                             DESCRIPTION OF BUSINESS

OVERVIEW

         Mobile P.E.T. Systems, Inc. is a medical service provider operating
mobile Positron Emission Tomography ("PET") imaging systems in selected
marketplaces in the United States and Europe. PET imaging systems produce
images of the body that represent the metabolic characteristics of tissues
rather than anatomical information, providing for the earliest detection of
many abnormalities that are undetected with conventional x-ray, Computerized
Axial Tomography ("CT"), or Magnetic Resonance Imaging ("MRI") imaging
systems. PET effectively detects many cancers, cardiac and neurological
disorders at their earliest stages which influences patients' treatment
options and eliminates redundant testing, hospitalization or non-beneficial
treatment procedures.

         We provide the PET imaging system housed in a mobile coach. We also
provide the technical personnel who operate the equipment and implement the
PET procedure under the direction of hospital physicians. Our contracted
services provide hospitals, which do not have high patient volumes to
purchase or support a dedicated PET system, access to this advanced
diagnostic imaging technology and the related patient benefits.

ABOUT OUR INDUSTRY

         The diagnostic imaging industry generates annual revenues in excess
of $50 billion in the United States, or approximately 5% to 6% of total
health care spending. There are at present approximately 84 PET systems in
the United States, including approximately 75 hospital-owned systems, 5
independent fixed site systems and 4 mobile units. By comparison, in 1998
there were approximately 4,000 MRI systems in the United States consisting of
approximately 2,400 hospital owned systems, 1,000 independent fixed site
systems and 600 mobile systems.

         Recent studies by the Institute for Clinical PET ("ICP") concluded
that PET is a cost-effective diagnostic imaging procedure for a number of
indications. In cost-effectiveness studies conducted by the ICP, the use of
PET in four indications for the United States Medicare and non-Medicare
populations demonstrated significant cost savings. The four retrospective
studies focused on lung cancer, breast cancer, colorectal cancer recurrence,
and myocardial viability. In the studies of these four indications in the
Medicare population, ICP estimated the total Medicare savings from the use of
PET diagnostic imaging procedures would approximate $1.6 billion per year. In
addition, ICP estimated the number of invasive and other diagnostic
procedures would be reduced by 189,162 procedures. Finally, ICP estimated the
number of annual PET studies required for the four indications in the
Medicare population would be 388,951. ICP's cost effectiveness studies for
the non-Medicare population concluded the total cost savings from the use of
PET diagnostic imaging would approximate $4.1 billion annually. In this
population, ICP estimates the number of invasive and other diagnostic
procedures would be reduced by 182,520 procedures annually. In addition, ICP
indicated that the number of annual PET studies required in this population
would approximate 401,616 tests. It should be noted that ICP's calculations
examined only the savings related to the cost of the procedures avoided, and
did not include additional savings realized by avoiding the complications of
procedures rendered unnecessary by knowledge of PET results.

THE PET PROCEDURE

         Commercial diagnostic PET imaging systems are comprised of high
speed computers, an examination table and a large imaging detector gantry,
which are used to acquire and produce detailed PET images of the human body's
metabolic functions. Performing an actual PET procedure scan involves first
introducing a radioisotope into the patient's blood stream. The patient is
then placed on an examination table which is electronically positioned into
the middle of an "open-air gantry" of the PET scanner.

         The PET imaging system detects signals emitted by the radioisotope
as it moves through the body. The radioisotope is attracted to any metabolic
activity. As an example, cancer cells (which are highly metabolic) are
easily detected by the PET imaging procedure. A high-speed computer
reconstructs the signals into three dimensional images that display normal or
abnormal metabolic function. The most commonly used radioisotope is
fluro-deoxyglucose (FDG),

                                       1
<PAGE>

a glucose based radioisotope. The radioisotope used in the PET procedure
dissipates within twenty-four hours and the patient may go home the same day.

THE ADVANTAGES OF PET

         PET offers fundamental advantages over other diagnostic imaging
techniques as it provides a direct measure of biochemistry and functional/
metabolic activity. In most cases, the precursors to all disease are
biochemical in nature and initially affect function, as opposed to structure.
PET, which has a unique ability to create a diagnostic image of early
metabolic changes, can significantly reduce the time to diagnosis, reduce
costs and improve patient outcomes for numerous indications for oncology,
cardiology and neurology.

         PET offers the following substantial advantages over current diagnostic
imaging procedures:

          --   replaces the need for multiple, costly medical testing with a
               single imaging procedure;
          --   displays a 3D image of all of the organ systems of the body with
               one examination;
          --   diagnoses and detects diseases, in most instances, before
               detection by other tests;
          --   monitors the path and progress of disease as well as how the body
               responds to treatment;
          --   reduces or eliminates ineffective or unnecessary surgical/
               medical treatments and hospitalization; and
          --   reduces redundant medical costs and avoids needless discomfort to
               the patient.

         As a result of the cost efficiency and clinical effectiveness of
PET, hospitals and other health care providers are facing pressures from
their patients to provide PET technology and related services. Increasingly,
such health care providers are utilizing third parties, like our company, to
provide technology-driven patient services.

         Approximately 7.4 million Americans have a history of cancer, and
1.3 million new U.S. cancer cases will be diagnosed in 1999. PET is currently
recognized as the only metabolic medical tool powerful enough to accurately
image and measure with a single pass the metabolic function of cancer. It can
also provide information to determine whether a primary cancer has
metastasized to other parts of the body. PET has demonstrated its usefulness
in cost-effective, whole-body metastatic surveys; avoiding biopsies for
low-grade tumors; non-invasive differentiation of tumors from radiation
necrosis; early change in course of ineffective chemotherapy; and avoiding
unnecessary diagnostic and therapeutic surgeries.

         In cardiology, a PET scan is one of the most accurate tests to
detect coronary artery disease. The PET images can display inadequate blood
flow to the heart during stress that is undetected by other non-invasive
cardiac tests. PET enables physicians to screen for coronary artery disease,
to assess flow rates and flow reserve, and to distinguish viable from
nonviable myocardium for bypass and transplant candidates. It is also fast
becoming an indispensable tool for cardiologists attempting to achieve
reversal of coronary artery disease through aggressive risk factor
modification such as the Ornish diet program, enabling both doctor and
patient to directly and non-invasively measure the progress of improvement in
coronary blood flow.

         In neurology, PET can assist in the early detection and diagnosis of
such brain disorders as Alzheimer's and Parkinson's diseases. PET scans can
detect a consistent diagnostic pattern for Alzheimer's disease where certain
regions of the brain may show decreased metabolism early in the disease. This
pattern often can be recognized several years before a physician is able to
make the diagnosis clinically. In addition, PET scans can differentiate
Alzheimer's from other confounding types of dementia or depression. In a
similar fashion, PET scans can detect Parkinson's disease. A labeled acid is
used with PET to determine if the brain is deficient in dopamine synthesis.
If it is determined there is no deficiency and the patient is not suffering
from Parkinson's disease, then the course of tremor evaluation and treatment
will be different.

         According to the ICP and the UCLA School of Medicine, PET diagnostic
imaging offers medical specialists a metabolic and clinical process to
pinpoint soft-tissue disorders. MRIs provide anatomical images of the body
that are not as effective as PET's 10-year history of early diagnosis of a
growing number of cancers, heart and brain disorders.


                                       2
<PAGE>

         CT scanning is also less effective than PET scans as a tool for
early detection and diagnosis. PET imaging has displayed the following
detection rates compared to CT scanning and mammography:

          --   an 81% detection rate for lung cancer, compared to a 52%
               detection rate with CT;
          --   a 95% detection rate for colon cancer, compared to a 68%
               detection rate with CT; and
          --   an 85% detection rate for breast cancer, compared to a 67%
               detection rate for mammography.

         Considering only the 131,600 new incidences of colon cancer
diagnosed in 1998, PET imaging services would have detected, based on the 95%
detection rate, 125,020 incidences as compared to only 89,488 incidences from
CT scanning. This represents a 40% higher rate of detection.

OUR SERVICES

         We provide convenient cost effective PET imaging services for
hospitals, medical centers and other health care providers that are unable to
financially justify the acquisition of this important technology.

         All of our PET imaging systems are housed in mobile coaches or
trailers. The coach design combines convenience, patient comfort and safety,
and includes a powered patient lift, stairway, stabilizing system for
leveling, and transportation alarm to warn of equipment not properly stowed
for transport. The interior space of the coach is divided into three
sections: a patient imaging room, a technology control room, and the PET
imaging equipment section.

         We provide hospitals with PET diagnostic imaging service time to
easily accommodate their patients on a daily basis. We anticipate physician
referrals will increase to a minimum of approximately nine exams per day of
service.

         We offer a complete, comprehensive "Total Solutions" approach to our
clients which includes:

          --   Medical Advisory Board to stage PET seminars that inform
               referring physicians on the benefits of PET.
          --   Physician training programs and expert overread services that
               assist the hospitals' staff physicians to become qualified PET
               exam interpreters.
          --   Electronic data transmission and archiving of all PET exams by
               use of our Internet site and software package.
          --   Licensure assistance by our physicists.
          --   PET Site Planning Guide and support to accommodate mobile PET
               trailers to each of our clients' locations.
          --   PET Strategic Marketing Plan complete with regional specialists
               to evaluate and inform referring physicians.
          --   Convenient access to radiotracers at negotiated discount rates
               through our master buying agreements.

         We currently have eight state-of-the art ECAT-Registered Trademark-
EXACT-TM- PET systems on order from CTI/Siemens Medical Systems and we are
ordering ten Registered Trademark-ADVANCE-TM PET Imaging Systems from General
Electric Medical Systems. We have received three mobile Siemens PET systems
to date, one of which is in operation in Southern California. We expect the
balance of the Siemens PET systems to be in operation by year end 1999 with
the first European system in operation by January 2000. We expect to receive
the first GE Registered Trademark-ADVANCE-TM PET Imaging Systems commencing
in the second quarter of 2000. The cost for a fully commissioned mobile PET
imaging system can range from $1.6 to $2.0 million.

         The Siemens ECAT-Registered Trademark- EXACT-TM- scanner is a
whole-body system that provides 2D and 3D volume measurements of metabolic and
physiologic processes. The system consists of the ECAT-Registered Trademark-
EXACT-TM- scanner, an integrated workstation, the 3D Advanced Computational
System, and patient couch.

OUR OPERATIONS

         CUSTOMER BASE. We believe that many hospitals and other health care
providers will seek access to PET imaging services to remain competitive in
the health care marketplace.

         Regulatory and licensing requirements in many states may also limit
general access to PET imaging services. In addition, many health care
providers lack sufficient patient volumes or financial resources to justify
the purchase of a dedicated in-house PET system. As a result, providers will
consider contracting for mobile services to gain access to PET technology,
build patient flows and provide comprehensive PET services to their
communities.

         Many health care providers, regardless of whether their patient flow
levels and financial resources justify the purchase of a PET system, may
prefer to contract with us to (i) obtain the use of a PET system without
significant capital investment or financial risk; (ii) retain the ability to
switch system types and avoid technological risk; (iii) eliminate the need to
recruit, train and manage qualified technologists; or (iv) provide expanded
imaging services when patient demand exceeds their in-house capability.

         SERVICE CONTRACTS. We structure our service contracts with hospitals
and health care providers for a term of five years, with fees charged on a
fee-per-patient basis and minimum patient volumes. To date, we have entered
into service agreements with the following hospitals and health care
providers: (i) Pomona Valley Hospital Medical Center; (ii) Saint John's
Health Center; (iii) South Coast Nuclear Medicine Group; and (iv) Spectrum
Medical Management.

         REIMBURSEMENT. Mobile diagnostic imaging service providers are
generally not reimbursed directly by health care payors such as Medicare,
Medicaid, insurance companies or managed care companies. Instead, mobile
diagnostic imaging service companies contract directly with and are paid by
the hospital, which then bills the health care payors. All of our revenues
will be paid directly by the hospital. As a result, we should realize a
higher level of accounts receivable turnover and a lower allowance for
uncollected debt.

         Billing and reimbursement for diagnostic imaging services is divided
into a technical component and a professional component. Our business revenue
is based on providing the technical component, which includes the cost of the
equipment, labor and materials needed to perform the procedure by our company
and a hospital. The professional component is the cost of interpreting the
image by the nuclear medicine physician or radiologist.

         We contract with a hospital to receive a negotiated rate for the
technical component of the imaging service. This wholesale rate pays us for
providing the technical component of the service and allows the hospital to
mark up the service to the healthcare payor. This markup reimburses the
hospital for its services rendered to the patient and the associated
physician costs. At the current time, the average insurance reimbursement to
a hospital for a particular PET procedure is $1,900 to $3,100.

         Insurance companies currently reimburse approximately 70% of PET
procedures. In January 1998, the Health Care Financing Administration (HCFA)
approved Medicare reimbursement for the diagnostic evaluation of solitary
pulmonary nodules and for staging non-small cell lung cancer. In March 1999,
the HCFA announced approval to reimburse PET scans in the diagnosis and
management of certain cancers in Medicare beneficiaries. The March 1999
announcement approves the reimbursement for the detection and localization of
recurrent colorectal cancer with rising carcinoembryonic antigen known as
CEA; staging and characterization of both Hodgkins and non-Hodgkins lymphoma
in place of a gallium scan or lymphangiogram; and identification of
metastases in melanoma recurrence in place of gallium studies.

         The implication of the foregoing HCFA approvals is an indication
that a promising technology has at last become commercially feasible. For
nearly 20 years PET imaging has shown tremendous promise in the investigation
of pharmacologic agents and the management of cancer patients, cardiac
patients and certain neurologic indications, but has not been reimbursable.
This has prevented the dissemination of this technology to community
hospitals and restricted its use to major medical centers. It appears that
small to medium hospitals can now avail themselves of a cutting edge
technology which promises to become a standard of health care.

OUR COMPETITIVE STRATEGY

         Our management team has developed and will implement a business
strategy designed to maximize return on invested capital and increase
revenues and cash flow. Our goal is to achieve a leadership position in our
industry as well as pursue significant growth opportunities based on the
following competitive strategies:

         BECOME THE LARGEST PROVIDER OF MOBILE PET SERVICES. By the end of
1999, we plan to be operating mobile PET systems in four states - California,
Florida, Texas and New York. As we grow, we believe we will benefit from (i)
significant equipment purchasing savings; (ii) attractive service and
maintenance contracts from our primary equipment suppliers; (iii) strong name
recognition and a reputation for quality service; (iv) substantial financial
flexibility and access to lower-cost capital; and (v) the ability to
efficiently deploy systems in a manner which maximizes fleet utilization
while satisfying our customer requirements.

         SUPERIOR CUSTOMER SERVICE AND STRONG CUSTOMER RELATIONSHIPS. We will
position ourselves as a service company rather than solely as a supplier of
equipment and will compete on the basis of value-added services in addition
to price. We will differentiate ourselves from potential competitors by
aggressively marketing our services to referring physicians, nuclear medicine
specialists, radiologists and hospital administrators by offering advance PET
imaging systems, trained technologists, as well as marketing and education
programs to accommodate the growing needs of our customers.

         SECURE EXCLUSIVE, LONG-TERM CONTRACTS WITH KEY HOSPITALS IN
ATTRACTIVE MARKETS. We will generate all of our revenues from exclusive,
long-term contracts with hospitals and other health care providers, with the
price for our services determined on a fee for service basis. Our marketing
focus is currently directed at four key market segments in the U.S. They
include California, New York, Texas and Florida. We have initially targeted
40 hospitals in each market which we believe require access to PET services.
These targeted hospitals need to remain competitive in their respective
health care markets or may lack sufficient patient volumes to justify the
purchase of a dedicated PET system. We have pursued securing long-term
contracts with several high profile university hospitals, which offer the
potential of establishing market presence and name recognition for our
company. We have also developed a "Total Solutions" strategy which will
utilize our senior executives and our Medical Advisory Board members to help
our customers during the start-up phases at their facilities. Our "Total
Solutions" approach includes physician education and a focused marketing
effort to build a physician referral base. Our "Total Solutions" approach
also enables us to provide consultation in the areas of billing and third
party contracts.

         SUBSTANTIAL OPERATING LEVERAGE. Because of the significant amount of
fixed costs associated with operating a mobile PET system, we can benefit
from operating leverage, with increased utilization rates resulting in
significant increases in operating earnings and margins.

         FAVORABLE PAYMENT TERMS. A majority of our billings will be direct
to hospitals. The hospitals, in turn, generally will pay us prior to
collecting from patients and third party payors. Accordingly, our exposure to
uncollectable patient receivables will be minimized. In addition, we estimate
that the average number of days sales outstanding ("DSO") of receivables will
be approximately 60 to 90 days which would be more favorable than the DSO of
many health care companies.

         EXPERIENCED MANAGEMENT TEAM. Our senior management team has
considerable industry experience. Our senior and operating managers have
successfully developed and implemented marketing, operating and financial
strategies with previous health care companies.

         INCREASE SCAN VOLUMES. We believe that the demand for PET procedures
will continue to grow as new applications are developed and PET continues to
gain increased acceptance resulting in replacing and/or supplementing other
imaging technologies. We have an opportunity to achieve a growing level of
patient procedures by both adding new customers and increasing the number of
patient procedures performed for these customers.


                                       5
<PAGE>


         MAXIMIZE RETURN ON INVESTED CAPITAL. We will actively manage the
utilization of our PET systems to maximize our return on capital (i.e., the
amount of cash flow generated by each system relative to the carrying value
of such system). We estimate that, on average, a system can be utilized for
approximately eight years in a high demand market when properly maintained
and upgraded, after which time the system can either be utilized in a market
with less demand or traded in for a new system.

         IDENTIFY ATTRACTIVE STRATEGIC ACQUISITIONS. Although our
management's initial operational focus will be directed to the significant
internal growth opportunities we have identified and targeted, we will
attempt to identify attractive strategic acquisition opportunities that may
arise as well as our ability to (i) access additional and lower cost
financial resources; (ii) realize significant synergies, operating expense
reduction and overhead cost savings; and (iii) expand into new geographic
markets.

CUSTOMER SUPPORT

         As part of our professional services, we provide several levels of
support to a hospital or health care provider, including (i) developing
commercial and clinical marketing materials; (ii) sponsoring clinical
lectures; and (iii) offering educational over-read services. In addition,
consulting services for billing, collections, and third-party contracts are
available on request. We believe that these services play a key role in our
ability to sign up routes over competitors, retain accounts and build patient
procedures.

SALES AND MARKETING

         Our sales force consists of five regional marketing representatives.
These representatives identify, qualify and contact candidates about our
services. Each sales representative has overall management and revenue
responsibility for a specific region of the country.

         Direct marketing to referring physicians plays a primary role in our
ability to increase patient procedures. Our marketing representatives focus
on developing increased scan volumes by introducing our PET services to
referring physicians and keeping such physicians apprised of our PET service
capabilities. In addition, certain of our executive officers spend a portion
of their time marketing our services. We have also assembled a Medical
Advisory Board comprised of leading physicians who will assist in educational
programs directed to the medical community which will enhance our ability to
attract and retain customers.

         Our initial target market includes hospitals located in metropolitan
areas that have an on-site oncology department or have affiliated oncology
service relationships. We believe there are approximately 2,000 hospitals in
the U.S. that meet this criteria. Our initial sales and marketing focus has
been directed at the four major markets of California, New York, Texas and
Florida. Our representatives have initially targeted approximately 40
hospitals in each market. We believe that approximately 15 of these hospitals
in each market are at a mature negotiating stage for the potential signing of
contracts.

RISKS RELATED TO OUR BUSINESS

THERE ARE RISKS ASSOCIATED WITH FORWARD-LOOKING STATEMENTS MADE BY US AND ACTUAL
RESULTS MAY DIFFER.

         Some of the information in this registration statement contains
forward-looking statements that involve substantial risks and uncertainties.
You can identify these statements by forward-looking words such as "may,"
"will," "expect," "anticipate," "believe," "estimate," and "continue" or
similar words. You should read statements that contain these words carefully
because they:

          -    discuss our future expectations;
          -    contain projections of our future results of operations or of our
               financial condition; and
          -    state other "forward-looking" information.


                                       6
<PAGE>

         We believe it is important to communicate our expectations. However,
there may be events in the future that we are not able to accurately predict
or over which we have no control. The risk factors listed in this section, as
well as any cautionary language in this registration statement, provide
examples of risks, uncertainties and events that may cause our actual results
to differ materially from the expectations we describe in our forward-looking
statements. You should be aware that the occurrence of the events described
in these risk factors and elsewhere in this registration statement could have
an adverse effect on our business, results of operations and financial
condition.

WE HAVE INCURRED NET LOSSES SINCE INCEPTION AND EXPECT FUTURE LOSSES.

         Since inception, we have incurred significant losses, and as of June
30, 1999, had incurred cumulative net losses of $619,763. As of June 30,
1999, we had an accumulated deficit of approximately $1,446,599. We expect to
continue to incur net losses until sales generate sufficient revenues to fund
our continuing operations. We may fail to achieve significant revenues from
sales or achieve or sustain profitability.

IF WE DO NOT BECOME PROFITABLE WE MAY NOT BE ABLE TO SUSTAIN OUR OPERATIONS.

         Our ability to achieve profitability in the future will depend in
part on our ability to continue to successfully market and sell PET services
on a wide scale. In turn, our future sales and profitability depend in part
on our ability to demonstrate to hospitals the potential cost and performance
advantages of the PET system over traditional diagnostic imaging systems. To
date, commercial sales of PET services have been limited. We do not know if
PET services or mobile PET service can be successfully commercialized on a
broad basis.

OUR PRODUCTS MAY NOT BE ACCEPTED BY THE MEDICAL COMMUNITY OR BY PATIENTS.

         The acceptance of PET technology may be adversely affected by its
high cost, concerns by patients and physicians relating to its safety and
efficacy, and the substantial market acceptance of other diagnostic tools
such as MRIs and CT scans. We have a limited sales force and will need to
hire additional sales, technologists, and marketing personnel to increase the
general acceptance of PET services. Of all the factors impacting our
profitability, the failure of PET services to achieve broad market acceptance
would have the greatest negative impact on our business, financial condition
and results of operations and our profitability.

WE ARE DEPENDENT ON A SMALL NUMBER OF SUPPLIERS THE LOSS OF WHICH COULD
ADVERSELY AFFECT OUR BUSINESS.

         We purchase the PET system from a limited group of qualified
suppliers. Siemens has approximately 75% of the market share for PET systems
worldwide. While we believe that alternative suppliers could be found for the
PET system, we cannot assure you that any supplier could be replaced in a
timely manner. Any interruption in the supply and/or delivery of the PET
system could materially harm our ability to conduct our business, our
financial condition and results of operations.

WE MAY BE UNABLE TO PROVIDE ADEQUATE SUPPORT TO OUR CUSTOMERS.

         We have limited experience with widespread deployment of our
products and services to a diverse customer base, and there can be no
assurance that we will have adequate personnel to provide the level of
support that our customers may require during initial product deployment or
on an ongoing basis. An inability to provide sufficient support to our
customers could have an adverse impact on our reputation and relationship
with our customers, prevent us from gaining new customers, and adversely
affect our business, financial condition or results of operations.

OUR FOREIGN SALES ARE SUBJECT TO RISKS.

         An increasing portion of our sales may be made in foreign markets.
The primary risks to which we are exposed due to our foreign sales are the
difficulty and expense of maintaining foreign sales distribution channels,
political and economic instability in foreign markets and governmental quotas
and other regulations.


                                       7
<PAGE>

         The regulation of medical devices worldwide also continues to develop,
and it is possible that new laws or regulations could be enacted which would
have an adverse effect on our business. In addition, we may experience
additional difficulties in providing prompt and cost effective service of PET
scans in foreign countries. We do not carry insurance against these risks. The
occurrence of any one or more of these events may individually or in the
aggregate have an adverse effect upon our business, financial condition and
results of operations.

THE PET SYSTEM MAY BECOME TECHNOLOGICALLY OBSOLETE AND OUR BUSINESS COULD BE
HARMED.

         The markets in which our PET system competes are subject to rapid
technological change as well as the potential development of alternative
diagnostic imaging techniques or products. These changes could render the PET
system uncompetitive or obsolete. Although we believe that the PET system can be
upgraded to maintain its state-of-the-art character, the development of new
technologies or refinements of existing ones might make PET systems
technologically or economically obsolete, or cause a reduction in the value of,
or reduce the need for, PET systems. Although we are not aware of any
substantial technological change, should such change occur, there can be no
assurance that we will be able to acquire the new or improved systems which may
be required to service our customers.

         We are also subject to the risk that customers will cease using our PET
services upon expiration of contracts and purchase or lease their own PET
systems.

OUR BUSINESS IS SUBJECT TO GOVERNMENTAL REGULATION.

         We are required to adhere to a wide variety of other regulations
governing the operation of our business. Noncompliance with state, local,
federal or foreign requirements can result in serious penalties that could harm
our business. Although we believe that our operations comply with applicable
regulations, there can be no assurance that subsequent adoption of laws or
interpretations of existing laws will not regulate, restrict or otherwise
adversely affect our business.

         Federal regulations commonly known as the "Stark Laws" impose civil
penalties and exclusion from participation in the Medicare program of
reimbursement for referrals for "designated health services" by physicians to
certain entities with which they have a financial relationship (if those
referrals do not fall within an exception to the prohibition). "Designated
health services" include, among other things, PET services. While implementing
regulations have been issued relating to referrals for clinical laboratory
services, no implementing regulations have been issued regarding the other
designated health services, including PET services. Further, under the proposed
implementing regulations interpreting the Stark Laws, it is likely that these
proposed rules will apply to mobile PET scanners, thereby restricting certain
physician referrals for such services by an investor-physician. In addition,
several states (including the State of California) in which we operate or plan
to operate have enacted or are considering legislation that restricts "physician
self-referral" arrangements in a manner similar to the Stark Laws and requires
physicians to disclose any financial interest they may have with a health care
provider to their patients to whom they recommend that provider. Possible
sanctions for violating these provisions include loss of licensure and civil and
criminal sanctions. Such state laws vary from state to state and seldom have
been interpreted by the courts or regulatory agencies. Nonetheless, strict
enforcement of these requirements is likely.

         There are also numerous federal and state laws which govern financial
and other arrangements between health care providers. These include the federal
Medicare and Medicaid anti-kickback statutes which prohibit bribes, kickbacks,
rebates and any other direct or indirect remuneration in return for or to induce
the referral of an individual to a person for the furnishing, directing or
arranging of services, items or equipment for which payment may be made in whole
or in part under Medicare, Medicaid or other federal health care programs.
Violation of the anti-kickback statute may result in criminal penalties and
exclusion from the medicare and other federal health care programs. Many states
have enacted similar statutes which are not necessarily limited to items and
services paid for under Medicare or a federally funded health care program. We
believe we can market our services to health professionals and provide such
services without violating or encouraging the violation of these and related
laws dealing with the provision of health care services. However, our failure or
our customers' failure to comply with these laws and/or the Stark Laws could
result in an adverse effect on our business.

                                       8

THE LOSS OF ANY OF OUR OTHER KEY PROFESSIONALS COULD ADVERSELY AFFECT OUR
BUSINESS, INCLUDING OUR ABILITY TO DEVELOP AND MARKET OUR PRODUCTS.

         We depend to a considerable degree on a limited number of key
personnel, who are listed in the "Management" section of this registration
statement. During our limited operating history, many key responsibilities have
been assigned to a relatively small number of individuals. The loss of the
services of key members of our management could harm our business. Our success
will also depend, among other factors, on the successful recruitment and
retention of qualified technical and other personnel.

IF WE FAIL TO COMPETE SUCCESSFULLY, OUR REVENUES AND OPERATING RESULTS WILL BE
ADVERSELY AFFECTED.

         We are, and will continue to be, subject to intense competition in our
targeted markets, principally from businesses providing other traditional
diagnostic imaging techniques, including existing and developing technologies,
and competitive products. Many of our competitors have substantially greater
financial, marketing and manufacturing resources and experience than us.
Furthermore, we expect that other companies will enter the mobile and stationary
PET market, particularly as PET systems gain increasing market acceptance.
Significant competitive factors which will affect future sales in the
marketplace include regulatory approvals, performance, pricing and general
market acceptance.

         The diagnostic imaging market is also highly competitive. There are
many companies engaged in this market, some with significantly greater resources
than ours. Our competitors may be able to develop technologies, procedures or
products that are more effective or economical than ours, or that would render
the PET system obsolete or noncompetitive.

         We compete with free-standing imaging centers and health care providers
that have their own diagnostic imaging systems and with equipment manufacturers
that sell or lease imaging systems to health care providers for full-time
installation. Some of our customers may be capable of providing the same
services to their patients directly.

A SUCCESSFUL LIABILITY CLAIM ASSERTED AGAINST US DUE TO A DEFECT IN THE PET
SYSTEM IN EXCESS OF OUR INSURANCE COVERAGE WOULD HARM OUR BUSINESS.

         The provision of mobile PET shared services involves the inherent risk
of professional and product liability claims against us. We currently maintain
commercial general liability insurance coverage in the amount of $2 million per
incident and medical professional liability insurance in the amount of $2
million per incident, but this insurance is expensive, subject to various
coverage exclusions and may not be obtainable in the future on terms acceptable
to us. We do not know whether claims against us arising from our use of the PET
system will be successfully defended or that our insurance will be sufficient to
cover liabilities arising from these claims. A successful claim against us in
excess of our insurance coverage could materially harm our business.

THERE IS UNCERTAINTY RELATING TO THIRD PARTY REIMBURSEMENT WHICH IS CRITICAL TO
MARKET ACCEPTANCE OF OUR PRODUCTS.

         PET services are generally purchased by hospitals which then bill
various third party payors, such as government programs and private insurance
plans, for the procedures conducted using the PET system. Third-party payors
carefully review and are increasingly challenging the prices charged for
medical products and services, and scrutinizing whether to cover new products
and evaluating the level of reimbursement for covered products. While we
believe that the hospitals using the PET system have generally been
reimbursed, payors may deny coverage and reimbursement for the PET system if
they determine that the device was not reasonable and necessary for the
purpose for which it was used, was investigational or not cost-effective. As
a result, we cannot assure you that reimbursement from third party payors for
use of the PET system will be available or if available, that reimbursement
will not be limited. If third party reimbursement of these procedures is not
available, it will be more difficult for us to offer our services on a
profitable basis. Moreover, we are unable to predict what legislation or
regulation, if any, relating to the health care industry or third-party
coverage and reimbursement may be enacted in the future, or what effect such
legislation or regulation may have on us.

                                       9

WE ARE EXPOSED TO RISKS RELATING TO HEALTH CARE REFORM.

         Several states and the United States government are investigating a
variety of alternatives to reform the health care delivery system and further
reduce and control health care spending. These reform efforts include proposals
to limit spending on health care items and services, limit coverage for new
technology and limit or control the price health care providers and drug and
device manufacturers may charge for their services and products. If adopted and
implemented, such reforms could have an adverse effect on our business,
financial condition and results of operations.

IF WE EXPERIENCE PROBLEMS WITH YEAR 2000 COMPLIANCE OUR OPERATIONS MAY BE
DISRUPTED.

         Many existing computer programs use only two digits to identify the
year in the date field. These programs were designed and developed without
considering the impact of the upcoming change in the century. As a result, any
computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the Year 2000. This could result in system
failure or miscalculations, causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices or
engage in similar normal business activities.

         If our key suppliers or customers experience Year 2000 compliance
issues, then our business could be harmed. If there is a failure in Year 2000
compliance by us or one of our suppliers or customers, we could suffer major
disruptions in our ability to schedule PET services, obtain PET systems, or
receive payment for our sales. There can be no assurance that our business will
not be negatively affected by Year 2000 problems experienced by our suppliers or
customers.

IF WE ARE UNABLE TO OBTAIN ADDITIONAL FUNDING OUR BUSINESS OPERATIONS WILL BE
HARMED.

         We believe that our available short-term assets and investment income
will be sufficient to meet our operating expenses and capital expenditures
through the current fiscal year. We do not know if additional financing will be
available when needed, or if it is available, if it will be available on
acceptable terms. Insufficient funds may prevent us from implementing our
business strategy or may require us to delay, scale back or eliminate certain
contracts for the provision of PET services.

OUR EMPLOYEES

         We currently have 12 full-time employees and 1 part-time employee. Our
employees are non-union and none are represented by an organized labor union. We
believe our relationship with our employees is very good and we have never
experienced an employee related work stoppage. We will need to hire and retain
highly-qualified experienced technical and select management personnel in order
to execute our business plan and maintain technical advantages over competitors
in the marketplace. No assurances can be given that we will be able to locate
and hire such personnel, or that, if hired, we will continue to be able to pay
the higher salaries necessary to retain such skilled employees.

OUR CORPORATE HISTORY

         Mobile P.E.T. Systems, Inc. was originally formed as a Nevada
corporation in December 1998 ("Mobile Nevada"). Soon after its formation, Mobile
Nevada's founders (who are now our majority shareholders) decided that their
company's business plan would be best accomplished if Mobile Nevada became a
publicly traded corporation. The founders concluded that the easiest and most
efficient way to achieve their goal was to locate an existing publicly traded
corporation which would acquire Mobile Nevada. That corporation was our
predecessor -- Colony International Corporation ("Colony Delaware").

         Colony Delaware's predecessor, American Coin & Stamp Ventures, Inc.
("American"), was formed as a Delaware corporation in August 1985. American
supplied various editorial and advertising services to publishers. In 1986,
American made an initial public offering of its stock. Its shares were
thereafter publicly traded under the trading symbol "ACSV." In January 1997,
American sold its business to its existing management and conducted a reverse
split of its stock on a 1:19.926 basis, leaving 491,311 shares of common stock
outstanding.


                                       10

<PAGE>

         American then acquired Colony International Incorporated, a
corporation formed in Nevada in April 1995 ("Colony Nevada"). Colony Nevada
was a development stage company which intended to manufacture and distribute
a technologically advanced solid waste management system. American acquired
Colony Nevada by exchanging newly issued shares of American common stock for
the shares of Colony Nevada common stock then outstanding. Once the
acquisition was completed, American officially changed its corporate name to
Colony International Incorporated ("Colony Delaware") and its trading symbol
to "CIIA." After the acquisition, American's former shareholders held
approximately 5% of the shares of Colony Delaware, and Colony Nevada's former
shareholders (and certain consultants who assisted in the acquisition) held
approximately 95% of the shares of Colony Delaware.

         In December 1998, Colony Delaware transferred its business to Brian
Hauff, its sole officer and director. Colony Delaware then reverse split its
shares on a 1:50 basis. Colony Delaware then acquired Mobile Nevada by
exchanging 7,000,000 newly issued shares of Colony Delaware common stock for
the 7,000,000 shares of Mobile Nevada common stock then outstanding. Once the
acquisition was completed, Colony Delaware changed its corporate name to
Mobile P.E.T. Systems, Inc. and its trading symbol to "MBPT," and officially
became the corporation we are now. After the acquisition, Colony Delaware's
former shareholders held approximately 37% of our shares, and Mobile Nevada's
former shareholders held 63% of our shares.

         We still own all of the shares of Colony Nevada and Mobile Nevada. We
intend to dissolve these two corporations.

ADDITIONAL INFORMATION

         We intend to provide an annual report to our security holders, and to
make quarterly reports available for inspection by our security holders. The
annual report will include audited financial statements.

         Upon completion of this offering, we will be subject to the
informational requirements of the Securities Exchange Act of 1934 (the "Exchange
Act") which will require us to file reports, proxy statements and other

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

         THE FOLLOWING DISCUSSION AND ANALYSIS OF OUR FINANCIAL CONDITION AND
RESULTS OF OPERATIONS SHOULD BE READ IN CONJUNCTION WITH THE FINANCIAL
STATEMENTS AND THE RELATED NOTES. THIS DISCUSSION CONTAINS FORWARD-LOOKING
STATEMENTS BASED UPON CURRENT EXPECTATIONS THAT INVOLVE RISKS AND UNCERTAINTIES,
SUCH AS OUR PLANS, OBJECTIVES, EXPECTATIONS AND INTENTIONS. OUR ACTUAL RESULTS
AND THE TIMING OF CERTAIN EVENTS COULD DIFFER MATERIALLY FROM THOSE ANTICIPATED
IN THESE FORWARD-LOOKING STATEMENTS AS A RESULT OF CERTAIN FACTORS, INCLUDING
THOSE SET FORTH UNDER "RISK FACTORS," "BUSINESS" AND ELSEWHERE IN THIS
PROSPECTUS. SEE "FORWARD-LOOKING STATEMENTS."

OVERVIEW

         For the period from our inception through June 30, 1999, we had no
revenues and our operating activities related primarily to establishing the
management and operating infrastructure to provide PET systems and services to
hospitals and other health care providers on a mobile, shared user basis. Since
forming the Company, operating activities have been focused on establishing a
national sales force; creating and executing a sales and marketing strategy
directed


                                       11

<PAGE>

to key potential hospital and health care providers; securing a $10 million
lease financing package; establishing key equipment vendor relationships;
promoting our service brand strategy; and building a management and
operations infrastructure to effectively and efficiently manage future
operating growth opportunities.

         We plan to provide PET systems and services to hospitals and other
health care providers on a mobile, shared user basis. Our PET services will
include the provision of high technology imaging systems, technologists to
operate the imaging systems, the management of day-to-day operations and
educational and marketing support. Our services will enable leading as well
as small to mid-size hospitals to gain access to advanced diagnostic imaging
technology and related value-added services without making a substantial
investment in equipment and personnel.

         Our future revenues will principally be a function of the number of
mobile units in service, scan volumes and fees per scan. We will generate
substantially all of our revenues under exclusive five-year contracts with
hospitals and health care providers. Our contracts will offer tiered pricing
which may include lower fees per scan on incremental scans, allowing hospitals
and other health care customers to benefit from increased scan volumes and
provide us with the opportunity to benefit from operating leverage that may be
associated with increased scan volumes.

         The principal component of our operating costs will include salaries
paid to technologists and drivers, annual system maintenance costs, insurance
and transportation costs. Because a majority of these expenses are fixed,
increased revenues as a result of higher scan volumes may significantly improve
our future profitability potential while lower scan volumes may result in lower
profitability.

         Since inception, we have incurred significant losses and, as of June
30, 1999, had incurred cumulative net losses of $619,763. We expect to
experience operating losses and negative cash flow for the foreseeable future.
We anticipate our losses will increase significantly from current levels as we
expect to incur additional costs and expenses related to staffing,
infrastructure development, marketing and sales activities and other capital
expenditures. As a result, we will need to generate significant revenues to
achieve and maintain profitability.

         We have a limited operating history on which to base an evaluation of
our business and prospects. You must consider our prospects in light of the
risks, expenses and difficulties frequently encountered by companies in their
early stage of development. To address these risks, we must establish, maintain
and expand our customer base, implement and successfully execute our business
and marketing strategy, provide superior customer service, anticipate and
respond to competitive developments and attract, retain and motivate qualified
personnel. We cannot assure you that we will be successful in addressing these
risks, and our failure to do so could have a negative impact on our business,
operating results and financial condition.

RESULTS OF OPERATIONS

OPERATING EXPENSES

         General and Administrative. General and administrative expenses consist
of payroll and related expenses for general corporate functions, including
marketing and sales expenses, finance, facilities expenses, professional
services expenses, insurance and depreciation. We expect general and
administrative expenses to increase as we continue to promote and market our
mobile PET diagnostic services and expand the number of contracted PET mobile
units.

         Any comparison of our results of operations to any previous period is
not meaningful as we recommenced our company and started our current mobile PET
operations as of December 1, 1998.

LIQUIDITY AND CAPITAL RESOURCES

         Since inception, we have financed our operations primarily through
private placements of common stock and from the initial cash put into our
company as a result of Colony Delaware's acquisition of Mobile Nevada. As of
June 30, 1999, we had approximately $1.784 million in cash and cash
equivalents.

                                       12

<PAGE>

         Net cash used in operating activities for the six months ended June 30,
1999 was approximately $1.173 million. The net cash used in operating activities
can be substantially attributed to the net loss incurred to date.

         Net cash used in investing activities was approximately $261,020 in
the seven month period ended June 30, 1999. The net cash used in investing
activities resulted primarily from the initial deposits to equipment and
coach vendors for the initial orders.

         Net cash provided by financing activities was approximately $3.470
million in the seven month period ended June 30, 1999. The net cash provided by
financing resulted primarily from the proceeds from the reverse merger
transaction in January 1999.

         We have experienced a substantial increase in our capital expenditures
since our inception, consistent with our growth in operations and staffing, and
we anticipate that this will continue for the foreseeable future. Additionally,
we continue to evaluate possible expenditures and investments in businesses,
geographic service expansion and service offerings. We cannot be certain that
the underlying assumed levels of revenues and expenses will prove to be
accurate. We may seek additional funding through public or private financings or
other arrangements prior to such time. Adequate funds may not be available when
needed or may not be available on terms favorable to us. If funding is
insufficient at any time in the future, we may be unable to develop or enhance
our service offering, take advantage of business opportunities or respond to
competitive pressures, any of which could have a negative impact on our
business, operating results and financial condition.


                             DESCRIPTION OF PROPERTY

         We lease approximately 3,500 square feet of space in an office building
in San Diego, California for our executive and principal administrative office.
Our principal place of business is located at 2240 Shelter Island Drive, Suite
205, San Diego, California 92106.

                            EXECUTIVE COMPENSATION

         Executive compensation is designed to provide incentives for those
senior members of management who bear responsibility for our goals and
achievements. Our compensation philosophy is based on a base salary, with
opportunity for significant bonuses to reward outstanding performance, and a
stock option program.

EXECUTIVE OFFICER COMPENSATION

         During the fiscal year ended December 31, 1998, three different
individuals served as Chief Executive Officer for our predecessor, Colony
Delaware: Alexander Michie, Brian Hauff and Brent Nelson. Mr. Nelson received no
compensation for his service as Chief Executive Officer, and we believe that
neither Mr. Michie nor Mr. Hauff received any compensation for their service as
Chief Executive Officer. No other executive officers received compensation in
excess of $100,000 during the fiscal year ended December 31, 1998.

EMPLOYMENT AND CONSULTING AGREEMENTS

         On January 1, 1999, we entered into a five-year Employment Agreement
with Paul J. Crowe, our Chief Executive Officer. The Employment Agreement
provides that Mr. Crowe is to receive a salary of $150,000 per year, which
beginning in the calendar year 2000 is to be increased by 10% if the average
market price of our stock in December of the preceding year has increased by at
least 10% above the average market price of our stock in December of the second
preceding year. The Employment Agreement also provides that the Board of
Directors will review and evaluate Mr. Crowe's performance annually and consider
awarding him a discretionary bonus.

         Thomas G. Brown is compensated for his service as our Chief Financial
Officer under a two-year non-exclusive Consulting Agreement dated April 1, 1999.
The Consulting Agreement requires that Mr. Brown devote as much time to our
company's affairs as is reasonably necessary, but he is not required to spend
more than two to three days per week on our premises. Under the Consulting
Agreement, Mr. Brown received a one-time grant of 100,000 shares of our Common
Stock and an option to purchase 250,000 additional shares of our Common Stock at
an exercise price equal to the market price for the shares. He also receives a
salary of $7,500 per month.

         On January 6, 1999, we entered into an Employment Agreement with Jim
Corlett, our Vice President for Mobile Operations. Upon executing the
Employment Agreement, Mr. Corlett received a signing bonus consisting of
100,000 shares of our Common Stock. The Employment Agreement also provides
that Mr. Corlett is to receive a salary of $85,000 per year. In addition, Mr.
Corlett will receive an option to purchase 100,000 shares of our Common Stock
at the end of each of the first three years during the term of the Employment
Agreement. The exercise prices of these options range between $1.10 and $1.90
per share.

         We entered into a Consulting Agreement dated January 29, 1999 with
Michael Baybak and Company, Inc., a California corporation ("Baybak"). The
Consulting Agreement provides that Baybak will provide major media consulting
services for us. The Consulting Agreement is for a period of fifteen (15) months
and provides for compensation in the form of an option to purchase 150,000
shares of our Common Stock at a exercise price of $2.50 per share. The options
expire on January 29, 2004.

         We entered into a Consultancy Agreement with Dr. Piers Nicholas Plowman
dated September 9, 1999. The Consultancy Agreement provides that Dr. Plowman
will oversee our operations in London, England. The Consultancy Agreement ends

exercise price of $3.00 per share; (ii) 25,000 options to purchase our shares of
Common Stock at an exercise price of $1.00 per share; (iii) the right to
subscribe for 10,000 shares of Common Stock at the trading price; (iv) the right

DIRECTOR COMPENSATION

         In April 1999, we granted each of our directors an option to purchase
100,000 shares of our Common Stock. In addition, our directors are reimbursed
for expenses actually incurred in connection with attending meetings of the
Board of Directors.

MEDICAL ADVISORY BOARD COMPENSATION

         We compensate members of our Medical Advisory Board by granting them
options to acquire our Common Stock under our 1999 Stock Option Plan. Members
of the Medical Advisory Board typically receive 25,000 options to purchase
our Common Stock for their first year of service and 10,000 options to
purchase our Common Stock for each subsequent year of service. The exercise
prices for options issued to the Medical Advisory Board range between $1.00
to $3.50 per share.

1999 STOCK OPTION PLAN

         Our 1999 Stock Option Plan (the "1999 Plan") authorizes us to grant to
our directors, employees, consultants and advisors both incentive and
non-qualified stock options to purchase shares of our Common Stock. As of
September 30, 1999, our Board of Directors reserved 3,000,000 shares for
issuance under the 1999 Plan, of which 2,344,000 shares were subject to
outstanding options and 656,000 shares remained available for future grants. Our
Board of Directors or a committee appointed by the Board (the "Plan
Administrator") administers the 1999 Plan. The Plan Administrator selects the
recipients to whom options are granted and determines the number of shares to be
awarded. Options granted under the 1999 Plan are exercisable at a price
determined by the Plan Administrator at the time of the grant, but in no event
will the option price for any incentive stock option be lower than the fair
market value for our Common Stock on the date of the grant. Options become
exercisable at such times and in such installments as the Plan Administrator
provides in the terms of each individual option agreement. In general, the Plan
Administrator is given broad discretion to issue options and to accept a wide
variety of consideration (including shares of Common Stock of the Company and
promissory notes) in payment for the exercise price of options.

                CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         Brent Nelson, a director of our company, is the President of
Northwest Capital Partners, LLC. On December 15, 1998, we entered into a
Consulting Agreement under which Northwest agreed to advise us financially
and assist us in arranging financing for our business operations. The
Consulting Agreement has a three-year term, and Northwest has a right of
first refusal to consult with the Company regarding financings for three
years throughout the duration of the Consulting Agreement. The Consulting
Agreement provides for payment of monthly consulting fees to Northwest in the
amount of $5,000 per month. Commencing in April of 1999, Northwest has waived
payment of these monthly fees. The fee provision is subject to extension for
36 months upon the closing of certain financing transactions set forth in the
Consulting Agreement. In addition, the Consulting Agreement provides that
Northwest is to be granted up to 2,200,000 shares of our Common Stock if it
achieves certain milestones related to locating financing for our business,
of which 1,200,000 shares have been granted to Northwest to date. Northwest's
obligations under the Consulting Agreement are subject to certain conditions
to be performed by us, including refraining from modifying our capital
structure without Northwest's prior written consent. In addition, the
Consulting Agreement provides that for three years after the occurrence of
certain milestones set forth in the Consulting Agreement, if we desire to
issue new shares of stock or any of any of our officers or directors who hold
5% or more of our common stock ("Principal Stockholders") desire to transfer
their shares of our stock to a third party, we and the Principal Stockholders
are required to first offer such shares to the Principal Stockholders or us
(as applicable), and then to Northwest. Finally, the Consulting Agreement
provides that Northwest is entitled to nominate a director for our board of
directors for a period of five years.

         In December of 1998, Northwest Capital Partners, LLC made a
non-interest bearing loan to us in the amount of $50,000. We repaid the loan
in January of 1999.

         Paul J. Crowe, the CEO and a director of our company, is the
Chairman, a director and majority shareholder of the London Radiosurgical
Centre Ltd. Effective July 30, 1999, we loaned $137,319.09 to the London
Radiosurgical Centre pursuant to a Promissory Note dated September 1, 1999.
The Promissory Note provides that the unpaid principal balance on the loan
bears interest at the rate of 8% per year. The loan is due to be repaid on
October 28, 1999.

         We have an 8% interest in a subordinated equity participation in
London Radiosurgical Centre Ltd. The subordinated equity participation is in
the amount of $200,000. The maximum investment of $2,500,000 will be returned
to investors from net income for distribution, after which investors will
receive 60% of net income for distribution. According to the terms of the
participation agreement, net income for distribution is equal to net income
less equipment financing payments, operating expenses, reserve capital and
taxes.

         Thomas G. Brown, the CFO and a director of our Company, is currently
employed as an investment banker by Wyndham Capital Corporation, which
prepared a Confidential Information Memorandum for our company in March 1999
at a cost to us of $3,500.

         In April 1999, we issued 200,000 shares of our common stock to
Northwest Capital Partners, LLC as a result of the exercise of stock options
granted to it by Colony Delaware in December 1998. See "Recent Sales of
Unregistered Securities."

                            DESCRIPTION OF SECURITIES

         We are authorized to issue 20,000,000 shares of Common Stock, $.0001

Holders of Common Stock are entitled to dividends, pro rata, when, as and if
declared by the Board of Directors out of funds available therefor. Holders
of Common Stock are entitled to cast one vote for each share held at all
stockholder meetings for all purposes, including the election of directors.
The holders of more than 50% of the Common Stock issued and outstanding and
entitled to vote, present in person or by proxy, constitute a quorum at all
meetings of stockholders. The vote of the holders of a majority of Common
Stock present at such a meeting will decide any question brought before such
meeting, except for certain actions such as amendments to the Company's
Certificate of Incorporation, mergers or dissolutions which require the vote
of the holders of a majority of the outstanding Common Stock. Upon
liquidation or dissolution, the holder of each outstanding share of Common

                                       17

Stock will be entitled to share equally in the assets of the Company legally
available for distribution to such stockholder after payment of all
liabilities. Holders of Common Stock are not granted any preemptive,

                    INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Under the Delaware General Corporation Law and our Certificate of
Incorporation, our directors will have no personal liability to us or our
stockholders for monetary damages incurred as the result of the breach or
alleged breach by a director of his "duty of care." This provision does not
apply to the directors' (i) acts or omissions that involve intentional
misconduct or a knowing and culpable violation of law, (ii) acts or omissions
that a director believes to be contrary to the best interests of the
corporation or its stockholders or that involve the absence of good faith on
the part of the director, (iii) approval of any transaction from which a
director derives an improper personal benefit, (iv) acts or omissions that
show a reckless disregard for the director's duty to the corporation or its
stockholders in circumstances in which the director was aware, or should have
been aware, in the ordinary course of performing a director's duties, of a
risk of serious injury to the corporation or its stockholders, (v) acts or
omissions that constituted an unexcused pattern of inattention that amounts
to an abdication of the director's duty to the corporation or its
shareholders, or (vi) approval of an unlawful dividend, distribution, stock
repurchase or redemption. This provision would generally absolve directors of
personal liability for negligence in the performance of duties, including
gross negligence.

         The effect of this provision in our Certificate of Incorporation is
to eliminate the rights of our company and our stockholders (through
stockholder's derivative suits on behalf of our company) to recover monetary
damages against a director for breach of his fiduciary duty of care as a
director (including breaches resulting from negligent or grossly negligent
behavior) except in the situations described in clauses (i) through (vi)
above. This provision does not limit nor eliminate the rights of our company
or any stockholder to seek non-monetary relief such as an injunction or
rescission in the event of a breach of a director's duty of care. In
addition, our Certificate of Incorporation provide that if the Delaware
General Corporation Law is amended to authorize the future elimination or
limitation of the liability of a director, then the liability of the
directors will be eliminated or limited to the fullest extent permitted by
the law, as amended. The Delaware General Corporation Law grants corporations
the right to indemnify their directors, officers, employees and agents in
accordance with applicable law.

         Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers or persons controlling
our Company pursuant to the foregoing provisions, we have been informed 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.

                  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS
                     ON ACCOUNTING AND FINANCIAL DISCLOSURE

         We have not had any disagreements with our independent outside
auditors since inception. After Colony Delaware acquired Mobile Nevada, we
changed our independent outside auditor to Peterson & Co.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS


To The Board of Directors
Mobile P.E.T. Systems, Inc.

We have audited the accompanying consolidated balance sheet of Mobile P.E.T.
Systems, Inc., formerly Colony International Incorporated and subsidiaries (a
development stage company) as of June 30, 1999, and the related consolidated
statement of operations, shareholders' equity and cash flows for the period
December 1, 1998 (date of recommencement) to June 30, 1999. 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 audit to
obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements.
An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Mobile
P.E.T. Systems, Inc. and its subsidiaries (a development stage company) as of
June 30, 1999, and the results its operations and its cash flows for the
period December 1, 1998 (date of recommencement) to June 30, 1999, in
conformity with generally accepted accounting principles.

1995, and Mobile P.E.T. Systems, Inc., a wholly owned subsidiary incorporated
in the State of Nevada on December 1, 1998. The Company and subsidiaries were

to hospitals and other health care providers on a mobile, shared user basis.
The Company's PET services will include the provision of high technology
imaging systems, technologists to operate the imaging systems, the management
of day-to-day operations and educational and marketing support.

30, 1999 have been principally devoted to organizational activities, raising
capital, and marketing efforts. Management anticipates incurring substantial
additional losses as it pursues its development efforts.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

         The consolidated financial statements include the accounts of the
Company and its wholly owned subsidiaries. All significant intercompany
transactions have been eliminated in consolidation.

CASH AND CASH EQUIVALENTS

         The Company considers all highly liquid debt instruments purchased
with a maturity of three months or less to be cash and cash equivalents.

PROPERTY, EQUIPMENT AND LEASEHOLD IMPROVEMENTS

         Property and equipment are recorded at cost less depreciation and
amortization. Depreciation and amortization are accounted for on the
straight-line method based on estimated useful lives. The amortization of
leasehold improvements is based on the shorter of the lease term or the life
of the improvement. Betterments and large renewals, which extend the life of
an asset, are capitalized; whereas, maintenance and repairs and small
renewals are expensed as incurred.

ESTIMATES

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

INCOME TAXES

         The Company accounts for income taxes under Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes." This statement
requires an asset and liability approach to account for income taxes. The
Company provides deferred income taxes for temporary differences that will
result in taxable or deductible amounts in future years based on the
reporting of certain costs in different periods for financial and income tax
purposes.

pooling of interests. The Company's consolidated financial statements have
been restated for all periods prior to the business combination and include
the combined results of Mobile P.E.T. Systems, Inc., formerly Colony
International Incorporated and American Coin & Stamp Ventures, Inc., Colony

                            ACQUISITION AGREEMENT

    AGREEMENT dated December 22nd, 1998 (the "Agreement"), by, between and
among COLONY INTERNATIONAL, INC., a company incorporated under the laws of
the State of Delaware (hereinafter referred to as "COLONY"); the person
listed on Exhibit "A" attached hereto and made a part hereof, being the sole
officer of COLONY (hereinafter referred to as "MANAGEMENT"); and MOBILE PET
SYSTEMS, INC., a company incorporated under the laws of the state of Nevada
(hereinafter referred to as "MPET"); and the persons listed on Exhibit "A-1"
attached hereto and made a part hereof, (hereinafter referred to as the
"SELLERS").

    WHEREAS, the SELLERS own a total of 7,000,000 shares of common stock,
$0.001 par value, of MPET, said shares being 100% of the issued and
outstanding common stock of MPET; and

    WHEREAS, the SELLERS desire to sell and COLONY desires to purchase one
hundred (100%) percent of such shares;

    NOW, THEREFORE, in consideration of the mutual covenants, agreements,
representations and warranties herein contained, the parties hereby agree as
follows:

    1. PURCHASE AND SALE. The SELLERS hereby agree to sell, transfer, assign
and convey to COLONY and COLONY hereby agrees to purchase and acquire from
the SELLERS, a total of 7,000,000 shares of Common Stock of MPET, which
equals one hundred percent (100%) percent of all of MPET's currently issued
and outstanding common stock (the "MPET Common Shares"), in a tax-free
stock-for-stock acquisition.

    2. PURCHASE PRICE. The aggregate purchase price to be paid by COLONY for
the MPET Common Shares shall be 7,000,000 shares of COLONY voting Class A
Common Stock (the "COLONY Common Shares"). The COLONY Common Shares will be
issued to the individual SELLERS in accordance with Exhibit "A-1" attached
hereto.

    3. WARRANTIES, REPRESENTATIONS AND COVENANTS OF MPET AND MPET PRINCIPALS.
In order to induce COLONY to enter into this Agreement and to complete the
transaction contemplated hereby, MPET and its principal executive officers
(hereinafter referred to as the "MPET PRINCIPALS"), jointly and severally
warrant and represent to COLONY that:

       (a)  ORGANIZATION AND STANDING. MPET is a corporation duly organized,
validly existing and in good standing under the laws of the state of Nevada,
is qualified to do business as a foreign corporation in every other state or
jurisdiction in which it operates to the extent required by the laws of such
states and jurisdictions, and has full power and authority to carry on its
business as now conducted and to own and operate its assets, properties and
business. Attached hereto as Exhibit "B" are true and correct copies of MPET's
Certificate of Incorporation, amendments thereto and all current By-laws of
MPET. No changes thereto will be made in any of the Exhibit "B" documents
before the Closing. MPET has no subsidiaries or any investments or ownership
interests in any corporation, partnership, joint venture or other business
enterprise which is material to its business.

<PAGE>

       (b) CAPITALIZATION. As of the Closing Date, MPET's entire authorized
equity capital consists of 13,000,000 shares of Common Stock, $0.001 par
value, of which 7,000,000 shares of Common Stock will be outstanding as of
the Closing.  As of the Closing Date, there will be no other voting or equity
securities authorized or issued, nor any authorized or issued securities
convertible into voting stock, and no outstanding subscriptions, warrants,
calls, options, rights, commitments or agreements by which MPET or the
SELLERS are bound, calling for the issuance of any additional shares of
common stock or any other voting or equity security, except as set forth in
Exhibit "MPET-S", attached hereto. The 7,000,000 issued and outstanding MPET
Common Shares to be transferred by SELLERS constitutes one hundred (100.0%)
percent of the currently issued and outstanding shares of Common Stock of
MPET, which includes, inter alia, that same percentage of MPET's voting
power, right to receive dividends, when, as and if declared and paid, and the
right to receive the proceeds of liquidation attributable to common stock, if
any. After becoming management of COLONY, MPET'S management will not further
reverse split COLONY's common stock for at least 12 months.

       (c) OWNERSHIP OF MPET SHARES.  Each SELLER warrants and represents,
severally, that as of the date hereof, such SELLER is the sole owner of the
MPET Common shares listed by his or her name on Exhibit "A-1", free and clear
of all liens, encumbrances, and restrictions whatsoever, except that the MPET
Common Shares so listed have not been registered under the Securities Act of
1933, as amended (the "'33 Act"), or any applicable State Securities laws. By
SELLERS' transfer of the MPET Common Shares to COLONY pursuant to this
Agreement, COLONY will thereby acquire 100% of the outstanding capital stock
of MPET, free and clear of all liens, encumbrances and restrictions of any
nature whatsoever, except by reason of the fact that the MPET Common Shares
will not have been registered under the `33 Act, or any applicable State
securities laws.

       (d) TAXES. MPET has filed all federal, state and local income or other
tax returns and reports that it is required to file with all governmental
agencies, wherever situate, and has paid or accrued for payment all taxes as
shown on such returns, such that a failure to file, pay or accrue will not
have a material adverse effect on MPET. MPET's income tax returns have never
been audited by any authority empowered to do so.

       (e) PENDING ACTIONS. There are no material legal actions, lawsuits,
proceedings or investigations, either administrative or judicial, pending or
threatened, against or affecting MPET, or against the MPET PRINCIPALS that
arise out of their operation of MPET, except as described in Exhibit "C"
attached hereto. MPET is not knowingly in material violation of any law,
material ordinance or regulation of any kind whatever, including, but not
limited to laws, rules and regulations governing the sale of its services,
the `33 Act, the Securities Exchange Act of 1934, as amended (the "`34 Act"),
the Rules and Regulations of the U.S. Securities and Exchange Commission
("SEC"), or the Securities Laws and Regulations of any state or nation.

       (f) GOVERNMENTAL REGULATION. MPET holds the licenses and registrations
set forth on Exhibit "D" hereto from the jurisdictions set forth therein,
which licenses and registrations are all of the licenses and registrations
necessary to permit MPET to conduct its current business. All of such

                                        2


<PAGE>

licenses and registrations are in full force and effect, and there are no
proceedings, hearings or other actions pending that may affect the validity
or continuation of any of them. No approval of any other trade or
professional association or agency of government other than as set forth on
Exhibit "D" is required for any of the transactions effected by this
Agreement, and the completion of the transactions contemplated by this
Agreement will not, in and of themselves, affect or jeopardize the validity
or continuation of any of them.

       (g) OWNERSHIP OF ASSETS. Except as set forth in Exhibit "E" attached
hereto, MPET has good, marketable title, without any liens or encumbrances of
any nature whatever, to all of the following, if any; its assets, properties
and rights of every type and description, including, without limitation, all
cash on hand and in banks, certificates of deposit, stocks, bonds, and other
securities, good will, customer lists, its corporate name and all variants
thereof, trademarks and trade names, copyrights and interests thereunder,
licenses and registrations, pending licenses and permits and applications
therefor, investments, processes, know-how, trade secrets, real estate and
interests therein and improvements thereto, machinery, equipment, vehicles,
notes and accounts receivable, fixtures, rights under agreements and leases,
franchises, all rights and claims under insurance policies and other
contracts of whatever nature, rights in funds of whatever nature, books and
records and all other property and rights in funds of whatever nature, books
and records and all other property and rights of every kind and nature owned
or held by MPET as of this date, and will continue to hold such title on and
after the completion of the transactions contemplated by this Agreement; nor,
except in the ordinary course of its business, has MPET disposed of any such
asset since the date of the most recent balance sheet described in Section 3(o)
of this Agreement.

       (h) NO INTEREST IN SUPPLIERS, CUSTOMERS, LANDLORDS OR COMPETITORS.
Neither the MPET PRINCIPALS nor any member of their families have any
material interest of any nature whatever in any supplier, customer, landlord
or competitor of MPET.

       (i) NO DEBT OWED BY MPET TO MPET PRINCIPALS. Except as set forth in
Exhibit "F" attached hereto, MPET does not owe any money, securities, or
property to either the MPET PRINCIPALS or any member of their families or to
any company controlled by such a person, directly or indirectly. To the
extent that MPET may have any undisclosed liability to pay any sum or
property to any such person or entity or any member of their families such
liability is hereby forever irrevocably released and discharged.

       (j) CORPORATE RECORDS. All of MPET's books and records, including,
without limitation, its books of account, corporate records, minute book,
stock certificate books and other records are up-to-date, complete and
reflect accurately and fairly the conduct of its business in all material
respects since its date of incorporation.

       (k) NO MISLEADING STATEMENTS OR OMISSIONS. Neither this Agreement nor
any financial statement, exhibit, schedule or document attached hereto or
presented to COLONY in connection herewith, contains any materially
misleading statement, or omits any fact or statement necessary to make the
other statements or facts therein set forth not materially misleading.

       (l) VALIDITY OF THIS AGREEMENT. All corporate and other proceedings
required to be

Agreement have been duly and properly taken. This Agreement has been duly
executed by the SELLERS and by MPET, and constitutes the valid and binding
obligation of each of them, enforceable in accordance with its terms except
to the extent limited by applicable bankruptcy, reorganization, insolvency,
moratorium or other laws relating to or effecting generally the enforcement
of creditors rights. The execution and delivery of this Agreement and the
carrying out of its purposes will not result in the breach of any of the terms
or conditions of, or constitute a default under or violate, MPET's Certificate
of Incorporation or By-Laws, or any material agreement, lease, mortgage,
bond, indenture, license or other material document or undertaking, oral or
written, to which MPET or the SELLERS is a party or is bound or may be
affected, nor will such execution, delivery and carrying out violate any law,
rule or regulation or any order, writ, injunction or decree, of any court,
regulatory agency or other governmental body; and the business now conducted
by MPET can continue to be so conducted after completion of the transaction
contemplated hereby, with MPET as a wholly-owned subsidiary of COLONY.

       (m) CONSENTS AND APPROVALS; COMPLIANCE WITH LAWS. Neither MPET nor the
SELLERS are required to make any filing with, or obtain the consent or
approval of, any person or entity as a condition to the consummation of the
transactions contemplated by this Agreement.  The business of MPET has been

'33 Act and the '34 Act) and for the period from inception to November 30,
1998 audited by independent certified public accountants with SEC experience.

(attached hereto as Exhibit "L") accurately describes MPET's business,
assets, proposed operations and management as of the date thereof; since the

    4.  WARRANTIES, REPRESENTATIONS AND COVENANTS OF COLONY AND MANAGEMENT
OF COLONY ("MANAGEMENT"). In order to induce the SELLERS and MPET to enter
into this Agreement and to complete the transaction contemplated hereby,
COLONY and MANAGEMENT jointly and severally warrant, represent and covenant
to MPET and SELLERS that:

                                        4

<PAGE>

    (a) ORGANIZATION AND STANDING. COLONY is a corporation duly organized,
validly existing and in good standing under the laws of the State of
Delaware, is qualified to do business as a foreign corporation in every other
state and jurisdiction in which it operates to the extent required by the
laws of such states or jurisdictions, and has full power and authority to
carry on its business as now conducted and to own and operate its assets,
properties and business. COLONY has no subsidiaries or any other investments
or ownership interests in any corporation, partnership, joint venture or
other business enterprise.

    (b) CAPITALIZATION. COLONY's entire authorized equity capital consists of
100,000,000 shares of Class A Common Stock, $0.0001 par value, of which
4,144,474 shares will be outstanding immediately before the closing; and
10,000,000 shares of Preferred Stock, none of which are issued and
outstanding now or will be at closing. At or as of the Closing, the existing
COLONY Board of Directors will authorize the issuance of 7,000,000 restricted
Class A Common shares to MPET's shareholders. As of the Closing, giving
effect to the 7,000,000 Class A Common Shares issued to SELLERS hereunder,
COLONY will have authorized 100,000,000 shares of Class A Common Stock,
$0.0001 par value and 10,000,000 shares of Preferred Stock, and will have
issued and outstanding 11,144,474 shares of voting Class A Common Stock,
$0.0001 par value and no shares of Preferred Stock issued. Upon issuance, all
of the COLONY Class A Common Stock will be validly issued, fully paid and
non-assessable. The relative rights and preferences of COLONY's equity
securities are set forth on the Certificate of Incorporation, as amended and
COLONY's By-laws (Exhibit "H" hereto). There are no other voting or equity
securities authorized or issued, nor any authorized or issued securities
convertible into voting stock, and no outstanding subscriptions, warrants,
calls, options, rights, commitments or agreements by which COLONY is bound,
calling for the issuance of any additional shares of common stock or any
other voting or equity security. The By-laws of COLONY provide that a simple
majority of the shares voting at a stockholders' meeting at which a quorum is
present may elect all of the directors of COLONY. Cumulative voting is not
provided for by the By-Laws or Certificate of Incorporation of COLONY.
Accordingly, as of the Closing the 7,000,000 Class A Common Shares being
issued to and acquired by the SELLERS will constitute 62.81% of the
11,144,474 shares of COLONY Class A Common Stock which will then be issued
and outstanding which includes, inter alia, that same percentage of COLONY's
voting power (subject to the provisions regarding cumulative rights), right
to receive dividends, when, as and if declared and paid, and the right to
receive the proceeds of liquidation attributable to common stock, if any.

    (c) OWNERSHIP OF SHARES. By COLONY's issuance of the COLONY Common Shares
to the SELLERS pursuant to this Agreement, the SELLERS will thereby acquire
good, absolute marketable title thereto, free and clear of all liens,
encumbrances and restrictions of any nature whatsoever, except by reason of
the fact that such COLONY shares will not have been registered under the '33
Act, or any applicable state securities laws.

    (d) SIGNIFICANT AGREEMENTS. COLONY is not and will not at Closing be
bound by any of the following:

         (i)    Employment, advisory or consulting contract (except as

         (vi)   Contract, agreement, understanding, commitment or

and to pay in full at or before the Closing.

inspection by MPET's authorized representatives prior to the Closing as
provided by Section 4(l) herein, and will be delivered to COLONY's new
management at the Closing.

        (i) NO MISLEADING STATEMENTS OR OMISSIONS. Neither this Agreement nor
any financial statement, exhibit, schedule or document attached hereto or
presented to MPET in connection herewith contains any materially misleading
statement, or omits any fact or statement necessary to make the other
statements or facts therein set forth not materially misleading.

        (j) VALIDITY OF THIS AGREEMENT. All corporate and other proceedings
required to be taken by COLONY in order to enter into and to carry out this
Agreement will have been duly and properly taken at or before the Closing.
This Agreement has been duly executed by COLONY, and constitutes a valid and
binding obligation of COLONY enforceable in accordance with its terms. The
execution and delivery of this Agreement and the carrying out of its purposes
will not result in the breach of any of the terms or conditions of, or
constitute a default under or violate, COLONY's Certificate of Incorporation

other document or undertaking, oral or written, to which COLONY is a party or
is bound or may be affected, nor will such execution, delivery and carrying
out violate any law, rule or regulation or any order, writ, injunction or
decree of any court, regulatory agency or other governmental body.

        (k) CONSENTS AND APPROVALS; COMPLIANCE WITH LAWS. Neither COLONY nor

the issued and outstanding common stock of COLONY; and

     WHEREAS, the Sellers desire to sell and AMERICAN desires to purchase one

     NOW, THEREFORE, in consideration of the mutual covenants, agreements,
representations and warranties herein contained, the parties hereby agree as

     2.     PURCHASE PRICE.  The aggregate purchase price to be paid by

     3.     WARRANTIES AND REPRESENTATIONS OF COLONY AND SELLERS  In order to

organized, validly existing and in good standing under the laws of the State
of Nevada, is qualified to do business as a foreign corporation in British
Columbia and in every other state or jurisdiction in which it operates to the

<PAGE>

            (b)   CAPITALIZATION.  As of the date hereof, COLONY's entire
authorized equity capital consists of 60,000,000 shares of Common Stock
$0.007 par value, of which 901,986 shares of Common Stock are issued and
outstanding.  As of the Closing Date, there will be no other voting or equity
securities authorized or issued, nor any authorized or issued securities
convertible into voting stock, and no outstanding subscriptions, warrants;
calls, options, rights, commitments or agreements by which COLONY or the
Sellers are bound, calling for the issuance of any additional shares of
common stock or any other voting or equity security, except for the shares to
be issued to the Consultants which shares will be exchanged for a total of
1,300,000 shares of AMERICAN stock.  All of such Colony Common Shares have
been duly authorized and validly issued and are fully paid and non-assessable
and were not issued in violation of any preemptive rights or any applicable
securities laws.  The 901,986 issued and outstanding COLONY Common Shares
constitute one hundred (100%) percent of the equity capital of COLONY, which
includes, INTER ALIA, one hundred (100%) percent of COLONY's voting power,
right to receive dividends, when, as and if declared and paid, and the right
to receive the proceeds of liquidation attributable to common stock, if any.

            (c)   OWNERSHIP OF COLONY SHARES.  As of the date hereof, the
Sellers are the sole owners of the COLONY Common Shares, free and clear of
all liens, encumbrances, and restrictions whatsoever, except that the COLONY
Common Shares have not been registered under the Securities Act of 1933, as
amended (the "'33 Act"), or any applicable State Securities laws.  By the
transfer of the COLONY Common Shares to AMERICAN pursuant to this Agreement,
AMERICAN will thereby acquire good and marketable title to 100% of the
capital stock of COLONY, free and clear of all liens, encumbrances and
restrictions of any nature whatsoever, except by reason of the fact that the
COLONY Common Shares will not have been registered under the '33 Act, or any
applicable State Securities laws.

            (d)   TAXES.   COLONY has filed all federal, state and local
income or other tax returns and reports that it is required to file with all
governmental agencies, wherever situated, and has paid or accrued for payment
all taxes as shown on such returns, such that a failure to file, pay or
accrue will not have a Material Adverse Effect on COLONY.  Such returns have
been prepared in accordance with the applicable tax laws and rules and
regulations thereunder to which COLONY is subject and Sellers have delivered
true and complete copies of all such tax returns to AMERICAN.

            (e)   PENDING ACTIONS.   There are no material legal actions,
lawsuits, proceedings or investigations, either administrative or judicial,
pending or threatened, against or affecting COLONY, or against COLONY's
Officers or Directors or the Sellers that arise out of their operation of
COLONY, except as described in Exhibit "C" attached hereto.  COLONY is not
knowingly in violation of any law, material ordinance or regulation of any
kind whatever, including, but not limited to laws, rules and regulations
governing the sale of its products and/or services, the '33 Act, the
Securities Exchange Act of 1934 (the "'34 Act") as amended, the Rules and
Regulations of the U.S. Securities and Exchange Commission ("SEC"), or the
securities laws and regulations of any state.  Neither COLONY nor Sellers are

award of any court, arbitrator or administrative, governmental or regulatory
authority or body.

            (f)   GOVERNMENTAL REGULATION.   COLONY holds the licenses and
registrations set forth on Exhibit "D" hereto from the jurisdictions set
forth therein, which licenses and registrations are all of the licenses and
registrations necessary to permit COLONY to conduct its current business.
All of such licenses and registrations are in full force and effect, and
there are no proceedings, hearings or other actions pending that may affect
the validity or continuation of any of them.  No approval of any other trade
or professional association or agency of government other than as set forth
on Exhibit "D" is required for any of the transactions effected


                                      -2-

<PAGE>

by this Agreement, and the completion of the transactions contemplated by this
Agreement will not, in and of themselves, affect or jeopardize the validity or
continuation of any of them.

         (g)      OWNERSHIP OF ASSETS. Except as set forth in Exhibit "E",
COLONY has good, marketable title, without any liens or encumbrances of any
nature whatever, to all of the following, if any: its assets, properties and

transactions contemplated by this Agreement; nor, except in the ordinary course
of its business, has COLONY disposed of any such asset since the date of the
most recent balance sheet described in Section 3(o) of this Agreement. COLONY's
waste disposal process does not infringe any outstanding patent held by any
other person or entity.

         (h)      NO INTEREST IN SUPPLIERS, CUSTOMERS, LANDLORDS OR COMPETITORS.
Neither the Sellers nor any member of their families have any interest of any
nature whatever in any supplier, customer, landlord or competitor of COLONY.

         (i)      NO DEBT OWED BY COLONY TO SELLERS. Except as set forth in

been duly executed by the Sellers and by COLONY, and constitutes the valid and
binding obligation of each of them, except to the extent limited by applicable
bankruptcy, reorganization, insolvency, moratorium or other laws relating to or
effecting generally the enforcement of creditors rights. The execution and
delivery of this Agreement and the carrying out of its purposes will not result
in the breach of any of the terms or conditions of, or constitute a default
under or violate, COLONY's Certificate of Incorporation or By-Laws, or any

     4.     WARRANTIES AND REPRESENTATIONS OF AMERICAN.  In order to induce

            (b)     CAPITALIZATION.  AMERICAN's entire authorized equity
capital consists of 100,000,000 shares of voting common stock, $.0001 par

shares to COLONY's current shareholders and 1,300,000 shares to Consultants
in payment for their services in connection with this transaction); and (c)

(including shares reserved for exercise of the aforesaid options).  Upon

and non-assessable.  The relative rights and preferences of AMERICAN's equity
securities are set forth on the Certificate of Incorporation, as amended and

quorum is present may elect all of the directors of AMERICAN.  Cumulative

AMERICAN.  Accordingly, as of the Closing the 9,500,000 shares being issued
to and acquired by the Sellers (including the shares issued to Consultants)
will constitute 95% of the 10,000,000 shares of AMERICAN which will then be
issued and outstanding, (including after giving effect to the issuance of the
above-stated number of shares as payment for all consulting fees and
commissions) which includes, INTER ALIA, that same percentage of AMERICAN's
voting power, right to receive dividends, when, as and if declared and paid,
and the right to receive the proceeds of liquidation attributable to common

                           MOBILE PET SYSTEMS, INC.

                           AMENDED & RESTATED BYLAWS


                                   ARTICLE 1
                                 STOCKHOLDERS

         1. STOCK CERTIFICATES. Certificates representing stock in the
corporation shall be signed by, or in the name of, the corporation by the
Chairman or Vice-Chairman of the Board of Directors (the "BOARD"), if any, or by
the President or a Vice-President and by the Treasurer or an Assistant Treasurer
or the Secretary or an Assistant Secretary of the corporation. Any or all the
signatures on any such certificate may be a facsimile. In case of any officer,
transfer agent, or registrar who has signed or whose facsimile signature has
been placed on a certificate shall have ceased to be such officer, transfer
agent, or registrar before such certificate is issued, it may be issued by the
corporation with the same effect as if he were such officer, transfer agent, or
registrar at the date of issue.

            Whenever the corporation shall be authorized to issue more than
one class of stock or more than one series of any class of stock, and
whenever the corporation shall issue any shares of its stock as partly paid
stock, the certificates representing shares of any such class or series or of
any such partly paid stock shall set forth thereon the statements prescribed
by the General Corporation Law. Any restrictions on the transfer or
registration of transfer of any shares of stock of any class or series shall
be noted conspicuously on the certificate representing such shares.

            The corporation may issue a new certificate of stock or
uncertified shares in place of any certificate theretofore issued by it,
alleged to have been lost, stolen, or destroyed, and the Board may require
the owner of the lost, stolen, or destroyed certificate, or his legal
representative, to give the corporation a bond sufficient to indemnify the
corporation against any claim that may be made against it on account of the
alleged loss, theft, or destruction of any such certificate or the issuance
of any such new certificate or uncertificated shares.

         2. UNCERTIFIED SHARES. Subject to any conditions imposed by the General
Corporation Law, the Board of the corporation may provide by resolution or
resolutions that some or all of any or all classes or series of the stock of the
corporation shall be uncertificated shares. Within a reasonable time after the
issuance or transfer of any uncertificated shares, the corporation shall send to
the registered owner thereof any written notice prescribed by the General
Corporation Law.


                                                                     Page 1 of 9

<PAGE>

         3. FRACTIONAL SHARES. The corporation may, but shall not be required
to, issue fractions of a share. If the corporation does not issue fractions of a
share, it shall (1) arrange for the disposition of fractional interests by those
entitled thereto, (2) pay in cash the fair value of fractions of a share as of
the time when those entitled to receive such fractions are determined, or (3)
issue scrip or warrants in registered form (either represented by a certificate
or uncertificated) or bearer form (represented by a certificate) which shall
entitle the holder to receive a full share on the surrender of such scrip or
warrants aggregating a full share. A certificate for a fractional share or an
uncertificated fractional share shall, but scrip or warrants shall not unless
otherwise provided therein, entitle the holder to exercise voting rights, to
receive dividends thereon, and to participate in any of the assets of the
corporation in the event of liquidation. The Board may cause scrip or warrants
to be issued subject to the conditions that they shall become void if not
exchanged for certificates representing full shares or uncertificated full
shares before a specified date, or subject to the conditions that the shares for
which scrip or warrants are exchangeable may be sold by the corporation and the
proceeds thereof distributed to the holders of scrip or warrants, or subject to
any other conditions which the Board may impose.

         4. STOCK TRANSFERS. On compliance with provisions restricting the
transfer or registration of transfer of shares of stock, if any, transfers or
registration of transfers of shares of stock of the corporation shall be made
only on the stock ledger of the corporation by the registered holder thereof, or
by his attorney thereunto authorized by power of attorney duly executed and
filed with the Secretary of the corporation or with a transfer agent or a
registrar, if any, and, in the case of shares represented by certificates, on
surrender of the certificate or certificates for such shares of stock properly
endorsed and the payment of all taxes due thereon.

         5. RECORD DATE. In order that the corporation may determine the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, the Board may fix a record date, which record date
shall not precede the date on which the resolution fixing the record date is
adopted by the Board, and which record date shall not be more than sixty (60)
nor less than ten (10) days before the date of such meeting. If no record date
is fixed by the Board, the record date for determining stockholders entitled to
notice of or to vote at a meeting of stockholders shall be at the close of
business on the day next preceding the day on which notice is given, or, if
notice is waived, at the close of business on the day next preceding the day on
which the meeting is held. A determination of stockholders of record entitled to
notice of or to vote at a meeting of stockholders shall apply to any adjournment
of the meeting; provided, however, that the Board may fix a new record date for
the adjourned meeting. In order that the corporation may determine the
stockholders entitled to consent to corporate action in writing without a
meeting, the Board may fix a record date, which record date shall not precede
the date on which the resolution fixing the record date is adopted by the Board,
and which date shall not be more than ten (10) days after the date on which the
resolution fixing the record date is adopted by the Board. If no record date has
been fixed by the Board, the record date for determining the stockholders
entitled to consent to corporate action in writing without a meeting, when no
prior action by the Board is required by the General Corporation Law, shall be
the first date on which a signed written consent setting forth the action taken
or proposed to be taken is delivered to the corporation by delivery to its
registered office in the State of Delaware, its principal place of business, or
an officer or agent of the corporation having custody of the


                                                                     Page 2 of 9

<PAGE>

book in which proceedings of meetings of stockholders are recorded. Delivery
made to the corporation's registered office shall be by hand or by certified
or registered mail, return receipt requested. If no record date has been
fixed by the Board and prior action by the Board is required by the General
Corporation Law, the record date for determining stockholders entitled to
consent to corporate action in writing without a meeting shall be at the
close of business on the day on which the Board adopts the resolution taking
such prior action, in order that the corporation may determine the
stockholders entitled to receive payment of any dividend or other
distribution or allotment of any rights of the stockholders entitled to
exercise any rights in respect of any change, conversion, or exchange of
stock, or for the purpose of any other lawful action, the Board may fix a
record date, which record date shall not precede the date on which the
resolution fixing the record date is adopted, and which record date shall be
not more than sixty (60) days prior to such action. If no record date is
fixed, the record date for determining stockholders for any such purpose
shall be at the close of business on the day on which the Board adopts the
resolution relating thereto.

         6. MEANING OF TERMS. As used herein in respect of the right to notice
of a meeting of stockholders or a waiver thereof or to participate or vote
thereat or to consent or dissent in writing in lieu of a meeting, as the case
may be, the term "share" or "shares" or "share of stock" or "shares of stock" or
"stockholders" or "stockholders" refers to an outstanding share or shares of
stock and to a holder or holders of record of outstanding shares of stock when
the corporation is authorized to issue only one class of shares of stock, and
said reference is also intended to include any outstanding share or shares of
stock any holder or holders of record of outstanding shares of stock of any
class on which or on whom the certificate of incorporation confers such rights
where there are two or more classes or series of shares of stock or on which or
on whom the General Corporation Law confers such rights notwithstanding that the
certificate of incorporation may provide for more than one class or series of
shares of stock, one or more of which are limited or denied such rights
thereunder; provided, however, that no such rights shall vest in the event of an
increase or a decrease in the authorized number of shares of stock of any class
or series which is otherwise denied voting rights under the provisions of the
certificate of incorporation, except as any provisions of law may otherwise
require.


                                   ARTICLE 2
                             STOCKHOLDER MEETINGS

         1. TIME. The annual meeting shall be held on the date and at the time
fixed, from time to time, by the directors, provided, that the first annual
meeting shall be held on a date within thirteen (13) months after the
organization of the corporation, and each successive annual meeting shall be
held on a date within thirteen (13) months after the date of the preceding
annual meeting. A special meeting shall be held on the date and at the time
fixed by the directors.

         2. PLACE. Annual meetings and special meetings shall be held at such
place, within or without the State of Delaware, as the directors may, from time
to time, fix. Whenever the directors shall fail to fix such place, the meeting
shall be held at the registered office of the corporation in Delaware.


                                                                     Page 3 of 9

<PAGE>

         3. CALL. Annual meetings and special meetings may be called by the
directors or by any officer instructed by the directors to call the meeting.

         4. NOTICE OR WAIVER OF NOTICE. Written notice of all meetings shall be
given, stating the place, date and hour of the meeting and stating the place
within the city or other municipality or community at which the list of
stockholders of the corporation may be examined. The notice of an annual meeting
shall state that the meeting is called for the election of directors and for the
transaction of other business which may properly come before the meeting, and
shall (if any other action which could be taken at a special meeting is to be
taken at such annual meeting) state the purpose or purposes. The notice of a
special meeting shall in all instances state the purpose or purposes for which
the meeting is called. The notice of any meeting shall also include, or be
accompanied by, any additional statements, information, or documents prescribed
by the General Corporation Law. Except as otherwise provided by the General
Corporation Law, a copy of the notice of any meeting shall be given, personally
or by mail, not less than ten (10) days nor more than sixty (60) days before the
date of the meeting, unless the lapse of the prescribed period of time shall
have been waived, and directed to each stockholder at his record address or at
such other address which he may have furnished by request in writing to the
Secretary of the corporation. Notice by mail shall be deemed to be given when
deposited, with postage thereon prepaid, in the United States Mail. If a meeting
is adjourned to another time, not more than thirty (30) days hence, and/or to
another place, and if an announcement of the adjourned time and/or place is made
at the meeting, it shall not be necessary to give notice of the adjourned
meeting unless the directors, after adjournment, fix a new record date for the
adjourned meeting. Notice need not be given to any stockholder who submits a
written waiver of notice signed by him before or after the time stated therein.
Attendance of a stockholder at a meeting of stockholders shall constitute a
waiver of notice of such meeting, except when the stockholder attends the
meeting for the express purpose of objecting, at the beginning of the meeting,
to the transaction of any business because the meeting is not lawfully called or
convened. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the stockholders need be specified in any written
waiver of notice.

         5. STOCKHOLDER LIST. The officer who has charge of the stock ledger of
the corporation shall prepare and make, at least ten (10) days before every
meeting of stockholders, a complete list of the stockholders, arranged in
alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city or other municipality or
community where the meeting is to be held, which place shall be specified in the
notice of the meeting, or if not so specified, at the place where the meeting is
to be held. The list shall also be produced and kept at the time and place of
the meeting during the whole time thereof, and may be inspected by any
stockholder who is present. The stock ledger shall be the only evidence as to
who are the stockholders entitled to examine the stock ledger, the list required
by this section or the books of the corporation, or to vote at any meeting of
stockholders.


                                                                     Page 4 of 9

<PAGE>

         6. CONDUCT OF MEETING. Meetings of the stockholders shall be presided
over by one of the following officers in order of seniority and if present and
acting: the Chairman of the Board, if any, the Vice-Chairman of the Board, if
any; the President, a Vice-President, or, if none of the foregoing is in office
and present and acting, by a chairman to be chosen by the stockholders. The
Secretary of the corporation, or in his absence, an Assistant Secretary, shall
act as secretary of every meeting, but if neither the Secretary nor an Assistant
Secretary is present the Chairman of the meeting shall appoint a secretary of
the meeting.

         7. PROXY. Every stockholder may authorize another person or persons to
act for him by proxy in all matters in which a stockholder is entitled to
participate, whether by waiving notice of any meeting, voting or participating
at a meeting, or expressing consent or dissent without a meeting. Every proxy
must be signed by the stockholder or by his attorney-in-fact. No proxy shall be
voted or acted on after three (3) years from its date unless such proxy provides
for a longer period. A duly executed proxy shall be irrevocable if it states
that it is irrevocable and, if, and only as long as, it is coupled with an
interest sufficient in law to support an irrevocable power. A proxy may be made
irrevocable regardless of whether the interest with which it is coupled is an
interest in the stock itself or an interest in the corporation generally.

         8. INSPECTORS. The directors, in advance of any meeting, may, but need
not, appoint one or more inspectors of election to act at the meeting or any
adjournment thereof. If an inspector or inspectors are not appointed, the person
presiding at the meeting may, but need not, appoint one or more inspectors. In
case any person who may be appointed as an inspector fails to appear or act ,
the vacancy may be filled by appointment made by the directors in advance of the
meeting or at the meeting by the person presiding thereat. Each inspector, if
any, before entering on the discharge of his duties, shall take and sign an oath
faithfully to execute the duties of inspectors at such meeting with strict
impartiality and according to the best of his ability. The inspectors, if any,
shall determine the number of shares of stock outstanding the voting power of
each, the shares of stock represented at the meeting, the existence of a quorum,
the validity and effect of proxies, and shall receive votes, ballots, or
consents, hear and determine all challenges and questions arising in connection
with the right to vote, count and tabulate all votes, ballots, or consents,
determine the result, and so such acts as are proper to conduct the election or
vote with fairness to all stockholders. On request of the person presiding at
the meeting, the inspector or inspectors, if any, shall make a report in writing
of any challenge, question, or matter determined by him or them and execute a
certificate of any fact found by him or them. Except as otherwise required by
subsection (e) of Section 231 of the General Corporation Law, the provisions of
that Section shall not apply to the corporation.

         9. QUORUM. The holders of a majority of the outstanding shares of
stock shall constitute a quorum at a meeting of stockholders for the transaction
of any business. The stockholders present may adjourn the meeting despite the
absence of a quorum.

         10. VOTING. Each share of stock shall entitle the holders thereof to
one vote. Directors shall be elected by a plurality of the vote of the shares
present in person or represented by proxy at the meeting and entitled to vote on
the election of directors. Any other action shall be authorized by a majority of
the votes case except where the General Corporation Law prescribes a different
percentage of votes and/or


                                                                     Page 5 of 9

<PAGE>

a different exercise of voting power, and except as may be otherwise
prescribed by the provisions of the certificate of incorporation and these
Amended & Restated Bylaws ("BYLAWS"). In the election of directors, and for
any other action, voting need not be by ballot.

         11. STOCKHOLDER ACTION WITHOUT MEETINGS. Any action required by the
General Corporation Law to be taken at any annual or special meeting of
stockholders, or any action which may be taken at any annual or special meeting
of stockholders, may be taken without a meeting, without prior notice and
without a vote, if a consent in writing, setting forth the action so taken,
shall be signed by the holders of outstanding stock having not less than the
minimum number of votes that would be necessary to authorize or take such action
at a meeting at which all shares entitled to vote thereon were present and
voted. Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not consented in writing. Action taken pursuant to this paragraph shall be
subject to the provisions of Section 228 of the General Corporation Law.


                                   ARTICLE 3
                                   DIRECTORS

         1. FUNCTIONS AND DEFINITION. The business and affairs of the
corporation shall be managed by or under the direction of the Board of the
corporation. The Board shall have the authority to fix the compensation of the
members thereof. The use of the phrase "whole board" herein refers to the total
number of directors which the corporation would have if there were no vacancies.

         2. QUALIFICATIONS AND NUMBER. A director need not be a stockholder, a
citizen of the United States, or a resident of the State of Delaware. The Board
shall consist of three (3) persons. Thereafter the number of directors
constituting the whole board shall be at least one. Subject to the foregoing
limitation, such number may be fixed from time to time by action of the
stockholders or of the directors, or, if the number is not fixed, the number
shall be three (3). The number of directors may be increased or decreased by
action of the stockholders or of the directors.

         3. ELECTION; TERM. Any director may resign at any time on written
notice to the corporation. Thereafter, directors who are elected at an annual
meeting of stockholders, and directors who are elected in the interim to fill
vacancies and newly created directorships, shall hold office until the next
annual meeting of stockholders and until their successors are elected and
qualified or until their earlier resignation or removal. Except as the General
Corporation Law may otherwise require, in the interim between annual meetings of
stockholders or of special meetings of stockholders called for the election of
directors and/or for the removal of one or more directors and for the filling of
any vacancy in that connection, newly created directorships and any vacancies in
the Board, including unfilled vacancies resulting from the removal of directors
for cause or without cause, may be filled by the vote of a majority of the
remaining directors then in office, although less than a quorum, or by the sole
remaining director.


                                                                     Page 6 of 9

State of Delaware as shall be fixed by the Board.

         3. CALL. No call shall be required for regular meetings for which the

of any, or the President, or of a majority of the directors in office.

         4. NOTICE OR ACTUAL/CONSTRUCTIVE NOTICE; WAIVER. No notice shall be
required for regular meetings for which the time and place have been fixed.

for special meetings in sufficient time for the convenient assembly of the
directors thereat. Notice need not be given to any director or to any member of
a committee of directors who submits a written waiver of notice signed by him
before or after the time stated thereon. Attendance of any such person at a
meeting shall constitute a waiver of notice of such meeting, except when he
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened. Neither the business to be transacted at, nor the purpose
of, any regular or special meeting of the directors need be specified in any
written waiver of notice.

         5. QUORUM AND ACTION. A majority of the whole Board shall constitute a

                             TERMS AND CONDITIONS

FINOVA CAPITAL CORPORATION ("Lessor") agrees to lease to Lessee, and Lessee
agrees to lease from Lessor, the personal property, together with all
attachments, replacements, parts, additions, and accessories ("Equipment")
listed on any Lease Schedule. The words YOU, YOUR, and YOURS mean the Lessee
indicated below. The words WE, US, and OUR refer to the Lessor indicated
above.

     1.  TERM.  The term of this lease will start on the date we sign this
lease ("Lease Commencement Date"). The payments of rent are payable
periodically in advance as stated on any Lease Schedule. You promise to pay
the total amount of all rent payments stated in any Lease Schedule, plus any
other amounts provided for in this lease. This lease cannot be canceled by
you.

     2.  RENT

         (A)  You will pay for use of the Equipment all rent payments and
other amounts provided for in this lease. Consecutive periodic rent payments
will be due on the first day of the month following the Acceptance Date (see
Section 3. Acceptance) of the Equipment (the "Payment Date"). You agree to
pay one prorate rent payment from the Acceptance Date to the first Payment
Date. You will pay all rent payments even if you do not receive a notice that
the payments are due. All rent payments and other amounts due will be made to
us at the address on this lease, or to any other address we designate in
writing.

         (B)  You will pay a late charge of five percent (5%) on any part of
a rent payment or other amount payable not made by you within five (5) days
of the due date, but only to the extent permitted by law.

         (C)  The rent payment on the Lease Schedule shall be raised or
lowered, in a proportionate manner, if there is an adjustment to the
equipment cost, or if a tax is required on the purchase of the Equipment or
the rent. We are authorized by you to insert the amount of the adjusted rent
on the appropriate Lease Schedule.

     3.  ACCEPTANCE.  On the date the Equipment is available for first use
(the "Acceptance Date"), you will sign and deliver to us an acceptance
certificate in a form satisfactory to us. We may terminate this lease without
cause for any Equipment you have not accepted within six (6) months of our
issuing a purchase order for the Equipment.

     4.  NET LEASE.  This is a net lease. You promise to pay when due all
taxes, licenses, fines, penalties, and other charges (including but not
limited to personal property, sales, state, Federal, and local taxes)
relating to this lease or the Equipment. Any taxes due will be based on the
full amount of the tax, regardless of any discounts we may receive.

     5.  END OF LEASE OPTION; REDELIVERY OF EQUIPMENT; LEASE EXTENSION.

         (A)  END OF LEASE OPTION.  Provided you are not in default, at the
expiration of the lease term of any Lease Schedule, you have the option to:
(i) renew this lease with respect to all the Equipment on that Lease Schedule
for a term agreeable to us and at a rent equal to the then fair market rental
for the renewal term, payable in advance, or (ii) purchase all, but not less
than all, of the Equipment provided on that Lease Schedule for the then fair
market value, or (iii) return the Equipment to us. You will give us ninety
(90) days prior written notice of the option you choose.

         (B)  REDELIVERY OF EQUIPMENT.  If you decide not to renew or
purchase all the Equipment, then when the term of that Lease Schedule
expires, at your own risk and expense, you will disconnect, properly package
for transportation, and return the Equipment to us, freight prepaid, to a
location designated by us within the continental United States. You agree to
include all
<PAGE>

instruction and service manuals, software documentation, service records, and
a certificate from the manufacturer of the Equipment or other service
organization reasonably acceptable to us that (i) at the time of shipment to
us, the Equipment is in good condition and contains all software and (ii) the
manufacturer will provide an extended maintenance contract to a new user at a
new location to perform the same or similar procedures as performed by you,
without additional costs for repair, refurbishment or software.

         (C)  LEASE EXTENSION.  If you do not renew, purchase or return the
Equipment as provided above, then this lease shall be extended on a
month-to-month basis for a minimum of six (6) months and you agree to pay us
the same rent as stated on the Lease Schedule. During the month-to-month
period, at our option, we may terminate this lease at any time by giving you
ten (10) days notice.

     6.  OWNERSHIP; IDENTIFICATION.  We are the owner of the Equipment and
have title to the Equipment. If any other person attempts to claim ownership
of the Equipment by asserting that claim against you or through you, you
agree, at your expense, to protect and defend our title to the Equipment.
Further, you agree that you will at all times, and at your expense, keep the
Equipment free from any legal process or lien, and you will give us immediate
notice if any legal process or lien is asserted or made against the
Equipment. So long as you are not in default under any of the terms of this
lease, we agree that you shall quietly use and enjoy the Equipment. We may
require plates or markings be placed on the Equipment indicating our
ownership. You represent that the Equipment shall always remain personal
property, even though the Equipment may become attached to real estate.

     7.  COMPLIANCE WITH LAW; INDEMNIFICATION.  You will use the Equipment
for business purposes only in compliance with all applicable laws and
regulations. You agree that we are not responsible for any injuries or losses
to you or any other person caused by the installation or use of the
Equipment. EXCEPT FOR ACTS BY US THAT ARE IN VIOLATION OF OUR OBLIGATIONS
UNDER THIS LEASE, YOU AGREE TO INDEMNIFY, HOLD HARMLESS AND DEFEND US FROM
AND AGAINST ANY AND ALL CLAIMS, COSTS, ATTORNEYS' FEES, EXPENSES, DAMAGES
AND LIABILITIES ARISING FROM OR RELATING TO THE POSSESSION, OPERATION, USE,
OWNERSHIP, SELECTION, LEASING, MAINTENANCE, DELIVERY OR RETURN OF ANY OF THE
EQUIPMENT.

     You agree that we shall be entitled to deductions and other benefits
provided to an owner of property by federal and state income tax laws,
including deductions for cost recovery and depreciation on the Equipment over
the shortest period available. If we lose the right to claim any benefits, or
any portion of the benefits are disallowed or recaptured as a result of any
omissions, acts, or failures to act by you, you shall pay us an amount, after
deduction of any taxes we must pay on said amount, that allows us to receive
(on an after-tax basis over the full term of the lease) the same rate of
return had there not been a loss or disallowance of benefits. You agree to
pay any interest or penalties due in connection with such loss or
disallowance.

     The indemnities in this section shall continue even after the term of
the lease has expired.

     8.  MAINTENANCE.  You agree that at your expense you will provide for
all maintenance, service, and repairs necessary to keep all Equipment in good
condition, working order and repair so that it meets or exceeds the
manufacturer's original performance specifications. You may not alter or
modify the Equipment without our prior written permission, which we will not
unreasonably withhold. You agree that all parts, modifications, alterations,
and additions are part of the Equipment and become our property.

     9.  DISCLAIMER OF WARRANTIES; LIMITATION OF LIABILITY.  WE ARE LEASING
THE EQUIPMENT TO YOU "AS IS". WE MAKE NO WARRANTIES, EXPRESS OR IMPLIED,
INCLUDING WARRANTIES OF MERCHANTABILITY, NONINFRINGEMENT AND FITNESS FOR A
PARTICULAR PURPOSE OR ORDINARY USE IN CONNECTION WITH THIS LEASE. If the
seller or anyone else has made a representation or warranty to you as to the
Equipment or any other matter, you agree that such representation or warranty
shall not obligate us, nor shall the breach of such relieve you of, or in any
way affect, any of your obligations to us any this lease. If the Equipment is
not satisfactory for any reason, you shall make your claim only against the
seller and you shall nevertheless pay us all rent payable under this lease.
So long as you are not in default under any of the terms of this lease, we
transfer to you any warranties made to us by the manufacturer or seller. You
understand and agree that the seller, its agents and employees are not agents
of ours, nor are they authorized to waive or change any term or condition of
this lease. YOU AGREE, THAT REGARDLESS OF CAUSE, YOU WILL NOT ASSERT ANY
CLAIM WHATSOEVER AGAINST US FOR LOSS OF PROFITS YOU EXPECTED TO MAKE OR ANY
OTHER DIRECT, SPECIAL, OR INDIRECT DAMAGES.

     10. ASSIGNMENT. YOU MAY NOT SELL, TRANSFER, ASSIGN, OR SUBLEASE THE
EQUIPMENT. WE MAY, WITHOUT NOTIFYING YOU, SELL, ASSIGN OR TRANSFER THIS LEASE
AND OWNERSHIP OF THE EQUIPMENT; AND YOU AGREE THAT IF WE DO SO, THE NEW LESSOR
WILL HAVE THE SAME RIGHTS AND BENEFITS THAT WE NOW HAVE, AND THE NEW LESSOR
WILL NOT HAVE TO PERFORM ANY OF OUR OBLIGATIONS. YOU AGREE THAT THE RIGHTS OF
THE NEW LESSOR WILL NOT BE SUBJECT TO ANY CLAIMS, DEFENSES OR SET-OFFS THAT
YOU MAY HAVE AGAINST US. HOWEVER, ANY SUCH ASSIGNMENT, SALE, OR TRANSFER OF
THIS LEASE OR THE EQUIPMENT WILL NOT RELIEVE US OF OUR

<PAGE>

OBLIGATIONS TO YOU UNDER THIS LEASE. YOU AGREE TO PAY ALL RENT PAYMENTS AND
OTHER AMOUNTS DUE DIRECTLY TO OUR ASSIGNEE IF WE NOTIFY YOU TO DO SO.

     11. INSURANCE; LOSS OR DAMAGE.

          (A) INSURANCE. You agree to maintain liability insurance and keep
the Equipment fully insured against loss until you have met all of your
obligations under this Lease. You agree to provide and maintain, at your
expense, insurance against fire, theft, and all other risks of loss
customarily insured against on the Equipment by businesses like yours, for
the greater of the full replacement value or the Stipulated Loss Value
reflected on the attached Exhibit A. Prior to the Equipment being delivered
to you, you agree to provide us with certificates or other evidence of
insurance in a form acceptable to us, from insurers acceptable to us, that
name us as additional insured for liability insurance and loss payee for
property damage insurance, and provide us with at least thirty (30) days
prior written notice if the policy is changed or canceled.

          (B) LOSS OR DAMAGE. You will bear the entire risk of loss and
damage from any cause whatsoever ("Loss"). If a Loss occurs, you shall
promptly notify us and, at our option, either (i) place the Equipment in good
condition and repair; or (ii) replace the Equipment with equipment having the
same value and function which is acceptable to us; or (iii) pay us the fair
value of the Equipment on the date of the Loss, which you agree will be the
sum of (a) the total rent due and owing at the time of such payment, and (b)
the amount arrived at by multiplying the equipment cost by the Stipulated
Loss Value opposite the rent payment number preceding the date of Loss.

     12. USE; LOCATION.

          (A) USE. You shall cause the Equipment to be operated by qualified
personnel only, within its normal capacity, and in accordance with applicable
manufacturers' instructions and governmental regulations. YOU AND YOUR AGENTS
AND EMPLOYEES ASSUME RESPONSIBILITY FOR ANY CLAIMS OR DAMAGES ARISING FROM
SUCH USE. You are responsible for all licenses, permits and consents required
by law or any government body in connection with the Equipment.

          (B) LOCATION. You agree that you will not remove the Equipment from
its place of installation unless you get our written permission in advance.

     13. EVENT OF DEFAULT. You will be default if you (a) do not pay rent or
any other amount payable within ten (10) days of the due date; or (b) break
any of your promises or fail to perform any obligation under this lease and

payments due under this lease, present valued using a six percent (6%) per
year discount rate; (b) require you to pay us one hundred twenty five percent
(125%) of the then applicable Stipulated Loss Value as liquidated damages;
(c) remove the Equipment from its location; (d) sell or lease any or all of

warrant that: (a) you are in good standing under the laws of the jurisdiction

                         MOBILE PET SYSTEMS, INC. (LESSEE)


              This Addendum I (this "Addendum") is attached to and hereby
made an integral part of that certain Equipment Lease No. 4125 between the
above-referenced Lessor and Lessee (herein, the "Lease"). This Addendum
affects the Lease and each Lease Schedule attached thereto, and in that
context is distinguished from those certain addenda which are now or may
hereafter be attached to the Lease and which reference themselves as addenda
to a specific Lease Schedule (e.g., those certain Addenda attached to Lease
Schedule No. 4125.01). Terms used herein with initial capital letters, to the
extent not otherwise defined herein, shall have the meanings given such terms
in the Lease.

              1.     CONDITIONS PRECEDENT.  Lessor and Lessee intend that the
Lease shall govern the rights and duties of the parties with respect to a number
of different items of Equipment, each of which shall be identified and
referenced on a separate Lease Schedule. With respect to all such Equipment
other than the Equipment described on Lease Schedule No. 4125.01, the following
conditions precedent must be satisfied prior to the addition of any such
Equipment to the terms of the Lease:

                     (a)    There shall not exist any event of default under the
       Lease, or any act or occurrence which, with the giving of notice or the
       passage of time, or both, would constitute an event of default;

                     (b)    Lessee shall have demonstrated, to Lessor's
       satisfaction, that Lessee possesses cash in an amount equal to twenty
       percent (20%) of the total purchase price applicable to the proposed new
       Equipment, which amount shall have been placed by Lessee in a separate
       operating account, for use as working capital with respect to the
       operations of the proposed new items of Equipment;

                     (c)    Lessee shall have provided to Lessor documentation
       substantiating that, with respect to the specific proposed new items of
       Equipment, Lessee has in effect signed, valid and enforceable contractual
       agreements (each of which must be in form and substance satisfactory to
       Lessor) with one or more hospitals (the creditworthiness of which must be
       satisfactory to Lessor in all respects), which agreements will provide
       Lessee with a minimum of eighty-eight (88) positron emission tomography
       ("PET") procedures per month, for a term that shall not expire prior to
       the date final payment is due under the Lease with respect to the
       proposed new items of Equipment. Lessor shall be entitled to perform its
       own due diligence

<PAGE>

       with respect to each hospital which is to become party to any such
       contract, to determine whether such hospital is satisfactorily
       creditworthy, in Lessor's sole discretion;

                     (d)    Lessee shall have demonstrated, to Lessor's
       satisfaction, that Lessee has received not less than $1,800,000 as the
       net proceeds from Lessee's pending offering of securities. In addition to
       the foregoing, Lessor shall have reviewed and approved all terms and
       conditions applicable to such offering of securities, together with the
       rights and privileges to be granted in favor of all persons purchasing
       securities issued by Lessee;

                     (e)    Lessee shall have executed and delivered a
       Collateral Assignment of Agreements, or a supplement to any previously
       delivered Collateral Assignment of Agreements, either of which must be in
       form and substance satisfactory to Lessor, pursuant to which Lessee shall
       have collaterally assigned in favor of Lessor all of its rights under
       those certain agreements referenced in Section 1(c) above;

                     (f)    All documents and instruments previously executed in
       favor of Lessor, including without limitation that certain Continuing
       Personal Guaranty with respect to which Paul J. Crowe is "Guarantor," and
       that certain Subordination Agreement with respect to which Paul J. Crowe,
       John Fleming, and Brent Nelson are "Directors," shall each remain in full
       force and effect, and none of the parties to any such agreement shall
       have revoked, rescinded, or in any way attempted to repudiate their
       obligations to Lessor thereunder; and

                     (g)    Lessee shall have deposited with Lessor, as a
       security deposit to be held by Lessor and in Lessor's name, an amount
       equal to three (3) months rental payment under the Lease Schedule which
       will be applicable to the proposed new Equipment. The foregoing deposit
       may be applied by Lessor in Lessor's discretion upon the occurrence of
       any event of default under the Lease. If not previously applied, the
       foregoing deposit shall be applied in payment of the last three rental
       payments accruing under the applicable Lease Schedule. Lessor shall not
       be obligated to segregate the foregoing deposit or to establish a
       separate account for the same. If requested by Lessor, Lessee shall
       provide Lessor with Lessee's taxpayer identification number and any other
       information necessary in order to permit Lessor to file reports for tax
       purposes.

                     (h)    In the event that Lessor's total committed funds
       under the Lease (determined by reference to the total progress payments
       funded by Lessor to the manufacturers and suppliers of all Equipment then
       subject to the Lease, together with other ancillary items and costs
       necessary in order to enable such Equipment to be installed and accepted
       by Lessee) is greater than $5,000,000, or after giving effect to the
       addition of such items of Equipment as are proposed to be subject to the
       next Lease Schedule, would exceed $5,000,000, then the following two
       additional conditions must be satisfied:


                                          2
<PAGE>

                            (i)    Lessee shall have demonstrated, to Lessor's
              satisfaction, that Lessee possesses a minimum balance of cash and
              cash equivalents of at least $500,000; and

                            (ii)   Lessee shall have attained a Debt Service
              Coverage Ratio (calculated in the manner set forth in Section 3
              below), of not less than 1.0:1.0, for the shorter of (x) the
              period from the Start Date (hereafter defined) of the Lease
              through the date of determination or (y) the period of twelve full
              calendar months most recently ended.

              2.     CONDITIONS PRECEDENT - LEASE SCHEDULE 4125.01.  With
respect to the Equipment described on Lease Schedule No. 4125.01, Lessor has
waived or modified the conditions precedent set forth in Sections 1(b), (c), and
(d). The requirements of Section 1(g) above were not applicable to the Equipment
described on Lease Schedule No. 4125.01. In consideration of these waivers and
modifications, Paul J. Crowe has provided to Lessor his Continuing Personal
Guaranty of even date herewith. Lessor agrees to release such Continuing
Personal Guaranty at such time as Lessee has provided to Lessor evidence that
contractual agreements sufficient to satisfy the requirements of Section 1(c)
above are in force. In addition, Lessor has reduced the requirement as set
forth in Section 1(d) above to require only that Lessee have received $1,100,000
in net proceeds from such securities offering.

              3.     DEBT SERVICE COVERAGE COVENANT.  The first day of the first
full calendar month following the month in which the last progress payment under
Lease Schedule No. 4125.01 is disbursed shall be referred to herein as the
"Start Date." Commencing with a test to be conducted for the twelve month period
beginning on the Start Date, and on a trailing twelve month basis for subsequent
tests to be conducted for the periods ending fifteen, eighteen, and twenty-one
months after the Start Date, Lessee shall maintain a ratio (the "Debt Service
Coverage Ratio") of Operating Cash Flow (hereafter defined) to Contractual Debt
Service (hereafter defined) of not less than 1.0:1.0. Commencing with the test
conducted for the trailing twelve months ending twenty-four months following the
Start Date, and continuing thereafter throughout the term of the Lease, Lessee
shall maintain a Debt Service Coverage Ratio of not less than 1.25:1.0. For
purposes of this section, the following definitions shall apply:

              "Operating Cash Flow" shall mean, for any period, Lessee's net
income or loss (excluding the effect of any extraordinary gains or losses)
determined in accordance with generally accepted accounting principles ("GAAP"),
PLUS each of the following items, to the extent deducted from the revenues of
Lessee in the calculation of net income or loss: (i) depreciation; (ii)
amortization and other non-cash charges; (iii) rent paid to Lessor in respect of
the Lease; (iv) without duplication of amounts described in the preceding clause
(iii), interest expense paid or accrued, including, without limitation, interest
imputed on leases which would, in accordance with GAAP, be classified as
"capital leases"; and (v) total federal and state income tax expense determined
as the accrued liability of Lessee in respect of such period, regardless of what
portion of such expense has actually been paid by Lessee during such period, and
AFTER DEDUCTION FOR each of


                                          3
<PAGE>

(a) federal and state income taxes, to the extent actually paid during such
period; (b) any non-cash income (but only to the extent such non-cash income was
included in the revenues of Lessee in the calculation of net income or loss);
and (c) all actual capital expenditures made by Lessee during such period and
not financed (with the qualification that all amounts expended by Lessee
pursuant to the Leases, if considered capital expenditures under GAAP, shall be
deemed financed for purposes of this definition). "Contractual Debt Service"
shall mean, for any period, the sum of payments made (or, as to clauses (i) and
(ii) of this sentence, required to be made) by Lessee during such period for (i)
scheduled payments of rent and any other amounts due under the Lease, (ii)
scheduled interest and principal payments due on any and all outstanding
indebtedness of Lessee, other than indebtedness described in the following
clause (iii), and (iii) interest and principal payments made on any indebtedness
of Lessee the repayment of which has been subordinated to the payment of
Lessee's obligations in respect of the Leases.

              4.     FINANCIAL REPORTING.  Lessee shall furnish to Lessor:
(i) within thirty (30) days after the end of each month, internally prepared
financial statements of Lessee, including at a minimum a balance sheet and
income statement for the year to date period, together with comparable
information for the prior year to date period, prepared in accordance with
generally accepted accounting principles ("GAAP"), and on a basis consistent
with such statements delivered to Lessor for prior periods; (ii) within
ninety (90) days after the end of each of Lessor's fiscal years, audited
financial statements for Lessor, prepared in accordance with GAAP applied on
a consistent basis, and accompanied by the unqualified report thereon of
independent certified public accountants acceptable to Lessor, together with
any management letters delivered by Lessee's accountants to its management;
(iii) within forty-five (45) days prior to the end of each fiscal year of
Lessee, annual operating budgets (including income statements, balance sheets
and cash flow statements, by month) for the upcoming fiscal year of
Lessee; and (iv) such other financial information and statements as Lessor
shall request from time to time regarding Lessee's business affairs,
financial condition, and the results of its operations.

              5.     PRICING.  Lessor shall be entitled to increase payments
accruing under any Lease Schedule if, and to the extent that, the rate offered
on a five-year United States Treasury Note increases over 4.65% (being the yield
that was available as of January 28, 1999). The rate offered on a five-year U.S.
Treasury Note shall be defined as the rate shown under the column heading "Ask
Yld." for "Govt. Bonds & Notes" in the "Treasury Bonds, Notes & Bills" Section
of THE WALL STREET JOURNAL - Western Edition published on the fifth business day
prior to the date of funding under a given Lease Schedule for the government
bond or note with a maturity date in the same month and year as the date the
final installment payment applicable to such Lease Schedule comes due (such date
being referred to herein as the "Schedule Maturity Date"), or, if there are more
than one government bonds or notes with a maturity date in the same month and
year as the Schedule Maturity Date, the highest of the rates shown in the "Ask
Yld." column for any such bond or note, or, if there is no government bond or
note with a maturity date in the same month and year as the Schedule Maturity
Date, the average (rounded to the next highest basis point) of the rates shown
in the "Ask Yld." column for the bonds or notes in the months preceding and
following the month in which the Schedule Maturity Date falls. In the event that
the foregoing information is no longer


                                          4
<PAGE>

published in THE WALL STREET JOURNAL, then the rate offered on a five-year
U.S. Treasury Note shall be defined as that annual rate of interest quoted in
Statistical Release H.15(519) published from time to time by the Board of
Governors of the Federal Reserve System as the yield for "5-year U.S.
Government Securities-Treasury Constant Maturities" for "This Week".

          The parties hereto have executed this Addendum I effective as of
the 8th day of April, 1999.

                     AND MOBILE PET SYSTEMS, INC. (LESSEE)

INTERIM RENT:

Notwithstanding anything to the contrary in the Lease, Lessor and Lessee
hereby agree that COMPUTERS UNLIMITED ("Seller") is providing Equipment under
the Lease and requires that advance monies be paid by Lessor prior to
delivery and acceptance by Lessee. The advance required by Seller is TWENTY
PERCENT (20%) of the purchase price to be paid by customer upon issuance of
the purchase order to Seller; Fifty Percent (50%) of the purchase price upon
the completion, and THIRTY PERCENT (30%) of the purchase price plus
applicable sales tax upon Lessor's receipt of Lessee's written acceptance of
the Equipment.

To compensate Lessor for performing as described above, Lessee agrees to pay
Lessor rental(s), monthly in arrears, computed at two percent (2%) over the
prime rate as quoted in the Wall Street Journal, which rate shall be adjusted
accordingly as such prime rate changes from time to time during the term of
this Interim Rent Agreement, from the day said advance monies are paid by
Lessor for the actual number of days such advances are outstanding ("Interim
Rent").

The Interim Rent chargeable to the Lessee shall terminate upon Lessor's
receipt of Lessee's written acceptance of the equipment for the purpose of
the Lease and the commencement of the basic lease term, in accordance with
the terms of the Lease, at which time the full lease rental under the Lease
("Basic Rental") will commence.

The monies advanced by Lessor to Seller as aforesaid are in any and all events
an obligation of Lessee. Lessee agrees to promptly reimburse Lessor in the
event, and for any reason whatsoever, Lessee does not accept the Equipment. In
addition, Lessee agrees to hold Lessor harmless from any and all claims by
the Seller arising out of Lessee's failure or refusal to accept the Equipment.

The undersigned agree to all the terms and conditions set forth above and IN
WITNESS WHEREOF, Lessor and Lessee hereby execute this Addendum this ____ day
of ______________, 19___.

                                  SECURITY AGREEMENT

              SECURITY AGREEMENT dated effective as of April 8, 1999, by and
between MOBILE PET SYSTEMS, INC., a Delaware corporation ("Lessee") and FINOVA
CAPITAL CORPORATION, a Delaware corporation ("Lessor"), executed pursuant to
that certain Equipment Lease No. 4125 between Lessee and Lessor, as the same may
be supplemented from time to time by the addition of Lease Schedules referencing
further items of equipment which shall become subject thereto (as so
supplemented, the "Lease").

              1.     DEFINITIONS.  All terms used herein which are defined in
the Arizona Uniform Commercial Code (the "Code") shall have the same meanings
herein as in the Code unless the context in which such terms are used herein
indicates otherwise.  All capitalized terms defined in the Lease and which are
used as defined terms in this Security Agreement, unless otherwise defined
herein, shall have the meanings ascribed to them in the Lease, the applicable
provisions of which are incorporated herein.

              2.     SECURITY INTEREST.  To secure the performance and payment
of all obligations of Lessee pursuant to the Lease (collectively, the "Lessee's
Obligations"), Lessee hereby grants to Lessor a security interest in all of
Lessee's right, title and interest in the property and property rights more
fully described on EXHIBIT A attached hereto and incorporated herein by
reference (collectively, the "Collateral").  Such security interests shall be
superior and prior to all other liens.

              3.     REPRESENTATIONS, WARRANTIES AND COVENANTS.  Lessee hereby
represents, warrants and covenants to Lessor as follows:

                     3.1    Lessee is the owner of the Collateral, except the
       portion thereof consisting of after-acquired property, and Lessee will be
       the owner of such after-acquired property, free from any lien except the
       lien created hereby in favor of Lessor.

                     3.2    There is listed in EXHIBIT B attached hereto the
       location of the chief place of business of Lessee and, if different, the
       location(s) where any Tangible Collateral (as hereafter defined) and the
       books and records of Lessee are kept.  Lessee shall not (a) change any
       such locations(s), (b) open any new places of business, (c) change its
       corporate name, or (d) conduct a business under any other names or use
       any trade names or fictitious names, other than its own corporate name,
       without, in each case, giving to Lessor


<PAGE>

       thirty days' prior written notice of any such change.  "Tangible
       Collateral" consists of all items which would be considered "goods,"
       "equipment," "inventory" or "fixtures" under the Code.

                     3.3    Lessee will at all times keep the Tangible
       Collateral in good operating condition and repair, operate and maintain
       the same in compliance with all laws and insurance policies applicable
       thereto, and pay promptly when due all taxes, insurance premiums and
       other governmental charges upon or relating to any of the property,
       income or receipts of Lessee.

              4.     INSURANCE.  Lessee shall maintain such insurance, written
by such insurers and in such amounts and on such forms as are satisfactory to
Lessor.  The net proceeds collected by Lessor, after deducting all costs and
expenses (including attorneys' fees) of collection shall be applied, at Lessor's
option, either toward replacing or restoring the Collateral, in a manner and on
terms satisfactory to Lessor, or to the payment of Lessee's obligations.  Any
proceeds applied to the payment of Lessee's Obligations shall be applied in such
manner as Lessor may elect.  In no event shall such application relieve Lessee
from payment in full of all installments of rent coming due under the Lease.

              5.     PROTECTION OF COLLATERAL.  In the event of the failure of
Lessee to (a) maintain in force and pay for any insurance which Lessee is
required to provide pursuant to this Security Agreement or the Lease, (b) keep
the Tangible Collateral in good repair and operating condition, (c) keep the
Collateral free from any other liens, and (d) pay when due all taxes, levies and
assessments on or in respect of the Collateral, Lessor, at its option, may (but
shall not be required to) procure and pay for such insurance, place the Tangible
Collateral in good repair and operating condition, or otherwise make good any
other aforesaid failure of Lessee and all sums advanced by Lessor, with interest
thereon at the rate of fourteen percent (14%) per annum, shall be part of
Lessee's Obligations, payable on demand.

              6.     FINANCING STATEMENTS; FURTHER ASSURANCES.  Lessee,
concurrently with the execution of this Security Agreement, and from time to
time thereafter as requested by Lessor, shall execute and deliver to Lessor such
financing statements, continuation statements, amendments to financing
statements and other documents, in form satisfactory to Lessor, as Lessor may
require to perfect and continue in effect the lien of Lessor.  Lessee
irrevocably appoints Lessor its attorney-in-fact, in the name of Lessee or
Lessor, to execute and file from time to time any such financing statements,
continuation statements and amendments thereto, which appointment shall be
deemed to be a power coupled with an interest.

              7.     EVENTS OF DEFAULT.  Lessee shall be in default under this
Security Agreement upon the occurrence of (i) any failure of Lessee to perform
its

                                       2

<PAGE>

obligations hereunder or (ii) any default under the Lease (collectively herein,
an "Event of Default").

              8.     REMEDIES UPON DEFAULT.  Upon the occurrence of an Event of
Default, Lessor shall have all the rights and remedies of a secured party under
the Arizona Uniform Commercial Code and all other rights and remedies accorded
to a secured party in equity or law.  Upon the request of Lessor, Lessee shall
assemble and make the Tangible Collateral available to Lessor at a place
reasonably convenient to Lessor.  Any notice of sale or other disposition of the
Collateral given not less than ten (10) days prior to such proposed action shall
constitute reasonable and fair notice of such action.  Lessee shall be liable
for any deficiency.  Lessee expressly waives any right to have the Collateral
marshalled on any foreclosure, sale or other enforcement hereof.

              9.     NOTICES.  All notices and communications under this
Security Agreement shall be given in accordance with the Lease.

              10.    SUCCESSORS AND ASSIGNS.  This Security Agreement shall be
binding upon and inure to the benefit of and be enforceable by the respective
successors and assigns of Lessor and Lessee.

              11.    APPLICABLE LAW.  THIS SECURITY AGREEMENT SHALL BE GOVERNED
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF ARIZONA, EXCEPT TO THE
EXTENT THAT APPLICABLE LAW REQUIRES THAT THE LAWS OF ANOTHER JURISDICTION GOVERN
THE PERFECTION AND ENFORCEMENT OF THE SECURITY INTERESTS GRANTED TO LESSOR.

              12.    TERMINATION.  This Security Agreement shall terminate upon
the payment in full of Lessee's Obligations.

              13.    COUNTERPARTS; FACSIMILE EXECUTION.  This Security Agreement
may be executed in any number of separate counterparts, all of which, when taken
together, shall constitute one and the same instrument, admissible into
evidence, notwithstanding the fact that all parties did not sign the same
counterpart.  Delivery of an executed counterpart of this Security Agreement by
telefacsimile shall be equally as effective as delivery of a manually executed
counterpart of this Security Agreement.  Any party delivering an executed
counterpart of this Security Agreement by telefacsimile shall also deliver a
manually executed counterpart of this Security Agreement, but the failure to
deliver a manually executed counterpart shall not affect the validity,
enforceability, and binding effect of this Security Agreement.

NEITHER THIS WARRANT NOR THE STOCK FOR WHICH IT MAY BE EXERCISED HAS BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED ("SECURITIES ACT"),
OR ANY OTHER FEDERAL OR STATE SECURITIES LAW, AND MAY NOT BE SOLD, TRANSFERRED
OR OTHERWISE DISPOSED OF, EXCEPT AS PROVIDED IN ARTICLE III, UNLESS SO

                           MOBILE PET SYSTEMS, INC.

                        COMMON STOCK PURCHASE WARRANT

        This certifies that, for value received, FINOVA CAPITAL CORPORATION,
a Delaware corporation, and any registered assignee ("Holder"), is entitled
to subscribe for and purchase from Mobile PET Systems, Inc. ("Company"), a
corporation organized and existing under the laws of the State of Delaware,
One Hundred Eighty Thousand (180,000) shares (subject to adjustment as set
forth in Article II below, "Warrant Shares") of Common Stock of the Company,
par value $.01 per share ("Common Stock"), at an Exercise Price per share as
defined below in Section 1.02 (subject to adjustment as set forth in Article
II below), at any time and from time to time beginning on the date hereof
("Original Issue Date"), and ending on March __, 2004 ("Expiration Date"),
upon written notice from the Holder to the Company ("Notice") and subject to
the terms provided herein.

        Capitalized terms used herein, and not otherwise defined, shall have
the meanings specified in Article V. This Warrant is subject to the following
provisions, terms and conditions:

                                  ARTICLE I.

                        EXERCISE; RESERVATION OF SHARES

Section 1.01  WARRANT EXERCISE. The rights represented by this Warrant may be
exercised by the Holder at any time and from time to time prior to the
Expiration Date, upon Notice, by the surrender at the principal office of the
Company of this Warrant together with a duly executed subscription in the
form annexed ("Subscription Form") and accompanied by payment, in certified
or immediately available funds, of the Exercise Price for the number of
Warrant Shares specified in the Subscription Form. The shares so purchased
shall be deemed to be issued to the Holder (unless contrary instructions are
provided on the Subscription Form) as the record owner of such shares as of
the close of business on the date on which this Warrant shall be exercised as
hereinabove provided. No fractional shares or script representing fractional
shares shall be issued upon the exercise of this Warrant, but the Company
shall pay the Holder an amount equal to the Market Value of such fractional
share of Common Stock in lieu of each fraction of a share otherwise called
for upon any exercise of this Warrant.


<PAGE>

        Section 1.02  EXERCISE PRICE. "Exercise Price" shall mean a price per
share equal to the lesser of (a) $2.50 per share or (b) the average of the
last reported sale prices of the Common Stock for the five (5) trading days
immediately preceding the Original Issue Date as shown by the principal
national securities exchange or quotation system on which the Common Stock is
then listed for trading.

        Section 1.03  ALTERNATE METHOD OF PAYMENT. In addition to the method
of payment set forth in Section 1.01 above and in lieu of a cash payment
required thereunder, the Holder shall have the right to exercise the Warrant
in full or in part by surrendering this Warrant in the manner specified
herein above in exchange for the number of Warrant Shares equal to the
product of (a) the number of shares as to which the Warrant is being
exercised multiplied by (b) a fraction, the numerator of which is the Market
Value of the Common Stock less the Exercise Price, and the denominator of
which is Market Value.

        Section 1.04  CERTIFICATES. Certificates for the shares purchased
pursuant to Section 1.01 shall be delivered to the Holder within a reasonable
time, not exceeding ten (10) business days, after the rights represented by
this Warrant shall have been so exercised, and a new Warrant in the name of
the Holder representing the rights, if any, that shall not have been
exercised prior to the Expiration Date with respect to this Warrant shall
also be delivered to such Holder within such time, with such new Warrant to
be identical in all other respects to this Warrant. The term "Warrant," as
used herein, includes any Warrants into which this Warrant may be divided or
combined and any subsequent Warrants issued upon the transfer or exchange or
reissuance upon loss hereof. Upon receipt by the Company of this Warrant,
together with the Exercise Price, if any, at its office, or by the stock
transfer agent of the Company, if any, at its office, in proper form for
exercise in accordance with the terms hereof, the Holder shall be deemed to
be the holder of record of the shares of Common Stock issuable upon such
exercise, notwithstanding that the stock transfer books of the Company shall
then be closed or that certificates representing such shares of Common Stock
shall not then be actually delivered to the Holder. The Company shall pay
any and all documentary stamp or similar issue or transfer taxes payable in
respect of the issue or delivery of shares of Common Stock on exercise of
this Warrant.

        Section 1.05  RESERVATION OF SHARES. The Company represents,
warrants, covenants and agrees:

                (a)   That all shares of Common Stock that may be issued upon
        exercise of this Warrant will, upon issuance, be validly issued,
        fully paid and nonassessable and free from all taxes, liens and
        charges with respect to the issue thereof;

                (b)   That during the period the rights represented by this
        Warrant may be exercised, the Company will at all times have
        authorized, and reserved for the purpose of issue and delivery upon
        exercise of the rights evidenced by this Warrant, a sufficient number
        of shares of Common Stock to provide for the exercise of the rights
        represented by this Warrant; and


                                       2

<PAGE>

                (c)   If the Common Stock is listed on any national
        securities exchange or similar trading market, the shares of Common
        Stock that may be issued upon exercise of this Warrant will, prior
        to or on the date that a registration statement covering the Warrant
        Shares is effective, also be listed on such exchange subject to
        notice of issuance.

                                  ARTICLE II.

                                  ADJUSTMENTS

        Section 2.01  REORGANIZATION, RECLASSIFICATION, CONSOLIDATION, MERGER
OR SALE.

                (a)   CAPITAL EVENTS. If any reorganization or
        reclassification of the capital stock of the Company, or any
        consolidation or merger of the Company with another corporation, or
        the sale of all or substantially all of its assets to another
        corporation (in any instance, a "Capital Event") shall be effected in
        such a way that holders of Common Stock shall be entitled to receive
        stock, securities or assets (including cash) with respect to or in
        exchange for their Common Stock, then, as a condition of such Capital
        Event, lawful and adequate provisions shall be made whereby the
        Holder hereof shall thereafter have the right to purchase and receive
        upon the basis and upon the terms and conditions specified in this
        Warrant and in lieu of the shares of the Common Stock of the Company
        immediately theretofore purchasable and receivable upon the exercise
        of the rights represented hereby, an amount of such shares of stock,
        securities or assets (including cash) as may have been issued or payable
        with respect to or in exchange for a number of outstanding shares of
        such Common Stock equal to the number of shares of such stock
        immediately theretofore purchasable and receivable upon the exercise
        of the rights represented hereby had such Capital Event not taken
        place.

                (b)   PRESERVATION OF VALUE. In the case of any Capital
        Event, appropriate provision shall be made with respect to the rights
        and interests of the Holder of this Warrant to the end that the
        provisions hereof (including, without limitation, provisions for
        adjustment of the number of shares that may be issued upon exercise
        of this Warrant and the Exercise Price hereof) shall thereafter be
        applicable, as nearly as may be, in relation to any shares of stock,
        securities or assets (including cash) thereafter deliverable upon the
        exercise of the rights represented hereby.

                (c)   OBLIGATION EXPRESSLY ASSUMED. The Company shall not
        effect any consolidation, merger or sale of all or substantially all
        of its assets, unless prior to the consummation thereof the successor
        corporation (if other than the Company) resulting from such
        consolidation or merger, or the corporation into or for the
        securities of which the previously outstanding stock of the Company
        shall be changed in connection with such consolidation or merger, or
        the corporation purchasing such assets, as the case may be, shall
        assume by written instrument executed and mailed or delivered to the
        registered Holder at the last address of such Holder appearing on
        the books of the Company, the obligation to deliver to such Holder,
        upon exercise of this Warrant, such shares of stock,


                                       3

<PAGE>

        securities or assets (including cash) as, in accordance with the
        foregoing provisions, such Holder may be entitled to purchase.

        Section 2.02  SUBDIVISION OR COMBINATION OF STOCK. In the event that
the Company shall at any time subdivide or split its outstanding shares of
Common Stock into a greater number of shares, the number of Warrant Shares
subject to issuance upon exercise of this Warrant at the opening of business
on the day upon which such subdivision becomes effective shall be
proportionately increased. In the event that the outstanding shares of Common
Stock of the Company shall be combined into a smaller number of shares, the
number of shares subject to issuance upon exercise of this Warrant at the
opening of business on the day upon which such subdivision becomes effective
shall be proportionately decreased. Any such increase or decrease, as the
case may be, shall become effective immediately after the opening of business
on the day following the day upon which such subdivision or combination, as
the case may be, becomes effective.

        Section 2.03  STOCK DIVIDENDS. In the event that the Company shall at
any time declare any dividend or distribution upon its Common Stock payable
in stock, the number of Warrant Shares subject to issuance upon exercise of
this Warrant shall be increased by the number (and the kind) of shares which
would have been issued to the holder of this Warrant if this Warrant were
exercised immediately prior to such dividend. Such increase shall become
effective immediately after the opening of business on the day following the
record date for such dividend or distribution.

        Section 2.04  CASH OR OTHER NON-STOCK DIVIDENDS. In the event that
the Company shall at any time declare any dividend or distribution upon its
Common Stock payable in cash, assets or other property, (a "Non-Stock
Dividend") the number of Warrant Shares subject to issuance upon the exercise
of this Warrant shall be increased to a number obtained by multiplying (a)
the number of Warrant Shares for which this Warrant is exercisable
immediately prior to such dividend by (b) a fraction (i) the numerator of
which shall be the Market Value per share of Common Stock at the date of the
taking of the record holders of Common Stock entitled to such dividend or
distribution and (ii) the denominator of which shall be such Market Value per
share of Common Stock minus the Non-Stock Dividend paid per one share of
Common Stock as determined for purposes of accounting for such transaction on
the books of the Company. Such increase shall become effective immediately
after the opening of business on the day following the record date for such
dividend or distribution.

        Section 2.05  ADDITIONAL COMMON STOCK, OPTIONS, CONVERTIBLE SECURITIES.
In the event the Company shall (a) issue any additional shares of Common
Stock (other than through a stock subdivision or split covered by Section
2.02 or a dividend upon the Company's Common Stock payable in stock covered
by Section 2.03) for a consideration (but in no event shall said
consideration be rendered except in cash) per share less than the Market Value
thereof, (b) grant any options or warrants for the purchase of Common Stock
where the Price per Share (as hereinafter defined) of Common Stock issuable
upon conversion, exchange or exercise is less than the Market Value thereof
immediately prior to the time of issuance or grant thereof ("Options"), or
(c) issue or sell any convertible securities that are convertible into or


                                       4


<PAGE>

exchangeable for Common Stock at a Price per Share less than the Market Value
thereof immediately prior to the time of issuance or grant thereof
("Convertible Securities"), the number of Warrant Shares subject to issuance
upon exercise of this Warrant shall be increased to a number obtained by
multiplying (i) the number of Warrant Shares for which this Warrant is
exercisable immediately prior to such issuance, grant or sale by (ii) a
fraction (A) the numerator of which shall be the sum of the Outstanding
Section 2.05 Shares (as defined below) plus the Deemed Additional Shares
resulting from such issuance, grant, sale or payment and (B) the denominator
of which shall be the number of shares ("Outstanding Section 2.05 Shares") of
Common Stock exercisable or outstanding immediately prior to such issuance,
grant, sale or payment (as if all Options, warrants and rights to convert or
exchange Convertible Securities outstanding immediately prior to such
issuance, grant or sale had been exercised, whether or not actually
exercisable on such date). Such increase shall become effective immediately
after the opening of business on the day following such issuance, grant or
sale, as the case may be.

       Section 2.06  PHANTOM STOCK AND SIMILAR COMPENSATION PLANS.  In the
event the Company pays compensation to any employees, consultants or any
other person pursuant to any phantom stock option, stock appreciation right,
or other similar plan whereby the compensation paid is triggered by the
settlement of a right (the "Right") to receive the difference between (i) a
pre-established price per Share that is less than the Market Value of the
Common Stock immediately prior to the time of issuance or grant of the Right
and (ii) the Market Value per share of the Common Stock on the settlement
date of the Right, the number of Warrant Shares subject to issuance upon
exercise of this Warrant shall be increased to a number obtained by
multiplying (a) the number of Warrant Shares for which this Warrant is
exercisable immediately prior to the date such compensation is paid by (b) a
fraction (i) the numerator of which shall be the exercise price per share of
Common Stock on the date of grant and (ii) the denominator of which shall be
the exercise price per share of Common Stock on the date of grant minus the
amount of compensation paid allocable to one share of Common Stock. Such
increase shall become effective immediately after the opening of business on
the day following such grant.

       Section 2.07  EQUITABLE ADJUSTMENT.  In the event the Company shall
participate in any extraordinary corporate event or transaction not otherwise
provided for herein, including a so-called issuer self-tender, there shall be
made an equitable and proportionate adjustment in the number of shares
issuable upon exercise of this Warrant and the Exercise Price consistent with
the principles of other such adjustments provided for in this Article II.

       Section 2.08  TREASURY SHARES.  The number of shares of Common Stock
outstanding at any given time shall not include shares owned or held by or
for the account of the Company or any subsidiary of the Company and the
disposition of any such shares shall be considered an issue or sale of Common
Stock for purposes of this Article II.

       Section 2.09  ADJUSTMENT OF EXERCISE PRICE.  Whenever the number of
shares of Common Stock that may be issued upon exercise of this Warrant is
adjusted and effective at the time such adjustment is effective, as provided
in Sections 2.01, 2.02 and 2.03 of this Article II, the Exercise Price shall
be adjusted (to the nearest whole cent) by multiplying each such Exercise
Price immediately prior to such adjustment by a fraction (x) the numerator of
which shall be the


                                       5

<PAGE>

number of shares of Common Stock which may be issued upon the exercise of
each such Warrant immediately prior to such adjustment, and (y) the
denominator of which shall be the number of shares of Common Stock so
purchasable immediately thereafter.  The Company may retain a firm of
independent certified public accountants (which may not be the regular
accountants employed by the Company) to make any required computation, and a
certificate signed by such firm shall be conclusive evidence of the
correctness of such adjustment.

       Section 2.10  COMMON STOCK BUY BACK.  In the event the Company shall
commence a buy back program for the acquisition by the Company of Common
Stock, the Company agrees to purchase at Market Value all Warrant Shares from
the Holder, if the Holder so desires.

       Section 2.11  RECORD DATE.  In the event that the Company shall not
take a record of the holders of its Common Stock for the purpose of entitling
them to receive a dividend payable in Common Stock, then such record date
shall be deemed for the purposes of this Article II to be the date of the
issue or sale of the shares of Common Stock deemed to have been issued or
sold upon the declaration of such dividend.

       Section 2.12  OFFICER'S CERTIFICATE.  Whenever the Exercise Price
shall be adjusted as provided in this Article II, the Company shall forthwith
file with its Secretary and retain in the permanent records of the Company,
an officer's certificate showing the adjusted Exercise Price determined as
provided in this Article II, setting forth in reasonable detail the facts
requiring such adjustment, including a statement of the number of additional
or fewer shares of Common Stock, and such other facts as may be reasonably
necessary to show the reason for and the method of computing such adjustment.
 Each such officer's certificate shall be made available at all reasonable
times for inspection by the Holder.

       Section 2.13  NOTICE OF ADJUSTMENT.  Upon any adjustment of the number
of shares that may be issued upon exercise of this Warrant or the Exercise
Price, the Company shall give notice thereof to the Holder, which notice
shall state the increase or decrease, if any, in the number of shares that
may be issued upon the exercise of this Warrant and the Exercise Price,
setting forth in reasonable detail the method of calculation and the facts
upon which such calculation is based.

       Section 2.14  DEFINITION OF "COMMON STOCK".  As used in this Article
II, the term "Common Stock" shall mean and include all of the Company's
authorized Common Stock of any class as constituted on the effective date
hereof, and shall also include any capital stock of any class of the Company
thereafter authorized that shall not be limited to a fixed sum or stated
value in respect of the rights of the holders thereof to participate in
dividends or the distribution of assets upon the voluntary or involuntary
liquidation, dissolution or winding up of the Company.

                                  ARTICLE III.

                  TRANSFER RESTRICTIONS; REGISTRATION RIGHTS

       Section 3.01  SECURITIES LAW TRANSFER RESTRICTIONS.  By taking and
holding this Warrant, the Holder (i) acknowledges that neither this Warrant
nor any shares of Common Stock that may be issued upon exercise of this
Warrant have been registered under the Securities Act or any applicable state
securities or blue sky law (collectively, "Securities Laws"); (ii) agrees not
to sell, transfer or otherwise dispose of this Warrant or any such shares of
Common Stock without such registration unless the sale, transfer or
disposition can be effected without such registration and in compliance with
the Securities Laws; and (iii) agrees not to transfer this Warrant or any
portion thereof or interest therein except to a Permitted Assignee.  In the
event the Company desires to obtain an opinion from counsel that any
disposition described above in clause (ii) can be effected without
registration in compliance with the Securities Laws, the Company shall use
its best efforts to obtain such opinion promptly (and in no event more than
thirty (30) days) after notice of such intended disposition and the Company
shall bear all costs and expenses associated with obtaining such opinion.
Any certificate for shares of Common Stock issued upon exercise of this
Warrant shall bear an appropriate legend describing the foregoing
restrictions, unless such shares of Common Stock have been effectively
registered under the applicable Securities Laws.

       Section 3.02  PROVISION OF INFORMATION BY HOLDER.  The Holder shall
make available to the Company such written information, presented in form and
content satisfactory to the Company, as the Company may reasonably request,
from time to time, in order to make the determination provided for in Section
3.01.

                                  ARTICLE IV.

                              REGISTRATION RIGHTS

The following provisions shall apply irrespective of whether the Holder holds
this Warrant or has exercised this Warrant and holds Warrant Shares, and
shall apply during the period beginning on the Original Issue Date and
continuing until the Expiration Date:

       Section 4.01  PIGGYBACK REGISTRATIONS.  Whenever the Company proposes
to register any of its securities under the Securities Act (whether for the
sale by the Company or by holders thereof) and the registration form to be
used can be used for the registration of the Warrant Shares (a "Piggyback
Registration"), the Company shall give prompt written notice (in any event
within ninety (90) days prior to filing of any such registration statement by
the Company) to all holders of Warrant Shares of its intention to effect such
a registration and shall include in such registration all Warrant Shares with
respect to which the Company has received written requests for inclusion,
such requests for inclusion must be made within forty-five (45) days after
the receipt of the Company's notice.  The Registration Expenses, hereinafter
defined, of the holders of Warrant Shares shall be paid by the Company in all
Piggyback Registrations.

                                       7

<PAGE>

       Section 4.02  DEMAND REGISTRATIONS.  At any time on or after the
Original Issue Date, the Holder may notify the Company in writing (a "Demand
Notice") demanding that the Company file with the SEC a registration
statement on an appropriate form (a "Demand Registration") registering all of
the Warrant Shares to permit the public offering and resale of the Warrant
Shares.  Within thirty (30) days following a Demand Notice, the Company shall
file with the SEC such registration statement registering all of the Warrant
Shares for public offering and resale.  The Company shall promptly respond to
any SEC comments on such registration statement and shall otherwise use its
best efforts to cause such registration statement to be declared effective at
the earliest possible date.  The Registration Expenses, as hereinafter
defined, of the holders of Warrant Shares shall be shared equally by the
Company and FINOVA in all Demand Registrations.

       Section 4.03  REGISTRATION PROCEDURES.  Whenever the holders of
Warrant Shares have requested a Piggyback or Demand Registration, the Company
shall use its best efforts to effect the registration of such Warrant Shares
in accordance with the intended method of disposition thereof, and pursuant
thereto, the Company shall as expeditiously as possible:

                     (a)   prepare and file with the Securities and Exchange
       Commission a registration statement with respect to such Warrant
       Shares, which registration statement shall state that the holders of
       Warrant Shares covered thereby may sell such Warrant Shares under such
       registration statement and use its best efforts to cause such
       registration statement to become effective (provided that before
       filing a registration statement or prospectus or any amendments or
       supplements thereto, the Company shall furnish to the counsel selected
       by the holders of a majority of the Warrant Shares covered by such
       registration statement copies of all such documents proposed to be
       filed, which documents shall be subject to the review of such counsel)
       and to remain effective until the earlier of (i) the sale of such
       Warrant Shares so registered and (ii) twelve (12) months after the
       registration statement becomes effective in the case of a Piggyback
       Registration or nine (9) months after the registration statement
       becomes effective in the case of a Demand Registration;

                     (b)   prepare and file with the Securities and Exchange
       Commission such amendments and supplements to such registration
       statement and the prospectus used in connection therewith as may be
       necessary to keep such registration statement effective for the period
       described above in Section 4.03(a) and comply with the provisions of
       the Securities Act with respect to the disposition of all securities
       covered by such registration statement during such period in
       accordance with the intended methods of disposition by the sellers
       thereof set forth in such registration statement;

                     (c)   furnish to each seller of Warrant Shares such
       number of copies of such registration statement, each amendment and
       supplement thereto, the prospectus included in such registration
       statement (including each preliminary prospectus) and such other
       documents as such seller may reasonably request in order to facilitate
       the disposition of the Warrant Shares owned by such seller;


                                       8
<PAGE>

             (d)     if necessary, register or qualify the Warrant Shares
     covered by such registration statement under the securities or blue sky
     laws of such states as the Holders participating in the registration
     shall reasonably request, maintain any such registration or qualification
     current for the period described above in Section 4.03(a) above, and take
     any and all other actions either necessary or advisable to enable such
     Holders to consummate the public sale or other disposition of the Warrant
     Shares in jurisdictions where such Holders desire to effect such sales or
     other disposition;

             (e)     notify each seller of such Warrant Shares, at any
     time when a prospectus relating thereto is required to be delivered under
     the Securities Act, of the happening of any event as a result of which
     the prospectus included in such registration statement contains an untrue
     statement of a material fact or omits any fact necessary to make the
     statements therein not misleading, and, at the request of any such
     seller, the Company shall prepare a supplement or amendment to such
     prospectus so that, as thereafter delivered to the purchasers of such
     Warrant Shares, such prospectus shall not contain, to the Company's
     knowledge, an untrue statement of a material fact or omit to state any
     fact necessary to make the statements therein not misleading;

             (f)     cause all such Warrant Shares to be listed on each
     securities exchange on which similar securities issued by the Company are
     listed;

             (g)     provide a transfer agent and registrar for all such
     Warrant Shares not later than the effective date of such registration
     statement;

             (h)     enter into such customary agreements (including an
     underwriting agreement in customary form) and take all such other actions
     as the holders of a majority of the Warrant Shares being sold or the
     underwriters, if any, reasonably request in order to expedite or
     facilitate the disposition of such Warrant Shares (including, without
     limitation, effecting a stock split or a combination of shares);

             (i)     make available for inspection by any seller of
     Warrant Shares, any underwriter participating in any disposition pursuant
     to such registration statement, and any attorney, accountant or other
     agent retained by any such seller or underwriter, all financial and other
     records, pertinent corporate documents and properties of the Company, and
     cause the Company's officers, directors and employees to supply all
     information reasonably requested by any such seller, underwriter,
     attorney, accountant or agent in connection with such registration
     statement; and use its best efforts to cause such Warrant Shares covered
     by such registration statement to be registered with or approved by such
     other governmental agencies or authorities as may be necessary to enable
     the sellers thereof to consummate the disposition of such Warrant Shares;
     and

             (j)     use its best effort to furnish, at the request of
     any seller of the Warrant Shares or any underwriter of any distribution
     of the Warrant Shares, an opinion of legal counsel to the Company,
     covering such matters as are typically covered by opinions of issuer's
     counsel in similar offerings under the Securities Act.

     expenses (including, without limitation, all salaries and expenses of its
     officers and employees performing legal or accounting duties), the
     expense of any annual audit, the expense of any liability insurance and
     the expenses and fees for listing the securities to be registered on each

             (b)     The Company shall reimburse the holders of Warrant
     Shares covered by a registration for the fees and disbursements of

     Section 4.05   INDEMNIFICATION.

             (a)     The Company agrees to indemnify, to the extent
     permitted by law, each holder of Warrant Shares, its officers and
     directors and each individual or entity who controls such holder (within
     the meaning of the Securities Act) against all losses, claims, damages,
     liabilities and expenses caused by any untrue or alleged untrue statement
     of material fact contained in any registration statement, prospectus or
     preliminary prospectus or any omission or alleged omission to state
     therein a material fact required to be stated therein or necessary to
     make the statements therein not misleading, except insofar as the same
     are caused by or contained in any information furnished in writing to the
     Company by such holder expressly for use herein or by such holder's
     failure to deliver a copy of the registration statement or prospectus or
     any amendments or supplements thereto after the Company has furnished
     such holder with a sufficient number of copies of the same. hi connection
     with an underwritten offering, the Company shall indemnify such
     underwriters, their officers and directors and each individual or entity
     who controls such underwriters (within the meaning of the Securities Act)
     to the same extent as provided above with respect to the indemnification
     of the holders of Warrant Shares.

             (b)     In connection with any registration statement in
     which a holder of Warrant Shares is participating, each such holder shall
     furnish to the Company in writing such information and affidavits as the
     Company reasonably requests for use in connection with any such
     registration statement or prospectus and to the extent permitted by law,
     agrees and shall indemnify the Company, its directors and officers and
     each individual or entity who controls the Company (within the meaning of
     the Securities Act) against any

                                      10
<PAGE>

     losses, claims, damages, liabilities and expenses resulting from any
     untrue or alleged untrue statement of material fact or any omission or
     alleged omission of a material fact required to be stated in the
     registration statement or prospectus or any amendment thereof or
     supplement thereto or necessary to make the statements therein not
     misleading, but only to the extent that such untrue statement or omission
     is contained in any information or affidavit so furnished in writing by
     such holder; provided that the obligation to indemnify shall be several,
     not joint and several, among such holders of Warrant Shares and the
     liability of each such holder of Warrant Shares shall be limited to the
     net amount received by such holder from the sale of Warrant Shares
     pursuant to such registration statement.

             (c)     Any individual or entity entitled to
     indemnification hereunder shall (i) give prompt written notice to the
     indemnifying party of any claim with respect to which it seeks
     indemnification and (ii) unless in such indemnified party's reasonable
     judgment a conflict of interest between such indemnified and indemnifying
     parties may exist with respect to such claim, permit such indemnifying
     party to assume the defense of such claim with counsel reasonably
     satisfactory to the indemnified party. If such defense is assumed, the
     indemnifying party shall not be subject to any liability for any
     settlement made by the indemnified party without its consent (but such
     consent shall not be unreasonably withheld). An indemnifying party who is
     not entitled to, or elects not to, assume the defense of a claim shall
     not be obligated to pay the fees and expenses of more than one counsel
     for all parties indemnified by such indemnifying party with respect to
     such claim, unless in the reasonable judgment of any indemnified party a
     conflict of interest may exist between such indemnified party and any
     other of such indemnified parties with respect to such claim.

     Section 4.06   RULE 144 AND RULE 144A REPORTING. With a view to making
available the benefits of certain Securities Laws which may at any time
permit the sale of the Warrant Shares to the public without registration, the
Company agrees to use its best efforts to:

             (a)     Make and keep public information available, as
     those terms are understood and defined in Rule 144 under the Securities
     Act.

             (b)     File with the Securities and Exchange
     Commission in a timely manner all reports and other documents required of
     the Company under the Securities Act and the Securities Exchange Act of
     1934, as amended (the "Exchange Act").

             (c)     So long as a Holder owns any Warrant Shares,
     furnish to such Holder forthwith upon request a written statement by the
     Company as to its compliance with the reporting requirements of said Rule
     144, and of the Securities Act and the Exchange Act, a copy of the most
     recent annual or quarterly report of the Company, and such other reports
     and documents of the Company, and such other reports and documents so
     filed as a Holder may reasonably request in availing itself of any rule
     or regulation of the Securities and Exchange Commission allowing such
     Holder to sell any such securities without registration.

                                      11
<PAGE>

             (d)     If the Company is no longer subject to Section
     13 or 15(d) of the Exchange Act, to provide to the Holder or any
     prospective purchaser of the Holder's Warrant or Warrant Shares, to the
     extent available, the information required to be delivered under
     Paragraph (d)(4) of Rule 144A ("Rule 144A")(or any similar rule then in
     effect) promulgated by the Securities and Exchange Commission under the
     Securities Act in respect of a transaction qualifying for an exemption
     under Rule 144A and it will take such further action as a Holder may
     reasonably request, all to the extent required from time to time, to
     enable such Holder to sell its Warrant or Warrant Shares without
     registration under the Securities Act pursuant to Rule 144A.



                                  ARTICLE IV.

                                  DEFINITIONS

     As used herein, the following terms shall have the meanings
specified below:

     "DEEMED ADDITIONAL SHARES" shall mean (i) in the case of the
issuance of Common Stock for a consideration per share less than the
Market Value thereof, a number of shares of Common Stock equal to the
number obtained by subtracting (x) the number of shares of Common Stock
that would have been issued for the total consideration being paid in
connection with such issuance, if the price per share of the Common Stock
issued equalled the Market Value thereof immediately prior to such
issuance from (y) the number of shares of Common Stock so issued; or (ii)
in the case of the grant or issuance of an Option or Convertible
Security, a number of shares of Common Stock equal to the number obtained
by subtracting (x) the number of shares of Common Stock that would be
issuable under such exercise, conversion or exchange if the Price per
Share payable thereon equalled the Market Value of shares of Common Stock
immediately prior to such grant or issuance, from (y) the number of
shares of Common Stock issuable upon the exercise, conversion or exchange
thereof.

     "INDEPENDENT APPRAISAL" shall mean an evaluation of the price that
would be paid if the Company were sold at that time on an orderly basis
as a going concern, which evaluation shall be made by an Independent
Financial Expert.

     "INDEPENDENT FINANCIAL EXPERT" shall mean an independent financial
expert selected by the Company's Board of Directors on not less than ten (10)
days prior written notice to the Holder but shall not include any independent
financial expert to whom the Holder shall object in writing not later than
ten (10) days after the Board's delivery of notice of selection.

     "MARKET VALUE" of a share of Common Stock of the Company shall be:

          (i)   if the Common Stock is listed on a national securities
exchange, the closing price of such Common Stock on the principal national
securities exchange on which such Common Stock is traded on the date for
which any determination of Market

                                      12

<PAGE>

Value is made for any purpose hereunder ("Determination Date"), or, if there
shall have been no sales on any such exchange on the Determination Date, the
average of the highest bid and lowest asked prices on such principal exchange
on such Determination Date; or

             (ii)    if the Common Stock is not listed on a national
     securities exchange, the closing price on the NASD's National Market
     System, or, if there shall have been no sales on the Determination Date
     on the National Market System, the average of highest bid and lowest
     asked prices on the Determination Date on the National Market System, as
     applicable; or

             (iii)   if the Common Stock is not listed on a securities
     exchange or the National Market System, the average of the representative
     bid and asked prices of the Stock as of the close of trading on the
     Determination Date as quoted in the NASDAQ System; or

             (iv)    if the Common Stock is not quoted in the NASDAQ System,
     the average of the high and low bid and asked prices on the Determination
     Date in the over-the-counter market as reported by the NASD Bulletin
     Board, the National Quotation Bureau, Incorporated, or any similar
     successor organization; or

             (v)     if the Common Stock is not listed on or traded in any
     recognized securities market, such value as the Company and the Holder
     may agree upon; or

             (vi)    if the Company and the Holder cannot agree on a value
     for the Common Stock within thirty (30) days after the Company or the
     Holder has made a written proposal with respect to such value to the
     other party, the fair market value of the Stock as of the Determination
     Date as determined by an Independent Appraisal. The fees and expenses
     incurred by the Independent Financial Expert in rendering its Independent
     Appraisal shall be paid by the Company. The determination of the Market
     Value of the Common Stock shall be based solely upon the value of the
     Company and shall be computed by dividing the amount that represents the
     value of the Company by the number of outstanding shares of Common Stock.
     In making such a valuation, items such as discounts for minority
     interests, lack of marketability of the Common Stock or blockage shall
     not be considered.

     "PERMITTED ASSIGNEE" shall mean any individual or entity who receives
valid title and interest to this Warrant or any portion thereof and who
additionally accepts by written instrument each of the terms and conditions
that govern the ownership of this Warrant.

     "PRICE PER SHARE" for shares of Common Stock issuable upon the
conversion of Convertible Securities or the exercise of Options shall be
determined by dividing (i) the sum of (A) the total amount of consideration,
if any, received or receivable by the Company as consideration for the
granting of such Options or the issuance of such Convertible Securities plus
(B) the minimum aggregate amount of additional consideration payable to the
Company upon the exercise of all such Options or the conversion or exchange
of such Convertible Securities into Common Stock plus (C) in the case of all
such Options that relate to Convertible Securities, the minimum aggregate
amount of additional consideration, if any, payable upon the issuance of all


                                      13

<PAGE>

such Convertible Securities and upon conversion or exchange of all such
Convertible Securities into Common Stock, by (ii) the total number of shares
of Common Stock issuable upon the exercise of such Options or upon the
conversion or exchange of all such Convertible Securities.

                                  ARTICLE VI.

                             CONTINUING PERSONAL GUARANTY


       FOR VALUE RECEIVED, and in consideration of any lease, capital lease,
loan, or other financial accommodation heretofore or hereafter at any time made
or granted to MOBILE PET SYSTEMS, INC., a Delaware corporation ("Lessee"), by
FINOVA CAPITAL CORPORATION ("Lessor"), the undersigned, PAUL J. CROWE
("Guarantor"), hereby agrees as follows:

       1.     GUARANTY OF OBLIGATIONS. (a) Guarantor unconditionally, absolutely
and irrevocably guarantees the full and prompt payment and performance when due,
whether by acceleration or otherwise, and at all times thereafter, of all
obligations of Lessee to Lessor, howsoever created, arising or evidenced,
whether direct or indirect, absolute or contingent, or now or hereafter existing
or due or to become due, including, without limitation, under or in connection
with that certain Equipment Lease No. 4125 of even date herewith by and between
Lessee and Lessor (the "Lease"), and each of the documents, instruments and
agreements executed and delivered in connection therewith, but solely with
respect to those items of equipment which are included on Lease Schedule No.
4125.01 attached to the Lease, as each may be modified, amended, supplemented or
replaced from time to time (all such obligations are herein referred to
collectively as the "Liabilities", and the Lease and all other documents
evidencing or securing any of the Liabilities are herein referred to,
collectively, as the "Lease Documents"). This Continuing Personal Guaranty (this
"Continuing Guaranty") is a guaranty of payment and performance when due and not
of collection. Terms used herein with initial capital letters, which are not
otherwise defined herein, shall have the meanings given such terms in the Lease.

       (b)    In the event of any default by Lessee in making payment of, or
default by Lessee in performance of, any of the Liabilities, Guarantor agrees
on demand by Lessor to pay and perform all of the Liabilities as are then or
thereafter become due and owing or are to be performed under the terms of the
Lease Documents.  Guarantor further agrees to pay all expenses (including
reasonable attorneys' fees and expenses) paid or incurred by Lessor in
endeavoring to collect the Liabilities, or any part thereof, and in enforcing
this Continuing Guaranty (herein, the "Collection Costs").

       2.     CONTINUING NATURE OF GUARANTY AND LIABILITIES.  This Continuing
Guaranty shall be continuing and shall not be discharged, impaired or affected
by:
              a.     the insolvency of Lessee or the payment in full of all of
                     the Liabilities at any time or from time to time;

              b.     the power or authority or lack thereof of Lessee to incur
                     the Liabilities;

<PAGE>

              c.     the validity or invalidity of any of the Lease Documents or
                     the documents securing the same;

              d.     the existence or non-existence of Lessee as a legal entity;

              e.     any transfer by Lessee of all or any part of any collateral
                     in which Lessor has been granted a lien or security
                     interest pursuant to the Lease Documents;

              f.     any statute of limitations affecting the liability of
                     Guarantor under this Continuing Guaranty or the Lease
                     Documents or the ability of Lessor to enforce this
                     Continuing Guaranty or any provision of the Lease
                     Documents; or

              g.     any right of offset, counterclaim or defense of Guarantor,
                     including, without limitation, those which have been waived
                     by Guarantor pursuant to Section 7 hereof.

       3.     INSOLVENCY OF LESSEE OR GUARANTOR.  Without limiting the
generality of any other provision hereof, Guarantor agrees that, in the event of
the dissolution or insolvency of Lessee or Guarantor or the inability of Lessee
or Guarantor to pay their respective debts as they mature, or an assignment by
Lessee or Guarantor for the benefit of creditors, or the institution of any
proceeding by or against Lessee or Guarantor alleging that Lessee or Guarantor
is insolvent or unable to pay their respective debts as they mature, Guarantor
will pay to Lessor forthwith the full amount which would be payable hereunder by
Guarantor if all of the Liabilities were then due and payable, whether or not
such event occurs at a time when any of the Liabilities are otherwise due and
payable.

       4.     PAYMENT OF THE LIABILITIES.  Any amounts received by Lessor from
whatever source on account of the Liabilities may be applied by Lessor toward
the payment of such of the Liabilities, and in such order of application, as
Lessor may from time to time elect, and notwithstanding any payments made by or
for the account of Guarantor pursuant to this Continuing Guaranty.

       5.     REINSTATEMENT.  Guarantor agrees that, if at any time all or any
part of any payment theretofore applied by Lessor to any of the Liabilities is
or must be rescinded or returned by Lessor for any reason whatsoever (including,
without limitation, the insolvency, bankruptcy or reorganization of Lessee),
such Liabilities shall, for the purposes of this Continuing Guaranty and to the
extent that such payment is or must be rescinded or returned, be deemed to have
continued in existence notwithstanding such application by Lessor, and this
Continuing Guaranty shall continue to be effective or be reinstated, as the case
may be, as to such Liabilities, all as though such application by Lessor had not
been made.

       6.     PERMITTED ACTIONS OF LESSOR.  Lessor may from time to time, in its
sole discretion and without notice to Guarantor, take any or all of the
following actions:


                                          2

<PAGE>

              a.     retain or obtain a security interest in any assets of
       Lessee or any third party to secure any of the Liabilities or any
       obligations of Guarantor hereunder;

              b.     retain or obtain the primary or secondary obligation of any
       obligor or obligors, in addition to Guarantor, with respect to any of the
       Liabilities;

              c.     extend or renew for one or more periods (whether or not
       longer than the original period), alter or exchange any of the
       Liabilities;

              d.     waive, ignore or forbear from taking action or otherwise
       exercising any of its default rights or remedies with respect to any
       default by Lessee under the Lease Documents;

              e.     release, waive or compromise any obligation of Guarantor
       hereunder or any obligation of any nature of any other obligor primarily
       or secondarily obligated with respect to any of the Liabilities;

              f.     release its security interest in, or surrender, release or
       permit any substitution or exchange for, all or any part of any
       collateral now or hereafter securing any of the Liabilities or any
       obligation hereunder, or extend or renew for one or more periods (whether
       or not longer than the original period) or release, waive, compromise,
       alter or exchange any obligations of any nature of any obligor with
       respect to any such property; and

              g.     demand payment or performance of any of the Liabilities
       from Guarantor at any time or from time to time, whether or not Lessor
       shall have exercised any of its rights or remedies with respect to any
       property securing any of the Liabilities or any obligation hereunder or
       proceeded against any other obligor primarily or secondarily liable for
       payment or performance of any of the Liabilities.

       7.     SPECIFIC WAIVERS.  Without limiting the generality of any other
provision of this Continuing Guaranty, Guarantor hereby expressly waives:

              a.     notice of the acceptance by Lessor of this Continuing
              Guaranty;

              b.     notice of the existence, creation, payment, nonpayment,
              performance or nonperformance of all or any of the Liabilities;

              c.     presentment, demand, notice of dishonor, protest, notice of
              protest and all other notices whatsoever with respect to the
              payment or performance of the Liabilities or the amount thereof or
              any payment or performance by Guarantor hereunder;


                                          3
<PAGE>

                     d.     all diligence in collection or protection of or
                     realization upon the Liabilities or any thereof, any
                     obligation hereunder or any security for or guaranty of any
                     of the foregoing;

                     e.     any right to direct or affect the manner or timing
                     of Lessor's enforcement of its rights or remedies;

                     f.     any and all defenses which would otherwise arise
                     upon the occurrence of any event or contingency described
                     in Section 1 hereof or upon the taking of any action by
                     Lessor permitted hereunder;

                     g.     any defense, right of set-off, claim or counterclaim
                     whatsoever and any and all other rights, benefits,
                     protections and other defenses available to Guarantor now
                     or at any time hereafter, including, without limitation,
                     under California Civil Code Sections 2787 to 2855,
                     inclusive, and California Code of Civil Procedure Sections
                     580a, 580b, 580d or 726, and all successor sections; and

                     h.     all other principles or provisions of law, if any,
                     that conflict with the terms of this Continuing Guaranty,
                     including, without limitation, the effect of any
                     circumstances that may or might constitute a legal or
                     equitable discharge of a guarantor or surety.

              8.     IRREVOCABILITY.  Guarantor hereby further waives all rights
to revoke this Continuing Guaranty at any time, and all rights to revoke any
agreement executed by Guarantor at any time to secure the payment and
performance of Guarantor's obligations under this Continuing Guaranty.

              9.     STATUTORY WAIVER OF RIGHTS AND DEFENSES REGARDING ELECTION
OF REMEDIES.  Guarantor waives all rights and defenses arising out of an
election of remedies by Lessor, even though that election of remedies, such as a
nonjudicial foreclosure with respect to security for a guaranteed obligation,
has destroyed Guarantor's rights of subrogation and reimbursement against Lessee
by the operation of any applicable law, including without limitation Section
580d of the California Code of Civil Procedure, or otherwise.

              10.    SUBORDINATION.  Guarantor hereby subordinates any and
all indebtedness of Lessee to Guarantor to the full and prompt payment and
performance of all of the Liabilities. Guarantor agrees that Lessor shall be
entitled to receive payment of all Liabilities prior to Guarantor's receipt
of payment of any amount of any indebtedness of Lessee to Guarantor. Any
payments on such indebtedness to Guarantor, if Lessor so requests, shall be
collected, enforced and received by Guarantor, in trust, as trustee for
Lessor and shall be paid over to Lessor on account of the Liabilities, but
without reducing or affecting in any manner the liability of Guarantor under
the other provisions of this Guaranty. Lessor is authorized and empowered,
but not obligated, in its discretion, (a) in the name of Guarantor, to
collect and enforce, and to submit claims in respect of, any indebtedness of

                                       4
<PAGE>

Lessee to Guarantor and to apply any amounts received thereon to the
Liabilities, and (b) to require Guarantor (i) to collect and enforce, and to
submit claims in respect of, any indebtedness of Lessee to Guarantor, and (ii)
to pay any amounts received on such indebtedness to Lessor for application to
the Liabilities.

              11.    SUBROGATION.  Guarantor will not exercise any rights which
it may acquire by way of subrogation under this Continuing Guaranty, by any
payment hereunder or otherwise, until all of the Liabilities have been paid in
full, in cash, and Lessor shall have no further obligations to Lessees under the
Lease Documents or otherwise. If any amount shall be paid to Guarantor on
account of such subrogation rights at any other time, such amount shall be held
in trust for the benefit of Lessor and shall be forthwith paid to Lessor to be
credited and applied to the Liabilities, whether matured or unmatured, in such
manner as Lessor shall determine in its sole discretion.

              12.    ASSIGNMENT OF LESSOR'S RIGHTS.  Lessor may, from time to
time, without notice to Guarantor, assign or transfer any or all of the
Liabilities or any interest therein and, notwithstanding any such assignment
or transfer of the Liabilities or any subsequent assignment or transfer
thereof, the Liabilities shall be and remain the Liabilities for the purpose
of this Continuing Guaranty. Each and every immediate and successive assignee
or transferee of any of the Liabilities or of any interest therein shall, to
the extent of such party's interest in the Liabilities, be entitled to the
benefits of this Continuing Guaranty to the same extent as if such assignee
or transferee were Lessor; PROVIDED, HOWEVER, that unless Lessor shall
otherwise consent in writing, Lessor shall have an unimpaired right, prior
and superior to that of any such assignee or transferee, to enforce this
Continuing Guaranty for its own benefit as to those of the Liabilities which
Lessor has not assigned or transferred.

              13.    INDULGENCES NOT WAIVERS.  No delay in the exercise of any
right or remedy shall operate as a waiver thereof, and no single or partial
exercise by Lessor of any right or remedy shall preclude other or further
exercise thereof or the exercise of any other right or remedy; nor shall any
modification or waiver of any of the provisions of this Continuing Guaranty be
binding upon Lessor, except as expressly set forth in a writing duly signed and
delivered by Lessor. No action of Lessor permitted hereunder shall in any way
affect or impair the rights of Lessor or the obligations of Guarantor under this
Continuing Guaranty.

              14.    FINANCIAL CONDITION OF LESSEE.  (a) Guarantor represents
and warrants that it is fully aware of the financial condition of Lessee, and
Guarantor delivers this Continuing Guaranty based solely upon its own
independent investigation of Lessee's financial condition and in no part upon
any representation or statement of Lessor with respect thereto. Guarantor
further represents and warrants that it is in a position to and hereby does
assume full responsibility for obtaining such additional information concerning
Lessee's financial condition as Guarantor may deem material to its obligations
hereunder, and Guarantor is not relying upon, nor expecting Lessor to furnish it
any information in Lessor's


                                       5
<PAGE>

possession concerning Lessee's financial condition or concerning any
circumstances bearing on the existence or creation, or the risk of nonpayment or
nonperformance of the Liabilities.

              (b)    Without limiting the generality of Section 14(a) above,
Guarantor hereby waives any duty on the part of Lessor to disclose to
Guarantor any facts it may now or hereafter know about Lessee, regardless of
whether Lessor has reason to believe that any such facts materially increase
the risk beyond that which Guarantor intends to assume or has reason to
believe that such facts are unknown to Guarantor. In addition, Guarantor
hereby knowingly accepts the full range of risk encompassed within a contract
of "Continuing Guaranty" which includes, without limitation, the possibility
that Lessee will contract for additional indebtedness for which Guarantor may
be liable hereunder after Lessee's financial condition or ability to pay its
lawful debts when they fall due has deteriorated.

              15.    REPRESENTATIONS AND WARRANTIES.  Guarantor represents and
warrants to Lessor that each of the following statements is accurate and
complete as of the date of this Continuing Guaranty:

                     a.     this Continuing Guaranty has been duly executed and
              delivered by Guarantor and constitutes a legal, valid and binding
              obligation of Guarantor, enforceable against Guarantor in
              accordance with its terms, except as limited by bankruptcy,
              insolvency or other laws of general application relating to or
              affecting the enforcement of creditors' rights generally;

                     b.     the execution, delivery and performance of this
              Continuing Guaranty do not (i) violate any provisions of law or
              any order of any court or other agency of government (each, a
              "Requirement of Law"), (ii) contravene any provision of any
              material contract or agreement to which Guarantor is a party or by
              which Guarantor or Guarantor's assets are bound (each, a
              "Contractual Obligation"), or (iii) result in the creation or
              imposition of any lien, charge or encumbrance of any nature upon
              any property, asset or revenue of Guarantor;

                     c.     all consents, approvals, orders and authorizations
              of, and registrations, declarations and filings with, any
              governmental agency or authority or other person or entity
              (including, without limitation, the members, shareholders or
              partners of any entity), if any, which are required to be obtained
              in connection with the execution and delivery of this Continuing
              Guaranty or the performance of Guarantor's obligations hereunder
              have been obtained, and each is in full force and effect;

                     d.     Guarantor has paid all taxes and other charges
              imposed by any governmental agency or authority due and payable by
              Guarantor other than those which are being challenged in good
              faith by appropriate proceedings;


                                       6
<PAGE>

                     e.     Guarantor is not in violation of any Requirement of
              Law or Contractual Obligation other than any violation the
              consequences of which could not have a material adverse effect on
              Guarantor's ability to perform its obligations hereunder
              (a "Material Adverse Effect"); and

                     f.     no action, proceeding, investigation or litigation
              is pending or, to the knowledge of Grantor, overtly threatened
              against Guarantor by any person or entity which, if adversely
              determined, could have a Material Adverse Effect.

              16.    GUARANTOR FINANCIAL INFORMATION. Guarantor will provide
Lessor in writing such financial and other information with respect to
Guarantor's assets and liabilities as Lessor shall reasonably request from time
to time, in form satisfactory to Lessor.

              17.    BINDING UPON SUCCESSORS; DEATH OF GUARANTOR. This
Continuing Guaranty shall be binding upon Guarantor and Guarantor's successors
and assigns and shall inure to the benefit of Lessor and its successors and
assigns. All references herein to Lessee shall be deemed to include its
successors and assigns, and all references herein to Guarantor shall be deemed
to include Guarantor named herein, it's successors and assigns, and in the event
of a death of a Guarantor, the duly appointed representative, executor or
administrator of the deceased Guarantor's estate.

              18.    OBLIGATIONS JOINT AND SEVERAL. In addition and
notwithstanding anything to the contrary contained in this Continuing
Guaranty or in any other document, instrument or agreement between or among
any of Lessor, Lessee, Guarantor or any third party, the obligations of
Guarantor with respect to the Liabilities shall be joint and several with any
other person or entity that now or hereafter executes a guaranty of any of
the Liabilities separate from this Continuing Guaranty.

              19.    NOTICES. All notices required or permitted to be given
hereunder shall be in writing and shall be either personally delivered,
transmitted by facsimile to the facsimile numbers provided herein or sent by
United States certified or registered mail, return receipt requested, addressed
to Guarantor or Lessor at their respective addresses stated below or at such
other address as either party hereafter notifies the other party as herein
provided. Notices shall be deemed received on the earlier of (i) the date noted
on the return receipt as delivered if mail delivery of the notice is successful
or the date inscribed on a confirmation of successful transmission, if sent by
facsimile; (ii) the last date of attempted delivery, as noted by the United
States Postal Service on the envelope containing the notice, if mail delivery is
unsuccessful; or (iii) the date of the actual delivery if personally delivered.

             20. GOVERNING LAW; ADDITIONAL WAIVERS. (a) This Continuing Guaranty
has been delivered and shall be governed by and construed in accordance with the
internal laws (as opposed to the conflicts of law provisions) of the State of
Arizona, provided that


                                       7
<PAGE>

Guarantor agrees that each of the waivers and agreements of Guarantor herein
which refer to provisions of the California Civil Code and the California Code
of Civil Procedure shall be effective and enforceable to the extent permitted
under applicable law, and to the extent that any court of competent jurisdiction
shall apply the laws of the State of California to determine the relative rights
or remedies of Lessor and Guarantor hereunder, such waivers and agreements by
Guarantor shall be governed by the laws of the State of California.

       (b)    GUARANTOR HEREBY:

                     (i)    WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION TO
       ENFORCE OR DEFEND ANY MATTER ARISING FROM OR RELATED TO THIS CONTINUING
       GUARANTY, AND ACKNOWLEDGES THAT LESSOR ALSO WAIVES SUCH RIGHT;

                     (ii)   IRREVOCABLY SUBMITS TO THE JURISDICTION OF ANY STATE
       OR FEDERAL COURT LOCATED IN MARICOPA COUNTY, ARIZONA, OVER ANY ACTION OR
       PROCEEDING TO ENFORCE OR DEFEND ANY MATTER ARISING FROM OR RELATED TO
       THIS CONTINUING GUARANTY;

                     (iii)  IRREVOCABLY WAIVES, TO THE FULLEST EXTENT GUARANTOR
       MAY EFFECTIVELY DO SO, THE DEFENSE OF AN INCONVENIENT FORUM TO THE
       MAINTENANCE OF ANY SUCH ACTION OR PROCEEDING;

                     (iv)  agrees that a final judgment in any such action or
       proceeding shall be conclusive and may be enforced in any other
       jurisdictions by suit on the judgment or in any other manner provided
       by law; and

                     (v)   agrees not to institute any legal action or
       proceeding against Lessor or any of Lessor's directors, officers,
       employees, agents or property concerning any matter arising out of or
       relating to this Continuing Guaranty in any court other than one located
       in Maricopa County, Arizona.

              (c)    Nothing herein shall affect or impair Lessor's right to
serve legal process in any manner permitted by law or Lessor's right to bring
any action or proceeding against Guarantor or its property in the courts of any
other jurisdiction. Wherever possible each provision of this Continuing Guaranty
shall be interpreted as to be effective and valid under applicable law, but if
any provision of this Continuing Guaranty shall be prohibited by or invalid
under such law, such provision shall be ineffective only to the extent of such
prohibition or invalidity, without invalidating the remainder of such provision
or the remaining provisions of this Continuing Guaranty.

              21.    ADVICE OF COUNSEL. GUARANTOR ACKNOWLEDGES THAT GUARANTOR
HAS EITHER OBTAINED THE ADVICE OF COUNSEL OR HAS


                                       8
<PAGE>

HAD THE OPPORTUNITY TO OBTAIN SUCH ADVICE IN CONNECTION WITH THE TERMS AND
PROVISIONS OF THIS CONTINUING GUARANTY.

              22.    ENTIRE AGREEMENT. This Continuing Guaranty contains the
complete understanding of the parties hereto with respect to the subject
matter herein. Guarantor acknowledges that Guarantor is not relying upon any
statements or representations of Lessor not contained in this Continuing
Guaranty and that such statements or representations, if any, are of no force
or effect and are fully superseded by this Continuing Guaranty. This
Continuing Guaranty may only be modified by a writing executed by Guarantor
and Lessor.

              23.    CONSIDERATION. Guarantor is a founder of and shareholder in
Lessee, and as such stands to benefit economically and materially from Lessee's
ability to successfully operate its business. The accommodations being provided
by Lessor to Lessee pursuant to the Lease represent Lessee's first acquisition
of the assets necessary to operate it's business. Accordingly, Guarantor
acknowledges the receipt of full and adequate consideration in return for this
Continuing Guaranty through the economic benefits Guarantor expects to derive as
a result of his ownership interest in Lessee.

              24.    TERMINATION OF CONTINUING GUARANTY. In connection with
the execution and delivery of the Lease, Guarantor acknowledges and agrees
that he has, both on behalf of Lessee and on behalf of himself individually,
petitioned Lessor to enter into the Lease and to provide the financial
accommodations created thereby in order to induce the manufacturer of the
Equipment listed on Lease Schedule No. 4125.01 to the Lease to make such
Equipment available to Lessee at this time, notwithstanding the fact that at
the time the Lease is being entered into, all conditions precedent to
Lessor's commitment to enter into the Lease have not been satisfied. Lessor
has agreed to enter into the Lease at this time, conditioned upon Guarantor's
execution and delivery of this Continuing Guaranty in favor of Lessor. Lessor
hereby agrees that, notwithstanding anything to the contrary contained
herein, but provided that no default under the Lease then exists, this
Continuing Guaranty shall be terminated and released (subject to
reinstatement in accordance with Section 5 hereof) at such time as Lessee has
provided to Lessor documentation substantiating that, with respect to the
specific items of Equipment listed on Schedule 1 to the Lease, Lessee has in
effect signed, valid and enforceable contractual agreements (each of which
must be in form and substance satisfactory to Lessor) with one or more
hospitals (the creditworthiness of which must be satisfactory to Lessor in
all respects), which agreements will provide Lessee with a minimum of
eighty-eight (88) positron emission tomography ("PET") procedures per month,
for a term that shall not expire prior to the date final payment is due under
the Lease, with respect to the items of Equipment listed on Lease Schedule
No. 4125.01 to the Lease. Lessor shall be entitled to perform its own due
diligence with respect to each hospital which is to become party to any such
contract, to determine whether such hospital is satisfactorily creditworthy,
in Lessor's sole discretion.

                  IN WITNESS WHEREOF, Guarantor has executed this Continuing
Guaranty effective as of the 8th day of April, 1999.

                         COLLATERAL ASSIGNMENT OF AGREEMENTS


       1.     FOR VALUE RECEIVED, the undersigned (hereinafter referred to as
the "Assignor") hereby grants a security interest in and collaterally assigns
and transfers to FINOVA Capital Corporation, a Delaware corporation, having
an office at 311 South Wacker Drive, Suite 4400, Chicago, Illinois 60606
(hereinafter referred to as the "Assignee"), all right, title and interest of
the Assignor in and to, all benefits of the Assignor under, and all monies
due or to become due to the Assignor under or in connection with, those
certain Positron Emission Tomography Mobile Services Agreements (each, an
"Agreement") of various dates by and between Assignor and the various
hospitals, health centers, and other health care service agencies or
providers party thereto (each of which is referred to as "Client" both herein
and in the applicable Agreement to which it is a party), whether now in
effect or hereafter entered into, as the same may exist from time to time
between Assignor and the various Clients (all such Agreements as may now or
hereafter be in effect between Assignor and the various Clients are
collectively referred to herein as the "Agreements"), as collateral security
for any and all of the Assignor's obligations arising pursuant to that
certain Equipment Lease No. 4125 dated of even date herewith, together with
each and every schedule attached to such Equipment Lease, each of which
schedules designates one or more items of equipment that are to be leased to
Assignor by Assignee (Equipment Lease No. 4125, together with each and every
schedule attached thereto, are hereinafter collectively referred to as the
"Lease") between Assignor as "Lessee" and Assignee as "Lessor" (all such
obligations of Assignor under the Lease being referred to herein as the
"Lessee's Obligations"). Capitalized terms not otherwise defined herein shall
have the meanings ascribed to them in the Lease.  Attached hereto as EXHIBIT
A is a listing of those particular Agreements which relate to the item or
items of equipment described on Schedule _____ of the Lease.

       2.     The Assignor further agrees, represents and warrants that:

              a.     The Agreements, with respect to Assignor, and with respect
   to each Client, to Assignor's best knowledge, are each valid and enforceable
   in accordance with their respective terms, have not been modified, amended,
   altered or changed in any manner, and are in full force and effect, there
   being no material default thereunder by Assignor or, to Assignor's best
   knowledge, by any Client.

              b.     Assignor has the right, power and authority to assign its
   right, title and interest in and to the Agreements to Assignee.  Assignor's
   right, title and interest in the Agreements are owned by Assignor free and
   clear of all claims, mortages, pledges, liens, encumbrances and security
   interests of every nature whatsoever, except this Assignment.  Assignor will
   not sell, transfer, assign, pledge or grant a security interest in the
   Agreements to any person other

<PAGE>

   than Assignee.  Any other such sale, transfer assignment, mortgage, pledge
   or encumbrance without Assignee's consent shall be void and of no force and
   effect.

              c.     Assignor will keep and perform the obligations to be kept
   and performed by it under the Agreements.

              d.     Assignor will not, without the prior written consent of
   Assignee, modify, amend, alter or change in any material respect any
   Agreement or cancel or terminate any Agreement, and will do all things
   necessary and proper to keep the Agreements in full force and effect.

              e.     Assignor specifically acknowledges and agrees that Assignee
   does not assume, and shall have no responsibility for, the payment of any
   sums due or to become due under the Agreements or the performance of any
   obligations to be performed under or with respect to the Agreements by the
   Assignor, and the Assignor hereby agrees to indemnify and hold the Assignee
   harmless with respect to any and all claims made by any person relating
   thereto.  Assignee, in its discretion, may file or record this Assignment.

              f.     If there shall be a default under any Agreement on the part
   of the Assignor, for any reason, the Assignee may, at its option ten (10)
   days after requesting that Assignor cure such default, without assuming any
   of the obligations of the Assignor under the applicable Agreement and
   without waiving or releasing the Assignor from any of the terms hereof or
   any of Assignor's obligations to Assignee, cure the default, and the cost of
   curing the same (and all necessary and incidental costs and expenses of the
   Assignee in connection therewith, including, but not limited to, all
   attorneys' fees), with interest at the rate of fourteen percent (14%) per
   annum, shall be deemed an advance to Assignor and part of the Lessee's
   Obligations, and shall be due and payable by the Assignor to the Assignee
   upon demand.

              g.     If a default under the Lease shall occur (herein, an "Event
   of Default") with respect to any of the Lessee's Obligations, in addition to
   all other rights and remedies of Assignee pursuant to any agreements of
   Assignor in favor of or assigned to and held by Assignee or pursuant to
   applicable law or otherwise, Assignee or its successor or designee shall
   have all rights and benefits under the Agreements, including, without
   limitation, any and all rights to receive all payments accruing to the
   benefit of Assignor thereunder, without modifying or discharging any of the
   Lessee's Obligations.  Upon the occurrence of any Event of Default, Assignor
   agrees to execute any and all documents requested by Assignee in its sole
   discretion to enable Assignee to exercise all of the rights of Assignor
   under the Agreements.  The specified remedies to which the Assignee may
   resort under the terms of this Assignment are cumulative and are not
   intended to be exclusive of any other remedies or means of redress to which
   the Assignee may be lawfully entitled in case of any breach or threatened
   breach by the Assignor of any


                                          2

<PAGE>

   provision hereof or of any of the Lessee's Obligations.  Nothing contained
   in this Assignment and no act or action taken or done by the Assignee
   pursuant to the powers and rights granted it hereunder or under any
   instrument ancillary hereto shall be deemed to be a waiver by the Assignee
   of any of its rights and remedies against the Assignor in connection with,
   or in respect of, any of the Lessee's Obligations of the Assignor to the
   Assignee.  The right of the Assignee to collect and enforce collection of
   the Lessee's Obligations and to enforce any security and collateral held by
   it may be exercised by the Assignee either prior to, simultaneously with, or
   subsequent to any action taken by the Assignee hereunder.

              h.     Following the occurrence of an Event of Default, any monies
   or other proceeds under or in connection with the Agreements received by the
   Assignor shall not be commingled with any other property of the Assignor, but
   shall be segregated, held by the Assignor in trust for, and immediately
   delivered to, the Assignee for application to the payment of the Lessee's
   Obligations.

              i.     Upon the payment and satisfaction in full of all of the
   Lessee's Obligations and the termination of the Lease, this Assignment shall
   become null and void and of no further force or effect, but the affidavit,
   certificate, letter or statement or any officer, agent or attorney of the
   Assignee showing that any part of the Lessee's Obligations remains unpaid or
   unsatisfied shall be and constitute evidence of the validity, effectiveness
   and continuing force of this Assignment and any person may, and is hereby
   authorized to, rely thereon.

              j.     The Assignee may take, or release, other security which it
   may hold for the payment of the Lessee's Obligations, may release any party
   primarily or secondarily liable therefor, and may apply any other security
   held by it to the satisfaction, or partial satisfaction, of Lessee's
   Obligations, without prejudice to any of its rights under this Assignment.

              k.     This Assignment shall inure to the benefit of the Assignee
   and its successors, assigns and designees, and shall be binding upon any
   subsequent owner of the Assignor's interest in and to the Agreements.

              l.     The Assignor covenants to execute and deliver to the
   Assignee, upon demand, such additional assurances, writings or other
   instruments as may be reasonably required by the Assignee to effectuate the
   purpose hereof.  This instrument of assignment may not be modified orally
   and is to be governed by the local laws of the State of Arizona applicable
   to contracts executed and to be performed in such state.

              m.     The Assignor hereby designates and appoints Assignee and
   each of its designees or agents as attorney-in-fact for such Assignor
   following an


                                          3
<PAGE>

Event of Default, irrevocably and with power of substitution, for purposes of
carrying out the provisions of this Assignment, with authority to execute and
deliver for and on behalf of the Assignor any and all instruments, documents,
agreements and other writings necessary or advisable for the exercise on
behalf of the Assignor of any rights, benefits or  options created or
existing under or pursuant to the Agreements; to endorse the name of the
Assignor on its behalf on any and all notes, acceptances, checks, drafts,
money orders, instruments or other evidences of collateral, that may come into
Assignee's possession; to execute proofs of claim and loss; to execute
endorsements, assignments or other instruments of conveyance and transfer; to
adjust and compromise any claims under insurance policies or otherwise; to
execute releases; and to do all other acts and things necessary and advisable
in the discretion of Assignee to carry out and enforce this Assignment or the
Lessee's Obligations. All acts done by Assignee under the foregoing
authorization are hereby ratified and approved and neither Assignee nor any
designee or agent thereof shall be liable for any acts of commission or
omission (other than acts committed or omitted through gross negligence or
willful misconduct), for any error of judgment, or for any mistake of facts
or law. This power of attorney being coupled with an interest is irrevocable
while any of the Lessee's Obligations shall remain unpaid.

         n.  If an Event of Default shall occur with respect to any of the
Lessee's Obligations, Assignee may, in its discretion, in its name or
Assignor's or otherwise, notify the Clients under each of the Agreements to make
payment to Assignee of all amounts due or to become due under such Agreements.

         o.  If an Event of Default shall occur with respect to any of the
Lessee's Obligations, Assignee may, in its discretion, demand, sue for,
collect or receive any money or property at any time payable or receivable on
account of or in exchange for any Agreement, or, with respect to payments
which have become due and payable under any Agreement, make any compromise or
settlement deemed desirable by Assignee.

         p.  Assignor will pay Assignee for any sums, costs, and expenses
which Assignee may pay or incur pursuant to the provisions of this Assignment
or in negotiating, executing, perfecting, amending, defending, protecting or
enforcing this Assignment or the security interest granted herein or in
enforcing payment of the Lessee's Obligations or otherwise in connection with
the provisions hereof, including but not limited to court costs, collection
charges, travel expenses, and attorneys' fees, all of which, together with
interest at the rate of fourteen percent (14%) per annum, shall be part of
the Lessee's Obligations and be payable on demand.

         q.  Assignor is a corporation duly organized, validly existing and in
good standing under the laws of the State of Delaware and has the

                                       4
<PAGE>

corporate power and authority to own its properties and to transact the
business in which it is engaged.

         r.  Assignor has the corporate power and authority to execute and
deliver, and to perform its obligations under, this Assignment, and has taken
all necessary corporate action to authorize the execution, delivery and
performance of this Assignment.

         s.  This Assignment constitutes the legal, valid and binding
obligation of Assignor, enforceable in accordance with its terms.

         t.  The execution, delivery and performance of this Assignment will
not violate any law or regulation, or any order or decree of any court or
governmental instrumentality, or any provision of the corporate charter or
by-laws of, or any securities issued by, Assignor, and will not conflict
with, or result in the breach of, or constitute a default under, any
indenture, mortgage, deed of trust, agreement or other instrument to which
Assignor is a party or by which it is bound, and will not result in the
creation or imposition of any lien, charge or encumbrance upon any of the
property of Assignor pursuant to the provisions of any of the foregoing.

         u.  Assignor agrees that any copy of this Assignment signed by
Assignor and transmitted by telecopy (promptly confirmed in writing) for
delivery to Assignee shall be admissible in evidence as the original itself
in any judicial or administrative proceeding, whether or not the original is
in existence.

      IN WITNESS WHEREOF, the undersigned has caused this Assignment to be
executed effective as of the 8th day of April, 1999.

                     SUBORDINATION AGREEMENT

          This Subordination Agreement (this "Agreement") is made and entered
into by and among PAUL J. CROWE ("Crowe"), JOHN FLEMING, and BRENT NELSON
("Nelson"; Crowe, Brown, and Nelson are sometimes hereinafter collectively
referred to as the "Directors"), effective as of the 8th day of April, 1999,
for the benefit of FINOVA CAPITAL CORPORATION, a Delaware corporation
("Lessor").

                         R E C I T A L S

          A.  Mobile PET Systems, Inc., a Delaware corporation ("Lessee"), is
or will be obligated to Lessor pursuant to that certain Equipment Lease No.
4125, together with each and every Lease Schedule now or hereafter to be
entered into between Lessee and Lessor and attached thereto (as amended,
restated, supplemented or modified from time to time, collectively, the
"Lease"). All obligations of Lessee to Lessor, as evidenced by the Lease, are
collectively referred to herein as the "FINOVA Debt." Except as otherwise
defined herein, all capitalized terms used herein shall have the same
meanings as set forth in the Lease.

          B.  Each of the Directors is an affiliate of Lessee, and Crowe and
Brown are also officers of Lessee. As such, each of the Directors will or may
be receiving salary, bonuses, compensation and/or other forms of
remuneration, director's fees, and dividends or other forms of capital
distributions, from Lessee (collectively herein, "Distributions"). Such
Distributions, together with any and all indebtedness of Lessee to the
Directors now existing or hereafter incurred (as such concept is more fully
elaborated upon in the following Recital C), are herein collectively referred
to as the "Director Debt."

          C.  The terms "Debt", "FINOVA Debt" and "Director Debt", as used
herein, mean all debts, obligations and liabilities, now or hereafter
existing, direct or indirect, absolute or contingent, joint or several,
secured or unsecured, due or not due, contractual or tortious, liquidated or
unliquidated, arising by operation of law or otherwise, irrespective of the
person in whose favor such debt may have originally been created and
regardless of the manner in which such debt has been or hereafter may be
acquired by Lessor in respect of the FINOVA Debt or the Directors in respect
of the Director Debt, as the case may be, and include all costs incurred to
obtain, preserve, perfect or enforce any security interest, lien or other
encumbrance securing such debt, or to collect any debt, or to maintain,
preserve, collect and enforce any collateral, and interest on all such
amounts.

          D.  The FINOVA Debt is secured by, among other things: (i) the lien
of that certain Security Agreement of even date herewith between Lessor and
Lessee pursuant to which Lessee granted in favor of Lessor a security
interest in those items of tangible and

<PAGE>

intangible personal property described on EXHIBIT A attached hereto (the
"Property"), (ii) the rights of Lessor, pursuant to the Lease, with respect to
the various items of equipment leased thereby, and (iii) that certain
Collateral Assignment of Agreements of even date herewith from Lessee in
favor of Lessor, pursuant to which Lessee has collaterally assigned to Lessor
its rights in various beneficial contractual arrangements related to the
Lease.

          NOW, THEREFORE, in consideration of Lessor's agreement to enter
into the Lease with Lessee, and for other good and valuable consideration,
the Directors hereby agree as follows:

          1.  The Director Debt shall at all times be subordinate, and is
hereby made subordinate, to the FINOVA Debt until the FINOVA Debt is paid in
full. Notwithstanding anything to the contrary in the Lessee's organizational
documents and any and all amendments thereto, no payment of any obligation,
principal or interest of any portion of the Director Debt shall be required,
demanded, made or collected until after such time as the FINOVA Debt has been
paid in full, EXCEPT that, in the absence of an event of default under the
Lease (any such default being referred to herein as an "Event of Default"),
Lessee shall be permitted to pay regularly accruing salary, bonus, and other
compensation to Crowe (at an annual level not greater than $150,000 during
the period from the date hereof through June 30, 2000, and for each
subsequent twelve-month period commencing July 1st thereafter, at a level not
greater than 125% of the total compensation paid during the prior
twelve-month period); provided, however, that until such time as Lessee has
achieved a level of Operating Cash Flow (as hereafter defined) to Contractual
Debt Service (as hereafter defined) of not less than 1.0 to 1.0, Crowe and
shall cause twenty-five percent (25%) of the foregoing amounts to be deferred
and accrued. At such time as Lessee has attained a level of Operating Cash
Flow to Contractual Debt Service (herein, the "Debt Service Coverage Ratio")
of greater than 1.0 to 1.0, Lessee shall be permitted to pay, and Crowe and
shall be permitted to receive, payments of accrued deferred compensation to
the extent such payments can be made without causing Lessee's Debt Service
Coverage Ratio to fall below 1.0 to 1.0. "Operating Cash Flow" shall mean,
for any period, Lessee's net income or loss (excluding the effect of any
extraordinary gains or losses) determined in accordance with generally
accepted accounting principles ("GAAP"), PLUS each of the following items, to
the extent deducted from the revenues of Lessee in the calculation of net
income or loss: (i) depreciation; (ii) amortization and other non-cash
charges; (iii) rent paid to Lessor in respect of the Lease; (iv) without
duplication of amounts described in the preceding clause (iii), interest
expense paid or accrued, including, without limitation, interest imputed on
leases which would, in accordance with GAAP, be classified as "capital
leases"; and (v) total federal and state income tax expense determined as the
accrued liability of Lessee in respect of such period, regardless of what
portion of such expense has actually been paid by Lessee during such period,
and AFTER DEDUCTION FOR each of (a) federal and state income taxes, to the
extent actually paid during such period; (b) any non-cash income (but only to
the extent such non-

                                   2

<PAGE>

cash income was included in the revenues of Lessee in the calculation of net
income or loss); and (c) all actual capital expenditures made by Lessee
during such period and not financed (with the qualification that all amounts
expended by Lessee pursuant to the Lease, if considered capital expenditures
under GAAP, shall be deemed financed for purposes of this definition).
"Contractual Debt Service" shall mean, for any period, the sum of payments
made (or, as to clauses (i) and (ii) of this sentence, required to be made)
by Lessee during such period for (i) scheduled payments of rent and any other
amounts due under the Lease, (ii) scheduled interest and principal payments
due on any and all outstanding indebtedness of Lessee, other than indebtedness
described in the following clause (iii), and (iii) interest and principal
payments made on any indebtedness of Lessee the repayment of which has been
subordinated to the payment of Lessee's obligations in respect of the Lease.

          2.  The Directors will not attempt to foreclose on any collateral
securing any part of the Director Debt until after such time as the FINOVA
Debt has been paid in full. Anything of value received by the Directors from
Lessee not in accordance with this Agreement shall be held by the Directors
in trust and immediately turned over to Lessor in the form received (with any
necessary endorsement attached or affixed thereto), to be applied by Lessor
to the FINOVA Debt.

          3.  Any time after the delivery by Lessor to the Directors of a
written notice of, and during the existence and continuance of, an Event of
Default, the Directors will not demand or accept from Lessee (and Lessee will
not make) any payment of all or any portion of the Director Debt. At such
time as an Event of Default, the result of which was to prohibit the Lessee
from making payments of the Director Debt, has been cured, all deferred
payments of the Director Debt which were otherwise payable during such time
may be paid to the Directors, PROVIDED that the payment of such amounts will
not result in Lessee's Debt Service Coverage Ratio falling below 1.0 to 1.0
or otherwise give rise to an Event of Default.

          4.  Until after such time as the FINOVA Debt has been paid in full,
the Directors will not (i) be a party to any action or proceeding against
Lessee to enforce payment of or on the Director Debt; (ii) exercise any
self-help remedies such as setoff or repossession with respect to any
property owned by Lessee; or (iii) foreclose (judicially or otherwise) any
lien on or security interest in real property, personalty or other collateral
with respect to any property owned by Lessee. Without limiting the generality
of the foregoing, until after such time as the FINOVA Debt is paid in full,
the Directors will not assert any claims in any insurance proceeds which may
be payable to Lessee and/or Lessor, and the Directors will not exercise (and
will, upon Lessor's request, specifically waive) any right (in their capacity
as the Directors hereunder) to participate in the negotiation or settlement
of any claim for insurance proceeds.

          5.  At any time and from time to time, without the Directors'
consent or notice to the Directors, and without liability to Lessor and
without impairing any of Lessor's rights against the Directors created
hereunder or any of the Directors' obligations hereunder,

                                    3

<PAGE>

Lessor may take additional or other security for the FINOVA Debt and may also
release, exchange, subordinate or relinquish any security for the FINOVA
Debt; release any person obligated on the FINOVA Debt; modify, amend or waive
compliance with any agreement relating to the FINOVA Debt; modify or amend the
conditions pursuant to which Distributions may be made by Lessee; increase
the amount of the FINOVA Debt; delay, omit, fail or refuse to take or
prosecute any action for collection of any FINOVA Debt or to foreclose upon
any collateral or take or prosecute any action on any agreement securing any
FINOVA Debt.

          6.  The Directors represent and warrant that the Director Debt is
not presently secured by any security interests, liens, or deeds of trust.
The Directors and Lessee agree that the Director Debt will not hereafter be
secured by any security interests, liens, or deeds of trust covering property
of the Lessee. The Directors hereby subordinate and make inferior any
security interests, liens, deeds of trust or other encumbrances now or
hereafter securing the Director Debt to all security interests, liens, and
other encumbrances covering property of the Lessee now or hereafter securing
the FINOVA Debt.

          7.  The Directors will notify Lessor at the address stated below
not less than ten (10) days before any assignment of the Director Debt and
will notify the Directors' assignee of the terms of this Agreement. Any
assignment of the Director Debt shall be subject to the condition that the
proposed assignee acknowledge and agree in writing to be bound by the terms
of this Agreement. Lessor's rights under this Agreement may be assigned in
connection with any assignment or transfer of any FINOVA Debt. This Agreement
is cumulative of all other rights, remedies, and security of Lessor. No
waiver by Lessor of any right under this Agreement shall affect or impair its
rights in any matters thereafter occurring.

          8.  The Directors shall pay Lessor's attorneys' fees and costs
(including expert witness fees) incurred in enforcing this Agreement whether
or not suit is brought, including any attorneys' fees and costs (including
expert witness fees) incurred by Lessor in proceeding under the Federal
Bankruptcy Code in order to collect any indebtedness hereunder.

          9.  This Agreement is binding upon and shall inure to the benefit
of the successors and permitted assigns of each of the parties to this
Agreement. The rights and interests of any assignee of any of the undersigned
shall be subject in all respects to the terms of this Agreement.

         10.  THIS AGREEMENT AND THE RIGHTS, DUTIES AND OBLIGATIONS OF THE
PARTIES THERETO SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
INTERNAL LAWS OF THE STATE OF ARIZONA AND TO THE EXTENT THEY PREEMPT THE LAWS
OF SUCH STATE, THE LAWS OF THE UNITED STATES.

3.0  RENT, OFFICE:

            Tenant shall pay to Landlord as rental for the full term hereof
     the sum of $57,504.00 dollars in lawful money of the United States, in
     monthly installments of $2,396.00 each, payable in advance on the first
     day of each calendar month of the term of this Lease (WITHOUT DEDUCTION,
     OFFSET, PRIOR NOTICE OR DEMAND), plus the amount of all excise taxes or
     other charges which may be levied by any government body on such
     rental or receipt thereof. The rent shall be paid at the address set out
     after the signature of Landlord in this Lease, or at such other place as
     Landlord shall direct. Rent for partial months shall be prorated.

            Receipt of the sum of $7,607.30 is hereby acknowledged by
     Landlord. Of said sum, $2,396.00 shall be attributed to the First
     Month's Rent (prorated), $239.60 to Port fees, $179.70 to CAM fees, when
     the term of this Lease commences and the balance is a Security Deposit.
     If Tenant shall pay all rent and observe and perform all of the terms,
     covenants and conditions of this Lease during the term, and all
     extensions and renewals thereof, Landlord will repay the Security
     Deposit to Tenant, without interest within ten (10) days after Tenant
     vacates the Premises. If Tenant defaults in any of the terms, covenants
     or conditions of this Lease (INCLUDING, BUT NOT LIMITED TO, NONPAYMENT
     OF RENT). Landlord may use or apply so much of the Security Deposit as
     is required to cure or make good such default, or to indemnify Landlord
     for loss or damage arising therefrom. Tenant agrees to restore Security
     Deposit to the full original amount immediately upon receipt of demand
     from Landlord therefor. The obligation to maintain the Security Deposit
     in the full original amount is a rental obligation under this Lease.

     3.1  OPTION PERIODS.  Tenant shall have the right to extend the term of
     this Lease for three (3) terms beyond the initial two (2) years, upon
     the terms and conditions set forth herein (singularly, "Extension
     Periods"). In the event Tenant elects to exercise the Extension Period,
     Tenant must give written notice to Landlord on or before OCTOBER 01,
     2000, OCTOBER 01, 2001 and OCTOBER 01, 2002 respectively. In the event
     Tenant elects to exercise the Extension Period, Annual Rental for the
     Premises shall be renegotiated between Tenant and Landlord on a "fair
     market value" basis.

     3.2  ASSIGNMENTS/ SUB-SUBLEASES.  In the event an assignment of Sublease
     is executed by Tenant the prior written consent of the Landlord and the
     SDUPD is required in each instance.

     3.3  OFFICE DEPOSIT(S).  "FIRST RIGHT OF REFUSAL" may be obtained in
     order to hold the space desired and to have first rights to that space.
     The equivalent of two months rent or $4,792.00 will be deposited with
     the Landlord with a letter of intent signed by both prospective Tenant
     and acknowledged by Landlord.

            "SECURITY DEPOSIT" Consists of two months rent or $4,792.00 and
     will be paid to Landlord on execution of this sublease. Two (2) months
     rent will be held as a total deposit for security for the duration of
     the tenancy. Deposit will be returned provided premises are returned to
     Landlord as they were received less normal depreciation. In the event
     Tenant has deposited fees for the first Right of Refusal, these fees
     will apply as the Security Deposit. Landlord will deduct from deposit
     $239.60 (1,198 sq. ft. @ $0.20 per sq. ft.) for cleaning of the carpet at
     end of lease.

     3.4  MISCELLANEOUS CHARGES.

            (a) Security Key Deposit: ($25.00 per key)

            Tenant is entitled to one (1) key per owner or employee. Broken
     keys may be replaced for a $10.00 fee. If Tenant loses a security key,
     Tenant may obtain a replacement key upon tender of an additional deposit
     of $25.00.

            (b) Utilities (Electrical Power), CAM (Common Area Maintenance)
     charges for office only.

     Tenant will be provided utility (electrical power) services from 8 AM to
     6 PM daily. Service at other times, including use by janitorial service,
     will be initiated by Tenant using a metered timer device in the suite.
     Real estate taxes (excepting taxes arising from Tenant's business) and
     insurance (other than specified in paragraph 14) shall be paid by
     Landlord. Utilities and CAM charges will be paid by the Tenant through a
     pro-rata assessment based on the SDG&E billings and CAM costs currently
     determined as $.15 per square foot of leased space. Square footage
     assessment will be reviewed on an annual basis to accurately reflect
     true costs.

4.0  POSSESSION:

            If Landlord is unable to deliver possession of the Premises to
     Tenant at the commencement of the term for any reason whatsoever, this
     Lease shall not be void or voidable for a period of ninety (90) days
     thereafter, nor shall Landlord be liable to Tenant for any loss or
     damage resulting therefrom, but the rent shall abate until Landlord
     delivers possession of the Premises to Tenant. The term of this Lease
     shall be extended for a period equal to any such delay and Tenant agrees
     to pay the rent provided for herein and to perform all of the terms and
     conditions of this Lease during such extension.

            If Landlord is unable to deliver possession of the Premises to
     Tenant within ninety (90) days after the commencement date, this Lease
     may be terminated by either Landlord or Tenant by written notice to the
     other at any time thereafter prior to the date possession is delivered
     to Tenant.

     services to be provided by Landlord shall be provided promptly and
     diligently, in a first-class, workmanlike manner.

     5.2  Tenant shall pay for goods and services, if any, specified in

     written approval of Landlord, all work on the Premises shall be done by
     contractors or other persons selected or employed by Landlord. Landlord

                       electricity for normal lighting and fractional
                       horsepower office machines and heat and air
                       conditioning required in Landlord's judgment for the
                       comfortable use and occupation of the Premises.

                       for a loss of or injury to property, however occurring,
                       through or in connection with or incidental to failure
                       to furnish any of the foregoing.  Whenever heat
                       generating machines or equipment are used in the
                       Premises which affect the temperature otherwise
                       maintained by the air conditioning system, Landlord
                       reserves the right to install supplementary air
                       conditioning units in the Premises and the cost
                       thereof, including the cost of the installation, and
                       the cost of the operation and maintenance thereof
                       shall be paid by Tenant to Landlord upon demand by
                       Landlord.

                             Tenant will not, without written consent of
                       Landlord, use any apparatus or device in the Premises,
                       including, but without limitation thereto, electronic
                       data processing machines, punch card machines, and
                       machines using in excess of 120 volts, which will in
                       any way increase the amount of electricity usually

                       general office space; nor connect with electric
                       current except through existing electrical outlets in
                       the Premises, any apparatus or device, for the purpose
                       of using electrical current.  If Tenant shall require
                       electric current in excess of that usually furnished
                       or supplied for the use of the Premises as general
                       office space, Tenant shall first procure the written
                       consent of Landlord, which Landlord may refuse, to the
                       use thereof and Landlord may cause an electrical
                       current meter to be installed in the Premises, so as
                       to measure the amount of electric current consumed for
                       any such use.  The cost of any such meters and of
                       installation, maintenance and repair thereof shall be
                       paid for by the Tenant and Tenant agrees to pay to
                       Landlord promptly upon demand therefor by Landlord for
                       all such electric current consumed as shown by said
                       meters, at the rates charged for such services by the
                       local public utility furnishing the same, plus any
                       additional expense insured in keeping account of the
                       electric current so consumed.  If a separate meter is
                       not installed, such excess cost for such electric
                       current will be established by an estimate made by a
                       utility company or electrical engineer.

           9.   ABANDONMENT:

                             Tenant will not vacate, abandon or surrender the

                       dispossessed by process of law, or otherwise, any
                       personal property belonging to Tenant left on the
                       premises shall be deemed to be abandoned at the option
                       of Landlord.

                             Tenant's taking possession shall be conclusive
                       evidence as against Tenant that the Premises were in
                       good order and satisfactory condition when Tenant took
                       possession.  No promise to alter, remodel or improve
                       the Premises or the Building and no representation
                       respecting the condition of the Premises or the
                       Building have been made by Landlord to Tenant, unless

     pay promptly the reasonable cost thereof. At any time or times,
     Landlord, either voluntarily or pursuant to governmental requirement,
     may, at Landlord's own expense, make repairs, alterations or
     improvements in or to the Building or any part thereof, including the
     Premises, and during such operations, Landlord may close entrances,

     the Premises and shall permit Landlord to post and record notices on
     non-responsibility (WHEN APPROPRIATE) within ten (10) days after the

          If Landlord's insurance rates for the premises are increased at any

     occupancy of the premises, Tenant agrees to reimburse Landlord for the
     full amount of such increase immediately upon receipt of demand from
     Landlord therefor.  Such increase shall be prorated as of the expiration
     of the term, if applicable.

     damage is covered by insurance maintained by the waiving party.

     covered under this Article occurs during the last twelve (12) months of
     the term of this Lease or any extension thereof.

     fire or other cause, or to make any repairs or replacements of any
     panels, decoration, office fixtures, railings, floor covering,

     and not before, the date when the possession of the part so taken shall
     be required for such use or purpose; provided, that at Landlord's option
     this Lease shall not terminate if Tenant's Premises are not taken and if
     Tenant's access to and use of its premises are not materially and
     detrimentally affected by the taking. Current rent shall be apportioned
     as of the date of such termination, but the entire award shall be the
     property of Landlord without apportionment.

30.  GENERAL PROVISIONS:

          30.1  This Lease contains all terms, covenants and conditions
     agreed to by Landlord and Tenant, and it may not be modified orally or
     in any manner other than by an agreement in writing signed by all the
     parties to this Lease or their respective successor in interest.

          Each term and each provision of this Lease performed by Tenant
     shall be construed to be both a covenant and a condition.

          The covenants and conditions hereof, subject to the provisions as
     to subletting and assignment, shall apply to and bind the heirs,
     successors, executors, administrators, Sublessee's and assigns of the
     parties.

          All persons who have signed this Lease shall be jointly and
     severally liable hereunder.

          When the context of the Lease requires, the masculine gender
     includes the feminine, a corporation or a partnership, and the singular
     number includes the plural.

          The captions of this Lease are for convenience only and are not a
     part of this Lease and do not in any way limit or amplify the terms and
     provisions of this Lease.

          This Lease shall be governed by and construed in accordance with
     the laws of the State of California.

          30.2  LATE CHARGES.  Tenant hereby acknowledges that late payment
     by Tenant to Landlord of rent or other sums due hereunder will cause
     Landlord to incur costs not contemplated by this Lease, the exact amount
     of which will be extremely difficult to ascertain. Such costs include,
     but are not limited to, processing and accounting charges, and late
     charges which may be imposed upon Landlord by terms of any mortgage or
     trust deed covering the Premises. Accordingly, if any installment of
     rent or a sum due from Tenant shall not be received by Landlord or
     Landlord's designee with five (5) days after said amount is due, the
     Tenant shall pay to Landlord a late charge equal to ten percent (10%) of
     such overdue Amount.  The parties hereby agree that such late charges
     represent a fair and reasonable estimate of the cost that Landlord will
     incur by reason of the late payment by Tenant. Acceptance of such late
     charges by the Landlord shall in no event constitute a waiver of
     Tenant's default with respect to such overdue amount, nor prevent
     Landlord from exercising any of the other rights and remedies granted
     hereunder.

          30.3 RULES AND REGULATIONS.  Tenant shall faithfully observe and
     comply with the rules and regulations that Landlord shall from time to
     time promulgate. Landlord reserves the right from time to time to make
     all reasonable

     forth. The adjustment factor shall adjust the Base Rent by the inflation
     measured by the Index and is defined as the quotient obtained by
     dividing the Base Index into the Current Index. In no event shall the
     adjustment entitle Tenant to received the benefit of a reduction of the
     Current Index below the level of the Base Index. Should the Bureau
     discontinue the publication of the above Index, or publish same less
     frequently, or alter same in some manner, then Landlord shall adopt a
     substitute index or substitute procedure which reasonably reflects and

                                 SECTION NINE
                           CONFIDENTIAL INFORMATION

         9.1. CONFIDENTIAL INFORMATION. During the period of time that the
Company has been in business, it has acquired, created and developed, and will
continue to acquire, create and develop certain confidential and proprietary
information, which the Executive has been and will continue to be exposed to,
and he has had and will continue to have an opportunity to learn about the
Company's customers (including records and information pertaining to its
customers and to the relationship between these customers and the Company),
operations, methods of doing business, research and development, know-how,
formulas, processes, trade secrets, computer programs, algorithms, finances
(including all non-public financial statements and information), and other
confidential and proprietary information belonging to the Company (collectively,
"Confidential Information"). The term, "Confidential Information," includes all
documents, materials, and information concerning the Company that are furnished,
made available, or otherwise disclosed to the Executive, except information that
was or becomes generally available to the public other than as a result of a
disclosure by or through the Executive. All such information is considered
secret and is disclosed to the Executive in Confidence.

         9.2. DISCLOSURE OF CONFIDENTIAL INFORMATION. Except as required in the
course of his employment by the Company, the Executive shall not directly or
indirectly disclose to any third person any of the Company's Confidential
Information without the Company's prior written consent. This covenant shall
survive the termination of this Agreement.

         9.3. UNFAIR COMPETITION. The Executive understands, acknowledges and
agrees that the Company is engaged in the business of providing and operating
mobile Positron Emission Tomography services in the United States, and is
expanding those services worldwide. For so long as the Executive is an
Executive of the Company, and for a period of 24 (twenty-four) months from
the date that he is no longer an Executive of the Company ( the "Restricted
Period"), the Executive agrees that he will not directly or indirectly
compete with the Company in the business of providing and operating mobile
Positron Emission Tomography services in the United States. As used in the
preceding sentence, "compete" means, but is not necessary limited to, the
Executive's engaging in or carrying on, either for himself or as an officer.
director, Executive, shareholder, partner, member, agent, associate,
consultant or affiliate of, or investor in any other person or entity that is
engaged in any activity described in the first sentence of this paragraph.
The Executive also agrees that for so long as the Executive is an Executive
of the Company and for the Restricted Period, he will not directly or
indirectly recruit, hire, assist others in recruiting or hiring, or refer to
others concerning employment, any person who is an Executive of the Company
or an affiliate of the Company. The provisions of this paragraph shall not
apply to the Executive if the Company terminates his employment or this
Agreement for any reason other than for one or more of the reasons set forth
in paragraph 8.1 above.

         9.4. EQUITABLE ENFORCEMENT. The Executive represents and agrees that
he finds the restrictions contained in sections 9.2 and 9.3 to be fair and
reasonable. He also understands,


                                     -6-

<PAGE>

acknowledges and agrees that if he were to breach any of his obligations
contained in sections 9.2 or 9.3, the Company would suffer immediate and
irreparable harm, and that an award of money damages would not be adequate to
fully compensate the Company for such harm. Accordingly, if the Executive
breaches or threatens to breach any of his obligations contained in
sections 9.2 or 9.3, the Company shall be entitled to a temporary restraining
order and a preliminary or temporary injunction, from any court having
jurisdiction, until the issue of such breach or threatened breach is finally
determined by arbitration pursuant to article ten. If such court determines
that it is reasonably likely that an arbitrator or arbitrator will find that
any of those obligations are not enforceable, in whole or in part, due to any
unreasonable restriction of duration, geographical area or activity, or any
combination thereof, such court shall nevertheless enjoin the breach thereof
as to such duration, geographical area and activity that the court determines
is fair and reasonable, pending arbitration proceedings to settle any
controversy or claim relating to the enforceability of the Executive's
obligations under sections 9.2 or 9.3. The court shall not require the
Company to post any bond or other surety as a condition to granting and
maintaining any temporary restraining order or preliminary injunction
pursuant to this paragraph 9.4.


                                  SECTION TEN
                              DISPUTE RESOLUTION

         10.1. BINDING ARBITRATION. Any controversy or claim arising out of or
relating to this Agreement, or a breach of this Agreement, shall be settled by
arbitration, at San Diego, California, in accordance with the Commercial
Arbitration Rules of the American Arbitration Association, before a panel of
three arbitrators, one appointed by each of the Company and the Executive, and
the third chosen by the two so appointed. The decision of the arbitrators shall
be final, and judgment on the award rendered by the arbitrator may be entered in
any court having jurisdiction. The prevailing shall be awarded reasonable
attorneys and arbitration costs.

         10.2. INTERIM RELIEF FROM A COURT. In additional to the interim
equitable enforcement provisions of paragraph 9.4, any party may request a court
to provide interim or provisional relief, and such request shall not be deemed
incompatible with this agreement to arbitrate or as a waiver of that agreement.

         10.3. EQUITABLE ENFORCEMENT. The parties acknowledge and agree that in
the event of a breach or threatened breach of this Agreement, or a party's
failure to perform any provision hereof to be performed by that party, damages
would be extremely difficult if not impossible to determine, and that the other
parties to this Agreement would not have any adequate remedy at law. The parties
agree that an arbitrator may grant injunctive relief and specific performance in
his or her award, and that any court having jurisdiction my enforce such
equitable relief.

         10.4. REFORMATION. In any arbitration proceedings relating to The
Executive's obligations under sections 9.2 or 9.3 above, if the arbitrators
should find that any of the restrictions contained in those paragraphs or any of
the Executive's obligations thereunder to be unenforceable, in whole


                                     -7-

<PAGE>

or in part, due to any unreasonable restriction of duration, geographical
area or activity, or any combination thereof, then the arbitrators shall have
the Executive's and the Company's express authority to reform those
restrictions and obligations to reasonable restrictions and obligations, and
to grant the Company any other legal or equitable relief reasonably necessary
to protect the Company's interest in its Confidential Information, and to

                             CONSULTING AGREEMENT

This Agreement is made and entered into this 15th day of December, 1998,
between Mobile PET Systems, Inc. (the "Company") and Northwest Capital
Partners, L.L.C. (the "Consultant"), and sets forth the terms and conditions
upon which the Consultant will act as financial advisor to the Company in
connection with the completion of the financing described in Exhibit "A"
attached hereto (the "Financing").

In consideration for the mutual promises and covenants contained herein, and
for other good and valuable consideration, receipt of which is hereby
acknowledged, the parties hereto agree as follows:

1.  PURPOSE. The Company hereby engages the Consultant during the term hereof
to arrange financing, as a finder, for the Company upon terms and conditions
as set forth herein and in accordance with the requirements set forth in
Exhibit "A" (the "Financing"). Consultant shall also have a right of first
refusal to consult with the Company regarding appropriate financings
subsequent to the Financings set forth in Exhibit "A" for a period of three
years following the term of this Agreement.

2.  TERM. The term of this Agreement shall be for a period of 36 months,
provided that the first Interim Financing shall be completed no later than
January 31, 1999. An offering pursuant to Rule 504 or other applicable Rule
adopted pursuant to the Securities Act of 1933, as amended (the "Act"), shall
be completed within 30 days of the Company's approval and, following the
quotation of the Company's common stock on the NASD OTC Bulletin Board and a
third round of financing, shall be completed within the 90 day period
following the date the Company's common stock is quoted on the NASD OTC
Bulletin Board.

3. DUTIES OF THE CONSULTANT. During the term hereof, Consultant shall provide
the Company with the benefit of its best judgment and efforts to complete the
Financing on a reasonable business basis in accordance with the requirements
set forth in Exhibit "A." It shall be Consultant's duty to suggest and
evaluate from the standpoint of financial soundness, the Company's business
plans and programs, corporate financial structures, and corporate
organization, and any other financial matters involving the Company. In
connection with the financing contemplated by this Agreement, Consultant
agrees that it will advise and work with the Company to complete the
Financing successfully in accordance with Rule 504 or other applicable Rule
under the Act and the related and applicable Blue Sky laws of the states in
which the financing is completed. Consultant shall advise the Company of each
proposed broker or other financing or referral source identified by
Consultant prior to authorizing any participation in the Financing.
Consultant shall use its best efforts, after receiving information from
Company sufficient to comply with the informational requirements of Rule
15c2-11 under the Securities Exchange Act of 1934 (the "1934 Act"), to
arrange for the shares of common stock of the Company to

                                        -1-
<PAGE>

be quoted on the NASD OTC Bulletin Board either by direct application and
approval through the NASD or by reverse merger. The Company and the
Consultant shall review the potential filing of a Form 10 (1934 Act form)
with the U.S. Securities and Exchange Commission following the Second Stage
Financing.  Company agrees that it will accept Financing amounts at each
closing contemplated by Exhibit "A" which are in excess of the amounts in
Exhibit "A" if Consultant is able to raise such additional amounts in
accordance with the appropriate disclosure and the securities registration
exemption provisions of the Act and the relevant Blue Sky laws. Consultant's
duties shall also include, but not be limited to:

      3.1  Assist the Company's management in the development and execution of
           a strategic short-term, intermediate term and long-term financial
           plan;

      3.2  Assist the Company in the negotiation of the terms of the
           Financings;

      3.3  Assist the management of the Company in connection with inquiries
           made by or on behalf of any proposed brokers and investors;

      3.4  Assist the management of the Company in the preparation of
           presentation materials for the purpose of pursuing the Financing;

      3.5  Using its best efforts, on terms acceptable to the Company, to
           arrange the Financings as described in Exhibit "A" attached hereto.

      3.6  If the Company and the Consultant determine that a direct
           application to the NASD is not in the best interest of the
           Company and determine that the Company go public by way of a
           reverse merger with an existing publicly traded company the
           Consultant will be responsible for the location and acquisition
           of such public company including all costs associated with its
           acquisition.

4.    CONSULTANT'S COMPENSATION.

      4.1  The Company shall pay Consultant a fee of $5,000 for each month or
           partial month this Agreement has been in effect, providing that
           such payment shall be paid, as accrued, at the closing of the
           Interim Financing and then continuing through the closing of the
           Second and Third Stage Financings, as described in Exhibit "A," by
           the Consultant. Upon the closing of the Third Stage of Financing,
           the fee of $5,000 per month will be extended for an additional 36
           months, for duties to be mutually agreed upon by the parties.

      4.2  The Company agrees that, at the closing of the first Interim
           Financing, as described in Exhibit "A," by the Consultant or at
           the time the Company goes public, the Company will issue to the
           Consultant

                                        -2-


<PAGE>

         1,200,000 shares of common stock of the Company at value of $0.01
         per share. The Consultant's shares shall be held in escrow by the
         Company's lawyer pursuant to an escrow agreement that releases the
         Consultant's shares to the Consultant based upon the following terms
         and conditions:

              Upon the completion of the Interim Financing, as described in
         Exhibit "A", the Consultant shall have earned 600,000 shares of the
         Company and such shares will be delivered to the Consultant. Upon
         the completion of the Second Stage Financing, as described in
         Exhibit "A", the Consultant shall have earned an additional 600,000
         shares of the Company and such shares will be delivered to the
         Consultant. Upon the Company's receipt of the aggregate amount of
         $1,000,000 through any combination of the Interim, Second or Third
         Stage financings as described in Exhibit "A", the Consultant shall
         have earned all 1,200,000 shares of the Company and such shares will
         be delivered to the Consultant. In the event that the Company
         terminates this agreement the Company retains the right to purchase
         all of the Consultant's shares that remain in escrow for $0.01 per
         share.

    4.3  The Company agrees to issue the Consultant an additional 1,000,000
         shares at a value of $0.01 per share if the Company's market
         capitalization achieves the value of $100,000,000.00 or more. These
         shares will be issued by the company as restricted shares at a value
         of $0.01 per share and will be granted "piggy-back" rights so that
         the shares will be registered upon the Company's first registration
         after the share's issuance.

    4.4  The Company agrees that it shall reimburse Consultant for
         reasonable, out-of-pocket expenses incurred by Consultant in
         performing the services provided pursuant to this Agreement,
         provided that such out-of-pocket expense reimbursement shall not
         exceed $3,000 in any calendar month or partial month, and provided
         that any expenses in excess of $500 in any calendar month shall
         require advance approval by the Company. Such reimbursement shall be
         paid upon the within 15 days of the Company's receipt of the
         Consultant's invoice. Such reimbursement may be claimed for any
         month commencing with the signing of this Agreement and monthly
         thereafter to the date of each closing, payable within 15 days of
         receipt.

    4.5  If the Consultant is unsuccessful in introducing investors to the
         Company (either directly or through a broker) who would be willing
         to fund the Financings contemplated in Exhibit "A" within the time
         periods set forth, this Agreement may be terminated at the Company's
         discretion, unless otherwise extended by mutual consent. Such consent

                                       -3-

<PAGE>

         will be implied should the Company be in or continue negotiation
         with investors which should reasonably result in successful
         Financing or should the Company accept funds from one of the sources
         introduced to the Company by the Consultant during this period.
         Following termination, however, Consultant will be entitled to the
         consideration above as to those stages of the Financing completed
         and in the event that after termination a financing of any kind or
         amount is consummated with any party introduced to the Company by
         the Consultant during a period of twelve months after termination of
         this Agreement.

5.  INDEMNIFICATION.

    5.1  The Company agrees to indemnify the Consultant, its agents and
         employees against any and all claims, lawsuits, and litigation
         arising from representations of the Company made to Consultant or
         prospective investors concerning its business plan and financial
         condition. Such indemnification shall include reasonable attorney's
         fees to defend any such actions or claims.

    5.2  The Consultant agrees to indemnify the Company, its agents and
         employees against any and all claims, lawsuits, and litigation
         arising from representations of the Consultant made to prospective
         investors concerning the Company except for those representations
         constituting information provided by the Company. Such
         indemnification shall include reasonable attorney's fees to defend
         any such actions or claims.

    5.3  Promptly after receipt by an indemnified party of notice of any
         claim or commencement of any action in respect of which indemnity
         may be sought, the indemnified party will notify the indemnifying
         party in writing of the receipt or commencement thereof and the
         indemnifying party shall have the right to assume the defense of any
         such claim or action (including the employment of counsel reasonably
         satisfactory to the indemnified party and the payment of fees and
         expenses of such counsel), after which the indemnifying party shall
         not be liable to the indemnified party for any legal fees incurred
         by the indemnified party in connection with the defense of such
         claim or action. Notwithstanding the prior sentence, the indemnified
         party shall have the right to control its defense if, in the opinion
         of it counsel, the indemnified party's defense is unique or separate
         to it, as the case may be, as opposed to a defense pertaining to the
         indemnifying party. In such event, the indemnified party shall have
         the right to retain counsel reasonably satisfactory to the
         indemnifying party at the indemnifying party's expense, to represent
         it in any claim or action in respect of which indemnity may be
         sought and agrees to cooperate with the indemnifying party and the
         indemnifying party's counsel on the defense of any such

                                       -4-

<PAGE>

         claim of action, it being understood, however, that the indemnifying
         party shall not, in connection with any such claim or action or
         separate but substantially similar or related claim or action in the
         same jurisdiction arising out of the same general circumstances, be
         liable for the reasonable fees and expenses of more than one
         separate firm of attorneys, unless the defense of one indemnified
         party is unique or separate from that of another indemnified party
         subject to the same claim or action. No party shall be liable for
         any settlement of any claim or action effected without its written
         consent.

6.  REPRESENTATION AND WARRANTIES. Company represents and warrants as follows:

    6.1  The Company has been duly incorporated and is validly existing as a

                                                                EXHIBIT 10.17

                            MOBILE PET SYSTEMS, INC.

                             1999 STOCK OPTION PLAN


         SECTION 1. PURPOSE. The purpose of this 1999 Stock Option Plan (the
"PLAN") is to enable Mobile PET Systems, Inc., (the "COMPANY") to attract and
retain the services of people with training, experience and ability, and to
provide additional incentive to such persons by granting them an opportunity to
participate in the ownership of the Company.

         SECTION 2. STOCK SUBJECT TO PLAN. The stock subject to this Plan shall
be the Company's common stock, $.01 par value per share (the "COMMON STOCK")
presently authorized but unissued. The aggregate amount of Common Stock reserved
for issuance or delivery upon exercise of all options granted under this Plan
shall not exceed 1,000,000 shares of Common Stock, subject to adjustment
pursuant to Section 10 below. If any option granted under this Plan shall expire
or terminate for any reason without having been exercised in full, the
unpurchased shares subject thereto shall be returned to the Plan and become
available for future grant under the Plan.

         SECTION 3. ADMINISTRATION. The Plan shall be administered by the Board
of Directors of the Company or any committee of the Board of Directors delegated
such authority pursuant to Section 3.3 (the "PLAN ADMINISTRATOR"), in accordance
with the following terms and conditions:

                  3.1 GENERAL AUTHORITY. Subject to the express provisions of
the Plan, the Plan Administrator shall have the authority, in its sole
discretion, to determine all matters relating to options granted under the Plan,
including, without limitation, the selection of individuals to be granted
options, the number of shares to be subject to each option, the fair market
value of the shares and the exercise price, the term, whether such options shall
be immediately exercisable or shall become exercisable in increments over time,
and all other terms and conditions thereof, and to make all other determinations
necessary or advisable in the administration of the Plan. Grants under this Plan
to persons eligible need not be identical in any respect, even when made
simultaneously. The Plan Administrator may from time to time adopt, amend and
rescind rules and regulations relating to the administration of the Plan. The
interpretation and construction by the Plan Administrator of any terms or
provisions of this Plan or any option issued hereunder, or of any rule or
regulation promulgated in connection herewith shall be conclusive and binding on
all interested parties. The Plan Administrator in its sole discretion may grant
incentive stock options ("INCENTIVE STOCK OPTIONS") as such term is defined in
Section 422(b) of the Internal Revenue Code of 1986, as amended (the "CODE"),
and/or nonqualified stock options ("NONQUALIFIED STOCK OPTIONS"). A Nonqualified
Stock Option is a stock option, which is not an Incentive Stock Option. The term
"OPTION" when used in this Plan refers to Incentive Stock Options and
Nonqualified Stock Options, collectively.

                  3.2 DIRECTORS. A member of the Board of Directors may be
eligible to participate in or receive or hold options under this Plan; provided,
however, that no member of the Board of Directors shall vote with respect to the
granting of an option hereunder to himself or herself.

                  3.3 DELEGATION TO A COMMITTEE. The Board of Directors, if it
so determines, may delegate to one or more committees of the Board of Directors
(each consisting of not less than two members of the Board of Directors) any or
all authority for the administration of the Plan, subject to such terms and
conditions the Board of Directors may prescribe. If, and so long as, the Company
has a class of equity securities registered under Section 12 of the Securities
Exchange Act of 1934, as amended (the

                                     -1-
<PAGE>

"EXCHANGE ACT"), the Board of Directors in determining the membership of any
such committee shall, with respect to option grants to any persons subject to
or likely to become subject to Section 16 of the Exchange Act, give due
consideration to the provisions regarding (a) "outside directors" as
contemplated by Section 162(m) of the Code and (b) "nonemployee directors" as
contemplated by Rule 16b-3 under the Exchange Act. Thereafter references to
the Plan Administrator in this Plan shall be deemed to be references to such
committee to the extent such authority is so delegated.

                  3.4 REPLACEMENT OF OPTIONS. Without limiting the authority
granted to the Plan Administrator under Section 3.1, the Plan Administrator, in
its sole discretion, shall have the authority, among other things, to (a) grant
options subject to the condition that options previously granted at a higher or
lower exercise price under the Plan be canceled or exchanged in connection with
such grant (the number of shares covered by the new options, the exercise price,
the term and the other terms and conditions of the new option, shall be
determined in accordance with the Plan and may be different from the provisions
of the canceled or exchanged options), and (b) amend or modify outstanding and
unexercised options, with the consent of the holder of the option, to, among
other things, reduce the exercise price per share, establish the exercise price
at the then-current fair market value of the Common Stock or accelerate or defer
the exercise date, vesting schedule or expiration date of any option.

                  3.5 LOANS TO OPTIONEES. The Plan Administrator, in its sole
discretion, may provide that the Company loan to any Optionee sufficient funds
to exercise any option granted under the Plan and/or to pay withholding tax due
upon exercise of such option. The Plan Administrator shall have the authority to
make such determinations at the time of grant or exercise and shall establish
repayment terms thereof, including installments, maturity, interest rate and
security for repayment.

         SECTION 4. ELIGIBILITY. Options may be granted only to persons who, at
the time the option is granted, are employees, directors, consultants or
advisors of the Company or any of its then-existing parent or subsidiary
corporations (hereafter a "PARENT" or "SUBSIDIARY"). Any person to whom an
option is granted under this Plan shall be referred to hereinafter as
"OPTIONEE." Any Optionee may receive one or more grants of options as the Plan
Administrator shall from time to time determine, and such determinations may be
different as to different Optionees and may vary as to different grants.
Optionees who are not employees will only be eligible to receive Nonqualified
Stock Options. An "employee" shall be any person, including officers and
directors, employed by the Company or any Parent or Subsidiary, with the status
of employment determined based upon such minimum number of hours or periods
worked as shall be determined by the Board of Directors in its discretion,
subject to any requirements of the Code.

         SECTION 5. TERMS AND CONDITIONS OF OPTIONS. Options granted under this
Plan shall be evidenced by written agreements which shall contain such terms,
conditions, limitations and restrictions as the Plan Administrator shall deem
advisable and which are not inconsistent with this Plan. Each option agreement
shall clearly indicate whether the option granted thereby is an Incentive Stock
Option or a Nonqualified Stock Option. Notwithstanding the foregoing, all such
options shall include or incorporate by reference the following terms and
conditions:

                  5.1 NUMBER OF SHARES AND EXERCISE PRICE. The maximum number of
shares that may be purchased pursuant to the exercise of each option and the
price per share at which such option is exercisable (the "EXERCISE PRICE") shall
be as established by the Plan Administrator, provided that the exercise price
for any Incentive Stock Option shall not be less than the fair market value per
share of the Common Stock at the time the option is granted and subject further
to Section 7.2 below. The exercise

                                     -2-
<PAGE>

price of Nonqualified Stock Options may be less than, equal to or greater
than the fair market value per share of the Common Stock at the time the
option is granted.

                  a. LIMITATION ON NUMBER OF SHARES UNDERLYING OPTIONS. Subject
to adjustment from time to time as provided in Section 10 below, the Plan
Administrator shall not grant options to any person in any one fiscal year of
the Company in an amount that exceeds, in the aggregate, [250,000] shares of
Common Stock. This limitation shall be applied in a manner consistent with the
requirements of, and only to the extent required for compliance with, the
exclusion from the limitation on deductibility of compensation under Section
162(m) of the Code.

                  b. DETERMINATION OF FAIR MARKET VALUE. For the purposes of
this Plan, fair market value of Common Stock, as of any date, shall be
determined as follows:

                  (i) If the Common Stock is listed on any established stock
         exchange or a national market system, including without limitation The
         Nasdaq National Market, its fair market value shall be the closing
         sales price for such stock (or the closing bid, if no sales were
         reported), as quoted on such system or exchange, or the system or
         exchange with the greatest volume of trading in Common Stock, for the
         last market trading day prior to the time of determination, as reported
         in The Wall Street Journal or such other source as the Plan
         Administrator deems reliable;

                  (ii) If the Common Stock is quoted on The Nasdaq SmallCap
         Market, on the over-the-counter system, or regularly quoted by a
         recognized securities dealer but selling prices are not reported, its
         fair market value shall be the last trade reported for the Common Stock
         on the last market trading day prior to the time of determination, as
         reported in The Wall Street Journal or such other source as the Plan
         Administrator deems reliable; or

                  (iii) In the absence of an established market for the Common
         Stock, the fair market value thereof shall be determined in good faith
         by the Plan Administrator.

                  5.2 DURATION OF OPTIONS. Subject to the restrictions contained
in Section 9, the term of each option shall be established by the Plan
Administrator and, if not so established, shall be ten years from the date it is
granted, but in no event shall the term of any Incentive Stock Option exceed ten
years.

                  5.3 EXERCISABILITY. Each option shall prescribe the
installments or vesting schedule, if any, under which an option granted under
the Plan shall become exercisable. In the absence of a defined vesting schedule
in an option agreement, the option covered by such agreement shall vest annually
over four years from the date of grant, at the rate of 25 percent per year on
each anniversary of the date of grant. The Plan Administrator, in its absolute
discretion, may waive or accelerate any vesting requirement contained in
outstanding and unexercised options. Only whole shares shall be issued pursuant
to the exercise of any option.

         SECTION 6.        RESTRICTIONS ON TRANSFERABILITY

                  6.1 Options granted under this Plan and the rights and
privileges conferred hereby shall not be subject to execution, attachment or
similar process and may not be assigned, alienated, pledged, sold, or
transferred in any manner (whether by operation of law or otherwise) other than
by will or by the laws of descent and distribution.

                                     -3-
<PAGE>

                  6.2 Notwithstanding Section 6.1 above, in the case of a
Nonqualified Stock Option, an Optionee may transfer such option either (a)
pursuant to a "domestic relations order" as defined in Section 414 of the Code
or Section 206 of the Employment Retirement Income Security Act, or the rules
thereunder, or (b) by transfer without the receipt of consideration by an
Optionee, subject to such rules as the Plan Administrator may adopt to preserve
the purposes of the Plan (including limiting such transfers to transfers by
Optionees who are directors or senior executives), to

                  (i) a member of his or her Immediate Family or, in the case of
         an Optionee that is a corporation, partnership or limited liability
         company, holders of equity ownership interest of Optionee;

                  (ii) a trust solely for the benefit of the Optionee and/or
         his or her Immediate Family, or

                  (iii) a partnership, corporation or limited liability company
         whose only partners, shareholders or members are the Optionee and/or
         (y) his or her Immediate Family members or (z) holders of equity
         ownership interest of Optionee (in the case of an Optionee that is a
         corporation, partnership or limited liability company).

(each transferee described in 6.2(a) and (b) is hereafter referred to as a
"PERMITTED TRANSFEREE"), provided that the Plan Administrator is notified in
advance in writing of the terms and conditions of any proposed transfer
described in (a) or (b) and it determines that the proposed transfer complies
with the requirements of the Plan and the applicable option agreement. For this
purpose, "Immediate Family" means, with respect to a particular Optionee, the
Optionee's spouse, children and grandchildren (including adopted and
stepchildren and grandchildren).

                  6.3 Upon any attempt to transfer, assign, pledge, hypothecate
or otherwise dispose of an option granted under the Plan or any right or
privilege conferred hereunder contrary to the provisions of the Plan, or upon
the sale, levy or any attachment or similar process upon the rights and
privileges conferred by an option granted under the Plan, the option shall
thereupon terminate and become null and void.

                  6.4 The terms of options granted under this Plan and
transferred in accordance with this Section 6 shall apply to the beneficiaries,
executors and administrators of the Optionee and of the Permitted Transferees of
the Optionee (including the beneficiaries, executors and administrators of the
Permitted Transferees), including the right to agree to any amendment of the
applicable option agreement, except that Permitted Transferees shall not
transfer any option other than by will or by the laws of descent and
distribution.

                  6.5 Options granted under this Plan, or options transferred in
accordance with this Section 6, are exercisable during Optionee's lifetime only
by Optionee or Permitted Transferee, as applicable (or his or her attorney in
fact or guardian). In the event of the death of an Optionee or Permitted
Transferee, options may be exercised by such Optionee's or Permitted
Transferee's executor or administrator. In no event shall the Company issue
shares of Common Stock upon exercise of an option unless Optionee or Permitted
Transferee makes sufficient payment, as determined by the Company, to meet
withholding tax obligations on such exercise or other arrangements satisfactory
to the Plan Administrator to provide for such payment.

                                     -4-

       SECTION 7. CERTAIN LIMITATIONS REGARDING INCENTIVE STOCK OPTIONS. The
grant of Incentive Stock Options shall be subject to the following special
limitations:

                  7.1 LIMITATION ON AMOUNT OF GRANTS. To the extent that an
Optionee is granted Incentive Stock Options that in the aggregate (together with
all other Incentive Stock Options granted by the Company or any Parents or
Subsidiaries) entitle the Optionee to purchase, in any calendar year during
which such options first become exercisable, stock of the Company, any Parent or
any Subsidiary having a fair market value (determined as of the time such
options are granted) in excess of $100,000, such options in excess of the
$100,000 threshold shall be treated as Nonqualified Stock Options. No limitation
shall apply to Nonqualified Stock Options.

                  7.2 GRANTS TO TEN PERCENT SHAREHOLDERS. Incentive Stock
Options may be granted to a person who, at the time the option is granted, owns
more than ten percent of the total combined voting power of all classes of stock
of the Company and any Parent or Subsidiary only if (i) the exercise price is at
least 110 percent of the fair market value of the Common Stock at the time of
grant, and (ii) the option is not exercisable more than five years from the date
of grant.

                  7.3 TAXATION OF INCENTIVE STOCK OPTIONS. In order to obtain
certain tax benefits afforded to Incentive Stock Options under Section 422 of
the Code, the Optionee must hold the shares issued upon the exercise of an
Incentive Stock Option for a minimum of two years after the date of grant of the
Incentive Stock Option and one year from the date of exercise. An Optionee may
be subject to the alternative minimum tax at the time of exercise of an
Incentive Stock Option. The Plan Administrator may provide in any option
agreement evidencing an Incentive Stock Option granted under this Plan that the
Optionee under such agreement be required to give the Company prompt notice of
any subsequent disposition of shares acquired on exercise of such Incentive
Stock Option prior to the expiration of the above holding periods.

       SECTION 8. EXERCISE OF OPTIONS. Options shall be exercised in accordance
with the following terms and conditions:

                  8.1 PROCEDURE. Options shall be exercised by delivery to the
Company of written notice of the number of shares with respect to which the
option is exercised.

                  8.2 PAYMENT. Payment of the exercise price shall be made in
full within five business days of the notice of exercise of the option and shall
be in cash or bank-certified, cashier's or personal check. If the Company's
Common Stock is registered under Section 12 of the Exchange Act, then, to the
extent permitted by applicable laws and regulations (including, but not limited
to, federal tax and securities laws and regulations) and unless the Plan
Administrator determines otherwise, an option also may be exercised by (a)
delivery of shares of Common Stock of the Company that have been held by the
Optionee for at least six months having a fair market value equal to the
exercise price, such fair market value to be determined in good faith by the
Plan Administrator (such payment in stock may occur in the context of a single
exercise of an option or successive and simultaneous exercises, sometimes
referred to as "pyramiding," which provides that, rather than physically
exchanging certificates for a series of exercises, bookkeeping entries will be
made pursuant to which the Optionee is permitted to retain his existing stock
certificate and a new stock certificate is issued for the net shares), or (b)
delivery of a properly executed exercise notice together with irrevocable
instructions to (i) a broker to promptly deliver to the Company the amount of
sale or loan proceeds to pay the exercise price and any withholding tax
obligations that may arise in connection with such exercise, and (ii) the
Company to

                                     -5-
<PAGE>

deliver the certificates for such purchased shares directly to such broker,
all in accordance with the requirements of the Federal Reserve Board.

         In addition, the exercise price for shares purchased under an option
may be paid, either singly or in combination with one or more of the alternative
forms of payment authorized by this Section 8.2, by (y) a promissory note
delivered pursuant to Section 3.5 or (z) such other consideration as the Plan
Administrator may permit.

                  8.3 RIGHTS AS SHAREHOLDER. Until the issuance (as evidenced by
the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company) of the stock certificate evidencing such shares,
no right to vote or receive dividends or any other rights as a shareholder shall
exist with respect to the shares acquired on exercise, notwithstanding the
exercise of the option. The Company shall issue (or cause to be issued) such
stock certificate promptly upon exercise of the option and payment of the
exercise price. In the event that the exercise of an option is treated in part
as the exercise of a Nonqualified Stock Option pursuant to Section 7.2, the
Company shall issue a stock certificate evidencing the shares treated as
acquired upon the exercise of an Incentive Stock Option and a separate stock
certificate evidencing the shares treated as acquired upon the exercise of a
Nonqualified Stock Option, and shall identify each such certificate accordingly
in its stock transfer records. No adjustment will be made for a dividend or
other right for which the record date is prior to the date the stock certificate
is issued, except as provided in Section 10 of this Plan.

                  8.4 FEDERAL WITHHOLDING TAX REQUIREMENTS. Upon exercise of an
option, the Optionee shall, upon notification of the amount due and prior to or
concurrently with the delivery of the certificates representing the shares, pay
to the Company amounts necessary to satisfy applicable federal, state and local
withholding tax requirements or shall otherwise make arrangements satisfactory
to the Company for such requirements. If permitted by the Plan Administrator,
such arrangements may include payment of the appropriate withholding tax in
shares of stock of the Company having a fair market value equal to such
withholding tax, either through delivery of shares held by the Optionee or by
reduction in the number of shares to be delivered to the Optionee upon exercise
of such option.

         SECTION 9. TERMINATION OF EMPLOYMENT, DISABILITY AND DEATH

                  9.1 GENERAL. If the employment of the Optionee by the Company,
a Parent or a Subsidiary shall terminate by retirement or for any reason other
than death or disability (as hereinafter provided), the option may be exercised
by the Optionee, or its Permitted Transferee, at any time prior to the
expiration of three months after the date of such termination of employment
(unless by its terms the option sooner terminates or expires), but only if and
to the extent the Optionee was entitled to exercise the option at the date of
such termination.

                  9.2 DISABILITY. If the employment of the Optionee by the
Company, a Parent or a Subsidiary is terminated because of the Optionee's
disability (as herein defined), the option may be exercised by the Optionee, or
its Permitted Transferee, at any time prior to the expiration of one year after
the date of such termination (unless by its terms the option sooner terminates
or expires), but only if and to the extent the Optionee, or its Permitted
Transferee, was entitled to exercise the option at the date of such termination.
For purposes of this section, an Optionee will be considered to be disabled if
the Optionee is unable to engage in any substantial gainful activity by reason
of any medically determinable mental or physical impairment which can be
expected to result in death or which has lasted or can be expected to last for a
continuous period of not less than 12 months.

                                     -6-
<PAGE>

                  9.3 DEATH. In the event of the death of an Optionee while in
the employ of the Company, a Parent or a Subsidiary, the option shall be
exercisable on or prior to the expiration of one year after the date of such
death (unless by its terms the option sooner terminates and expires), but only
if and to the extent the Optionee was entitled to exercise the option at the
date of such death and only by the Optionee's personal representative if then
subject to administration as part of the Optionee's estate, or by the person or
persons to whom such Optionee's rights under the option shall have passed by the
Optionee's will or by the applicable laws of descent and distribution or by
Optionee's Permitted Transferee.

                  9.4 WAIVER OR EXTENSION OF TIME PERIODS. The Plan
Administrator shall have the authority, prior to or within the times specified
in this Section 9 for the exercise of any such option, to extend such time
period or waive in its entirety any such time period to the extent that such
time period expires prior to the expiration of the term of such option. In
addition, the Plan Administrator may modify or eliminate the time periods
specified in this Section 9 with respect to particular option grants. However,
no Incentive Stock Option may be exercised after the expiration of ten years
from the date such option is granted. If an Optionee holding an Incentive Stock
Option exercises such option, by permission of the Plan Administrator, after the
expiration of the time periods specified in this Section 9, the option will no
longer be treated as an Incentive Stock Option under the Code and shall
automatically be converted into a Nonqualified Stock Option.

                  9.5 TERMINATION OF OPTIONS. To the extent that the option of
any deceased Optionee or of any Optionee whose employment is terminated shall
not have been exercised within the limited periods prescribed in this Section 9,
all further rights to purchase shares pursuant to such option shall cease and
terminate at the expiration of such period.

                  9.6 NON-EMPLOYEE OPTIONEES. Options granted to Optionees who
are not employees of the Company, a Parent or a Subsidiary at the time of grant
shall not be subject to the provisions of this Section 9, except as specifically
provided in the written option agreement for such Optionee.

         SECTION 10.  OPTION ADJUSTMENTS

                  10.1 ADJUSTMENTS UPON CHANGES IN CAPITALIZATION. The aggregate
number and class of shares on which options may be granted under this Plan, the
number and class of shares covered by each outstanding option and the exercise
price per share thereof (but not the total price), and all such options, shall
each be proportionately adjusted for any increase or decrease in the number of
issued shares of Common Stock of the Company resulting from a stock split,
reverse stock split, stock dividend, combination or reclassification or any like
capital adjustment, or any other increase or decrease in the number of shares of
Common Stock of the Company without the receipt of consideration by the Company.

                  10.2 EFFECT OF CERTAIN TRANSACTIONS. Except as otherwise
provided in the option agreement, in the event of a merger, consolidation,
disposition of all or substantially all of the assets, separation,
reorganization or liquidation of the Company, as a result of which the
shareholders of the Company receive cash, stock or other property in exchange
for their shares of Common Stock, or upon the acquisition by a person (as
defined in Section 3(a)(9) and 13(d)(3) of the Exchange Act as in effective as
of the date hereof) of a majority of the Company's outstanding voting securities
(whether directly or indirectly, beneficially or of record) (each, a "Corporate
Transaction"), all outstanding and unexercised options granted under this Plan
shall automatically accelerate so that each option shall, immediately prior to
any such Corporate Transaction, become 100 percent vested (except that such

                                     -7-
<PAGE>

acceleration shall not occur if, in the opinion of the Company's accountants,
such acceleration would render unavailable "pooling of interest" accounting for
a Corporate Transaction that would otherwise qualify for such accounting
treatment). Provided further, however, that an option shall not so accelerate if
and to the extent that such option is, in connection with a Corporate
Transaction, either to be assumed by the successor corporation or its parent or
to be replaced with a comparable option for the purchase of shares of capital
stock of such successor corporation or its parent. Immediately following the
consummation of any Corporate Transaction, all options shall terminate and cease
to remain outstanding, except to the extent assumed by a successor corporation.
Any such options that are assumed or replaced in a Corporate Transaction and do
not otherwise accelerate at that time shall be accelerated in the event the
Optionee's employment or services should subsequently terminate within two years
following such transaction.

                  10.3 FURTHER ADJUSTMENT OF OPTIONS. The Plan Administrator
shall have the discretion, exercisable at any time before a sale, merger,
consolidation, reorganization, liquidation or change in control of the Company,
as defined by the Plan Administrator, to take such further action as it
determines to be necessary or advisable, and fair and equitable to Optionees,
with respect to options. Such authorized action may include (but shall not be
limited to) establishing, amending or waiving the type, terms, conditions or
duration of, or restrictions on, options so as to provide for earlier, later,
extended or additional time for exercise and other modifications, and the Plan
Administrator may take such actions with respect to all Optionees, to certain
categories of Optionees or only to individual Optionees. The Plan Administrator
may take such action before or after granting options to which the action
relates and before or after any public announcement with respect to such, sale,
merger, consolidation, reorganization, liquidation or change in control that is
the reason for such action.

                  10.4 FRACTIONAL SHARES. In the event of any adjustment in the
number of shares covered by any option, any fractional shares resulting from
such adjustment shall be disregarded and each such option shall cover only the
number of full shares resulting from such adjustment.

                  10.5 DETERMINATION OF PLAN ADMINISTRATOR TO BE FINAL. All
adjustments made pursuant to this Section 10 shall be made by the Plan
Administrator and its determination as to what adjustments shall be made, and
the extent thereof, shall be final, binding and conclusive.

         SECTION 11.  SECURITIES REGULATIONS

                  11.1 COMPLIANCE. Shares shall not be issued with respect to an
option granted under this Plan unless the exercise of such option and the
issuance and delivery of such shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, any applicable state
securities laws, the Securities Act of 1933, as amended, the Exchange Act, the
rules and regulations promulgated thereunder, and the requirements of any stock
exchange, national market system, over the counter system, or any electronic
bulletin board, upon which the shares may then be listed, quoted or traded, and
shall further be subject to the approval of counsel for the Company with respect
to such compliance. Inability of the Company to obtain from any regulatory body
having jurisdiction the authority deemed by the Company's counsel to be
necessary for the lawful issuance and sale of any shares hereunder shall relieve
the Company of any liability in respect of the nonissuance or sale of such
shares as to which such requisite authority shall not have been obtained.

                  11.2 REPRESENTATIONS BY OPTIONEE. As a condition to the
exercise of an option, the Company may require the Optionee to represent and
warrant at the time of any such exercise that the shares are being purchased
only for investment and without any present intention to sell or distribute

                                     -8-
<PAGE>

such shares, if, in the opinion of counsel for the Company, such
representation is required by any relevant provision of the laws referred to
in Section 11.1 above. At the option of the Company, a stop transfer order
against any shares of stock may be placed on the official stock books and
records of the Company, and a legend indicating that the stock may not be
pledged, sold or otherwise transferred unless an opinion of counsel was
provided (concurred in by counsel for the Company) stating that such transfer
is not in violation of any applicable law or regulation, may be stamped on
the stock certificate in order to assure exemption from registration. The
Plan Administrator may also require such other action or agreement by the
Optionees as may from time to time be necessary to comply with the federal
and state securities laws. This provision shall not obligate the Company to
undertake registration of options or stock hereunder.

         SECTION 12. EMPLOYMENT RIGHTS. Nothing in this Plan or any option or
right granted pursuant hereto shall confer upon any Optionee any right to be
continued in the employment of the Company, a Parent or any Subsidiary of the
Company, or to remain a director thereof or a consultant thereto, or to
interfere in anyway with the right of the Company, a Parent or any Subsidiary,
in its sole discretion, to terminate such Optionee's employment at any time or
to remove the Optionee as a director or consultant at any time.

         SECTION 13.  AMENDMENT AND TERMINATION

                  13.1 ACTION BY SHAREHOLDERS. The Plan may be terminated,
modified or amended by the shareholders of the Company.

                  13.2 ACTION BY BOARD OF DIRECTORS. The Board of Directors may
also terminate the Plan, or modify or amend the Plan in such respects as it
shall deem advisable in order to conform to any changes in law or regulation
applicable thereto, or in other respects; provided, however, that, to the extent
required for compliance with Section 422 of the Code or any applicable law or
regulation, the Board of Directors may not, without further approval by the
shareholders of the Company:

                           (i) Change the number of shares in the aggregate, as
         to which options may be granted under the Plan;

                           (ii) Change the eligibility of persons to be granted
         Incentive Stock Options under the Plan;

                           (iii) Change the terms of the Plan which causes the
         Plan to lose its qualification as an incentive stock option plan under
         Section 422(b) of the Code; or

                           (iv) Otherwise amend the Plan for which shareholder
         approved is required under any applicable law or regulation.

                  No termination, suspension or amendment of the Plan may,
without the consent of each Optionee to whom any option shall previously have
been granted, adversely affect the rights of such Optionees under such options.

                  13.3 AUTOMATIC TERMINATION. Unless the Plan shall have been
terminated as herein provided, this Plan shall terminate ten years from the
earlier of: (i) the date on which the Plan is adopted by the Board of Directors;
or (ii) the date on which this Plan is approved by the shareholders of the
Company. No option may be granted after such termination, or during any
suspension of this Plan. The


                                     -9-
<PAGE>

amendment or termination of this Plan shall not, without the consent of the
Optionee, alter or impair any rights or obligations under any option
previously granted under this Plan.

         SECTION 14. EFFECTIVE DATE OF THE PLAN. This Plan shall become
effective on the date of its adoption by the Board of Directors of the Company
and options may be granted immediately thereafter, but no option may be
exercised under the Plan unless and until the Plan shall have been approved by
the shareholders within 12 months after the date of adoption of the Plan by the
Board of Directors. If such approval is not obtained within such period the Plan
and any options granted shall be null and void.

         ADOPTED BY THE BOARD OF DIRECTORS ON DECEMBER 15, 1998; APPROVED BY THE
COMPANY'S SHAREHOLDERS ON DECEMBER 15, 1998.
