PART I
ITEM 1.   BUSINESS
- -------   --------

General
- -------

ADAC Laboratories ("ADAC" or "the Company") designs, develops, manufactures,
sells and services medical imaging and information systems used in hospitals and
clinics worldwide.  The Company's products include applications for nuclear
medicine, laboratory, radiology, cardiology and oncology.  In July 1995, ADAC
completed the acquisition of Community Health Computing (CHC), a provider of
radiology and laboratory healthcare information systems.  This acquisition is
expected to expand the Company's addressable information systems business in
markets not previously serviced by the Company.

The Company markets the following diagnostic imaging systems and information
systems:

          Medical Systems
               - Nuclear Medicine Systems
               - Radiation Therapy Planning Systems
               - Digital Angiography Systems
          HealthCare Information Systems
               - Radiology Information Systems
               - Laboratory Information Systems

ADAC was incorporated in California on October 14, 1970.  Its principal offices
are located at 540 Alder Drive, Milpitas, California, 95035.  Its telephone
number at that location is (408) 321-9100.

PRODUCTS

Nuclear Medicine Systems
- ------------------------

Nuclear medicine is a diagnostic imaging procedure where the patient is
administered a radiotracer compound.  This compound is either injected or
swallowed and flows to the organ(s) under examination.  The patient is then
scanned with a gamma camera which detects the radiotracer emissions from these
organ(s).  The data from the emissions are then processed to provide the
physician with images and information regarding the functional and metabolic
performance of the organ(s).  The physician uses this information for the
diagnosis of diseases and the evaluation of disease progression (staging),
including cardiology, oncology and neurology.

ADAC's gamma cameras are primarily designed to perform superior Single Photon
Emission Computed Tomography (SPECT) imaging.  In addition to SPECT, ADAC has
recently developed the technology for its dual head gamma cameras to perform
coincidence imaging using Molecular Coincidence Detection (MCD(TM)).

Although market acceptance of dual head gamma cameras accelerated the
replacement cycle of imaging systems, the ongoing restructuring of the
healthcare delivery system in the United States caused many hospitals to reduce
their capital budgets.  ADAC estimates that the net effect of these two
conditions resulted in unchanged North American, European and Japanese market
volumes compared to 1994.  However, the Asian and Latin American marketplaces
are expanding primarily due to new capacity additions.

The nuclear medicine market is characterized by two distinct segments: single
head cameras and multihead cameras. ADAC is a market leader in both segments
with the ARGUS EPIC(TM), CIRRUS EPIC(TM), and GENESYS(TM) single head products
which have one detector head and DUAL GENESYS(TM), VERTEX EPIC(TM), SOLUS
EPIC(TM) and CARDIO EPIC(TM) dual head products which have two detector heads.
These systems are interfaced with ADAC's PEGASYS(TM), the leading UNIX-based
nuclear medicine workstation. The TRANSCAM(TM), THYRUS, and POLARIS are niche
gamma cameras produced by the Company's Danish subsidiary, ADAC A/S. These
cameras which began shipping in early fiscal 1993 offer specialized
functionality for specific clinical procedures.

                                       3
<PAGE>
 
ADAC generated approximately 80% of its nuclear medicine revenue in fiscal 1995
in the dual head market.  Dual head cameras are complex systems that provide
enhanced diagnostic accuracy and increased patient throughput efficiency
primarily for oncology and cardiology procedures.  These comprise approximately
70% of all nuclear medicine procedures performed.  Single head cameras are less
complex and expensive.  Therefore, the most likely purchasers are capital-
constrained institutions and those adding extra capacity.

The VERTEX camera introduced in late 1992 is the cornerstone of ADAC's product
line.  It has the unique capability of variably positioning its two detectors in
either a 180 degree orientation for whole body imaging or a 90 degree
orientation for cardiac imaging.  This capability enables nuclear medicine
departments to increase their patient throughput by decreasing the time required
to perform the procedures.  In 1995, the VERTEX contributed over 60% of the
Company's nuclear medicine product revenues and has allowed ADAC to accelerate
its penetration into markets throughout the world.

In 1994, ADAC introduced the EPIC(TM) digital detector.  This innovative new
technology obsoleted analog technology and created a new generation of high
performance cameras:  VERTEX EPIC, GENESYS EPIC, CIRRUS EPIC and ARGUS EPIC.
The EPIC digital detector significantly improves the reliability and stability
of nuclear image quality versus the analog detector.  Also, the EPIC's auto-
tuning and remote diagnostics capabilities have improved both ADAC's field
service efficiency as well as customer satisfaction.  EPIC began shipping in
November 1994.

In June 1995, the dual head gamma camera segment was further extended with the
introduction of two new imaging systems:  the SOLUS EPIC, a fixed 180 degree
camera for oncology, and the CARDIO EPIC, a fixed 90 degree camera for
cardiology.  These systems satisfy the needs of special niche markets by
providing less expensive products with VERTEX EPIC imaging quality and
throughput advantages.

In June 1995, ADAC introduced a new technology called Molecular Coincidence
Detection (MCD(TM)).  This technology enables ADAC's VERTEX EPIC and SOLUS EPIC
cameras to perform coincidence imaging previously only available on expensive
dedicated Positron Emission Tomography (PET) imaging systems costing between $1
million and $2 million.  Coincidence imaging is a valuable diagnostic tool
because of its high resolution and high accuracy in oncology, cardiology and
neurology.  It is particularly useful for identifying cancerous lesions
throughout the body.  Due to the high capital cost of PET systems, coincidence
imaging has been too expensive for all but a few hospitals and clinics.  MCD is
expected to provide the capability to perform coincidence imaging using ADAC's
cameras at a fraction of the cost of a dedicated PET system.  The Company
received Food and Drug Administration (FDA) 510k clearance for MCD in November
1995.  The Company will begin MCD multicenter clinical trials in early 1996.
These trials are expected to document the clinical efficacy of MCD while
verifying the significant reduction in the costs of managing cancer patients
relative to conventional diagnostic techniques.

VANTAGE(TM), introduced in December 1994, is an optional upgrade to the VERTEX
EPIC and the CARDIO EPIC. This option performs non-uniform attenuation
correction which improves the diagnostic accuracy of nuclear medicine imaging by
correcting for attenuation artifacts (random dark areas which compromise
diagnostic accuracy). The ability to determine true defects is particularly
important in nuclear cardiology and is believed to be an important advantage
versus cardiac ultrasound, the primary competitive procedure. VANTAGE is
currently in the final phase of a multicenter clinical trial that is expected to
demonstrate improved cost-effectiveness and quality compared to current cardiac
imaging techniques. The Company received FDA 510k clearance for VANTAGE in April
1995.

MACROVISION(TM), introduced at the 1994 Radiological Society of North America
trade show, is a new object-oriented programming tool that the Company has
exclusively licensed from Advanced Visual Systems Inc. for use in nuclear
medicine. MACROVISION is designed to improve the Company's software development
productivity and also to

                                       4
<PAGE>
 
improve the customers' programming flexibility in developing unique clinical
protocols.

In November 1995, ADAC acquired JD Technical Services, Inc.  Through this
acquisition, ADAC believes it has gained the expertise to enter the multivendor
refurbished nuclear medicine instrumentation market.

Sales of Nuclear Medicine imaging systems, optics and accessories accounted for
nearly 67%, 67% and 66% of total Company revenues in fiscal years 1995, 1994 and
1993, respectively.

Radiation Therapy Planning Systems
- ----------------------------------

Radiation Therapy Planning systems are "turnkey" computer systems that assist
hospital radiation therapy departments and cancer treatment centers in planning
patient treatments.

The Company has developed software for a new treatment planning computer
product, called Pinnacle/3/(TM) which combines two dimensional and three
dimensional planning, including stereotactic radiosurgery planning capabilities.
Stereotactic radiosurgery is the precise application of radiation beams to a
specific targeted area.  The Company believes Pinnacle/3/ will significantly
improve image processing and dose calculation methods compared to currently
available products.  The FDA cleared the stereotactic radiosurgery component of
the product in November 1994.  The external beam and body therapy capabilities
produce a three dimensional volumetric patient model and directs the application
of radiation therapy beams to the treatment volume. These capabilities are still
pending FDA 510k clearance.  Pinnacle/3/'s external beam and body therapy
capabilities have recently been introduced into the international markets with
very positive results.  The Company believes that the treatment planning systems
may see significant revenue and income improvement due to this international
penetration.  Historically, Radiation Therapy Planning Systems have not been a
significant contributor to Company revenues or income.

Digital Angiography Systems
- ---------------------------

ADAC services existing ADAC X-Ray imaging and digital angiography computer
systems for both radiology and cardiology applications.  Sales of digital
angiography products have not been a significant contributor to the company
revenues or income over the past three years.

HealthCare Information Systems
- ------------------------------

Information systems for the healthcare industry consist of computer equipment
and software applications designed to offer healthcare providers the mechanism
to process and archive patient and clinical information.  The healthcare
environment is changing to one where managed care and health maintenance
organizations demand information technology to capture and manage costs as well
as measure the quality and results of patient care.

A key objective of ADAC is to expand the Company's healthcare information
systems business.  In November 1993, ADAC acquired SD&G Healthcare Systems Inc.
(SD&G) which strengthened the Company's market share and revenues in the
radiology information systems business.  In July 1995, ADAC acquired Community
Health Computing, Inc. (CHC) for approximately $18.4 million which included $1.9
million of expenses associated with the acquisition.  The acquisition of CHC
strengthened ADAC's market share and revenue in the radiology information
systems business and established its presence in the laboratory information
systems business.  ADAC's information systems products and services have been
combined to form a subsidiary business unit named ADAC HealthCare Information
Systems.

The Company's existing products (MARS II(TM), IMAGES/3000(TM), RadCare(TM), 
MRM(TM), RadStat(R), and LabCare(TM)) are installed in over 300 hospitals
throughout the United States and Canada. These hospitals represent a cross-
section of major teaching hospitals,

                                       5
<PAGE>
 
large and small community hospitals, children's hospitals, and city and state
institutions.

During 1995, ADAC HealthCare Information Systems began installation of its two
major product developments. QuadRIS(TM), a radiology information systems
product, and LabStat(TM), a laboratory information systems product, represent
significant investments in advanced client server architectures. ADAC developed
both products with the latest open systems technology, including SQL relational
database servers and Microsoft Windows based applications. QuadRIS is available
on Hewlett Packard and IBM UNIX servers. LabStat is currently available on
Hewlett Packard UNIX servers.

Both QuadRIS and LabStat are designed to work in a distributed computing
environment to meet the needs of rapidly changing integrated healthcare delivery
systems.  In this environment, the products must meet the demands of multiple
healthcare facilities that act as a single integrated delivery network.

In 1995, CHC diluted ADAC's earnings by approximately three cents per share
primarily because the laboratory product line was unprofitable during
development and product introduction.  ADAC HealthCare Information Systems
revenue in 1995 was approximately 7% of total Company revenues.

Field Service
- -------------

The Company maintains its own service force in North America and Europe,
supporting over 5,900 installed systems at over 2,100 sites.  This network of
service engineers and applications specialists provides installation, warranty,
repair, and training services.

The Company's products are sold with warranty periods of generally one year.  At
the end of the warranty period, the Company provides customers with the option
of purchasing a service contract or obtaining continuing service on a "per call"
basis. The Company's warranty program is similar to those offered by most
manufacturers of medical electronic equipment.

In November 1995, ADAC acquired JD Technical Services, Inc. which expanded the
Company's capabilities to service and support gamma cameras of the major
vendors.

Service revenues represented 26%, 23% and 23% of total Company revenues in
fiscal years 1995, 1994 and 1993, respectively.

Marketing
- ---------

ADAC has a direct sales force in North America which generates approximately 77%
of all product, service and system sales.  The Company maintains sales and
service subsidiaries in the Netherlands, Germany, France, Italy, Denmark, the
United Kingdom, Singapore, and Canada to market and service its products.  Sales
and service in other countries are generally handled by distributors.

North America is the largest market for the Company's products, systems and
services followed by Europe, Japan, Asia Pacific and Latin America.  ADAC is
represented in all these geographic areas.  Until 1995, ADAC had not been
represented in Japan, the third largest market in the world.  In December 1994,
ADAC signed a distribution agreement with Sumitomo Metal Industries.  In June
1995, ADAC received approval from the Japanese Ministry of Health and Welfare to
market the VERTEX EPIC throughout Japan.

Research and Development
- ------------------------

Developing products, systems and services based on advanced technological
concepts is essential to ADAC's ability to compete effectively.  The Company
currently maintains a full-time product development and engineering staff
responsible for product design and engineering.

                                       6
<PAGE>
 
As part of ADAC's research and development programs, the Company has established
the Advanced Clinical Research Program (ACRP) which provides annual grants to
clinical trial sites at major institutions to assist the Company in product
development concepts and to measure and establish product efficacy.

Research and development expenses, net of software capitalization, totaled
$10,081,000, $11,644,000, and $11,031,000 in fiscal years 1995, 1994, 1993,
respectively.

Competition
- -----------

In the Nuclear Medicine market, the Company competes with eight other suppliers
in providing integrated camera/computer imaging systems, optics and accessories.
According to the 1995 data provided by NEMA (National Electronics Manufacturers
Association), the industry trade group, ADAC's share of the U.S. market in 1995
is believed to be 45%, giving ADAC a substantial lead over its nearest
competitors.  In 1995, ADAC's worldwide market share is believed to be over 30%.

The Company believes that the key to success in its markets is to deliver cost-
effective and technologically superior products which meet or exceed customer
quality and service expectations.  ADAC's ability to compete successfully
depends on its capacity to commercialize new hardware technology and software
ahead of its competitors.  In addition to the rapid development of innovative
and cost-effective new products, the Company believes that other competitive
factors include patient throughput, system functionality and reliability, image
quality, computer processing speed, customer service and support and worldwide
distribution network.  The Company's products must focus on solutions for the
managed care environment in order to provide improved clinical outcomes at lower
clinical process costs.

With the acquisition of Community Health Computing (CHC), ADAC believes that it
is now the leader in the radiology information systems market with an estimated
11% market share.  The Company also entered the laboratory information systems
market through CHC but has not yet registered significant new product sales from
that business.  The company believes that key competitive factors include system
architecture, functionality of the application software, post-sales support
services, integration expertise with hospital information systems and price.

Manufacturing
- -------------

The Company manufactures most of the sub-systems used in its products and
systems.  Manufacturing includes printed circuit board assembly and test,
mechanical assembly, final system integration and testing.  In addition, the
Company purchases certain sub-systems, Sun Workstations and disk drives.

Although most materials and purchased components for Medical Systems products
are available from more than one source of supply, certain essential components
such as the Sun Workstations and sodium iodide crystals are presently available
from only one outside source.  There are also several significant vendors for
hardware and software components of the HealthCare Information Systems products:
LabStat vendors are Hewlett Packard and Oracle; QuadRIS vendors are Sybase and
Oracle; and LabCare's vendor is Stratus.   The loss of any single-source
supplier to ADAC would require obtaining one or more replacement suppliers as
well as potentially requiring a significant level of hardware and software
development to incorporate the new parts into the Company's products.  The
Company has obtained insurance to protect against loss due to business
interruption from these and other sources.

Government Regulation
- ---------------------

ADAC's Nuclear Medicine and Radiation Therapy Planning businesses are regulated
by the Food and Drug Administration ("FDA") under the Food, Drug, and Cosmetic
Act of 1976 and the Safe Medical Device Act of 1990.  Regulations include
meeting certain requirements related to marketing, manufacturing, labeling,
packaging and distribution of most of the Company's products.  The FDA has the
authority to issue new performance standards on any medical device.  Unscheduled
FDA inspections of the

                                       7
<PAGE>
 
Company's facilities may occur from time to time to determine compliance with
these and other FDA regulations.

Since certain requirements must be met prior to the initial marketing of medical
devices, the Company is required to make certain submissions to the FDA and
comply with Good Manufacturing Practices (GMP) which includes the creation and
maintenance of certain records.  The FDA requires all manufacturers of medical
devices to prove that their products are equivalent to predicate devices and are
safe and effective.  This process is known as 510k (pre-market notification).
The 510k clearance is required for all new medical devices before orders can be
obtained and the product distributed.  Currently, this clearance for new product
distribution is extending beyond the prescribed 90 day limit due to resource
issues within the FDA.  The Company is working with NEMA (National Electronics
Manufacturers Association) to reduce the time needed for FDA pre-market review.

In fiscal 1995, the Company submitted to the FDA three pre-market notifications
(pending 510k).  The Company also listed two new products via 510k,  Pinnacle/3/
and VANTAGE.  To date in fiscal 1996, the Company has listed MCD and
INSPECT/PROSPECT via 510k.  Occasionally, the Company receives Certificates for
Export from the FDA which are required in order to ship equipment to certain
foreign countries.

To ensure product safety and to maintain certification, ADAC's policy is to list
all its equipment with a national recognized testing laboratory such as ETL.  In
1995, ADAC had several revisions to its existing product listings.

In 1995, ADAC implemented a program to enter the Japanese market and has
received Japanese Ministry of Health and Welfare (JMHW) approval to market the
VERTEX EPIC.  The Company is planning to list additional products in the
Japanese market in 1996.  The process to receive approval to market these
additional products is expected to take four to six months each.  In addition,
ADAC is undertaking to meet the requirements of the European Medical Device
Directive which will become effective in most European countries by June 1998.

Certain additional requirements of other Federal laws and of state, local and
foreign governments exist which may apply to the manufacture and marketing of
the Company's products and to products such as radiopharmaceuticals which are
used in conjunction with the Company's products.  To date, the Company has not
experienced any significant difficulty in complying with the requirements
imposed on it by the FDA or other government agencies.

With the company's overall emphasis on total quality management, quality system
compliance is expected to continue to improve in 1996.  The Company is
anticipating that some costs will be incurred for compliance with the European
Medical Device Directive and the Japanese Medical Device listing.  These costs
are expected to be absorbed by revenues derived from the Company's expansion
into these markets.

Patent, Copyrights, and Royalties
- ---------------------------------

The Company has a policy of undertaking an ongoing review of its products with
patent counsel to determine to what extent its products may be protectable under
the patent or copyright laws.  ADAC also has a program in place to develop
patent portfolios to protect its intellectual property.  The Company holds
Patent Des. 323,386, a system design patent for the GENESYS gamma camera.  In
1994, in addition to receiving approval of three patents, the Company purchased
thirteen patents related to the field of nuclear medicine from Philips
Electronics N.V.  In 1995, the Company received approval of nineteen United
States patents and forty-two foreign patents.  The Company has a total of
thirty-one patents pending at various stages of completion.  Several patent
applications have been submitted for MCD.  While the Company believes that it
benefits from such patents, competitors may develop competing products by
"designing around" patents held by the Company.

The Company develops user software for its products and also uses software from
outside sources as part of a deliverable software package.  ADAC owns all
licenses for software developed by the Company's internal software engineering
department. Outside sources include software companies and clinical development
sites that

                                       8
<PAGE>
 
provide turnkey products or software code. The Company believes the risk of
losing access to software applications provided by outside vendors is
negligible. The Company has negotiated contracts with these vendors which often
include clauses that stipulate: 1) specific deliverables within specific time
periods, 2) distribution and renewal agreements, and 3) procedures where related
software code would be placed in escrow in the event adverse business conditions
impact the vendor's ability to deliver the software contracted. In some cases,
royalties are paid to the software originator.

Employees
- ---------

The Company had 559 full-time employees worldwide prior to the July 1995 
acquisition of Community Health Computing which added 122 employees.

ITEM 2.   PROPERTIES
- -------   ----------

The Company's principal administrative, manufacturing and research operations
occupy approximately 150,000 square feet of leased space in modern buildings
located in Milpitas, California, under leases expiring through 1999.  The
Company's principal healthcare information systems operations occupy
approximately 54,000 square feet of leased space in modern buildings located in
Houston, Texas, under lease expiring in 2002.  Other smaller facilities are
leased in various states and foreign countries.

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


LIQUIDITY AND CAPITAL RESOURCES

Net cash generated by operating activities during fiscal 1995 and 1994 was $5.2
million and $11.9 million, respectively.  Uses of cash in operations were
increases in inventory in anticipation of additional product revenues based on
higher product orders, an increase in accounts receivables as revenues grew
during the second half of fiscal 1995 in relation to that experienced during the
second half of fiscal 1994, and a decrease in accounts payable as the rate of
inventory receipts declined during the later part of the fourth quarter of 1995.
Offsetting these items was cash generated from operating activities primarily
due to increased deferred revenues substantially related to the Company's
service business.

Cash used in investing activities rose substantially to $20.2 million, most of
which was due to the Company's acquisition of Community Health Computing during
fiscal 1995.  Cash generated by financing activities increased $14.4 million
primarily as a result of borrowings used to fund the acquisition.  Additionally,
financing cash inflows increased as a result of $4.0 million in stock option
exercises, employee stock purchases, and dividend reinvestments.

As a result of the above operating, investing and financing activities, the
Company's cash and cash equivalents remained relatively consistent between
fiscal 1995 to 1994 at $7.6 and $7.2 million, respectively.

During fiscal 1995, the Company increased its available lines of credit from
$30.0 million to $40.0 million, of which $18.3 million was outstanding as of the
end of fiscal 1995.

The Company believes that its cash, cash equivalents, cash flows from operating
activities and, if necessary, remaining available lines of credit will be able
to fund the Company's cash flow requirements for the next fiscal year.  On a
longer-term basis, the Company may need to increase its sources of capital in
response to business conditions or to pursue new business opportunities.
Additional borrowings or sale of securities are possible sources.  However,
there can be no assurance that such additional resources of financing will be
available and/or on terms favorable to the Company.

RESULTS OF OPERATIONS

FISCAL 1995 COMPARED TO FISCAL 1994
REVENUES AND GROSS MARGIN:

The Company's two business units are Medical Systems and Healthcare
Information Systems (HCIS).

The Medical Systems business unit includes Nuclear Medicine, Digital Systems
Angiograpghy (DSA), and Radiation Therapy Planning (RTP) equipment products, as
well as customer service related to those products.  Medical Systems product
orders increased from $122.8 million to $142.4 million, while its product
revenues increased from $125.0 million to $129.4 million.   This product revenue
increase was primarily due to a 4.9% or $5.8 million increase in Nuclear
Medicine product sales, which was offset by a $1.5 million decrease in DSA
product sales as that product matured.  Medical Systems service revenues
increased from $36.8 million to $42.0 million, primarily as a result of the
continued increase in the installed product base.

Medical Systems product revenue also represented 94.7% and 92.3% of the
Company's total product revenue during fiscal 1995 and 1994, respectively.
1995's geographical mix of Medical Systems product revenues were 73.3% in North
America, 16.3% in Europe, and 10.4% in the rest of the world, primarily Latin
America and Asia, compared with 1994's 76.7% in North America, 18.3% in Europe,
and 5.0% in the rest of the world.  The mix of product revenues as a percent of
total Medical Systems product revenues for 1995 and 1994 were 95.1% and 93.8%
respectively  for Nuclear Medicine, 2.9% and 4.2% respectively for DSA, and 2.0%
and 2.0% respectively for RTP.

Product backlog for Medical Systems at the end of 1995 was up to $41.5 million,
compared to $28.4 million at the end of 1994.  Unfilled orders may be canceled
or rescheduled by customers in most cases without penalty.  For this reason,
backlog may not be indicative of sales for any succeeding period.

Medical Systems product margins decreased from 42.9% to 37.3%, primarily due to
the continued industry-wide pricing pressures first experienced during the last
half of 1994 as the overall market for Nuclear Medicine products in the United
States declined.  Service margins for Medical Systems increased from 26.2% to
32.5%, as the installed customer base increased, product reliability increased
and overall costs were reduced.

HCIS includes products comprising the hardware, software and related
implementation of systems designed to manage information within the radiology
and laboratory departments of healthcare organizations, as well as service
related to those products. During all of 1994 and most of 1995, the Company's
HCIS product mix included radiology products offered by the Company and
<PAGE>
 
ADAC/SD&G Healthcare Systems (SD&G), which the Company acquired in November
1993.  In July 1995, the Company also acquired Community Health Computing (CHC),
which provided the Company with an additional radiology product, as well as a
laboratory product.  The HCIS business unit now represents the combined
businesses of SD&G, CHC, and the Company's existing radiology business.

Although HCIS product orders remained constant at $12.0 million for both 1994
and 1995,  product revenues declined from $10.5 million to $7.3 million.
Product revenue of $0.8 million was contributed by the acquired CHC business
during 1995.  The decline in HCIS product revenues resulted from reduced sales
of maturing radiology products that were not yet fully offset by sales of newer
radiology products, which are still under development.  HCIS service revenues
increased from $4.0 million to $6.1 million.  The acquired CHC business
contributed $2.8 million of service revenue during 1995.

All HCIS sales are in North America.  For 1995 and 1994, radiology product
revenues represented 91.9% and 100%, respectively, of HCIS product revenues, and
laboratory product revenues represented 8.1% and 0.0%, respectively.

HCIS product backlog increased from $10.4 million to $11.7 million at the end of
1994 and 1995, respectively.  Backlog increased due to backlog acquired upon the
purchase of CHC.  Unfilled orders may be canceled or rescheduled by customers,
in most cases without substantial penalty.  For this reason, backlog may not be
indicative of sales for any succeeding period.

Product margins for HCIS declined from 58.2% to 33.8% due to lower margins
experienced as proprietary third-party hardware platforms were replaced with
non-proprietary open-systems hardware platforms providing lower margins.  In
addition,  laboratory product margins presently are lower during the initial
stages of new product introduction.    HCIS service margins increased from 29.0%
to 49.8% primarily due to obtaining a relatively large installed base of
laboratory product customers when the Company acquired CHC.

OPERATING AND OTHER EXPENSES:

Overall operating expenses as a percentage of revenues decreased from 28.1% to
26.7% excluding 1994's nonrecurring restructuring charges (see "Fiscal 1994
Compared to Fiscal 1993").  This overall expense reduction was a result of the
Company's continued cost reduction efforts started during the second half of
1994 concurrent with the restructuring.  As a percentage of revenue for 1994 and
1995, marketing and sales expenses decreased from 17.3% to 16.2% and research
and development expenses decreased from 6.4% to 5.5%.  Research and development
expenses represent continued investment in new product development and are net
of software capitalization of $2.0 million in 1995 and 
<PAGE>
 
$1.4 million in 1994. General and administrative expenses increased from 4.4% to
4.9%, which was entirely attributable to the acquired CHC business.

Other expense, net, excluding 1994's litigation defense costs and related
settlement (see "Fiscal 1994 Compared with Fiscal 1993 - Operating and Other
Expenses"), increased from $0.2 million to $1.2 million as a result of the
Company carrying short-term bank borrowings during 1995 to fund loans made to
CHC prior to the Company's acquisition of such company and, subsequently, to
fund the acquisition of CHC.

INCOME TAXES:

Fiscal 1995's effective tax rate was 35%, which is approximately equal to the
Company's statutory Federal tax rate after utilization of business tax credits.
In fiscal 1994, the Company recorded a tax benefit resulting from the release of
a valuation allowance against deferred tax assets related to Federal net
operating loss carryfowards (see "Fiscal 1994 Compared to Fiscal 1993 - Income
Taxes").

OTHER:

Segment and foreign operations information is contained in Note 12 of Notes to
Consolidated Financial Statements.

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

In order to maintain successful operating results in the highly competitive
industry in which the Company does business, the Company must continue to
produce innovative products equal to or better than those of its competitors.
Within the industry, there is also uncertainty associated with the potential
response of customers to new private and legislative health care cost
containment initiatives, which may affect the size of marketplace and pricing.
Although the Company has been able to develop and market advanced, innovative
and cost effective new products in recent years, and has been able to increase
its market share in the nuclear medicine industry, there is no assurance that
this will continue.

FISCAL 1994 COMPARED TO FISCAL 1993
REVENUES AND GROSS MARGIN:

The Company's orders and revenues continued to increase in 1994 in all its core
businesses, as well as through the acquisition of SD&G.  Product orders modestly
increased from $135.3 million to $137.8 million.  Product backlog at the end of
1993 and 1994 was $38.9 million and $38.8 million, respectively.

Total product revenues increased 11.8% as a result of an $11.4 million (10%)
increase in Medical Systems product sales and a $3.0 million (40%) increase in
revenues from HCIS products.  The increased sales of HCIS products was 
<PAGE>
 
primarily due to the acquisition of SD&G Healthcare Systems at the beginning of
1994, and represented $10.5 million (7.7%) of total product revenues compared to
$7.5 million (6.2%) of total product revenues in the prior fiscal year. In
Medical Systems, Nuclear Medicine products comprised 85% of the total Company's
product revenues in both fiscal years, of which the Company's GENESYS VERTEX
camera represented the largest percentage component. The increase in MS sales
was particularly strong in Latin America and Europe, with non-domestic revenue
increasing 27.7%. In addition to the Nuclear Medicine products, sales of the DSA
and RTP products also showed modest growth. Service revenues increased 13.9%,
primarily from the expansion of the Company's installed customer base.

Margins on product sales decreased from 48.3% to 42.4% primarily due to
significant pricing pressures as the overall market for Nuclear Medicine
products in the United States declined. Service margins increased from 24.9% to
29.9%.  The increase is attributable to service support costs remaining flat,
despite increased revenue, as the Company focused on cost reduction and
enhancing product reliability.

OPERATING AND OTHER EXPENSES:

Overall operating expenses decreased from 30.4% to 28.1% excluding restructuring
charges. Marketing and sales expenses as a percent of revenue declined from
18.6% to 17.3%. The Company was able to reduce its marketing and sales expenses
as a percentage of revenue while continuing to invest in developing its sales
and marketing efforts in Europe, Asia, and Latin America. While research and
development expenses as a percent of revenue decreased from 7.0% to 6.4%,
research and development expenses increased 1.6% or $0.2 million. The expenses
represent continued investment in new product development and are net of
software capitalization of $1.4 million in 1994 and $0.7 million in 1993.
General and administrative expenses as a percent of revenue decreased from 4.7%
to 4.4%.

Other expense of $6.5 million in 1994 includes $4.2 million in litigation
defense costs and $2.0 million in settlement costs related to the Elscint
litigation as discussed in Note 5 of Notes to Consolidated Financial Statements.
Excluding the litigation defense costs, other expense remained relatively
constant at $0.2 million.

During the third quarter of 1994, the Company implemented a restructuring plan
to eliminate functions and positions dedicated to rework and non-critical
activities, consolidate certain job functions, redesign and streamline
manufacturing systems and processes, and undertake a major program of proactive
and preventive maintenance of the Company's installed base of equipment to
further enhance the equipment's reliability.  As a result, the Company recorded
a restructuring charge of approximately $2.5 million for these 
<PAGE>
 
costs, of which $2.1 million was paid prior to the 1994 fiscal year end. Of the
total restructuring charge, severance and related costs for 67 employees
accounted for 47%, manufacturing redesign 6%, preventive maintenance costs 28%,
asset write-downs 8%, and other costs accounted for the remainder.

INCOME TAXES:

Effective October 4, 1993, the Company adopted Statement of Financial Accounting
Standards (SFAS) No. 109, "Accounting for Income Taxes," as discussed in Note 1
of Notes to Consolidated Financial Statements.   On adoption of SFAS No. 109,
management established a valuation allowance for the entire balance of its net
deferred tax asset due to uncertainty with regard to the outcome of the Elscint
litigation summarized in Note 5 of Notes to Consolidated Financial Statements,
and concerns over healthcare reform legislation.  Following the settlement of
this litigation in September 1994, combined with new legislative developments in
healthcare reform, the valuation allowance against the deferred tax asset was no
longer deemed appropriate in the fourth quarter and therefore was released in
the period.  This resulted in an  income tax benefit of $7.4 million, for a net
income tax benefit for the year of $6.3 million (see Note 11 of Notes to
Consolidated Financial Statements).  This income tax benefit compares to an
effective tax rate in 1993 of 7.5% for the provision for income taxes.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
- ------------------------------------------

NOTE 1 SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Fiscal Year

The Company's fiscal year ends on the Sunday closest to September 30.  Fiscal
1995 and 1994 included 52 weeks compared to 53 weeks in fiscal 1993.

Principles of Consolidation

The consolidated financial statements include the accounts of ADAC Laboratories
and its wholly-owned subsidiaries.  All significant intercompany accounts and
transactions have been eliminated.

Foreign Currency Translation and Transactions

The Company's European subsidiaries' functional currencies are considered to be
their respective local currencies.  Adjustments that arise in translating their
financial statements into the U.S. dollar are included as a separate component
of shareholders' equity in the consolidated balance sheets.

Gains and losses from foreign currency transactions are included as a component
of interest and other income (expense), net,  in the consolidated statements of
income, and amounted to losses of $150, $68, and $73 in fiscal 1995, 1994, and
1993, respectively.

Revenue Recognition

The Company has two major business units for which specific revenue recognition
policies are followed.  Revenues related to the Company's Medical Systems
business unit product sales are recognized upon shipment to the customer or its
requested location, at which time title and risk of ownership passes.  Estimated
provisions for product sale returns, installation and warranty are accrued upon
revenue recognition.  Revenues related to Medical Systems service are recognized
ratably over the relevant contractual period or as the service is performed.
Medical Systems revenue billed but unearned is included on the consolidated
balance sheets as deferred revenue.

Revenues related to the Company's Healthcare Information Systems business unit
are derived from software licenses, computer hardware sales, related
implementation, training and support services and maintenance contracts.
Revenues for software licenses are recognized either at the shipment date or
upon the renewal date if, in either case, payment is due within twelve months
after such date. Revenues for license fees that have payments due beyond twelve
months are generally recognized at the time fees are paid or are billable.
Revenues for computer hardware sales are recognized at the time of shipment. The
Company's obligations subsequent to shipment primarily relate to implementation
and training. Revenues for these services are recognized as the services are
provided. Revenues from maintenance contracts are recognized ratably over the
relevant contractual period.

Research and Development

Research and development expenditures are charged to operations as incurred, net
of certain capitalized software costs.

Income Taxes

Effective October 4, 1993, the Company adopted Statement of Financial Accounting
Standards (SFAS) No. 109, "Accounting For Income Taxes."   Prior to fiscal 1994,
the Company accounted for income taxes under SFAS 96.

Under the asset and liability method prescribed by SFAS No. 109, deferred tax
assets and liabilities are recognized for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases.  Deferred tax
assets and liabilities are measured using enacted tax rates expected to apply to
taxable income in the years in which those temporary differences are expected to
be recovered or settled.  The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

Deferred tax assets are also recognized for deductible temporary differences and
operating loss and tax credit carryforwards and, if appropriate, with a
valuation allowance established against the resulting assets if it is more
likely than not that the related tax benefits will not  be realized.

Income Per Share

Net income per common and common equivalent share has been computed using the
weighted average number of common shares outstanding after considering the
dilutive effect of common stock options and warrants. All per share data has
been adjusted to reflect a one-for-three reverse stock split which was effected
in March 1993.

Cash Equivalents

All highly liquid investments purchased with an original maturity of three
months or less are considered cash equivalents.

Concentration of Credit Risk

The Company sells its products to hospitals and clinics worldwide.  The Company
performs ongoing credit evaluations of its customers and generally does not
require collateral, except for sales within Latin America.  The Company
maintains allowances for potential credit losses and such losses have been
within management's expectations.  The Company invests any excess cash on
deposits with a major bank.  The Company has not experienced any losses on these
deposits.

Inventories

Inventories are stated at the lower of standard cost (which approximates cost on
a first-in, first-out basis) or market.

Service Parts

Service parts used for servicing installed equipment are stated at cost and are
depreciated over a 10-year period using the declining-balance method of
depreciation.

Fixed Assets

Major additions and improvements are capitalized at cost, while maintenance and
repairs which do not improve or extend the life of the respective assets are
expensed as incurred.  When assets are retired or otherwise disposed of, the
costs and related accumulated depreciation are removed from the financial
statements, and any gain or loss on disposal is included in the consolidated
statements of income.  Fixed assets, other than leasehold improvements, are
depreciated on a straight-line basis over their estimated useful lives (3-7
years). Leasehold improvements are amortized on a straight-line basis over the
lesser of their estimated useful lives or the remaining term of the related
leases.

Capitalized Software

Costs related to the conceptual formulation and design of software products are
expensed as product development, and costs incurred subsequent to establishing
the technological feasibility of software products are capitalized.
Amortization of capitalized software costs, which begins when products are
available for general release to customers, is computed using the greater of 1)
the ratio that current gross revenues bear to the total of current and
anticipated future gross revenues; or 2) a straight-line basis over the expected
product lives, generally estimated to be three to seven years.

Software costs capitalized during fiscal years 1995, 1994, and 1993 amounted to
approximately $1,996, $1,402, and $699, respectively. Additionally, $5,802 of
capitalized software was acquired through the acquisition of Community Health
Computing Corporation during fiscal 1995 and $364 of capitalized software was
acquired through the acquisition of SD&G Healthcare Systems, Inc during fiscal
1994 (see Note 3).  Amortization of capitalized software costs amounting to
approximately $1,164, $697 and $584, respectively, have been charged to cost of
product revenues.

Intangible Assets

Goodwill and other purchased intangibles, including technology and sales
partnerships, are capitalized and amortized on a straight-line basis over the
estimated useful life of the related asset (3-15 years).

Reclassifications

Certain reclassifications have been made to prior year financial statements to
conform with the 1995 presentation.

NOTE 3 ACQUISITIONS

On July 12, 1995, the Company completed its acquisition of Community Health
Computing (CHC) of Houston, Texas for approximately $18.4 million, which

The acquisition was accounted for as a purchase, and the results of operations
of CHC have been included in the Company's consolidated financial statements
subsequent to July 12, 1995.  The fair value of assets acquired, including
goodwill, was $27.6 million and liabilities assumed totaled $23.6 million.
Goodwill of $11.9 million is being amortized over 15 years on a straight-line
basis.

On November 16, 1993, the Company acquired SD&G Healthcare Systems, Inc. (SD&G),
a company engaged in the sale and development of hospital information systems.
The Company issued 273 shares of common stock in exchange for all the
outstanding stock of SD&G.  The transaction was accounted for as a pooling of
interests.  The Company also assumed options to purchase SD&G stock which will
remain outstanding as options to purchase approximately 26 shares of the
Company's common stock.   Prior period financial statements have not been
restated because the operations of SD&G were not material to the financial
position or the results of operations of the Company at the time of acquisition.

NOTE 4 CREDIT AND BORROWING ARRANGEMENTS

The Company has revolving credit facilities with two separate banks totaling
$40,000.  Both credit facilities offer borrowings in either U.S. dollars or in
foreign currencies.  One credit facility for $20,000 expires April 5, 1996 and
the other credit facility for $20,000 expires March 31, 1996.  U.S. dollar and
foreign currency borrowings under both credit facilities bear interest at
either Libor plus 1.25% or the bank's base rate.  Borrowings are generally
repaid within 90 days.  No borrowings in foreign currency have been received by
the Company.  At October 1, 1995, the Company had $21,702 available for
borrowing under these facilities.

Borrowings under both facilities are collateralized by the Company's assets, and
the Company is required to comply with certain financial and other covenants,
including restrictions on its ability to acquire or merge with another company,
incur additional debt, or purchase or lease capital assets in excess of $3,000
per year.  In addition, the Company cannot, without prior approval, pay cash
dividends or repurchase common stock in excess of 50% of earnings for the prior
period.

Additional information with respect to such revolving lines of credit is as
follows:

NOTE 5 COMMITMENTS AND CONTINGENCIES

Operating Leases

The Company leases its office and manufacturing facilities under operating
leases which expire at various dates through 2002. The Company is responsible
for maintenance, taxes and insurance on all facilities.

During fiscal 1995, the Company sold and leased back fixed assets with a net
book value of $591 for total proceeds of $832. The gain on the transaction will
be recognized over the five year term of the operating lease.  Similarly, in
September 1994, the Company entered into a sale and leaseback transaction under
which it sold fixed assets with a net book value of $2,809 for total proceeds of
$6,000.  As part of this agreement, the Company entered into two operating
leases over terms of three and five years, respectively.  The gain on the
transaction will be recognized over the terms of the leases.   In addition, the
Company guaranteed to the lessors the final residual value of approximately
$1,012.

As of October 1, 1995, future annual minimum lease payments for all non-
cancelable operating leases are as follows:

</TABLE> 

Payments under these capital lease obligations totaled $126 in fiscal 1995.

As of October 1, 1995, the Company had $729 of equipment under capital leases
with accumulated amortization of $139.

Litigation

In September 1994, the Company settled a lawsuit with Elscint Limited which had
alleged infringement of certain patents relating to Nuclear Medicine imaging and
Digital Fluroscopy technology.  Without admitting any liability or wrongdoing,
the Company agreed to pay $2,000 to settle the lawsuit.  As part of the
settlement, each party agreed not to sue each other with respect to nuclear
medicine intellectual property matters for the next ten years.  This amount was
included in other liabilities in the October 2, 1994 Consolidated Balance Sheet
and was paid on October 4, 1994.  In addition to the $2,000 settlement charge in
fiscal 1994, approximately $4,240 in litigation defense costs were incurred and
are included in other expense in the Consolidated Statement of Income for fiscal
1994.

The Company is also a defendant in other legal proceedings incidental to its
business.  While it is not possible to determine the ultimate outcome of these
other actions at this time, management is of the opinion that any unaccrued
liability resulting from the claims would not have a material adverse effect on
the Company's consolidated financial position or results of operations.

Other

Under third party lease program agreements, the Company is contingently liable
for losses in the event of default by lessees, limited to a percentage (ranging
from 2% to 16%) of the equipment lease, depending on the agreement, and up to
100% for the related service contracts.  At October 1, 1995 the contingent
liability was $1,923.

In conjunction with its third party financing and lease programs, the Company
sells certain receivables with recourse.  The amount of recourse ranges from 10%
to 100% of the receivable.  As of October 1, 1995 the contingent liability was
$4,043.

NOTE 6 CAPITAL STOCK

Preferred Stock

The Board of Directors is authorized to determine the rights and preferences of
the preferred stock, issuable in series.  The Board of Directors may increase or
decrease the number of shares of any series of preferred stock, but not below
the number of shares of such series then outstanding.

Common Stock

In 1994 the Board of Directors approved the issuance of warrants to purchase up
to 60 shares of common stock at the Company's then market price of $6.50 per
share to a consulting firm as partial compensation for services rendered and to
be rendered. The warrants were issued proportionately as services were performed
through March 1995, and expire on July 1, 1999. At October 1, 1995, all of the
warrants related to this issuance had been issued and were outstanding.

As of October 1, 1995, the Company has reserved a total of 2,985 shares of
common stock for issuance under employee stock option plans and 38 under the
employee stock purchase plan as discussed in Note 7.

NOTE 7 STOCK PLANS

Stock Option Plans

The Company currently has three stock option plans for employees and
consultants, including the 1981 stock option plan (under which no further
options may be granted), the 1985 option plan and the 1992 stock option plan,
which was approved by the Board of Directors in July 1992.

The 1985 Option Plan (as amended) and 1992 Option Plan allow for non-qualified
as well as incentive options to be granted to employees, officers, consultants
and others.  Incentive stock options must be granted at exercise prices of not
less than fair market value and expire within 10 years from the date of grant.
Non-qualified stock options can have exercise prices of not less than 85% of
fair market value and also expire within 10 years of grant date.

In addition, the Company has a directors' stock option plan under which options
are granted to non-employee directors. Options under this plan are granted for a
period of 5 years from the date of grant at an option exercise price equal to
100% of fair market value.

Employee Stock Purchase Plan

This plan, as amended, permits eligible employees to purchase common stock
through payroll deductions (which cannot exceed 10% of the employee's
compensation and cannot exceed 100 shares per employee per interim offering
period) at the lower of 85% of fair market value at the beginning of a 27 month
offering period or at the end of each interim period.  Each full-time employee
of the Company who has been employed for six months or more at the commencement
of an interim offering period is entitled to participate in the plan.  During
fiscal years 1995, 1994, and 1993, 58, 57, and 52 shares were issued at an
average price of $7.21, $7.42, and $9.17 per share, respectively.

NOTE 8 RETIREMENT SAVINGS PLAN

The Company maintains a qualified retirement plan, under the provisions of
Section 401(k) of the Internal Revenue Code, in which eligible employees may
participate.  Substantially all participants in this plan are able to defer
compensation up to the annual maximum amount allowable under Internal Revenue
Service regulations.  Additionally, the Company may match employee contributions
with discretionary amounts as may be determined by the Board of Directors.  As
of October 1, 1995, no  matching contributions had been made.

NOTE 9 RESTRUCTURING CHARGES

During the third quarter of 1994, the Company implemented a restructuring plan
to eliminate functions and positions dedicated to rework and non-critical
activities, consolidate certain job functions, redesign and streamline
manufacturing systems and processes, and undertake a major program of proactive
and preventive maintenance of the Company's installed customer base of equipment
to enhance further the equipment's reliability.  As a result, the Company
recorded a restructuring charge of approximately $2.5 million for these costs.
Of the total restructuring charge, severance and related costs for 67 employees
accounted for 47%, manufacturing redesign 6%, preventive maintenance costs 28%,
asset  writedowns 8%, and other costs accounted for the remainder.  At October
1, 1995, the Company had $307 remaining in the restructuring reserve for these
charges.

Note 10 SUBSEQUENT EVENT

On November 9, 1995, the Company acquired JD Technical Services, Inc., of
Washington, Missouri, a leader in nuclear medicine imaging systems
remanufacturing, as well as a nationwide provider of multivendor service and
support. The Company issued 138 shares of common stock at the average closing
price of the Company's common stock during a specified period, for a total price
of $1.7 million, in exchange for all the outstanding stock of JD Technical. The
transaction will be accounted for as a pooling of interests. Prior period
financial statements will not be restated, as the operations of JD Technical
were not material to the financial position or the results of operations of the
Company at the time of acquisition.

Note 11 INCOME TAXES

As discussed in Note 1, the Company adopted SFAS No. 109 as of October 4, 1993.
There was no cumulative effect of this change in accounting for income taxes
determined as of October 4, 1993.  In 1993, the Company accounted for income
taxes under SFAS No. 96.

Income tax expense (benefit) consists of:

As of October 1, 1995, the Company had net operating loss carryforwards of
approximately $15,265 available to offset future federal taxable income and
approximately $6,787 available to offset future taxable income in various
foreign jurisdictions.  Federal tax carryforwards expire in years 1999 to 2000,
and foreign tax carryforwards expire beginning in 1996 and extending
indefinitely.  Net operating loss carryforwards include $15,265 which arose from
the exercise of non-qualified stock options, the tax benefit of which has been
reflected as an increase in paid-in capital of $9.1 million during fiscal 1994.
The Company also has credit carryforwards of $4,585.  These credit carryforwards
will expire in the years 1996 to 2009, if not utilized.

Significant components of the Company's deferred tax assets and liabilities at
October 1, 1995 and October 2, 1994 are as follows:

On adoption of SFAS No. 109 in October 1993, the Company established a valuation
allowance for the entire balance of its net deferred tax asset due to
uncertainty with regards to the outcome of the litigation with Elscint Limited
discussed in Note 5 of the Notes to Consolidated Financial Statements, and
uncertainty of the impact of potential healthcare reform legislation on the
Company's business. Following the settlement of the Elscint litigation in
September 1994 and further developments on healthcare reform, the Company
reassessed the requirement for a valuation allowance under the rules of SFAS No.
109 and concluded that it was more likely than not the deferred tax asset would
be realized and therefore a valuation allowance against its future domestic
income tax loss carryforwards was no longer appropriate. The remaining valuation
allowance at October 1, 1995 and October 2, 1994 relate to net operating loss
carryforwards available for the benefit of foreign operations.

Note 12 SEGMENT INFORMATION AND FOREIGN OPERATIONS

The Company designs, manufactures, and markets medical imaging and health care
information systems to hospitals and clinics worldwide.  During the fourth
quarter of fiscal 1995, the Company completed its acquisition of CHC, as
discussed in Note 3. As a result, the relative significance of the Company's
Healthcare Information Systems' segment increased in relation to the Company's
overall business. Accordingly, the Company's operations are now derived from two
major business units, Medical Systems business (MS) and Healthcare Information
Systems business (HCIS). Prior to 1995, the results of operations from the
Healthcare Information Systems' segment were not significant. The following
table summarizes the results of operations for the Company's two major business
segments.

Additionally, the Company has foreign operations which are those of its
subsidiaries in the Netherlands, France, Germany, Denmark, United Kingdom and
Italy, and substantially all of their sales are made to unaffiliated European
customers. The following table summarizes the foreign subsidiaries' operations:

The sum of a year's quarterly earnings per share may not equal the annual
earnings per share as a result of changes in the outstanding number of shares
during the year and the application of the treasury stock method, which
considers changes in the market price of common stock during each period (see
Note 1, "Income Per Share").

As discussed in Note 12,  during the fourth quarter of fiscal 1995, the Company
completed its acquisition of CHC.  As a result, the relative significance of the
Company's Healthcare Information Systems' segment  increased in relation to the
Company's overall business.  Accordingly, beginning in the fourth quarter of
fiscal 1995, changes were made in the classification of certain income statement
items related to the Company's Healthcare Information Systems' segment.  Total
revenue, operating income, net income, and earnings per share were not affected
by these changes.  Operating expenses of $416, $495, $577 and $610 were
reclassified to cost of sales in the first, second, third and fourth quarter of
1994, respectively, to conform with the revised presentation, as were $107, $702
and $1,337 in the first, second, and third quarter of 1995, respectively.  Prior
to 1994,  the results of operations from the Healthcare Information Systems'
segment were not significant.

Note 14 RECENT PRONOUNCEMENTS

During March 1995, the Financial Accounting Standards Board issued Statement No.
121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of", and in October 1995, the Financial Accounting
Standards Board issued Statement No. 123,  "Accounting for Stock-Based
Compensation".  These pronouncements are effective for the Company's fiscal
1997.  Their adoption is not expected to have a material effect on the financial
statements of the company.

                        REPORT OF INDEPENDENT ACCOUNTS


To the Board of Directors and Shareholders of ADAC Laboratories and Subsidiaries

We have audited the accompanying consolidated balance sheets of ADAC
Laboratories and Subsidiaries as of October 1, 1995 and October 2, 1994, and the
related consolidated statements of income, shareholders' equity and cash flows
for each of the three fiscal years in the period ended October 1, 1995.  These
consolidated 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 audits 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 consolidated financial position of ADAC Laboratories
and Subsidiaries as of October 1, 1995 and October 2, 1994, and the consolidated
results of their operations and their cash flows for each of the three fiscal
years in the period ended October 1, 1995 in conformity with generally accepted
accounting principles.

of the Company under the Note, this Agreement or any other Credit Document, any

without notice, become immediately due and payable without presentment, demand,
protest or notice of dishonor, all of which are hereby expressly waived by the

issue further Letters of Credit hereunder shall immediately cease and terminate;
and (c) the Bank shall have all rights, powers and remedies available under the

time after the occurrence of an Event of Default.  All rights, powers and
remedies of the Bank contained herein or in any other Credit Document are
cumulative and not exclusive and shall be in addition to any other rights,
powers or remedies provided by law or equity.

     9.3  Letters of Credit.  If an Event of Default shall occur, the Bank may,
          -----------------                                                    
at its sole and absolute discretion and in addition 

                                       25
<PAGE>

or any other obligations of the Company to the Bank shall be repaid to the
Company or such other Persons who may be entitled thereto without interest upon
expiration of all Letters of Credit and full satisfaction of all other
obligations owed by the Company to the Bank. The provisions of this Section 9.3

          -------------------------------

     addressed to the Company to such address as the Bank may designate and take

     account has been assigned to the Bank and that all payments are to be made
     directly to the Bank at such address as the Bank may designate; and

          (d) Require the Company to direct all Account Debtors to forward all
     remittances, payments and proceeds of the Collateral directly to the Bank

     checks drafts, money orders or other evidence of payment that may come into
     the Bank's possession.

     9.5  Protection of Security Interest.  If an Event of Default occurs, the
          -------------------------------                                     
Bank may, at its sole and absolute discretion and in addition to any other
remedies available to it hereunder, make such payments and do such acts as the
Bank, in its sole judgment, considers necessary and reasonable to protect its
security interest or lien in the Collateral.  The Company hereby irrevocably
authorizes the Bank to pay, purchase, contest or compromise any encumbrance,
lien or claim which the Bank, in its sole judgment, deems to be prior or
superior to its security interest.  Further, the Company hereby agrees to pay to
the Bank, upon demand therefor, all expenses and expenditures (including
attorneys' fees) incurred in connection with the foregoing.

     9.6  Foreclosure.  If an Event of Default occurs, the Bank may, at its sole
          -----------                                                           
and absolute discretion and in addition to any other remedies available to it
hereunder, enforce any security interest or lien given or provided for under
this Agreement or under any security agreement, mortgage, deed of trust or other
document, in such manner and such order, as to all or any part of the properties
subject to such security interest or lien, as the Bank, in its sole judgment,
deems to be necessary or appropriate and the Company hereby waives any and all
rights, obligations or defenses now or hereafter established by law relating to
the foregoing. In the enforcement of its security interest or lien, the Bank is
authorized to enter upon the premises where any Collateral is located and take
possession of the Collateral or any part thereof, together with the Company's
records pertaining thereto, or the Bank may require the Company to assemble the
Collateral and records pertaining thereto and make such Collateral and records
available to the Bank at a place designated by the Bank. The Bank may sell the
Collateral or any portions thereof, together with all additions, accessions and
accessories thereto, giving only such notices and following only such procedures
as are required by law, at either a public or private sale, or both, with or
without having the Collateral present at the time of the sale, which sale shall
be on such terms and conditions and conducted in such manner as the Bank
determines in its sole judgment to be commercially reasonable. Any deficiency
which exists after the disposition or liquidation of the Collateral shall be a
continuing liability of the Company to the Bank and shall be immediately paid by
the Company to the Bank.

     9.7  Application of Proceeds.  All amounts received by the Bank as proceeds
          -----------------------                                               
from the disposition or liquidation of the Collateral shall be applied to the
Company's indebtedness to the Bank as follows:  first, to the costs and expenses
of collection, enforcement, protection and preservation of the Bank's lien in
the Collateral including court costs and reasonable attorneys' fees, whether or
not suit is commenced by the Bank; next to those costs and expenses incurred by
the Bank in protecting, preserving, enforcing, collecting, liquidating, selling
or disposing of the Collateral; next, to the payment of accrued and unpaid
interest on all of the Loans; next, to the payment of the outstanding principal
balance of the Loans; and last, to the 

                                       27
<PAGE>
 
payment of any other obligations owed by the Company to the Bank. Any excess
Collateral or excess proceeds existing after the disposition or liquidation of
the Collateral will be returned or paid by the Bank to the Company or such other
Persons who may be entitled thereto.

                            -----------------------

     10.1 Compensation for Funding Loss or Expense.  The Company shall pay to
          ----------------------------------------                           
the Bank, upon the request of the Bank, such amount or amounts as shall
compensate the Bank for any loss, cost or expense incurred by the Bank and
promptly reported to the Company as a result of any payment or prepayment of a
LIBOR Loan on a date other than the last day of an Interest Period.  A
certificate of the Bank shall be conclusive, except in the case of manifest
error, as to the amount of such loss, cost or expenses due to the Bank in
accordance with this Section.  If for any reason any such certificate is
delivered after the prepayment or payment by acceleration to which such
certificate relates, the Company promptly upon receipt of the certificate shall
pay to the Bank the amount set forth therein.

     10.2  Illegality.  If after August 6, 1993, the adoption of any applicable
           ----------                                                          
law, rule or regulation, or any change therein, or any change in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by the Bank with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency shall make it unlawful or impossible for any Bank to make, maintain or
fund LIBOR Loans, the Bank shall forthwith give notice thereof to the Company
whereupon until the Bank notifies the Company that the circumstances giving rise
to such suspension no longer exist, the obligation of the Bank to make LIBOR
Loans shall be suspended and outstanding LIBOR Loans shall be converted to Base
Rate Loans.

     10.3 Taxes.
          ----- 

          (a) All payments made under this Agreement, the Note and the other
     Credit Documents shall be made free and clear of, and without set-off or
     counterclaim for or on account of, any present or future taxes levies,
     imposts, duties, deductions, withholdings, fees, liabilities and similar
     charges (collectively, the "Taxes") imposed by any government or any
     political subdivision or taxing authority thereof (other than taxes based
     solely on the overall net income of the Bank); provided, however, that such
     payments may be reduced by the amount of United States Federal income taxes
     required to be withheld by the Company with respect to any payment of
     interest to the extent that such withholding does not exceed such taxes
     which would be required to be 

                                       28
<PAGE>
 
     withheld if such interest were paid on August 6, 1993. If the Company is
     prevented by operation of law or otherwise from paying, causing to be paid,
     or remitting that portion of interest represented by Taxes withheld or
     deducted, then interest payable under this Agreement, the Note and the
     other Credit Documents will be increased to such amount as is necessary to
     yield and remit interest to the Bank at the applicable rate specified in
     Article 2 after provision for payment of such Taxes (other than as provided
     in the immediately preceding sentence). The Company will execute and
     deliver to the Bank at its request such further instruments as may be
     necessary or desirable to give full force and effect to such increase in
     the rate of interest, including but not limited to, a new Note of the
     Company to be issued in exchange for any Note theretofore issued. The
     Company will also hold the Bank harmless and indemnify it for any stamp or
     other taxes with respect to the preparation, execution, delivery,
     performance or enforcement of this Agreement, the Note or the other Credit
     Documents. If any of the Taxes required to be paid by the Company are not
     paid by the Company and are paid by the Bank, the Company will, upon demand
     of the Bank, reimburse the Bank for such payments, together with any
     interest penalties and expenses in connection therewith, plus interest
     thereon at a rate equal to 1% per annum over the cost to the Bank (as
     determined by the Bank) of funds acquired by it to pay the same, from the
     date such payment is made to the date of reimbursement by the Company. With
     respect to any deduction or withholding pursuant to this Section, the
     Company shall promptly (but in no event later than thirty (30) days
     thereafter) furnish to the Bank upon its request such certificates,
     receipts and other documents as may be required to establish any tax credit
     to which the Bank may be entitled.

          (b) In the event that any change in applicable law or regulation or in
     the interpretation or administration thereof by any governmental authority
     charged with the administration thereof subjects the Bank to any tax, levy,
     impost, duty, charge, fee, deduction or withholding of any kind whatsoever
     with respect to this Agreement, the Note or the other Credit Documents, or
     changes the basis of taxation of payments to the Bank of principal or
     interest payable on the Note or the other Credit Documents (other than any
     tax on the overall net income of the Bank) or imposes, modifies or deems
     applicable any reserve requirement against assets held by or deposits in or
     for the account of, or loans by, the Bank or imposes on the Bank, directly
     or indirectly, any other conditions affecting this Agreement, the Note or
     the other Credit Documents, and the result of any of the foregoing is to
     increase the cost to the Bank of maintaining the Loans by an amount which
     the Bank deems to be material in relation to the Loans, the Letters of
     Credit or the Guaranties or interest thereon, then the Company shall pay
     such additional costs to the Bank immediately upon its 

                                       29
<PAGE>
 
     demand; provided, however that the Company shall not be liable for
     additional costs hereunder in the event that it immediately prepays all the
     Loans and all other obligations in full, in accordance with Article 3 of
     this Agreement.

     10.4 Reserve Requirements.  It is understood that the cost to the Bank in
          --------------------                                                
making or maintaining a LIBOR Loan may fluctuate as a result of the
applicability of or changes in reserve requirements imposed by the Board of
Governors of the Federal Reserve System of the United States, including but not
limited to reserve requirements under Regulation D of such Board of Governors in
connection with Eurocurrency Liabilities at the ratios provided for in
Regulation D from time to time.  The Company agrees to compensate the Bank for
such costs of making or maintaining the LIBOR Loans made by it resulting from
such reserve requirements since it is understood by the parties hereto that the
rates of interest applicable to LIBOR Loans under this Agreement have been
determined on the hypothetical assumption that no such reserve requirements
exist or will exist and that such rates do not reflect costs imposed on the Bank
in connection with such reserve requirements.  Both parties to this Agreement
acknowledge that as of the Effective Date, the reserve requirement is zero.

     10.5  Notice Certificates.  The Bank shall deliver to the Company from time
           -------------------                                                  
to time one or more certificates setting forth the amounts due to the Bank under
this Article 10 and the method the Bank used to compute such amounts.  Each such
certificate shall be conclusive in the absence of manifest error.  The Company
shall pay to the Bank the amounts shown as due on each such certificate within
ten Business Days of its receipt of same (except as otherwise indicated for the
certificate sent under Section 10.1).  No failure on the part of the Bank to

("the judgment currency") an amount due in Dollars, then the conversion shall be
made at the rate of exchange prevailing at the close of business on the Business
Day before the day on which the judgment is given.  If there is a change in the
rate of exchange prevailing between the Business Day before the day on which the
judgment is given and the date of payment of the amount due, the Company will
pay such additional amounts (if any) as may be necessary to ensure that the
amount paid in the judgment currency when converted at the rate of exchange
prevailing on the date of payment will produce the amount then due under this
Agreement in Dollars and the Bank will apply any additional amounts (if any)
over the amount then due under this Agreement in Dollars that the Bank receives
as a result of such conversion to any other obligations owed by the
Company to the Bank and, if all obligations of the Company to the Bank are fully
satisfied, shall pay any excess to the Company or such other Persons who may be

herewith or therewith, the consummation of the transactions contemplated hereby

Agreement, any Credit Document, and any such other documents, including the

plead any statute of limitations as a defense to any demand hereunder.

enforceable obligations in accordance with the terms thereof based on an actual
and bona fide sale and delivery or lease of equipment or extension of credit to
the named Customer which has been finally accepted by the Customer and for which
the Customer is unconditionally liable to make payment in the amount stated in
the Contract without right of rejection, return, offset, defense, counterclaim,
discount or deduction;

         3.4.5.   The transactions underlying or giving rise to the Contracts
and the sale, delivery or assignment thereof by ADAC to DVI are in conformity
with and do not violate any applicable U.S. state or federal laws or regulations
and all documents constituting, securing or relating to the Contracts are
legally sufficient and enforceable under such laws and regulations of the
countries of the Customers under the Financed Contracts.

         3.4.6.   ADAC will use its best efforts to make all necessary filings,
recordings, or give notice and obtain all necessary waivers and consents so as
to enable DVI to obtain judgment against the Customer for the unpaid balance of
the Contract and for ADAC to exercise the rights of a seller retaining title or
a secured party as to the Equipment;

         3.4.7.   ADAC will not, without the prior written consent of DVI,
accept any collections, repossess or consent to the return of any Equipment or
modify the terms of any Contract;

         3.4.8.   Any down payment set forth in the Contracts was made in cash
and no part of it was advanced to the Customer by ADAC or any assignor; and

         3.4.9.   Any related amendment, addendum, schedule, rider, supplement,
agreement or instrument entered into with the Customer and any other documents
relating to the Contract or Equipment has been delivered to DVI including,
without limitation, Bills of Lading.

         3.4.10.  The Contracts require that the Equipment is and will continue

hazards and ADAC shall be named as loss payee under such policy as ADAC's
interests may appear and ADAC hereby assigns its right, title and interest in
and to said insurance policies and any proceeds therefrom to DVI.

4.   TERM OF AGREEMENT AND AMOUNT OF COMMITMENT; RENEWAL

     4.1.   Term.  The Term of this Agreement is for a period of one (1) year
            ----                                                        
from the effective date hereof, and thereafter will be automatically renewed for
successive one (1) year terms unless

                                       4
<PAGE>
 
either party elects to terminate this Agreement by giving notice in writing to
the other party of its intention to terminate thirty (30) days prior to the end
of the then current Term; PROVIDED HOWEVER, that DVI shall have the right to
immediately terminate this Agreement by giving notice to ADAC upon the
occurrence of an Event of Default as defined in Section 17 below.

     4.2.   Commitment Amount.  Subject to the terms and conditions of this
            -----------------                                              
Agreement, and during the Initial Term of this Agreement, DVI agrees to purchase
Obligations from ADAC up to the aggregate principal sum of Five Million Dollars
($5,000,000).  At such time as DVI has completed the purchase of the initial
Five Million Dollars ($5,000,000) of Obligations, DVI in its sole discretion may
increase the Commitment Amount.

5.   ADMINISTRATION OF CONTRACTS

     Until the happening of an Event of Default hereunder DVI authorizes ADAC or
its agent, and ADAC agrees, as agent for DVI, to bill for and collect all monies
due and to become due under the Financed Contracts and to make all appropriate
efforts, by suit or otherwise, at ADAC's own cost and expense, subject at all
times to DVI's right to direct and control the same. In connection therewith,
ADAC agrees that ADAC may (a) obtain and enter judgments against Customers and
undertake all proceedings supplementary thereto for the purpose of enforcing
such judgments and (b) subject to Section 13 of this Agreement, repossess,
resell, re-lease or otherwise dispose of the Equipment. ADAC agrees to exercise
due care and diligence in so acting as DVI's agent and to indemnify and hold DVI
harmless from and against all loss, liability (including negligence, tort and
strict liability), damage, costs and expenses (including reasonable attorney's
fees) caused by any of ADAC's actions and will not, without DVI's prior written
consent, grant any extension of time of payment, compromise or settle for less
than the full amount owing, or release in any manner Customers or any other
persons liable for payment under any Financed Contract. ADAC agrees to direct
any Customer under any Financed Contract to remit all Installment Payments
directly to a demand deposit account designated by DVI entitled "ADAC Latin
American Finance" which account shall be owned and controlled solely by DVI.

          ADAC agrees that it will not direct any Customer under any Financed
Contract to make payment to any other place or address without DVI's prior
written consent.  Any payments received by ADAC under any Financed Contract will
be held by ADAC in trust for DVI even though the same may have been commingled
with ADAC's assets as a convenience to ADAC and ADAC agrees to remit all such
funds received by it to DVI immediately upon receipt by ADAC.

6.   SERVICE BY ADAC

     ADAC agrees promptly to fulfill all of its obligations to the Customers
with respect to the Equipment. The purchase of the Contract and Obligations by
DVI shall not be deemed an assumption by DVI of, or impose on DVI, any
obligation with respect to the Customer or the Equipment. ADAC shall provide
customer service and Equipment maintenance equivalent to that provided to ADAC's
other customers whether purchasers or Customers. Such service shall be provided
at ADAC's billing rates then in effect and include, but not be limited to,
hardware and software maintenance, required engineering changes to the
Equipment, customer training and program support.

any Contract financed under this Agreement shall be subject to (i) warranties

     10.2.   Design Changes.  Engineering design changes and configuration
             --------------                                               
changes, including software, which improve performance or extend product life
will be made available to Customers on the same basis as other End Users and at

     10.3.   Spare Parts.  ADAC will maintain or require its suppliers to

<PAGE>
 
Equipment, or with this Agreement, or with any Financed Contract, including,
without limitation, claims for injury to or death or persons and for damage to
property, and to give DVI prompt notice of any such claim or liability excluding
any of the same arising from the negligence or willful misconduct of DVI, and
provided that ADAC shall be given prompt notice of such claims and ADAC shall
have the right to defend any such claims, at ADAC's expense.

12.  ADAC FIRST LOSS RECOURSE POOL

     12.1.   Calculation of First Loss Recourse Pool, Limited Recourse. The
             ---------------------------------------------------------  
First Loss Recourse Pool ("Pool") will be established at the time DVI first
purchases a contract from ADAC.  No actual fund shall be established with
respect to the Pool.  ADAC shall, upon written request of DVI, pay to DVI the
amount of Remarketing Loss arising as a consequence of any events set forth in
Section 12.2, provided that ADAC shall not at any time be required to pay an
amount exceeding the then amount of the Pool.  All claims due DVI shall be
payable to DVI by ADAC in U.S. dollars via check or wire transfer within five
(5) days of the request for payment.  The amount of the Pool will increase or
decrease as follows:

     Ten percent (10%) of the Purchase Price of each new Financed Contract
shall be added to the Pool.  However, the Pool shall at no time become greater
than fifteen percent (15%) (the "Ceiling Percentage") of the Net Investment
Value of the then outstanding Financed Contracts.  (If reductions in Net
Investment Value of the outstanding Financed Contracts cause the Pool to exceed
the Ceiling Percentage, the Pool will be reduced accordingly.)  Any Remarketing
Loss shall reduce the Pool by the amount of the Remarketing Loss.  The foregoing
calculation is subject to the further adjustment that at such time as the Pool
becomes $150,000 or less, the Pool shall not be further reduced by amortization
of the outstanding Financed Contracts.

     DVI and ADAC shall jointly prepare each month during the term of this
Agreement a calculation of First Loss Recourse Pool in the form attached as
Exhibit A to this Agreement.

     Except for breaches by ADAC of warranties, representations and covenants
given and agreed to by ADAC in this Agreement, and for indemnities provided by
ADAC hereunder to which this limited recourse provision does not apply, DVI will
not at any time have recourse to ADAC, personally or to its assets, for an
amount exceeding the then amount of the Pool, but rather DVI shall have recourse
only to the Financed Contracts and its security interest in the Equipment for
repayment of the Obligations.

         12.1.1.   Adjustments to Recourse Pool.  ADAC and DVI agree to annually
                   ----------------------------                        
analyze the performance of the Portfolio beginning eighteen (18) months from the
date the first Contract is

                                       8
<PAGE>
 
purchased by DVI.  If at such time the Default Rate is less than one percent
(1%) the Ceiling Percentage will be decreased to ten percent (10%); if the
Default Rate is between one percent (1%) and  three percent (3%) inclusive the
Ceiling Percentage will remain at fifteen percent (15%); and if the Default Rate
is greater than three percent (3%) the Ceiling Percentage will increase to
twenty percent (20%).  The Default Rate at any time will be determined by
dividing (x) the then Net Investment Value of those outstanding Financed
Contracts having delinquencies of more than thirty (30) days by (y) the
aggregate Net Investment Value of the Portfolio.

     12.2.   Amounts Payable from and Credits to Recourse Pool.  The Recourse
             -------------------------------------------------      
Pool shall be charged by DVI for the amount of any Remarketing Loss and said
amount shall be payable by ADAC immediately upon the occurrence of any of the
following events: (i) a Remarketing Loss under a Financed Contracts exists
following the resale of repossessed Equipment related to such Financed Contract;
(ii) an item of Equipment that has been repossessed from a Customer is
determined to be non-saleable by agreement between DVI and ADAC, (iii) DVI and
ADAC are unable to resell repossessed Equipment within one hundred and twenty
(120) days after date of repossession, or (iv) ADAC is unable to take possession
of the Equipment within one hundred and twenty (120) days from the date of DVI's
written request for repossession. In the event that either event (iii) or event
(iv) above occurs and ADAC or DVI is able to remarket the repossessed Equipment
after the initial one hundred and twenty (120) day period, any proceeds from the
remarketing payable to ADAC, up to an amount equal to the amount charged to the
Recourse Pool, shall be credited to the Recourse Pool. Any amount in excess of
the Recourse Pool amount shall be allocated as set forth in Section 13.3.

13.  REPOSSESSION AND REMARKETING

     ADAC shall have the following obligations:

     13.1.   ADAC's Obligation to Repossess and Remarket.  ADAC at its cost
             -------------------------------------------                   
agrees to use reasonable efforts to repossess the Equipment under any defaulted
Financed Contract and said obligations shall continue for the entire term of
said Contract respecting such Equipment, notwithstanding the termination or
expiration of this Agreement and without regard to any extension or non-
extension of this Agreement; provided however, that ADAC shall not be required
to take legal action to effect collection or repossession of any Equipment.  If
DVI reasonably believes that any Financed Contract is unenforceable, upon the
request of DVI, ADAC shall proceed, at its sole expense, to take legal action to
enforce the terms of the Financed Contract.  If a court of competent
jurisdiction determines that the Financed Contract is not enforceable against
the Customer in accordance with its terms, upon the request of DVI, ADAC shall
repurchase the Financed Contract from DVI for the Purchase Price set forth in
Section 18.2 of this

                                       9
<PAGE>
 
Agreement.  In situations where circumstances make immediate recovery of the
Equipment necessary and DVI has requested same, ADAC shall use all reasonable
efforts necessary to obtain the Equipment on an expedited basis.  If the
Equipment cannot be repossessed, DVI may charge the Recourse Pool in accordance
with Section 12 above.

     13.2.  Obligation to Remarket.  In the event that a Customer should
            ----------------------                                      
default in the payment or performance of any of the terms or conditions of any
Financed Contract, ADAC shall, subject to DVI's instructions to the contrary, at
ADAC's expense, attempt to peaceably take possession of, transport, store,
repair or refurbish, if necessary and maintain  the Equipment on behalf of DVI.
ADAC agrees to use its best efforts to locate a purchaser or substitute Customer
for the Equipment on terms satisfactory to DVI.

         13.2.1.   Upon resale, the equipment shall carry ADAC's regular
warranty for a period equal to the greater of:  (i) the warranty remaining for
the benefit of the defaulting Customer as of the date of recovery by ADAC, or
(ii) six (6) months.

     13.3.   Remarketing Proceeds.  Remarketing Proceeds shall mean the
             --------------------                                      
gross proceeds of resale or re-lease of any Equipment.  The gross proceeds of
any re-lease of Equipment shall be calculated on a present value basis using the
formula set forth in the definition of Purchase Price.  Any Remarketing Proceeds
in excess of the Net Investment Value realized upon any sale or releasing of any
Equipment shall be divided between DVI and ADAC as follows:  ten percent (10%)
to DVI, ninety percent (90%) to ADAC.

     13.4.   Remarketing Loss.  Losses as a result of repurchase, repossession
             ----------------                                    
and remarketing shall be determined as the excess of (i) the then Net Investment
Value of the Financed Contract over (ii) Remarketing Proceeds with respect to
such Financed Contract.

     13.5.   Remarketing Expenses  All costs, fees and expenses of remarketing
             --------------------                                 
or refurbishing the Equipment shall be borne solely by ADAC.

14.  GENERAL ADMINISTRATIVE PROVISIONS

     14.1.   Site of Equipment and Inspection.  Unless otherwise approved by

                      ------------------------------------


     THIS AGREEMENT AND PLAN OF REORGANIZATION, dated as of November 9, 1995
(the "Agreement"), is made by and among ADAC LABORATORIES, a California
corporation ("ADAC"), ADAC ACQUISITION, INC., a Delaware corporation and a
wholly-owned subsidiary of ADAC ("SUBSIDIARY"), J.D. TECHNICAL SERVICES, INC., a
Missouri corporation ("J.D. TECHNICAL") and  David Sutton and Jerome W.
Pepmueller, the sole shareholders of J.D. Technical (each, "J.D. TECHNICAL
SHAREHOLDER" and collectively, the "J.D. TECHNICAL SHAREHOLDERS").

     WHEREAS, the Boards of Directors of ADAC and Subsidiary and the
shareholders of J.D. Technical have approved the merger of J.D. Technical and
Subsidiary (the "MERGER"), upon the terms and subject to the conditions set
forth herein; and
 
     WHEREAS, by executing this Agreement, the parties hereto intend to adopt a
plan of reorganization within the meaning of Section 368(a)(1)(A) of the
Internal Revenue Code of 1986, as amended (the "CODE");

     NOW, THEREFORE, in consideration of the premises and of the mutual
agreements, provisions and covenants herein contained and in order to set forth
the terms and conditions of the Merger and the mode of carrying the same into
effect, the parties hereto hereby agree as follows:

                                   ARTICLE I

                                   THE MERGER

     1.1  SURVIVING CORPORATION.  Subject to and in accordance with the terms
          ---------------------                                              
and conditions of this Agreement and the General and Business Corporation Law of
Missouri (the "MISSOURI CORPORATION LAW") and the Delaware General Corporation
Law ("DELAWARE CORPORATION LAW"), at the Effective Time (as defined in Section
                                                                       -------
1.4 hereof), J.D. Technical shall be merged with and into the Subsidiary, in
- ---                                                                         
accordance with the applicable provisions of the laws of the States of Missouri
and Delaware and the separate existence of J.D. Technical shall thereupon cease,
and the Subsidiary shall be the surviving corporation (hereinafter sometimes
called the "SURVIVING CORPORATION") and shall continue its corporate existence
under the laws of the State of Delaware.  For purposes of this Agreement,
Subsidiary and J.D. Technical are sometimes referred to as the "CONSTITUENT
CORPORATIONS."

     1.2  ARTICLES OF INCORPORATION AND BYLAWS.  From and after the Effective
          ------------------------------------                               
Time, the Articles of Incorporation and Bylaws of the Surviving Corporation, as
in effect immediately prior to the Effective Time, shall continue in full force
and effect as the Articles and Bylaws of the Surviving Corporation until amended
from time to time as provided therein or by law.

     1.3  EFFECTIVE TIME.  The Merger shall become effective at the
          --------------                                           
<PAGE>
 
time of filing with the Delaware Secretary of State of a Certificate of Merger
(the "CERTIFICATE OF MERGER") in form satisfactory to the parties which filing
shall be made on the Closing Date (as defined in Article VII hereof) or as soon
as practicable thereafter.  The date and time when the Merger shall become
effective is herein referred to as the "EFFECTIVE TIME."  The parties shall
cause a conformed copy of the Certificate of Merger or Articles of Merger to be
filed with the Missouri Secretary of State and any additional documents to
effect the Merger.

     1.4  EFFECTS OF THE MERGER.  The Merger shall have the effects prescribed
          ---------------------                                               
by the Delaware Corporation Law and Missouri Corporation Law, including without
further transfer, act or deed, the separate existence of J.D. Technical shall
cease and the Surviving Corporation shall possess all of the rights, privileges,
powers and franchises, and shall be subject to all of the restrictions,
disabilities and duties of J.D. Technical, and all property, real, personal and
mixed, and all debts due to J.D. Technical on whatever account shall be vested
in and become the property of the Surviving Corporation, and the title to any
real estate vested by deed or otherwise, if any, in J.D. Technical shall not
revert or be in any way impaired by reason of the Merger; and all rights of
creditors of J.D. Technical and all liens upon any property of J.D. Technical
shall be preserved unimpaired and all debts, liabilities and duties of J.D.
Technical shall thenceforth attach to the Surviving Corporation and may be
enforced against it to the same extent as if such debts, liabilities and duties
had been directly incurred or contracted by it.

     1.5  CONVERSION OF J.D. TECHNICAL SHARES.  At the Effective Time:
          -----------------------------------                         

          (a)  The conversion of shares of Common Stock of J.D. Technical (the
"J.D. TECHNICAL COMMON STOCK") into shares of ADAC Common Stock (the "ADAC
COMMON STOCK") shall occur automatically at the Effective Time without any
further action by the holders thereof.  Subject to a holdback of ADAC Common
Stock pursuant to Section 8.2 hereof, J.D. Technical Common Stock shareholders
                  -----------                                                 
shall receive that aggregate amount of shares of ADAC Common Stock determined by
dividing $1,700,000 by $12.292, being the average closing price (rounded to the
third decimal place) of ADAC Common Stock during the three (3) consecutive
trading days (November 2 [$12-1/8], November 3 [$12-1/2] and November 6 [$12-
1/4]) as reported in The Wall Street Journal ending two (2) trading days prior
                     -----------------------                                  
to the date of execution of this Agreement by all of the parties hereto (the
"PER SHARE PRICE"). Subject to such holdback of ADAC Common Stock pursuant to
Section 8.2 hereof, each J.D.
- -----------

<PAGE>
 
Technical Shareholder shall receive from the aggregate number of shares of ADAC
Common Stock to be distributed a proportionate pro-rata number of shares based
on the number of shares of J.D. Technical Common Stock held by such shareholder
as compared to all of the issued and outstanding J.D. Technical Common Stock.

          (b)  To the extent any J.D. Technical Shareholder would otherwise be
entitled to receive a fraction of a share of ADAC Common Stock, such holder
shall instead receive a full share of ADAC Common Stock.

          (c)  As a condition to receiving the ADAC Common Stock, each J.D.
Technical Shareholder shall execute and deliver to ADAC and the Surviving
Corporation an investment letter substantially in the form attached hereto as
Exhibit A.   Pursuant to Section 4.6 ADAC will use its best efforts to cause the
- ---------                -----------

          --------------                                                      
of reorganization and to consummate the Merger in accordance with Section
368(a)(1)(A) of the Code.  Each J.D. Technical Shareholder is urged to consult
with his or her own tax advisor or accountant as to the personal tax
consequences, if any, resulting from the Merger.  J.D. Technical Shareholders
will be solely responsible for any tax consequences resulting to them from this
Merger, the cancellation of their shares of J.D. Technical Common Stock and
their receipt of shares of ADAC Common Stock.

     1.7  DELIVERY OF ADAC COMMON STOCK.   At or immediately after the Effective
          -----------------------------                                         
Time each J.D. Technical Shareholder will surrender his or her respective stock
certificates representing the J.D. Technical Common Stock extinguished in the
Merger, and, subject to Section 8.2 hereof, ADAC will deliver to the J.D.
                        -----------                                      
Technical Shareholders entitled thereto stock certificates representing ADAC
Common Stock, duly registered in the name of each such J.D. Technical
Shareholder, with restrictive legends as may be required under the Securities
Act.  Such delivery shall occur within ten (10) business days after the
Effective Time or otherwise in accordance with the practices of ADAC's transfer
agent.

     1.8  FURTHER ASSURANCES.  If at any time after the Effective Time, the
          ------------------                                               
Surviving Corporation shall be advised that any deeds, bills of sale,
assignments or assurances or any other acts or things are necessary, desirable
or proper to vest, perfect or confirm its right, title or interest in, to or
under any of the 

                                       3
<PAGE>
 
rights, properties or assets of J.D. Technical acquired or to be acquired as a
result of the Merger and otherwise to carry out the purposes of this Agreement,
the Surviving Corporation and its officers are hereby authorized to execute and
deliver, in the name of J.D. Technical all such deeds, bills of sales and other
documents and to take such other action as necessary to vest, perfect and
confirm its right, title and interest in the properties and assets acquired
pursuant to the Merger.

     1.9  CONSUMMATION OF MERGER.  The parties desire to consummate the closing
          ----------------------

State a duly executed and verified Certificate of Merger and to the Missouri
Secretary of State a duly executed and verified Articles of Merger and the
parties shall take all such other and further actions as may be required by law

     1.10 SPIN-OFF OF REDI-VU PRODUCT LINE.  At or prior to the Closing Date of
          --------------------------------                                     
this Agreement, J.D. Technical shall transfer all of its products and assets and
liabilities relating to its Redi-Vu Systems business or products line, as set
forth on Schedule 1 attached hereto (collectively, the "REDI-VU BUSINESS"), to
         ----------                                                           
the J.D Technical Shareholders or their affiliates.  Such transfer shall be
without representation or warranty, expressed or implied, by J.D. Technical and
shall be received on an "AS IS" basis.  At the time of such transfer of the
Redi-Vu Business, the J.D. Technical Shareholders represent and warrant that (i)
the assets constituting the Redi-Vu Business shall constitute less than 10% of
the total assets of J.D. Technical prior to such transfer, both in terms of
historical costs and fair market value, (ii) the sales generated or associated
with the Redi-Vu Business during the prior twelve (12) months shall constitute
less than 10% of the gross sales of all of the products and services sold by
J.D. Technical during such period, and (iii) the sales generated or associated
with the Redi-Vu Business during the prior twelve (12) months shall have
generated less than 10% of the gross operating profits of J.D. Technical derived
from the sale of all of its products and services during such period.  The J.D.

The number of shares of ADAC Common Stock being held for security of any
indemnification obligations of the J.D. Technical Shareholders pursuant to
Section 8.2 hereof shall be included under the Registration Statement, but shall
not be released from the holdback until the time limitations set forth in

Technical Shareholders such number of copies of a prospectus, including a
preliminary prospectus, in conformity with the requirements of the Securities
Act, and such other documents as they may reasonably request in order to
facilitate the disposition of the Registrable Securities owned by them.  All
expenses incurred in connection with such registrations shall be borne by ADAC,
except the J.D. Technical Shareholders shall bear all commissions and similar
expenses.  It shall be a condition precedent to the obligations of ADAC to take
any action pursuant to this Subsection that the J.D. Technical Shareholders
shall furnish to ADAC such information regarding them, the Registrable
Securities held by them and the intended method of disposition thereof as ADAC
shall reasonably request and as shall be required in connection with the action
to be taken by ADAC.

violation by J.D. Technical of the terms of this Agreement;

November 16, 1995, if, by that date, the conditions set forth in Article VI

warranties shall expire on November 9, 1996, except with respect to claims made
in writing by one party against the other during such time period pursuant to
the Escrow Agreement.

          -----------                                                          
this Agreement, or the breach thereof, shall be settled by a three-person panel
of arbitrators in an arbitration conducted in Denver, Colorado, in accordance
with the Commercial Arbitration Rules of the American Arbitration Association
("AAA") as such rules shall be in effect on the date of delivery of demand for
arbitration.

          Judgment upon the award rendered by the arbitrators may be entered in
any court having jurisdiction thereof.  The arbitrators' decision shall be in
writing and shall be final and nonappealable.  The arbitrators' authority shall
include ordering discovery proceedings and the ability to render equitable types
of relief and, in such event, any aforesaid court may enter an order enjoining
or compelling such actions as found by the arbitrators.  The arbitrators shall
also make a determination regarding whether one party's legal position in any
such controversy or claim is the more substantially correct (the "Prevailing
Party") and the arbitrators shall require the other party or parties to pay the
reasonable legal and other professional fees and costs incurred by 

                                       26
<PAGE>
 
the Prevailing Party in connection with such arbitration proceeding and any
necessary court action. The parties recognize and agree that the remedy of
specific performance may be appropriate in order to enforce certain provisions
of this Agreement. The parties agree that a party would be entitled to pursue
such remedies for emergency or preliminary injunctive or other equitable relief
in any court of competent jurisdiction, provided that there would be a stay of
such judicial proceedings on the merits of the dispute arising out of or
relating to this Agreement pending arbitration of all underlying claims between
the parties immediately following the issuance of any such emergency or
preliminary injunctive or other equitable relief.

          The arbitrators shall be chosen from a list provided by the AAA as
follows:  one arbitrator shall be chosen directly by ADAC, one arbitrator shall
be chosen directly by the J.D. Technical Shareholders, and the third arbitrator
shall be selected by the two arbitrators so chosen.

     9.9  COUNTERPARTS.  This Agreement may be executed in two or more
          ------------                                                
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

     9.10 SEVERABILITY.  If any provision of this Agreement, or the application
          ------------                                                         
thereof to any person or circumstance, should, for any reason and to any extent,
be invalid or unenforceable, the remainder of this Agreement and the application
of such provision to other persons or circumstances shall not be affected
thereby, but rather shall be enforced to the greatest extent permitted by law.

J.D. TECHNICAL
  SHAREHOLDER:      Jerome Pepmueller

SECURITIES:         Common Stock

================================================================================


     In connection with the merger of J.D. Technical Service, Inc. ("J.D.
Technical") and ADAC Acquisition, Inc. ("Acquisition") pursuant to that certain
Agreement and Plan of Reorganization (the "Agreement"), I understand that I will
receive shares of Common Stock (the "Securities") of ADAC Laboratories, a
California corporation ("ADAC"), and, as a condition to receiving such
Securities, the undersigned hereby represents to Acquisition and ADAC the
following:

     (a)  I have received copies of ADAC's Annual Report on Form 10-K for the
fiscal year ended October 2, 1994, and Quarterly Reports on Form 10-Q for each
fiscal quarter of the 1995 fiscal year.

     (b)  I understand and acknowledge that the initial issuance of the
Securities pursuant to the Agreement will not be registered under the Securities
Act of 1933, as amended (the "Securities Act"), on the grounds that the
issuances of these Securities are exempt from registration pursuant to Section
3(b) or Section 4(2) of the Securities Act or Regulation D promulgated
thereunder, and that ADAC's reliance upon such exemption is predicated upon my
representations contained herein.

     (c)  I am aware of ADAC's business affairs and financial condition and I
have acquired sufficient information about ADAC to reach an informed and
knowledgeable decision.  I have been given an opportunity to ask questions of
management of ADAC concerning the the terms and conditions of the merger, the
Agreement, the Securities and the business and financial condition of ADAC.
<PAGE>
 
     (d)  I am acquiring these Securities for my own account (or a trust account
if the undersigned is a trustee) for investment purposes only and not with a
view to, or for the resale in connection with, any "distribution" thereof in
violation of the Securities Act of 1933, as amended (the "Securities Act").  I
am able to fend for myself in connection with the purchase of the above
Securities and I have such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of this investment
and to protect my own interests in connection therewith.  I have the financial
ability and resources to bear the economic risks of this investment.

     (e)  I understand that the Securities have not been registered under the
Securities Act in reliance upon a specific exemption therefrom, which exemption
depends, upon other things, the bona fide nature of my investment intent as
expressed herein and my intent to hold indefinitely the Securities unless
subsequently registered under the Securities Act or unless an exemption from
such registration is otherwise available.

     (f)  I understand that ADAC is obligated to use its best efforts to cause
these Securities to be registered pursuant to the terms of the Agreement.  I
acknowledge that because the registration process involves review and approval
by the Securities and Exchange Commission, no assurances can be given that such
efforts will succeed in registering these Securities in a timely manner or ever.
In addition, I understand that the certificate evidencing the Securities will be
imprinted with a legend which prohibits the transfer of the Securities unless
they are registered or such registration is not required in the opinion of
counsel for ADAC.

     (g)  I am aware of the provisions of Rule 144, promulgated under the
Securities Act, which in substance, permits limited public resale of "restricted
securities" acquired, directly or indirectly, from the issuer thereof (or from
an affiliate of such issuer), in a non-public offering subject to the
satisfaction of certain conditions, including, among other things: the
availability of certain public information about ADAC; the resale occurring not
less than two years after the party has purchased and paid for the securities to
be sold (absent registration); the sale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934) and
the amount of securities being sold during any three-month period not exceeding
the specified limitations stated therein.

     (h)  I further understand that in the event all of the requirements of Rule
144 are not satisfied, registration under the Securities Act, compliance with
Regulation A or some other registration exemption will be required before I may
resell the Securities; and that, notwithstanding the fact that Rule 144 is not
exclusive, the staff of the SEC has expressed its opinion that

                                       2
<PAGE>
 
persons proposing to sell private placement securities other than in a
registered offering and otherwise than pursuant to Rule 144 will have a
substantial burden of proof in establishing that an exemption from Registration
is available for such offers or sales and that such persons and their respective
brokers who participate in such transaction do so at their own risk.

================================================================================


     In connection with the merger of J.D. Technical Service, Inc. ("J.D.
Technical") and ADAC Acquisition, Inc. ("Acquisition") pursuant to that certain
Agreement and Plan of Reorganization (the "Agreement"), I understand that I will
receive shares of Common Stock (the "Securities") of ADAC Laboratories, a
California corporation ("ADAC"), and, as a condition to receiving such
Securities, the undersigned hereby represents to Acquisition and ADAC the
following:

     (a)  I have received copies of ADAC's Annual Report on Form 10-K for the
fiscal year ended October 2, 1994, and Quarterly Reports on Form 10-Q for each
fiscal quarter of the 1995 fiscal year.

     (b)  I understand and acknowledge that the initial issuance of the
Securities pursuant to the Agreement will not be registered under the Securities
Act of 1933, as amended (the "Securities Act"), on the grounds that the
issuances of these Securities are exempt from registration pursuant to Section
3(b) or Section 4(2) of the Securities Act or Regulation D promulgated
thereunder, and that ADAC's reliance upon such exemption is predicated upon my
representations contained herein.

     (c)  I am aware of ADAC's business affairs and financial condition and I
have acquired sufficient information about ADAC to reach an informed and
knowledgeable decision.  I have been given an opportunity to ask questions of
management of ADAC concerning the the terms and conditions of the merger, the
Agreement, the Securities and the business and financial condition of ADAC.
<PAGE>
 
     (d)  I am acquiring these Securities for my own account (or a trust account
if the undersigned is a trustee) for investment purposes only and not with a
view to, or for the resale in connection with, any "distribution" thereof in
violation of the Securities Act of 1933, as amended (the "Securities Act").  I
am able to fend for myself in connection with the purchase of the above
Securities and I have such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of this investment
and to protect my own interests in connection therewith.  I have the financial
ability and resources to bear the economic risks of this investment.

     (e)  I understand that the Securities have not been registered under the
Securities Act in reliance upon a specific exemption therefrom, which exemption
depends, upon other things, the bona fide nature of my investment intent as
expressed herein and my intent to hold indefinitely the Securities unless
subsequently registered under the Securities Act or unless an exemption from
such registration is otherwise available.

     (f)  I understand that ADAC is obligated to use its best efforts to cause
these Securities to be registered pursuant to the terms of the Agreement.  I
acknowledge that because the registration process involves review and approval
by the Securities and Exchange Commission, no assurances can be given that such
efforts will succeed in registering these Securities in a timely manner or ever.
In addition, I understand that the certificate evidencing the Securities will be
imprinted with a legend which prohibits the transfer of the Securities unless
they are registered or such registration is not required in the opinion of
counsel for ADAC.

     (g)  I am aware of the provisions of Rule 144, promulgated under the
Securities Act, which in substance, permits limited public resale of "restricted
securities" acquired, directly or indirectly, from the issuer thereof (or from
an affiliate of such issuer), in a non-public offering subject to the
satisfaction of certain conditions, including, among other things: the
availability of certain public information about ADAC; the resale occurring not
less than two years after the party has purchased and paid for the securities to
be sold (absent registration); the sale being made through a broker in an
unsolicited "broker's transaction" or in transactions directly with a market
maker (as said term is defined under the Securities Exchange Act of 1934) and
the amount of securities being sold during any three-month period not exceeding
the specified limitations stated therein.

     (h)  I further understand that in the event all of the requirements of Rule
144 are not satisfied, registration under the Securities Act, compliance with
Regulation A or some other registration exemption will be required before I may
resell the Securities; and that, notwithstanding the fact that Rule 144 is not
exclusive, the staff of the SEC has expressed its opinion that

                                       2
<PAGE>
 
persons proposing to sell private placement securities other than in a
registered offering and otherwise than pursuant to Rule 144 will have a
substantial burden of proof in establishing that an exemption from Registration
is available for such offers or sales and that such persons and their respective
brokers who participate in such transaction do so at their own risk.

                                             J.D. TECHNICAL SHAREHOLDER:

Securities Act of 1933;
         (ii)  To reflect in the prospectus any facts or events arising after
the effective date of the registration statement (or the most recent post-
effective amendment thereof) which, individually or in the aggregate, 
represents a fundamental change in the information set forth in the 
registration statement;
         (iii) To include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the registration statement;
     Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
the registration statement is on Form S-3 or Form S-8 and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed by the registrant pursuant to section 13 or
section 15(d) of the Securities Exchange Act of 1934 that are incorporated by
reference in the registration statement.
     
     (2)  That, for the purpose of determining any liability under the 
Securities Act of 1933, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the 
initial bona fide offering thereof.

     (3)  To remove from registration by means of a post-effective amendment any
of the securities being registered which remain unsold at the termination of the
offering.

(b)  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the 
Securities Exchange Act of 1934 (and, where applicable, each filing of an 
employee benefit plan's annual report pursuant to section 15(d) of the 
Securities Exchange Act of 1934) that is incorporated by reference in the 
registration statement shall be deemed to be a new registration statement 
relating to the securities offered therein, and the offering of such 
securities at that time shall be deemed to be the initial bona fide offering 
thereof.

(f)  Employee plans of Form S-8.
     (1)  The undersigned registrant hereby undertakes to deliver or cause to be
delivered with the prospectus to each employee to whom the prospectus is sent or
given a copy of the registrant's annual report to stockholders for its last
fiscal year, unless such employee otherwise has received a copy of such report,
in which case the registrant shall state in the prospectus that it will promptly
furnish, without charge, a copy of such report on written request of the
employee.  If the last fiscal year of the registrant has ended within 120 days
prior to the use of the prospectus, the annual report of the registrant for the
preceding fiscal year may be so delivered, but within such 120 day period the
annual report for the last fiscal year will be furnished to each such employee.

     (2)  The undersigned registrant hereby undertakes to transmit or cause to
be transmitted to all employees participating in the plan who do not otherwise
receive such material as stockholders of the registrant, at the time and in the
manner such material is sent to its stockholders, copies of all reports, proxy
statements and other communications distributed to its stockholders generally.

     (3)  Where interests in a plan are registered herewith, the undersigned
registrant and plan hereby undertake to transmit or cause to be transmitted
promptly, without charge, to any participant in the plan who makes a written
request, a copy of the then latest annual report of the plan filed pursuant to
section 15(d) of the Securities Exchange Act of 1934 (Form 11-K).  If such
report is filed separately on Form 11-K, such form shall be delivered upon
written request.  If such report is filed separately on Form 11-K, such form
shall be delivered upon written request.  If such report is filed as a part of
the registrant's annual report on Form 10-K, that entire report (excluding
exhibits) shall be delivered upon written request.  If such report is filed as a
part of the registrant's annual report to stockholders delivered pursuant to
paragraph (1) or (2) of this undertaking, additional delivery shall not be
required.

(i)  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is, 
therefore, unenforceable.  In the event that a claim for indemnification 
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by 
such director, officer or controlling person in connection with the securities
being registered, the registrant will, unless in the opinion of its counsel 
the matter has been settled by controlling precedent, submit to a court of 
appropriate jurisdiction the question whether such indemnification by it is 
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
