PART I

Item 1. Description of Business.

General

     CLIXhealth.com, Inc., a Nevada corporation, ("CLIX" or the "Company") is a
holding Company with two wholly owned subsidiaries, Cardiovascular Laboratories,
Inc. of PA, a Pennsylvania corporation ("CLI"), and CLIX Information Systems,
Inc., a Pennsylvania corporation, doing business under the name VitalBody
("VitalBody"). In April 1999, the Company changed its name from Cardiovascular
Laboratories, Inc. to CLIXhealth.com, Inc. in order to reflect the new focus of
the Company in the e-commerce marketplace for preventive health care products.
All of the Company's 1997 and 1998 revenues were provided by CLI.

     CLI specializes in the provision of non-invasive cardiovascular imaging and
the turnkey management of fixed site vascular and echocardiographic ultrasound
laboratories. CLI provides services with the highest clinical quality possible,
and strives to maintain those clinical standards. CLI has historically focused
on fixed- site imaging within community hospitals, although it currently
operates in, and intends to expand into additional independent fixed-site
imaging locations as well as into new community hospitals. CLI does not
presently perform mobile imaging services. It presently operates eleven
diagnostic imaging sites in ten fixed-site locations in Pennsylvania, New Jersey
and New York. At its locations, CLI performs a scope of services that can
include one or more of the following: hiring, training and clinical management
of ultrasound technologists; management and administration of laboratory
operations; and selection, leasing and deployment of ultrasound equipment.

     VitalBody was incorporated in May 1998, and is a development stage
enterprise engaged in Internet-based sales of preventive health care products.
VitalBody has yet to generate more than nominal revenues from its activities. It
was formed to diversify the Company's source of revenue and profits. VitalBody's
principal objective is to create branded lines of "wellness" products sold
through interactive e-commerce and direct marketing. Brand awareness is to be
created through sponsorship provided by association with authoritative experts
who have an existing media presence, by aligning with existing and prospective
Internet retailers and by creating joint ventures and other programs to support
the overall marketing and sales effort.

Historical Background

     The Company was originally incorporated in Utah on August 8, 1983 as
Interstate Gold and Gas, Inc. The Company was in a development stage from
inception until 1992, engaged in the business of developing mining properties.
During 1992, the Company lost its remaining mining claims, and became inactive.
The Company remained inactive until March 31, 1998, when it acquired CLI. CLI
was incorporated in August 1991, and has been engaged in the provision of
non-invasive ultrasound diagnostic services since inception. Following the
acquisition of CLI, the name of the Company was changed to Cardiovascular
Laboratories, Inc., and the former management and Board of CLI assumed effective
control of the Company. In April 1999, the Company changed its name from
Cardiovascular Laboratories, Inc. to CLIXhealth.com, Inc.

Cardiovascular Laboratories, Inc. of PA

Market

     Cardiovascular disease is responsible for nearly half of all deaths in the
United States. The aging process itself predisposes human beings to
cardiovascular disease. Approximately 65% of CLI's patients are covered by
Medicare, with the balance having commercial insurance or being included in a
managed care contract. According to the National Center for Health Statistics,
there are over 67 million people with some form of cardiac or vascular disease
in the United States. Cardiovascular disease can often be effectively treated if
detected early. Diagnostic ultrasound is the most cost effective, least painful
and least invasive method available for diagnosing vascular disease. It produces
no side effects. CLI believes its imaging revenues are not subject to the ebb
and flow of the economic cycle. CLI estimates that its core ultrasound imaging
marketplace generated approximately $2.5 billion in 1997 revenues, and expects
demand to increase at 8% per year as the population ages.

Diagnostic Ultrasound Imaging

     Diagnostic ultrasound imaging helps doctors see inside the human body by
bouncing sound waves off of anatomy and blood flow. It works without the use of
dyes, injections, or catheters. These sound waves are received by the ultrasound
machine, interpreted by sophisticated imaging software and displayed on a video
monitor. The test results are captured on a videotape machine built into the
unit. After the technical component of the

                                        3

<PAGE>

diagnostic test has been performed by a technologist, an interpreting physician
views the videotape and establishes test findings. Although most competing
diagnostic imaging techniques provide the physician a frozen-in-time snapshot
image, ultrasound imaging enables the diagnostician to study real-time blood
flow non-invasively. A dynamic tool, it allows the physician to make more
accurate diagnoses at earlier stages of the disease. This increases the
possibility of successful treatment.

     Diagnostic ultrasound testing is broken into two components: technical and
professional. The technical component is the technologist's use of the
ultrasound equipment within strict clinical protocols, recording the visual and
auditory information onto videotape. The professional component consists of an
experienced physician reading the videotape, making a diagnosis of the patient's
condition, and dictating the diagnosis into a formal interpretation. The
critical difference in the two components is that the technologist does not
practice medicine, but performs a service for the physician who does practice
medicine.

Low Exposure to Malpractice

     Because CLI does not practice medicine, or perform any invasive procedures,
CLI believes it carries a relatively low exposure to malpractice liability. Even
so, CLI insures its and its employee's exposure by coverage from the nation's
leading medical malpractice insurer. Since inception, neither CLI nor any of its
employees have been sued for professional negligence.

Testing Process

     The testing process begins when a patient's physician orders a test and
refers the patient to one of CLI's labs. A specially trained and registered
technologist performs the test according to rigorously disciplined protocols
using sophisticated equipment, costing approximately $150,000 to $200,000 per
unit. Tests are then interpreted by an interpreting physician and a course of
treatment can be prescribed.

Ultrasound is a Well Established Diagnostic Imaging Technology

     Ultrasound is a well accepted diagnostic tool for assessing the progression
of cardiovascular disease. As a dynamic medium using simple sound waves,
ultrasound technology is uniquely suited for the diagnoses of cardiovascular
disease. It offers important advantages in cost effectiveness over other
diagnostic methods.

                                        4

<PAGE>

Despite advances in other imaging areas, ultrasound is likely to continue to be
an important diagnostic modality due to advances in hardware, software, and the
prospective use of ultrasound in conjunction with non-toxic contrast agents. The
Company believes that these advances, plus the inherent non-invasive nature of
ultrasound make its obsolescence as a diagnostic modality unlikely in the near
future.

Studies Performed

     An example of a study performed by CLI is a cerebrovascular test. This
procedure examines blood flow to the brain to detect conditions which could lead
to stroke. The diagnosing physician uses the data produced by the technologist
to find plaque or stenosis in the carotid artery. This is a powerful and cost
effective first step to preventing stroke. As the United States population ages
(and age predisposes people to vascular disease) cerebrovascular tests will be
performed more frequently.

     The most common cardiovascular imaging studies performed by CLI
include:

     o  Cerebrovascular evaluation
     o  Transcranial doppler procedures
     o  Lower arterial studies
     o  Lower venous studies
     o  Echocardiography
     o  Abdominal aorta studies
     o  Dialysis access site assessment
     o  Visceral vascular studies
     o  Graft surveillance
     o  Venous mapping

Emphasis On Clinical Quality

     CLI is dedicated to the delivery of a superior level of quality in all of
its diagnostic testing. CLI concentrates on high-end ultrasound diagnostics,
providing tests that are usually available only through university hospitals in
major metropolitan centers. CLI insists on employing strict protocols and
self-policing auditing methods, which require technologists to spend more time
evaluating patients than current industry standards dictate. When the
comprehensive nature of these testing protocols are coupled with highly trained
technologists, diagnostic accuracy is measurably improved. And, when
sophisticated tests are executed with painstaking care, they become more cost
effective in

                                        5

<PAGE>

diagnosing disease at an early stage, thereby reducing the cost of treatment.

Clinical Training Program

     Cardiovascular ultrasound is a diagnostic imaging modality that is highly
dependent on the training and experience of the technologist performing the
procedure. Unlike many other types of diagnostic imaging, the technologist must
act as a clinician, and not merely the operator of a machine. This places a
premium on the technologist's skills. Historically, CLI has recruited its
technologists through contacts it has in the technologist community as well as
through the use of professional medical recruiting services. However, CLI is
embarking on a program to align itself with a world-class cardiovascular
ultrasound educational institution to create a more assured source for training
technologists, and remove one constraint to growing the business.

     Additionally, as CLI expands its operations into new areas, with new
interpreting physicians, it will become more difficult to maintain
interpretations at the consistently high level of clinical quality it has come
to expect in the past. Accordingly, discussions have begun with prominent
educational institutions in diagnostic ultrasound to form an alliance to help
train new interpreting physicians and provide an ongoing program of clinical
quality assurance.

Business Strategy

     Historically, CLI has concentrated on operation of imaging labs within
community hospitals. The Company currently has six such hospital contracts to
operate imaging facilities on-site. These contracts range from a full turn-key
management of an entire lab to the provision of specialized personnel to perform
diagnostic imaging within the hospital's own lab. These services benefit a
hospital by expanding the scope of services, increasing outpatient referrals,
creating positive cash flow and increasing surgery and ancillary procedures. CLI
gives the hospital access to a higher quality pool of technologists than might
otherwise be possible because it can hire, train and compensate its employees
without the institutional personnel constraints present in many hospitals.
Hospitals have a built-in source of referrals and thus a predictably high level
of volume. CLI invoices hospitals directly for imaging services. Hospital
receivables are generally easier to manage than receivables owed directly to CLI
from Medicare carriers and other insurers.

                                        6

<PAGE>

     In addition to hospital-based locations, CLI operates several
independently-owned site labs. Independently sited locations perform services
independently from a hospital, and invoice insurance carriers for studies
through an entity known as an Independent Diagnostic Testing Facility ("IDTF").
The Company is responsible for establishing clinical protocols and maintaining
quality control, leasing and maintaining equipment, hiring, training and
employing technologists, scheduling patients and general lab administration, and
billing and collection activity.

     CLI believes that there will be opportunities to expand the hospital-based
business during the next few years. The Health care Financing and Health
Administration (HCFA), the financing arm of the federal Medicare program, has
announced that it intends to establish a new prospective payment system for
hospital outpatient services. This new payment system is similar to the
Diagnosis Related Group payment methodology introduced in 1984 for hospital
inpatient services. The new outpatient payment system will classify payments
into fixed Ambulatory Patient Groups (APG's). This development represents a
significant change in the way outpatient health care services are delivered, and
it is currently unclear whether CLI will be able to profit from such changes. It
is possible that existing hospital contracts will require re-structure and
modification in such a way that the profitability of the business is adversely
impacted.

Changing Regulations in Ultrasound Imaging

     Beginning in 1999, Medicare carriers and intermediaries in many states,
(including Pennsylvania and New Jersey) are scheduled to stop reimbursing
vascular ultrasound imaging service providers who either provide services in a
lab that has not met the stringent accreditation standards set forth by the
Intersocietal Commission for the Accreditation of Vascular Laboratories
("ICAVL"), or provide services that are not performed or directly supervised by
a Registered Vascular Technologist ("RVT").

     CLI estimates that fewer than 40% of vascular laboratories currently comply
with ICAVL accreditation standards. The reason for this non-compliance centers
on the level of training of the average technologist and the level of diligence
and sophistication of the average laboratory. CLI has always operated as if
ICAVL standards were in effect. All of CLI's technologists are Registered
Vascular Technologist (or registry eligible). All of its facilities currently
meet, or in the case of new labs, are on track to meet the new ICAVL standards.

                                        7

<PAGE>

     There may be additional changes in regulations that have a material
negative impact on the imaging business as currently performed by CLI. These
changes may have to do with the acceptable means of structuring relationships
with hospitals and physicians, or there may be adverse changes in the
reimbursement regulations that govern CLI's operations.

Technology

     CLI uses laboratory imaging and other equipment supplied by a number of
different equipment manufacturers. The equipment is typically acquired on an
operating lease basis, and CLI believes it will be able to upgrade its fleet of
diagnostic machines on an as-needed basis to accommodate new technology as it
becomes available.

     Notwithstanding the belief that the Company will be able to upgrade its
equipment on an as-needed basis, CLI does enter into multi-year lease agreements
that may not be able to be modified should new technology emerge.

Competition

     CLI faces substantial competition in its imaging business from numerous
competitors. The most significant competitor is usually the community hospital
within CLI's immediate market areas. The facilities operated by these hospitals
vary widely in terms of the quality and training of their personnel, equipment
and clinical protocols. Notwithstanding these potential negative attributes,
however, it is often difficult to compete with established patterns of medicine
evident between a hospital's lab and the physicians who practice in that
hospital and refer patients into the lab.

     Other competition comes from physicians and group practices of physicians
who have set up ultrasound diagnostic imaging capabilities within their own
practices. While these imaging locations may have some of the same drawbacks
presented by the hospital labs, the physicians who operate their own labs will
not refer any of their patients to a CLI lab.

     CLI competes with hospital-based and physician practice-based labs by
offering a superior clinical service, and by being a non-aligned third party
provider of services that is not necessarily affiliated with either a hospital
or a specific physician.

     Additionally, CLI faced significant competition during 1998 from a company
formed by its former Chief Executive Officer who

                                        8

<PAGE>

resigned in November 1997. This competition was successful in causing the loss
of four contracts maintained by the Company. Together, these contracts accounted
for annualized revenue of approximately $2,000,000. While the Company was able
to expand existing operations to mitigate the overall impact of the loss of
these hospital contracts, it lost a significant number of trained employees to
this competitor.

Seasonality

     CLI's results of operations may vary significantly from quarter to quarter,
for reasons particular to each quarter. For instance, hospital admissions and
doctor visits (and, therefore, CLI's imaging revenues) are typically lower
during holiday periods, and at other times when physicians traditionally take
their own vacations.

Suppliers

     Although CLI has historically acquired most of its imaging and related
equipment from a small number of suppliers, CLI does not believe it is dependent
upon any one supplier or group of suppliers. While CLI has a preference for the
equipment manufactured by certain manufacturers, there are a number of
manufacturers of imaging equipment adequate for CLI's purposes, and an even
greater number of companies from whom such equipment can be leased. CLI believes
that alternate sources for its equipment and supply needs are readily available
at comparable costs, and that its relationships with its equipment suppliers are
satisfactory.

Patents Or Trademarks

     Although CLI relies upon sophisticated equipment, instrumentation and
technology, CLI does not own, license or otherwise rely upon any patents or
trademarks for the operation of its business. Other than corporate names, CLI
does not own or utilize any trade names in its business.

Governmental Regulation

     Many aspects of the health care industry in the United States are presently
subject to extensive federal and state governmental regulation. Certain of these
laws and regulations are applicable to CLI's business. CLI believes that its
operations are in material compliance with all applicable laws.


                                        9

<PAGE>

Federal Kickback Law

     Federal law prohibits the offer, solicitation, payment or receipt of any
remuneration (direct or indirect, overt or covert, in cash or in kind) which is
intended to induce, or is in return for, the referral of patients for, or the
ordering of, items or services reimbursable by Medicare or Medicaid. The law
also prohibits remuneration intended to induce the purchasing of, or arranging
for, or recommending the purchase or order of any item, good, facility or
service for which payment may be in whole or in part under those programs. Under
this statute, known as the "kickback law," an offense may be punished by
criminal prosecution or by excluding any of the parties to the transaction or
arrangement from participation in Medicare and Medicaid. The law is very broad
and has been interpreted to apply to otherwise legitimate investment interests
if one purpose of the offer of an opportunity to invest is to induce referrals
from the investors. Regulations implemented under the kickback law provide
certain "safe harbors" giving protection for certain categories of
relationships. The breadth of the kickback law is such that virtually any
financial relationship between a practitioner and a health care provider, such
as an independent physiological laboratory (IPL) or an independent diagnostic
testing facility (IDTF), involving the offering of Medicare and Medicaid
services may trigger the application of the law. A portion of CLI's business
arrangements involves the management and staffing of in-house diagnostic
laboratories at hospitals. CLI does not bill Medicare or Medicaid for the
technical services provided at the hospitals' laboratories and is in compliance
with the Federal kickback law.

Federal Stark Laws

     Federal law also prohibits physicians from ordering or prescribing certain
designated health care services or items if the service or item is reimbursable
by Medicare or Medicaid and is provided by an entity with which the physician
has a financial relationship (including investment interests and compensation
arrangements). Payment for a service provided in violation of these laws, known
as the "Stark Laws," may be denied, or money paid may be recouped. The services
specified by the Stark Laws include ultrasound procedures and other designated
services, which are provided by CLI as the result of referrals from physicians
who purchase the tests from CLI. CLI believes that its relationships with
referring physicians are in compliance with the Stark Laws. A number of states,
including states in which CLI does business, have laws and regulations similar
to the federal kickback laws and

                                       10

<PAGE>

Stark Laws. CLI believes that it is in compliance with all of such laws,
although, as is the case with federal law, there can be no assurance that
changes in such laws or the interpretation or enforcement of such laws will not
have a material effect on CLI.

IDTFs

     CLI must satisfy certain rules set forth by the Health Care Financing
Administration ("HCFA") relating to the payment of services to Medicare or
Medicaid beneficiaries. These rules state that the carriers will pay for
services under the Medicare fee schedule only when performed by a physician, a
group practice of physicians, an approved supplier of portable x-ray services,
or an IDTF. The current effective date for IDTF status is March 15, 1999. CLI
believes that its services provided outside of the hospital environment are
provided according to the rules and specifications of an IDTF.

Potential National Health Care Reform

     Both the Clinton Administration and the Congress have periodically asserted
a need to overhaul or reform the nation's health care system. Such legislative
initiatives, if enacted, could impose pressures on the pricing structures
applicable to CLI's services. In particular, there is a possibility that an even
greater portion of health care services will be rendered and administered
through "managed care" systems, which could have the effect of forcing pricing
concessions and reductions on the part of service providers such as CLI.
Moreover, health care reform could also entail a greater analysis of each
patient's need for diagnostic testing, with the aim of reducing the total volume
of testing and the overall cost of medical care. CLI is unable to predict
whether, when or to what extent any new laws or regulations may be enacted, or
existing laws or regulations may be modified, any of which could have a material
adverse effect on CLI's revenues, operating margins and profitability.

Environmental Matters

     CLI's existing operations do not entail the handling, storage, use,
transport or disposal of any hazardous substances or hazardous materials within
the meaning of any environmental laws. Should CLI enter into nuclear cardiology
imaging services, it will be required to implement a radioactive waste disposal
program consistent with state and federal regulations. In this event, CLI
intends to contract with a nuclear medicine physicist to develop a full

                                       11

<PAGE>

compliance program for the proper handling and disposal of any waste generated
in the performance of nuclear cardiology studies.

Year 2000 Compliance

     CLI recognizes the need to ensure that its operations will not be adversely
impacted by Year 2000 computer and systems failures. Year 2000 failures due to
processing errors potentially arising from calculations using the Year 2000 date
are a known risk. CLI is addressing this risk to the availability and integrity
of financial systems and the reliability of operational systems. During the
first quarter of 1999, CLI upgraded its internal accounting and administrative
computer hardware and software. CLI believes that its administrative computer
systems are now sufficiently compliant with year 2000 compatibility issues, and
that any incompatibility will be able to be managed at a nominal cost and have
minimal potential to adversely impact the business. To date, the year 2000
compliance issues have generated little or no cost to CLI.

     It is possible that third party vendor software may pose unanticipated
incompatibilities that are not presently under consideration, and there may be
unanticipated negative consequences to the operations and administration of
CLI's business. It is not possible to quantify these uncertainties, nor the
potential for disruption of CLI's business. CLI has consulted with its
diagnostic equipment vendors and has been advised that certain items will be
supported at no cost, and that older items will be supported on a fee basis. CLI
believes that all of the equipment it uses in a clinical setting will be able to
be upgraded at nominal cost and without a material impact to the operations of
the business.

     Certain of the CLI's customers and vendors may be dependent on year 2000
non-compliant computer or other embedded information systems to conduct business
transactions. Although CLI has undertaken certain steps to determine the nature
or extent of any Year 2000 issues that may be posed by customer or vendor
unpreparedness, CLI cannot be sure that its customers or vendors will not cause
interruptions in CLI's business. In particular, the systems of the hospitals and
physicians with whom CLI does business may not be fully compliant with year 2000
compatibility. Moreover, there can be no assurance that such systems will not
interfere with the ability of the hospitals to pay CLI for its services, either
through direct or indirect problems caused by year 2000 incompatibility.

     CLI cannot be certain that the operations of private insurance

                                       12

<PAGE>

companies, health maintenance organizations, Medicare, and other third party
payers will not adversely effect CLI's business because of year 2000
incompatibilities. It is possible that one or more third-party payer will face
serious disruption to its business as a consequence of unanticipated year 2000
compliance problems. If this happens, CLI may be deprived of cash flows due for
its services, and may not have the financial resources or have access to the
financial resources to support its operations, with potentially serious
ramifications for the survival of the business, depending on how long it took
for the incompatibility problems to be resolved.

VitalBody

The Market

     VitalBody is a development stage business formed in May 1998 to sell
products and services using the Internet and by other, more traditional channels
to customers in the health care market. This market is both large and diverse
and includes numerous subsets including, but not limited to, nutritional
supplements, exercise equipment and videos, books, magazines, health clubs and
resort spas. VitalBody has selected nutritional supplements as its initial
target market.

     Nutritional supplements consist of vitamins, minerals, herbs and sports
supplements. According to the Nutrition Business Journal, vitamins are the
largest category of nutritional supplements, with 43% of 1997 sales, while herbs
held 33% of 1997 sales. Herbs are the fastest growing segment of the market, and
the industry has been adept at finding and promoting new herbal products
aggressively. According to the Nutrition Business Journal, in 1997, there were
four main distribution channels: retail; mail order; multi-level marketing
(sometimes referred to as direct sales or network sales); and health
practitioners.

     During 1998, the Internet emerged as a distribution channel. Although
figures are not available for on-line sales of supplements, a few relatively
well established firms have staked out territory including Vitamin Shoppe,
Mother's Nature, GreenTree and VitaSave. These companies have augmented their
existing mail order and retail store business by going on-line. The largest
domestic retail supplement chain, General Nutrition Centers, has not yet
established a significant presence on-line, perhaps over a potential concern for
cannibalizing their existing retail storefronts.

                                       13

<PAGE>

     According to the Nutrition Business Journal, national surveys estimate that
54% of Americans take some sort of nutritional supplements. An estimated 25
million Americans consume supplements regularly, with approximately 2.5 million
people spending over $50 per month, with the remaining 22.5 million spending
approximately $20-$25 per month. Increasing awareness of the health benefits of
nutritional supplements caused both the number of regular consumers to increase.
Information concerning herbal-based supplements has also pushed up the average
purchase per month, as these herbal preparations are often more expensive than
more conventional vitamins and minerals.

Business Strategy

     In 1998, the Company made a strategic decision to enter into the
Internet-based wellness and preventive health care market, initially by means of
selling nutritional supplements and other products and services through its
VitalBody subsidiary in conjunction with joint venture partners. The intention
is to diversify the Company's business and to provide a new source of revenue
and profitability. It is currently in a development stage, and there can be no
assurance that it will develop significant revenues or profits in the future.

     In February 1999, VitalBody entered into a sales and marketing agreement
with Global Connections, Inc., an e-commerce sales and technology firm. Pursuant
thereto, Global Connections has agreed to design and maintain a number of
e-commerce web sites with VitalBody joint venture partners; establish and
maintain secure e-commerce capabilities, including the facility for processing
credit cards; manage shipping and warehousing; and provide sales support
services including the maintenance of direct marketing databases and staffing an
800 number for customer service. The agreement provides that Global Connections
will receive a fixed percentage of the gross margins earned from products sold.
The agreement has a five year term.

     The initial product line introduced by VitalBody is in the area of
nutritional supplements. In March 1999, VitalBody entered into an agreement with
The National Anti-Aging Institute ("NAAI") located in Los Angeles, California.
NAAI is headed by its Medical Director, Arnold Fox, MD, a cardiologist who, for
the past 20 years, has had an alternative medicine practice. Dr. Fox has
published nine books on alternative medicine, several of them best-sellers. He
also has a weekly radio show broadcast on a FM station in Los Angeles. The
agreement provides that VitalBody and the NAAI

                                       14

<PAGE>

shall work together to establish a line of nutritional supplements. Among
other provisions, the agreement calls for the use of the radio show to promote
an e-commerce site established for the purpose of selling nutritional supplement
products. VitalBody intends to attempt to expand Dr. Fox's radio presence into
other markets to further promote the e-commerce site. The agreement provides
that NAAI shall receive a fixed percentage of any net revenues generated from
products sold. The agreement provides that the Company is responsible for
marketing, manufacture, and development of all products, including operating and
maintaining an e-commerce site. The agreement has a five year term.

     VitalBody intends to add value to its products through innovative
marketing, and custom formulations. The NAAI is the initial partner for the
intended commercialization of a line of 40 to 50 nutritional supplements and 5
to 10 custom formulations. In this fashion, products quickly obtain a level of
credibility that would otherwise be difficult to achieve. VitalBody launched its
first e-commerce site May 1999. The web address for the primary e-commerce site
that VitalBody manages for the NAAI is: http://www.theanti-aginginstitute.com.

     Subsequent contracts with joint venture partners other than the NAAI are
anticipated. None of these additional prospective agreements have been
finalized, and it is possible that none of the agreements will ultimately be
consummated.

     Few Internet-based businesses are profitable, and there is no assurance
that VitalBody will be able to grow either its revenues or derive profitability
from what revenues are generated. The Company is in the process of testing its
marketing strategies, and has not generated significant sales revenues to date.
It is possible that the development stage business undertaken by VitalBody will
change its focus several times in the future in the search for a successful
sales and marketing approach. There is no assurance that any of these approaches
will actually produce revenues and profits.

Governmental Regulation and Legal Uncertainties

     The Federal Trade Commission (FTC) and the Food and Drug Administration
(FDA) have complementary jurisdiction to address the marketing of dietary
supplements broadly governed by the framework of the Dietary Supplement Health
and Education Act of 1994 (DSHEA). Under the terms of a liaison agreement
governing the division of responsibilities between the two agencies, the FTC has
primary

                                       15

<PAGE>

responsibility for advertising and the FDA has primary responsibility for
labeling. Under a liaison agreement between the two agencies, they work closely
in regulating the industry.

     The market for nutritional supplements has grown rapidly since the passage
of the Dietary Supplements and Health Education Act of 1994 (known as DSHEA)
that largely deregulated sale of these products. While nutritional supplements
are still subject to labeling requirements, and may make certain benefit claims
only when there is research to support the claim, the FDA does not require
formal approval prior to sale of these products.

     The DSHEA legislation established a new regulatory framework for
supplements, ensuring continued access to safe products that are made to quality
standards. DSHEA essentially deregulated the nutritional supplement business.
This stands in sharp contrast to the regulatory environment that exists in
CLIX's imaging division. DSHEA also allowed for the dissemination of information
about the health benefits of these products. The legislation defined dietary
supplements; established a framework for ensuring safety; provided for use of
claims and nutritional support statements; required ingredient and labeling
requirements; provided for good manufacturing processes; and established new
governmental entities for review and research.

     One of the critical distinctions made by DSHEA has to do with product
claims. No claim can be made about the use of supplements to diagnose, prevent,
mitigate or cure specific diseases except under very specific circumstances.
However, the legislation does permit so-called structure-function claims. For
example, one may not claim the calcium prevents osteoporosis. However, one may
claim that calcium builds strong bones.

     In the past, the FDA attempted to define supplements as drugs or as food
additives and as a result often removed them from the market. The DSHEA
legislation makes it clear that supplement products may not be regulated as
drugs or food additives in most cases. While the FDA still maintains the
authority to remove products they deem dangerous, they are required to do so
only after careful evaluation and consideration.

     Claims made in supplement advertising are addressed primarily under the
Federal Trade Commission Act (FTC Act). Section 5 of the FTC Act broadly
prohibits deceptive and unfair acts or practices in or affecting commerce,
including deceptive advertising. In addition, supplement advertising falls under
Sections 12 and 15 of

                                       16

<PAGE>

the FTC Act. These two sections prohibit false advertisements of foods, drugs,
devices, services and cosmetics, which are defined as advertisements that are
misleading in a material respect The FTC has developed a legal framework for
assessing advertising claims pursuant to these provisions. This framework, set
out in the FTC's Deception Policy Statement and its Substantiation Policy
Statement, can be distilled into two principles: advertising must be truthful
and not misleading; and advertisers must have substantiation for all objective
claims before the claims are disseminated.

Competition

     The markets for VitalBody's nutritional products are intensely competitive.
Many of VitalBody's competitors have much greater name recognition and financial
resources than the Company, which may give them a competitive advantage. There
can be no assurance that the Company's business and results of operations will
not be affected materially by market conditions and competition in the future.

     Although the Company intends to distribute certain products it considers
proprietary, neither it nor NAAI have patent protection for any current or
planned products. Because of restrictions under regulatory requirements
concerning claims that can be made with respect to dietary supplements, the
Company may have a difficult time differentiating its products from those of
competitors.

     There is no assurance that the joint venture marketing strategy in
conjunction with existing media figures will prove successful. Neither can there
be any assurance that VitalBody will be able to successfully establish other
joint venture arrangements with new joint venture partners. Moreover, the
Internet is an unknown distribution channel, and its future is inherently
unpredictable. Currently there are numerous e-commerce sites selling nutritional
supplements over the Internet. Many of these sites are believed to have limited
traffic. However, a number of these sites have well-developed customer bases,
and offer substantially larger product lines than VitalBody.

Suppliers

     VitalBody has identified several manufacturers who will serve as the
initial suppliers for the product to be sold in its joint venture with the NAAI.
These suppliers have been selected for the price, quality and range of their
product offerings. Should any one of these suppliers not be able to satisfy
VitalBody's requirements,

                                       17

<PAGE>

it is not anticipated to be difficult to find alternate manufacturers to supply
products at competitive prices. However, there can be no assurance that
VitalBody will be able to find alternate suppliers in the event its currently
selected suppliers are unable to provide product at attractive prices, high
quality and favorable delivery terms.

Employees

     As of July 31, 1999, CLIX had an aggregate of 22 full-time employees. Of
such employees, one is an employee of CLIX and the remainder are employees of
CLI.

Overview

     CLIXhealth.com, Inc. (formerly Cardiovascular Laboratories,

                                       18

<PAGE>

Inc.) has two subsidiaries, Cardiovascular Laboratories, Inc. of PA("CLI"),
and CLIX Information Services, Inc. (doing business under the name of
VitalBody). All of the revenue generated by CLIX during fiscal years 1997 and
1998 came from CLI. VitalBody did not commence operations until May 1999 and has
not generated any meaningful revenues as of July 31, 1999. CLIX is not an
operating entity, and does not generate operating revenues.

Results Of Operations

Years ended December 31, 1997 and December 31, 1998

     Revenues. Revenues were $3,404,460 for the year ended December 31, 1997 and
$3,327,216 million for the year ended December 31, 1998. The slight decrease in
revenues resulted from the loss of revenue from certain hospital contracts. In
this regard, during 1998 and 1999, CLI lost four such contracts to a competitive
organization formed by CLI's former Chief Executive Officer. The lost revenues
amounted to approximately $2,000,000 on an annualized basis. However, the
Company was able to open new locations and recoup approximately one-half of the
lost revenue. Despite an increase in the number of studies performed in
accordance with hospital contracts, fees received from certain hospitals were
lower in 1998 than in 1997.

     Salaries, Payroll Taxes and Employee Benefits. Salaries, payroll taxes and
employee benefits were $1,651,326 for the year ended December 31, 1997 and
$1,587,527 for the year ended December 31, 1998. The reduction was due to a
smaller workforce, primarily in administrative personnel.

     Equipment Leasing and Laboratory Costs. Equipment leasing and laboratory
costs were $716,260 for the year ended December 31, 1997 and $902,030 for the
year ended December 31, 1998. The increase in machine lease and laboratory costs
was due to an expansion of the CLI hospital-based laboratory business during the
last two months of 1997, which resulted in additional laboratory costs for
ultrasound supplies, parts and service for the ultrasound equipment, and
additional ultrasound machines.

     Consulting and Professional Fees. Consulting and professional fees costs
were $534,620 for the year ended December 31, 1997 and $500,876 for the year
ended December 31, 1998. The reduction in fees was due to the elimination of
certain consulting arrangements during 1998.


                                       19

<PAGE>

     Administrative and Other Expenses. Administrative and other expenses were
$354,637 for the year ended December 31, 1997 and $323,337 for the year ended
December 31, 1998. The decrease was due to various measures taken by management
during 1998 to manage the administration of the business more effectively than
during 1997.

     Rent and Occupancy Costs. Rent and occupancy costs were $106,138 for the
year ended December 31, 1997 and $135,980 for the year ended December 31, 1998.
The increase was due to moving the corporate headquarters during 1998 while
sub-letting the previous corporate headquarters space at a price that was less
than the entire amount of the lease payment due.

     Depreciation. Depreciation expenses were $32,935 for the year ended
December 31, 1997 and $23,028 for the year ended December 31, 1998. The decrease
was due to the sale of depreciable assets.

     Interest. Interest expenses were $23,248 for the year ended December 31,
1997 and $35,379 for the year ended December 31, 1998. The increase was due to
an increase in the amount of borrowing undertaken by CLI during 1998.

     Non Recurring Expenses. The $240,360 in nonrecurring expenses incurred
during 1998 were due to the former Chief Executive Officer of CLI organizing a
company to compete with CLI after he resigned from the Company in November 1997.
This former executive induced the resignation of multiple technical and
administrative personnel of CLI. In order to perform its obligations under the
terms of certain of CLI's hospital contracts, CLI was required to pay remaining
employees overtime and bonuses plus travel expenses to service the contracts,
hire technical personnel on a temporary basis to service the contracts, recruit
additional technical staff to service the contracts and pay the attendant legal
and personnel-related expenses incurred during this process.

     Net Gain (Loss). During 1997, the Company lost $3,700 and during 1998 the
Company lost $312,027. During 1997, the Company lost $14,704 from operations and
during 1998 lost $180,941 from operations.

Three Months Ended March 31, 1998 and March 31, 1999

     Revenues. Revenues decreased by $253,282 in the first quarter of 1999
compared to the first quarter of 1998 due to the loss of hospital contracts.
This decrease in revenues also resulted in a decrease in operating expenses in
the effort to restore the Company

                                       20

<PAGE>

to profitability.

     Salaries, Payroll Taxes and Benefits. Salaries and payroll decreased by
$188,464 as a result of fewer personnel being employed at the Company by the end
of the first quarter of 1999 compared to 1998. The reduction in personnel was a
consequence of the loss of certain hospital contracts.

     Equipment Leasing and Laboratory Costs. Equipment leasing and laboratory
costs decreased by $199,875 in the first quarter of 1999 compared to the first
quarter of 1998 due to the loss of certain hospital contracts.

     Other Administrative Expenses. Other administrative expenses increased by
$149,464 in the first quarter of 1999 compared to the first quarter of 1998 due
to the extraordinary expenses related to the loss of certain hospital contracts.

     Rent and Occupancy Costs. Rent and occupancy costs increased by $6,153 in
the first quarter of 1999 compared to the first quarter of 1998 due to moving
the corporate headquarters while subletting the previous corporate headquarters
space at a price that was less than the entire amount of the lease payment due.

     Interest. Interest expenses increased by $2,278 in the first quarter of
1999 compared to the first quarter of 1998 due to an increase in the amount of
borrowing undertaken by CLI during the first quarter of 1999.

     Net Gain (Loss). The Company lost $6,359 during the first quarter of 1999
compared to a gain of $16,481 during the first quarter of 1998. This loss was
due to the winding down of certain operations due to the loss of certain
hospital contracts.

Three Months Ended June 30, 1998 and June 30, 1999

     Revenues. Revenues decreased by $218,288 in the second quarter of 1999 as
compared to the second quarter of 1998 due to the loss of hospital contracts.

     Salaries, Payroll Taxes and Benefits. Salaries and payroll decreased by
$75,872 as a result of fewer personnel being employed at the in the second
quarter of 1999 as compared to the second quarter of 1998. The reduction in
personnel was a continued consequence of the loss of certain hospital contracts.


                                       21

<PAGE>

     Equipment Leasing and Laboratory Costs. Equipment leasing and laboratory
costs decreased by $36,304 in the second quarter of 1999 as compared to the
second quarter of 1998 due to the loss of certain hospital contracts.

     Other Administrative Expenses. Other administrative expenses decreased by
$70,394, in the second quarter of 1999 as compared to the second quarter of 1998
due to the decrease in expenses associated with the loss of certain hospital
contracts.

     Interest. Interest expenses increased by $13,964 in the second quarter of
1999 as compared to the second quarter of 1998 due to an increase in the amount
of borrowing undertaken by CLI during the second quarter of 1999.

     Net Gain (Loss). The Company earned $11,385 in the second quarter of 1999
as compared to $57 during the second quarter of 1998.

     In April 1998, the American Institute of Certified Public Accountants
issued Statement of Position 98-5, "Reporting on the Costs of Start-Up
Activities." Statement of Position 98-5, which is effective for fiscal years
beginning after December 15, 1998, provides guidance on the financial reporting
of start-up costs and organization costs. It requires costs of start up
activities and organization costs to be expensed as incurred. As the Company has
expensed these costs historically, the adoption of this standard is not expected
to have a significant impact on the results of operations, financial position or
cash flows.

Liquidity and Capital Resources.

     During the 1998 calendar year, net cash of $274,410 was used by operating
activities, primarily due to the net loss of $312,027. The net cash provided by
financing activities of $244,182 was principally due to the proceeds from
promissory notes and issuance of long term debt. As of December 31, 1998, the
Company had negative working capital of $47,928.

     For the six month period ended June 30, 1999, cash of $78,631 was generated
by operating activities, primarily due to the decrease in accounts receivable.
On June 30, 1999, the Company had working capital of $218,074. The increase in
working capital is attributable in part to the extension of the maturity date of
outstanding short-term debt.


                                       22

<PAGE>

     On May 21, 1999, the Company received a Notice of Default from ATL
Financial Services, Inc., one of its equipment leasing companies. This default
was related to the loss of several hospital contracts to a competitive company
formed by the former Chief Executive Officer of CLI. Prior to the default being
declared, CLI claimed that the leasing company had interfered with certain of
the lost hospital contracts and actively assisted CLI's competitor to cause
these contracts to be breached. CLI further claimed that the leasing company had
extended the equipment leases in question based, in part, on the very hospital
contracts that had been interfered with. On July 29, 1999, the matter was
settled by the return of certain leased equipment to the leasing company and the
purchase of certain leased equipment by CLI from the leasing company.

     Concurrent with the settlement and release with the equipment leasing
company, CLI entered into a 38 month term loan agreement with DVI Financial
Services ("DVI") in the amount of $440,000 for the purchase of three ultrasound
systems and related peripheral equipment from ATL Financial Services pursuant to
the settlement agreement.

     On June 30, 1999, CLI entered into a Loan and Security Agreement with DVI
for a revolving line of credit up to a maximum of $1,000,000 collateralized by
the accounts receivable and related assets of CLI. Under the terms of the
agreement, 80% of the calculated collectable receivables under 120 days old are
eligible to be borrowed. The term of the agreement is two years, with annual
renewal thereafter. The interest rate is the prime rate plus 2.25% per annum,
plus additional expenses related to maintaining the line of credit. Initial
proceeds from this line of credit were used to pay off the outstanding
obligation under the terms of CLI's commercial line of credit with Prime Bank.
As of June 30, 1999, the total amount outstanding under the DVI line of credit
was $254,000. The line of credit is guaranteed by CLIX.

     In June 1999, the holders of $125,000 of promissory notes originally due in
March 1999, agreed to extend the maturity date thereof until July 1, 2002. As
part of the extension, the interest rate was increased from 7% to 11% per annum.
The holders of the notes have also subordinated the notes to the debt financing
provided by DVI.

     Management believes that the Company's cash and capital resources, together
with cash flow from operations, will be sufficient to finance current and
forecasted operations including

                                       23

<PAGE>

its capital spending and expansion plans. The Company is, however, actively
seeking additional equity financing. No assurance can be given that such
financing efforts will be successful.

Item 3. Description of Property.

     The Company's Wayne executive offices consist of approximately 1,900 square
feet. The lease agreement expires in April 2000. The lease provides for a base
rental of approximately $2,400 per month. During April 1998, the Company moved
from its prior executive offices located in Doylestown, Pennsylvania to its
current Wayne office. The prior location is currently subleased by the Company
for $2,200 per month which is less than the base monthly rental due of $2,500.
The Doylestown lease expires in April 2000.

     Each Director holds office until the next annual meeting of shareholders
and until his successor has been elected and qualified. The following is a
summary of the business experience of each executive officer and Director.

     Timothy W. Cunningham has been Chairman of CLIX since the acquisition of
CLI in April 1998. Prior to the acquisition event, he was Chairman of CLI. Mr.
Cunningham has served as President of Springhouse Associates, Inc., a consulting
firm, from 1989 to the present, and as President of Benson White & Company, an
asset management firm, from 1984 through April 1998. From 1984 through 1988, Mr.
Cunningham was Vice President of Keystone Venture Capital, a venture capital
organization headquartered in Philadelphia. From 1976 through 1983 he worked in
various management capacities with Bucyrus-Erie Co., a manufacturer of mining

par value $.001 ("Common Stock"). As of July 31, 1999, there were 7,799,793
shares of Common Stock issued and outstanding. As of such date, there were also

Common Stock

     The holder of each share of Common Stock is entitled to one vote on all
matters submitted to a vote of the shareholders of the Company, including the
election of directors. There is no cumulative voting for directors. The holders
of Common Stock are entitled to receive such dividends as the Board of Directors
may from time to time declare out of funds legally available for payment of
dividends. Upon any liquidation, dissolution or winding up of the Company,

                                       28

<PAGE>

for or purchase shares, obligations, or other securities of the Company.

PART II

Item 1. Market for Common Equity and Other Stockholder Matters.

     The Common Stock of the Company is quoted on the OTC Electronic Bulletin
Board under the symbol "CLIX." Prior to the acquisition of CLI, trading in the
Company's stock was nominal, as the Company had been inactive since 1992.
Commencing June 1, 1998, the Common Stock began trading more actively. As of the
date hereof, however, there is no established trading market for the Common
Stock.

     The following table sets forth, for the periods indicated, the range of
high and low bid prices of the Common Stock as reported on the OTC Electronic
Bulletin Board for each calendar quarter commencing June 1, 1998:

Quarter
Ended         9-30-98         12-31-98          3-31-99          6-30-99
- -----         -------         --------          -------          -------
High           $0.94            $0.63            $1.19            $0.44
Low            $0.18            $0.12            $0.22            $0.19

Such quotations reflect inter-dealer prices, without mark-up, mark down or
commissions and may not represent actual transactions.

     On September 2, 1999, the closing bid price of the Common Stock as reported
on the OTC Electronic Bulletin Board was $.16 per share.

     The Company's transfer agent is Standard Registrar And Transfer, 12528
South 1840 East, Draper, Utah 84020.

     As of July 31, 1999, CLIX had 429 holders of record of its Common Stock.

     CLIX has never paid any dividends on its Common Stock and does not
anticipate paying any cash dividends for the foreseeable future. The current
loan agreement with the Company's secured lender prohibits the payment of
dividends on the Common Stock without the prior written consent of such lender.

1998 Stock Option Plan

     CLIX has established a stock option plan entitled the 1998 CLI Stock Option
Plan (the "Plan"). Under the terms of the Plan, the Company's Board of
Directors, at its sole discretion, may grant either incentive stock options
within the meaning of Section 422 of the Internal Revenue Code or non-qualified
stock options. All persons employed by the Company or retained as independent
contractors are eligible for the award of stock options. The aggregate maximum
number of shares available under the Plan is 1,750,000. As of July 31, 1999,
there were a total of 260,000 options outstanding under the Plan at an exercise
price of $0.10 per share, with 170,000 of such options being fully vested as of
July 31, 1999. All of such options are non-qualified stock options and expire on
December 31, 2009.

     The Company has also issued to certain Directors, employees, and
consultants, options to purchase an aggregate of 1,400,000 shares of Common
Stock. Of such options, 725,000 expire in May 2002, 50,000 expire in June 2002,
500,000 expire in July 2002, and 125,000 expire in April 2003. Of such options,
700,000 are exercisable at $.01 per share, and 700,000 are exercisable at $2.00
per share. As of July 31, 1999, an aggregate of 1,100,000 of such options are
vested. All of the foregoing options are non-qualified stock options and not
part of a qualified stock option plan and do not constitute incentive stock
options as such term is defined under Section 422 of the Internal Revenue Code,
as amended, and are not part of an employee stock purchase plan as described in
Section 423 thereunder.

     As part of the issuance of 50,000 shares of Common Stock to a financial
advisor in December 1998, the Company granted to such financial advisor certain
registration rights under the Act in connection with such shares.

Item 2.  Legal Proceedings.

     In May 1998, the Company commenced an action entitled Cardiovascular
Laboratories, Inc. of New Jersey and Cardiovascular Laboratories, Inc. of
Pennsylvania vs. Robert T. Kane, Phoenix Cardiovascular, Inc., Warren Hospital,
and Albert Estrada, M.D.; Superior Court of New Jersey, Warren County (Docket
No. WRN-L-428-98).

     This litigation arises out of Warren Hospital's breach of the agreement
between CLI and Warren Hospital pursuant to which CLI

                                       30

<PAGE>

would provide vascular diagnostic services at Warren Hospital. The Complaint
also alleges that Phoenix Cardiovascular, Inc. ("Phoenix") and it founder and
principal, Robert T. Kane ("Kane"), tortiously interfered with and civilly
conspired to induce Warren Hospital to breach the agreement. Kane is the former
Chief Executive Officer and President of CLI. Between the filing of this action
and December 1998, Warren Hospital continued to honor the terms of the
agreement. In December 1998, Warren Hospital notified the Company that it would
no longer use the services of CLI and commenced using the services of Phoenix.
CLI initially filed a request for a preliminary injunction seeking to enjoin any
further interference with the Company's contract. The request was denied. CLI
seeks judgement against the defendants, jointly and severally, for compensatory
damages in excess of $500,000 as well as punitive damages, interest, attorneys'
fees and costs.

     The Company is a defendant in an action entitled Devendra K. Amin, M.D. vs.
Warren Hospital, Cardiovascular Laboratories, Inc. of Pennsylvania, and Robert
T. Kane; Superior Court of New Jersey, Warren County (Docket No. WRN-L-172-95).

     This litigation was filed in late May 1995 by a cardiologist at Warren
Hospital who sought but was not granted the privilege of interpreting vascular
studies at Warren Hospital's vascular laboratory, which was then managed by the
Company. Plaintiff brought claims against Warren Hospital, CLI, and its then
President, Robert T. Kane, and other persons. Plaintiff's claims against Warren
Hospital are for breach of contract, breach of implied duty of good faith and
fair dealing, and specific performance. Plaintiff's claims against the other
defendants, including CLI, are for intentional interference with prospective
economic advantage, conspiracy, and violation of state and federal antitrust
laws. Plaintiff seeks compensatory and punitive damages, attorney's fee, and
costs, as well as treble damages in the antitrust counts. Each of the defendants
has filed cross claims for contribution and indemnification against the other
unrelated defendants. From the outset of the litigation, CLI provided counsel to
Kane, its former Chief Executive Officer, but in 1998, CLI advised him that it
would no longer do so and would not indemnify him in connection with plaintiff's
claims in this action. Kane has asserted cross claims for contribution and
indemnification against CLI. The case is presently in discovery and it is
anticipated that trial will be scheduled during the Fall of 1999.

     The Company's Articles of Incorporation provide that the Board of Directors
may from time to time provide in the By-laws or by resolution such
indemnification of officers and directors as the Board deems appropriate to the
fullest extent permitted by the laws of the State of Nevada. Nevada law, under
which CLIX is incorporated, allows a corporation to indemnify its directors and
officers if such director or officer acted in good faith and in a manner such
director or officer reasonably believed to be in, or not opposed to, the best
interests of the Company and, with respect to any criminal action or proceeding,
had no reasonable cause to believe his conduct was unlawful.

     Pursuant to authorization of the Board of Directors in 1998, the Company
entered into separate indemnification agreements with each of Timothy W.
Cunningham, John R. Drexel, IV, and Paul A. Toomey. The agreements provide that
CLIX shall indemnify such persons and hold them harmless from and against, and
shall reimburse him for, any and all demands, claims, losses, damages, costs and
expenses whatsoever, including without limitation, reasonable attorney's fees,
which may be incurred by such person by reason of his faithful discharge of his
fiduciary obligations as an officer of or director of CLIX. The agreement also
provides that such person shall not be personally liable for monetary damages
for any action taken or any failure to act unless the breach or failure to
perform constitutes self-dealing, willful misconduct or recklessness and such
person had breached or failed to perform the

                                       34

<PAGE>

duties of his or her office. The agreement provides that the foregoing shall not
apply to the responsibility or liability of such person pursuant to any criminal
statute, or the liability of such person for the payment of taxes pursuant to
local, state or federal law.

                          INDEPENDENT AUDITORS' REPORT


Board of Directors
Cardiovascular Laboratories, Inc. and Subsidiaries
Wayne, Pennsylvania:

     We have audited the accompanying consolidated balance sheet of
Cardiovascular Laboratories, Inc. and subsidiaries (collectively, the "Company")
as of December 31, 1998, and the related consolidated statements of operations,
stockholders' equity and cash flows for the year then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit. The consolidated financial statements of Cardiovascular Laboratories,
Inc. and subsidiaries as of December 31, 1997, were audited by other auditors
whose report dated May 13, 1998, expressed an unqualified opinion on those
statements.

     We conducted our audit 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 1998 consolidated financial statements referred to
above present fairly, in all material respects, the financial position of
Cardiovascular Laboratories, Inc. and subsidiaries as of December 31, 1998, and
the results of their operations and their cash flows for the year then ended in
conformity with generally accepted accounting principles.

1. ORGANIZATION AND NATURE OF OPERATIONS

     Cardiovascular Laboratories, Inc. is a for-profit, Nevada holding company
     located in Wayne, Pennsylvania.

     The subsidiaries of Cardiovascular Laboratories, Inc. and their primary
     activities are as follows:

          Cardiovascular Laboratories, Inc. of Pennsylvania: Cardiovascular
          Laboratories, Inc. of Pennsylvania ("CLI-PA") is a wholly-owned,
          for-profit business corporation and subsidiary of Cardiovascular
          Laboratories, Inc. CLI-PA owns and operates independent vascular
          laboratories in hospitals and private clinics.

          CLIX: CLIX is a wholly-owned, for-profit business corporation and
          subsidiary of Cardiovascular Laboratories, Inc. CLIX was established
          to provide billing services; however, there was no substantial
          activity through December 31, 1998.

     Cardiovascular Laboratories, Inc. (formerly, Interstate Gold and Gas, Inc.)
     ("IG&G") was incorporated in the state of Utah on August 8, 1983. IG&G has
     been in the development stage since inception and has been engaged in the
     business of developing mining properties. During 1992, IG&G lost its
     remaining mining claims and since that date has been inactive.

     On March 9, 1998, a special shareholders meeting was held at which a
     resolution was approved to effectuate a reverse split of IG&G's common
     stock whereby all shareholders of record as of February 27, 1998 would
     receive one share of IG&G's common stock for each 500 shares owed. Also on
     this date, IG&G reincorporated as a Nevada corporation and changed its name
     to Cardiovascular Laboratories, Inc. ("CLI").

     Pursuant to an Acquisition Agreement dated March 26, 1998, CLI acquired all
     of the outstanding stock of CLI-PA by exchanging 2,546,837 unregistered
     shares of CLI for 1,000,000 shares of CLI-PA, exchanging 968,998
     unregistered shares of CLI for two option agreements to purchase
     substantially similar option agreements of CLI-PA, and issuing 1,500,000
     unregistered shares of CLI into an escrow trust. Additionally, CLI
     completed a public offering on April 30, 1998 under Regulation D of Rule
     504 of the Securities and Exchange Commission for a total of 2,250,000
     registered shares of CLI's common stock for total consideration of $22,500.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     PRINCIPLES OF CONSOLIDATION

          The consolidated financial statements include the accounts of
          Cardiovascular Laboratories, Inc. and its subsidiaries, CLI-PA and
          CLIX (collectively, the "Company"). All material intercompany
          transactions and balances have been eliminated in consolidation.

     USE OF ESTIMATES

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

     NET PATIENT SERVICE REVENUES AND RECEIVABLES

          Net patient service revenues and receivables are derived from
          hospitals and patients who reside primarily in the Company's regional
          geographical region (i.e., states of Pennsylvania, New Jersey and New
          York) and are reported at the estimated net realizable amounts from
          hospitals, patients, third party payors, and others for services
          rendered.

          Significant concentrations of revenues and accounts receivable, net
          include various hospitals and Medicare.

     FURNITURE, EQUIPMENT, AND VEHICLES

          Furniture, equipment and vehicles are recorded at cost. Depreciation,
          including amortization of capital lease obligations, is computed using
          the straight-line method based on the estimated useful life of each
          classification of depreciable asset.

     INCOME TAXES

          Deferred tax assets and liabilities are reflected at currently enacted
          income tax rates applicable to the period in which the deferred tax
          assets and liabilities are expected to be realized or settled. As
          changes to the tax laws or rates are enacted, deferred tax assets and
          liabilities are adjusted through the provision for income taxes.

     RECLASSIFICATIONS

          Certain reclassifications have been made to the 1997 financial
          statements to conform with the 1998 reporting format.


3. BASIS OF PRESENTATION AND CERTAIN
     SIGNIFICANT RISKS AND UNCERTAINTIES

     The Company's financial statements have been presented on the basis that it
     is a going concern, which contemplates the realization of assets and the
     satisfaction of liabilities in the normal course of business.

     The Company had a loss from operations of $180,941 in 1998 and $14,704 in
     1997 and a working capital deficiency of $47,928 at December 31, 1998.
     Additionally, the Company's operations were financed from proceeds of
     short-term promissory notes payable and long-term debt.

     These factors, among others, indicate that the Company's ability to
     continue in existence is dependent upon its ability to achieve profitable
     operations. The financial statements do not include any adjustments
     relating to the recoverability and classification of recorded assets and
     amounts that might be necessary should the Company be unable to continue in
     existence.

     Management's plans in connection with these matters are to continue to
     refine its operations, eliminate unprofitable contracts, expand sources of
     revenues, control operating expenses, refinance the note payable, demand
     and long-term lease agreements.


4. NET PATIENT SERVICE REVENUES AND RECEIVABLES

     The Company has agreements with hospitals and third party payors that
     provide for payments to the Company at amounts different from its
     established rates. A summary of major payment arrangements with hospitals
     and third party payors is as follows:

     HOSPITALS

          Patient services rendered to various hospitals are paid on a
          fee-for-service basis. These rates vary based on negotiated fee
          schedules.

     MEDICARE, BLUE SHIELD, AND MEDICAID

          Patient services rendered to Medicare, Blue Shield, and Medicaid
          program beneficiaries are paid based on various fee schedules. These
          rates vary according to patient classification systems that are based
          on clinical, diagnostic and other factors.

     OXFORD

          Patient services rendered to Oxford program beneficiaries are paid on
          a fee-for-service basis. These rates vary according to a patient
          classification system that is based on clinical, diagnostic, and other
          factors.

     The note is secured by substantially all assets of the Company. The
     outstanding balance under this agreement was $244,724 at December 31, 1998.

     The deferred income tax benefit in 1998 and 1997 results primarily from
     temporary differences in the recognition of accounts receivable, accounts
     payable and accrued expenses.

     The following represents the tax effects of temporary differences that
     result in the net deferred income tax liability at December 31, 1998 and
     1997:

     At December 31, 1998 and 1997, the Company has approximately $500,000 of
     net operating losses available to carry forward for federal and state
     income tax purposes. The federal net operating loss carryforwards will
     expire between 2004 and 2010 and the state net operating loss carryforwards
     will expire between 2000 and 2002.

     The expected income tax benefit using the statutory federal income tax rate
     differs from the actual income tax benefit primarily because of
     contributions and meals and entertainment.

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

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

     Lease expense for equipment and offices was $744,944 in 1998 and $666 in
     1997.

     CONTINGENCIES

          The health care industry is subject to numerous laws and regulations
          of federal, state and local governments. Compliance with these laws
          and regulations can be subject to future government review and
          interpretation as well as regulatory actions unknown or unasserted at
          the time. Recently, government activity has increased with respect to
          investigations and allegations concerning possible violations by
          health care providers of fraud and abuse statutes and regulations,
          which could result in the imposition of significant fines and
          penalties as well as significant repayments for net patient service
          revenues previously billed. Compliance with such laws and regulations
          are subject to future government review and interpretations as well as
          regulatory actions unknown or unasserted at this time.


12. COMMON STOCK TRANSACTIONS

     On May 8, 1998, the Company issued 134,000 shares of unregistered common
     stock to management consultants engaged by the Company and recognized
     $1,340 in consulting fees (based on the fair value of services performed).

13. STOCK OPTIONS AND AWARDS

     The Company has stock awards outstanding at December 31, 1998 granted under
     a stock option plan. The 1998 Stock Plan provides for the granting of stock
     awards to employees and qualified independent contractors in the form of
     options to purchase shares of common stock at a price equal to fair market
     value on the date of the grant. Options generally become exercisable at
     such time or times and subject to such terms and conditions as shall be
     determined by the Company at or after the grant.

     The total number of stock options granted to employees were for 260,000
     shares at an exercise price of $0.01 per share. The total number of stock
     options granted to independent contractors were for 1,075,000 shares at
     exercise prices ranging from $0.01 per share to $2.00 per share. No option
     or restricted stock award may be granted under the plan after December 31,
     2008.

     No compensation cost has been recognized for these stock options.


14. YEAR 2000 RISKS (UNAUDITED)

     Like virtually every organization, the Company is subject to risks
     associated with the Year 2000 Issue (the "Issue"). The Issue is the result
     of shortcomings in electronic data processing systems which affect computer
     software and hardware, transactions with customers, vendors and other
     organizations; and equipment dependent on microchips. The Company is in the
     process of assessing and implementing necessary changes related to the
     Issue but has not completed the process of identifying and remediating
     potential year 2000 problems. It is not possible for any organization to
     guarantee the results of its own remediation efforts or to accurately
     predict the impact of the Issue on third parties with which the Company
     does business.

     Because of the unprecedented nature of the Issue, its effects and the
     success of related remediation efforts will not be fully determinable until
     the year 2000 and thereafter. Management cannot assure that the Company is
     or will be year 2000 ready, that the Company's remediation efforts will be
     successful in whole or in part, or that entities with whom the Company does
     business will be year 2000 ready. If the Company's efforts or those of
     third parties with which it does business are not successful, the Issue
     could adversely affect the Company's operations and financial condition.

15. SUBSEQUENT EVENTS

     In January 1999, the Company was approached by a prospective acquirer with
     an unsolicited offer to acquire all its outstanding stock. The Company
     presented a Letter of Intent to the prospective acquirer that valued the
     transaction on the basis of approximately $1.25 per share of the Company's
     common stock. The Letter of Intent has a number of restrictions, the most
     important of which is the Company's ability to raise additional equity
     capital.

     The Company has hired an investment banker to represent it in the search
     for equity capital. The Company has also been in ongoing discussions with
     other groups concerning potential equity investment. None of these
     discussions has resulted in a firm commitment.

     In February 1999, the Company entered into a marketing services agreement
     with this same prospective acquirer. This agreement would provide the
     Company with access to proprietary interactive e-commerce software,
     databases and tools along with technical and marketing assistance. In
     return, the Company would pay a fee to this company based on its gross
     margin derived from such e-commerce business.

     In March 1999, the Company entered into a marketing agreement with another
     company. The Company would develop an e-commerce business with this company
     to sell preventative healthcare products, starting with nutritional
     supplements. In return, the Company would pay a royalty based on a
     percentage of revenues.

been lost, destroyed or wrongfully taken, a new certificate shall be issued in
place of the original certificate if the owner (a) so requests, before the
Corporation, has notice that the original certificate has been acquired by a
bona fide purchaser, and (b) files with the Corporation an indemnity bond in
such form and in such amount as shall be approved by the president or a vice
president of the Corporation, and (c) satisfies any other reasonable
requirements imposed by the Corporation. The Board of Directors may adopt such
other provisions and restrictions with reference to lost certificates, not
inconsistent with applicable law, as it shall in its discretion deem
appropriate.

any security interests, liens, or encumbrances of any kind. Without the Payee's
consent, the Maker Shall not sell, assign or otherwise dispose of any of the
Collateral. Upon reasonable written request of the Payee, and at the sole
expense of the Maker, the Maker will promptly deliver and duly execute and

attachment, perfection and priority of the second security interest granted
hereunder and of the rights and powers granted herein. A photocopy or other
reproduction of this Note or any financing statement shall be sufficient as a
financing statement for filing in any jurisdiction where so permitted. The Note,
and all other documents evidencing or securing the Loan executed by Maker in
favor of Payee are hereinafter referred to collectively as the "Loan Documents".

          (c) If any proceeding under the Bankruptcy Code or any law of the
     United States or of any state relating to insolvency or receivership is
     instituted by Maker or if any such proceeding is instituted against Maker
     and is consented to by the respondent or an order for relief shall be
     entered in such proceeding or such proceeding shall remain undismissed for
     sixty (60) days, or if Maker makes an assignment for the benefit of
     creditors, admits in writing its inability to pay debts generally as they

          (f) Upon the filing of dissolution proceedings or election to
     liquidate by or on behalf of Maker:

          (g) The entry of any final, unappealable judgment against Maker in
     excess of Ten Thousand Dollars ($10,000) which remains unsatisfied for
     fifteen (15) days or the issuance of any attachment, tax lien, levy or
     garnishment in excess of Ten Thousand Dollars ($10,000)) (except for
     carriers) against any property of material value in which Maker has an
     interest.

     7. DEFAULT RATE. Upon the occurrence of an Event of Default hereunder, the
interest rate otherwise payable under Section 2 hereof (the "Base Rate") shall
increase immediately and without notice and thereafter shall be payable at a
rate of four percent (4%) per annum in excess of the Base Rate (said higher rate
is hereinafter called the "Default Rate"), until the Event of Default has been
accelerated or is cured, until this Note is paid in full, including the period
following entry of any judgment on or relating to this Note or the other Loan
Documents. Interest on any such judgment shall accrue and be payable at the
Default Rate, and not at the statutory rate of interest, after judgment, any
execution thereon, and until actual receipt by the holder of payment in full of
this Note and said judgment. Interest at the Default Rate shall be collective as
part of any judgment hereunder and shall be secured by the Loan Documents.

     8. REMEDIES. Upon the occurrence of any Event of Default hereunder, the
entire unpaid principal balance of the Loan, together with all accrued and

Documents, shall, at the option of the holder hereof, become immediately due
and payable, without presentation, demand or further action of any kind and
Payee may forthwith exercise, singly, concurrently, successively or otherwise,
any and all rights and remedies available to Payee hereunder, or under any other
document executed in connection with the Loan or with respect to any collateral
pledged, mortgaged, or assigned a security therefor or otherwise available to
Payee at law or in equity. Maker agrees that any real estate that may be levied
upon pursuant to a judgment obtained by virtue hereof, on any writ of execution
issued thereon, may be sold upon any such writ in whole or in part in any order
described by Payee. The failure of the holder hereof to accelerate the
outstanding principal balance of the Loan upon the occurrence of an Event of
Default hereunder shall not constitute a waiver of such default or of the right
to accelerate the Loan at any time thereafter so long as the Event of Default
remains uncured.

     9. CONFESSION OF JUDGMENT. THE FOLLOWING PARAGRAPHS SET FORTH A WARRANT OF
ATTORNEY TO CONFESS JUDGMENT AGAINST MAKER. IN GRANTING THIS WARRANT OF
ATTORNEY, MAKER HEREBY KNOWINGLY, INTENTIONALLY AND VOLUNTARILY, AND ON THE
ADVICE OF ITS SEPARATE COUNSEL, UNCONDITIONALLY WAIVES ANY AND ALL RIGHTS WITH
RESPECT TO SUCH WARRANT THAT MAKER MAY HAVE PRIOR NOTICE TO PAYEE AND AN
OPPORTUNITY FOR HEARING UNDER THE CONSTITUTION AND LAWS OF THE UNITED STATES AND
THE COMMONWEALTH OF PENNSYLVANIA.

     UPON THE OCCURRENCE OF AN EVENT OF DEFAULT PURSUANT TO SECTION 6(a)) OR (c)
HEREUNDER, MAKE HEREBY IRREVOCABLY AUTHORIZED AND EMPOWERS ANY ATTORNEY OF
RECORD, OR THE PROTHONOTARY OR CLERK OF ANY COURT IN THE COMMONWEALTH OF
PENNSYLVANIA, OR ELSEWHERE, TO APPEAR FOR MAKER AT ANY TIME OR TIMES, IN ANY
SUCH COURT IN ANY ACTION BROUGHT AGAINST MAKER BY PAYEE WITH RESPECT TO THE
AGGREGATE AMOUNT PAYABLE HEREUNDER WITH OR WITHOUT DECLARATION FILED, AS OF ANY
TERM, AND THEREIN TO CONFESS OR ENTER JUDGMENT AGAINST MAKER FOR ALL SUMS
PAYABLE BY MAKER TO PAYEE HEREUNDER AS EVIDENCED BY AN AFFIDAVIT SIGNED BY A
DULY AUTHORIZED DESIGNEE OF PAYEE SETTING FORTH SUCH AMOUNT THEN DUE FROM MAKER
TO PAYEE, PLUS ATTORNEY'S FEES OF TEN PERCENT (10%) OF THE SUM OF THE FOREGOING,
BUT IN NO EVENT LESS THAN FIVE THOUSAND DOLLARS ($5,000.00), WITH COSTS OF
SUIT, RELEASE OF PROCEDURAL ERRORS AND WITHOUT RIGHT OF APPEAL. IF A COPY OF
THIS NOTE, VERIFIED BY AFFIDAVIT, SHALL HAVE BEEN FILED IN SUCH ACTION, IT SHALL
NOT BE NECESSARY TO FILE THE ORIGINAL AS A WARRANT OF ATTORNEY, MAKER WAIVES THE
RIGHT TO ANY STAY OR EXECUTION AND THE BENEFIT OF ALL EXEMPTION LAWS NOW

                                       3
<PAGE>

OR HEREAFTER IN EFFECT. NO SINGLE EXERCISE OF THE FOREGOING WARRANT AND POWER TO
BRING ANY ACTION OR CONFESS JUDGMENT THEREIN SHALL BE DEEMED TO EXHAUST THE
POWER, BUT THE POWER SHALL CONTINUE UNDIMINISHED AND MAY BE EXERCISED FROM TIME
TO TIME AS OFTEN AS PAYEE SHALL ELECT UNTIL ALL AMOUNTS PAYABLE TO PAYEE
HEREUNDER SHALL HAVE BEEN PAID IN FULL.

     10. WAIVERS BY MAKER, CUMULATIVE REMEDIES, ETC.

          (a) Maker hereby waives the benefit of any laws which now or hereafter
     might otherwise authorize the stay of any execution to be issued on any
     judgment recovered on this Note, or the exemption of any, property from
     levy, attachment and sale thereunder. Maker waives and releases unto the
     holder hereof and said attorney all errors, defects and imperfections
     whatsoever of a procedural nature in the entering of the said judgment or
     any process or proceedings relating hereto. Maker waives the right of
     inquisition on all real estate, voluntarily condemns it, and agrees that
     the real estate may be sold on writ of execution. MAKER HEREBY WAIVES ITS
     RIGHTS TO TRIAL BY JURY IN CONNECTION WITH THE ENFORCEMENT OF THIS NOTE OR
     ANY OTHER LOAN DOCUMENT IN ANY LEGAL PROCEEDINGS ARISING HEREUNDER OR
     THEREUNDER.

          (b) Maker and all endorsers of this obligation severally waive
     presentment, demand, protest and notice of nonpayment. Maker and the
     endorsers hereof and sureties therefor, if any, and all others who may be
     liable for all or any part of the indebtedness evidenced by this Note,
     consent to any number of renewals or extensions of the time of payment
     hereof without notice to any of those parties. The granting, without
     notice, of any extension of time for the payment of any sum due under this
     Note or for the performance of any covenant, condition or agreement hereof
     of thereof or the taking or release of other or additional security shall
     in no way release or discharge the liability of Maker or of any such
     endorsers or sureties.

          (c) No right or remedy conferred upon or serve to Payee hereunder or
     under any other document evidencing or securing the Loan, or with respect
     to any guaranty or any collateral securing the Loan, or now or hereafter
     existing at law or in equity or by statute or other legislative enactment,
     is intended to be exclusive of any other right or remedy, and each and
     every such right and remedy shall be cumulative and concurrent, and shall
     be in addition to every other such right and remedy, and may be pursued
     singly, concurrently, successively or otherwise, at the sole discretion of
     Payee, and shall not be exhausted by any one exercise thereof but may be
     exercised as often as occasion therefor shall occur. No act of Payee shall
     be deemed or construed as an election to proceed under any one such right
     or remedy the exclusion of any other such right or remedy; furthermore,
     each such right and remedy of Payee shall be separate, distinct and
     cumulative, and none shall be given effect to the exclusion of any other to
     exercise or delay in exercising any such right or remedy, or the failure to
     insist upon strict performance of any term of any of such documents, shall
     not be construed as a waiver or release of the same, or of any Event of
     Default, or any obligation or liability of Maker thereunder, nor shall
     Payee be deemed, by any act of omission or commission, to have waived any
     of its rights or remedies hereunder unless such waiver is in writing and
     signed by Payee and when only to the extent specifically set forth in the
     writing. A waiver as to one event shall not be construed as continuing or a
     bar to or waiver of any right or remedy as to a subsequent event.

          (d) The recovery of any judgment by Payee and/or the levy of execution
     under any judgment upon any collateral for the Loan shall not effect in any
     manner or to any extent the lien of any security interest in any such
     collateral, or any rights, remedies or powers of Payee under any documents
     evidencing or securing the Loan or with respect to any guaranty or any
     such collateral, but such lien and security interests and rights, remedies
     and powers of Payee shall continue unimpaired as before. The exercise by
     Payee of its rights and remedies and the entry of any judgment by payee
     shall not affect in any way the interest rate payable hereunder or any
     amounts due to Payee but interest shall continue to accrue on such amounts
     at the rate specified herein.

          (e) Maker agrees that any action or proceeding against it to enforce
     this Note may be commenced in the appropriate Court and Maker waives
     personal service process and agrees that a

                                       4
<PAGE>


     summons and complaint commencing an action or proceeding in any such court
     shall be properly served and shall confer personal jurisdiction if served
     by registered or certified mail in accordance with the notice provisions
     set forth herein.

          (f) The delivery of notice under this Note or under any other loan
     document shall constitute sufficient notice under all the Loan Documents,
     and the notice and cure periods provided in this Note and the other Loan
     Documents, if any be so provided, shall run concurrently and not
     consecutively. Time is of the essence of this Note.

     11. COSTS AND EXPENSES. If Payee retains the services of counsel in order
to enforce any remedy available to Payee under any document or instrument
evidencing or securing the Loan, attorney's fees as hereinbefore provided shall
be payable on demand by Maker to Payee, and Maker shall also pay on demand the
cost of any title search and all other costs incurred by Payee in connection
with proceedings to recover any sums due hereunder. Any such amounts not paid
promptly on demand shall be added to the outstanding principal balance of this
Note, shall bear interest at the Default Rate from the date of such demand until
paid in full and shall be secured by the Loan Documents. Maker shall also pay on
demand any reasonable recording and similar costs of Payee in connection with
the cancellation of this Note. Nothing contained in this Section ll shall
limit or impair the obligation of Maker to pay any and all costs and expenses
provided by law.

     12. NOTE TAXES, ETC. Maker shall pay the cost of any revenue and personal
property tax, tax, or other stamps now or hereafter required by the laws of the
Commonwealth of Pennsylvania, or the United States to be affixed to this Note.
If Maker does not or may not do so, Payee may at its option accelerate the
indebtedness evidenced by this Note to maturity as in the case of default by
Maker.

     13. INTEREST LIMITATIONS; SEVERABILITY.

          (a) Nothing herein contained nor any transaction related hereto shall
     be construed or shall operate either presently or prospectively to require
     Maker to pay interest at the rate greater than is now lawful in such case
     to contract for, but shall require payment of interest only to the extent
     of such lawful rate. Any interest paid in excess of the lawful rate shall
     be refunded to Maker. Such refund shall be made by application of the
     excessive amount of interest paid against any sums outstanding hereunder,
     and shall be applied in such order as Payee may determine. If the excessive
     amount of interest paid exceeds the sums outstanding hereunder, the portion
     exceeding the said sums outstanding hereunder shall be refunded in cash by
     Payee. Any such crediting or refund shall not cure or waive any default by
     Maker hereunder or under the other Loan Documents. Maker agrees, however,
     that in determining whether or not any interest payable hereunder exceeds
     the highest rate permitted by law, any non-principal payment (except
     payments specifically stated herein to be "interest"), shall be deemed, to
     the extent permitted by law, to be an expense, fee, premium, or penalty
     rather than interest.

          (b) In the event that for any reason one more of the provisions of
     this Note or their application to any person or circumstances shall be held
     to be invalid, illegal or unenforceable in any respect or to any extent,
     such provisions shall, to such extent, be held for naught as though not
     herein contained but shall nevertheless remain valid, legal and enforceable
     in all such other respects and to such extent as may be permissible. In
     addition, any such invalidity, illegality or unenforceability shall not
     affect any other provisions of this Note, but this Note shall be construed
     as if such invalid, illegal or unenforceable provisions had never been
     contained herein.

     14. NO JOINT VENTURE. Payee shall in no event be construed for any purpose
to be a partner, joint venture or associate of Maker or of any lessee, operator,
concessionaire, or licensee of Maker in the conduct of their respective
businesses.

     15. SUCCESSORS AND ASSIGNS. This Note inures to the benefit of Payee, his
heirs, personal representatives and assigns, and its binding upon Maker, its
successors, and assigns and the words "Payee" and "Maker" whenever used herein
shall be deemed and construed to include such respective personal
representatives successors, and assigns.

     16. NOTICES. All notices required to be given to any of the parties
hereunder shall be in writing and shall be deemed to have been sufficiently
given for all purposes when presented personally to such party or sent by
certified or registered mail, return receipt requested, or by courier service
with guaranteed overnight delivery, addressed to such party at its address as
set forth in the beginning of this Note. Such notice shall be deemed to be given
when received if delivered personally, or two (2) days after the date deposited
with the United States Postal Service if sent by certified or registered mail,
return receipt requested, or one (1) day after the same is delivered to a
courier service with guaranteed overnight delivery. Any notice of any change in
such address shall also be given in the manner set forth above. Whenever the
giving of notice is required, the giving of such notice may be waived in writing
by the party entitled to receive such notice.

     17. DEFINITIONS; NUMBER AND GENDER. In the event Maker consists of more
than one person or entity, the obligations and liabilities hereunder of each of
such persons and entities shall be joint and several and the word "Maker" shall
mean all or some of any of them. For purposes of this Note, the singular shall
be deemed to include the plural and the neuter shall be deemed to include the
masculine and feminine, as the context may require.

     18. CAPTIONS. The captions or headings of the sections of this Note are for
convenience only and shall not control or affect the meaning or construction of
any of the terms or provisions of this Note.

     19. GOVERNING LAW; AMENDMENT. This Note shall be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania. This Note may
only be amended by an instrument in writing signed by both Maker and Payee.

     20. ADDITIONAL CONSIDERATION; ISSUANCE OF SHARES OF MAKER. In addition to
the payment of all sums due under this Note to Payee, as additional
consideration to Payee for making the Loan to Maker, Maker agrees to issue to
Payee at the closing of this Loan that number of non-restricted and
freely-traded shares of common stock of Maker equal in value to the amount of
the principal due hereunder.

     21. SERIES OF NOTES. This Note is one of series of substantially identical
Notes issued by the Maker on even date herewith. Each individual Note entitles
the Note's Payee to all rights of payment of interest, principal and late
charges in accordance with the amounts set forth in each individual Note. Each
Note shall rank on a pari pasu and pro-rata basis with all other Notes with
respect to the Security Agreement set forth in Section 5. The declaration of an
Event of Default in any single Note shall be considered as an Event of Default
in all other Notes and the rights and remedies set forth in each Note shall be
applied on a pro-rata basis with respect to the relation between the principal
amount of each Note and the amount represented by the total of all of the
principal amounts of all Notes.

     22. USE OF PROCEEDS. The use of the proceeds from the issuance of all Notes
shall first be to repay Maker's revolving credit line outstanding with First
Service Bank of Doylestown, Pennsylvania account number 02-50060 in the
approximate amount of $122,603. Any proceeds in excess of this amount not
applied to fully repay the First Service Bank line shall be used for working
capital purposes by Maker. After the First Service Bank has been fully repaid,
Maker shall close the revolving credit line account.

     IN WITNESS WHEREOF, Maker, intending to be legally bound hereby, has caused
this Note to be duly executed, under seal, the date and year first above
written.

                       Anchor Investment Partnership Ltd.

This Amendment #1 (hereinafter referred to as the "Amendment") to the
Promissory Note dated March 30, 1998 (hereinafter the "Note") between
Cardiovascular Laboratories, Inc. (hereinafter referred to as the "Maker") and
Anchor Investment Partnership Ltd. (hereinafter referred to as, the "Payee") is
dated June 28, 1999.

WHEREAS Maker is unable, as of the date of this Amendment, to make payment
on the interest and principal as set forth in the Note; and Maker is thereby in
default of the terms and conditions set forth in the Note; and

WHEREAS Maker is entering into this Amendment to offer Payee incentive to
refrain from enforcing such remedies as the Payee is lawfully entitled to under
the terms of the Note; and

WHEREAS Payee wishes to retain its rights and remedies under the Note; and

WHEREAS Payee wishes to restructure Note to enhance the chance of obtaining
repayment of interest and principal of Note and to obtain such additional
payment as may be available under the terms of this Amendment.

NOW, THEREFORE, in consideration of their mutual covenants, and for other good
and valuable consideration, the receipt of which is hereby acknowledged, the
Parties hereto, intending to be legally bound, hereby agree to amend the Note as
follows:

1. Interest rate. In accordance with the terms of the Note, the interest rate on
the outstanding unpaid principal amount shall be increased to the Default Rate
(as defined in the original Note) of 11% per annum, which interest shall accrue
from April 1, 1999 until the Maker has paid the outstanding principal in its
entirety.

2. Principal and Interest Payment. Obligations under the Note shall remain
outstanding until repaid in their entirety. The final maturity of the Note shall
be extended to July 1, 2002, with twenty equal principal and interest payments
due on a monthly basis as set forth in Exhibit B. Additionally, any or all
outstanding principal and accrued but unpaid interest shall be eligible for
payment from the Payee's participation in the compensation plan of a proposed
network marketing organization organized to sell nutritional supplements
(hereinafter referred to as the ("NMO") as further described in this Amendment.

3. Current Interest Payments. Notwithstanding the provisions contained above in
Section 2 of this Amendment, Maker shall, in accordance with the provisions in
this Section 3, pay current interest at an 11% annualized rate on all
outstanding unpaid principal obligations


<PAGE>

under the Note and this Amendment. Such current interest payments shall begin
prior to the payment schedule set forth in Exhibit B to this Amendment under the
following conditions:

     A. Net Free Cash Flow Statements. Maker shall prepare a statement of net
     free cash flow on a quarterly basis showing the net free cash flows of
     Maker for each month in the preceding quarter and present such statements
     of net free cash flow to Payee no later than 30 days following the close of
     each calendar quarter. For the purposes of this Amendment, net free cash
     flow ("Net Free Cash Flow") shall mean the gross cash revenues received by
     the Maker during each month minus the gross cash payments made for expenses
     during each month.

     B. Current Interest Payments. Once Maker's Net Free Cash Flow reaches
     $2,500 or more for any calendar quarter, Maker shall become obligated to
     make interest payments to Payee on all outstanding principal amounts of the
     Note as follows: First; all accrued interest payments up to the amount of
     the Net Free Cash Flow. Second, all current interest payments to the end of
     the last quarter.

4. Network Marketing Organization. Maker and its affiliates intend to
launch a NMO that will consist of the creation of a multi-level marketing
distributor sales force to sell nutritional supplements. Maker represents and
Payee expressly acknowledges that the NMO is not yet established, and may never
become successful enough to repay the principal, and interest on the Note.
Notwithstanding this fact, however, in an effort to induce the Payee not to
exercise all of its rights and remedies under the terms of the Note, Maker
offers the following additional incentive to Payee:

     A. Establishment of NMO. The establishment of NMO shall take place as soon
     as Maker is able to do so following the execution of this Amendment. Maker
     represents and Payee expressly acknowledges that the establishment and
     successful operation of the NMO is subject to inherent uncertainties,
     including, but not limited to, the inexperience of Maker in the
     establishment and operation of NMO's such as that contemplated by Maker.

     B. Establishment of the Compensation Plan. Maker represents and warrants to
     Payee that Maker shall ensure that NMO shall have a compensation plan (the
     "Compensation Plan") established to compensate distributors on retail sales
     of products made by distributors in the NMO. Such Compensation Plan shall
     form a means by which Payee may have all obligations of Maker fulfilled as
     well as affording Payee the opportunity to earn additional payments above
     the full amount of interest and principal due under the Notes as amended
     under terms set forth in this Amendment to compensate Payee for their
     forbearance in accepting the terms of this Amendment.

     C. NMO Compensation Plan With Respect to Payee. The Compensation Plan is
     intended to motivate and incentivize independent distributors to build
     their business through revenues generated within their downline multi-level
     organization of distributors. The Compensation Plan shall be structured to
     permit the Payee to be compensated at 25% of the Presidential Level of the
     Compensation Plan. The Presidential Level of the Compensation Plan shall
     consist of a 10% override on all net sales made by all distributors in the
     NMO. For the Purposes of this Amendment, net sales ("Net Sales")

Page 2 of 4


<PAGE>

     shall refer to all revenues generated by the NMO for the sale of retail
     products within the NMO minus any credits for returned merchandise, credit
     card processing fees, distributor commissions, distributor rebates and
     royalties. It is expressly represented by Maker and acknowledged by Payee
     that this Compensation Plan may require the recruitment of experienced NMO
     management and/or capital to launch and grow the NMO, and that such
     management or investors may insist on being considered as distributors for
     the purposes of calculating Net Sales under this agreement. It is expressly
     represented by Maker and acknowledged by Payee that the formation,
     operation and success of the NMO is highly dependent on Timothy W.
     Cunningham ("Cunningham") and that therefore the Compensation Plan shall
     consider Cunningham as a distributor for the purposes of calculating Net
     Sales, provided, however, that any compensation received by Cunningham from
     NMO retail sales shall not exceed 5% of the Net Sales unless the Payee has
     received in excess of $500,000 in cumulative payment from the Compensation
     Plan, at which time Cunningham's compensation from the NMO shall be subject
     to adjustment by the Board of Directors of Maker at whatever level such
     Board believes appropriate given the contribution of Cunningham to the
     success of the NMO enterprise.

5. Payee Agrees to Subordiante Notes to DVIBC, No Action. Payee agrees to
subordinate the Note to DVIBC in accordance with Exhibit A, and to execute
Exhibit A as evidence of such subordination. Additionally, the Payee agrees to
take no further action evidencing a default under the original terms of the Note
provided Maker complies with the terms of this Amendment in its entirety.

6. Descriptive Headings, Arbitration/Jurisdiction of the Court. The headings of
the several paragraphs of this Amendment are inserted for convenience only
and do not constitute a part of this Amendment. Any controversy or claim arising
out of or relating to this Amendment, or the breach thereof, shall be
settled by arbitration in the County of Montgomery, Pennsylvania, USA,
in accordance with the rules of the American Arbitration Association there in
effect, except that the Parties thereto shall have any rights to discovery as
would be permitted by the Federal Rules of Civil procedure and the prevailing
Party shall be entitled to reasonable costs and reasonable attorney's fees from
arbitration or any other civil action. Judgement upon the award rendered therein
may be entered in any Court having jurisdiction thereof. Jurisdiction for any
legal action is stipulated between the Parties to lie in the County of
Montgomery, Pennsylvania, USA.

7. Partial Invalidity. In the event that one or more of the provisions contained
in this Amendment shall be held to be invalid, illegal or unenforceable in any
respect under any law, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.

8. Assignability. Except as otherwise provided herein, neither Party may assign
this Amendment or any right or obligation under this Amendment without the prior
written consent of the other Party, and any purported assignment without such
prior written consent shall be void and ineffective.

9. Notice. Any notice required or permitted herein shall be in writing and shall
be deemed to have been properly given if delivered personally, or if sent by
facsimile (with a copy mailed by international air mail or U.S. mail), or if
sent by international registered air mail, return

written or oral, and all such prior agreements or arrangements are hereby deemed

                             SUBORDINATION AGREEMENT

This Subordination Agreement ("Agreement") is made and entered into June 28,
1999 between James W. Porter, Jr. (hereinafter collectively and individually
referred to as the "Subordinated Creditor"), Cardiovascular Laboratories. Inc.
of PA ("Debtor"), and DVI Business Credit Corporation ("DVIBC").

                                    RECITALS

WHEREAS, Debtor is indebted to Subordinated Creditor; and

WHEREAS, Debtor desires to obtain leases, loans, extensions of credit, and other
financial services from DVIBC; and

WHEREAS, DVIBC is unwilling to extend credit or provide financial services to
Debtor unless Debtor and Subordinated Creditor enters into this Agreement with
DVIBC.

NOW, THEREFORE, for value received and in consideration of the mutual covenants
herein, and to induce DVIBC to extend credit and provide financial services to
Debtor, the parties hereto intend to be legally bound, hereby, do agree as
follows:

                                    AGREEMENT

     1. For the purposes of this Agreement the following definitions shall
apply:

     1.1 "Junior Debt" means all loans, advances, liabilities, debit balances,
covenants and duties at any time owed by Debtor to Subordinated Creditor,
whether direct or indirect, absolute or contingent, secured or unsecured, due or
to become due, now existing or hereafter arising, and whether created directly
or acquired indirectly by assignment, pledge, purchase or otherwise and whether
arising in connection with creditors, shareholders, directors or officers'
rights or other rights to distributions, dividends, salaries, bonuses, loan
payments, note payments, professional fees, management fees, or compensation of
any nature whether matured or not, together with all interest, fees, charges,
expenses and attorneys' fees for which Debtor is now or hereafter becomes liable
to pay to Subordinated Creditor under any agreement or by law.

     1.2 "Senior Debt" means all loans, advances, liabilities, debit balances,
covenants and duties at any time owed by Debtor to DVIBC, whether direct or
indirect, absolute or contingent, secured or unsecured, due or to become due,
now existing or hereafter arising, including without limitation any debt,
liability or obligation owing from Debtor to others which DVIBC may have
obtained by assignment, pledge, purchase or otherwise, together with all
interest, fees, charges, expenses and attorneys' fees for which Debtor is now or
hereafter becomes liable to pay to DVIBC under any agreement or by law, and
including all deferrals, renewals, extensions, refundings and refinancings, in
whole or in part of any of the foregoing.

     2. Subordinated Creditor hereby postpones and subordinates, to the extent
and in the manner provided in this Agreement, all of the Junior Debt, to the
payment of all of the Senior Debt. If Debtor issues or has issued any instrument
or document evidencing the Junior Debt, each such instrument and document
shall bear a conspicuous legend that it is subordinated to the Senior Debt. All
instruments and documents evidencing the Junior Debt shall upon request be
delivered DVIBC properly assigned or endorsed to DVIBC.

     3. Subordinated Creditor agrees not to sue upon, or to collect, or to
receive payment upon, by setoff in any other manner, the Junior Debt, now or
hereafter existing, nor to sell, assign, transfer, pledge, or give a security
interest in the Junior Debt (except subject expressly to this Agreement), nor to
enforce or apply any security now or hereinafter existing, nor to join in any
petition to bankruptcy or any assignment for the benefit of creditors, or any
creditors agreement, not to take any lien or security on Debtor's property real
or personal, nor to incur any obligations nor to receive distributions except as
provided in Section 4 below, any lows, advances or gifts from Debtor, so long as
any Senior Debt shall exist or so long as DVIBC is committed or otherwise
obligated to make any loan to or grant any credit to Debtor.

     4. All Senior Debt now or hereafter existing shall be first paid by Debtor
before any payment shall be made by Debtor to Subordinated Creditor on the
Junior Debt; provided, however that so long as (a) no Event of Default, or any
event which with the giving of notice or lapse of time (or both) would
constitute an Event of Default (as defined in any agreement evidencing any
Senior Debt) exists with respect to any Senior Debt; or (b) such payment will
not cause such an Event of Default, or otherwise render Debtor unable to pay the
Senior Debt, Debtor may pay valid claims owing to Subordinated Creditor incurred
in the ordinary course of business in accordance with the terms of that certain
Promissory Note of Debtor payable to Subordinated Creditor in the original
principal amount of $50,000, dated as of March 30, 1998 (which shall not be
modified without DVIBC's written consent thereto), but not by prepayment,
acceleration or otherwise.

     5. The priority of payment set forth in Section 4 above shall apply during
the ordinary course of Debtor's business and in case of any assignment by Debtor
for the benefit of Debtor's creditors, and in case of any bankruptcy proceedings
instituted by or against Debtor's assets, and in case of any dissolution or
other winding up of the affairs of Debtor, or of Debtor's business, and in all
such cases respectively, the officers of Debtor and any assignee, trustee in
bankruptcy, receiver, and other person or persons in charge are hereby

                                        1

directed to pay DVIBC the full amount of any Senior Debt before making any
payments to Subordinated Creditor, and so far as may be necessary for that
purpose, Subordinated Creditor hereby transfers, assigns and grants to DVIBC a
security interest in all of its interests and rights in and to the Junior Debt.

     6. DVIBC is hereby irrevocably constituted and appointed the
attorney-in-fact of Subordinated Creditor with full power to act in the place
and stead of Subordinated Creditor, to make, present, file and vote any and all
proofs of claim and any other documents and to take all other action, either in
DVIBC's name or in the name of the Subordinated Creditor, which in DVIBC's
opinion is necessary or desirable to enable DVIBC to effectuate the provisions
of this Agreement.

     7. No subordination of any Junior Debt has previously been executed by
Subordinated Creditor for the benefit of anyone else and any such subordinations
hereafter executed will be and shall be expressed to be subject and subordinate
to the effect hereof. This Agreement shall be continuing in effect, it shall not
be cancelled or otherwise rendered ineffective by the payment or discharge at
any time of the Senior Debt, and it shall apply to any and all Senior Debt
subsequently granted, renewed or extended by DVIBC for Debtor, unless
Subordinated Creditor shall deliver to DVIBC a written notice of revocation as
to future transactions at a time when Debtor is no longer obligated to DVIBC in
any way and while DVIBC is not committed to or otherwise obligated to make any
leases, loans or other financial accommodations to Debtor.

     8. Subordinated Creditor hereby further agrees that Subordinated Creditor
shall not permit Debtor to: (i) make payment to any of the other parties
constituting a relative, affiliate or related in any way to Subordinated
Creditor contrary to the terms of this Agreement, including, without limitation,
payment of any distribution, professional fees, salary, bonus or other form of
compensation to Subordinated Creditor; and (ii) make payment to any other party
other than DVIBC in satisfaction of any Senior Debt and any other obligations as
may be owing to DVIBC from time to time except as may otherwise be consented to
by DVIBC in writing.

     9. THE CONSTRUCTION, INTERPRETATION, VALIDITY AND ENFORCEABILITY OF THIS
AGREEMENT SHALL BE GOVERNED IN ALL RESPECTS BY THE LAWS OF THE STATE OF
CALIFORNIA. SUBORDINATED CREDITOR AGREE TO SUBMIT TO THE JURISDICTION AND VENUE
OF THE STATE AND THE FEDERAL COURTS IN CALIFORNIA. In any action, suit,
arbitration, or mediation relating to the enforcement of this Agreement the
prevailing party shall be entitled to recover its costs and expenses including
reasonable attorneys' fees.

     10. This Agreement may be signed in any number of counterparts, each of
which will constitute an original, and all of which, taken together, shall
constitute but one and the same agreement.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly
executed as of the date first written.

the purposes of obtaining or preserving the full benefits of, and the
attachment, perfection and priority of the second security interest granted
hereunder and of the rights and powers granted herein. A photocopy or other
reproduction of this Note or any financing statement shall be sufficient as a
financing statement for filing in any jurisdiction where so permitted. The Note,
and all other documents evidencing or securing the Loan executed by Maker in

     hereunder when such payment is due and such failure continues for ten (10)
     business days after written notice to Maker:

          (b) If there occurs any default under or specified in any other Loan
     Document and such default continues after the expiration of the applicable
     notice and grace periods, if any, provided therein;

          (c) If any proceeding under the Bankruptcy Code or any law of the
     United States or of any state relating to insolvency or receivership is
     instituted by Maker or if any such proceeding is instituted against Maker
     and is consented to by the respondent or an order for relief shall be
     entered in such proceeding or such proceeding shall remain undismissed for
     sixty (60) days, or if Maker makes an assignment for the benefit of
     creditors, admits in writing its inability to pay debts generally as they
     become due or becomes insolvent:

          (d) If any representation, warranty, certificate, financial statement
     or other information made or given by Maker to Payee is materially

          (e) If Maker sells or transfers any of the stock (issued or unissued)
     or assets of Maker, in individual transactions or in the aggregate (other
     than in the ordinary course of business, as to assets) and including if by

                                       2

          (f) Upon the filing of dissolution proceedings or election to
     liquidate by or on behalf of Maker:

          (g) The entry of any final, unappealable judgment against Maker in
     excess of Ten Thousand Dollars ($10,000) which remains unsatisfied for
     fifteen (15) days or the issuance of any attachment, tax lien, levy or
     garnishment in excess of Ten Thousand Dollars ($10,000)) (except for
     carriers) against any property of material value in which Maker has an
     interest.

     7. DEFAULT RATE. Upon the occurrence of an Event of Default hereunder, the
interest rate otherwise payable under Section 2 hereof (the "Base Rate") shall
increase immediately and without notice and thereafter shall be payable at a
rate of four percent (4%) per annum in excess of the Base Rate (said higher rate
is hereinafter called the "Default Rate"), until the Event of Default has been
accelerated or is cured, until this Note is paid in full, including the period
following entry of any judgment on or relating to this Note or the other Loan
Documents. Interest on any such judgment shall accrue and be payable at the
Default Rate, and not at the statutory rate of interest, after judgment, any
execution thereon, and until actual receipt by the holder of payment in full of
this Note and said judgment. Interest at the Default Rate shall be collective as
part of any judgment hereunder and shall be secured by the Loan Documents.

     8. REMEDIES. Upon the occurrence of any Event of Default hereunder, the
entire unpaid principal balance of the Loan, together with all accrued and
unpaid interest thereon and all other sums owing hereunder or under the Loan
Documents, shall, at the option of the holder hereof, become immediately due
and payable, without presentation, demand or further action of any kind and
Payee may forthwith exercise, singly, concurrently, successively or otherwise,
any and all rights and remedies available to Payee hereunder, or under any other
document executed in connection with the Loan or with respect to any collateral
pledged, mortgaged, or assigned a security therefor or otherwise available to
Payee at law or in equity. Maker agrees that any real estate that may be levied
upon pursuant to a judgment obtained by virtue hereof, on any writ of execution
issued thereon, may be sold upon any such writ in whole or in part in any order
described by Payee. The failure of the holder hereof to accelerate the
outstanding principal balance of the Loan upon the occurrence of an Event of
Default hereunder shall not constitute a waiver of such default or of the right
to accelerate the Loan at any time thereafter so long as the Event of Default
remains uncured.

     9. CONFESSION OF JUDGMENT. THE FOLLOWING PARAGRAPHS SET FORTH A WARRANT OF
ATTORNEY TO CONFESS JUDGMENT AGAINST MAKER. IN GRANTING THIS WARRANT OF
ATTORNEY, MAKER HEREBY KNOWINGLY, INTENTIONALLY AND VOLUNTARILY, AND ON THE
ADVICE OF ITS SEPARATE COUNSEL, UNCONDITIONALLY WAIVES ANY AND ALL RIGHTS WITH
RESPECT TO SUCH WARRANT THAT MAKER MAY HAVE PRIOR NOTICE TO PAYEE AND AN
OPPORTUNITY FOR HEARING UNDER THE CONSTITUTION AND LAWS OF THE UNITED STATES AND
THE COMMONWEALTH OF PENNSYLVANIA.

HEREUNDER, MAKE HEREBY IRREVOCABLY AUTHORIZED AND EMPOWERS ANY ATTORNEY OF
RECORD, OR THE PROTHONOTARY OR CLERK OF ANY COURT IN THE COMMONWEALTH OF
PENNSYLVANIA, OR ELSEWHERE, TO APPEAR FOR MAKER AT ANY TIME OR TIMES, IN ANY
SUCH COURT IN ANY ACTION BROUGHT AGAINST MAKER BY PAYEE WITH RESPECT TO THE
AGGREGATE AMOUNT PAYABLE HEREUNDER WITH OR WITHOUT DECLARATION FILED, AS OF ANY
TERM, AND THEREIN TO CONFESS OR ENTER JUDGMENT AGAINST MAKER FOR ALL SUMS

BUT IN NO EVENT LESS THAN FIVE THOUSAND DOLLARS ($5,000.00), WITH COSTS OF
SUIT, RELEASE OF PROCEDURAL ERRORS AND WITHOUT RIGHT OF APPEAL. IF A COPY OF
THIS NOTE, VERIFIED BY AFFIDAVIT, SHALL HAVE BEEN FILED IN SUCH ACTION, IT SHALL

OR HEREAFTER IN EFFECT. NO SINGLE EXERCISE OF THE FOREGOING WARRANT AND POWER TO
BRING ANY ACTION OR CONFESS JUDGMENT THEREIN SHALL BE DEEMED TO EXHAUST THE
POWER, BUT THE POWER SHALL CONTINUE UNDIMINISHED AND MAY BE EXERCISED FROM TIME
TO TIME AS OFTEN AS PAYEE SHALL ELECT UNTIL ALL AMOUNTS PAYABLE TO PAYEE
HEREUNDER SHALL HAVE BEEN PAID IN FULL.

     10. WAIVERS BY MAKER, CUMULATIVE REMEDIES, ETC.

          (a) Maker hereby waives the benefit of any laws which now or hereafter
     might otherwise authorize the stay of any execution to be issued on any
     judgment recovered on this Note, or the exemption of any, property from
     levy, attachment and sale thereunder. Maker waives and releases unto the
     holder hereof and said attorney all errors, defects and imperfections
     whatsoever of a procedural nature in the entering of the said judgment or
     any process or proceedings relating hereto. Maker waives the right of
     inquisition on all real estate, voluntarily condemns it, and agrees that
     the real estate may be sold on writ of execution. MAKER HEREBY WAIVES ITS
     RIGHTS TO TRIAL BY JURY IN CONNECTION WITH THE ENFORCEMENT OF THIS NOTE OR
     ANY OTHER LOAN DOCUMENT IN ANY LEGAL PROCEEDINGS ARISING HEREUNDER OR
     THEREUNDER.

          (b) Maker and all endorsers of this obligation severally waive
     presentment, demand, protest and notice of nonpayment. Maker and the
     endorsers hereof and sureties therefor, if any, and all others who may be
     liable for all or any part of the indebtedness evidenced by this Note,
     consent to any number of renewals or extensions of the time of payment
     hereof without notice to any of those parties. The granting, without
     notice, of any extension of time for the payment of any sum due under this
     Note or for the performance of any covenant, condition or agreement hereof
     of thereof or the taking or release of other or additional security shall
     in no way release or discharge the liability of Maker or of any such
     endorsers or sureties.

          (c) No right or remedy conferred upon or serve to Payee hereunder or
     under any other document evidencing or securing the Loan, or with respect
     to any guaranty or any collateral securing the Loan, or now or hereafter
     existing at law or in equity or by statute or other legislative enactment,
     is intended to be exclusive of any other right or remedy, and each and
     every such right and remedy shall be cumulative and concurrent, and shall
     be in addition to every other such right and remedy, and may be pursued
     singly, concurrently, successively or otherwise, at the sole discretion of
     Payee, and shall not be exhausted by any one exercise thereof but may be
     exercised as often as occasion therefor shall occur. No act of Payee shall
     be deemed or construed as an election to proceed under any one such right
     or remedy the exclusion of any other such right or remedy; furthermore,
     each such right and remedy of Payee shall be separate, distinct and
     cumulative, and none shall be given effect to the exclusion of any other to
     exercise or delay in exercising any such right or remedy, or the failure to
     insist upon strict performance of any term of any of such documents, shall
     not be construed as a waiver or release of the same, or of any Event of
     Default, or any obligation or liability of Maker thereunder, nor shall
     Payee be deemed, by any act of omission or commission, to have waived any
     of its rights or remedies hereunder unless such waiver is in writing and
     signed by Payee and when only to the extent specifically set forth in the
     writing. A waiver as to one event shall not be construed as continuing or a
     bar to or waiver of any right or remedy as to a subsequent event.

          (d) The recovery of any judgment by Payee and/or the levy of execution
     under any judgment upon any collateral for the Loan shall not effect in any
     manner or to any extent the lien of any security interest in any such
     collateral, or any rights, remedies or powers of Payee under any documents
     evidencing or securing the Loan or with respect to any guaranty or any
     such collateral, but such lien and security interests and rights, remedies
     and powers of Payee shall continue unimpaired as before. The exercise by
     Payee of its rights and remedies and the entry of any judgment by payee
     shall not affect in any way the interest rate payable hereunder or any
     amounts due to Payee but interest shall continue to accrue on such amounts
     at the rate specified herein.

          (e) Maker agrees that any action or proceeding against it to enforce
     this Note may be commenced in the appropriate Court and Maker waives
     personal service process and agrees that a

                                       4
<PAGE>


     summons and complaint commencing an action or proceeding in any such court
     shall be properly served and shall confer personal jurisdiction if served
     by registered or certified mail in accordance with the notice provisions
     set forth herein.

          (f) The delivery of notice under this Note or under any other loan
     document shall constitute sufficient notice under all the Loan Documents,
     and the notice and cure periods provided in this Note and the other Loan
     Documents, if any be so provided, shall run concurrently and not
     consecutively. Time is of the essence of this Note.

     11. COSTS AND EXPENSES. If Payee retains the services of counsel in order
to enforce any remedy available to Payee under any document or instrument
evidencing or securing the Loan, attorney's fees as hereinbefore provided shall
be payable on demand by Maker to Payee, and Maker shall also pay on demand the
cost of any title search and all other costs incurred by Payee in connection
with proceedings to recover any sums due hereunder. Any such amounts not paid
promptly on demand shall be added to the outstanding principal balance of this
Note, shall bear interest at the Default Rate from the date of such demand until
paid in full and shall be secured by the Loan Documents. Maker shall also pay on
demand any reasonable recording and similar costs of Payee in connection with
the cancellation of this Note. Nothing contained in this Section ll shall
limit or impair the obligation of Maker to pay any and all costs and expenses
provided by law.

     12. NOTE TAXES, ETC. Maker shall pay the cost of any revenue and personal
property tax, tax, or other stamps now or hereafter required by the laws of the
Commonwealth of Pennsylvania, or the United States to be affixed to this Note.
If Maker does not or may not do so, Payee may at its option accelerate the
indebtedness evidenced by this Note to maturity as in the case of default by
Maker.

     13. INTEREST LIMITATIONS; SEVERABILITY.

          (a) Nothing herein contained nor any transaction related hereto shall
     be construed or shall operate either presently or prospectively to require
     Maker to pay interest at the rate greater than is now lawful in such case
     to contract for, but shall require payment of interest only to the extent
     of such lawful rate. Any interest paid in excess of the lawful rate shall
     be refunded to Maker. Such refund shall be made by application of the
     excessive amount of interest paid against any sums outstanding hereunder,
     and shall be applied in such order as Payee may determine. If the excessive
     amount of interest paid exceeds the sums outstanding hereunder, the portion
     exceeding the said sums outstanding hereunder shall be refunded in cash by
     Payee. Any such crediting or refund shall not cure or waive any default by
     Maker hereunder or under the other Loan Documents. Maker agrees, however,
     that in determining whether or not any interest payable hereunder exceeds
     the highest rate permitted by law, any non-principal payment (except
     payments specifically stated herein to be "interest"), shall be deemed, to
     the extent permitted by law, to be an expense, fee, premium, or penalty
     rather than interest.

          (b) In the event that for any reason one more of the provisions of
     this Note or their application to any person or circumstances shall be held
     to be invalid, illegal or unenforceable in any respect or to any extent,
     such provisions shall, to such extent, be held for naught as though not
     herein contained but shall nevertheless remain valid, legal and enforceable
     in all such other respects and to such extent as may be permissible. In
     addition, any such invalidity, illegality or unenforceability shall not
     affect any other provisions of this Note, but this Note shall be construed
     as if such invalid, illegal or unenforceable provisions had never been
     contained herein.

     14. NO JOINT VENTURE. Payee shall in no event be construed for any purpose
to be a partner, joint venture or associate of Maker or of any lessee, operator,
concessionaire, or licensee of Maker in the conduct of their respective
businesses.

     15. SUCCESSORS AND ASSIGNS. This Note inures to the benefit of Payee, his
heirs, personal representatives and assigns, and its binding upon Maker, its
successors, and assigns and the words "Payee" and "Maker" whenever used herein
shall be deemed and construed to include such respective personal
representatives successors, and assigns.

than one person or entity, the obligations and liabilities hereunder of each of
such persons and entities shall be joint and several and the word "Maker" shall
mean all or some of any of them. For purposes of this Note, the singular shall

in accordance with the laws of the Commonwealth of Pennsylvania. This Note may
only be amended by an instrument in writing signed by both Maker and Payee.

     20. SERIES OF NOTES. This Note is one of series of substantially identical
Notes issued by the Maker on even date herewith. Each individual Note entitles

charges in accordance with the amounts set forth in each individual Note. Each

respect to the Security Agreement set forth in Section 5. The declaration of an
Event of Default in any single Note shall be considered as an Event of Default
in all other Notes and the rights and remedies set forth in each Note shall be
applied on a pro-rata basis with respect to the relation between the principal
amount of each Note and the amount represented by the total of all of the
principal amounts of all Notes.

shall first be to repay Maker's revolving credit line outstanding with First
Service Bank of Doylestown, Pennsylvania account number 02-50060 in the

applied to fully repay the First Service Bank line shall be used for working
capital purposes by Maker. After the First Service Bank has been fully repaid,
Maker shall close the revolving credit line account.

     IN WITNESS WHEREOF, Maker, intending to be legally bound hereby, has caused
this Note to be duly executed, under seal, the date and year first above
written.

                                  Amendment #1
                                     to the
                          Promissory Note Dated 3-30-98
                                     made by
                     Cardiovascular Laboratories, Inc. of PA
                                       to
                              James W. Porter, Jr.


This Amendment #1 (hereinafter referred to as the "Amendment") to the Promissory
Note dated March 30, 1998 (hereinafter the "Note") between Cardiovascular
Laboratories, Inc. (hereinafter referred to as the "Maker") and James W. Porter,
Jr (hereinafter referred to as, the " Payee") is dated June 28, 1999.

WHEREAS Maker is unable, as of the date of this Amendment, to make payment on
the interest and principal as set forth in the Note; and Maker is thereby in
default of the terms and conditions set forth in the Note; and

WHEREAS Maker is entering into this Amendment to offer Payee incentive to
refrain from enforcing such remedies as the Payee is lawfully entitled to under
the terms of the Note; and

WHEREAS Payee wishes to retain its rights and remedies under the Note; and

WHEREAS Payee wishes to restructure Note to enhance the chance of obtaining
repayment of interest and principal of Note and to obtain such additional
payment as may be available under the terms of this Amendment.

NOW, THEREFORE, in consideration of their mutual covenants, and for other good
and valuable consideration, the receipt of which is hereby acknowledged, the
Parties hereto, intending to be legally bound, hereby agree to amend the Note as
follows:

1. Interest rate. In accordance with the terms of the Note, the interest rate on
the outstanding unpaid principal amount shall be increased to the Default Rate
(as defined in the original Note) of 11% per annum, which interest shall accrue
from April 1, 1999 until the Maker has paid the outstanding principal in its
entirety.

2. Principal and Interest Payment. Obligations under the Note shall remain
outstanding until repaid in their entirety. The final maturity of the Note shall
be extended to July 1, 2002, with twenty equal principal and interest payments
due on a monthly basis as set forth in Exhibit B. Additionally, any or all
outstanding principal and accrued but unpaid interest shall be eligible for
payment from the Payee's participation in the compensation plan of a proposed
network marketing organization organized to sell nutritional supplements
(hereinafter referred to as the ("NMO") as further described in this Amendment.

3. Current Interest Payments. Notwithstanding the provisions contained above in
Section 2 of this Amendment, Maker shall, in accordance with the provisions in
this Section 3, pay current interest at an 11% annualized rate on all
outstanding unpaid principal obligations


<PAGE>

under the Note and this Amendment. Such current interest payments shall begin
prior to the payment schedule set forth in Exhibit B to this Amendment under the
following conditions:

     A. Net Free Cash Flow Statements  Maker shall prepare a statement of net
     free cash flow on a quarterly basis showing the net free cash flows of
     Maker for each month in the preceding quarter and present such statements
     of net free cash flow to Payee no later than 30 days following the close of
     each calendar quarter. For the purposes of this Amendment, net free cash
     flow ("Net Free Cash Flow") shall mean the gross cash revenues received by
     the Maker during each month minus the gross cash payments made for expenses
     during each month.

     B. Current Interest Payments Once Maker's Net Free Cash Flow reaches $2,500
     or more for any calendar quarter, Maker shall become obligated to make
     interest payments to Payee on all outstanding principal amounts of the
     Note, as follows: First; all accrued interest payments up to the amount of
     the Net Free Cash Flow. Second, all current interest payments to the end of
     the last quarter.

4. Network Marketing Organization. Maker and its affiliates intend to launch a
NMO that will consist of the creation of a multi-level marketing distributor
sales force to sell nutritional supplements. Maker represents and Payee
expressly acknowledges that the NMO is not yet established, and may never become
successful enough to repay the principal, and interest on the Note,
Notwithstanding this fact, however, in an effort to induce the Payee not to
exercise all of its rights and remedies under the terms of the Note, Maker
offers the following additional incentive to Payee:

     A. Establishment of NMO. The establishment of NMO shall take place as soon
     as Maker is able to do so following the execution of this Amendment. Maker
     represents and Payee expressly acknowledges that the establishment and
     successful operation of the NMO is subject to inherent uncertainties,
     including, but not limited to, the inexperience of Maker in the
     establishment and operation of NMO's such as that contemplated by Maker.

     B. Establishment of the Compensation Plan. Maker represents and warrants to
     Payee that Maker shall ensure that NMO shall have a compensation plan (the
     "Compensation Plan") established to compensate distributors on retail sales
     of products made by distributors in the NMO. Such Compensation Plan shall
     form a means by which Payee may have all obligations of Maker fulfilled as
     well as affording Payee the opportunity to earn additional payments above
     the full amount of interest and principal due under the Notes as amended
     under terms set forth in this Amendment to compensate Payee for their
     forbearance in accepting the terms of this Amendment.

     C. NMO Compensation Plan With Respect to Payee. The Compensation Plan is
     intended to motivate and incentivize independent distributors to build
     their business through revenues generated within their downline multi-level
     organization of distributors. The Compensation Plan shall be structured to
     permit the Payee to be compensated at 25% of the Presidential Level of the
     Compensation Plan. The Presidential Level of the Compensation Plan shall
     consist of a 10% override on all net sales made by all distributors in the
     NMO. For the Purposes of this Amendment, net sales ("Net Sales")

Page 2 of 4

<PAGE>

     shall refer to all revenues generated by the NMO for the sale of retail
     products within the NMO minus any credits for returned merchandise, credit
     card processing fees, distributor commissions, distributor rebates and
     royalties. It is expressly represented by Maker and acknowledged by Payee
     that this Compensation Plan may require the recruitment of experienced NMO
     management and/or capital to launch and grow the NMO, and that such
     management or investors may insist on being considered as distributors for
     the purposes of calculating Net Sales under this agreement. It is expressly
     represented by Maker and acknowledged by Payee that the formation,
     operation and success of the NMO is highly dependent on Timothy W.
     Cunningham ("Cunningham") and that therefore the Compensation Plan shall
     consider Cunningham as a distributor for the purposes of calculating Net
     Sales, provided, however, that any compensation received by Cunningham from
     NMO retail sales shall not exceed 5% of the Net Sales unless the Payee has
     received in excess of $500,000 in cumulative payment from the Compensation
     Plan, at which time Cunningham's compensation from the NMO shall be subject
     to adjustment by the Board of Directors of Maker at whatever level such
     Board believes appropriate given the contribution of Cunningham to the
     success of the NMO enterprise.

5. Payee Agrees to Subordinate Notes to DVIBC, No Action. Payee agrees to
subordinate the Note to DVIBC in accordance with Exhibit A, and to execute
Exhibit A as evidence of such subordination. Additionally, the Payee agrees to
take no further action evidencing a default under the original terms of the Note
provided Maker complies with the terms of this Amendment in its entirety.

6. Descriptive Headings, Arbitration/Jurisdiction of the Court. The headings of
the several paragraphs of this Amendment are inserted for convenience only and
do not constitute a part of this Amendment, Any controversy or claim arising out
of or relating to this Amendment, or the breach thereof shall be settled by
arbitration in the County of Montgomery, Pennsylvania, USA, in accordance with
the rules of the American Arbitration Association there in effect, except that
the Parties thereto shall have any rights to discovery as would be permitted by
the Federal Rules of Civil procedure and the prevailing Party shall be entitled
to reasonable costs and reasonable attorney's fees from arbitration or any other
civil action. Judgement upon the a-ward rendered therein may be entered in any
Court having jurisdiction thereof Jurisdiction for any legal action is
stipulated between the Parties to lie in the County of Montgomery, Pennsylvania,
USA.

7. Partial Invalidity. In the event that one or more of the provisions contained
in this Amendment shall be held to be invalid, illegal or unenforceable in any
respect under any law, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.

8. Assignability. Except as otherwise provided herein, neither Party may assign
this Amendment or any right or obligation under this Amendment without the prior
written consent of the other Party, and any purported assignment without such
prior written consent shall be void and ineffective.

9. Notice. Any notice required or permitted herein shall be in writing and shall
be deemed to have been properly given if delivered personally, or if sent by

sent by international registered air mail, return

     liquidate by or on behalf of Maker:

          (g) The entry of any final, unappealable judgment against Maker in
     excess of Ten Thousand Dollars ($10,000) which remains unsatisfied for
     fifteen (15) days or the issuance of any attachment, tax lien, levy or
     garnishment in excess of Ten Thousand Dollars ($10,000) (except for
     carriers) against any property of material value in which Maker has an
     interest.

     7. DEFAULT RATE. Upon the occurrence of an Event of Default hereunder, the
interest rate otherwise payable under Section 2 hereof (the "Base Rate") shall

following entry of any judgment on or relating to this Note or the other Loan
Documents. Interest on any such judgment shall accrue and be payable at the

Documents, shall, at the option of the holder hereof, become immediately due
and payable, without presentation, demand or further action of any kind and

any and all rights and remedies available to Payee hereunder, or under any other
document executed in connection with the Loan or with respect to any collateral
pledged, mortgaged, or assigned a security therefor or otherwise available to
Payee at law or in equity. Maker agrees that any real estate that may be levied
upon pursuant to a judgment obtained by virtue hereof, on any writ of execution
issued thereon, may be sold upon any such writ in whole or in part in any order
described by Payee. The failure of the holder hereof to accelerate the
outstanding principal balance of the Loan upon the occurrence of an Event of
Default hereunder shall not constitute a waiver of such default or of the right
to accelerate the Loan at any time thereafter so long as the Event of Default
remains uncured.

     9. CONFESSION OF JUDGMENT. THE FOLLOWING PARAGRAPHS SET FORTH A WARRANT OF
ATTORNEY TO CONFESS JUDGMENT AGAINST MAKER. IN GRANTING THIS WARRANT OF
ATTORNEY, MAKER HEREBY KNOWINGLY, INTENTIONALLY AND VOLUNTARILY, AND ON THE
ADVICE OF ITS SEPARATE COUNSEL, UNCONDITIONALLY WAIVES ANY AND ALL RIGHTS WITH
RESPECT TO SUCH WARRANT THAT MAKER MAY HAVE PRIOR NOTICE TO PAYEE AND AN
OPPORTUNITY FOR HEARING UNDER THE CONSTITUTION AND LAWS OF THE UNITED STATES AND
THE COMMONWEALTH OF PENNSYLVANIA.

HEREUNDER, MAKE HEREBY IRREVOCABLY AUTHORIZED AND EMPOWERS ANY ATTORNEY OF
RECORD, OR THE PROTHONOTARY OR CLERK OF ANY COURT IN THE COMMONWEALTH OF
PENNSYLVANIA, OR ELSEWHERE, TO APPEAR FOR MAKER AT ANY TIME OR TIMES, IN ANY
SUCH COURT IN ANY ACTION BROUGHT AGAINST MAKER BY PAYEE WITH RESPECT TO THE
AGGREGATE AMOUNT PAYABLE HEREUNDER WITH OR WITHOUT DECLARATION FILED, AS OF ANY
TERM, AND THEREIN TO CONFESS OR ENTER JUDGMENT AGAINST MAKER FOR ALL SUMS
PAYABLE BY MAKER TO PAYEE HEREUNDER AS EVIDENCED BY AN AFFIDAVIT SIGNED BY A
DULY AUTHORIZED DESIGNEE OF PAYEE SETTING FORTH SUCH AMOUNT THEN DUE FROM MAKER

BUT IN NO EVENT LESS THAN FIVE THOUSAND DOLLARS ($5,000.00), WITH COSTS OF
SUIT, RELEASE OF PROCEDURAL ERRORS AND WITHOUT RIGHT OF APPEAL. IF A COPY OF
THIS NOTE, VERIFIED BY AFFIDAVIT, SHALL HAVE BEEN FILED IN SUCH ACTION, IT SHALL
NOT BE NECESSARY TO FILE THE ORIGINAL AS A WARRANT OF ATTORNEY, MAKER WAIVES THE
RIGHT TO ANY STAY OR EXECUTION AND THE BENEFIT OF ALL EXEMPTION LAWS NOW

                                       3
<PAGE>

OR HEREAFTER IN EFFECT. NO SINGLE EXERCISE OF THE FOREGOING WARRANT AND POWER TO
BRING ANY ACTION OR CONFESS JUDGMENT THEREIN SHALL BE DEEMED TO EXHAUST THE
POWER, BUT THE POWER SHALL CONTINUE UNDIMINISHED AND MAY BE EXERCISED FROM TIME
TO TIME AS OFTEN AS PAYEE SHALL ELECT UNTIL ALL AMOUNTS PAYABLE TO PAYEE
HEREUNDER SHALL HAVE BEEN PAID IN FULL.

     10. WAIVERS BY MAKER, CUMULATIVE REMEDIES, ETC.

          (a) Maker hereby waives the benefit of any laws which now or hereafter
     might otherwise authorize the stay of any execution to be issued on any
     judgment recovered on this Note, or the exemption of any, property from
     levy, attachment and sale thereunder. Maker waives and releases unto the
     holder hereof and said attorney all errors, defects and imperfections
     whatsoever of a procedural nature in the entering of the said judgment or
     any process or proceedings relating hereto. Maker waives the right of
     inquisition on all real estate, voluntarily condemns it, and agrees that
     the real estate may be sold on writ of execution. MAKER HEREBY WAIVES ITS
     RIGHTS TO TRIAL BY JURY IN CONNECTION WITH THE ENFORCEMENT OF THIS NOTE OR
     ANY OTHER LOAN DOCUMENT IN ANY LEGAL PROCEEDINGS ARISING HEREUNDER OR
     THEREUNDER.

          (b) Maker and all endorsers of this obligation severally waive
     presentment, demand, protest and notice of nonpayment. Maker and the
     endorsers hereof and sureties therefor, if any, and all others who may be
     liable for all or any part of the indebtedness evidenced by this Note,
     consent to any number of renewals or extensions of the time of payment
     hereof without notice to any of those parties. The granting, without
     notice, of any extension of time for the payment of any sum due under this
     Note or for the performance of any covenant, condition or agreement hereof
     of thereof or the taking or release of other or additional security shall
     in no way release or discharge the liability of Maker or of any such
     endorsers or sureties.

          (c) No right or remedy conferred upon or served to Payee hereunder or
     under any other document evidencing or securing the Loan, or with respect
     to any guaranty or any collateral securing the Loan, or now or hereafter
     existing at law or in equity or by statute or other legislative enactment,
     is intended to be exclusive of any other right or remedy, and each and
     every such right and remedy shall be cumulative and concurrent, and shall
     be in addition to every other such right and remedy, and may be pursued
     singly, concurrently, successively or otherwise, at the sole discretion of
     Payee, and shall not be exhausted by any one exercise thereof but may be
     exercised as often as occasion therefor shall occur. No act of Payee shall
     be deemed or construed as an election to proceed under any one such right
     or remedy the exclusion of any other such right or remedy; furthermore,
     each such right and remedy of Payee shall be separate, distinct and
     cumulative, and none shall be given effect to the exclusion of any other to
     exercise or delay in exercising any such right or remedy, or the failure to
     insist upon strict performance of any term of any of such documents, shall
     not be construed as a waiver or release of the same, or of any Event of
     Default, or any obligation or liability of Maker thereunder, nor shall
     Payee be deemed, by any act of omission or commission, to have waived any
     of its rights or remedies hereunder unless such waiver is in writing and
     signed by Payee and when only to the extent specifically set forth in the
     writing. A waiver as to one event shall not be construed as continuing or a
     bar to or waiver of any right or remedy as to a subsequent event.

          (d) The recovery of any judgment by Payee and/or the levy of execution
     under any judgment upon any collateral for the Loan shall not effect in any
     manner or to any extent the lien of any security interest in any such
     collateral, or any rights, remedies or powers of Payee under any documents
     evidencing or securing the Loan or with respect to any guaranty or any
     such collateral, but such lien and security interests and rights, remedies
     and powers of Payee shall continue unimpaired as before. The exercise by
     Payee of its rights and remedies and the entry of any judgment by payee
     shall not affect in any way the interest rate payable hereunder or any
     amounts due to Payee but interest shall continue to accrue on such amounts
     at the rate specified herein.

          (e) Maker agrees that any action or proceeding against it to enforce
     this Note may be commenced in the appropriate Court and Maker waives
     personal service process and agrees that a summons and complaint commencing
     an action or proceeding in any such court shall be properly served

                                       4
<PAGE>


     and shall confer personal jurisdiction if served by registered or certified
     mail in accordance with the notice provisions set forth herein.

          (f) The delivery of notice under this Note or under any other loan
     document shall constitute sufficient notice under all the Loan Documents,
     and the notice and cure periods provided in this Note and the other Loan
     Documents, if any be so provided, shall run concurrently and not
     consecutively. Time is of the essence of this Note.

     11. COSTS AND EXPENSES. If Payee retains the services of counsel in order
to enforce any remedy available to Payee under any document or instrument
evidencing or securing the Loan, attorney's fees as hereinbefore provided shall
be payable on demand by Maker to Payee, and Maker shall also pay on demand the
cost of any title search and all other costs incurred by Payee in connection
with proceedings to recover any sums due hereunder. Any such amounts not paid
promptly on demand shall be added to the outstanding principal balance of this
Note, shall bear interest at the Default Rate from the date of such demand until
paid in full and shall be secured by the Loan Documents. Maker shall also pay on
demand any reasonable recording and similar costs of Payee in connection with
the cancellation of this Note. Nothing contained in this Section ll shall
limit or impair the obligation of Maker to pay any and all costs and expenses
provided by law.

     12. NOTE TAXES, ETC. Maker shall pay the cost of any revenue and personal
property tax, tax, or other stamps now or hereafter required by the laws of the
Commonwealth of Pennsylvania, or the United States to be affixed to this Note.
If Maker does not or may not do so, Payee may at its option accelerate the
indebtedness evidenced by this Note to maturity as in the case of default by
Maker.

     13. INTEREST LIMITATIONS; SEVERABILITY.

          (a) Nothing herein contained nor any transaction related hereto shall
     be construed or shall operate either presently or prospectively to require
     Maker to pay interest at the rate greater than is now lawful in such case
     to contract for, but shall require payment of interest only to the extent
     of such lawful rate. Any interest paid in excess of the lawful rate shall
     be refunded to Maker. Such refund shall be made by application of the
     excessive amount of interest paid against any sums outstanding hereunder,
     and shall be applied in such order as Payee may determine. If the excessive
     amount of interest paid exceeds the sums outstanding hereunder, the portion
     exceeding the said sums outstanding hereunder shall be refunded in cash by
     Payee. Any such crediting or refund shall not cure or waive any default by
     Maker hereunder or under the other Loan Documents. Maker agrees, however,
     that in determining whether or not any interest payable hereunder exceeds
     the highest rate permitted by law, any non-principal payment (except
     payments specifically stated herein to be "interest"), shall be deemed, to
     the extent permitted by law, to be an expense, fee, premium, or penalty
     rather than interest.

          (b) In the event that for any reason one more of the provisions of
     this Note or their application to any person or circumstances shall be held
     to be invalid, illegal or unenforceable in any respect or to any extent,
     such provisions shall, to such extent, be held for naught as though not
     herein contained but shall nevertheless remain valid, legal and enforceable
     in all such other respects and to such extent as may be permissible. In
     addition, any such invalidity, illegality or unenforceability shall not
     affect any other provisions of this Note, but this Note shall be construed
     as if such invalid, illegal or unenforceable provisions had never been
     contained herein.

     14. NO JOINT VENTURE. Payee shall in no event be construed for any purpose
to be a partner, joint venture or associate of Maker or of any lessee, operator,
concessionaire, or licensee of Maker in the conduct of their respective
businesses.

     15. SUCCESSORS AND ASSIGNS. This Note inures to the benefit of Payee, his
heirs, personal representatives and assigns, and its binding upon Maker, its
successors, and assigns and the words "Payee" and "Maker" whenever used herein
shall be deemed and construed to include such respective personal
representatives successors, and assigns.

     16. NOTICES. All notices required to be given to any of the parties
hereunder shall be in writing and shall be deemed to have been sufficiently
given for all purposes when presented personally to such party or sent by
certified or registered mail, return receipt requested, or by courier service
with guaranteed overnight delivery, addressed to such party at its address as
set forth in the beginning of this Note. Such notice shall be deemed to be given
when received if delivered personally, or two (2) days after the date deposited
with the United States Postal Service if sent by certified or registered mail,
return receipt requested, or one (1) day after the same is delivered to a
courier service with guaranteed overnight delivery. Any notice of any change in
such address shall also be given in the manner set forth above. Whenever the
giving of notice is required, the giving of such notice may be waived in writing
by the party entitled to receive such notice.

     17. DEFINITIONS; NUMBER AND GENDER. In the event Maker consists of more
than one person or entity, the obligations and liabilities hereunder of each of
such persons and entities shall be joint and several and the word "Maker" shall
mean all or some of any of them. For purposes of this Note, the singular shall
be deemed to include the plural and the neuter shall be deemed to include the
masculine and feminine, as the context may require.

     18. CAPTIONS. The captions or headings of the sections of this Note are for
convenience only and shall not control or affect the meaning or construction of
any of the terms or provisions of this Note.

     19. GOVERNING LAW; AMENDMENT. This Note shall be governed by and construed
in accordance with the laws of the Commonwealth of Pennsylvania. This Note may
only be amended by an instrument in writing signed by both Maker and Payee.

     20. ADDITIONAL CONSIDERATION; ISSUANCE OF SHARES OF MAKER. In addition to
the payment of all sums due under this Note to Payee, as additional
consideration to Payee for making the Loan to Maker, Maker agrees to issue to
Payee at the closing of this Loan that number of non-restricted and
freely-traded shares of common stock of Maker equal in value to the amount of
the principal due hereunder.

     21. SERIES OF NOTES. This Note is one of a series of substantially
identical Notes issued by the Maker on even date herewith. Each individual Note
entitles the Note's Payee to all rights of payment of interest, principal and
late charges in accordance with the amounts set forth in each individual Note.
Each Note shall rank on a pari pasu and pro-rata basis with all other Notes with
respect to the Security Agreement set forth in Section 5. The declaration of an
Event of Default in any single Note shall be considered as an Event of Default
in all other Notes and the rights and remedies set forth in each Note shall be
applied on a pro-rata basis with respect to the relation between the principal
amount of each Note and the amount represented by the total of all of the
principal amounts of all Notes.

     22. USE OF PROCEEDS. The use of the proceeds from the issuance of all Notes
shall first be to repay Maker's revolving credit line outstanding with First
Service Bank of Doylestown, Pennsylvania account number 02-50060 in the
approximate amount of $122,603. Any proceeds in excess of this amount not
applied to fully repay the First Service Bank line shall be used for working
capital purposes by Maker. After the First Service Bank has been fully repaid,
Maker shall close the revolving credit line account.

     IN WITNESS WHEREOF, Maker, intending to be legally bound hereby, has caused
this Note to be duly executed, under seal, the date and year first above
written.

                                     to the
                          Promissory Note Dated 3-30-98
                                     made by
                     Cardiovascular Laboratories, Inc. of PA
                                       to
                                F. Stanton Moyer

This Amendment #1 (hereinafter referred to as the "Amendment") to the Promissory
Note dated March 30, 1998 (hereinafter the "Note") between Cardiovascular
Laboratories, Inc. (hereinafter referred to as the "Maker") and F. Stanton Moyer
(hereinafter referred to as, the "Payee") is dated June 10, 1999.

WHEREAS Maker is unable, as of the date of this Amendment, to make payment on
the interest and principal as set forth in the Note; and Maker is thereby in
default of the terms and conditions set forth in the Note; and

WHEREAS Maker is entering into this Amendment to offer Payee incentive to
refrain from enforcing such remedies as the Payee is lawfully entitled to under
the terms of the Note; and

WHEREAS Payee wishes to retain its rights and remedies under the Note; and

WHEREAS Payee wishes to restructure Note to enhance the chance of obtaining
repayment of interest and principal of Note and to obtain such additional
payment as may be available under the terms of this Amendment.

NOW, THEREFORE, in consideration of their mutual covenants, and for other good
and valuable consideration, the receipt of which is hereby acknowledged, the
Parties hereto, intending to be legally bound, hereby agree to amend the Note as
follows:

1. Interest rate. In accordance with the terms of the Note, the interest rate on
the outstanding unpaid principal amount shall be increased to the Default Rate
(as defined in the original Note) of 11% per annum, which interest shall accrue
from April 1, 1999 until the Maker has paid the outstanding principal in its
entirety.

2. Principal and Interest Payment. Obligations under the Note shall remain
outstanding until repaid in their entirety. The final maturity of the Note shall
be extended to July 1, 2002, with twenty equal principal and interest payments
due on a monthly basis as set forth in Exhibit B. Additionally, any or all
outstanding principal and accrued but unpaid interest shall be eligible for
payment from the Payee's participation in the compensation plan of a proposed
network marketing organization organized to sell nutritional supplements
(hereinafter referred to as the ("NMO") as further described in this Amendment.

3. Network Marketing Organization. Maker and its affiliates intend to launch a
NMO that will consist of the creation of a multi-level marketing distributor
sales force to sell nutritional supplements. Maker represents and Payee
expressly acknowledges that the NMO is not yet established, and may never become
successful enough to repay the principal, and interest on the


<PAGE>


Note. Notwithstanding this fact, however, in an effort to induce the Payee not
to exercise all of its rights and remedies under the terms of the Note, Maker
offers the following additional incentive to Payee:

          A. Establishment of NMO. The establishment of NMO shall take place as
     soon as Maker is able to do so following the execution of this Amendment.
     Maker represents and Payee expressly acknowledges that the establishment
     and successful operation of the NMO is subject to inherent uncertainties,
     including, but not limited to, the inexperience of Maker in the
     establishment and operation of NMO's such as that contemplated by Maker.

          B. Establishment of the Compensation Plan. Maker represents and
     warrants to Payee that Maker shall ensure that NMO shall have a
     compensation plan (the "Compensation Plan") established to compensate
     distributors on retail sales of products made by distributors in the NMO.
     Such Compensation Plan shall form a means by which Payee may have all
     obligations of Maker fulfilled as well as affording Payee the opportunity
     to earn additional payments above the full amount of interest and principal
     due under the Notes as amended under terms set forth in this Amendment to
     compensate Payee for their forbearance in accepting the terms of this
     Amendment.

          C. NMO Compensation Plan With Respect to Payee. The Compensation Plan
     is intended to motivate and incentivize independent distributors to build
     their business through revenues generated within their downline multi-level
     organization of distributors. The Compensation Plan shall be structured to
     permit the Payee to be compensated at 25% of the Presidential Level of the
     Compensation Plan. The Presidential Level of the Compensation Plan shall
     consist of a 10% override on all net sales made by all distributors in the
     NMO. For the Purposes of this Amendment, net sales ("Net Sales") shall
     refer to all revenues generated by the NMO for the sale of retail products
     within the NMO minus any credits for returned merchandise, credit card
     processing fees, distributor commissions, distributor rebates and
     royalties. It is expressly represented by Maker and acknowledged by Payee
     that this Compensation Plan may require the recruitment of experienced NMO
     management and/or capital to launch and grow the NMO, and that such
     management or investors may insist on being considered as distributors for
     the purposes of calculating Net Sales under this agreement. It is expressly
     represented by Maker and acknowledged by Payee that the formation,
     operation and success of the NMO is highly dependent on Timothy W.
     Cunningham ("Cunningham") and that therefore the Compensation Plan shall
     consider Cunningham as a distributor for the purposes of calculating Net
     Sales, provided, however, that any compensation received by Cunningham from
     NMO retail sales shall not exceed 5% of the Net Sales unless the Payee has
     received in excess of $500,000 in cumulative payment from the Compensation
     Plan, at which time Cunningham's compensation from the NMO shall be subject
     to adjustment by the Board of Directors of Maker at whatever level such
     Board believes appropriate given the contribution of Cunningham to the
     success of the NMO enterprise.

4. Payee Agrees to Subordinate Notes to DVIBC, No Action. Payee agrees to
subordinate the Note to DVIBC in accordance with Exhibit A, and to execute
Exhibit A as evidence of such subordination. Additionally, the Payee agrees to
take no further action evidencing a default under

                                       2
<PAGE>

the original terms of the Note provided Maker complies with the terms of this
Amendment in its entirety.

5. Descriptive Headings, Arbitration/Jurisdiction of the Court. The headings of
the several paragraphs of this Amendment are inserted for convenience only and
do not constitute a part of this Amendment. Any controversy or claim arising out
of or relating to this Amendment, or the breach thereof, shall be settled by

the rules of the American Arbitration Association there in effect, except that
the Parties thereto shall have any rights to discovery as would be permitted by

to reasonable costs and reasonable attorney's fees from arbitration or any other
civil action. Judgement upon the award rendered therein may be entered in any
Court having jurisdiction thereof. Jurisdiction for any legal action is
stipulated between the Parties to lie in the County of Montgomery, Pennsylvania,
USA.

6. Partial Invalidity. In the event that one or more of the provisions contained
in this Amendment shall be held to be invalid, illegal or unenforceable in any
respect under any law, the validity, legality and enforceability of the
remaining provisions contained herein shall not in any way be affected or
impaired thereby.

7. Assignability. Except as otherwise provided herein, neither Party may assign
this Amendment or any right or obligation under this Amendment without the prior
written consent of the other Party, and any purported assignment without such
prior written consent shall be void and ineffective.

8. Notice. Any notice required or permitted herein shall be in writing and shall
be deemed to have been properly given if delivered personally, or if sent by
facsimile (with a copy mailed by international air mail or U.S. mail), or if
sent by international registered air mail, return receipt requested, or if sent

9. Entire Amendment/Counterparts. This Amendment constitutes the entire
amendment to the Note as agreed upon between the Parties and cancels and
supersedes any and all existing agreements or arrangements to amend the note by
and between Payee and Maker relating to the subject matter hereof, whether
written or oral, and all such prior agreements or arrangements are hereby deemed

              EXHIBIT A TO AMENDMENT TO NOTE DATED MARCH 30, 1998


                             SUBORDINATION AGREEMENT

This Subordination Agreement ("Agreement") is made and entered into __________,
1999 between F. Stanton Moyer (hereinafter collectively and individually
referred to as the "Subordinated Creditor"), Cardiovascular Laboratories, Inc.
of PA ("Debtor"), and DVI Business Credit Corporation ("DVIBC"). RECITALS

WHEREAS, Debtor is indebted to Subordinated Creditor; and

WHEREAS, Debtor desires to obtain leases, loans, extensions of credit, and other
financial services from DVIBC; and

WHEREAS, DVIBC is unwilling to extend credit or provide financial services to
Debtor unless Debtor and Subordinated Creditor enters into this Agreement with
DVIBC.

NOW, THEREFORE, for value received and in consideration of the mutual covenants
herein, and to induce DVIBC to extend credit and provide financial services to
Debtor, the parties hereto intend to be legally bound, hereby, do agree as
follows:

                                    AGREEMENT

     1. For the purposes of this Agreement the following definitions shall
apply:

     1.1 "Junior Debt" means all loans, advances, liabilities, debit balances,
covenants and duties at any time owed by Debtor to Subordinated Creditor,
whether direct or indirect, absolute or contingent, secured or unsecured, due or
to become due, now existing or hereafter arising, and whether created directly
or acquired indirectly by assignment, pledge, purchase or otherwise and whether
arising in connection with creditors, shareholders, directors or officers'
rights or other rights to distributions, dividends, salaries, bonuses, loan
payments, note payments, professional fees, management fees, or compensation of
any nature whether matured or not, together with all interest, fees, charges,
expenses and attorneys' fees for which Debtor is now or hereafter becomes liable
to pay to Subordinated Creditor under any agreement or by law.

     1.2 "Senior Debt" means all loans, advances, liabilities, debit balances,
covenants and duties at any time owed by Debtor to DVIBC, whether direct or
indirect, absolute or contingent, secured or unsecured, due or to become due,
now existing or hereafter arising, including without limitation any debt,
liability or obligation owing from Debtor to others which DVIBC may have
obtained by assignment, pledge, purchase or otherwise, together with all
interest, fees, charges, expenses and attorneys' fees for which Debtor is now or
hereafter becomes liable to pay to DVIBC under any agreement or by law, and
including all deferrals, renewals, extensions, refundings and refinancings, in
whole or in part of any of the foregoing.

     2. Subordinated Creditor hereby postpones and subordinates, to the extent
and in the manner provided in this Agreement, all of the Junior Debt, to the
payment of all of the Senior Debt. If Debtor issues or has issued any instrument
or document evidencing the Junior Debt, each such instrument and document
shall bear a conspicuous legend that it is subordinated to the Senior Debt. All
instruments and documents evidencing the Junior Debt shall upon request be
delivered DVIBC properly assigned or endorsed to DVIBC.

     3. Subordinated Creditor agrees not to sue upon, or to collect, or to
receive payment upon, by setoff in any other manner, the Junior Debt, now or
hereafter existing, nor to sell, assign, transfer, pledge, or give a security
interest in the Junior Debt (except subject expressly to this Agreement), nor to
enforce or apply any security now or hereinafter existing, nor to join in any
petition to bankruptcy or any assignment for the benefit of creditors, or any
creditors agreement, not to take any lien or security on Debtor's property real
or personal, nor to incur any obligations nor to receive distributions except as
provided in Section 4 below, any lows, advances or gifts from Debtor, so long as
any Senior Debt shall exist or so long as DVIBC is committed or otherwise
obligated to make any loan to or grant any credit to Debtor.

     4. All Senior Debt now or hereafter existing shall be first paid by Debtor
before any payment shall be made by Debtor to Subordinated Creditor on the
Junior Debt; provided, however that so long as (a) no Event of Default, or any
event which with the giving of notice or lapse of time (or both) would
constitute an Event of Default (as defined in any agreement evidencing any
Senior Debt) exists with respect to any Senior Debt; or (b) such payment will
not cause such an Event of Default, or otherwise render Debtor unable to pay the
Senior Debt, Debtor may pay valid claims owing to Subordinated Creditor incurred
in the ordinary course of business in accordance with the terms of that certain
Promissory Note of Debtor payable to Subordinated Creditor in the original
principal amount of $50,000, dated as of March 30, 1998 (which shall not be
modified without DVIBC's written consent thereto), but not by prepayment,
acceleration or otherwise.

     5. The priority of payment set forth in Section 4 above shall apply during
the ordinary course of Debtor's business and in case of any assignment by Debtor
for the benefit of Debtor's creditors, and in case of any bankruptcy proceedings
instituted by or against Debtor's assets, and in case of any dissolution or
other winding up of the affairs of Debtor, or of Debtor's business, and in all
such cases respectively, the officers of Debtor and any assignee, trustee in
bankruptcy, receiver, and other person or persons in charge are hereby

                                        1

<PAGE>

directed to pay DVIBC the full amount of any Senior Debt before making any
payments to Subordinated Creditor, and so far as may be necessary for that
purpose, Subordinated Creditor hereby transfers, assigns and grants to DVIBC a
security interest in all of its interests and rights in and to the Junior Debt.

     6. If Debtor defaults at any time under any agreement evidencing any Senior
Debt, and if Debtor has at any time from the inception of any such agreement
made any payment to Subordinated Creditor, Subordinated Creditor will be fully
liable for any and all loss or damage incurred by DVIBC as a result of Debtor's
default under such agreement up to the amount of any and all payments received
by Subordinated Creditor. DVIBC is hereby irrevocably constituted and appointed
the attorney-in-fact of Subordinated Creditor to file any and all proofs of
claim and any other documents and to take all other action, either in DVIBC's
name, or in the name of the Subordinated Creditor, which in DVIBC's opinion is
necessary or desirable to enable DVIBC to obtain such payments.

     7. No subordination of any Junior Debt has previously been executed by
Subordinated Creditor for the benefit of anyone else and any such subordinations
hereafter executed will be and shall be expressed to be subject and subordinate
to the effect hereof. This Agreement shall be continuing in effect, it shall not
be cancelled or otherwise rendered ineffective by the payment or discharge at
any time of the Senior Debt, and it shall apply to any and all Senior Debt
subsequently granted, renewed or extended by DVIBC for Debtor, unless
Subordinated Creditor shall deliver to DVIBC a written notice of revocation as
to future transactions at a time when Debtor is no longer obligated to DVIBC in
any way and while DVIBC is not committed to or otherwise obligated to make any
leases, loans or other financial accommodations to Debtor.

     8. Subordinated Creditor hereby further agrees that Subordinated Creditor
shall not permit Debtor to: (i) make payment to any of the other parties
constituting a relative, affiliate or related in any way to Subordinated
Creditor contrary to the terms of this Agreement, including, without limitation,
payment of any distribution, professional fees, salary, bonus or other form of
compensation to Subordinated Creditor; and (ii) make payment to any other party
other than DVIBC in satisfaction of any Senior Debt and any other obligations as
may be owing to DVIBC from time to time except as may otherwise be consented to
by DVIBC in writing.

     9. THE CONSTRUCTION, INTERPRETATION, VALIDITY AND ENFORCEABILITY OF THIS
AGREEMENT SHALL BE GOVERNED IN ALL RESPECTS BY THE LAWS OF THE STATE OF
CALIFORNIA. SUBORDINATED CREDITOR AGREE TO SUBMIT TO THE JURISDICTION AND VENUE
OF THE STATE AND THE FEDERAL COURTS IN CALIFORNIA. In any action, suit,
arbitration, or mediation relating to the enforcement of this Agreement the
prevailing party shall be entitled to recover its costs and expenses including
reasonable attorneys' fees.

     10. This Agreement may be signed in any number of counterparts, each of
which will constitute an original, and all of which, taken together, shall
constitute but one and the same agreement.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly
executed as of the date first written.

                                      LOAN

     Section 2.1. The Loan Subject to the terms and conditions and relying on
the representations and warranties set forth herein, Lender agrees to make
Advances to Borrower from time to time in an aggregate amount not to exceed the
lesser of (i) One Million Dollars ($ 1,000,000) (the "Commitment Amount"), or
(ii) the Borrowing Base. Within the limits of the Loan Availability, Borrower
may borrow, make repayments pursuant to Section 2.4 and reborrow. If, at any
time, the aggregate Advances and other Obligations outstanding exceed the then
Loan Availability, then Borrower shall pay to Lender a sum sufficient to reduce
the Advances and other Obligations outstanding to an amount not greater than the
Loan Availability. Lender's commitment to make Advances shall expire, and the
amount of the Loan then outstanding shall mature and be repaid by Borrower,
without further action on the part of Lender, on the Termination Date.

     Section 2.2. Note All Loans made by the Lender under this Agreement shall
be evidenced by, and repaid with interest in accordance with, a single
promissory note of Borrower in substantially the form of Exhibit B duly
completed, in the original principal amount equal to the initial Commitment
Amount, dated the Effective Date, payable to the Lender and maturing as to
principal on the Termination Date (the "Note"). The amount of each Advance and
payment of principal amount received by the Lender shall be recorded in the
books and records of the Lender, which books and records shall, in the absence
of manifest error, be conclusive as to the outstanding balance of and other
information related to the Loan. Lender shall be entitled at any time to endorse
on a schedule attached to the Note the amount and type of each Advance and
information relating thereto.

     Section 2.3. The Borrowing Base On a weekly basis the Borrowing Base will
be recalculated by adding weekly billings to the prior week's Eligible Accounts
and subtracting deposits and adjustments, if applicable, and then multiplying
this amount by the Net Collectible Percentage. The Borrowing Base shall be
calculated on the basis of the reports delivered to Lender pursuant to Section
5.4.

     Section 2.4. Notice of Borrowing Whenever Borrower desires to borrow under
Section 2.1, Borrower shall deliver to Lender a Drawdown Request Form, in a form
reasonably satisfactory to Lender, signed by an authorized officer no later than
2:00 p.m. Pacific Standard Time at least one (1) business day in advance of the
proposed funding date. The Drawdown Request Form shall specify (i) the funding
date (which shall be a business day) with respect to the requested Loan and (ii)
the amount of the proposed Advance.

     Section 2.5. Use of Proceeds The proceeds of the Loan shall be used by
Borrower to payoff an existing debt with Prime Bank and to provide working
capital.

     Section 2.6. Loan Repayment Via Lock Box/Servicer Account. Upon the
execution hereof, Borrower shall become a party to the Lock Box Agreement which
provides for the receipt and processing of Account payments. Borrower shall
irrevocably direct: (i) all nongovernment payors to remit payment to the
Servicer's post office box in Lender's name and control, and (ii) all government
payors to remit payment to a second post office box of such Servicer in
Borrower's name. Prior to funding and upon receipt of the lock box post office
box number(s), Borrower shall provide Lender re-direct letters (in a form
satisfactory to Lender) to all of Borrower's payors on Borrower's letterhead,
including envelopes for Lender to process and mail (Lender will add postage
which shall be charged to Borrower). The Lock Box Agreement provides for the
Servicer to deposit daily all receipts of the post office boxes into deposit
accounts, with non-government payor receipts paid into an account subject to
Lender's control and, government payor receipts paid into an account in
Borrower's name; such accounts shall be (i) at a financial institution
acceptable to Lender, and (ii) governed by terms and conditions acceptable to
Lender. Borrower agrees and acknowledges that all government payor receipts will
be immediately transferred to an account in the name and control of Lender. Upon
collectibility, deposits (net of fees) shall be applied to reduce the Loan
balance including Advances, interest, fees, all charges and other payments, if
applicable. Deposits/receipts will reduce the Borrowing Base in accordance with
Section 2.3 above. Any receipts (net of such Servicer's fees) remaining after
all such payments to Lender will be paid to Borrower within 24 hours of
availability. Borrower shall bear all charges for establishing and maintaining
the post office box accounts and all bank charges for such deposit accounts.
Lender shall deduct from the deposit accounts all sums Borrower owes to it
hereunder, including fees, interest, reimbursements and principal payments. Any
Obligations not paid by such deduction shall be satisfied by direct payment to
Lender at 4041 MacArthur Blvd., Suite 401, Newport Beach, California 92660. Any
amounts hereunder not paid as agreed shall be assessed a late payment penalty of
five percent (5%).

     Section 2.7. Term of Agreement. The term of this Agreement is two (2) years
from the Effective Date ("Initial Term") and is non-cancelable. This Agreement
shall be renewed for consecutive one (1) year terms ("Additional Term") unless
this Agreement is terminated, effective as of the last day of a term, by written
notice by Lender or Borrower no later than thirty (30) days before the
expiration of such term. All of Lender's obligations, responsibilities and
duties shall cease upon the date of termination of this Agreement, except for
its obligation to remit excess receipts from the lock box deposit accounts in
accordance with the terms of this Agreement. To the extent this Agreement is
renewed after the Initial Term, regardless of the length of the renewal period,
Borrower shall pay Lender a renewal fee equal to one percent (1.0%) of the
Commitment Amount at the time of the renewal.

     Section 2.8. Lender's Fees Upon execution hereof, Lender shall be entitled
to an origination fee equal to one percent (1.0%) of the Commitment Amount, less
$7,500 currently on deposit. Increases to the Commitment Amount during the term
will be charged on the incremental increase at the same origination percentage.
On or before the first day of each month following the Effective Date, Borrower
shall pay Lender a monthly maintenance fee of Eight Hundred Fifty Dollars
($850). Increases to the Commitment Amount during the term will be charged an
incremental increase in the monthly maintenance fee proportionate to the
percentage increase in the Commitment Amount, On or before the first day of each
month following the Effective Date, Borrower shall pay Lender an unutilized loan
fee equal to one half of one percent (.50%) of the difference between the
Commitment Amount and the average outstanding Loan amount as of the previous
month. Lender's fees will be deducted, when due, directly from receipts
deposited accordance with Section 2.6. Unutilized loan fee equal to .50% per
year.

equal to Five Hundred Dollars ($500) per auditor per day plus out of pocket
expenses for each audit of Borrower performed by Lender subsequent to the

Section 2.10. Interest on the Loans All Advances shall bear interest on the
unpaid principal amount thereof from the date made until paid in full at a
fluctuating rate equal to the Reference Rate plus three percent (3.0%) per


                                        5

month for the preceding month. Interest shall be calculated on the basis of a
year of 360 days, but for the actual number of days elapsed. Interest accrued

all other documents Lender may reasonably request, in form satisfactory to
Lender, to perfect and maintain perfected Lender's Liens in the Collateral and
in order to consummate fully all of the transactions contemplated under the Loan
Documents. Borrower hereby irrevocably makes, constitutes and appoints Lender
(and any of Lender's officers, employees or agents designated by Lender) as

     Section 7.2. Lender's Duty of Care Lender shall have no duty of care with
respect to the Collateral except that Lender shall exercise reasonable care with
respect to the Collateral in Lender's custody. Lender shall be deemed to have
exercised reasonable care if such property is accorded treatment substantially
equal to that which Lender accords its own property or if Lender takes such
action with respect to the Collateral as Borrower shall request or agree to in
writing provided that neither failure to comply with any such request nor any
omission to do any such act requested by Borrower shall be deemed a failure to
exercise reasonable care. Lender's failure to take steps to preserve rights
against any parties or property shall not be deemed to be failure to exercise
reasonable care with respect to the Collateral in Lender's custody. All risk,
loss, damage or destruction of the Collateral shall be borne by Borrower.

     Section 7.3. Reinstatement of Liens If, at any time after payment in full

by Lender for any reason whatsoever (including, without limitation, the
insolvency, bankruptcy, or reorganization of Borrower or such other Person),

hereof, (i) to pay any moneys (whether taxes, assessments, insurance premiums or
otherwise) due to third persons or entities, (ii) to make any deposits or

not permitted hereby, then Lender may, to the extent that it determines that
such failure by Borrower could have a material adverse effect on Lender's
interests in the Collateral, in its discretion and without prior notice to
Borrower, make payment of the same or any part thereof. Any amounts paid or
deposited by Lender shall constitute Lender Expenses, shall become part of the
Obligations, shall bear interest at the rate of eighteen percent (18%) per
annum, and shall be secured by the Collateral. Any payments made by Lender shall
not constitute (a) an agreement by Lender to make similar payments in the future
or (b) a waiver by Lender of any Event of Default under this Agreement. Lender
need not inquire as to, or contest the validity of, any such expense, tax,
security interest, encumbrance or Lien and the receipt of the usual official
notice for the payment of moneys to a governmental entity shall be conclusive
evidence that the same was validly due and owing


                                       10

waives the right to assert a confidential relationship, if any, it may have with
any accounting firm or service bureau in connection with any information
requested by Lender pursuant to this Agreement and agrees that Lender may
directly contact any such accounting firm or service bureau in order to obtain
such information.

     Section 11.2. Power of Attorney Borrower hereby appoints Lender (and any of
Lender's officers, employees, or agents designated by Lender) as Borrower's

orders, drafts or other forms of payment or security that may come into Lender's

Obligations are outstanding. Lender agrees not to exercise the power granted in
clause 11.2(b) prior to the occurrence of an Event of Default and agrees not to
exercise the power granted in clause 11.2(d) prior to notification of Borrower
of its intent to do so, but such limitations do no limit the effectiveness of
such power of attorney at any time. Any person dealing with Lender shall be
entitled to rely conclusively on any written or oral statement of Lender that
this power of attorney is in effect. Lender may also use Borrower's stationery
in connection with exercising its rights and remedies and performing the
Obligations of Borrower.

     Section 11.3. Expenses Secured All expenses, including attorney fees,
incurred by Lender in the exercise of its rights and remedies provided in this
Agreement, in the other Loan Documents or by law shall be payable by Borrower to
Lender, shall be part of the Obligations, and shall be secured by the
Collateral.

     Section 11.4. Equitable Relief Borrower recognizes that in the event
Borrower fails to perform, observe, or discharge any of its Obligations or
liabilities under this Agreement, no remedy of law will provide adequate relief
to Lender, and Borrower agrees that Lender, and Borrower agrees that Lender
shall be entitled to temporary and permanent injunctive relief in any such case
without the necessity of proving actual damages.

     Section 11.5. Remedies Are Cumulative No remedy set forth herein is
exclusive of any other available remedy or remedies, but each is cumulative and
in addition to every other right or remedy given under this Agreement or under
any other agreement between Lender and Borrower or now or hereafter existing at
law or in equity or by statute. Lender may pursue its rights and remedies
concurrently or in any sequence, and no exercise of one right or remedy shall be
deemed to be an election. No delay by Lender shall constitute a waiver, election
or acquiescence by it.

                                   SECTION 12
                                   INDEMNITY

     Section 12.1. General Indemnity Borrower shall protect, indemnify and
defend and save harmless Lender and its directors, officers, agents and
employees from and against any and all loss, cost, liability (including
negligence, tort and strict liability), expense, damage, suits or demands
(including fees and disbursements of counsel) on



                                       17
<PAGE>

account of any suit or proceeding before any Governmental Authority which arises
from the transactions contemplated in this Agreement or otherwise arising in
connection with or relating to the Loan and any security therefor, unless such
suit, claim or damages are caused by the negligence or intentional malfeasance
of Lender or its directors, officer, agents or employees. Upon receiving
knowledge of any suit, claim or demand asserted by a third-party that Lender
believes is covered by this indemnity, Lender shall give Borrower timely notice
of the matter and an opportunity to defend it, at Borrower's sole cost and
expense, with legal counsel acceptable to Lender. Lender may, at its option,
also require Borrower to so defend the matter. This obligation on the part of
Borrower shall survive the termination of this Agreement and the repayment of
the Note.

                                  MISCELLANEOUS

     Section 13.1. Delay and Waiver No delay or omission to exercise any right
shall impair any such right or be a waiver thereof, but any such right may be
exercised from time to time and as often as may be deemed expedient. A waiver on
one occasion shall be limited to that particular occasion.

     Section 13.2. Complete Agreement This Agreement and the Schedules are the
complete agreement of the parties hereto and supersede all previous
understandings relating to the subject matter hereof. This Agreement may be
amended only by an instrument in writing that explicitly states that it amends
this Agreement and is signed by the party against whom enforcement of the
amendment is sought. This Agreement may be executed in counterparts, each of
which will be an original and all of which will constitute a single agreement.

     Section 13.3. Severability; Headings If any part of this Agreement or the
application thereof to any Person or circumstance is held invalid, the remainder
of this Agreement shall not be affected thereby. The section headings herein are
included for convenience only and shall not be deemed to be a part of this
Agreement.

     Section 13.4. Binding Effect This Agreement shall be binding upon and inure
to the benefit of the respective legal representatives, successors and assigns
of the parties hereto; however, Borrower may not assign any of its rights or
delegate any of its Obligations hereunder. Lender (and any subsequent assignee)
may transfer and assign this Agreement and deliver the Collateral to the
assignee, who shall thereupon have all of the rights of Lender; and Lender (or
such subsequent assignee who in turn assigns as aforesaid) shall then be
relieved and discharged of any responsibility or liability with respect to this
Agreement and said Collateral.

<PAGE>


place as Secured Party may from time to time designate by notice to Debtor. Any
other amounts required to be paid to Secured Party under this Agreement are due

then accrued Secured Obligations in such order as Secured Party may choose.

        (f) The Advances shall not be subject to prepayment or redemption in
whole or in part prior to the expiration of the Term set forth in the Schedule
executed in connection with said Advance.

     2.1 Grant of Security Interest. In consideration of the Advances to be made
by Secured Party to Debtor under this Agreement, and to secure the payment and
performance of the Secured Obligations, Debtor hereby grants and assigns to
Secured Party, its successors and assigns, a security interest in the Collateral
described in section 2.2 below.

     2.2 Collateral. To the extent covered in any Schedules executed pursuant to
this Agreement, Collateral includes

         (a) all personal property consisting of "equipment", and "proceeds" as
defined in the Pennsylvania Commercial Code and all furniture, fixtures,
machinery or other property, and

         (b) accounts receivable, contract rights, instruments, documents,
chattel paper and all other forms of obligations owing to Debtor arising out of

financed under this Agreement, whether or not earned by performance, and any and
all credit insurance, guaranties, and other security therefor, as well as any
books and records relating to the forgoing, whether now owned or hereafter
acquired, and all substitutions, renewals or replacements of and alterations,
additions or improvements, if any, to such Collateral, together with, in each
and every case, all proceeds thereof. Each item of Collateral shall secure not
only the specific Advances made by Secured Party to Debtor as set forth in any
Schedule, but also all other present and future indebtedness or obligations of
Debtor to Secured Party of every kind and nature whatsoever. Debtor warrants and
agrees that the Collateral will be used primarily for business or commercial
purposes and that regardless of the manner of affixation, the Collateral shall
remain personal property and shall not become part of the real estate. Debtor
agrees to keep the Collateral at the locations set forth in the Schedule(s)
covering said Collateral and will not make any change in the location of the
Collateral within such state, and will not remove the Collateral from such state
without the prior written consent of Secured Party.

     3. Time is of the Essence; Late Charges. Time is of the essence in this
Agreement and if any Monthly Loan Repayment is not paid within the ten (10) days
after the due date thereof, Secured Party shall have the right to add and
collect, and Debtor agrees to pay:

        (a) A late charge on and in addition to, such Monthly Loan Repayment
equal to five percent (5%) of such Monthly Loan Repayment or a lesser amount if
established by any State or Federal statute applicable thereto; and

        (b) Interest on such Monthly Loan Repayment from thirty (30) days after
the due date until paid at the rate of eighteen (18%) per annum.

     4. No Warranties. This Agreement is solely a financing agreement. Debtor
acknowledges that: The Collateral has or will have been selected and acquired
solely by Debtor for Debtor's purposes; Secured Party is not the manufacturer,
dealer, vendor or supplier of the Collateral; the Collateral is of a size,
design, capacity, description and manufacture selected by Debtor; Debtor is
satisfied that the Collateral is suitable and fit for its purposes; and SECURED
PARTY HAS NOT MADE AND DOES NOT MAKE ANY WARRANTY OR REPRESENTATION WHATSOEVER,
EITHER EXPRESS OR IMPLIED, AS TO THE FITNESS, CONDITION, MERCHANTABILITY, DESIGN
OR OPERATION OF THE COLLATERAL, ITS FITNESS FOR ANY PARTICULAR PURPOSE, THE
VALUE OF THE COLLATERAL, THE QUALITY OR CAPACITY OF THE MATERIALS IN THE
COLLATERAL OR WORKMANSHIP IN THE COLLATERAL, NOR ANY OTHER REPRESENTATION OR
WARRANTY WHATSOEVER.

     4.1 No Agency. Debtor acknowledges and agrees that none of the
manufacturer, vendor, dealer or supplier, nor any salesman, representative, or
other agent of the manufacturer, dealer, vendor or supplier, is an agent of
Secured Party. No salesman, representative or agent of the manufacturer, dealer
vendor or supplier is authorized to waive or alter any term or condition of this
Agreement, and no representation as to the Collateral or any other matter by any
manufacturer, dealer, vendor or supplier shall in any way affect Debtor's duty
to pay the Monthly Loan Repayment and perform his other obligations as set forth
in this Agreement.

<PAGE>

     5. Acceptance. Execution by Debtor and Secured Party of the Schedule
covering the Collateral will conclusively establish that such Collateral has
been included under and will be subject to all of the terms and conditions of
this Agreement. If Debtor has not furnished Secured Party with an executed
Schedule by the earlier of fourteen (14) days after receipt thereof or
expiration of the commitment set forth in any applicable Equipment Financing
Commitment, Secured Party may terminate its obligation to make any Advances with
respect to any applicable Collateral.

     6. Insurance and Risk of Loss. All risk of loss of, damage to, or
destruction of the Collateral shall at all times be borne by Debtor. Debtor will
procure forthwith and maintain property and general liability insurance with
extended or combined additional coverage on the Collateral for the full
insurable value thereof for the life of this Agreement and any Schedule(s) plus
such other insurance as Secured Party may specify, and promptly deliver each
policy to Secured Party with a standard long form endorsement attached showing
Secured Party or assigns as additional insureds and loss payees. Each insurer

        (a) Debtor is duly organized and existing under the laws of the State of
its formation without limit as to the duration of its existence, and is
authorized and in good standing to do business in said State; Debtor has
corporate powers and adequate authority, rights and franchises to own its own
property and to carry on its business as now conducted, and is duly qualified
and in good standing in each state in which the character of the properties

necessary; and Debtor has the corporate power and adequate authority to make and
carry out this Agreement.

Provision of its articles of formation or bylaws, and this Agreement is a valid
and binding obligation of Debtor legally enforceable in accordance with its
terms.

        (c) The execution, delivery and performance of this Agreement will not
contravene or conflict with any agreement, indenture or undertaking to which
Debtor is a party or by which it or any of its property may be bound by or
affected, and will not cause any lien, charge or other encumbrance to be created
or imposed upon any such property by reason thereof.

        (d) There is no material litigation or other proceeding pending or
threatened against or affecting Debtor, and it is not in default with respect to
any order, writ, injunction, decree or demand of any court or other govemmental
or regulatory authority. The balance sheets of Debtor and the related profit and
loss statements and other financial data as submitted in writing by Debtor to
Secured Party in connection with this Agreement, are true and correct, and said
balance sheets and profit and loss statements truly represent the financial
condition of Debtor as of the dates thereof.

        (e) Debtor has good and valid title to the Collateral which is free from
and will be kept free from all liens, claims, security interests and
encumbrances, except for the security interest granted hereby.

        (f) No financing statement covering the Collateral or any proceeds
thereof is on file in favor of anyone other than Secured Party, but if such
other financing statement is on file, it will be terminated or subordinated.

        (g) All necessary action, including the filing of UCC-1 Financing
Statements, has or will be made to give Secured Party a first priority security
interest in the Collateral. Debtor agrees to permit Secured Party to pre-file

(hereinafter collectively referred to as "CLI" or the "Corporation")).

WHEREAS CLI wishes to protect, indemnify and hold harmless members of its Board
of Directors and corporate officers;

WHEREAS TWC is an officer and director of CLI, and requires such corporate
protection and indemnification in order to serve the needs of CLI;

NOW THEREFORE the parties hereto agree as follows:

1. Standard of Care and Justifiable Reliance - TWC shall stand in a fiduciary
relation to the Corporation and shall perform his or her duties, as a director,
including, duties as a member of any committee of the board upon which the
director serve, in good faith, in a manner TWC reasonably believes to be in the
best interests of the corporation and with such care, including reasonable
inquiry, skill and diligence, as a person of ordinary prudence would use under
similar circumstances. In performing his or her duties, TWC shall be entitled to
rely in good faith on information, opinions, reports or statements, including
financial statements and other financial data, in each case prepared or
presented any of the following:

          a. One or more officers or employees of the corporation whom TWC
     reasonably believes to be reliable and competent in the matters presented.

          b. Counsel, public accountants or other persons as to matters which

     of such person.

          c. A committee of the board upon which TWC does not serve, duly
     designated in accordance with law, as to matters within its designated
     authority, which committee TWC reasonably believes to merit confidence.

TWC shall not be considered to be acting in good faith if he has knowledge
concerning the matter in question that would cause his or her reliance to be
unwarranted.

2. Consideration of Factors

In discharging, the duties of his positions, TWC may, in considering the best
interests of the Corporation, consider the effects of any action upon employees,
upon suppliers and customers of the Corporation and upon communities in which
offices or other establishments of the corporation are located, and all other
pertinent factors. The consideration of those factors shall not constitute a
violation of Section 1 of this Agreement.

3. Presumption.

taken as a director or any failure to take any action shall be presumed to be in
the best interests of the corporation.

Re: Restricted Stock Award
    Mr. James J. Wiley

Dear Jim:

     It gives me pleasure on behalf of the Board of Directors of Cardiovascular
Laboratories, Inc. to inform you that the Board of Directors of Cardiovascular
Laboratories, Inc. (the "Company") have granted you (the "Optionee") a
Restricted Stock Award, (the "Option") on the 5th day of August, 1998 (the
"Grant Date") to purchase shares of the Company's Common Stock. Your performance
has helped strengthen the Company and this award represents the Company's
recognition of this as well as your potential for making significant
contributions in the years ahead. This Option provides you, as one of our key
employees, with added incentive to pursue the profitable growth of the Company.

     The terms and conditions of your Option are as set forth below.

     1. Grant. The Company hereby grants to the Optionee an Option to purchase
on the terms and conditions hereinafter set forth all or any part of any
aggregate of 100,000 shares of the Company's Common Stock, without par value
(the "Option Shares") at the purchase price of $0.10 per share (the "Option
Price"). This Option is not intended to be an "Incentive stock option" within
the meaning of section 422(b) of the Internal Revenue Code of 1986 (the "Code").
This Option is granted pursuant to and is subject to the terms and provisions of
the Company's 1998 Stock Option Plan (Effective May 1, 1998) (the "Plan"). All
questions of interpretation of the Plan and this Option shall be determined by
the Board, which determinations shall be final, binding and conclusive.

     2. Term.

        (a) General Rule. The Option granted hereunder shall be exercisable in
three cumulative annual installments, with each installment first exercisable on
the exercise date in the chart below for the number of Option Shares set across
from such exercise date, provided the Optionee then is a common law employee,
retained contractor or director of the Company or one of its Affiliates (as
defined in the Plan). Further, this Option may become sooner exercisable to the
extent provided under subsection 2(b) below. The Option granted hereunder shall
terminate in full at 5:00 P.M. Philadelphia, Pennsylvania time on December 31,
2009, unless sooner terminated under subsection 2(d) or (e) below. Any
installment may be


<PAGE>


exercised in whole or in part, except that this Option may in no event be
exercised with respect to fractional shares.

          Exercise Date                                   Option Shares
          -------------                                   -------------
Date of Grant                                                50,000

One Year Following Date of Grant                             25,000

Two Years Following Date of Grant                            25,000

        (b) Special Rule for Death, Disability or Retirement. If the Optionee's
employment terminates due to death, disability, or retirement (as defined below)
prior to the date this Option is 100% exercisable, the installment which would
become exercisable on the next following exercise date shall become exercisable.
The Optionee's employment will be deemed to terminate due to "retirement" if, on
the Optionee's termination date, the Optionee is at least age 65 or the sum of
the Optionee's age and completed years of employment with the Company or its
subsidiaries (including employment with an entity acquired by the Company or a
subsidiary) measured from the Optionee's date of hire is at least 75. Except to
the limited extent provided in the preceding sentence, the portion of an Option
which is exercisable shall be fixed on the Optionee's employment termination
date.

        (c) Forfeiture. This Option shall terminate immediately upon a finding
by the Committee, after full consideration of the facts presented on behalf of
both the Company and the Optionee, that the Optionee has engaged in any sort of
disloyalty to the Company or any of its Affiliates, including, without
limitation, fraud, embezzlement, theft, commission of a felony or proven
dishonesty in the course of the Optionee's employment or has disclosed trade
secrets or confidential information of the Company or an Affiliate. In such
event, in addition to immediate termination of the Option, the Optionee, upon a
determination by the Committee, shall automatically forfeit all Option Shares
upon the Company's refund of the Option Price. Further, the Company may withhold
delivery of share certificates pending the resolution of any inquiry that could
lead to a finding resulting in a forfeiture. This Option shall also terminate
if, for any reason, the Participant ceases to be in the employ of the Company or
its Affiliates or ceases to be retained as a consultant for a period of one-year
from the date upon when this Option becomes first exercisable. In such event, in
addition to termination of the Option, if the Participant has acquired Option
Shares during a period of less than one-year from the date upon when each Option
installment set forth in Section 2(a) becomes first exercisable, the Participant
shall automatically forfeit all such Option Shares upon the Company's refund of
the Option Price.

     3. Method of Option Exercise.

        (a) Notice. When exercisable under Section 2, the Optionee may exercise
this Option by a written notice of such exercise to the Company's Secretary
pursuant to Section 8 and of payment in full of the Option Price for the Option
Shares to be purchased. Each such notice shall specify the number of Option
Shares to be purchased.

        (b) Medium of Payment. The Optionee shall pay for the Option Shares
(i) in cash, (ii) by certified check payable to the order of the Company,
(iii) in shares of the Company's Common Stock which the Optionee held for at
least six months as of the


<PAGE>


exercise date, (iv) by a combination of the foregoing, (v) by delivery to the
Company of a properly executed notice of exercise together with irrevocable
instructions to a broker to deliver to the Company promptly the amount of the
proceeds of the sale of all or a portion of the Option Shares or of a loan from
the broker to the Optionee necessary to pay the aggregate exercise price
payable for the purchased Option Shares plus all applicable federal, state and
local taxes required to be withheld by the Company by reason of such exercise or
(vi) by such other mode of payment as the Committee may approve. If payment is
made in whole or in part in shares of the Company's Common Stock, then the
Optionee shall deliver to the Company certificates registered in the Optionee's
name representing shares of the Company's Common Stock owned by such Optionee,
free of all liens, claims and encumbrances of every kind and having a fair
market value on the date of delivery that is not greater than the Option Price
of the Option Shares with respect to which such Option is to be exercised,
accompanied by stock powers duly endorsed in blank by the Optionee.
Notwithstanding the foregoing, the Committee may impose such limitations and
prohibitions on the use of shares of the Company's Common Stock to exercise an
Option as it deems appropriate.

        (c) Securities Laws. Each notice of exercise shall (unless the Option
Shares are covered by a then current registration statement under the Securities
Act of 1933, as amended (the "Act")), contain the Optionee's acknowledgment in
form and substance satisfactory to the Company that (i) such Option Shares are
being purchased for investment and not for distribution or resale (other than a
distribution or resale which, in the opinion of counsel satisfactory to the
Company, may be made without violating the registration provisions of the Act),
(ii) the Optionee has been advised and understands that (A) the Option Shares
may not be registered under the Act and may be "restricted securities" within
the meaning of Rule 144 under the Act and may be subject to restrictions on
transfer and (B) the Company is under no obligation to register the Option
Shares under the Actor to take an action which would make available to the
Optionee any exemption from such registration, and (iii) such Option Shares may
not be transferred without compliance with all applicable federal and state
securities laws. Notwithstanding the foregoing, should the Company be advised by
counsel that issuance of Option Shares should be delayed pending (iv)
registration under federal or state securities laws or (v) the receipt of an
opinion that an appropriate exemption therefrom is available, the Company may
defer exercise of this Option until either such event in (iv) or (v) has
occurred.

        (d) Transfer to Comply with the securities Act of 1933. This Option may
not be exercised and neither this Option nor any of the Option Shares, nor any
interest in either, may be sold, assigned, pledged, hypothecated, encumbered or
in any other manner transferred or disposed of, in whole or in part, except in
compliance with applicable United States federal and state securities laws and
the terms and conditions hereof. Each Option shall bear a legend in
substantially the same form as the legend set forth on the first page of this
Option. Each certificate for Option Shares issued upon exercise of this Option,
unless at the time of exercise such Option Shares are acquired pursuant to a
registration statement that has been declared effective under the Act, shall

AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO AN EFFECTIVE REGISTRATION
STATEMENT OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE
AN OPINION OF LEGAL COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER


<PAGE>

AND ANY APPLICABLE STATE SECURITIES LAWS.

substitution for any certificate for any Option Shares bearing such legend
(except a new certificate for any Option Shares issued after the acquisition of
such Option Shares pursuant to a registration statement that has been declared
effective under the Act) shall also bear such legend unless, in the opinion of
legal counsel for the Company, the Option Shares represented thereby need no
longer be subject to the restriction contained herein. The provisions of this
Section 3(d) shall be binding upon all subsequent holders of certificates for
Option Shares bearing the above legend and all subsequent holders of this
Option, if any.

        (e) Brokerage Account. Each notice of exercise may instruct the Company,
in such form as the Board shall prescribe, to deliver Option Shares upon Option
exercise to any registered broker or dealer which the Company approves in lieu
of delivery to the Optionee.

     4. Transfers. During the Optionee's lifetime, the Optionee may transfer
this Option to a spouse or a lineal ascendant or descendant or a trust for the
benefit of such a person or persons or a partnership in which such persons are
the only partners, provided the Optionee receives no consideration for any such
transfer. At the Optionee's death, the Optionee may transfer this Option by will
or by the laws of descent and distribution. If a transfer occurs under this
Section, the transferred Option shall remain subject to all Plan provisions. A

to the Optionee's consent.

     7. Withholding of Taxes.

        (a) General Rule. The Company may deduct from salary, fees or other
amounts payable to the Optionee any amount necessary to satisfy any federal,
state and/or local withholding tax requirements unless the Optionee pays over to
the Company an amount sufficient to satisfy such liability.

        (b) Payment in Shares. The Optionee may elect that the Company satisfy
any applicable minimum withholding tax requirement by retaining a Option Shares
the Company would otherwise transfer to the Optionee upon exercise of the Option
which have a fair market value equal to such withholding requirement.
Notwithstanding the foregoing, the Committee may impose such limitations and
prohibitions on the use of Option Shares to satisfy withholding tax requirements
as it deems appropriate.

     8. Notices. Any notice to be given to the Company shall be addressed to the
Secretary of the Company at its principal executive office, and any notice to be
given to the Optionee shall be addressed to the Optionee at the address then
appearing for the Optionee on the Company's records, or at such other address as

          Exhibit A to April 15, 1998 Consent of Majority Shareholder

adopts the 1998 CLI Stock Option Plan effective April 17, 1998 (the "Plan") as
an additional incentive to eligible employees and eligible independent
contractors (as determined under Section 3) to enter into or remain in the
employ or service of the Company or any Affiliate (as defined below) and to
devote themselves to the Company's success by providing them with an opportunity
to acquire or increase their proprietary interest in the Company through receipt
of (a) rights (the "Options") to purchase the Company's Common Stock (the
"Common Stock") or (b) Common Stock subject to conditions of forfeiture (the
"Restricted Stock Awards"). Each Option granted under the Plan shall specify
whether or not it is intended to be an incentive stock option ("ISO") within the
meaning of section 422(b) of the Internal Revenue Code of 1986, as amended (the
"Code") or a non statutory stock option ("NSO") for federal income tax purposes.
For purposes of the Plan, the term "Affiliate" shall mean a corporation which is
a parent corporation or a subsidiary corporation with respect to the Company
within the meaning of section 424(e) or (f) of the Code.

     2. Administration.

          (a) Committee. The Plan shall be administered by the Board of
     Directors (the "Board") or a committee designated by the Company's Board
     (the "Committee").

          (b) Meetings. The Board or the Committee shall hold meetings at such
     times and places as it may determine. Acts approved at a meeting by a
     majority of the members of the Board or the Committee present at a meeting
     at which there is a quorum or acts approved in writing by the unanimous
     consent of the Board or the Committee shall be the valid acts of the Board
     or Committee.

          (c) Grants. The Board or Committee shall from time to time at its
     discretion direct the Company to grant Options or Restricted Stock Awards
     pursuant to the terms of Plan. Subject to the express provisions of the
     Plan, the Board or Committee shall have plenary authority to determine the
     persons to whom and the times at which Options or Restricted Stock Awards
     shall be granted, the number of shares of Common Stock to be granted under
     an Option or Restricted Stock Award and the price and other terms and
     conditions thereof, including a specification with respect to whether or
     not an Option is intended to be an ISO. In making such determinations the
     Board or Committee may take into account the nature of the person's
     services and responsibilities, the person's present and potential
     contribution to the Company's success and such other factors as it may deem
     relevant. The Board's or Committee's interpretation of any provision of the

                                       1

     be final, binding and conclusive.

          (d) Exculpation. Each Board or Committee member shall be acting in the
     capacity of a director of the Company for the purpose of Articles VI and
     VII of the Company's Articles of Incorporation in connection with the
     administration of the Plan or the granting of Options or Restricted Stock
     Awards under the Plan.

          (e) Indemnification. Each Board or Committee member shall be entitled
     to indemnification by the Company in accordance with the provisions and
     limitations of Article VII of the Company's Bylaws, as the same may be
     amended from time to time, in connection with or arising out of any action,
     suit or proceeding with respect to the administration of the Plan or the
     granting of Options or Restricted Stock Awards under the Plan in which he
     may be involved by reason of his being or having been a Board or Committee
     member, whether or not he continues to be a Board or Committee member at
     the time of the action, suit or proceeding.

     3. Eligibility. All persons the Company or its Affiliates employ as
employees or retained as independent contractors or directors of the Company
who, in the Committee's judgment, hold positions of responsibility or whose
performance can have a significant or material effect on the Company's long-term
success or achievement of specific objectives shall be eligible to participate

determine whether an individual qualifies as a Participant. Subject to the
Plan's terms and restrictions, a Participant may receive more than one Option or
Restricted Stock Award; provided, however, a Participant may not receive Options
and Restricted Stock Awards in any one calendar year for more than an aggregate

nonemployee member of the Company's Board of Directors may not receive an Option
which is intended to be an ISO.

Stock for which the Committee may issue Options or Restricted Stock Awards under
the Plan is 1,750,000 shares, adjusted as provided in Section 9 (the "Plan

Common Stock or Common Stock held in or hereafter acquired for the Company's
treasury. If any outstanding Option or Restricted Stock Award granted under the
Plan expires, lapses or is terminated for any reason, the Plan Shares allocable
to the unexercised portion of such Option or forfeited portion of such
Restricted Stock Award may again be the subject of grant pursuant to the Plan.

     5. Term of Plan. The Plan is effective as of April 17, 1998, the date on
which it was adopted by the Company's Board of Directors. No Option or
Restricted Stock Award granted under the Plan shall be exercisable or
nonforfeitable unless the Plan is approved by vote of a majority of outstanding
voting stock of the Company on or before December 31, 1999. No Option or
Restricted Stock Award may be granted under the Plan after December 31, 2008.

     6. Terms and Conditions of Options. Options granted pursuant to the Plan
shall be evidenced by written documents (the "Option Documents") in such form or
forms as the Committee shall from time to time approve. Option Documents shall
comply with and be subject to the terms and conditions set forth below and such
other terms and conditions which the Committee shall from time to time specify
with respect to a particular Option or Options provided they are not
inconsistent with the terms of the Plan. The applicable terms need not be
uniform between or among Options.

          (a) Number of Shares. Each Option Document shall state the number of
     Shares to which it pertains.

          (b) Option Price. Each Option Document shall state the price at which
     Shares under Option may be purchased (the "Option Price"). It is expressly
     intended that the Option Price may be less than the fair market value of
     the Common Stock on the date the option is granted, except that the Option
     Price with respect to ISOs shall not be less than 100% of the fair market
     value of the Common Stock on the date of grant; provided, however, if an
     ISO is granted to a Participant who then owns, directly or by attribution
     under section 424(d) of the Code, shares possessing more than ten percent
     of the total combined voting power of all classes of stock of the Company
     or an Affiliate, then the Option Price for such ISO shall be at least 110%
     of the Common Stock's closing price on the date the Option is granted.

          (c) Exercisablity.

               (i) Options shall be exercisable at such time or times and
          subject to such terms and conditions as shall be determined by the
          Board or Committee at or after grant. If the Board or Committee
          provides in its discretion, that any Option is exercisable only in
          installments, the Board or Committee may waive such installment
          exercise provisions at any time at or after grant in whole or in part,
          based on such factors as the Board or Committee shall determine, in
          its sole discretion.

               (ii) Change in Control. A "Change in Control" for purposes of
          this Plan shall mean any one of the following events:

                    (A) at any time during a period of two (2) consecutive
               years, at least a majority of the Board shall not consist of
               Continuing Directors. "Continuing Directors" shall mean directors
               of the Company at the beginning of such two-year period and
               directors who subsequently became such and whose selection or
               nomination for election by the Company's shareholders was
               approved by a majority of the ten Continuing Directors; or

                    (B) any person or "group" (as determined for purposes of
               Regulation 13D-G promulgated by the Commission under the Exchange
               Act or under any successor regulation), but excluding any
               majority-owned subsidiary or any employee benefit plan sponsored
               by the Company or any subsidiary or any trust or investment
               manager for the account of such a plan, shall have acquired
               "beneficial ownership" (as determined for purposes of such
               regulation) of the Company's securities representing fifty

                                       3
<PAGE>

               percent (50%) or more of the combined voting power of the
               Company's then outstanding securities unless such acquisition is
               approved in advance by a majority of the directors of the Company
               who were in office immediately preceding such acquisition and any
               individual selected to fill any vacancy created by reason of the
               death or disability of any such director; or

                    (C) the Company becomes a party to a merger, consolidation
               or share exchange in which either (i) the Company will not be the
               surviving corporation or (ii) the Company will be the surviving
               corporation and any outstanding shares of Common Stock will be
               converted into shares of any other company (other than a
               reincorporation or the establishment of a holding company
               involving no change in ownership of the Company or other
               securities or cash or other property (excluding payments made
               solely for fractional shares); or

                    (D) the Company's shareholders (i) approve any plan or
               proposal for the disposition or other transfer of all, or
               substantially all, of the assets of the Company, whether by means
               of a merger, reorganization, liquidation or dissolution or
               otherwise or (ii) dispose of, or become obligated to dispose of,
               50% or more of the outstanding capital stock of the Company by
               tender offer or otherwise. If a Change in Control has occurred,
               all outstanding, and fully vested options granted under the Plan
               shall be immediately exercisable by the holder of the option for
               the total remaining number of Shares covered by the option and
               shall survive any such event.

          (d) Medium of Payment. A Participant shall pay for Shares under Option
     (i) in cash, (ii) by certified check payable to the order of the Company,
     (iii) in shares of the Common Stock held by the Participant for a least six
     months as of the exercise date, (iv) by a combination of the foregoing, (v)
     by delivery to the Company of a properly executed notice of exercise
     together with irrevocable instructions to a broker to deliver to the
     Company promptly the amount of the proceeds of the sale of all or a portion
     of the Shares or of a loan from the broker to the Participant necessary to
     pay the aggregate exercise price payable for the purchased Shares plus all
     applicable federal, state and local income and employment taxes required to
     be withheld by the Company by reason of such exercise or (vi) by such other
     mode of payment as the Board or Committee may approve. If payment is made
     in whole or in part in shares of the Common Stock, then the Participant
     shall deliver to the Company certificates registered in the name of such
     Participant representing shares of Common Stock owned by such Participant,
     free of all liens, claims and encumbrances of every kind and having a fair
     market value on the date of delivery that is not greater than the Option
     Price of the Shares with respect to which such Option is to be exercised,
     accompanied by stock powers duly endorsed in blank by the Participant.
     Notwithstanding the foregoing, the Committee may impose such limitations
     and prohibitions on the use of shares of the Common Stock to exercise an
     Option as it deems appropriate.

          (e) Termination of ISOs. Unless the Board or Committee provides
     otherwise in an Option Document, no unvested ISO may be exercised until
     vested and a fully vested ISO shall not be exercisable after the first to
     occur of the following:

                                       4
<PAGE>


               (i) Term Capitation. Expiration of the term specified in the
          Option Document, which shall not exceed ten years from the date of
          grant or five years from the date of grant if the Participant on the
          date of grant owns, directly or by attribution under section 424(d) of
          the Code, shares possessing more than ten percent of the total
          combined voting power of all classes of stock of the Company or of an
          Affiliate,

               (ii) Employment Termination. Expiration of 10 days from the date
          the Participant's employment with the Company or its Affiliates
          terminates unless any of subsection 6(c)(iii) - 6(c)(vi) applies:

               (iii) Retirement. Expiration of 30 days from the date the
          Participant's employment with the Company or its Affiliates terminates
          due to "retirement";

               (iv) Disability. Expiration of six-months from the date the
          Participant's employment with the Company or its Affiliates terminates
          if the Participant terminates due to disability (within the meaning of
          section 22(e)(3) of the Code);

               (v) Death. Expiration of the Option term if the Participant's
          employment terminates due to death, or

               (vi) Forfeiture. The date on which forfeiture occurs under
          subsection 6(g).

          (f) Termination of NSO's. Unless the Committee provides otherwise in
     an Option Document, no unvested NSO may be exercised until vested and a
     fully vested NSO shall not be exercisable after the first to occur of the
     following:

               (i) Term Expiration. Expiration of the term specified in the
          Option Document, which shall not exceed ten years from the date of
          grant,

               (ii) Forfeiture. The date on which forfeiture occurs under
          subsection 6(g).

          (g) Forfeiture. An Option shall terminate immediately upon a finding
     by the Board or Committee, after full consideration of the facts presented
     on behalf of both the Company and the Participant, that the Participant has
     engaged in any sort of disloyalty to the Company or an Affiliate,
     including, without limitation, fraud, embezzlement, theft, commission of a
     felony or proven dishonesty in the course of his employment or service or
     has disclosed trade secrets or confidential information of the Company or
     an Affiliate or engaged in competition with the Company or an Affiliate. In
     such event, in addition to immediate termination of the Option, the
     Participant, upon a determination by the Board or Committee, shall
     automatically forfeit all Shares for which the Company has not yet
     delivered the share certificate upon the Company's refund of the Option
     Price.

                                       5
<PAGE>

          (h) Transfers. Generally, a Participant may not transfer any Option
     granted under the Plan, except that (i) during his lifetime, a Participant
     may transfer an NSO to a spouse or a lineal ascendant or descendant or a
     trust for the benefit of such person or persons or a partnership in which
     such persons are the only partners, provided the Participant receives no
     consideration for any such transfer and (ii) at the Participant's death, a
     Participant may transfer an Option by will or by the laws of descent and
     distribution. If a transfer occurs under this subsection, the transferred
     Option shall remain subject to all Plan provisions. A transferee shall be
     required to furnish proof satisfactory to the Committee of the transfer to
     him by gift or by will or laws of descent and distribution.

          (i) Limits on ISOs. Each ISO shall provide that to the extent the
     aggregate fair market value of Plan Shares with respect to which a
     Participant may exercise an ISO for the first time during any calendar year
     under any Company plan exceeds $100,000, then such Option shall be treated
     as an NSO rather than as an ISO.

          (j) Other Provisions. The Option Documents shall contain such other
     provisions including, without limitation, additional restrictions upon the
     exercise of the Option or additional limitations upon the term of the
     Option, as the Board or Committee shall deem advisable.

          (k) Amendment. The Board or Committee shall have the right to amend
     Option Documents issued to a Participant subject to the Participant's
     consent.

     7. Method of Option Exercise.

          (a) Notice. No Option shall be deemed to have been exercised prior to
     the Company's receipt of written notice of such exercise and of payment in
     fall of the Option Price for the Shares to be purchased. Each such notice
     shall specify the number of Shares to be purchased.

          (b) Securities Laws. Each notice of exercise shall (unless the Shares
     are covered by a then current registration statement under the Securities
     Act of 1933, as amended (the "Act")), contain the Participant's
     acknowledgment in form and substance satisfactory to the Company that (i)
     such Option Shares are being purchased for investment and not for
     distribution or resale (other than a distribution or resale which, in the
     opinion of counsel satisfactory to the Company, may be made without
     violating the registration provisions of the Act), (ii) the Participant has
     been advised and understands that (A) the Option Shares may not be
     registered under the Act and may be "restricted securities" within the
     meaning of Rule 144 under the Act and may be subject to restrictions on
     transfer and (B) the Company is under no obligation to register the Option
     Shares under the Act or to take any action which would make available to
     the Participant any exemption from such applicable federal and state
     securities laws. Notwithstanding the foregoing should the Company be
     advised by counsel that issuance of Shares should be delayed pending (iv)
     registration under federal or state securities laws or (v) the receipt of
     an opinion that an appropriate exemption therefrom is available, the
     Company may defer

                                       6
<PAGE>


     exercise of any Option granted hereunder until either such event in (iv) or
     (v) has occurred.

          (c) Brokerage Account. Each notice of exercise may instruct the
     Company, in such form as the Board or Committee shall prescribe, to deliver
     Shares upon Option exercise to any registered broker or dealer which the
     Company approves in lieu of delivery to the Participant.

          (d) Legend. Any certificate issued in respect of an Option shall be
     registered in the Participant's name and shall bear an appropriate legend
     referring to the terms, conditions and restrictions applicable under the
     Plan and Option Documents to the covered Shares.

     8. Terms and Conditions of Restricted Stock Awards. Restricted Stock Awards
made pursuant to the Plan shall be evidenced by written documents (the "award
Documents") in such form or forms as the Board or Committee shall from time to
time approve.

          (a) Number of Shares. Subject to Section 4, each Award Document shall
     state the number of Shares to which it pertains.

          (b) Restrictions and Limitations. Each grant shall be subject to such
     restrictions as the Board or Committee may impose. The applicable
     restrictions may lapse separately or in combination at such time or times,
     or in such installments, as the Board or Committee may deem appropriate. In
     addition, the Board or Committee may impose limits on the Participant's
     right to vote Shares or receive dividends or distributions on Shares under
     a Restricted Stock Award until such Shares become nonforfeitable. Each
     Award Document shall provide that the Participant has engaged in conduct
     which violates subsection 6(g) and that all forfeitable Shares shall become
     nonforfeitable upon the occurrence of a Chance in Control (as defined in
     subsection 6(c)(ii)).

          (c) Legend. Any certificate issued in respect of a Restricted Stock
     Award shall be registered in the Participant's name and shall bear an
     appropriate legend referring to the terms, conditions and restrictions
     applicable under the Plan and Award Document to the covered Shares. In
     addition, until such time as all restrictions applicable to the Shares
     lapse, the Board or Committee may provide for the certificate to be held in
     escrow by an escrow agent which the Board or Committee selects and the
     Company compensates.

          (d) Forfeiture.

               (i) General Rule. If a Participant terminates employment during
          any restriction period under circumstances which result in a
          forfeiture of Shares covered by the Restricted Stock Award or any
          event occurs or fails to occur which results in a forfeiture, the
          restricted Shares shall revert to the Company. Notwithstanding the
          foregoing, the Board or Committee may waive any restriction applicable
          to any Restricted Stock Award whenever the Board or Committee
          determines that such waiver is in the

                                       7
<PAGE>

          Company's best interests. Unless otherwise set forth in the
          Restricted Stock Award grant, an Option shall terminate if, for any
          reason, the Participant ceases to be in the employ of the Company or
          its Affiliates or ceases to be retained as a consultant for a period
          of one-year as determined from the date upon when the Option becomes
          first exercisable. In such event, in addition to termination of the
          Option, if the Participant has acquired Option Shares during a period
          of less than one-year from the date upon when each Option installment
          set forth in The Restricted Stock Award document becomes first
          exercisable, the Participant shall automatically forfeit all such
          Option Shares upon the Company's refund of the Option Price.

               (ii) Forfeiture for Cause. A Participant shall forfeit all
          forfeitable Shares covered by a Restricted Stock Award immediately
          upon a finding by the Board or Committee, after full consideration of
          the facts presented on behalf of both the Company and the Participant,
          that the Participants has engaged in any sort of disloyalty to the
          Company or an Affiliate, including, without limitation, fraud,
          embezzlement, theft, commission of a felony or proven dishonesty in
          the course of his employment or service or has disclosed trade secrets
          or confidential information of the Company or an Affiliate or engaged
          in competition with the Company or an Affiliate.

          (e) Transfers. Generally, a Participant may not transfer, assign,
     alienate, sell, encumber, or pledge Shares under a Restricted Stock Award
     until they are nonforfeitable and any purported transfer, assignment,
     alienation, sale, encumbrance or pledge shall be void and unenforceable.
     Notwithstanding the foregoing, (i) a Participant may transfer forfeitable
     Shares under a Restricted Stock Award to a spouse or a lineal ascendant or
     descendant or a trust for the benefit of such a person or persons or a
     partnership in which such persons are the only partners, provided the
     Participant receives no consideration for any such transfer and (ii) at the
     Participant's death, a Participant may transfer forfeitable Shares under a
     Restricted Stock Award by will or by the laws of descent and distribution.
     If a permitted transfer occurs under this subsection, the transferred
     Shares shall remain subject to all Plan provisions and all applicable
     conditions and restrictions under the Award Document. A transferee shall
     be required to furnish proof satisfactory to the Board or Committee of the
     transfer to him by gift or by will or laws of descent and distribution.

          (f) Securities Laws. Upon the advice of counsel, the Board or
     Committee may require a Participant to take or defer any action with
     respect to Shares covered under a Restricted Stock Award which counsel
     determines is necessary to comply with federal or state securities laws.

     9. Adjustments on Changes in Common Stock. The aggregate number of shares
and class of shares as to which Options or Restricted Stock Awards may be
granted hereunder, the number of Shares covered by each outstanding Option and
the Option Price thereof and each Restricted Stock Award shall be appropriately
adjusted in the event of a stock dividend, stock split, recapitalization or
other change in the number or class of issued and outstanding equity securities
of the Company resulting from a subdivision or consolidation of the Common Stock
and/or other outstanding equity security or recapitalization or other capital
adjustment (not including the issuance of Common Stock

                                       8
<PAGE>


upon the conversation of other securities of the Company which are convertible
into Common Stock) affecting the Common Stock which is effected without receipt
of consideration by the Company. The Board or Committee shall have authority to
determine the adjustments to be made under this Section and any such
determination by the Board or Committee shall be final, binding and conclusive;
provided, however, that no adjustment shall be made which causes an ISO to lose
its status as such without the consent of the Participant.

     10. Amendment of the Plan. The Board of Directors of the Company may amend
the Plan from time to time in such manner as it may deem advisable to terminate
the Plan in full. Nevertheless, the Board of Directors of the Company may not,
without obtaining approval by vote of a majority of the outstanding voting stock
of the Company within twelve months before or after such action, change the
class of individuals eligible to receive grants under the Plan or increase the
maximum number of shares of Common Stock as to which Options or Restricted Stock
Awards may be granted, except as provided in Section 9 hereof

     11. Continued Employment. The grant of an Option or a Restricted Stock
Award pursuant to the Plan shall not be construed to imply or to constitute
evidence of any agreement, express or implied, on the part of the Company or any
Affiliate to retain the Participant in the employ of the Company or an Affiliate
or as a member of the Company's or an Affiliate's Board of Directors or in any
other capacity.

     12. Withholding of Taxes.

          (a) General Rule. As a condition for the receipt of an Option or
     Restricted Stock Award, the Participant agrees that the Company (or the
     Affiliate employing him) may deduct from wages or other amounts payable to
     him or that he will pay over to the Company any amount necessary to satisfy
     any federal, state and/or local withholding tax requirements and that the
     Company shall have the right to take whatever action it deems necessary to
     protect its interests with respect to tax liabilities resulting from any
     act or event in connection with the Plan.

          (b) Payment in Shares. The Participant may elect that the Company
     satisfy any applicable minimum federal, state and/or local withholding tax
     requirement by retaining Shares the Company would otherwise transfer to him
     upon his exercise of an Option or satisfaction of all vesting conditions
     under a Restricted Stock Award which have a fair market value equal to such
     withholding requirement. Notwithstanding the foregoing, the Board or
     Committee may impose such limitations and prohibitions on the use of shares
     of the Common Stock to satisfy withholding tax requirements as it deems
     appropriate.

     13. Rules of Interpretation. Regardless of the number and gender
specifically used, words used in the Plan shall be deemed and construed to
include any other number (singular or plural) and any other gender (masculine,
feminine or neuter) as the context indicates is appropriate. Section headings
are for convenience only; they form no part of the Plan.

                                       9

     14. Substitution of Options in a Merger, Consolidation or Share Exchange.
In the event that the Company becomes a party to a merger, consolidation or
share exchange (a "Business Combination") and in connection therewith
substitutes Options under the Plan for options of another party to such Business
Combination, notwithstanding the provisions of the Plan, the terms of such
substituted options may have the same terms and conditions (provided that the
number of shares issuable and the exercise prices are adjusted in accordance
with the terms of the Business Combination) as the former options of such other
party to the Business Combination, provided, however, that the exercise price of
the Options to be granted under the Plan shall be lawful consideration as
determined by the Board or Committee.

     15. Notices and Communications. Should the Board of Directors deem it
appropriate or necessary to inform Plan Participants concerning any aspect of
the Plan, such notices and communications shall be sent to the Participant at
the address so noted in the Participant's Stock Option Grant or Restricted Stock
Award, as amended from time to time by sending written notice to the Company.
All such notices, advises and communications shall be deemed to have been
received (a) in the case of personal delivery or recognized overnight courier
service, on the date of such delivery and (1), in the case of mailing, on the
third business day following such mailing.

     16. Necessary Documents. If any Shareholder is required to sell his Shares
under the terms of this Agreement, such Shareholder or his legal representative
shall execute and deliver all necessary documents that reasonably may be
required to accomplish a complete transfer of such Shares.

     17. Specific Performance. In the event of a breach or threatened breach
under this Agreement, the parties agree that the remedy at law would be
inadequate and any party to this Agreement shall be entitled to appropriate
injunctive and other equitable relief including without limitation, specific
performance. Further, any non-breaching party shall be entitled to recover the
loss, cost and expense (including reasonable attorneys' fees) which such party
incurs in securing any relief at law or in equity.

     18. Modification. No waiver by any part hereto of any condition, or the
breach of any term or covenant contained in this Agreement, whether by conduct
or otherwise, in any one or more instances, shall be deemed or construed as a
further or continuing waiver of any such conditions or breach or waiver of any
other condition.

     19. Subsequent Signatories. As a condition to the transfer of any shares of
Common Stock, whether pursuant to an original issuance of shares of Common
Stock, a Permitted Transfer, or otherwise, the transferee of any of such shares

                                    AGREEMENT

This Agreement is made and entered into as of this 6th day of May, 1998 between
Brennan, Dyer & Company, LLC (the "Adviser") and Cardiovascular Laboratories,
Inc., a Nevada corporation, (the "Company").

In consideration of the mutual promises made herein, and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

     The Company hereby engages the Adviser on a non-exclusive basis for the
term specified in Paragraph 2 hereof to render consulting advice to the Company
as a financial and investment relations specialist relating to corporate and
similar matters upon the terms and conditions set forth herein. During the term
of this Agreement, the Adviser and the Company intend to evaluate the
possibilities for additional engagements that may be embodied in one or more
separate written agreements.

     Except as otherwise specified herein, this Agreement shall be effective
for twelve (12) months from the date hereof unless it is terminated by either
party upon one hundred twenty (120) days written notice received either by the
Adviser or the Company.

     During the term of this Agreement, the Adviser shall provide the Company
with such regular and customary consulting advice as is reasonably within the
scope of the advisory services contemplated by this Agreement. It is understood
and acknowledged by the parties that the value of the Adviser's advice is not
readily quantifiable, and that the Adviser shall be obligated to render advice
upon the request of the Company, in good faith and on a best efforts basis, but
shall not be obligated to spend any specific amount of time in so doing. The
Adviser's duties may include, but will not necessarily be limited to, providing
recommendations to the Company concerning the following matters:

          Assisting the Company in raising investment funds for the Company

          Rendering advice and assistance to the Company generally in connection
     with investment opportunities, including possible mergers and acquisitions.

          Assisting the Company in promotion of the Company

          Assisting the Company in financial public relations.

     In the event the Company shall complete an acquisition of an entity
presented to the Company by the Adviser, or the Company shall effect the sale of
its capital stock to a third person or entity introduced to the Company by the
Adviser, the Company shall pay the Adviser a fee based on the purchase price
(the "Purchase price") for such entity, or the purchase price for the Company's
capital stock, as the case may be, in accordance with the following formula:

          5% of the first $1 million of the Purchase Price
          (or portion thereof)

          4% of the 2nd $1 million of the Purchase Price
          (or portion thereof)

          3% of the 3rd $1 million of the Purchase Price
          (or portion thereof)


<PAGE>


          2% of the 4th $1 million of the Purchase Price
          (or portion thereof)

          1% of the balance of the Purchase price


For the purposes of this Agreement, "Purchase Price" shall mean the value on the
day of closing of stock, cash assets and all other property (real or personal)
paid, exchanged or received, directly by the Company.

     The Company recognizes and confirms that for advising the Company and in
fulfilling its engagement hereunder, the Adviser will use and rely on data,
material and other information furnished to the Adviser by the Company. The
Company acknowledges and agrees that in performing its services under this
engagement, the Adviser may rely upon the data, material and other information
supplied by the Company without independently verifying the accuracy,
completeness or veracity of same. Accordingly, the Company expressly agrees that
all data, material and other information furnished to the Adviser by the Company
shall not contain an untrue statement of material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstance under which they were made, not
misleading.

     The Adviser shall perform its services hereunder as an independent
contractor and not as an employee of the Company or an affiliate thereof. It is
understood and agreed to by the parties hereto that the adviser shall have no
authority to act for, represent or bind the Company or any affiliate thereof in
any manner except as may agreed to expressly by the Company in writing from time
to time.

     (a) This Agreement constitutes the entire Agreement and understanding of
the parties hereto, and supercedes any and all previous agreements and
understandings, whether oral or written, between the parties with respect to the
matters set forth herein.

     (b) All notices, requests, demands and other communications required or
permitted to be given hereunder shall be in writing and shall be deemed to have

                           Amendment (the "Amendment")
                                       to
                           Agreement Dated May 6, 1998
                                     between
                        Cardiovascular Laboratories, Inc
                                       and
                           Brennan Dyer & Company, LLC
                                (the "Agreement")



Whereas Cardiovascular Laboratories, Inc. ("CLI"), a Nevada corporation, wishes
to amend the Agreement to reflect CLI's intention to more fully engage and
compensate Brennan Dyer & Company, LLC (the "Advisor") in an effort to raise
equity financing for CLI and,

Whereas the Advisor wishes to amend the Agreement to reflect the Advisor's
intention to secure such financing for CLI and to further define the
compensation the Advisor shall receive for such financing efforts,

Now therefore, intending to be legally bound hereby, the parties agree to amend
the Agreement by replacing the original Section 4 of the Agreement in its
entirety with the following amended Section 4:

4.   The Advisor shall use its best efforts to complete an equity financing with
     net cash proceeds to CLI of not less than $600,000 nor more than $750,000
     (the "Equity Financing") as more fully described in this Section 4.

     a.   The Equity Financing shall be a transaction whereby CLI sells equity
          securities, or securities that contain an equity component to an
          investor or a group of investors (hereinafter referred to singularly
          as an :Investor" or collectively as "Investors"). While CLI would
          prefer to sell shares of its common stock to the Investor or
          Investors, CLI recognizes that the Equity Financing may consist of a
          sale of securities that may include, but is not limited to other
          securities or combination of securities that include a common stock
          equivalent component. Common stock equivalents include, without
          limitation, securities that convert into shares of common stock, are
          exchangeable for shares of common stock, or confer a right or
          privilege to an Investor or Investors to otherwise acquire shares of
          common stock.. An Equity Financing shall not be deemed to have taken
          place if it consists solely of the sale of debt securities without an
          common stock equity equivalent component.

     b.   Compensation for the Advisor's services shall consist of a fee of 10%
          of the gross amount of proceeds of any Equity Financing consummated by
          CLI during the term of the Agreement, regardless of whether such
          Investor was introduced by the Advisor or otherwise. This 10% fee
          shall be payable to the Advisor at the closing from the proceeds of
          the Equity Financing.

     c.   Additional compensation for the Advisor's services shall consist of a
          total of up to 250,000 shares of CLI unregistered common stock to be
          paid as follows:

          (i)  50,000 shares of CLI unregistered common stock to be issued upon
               execution of this Agreement,

          (ii) 200,000 shares of unregistered CLI common stock upon the closing
               of an Equity Financing at a per share common equivalent price
               equal to or greater than $0.25. ,

         (iii) If CLI, fails to accept the terms of a proposed Equity Financing
               (the "Proposed Equity Financing") with a per share common
               equivalent price equal to or greater than $0.25, and net proceeds
               to CLI equal to or greater than $600,000, then CLI


<PAGE>


               shall pay to the Advisor a rejection fee (the "Rejection Fee")
               equal to 200,000 shares of CLI's unregistered common stock
               provided, however, that the Proposed Equity Financing consists of
               a written offer directly from the Investor or Investors and is
               accompanied by written confirmation from the Advisor stating
               that, in the Advisor's professional opinion, the Proposed Equity
               Financing is being made by an Investor or Investors who have both
               the wherewithal and intention of proceeding to close an Equity
               Financing within 60 days of the date of the written offer of
               Proposed Equity Financing.

          (iv) All shares of common stock issued as compensation to the Advisor
               pursuant to the Agreement shall be subject to full piggyback
               registration rights subject to underwriter's limitation should
               such registration include an underwriter for the purposes of
               registration of shares for sale to public investors.

WHEREAS CLI entered into numerous leases with the predecessor and parent company
to ATLFS, known at various times as ATL Washington, Inc., ATL Ultrasound, Inc.,
and most recently as Advanced Technology Laboratories, Inc., (hereinafter
referred to as "ATL"), which leases are specifically identified in Exhibit I,
which is attached hereto and incorporated by this reference (hereinafter

WHEREAS CLI failed to make timely payments under the Leases and received a
notice of default pursuant to the terms of the Leases by ATLFS; and

WHEREAS CLI made certain allegations of business interference with existing
business of CLI by a certain business representative of ATL; and

WHEREAS ATLFS now services the Leases and has full legal responsibility for
resolving any and all of the issues relative to the Leases with CLI; and

WHEREAS CLI has returned certain equipment to ATLFS to which ATLFS has given
value and credited the outstanding balance of lease payments due from CLI with
such amount, and CLI has obtained additional separate financing; and

WHEREAS CLI and ATL, after lengthy negotiation, now wish to resolve any and all
disputes between them;

NOW THEREFORE, for and in consideration of the mutual promises and covenants
contained herein, and for good and valuable consideration, the receipt and
adequacy of which is acknowledged by each of the parties hereto, the parties
hereto agree as follows:

                                CLI'S OBLIGATIONS

     Payment. CLI agrees to pay ATLFS Four Hundred Thirty Eight Thousand Ninety
Seven and No/100 Dollars (438,097), by wire transfer to the account of ATLFS
pursuant to instructions to be provided by ATLFS prior to such transfer
immediately upon execution of this Agreement by CLI.

     Waiver and Release of Claims by CLI. With the exception of the obligations
set forth in this Agreement, CLI hereby waives and releases any and all claims,
causes of action and rights, whether known or unknown, contingent or
non-contingent, contractual or otherwise against ATLFS and ATL, or any of its
related, affiliated or subsidiary


<PAGE>


organizations and each of their respective directors, officers, agents,
representatives and employees, including, but not limited to, Robert L. Cedzo
("Releases") arising out of, or relating to the Leases, or any other matter. CLI
makes this commitment even though it understands that it may not, as of this
date, know all of these claims, and that it is relinquishing the right to pursue
any claims which it could have pursued before courts or administrative agencies
without having the opportunity to pursue those claims to a trial and have the
damages set by a judge and/or jury.

     Customer Service Provided by ATL. CLI agrees that issues concerning
customer service provided by ATL to CLI are, and will ultimately be subject to
the policies and decisions of ATL. CLI understands that ATLFS has not
participated and does not participate in the creation of such customer service
policies, and further, acknowledges that ATLFS cannot be responsible to CLI for
any decisions of ATL made concerning service issues, with respect to CLI.

                               ATLFS'S OBLIGATIONS

     Value of Returned Equipment. ATLFS acknowledges that CLI has returned
equipment to ATLFS and agrees that the value of such equipment shall be equal to
the outstanding balance of CLI on the Leases. As of the date of this Agreement,
ATLFS acknowledges that CLI has fulfilled its equipment return obligation with
respect to this Agreement.

     Satisfaction of Lease Payments. Upon execution of this Agreement by CLI,
ATLFS agrees to reduce all outstanding balances due ATLFS from CLI to zero and
thereafter the records of ATLFS shall reflect the satisfaction of all lease
payments due under the Leases from CLI to have been satisfied as of the date of
this Agreement.

     Equipment Retained by CLI. ATLFS agrees that upon receipt of the payment
from CLI under paragraph 1 of this Agreement, that CLI shall retain and have
free and clear title to the equipment specified on Exhibit II, attached hereto
and incorporated herein by this reference, including all attachments,
accessories, replacement parts, substitutions, additions, repairs and all
proceeds thereof currently and in the future, in the possession of CLI.

     Customer Service Provided by ATL. ATLFS acknowledges and is aware of ATL
customer service policies as they may apply to CLI, and it is ATLFS'
understanding and belief that upon payment in full of all outstanding balances
for past customer service provided by ATL to CLI, and only in that event, will
CLI become eligible for future customer service provided by ATL on a time and
materials basis. It is the further understanding and belief of ATLFS that such
eligibility of CLI to obtain ATL customer service is further conditioned upon
pre-paying for such services requested.

     Waiver and Release of Claims by ATLFS. With the exception of the
obligations set forth in this Agreement, ATLFS hereby waives and releases any
and all claims, causes of action and rights, whether known or unknown,
contingent or non-contingent, contractual or otherwise against CLI, or any of
its related, affiliated or subsidiary organizations and each of their respective
directors, officers, agents, representatives and employees, past and present,
and each of their successors and assigns ("Releases") arising out of, or


<PAGE>


relating to the Leases, or any other matter, with the exception of any matter,
services or business CLI may have had or has directly with ATL. ATLFS makes this
commitment even though it understands that it may not, as of this date, know all
of these claims, and that it is relinquishing the right to pursue any claims
which it could have pursued before courts or administrative agencies without
having the opportunity to pursue those claims to a trial and have the damages
set by a judge and/or jury.

                                  MISCELLANEOUS

     No Admission of Liability. This Settlement and Release Agreement shall not
be construed as an admission of liability by ATL of any liability, breach of any
agreement between ATL and CLI, or violation by ATL of any statute, law or
regulation.

     Governing Law and Venue. This Agreement shall be governed by the laws of
the State of Washington in effect as of the date of this Agreement. In any
dispute arising out of or related to this Agreement, the parties agree that
venue shall be had in King County, State of Washington.

     Enforcement. Interpretation and enforcement of this Agreement shall be
governed by the substantive and procedural laws that exist in the State of
Washington on the date of execution of this Agreement. In any action to enforce
any of the provisions of this Agreement, the prevailing party shall be entitled
to recover its reasonable attorney's fees and costs, in addition to any other
damages and remedies available at law or in equity.

IN WITNESS WHEREOF, the parties have entered into this Agreement as of the date
first set forth above.
