1. Basis of Preparation



The
accompanying unaudited consolidated financial statements of ADE Corporation (the Company) include, in the opinion of management, all adjustments (consisting only of normal and recurring adjustments) necessary for a fair statement of the
Companys financial position, results of operations and cash flows at the dates and for the periods indicated. Results of operations for interim periods are not necessarily indicative of those to be achieved for full fiscal years.



Pursuant to accounting requirements of the Securities and Exchange
Commission (SEC) applicable to quarterly reports on Form 10-Q, the accompanying unaudited consolidated financial statements and these notes do not include all disclosures required by generally accepted accounting principles
(GAAP) in the United States of America for complete financial statements. Accordingly, these statements should be read in conjunction with the financial statements included in the Companys Annual Report on Form 10-K for the fiscal
year ended April 30, 2005. The Company maintains a website where copies of its reports filed with SEC may be accessed as well as other information concerning the Companys business, products and news releases. The address of the Companys
website is www.ade.com. The Companys website is included as a textual reference only and the information on the Companys website is not incorporated by reference into this Quarterly Report on Form 10-Q.



The preparation of financial statements in conformity with GAAP requires
management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses and the disclosure of contingencies in the Companys unaudited consolidated financial statements. Areas particularly
subject to estimation include the allowance for doubtful accounts, the valuation for potential excess and obsolete inventory, the carrying value of the Companys intangible assets and the valuation allowance on deferred tax assets. Actual
results could differ from those estimates.

4. Intangible Assets



The Company has capitalized license fees for software
included in the Companys products. These license fees are amortized at the greater of 1) the ratio that current gross revenue for the related products bears to the total current and anticipated future gross revenue for those products or 2) on
a straight-line basis over the estimated useful life of the related products. The carrying amount and accumulated amortization for the Companys intangible assets are as follows:



|                         |  |                |       |   |               |   |       |

6. Stock-based Compensation



Stock-based compensation awards to employees under the Companys stock plans are accounted for using the intrinsic
value method prescribed in Accounting Principles Board Opinion (APB) No. 25, Accounting for Stock Issued to Employees, and related interpretations. The Company has adopted the disclosures required by Statement of Financial
Accounting Standards (SFAS) No. 123 (SFAS 123), Accounting for Stock-Based Compensation and SFAS No. 148, Accounting for Stock-based Compensation. Had compensation cost for the stock-based compensation
been determined based on the fair value at the grant dates of awards consistent with the provisions of SFAS 123, the Companys net income and earnings per share would have been reduced to the pro forma amounts as follows:

7. Earnings Per Share



Earnings per share are presented in accordance with SFAS No. 128, Earnings Per Share, which requires the presentation of basic
earnings per share and diluted earnings per share. Basic earnings per share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings
per share is computed using the weighted average number of common shares outstanding and gives effect to all dilutive potential common shares outstanding during the period. Potential common shares include shares issuable upon the assumed exercise of
dilutive stock options. For the three months ended July 31, 2005 and 2004, respectively, 24,250 and 257,560 common shares issuable upon the exercise of stock options have been excluded from the computation of diluted earnings per share, as their
effect would have been antidilutive because the exercise price of the options was greater than the average market value of the Companys common stock during the respective periods.



The following is a reconciliation of the shares used in calculating basic and diluted earnings per share:

8. Segment Reporting



The Company has three reportable segments: ADE
Semiconductor Systems Group (SSG), ADE Phase Shift (PST) and ADE Technologies (ATI). SSG manufactures and markets metrology and inspection systems to the semiconductor wafer and device manufacturing industries
that are used to improve yield and capital productivity. Sales of the Companys stand-alone software products are also included in the SSG segment. PST manufactures and markets high performance, non-contact surface metrology equipment using
advanced interferometric technology that provides enhanced yield management to the data storage, semiconductor wafer and device manufacturing and optics industries. ATI manufactures and markets high precision magnetic characterization and
non-contact dimensional metrology gauging systems primarily to the data storage industry.



The Companys reportable segments are determined based upon information used to evaluate the business by the chief operating decision maker, which includes the nature of the products, the external customers and
customer industries and the sales and distribution methods used to market the products. The Company evaluates performance based upon profit or loss from operations. The Company does not measure the assets allocated to the segments. Management fees
representing certain services provided by corporate offices have been allocated to each of the reportable segments based upon the usage of those services by each segment. Additionally, other income and the provision for income taxes are not included
in segment profitability. For the reportable segments, intersegment sales are recorded at cost plus 20% and are eliminated in consolidation.

9. Commitments and Contingencies



Litigation



From time to time the Company is subject to legal proceedings and claims in the ordinary course of business. In the opinion of management, the amount of
ultimate expense with respect to any current legal proceedings and claims will not have a material adverse effect on the Companys financial position or results of operations.



Guarantor agreements



The Company has an agreement with a vendor whereby it guarantees the expenses incurred by certain of the Companys employees. The term of the
agreement is from execution until cancellation and payment of any outstanding amounts. The Company would be required to pay any unsettled employee expenses upon notification from the vendor. The maximum potential amount of future payments the
Company could be required to make under this agreement is not significant. As a result, the Company believes the estimated fair value of these agreements is minimal. Accordingly, no liabilities have been recorded for this guaranty as of July 31,
2005.



Pursuant to one of the provisions in the Companys
standard terms and conditions of sale, the Company agrees, subject to certain limitations and conditions, to defend any suit or proceeding brought against a customer based on a claim that the Companys equipment, standing alone, infringes a
United States patent or copyright or misappropriates a trade secret protected under United States law. Actions arising under such provision may only be brought by customers within two years after the cause of action arises. The maximum potential
amount of payments the Company may be required to make under such provision is limited to the total purchase price of the Companys equipment sold under the particular contract. The Company has never incurred costs to defend lawsuits or settle
claims related to these customer contract provisions. As a result, the Company believes the estimated exposure of these provisions is minimal. Accordingly, the Company has no liabilities recorded for these provisions as of July 31, 2005.



The Company warrants that its products will perform in all material
respects in accordance with its standard published specifications. The term of the Companys standard warranty is 12 months. The Company currently accrues 2% of product revenues, based on history, to provide for estimated warranty costs. The
following is a reconciliation of the quarterly activity in the Companys warranty liability for the three months ended July 31, 2005 and 2004.

10. New Accounting Pronouncements



In November 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 151, Inventory
Costs (SFAS 151). SFAS 151 amends the guidance in Accounting Review Board No. 43, Chapter 4, Inventory Pricing, to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and
wasted material (spoilage). SFAS 151 is effective for fiscal years beginning after June 15, 2005. The adoption of SFAS 151 is not expected to have a material impact on the Companys financial position and results of operations.



In December 2004, the FASB issued SFAS No. 123 (revised 2004),
Share-Based Payment (SFAS 123R). SFAS 123R requires that the cost resulting from all share-based payment transactions be measured using a fair-value method and be recognized in the financial statements. SFAS 123R is effective
as of the beginning of the first interim or annual reporting period of the first fiscal year that begins on or after June 15, 2005. SFAS 123R is effective for the Companys first quarter of fiscal 2007 beginning May 1, 2006. SFAS 123R permits
public companies to adopt its requirements using one of two methods:



| | 1. | A modified prospective method in which compensation cost is recognized beginning with the effective date (a) based on the requirements of SFAS 123R for all share-based
payments granted after the effective date and (b) based on the requirements of SFAS 123 for all awards granted to employees prior to the effective date of SFAS 123R that remain unvested on the effective date.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | A modified retrospective method which includes the requirements of the modified prospective method described above, but also permits entities to restate based on the
amounts previously recognized under SFAS 123 for purposes of pro forma disclosures for either (a) all prior periods presented or (b) prior interim periods of the year of adoption.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



The Company has not yet determined whether it will adopt SFAS 123R using the
modified prospective method or the modified retrospective method. Management is currently evaluating the impact that the adoption of SFAS 123R will have on the Companys financial position and results of operations.



11. Income Taxes



For the three months ended July 31, 2005, the Company earned income before taxes of $4.0 million and recorded a tax
provision of $1.1 million. The Companys effective tax rate in the first quarter of fiscal 2006 was approximately 28% compared to 3% in the first quarter of fiscal 2005. The current quarter rate includes an adjustment to the estimated benefit
of prior year research and development credits. The provision for income taxes in the first quarter of fiscal 2005 consisted only of federal and state alternative minimum taxes and foreign income taxes because at that time, the Company had a full
valuation allowance against its deferred tax assets.

Item 2. Managements Discussion and Analysis of Financial Condition and Results of Operations:



Introduction



ADE Corporation (the Company) designs, manufactures, markets and services highly precise, automated measurement, defect detection and handling
equipment with current applications in the production of semiconductor wafers, semiconductor devices and magnetic computer disks. The Company operates three major business segments, the Semiconductor Systems Group (SSG), ADE Phase Shift
(PST) and ADE Technologies (ATI). SSG manufactures multifunctional semiconductor metrology and automation systems and optical wafer defect inspection equipment used to detect particles and other defects on silicon wafer
surfaces primarily for the semiconductor wafer and device manufacturing industries. PST manufactures high-performance, non-contact surface metrology equipment using advanced interferometric technology that provides enhanced yield management to the
data storage, semiconductor and optics industries. ATI manufactures high precision magnetic characterization and non-contact dimensional metrology gauging systems primarily for the data storage industry.



Historically, the semiconductor wafer and device industries and the magnetic
data storage industry have been highly cyclical and have experienced both rapid periods of growth and rapid downturns that can be abrupt and result in significant changes in revenue and profits. During an industry wide downturn, the demand for
capital equipment significantly decreases as the Companys customers reduce production of semiconductor wafers and devices. Beginning in the second half of fiscal 2003 and continuing through the fourth quarter of fiscal 2005, the Company
experienced sequential increases in quarterly revenue in all but the first quarter of fiscal 2004. As a result, the Company has achieved profitability, on a quarterly basis, since the third quarter of fiscal year 2003. These results were due in part
to increased worldwide order activity during fiscal 2003, 2004 and early fiscal 2005. However, since the first quarter of fiscal 2005, the Company has experienced decreased order levels and, for the first time since the first quarter of fiscal 2004,
the Company recorded a decrease in sequential quarterly revenue in the first quarter of fiscal 2006. In spite of the recent decrease in order levels and this quarters decrease in revenue, the Company has maintained its profitability, albeit at
a reduced level. At this time, due to limited industry visibility, the Company cannot determine if this decrease in order activity will continue and if so, for how long. As such, the Company makes no assurances that current order, revenue, backlog,
and profit levels can be sustained in future periods. The Company expects that order levels will increase later in fiscal 2006 as the industry strengthens and the Companys new products gain acceptance.



The following information should be read in conjunction with the unaudited
consolidated financial statements and notes thereto included in this quarterly report and the audited consolidated financial statements and Managements Discussion and Analysis of Financial Condition and Results of Operations contained in the
Companys Annual Report on Form 10-K for the fiscal year ended April 30, 2005.



Forward-Looking Statements



This quarterly
report on Form 10-Q contains statements which constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 and Federal securities laws. Statements that make reference to the Companys
expectations, predictions and anticipations are subject to known and unknown risks and uncertainties that could cause actual results to differ materially from those expressed by such statements and should be considered forward-looking statements.
These statements include, but are not limited to, expectations about the Companys performance in the second quarter and remainder of fiscal 2006, risks and uncertainties associated with the strength of the semiconductor and magnetic data
storage markets, wafer pricing and wafer demand, the results of product development efforts and expected demand for, and acceptance of, new and existing products, the success of the Companys product offerings in meeting customer needs within
the timeframes required by customers in these markets, further increases in backlog, the Companys limited visibility with respect to its industrys long term trends, the Companys ability to maintain current gross profit levels,
expectations about the impact of Statement of Financial Accounting Standards (SFAS) No. 123 (revised 2004) and its predictions of future financial outcomes. Subject to applicable law, the Company disclaims any intent or obligation to
update publicly any forward-looking statements, whether as a result of new information, future events or otherwise. Further information on potential factors that could affect the Companys business is described in Other Risk Factors and

Critical Accounting Policies, Significant Judgments and Estimates



The discussion and analysis of the Companys financial condition and results of operations are based upon its consolidated financial statements,
which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts
of assets, liabilities, revenues and expenses, and related disclosure at the date of the Companys financial statements. On an ongoing basis, management evaluates its estimates and judgments, including those related to bad debts, inventories,
intangible assets, income taxes, and warranty obligations. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the
basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. The Company considers certain
accounting policies related to revenue recognition and allowance for doubtful accounts, inventory valuation, accounting for income taxes and the valuation of goodwill and software to be critical policies due to the estimates and judgments involved
in each.



Revenue Recognition and Allowance for Doubtful Accounts



The Companys revenue recognition policy complies
with SEC Staff Accounting Bulletin No. 104, Revenue Recognition in Financial Statements (SAB 104). The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been
rendered, the price is fixed or determinable and collectibility is reasonably assured. The Companys standard customer arrangement includes a signed purchase order, in which it offers payment terms of 30 to 90 days, no right of return of
delivered products and a twelve month warranty. The Company assesses whether the fee associated with its revenue transactions is fixed or determinable based on the payment terms associated with the transaction. If a significant portion of the fee is
due after the Companys normal payment terms, 30 to 90 days, it determines that the fee is not fixed or determinable. In these cases, the Company recognizes revenue as the fees become due. The Company assesses collectibility based on the credit
worthiness of the customer and past transaction history. The Company performs initial credit evaluations of its customers and does not require collateral from its customers. For many of the Companys international customers, it requires that an
irrevocable letter of credit be issued by the customer before the purchase order is accepted. If the Company determines that collection of a fee is not reasonably assured, it defers the fee and recognizes the revenue at the time that collection
becomes reasonably assured, which is generally upon the receipt of cash.



For some of the Companys sales transactions, a portion, usually 10%, of the fee is not due until installation occurs and the customer accepts the product. The other 90% of the fee is normally due 30 to 90 days
after shipment. If the Company has met defined customer acceptance experience levels with a specific type of product, these transactions are accounted for as multiple-element arrangements with the deferral of the portion of the fee not due until
installation is complete and customer acceptance has occurred. Management of the Company must make a determination of what constitutes an appropriate experience level with a product. This determination is based on, but not limited to, the extent to
which a product contains significantly new technology, the number of similarly configured products previously delivered and the Companys experience with a particular customer. For new products, the Company must obtain at least three
acceptances before it will recognize the 90% portion of the fee upon shipment. All other sales with customer acceptance provisions are recognized as revenue upon customer acceptance. The portion of the fee related to the installation of the product
and customer training is classified as service revenue.



The
Companys transactions frequently involve the sales of systems and services under multiple element arrangements. Revenue under multiple element arrangements is allocated to all elements except systems based upon the fair value of those
elements. The amounts allocated to training are based upon the price charged when this



14

##### Table of Contents

element is sold separately and unaccompanied by the other elements. The amount allocated to installation revenue is based upon hourly rates and the estimated
time to complete the service. The amount allocated to system and parts is done on a residual method basis. Under this method, the total arrangement value is allocated first to undelivered elements, based on their fair values, with the remainder
being allocated to system revenue.



The Company accrues for
anticipated warranty costs upon shipment. Service revenue is recognized as the services are performed provided collection of the related receivable is probable. Service contract revenue is recognized ratably over the contractual periods in which the
services are provided. Revenue from software licenses is recognized when an agreement has been executed, software has been delivered, fees are fixed or determinable and collection of the related receivable is probable.



The Company maintains an allowance for doubtful accounts based on a
continuous review of customer accounts, payment patterns and specific collection issues. Where specific collection issues are identified, the Company records a specific allowance based on the amount that the Company believes will be collected. For
accounts where specific collection issues are not identified, the Company will record a reserve based on the age of the receivable and historical collection patterns.



Inventory Valuation



Inventories are valued at the lower of cost or market, cost being determined on a first-in, first-out basis. Management evaluates the need to record
adjustments for impairment of inventory on a monthly basis. The Companys policy is to assess the valuation of all inventories, including raw materials, work-in-process, finished goods and spare parts. Inventory that, in the judgment of
management, is obsolete or in excess of the Companys estimated usage is written-down to its estimated market value, if less than its cost. Inherent in the estimates of market value are managements estimates related to current economic
trends, future demand for the Companys products, and technological obsolescence. Significant management judgments must be made when establishing the reserve for obsolete and excess inventory. If the Companys judgments and estimates
relating to obsolete and excess inventory prove to be inadequate, its financial results could be materially adversely affected in future periods. If the inventory value is written down to its net realizable value, and subsequently there is an
increased demand for the inventory at a higher value, the increased value of the inventory is not realized until the inventory is sold.



Accounting for Income Taxes



The Company records income taxes using the asset and liability method. Deferred income tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective income tax bases, and operating loss and tax credit carryforwards. The Companys financial
statements contain certain deferred tax assets, which have arisen primarily as a result of operating losses incurred in prior years, as well as other temporary differences between book and tax accounting. SFAS No. 109, Accounting for Income
Taxes, requires the establishment of a valuation allowance to reflect the likelihood of the realization of deferred tax assets. Significant management judgment is required in determining the Companys provision for income taxes, its
deferred tax assets and liabilities and any valuation allowance recorded against its net deferred tax assets. The Company evaluates the weight of all available evidence to determine whether it is more likely than not that some portion or all of the
deferred income tax assets will not be realized. The amount of the deferred tax asset considered realizable is based on significant estimates, and it is at least reasonably possible that changes in these estimates in the near term could materially
affect the Companys financial condition and results of operations. The Companys effective tax rate may vary from period to period based on changes in estimated taxable income or loss, changes to the valuation allowance, changes to
federal, state or foreign tax laws, and deductibility of certain costs and expenses by jurisdiction.

Valuation of Goodwill and Software



As of July 31, 2005, intangible assets consist of $1.3 million of goodwill obtained through the acquisition of the
Semiconductor Solutions Division of LPA Software, Inc. in September 1997 as well as $0.5 million, net of amortization, of capitalized license fees for software included in the Companys products. The Company accounts for goodwill and other
intangible assets in accordance with SFAS No. 142 (SFAS 142), Goodwill and Other Intangible Assets.



The Company is required to perform impairment tests under SFAS 142 annually during the fourth quarter and whenever events or changes in circumstances
suggest that the goodwill may be impaired. Factors the Company considers important that could trigger the impairment review include:



| |  | significant underperformance relative to historical or projected future operating results;
|- |  | ------------------------------------------------------------------------------------------



| |  | significant negative industry or economic trends;
|- |  | -------------------------------------------------



| |  | significant adverse change in legal factors or in the business climate;
|- |  | -----------------------------------------------------------------------



| |  | significant decline in the Companys stock price for a sustained period;
|- |  | ------------------------------------------------------------------------



| |  | significant decline in the Companys technological value as compared to the market;
|- |  | -----------------------------------------------------------------------------------



| |  | the Companys market capitalization relative to net book value; and
|- |  | -------------------------------------------------------------------



| |  | unanticipated competition.
|- |  | --------------------------



Net capitalized license fees of $0.5 million for software included in the Companys products are amortized at the greater of 1) the ratio that
current gross revenue for the related products bears to the total current and anticipated future gross revenue for those products or 2) on a straight-line basis over its estimated useful life. At each quarter-end, the carrying value of the software
is compared to net realizable value (NRV). NRV is the estimated future gross revenues from products that incorporate the software reduced by the estimated future costs of disposal. If NRV is less than the carrying value, the excess is
written-off and NRV becomes the new carrying value of the software.



Significant management judgments and estimates must be made when establishing criteria for future cash flows, estimating reporting unit fair value and assessing impairment. If the Companys judgments and estimates relating to goodwill
and software prove to be inadequate, an asset may be determined to be impaired and the Companys financial results could be materially adversely impacted. Likewise, if a future event or circumstance indicates that an impairment assessment is
required and, through the performance of that assessment, an asset is determined to be impaired, the Companys financial results could be materially and adversely impacted in future periods.



Off-Balance Sheet Arrangements



The Company has not created, and is not party to, any special-purpose or
off-balance sheet entities for the purpose of raising capital, incurring debt or operating parts of its business that are not consolidated into its financial statements. The Company does not have any arrangements or relationships with entities that
are not consolidated into its financial statements that are reasonably likely to materially affect its liquidity or the availability of capital resources, except as set forth below under Liquidity and Capital Resources.

Results of Operations



Three Months Ended July 31, 2005 compared to Three Months Ended July 31, 2004



Systems and parts revenue.Systems and parts revenue decreased 14% to $21.7 million in the first
quarter of fiscal 2006 from $25.3 million in the first quarter of fiscal 2005. Systems and parts revenue in the SSG segment decreased 48% to $8.9 million in the first quarter of fiscal 2006 compared to $17.2 million in first quarter of fiscal 2005.
The decrease in revenues from the SSG segment reflects both decreased orders for capacitance-based flatness tools in favor of the Companys newer optical-based flatness tools, which are sold by the Companys PST segment, and decreased
demand for the companys Advanced Wafer Inspection System as the companys latest-generation nano-particle inspection and defect classification tool, the WaferXam, is scheduled to begin shipping in the second quarter of fiscal 2006.
Systems and parts revenue in the PST segment increased 81% to $10.0 million in the first quarter of fiscal 2006 compared to $5.6 million in the first quarter of fiscal 2005. The increase in revenue from the PST segment was due primarily to increased
demand for its optical-based flatness tools. System and parts revenue from the products that are marketed to the data storage industry by the Companys ATI segment increased 13% to $3.2 million in the first quarter of fiscal 2006 compared to
$2.8 million in the first quarter of fiscal 2005. The increase can be attributed primarily to increased demand for magnetics parts as the installed base of ATIs magnetics products continues to increase. For the second quarter of fiscal 2006,
the Company expects consolidated revenue, which consists primarily of revenue from the semiconductor industry, to be within a range of $23.0 to $24.0 million.

The geographical
distribution of revenues can fluctuate from quarter to quarter due to differences in the timing and rate of capital expenditures by customers among geographical regions.



Service revenue. Service revenue decreased 13% to $2.6 million in the first quarter of fiscal 2006 compared to $3.0
million in the first quarter of fiscal 2005. The Companys service revenue consists of fees for installation, training, product maintenance, and technical support services. The majority of the Companys service revenue is derived from the
SSG segment. The decrease in revenue is primarily the result of fewer service calls during the first quarter of fiscal 2006 compared to the first quarter of fiscal 2005.



Gross profit  systems and parts. Gross profit on systems and parts increased to 62% in the first quarter of
fiscal 2006 from 56% in the first quarter of fiscal 2005. Gross profit in the SSG segment remained flat at 58% in the first quarter of fiscal 2006 compared to the first quarter of fiscal 2005. Gross profit in the PST segment increased to

##### Table of Contents

64% in the first quarter of fiscal 2006 compared to 56% in the first quarter of fiscal 2005 due primarily as a result of increased volume. Gross profit in
the ATI segment increased to 55% in the first quarter of fiscal 2006 compared to 39% in the first quarter of fiscal 2005 primarily due increased shipments of ATIs magnetic data storage products. Changes in product mix impact the Companys
gross profit. Consequently, the gross profit in one period may not be indicative of the gross profit in future periods.



Gross profit  service. Gross profit from service decreased to 9% in the first quarter of fiscal 2006 compared to 27% in the first quarter of
fiscal 2005. The decreased gross profit was the result of both fewer service calls and increased repair costs compared to the first quarter of fiscal 2005.



For the second quarter of fiscal 2006, the Company expects consolidated gross profit to be in the range of 53% to 54%.



Research and development. Research and development expense for the
first quarter of fiscal 2006 increased $0.2 million, or 5%, to $3.8 million compared to $3.6 million in the first quarter of fiscal 2005 and increased as a percentage of revenue to 16% compared to 13% in the first quarter of fiscal 2005. The
increase was due primarily to higher payroll expense. The increase in expense as a percentage of revenues primarily reflects the decreased revenue mentioned above. The Company expects research and development expense for the second quarter of fiscal
2006 to remain flat in absolute dollars compared to the first quarter of fiscal 2006. The Company continues to invest in its semiconductor wafer and device industry products as well as new products for the magnetic storage industry, including those
that measure the magnetic properties of materials used in manufacturing disk drives.



Marketing and sales. Marketing and sales expense remained unchanged at $3.5 million in the first quarter of fiscal 2006 compared to the first quarter of fiscal 2005, but increased to 14% as a percentage of
revenue compared to 12% in the first quarter of fiscal 2005. The increase in expense as a percentage of revenues primarily reflects the decreased revenue mentioned above. The Company expects marketing and sales expense to decrease in the second
quarter of fiscal 2006 to a range of $2.8 to $3.0 million due to lower commission expense as shipments to Japan are expected to increase. In general, sales to Japan are made to distributors who buy the Companys products at a discount and then
perform installation and service after reselling the products to the end user. Sales to other parts of the world are made through internal and external sales representatives who are compensated by means of commissions, which are recorded as sales
and marketing expense. The mix of sales channels through which the Companys products are sold may also have a significant impact on the Companys marketing and sales expense and the results in any period may not be indicative of marketing
and sales expense for future periods.



General and
administrative. General and administrative expense increased $0.1 million, or 4%, to $2.8 million in the first quarter of fiscal 2006 from $2.7 million in the first quarter of fiscal 2005 and increased as a percentage of revenue to 11% from 9%
in the first quarter of 2005. Expense increased primarily as a result of increased regulatory compliance expenses of $0.3 million, which were mostly offset by a decrease in payroll expense of $0.2 million. The increase in expense as a percentage of
revenues primarily reflects the decreased revenue mentioned above. The Company expects general and administrative expense to remain at or near current levels in absolute dollars in the second quarter of fiscal 2006 compared to the first quarter of
fiscal 2006.



Interest income. Interest income was $0.5
million in the first quarter of fiscal 2006 compared to interest income of $0.1 million in first quarter of fiscal 2005. The increase in interest income was the result of an increase in invested cash balances and increased investment returns during
the first quarter of fiscal 2006 compared to the first quarter of fiscal 2005.



Interest expense. Interest expense was $49,000 in the first quarter of fiscal 2006 compared to interest expense of $52,000 in the first quarter of fiscal 2005. The decrease in interest expense was primarily due
to a decrease in the principal balance of the Companys 1999 Industrial Development Bond for its Tucson, Arizona facility.



Income taxes. The provision for income taxes was $1.1 million in the first quarter of fiscal 2006 compared to a provision for income taxes of $0.1
million in the first quarter of fiscal 2005. The increase of $1.0 million was due primarily to increased federal income tax expense. In the fourth quarter of fiscal 2005, the Company reversed $17.2

million of its deferred tax asset valuation allowance and began to recognize a higher effective tax rate starting in the first quarter of fiscal 2006. The
Companys effective tax rate in the first quarter of fiscal 2006 was approximately 28% compared to 3% in the first quarter of fiscal 2005. The current quarter rate includes an adjustment to the estimated benefit of prior year research and
development credits. The Company expects its effective tax rate for the fiscal year ending April 30, 2006 to be approximately 33%. The provision for income taxes in the first quarter of fiscal 2005 consisted only of federal and state alternative
minimum taxes and foreign income taxes because at that time, the Company had a full valuation allowance against its deferred tax assets. The effective tax rate may vary from period to period based on changes in estimated taxable income or loss,
changes to the valuation allowance, changes to federal, state or foreign tax laws, and deductibility of certain costs and expenses by jurisdiction.



Liquidity and Capital Resources



At July 31, 2005, the Company had $78.1 million in cash and cash equivalents and $122.4 million in working capital.



Cash provided by operating activities for the three months ended July 31,
2005 was $3.9 million. This amount resulted from net income of $2.9 million adjusted for non-cash charges of $1.4 million and a $0.5 million net decrease in working capital accounts. Non-cash items consisted primarily of $0.5 million of depreciation
and amortization and a $1.0 million decrease in deferred income taxes. Working capital items consisted primarily of a decrease in accounts receivable of $0.4 million and accounts payable of $0.4 million combined with increases in inventory of $0.9
million, prepaid expenses and other current assets of $0.1 million and accrued expenses and other current liabilities of $0.7 million. The decrease in accounts receivable was due to a decrease in shipments during the first quarter of fiscal 2006.
The decrease in accounts payable was primarily due to the timing of payments to vendors. The increase in inventory was due to the timing of shipments. The increase in prepaid expenses and other current assets was due to the timing of payments to
vendors. The increase in accrued expenses and other current liabilities was primarily due to increases in accrued commissions of $0.9 million which was offset by a decrease in accrued warranty costs of $0.2 million.



Cash provided by investing activities for the three months ended July 31,
2005 consisted of $0.3 million in purchases of fixed assets. During the three months ended July 31, 2005, fixed assets of $45,000 were transferred to inventory.



Cash provided by financing activities for the three months ended July 31, 2005 was $1.7 million, which consisted of $1.8 million of aggregate proceeds
from the issuance of common stock from the exercise of stock options and stock purchased through the Companys employee stock purchase plan. These proceeds were slightly offset by $0.1 million of principal repayments of long-term debt.



Under Generally Accepted Accounting Principles
(GAAP) in the United States of America, certain obligations and commitments are not required to be included in the consolidated balance sheet. These obligations and commitments, while entered into in the normal course of business, may
have a material impact on liquidity. The Company does not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance, variable interest or special purpose entities, which
would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, the Company is not exposed to any financing, liquidity, market or credit risk that could arise if
the Company had engaged in such relationships.



The following
table discloses the Companys contractual payment obligations as of July 31, 2005. The operating lease and consulting agreement obligations are not included in the unaudited consolidated financial statements included in Item 1. Financial
Information. The principal portion of the long-term debt is included in the unaudited consolidated financial statements. The long-term debt payments in the table below include both principal and interest. The unconditional purchase order
obligations primarily represent open purchase orders for inventory, a significant portion of which is necessary to produce and ship orders from the Companys backlog.

The Company expects to
meet its anticipated working capital needs and capital expenditures primarily through available cash and cash equivalents, which will primarily be generated from sales to both existing and new customers. However, the Company can provide no assurance
that it will be able to maintain its current customer base or acquire new customers.



Other Risk Factors and Trends



Capital
expenditures by semiconductor wafer and device manufacturers historically have been cyclical as they in turn depend upon the current and anticipated demand for integrated circuits. While the semiconductor industry appeared to have emerged from the
most recent severe down cycle, it is not clear whether this recovery is still continuing for semiconductor wafer manufacturers, who have historically accounted for approximately 70% to 80% of the Companys revenue. In addition, the Company
cannot determine at this time if the current uncertainty in the industry is indicative of an impending slowdown or if the recent upward cycle will resume. The data storage industry has been in a period of oversupply and excess manufacturing capacity
for an extended period of time and this has also had an adverse impact on the Company. The data storage industry is also showing signs of recovery, but the outlook for sustained long-term growth in this industry is also uncertain. At July 31, 2005,
the Companys backlog was $42.1 million. The Company remains uncertain about how long current revenue levels can be sustained and whether it will experience further decreases in quarterly revenue as it did in the first quarter of fiscal 2006.
The Company continues to evaluate its cost structure relative to expected revenue and will continue to implement aggressive cost containment measures where necessary. However, the Company cannot provide assurance that it will be able to implement
cost containment measures in a timely or cost effective manner.



Furthermore, the Companys success is dependent upon supplying technologically superior products to the marketplace at appropriate times to satisfy customer needs. Product development requires substantial investment and is subject to
technological risks. Delays or difficulties in product development or market acceptance of newly developed products could adversely affect the future performance of the Company.

New Accounting Pronouncements



In November 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 151, Inventory
Costs (SFAS 151). SFAS 151 amends the guidance in Accounting Review Board No. 43, Chapter 4, Inventory Pricing, to clarify the accounting for abnormal amounts of idle facility expense, freight, handling costs, and
wasted material (spoilage). SFAS 151 is effective for fiscal years beginning after June 15, 2005. The adoption of SFAS 151 is not expected to have a material impact on the Companys financial position and results of operations.



In December 2004, the FASB issued SFAS No. 123 (revised 2004),
Share-Based Payment (SFAS 123R). SFAS 123R requires that the cost resulting from all share-based payment transactions be measured using a fair-value method and be recognized in the financial statements. SFAS 123R is effective
as of the beginning of the first interim or annual reporting period of the first fiscal year that begins on or after June 15, 2005. SFAS 123R is effective for the Companys first quarter of fiscal 2007 beginning May 1, 2006. SFAS 123R permits
public companies to adopt its requirements using one of two methods:



| | 1. | A modified prospective method in which compensation cost is recognized beginning with the effective date (a) based on the requirements of SFAS 123R for all share-based
payments granted after the effective date and (b) based on the requirements of SFAS 123 for all awards granted to employees prior to the effective date of SFAS 123R that remain unvested on the effective date.
| | -- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | 2. | A modified retrospective method which includes the requirements of the modified prospective method described above, but also permits entities to restate based on the
amounts previously recognized under SFAS 123 for purposes of pro forma disclosures for either (a) all prior periods presented or (b) prior interim periods of the year of adoption.
| | -- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



The Company has not yet determined whether it will adopt SFAS 123R using the
modified prospective method or the modified retrospective method. Management is currently evaluating the impact that the adoption of SFAS 123R will have on the Companys financial position and results of operations.

Item 3. Quantitative and Qualitative Disclosures About Market Risk:



At July 31, 2005, the Companys exposure to market risk relates primarily to changes in interest rates on its investment portfolio. The
Companys cash equivalents consist primarily of fixed income securities. The Company invests only with high credit quality issuers and does not use derivative financial instruments in its investment portfolio. The Company does not believe that
a sharp increase or decrease in interest rates would have a material adverse impact on the fair value of its investment portfolio. The Companys long-term borrowings are at fixed interest rates.



In addition, a portion of the Companys business is conducted outside
the United States through its foreign subsidiaries and an affiliate. The Company generally transacts business in international markets in United States currency, but pays its employees in local currencies. Accordingly, the Company is subject to
exposure from adverse movements in foreign currency exchange rates. Historically, the Companys exposure to adverse foreign currency fluctuations has been immaterial.



Item 4. Controls and Procedures:



Conclusion
Regarding the Effectiveness of Disclosure Controls and Procedures



Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined
under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended. Based on this evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were
effective as of the end of the period covered by this Quarterly Report.



Changes to Internal Control Over Financial Reporting



There have been no changes to the Companys internal control over financial reporting during the first quarter of fiscal 2006 that have materially affected, or are reasonably likely to materially affect, the Companys internal
control over financial reporting.
