ITEM 1. DESCRIPTION OF BUSINESS

COMPANY DEVELOPMENT

American Technology Corporation ( the "Company") was incorporated in the State
of Utah on February 11, 1980 as Chasko, Inc. and on April 7, 1982 its name was
changed to American Technology Corporation. On June 19, 1992 the Company
redomiciled from the State of Utah to the State of Delaware. On July 14, 1992,
the Company completed a 1-for-5 reverse stock split resulting in 7,291,228
common shares, par value $.00001, being issued and outstanding after the reverse
split. The Company's shares trade in the over-the-counter market on the National
Association of Securities Dealers OTC Bulletin Board system under the symbol
"ATCO."

From its inception in 1980 to 1984 the Company was primarily engaged in the
development of a patented 2-speed long play cassette recorder ("X-TEN(R)"). On
September 30, 1984, the Company acquired 100% of the outstanding shares of
Norcom Electronics Corporation, which was engaged in development of patented ear
radio and ear-microphone 


                                       2
<PAGE>   3

technology. Both technologies feature small electronics for placement in or
around the entrance to the ear canal to perform desired functions. From 1984
through 1987, the Company was engaged in various licensing and development
activities with respect to the X-TEN, ear radio and ear-microphone technology.

In March 1988 the Company assigned certain ear-microphone technology to Norris
Communications, Inc. ("NCI") in return for 700,000 shares of NCI common stock
and a 1% royalty on gross sales resulting from the exploitation of certain
products using the ear-microphone technology ("EarPHONE"). The Company retained
its ear radio technology. The ear-microphone technology was subsequently sold by
NCI to JABRA Corporation ("JABRA") which is commercializing the EarPHONE for
cellular phone, computer, multi-media and other customer uses. See "Certain
Relationships and Related Transactions."

From 1988 to early 1992, the Company was inactive due to inadequate financial
resources. In early 1992 the Company was brought into good standing and
restructured to take advantage of new financing opportunities designed to allow
the Company to pursue development of its products and technologies. There were
no changes to management resulting from this reactivation.

Since the 1992 restructuring, Company operations have focused on developing its
various technology assets. The Company's address is 13114 Evening Creek Drive
South, San Diego, California, and its telephone number is 619-679-2114. Its
Internet site is located at www.atcsd.com.

BUSINESS

OVERVIEW
The Company is engaged in the development, manufacturing and marketing of
consumer electronic products and acoustic technologies. The Company's ear radio
technology was commercialized through the 1993 introduction of the FM ear radio
and the 1995 introduction of the AM ear radio. During fiscal 1997 substantially
all of the Company's revenues resulted from the manufacturing and marketing of
its "FM Sounds" FM digital scanning ear radio. The Company intends to introduce
new radio and related products and expand its ear radio distribution while
developing new technology assets.

The Company's HyperSonic(TM) Sound (HSS) reproduction technology has become its
primary business focus, although there can be no assurance the Company can
successfully exploit this new technology. HSS technology utilizes a new method
of sound reproduction -- sound is generated in the air using ultrasonic
frequencies, those above the normal range of hearing. A patents-pending process
creates an ultrasonic wave that interacts in mid-air to produce wide spectrum
audio. Since traditional loudspeaker system elements such as voice coils,
magnets, cones/diaphragms, crossover networks, baffles and speaker enclosures
are eliminated, management believes HSS technology offers higher quality sound
with less distortion while using less power, space, and weight and at a lower
cost. The sound produced by the HSS technology is also significantly more
directional over greater distances with less volume loss than traditional sound
reproduction methods thereby offering a number of application advantages to
users.

INDUSTRY BACKGROUND
The human ear is sensitive to the rate at which sound vibrations occur or
frequencies from about 20 Hertz (Hz) to 20,000 Hz (a Hertz is equal to one
vibration per second). A wide variety of loudspeakers are produced today to
recreate the range of hearing. These range from tweeters that attempt to
re-create the top end of the audio spectrum, to mid-range speakers, and woofers
to address the lower frequencies. Conventional loudspeakers are direct radiating
-- they are fundamentally a piston-like device designed to directly pump air
molecules into motion to create audible sound waves. Better sound quality and
low frequency (bass) reproduction is generally associated with larger and more
expensive speakers.

Since 1925, when C.W. Rice and E.W. Kellogg described basic, direct radiating
speaker parameters, there have been few fundamental changes in speaker design or
in the way electrical impulses are converted to sound. During this period,
electronics (receivers, amplifiers, tuners and recording and playback equipment)
have evolved from vacuum tubes to solid state digital circuits and recording
technology has progressed from analog grooves in records to digital coding on
compact discs that are read by a laser. Loudspeaker industry developments have
focused primarily on improving individual elements such as magnets, coils, cones
and enclosures. However, compared to the improvements in electronics, the
Company believes loudspeakers are still relatively inefficient in converting
electrical energy into acoustic energy and their design contributes to various
forms of sound distortion.

The loudspeaker market is an important segment of the electronics industry.
Loudspeakers are used in televisions, radios, telephones, computers,
automobiles, and a wide range of other consumer and industrial applications.
From miniature speakers in hearing aids to large home theater, public address
and concert sound systems, loudspeakers encompass a wide range in size, quality
and cost. The manufacture and sale of loudspeakers is highly competitive and

                                       3
<PAGE>   4

includes both large international consumer electronic companies and specialty
branded loudspeaker manufacturers. The Company believes the lack of fundamental
innovation and the diversity and size of the loudspeaker market presents an
opportunity to introduce new sound technology that will appeal to consumers and
be cost-effective for manufacturers.

HYPERSONIC SOUND STRATEGY
The Company's objective is to become a leader in developing, marketing and
licensing proprietary sound reproduction technologies and systems that address
large and expanding domestic and international consumer electronics markets. The
Company seeks to have its HSS technology become a significant alternative to
conventional loudspeakers in target market segments. The Company believes that
it is becoming increasingly difficult for manufacturers to differentiate their
sound reproduction products and a novel method of reproduction with new features
will find a receptive audience.

The Company's marketing of the HSS technology continues to evolve as a result of
market awareness, technical developments, changes in patent and protection
strategies and reactions from prospective users of the technology. Rather than
broadly licensing large market segments or industries, the Company is focusing
its efforts on original equipment manufacturers ("OEMs") desiring to implement
the HSS technology in specific products. The Company's strategy is to establish
business relationships with leading participants in various segments of the
electronics and sound reproduction markets. The Company believes this strategy
will enable it to take advantage of the superior financial resources,
technological capabilities, proprietary positions and market presence of these
companies in establishing and maintaining HSS technology in sound reproduction.

The Company also intends to implement a branding strategy to make HSS synonymous
with innovative, high-quality sound reproduction. The Company believes that
positioning itself as a licensor of the HSS technology and establishing
technology collaboration arrangements with manufacturers will facilitate the
rapid adoption of HSS technology. Key elements of the Company's strategy
include:

        1. Build on technical achievements to allow licensees to produce
        commercially viable products for consumers. The Company's new technology
        is in an early stage of development. The Company intends to rapidly
        convert its proof-of-concept demonstration into designs and materials
        that licensees can use to produce commercially viable sound reproduction
        systems to meet consumer demand across a variety of targeted market
        segments.

        2. Expand patent coverage. The Company has filed multiple initial patent
        applications worldwide and expects to continue to file amendments,
        continuations and additional patents as development progresses.
        Management believes the scope and breadth of its patents will be an
        important factor in the exploitation of HSS technology.

        3. Implement a segmented licensing approach. The Company has developed a
        segmented licensing approach to target individual fields of use for the
        HSS technology. Manufacturers of electronic components will be offered
        licenses to produce HSS-enabled electronic products and HSS emitters
        (specialized ultrasonic devices essentially taking the place of
        loudspeakers). The Company may sell circuit board level electronic
        components or an ASIC (Application Specific Integrated Circuit)
        containing necessary electronics to make electronic implementation
        simpler. The Company may also arrange for the production of and market
        customized ultrasonic materials to its specifications to be used in HSS
        emitters.

        4. Identify and determine market segment needs. The Company has
        identified and is focusing its licensing efforts on four initial fields
        of use (a) computers, monitors (b) high end televisions, (c) home
        theater/professional audio, and (d) communications. The Company is
        working with manufacturers in each of these fields of use to identify
        market requirements and customize HSS technology. The Company believes
        that its HSS technology can become an important competitive feature for
        manufacturers and can also enable such manufacturers to achieve premium
        price or premium margins for their products.

        5. Establish cross segment relationships to facilitate standards. The
        Company believes that successful implementation of HSS technology
        requires the cooperation of manufacturers of electronic components. The
        Company believes that developing standards for HSS-enabled electronics
        and ultrasonic HSS emitters will accelerate adoption of the technology
        across targeted fields of use. Therefore the Company is targeting
        long-term relationships with multiple entities to provide a competitive
        advantage in protecting the Company's market position.

        6. Support licensees and develop a market position. The Company intends
        to support its licensees with technical support and an ongoing research
        and development effort. The Company intends to require branding of HSS
        devices to create and build consumer awareness.

The Company's strategy is to develop strategic arrangements with manufacturers
in the targeted fields of use with limited exclusivity to accelerate
implementation and market introduction and to allow the selected manufacturers
to 


                                       4
<PAGE>   5

differentiate product offerings from competitors. The Company has not yet
entered into any strategic arrangements and there can be no assurance the
Company will be successful in implementing its strategy or exploiting its HSS
technology.

Although the Company anticipates generating a significant portion of its
revenues from licensing, the Company may also sell HSS materials or components.
The production and sale of HSS equipment may also accelerate market entry or
meet specialized market needs.

There can be no assurance that the Company can commercialize its HSS technology
nor be successful in implementing the above strategies. See "Business Risks."

HYPERSONIC SOUND TECHNOLOGY

Background and Stage of Development
The Company's HSS technology was invented by Elwood G. Norris, a director and
Chief Technology Officer of the Company, who manages the Company's research and
development and technical activities. Mr. Norris also invented the Company's ear
radio, Global Positioning System ("GPS") and Engine Plasma Displacement ("EPD")
technology for jet engine noise reduction. The Company acquired the basic
concepts of HSS technology (previously called the Sonic Generator technology)
from Mr. Norris in 1992. During fiscal 1996 and 1997, the Company devoted a
significant portion of its research and development activities on HSS
technology. In July 1996 the Company produced a laboratory proof-of-concept
demonstration capable of producing sound in the air using ultrasonics. In
October 1996 the Company produced a second generation portable demonstration
system with improved electronics. The portable system consists of a standard CD
player, an off-the-shelf amplifier modified by the Company, custom electronics
and modified commercial ultrasonic emitters. In September 1997 the Company
produced a portable stereo demonstration system and in October 1997, developed
test equipment for evaluation by selected companies interested in collaborating
on further development. During fiscal 1997 the Company's development efforts
also focused on significantly expanding the pending patents portfolio on HSS
technology and designing, developing and testing improved electronics and
ultrasonic emitters. The Company believes that custom ultrasonic emitters will
be required to produce a commercially viable system.

The Company is continuing to improve its proprietary electronics and is working
with multiple producers of ultrasonic devices to assist in developing custom
emitters to the Company's specifications. The Company believes, but there can be
no assurance, that it can have commercially acceptable designs and sources of
materials for use by licensees during fiscal 1998. However, the development of
the Company's HSS technology has taken longer than anticipated by the Company's
management and could be subject to additional delays. There are inherent risks
in new technology development, many beyond the control of management. See
"Business Risks."

In May 1997 the inventor of the HSS technology, Mr. Norris, was awarded the 1997
Discover Magazine Award for Technical Innovation in the Sound category for the
Company's HSS technology. Winners in a total of eight categories were selected
from over 4,000 entries. The annual awards are designed to recognize and promote
new technological innovations and the winners are selected by an expert panel of
judges. Winners were also featured in the July issue of Discovery magazine. In
November 1997 HSS technology won a Popular Science 1997 "Best of What's New
Award" from among thousands of new products. These awards and recognition have
provided broad marketing exposure for the HSS technology to prospective users.
HSS technology has also been featured in over 30 journal articles providing
additional marketing exposure.

The Company continues to devote significant resources in preparing and filing
patent applications related to various aspects of the HSS technology. A total of
eleven HSS technology patents have been filed and others are in various stages
of preparation.

Technology Description
HSS technology is partially based on a phenomenon in music known as Tartini
tones first noted by Giuseppe Tartini, an 18th century composer. When two sound
tones are positioned relatively close together and are sufficient in volume,
then two new tones appear, one is the sum of the original tones and one is the
difference. In 1856, H. von Helmholtz, a German physiologist and physicist,
published the results of his combination tone experiments proving the effect
resulted from the non-linearity of air. He also developed descriptive
mathematics which remain valid today. Although others have experimented with
these principles in the past, the Company believes it has created novel and
proprietary methods to efficiently use this concept to produce sufficient sound
volume and quality capable of being commercially exploited. The Company's
breakthroughs and its process are the subject of multiple pending patents.

Mr. Norris, who has previous patents in the fields of ultrasonics and audio,
applied aspects of the electrical concept of mixing multiple electrical signals
to produce new audio by-products. HSS technology employs a method where


                                       5
<PAGE>   6

ultrasonic frequencies are created electronically using proprietary techniques
to carry intelligence (e.g. music, voice) and these ultrasonic frequencies are
then emitted into the air using an ultrasonic emitter. Since the audible sound
is created in the air, sound does not appear on the surface of the ultrasonic
emitter (a significant departure from a loudspeaker) but is actually created
within the beam of ultrasonic energy being emitted. Accordingly, if the beam is
directed towards a wall, the sound emanates from the surface and if the beam is
directed to a person the sound emanates from the person. This directionality
allows sound to be manipulated in space or diffused from a surface in a wide
variety of ways to produce desired effects. The sound also does not dissipate
over distance as it does with traditional speakers, providing greater volume at
selected distant points with less energy.

The Company's use of ultrasonic frequencies to carry intelligence is compatible
with existing recording and transmission technology. The generation of the
ultrasonic frequencies employed by HSS technology requires modification to
existing electronic amplifiers (radios, televisions, telephones, etc.). However,
since HSS technology requires less wattage (similar to a tweeter requiring less
wattage than a sub-woofer) to reproduce sound, the Company believes electronic
products that are HSS-enabled can be produced at the same or lower cost than
current systems and in a smaller size. The Company has designed and is
continuing to improve electronic specifications to be used to enable electronic
devices to produce the ultrasonic output (as compared to audio output in a
traditional system) necessary to drive HSS ultrasonic emitters.

HSS technology uses ultrasonic emitters (transducers which convert electrical
energy to high frequency acoustical energy). Certain crystals, and ceramics and
other materials, known as piezoelectric elements, produce high frequency
movement when voltage is supplied. These piezoelectric elements are used to emit
ultrasonic energy in applications such as sonar, ultrasonic cleaning, industrial
inspection and medical ultrasound. Such ultrasonic devices are incapable of
producing frequencies in the audible range. However, the Company has developed
the ability to use such devices (in lieu of loudspeakers) to emit a
custom-generated ultrasonic wave with the proper difference frequency
characteristics to produce audible sound in the air. The Company believes its
ultrasonic emitters will be designed and configured in a variety of designs,
shapes and sizes to produce desired effects in commercial applications.

Ultrasonics are employed in a wide variety of medical applications where it is
directly coupled to the body rather than air. The Company's technology uses
relatively small amounts of ultrasonic sound energy which dissipates or is
absorbed rapidly in the air. The Company employs frequencies above those that
may be harmful to pets but within those used by medical devices directly
coupling to the body to image fetuses and the brain. The Company believes that
the frequencies and amount of energy employed in the HSS technology is harmless.
The Company also believes the emission of such frequencies is not subject to
governmental regulation.

The Company believes its HSS technology, comprised of the combination of
proprietary electronics and custom ultrasonic emitters, will offer the following
advantages:

        -  Coverage of the entire audible range (20 Hz to 20,000 Hz) with one
           small device no woofer, mid-range and tweeter combination and no
           crossover network to divide the signal amongst such devices
        -  Sound quality that is not dependent on the size of the emitting face
           or speaker enclosure
        -  Elimination of speaker enclosures and their cost and bulk 
        -  Reduction of the effect of room acoustics on sound quality 
        -  Small size and low weight as compared to conventional speakers 
        -  Improved phase coherency (frequency time alignment) 
        -  Reduced distortion 
        -  Lower power requirement and greater efficiency 
        -  Ability to manipulate or selectively position or diffuse the source
           of sound
        -  Ability to deliver a beam of sound over greater distances 
        -  Elimination of magnets, their weight and adverse effects on video
           monitors
        -  Elimination of feedback in professional applications

There can be no assurance these advantages can be successfully implemented
commercially.

Target License Market Segments
The Company has targeted four initial fields of use which include computers and
monitors, high end televisions, home theater/professional audio systems and
communications. As of the date of this report the Company has not finalized the
details of its proposed licensing terms and conditions and has not entered into
any license agreements on HSS technology. However, the Company has commenced
discussions with manufacturers in each of the primary segments. The Company
recently demonstrated the application of HSS technology in a personal computer
for a prospective customer to demonstrate the advantages of directed sound,
small size and high sound quality. Management is encouraged by the technical and
marketing interest in its new sound technology and is pursuing its targeted
implementation strategy.

The market for computer sound, primarily multimedia applications, is growing
rapidly. According to market researcher The Yankee Group, 1996 multimedia
equipped desktop personal computer worldwide shipments were 38.8 million units,
with a total market value of $90 billion. There is also a growing demand for
improved sound in notebook and other small computers with worldwide annual sales
exceeding 70.86 million units in 1996 according to Dataquest. An increasing
number of computer video monitors are incorporating sound. In 1996 over 65
million monitors were sold, according to Dataquest. In addition to OEM computer
sound markets, there is a growing aftermarket for computer speakers. Major
suppliers of computer sound equipment include OEM's such as Apple, IBM, Packard
Bell, Compaq and others and manufacturers such as JBL, Sony, NEC, Mitsubishi,
Phillips, Yamaha, Bose, Panasonic, Foster and others.

The Company believes limitations in size, sound quality and cost are critical
factors in the computer sound market. The Company expects HSS technology to
offer size, cost and quality advantages to manufacturers and consumers in this
large and growing market.

High end televisions and home theater systems are growing segments of the
consumer electronics market. Home theater audio systems include component and
rack audio systems for the home as well as specifically targeted home theater
systems. Professional audio systems include systems used by studios and other
professionals in the creation or production of audio and video material. The
Company intends to focus initially on manufacturers in the mid to high-end range
of these segments. Home theater and large screen televisions are expected to
experience continued growth from the introduction of the high-capacity DVD
(digital versatile disc). Over 14 million televisions 19" and larger were sold
in the U.S. in 1996 according to the Consumer Electronics Manufacturers
Association (CEMA). In addition, almost 1 million projection televisions were
sold in the same period. According to the Electronic Industries Association
(EIA), households with the equipment to enjoy home theater in 1996 included
approximately 15 million U.S. homes.

EIA also estimates that U.S. factory sales of home theater and aftermarket
loudspeakers exceeded $944 million in 1996. Manufacturers in these segments
include major international consumer companies, such as Sony, AIWA, Phillips,
Samsung, Mitsubishi, Toshiba, Sanyo, Sharp, JVC and others, and specialty audio
component manufacturers such as Carver Corporation, Marantz, NAD and others.

The market for professional audio systems is also growing. The domestic U.S.
market for public address systems exceeded $447 million in 1995 according to EIA
and the market for other professional equipment including sound modules,
synthesizers, digital pianos, signal processing equipment and other products are
experiencing growth.

The Company believes its HSS technology will offer the home audio/video and
professional markets improved full-spectrum sound source with less distortion
and less room-acoustic interference. The ability to place and manipulate sound
in a room without large multiple speakers is expected to be attractive to
consumers. The lack of feedback is an important feature for professionals.

The communications market for HSS technology includes all types of telephones,
answering machines, speaker and conference phones and audio and video
conferencing systems. The U.S. market for telephones and answering machines was
worth $3.5 billion in 1996, according to the Polk Company. Leading manufacturers
include AT&T (Lucent and the new Lucent/Phillips joint venture), Motorola,
Ericsson, General Electric, Nokia, and Uniden. In addition, audio and video
conferencing equipment sales exceeded $4.2 billion in the North America in 1996
according to the International Teleconferencing Association. Leading vendors in
this industry include Picturetel, Sony, Intel and Polycom.

Other HSS Market Opportunities
While the Company's strategy is to focus on licensing to the above market
segments, HSS technology is expected to have utility in diverse applications
including military applications, portable consumer electronics, hearing aids,
headphones, cinema/theater, public address and outdoor sound systems, use with
noise cancellation systems, and many other applications. The Company also
believes there is a significant opportunity for HSS-enabled devices designed to
retrofit existing stereo equipment to provide theater-like sound. The Company
may license, design, develop, manufacture and/or distribute products for these
or other specialized applications.

EAR RADIO TECHNOLOGY

Product Description
The Company's patented ear radio technology allows the placement of a fully
operational radio device adapted in size and configuration for placement and
retention at the entrance of the ear canal.

FM and AM versions of the ear radio utilizing this technology have been
developed and are manufactured for and marketed by the Company. The FM ear radio
measures 1/2" by 1-1/2" by 1/4", utilizes approximately 40 transistors, features
digital scanning touch-tuning and weighs less than 1/4th ounce. The AM ear radio
measures 1-1/4" by 5/8" by 


                                       7
<PAGE>   8

3/8" and weighs less than 1/4th ounce and features sound quality comparable to
much larger radios. The Company produces standard and Japanese frequency FM
radios and standard AM radios. The radios come in a variety of colors and are
packaged for either retail or bulk shipment. The radios generally retail for
$12.95 to $29.95 depending on the outlet and the accessories included.

FM and AM ear radios accounted for substantially all of the Company's revenues
during fiscal 1997 during which it sold approximately 107,000 ear radios to
customers.

Further applications of this technology have been identified, but not yet
produced, including fixed-frequency AM, FM or TV band units for use in special
station or program promotions, and fixed-frequency AM or FM units for use in
specialized local broadcast environments for various events.

The Company anticipates that it will be required to update its ear radio designs
and packaging from time to time to meet market expectations for performance and
packaging. The Company has developed an improved FM ear radio but management has
not established a date for introduction. The Company is currently selling to
customers from inventory and has not yet determined product plans for fiscal
1998. The current assembly contract has expired and the Company has not decided
where or if to continue ear radio production. See "Assembly and Production."

The Company has also designed and developed a mini-headphone radio (HeadGear)
scheduled for introduction by mid-1998. Incorporating ear radio technology, the
HeadGear is smaller than similar headphone radio products currently on the
market. The intended retail price range is $29.95 and up. The Company has filed
one patent application for this product. There can be no assurance this product
can be introduced to market or that it will be successful.

Management is also seeking compatible products and accessories developed by
others for distribution. There can be no assurance the Company can obtain rights
to manufacture and/or distribute any other products or accessories.

The Company is the holder of patent number 4,539,708, granted September 3, 1985
and patent number 5,313,663, granted May 17, 1994 which relate to AM, FM, VHF
and UHF frequency bands, as well as IR (Infrared) frequency bands. See
"Intellectual Property Rights and Proprietary Information."

Marketing Strategy
The Company's existing FM and AM ear radios and products and accessories under
development or acquired in the future are targeted for the portable audio
products segment of the consumer electronics market. According to CEMA, the U.S.
wholesale portable radio market in 1996 was approximately $42 million. The
Company's marketing strategy is to wholesale its ear radios to a variety of
organizations and companies already established to market and distribute the
products to retailers and consumers. This strategy is designed to allow the
Company to focus its efforts on manufacturing and new product development while
limiting marketing and distributing personnel and associated costs. However,
this strategy also limits the Company's ability to control and direct the
marketing, distribution and end-pricing of its product.

To date, the Company has focused on four primary market segments for ear radio
marketing and distribution:

        -  Retail outlets - The Company directly, and also through established
           manufacturer representatives, promotes its products to local,
           regional and national retail distributors such as electronics stores,
           drug stores, computer stores and other retailers.

        -  Catalog distribution - The Company's personnel contact catalog
           companies directly and through third-party agents. To date the
           Company's radios have been illustrated and offered in a diverse range
           of catalogs.

        -  Television - The radios have been displayed and sold by various
           television marketers. The Company's marketing plan includes pursuing
           additional television outlets for its products.

        -  Premium/Incentive/Specialty - The Company targets corporate and other
           organizations to use the radios as premiums, incentives, prizes and
           for promotions. The radios are designed for logo placement and use in
           such promotions. The Company has attended premium/incentive trade
           shows as well as initiated direct contact with large users of prizes
           and premiums. Specialty applications would also include fixed
           frequency radios for use by a specific radio station or sports team
           or other program interested in featuring their activity or
           organization.

The Company has two full-time marketing personnel assigned to ear radio
marketing and sales activities. The Company had seventeen independent sale
representatives in the U.S. and Canada at September 30, 1997. The Company also


                                       8
<PAGE>   9

employs international distributors from time to time. However due to foreign
competition and a marketing focus on domestic sales, export sales in fiscal 1997
were only 2% of sales versus 27% in fiscal 1996.

Assembly and Production
The Company primarily uses subcontract assembly companies to produce ear radios
from components and subassemblies purchased from others, some of which are
manufactured to the Company's specifications. The Company tests, packages and
ships the ear radios from its San Diego, California location but may subcontract
some of these steps in the future. The Company performs limited assembly work
from time to time. The Company performs its own engineering and quality control.

The Company believes there are secondary suppliers of components and
subassemblies available such that it is not reliant on one supplier, although
delays could result should the Company be required to change suppliers of longer
lead time components or subassemblies. Any significant delays in obtaining
components from existing or secondary suppliers through supplier changes or from
component shortages, which are common to the electronics industry, could have a
material adverse impact on the Company's results of operations.

In July 1995 the Company, through the services of its agent Mitsui U.S.A., Inc.,
entered into a subcontract manufacturing agreement with Zhuhai Huasheng
Enterprise Group Co., Ltd. of mainland China to produce FM ear radios. This
relationship resulted in added capacity and reduced costs. This agreement
terminated in July 1997 and the Company is currently reviewing its future plans
for ear radio product production at this or other assembly sites. The Company
believes that there are a number of electronic product subcontract assembly
companies located in North America and overseas that are qualified to produce
the Company's electronic products should the Company change assembler or should
a future assembler be unable or unwilling to produce, however any disruption of
supply could cause additional costs and delays and could have a material adverse
impact on the Company's results of operations.

The Company produces both to meet orders and for inventory for future orders.
Most orders have generally been filled within forty-five days, however any
future large orders could exceed the Company's production and financial capacity
and adversely affect the Company's operations. Because the Company's policy is
to fill orders promptly, the Company does not maintain and does not expect in
the future to maintain a significant backlog of sales on its ear radio products.

PORTABLE GPS TECHNOLOGY, EPD TECHNOLOGY AND OTHER TECHNOLOGIES AND INVESTMENTS

Portable GPS Technology
In late 1994 the Company innovated a proprietary method of tracking persons and
objects utilizing GPS technology. A substantial portion of the Company's 1995
research and development budget was expended in furthering this technology. The
Company has designed a portable device as a simple solution to (1) finding
another person or object or (2) finding a known location. It employs GPS
technology but doesn't require complicated longitude/latitude readouts, mapping
software or recording and storing of previous locations and movements as used in
most portable GPS devices. The Company has produced a proof-of-concept
demonstration system utilizing the GPS technology.

The field of GPS technology involves a large number of companies with
substantial resources devoting significant funds to research and development and
launching many new products. It is a very competitive field with frequent
introductions of new features and rapidly declining prices. With the nature of
this intense competition in mind, the Company has taken extended steps in its
attempts to protect this product concept, including the filing of two U.S.
patent applications and reviewing the applications with a U.S. patent examiner
specializing in GPS technology. Patent number 5,689,269 was granted November 18,
1997 and one patent is pending. There can be no assurance the pending patent
will issue or that, if issued, that it or the issued patent will provide
meaningful protection from competition.

With the current emphasis on HSS technology, the Company has postponed further
development on its GPS technology pending an evaluation of patent protection
that may be available and further market evaluation due to significant
competition and the rapidly changing nature of the GPS equipment market. The
Company believes, but can make no assurance, the remaining pending patent will
issue during the next fiscal year, however there can be no assurance thereof.
The ultimate claim set allowed is expected to be a determining factor on future
activity with respect to this technology. The Company believes that certain
features of its pending patent, if allowed, may be licensable to the GPS
industry.

EPD Technology
The Company has filed an initial U.S. patent application regarding a new method
and system for reducing noise in jet engines, the EPD technology. This
technology, invented by Mr. Norris, relates to canceling acoustic waves produced
by a jet engine by stimulating a plasma within the engine to propagate an
acoustic interference wave. Mr. Norris has previously performed rudimentary
experiments on this technology, however the Company has not yet developed a


                                       9
<PAGE>   10

proof-of-concept device or demonstration. There can be no assurance that the
Company's concepts will function as theorized or that any practical product or
technology can ever result from the concepts. In addition, the Company has
performed only limited competitive research and there can be no assurance that
the concepts innovated by the Company are new or unique or that they are
functionally better than existing and proposed methods for jet engine noise
reduction.

The Company's strategy is to develop a proof-of-concept demonstration of the EPD
technology and seek a collaborative arrangement to further develop this
technology. Management has not developed a timetable for this project nor
identified personnel for further development. Although management believes there
is a significant market for an improved system for jet engine noise reduction,
there can be no assurance when or if the EPD technology can be exploited by the
Company.

Other Technologies
The Company has other technology and product concepts in early stages of
development. There can be no assurance that these concepts will develop into
viable research projects nor that the Company will have the personnel and
financial resources to develop additional technologies.

Investment in Norris
At September 30, 1997, the Company held 225,300 common shares (less than 1%) of
Norris Communications Inc. (NCI), a San Diego-based OTC Bulletin Board-quoted
company engaged in the development, manufacture and marketing of electronic
products. These shares remain from the 700,000 shares received by the Company in
1988 from the sale to NCI of a newly formed subsidiary (now JABRA) that owned
the Company's ear-microphone technology. See "Certain Relationships and Related
Transactions." These shares had a market value of approximately $29,000 at
September 30, 1997.

By agreement dated October 31, 1997, the Company sold and canceled its 1%
royalty interest on gross sales of JABRA's EarPHONE technology products
incorporating a wireless receiver to JABRA for $15,000. There was no assurance
of any future royalties.

CUSTOMERS
For the fiscal year ended September 30, 1997, three customers accounted for 57%
of the Company's sales. Target Stores, Inc., CR McMullen Co., and Eddie Bauer
accounted for approximately 30%, 14% and 13% of sales, respectively, with no
other single customer accounting for more than 10% of sales.

The Company expects that it will continue to rely on a number of large
individual customers for future revenues and the loss of any customer could have
a material adverse effect on the Company's financial condition and results of
operations.

COMPETITION
The Company faces competition from a large number of international manufacturers
of consumer electronic and audio equipment products. Consumer tastes and demand
can change quickly.

HyperSonic Sound Technology
The Company has made substantial inquiry and search but is not aware of any
previous or other sound reproduction system that has successfully employed the
concepts similar to those developed by the Company. Although others have
attempted to use the combination tone concept to produce sound, to the knowledge
of the Company, none have been able to produce sufficient sound volume and
quality to make a commercially viable system.

Although most loudspeakers are of the direct radiating type, there have been
many attempts to innovate new methods of sound reproduction to overcome
limitations of traditional loudspeakers. For example direct radiating flat-panel
loudspeakers overcome some of the size limitations, but they are generally
limited by sound quality and frequency range. There can be no assurance that
alternate technologies and systems have not been developed, or that such systems
may currently be in development or will be developed by others in the future
that would be directly competitive with the Company's HyperSonic Sound
technology.

The Company's method of sound reproduction will also compete with existing
loudspeakers. In addition to the companies described above in "Target License
Market Segments," many who currently provide loudspeakers with their consumer
electronic products, the Company will also compete with branded loudspeaker
manufacturers including Bose Corporation, JBL, Harman International (Infinity
and Epicure), International Jensen (Acoustic Research and Advent), Polk Audio,
Boston Acoustics, Klipsch, Yamaha and a host of others. Such competitors have
substantially greater financial, technical and marketing resources than the
Company and have existing proven technology and products, 


                                       10
<PAGE>   11

marketing data, customer relationships and distribution channels. There can be
no assurance that the Company's HSS technology, if implemented commercially,
will be competitive in the entrenched loudspeaker market.

The Company believes that its success will be dependent upon creating
relationships with electronic equipment manufacturers by providing them the
ability to differentiate their products. Specifically, the manufacturers could
offer improved sound in a small light-weight unit at competitive prices with
additional advantages such as the ability to spatially orient sound in novel
ways. The Company believes it will compete on the uniqueness of its proprietary
technology and designs, system features and price, ease of use, quality of
marketing and ability to identify and meet consumer needs. There can be no
assurance that based on these factors the Company can be competitive with
existing or future products, technologies or services of its competitors.

Ear Radio Products
The Company's ear radio products compete directly with a number of miniature
radios such as pocket and credit card-size radios. Most of the Company's
competitors have greater financial, manufacturing and marketing resources and
can command more retail and consumer exposure than that of the Company. Barriers
to entry by new competitors are not significant and new competitors in consumer
electronics are continually commencing operations. The technology of electronics
and electronic components, features and capabilities is also rapidly changing,
in many cases rapidly obsoleting existing products and technologies.

The Company believes that its ear radio is a one-of-a-kind product featuring a
radio entirely placed at the entrance to the ear canal. This feature, along with
the quality of each radios' sound and the FM's digital touch tuning, are
believed to be the most important competitive features important to customers.
The Company believes that its patents provide it some protection and act as a
barrier to entry into the U.S. from foreign competitors offering a similar radio
device, however the Company recognizes patents are subject to loss,
circumvention and other risks. See "Intellectual Property Rights and Proprietary
Information."

GOVERNMENT REGULATION
The Company is subject to regulation by federal, state and local governmental
authorities in connection with its assembly and production operations. The
Company's electronic products are also subject to various regulations and are
required to meet the specifications of agencies such as the Federal
Communications Commission (the "FCC"). The Company believes it is in substantial
compliance with all applicable regulations, and that it has all material
governmental permits, licenses, qualifications and approvals required for its
operation.

The Company does not believe its ultrasonic emitters, which emit ultrasonic
waves into the air rather than electromagnetic waves, are the subject of
existing governmental regulation. However there can be no assurance that
interpretations of existing regulations or imposition of new regulations could
not have an adverse impact on the Company's proposed commercialization of HSS
technology.

The Company does not believe it is materially affected, nor does it expect to be
materially affected, by the costs and effects of compliance with environmental
laws.

INTELLECTUAL PROPERTY RIGHTS AND PROPRIETARY INFORMATION
The Company operates in an industry where innovations, investment in new ideas
and protection of its resulting intellectual property rights are important to
success. The Company relies on a variety of intellectual property protections
for its products and technologies, including patent, copyright, trademark and
trade secret laws, and contractual obligations, and pursues a policy of
vigorously enforcing such rights.

The Company currently holds two issued U.S. patents, #4,539,708 granted
September 3, 1985 and #5,313,663 granted May 17, 1994, on the ear radio
technology. The Company holds U.S. patent #5,689,269 granted November 18, 1997
and has one patent pending on its GPS technology. The Company has one patent
pending on its EPD technology, one patent pending on the HeadGear product, and
eleven patents pending on its HSS technology. The Company is currently preparing
and intends to file additional HSS technology patent applications.

The Company has an ongoing policy of filing patent applications to seek
protection for novel features of its products and technologies. Prior to the
filing and granting of patents, the Company's policy is to disclose key features
to patent counsel and maintain these features as trade secrets prior to product
introduction. There can be no assurance that any additional patents on the
Company's products or technology will be granted.

In addition to such factors as innovation, technological expertise and
experienced personnel, the Company believes that a strong patent position will
be important to compete effectively through licensing in the sound reproduction
industry. The Company is investing significant management, legal and financial
resources toward HSS technology patents. The electronics industry is
characterized by frequent litigation regarding patent and other intellectual
property rights. 


                                       11
<PAGE>   12

Numerous patents in electronics and sound reproduction are held by others,
including academic institutions and competitors. Although the Company is not
aware of any existing patents that would inhibit its ability to license the HSS
technology, there can be no assurance that others will not assert claims in the
future. While sometimes licenses to third-party technology are available, there
can be no assurance thereof or that such claims, with or without merit, would
not have a material adverse effect on the Company.

The validity of the Company's existing patents have not been adjudicated by any
court. Competitors may bring legal action to challenge the validity of the
Company's patents or may attempt to circumvent the protection provided by those
patents. There can be no assurance that either of such activities by competitors
would not be successful. The failure to obtain patent protection or the loss of
patent protection on the Company's technology, or the circumvention of the
Company's patents, when and if granted, by the Company's competitors could have
a material adverse effect on the Company's ability to compete successfully in
its business.

The Company also files for tradename and trademark protection when appropriate.
Marks for which the Company has registrations or applications to register in the
U.S. or foreign countries include HyperSonic and HSS. There can be no assurance
any degree of protection will be granted, or that if granted, that tradenames or
trademarks can be successfully defended or protected.

The Company's policy is to enter into nondisclosure agreements with each
employee and consultant or third party to whom any of the Company's proprietary
information is disclosed. These agreements prohibit the disclosure of
confidential information to anyone outside the Company, both during and
subsequent to employment or the duration of the working relationship. There can
be no assurance, however, that these agreements will not be breached, that the
Company will have adequate remedies for any breach or that the Company's trade
secrets will not otherwise become known or be independently developed by
competitors.

RESEARCH AND DEVELOPMENT COSTS
For the fiscal years ended September 30, 1997 and 1996, the Company spent
$566,288 and $160,934, respectively, on research and development. Future levels
of research and development expenditures will vary depending on the timing of
further new product development and the availability of funds to carry on
additional research and development on the Company's currently owned
technologies or in other areas.

EMPLOYEES
At November 1, 1997 the Company in addition to its four executive officer
employees, employed sixteen persons, including four part-time employees. Of such
employees, one person was engaged in purchasing, five in engineering/quality
control, one in production management, two in general/administrative and three
in marketing and sales. The Company also employs or leases assembly personnel
from time to time on an as needed basis and uses outside consultants for various
services.

The Company has experienced no work stoppages and is not a party to a collective
bargaining agreement. The Company believes its relations with its employees are
good.

ITEM 2. DESCRIPTION OF PROPERTY.
During most of fiscal 1997, the Company's research, assembly and shipping and
office facilities were subleased under a $2,000 monthly sub-lease agreement
which expired in January 1997 with an affiliated corporation NCI, and thereafter
was month to month until July 1997. On July 11, 1997, the Company entered into a
three year lease located at 13114 Evening Creek Drive South, San Diego,
California. To meet the credit requirements of the landlord, both the Company
and NCI entered into a joint lease agreement for approximately 12,925 square
feet with aggregate monthly payments of $13,830 inclusive of utilities and
costs. The Company is occupying approximately 7,500 square feet of the jointly
leased office space with its share of monthly payments being approximately
$8,000.

The Company believes this facility is adequate to meet its needs for the next
twelve months given management's current plans. However should the Company
expand its operations, it may be required to obtain additional space or
alternative space. The Company believes there is adequate availability of office
space in the general vicinity to meet its future needs.

ITEM 3. LEGAL PROCEEDINGS.
The Company is not a party to any legal proceedings.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.
No matter was submitted during the fourth quarter of the fiscal year to a vote
of security holders.

dividend on its Common Stock and does not expect to pay one in the foreseeable
future.

RECENT SALES OF UNREGISTERED SECURITIES
The following is a description of equity securities sold by the Company during
the year ended September 30, 1997 that were not registered under the Securities
Act:

        1. The Company issued a Stock Purchase Warrant to Renwick Corporate
           Finance, Inc. ("Renwick") dated February 5, 1997 exercisable to
           purchase 90,000 shares of Common Stock at $5.00 per share until
           February 5, 2000. The Company expensed $33,300 as the value assigned
           to consulting services in connection with this Stock Purchase
           Warrant. The issuance was exempt by reason of Section 4(2) of the
           Securities Act of 1933, as amended (the "Act") in reliance on the
           private nature of the transaction, restrictions on transfer and based
           on representations of Renwick.

        2. On March 25, 1997 the Company completed the private offering and sale
           for cash of an aggregate of $1,000,000 of unsecured 6% Convertible
           Subordinated Promissory Notes due March 1, 1999 ("Notes") to sixteen
           private investors (eleven accredited U.S. investors and five foreign
           investors). The securities were sold by the Company without an
           underwriter. The principal and interest amount of each Note is
           convertible on one or more occasions into shares of Common Stock, at
           a price which is the lower of (i) $3.50 per share or (ii) 85% of five
           days market price prior to conversion but not less than $2.50 per
           share or (iii) for any conversions on or after March 1, 1998 the
           average of the closing bid prices for the prior thirty days but in no
           event less than $1.00 per share. The Notes may be called by the
           Company for conversion if the market price exceeds $9.00 per share
           for ten consecutive days and certain conditions are met. Each
           purchaser was granted a warrant to purchase 50 common shares of the
           Company at $5.00 per share until March 1, 2000 ("Warrant") for each
           $1,000 of Notes purchased. The Warrants are exercisable, in the
           aggregate, into 50,000 shares. These securities were offered and sold
           without registration under the Act, in reliance upon the exemption
           provided by Regulation D thereunder and an appropriate legend was
           placed on the Notes and Warrants. The Company filed a registration
           statement, which became effective on 


                                       13
<PAGE>   14

           May 28, 1997, on shares of Common Stock issuable on conversion of the
           Notes and on exercise of the Warrants. Net proceeds from the sale of
           the Notes was approximately $950,000.

        3. On August 25, 1997 the Company completed the private offering and
           sale for cash at $10.00 per share a total of 350,000 shares of Series
           A Convertible Preferred Stock, par value $.00001 ("Preferred Stock")
           to eight institutional and three accredited individual investors
           ("Preferred Shareholders") for an aggregate of $3,500,000. The
           securities were sold by the Company without an underwriter. The
           dollar amount of Preferred Stock, increased by $.60 per share of
           Preferred Stock per annum and subject to other adjustments, is
           convertible on one or more occasions into shares of Common Stock at a
           conversion price which is 85% of the average of the closing bid
           prices of the Company's Common Stock each day for the five trading
           days immediately preceding the date of conversion provided that in no
           event shall such amount to be multiplied by 85% be less than $3.00
           per share or greater than $5.75 per share. The shares of Preferred
           Stock may be called by the Company for conversion if the common stock
           market price exceeds $14.00 per share for ten days and certain
           conditions are met. The Preferred Stock is subject to mandatory
           conversion after one year, subject to certain conditions. Each
           purchaser was granted a warrant to purchase 500 common shares of the
           Company at $7.50 per share until August 1, 2000 ("Warrant") for each
           1,000 shares of Preferred Stock. The Warrants are exercisable, in the
           aggregate, into 175,000 shares. These securities were offered and
           sold without registration under the Act, in reliance upon the
           exemption provided by Regulation D thereunder and an appropriate
           legend was placed on the Preferred Stock and Warrants. The Company
           filed a registration statement, which became effective on September
           30, 1997, on shares of Common Stock issuable on conversion of the
           Preferred Stock and the Warrants. Net proceeds from the sale of the
           Preferred Stock was approximately $3,321,000.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

OVERVIEW
From 1988 to early 1992 the Company was inactive. In early 1992 the Company
commenced its current business activities. Although the Company owns several
technologies, initial efforts concentrated on developing and producing FM ear
radios beginning in September 1993 and the AM ear radios beginning in July 1995.

The Company is focusing its primary efforts on completing development and
commercializing its HSS technology and expanding ear radio and related product
distribution.

Demand for the Company's ear radio products is subject to significant month to
month variability resulting from the limited market penetration achieved to date
by the Company. Initial sales have been concentrated with a few customers and
there can be no assurance of future orders from these or new customers. The
markets for the Company's products and future products and technologies are
subject to rapidly changing customer tastes and a high level of competition.
Demand for the Company's products is influenced by demographic trends in
society, marketing and advertising expenditures, product positioning in retail
outlets, technological developments, seasonal variations and general economic
conditions. Because these factors can change rapidly, customer demand can also
shift quickly. The Company may not be able to respond to changes in customer
demand because of the time required to change or introduce products, production
limitations and because of limited financial resources. For fiscal 1998 the
Company is also evaluating plans for ear radio and related products and the
choices made may impact future results. The Company's current FM radio off-shore
production agreement has expired and the Company has not yet determined where,
when or if it will produce additional FM radios for sale.

The HSS technology has not been developed to the point of commercialization.
There can be no assurance that a commercially viable system can be completed due
to the inherent risks of new technology development, limitations on financing,
competition, obsolescence, loss of key technical personnel and other factors
beyond the Company's control. The Company has not generated any revenues from
the HSS technology to date, and has no agreements or arrangements providing any
assurance of revenues in the future. The Company's various development projects
are high risk in nature. Unanticipated technical obstacles can arise at any time
and result in lengthy and costly delays or result in determination that further
development is unfeasible. There can be no assurance of timely completion of
commercially viable HSS technology or that if available that it will perform on
a cost-effective basis, or that if introduced, it will achieve market
acceptance.

The future of the Company is largely dependent upon the success of the HSS
technology or the development of new technologies. There can be no assurance the
Company can introduce any of its technologies or that if introduced they will
achieve market acceptance sufficient to sustain the Company or achieve
profitable operations. See also "Business Risks."

RESULTS OF OPERATIONS
Net sales for the fiscal year ended September 30, 1997 (fiscal 1997) were
$967,408, a 4% increase over sales of $933,643 for the prior fiscal year.
Substantially all revenues for both years were from ear radio sales. Commencing
in fiscal 1996, the Company encountered foreign-based competition for its FM ear
radio which due to the Company's U.S. patent had a greater impact on foreign
sales. The Company has taken and expects to continue to take actions to preclude
the sale of infringing radios in the U.S. The Company also responded to
increased competition by (1) contracting for off-shore assembly to reduce
production costs and (2) reducing prices to make the ear radios attractive to
large chain retailers. The improved sales results in fiscal 1997 include sales
to several large chain retailers, which sales are highly seasonal. The foreign
competition dramatically reduced foreign sales in fiscal 1997, which accounted
for 27% of sales in fiscal 1996 and only 2% of sales in fiscal 1997.

During fiscal 1996 management changed to off-shore assembly of the FM ear radio,
resulting in reduced per unit costs, working capital requirements and increased
capacity. However, reliance on off-shore assembly imposes certain risks,
including delays, shortages and quality issues. The Company's assembly agreement
off-shore has expired and the Company has not elected to renew the agreement.
The Company is evaluating its ear radio and related consumer product offerings
for fiscal 1998 with the goal of expanding revenues from additional products
developed internally (such as HeadGear) and obtaining distribution rights to
compatible products. In the meantime the Company is continuing to sell FM ear
radios from inventory and believes, should it elect to do so, that it could
obtain a domestic or off-shore assembler for the FM ear radio.

The Company was successful in fiscal 1997 in adding new sales representatives
and obtaining new ear radio accounts but at reduced unit prices. Although unit
ear radio sales increased 19% to 107,000 units, dollar sales increased only 4%
due to reduced average unit prices. The Company's sales are subject to
significant month to month and quarter to quarter variability based on the
timing of orders, new accounts, lost accounts and other factors. The Company's
sales are affected by a variety of factors including seasonal requirements of
customers. The Company's is also exposed due to its reliance on a limited number
of customers.

Cost of sales for the year ended September 30, 1997 were $809,437 resulting in a
gross margin of $157,971 or 16%. This compares to a gross margin of 15% for the
prior year. Fiscal 1997 margins reflect the impact of reduced manufacturing
costs for the entire year from off-shore assembly. Gross margin percentage is
highly dependent on sales prices, production volumes, costs and manufacturing
overhead allocations. Past margins are not necessarily indicative of future
margins given the uncertainty and timing of both existing product sales and new
product offerings.

Research and development costs for the year ended September 30, 1997 were
$566,288 compared to $160,934 for the prior year. The $405,354 increase resulted
primarily from an increase in HSS technology development activities and related
costs. In the current fiscal year personnel costs increased by approximately
$175,000, equipment and component costs by $55,000 and outside design and
consulting increased by approximately $167,000 as compared to the prior year.

Research and development costs vary quarter by quarter due to the timing of
projects, the availability of funds for research and development and the timing
and extent of use of outside consulting, design and development firms. The
Company expects fiscal 1998 research and development costs to be at higher
levels due to increased staffing and expanded use of outside design and
consultants primarily associated with HSS technology development. The Company is
seeking additional engineering and support personnel to further expand research
and development on HSS and other technologies in future periods.

Selling, general and administrative expenses increased from $555,950 for the
year ended September 30, 1996 to $1,616,568 for the year ended September 30,
1997. The $1,060,618 increase included a $273,000 non-employee non-cash
compensation expense related to the granting of stock options and warrants
during fiscal 1997, a $41,000 increase in commissions primarily associated with
large accounts, a $303,000 increase in personnel costs primarily associated with
HSS technology marketing, a $93,000 increase in marketing travel and related
costs, a $135,000 increase in costs associated with marketing and promoting the
HSS technology, a $25,000 increase in office related costs primarily associated
with the new lease of larger space and more personnel, and an $140,000 increase
in professional and financing fees associated with preparing HSS technology
licensing information and new financings. Management anticipates that selling,
general and administrative costs will continue at higher levels in fiscal 1998
due to the recent executive additions and expanded HSS technology marketing
personnel, travel and related operations and costs.

As a result of the above factors, the Company experienced a loss from operations
of $2,024,885 during the year ended September 30, 1997, compared to a loss from
operations of $580,395 for the comparable year ended September 30, 1996. The
increase in the operating losses resulted primarily from increases in research
and development costs and selling, general and administrative costs associated
with the HSS technology. The Company expects to incur continued operating losses
until it is able to commercialize its HSS or other technologies and produce
revenues sufficient to support operating costs. There can be no assurance the
Company will be successful in such efforts.

                                       15

During the year ended September 30, 1996, the Company recognized a gain of
$55,019 from the sale of NCI shares. No sales were made in fiscal 1997. During
the second fiscal 1997 quarter, the Company incurred $125,200 of non-cash
interest expense consisting of $2,500 of value assigned to stock purchase
warrants and $122,700 as embedded interest on convertible notes based on the
difference between the conversion price and the market price at the issue date.
A like amount was recorded as paid in capital. Through September 30, 1997 an
additional $18,461 of non-cash interest was paid or payable in common shares
related to the convertible notes.

The Company reported a net loss of $2,144,363 for the year ended September 30,
1997, compared to a net loss of $560,448 for the year ended September 30, 1996.
The Company has federal net loss carryforwards of approximately $3,600,000 for
federal tax purposes expiring through 2012. The amount and timing of the
utilization of the Company's net loss carryforwards may be limited under Section
382 of the Internal Revenue Code. A valuation allowance has been recorded to
offset the related net deferred tax asset as management was unable to determine
that it is more likely than not that the deferred tax asset will be realized.
See Note 6 to the accomanying financial statements.

The net loss available to common stockholders for the fiscal year ended
September 30, 1997 was increased in computing loss per share of common stock by
an imputed deemed dividend in the amount of $617,646 or $.07 per share. The
imputed deemed dividend resulted from a discount provision included in the
Series A Convertible Preferred Stock issued in August 1997. This imputed deemed
dividend is not a contractual obligation on the part of the Company to pay such
imputed dividend.

Future operations are subject to significant variability as a result of product
sales and margins, timing of new product offerings, the success and timing of
new technology exploitation, decisions regarding future research and development
and variability in other expenditures.

LIQUIDITY AND CAPITAL RESOURCES
Since the Company recommenced operations in January 1992, the Company has had
significant negative cash flow from operating activities. The negative cash flow
from operating activities was $1,572,425 for the fiscal year ended September 30,
1997 and $611,350 for the fiscal year ended September 30, 1996. During fiscal
1997, the net loss of $2,144,363 included non-cash expenses of $723,595
resulting in an adjusted net cash loss of $1,420,768. In addition to this amount
of $1,420,768, cash was used in operating activities through an increase in
customer accounts receivable of $111,717 and a $227,319 decrease in accounts
payable. Operating cash was provided by a $31,630 reduction in prepaid expenses,
a $124,116 reduction in inventories and a $31,633 increase in accrued
liabilities.

At September 30, 1997 the Company had approximately 115 days sales in accounts
receivable as compared to 75 days at September 30, 1996. The unusually high
level of receivables at September 30, 1997 was due to sales to Target and CR
McMullen on terms demanded by the large retail chains that often require 90-120
day terms on sales. However, receivables can vary dramatically due to quarterly
and seasonal variations in sales and timing of shipments to and receipts from
large customers.

For the year ended September 30, 1997, the Company used approximately $177,000
for the purchase of laboratory equipment and made a $101,000 investment in
patents. The Company estimates a significant level of investments in patents in
fiscal 1998 and requirements for additional equipment for developing HSS and
other technologies. Dollar amounts of these patent investments and equipment
additions are not currently estimable by management.

At September 30, 1997, the Company had working capital of $3,719,807 and at
September 30, 1996 had working capital of $1,047,787. Included in working
capital is the unrealized holding gain in the shares held by the Company in
NASDAQ quoted NCI. At September 30, 1997 and 1996, the Company owned 225,300
shares of NCI with a market value of $29,289 and $190,153, respectively. This
investment is carried on the balance sheet as a current asset of the Company at
market value pursuant to Statement of Financial Accounting Standards No. 115
(SFAS No. 115), "Accounting for Certain Investments in Debt and Equity
Securities" which was adopted by the Company effective September 30, 1994.
Although the shares of NCI have experienced significant price and volume
variability, these shares have provided a source of liquidity for the Company.

Since the Company's reorganization in January 1992 and through June 30, 1997,
the Company has financed its operations primarily through the sale of common
equity, exercise of stock options, issuances of convertible notes and proceeds
from the sale of shares of NCI. Included in the exercise of stock options in
fiscal 1997 was a net of $153,250 financed by officer loans. These sources plus
the recent sale of $3.3 million (net proceeds) of convertible preferred stock
provided $4,531,553 of net cash from financing activities during fiscal 1997,
significantly improving the Company's financial position.



                                       16
<PAGE>   17

Other than cash of $3.3 million at September 30, 1997 and the NCI shares, the
Company has no other material unused sources of liquidity at this time. The
Company expects to incur additional operating losses as a result of continued
product sale operations and as a result of expenditures for research and
development and marketing costs for HSS technology and other products and
technologies. The timing and amounts of the Company's expenditures and the
extent of operating losses will depend on many factors, some of which are beyond
the Company's control. The Company anticipates that the commercialization of HSS
technology will require increased personnel and operating costs. The Company
believes it has sufficient financial resources for the next twelve months of
operations. However this estimate is subject to significant variability and
change due to management decisions regarding technologies, operations and the
result of outside factors. The long-term success of the Company is dependent
upon achieving a level of revenues adequate to support the Company's capital and
operating requirements.

NEW ACCOUNTING PRONOUNCEMENTS
The Financial Accounting Standards Board has issued a number of new
pronouncements for future implementation as discussed in the footnotes to the
Company's financial statements (see page F-8). As discussed in the notes to the
financial statements, the implementation of these new pronouncements is not
expected to have a material effect on the financial statements.

BUSINESS RISKS
This report contains a number of forward-looking statements which reflect the
Company's current views with respect to future events and financial performance.
These forward-looking statements are subject to certain risks and uncertainties,
including those discussed below, that could cause actual results to differ
materially from historical results or those anticipated. In this report, the
words "anticipates," "believes," "expects," "intends," "future" and similar
expressions identify forward-looking statements. Readers are cautioned to
consider the specific risk factors described below and not to place undue
reliance on the forward-looking statements contained herein, which speak only as
of the date hereof. The company undertakes no obligation to publicly revise
these forward-looking statements, to reflect events or circumstances that may
arise after the date hereof.

History of Losses; Absence of Profitability; Variability of Results; and
Reliance on Customers - The Company has an accumulated deficit of $4,170,300
with net losses of $2,144,363 for fiscal 1997 and $560,448 for fiscal 1996. The
Company expects to incur additional operating losses in future quarters until
and if it is able to generate operating revenues and margins sufficient to
support expenditures. There is no assurance that the Company will be able to
achieve or sustain significant periods of profitability in the future. The sales
of the Company's products are subject to significant quarterly and seasonal
variability. The Company has been and is expected to continue to be reliant on a
limited number of customers, the loss of which would have an adverse effect on
the Company's financial condition and results of operations.

HSS Technology in Development; No Assurance of Completion; May Be Subject to
Additional Delays -The HSS technology is in development and has not been
developed to the point of commercialization. There can be no assurance that a
commercially viable system can be completed due to the inherent risks of new
technology development, limitations on financing, competition, obsolescence,
loss of key technical personnel and other factors. The Company has not generated
any revenues from the HSS technology to date, and has no agreements or
arrangements providing any assurance of revenues in the future. The development
of HSS technology has taken longer than anticipated by management and could be
subject to additional delays. There can be no assurance of timely completion of
commercially viable HSS technology or that if available that it will perform on
a cost-effective basis, or that if introduced, that it will achieve market
acceptance. The Company's various development projects are high risk in nature,
where unanticipated technical obstacles can arise at any time and result in
lengthy and costly delays or result in determination that further development is
unfeasible.

Future Dependent on Market Acceptance of the HSS Technology - The future of the
Company is largely dependent upon the success of the HSS technology or the
development of new technologies. There can be no assurance the Company can
introduce any of its technologies or that if introduced they will achieve market
acceptance sufficient to sustain the Company or achieve profitable operations.

Significant Competition and Possible Obsolescence - Technological competition
from other and longer established electronic and loudspeaker manufacturers is
significant and expected to increase. Most of the companies with which the
Company expects to compete have substantially greater capital resources,
research and development staffs, marketing and distribution programs and
facilities, and many of them have substantially greater experience in the
production and marketing of products. In addition, one or more of the Company's
competitors may succeed in developing technologies and products that are more
effective than any of those being developed by the Company, rendering the
Company's technology and products obsolete or noncompetitive.

                                       17
<PAGE>   18

New Technology Faces Many Barriers and Risks - The introduction of new
technology, such as HSS, targeted for wide use often faces barriers to
commercialization and many risks that cannot currently be identified. The HSS
technology employs ultrasonics. Although ultrasonics are employed in a wide
variety of medical and industrial applications, there can be no assurance that
the Company will not face barriers to introduction due to the use of
ultrasonics. The Company's technology uses relatively small amounts of
ultrasonic energy which dissipates rapidly in air. The Company employs
frequencies above those that may be harmful to pets but within those used by
medical devices directly coupled to the body to image fetuses and the brain.
Although the Company believes the frequencies and the amount of energy employed
is harmless, and that the emission of such frequencies is not presently subject
to government regulation, there can be no assurance that barriers to
commercialization will not develop or that the use of such ultrasonics will not
be subject to future regulation or interpretation of existing regulation.

Dependence On Third Party Strategic Alliances and Business Relationships - The
Company's strategy is to establish business relationships with leading
participants in various segments of the electronics and sound reproduction
markets. The Company believes this strategy will enable it to take advantage of
the superior financial resources, technological capabilities, proprietary
positions and market presence of these companies in establishing and maintaining
HSS technology in sound reproduction. Although the Company's strategy is to
establish closer relationships with selected companies through specific product
collaborations, there can be no assurance that HSS technology can be developed
to commercialization for such uses or that the Company can successfully
collaborate to develop commercial products to exploit the HSS technology.

The Company's success will depend on its ability to enter into additional
strategic arrangements with new partners on commercially reasonable terms. Any
future relationships may require the Company to share control over its
development, manufacturing and marketing programs or to relinquish rights to
certain versions of its technology.

Patents and Proprietary Rights Subject to Uncertainty - The Company possesses
two U.S. patents on ear radios which the Company relies on to protect its market
position in the U.S. The Company has eleven patents pending on its HSS
technology and the Company is considering additional patent applications. There
can be no assurance that any patents held by the Company will not be challenged
and invalidated, that patents will issue from any of the Company's pending
applications or that any claims allowed from existing or pending patents will be
of sufficient scope or strength. There can be no assurance the patents will be
issued in all countries where the Company's products can be sold or licensed to
provide meaningful protection or any commercial advantage to the Company.
Competitors of the Company may also be able to design around the Company's
patents. The electronics industry is characterized by vigorous protection and
pursuit of intellectual property rights or positions, which have resulted in
significant and often protracted and expensive litigation. There is currently no
pending intellectual property litigation against the Company. There is no
assurance, however, that the Company's technologies or products do not and will
not infringe the patents or proprietary rights of third parties. Problems with
patents or other rights could potentially increase the cost of the Company's
products, or delay or preclude new product development and commercialization by
the Company. If infringement claims against the Company are deemed valid, the
Company may seek licenses which might not be available on acceptable terms or at
all. Litigation could be costly and time-consuming but may be necessary to
protect the Company's future patent and/or technology license positions, or to
defend against infringement claims. A successful challenge to the HSS technology
could have a materially adverse effect on the Company and its business
prospects. There can be no assurance that any application of the Company's
technologies will not infringe upon the proprietary rights of others or that
licenses required by the Company from others will be available on commercially
reasonable terms, if at all.

Ear Radio Assembly Dependent on Subcontractors; Possible Disruptions in
Components - With respect to the assembly of the Company's FM ear radio, which
accounts for substantially all of the Company's revenues, the Company is
dependent on subcontract assemblers. The Company believes that there are a
number of electronic product subcontract assembly companies located in North
America and overseas that are qualified to produce the Company's ear radio.
However, any disruption of supply could cause additional costs and delays and
could have a material adverse impact on the Company's results of operations. The
assembly of ear radios is dependent upon the availability of electronic
components. The Company believes there are secondary suppliers of components and
subassemblies such that it is not reliant on one supplier, although delays could
result should the Company be required to change suppliers of longer lead time
components or subassemblies. Any significant delays in obtaining components from
existing or secondary suppliers through supplier changes or from component
shortages, which are common to the electronics industry, could have a material
adverse impact on the Company's results of operations.

Performance Dependent on Key Personnel; Limited Key Person Life Insurance;
Success Dependent on Additional Personnel - The Company's performance is
substantially dependent on the performance of its executive officers and key
technical employees. Given the Company's early stage of development, the Company
is dependent on its ability to retain and motivate high quality personnel,
especially its management and highly skilled technical personnel. Other than a
$2 million policy on Elwood G. Norris, inventor of the Company's technologies,
the Company does not maintain any

could have a material adverse effect on the business, operating results or
financial condition of the Company. The Company's future success and growth also
depends on its continuing ability to identify, hire, train and retain other
highly qualified technical and managerial personnel. Competition for such
personnel is intense, and there can be no assurance that the Company will be
able to attract, assimilate or retain other highly qualified technical and
managerial personnel in the future. The inability to attract and retain the
necessary technical and managerial personnel could have a material adverse
effect upon the Company's business, operating results or financial condition.

General Conflicts of Interest Due to Part-Time Management and Relationships - As
more fully disclosed in "Item 9" below, certain of the Company's officers,
including Mr. Norris, the inventor of the Company's technologies, devote only
part-time services to the Company and have other employment and business
interests to which they devote attention and will continue to do so, resulting
in certain conflicts of interest.

No Active Trading Market; Market Volatility - The Company's shares are traded on
the OTC Bulletin Board, a screen-based trading system operated by the National
Association of Securities Dealers, Inc. Securities traded on the OTC Bulletin
Board are, for the most part, thinly traded and are subject to special
regulations not imposed on securities listed or traded on the NASDAQ system or
on a national securities exchange. The Company's shares, like that of the
securities of other small, growth-oriented companies, have experienced in the
past and are expected to experience in the future significant price and volume
volatility thereby increasing the risk of ownership to investors. Historically,
the Company's Common Stock has experienced low trading volume. There can be no
assurance that the market price of the Common Stock will remain at its present
level, and any future changes in market price cannot be predicted as to timing
or extent. Past performance of the Common Stock does not guarantee and should
not be construed to imply future performance. Factors such as announcements by
the Company or its competitors concerning technological innovations, new
commercial products or procedures, proposed government regulations and
developments or disputes relating to patents or proprietary rights may have a
significant effect on the market price of the Common Stock. Changes in the
market price of the Common Stock may have no connection with the Company's
actual financial results.

CONFLICTS OF INTEREST
Certain conflicts of interest now exist and will continue to exist between the
Company and certain of its officers and directors due to the fact that they have
other employment or business interests to which they devote some attention and
they are expected to continue to do so. The Company has not established policies
or procedures for the resolution of current or potential conflicts of interest
between the Company and its management or management-affiliated entities. There
can be no assurance that members of management will resolve all conflicts of
interest in the Company's favor. The officers and directors are accountable to
the Company as fiduciaries, which means that they are legally obligated to
exercise good faith and integrity in handling the Company's affairs. Failure by
them to conduct the Company's business in its best interests may result in
liability to them.

It is conceivable that the respective areas of interest of the Company, Patriot
and NCI could overlap or conflict. The Company believes that although each of
the three corporations are involved in the electronics industry, the respective
areas of focus, products and technology directions of the three companies are
sufficiently distinct such that no conflict in business lines or executive
loyalties will result. Because of this unlikelihood, no steps have been taken to
resolve possible conflicts, and any such conflicts, should they arise, will be
addressed at the appropriate time.

Mr. Norris and Mr. Putnam are officers and directors of multiple public
companies as outlined above and Mr. Putnam is subordinate to Mr. Norris in these
relationships. The Company has not provided a method of resolving any potential
conflicts arising from these relationships and probably will not do so, partly
due to inevitable extra expense and delay any such measures would occasion. Mr.
Norris and Mr. Putnam are obligated to perform their duties in good faith and to
act in the best interest of the Company and its shareholders, and any failure on
their part to do so may constitute a breach of their fiduciary duties and expose
them to damages and other liability under applicable law. While the directors
and officers are excluded from liability for certain actions, their is no
assurance that Mr. Norris or Mr. Putnam would be excluded from liability or
indemnified if they breached their loyalty to the Company.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
Section 16(a) of the Securities Exchange Act of 1934 (the "Act") requires the
Company's officers, directors and persons who own more than 10% of a class of
the Company's securities registered under Section 12(g) of the Act to file
reports of ownership and changes in ownership with the Securities and Exchange
Commission ("SEC"). Officers, directors and greater than 10% shareholders are
required by SEC regulation to furnish the Company with copies of all Section
16(a) forms they file.

Based solely on a review of copies of such reports furnished to the Company and
written representations that no other reports were required during the fiscal
year ended September 30, 1997, the Company believes that all persons subject to
the reporting requirements pursuant to Section 16(a) filed the required reports
on a timely basis with the SEC.

ITEM 10. EXECUTIVE COMPENSATION.

There is shown below information concerning the compensation of the two
individuals who acted as the Company's chief executive officer (each a "Named
Executive Officer") for the fiscal year ended September 30, 1997. Compensation
for the other four most highly compensated executive officers of the Company is
not required nor presented as no such other executive officer's salary and bonus
exceeded $100,000 during the fiscal year ended September 30, 1997.

During the fiscal year ended September 30, 1997, the Company did not adjust or
amend the exercise price of stock options awarded to the Named Officers and the
Company has no defined benefit or actuarial plans covering any person.

COMPENSATION OF DIRECTORS
No direct or indirect remuneration has been paid or is payable by the Company to
the directors in their capacity as directors. It is anticipated that during the
next twelve months that the Company will not pay any direct or indirect
remuneration to any directors of the Company in their capacity as directors
other than in the form of reimbursement of expenses of attending directors' or
committee meetings. However, directors have received in the past, and may
receive in the future, stock options.

EMPLOYMENT CONTRACTS
Mr. Putnam had no employment contract while he was President and CEO of the
Company. Effective September 1, 1997 the Company entered into three year
employment contract with Mr. Williams, Chairman, President and CEO. The
agreement provides for a base salary of $20,000 per month, subject to future
reviews. The agreement provides for a minimum performance bonus of 50% of base
compensation in the first year, payable early if a significant license agreement
is attained. Future bonuses are at the discretion of the Board of Directors. The
Company may terminate the employment with or without cause (as defined), but
termination without cause (other than disability or death) results in a
severance payment equal to twelve months of the then monthly base salary and any
bonus on an as if perfected basis payable in one lump sum. Likewise upon a
change in control, as defined in the agreement, Mr. Williams may elect to
terminate employment and obtain a payment equal to the remaining months of the
agreement multiplied by the base salary and any bonus on an as if perfected
basis payable in one lump sum. Mr. Williams has agreed not to disclose trade
secrets during employment and for three years thereafter and has agreed to
assign inventions to the Company (as defined) during employment to the Company.
In connection with the employment agreement, the Company granted Mr. Williams
options to purchase up to 862,000 common shares at $5.81 per share, with 250,000
shares vesting on the date of the grant and the balance over three years with
certain amounts subject to acceleration for certain events.

ITEM 12. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

The Company is obligated to pay to Elwood G. Norris, a director, a 1% royalty on
all sales of radio equipment based on the gross amount received by the Company
less returns and allowances pursuant to a September 3, 1985 royalty agreement.
Pursuant to an Addendum Agreement dated December 2, 1996, the Company is also
obligated to pay Mr. Norris a 2% royalty on gross revenues received by the
Company from the GPS and HSS technologies.

Elwood Norris, a director of the Company, is also Chairman, CEO and Chief
Technology Officer of NCI. He is the beneficial owner of 709,838 shares of NCI
(representing approximately 1% of its issued and outstanding shares at October
31, 1997) and Robert Putnam (the Vice President, Treasurer and Asst. Secretary
of the Company) is Secretary of NCI and the beneficial owner of 40,000 shares of
NCI (representing less than 1% of its issued and outstanding shares).



                                       23

Pursuant to an agreement dated March 23, 1988 between the Company and NCI, the
Company sold NCI all of the issued and outstanding shares in its wholly-owned
subsidiary Norcom Communications Corporation (now JABRA) in consideration of the
Company's receipt of 700,000 common shares of NCI, subject to escrow and
earn-out provisions which were subsequently fulfilled. At the time of the sale
of JABRA to NCI, JABRA had a book value of $400. The Company still owns 225,300
of these common shares of NCI as of the date of this annual report.

In 1993 NCI entered into agreements selling a portion of its ownership in JABRA
to an investment group which has resulted in Norris no longer owning a majority
interest in JABRA nor controlling its affairs. Although the Company was a
signatory to certain sections of these agreements relating to the EarPHONE
technology and royalties, the Company was not a beneficiary or material party to
these transactions by NCI.

The Company and Mr. Norris are each entitled to 1% royalties on certain gross
invoice amounts received by JABRA on devices using the EarPHONE technology. The
Company received its royalty right under agreements dated January 25, 1988 and
March 22, 1988 by which the Company transferred all right, title and interest in
and to the EarPHONE to JABRA. By letter agreement dated January 14, 1993 it was
clarified that the Company's 1% royalty would be due only on gross sales of
JABRA products incorporating a wireless receiver sold until the expiration of
the last patent relating to the EarPHONE technology. JABRA has not introduced a
wireless product and therefore there can be no assurance of future royalties. On
October 31, 1997, the Company agreed to sell and cancel its 1% royalty interest
to JABRA for $15,000, subject to receipt of funds by November 15, 1997.

On June 4, 1996, the Company paid $50,788 to Elwood G. Norris reducing the
principal balance of a 1991 note due and payable on October 1, 1996 to $100,000.
In connection with the placement of $220,000 of convertible notes to other
unrelated investors, the balance of the note to Mr. Norris was converted into a
new note on terms comparable to the unrelated investors. Accordingly the Company
executed a new unsecured 8% Convertible Subordinated Promissory Note due May 31,
1999 payable to Mr. Norris for $100,000. Pursuant to the conversion terms of the
note, Mr. Norris converted the principal amount of the note into 100,000 shares
of the Company's common stock at the conversion price of $1.00 per share on
September 27, 1996. On the same terms as the other investors, Mr. Norris was
also granted warrants to purchase up to 100,000 of the Company's common shares
until May 31, 1998 at an exercise price of $1.00 per share.

During the fiscal year ended September 30, 1997, the Company paid $15,000 to NCI
for rent of its operating facility The Company also paid NCI for contract
manufacturing services on ear radio production totaling $48,000 during fiscal
1997. The Company believes these services were performed on terms comparable to
those from independent parties.

On July 11, 1997, the Company entered into a three year lease. To meet the
credit requirements of the landlord, both the Company and NCI entered into a
joint lease agreement for approximately 12,925 square feet with aggregate
monthly payments of $13,830 inclusive of utilities and costs. The Company is
occupying approximately 7,500 square feet of the jointly leased office space
with its share of monthly payments being approximately $8,000. Accordingly the
Company could become obligated for the entire lease should NCI default on its
share of payments thereon.

In January 1997 the Company made unsecured cash demand loans with interest at 7%
per annum to two officers aggregating $173,250 (Mr. Putnam as to $82,500 and Mr.
Norris as to $90,750). The proceeds of the loans were used by the officers to
exercise Company stock options. Each officer made a $10,000 principal payment
plus interest during the year. Although the notes are payable on demand, the
Board of Directors has advised the officers that they shall have until September
30, 1998 to repay the notes.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS


To the Stockholders and Board of Directors
American Technology Corporation
San Diego, California

We have audited the accompanying balance sheet of American Technology
Corporation as of September 30, 1997 and the related statements of operations,
stockholders' equity and cash flows for each of the two years in the period then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of American Technology Corporation
as of September 30, 1997, and the results of its operations and its cash flows
for each of the two years in the period then ended in conformity with generally
accepted accounting principles.

                                                  SUMMARY OF ACCOUNTING POLICIES

ORGANIZATION            American Technology Corporation (the "Company"), a   
AND                     Delaware corporation, is engaged in the development, 
BUSINESS                manufacture and marketing of consumer electronic     
                        products and acoustic technologies.                  

USE OF                  The preparation of financial statements in conformity   
ESTIMATES               with generally accepted accounting principles requires  
                        management to make estimates and assumptions that affect
                        the reported amounts of assets and liabilities and      
                        disclosure of contingent assets and liabilities at the  
                        date of the financial statements and the reported       
                        amounts of revenues and expenses during the reporting   
                        period. Actual results could differ from those          
                        estimates.                                              
                        
FINANCIAL INSTRUMENTS   The Company's financial instruments that are exposed to
AND CONCENTRATIONS OF   concentrations of credit risk consist primarily of cash
CREDIT RISK             and trade  accounts receivable.

                        The Company's cash is placed in quality money market
                        accounts with major financial institutions. The
                        investment policy limits the Company's exposure to
                        concentrations of credit risk. Such deposit accounts at
                        times may exceed federally insured limits. The Company
                        has not experienced any losses in such accounts.

                        Concentrations of credit risk with respect to the trade
                        accounts receivable are limited due to the wide variety
                        of customers and markets which comprise the Company's
                        customer base, as well as their dispersion across many
                        different geographic areas. The Company routinely
                        assesses the financial strength of its customers and, as
                        a consequence, believes that the trade accounts
                        receivable credit risk exposure is limited. Generally,
                        the Company does not require collateral or other
                        security to support customer receivables.

                        The carrying amounts of financial instruments including
                        cash, trade accounts receivable, notes
                        receivable-officers, accounts payable and accrued
                        liabilities approximated fair market value because of
                        the immediate or short-term maturity of these
                        instruments. The difference between the carrying amount
                        of the Company's convertible notes and their fair market
                        value is not considered significant.

INVESTMENT              Investment securities classified as available for sale  
SECURITIES              are those securities that the Company does not have the 
                        positive intent to hold to maturity or does not intend  
                        to trade actively. These securities are reported at fair
                        value with unrealized gains and losses reported as a net
                        amount (net of applicable income taxes) as a separate   
                        component of stockholders' equity.                      
                        
INVENTORIES             Inventories are valued at the lower of cost or market.
                        Cost is determined using the first-in, first-out (FIFO)
                        method.

EQUIPMENT AND           Equipment is stated at cost. Depreciation is computed   
DEPRECIATION            over the estimated useful lives of three years using the
                        straight line method.                                   
                        
PATENTS                 Patents are carried at cost and, when granted, will be
                        amortized over their estimated useful lives. The
                        carrying value of patents is periodically reviewed and
                        impairments, if any, are recognized when the expected
                        future benefit to be derived from individual intangible
                        assets is less than its carrying value.

REVENUE                 Sales are recorded in the periods that products are
RECOGNITION             shipped. 

                                                                             F-7

                                                  SUMMARY OF ACCOUNTING POLICIES

RESEARCH AND            Research and development costs are expensed as incurred.
DEVELOPMENT COSTS

INCOME TAXES            The Company accounts for income taxes under
                        Statement of Financial Accounting Standards ("SFAS") No.
                        109. Temporary differences are differences between the
                        tax basis of assets and liabilities and their reported
                        amounts in the financial statements that will result in
                        taxable or deductible amounts in future years.

NET LOSS                Net loss per common share is based on the weighted      
PER SHARE               average number of shares outstanding during each period 
                        presented. Options and warrants to purchase stock and   
                        debt convertible into common shares are included as     
                        common stock equivalents, when dilutive.                
                        
                        Net loss available to common stockholders was reduced in
                        computing net loss per share by an imputed deemed
                        dividend from a discount provision included in the
                        Series A Preferred Stock (see Note 7). The deemed
                        dividend is amortized to the earliest period at which
                        the preferred stock became convertible. Since the Series
                        A Stock was convertible at issuance, the entire imputed
                        conversion discount of $617,646 is recognized as a
                        deemed dividend for the fiscal year ended September 30,
                        1997. This imputed dividend is not a contractual
                        obligation on the part of the Company to pay such
                        imputed dividend. Loss per share available to common
                        stockholders is calculated as follows:

STOCK OPTIONS           The Company applies APB Opinion 25, "Accounting for
                        Stock Issued to Employees," and related Interpretations
                        in accounting for all stock option plans. Under APB
                        Opinion 25, compensation cost is recognized for stock
                        options granted to employees when the option price is
                        less than the market price of the underlying common
                        stock on the date of grant.

                        SFAS Statement No. 123, "Accounting for Stock-Based
                        Compensation," requires the Company to provide pro forma
                        information regarding net income as if compensation cost
                        for the Company's stock option plans had been determined
                        in accordance with the fair value based method
                        prescribed in SFAS No. 123. To provide the required pro
                        forma information, the Company estimates the fair value
                        of each stock option at the grant date by using the
                        Black-Scholes option-pricing model.

CASH FLOWS              considers all highly liquid investments purchased with

                                                  SUMMARY OF ACCOUNTING POLICIES

RECENT ACCOUNTING       The Financial Accounting Standards Board has issued     
PRONOUNCEMENTS          Statement of Financial Accounting Standards ("SFAS") No.
                        128, "Earnings Per Share" and Statement of Financial    
                        Accounting Standards No. 129 "Disclosures of Information
                        About an Entity's Capital Structure." SFAS No. 128      
                        provides a different method of calculating earnings per 
                        share than is currently used in accordance with         
                        Accounting Principles Board Opinion No. 15, "Earnings   
                        Per Share." SFAS No. 128 provides for the calculation of
                        "Basic" and "Dilutive" earnings per share. Basic        
                        earnings per share includes no dilution and is computed 
                        by dividing income available to common shareholders by  
                        the weighted average number of common shares outstanding
                        for the period. Diluted earnings per share reflects the 
                        potential dilution of securities that could share in the
                        earnings of an entity, similar to fully diluted earnings
                        per share. SFAS No. 129 establishes standards for       
                        disclosing information about an entity's capital        
                        structure. SFAS No. 128 and SFAS No. 129 are effective  
                        for financial statements issued for periods ending after
                        December 15, 1997. Their implementation is not expected 
                        to have a material effect on the financial statements.  
                        
                        The Financial Accounting Standards Board has also issued
                        SFAS No. 130 "Reporting Comprehensive Income" and SFAS
                        No. 131 "Disclosures About Segments of an Enterprise and
                        Related Information." SFAS No. 130 establishes standards
                        for reporting and display of comprehensive income, its
                        components and accumulated balances. Comprehensive
                        income is defined to include all changes in equity
                        except those resulting from investments by owners and
                        distributions to owners. Among other disclosures, SFAS
                        No. 130 requires that all items that are required to be
                        recognized under current accounting standards as
                        components of comprehensive income be reported in a
                        financial statement that displays with the same
                        prominence as other financial statements. SFAS No. 131
                        supersedes SFAS No. 14 "Financial Reporting for Segments
                        of a Business Enterprise." SFAS No. 131 establishes
                        standards on the way that public companies report
                        financial information about operating segments in annual
                        financial statements and requires reporting of selected
                        information about operating segments in interim
                        financial statements issued to the public. It also
                        establishes standards for disclosure regarding products
                        and services, geographic areas and major customers. SFAS
                        No. 131 defines operating segments as components of a
                        company about which separate financial information is
                        available that is evaluated regularly by the chief
                        operating decision maker in deciding how to allocate
                        resources and in assessing performance.

                        SFAS No. 130 and No. 131 are effective for financial
                        statements for periods beginning after December 15, 1997
                        and require comparative information for earlier years to
                        be restated. Because of the recent issuance of these
                        standards, management has been unable to fully evaluate
                        the impact, if any, the standards may have on the future
                        financial statement disclosures. Results of operations
                        and financial position, however, will be unaffected by
                        implementation of these standards.

4. RELATED PARTY        Facility Lease
   TRANSACTIONS         Through July 1997, the Company's research, assembly and
                        shipping and office facilities were subleased under a
                        $2,000 monthly sub-lease agreement with an affiliated
                        corporation Norris Communications, Inc. ("NCI"). On July
                        11, 1997, the Company entered into a three year lease.
                        To meet the credit requirements of the landlord, both
                        the Company and NCI entered into a joint lease agreement
                        for approximately 12,925 square feet with aggregate
                        monthly payments of $13,830 inclusive of utilities and
                        costs. The Company is occupying approximately 7,500
                        square feet of the jointly leased office space with its
                        share of monthly payments being approximately $8,000.
                        Accordingly the Company could become obligated for the
                        entire lease should NCI default on its share of payments
                        thereon.

                        Total rent expense under operating lease agreements was
                        approximately $32,000 and $39,000 for the years ended
                        September 30, 1997 and 1996.

                        Outside Manufacturing Services
                        NCI has provided certain outside manufacturing services
                        to the Company. For the years ended September 30, 1997
                        and 1996 total services provided amounted to
                        approximately $48,000 and $49,000. At September 30, 1997
                        approximately $1,600 is due to NCI for such services and
                        is included in accounts payable in the accompanying
                        balance sheet.

                                                                            F-10

                        Royalties

                        In connection with a 1992 agreement to purchase
                        technology, the Company is required to pay a
                        stockholder/director of the Company a 1% royalty on all
                        net sales of radio equipment (as defined). For the years
                        ended September 30, 1997 and 1996, total royalties paid
                        by the Company on radio sales were approximately $7,900
                        and $9,000.

                        The Company is also obligated to pay the
                        stockholder/director royalties of 2% on gross revenues
                        of the Company's sound reproduction and global
                        positioning satellite technologies. As of September 30,
                        1997 no amounts have been paid nor are due under this
                        agreement.

                        and accrued interest at 7% per annum on these demand
                        notes. Each officer made a $10,000 principal plus
                        interest payment during the year. Such notes are
                        presented as a reduction from stockholders' equity in
                        the accompanying financial statements.

5. CONVERTIBLE NOTES    During fiscal 1997, the Company raised $1,000,000
                        through the issuance of 6% convertible subordinated
                        promissory notes (the "Convertible Notes"). The
                        Convertible Notes are unsecured and are due on March 1,
                        1999. Interest on the Convertible Notes is payable in
                        cash upon maturity or in common stock upon conversion.
                        Principal and interest due under the Convertible Notes
                        may be converted, at the option of the holder, into
                        shares of the Company's common stock at a price which is
                        the lower of (i) $3.50 per share or (ii) 85% of the ten
                        day average closing bid price prior to conversion but
                        not less than $2.50 per share or (iii) for conversions
                        on or after March 1, 1998, the average closing bid price
                        for the prior thirty days but in no event less than
                        $1.00 per share. The Convertible Notes may be called by
                        the Company for conversion if the market price exceeds
                        $9.00 per share for ten days and other conditions have
                        been met. As the market price of the Company's common
                        stock exceeded the conversion price of the Convertible
                        Notes at the date of issuance, the Company recognized
                        embedded interest expense of $122,700 upon issuance of
                        the Convertible Notes.

                        The Convertible Notes were issued with detachable
                        warrants which grant the holders the right to acquire up
                        to 50,000 shares of the Company's common stock at a per
                        share price of $5.00. The warrants expire on March 1,
                        2000. The warrants were determined to have a value of
                        $2,500, which amount was recorded as additional paid-in
                        capital.

                        During 1997, holders of $625,000 of the Convertible
                        Notes converted their notes, and accrued interest
                        thereon, into 181,230 shares of the Company's common
                        stock. At September 30, 1997, the remaining $375,000 of
                        Convertible Notes, and accrued interest thereon of
                        $11,651 would have been convertible into approximately
                        110,500 shares of the Company's common stock.

                        Subsequent to September 30, 1997, an additional $25,872
                        of Convertible Notes, and accrued interest thereon, was
                        converted into 7,392 shares of common stock reducing the
                        principal amount to $350,000.


                                                                            F-11

                        A valuation allowance has been recorded to offset the

7. STOCKHOLDERS'        Fiscal 1996 Private Offerings
   EQUITY               During fiscal 1996 the Company completed a private
                        offering of 250,000 units, consisting of one share of
                        the Company's common stock and one warrant to purchase
                        one share of common stock at $0.50 per share through
                        February 23, 1999. During fiscal 1997 a total of 40,000
                        of these warrants were exercised for proceeds of
                        $20,000.

                        During fiscal 1996 the Company completed two
                        subordinated convertible note offerings. Eight percent
                        convertible notes due May 31, 1999 were sold for cash of
                        $220,000 and an additional $100,000 was issued to a
                        director and stockholder to refinance the $100,000
                        balance remaining on such stockholder note with a due
                        date of October 1, 1996. An aggregate of 320,000
                        warrants expiring May 31, 1998 were granted to the note
                        holders each exercisable into one common share at an
                        exercise price of $1.00 per share. All $320,000 of the
                        8% convertible notes plus accrued interest were
                        converted to common stock prior to the end of the fiscal
                        year and 220,000 of the warrants were exercised prior to
                        September 30, 1996.

                        The second note offering consisted of 6% subordinated
                        convertible notes due July 31, 1998 sold for cash of
                        $700,000. The 6% convertible notes were convertible into
                        common stock at a price ranging from $0.80 per share to
                        $2.00 per share. Prior to September 30, 1996 all of
                        these notes and accrued interest were converted to
                        common stock at $2.00 per share.

                        Preferred Stock
                        The Company is authorized to issue 5,000,000 shares of
                        preferred stock, $.00001 par value, without any action
                        by the stockholders. The board of directors has the
                        authority to divide any and all shares of preferred
                        stock into series and to fix and determine the relative
                        rights and preferences of the preferred stock, such as
                        the designation of series and the number of shares
                        constituting such series, dividend rights, redemption
                        and sinking fund provisions, liquidation and dissolution
                        preferences, conversion or exchange rights and voting
                        rights, if any. With respect to voting rights, if the
                        preferred stock were permitted to vote in the election
                        of directors or on other matters, each such share would
                        be entitled to one vote, and such shares may vote with
                        the shares of Common Stock or may vote as a separate
                        class. Issuance of preferred stock by the board of
                        directors could result in such shares having dividend
                        and/or liquidation preferences senior to the rights of
                        the holders of Common Stock and could dilute the voting
                        rights of the holders of Common Stock.

                        The Company has designated 350,000 shares of its
                        preferred stock as Series A Convertible Preferred Stock
                        ("Series A Stock") all of which were issued at September
                        30, 1997. The Series A Stock was sold at $10.00 per
                        share in a private offering for gross proceeds of
                        $3,500,000 and net proceeds, after $178,847 of offering
                        costs, of $3,321,153.

                        The Series A Stock is non-voting except in certain
                        matters affecting the Preferred Stockholders. The
                        holders of Series A Stock shall be entitled to
                        dividends, when, as, and if declared by the Board of
                        Directors. The Preferred Stock has a liquidation
                        preference of $10.00 per preferred share plus $0.60 per
                        share per annum from issuance and certain other
                        adjustments. There is no further participation after the
                        liquidation preference is paid. There are no mandatory
                        or optional redemption rights. In a merger or
                        consolidation, the Preferred Stock shall retain the same
                        economic benefits as the Preferred Stock just prior to
                        such transaction. As long as the Company is in
                        compliance in all material respects with its obligations
                        to the Preferred Stockholders and the underlying common
                        shares are registered, all the Preferred Stock not
                        already converted shall be converted to Common Stock in
                        accordance with the conversion terms on August 25, 1998.

                                                                            F-13

                        Each share of Series A Stock is convertible (minimum
                        conversions of 10,000 Series A shares or the balance
                        held by each holder) into that number of Common Shares
                        determined by dividing $10.00, plus an amount accruing
                        at $0.60 per annum, by 85% of the average of the closing
                        bid prices of the Company's Common Stock each day for
                        the five trading days immediately preceding the date of
                        conversion provided that in no event shall such amount
                        to be multiplied by 85% be less than $3.00 per share or
                        greater than $5.75 per share. The Company may force
                        conversion of the Series A Stock if the closing bid
                        price of the Common Stock equals or exceeds $14.00 per
                        share for ten consecutive trading days and certain other
                        conditions are met.

                        The Company granted the holders of Series A Stock
                        warrants to purchase an aggregate of 175,000 Common
                        Shares at $7.50 per share until August 1, 2000.

                        At September 30, 1997 the 350,000 shares of Series A
                        Stock would have been convertible into approximately
                        777,000 common shares. Subsequent to September 30, 1997
                        a total of 110,000 shares of Series A Stock (original
                        issue value of $1,100,000) were converted into 245,189
                        shares of common stock.

                        Warrants
                        In addition to the warrants described above, during
                        fiscal 1997 the Company granted warrants to purchase

                        1997 Employee Stock Compensation Plan ("ESC") 
                        Effective March 10, 1997, the Company adopted the ESC
                        Plan, expiring March 9, 2000, reserving for issuance
                        100,000 shares of the Company's Common Stock. The ESC
                        Plan provides for compensation awards of the Company's
                        common stock to non-executive employees (as defined), at
                        the discretion of the ESC Plan committee. During fiscal
                        1997, the Company issued 40,327 shares of common stock
                        under the Plan recording non-cash compensation expense
                        of $201,414 for awards valued at an estimated fair
                        market value ranging from $3.75 to $6.38 per share.

                        1992 Incentive Stock Option Plan ("ISO") 
                        The Company has an ISO Plan, expiring March 2, 2002,
                        originally reserving for issuance 1,000,000 shares of
                        the Company's common stock. The ISO Plan provides for
                        grants to either full or part time employees, at the
                        discretion of the Board of Directors, options to
                        purchase common stock of the Company at a price not less
                        than the fair market value of the shares on the date of
                        grant. In the case of a significant stockholder, the
                        option price of shares will not be less than 110 percent
                        of the fair market value of the share on the date of
                        grant. Any options granted under the ISO Plan must be
                        exercised within ten years of the date they were granted
                        (five years in the case of a significant stockholder).
                        As of September 30, 1997, there were options outstanding
                        covering 477,000 shares of Common Stock under this plan.

                        1992 Non-Statutory Stock Option Plan ("NSO")
                        The Company has an NSO Plan, expiring March 2, 2002,
                        originally reserving for issuance 1,000,000 shares of
                        the Company's common stock. The NSO Plan provides for
                        grants to either full or part time employees, at the
                        discretion of the Board of Directors, options to
                        purchase common stock of the Company at a price not less
                        than the fair market value of the shares on the date of
                        grant. Any options granted under the NSO Plan must be
                        exercised within ten years of the date they were
                        granted. As of September 30, 1997, there were options
                        outstanding covering 333,500 shares under this plan.

                        During fiscal 1997, the Company granted 97,500 options
                        under this plan to non-employees recording non-cash
                        compensation expense of $244,800. Also during fiscal
                        1997, 292,963 common shares were issued in connection
                        with the cashless exercise of stock options under this
                        plan relating to 350,000 shares.

                        Other Stock Options
                        During fiscal 1997 the Company granted to an executive
                        officer options on up to 862,000 Common Shares vesting
                        over a period of three years, subject to acceleration.
                        These options are exercisable at $5.81 per share until
                        August 31, 2002.

                        Stock Option Pro Forma and Summary Information
                        FASB Statement No. 123, "Accounting for Stock-Based
                        Compensation" ("SFAS No. 123"), requires the Company to
                        provide pro forma information regarding net loss and net
                        loss per share as if compensation costs for the
                        Company's stock option plans and other stock awards had
                        been determined in accordance with the fair value based
                        method prescribed in SFAS No. 123. The Company estimates
                        the fair value of each stock award (those under the
                        stock option plans described above plus the 90,000
                        warrants for consulting services) at the grant date by
                        using the Black-Scholes option-pricing model with the
                        following weighted average assumptions used
                        respectively; dividend yield of zero percent for all
                        years; expected volatility of 45 percent: risk-free
                        interest rates of 5.7 to 6.5 percent; and expected lives
                        of 2 to 5 years.

                        Under the accounting provisions for SFAS No. 123, the
                        Company's net loss per common share would have been
                        increased by the pro forma amounts indicated below:

                        During the initial phase-in period of SFAS No. 123, the
                        effect on pro forma results are not likely to be
                        representative of the effects on pro forma results in

 8.CUSTOMERS,           The Company's financial instruments that are exposed to 
    FINANCIAL           concentrations of credit risk consist primarily of cash 
    INSTRUMENTS,        and trade accounts receivable.                          
    CONCENTRATIONS                                                             
    OF CREDIT RISK      The Company's cash equivalents are in demand deposit    
    AND EXPORT          accounts placed with major financial institutions. The  
    SALES               investment policy limits the Company's exposure to      
                        concentrations of credit risk. Such deposit accounts at 
                        times may exceed federally insured limits. The Company 
                        has not experienced any losses in such accounts.       
                        
                        The carrying amounts of financial instruments including
                        cash, accounts receivable, accounts payable and accrued
                        liabilities approximated fair value because of the
                        immediate or short-term maturity of these instruments.

                        During the year ended September 30, 1997, sales to three
                        individual customers accounted for 30%, 14% and 13% of
                        total net sales. During the year ended September 30,
                        1996, sales to two individual customers accounted for 
                        14% and 11% of total net sales.

                                                                            F-16

                        The Company markets its ear-radio to four major segments
                        of customers, including retail outlets, catalog
                        distribution, television and premium/specialty markets.
                        At September 30, 1997 total trade accounts receivable
                        included approximately $245,153 due from retail outlets
                        for which extended credit terms were granted.

                         Export sales were approximately 2% and 27% of sales for
                         the years ended September 30, 1997 and 1996. A summary
                         of the Company's sales by geographical areas is as

                        The Company has no foreign assets.

9. SUBCONTRACTOR        The Company is dependent on a foreign subcontractor for 
    AND SUPPLIER        the assembly of its FM ear-radio which accounted for    
    AGREEMENTS          substantially all of the Company's revenues during the  
                        year ended September 30, 1997. The Company believes that
                        there are a number of electronic product subcontract    
                        assembly companies located in North America and overseas
                        that are qualified to produce the Company's FM ear-radio
                        should the existing supplier be unable or unwilling to  
                        do so, however any disruption of supply could cause     
                        additional costs and delays and could have an adverse   
                        impact on the Company's operations. The assembly of     
                        ear-radios is dependent upon the availability of        
                        electronic components. The Company believes there are   
                        secondary suppliers of components and subassemblies such
                        that it is not reliant on one supplier, although delays 
                        could result should the Company be required to change   
                        suppliers of longer lead time components or             
                        subassemblies. Any significant delays in obtaining      
                        components from existing or secondary suppliers through 
                        supplier changes or from component shortages, which are 
                        common to the electronics industry, could have an       
                        adverse impact on the Company's operations.
