PART I


ITEM 1. Description of Business

INTRODUCTION

American Dental Technologies, Inc. ("American Dental" or "Company")
develops, manufactures and markets high technology dental products designed for
general dentistry. American Dental's primary products are air abrasive kinetic
cavity preparation systems ("KCP"); pulsed dental lasers, primarily the
PulseMaster models; high speed curing lights ("PAC"); and intra oral cameras
("Ultracam") which are developed and manufactured at its manufacturing facility
in Corpus Christi, Texas. American Dental also develops, manufactures and
markets precision air abrasive jet machining ("AJM") systems for industrial
applications. American Dental, incorporated in Delaware in November 1989,
completed its initial public offering in June 1991.

On February 14, 2000, American Dental announced that it would now sell its
dental products in the United States directly to dentists through its own sales
force. The Company plans to establish twenty sales and service centers in 2000
and add twenty additional sales and service centers over the next two years.
American Dental plans to continue to sell outside the United States through its
distributor network. The goal of the Company is to become an equipment
distributor which supplies 80% to 90% of a dentist's equipment requirements. To
that end, the Company will pursue OEM relationships and strategic alliances with
other manufacturers.

PRODUCTS

KCP Cavity Preparation Systems

American Dental currently offers several KCP models which vary in size,
power and features, from the KCP 5 counter top model to the deluxe KCP 1000PAC
model. American Dental's KCP products remove tooth decay and tooth structure,
including enamel, by means of a narrow stream of minute particles of alpha
alumina propelled at high velocity by compressed air and delivered to the tooth
via a lightweight handpiece. The KCP shapes restoration sites, removes old
composites and modifies underlying hard tissue, often helping to increase bond
strength. It is also used for sealant preparations, stain removal and intraoral
porcelain removal and repair. The KCP can often be used in place of a drill and
may be used in many cases without anesthesia. The dentist controls the cutting
speed by selecting particle size (27 or 50 micron) and air pressure (40 psi to
160 psi) with touch pads on a control panel. The air abrasive stream is
activated by a foot pedal. The KCP floor models (KCP 100 and KCP 1000) are
contained in a movable cabinet the size of a medium suitcase and plug into a
standard electrical outlet.

The KCP is best used in conjunction with modern tooth-colored composite
restoration materials. It is not recommended for removing large amalgam
fillings. The precision of the KCP, and the manner in which it prepares surfaces
for restorations, allow for earlier treatment of decay and less destruction of
the tooth while restoring it. In many cases, the KCP may be used without
anesthesia, allowing a dentist to treat teeth in different quadrants of the
mouth during a single visit. This is generally not possible when conventional
instruments and anesthesia are used.

American Dental also markets a Plasma Arc Curing System ("PAC") as an
accessory to its KCP and as a stand alone unit. The PAC utilizes a high
intensity light source to rapidly cure composite fillings. Curing occurs in five
to ten seconds, or at least twice as fast as most conventional curing lights.
The KCP1000 PAC combines an air abrasive cavity preparation system together with
a composite curing light in a single instrument. This allows dentists to
efficiently switch from cavity preparation to curing.

The KCP is sold primarily in North America, certain Asian and Pacific
markets and Europe. The KCP and PAC represented approximately 41%, 65%, and 76%
of American Dental's total revenues in 1999, 1998 and 1997, respectively.

Laser Products

The PulseMaster 600-IQ, one of two instruments in American Dental's laser
product line, is a neodymium yttrium-aluminum-garnet (Nd:YAG) laser that
delivers pulses of laser energy through a flexible fiber optic delivery system
that can reach into difficult recesses of the mouth. The PulseMaster can deliver
a 100-microsecond energy pulse at rates varying from 10 to 200 times per second,
up to six watts of average power. The PulseMaster is contained in a movable
cabinet the size of a medium suitcase, weighs approximately 75 pounds and plugs
into a standard electrical outlet.

American Dental introduced a diode laser, "Diolase", in October 1998. The
diode laser delivers a continuous wave or gated continuous wave through a
flexible fiber optic delivery system that can reach difficult recesses of the
mouth. The Diolase delivers up to 6 watts of power depending upon the fiber size
used. The Diolase is compact and portable in size, weighs approximately 11
pounds and plugs into a standard electrical outlet.

American Dental's dental lasers, components and accessories are sold
primarily in certain Asian and Pacific markets, Europe and North America. Lasers
represented approximately 27%, 17% and 15% of American Dental's total revenues
during 1999, 1998 and 1997, respectively.

American Dental believes one important feature of its dental lasers is
their ability to help reduce the pain associated with the procedures for which
they are used. Additionally, because the laser is more precise than standard
dental instruments, its use results in less cellular destruction. The laser
minimizes bleeding during soft tissue surgery, creating a cleaner field in which
to operate by eliminating time-consuming removal of blood from the operative
site. The laser also reduces the risk of post-operative infection.

American Dental's dental lasers are used for both soft tissue and hard
tissue applications. Soft tissue procedures include removing excess or diseased
gum tissue, contouring gums, performing biopsies, preparing gums for crown and
bridge impressions, trimming the gums to fit crowns and bridges, treating gum
disease and for hemostasis (control of bleeding). Hard tissue applications
include removing early decay from teeth, etching, increasing hardness of dentin,
and desensitizing and anesthetizing teeth. In May 1999, American Dental
Technologies received U.S. Food & Drug Administration ("FDA") clearance to
market the PulseMaster for the selective removal of enamel decay. American
Dental has not received clearance from the FDA to market dental lasers in the
United States for any other hard tissue application, but does market these
instruments in certain other countries for such purposes. See "Governmental
Regulation."

Intra Oral Camera Products

The Ultracam is a sophisticated camera system that allows the dentist to
take pictures of a patient's teeth during an examination. The pictures can be
projected on a video monitor in the examination room for immediate viewing by
the dentist and the patient and printed or stored on a computer disk. The
Ultracam systems offered vary in size from the basic cart system, which is a
portable camera and printer housed in a mobile cart, to a networked system that
can be utilized in several examination rooms. The networked systems combine the
cart system with central printing stations, digital docking stations and
examination room monitors.

The Ultracam is utilized in the dental practice for presentation, education
and as a means of communicating their services through multi-media. The recently
introduced Digital Docking Station greatly enhances the value of an intra oral
camera by allowing the storage of up to 40 images on a 3 1/2" computer floppy
disk.

Ultracam products are sold primarily in North America and Europe. Since its
acquisition in August 1998, the Ultracam products represented approximately 22%
and 11% of American Dental's total revenue in 1999 and 1998, respectively.

Industrial Products

American Dental also develops, manufactures and markets precision air
abrasive jet machining ("AJM") systems for industrial applications. AJM has a
wide range of applications, including drilling, cutting, abrading, deburring,
dressing, beveling, etching, shaping and polishing. Its principal advantage over
conventional machining is that the AJM process, which accomplishes its work
through kinetic particle displacement (an erosion process), produces no heat,
shock or vibration. This enables precise work to be done on fragile materials
without deburring or further processing. Generally, the same is not true of
drills, saws, laser or other types of conventional machining equipment because
all of these systems rely on heat and/or friction to perform the work. These
machining techniques generally require further processing and in many instances
do not provide the precision available with AJM, particularly with fragile
materials. AJM systems are often used to remove the slag, burrs and flash
resulting from conventional machining processes. Some examples include deburring
needles, beveling silicon wafers and cutting fiber optics.

Industrial products accounted for less than 5% of American Dental's total
revenues in 1999, 1998, and 1997, respectively.

Probe and Chart-It

The Probe One is a computerized periodontal probe which works with practice
management software to automate and streamline perio-probing and charting.
Chart-It is an automated charting software program used to fully integrate a
dentist's operatory with most front office practice management systems. These
products represented less than 1% of the Company's total revenues in 1999, 1998
and 1997.

MARKETING, SALES AND TRAINING

General

Prior to February 14, 2000, American Dental marketed its dental products
through independent distributors, primarily Patterson Dental Company and
Sullivan Schein, Inc., to general dental practitioners and certain other dental
specialists in the United States. Sales to Patterson Dental Company, a major
domestic distributor of the Company's kinetic cavity preparation units, were
approximately 16%, 30%, and 34% of total revenues in 1999, 1998, and 1997,
respectively.

On February 14, 2000, American Dental commenced selling its dental products
in the United States to dentists through its own sales force. The new business
model for the United States does not merely encompass direct selling by the
Company's own sales force. American Dental intends to become a distributor of
dental equipment by establishing the infrastructure to support direct selling.
American Dental will not only sell dental products it manufactures, but also
intends to actively pursue OEM or strategic relationships with other
manufacturers. Within five years, it hopes to be able to supply 80% to 90% of
the equipment used by dentists.

The new business model calls for the establishment of 20 dental sales and
service centers in the year 2000 and 20 more in the following two years. Each
center will be staffed with an office coordinator responsible for scheduling,
coordinating local marketing and reporting to corporate headquarters.
Additionally, each center will have a technician for installation and technical
service support. Outside the United States, including Canada, American Dental
will continue selling its dental products through its strong distributor
network.

American Dental's products are exclusively marketed in Japan by Denics Co.
Ltd. ("Denics") or its affiliates. As of March 2000, American Dental has
purchase commitments of approximately $4,560,675 through March 2001. Sales to
Denics for certain Asian and Pacific markets, primarily Japan, were
approximately 19%, 12%, and 10% of total revenues in 1999, 1998, and 1997,
respectively.

In most of Europe, American Dental's products are marketed through
exclusive dental distributors, such as DLMedica in Italy, Casa Schmidt in Spain
and Dentex in Russia. In Germany, the Company's primary European market,
American Dental is selling directly to the end user as well as selling through
distributors. An agreement was signed February 15, 2000 authorizing Plessing
Dental Handel GmbH and their affiliate, Sirona, to



4
5




act as the exclusive laser distributor for Germany, provided these two firms
sell a minimum of 72 laser units during the balance of 2000. This agreement only
covers distributor sales in Germany and allows American Dental's German
subsidiary to continue to sell all of American Dental's products directly to the
end user.

The loss of American Dental's relationship with any of its international
dental product distributors or their failure to meet purchase commitments could
have a material adverse effect on American Dental's business.

Marketing activities, such as dental exhibitions and meetings, are
typically lower in the summer months, which results in decreased revenues during
the third quarter of the year.

American Dental presently has several industrial product distributors. Such
distributors have been and are anticipated to be the primary source of sales for
American Dental's industrial products in the future. Industrial product
distributors are supported by American Dental primarily through advertising in
the Thomas Register and trade journals, and by participation in trade shows.

American Dental also sells some industrial products directly to customers
through advertisements or customer referrals and through original equipment
manufacturers of grinding equipment who purchase AJM systems to incorporate into
their equipment.

INSTALLATION, TRAINING AND SERVICE

Because American Dental's dental products represent new approaches to
dentistry, installation and training are considered to be significant aspects of
its marketing efforts. Shortly after any purchase, American Dental or the
selling distributor install the product, verify that it is in proper working
order and provide training on its lasers and large air abrasion units. American
Dental also encourages each purchaser to participate in ongoing continuing
education regarding the use of American Dental's dental products and endeavors
to share new developments as soon as reliable scientific support has been
established.

American Dental or its distributors generally provide warranty service for
American Dental's products in the United States. To service its dental products,
American Dental has five full-time service employees in the United States and
has service arrangements with independent distributors for products in other
markets. Additionally, new service employees will be added as the sales and
service centers are opened. If such arrangements are unavailable, certain of
American Dental's sales personnel are trained to make minor service repairs. To
date, American Dental has not experienced significant service problems.
Previously, the warranty for a KCP, PAC, camera or laser was one year. The
general warranty was extended to two years in the United States for sales after
February 14, 2000. American Dental provides a limited five year warranty that a
PAC will deliver full curing energy in the calibrated time of ten seconds or
less.

The Company has a service center in Keltern, Germany which provides
installation, training, service and technical support for Europe, Russia and the
Mid-East. In other international markets, the distributors provide installation,
training and service with technical support from the United States office.

SUPPORT OF EDUCATIONAL ACTIVITIES

Because American Dental's dental products represent new approaches to
dentistry, American Dental believes a substantial effort is required to educate
dentists regarding the advantages of its technology. American Dental actively
supports educational activities relating to the use of its products.

Dr. Terry Myers, an American Dental consultant, is the executive director
of The Institute for Advanced Dental Technologies, formerly The Institute for
Laser Dentistry (the "Institute"). Under the auspices of the Institute, Dr.
Myers lectures at dental meetings and institutions throughout the world and
publishes professional papers and articles. The Institute also supervises the
training of clinical instructors, provides clinical instructors to lead
educational programs, evaluates developments in dental technology and organizes
clinical training programs. American Dental supports these programs by providing
financial support to the Institute, soliciting enrollments, providing loans of
equipment and assisting in the preparation of course materials. Following the
completion of a program, an American Dental sales representative is typically
available to answer questions concerning American Dental's products.

COMPETITION

In general, American Dental's products are subject to intense competition,
both from other advanced dental technology companies and from makers of
conventional dental equipment. American Dental believes there are approximately
ten companies which presently sell competing dental air abrasive products and
approximately eleven companies which presently sell competing intra oral camera
systems. American Dental believes there are approximately eight competing
companies which presently offer Nd:YAG, diode, argon, erbium, holmium or CO2
lasers for use in dentistry. American Dental has patents in the basic
technologies, both in air abrasion and lasers, which the Company believes
provide a competitive advantage.

American Dental's KCP, PAC and Laser products must also compete with
conventional treatment methods using dental instruments or equipment which are
generally less expensive and with which dentists are more familiar.

Many of these competing companies, particularly those which manufacture
traditional dental equipment, may have been in business longer, have greater
resources and have a larger distribution network than American Dental. American
Dental's competitive position is dependent upon its pricing and marketing
practices, its ability to make ongoing improvements in its existing products, to
develop new products, and to successfully promote the capabilities and treatment
benefits of its products. While American Dental believes its products are
competitive in terms of capabilities, quality and price, competition has, and
may in the future, adversely affect American Dental's business.

PATENTS

American Dental believes its patents provide a competitive advantage in
those countries where they have been issued. American Dental believes its air
abrasive technology patents and other patent rights provide a proprietary means
to utilize that technology in dentistry. In the United States, American Dental
has patents related to dental air abrasive systems and methods for using an air
abrasive stream for dentistry that do not begin expiring until 2011, technology
patents for air abrasive cavity preparation systems that do not begin expiring
until 2004, dental laser method and technology patents that have expiration
dates ranging from 2002 to 2016, and industrial air abrasive patents that have
expiration dates ranging from 2004 to 2016. American Dental also holds several
industrial air abrasive patents in various other countries.

MANUFACTURING AND SUPPLIERS

American Dental manufactures, assembles and services its products at its
ISO 9001-certified facility in Corpus Christi, Texas. Certification under the
ISO 9001 standard represents the highest level of facility certification
attainable. Manufacturing certification became a requirement for all medical
products distributed or sold in Europe as of July 1, 1998.

American Dental's products are manufactured from parts, components and
subassemblies obtained from a number of unaffiliated suppliers and/or fabricated
internally at its manufacturing facility. American Dental has modern machining
capability allowing it to control the production of certain non-standard parts.
American Dental uses numerous suppliers for standard parts and for fabrication
of certain parts. Although most of the parts and components used in its products
are available from multiple sources, American Dental presently obtains several
parts and components from single sources. Lack of availability of certain parts
and components could result in production delays. Management has identified
alternate suppliers and believes any delays would be minimal. While the loss of
American Dental's relationship with a particular supplier might result in some
production delays, such a loss is not expected to materially affect American
Dental's business.

RESEARCH AND DEVELOPMENT

Most research and development, prototype production and testing activities
take place at the Texas facility, although some research and development work is
performed for American Dental by consultants. The Texas facility has an
engineering and CAD/CAM drafting staff which is capable of producing new product
prototypes. Although American Dental expects to continue to conduct most of its
own research and development activities, American Dental will continue to work
with various domestic and international dental schools, consultants and
researchers to analyze dental applications and to develop product enhancements
and complementary products.



6
7

American Dental's research and development expenditures for 1999, 1998 and
1997 were $931,189, $947,202 and $641,984, respectively. American Dental's
current research and development efforts are focused on new complementary
products for the dental market.

GOVERNMENTAL REGULATION

American Dental's dental products are subject to significant governmental
regulation in the United States and certain other countries. In order to conduct
clinical tests and to market products for therapeutic use, American Dental must
comply with procedures and standards established by the United States Food and
Drug Administration ("FDA") and comparable foreign regulatory agencies. Changes
in existing regulations or adoption of additional regulations may adversely
affect American Dental's ability to market its existing products or to market
enhanced or new dental products.

United States Regulatory Requirements

The FDA granted clearance to market the KCP for hard-tissue applications
and the PulseMaster dental lasers for soft-tissue procedures in late 1992.
Clearance to market the PAC was granted by the FDA in mid-1995. The PulseMaster
received FDA clearance to market for laser curettage in March 1997 and a diode
laser was granted soft tissue clearance in September 1997. The Pulsemaster
received FDA clearance to market for selective removal of enamel dental caries
in May 1999. The receipt of FDA clearance requires proof of the product's safety
and efficacy or that the product is substantially equivalent to products which
have already received FDA clearance. Such clearances, if obtained, may take from
three months to several years to receive.

Foreign Regulatory Requirements

The KCP, PAC, Intraoral cameras and Lasers have been granted CE mark
approvals which are recognized by most European countries, and may be sold in
Germany and many other European markets. In the latter part of 1996, approval to
market the KCP in Japan was obtained. American Dental's dental lasers comply
with government regulations in most major countries in Europe, Asia, the Pacific
Rim, and North and South America and are marketed for both hard and soft tissue
applications, except in Japan, where (as in the United States) they have not
been cleared for certain hard-tissue procedures. Additional foreign
authorizations to market its dental products are being sought where needed.
Regulation of medical devices in other countries varies between countries such
as Japan, which has standards similar to the FDA, to countries which have no
regulations. Regulation of medical devices in other countries is also subject to
change and there can be no assurance American Dental will continue to be able to
comply with such requirements.

European regulations required ISO 9001 certification as of July 1998 for
all medical products distributed or sold in Europe. American Dental's
manufacturing facility received ISO 9001 certification in 1997.

PRODUCT LIABILITY EXPOSURE

American Dental's business involves the inherent risk of product liability
claims. If such claims arise, they could have an adverse effect on American
Dental. American Dental currently maintains product liability insurance on a
"claims made" basis with coverage per occurrence and in the aggregate annually
of $5,000,000. There is no assurance that such coverage will be sufficient to
protect American Dental from all risks to which it may be subject or that
product liability insurance will be available at a reasonable cost, if at all,
in the future.

FOREIGN OPERATIONS

See "American Dental Technologies, Inc. Notes to Financial Statements, Note
8."

EMPLOYEES

On March 1, 2000, American Dental had 95 full-time employees and 2
part-time employees. Of these employees, 24 were engaged in direct sales and
marketing activities and 55 in manufacturing activities. The remaining employees
are in finance, administration, customer service, and research and development.
American Dental has no collective bargaining agreements with any unions and
believes that its overall relations with its employees are good.

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


Results of Operations

For the year ended December 31, 1999, income before taxes was $1,007,606
compared to $3,777,200 for 1998. The decline in income before taxes was
primarily attributable to a decline in revenues and gross margins, and an
increase in selling and marketing expenses for the first half of 1999 as a
percentage of revenues.

For the year ended December 31, 1998, income before taxes was $3,777,200
compared to $3,621,770 for 1997. The increase in income before taxes was
primarily due to increased revenues, which was partially offset by increased
legal fees incurred during 1998 for defending the Company's business reputation
and patents.

For the year ended December 31, 1999, the Company's revenues decreased 14%
compared to 1998. This decrease in revenues is primarily due to 27% decrease in
revenues in North America, partially offset by a 39% increase in revenues in
Japan and a 41% increase in Europe. The decrease in North American revenues is
primarily due to a decrease in KCP sales caused by the liquidation of dealer
inventories and a soft air abrasion market. The Company is attempting to reduce
fluctuations resulting from dealer inventory adjustments by implementing the new
business model described in Item I. Sales of lasers, PAC lights and intraoral
cameras increased in North America during 1999, partially off-setting the softer
KCP sales. The increase in revenues in Europe are mainly attributable to the
addition of new distributors in 1999.

For the year ended December 31, 1998, the Company's revenues increased 31%
compared to 1997. This increase in revenues is primarily due to a 32% increase
in revenues in North America, a 44% increase in revenues in Japan and a 2%
increase in Europe. The increase in North America is due to the addition of the
Ultracam intra oral product line as a result of the acquisition of Dental Vision
Direct in August 1998 and increased sales of the stand alone curing light. The
Japanese and European distributors had reduced purchasing in 1997 and 1996 to
lower their inventory levels.

Gross profit as a percentage of revenues was 48% for the year ended
December 31, 1999, compared to 54% in 1998 and 57% in 1997. The decrease in
gross profit as a percentage of revenues in 1999 compared to 1998 and 1997 is
due to price discounts extended to North American distributors and a change in
product mix with lower gross profit as a percentage of revenues on the Ultracam
product line acquired in August 1998.

Selling, general and administrative expenses were $10,772,746 in 1999,
$10,618,210 in 1998 and $8,418,271 in 1997. The increase in 1999 is primarily
attributable to sales and marketing expenses in the first half of the year which
were higher as a percentage of sales primarily due to increased selling,
marketing, and general and administrative expenses related to the camera
business acquired from Dental Vision Direct and amortization of goodwill also
related to the camera business. The increase in 1998 is attributable to
increased selling and marketing expenses in North America and legal expenses
in excess of $500,000 for the purpose of defending the Company's business
reputation and patents.

Research and development expenses were $931,189 in 1999, $947,202 in 1998,
and $641,984 in 1997. The expenditures related primarily to the development of a
new PAC light and two new products which have not been completed. The increase
in research and development expense during 1998 was due to expenses relating to
clinical reports for regulatory approvals and the completion of two new
products.

License transfer fees increased $665,000 for the year ended December 31,
1999 compared to 1998. This increase is primarily due to the licensing
agreement with ESC Medical Systems, Ltd. for $300,000, a licensing agreement
with Chart-It for $65,000 and settlement of $300,000 from Kreativ regarding
patent litigation.

Other income increased $715,050 for the year ended December 31, 1999
compared to 1998. This increase is primarily due to the Kreativ lawsuit
settlement of $580,000 and a gain on the sale of the Michigan building of
$180,000.

Interest expense was $401,438 in 1999, $206,856 in 1998, and $52,857 in
1997. The increase in interest expense in 1999 and 1998 is primarily due to the
debt incurred to fund the acquisition of DVD in August 1998.

In 1999, the Company recorded a $616,000 charge for income tax. The
Company's income taxes at U.S. statutory rates, differs from its recorded income
tax expense primarily due to nondeductible goodwill amortization. In 1998, the
Company reversed its previously recorded deferred tax asset valuation allowance
as the Company determined that it was more likely than not that it would realize
the related deferred tax asset. The effect of the reversal was to increase net
income by $5,072,117 for this income tax benefit. The Company's income taxes at
U. S.


11
12

statutory rates differs from its recorded income tax benefit primarily due to
the reversal of a previously recorded deferred tax valuation allowance in 1998.
At December 31, 1999, the Company had net deferred tax assets totaling
$4,744,000, primarily consisting of a net operating loss carryforward of
$3,746,000. These net operating loss carryforwards expire in various amounts in
the years 2006 through 2011.

Liquidity and Capital Resources

The Company's operating activities provided $2,818,774 in cash resources in
1999. Cash provided by operating activities in 1999 was due to net income of
$391,606, a decrease in inventories of $1,401,007, a decrease in accounts
receivable of $211,110, $558,619 of non-cash change in deferred taxes and
$1,868,378 of non-cash depreciation and amortization expense. Cash provided by
operating activities was primarily offset by reductions in liabilities totaling
$1,833,462.

The Company's investing activities used $149,095 in cash resources in 1999.
The cash used in investing activities in 1999 related primarily to the expansion
of the Company's facility in Corpus Christi, Texas, partially offset by the sale
of its office in Southfield, Michigan.

On September 30, 1999, the Company renewed an agreement for a $7,500,000
revolving line of credit from a bank, with interest at prime or the LIBOR rate
(Eurodollar rates, which were approximately 6.0% at December 31, 1999) plus
1.5%, which expires in September 2001. The Company's borrowing is secured by a
pledge of the Company's accounts receivable, inventory, equipment, instruments,
patents, copyrights and trademarks. As of December 31, 1999, the Company had
$5,150,000 outstanding and $2,350,000 available under this line of credit. The
borrowings were used to fund the Company's acquisition of DVD.

The Company believes, based upon its current business plan, that current
cash, available financing resources and cash generated through operations should
be sufficient to meet the Company's anticipated short term and long term
liquidity needs for the foreseeable future.

Impact of Year 2000

In prior years, the Company discussed the nature and progress of its plans
to become Year 2000 ready. During 1999, the Company completed its remediation
and testing of systems. As a result of those planning and implementation
efforts, the Company experienced no significant disruptions in mission critical
information technology and non-information technology systems and believes those
systems successfully responded to the Year 2000 date change. The Company
incurred costs of approximately $50,000 in connection with remediating its
systems and anticipates no further costs. The Company is not aware of any
material problems resulting from Year 2000 issues, either with its products, its
internal systems, or the products and services of third parties. The Company
will continue to monitor critical computer applications and those of its
suppliers and vendors throughout the year 2000 to ensure that any latent Year
2000 matters that may arise are addressed promptly.

ITEM 7a. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In the normal course of business, the Company is subject to market risk
from changes in foreign exchange rates, interest rates and raw material prices.

Foreign Currency

The Company sells its products in North America, Europe (primarily
Germany), Japan and other foreign countries. The Company is headquartered in the
United States and has a German subsidiary. Except for revenues generated by its
German subsidiary, the Company sells its products to its foreign customers in
United States dollars. As a result the Company's financial results could be
affected by factors such as changes in foreign currency exchange rates or weak
economic conditions in the foreign markets in which the Company distributes its
products. The Company's operating results are primarily exposed to changes in
exchange rates between the United States dollar and the German deutsche mark.


12

13

As currency rates change, translation of the income statements of the
Company's German subsidiary into United States dollars affects year-to-year
comparability of operating results. The Company does not generally hedge
operating translation risks because cash flows from the German operations are
generally reinvested locally.

As of December 31, 1999 and 1998, the Company's net assets (defined as
current assets less current liabilities) subject to foreign currency translation
risk were $1,562,051 and $964,512 in 1998. The potential decrease in net assets
from a hypothetical 10% adverse change in quoted foreign currency exchange rates
would be approximately $156,205 and $96,541 for 1999 and 1998, respectively.

Interest Rate Risk

The Company's variable interest expense is sensitive to changes in the
general level of United States and European interest rates. The Company's long
term debt represents borrowings under a revolving line of credit at the bank's
prime rate and various notes at Eurodollar rates plus 1.5% and is sensitive to
changes in interest rates. The borrowings under the Eurodollar rates have
maturity dates varying between 30 to 120 days. At December 31, 1999, the
weighted average interest rate on the $5,150,000 debt was 7.22% and the fair
value of the debt approximates its carrying value.

The Company had interest expense of $401,438 in 1999 as compared to
$206,856 in 1998. The potential increase in interest expense from a hypothetical
2% adverse change, assuming the December 31, 1999 and 1998 debt was outstanding
for the entire year, would be approximately $103,000 and $118,000 for the year
ended December 31, 1999 and 1998, respectively.

1. Organization and Significant Accounting Policies


Principles of Consolidation

American Dental Technologies, Inc. (the "Company") develops, manufactures,
markets and sells high technology products for dentistry. The consolidated
financial statements include the accounts and operations of the Company and its
subsidiary. All intercompany transactions and balances have been eliminated.

Inventories

Inventories are stated at the lower of cost, determined by the first-in
first-out method, or market. At December 31, inventories consisted of the
following:




1999 1998
------------ -------------

Finished goods $ 1,310,448 $ 1,255,608
Raw materials, parts and supplies 8,627,757 9,969,600
------------ -------------
$ 9,938,205 $ 11,225,208
============ =============


Inventories at December 31, 1999 and 1998 are net of valuation allowances of
$811,715 and $555,000, respectively.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation.
Depreciation is computed by the straight-line method over the estimated useful
lives of the related assets, which range from three to thirty-nine years. At
December 31, property and equipment consisted of the following:




1999 1998
------------ -----------

Building and improvements $ 1,546,745 $ 1,469,583

------------ -----------
$ 2,447,906 $ 2,462,747
============ ===========


Intangible Assets

Intangible assets consist of goodwill, air abrasive technology rights, patents,
distribution rights and organization costs and are stated at cost less
accumulated amortization. The Company is amortizing goodwill over periods
ranging from 15 to 25 years, air abrasive technology rights over 10 years and
other intangible assets over lives ranging from 5 to 17 years. Accumulated
amortization was $5,806,049 and $4,351,647 at December 31, 1999 and 1998,
respectively.

The Company periodically evaluates intangible assets for indicators of
impairment in value. When impairment is indicated, the Company revalues the
assets based on their estimated fair value.

Revenue Recognition

The Company recognizes revenues and related estimated warranty expense when
title is transferred to the customer, generally upon shipment. The Company
recognized revenue on certain sales to two of its largest distributors under
terms which require shipment to a local independent warehouse during 1997 and
1998.

Translation of non-U.S. currency amounts

For non-U.S. subsidiaries which operate in a local currency environment, assets
and liabilities are translated to U.S. dollars at the current exchange rates at
the balance sheet date. Income and expense items are translated at average rates
of exchange prevailing during the year. Translation adjustments are accumulated
in a separate component of stockholders' equity.

Stock Based Compensation

The Company grants stock options for a fixed number of shares to employees with
an exercise price no less than the fair value of the shares at the date of
grant. The Company accounts for stock option grants in accordance with APB
Opinion No. 25, Accounting for Stock Issued to Employees, and, accordingly,
recognizes no compensation expense for the stock option grants.

Advertising

The Company expenses advertising costs as incurred. Advertising expense
approximated $603,400, $1,353,500 and $1,042,000 in 1999, 1998 and 1997,
respectively.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principals requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from these estimates.

1. Organization and Significant Accounting Policies (continued)

Fair Value of Financial Instruments

The fair value of the Company's cash, accounts receivable, note receivable,
accounts payable and note payable to the bank approximates their carrying value
due to their short term nature.

Reclassifications

Certain amounts in prior year financial statements have been reclassified to
conform with the presentation used in 1999.

2. Business Acquisitions

Dental Vision Direct

On August 1, 1998, the Company acquired 100% of the outstanding stock of Dental
Vision Direct ("DVD"), which manufactures and markets intra oral cameras and
related equipment. The total consideration paid was $7,620,000, including
$3,000,000 in cash, a promissory note of $3,900,000 and warrants to purchase
600,000 shares of Company common stock at a price of $5.50 per share. The
$3,900,000 promissory note was repaid in October 1998 with proceeds from the
line of credit as described in Note 4. The acquisition was accounted for as a
purchase and, accordingly, the total consideration paid of $7,620,000 has been
allocated to the acquired assets and assumed liabilities based on their
estimated fair values as of the acquisition date and the excess consideration of
$4,367,000 has been allocated to goodwill to be amortized over a 25 year period.
The results of operations for DVD have been included in the consolidated
statements of operations for the Company from the acquisition date.

The following unaudited pro forma financial information for the twelve months
ended December 31, 1998 and 1997 assume the DVD acquisition occurred as of the
beginning of the respective periods, after giving effect to certain adjustments,
including the amortization of intangible assets, interest expense on acquisition
debt and income tax effects. The pro forma results have been prepared for
comparative purposes only and are not necessarily indicative of the results of
operations which may occur in the future or that would have occurred had the
acquisition of DVD been consummated on the dates indicated, nor are they
necessarily indicative of the company's future results of operations.




Year Ended December 31
1998 1997

Revenues $32,313,902 $29,081,521
Net income 8,402,401 2,270,229

The Dental Probe

On February 15, 1998, the Company acquired 100% of the outstanding stock of the
Dental Probe, Inc. ("TDP") in exchange for $250,000 in cash and 61,500 shares of
common stock. The acquisition was accounted for as a purchase and accordingly,
the total consideration paid of $557,500, has been allocated to the acquired
assets and assumed liabilities based on their estimated fair values as of the
acquisition date and the excess consideration of $392,500 has been allocated to
goodwill to be amortized over a fifteen year period. The results of operations
for TDP have been included in the consolidated statements of operations for the
Company from the acquisition date.

3. Agreements with Related Parties

Denics Co., Ltd.

In December 1999, the Company agreed to convert $675,000 of outstanding accounts
receivable from Denics to a note receivable, with interest payable at 8.5%, due
February, 2001.

In February 1998, the Company agreed to convert $500,000 of outstanding accounts
receivable from Denics to a note receivable, with interest payable at 10.5% due
in September 1998. In August 1998, the Company agreed to modify the repayment
terms of the note receivable to $200,000 due August 31, 1998 and five monthly
installments of $60,000 commencing in April 1999. The note was paid in full in
September, 1999.

Sales of lasers and KCPs to Denics were $4,536,007, $3,465,819 and $2,060,505 in

$1,131,693 and, $1,143,475 from Denics at December 31, 1999 and 1998,
respectively.

Denics owned 4.89% and had warrants to acquire an additional 1.43% of the
Company's common stock. These warrants expired in 1999 and Denics is no longer
considered a "related party". However, the Company has disclosed its trade sales
and accounts receivable balances with Denics as a "related party" on the face of
the financial statements for all periods presented to provide consistent
disclosure.

Other

The Company obtained consulting and research services from related parties and
paid approximately $159,200 in 1997 for such services. There was no such expense
in 1999 and 1998.

4. Line of Credit and Other Non-Current Liabilities

On September 30, 1999, the Company renewed an agreement for a $7,500,000
revolving line of credit from a bank, with interest at prime or the LIBOR rate
(Eurodollar rates, which were approximately 6.0% at December 31, 1999) plus
1.5%, which expires in September 2001. The Company's borrowing is secured by a
pledge of the Company's accounts receivable, inventory, equipment, instruments,
patents, copyrights and trademarks. As of December 31, 1999, the Company had
$5,150,000 outstanding and $2,350,000 available under this line of credit.

5. Stockholders' Equity, Stock Options and Warrants

The Company has authorized three stock option plans for employees, officers,
directors, consultants and other key personnel. As of December 31, 1999, the
Nonqualified Stock Option Plan has 287,500 shares reserved, 72,804 shares
available for issuance and 172,409 shares outstanding; the Long-Term Incentive
Plan has 625,000 shares reserved, 108,802 shares available for issuance and
436,649 shares outstanding; and the Stock Option Plan for Employees has 17,405
shares reserved, 1,166 shares available and 13,536 shares outstanding

The Company also authorized and granted 81,392 stock options exclusive of the
above described plans, of which 48,721 options have been exercised or canceled
and 32,670 options were outstanding at December 31, 1999.

The Company has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" (APB 25) and related Interpretations
in accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under FASB Statement No. 123,
"Accounting for Stock-Based Compensation," requires use of option valuation
models that were not developed for use in valuing employee stock options. Under
APB 25, because the exercise price of the Company's employee stock options
equals the market price of the underlying stock on the date of grant, no
compensation expense is recognized.

Pro forma information regarding net income and earnings per share is required by
Statement 123 and has been determined as if the Company had accounted for its
employee stock options under the fair value method of that Statement. The fair
value for these options was estimated at the date of grant using a Black-Scholes
option pricing model with the following weighted-average assumptions for 1997,
1998 and 1999, respectively: risk-free interest rate of 6.5%; dividend yield of
0%; volatility factors of the expected market price of the Company's common
stock of 1.1, .373 and 1.437 and a weighted-average expected life of the option
of five years.

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price volatility. Because
the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

For purposes of pro forma disclosures, the estimated fair value of the option is
amortized to expense over the options' vesting period. The Company's pro forma
information follows:





1999 1998 1997
--------- ---------- ----------


Proforma net income $ 366,875 $ 8,438,709 $ 3,213,783
Proforma net income per share $ 0.05 $ 1.15 $ 0.46
Proforma net income per share
assuming dilution $ 0.05 $ 1.14 $ 0.42

those warrants is 4 years.

6. Transfer of License

In June 1997, the Company agreed to the transfer of the licenses for the sales
of dental lasers and air abrasive instruments from Sunrise Technologies, Inc.
("Sunrise") to Lares Co. ("Lares") in connection with the sale of Sunrise's
dental business to Lares. The Company received a payment of $275,000 and a note
receivable for $100,000, due in June 2000. The Company will also continue to
receive royalties on air abrasive and dental lasers from Lares.

In 1999, the Company sold a license to ESC Medical Systems, Ltd. for $300,000
for the use of certain patents. The Company delivered the license to ESC
Medical Systems, Ltd in 1999 and recorded the income in 1999 as a license
transfer fee since the Company has no additional requirements under this
license.

7. Income Taxes

At December 31, 1999, the Company had a $11,018,472 net operating loss
carryforward for federal income tax purposes, which expire in various amounts in
the years 2006 through 2011.

Deferred tax assets represent the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and amounts used for income tax purposes. Significant components of the
Company's deferred tax assets are as follows:

7. Income Taxes (continued)


In 1998, the Company reversed its previously recorded deferred tax asset
valuation allowance as the Company determined that it was more likely than not
that they would realize the related deferred tax asset. The effect of the
reversal was to increase net income by $5,072,000 for this income tax benefit.
The Company paid no income tax during 1999. Income taxes paid were approximately
$134,400 and $94,100 in 1998 and 1997.

The Company's investment in its foreign subsidiary are considered to be
permanently invested and no provision for U.S. federal and state income taxes on
these translation adjustments have been provided.

8. Operations by Industry Segment, Geographic Area and Significant Customers

The Company adopted SFAS No. 131, Disclosures about Segments of an Enterprise
and Related Information, for the year ended December 31, 1999. SFAS No. 131
established standards for reporting information about operating segments in
annual financial statements and requires selected information about operating
segments in interim financial reports issued to stockholders. It also
established standards for related disclosures about products and services, and
geographic areas. Operating segments are defined as components of the enterprise
about which separate financial information is available that is evaluated
regularly by the chief operating decision maker, or decision making group, in
deciding how to allocate resources and in assessing performance.

The Company develops, manufactures, markets and sells high technology dental
products, such as air abrasive equipment, lasers, curing lights and intra oral
cameras. The Company sells these products to national and regional dental
distributors in its four fundamental business segments: North America, Japan,
Europe and Other International. The reportable segments are managed separately
because selling techniques and market environments differ from country to
country. The remaining activities of the Company, which are reported as "Other",
include industrial, parts and accessories and royalty income.

The accounting policies of the business segments are consistent with those
described in Note 1. Operating results for North America, substantially all of
which is attributable to the United States, include the effects of the business
acquisitions, as described in Note 2. The Company's Chief Operating Decision
Maker evaluates segmental performance and allocates resources based on
operational earnings (gross profit less selling and marketing expenses).
