Item 1.  DESCRIPTION OF BUSINESS

GENERAL

     Positron Corporation (the "Company") was incorporated in the State of Texas
on December 20, 1983, and commenced commercial operations in 1986. The Company
designs, manufactures, markets and services, advanced medical imaging devices
utilizing positron emission tomography ("PET") technology under the tradename
POSICAM(TM) systems. Unlike other currently available imaging technologies, PET
technology permits the measurement of the biological processes of organs and
tissues as well as producing anatomical and structural images. POSICAM(TM)
systems, which incorporate patented and proprietary technology, enable
physicians to diagnose and treat patients in the areas of cardiology, neurology
and oncology. The United States Food and Drug Administration approved the
initial POSICAM(TM) system for marketing in 1985, and as of December 31, 1996,
the Company has sold twenty (20) POSICAM(TM) systems, of which fifteen (15) are
in leading medical facilities in the United States, two (2) are installed in
international medical institutions and three (3) are no longer operational. The
Company presently markets its POSICAM(TM) systems at list prices ranging from
approximately $1.0 million to $1.8 million depending upon the configuration and
equipment options of the particular system.

     The following table provides summary information regarding the Company's
installed base of POSICAM(TM) systems, which were operational as of December 31,
1996:

     PET technology is an advanced imaging technique which permits the
measurement of the biological processes of organs and tissues as well as
producing anatomical and structural images.  Other advanced imaging techniques,
such 

                                       2

as magnetic resonance imaging ("MRI") and computerized axial tomography
("CAT") scans, produce anatomical and structural images, but do not image or
measure biological processes.  The ability to measure biological abnormalities
in tissues and organs allows physicians to detect disease at an early stage and
provides physicians with information, which would otherwise be unavailable, to
diagnose and manage the treatment of disease.  The Company believes that PET
technology can lower the total cost of managing certain diseases by providing a
means for early diagnosis and reduction of expensive invasive or unnecessary 
procedures, such as angiograms or biopsies which in addition to being costly 
and painful, may not be necessary or appropriate.

     Commercial utilization of PET technology commenced in the mid-1980s and the
Company is one of three commercial manufacturers of PET imaging systems in the
United States.  Although the other two major manufacturers are substantially
larger, the Company believes that its POSICAM(TM) systems have proprietary
operational and performance characteristics which give it certain performance
advantages over other commercially available PET systems.  Such performance
advantages include the POSICAM(TM) systems' high count-rate sensitivity which
results in faster imaging, an enhanced ability to use certain types of
radiopharmaceuticals which minimize patient exposure to radiation and its
ability to minimize false positive and false negative diagnoses of disease.  The
industry in which the Company is engaged is, however, subject to rapid and
significant technological change.  There can be no assurance that the
POSICAM(TM) systems can be upgraded to meet future innovations in the PET
industry or that new technologies will not emerge, or existing technologies will
not be improved, which would render the Company's products obsolete or non-
competitive.  See "Item 1. Description of Business--Risks Associated with
Business Activities--Substantial Comptetition and Effects of Technological
Change."  Based on industry information, the Company estimates that 67 PET
systems are currently commercially installed in the United States.  Of the PET
systems currently operational in the United States, 15 systems were sold by the
Company.  The Company believes that the other two major manufacturers of
commercial PET systems have together 37 currently operational PET systems.

     The Company's primary focus to date has been on the clinical cardiology
market, where its POSICAM(TM) systems have been used to assess diseases, such as
the effect of arterial blockages and heart damage due to heart attacks.  In 1994
and 1995 the Company made technological advances which allowed it to market its
products to the neurological and oncological markets.  Neurological applications
of POSICAM(TM) systems include diagnoses of certain brain disorders, such as
epileptic seizures, dementia, stroke, Alzheimer's disease, Pick's disease and
Parkinson's disease.  In oncology, POSICAM(TM) systems are used in the diagnosis
and evaluation of tumors of the bone and various organs and tissues such as the
brain, liver, colon and breast.

     The Company has expanded its marketing efforts to include Europe, as well
as certain Asian and Middle Eastern markets.  The Company currently has a
distribution agreement with Elscint, Ltd. ("Elscint") for the distribution of
its products in Europe, Asia and the Middle East.  Elscint is an Israel-based,
international medical diagnostic equipment manufacturer, and one of the leading
distributors of nuclear medicine products.

     Additionally, in January 1997, the Company entered into a sales and
marketing agreement with Beijing Aerospace Chang Feng Medical ("Chang Feng") to
sell the Company's products in the Peoples Republic of China ("PRC").  The
initial term of the agreement is for twelve (12) months.  Thereafter, the
agreement is renewable at the mutual agreement of the parties.  Chang Feng is
Beijing, PRC based and is the largest supplier of CT and MRI imaging technology
in the PRC and is a joint venture partner with General Electric Company for the
manufacture and distribution of CT and MRI products.

MEDICAL IMAGING INDUSTRY OVERVIEW

     Diagnostic imaging allows a physician to assess disease, trauma or
dysfunction without the necessity of surgery.  The diagnostic imaging industry
includes ultrasound, X-ray, MRI, CAT scans, and nuclear medicine (which includes
PET technology and single-photon emission computed tomography ("SPECT")).  MRI
technology uses powerful magnetic fields to provide anatomical and structural
images of the brain, the spine and other soft tissues, as well as determining
the location and size of tumors.  CAT scans use X-ray beams to obtain anatomical
and structural images of bones and organs.  Nuclear medicine focuses on
providing information about the function and biological processes of organs and
tissues through the use of radiopharmaceuticals.

                                       3

     The first prototype PET scanner was developed in the mid 1970s and the
first commercial PET scanner was constructed in 1978.   In addition to the
estimated 67 PET systems currently operational in the United States, an
additional  88 PET systems are in commercial use outside of the United States.

PET TECHNOLOGY

     The PET imaging process begins with the injection of a radiopharmaceutical
(a drug containing a radioactive agent) by a trained medical person into a
patient's bloodstream.  The injected radiopharmaceutical undergoes a process of
radioactive decay, whereby positrons (positively charged electrons) are
converted into light energy, or photons.  These photons are detected by the
POSICAM(TM) systems.  The source of the photons is determined and is
reconstructed into a color image of the scanned organ utilizing proprietary
computer software.  Since the concentration of the radiopharmaceutical is
determined by certain functional processes in the organ, such as blood flow,
metabolism or other biochemical processes, the brightness or color at each point
in the PET image directly maps the vitality of the respective function at that
point within the organ.

     The Company believes market timing for PET is substantially strengthened as
the nation's healthcare system evolves toward a concept of improved patient
outcome and appropriateness of treatment at reduced costs.  Healthcare
consolidation is occurring at a rapid pace in anticipation of becoming more
competitive and able to attract payor contracts.  Third party payors are
beginning to monitor provider outcomes.  Those providers who do not perform
within norms will lose patients as third party payors shift to others who
conform with standardized treatments with expected results.  The Company
believes the accuracy of PET will enable clinicians to achieve improved outcome.
See, however, "Item 1. Description of Business--Risks Associated with Business
Activities."

     PET imaging is an accurate non-invasive method of diagnosing or assessing
the severity of coronary artery disease.  Unlike other imaging technologies, PET
technology allows a physician to determine whether blood flow to the heart
muscle is normal, thereby identifying narrowed coronary arteries, and whether
damaged heart muscle is viable and may benefit from treatments such as bypass
surgery or angioplasty.

     In neurology, PET imaging is now being used as a surgical planning tool to
locate the source of epileptic disturbances in patients with uncontrollable
seizures.  A 1994 study has shown that a PET examination may offer an effective
alternative to the traditional method of diagnosis, which involves a surgical
procedure in which the surface of the brain is exposed and electrodes are
applied for a period of up to one week to map electrical activity.  In other
neurological applications, PET is used in the diagnosis of dementia, Alzheimer's
disease, Pick's disease and Parkinson's disease and in the evaluation of stroke
severity.

     In oncology, PET imaging is currently used to measure the metabolism of
tumor masses after surgery or chemotherapy.  Clinical experience has shown that
PET is more accurate than CAT scans or MRI in determining the effectiveness of
chemotherapy and radiotherapy in the treatment of cancer.  Scans used to assess
suspected breast cancer are still in the experimental stage.  Whole body scans,
however, are now routinely performed with PET to survey the body for cancer.

     The Company believes that PET imaging can lower the total cost of managing
certain diseases by providing a means for early diagnosis and reduction of
unnecessary follow-up invasive procedures which can be costly and painful.  The
Company estimates that the cost to the patient for PET procedures ranges between
$1,500 and $2,200 for cardiac applications and between $1,800 and $3,000 for
neurology and oncology applications.  In contrast, the traditional technique for
diagnosing coronary artery disease is an angiogram, an invasive procedure in
which a catheter is inserted into the vessels of a patient's heart to assess the
degree of coronary artery blockage, and generally costs between $5,000 and
$7,500.  In cases where a PET scan indicates the need for surgery, it is
anticipated that a follow-up angiogram would be performed for cardiac surgical
planning.  The traditional alternative to PET scans in neurology and oncology
applications is a biopsy or other invasive surgical procedure, which would
typically be more costly and painful than a PET scan.

     The radiopharmaceuticals (together with the radioactive substances
contained therein) employed in PET scanning are used by the organ in its natural
processes (such as blood flow and metabolism) without affecting its normal

                                       4

function, and quickly dissipate from the body.  Radiopharmaceuticals used in PET
procedures expose patients to a certain amount of radiation, which exposure is
measured in units of rads.  Exposure to radiation can cause damage to living
tissue, and the greater the radiation exposure the greater the potential for
damage.  Certain PET procedures expose a patient to less radiation than would be
associated with other imaging technologies.  A PET cardiac scan, using the
radiopharmaceutical Rubidium-82 results in exposure of approximately 0.096 rad,
while a neurology PET scan results in exposure of approximately 0.39 rad.  In
contrast, a typical chest X-ray results in exposure of approximately 0.15 rad
and a CAT scan results in exposure to between approximately 0.5 rad and 4.0 rad,
depending on the procedure.

     Radiopharmaceuticals used in PET technology can be created from many
natural substances including carbon, oxygen, nitrogen and fluorine.  The PET
procedure to be performed determines the type of radiopharmaceutical.
Radiopharmaceuticals are made ready for use at a clinic or hospital by either a
cyclotron or a generator.  Cyclotrons require an initial capital investment of
approximately $2 million, additional capital investment for site preparation,
and significant annual operating expenses.  A generator requires an initial
capital investment of approximately $50,000, no additional capital investment
for site preparation, and monthly operating expenses of approximately $25,000.
While POSICAM(TM) systems have been designed to be used with both cyclotron and
generator processed radiopharmaceuticals, they have proprietary design features
which enhance their ability to use generator processed radiopharmaceuticals,
thereby allowing a clinic or hospital which intends to focus on certain cardiac
PET applications to avoid the significant capital and operating expenses
associated with a cyclotron.

MARKETING STRATEGY

     The Company initially targeted clinical cardiology as its marketing
strategy based on research conducted at the University of Texas Health Science
Center in Houston, Texas, which showed the commercial potential of clinical
cardiology applications of PET imaging.

     The Company estimates that there are approximately 2,100 potential sites in
the United States for cardiac PET systems alone.  This estimate is based on a
potential user base of approximately 900 hospitals with over 350 beds each,
approximately 50 cardiology groups with 15 or more doctors each, and 1,200 free-
standing diagnostic imaging centers and mobile facilities.

     The Company believes that it has a competitive advantage in the cardiac PET
market.  POSICAM(TM) systems have the ability to produce accurate images by
using generator produced radiopharmaceuticals which can be obtained without the
significant initial capital investment associated with cyclotron produced
radiopharmaceuticals.  The Company also believes that the high count-rate
sensitivity of the POSICAM(TM) systems, which results in faster imaging, the
ability of the POSICAM(TM) systems to use generator produced
radiopharmaceuticals which minimize patient exposure to radiation and certain
proprietary design features of the POSICAM(TM) systems which minimize false
positive and false negative diagnoses of disease give the Company additional
competitive advantages.  See "Item 1. Description of Business--Risks Associated
with Business Activities."

     Historically, the PET neurology market has been primarily research-
oriented, but recent developments have expanded the use to clinical
applications, including the identification of the source of uncontrollable
epileptic seizures, the diagnosis of such neurological disorders as dementia,
Alzheimer's disease, and the determination of stroke severity.  Six POSICAM(TM)
system sites that initially utilized PET in cardiology are now expanding their
use to neurological applications.  In oncology, work is being conducted at major
cancer and other medical centers, utilizing POSICAM(TM) imaging to determine
tumor size, monitor tumor therapy, and evaluate the effectiveness of
radiotherapy and chemotherapy.

     The Company utilizes a direct sales force of three account executives to
market its products in the United States, and has entered into  third party
distribution arrangements in order to penetrate foreign markets. Additionally,
the Company has relied on referrals from users of the Company's existing base of
installed scanners, clinical presentations at professional conferences by
customers of the Company, and published articles in trade journals to market its
systems.

                                       5
<PAGE>
 
     In July 1993, the Company entered into an equipment distribution agreement
with Elscint in an effort to increase the market presence and sales of its
POSICAM(TM) systems in Europe, Asia and certain areas of the Middle East.
Elscint is an international medical diagnostic equipment manufacturer with
distribution subsidiaries located in the world's major markets.  The equipment
distribution agreement was for an initial term of two years and continues
thereafter on a year-to-year basis.  The Company may terminate the distribution
agreement at any time, since at the end of the initial two year term, Elscint
had not placed orders for at least three (3) POSICAM(TM) systems.  The
distribution agreement contains no minimum purchase requirements by Elscint.  To
date, one purchase order for a POSICAM(TM) HZL system has been received under
the Elscint agreement.

     Additionally, in January 1997, the Company entered into a sales and
marketing agreement with Beijing Aerospace Chang Feng Medical ("Chang Feng") to
sell the Company's products in the Peoples Republic of China ("PRC").  The
initial term of the agreement is for twelve (12) months.  Upon expiration of the
initial term, the agreement is renewable upon the mutual consent of the parties.
Pursuant to the agreement Chang Feng is required to use its "best commercial
efforts" to sell a minimum of two POSICAM(TM) systems during the initial term of
the agreement.


THE POSICAM(TM) SYSTEM

     At the heart of the POSICAM(TM) system is its detector assembly which
detects positron emissions and electronic circuits which pinpoint the location
of those positron emissions.  POSICAM(TM) systems are easy to use and are not
physically confining thereby not intimidating to patients.   POSICAM(TM) scans
are commonly performed on an outpatient basis.

     The Company's systems currently have the highest count rate sensitivity in
the PET industry.  Count rate sensitivity of an imaging system is its ability to
detect, register and assimilate the greatest number of meaningful positron
emission events in the shortest period of time.  The higher count rate
sensitivity of the POSICAM(TM) systems results in superior diagnostic accuracy
as measured by fewer false positives and false negatives.  Further benefits of
high count rate sensitivity include faster imaging and the ability to use short
half-life radiopharmaceuticals, which reduces patient exposure to radiation and
may reduce the capital cost to some purchasers by eliminating the need for a
cyclotron for certain cardiac applications.

     The detector assembly consists of crystals, which scintillate (give off
light) when exposed to positron emissions, and photomultiplier tubes which are
coupled to the crystals and convert the scintillations into electrical impulses.
The Company employs its own patented staggered crystal array design for the
POSICAM(TM) detectors which, unlike competing PET systems, permits the
configuration of the detector crystals into overlapping series to create a
higher quality image by eliminating image sampling gaps.  This feature is
important since undersampling or gaps in sampling can contribute to an
inaccurate diagnosis.  The crystal array design also reduces "dead time" (the
time interval following the detection and registering of a positron emission
during which a subsequent event cannot be detected).

     The POSICAM(TM) system currently creates the most and, the most finely
spaced, image slices in the PET industry.  An image slice is a cross-sectional
view that is taken at an arbitrary angle to the angle of the organ being scanned
and is not necessarily the angle which a physician wishes to view.  The
POSICAM(TM) computer can then adjust the cross-sectional view to create an image
from any desired angle.  The high number of finely spaced image slices created
by the POSICAM(TM) system enhances the accuracy of the created image.

     An integral part of a POSICAM(TM) system is its proprietary data
acquisition micro-processor and its application system software.  The Company's
software can reconstruct an image in five seconds or less.  The Company has
expended substantial effort and resources to develop the computer software to
insure that it is user-friendly and clinically oriented.  The only personnel
needed to perform clinical studies with the POSICAM(TM) systems are a trained
nurse, a trained technician and an overseeing physician for patient management
and safety.

     POSICAM(TM) HZ AND HZL.   In addition to the basic POSICAM(TM) system, the
Company offers two advanced versions of its basic system which are known as the
POSICAM(TM) HZ and the POSICAM(TM) HZL.  Oncologists and 

                                       6
<PAGE>
 
neurologists require enhanced resolution and a large field of view to detect 
small tumors and otherwise scan large organs, such as the liver.  The 
POSICAM(TM) HZ and HZL employ  new detector concepts to satisfy these needs 
while maintaining the high count rate sensitivity of the basic POSICAM.(TM)  
In May 1991, the Company received approval from the FDA to market the 
POSICAM(TM) HZ and in May 1993, the Company received a patent for the 
innovative light guide and detector staggering concepts used in the POSICAM(TM)
HZ and HZL.  In July 1993 the Company received FDA approval to market in the 
United States the POSICAM(TM) HZL, which has an even larger field of view than 
the POSICAM(TM) HZ facilitating whole body scanning and the scanning of large 
organs. As the market for PET systems matures and price sensitivity among 
purchasers increases, the Company believes that interest in the POSICAM(TM) HZ,
a low cost version of the POSICAM(TM) HZL, will increase(1).  The Company 
believes that the special features of the POSICAM(TM) HZL enhance its 
usefulness in oncology and neurology applications(1).

     CYCLOTRON DISTRIBUTION.   Since certain cardiac and all neurological and
oncological applications require the use of cyclotron processed
radiopharmaceuticals, the Company entered into a distribution agreement with
Oxford Instruments Inc. ("Oxford") to be its exclusive North American cyclotron
distributor.  Under the distribution agreement the Company is able to market,
install, service and maintain Oxford's cyclotrons.  The distribution agreement
gives Oxford the right to terminate the agreement at any time after March 1,
1994, if at that time the Company had not placed orders for at least two
cyclotrons.  As of that date, the Company had received only one order for a
cyclotron.  As a result, Oxford currently has the right to terminate the
distribution agreement upon written notice to the Company. As of March 15, 1997,
the Company has not received notice from Oxford indicating a desire to terminate
the distribution agreement.  The Company believes that if Oxford were to
terminate the distribution agreement, it could enter into comparable
distribution arrangements with other cyclotron manufacturers.(1)

CUSTOMER SERVICE AND WARRANTY

     The Company has eight (8) field service engineers located throughout the
United States, who have primary responsibility for supporting and maintaining
the Company's installed equipment base.  In addition, the field engineers are
involved in site planning, customer training, sales of hardware upgrades, sales
and administration of service contracts, telephone technical support and
customer service.

     The Company typically provides a one-year warranty to purchasers of a
POSICAM(TM) system.  However, in the past, the Company offered multi-year
warranties to facilitate sales of its systems.  Following the warranty period,
the Company offers purchasers a comprehensive service contract under which the
Company provides all parts and labor, system software upgrades and unlimited
service calls.  The service revenues to the Company under its standard service
contract range from approximately $120,000 to $200,000 per year.  The Company
currently provides service to all of its  POSICAM(TM) systems,  ten (10) of
which are under formal service contracts. One (1) of the service contracts is
automatically renewed on a month-to-month basis and one (1) automatically renews
on a year-to-year basis.  Of the remaining eight (8) service contracts,  three
(3) expire during 1997, four (4) expire in 1998, and one (1) expires in 1999.
The Company is currently negotiating to extend all of the service contracts
which expire in 1997; however, there are no assurances that such extension will
be obtained.

     The Company's service goal is to maintain maximum system up-time.  The
Company's service organization seeks to resolve problems within 24 hours of
receipt of a service call.  Success of a clinical site is largely dependent on
patient volume during normal working hours and therefore equipment uptime and
reliability are key factors in this success.  The average uptime for all
installed POSICAM(TM) systems during each of 1995 and 1996, was approximately
98%.

     The Company has established a program to train doctors, nurses and
technicians, many of whom are unfamiliar with PET imaging, in the operation of
the Company's system and in the interpretation of PET images.  In addition, the
Company has arrangements with physicians and nurses knowledgeable of the
Company's systems to provide training to physicians and nurses who will be
involved with newly installed systems.

COMPETITION

     The Company believes that PET technology is a cost-effective diagnostic
tool as compared to other imaging techniques.  The Company faces competition
from two (2) other commercial manufacturers of PET systems as well as from other
imaging technologies, primarily SPECT and MRI.  The Company does not believe
that MRI and CAT scan imaging represent significant competing technologies.  The
Company views MRI and CAT scan imaging to be complementary technologies to PET,
in that PET and MRI and CAT scans each provide information not available from
the other.

     The Company's primary competition comes from two major commercial
manufacturers of PET systems, General Electric Company ("GE") and Siemens
Medical Systems Inc.  ("Siemens") (in a joint venture with CTI, Inc.  of
Knoxville, Tennessee).  GE and Siemens have substantially greater financial,
technological and personnel resources than the Company.  See "Item 1.
Description of Business--Risk Associated with Business Activities--Substantial
Competition and Effects of Technological Change and General Electric
Transaction".  In addition, two Japanese manufacturers, Hitachi and Shimadzu,
have manufactured and sold PET scanners in Japan but not in the United States.
In general, the Company believes that the Japanese PET systems are not currently
competitive with the products of the Company and its two major United States
competitors.

     The Company believes that it is currently competitive in each of the
primary competitive factors in the PET cardiology market, which are scanner
performance (in terms of count rate sensitivity and "dead time"), the ability to
scan short half-life radiopharmaceuticals (in particular, those which are
generator produced and do not require the purchase of a cyclotron), user-
friendly, clinically-oriented computer software, equipment up-time and customer
service.

     Competition in the market for diagnostic imaging systems in general is
intense and is expected to increase.  The market is characterized by rapid
technological innovation in terms of enhancements in the PET industry as well as
improvements in competing technologies and the emergence of new technologies.
See "Item 1. Description of Business--Risk Associated with Business Activities--
Substantial Competition and Effects of Technological Change."

     The primary competing technology in the nuclear medicine industry is SPECT.
The Company believes that the primary reason that SPECT competes with PET is the
lower cost of the SPECT systems.  A SPECT system can cost between $175,000 and
$750,000 as compared with $1.0 million to $1.8 million (depending on
configuration and equipment options) for a POSICAM(TM) system.  However, the
Company believes its POSICAM(TM) systems are a better diagnostic tool in that
the Company's systems are able to create more accurate images than SPECT
imaging.  Unlike SPECT, the radioactive substances used by the Company's systems
are based on naturally occurring substances within the body and allow the
POSICAM(TM) systems to directly measure the metabolic processes and changes
occurring within the scanned organ, thus providing a more accurate image.  In
addition, unlike SPECT, POSICAM(TM) systems are able to correct for image
deficiencies created by absorption of photons by the body.  Additionally,
POSICAM(TM) systems have higher and more uniform resolution than SPECT imagers
allowing POSICAM(TM) systems to image smaller objects without blurring.
POSICAM(TM) systems, in addition to being more accurate, can complete a scan in
as little as 45 minutes, while SPECT may require as many as three separate scans
spaced over 24 hours.

     High field MRI technology, an advanced version of MRI, is in the
development stage, but is a potential competitor to PET in certain neurology and
oncology applications.  Presently, high field MRI may be useful in performing
certain research (non-clinical) applications such as blood flow studies to
perform "brain mapping" to localize the portions of the brain associated with
individual functions (such as motor activities and vision).  However, high field
MRI does not have the capability to assess metabolism.  The Company cannot
presently predict the future competitiveness of high field MRI.

     Several manufacturers of SPECT systems are now offering multi-head systems
which have been modified to operate in a coincidence mode, similar to a PET
scanner.  These systems achieve spatial resolutions similar to that of PET
scanners, but their sensitivity and count rate are only a small fraction of that
achieved by true PET scanners, making the images "noisy" and more difficult to
interpret.  The Company believes these systems are useful for only a very
limited class of clinical PET studies using only the FDG radio tracer(1).  In
addition, SPECT coincidence systems offer limited, if any, corrections for
patient attenuation and scatter, which affects the accuracy of diagnosis.  As a
result, the Company believes that there will be a very limited research market
for this type of coincidence imaging system(1).

THIRD-PARTY REIMBURSEMENT

     POSICAM(TM) systems are purchased or leased primarily by medical
institutions which provide health care services to their patients.  Such
institutions or patients typically bill or seek reimbursement from various
third-party payors such as Medicare, Medicaid, other governmental programs and
private insurance carriers for the charges associated with the provided
healthcare services.  The Company believes that the market success of PET
imaging depends largely upon obtaining favorable coverage and reimbursement
policies from such programs and carriers.

     MEDICARE/MEDICAID REIMBURSEMENT.   Prior to March 1995, Medicare and
Medicaid did not provide reimbursement for certain PET imaging.  Decisions as to
such policies for major new medical procedures are typically made by the U.S.
Health Care Financing Administration ("HCFA"), based in part on recommendations
made to it by the Office of Health Technology Assessment ("OHTA").
Historically, OHTA has not completed an evaluation of a procedure unless all of
the devices and/or drugs used in the procedure have received approval or
clearance for marketing by the FDA.  Decisions as to the extent of Medicaid
coverage for particular technologies are made separately by the various state
Medicaid programs, but such programs tend to follow Medicare national coverage
policies.

     In November 1989, OHTA commenced a review of PET imaging for cardiac scans
using the generator produced radiopharmaceutical, Rubidium-82.  This was
preceded in 1988 by the FDA's approval of Rubidium-82 for patient imaging.  In
1994 HCFA received OTHA's findings, and  began evaluating the final issues
relative to coverage of PET imaging utilizing Rubidium-82 for Medicare and
Medicaid reimbursement.  On March 23, 1995, the Company was informed that HCFA
advised the drug manufacturer, Bracco Diagnostics, Inc., of the decision to
reimburse Rubidium-82 for use as a PET myocardial perfusion imaging agent.

     Additional isotopes for PET imaging such as Fluro-Deoxy-Glucose ("FDG") are
waiting FDA approval.  FDG has been under review since 1991.  FDG is currently
prepared and administered under state regulations governing the practices of
pharmacy and medicine.  Since the individual states regulate the production of
FDG under their own laws, the drug cannot be transported across state lines
without FDA approval.

     In February 1995, the FDA announced that cyclotron based PET
radiopharmaceuticals such as FDG would be regulated under the provisions of the
Federal Food, Drug and Cosmetic act, which stipulates that new drugs must be the
subject of approved new drug applications ("NDA's") or abbreviated new drug
applications.  This regulation requires that a cyclotron facility must have FDA
approval before selling clinical radiopharmaceuticals for usage by PET
facilities.  The Company believes that most of the cardiac applications of its
POSICAM(TM) systems involve the use of Rubidium-82 which is produced by a
generator rather than manufactured by a cyclotron.  Therefore, the Company
believes that the announced regulations concerning cyclotron manufactured
radiopharmaceuticals will not have a significant impact upon cardiac
applications of its POSICAM(TM) systems.  However, as of March 15, 1997, the
Company is unable to predict the overall impact of the new regulations on other
applications of its POSICAM(TM) system which involve the use of cyclotron
manufactured radiopharmaceuticals.

     PRIVATE INSURER REIMBURSEMENT.   The Company estimates that there are 1,500
private third-party insurance carriers in the United States.  Most of these
carriers currently consider PET imaging to be an investigational procedure and
do not reimburse for procedures involving PET imaging.  In 1992, however, the
National Blue Cross and Blue Shield Association recommended that PET imaging be
covered for evaluation of radiotherapy and chemotherapy, and for selection of
patients for surgical excision of the source of uncontrollable epileptic
seizures.  State Blue Cross and Blue Shield plans in Nebraska, Iowa, California
and Florida have recently adopted official payment policies concerning PET
cardiology application.  Aetna and Foundation Health Plan of Sacramento now
cover oncologic, cardiac and neurologic PET imaging applications, and Lincoln
National Life Insurance Company has developed a national policy for coverage of
neurological PET imaging applications.  In addition, the Company believes that
approximately 650 private insurance carriers, while they do not have broad PET
reimbursement policies, reimburse for PET scans on a case-by-case basis.

     If third-party coverage for PET procedures using the POSICAM(TM) system
remains unavailable, it will likely have a material adverse effect on the
Company's business, financial condition and results of operations(1).
Certain federal health care reforms are currently being considered by Congress,
one of which would make cost effectiveness 

                                       9
<PAGE>
 
a criteria for Medicare and other third-party payor reimbursement.  At this 
time, the Company is unable to predict what additional legislation or 
regulation, if any, relating to the health care industry or third-party 
coverage and reimbursement may be enacted in the future or what effect such 
legislation or regulation would have on the Company(1).

MANUFACTURING

     The Company assembles its POSICAM(TM) scanners in a 7,000 square foot area
of its 30,000 square foot corporate facility located in Houston, Texas.
Scanners are generally produced by assembling parts furnished to the Company by
outside suppliers.  A typical POSICAM(TM) system can generally be assembled in
two months and requires one month of testing before delivery.

     An essential component of the Company's POSICAM(TM) systems is bismuth
germinate oxide ("BGO") crystals which detect the positron emissions forming the
basis for a PET image, and photomultiplier tubes, which convert the light energy
emitted by such crystals into electrical impulses for use in the image
reconstruction process.  BGO crystals are specially manufactured and are
available from a supplier located in the United States, that is a subsidiary of
a Japanese company and another supplier located in France.  While the Company
primarily relies on a single source for its BGO crystals, it has in the past
purchased crystals from the second manufacturer and believes that it could
resume such purchases at acceptable prices and without significant delays.  The
Company purchases photomultiplier tubes primarily from a French supplier.  In
the event that the supply of French photomultiplier tubes were to be
interrupted, the Company believes it has the ability to source similar product
from an alternate manufacturer in France(1).  The Company believes that
multiple vendor sources exist in the United States for all other parts, for
which no individual vendor is critical to production(1).

     The Company maintains an active quality-assurance program, which includes
manufacturing product in small lots, tracking all defects and failures,
conducting area meetings, and maintaining thorough documentation and a well-kept
facility.  Each assembler of a part is responsible for maintaining his or her
area of assembly and assuring that parts have been properly inspected and
tested.  The Company believes that it is in compliance with all government
regulations regarding the manufacturing of it POSICAM(TM) systems.

     The Company has not historically experienced a material production and
delivery backlog.  The Company currently has in place a production and delivery
system capable of producing and delivering up to three POSICAM(TM) systems per
month.  If the Company experienced a significant increase in the sales volume of
its POSICAM(TM) systems, the Company would be required to implement certain
modifications to its existing production and delivery systems.

RESEARCH AND DEVELOPMENT

     The Company's POSICAM(TM) systems are based upon proprietary technology
initially developed at the University of Texas Health Science Center ("UTHSC")
in Houston, Texas under a $24 million research program begun in 1979 and funded
by UTHSC and The Clayton Foundation for Research (the "Clayton Foundation"), a
Houston-based, non-profit organization.  Further product development and
commercialization of the system has been funded by the Company.

     The Company's research and development expenses for the years ended
December 31, 1995 and 1996 were $2,481,000 and $2,227,000, respectively.  In
addition to the Company's sponsored and funded research and development
programs, the Company in the past has supplemented its research and development
with a technology transfer agreement with UTHSC and currently is participating
in collaborative research efforts with selected clinical and research customers,
and research grants funded through the federal government's Small Business
Innovative Research ("SBIR") program.

     The Company intends to continue its research into new scintillator material
and detectors which is expected to focus on improving "dead-time" and
sensitivity.(1)  The Company also intends to investigate new electronics
configurations in order to improve the systems' performance and reduce the size
and cost of the scanners(1).  

                                       10
<PAGE>
 
Additionally, the Company intends to explore new computer architecture to 
reduce the systems' cost and reduce the scanning time per patient.(1)

     The Company has developed a neurology software analysis package with the
Yale/Veterans Administration PET Center to provide imaging tools for the
neurologist.  The Company intends to continue its cooperative development
efforts with leading research institutions to improve neurology and oncology
imaging(1).  The Company offers a clinical cardiology software package which
displays images and facilitates the diagnosis of coronary artery disease and
tissue viability.

     The Company has a continuing program of enhancing and improving its
software which is aided by its collaboration with practicing physicians and
researchers who provide technical and practical advice to the Company based upon
their clinical experiences with the POSICAM(TM) systems and efforts to improve
clinical procedures.  The Company has received input from clinical users and
research collaborators, and the Company is conducting research and development
on new software products.  The Company expects that this research and
development will result in new neurology and oncology analysis packages and
clinical computer protocols and improvements in data acquisition and image
reconstruction software(1).

PATENT AND ROYALTY ARRANGEMENTS

     The Company acquired the know-how and patent rights to positron imaging
(the "Licensed Technology") from the Clayton Foundation, K. Lance Gould (a
director of the Company) and Nizar A. Mullani (formerly a director of the
Company).  The Company is currently obligated to pay royalties of 3% of the
gross revenues from sales, uses, leases, licensing or rentals of the Licensed
Technologies, 1% to each of the Clayton Foundation, K. Lance Gould and Nizar A.
Mullani.

     Two of the Company's patents, issued in January 1986 and February 1987 and
expiring in January 2003 and February 2004, respectively, relate to the
staggered crystal array design of its POSICAM(TM) systems.  One additional
patent, issued in June 1987 and expiring June 2004, relates to technology which
the Company, by obtaining the patent, has reserved the right to use.  The
Company maintains certain of its patents in Germany and has applied for certain
patents in Japan.  In May 1993, the Company received an additional patent, that
expires in May 2010, relating to the innovative light guide and detector
staggering concepts used in its POSICAM(TM) HZ system.

     The Company seeks to protect its trade secrets and proprietary know how
through confidentiality agreements with its employees and consultants.  The
Company requires each employee and consultant to enter into a confidentiality
agreement containing provisions prohibiting the disclosure of confidential
information to anyone outside the Company, and requiring disclosure to the
Company of any ideas, developments, discoveries or investigations conceived
during employment or service as a consultant and the assignment to the Company
of patents and proprietary rights to such matters related to the business and
technology of the Company.


GOVERNMENT REGULATION

     The Company's POSICAM(TM) systems and the radiopharmaceuticals used in
connection with them are subject to regulation by the FDA.  The FDA regulates
and approves the clinical testing, manufacture, labeling, distribution and
promotion of medical devices in the United States prior to their
commercialization.  In addition, various foreign countries in which the
Company's products are or may be marketed, impose certain regulatory
requirements.

     The Company's POSICAM(TM) systems are regulated as medical devices by the
FDA and require premarket clearance by the FDA.  Pursuant to the Medical Device
Amendments of May 1976, the FDA classifies medical devices in commercial
distribution as a class I, class II, or class III device.  This classification
scheme is based on the controls necessary to reasonably ensure the safety and
effectiveness of the medical devices.  Class I devices are those devices whose
safety and effectiveness can reasonably be ensured through general controls,
such as adequate labeling, premarket notification and adherence to the Good
Manufacturing Practice ("GMP") regulations.  Class II devices are those devices
whose safety and effectiveness can reasonably be assured through the use of
special controls, such as 

                                       11
<PAGE>
 
performance standards, post market surveillance, patient registries and FDA 
guidelines.  Class III devices require premarket approval from the FDA and are 
generally devices which support or sustain human life or present a potential 
risk of illness or injury.  The POSICAM(TM) systems are considered to be class 
II devices.  However, as of March 15, 1997, the FDA has not promulgated a 
performance standard for PET systems.  Therefore, the POSICAM(TM) systems are 
not currently subject to such controls, nor are they subject to post market 
surveillance, patient registries and FDA guidelines.

     Before it can be commercially marketed L/C class II device must be approved
by the FDA.  If a medical device is "substantially equivalent" to a legally
marketed class II device, the manufacturer or distributor may seek FDA clearance
by filing what is known as a 510(k) premarket notification which must be
supported by data and test results.  If the FDA determines that the device is
substantially equivalent, then it may be marketed in the United States.  The FDA
may, however, require additional data or additional test results, or may
determine that a device is "not substantially equivalent."  Request for
additional data or test results or a "not substantially equivalent"
determination could delay the Company's market introduction of new products and
could have a material adverse effect on the Company's financial results and
operations(1).  The FDA is not required to respond to 510(k) premarket
notifications within a specific time period.  The FDA has recently began
requiring a more rigorous demonstration of substantial equivalence and in many
cases the time periods required for product approvals have increased.  If the
FDA determines that a new product is "not substantially equivalent," then the
manufacturer must undergo a lengthy Pre-Marketing Approval process which
generally involves clinical trials and submission of data to prove safety and
effectiveness before approval is granted.

     The Company's original POSICAM(TM) system received 510(k) clearance in
September 1985.  In November 1989, the Company was granted 510(k) clearance for
a modified POSICAM(TM) system, and also received approval for a mobile van
configuration.  In 1991, the Company applied for and received 510(k) clearance
of its POSICAM(TM) HZ system, and in July 1993 the Company received 510(k)
approval for the POSICAM(TM) HZL.

     The Company is also required to register as a medical device manufacturer
with the FDA.  As such, the Company may be inspected from time to time by the
FDA for compliance with the FDA's GMP regulations.  These regulations require
that the Company manufacture its products and maintain its documents in a
prescribed manner with respect to manufacturing, testing and control activities.
Further, the Company is required to comply with various FDA labeling
requirements.  The Medical Device Reporting regulation requires that the Company
provide information to the FDA on deaths or serious injuries alleged to have
been associated with the use of its devices, as well as product malfunctions
that would likely cause or contribute to death or serious injury if the
malfunction were to recur.  To date, no such deaths, injuries or product
malfunctions have occurred.  In addition, the FDA prohibits an approved device
from being marketed for unapproved applications.  To date the Company has not
received any notices of noncompliance from the FDA concerning GMP regulations.

     At the end of February 1995, the FDA conducted a GMP compliance inspection
at the Company's manufacturing facility.  As a result of that inspection in
April 1995, the Company received the first FDA warning letter in its operating
history.  Several issues were noted for corrective action in that letter.  The
Company has expeditiously taken action to address the FDA's concerns.  In
February 1996, the FDA began a follow-up inspection of the Company's corrective
actions.  As of March 15, 1997, the Company has not been informed of the result
of that inspection.  If the FDA finds that the Company has not corrected the
deficiencies noted in the warning letter it could, among other things, issue
another warning letter, prohibit new product introductions, institute a product
recall or prohibit the Company from shipping products until all deficiencies are
corrected to the FDA's satisfaction.  The Company is cooperating fully and
intends to continue to work with the FDA in all compliance matters.  In February
1997, the FDA began another routine inspection of the company's operating
facility.  As of March 15, 1997, the Company has not been informed of the
results of that inspection.

     The Company believes that it currently complies with all applicable
regulations regarding the manufacture and sale of medical devices, although such
regulations are subject to change and depend heavily on administrative
interpretations.  The Company also is subject to numerous federal, state and
local laws relating to such matters as safe working conditions, manufacturing
practices, fire hazard control, and disposal of hazardous or potentially
hazardous substances.

                                       12
<PAGE>
 
     The Company is required under Texas law to register with the Texas
Department of Health with respect to the Company's maintaining
radiopharmaceuticals on premises for testing and for research and development
purposes.  The Texas Department of Health has the authority to inspect the
Company's records and facilities to ensure compliance with these regulations.
The Company has in the past received notice of minor violations which have been
satisfactorily resolved with no punitive action.  The Company believes that
adequate measures have been taken to prevent their recurrence.

     Sales of medical devices outside of the United States may be subject to
foreign regulatory requirements that vary widely from country to country.  The
time required to obtain approval by a foreign country may be longer than that
required for FDA approval, and the requirements may differ.

     PET imaging centers must comply with regulations promulgated, in most
states, by an agency of the state government, under authority delegated by the
Nuclear Regulatory Commission governing the possession and use of
radiopharmaceuticals for medical diagnostic procedures.  In order to secure
approval, a PET imaging center must submit an acceptable site plan for its
scanner, employ adequate radiation safety and quality procedures, and provide a
nuclear physician who meets certain training and experience standards.
Cyclotrons are considered industrial devices and are therefore not covered by
any FDA regulations.  Currently, there are no state or federal regulations
concerning the sale, marketing, or ownership of cyclotrons.  However,
operational licenses are required by state radiation regulatory divisions.  The
licensing and/or registration of cyclotrons by a state is typically handled by
the state's Department of Health, Bureau of Radiation Control.

     Many states have "certificate of need" regulations that require a purchaser
or user of expensive diagnostic equipment such as PET systems to obtain
regulatory approval before it may purchase and install such equipment.  A
primary purpose of these regulations is to contain health costs by restricting
the number of similar units in a particular locality.  The Company has yet to
experience a situation where a customer was unable to obtain such approval.
However, restrictions of this nature may increase in the future through the
passage of legislation and the adoption of regulatory changes as a part of
overall health care reform.

BACKLOG

     The Company's backlog at December 31, 1996, consisted of purchase orders
for two POSICAM(TM) systems totaling approximately $2.1 million.  Additionally,
in January and February 1997, the Company received orders for four (4) systems.
The Company expects to deliver these systems during 1997.

PRODUCT LIABILITY AND INSURANCE

     Medical device companies are subject to a risk of product liability and
other liability claims in the event that the use of their products results in
personal injury claims.  The Company has not experienced any product liability
claims to date.  The Company maintains liability insurance with coverage of $2
million per occurrence and an annual aggregate maximum of $3 million.

EMPLOYEES

     As of March 15, 1997, the Company employed thirty-six (36) full-time
persons, twelve (12) are employed in the Company's engineering department,
eleven (11) in sales, marketing and field service, seven (7) in manufacturing
and six (6) in the executive and administration department.  The Company
believes that its relationship with its employees is satisfactory.

     On January 1, 1996, the Company entered into an employment agreement with
Werner J. Haas, Ph.D. pursuant to which Dr. Haas agreed to serve as President
and Chief Executive Officer of the Company for a term of two years.  The
employment agreement provided for the payment of an annual base salary of
$200,000, bonuses in an amount to be determined at the discretion of the Board
of Directors of the Company, and participation in any employee benefit plan
adopted by the Company for its employees.

                                       13
<PAGE>
 
     On February 18, 1997, Dr. Haas informed the Board of Directors of the
Company that he considered his contract to have been terminated by the Company
without cause as a result of the Company's failure to pay the February 15, 1997
payroll to any of its management level employees and specifically to him.  Dr.
Haas has demanded that the Company pay to him all past due salary as well as the
nine months severance pay specified in his employment agreement if his contract
is determined to have been terminated without cause. Additionally, Dr. Haas
resigned his position as a member of the Company's Board of Directors.  The
Company has indicated to Dr. Haas that it believes no amounts are due him under
his employment agreement.  As of March 15, 1997, the Company is unable to
predict the outcome of the disagreement between Dr. Haas and the Company.

     Gary B. Wood, Ph.D., currently Chairman of the Company's Board of
Directors, has assumed the duties of President and Chief Executive Officer until
selection of a replacement for Dr. Haas.

FORWARD LOOKING STATEMENTS.

     The Company's statements in the foregoing discussion not relating solely to
historical matters are forward looking statements and are based upon numerous
assumptions that could prove not to be accurate.  Accordingly, actual events and
results may materially differ from anticipated results .

RISKS ASSOCIATED WITH BUSINESS ACTIVITIES

     HISTORY OF LOSSES.  To date the Company has been unable to sell POSICAM(TM)
systems at quantities sufficient to be profitable.  Consequently, the Company
has sustained substantial losses.  Net losses for the years ended December 31,
1995 and 1996 were $5,028,000 and $6,375,000, respectively.  At December 31,
1996, the Company had an accumulated deficit of approximately $44,505,000.
There can be no assurance that the Company will ever achieve the level of
revenues needed to be profitable in the future or, if profitability is achieved,
that it will be sustained.  Due to the sizable sales price of each POSICAM(TM)
system and the limited number of systems that are sold or placed in service in
each fiscal period, the Company's revenues have fluctuated, and may likely
continue to fluctuate, significantly from quarter to quarter and from year to
year.

     WORKING CAPITAL DEFICIENCY.  At December 31, 1996, the Company had cash and
cash equivalents in the amount of $382,000 compared to $102,000 at December 31,
1995. During certain times in 1996 and the first quarter of 1997, the Company
has been unable to meet certain of its obligations as they came due.  As a
result of the Company's liquidity problem certain management level employees
have deferred payment of salaries through March 15, 1997 totaling $135,000.
Additionally, the Company is in arrears to many of its vendors and suppliers.
As of March 31, 1997, such amount owed to vendors and suppliers totaled
approximately $1,100,000.

     As a result of the Company's liquidity problems, its auditors, Coopers &
Lybrand, L.L.P., have added an emphasis paragraph to their opinion on the
Company's financial statements indicating that substantial doubt exists about
the Company's ability to continue as a going concern.  In conjunction with the
financing of the proposed acquisition of GE's PET assets and technology, the
Company anticipates that it will secure working capital financing totaling
approximately $7 million to fund its ongoing operations until such time as the
sales of its and GE's PET systems generate sufficient cash flow to fund
operations, however, no assurances can be given that the Company will
successfully complete such financing (See "Item 1.  Risk Associated with
Business Activities - General Electric Transaction").  It is the Company's
intention to utilize a portion of such working capital funds to significantly
reduce the level of its past due obligations to its employees, vendors and
suppliers.(1)  Additionally, the Company believes that it will reach cash flow
break-even at the point at which it is selling approximately fifteen (15)
systems per year, however no assurance can be given that the Company will ever
reach such break-even level of sales (1).   (See Item 6. "Management's
Discussion and Analysis or Plan of Operation--Liquidity and Capital Resources".)

     In the event that the Company is unable to complete its acquisition of GE's
PET assets and technology, it will be necessary for it to enhance its financial
position by means of raising capital by the sale of additional equity
securities, the placement of additional debt or increased sales of its
POSICAM(TM) systems.  Although the Company has been actively pursuing the above
financing alternatives in connection with its proposed acquisition of GE's PET
assets, no assurances can be given that the Company will be able to successfully
alleviate its current financial difficulties or that it will be able to continue
as a going concern in the absence of obtaining such financing.(1)

     The Company currently has no shares of Common Stock available for issuance
and all authorized shares have either been issued or reserved for issuance in
respect of outstanding options and warrants or convertible securities.  The lack
of such  available shares significantly restricts the Company's ability to raise
additional capital through the sale of equity securities.  The Company believes
that its shareholders will approve an increase in the number of authorized
common shares at its Annual Meeting; however, no assurance can be given that
such additional shares will be authorized in adequate time to allow the Company
to issue such equity securities.

     GENERAL ELECTRIC TRANSACTION.  In July 1996, the Company and General
Electric Company ("GE") entered into an Acquisition Agreement (the "Agreement"),
which initially expired on January 4, 1997, pursuant to which the Company agreed
to purchase a portion of GE's product line relating to the design, engineering
and manufacture of certain PET equipment and related cyclotron systems (the
"Business").  Under the terms of the Agreement, the Company agreed to (i)
purchase from GE all of the capital stock of its wholly-owned Swedish
subsidiary, and (ii) purchase or license from GE substantially all of its assets
which are used principally in the conduct of Business.  Additionally, the
Company and GE entered into a Sales and Marketing Agreement (the "Marketing
Agreement") pursuant to which, subject to the conditions and limitations set
forth therein, GE agreed to purchase on an exclusive basis, and the Company
agreed to supply to GE, 

                                       15
<PAGE>
 
certain PET equipment and related cyclotron systems (collectively the "PET 
Products").  The initial term of the Marketing Agreement was for five (5) years.
Subject to the conditions set forth therein, GE agreed that, during the initial
term of the Marketing Agreement, GE would not, directly or indirectly engage in
the design, engineering of manufacture of PET Products.

     In exchange for the sale by GE of the assets described above and the
capital stock of its Swedish subsidiary, as well as the performance by GE of its
obligations under the Marketing Agreement, the Company agreed to pay to GE cash
of $25 million, subject to certain specified adjustments.  Additionally, the
Company agreed to issue to GE a number of shares of its Common Stock (the
"Acquisition Stock") which, would equal 10% of the Common Stock outstanding
immediately after consummation of the acquisition and the issuance of the
Acquisition Stock, assuming conversion of all outstanding shares of the
Company's convertible preferred stock and related common stock purchase warrants
and the issuance and exercise of the GE Option (described below).  The Company
also agreed to issue to GE an option (the "GE Option") to purchase a number of
shares of Common Stock which, upon exercise and conversion into shares of the
Company's Common Stock, would equal 15% of the Common Stock outstanding
immediately after consummation of the acquisition and the issuance of the
Acquisition Stock, assuming conversion of all outstanding shares of the
Company's convertible preferred stock and the issuance, exercise and conversion
of the GE Option.  The GE Option was initially exercisable for three (3) years
at an exercise price of $4.25.  On January 4, 1997, GE and the Company agreed to
extend the expiration date of the Agreement until March 31, 1997.

     The acquisition is subject to the satisfaction or waiver of certain
conditions precedent, including the Company's procurement of financing upon
terms and conditions acceptable to the Company and the approval by the Company's
shareholders of certain terms of the acquisition, including the issuance of the
Acquisition Stock and GE Option.  Under certain circumstances, if the Agreement
is terminated and the termination is not due to a breach by GE of its
representations, warranties or covenants set forth in the Agreement the Company
is required to pay to GE a termination fee of $1.5 million if the Company enters
into certain specified transactions within two (2) years of the date of
termination of the Agreement.

     As of March 31, 1997, the Company has not obtained commitments for the
financing required to complete the acquisition, nor has it obtained shareholder
approval of the issuance of the Acquisition Stock, the GE Option or the
Agreement.  There is no assurance that the Company will be able to procure the
required financing or that it will be successful in obtaining shareholder
approval of the transaction.  Failure of the Company to close the acquisition of
the Business is likely to have a material adverse effect on the Company's
ability to continue as a going concern.  See "Item 1.  Description of Business -
Risk Associated with Business Activities" and "Item 6.  Management's Discussion
and Analysis or Plan of Operation - Liquidity and Capital Resources".

     Closing of the GE Acquisition did not occur on March 31, 1997, nor has GE
agreed to extend the Agreement beyond March 31, 1997.  On April 10, 1997, GE
informed the Company that it was exercising its right to terminate the Agreement
and that it will pursue other options for its PET business.  GE remains open to
discussing a transaction on revised terms, if and only if, (i) a prompt closing
and payment of the full purchase price are assured, (ii) the transaction
continues to make business sense for both parties, and (iii) all necessary
details can be agreed upon by the parties.  The Company and GE have no binding
agreement to proceed with these discussions, nor can any assurances be given
that if they do proceed, any workable agreement will be reached by the parties.

     NASDAQ SMALLCAP MARKET ELIGIBILITY AND MAINTENANCE REQUIREMENTS:  POSSIBLE
DELISTING OF SECURITIES FROM THE NASDAQ SYSTEM.  The Company's Common Stock is
currently listed on the Nasdaq SmallCap Market.  The Board of Governors of the
National Association of Securities Dealers, Inc. (the "NASD") has established
certain standards for the continued listing of a security on the Nasdaq SmallCap
Market.  The standards required for the Company to maintain such listing
include, among other things, that the Company have total capital and surplus of
at least $1,000,000.  As of December 31, 1996, the Company had a total capital
and surplus deficit of $658,000.  The Company does not currently meet the
minimum requirements necessary to maintain its NASDAQ stock market listing and
will not meet those requirements until such time as it is able to raise capital
by the sale of additional equity securities or increased sales of its
POSICAM(TM) systems.  There can be no assurances that the Company will ever meet
the capital and surplus requirements needed to maintain its Nasdaq SmallCap
Market System listing.

                                       16
<PAGE>
 
     In the event that the Company is unable to satisfy Nasdaq's maintenance
requirements, trading would be conducted in the "pink sheets" or the NASD's
Electronic Bulletin Board.  In the absence of the Common Stock being quoted on
the Nasdaq SmallCap Market, as the Company does not have $2,000,000 in net
tangible assets, trading in the Common Stock  would be covered by rules
promulgated under the Exchange Act for non-Nasdaq and non-exchange listed
securities.  Under such rules, broker/dealers who recommend such securities to
persons other than established customers and accredited investors must make a
special written suitability determination for the purchaser and receive the
purchaser's written agreement to a transaction prior to sale.  Securities are
exempt from these rules if the market price is at least $5.00 per share.  As of
March 14, 1997, the closing price of the Company's Common Stock was $2.093.

     The SEC has adopted regulations that generally define a penny stock to be
any equity security that has a market price of less than $5.00 per share,
subject to certain exceptions.  Such exceptions include, in general,  an equity
security listed on the Nasdaq Market and an equity security issued by an issuer
that has (i) net tangible assets of at least $2,000,000, if such issuer has been
in continuous operation for three years, (ii) net tangible assets of at least
$5,000,000, if such issuer has been in continuous operation for less than three
years, or (iii) average revenue of at least $6,000,000 for the preceding three
years.  Unless an exception is available, the regulations require the delivery,
prior to any transaction involving a penny stock, of a disclosure schedule
explaining the penny stock market and the risks associated therewith.

     If the Company's Common Stock was subject to the regulations on penny
stock, the market liquidity for the Common Stock would be severely affected by
limiting the ability of broker/dealers to sell the Common Stock in the public
market.  There is no assurance that trading in the Company's securities will not
be subject to these or other regulations that would adversely affect the market
for such securities.

     NASDAQ SHAREHOLDER APPROVAL REQUIREMENT.  In general, the rules governing
the listing of the Company's Common Stock on the Nasdaq SmallCap Market require
approval by the Company's Common Stockholders of any transaction, other than a
public offering, involving the sale or issuance by the Company of its Common
Stock, or securities convertible into or exercisable for Common Stock, at a
price less than the greater of book or market value, which equals more than 20%
of the issued and outstanding Common Stock.  Under ordinary circumstances, the
Company would have been required to obtain such shareholder approval before
proceeding with the Company's private placement of Series A Preferred Stock.
However, on February 9, 1996, the NASD granted the Company an exception to the
shareholder requirement.  In order to be entitled to receive the exception, the
Company's Board  of Directors, and the members thereof comprising the Company's
Audit Committee, determined that the delay in proceeding with the Company's
March, 1996 private placement of Series A Preferred Stock that would be
necessary in order to obtain the required shareholder approval would seriously
jeopardize the financial viability of the Company.  The exception granted by the
NASD required the Company to mail to all of its shareholders a letter alerting
the shareholders to the Company's omission in seeking the required shareholder
approval and that its Audit Committee has expressly approved the Company's
reliance on such exception.  The Company's reliance on such exception may have
an adverse affect on the public trading price of its Common Stock.

     DILUTION.  In connection with the issuance of the Series A and Series B
Preferred Stock, the Company issued 1,266,690 warrants which are convertible
into its Common Stock and warrants to purchase its Common Stock.  The exercise
of these warrants would be materially dilutive to the current issued and
outstanding shares of Common Stock.  As of March 15, 1997, a total of 4,168 of
these warrants have been exercised and converted into Common Stock of the
Company.

 
     SUBSTANTIAL COMPETITION AND EFFECTS OF TECHNOLOGICAL CHANGE.  The industry
in which the Company is engaged is subject to rapid and significant
technological change.  There can be no assurance that POSICAM(TM) systems can be
upgraded to meet future innovations in the PET industry or that new technologies
will not emerge, or existing technologies will not be improved, which would
render the Company's products obsolete or non-competitive.  The Company faces
competition in the United States PET market primarily from General Electric
Company and Siemens Medical Systems, Inc., two major commercial manufacturers,
each of which has significantly greater financial and technical resources and
production and marketing capabilities than the Company.  In addition, there can
be no assurance that other established medical concerns, any of which would
likely have greater resources than the Company, will not enter the market.  The
Company also faces competition from other imaging technologies which are more
firmly established and have a greater 

                                       17
<PAGE>
 
market acceptance, including single-photon emission computed tomography 
("SPECT").  There can be no assurance that the Company will be able to compete 
successfully against any of its competitors.

     NO ASSURANCE OF MARKET ACCEPTANCE.  The POSICAM(TM) systems involve new
technology that competes with more established diagnostic techniques.  The
purchase and installation of a PET system involves a significant capital
expenditure on the part of the purchaser.  A potential purchaser of a PET system
must have an available patient base that is large enough to provide the
utilization rate needed to justify such capital expenditure.  There can be no
assurance that PET technology or the Company's POSICAM(TM) systems will be
accepted by the target markets or that the Company's sales of POSICAM(TM)
systems will increase or that the Company will ever be profitable.

     PATENTS AND PROPRIETARY TECHNOLOGY.  The Company holds certain patent and
trade secret rights relating to various aspects of its PET technology, which are
of material importance to the Company and its future prospects.  There can be no
assurance, however, that the Company's patents will provide meaningful
protection from competitors.  Even if a competitor's products were to infringe
on patents held by the Company, it would be costly for the Company to enforce
its rights and the enforcement of its rights would divert funds and resources
from the Company's operations.  Furthermore, there can be no assurance that the
Company's products will not infringe any patents of others.

     The Company requires each employee and/or consultant to enter into a
confidentiality agreement, but there can be no assurance that these agreements
will provide meaningful protection or adequate remedies for the Company's trade
secrets or proprietary know-how in the event of unauthorized use or disclosure
of such information or that others will not independently develop substantially
equivalent proprietary information and techniques or otherwise gain access to
the Company's trade secrets and proprietary know-how.

     GOVERNMENT REGULATION.  The Company's POSICAM(TM) systems and the
radiopharmaceuticals used in connection with them are subject to regulation by
the FDA. The FDA regulates and must approve the clinical testing, manufacturing,
labeling, distribution and promotion of medical devices in the United States.
There can be no assurance that any additional product or enhancement that the
Company may develop will be approved by the FDA.  Delays in receiving regulatory
approval could have a material adverse effect on the Company's business.  In
addition, various foreign countries in which the Company's products are or may
be marketed impose additional regulatory requirements.  Further, the Company's
operations and the operations of users of PET systems are subject to regulation
under federal and state health and safety laws, and purchasers and users of PET
systems are subject to federal and state laws and regulations regarding the
purchase of medical equipment such as PET systems.  All laws and regulations,
including those specifically applicable to the Company, are subject to change.
The Company cannot predict what effect changes in laws and regulations might
have on its business.  Failure to comply with applicable laws and regulatory
requirements could have a material adverse effect on the Company's business,
financial condition, results of operations and cash flows.

     CERTAIN FINANCING ARRANGEMENTS.  In order to sell its POSICAM(TM) systems,
the Company has from time to time found it necessary to participate in ventures
with certain customers or otherwise assist customers in their financing
arrangements.  The venture arrangements have involved lower cash prices for the
Company's systems in exchange for interests in the ventures, thus exposing the
Company to the attendant business risks of the ventures.  The Company has, in
certain instances, sold its systems to financial intermediaries which have, in
turn, leased the systems to users.  Such transactions may not give rise to the
same economic benefit to the Company as would have occurred had the Company made
a direct cash sale at its normal market prices on normal sales terms.  There can
be no assurance that the Company will not find it necessary to enter into
similar transactions to effect future sales. The nature and extent of the
Company's interest in such ventures or the existence of remarketing or similar
obligations could require the Company to account for such transactions as
financing arrangements rather than "sales" for financial reporting purposes.
Such treatment could have the effect of delaying the recognition of revenue on
such transactions and may increase the volatility of the Company's financial
results.

     PRODUCT LIABILITY AND INSURANCE.  The use of the Company's products entails
risks of product liability.  There can be no assurance that product liability
claims will not be successfully asserted against the Company.  The Company
maintains liability insurance coverage in the amount of $2 million per
occurrence and an annual aggregate maximum of $3 million.  However there can be
no assurance that the Company will be able to maintain such insurance in the
future or, if maintained, 

                                       18
<PAGE>
 
that such insurance will be sufficient in amount to cover any successful 
product liability claims.  Any uninsured liability could have a material 
adverse effect on the Company.

     NO DIVIDENDS.  The Company has never paid cash dividends on its Common
Stock and  does not intend to pay cash dividends on its Common Stock in the
foreseeable future.  The Series A Preferred Stock and Series B Preferred Stock
Statements of Designation prohibit the payment of Common Stock dividends until
all required dividends have been paid on each series of preferred stock.  As of
December 31, 1996, approximately $185,000 of preferred stock dividends are
undeclared and unpaid by the Company.

Item 5.  MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS

     In December 1993, the Company completed an initial public offering of
1,750,000 shares of Common Stock and 1,946,775 redeemable warrants (the
"Redeemable Warrants") to purchase Common Stock (the "Initial Public Offering").
Prior to the Initial Public Offering there was no public market for the
Company's Common Stock.  The Company's Common Stock and Redeemable Warrants are
currently traded on the Nasdaq SmallCap Market under the symbols POSI and POSIW,
respectively.  See "Item 1.  Description of Business -- Risks Associated with

     There were approximately 250 holders of record of shares of Common Stock as
of March 15, 1997.  The Company estimates that there were also approximately 800
beneficial holders of Common Stock as of March 15, 1997.

     The Company has never paid cash dividends on its Common Stock.  The Company
does not intend to pay cash dividends on its Common Stock in the foreseeable
future.  The Series A Preferred Stock and Series B Preferred Stock Statements of
Designation prohibit the payment of Common Stock dividends until all required
dividends have been paid on each series of preferred stock.  As of December 31,
1996, approximately $185,000 of preferred stock dividends are undeclared and
unpaid by the Company.

Item 6.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

GENERAL

     The Company was incorporated in December 1983 and commenced commercial
operations in 1986.  Since that time,  the Company has  generated  revenues
primarily from  the sale and service  of  the  Company's POSICAM(TM) systems.
To date, the Company has sold 20 POSICAM(TM) systems; 15 of which are currently
in operation in leading medical facilities in the United States.  In addition
the Company has sold and installed two (2) POSICAM(TM) system internationally.
Three (3) systems are no longer operational.  Of the 15 POSICAM(TM) systems
currently operating in the United States, nine (9) are in use at sites which are
primarily dedicated to clinical cardiology, one (1) is primarily dedicated to
oncology and five (5) are in use at multi-disciplinary research/clinical sites.

     GENERAL ELECTRIC TRANSACTION.  In July 1996, the Company and General
Electric Company ("GE") entered into an Acquisition Agreement (the "Agreement"),
which initially expired on January 4, 1997, pursuant to which the Company agreed
to purchase a portion of GE's product line relating to the design, engineering
and manufacture of certain PET equipment and related cyclotron systems (the
"Business").  Under the terms of the Agreement, the Company agreed to (i)
purchase from GE all of the capital stock of its wholly-owned Swedish
subsidiary, and (ii) purchase or license from GE substantially all of its assets
which are used principally in the conduct of Business.  Additionally, the
Company and GE entered into a Sales and Marketing Agreement (the "Marketing
Agreement") pursuant to which, subject to the conditions and limitations set
forth therein, GE agreed to purchase on an exclusive basis, and the Company
agreed to supply to GE, certain PET equipment and related cyclotron systems
(collectively the "PET Products").  The initial term of the Marketing 

                                       20
<PAGE>
 
Agreement was for five (5) years.  Subject to the conditions set forth therein,
GE agreed that, during the initial term of the Marketing Agreement, GE would 
not, directly or indirectly engage in the design, engineering of manufacture of
PET Products.

     In exchange for the sale by GE of the assets described above and the
capital stock of its Swedish subsidiary, as well as the performance by GE of its
obligations under the Marketing Agreement, the Company agreed to pay to GE cash
of $25 million, subject to certain specified adjustments.  Additionally, the
Company agreed to issue to GE a number of shares of its Common Stock (the
"Acquisition Stock") which, would equal 10% of the Common Stock outstanding
immediately after consummation of the acquisition and the issuance of the
Acquisition Stock, assuming conversion of all outstanding shares of the
Company's convertible preferred stock and related common stock purchase warrants
and the issuance and exercise of the GE Option (described below).  The Company
also agreed to issue to GE an option (the "GE Option") to purchase a number of
shares of Common Stock which, upon exercise and conversion into shares of the
Company's Common Stock, would equal 15% of the Common Stock outstanding
immediately after consummation of the acquisition and the issuance of the
Acquisition Stock, assuming conversion of all outstanding shares of the
Company's convertible preferred stock and the issuance, exercise and conversion
of the GE Option.  The GE Option was initially exercisable for three (3) years
at an exercise price of $4.25.   On January 4, 1997, GE and the Company agreed
to extend the expiration date of the Agreement until March 31, 1997.

     The acquisition is subject to the satisfaction or waiver of certain
conditions precedent, including the Company's procurement of financing upon
terms and conditions acceptable to the Company and the approval by the Company's
shareholders of certain terms of the acquisition, including the issuance of the
Acquisition Stock and GE Option.  Under certain circumstances, if the Agreement
is terminated and the termination is not due to a breach by GE of its
representations, warranties or covenants set forth in the Agreement the Company
is required to pay to GE a termination fee of $1.5 million if the Company enters
into certain specified transactions within two (2) years of the date of
termination of the Agreement.

     As of March 31, 1997, the Company had not obtained commitments for the
financing required to complete the acquisition, nor has it obtained shareholder
approval of the issuance of the Acquisition Stock, the GE Option or the
Agreement.  There is no assurance that the Company will be able to procure the
required financing or that it will be successful in obtaining shareholder
approval of the transaction.  Failure of the Company to close the acquisition of
the Business is likely to have a material adverse effect on the Company's
ability to continue as a going concern.  See "Item 1.  Description of Business -
Risk Associated with Business Activities" and "Item 6.  Management's Discussion
and Analysis or Plan of Operation - Liquidity and Capital Resources".

     On April 10, 1997, GE informed the Company that it was exercising its right
to terminate the Agreement and that it will pursue other options for its PET
business.  GE remains open to discussing a transaction on revised terms, if and
only if, (i) a prompt closing and payment of the full purchase price are
assured, (ii) the transaction continues to make business sense for both parties,
and (iii) all necessary details can be agreed upon by the parties.  The Company
and GE have no binding agreement to proceed with these discussions, nor can any
assurances be given that if they do proceed, any workable agreement will be
reached by the parties.

RESULTS OF OPERATIONS

     YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995.
Total revenue decreased $1,752,000 or 32.9% from $5,327,000 for the year ended
December 31, 1995 to $3,575,000 for the year ended December 31, 1996.

     Revenue from system sales decreased from $3,310,000 for 1995, to $650,000
for the same period in 1996, a decrease of $2,660,000 or 80.4%.  Included in
1996 results is a sale of a refurbished system at $650,000 compared to 1995
which included three sales of the HZ series systems.

     In the third quarter of 1995, the Company shipped its first system under a
fee-per-scan contract.  This system was installed and operable in the fourth
quarter of 1995.  Under the terms of the contract, the Company retains 

                                       21
<PAGE>
 
ownership to the POSICAM(TM) system and recognizes revenue based on the number 
of patients scanned on a daily basis.  Fee-per-scan revenue for 1996 was 
$415,000 compared to $68,000 in 1995.

     Service revenue increased $561,000 or 28.8% from $1,949,000 for the year
ended December 31, 1995, to $2,510,000 for the 1996 period.  The increase was
attributable to the booking of a system upgrade of $750,000 in 1996, offset by
two service contracts which were not renewed in 1996 as well as reductions in
the price of certain other service contracts.

     Gross profit in 1996 was $1,477,000 compared to $1,859,000 for 1995, a
decrease of $382,000 or 20.5%.  The decrease in gross profit resulted from a
$1,000,000 non-recurring warranty reserve booked in the first quarter of 1996 in
anticipation of possible losses to be incurred on the exchange of a scanner,
explained below, and a reduction in gross profit due to three HZ sales in the
1995 period versus the sale of a refurbished system in 1996.  These decreases
were offset by an increase of $750,000 for the system upgrade mentioned above,
the cost of which was booked in the fourth quarter of 1995, and an increase in
gross profit of $201,000 for the fee-per-scan system in 1996 as compared to
1995.

     The Company was notified by the customer who purchased the initial
production model HZL series scanner that the scanner was not performing to
certain of the contracted for specifications.  These specifications are higher
than those customarily provided to purchasers of the HZL scanner.  Additionally,
the scanner has experienced certain reliability problems related to detector
module failures which are currently being corrected by the Company.  The Company
has agreed with the customer to replace the scanner with a new scanner if it is
unable to bring the existing scanner up to the contracted specification.  If
necessary, the Company anticipates that the defective scanner will be replaced
in mid-1997.  If the replacement scanner does not meet the contracted
specifications, the customer could, among other things, return the system and
demand a full refund of the approximate net purchase price of $1,500,000; or,
request a discount (partial refund) from the contracted purchase price.  In
anticipation of the potential losses to be realized in correcting these problems
the Company increased its reserve for replacement of the scanner by $1 million
in the first quarter of 1996.

     Total operating expense increased $659,000 or 9.6% from $6,831,000 for the
year ended December 31, 1995, to $7,490,00 for the same period in 1996.

     Research and development expense decreased $254,000 or 10.2% from
$2,481,000 in 1995 to $2,227 in 1996,  principally due to reduced personnel and
program material costs.

     Selling and marketing expense decreased $453,000 or 29.8% from $1,518,000
for the year ended December 31, 1995, to $1,065,000 for the same period in 1996.
The decrease is due principally to lower sales commissions in 1996 versus 1995
combined with a reduction in the number of sales and marketing personnel.

     General and administrative expense increased $1,366,000 or 48.2% from
$2,832,000 in 1995 to $4,198,000 for the same 1996 period.  The increase is
attributable to an increase in the reserve for doubtful accounts of
approximately $760,000, as well as increased professional fees, property taxes
and public relations costs.  The Company's sales contract with the University of
Madrid requires payment to the Company based upon the number of clinical scans
performed at the PET center.  To date, the Company has received payment of
approximately $188,000 upon shipment of the scanner and has not received any
additional payments on the University's account.  In anticipation of the
possibility that the $813,000 balance owed by the University of Madrid would not
be paid, the Company increased its allowance for doubtful accounts for the
Madrid system to approximately $813,000 in the fourth quarter of 1996.

     Other income and (expense) increased $306,000, or 546.4% from ($56,000) in
1995 to $362,000 in 1996.  The increase resulted principally from interest
expense exceeding interest income as a result of the Company's short-term
borrowing to finance its operations as well as significantly lower invested
excess cash.

     As a result of the above reasons, the Company's loss increased 26.8% or
$1,347,000 from $5,028,000 in 1995 to $6,375,000 in 1996.

     YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994.
Total revenue for the year ended December 31, 1995 was $5,327,000 a decrease of
$754,000 or 12.4% from $6,081,000 for the year ended December 31, 1994.

     Revenue from system sales decreased $690,000 or 17.3% from $4,000,000 in
1994 compared to $3,310,000 in 1995.  Revenue for 1994 included approximately
$2,000,000 related to the sale of a cyclotron and $1,900,000 related to the sale
of one POSICAM(TM) system.  Revenue for 1995 included three POSICAM(TM) system
sales with an average selling price of approximately $1,100,000 each.

     In the second quarter of 1995, the Company shipped its first POSICAM(TM)
system under a fee per scan contract.  Under the terms of the contract, the
Company retains ownership to the POSICAM(TM) system and recognizes revenue and
cost based upon the number of patients scanned on a monthly basis.   Fee per
scan revenue was $68,000 in 1995 compared to $0 in 1994.  (See "Item 1.
Description of Business--Risk Associated with Business Activities--Certain
Financing Arrangements.")

     Service revenue in 1995 was $1,949,000, a decrease of $132,000 or 6.3% from
the 1994 total of $2,081,000.  The decrease was principally due to the non-
renewal of two service contracts  included in 1994 being offset by one new
contract for which the service revenue period began in January, 1995.

     Gross profit decreased from $2,664,000 in 1994 to $1,859,000 in 1995, a
decrease of 30.2% or $805,000.  The decrease is principally attributable to the
lower average system selling prices.

     Operating expense increased $108,000 or 1.6% from $6,723,000 in 1994 to
$6,831,000 in 1995.  The increase was principally attributable to increased
emphasis placed on various marketing programs in 1995 and increased selling
costs in 1995 offset by lower research and development costs.

     Research and development expenditures decreased $196,000 or 7.3% from
$2,677,000 in 1994 to $2,481,000 in 1995. The decrease was due to a special one-
time compensation payment made in 1994 as well as two research grants awarded in
1994 which were not present in 1995 being offset by increased labor costs in
1995 related to research and development of the Company's HZ series POSICAM(TM)
system.

     Selling and marketing expense increased by 19.5% or $248,000 to $1,518,000
in 1995, from $1,270,000 in 1994.  The increase was principally due to stronger
emphasis placed on various marketing programs, including market analysis of
changes in the managed care portion of the health care industry.  Additionally,
sales commissions and travel related to additional system sales increased in
1995 over 1994.

     General and administrative expense increased 2.0% or $56,000, from
$2,776,000 in 1994 to $2,832,000 in 1995.  The increase was principally due to
higher general and administrative salaries in 1995 as well as increased
manufacturing administrative costs, offset by a decrease in the 1995
compensation accrual.

     Other income and (expense) increased $354,000 from income of $298,000 in
1994 to an expense of $56,000 in 1995.  The increase resulted principally from
interest expense exceeding interest income as a result of the Company's need to
borrow short-term funds to finance its operations as well as significantly lower
invested excess cash.

     As a result of the above reasons, the Company's loss increased 33.7% or
$1,267,000 from $3,761,000 in 1994 to $5,028,000 in 1995.

NET OPERATING LOSS CARRYFORWARDS

     The Company has accumulated a significant net operating loss carryforward
which may be used to reduce taxable income and related income taxes in future
years.  Since the closing of the Company's 1993 initial public offering and the
sale in February,  March and May of 1996 of 3,075,318 Shares of Series A
Convertible Preferred Stock, each resulted in more than a 50% change in the
ownership percentages of shareholders, the provisions of Section 382 of the
Internal Revenue Code severely limit the annual utilization of the net operating
loss carryforwards.  In 

                                       23
<PAGE>
 
addition, the utilization of the losses to reduce future income taxes is 
dependent upon the generation of sufficient taxable income prior to the 
expiration of the net operating loss carryforwards.  The carryforwards will 
begin to expire in the year 1999.


LIQUIDITY AND CAPITAL RESOURCES

     Since its inception the Company has been unable to sell its POSICAM(TM)
systems in sufficient quantities to be profitable.  Consequently, the Company
has sustained substantial losses.  Net losses for the years ended December 31,
1996 and 1995 were $6,375,000 and $5,028,000, respectively.  The Company had an
accumulated deficit of $44,505,000 at December 31, 1996.  Due to the sizeable
selling prices of the Company's systems and the limited number of systems sold
or placed in service  each year, the Company's revenues have fluctuated
significantly year to year.

     At December 31, 1996, the Company had cash and cash equivalents in the
amount of $382,000 compared to $102,000 at December 31, 1995. During certain
times in 1996 and the first quarter of 1997, the Company has been unable to meet
certain of its obligations as they came due.  As a result of the Company's
liquidity problem certain management level employees have deferred payment of
salaries through March 15, 1997 totaling $135,000.  Additionally, the Company is
in arrears to many of its vendors and suppliers.  As of March 31, 1997, such
amount owed to vendors and suppliers totaled approximately $1,100,000.   This
amount excludes the nine months severance demand made by Dr. Haas.  See comments
under Employees above.

     As a result of the Company's liquidity problems, its auditors, Coopers &
Lybrand, L.L.P., have added an explanatory paragraph to their opinion on the
Company's financial statements indicating that substantial doubt exists about
the Company's ability to continue as a going concern.  In conjunction with the
financing of the proposed acquisition of GE's PET assets and technology, the
Company anticipates that it will secure working capital financing totaling
approximately $7 million to fund its ongoing operations until such time as the
sales of its and GE's PET systems generate sufficient cashflow to fund
operations, however, no assurances can be given that the Company will
successfully complete such financing (See "Item 1.  Risk Associated with
Business Activities - General Electric Transaction").  It is the Company's
intention to utilize a portion of such working capital funds to significantly
reduce the level of its past due obligations to its employees, vendors and
suppliers.(1)  Additionally, the Company believes that it will reach cashflow
break-even at the point at which it is selling approximately fifteen (15)
systems per year, however no assurance can be given that the Company will ever
reach such break-even level of sales(1).

     Due to its current liquidity problems, the Company currently is unable to
fulfill its commitment to manufacture the systems in its order backlog.  As
mentioned above, the Company believes that it will be successful in securing the
working capital necessary to fund the manufacture of these orders.

     In the event that the Company is unable to complete its acquisition of GE's
PET assets and technology, it will be necessary for it to enhance its financial
position by means of raising capital by the sale of additional equity
securities, the placement of additional debt or increased sales of its
POSICAM(TM) systems.  Although the Company has been actively pursuing the above
financing alternatives in connection with its proposed acquisition of GE's PET
assets, no assurances can be given that the Company will be able to successfully
alleviate its current financial difficulties or that it will be able to continue
as a going concern in the absence of obtaining such financing.(1)

     The Company currently has no shares of Common Stock available for issuance
and all authorized shares have either been issued or reserved for issuance in
respect of outstanding options and warrants or convertible securities.  The lack
of such  available shares significantly restricts the Company's ability to raise
additional capital through the sale of equity securities.  The Company believes
that its shareholders will approve an increase in the number of authorized
common shares at its Annual Meeting; however, no assurance can be given that
such additional shares will be authorized in adequate time to allow the Company
to issue such equity securities.

     Prior to the issuance of Series A Preferred Stock in February and  March
1996, discussed below, the Company also experienced significant liquidity
problems and was unable to pay certain of its obligations within their standard
terms.  As such the Company borrowed a total of $1,313,000 during the last
fiscal quarter of 1995 and first quarter of 1996 from Uro-Tech, Ltd., ("Uro-
Tech")  an affiliate of the Company, discussed below.

     URO-TECH LOAN.  During the last quarter of 1995 and the first quarter of
1996, in order to fund its activities, the Company borrowed a total of
$1,313,000 from Uro-Tech, Ltd.,  (the "Uro-Tech Loan").  The Uro-Tech Loan, as
amended, bears interest at 13.8% per annum and matures on March 31, 1997.  On
March 31, 1997, Uro-Tech agreed to an extension of the loan agreement until
April 30, 1997; all other terms and conditions of the agreement remain
unchanged.  The Uro-Tech Loan is collateralized by liens and security interests
encumbering most of the Company's assets including the Company's know-how,
patents and proprietary rights pertaining to its PET technology.  In connection
with the loan from Uro-Tech, the Company granted Uro-Tech warrants to purchase
67,500 shares of Common Stock, at an exercise price of $2.00 per share
exercisable through February 7, 2001.  The Company anticipates that the Uro-Tech
Loan will be repaid with a portion of the proceeds of the funding of the
acquisition of the PET assets and tecnology of GE.(1)

     BF&E LOAN.  On February 7, 1996, the Company entered into a lending
facility with Boston Financial & Equity Corporation pursuant to which the
Company may borrow up to 80% of its outstanding qualified accounts receivable
(the "BF&E Loan").  The maximum amount available under the BF&E Loan is
$1,000,000 and the BF&E Loan is collateralized by liens and security interests
encumbering most of the Company's assets including the Company's know-how,
patents and proprietary rights pertaining to its PET technology.  As of March
14, 1997 the available borrowing capacity under the BF&E Loan was approximately
$213,000 and $213,000 was outstanding under the BF&E Loan.  The BF&E Loan, as
amended, bears interest at 13.8% per year and matures on March 31, 1997.  On
March 31, 1997, BF&E agreed to an extension of the loan agreement until April
30, 1997, all other terms and conditions of the agreement remain unchanged.  In
connection with the BF&E Loan, the Company granted warrants to BF&E to purchase
45,000 shares of Common Stock, at an exercise price of $2.00 per share
exercisable through February 7, 2001.  The warrants contain standard anti-
dilution provisions and registration rights with respect to the shares of Common
Stock issuable upon the exercise thereof.  The Company anticipates that he BF&E
Loan will be repaid with a portion of the proceeds of the funding of the
acquisition of the PET assets and technology of GE.(1)

     PRIVATE PLACEMENT OF SERIES A PREFERRED STOCK.  In February, March and May
of 1996, the Company issued 3,075,318 shares of Series A 8% Cumulative
Convertible Redeemable Preferred Stock $1.00 par value ("Series A Preferred
Stock") and Redeemable Common Stock Purchase Warrants to purchase 1,537,696
shares of the Company's Common Stock.  The net proceeds of the private placement
were approximately $2,972,000.  Each share of the Series A Preferred Stock is
immediately convertible into one share of Common Stock.  Each Redeemable Common
Stock Purchase Warrant is exercisable at a price of $2.00 per share of Common
Stock.  As a result of the private placement of Series A Preferred Stock, the
Company currently does not have any available authorized shares of Common Stock
available for issuance.

     In conjunction with the issuance of the aforementioned Series A Preferred
Stock, Uro-Tech, converted $650,000 of the amount payable to it into 433,329
shares of Series A Preferred Stock and 216,671 Redeemable Stock Purchase
Warrants.

     PRIVATE PLACEMENT OF SERIES B PREFERRED STOCK.  In July 1996, the Company
issued 25,000 shares of Series B 8% Cumulative Convertible Redeemable Preferred
Stock $1.00 par value ("Series B Preferred Stock") and Common Stock Purchase
Warrants to purchase up to 100,000 shares of its Common Stock, par value $.01
per share.  The Series B Preferred Stock plus Common Stock Purchase Warrants
sold for approximately $50.00 per share of series B Preferred Stock.  Subject to
adjustment for certain antidilution events, each share of Series B Preferred
Stock is initially convertible into 25 shares of Common Stock and each Common
Stock Purchase Warrant is exercisable for one share of Common Stock at an
exercise price of $2.00 per share.  Each share of the Series B Preferred Stock
has a liquidation preference of $50.00 and is junior to the outstanding Series A
Preferred Stock.  The Series B Preferred Stock and the Common Stock Purchase
Warrants are not convertible or exercisable until such time as the Company's
shareholders approve an amendment to its Articles of Incorporation increasing
the amount of the authorized Common Stock by at lease 2,500,000 shares.

                                       25
<PAGE>
 
     Both of the Series A and Series B Preferred Stocks contain restrictions on
the payment of dividends on the Company's Common Stock.

     PROFUTURES LOAN.  On November 14, 1996, in order to fund its activities,
the Company obtained a loan facility of $1,400,000 from ProFutures Bridge
Capital, L.P. (The "ProFutures Loan").  The ProFutures Loan bears interest at a
rate of 12% until April 1, 1997, at which time the rate increases to 15%.  If
any debt remains outstanding after November 30, 1997, the interest rate will
increase to 18% per annum.  The ProFutures Loan is secured by liens and security
interest encumbering all of the assets of the Company, including know-how,
patents and proprietary rights pertaining to its PET technology.  In addition,
the Company granted ProFutures Bridge Capital, L.P. a ten year warrant to
purchase 250,000 shares of its common stock at an exercise price of $2.40 per
share.  Since the ProFutures Loan was not repaid on or before April 1, 1997,
the Company was required to grant to ProFutures additional warrants for the
purchase of an additional 100,000 shares of its common stock.  The exercise
price of such additional warrants was determined based upon the average closing
trading price for the Company's common stock for the ten (10) trading days prior
to April 1, 1997, which was $1.91.  The Company anticipates that the ProFutures
Loan will be repaid with a portion of the proceeds of the funding of the
acquisition of the PET assets and technology of GE.(1)

HEALTH CARE REFORMS

     The Company believes that expansion of the use of PET will ultimately
depend upon favorable coverage and reimbursement policies by Medicare, Medicaid
and third party medical insurance companies.  The Company believes that these
reimbursement policies will likely be influenced by the current movement towards
health care reform.(1)

FUTURE TRENDS

     The Company believes that as the market for PET systems matures,
competition among the manufacturers of PET systems will force the price of PET
systems down.(1)  The Company intends to continue its program of value
engineering, which is designed to reduce the Company's cost of manufacturing a
PET system.(1)  The Company believes that the average cost of producing a PET
system will decrease as volume increases.(1)  The Company also believes that
through a value engineering program and other cost reductions, it will be able
to maintain its current gross margins on sales of its systems.(1)  However,
there can be no assurance that the Company can maintain its gross margin in the
face of increasing price pressures.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

     In March 1997, the Financial Accounting Standards Board ("FASB") issued
SFAS No. 128, Earnings Per Share, which establishes specific computation,
--------------------------------                                         
presentation and disclosure requirements for earnings per share of entities with
publicly held common stock or potential common stock in order to simplify the
computation of earnings per share and make it compatible with the standards of
other countries and with that of the International Standards committee.  SFAS
128 is effective for financial statements of both interim and annual periods
ending after December 15, 1997.

     In March 1996, the FASB issued SFAS No. 129, Disclosure of Information
                                    ---------------------------------------
about Capital Structure, which applies to all entities and is effective for
-----------------------                                                    
financial statements for periods ending after December 15, 1997.

     The Company is currently evaluating its alternatives under SFAS No. 128 and
SFAS No. 129; however, their impact on operating results when initially adopted
is expected to be immaterial.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS



Board of Directors and Stockholders
Positron Corporation:


We have audited the accompanying balance sheets of Positron Corporation as of
December 31, 1995 and 1996 and the related statements of operations,
shareholders' equity (deficit) and cash flows for the years then  ended.  These
financial statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

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

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern.  As discussed in Note 1 to the
financial statements, the Company has suffered recurring losses from operations
and has a net capital deficiency that raises substantial doubt about its ability
to continue as a going concern.  Management's plans in regard to these matters
are also described in Note 1.  The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS



1.  DESCRIPTION OF BUSINESS:

Positron Corporation (the "Company") was incorporated on December 20, 1983, in
the State of Texas and commenced commercial operations during 1986.  The Company
designs, manufactures, markets and services its POSICAM(TM)  systems, advanced
medical imaging devices, utilizing positron emission tomography ("PET")
technology.  These systems utilize the Company's patented and proprietary
technology, an imaging technique which assesses the biochemistry, cellular
metabolism and physiology of organs and tissues, as well as producing anatomical
and structural images.  Targeted markets include medical facilities and
diagnostic centers located throughout the world. POSICAM(TM) systems are used by
physicians as diagnostic and treatment evaluation tools in the areas of
cardiology, neurology and oncology. The Company faces competition principally
from two other companies which specialize in advanced medical imaging equipment.

Since its inception the Company has been unable to sell its POSICAM(TM) systems
in sufficient quantities to be profitable. Consequently, the Company has
sustained substantial losses.  Net losses for the years ended December 31, 1996
and 1995 were $6,375,000 and $5,028,000, respectively.  The Company had an
accumulated deficit of $44,505,000 at December 31, 1996.  Due to the sizeable
selling prices of the Company's systems and the limited number of systems sold
or placed in service  each year, the Company's revenues have fluctuated
significantly year to year.

At December 31, 1996, the Company had cash and cash equivalents in the amount of
$382,000 compared to $102,000 at December 31, 1995. During certain times in 1996
and the first quarter of 1997, the Company has been unable to meet certain of
its obligations as they came due.  As a result of the Company's liquidity
problem, certain management level employees have deferred payment of first
quarter 1997 salaries through March 15, 1997 totaling approximately $135,000.
Additionally, the Company is in arrears to many of its vendors and suppliers. As
of March 15, 1997, such amount owed totaled approximately $1,100,000.   In
conjunction with the financing of the proposed acquisition of General Electric
Company's ("GE") PET assets and technology (see Note 12), the Company
anticipates that it will obtain working capital financing sufficient for it to
fund its ongoing operations until such time as the sales of its and GE's PET
systems generate sufficient cashflow to fund operations. It is the Company's
intention to utilize a portion of such working capital funds to significantly
reduce the level of its past due obligations to its employees, vendors and
suppliers.

In the event that the Company is unable to complete its acquisition of GE's PET
assets and technology, it will be necessary for it to enhance its financial
position by means of raising capital by the sale of additional equity
securities, the placement of additional debt or increased sales of its
POSICAM(TM) systems.  Although the Company has been actively pursuing the above
financing alternatives in connection with its proposed acquisition of GE's PET
assets, no assurances can be given that the Company will be able to successfully
alleviate its current financial difficulties. Failure of the Company to close
the aforementioned acquisition or obtain an alternate source of capital is
likely to have a material adverse effect on the Company's ability to continue as
a going concern.

Additionally, the Company currently has no shares of its Common Stock available
for issuance and all authorized shares have either been issued or reserved for
issuance in respect of outstanding options and warrants or convertible
securities. The lack of such available shares significantly restricts the
Company's ability to raise capital through the issuance of additional equity
securities.  While the Company believes that its shareholders will approve an
increase in the number of authorized shares of Common Stock at its Annual
Meeting of Shareholders, no assurance can be given that such increase in
authorized shares will be approved by the Company's shareholders.


2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

                                      F-7
<PAGE>
 
Cash and Cash Equivalents

Cash and cash equivalents include all cash balances and highly liquid
investments with an original maturity of three months or less.   The Company
invests in a fund with a high-credit quality financial institution. The
institution invests the funds in governmental securities, repurchase agreements
and money market funds. Such securities are carried at the lower of aggregate
cost or quoted market value.

Inventory

Inventories are stated at the lower of cost or market and include material,
labor and overhead.  Cost is determined using the first-in, first-out (FIFO)
method of inventory valuation.

Plant and Equipment

Plant and equipment are recorded at cost and depreciated for financial statement
purposes using the straight-line method over estimated useful lives of five to
seven years.  Gains or losses on dispositions are included in the statement of
operations in the period incurred.  Maintenance and repair cost are charged to
expense as incurred.

Intangible Assets

Intangible assets, consisting principally of patent costs, are amortized using
the straight-line method over an estimated useful life of 10 years.  Accumulated
amortization of intangible assets amounted to $119,000 and $144,000 at December
31, 1995 and 1996, respectively.

Impairment

Periodically, the Company evaluates the carrying value of its property, plant
and equipment, and long-lived assets by comparing the anticipated undiscounted
future net cash flows associated with those assets to the related net book
value.  As of December 31, 1996, no impairment was indicated.

Revenue Recognition

Revenues from POSICAM(TM) system contracts are recognized when all significant
costs have been incurred and the system has been shipped to the customer.
Billings on incomplete contracts are classified as unearned revenue on the
balance sheet.

Revenues from fee per scan contracts are recognized upon performance of  patient
scans.

Revenues from maintenance contracts are recognized over the term of the
contract.  Service revenues are recognized upon performance of the services.

Research and Development Expense

All costs related to research and development are charged to expense as
incurred.

Warranty Costs

The Company accrues for the costs of product warranty on POSICAM(TM) systems at
the time of shipment. Warranty periods generally range up to a maximum of one
year. Actual results could differ from the amounts estimated.

                                      F-8

Net Loss Per Common Share

Net loss per common share for the years ended December 31, 1995 and 1996 have
been computed by dividing net loss by the weighted average number of shares of
Common Stock outstanding during these periods.  All common stock equivalents
were antidilutive.

Estimates
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.

Fair Value of Financial Instruments

The Company includes fair value information in the notes to the financial
statements when the fair value of its financial   instruments is different from
the book value.  The book value of those financial instruments that are
classified as current   assets or liabilities approximates fair value because of
the short maturity of these instruments.

Reclassifications

Certain amounts have been have been reclassified in order to conform to current-
year presentations.

4.    REVOLVING LINE OF CREDIT
 
On February 7, 1996, the Company entered into a lending facility with Boston
Financial & Equity Corporation pursuant to which the Company may borrow up to
80% of its outstanding qualified accounts receivable (the "BF&E Loan"). The
maximum amount available under the BF&E Loan is $1,000,000 and the BF&E Loan is
collateralized by liens and security interests encumbering most of the Company's
assets including the Company's know-how, patents and proprietary rights
pertaining to its PET technology. As of December 31, 1996, the available
borrowing capacity under the BF&E Loan was approximately $100,000 and
approximately $75,000 was outstanding under the BF&E Loan. The fair value of the
line of credit approximates carrying value at December 31, 1996. The BF&E Loan,
as amended, bears interest at 13.8% per year and matured on March 31, 1997. On
March 31, 1997, BF&E agreed to an extension of the loan agreement until April
30, 1997. Other terms and conditions remain unchanged. In connection with the
BF&E Loan, the Company granted warrants to BF&E to purchase 45,000 shares of
Common Stock, at an exercise price of $2.00 per share (fair market value)
exercisable through February 7, 2001. The warrants contain standard anti-
dilution provisions and registration rights with respect to the shares of Common
Stock issuable upon the exercise thereof.

5.  NOTES PAYABLE

Notes Payable, Affiliate

During the last quarter of 1995 and the first quarter of 1996, in order to fund
its activities, the Company borrowed a total of $1,313,000 from Uro-Tech, Ltd.,
(the "Uro-Tech Loan"), an affiliate of the Company. The Uro-Tech Loan, as
amended, bears interest at 13.8% per annum, matures on March 31, 1997. On March
31, 1997, Uro-Tech agreed to an extension of the loan agreement until April 30,
1997. Other terms and conditions of the agreement remain unchanged. The Uro-Tech
Loan is collateralized by liens and security interests encumbering most of the
Company's assets including the Company's know-how, patents and proprietary
rights pertaining to its PET technology. The fair value of the line of credit
approximates carrying value at December 31, 1996. As part of the private
placement of Series A Preferred Stock, $650,000 of the outstanding principal
balance of the Uro-Tech Loan was converted into Series A Preferred Stock. As of
December 31, 1996, approximately $663,000 was payable to Uro-Tech, Ltd. In
connection with the loan from Uro-Tech, the Company granted Uro-Tech warrants to
purchase 67,500 shares of Common Stock, at an exercise price of $2.00 per share
exercisable through February 7, 2001.

Notes Payable, Other


On November 14, 1996, in order to fund its activities, the Company obtained a
loan facility of $1,400,000 from ProFutures Bridge Capital, L.P. (the
"ProFutures Loan"). The ProFutures Loan bears interest at a rate of 12% until
April 1, 1997, at which time, the rate increases to 15%. The loan matures June
30, 1997. For the debt outstanding after November 30, 1997, the interest rate
will increase to 18% per annum. The fair value of the line of credit
approximates carrying value at December 31, 1996. As of December 31, 1996,
approximately $1,335,000 was outstanding under the ProFutures Loan. The
ProFutures Loan is collateralized by liens and security interest encumbering all
of the assets of the Company, including know-how, patents and proprietary rights
pertaining to its PET technology. In addition, the Company granted ProFutures
Bridge Capital, L.P. a ten year warrant to purchase 250,000 shares of its common
stock at an exercise price of $2.40 per share. If the ProFutures Loan is not
repaid on or before April 1, 1997, the Company is required to grant to
ProFutures additional warrants for the purchase of an additional 100,000 shares
of its common stock. The exercise price of such additional warrants will be
determined based upon the average closing trading price for the Company's common
stock for the ten (10) trading days prior to April 1, 1997, but not less than
fair market value.

6.  COMMON STOCK -- OPTIONS AND WARRANTS:

Options

In 1987, the Company established a common stock option plan (the "1987 Plan")
covering directors, officers and other key employees. In November 1993, the
Company canceled all options outstanding under the 1987 Plan. In connection with
such cancellation, the board of directors authorized the reissuance of 38,522
options to purchase shares of common stock at 75 percent of the IPO price
following the closing of an initial public offering. Such options vested and
became exercisable on January 3, 1995. In addition in February 1994, the board
of directors authorized the issuance of an additional 150,000 options at the
same exercise price. Options granted under the 1987 Plan expire on the earlier
of three months after termination of employment or ten years from the grant
date.

Effective June 3, 1994, the shareholders of the Company approved the 1994
Incentive and Nonstatutory Option Plan" (the "1994 Plan").  The 1994 Plan as
amended in 1995 provides for the issuance of an aggregate of 601,833 Common
Stock options to key employees, directors, and certain consultants and advisors
of the Company.  The 1994 Plan provides that the exercise price of Incentive
Options shall not be less than the fair market value of the shares on the date
of the grant.  The exercise price per share of Nonstatutory options shall not be
less than the par value of the Common Stock or 50% of the fair market value of
the common stock on the date of grant.  The 1994 Plan is administered by the
Compensation Committee of the Board of Directors.  The committee has the
authority to determine the individuals to whom awards will be made, the

                                      F-11
<PAGE>
 
amount of the awards, and all other terms and conditions of the awards.  As of
December 31, 1996, options to purchase an aggregate of 144,389 shares of common
stock at a range of $2.626 - $4.125 per share, had been granted to certain key
employees.

The 1994 Plan also provides that each non-employee director automatically
receives options to purchase 10,500 shares of common stock as of the date such
individual becomes a non-employee director and each non-employee director who is
a director on the first business day following each Annual Shareholder Meeting
also receives an option to purchase a number of shares of common stock having a
value of $15,000 as determined by the fair market value of the common stock on
the date of grant.  As of December 31, 1996, options to purchase an aggregate of
163,724 shares of common stock at a range of $2.625-$4.125 per share had been
granted to non-employee directors.  All 1994 options expire within ten years of

The Financial Accounting Standards Board ("FASB") issued Statement of Financial
Accounting Standards No. 123, Accounting for Stock-Based Compensation ("SFAS
123") in 1995 which, if fully adopted by the Company would change the methods
the Company applies in recognizing the cost of the Plan.  Adoption of the cost
recognition provisions of SFAS 123 is optional and the Company has decided not
to elect those provisions.  As a result, the Company continues to apply
Accounting Principles Board Opinion No. 25 ("APB 25") and related the
Interpretations of APB 25 in accounting for the measurement and recognition of
the Plan's cost.

The weighted average fair value of options granted was $0 and $2.08 during the
years ended December 31, 1996 and 1995, respectively. The weighted average fair
value charge for options repriced was $0 and $0.54 during the years ended
December 31, 1996 and 1995, respectively.

Under SFAS 123, compensation cost is measured at the grant date based on the
fair value of the awards and is recognized over the service period, which is
usually the vesting period. The fair value of options granted during 1996 and
1995 is estimated on the date of grant using the Black Scholes option-pricing
model with the following assumptions used to calculate fair values of options
awarded in both 1996 and 1995: (i) average dividend yield of 0.00%, (ii)
expected volatility of 83.36%, (iii) expected life of five (5) years, and (iv)
an estimated risk-free interest rate, which is different for grants awarded on
different grant dates, ranging from 5.66% to 7.15%.

requirements of SFAS 123 are as follows (in thousands):

awards in future years are anticipated by the Company.

Warrants

Prior to the Company's initial public offering, the Company issued warrants to
the purchasers of the then outstanding Series E Preferred Stock (the "1993
Warrants"). Subject to adjustment for certain transactions, the 1993 Warrants as
originally issued, were exercisable for an aggregate of 353,531 shares of Common
Stock at an exercise price of $9.90. Because of certain specified anti-dilution
provisions, the 1993 Warrants were exercisable for an aggregate of 519,394
shares of Common Stock at a purchase price of $5.60 per share as of December 31,
1996. The 1993 Warrants are exercisable at any time until November 30, 1998 and
are entitled to the benefit of adjustments in the exercise price and in the
number of shares

                                      F-13
<PAGE>
 
of Common Stock or other securities deliverable upon the exercise thereof in the
event of a stock dividend, stock split, reclassification, reorganization,
consolidation, merger, sale of all or substantially all of the property of the
Company, or other dilutive transactions.

The 1993 Warrants are redeemable at the option of the Company at a price equal
to $.10 per share of the Common Stock covered by the 1993 Warrant, on 30 days
written notice, provided that the market price of the Common Stock equals or
exceeds $12.544 for the 20 consecutive trading days ending within 10 days prior
to the notice of redemption. The Company also granted the holders of the 1993
Warrants certain registration rights with respect to the 1993 Warrants and the
Common Stock for which the 1993 Warrants are exercisable.
    
In connection with its initial public offering, the Company issued 3,893,550
Redeemable Warrants (the "Redeemable Warrants"). The Redeemable Warrants as
originally issued were exercisable for an aggregate of 3,893,550 shares of
Common Stock at an exercise price of $8.25 per share. Because of their anti-
dilution provisions the Redeemable Warrants were exercisable for an aggregate of
5,646,798 shares of Common Stock at a purchase price of $5.60 per share as of
December 31, 1996. The Redeemable Warrants are entitled to the benefit of
adjustments in the exercise price and in the number of shares of Common Stock or
other securities deliverable upon the exercise thereof in the event of a stock
dividend, stock split, reclassification, reorganization, consolidation, merger,
sale of all or substantially all of the property of the Company, or other
dilutive transactions. The Company has the right to reduce the exercise price or
increase the number of shares of Common Stock issuable upon the exercise of the
Redeemable Warrants.     

Each Redeemable Warrant expires on December 3, 1998 (the "Expiration Date"),
subject to extension. The Company may at any time extend the Expiration Date of
all outstanding Redeemable Warrants for such increased period of time as it may
determine.

The Company has the right at any time after March 3, 1995, to redeem the
Redeemable Warrants in whole or in part for cancellation at a price of $1.25
each, by written notice to each Redeemable Warrant holder. Such notice may only
be given within 10 days following any period of 20 consecutive trading days
during which the average closing bid for the Common Stock (if then trading on
the over-the-counter market) or the average closing price of the Common Stock
(if then listed on the Nasdaq Market) equals or exceed $12.544 per share,
subject to adjustment for stock dividends, splits and similar events. If the
Redeemable Warrants are called for cancellation, they must be exercised prior to
the close of business on the date of any such redemption and cancellation or the
right to purchase the applicable shares of Common Stock is forfeited. The
Company granted the holders of the Redeemable Warrants certain registration
rights with respect to the Common Stock for which the Redeemable Warrants are
exercisable.

No compensation expense was recognized by the Company in the accompanying
statement of operations under the provision   of APB 25 during the years ending
December 31, 1996 and 1995, respectively.

The Company has reserved 10,687,000 shares of common stock for issuance upon the
exercise of all employee and non-  employee director common stock options and
outstanding warrants.

7.  PREFERRED STOCK:

The Company's Articles of Incorporation authorize the board of directors to
issue 10,000,000 shares of preferred stock from time to time in one or more
series. The board of directors is authorized to determine, prior to issuing any
such series of preferred stock and without any vote or action by the
shareholders, the rights, preferences, privileges and restrictions of the shares
of such series, including dividend rights, voting rights, terms of redemption,
the provisions of any purchase, retirement or sinking fund to be provided for
the shares of any series, conversion and exchange rights, the preferences upon
any distribution of the assets of the Company, including in the event of
voluntary or involuntary liquidation, dissolution or winding up of the Company,
and the preferences and relative rights among each series of preferred stock.

Series A Preferred Stock

In February, March and May of 1996, the Company issued 3,075,318 shares of
Series A 8% Cumulative Convertible Redeemable Preferred Stock $1.00 par value
("Series A Preferred Stock") and Redeemable Common Stock Purchase Warrants to
purchase 1,537,696 shares of the Company's Common Stock. The net proceeds of the
private placement were approximately $2,972,000. Each share of the Series A
Preferred Stock is immediately convertible into one share of Common Stock. Each
Redeemable Common Stock Purchase Warrant is exercisable at a price of $2.00 per
share of Common Stock. Eight percent (8%) dividends on the Series A Preferred
Stock may be paid in cash or the Series A Preferred Stock at the discretion of
the Company The Series A Preferred Stock is senior to the Company's Series B
Preferred Stock and Common Stock in liquidation. Holders of the Series A
Preferred Stock may vote on an as if converted basis on any matter requiring
shareholder vote. While the Series A Preferred Stock is outstanding or any
dividends thereon remain 

                                      F-15
<PAGE>
 
unpaid, no Common Stock dividends may be paid or declared by the Company.

In conjunction with the issuance of the aforementioned Series A Preferred Stock,
Uro-Tech, converted $650,000 of the amount payable to it into 433,329 shares of
Series A Preferred Stock and 216,671 Redeemable Stock Purchase Warrants.

Series B Preferred Stock

In July 1996, the Company issued 25,000 shares of Series B 8% Cumulative
Convertible Redeemable Preferred Stock $1.00 par value ("Series B Preferred
Stock") and Common Stock Purchase Warrants to purchase up to 100,000 shares of
its Common Stock, par value $.01 per share. The Series B Preferred Stock plus
Common Stock Purchase Warrants sold for approximately $50.00 per share of Series
B Preferred Stock. Subject to adjustment for certain antidilution events, each
share of Series B Preferred Stock is initially convertible into 25 shares of
Common Stock and each Common Stock Purchase Warrant is exercisable for one share
of Common Stock at an exercise price of $2.00 per share. Eight percent (8%)
dividends on the Company's Series B preferred Stock may be paid in cash or the
Series B Preferred Stock. The Series B Preferred Stock is junior to the Series A
Preferred Stock, but senior to the Company's Common Stock in liquidation. The
Series B Preferred Stock has no voting rights other than those afforded by law
as a class, however, the holder's of the Series B Preferred Stock may vote on
matters directly affecting the Series B Preferred Stock or mergers and/or
consolidations of the Company with another company. Dividends may not be paid or
declared on the Company's Common Stock while any unpaid dividends are
outstanding on the Series B Preferred Stock. The Series B Preferred Stock and
the Common Stock Purchase Warrants are not convertible or exercisable until such
time as the Company's shareholders approve an amendment to its Articles of
Incorporation increasing the number of the authorized shares of Common Stock by
at least 2,500,000 shares.

As of December 31, 1996, stated dividends of $184,078 and $948 are undeclared
and unpaid on the Series A and Series B Preferred Stocks, respectively. The
Company anticipates that such dividends, when declared, will be paid in the
shares of Series A and Series B Preferred Stock.

8.  INCOME TAXES:

The Company has incurred losses since its inception and, therefore, has not been
subject to federal income taxes. As of December 31, 1996, the Company had net
operating loss ("NOL") carry forwards for income tax purposes of approximately
$38,300,000 which expire in 1999 through 2011. Since the closing of the
Company's IPO resulted in more than a 50 percent change in shareholder ownership
percentages, the provisions of Section 382 of the Internal Revenue Code limit
the Company's ability to utilize these NOL carry forwards to reduce future
taxable income and tax liabilities. Additionally, because United States tax laws
limit the time during which NOL carry forwards may be applied against future
taxable income, the Company will not be able to take full advantage of its NOL
for federal income tax purposes should the Company generate taxable income.

Deferred tax assets of $13,200,000 and $14,900,000, resulting from loss carry
forwards as of December 31, 1995 and 1996, respectively, have been fully
reserved. The change in the valuation allowance for the year ended December 31,
1996 was a net increase of $1,700,000 resulting primarily from operating losses
incurred in 1996.

The Company has significant NOL carry forwards for which realization of tax
benefits is uncertain and has no deferred income taxes as of December 31, 1995
and 1996.

                                      F-16

9. 401(k) PLAN:
 
The Positron Corporation 401(k) Plan and Trust (the "Plan"), covers all of the
Company's employees who are United States citizens, at least 21 years of age and
have completed at least one quarter of service with the Company. Pursuant to the
Plan, employees may elect to reduce their current compensation by up to the
statutorily prescribed annual limit and have the amount of such reduction
contributed to the Plan. The Plan provides for the Company to make contributions
in an amount equal to 25 percent of the participant's deferral contributions, up
to 6 percent of the employee's compensation, as defined in the Plan agreement.
The Company's contribution expense was approximately $35,000 and $38,000 in 1995
and 1996, respectively. Additionally, the board of directors of the Company may
authorize additional contributions. No Company contributions have been made as
of December 31, 1996.

 
10. RELATED-PARTY TRANSACTIONS:
 
The Company has an incentive compensation plan for certain key employees and its
Chairman. The incentive compensation plan provides for annual bonus payments
based upon achievement of certain corporate objectives as determined by the
Company's compensation committee, subject to the approval of the board of
directors. To date, the Company has not paid any bonuses pursuant to the
incentive compensation plan.
 
Pursuant to agreements entered into in November 1993, the Company extended loans
to a current board member and a former board member in order to provide each of
them with funds to satisfy their respective personal income tax liability
arising out of the conversion of certain Positron Corporation Promissory Notes
into Common Stock. Such agreements were entered into by the Company in
connection with the IPO and in consideration of certain concessions made by the
board member and former board member concerning the conversion terms under their
respective Notes. Pursuant to the agreements, each of the loans were made on
substantially the following terms: (i) limited to a principal amount not to
exceed $175,000, (ii) interest payable at a rate of six percent per year, (iii)
an initial term of three years with the principal balance being due and payable
upon the expiration of the term, (iv) limited recourse against the borrower, and
(v) collateralized by Positron Corporation Common Stock owned by the borrower.
In accordance with such agreements, on April 15, 1994, the Company extended a
$165,817 loan to the current board member and a $158,552 loan to the former
board member.

The Company has certain consulting agreements with its Chairman and a member of
its board. The agreements provide for monthly consulting payments of $6,667 to
each of them. The agreement with its Chairman expires in December 1998 and the
agreement with the member of its board expires in 1998.

11.  COMMITMENTS AND CONTINGENCIES:

On January 1, 1996, the Company entered into an employment agreement with Werner
J. Haas, Ph.D. pursuant to which Dr. Haas agreed to serve as President and Chief
Executive Officer of the Company for a term of two years. The employment
agreement provided for the payment of an annual base salary of $200,000, bonuses
in an amount to be determined at the discretion of the Board of Directors of the
Company, and participation in any employee benefit plan adopted by the Company
for its employees.

On February 18, 1997, Dr. Haas informed the Board of Directors of the Company
that he considered his contract to have been terminated by the Company without
cause as a result of the Company's failure to pay the February 15, 1997 payroll
to any of its management level employees and specifically to him. Additionally,
Dr. Haas resigned as a member of the Company's Board of Directors. Dr. Haas has
demanded that the Company pay to him all past due salary as well as the nine
months severance pay specified in his employment agreement if his contract is
determined to have been terminated without cause. The Company has indicated to
Dr. Haas that it believes no amounts are due him under his employment agreement.
As of March 15, 1997, the Company is unable to predict the outcome of the
disagreement between Dr. Haas and the Company.

Gary B. Wood, Ph.D., currently the Company's Chairman, has assumed the
additional duties of president and Chief

12.  GENERAL ELECTRIC TRANSACTION

In July 1996, the Company and GE entered into an Acquisition Agreement (the
"Agreement"), which initially expired on January 4, 1997, pursuant to which the
Company agreed to purchase a portion of GE's product line relating to the
design, engineering and manufacture of certain PET equipment and related
cyclotron systems (the "Business"). Under the terms of the Agreement, the
Company agreed to (i) purchase from GE all of the capital stock of its wholly-
owned Swedish subsidiary, and (ii) purchase or license from GE substantially all
of its assets which are used principally in the conduct of the Business.
Additionally ,the Company and GE entered into a Sales and Marketing Agreement
(the "Marketing Agreement") pursuant to which, subject to the conditions and
limitations set forth therein, GE agreed to purchase on an exclusive basis, and
the Company agreed to supply to GE, certain PET equipment and related cyclotron
systems (collectively the "PET Products"). The initial term of the Marketing
Agreement was for five (5) years. Subject to the conditions set forth therein,
GE agreed that, during the initial term of the Marketing Agreement, GE would
not, directly or indirectly engage in the design, engineering of manufacture of
PET Products.

In exchange for the sale by GE of the assets described above and the capital
stock of its Swedish subsidiary, as well as the performance by GE of its
obligations under the Marketing Agreement, the Company agreed to pay to GE cash
of $25 million, subject to certain specified adjustments. Additionally, the
Company agreed to issue to GE a number of shares of its Common Stock (the
"Acquisition Stock") which, would equal 10% of the Common Stock outstanding
immediately after consummation of the acquisition and the issuance of the
Acquisition Stock, assuming conversion of all outstanding shares of the
Company's convertible preferred stock and related common stock purchase warrants
and the issuance and exercise of the GE Option (described below). The Company
also agreed to issue to GE an option (the "GE Option") to purchase a number of
shares of Common Stock which, upon exercise and conversion into shares of the
Company's Common Stock, would equal 15% of the Common Stock outstanding
immediately after consummation of the acquisition and the issuance of the
Acquisition Stock, assuming conversion of all outstanding shares of the
Company's convertible preferred stock and the issuance, exercise and conversion
of the GE Option. The GE Option was initially exercisable for three (3) years at
an exercise price of $4.25 per share. On January 4, 1997, GE and the Company
agreed to extend the expiration date of the Agreement until March 31, 1997.

The acquisition is subject to the satisfaction or waiver of certain conditions
precedent, including the Company's procurement of financing upon terms and
conditions acceptable to the Company and the approval by the Company's
shareholders of certain terms of the acquisition, including the issuance of the
Acquisition Stock and GE Option. Under certain circumstances, if the Agreement
is terminated and the termination is not due to a breach by GE of its
representations, warranties or covenants set forth in the Agreement the Company
is required to pay to GE a termination fee of $1.5 million if the Company enters
into certain specified transactions within two (2) years of the date of
termination of the Agreement.

As of March 31, 1997, the Company has not obtained commitments for the financing
required to complete the acquisition, nor has it obtained shareholder approval
of the issuance of the Acquisition Stock, the GE Option or the Agreement. There
is no assurance that the Company will be able to procure the required financing
or that it will be successful in obtaining shareholder approval of the
transaction. Failure of the Company to close the acquisition of the Business or
obtain an alternate source of capital is likely to have a material and adverse
effect on the Company's ability to continue as a going concern.

Closing of the GE Acquisition did not occur on March 31, 1997, nor has GE agreed
to extend the Agreement beyond March 31, 1997. On April 10, 1997, GE informed
the Company that it was exercising its right to terminate the Agreement and that
it will pursue other options for its PET business. GE remains open to discussing
a transaction on revised terms, if and only if, (i) a prompt closing and payment
of the full purchase price are assured, (ii) the transaction continues to make
business sense for both parties, and (iii) all necessary details can be agreed
upon by the parties. The Company and GE have no binding agreement to proceed
with these discussions, nor can any assurances be given that if they do proceed,
any workable agreement will be reached by the parties.

13.  RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In March 1997, the Financial Accounting Standards Board ("FASB") issued SFAS No.
128, Earnings Per Share, which establishes specific computation, presentation
and disclosure requirements for earnings per share for entities with publicly
held common stock or potential common stock in order to simplify the computation
of earnings per share and make it compatible with the standards of other
countries and with that of the International Standards committee.  SFAS 128 is
effective for financial statements of both interim and annual periods ending
after December 15, 1997.

In March 1996, the FASB issued SFAS No. 129, Disclosure of Information About
Capital Structure, which applies to all entities and is effective for financial
statements of periods ending after December 15, 1997.

The Company is currently evaluating its alternatives under both SFAS No. 128 and
No. 129; however, their impact on operating results when initially adopted is
expected to be immaterial.
