REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders

American Technology Corporation

We have reviewed the accompanying condensed consolidated balance sheet of American Technology Corporation (the “Company”) as of June 30,December 31, 2006 and the related condensed consolidated statements of operations and cash flows for the three and nine month periodsmonths ended June 30,December 31, 2006 and 2005. These interim consolidated financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to such condensed consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We have previously audited, in accordance with the standards of Public Company Accounting Oversight Board (United States), the consolidated balance sheetssheet of American Technology Corporation as of September 30, 2005,2006, and the related consolidated statements of operations, shareholders’ equity, and cash flows for the year then ended (not presented herein); and in our report dated December 27, 2005,January 5, 2007, we expressed an unqualified opinion on those financial statements. As of September 30, 2005,2006, we also conducted an audit of the Company’s internal controls. In our report dated December 27, 2005,January 5, 2007, we expressed an opinion that management’s assessment of the Company did not maintain effective internal control over financial reporting as of September 30, 2005,2006, is fairly stated, in all material respects, based on criteria established inInternal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Also, in our opinion, because of the effect of the material weaknesses described in our opinion, American Technology Corporation did not maintain effective internal control over financial reporting as of September 30, 2005,2006, based on criteria established inInternal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of September 30, 20052006 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

American Technology Corporation, a Delaware corporation (the “Company”), a Delaware corporation, is engaged in design, development and commercialization of highly directional, high clarity and intelligibledirected sound technologies and products. The Company’s principal markets for itsthe Company’s proprietary sound reproduction technologies and products are in North America, Europe and Asia.

In February 2006, the Company incorporated a wholly owned subsidiary, “American Technology Holdings, Inc”.Inc.” The Company plans for this entitysubsidiary to conduct international marketing, sales and promotionaldistribution activities.

2. STATEMENT OF PRESENTATION AND MANAGEMENT’S PLAN

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information. In the opinion of management, the interim consolidated financial statements reflect all adjustments of a normal recurring nature necessary for a fair presentation of the results for interim periods. Operating results for the three and nine month periodsperiod are not necessarily indicative of the results that may be expected for the year. The interim consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited financial statements and notes thereto for the year ended September 30, 20052006 included in the Company’s annual report on Form 10-K, as amended.10-K. Effective October 1, 2006, the Company’s two former business units were aggregated into one reportable segment (See Note 17). Certain amounts reported in prior periods have been reclassified to be consistent with the current period presentation.

The Company incurred net losses of $849,336$513,785 and $3,592,768$770,516 in the three months ended June 30, 2006 and 2005, respectively, and net losses available to common stockholders of $4,250,143 and $8,529,061 in the nine months ended June 30,December 31, 2006 and 2005, respectively. TheManagement has developed an operating plan for fiscal 2007 and believes the Company has financed itsadequate financial resources to execute the plan and to sustain operations primarily through cash generated fromfor the next twelve months. Management’s operating plan includes (a) growing revenues by focusing on direct sales to larger commercial and defense related companies, (b) improving product salesmargins by reducing unit product costs and from financing activities. The Company’s margins from the sale of its products have not yet been sufficient to offset its substantialmonitoring manufacturing overhead, and (c) controlling research and development and selling, marketing and general and administrative expenses. Thecosts. Nevertheless, the Company’s operating results will depend on future product sales levels and other factors, some of which are beyond management’s control. There can be no assurance the Company expectscan achieve positive cash flow or profitability. If required, management has significant flexibility to incur additional operating losses during its fiscal year 2006. Cashtake remedial actions to adjust the level of research and cash equivalents on hand at June 30, 2006 totaled $3,585,353. Baseddevelopment and selling and administrative expenses based on the Company’s current cash balance, cash received from our recent equity financing (See Note 18), order backlog, and assuming currently planned expenditures and current levelavailability of operations, the Company believes it has sufficient capitalresources.

3. RECENT ACCOUNTING PRONOUNCEMENTS

In MarchSeptember 2006, the FinancialSecurities and Exchange Commission (“SEC”) issued Staff Accounting Standards Board (FASB) issued StatementBulletin No. 156, “Accounting for Servicing(SAB 108) which provides interpretive guidance on how the effects of Financial Assets”—an amendmentthe carryover or reversal of FASB Statement No. 140 (SFAS 156), which clarifies when servicing rightsprior year misstatements should be separately accountedconsidered in quantifying a current year misstatement. The guidance is applicable for requires companiesour fiscal 2007. We do not believe SAB 108 will have a material impact on our results from operations or financial position.

In June 2006, the EITF reached a consensus on EITF 06-3, “How Taxes Collected from Customers and Remitted to account for separately recognized servicing rights initially at fair value,Governmental Authorities Should Be Presented in the Income Statement”. EITF 06-3 provides that taxes imposed by a governmental authority on a revenue producing transaction between a seller and gives companiesa customer should be shown in the optionincome statement on either a gross or a net basis, based on the entity’s accounting policy, which should be disclosed pursuant to APB Opinion No. 22, “Disclosure of subsequently accounting forAccounting Policies.” If such taxes are significant, and are presented on a gross basis, the amounts of those servicing rights at either fair value or undertaxes should be disclosed. EITF 06-3 will be effective beginning with the amortization method. FAS 156 is effective forsecond quarter of fiscal years beginning after September 15, 2006. However, companies can early adopt the standard as long as they have not yet issued financial statements, including financial statements for any interim period, for the fiscal year in which early adoption is elected.2007. The Company does not expect SFAS No. 156 to affectis currently evaluating the Company’seffect EITF 06-3 will have on the presentation of its financial condition or results of operations.statements.

In FebruarySeptember 2006, the FASB issued SFAS No. 155, “Accounting157, “Fair Value Measures” (“SFAS No. 157”). SFAS No. 157 defines fair value, establishes a framework for Certain Hybrid Financial Instruments”. Under currentmeasuring fair value in generally accepted accounting principles an entity(GAAP), expands disclosures about fair value measurements, and applies to other accounting pronouncements that holds a financial instrument with an embedded derivative must bifurcate the financial instrument, resulting in the host and the embedded derivative being accounted for separately.require or permit fair value measurements. SFAS No. 155 permits, but157 does not require any new fair value measurements. However, the FASB anticipates that for some entities, to accountthe application of SFAS No. 157 will change current practice. SFAS No. 157 is effective for financial instruments with an embedded derivative at fair value thus negating the need to bifurcate the instrument between its host and the embedded derivative. SFAS No. 155 is effectivestatements issued for fiscal years beginning after SeptemberNovember 15, 2006.2007. The Company does not intend to issue or acquireis currently evaluating the hybrid instruments included in the scope ofeffect SFAS 155 and does not expect the adoption of SFAS 155 to affect the Company’sNo. 157 will have on its financial condition or results of operations.statements.

In June 2005, the FASB issued SFAS No. 154, “Accounting Changes and Error Corrections”, applying to all voluntary accounting principle changes as well as the accounting for and reporting of such changes. SFAS No. 154 replaces APB Opinion No. 20, “Accounting Changes”, and SFAS No. 3, “Reporting Accounting Changes in Interim Financial Statements.” SFAS No. 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. There are two instances where SFAS No. 154 has impacted the Company’s current result of operations due to changes in accounting estimates.

In March 2005, the FASB issued Interpretation No. 47 (“FIN 47”), “Accounting for Conditional Asset Retirement Obligations.” FIN 47 clarifies that an entity must record a liability for a “conditional” asset retirement obligation if the fair value of the obligation can be reasonably estimated. The provision is effective no later than the end of fiscal years ending after December 15, 2005. The Company has determined that FIN 47 has no effect on the Company’s operations at this time.

In June of 2006, the FASB issued Interpretation No. 48 (“FIN 48”)(FIN 48) “Accounting for Uncertainty in Income Taxes.” This Interpretation clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements in accordance with FASB Statement No. 109, “Accounting for Income Taxes.” This Interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. This Interpretation also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The Company does not expect FASB Interpretation No.is currently evaluating the effect FIN 48 to affect the Company’swill have on its financial condition or results of operations.

In December 2004, the FASB issued SFAS No. 153, “Exchanges of Non-monetary Assets, an Amendment of APB Opinion No. 29”, which is effective for non-monetary exchanges occurring in fiscal periods beginning after June 15, 2005. SFAS No. 153 amends APB Opinion No. 29, “Accounting for Non-monetary Transactions” to eliminate the exception for non-monetary exchanges of similar productive assets and replaces it with a general exception for exchanges of non-monetary assets that do not have commercial substance. A non-monetary exchange has commercial substance if the future cash flows of the entity are expected to change significantly as a result of the exchange. The Company does not expect SFAS No. 153 to affect the Company’s financial condition or results of operations.

In November 2004, the FASB issued SFAS No. 151, “Inventory Costs an amendment of ARB 43, Chapter 4.” SFAS No. 151 clarifies that abnormal amounts of idle facility expense, freight, handling costs, and wasted materials (spoilage) should be recognized as current-period charges and requires the allocation of fixed production overheads to inventory based on the normal capacity of the production facilities. SFAS No. 151 is effective for fiscal years beginning after June 15, 2005. The Company has determined that SFAS No. 151 has no effect on the Company’s operations and financial condition at this time.statements.

Notes to Interim Consolidated Financial Statements (unaudited)—(Continued)

Changes in the warranty reserve during the three and nine months ended June 30,December 31, 2006 and 2005 were as follows:

In the fiscal quarteryear ended JuneSeptember 30, 2006, the Company increased theits reserve for potential warranty claims by $89,275 due to additional product in$372,460 for replacement costs associated with a custom unit designed for an OEM brand of HSS units. At December 31, 2006, all costs associated with the field. The Company changed its method for estimating its warranty provision in the quarter ended June 30, 2006. The Company has previously estimated the warranty provision based on rolling estimates of potential costs on revenue activity through the time period product is under warranty coverage. For the fiscal quarter ended June 30, 2006, the provision was calculated based on a forward rate determined on historical experience along with modification for specific estimations. The change in estimate resulted in a decrease to the provision and net loss of approximately $125,000 or less than $(.01) per share for the three and nine months ended June 30, 2006.replacement have been incurred.

9. DERIVATIVE FINANCIAL INSTRUMENTS

In December 2004, the Company entered into a common stock purchase agreement, registration rights agreement and warrant as part of a Committed Equity Financing Facility (CEFF) that was subsequently terminated in July 2005 with no shares issued. As part of the arrangement, the Company issued a warrant to purchase 275,000 shares of its common stock at a price of $8.60 per share. The warrant was unregistered and did not specify how it would be settled prior to registration. The warrant was initially reported as a liability of $843,103 in accordance with Emerging Issues Task Force (EITF) 00-19 “Accounting for Derivative Financial Instruments, Indexed to, and Potentially Settled in a Company’s Own Stock.”Stock” the Company has previously valued some warrants issued in connection with various equity financings as derivative liabilities. The following variables were usedCompany made assumptions and estimates to determineperiodically value its derivative liabilities. Factors affecting the fair valueamount of liability included changes in the warrant under the Black-Scholes option pricing model: volatility of 56%, term of 5.5 years, risk free interest of 2.97% and underlyingCompany’s stock price equal to fair marketand other assumptions. The change in value at the time of issuance. The value washas been recorded as prepaid transaction costs. The warrants were revalued each period asa non-cash income or expense andexpense. For the three months ended December 31, 2005, the Company recorded $1,032,200 as an unrealized gain on derivative revaluation of $451,190 was recorded for the three months ended June 30, 2005,related to warrants and an unrealized gain of $183,259 was recorded for the nine months ended June 30, 2005. In the three months ended June 30, 2005, we recognized a warrant impairment charge of $183,259 representing remaining warrant derivative instrument liability, after reducing prepaid transaction costs when we terminated the equity financing line and the warrant in July 2005. As the warrants were cancelled in July 2005 there is nohad aggregate derivative liability for warrants of $813,800 at September 30, 2005 or thereafter related to this transaction.December 31, 2005.

In July 2005,Effective with the Company’s current first quarter of 2007 the Company entered intoelected early adoption of FASB Staff Position No. EITF 00-19-2 issued on December 21, 2006 (“FSP 00-19-2”). This accounting literature provides guidance on accounting for registration payment arrangements and how to account for related financial instruments. It clarifies that financial instruments, such as warrants, subject to a common stock purchase agreement, registration rights agreement and warrants in connection with a common stock equity financing. In connection with the financing, the Company issued warrants to purchase an aggregate of 1,581,919 shares of common stock consisting of 717,213 ‘A’ Warrants and 864,706 ‘B’ Warrants. The Companypayment arrangement should be accounted for the value of the warrants as a deemed liability in accordance with applicable generally accepted accounting principles without regard to the interpretive guidance incontingent obligation.

10. STOCK-BASED COMPENSATION

Share-Based Payments.In December 2004, the FASB issued Statement of Financial Accounting Standards No. 123 (revised 2004) (SFAS 123(R)), “Share-Based Payment,” which establishes accounting for share-based awards exchanged for employee services and requires companies to expense the estimated fair value of these awards over the requisite employee service period. In March 2005, the U.S. Securities and Exchange Commission issued Staff Accounting Bulletin No. 107 which the Company has applied in the adoption of SFAS 123(R). On April 14, 2005, the U.S. Securities and Exchange Commission adopted a new rule amending the effective dates for SFAS 123(R). In accordance with the new rule, the accounting provisions of SFAS 123(R) were effective for the Company beginning in the quarter ended December 31, 2005.

Under SFAS 123(R), share-based compensation cost is measured at the grant date, based on the estimated fair value of the award at that date, and is recognized as expense over the employee’s requisite service period (generally over the vesting period of the award). The Company has no awards with market or performance conditions. The Company adopted the provisions of SFAS 123(R) on October 1, 2005, the first day of the Company’s fiscal year 2006, using a modified prospective application, which provides for

Under the modified prospective application, the fair values of options issued in prior periods are not revised for comparative purposes, but estimatedpurposes. The valuation provisions of SFAS 123(R) apply to new awards and to awards that are outstanding on the effective date and subsequently modified or cancelled. Estimated compensation expense for awards outstanding at the effective date will beis recognized over the remaining service period using the compensation cost calculated for pro forma disclosure purposes under FASB Statement No. 123, “Accounting for Stock-Based Compensation” (SFAS(FAS 123).

The valuation provisionsOptions 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 in accordance with SFAS 123(R) applyNo. 123 and EITF Issue No. 96-18,Accounting for Equity Instruments That Are Issued to new awardsOther Than Employees for Acquiring or in Conjunction with Selling Goods or Services, and to awards that are outstanding onperiodically revalued as the effective dateoptions vest and subsequently modified or cancelled.are recognized as expense over the related service period.

InOn November 10, 2005, FASB issued FASB Staff Position No. SFASFAS 123(R)-3, “Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards”. The Company is considering whether to adopt the alternative transition method provided in the FASB Staff Position for calculating the tax effects of stock-based compensation pursuant to SFAS 123(R). The alternative transition method includes simplified methods to establish the beginning balance of the additional paid-in capital pool (APIC pool)(“APIC pool”) related to the tax effects of employee stock-based compensation, and to determine the subsequent impact on the APIC pool and statements of cash flows of the tax effects of employee stock-based compensation awards that are outstanding upon adoption of SFAS 123(R).

Share-Based Compensation Information under SFAS 123(R)

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. (Note 11)

Under the provisions of SFAS 123(R) theThe Company recorded $235,500$151,379 and $613,688$188,376 of stock compensation expense for the three and nine months ended June 30,December 31, 2006 and 2005 respectively. A total of $113,080$33,374 and $378,544 for the three and nine months ended June 30, 2006, respectively,$149,673 of this expense relates to awards granted prior year awardsto adoption of SFAS 123(R) and vesting after October 1, 2005. For the three2005, and nine months ended June 30, 2006, $122,420$118,005 and $235,144, respectively, relate$38,703 relates to options granted after the adoption of SFAS 123(R). The weighted-average estimated fair value of employee stock options granted during the three and nine months ended June 30,December 31, 2006 was $2.19 and $2.29$2.90 per share respectively, using the Black-Scholes option-pricingoption pricing model with the following weighted-average assumptions (annualized percentages):

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 expected liferisk-free interest rate is based on observed and expected time to post-vesting exercise. The expected forfeiture rate is based upon past experienceexercise and certain employee retention data.forfeitures of options by employees.

As the amount of share-based compensation expense recognized in quarters ended December 31, 2006 and 2005 is based on awards ultimately expected to vest, it is reduced for estimated forfeitures. SFAS 123(R) requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Pre-vesting forfeitures were estimated to be approximately 20% and 5% infor the third quarter of fiscalquarters ended December 31, 2006 and 2005 based on historical experience. Under the provisions of SFAS 123(R), the Company will record additional expense if the actual forfeiture rate is lower than estimated, and will record a recovery of prior expense if the actual forfeiture is higher than estimated. In the Company’s pro forma information required under SFAS 123 for the periods prior to fiscal 2006, the Company accounted for forfeitures as they occurred.estimated

Since the Company has a net operating loss carryforward as of June 30,December 31, 2006, no excess tax benefit for the tax deductions related to stock-based awards was recognized for the threequarters ended December 31, 2006 and the nine months ended June 30, 2006.2005. Additionally, no incremental tax benefits were recognized from stock options exercised in the three and nine monthsquarter ended June 30,December 31, 2006 whichor 2005. Such recognition would have resulted in a reclassification to reduce net cash provided by operating activities with an offsetting increase in net cash provided by financing activities.

Notes to Interim Consolidated Financial Statements (unaudited)—(Continued)

As of June 30,December 31, 2006, there was $3$1.7 million of total unrecognized compensation cost related to non-vested share-based employee compensation arrangements. The cost is expected to be recognized over a weighted-average period of 3.73.8 years.

Pro Forma Information under SFAS 123 for Periods Prior to Fiscal 2006

Prior to adopting the provisions of SFAS 123(R), the Company recorded estimated compensation expense for employee stock options based upon their intrinsic value on the date of grant pursuant to Accounting Principles Board Opinion 25 (APB 25), “Accounting for Stock Issued to Employees” and provided the required pro forma disclosures of SFAS 123. Because the Company established the exercise price based on the fair market value of the Company’s stock at the date of grant, the stock options had no intrinsic value upon grant, and therefore no estimated expense was recorded prior to adopting SFAS 123(R).

For purposes of pro forma disclosures under SFAS 123 for the three and nine months ended June 30, 2005, the estimated fair value of the stock options was assumed to be amortized to expense over the stock options’ vesting periods. The pro forma effects of recognizing estimated compensation expense under the fair value method on net loss and loss per common share for the three and nine months ended June 30, 2005 were as follows:

The pro forma effects of estimated share-based compensation expense on net income and earnings per common share for the three and nine months ended June 30, 2005 were estimated at the date of grant using the Black-Scholes option-pricing model based on the following assumptions (annualized percentages):

11. STOCKHOLDERS’ EQUITY

Summary

As described in Note 9, the Company elected to record the effects of applying FSP 00-19-2 using the cumulative-effect transition method, which resulted in eliminating the Company’s warrant derivative liability at the beginning of the first quarter, increasing the opening balance of additional paid-in capital by the original value assigned to the warrants with the offsetting cumulative-effect entry to opening accumulated deficit. The cumulative adjustment is not recorded in the statements of operations and previous periods are not adjusted. The impact on previously reported accounts as of September 30, 2006, adjusted effective October 1, 2006, is as follows:

The tax effect of the identified adjustments is not significant since the Company has a full valuation allowance for deferred tax assets.

The following table summarizes changes in equity components from transactions during the ninethree months ended June 30,December 31, 2006:

The 2005 Equity Incentive Plan (“2005 Equity Plan”), authorizes for issuance as stock options, stock appreciation rights, or stock awards an aggregate of 1,500,000 new shares of common stock to employees, directors or consultants. The reserve under the 2005 Equity Plan will include any shares subject to options under the Company’s prior plans that expire or become unexercisable for any reason without having been exercised in full. As a result of the effectiveness of the 2005 Equity Plan, the 2002 Plan is no longer available for new option grants.

At the effective date of the 2005 Equity Plan, approximately 1,660,811 shares were subject to option under prior plans. The total plan reserve, including the new shares and shares currently reserved under prior plans, could not exceedallows for the issuance of up to 3,312,501 shares.

Certain option awards provide for accelerated vesting if there is a change in control (as defined in the Plans).

The following table summarizes information about stock option activity during the ninethree months ended June 30,December 31, 2006:

Options outstanding are exercisable at prices ranging from $2.50$2.60 to $10.06 and expire over the period from 20062007 to 2011 with an average life of 3.513.14 years.

Stock Purchase Warrants

The following table summarizes information about warrant activity during the ninethree months ended June 30,December 31, 2006:

At June 30,December 31, 2006, the following stock purchase warrants were outstanding arising from offerings and other transactions:

The $2.00 warrants, the $3.01 warrants, the $6.36 warrants and the $6.55*These warrants contain certain antidilution rights if the Company sells securities for less than the exercise price, and as a result of the equity financing described in Note 18 below, the exercise price of 492,500 of the $2.00 warrants, and all of the $3.01 warrants, adjustedprice.

Notes to $1.95 and $1.85, respectively. Additionally, the holders of the $6.55 warrants and the $6.36 warrants have the right to a reduction in exercise price to $5.59 and $5.44, respectively. Holders of the $6.36 warrants who elect the reduction in exercise price will receive a proportionate increase in the number of shares under warrant, such that if all holders elect the reduction, such warrants will be exercisable for an aggregate of 838,506 shares.Interim Consolidated Financial Statements (unaudited)—(Continued)

12. NET LOSS PER SHARE

Basic net loss per share includes no dilution and is computed by dividing net loss available to common stockholders, after deduction for cumulative imputed and accreted dividends, by the weighted average number of common shares outstanding for the period. Diluted net loss per share reflects the potential dilution of securities that could share in the earnings of an entity. The Company’s losses for the periods presented cause the inclusion of potential common stock instruments outstanding to be antidilutive. Stock options and warrants exercisable into 4,655,2085,489,688 and 4,442,0445,611,066 shares of common stock were outstanding at June 30,December 31, 2006 and 2005 respectively. These securities are not included in the computation of diluted net loss per share because of the losses, but could potentially dilute earnings per share in future periods.

Net loss available to common stockholders decreased to ($0.03) in the three months ended June 30, 2006 from ($0.17) in the three months ended June 30, 2005, and decreased to ($0.17) in the nine months ended June 30, 2006 from ($0.41) in the nine months ended June 30, 2005. In computing net loss per share, the net loss for the nine months ended June 30, 2005 was increased by $1,796,426 by imputed deemed dividends based on the value of warrants issued and the computed beneficial conversion amount of convertible preferred stock. Such non-cash imputed deemed dividends were not included in the Company’s stockholders’ equity as the Company has an accumulated deficit and therefore were reflected as an increase and a related decrease to additional paid in capital. Amounts are included in net loss available to common stockholders. The imputed deemed dividends were not contractual obligations of the Company to pay such imputed dividends.

The provisions of each of the Company’s series of preferred stock also provided for a 6% per annum accretion in the conversion value (similar to a dividend). Such accretions were not included in the Company’s stockholders’ equity as the Company has an accumulated deficit and therefore they were reflected as an increase and a related decrease to additional paid in capital. These non-cash amounts also increased the net loss available to common stockholders. Net loss available to common stockholders is computed as follows:

13. MAJOR CUSTOMERS

For the three months ended June 30,December 31, 2006, revenues from three customers accounted for 22%24%, 17%,13% and 11% of revenues with no other single customer accounting for more than 10% of revenues.

14. LEASE FOR PRINCIPAL FACILITIES

In December 2005, theThe Company entered into a sublease agreement with Anacomp, Inc., as sublandlord, to subleasesubleases approximately 23,698 square feet of office, warehousing, product assembly, and research space located at 15378 Avenue of Science, San Diego, California 92118. The sublease is for a term commencing January 1, 2006 and expiring May 31, 2011. The agreement provides for a monthly expense of $29,622.50 (representing $1.25 per rentable square foot) during the term. In addition to the monthly base rental expense, the Company iswill be responsible for certain costs and charges specified in the sublease, including the Company’s proportionate share of the building operating expenses and real estate taxes. Costs associated with this move were approximately $280,000, which amount included approximately $248,000 of leasehold improvements.

In addition, the sublease provides that the Company has a right of first refusal on additional space in the building, which contains a total of 68,910 square feet including the Company’s premises. Anacomp also provided a $10,000 tenant improvement allowance towards the completion of lobby improvementspremises and a $50,000 letter of credit in the Company’s favor which the Company may draw upon to the extent necessary to offset any increase in our rent or relocation costs that is incurred due to Anacomp’sthe sublessor’s failure to maintain the lease with the master landlord for the building.

In January 2006, the Company entered into a lease agreement with Priority Properties LLC, to lease approximately 1,700 square feet of office space located in Topsham, Maine, used as a sales and marketing office. The lease is for 12 months and can be renewed for up to five years.

15. 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. Currently, there are no pending material legal proceedings to which the Company is a party or to which any of its property is subject.

16. INCOME TAXES

At June 30,December 31, 2006, a valuation allowance has been provided to offset the net deferred tax asset as management has determined that it is more likely than not that the deferred tax asset will not be realized. At September 30, 2005,2006 the Company had for federal income tax purposes net operating loss carryforwards of approximately $46,972,000,$54,473,000, which expire through 2026,2027 of which certain amounts are subject to significant limitations under the Internal Revenue Code of 1986, as amended.

17. BUSINESS SEGMENT DATA

The Company is engaged in design, development and commercialization of sound, acoustic and other technologies. TheDuring fiscal 2006 the Company’s operations arewere organized into two segments by the end-user markets they serve. The Company’s reportable segments are strategicserved. Late in fiscal 2006, in conjunction with executive management changes and a more diverse customer base, the sales force for all products and end-user markets was consolidated. Effective October 1, 2006, the former two business units that sellwere aggregated into one reportable segment due to the Company’ssimilarity in nature of products into distinct markets. The Commercial Products Group (“Commercial Group”)provided, financial performance measures (revenue growth and gross margin), methods of distribution (direct and indirect) and customer markets and licenses LRAD, HSS, NeoPlanar and other sound products incorporating(each product is sold by the Company’s technologies to customers and end-users that employ audio in consumer, commercial, cruise ship security and other business applications. The Government and Force Protection Systems Group (“Government and Military Group”) markets LRAD and

The former business units are no longer separately managed and no longer considered separate business units. The Company’s chief operating decision making officer reviews financial information on sound products on a consolidated basis and not by the expanding force protection and police and similar private security markets.

Effective October 1, 2005,end-user markets served. Accordingly, the Company changed the composition ofhas reclassified its two reportable business segmentsprior period financial results to reflect a shift in management responsibility for the commercial maritime market from the Government and Military Groupconform to the Commercial Group. For the three and nine months ended June 30, 2005, sales to commercial maritime customers were included in the Government and Military Group, but have been reclassified to the Commercial Group to be consistent with the current period presentation.

The accounting policiespresentation of the segments are the same as those described in the summary of significant accounting policies. The Company does not allocate operating expenses or assets between its twoone reportable segments. Accordingly the measure of profit for each reportable segment is gross profit.segment.

Summarized below are the revenues and gross profit (loss) for our business units:

18. SUBSEQUENT EVENTSREGISTRATION PAYMENT OBLIGATION

In connection with registration rights agreements entered into with the sale of common stock and warrants in July 2003, July 2005 and August 2006, the Company sold 4,870,512 shares of common stock at a purchase price of $1.95 per share. The Company also issued warrants to the investors to purchase 1,948,205 shares of common stock at an exercise price of $2.67 per share. The warrants are exercisable from February 7, 2007 until August 6, 2010.

The gross proceeds from this financing were $9,497,498 million. The Company incurred financing and closing costs of approximately $570,000. The Company will use net proceeds for working capital purposes. The Company entered into a registration rights agreement with the investors and agreed to prepare and file, within 30 days following the issuance of the securities, a registration statement covering the resale of the shares of common stock sold and the common stock issuable upon the exercise of the warrants. Failure to have an effective registration statement within 90 days obligates the Companymay be obligated to pay liquidated damages if it fails to maintain the purchasers in the amount of 0.0165%availability of the gross proceedsrespective registration statements declared effective in August 2003, September 2005 and September 2006. The liquidated damages are computed as a daily percentage of the original purchase price based on a ratio of registrable securities (shares and warrants) still held by each investor for each day after a 20 trading day grace period that a registration statement is unavailable for use.

Liquidated damages are payable in cash and accrue interest of the gross proceeds12% per day thereafter, but not to exceed a total of 20% of the purchase price paid by each investor.annum on late payments.

The Company filed its Form 10-K for the fiscal year ended September 30, 2006 past the extended due date of December 29, 2006. As of December 31, 2006 it was considered probable that the Company would be obligated for liquidated damages, so the Company has also agreedaccrued as a financing expense $32,890, for such liquidated damages calculated pursuant to submit the financing to a vote of its stockholders for approval prior to June 2007. The Company further agreed that, subject to certain exceptions, if during the period until one year following effectiveness of the registration statement the Company sells shares of its common stock, in a private placement or in a public offering using a Form S-3, the purchasers will have certain rights of first refusal to participate in the financing. The Company has also agreed to indemnify the purchasers for certain losses.

The warrants contain provisions that would adjust the exercise price, and in inverse proportion adjust the number of shares subject to the warrant, in the event the Company pays or effects stock dividends or splits, or in the event the Company sells shares of its common stock at a purchase price, or options or warrants to purchase shares of its common stock having an exercise price, less than the exercise price of the applicable warrant. The warrants also feature a net exercise provision, which enables the holder to choose to exercise the warrant without paying cash by surrendering shares subject to the warrant with a market value equal to the exercise price. This right is available only if a registration statement covering the shares subject to the warrants is not available after it is initially declared effective.

Effective July 31, 2006 the Company closed its facility in Carson City, Nevada and consolidated production operations of its Neoplanar products and certain related assets into its San Diego facility. No remaining lease obligations pertain to this facility.agreements.

Reclassification of Prior Period Business Segment Data

The following discussion and analysis gives effect to the reclassification of prior period business segment data described in Note 17 to the unaudited interim consolidated financial statements for the periods ended June 30, 2006 and June 30, 2005 contained herein. Accordingly, certain of the data set forth in this section is not comparable to discussions and data in our previously filed quarterly reports for corresponding periods.

Overview

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

In fiscal year 2005, we completed the commercialization of four proprietary directed sound technologies, recording revenues from each. During the first half of fiscal year 2006, ourOur HSS^® H-450 continued to gainand HSS H-460 products are gaining acceptance from digital signage and networked narrowcasting display providers as in-store narrowcasted networks proliferate in retail chains throughout the U.S. and abroad. We have experienced increased revenues from the sale of LRADadded new LRAD™ and NeoPlanar^® products toand accessories for our customers, in the commercial marine, yachting and energy industries. LRAD has shown to be an effective long range communications and non-lethal tool used in force protection security and long range communications. With a key addition to our executive management team over the last two months, Mr. Charles W. Peacock, Vice President Government and Military Group, we believe we are refining our approach to the sales, marketing and licensing of directed sound to expand our leadership position in the markets we serve.including

performance points to attract serious market interest. Accelerating our product sales and revenue growth will require organizational discipline, effective processes and controls, improved customer focus, and a new, targetedsustained marketing strategy forpush of our company and products. We are focused on these areas of our business while also containing costs.

Overall Performance for the ThirdFirst Quarter of Fiscal 20062007

For the thirdour first fiscal quarter ended June 30,December 31, 2006:

Recent Developments

In August 2006 we completed an institutional financing providing gross proceeds of approximately $9.5 million. After paying financing and closing costs estimated at $570,000, we expect to use the net proceeds for general working capital. (see Note 18)

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 expect to incur additional operating losses during fiscal 2006. Cash and cash equivalents on hand at June 30, 2006 was $3,585,353. Based on our current cash position, cash received from our recent equity financing, 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. Our various technologies are high risk in nature. However, we believe we have a solid technology and product foundation for business growth over the next several years. We have significant new technologies and products in various

stages of development. We also believe we have strong market opportunities, particularly given the dramatic growth and acceptance of digital signage requiring the use of our directed sound products and the continuing global threats to both governments and commerce where our LRAD products have proven to be effective at hailing and notification for force protection.

Critical Accounting Policies

We have identified a number of accounting policies as critical to our business operations and the understandings of our results of operations. These are described in our consolidated financial statements located in Item 1 of Part I, “Financial Statements,” and in Management’s Discussion and Analysis of Financial Condition and Results of Operations in our Annual Report onof Form 10-K for the year ended September 30, 2005.2006. The impact and any associated risks related to these policies on our business operations is discussed throughout Management’s Discussion and Analysis of Financial Condition and Results of Operations when such policies affect our reported and expected financial results.

Effective October 1, 2005, we adopted the provisions of Statement of Financial Accounting Standards Statement No. 123 (revised 2004), Share-Based Payment (SFAS 123(R)). SFAS 123(R) was issued by the Financial Accounting Standards Board (FASB) on December 16, 2004. In March 2005, the U.S. Securities and Exchange Commission issued Staff Accounting Bulletin No. 107 which the Company has applied in the adoption of SFAS 123(R). On April 14, 2005, the U.S. Securities and Exchange Commission adopted a new rule amending the effective dates for SFAS 123(R). In accordance with the new rule, the accounting provisions of SFAS 123(R) are effective for our company beginning in the quarter ended December 31, 2005. We grant options to purchase our common stock to our employees, directors and consultants under our stock option plans. The benefits provided under these plans are share-based payments subject to SFAS 123(R) and use the fair value method to account for share-based payments with a modified prospective application which provides for certain changes to the method for valuing share-based compensation.

SFAS 123(R) is based on the underlying accounting principle that compensation cost resulting from share-based payment transactions be recognized in financial statements at fair value. SFAS 123(R) replaces FASB No. 123, “Accounting for Stock-Based Compensation” (SFAS 123) and supersedes Accounting Principles Board Opinion 25. SFAS 123, as originally issued in 1995, established as preferable, but did not require, a fair-value-based method of accounting for share-based payment transactions with employees. SAB 107 expresses views of the SEC staff regarding the interaction between SFAS 123(R) and certain SEC rules and regulations and provides the staff’s views regarding the valuation of share-based payment arrangements for public companies.

In summary SFAS 123(R) requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award (with limited exceptions). That cost is recognized over the period during which an employee is required to provide requisite service in exchange for the award (usually over the vesting period). No compensation cost is recognized for equity instruments for which employees do not render the requisite service, i.e. forfeitures are adjusted to actual.

The grant-date fair value of employee share options and similar instruments is to be estimated using option-pricing models adjusted for the unique characteristics of those instruments. If an equity award is modified after the grant date, incremental compensation cost will be recognized in an amount equal to the excess of the fair value of the modified award over the fair value of the original award immediately before the modification.

Excess tax benefits, as defined by SFAS 123(R), are to be recognized as an addition to paid-in capital. Cash retained as a result of any excess tax benefits is to be presented in the consolidated statement of cash flows as financing cash inflows. The write-off of deferred tax assets relating to unrealized tax benefits associated with recognized compensation cost is to be recognized as income tax expense unless there are excess tax benefits from previous awards remaining in paid-in capital to which it can be offset.

As of the required effective date, all public entities that used the fair-value-based method for disclosure under SFAS 123 are to apply SFAS 123(R) using a modified version of prospective application. Under that transition method, compensation cost is recognized on or after the required effective date for the portion of outstanding awards, for which the requisite service has not yet been rendered, based on the grant-date fair value of those awards calculated under SFAS 123 for pro forma disclosures. Total compensation cost for our share-based payments recognized in three and nine months ended June 30, 2006 was $235,500 and $613,688, respectively. As of June 30, 2006, $3 million of total unrecognized compensation costs related to unvested awards is expected to be recognized over a weighted average period of 3.7 years.

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. The estimates affect the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions.

Results of Operations for the Three Months Ended June 30, 2006 and 2005

Revenues

Total revenuesRevenues for the three months ended June 30,December 31, 2006 were $3,164,779,$3,904,205, representing a 127%104% increase from $1,393,797$1,915,750 in revenues for the three months ended June 30,December 31, 2005. Total revenuesRevenues for the three months ended June 30,December 31, 2006 included $3,086,599$3,762,124 of product sales and $78,180$142,081 of contract, license and licenseother revenues. Total revenuesRevenues for the three months ended June 30,December 31, 2005 consisted of $1,378,648included $1,839,969 of product sales and $15,149$75,782 of contract, license and licenseother revenues. The increase in revenues was due to $1.1 million ofincreased sales of our HSS 450 intoLRAD products to a growing number of customers. Our marketing efforts, successful product deployments and extensive product demonstrations have contributed to increased market awareness and customer acceptance of the digital signage and in-store broadcasting markets and $182,000 salesforce protection capabilities of our Neoplanar product into the military market and increased LRAD sales. Our revenues are highly dependent on the timing of large orders from a small number of customers.products. We expect continued uneven quarterly revenues in future periods due to the lack of established markets for our proprietary products.

Revenues by Business Segment

Our operations are organized into two segments by the end-user markets they serve. Our reportable segments are strategic business units that sell our products into distinct markets. The Commercial Products Group (Commercial Group) markets and licenses LRAD, HSS, NeoPlanar and other sound products incorporating our technologies to customers and end-users that employ audio in consumer, commercial and other business applications. The Government and Force Protection Systems Group (Government and Military Group) markets LRAD and NeoPlanar products to government and military customers and to the expanding force protection, police and similar private security markets. Effective October 1, 2005, we changed the composition of our two reportable business segments to reflect that management had shifted responsibility for the commercial maritime and passenger cruise line markets from the Government and Military Group to the Commercial Group. For the three and nine months ended June 30, 2005, sales to customers in these markets were included in the Government and Military Group, but have been reclassified to the Commercial Group to be consistent with the current period presentation.

Commercial Group—The Commercial Group reported revenues of $1,689,634 for the three months ended June 30, 2006, representing a 355% increase from revenues of $370,897 for the three months ended June 30, 2005. Sound product revenues were $1,626,954 and $370,897, and contract and license revenues were $62,680 and $0 for the three months ended June 30, 2006 and 2005, respectively. The increase in sound product revenues resulted primarily from increased HSS sales into the digital signage and in-store broadcasting markets. In fiscal 2005, we entered into a license agreement which contained multiple elements. Based on our evaluation of the agreement under the guidance of EITF Issue No. 00-21 we determined this arrangement does not qualify for multiple element accounting and revenue will be recognized ratably over the three year term of the agreement. For the three months ended June 30,December 31, 2006, we recognized $54,167 in contract revenuesrevenue representing the ratable earned revenue under the three year agreement. At June 30,December 31, 2006, $122,222$52,778 remained unearned under this agreement and has been recorded as deferred revenue. At June 30,December 31, 2006, we had aggregate deferred license revenuesrevenue of $410,824$332,355 representing amounts collected from Commercial Group license agreements in advance of recognized earnings. Although we anticipate additional license revenues in fiscal year 20062007 from existing and new arrangements, this revenue component is subject to significant variability based on the timing, amount and recognition of new arrangements, if any.

Government and Military Group—Government and Military Group revenues for the three months ended June 30, 2006, were $1,475,145 compared to $1,022,900 for the three months ended June 30, 2005, representing a 44% increase. Sound product revenues were $1,459,645 and $1,007,752 and contract and license revenues were $15,500 and $15,148 for the three months ended June 30, 2006 and 2005, respectively. The increase in revenues resulted from increased sales of our Neoplanar product line and LRAD product for the three months ended June 30, 2006.

Our order backlog was approximately $7,200,000$7,297,000 at June 30,December 31, 2006 which includes $3,773,000 of orders with scheduled delivery dates after September 30, 2006. Our order backlog wasand approximately $660,000$6,340,000 at June 30,December 31, 2005. Backlog orders are subject to modification, cancellation or rescheduling by our customers. Future shipments may also be delayed due to production delays, component shortages and other production and delivery related issues.

Gross Profit

Gross profit for the three months ended June 30,December 31, 2006 was $1,045,534,$1,956,292, or 33%50% of total revenues, compared to $358,674,$1,064,138, or 25%56% of total revenues, for the three months ended June 30,December 31, 2005. The absolute increase in gross profit both absolute and as a percentage of total revenues, was principally the result of the increased sales of our products offsetting fixed overhead costs.

Gross profit for our Commercial Group was $338,761 and $23,914 for the three months ended June 30, 2006 and 2005, respectively. Increased sales of LRAD products inand the three months ended June 30, 2006 were the primary contributor to the increasedecrease in gross profit for our Commercial Group. Gross profit for our Government and Military Group was $706,773 for the three months ended June 30, 2006, or 47% of total revenues, compared to $334,760 for the three months ended June 30, 2005 or 32% of total revenues. The increase in gross profit, both absolute and as a percentage of total revenues was principally due to increased salesprimarily the result of our LRAD product line to Government and Military Group customers. Gross profit percentage is highly dependent on sales prices, volumes, purchasing costs and overhead allocations.mix.

Our products have varying gross margins, so product sales mix will materially affect gross profits. 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 three months ended June 30,December 31, 2006 decreased $672,769$363,055 to $2,147,608,$2,012,069 or 67%52% of total revenues, compared to $2,820,377,$2,375,124, or 202%124% of total revenues, for the three months ended June 30,December 31, 2005. The major component changesdecrease in selling general and administrative expenses were: $194,872was primarily attributed to: $374,575 for increaseddecreased personnel and related expenses; $142,446 for decreased consulting and accounting expenses offset by decreased legal and related feesprimarily as a result of $345,188; $236,201 in reduced demonstration equipment and trade show activity; $159,839 in reduced consulting, accounting, and auditing expenses relating toinitial costs assessing internal control over financial reporting under Section 404 of the Sarbanes-Oxley Act of 2002 for the first time in the first quarter of fiscal 2006; and the internal control deficiencies as discussed in Part I, Item 4 of this report, and $109,615$94,366 for decreased travel, commissions, demonstration equipment and commissions.trade show activity. These reductions were offset by an increase in legal, accounting and consulting fees of $425,647 associated with a voluntary review of historical stock option and stock grants and the related restatement of financial statements as more fully described in our Annual Report on Form 10-K for the fiscal year ended September 30, 2006.

We may expend additional resources on marketing our products in future periods which may increase selling, general and administrative expenses. During fiscal year 2005,2006, we incurred a significant amount of outside consultant costs and audit fees to comply with the Sarbanes-Oxley Act (particularly Section 404), relating to management assessment of internal control over financial reporting. WeIn addition to the expenses incurred in the voluntary review of historical stock option and stock grants in the first quarter of fiscal 2007, we expect to continue to incur significant additional audit fees and other costs in during the balance of fiscal year 20062007 to comply with the Sarbanes-Oxley Act and to improve our internal control over financial reporting and procedures in our accounting organization. We do not currently have an estimate of these future costs, but we anticipate we will increase spending for increased staffing, outside consultants and legal and audit costs.

Research and Development Expenses

Research and development expenses decreased $823,875$24,478 to $459,904,$541,515, or 14% of total revenues, for the three months ended June 30,December 31, 2006, compared to $1,283,779,$565,993, or 92%30% of total revenues, for the three months ended June 30,December 31, 2005. This decrease in research and development expenses wasis primarily due to $510,860 decreasea $17,255 increase in personnelconsulting and related expenses; $166,395expenses, offset by a $48,418 decrease in prototype component acquisition, fabrication and testing for new products developed during fiscal year 2005; $89,403 decrease in outside consulting fees associated with product design; $18,253 in reduced travel expenses and $14,189 decrease in small tools, equipment and supplies.2006.

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. We completed and introduced significant new products in fiscal year 2005,2006, including our HSS H450H460 product, our LRAD-R, LRAD Scram Cart and our portable LRAD500.LRAD 100. With the completion of these major projects, and based on current plans and reduced engineering staffing, we expect fiscal year 20062007 research and development costs to be lower thancomparable with fiscal year 2005.2006.

Share-Based Compensation

Effective at the beginning of fiscal year 2006, we adopted Statement of Financial Accounting Standards No. 123(R) (“SFAS 123(R) ,and”), “Share-Based Payment,” and elected to adopt the modified prospective application method. SFAS No. 123(R) requires us to

use a fair-valued based method to account for share-based compensation. Accordingly, share-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the employees’ requisite service period. Total compensation cost for our share-based payments forin the three months ended June 30,first quarter of fiscal 2006 was $235,500.$151,379. Cost of revenues, selling, general and administrative expense, and research and development expense forin the three months ended June 30,first quarter of fiscal 2006 include share-based compensation of $15,022, $80,535, $108,726$17,943, $124,183 and $31,217,$9,253, respectively. As of June 30,December 31, 2006, $3$1.7 million of total unrecognized compensation costs related to nonvested awards is expected to be recognized over a weighted average period of 3.73.8 years. See Note 10 “Stock-Based Compensation,” in the Notes to Interim Consolidated Financial Statements (unaudited)interim consolidated financial statements for further discussion.

Loss from Operations

Loss from operations was $1,561,978$597,292 for the three months ended June 30,December 31, 2006, compared to a loss from operations of $3,745,482$1,876,979 for the three months ended June 30,December 31, 2005. The decrease in loss from operations resulted primarily from the increase in revenues and gross margin.profit as a result of increased LRAD deliveries as well as a significant decrease in personnel costs due to a restructuring of the management team in the fourth quarter of fiscal 2006. These decreases were offset in part by the $425,647 of expenses incurred in the voluntary review of historical stock option and stock grants.

Other Income (Expense)

During the three months ended June 30,December 31, 2006, we earned $43,900$116,397 of interest income on our cash balances and incurred $558accrued $32,890 of interest expense. Otherfinancing expense for liquidated damages associated with the three monthstemporary unavailability of resale registration statements resulting from the filing of our Form 10-K for the fiscal year ended JuneSeptember 30, 2006 included $669,300 related topast the change in the fair valueextended due date of warrants issued in connection with our July 2005 sale of common stock and warrants.

At June 30, 2006, our long term derivative warrant instrument was $484,000. We must make certain assumptions and estimates to value our derivative warrant instrument periodically. Factors affecting the amount of this liability include changes in our stock price and other assumptions. The change in value is non-cash income or expense and the changes in the carrying value of derivatives can have a material impact on our financial statements each period. The derivative liability associated with our July 2005 sale of common stock and warrants may be reclassified into stockholders’ equity upon warrant exercise, expiration or other events, and the timing of such events may be outside our control.December 29, 2006.

During the three months ended June 30,December 31, 2005, we earned $16,687$74,623 of interest on our cash balances, and incurred $131,904$360 of interest expense and $451,190recognized $1,032,200 of unrealized non-cash gain on derivative revaluation associatedrevaluation. As described in Note 9 and Note 11 to the interim consolidated financial statements, we elected to record the effects of applying FSP 00-19-2 using the cumulative-effect transition method, which resulted in eliminating the warrant derivative liability at the beginning of the first quarter of the current fiscal year, increasing the opening balance of additional paid-in capital by the original value assigned to the warrants with a derivative instrument issuedthe offsetting cumulative-effect entry to opening accumulated deficit. The cumulative adjustment is not recorded in December 2004the consolidated statement of operations and cancelled in July 2005 and $183,259 of warrant impairment expense.prior periods are not adjusted.

Net Loss

NetThe net loss for the three months ended June 30,December 31, 2006 decreased nearly 76%was $513,785, compared to $849,336 from a net loss of $3,592,768$770,516 for the three months ended June 30,December 31, 2005. We had no income tax expense for either of thesethe periods presented.

Net Loss Available to Common Stockholders

Net loss available to common stockholders was $849,336 or $0.03 per share for the three months ended June 30, 2006, compared to a net loss available to common stockholders of $3,592,768 or $0.17 for the three months ended June 30, 2005 respectively.

Results of Operations for the Nine Months Ended June 30, 2006 and 2005

Revenues

Total revenues for the nine months ended June 30, 2006 were $6,529,786, representing a 24% decrease from $8,620,104 in revenues for the nine months ended June 30, 2005. Total revenues for the nine months ended June 30, 2006 included $6,287,812 of product sales and $241,974 of contract and license revenues. Revenues for the nine months ended June 30, 2005 consisted of $8,539,855 of product sales and $80,249 of contract and license revenues. The decrease in revenues was due to reduced sales by our Government and Military Group. The prior year period revenues included $4.9 million on one large military order. This was partially offset by an increase in our Commercial Group sales due to the launch of our HSS 450 into the digital signage and in-store broadcasting segments. Our revenues are highly dependent on the timing of large orders from a small number of customers. We expect continued uneven quarterly revenues in future periods due to the lack of established markets for our proprietary products.

Revenues by Business Segment

Commercial Group—The Commercial Group reported revenues of $3,828,022 for the nine months ended June 30, 2006, representing a 172% increase from revenues of $1,403,420 for the nine months ended June 30, 2005. Sound product revenues were $3,654,266 and $1,403,420, and contract and license revenues were $173,756 and $0 for the nine months ended June 30, 2006 and 2005, respectively. The increase in sound product revenues resulted primarily from increased LRAD sales.

In fiscal 2005, we entered into a license agreement which contained multiple elements. Based on our evaluation of the agreement under the guidance of EITF Issue No. 00-21 we determined this arrangement does not qualify for multiple element accounting and revenue will be recognized ratably over the three year term of the agreement. For the nine months ended June 30, 2006, we recognized $162,500 in contract revenues representing the ratable earned revenue under the three year agreement. At June 30, 2006, $122,222 remained unearned under this agreement and has been recorded as deferred revenue. At June 30, 2006, we had aggregate deferred license revenues of $410,824 representing amounts collected from Commercial Group license agreements in advance of recognized earnings. Although we anticipate additional license revenues in fiscal year 2006 from existing and new arrangements, this revenue component is subject to significant variability based on the timing, amount and recognition of new arrangements, if any.

Government and Military Group—Government and Military Group revenues for the nine months ended June 30, 2006, were $2,701,764 compared to $7,216,684 for the nine months ended June 30, 2005, representing an 62% decrease. Sound product revenues were $2,633,547 and $7,136,435 and contract and license revenues were $68,217 and $80,249 for the nine months ended June 30, 2006 and 2005, respectively. The decrease in revenues resulted from reduced orders for the nine

months ended June 30, 2006. Included in product revenues for the nine months ended June 30, 2005 is a $4.9 million order received in December 2004 for delivery of LRAD units to the US Army.

Gross Profit

Gross profit for the nine months ended June 30, 2006 was $2,297,886, or 35% of total revenues, compared to $4,527,704, or 52% of total revenues, for the nine months ended June 30, 2005. The decrease in gross profit, both absolute and as a percentage of revenues, was principally the result of the decreased sales of LRAD products.

Gross profit (loss) for our Commercial Group was $1,054,733 and $(118,724) for the nine months ended June 30, 2006 and 2005, respectively. Increased sales of LRAD products in the nine months ended June 30, 2006 were the primary contributor to the increase in gross profit for our Commercial Group. The gross loss for the nine months ended June 30, 2005 was primarily a result of insufficient margins earned on HSS product sales to offset the allocation of manufacturing overhead to this segment of our business. Gross profit for our Government and Military Group was $1,243,151 for the nine months ended June 30, 2006 or 46% of revenues, compared to $4,646,428 for the nine months ended June 30, 2005 or 64% of revenue. The decrease in gross profit, both absolute and as a percentage of total revenues, was due to lower sales of LRAD product line to Government and Military Group customers. Gross profit percentage is highly dependent on sales prices, volumes, purchasing costs and overhead allocations.

Our products have varying gross margins, so product sales mix will materially affect gross profits. 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 nine months ended June 30, 2006 decreased $237,317 to $6,569,816 or 100% of total revenues, compared to $6,807,133, or 78% of total revenues, for the nine months ended June 30, 2005. The major component changes in selling general and administrative expenses were $617,417 for increased personnel and related expenses; $217,933 for increased consulting, accounting, and auditing expenses primarily as a result of Section 404 of the Sarbanes-Oxley Act of 2002 and the internal control deficiencies as discussed in Part I, Item 4 of this report and $59,557 for increased SEC reporting costs and public relations, offset by $728,053 in decreased legal and related fees; $317,762 in reduced demonstration equipment and trade show activity and $130,431 for decreased travel and commissions.

We may expend additional resources on marketing our products in future periods which may increase selling, general and administrative expenses. During fiscal year 2005, we incurred a significant amount of outside consultant costs and audit fees to comply with the Sarbanes-Oxley Act (particularly Section 404), relating to management assessment of internal control over financial reporting. We expect to incur significant additional audit fees and other costs in fiscal year 2006 to comply with the Sarbanes-Oxley Act and to improve our internal control over financial reporting and procedures in our accounting organization. We do not currently have an estimate of these future costs, but we anticipate we will increase spending for increased staffing, outside consultants and legal and audit costs.

Research and Development Expenses

Research and development expenses decreased $2,696,262 to $1,528,114, or 23% of total revenues, for the nine months ended June 30, 2006, compared to $4,224,376, or 49% of total revenues, for the nine months ended June 30, 2005. This decrease in research and development expenses was primarily due to $1,725,901 decrease in personnel and related expenses, of which $181,651 was non-cash compensation associated with an extension of time to exercise stock options; $615,745 decrease in prototype component acquisition, fabrication and testing for new products developed during fiscal year 2005; $121,466 decrease in outside consulting fees associated with product design; $73,724 decrease in small tools, equipment and supplies; and $41,669 in reduced travel expenses.

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. We completed and introduced significant new products in fiscal year 2005, including our HSS H450 product and our portable LRAD500. With the completion of these major projects, and based on current plans and reduced engineering staffing, we expect fiscal year 2006 research and development costs to be lower than fiscal year 2005.

Share-Based Compensation

Effective at the beginning of fiscal year 2006, we adopted Statement of Financial Accounting Standards No. 123(R) (“SFAS 123(R)”), “Share-Based Payment,” and elected to adopt the modified prospective application method. SFAS No. 123(R) requires us to use a fair-valued based method to account for share-based compensation. Accordingly, share-based compensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the employees’ requisite service period. Total compensation cost for our share-based payments for the nine months ended June 30, 2006 was $613,688. Cost of revenues, selling, general and administrative expense, and research and development expense for nine months ended June 30, 2006 include share-based compensation of $51,790, $183,383, $314,983 and $63,532, respectively. As of June 30, 2006, $3 million of total unrecognized compensation costs related to nonvested awards is expected to be recognized over a weighted average period of 3.7 years. See Note 10, “Stock-Based Compensation” in the Notes to Condensed Consolidated Financial Statements (unaudited) for further discussion.

Loss from Operations

Loss from operations was $5,800,044 for the nine months ended June 30, 2006 compared to a loss from operations of $6,503,805 for the nine months ended June 30, 2005. The decrease in loss from operations resulted primarily from the decrease in research and development expenses, partially offset by the decrease in gross profit.

Other Income (Expense)

During the nine months ended June 30, 2006, we earned $189,002 of interest income on our cash balances and incurred $1,101 of interest expense. Other income for the nine months ended June 30, 2006 included $1,362,000 related to the increase in the fair value of warrants issued in connection with our July 2005 sale of common stock and warrants.

At June 30, 2006 our long term derivative warrant instrument was $484,000. We must make certain assumptions and estimates to value our derivative warrant instrument periodically. Factors affecting the amount of this liability include changes in our stock price and other assumptions. The change in value is non-cash income or expense and the changes in the carrying value of derivatives can have a material impact on our consolidated financial statements each period. The derivative liability associated with our July 2005 sale of common stock and warrants may be reclassified into stockholders’ equity upon warrant exercise, expiration or other events, and the timing of such events may be outside our control.

During the nine months ended June 30, 2005, we earned $46,035 of interest on our cash balances and incurred $274,865 of interest expense and $183,259 of unrealized gain on derivative revaluation offset by $183,259 for the corresponding warrant impairment expense.

Net Loss

Net loss for the nine months ended June 30, 2006 decreased nearly 37% to $4,250,143, from a net loss of $6,732,635 for the nine months ended June 30, 2005. We had no income tax expense for either of these periods.

Net Loss Available to Common Stockholders

Net loss available to common stockholders decreased nearly 50% to $4,250,143, or $0.17, per share for the nine months ended June 30, 2006, compared to a net loss available to common stockholders of $8,529,061, or $0.41, per share for the nine months ended June 30, 2005. Imputed deemed dividends and accretion on outstanding preferred stock aggregated $1,796,426 for the nine months ended June 30, 2005. No preferred stock was outstanding during the three and nine months ended June 30, 2006.

Liquidity and Capital Resources

We continue to experience significant negative cash flow from operating activities including developing, introducing and marketing our proprietary sound technologies. We have financed our working capital requirements through cash generated from products sales and from financing activities. Cash at June 30,December 31, 2006 was $3,585,353$8,567,262 compared to $10,347,779$9,896,342 at September 30, 2005.2006. The decrease in cash was primarily the result of the operating loss, warranty costs previously accrued, increases in inventory, and cash used to support other activities. In August 2006 we completed an institutional financing providing gross proceeds of approximately $9.5 million. After paying financing and closing costs estimated at $570,000, we expect to use the net proceeds for general working capital.decreases in current liabilities.

Other than cash at June 30, the cash subsequently raised through the August 2006 financing and our balance of accounts receivable, we have no other unused sources of liquidity at this time. We expect to incur additional operating losses as a result of expenditures for research and development, marketing and sales costs and general and administrative costs for our sound products and technologies. The timing and amounts of these expenditures and the extent of our operating losses will depend on many factors, some of which are beyond our control.

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

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

Based on our current cash position cash received fromand our recent equity financing (see Note 18), our orderproduct backlog, and assuming currently planned expenditures and current level of operations, we believe we have sufficient capital to fundcash for operations for the next twelve months. We believe increased sales of LRAD, HSS and NeoPlanar products will continue to contribute cash in fiscal year 2007.

Cash Flows

Operating Activities

Our net cash used in operating activities was $6,769,094$1,352,771 for the ninethree months ended June 30,December 31, 2006 compared to $5,455,018$3,204,530 for the ninethree months ended June 30,December 31, 2005.

Cash used in operating activities for the nine months ended June 30, 2005 included the net loss of $6,732,635, reduced by expenses not requiring the use of cash of $893,550, a $1,058,310 increase in accounts payable and accrued liabilities; and a $246,282 decrease in trade accounts receivable and prepaid expenses, and increased by a $920,525 increase$1,078,969 decrease in inventories.accounts payable and accrued expenses.

At June 30,December 31, 2006, we had working capital of $5,440,844$12,440,413, compared to working capital of $9,726,309$12,658,863 at September 30, 2005.2006. This decrease was primarily a result of cash used for operations.in operating activities.

At June 30,December 31, 2006, we had trade accounts receivable of $2,676,384.$2,046,917. This compares to $880,276$2,055,132 in trade accounts receivable at September 30, 2005.2006. The level of trade accounts receivable at June 30,December 31, 2006 represented approximately 12148 days of revenues compared to 3284 days of revenues at September 30, 2005.2006. The increasedecrease in days was due to increased shipments of products in the last 10 days ofscheduled evenly throughout the quarter. Terms with individual customers vary greatly. We typically require thirty-day terms from our customers. Our receivables can vary dramaticallysignificantly 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 and software and investment in new patents. Cash used in investing activities for equipment was $357,516$18,909 and $19,399 for the ninethree months ended June 30, 2006. Cash used in investing activities for equipment was $448,535 for the nine months ended June 30, 2005.December 31, 2006 and 2005, respectively.

We anticipate continued capital expenditures for patents in fiscal year 2006. Cash used in investing activities of $58,265 for the nine months ended June 30, 2006, consisted of a security deposit for our current facilities.2007.

Financing Activities

Cash provided by financing activities for the ninethree months ended June 30, 2006December 31, 2005 was $600,917,$42,600, which included $610,940consisted of net cash proceeds from the exercise of stock options. Cash provided by financing activities for the ninethree months ended June 30,December 31, 2005 was $4,281,755 and consisted primarily of $1,979,023 in proceeds from the sale of unsecured promissory notes, $1,661,277 from exercise of common stock warrants and $649,577$61,032, which included $64,940 of net cash proceeds from the exercise of stock options.

August 2006 Equity Financing

In August 2006, we sold 4,870,512 shares of common stock at a purchase price of $1.95 per share. We also issued warrants to the investors to purchase 1,948,205 shares of common stock at an exercise price of $2.67 per share. The warrants are exercisable from February 7, 2007 until August 6, 2010.

The gross proceeds from this financing were approximately $9.5 million. We incurred financing and closing costs of approximately $570,000. We will use net proceeds for working capital purposes. We entered into a registration rights agreement with the investors, and agreed to prepare and file, within 30 days following the issuance of the securities, a registration statement covering the resale of the shares of common stock sold and the common stock issuable upon the exercise of the warrants. Failure to have an effective registration statement within 90 days obligates us to pay liquidated damages to the purchasers in the amount of 0.0165% of the gross proceeds per day until 180 days after the closing and 0.033% of the gross proceeds per day thereafter, but not to exceed a total of 20% of the purchase price paid by each investor.

We also agreed to submit the financing to a vote of our stockholders for approval prior to June 2007. We further agreed that, subject to certain exceptions, if during the period until one year following effectiveness of the registration statement we sell shares of our common stock, or options or warrants to purchase shares of its common stock, in a private placement or in a public offering using a Form S-3, the purchasers will have certain rights of first refusal to participate in the financing. We have also agreed to indemnify the purchasers for certain losses.

The warrants contain provisions that would adjust the exercise price, and in inverse proportion adjust the number of shares subject to the warrant, in the event we pay or effect stock dividends or splits, or in the event we sells share of our common stock at a purchase price, or options or warrants to purchase shares of our common stock having an exercise price, less than the exercise price of the applicable warrant. The warrants also feature a net exercise provision, which enables the holder to choose to exercise the warrant without paying cash by surrendering shares subject to the warrant with a market value equal to the exercise price. This right is available only if a registration statement covering the shares subject to the warrants is not available after it is initially declared effective.

Recent Accounting Pronouncements

A number of new pronouncements have been issued for future implementation as discussed in the Notesfootnotes to our Interim Consolidated Financial Statementsinterim financial statements (see Note 3)3 to interim consolidated financial statements).

Item 3. Quantitative and Qualitative Disclosures about Market Risk.

Market risk represents the risk of loss that may impact our financial position, results of operations or cash flows due to adverse changes in market prices, including interest rate risk and other relevant market rate or price risks. We do not use derivative financial instruments in our investment portfolio.

We are exposed to some market risk through interest rates, related to our investment of current cash and cash equivalents of approximately $3.6$8.6 million at June 30,December 31, 2006. Based on this balance, a change of one percent in interest rate would cause a change in interest income of $35,853.$85,672. The risk is not considered material and we manage such risk by continuing to evaluate the best investment rates available for short-term high quality investments.

Item 4. Controls and Procedures.

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 specified in the SEC rules and forms.

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our co-principalprincipal executive officers and principal financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended.1934. Based on this evaluation, our co-principalprincipal executive officers and our principal financial officer concluded that our disclosure controls and procedures were not effective as of June 30,December 31, 2006 due to the material weaknesses in internal control over financial reporting identified in the section “Management’s Report on Internal Control over Financial Reporting” set forth in our Annual Report on Form 10-K for the fiscal year ended September 30, 2006, many of which were ongoing at June 30, 2006 and an additional material weakness identified in the fiscal third quarter ended June 30,December 31, 2006.

A material weakness is defined in Public Company Accounting Oversight Board Standard No. 2 as a significant deficiency, or combination of significant deficiencies, that results in there being more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected.

The material weaknesses in internal control identified as a result of our fiscal year 20052006 integrated audit included the following:

Inventory Valuation

We did not maintain sufficient oversight and supervision of financially significant processes and systems, andIn December 2005, we noted deficiencies relating to monitoring and oversight of the work performed by our operations and accounting personnel. This material weakness was due primarily to a lack of adequate finance department supervision over finance and accounting personnel and a lack of human resources and insufficiently skilled personnel within our operations and accounting reporting functions. This material weakness resulted in errors in the preparation and review of financial statements, disclosures, schedules and reconciliations supporting certain general ledger account balances, errors not detected in certain accrued liability accounts and accounts payable, proper valuation and costing of inventory, proper tracking and accounting for fixed assets, and accurate valuation of accounts receivables, thereby resulting in audit adjustments to our fiscal year 2005 annual financial statements.

We did not maintain adequate processes for gathering key financial information to support the achievement of financial reporting objectives. As a result, management’s ability to monitor both internal and external events was compromised. This material weakness resulted from a lack of skilled personnel and adequate supervisory management, primarily in our finance and operations organizations. This material weakness resulted in the unavailability of reliable information concerning inventory, fixed assets, accounts receivable and accounts payable, which in turn contributed to audit adjustments to our fiscal year 2005 annual financial statements.

We did not maintain adequate processes to determine whether internal control over financial reporting was operating effectively and whether financial reports were reliably and accurately prepared. In particular, we lacked an ongoing monitoring processdetermined that would have enabled management to determine whether internal control over financial reporting was present and functioning. This material weakness resulted from a lack of skilled personnel and adequate supervisory management, primarily in our finance and operations organizations. This material

weakness resulted in various deficiencies in our financial reporting process relating to our inventory valuation, fixed asset accounting, accounts receivable and accounts payable, and resulted in audit adjustments for our fiscal year 2005 annual financial statements.

Controlscontrols that we havehad established for inventory valuation were not properly applied in connection with our financial statement closing process for the year ended September 30, 2005. This failure to apply existing controls relative to inventory valuation resulted both from lack of experienced accounting and operations personnel, the lack of proper supervision of such personnel, and the unexpected departure of personnel responsible for the application of such controls. This material weakness resulted in incorrect valuation and proper pricing of our inventory at our fiscal year ended September 30, 2005, thereby resulting in an audit adjustment to our fiscal year 2005 annual financial statements.

We did not maintain effective control over the accounting for fixed assets. We lacked an appropriate policy for reconciling certain recorded assets for which there was incomplete identifying information with assets on hand, and also lacked experiencedhired new accounting personnel responsiblein November and December 2005, and in the first and second quarters of 2006, we documented closing procedures for maintaining fixed assets. This material weakness resultedthese personnel to follow in an adjustmentproperly computing the cost of inventory on a net realizable basis. A full inventory count was performed at the end of each of the first three quarters of fiscal 2006 to ensure that we accounted for all inventory and an inventory revaluation was performed at December 31, 2005 and at June 30, 2006 to revalue inventory in accordance with our policies. At June 30, 2006 we modified our inventory module in our accounting system to value of the company’s fully depreciated fixed assets for which there was no impact to the company’s reported fixed assets net of depreciation, as well as an adjustment to the valuation of net fixed assetsall inventory transactions at FIFO rather than on a standard cost basis and at September 30, 2005.2006 we agreed the pricing of all items to supporting purchase invoices and other appropriate documentation. However, controls that we have established for inventory valuation were not properly applied in connection with our financial statement closing process for the quarters ended March 31 and June 30, and resulted in adjustments to our financial statements discovered during the reviews of those quarters by our independent registered public accounting firm. In the fourth quarter of 2006, we undertook and completed, as appropriate, our testing to validate compliance with the newly implemented policies, procedures and controls. In reviewing the results from this testing, management concluded that the internal controls over Inventory Valuation had been significantly improved. However, at September 30, 2006 there had not been sufficient time to fully evaluate these remediation efforts, and accordingly, there remained a risk that the remedial measures we had implemented would not cure the material weakness identified.

Stock Option Accounting

We didAs further described in the Explanatory Note to our fiscal 2006 Annual Report on Form 10-K and in Note 1 to the consolidated financial statements included in such report, management and our Audit Committee determined on December 15, 2006 that as a result of errors in the determination of measurement dates for a number of stock options granted prior to December 31, 2003, we would restate our previously issued financial statements for fiscal years ended September 30, 2005, 2004 and 2003, including 2002 and 2001 data, and that accordingly, our financial statements and the related reports of Swenson Advisors, LLP and BDO Seidman, LLP, and all related earnings press releases and communications relating to fiscal years 2005, 2004 and 2003, including 2002 and 2001 data, the quarterly reports on Form 10-Q filed with respect to each of these fiscal years and the financial statements included in the our quarterly reports on Form 10-Q for the interim periods of fiscal year 2006, should not maintain effective control overbe relied upon.

On July 28, 2006, the Public Company Accounting Oversight Board issued Staff Audit Practice Alert No. 1—Matters Related to Timing and Accounting for Option Grants, directing registered public accounting firms to perform additional review procedures related to their audit clients’ stock option granting practices. On September 19, 2006, the Office of the Chief Accountant of the SEC issued a letter to industry describing that office’s views on historical stock option accounting issues. In anticipation of the further audit procedures to be performed by our independent registered public accounting firm, our human resources and finance staff initiated in September 2006 a voluntary review of stock options granted during fiscal years 2002 to 2006. Following submission of our financial statements to our independent registered public accounting firm in November 2006 the Audit Committee engaged our outside counsel to perform further confirming procedures in November and December 2006. The information reviewed by outside counsel and evaluated using the standards articulated in the Office of the Chief Accountant’s letter indicated that measurement dates for accounts receivable. This failureaccounting purposes might differ from recorded dates used for certain grants made from fiscal 1998 to apply existing controls relativefiscal 2004.

In light of these events, the Audit Committee expanded the scope of review to cover the nine fiscal years ending September 30, 2006—reviewing all options granted since October 1, 1997, and also expanded its review to include the timing and documentary support for exercises of stock options, and the grants of a limited number of stock awards. The review was conducted with the continuing assistance of outside counsel, and with outside accounting consultants.

The Audit Committee determined that there existed flaws in our option approval and pricing processes, particularly relating to management’s practices during fiscal 2002 and 2003 of awarding grants prior to soliciting the approval of the Compensation Committee, and the related use of unanimous written consents to approve grants with a date “as of” the date management determined to grant the options, which consents were sometimes circulated after the date of determination, with signatures received back in the days following circulation. In some cases, the company lacks copies of counterpart signatures on unanimous written consents. In certain cases, unanimous written consents were obtained from the Compensation Committee for accounts receivables resulted fromgrants outside of shareholder approved plans, where the compensation committee had not been delegated authority by the Board to make such grants. For a large number of grants made between October 1997 and December 2003, we determined the exercise price based on the reported closing price on the date of grant, rather than the day prior to grant as required under the 1997 Stock Option Plan and the 2002 Stock Option Plan. While the Audit Committee found evidence of a lack of experienced accounting personnelformal process and inadequate supervisionrigor in documenting the exercise dates of stock options, the Audit Committee found no evidence that exercise dates were manipulated to reduce the taxes owed by option holders, or otherwise to confer improper benefits on option holders.

We determined that this series of events reflected that two material weaknesses in our internal control over financial reporting existed as of September 30, 2006. Specifically, as a result of the personnel responsible for timely accounts receivables reconciliations. We discovered several discrepancies between our accounting records and thosevoluntary review of our customers concerning the value of accounts receivable outstanding at September 30, 2005. This material weakness resulted in audit adjustments to our fiscal 2005 annual financial statements.

Wehistorical stock option grants, management determined that we did not maintain effective controls over the completeness and accuracy of our accounts payableaccounting for and recorded liabilities atmonitoring of our non-cash stock-based compensation expense and related financial statement disclosures, including our recording of various stock option transactions. This control deficiency resulted in management’s failure to detect errors with regard to the accounting for certain stock option grants and resulted in the restatement of our consolidated financial statements and related disclosures, as described above. Additionally, this control deficiency could result in a misstatement of non-cash stock-based compensation expense, additional paid-in capital, accumulated deficit and deferred compensation and financial statement disclosures related to stock options that could result in a material misstatement of the interim or annual consolidated financial statements that would not be prevented or detected. Accordingly, we have determined that this control deficiency constitutes a material weakness. We also determined that, as of September 30, 2005. Specifically,2006, we did not account for all invoices that had been issued to us by various vendors formaintain effective controls over the period ended September 30, 2005. This material weakness resulted in audit adjustments to our fiscal year 2005 annual financial statements.

An additional material weakness was discovered in the fiscal third quarter ending June 30, 2006.

We did not maintain adequate accounting processes to determine whether externally prepared financial information by contracted third parties for incorporation into our financial reporting was reliable and accurately prepared. This material weakness resulted from a lack of internal review and approval process and sufficient accounting personnel to staff for adequate review of the materials. This material weakness could have significantly impacted theincome tax provision calculation and related financial results for the quarter and potentially resulted in material adjustments to our current fiscal year 2006 annual financial statements.statement disclosures.

Our management has discussed the material weaknesses described above with our audit committee.Audit Committee. In an effort to remediate the identified material weaknesses and other control deficiencies, we have implemented or plan to implement the measures described below. Management has performed additional analyses and reviews for the ninethree months ended June 30,December 31, 2006 to help ensure that the consolidated financial statements and other financial information included in this report, fairly present in all material respects the financial condition, results of operations and cash flows of our company as of, and for, the periods presented in this report.

Remediation of Material Weaknesses

As of the filing date of this report, we have not fully remediated the material weaknesses in our internal control over financial reporting identified above. Management has taken a number of steps beginning in November 2005 that it believes will improve the effectiveness of our disclosure controls and procedures including the following:

Inventory Valuation

As discussed above, in Novemberprocedures, with appropriate controls, were developed, documented and December 2005, we hired new accounting department personnel who we believe haveimplemented during 2006 for all of the expertiserelevant processes that are critical to our quarterly and experience requiredannual reporting requirements.

Detailed checklists were developed to perform the functions to timely and correctly report financial results. In December 2005, we promoted Karen Jordan, who joined us in November 2005 as Director of Finance, to Chief Accounting Officer. In December 2005, our Chief Financial Officer resigned from his employment, and Mr. John R. Zavoli, our President and Chief Operating Officer, was appointed Interim Chief Financial Officer. In April 2006, Mr. Steven D. Stringer assumed the position of Chief Financial Officer, and in such position is providing with Ms. Jordan close supervision of accounting personnel to ensure compliance with our controls and procedures. Prior to April 2006, close supervision was provided by Mr. Zavoli and Ms. Jordan. Reconciliations are reviewed consistently, and all journal entries and reconciliations are reviewed and signed by the Chief Accounting Officer. During the third quarter ending June 30, 2006 an additional weakness identified inenhance the financial reportingclose process indicate that additional testing and further controls are necessary.inventory valuation functions.

We have hired new accounting and operations personnel, including new management personnel. In December 2005, we designed a procedure for our accounting department to disseminate key information and metrics to senior management beginning in our second quarter of fiscal 2006 in order to support the achievement of financial reporting objectives. In addition, significant financial reporting and cost reporting was implemented in the third quarter to report the financial details and margin analysis for the Company. We believe that these steps will correct the associated material weakness discussed above, but we will need to perform additional testing in order to reach a conclusion that the weakness has been corrected, and further controls may be necessary.

We have hired new accounting personnel including new management personnel. In December 2005, these personnel were directed to review our monitoring controls, and to the extent necessary, improve monitoring processes to be consistent with the criteria based on the COSO Framework. We believe that these steps will correct the associated material weakness discussed above, but we will need to perform additional testing in order to reach a conclusion that the weakness has been corrected

We have hired new accounting personnel and have documented closing procedures that these personnel will follow in properly computing the cost of inventory on a net realizable basis. A full inventory count was performed at the end of each quarter of fiscal 2006 and at the end of the first three quartersquarter ended December 31, 2006, to ensure that we accounted for all inventory. At June 30, 2006 we modified our inventory module in our accounting system to value all inventory transactions at FIFO rather than on a standard cost basis and an inventory revaluationat September 30, 2006 and December 31, 2006 we agreed the pricing of all items to supporting purchase invoices and other appropriate documentation.

In the fourth quarter of 2006 and the first quarter of 2007, we undertook and completed, as appropriate, our testing to validate compliance with the newly implemented policies, procedures and controls. In reviewing the results from this testing, management has concluded that the internal controls over Inventory Valuation were functioning adequately for the quarter ended December 31, 2006.

Completeness and Accuracy of Accounting for and Monitoring Stock-Based Compensation Expense and Related Financial Statement Disclosure

The voluntary review of our historical stock option and stock grants was performedongoing at December 31, 20052006, and was concluded in early January 2007. We believe the completion of that review and the resulting restatement of historical financial statements has remediated the material weakness concerning the completeness and accuracy of accounting for and monitoring stock-based compensation expense and related financial statement disclosure. In addition, in January 2007, our Compensation Committee adopted revised stock option grant and exercise procedures, and we modified our internal controls over equity transactions to conform to these new procedures. These new procedures include:

Preparation, Analysis, Documentation, and Review of the Income Tax Provision Calculation

Management is currently reviewing our controlscontrol policies and procedures relatedwith respect to incurring liabilities, including purchasing procedurespreparation, analysis, documentation, and properly identifying and recording accounts payable. We believe these steps will correctreview of the associated material weakness discussed above; but we will need to perform additional testing in order to reach a conclusion that the weakness has been corrected and further controls may be necessary.

There can be no assurance that we will be successful in remediating the above-mentioned material weaknesses in our internal control.income tax provision calculation.

Changes in Internal Control over Financial Reporting

Except as discussed above, there were no changes in our internal control over financial reporting during our fiscal quarter ended June 30,December 31, 2006 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
