUROPE

In April 1995,  pursuant to the Memorandum of  Understanding  above, the Company
entered into an agreement  with Siemens  giving  Siemens the exclusive  right to
distribute the Company's C-150 scanner in the United States,  Canada, Europe and
India. (see "Transactions With Siemens  Corporation"  below).  Siemens purchased
two, one, and six C-150 scanners in 1996, 1995 and 1994, respectively.

JAPAN

Beginning in 1986,  Mitsui & Co., Ltd.  ("Mitsui")  was the  distributor  of the
Company's   products  in  Japan,   either  directly  or  through  a  third-party
distributor.  On December 10, 1993  Imatron  entered  into two  agreements  with
Mitsui that became  effective in January 1994; the Settlement  Agreement and the
Transition Agreement. Pursuant to these agreements, Mitsui agreed to pay Imatron
$1.5 million in  consideration  of Imatron's  agreement to relieve Mitsui of its
obligation to purchase  additional  Ultrafast CT scanners from Imatron.  Imatron
agreed to purchase  certain  Ultrafast CT scanner  inventory  from Mitsui and to
undertake  all service and  warranty  responsiblitiy  for  Ultrafast CT scanners
installed in Japan.  Imatron further agreed to complete  certain sales contracts
currently in place between Mitsui and various end users in Japan.

On January 7, 1994,  Imatron  entered into a Joint Company  Agreement  with Tobu
Land System  Company  and Kino  Corporation  pursuant  to which a joint  venture
company  was  established  to  market,  sell,  install  and  service  Imatron CT
scanners.  The joint venture was designated as Imatron Japan,  Inc. and is owned
51% by Tobu Land System  Company,  25% by Kino  Corporation  and 24% by Imatron.
Imatron did not assume any financial  funding  requirements  associated with the
formation of Imatron Japan, Inc. The Company's investment in Imatron Japan, Inc.
is  carried at no value in the  accompanying  financial  statements.  Imatron is
under no  obligation  to fund the  operations  of  Imatron  Japan,  Inc.  and is
prepared to abandon its interest.

On  February  3,  1994,   Imatron  and  Imatron  Japan,   Inc.  entered  into  a
Distributorship  Agreement  pursuant  to  which  Imatron  Japan,  Inc.  has been
appointed as Imatron's exclusive  Distributor in Japan.  Imatron has transferred
its rights and obligations  under the Transition  Agreement  between Imatron and
Mitsui & Co. Ltd. to Imatron Japan,  Inc.  Imatron Japan,  Inc. took delivery of
five,  five,  and six C-150  Ultrafast CT scanner  systems from Imatron in 1996,
1995 and 1994, respectively.  Imatron Japan, Inc. also purchased two refurbished
Ultrafast CT systems in 1995. In connection  with these sales,  the Company pays
$130,000 in commissions for each new C-150 Ultrafast CT scanner sold to Imatron,
Japan Inc.

Imatron Japan,  Inc. has ordered 10 additional  Ultrafast CT scanner systems for
delivery in 1997 and 1998 with an option to purchase three additional systems in
the years 1997 and 1998, respectively.

RELIANCE ON DISTRIBUTORS

A  substantial  portion of the  Company's  sales of its scanners is done through
distributors. There is no assurance that the Company's distibutors will actually
meet their contractual  minimums on a timely basis.  Failure by the distributors
to meet their  obligations  could adversely affect the Company's  operations and
financial position.

<PAGE>

SALES INFORMATION

The end user list price for the  Ultrafast  CT scanner  varies  depending on the
configuration  and  country to which the  scanner is  shipped.  The sales  price
includes   installation   by  field   service   personnel,   system   check  and
certification,  customer  training in the scanner's use, and a limited  12-month
parts warranty.  In addition,  local taxes and import duties may be added.  This
price, which is significantly higher than that of conventional CT scanners,  may
serve to limit sales of the  Company's  scanner to larger  hospitals and medical
imaging  clinics that are able to generate a higher than average  patient  usage
volume to offset its higher cost.

Unit export sales for fiscal years ended December 31 are as follows:

                                        1996              1995             1994

                      TRANSACTIONS WITH SIEMENS CORPORATION

In  March  1991,  the  Company  entered  into a  Basic  Agreement  with  Siemens
Corporation  ("Siemens") which consisted of four separate sub-agreements each of
which has been subsequently modified in various respects by the parties.

On March 31,  1995,  the Company  and Siemens  entered  into an  agreement  (the
"Memorandum of  Understanding"  or "MOU") pursuant to which the  relationship of
the  parties  as   established   by  the  Basic   Agreement  was   substantially
restructured.  Pursuant to the MOU, the  sub-agreements  of the Basic  Agreement
were terminated and a number of new  relationships  were created.  First, the $4
million term loan was canceled in exchange for the transfer to Siemens of all of
Imatron's interest in five patents subject to a royalty-bearing  license back to
Imatron and the cancellation of the minimum  purchase  provision of the previous
distribution agreement. Second, the parties agreed to terminate, as of March 31,
1995,  the existing  Development  Agreement  and  substitute  in its place a new
collaborative  research  agreement  pursuant to which the parties  will  jointly
conduct  research  and  development  over a three year  period  directed  toward
certain  improvements and enhancements to the Company's C-150 product  described
above.  Third,  Siemens was appointed  Imatron's  exclusive  distributor for the
company's C-150 Ultrafast scanner in the United States, Canada, Europe and India
for a three  year  period  effective  April 1, 1995 and ending  March 31,  1998.
Imatron retains exclusive  distribution rights in the rest of the world. Fourth,
the Company and Siemens granted  reciprocal  licenses to each other covering the
electron beam  technology  presently used (and to be developed)  relating to the
design and manufacture of electron beam products.

Pursuant to the new collaborative research agreement, Siemens has agreed to fund
a maximum aggregate of $15 million of  Imatron-managed  research and development
over the three years,  subject to addressing  certain mutually agreed upon goals
and objectives. Pursuant to the funding, Imatron will contribute a portion equal
to no less than fifty percent of Siemens'  contribution  for the sole purpose of
conducting  the  collaborative  research.  The primary goals of the research and
development program are to develop enhanced system performance, increase product
reliability,  reduce manufacturing costs, and improve system upgradability.  The
results of the  collaborative  research will be jointly owned by the parties and
cross-licensed.

Siemens has agreed to use its best efforts to  distribute  the  Company's  C-150
product in its exclusive markets subject to no minimum purchase obligations. The
term of the Distribution  Agreement may be extended for an additional three year
period,  upon mutual  agreement  by Imatron and  Siemens.  Any  extension of the

<PAGE>

agreement is subject to agreement on minimum purchase commitments and price.

Pursuant to the cross licensing agreement, Siemens has granted Imatron a license
to: (a) all of the research results from the prior  development  agreement;  (b)
the patents transferred by Imatron to Siemens; and (c) Siemens' rights under the
new collaborative  research agreement.  Imatron has granted a license to Siemens
in the  field  of  medical  imaging  to:  (a)  Imatron's  rights  under  the new
collaborative  research  agreement;  and (b) Imatron's electron beam technology.
Pursuant  to the  license,  Imatron has agreed not to grant to any third party a
license in the field of  medical  imaging  during  the term of the  Distribution
Agreement  and the  collaborative  research  agreement and for a period of three
years thereafter.  Siemens may not use Imatron's technology to manufacture C-150
scanners until Imatron has delivered to Siemens 50 such units in any year, or in
the event  Imatron is unable to perform  its  obligations  to Siemens  under the
Distribution Agreement.


                           INVISION TECHNOLOGIES, INC.

In 1990, the Company established a joint venture company, InVision Technologies,
Inc.  ("InVision")(formerly  Imatron Industrial Products,  Inc.), with FI.M.A.I.
Holding  S.A.  ("FI.M.A.I."),  a former  shareholder  of  Imatron,  to  develop,
manufacture,  market and support  advanced CT technology in the baggage,  parcel
and freight scanning market. Upon organization,  Imatron  contributed  $250,000,
certain  parts,  components  and material and entered into a Technology  License
Agreement.

The Technology  License Agreement between the Company,  FI.M.A.I.  and InVision,
grants InVision an exclusive, worldwide, perpetual and fully-paid license to use
the Company's technology and patents for the development,  manufacture, use, and
sale of compact medical scanner  products for military field  applications,  and
mail, freight, parcel or baggage scanner products.  Also, InVision has agreed to
grant back to Imatron an exclusive,  worldwide,  perpetual and fully-paid  right
and license to use InVision's technology and patents outside of InVision's field
of use.

In July 1996,  Imatron  sold its  remaining  shares of  InVision  common  stock.
InVision  common  stock was  carried  at no cost by  Imatron.  Imatron  realized
$1,756,000 from the InVision common stock sale. The gain on sale was recorded as
other income in the Company's  consolidated  financial  statements  for the year
ended December 31, 1996.

As of December 31, 1996, Imatron has no ownership interest in InVision.

                                   COMPETITION

In  the  non-cardiac  imaging  applications  market  (comprised  principally  of
hospital radiology  departments),  the Company's  principal  competition is from
current  manufacturers of conventional CT scanners,  including  General Electric
Company,  Siemens  Corporation,  Elscint,  Picker  International,  Inc., Philips
Medical  Systems  and  Toshiba  Medical  Corporation  and  others.  Non-invasive
diagnostic imaging techniques such as ultrasound,  radioisotope imaging, digital
subtraction  angiography  and  magnetic  resonance  imaging  are also  partially
competitive with the Company's  scanners.  Each of the companies named above, as
well as ATL, Accuson and ADAC Laboratories,  markets equipment using one or more
of these techniques. All of these companies have greater financial resources and
larger  staffs than those of the Company and their  products are, in most cases,
substantially less expensive than the Ultrafast CT scanner.

<PAGE>

The  Company  believes  that in  order to  compete  successfully  against  these
competitors,  it must continue to  demonstrate  that the Ultrafast CT scanner is
both an acceptable  substitute for conventional CT scanners in scanning areas of
the body where motion is not a limitation and a valuable cardiac diagnostic tool
capable of producing unique and useful images of the heart. Although the Company
believes that the Ultrafast CT can produce images of a quality and resolution as
good as, or superior to, images  produced by "state of the art"  conventional CT
scanners,  it lacks certain features that many competing premium scanners offer.
These  include  lack of a  high-resolution  mode.  There  is no  certainty  that
potential purchasers will accept the Company's scanner without such features.

Also,  the Company  believes that  customers and  potential  customers  expect a
continuing  development  effort to improve the functionality and features of the
scanner.  The Company  continually  seeks to develop  product  enhancements  and
improve product reliability.  Imatron's future success may depend on its ability
to  complete  certain  product  enhancement  and  product  reliability  projects
currently  in  progress,  as well as on its  continued  ability to  develop  new
products  or  product  enhancements  in  response  to new  products  that may be
introduced by other  companies.  There can be no assurance  that Imatron will be
able to continue to improve product  reliability or introduce new product models
or product enhancements as required to remain competitive.

Other factors,  in addition to those described above, that a potential purchaser
might  consider in the  decision to replace a  conventional  CT scanner  with an
Ultrafast  CT scanner  include  purchase  price,  patient  throughput  capacity,
anticipated  operating  expenses,  estimated useful life and post-sale  customer
service and support.  The Company  believes that its scanner is competitive with
respect to each of these factors.


                                  MANUFACTURING

The  Company  manufactures  its scanner at its South San  Francisco,  California
headquarters  facility.  To date, the typical  manufacturing  cycle has required
approximately six months from the authorization of manufacturing to the delivery
of a scanner.

Many  of the  components  and  sub-assemblies  used  in the  scanner  have  been
developed  and  designed  by  Imatron  to  its  custom  specifications  and  are
obtainable  from limited or single sources of supply.  In view of the customized
nature of many of these  components  and  sub-assemblies,  there may be extended
delays between their order and delivery. Delays in such delivery could adversely
affect Imatron's present and future production  schedules.  The Company has made
and continues to make inventory investments to acquire long lead time components
and  sub-assemblies  to minimize the impact of such delays. In recent years, the
Company has developed  alternative sources for many of its scanner subcomponents
and continues its programs to qualify vendors for the remaining critical parts.

Also,  certain vendors currently require  cash-on-delivery  or prepayment terms.
There can be no  assurance  that such  actions  will not  adversely  affect  the
Company's  production  schedule and its ability to deliver  products in a timely
manner. As a result of certain vendors currently  requiring  cash-on-delivery or
prepayment  terms,  the Company must  maintain  higher  levels of cash and other
sources of credit to fund material purchases than otherwise would be required.

                              GOVERNMENT REGULATION

Amendments to the Federal Food, Drug, and Cosmetic Act ("Amendments") enacted in
1976, and regulations issued or authorized thereunder, provide for regulation by
the Federal Food and Drug Administration ("FDA") of the marketing,  manufacture,
labeling,  packaging,  sale and distribution of "medical devices," including the
Company's scanner.  Among these regulations are requirements that medical device
manufacturers register their manufacturing facilities with the FDA, list devices
manufactured  by them,  file  various  reports  and comply with  specified  Good
Manufacturing   Practice  (GMP)   regulations.   The  FDA  enforces   additional
regulations  regarding the safety of equipment  utilizing  x-rays,  including CT
scanners. Various states also impose similar regulations.

The Amendments also impose certain  requirements  which must be met prior to the
initial  marketing of medical  devices  introduced  into commerce  after May 28,
1976.  Other  requirements  imposed on medical  device  manufacturers  include a
pre-market  notification  process  commonly  known as the 510(k)  application to
market a new or modified  medical device.  Additionally,  and  specifically,  if
required by the FDA, a pre-market  approval (PMA) may be required.  This process
is  potentially  expensive  and time  consuming  and must be completed  prior to
marketing a new medical device. The Company has received appropriate  clearances
from the FDA to  market  both the  C-100 and C-150  Ultrafast  CT  scanner.  The
Company  believes that it is presently in  substantial  compliance  with the GMP
requirements and other regulatory issues promulgated by the FDA.

The FDA also regulates the safety and efficacy of radiological devices. Although
the Company believes it is in compliance with all applicable radiological health
regulations established by the FDA, there can be no assurance that the Ultrafast
CT scanner will continue to comply with all such standards and regulations  that
may be pronounced.  In any event,  compliance with all such  requirements can be
costly and time consuming,  with a resultant  materially adverse effect upon the
development of the Company's business and its future profitability.

FDA clearance to market does not guarantee or imply reimbursement by third-party
payors such as  Medicare,  Medicaid,  Blue  Cross/Blue  Shield or other  private
health  insurers.  Medicare  and  Medicaid  reimburse  for  procedures  that are
generally accepted or that have been proven safe and effective.  The Health Care
Financing  Administration ("HCFA"), which oversees Medicare and Medicaid payment
policies,  will not authorize  payment for procedures which are considered to be
experimental.  HCFA has determined that diagnostic  examinations of the head and
other parts of the body  performed by CT scanners are covered if the  contractor
who  administers  the local  Medicare  program finds that medical and scientific
literature  and opinion  support the effective use of a scan for the  particular
condition.

The Federal government and certain states have enacted cost-containment measures
such as the  establishment  of maximum fee  standards in an attempt to limit the
extent and cost of  governmental  reimbursement  of allowable  medical  expenses
under Medicare,  Medicaid and similar governmental  programs. A number of states
have  adopted,  or are  considering  the  adoption,  of similar  measures.  Such
limitations  have led to a reduction in, and may further  limit funds  available
for, the purchase of diagnostic  equipment such as the Company's  scanner and in
the number of  diagnostic  imaging  procedures  performed in hospitals and other
medical institutions such as HeartScan's imaging clinics.

Certain  states have adopted  requirements  that hospitals and other health care
facilities,  such as imaging  clinics,  obtain a Certificate of Need ("CON") for
major  capital  expenditures,  in the  absence  of  which  they  will be  denied
reimbursement for services and funding relating to such capital expenditures.  A
number of states have enacted more stringent CON  legislation  such as requiring
private physicians to obtain a CON for any CT scanner, regardless of cost. There
can be no assurance  that Imatron's  potential  customers will be able to secure
<PAGE>

CON's or will be willing to pursue the application procedure.

The Company's primary customers operate in the healthcare  industry.  The health
care  industry  is highly  regulated.  Both  existing  and  future  governmental
regulations  could  adversely  impact the market for the Company's  Ultrafast CT
scanner and the Company's business. The Company's operations are also subject to
regulation by other federal,  state and local governmental entities empowered to
enforce  pertinent  statutes  and  regulations,  such as those  enforced  by the
Occupational  Safety and Health Agency and the Environmental  Protection Agency.
In some  cases,  state or local  regulations  may be stricter  than  regulations
imposed by the federal  government.  The Company was most recently  inspected by
the  State  of  California,   Department  of  Occupational   Safety  and  Health
Administration  in November 1993.  Minor  violations were issued by Cal/OSHA and
were immediately  corrected by the Company.  The subsequent follow up inspection
in December 1993, by the same  regulatory  body,  yielded  satisfactory  results
without the issuance of further notice of violation.  The Company  believes that
it is in substantial  compliance with California  regulations  applicable to its
business.  In November 1996 and again in January 1997, the FDA conducted routine
inspections of Imatron's  manufacturing  operations.  Both inspections concluded
without Notices of Observations. Imatron frequently provides field modifications
or updates of components and software to operational sites.  Imatron voluntarily
advised  FDA during  these  inspections  that  certain  field  corrections  were
ongoing.  FDA concurred with Imatron's  decision to field upgrade  certain sites
and assigned recall numbers Z-304/307-7 and Z-298/299-7.  Imatron is required to
notify the FDA  periodically  of the status of these  corrections and again upon
completion.  Imatron is complying with these requests and expects  correction to
the  above  recall  numbers  by May 31,  1997.  Imatron  believes  that it is in
substantial compliance with the regulations promulgated by the FDA.

HeartScan's  activities are subject to extensive regulation,  generally by state
and  local  governmental   entities.   Although  HeartScan  believes  it  is  in
substantial  compliance with all applicable  radiological  health  standards and
regulations, there can be no assurance that its business will continue to comply
with all such standards and regulations  that may be promulgated.  In any event,
compliance with all such  requirements can be costly and time consuming,  with a
resultant materially adverse effect upon the development of HeartScan's business
and its  future  profitability.  HeartScan's  operations  are  also  subject  to
regulation by other federal,  state and local governmental entities empowered to
enforce  pertinent  statutes  and  regulations,  such as those  enforced  by the
Federal   Food  and  Drug   Administration,   Occupational   Safety  and  Health
Administration and the Environmental  Protection Agency. Changes in governmental
regulations or new  regulations  adopted in the future may materially  adversely
affect  Imatron's  business.  In some cases,  state or local  regulations may be
stricter than regulations imposed by the Federal government.


                              PATENTS AND LICENSES

Imatron relies heavily on  proprietary  technology  which it attempts to protect
through patents and trade secrets.

In February  1981,  the Company was granted the exclusive use for five years and
non-exclusive use thereafter of certain technology and a patent pending owned by
the  University  of  California  ("UC")  under the terms of a license  agreement
between  UC  and  Emersub,  a  wholly-owned  subsidiary  of a  former  principal
shareholder  of the Company,  and a  sublicense  agreement  between  Emersub and
Imatron Associates (the predecessor to the Company), respectively. In June 1986,
the license  and  sublicense  agreements  were  amended to extend the  Company's
exclusive use of the technology through the remaining 13-year life of the patent
in exchange for modified  minimum  annual royalty  payments.  Under the terms of
Emersub's  license with UC,  Emersub was  obligated  to make certain  additional
payments in connection with the license. In October 1990, pursuant to subsequent
amendments  of the  license and  sublicense  agreements  the  Company  issued an
aggregate  of 132,813  shares of Series A  Preferred  Stock to UC and Emersub in
satisfaction of this  obligation.  The University of California  converted their
125,000  Series A Preferred  Stock into  625,000  common  stock  shares in 1993.
Emersub  converted their 7,813 Series A Preferred Stock into 39,065 common stock
shares in September 1995.

Under the continuing sublicense  agreement,  as amended, the Company is required
to pay annual  royalties  to Emersub  equal to 2.125% of net sales of certain of
the Company's  products.  The Company's  Chairman of the Board,  Dr.  Douglas P.
Boyd, receives 6% of all of the royalties paid by Emersub to UC. Loss by Imatron
of its rights under the patent as a result of termination of its sublicense from
Emersub,  or the underlying  license,  could have a material adverse effect upon
Imatron's  business and future  prospects.  There are no present  disputes  with
either UC or Emersub.

Development  of  portions  of  the  technology  covered  by the  UC  patent  and
sublicensed  to Imatron has been funded in  substantial  part  through  research
financing made available to UC by the National Institutes of Health. As a result
of such  financing,  it is possible that the U.S.  Government may assert certain

<PAGE>

claims in such UC patents,  including  the right to a  royalty-free  license for
governmental use.

In addition,  Imatron holds  twenty-four  U.S.  Patents of its own (each with a
remaining  life  in  excess  of  3  years)  and  has  filed  three  U.S.  patent
applications  covering  various  integral  components of the scanner  including,
among others,  its electron  beam assembly and its x-ray  detector and has filed
applications  corresponding  to several of these  patents  and  applications  in
various European Patent Convention countries,  Canada and Japan. There can be no
assurance that any such  applications will result in the issuance of a patent to
the Company.  Imatron's patents and patent  applications have not been tested in
litigation and no assurance can be given that patent  protection  will be upheld
or will be as extensive as claimed. Furthermore, no assurance can be given as to
the Company's ability to finance  litigation  against parties which may infringe
upon  such  patents  or  parties  which  may claim  that the  Company's  scanner
infringes upon their patents.  However,  the agreement signed by the Company and
Siemens Corporation in March 1991 allows Siemens Corporation to enter litigation
in favor of Imatron.

On March 31, 1995, the Company and Siemens Corporation (Siemens) entered into an
agreement (the "Memorandum of Understanding") relating in part to certain of the
Company's patents (see  "Transactions  With Siemens  Corporation" ). Pursuant to
the agreement,  the Company  transferred  to Siemens five patents,  two of which
cover features of the Company's C-150 scanner,  in partial  consideration of the
cancellation  by Siemens of the $4 million term loan to the Company.  As part of
the  agreement  Siemens  granted to the  Company a  non-exclusive,  irrevocable,
perpetual  license to the five  patents.  The license is subject to a royalty of
$20,000  for  each  new  C-150  unit  sold by the  Company  beginning  with  the
twenty-first C-150 unit produced in any year.

In September 1995,  Siemens  asserted a claim against the Company  regarding the
lapse of certain foreign registrations of one of the patents assigned to Siemens
by the  Company in  connection  with the March 31,  1995  agreement  between the
companies. The technology involved in the patent is not used presently in any of
the Company's products.  The Company  substituted a patent,  subject to existing
license-back,  currently used in its  technology for the previously  transferred
patent. Representatives of Siemens have agreed with the Company to these terms.


In the event some or all of the Company's patent  applications are denied and/or
some or all of its patents held  invalid,  the Company  would be prevented  from
precluding its competitors from using the protected technology set forth in such
patent   applications  or  patents.   Because  the  Company's  products  involve
confidential  proprietary  technology and know-how, the Company does not believe
such a loss of patent  rights  would have a  material  adverse  effect  upon the
Company.

The Company also believes that many of its proprietary  technologies  are better
protected as trade secrets or  copyrights  than by patents.  Moreover,  although
protection  of the Company's  existing  proprietary  technologies  is important,
other  factors  such as product  development,  customer  support  and  marketing
ability are also important to the development of the Company's business.


                                    EMPLOYEES

As of February 1, 1997, the Company had 170 employees, including 30 employees in
service,  8 in  sales/marketing,  62  scientists  and  engineers in research and
development,  53  employees  in  manufacturing,  and 17 employees in finance and
administration.   HeartScan  had  37   employees,   including  26  employees  in
operations,   7  in  sales  and   marketing   and  4  employees   in   corporate
administration.  None of the employees are  represented  by a labor union and no
work stoppages or strikes have occurred. The Company believes that it has good

<PAGE>

labor relations with its employees.

                                 CERTAIN FACTORS

In evaluating  the Company and its business,  the  following  factors  should be
given careful consideration,  in addition to the information mentioned elsewhere
in this Form 10-K:

OPERATING HISTORY

Imatron was incorporated in February 1983, and incurred losses each quarter from
inception through December 31, 1990. Its first recorded  profitable year was the
year ended December 31, 1991 during which a $4,000,000 payment for the licensing
of  technology  to  Siemens  Corporation  was  received.  The  Company  incurred
additional net losses in both 1993 and 1992. In 1994,  the Company  incurred its
first year of net income  from  operations  amounting  to  $3,221,000  partially
offset by $911,000 of net losses  incurred by HeartScan.  In 1996 and 1995,  the
Company incurred net losses of $10,465,000 and $2,449,000, respectively. The net
losses are  partially a result of the  operating  losses  incurred by  HeartScan
which  amounted to $4,573,000  and  $2,132,000  in 1996 and 1995,  respectively.
There is no assurance  that Imatron can return to  profitable  operations in the
future.

In the  past,  Imatron  has  funded  its  losses  primarily  though  the sale of
securities in two public offerings and a number of private  placements,  through
the exercise of options and warrants,  through the 1991 license for medical uses
of its electron-beam  technology to Siemens  Corporation,  and through revolving
lines of credit.  In 1995, the Company raised $9,882,000 (net of offering costs)
in two offerings of Common Stock to certain  institutional  investors.  In 1996,
the Company received  $16,672,000 through the sale of shares of Common Stock and
the  exercise  of warrants  and stock  options  for shares of common  stock.  In
addition,   HeartScan  raised  $14,798,000  (net  of  offering  costs)  for  use
exclusively to develop its operations.  As of December 31, 1996, the Company has
a  consolidated  accumulated  deficit of  $68,022,000.  As of December 31, 1996,
HeartScan has an accumulated deficit of $8,600,000.

Management  believes that cash,  cash  equivalents  and  short-term  investments
existing at December 31, 1996 and the  estimated  proceeds from ongoing sales of
products  and  services in 1996 will  provide the  Company  and  HeartScan  with
sufficient  cash for  operating  activities  and  capital  requirements  through
December 31, 1997.

NEED FOR ADDITIONAL FINANCING

To satisfy the Company's future capital and operating  requirements,  profitable
operations or additional public or private financing will be required. If future
public or private financing is required by the Company, holders of the Company's
securities may experience  dilution.  If such financing cannot be obtained,  the
Company may seek to sell or license  additional  portions of its technology,  to
sell some or all of its other assets or to merge with another company.

In addition,  HeartScan  may need  additional  financing to continue to fund its
plan to own and  operate  CAS  centers.  In the  event  HeartScan  can no longer
support its operating  expenses and is unable to raise  additional funds it will
have to curtail its center development and expansion activities.

MATERIAL DEPENDENCE UPON KEY PERSONNEL

The  Company  and  HeartScan  have been,  and will  continue  to be,  materially
dependent  upon  the  technical  expertise  of its  engineering  and  management
personnel. The loss of a

<PAGE>

significant number of such personnel would have a materially adverse effect upon
the  Company's  business  and future  prospects.  The Company  does not maintain
key-man life insurance.

HIGH COST OF SCANNER

The distributor  list price of Imatron's  Ultrafast CT scanner is  significantly
higher than that of commercially  available  conventional CT scanners and higher
than the price of "top-of-the-line"  scanners. Such pricing may limit the market
for Imatron's product.  Potential  customers' budgetary  limitations,  including
those imposed by government  regulation,  may often compel the purchase of lower
cost, conventional CT scanners.

LIMITED CLINICAL DEMONSTRATION OF CERTAIN ADVANTAGES OF THE COMPANY'S SCANNER

The Company's scanner has been used in a clinical  environment since April 1983.
Clinical  use of the C-100 XL scanner  model began in February  1989.  The C-150
Ultrafast  CT scanner  was first used in 1992.  Fifty-four  C-150  scanners  are
currently  installed in a clinical  setting.  The Company  believes  that market
acceptance of the Ultrafast CT scanner  continues to depend in substantial  part
upon the clinical demonstration of certain asserted technological advantages and
diagnostic capabilities. There is no assurance that these asserted technological
advantages  and  diagnostic  capabilities  will result in the  development  of a
significant  market for the  Ultrafast CT that will allow the Company to operate
profitably.

PRODUCT LIABILITY RISKS

As a manufacturer and marketer of medical diagnostic  equipment,  the Company is
subject to potential  product  liability  claims.  As a supplier of radiological
diagnostic  services,  HeartScan is also subject to potential  liability claims.
For example, the exposure of normal human tissue to x-rays, which is inherent in
the use of CT scanners for diagnostic imaging, may result in potential injury to
patients  subjecting  the  Company to  possible  liability  claims.  The Company
presently   maintains  primary  and  excess  product  liability  insurance  with
aggregate limits of $5.0 million per occurrence.  No assurance can be given that
the Company's product liability insurance coverage will continue to be available
or, if available, that it can be obtained in sufficient amounts or at reasonable
cost or that it will prove sufficient to pay any claims that may arise.

VOLATILITY OF STOCK PRICE

The  market  prices  for  securities  of  advanced  technology   companies  have
historically  been highly volatile,  including the market price of shares of the
Company's Common Stock. Future  announcements by the Company or its competitors,
including announcements concerning  technological  innovations or new commercial
products,  results  of  clinical  testing,  changes in  government  regulations,
regulatory  actions,  health care reform,  proprietary  rights,  litigation  and
public  concerns  as to the  safety  of  the  Company's  or  its  collaborators'
products, as well as period-to-period variances in financial results could cause
the market price of the Common Stock to  fluctuate  substantially.  In addition,
the stock market has experienced extreme price and volume fluctuations that have
particularly  affected the market price for many advanced  technology  companies
that have often been unrelated to the operating  performance of these companies.
These broad market  fluctuations  may  adversely  affect the market price of the
Company's Common Stock.

NO DIVIDENDS ON PREFERRED AND COMMON STOCK

The  Company  has not paid  dividends  on its  Preferred  or Common  Stock since
inception.   Even  if  its  future   operations   result  in   revenues   and/or

<PAGE>

profitability,  as to which  there  can be no  assurance,  there  is no  present
anticipation that dividends will be paid.  Rather,  the Company expects that any
future earnings will be applied toward the further  development of the Company's
business.

ITEM 7 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
              CONDITION AND RESULTS OF OPERATIONS

                         LIQUIDITY AND CAPITAL RESOURCES

At December 31, 1996, the Company had working capital of $33.0 million which was
a 131%  increase  compared to working  capital of $14.3  million at December 31,
1995. The current ratio increased to 4.4:1.0 from 2.4:1.0 at December 31, 1995.

The  Company's  assets  increased  in 1996 by 72% to $53.2  million  compared to
December  31,  1995 total  assets of $30.9  million  primarily  due to  proceeds
realized  of $31.7  million  (net of  offering  costs)  from  private  placement
offerings and exercises of warrants and stock options. In addition, property and
equipment  increased by $2.5 million exclusive of $2.7 million in additions that
are related to capitalized  leases.  Capital lease obligations were entered into
in  1996  principally  due to the  establishment  of two  new  HeartScan  clinic
scanners.  The deferred  income of $1.4 million is related to deferred profit on
sales of scanners under sale-leaseback arrangements.

In connection with the March 1995 Memorandum of Understanding with Siemens,  the
$4 million  note  payable to Siemens was  cancelled in exchange for five patents
and termination of the minimum purchase obligations.

<PAGE>

Management  believes that cash,  cash  equivalents  and  short-term  investments
existing at December 31, 1996 and the  estimated  proceeds from ongoing sales of
products and services in 1996 will provide the Company with  sufficient cash for
operating activities and capital requirements through December 31, 1997.

HeartScan  anticipates that 1997 capital  equipment  acquisitions  will increase
from 1996 due to the expansion of clinic base.

To satisfy  the  Company's  capital  and  operating  requirements  beyond  1997,
profitable  operations,  additional  public  and/or  private  financing  or  the
incurrence  of debt may be required.  If future  public or private  financing is
required by the Company,  holders of the  Company's  securities  may  experience
dilution.  There can be no assurance  that equity or debt sources,  if required,
will be available or, if available, will be on terms favorable to the Company or
its shareholders.

The Company does not believe  that  inflation  has had a material  effect on its
revenues or results of operations.

                              RESULTS OF OPERATIONS

1996 vs. 1995

Overall  revenues  decreased 3% from $26,700,000 in 1995 to $25,768,000 in 1996.
Product sales,  including $1.8 million under  sale-leaseback  arrangements  with
various  leasing  companies in both 1996 and 1995,  increased 6% due to a higher
option/upgrade  revenues.  There were 10 scanners and 1 refurbished unit sold in
1996 versus 10 scanners in 1995.  Service revenues decreased 37% from $5,529,000
in 1995 to  $3,465,000  in 1996  primarily  due to lower spare  parts  shipment.
Research  and  development  contract  revenues  decreased  by 11% to  $5,000,000
compared to  $5,637,000 in 1995 due to the lower  revenue  recognized  under the
Memorandum  of  Understanding  with Siemens as compared to the previous  Siemens
development agreement that was terminated in March 1995. Clinic revenues related
to the HeartScan  subsidiary increased by 181% to $1,293,000 in 1996 compared to
$460,000  in 1995  as a  result  of  additional  coronary  artery  disease  risk
assessment centers (clinics) operating in 1996.

The costs of  revenues  as a percent  of  revenues  for 1996 is higher at 96% as
compared  to 89% in 1995.  Product  cost of  revenues  as a percent  of  product
revenues increased to 90% in 1996 from 89% in 1995 as a result of lower realized
margin on  scanners  sold.  Service  cost of  revenues  as a percent  of service
revenues  increased  to 91% in 1996 as compared to 71% in 1995 due  primarily to
lower volume of spares shipped. Development contract revenue and cost of revenue
is  identical  in  1996  due to  the  terms  of the  three  year  Memorandum  of
Understanding  with  Siemens.  In 1995,  development  revenue  also  included  a
development  contract with Siemens  which  provided a higher gross margin to the
Company.  This  contract was  terminated  in 1995.  Clinic cost of revenues as a
percent of clinic revenues decreased to 173% in 1996 as compared to 293% in 1995
primarily  due  to  additional  revenues  related  to the  establishment  of new
Heartscan clinics.

Operating  expenses of $13,390,000 for 1996 increased by 45% as compared to 1995
expenses of $9,225,000.  Research and development expenses of $3,318,000 reflect
the research and  development  spending not covered by the Siemens  research and
development contract.  Marketing and sales expenses increased to $4,676,000 from
$3,137,000 in 1995  primarily  due to higher  advertising  expenses  incurred by
HeartScan and expenses related to studies conducted promoting the benefit of the
Company's product.  General and administrative  expenses increased to $5,396,000
from  $2,658,000 in 1995 mainly due to increases in bad debt expense  related to
Imatron  receivables and overhead  expenses related to the  establishment of new
HeartScan clinics.

<PAGE>

Other income  decreased to $2,508,000 from $4,021,000 in 1995 as a result of the
transaction recorded in 1995 eliminating the $4.0 million term loan with Siemens
in exchange for the transfer of five Imatron EBT patents and the cancellation of
Siemens' existing minimum purchase  obligations under the previous  distribution
agreement . In 1996, the Company recognized  $1,756,000 in other income from the
sale of 59,090 shares of Invision Technologies common stock.

Interest expense increased to $564,000 from $312,000 in 1995 due primarily to an
increase in capitalized scanners leased back by HeartScan.

1995 vs. 1994

Overall revenues  decreased 20% from $33,571,000 in 1994 to $26,700,000 in 1995.
Product sales,  including  $1,820,000 under the  sale-leaseback  arrangements in
1995,  decreased  35% due to decreased  scanner  shipments  which was  partially
offset by higher  option/upgrade  revenues.  Scanner  shipments  in 1995 were 10
units versus 16 units in 1994. Service revenues increased 16% from $4,750,000 in
1994 to  $5,529,000  in 1995  primarily  due to  higher  spare  parts  shipment.
Research and development  contract revenues went up by 5% to $5,637,000 compared
to $5,380,000 in 1994.  Clinic  revenues  increased by 99% due to an increase in
number of patient scans attributed to increased clinic advertisements.

Product  costs as a  percentage  of revenues was 89% in 1995 versus 71% in 1994.
This  increase  was the result of lower  realized  per unit revenue and overhead
expenses  being  allocated  to a smaller  number of units.  The cost of  service
revenues  as a  percentage  of revenues  decreased  to 71% in 1995 versus 85% in
1994. This decrease was the result of lower scanner  maintenance  costs. Cost of
clinic  revenues as a percentage of revenues went up to 293% as compared to 226%
in 1994  because  of  start-up  expenses  related  to the  establishment  of new
HeartScan clinics.

The cost of development  contracts as a percent of development contract revenues
decreased to 88% in 1995 versus 97% in 1994. The continued high level of cost is
due primarily to head count and associated costs required to continue activities
under the Siemens Collaborative Agreement.

Operating  expenses for 1995 increased by 38% as compared to 1994.  Research and
development  expenses are 63% higher in 1995  primarily due to the increased use
of  consultants.  Marketing  and sales  expenses were up 51% in 1995 versus 1994
primarily  because of commissions paid for scanners sold to Imatron Japan KK and
increased marketing costs for HeartScan,  a wholly-owned  subsidiary of Imatron.
General and administrative expenses increased 6% in 1995 as compared to 1994.

The  increase  in other  income  in 1995 is a result of the  elimination  of the
$4,000,000  term loan with  Siemens in exchange for the transfer of five Imatron
EBT  patents  and  the  cancellation  of  Siemens'   existing  minimum  purchase
obligations under the previous distribution agreement.

Interest  expense  decreased  44%  as  compared  to  1994  primarily  due to the
elimination of the $4,000,000 term loan with Siemens.

                         Report of Independent Auditors


Board of Directors and Shareholders
Imatron Inc.

We have audited the accompanying  consolidated balance sheets of Imatron Inc. as
of  December  31,  1996 and 1995,  and the related  consolidated  statements  of
operations,  shareholders' equity, and cash flows for each of the three years in
the period  ended  December  31, 1996.  Our audits also  included the  financial
statement  schedule  listed  in the  index  at Item 14 (a).  These  consolidated
financial  statements  and  schedule  are the  responsibility  of the  Company's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements and 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 consolidated financial position of Imatron
Inc.  at  December  31,  1996 and  1995,  and the  consolidated  results  of its
operations  and its cash flows for each of the three  years in the period  ended
December 31, 1996, in conformity with generally accepted accounting  principles.
Also, in our opinion, the related financial statement schedule,  when considered
in relation to the basic financial statements taken as a whole,  presents fairly
in all material respects the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                December 31, 1996

Note 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF COMPANY

Imatron   Inc.,  a  New  Jersey   corporation   incorporated   in  1983,   is  a
technology-based  company  principally  engaged in the  business  of  designing,
manufacturing, and marketing a high performance computed tomography scanner. The
scanner  is used in large and  mid-sized  hospitals  and free  standing  imaging
clinics.  The Company provides  service,  parts and maintenance to hospitals and
clinics that operate its scanners.  In addition,  the Company operates  coronary
artery scanning test facilities  through its  consolidated  subsidary  HeartScan
Imaging, Inc. ("HeartScan"),in the United States.

The consolidated  financial  statements include the accounts of Imatron Inc. and
its  subsidiary  HeartScan  Imaging,  Inc.  (collectively  the  "Company").  All
intercompany accounts and transactions have been eliminated in consolidation.


HeartScan  was  incorporated  in  Delaware  in 1994.  As of  December  31,  1996
Imatron's  interest in HeartScan is 49.5% (see Note 7). On June 28, 1996 Imatron
sold 100,000 shares of HeartScan Series A preferred stock to unaffiliated  third
parties.  The sale  reduced the  Company's  ownership  interest in  HeartScan to
48.3%.  Imatron originally  reported $554,000 (48.3%) of HeartScan losses in its
third  quarter  of fiscal  1996  using the  equity  method  of  accounting.  The
remaining  losses of $594,000 were  attributed to the preferred  stock ownership
interest of HeartScan in the third quarter of fiscal 1996. Due to certain equity
exchange provisions provided to these HeartScan preferred shareholders (see note
7),  HeartScan's 1996 results of operations have been fully consolidated for the
year  ended  December  31,  1996  in  the  accompanying  consolidated  financial
statements.  The result of the  consolidation  of HeartScan  was to increase the
Company's net loss by $4,573,000  for the year ended  December 31, 1996. Of this
amount,  $594,000 of losses that were  originally  attributed  to the  preferred
shareholders'  ownership  interest  in the third  quarter  of 1996 have now been
consolidated  with the  Company's  1996 losses.  No future  HeartScan  operating
losses will be  attributed  to the  preferred  shareholders  until the preferred
stock  exchange  provisions  are  extinguished.  Additionally,  the net proceeds
realized from the  Heartscan  preferred  stock  offering will be classified as a
minority interest in the Company's  balance sheet until the exchange  provisions
are extinguished.

The  Company's  results  of  operations  in fiscal  1996  includes  revenues  of
$1,293,000 attributed to HeartScan's operations.



USE OF ESTIMATES

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.


<PAGE>


CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

Cash equivalents consist of liquid instruments purchased with a maturity date of
three months or less and money market  funds.  In accordance  with  Statement of
Financial  Accounting  Standards No. 115, "Accounting for Certain Investments in
Debt and Equity  Securities,"  the Company has  classified all 1996 purchases of
investments as available-for-sale.  Available-for-sale securities are carried at
amounts which  approximate fair value, with unrealized gains and losses reported
in a separate  component of shareholders'  equity,  if material.  Fair values of
investments  are  based on  quoted  market  prices.  Short-term  investments  at
December 31, 1996 consist of A1, P1 commercial papers and government securities.

As  of  December  31,  1995,  the  company  classified  certain  investments  as
held-for-maturity.   All  held-to-maturity   investments  matured  during  1996.
Management determines the appropriate classification of marketable securities at
the time of purchase and reevaluates  such  designation as of each balance sheet
date.

Realized   gains   and   losses,   and   declines   in   value   judged   to  be
other-than-temporary  are included in other income.  The cost of securities sold
is based on the specific identification method.

CONCENTRATIONS OF RISK

The  Company's  primary  customers  operate  in  the  healthcare  industry.  The
healthcare  industry is highly regulated.  Both existing and future governmental
regulations  could  adversely  impact the market for the Company's  Ultrafast CT
scanner and the Company's business. The Company's operations are also subject to
regulation by other federal,  state and local governmental entities empowered to
enforce  pertinent  statutes  and  regulations,  such as those  enforced  by the
Occupational Safety and Health Agency and the Environmental Protection Agency.

The Company sells its products  primarily through exclusive  distributors in the
United States,  Europe,  Canada, India, Imatron Japan, Inc. in Japan, as well as
other  distributors  in the Pacific  rim.  The  Company  usually  requires  cash
deposits  based on a percentage of the sales price and maintains  allowances for
potential credit losses. Such losses have been within management's expectations.

The Company invests its excess cash in short-term  instruments  with at least an
A1/P1 credit  rating.  These funds have  virtually no principal  risk and have a
variable  interest rate. The Company has not experienced any principal losses on
its investments.

The Company revenues are principally derived from the Ultrafast CT scanner. Many
of the components and sub-assemblies used in the scanner have been developed and
designed by Imatron to its custom specifications and are obtainable from limited
or single sources of supply.  In view of the customized  nature of many of these
components and sub-assemblies,  there may be extended delays between their order
and delivery.  Delays in such delivery could adversely affect Imatron's  present
and future  production  schedules.  The Company has made and  continues  to make
inventory investments to acquire long lead time components and sub-assemblies to
minimize the impact of such delays.  In recent years,  the Company has developed
alternative  sources for many of its scanner  subcomponents  and  continues  its
programs to qualify vendors for the remaining critical parts.

INVENTORIES

Inventories are stated at the lower of standard cost (which approximates cost on
a first-in,  first-out basis) or market.  Provisions are made in each period for
<PAGE>

the  estimated  effects of excess and obsolete  inventories.  Actual  excess and
obsolete   inventories  may  differ  from  the  Company's   estimates  and  such
differences could be material to the consolidated financial statements.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost and are depreciated on a straight-line
method over their  estimated  useful lives (3-5 years).  Equipment under capital
leases, except for scanner equipment,  and leasehold  improvements are amortized
on a straight-line method over the lesser of their estimated useful lives or the
remaining term of the related leases.

Scanner  equipment  under  capital  lease is  amortized  over a period using the
units-of-production  method based on the estimated usage of the equipment. It is
reasonably  possible  that the  estimates of  anticipated  scans,  the remaining
useful  lives,  or both will be reduced  significantly  in the near  term.  As a
result, the carrying amount of the scanner equipment could be reduced materially
in future periods.

RESTRICTED CASH

In connection  with a sales agreement in 1994, the Company has issued letters of
credits to a purchasor related to performance bond requirements.  The letters of
credit are  collaterized  by  certificates  of deposit  totalling  approximately
$160,000  and  $155,000 at December  31,1996 and 1995  respectively.  These this
restricted cash amounts have been classified as non-current  assets (included in
other assets).

JOINT VENTURE COMPANY

In 1994,  the  Company  formed a joint  venture,  Imatron  Japan,  Inc.  ("Joint
Venture") with two unrelated parties.  Imatron holds a 24% interest in the Joint
Venture,  which is carried at no value in the accompanying  consolidated balance
sheets.  Imatron has no  financial  commitments,  and is prepared to abandon its
interest in the Joint Venture,  which is being funded by the other joint venture
partners.

The Company  recognized  revenues of $8,726,000 and $9,213,000 in 1996 and 1995,
respectively,  from sales to the Joint Venture and has $2,660,000 and $2,957,000
in accounts  receivable  from the Joint  Venture at December  31, 1996 and 1995,
respectively.

REVENUE RECOGNITION

Revenues  related to product sales are recognized  upon shipment to the customer
or to a customer designated location,  at which time title and risk of ownership
passes. The Company accrues for estimated installation and warranty costs at the
time of sale.  Revenues  related  to service  are  recognized  ratably  over the
relevant  contractual  period or as the service is  performed.  Service  revenue
billed but  unearned  is included on the  consolidated  balance  sheets as other

<PAGE>

accrued  liabilities.  Revenues related to development  contracts are recognized
ratably over the contract.  Revenues from clinics are  recognized  when services
are performed for the clinic customer.

RESEARCH AND DEVELOPMENT

Research and development expenditures are charged to operations as incurred.

NET INCOME / (LOSS) PER SHARE

Net loss per common share in 1996 and 1995 has been computed  using the weighted
average number of common shares outstanding. Net income per common share in 1994
has been computed using the weighted average number of common shares outstanding
after considering the dilutive effect of convertible preferred shares (using the
"as if"  converted  method) and common  stock  options and  warrants  (using the
"treasury stock" method).

losses in any category of investment in 1996 or 1995.

Note 3  -  TRANSACTIONS WITH SIEMENS CORPORATION


In March 1995, the Company and Siemens  Corporation  ("Siemens")  entered into a
Memorandum of Understanding.  Under the terms of the Memorandum,  Siemens agreed
to provide a maximum $15 million to the Company's C-150  Evolution  Ultrafast CT
scanner  research and development  program over the next three years in order to
improve and  enhance the  scanner.  Imatron  funds a portion  equal to a minimum
fifty percent of Siemens'  contribution  for the sole purpose of conducting  the
collaborative  agreement.  In connection  with this  agreement,  Siemens retains
exclusive  distribution rights,  through March 31, 1998, in certain geographical
regions for sales of the  C-150/Evolution  scanner.  The Company has  recognized
$5,000,000  and  $3,884,000  of  revenue  under  the  collaborative  development
agreement  in  1996  and  1995,  respectively.  Under  the now  expired  product
development agreement with
<PAGE>

Siemens,  the Company  recognized  $0,  $1,753,000  and $5,013,000 in revenue in
1996, 1995 and 1994, respectively.

In conjunction with this Memorandum of  Understanding,  Imatron  transferred the
ownership  of five  Imatron  EBT patents to Siemens  and  cancelled  the minimum
purchase  provision of the previous  distribution  agreement in  satisfaction of
Imatron's $4 million note payable to Siemens.  Imatron has classified the entire
$4 million as other income in 1995.

In September 1995,  Siemens  asserted a claim against the Company  regarding the
lapse of certain foreign registrations of one of the patents assigned to Siemens
by the  Company in  connection  with the March 31,  1995  agreement  between the
companies. The technology involved in the patent is not used presently in any of
the Company's products.  The Company  substituted a patent,  subject to existing
license-back,  currently used in its technology,  for the previously transferred
patent. Representatives of Siemens have agreed with the Company to these terms.

The Company sold two scanners to leasing finance institutions during fiscal 1996
and 1995,  which  were  immediately  leased  back to  HeartScan.  The sales were
accounted for as  sales-leaseback  transactions.  Remaining  deferred  income on
sale-leaseback  transactions  amounted to $1,419,000  and $1,267,000 at December
31, 1996 and 1995, respectively.

LICENSE AGREEMENTS

In February  1981,  the Company was granted the exclusive use for five years and
nonexclusive use thereafter of certain  technology and a patent pending owned by
the  University of California  ("UC") under the terms of license and  sublicense
agreements  between UC and  Emersub  Incorporated  ("Emersub"),  a wholly  owned
subsidiary  of Emerson  Radio Corp.,  and Emersub and Imatron  Associates,  (the
predecessor  to the  Company),  respectively.  In June  1986,  the  license  and
sublicense  agreements were amended to extend the Company's exclusive use of the
technology  through the  remaining  life of the patent in exchange  for modified
annual royalty  payments.  The sublicense  agreement,  as amended,  requires the
Company to pay annual  royalties to Emersub  equal to 2.125% of the net sales of
products utilizing the licensed technology. Charges to operations for 1996, 1995
and 1994 were $91,470, $91,470 and $151,980, respectively.

Note 7  -  CAPITAL STOCK

COMMON STOCK

In 1995, the Company closed a private placement of its common stock.
The private  placement  realized  proceeds of $9,882,000 (net of offering costs)
through the sale of 1,200,000  units.  A unit consists of five shares of Imatron
Inc. Common Stock and one five-year  Imatron Inc. Common Stock purchase warrant.
In  connection  with the private  placements,  the Company  issued an additional
91,819  units as a result  of the  adjustment  on the stock  price  based on the
60-day  average  price as stated in the Common  Stock  purchase  agreement.  The
adjusted price per unit was $8.25 or $1.65 per share of Common Stock.

In 1996,  Imatron sold 4,500,000  shares of common stock and issued  warrants to
purchase common shares in two private placement  offerings,  netting proceeds of
$11,348,000.  In addition,  in 1996, the company issued additional 59,093 shares
of common  stock as a result of the  adjustment  on the stock price based on the
60-day average price  pertaining to the previous 1995 private  placement.  As of
December  31,  1996,  no further  rights for  adjustments  remain for the common
stock.

HEARTSCAN EQUITY TRANSACTIONS

In June 1996,  Imatron  completed a private  placement  offering whereby 100,000
shares of  HeartScan  Series A  Preferred  Stock were sold at $160 per share and
realized net proceeds of  $14,798,000.  The preferred  stock is convertible on a
ten-to-one basis into HeartScan common shares at any time.  Mandatory conversion
of the  preferred  stock  into  common  stock  will  occur  upon the  successful
completion  of a HeartScan  initial  public  offering.  The  HeartScan  Series A
Preferred  Stock may be  exchanged at the sole option of the holder into Imatron
common stock at an exchange price of $5.00 per share until the earlier of a) two
year period following closing of the Preferred Stock offering; or b) a HeartScan
initial public offering. If there is no initial public offering within 24 months
of the  Preferred  Stock  closing,  holders may convert the  HeartScan  Series A
Preferred  Stock into Imatron  common  stock at a conversion  price equal to the
greater of $1.50 per share or a 27% discount from the weighted  average  closing
price of Imatron  common  stock for the 90 day period  immediately  preceding 24
months of the Preferred Stock closing and each date that is 3 months  thereafter
to and including the 48th month of the Preferred Stock closing.

<PAGE>

Due to the exchange  provision  built into the private  offering as discussed in
the preceding paragraph,  Imatron will include HeartScan's results of operations
in its consolidated financial statements until either the conclusion of the four
year exchange period or a HeartScan initial public offering.

The HeartScan Series A Preferred Stock is held entirely by an unaffiliated third
parties and is  classified  in the  accompanying  consolidated  balance sheet at
December 31, 1996 as a minority interest.

The  terms of the  preferred  stock  provide  certain  additional  rights to the
holders  including  participation  and approval of any future  HeartScan  equity
financing and approval of transactions with affiliates.

The terms of the Series A Preferred Shares include  1,000,000  authorized shares
and 100,000 issued and outstanding shares at December 31, 1996.

As of December 31, 1996, 30,002 warrants to purchase one share each of HeartScan
Common  Stock  were  issued  in  connection  with  the  above-mentioned  private
placement. These warrants are exercisable at $16.00 per share and expire in June
2001.

Note 8 -  STOCK BONUS PLAN AND STOCK OPTION PLANS

STOCK BONUS PLAN

In  February  1987,  the  Company  adopted  the 1987 Stock  Bonus Plan which was
approved by the shareholders.  The stock bonus plan was adopted to reward and to
provide  incentive  to  participants  for  services.  The total number of common
shares that may be granted is 1,200,000 with no more than 400,000 shares
<PAGE>

awarded in any fiscal year. In 1996, the Company granted 19,409 shares under the
plan.  There  were no shares  granted  under  the plan in 1995 and  1994.  As of
December 31, 1996, 770,910 common shares are reserved for future grants.

DIRECTOR STOCK OPTION PLAN

In June 1991, the Company  adopted a non-employee  Directors'  Stock Option Plan
for the  directors of Imatron.  The  Directors  Plan  provides for the automatic
grant of  non-statutory  options to non-employee  directors.  The Directors Plan
covers 250,000 shares of the Company's  common stock.  In June 1993 an amendment
to the non-employee  Directors Plan was approved increasing the number of shares
to 550,000.  Under the plan,  options for  425,000  shares have been  granted to
non-employee Directors.

EMPLOYEE STOCK OPTION PLAN

In March 1983,  the Company  adopted a stock option plan which  provides for the
granting of incentive stock options to employees and nonstatutory  stock options
to nonemployee directors, and certain consultants. The shareholders approved the
plan,  as  amended,  in March 1984.  In 1993 the  original  plan  ("1983  Plan")
terminated and a new plan ("1993 Plan") was approved. The terms of the 1993 Plan
are consistent  with the terms of the 1983 Plan.  During 1995, the  shareholders
approved  an increase  in the number of shares  reserved  for the 1993 Plan from
3,000,000 to 5,500,000.

All incentive  stock options are granted at the common stock's fair market value
at the grant date and  nonstatutory  stock  options are granted at not less than
85% of the common stock's fair market value at the grant date.  Options  granted
under the plan  generally  vest evenly over four years  following the grant date
and expire five years from the grant date.

STOCK BASED COMPENSATION

The Company has elected to follow Accounting  Principles Board Opinion No. 25, "
Accounting for Stock Issued to Employees ("APB 25") and related  Interpretations
in accounting for its employee stock options  because,  as discussed  below, the
alternative  fair value  accounting  provided for under FASB  Statement No. 123,
"Accounting for Stock-Based  Compensation" ("SFAS 123"),  requires use of option
valuation models that were not developed for use in valuing stock options. Under
APB 25,  compensation  expense is measured as the excess of the market  price of
the underlying stock over the exercise price on the date of the grant, if any.

Pro forma information  regarding net loss and loss per share is required by SFAS
123, and has been  determined  as if the Company has  accounted for its employee
stock options under the fair value method of that  Statement.  The fair value of
these  options was estimated at the date of grant using a  Black-Scholes  option
pricing model with the following weighted-average assumptions:

                                             1996                      1995
                                             ----                      ----

  Expected stock price volatility           80.2%                     80.2%
  Risk-free interest rate                    6.25%                     6.37%
  Expected life - Years                      3.64                      3.55
  Expected dividend yield                    0.00%                     0.00%

The Black-  Scholes option  valuation  model was developed for use in estimating
the fair value of traded  options  which have no  vesting  restrictions  and are
fully  transferable.  In addition,  option valuation models require the input of
<PAGE>

highly  subjective  assumptions  including the expected stock price  volatility.
Because the Company's employee stock options have characteristics  significantly
different from those of traded  options,  and because  changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion,  the  existing  models do not  necessarily  provide a  reliable  single
measure of the fair value of its employee stock options.

For purposes of pro forma  disclosures,  the estimated fair value of the options
is  amortized  to expense  over the  options'  vesting  period.  Had the Company
elected to recognize compensation expense based on the fair value of the options
granted at grant dates as  prescribed  by SFAS 123,  net loss and loss per share
would have been increased to the pro forma amounts  indicated in the table below
(in thousands):

                                                1996                1995
                                             ----------          ----------
 Net loss - as reported                       ($10,465)           ($2,449)
               Net loss - pro forma           ($10,884)           ($2,620)
               Loss per share - as reported     ($0.14)            ($0.04)
               Loss per share - pro forma       ($0.15)            ($0.05)

The weighted  average  fair value of options  granted in 1996 and 1995 was $2.63
and $1.24 per share,  respectively.  The weighted average remaining  contractual
life of all options at December 31, 1996 is 3.64 years.

The pro forma effect on net loss for 1996 is not representative of the pro forma
effect on net income in future years because it does not take into consideration
pro  forma  compensation  expense  related  to  grants  prior to  1995,  and the
compensation  expense  that will be  recognized  in future  years as the  graded
vesting periods become exercisable.

Note 9  -  STOCK PURCHASE PLAN AND RETIREMENT SAVINGS PLAN

EMPLOYEE STOCK PURCHASE PLAN

In March 1994, the Company adopted an employee stock purchase plan covering most
employees.  Under  the  plan,  employees  may  contribute  up to  10%  of  their
compensation to purchase  shares of the Company's  common stock at the lesser of
85% of the  stock's  fair  market  value at the  offering  period or end of each
three-month  interim offering period. The maximum number of shares offered under
the Plan is 1,800,000  shares of common  stock.  At December  31, 1996,  727,095
shares were reserved and available for future  issuance  under the plan. A total
of 228,222, 334,975 and 503,243 shares were issued at an average price of $1.44,
$0.75 and $0.75 per share in 1996, 1995 and 1994, respectively.

RETIREMENT SAVINGS PLAN

In 1987,  the  Company  established  a  qualified  retirement  plan,  under  the
provisions of section  401(K) of the Internal  Revenue  Code, in which  eligible
employees may participate.  Substantially all participants in this plan are able
to defer  compensation  up to the  annual  maximum  amount  allowable  under the
Internal  Revenue Service  regulations.  The Plan was amended in 1994 to provide
for   employer   contributions   equal  to  50%  of  every  dollar  of  employee
contribution,  with a maximum of 6% of employee wages.  The Company  contributed
approximately   $212,000,   $169,000  and  $76,000  in  1996,   1995  and  1994,
respectively.

Due to the issuance of preferred stock which occurred June 28, 1996, utilization
of the net operating loss and tax credit  carryforwards  for the Company and its
subsidiary, HeartScan, will be subjected to separate return limitations.

At  December  31,  1996 the Company has net  operating  loss  carryforwards  for
federal  and  state  income  tax  purposes  of  approximately   $61,200,000  and
$10,600,000 respectively. Additionally, the Company has research and development
and alternative  minimum tax credit  carryforwards of approximately  $842,000 at
December 31, 1996. The net operating loss and the research and  development  tax
credit carryforwards expire in various years from 1998 through 2011.
