                                   The Company


We are a medical technology company that has developed and is testing Computed
Tomography Laser Mammography (CTLM(TM)) for detecting breast cancer through the
skin in a non-invasive procedure. The CTLM(TM) employs a laser and proprietary
scanning technology to produce visual images of the breast, which may be used to
detect and analyze tissue for indicia of malignancy or benignancy. The
components of the laser system are purchased from two unrelated parties and
assembled and installed into the CTLM(TM) by us. The CTLM(TM) will be used as an
adjunct to traditional breast imaging devices, such as mammography and
ultrasound machines, to assist in the detection of breast cancer. Medical
personnel will use the CTLM(TM) at medical facilities to do breast examinations
during routine check-ups and during more specific investigations in connection
with breast cancer.

Computed Tomography has had a basis in the science of medical imaging since the
early 1970's. Our chief executive officer Richard Grable, had experience with
Computed Tomography that inspired him to invent CT Laser Mammography in 1989.
The issues of evolving laser technology and software occupied the first several
years of our existence. After several limited clinical trials in our facilities
and the Strax Diagnostic Breast Clinic we learned what changes were required to
improve performance and stability of CTLM(TM). These changes included the
technological advances made with the lasers and other components. On July 8,
1999 we began a clinical investigational trial at Nassau County Medical Center,
East Meadow, NY. The clinical trials were then expanded to University of
Virginia Health System, Charlottesville, VA on November 15, 1999.


In connection with CTLM(TM) clinical trials, we are developing a clinical atlas
of the optical properties of benign and malignant tissues. The CTLM(TM) is
designed to provide the physician with objective visual data for interpretation
and further clinical analysis. Accordingly, we believe that the CTLM(TM) will
improve early diagnosis, reduce diagnostic uncertainty and decrease the number
of biopsies performed on benign breast lesions.

Due to the delays in obtaining the new laser system, the delays in the
modification and redesign of the CTLM(TM) and delays beyond our control
regarding hospital-based clinical trials, we are unable to determine when we
will receive FDA marketing clearance. In addition, due to these delays, we are
unable to determine when we will begin to generate revenue.

Our executive offices are located at 6531 NW 18th Court, Plantation, Florida
33313. Our telephone number is (954) 581-9800.

                               Recent Developments

On October 14, 1999, we exhibited our most recent clinical studies from our
ongoing clinical trials at Nassau County Medical Center at the 19th Annual
Breast Imaging Conference in Anaheim, CA. At this conference, our clinical
images were compared against those of x-ray mammograms.

In December 1999 at the 1999 Radiological Society of North America Meeting, we
presented for the first time for review to radiologists and other medical
professionals from around the world clinical images produced by the CTLM(TM). We
compared our images of various breast abnormalities acquired through our ongoing
clinical trials at Nassau County Medical Center with those images produced by
mammography equipment and ultrasound machines. We also demonstrated the
potential of fluorescence through a simulation with our CTLM(TM) device.

Furthermore, on November 29, 1999, we entered into a distribution agreement with
Cycle of Life Technologies, Inc., a division of INTRACOR Inc., an international
trading company of medical products based in Canada, which we believe will help
us generate up to $500,000 in revenues in the first quarter of 2000 and up to a
total of $12 million in revenues over the life of the agreement. This agreement
gives Cycle of Life the exclusive right to distribute and sell the CTLM(TM) in a
number of countries for a period of three years with the possibility of a
two-year extension of the exclusive distribution and sales rights if Cycle of
Life meets specific sales requirements. As of February 28, 2000, we have not
earned any revenues from this agreement. We are currently preparing the
necessary documents required for FDA export approval to allow us to sell the
CTLM(TM) in Canada.

In January 1997, we applied for a patent for a fluorescence imaging scanner. We
have received Issue Notification from the U.S. Department of Commerce, Patent
and Trademark Office indicating that the Patent for the fluorescence imaging
scanner was issued on September 14, 1999, as Patent No. 5,952,664. A fluorescent
marker is a chemical compound that allows light to be absorbed at specific
locations in the tissue, which assists in detection of cancerous tissues.

On February 1, 2000, we received a loan from Cycle of Life Technologies, Inc. in
the aggregate amount of $500,000 evidenced by a promissory note. The term of the
note is six months and the interest rate is 12% per annum.

We received notice from the U.S. Department of Commerce, Patent and Trademark
Office on February 8, 2000 that our patent application for our reconstruction
algorithm had been granted. This patent assigned to us protects the proprietary
algorithms that assists in the formation of the visual images of the CTLM(TM)
breast imaging device.

Our website has been updated with the latest White Paper on "The Potential of
Fluorescent markers in Medical Optical Imaging: Part Two." This "White Paper" is
a technical narrative written by our scientists and engineers which describes
the results of our experiments with fluorescent markers. In our ongoing research
in this area we plan to conduct fluorescence imaging in-vivo studies with
Indocyanine Green injections. These injections will be used in these studies to
further enhance the visual imaging of a suspicious lesion in the breast. We have
been granted FDA approval to conduct this study, using a maximum of 50 test
subjects, at a clinical site and we will begin this study once we have obtained
approval from the review boards of the medical institutions we have selected as
possible sites.

On February 22, 2000 we received notice from the U.S. Department of Commerce,
Patent and Trademark Office that our patent application for our breast perimeter
technique had been granted. The Patent No. is 6,029,077.

Clinical Update

On November 16, 1999, we announced our agreement with the University of Virginia
Health System as the second approved testing site. The FDA approved protocol
under the Investigational Device Exemption provides for 275 subjects, similar to
the Investigational Device Exemption protocol approved for Nassau County Medical
Center. The clinical investigational trials began on Monday, November 15, 1999.

                                  Risk Factors

         An investment in the common stock offered is highly speculative and
involves a high degree of risk. Accordingly, you should consider all of the risk
factors discussed below, as well as the other information contained in this
document. You should not invest in our common stock unless you can afford to
lose your entire investment and you are not dependent on the funds you are
investing.

                   Risks associated with our financial results

We have and are incurring significant losses and we may not be able to continue
our business in the future.


At December 31, 1999, we had an accumulated deficit of approximately
$37,709,561, after discounts and dividends on preferred stock. These losses have
resulted principally from costs associated with research and development,
clinical trials and from general and administrative costs associated with our
operations. We expect operating losses will increase for at least the next
several years due primarily to the anticipated expenses associated with:

o    development,
o    clinical trials,
o    pre-market approval process,
o    anticipated commercialization of the CTLM(TM), and
o    other research and development activities that may arise.


We have a limited history of operations. Since our inception in December 1993,
we have been engaged principally in the development of the CTLM(TM), which has
not been approved for sale in the United States. In addition, we have not
applied to the FDA for export approval for foreign sales. Consequently, we have
little experience in manufacturing, marketing and selling our products. We
currently have no source of operating revenue and have incurred net operating
losses since inception.

Our auditor's have raised substantial doubts as to our ability to continue as a
going concern as we have not been and may not be able to be profitable.

We have received an opinion from our auditors stating that the fact that we have
suffered substantial losses and have yet to generate an internal cash flow
raises substantial doubt about our ability to continue as a going concern. Our
ability to achieve profitability will depend on our ability to obtain regulatory
approvals for the CTLM(TM), develop the capacity to manufacture and market the
CTLM(TM), either by our self or in collaboration with others and market
acceptance of the CTLM(TM). However, there can be no assurance we will achieve
profitability if and when we receive regulatory approvals for the development,
commercial manufacturing and marketing of the CTLM(TM).

                    Risks associated with our lack of capital

We require additional capital which we may be unable to raise which may cause us
to stop or cut back our operations.


Through February 28, 2000 we have spent approximately $37 million and expect to
spend another $4.2 million in order to bring the CTLM(TM) into the United States
market. After receiving pre-market approval from the FDA, we anticipate that we
will need approximately $9.0 million over the next two years to complete all
necessary stages in order to market the CTLM(TM) in the United States and
foreign countries. At present we do not have the required capital to do this and
will require substantial additional funds to market this product, including
funds for:


o    clinical testing of the CTLM(TM)device,
o    research, engineering and development programs,

                                       6
<PAGE>


o    pre-clinical and clinical testing of other proposed products,
o    regulatory processes,
o    inventory, such as sub-contracted components,
o    manufacturing and marketing programs, and
o    operating expenses (including general and administrative expenses).


Our future capital requirements depend on many factors, including the following:

o    the progress of our research and development projects,
o    the progress of pre-clinical and clinical testing,
o    the time and cost involved in obtaining regulatory approvals,
o    the cost of filing, prosecuting, defending and enforcing any patent claims
     and other intellectual property rights; competing technological and market
     developments; changes and developments in our existing collaborative,
     licensing and other relationships and the terms of any new collaborative,
     licensing and other arrangements that we may establish, and
o    the development of commercialization activities and arrangements.

In addition, our fixed commitments are substantial and would increase if
additional agreements were entered into and additional personnel were retained.
We do not expect to generate a positive internal cash flow for at least several
years due to expected increases in capital expenditures, working capital needs,
and ongoing losses. There can be no assurance that additional financing will be
available when needed, or if available, will be available on acceptable terms.
We have already granted a mortgage on our corporate property as security for a
debenture and in all likelihood, would be unable to use this property to
collateralize any additional financing. Insufficient funds may prevent us from
implementing our business strategy and will require us to further delay, scale
back or eliminate our research, product development and marketing programs; and
may require us to license to third parties rights to commercialize products or
technologies that we would otherwise seek to develop ourselves, or to scale back
or eliminate our other operations.


We have had and may have to issue securities for services which may further
depress our stock price and dilute the holdings of our shareholders.

Since we have generated no revenues to date, our ability to obtain and retain
consultants may be dependent on our ability to issue stock for services. Since
July 1, 1996, we have issued an aggregate of 1,806,500 shares of common stock
according to registration statements on Form S-8. The aggregate fair market
value of the shares when issued was $2,327,151. The issuance of large amounts of
our common stock for services rendered or to be rendered and the subsequent sale
of these shares may further depress the price of our common stock and dilute the
holdings of our shareholders. In addition, because of the possible dilution to
existing shareholders, the issuance of substantial additional shares may cause a
change-in-control.

We have in the past and may have to in the future sell additional unregistered
securities, possibly without limitations on the number of common shares the
securities are convertible into, which could dilute the value of the holdings of
current shareholders.

We have had to and have to rely on the private placement of preferred and common
stock and convertible debentures to obtain working capital and will continue to
do so in the future. As of the date of this registration statement, we have
issued 55,979,558 shares of common stock which were converted from preferred
stock and debentures that we privately placed. This number of shares of common
stock represents approximately 57.6%of the currently outstanding number of
shares of common stock.

In deciding to issue preferred stock and debentures through private placements,
we took into account:


o    the number of common shares authorized and outstanding,
o    the market price of the common stock at the time of each preferred or
     debenture sale and
o    the number of common shares the preferred stock would have been convertible
     into at the time of the sale.

                                       7
<PAGE>

At the time of each private placement there were enough shares, based on the
price of our common stock at the time of the sale of the preferred stock to
satisfy the preferred conversion requirements. Although our board of directors
tried to negotiate a floor on the conversion price of each series of preferred
stock and the debentures prior to their sale, it was unable to do so.

Manipulation of our common stock through short sales and offers to sell our
preferred stock at a substantial discount may artificially depress our stock
price. These types of transactions are sometimes referred to as "toxic"
securities. After the stock is manipulated and the price is driven down, the
preferred stock is then converted which may give the preferred shareholder
control over a substantial percentage of the public float of our stock.

In order to obtain working capital we will continue to:

o    seek capital through debt or equity financing which may include the
     issuance of convertible preferred stock whose rights and preferences are
     superior to those of the common stock holders, and
o    try to negotiate the best transaction possible taking into account the
     impact on our shareholders, dilution, loss of voting power and the
     possibility of a change-in-control.

However, in order to satisfy our working capital needs, we may be forced to
issue convertible securities with no limitations on conversion.


In the event that we issue convertible preferred stock or convertible debentures
without a limit on the number of shares that can be issued upon conversion and
the price of our common stock decreases:

o    the percentage of shares outstanding that will be held by these holders
     upon conversion will increase accordingly,
o    the lower the market price the greater the number of shares to be issued to
     these holders upon conversion, thus increasing the potential profits to the
     holder when the price per share then increases and the holder sells the
     common shares,
o    the preferred stockholders' and debenture holders potential for increased
     share issuance and profit, including profits derived from shorting our
     common stock, in addition to a stock overhang of an indeterminable amount,
     may depress the price of our common stock,
o    the sale of a substantial amount of preferred stock to relatively few
     holders could effectuate a possible change-in-control and
o    in the event of our voluntarily or involuntarily liquidation while the
     preferred stock is outstanding, the holders will be entitled to a
     preference in distribution of our property.

We may draw on our equity credit line which may cause the value of our common
stock to decline and dilute the holdings of our shareholders.


We have a firm commitment for a $15.0 Million, three-year equity line of credit.
Pursuant to the equity line of credit, when we feel it necessary, we may raise
capital through the sale of our common stock to a consortium of prominent
European banking institutions. In order to use the equity credit line, our
common stock must trade above $.50 per share. We would also be required to file
a shelf registration statement or other registration that may be available to
us. We may need capital in excess of the equity line of credit or if we decline
to use the equity line of credit, we may seek additional funding through public
or private financing or collaborative, licensing and other arrangements with
corporate partners. If we utilize the equity line of credit or additional funds
are raised by issuing equity securities, especially convertible preferred stock,
dilution to existing shareholders will result and future investors may be
granted rights superior to those of existing shareholders.

We have had and may have to issue securities in order to pay off our debts which
may further depress our stock price and dilute the holdings of our shareholders.

Since we have generated no revenues to date, we have had difficulty in paying
off some of our debts which have become due. In order to pay these debts, we
have issued shares of common stock. For example, since the beginning of December
30, 1999, we have paid off approximately $532,100 in debt by issuing 3,129,811
shares of restricted


                                       8
<PAGE>

common stock. In addition, as we have little or no present revenues, we may have
to issue more shares of common stock in order to pay off current or future debts
which become due. This type of issuance of common stock to pay off debt may
further depress the price of our common stock and would dilute the holdings of
our shareholders, and if substantial dilution does occur, could also cause a
change-in-control.


Conversions of our convertible preferred stock and exercise of our convertible
debenture and warrants may cause other detrimental effects to the value of our
shareholders' holdings.

If the market price declines significantly, we could be required to issue a
number of shares of common stock sufficient to result in our current
stockholders not having an effective vote in the election of directors and other
corporate matters. In the event of a change-in-control, it is possible that the
new majority stockholders may take actions that may not be consistent with the
objectives or desires of our current stockholders.



We are required to convert the convertible preferred stock and convertible
debenture based on a formula that varies with the market price of our common
stock. As a result, if the market price of our common stock increases after the
issuance of our convertible preferred stock and convertible debenture, it is
possible that, upon conversion of the convertible preferred stock and
convertible debenture, we will issue shares of common stock at a price that is
less than the then-current market price of the common stock.

If the market price of our common stock decreases after we issue the convertible
preferred stock or convertible debenture, upon conversion, we will have to issue
an increased number of shares to the preferred stock and convertible debenture
holder. The sale of convertible preferred stock and debentures may result in a
very large conversion at one time. If we do not have a sufficient number of
shares to cover the conversion we may have a risk of a civil lawsuit.

In addition, the warrants we issued are exercisable at a fixed price. If the
market price of our common stock increases above the warrant exercise price, we
will be required to issue shares of common stock upon exercise of the warrants
at a price that is less than the then-current market price. Issuances at less
than market price pose a risk to investors because these issuances may drive
down the market price of our common stock.

                       Risks associated with our industry

We depend on market acceptance to sell our products which have not been proven
and may not occur which would depress our sales.

There can be no assurance that physicians or the medical community in general,
will accept and utilize the CTLM(TM) or any other products that we develop. The
extent and rate the CTLM(TM) achieves market acceptance and penetration will
depend on many variables, including, but not limited to:

o    the establishment and demonstration in the medical community of the
     clinical safety, efficacy and cost-effectiveness of the CTLM(TM),
o    the advantages of the CTLM(TM)over existing technology and cancer detection
     methods, including:
         -        X-ray mammography,
         -        Ultrasound or high frequency ultrasound,
         -        MRI,
         -        Thermography,
         -        Diaphonography,
         -        Electrical impedance, and
         -        Transillumination devices
o    third-party reimbursements practices, and
o    our manufacturing, quality control, marketing and sales efforts.

There can be no assurance that the medical community and third-party payers will
accept our unique technology. Similar risks will confront any other products we
develop in the future. Failure of our products to gain market

                                       9
<PAGE>

acceptance would hinder our sales efforts resulting in a loss of revenues and
net profit. It would further prevent us from developing new products.

Lack of third-party reimbursement may have a negative impact on the sales of our
products which would negatively impact our revenues.

In the United States, suppliers of health care products and services are greatly
affected by Medicare, Medicaid and other government insurance programs, as well
as by private insurance reimbursement programs. Third-party payers (Medicare,
Medicaid, private health insurance companies, and other organizations) may
affect the pricing or relative attractiveness of our products by regulating the
level of reimbursement provided by these payers to the physicians, clinics and
imaging centers utilizing the CTLM(TM) or any other products that we may
develop, by refusing reimbursement. The level of reimbursement, if any, may
impact the market acceptance and pricing of our products, including the
CTLM(TM). Failure to obtain favorable rates of third-party reimbursement could
discourage the purchase and use of the CTLM(TM) as a diagnostic device.

In international markets, reimbursement by private third-party medical insurance
providers, including governmental insurers and independent providers varies from
country to country. In addition, such third-party medical insurance providers
may require additional information or clinical data prior to providing
reimbursement for a product. In some countries, our ability to achieve
significant market penetration may depend upon the availability of third-party
governmental reimbursement. Revenues and profitability of medical device
companies may be affected by the continuing efforts of governmental and third
party payers to contain or reduce the cost of health care through various means.

There are uncertainties regarding healthcare reform including possible
legislation, whereby our customers may not receive medical reimbursement for the
use of our product on their patients, which may cause our customers to use other
services and products.

Several states and the United States government are investigating a variety of
alternatives to reform the health care delivery system. These reform efforts
include proposals to limit and further reduce and control health care spending
on health care items and services, limit coverage for new technology and limit
or control the price health care providers and drug and device manufacturers may
charge for their services and products, respectively. If adopted and
implemented, these reforms could cause our healthcare providers to limit or not
use the CTLM(TM) systems.

Competition in the medical imaging industry may result in competing products,
superior marketing and lower revenues and profits for us.

The market in which we intend to participate is highly competitive. Many of the
companies in the cancer diagnostic and screening markets have substantially
greater technological, financial, research and development, manufacturing, human
and marketing resources and experience than we do. These companies may succeed
in developing, manufacturing and marketing products that are more effective or
less costly than our products. Physicians using imaging equipment such as x-ray
mammography equipment, ultrasound or high frequency ultrasound systems, magnetic
resonance imaging systems, and thermography, diaphonography and
transilluminational devices may not use our products. Currently mammography is
employed widely and our ability to sell the CTLM(TM) to medical facilities will,
partially depend on our ability to demonstrate the clinical utility of the
CTLM(TM) as an adjunct to mammography and physical examination and its
advantages over other available diagnostic tests. The competition for developing
a commercial device utilizing computed tomography techniques and laser
technology is difficult to ascertain given the proprietary nature of the
technology. There are a significant number of academic institutions involved in
various areas of research involving "optical medical imaging" which is a
shorthand description of the technology our CTLM(TM) utilizes.

                      Risks associated with our securities

Our common stock is considered "penny stock" and may be difficult to sell.

The SEC has adopted regulations, which generally define "penny stock" to be an
equity security that has a market price of less than $5.00 per share or an
exercise price of less than $5.00 per share, subject to specific exemptions.
Presently, the market price of our common stock is substantially less than $5.00
per share and therefore may be designated as a "penny stock" according to SEC
rules. This designation requires any broker or dealer selling these securities
to disclose certain information concerning the transaction, obtain a written
agreement from the purchaser and determine that the purchaser is reasonably
suitable to purchase the securities. These rules may restrict the ability of
brokers or dealers to sell our common stock and may affect the ability of
investors to sell their shares. In addition, since our common stock is traded on
the NASDAQ OTC Bulletin Board, investors may find it difficult to obtain
accurate quotations of our common stock.

The volatility of our stock price could adversely affect your investment in our
common stock.

The price of our common stock has fluctuated substantially since it began
trading on the OTC Bulletin Board in September 1994. The market price of our
shares, like that of the common stock of many other medical device companies, is
likely to continue to be highly volatile. Factors that may have an impact on the
price of our common stock include:

o    the timing and results of our clinical trials or our competitors,
o    governmental regulation,
o    healthcare legislation,
o    equity or debt financing, and
o    developments in patent or other proprietary rights pertaining to our
     competitors or us, including litigation, fluctuations in our operating
     results, and market conditions for medical device company stocks and life
     science stocks in general.

We may issue preferred stock at any time to prevent a takeover or acquisition,
any of which issuance could dilute the price of our common stock.

Our articles of incorporation authorize the issuance of preferred stock with
designations, rights, and preferences that may be determined from time to time
by the board of directors. Our board of directors is empowered, without
stockholder approval, to designate and issue additional series of preferred
stock with dividend, liquidation, conversion, voting and other rights, including
the right to issue convertible securities with no limitations on conversion,
which could adversely affect the voting power or other rights of the holders of
our common stock. This could substantially dilute the common shareholder's
interest and depress the price of our common stock. In addition, the preferred
stock could be utilized, as a method of discouraging, delaying or preventing a
change-in-control. The substantial number of issued and outstanding convertible
preferred stock and the convertible debentures, and their terms of conversion
may discourage or prevent an acquisition of our company


Although we have increased the number of shares of our authorized common stock
in order to help facilitate the conversion and exercise of outstanding and
future preferred stock and other securities, which conversion and exercise would
depress the value of our common stock and dilute shareholdings, we still may not
have enough authorized common stock available to convert the debentures and the
outstanding Series B and I preferred stock into common stock.

According to a written action of a majority of our shareholders, we have amended
our articles of incorporation, to increase our authorized common stock from
48,000,000 shares to 100,000,000 shares in order to facilitate the conversion of
our outstanding preferred stock and debentures. Prior to the amendment, we did
not have an adequate number of shares authorized to meet our contractual
obligations due to the decrease in our stock price. Furthermore, as our stock
price continues to fluctuate, even with this increase in the authorized common
stock, we may still not be able to convert into common stock the debentures and

                                       11
<PAGE>

the Series B and I preferred stock which could cause us to accrue liquidated
damages under our registration rights agreement. The holder, Charlton Avenue
LLC, has waived its rights to any liquidated damages in may have in connection
with these securities through April 30, 2000. As long as we have outstanding
securities convertible into common stock at a price dependent on the market
price of the common stock, we may have to increase our authorized common stock
in order to have the available authorized common stock for conversions of these
convertible securities, which would result in further dilution to our existing
stockholders.

In addition, until the time when we are able to generate revenues, we are
dependent on equity or other financing to continue operations and the amendment
affords us common stock to finance our operations through equity financings,
which we will continue to do, as we will require substantial additional funds
for our operations. We may again be obligated to increase our authorized common
stock from 100,000,000 shares to 150,000,000 to facilitate the conversion of our
outstanding preferred stock and debentures.

Based on the closing price of our common stock as of February 28, 2000, of
$3.8438 per share, approximately:

o    177,111 shares would be required to convert the Series B shares,
o    2,466,953 shares would be required to convert the Series I shares,
o    1,010,482 shares would be required to convert the debentures and
o    although we are contractually prohibited from doing so, 4,877,985 shares
     would be required to draw down the entire equity line of credit.

In addition, 4,990,318 shares would be required for the exercise of options and
warrants. Based upon this information, as of February 28, 2000, we would need in
excess of approximately 10 million authorized shares for all conversions,
complete utilization of the equity line of credit and fulfillment of our
remaining stock related obligations.

We currently are controlled by our executive officers and directors, however, if
outstanding preferred stock and debentures are converted, a change-in-control
may occur.

Our management beneficially owns 21.9% including options, of our outstanding
common stock, assuming no exercise of outstanding warrants, options, or
conversion of preferred stock. Although management owns less than 50.1% of the
outstanding common stock, since we do not have cumulative voting, and since, in
all likelihood the officers will be voting as a block and will be able to obtain
proxies of other shareholders, management should continue to remain in a
position to elect all of our directors and control our policies and operations.
However, after giving effect to the conversion of the preferred stock and
debentures, management would own only 20.5% as of February 28, 2000. This
additional dilution to management's ownership percentage could cause a
change-in-control.


We have not paid and do not currently intend to pay dividends, which may limit
the current return you may receive on your investment in our common stock.

Since inception, we have not paid a dividend on our common stock and do not
intend to pay dividends on our common stock in the foreseeable future.

                      Risks associated with our technology

We depend on a patent licensed to us by our founder without which our operations
would cease.


We own the rights, through an exclusive patent licensing agreement, for the use
of the patent for the CTLM(TM) technology. Richard Grable owns the patent. In
addition, we have 10 additional United States patents pending with regard to
optical tomography, many of which are based on the original CTLM(TM) technology.
In the event that we breach the patent licensing agreement, we could lose the
licensing rights to the CTLM(TM) technology. The loss of the patent license
would have a material adverse effect on us and our continued operations.


                                       12
<PAGE>


Our business would lose its primary competitive advantage if we are unable to
protect our proprietary technology, or if substantially the same technology is
developed by others.


We rely primarily on a combination of trade secrets, patents, copyright and
trademark laws, and confidentiality procedures to protect our technology.

Our ability to compete effectively in the medical imaging products industry will
depend on our success in protecting our proprietary technology, both in the
United States and abroad. There can be no assurances that any patent that we
apply for will be issued, or that any patents issued will not be challenged,
invalidated, or circumvented, or that the rights granted will provide any
competitive advantage. Neither we nor Mr. Grable hold foreign patents, however,
we have applied for patents in several foreign countries. We could incur
substantial costs in defending any patent infringement suits or in asserting any
patent rights, including those granted by third parties, the expenditure of
which we might not be able to afford.

Although we have entered into confidentiality and invention agreements with our
employees and consultants, there can be no assurance that these agreements will
be honored or that we will be able to protect our rights to our non-patented
trade secrets and know-how effectively. There can be no assurance that others
will not independently develop substantially equivalent proprietary information
and techniques or otherwise gain access to our trade secrets and know-how. In
addition, we may be required to obtain licenses to patents or other proprietary
rights from third parties. If we do not obtain required licenses, we could
encounter delays in product development or find that the development,
manufacture, or sale of products requiring these licenses could be foreclosed.
Additionally, we may, from time to time, support and collaborate in research
conducted by universities and governmental research organizations. There can be
no assurance that we will have or be able to acquire exclusive rights to the
inventions or technical information derived from such collaborations or that
disputes will not arise with respect to rights in derivative or related research
programs that we conducted in conjunction with these organizations.


It may be necessary to enter into unfavorable agreements or defend law suits
which would be costly if we infringe upon the intellectual property rights of
others.


There has been substantial litigation regarding patent and other intellectual
property rights in the medical device and related industries. We have been, and
may be in the future, notified that we may be infringing on intellectual
property rights possessed by other third parties. If any claims are asserted
against our intellectual property rights, we may seek to enter into royalty or
licensing arrangements. There is a risk in situations that no license will be
available or that a license will not be available on reasonable terms.
Alternatively, we may decide to litigate these claims or design around the
patented technology. These actions could be costly and would divert the efforts
and attention of our management and technical personnel. Consequently, any
infringement claims by third parties or other claims for indemnification by
customers resulting from infringement claims, whether or not proven to be true,
may be costly to defend and may further limit the use of our technology.

We may not be able to keep up with the rapid technological change in the medical
imaging industry which could make the CTLM(TM) obsolete.

Methods for the detection of cancer are subject to rapid technological
innovation and there can be no assurance that technical changes will not render
our proposed products obsolete. Although we believe that the CTLM(TM) can be
upgraded to maintain its state-of-the-art character, the development of new
technologies or refinements of existing ones might make our existing system
technologically or economically obsolete, or cause a reduction in the value of,
or reduce the need for, our CTLM(TM). There can be no assurance that the
development and commercial availability of new types of diagnostic medical
equipment or technology will not have a material adverse effect on our business,
financial condition, and results of operations. Although we are aware of no
substantial technological changes pending, should a change occur, there can be
no assurance that we will be able to acquire the new or improved systems which
may be required to update the CTLM(TM).

                                       13
<PAGE>

                       Risks associated with our business


We may not find sufficient facilities to adequately test the CTLM(TM) and, in
addition, clinical trials done at any of these facilities may not be successful,
which may keep us from receiving FDA approval.

We currently have two CTLM(TM) functioning and being tested, one in Nassau
County Medical Center and one in the University of Virginia Health System,
pursuant to investigational device exemptions granted by the FDA. The testing is
designed to develop diagnostic criteria for CTLM(TM) images. We have entered
into discussions with several hospitals, which are located throughout the United
States for further potential clinical test sites. The remaining proposed sites
have indicated an interest in participating in our clinical trials, however, we
do not anticipate a formal response until February 2000 at which point we would
have to request permission from the FDA to expand our clinical trials. The
delays are due to the time required for site surveys, locating available rooms
for the CTLM(TM) in the hospitals, subsequent room renovations and the hiring
and training of additional clinical application specialists. Furthermore, the
approval boards of some hospitals only meet once per month approval may be
further delayed. At the conclusion of the clinical trials we will submit the
pre-market approval application for the CTLM(TM).


Furthermore, there can be no assurance that:

o    results obtained in any additional trials will be consistent with the
     results obtained in trials conducted by us to date;
o    results obtained in any clinical trial or series of clinical trials will be
     consistent among all study sites, or
o    results obtained in clinical trials conducted with U.S. study populations
     will be consistent with results obtained in studies conducted in Europe or
     other locations outside of the U.S.

We must comply with extensive government regulation and have no assurance of
regulatory approvals or clearances which could cause us to cut back or cease
operations.

Our delay or inability to obtain any necessary United States, state or foreign
regulatory clearances or approvals for our products would prevent us from
selling the CTLM(TM) system in the U.S. and other countries.

In the United States, the CTLM(TM) is regulated as a medical device and is
subject to the FDA's pre-market clearance or approval requirements. To obtain
FDA approval of an application for pre-market approval, the pre-market approval
application must demonstrate that the subject device has clinical utility,
meaning that the device has a beneficial therapeutic effect, or that as a
diagnostic tool it provides information that measurably contributes to a
diagnosis of a disease or condition.

We cannot file our pre-market approval application for the CTLM(TM) until our
clinical trials are completed. There can be no assurance, that our clinical
trials will be successfully completed, or if completed, will provide sufficient
data to support a pre-market approval application for the CTLM(TM); nor can
there be any assurance that the FDA will not require us to conduct additional
clinical trials for the CTLM(TM), which would delay the CTLM(TM) coming onto the
market.


In addition, sales of medical devices outside the United States may be subject
to international regulatory requirements that vary from country to country. The
time required to gain approval for international sales may be longer or shorter
than required for FDA approval and the requirements may differ. For example, in
order to sell our products within the European economic area, companies are
required to achieve compliance with the requirements of the medical devices
directive and affix a "CE" marking on their products to attest compliance. We
are in preliminary preparations regarding CE certification in Europe which
certification would allow us to conduct sales in member countries of the
European Union.

As of the date of this prospectus, we have not yet obtained these international
certifications and there can be no assurance that we will be able to do so.

Regulatory approvals, if granted, may include significant limitations on the
indicated uses for which the CTLM(TM) may be marketed. In addition, to obtain
these approvals, the FDA and certain foreign regulatory authorities may impose
numerous other requirements which medical device manufacturers must comply with.
FDA enforcement policy strictly prohibits the marketing of approved medical
devices for unapproved uses. Product approvals could be withdrawn for failure to
comply with regulatory standards or the occurrence of unforeseen problems
following initial marketing.

The third-party manufacturers upon which we will depend to manufacture our
products are required to adhere to applicable FDA regulations regarding, quality
systems regulations commonly referred to as QSR,s, which include testing,
control and documentation requirements Failure to comply with applicable
regulatory requirements, including marketing and promoting products for
unapproved use, could result in warning letters, fines, injunctions, civil
penalties, recall or seizure of products, total or partial suspension of
production, refusal of the government to grant pre-market clearance or approval
for devices, withdrawal of approvals and criminal prosecution. Changes in
existing regulations or adoption of new government regulations or polices could
prevent or delay regulatory approval of our products. Material changes to
medical devices also are subject to FDA review and clearance or approval.

In addition, unapproved products subject to the pre-market approval requirements
must receive prior FDA export approval in order to be marketed outside of the
United States unless they are approved for use by any member country of the
European Union or certain other countries, including Australia, Canada, Israel,
Japan, New Zealand, Switzerland and South Africa, in which case the products can
be exported to any country provided that limited notification requirements are
met. There can be no assurance that we will meet the FDA's export requirements
or receive FDA export approval when our approval is necessary, or that countries
to which the devices are to be exported will approve the devices for import. Our
failure to meet the FDA's export requirements or obtain FDA export approval when
required to do so, or to obtain approval for import, could have a material
adverse effect on our business, financial condition, cash flows and results of
operations.

There can be no assurance that we will be able to obtain or maintain the
following:

o    FDA approval of a pre-market approval application for the CTLM(TM),
o    foreign marketing clearances for the CTLM(TM)or regulatory approvals or
     clearances for other products that we may develop, on a timely basis, or at
     all,
o    timely receipt of approvals or clearances,
o    continued approval or clearance of previously obtained approvals and
     clearances, and
o    compliance with existing or future regulatory requirements.

If we do not obtain or maintain any of the above-mentioned standards, there may
be material adverse effects on our business, financial condition and results of
operations.

We may not be able to develop other products that are currently in the early
stages of development due to our need for additional capital.

Due to our need for additional capital, our proposed products, other than the
CTLM(TM) device, including a scanner for the early detection of colon cancer,
are at early stages of development. There can be no assurance that any of our
proposed products will be, including the CTLM(TM):

o    found to be safe and effective,
o    meet applicable regulatory standards or receive necessary regulatory
     clearance,
o    or if safe and effective, can be developed into commercial products,
     manufactured on a large scale or be economical to market, or
o    achieve or sustain market acceptance.

Therefore, there is substantial risk that our product development and
commercialization efforts will not prove to be successful for our products.

                                       15
<PAGE>

We will depend on a single product, the CTLM(TM), for our revenue in the next
few years, any problems with which would cause adverse affects to our business.

We are in the process of developing additional products based on our main
technology, including an enhancement of the CTLM(TM) device for use with
fluorescence contrast agents and photo-dynamic therapy drugs. Photo-dynamic
therapy drugs seek out cancer and are activated by light. Neither application is
expected to result in a commercial product for at least several years, if at
all. Consequently, pending its approval for commercial distribution in the
United States, the CTLM(TM) device would account for substantially all of our
revenues for at least the next two years. Failure to gain regulatory approvals
or market acceptance for the CTLM(TM) device would prevent the sale of the
CTLM(TM) device in the U.S. and other countries adhering to FDA approved
guidelines.

We depend upon suppliers with whom we have no contracts which suppliers could
cause production disruption if they terminated or changed their relationships
with us.

We believe that there are a number of suppliers for most of the components and
subassemblies required for the CTLM(TM). Particular components for our laser
system are provided by two unrelated suppliers. Although these components are
provided by a limited number of other suppliers, we believe our laser suppliers
and their products are the most reliable. We have no agreement with our laser
suppliers and purchase the laser components on an as needed basis. For certain
services and components, we currently rely on single suppliers. If we encounter
delays or difficulties with our third-party suppliers in producing, packaging,
or distributing components of the CTLM(TM) device, market introduction and
subsequent sales would be adversely affected.

We have no experience in sales, marketing and distribution which could
negatively impact our ability to enter into collaborative arrangements or other
third party relationships which are important to the successful development and
commercialization of our products and potential profitability.

We have limited internal marketing and sales resources and personnel. There can
be no assurance that we will be able to establish sales and distribution
capabilities or that we will be successful in gaining market acceptance for any
products we may develop. There can be no assurance that we will be able to
recruit and retain skilled sales, marketing, service or support personnel, that
agreements with distributors will be available on terms commercially reasonable
to us, or at all, or that our marketing and sales efforts will be successful.

There can be no assurance that we will be able to further develop our
distribution network on acceptable terms, if at all or that any of our proposed
marketing schedules or plans can or will be met.

We depend on qualified personnel to run and develop our specialized business who
we may be unable to retain or hire.

Due to the specialized scientific nature of our business, we are highly
dependent upon our ability to attract and retain qualified scientific, technical
and managerial personnel. We have entered into employment agreements with some
of our executive officers and key employees. The loss of the services of
existing personnel, especially Mr. Grable, as well as the failure to recruit key
scientific, technical and managerial personnel in a timely manner would be
detrimental to our research and development programs and could have an adverse
impact upon our business affairs and finances. Our anticipated growth and
expansion into areas and activities requiring additional expertise, such as
marketing, will require the addition of new management personnel. Competition
for qualified personnel is intense and there can be no assurance that we will be
able to continue to attract and retain qualified personnel necessary for the
development of our business.

We have a possible conflict of interest in our management which could cause us
to enter into agreements on less favorable terms than we may otherwise get.

Richard Grable and Linda Grable hold a majority of the seats on our board of
directors. Consequently, they are in a position to control their own
compensation and to approve affiliated transactions. For example, in June 1998,

                                       16
<PAGE>

we finalized an exclusive patent license agreement with Richard Grable. The
board's policy is to obtain unanimous consent for affiliated transactions and
compensation issues. Although our board intends to act fairly and in full
compliance with its fiduciary obligations, there can be no assurance that we
will not, as a result of the conflict of interest described above, enter into
arrangements under terms less favorable than those which we could have obtained
had we been dealing with unrelated persons.

We have a limited manufacturing history which could cause delays in the
production and shipment of our product.

We will have to expand our CTLM(TM) manufacturing and assembly capabilities and
contract for the manufacture of the CTLM(TM) components in volumes that will be
necessary for us to achieve significant commercial sales in the event we begin
foreign sales and/or obtain regulatory approval to market our products in the
United States. We have limited experience in the manufacture of medical products
for clinical trials or commercial purposes. Should we manufacture our products,
our manufacturing facilities would be subject to the full range of the FDA's
current quality system regulations, and we would need additional capital to
establish these types of facilities. In addition, there can be no assurance that
we would be able to manufacture our products successfully or cost-effectively.

We depend on third parties who may not be in compliance with the FDA's quality
system regulations which may delay the approval or decrease the sales of the
CTLM(TM).

We have used and do use third parties to manufacture and deliver the components
of the CTLM(TM) and intend to continue to use third parties to manufacture and
deliver these components and other products we may develop. There can be no
assurance that the third-party manufacturers we depend on for the manufacturing
of CTLM(TM) components will be in compliance with the quality system regulations
at the time of the pre-approval inspection or will maintain compliance
afterwards. This failure could significantly delay FDA approval of the
pre-market approval application for the CTLM(TM) device.

We have had and may have delays in getting our products to market both
domestically and internationally which have hindered and may hinder our sales.

Originally, we anticipated that the CTLM(TM) would be ready for distribution in
the summer of 1998, however, during the course of clinical trials, we learned of
problems with particular components of the CTLM(TM) that needed to be corrected
before distribution. Solutions to these problems had to be found and adjustments
had to be made to the CTLM(TM) to correct these problems. Specifically, the
laser components, the electronic technology involved in image acquisition and
the fiber optics had to be modified.


As of the date of this prospectus, our Canadian distributor has placed an order
for two CTLM(TM) systems to be delivered in late March 2000. We are currently
preparing the necessary documents required for FDA export approval to Canada. We
intend to continue to sell CTLM(TM) systems through distributors in those
countries where sales are permitted. No CTLM(TM) systems have been sold pursuant
to an investigational device exemption in the United States market.


We will rely on international sales and may be subject to risks associated with
international commerce.

We intend to commence international sales of the CTLM(TM) in Canada, Europe and
Asia, prior to commencing commercial sales in the U.S. Until we receive
pre-market approval from the FDA to market the CTLM(TM) in the United States,
our revenues, if any, will be derived from sales to international distributors.
A significant portion of our revenues may be subject to the risks associated
with international sales, including:

o    economical and political instability,
o    shipping delays,
o    fluctuation of foreign currency exchange rates,
o    foreign regulatory requirements, and

                                       17
<PAGE>

o    various trade restrictions, all of which could have a significant impact on
     our ability to deliver products on a timely basis.

Significant increases in the level of customs duties, export quotas or other
trade restrictions could have a material adverse effect on our business,
financial condition and results of operations. The regulation of medical
devices, particularly in Europe, continues to develop and there can be no
assurance that new laws or regulations will not have an adverse effect on us. In
order to minimize the risk of doing business with distributors in countries
which are having difficult financial times, our international distribution
agreements all require payment via an irrevocable letter of credit drawn on a
United States bank prior to shipment of the CTLM(TM).

Our business has the risk of product liability claims and preferred insurance
coverage may be expensive or unavailable which may expose us to material
liabilities.

Our business exposes us to potential product liability risks, which are inherent
in the testing, manufacturing, and marketing of cancer detection products.
Significant litigation, not involving us, has occurred in the past based on the
allegations of false negative diagnoses of cancer. While the CTLM(TM) device is
being developed as an adjunct to other diagnostic techniques, there can be no
assurance that we will not be subjected to future claims and potential
liability. Although the FDA does not require product liability insurance with
regard to clinical investigations, we obtained and presently carry product
liability insurance in the amount of $3,000,000, at the request of Nassau
County. While we plan to maintain insurance against product and professional
liability and defense costs, there can be no assurance that claims against us
arising with respect to our products will be successfully defended or that the
insurance to be carried by us will be sufficient to cover liabilities arising
from any claims. A successful claim against us in excess of our insurance
coverage could have a material adverse effect on us. Furthermore, there can be
no assurance that we will be able to continue to obtain or maintain product
liability insurance on acceptable terms.

We lack a feasibility study and do not know if sufficient demand exists for our
product.

We have not performed any market or feasibility study to assess the interest,
demand, or need for the CTLM(TM). There can be no assurance that a study would
support management's belief that sufficient demand will exist.

Stock Option Plans

For the fiscal year ended June 30, 1999, all of our executive officers were
participants in our 1995 stock option plan. The plan was approved by our board
of directors and adopted by the shareholders at the March 29, 1995 annual
meeting. The plan provides for the granting, exercising and issuing of incentive
options pursuant to Internal Revenue Code, Section 422. We may grant incentive
stock options to purchase up to 5% of our issued and outstanding common stock at
any time. Our board of directors has direct responsibility for the
administration of the plan.

On August 30, 1999, we established an equity incentive plan. The shareholders
must approve this plan within 1 year. The maximum number of shares that can be
granted under this plan is 15,000,000 shares of common stock and 5,000,000
shares of preferred stock. The series, rights and preferences of the preferred
stock are to be determined by our board of directors. This plan also includes
any stock available for future stock rights under our 1995 stock option plan.

Under both of these plans, the exercise price of the incentive options to
employees must be equal to at least 100% of the fair market value of the common
stock, as of the date of grant. The exercise price of incentive options to
officers, or affiliated persons, must be at least 110% of the fair market value
as of the date of grant.

According to stock option agreements, Mr. Richard J. Grable, Mr. Allan L.
Schwartz and Mrs. Linda B. Grable each have an option to purchase 2,500,000
shares of common stock or preferred stock. These options vest in equal
installments over a five-year period at an exercise price of $.21 per share
(110% of the fair market value of the shares on the date of grant). These stock
option agreements terminate on August 30, 2003.

         Security Ownership of Certain Beneficial Owners and Management

The following table shows the beneficial ownership of our common stock as of
February 28, 2000 regarding:

(i)      each person that we know of who beneficially owns more than 5% of the
         outstanding shares of our common stock,
(ii)     each current director and executive officer, and

                 Certain Relationships and Related Transactions

Richard J. Grable and Linda B. Grable are husband and wife. They are each
"control persons" as a result of their control of a majority voting power of our
outstanding stock. Both parties disclaim, however, any beneficial interest or
ownership in the shares owned by the other party.


In September and October 1998, Linda Grable, our president, personally
guaranteed three promissory notes we issued to third parties. Ms. Grable
received no compensation for these guarantees. As of the date of the
registration statement, all three notes have been repaid.


In June 1998, we finalized an exclusive patent license agreement with Richard
Grable. Mr. Grable is the owner of the patent, which encompasses the technology
for the CTLM(TM). Our company and Mr. Grable had previously entered into an oral
agreement for the exclusive license for the patent that was never memorialized
in written form. The term of the license is for the life of the patent (17
years) and any renewals, subject to termination, under specific conditions. As
consideration for this license, we issued to Mr. Grable 3,500,000 shares of
common stock and were required to issue to him an additional 3,500,000 shares in
June 1999. In addition, we have agreed to pay Mr. Grable a royalty based upon
the net selling price (the dollar amount earned from our sale, both
international and domestic, before taxes minus the cost of the goods sold and
commissions or discounts paid) of all products and goods in which the patent is
used, before taxes and after deducting the direct cost of the product and
commissions or discounts paid. During the second year of the agreement there is
a minimum cash royalty provision of $250,000 payable at the end of the second
year which Mr. Grable has deferred until we commence sales and delivery of
CTLM(TM) systems.


Since October 1998, we have accrued $87,440 in salaries payable to our executive
officers and directors, Richard J. Grable, Allan Schwartz and Linda B. Grable,
due to our lack of working capital.


In January 1999 and February 1999, Richard Grable, sold an aggregate of 831,743
shares of our common stock owned by him in excess of 4 years, according to Rule
144 and lent the aggregate proceeds of approximately $347,775 directly to us. In
January 1999, February 1999 and March 1999, Linda Grable, also sold an aggregate
of 520,000 shares of our common stock owned by her in excess of 4 years,
according to Rule 144 and lent the aggregate proceeds of approximately $166,618
directly to us and in December 1998, January 1999 and February 1999, Allan
Schwartz, sold an aggregate of 820,000 shares owned by him in excess of 4 years,
according to Rule 144 and lent the aggregate proceeds of approximately $359,707
directly to us. All of these loans were interest free and were evidenced by
promissory notes. These promissory notes were due on January 30, 1999, February
28, 1999, March 31, 1999, and April 30, 1999, respectively. The net proceeds
were recorded as a loan payable to each respective lender.

A meeting of our board of directors was held on May 12, 1999 to review and act
upon the previously adopted schedule of repayment of the loans, interest and
potential tax liability. Based on an opinion of the Grables' personal outside

                                       22
<PAGE>

counsel and upon advice of a tax advisor, our board voted to rescind the
previously adopted resolution. The new resolution authorized the repayment of
the December, January, February, and March promissory notes in full by the
issuance of shares equal to the number of shares sold. The restricted shares
issued as repayment for the loans bear registration rights. Since the loans were
repaid on a share for share basis with no other consideration, the Grables have
been advised that there is no capital gain and therefore no tax liability.
Messrs. Grable, Schwartz and Ms. Grable received 831,743, 820,000, and 520,000
shares of our restricted common stock, respectively, as payment in full for the
loans made between December 1998 and March 1999.

In May 1999, Messrs. Grable and Schwartz each sold 110,000 shares, respectively,
of our common stock owned by them in excess of 4 years, according to Rule 144
and lent the aggregate proceeds of approximately $91,759 directly to us. The
loans were evidenced by interest free promissory notes, which were due, and
payable on June 30, 1999. In June 1999, Messrs. Grable and Schwartz each sold
280,000 and 315,020 shares, respectively, of our common stock owned by them in
excess of 4 years, according to Rule 144 and lent the aggregate proceeds of
approximately $201,795 directly to us. The loans were evidenced by interest free
promissory notes, which were due, and payable on July 31, 1999. In July 1999,
Mr. Schwartz sold 500,000 shares of our common stock owned by him in excess of 4
years, according to Rule 144 and lent the aggregate proceeds of approximately
$137,241 directly to us. The loan was evidenced by interest free promissory
notes, which were due, and payable on August 31, 1999. All of these loans were
interest free and were evidenced by promissory notes. The May, June and July
promissory notes were due on June 30, 1999, July 31, 1999 and August 31, 1999,
respectively. The net proceeds were recorded as a loan payable to each
respective lender. Messrs. Grable and Schwartz received 390,000 and 925,500
shares of our restricted common stock, respectively, as payment in full for the
loans made between May 1999 and July 1999.

                         Sale of Unregistered Securities

Private Placement of Preferred Stock

We have had to rely on the private placement of preferred and common stock to
obtain working capital. In deciding to issue preferred stock pursuant to the
private placements, we took into account the number of common shares authorized
and outstanding, the market price of the common stock at the time of each
preferred sale and the number of common shares the preferred stock would have
been convertible into at the time of the sale. At the time of each private
placement of preferred stock there were enough shares, based on the price of our
common stock at the time of the sale of the preferred to satisfy the preferred
conversion requirements. Although our board of directors tried to negotiate a
floor on the conversion price of each series of preferred stock prior to sale,
it was unable to do so. In order to obtain working capital we will continue to
seek capital through debt or equity financing which may include the issuance of
convertible preferred stock whose rights and preferences are superior to those
of the common stock holders. We will endeavor to negotiate the best transaction
possible taking into account the impact on our shareholders, dilution, loss of
voting power and the possibility of a change-in-control. However, in order to
satisfy our working capital needs, we may be forced to issue convertible
securities and debentures with no limitations on conversion. In addition, the
dividends on the preferred stock affect the net losses applicable to
shareholders. There are also applicable adjustments as a result of the
calculation of the deemed preferred stock dividends because we have entered into
contracts providing for discounts on the preferred stock when it is converted.
As a result of the dividends on cumulative preferred stock, the net loss per
common shareholder has increased from $.07 per share for the fiscal year ending
June 30, 1998 to $.02 per share for the fiscal year ending June 30, 1999. The
cumulative total is $.21 per share.


In the event that we issue preferred stock without a limit on the number of
shares that can be issued upon conversion and the price of our common stock
decreases, the percentage of shares outstanding that will be held by preferred
holders upon conversion will increase accordingly. The lower the market price
the greater the number of shares to be issued to the preferred holders, upon
conversion, thus increasing the potential profits to the holders when the price
per share increases and the holders sell the common shares. In addition, the
sale of a substantial amount of preferred stock to relatively few holders could
cause a possible change-in-control. In the event of a voluntary or involuntary
liquidation while the preferred stock is outstanding, the holders will be
entitled to a preference in distribution of our property available for
distribution equal to $10,000 per share. The following table summarizes certain
information with regard to the Series B, C, D, E, F, G, H, and I preferred stock
as of February 28, 2000.

Series B Preferred Stock

In December 1996, Weyburn Overseas Limited and Goodland International Investment
Ltd. purchased the Series B preferred stock offering pursuant to Regulation D.
Net proceeds were used for working capital and the continuous research,
development and testing of our CTLM(TM). The conversion rate is 82% of the
average closing price over a five-day period prior to conversion.

On April 6, 1999, the Series B preferred stock was sold by the Series B
preferred holders to Charlton Avenue, LLC, an unaffiliated third party with no
prior relationship to us or the Series B preferred holders. On April 6, 1999, we
also entered into a subscription agreement with Charlton whereby we agreed to
issue to Charlton 138 shares of our Series I, 7% convertible preferred stock as
discussed below.

Series C Preferred Stock

On October 6, 1997, we finalized the private placement to Austost Anstalt
Schaan, UFH Endowment, Inc., Chris Baum, Avalon Capital Limited, Dominion
Capital, Ltd. and The Cuttyhunk Fund Limited, of our Series C convertible
preferred stock and warrants to purchase up to 105,000 shares of our common
stock at an exercise price of $1.63 per share and to purchase up to 50,000
warrants at an exercise price of $1.562 per share. These preferred shares were
convertible, at any time, commencing 45 days from the date of issuance and for a
period of 3 years thereafter, without additional consideration. The number of
fully paid and non-assessable shares of our common stock, no par value, issued
upon conversion was determined by dividing (i) the sum of $10,000 by (ii) the
conversion price in effect at the time of conversion. The conversion price was
equal to 75% of the average closing price of our common stock for the five-day
trading period ending on the day prior to the date of conversion; provided,
however, in no event was the conversion price to be greater than $1.222 per
share.

According to the Regulation S sale documents, we were also required to escrow an
aggregate of 3,435,583 shares of our common stock. The shares underlying the
preferred stock and warrants were entitled to demand registration rights in the
event that Regulation S was amended prior to the conversion of the preferred
stock. This right expired upon conversion.

These preferred shares were convertible, at any time, commencing 45 days from

additional consideration. The conversion price was equal to 75% of the average

The preferred shares pay a dividend of 6% per annum, payable in common stock at
the time of each conversion and were convertible, at any time, commencing May
15, 1998 and for a period of two years thereafter without additional
consideration. The number of fully paid and non-assessable shares of our common
stock, issued upon conversion was determined by dividing (i) the sum of $10,000
plus any earned dividends by (ii) the conversion price in effect at the time of
conversion. The conversion price is equal to 70% of the average closing price of
our common stock for the five-day trading period ending on the day prior to the

Series G Preferred Stock

On March 17, 1999, we finalized a private placement to Amro International, S.A.,
Nesher Inc., Hewlett Fund, and Guaranty & Finance Ltd., of our Series G
convertible preferred stock and two year warrants to purchase 65,625 shares of
our common stock at an exercise price of $.50 per share. Net proceeds of
$350,000 were used for working capital and the continuous research, development
and testing of the CTLM(TM).


The Series G convertible preferred stock has no dividend provisions. The number
of fully paid and non-assessable shares of common stock to be issued upon
conversion will be determined by dividing (i) the sum of $10,000 by (ii) the
conversion price in effect at the time of conversion. The conversion price is
equal to the lesser of (i) 75% discount to the two lowest bids in a ten-day
period immediately preceding the conversion date or (ii) $.54. There is no floor
on the conversion price and no time limits on conversion. The shares can be
converted at any time without additional consideration According to the terms of
the registration rights agreement we were required to register 100% of the
number of shares that would be required to be issued if the preferred stock were
converted on the day before the filing of the registration statement. In the
event that the registration statement was not filed within 14 days from the
closing or that it was not declared effective within 60 days, we are required to
pay the Series G preferred holders, as liquidated damages, for failure to have
the registration statement declared effective, not as a penalty, 3% of the
principal amount of the securities sold for each 30-day period thereafter until
we procure registration of the securities. In the event that the registration
statement is not declared effective within 120 days, the Series G preferred
holders have the right to force us to redeem the Series G preferred at a
redemption price of 120% of the face value of the preferred. According to the
registration rights agreement, 100% of that number of shares that would be
required to be issued if the Series G preferred were converted on the day before
the filing of the registration statement, 1,801,803, are being registered on
behalf of the holders.


Series H Preferred Stock

On June 2, 1998, we finalized a private placement to Austost Anstalt Schaan and
Balmore Funds S.A. of our Series H convertible preferred stock and 75,000 A
warrants and 50,000 B warrants. The A and B warrants are exercisable at $1.00
and $1.50 per share, respectively. Net proceeds of $990,000 were used for
working capital and the continuous research, development and testing of the
CTLM(TM).


The number of fully paid and non-assessable shares of common stock to be issued
upon conversion will be determined by dividing the (i) the sum of $10,000 by
(ii) the conversion price in effect at the time of conversion. The conversion
price is equal to the lesser of $.53 and 75% of the lowest closing bid price of
our common stock for the ten-day trading period ending on the day prior to the
date of conversion. There is no floor on the conversion price and no time limits
on conversion. The shares can be converted at any time without additional
consideration. According to the terms of the registration rights agreement, as
amended, we have registered herein 100% of that number of shares that would be
required to be issued if the preferred stock were converted on the day before
the filing of the registration statement, 3,038,020 shares. We are in technical
default of the registration rights agreement, which required the registration
statement to be declared effective by October 2, 1998. According to the
registration rights agreement, we are required to pay the Series H preferred
holders in cash or in stock, as liquidated damages for failure to have the
registration statement declared effective, not as a penalty, 2% of the principal
amount of the securities sold for first 30-day period, and 3% of the principal
amount of the securities for each 30-day period thereafter until we procure
registration of the securities. According to the registration rights agreement,
liquidated damages of $169,000 have accrued as of March 31, 1999. We are
presently unable to comply with the liquidated damage provision payment and no
assurances can be given that we will be able to do so in the future. On March
25, 1999, we issued 424,242 shares of restricted common stock with registration
rights to the Series H preferred shareholders in lieu of cash for liquidated
damages through March 2, 1999. The value of these shares was $140,000, leaving a
balance of $29,000 due for liquidated damages through March 31, 1999. We have
the option of paying the accrued dividends and liquidated damages in common
stock.

Series I Preferred

On April 6, 1999, we also entered into a subscription agreement with Charlton
where we agreed to issue Charlton 138 shares of our Series I, 7% convertible
preferred stock. Our board of directors established the value of the Series I
preferred at $10,000 per share. Consideration for the subscription was paid as
follows:

   (i)   payments of all of the accumulated dividends (approximately $725,795)
         in connection with the Series B preferred stock;
   (ii)  settlement and dismissal, with prejudice, of all litigation concerning
         the Series B preferred stock and the exchange of mutual releases;
   (iii) cancellation of 112,500 warrants that were issued with the Series B

   (iv)  amendment of the Series B designation to impose a limitation on the
         owner(s) of the Series B preferred stock to ownership of not more than
         4.99% of our outstanding common stock at any one time.

The Series I preferred pay a 7% premium, to be paid in cash or freely trading
common stock in our sole discretion, at the time of each conversion. The number
of fully paid and non-assessable shares of common stock to be issued upon
conversion will be determined by dividing (i) the sum of $10,000 by (ii) the
conversion price in effect at the time of conversion. The conversion price is
equal to 75% of the average closing price of our common stock for the five-day
trading period ending on the day prior to the date of the conversion.


According to the registration rights agreement, 100% of that number of shares
that would be required to be issued if the I preferred stock were converted on
the day before the filing of the registration statement, 5,947,763, are being
registered on behalf of the holders.

Private Placement of Convertible Debentures

We have also had to rely on the private placement of convertible debentures to
obtain working capital. In deciding to issue convertible debentures, the board
of directors took into account many of the same considerations it did when it
decided to issue preferred stock. The following table summarizes certain
information with regard to our outstanding convertible debentures as of February
28, 2000.

Convertible Debentures - Charlton

We also entered into a subscription agreement with Charlton, where Charlton
purchased a convertible debenture for $1,100,000. In addition, we may draw down
a second tranche in the amount of $825,000 anytime 30 days after the effective
date of the registration statement as long as we maintain an average closing bid
price of $.45 for the 10 trading days immediately prior to the date we request
the second tranche funding. We may draw down a third tranche in the amount of
$825,000 anytime 60 days after the effective date of the registration statement
as long as we maintain an average closing bid price of $.45 for the 10 trading
days immediately prior to the date we request the third tranche funding. When
concluded, assuming all the conditions set forth above are met, the proceeds
from the original debenture offering will be $2,750,000. We entered into an
additional subscription agreement with Charlton for tranches totaling $330,000.


The debentures are secured by a mortgage on our corporate office building. The
mortgage will be released after the registration statement covering the common
stock underlying the debentures has been declared effective and upon the earlier
of (a) the day we qualify for listing on AMEX or NASDAQ, as long as said listing
requirements are not being met through a reverse split of our common stock, and
(b) 180 days from the date we receive the third tranche funding, as described
above.

The number of fully paid and non-assessable shares of common stock, no par
value, to be issued upon conversion will be determined by dividing (i) the sum
of $10,000 by (ii) the conversion price in effect at the time of conversion. The
conversion price is equal to 75% of the average closing price of our common
stock for the five-day trading period ending on the day prior to the date of the
conversion. The debentures can be converted at any time without additional
consideration.

In the event of a voluntary or involuntary liquidation while any of the
debentures are outstanding the holders are entitled to a preference in
distribution of our property available for distribution equal to the debentures
then outstanding principal and interest and will be able to foreclose against
the mortgage.

The proceeds from the sale of the Charlton convertible debenture ($1,100,000)
and any subsequent tranches of $1,980,000 totaling $3,080,000 will be used for
clinical trials expenses and working capital. As of the date of the registration
statement, no portion of the convertible debentures have been converted.


Convertible Debenture - Spinneret

We entered into a subscription agreement with Spinneret, LTD., where Spinneret
purchased a convertible debenture for $51,000. The sum of $1,000 was paid upon
issuance of the debenture for legal fees. The sum of $50,000 was advanced as a
loan on July 12, 1999, and the debenture was issued in the principal amount of
$51,000 on August 11, 1999. The debenture is due on August 11, 2001.


The number of fully paid and non-assessable shares of common stock, no par
value, to be issued upon conversion will be determined by dividing (i) the sum
of $10,000 by (ii) the conversion price in effect at the time of conversion. The
conversion price is equal to 75% of the average closing price of our common
stock for the five-day trading period ending on the day prior to the date of the
conversion. The debenture can be converted at any time without additional
consideration.


The proceeds from the sale of the debenture will be used for working capital. As
of the date of this report no portion of the convertible debenture has been
converted.

                                 Dividend Policy

To date, we have not declared or paid any dividends with respect to our capital
stock, and the current policy of our board of directors is to retain any
earnings to provide for our growth. Consequently, no cash dividends are expected
to be paid on our common stock in the foreseeable future.

                            Selling Security Holders

The selling security holders consist of common stock holders, the Series B, G, H
and I preferred holders and the holder of the convertible debentures. The
registration statement is a part of the prospectus being filed. The shares
offered in this prospectus are based on the various registration rights in the

                                       31
<PAGE>

subscription agreement and registration rights agreements between the selling
security holders and us. We are unable to determine the exact number of shares
that will actually be sold according to this prospectus due to:

o    the ability of the selling security holders to determine when and whether
     they will sell any shares under this prospectus; and
o    the uncertainty as to how many of the warrants will be exercised and how
     many shares of common stock will be issued upon conversion of the
     convertible debenture and the Series B, G, H and I preferred stock.


The number of fully paid and non-assessable shares of common stock, no par
value, to be issued upon conversion of the convertible debenture and the
unconverted outstanding preferred stock will be determined by dividing (i) the
sum of $10,000 by (ii) the conversion price in effect at the time of conversion.
The conversion prices are as follows:

(i) Series B, 82% of the five-day average closing price;
(ii) Series I, 75% of the five-day average closing price; and
(iii) the debentures, 75% of the five-day average closing price.


Since the conversion price of each of the preferred shares is based on the
market price of our common stock prior to the date of conversion, the number of
shares subject to registration rights will increase if the market price of our
common stock decreases, and also will decrease if the market price increases.
See "Sale of Unregistered Securities-Financing/Equity Line of Credit.

The following table identifies each selling security holder based upon
information provided to us as of July 27, 1999, with respect to the shares
beneficially held by or acquirable by, each selling security holder, and the
shares of common stock beneficially owned by the selling security holders which
are not covered by this prospectus. No selling security holder or its
affiliates, except for Deborah O'Brien, have held any position, office, or other
material relationship with us. Ms. O'Brien is one of our employees and the niece
of Linda Grable. Ms. O'Brien's shares were issued as partial compensation for a
$115,000 loan to us.

                                 Use Of Proceeds


         The selling security holders are selling all of the shares covered by
this prospectus for their own accounts. Accordingly, we will not receive any
proceeds from the resale of the shares. We will receive proceeds from the
exercise of the warrants, but, to date, none of the warrants have been
exercised. However, if all the warrants of which we are registering the
underlying shares on this prospectus were exercised as of February 28, 2000, we
would receive approximately $732,724 in proceeds. We would use any of these net
proceeds from the sale of these warrants for general corporate purposes,
including working capital. We will bear all expenses relating to this
registration.


                              Plan Of Distribution

         The shares may be sold or distributed from time to time by the selling
security holders or by pledgees, donees or transferees of, or successors in
interest to, the selling security holders, directly to one or more purchasers
(including pledgees) or through brokers, dealers or underwriters who may act
solely as agents or may acquire shares as principals, at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices, at negotiated prices or at fixed prices, which may be changed. The
distribution of the shares may be effected in one or more of the following
methods:

o    ordinary brokers transactions, which may include long or short sales,

o    transactions  involving  cross  or block  trades  or  otherwise  on the OTC
     Bulletin Board,

o    purchases by brokers,  dealers or  underwriters  as principal and resale by
     such purchasers for their own accounts pursuant to this prospectus,

o    "at the market" to or through market makers or into an existing  market for
     the common stock,

o    in other ways not involving  market makers or established  trading markets,
     including direct sales to purchasers or sales effected through agents,

o    through  transactions  in  options,  swaps  or other  derivatives  (whether
     exchange listed or otherwise), or

o    any combination of the foregoing, or by any other legally available means.

In addition, the selling security holders may enter into hedging transactions
with broker-dealers who may engage in short sales of shares in the course of
hedging the positions they assume with the selling security holders. The selling
security holders may also enter into option or other transactions with
broker-dealers that require the delivery by such broker-dealers of the shares,
which shares may be resold thereafter pursuant to this prospectus.

                                       34
<PAGE>

Brokers, dealers, underwriters or agents participating in the distribution of
the shares may receive compensation in the form of discounts, concessions or
commissions from the selling security holders and/or the purchasers of shares
for whom such broker-dealers may act as agent or to whom they may sell as
principal, or both (which compensation as to a particular broker-dealer may be
in excess of customary commissions). The selling security holders and any
broker-dealers acting in connection with the sale of the shares hereunder may be
deemed to be underwriters within the meaning of Section 2(11) of the Securities
Act of 1933, and any commissions received by them and any profit realized by
them on the resale of shares as principals may be deemed underwriting
compensation under the Securities Act of 1933, as amended. Neither we nor the
selling security holders can presently estimate the amount of such compensation.
We know of no existing arrangements between the selling security holders and any
other security holders, broker, dealer, underwriter or agent relating to the
sale or distribution of the shares.


We will not receive any proceeds from the sale of the common shares pursuant to
this prospectus. We have agreed to bear the expenses of the registration of the
shares, including legal and accounting fees, and such expenses are estimated to
be $30,874.


We have informed the selling stockholders that certain anti-manipulative rules
contained in Regulation M under the Securities Exchange Act of 1934, as amended,
may apply to their sales in the and have informed them of the need for delivery
of copies of this prospectus.

The selling security holders may also use Rule 144 under the Securities Act, to
sell the shares if they meet the criteria and conform to the requirements of
such rule.

                            Description Of Securities


Our authorized capital stock consists of 102,000,000 shares of capital stock of
which 100,000,000 shares are common stock, no par value, and 2,000,000 shares
are preferred stock, no par value. As of February 28, 2000, there were issued
and outstanding 97,200,698 shares of common stock, 60 shares of Series B
convertible preferred stock and 123 shares of Series I convertible preferred
stock, options to purchase 3,932,193 shares of common stock and warrants to
purchase 1,058,125 shares of common stock. In addition, Charlton has subscribed
for $3,080,000 in convertible debentures, $3,080,000 of which have been issued
to date, and Spinneret has a convertible debenture convertible into $51,000 of
shares of our common stock.


Common Stock

Holders of the common stock are entitled to one vote for each share held in the
election of directors and in all other matters to be voted on by shareholders.
There is no cumulative voting in the election of directors. Holders of common
stock are entitled to receive dividends as may be declared from time to time by
our board of directors out of funds legally available. In the event of
liquidation, dissolution or winding up, holders of common stock are to share in
all assets remaining after the payment of liabilities. The holders of common
stock have no preemptive or conversion rights and are not subject to further
calls or assessments. There are no redemption or sinking fund provisions
applicable to the common stock. The rights of the holders of the common stock
are subject to any rights that may be fixed for holders of preferred stock. All
of the outstanding shares of common stock are fully paid and non-assessable.

Preferred Stock

Our articles of incorporation authorize the issuance of preferred stock with
designations, rights, and preferences as may be determined from time to time by
the board of directors. The board of directors is empowered, without stockholder
approval, to designate and issue additional series of preferred stock with
dividend, liquidation, conversion, voting or other rights, including the right
to issue convertible securities with no limitations on conversion, which could
adversely affect the voting power or other rights of the holders of our common
stock, substantially dilute a common shareholder's interest and depress the
price of our common stock.

            Disclosure Of Commission Position On Indemnification For

                           Securities Act Liabilities

         Section 607.0850 of the Florida General Corporation Act allows
companies to indemnify their directors, officers and agent against expenses,
judgments, fines and amounts paid in settlement under that conditions and
limitations described in that law.

              Article VII of our Articles of Incorporation authorizes us to
              indemnify our directors and officers in the following manner:

o    To the extent  permitted by law,  none of our directors or officers will be
     personally  liable to us or our  shareholders for damages for breach of any
     duty  owed  by  the  directors  and  officers  to us or  our  shareholders;
     provided,  that, to the extent  required by law, the directors and officers
     will not be relieved  from  liability  for any breach of duty based upon an
     act or omission (i) in breach of such person's duty of loyalty to us or our
     shareholders,  (ii) not in good faith or  involving a knowing  violation of
     law or (iii)  resulting  in  receipt  by a  director  or an  officer  of an
     improper personal benefit. No amendment to or repeal of this Article and no
     amendment,  repeal or termination of  effectiveness  of any law authorizing
     this Article shall apply to or effect  adversely any right or protection of
     any of our  directors  or  officers  for or  with  respect  to any  acts or
     omissions of the directors or officers occurring prior to amendment, repeal
     or termination of effectiveness.

o    To the extent that any of our directors, officers or other corporate agents
     have been  successful on the merits or otherwise in defense of any civil or
     criminal  action,  suit, or proceeding  referred to above, or in defense of
     any claim,  issue,  or matter therein,  any director,  officer or corporate
     agent will be indemnified against any expenses (including  attorneys' fees)
     actually  and  reasonably  incurred by the  director,  officer or corporate
     agent in connection therewith.

o    Expenses  incurred  by a director,  officer,  or other  corporate  agent in
     connection with a civil or criminal action, suit, or proceeding may be paid
     by the Company in advance of the final  disposition  of the action suit, or
     proceeding  as  authorized  by our board of  directors  upon  receipt of an
     undertaking  by or on behalf of the corporate  agent to repay the amount if
     it shall  ultimately be determined that the director,  officer or corporate
     agent is not entitled to be  indemnified.  The officers and directors  have
     indemnification  agreements  and are  covered  by  Directors  and  Officers
     Liability Insurance in the amount of 1 million dollars.

     Insofar as indemnification  for liabilities  arising under the Securities
     Act of 1933 may be permitted to our directors,  officers and  controlling
     persons pursuant to these provisions,  or otherwise,  we have been advised
     that, in the  opinion of the SEC,  this type of  indemnification  is
     against  public policy as expressed in the Securities Act and is,
     therefore, unenforceable.

                                     Experts

Our audited financial statements incorporated by reference have been examined by
Margolies, Fink and Wichrowski, independent certified public accountants, for

For the purpose of this offering, Christopher S. Auguste, Esq., Parker Chapin
LLP, is our counsel in regard to this amendment to the registration statement.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

The Florida General Corporation Act permits a Florida corporation to indemnify a
present or former director or officer of the corporation (and certain other
persons serving at the request of the corporation in related capacities) for
liabilities, including legal expenses, arising by reason of service in such
capacity if such person shall have acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and in any criminal proceeding if such person had no reasonable
cause to believe his conduct was unlawful. However, in the case of actions
brought by or in the right of the corporation, no indemnification may be made
with respect to any matter as to which such director or officer shall have been
adjudged liable, except in certain limited circumstances.

Article VII of our Articles of Incorporation authorizes us to indemnify
directors and officers as follows:

         1. So long as permitted by law, no director of the corporation shall be
         personally liable to the corporation or its shareholders for damages
         for breach of any duty owed by such person to the corporation or its
         shareholders; provided, however, that, to the extent required by
         applicable law, this Article shall not relieve any person from
         liability for any breach of duty based upon an act or omission (i) in
         breach of such person's duty of loyalty to the corporation or its
         shareholders, (ii) not in good faith or involving a knowing violation
         of law or (iii) resulting in receipt by such person of an improper
         personal benefit. No amendment to or repeal of this Article and no
         amendment, repeal or termination of effectiveness of any law
         authorizing this Article shall apply to or effect adversely any right
         or protection of any director for or with respect to any acts or
         omissions of such director occurring prior to such amendment, repeal or
         termination of effectiveness.

         2. So long as permitted by law, no officer of the corporation shall be
         personally liable to the corporation or its shareholders for damages
         for breach of any duty owed by such person to the corporation or its
         shareholders; provided, however, that, to the extent required by
         applicable law, this Article shall not relieve any person from
         liability for any breach of duty based upon an act or omission (i) in
         breach of such person's duty of loyalty to the corporation or its
         shareholders, (ii) not in good faith or involving a knowing violation
         of law or (iii) resulting in receipt by such person of an improper
         personal benefit. No amendment to or repeal of this Article and no
         amendment, repeal or termination of effectiveness of any law
         authorizing this Article shall apply to or effect adversely any right
         or protection of any director for or with respect to any acts or
         omissions of such officer occurring prior to such amendment, repeal or
         termination of effectiveness.

         3. To the extent that a Director, Officer, or other corporate agent of
         this corporation has been successful on the merits or otherwise in
         defense of any civil or criminal action, suit, or proceeding referred
         to in sections (a) and (b), above, or in defense of any claim, issue,
         or matter therein, he shall be indemnified against any expenses
         (including attorneys' fees) actually and reasonably incurred by him in
         connection therewith.

         4. Expenses incurred by a Director, Officer, or other corporate agent
         in connection with a civil or criminal action, suit, or proceeding may
         be paid by the corporation in advance of the final disposition of such

                                      II-1
<PAGE>

         action suit, or proceeding as authorized by the Board of Directors upon
         receipt of an undertaking by or on behalf of the corporate agent to
         repay such amount if it shall ultimately be determined that he is not
         entitled to be indemnified.

INDEMNIFICATION FOR LIABILITIES UNDER THE SECURITIES ACT OF 1933 MAY BE
PERMITTED TO DIRECTORS, OFFICERS OR PERSONS CONTROLLING US ACCORDING TO THE
PROVISIONS IN OUR ARTICLES OF INCORPORATION, WE HAVE BEEN INFORMED THAT IN THE
OPINION OF THE SEC, THIS INDEMNIFICATION IS AGAINST PUBLIC POLICY AS EXPRESSED
IN THE ACT AND IS THEREFORE UNENFORCEABLE

ITEM 17.  UNDERTAKINGS.

         The undersigned registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

               (i)  To include any prospectus required by Section 10(a)(3) of
                    the Securities Act;

               (ii) To reflect in the prospectus any facts or events arising
                    after the effective date of the registration statement (or
                    the most recent post-effective amendment thereof) which,
                    individually or in the aggregate, represent a fundamental
                    change in the information set forth in the registration
                    statement. Notwithstanding the foregoing, any increase or
                    decrease in the volume of securities offered (if the total
                    dollar value of securities offered would not exceed that
                    which was registered) and any deviation from the low or high
                    and of the estimated maximum offering range may be reflected
                    in the form of prospectus filed with the Commission pursuant
                    to Rule 424 (b) if, in the aggregate the changes in volume
                    and price represent no more than 20 percent change in the
                    maximum aggregate offering price set forth in the
                    "Calculation of Registration Fee" table in the effective
                    registration statement.

               (iii) To include any material information with respect to the
                    plan of distribution not previously disclosed in the
                    registration statement or any material change to such
                    information in the registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof; and

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

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

                                      II-4
<PAGE>

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

                                      II-5

                                   SIGNATURES

According to the requirements of the Securities Act of 1933, as amended, the
Registrant certifies that it has reasonable grounds to believe that it meets the
requirement for filing on Form S-2 and has duly caused this Amended Registration
Statement to be signed on its behalf by the undersigned, thereunto duly
authorized, in the City of Plantation, State of Florida, on the 29th day of

6. PURCHASE OF EQUIPMENT.

     (a) Orders. Orders from Distributor for equipment shall be made by delivery
of a purchase order to IDSI. As soon as practicable after receipt of such
purchase order, IDSI will: (i) if such order is accepted, return to Distributor
IDSI's standard form of Sales Acknowledgment (the "Acknowledgment") setting
forth dates on which delivery will be made, or (ii) notify Distributor in
writing that such order is rejected. IDSI will use its best efforts to make
prompt delivery of the Equipment accepted by IDSI on the delivery dates
specified in the Acknowledgment, F.O.B. Fort Lauderdale, at the time and to the
entities and destinations listed in the purchase orders. IDSI shall not be
liable for any failure to deliver, if such failure has been occasioned by fire,
embargo, strike, failure to secure materials from a usual source of supply, or
any circumstance beyond IDSI's control, which shall prevent IDSI from making
deliveries in the normal course of its business. IDSI shall not, however, be
relieved from making delivery when the causes interfering with deliveries shall
have been removed. In particular, the Parties acknowledge that IDSI is reliant
on outside suppliers, which supply the components for its Equipment. Should
these suppliers fail to produce the required components in a timely manner, than
IDSI shall be excused from the delivery obligations under this Agreement until
such time as the components can be manufactured, delivered and installed in the
Equipment. In no event shall IDSI be responsible for any loss or liability
suffered by Distributor as a result of delay in delivery of any order. An order
could be rejected if the Distributor fails to meet the commitments of the
Agreement within the territory or otherwise acts inappropriately with respect to
distribution of the equipment.

     (b) Cancellation of Orders. Distributor may cancel any order (or any part
thereof) for Equipment by giving IDSI written notice of such cancellation at
least 91 days prior to the shipping date. If an order is cancelled, the charge
to the Distributor is 15% of the amount of the purchase order.

     (c) Rescheduling Orders. Distributor may at any time, upon not less than
thirty (30) days written notice to IDSI, reschedule and/or postpone the delivery
date relating to an order (or any part thereof) for up to thirty (30) days. The
postponement of delivery to a date more than thirty (30) days from the delivery
date specified in the initial order shall be deemed a cancellation of such
order. DISTRIBUTOR MAY NOT POSTPONE THE DELIVERY DATE MORE THAN ONCE WITH
RESPECT TO ANY ORDER. If Distributor cancels a previously rescheduled delivery
of Equipment, the applicable cancellation charges shall be based on the delivery
date specified in the initial order submitted by Distributor for such delivery.

acceptance of the order; provided, however, that if Distributor notifies IDSI in
writing prior to the effective date of such price increase that it quoted the
original price in an outstanding bid submitted prior to receipt of IDSI's
amended Price Lists, any order relating to such bid accepted by IDSI prior to
the effective date of such price increase for shipment within ninety (90) days
of such effective date will be billed at the prices in effect at the time of
acceptance. All other shipments after thirty (30) days (or ninety days, if
applicable) of such effective date shall be billed at the prices set forth in
the amended Price List.

     (c) Payment. All payments hereunder shall be in United States dollars and
shall be effected by means of confirmed, irrevocable letters of credit opened by

                        IMAGING DIAGNOSTIC SYSTEMS, INC.

     THIS  CERTIFIES  that,  for  value  received,  Cycle of Life  Technologies,
Inc.(the  "Investor/Lender"),  is  entitled,  upon the terms and  subject to the
conditions  hereinafter set forth, at any time on or after July 26, 2000, and on
or prior to July 25,  2002  (the  "Termination  Date")  but not  thereafter,  to
subscribe  for and purchase  from IMAGING  DIAGNOSTIC  SYSTEMS,  INC., a Florida
corporation  (the  "Company"),  one million  five hundred  thousand  (1,500,000)
shares of Common Stock (the "Warrant  Shares").  The purchase price of one share
of Common Stock (the  "Exercise  Price")  under this  Warrant  shall be equal to
$.35.  The  Exercise  Price and the  number of shares  for which the  Warrant is
exercisable  shall be subject to  adjustment  as  provided  herein.  The Warrant
cannot be exercised  into common  shares for 180 days from the date of execution
of this Common Stock  Purchase  Warrant.  The Exercise Price may be satisfied by
the  delivery  of the Note to the  Company.  This  Warrant  is being  issued  in
connection with a Promissory Note dated as of January 27, 2000, in the amount of
five hundred  thousand  ($500,000)  Dollars (the "Note") between the Company and
Investor/Lender  and is  subject  to its  terms.  In the  event of any  conflict
between the terms of this Warrant and the Note, the Note shall control.

     1.  Title of  Warrant.  Prior  to the  expiration  hereof  and  subject  to
compliance  with  applicable  laws,  this Warrant and all rights  hereunder  are
transferable, in whole or in part, at the office or agency of the Company by the
holder hereof in person or by duly authorized  attorney,  upon surrender of this
Warrant together with the Assignment Form annexed hereto properly endorsed.

     2. Authorization of Shares. The Company covenants that all shares of Common
Stock  which may be issued  upon the  exercise  of  rights  represented  by this
Warrant will, upon exercise of the rights  represented by this Warrant,  be duly
authorized,  validly  issued,  fully paid and  non-assessable  and free from all
taxes,  liens and charges in respect of the issue  thereof  (other than taxes in
<PAGE>

respect of any transfer occurring contemporaneously with such issue).

     3. Exercise of Warrant. Exercise of the purchase rights represented by this
Warrant may be made at any time or times, in whole, before the close of business
on the  Termination  Date,  or such  earlier  date on  which  this  Warrant  may
terminate as provided in paragraph  11 below,  by the  surrender of this Warrant
and the  Subscription  Form annexed hereto duly  executed,  at the office of the
Company (or such other  office or agency of the Company as it may  designate  by
notice in writing to the registered  holder hereof at the address of such holder
appearing on the books of the Company) and upon payment of the Exercise Price of
the shares  thereby  purchased;  whereupon  the holder of this Warrant  shall be
entitled to receive a  certificate  for the number of shares of Common  Stock so
purchased. Certificates for shares purchased hereunder shall be delivered to the
holder  hereof  within five  business  days after the date on which this Warrant
shall have been  exercised as  aforesaid.  Payment of the Exercise  Price of the
shares may be by a certified  check or cashier's check or by wire transfer to an
account  designated by the Company or by surrender of the Note or by a "cashless
exercise"  of the  Warrant in which  event the  Holder  shall  receive  from the
Company  the number of shares of common  stock equal (i) the number of shares as
to which this Warrant is being exercised, minus (ii) the number of shares having
an aggregate  value  (determined by the average  closing bid price of the Common
stock (as reported by Bloomberg,  LP) for the 20 consecutive  trading days prior
to the "cashless exercise") equal to the product of (x) the Exercise Price times
(y) the number of Warrant Shares as to which this Warrant is being exercised.

     4.  No  Fractional   Shares  or  Scrip.  No  fractional   shares  or  scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant.

     5. Charges,  Taxes and  Expenses.  Issuance of  certificates  for shares of
Common Stock upon the exercise of this Warrant  shall be made without  charge to
the holder hereof for any issue or transfer tax or other  incidental  expense in
respect of the  issuance of such  certificate,  all of which taxes and  expenses
shall be paid by the Company,  and such certificates shall be issued in the name
of the holder of this Warrant or in such name or names as may be directed by the
holder of this Warrant;  provided,  however,  that in the event certificates for
shares of Common  Stock  are to be issued in a name  other  than the name of the
holder of this  Warrant,  this Warrant when  surrendered  for exercise  shall be
accompanied by the Assignment  Form attached  hereto duly executed by the holder
hereof; and provided further, that upon any transfer involved in the issuance or
delivery  of any  certificates  for  shares of Common  Stock,  the  Company  may
require, as a condition thereto, the payment of a sum sufficient to reimburse it
for any transfer tax incidental thereto.

     6.  Closing of Books.  The  Company  will at no time close its  shareholder
books or records in any manner which interferes with the timely exercise of this
Warrant.

     7. No Rights as Shareholder  until Exercise.  This Warrant does not entitle
the holder hereof to any voting  rights or other rights as a shareholder  of the
Company prior to the exercise thereof. If, however, at the time of the surrender
of this  Warrant and  purchase  the holder  hereof shall be entitled to exercise
this  Warrant,  the shares so  purchased  shall be and be deemed to be issued to


<PAGE>

such  holder as the record  owner of such  shares as of the close of business on
the date on which this Warrant shall have been exercised.

     8. Assignment and Transfer of Warrant.  This Warrant may be assigned by the
surrender of this Warrant and the  Assignment  Form annexed hereto duly executed
at the office of the Company  (or such other  office or agency of the Company as
it may  designate by notice in writing to the  registered  holder  hereof at the
address  of such  holder  appearing  on the  books  of the  Company);  provided,
however, that this Warrant may not be resold or otherwise transferred except (i)
in a transaction  registered  under the Securities Act, or (ii) in a transaction
pursuant to an exemption, if available, from such registration

     9.  Loss,  Theft,   Destruction  or  Mutilation  of  Warrant.  The  Company
represents and warrants that upon receipt by the Company of evidence  reasonably
satisfactory to it of the loss, theft,  destruction or mutilation of any Warrant
or stock certificate, and in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it, and upon reimbursement to the Company of
all reasonable expenses incidental thereto,  and upon surrender and cancellation
of such Warrant or stock  certificate,  if mutilated,  the Company will make and
deliver a new  Warrant or stock  certificate  of like tenor and dated as of such
cancellation, in lieu of this Warrant or stock certificate.

     10. Saturdays, Sundays, Holidays, etc. If the last or appointed day for the
taking of any action or the  expiration of any right  required or granted herein
shall be a Saturday, Sunday or a legal holiday, then such action may be taken or
such right may be exercised on the next succeeding day not a legal holiday.

     11. Effect of Certain Events.

     (a) If at any time the Company proposes (i) to sell or otherwise convey all
or substantially all of its assets or (ii) to effect a transaction (by merger or
otherwise) in which more than 50% of the voting power of the Company is disposed
of (collectively, a "Sale or Merger Transaction"), in which the consideration to
be received  by the Company or its  shareholders  consists  solely of cash,  the
Company shall give the holder of this Warrant  thirty (30) days' written  notice
by certified mail of the proposed  effective date of the transaction  specifying
that the Warrant  shall  terminate if the Warrant has not been  exercised by the
effective date of the transaction.

     (b) In  case  the  Company  shall  at any  time  effect  a Sale  or  Merger
Transaction  in which the  consideration  to be  received  by the Company or its
shareholders  consists in part of  consideration  other than cash, the holder of
this Warrant shall have the right  thereafter  to purchase,  by exercise of this
Warrant and payment of the aggregate  Exercise Price in effect immediately prior
to such action,  the kind and amount of shares and other securities and property
which it would have owned or have been  entitled to receive  after the happening
of such transaction had this Warrant been exercised immediately prior thereto.

     (c) Registration. The Company agrees to register the shares of Common Stock
underlying  this  Warrant  pursuant  to the  terms  of  the  Agreement  and  the
<PAGE>

Registration  Rights  Agreement  dated  January  27,  2000.  In  addition to the
foregoing, the Holder of this Warrant shall have the right to include all of the
shares of Common Stock underlying this Warrant (the "Registrable Securities") as
part of any  registration  of  securities  filed by the  Company  (other than in
connection with a transaction  contemplated by Rule 145(a) promulgated under the
Act or pursuant  to Form S-8) and must be  notified  in writing of such  filing.
Holder shall have five (5) business  days to notify the Company in writing as to
whether  the Company is to include  Holder or not include  Holder as part of the
registration;  provided,  however,  that if any  registration  pursuant  to this
Section shall be underwritten, in whole or in part, the Company may require that
the Registrable  Securities  requested for inclusion pursuant to this Section be
included in the  underwriting on the same terms and conditions as the securities
otherwise being sold through the underwriters.  If in the good faith judgment of
the  underwriter  evidenced in writing of such offering only a limited number of
Registrable  Securities  should be included in such offering,  or no such shares
should be included,  the Holder,  and all other selling  stockholders,  shall be
limited to registering such proportion of their respective shares as shall equal
the proportion that the number of shares of selling stockholders permitted to be
registered by the  underwriter in such offering bears to the total number of all
shares then held by all selling  stockholders  desiring to  participate  in such
offering.  Those Registrable  Securities which are excluded from an underwritten
offering  pursuant to the  foregoing  provisions  of this Section (and all other
Registrable  Securities held by the selling stockholders) shall be withheld from
the market by the Holders thereof for a period, not to exceed one hundred eighty
(180) days, which the underwriter may reasonably determine is necessary in order
to effect such underwritten offering.

     12.  Adjustments of Exercise Price and Number of Warrant Shares. The number
and kind of  securities  purchasable  upon the  exercise of this Warrant and the
Exercise  Price  shall be  subject  to  adjustment  from  time to time  upon the
happening of any of the following.

     In case the Company shall (i) declare or pay a dividend in shares of Common
Stock or make a  distribution  in  shares  of  Common  Stock to  holders  of its
outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock,
(iii) combine its  outstanding  shares of Common Stock into a smaller  number of
shares of Common  Stock or (iv) issue any shares of its  capital  stock for less
than 35 cents per share or effect a  reclassification  of the Common Stock,  the
number of Warrant Shares  purchasable upon exercise of this Warrant  immediately
prior  thereto  shall be  adjusted so that the holder of this  Warrant  shall be
entitled to receive the kind and number of Warrant Shares or other securities of
the Company  which he would have owned or have been entitled to receive had such
Warrant been exercised in advance  thereof.  An adjustment made pursuant to this
paragraph shall become  effective  immediately  after the effective date of such
event retroactive to the record date, if any, for such event.

     13. Voluntary  Adjustment by the Company. The Company may at its option, at
any time during the term of this Warrant, reduce the then current Exchange Price
to any  amount  and for any period of time  deemed  appropriate  by the Board of
Directors of the Company.
<PAGE>

     14. Notice of  Adjustment.  Whenever the number of Warrant shares or number
or kind of securities or other  property  purchasable  upon the exercise of this
Warrant or the Exercise Price is adjusted, as herein provided, the Company shall
promptly mail by registered or certified mail, return receipt requested,  to the
holder of this Warrant notice of such  adjustment or  adjustments  setting forth
the number of Warrant Shares (and other securities or property) purchasable upon
the exercise of this Warrant and the Exercise Price of such Warrant Shares after
such  adjustment,  setting forth a brief  statement of the facts  requiring such
adjustment and setting forth computation by which such adjustment was made. Such
notice,  in absence of  manifest  error,  shall be  conclusive  evidence  of the
correctness of such adjustment.

     15.  Authorized  Shares.  The Company  covenants that during the period the
Warrant is outstanding,  it will reserve from its authorized and unissued Common
Stock a sufficient  number of shares to provide for the issuance of Common Stock
upon the exercise of any purchase  rights under this Warrant.  In the event that
the Company has insufficient  authorized and unissued Common Stock it shall seek
to  increase  its  authorized  shares  through  either a  written  action of the
majority of its  shareholders  or a shareholder's  meeting.  The Company further
covenants that its issuance of this Warrant shall  constitute  full authority to
its officers who are charged with the duty of executing  stock  certificates  to
execute and issue the necessary  certificates for shares of the Company's Common
Stock upon the exercise of the purchase  rights under this Warrant.  The Company
will take all such  reasonable  action as may be  necessary  to assure that such
shares of Common Stock may be issued as provided herein without violation of any
applicable law or regulation,  or of any  requirements of the OTC Bulletin Board
or any domestic securities exchange upon which the Common Stock may be listed.

     16. Miscellaneous.

     (a) Issue Date;  Jurisdiction.  The  provisions  of this  Warrant  shall be
construed and shall be given effect in all respects as if it had been issued and
delivered by the Company on the date hereof.  This Warrant shall be binding upon
any  successors  or assigns of the  Company.  This  Warrant  shall  constitute a
contract  under the laws of Florida and for all  purposes  shall be construed in
accordance  with and  governed by the laws of said state  without  regard to its
conflict of law, principles or rules. The party who initiates legal action shall
choose the  jurisdiction of the federal courts or the state courts in connection
with any dispute arising under this Agreement and hereby waives,  to the maximum
permitted by law, any  objection,  including  any  objection  based on forum non
conveniens,  to the bringing of any such proceeding in such jurisdictions.  Each
party waives its right to a trial by jury.

     (b)  Restrictions.  The holder  hereof  acknowledges  that the Common Stock
acquired  upon  the  exercise  of this  Warrant,  if not  registered,  may  have
restrictions upon its resale imposed by state and federal securities laws.

     (c) Modification and Waiver.  This Warrant and any provisions hereof may be
changed,  waived,  discharged  or  terminated  only by an  instrument in writing
signed by the party against which enforcement of the same is sought.
<PAGE>

     (d) Notices. Any notice, request or other document required or permitted to
be given or delivered to the holders hereof of the Company shall be delivered or
shall be sent by certified or registered  mail,  postage  prepaid,  to each such
holder at its  address as shown on the books of the Company or to the Company at
the address set forth in the Agreement.

     IN WITNESS  WHEREOF,  the Company has caused this Warrant to be executed by
its officers thereunto duly authorized.

          notice to the Company, may elect to deem the Executive's employment
          hereunder to have been terminated by the Company without cause under
          Section 5(a) hereof, in which event the Executive shall be entitled to
          the compensation payable pursuant to clauses (i)-(iii) of Section
          5(a).

               (e) Voluntary Termination. The Executive, on 30 days prior

          concludes he must devote a substantial amount of his time and energies
          to his family or other personal matter and not to his business
          activities so as to preclude his fulfilling his obligations under this
          Agreement. Upon any such termination, the Company will pay the
          Executive (i) his annual salary at such time pursuant to Section 3(a)
          through the date of such termination of employment; and (ii) any bonus
          which would have been payable through the date of termination pursuant
          to Section 3(b).

          provisions of Section 6(a) shall be in effect, the Executive, will not
          directly or indirectly, solicit employees of the Company for

          joint venture or other entity. For the purposes of this Agreement, the
          term "Employee " means any person, firm, corporation, partnership,
          association or other entity which the Company, or any of its
          affiliates, employed during the during the 24-month period prior to

               (d) No Payment. The Executive acknowledges and agrees that no

any such confidential information to any person, firm, corporation, association
or other entity for any reason or purpose whatsoever without the prior written
consent of the board of directors of the Company, unless such confidential

          jurisdiction referred to in Section 8(b) below, to enjoin the

          irreparable harm or lack of an adequate remedy at law. Nothing
          contained in this Section 8 shall be construed to prevent the Company
          from seeking such other remedy in arbitration in case of any breach of
          this Agreement by the Executive, as the Company may elect.

               (b) Any proceeding or action must be commenced in the federal
          courts, or in the absence of federal jurisdiction in state court, in

          all future action necessary to submit to the jurisdiction of such
          courts. The Executive and the Company irrevocably waive any objection
          that they now have or hereafter irrevocably waive any objection that
          they now have or hereafter may have to the laying of venue of any
          suit, action or proceeding brought in any such court and further
          irrevocably waive any claim that any such suit, action or proceeding
          brought in any such court has been brought in an inconvenient forum.
          Final judgment against the Executive or the Company in any such suit
          shall be conclusive and may be enforced in other jurisdictions by suit
          on the judgment, a certified or true copy or which shall be conclusive
<PAGE>

          evidence of the fact and the amount of any liability of the Executive
          or the Company therein described, or by appropriate proceedings under
          any applicable treaty or otherwise.

     9. Assignability. The rights and obligations of the Company under this
Agreement shall inure to the benefit of and be binding upon the successors and
assigns of the Company, provided that such successor or assign shall acquire all
or substantially all of the assets and business of the Company. The Executive's
obligations hereunder may not be assigned or alienated and any attempt to do so
by the Executive will be void.

<PAGE>

         10.      Severability.

               (a) The Executive expressly agrees that the character, duration
          and geographical scope of the provisions set forth in this Agreement
          are reasonable in light of the circumstances, as they exist on the
          date hereof. Should a decision, however, be made at a later date by a
          court of competent jurisdiction that the character, duration or
          geographical scope of such provisions is unreasonable, then it is the
          intention and the agreement of the Executive and the Company that this
          Agreement shall be construed by the court in such a manner as to
          impose only those restrictions on the Executive's conduct that are
          reasonable in the light of the circumstances and as are necessary to
          assure to the Company the benefits of this Agreement. If, in any
          judicial proceeding, a court shall refuse to enforce all of the
          separate covenants deemed included herein because taken together they
          are more extensive than necessary to assure to the Company the
          intended benefits of this Agreement, it is expressly understood and
          agreed by the parties hereto that the provisions of this Agreement
          that, if eliminated, would permit the remaining separate provisions to
          be enforced in such proceeding shall be deemed eliminated, for the
          purposes of such proceeding, from this Agreement.

               (b) If any provision of this Agreement otherwise is deemed to be
          invalid or unenforceable or is prohibited by the laws of the state or
          jurisdiction where it is to be performed, this Agreement shall be
          considered divisible as to such provision and such provision shall be
          inoperative in such state or jurisdiction and shall not be part of the
          consideration moving from either of the parties to the other. The
          remaining provisions of this Agreement shall be valid and binding and
          of like effect as though such provision were not included.

     11. Notices and Addresses. All notices, offers, acceptance and any other
acts under this Agreement (except payment) shall be in writing, and shall be
sufficiently given if delivered to the addressees in person, by Federal Express
or similar receipted delivery, by facsimile delivery or, if mailed, postage
prepaid, by certified mail, return receipt requested, as follows:

between the parties and supersedes all prior oral and written agreements between

                             STOCK OPTION AGREEMENT

     THIS STOCK OPTION AGREEMENT (the "Agreement") entered into as of the 30th
day of August 1999, between Imaging Diagnostic Systems, Inc. the "Company") and
Allan L. Schwartz, an Executive of the Company ("Executive").

     WHEREAS, by action taken by the board of directors of the Company on August
30, 1999, it has adopted a 1999 Equity Incentive Plan (the "Plan"); and

     WHEREAS, by action taken by the board of directors of the Company on the
same date, it has been determined that in order to enhance the ability of the
Company to attract and retain qualified officers it will grant Executive the
right to purchase stock in the Company pursuant to incentive options.

     NOW THEREFORE, in consideration of the mutual covenants and promises
hereafter set forth and for other good and valuable consideration, receipt of
which is acknowledged, the parties hereto agree as follows:

     1. Grant of Incentive Options. The Company irrevocably grants to Executive,
as a matter of separate agreement and not in lieu of salary or other
compensation for services, the right and option (the "Options") to purchase all
or any part of an aggregate of 2,500,000 shares of authorized but unissued
common stock of the Company or, at Executive's option, that number of Voting
Convertible Preferred Stock that would give Executive voting rights equal to the
2,500,000 shares of common stock, on the terms and conditions herein set forth.
The Options are intended to be Incentive Stock Options as defined by Section
422A of the Internal Revenue Code (the "Code").

     2. Price. The exercise price of the shares of common stock subject to the
Options shall be 110% of fair market value on the date of the grant ($.21 per
share).

     3. When Exercisable.

          (a) Provided that Executive is employed by the Company on the
     respective dates below, the Options shall vest as follows:

            Date                                     No. of Shares
            August 30, 1999                             500,000
            August 30, 2000                             500,000
            August 30, 2001                             500,000
            August 30, 2002                             500,000
            August 30, 2003                             500,000

          (b) Except as provided in paragraphs 2 and 3 of this Agreement, once
     any Option become exercisable they shall remain exercisable through August
     30, 2004.

          4. Conversion to Non-Qualified Options. In the event that the
     stockholders of the Company fail to approve the Plan within one year after
     approval by the Board of Directors, or in the event that the Executive is
     terminated with pursuant to Section 5 (a) or 5(d) of that certain
     Employment Agreement dated August 30, 1999 between the Company and the
     Executive, a copy of which, is on file at the Company's corporate office
     (the "Employment Agreement"), the exercise period for the Options shall be
     extended through August 30, 2009 thereby converting all of the Options to
     Non-Qualified Options. In such event, the Company shall pay Executive a
     tax-offset bonus each time he exercises any Options. The amount of the tax
     offset bonus shall be equal to the amount of federal income tax he incurs
     in connection with the exercise of the Options assuming he is at the
     highest marginal United States income bracket for the year of exercise.
     Such bonus shall be paid to Executive on or before February 1, of the year
     following exercise.
<PAGE>

     5. Termination of Relationship.

          (a) Except as set forth in Section 4 above, if for any reason, except
     death, Executive ceases to act as an employee of the Company, all rights
     granted hereunder shall terminate effective three months from the date
     Executive ceases to act as an employee.

          (b) If Executive shall die while an employee of the Company, his
     estate or any transferee, as defined herein, shall have the right within
     three months from the date of Executive's death to exercise Executive's
     Options to the extent the right to exercise to the Options shall have
     accrued at the date of death, except to the extent the Options shall have
     been exercised prior thereto. The exercise period for any Options not
     vested, shall be extended through August 30, 2004 thereby converting all of
     the Options to Non-Qualified Options. For the purpose of this Agreement,
     "transferee" shall mean a person to whom such shares are transferred by
     will or by the laws of descent and distribution.

          (c) No transfer of the Options by Executive by will or by the laws of
     descent and distribution shall be effective to bind the Company unless the
     Company shall have been furnished with written notice thereof and a copy of
     the letters testamentary or such other evidence as the board may deem
     necessary to establish the authority of the state and the acceptance by the
     transferee or transferees of the terms and conditions of the Options.

          (d) If Executive becomes disabled while employed by the Company within
     the meaning of Section 22(e)(3) of the Code, the three month period
     referred to in paragraph 3(a) of this Agreement shall be extended to one
     year.

     6. Method of Exercise/Registration. These Options shall be exercisable by a
     written notice, which shall:

          (a) state the election to exercise the Options, the number of shares
     to be exercised, the person in whose name the stock certificate or
     certificates for such shares of common stock is to be registered, his
     address and social security number (or if more than one, the names,
     addresses and social security numbers of such persons);

          (b) contain such representations and agreements as to the holder's
     investment intent with respect to such shares of common stock as set forth
     in paragraph 8 hereof;
<PAGE>

          (c) be signed by the person or persons entitled to exercise the
     Options and, if the Options is being exercised by any person or persons
     other than the Executive, be accompanied by proof, satisfactory to counsel
     for the Company, of the right of such person or persons to exercise the
     Options.

          (d) be accompanied by full payment of the purchase or exercise price
     there for either (i) in United States dollars in cash or by check; (ii) by
     Executive's personal recourse note bearing interest payable not less than
     annually at no less than 100% of the lowest applicable federal rate, as
     defined in Section 1274(d) of the Code; (iii) by having the Company retain
     a portion of the Shares covered by the option exercise, or (iv) by any
     combination of (i) (ii) and (iii) above.

     If the Executive chooses to pay the exercise price pursuant to (iii) above,
the number of Shares to be delivered to or withheld by the Company times the
fair market value shall equal the cash required for exercise. To the extent that
the Participant elects to either deliver or have withheld Shares of the
Company's Common Stock, the Board of Directors may require the Executive to make
such election only during certain periods of time as may be necessary to comply
with appropriate exemptive procedures regarding the "short-swing" profit
provisions of Section 16(b) of the Securities Exchange Act of 1934 or to meet
certain Internal Revenue Code requirements.

     The certificate or certificates for shares of common stock as to which the
Options shall be exercised shall be registered in the name of the person or
persons exercising the Options.

     The Company shall, if requested by the Executive, as expeditiously as
possible file a registration statement on a form of general use under the
Securities Act to permit the sale or other disposition of the Optioned Shares.
The Executive shall provide all information reasonable requested by the Company
for inclusion in any registration statement to be filed under this Agreement.
The Company will use its best efforts to cause such registration statement first
to become effective at the earliest practicable time and then to remain
effective for such period as the Executive reasonably deems necessary to effect
such sales or other dispositions or until all Optioned Shares no longer will
constitute "restricted securities" with the meaning of Rule 144 under the
Securities Act. Such registration shall be effected at the Company's expense
except for underwriting commissions and the fees and disbursements of the
Executive's counsel attributable to the registration of the Optioned Shares. The
Company and the Executive shall enter into an agreement under which each will
indemnify the other with respect to information provided by such party for use
in the registration statement, such indemnities and the procedures for them to
be in a form customarily included in registration rights agreements. The Company
further agrees to use its best efforts to register or qualify the Optioned Stock
covered under such registration statement under such other securities or
blue-sky laws of such jurisdictions as the Executive shall reasonably request.

     7. Reload Options. If the Executive pays all or a portion of the exercise
price of an Option or the tax required to be withheld pursuant to an exercise of
<PAGE>

an Option by surrendering shares of Stock pursuant to Section 6(d) above, the
Executive shall be automatically granted an Option for the purchase of Stock
equal to the number of shares surrendered (a "Reload Option"). The grant of the
Reload Option shall be effective on the date the Participant surrenders the
shares of Stock in respect of which the Reload Option is granted (the "Reload
Date"). The Reload Option shall have an exercise price equal to the Fair Market
Value of the Stock on the Reload Date, and shall have a term which is no longer,
and which shall lapse no later, than the original term of the underlying option.
If stock otherwise available under an Incentive Stock Option is withheld
pursuant to Section 6(d) above, any Reload Option granted in connection with the
withholding shall be treated as a new Incentive Stock Option, subject to the
rules set forth in the Plan..

     8. Adjustments. Upon the occurrence of any of the following events, the
Executive's rights with respect to Options granted hereunder shall be adjusted
as hereinafter provided unless otherwise specifically provided in the written
agreement between the Executive and the Company relating to such Option:

          (a) If the shares of Common Stock shall be subdivided or combined into
     a greater or smaller number of shares or if the Company shall issue any
     shares of Common Stock as a stock dividend on its outstanding Common Stock,
     the number of shares of Common Stock deliverable upon the exercise of
     Options shall be appropriately increased or decreased proportionately, and
     appropriate adjustments shall be made in the purchase price per share to
     reflect such subdivision, combination or stock dividend.

          (b) Except as provided for pursuant to Section 5 (a) or 5(d) of the
     Employment Agreement, if the Company is to be consolidated with or acquired
     by another entity in a merger, sale of all or substantially all of the
     Company's assets or otherwise (an "Acquisition"), the committee or the
     board of directors of any entity assuming the obligations of the Company
     hereunder (the "Successor Board") shall at the Executives sole option, as
     to outstanding Options, either (i) make appropriate provision for the
     continuation of such Options by substituting on an equitable basis for the
     shares then subject to such Options the consideration payable with respect
     to the outstanding shares of Common Stock in connection with the
     Acquisition; or (ii) terminate all Options in exchange for a cash payment
     equal to the excess of the fair market value of the shares subject to such
     Options (to the extent then exercisable) over the exercise price thereof.

          (c) In the event of a recapitalization or reorganization of the
     Company (other than a transaction described in subparagraph (b) above)
     pursuant to which securities of the Company or of another corporation are
     issued with respect to the outstanding shares of Common Stock, the
     Executive upon exercising an Option shall be entitled to receive for the
     purchase price paid upon such exercise the securities he would have
     received if he had exercised his Option prior to such recapitalization or
     reorganization.

          (d) Except as expressly provided herein, no issuance by the Company of
     shares of stock of any class or securities convertible into shares of stock
     of any class shall affect, and no adjustment by reason thereof shall be
     made with respect to, the number or price of shares subject to Options. No
     adjustments shall be made for dividends or other distributions paid in cash
     or in property other than securities of the Company.
<PAGE>

          (e) No fractional shares shall be issued pursuant to the Options, the
     Executive shall receive from the Company cash in lieu of such fractional
     shares.

          9. Necessity to Become Holder of Record. Neither the Executive nor his
     estate, as provided in paragraph 3(b), shall have any rights as a
     shareholder with respect to any shares covered by the Options until such
     person shall have become the holder of record of such shares. No adjustment
     shall be made for cash dividends or cash distributions, ordinary or
     extraordinary, in respect of such shares for which the record date is prior
     to the date on which he shall become the holder of record thereof.

          10. Reservation of Right to Terminate Relationship. Nothing contained
     in this Agreement shall restrict the right of the Company to terminate the
     relationship of Executive at any time, with or without cause. The
     termination of the relationship of Executive by the Company, regardless of
     the reason there for, shall have the results provided for in Section 5 of
     this Agreement.

          11. Conditions to Exercise of Options. In order to enable the Company
     to comply with the Securities Act of 1933 (the "Securities Act") and
     relevant state law, the Company shall require Executive, his estate, or any
     Transferee as a condition of the exercising of the Options granted
     hereunder, to give written assurance satisfactory to the Company that the
     shares subject to the Options are being acquired for his own account, for
     investment only, with no view to the distribution of same, and that any
     subsequent resale of any such shares either shall be made pursuant to a
     registration statement under the Securities Act and applicable state law
     which has become effective and is current with regard to the shares being
     sold, or shall be pursuant to an exemption from registration under the
     Securities Act and applicable state law.

          The Options are subject to the requirement that, if at any time the
     board of directors shall determine, in its discretion, that the listing,
     registration, or qualification of the shares of common stock subject to the
     Options upon any securities exchange or under any state or federal law, or
     the consent or approval of any governmental regulatory body, is necessary
     as a condition of, or in connection with the issue or purchase of shares
     under the Options, the options may not be exercised in whole or in part
     unless such listing, registration, qualification, consent or approval shall
     have been effected.

          12. Duties of Company. The Company will at all times during the term
     of Options:

               (a) Reserve and keep available for issue such number of shares of
          its authorized and unissued common stock as will be sufficient to
          satisfy the requirements of this Agreement;

               (b) Pay all original issue taxes with respect to the issue of
          shares pursuant hereto and all other fees and expenses necessarily
          incurred by the Company in connection therewith;

               (c) Use its best efforts to comply with all laws and regulations,
          which, in the opinion of counsel for the Company, shall be applicable
          thereto.

     13. Parties Bound by Plan. The Plan and each determination, interpretation

          this Agreement, the Company's Board of Directors, on a yearly basis,
          shall determine a bonus to be paid to Employee, based upon a
          percentage of the adjusted consolidated net earnings of the Company
          for each calendar year of Executive's employment, such sum to be
          computed as follows:

               (i) The adjusted consolidated net earnings of the Company shall

          independent accounting firm employed by the Company as its auditors,
          within 90 days after the end of each fiscal year.

               (ii) This computation of net earnings and of the Executive's
          percentage compensation, made in the manner here provided, shall be
          final and binding upon the Company and the Executive, and the Company
          shall pay such compensation to the Executive within 120 days after the
          end of the fiscal year in question. The Bonus may be paid in cash,
          stock, or options, by mutual agreement of the Executive and the
          Company.

               (iii) For purposes of computing the Executive's percentage
          compensation, the adjusted consolidated net earnings of the Company
          shall be determined after full allowance for, and deduction of the
          following: (a) all federal, state and municipal taxes; (b)
          depreciation for the period based on the amount of depreciation set
          forth in the annual report of the Company to its shareholders for the
          fiscal year which includes such period.

               (c) Expenses. In addition to any compensation received pursuant
          to Section 3(a), (b) and (c), the Company will reimburse or advance
          funds to the Executive for all reasonable travel, entertainment and
          miscellaneous expenses incurred in connection with the performance of
          his duties under this Agreement, provided that the Executive properly
          accounts for such expenses to the Company in accordance with the
          Company's practices. Such reimbursement or advances will be made in
          accordance with policies and procedures of the Company in effect from
          time to time relating to reimbursement of or advances to executive
          officers.

          Executive will be entitled to six weeks of vacation without loss of
          compensation or other benefits to which he is entitled under this

          the affairs of the Company may permit.

               (b) Employee Benefit Programs. Without limiting the compensation
          to which the Executive is entitled pursuant to the provisions of
          Section 3 or this Section 4, during the Term, the Executive will be
          entitled to participate in any pension, insurance or other employee
          benefit plan that is maintained at that time by the Company for its
          executive officers, including programs of life and medical insurance

               (c) Incentive Stock Options. The Executive shall receive

          date of such notice. Upon any such termination without cause:

                    (i) for the remainder of the term of this Agreement or for a
               period of 36 months following such termination, whichever is
               greater, the Company will continue to pay the Executive his
               annual salary pursuant to Section 3(a) and his Bonus pursuant to
               Section 3(b), and

                    (ii) the Company will continue to maintain for such period,
               for the benefit of the Executive, the employee benefit programs
               referred to in Section 4(b) that were in effect on the date of
               such termination.

               (b) Termination for Cause. The Company may terminate the
          Executive's employment pursuant to the terms of this Agreement at any
          time for cause by given written notice of termination. Such
          termination will become effective upon the giving of such notice,
          except that termination based upon clause (v) below shall not become
          effective unless the Executive shall fail to correct such breach
          within 30 days of receipt of written notice thereof provided pursuant
          to the preceding sentence. Upon any such termination for cause, the
          Executive shall have no right to compensation, commission, bonus or
          reimbursement under Section 3, or to participate in any employee
          benefit programs under Section 4 for any period subsequent to the
<PAGE>

          effective date of termination. For purposes of this Section 5(b),
          "cause" shall mean: (i) the Executive is convicted of a felony which
          is related to the Executive's employment or the business of the
          Company; (ii) the Executive, in carrying out his duties hereunder, has
          been found in a civil action by the Company, to have committed willful
          gross negligence or willful gross misconduct resulting, in either
          case, in material harm to the Company; (iii) the Executive
          misappropriates Company funds or otherwise defrauds the Company; (iv)
          the Executive materially breaches any provision of Section 6 or
          Section 7; and (v) the Executive materially fails to perform his
          duties under Section 2 resulting in material harm to the Company.

               (c) Death or Disability. Excepting for the conditions and
          obligations contained in this Section 5(c), this Agreement and the
          obligations of the Company hereunder will terminate upon the death or
          disability of the Executive. For purposes of this Section 5(c),
          "disability" shall mean that for a period of six months in any
          12-month period the Executive is incapable of substantially fulfilling
          the duties set forth in Section 2 because of physical, mental or
          emotional incapacity resulting from injury, sickness or disease.

         Upon termination by death or disability, the Company will pay the
         Executive or his legal representative, as the case may be: (i) his
         annual salary at such time pursuant to Section 3(a) through the date of
         such termination of employment; and (ii) the Executive's share of the
         Bonus as set forth in Section 3(b) of this Agreement. ;

               (d) Special Termination. In the event that (i) the Executive,
          with or without change in title or formal corporate action, shall no
          longer exercise all of the duties and responsibilities and shall no
          longer possess substantially all the authority set forth in Section 2;
          or (ii) the Company materially breaches this Agreement or the
          performance of its duties and obligations hereunder; or (iii) any
          entity or person not now an executive officer of the Company becomes
          either individually or as part of a group the beneficial owner of 20%
          or more of the Company's common stock, the Executive, by written
          notice to the Company, may elect to deem the Executive's employment
          hereunder to have been terminated by the Company without cause under
          Section 5(a) hereof, in which event the Executive shall be entitled to
          the compensation payable pursuant to clauses (i)-(iii) of Section
          5(a).

               (e) Voluntary Termination. The Executive, on 30 days prior
          written notice to the Company, may terminate his employment
          voluntarily (i) at any time following termination of the initial Term
          or (ii) at any time following the death or disabling illness of a
          member of the Executive's immediate family or similar personal,
          non-business related occurrence as a result of which the Executive
          concludes he must devote a substantial amount of his time and energies
          to his family or other personal matter and not to his business
          activities so as to preclude his fulfilling his obligations under this
          Agreement. Upon any such termination, the Company will pay the
          Executive (i) his annual salary at such time pursuant to Section 3(a)
          through the date of such termination of employment; and (ii) any bonus
          which would have been payable through the date of termination pursuant
          to Section 3(b).

               (f) Continuing Effect. Notwithstanding any termination of the
<PAGE>

          Executive's employment as provided in this Section 5 or otherwise, the
          provisions of Sections 6 and 7 shall remain in full force and effect.

6.       Non-competition Agreement.

               (a) Competition with the Company. Until termination of his
          employment and for a period of 12 months commencing on the date of
          termination, the Executive, directly or indirectly, in association
          with or as a stockholder, director, officer, consultant, employee,
          partner, joint venturer, member or otherwise of or through any person,
          firm, corporation, partnership, association or other entity, will not
          compete with the Company or any of its affiliates in the offer, sale
          or marketing of products or services that are competitive with the
          products or services offered by the Company, within any metropolitan
          area in the United States or elsewhere in which the Company is then
          engaged in the offer and sale of competitive products or services;
          provided, however, the foregoing shall not prevent Executive from
          accepting employment with an enterprise engaged in two or more lines
          of business, one of which is the same or similar to the Company's
          business (the "Prohibited Business") if Executive's employment is
          totally unrelated to the Prohibited Business; provided, further, the
          foregoing shall not prohibit Executive from owning up to 5% of the
          securities of any publicly-traded enterprise provided Executive is not
          an employee, director, officer, consultant to such enterprise or
          otherwise reimbursed for services rendered to such enterprise.

               (b) Solicitation of Customers. During the periods in which the
          provisions of Section 6(a) shall be in effect, the Executive, directly
          or indirectly, will not seek Prohibited Business from any Customer (as
          defined below) on behalf of any enterprise or business other than the
          Company, refer Prohibited Business from any Customer to any enterprise
          or business other than the Company or receive commissions based on
          sales or otherwise relating to the Prohibited Business from any
          Customer, or any enterprise or business other than the Company. For
          purposes of this Section 6(b), the term "Customer" means any person,
          firm, corporation, partnership, association or other entity to which
          the Company or any of its affiliates sold or provided goods or
          services during the 24-month period prior to the time at which any
          determination is required to be made as to whether any such person,
          firm, corporation, partnership, association or other entity is a
          Customer.

               (c) Solicitation of Employees. During the periods in which the
          provisions of Section 6(a) shall be in effect, the Executive, will not
          directly or indirectly, solicit employees of the Company for
          employment by any person, enterprise, business, company, partnership,
          joint venture or other entity. For the purposes of this Agreement, the
          term "Employee " means any person, firm, corporation, partnership,
          association or other entity which the Company, or any of its
          affiliates, employed during the during the 24-month period prior to
          the time at which any determination is required to be made as to
          whether any such person, firm, corporation, partnership, association
          or other entity is an Employee.

               (d) No Payment. The Executive acknowledges and agrees that no
          separate or additional payment will be required to be made to him in
          consideration of his undertakings in this Section 6.
<PAGE>

     7. Nondisclosure of Confidential Information. The Executive acknowledges
that during his employment he will learn and will have access to confidential
information regarding the Company and its affiliates, including without
limitation (i) confidential or secret plans, programs, documents, agreements or
other material relating to the business, services or activities of the Company
and its affiliates and (ii) trade secrets, market reports, customer
investigations, customer lists and other similar information that is proprietary
information of the Company or its affiliates (collectively referred to as
"confidential information"). The Executive acknowledges that such confidential
information as is acquired and used by the Company or its affiliates is a
special, valuable and unique asset. All records, files, materials and
confidential information obtained by the Executive in the course of his
employment with the Company are confidential and proprietary and shall remain
the exclusive property of the Company or its affiliates, as the case may be. The
Executive will not, except in connection with and as required by his performance
of his duties under this Agreement, for any reason use for his own benefit or
the benefit of any person or entity with which he may be associated or disclose
any such confidential information to any person, firm, corporation, association
or other entity for any reason or purpose whatsoever without the prior written
consent of the board of directors of the Company, unless such confidential
information previously shall have become public knowledge through no action by
or omission of the Executive.

         8.       Equitable Relief.

               (a) The Company and the Executive recognize that the services to
          be rendered under this Agreement by the Executive are special, unique
          and of extraordinary character, and that in the event of the breach by
          the Executive of the terms and conditions of this Agreement or if the
          Executive, without the prior consent of the board of directors of the
          Company, shall leave his employment for any reason and take any action
          in violation of Section 6 or Section 7, the Company will be entitled
          to institute and prosecute proceedings in any court of competent
          jurisdiction referred to in Section 8(b) below, to enjoin the
          Executive from breaching the provisions of Section 6 or Section 7. In
          such action, the Company will not be required to plead or prove
          irreparable harm or lack of an adequate remedy at law. Nothing
          contained in this Section 8 shall be construed to prevent the Company
          from seeking such other remedy in arbitration in case of any breach of
          this Agreement by the Executive, as the Company may elect.

               (b) Any proceeding or action must be commenced in the federal
          courts, or in the absence of federal jurisdiction in state court, in
          either case in Florida where the Company maintains its principal
          offices. The Executive and the Company irrevocably and unconditionally
          submit to the jurisdiction of such courts and agree to take any and
          all future action necessary to submit to the jurisdiction of such
          courts. The Executive and the Company irrevocably waive any objection
          that they now have or hereafter irrevocably waive any objection that
          they now have or hereafter may have to the laying of venue of any
          suit, action or proceeding brought in any such court and further
          irrevocably waive any claim that any such suit, action or proceeding
          brought in any such court has been brought in an inconvenient forum.
          Final judgment against the Executive or the Company in any such suit
          shall be conclusive and may be enforced in other jurisdictions by suit
          on the judgment, a certified or true copy or which shall be conclusive
<PAGE>

          evidence of the fact and the amount of any liability of the Executive
          or the Company therein described, or by appropriate proceedings under
          any applicable treaty or otherwise.

     9. Assignability. The rights and obligations of the Company under this
Agreement shall inure to the benefit of and be binding upon the successors and
assigns of the Company, provided that such successor or assign shall acquire all
or substantially all of the assets and business of the Company. The Executive's
obligations hereunder may not be assigned or alienated and any attempt to do so
by the Executive will be void.

<PAGE>

         10.      Severability.

               (a) The Executive expressly agrees that the character, duration
          and geographical scope of the provisions set forth in this Agreement
          are reasonable in light of the circumstances, as they exist on the
          date hereof. Should a decision, however, be made at a later date by a
          court of competent jurisdiction that the character, duration or
          geographical scope of such provisions is unreasonable, then it is the
          intention and the agreement of the Executive and the Company that this
          Agreement shall be construed by the court in such a manner as to
          impose only those restrictions on the Executive's conduct that are
          reasonable in the light of the circumstances and as are necessary to
          assure to the Company the benefits of this Agreement. If, in any
          judicial proceeding, a court shall refuse to enforce all of the
          separate covenants deemed included herein because taken together they
          are more extensive than necessary to assure to the Company the
          intended benefits of this Agreement, it is expressly understood and
          agreed by the parties hereto that the provisions of this Agreement
          that, if eliminated, would permit the remaining separate provisions to
          be enforced in such proceeding shall be deemed eliminated, for the
          purposes of such proceeding, from this Agreement.

               (b) If any provision of this Agreement otherwise is deemed to be
          invalid or unenforceable or is prohibited by the laws of the state or
          jurisdiction where it is to be performed, this Agreement shall be
          considered divisible as to such provision and such provision shall be
          inoperative in such state or jurisdiction and shall not be part of the
          consideration moving from either of the parties to the other. The
          remaining provisions of this Agreement shall be valid and binding and
          of like effect as though such provision were not included.

     11. Notices and Addresses. All notices, offers, acceptance and any other
acts under this Agreement (except payment) shall be in writing, and shall be
sufficiently given if delivered to the addressees in person, by Federal Express
or similar receipted delivery, by facsimile delivery or, if mailed, postage
prepaid, by certified mail, return receipt requested, as follows:

                             STOCK OPTION AGREEMENT

     THIS STOCK OPTION AGREEMENT (the "Agreement") entered into as of the 30th
day of August 1999, between Imaging Diagnostic Systems, Inc. the "Company") and
Linda B. Grable, an Executive of the Company ("Executive").

     WHEREAS, by action taken by the board of directors of the Company on August
30, 1999, it has adopted a 1999 Equity Incentive Plan (the "Plan"); and

     WHEREAS, by action taken by the board of directors of the Company on the
same date, it has been determined that in order to enhance the ability of the
Company to attract and retain qualified officers it will grant Executive the
right to purchase stock in the Company pursuant to incentive options.

     NOW THEREFORE, in consideration of the mutual covenants and promises
hereafter set forth and for other good and valuable consideration, receipt of
which is acknowledged, the parties hereto agree as follows:

     1. Grant of Incentive Options. The Company irrevocably grants to Executive,
as a matter of separate agreement and not in lieu of salary or other
compensation for services, the right and option (the "Options") to purchase all
or any part of an aggregate of 2,500,000 shares of authorized but unissued
common stock of the Company or, at Executive's option, that number of Voting
Convertible Preferred Stock that would give Executive voting rights equal to the
2,500,000 shares of common stock, on the terms and conditions herein set forth.
The Options are intended to be Incentive Stock Options as defined by Section
422A of the Internal Revenue Code (the "Code").

     2. Price. The exercise price of the shares of common stock subject to the
Options shall be 110% of fair market value on the date of the grant ($.21 per
share).

     3. When Exercisable.

          (a) Provided that Executive is employed by the Company on the
     respective dates below, the Options shall vest as follows:

            Date                                     No. of Shares
            August 30, 1999                             500,000
            August 30, 2000                             500,000
            August 30, 2001                             500,000
            August 30, 2002                             500,000
            August 30, 2003                             500,000

          (b) Except as provided in paragraphs 2 and 3 of this Agreement, once
     any Option become exercisable they shall remain exercisable through August
     30, 2004.

          4. Conversion to Non-Qualified Options. In the event that the
     stockholders of the Company fail to approve the Plan within one year after
     approval by the Board of Directors, or in the event that the Executive is
     terminated with pursuant to Section 5 (a) or 5(d) of that certain
     Employment Agreement dated August 30, 1999 between the Company and the
     Executive, a copy of which, is on file at the Company's corporate office
     (the "Employment Agreement"), the exercise period for the Options shall be
     extended through August 30, 2009 thereby converting all of the Options to
     Non-Qualified Options. In such event, the Company shall pay Executive a
     tax-offset bonus each time he exercises any Options. The amount of the tax
     offset bonus shall be equal to the amount of federal income tax he incurs
     in connection with the exercise of the Options assuming he is at the
     highest marginal United States income bracket for the year of exercise.
     Such bonus shall be paid to Executive on or before February 1, of the year
     following exercise.
<PAGE>

     5. Termination of Relationship.

          (a) Except as set forth in Section 4 above, if for any reason, except
     death, Executive ceases to act as an employee of the Company, all rights
     granted hereunder shall terminate effective three months from the date
     Executive ceases to act as an employee.

          (b) If Executive shall die while an employee of the Company, his
     estate or any transferee, as defined herein, shall have the right within
     three months from the date of Executive's death to exercise Executive's
     Options to the extent the right to exercise to the Options shall have
     accrued at the date of death, except to the extent the Options shall have
     been exercised prior thereto. The exercise period for any Options not
     vested, shall be extended through August 30, 2004 thereby converting all of
     the Options to Non-Qualified Options. For the purpose of this Agreement,
     "transferee" shall mean a person to whom such shares are transferred by
     will or by the laws of descent and distribution.

          (c) No transfer of the Options by Executive by will or by the laws of
     descent and distribution shall be effective to bind the Company unless the
     Company shall have been furnished with written notice thereof and a copy of
     the letters testamentary or such other evidence as the board may deem
     necessary to establish the authority of the state and the acceptance by the
     transferee or transferees of the terms and conditions of the Options.

          (d) If Executive becomes disabled while employed by the Company within
     the meaning of Section 22(e)(3) of the Code, the three month period
     referred to in paragraph 3(a) of this Agreement shall be extended to one
     year.

     6. Method of Exercise/Registration. These Options shall be exercisable by a
     written notice, which shall:

          (a) state the election to exercise the Options, the number of shares
     to be exercised, the person in whose name the stock certificate or
     certificates for such shares of common stock is to be registered, his
     address and social security number (or if more than one, the names,
     addresses and social security numbers of such persons);

          (b) contain such representations and agreements as to the holder's
     investment intent with respect to such shares of common stock as set forth
     in paragraph 8 hereof;
<PAGE>

          (c) be signed by the person or persons entitled to exercise the
     Options and, if the Options is being exercised by any person or persons
     other than the Executive, be accompanied by proof, satisfactory to counsel
     for the Company, of the right of such person or persons to exercise the
     Options.

          (d) be accompanied by full payment of the purchase or exercise price
     there for either (i) in United States dollars in cash or by check; (ii) by
     Executive's personal recourse note bearing interest payable not less than
     annually at no less than 100% of the lowest applicable federal rate, as
     defined in Section 1274(d) of the Code; (iii) by having the Company retain
     a portion of the Shares covered by the option exercise, or (iv) by any
     combination of (i) (ii) and (iii) above.

     If the Executive chooses to pay the exercise price pursuant to (iii) above,
the number of Shares to be delivered to or withheld by the Company times the
fair market value shall equal the cash required for exercise. To the extent that
the Participant elects to either deliver or have withheld Shares of the
Company's Common Stock, the Board of Directors may require the Executive to make
such election only during certain periods of time as may be necessary to comply
with appropriate exemptive procedures regarding the "short-swing" profit
provisions of Section 16(b) of the Securities Exchange Act of 1934 or to meet
certain Internal Revenue Code requirements.

     The certificate or certificates for shares of common stock as to which the
Options shall be exercised shall be registered in the name of the person or
persons exercising the Options.

     The Company shall, if requested by the Executive, as expeditiously as
possible file a registration statement on a form of general use under the
Securities Act to permit the sale or other disposition of the Optioned Shares.
The Executive shall provide all information reasonable requested by the Company
for inclusion in any registration statement to be filed under this Agreement.
The Company will use its best efforts to cause such registration statement first
to become effective at the earliest practicable time and then to remain
effective for such period as the Executive reasonably deems necessary to effect
such sales or other dispositions or until all Optioned Shares no longer will
constitute "restricted securities" with the meaning of Rule 144 under the
Securities Act. Such registration shall be effected at the Company's expense
except for underwriting commissions and the fees and disbursements of the
Executive's counsel attributable to the registration of the Optioned Shares. The
Company and the Executive shall enter into an agreement under which each will
indemnify the other with respect to information provided by such party for use
in the registration statement, such indemnities and the procedures for them to
be in a form customarily included in registration rights agreements. The Company
further agrees to use its best efforts to register or qualify the Optioned Stock
covered under such registration statement under such other securities or
blue-sky laws of such jurisdictions as the Executive shall reasonably request.

     7. Reload Options. If the Executive pays all or a portion of the exercise
price of an Option or the tax required to be withheld pursuant to an exercise of
<PAGE>

an Option by surrendering shares of Stock pursuant to Section 6(d) above, the
Executive shall be automatically granted an Option for the purchase of Stock
equal to the number of shares surrendered (a "Reload Option"). The grant of the
Reload Option shall be effective on the date the Participant surrenders the
shares of Stock in respect of which the Reload Option is granted (the "Reload
Date"). The Reload Option shall have an exercise price equal to the Fair Market
Value of the Stock on the Reload Date, and shall have a term which is no longer,
and which shall lapse no later, than the original term of the underlying option.
If stock otherwise available under an Incentive Stock Option is withheld
pursuant to Section 6(d) above, any Reload Option granted in connection with the
withholding shall be treated as a new Incentive Stock Option, subject to the
rules set forth in the Plan..

     8. Adjustments. Upon the occurrence of any of the following events, the
Executive's rights with respect to Options granted hereunder shall be adjusted
as hereinafter provided unless otherwise specifically provided in the written
agreement between the Executive and the Company relating to such Option:

          (a) If the shares of Common Stock shall be subdivided or combined into
     a greater or smaller number of shares or if the Company shall issue any
     shares of Common Stock as a stock dividend on its outstanding Common Stock,
     the number of shares of Common Stock deliverable upon the exercise of
     Options shall be appropriately increased or decreased proportionately, and
     appropriate adjustments shall be made in the purchase price per share to
     reflect such subdivision, combination or stock dividend.

          (b) Except as provided for pursuant to Section 5 (a) or 5(d) of the
     Employment Agreement, if the Company is to be consolidated with or acquired
     by another entity in a merger, sale of all or substantially all of the
     Company's assets or otherwise (an "Acquisition"), the committee or the
     board of directors of any entity assuming the obligations of the Company
     hereunder (the "Successor Board") shall at the Executives sole option, as
     to outstanding Options, either (i) make appropriate provision for the
     continuation of such Options by substituting on an equitable basis for the
     shares then subject to such Options the consideration payable with respect
     to the outstanding shares of Common Stock in connection with the
     Acquisition; or (ii) terminate all Options in exchange for a cash payment
     equal to the excess of the fair market value of the shares subject to such
     Options (to the extent then exercisable) over the exercise price thereof.

          (c) In the event of a recapitalization or reorganization of the
     Company (other than a transaction described in subparagraph (b) above)
     pursuant to which securities of the Company or of another corporation are
     issued with respect to the outstanding shares of Common Stock, the
     Executive upon exercising an Option shall be entitled to receive for the
     purchase price paid upon such exercise the securities he would have
     received if he had exercised his Option prior to such recapitalization or
     reorganization.

          (d) Except as expressly provided herein, no issuance by the Company of
     shares of stock of any class or securities convertible into shares of stock
     of any class shall affect, and no adjustment by reason thereof shall be
     made with respect to, the number or price of shares subject to Options. No
     adjustments shall be made for dividends or other distributions paid in cash
     or in property other than securities of the Company.
<PAGE>

          (e) No fractional shares shall be issued pursuant to the Options, the
     Executive shall receive from the Company cash in lieu of such fractional
     shares.

          9. Necessity to Become Holder of Record. Neither the Executive nor his
     estate, as provided in paragraph 3(b), shall have any rights as a
     shareholder with respect to any shares covered by the Options until such
     person shall have become the holder of record of such shares. No adjustment
     shall be made for cash dividends or cash distributions, ordinary or
     extraordinary, in respect of such shares for which the record date is prior
     to the date on which he shall become the holder of record thereof.

          10. Reservation of Right to Terminate Relationship. Nothing contained
     in this Agreement shall restrict the right of the Company to terminate the
     relationship of Executive at any time, with or without cause. The
     termination of the relationship of Executive by the Company, regardless of
     the reason there for, shall have the results provided for in Section 5 of
     this Agreement.

          11. Conditions to Exercise of Options. In order to enable the Company
     to comply with the Securities Act of 1933 (the "Securities Act") and
     relevant state law, the Company shall require Executive, his estate, or any
     Transferee as a condition of the exercising of the Options granted
     hereunder, to give written assurance satisfactory to the Company that the
     shares subject to the Options are being acquired for his own account, for
     investment only, with no view to the distribution of same, and that any
     subsequent resale of any such shares either shall be made pursuant to a
     registration statement under the Securities Act and applicable state law
     which has become effective and is current with regard to the shares being
     sold, or shall be pursuant to an exemption from registration under the
     Securities Act and applicable state law.

          The Options are subject to the requirement that, if at any time the
     board of directors shall determine, in its discretion, that the listing,
     registration, or qualification of the shares of common stock subject to the
     Options upon any securities exchange or under any state or federal law, or
     the consent or approval of any governmental regulatory body, is necessary
     as a condition of, or in connection with the issue or purchase of shares
     under the Options, the options may not be exercised in whole or in part
     unless such listing, registration, qualification, consent or approval shall
     have been effected.

          12. Duties of Company. The Company will at all times during the term
     of Options:

               (a) Reserve and keep available for issue such number of shares of

          published by the Bureau of Labor Statistics (or similar successor
          index) for the region in which the Executive resides, but in no event
          shall the cost of living increase be less than 7% per annum. The
          annual salary under this Section 3(a) will be reduced, however, to the
          extent that the Executive elects to defer any portion thereof under
          the terms of any deferred compensation or savings plan maintained by
          the Company. The Company will pay the Executive his annual salary in
          equal installments no less frequently than twice a month.

               (b) Bonus. For the services to be rendered by the Executive under
          this Agreement, the Company's Board of Directors, on a yearly basis,
          shall determine a bonus to be paid to Employee, based upon a
          percentage of the adjusted consolidated net earnings of the Company
          for each calendar year of Executive's employment, such sum to be
          computed as follows:

               (i) The adjusted consolidated net earnings of the Company shall
          be determined in accordance with accepted accounting practice by the
          independent accounting firm employed by the Company as its auditors,
          within 90 days after the end of each fiscal year.

               (ii) This computation of net earnings and of the Executive's
          percentage compensation, made in the manner here provided, shall be
          final and binding upon the Company and the Executive, and the Company
          shall pay such compensation to the Executive within 120 days after the
          end of the fiscal year in question. The Bonus may be paid in cash,
          stock, or options, by mutual agreement of the Executive and the
          Company.

               (iii) For purposes of computing the Executive's percentage
          compensation, the adjusted consolidated net earnings of the Company
          shall be determined after full allowance for, and deduction of the
          following: (a) all federal, state and municipal taxes; (b)
          depreciation for the period based on the amount of depreciation set
          forth in the annual report of the Company to its shareholders for the
          fiscal year which includes such period.

               (c) Expenses. In addition to any compensation received pursuant
          to Section 3(a), (b) and (c), the Company will reimburse or advance
          funds to the Executive for all reasonable travel, entertainment and
          miscellaneous expenses incurred in connection with the performance of
          his duties under this Agreement, provided that the Executive properly
          accounts for such expenses to the Company in accordance with the
          Company's practices. Such reimbursement or advances will be made in
          accordance with policies and procedures of the Company in effect from
          time to time relating to reimbursement of or advances to executive
          officers.

               4. Benefits.

               (a) Vacation. For each 12-month period during the Term, the
          Executive will be entitled to six weeks of vacation without loss of
          compensation or other benefits to which he is entitled under this
          Agreement, to be taken at such times as the Executive may select and
          the affairs of the Company may permit.

               (b) Employee Benefit Programs. Without limiting the compensation
          to which the Executive is entitled pursuant to the provisions of
          Section 3 or this Section 4, during the Term, the Executive will be
          entitled to participate in any pension, insurance or other employee
          benefit plan that is maintained at that time by the Company for its
          executive officers, including programs of life and medical insurance
          and reimbursement of membership fees in civic, social and professional
          organizations.

               (c) Incentive Stock Options. The Executive shall receive
          incentive options to purchase up to an aggregate of 2,500,000 shares

               (d) Miscellaneous Benefits. The Company shall also provide
          Executive with the following: (a) a $500 per month automobile

          date of such notice. Upon any such termination without cause:

                    (i) for the remainder of the term of this Agreement or for a
               period of 36 months following such termination, whichever is
               greater, the Company will continue to pay the Executive his
               annual salary pursuant to Section 3(a) and his Bonus pursuant to
               Section 3(b), and

                    (ii) the Company will continue to maintain for such period,
               for the benefit of the Executive, the employee benefit programs
               referred to in Section 4(b) that were in effect on the date of
               such termination.

               (b) Termination for Cause. The Company may terminate the
          Executive's employment pursuant to the terms of this Agreement at any
          time for cause by given written notice of termination. Such
          termination will become effective upon the giving of such notice,
          except that termination based upon clause (v) below shall not become
          effective unless the Executive shall fail to correct such breach
          within 30 days of receipt of written notice thereof provided pursuant
          to the preceding sentence. Upon any such termination for cause, the
          Executive shall have no right to compensation, commission, bonus or
          reimbursement under Section 3, or to participate in any employee
          benefit programs under Section 4 for any period subsequent to the
<PAGE>

          effective date of termination. For purposes of this Section 5(b),
          "cause" shall mean: (i) the Executive is convicted of a felony which
          is related to the Executive's employment or the business of the
          Company; (ii) the Executive, in carrying out his duties hereunder, has
          been found in a civil action by the Company, to have committed willful
          gross negligence or willful gross misconduct resulting, in either
          case, in material harm to the Company; (iii) the Executive
          misappropriates Company funds or otherwise defrauds the Company; (iv)
          the Executive materially breaches any provision of Section 6 or
          Section 7; and (v) the Executive materially fails to perform his
          duties under Section 2 resulting in material harm to the Company.

               (c) Death or Disability. Excepting for the conditions and
          obligations contained in this Section 5(c), this Agreement and the
          obligations of the Company hereunder will terminate upon the death or
          disability of the Executive. For purposes of this Section 5(c),
          "disability" shall mean that for a period of six months in any
          12-month period the Executive is incapable of substantially fulfilling
          the duties set forth in Section 2 because of physical, mental or
          emotional incapacity resulting from injury, sickness or disease.

         Upon termination by death or disability, the Company will pay the
         Executive or his legal representative, as the case may be: (i) his
         annual salary at such time pursuant to Section 3(a) through the date of
         such termination of employment; and (ii) the Executive's share of the
         Bonus as set forth in Section 3(b) of this Agreement. ;

               (d) Special Termination. In the event that (i) the Executive,
          with or without change in title or formal corporate action, shall no
          longer exercise all of the duties and responsibilities and shall no
          longer possess substantially all the authority set forth in Section 2;
          or (ii) the Company materially breaches this Agreement or the
          performance of its duties and obligations hereunder; or (iii) any
          entity or person not now an executive officer of the Company becomes
          either individually or as part of a group the beneficial owner of 20%
          or more of the Company's common stock, the Executive, by written
          notice to the Company, may elect to deem the Executive's employment
          hereunder to have been terminated by the Company without cause under
          Section 5(a) hereof, in which event the Executive shall be entitled to
          the compensation payable pursuant to clauses (i)-(iii) of Section
          5(a).

               (e) Voluntary Termination. The Executive, on 30 days prior
          written notice to the Company, may terminate his employment
          voluntarily (i) at any time following termination of the initial Term
          or (ii) at any time following the death or disabling illness of a
          member of the Executive's immediate family or similar personal,
          non-business related occurrence as a result of which the Executive
          concludes he must devote a substantial amount of his time and energies
          to his family or other personal matter and not to his business
          activities so as to preclude his fulfilling his obligations under this
          Agreement. Upon any such termination, the Company will pay the
          Executive (i) his annual salary at such time pursuant to Section 3(a)
          through the date of such termination of employment; and (ii) any bonus
          which would have been payable through the date of termination pursuant
          to Section 3(b).

               (f) Continuing Effect. Notwithstanding any termination of the
<PAGE>

          Executive's employment as provided in this Section 5 or otherwise, the
          provisions of Sections 6 and 7 shall remain in full force and effect.

6.       Non-competition Agreement.

               (a) Competition with the Company. Until termination of his
          employment and for a period of 12 months commencing on the date of
          termination, the Executive, directly or indirectly, in association
          with or as a stockholder, director, officer, consultant, employee,
          partner, joint venturer, member or otherwise of or through any person,
          firm, corporation, partnership, association or other entity, will not
          compete with the Company or any of its affiliates in the offer, sale
          or marketing of products or services that are competitive with the
          products or services offered by the Company, within any metropolitan
          area in the United States or elsewhere in which the Company is then
          engaged in the offer and sale of competitive products or services;
          provided, however, the foregoing shall not prevent Executive from
          accepting employment with an enterprise engaged in two or more lines
          of business, one of which is the same or similar to the Company's
          business (the "Prohibited Business") if Executive's employment is
          totally unrelated to the Prohibited Business; provided, further, the
          foregoing shall not prohibit Executive from owning up to 5% of the
          securities of any publicly-traded enterprise provided Executive is not
          an employee, director, officer, consultant to such enterprise or
          otherwise reimbursed for services rendered to such enterprise.

               (b) Solicitation of Customers. During the periods in which the
          provisions of Section 6(a) shall be in effect, the Executive, directly
          or indirectly, will not seek Prohibited Business from any Customer (as
          defined below) on behalf of any enterprise or business other than the
          Company, refer Prohibited Business from any Customer to any enterprise
          or business other than the Company or receive commissions based on
          sales or otherwise relating to the Prohibited Business from any
          Customer, or any enterprise or business other than the Company. For
          purposes of this Section 6(b), the term "Customer" means any person,
          firm, corporation, partnership, association or other entity to which
          the Company or any of its affiliates sold or provided goods or
          services during the 24-month period prior to the time at which any
          determination is required to be made as to whether any such person,
          firm, corporation, partnership, association or other entity is a
          Customer.

               (c) Solicitation of Employees. During the periods in which the
          provisions of Section 6(a) shall be in effect, the Executive, will not
          directly or indirectly, solicit employees of the Company for
          employment by any person, enterprise, business, company, partnership,
          joint venture or other entity. For the purposes of this Agreement, the
          term "Employee " means any person, firm, corporation, partnership,
          association or other entity which the Company, or any of its
          affiliates, employed during the during the 24-month period prior to
          the time at which any determination is required to be made as to
          whether any such person, firm, corporation, partnership, association
          or other entity is an Employee.

               (d) No Payment. The Executive acknowledges and agrees that no
          separate or additional payment will be required to be made to him in
          consideration of his undertakings in this Section 6.
<PAGE>

     7. Nondisclosure of Confidential Information. The Executive acknowledges
that during his employment he will learn and will have access to confidential
information regarding the Company and its affiliates, including without
limitation (i) confidential or secret plans, programs, documents, agreements or
other material relating to the business, services or activities of the Company
and its affiliates and (ii) trade secrets, market reports, customer
investigations, customer lists and other similar information that is proprietary
information of the Company or its affiliates (collectively referred to as
"confidential information"). The Executive acknowledges that such confidential
information as is acquired and used by the Company or its affiliates is a
special, valuable and unique asset. All records, files, materials and
confidential information obtained by the Executive in the course of his
employment with the Company are confidential and proprietary and shall remain
the exclusive property of the Company or its affiliates, as the case may be. The
Executive will not, except in connection with and as required by his performance
of his duties under this Agreement, for any reason use for his own benefit or
the benefit of any person or entity with which he may be associated or disclose
any such confidential information to any person, firm, corporation, association
or other entity for any reason or purpose whatsoever without the prior written
consent of the board of directors of the Company, unless such confidential
information previously shall have become public knowledge through no action by
or omission of the Executive.

         8.       Equitable Relief.

               (a) The Company and the Executive recognize that the services to
          be rendered under this Agreement by the Executive are special, unique
          and of extraordinary character, and that in the event of the breach by
          the Executive of the terms and conditions of this Agreement or if the
          Executive, without the prior consent of the board of directors of the
          Company, shall leave his employment for any reason and take any action
          in violation of Section 6 or Section 7, the Company will be entitled
          to institute and prosecute proceedings in any court of competent
          jurisdiction referred to in Section 8(b) below, to enjoin the
          Executive from breaching the provisions of Section 6 or Section 7. In
          such action, the Company will not be required to plead or prove
          irreparable harm or lack of an adequate remedy at law. Nothing
          contained in this Section 8 shall be construed to prevent the Company
          from seeking such other remedy in arbitration in case of any breach of
          this Agreement by the Executive, as the Company may elect.

               (b) Any proceeding or action must be commenced in the federal
          courts, or in the absence of federal jurisdiction in state court, in
          either case in Florida where the Company maintains its principal
          offices. The Executive and the Company irrevocably and unconditionally
          submit to the jurisdiction of such courts and agree to take any and
          all future action necessary to submit to the jurisdiction of such
          courts. The Executive and the Company irrevocably waive any objection
          that they now have or hereafter irrevocably waive any objection that
          they now have or hereafter may have to the laying of venue of any
          suit, action or proceeding brought in any such court and further
          irrevocably waive any claim that any such suit, action or proceeding
          brought in any such court has been brought in an inconvenient forum.
          Final judgment against the Executive or the Company in any such suit
          shall be conclusive and may be enforced in other jurisdictions by suit
          on the judgment, a certified or true copy or which shall be conclusive
<PAGE>

          evidence of the fact and the amount of any liability of the Executive
          or the Company therein described, or by appropriate proceedings under
          any applicable treaty or otherwise.

     9. Assignability. The rights and obligations of the Company under this
Agreement shall inure to the benefit of and be binding upon the successors and
assigns of the Company, provided that such successor or assign shall acquire all
or substantially all of the assets and business of the Company. The Executive's
obligations hereunder may not be assigned or alienated and any attempt to do so
by the Executive will be void.

<PAGE>

         10.      Severability.

               (a) The Executive expressly agrees that the character, duration
          and geographical scope of the provisions set forth in this Agreement
          are reasonable in light of the circumstances, as they exist on the
          date hereof. Should a decision, however, be made at a later date by a
          court of competent jurisdiction that the character, duration or
          geographical scope of such provisions is unreasonable, then it is the
          intention and the agreement of the Executive and the Company that this
          Agreement shall be construed by the court in such a manner as to
          impose only those restrictions on the Executive's conduct that are
          reasonable in the light of the circumstances and as are necessary to
          assure to the Company the benefits of this Agreement. If, in any
          judicial proceeding, a court shall refuse to enforce all of the
          separate covenants deemed included herein because taken together they
          are more extensive than necessary to assure to the Company the
          intended benefits of this Agreement, it is expressly understood and
          agreed by the parties hereto that the provisions of this Agreement
          that, if eliminated, would permit the remaining separate provisions to
          be enforced in such proceeding shall be deemed eliminated, for the
          purposes of such proceeding, from this Agreement.

               (b) If any provision of this Agreement otherwise is deemed to be
          invalid or unenforceable or is prohibited by the laws of the state or
          jurisdiction where it is to be performed, this Agreement shall be
          considered divisible as to such provision and such provision shall be
          inoperative in such state or jurisdiction and shall not be part of the
          consideration moving from either of the parties to the other. The
          remaining provisions of this Agreement shall be valid and binding and
          of like effect as though such provision were not included.

     11. Notices and Addresses. All notices, offers, acceptance and any other
acts under this Agreement (except payment) shall be in writing, and shall be
sufficiently given if delivered to the addressees in person, by Federal Express
or similar receipted delivery, by facsimile delivery or, if mailed, postage
prepaid, by certified mail, return receipt requested, as follows:

between the parties and supersedes all prior oral and written agreements between

terminated orally, except by a statement in writing signed by the party or
parties against which enforcement or the change, waiver discharge or termination
is sought.

     17. Additional Documents. The parties hereto shall execute such additional
instruments as may be reasonably required by their counsel in order to carry out

as a matter of separate agreement and not in lieu of salary or other
compensation for services, the right and option (the "Options") to purchase all
or any part of an aggregate of 2,500,000 shares of authorized but unissued
common stock of the Company or, at Executive's option, that number of Voting
Convertible Preferred Stock that would give Executive voting rights equal to the
2,500,000 shares of common stock, on the terms and conditions herein set forth.
The Options are intended to be Incentive Stock Options as defined by Section
422A of the Internal Revenue Code (the "Code").

     2. Price. The exercise price of the shares of common stock subject to the
Options shall be 110% of fair market value on the date of the grant ($.21 per
share).

     3. When Exercisable.

          (a) Provided that Executive is employed by the Company on the
     respective dates below, the Options shall vest as follows:

            Date                                     No. of Shares
            August 30, 1999                             500,000
            August 30, 2000                             500,000
            August 30, 2001                             500,000
            August 30, 2002                             500,000
            August 30, 2003                             500,000

          (b) Except as provided in paragraphs 2 and 3 of this Agreement, once
     any Option become exercisable they shall remain exercisable through August
     30, 2004.

          4. Conversion to Non-Qualified Options. In the event that the
     stockholders of the Company fail to approve the Plan within one year after
     approval by the Board of Directors, or in the event that the Executive is
     terminated with pursuant to Section 5 (a) or 5(d) of that certain
     Employment Agreement dated August 30, 1999 between the Company and the
     Executive, a copy of which, is on file at the Company's corporate office
     (the "Employment Agreement"), the exercise period for the Options shall be
     extended through August 30, 2009 thereby converting all of the Options to
     Non-Qualified Options. In such event, the Company shall pay Executive a
     tax-offset bonus each time he exercises any Options. The amount of the tax
     offset bonus shall be equal to the amount of federal income tax he incurs
     in connection with the exercise of the Options assuming he is at the
     highest marginal United States income bracket for the year of exercise.
     Such bonus shall be paid to Executive on or before February 1, of the year
     following exercise.
<PAGE>

     5. Termination of Relationship.

          (a) Except as set forth in Section 4 above, if for any reason, except
     death, Executive ceases to act as an employee of the Company, all rights
     granted hereunder shall terminate effective three months from the date
     Executive ceases to act as an employee.

          (b) If Executive shall die while an employee of the Company, his
     estate or any transferee, as defined herein, shall have the right within
     three months from the date of Executive's death to exercise Executive's
     Options to the extent the right to exercise to the Options shall have
     accrued at the date of death, except to the extent the Options shall have
     been exercised prior thereto. The exercise period for any Options not
     vested, shall be extended through August 30, 2004 thereby converting all of
     the Options to Non-Qualified Options. For the purpose of this Agreement,
     "transferee" shall mean a person to whom such shares are transferred by
     will or by the laws of descent and distribution.

          (c) No transfer of the Options by Executive by will or by the laws of
     descent and distribution shall be effective to bind the Company unless the
     Company shall have been furnished with written notice thereof and a copy of
     the letters testamentary or such other evidence as the board may deem
     necessary to establish the authority of the state and the acceptance by the
     transferee or transferees of the terms and conditions of the Options.

          (d) If Executive becomes disabled while employed by the Company within
     the meaning of Section 22(e)(3) of the Code, the three month period
     referred to in paragraph 3(a) of this Agreement shall be extended to one
     year.

     6. Method of Exercise/Registration. These Options shall be exercisable by a
     written notice, which shall:

          (a) state the election to exercise the Options, the number of shares
     to be exercised, the person in whose name the stock certificate or
     certificates for such shares of common stock is to be registered, his
     address and social security number (or if more than one, the names,
     addresses and social security numbers of such persons);

          (b) contain such representations and agreements as to the holder's
     investment intent with respect to such shares of common stock as set forth
     in paragraph 8 hereof;
<PAGE>

          (c) be signed by the person or persons entitled to exercise the
     Options and, if the Options is being exercised by any person or persons
     other than the Executive, be accompanied by proof, satisfactory to counsel
     for the Company, of the right of such person or persons to exercise the
     Options.

          (d) be accompanied by full payment of the purchase or exercise price
     there for either (i) in United States dollars in cash or by check; (ii) by
     Executive's personal recourse note bearing interest payable not less than
     annually at no less than 100% of the lowest applicable federal rate, as
     defined in Section 1274(d) of the Code; (iii) by having the Company retain
     a portion of the Shares covered by the option exercise, or (iv) by any
     combination of (i) (ii) and (iii) above.

     If the Executive chooses to pay the exercise price pursuant to (iii) above,
the number of Shares to be delivered to or withheld by the Company times the
fair market value shall equal the cash required for exercise. To the extent that
the Participant elects to either deliver or have withheld Shares of the
Company's Common Stock, the Board of Directors may require the Executive to make
such election only during certain periods of time as may be necessary to comply
with appropriate exemptive procedures regarding the "short-swing" profit
provisions of Section 16(b) of the Securities Exchange Act of 1934 or to meet
certain Internal Revenue Code requirements.

     The certificate or certificates for shares of common stock as to which the
Options shall be exercised shall be registered in the name of the person or
persons exercising the Options.

     The Company shall, if requested by the Executive, as expeditiously as
possible file a registration statement on a form of general use under the
Securities Act to permit the sale or other disposition of the Optioned Shares.
The Executive shall provide all information reasonable requested by the Company
for inclusion in any registration statement to be filed under this Agreement.
The Company will use its best efforts to cause such registration statement first
to become effective at the earliest practicable time and then to remain
effective for such period as the Executive reasonably deems necessary to effect
such sales or other dispositions or until all Optioned Shares no longer will
constitute "restricted securities" with the meaning of Rule 144 under the
Securities Act. Such registration shall be effected at the Company's expense
except for underwriting commissions and the fees and disbursements of the
Executive's counsel attributable to the registration of the Optioned Shares. The
Company and the Executive shall enter into an agreement under which each will
indemnify the other with respect to information provided by such party for use
in the registration statement, such indemnities and the procedures for them to
be in a form customarily included in registration rights agreements. The Company
further agrees to use its best efforts to register or qualify the Optioned Stock
covered under such registration statement under such other securities or
blue-sky laws of such jurisdictions as the Executive shall reasonably request.

     7. Reload Options. If the Executive pays all or a portion of the exercise
price of an Option or the tax required to be withheld pursuant to an exercise of
<PAGE>

an Option by surrendering shares of Stock pursuant to Section 6(d) above, the
Executive shall be automatically granted an Option for the purchase of Stock
equal to the number of shares surrendered (a "Reload Option"). The grant of the
Reload Option shall be effective on the date the Participant surrenders the
shares of Stock in respect of which the Reload Option is granted (the "Reload
Date"). The Reload Option shall have an exercise price equal to the Fair Market
Value of the Stock on the Reload Date, and shall have a term which is no longer,
and which shall lapse no later, than the original term of the underlying option.
If stock otherwise available under an Incentive Stock Option is withheld
pursuant to Section 6(d) above, any Reload Option granted in connection with the
withholding shall be treated as a new Incentive Stock Option, subject to the
rules set forth in the Plan..

     8. Adjustments. Upon the occurrence of any of the following events, the
Executive's rights with respect to Options granted hereunder shall be adjusted
as hereinafter provided unless otherwise specifically provided in the written
agreement between the Executive and the Company relating to such Option:

          (a) If the shares of Common Stock shall be subdivided or combined into
     a greater or smaller number of shares or if the Company shall issue any
     shares of Common Stock as a stock dividend on its outstanding Common Stock,
     the number of shares of Common Stock deliverable upon the exercise of
     Options shall be appropriately increased or decreased proportionately, and
     appropriate adjustments shall be made in the purchase price per share to
     reflect such subdivision, combination or stock dividend.

          (b) Except as provided for pursuant to Section 5 (a) or 5(d) of the
     Employment Agreement, if the Company is to be consolidated with or acquired
     by another entity in a merger, sale of all or substantially all of the
     Company's assets or otherwise (an "Acquisition"), the committee or the
     board of directors of any entity assuming the obligations of the Company
     hereunder (the "Successor Board") shall at the Executives sole option, as
     to outstanding Options, either (i) make appropriate provision for the
     continuation of such Options by substituting on an equitable basis for the
     shares then subject to such Options the consideration payable with respect
     to the outstanding shares of Common Stock in connection with the
     Acquisition; or (ii) terminate all Options in exchange for a cash payment
     equal to the excess of the fair market value of the shares subject to such
     Options (to the extent then exercisable) over the exercise price thereof.

          (c) In the event of a recapitalization or reorganization of the
     Company (other than a transaction described in subparagraph (b) above)
     pursuant to which securities of the Company or of another corporation are
     issued with respect to the outstanding shares of Common Stock, the
     Executive upon exercising an Option shall be entitled to receive for the
     purchase price paid upon such exercise the securities he would have
     received if he had exercised his Option prior to such recapitalization or
     reorganization.

          (d) Except as expressly provided herein, no issuance by the Company of
     shares of stock of any class or securities convertible into shares of stock
     of any class shall affect, and no adjustment by reason thereof shall be
     made with respect to, the number or price of shares subject to Options. No
     adjustments shall be made for dividends or other distributions paid in cash
     or in property other than securities of the Company.
<PAGE>

          (e) No fractional shares shall be issued pursuant to the Options, the
     Executive shall receive from the Company cash in lieu of such fractional
     shares.

          9. Necessity to Become Holder of Record. Neither the Executive nor his
     estate, as provided in paragraph 3(b), shall have any rights as a
     shareholder with respect to any shares covered by the Options until such
     person shall have become the holder of record of such shares. No adjustment
     shall be made for cash dividends or cash distributions, ordinary or
     extraordinary, in respect of such shares for which the record date is prior
     to the date on which he shall become the holder of record thereof.

          10. Reservation of Right to Terminate Relationship. Nothing contained
     in this Agreement shall restrict the right of the Company to terminate the
     relationship of Executive at any time, with or without cause. The
     termination of the relationship of Executive by the Company, regardless of
     the reason there for, shall have the results provided for in Section 5 of
     this Agreement.

          11. Conditions to Exercise of Options. In order to enable the Company
     to comply with the Securities Act of 1933 (the "Securities Act") and
     relevant state law, the Company shall require Executive, his estate, or any
     Transferee as a condition of the exercising of the Options granted
     hereunder, to give written assurance satisfactory to the Company that the
     shares subject to the Options are being acquired for his own account, for
     investment only, with no view to the distribution of same, and that any
     subsequent resale of any such shares either shall be made pursuant to a
     registration statement under the Securities Act and applicable state law
     which has become effective and is current with regard to the shares being
     sold, or shall be pursuant to an exemption from registration under the
     Securities Act and applicable state law.

          The Options are subject to the requirement that, if at any time the
     board of directors shall determine, in its discretion, that the listing,
     registration, or qualification of the shares of common stock subject to the
     Options upon any securities exchange or under any state or federal law, or
     the consent or approval of any governmental regulatory body, is necessary
     as a condition of, or in connection with the issue or purchase of shares
     under the Options, the options may not be exercised in whole or in part
     unless such listing, registration, qualification, consent or approval shall
     have been effected.

          12. Duties of Company. The Company will at all times during the term
     of Options:

               (a) Reserve and keep available for issue such number of shares of
          its authorized and unissued common stock as will be sufficient to
          satisfy the requirements of this Agreement;

               (b) Pay all original issue taxes with respect to the issue of

               (c) Use its best efforts to comply with all laws and regulations,

          thereto.
