ELECTRO SCIENTIFIC INDUSTRIES, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis
of Presentation

These unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles have been condensed or
omitted in these interim statements. Accordingly, these condensed consolidated financial statements are to be read in conjunction with the financial statements and notes included in the Companys Annual Report on Form 10-K. These interim
statements include all adjustments (consisting of only normal recurring adjustments and accruals) necessary for a fair presentation of results for the interim periods presented. The results for interim periods are not necessarily indicative of the
results of operations for the entire year.

The preparation of financial statements in conformity with accounting principles generally
accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of commitments and contingencies at the date of the financial statements and the reported
amounts of revenues and expenses during the reporting periods. Actual results may differ from those estimates. Management believes that the estimates used are reasonable. Significant estimates made by management include: revenue recognition;
inventory valuation; product warranty reserves; allowance for doubtful accounts; share-based compensation; income taxes including the valuation of deferred tax assets; fair value measurements; valuation of cost method equity investments; valuation
of goodwill; and valuation of long-lived assets.

There have been no significant changes to the Companys significant accounting policies
from those presented in Note 2 Summary of Significant Accounting Policies to the consolidated financial statements included in the Companys Annual Report on Form 10-K filed for its fiscal year ended April 3, 2010.

Certain reclassifications have been made in the accompanying condensed consolidated financial statements for prior periods to conform to the current
presentation. All references to years or quarters relate to fiscal years or fiscal quarters unless otherwise noted.

2. Recent Accounting
Pronouncements

There have been no recent accounting pronouncements or changes in accounting pronouncements during the quarter ended
January 1, 2011 that are of significance to the Company.

3. Restricted Cash

As of January 1, 2011, the Company had restricted cash of $10.8 million, which collateralizes commercial letters of credit substituted for the cash
bond previously held by the Kaohsiung District Court of Taiwan. See Note 17 Legal Proceedings for further discussion.

4. Fair
Value Measurements

Financial Assets Measured at Fair Value

Fair value is defined under Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 820 Fair Value Measurements and Disclosures (ASC Topic 820) as the
exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.
Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. ASC Topic 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair
value. These tiers include the following:



| |  |  | Level 1, defined as observable inputs such as quoted prices in active markets for identical assets or liabilities;
| | - |  | ------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | Level 2, defined as inputs other than quoted prices in active markets for similar assets or liabilities that are either directly or indirectly
observable; and
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------

The Companys fair value hierarchy for its financial assets measured at fair value on a recurring basis as of
January 1, 2011 and April 3, 2010 was as follows (in thousands):

For Level 1 assets, the Company
utilized quoted prices in active markets for identical assets.

For Level 2 assets, exclusive of forward contracts, the Company utilized
quoted prices in active markets for similar assets. For forward contracts, spot prices at December 31, 2010 and April 2, 2010 were utilized to calculate fair values.

The Level 3 assets consisted of auction rate securities and preferred stock acquired through the conversion of certain auction rate securities (ARS). As none of the Companys ARS have traded through
the auction process and limited market transactions have been observed for these securities, estimated fair values were based primarily upon the income approach using a discounted cash flow model which took into account the following: (i) the
underlying structure of each security; (ii) the present value of future principal and interest payments discounted at rates that reflect current market conditions; (iii) consideration of the probabilities of default, restructuring or
redemption by the issuer (trigger events); (iv) estimates of the recovery rates in the event of default for each security; (v) the financial condition, results, ratings of and financial claims on the bond insurers and issuers; and
(vi) the underlying trust assets of the securities.

As of January 1, 2011, the Company held ARS with a total estimated fair value
of $6.2 million. These ARS consisted of $13.7 million par value auction rate securities and $4.0 million par value auction rate securities which were converted by the bond issuer to its preferred stock during the third quarter of 2009. The
contractual maturities of these securities range up to calendar year 2050, and several securities and the preferred stock do not have stated maturities. These securities previously provided short-term liquidity through a Dutch auction process that
reset the applicable interest rate at pre-determined calendar intervals, generally every 28 to 35 days. As a result of the liquidity issues experienced in the global credit and capital markets, the Companys ARS began to experience failed
auctions during fiscal 2008. Since that time, none of the Companys ARS have traded through the auction process, limited market transactions for these securities have been observed, and the credit quality of the counterparties has deteriorated.

##### Table of Contents

As of January 1, 2011, the estimated fair value of the Companys ARS of $6.2 million included $2.5
million of total net unrealized gains. These unrealized gains have been recorded in accumulated other comprehensive income. The Companys ARS are classified as non-current assets on the Condensed Consolidated Balance Sheet at January 1,
2011, consistent with the classification at April 3, 2010.

Subsequent to the third quarter of fiscal 2011, the Company sold a certain
ARS with a par value of $3.0 million for approximately $0.7 million. The Company will record a gain of $0.7 million in the fourth quarter of fiscal 2011 as the security was previously held at zero value. The Company currently continues to receive
all interest payments on its ARS when due, but has not received dividend payments on its preferred stock since the third quarter of 2010. The Company cannot predict if or when its remaining ARS will become liquid or dividend payments on its
preferred stock will resume. See the Companys 2010 Annual Report on Form 10-K for the year ended April 3, 2010 for further information related to these investments.

As of January 1, 2011, the Company had $6.0 million invested in Series D Preferred Stock and $2.2 million invested in
Series E Preferred Stock of OmniGuide, Inc., representing an 11% interest. At each reporting period end, the Company determines whether events or circumstances have occurred that are likely to have a significant adverse effect on the fair value of
these investments. If there are no events or circumstances identified that would adversely affect the fair value of the investments, the fair values of the investments are not calculated as it is not practicable to do so. As of January 1, 2011
and April 3, 2010, management had not identified any events or circumstances that indicated the investments were impaired; therefore, as presented in Note 8 Other Assets, the full carrying value of $8.2 million was included in Other
assets on the Condensed Consolidated Balance Sheets at January 1, 2011 and April 3, 2010, respectively.

During the third quarter of 2011, the Company had no sales of available-for-sale securities. During the third quarter of
2010, the Company had no sales of current available-for-sale securities but sold certain non-current ARS with a par value of $1.9 million pursuant to a tender agreement with the parent company of the securities original issuer. The Company
received approximately $1.4 million on the sale of the ARS, which had an estimated fair value of $1.6 million as of September 26, 2009. As a result of the sale, the Company reclassified $0.3 million of the previously recorded unrealized net
gain out of accumulated other comprehensive income. The unrealized net gain represented the cumulative total of the fair value adjustments related to these ARS prior to the transaction. For purposes of determining gross realized gains and losses and
reclassification out of accumulated other comprehensive income, the cost of securities sold is based on specific identification. Net unrealized holding gains and losses on current available-for-sale securities included in accumulated other
comprehensive income were insignificant as of January 1, 2011 and April 3, 2010.

Underlying maturities of investments at
January 1, 2011 were $123.6 million within one year, $14.6 million between one and five years and $6.2 million beyond ten years.

Net warranty charges incurred include labor charges and costs of replacement parts for system repairs under warranty. These
costs are recorded net of any estimated cost recoveries resulting from either successful repair of damaged parts or from warranties offered by the Companys suppliers for defective components. The provision for warranty charges reflects the
estimate of future anticipated net warranty costs to be incurred for all products under warranty at fiscal year end and is recorded to cost of sales.

11. Deferred Revenue

Generally, revenue is recognized upon fulfillment of acceptance
criteria at the Companys factory and title transfer which frequently occur at the time of delivery to a common carrier. Revenue is deferred whenever title transfer is pending and/or acceptance criteria have not yet been fulfilled. Deferred
revenue occurrences include sales to Japanese customers, shipments of substantially new products and shipments with custom specifications and acceptance criteria. In sales involving multiple element arrangements, the fair value of any undelivered
elements, including installation services, is deferred until the elements are delivered and acceptance criteria are met. Revenue related to maintenance and service contracts is deferred and recognized ratably over the duration of the contracts.

Awards of options, stock-settled stock appreciation rights (SOSARs), unvested restricted stock units (RSUs) and shares
associated with the Companys Employee Stock Purchase Plan (ESPP) representing an additional 3.0 million and 4.6 million shares of stock for the quarters ended January 1, 2011 and January 2, 2010, respectively, were not
included in the calculation of diluted net earnings per share because their effect would have been antidilutive. For the three quarters ended January 1, 2011 and January 2, 2010, awards of options, SOSARs, unvested RSUs and ESPP shares
representing an additional 2.9 million and 4.5 million shares, respectively, were excluded from the calculation of diluted net earnings per share as their effect would have been antidilutive.

15. Share Repurchase Program

On May 15, 2008, the Board of Directors authorized a share repurchase program totaling $20.0 million to acquire shares of the Companys outstanding common stock primarily to offset dilution from
equity compensation programs. The repurchases are to be made at managements discretion in the open market or in privately negotiated transactions in compliance with applicable securities laws and other legal requirements and are subject to
market conditions, share price and other factors. There is no fixed completion date for the repurchase program.

The Company did not
repurchase any shares under this program during the three quarters ended January 1, 2011. As of January 1, 2011, a total of 372,825 shares have been repurchased for $5.3 million under this authorization at an average price of $14.16 per
share, calculated inclusive of commissions and fees. Any cash used to settle repurchase transactions is reflected as a component of cash used in financing activities in the Condensed Consolidated Statements of Cash Flows.

17. Legal Proceedings

Legal Settlement

In 2009, James Dooley, former Chief Executive Officer of the Company,
initiated arbitration against the Company seeking severance in connection with his 2003 termination. On December 10, 2010, the assigned arbitrator ruled in favor of Mr. Dooley. On December 27, 2010, the Company filed a complaint
seeking declaratory relief to vacate the arbitration award with the United States District Court, District of Oregon. At the time of this filing, this proceeding was ongoing and no hearing had been scheduled. Accordingly, we recognized approximately
$1.3 million in settlement and legal costs in the third quarter of fiscal 2011 and a corresponding liability was included in Accrued Liabilities as of January 1, 2011.

All Ring Patent Infringement Prosecution

The Companys proceedings against All Ring
Tech Co., Ltd. (All Ring) in Taiwan for alleged patent infringement are ongoing. As part of these proceedings, the Company was required to post security bonds with the Kaohsiung District Court of Taiwan (Court). In July 2009 and September of 2009,
the Company established letters of credit as a substitution for the security bonds and received back a total of $9.1 million from the Court. The letters of credit are collateralized by a total of $10.8 million of restricted cash, which is included
on the Condensed Consolidated Balance Sheet at January 1, 2011 as a current asset. See the Companys 2010 Annual Report on Form 10-K for the year ended April 3, 2010 and our Quarterly Reports on Form 10-Q for the periods ending
July 3, 2010 and October 2, 2010 for further background related to these proceedings.

18. Restructuring and Cost Management
Plans

As part of the Companys globalization strategy, during the third quarter of fiscal 2011, the Company initiated a restructuring
plan to reduce its worldwide cost structure through transition of certain procurement and manufacturing activities to Asia. As a result of the planned actions, the Company recognized $0.8 million of restructuring costs in the third quarter of 2011
and a corresponding liability was included in Accrued Liabilities as of January 1, 2011.

Additionally, we produce high-capacity test and optical inspection equipment that is critical to the quality
control process during the production of multi-layer ceramic capacitors (MLCCs). Our equipment ensures that each MLCC meets both the electrical and physical tolerances required to perform properly.

Summary of Sequential Quarterly Results

The financial results of the fiscal quarter ended January 1, 2011, which represents the third quarter of 2011, reflected strong demand in key markets
for our products. Total orders were $77.9 million, compared to $70.2 million for the second quarter of 2011, which ended October 2, 2010. The sequential increase in orders was driven primarily by increased orders from our
Interconnect/Micromachining Group (IMG) and Components Group (CG).

Orders for our Semiconductor Group (SG) products decreased approximately
70% in the third quarter of 2011 compared to the prior quarter as customers who had placed multi-unit orders in the first two quarters absorbed capacity.

Orders for our CG products increased approximately 50% compared to the orders in the prior quarter. The increase was primarily due to orders from our MLCC manufacturing customers as they expand capacity
at new facilities. We continue to see high utilization of our test systems by most CG customers.

Orders for our IMG products increased
approximately 75% compared to the prior quarter, driven by strong orders from flex circuit and micromachining customers as they continue to add capacity to support global demand for consumer electronics and mobile devices.

Net sales of $67.2 million for the third quarter of 2011 increased $7.7 million compared to the prior quarter. SG sales increased $16.5 million due to
the fulfillment of backlog orders to memory repair customers as they ramp capacity. Sales for our IMG products decreased $3.3 million primarily due to seasonal declines in deliveries to our flex circuit customers. Sales of our micromachining systems
declined modestly due to timing of demand, partially offset by an increase in our laser ablation tools as a result of demand for a new platform from our New Wave Research (NWR) division. CG sales decreased $5.5 million as customers absorb capacity
expansion from prior quarter deliveries.

Gross margin was 44.7% on net sales of $67.2 million for the third quarter of 2011 compared to 43.7%
on net sales of $59.6 million for the prior quarter. The increase in gross margin percentage was primarily due to the favorable impact of a higher proportion of SG sales.

Net operating expenses of $27.5 million in the third quarter of 2011 increased $2.3 million compared to the prior quarter. This increase was primarily due to $1.3 million of legal settlement costs and
$0.8 million of restructuring costs included in the third quarter of 2011. Excluding these items, net operating expenses increased slightly with higher costs from a full quarter of activity from our Pyrophotonics operations, largely offset by lower
share-based compensation expenses and acquisition-related costs.

Operating income was $2.5 million in the third quarter of 2011, an increase
of $1.8 million compared to $0.7 million in the prior quarter. The improvement was primarily due to higher gross profit, partially offset by legal settlement costs and restructuring charges.

The effective tax rate was 4.7% for the third quarter of 2011, reflecting the benefits from timing of income between quarters and the catch-up benefit from the renewal of the research and development tax
credit.

Net income for the third quarter of 2011 was $2.4 million compared to net loss of $0.6 million in the prior quarter, primarily due to
improved gross profit on higher revenues offsetting the impact of higher net operating expenses.

SG sales in the quarter ended January 1, 2011 increased $19.8 million or 200% compared to the quarter ended
January 2, 2010. The overall increase in sales was due to a rebound in memory repair markets with multi-unit purchases from two of the three largest DRAM manufacturers.

CG sales in the quarter ended January 1, 2011 decreased $2.6 million or 25% compared to the quarter ended January 2, 2010. The decrease was primarily due to normalization of demand from MLCC
customers as compared to the prior year. Sales were higher than usual during the quarter ended January 2, 2010 as a result of demand that had built up during the preceding economic downturn.

IMG sales in the quarter ended January 1, 2011 increased $11.0 million or 58% compared to the quarter ended January 2, 2010. The increase was
primarily driven by solid increases from our flex circuit, micromachining and laser ablation product lines. Demand from our flex circuit and micromachining customers continued to grow as they expand capacities to meet their supply requirements for
smart phones and other mobile electronic devices. The increase of sales of our laser ablation products was driven by demand for the improved features of our new NWR platform.

Gross profit for the quarter ended January 1, 2011 of $30.0 million increased $15.2 million compared to the quarter
ended January 2, 2010, primarily due to higher revenue levels. Gross profit as a percentage of net sales increased to 44.7% for the quarter ended January 1, 2011 from 37.9% for the quarter ended January 2, 2010. This increase was
primarily related to favorable product mix of SG sales, higher revenue levels and increased production capacity utilization.

Selling, Service and Administration

Selling, service and administration (SS&A) expenses primarily consist of labor and other employee-related expenses including share-based compensation expense, travel expenses, professional fees, sales
commissions and facilities costs. SS&A expenses were $15.2 million for the quarter ended January 1, 2011, an increase of $3.3 million compared to the quarter ended January 2, 2010. This increase was primarily attributable to overall
increases in business activity and improved operating results, resulting in increased headcount and higher compensation costs. In addition, various temporary cost reduction measures were in place in fiscal year 2010, including salary reductions,
which have since been restored.

Research, Development and Engineering

Research, development and engineering (RD&E) expenses are primarily comprised of labor and other employee-related expenses, professional fees, project materials, equipment costs and facilities costs.
RD&E expenses totaled $10.2 million for the quarter ended January 1, 2011, an increase of $1.4 million compared to the quarter ended January 2, 2010. This increase was primarily due to increased headcount and compensation expense,
including the restoration of normal pay levels.

Legal Settlement Costs

In 2009, James Dooley, former Chief Executive Officer of the Company, initiated arbitration against us seeking severance in connection with his 2003 termination for cause. On December 10, 2010, the
assigned arbitrator ruled in favor of Mr. Dooley and, as a result, we recognized approximately $1.3 million in settlement and legal costs during the quarter ended January 1, 2011. On December 27, 2010, we filed a complaint
seeking declaratory relief to vacate the arbitration award with the United States District Court, District of Oregon. At the time of this filing, this proceeding was ongoing and no hearing had been scheduled.

Restructuring Costs

As part of the
Companys globalization strategy, during the third quarter of fiscal 2011, we initiated a restructuring plan to reduce our worldwide cost structure through transition of certain procurement and manufacturing activities to Asia. As a result of
these planned actions, we recognized $0.8 million of restructuring costs during the quarter ended January 1, 2011.

Non-operating
Income and Expense

Interest and Other (Expense) Income, net

Interest and other (expense) income, net, consists primarily of interest income, market gains and losses on assets held for our deferred compensation plan, realized and unrealized foreign exchange gains
and losses, bank charges, investment management fees, ARS valuation fees and other miscellaneous non-operating items. Net interest and other expense was insignificant during the quarter ended January 1, 2011 compared to net interest and other
income of $0.4 million for the quarter ended January 2, 2010. The reduction was primarily due to unfavorable foreign currency fluctuations experienced in China and Korea and lower interest yields on our investments.

The income tax provision for the quarter ended January 1, 2011 was $0.1 million on pretax income of $2.5 million, an
effective tax rate of 4.7%. For the quarter ended January 2, 2010, the income tax benefit was $3.1 million on pretax loss of $5.5 million, an effective tax benefit rate of 56.3%. The decrease in the effective tax rate was primarily due to the
timing of income between quarters, the expected level of annual income and the catch-up benefit resulting from the renewal of the research and development tax credit.

Our effective tax rate is subject to fluctuation based upon the mix of income and relative tax rates between jurisdictions, and the occurrence and timing of numerous discrete events such as changes in tax
laws or their interpretations, extensions or expirations of research and experimentation credits, closure of tax years subject to examination, finalization of income tax returns, the relationship of fixed deductions to overall changes in estimated
and actual pretax income or loss and the tax jurisdictions where income or loss is generated. Additionally, our effective tax rate varies widely as income before taxes fluctuates around breakeven points. Based on currently available information, we
are not aware of any further discrete events which are likely to occur that would have a material effect on our financial position, expected cash flows or results of operations. We anticipate no significant changes in unrecognized tax benefits in
the next twelve months as the result of examinations or lapsed statutes of limitation.

$2.4 million, or $0.09 per basic share for the quarter ended January 2, 2010. The improvement was primarily due to improved gross profit on higher revenues in the third quarter of 2011 offsetting the impact of higher net operating expenses.

Net Sales

Net sales were $185.2 million for the first three quarters of 2011, an increase of $95.9 million or 107% compared to net sales of $89.3 million for the first three quarters of 2010. Revenue increased in
each of our product groups, reflecting improved capacity utilization as customers continued to recover from the global economic downturn and improved demand for consumer electronics.

SG sales in the three quarters ended January 1, 2011 increased $39.0 million or 170% compared to the three quarters
ended January 2, 2010. The overall increase in sales was due to improvement in memory markets as customers began to add capacity of memory repair tools in response to higher demand for DRAM memory. In addition, we have seen growth among
LED-scribing and flat panel repair customers as the LED and LCD markets grow.

CG sales in the three quarters ended January 1, 2011 increased $18.3 million or 85% compared to the
three quarters ended January 2, 2010. The increase was primarily due to customer capacity expansion and increased tooling sales as a result of increased utilization levels of our MLCC customers existing systems, in turn driven by
increasing demand for consumer electronics.

IMG sales in the three quarters ended January 1, 2011 increased $38.7 million or 86%
compared to the three quarters ended January 2, 2010. The increase was primarily driven by strong orders from flex-circuit and micromachining customers, a result of increased consumer demand for portable consumer electronics.

Compared to the three quarters ended January 2, 2010, net sales for the three quarters ended January 1, 2011
increased across all geographic regions, but primarily in Asia where net sales increased 133%. The majority of our systems are sold into customers manufacturing facilities in that region.

Gross profit for the three quarters ended January 1, 2011 was $77.5 million, an increase of $47.3 million compared to
gross profit of $30.2 million for the three quarters ended January 2, 2010. Gross profit as a percentage of net sales increased to 41.8% for the three quarters ended January 1, 2011 from 33.8% for the three quarters ended January 2,
2010. These increases were primarily related to higher revenue levels, increased production capacity utilization and favorable product mix.

Selling, Service and Administration

SS&A expenses were $43.1 million for the three quarters ended January 1, 2011, an increase of $7.8 million compared to the three quarters ended January 2, 2010. This increase was primarily
attributable to overall increases in business activity which resulted in increased headcount and higher compensation costs, including an increase in share-based compensation expense of $1.0 million. In addition, various temporary cost reduction
measures were in place in fiscal year 2010, including salary reductions, which have since been restored. These increases in costs were partially offset by acquisition settlement proceeds of $0.9 million received in the first quarter of fiscal 2011.

Research, Development and Engineering

RD&E expenses totaled $30.6 million for the three quarters ended January 1, 2011, an increase of $6.9 million compared to the three quarters ended January 2, 2010. This increase was
primarily due to increased headcount and compensation expense, impacted by the restoration of normal pay levels, and increased project expenses.

Legal Settlement Costs

In 2009, James Dooley, former Chief Executive Officer of the
Company, initiated arbitration against us seeking severance in connection with his 2003 termination for cause. On December 10, 2010, the assigned arbitrator ruled in favor of Mr. Dooley and, as a result, we recognized approximately $1.3
million in settlement and legal costs in the third quarter of fiscal 2011. On December 27, 2010, we filed a complaint seeking declaratory relief to vacate the arbitration award with the United States District Court, District of Oregon. At
the time of this filing, this proceeding was ongoing and no hearing had been scheduled.

Restructuring Costs

As part of the Companys globalization strategy, during the third quarter of fiscal 2011, we initiated a restructuring plan to reduce our worldwide
cost structure through transition of certain procurement and manufacturing activities to Asia. As a result of these planned actions, we recognized $0.8 million of restructuring costs in the third quarter ended January 1, 2011.

Merger Termination Proceeds, net

Net
merger termination proceeds of $4.5 million were recognized in the three quarters ended January 2, 2010, representing the receipt of a $5.4 million merger termination fee offset by $0.9 million of merger transaction costs.

Non-operating Income and Expense

Interest and Other Income, net

Net
interest and other income was $0.2 million for the three quarters ended January 1, 2011 compared to $1.1 million for the three quarters ended January 2, 2010. The reduction was primarily due to unfavorable foreign currency fluctuations
experienced in China and Korea and lower interest yields on our investments.

The income tax benefit for the three quarters ended January 1, 2011 was $0.1 million on pretax income of $1.9 million,
an effective tax rate of 3.9%. For the three quarters ended January 2, 2010, the income tax benefit was $9.1 million on pretax loss of $23.1 million, an effective tax rate of 39.2%. The decrease in the effective tax rate was primarily due to
the relative level of income or loss in each period, the increased tax advantages from growth in our Singapore manufacturing operations, and the recognition of the extended research and development tax credit benefit in the third quarter of fiscal
2011.

Our effective tax rate is subject to fluctuation based upon the mix of income and relative tax rates between jurisdictions, and the
occurrence and timing of numerous discrete events such as changes in tax laws or their interpretations, extensions or expirations of research and experimentation credits, closure of tax years subject to examination, finalization of income tax
returns, the relationship of fixed deductions to overall changes in estimated and actual pretax income or loss and the tax jurisdictions where income or loss is generated. Based on currently available information, we are not aware of any further
discrete events which are likely to occur that would have a material effect on our financial position, expected cash flows or results of operations. We anticipate no significant changes in unrecognized tax benefits in the next twelve months as the
result of examinations or lapsed statutes of limitation.

Net income for the three quarters ended January 1, 2011 was $1.9 million, or $0.07 per basic share, compared to a net
loss of $14.1 million, or $0.51 per basic share for the three quarters ended January 2, 2010. The improvement was primarily due to improved gross profit on higher revenues in the first three quarters of 2011, offsetting the impacts of higher
net operating expenses and income taxes.

Financial Condition and Liquidity

At January 1, 2011, our principal sources of liquidity were cash and cash equivalents of $47.1 million, short-term investments of $104.9 million and accounts receivable of $44.6 million. We also held
$10.8 million in restricted cash as collateral for commercial letters of credit. Our current ratio was 5.3 and we held no long-term debt. Working capital of $242.3 million was down from $253.7 million as of April 3, 2010, primarily as a result
of a $14.6 million shift in investments from short-term to long-term.

In 2008, the Board of Directors authorized a share repurchase program
totaling $20.0 million to acquire shares of our outstanding common stock primarily to offset dilution from equity compensation programs. Repurchases under the program are to be made at managements discretion in the open market or in privately
negotiated transactions in compliance with applicable securities laws and other legal requirements and are subject to market conditions, share price and other factors. We did not repurchase any shares under this program during the three quarters
ended January 1, 2011. As of January 1, 2011, a total of 372,825 shares have been repurchased under this authorization for $5.3 million and an average price of $14.16 per share, calculated inclusive of commissions and fees. Cash used to
settle repurchase transactions is reflected as a component of cash used in financing activities in the Condensed Consolidated Statements of Cash Flows. There is no fixed completion date for the repurchase program.

As of January 1, 2011, we held a total of $13.7 million invested in auction rate securities (ARS) at par value. Additionally, we held $4.0 million
of par value ARS which were converted by the bond issuer to its preferred stock during the third quarter of 2009. These securities were recorded at an estimated fair value of $6.2 million as of January 1, 2011. The contractual maturities of
these securities range up to calendar year 2050, and several securities and the preferred stock do not have stated maturities.

We currently
continue to receive all interest payments on our ARS when due, but have not received dividend payments on our preferred stock since the third quarter of 2010. Although we sold a certain ARS with a par value of $3.0 million for approximately $0.7
million subsequent to the third quarter of fiscal 2011, we cannot predict if or when our remaining ARS will become liquid or dividend payments on our preferred stock will resume.

Sources and Uses of Cash for the Three Quarters Ended January 1, 2011

Net cash flows
provided by operating activities totaled $21.3 million for the three quarters ended January 1, 2011 due to $14.4 million from net income and non-cash items and $6.9 million from net changes within working capital. The primary sources of cash
from working capital consisted of $13.6 million from increases in accounts payable and accrued liabilities and $0.5 million from decreases in other current assets, partially offset by increases in trade receivables of $5.9 million, decreases in
deferred revenue of $0.8 million and increases in shipped systems pending acceptance of $0.6 million.

For the three quarters ended
January 1, 2011, net cash used in investing activities of $15.5 million primarily resulted from the acquisition of the assets of PyroPhotonics Lasers, Inc. for $8.1 million, purchases of property, plant and equipment of $4.4 million and net
purchases of investments of $3.4 million. Net cash provided by financing activities of $0.8 million was due to proceeds from stock plan activity.

PART II  OTHER INFORMATION

Item 1.     Legal Proceedings

Legal Settlement

In 2009, James Dooley,
our former Chief Executive Officer, initiated arbitration against us seeking severance in connection with his 2003 termination for cause. On December 10, 2010, the arbitrator ruled that, despite having pled guilty to violating federal
securities laws by willfully and knowingly making false statements to the Companys accountants, Dooleys actions did not satisfy the definition of cause under his employment agreement. As a result, the arbitrator determined that
Dooley is entitled to severance benefits under his employment agreement, plus interest from June 2005. This proceeding was subject to binding arbitration under the terms of the employment agreement. Accordingly, we recognized approximately $1.3
million in settlement and legal costs in the third quarter of fiscal 2011. On December 27, 2010, we filed a complaint seeking declaratory relief to vacate the arbitration award with the United States District Court, District of Oregon. At
the time of this filing, this proceeding was ongoing and no hearing had been scheduled.

equipment market for semiconductor and micro-electronics manufacturers has historically been characterized by sudden and severe cyclical variations in product supply and demand due to a number of factors including capacity utilization, demand for
customers products, inventory levels relative to demand, and access to affordable capital. The timing, severity and duration of these market cycles are difficult or impossible to predict. Significant downturns in the market for semiconductor
and micro-electronics used in electronic devices reduce demand for our products and may materially and adversely affect our business, financial condition and operating results.

For example, the recent economic slowdown resulted in a decrease in orders for all of our product groups for each quarter throughout 2009, with virtually no orders for our memory repair systems throughout
fiscal 2010. Additionally, some of our customers ability to access credit was adversely affected, limiting their ability to purchase our products. The degree of the impact on our business of the current economic environment will continue to
depend on a number of factors, including the strength and continuity of the recovery in the US economy, the global economy in general, access to capital and stability of the financial system, and overall health of the semiconductor and
micro-electronics industries. This impact may cause potential material adverse changes to our financial and operational results.

To meet
rapidly changing demand in the industries we serve, we must effectively manage our resources and production capacity. During periods of decreasing demand for our products, we must be able to appropriately align our cost structure with prevailing
market conditions and effectively manage our supply chain. Our ability to rapidly and effectively reduce our cost structure in response to such downturns is limited by the fixed nature of many of our expenses in the near term and by our need to
continue our investment in next-generation product technology and to support and service our products. Conversely, when upturns in this market occur, we may have difficulty rapidly and effectively increasing our manufacturing capacity or procuring
sufficient materials to meet sudden increases in customer demand, which could result in the loss of business to our competitors and harm to our relationships with our customers. If we are not able to timely and appropriately adapt to changes in our
business environment, our business, financial condition or results of operations may be materially and adversely affected.

The markets
in which we operate are highly competitive.

We face substantial competition from established competitors throughout the world, some of
which have greater financial, engineering, manufacturing and marketing resources than we do. Those competitors with greater resources may, in addition to other things, be able to better withstand periodic downturns, compete more effectively on the
basis of price and technology, or more quickly develop enhancements to, and new generations of, products that compete with the products we manufacture and market. New companies may enter the markets in which we compete, or industry consolidation may
occur, further increasing competition in those markets. Furthermore, our technological advantages may be reduced or lost as a result of technological advances by our competitors.

Moreover, our business, financial condition or results of operations may be materially and adversely
affected by competitive pressure and intense price-based competition. We have experienced and continue to experience significant price competition in the sale of our products. In addition, pricing pressures typically have become more intense during
cyclical downturns when competitors seek to maintain or increase market share, reduce inventory or introduce more technologically advanced products. We believe that to be competitive we must continue to expend significant financial resources in
order to, among other things, invest in new product development and enhancements. We may not be able to compete successfully in the future and increased competition may result in price reductions, reduced profit margins and loss of market share.

Our operating results may fluctuate significantly from period to period, which could negatively impact our business.

Our revenues, operating margins and other operating results could fluctuate significantly from quarter to quarter depending upon a
variety of factors, including:



| |  |  | demand for our products as a result of the cyclical nature of the semiconductor and micro-electronics manufacturing industries and the markets upon
which they depend or otherwise;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in the timing and terms of product orders by our customers as a result of our customer concentration or otherwise;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | changes in the mix of products and services that we offer;
| | - |  | ----------------------------------------------------------



| |  |  | timing and market acceptance of our new product introductions;
| | - |  | --------------------------------------------------------------



| |  |  | delays or problems in the planned introduction of new products, or in the performance of any such products following delivery to customers;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our competitors announcements of new products, services or technological innovations, which can, among other things, render our products less
competitive due to the rapid technological change in our industry;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the timing and related costs of any acquisitions, divestitures or other strategic transactions;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | our ability to reduce our costs in response to decreased demand for our products and services;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | disruptions in our manufacturing process or in the supply of components to us;
| | - |  | ------------------------------------------------------------------------------



| |  |  | write-offs for excess or obsolete inventory; and
| | - |  | ------------------------------------------------



| |  |  | competitive pricing pressures.
| | - |  | ------------------------------

These risks may be exacerbated by the fact that we derive a substantial portion of our revenue from the sale of a relatively small numbers of products. As a result of these risks, we believe that quarter
to quarter comparisons of our revenue and operating results may not be meaningful, and that these comparisons may not be an accurate indicator of our future performance.

Our markets are subject to rapid technological change, and to compete effectively, we must continually introduce new products that achieve market acceptance.

The markets for our products are characterized by rapid technological change and innovation, frequent new product introductions, changes in customer
requirements and evolving industry standards. Our future performance will depend on the successful development, introduction and market acceptance of new and enhanced products that address technological changes and the requirements of current and
potential customers. The development of new, technologically advanced products is a complex and uncertain process, requiring high levels of innovation and highly skilled engineering and development personnel, as well as the accurate anticipation of
technological and market trends. We cannot assure you that we will be able to identify, develop, manufacture, market or support new or enhanced products successfully, if at all, or on a timely basis. The introduction by us or by our competitors of
new or enhanced products, or alternative technologies, may cause our customers to defer, change or cancel orders for our existing products or cease purchasing our products altogether. For example, for many years the semi-conductor memory industry
has employed alternative redundancy technologies. The adoption by our customers of electrical redundancy technology could have a material adverse effect on demand for our Semiconductor Group (SG) products. Further, we cannot assure that our new
products will gain market acceptance or that we will be able to respond effectively to product announcements by competitors, technology changes or emerging industry standards. If we are unable to develop new or enhanced products to address product
or technology changes or new industry standards on a timely basis or at all, or if our new or enhanced products are not accepted by the market, our business, results of operations and financial condition may be adversely affected.

We depend on a few significant customers, none of which are bound by long-term contracts, for a large
portion of our revenues.

We depend on a few significant customers for a large portion of our revenues. In fiscal 2010, our top ten
customers accounted for approximately 56% of total net sales, with one customer accounting for approximately 30% of total net sales. We anticipate that sales of our products to a relatively small number of customers will continue to account for a
significant portion of our revenues. Consolidation between customers, changes in various partnership and technology arrangements between customers, customer bankruptcies or customer departures from their respective industries all may result in even
fewer customers accounting for a high percentage of our revenue. For example, in early calendar 2009 Qimonda AG, historically one of our top European customers, went bankrupt.

None of our customers have any long-term obligation to continue to buy our products or services. As a result, our customers may delay, reduce or cease ordering our products or services at any time.
Cancellations, reductions or deferrals could result from a number of factors, including a prolonged or additional downturn in the semiconductor or micro-electronics industries, manufacturing delays, completion of new product manufacturing ramp-up by
customers, quality or reliability issues with our products, the development and introduction of new products and technologies by our competitors, or interruptions to our customers operations due to fire, natural disasters or other events. In
particular, the markets we serve are subject to significant and unpredictable volatility, and downturns in those markets reduce demand for our products. In the future, the cancellation, reduction or deferral of purchases of our products by even a
single customer could significantly reduce our revenues in any particular quarter. If we were to lose any of our significant customers or suffer a material reduction in their purchase orders, revenue could decline and our business, financial
condition and results of operations could be materially and adversely affected.

The failure of critical suppliers to deliver sufficient
product quantities in a timely and cost-effective manner could negatively affect our business.

We use a wide range of materials from
numerous suppliers in the manufacture of our products, including custom electronic, laser and mechanical components. We generally do not have guaranteed supply arrangements with our suppliers. We seek to reduce the risk of production and service
interruptions and shortages of key parts by selecting and qualifying alternative suppliers for key parts, monitoring the financial stability of key suppliers and maintaining appropriate inventories of key parts. Although we make reasonable efforts
to ensure that parts are available from multiple suppliers, some key parts are available only from a single supplier or a limited group of suppliers in the short term. In addition, some of the lasers we use in our products are difficult to
manufacture, and as a result we may not receive an adequate supply of lasers in a timely fashion to fill orders. Operations at our suppliers facilities are subject to disruption or discontinuation for a variety of reasons, including changes in
business relationships, competitive factors, financial difficulties, work stoppages, fire, natural disasters or other causes. Any such disruption or discontinuation to our suppliers operations could interrupt or reduce our manufacturing
activities and delay delivery of our products, any or all of which could materially and adversely affect our results of operations. In addition, as markets recover, there is a heightened risk that one or more of our suppliers may not be able to meet
increased demand requirements, adversely impacting our ability to fulfill orders and win business with our customers.

The failure of
our contract manufacturers to timely perform could negatively affect our business.

We have arrangements with contract manufacturers to
complete the manufacture of certain of our products or product subcomponents. Any significant interruption in our contract manufacturers ability to provide manufacturing services to us as a result of contractual disputes with us or another
party, labor disruptions, financial difficulties, natural disasters, delay or interruption in the receipt of inventory or other causes could result in reduced manufacturing capabilities or delayed deliveries for certain of our products, any or all
of which could materially and adversely affect our results of operations.

We may recognize charges for excess or obsolete inventory if our demand projections are incorrect or
our technology strategy changes.

Our business is highly competitive and one factor on which we compete is the ability to ship products
on schedules required by customers. In order to facilitate timely shipping, management forecasts demand, both in type and amount of products, and these forecasts are used to determine inventory to be purchased. We also order materials based on our
technology roadmap, which represents managements assessment of technology that will be utilized in new products that we develop. Certain types of inventory, including lasers and optical equipment, are particularly expensive and may only be
used in the production of a single type of product. If actual demand is lower than forecast with respect to the type or amount of products actually ordered, or both, our inventory levels may increase. For example, at January 1, 2011, we had
$70.2 million of inventory reflected on our Condensed Consolidated Balance Sheet, much of which we purchased or committed to purchase prior to the time the severity of the recent economic downturn became apparent. As a result, there is a risk that
we may have to incur material accounting charges for excess and obsolete inventory if inventory cannot be used, which would negatively affect our financial results. Also, if we alter our technology or product development strategy, we may have
inventory which may not be usable under the new strategy, which may also result in material accounting charges. For example, during fiscal 2009, we wrote-off $4.1 million of material from a research, development and engineering program due to a
change in our product development strategy.

We may not be able to protect the proprietary rights upon which our business depends.

Our success depends significantly upon the protection of our proprietary rights. We attempt to protect our proprietary rights through
patents, copyrights, trademarks, maintenance of trade secrets and other measures, including entering into confidentiality agreements. We incur substantial costs to obtain and maintain patents and to defend our intellectual property rights. For
example, we initiated litigation against All Ring Tech Co., Ltd. in Taiwan in August 2005 alleging that certain of our patent rights had been violated. We rely upon the laws of the United States and foreign countries where we develop, manufacture or
sell our products to protect our proprietary rights. We may not be successful in protecting these proprietary rights, these rights may not provide the competitive advantages that we expect, or other parties may challenge, invalidate or circumvent
these rights.

Further, our efforts to protect our intellectual property may be less effective in some foreign countries where intellectual
property rights are not as well protected as in the United States. Many United States companies have encountered substantial problems in protecting their proprietary rights against infringement in foreign countries. If we fail to adequately protect
our intellectual property in these countries, it could be easier for our competitors to sell competing products in foreign countries, which could result in reduced sales and gross margins.

We may be subject to claims of intellectual property infringement.

Several of our
competitors hold patents covering a variety of technologies, applications and methods of use similar to some of those used in our products. While we attempt in our designs to avoid patent infringement, from time to time we and our customers have
received correspondence from our competitors claiming that some of our products, as used by our customers, may be infringing one or more of these patents. Competitors or others have in the past and may in the future assert infringement claims
against our customers or us with respect to current or future products or uses, and these assertions may result in costly litigation or require us to obtain a license to use intellectual property rights of others. If claims of infringement are
asserted against our customers, those customers may seek indemnification from us for damages or expenses they incur.

If we become subject to
infringement claims, we will evaluate our position and consider the available alternatives, which may include seeking licenses to use the technology in question or defending our position. These licenses, however, may not be available on satisfactory
terms or at all. If we are not able to negotiate the necessary licenses on commercially reasonable terms or successfully defend our position, our financial condition and results of operations could be materially and adversely affected.

Our ability to reduce costs is limited by our need to invest in research and development.

Our industry is characterized by the need for continued investment in research and development. Because of intense competition in the industries in which
we compete, if we were to fail to invest sufficiently in research and development, our products could become less attractive to our current and potential customers or obsolete, and our business and financial condition could be materially and
adversely affected. As a result of our need to maintain our spending levels in this area, our operating results could be materially harmed if our net sales decline.

In addition, as a result of our emphasis on research and development and technological innovation, our
operating costs may increase in the future, and research and development expenses may increase as a percentage of total operating expenses and as a percentage of net sales.

We have made acquisitions and may make additional acquisitions in the future, which may be difficult to integrate, disrupt our business, dilute shareholder value or divert management attention.

We may make acquisitions of, or significant investments in, other businesses with complementary products, services or technologies,
such as our September 2010 acquisition of the assets of PyroPhotonics Lasers, Inc. Acquisitions involve numerous risks, many of which are unpredictable and beyond our control, including:



| |  |  | difficulties and increased costs in connection with integration of the personnel, operations, technologies and products of the merged businesses;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | implementation of our enterprise resource planning (ERP) system into the acquired companys operations;
| | - |  | -------------------------------------------------------------------------------------------------------



| |  |  | diversion of managements attention from other operational matters;
| | - |  | -------------------------------------------------------------------



| |  |  | the potential loss of key employees of the acquired company;
| | - |  | ------------------------------------------------------------



| |  |  | lack of synergy or inability to realize expected synergies resulting from the acquisition;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | acquired assets becoming impaired as a result of technological advancements or worse-than-expected performance by the acquired company;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------



| |  |  | difficulties establishing satisfactory internal controls at the acquired company;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | risks and uncertainties relating to the performance of the combined company following the transaction; and
| | - |  | ----------------------------------------------------------------------------------------------------------



| |  |  | incurring unanticipated liabilities for which we will not be indemnified.
| | - |  | -------------------------------------------------------------------------

Furthermore, the accounting for an acquisition could result in significant charges resulting from amortization of intangible assets we acquire. Our inability to effectively manage these risks could result
in our inability to realize the anticipated benefits of an acquisition on a timely basis, or at all, and materially and adversely affect our business, financial condition and results of operations. In addition, all acquisition transaction costs must
be expensed as incurred rather than capitalized, which may have a material adverse effect on our results of operations.

The means by which we
finance an acquisition may also significantly affect our business or the value of the shares of our common stock. If we issue common stock to pay for an acquisition, the ownership percentage of our existing shareholders will be reduced and the value
of the shares held by our existing shareholders could be diluted. If we use cash on hand to pay for an acquisition, the payment could significantly reduce the cash that would be available to fund our operations or to use for other purposes. If we
borrow funds in connection with an acquisition, we would be required to use cash to service the debt and to comply with financial and other covenants.

We may from time to time also make strategic investments in development stage companies. Investments in development stage companies are subject to a high degree of risk. We cannot assure you that we will
not lose all or a portion of our investment in any such company.

We are implementing our globalization strategy, and if we do not
effectively implement a globalization plan or if we decide to change our strategy, our operating results could be negatively impacted.

We are implementing our globalization strategy in which we are moving certain operational resources and capabilities to different countries in Asia to
reduce costs and to be closer to our customers. We believe this strategy will reduce our manufacturing costs for certain products, enhance customer relationships and improve our responsiveness. We opened a manufacturing facility in Singapore in the
fourth quarter of 2010 for certain IMG and CG products.

Our globalization strategy is subject to a variety of complexities and risks, many of
which we have little experience managing, and which may divert a substantial amount of managements time. These risks include:



| |  |  | challenges in designing new facilities that can be scaled for future expansion, replicating current processes and bringing new facilities up to full
operation;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | unpredictable costs, redundancy costs and cost overruns for developing new facilities and acquiring equipment;
| | - |  | --------------------------------------------------------------------------------------------------------------

| |  |  | building local management teams, technical personnel and other staff for functions that we have not previously conducted outside of the United States;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | technical obstacles such as poor production or process yield and loss of quality control during the ramp of a new facility;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | requalifications and other procedures that may be required by our customers;

| |  |  | rapidly changing business conditions that may require plans to be changed or abandoned before they are fully implemented; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | challenges posed by distance and by differences in language and culture.
| | - |  | ------------------------------------------------------------------------

These and other factors could delay the development and implementation of our strategy, as well as impair our gross margins, delay shipments and deliveries, cause us to lose sales, require us to write off
investments already made, damage our reputation and harm our business, financial condition and operating results. If we decide to change our current global regionalization strategy, we may incur charges for certain costs incurred.

We are exposed to the risks of operating a global business, including risks associated with exchange rate fluctuations, legal and regulatory
changes and the impact of regional and global economic disruptions.

International shipments accounted for 90% of net sales in 2010,
with 83% of our net sales to customers in Asia. We expect that international shipments will continue to represent a significant percentage of net sales in the future. We also have significant foreign operations, including a Singapore manufacturing
facility, research and development facilities in Taiwan and China, and sales and service offices in various countries. Under our globalization strategy, we intend to increase our foreign operations in the future. Our non-U.S. sales, purchases and
operations are subject to risks inherent in conducting business abroad, many of which are outside our control, including the following:



| |  |  | periodic local or geographic economic downturns and unstable political conditions;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | price and currency exchange controls;
| | - |  | -------------------------------------



| |  |  | fluctuation in the relative values of currencies;
| | - |  | -------------------------------------------------



| |  |  | difficulty in repatriating money, whether as a result of tax laws or otherwise;
| | - |  | -------------------------------------------------------------------------------



| |  |  | difficulties protecting intellectual property;
| | - |  | ----------------------------------------------



| |  |  | compliance with labor laws and other laws governing employees;
| | - |  | --------------------------------------------------------------



| |  |  | local labor disputes;
| | - |  | ---------------------



| |  |  | shipping delays and disruptions;
| | - |  | --------------------------------



| |  |  | increases in shipping costs, caused by increased fuel costs or otherwise, which we may not be able to pass on to our customers;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | unexpected changes in trading policies, regulatory requirements, tariffs and other barriers; and
| | - |  | ------------------------------------------------------------------------------------------------



| |  |  | difficulties in managing a global enterprise, including staffing, collecting accounts receivable, managing suppliers, distributors and representatives,
and repatriating earnings.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our business and operating results could also be impacted, directly or indirectly, by natural
disasters, outbreaks of infectious disease, military action, international conflicts, terrorist activities, civil unrest and associated political instability. Any such events or circumstances may result in heightened security concerns with respect
to domestic and international travel and commerce, which may further affect our business and operating results. In particular, due to these uncertainties, we are subject to the following additional risks:



| |  |  | future tightening of immigration controls may adversely affect the residence status of non-U.S. engineers and other key technical employees in our U.S.
facilities or our ability to hire new non-U.S. employees in such facilities;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | more frequent instances of shipping delays;
| | - |  | -------------------------------------------



| |  |  | demand for our products may not increase or may decrease; and
| | - |  | -------------------------------------------------------------



| |  |  | our customers or suppliers may experience financial difficulties or cease operations.
| | - |  | -------------------------------------------------------------------------------------

Unfavorable currency exchange rate fluctuations may lead to lower operating margins or may cause us to raise prices.

Currency exchange rate fluctuations could have an adverse effect on our sales and results of operations and we could experience losses with respect to
forward exchange contracts into which we may enter. Unfavorable currency fluctuations could require us to increase prices to foreign customers, which could result in lower net sales by us to such customers. Alternatively, if we do not adjust the
prices for our products in response to



27



---

##### Table of Contents

unfavorable currency fluctuations, our results of operations could be materially and adversely affected. In addition, many of our foreign sales are denominated in the currency of the country in
which these products are sold and the currency we receive in payment for such sales could be less valuable at the time of receipt as a result of exchange rate fluctuations. From time to time, we enter into forward exchange contracts to hedge the
value of accounts receivable primarily denominated in Japanese yen and other currencies. However, we cannot be certain that our efforts will be adequate to protect us against significant currency fluctuations or that such efforts will not expose us
to additional exchange rate risks, which could adversely affect our results of operations.

Our effective tax rate is subject to
fluctuation and we may have exposure to additional tax liabilities.

As a global company, we are subject to taxation in the United
States and numerous foreign jurisdictions. Our effective tax rate is subject to fluctuation from one period to the next because the income tax rates for each year are a function of many factors, including: (a) taxable income levels and the
effects of a mix of profits (losses) earned by ESI and our subsidiaries in numerous tax jurisdictions with a broad range of income tax rates, (b) our ability to utilize deferred tax assets, (c) taxes, refunds, interest or penalties
resulting from tax audits, (d) the magnitude of various credits and deductions as a percentage of total taxable income and (e) changes in tax laws or the interpretation of such tax laws. Changes in the mix of these items may cause our
effective tax rate to fluctuate between periods, which could have a material adverse effect on our financial position and results of operations.

Furthermore, we are periodically under audits by United States and foreign tax authorities. We may have exposure to additional tax liabilities as a result of these audits. Significant judgment is required
in determining our provision for income and other tax liabilities. Although we believe our tax estimates are reasonable, the final outcome of tax audits and the impact of changes in tax laws or the interpretation of tax laws could result in material
differences from what is reflected in historical income tax accruals. If additional taxes are assessed as a result of an examination, a material effect on our financial results, tax positions or cash flows could occur in the period or periods in
which the determination is made.

No significant market currently exists for the auction rate securities we hold and we may not be able
to liquidate them at the current valuation, if at all, and we may recognize impairment charges if their estimated fair values decline.

As of January 1, 2011, we held a total of $13.7 million invested in auction rate securities (ARS) at par value. Additionally, we held $4.0 million of
par value ARS which were converted by the bond issuer to its preferred stock during the third quarter of 2009. These securities were recorded at an estimated fair value of $6.2 million as of January 1, 2011. The contractual maturities of these
securities range up to calendar year 2050, and several securities and the preferred stock do not have stated maturities. As a result of disruptions experienced in the global credit and capital markets, the auctions that previously provided liquidity
for the ARS began to fail during the second fiscal quarter of 2008.

Since that time, none of these securities have traded through the auction
process, and although we sold a certain ARS with a par value of $3.0 million for approximately $0.7 million subsequent to the third quarter of fiscal 2011, limited market transactions for these securities have been observed. Additionally, the bond
insurers that guarantee the ARS experienced credit rating downgrades and the issuer of the preferred stock suspended dividend payments. Consequently, we recognized significant write downs of the ARS as a result of the declines in fair value and the
ARS are categorized as non-current assets.

We cannot reasonably predict if or when our remaining ARS will become liquid, and it is not
possible to ascertain when or whether market conditions will change resulting in the recovery of fair value on these auction rate securities. It is possible that a secondary market for the underlying securities will develop in which trading prices
fall below our currently recorded fair values. Under such a scenario, or if other events arise that impact the fair value of the securities, we may have to recognize further losses, which would adversely impact our financial position and results of
operations.

It is possible that changes in the credit markets could also impact the liquidity of our investments and cash equivalents, which
could impair our liquidity or require us to recognize impairment charges on the value of those investments, which would negatively impact our financial position and results of operations.

Our intangible assets may become impaired.

We held a total of $14.5 million in acquired intangible assets (See Note 7 Acquired Intangible Assets) and goodwill at January 1,
2011. We review our acquired intangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. We test goodwill for impairment at least annually. If such an adverse event occurred and had
the effect of changing one of the critical assumptions or estimates related to the fair value of our intangible assets or goodwill, an impairment charge could result. For example, during fiscal 2009, as a result of a decrease in our market
capitalization, we recorded a goodwill impairment charge of $17.4 million to write off all existing goodwill. Any such impairment charges may have a material negative impact on our financial condition and operating results.

We may be unable to retain, attract and assimilate key managerial, financial, engineering and other technical personnel.

Our continued success depends in part upon the services of our key managerial, financial and technical personnel. The loss of key personnel, or our
inability to attract, assimilate and retain qualified personnel, could result in the loss of customers, inhibit our ability to operate and grow our business, and otherwise have a material adverse effect on our business and results of operations. We
have previously had to, and may in the future have to, impose salary reductions on senior employees during economic downturns in an effort to maintain our financial position. These actions may have an adverse effect on employee loyalty and may make
it more difficult for us to attract and retain key personnel. Competition for qualified personnel in the industries in which we compete is intense, and we may not be successful in attracting and retaining qualified personnel. We may incur
significant costs in our efforts to recruit and retain key personnel, which could affect our financial position and results of operations.

We are exposed to lawsuits in connection with our business and operations.

From time to time we are subject to various legal proceedings, including claims that involve possible infringement of patent or other intellectual property rights of third parties. It is inherently
difficult to assess the outcome of litigation matters, and there can be no assurance that we will prevail in any litigation. For example, in December 2010, an arbitrator ruled that James Dooley, our former Chief Executive Officer, is entitled to
severance in connection with his 2003 termination for cause. Although we are contesting this decision, we recorded approximately $1.3 million in settlement and legal costs in the third quarter of fiscal 2011. Any such litigation could result in
substantial cost and diversion of managements attention, which by itself could have a material adverse effect on our financial condition and operating results. Further, adverse determinations in such litigation could result in loss of our
property rights, subject us to significant liabilities, require us to seek licenses from others or prevent us from manufacturing or selling our products, any of which could materially adversely affect our business, financial condition, results of
operations or cash flows.

Many of our products are highly complex and may contain defects or errors.

Our products are highly complex, and our extensive product development, manufacturing and testing processes may not be adequate to detect all defects,
errors, failures and quality issues that could impact customer satisfaction or result in claims against us. As a result, we may have to replace certain components or provide remediation in response to the discovery of defects in products after they
are shipped. The occurrence of any defects, errors, failures or quality issues could result in cancellation of orders, product returns, diversion of our resources, legal actions by our customers and other losses to us or to our customers. These
occurrences could also result in the loss of, or delay in, market acceptance of our products and loss of sales, which would harm our business and adversely affect our revenues and profitability.

Our stock price is volatile.

The
market price of our common stock has fluctuated widely. During fiscal 2010, our stock price fluctuated between a high of $14.36 per share and a low of $5.92 per share. Consequently, the current market price of our common stock may not be indicative
of future market prices, and we may be unable to sustain or increase the value of an investment in our common stock. Factors affecting our stock price, many of which our outside of our control, may include:



| |  |  | variations in operating results from quarter to quarter;
| | - |  | --------------------------------------------------------



| |  |  | changes in earnings estimates by analysts or our failure to meet analysts expectations;

| |  |  | political changes, hostilities or natural disasters;

In addition, the stock market has recently experienced significant price and volume fluctuations. These fluctuations have particularly affected the market prices of the securities of high-technology
companies like ours. These market fluctuations could adversely affect the market price of our common stock.

Provisions of our charter
documents, our shareholder rights plan and Oregon law could make it more difficult for a third party to acquire us.

Our articles of
incorporation and bylaws contain provisions that could make it harder for a third party to acquire us without the consent of our Board of Directors. Our Board of Directors has also adopted a shareholder rights plan, or poison pill, which
would significantly dilute the ownership of a hostile acquirer. In addition, the Oregon Control Share Act and the Oregon Business Combination Act limit the ability of parties who acquire a significant amount of voting stock to exercise control over
us. These provisions may have the effect of lengthening the time required for a person to acquire control of us through a proxy contest or the election of a majority of our Board of Directors, may deter efforts to obtain control of us and may make
it more difficult for a third party to acquire us without negotiation. These provisions may apply even if the offer may be considered beneficial by our shareholders.
