                                   PROSPECTUS

                        AMERICAN TECHNOLOGY CORPORATION

                           FOR UP TO 1,166,053 SHARES

                                  COMMON STOCK

The shares of common stock, par value $.00001 (the "Common Stock"), of American
Technology Corporation (the "Company") offered hereby represent shares issuable
upon the conversion of certain 6% Subordinated Promissory Notes due March 1,
1999 (the "Notes") and any accrued interest thereon and the exercise of Stock
Purchase Warrants to purchase Common Stock (the "Warrants", which Notes and
Warrants may be referred to herein collectively as the "Convertible
Securities"). Although the Company will not receive any of the proceeds from the
sale of the shares of Common Stock offered hereby, the Company has received
$1,000,000.00 of loan proceeds pursuant to the Notes, an indeterminate amount of
which may be retired upon the conversion of the Notes to shares of Common Stock
of the Company. The Company will receive aggregate funds not exceeding
$250,000.00 upon the exercise of Warrants at an exercise price of $5.00 per
share of Common Stock. See "Selling Security Holders."

The number of shares of Common Stock issuable upon conversion of the Notes is
determined by dividing the aggregate principal amount, plus any accrued interest
at 6% per annum, by the lesser of (i) 85% of the average of the closing bid
prices of the Company's Common Stock each day for the ten trading days
immediately preceding the date of conversion but in no event less than $2.50 per
share, or (ii) for conversions on or after March 1, 1998 the average of the
closing bid prices of the Company's Common Stock each day for the thirty trading
days immediately preceding March 1, 1998 but in no event less than $1.00 per
share, or (iii) $3.50 per share. The minimum number of shares issuable upon
conversion of the $1,000,000 principal amount is 285,715 based on the maximum
conversion price of $3.50 per share. The Company may force conversion of the
Notes at $3.50 per share if the closing bid price of the Common Stock equals or
exceeds $9.00 per share for ten consecutive trading days and certain conditions
are met. The maximum number of shares into which the principal amount of the
Notes can be converted is 400,000 shares until March 1, 1998 and the maximum
from March 1, 1998 to March 1, 1999 (the maturity date) is 1,000,000 shares
(assuming the average closing bid price for the thirty trading days preceding
March 1, 1998 is $1.00 or less). For purposes of this Registration Statement the
Company has computed the maximum number of shares issuable pursuant to the Notes
by dividing the aggregate principal and interest at maturity of $1,116,053 by
the $1.00 floor price or 1,116,053 shares.

The shares of Common Stock registered for resale hereby have been registered
pursuant to the Company's obligations contained in written agreements with the
Selling Security Holders. The Selling Security Holders may elect to sell all, a
portion or none of the Common Stock offered by them hereunder which is only
obtainable through the conversion of all or portion of the Notes or exercise of
all or a portion of the Warrants.

The shares of Common Stock offered hereby may be sold from time to time by
Selling Security Holders named herein under the caption "Selling Security
Holders" through underwriters, dealers, agents, or directly to one or more
purchasers in fixed price offerings, in negotiated transactions, at market
prices prevailing at the time of sale or at prices related to such market prices
or at negotiated prices. This Prospectus also may be delivered in connection
with certain resales as described under "Plan of Distribution." The Company has
agreed to pay certain expenses of registering the shares of Common Stock offered
hereby, including filing fees, legal, accounting and miscellaneous expenses in
connection with registration. All selling and other expenses incurred by the
Selling Security Holders will be borne by such Selling Security Holders. See
"Plan of Distribution."

The shares of Common Stock offered hereby have not been registered under the
blue sky or securities laws of any jurisdiction, and any broker or dealer should
assure itself of the existence of an exemption from registration or effect of
such registration in connection with the offer and sale of such shares.

                                   THE COMPANY

BACKGROUND
American Technology Corporation ("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.

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 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 which is commercializing the EarPHONE for cellular
phone, computer, multi-media and other customers. (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



                                       4
<PAGE>   5
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 12725 Stowe Drive, Poway,
California, and its telephone number is 619-679-2114. Its Internet site is
located at WWW.ATCSD.COM.

CURRENT BUSINESS
The Company is engaged in the development, manufacturing and marketing of
consumer electronic products and electronic 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 1996 and
to date in fiscal 1997 substantially all of the Company's revenues resulted from
the manufacturing and marketing of its "FM Sounds" FM digital scanning ear-radio
and its "AM Sounds" AM ear-radio. The Company seeks to expand its ear-radio
distribution while developing additional technology assets.

Management anticipates that its HyperSonic Sound (HSS) reproduction technology,
currently in development, will become its primary business focus, although there
can be no assurance the Company can successfully exploit this new technology.
HyperSonic Sound is a new method of sound reproduction -- sound is generated in
the air using ultrasonic frequencies, those above the normal range of hearing. A
patent-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. There can be no assurance the Company can
successfully commercialize the HSS technology (see "Risk Factors").

The Company's HSS technology was invented by Elwood G. Norris, a director of the
Company, who manages the Company's research and development and technical
activities and who has invented the Company's products and technologies.
Although the Company has additional products and technologies in various stages
of development, substantially all efforts are focused on the HSS technology and
there can be no assurance additional technologies can be proven or
commercialized.

The Company acquired the basic concepts for the HSS technology (previously
called the Sonic Generator technology) from Mr. Norris in 1992. During fiscal
1996 and fiscal 1997 to date, the Company has 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. To date in 1997 research efforts have focused on
development of custom ultrasonic emitters which management believes will be
required to produce a commercially viable system.

The Company continues to improve its proprietary electronics and is working with
multiple producers of ultrasonic devices to develop 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 1997.

CERTAIN RECENT DEVELOPMENTS
The Company's marketing of the HSS technology continues to evolve as a result of
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 developing product partners, 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.

In accordance with the above strategy, the Company has received non-binding
expressions of interest from more than twenty companies for product applications
including multimedia sound, personal computers, entertainment, telephones,
consumer products, toys, home theater, hearing aids and others. Although the
Company's strategy is to establish closer relationships



                                       5
<PAGE>   6
with these and other companies through specific product collaborations, there
can be no assurance that the 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
anticipates that product license or component supply relationships
(incorporating licensing) will develop as individual products are jointly
designed and developed with product partners in the future.

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

Effective on May 12, 1997, the Company employed Michael E. Spencer, Ph.D., as an
executive officer (Vice President of Engineering of the Company. In this
position he will be the program manager for the HSS technology project. From
1985 to 1992 he was a senior staff engineer at TRW, Inc. and from 1992 to 1994
he was a graduate research assistant at Los Alamos National Laboratories. Since
1989 and until joining the Company he has also been active in his own consulting
company, DSP Group. Mr. Spencer obtained his Masters in Electrical Engineering
from the Georgia Institute of Technology in 1985 and a Ph.D. in Electrical
Engineering from the University of Southern California in 1995.

                                  RISK FACTORS

The Common Stock offered hereby is speculative and involves a high degree of
risk and should be considered only by persons who can afford the loss of their
entire investment. In addition to the other information included elsewhere in
this Prospectus, prospective investors should give careful consideration to the
following factors before purchasing any shares of the Common Stock offered
hereby. This Prospectus includes forward-looking statements which include risks
and uncertainties. The Company's actual results could differ materially from
those anticipated as a result of a variety of factors, including those set forth
in the following risk factors and elsewhere in this Prospectus.

HISTORY OF LOSSES; ABSENCE OF PROFITABILITY; AND EXPECTATION OF FUTURE LOSSES
The Company has an accumulated deficit of $2,827,566 at March 31, 1997 with
increasing net losses of $801,629 for the six months ended March 31, 1997,
$560,448 for fiscal 1996 and $368,201 for fiscal 1995. 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.

INSUFFICIENT FUNDS FOR THE NEXT TWELVE MONTHS; ADDITIONAL CAPITAL REQUIREMENTS;
AND POSSIBLE CASH SHORTAGE
Based on the current rate of expenditures and anticipated additional
expenditures, the Company does not have sufficient funds for the next twelve
months and will require funds from the sale of products or licensing or sale of
technology or from other sources or will be required to scale back or curtail
certain activities. The Company has not achieved profitability and has been
required to raise substantial amounts of capital to support its development
activities and operations. As the Company continues to focus on its new HSS
technology, it will continue to be dependent on outside financing sources.

From its reorganization in January 1992 and through March 31, 1997, the Company
has financed its operations primarily through the sale of common equity and
convertible notes and proceeds from the sales of shares in Norris
Communications, Inc. (NCI). During the six months ended March 31, 1997, the
Company obtained $332,600 from the exercise of stock options and warrants and
$1,000,000 from convertible notes.

Other than the NCI shares valued at approximately $91,000 at March 31, 1997 and
cash on hand, 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 Company could be required to curtail research and
development expenditures if there is a cash shortage. 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. At the current rate of expenditures, the Company
will require significantly improved gross margins from product sales, margins
from new technologies or additional funds for the next twelve months aggregating
an estimated $500,000. This estimate is subject to significant variability due
to management decisions and outside factors. Potential sources of any such
required funds may



                                       6
<PAGE>   7
include the sale of additional NCI shares, bank financing, other debt financing,
and additional offerings of the Company's equity securities. There can be no
assurance that any funds will be available from these or other potential sources
and the lack of such capital could have a material adverse affect on the
Company's business.

FUTURE DEPENDENT ON MARKET ACCEPTANCE OF THE COMPANY'S HSS TECHNOLOGY
The future of the Company is largely dependent upon the success of the Company's
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. Because the HSS technology currently represents the
Company's primary technology focus, if the HSS technology is not successful, the
Company's business, financial condition and results of operations would be
materially and adversely affected.

HSS TECHNOLOGY IN DEVELOPMENT; NO ASSURANCE OF COMPLETION; MAY BE SUBJECT TO
DELAYS
The Company's 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 its
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, 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. 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.

HSS TECHNOLOGY WILL FACE 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.

NEW TECHNOLOGY FACES MANY BARRIERS AND RISKS
The introduction of new technology, such as the HSS technology, that is targeted
for wide use often faces barriers to commercialization and risks many that
cannot presently be identified. The HSS technology employs ultrasonics and
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 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. In accordance with this strategy, the
Company has received non-binding expressions of interest from more than twenty
companies for product applications including multimedia sound, personal
computers, entertainment, telephones, consumer products, toys, home theater,
hearing aids and others. Although the Company's strategy is to establish closer
relationships with these and other companies through specific product
collaborations, there can be no assurance that the 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 not only on the Company's continued
relationships with these parties, but also on its ability to enter into
additional strategic arrangements with new partners on commercially reasonable
terms. Any future



                                       7
<PAGE>   8
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.

PRODUCTS IN DEVELOPMENT SUBJECT TO MANY RISKS
The markets for the Company's existing and future products and technologies are
characterized by rapidly changing technology, evolving industry standards,
frequent new product introductions and enhancements. The successful development
and commercialization of new products and technologies involve many risks,
including the correct and timely identification of new opportunities, the
successful completion of the developmental process, the retention and hiring of
appropriate research and development personnel, establishment of marketing and
distribution and other risks. The life cycle and demand for new products and
technologies is difficult to predict and is subject to the effects of
competition, technological change, price changes and other factors all of which
could have a material adverse effect on the Company's operations, business and
financial condition.

PRODUCT SALES SUBJECT TO SIGNIFICANT VARIABILITY; INSUFFICIENT TO SUPPORT
OPERATIONS
The sales of the Company's existing ear-radio products are subject to
significant quarterly and seasonal variability. The Company has been in the past
and may in the future be reliant on a limited number of customers, the loss of
which could have an adverse effect on operating results. To date the Company's
sales have consisted almost entirely of ear-radio sales. The Company has been
unable to obtain sufficient volumes and margins to support operations and
management does not believe sufficient ear-radio product sales can be achieved
to achieve profitable operations at the current level of expenditures.
Accordingly, the Company will be reliant on revenues from new products or
technologies to achieve profitable operations. There can be no assurance the
Company can exploit new technologies.

EAR RADIO ASSEMBLY DEPENDENT ON SUBCONTRACTOR; 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 a
foreign subcontractor. 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 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 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.

PATENTS AND PROPRIETARY RIGHTS SUBJECT TO UNCERTAINTY
The Company has two U.S. patents on ear-radios which it relies on to protect its
market position in the U.S. The Company has three 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 or 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 Company's 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.

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 have "key person" life insurance
policies on any other person. The loss of the services of Mr. Norris 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.

MANAGEMENT OF GROWTH
Depending on the extent of its future growth, if any, the Company may experience
a significant strain on its management, operational and financial resources. The
Company's ability to manage its growth effectively may require it to continue to
implement and improve its operational and financial systems and may require the
addition of new management personnel. The failure of the Company's management
team to effectively manage growth, should it occur, could have a material
adverse impact on the Company's results of operations.

GENERAL CONFLICTS OF INTEREST DUE TO PART-TIME MANAGEMENT
Mr. Robert Putnam (President and CEO) and Mr. Elwood G. Norris (Director and
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
significant attention and will continue to do so notwithstanding the fact that
management time should be devoted to the Company's business. Mr. Putnam devotes
approximately 70% of his time and Mr. Norris devotes approximately 20-30 hours
per week to the Company. These management members generally expect to devote
time to the Company only on an as-needed basis over the next twelve months.

Certain conflicts of interest now exist and will continue to exist between the
Company and its officers and directors due to the fact that each has other
employment or business interests to which he devotes some attention. 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.

SPECIAL CONFLICTS OF INTEREST DUE TO RELATIONSHIP OF EXECUTIVES
The Company's President and CEO, Mr. Robert Putnam, also acts as Secretary of
Norris Communications, Inc. (NCI), a company of which Mr. Norris is Chairman and
CEO. Mr. Norris is also a significant shareholder and director of the Company.
As a result of these relationships, Mr. Putnam is subordinate to Mr. Norris. The
possibility exists that these relationships will affect Mr. Putnam's
independence as a director of the Company.

INDEMNIFICATION OF OFFICERS, DIRECTORS AND OTHERS
The Company's Certificate of Incorporation provides for the indemnification of
its officers, directors, employees and agents, under certain circumstances,
against attorney's fees and other expenses incurred by them and judgments
rendered against them in any litigation to which they become a party arising
from their association with or activities on behalf of the Company. The Company
may also bear the expenses of such litigation for any of its officers,
directors, employees or agents, upon their promise to repay such sums if it is
ultimately determined that they are not entitled to indemnification. This
indemnification policy could result in substantial expenditures by the Company
which it may be unable to recoup even if so entitled.

EXCLUSION OF DIRECTOR LIABILITY
The Company's Certificate of Incorporation excludes personal liability on the
part of its directors to the Company for monetary damages for breach of
fiduciary duty, except in certain specified circumstances. Accordingly, the
Company will have a much more limited right of action against its directors than
otherwise would be the case. This exclusionary provision does not affect the
liability of any director under federal or applicable state securities laws.

NO ACTIVE TRADING MARKET; MARKET VOLATILITY
The Company's shares are traded on the OTC Electronic Bulletin Board, a
screen-based trading system operated by the National Association of Securities
Dealers, Inc. Securities traded on the Bulletin Board are, for the most part
thinly traded and are subject to special regulations not imposed on securities
listed or traded on the National Association of Securities Dealers Automated
Quotation ("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, increasing the risk of ownership to
investors. Historically, the 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.

SHARES ELIGIBLE FOR FUTURE SALE
As of the date of this Prospectus, the Company had outstanding 9,513,467 shares
of Common Stock. As of such date, in addition to the securities described in
this Prospectus, the Company has outstanding stock options to purchase 871,500
shares of its Common Stock and warrants to purchase an additional 450,000
shares, some subject to vesting. If all of the shares issuable upon exercise of
these options and warrants or upon conversion of the Notes and exercise of the
Warrants described herein are issued, the Company will have additional shares of
Common Stock outstanding, most of which will be eligible for resale into the
public markets. The sale of such shares in the public markets could have a
material adverse effect on the trading price of the Company's Common Stock.

NO DIVIDENDS WILL BE PAID IN FORESEEABLE FUTURE
The Company does not contemplate paying cash dividends in the foreseeable
future. Future dividends will depend on the Company's earnings, if any, and its
financial requirements.

NO ANTI-TAKEOVER MEASURES
Neither the Company's charter nor its bylaws contain any provision which is
designed or intended to serve as an anti-takeover measure or which is intended
to entrench Management or discourage mergers or other business combinations
involving the Company.

                                 USE OF PROCEEDS

All proceeds from any sale of shares of Common Stock offered by the Selling
Security Holders will be received by the Selling Security Holders and not by the
Company. The proceeds to the Company from the exercise of the Warrants not to
exceed $250,000, if any, will be used for general corporate purposes.

                            SELLING SECURITY HOLDERS

An aggregate of up to 1,166,053 shares of Common Stock are being offered for
resale by certain shareholders of the Company. Up to 1,116,053 of those shares
are issuable upon conversion by the holders of $1,000,000 aggregate principal
amount of Notes and accrued interest thereon. Up to 50,000 shares are issuable
upon exercise of Warrants held by the holders of the Notes. All shares, to the
extent they are being offered, are being offered for the account of the
following shareholders and their donees or pledgees (the "Selling Security
Holders").

The following table sets forth certain information with respect to the Selling
Security Holders for whom the Company is registering the Common Stock for resale
to the public, including: (i) beneficial ownership of common stock as of the
date of this prospectus, (ii) the principal amount of Notes owned by each
Selling Security Holder, (iii) the maximum number of shares issuable upon
conversion of the Notes and accrued interest thereon, (iv) the number of shares
issuable upon exercise of Warrants, (v) the percentage of class owned (assuming
the maximum number of shares were issued upon conversion); and (vi) the maximum
number of shares offered by each Selling Security Holder (assuming the maximum
number of shares were issued upon conversion). The Company has no knowledge of
the intentions of any Selling Security Holder to actually sell any of the shares
listed under the columns "Maximum Shares Issuable Upon Conversion" or "Shares
Issuable Upon



                                       10

Exercise of Warrants." There are no material relationships between any of the
Selling Security Holders and the Company other than as disclosed below.

1) No information is given with respect to beneficial ownership after the
offering because the principal and interest amount of Notes that will be
converted into Common Stock, as well as the number of shares issuable upon
conversion, is currently indeterminate.

2) The number of Common Shares reported above as beneficially owned by each
Selling Security Holder is based solely on a review of a list of the Company's
shareholders prepared by the Company's transfer agent and registrar. None of
these shares are being registered pursuant to this prospectus. (See the third
column and the following footnote for the maximum shares issuable upon
conversion of the Notes).

3) Assumes conversion based on the lowest conversion price possible of 100
percent of the principal amount of the Notes and the maximum accrued interest at
6% per annum, simple interest, from the issue date of March 25, 1997 to the date
of maturity of March 1, 1999. The Company has computed the maximum number of
shares issuable pursuant to the Notes by dividing the aggregate principal and
interest at maturity of $1,116,053 by the $1.00 floor price or 1,116,053 shares.
The actual number of shares issuable on conversion may be less. The number of
shares of Common Stock issuable upon conversion of the Notes is determined by
dividing the aggregate principal amount, plus any accrued interest at 6% per
annum, by the lesser of (i) 85% of the average of the closing bid prices of the
Company's Common Stock each day for the ten trading days immediately preceding
the date of conversion but in no event less than $2.50 per share, or (ii) for
conversions on or after March 1, 1998 the average of the closing bid prices of
the Company's Common Stock each day for the thirty trading days immediately
preceding March 1, 1998 but in no event less than $1.00 per share, or (iii)
$3.50 per share. The maximum number of shares that the principal amount of the
Notes can be converted is 400,000 shares until March 1, 1998 and the maximum
from March 1, 1998 to March 1, 1999 (the maturity date) is 1,000,000 shares
(assuming the average closing bid price for the thirty trading days preceding
March 1, 1998 is $1.00 or less). The minimum number of shares issuable upon
conversion of the $1,000,000 principal amount is 285,715 based on the maximum
conversion price of $3.50 per share.

4) Assumes conversion of 100 percent of the Warrants granted to each Note holder
based on the exercise price of $5.00 per share.

5) Assumes issuance of the maximum shares on conversion of the Notes at the
lowest conversion price and the exercise of 100 percent of the Warrants.

6) Represents maximum shares over current outstanding shares as of the date of
this prospectus of 9,513,467. An asterisk (*) represents less than 1%.

                              PLAN OF DISTRIBUTION

The purpose of this Prospectus is to permit the Selling Security Holders, if
they desire, to offer and sell up to 1,166,153 shares of Common Stock (the
"Selling Security Holder Shares") at such times and at such places as the
Selling Security Holders choose.

The decision to convert the Notes into shares, to exercise the Warrants, or to
sell any shares, is within the sole discretion of the holders thereof. There can
be no assurance that any of the Notes will be converted or any of the Warrants
will be exercised, or any shares will be sold by the Selling Security Holders.

The Selling Security Holder Shares offered hereby is being sold by the Selling
Security Holders acting as principal for their own accounts. The distribution of
the Shares is not subject to any underwriting agreement. The Company expects the
Selling Security Holders will sell the Shares covered by this Prospectus through
customary brokerage channels, either through broker-dealers acting as
principals, who may then resell the shares in the over-the-counter market, or at
private sales or otherwise, at market prices prevailing at the time of sale, at
prices related to such prevailing market prices or at negotiated prices. The
Selling Security Holders may effect such transactions by selling shares through
broker-dealers, and such broker-dealers will receive compensation in the form of
commissions from the Selling Security Holders and/or the purchasers of the
Shares for whom they may act as agent (which compensation may be in excess of
customary commissions). The Selling Security Holders and any broker-dealers that
participate with such Selling Security Holders in the distribution of the Shares
may be deemed to be underwriters and any commissions received by such
broker-dealers and any profit on resale of the Shares sold by them might be
deemed to be underwriting discounts or commissions under the



                                       12
<PAGE>   13
Securities Act. In addition, any Selling Security Holder Shares covered by this
Prospectus that qualify for sale pursuant to Rule 144 under the Securities Act
may be sold under Rule 144 rather than pursuant to this Prospectus.

The Selling Security Holders are not restricted as to the price or prices at
which they may sell the Shares. Sales of Shares at less than market prices may
depress the market price of the Company's Common Stock. Moreover, the Selling
Security Holders are not restricted as to the number of shares which may be sold
at any one time, and it is possible that a significant number of shares could be
sold at the same time.

Under applicable rules and regulations under the Exchange Act, any person
engaged in a distribution of the Shares may not simultaneously engage in market
making activities with respect to the Common Stock for a period of nine business
days prior to the commencement of such distribution. In addition and without
limiting the foregoing, the Selling Security Holders will be subject to
applicable provisions of the Exchange Act and the rules and regulations
thereunder, including without limitation rules 10b-6 and 10b-7, which provisions
may limit the timing of purchases and sales of the shares by the Selling
Security Holders.

The Company will not receive any proceeds from any sales of the Selling Security
Holder Shares, but will receive the proceeds from the exercise of the Warrants
held by the Selling Security Holders, which proceeds, if any, will be used for
general corporate purposes.

In connection with the registration by the Company, the Company shall use its
best efforts to prepare and file with the Commission such amendments and
supplements to the registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
to comply with the provisions of the Securities Act with respect to the
disposition of the shares covered by the registration statement for the period
required to effect the distribution of such shares.

The Company is paying certain expenses (other than commissions and discounts of
underwriters, dealers or agents) incident to the offering and sale of the Shares
to the public, which are estimated to be approximately $8,000. If the Company is
required to update this Prospectus during such period, it may incur additional
expenses in excess of the amount estimated above.

In order to comply with certain states' securities laws, if applicable, the
shares will be sold in such jurisdictions only through registered or licensed
brokers or dealers. In certain states the Shares may not be sold unless they
have been registered or qualify for sale in such state or an exemption from
registration or qualification is available and is complied with.

                            DESCRIPTION OF SECURITIES

The Company is authorized to issue 20,000,000 shares of Common Stock, $.00001
par value per share. As of the date of this Prospectus there were 9,513,467
shares outstanding. The holders of Common Stock are entitled to one vote for
each share held. The affirmative vote of a majority of votes cast at a meeting
which commences with a lawful quorum is sufficient for approval of most matters
upon which shareholders may or must vote, including the questions presented for
approval or ratification at the Annual Meeting. However, removal of a director
from office or repeal of the certificate of incorporation in its entirety
require the affirmative vote of a majority of the total voting power for
approval, and certain other matters (such as shareholder amendment of the
bylaws, and amendment, repeal or adoption of any provision inconsistent with
provisions in the certificate of incorporation regarding indemnification of
directors, officers and others, exclusion of director liability, and the
Company's election not to be governed by statutory provisions concerning
business combinations with interested shareholders) require the affirmative vote
of two-thirds of the total voting power for approval. Common Shares do not carry
cumulative voting rights, and holders of more than 50% of the Common Stock have
the power to elect all directors and, as a practical matter, to control the
Company. Holders of Common Stock are not entitled to preemptive rights, and the
Common Stock is not subject to redemption.

The Company's board of directors is authorized to issue 5,000,000 shares of
undesignated preferred stock, $.00001 par value, without any further action by
the stockholders. The board of directors may also 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.
There are currently no shares of preferred stock issued and outstanding.

The Company has not paid any cash dividends to date, and no cash dividends will
be declared or paid on the Common Shares in the foreseeable future. Payment of
dividends is solely at the discretion of the Company's board of directors.

                 INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

The Company's certificate of incorporation and bylaws provide broadly for the
indemnification of the directors and officers of the Company for certain
liabilities and costs incurred by them in connection with the performance of
their duties. This indemnification may include indemnification for liabilities
arising under the Securities Act.

Insofar as indemnification for liabilities arising under the Securities Act may
be permitted to directors, officers or persons controlling the Company pursuant
to the foregoing provisions, the Company has been informed that in the opinion
of the Securities and Exchange Commission, such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable.
