PART I

Item 1. Business

We were incorporated in 1969 in Pennsylvania and are principally engaged in the design, manufacture and sale of software driven products used to create and monitor the physiological effects of motion on humans and equipment and to control, modify, simulate and measure environmental conditions. These products include aircrew training systems, entertainment products, sterilizers, environmental and hyperbaric chambers and other products that involve similar manufacturing techniques and engineering technologies.

Segments

We operate in two primary business segments, Aircrew Training Systems (ATS) and the Industrial Group.

Aircrew Training Systems. This segment includes three primary product groups: aircrew training devices, entertainment products and disaster management simulation.

Aircrew Training Devices. Our aircrew training devices are used for medical research, advanced tactical and physiological flight training, and for the indoctrination and testing of military and commercial pilots. The major devices that we sell in this business segment are military and commercial flight simulators, night vision trainers, water survival training equipment, disorientation training equipment, human centrifuges, ejection seat trainers and vehicle and tank simulators. We provide operational and maintenance services for installed equipment that we manufacture as well as for equipment produced by others.

Entertainment Products. Our entertainment products consist of motion-based simulation rides and other products for the education and amusement industries.

Disaster Management Simulation. Our Disaster Management Simulation line includes real-time interactive training programs that provide instruction on various disaster situations.

The Aircrew Training System segment generated 60%, 60% and 61% of our consolidated revenues for the fiscal years ended February 24, 2006, February 25, 2005 and February 27, 2004, respectively.

Industrial Group. This segment includes three primary product lines: sterilizers, environmental systems and other products, and hyperbarics.

Sterilizers. We manufacture steam and gas sterilizers for various industrial and pharmaceutical applications. We concentrate on marketing larger custom-designed sterilizers to the pharmaceutical and medical device industries.

Environmental Systems and Other Products. Our environmental systems business consists of the design and fabrication of sampling and analysis systems, and test equipment and systems. The simulation systems generally consist of an enclosed chamber with instrumentation and equipment which enable the customer to control and modify environmental factors such as temperature, pressure, humidity, wind velocity and gas content to produce desired conditions. These products include controlled air systems for automotive companies and environmental chambers for HVAC and other applications.

Hyperbarics. Our hyperbarics product line includes monoplace (single person) and multiplace (multiple persons) chambers for high altitude training, decompression and wound care applications.

Sales of Industrial Group products generated 40%, 40% and 39% of our consolidated revenues for the years ended February 24, 2006, February 25, 2005 and February 27, 2004, respectively.

We also provide control upgrades, maintenance and repair services and spare parts for equipment which we manufacture and for equipment made by other manufacturers.

For a more complete description of financial information regarding our business segments, see Note 10, Business Segment Information to our consolidated financial statements in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference.

Marketing

We currently market our products and services primarily through our sales offices and employees. At February 24, 2006, approximately 22 employees were committed to sales and marketing functions. We use branch offices in England, Turkey, Egypt, Singapore, the United Arab Emirates, Malaysia and Japan as well as the services of approximately 100 independent sales organizations in seeking foreign orders for our products.

Product Development

We are continually developing new products and improving existing products in response to inquiries from customers and in response to our determination that particular products should be produced or significantly improved. Although we do not have a separate research and development group, we have several technical personnel whose main activity is the development and integration of new technologies into our existing products. These personnel include the Vice President Engineering Manager and the Vice President of Development whose additional responsibility is the introduction of product extensions and new applications of existing technology.

Within the Aircrew Training Systems segment, product development emphasizes enhancing control systems and software graphics and exploring commercial possibilities. Our product development efforts focus on three areas:

Disaster Management Simulation. During fiscal 2006, our simulation line continued to expand its influence in the disaster management arena by contracting multiple training exercises for Baltimore/Washington International Airport (BWI) covering several different areas of airport disaster response including a security breach, a terrorism-related hazardous materials (HAZMAT) incident and airplane crash landings. They also constructed an Advanced Disaster Management Simulator ADMS-Drive Airport Ground Vehicle Driving Simulator for the Metropolitan Nashville Airport Authority. Locally, the line signed a contract with the Pennsylvania Southeast Region Counter-Terrorism Task Force (CTTF) to provide an ADMS-TEAM training system. In December 2005, the Netherlands National Institute for Fire Services and Disaster Management (NIBRA) passed its 10,000
thstudent through the ADMS training course originally developed and installed by ETC. Earlier this year, our next generation 20-station ADMS System passed initial acceptance by the South Korean National Fire Academy. ADMS has also been successfully utilized to conduct training exercises at the National War College in Washington, DC, and the Port of Jacksonville, Florida.

We will continue to enhance product applications by adding additional software objects and increasing interactivity between the various disaster scenarios.

G-force and Disorientation Trainers.

During fiscal 2006, our ATFS400 flight training centrifuge was accepted by the Royal Malaysian Air Force at a ceremony at the new Subang Air Base training facility close to Kuala Lumpur. This device was used by Malaysia to select the first Malaysian cosmonauts, one of which will be chosen to serve as a crewmember on the International Space Station in October 2007. We also began final assembly on our second ATFS-400 which will be used to support research and pilot and space flight training. Proprietary centrifuge and simulation technology, high-fidelity models of the airplanes dynamic performance, the threats experienced by an aircraft in combat and other battle space factors are integrated into the motion controls to create a fully authentic flight environment for any specific combat aircraft.

We were able to expand the functionality of our Gyrolab line as we received significant orders from the Japanese Defense Agency for a GL-4000 and from a Middle Eastern customer for a GL-1500.

We plan to incorporate additional advanced tactical flight simulation (TFS) applications into additional products in the ATS line.

NASTAR

In fiscal 2006, we began construction of the National AeroSpace Training and Research Center (NASTAR Center). This center, set to open in January 2007, will offer a complete range of aviation training and research support for military and civil aviation as well as space travel and tourism. The NASTAR Center will house state of the art equipment including the ATFS-400, GYROLAB GL-2000 Advanced Spatial Disorientation Trainer, Hypobaric Chamber and Night Vision and Night Vision Goggle Training System. These products represent 37 years of pioneering development and training solutions for the most rigorous stresses encountered during high performance aircraft flight including the effects of altitude exposure, High G exposure, spatial disorientation and escape from a disabled aircraft.

We reported research and development expenses of $422,000, $856,000 and $358,000 for the fiscal years ended February 24, 2006, February 25, 2005 and February 27, 2004, respectively. However, most of the cost of our research efforts, which were and continue to be a significant cost of our business, are included in cost of sales for applied research for specific contracts, as well as research for feasibility and technology updates.

Subsidiaries

We
    presently have four operating subsidiaries. Entertainment Technology Corporation,
    our wholly-owned subsidiary, is a Pennsylvania corporation that focuses on
    the development, manufacturing and distribution of our entertainment products.
    ETC-PZL Aerospace Industries, our 95%-owned subsidiary, is a Polish corporation
    that manufactures simulators. ETC-Europe, our 99%-owned subsidiary, is a
    United Kingdom corporation that focuses on generating international sales.
    NASTAR Center LLC is our wholly-owned subsidiary which houses our NASTAR
    Center and all its activities. ETC-Delaware, our wholly-owned subsidiary,
    is a Delaware corporation that
serves as a holding company.

Suppliers

The components being used in the assembly of systems and the parts used to manufacture our products are purchased from equipment manufacturers, electronics supply firms and others. Historically, we have had no difficulty in obtaining supplies. Further, all raw materials, parts, components and other supplies which we use to manufacture our products can be obtained at competitive prices from alternate sources should existing sources of supply become unavailable.

Customers

In the current fiscal year and throughout most of our history, we have made a substantial portion of our sales to a small number of customers that vary within any given fiscal year. We do not depend upon repeat orders from these same customers. We sell our aircrew training systems principally to U.S. and foreign governmental agencies. We sell sterilizers and environmental systems to commercial and governmental entities worldwide.

In fiscal 2006 two customers represented 10% or more of sales, L-3 Communications and the Pakistan Air Force, which togethergenerated $7,509,000 or 30%of total sales. We do not have any relationship with these customers other than as customers. We expect to continue to conduct business with both of these customers in fiscal 2007, albeit at a much reduced level.

Foreign and Domestic Operations and Export Sales

During the fiscal years ended February 24, 2006, February 25, 2005 and February 27, 2004, approximately $2,586,000 (10%), $2,904,000 (10%) and $1,717,000 (7%), respectively, of our net revenues were attributable to contracts with agencies of the U.S. Government or with other customers who had prime contracts with agencies of the U.S. Government.

During the fiscal years ended February 24, 2006, February 25, 2005 and February 27, 2004, $13,343,000 (53%), $12,912,000 (47%) and $15,421,000 (59%), respectively, of our net revenues were attributable to export sales, including those in our foreign subsidiaries. Our customers obligations to us with regards to export sales are normally secured by irrevocable letters of credit based on the creditworthiness of the customer and the geographic area of the world in which they are located.

During the fiscal years ended February 24, 2006, February 25, 2005 and February 27, 2004, $9,140,000 (37%), $11,998,000 (43%) and $8,857,000 (34%), respectively, of our net revenues were attributable to domestic sales to customers other than the U.S. government. (See Note 10. Business Segment Information to our consolidated financial statements in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference).

We do not believe that the distribution of our sales between foreign and domestic sales for any particular period is necessarily indicative of the distribution expected for any other period.

We derive a large portion of our sales from long-term contracts requiring more than one year to complete. We account for sales under long-term contracts on the percentage of completion basis. See the section Critical Accounting Policies in the Managements Discussion and Analysis of Financial Condition and Results of Operations and Note 2. Summary of Significant Accounting Policies to our consolidated financial statements in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference.

Our U.S. Government contracts contain standard terms permitting termination for the convenience of the U.S. Government. In the event of termination of a government contract, we are entitled to receive reimbursement on the basis of work completed (cost incurred plus a reasonable profit). We customarily record the amounts that we anticipate to be recovered from termination claims in income as soon as those amounts can be reasonably determined rather than at the time of final settlement. All costs applicable to a termination claim are charged as an offsetting expense concurrently with the recognition of income from the claim.

Manufacturing Facilities

Our manufacturing facility is located on a five-acre site in Southampton, PA, northwest of Philadelphia. We have approximately 85,000 square feet devoted to manufacturing, assembly and testing. We have two centrifuge bays with specially designed foundations for testing human centrifuges and other centrifuge-technology-based simulators and amusement rides. ETC is ISO 9001-2000 certified.

Backlog

Our sales backlog at February 24, 2006 and February 25, 2005, for work to be performed and revenue to be recognized under written agreements after such dates, was $8,132,000 and $19,084,000 respectively. In addition, our training, maintenance and upgrade contracts backlog at February 24, 2006 and February 25, 2005, for work to be performed and revenue to be recognized after such dates under written agreements, was $1,774,000 and $2,232,000, respectively. Of the February 24, 2006 backlog, we have contracts for approximately $5,371,000 for aircrew training systems and maintenance support, including $2,243,000 for the JapaneseDefense Agency, $975,000 for the Pakistan Air Force, and $798,000 for Singapore. We expect to complete approximately 94% of the February 24, 2006 backlog prior to February 23, 2007, the end of our 2007 fiscal year. Of the
February 25, 2005 backlog, we completed approximately 82% by February 24, 2006.

The decrease in bookings and resulting backlog reflects the difficult world conditions for the Companys products, especially in the ATS line.

Competition

Our business strategy in recent years has been to seek niche markets in which there is limited competition. However, in some areas of our business we compete with well-established firms, some of which have substantially greater financial and personnel resources than we have.

Some competing firms have technical expertise and production capabilities in one or more of the areas involved in the design and production of physiological flight training equipment, environmental systems, and other specially designed products, and compete with us for this business. The competition for any particular project generally is determined by the technological requirements of the project, with consideration also being given to a bidders reliability, product performance, past performance and price.

We face competition in the sale of the larger custom-designed industrial sterilizers both from other manufacturers and from our customers in-house production capabilities.

We believe that we are a significant participant in the markets in which we compete, especially in the market for aircrew training systems where we believe that we are a principal provider of this type of equipment and training in our market area.

Compliance with Environmental Laws

We have not incurred during fiscal 2006, nor do we anticipate incurring during fiscal 2007, any material capital expenditures to maintain compliance with federal, state and local statutes, rules and regulations concerning the discharge of materials into the environment, nor do we anticipate that compliance with these provisions will have a material adverse effect on our earnings or competitive position.

Compliance with Export Controls

Depending on the product, customer, location and the application or use, many of our aeromedical products require an export license from the U.S. Commerce or State Department. Although most of these licenses are readily obtainable in a reasonable timeframe, most of our international contracts for aeromedical equipment include the issuance of an export license as a force majure exception for any contract penalties or liquidated damages.

Employees

On February 24, 2006, we had 223 full-time employees, of which four were employed in executive positions, 76 were engineers, engineering designers, or draftspeople, 52 were administrative (sales, sales support, accounting, etc.) and clerical personnel, and 91 were engaged principally in production, operations and field support.

Item 1A. Risk Factors

RISKS PARTICULAR TO OUR BUSINESS

Our business is subject to numerous risks and uncertainties which could cause our actual operating results and developments to be materially different from those expressed or implied in any of our public announcements or filings including this Annual Report on Form 10-K for the year ended February 24, 2006. These risks and uncertainties include the following items. This list is not inclusive of all the risks and uncertainties associated with our business.

We have major litigation and claims in process and these require a significant amount of management time and effort. Additionally, legal costs are a major portion of our general and administrative spending, thus redirecting funds from other operating activities.

Legal and claims costs in fiscal 2006 were $1.5 million or 16% of total general and administrative spending. It is expected that this spending level will increase in fiscal 2007 as open litigation nears the trial stage. Please see Item 3 (Legal Proceedings) for further information on our litigation.

There is a risk of an unfavorable outcome in litigation and resulting potential negative financial impact on our operating results.

In one of the cases of commercial litigation currently in progress, we have been counter-sued for an amount in excess of $65 million. While we believe we have valid defenses to each of the counterclaims and intend to vigorously defend ourselves against these counterclaims, an unfavorable outcome could result in an adverse material effect on our financial position. With respect to the claim against the U.S. government, recoveries have usually exceeded the carrying value of claims. However, these claims require significant management time and effort and normally take multiple years to resolve. Also, there is no assurance that we will always have positive experience with regard to recoveries for our contract claims, whether at the carrying values of the claims or amounts in excess of the carrying values of the claims.

Our sources of revenues are not consistent; in any given fiscal year a substantial portion of our revenues is derived from a small number of customers that may not be recurring customers in future years.

In any given fiscal year, a substantial portion of our revenues is typically derived from a small number of customers. For example, in fiscal 2006 we generated approximately30%of our revenues from sales to two customers, L-3 Communications andthe Pakistan Air Force. In fiscal 2005, we generated approximately 36% of our revenues from sales to four customers, the Royal Malaysian Air Force, the United Kingdom Ministry of Defense, the Army Corp of Engineers, and a domestic customer. In fiscal 2004, we generated approximately 22% of our revenues from sales to two customers, the Royal Malaysian Air Force and the United Kingdom Ministry of Defense. We cannot be certain that our most significant customers will continue to order our products and services at
the same level at which they have ordered them in the past. Due to the expensive nature and highly specialized market for our products and services, if any of these customers stops purchasing our products and services and we are unable to identify new customers in a timely manner, our business will be adversely affected.

Our significant debt could adversely affect our financial resources and prevent us from satisfying our debt service obligations.

We have a significant amount of indebtedness. Additionally, we will have to pay a 6% dividend payment on the $3,000,000 of preferred stock which we issued to Mr. Lenfest on April 7, 2006. We may also incur additional indebtedness in the future. We may not generate sufficient cash flow from operations, or have future borrowings available to us, sufficient to pay our debt. During fiscal 2006, we experienced a negative cash flow of $8.5 million. At May 12, 2006, our total indebtedness was approximately $16.1 million, we had $3,000,000 of outstanding preferred stock, and our total stockholders equity was approximately $17.6 million.

Our ability to make debt payments depends on future performance, which, to a certain extent, is subject to general economic, financial, competitive and other factors, some of which are beyond our control. Based upon our current level of operations and anticipated growth, we believe that cash on hand and borrowings under our equity line agreement with H.F. Lenfest will be adequate to meet our financial needs. There can be no assurance, however, that our business will generate sufficient cash flow from operations to enable us to pay our debts or to make necessary capital expenditures, or that any refinancing of debt would be available on commercially reasonable terms or at all.

Our substantial indebtedness could have important consequences including:

| |  | our ability to obtain additional financing for working capital, capital expenditures, acquisitions or other purposes may be impaired or unavailable;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------

| |  | a portion of cash flow will be used to pay interest expense, which will reduce the funds that would otherwise be available for operations and future business opportunities;
| | - | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | a substantial decrease in net operating cash flows or an increase in expenses could make it difficult for us to meet our debt service requirements and force us to reduce or modify our operations;
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | our significant debt may make us more leveraged than our competitors, which may place us at a competitive disadvantage;
| | - | -----------------------------------------------------------------------------------------------------------------------

| |  | our significant debt may make us more vulnerable to a downturn in our business or in the economy generally;
| | - | -----------------------------------------------------------------------------------------------------------

| |  | some of our existing debt contains financial and restrictive covenants that limit our ability to borrow additional funds, acquire and dispose of assets, and pay cash dividends; and
| | - | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | our subordinated debt bears a relatively high interest rate, reflecting the unsecured nature and correspondingly higher risk associated with this type of financing. This results in higher interest expense and use of cash.
| | - | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| |  | Although currently none of our debt bears interest at rates that vary with the prime rate of interest, it is expected that any additional debt which we might incur would carry a floating rate. If this were the case, any increases in the applicable prime rate of interest would reduce our earnings.
| | - | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

See the Liquidity and Capital Resources section of the Annual Report to Stockholders attached as Exhibit 13 to this Annual Report on Form 10-K.

We do not currently have a bank facility which can be used to borrow funds for operating purposes. Additionally, covenants and restrictions in our credit facility, and any additional changes in the facility amount or structure, could limit our ability to take certain actions and fund our operations.

On May 19, 2006 we signed an amendment to our bank agreement with PNC Bank, National Association extending the termination date to June 30, 2006. This $5,000,000 facility is restricted to use for issuing letters of credit. As of May 12, 2006, we had used approximately $2,900,000 million of this facility for international letters of credit. We may need to obtain additional sources of capital in order to continue growing and operating our business. This capital may be difficult to obtain and the cost of this additional capital is likely to be relatively high.

Our subordinated debt agreement with Mr. Lenfest contains significant financial and operating covenants that limit the discretion of our management with respect to certain business matters. These covenants include, among others, restrictions on our ability to:

| |  | declare or pay dividends or any other distributions to our securities holders;
| | - | ------------------------------------------------------------------------------

| |  | redeem or repurchase capital stock;
| | - | -----------------------------------

| |  | incur certain additional debt;
| | - | ------------------------------

| |  | place liens on our assets;
| | - | --------------------------

| |  | make certain payments and investments;
| | - | --------------------------------------

| |  | sell or otherwise dispose of assets; and
| | - | ----------------------------------------

| |  | acquire or be acquired by other entities.
| | - | -----------------------------------------

We must also meet certain financial ratios and tests under our agreement. If we do not comply with the obligations set forth in the agreement, it could result in an event of default, and possibly the acceleration of the related debt. Negative operating results would impact our future compliance with these covenants and could adversely affect our business.

Our liquidity and capitalization improved subsequent to fiscal year end when we signed an equity line agreement with H.F. Lenfest, a Director, significant shareholder and holder of our subordinated debt. Under certain conditions, we will have access to up to $15 million in cash to support operations. However, given our low beginning sales backlog and ongoing difficulty in obtaining new contracts, we may need to obtain additional sources of capital in order to continue growing and operating our business. Because we have established businesses in many markets, significant fixed assets including a building, and other business assets which can be used for security, we believe that we will be able to locate such additional sources of capital, although there is no assuredness that we will be successful in this endeavor.

See the Liquidity and Capital Resources section of the Annual Report to Stockholders attached as Exhibit 13 to this Annual Report on Form 10-K.

Our operations involve rapidly evolving products and technological change.

The rapid change of technology is a key feature of all of the industries in which our businesses operate. To succeed in the future, we will need to continue to design, develop, manufacture, assemble, test, market and support new products and enhancements on a timely and cost-effective basis. Historically, our technology has been developed through both customer-funded and internally funded research and development, and we expect this practice will continue to be required in the future. We cannot guarantee that we will continue to maintain comparable levels of research and development nor that this development will be customer-funded in the same ratio going forward. Reinvestment of operating funds and profits in an amount greater than currently earned may be required. Even so, we cannot assure you that we will successfully identify new opportunities and continue to have the financial
resources required to develop new products profitably. At the same time, products and technologies developed by others may render our products and systems obsolete or non-competitive.

Delays in the delivery of our products may prevent us from invoicing our costs and estimated earnings on uncompleted contracts.

In accordance with generally accepted accounting principles for long-term contracts, we record an asset for our costs and estimated earnings that exceed the amount we are able to bill our customers on uncompleted contracts. At February 24, 2006, $3.2 million or 93% of our costs and estimated earnings that exceeded our billings on uncompleted contracts related to contracts with two different customers. We are not able to bill these amounts unless we meet certain contractual milestones related to the production, delivery and integration of our products. Normally there will be a lag ranging from 24 to 36 months between performance and associated costs for these types of projects and billing and collection of payments. Our failure to meet these milestones by delivering and integrating our products in a timely manner may impact our ability to recover our costs and estimated earnings that
exceeded our billings on uncompleted contracts, which could severely impact our cash flow.

In the event we suffer production delays, we may be required to pay certain customers substantial liquidated damages and other penalties.

The variety and complexity of our high technology product lines require us to deal with suppliers and subcontractors supplying highly specialized parts, operating highly sophisticated equipment and performing highly technical calculations. The processes of planning and managing production, inventory levels and delivery schedules are also highly complex and specialized. Many of our products must be custom designed and manufactured, which is not only complicated and expensive, but can also require long periods of time to accomplish. Slight errors in design, planning and managing production, inventory levels, delivery schedules, or manufacturing can result in unsatisfactory products that may not be correctable. If we are unable to meet our delivery schedules, we may be subject to penalties, including liquidated damages that are included in some of our customer contracts. While our actual
losses have been minimal, we may incur substantial liquidated damages in the future in connection with product delays.

If the commercial simulation business conducted by our Aircrew Training Systems Segment declines, our sales will decrease.

We have no assurance that our commercial simulation business will continue to succeed. Although our commercial simulation business was minimal in fiscal 2006, this segment historically contributes to our gross revenues in each fiscal year. This business is subject to many risks including:

| |  | the uncertainty of economic conditions;
| | - | ---------------------------------------

| |  | increased competition;
| | - | ----------------------

| |  | changes in technology; and
| | - | --------------------------

| |  | the need for timely performance by subcontractors located throughout the world on contracts for which we are the prime contractor.
| | - | ----------------------------------------------------------------------------------------------------------------------------------

If we do not adequately address these risks, then our commercial simulation business may decline which will adversely affect our business.

Our fixed-price and cost-reimbursable contracts may commit us to unfavorable terms.

We provide our products and services primarily through fixed-price or cost-reimbursable contracts. Fixed-price contracts provided approximately 94% of our sales for the fiscal year ended February 24, 2006. Under a fixed-price contract, we agree to perform the scope of work required by the contract for a predetermined contract price. Although a fixed-price contract generally permits us to retain profits if the total actual contract costs are less than the estimated contract costs, we bear the risk that increased or unexpected costs may reduce our profit or cause us to sustain losses on the contract. Therefore, unless there are customer-requested changes in scope or other changes in specifications which are reimbursable, we fully absorb cost overruns on fixed-price contracts and this reduces our profit margin on the contract. These cost overruns may result in us recognizing a loss on the
contract. A further risk associated with fixed-price contracts is the difficulty of estimating sales and costs that are related to performance in accordance with contract specifications. Our failure to anticipate technical problems, estimate costs accurately or control costs during performance of a fixed-price contract may reduce our profitability or cause a loss.

We did not have any sales for cost-reimbursable contracts for the fiscal year ended February 24, 2006. On a cost-reimbursable contract, we are paid up to predetermined funding levels determined by our customers on allowable incurred costs and generally a fee representing a profit on those costs, which can be fixed or variable depending on the contracts pricing arrangement. Therefore, on a cost-reimbursable contract we do not bear the risks of unexpected cost overruns. U.S. Government regulations require that we notify our customer of any cost overruns or under runs on a cost-reimbursable contract on a timely basis. Should we be awarded any cost-reimbursable contracts in the future and incur costs in excess of the funding limitation specified in the cost-reimbursable contracts, we may not be able to recover those cost overruns.

Cost estimates used to account for contracts under the percentage of completion method may vary over time and impact future performance under these contracts.

We record sales and profits on a significant portion of our contracts using the percentage-of-completion method of accounting. This means that we calculate a ratio of costs incurred to costs expected to be incurred for each fixed-price job and then multiply that same ratio by the fixed-price contract value to determine total revenue to be recognized to date for each fixed-price job. As a result, contract price and cost estimates on fixed-price contracts are reviewed periodically as the work progresses, and adjustments are reflected in income in the period when the estimates are revised. To the extent that these adjustments result in a loss, reduction or elimination of previously reported profits, we would recognize a charge against current earnings, which could be material and have a negative effect on our business, financial condition or results of operations. Although we believe that
adequate provisions for losses for our fixed-prices contracts are recorded in our financial statements as required under accounting principles generally accepted in the United States of America, we cannot assure you that our contract loss provisions, which are based on estimates, will be adequate to cover all actual future losses.

Our contracts and subcontracts that are funded by the U.S. government or foreign governments are subject to government regulations and audits and other requirements.

Government contracts require compliance with various contract provisions and procurement regulations. The adoption of new or modified procurement regulations could have a material adverse effect on our business, financial condition or results of operations or increase the costs of competing for or performing government contracts. If we violate any of these regulations, then we may be subject to termination of these contracts, imposition of fines or exclusion from government contracting and government-approved subcontracting for some specific time period. In addition, our contract costs and revenues are subject to adjustment as a result of audits by government auditors. We reflect any adjustments required by government auditors in our financial statements. Although we have thus far not been required to make any material audit adjustments, adjustments may be required in the future. In
connection with our government contracts, we have been required to obtain bonds, letters of credit or similar credit enhancements. We cannot assure you that we will be successful in obtaining these types of credit enhancements or that the credit enhancements available will be affordable in the future.

Our contracts that are funded by the U.S. government or foreign governments are subject to a competitive bidding process that may affect our ability to win contract awards or renewals in the future.

Government contracts generally are awarded to us through a formal competitive bidding process in which we may have many competitors. Upon expiration, government contracts may be subject, once again, to the competitive bidding process. We cannot assure you that we will be successful in winning contract awards or renewals in the future. Our failure to renew or replace government contracts when they expire could have a material adverse effect on our business, financial condition or results of operations. Our contracts with domestic or foreign government agencies are subject to competition and are awarded on the basis of technical merit, personnel qualifications, experience and price. Our business, financial condition and results of operations could be materially adversely affected to the extent that government agencies believe our competitors offer a more attractive combination of the
foregoing factors. In addition, new government contract awards also are subject to protest by competitors at the time of award that can result in the re-opening of the competition or evaluation process, the award of a contract to a competitor, or the re-opening of the competitive bidding process. We consider bid protests to be a customary element in the process of procuring government contracts. Other characteristics of the government contract market that may affect our operating results include the complexity of designs, the difficulty of forecasting costs and schedules when bidding on developmental and highly sophisticated technical work, and the speed with which product lines become obsolete due to technological advances and other factors characteristic of the market. Our earnings may vary materially on some contracts depending upon the types of government long-term contracts undertaken, the costs incurred in their performance, and the achievement of other performance
objectives.

Our commercial contracts are subject to competition and strict performance and other requirements.

Although significant portions of our revenues are generated from the sale of our services and products in commercial markets, we cannot assure you that we will continue to compete successfully in these markets. Many of our commercial contracts contain fixed pricing. This subjects us to substantial risks relating to unexpected cost increases and other factors outside of our control. We may fail to anticipate technical problems, estimate costs accurately, or control costs during performance of a fixed-price contract. Any of these failures may reduce our profit or cause a loss under our commercial contracts. In addition, a significant portion of our revenues on fixed-price contracts (72% in fiscal 2006) is recognized on a percentage-of-completion basis. This means that we calculate a ratio of costs incurred to costs expected to be incurred for each fixed-price job and then multiply that same
ratio by the fixed-price contract value to determine total revenue to be recognized to date for each fixed-price job. As a result, contract price and cost estimates on fixed-price contracts are reviewed periodically as the work progresses, and adjustments are reflected in income in the period when the estimates are revised. To the extent that these adjustments result in a loss, reduction or elimination of previously reported profits, we would recognize a charge against current earnings, which could be material and have a negative effect on our business, financial condition or results of operations.

In connection with certain commercial contracts, we have been required to obtain bonds, letters of credit, or similar credit enhancements. We cannot assure you that we will be successful in obtaining these types of credit enhancements or that the credit enhancements available will be affordable in the future.

Under the terms of our commercial contracts, we typically must agree to meet strict performance obligations and project milestones, which we may not be able to satisfy. If we fail to meet these performance obligations and milestones, the other party may   terminate the contract and, under certain circumstances, recover liquidated damages or other penalties from us which could have a negative effect on our business, financial condition or results of operations.

There are certain risks inherent in our international business activities, which constitute a significant portion of our business.

Our international business activities expose us to a variety of risks. Our international business including that from our foreign subsidiaries, accounted for approximately 53% of our sales in fiscal 2006 and 47% of our sales in fiscal 2005. We expect that international sales will continue to be a significant portion of our overall business in the foreseeable future. Our international business experiences many of the same risks our domestic business encounters as well as additional risks such as:

| |  | the effects of terrorism;
| | - | -------------------------

| |  | exchange rate fluctuations;
| | - | ---------------------------

11

| |  | a longer and more complicated collections cycle;
| | - | ------------------------------------------------

| |  | a high degree of corruption in some countries;
| | - | ----------------------------------------------

| |  | a general decline in the strength of the global economy;
| | - | --------------------------------------------------------

| |  | the effect of foreign military or political conflicts and turmoil;
| | - | ------------------------------------------------------------------

| |  | U.S. foreign policy decisions;
| | - | ------------------------------

| |  | the extent, if any, of anti-American sentiment;
| | - | -----------------------------------------------

| |  | changes in foreign governmental trade, monetary and fiscal policies and laws;
| | - | -----------------------------------------------------------------------------

| |  | export controls; and
| | - | --------------------

| |  | political and economic instability.
| | - | -----------------------------------

The majority of our contracts are denominated in U.S. dollars. Although we may be exposed to currency fluctuations, we are not engaged in any material hedging activities to offset this risk. With respect to currency risk, where we have a contract which is denominated in a foreign currency, we often establish local in-country bank accounts and fund in-country expenses in the local currency, thus creating a natural currency hedge for a portion of the contract.

Our international transactions frequently involve increased financial and legal risks arising from stringent contractual terms and conditions and widely differing legal systems, customs and standards in foreign countries. In addition, our international sales often include sales to various foreign government armed forces, with many of the same inherent risks associated with U.S. government sales discussed in this Annual Report on Form 10-K.

Legislative actions, higher director and officer insurance costs and potential new accounting pronouncements are likely to cause our general and administrative expenses to increase and impact our future financial condition and results of operations.

In order to comply with the Sarbanes-Oxley Act of 2002, as well as changes to the American Stock Exchange listing standards and rules adopted by the Securities and Exchange Commission, we have been required to strengthen our internal controls, hire additional personnel and retail additional outside legal, accounting and advisory services, all of which have caused and will continue to cause our general and administrative costs to increase. These and other costs of operating as a public company will continue to be a significant element of our general and administrative costs. Although we have not experienced any director and officer liability claims, insurers have increased and are likely to continue to increase premiums as a result of the (i) high claims rates they have incurred with other companies over the past years (ii) the high stock ownership position of some of our non-affiliated
shareholders, and (iii) our reduced operating performance, and so our premiums for our directors and officers insurance policies are likely to continue to increase. Changes in the accounting rules and auditing standards, including legislative and other proposals to account for employee stock options as a compensation expense among others, could materially increase the expenses that we incur and report under generally accepted accounting principles and adversely affect our operating results.

Our fiscal 2006 new contract bookings and fiscal 2007 opening backlog is significantly lower than any comparable fiscal period for the most recent prior periods. Additionally, our sales backlog is not necessarily indicative of revenues that we will actually realize in fiscal year 2006 or at all.

Our new contract bookings for fiscal 2006 were approximately $13.7 million as compared to an average of $27.2 million for the last four fiscal years. Our opening backlog for fiscal 2007 is approximately $9.9 million. The opening backlog for fiscal years 2002 through 2005 was in excess of approximately $20 million for each year. Although our open proposal base remains strong, there is no assurance that we will be able to bring a significant amount of these contracts to award status. Additionally, we may not actually generate revenues in fiscal 2007 for all items included in our estimated backlog at the end of our 2006 fiscal year. While we estimate that approximately 94% of this $9.9 million backlog is expected to be completed prior to the end of our 2007 fiscal year, we are not certain that these projects will be completed so that we can record these revenues by such date, or at all. During
fiscal 2006, we shipped approximately 82% of our February 25, 2005 backlog. Our backlog includes the total value of all contracts less the revenue earned on those contracts through the measurement date. Many of our government contracts are multi-year contracts and contracts with option years, and portions of these contracts are carried forward from one year to the next as part of our backlog. Certain of our large contracts provide that we will not receive payment until the services under those contracts are requested and performed. We cannot assure that cancellations or adjustments in the terms of these contracts might not occur.

Our operations could be hurt by terrorist attacks, war, disease and other activities or occurrences that make air travel difficult or reduce the willingness of our commercial airline customers to purchase our simulation products.

The demand for our various commercial simulation products and services is heavily dependent upon new orders from our commercial airline customers. In the event terrorist attacks, war, disease or other activities or occurrences make air travel difficult or reduce the demand or willingness of our customers to purchase our commercial simulation products, our revenue may decline.

Geo-political and other factors may also limit or restrict our employees ability to gain entrance to foreign locations to sell products or perform contract services.

There is limited trading activity in our common stock which could make it more difficult for our investors to sell their shares of our common stock.

Our common stock is listed on the American Stock Exchange. Our average daily trading volume on the American Stock Exchange during fiscal 2006 was 4,362 shares. This limited trading activity may make it more difficult for investors to sell larger blocks of our common stock at prevailing prices as there are generally a small number of participants in the market for our common stock and such sales may lower the market price of our common stock.

The market price of our common stock may be volatile.

The market price of securities of thinly traded public companies has historically faced significant volatility. Although our common stock is traded on the American Stock Exchange, it does not experience a significant average daily trading volume. Accordingly, if one stockholder elects to either purchase or sell a block of our common stock, it may have a significant effect on the price of our common stock. In addition, the stock market in recent years has experienced significant price and volume fluctuations that often have been unrelated or disproportionate to the operating performance of particular companies. Many factors that have influenced trading prices will vary from period to period, including:

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

| |  | changes in estimates by analysts;
| | - | ---------------------------------

| |  | market conditions in the industry;
| | - | ----------------------------------

| |  | announcements by competitors;
| | - | -----------------------------

| |  | results of litigation;
| | - | ----------------------

| |  | regulatory actions; and
| | - | -----------------------

| |  | general economic conditions.
| | - | ----------------------------

Any of these events would likely affect the market price of our common stock.

Our quarterly operating results may vary significantly from quarter to quarter.

Our revenues and earnings may fluctuate from quarter to quarter based on factors that include the following:

| |  | the number, size and scope of our projects;
| | - | -------------------------------------------

| |  | equipment purchases and other expenditures required for our business;
| | - | ---------------------------------------------------------------------

| |  | the number of bid and proposal efforts undertaken;
| | - | --------------------------------------------------

| |  | delays in sales or production;
| | - | ------------------------------

| |  | the level of employee productivity;
| | - | -----------------------------------

| |  | the adequacy of our provisions for losses;
| | - | ------------------------------------------

| |  | the accuracy of our estimate of resources required to complete ongoing projects; and
| | - | ------------------------------------------------------------------------------------

| |  | general economic conditions.
| | - | ----------------------------

Demand for our products and services in each of the markets we serve can vary significantly from quarter to quarter due to revisions in customer budgets or schedules and other factors beyond our control. Due to all of the foregoing factors, our results of operations may fall below the expectations of securities analysts and investors in a particular period. In this event, the price of our common stock may decline.

Our officers and directors own a significant amount of our common stock which permits them to exert significant influence over the direction of our business and affairs.

As of May 11, 2006, our directors and executive officers own an aggregate of approximately 44.8% on a fully converted basis of our outstanding common stock. Given our equity line agreement with H.F. Lenfest and the lack of a bank facility, it is expected that this percentage will increase as we request additional funds and issue additional preferred stock under this agreement. Accordingly, these persons, if they act together, will be able to exert control over the direction of our business and affairs.

Item 2. Properties

We own our executive offices and principal production facilities located on a five acre site in the County Line Industrial Park, Southampton, Pennsylvania in an approximately 100,000 square foot steel and masonry building. Approximately 85,000 square feet of the building is devoted to manufacturing and 15,000 square feet of this building is devoted to office space. The original building was erected in 1969 and additions were most recently made in 2001. As of February 24, 2006, this property was pledged as collateral to secure the performance of our obligations under our revolving credit facility with PNC Bank, National Association and our subordinated debt financing with H.F. Lenfest. Additionally, we rent office space at various sales and support locations throughout the world and at ETC-PZL Aerospace Industries, our Polish subsidiary.

We consider our machinery and plant to be in satisfactory operating condition. Increases in the level of operations beyond what we expect in the current fiscal year might require us to obtain additional facilities and equipment.

Item 3. Legal Proceedings

In April 2003, Boenning & Scattergood, Inc. (B&S) filed suit against the Company in the Court of Common Pleas in Philadelphia, Pennsylvania, seeking payment of $901,843.46 for financing fees allegedly due to B&S pursuant to the terms of an agreement for investment banking services, which was entered into with a predecessor of B&S (the B&S Agreement). B&S alleged that it contacted the investors in the Companys February 2003 financing transaction and that it earned the claimed financing fees pursuant to the terms of the B&S Agreement. On August 17, 2005 the Company entered into an agreement to settle this litigation. The agreement was entered into for the purpose of resolving contested claims and disputes as well as avoiding the substantial costs, expenses and uncertainties associated with protracted and complex litigation, and was not
an admission of fault or liability by either party. Under the guidance of FASB Statement No.5, an amount representing a probable settlement had been accrued in a prior period, so the payment under the settlement had no material impact on the Companys results of operations for the fiscal second quarter.

In June 2003, Entertainment Technology Corporation (EnTCo), our wholly-owned subsidiary, filed suit against Walt Disney World Co. and other entities (Disney) in the United States District Court for the Eastern District of Pennsylvania, alleging breach of contract for, among other things, failure to pay all amounts due under contract for the design and production of the amusement park ride Mission: Space located in Disneys Epcot Center. In response, in August 2003, Disney filed counterclaims against both EnTCo and us (under a guarantee) for, among other things, alleged failures in performance and design in the contract. Disney is seeking damages in excess of $65 million plus punitive damages. Both EnTCo and we believe that we have valid defenses to each of Disneys counterclaims and intend to vigorously defend ourselves against these
counterclaims. Discovery has been completed and the parties participated in a structured mediation in early December 2005, with no agreement forthcoming as of the date of this Annual Report on Form 10-K. The case is not currently scheduled for trial. Neither EnTCo nor we are able to predict the outcome of this matter.

Certain other claims, suits, and complaints arising in the ordinary course of business have been filed or are pending against us. In our opinion, after consultation with legal counsel handling these specific maters, all such matters are reserved for or adequately covered by insurance or, if not so covered, are without merit or are of such kind, or involve such amounts, as would not have a significant effect on our financial position or results of operations if disposed of unfavorably.

Item 4. Submission of Matters to a Vote ofSecurity Holders

No matters were presented to our stockholders during the fourth quarter of fiscal 2006.

PART II

Item 5. Market for the Registrants Common Stock and Related Security Holder Matters

On April 7, 2006, ETC entered into a Preferred Stock Purchase Agreement (the Agreement) with H. F. Gerry Lenfest, a Director, significant shareholder and holder of our subordinated debt. The Agreement permits us to unilaterally draw down up to $15 million over the next eighteen (18) months in exchange for shares of our newly-created Series B Cumulative Convertible Preferred Stock (Preferred Stock). The Preferred Stock provides for a dividend equal to six (6) percent per annum. After three (3) years, the Preferred Stock will be convertible, at Mr. Lenfests request, into ETC common shares at a conversion price (the Conversion Price) which will be set on the day of each draw down. The Conversion Price will be equal to the closing price of our common stock on the trading day immediately preceding the day in which the draw down occurs,
subject to a floor price of $4.95 per common share. Drawdowns will not be permitted on any day when the Conversion Price would be less than this floor price. On the sixth anniversary of the Agreement, any issued and outstanding Preferred Stock will be mandatorily converted into ETC common stock at each set Conversion Price. The Agreement also allows us to redeem any outstanding Preferred Stock any time within the six (6) year term of the Agreement. The Preferred Stock will vote with the ETC common stock on an as converted basis.

In connection with the execution of the Agreement, we drew down $3 million by issuing 3,000 shares of Preferred Stock with a Conversion Price equal to $4.95 per share. The proceeds are being used for general corporate purposes.

Additionally, see information appearing under the heading Market for the Registrants Common Stock and Related Stockholder Matters and Issuer Purchases of Equity Securities in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference.

Item 6. Selected Consolidated Financial Data

See information appearing under the heading Financial Review in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference.

Item 7. Managements Discussion and Analysis of Financial Condition and Results of Operations

See information appearing under the heading Managements Discussion and Analysis of Financial Condition and Results of Operations in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to various market risks, including changes in interest rates. Market risk is the potential loss arising from adverse changes in market rates and prices, such as interest rates and foreign currency exchange rates. We do not enter into derivatives or other financial instruments for trading or speculative purposes. We also have not entered into financial instruments to manage and reduce the impact of changes in interest rates and foreign currency exchange rates although we may enter into such transactions in the future. Although currently none of our debt bears interest at rates that vary with the prime rate of interest, it is expected that any additional debt which we might incur would carry a floating rate. If this were the case, any increases in the applicable prime rate of interest would reduce our earnings. With respect to currency risk, where we have a contract which is
denominated in a foreign currency, we often establish local in-country bank accounts and fund in-country expenses in the local currency, thus creating a natural currency hedge for a portion of the contract.

Item 8. Financial Statements and Supplementary Data

See the information appearing under the headings Consolidated Financial Statements and Notes to Consolidated Financial Statements in the Annual Report to Stockholders attached hereto as Exhibit 13 and incorporated herein by reference.

Item 9. Changes in and Disagreements withAccountants on Accounting and Financial Disclosure

Not applicable.

Item 9A. Controls and Procedures

Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of February 24, 2006 (the Evaluation Date), and, based on this evaluation, our chief executive officer and chief financial officer have concluded that these controls and procedures were effective as of the Evaluation Date. There were no significant changes in our internal controls or in other factors that could significantly affect these controls subsequent to the Evaluation Date.

Back to Contents

Disclosure controls and procedures (as defined in Rules 13a-14(c) and 15(d)-14(c) under the Securities Exchange Act of 1934, as amended) are our internal controls and other procedures that are designed to ensure that information we are required to disclose in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commissions rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file under the Exchange Act is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the internal control system are met. Because of the inherent limitations of any internal control system, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected.

Compliance With Section 16(a) of the Exchange Act

Section 16(a) of the Securities Exchange Act of 1934 requires our officers and directors, and persons who own more than ten percent of a registered class of our equity securities to file reports of ownership and changes in ownership with the Securities and Exchange Commission (SEC) and the American Stock Exchange. Officers, directors and greater than ten percent shareholders are required by SEC regulations to furnish us with copies of all Section 16(a) reports they file. The rules of the SEC regarding the filing of Section 16(a) reports require that late filings of Section 16(a) reports be disclosed in our proxy statement.

Based solely on our review of the copies of such forms which we received, or written representations from reporting persons that no Section 16(a) reports were required for those persons, Messrs. Mitchell, Kelley, Anderson and Gemmill each had one late filing. We believe that our greater than ten percent beneficial owners complied with all applicable filing requirements.

Item 13. Certain Relationships and Related Transactions

On February 19, 2003, we completed a refinancing of our indebtedness with the PNC Bank, National Association and H.F. Lenfest inthe aggregate amount of $29,800,000. Pursuant to the terms of a Convertible Note and Warrant Purchase Agreement, dated February 18, 2003, between us and Mr. Lenfest, we issued to Mr. Lenfest (i) a 10% senior subordinated convertible promissory note in the original principal amount of $10,000,000 and (ii) warrants to purchase 803,048 shares of our common stock. As a condition to closing the financing, we appointed Mr. Lenfest to our Board of Directors. On October 25, 2004, Mr. Lenfest executed a Limited Guaranty Agreement which guaranteed the Companys $5 million Letter of Credit facility with PNC, and in connection therewith, we issued a Stock Purchase Warrant to
Mr. Lenfest pursuant to which Mr. Lenfest was entitled to purchase up to 200,000 shares of our common stock at an exercise price equal to the lesser of $4.00 per share or 2/3 of the average daily high and low closing price of our common stock during the 25 day trading period immediately preceding the date of exercise. On February 14, 2005 Mr. Lenfest exercised all of his outstanding warrants and received 1,003,048 shares of unregistered common stock and purchased an additional 373,831 shares of unregistered common stock for approximately $2 million. Under the American Stock Exchange listing rules, shareholder approval was required for this transaction and was included as a proxy item at our annual meeting in 2005. Shareholder approval was received at our 2005 annual meeting.

On April 6, 2006, the Company entered into a Preferred Stock Purchase Agreement (the Agreement) with Mr. Lenfest. The Agreement permits us to unilaterally draw down up to $15 million over the next eighteen (18) months in exchange for shares of the Companys newly-created Series B Cumulative Convertible Preferred Stock (Preferred Stock). The Preferred Stock provides for a dividend equal to six (6) percent per annum. After three (3) years, the Preferred Stock will be convertible, at Mr. Lenfests request, into ETC common shares at a conversion price (the Conversion Price) which will be set on the day of each draw down. The Conversion Price will be equal to the closing price of the Companys common stock on the trading day immediately preceding the day in which the draw down occurs, subject to a floor price of $4.95 per common share.
Drawdowns will not be permitted on any day when the Conversion Price would be less than this floor price. On the sixth anniversary of the Agreement, any issued and outstanding Preferred Stock will be mandatorily converted into ETC common stock at each set Conversion Price. The Agreement also allows for the Company to redeem any outstanding Preferred Stock any time within the six (6) year term of the Agreement. The Preferred Stock will vote with the ETC common stock on an as converted basis.

In connection with the execution of the Agreement, the Company drew down $3 million by issuing 3,000 shares of Preferred Stock with a Conversion Price equal to $4.95 per share.

For a more detailed description of the financing provided by Mr. Lenfest and PNC, see the Liquidity and Capital Resources section of the Annual Report to Stockholders attached as Exhibit 13 to this Annual Report on Form 10-K and incorporated herein by reference.

Prior to the consummation of the February 19, 2003 refinancing, ATAM, a shareholder and a holder of warrants to purchase 332,820 shares of our common stock, consented to the financing transactions with PNC and Mr. Lenfest including the below market issuance of warrants to Mr. Lenfest. As a result of its consent, ATAM waived, solely in connection with such issuance, the anti-dilution rights contained in its warrant. In exchange for ATAMs consent and waiver, we issued to ATAM warrants to purchase an additional 105,000 shares of common stock. Except for the number of shares issuable upon exercise of the warrants, the new ATAM warrants had substantially the same terms as the warrants issued to Mr. Lenfest. As of the date that these warrants were issued to ATAM, it was the beneficial owner of greater than 5% of our common stock as determined in accordance with Rule 13d-3
under the Securities Exchange Act of 1934. In fiscal year 2005, ATAM exercised all its warrants and received a total of 437,820 shares of our common stock.

Item
  14. Principal Accounting Fees and Services

Under the Companys Bylaws and the charter of the Audit Committee of the Board of Directors, authority to select the Companys auditors rests with the Audit Committee of the Board of Directors. Such selection is made through formal act of the Audit Committee. It has not been and is not the Companys policy to submit selection of its auditors to the vote of the shareholders because there is no legal requirement to do so. Grant Thornton LLP, an independent registered public accounting firm, was the Companys auditor for the fiscal year ended February 24, 2006. Auditors have not been selected for the current fiscal year. A representative of Grant Thornton is expected to be present at the Annual Meeting and will be given an opportunity to make a statement to the shareholders, if he or she desires to do so. Grant Thorntons representative will also be available to answer
appropriate questions from shareholders.

Set forth below is information relating to the aggregate Grant Thornton LLP fees for professional services provided to the Company for the fiscal year ended February 24, 2006:
