Overview

American Technology Corporation develops and delivers innovative directed acoustic products that beam, focus and control
sound over short and long distances. By placing sound only where needed, we not only enhance many typical speaker applications, but we offer novel sound applications that conventional speakers cannot achieve. We offer a variety of directional sound
products for applications ranging from focusing digital signage advertising on a customer at ten feet to protecting assets by communicating with and deterring threats over distances greater than 1,000 meters. Since 1996, we have been at the
forefront developing new acoustic innovations to project, focus, shape and control sound and we believe we have established a significant competitive advantage in our principal markets. Our Long Range Acoustic DeviceTMor LRAD® pioneered a new worldwide market for directional long-range acoustic hailing and warning devices (AHDs) capable of communicating with authority and clarity over 1,000
meters. We also believe we are the leader in commercializing parametric speakers, branded as HyperSonic® sound
or HSS®.

We have 43 patents issued worldwide covering our various sound technologies, of which 40 are patents issued in the United States. We also have 26 pending patent applications worldwide, of which 15 are
pending patent applications in the United States.

Technology and Products

Our three major technology platforms and related products are:

LRAD®

Our Long Range Acoustic
Device, or LRAD, is a technology breakthrough that creates a directed acoustic beam using minimal power to communicate at operational ranges with authority and superior intelligibility even in high ambient noise environments. LRAD hailing,
notification and warning systems feature a 15 to 30 degree acoustic beam and a range of over 1,000 meters. The LRAD also features a rugged construction that allows the product to meet the stringent environmental requirements of military
applications. LRAD can emit powerful voice commands, prerecorded messages in multiple languages or deterrent tones to create a safety zone allowing operators to determine the intent, influence the behavior and gain compliance from approaching
vessels, vehicles or personnel. LRAD was developed for the U.S. Navy to fulfill a capability gap identified after the USS Cole attack in 2000 and has been deployed by the U.S. Army, Navy, Marines and Coast Guard, as well as commercial vessels and
public safety entities around the globe since the spring of 2003.

##### Table of Contents

We have expanded our market penetration by developing
new products to meet customer operational needs. In fiscal 2007, we introduced the LRAD-R, a remotely-controlled device that can be operated from a separate command-control center. In fiscal 2008, we introduced our LRAD-X® product line. The LRAD-X product line features improved voice intelligibility and is available in a number of
packages and form factors that meet the militarys stringent environmental requirements. Our LRAD-X product line provides a complete range of systems from single man portable to permanently installed, remotely operated infrastructure
protection. Our LRAD products have been competitively selected over other commercially available systems by the U.S. military. The LRAD-X series includes:



| |  |  | LRAD 1000Xselected by the U.S. Navy as its AHD for its Block 0 program of the Shipboard Protection Systemcan be manually operated to
provide long distance hailing and warning with highly intelligible communication.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | LRAD 500Xselected by the U.S. Navy and U.S. Army as their AHD for small vessels and vehiclesis lightweight and can be easily transported to
provide security personnel long-range communications and a highly effective hailing and warning capability where needed.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | LRAD 300Xour newest addition to our LRAD product line, introduced in fiscal 2009is a compact solution offering highly intelligible
mid-range communications in a lightweight, rugged package for use on small vessels and manned and unmanned vehicles and aircraft.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | LRAD 100X is a self-contained, battery powered portable system designed for use in a variety of mass notification, law enforcement and commercial
security applications. It is ideally suited for short-range perimeter security and communications.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | LRAD-RXTMis our prescription for remotely controlled security. It enables system operators to detect and communicate with an
intruder over long distances. LRAD-RX features an LRAD 1000X emitter head and an integrated internet protocol (IP)-addressable full pan and tilt drive system for precise aiming and tracking. LRAD-RX reduces manpower and false alarms while providing
an intelligent, cost-effective security solution. The LRAD-RX can be operated remotely from anywhere across a Transmission Control Protocol IP (TCP/IP) network enabling system operators to respond to security threats from a safe remote environment.
The LRAD-RX is aimed and controlled by our proprietary pan and tilt drive system. We designed and engineered this pan and tilt drive system during fiscal 2008 to meet the demanding specifications of customers that deploy these devices on large
vessels, offshore oil and other platforms. The LRAD-RX can be integrated with a number of other sensors (radar, cameras, etc.) creating a fully integrated unmanned perimeter security solution.

HSS®

Our HyperSonic sound,
or HSS, proprietary parametric speaker technology creates sound in the air. Sound is generated along an air column using ultrasonic frequencies above the normal range of hearing. The HSS sound beam is highly directional and maintains
sonic clarity and intelligibility. Our HSS products are compatible with any media player but beam sound where you want it and nowhere else. We believe our substantial intellectual property portfolio and pioneering HSS products support our leadership
position in the field of parametric non-linear acoustics for sound reproduction. We currently offer our HSS 450 speaker system with a 5 by 10 inch emitting surface area.

SoundSaber®

Our SoundSaber thin
film magnetic speaker technology, the predominant product from our NeoPlanar speaker line, provides high clarity throughout the audio range for emergency and mass notification, public address and high-end sound applications. SoundSaber products are
based on our proprietary technology incorporating a thin film magnetic speaker that produces sound of high quality, low distortion and high

Strategy

We believe we
have been instrumental in developing a market and increasing demand for acoustic hailing devices in a number of business segments. We are building on our leadership position in the field of directed or focused sound for both short-range and
long-range communication with high clarity. Our overall strategy is to offer an increasing variety of directed sound and other products for an increasing range of applications. In executing our strategy, we use direct sales to larger end-users,
system integrators and defense-related companies and we are building a worldwide distribution channel consisting of partners and resellers that have significant expertise and experience selling integrated communications solutions into our various
target markets.

A major initiative for fiscal 2010 is to continue to accelerate revenue growth by increasing direct sales to
military, larger commercial and defense-related companies desiring to use our directed sound technology in their integrated product offerings. Our senior executive, sales and marketing personnel focus primarily on the government, military, homeland
and international security, private and commercial security and maritime, wildlife preservation and control and digital signage markets. In 2010, we intend to continue our focus on these markets and to expand our product offerings into the
clean/alternative energy market where our products have proven successful in preserving wildlife and protecting assets, including wind farms and solar panels. We continue to focus on expanding and strengthening domestic and international sales
channels by adding key channel partners, distributors and dealers. Our goal is to continue to expand market penetration for our LRAD products. We are also working to expand markets for our HSS and SoundSaber products for use in a wide range of
commercial applications and mass notification systems.

Our research and development strategy is to continue to develop
innovative directed acoustic solutions and to design new products for introduction into our target markets. In 2008, we made significant improvements to the performance and quality of our existing directed sound products and introduced our new line
of LRAD-X

products. The introduction of our redesigned and reengineered product line led to a 41% increase in 2009 revenues when compared to 2008 revenues. We have ongoing development efforts to further
improve our products performance and quality. We also engage in ongoing value engineering to reduce the cost and simplify the manufacturing of our products.

Manufacturing and Suppliers

Manufacturing. We believe maintaining
quality manufacturing capacity is essential to the performance of our products and the growth of our business. Our technologies are different from mass produced sound transducer designs, and our manufacturing and assembly involves new processes and
materials. We contract with third party suppliers to produce various components and sub-assemblies. At our San Diego facility, we complete the final assembly of, and test and ship, our products for both commercial and government systems. We have
refined our internal business processes to improve how we design, test and qualify product designs. We continue to implement rigorous manufacturing and quality processes to track production and field failures. We have also implemented
third-party testing and certification of our products ensuring that they meet our military customer specifications. We have developed custom manufacturing equipment used to automate the production of key sub-assemblies reducing the labor
component and permitting higher volume production. We implement design and component changes periodically to reduce our product costs, improve product reliability and improve operating margins.

Suppliers. Our products have a large number of components and sub-assemblies produced by outside suppliers. In addition, for some of
these items, we qualify only a single source, which can magnify the risk of shortages and decrease our ability to negotiate with our suppliers on the basis of price. In particular, we depend on our HSS piezo-film supplier to provide expertise and
materials used in our proprietary HSS emitters, and we rely on one supplier of a key component for our LRAD products. If shortages occur, or if we experience quality problems with suppliers, then our production schedules could be significantly
delayed or costs significantly increased, which could in turn have a material adverse effect on our financial condition, results of operation and cash flows.

Sales and Marketing

We market and sell products and services through our
sales force based in San Diego, California, Maine and Washington. Our corporate and administrative offices are located in San Diego, California.

We make direct sales to large end-users and defense-related companies. We use independent representatives to assist us in these efforts. We also use a channel distribution model in which we sell our
products directly to a small network of worldwide independent resellers and system integrators who then sell our products (or our products integrated with other systems) to end-user customers. We are focusing our internal business development
resources on building relationships with defense integrators and other large, direct customers.

We have established a
reputation for providing high quality, innovative sound solutions and have increased our brand recognition for LRAD and HSS. We actively promote our brands on our products and we intend to continue to increase the use of our trademarks throughout
our product distribution chain and believe growing brand awareness will assist in expanding our business.

Customer Concentration

For the fiscal year ended September 30, 2009, revenues from Anchor Innovation, Inc. accounted for 24% of revenues.
For the fiscal year ended September 30, 2008, revenues from two customers, ADS, Inc. and Advanced Integrated Systems accounted for 17% and 10% of revenues, respectively, with no other single customer accounting for more than 10% of revenues.
Anchor Innovation, Inc. is a representative, primarily to end users in the U.S. Navy. ADS, Inc. is a reseller to end users in various branches of the military such as the U.S. Navy, U.S. Marine Corps, U.S. Army, the Department of Homeland Security
and international customers.

Our revenues have to date relied on a few major customers. The loss of any customer
could have a material adverse effect on our financial condition, results of operations and cash flows. Our goal is to diversify sound technology revenues in future periods.

Our order backlog for products that are deliverable in the next 12 months was approximately $1,112,000 at September 30, 2009 compared
to $351,000 at September 30, 2008. The amount of backlog at any point in time is dependent upon scheduled delivery dates by our customers and product lead times. Backlog orders are subject to modification, cancellation or rescheduling by our
customers.

Warranties

We generally warrant our products to be free from defects in materials and workmanship for a period up to one year from the date of purchase. The warranty is generally a limited warranty, and in some
instances imposes certain shipping costs on the customer. To date, we have been providing direct warranty service, but in the future we may establish warranty service through OEM customers or others. Some of our agreements require OEM customers to
stock certain quantities of product for use as warranty replacements. Our international market warranties are generally similar to the warranties we offer in the U.S. market.

As our products become more complex, we are providing service and maintenance agreements and extended warranty contracts at market rates as
an additional source of revenue and to provide increased customer satisfaction.

Our technologies and products compete with those of other companies. The consumer, commercial and government audio industry markets are
fragmented and competitive and include numerous manufacturers with audio products that vary widely in price, quality and distribution channels. Manufacturers of consumer and commercial speakers include Harman International, Boston Acoustics and many
others. Many of our present and potential future competitors have, or may have, substantially greater resources to devote to further technological and new product developments. We believe we compete primarily on the originality of our concepts, the
uniqueness and quality of our technology and designs, the ease and cost of manufacturing and implementing our technologies, the ability to meet customer needs, the strength of our intellectual property and the strength of licensee and contract
supply arrangements. We may not, however, be competitive with the existing or future products, technologies or services of our competitors.

We believe our LRAD products are the leading acoustic hailing and warning products in the market for military and commercial applications. The broad category of government audio industry speakers includes
competitors such as IML Sound Commander and others. We do not believe these competitors have achieved significant market penetration in the government or commercial directed hailing markets to date. We believe our LRAD product line has demonstrated
acceptance and has performed extremely well in harsh environments and can continue to compete on the basis of technical features, performance, ease of use and cost.

We believe HSS is the leading parametric speaker with little direct competition to date. Companies such as Brown Innovations and others have employed domes and other techniques to try to focus or contain
sound for directed sound applications such as point-of-sale. We do not believe these methods are directly competitive to HSS in ease of use, cost and performance. Although others have attempted to use parametric speaker concepts to produce sound, we
do not believe they have progressed to the point of cost-effective and directly competitive commercial products as compared to HSS. Holosonic Research Labs produces a parametric speaker called the Audio Spotlight. Sennheiser Electronics has
announced a parametric speaker product called the AudioBeam Master and Mitsubishi has a parametric speaker product which is sold in Japan. These companies employ electrostatic and piezoelectric emitter devices, which we believe have lower output and
are more expensive than our proprietary emitters. However, these parametric speaker competitors or others may introduce products with features and performance competitive to our products.

We believe our SoundSaber technology is novel and has distinct market attributes compared to
existing and competing flat panel and traditional speaker designs. We believe our SoundSaber technology produces high intelligibility and reliability for a range of consumer, commercial and government applications. Other companies that compete in
the flat panel market include, but are not limited to high-end electrostatic flat panel manufacturers such as Martin Logan and others, and NXT Plc and its licensees employing the NXT flat panel technology, which uses a magnetic actuator to produce
vibrations over a rigid panel. We are not aware of companies offering flat panel technology comparable to our SoundSaber products, but others may introduce products with competitive features and performance.

We intend to continue our strategy to aggressively seek patent protection for our intellectual property.

There are also continuing attempts by a large number of competitors to innovate new methods of sound reproduction to overcome limitations of
traditional loudspeakers. It is possible that alternate technologies and systems that would be directly competitive with our sound technology have been developed but are unknown to us. Such systems may also currently be in development, and may be
developed by others in the future.

Seasonality

Government business tends to be seasonal due to government procurement cycles, with the quarter ending September 30 usually producing relatively higher sales and the quarter ending December 31
usually producing relatively lower sales. We have not experienced any significant seasonality trends to date, but we may experience increased seasonality in the future.

Government Regulation

We are subject to a variety of government laws and
regulations that apply to companies engaged in international operations, including, among others, the Foreign Corrupt Practices Act, U.S. Department of Commerce export controls, local government regulations and procurement policies and practices
(including regulations relating to import-export control, investments, exchange controls and repatriation of earnings). We maintain controls and procedures to comply with laws and regulations associated with our international operations. If we are
unable to remain compliant with such laws and regulations, our business may be adversely affected.

Some of our electronic
products are subject to various regulations and are required to meet the specifications of agencies such as the Federal Communications Commission (FCC). We believe we are in substantial compliance with all current applicable regulations, and that we
have all material governmental permits, licenses, qualifications and approvals currently required for our operations.

Our HSS
technology is subject to control under the Radiation Control for Health and Safety Act of 1968, and the associated regulations promulgated by the Food and Drug Administration (FDA), as an electrical emitter of ultrasonic vibrations. Under the terms
of such regulations, we provided an abbreviated report to the FDA describing the technology. The FDA may respond to the report and request changes or safeguards to the technology, but it has not done so to date. We will also be required to notify
the FDA in writing should an HSS product be found to have a defect relating to safety of use due to the emission of electronic product radiation. We do not believe our HSS technology poses any human health risks. However, it is possible that we, or
one of our OEM customers or licensees, could be required to modify the technology, or a product incorporating the technology, to comply with requirements that may be imposed by the FDA.

Our products are being produced to standard product safety requirements for sale in the United States and to similar requirements for sale
in Europe and Canada. We expect to meet the electrical and other regulatory requirements for electronic systems or components we sell throughout the world.

Intellectual Property Rights and Proprietary Information

We operate in an industry where innovations, investment in new ideas and protection of resulting intellectual property rights are important
to success. We rely on a variety of intellectual property protections for our products and technologies, including patent, copyright, trademark and trade secret laws and contractual obligations, and we pursue a policy of vigorously enforcing such
rights.

We have a substantial base of intellectual property assets. We have 43 patents issued worldwide, of which 40 are in
the U.S. We also have approximately 26 patents pending worldwide, of which 15 are in the U.S. on our proprietary sound technologies. Our issued patents expire between 2010 and 2025. We intend to file other sound technology patent applications. We
target our patent coverage to provide protection in the major manufacturing and commercial centers of the world. In addition to such factors as innovation, technological expertise and experienced personnel, we believe that a strong patent position
is important to compete effectively in the sound reproduction industry.

We have an ongoing policy of filing patent
applications to seek protection for novel features of our products and technologies. Prior to the filing and granting of patents, our policy is to disclose key features to patent counsel and maintain these features as trade secrets prior to product
introduction. Patent applications may not result in issued patents covering all important claims and could be denied in their entirety.

We invest management, legal and financial resources toward our technology patents. The electronics industry is characterized by frequent litigation regarding patent and other intellectual property rights.
Others, including academic institutions and competitors, hold numerous patents in electronics and sound reproduction. Although we are not aware of any existing patents that would materially inhibit our ability to commercialize our sound technology;
others may assert claims in the future. Such claims, with or without merit, may have a material adverse effect on our financial condition, results of operations or cash flows.

The validity of our existing patents has not been adjudicated by any court. Competitors may bring legal action to challenge the validity of
our existing or future patents or may attempt to circumvent the protection provided by such patents. The failure to obtain patent protection or the loss of patent protection on our existing and future technologies or the circumvention of our
patents by competitors could have a material adverse effect on our ability to compete successfully.

We generally take
advantage of the Patent Convention Treaty procedures for patent protection in foreign countries. This procedure is more cost efficient, but results in a delay in the application and issuance of foreign patents; however, any resulting foreign
patents, if and when issued, enjoy the same priority date as U.S. counterparts.

We also file for trade
name and trademark protection when appropriate. We are the owner of federally registered trademarks including HYPERSONIC®, HYPERDIRECTIONAL®, HSS®, LRAD®, LRAD-X®, PMT®, SOUNDSABER® and SHAPING THE FUTURE OF SOUND®. Trade names or trademarks may not be successfully maintained, defended or protected.

Our policy is to enter into
nondisclosure agreements with each employee and consultant or third party to whom any of our proprietary information is disclosed. These agreements prohibit the disclosure of confidential information to others, both during and subsequent to
employment or the duration of the working relationship. These agreements may not prevent disclosure of confidential information or provide adequate remedies for any breach.

We are obligated to pay a minimum of $1.00 per unit royalty on one electronic component for our HSS product. The cost of this royalty has
been immaterial in the fiscal years ended September 30, 2009 and 2008.

Research and Development

The sound reproduction market is subject to rapid changes in technology and designs with frequent improvements and new product introductions.
We believe our future success will depend on our ability to enhance and improve existing technologies and to introduce new technologies and products on a competitive basis. Accordingly, we have in the past, and we expect in the future, to engage in
significant research and development activities.

For the fiscal years ended September 30, 2009 and 2008, we spent
approximately $2.1 million and $3.4 million, respectively, on company-sponsored 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 currently owned technologies or in other areas.

|Item 1A. | Risk Factors.
|-------- | -------------

An
investment in our company involves a high degree of risk. In addition to the other information included in this report, you should carefully consider the following risk factors in evaluating an investment in our company. You should
consider these matters in conjunction with the other information included or incorporated by reference in this report. Our results of operations or financial condition could be seriously harmed, and the trading price of our common stock may decline
due to any of these or other risks.

We have a history of net losses and we may not achieve or sustain profitability.

We have a history of operating losses and our ability to achieve future profitability is dependent on a variety of factors, many outside
our control. At September 30, 2009 we had an accumulated deficit of $74,904,164. We need to generate additional revenue to be profitable in future periods. Failure to achieve profitability, or sustain profitability if achieved, may require us
to raise additional funding which could have a material negative impact on the market value of our common stock.

We may need additional
capital for growth.

We may need additional capital to support our growth. While we expect to generate these funds from
operations, we may not be able to do so. Principal factors that could affect the availability of our internally generated funds include:



| |  |  | failure of sales from government, military and commercial markets to meet planned projections;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | government spending levels impacting the sale of our products;
| | - |  | --------------------------------------------------------------



| |  |  | our ability to control spending;
| | - |  | --------------------------------



| |  |  | introduction of new competing technologies;
| | - |  | -------------------------------------------



| |  |  | product mix and effect on margins; and
| | - |  | --------------------------------------



| |  |  | acceptance of our existing and future products in existing and new markets.
| | - |  | ---------------------------------------------------------------------------

##### Table of Contents

Should we require additional funds, general market conditions or the then-current market
price of our common stock may not support capital raising transactions and any such financing may require advance approval of our stockholders under the rules of the NASDAQ Stock Market. Our ability to obtain financing may be further constrained by
the current economic conditions. The recent credit crisis and other related trends affecting the capital markets have caused significant reductions in capital availability. Many lenders and institutional investors have ceased funding even the most
credit-worthy entities. In addition, we may be required to reduce costs, including the scaling back of research and development into new products, which could have a negative impact on our ability to compete and to innovate. If we raise additional
funds by selling additional shares of our capital stock or securities convertible into or exercisable for common stock (assuming we are able to obtain additional financing), the ownership interest of our stockholders will be diluted.

One customer accounted for 24% of our total revenues for fiscal year 2009. We expect to continue to be dependent on a limited number of customers.

One customer accounted for 24% of total revenues for the fiscal year 2009, and two customers accounted for 17% and 10% of
total revenues for the fiscal year 2008, respectively. Historically our revenues have been dependent upon a limited number of customers. We do not have long term agreements with these or other significant customers, and our customers have the right
to cease doing business with us at any time. No assurance can be given that these or other customers will continue to do business with us or that they will maintain their historical levels of business. If our relationship with any material customer
were to cease, then our revenues would decline and negatively impact our results of operations. Any such decline could result in us increasing our net losses and accumulated deficit and a need to raise additional capital to fund our operations. If
our expectations regarding future sales are inaccurate, we may be unable to reduce costs in a timely manner to adjust for sales shortfalls.

Disruption and fluctuations in financial and currency markets could have a negative effect on our business.

Financial markets in the United States, Europe and Asia have been experiencing extreme disruption over the past year, including, among other things, extreme volatility in security prices, severely diminished liquidity and credit
availability, rating downgrades of certain investments and declining valuations of others. Governments have taken unprecedented actions intended to address extreme market conditions that include severely restricted credit and declines in real estate
values. While currently these conditions have not impaired our ability to operate our business, there can be no assurance that there will not be a further deterioration in financial markets and confidence in major economies, which can then lead to
challenges in the operation of our business. These economic developments affect businesses such as ours in a number of ways. The current tightening of credit in financial markets adversely affects the ability of commercial customers to finance
purchases and operations and could result in a decrease in orders and spending for our products as well as create supplier disruptions. Economic developments could also reduce future government spending on our products. We are unable to predict the
likely duration and severity of the current disruption in financial markets and adverse economic conditions and the effects they will have on our business and financial condition.

We purchase a number of key components and subassemblies from foreign suppliers. Consequently, we are subject to the impact economic
conditions can have on such suppliers and subject to fluctuations in foreign currency exchange rates. Increases in our cost of purchasing these items could negatively impact our financial results if we are not able to pass these increased costs on
to our customers.

We must expand our customer base in order to grow our business.

To grow our business, we must fulfill orders from our existing customers, obtain additional orders from our existing customers, develop
relationships with new customers and obtain and fulfill orders from new customers. We cannot guarantee that we will be able to increase our customer base. Further, even if we do obtain new



10

##### Table of Contents

customers, we cannot guarantee that those customers will purchase from us enough quantities of our product or at product prices that will enable us to recover our costs in acquiring those
customers and fulfilling those orders. Whether we will be able to sell more of our products will depend on a number of factors, including:



| |  |  | our ability to manufacture reliable products that have the features that are required by our customers;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | our ability to expand relationships with existing customers and to develop relationships with new customers that will lead to additional orders for our
products;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our ability to develop and expand new markets for directed sound products; and
| | - |  | ------------------------------------------------------------------------------



| |  |  | our ability to develop international product distribution directly or through strategic partners.
| | - |  | -------------------------------------------------------------------------------------------------

The growth of our LRAD product revenues is dependent on continued acceptance of our products by government, military and developing force protection and
emergency response agencies. If these agencies do not purchase our LRAD products, our revenues will be adversely affected.

Although our LRAD products are designed for use by both government and commercial customers, the products have, to date, been predominantly sold for government use. While our government sales have been increasing, our products have not yet
been widely accepted in the large government and military market that includes many prospective customers. Furthermore, the force protection and emergency response market is itself an emerging market that is changing rapidly. If our LRAD products
are not widely accepted by the government, military and the developing force protection and emergency response markets, we may not be able to identify other markets, and we may fail to achieve our sales projections.

Perceptions that long range hailing devices are unsafe or may be used in an abusive manner may hurt sales of our LRAD products which could cause our
revenues to decline.

Potential customers for our LRAD products, including government, military and force protection and
emergency response agencies, may be influenced by claims or perceptions that long range hailing devices are unsafe or may be used in an abusive manner. These claims or perceptions, while unsubstantiated, could reduce our product sales.

A significant portion of our revenue is derived from a few core product categories.

We are dependent on a small number of core product categories to generate a significant proportion of our revenues. No assurance can be given
that these or other products will continue to have consumer acceptance or that they will maintain their historical levels of sales. The loss of one or more of these products could have a material adverse effect on our business, results of
operations, financial condition and liquidity.

We are continually introducing new or improved products and technologies. If commercially
successful products are not produced in a timely manner, we may be unprofitable or forced to cease operations.

Our HSS and
SoundSaber technologies have had only limited market acceptance and are still being improved. Commercially viable sound technology systems may not be successfully and timely produced by us due to the inherent risks of technology development, new
product introduction, limitations on financing, manufacturing problems, competition, obsolescence, loss of key technical personnel and other factors. Revenues from these products have been limited to date and we cannot guarantee significant revenues
in the future. The development and introduction of our HSS product took longer than anticipated by management and the introduction of future products, if any, could also be subject to delays. Customers may not accept our current products and may
elect to purchase products from competitors. We experienced quality control problems with some of our initial commercial HSS units, and we may not be able to resolve similar problems in a timely and cost effective manner. Products employing our
sound technology may not achieve market acceptance. Our various sound projects are high risk in nature, and unanticipated technical obstacles can arise at any time and



11

##### Table of Contents

result in lengthy and costly delays or result in a determination that further exploitation is unfeasible. If we do not successfully exploit our technology, our financial condition, results of
operations and business prospects would be adversely affected.

We may incur significant and unpredictable warranty costs.

Our products are substantially different from proven, mass produced sound transducer designs and are often employed in harsh environments.
We may incur substantial and unpredictable warranty costs from post-production product or component failures. We generally warrant our products to be free from defects in materials and workmanship for a period up to one year from the date of
purchase. At September 30, 2009, we had a warranty reserve of $277,717. In prior years, we recorded substantial warranty reserves for early versions of our HSS products and have limited history to predict future warranty costs. Future warranty
costs could further adversely affect our financial position, results of operations and business prospects.

We could incur additional
charges for excess and obsolete inventory.

Due to rapidly changing technology, and uneven customer demand, product cycles
tend to be short and the value of our inventory may be adversely affected by changes in technology that affect our ability to sell the products in our inventory. If we do not effectively forecast and manage our inventory, we may need to write off
inventory as excess or obsolete, which in turn can adversely affect cost of sales and gross profit.

We have previously
experienced, and may in the future experience, reductions in sales of older generation products as customers delay or defer purchases in anticipation of new product introductions. We currently have established reserves for slow moving or obsolete
inventory of approximately $1.7 million. The reserves we have established for potential losses due to obsolete inventory may, however, prove to be inadequate and may give rise to additional charges for obsolete or excess inventory.

We do not have the ability to accurately predict future operating results. Our quarterly and annual revenues are likely to fluctuate significantly due to
many factors, any of which could result in our failure to achieve our revenue expectations.

We expect our proprietary
sound reproduction products and technologies will be the source of substantially all of our future revenues. Revenues from these products and technologies are expected to vary significantly due to a number of factors, many of which are beyond our
control. Any one or more of the factors listed below or other factors could cause us to fail to achieve our revenue expectations. These factors include:



| |  |  | our ability to develop and supply sound reproduction components to customers, distributors or OEMs or to license our technologies;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------



| |  |  | market acceptance of and changes in demand for our products or products of our customers;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | gains or losses of significant customers, distributors or strategic relationships;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | unpredictable volume and timing of customer orders;
| | - |  | ---------------------------------------------------



| |  |  | the availability, pricing and timeliness of delivery of components for our products and OEM products;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | fluctuations in the availability of manufacturing capacity or manufacturing yields and related manufacturing costs;
| | - |  | -------------------------------------------------------------------------------------------------------------------



| |  |  | the timing of new technological advances, product announcements or introductions by us, by OEMs or licensees and by our competitors;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | product obsolescence and the management of product transitions and inventory;
| | - |  | -----------------------------------------------------------------------------



| |  |  | unpredictable warranty costs associated with new product models;
| | - |  | ----------------------------------------------------------------

##### Table of Contents

| |  |  | production delays by customers, distributors, OEMs or by us or our suppliers;
| | - |  | -----------------------------------------------------------------------------



| |  |  | the conditions of other industries, such as military and commercial industries, into which our technologies may be licensed;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | general consumer electronics industry conditions, including changes in demand and associated effects on inventory and inventory practices;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | general economic conditions that could affect the timing of customer orders and capital spending and result in order cancellations or rescheduling; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | general political conditions in this country and in various other parts of the world that could affect spending for the products that we offer.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------

Some or all of these factors could adversely affect demand for our products or technologies, and therefore
adversely affect our future operating results.

Most of our operating expenses are relatively fixed in the short term. We may
be unable to rapidly adjust spending to compensate for any unexpected sales or license revenue shortfalls, which could harm our quarterly operating results. We do not have the ability to predict future operating results with any certainty.

Many potential competitors who have greater resources and experience than we do may develop products and technologies that make ours
obsolete.

Technological competition from other and longer established electronic and loudspeaker manufacturers are
expected to increase. Most of the companies with which we expect 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 our competitors may have developed or may succeed in developing technologies and products that are more effective than any of ours, rendering our technology
and products obsolete or noncompetitive.

Our competitive position will be seriously damaged if we cannot protect intellectual property
rights in our technology.

We rely on a combination of contracts and trademark, patent and trade secret laws to establish
and protect our proprietary rights in our technology. However, we may not be able to prevent misappropriation of our intellectual property, our competitors may be able to independently develop competing technologies, or the agreements we enter into
may not be enforceable.

Our success, in part, depends on our ability to obtain and enforce intellectual property protection
for our technology. There is no guarantee any patent will issue on any patent application that we have filed or may file. Claims allowed from existing or pending patents may not be of sufficient scope or strength to protect the economic value of our
technologies. Further, any patent that we may obtain will expire, and it is possible that it may be challenged, invalidated or circumvented. If we do not secure and maintain patent protection for our technology and products, our competitive position
will be significantly harmed. A competitor may independently develop or patent technologies that are substantially equivalent to or superior to our technology. If this happens, any patent that we may obtain may not provide protection and our
competitive position could be significantly harmed.

As we expand our product line or develop new uses for our products, these
products or uses may be outside the protection provided by our current patent applications and other intellectual property rights. In addition, if we develop new products or enhancements to existing products we cannot assure you that we will be able
to obtain patents to protect them. Even if we do receive patents for our existing or new products, these patents may not provide meaningful protection. In some countries outside of the United States where our products can be sold or



13



---

##### Table of Contents

licensed, patent protection is not available. Moreover, some countries that do allow registration of patents do not provide meaningful redress for violations of patents. As a result, protecting
intellectual property in these countries is difficult and our competitors may successfully sell products in those countries that have functions and features that infringe on our intellectual property.

We may initiate claims or litigation against third parties in the future for infringement of our proprietary rights or to determine the
scope and validity of our proprietary rights or the proprietary rights of our competitors. These claims could result in costly litigation and divert the efforts of our technical and management personnel. As a result, our operating results could
suffer and our financial condition could be harmed.

We may be faced with legal challenges related to our products, including that our
products infringe third parties intellectual property rights of others. These challenges could cause us to incur significant litigation or licensing expenses or could prohibit us from producing or marketing some or all of our products
entirely.

Other companies and our competitors may currently own or obtain patents or other proprietary rights that might
prevent, limit or interfere with our ability to make, use or sell our products. Although we do not believe that our products infringe the proprietary rights of any third parties, there can be no assurance that infringement or other legal claims will
not be asserted against us or that any such claims will not materially adversely affect our business, financial condition, or results of operations. The electronics industry is characterized by vigorous protection and pursuit of intellectual
property rights or positions. Regardless of their validity or success, such claims may result in protracted and costly litigation, divert managements time and attention, cause product shipment delays or require us to enter into royalty or
licensing agreements, which may not be available on terms acceptable to us, or at all. In the event of a successful claim of infringement against us and our failure or inability to license the infringed technology, our business and operating results
could be adversely affected. An adverse result from intellectual property litigation could force us to do one or more of the following:



| |  |  | cease selling, incorporating or using products or services that incorporate the challenged intellectual property;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | obtain a license from the holder of the infringed intellectual property right, which license may not be available on reasonable terms, if at all; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | redesign products or services that incorporate the disputed technology.
| | - |  | -----------------------------------------------------------------------

If we are forced to take any of the foregoing actions, we could face substantial costs and shipment delays and our business could be
seriously harmed. Although we carry general liability insurance, our insurance may not cover potential claims of this type or be adequate to indemnify us for all liability that may be imposed.

In addition, it is possible that our customers or end users may seek indemnity from us in the event that our products are found or alleged
to infringe the intellectual property rights of others. Any such claim for indemnity could result in substantial expenses to us that could harm our operating results.

Our HSS technology is subject to regulation by the Food and Drug Administration, which could lead to unanticipated expense or litigation.

Our HSS sound technology emits ultrasonic vibrations, and as such is regulated by the Food and Drug Administration. In the event of certain
unanticipated defects in an HSS product, a customer or we may be required to comply with FDA requirements (1) to provide written notification of the defect to: the FDA; dealers or distributors to whom the product was delivered; and purchasers
of the product (and any reasonably ascertainable subsequent transferees), and (2) to repair, replace, or refund to the purchaser the cost of the product. This could lead to unanticipated expense, and possible product liability litigation
against a customer or us. Any regulatory impediment to full commercialization of our HSS technology, or any of our other technologies, could adversely affect our results of operations.

We may face personal injury and other liability claims that harm our reputation and adversely affect our
sales and financial condition.

Some of our products are capable of sufficient acoustic output to cause damage to human
hearing or human health if used improperly, such as when the products are used at close ranges or for long periods of exposure. A person injured in connection with the use of our products may bring legal action against us to recover damages on the
basis of theories including personal injury, negligent design, dangerous product or inadequate warning. We may also be subject to lawsuits involving allegations of misuse of our products. Our product liability insurance coverage may be insufficient
to pay all such claims. Product liability insurance may also become too costly for us or may become unavailable for us in the future. We may not have sufficient resources to satisfy any product liability claims not covered by insurance which would
materially and adversely affect our financial position. Significant litigation could also result in negative publicity and a diversion of managements attention and resources.

Our international operations could be harmed by factors including political instability, natural disasters, fluctuations in currency exchange rates and changes in regulations that govern international
transactions.

We sell our products worldwide. The risks inherent in international trade may reduce our international sales
and harm our business and the businesses of our customers and our suppliers. These risks include:



| |  |  | changes in tariff regulations;
| | - |  | ------------------------------



| |  |  | political instability, war, terrorism and other political risks;
| | - |  | ----------------------------------------------------------------



| |  |  | foreign currency exchange rate fluctuations;
| | - |  | --------------------------------------------



| |  |  | establishing and maintaining relationships with local distributors and dealers;
| | - |  | -------------------------------------------------------------------------------



| |  |  | lengthy shipping times and accounts receivable payment cycles;
| | - |  | --------------------------------------------------------------



| |  |  | import and export control and licensing requirements;
| | - |  | -----------------------------------------------------



| |  |  | compliance with a variety of U.S. laws, including the Foreign Corrupt Practices Act, by us or key subcontractors;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | compliance with a variety of foreign laws and regulations, including unexpected changes in taxation and regulatory requirements;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | greater difficulty in safeguarding intellectual property than in the U.S.; and
| | - |  | ------------------------------------------------------------------------------



| |  |  | difficulty in staffing and managing geographically diverse operations.
| | - |  | ----------------------------------------------------------------------

These and other risks may preclude or curtail international sales or increase the relative price of our products compared to those
manufactured in other countries, reducing the demand for our products. Failure to comply with U.S. and foreign governmental laws and regulations applicable to international business such as the Foreign Corrupt Practices Act or U.S. export control
regulations could have an adverse impact on our business with the U.S. and foreign governments.

Current environmental laws, or laws
enacted in the future, may harm our business.

Our operations are subject to environmental regulation in areas in which we
conduct business. Our product design and procurement operations must comply with new and future requirements relating to the materials composition of our products, including restrictions on lead, cadmium and other substances. We do not expect that
the impact of these environmental laws and other similar legislation adopted in the U.S. and other countries will have a substantial unfavorable impact on our business. However the costs and timing of costs under environmental laws are difficult to
predict.

Errors or defects contained in our products, failure to comply with applicable safety standards or a
product recall could result in delayed shipments or rejection of our products, damage to our reputation and expose us to regulatory or other legal action.

Any defects or errors in the operation of our products may result in delays in their introduction. In addition, errors or defects may be uncovered after commercial shipments have begun, which could result
in the rejection of our products by our customers, damage to our reputation, lost sales, diverted development resources and increased customer service and support costs and warranty claims, any of which could harm our business. Third parties could
sustain injuries from our products, and we may be subject to claims or lawsuits resulting from such injuries. There is a risk that these claims or liabilities may exceed, or fall outside the scope of, our insurance coverage. We may also be unable to
obtain adequate liability insurance in the future. Because we are a small company, a product recall would be particularly harmful to us because we have limited financial and administrative resources to effectively manage a product recall and it
would detract managements attention from implementing our core business strategies. A significant product defect or product recall could materially and adversely affect our brand image, causing a decline in our sales, and could reduce or
deplete our financial resources.

We rely on outside manufacturers and suppliers to provide a large number of components and sub-assemblies
incorporated in our products.

Our products have a large number of components and sub-assemblies produced by outside
suppliers. In addition, for certain of these items, we qualify only a single source, which can magnify the risk of shortages and decrease our ability to negotiate with our suppliers on the basis of price. In particular, we depend on our HSS
piezo-film supplier to provide materials used in our proprietary HSS emitters and we rely on one supplier for a key component for our LRAD products. If shortages occur, or if we experience quality problems with suppliers, then our production
schedules could be significantly delayed or costs significantly increased, which would have a material adverse effect on our business, liquidity, results of operation and financial position.

Although we assemble our products internally, we have some sub-assemblers and components produced by third-party manufacturers. We may be
required to outsource manufacturing if sales of our products increase significantly. We have historically used a single third-party contract manufacturer to manufacture for certain sub-assemblies, and we expect to continue to use a single
manufacturer in the future until product volume grows substantially. We may be unable to obtain acceptable manufacturing sources on a timely basis. In addition, from time to time we may change manufacturers and any new manufacturer engaged by us may
not perform as expected. An extended interruption in the supply of our products could result in a substantial loss of sales. Furthermore, any actual or perceived degradation of product quality as a result of our reliance on third-party manufacturers
may have an adverse effect on sales or result in increased warranty costs, product returns and buybacks. Failure to maintain quality manufacturing could reduce future revenues, adversely affecting financial condition and results of operations.

We derive revenue from government contracts and subcontracts, which are often non-standard, may involve competitive bidding, may be
subject to cancellation with or without penalty and may produce volatility in earnings and revenue.

Our sales to
government customers have involved and are expected in the future to involve providing products and services under contracts or subcontracts with U.S. federal, state, local and foreign government agencies. Obtaining contracts and subcontracts from
government agencies is challenging, and contracts often include provisions that are not standard in private commercial transactions. For example, government contracts may:



| |  |  | include provisions that allow the government agency to terminate the contract without penalty under some circumstances;
| | - |  | -----------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | be subject to purchasing decisions of agencies that are subject to political influence;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | contain onerous procurement procedures; and
| | - |  | -------------------------------------------



| |  |  | be subject to cancellation if government funding becomes unavailable.
| | - |  | ---------------------------------------------------------------------

Securing government contracts can be a protracted process involving competitive bidding. In many cases, unsuccessful bidders may challenge
contract awards, which can lead to increased costs, delays and possible loss of the contract for the winning bidder.

We have current
government contracts and our future growth is dependent, in large part, on continued sales to U.S. and international governments and businesses who sell to governments.

In fiscal 2009, direct and indirect sales to the U.S. government accounted for approximately 45% of our total net sales. Changes in defense
spending could have an adverse effect on our current and future revenues. Sales of our product to U.S. government agencies and organizations is subject to the overall U.S. government budget and congressional appropriation decisions and processes
which are driven by numerous factors, including geo-political events and macroeconomic conditions, and are beyond our control. The recent election and changes in political leadership could affect future U.S. Department of Defenses military
initiatives and homeland security spending. We cant be assured that the militarys interest in communication devices to minimize unnecessary force will continue or will provide future growth opportunities for our business.

Our success is dependent on the performance of our executive team, and the cooperation, performance and retention of our executive officers and key
employees.

Over the past few years, we have experienced significant changes in our senior management. Our business and
operations are substantially dependent on the performance of our current executive team including our President and Chief Executive Officer and our Chief Financial Officer. We do not maintain key person life insurance on any of our
executive officers. The loss of one or several key employees could seriously harm our business.

We are also dependent on our
ability to retain and motivate high quality personnel, especially sales and marketing executives and skilled technical personnel. Competition for such personnel is intense, and we may not be able to attract, assimilate or retain other highly
qualified managerial, sales and technical personnel in the future. The inability to attract and retain the necessary managerial, sales and technical personnel could cause our business, operating results or financial condition to suffer.

We may not address successfully the problems encountered in connection with any potential future acquisitions.

We expect to continue to consider opportunities to acquire or make investments in other technologies, products and businesses that could
enhance our capabilities, complement our current products or expand the breadth of our markets or customer base. We have little experience in acquiring other businesses and technologies. Potential and completed acquisitions and strategic investments
involve numerous risks and if we fail to properly evaluate and execute acquisitions and strategic investments, our management team may be distracted from our day-to-day operations, our business may be disrupted and our operating results may suffer.
In addition, if we finance acquisitions by issuing equity or convertible debt securities, our stockholders would be diluted.

Our
disclosure controls and procedures may not prevent or detect all acts of fraud.

Our disclosure controls and procedures are
designed to reasonably assure that information required to be disclosed in reports filed or submitted under the Securities Exchange Act is accumulated and communicated to



17

##### Table of Contents

management and is recorded, processed, summarized and reported within the time periods specified in the SECs rules and forms. Our management expects that our disclosure controls and
procedures and internal controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control
systems, they cannot provide absolute assurance that all control issues and instances of fraud, if any, within our company have been prevented or detected. These inherent limitations include the realities that judgments in decision-making can be
faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by an unauthorized override of the controls. The
design of any systems of controls also is based in part upon certain assumptions about the likelihood of future events, and we cannot assure that any design will succeed in achieving its stated goals under all potential future conditions.
Accordingly, because of the inherent limitations in a cost effective control system, misstatements due to error or fraud may occur and not be detected.

Failure to maintain an effective system of internal control over financial reporting could harm stockholder and business confidence in our financial reporting, our ability to obtain financing and other
aspects of our business.

Maintaining an effective system of internal control over financial reporting is necessary for us
to provide reliable financial reports. Section 404 of the Sarbanes-Oxley Act of 2002 and the related rules and regulations promulgated by the SEC require us to include in our Form 10-K a report by management regarding the effectiveness of
our internal control over financial reporting. The report includes, among other things, an assessment of the effectiveness of our internal control over financial reporting as of the end of the respective fiscal year, including a statement as to
whether or not our internal control over financial reporting is effective. This assessment must include disclosure of any material weaknesses in our internal control over financial reporting identified by management. While our management has
concluded that we did not have any material weaknesses as of September 30, 2009, it is possible that material weaknesses will be identified in the future. In addition, components of our internal control over financial reporting may require
improvement from time to time. If management is unable to assert that our internal control over financial reporting is effective in any future period, investors may lose confidence in the accuracy and completeness of our financial reports, which
could have an adverse effect on its stock price.

Evolving regulation of corporate governance and public disclosure may result in
additional expenses and continuing uncertainty.

During fiscal 2005, 2006 and 2007, we incurred substantial costs in
complying with Section 404 of the Sarbanes-Oxley Act of 2002 relating to the evaluation of our internal control over financial reporting and having our independent auditor attest to that evaluation. Compliance with these requirements, and other
similar corporate regulations, has been and is expected to continue to be expensive and time consuming.

Changing laws,
regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new SEC regulations and NASDAQ Stock Market rules are creating uncertainty for public companies. We continually evaluate and
monitor developments with respect to new and proposed rules and cannot predict or estimate the amount of the additional costs we may incur or the timing of such costs. These new or changed laws, regulations and standards are subject to varying
interpretations, in many cases due to their lack of specificity, and as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty
regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.

We
are committed to maintaining high standards of corporate governance and public disclosure. If our efforts to comply with new or changed laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to
ambiguities related to practice, regulatory authorities may initiate legal proceedings against us and we may be harmed.

Our common stock may be delisted from the Nasdaq Stock Market.

Nasdaqs continued listing standards for our common stock require, among other things, that (i) we maintain a closing bid price for
our common stock of at least $1.00, and (ii) we maintain: (A) stockholders equity of $2.5 million; (B) market value of listed securities of $35 million; or (C) net income from continuing operations of $500,000 in the most
recently completed fiscal year or in two of the last three most recently completed fiscal years. In October 2008, we were notified by Nasdaq that we failed to meet the listing standards by failing to maintain a bid price of $1.00 but we received
notice from Nasdaq on April 22, 2009 that we became compliant by meeting the bid price requirement. Future failures to satisfy any continued listing requirements could lead to the receipt of a deficiency notice from Nasdaq and ultimately to a
delisting from trading of our common stock. If our common stock were delisted from Nasdaq, among other things, this could result in a number of negative implications, including reduced liquidity in our common stock as a result of the loss of market
efficiencies associated with Nasdaq and the loss of federal preemption of state securities laws as well as the potential loss of confidence by suppliers, customers and employees, the loss of analyst coverage and institutional investor interest,
fewer business development opportunities, greater difficulty in obtaining financing and breaches of certain contractual obligations.

Sales
of common stock issuable on the exercise of outstanding options and warrants, may depress the price of our common stock.

As of September 30, 2009, we had outstanding options granted to our employees, directors and consultants to purchase 4,068,409 shares of our common stock, and had outstanding warrants issued to investors and others to purchase
2,098,204 shares of our common stock. At September 30, 2009, the exercise prices for the options and warrants ranged from $0.46 to $9.48 per share. The issuance of shares of common stock issuable upon the exercise of outstanding options or
warrants could cause substantial dilution to holders of common stock, and the sale of those shares in the market could cause the market price of our common stock to decline. The potential dilution from these shares could negatively affect the terms
on which we could obtain equity financing.

We may issue preferred stock in the future, and the terms of the preferred stock may reduce the
value of your common stock.

We are authorized to issue up to 5,000,000 shares of preferred stock in one or more series.
Our board of directors may determine the terms of future preferred stock offerings without further action by our stockholders. If we issue additional preferred stock, it could affect the rights or reduce the value of our common stock. In particular,
specific rights granted to future holders of preferred stock could be used to restrict our ability to merge with or sell our assets to a third party. These terms may include voting rights, preferences as to dividends and liquidation, conversion and
redemption rights, and sinking fund provisions.

Our stock price is volatile and may continue to be volatile in the future.

The market price of our common stock has fluctuated significantly to date. In the future, the market price of our common stock could be
subject to significant fluctuations due to general market conditions and in response to quarter-to-quarter variations in:



| |  |  | our anticipated or actual operating results;
| | - |  | --------------------------------------------



| |  |  | developments concerning our sound reproduction technologies;

The stock market in recent years has experienced extreme price and volume fluctuations that
have affected the market price of many technology companies, and that have often been unrelated or disproportionate to the operating performance of companies.

The implementation of authoritative accounting guidance issued by the Financial Accounting Standards Board (FASB) Emerging Issues Task Force (EITF), which is effective for our consolidated financial
statements for the fiscal year beginning October 1, 2009, could have a substantial unfavorable impact on our financial statements.

We have determined that based on provisions of accounting guidance issued by the EITF, as codified in FASB Accounting Standards Codification (ASC) 815-40 (formerly EITF 07-5), warrants granted in 2006
contain a strike price adjustment feature that causes these warrants to change the current classification of these instruments from equity to a current liability as of October 1, 2009. These warrants will be revalued based on assumptions at the
end of each reporting period, including stock price, volatility, interest rates and remaining term. An increase in the companys stock price or changes in the stock price volatility or other assumptions could result in an increase in the
warrant liability and in a significant non-cash charge to our results of operations.

estimation, record adequate reserves in our financial statements for pending litigation. Litigation is expensive and is subject to inherent uncertainties, and an adverse result in any such matters could adversely impact our operating results or
financial condition. Additionally, any litigation to which we may become subject could also require significant involvement of our senior management and may divert managements attention from our business and operations.

The discussion and analysis set forth below in this section should be read in conjunction with the information presented in other sections of
this Annual Report on Form 10-K, including Item 1. Business, Item 1A. Risk Factors, and Item 8. Financial Statements and Supplementary Data. This discussion contains forward-looking statements which are based on
our current expectations and industry experience, as well as our perception of historical trends, current market conditions, current economic data, expected future developments and other factors that we believe are appropriate under the
circumstances. These statements involve risks and uncertainties that could cause actual results to differ materially from those suggested in the forward-looking statements.

Overview

We are a pioneer of highly intelligible, high clarity directed
sound technologies and products. We aggressively seek to create markets for our products, and we are increasing our focus on and investment in worldwide sales and marketing activities while we continue to innovate.

In fiscal 2008, we completed the development and introduced a new generation of LRAD products called the LRAD-X. Our new LRAD-X products use
directionality and focused acoustic output to clearly transmit critical information, instructions and warnings 1,000 meters and beyond. The LRAD-X product line features improved voice intelligibility and is available in a number of packages that
meet the militarys stringent environmental requirements in a number of packages and form factors. Through the use of powerful voice commands and deterrent tones, large safety zones can be created while determining the intent and influencing
the behavior of an intruder. Our LRAD-X product line provides a complete range of systems from single man portable to permanently installed, remotely operated infrastructure production. Our LRAD products have been competitively selected over other
commercially available systems by the U.S. military. Our new product line includes the following:



| |  |  | LRAD 1000Xselected by the U.S. Navy as its AHD for Block 0 of the Shipboard Protection Systemcan be manually operated to provide long
distance hailing and warning with highly intelligible communication.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | LRAD 500Xselected by the U.S. Navy and U.S. Army as their AHD for small vessels and vehiclesis lightweight and can be easily transported to
provide security personnel long-range communications and a highly effective hailing and warning capability where needed.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | LRAD 300X The newest addition to our product line, introduced in fiscal 2009is a lightweight mid-range AHD developed for small vessels and
manned and unmanned vehicles and aircraft.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | LRAD 100X is a self-contained, battery powered, portable system designed for use in a variety of mass notification, law enforcement and commercial
security applications. It is ideally suited for short-range perimeter security and communications.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | LRAD-RX is our prescription for remotely controlled security. It enables system operators to detect and communicate with an intruder over long
distances. LRAD-RX features an LRAD 1000X emitter head, integrated camera, high-intensity searchlight and a newly developed, robust, and IP-addressable full pan and tilt drive system for precise aiming and tracking. LRAD-RX can also be integrated
with radar to provide automated intruder alerts. Because of its automated capabilities, LRAD-RX reduces manpower and false alarms while providing an intelligent, cost-effective security solution.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We incurred $2,106,959 of research and development expense during fiscal 2009, a decrease of 37% from the prior year. Research and
development expenses were reduced in fiscal 2009, following the launch of our enhanced LRAD-X product line during fiscal 2008. We focused during fiscal 2009 on the development of the LRAD 300X product, as well as cost reductions and customized
applications of existing products. We believe these products provide increased opportunities in government and commercial markets and allow us to continue as the leader in this market. We intend to continue to innovate during fiscal 2010 with
consistent levels of expenditures for research and development.

##### Table of Contents

We incurred net losses of $1,042,753 and $6,360,276 in the fiscal years ended
September 30, 2009 and 2008, respectively. We generated $2,578,630 of cash from operating activities during fiscal 2009 compared to using $3,409,932 for operating activities in the prior year. We generated positive cash flow from
operations for fiscal 2009 despite our net loss in large part because of the non-cash expenses recorded for share-based compensation and accrued bonuses of $1,562,633 and $1,085,559, respectively, that reduced earnings, but not cash flow. Future
cash from operating activities are also expected to be impacted by other factors including changes in receivables, payables and accruals. We have substantial research and development and selling, marketing and general administrative expenses, and
our margins from the sale of our products have not yet been sufficient to offset these costs. We believe we have adequate financial resources to sustain operations for the next twelve months.

Business Outlook

We
recorded revenues of $15,824,838 for the fiscal year ended September 30, 2009, a 41% increase over the prior years revenues of $11,189,942. Gross profit improved from $4,410,729 (39% of revenue) in the year ended September 30, 2008
to $7,450,756 (47% of revenue) in the year ended September 30, 2009. In fiscal year 2009, our gross profit margin was favorably impacted by increased unit shipments and reduced product cost on our LRAD-X product line.

In fiscal 2009, our operating expenses of $8,472,605 represented a decrease of $2,384,497 compared to the prior year. Fiscal 2009 operating
expenses included $1,485,752 of non-cash share-based compensation costs, a decrease of $749,609 from the prior year. In addition, we decreased spending in research and development by $764,869 following an increase in fiscal 2008 for the development
and launch of our LRAD-X product line, reduced staffing by $819,241, decreased legal, auditing and accounting costs by $415,504, reduced patent impairments by $281,145 and reduced selling expenses and travel by $260,339. These decreases were
partially offset by $843,510 for bonus expense based on meeting company targets for the year and increased commission to outside sales representatives of $337,291.

Our $1,021,849 operating loss for our fiscal year ended September 30, 2009 was a $5,424,524 improvement from the $6,446,373 in the prior year, primarily due to increased revenue, improved product
margins and reduced operating expenses.

In fiscal year 2010, we anticipate our revenues will continue to grow, primarily due
to the increased acceptance of our LRAD, HSS and SoundSaber products, and a stronger sales channel. We believe we have a solid technology and product foundation for business growth. We are experiencing positive response to our new LRAD-X
product line, and we have additional technologies and products planned for fiscal 2010. We have strong market opportunities within the government and military sector, as well as increased commercial applications as a result of continued global
threats to governments, commerce, law enforcement and wildlife preservation and control. Our selling network has expanded to include a number of key integrators and sales representatives within the United States and in a number of worldwide
locations. However, we may face challenges in fiscal 2010 from extreme international market conditions that are severely restricting credit and disrupting major economies. A further and continued deterioration in financial markets and confidence in
major economies could disrupt the operation of our business.

Critical Accounting Policies and Estimates

We have identified the policies below as critical to our business operations and to understanding our results of operations. Our accounting
policies are more fully described in our financial statements and related notes located in Item 8. Financial Statements and Supplementary Data. The impact and any associated risks related to these policies on our business operations are
discussed in Item 1A. Risk Factors and throughout Managements Discussion and Analysis of Financial Condition and Results of Operations when such policies affect our reported and expected financial results.

The methods, estimates and judgments we use in applying our accounting policies, in
conformity with generally accepted accounting principles in the United States, have a significant impact on the results we report in our financial statements. We base our estimates on historical experience and on various other assumptions that we
believe to be reasonable under the circumstances. These estimates affect the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions.

Revenue Recognition.We currently derive our revenue primarily from two sources: (i) component and product sale revenues and
associated engineering and installation, which we refer to collectively as product sales and (ii) contract and license fee revenues. Product sales revenues are recognized in the periods that products are shipped to customers (FOB shipping
point) or when product is received by the customer (FOB destination), when the fee is fixed and determinable, when collection of resulting receivables is probable and there are no remaining obligations on our part. Revenues from engineering
contracts are recognized based on milestones or completion of the contracted services. Revenues from up-front license and other fees and annual license fees are evaluated for multiple elements but are generally recognized ratably over the specified
term of the particular license or agreement. Revenues from ongoing per unit license fees are earned based on units shipped by the licensee incorporating our patented proprietary technologies. Revenues are recognized in the period when the ultimate
customer accepts the product and collectability is reasonably assured.

Share-Based Compensation. We account for
share-based compensation in accordance with the provisions of ASC 718, CompensationStock Compensation (formerly SFAS No. 123(R)), using the modified prospective method which requires the measurement and recognition of
compensation expense for all share-based payment awards made to employees and directors based on estimated fair values. ASC 718 requires the use of subjective assumptions, including expected stock price volatility and the estimated term of each
award. We estimate the fair value of stock options granted using the Black-Scholes option-pricing model, which is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. This
model also utilizes the fair value of our common stock and requires that, at the date of grant, we use the expected term of the share-based award, the expected volatility of the price of our common stock over the expected term, the risk free
interest rate and the expected dividend yield of our common stock to determine the estimated fair value. We determine the amount of share-based compensation expense based on awards that we ultimately expect to vest, reduced for estimated
forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Share-based compensation expense includes awards granted prior to, but
not yet vested as of September 30, 2005, based on the grant date fair value estimated in accordance with the pro forma provisions of SFAS No. 123 and compensation expense for awards granted subsequent to September 30, 2005 based on
the grant date fair value estimated in accordance with the provisions of ASC 718.

We account for equity instruments issued in
exchange for the receipt of goods or services from non-employees in accordance with the consensus of ASC 505-50, Equity-Based Payments to Non-Employees (formerly EITF No. 96-18). Costs are measured at the fair market value of the
consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. The value of equity instruments issued for consideration other than employee services is determined on the earlier of the date on which
there first exists a firm commitment for performance by the provider of goods or services or on the date performance is complete.

Allowance for doubtful accounts. Our products are sold to customers in many different markets and geographic locations. We estimate our bad debt reserve on a case-by-case basis due to a limited number of customers. We base these
estimates on many factors including customer credit worthiness, past transaction history with the customer, current economic industry trends and changes in customer payment terms. Our judgments and estimates regarding collectability of accounts
receivable have an impact on our financial statements.

Valuation of Inventory.Our inventory is comprised of raw materials, assemblies and
finished products. We must periodically make judgments and estimates regarding the future utility and carrying value of our inventory. The carrying value of our inventory is periodically reviewed and impairments, if any, are recognized when the
expected future benefit from our inventory is less than its carrying value. For the fiscal year ended September 30, 2009, we reviewed the carrying value of our inventory and increased the inventory reserve by $147,701 primarily to reserve
for excess HSS components and certain other slow moving components associated with our older generation of products and changes in demand.

Valuation of Intangible Assets. Intangible assets consist of patents that are amortized over their estimated useful lives. We must make judgments and estimates regarding the future utility and
carrying value of intangible assets. The carrying values of such assets are periodically reviewed and impairments, if any, are recognized when the expected future benefit to be derived from an individual intangible asset is less than its carrying
value. In fiscal year ended September 30, 2009, we reviewed the carrying value of our intangible assets and reduced it by $91,470 due to certain assets that are no longer consistent with our business strategy and whose expected future
value has decreased.

Accrued Expenses. We establish a warranty reserve based on anticipated warranty claims at the
time product revenue is recognized. This reserve requires us to make estimates regarding the amount and costs of warranty repairs we expect to make over a period of time. Factors affecting warranty reserve levels include the number of units sold,
anticipated cost of warranty repairs, and anticipated rates of warranty claims. The warranty reserve at September 30, 2009 was $277,717, compared to $235,174 as of September 30, 2008. We evaluate the adequacy of this reserve each reporting
period.

We use the recognition criteria of ASC 450-20, Loss Contingencies to estimate the amount of bonuses when
it becomes probable a bonus liability will be incurred and we recognize expense ratably over the service period. As no target-based bonuses were earned in any prior years that our bonus plan has been in place, and there was significant uncertainty
that the targets for fiscal 2009 would be achieved, we accrued no bonus expense until the fourth quarter when $1,085,559 was recorded for fiscal 2009 bonuses and related taxes.

Deferred Tax Asset.We have provided a full valuation reserve related to our substantial deferred tax assets. In the future, if
sufficient evidence of our ability to generate sufficient future taxable income in certain tax jurisdictions becomes apparent, we may be required to reduce our valuation allowances, resulting in income tax benefits in our consolidated statement of
operations. We evaluate quarterly the realizability of the deferred tax assets and assess the need for a valuation allowance. Utilizing the net operating loss carry forwards in future years could be substantially limited due to restrictions imposed
under federal and state laws upon a change in ownership or control. Included in the net operating loss carryforward are deductions from stock options that if recognized will be recorded as a credit to additional paid-in capital rather than through
operations.

Recent Accounting Pronouncements

A number of new pronouncements have been issued for future implementation as discussed in the notes to our consolidated financial statements located in Item 8. Financial Statements and Supplementary
Data. See Note 1 of our consolidated financial statements for further discussion.

Segment Information

We are engaged in the design, development and commercialization of directed sound technologies and products. We present our business as one
reportable segment due to the similarity in nature of products marketed, financial performance measures (revenue growth and gross margin), methods of distribution (direct and indirect) and customer markets (each product is sold by the same personnel
to government and commercial customers, domestically and internationally). Our chief operating decision making officer reviews financial information on sound products on a consolidated basis.

Revenues

Revenues increased $4,634,896, or 41%, in the fiscal year ended September 30, 2009 to $15,824,838 compared to $11,189,942 for the fiscal year ended September 30, 2008. Fiscal year 2009 revenues
included $15,488,667 of product sales and $336,171 of contract, license and other revenue. Fiscal year 2008 revenues included $10,647,935 of product sales and $542,007 of contract, license and other revenue. The increase in fiscal year 2009 revenues
reflected an increase in LRAD revenue from $9,152,962 in fiscal 2008 to $14,328,389 in fiscal 2009, due primarily to the launch of the new LRAD-X products and expanded sales distribution. HSS revenues decreased from $713,294 in fiscal year 2008 to
$586,693 in 2009, as demand from certain key customers in the digital signage and in-store broadcasting markets declined.

For
the year ended September 30, 2008, we recognized $162,500 in contract revenue representing ratable earned revenue under a three year license agreement. We did not record any similar contract revenue in the current year as the contract expired
in September 2008. At September 30, 2009, we had aggregate deferred license revenue of $273,954 representing amounts collected from another license agreement in advance of recognized earnings. This revenue component is subject to significant
variability based on the timing, amount and recognition of new arrangements, if any.

Gross Profit

Gross profit for the year ended September 30, 2009 was $7,450,756, or 47% of total revenues, compared to $4,410,729, or 39% of total
revenues, for the year ended September 30, 2008. The increase in gross profit is primarily driven by increased sales, increased fixed absorption and lower product cost on our LRAD-X product line following some higher start-up production costs
in fiscal 2008 when the product was launched.

##### Table of Contents

Our products have varying gross margins, so product sales mix materially affects gross
profit. In addition, we continue to make product updates and changes, including raw material and component changes that may impact product costs. We do not believe that historical gross profit margins should be relied upon as an indicator of future
gross profit margins.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the year ended September 30, 2009 decreased $1,136,995 to $6,365,646, or 40% of total
revenues, compared to $7,502,641, or 67% of total revenues, for the year ended September 30, 2008. The decrease in expense is primarily due to $555,758 for reduced staffing, a $501,736 decrease in non-cash share-based compensation expense,
$415,504 for decreased legal, audit and accounting fees, $260,339 for reduced selling expenses and travel, and other savings, offset by an increase of $506,393 for bonus expense and related payroll taxes based on meeting company incentive targets,
and a $337,291 increase in commission expense for outside sales representatives.

We incurred non-cash share-based
compensation expenses allocated to selling, general and administrative expenses in the fiscal years ended September 30, 2009 and 2008 of $1,370,417 and $1,872,153, respectively. The decrease in expenses is due to a number of options becoming
fully vested and new options granted at lower fair values due to lower share prices and lower interest rates. In the fourth quarter of fiscal 2009, we incurred $506,393 of bonus expense and related payroll taxes allocated to selling, general and
administrative expenses related to a bonus plan more fully described in Note 8 to our consolidated financial statements.

We
may expend additional resources on marketing our products in future periods which may increase selling, general and administrative expenses.

Research and Development Expenses

Research and development expenses decreased $1,247,502 to $2,106,959,
or 13% of total revenues, for the year ended September 30, 2009, compared to $3,354,461, or 30% of total revenues, for the year ended September 30, 2008. This decrease in research and development expenses was primarily due to a $764,869
reduction in development cost due to costs to develop the new LRAD-X products in 2008, $263,483 for reduced staffing, $281,145 for reduced impairment of patents and $247,843 decrease in non-cash compensation costs, offset by an increase of $337,117
for bonus expense and related payroll taxes based on meeting company targets.

Included in research and development expenses
for the year ended September 30, 2009 was $115,335 of non-cash share-based compensation costs. A total of $363,208 of non-cash compensation costs was included for the year ended September 30, 2008. The decrease in expenses is due to a
number of options becoming fully vested and new options granted at lower fair values due to lower share prices and lower interest rates. In the fourth quarter of fiscal 2009, we incurred $337,116 of bonus expense and related payroll taxes allocated
to research and development expenses related to a bonus plan more fully described in Note 8 to our consolidated financial statements.

During fiscal years 2009 and 2008, we reviewed the ongoing value of our capitalized patent expenses and identified some of these assets as being associated with patents that are no longer consistent with our business strategy. As a result
of this review, we reduced the value of our previously capitalized patents for the fiscal years ended September 30, 2009 and 2008 by $91,470 and $372,615, respectively.

Research and development costs vary period to period 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. In fiscal 2009, research and development expenses were primarily for in-house development. In fiscal 2008, we supplemented our in-house development with
third-party consulting resulting in higher research and development costs in that fiscal year when compared to fiscal 2009. Based on current plans and engineering staffing, we expect fiscal year 2010 research and development costs to be comparable
to expenditures made in fiscal year 2009.

Loss From Operations

Loss from operations was $1,021,849 for the year ended September 30, 2009, compared to a loss from operations of $6,446,373 for the year
ended September 30, 2008. The reduced loss from operations resulted primarily from the increased revenue, improved margins and lower operating expenses.

Other Income (Expense)

During the year ended September 30,
2009, we earned $30,332 of interest income on our cash balances compared to interest income of $171,537 in the year ended September 30, 2008. The lower interest was due to lower average cash equivalent balances and a significant drop in
interest rate due to market conditions. We also incurred $85,440 of other expense for the year ended September 30, 2008 related to liquidated damages in connection with the late filing of our September 30, 2007 Annual Report on Form 10-K.

Net Loss

Our net loss decreased 84% to $1,042,753, or $0.03 per share for the year ended September 30, 2009, compared to a net loss of $6,360,276, or $0.21 per share, for the year ended September 30, 2008. In the year ended
September 30, 2009, we recorded a tax provision of $49,671 as a result of taxable income generated during the year. We generated a federal tax liability due to the Federal alternative minimum tax and a tax liability in the State of California
due to legislation suspending NOL carryforwards for the 2008 and 2009 tax years.

Liquidity and Capital Resources

During the year ended September 30, 2009, we generated $2,578,630 of cash from operating activities, compared to $3,409,932 of cash used
in operating activities in the year ended September 30, 2008. Cash and cash equivalents at September 30, 2009 was $5,102,502 compared to $2,694,869 at September 30, 2008. The increase in cash was primarily the result of increased
sales, lower expenses and tight management of our operating cash flow.

Other than cash and cash equivalents and our balance
of accounts receivable, we have no other unused sources of liquidity at this time.

Principal factors that could affect the
availability of our internally generated funds include:



| |  |  | ability to meet sales projections;
| | - |  | ----------------------------------



| |  |  | government spending levels;
| | - |  | ---------------------------



| |  |  | introduction of competing technologies;
| | - |  | ---------------------------------------



| |  |  | product mix and effect on margins;
| | - |  | ----------------------------------



| |  |  | ability to reduce and manage inventory levels; and
| | - |  | --------------------------------------------------



| |  |  | product acceptance in new markets.
| | - |  | ----------------------------------

Principal factors that could affect our ability to obtain cash from external sources include:



| |  |  | volatility in the capital markets; and
| | - |  | --------------------------------------



| |  |  | market price and trading volume of our common stock.
| | - |  | ----------------------------------------------------

Based on our current cash position, our order backlog, and assuming currently planned expenditures and current level of operations, we believe we have sufficient capital to fund operations for the next
twelve months. However, we operate in a rapidly evolving and often unpredictable business environment that may change the

timing or amount of expected future cash receipts and expenditures. Accordingly, there can be no assurance that we may not be required to raise additional funds through the sale of equity or debt
securities or from credit facilities. Additional capital, if needed, may not be available on satisfactory terms, if at all.

Cash Flows

Operating Activities

Our net cash generated from operating activities was $2,578,630 for the fiscal year ended September 30, 2009 compared to cash used in operating activities of $3,409,932 for the fiscal year ended
September 30, 2008. Cash generated from operating activities for the fiscal year ended September 30, 2009 included the $1,042,753 net loss, reduced by expenses not requiring the use of cash of $2,289,920, a $772,065 decrease in accounts
receivable, a $56,939 decrease in prepaid expenses and a $989,157 increase in accrued liabilities. Cash used in operating activities included a $325,157 increase in inventory, $157,934 increase in warranty settlements and a $3,607 decrease in
accounts payable. Cash used in operating activities for the fiscal year ended September 30, 2008 included the $6,360,276 net loss, reduced by expenses not requiring the use of cash of $3,451,191, a $1,291,426 increase in accounts receivable and
a $158,583 increase in warranty settlements. Cash generated from operating activities included $695,199 decrease in inventory, $192,273 increase in accounts payable, $8,176 decrease in prepaid expenses and a $53,514 increase in accrued liabilities.

At September 30, 2009, we had working capital of $6,858,039 compared to working capital of $6,105,286 at
September 30, 2008. This increase was primarily a result of the positive cash generated from operating activities.

At
September 30, 2009, we had accounts receivable of $1,463,222. This compares to $2,210,526 in accounts receivable at September 30, 2008. The level of trade accounts receivable at September 30, 2009 represented approximately 34 days of
revenues for the year compared to 72 days of revenues at September 30, 2008. The decrease in days was due to a higher level of sales in the fourth quarter of 2008 of $3,857,693, compared to $3,055,073 in the fourth quarter of 2009. Terms with
individual customers vary greatly. We typically require thirty-day terms from our customers. Our receivables can vary dramatically due to overall sales volumes and due to quarterly variations in sales and timing of shipments to and receipts from
large customers and the timing of contract payments.

Investing Activities

We use cash in investing activities primarily for the purchase of laboratory and computer equipment, product tooling, software and investment
in new patents. Cash used in investing activities for capital expenditures was $142,723 and $121,265 in the fiscal years ended September 30, 2009 and 2008, respectively. Cash used for investment in new patents was $38,650 and $189,136 in the
fiscal years ended September 30, 2009 and 2008, respectively. We anticipate continued expenditures for patents and capital expenditures in fiscal 2010 as we continue to invest in new technologies.

Financing Activities

In
the year ended September 30, 2009, we received proceeds of $10,376 from the exercise of stock options. There was no cash provided by financing activities for the year ended September 30, 2008.

Commitments

We are
committed for our facility lease as more fully described in Note 8 to our consolidated financial statements.

##### Table of Contents

We have a bonus plan for employees whereby each can earn a percentage of his or her salary
if we achieve operating income targets established by the board of directors for the fiscal year. The operating income target for bonuses excludes the cost of non-cash share-based compensation expense and includes the cost of the bonus plan. For the
years ended September 30, 2009 and 2008, we incurred bonus expense of $1,085,559 and $-0-, respectively, related to this plan. See Note 8 to our consolidated financial statements.

In April 2009, our Board of Directors adopted a Change in Control Severance Benefit Plan. The Change of Control Plan provides that in the
event of a qualifying termination, each of three participating executives will be entitled to receive (i) a lump sum payment equal to twenty-four months base salary (less applicable tax and other withholdings), (ii) a lump sum
payment equal to the officers target bonus for the year in which the officer is terminated, (iii) continuation of health benefits for twenty-four months and (iv) accelerated vesting of any unvested stock options and other securities
or similar incentives held at the time of termination. A qualifying termination under the Change of Control Plan is any involuntary termination without cause or any voluntary termination for good reason, in each case occurring within three months
before or twelve months after a change of control of the Company.

We entered into an employment agreement in September 2006
with our president and chief executive officer that provides for severance benefits in the form of up to a maximum of six months salary and health benefit continuation if his employment is terminated without cause or he resigns for good
reason. There are no other employment agreements with executive officers or other employees providing future benefits or severance arrangements.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, financings or other
relationships with unconsolidated entities or other persons.

|----------- | ------------------------

We are required to maintain disclosure controls and procedures designed to ensure that material information related to us, including our consolidated subsidiaries, is recorded, processed, summarized and reported within the time periods

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934,
as amended (the Exchange Act)) that are designed to ensure that information required to be disclosed in our Exchange Act Reports is recorded, processed, summarized and reported within the

##### Table of Contents

time periods specified in the SECs rules and forms. Our disclosure controls and procedures are also designed to ensure that information required to be disclosed in our Exchange Act Reports
is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosures. In designing and evaluating the disclosure controls and procedures,
management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the
cost-benefit relationship of possible controls and procedures.

Our management, with the participation of our Chief Executive
Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of September 30, 2009 and, based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as
of the end of the period covered by this report, our disclosure controls and procedures were effective at a reasonable assurance level.

Managements Report on Internal Control Over Financial Reporting

Our management is responsible for
establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f) and 15d-15(f). Under the supervision and with the participation of our management, including our Chief Executive
Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting as of September 30, 2009 based on the guidelines established in Internal Control-Integrated Framework issued
by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Our internal control over financial reporting includes policies and procedures that provide reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements for external reporting purposes in accordance with generally accepted accounting principles in the United States. Based on this evaluation, management has concluded that the Companys internal control over
financial reporting was effective as of September 30, 2009.

Changes in Internal Controls

There have been no changes in our internal control over financial reporting since June 30, 2009 in connection with the evaluation
required by paragraph (d) of Exchange Act Rules 13a-15 or 15d-15, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Our process for evaluating controls and procedures is
continuous and encompasses constant improvement of the design and effectiveness of established controls and procedures and the remediation of any deficiencies which may be identified during this process.

This annual report does not include an attestation report of the companys registered public accounting firm regarding internal control
over financial reporting. Managements report was not subject to attestation by the companys registered public accounting firm pursuant to temporary rules of the SEC that permit the company to provide only managements report in this
annual report.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

American Technology Corporation:

We have audited the accompanying consolidated
balance sheets of American Technology Corporation and Subsidiary (collectively, the Company) as of September 30, 2009 and 2008, and the related consolidated statements of operations, stockholders equity and cash flows for each
of the years then ended. These financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on the financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company was not required to have, nor were we engaged to perform, an audit of its internal
control over financial reporting as of September 30, 2009. Our audit for the year ended September 30, 2009 included consideration of internal control over financial reporting as a basis for designing audit procedures that were appropriate
in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Companys internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements, 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 consolidated financial position of American Technology Corporation and Subsidiary as of September 30, 2009 and 2008, and the consolidated results of their operations and their cash flows for each of the
years then ended, in conformity with accounting principles generally accepted in the United States of America.

The Company has a currently inactive wholly owned subsidiary, American Technology Holdings, Inc., through which the Company intends to
conduct international marketing, sales and distribution activities. The consolidated financial statements include the accounts of this subsidiary after elimination of intercompany transactions and accounts.

LIQUIDITY

The Company has
incurred net losses for each of the last two fiscal years but generated positive cash flow from operating activities in its most recent fiscal year. The Company had working capital of $6,858,039 and cash on hand of $5,102,502 at
September 30, 2009. The Company believes it has adequate financial resources to sustain operations for the next twelve months. The Companys future operating results will depend on product sales levels and other factors, some of which are
beyond managements control. There can be no assurance the Company can sustain positive cash flow or achieve profitability. If required, management has some flexibility to take remedial actions to adjust the level of research and development
and selling and administrative expenses. However, the Company operates in a rapidly evolving and often unpredictable business environment that may change the timing or amount of expected future cash receipts and expenditures. Accordingly, there can
be no assurance that the Company may not be required to raise additional funds through the sale of equity or debt securities or from credit facilities. Additional capital, if needed, may not be available on satisfactory terms, if at all.

USE OF ESTIMATES

The
preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to make estimates and assumptions (e.g., reserves for accounts receivable and inventory, valuation of patents
and warranty reserves) that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and affect the reported amounts of revenues and expenses during the
reporting period. Actual results could materially differ from those estimates.

CONCENTRATION OF CREDIT RISK

The Company maintains cash and cash equivalent accounts with a major Federal Deposit Insurance Corporation (FDIC) guaranteed financial
institution that was enrolled in the U.S. Treasury Departments Temporary Guarantee Program for money market funds. Under this program, the U.S. Treasury guaranteed the $1.00 per share value of fund shares outstanding as of September 19,
2008, subject to certain terms and limitations, through September 18, 2009. Effective October 14, 2008, FDIC deposit insurance was changed to provide full deposit insurance coverage for non-interest bearing deposit transaction accounts
through December 31, 2009. During most of the year ended September 30, 2009, the Companys cash and cash equivalents consisted of guaranteed money market funds. Upon expiration of the money market guarantee on September 18, 2009,
the Company transferred its funds to a non-interest bearing deposit transaction account. At September 30, 2009, all of the Companys cash was fully guaranteed under current FDIC coverage.

##### Table of Contents

The Company sells its products to a large number of geographically diverse customers. The
Company routinely assesses the financial strength of its customers and generally does not require collateral or other security to support customer receivables. At September 30, 2009, accounts receivable from five customers accounted for 15%,
13%, 11%, 11% and 10% of total accounts receivable with no other single customer accounting for more than 10% of the accounts receivable balance. At September 30, 2008, accounts receivable from two customers accounted for 49% and 14% of total
accounts receivable with no other single customer accounting for more than 10% of the accounts receivable balance.

FAIR VALUE OF FINANCIAL
INSTRUMENTS

The carrying amounts of cash and cash equivalents, accounts receivables, accounts payable and accrued
liabilities approximate fair values due to the short maturity of these instruments.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with an original maturity of three months or less, when purchased, to be cash
equivalents.

ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS

The Company carries its accounts receivable at their face amounts, less an allowance for doubtful accounts. On a periodic basis, the Company
evaluates its accounts receivable and establishes an allowance for doubtful accounts for estimated losses considering the following factors when determining if collection of a receivable is reasonably assured: customer credit-worthiness, past
transaction history with the customer, current economic industry trends and changes in customer payment terms. If the Company has no previous experience with the customer, the Company may obtain reports from various credit organizations to ensure
that the customer has a history of paying its creditors. The Company may also request financial information to ensure that the customer has the means of making payment. If these factors do not indicate collection is reasonably assured, revenue is
deferred until collection becomes reasonably assured, which is generally upon receipt of cash. If the financial condition of the Companys customers were to deteriorate, adversely affecting their ability to make payments, additional allowances
would be required. The Company determines allowances on a case-by-case basis. The Company reduced its allowance for doubtful accounts by $22,176 and increased its allowance by $20,470 for the years ended September 30, 2009 and 2008, respectively

CONTRACT MANUFACTURERS

The Company employs contract manufacturers for production of certain components and sub-assemblies. The Company may provide parts and components to such parties from time to time but recognizes no revenue
or markup on such transactions. During fiscal 2009, the Company performed assembly of products in-house using components and sub-assemblies from a variety of contract manufacturers and suppliers.

INVENTORIES

Inventories
are valued at the lower of cost or net realizable value. Cost is determined on a first-in, first-out basis. Inventory is comprised of raw materials, assemblies and finished products intended for sale to customers.The Company periodically
makes judgments and estimates regarding the future utility and carrying value of inventory. The carrying value of inventory is periodically reviewed and impairments, if any, are recognized when the expected future benefit is less than carrying
value. The Company has inventory reserves for estimated obsolescence or unmarketable inventory which is equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market
conditions. The Company increased its inventory reserve by $147,701 and $217,329 during the years ended September 30, 2009 and 2008, respectively, primarily to reserve for excess HyperSonic Sound (HSS) components and certain other slow moving
components resulting from changes in product lines and changes in demand.

##### Table of Contents

EQUIPMENT AND DEPRECIATION

Equipment is stated at cost. Depreciation on machinery and equipment and office furniture and equipment is computed over the estimated useful
lives of three to five years using the straight-line method. Leasehold improvements are amortized over the life of the lease. Upon retirement or disposition of equipment, the related cost and accumulated depreciation or amortization is removed and a
gain or loss is recorded.

INTANGIBLES

Patents and trademarks are carried at cost and, when granted, are amortized over their estimated useful lives, which have been estimated to be 15 years. The carrying value of intangibles is periodically
reviewed and impairments, if any, are recognized when the expected future benefit to be derived from an individual intangible asset is less than its carrying value. The Company wrote off $91,470 and $372,615, of previously capitalized patent costs
during the years ended September 30, 2009 and 2008, respectively.

LEASES

Leases entered into are classified as either capital or operating leases. At the time a capital lease is entered into, an asset is recorded
together with its related long-term obligation to reflect the purchase and financing. At September 30, 2009, the Company had no capital lease obligations.

GUARANTEES AND INDEMNIFICATIONS

Under its bylaws, the Company has agreed
to indemnify its officers and directors for certain events or occurrences arising as a result of the officer or director serving in such capacity. The term of the indemnification period is for the officer or directors lifetime. The maximum
potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. However, the Company has a director and officers liability insurance policy that limits its exposure and enables it
to recover a portion of any future amounts paid. As a result of its insurance policy coverage, the Company does not believe that a material loss exposure related to these agreements is either probable or reasonably estimable. Accordingly, the
Company has no liabilities recorded for these agreements as of September 30, 2009.

The Company enters into
indemnification provisions under (i) its agreements with other companies in its ordinary course of business, typically with business partners, contractors, customers and landlords and (ii) its agreements with investors. Under these
provisions the Company generally agrees to indemnify and hold harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Companys activities or, in some cases, as a result of the indemnified
partys activities under the agreement. The maximum potential amount of future payments the Company could be required to make under these indemnification provisions is unlimited. The Company has not incurred material costs to defend lawsuits or
settle claims related to these indemnification agreements. As a result, the Company does not believe that a material loss exposure related to these agreements is either probable or reasonably estimable. Accordingly, the Company has no liabilities
recorded for these agreements as of September 30, 2009.

REVENUE RECOGNITION

The Company derives its revenue primarily from two sources: (i) product sales (which includes associated engineering and installation),
and (ii) contract and license fees.

Product sales are recognized in the periods that products are shipped to customers
(FOB shipping point) or when product is received by the customer (FOB destination), when the fee is fixed and determinable, when collection of resulting receivables is probable and there are no remaining obligations on the part of the Company. In
limited circumstances, product sales revenues may be recognized prior to shipment when, based on the

##### Table of Contents

Companys evaluation, criteria for recognizing revenue under bill and hold arrangements have been met. During the year ended September 30, 2009, the Company did not recognize any bill
and hold revenue and during the year ended September 30, 2008, recognized $1,080,000 in revenue pursuant to a qualifying bill and hold arrangement.

Revenues from associated engineering and installation contracts are recognized based on milestones or completion of the contracted services.

The Company provides research and development services and licenses its technology to third parties. Revenues from up-front license and
other fees and annual license fees are evaluated for multiple elements but are generally recognized ratably over the specified term of the particular license or agreement. Revenues from ongoing per unit license fees are earned based on units shipped
and are recognized in the period when the ultimate customer accepts the product and collection is reasonably assured.

Deferred revenue balances of $273,954 and $275,509 at September 30, 2009 and 2008, respectively, represent amounts received or billed in connection with contract development and license agreements. On one agreement, royalty revenue is
recognized based on a per unit royalty fee based on the customers unit sales.

SHIPPING AND HANDLING COSTS

Shipping and handling costs are included in cost of revenues. The amount of shipping and handling costs invoiced to customers is included in
revenue. Actual shipping and handling costs were $235,185 and $181,192 for the fiscal years ended September 30, 2009 and 2008, respectively.

ADVERTISING

Advertising costs are charged to expense as incurred. The Company expensed $66,929 and $36,477 for
the years ended September 2009 and 2008, respectively, for advertising costs.

RESEARCH AND DEVELOPMENT COSTS

Research and development costs are expensed as incurred.

WARRANTY RESERVES

The Company warrants its products to be free from
defects in materials and workmanship for a period of one year from the date of purchase. The warranty is generally a limited warranty. The Company currently provides direct warranty service. Some agreements with OEM customers from time to time may
require that certain quantities of product be made available for use as warranty replacements. International market warranties are generally similar to the U.S. market.

The Company establishes a warranty reserve based on anticipated warranty claims at the time revenue from product sales is recognized. Factors affecting warranty reserve levels include the number of units
sold and anticipated cost of warranty repairs and anticipated rates of warranty claims. The Company evaluates the adequacy of the provision for warranty costs each reporting period. In the fiscal year ended September 30, 2009, the Company
increased its reserve by $42,543. The warranty reserve was $277,717 and $235,174 at September 30, 2009 and 2008, respectively. See Note 9 for additional information regarding warranties.

INCOME TAXES

The Company
determines its income tax provision using the asset and liability method. Temporary differences are differences between the tax basis of assets and liabilities and their reported amounts in the



F-10

##### Table of Contents

financial statements that will result in taxable or deductible amounts in future years. A valuation allowance is recorded by the Company to the extent it is more likely than not that a deferred
tax asset will not be realized. Additional information regarding income taxes appears in Note 5, Income Taxes.

COMPREHENSIVE
INCOME

Comprehensive income (loss) consists of net income (loss) and other gains and losses affecting stockholders
equity that under generally accepted accounting principles in the United States, are excluded from reported net income (loss). There were no differences between net loss and comprehensive loss for any of the periods presented.

IMPAIRMENT OF LONG-LIVED ASSETS

Long-lived assets and identifiable intangibles held for use are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of undiscounted expected future cash
flows is less than the carrying amount of the asset or if changes in facts and circumstances indicate, an impairment loss is recognized and measured using the assets fair value.

SEGMENT INFORMATION

The Company presents its business as one reportable
segment due to the similarity in nature of products provided, financial performance measures (revenue growth and gross margin), methods of distribution (direct and indirect) and customer markets (each product is sold by the same personnel to
government and commercial customers, domestically and internationally). The Companys chief operating decision making officer reviews financial information on sound products on a consolidated basis.

NET LOSS PER SHARE

Basic
net loss per share includes no dilution and is computed by dividing net loss by the weighted average number of common shares outstanding for the period. Diluted loss per share reflects the potential dilution of securities that could share in the
earnings of an entity. The Companys losses for the years presented cause the inclusion of potential common stock instruments outstanding to be anti-dilutive. Stock options and warrants exercisable for 6,166,613 and 6,162,893 shares of common
stock were outstanding at September 30, 2009 and 2008, respectively. These securities were not included in the computation of diluted loss per share because of the losses but could potentially dilute earnings per share in future periods.

FOREIGN CURRENCY TRANSLATION

The Companys functional currency is United States (U.S.) dollars as substantially all of the Companys operations use this denomination. Foreign sales to date have been denominated in U.S.
dollars. Transactions undertaken in other currencies, which have not been material, are translated using the exchange rate in effect as of the transaction date. Any exchange gains and losses are included in the statement of operations.

SHARE-BASED COMPENSATION

The Company recognized share-based compensation expense related to stock options issued to employees and directors over the vesting term of the stock-based instrument based on the grant date fair value. Options or stock awards issued to
non-employees who are not directors of the Company are recorded at their estimated fair value at the measurement date, and are periodically revalued as the options vest and are recognized as expense over the related service period.

##### Table of Contents

The Company is in a net operating loss position; therefore, no excess tax benefits from
share-based payment arrangements have been recognized for the year ended September 30, 2009.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 2009, through the issuance of Financial Accounting Standards Board (FASB) Statement No. 168, The FASB
Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles (the ASC or Codification), there became a single official source of authoritative generally accepted accounting principles in the United States (US
GAAP), superseding existing FASB, American Institute of Certified Public Accountants, Emerging Issues Task Force (EITF), and related literature. There is now only one level of authoritative US GAAP. All other literature will be considered
non-authoritative. The Codification does not change US GAAP; instead, it introduces a new structure that is organized in an easily accessible, user-friendly online research system. The Codification is effective for interim and annual periods ending
on or after September 15, 2009. The Company applied the Codification beginning in the fourth quarter of fiscal 2009. The adoption of the Codification did not have an effect on the Companys consolidated financial statements. This new
standard is now codified under ASC 105, Generally Accepted Accounting Principles. In circumstances where revisions or updates to existing standards are required, the FASB will issue an Accounting Standards Update (ASU) on the ASC topic.
All of the Companys financial statement disclosures have been updated in accordance with the Codification. SEC pronouncements are still authoritative for public companies.

Effective April 1, 2009, the Company adopted three accounting standard updates that were intended to provide additional application
guidance and enhanced disclosures regarding fair value measurements and impairments of securities established in ASC 820, Fair Value Measurements and Disclosures (formerly SFAS 157) . They also provide additional guidelines for
estimating fair value in accordance with fair value accounting. The first update, as codified in ASC 820-10-65, Fair Value Measurements and Disclosures (formerly SFAS 157-2), provides additional guidelines for estimating fair value in
accordance with fair value accounting. The second accounting update, as codified in ASC 320-10-65, Debt and Equity Securities (formerly FSP FAS 115-2 and FAS 124-2), changes accounting requirements for other-than-temporary-impairment for
debt securities by replacing the current requirement that a holder have the positive intent and ability to hold an impaired security to recovery in order to conclude an impairment was temporary with a requirement that an entity conclude it does not
intend to sell an impaired security and it will not be required to sell the security before the recovery of its amortized cost basis. The third accounting update, as codified in ASC 825-10-65, Financial Instruments (formerly FSP FAS
No. 107-1 and APB 28-1), increases the frequency of fair value disclosures. These updates were effective for fiscal years and interim periods ended after June 15, 2009. The adoption of these accounting updates did not have any impact on
the Companys consolidated financial statements.

In February 2008, the FASB issued guidance, as codified in ASC 820-10,
Fair Value Measurements and Disclosures, that delayed the effective date of fair value measurements accounting for all non-financial assets and non-financial liabilities, except for items that are recognized or disclosed at fair value in
the financial statements on a recurring basis (at least annually), until the beginning of the first quarter of fiscal 2010. These include goodwill and other non-amortizable intangible assets. The Company adopted this guidance effective
October 1, 2008. The adoption of this update to non-financial assets and liabilities did not have any impact on the Companys consolidated financial statements.

In April 2008, the FASB issued ASC 350-30, General Intangibles Other Than Goodwill (formerly FSP SFAS 142-3). ASC 350-30 provides the factors that should be considered in developing the
renewal or extension assumptions used to determine the useful life of a recognized intangible asset. ASC 350-30 also requires expanded disclosure related to the determination of intangible asset useful lives. It is effective for fiscal years
beginning after December 15, 2008. Earlier adoption is not permitted. The Company does not expect ASC 350-30 to have a material impact on its consolidated financial statements.

##### Table of Contents

In June 2008, the FASB issued ASC 815-40, Derivatives and Hedging; Contracts in
Entitys Own Equity (formerly Emerging Issues Task Force Issue No. 07-5). ASC 815-40 is effective for financial statements issued for fiscal years beginning after December 15, 2008, and interim periods within those fiscal years.
Early application is not permitted. This guidance provides a two-step model to be applied in determining whether a financial instrument or an embedded feature is indexed to an issuers own stock and thus able to qualify for the ASC 815-10
(formerly SFAS No. 133 paragraph 11(a)) scope exception. Based on the Companys review, warrants granted in 2006 contain a strike price adjustment feature, which upon adoption of ASC 815-40 will result in the instruments no longer being
considered indexed to the Companys own stock. Accordingly, our adoption of ASC 815-40 effective October 1, 2009 will cause these warrants to be reclassified from equity to liabilities. Based on assumptions used at October 1, 2009,
the Company expects to record a warrant liability of approximately $748,000 and a cumulative effect adjustment to accumulated deficit of approximately $1,499,000 upon the adoption of this pronouncement. The warrant fair value will be adjusted each
reporting period based on current assumptions, with the change in value being recognized in current earnings, with an offset to the warrant liability. Increases in stock price and stock volatility and decreases in interest rates will increase the
warrant liability and negatively affect the Companys consolidated statement of operations.

In May 2009, the FASB issued
ASC 855-10, Subsequent Events (formerly SFAS No. 165). ASC 855-10 establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are
available to be issued. ASC 855-10 was effective for fiscal years and interim periods ending after June 15, 2009. The implementation of this standard did not have a material impact on the Companys consolidated financial statements. (See
Note 11).

Effective October 1, 2009, the Company adopted a new accounting standard update regarding business
combinations. As codified under ASC 805, Business Combinations (formerly FAS 141R) the update requires the acquisition method to be applied to all transactions and other events in which an entity obtains control over one or more other
businesses, requires the acquirer to recognize the fair value of all assets and liabilities acquired, even if less than one hundred percent ownership is acquired, and establishes the acquisition date fair value as measurement date for all assets and
liabilities assumed. For the Company, this accounting update was effective on a prospective basis for all business combinations for which the acquisition date is on or after October 1, 2009. Since the Company is not contemplating any business
combinations it does not presently expect any impact of adoption on its consolidated financial statements.

ASC 810-10-65,
Consolidation (formerly SFAS 160) establishes accounting and reporting standards for the non-controlling interest in a subsidiary and for the deconsolidation of a subsidiary. It clarifies that a non-controlling interest in a subsidiary
is an ownership interest in the consolidated financial statements. ASC 810-10-65 is effective for our fiscal years beginning after December 15, 2008. The provisions of are applied prospectively upon adoption except for the presentation and
disclosure requirements that are applied retrospectively. The Company has no non-controlling interests and accordingly the adoption of this guidance effective October 1, 2009 is not expected to have a material impact on the Companys
consolidated financial statements.

In September 2009, the FASB issued ASU No. 2009-13, Revenue Recognition (Topic
605)Multiple Deliverable Arrangements (formerly EITF Issue 08-1). This guidance updates the existing multiple-element revenue arrangements guidance currently included under ASC 605-25, which originated primarily from the guidance in EITF
Issue No. 00-21, Revenue Arrangements with Multiple Deliverables. The revised guidance primarily provides two significant changes: 1) eliminates the need for objective and reliable evidence of the fair value for the undelivered element
in order for a delivered item to be treated as a separate unit of accounting, and 2) eliminates the residual method to allocate the arrangement consideration. In addition, the guidance also expands the disclosure requirements for revenue
recognition. ASU 2009-13 will be effective for the first annual reporting period beginning on or after June 15, 2010, with early adoption permitted provided that the revised guidance is retroactively applied to the beginning of the year of
adoption. The Company is currently assessing the future impact of this new accounting update to its consolidated financial statements.

##### Table of Contents

In October 2009, the FASB published ASU 2009-14, Software (Topic 985)-Certain
Revenue Arrangements that Include Software Elements (formerly EITF Issue 09-3) and changes the accounting model for revenue arrangements that include both tangible products and software elements. Under this guidance, tangible products
containing software components and nonsoftware components that function together to deliver the tangible products essential functionality are excluded from the software revenue guidance in Subtopic 985-605, Software-Revenue
Recognition. In addition, hardware components of a tangible product containing software components are always excluded from the software revenue guidance. The guidance in this ASU is effective prospectively for revenue arrangements entered
into or materially modified in fiscal years beginning on or after June 15, 2010. Early adoption is permitted. The adoption of this standard is not expected to have an impact on the Companys financial position and results of operations
since this accounting standard update provides only implementation and disclosure amendments.

RECLASSIFICATIONS

Where necessary, the prior years information has been reclassified to conform to the fiscal 2009 statement presentation.

The Company had raw materials located at supplier locations of $92,240 and $42,243 at
September 30, 2009 and 2008, respectively.

The Company relies on one supplier for film for its HSS product and one
supplier for compression drivers for its LRAD product and is making efforts to obtain alternative suppliers to reduce such reliance. The Companys ability to manufacture its HSS and LRAD product could be adversely affected if it were to lose a
sole source supplier and was unable to find an alternative supplier.

The reserve for obsolescence increased by $147,701 due
to excess HSS components and other slow moving components resulting from changes in demand for the Companys products.

##### Table of Contents

A valuation allowance has been recorded to offset the net deferred tax assets as realization
of such assets has not met the threshold under ASC 740-10, Income Taxes (formerly SFAS 109).

At
September 30, 2009, the Company had net deferred tax assets of $27.2 million. The deferred tax assets are primarily composed of federal and state net operating loss carryforwards (NOL) and federal and state research and development (R&D)
credit carryforwards. At September 30, 2009, the Company, for federal income tax purposes, had net operating loss carryforwards of approximately $62,403,000, which expire through 2029. Included in the net operating loss carryforwards are
deductions from stock options that, if recognized, will be recorded as a credit to additional paid-in capital rather than through the consolidated statement of operations.

Due to uncertainties surrounding the Companys ability to generate future taxable income to realize these assets, a full valuation
allowance has been established to offset net deferred tax assets. The future utilization of the Companys NOL carryforwards to offset future taxable income may be subject to a substantial annual limitation as a result of ownership changes that
could occur in the future. The Company has an estimated $1,383,000 and $1,120,000 of federal and state research and development tax credits, respectively, at September 30, 2009, a portion of which begin to expire in 2010. The Company has not
completed a comprehensive review of the components of its R&D credits. Until this analysis has been completed, the Company has removed the deferred tax assets associated with the tax credit carryforwards from its deferred tax assets recording a
corresponding decrease in the valuation allowance. Once an analysis is completed, the Company plans to update its unrecognized R&D tax benefits. At this time, the Company cannot estimate how much the unrecognized tax benefits may change, if any.

The Company adopted ASC 740-10-25, Income TaxesRecognition (formerly FIN 48) as of October 1, 2007. As
of the date of the adoption, the Company had no unrecognized tax benefits and there were no material changes during the year. Due to the existence of the valuation allowance, future changes in the Companys unrecognized tax benefits will not
impact its effective tax rate. The Companys practice is to recognize interest and/or penalties related to income tax matters in income tax expense. Upon adoption of ASC 740-10-25 on October 1, 2007, the Company did not record any interest
or penalties.

The Company is subject to taxation in the U.S. and various state jurisdictions. Effectively, all of the
Companys historical tax years are subject to examination by the Internal Revenue Service and various state jurisdictions due to the generation of net operating loss and credit carryforwards.

6. STOCKHOLDERS EQUITY

Common
Stock Activity

During the year ended September 30, 2009, the Company issued 17,291 shares of common stock and
obtained gross proceeds of $10,376 in connection with the exercise of stock options.

Preferred Stock

The Company is authorized under its certificate of incorporation and bylaws to issue 5,000,000 shares of preferred stock, $0.00001 par value,
without any further 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. 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.

No shares of preferred stock were outstanding during the fiscal years ended September 30, 2009 or 2008.

7. SHARE-BASED COMPENSATION

Stock
Option Plans

At September 30, 2009, the Company had two equity incentive plans. The 2002 Stock Option Plan (2002
Plan) was terminated with respect to new grants in April 2005 but remains in effect for grants issued prior to the termination. The 2005 Equity Incentive Plan (2005 Plan), as amended, authorizes for issuance as stock options, stock appreciation
rights, or stock awards an aggregate of 3,250,000 new shares of common stock to employees, directors or consultants, plus 1,749,564 shares remaining eligible for issuance under the 2002 Plan for a total plan reserve of 4,999,564. The current plan
reserve at September 30, 2009, net of exercises, allows for the issuance of up to 4,627,372 shares. At September 30, 2009, there were options outstanding covering 85,000 and 3,951,409 shares of common stock under the 2002 Plan and 2005
Plan, respectively.

At September 30, 2009, there were also options outstanding covering 32,000 shares of common stock
from grants outside the stock option plans.

Share-Based Compensation

The Companys employee stock options have various restrictions that reduce option value, including vesting provisions and restrictions
on transfer and hedging, among others, and are often exercised prior to their contractual maturity.

##### Table of Contents

The Company recorded $1,562,633 and $2,258,145 of stock compensation expense for the years
ended September 30, 2009 and 2008, respectively. The weighted-average estimated fair value of employee stock options granted during the year ended September 30, 2009 and 2008 was $0.29 per share and $0.99 per share, respectively, using the
Black-Scholes option-pricing model with the following weighted-average assumptions (annualized percentages):



|                        |  |                           |  |

|                        |  | 2009                      |  | 2008         
|Volatility              |  | 71.0% - 83.0%             |  | 71.0%        
|Risk-free interest rate |  | 1.30% - 2.46%             |  | 2.79% - 3.49%
|Forfeiture rate         |  | 20.0%                     |  | 20.0%        
|Dividend yield          |  | 0.0%                      |  | 0.0%         
|Expected life in years  |  | 3.4 - 4.9                 |  | 3.4 - 4.9    

The dividend yield of zero is based on the fact that the Company has never paid cash
dividends and has no present intention to pay cash dividends. Expected volatility is based on the historical volatility of the Companys common stock over the period commensurate with the expected life of the options. The risk-free interest
rate is based on rates published by the Federal Reserve Board. The expected life is based on observed and expected time to post-vesting exercise. The expected forfeiture rate is based on past experience and employee retention data. Forfeitures are
estimated at the time of the grant and revised in subsequent periods if actual forfeitures differ from those estimates or if the Company updates its estimated forfeiture rate. Such amounts will be recorded as a cumulative adjustment in the period in
which the estimate is changed.

As of September 30, 2009, there was $500,000 of total unrecognized compensation costs
related to outstanding employee stock options. This amount is expected to be recognized over a weighted-average period of 1.3 years. To the extend the forfeiture rate is different from what the Company anticipated, stock-based compensation related
to these awards will be different from the Companys expectations.

|2013                      |  | $ | 5,947  

Employment Agreements

The Company entered into an employment agreement in September 2006 with its president and chief executive officer that provides for severance
benefits in the form of up to a maximum of six months salary and health benefit continuation if his employment is terminated without cause or he resigns for good reason. There are no other employment agreements with executive officers or other
employees providing future benefits or severance arrangements.

Commission and Bonus Plans

The Company has established a bonus plan for its employees, in accordance with their terms of employment, whereby they can earn a percentage
of their salary if the Company achieves certain targeted objectives for net income before taxes. In February 2008, the Compensation Committee of the Board of Directors modified this plan to exclude non-cash, share-based compensation expense from the
calculation of net income. In fiscal 2008, the Company did not pay or accrue any such bonuses. In fiscal 2009, the Company accrued $1,085,559 for bonuses and related payroll taxes based on achieving targeted objectives for the year. The bonuses will
be paid in the quarter ending December 31, 2009.

Change of Control Severance Benefit Plan

In April 2009, the Board of Directors adopted a Change in Control Severance Benefit Plan. The Change of Control Plan provides that in the
event of a qualifying termination, each of three participating executives will be entitled to receive (i) a lump sum payment equal to twenty-four months base salary (less applicable tax and other withholdings), (ii) a lump sum
payment equal to the officers target bonus for the year in which the officer is terminated, (iii) continuation of health benefits for twenty-four months and (iv) accelerated vesting of any unvested stock options and other securities
or similar incentives held at the time of termination. A qualifying termination under the Change of Control Plan is any involuntary termination without cause or any voluntary termination for good reason, in each case occurring within three months
before or twelve months after a change of control of the Company.

Employee Benefit401K Plan

The Company has a defined contribution plan (401(k)) covering its employees. Matching contributions are made on behalf of all
participants at the discretion of the board of directors. During the fiscal years ended September 30, 2009 and 2008, the Company made matching contributions of $32,249 and $34,287, respectively.

Litigation

The Company may
at times be involved in litigation in the ordinary course of business. The Company will also, from time to time, when appropriate in managements estimation, record adequate reserves in the Companys financial statements for pending
litigation. There are no pending material legal proceedings to which the Company is a party or to which any of its property is subject.

Royalties

The Company is obligated to pay a minimum of $1.00 per unit royalty on one electronic component for HSS product. The cost of this royalty has been immaterial in the fiscal years ended September 30,
2009 and 2008.

The Company was obligated to pay a director a 2% royalty on net sales from certain of its technologies. The
royalty obligation terminated in October 2008. No royalties were paid under this agreement in the fiscal year ended September 30, 2008, as the director waived royalties of $14,266.

Guarantees and Indemnifications

The Company undertakes indemnification
obligations in the ordinary course of business related to its products and the issuance of securities. Under these arrangements, the Company may indemnify other parties such as business partners, customers, underwriters, and investors for certain
losses suffered, claims of intellectual property infringement, negligence and intentional acts in the performance of services, and violations of laws including certain violations of securities laws. The Companys obligation to provide such
indemnification in such circumstances would arise if, for example, a third party sued a customer for intellectual property infringement and the Company agreed to indemnify the customer against such claims. The Company is unable to estimate with any
reasonable accuracy the liability that may be incurred pursuant to such indemnification obligations. Some of the factors that would affect this assessment include, but are not limited to, the nature of the claim asserted, the relative merits of the
claim, the financial ability of the parties, the nature and amount of damages claimed, insurance coverage that the Company may have to cover such claims, and the willingness of the parties to reach settlement, if any. Because of the uncertainty
surrounding these circumstances, the Companys indemnification obligations could range from immaterial to having a material adverse impact on its financial position and its ability to continue in the ordinary course of business. The Company has
no liabilities recorded for such indemnities.

The Company establishes a warranty reserve based on anticipated warranty claims at
the time product revenue is recognized. Factors affecting warranty reserve levels include the number of units sold, anticipated cost of warranty repairs and anticipated rates of warranty claims. The Company evaluates the adequacy of the provision
for warranty costs each reporting period.

Details of the estimated warranty liability are as follows:

##### Table of Contents

In the fiscal year ended September 30, 2009, the Company increased its reserve by
$42,543, primarily due to increased product shipments.

10. MAJOR CUSTOMERS, SUPPLIERS, SEGMENT AND RELATED INFORMATION

Major Customers

For the
fiscal year ended September 30, 2009, revenues from one customer accounted for 24% of total revenues. No other single customer represented more than 10% of total revenues. For the fiscal year ended September 30, 2008, revenues from two
customers accounted for 17% and 10% of total revenues with no other single customer accounting for more than 10% of total revenues.

Suppliers

The Company has a large number of components and sub-assemblies produced by outside suppliers, some
of which are sourced from a single supplier, which can magnify the risk of shortages and decrease the Companys ability to negotiate with suppliers on the basis of price. In particular, the Company depends on its HSS piezo-film supplier to
provide expertise and materials used in the Companys proprietary HSS emitters, and on one supplier of compression drivers for its LRAD products. If supplier shortages occur, or quality problems arise, then production schedules could be
significantly delayed or costs significantly increased, which could in turn have a material adverse effect on the Companys financial condition, results of operation and cash flows.

Segment and Related Information

The Company presents its business as one
reportable segment due to the similarity in nature of products marketed, financial performance measures (revenue growth and gross margin), methods of distribution (direct and indirect) and customer markets (each product is sold by the same personnel
to government and commercial customers, domestically and internationally). The Companys chief operating decision making officer reviews financial information on sound products on a consolidated basis.

The following table summarizes revenues by geographic region. Revenues are attributed to countries based on customer location.
