NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

1. BASIS OF PRESENTATION

Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to the Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. The interim financial information is unaudited and does not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting only of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the quarter ended April 1, 2006 are not necessarily indicative of the results that may be expected for the year ending December 31, 2006. For further information, refer to the consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2005.

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the related disclosures of contingent assets and liabilities. We evaluate our estimates on an ongoing basis, including those related to revenue recognition, allowance for doubtful accounts, inventory valuation, deferred tax assets, property and equipment, goodwill and other intangible assets, warranty obligations, restructuring and impairment charges, contingencies and litigation, and stock-based compensation. We base our estimates on historical experience and on other assumptions that are believed to be reasonable under current 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. Our intent is to accurately state our assets given facts known at the time of valuation. Our assumptions may prove incorrect as facts change in the future. Actual results may differ from these estimates under different assumptions or conditions.

The accompanying condensed consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries after the elimination of all significant intercompany account balances and transactions.

Allowance for Doubtful Accounts

We evaluate our allowance for doubtful accounts based on a combination of factors. In circumstances where we are aware of a specific customer’s inability to meet its financial obligations, we provide a specific allowance for bad debt against the amount due to reduce the net recognized receivable to the amount we reasonably believe will be collected. We charge accounts receivable balances against our allowance for doubtful accounts once we have concluded our collection efforts. We maintained an allowance for doubtful accounts of $1.2 million and $1.0 million at April 1, 2006 and December 31, 2005, respectively.

Forward Foreign Exchange Contracts

We enter into forward foreign exchange contracts to buy and sell foreign currencies to hedge the parent’s intercompany balances denominated in a currency other than the U.S. dollar. The maturities of these instruments are generally less than 12 months. In 2006 and 2005, these hedging contracts were denominated primarily in the Taiwanese Dollar, Singapore Dollar, the Euro and the Japanese Yen. The effect of exchange rate changes on forward exchange contracts is expected to offset the effect of exchange rate changes on the underlying hedged items. We believe these financial instruments do not subject us to speculative risk that would otherwise result from changes in currency exchange rates. The gain (loss) recognized in other income, net related to these transactions was $0.9 million and ($1.2) million during the quarters ended April 1, 2006 and April 2, 2005, respectively. The unrealized gain or loss on these contracts is recorded on the balance sheet at the end of each reporting period as derivative assets or liabilities and the change in value during the period is recorded in other income, net on our condensed consolidated statements of operations.

We also enter into forward exchange contracts to buy and sell foreign currencies to hedge certain forecasted intercompany transactions, which represent foreign currency risk. These intercompany transactions consist of forecasted charges to our international subsidiaries for the purchase of inventories, which are subsequently resold to third party customers. The intercompany charges are denominated in U.S. dollars, while the third party sales are denominated primarily in Japanese Yen. We expect the hedge of these forecasted transactions to be highly effective in offsetting potential changes to cash flows attributed to fluctuating exchange rates. For these derivatives, the gain or loss from the effective portion of the hedge is reported as a component of accumulated other

6

comprehensive income (loss) and is reclassified into earnings in the period in which the hedged transaction affects earnings, and within the same income statement line item as the impact of the hedged transaction. Any gain or loss from the ineffective portion of the hedge in excess of the cumulative change in the present value of future cash flows of the hedged item and any amounts excluded from the assessment of hedge effectiveness are recognized as a component of cost of sales during the period of change. As of April 1, 2006, the gains, net of losses, recorded to accumulated other comprehensive income (loss) were less than $0.1 million. For the quarter ended April 1, 2006 we recorded gains, net of losses, of $0.6 million for the ineffective portion of these hedges within cost of sales.

Recent Accounting Pronouncements

In December 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 123(R), “Share-Based Payment,” or SFAS 123(R). SFAS 123(R) requires the Company to measure all employee stock-based compensation awards using a fair value method and record such expense in its consolidated financial statements. In March 2005, the SEC issued Staff Accounting Bulletin 107, which provides the Staff’s views regarding interactions between SFAS 123(R) and certain SEC rules and regulations and provides interpretations of the valuation of share-based payments for public companies. The adoption of SFAS 123(R) requires additional accounting related to the income tax effects and additional disclosure regarding the cash flow effects resulting from share-based payment arrangements. The adoption of SFAS 123(R) in the quarter ended April 1, 2006, had a material impact on the Company’s consolidated results of operations, financial position and statement of cash flows. For more information on stock-based compensation costs during the quarter ended April 1, 2006, refer to Note 3, “Stock-Based Compensation.”

In December 2004, the FASB issued SFAS No. 151, “Inventory Costs, an amendment of ARB No. 43, Chapter 4,” or SFAS 151. The standard clarifies that certain abnormal amounts be expensed as incurred, rather than included as a cost of inventory. SFAS 151 also requires that the allocation of fixed overhead costs to inventory be based upon a normal production capacity. The Company adopted the standard effective January 1, 2006, which resulted in an increased carrying value of inventory and decreased cost of sales of approximately $1.6 million, net of tax, or $0.01 per diluted share for the quarter ended April 1, 2006.

2. NET INCOME PER SHARE

Basic net income per share is computed by dividing net income by the weighted-average number of common shares outstanding during the period. For purposes of computing basic net income per share, the weighted-average number of outstanding shares of common stock excludes unvested restricted stock awards.

Diluted earnings per share is computed by dividing net income for the period by the weighted-average number of common shares outstanding during the period, plus the dilutive effect of unvested restricted stock awards, outstanding options and shares issuable under our employee stock purchase plans using the treasury stock method.

The following table provides a reconciliation of the numerators and denominators of the basic and diluted per share computations (in thousands, except per share amounts):

	Quarters Ended
	April 1,		April 2,
	2006		2005
Numerator:
Net income	$	24,717	$	30,471
Denominator:

Diluted weighted-average shares outstanding		132,264		141,099
Basic net income per share	$	0.19	$	0.22
Diluted net income per share	$	0.19	$	0.22

7

Weighted-average options to purchase approximately 20.2 million and 21.0 million shares of common stock at a weighted-average exercise price of $33.67 and $35.31 per share were outstanding for the quarters ended April 1, 2006 and April 2, 2005, respectively. These options were not included in the computation of diluted net income per common share because the effect would have been anti-dilutive. Restricted stock awards representing 0.2 million weighted-average shares were excluded from the computation of diluted shares outstanding as the shares were subject to performance conditions that had not been met as of April 1, 2006.

3. STOCK-BASED COMPENSATION

Adoption of SFAS 123(R)

The Company has adopted several stock plans that provide equity instruments to our employees and non-employee directors. Our plans include incentive and non-statutory stock options and restricted stock awards. Stock options generally vest ratably over a four-year period on the anniversary date of the grant, and expire ten years after the grant date. Restricted stock awards generally vest over a five-year period, excluding certain awards that vest upon the achievement of specific revenue performance targets. The Company also has employee stock purchase plans that allow qualified employees to purchase Company shares at 85% of the fair market value on specified dates.

Prior to January 1, 2006, we accounted for these stock-based employee compensation plans under the measurement and recognition provisions of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” or APB 25, and related Interpretations, as permitted by SFAS No. 123, “Accounting for Stock-Based Compensation,” or SFAS 123. With the exception of certain options assumed in acquisitions and grants of restricted stock awards, we generally recorded no stock-based compensation expense during periods prior to January 1, 2006 as all stock-based grants had exercise prices equal to the fair market value of our common stock on the date of grant. We also recorded no compensation expense in connection with our employee stock purchase plans as they qualified as non-compensatory plans following the guidance provided by APB 25. In accordance with SFAS 123 and SFAS 148, “Accounting for Stock-Based Compensation — Transition and Disclosure,” later in this Note 3 we disclose our net income and net income per share for the quarter ended April 2, 2005 as if we had applied the fair value-based method in measuring compensation expense for our stock-based compensation plans.

Effective January 1, 2006, we adopted the fair value recognition provisions of SFAS 123(R) using the modified prospective transition method. Under that transition method, compensation expense that we recognized for the quarter ended April 1, 2006 included: (a) compensation expense for all share-based payments granted prior to but not yet vested as of January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of SFAS 123, and (b) compensation expense for all share-based payments granted or modified on or after January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS 123(R). Compensation expense is recognized only for those awards that are expected to vest, whereas prior to the adoption of SFAS 123(R), we recognized forfeitures as they occurred. In addition, we elected the straight-line attribution method as our accounting policy for recognizing stock-based compensation expense for all awards that are granted on or after January 1, 2006. For awards subject to graded vesting that were granted prior to the adoption of SFAS 123(R), we use an accelerated expense attribution method. Results in prior periods have not been restated.

The following table summarizes the stock-based compensation expense for stock options, restricted stock awards and our employee stock purchase plans included in our results from continuing operations (in thousands):

	Quarter Ended
	April 1, 2006
Cost of sales	$	308
Selling, general and administrative		5,439
Research and development		3,061
Stock-based compensation expense before income taxes(1)		8,808
Income tax benefit		(3,391	)
Total stock-based compensation expense after income taxes	$	5,417

8

(1) Amount includes $1.7 million of stock-based compensation expense related to restricted stock awards.

During the quarter ended April 1, 2006, we capitalized stock-based compensation costs of $0.3 million, which were included as components of property and equipment, inventories and deferred profit.

The following table presents the impact of our adoption of SFAS 123(R) on the selected condensed consolidated statement of operations line items for the quarter ended April 1, 2006 (in thousands, except per share data):

Cash flows from financing activities		(68,054	)		3,820			(64,234	)

Prior to the adoption of SFAS 123(R), we presented deferred compensation as a separate component of shareholders’ equity. In accordance with the provisions of SFAS 123(R), on January 1, 2006, we reclassified the balance in deferred compensation to common stock on the balance sheet.

The adoption of SFAS 123(R) resulted in a benefit from a cumulative effect of a change in accounting principle of $0.9 million, net of tax. The benefit consists of a reduction of the cumulative expense recorded for restricted stock awards through December 31, 2005 in order to reflect estimated future forfeitures. Prior to the adoption of SFAS 123(R), we recorded forfeitures as they occurred as previously permitted under SFAS 123 and APB 25.

The following table illustrates the effect on our net income and net income per share for the quarter ended April 2, 2005 if we had applied the fair value recognition provisions of SFAS 123 to stock-based compensation using the Black-Scholes valuation model (in thousands, except per share data):

Valuation Assumptions For Stock Options

Valuation and Amortization Method. We estimate the fair value of stock options granted before and after the adoption of SFAS 123(R) using the Black-Scholes option valuation model. For options granted before January 1, 2006, we estimated the fair value using the multiple option approach and we are amortizing the fair value of options expected to vest on a graded vesting basis. For options granted on or after January 1, 2006, we estimate the fair value using a single option approach and amortize the fair value on a straight-line basis for options expected to vest. All options are amortized over the requisite service periods of the awards, which are generally the vesting periods.

Expected Term.The expected term of options granted represents the period of time that they are expected to be outstanding. We estimate the expected term of options granted based on our historical experience of grants, exercises and post-vesting cancellations in our option database. Contractual term expirations have not been significant.

Expected Volatility.We estimate the volatility of our stock options at the date of grant using a combination of historical and implied volatilities, consistent with SFAS 123(R) and SEC Staff Accounting Bulletin No. 107. Historical volatilities are calculated based on the historical prices of our common stock over a period at least equal to the expected term of our option grants, while implied volatilities are derived from publicly traded options of our common stock. Prior to the adoption of SFAS 123(R), we relied exclusively on the historical prices of our common stock in the calculation of expected volatility.

Risk-Free Interest Rate.The risk-free interest rate that we use in the Black-Scholes option valuation model is the implied yield in effect at the time of option grant based on U.S. Treasury zero-coupon issues with remaining terms equivalent to the expected term of our option grants.

Dividends.We have never paid any cash dividends on our common stock and we do not anticipate paying any cash dividends in the foreseeable future. Consequently, we use an expected dividend yield of zero in the Black-Scholes option valuation model.

Forfeitures.We use historical data to estimate pre-vesting option forfeitures. As required by SFAS 123(R), we record stock-based compensation expense only for those awards that are expected to vest. For the quarter ended April 1, 2006, our estimated annual forfeiture rate was 8.9%.

We used the following weighted-average valuation assumptions to estimate the fair value of options granted for the quarters ended April 1, 2006 and April 2, 2005:

	Quarters Ended
	April 1,			April 2,
	2006			2005
Risk-free interest rate		4.5	%		3.3	%
Expected volatility		48.6	%		70.0	%
Expected term	4.3 years			3.7 years
Expected dividends	None			None

10

The weighted-average fair value of options granted during the quarters ended April 1, 2006 and April 2, 2005 was $11.77 and $14.46, respectively.

Stock Options

A summary of stock option activity during the quarter ended April 1, 2006 is as follows (in thousands, except years and per-share amounts):

							Weighted-Average
	Number						Remaining
	of			Weighted-Average			Contractual		Aggregate
	Shares			Exercise Price			Term (in Years)		Intrinsic Value
Outstanding at January 1, 2006		24,137			$	31.79
Grants		79				26.65
Exercises		(260	)			19.07
Forfeitures or expirations		(525	)			32.44
Outstanding at April 1, 2006		23,431			$	31.90		6.4		$	11,655
Vested and expected to vest at April 1, 2006		22,617			$	31.01		6.3		$	11,553
Exercisable at April 1, 2006		17,942			$	33.56		5.7		$	10,995

The aggregate intrinsic value of options outstanding at April 1, 2006 is calculated as the difference between the exercise price of the underlying options and the market price of our common stock for the 1.6 million shares that had exercise prices that were lower than the market price of our common stock as of April 1, 2006. The total intrinsic value of options exercised during the quarter ended April 1, 2006 was $2.5 million, determined as of the date of exercise. The total cash received from employees as a result of stock option exercises during the quarter ended April 1, 2006 was $5.0 million. In connection with these exercises, the tax benefits realized by the Company for the quarter ended April 1, 2006 was $0.6 million. The Company settles employee stock option exercises with newly issued common shares.

As of April 1, 2006, there was $36.7 million of total unrecognized compensation cost related to unvested stock options which is expected to be recognized over a weighted-average period of 2.1 years.

In November 2005, we accelerated the vesting on approximately 3.8 million under-water options that were priced at $30.00 or above. By doing this, we reduced our future compensation expense by approximately $24.3 million on a pre-tax basis through 2008. Each of the Company’s executive officers at the time the acceleration became effective and whose options were accelerated entered into a Resale Restriction Agreement which imposes restrictions on the sale of any shares received through the exercise of accelerated options until the earlier of (i) the original vesting dates set forth in the option or (ii) the executive officer’s termination of employment.

Restricted Stock Awards

The following table summarizes our restricted stock award activity for the quarter ended April 1, 2006 (in thousands, except per share amounts):

11

	Number			Weighted-Average
	of			Grant Date
	Shares			Fair Value
Unvested restricted stock at January 1, 2006		1,197		$	27.57
Granted		5			27.67
Vested		(46	)		33.81
Forfeited		(24	)		29.34
Unvested restricted stock at April 1, 2006		1,132		$	27.30

As of April 1, 2006, there was $16.7 million of total unrecognized compensation cost related to restricted stock which is expected to be recognized over a weighted-average period of 3.0 years. The total fair value of restricted stock awards vested during the quarter ended April 1, 2006 was $1.2 million. As of April 1, 2006, there were a total of 0.2 million restricted shares subject to performance conditions that will result in forfeiture if the conditions are not realized.

ESPP

Under our employee stock purchase plans (ESPP), qualified employees are entitled to purchase shares at 85% of the fair market value on specified dates. ESPP awards were valued using the Black-Scholes model with expected volatility calculated using a six-month historical volatility. During the quarters ended April 1, 2006 and April 2, 2005, ESPP awards were valued using the following weighted-average assumptions:

	Quarters Ended
	April 1,			April 2,
	2006			2005
Risk-free interest rate		4.3	%		2.1	%
Expected volatility		31.5	%		40.0	%
Expected term	6 months			6 months
Expected dividends	None			None

The weighted-average fair value of ESPP shares during the quarters ended April 1, 2006 and April 2, 2005 was $5.30 and $6.96, respectively.

As of April 1, 2006, there was $0.2 million of total unrecognized compensation costs related to the ESPP that is expected to be fully recognized during the next fiscal quarter.

During each of the quarters ended April 1, 2006 and April 2, 2005, we reduced valuation allowances by approximately $1.2 million against certain net operating loss carryforwards recorded during the acquisition of SpeedFam-IPEC in 2002.

We completed the annual goodwill impairment test in the fourth quarter of 2005 in accordance with our policy. The first step of the test identifies when impairment may have occurred, while the second step of the test measures the amount of the impairment, if any. The results of our impairment tests did not indicate impairment. There have been no significant events or circumstances affecting the valuation of goodwill subsequent to our impairment test performed in the fourth quarter of 2005.

Intangible Assets

The following tables provide details of our acquired intangible assets (in thousands):

			Accumulated
April 1, 2006	Gross		Amortization			Net

Total	$	38,469	$	(13,649	)	$	24,820

Our estimated amortization expense for the identifiable intangible assets for each of the next five fiscal years will be approximately $6.1 million for 2007, $5.8 million for 2008, $3.2 million for 2009, $1.7 million for 2010 and $0.6 million for 2011. As of April 1, 2006, we have no identifiable intangible assets with indefinite lives.

7. ACQUISITION

In November 2005, we acquired 90% of the outstanding stock of Voumard Machine Co. SA, a privately-held manufacturer of high-precision machine manufacturing tools based in Neuchâtel, Switzerland. The acquisition of Voumard further enhances the product offerings in our Industrial Applications Group. We funded the purchase price of the acquisition with existing cash resources. Under the terms of the purchase agreement, we retained approximately $0.6 million. This amount will be released to the former shareholders of Voumard on the first anniversary of the purchase agreement, to the extent we have not made claims against the escrow for pre-acquisition contingencies.

The acquisition of Voumard was accounted for as a business combination in accordance with SFAS No. 141, “Business Combinations.” Tangible and intangible assets and liabilities were recorded at their estimated fair value. We will report changes related to the amounts described below in subsequent filings, as this information becomes available. We do not anticipate recording significant intangible assets as a result of this acquisition nor do we expect that the final purchase price allocation will differ significantly from this preliminary allocation.

The purchase price was allocated to the fair value of assets acquired and liabilities assumed as follows (in thousands):

Cash consideration	$	6,369
Estimated transaction costs		435
Total purchase price	$	6,804
Assets acquired	$	19,393
Liabilities assumed		(12,589	)
Total net assets acquired	$	6,804

8. PRODUCT WARRANTY

We record the estimated cost of warranty as a component of cost of sales upon system shipment. The estimated cost is determined by the warranty term as well as the average historical labor and material costs for a specific product. Should actual product failure rates or material usage differ from our estimate, revisions to the estimated warranty liability may be required. We review the actual product failure rates and material usage on a quarterly basis and adjust our warranty liability as necessary. Changes in our accrued warranty liability were as follows (in thousands):

	Quarters Ended
	April 1,			April 2,
	2006			2005
Balance, beginning of period	$	54,553		$	45,526
Warranties issued		20,400			21,630
Settlements		(21,113	)		(20,304	)
Changes in liability for pre-existing warranties, including expirations		1,982			1,127
Balance, end of period	$	55,822		$	47,979

9. RESTRUCTURING AND OTHER CHARGES

In an effort to consolidate operations, streamline our product offerings and align our manufacturing operations with current business conditions we have implemented several restructuring plans starting in 2001.

During the third quarter of 2005, we implemented a restructuring plan to relocate operations from Chandler, Arizona to San Jose, California and Tualatin, Oregon. In connection with this plan, we recorded restructuring charges of $6.0 million related to future lease payments, $1.3 million related to accelerated depreciation of leasehold improvements and $0.2 million related to other charges during the quarter ended April 1, 2006. The charges were partially offset by a $3.9 million benefit due to a change in estimate of sublease income related to facilities previously included in our restructuring accrual.

During the first quarter of 2006, we implemented a restructuring plan to dispose of certain owned facilities located in San Jose, California. As the anticipated period to close the sale of these assets is in excess of one year, the facilities did not qualify as held for sale at the end of the quarter. However, we did consider the change in planned use of the facilities as an indicator of impairment and determined that two of the properties were impaired. As a result, we recorded restructuring charges of $8.9 million to write these two facilities down to their estimated fair value during the quarter ended April 1, 2006. The other properties were not impacted as our analysis did not indicate an impairment.

All amounts are included in restructuring and other charges on our condensed consolidated statements of operations and are related to the Semiconductor Group.

The following table summarizes restructuring activity for the quarter ended April 1, 2006 (in thousands):

	Facility			Asset						Acquisition
	Exit Costs			Impairment			Severance			Expense			Total
Balance at December 31, 2005	$	27,239		$	—		$	863		$	198		$	28,300
Restructuring charges		6,235			10,199			51			—			16,485
Cash payments		(2,408	)		—			(484	)		(26	)		(2,918	)
Non-cash adjustment		1,161			(10,199	)		—			—			(9,038	)
Adjustment of prior restructuring costs		(3,856	)		—			—			—			(3,856	)
Balance at April 1, 2006	$	28,371		$	—		$	430		$	172		$	28,973

As of April 1, 2006, substantially all actions under our 2001 through 2005 restructuring plans had been completed, except for payments of future rent obligations. The remaining excess facility costs are stated at estimated fair value, net of estimated sublease income. We expect to pay remaining obligations in connection with vacated facilities no later than over the remaining lease terms, which expire on various dates through 2017.

10. LONG-TERM OBLIGATIONS

At April 1, 2006, we had borrowings of $127.0 million, denominated in Euros and Swiss Francs. These borrowings consisted of approximately $125.1 million, $0.7 million and $1.2 million with interest rates of 2.85%, 4.82% and 4.00%, respectively.

15

Substantially all of our borrowings are required to be secured by cash or marketable securities on deposit and are due and payable on or before June 30, 2009. Amounts to secure these borrowings are included within restricted cash on the condensed consolidated balance sheets.

11. COMPREHENSIVE INCOME

SFAS No. 130, “Reporting Comprehensive Income,” establishes standards for reporting and displaying comprehensive net income and its components in shareholders’ equity. Comprehensive income includes all changes in equity (net assets) during a period from non-owner sources. The change in accumulated other comprehensive income for all periods presented resulted from, net of tax foreign currency translation adjustments, unrealized gains and losses on investments, and unrealized changes in derivative instruments.

The following are the components of comprehensive income (in thousands):

	Quarters Ended
	April 1,		April 2,
	2006		2005
Net income	$	24,717	$	30,471
Other comprehensive income:
Foreign currency translation adjustments, net of tax		1,728		(2,744	)
Unrealized gain (loss) on available-for-sale securities, net of tax		1,163		(1,288	)
Unrealized change in derivative instruments, net of tax		41		—
Comprehensive income	$	27,649	$	26,439

The components of accumulated other comprehensive income (loss) are as follows (in thousands):

	April 1,			December 31,
	2006			2005
Foreign currency translation adjustments, net of tax	$	1,081		$	(647	)
Unrealized loss on marketable securities, net of tax		(727	)		(1,890	)
Unrealized change in derivative instruments, net of tax		41			—
Accumulated other comprehensive income (loss)	$	395		$	(2,537	)

12. PENSION PLAN

On June 28, 2004, we acquired Peter Wolters AG, including its existing pension plan. The pension balances at April 1, 2006 and December 31, 2005 were $7.0 million. The changes in the obligation during the quarter ended April 1, 2006 consisted of interest cost, service cost, benefit payments and currency translation adjustments, which were not significant.

13. RELATED PARTY TRANSACTIONS

We lease an aircraft from NVLS I, LLC, a third-party entity wholly owned by Richard S. Hill, our Chairman and Chief Executive Officer. Under the leasing agreement, we incurred rental expense of approximately $0.2 million and $0.1 million for the quarters ended April 1, 2006 and April 2, 2005, respectively.

Mr. Hill is a member of the Board of Directors of the University of Illinois Foundation. Novellus regularly provides research funding to certain groups, including the University of Illinois. Novellus provided research grants to the University of Illinois and certain of its professors in the amount of approximately $0.1 million for the quarter ended April 2, 2005. No grants were provided during the quarter ended April 1, 2006.

16

During the quarter ended April 2, 2005, Mr. Hill also served as a member of the Board of Directors of LTX Corporation. We recorded sublease income from LTX Corporation of approximately $0.4 million for the quarter ended April 2, 2005. In November 2005, Mr. Hill did not stand for reelection as a member of the Board of Directors of LTX Corporation.

During the quarters ended April 1, 2006 and April 2, 2005, Novellus employed, in non-executive positions, three immediate family members of our executive officers. The aggregate compensation amounts recognized for these immediate family members for each of the quarters ended April 1, 2006 and April 2, 2005 was approximately $0.1 million.

Historically, we have made secured and unsecured loans to our executive officers, vice presidents and other key personnel. Current regulations prohibit Company loans to “executive officers,” as defined by the Securities and Exchange Commission. We have no loans to our executive officers. However, we do have outstanding loans to non-executive vice presidents and other key personnel. As of April 1, 2006 and December 31, 2005, the total outstanding balance of loans to non-executive vice presidents and other key personnel was approximately $1.5 million. Of the total amount outstanding at April 1, 2006, $1.4 million was secured by collateral. Loans typically bear interest, except for those used for employee relocation purposes. We have not realized material bad debts related to the loans to our personnel.

14. LITIGATION

     Linear Technology Corporation

In March 2002, Linear Technology Corporation (Linear) filed a complaint against Novellus, among other parties, in the Superior Court of the State of California for the County of Santa Clara. The complaint seeks damages (including punitive damages) and injunctions for causes of actions involving alleged breach of contract, fraud, unfair competition, breach of warranty and declaratory relief. On September 3, 2004, Novellus filed a demurrer to all causes of action in the complaint, which the Court granted without leave to amend on October 5, 2004. On January 11, 2005, Linear filed a notice of appeal of the court’s order granting judgment in favor of Novellus. On June 15, 2005, Linear filed its opening appellate brief. Novellus filed a responsive brief on September 28, 2005. Linear filed its reply on November 18, 2005. The Court of Appeal has not yet set a date for oral argument. Although we prevailed on these claims in the Superior Court, it is possible that the Court of Appeal will reverse the ruling of the Superior Court, in which case Novellus could face potential liability on these claims. We cannot predict how the Court of Appeal will rule on this issue or, if it does rule against Novellus, estimate a range of potential loss, if any, due to the uncertainty of the appeals process.

     Other Litigation

In 2002, certain of Novellus’ present and former customers were sued for patent infringement by Plasma Physics Corporation (Plasma Physics) and Solar Physics Corporation (Solar Physics). Novellus believes that the named defendants in the Plasma Physics and Solar Physics litigation have settled or otherwise resolved their disputes with Plasma Physics and Solar Physics. Certain of these customers have previously informed Novellus or filed a complaint alleging that they believe Novellus may have indemnification obligations relating to this litigation. Although we have agreed and may in the future agree to a mutual resolution of a customer claim for indemnification, we believe that these matters will not have a material adverse impact on our business, financial condition, or overall trends in our results of operations. There can be no assurance, however, that we would prevail in any lawsuit filed in connection with the alleged indemnification obligations. If one or more customers were to prevail against us in such a suit and damages were awarded, the adverse impact on our business, financial condition, or results of operations could be material.

We are a defendant or plaintiff in various actions that arose in the normal course of business. We believe that the ultimate disposition of these other matters will not have a material adverse effect on our business, financial condition or results of operations. However, due to the uncertainty surrounding the litigation process, we are unable to estimate a range of loss, if any, at this time.

15. OPERATING SEGMENTS

SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information,” established standards for reporting information about operating segments in annual and interim financial statements. It also established standards for related disclosures about products and services, major customers and geographic areas. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker (CODM), in deciding how to allocate resources and in assessing performance. Our CODM is the Chief Executive Officer.

17

Our organizational structure is based on a number of factors that the CODM uses to evaluate, view and run our business operations which include, but are not limited to, customer base, homogeneity of products and technology. Our operating segments are based on this organizational structure and information reviewed by our CODM to evaluate the operating segment results. Our operations are organized into two segments: 1) Semiconductor Group; and 2) Industrial Applications Group. Our Semiconductor Group develops, manufactures, sells and supports equipment used in the fabrication of integrated circuits, commonly called microchips, or chips. Our Industrial Applications Group is a supplier of lapping, grinding, polishing and deburring products for fine-surface optimization.

Segment information for the periods presented is as follows (in thousands):

16. SUBSEQUENT EVENT

Subsequent to April 1, 2006, the Company reached an agreement to pay $3.3 million to settle a customer indemnity claim. The Company has included the effects of this settlement amount in its financial statements for the quarter ended April 1, 2006. The recording of this expense changes the Company’s April 19, 2006 announcement of preliminary first quarter financial results. Accordingly, net income and earnings per share for the quarter ended April 1, 2006 have been revised to reflect the impact of this agreement.

Introduction

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is intended to provide readers with an understanding of the Company. The following are included in our MD&A:

• Overview of our Business and Industry;

• Results of Operations;

• Critical Accounting Policies;

• Liquidity and Capital Resources; and

• Risk Factors.

Overview of Our Business and Industry

Novellus is a global supplier of semiconductor processing equipment used in the fabrication of integrated circuits. We develop, manufacture, sell and service equipment used by manufacturers of integrated circuits, or chips, who either incorporate the chips in their own products or sell the chips to other companies for use in electronic devices. We also are a supplier of lapping, grinding, polishing and deburring products for fine-surface optimization. Our goal is to use our expertise to increase our market share and strengthen our position in the markets we serve. To accomplish this, we endeavor to provide our customers with highly reliable products which help them compete effectively in their business by reducing their costs and increasing their productivity.

Our semiconductor processing equipment business primarily depends on capital expenditures made by chip manufacturers, who in turn are dependent on corporate and consumer demand for chips and the products which use them. The industry in which we operate is driven by spending for electronic products. As a consequence, our business is affected by growth or contraction in the global economy as well as by the adoption of new technologies. Demand for personal computers, the expansion of the Internet and telecommunications industries, and the emergence of new applications in consumer electronics have an impact on our business. In addition, the industry is characterized by intense competition and rapidly changing technology. We have worked closely with our customers and made substantial investments in research and development in order to continue delivering innovative products which enhance productivity for our customers and utilize the latest technology.

We focus on certain key quarterly financial data to manage our business. Net sales, gross profit, net income and net income per share are the primary measures we use to monitor performance. Net orders are used to forecast and plan future operations. Net orders consist of current period orders less current period cancellations. We report an order when a firm purchase order (or, in Japan, a letter of intent) is received and the agreed-upon delivery date is within twelve months (twenty-four months for the Industrial Applications Group).

The following table sets forth certain quarterly financial information for the periods indicated (in thousands, except per share information):

20

	Quarterly Financial Data
	2006		2005
	First		Fourth		Third		Second		First
	Quarter		Quarter		Quarter		Quarter		Quarter
Net sales	$	365,906	$	332,268	$	338,878	$	329,585	$	339,740
Gross profit	$	167,540	$	140,501	$	147,194	$	157,562	$	153,869
Net income	$	24,717	$	22,990	$	23,415	$	33,231	$	30,471
Diluted net income per share	$	0.19	$	0.17	$	0.17	$	0.24	$	0.22
Net orders	$	416,710	$	351,018	$	286,929	$	309,214	$	301,594

The semiconductor equipment industry is subject to cyclical conditions which play a major role in demand, as defined by net orders. Order fluctuations, in turn, affect our net sales. In 2005, demand for our products was volatile. In the first quarter of 2005, we experienced a sequential decrease in net orders of 9%, followed by a sequential increase of 3% in the second quarter, and a sequential decrease of 7% in the third quarter. In the fourth quarter of 2005, demand for our products began to increase and we experienced a sequential increase in net orders of 22%, followed by a sequential increase of 19% in the first quarter of 2006. During the first quarter of 2006, we continued to benefit from the net order growth that commenced in the fourth quarter of 2005, which was driven primarily by increases in the utilization of our customer’s production capacity. Due to the cyclical conditions in our industry, we expect that net orders will continue to vary sequentially.

The receipt of net orders in a particular quarter affects revenue in subsequent quarters. Net orders turn to revenue either at shipment or upon customer acceptance of the equipment. Our revenue recognition policy addresses the distinction between revenue recognized upon shipment and revenue recognized upon customer acceptance. Equipment generally ships within two or three months of receiving the related order. Customer acceptance, if applicable, is typically received three to six months after shipment. These time lines are general estimates and actual times may vary.

Results of Operations

Adoption of SFAS 123(R)

As discussed in Note 3, “Stock-Based Compensation,” in the notes to the condensed consolidated financial statements, we adopted the fair value recognition provisions of SFAS 123(R) using the modified prospective transition method effective January 1, 2006.

The following table summarizes the stock-based compensation expense for stock options, restricted stock and our ESPP (in thousands):

	Quarters Ended
	April 1, 2006		December 31, 2005		April 2, 2005
	(1)		(2)		(2)
Cost of sales	$	308	$	264	$	212
Selling, general and administrative		5,439		778		625
Research and development		3,061		468		376
Stock-based compensation expense before income taxes	$	8,808	$	1,510	$	1,213

(1)	Amounts include amortization expense related to stock options of $6.5 million, ESPP of $0.6 million and restricted stock awards of $1.7 million, recorded under SFAS 123(R).
(2)	Amounts include amortization expense related to restricted stock awards of $1.5 million and $1.2 million for the quarters ended December 31, 2005 and April 2, 2005, respectively, recorded under Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees.”

Net Sales

	Quarters Ended
	April 1, 2006			December 31, 2005			April 2, 2005
	(in thousands, except percentages)
Net sales	$	365,906		$	332,268		$	339,740
International net sales %		66	%		71	%		72	%

As compared to the prior year period, net sales during the three months ended April 1, 2006 increased by $26.2 million. This net increase is comprised of an increase of $40.9 million in the Semiconductor Group offset by a decrease of $14.7 million in the Industrial Applications Group. The increase in net sales in the Semiconductor Group is primarily attributable to higher volumes resulting from increased demand from our customers.

Geographical net sales as a percentage of total net sales were as follows (based upon the location of our customers’ facilities):

	Quarters Ended
	April 1, 2006			December 31, 2005			April 2, 2005
North America		34	%		29	%		28	%
Europe		7	%		12	%		9	%
Asia		59	%		59	%		63	%

A significant portion of our net sales is generated in Asia, primarily because a substantial portion of the world’s semiconductor manufacturing capacity is located there. We consider the Asia region to include Korea, Japan, Singapore, China and Taiwan. We plan to continue to focus on expanding our market presence in Asia, as we believe that significant additional growth potential exists in this region over the long term.

Gross Profit

	Quarters Ended
	April 1, 2006			December 31, 2005			April 2, 2005
	(in thousands, except percentages)
Gross profit	$	167,540		$	140,501		$	153,869
% of net sales		46	%		42	%		45	%

Our gross profit is affected by the treatment of certain product sales in accordance with SEC Staff Accounting Bulletin (SAB) No. 104, “Revenue Recognition.” For these sales, we recognize all of a product’s cost upon shipment even though a portion of a product’s revenue may be deferred until final payment is due, typically upon customer acceptance.

The gross profit percentage in quarter ended April 1, 2006 remained relatively flat from the quarter ended April 2, 2005. The adoption of SFAS 151, “Inventory Costs, an amendment of ARB No. 43, Chapter 4,” or SFAS 151, during the quarter ended April 1, 2006 positively impacted gross margin by approximately $2.6 million, due to increased absorption. The increase in gross profit percentage of approximately 4% in the quarter ended April 1, 2006 from the quarter ended December 31, 2005 is primarily attributed to the adoption of SFAS 151 and improvements in warranty costs and is partially offset by increased stock-based compensation expense due to the adoption of SFAS 123(R).

We are focused on improving our gross margins. This process involves working with our vendors to minimize costs, reviewing our current and future anticipated facility requirements to determine if facility reduction is necessary to achieve greater economies of scale, and continuing to outsource to take full advantage of available highly efficient manufacturing. The effort to make sustainable improvement in gross margins is an ongoing endeavor.

22

Selling, General and Administrative (SG&A)

	Quarters Ended
	April 1, 2006			December 31, 2005			April 2, 2005
	(in thousands, except percentages)
SG&A expense	$	58,482		$	51,489		$	51,760
% of net sales		16	%		15	%		15	%

SG&A expense includes compensation and benefits for corporate, financial, marketing, and administrative personnel as well as travel expenses and professional fees. Also included are expenses for rents, utilities, and depreciation and amortization related to the assets utilized by these functions. The increase in SG&A expense, in absolute dollars, for quarter ended April 1, 2006 from the prior year comparable period is primarily due to increased stock-based compensation expense, which reflects our adoption of SFAS 123(R), and increased compensation and benefits, which is attributable to increased salary costs.

Research and Development (R&D)

	Quarters Ended
	April 1, 2006			December 31, 2005			April 2, 2005
	(in thousands, except percentages)
R&D expense	$	63,783		$	60,492		$	62,048
% of net sales		17	%		18	%		18	%

R&D expense includes compensation and benefits for our research and development personnel, project materials, chemicals and other direct expenses incurred in product and technology development. Also included are expenses for equipment repairs and maintenance, rents, utilities and depreciation. The increase in R&D expense, in absolute dollars, for the quarter ended April 1, 2006 from the prior year comparable period is primarily due to increased stock-based compensation expense, which reflects our adoption of SFAS 123(R), and increased compensation and benefits, which is attributable to increased salary costs. Increases are partially offset by reduced spending on R&D initiatives.

Restructuring and Other Charges

	Quarters Ended
	April 1, 2006			December 31, 2005			April 2, 2005
	(in thousands, except percentages)
Restructuring and other charges	$	12,629		$	5,888		$	—
% of net sales		3	%		2	%		—	%

In an effort to consolidate operations, streamline our product offerings and align our manufacturing operations with current business conditions we have implemented several restructuring plans starting in 2001.

During the third quarter of 2005, we implemented a restructuring plan to relocate operations from Chandler, Arizona to San Jose, California and Tualatin, Oregon. In connection with this plan, we recorded restructuring charges of $6.0 million related to future lease payments, $1.3 million related to accelerated depreciation of leasehold improvements and $0.2 million related to other charges during the quarter ended April 1, 2006. The charges were partially offset by a $3.9 million benefit due to a change in estimate of sublease income related to facilities previously included in our restructuring accrual.

During the first quarter of 2006, we implemented a restructuring plan to dispose of certain owned facilities located in San Jose, California. As the anticipated period to close the sale of these assets is in excess of one year, the facilities did not qualify as held for sale at the end of the quarter. However, we did consider the change in planned use of the facilities as an indicator of impairment and determined that two of the properties were impaired. As a result, we recorded restructuring charges of $8.9 million to write these two facilities down to their estimated fair value during the quarter ended April 1, 2006. The other properties were not impacted as our analysis did not indicate an impairment.

23

All amounts are included in restructuring and other charges on our condensed consolidated statements of operations and are related to the Semiconductor Group. As a result of our restructuring plans implemented in the third quarter of 2005 and first quarter of 2006, we estimate that we will reduce our expenses by approximately $8.8 million in fiscal 2006. Actual savings may differ from our estimated savings.

Legal Settlement

	Quarters Ended
	April 1, 2006			December 31, 2005			April 2, 2005
	(in thousands, except percentages)
Legal settlement	$	3,250		$	—		$	—
% of net sales		1	%		—	%		—	%

For the quarter ended April 1, 2006, we recorded, as a subsequent event, a charge of $3.3 million to settle a customer indemnity claim.

We are a defendant or plaintiff in various actions that have arisen in the normal course of business. We believe that the ultimate disposition of these matters will not have a material adverse effect on our business, financial condition or overall trends in our results of operations.

Interest and Other Income, Net

	Quarters Ended
	April 1, 2006			December 31, 2005			April 2, 2005
	(in thousands, except percentages)
Interest and other income, net	$	6,079		$	13,368		$	3,469
% of net sales		2	%		4	%		1	%

Interest and other income, net, includes interest income, interest expense and other non-operating items. The increase in interest and other income, net, in absolute dollars for the quarter ended April 1, 2006 compared to the quarter ended April 2, 2005 consists primarily of increased interest income due to higher yields on interest-bearing securities.

Income Taxes

Our effective tax rates were 33.0% and 30% for the quarters ended April 1, 2006 and April 2, 2005, respectively. The effective tax rate for the quarter ended April 2, 2006 includes the tax benefits from our restructuring charges of approximately $12.6 million and legal settlement of approximately $3.3 million at the applicable statutory tax rate. Excluding the restructuring charges and legal settlement, our effective tax rate was 34.7% for the quarter ended April 1, 2006. The difference in the effective tax for the quarter ended April 1, 2006 compared to the quarter ended April 2, 2005 is primarily due to increased profits before taxes, further decreases in federal export incentives and the expiration of the federal research and development credit. Our future effective income tax rate depends on various factors, such as the Company’s profits (losses) before taxes, tax legislation, the geographic composition of pre-tax income, and non-deductible expenses incurred in connection with acquisitions.

Critical Accounting Policies

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, inventory valuation, goodwill and other intangible assets, deferred tax assets, warranty obligations, accounting for stock-based compensation, restructuring and impairment charges and foreign exchange contracts. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the current 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. We believe the following critical accounting policies affect the more significant judgments and estimates used in the preparation of our consolidated financial statements.

24

Revenue Recognition

We recognize revenue in accordance with SEC Staff Accounting Bulletin No. 104, “Revenue Recognition,” or SAB 104. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the seller’s price is fixed or determinable, and collectibility is reasonably assured.

Certain of our equipment sales are accounted for as multiple-element arrangements. A multiple-element arrangement is a transaction which may involve the delivery or performance of multiple products, services, or rights to use assets, and performance may occur at different points in time or over different periods of time. Our equipment sales generally have two elements: delivery of the equipment and installation of the equipment/customer acceptance. If we have met defined customer acceptance experience levels with both the customer and the specific type of equipment, we recognize revenue for the equipment element upon shipment and transfer of title, with the installation and acceptance element recognized at customer acceptance. All costs associated with equipment sales accounted for as multiple-element arrangements are recognized upon shipment and transfer of title. All revenue and associated costs for all other equipment sales are recognized upon customer acceptance.

Installation services are not essential to the functionality of the delivered equipment. In accordance with EITF 00-21, “Revenue Arrangements with Multiple Deliverables,” we allocate revenue based on the residual method as a fair value has been established for installation services. However, since final payment is not typically billable until customer acceptance, we defer revenue for the final payment until customer acceptance.

Revenue related to sales of spare parts is recognized upon shipment. Revenue related to maintenance and service contracts is recognized ratably over the duration of the contracts. Unearned maintenance and service contract revenue is included in other accrued liabilities.

Inventory Valuation

We periodically assess the recoverability of all inventories, including raw materials, work-in-process, finished goods, and spare parts, to determine whether adjustments for impairment are required. Inventory that is obsolete or in excess of our forecasted usage is written down to its estimated realizable value based on assumptions about future demand and market conditions. If actual demand is lower than our forecast, additional inventory write-downs may be required.

Goodwill and Other Intangible Assets

We review our long-lived assets, including goodwill and other intangible assets, for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. In accordance with our policy, we completed the goodwill impairment test in the fourth quarter of 2005. The first step of the test identifies when impairment may have occurred, while the second step of the test measures the amount of the impairment, if any. The results of our impairment tests did not indicate impairment.

Deferred Tax Assets

We record a valuation allowance to reduce our deferred tax assets to the amount that is more likely than not to be realized. As of April 1, 2006, we had approximately $111.0 million of deferred tax assets, net of a valuation allowance of $62.5 million principally related to acquired net operating loss carryforwards and foreign tax credits that are not realizable until 2009 and beyond. The valuation allowance includes $39.7 million related to acquired deferred tax assets of SpeedFam-IPEC, which will be credited to goodwill when realized and $18.4 million related to stock option deductions, which will be credited to equity when realized. Management believes that the majority of deferred tax assets will be realized due to anticipated future income. We have considered future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance. If in the future we determine that we would not be able to realize all or part of our net deferred tax assets, an increase to the valuation allowance for deferred tax assets would decrease income in the period in which such determination is made.

Warranty Obligations

Our warranty policy generally states that we will provide warranty coverage for a predetermined amount of time on systems and modules for material and labor to repair and service the equipment. We record the estimated cost of warranty coverage to cost of sales upon system shipment. The estimated cost of warranty is determined by the warranty term, as well as the average historical labor and

25

material costs for a specific product. Should actual product failure rates or material usage differ from our estimates, revisions to the estimated warranty liability may be required. These revisions could have a positive or negative impact on gross profit. We have experienced a decline in our gross margins, partly as a result of changes in our liability for pre-existing warranties. These adverse changes to our liability may continue, causing negative affects on our future operating results. We review the actual product failure rates and material usage rates on a quarterly basis and adjust our warranty liability as necessary.

Accounting for Stock-Based Compensation

Prior to January 1, 2006, we accounted for stock-based employee compensation plans under the measurement and recognition provisions of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” or APB 25, and related Interpretations, as permitted by SFAS No. 123, “Accounting for Stock-Based Compensation,” or SFAS 123. With the exception of certain options assumed in acquisitions and grants of restricted stock awards, we generally recorded no stock-based compensation expenses during periods prior to January 1, 2006 as all stock-based grants had exercise prices equal to the fair market value of our common stock on the date of grant. We also recorded no compensation expense in connection with our employee stock purchase plans as they qualified as non-compensatory plans following the guidance provided by APB 25. In accordance with SFAS 123 and SFAS 148, “Accounting for Stock-Based Compensation — Transition and Disclosure,” we disclosed our net income or loss and net income or loss per share as if we had applied the fair value based method in measuring compensation expense for our stock-based compensation programs. Under SFAS 123, we elected to calculate our compensation expense by applying the Black-Scholes valuation model, applying the graded vesting expense attribution method and recognizing forfeited awards in the period that they occurred.

Effective January 1, 2006, we adopted the fair value recognition provisions of SFAS 123(R) using the modified prospective transition method. Under that transition method, compensation expense that we recognized for the quarter ended April 1, 2006 included: (a) compensation expense for all share-based payments granted prior to but not yet vested as of January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of SFAS 123, and (b) compensation expense for all share-based payments granted or modified on or after January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS 123(R). Compensation expense is recognized only for those awards that are expected to vest, whereas prior to the adoption of SFAS 123(R), we recognized forfeitures as they occurred. In addition, we elected the straight-line attribution method as our accounting policy for recognizing stock-based compensation expense for all awards that are granted on or after January 1, 2006. For awards subject to graded vesting that were granted prior to the adoption of SFAS 123(R), we use an accelerated expense attribution method. Results in prior periods have not been restated.

We estimate the fair value of options granted using the Black-Scholes option valuation model and the assumptions shown in Note 3, “Stock-Based Compensation,” to the condensed consolidated financial statements. We estimate the expected term of options granted based on the history of grants, exercises and post-vesting cancellations in our option database. Contractual term expirations have not been significant. We estimate the volatility of our common stock at the date of grant based on a combination of historical and implied volatilities, consistent with SFAS 123(R) and SEC Staff Accounting Bulletin No. 107. Prior to the adoption of SFAS 123(R), we relied exclusively on the historical prices of our common stock in the calculation of expected volatility. We base the risk-free interest rate that we use in the Black-Scholes option valuation model on the implied yield in effect at the time of option grant on U.S. Treasury zero-coupon issues with remaining terms equivalent to the expected term of our option grants. We have never paid any cash dividends on our common stock and we do not anticipate paying any cash dividends in the foreseeable future. Consequently, we use an expected dividend yield of zero in the Black-Scholes option valuation model. We use historical data to estimate pre-vesting option forfeitures and record stock-based compensation expense only for those awards that are expected to vest. For options granted before January 1, 2006, we estimated the fair value using the multiple option approach and we are amortizing the fair value on a graded vesting basis. For options granted on or after January 1, 2006, we estimate the fair value using a single option approach and amortize the fair value on a straight-line basis. All options are amortized over the requisite service periods of the awards, which are generally the vesting periods. We may elect to use different assumptions under the Black-Scholes option valuation model in the future if our current experience indicates that a different measure is preferable, which could materially affect our net income or loss and net income or loss per share.

Restructuring and Impairment Charges

Restructuring activities initiated prior to December 31, 2002 were recorded in accordance with Emerging Issues Task Force Issue No. 94-3, “Liability Recognition for Certain Employee Termination Benefits and Other Costs to Exit an Activity (Including Certain Costs Incurred in a Restructuring),” and restructuring activities after December 31, 2002 were recorded under the provisions of SFAS

26

No. 146, “Accounting for Costs Associated with Exit or Disposal Activities,” or SFAS No. 146; SFAS No. 112, “Employers’ Accounting for Postemployment Benefits”; and SAB 100, “Restructuring and Impairment Charges,” or SAB 100. SFAS No. 146 requires that a liability for costs associated with an exit or disposal activity be recognized when the liability is incurred, rather than when the exit or disposal plan is approved.

We account for business combination restructurings under the provisions of EITF Issue No. 95-3, “Recognition of Liabilities in Connection with a Purchase Business Combination” and SAB 100. Accordingly, restructuring accruals are recorded when management initiates an exit plan that will cause the Company to incur costs that have no future economic benefit. Certain restructuring charges related to long-lived asset impairments are recorded in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets.”

The restructuring accrual related to vacated facilities is calculated net of estimated sublease income. Sublease income is estimated based on current market quotes for similar properties and expected occupancy dates. If we are unable to sublet these vacated properties as forecasted, if we are forced to sublet them at rates below our current estimates due to changes in market conditions, or if we change our sublease income estimate, we will adjust the restructuring accruals accordingly.

Foreign Exchange Contracts

We enter into forward foreign exchange contracts to buy and sell foreign currencies to hedge the parent’s intercompany balances denominated in a currency other than the U.S. dollar. The maturities of these instruments are generally less than 12 months. In 2006 and 2005, these hedging contracts were denominated primarily in the Taiwanese Dollar, Singapore Dollar, the Euro and the Japanese Yen. The effect of exchange rate changes on forward exchange contracts is expected to offset the effect of exchange rate changes on the underlying hedged items. We believe these financial instruments do not subject us to speculative risk that would otherwise result from changes in currency exchange rates. The gain (loss) recognized in other income, net related to these transactions was $0.9 million and ($1.2) million during the quarters ended April 1, 2006 and April 2, 2005, respectively.

We also enter into forward exchange contracts to buy and sell foreign currencies to hedge certain forecasted intercompany transactions, which represent foreign currency risk. These intercompany transactions consist of forecasted charges to our international subsidiaries for purchases of inventories, which are subsequently resold to third party customers. The intercompany charges are denominated in U.S. dollars, while the third party sales are denominated primarily in Japanese Yen. We expect the hedge of these forecasted transactions to be highly effective in offsetting potential changes to cash flows attributed to fluctuating exchange rates. For these derivatives, the gain or loss from the effective portion of the hedge is reported as a component of accumulated other comprehensive income (loss) and is reclassified into earnings in the period in which the hedged transaction affects earnings, and within the same income statement line item as the impact of the hedged transaction. Any gain or loss from the ineffective portion of the hedge in excess of the cumulative change in the present value of future cash flows of the hedged item and any amounts excluded from the assessment of hedge effectiveness are recognized as a component of cost of sales during the period of change. As of April 1, 2006, the gains, net of losses, recorded to accumulated other comprehensive income (loss) were less than $0.1 million. For the quarter ended April 1, 2006 we recorded gains, net of losses, of $0.6 million for the ineffective portion of these hedges within cost of sales.

Liquidity and Capital Resources

We have historically financed our operating and capital resource requirements through cash flows from operations, sales of equity securities and borrowings. Our primary source of cash at April 1, 2006 consisted of $612.0 million of cash, cash equivalents and short-term investments. This amount represents a decrease of $37.2 million from $649.2 million at December 31, 2005. The decrease was due primarily to repurchases of common stock of $68.1 million, offset by net cash provided by operating activities of $30.6 million and net sales and maturities of short term investments of $46.5 million.

Net cash provided by operating activities during the quarter ended April 1, 2006 was $30.6 million. This amount consisted primarily of $24.7 million provided by net income, adjusted for non-cash items of approximately $40.3 million. The net changes in working capital accounts used was approximately $34.4 million.

Net cash provided by investing activities for the three months ended April 1, 2006 was $36.5 million, which consisted primarily of net sales and maturities of short-term investments of $46.5 million, offset primarily by capital expenditures of $9.1 million. As of April 1, 2006, we had no significant commitments to purchase property or equipment.

27

Net cash used in financing activities for the quarter ended April 1, 2006 was $64.2 million. This amount consisted primarily of repurchases of common stock of $68.1 million and net payments on lines of credit $4.5 million, offset by proceeds from employee stock compensation plans of $4.6 million and an excess tax benefit of $3.8 million.

Effective June 25, 2004, two of our European subsidiaries entered into a credit arrangement that allowed for borrowings of up to $153.1 million. On June 28, 2004, we borrowed the entire amount available to fund the acquisition of Peter Wolters AG and for general corporate purposes. Borrowings are secured by cash or marketable securities on deposit and included within restricted cash on the consolidated balance sheet. As of April 1, 2006, $125.8 million of the loan was outstanding. All borrowings under the credit arrangement are due and payable on or before June 28, 2009.

In November 2005, we acquired 90% of the outstanding stock of Voumard Machine Co. SA, based in Neuchâtel, Switzerland. Voumard has a credit arrangement that allows borrowings up to $1.2 million. As of April 1, 2006, the entire amount was outstanding and is payable on or before December 31, 2037.

Our subsidiaries in Asia and Europe have lines of credit with various banks with total borrowing capacity of $50.4 million. The lines of credit bear interest at various rates, expire on various dates through March 2007 and can be used for general operating purposes. Borrowings of $11.2 million were outstanding under these credit facilities as of April 1, 2006.

We believe that our current cash position, cash generated through operations and equity offerings, and available borrowing capacity will be sufficient to meet our needs at least through the next twelve months.

ITEM 4: CONTROLS AND PROCEDURES

Quarterly Evaluation of Our Disclosure Controls and Internal Controls

As of the end of the period covered by this Quarterly Report on Form 10-Q, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures and our internal controls and procedures for financial reporting. This controls evaluation was done under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer. Rules adopted by the Securities and Exchange Commission, or the SEC, require that in this section of the Quarterly Report on Form 10-Q, we present the conclusions of the CEO and the CFO about the effectiveness of our disclosure controls and internal controls for financial reporting based on and as of the date of the controls evaluation.

CEO and CFO Certifications

The certifications of the Chief Executive Officer and the Chief Financial Officer required in accordance with Section 302 of the Sarbanes-Oxley Act of 2002 are filed as exhibits to this Quarterly Report on Form 10-Q. This section of the Quarterly Report on Form 10-Q is the information concerning the controls evaluation referred to in the Section 302 certifications and this information should be read in conjunction with the Section 302 certifications for a more complete understanding of the topics presented.

Disclosure Controls and Internal Controls for Financial Reporting

Disclosure controls are procedures that are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934, or the Exchange Act, such as this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls are also designed with the objective of ensuring that such information is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

28

Internal controls for financial reporting are procedures which are designed with the objective of providing reasonable assurance that our transactions are properly authorized, our assets are safeguarded against unauthorized or improper use and our transactions are properly recorded and reported, all to permit the preparation of our financial statements in conformity with U.S. generally accepted accounting principles.

Limitations on the Effectiveness of Controls

The Company’s management, including the Chief Executive Officer and the Chief Financial Officer, does not expect that our disclosure controls or our internal controls for financial reporting will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Scope of the Controls Evaluation

The evaluation of our disclosure controls and our internal controls for financial reporting by our Chief Executive Officer and our Chief Financial Officer included a review of the objective and design of the controls, our implementation of the controls and the effect of the controls on the information generated for use in this Quarterly Report on Form 10-Q. In accordance with SEC requirements, the Chief Executive Officer and the Chief Financial Officer note that, during our most recent fiscal quarter, there have been no changes in our internal controls for financial reporting that have materially affected or are reasonably likely to materially affect our internal controls for financial reporting.

Conclusions

Based upon the controls evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, subject to the limitations noted above, our disclosure controls are effective to ensure that material information relating to the Company is made known to management, including the Chief Executive Officer and the Chief Financial Officer, particularly during the period when our periodic reports are being prepared, and that our internal controls for financial reporting are effective to provide reasonable assurance that our financial statements are fairly presented in conformity with U.S. generally accepted accounting principles.

PART II: OTHER INFORMATION

ITEM 1: LEGAL PROCEEDINGS

There were no material developments in our litigation matters that occurred during the quarter ended April 1, 2006. Subsequent to April 1, 2006, we reached an agreement to settle a customer indemnity claim. The cost of this settlement has been included in the results of operations for the quarter ended April 1, 2006. For more detailed information on litigation matters outstanding please see Item 3 “Legal Proceedings,” in our Annual Report on Form 10-K for the year ended December 31, 2005.

We are a defendant or plaintiff in various actions that have arisen in the normal course of business. We believe that the ultimate disposition of these matters will not have a material adverse effect on our business, financial condition or overall trends in our results of operations.

ITEM 1A: RISK FACTORS

Set forth below and elsewhere in this Quarterly Report on Form 10-Q and in other documents we file with the SEC, are risks and uncertainties that could cause actual results to differ materially from the results expressed or implied by the forward-looking statements contained in this Quarterly Report.

29

The following risk factors, “We face risks related to intellectual property,” “We are exposed to risks related to our indemnification of third parties,” and “We face risks related to changes in accounting standards for stock option plans” have been updated from the prior version of these risk factors as set forth in our Annual Report on Form 10-K for the year ended December 31, 2005, filed with the SEC on March 16, 2006.

Cyclical downturns in the semiconductor industry negatively impact demand for our equipment.

Our business depends predominantly on the capital expenditures of semiconductor manufacturers, which in turn depend on current and anticipated market demand for integrated circuits and the products that use them. The semiconductor industry has historically been cyclical and has experienced periodic downturns that have had a material adverse effect on the demand for semiconductor processing equipment, including equipment that we manufacture and market. The rate of changes in demand is accelerating, rendering the global semiconductor industry increasingly volatile. During periods of reduced and declining demand, we must be able to quickly and effectively align our costs with prevailing market conditions, as well as motivate and retain key employees and maintain a stable management team. Our inventory levels during periods of reduced demand have at times been higher than optimal. We cannot provide any assurance that we will not be required to make inventory valuation adjustments in future periods. During periods of rapid growth, we must be able to acquire and/or develop sufficient manufacturing capacity to meet customer demand, and hire and assimilate a sufficient number of qualified people. In each of the years 2001 through 2006, we have implemented restructuring plans to align our business with fluctuating conditions. Future restructuring plans may be required to respond to future changes. Net orders and net sales may be adversely affected if we fail to respond to changing industry cycles in a timely and effective manner. We experienced a downturn in demand in the first quarter of 2005, with a slight increase in the second quarter of 2005, a decrease in the third quarter of 2005 and increases in the fourth quarter of 2005 and first quarter of 2006. We cannot provide any assurance that this increase will be sustainable, and our net sales and operating results may be adversely affected if demand does not continue to grow and if downturns or slowdowns in the rate of capital investment in the semiconductor industry occur in the future.

The competitive and capital-intensive nature of the semiconductor industry increases the difficulty of maintaining and capturing market share.

We face substantial competition in the industry, from both potential new market entrants and established competitors. Competitors may have greater financial, marketing, technical or other resources, and greater ability to respond to pricing pressures, than we do. They may also have broader product lines, greater customer service capabilities, or larger and more established sales organizations and customer bases. To maintain or capture a position in the market, we must develop new and enhanced systems and introduce them at competitive prices on a timely basis, while managing our research and development and warranty costs. Semiconductor equipment manufacturers incur substantial costs to install and integrate capital equipment into their production lines. This increases the likelihood of continuing relationships with chosen equipment vendors, including our competitors, and the difficulty of penetrating new customer accounts. In addition, sales of our systems depend in significant part upon a prospective customer’s decision to increase or expand manufacturing capacity — which typically involves a significant capital commitment. From time to time, we have experienced delays in finalizing system sales following initial system qualification. Due to these and other factors, our systems typically have a lengthy sales cycle, during which we may expend substantial funds and management effort. Heightened competition may also force price reductions that could adversely affect our results of operations.

Rapid technological change in the semiconductor industry requires substantial research and development expenditures and responsiveness to customer needs.

We devote a significant portion of our personnel and financial resources to research and development programs, and we seek to maintain close relationships with our customers in order to remain responsive to their product and manufacturing process needs. Our success depends in part on our ability to accurately predict evolving industry standards, to develop innovative solutions and improve existing technologies, to win market acceptance of our new and advanced technologies and to manufacture our products in a timely and cost-effective manner. Our products and processes must address changing customer needs in a range of materials, including copper and aluminum, at ever-smaller line widths and feature sizes, while maintaining our focus on manufacturing efficiency and product reliability. If we do not continue to gain market acceptance for our new technologies and products, or develop and introduce improvements in a timely manner in response to changing market conditions or customer requirements, or remain focused on research and development efforts that will translate into greater revenues, our business could be seriously harmed.

In the semiconductor capital equipment market, technological innovations tend to have long development cycles. We have experienced delays and technical and manufacturing difficulties from time to time in the introduction of certain of our products and product enhancements. In addition, we may experience delays and technical and manufacturing difficulties in future introductions or volume production of our new systems or enhancements. The increased costs and reduced efficiencies that may be associated with the

30

development, manufacture, sale and support of future products or product enhancements relative to our existing products, may adversely affect our operating results.

Our success in developing, introducing and selling new and enhanced systems depends upon a variety of factors, including product selection; hiring, retaining and motivating highly qualified design and engineering personnel; timely and efficient completion of product design and development; implementation of manufacturing and assembly processes; achieving specified product performance in the field; and effective sales and marketing. There can be no assurance that we will be successful in selecting, developing, manufacturing and marketing new products, or in enhancing our existing products. There can be no assurance that revenue from future products or product enhancements will be sufficient to recover our investments in research and development. To ensure the functionality and reliability of our future product introductions or product improvements, we incur substantial research and development costs early in development cycles, before we can confirm the technical feasibility or commercial viability of a product or product improvement. If new products have reliability or quality problems, reduced orders, or higher manufacturing costs, delays in collecting accounts receivable and additional service may result and warranty expenses may rise, affecting our gross margins. Any of these events could materially and adversely affect our business, financial condition or results of operations.

We are exposed to the risks of global operations.

We serve an increasingly global market. Substantial operations outside of the United States and export sales expose us to certain risks that may adversely affect our operating results and net sales, including, but not limited to:

• Tariffs and other trade barriers;

• Challenges in staffing and managing foreign operations and providing prompt and effective field support to our customers outside of the United States;

• Difficulties in managing foreign distributors;

• Potentially adverse tax consequences, including withholding tax rules that may limit the repatriation of our earnings, and higher effective income tax rates in foreign countries where we conduct business;

• Governmental controls, either by the United States or other countries, that restrict our business overseas or the import or export of semiconductor products, or increase the cost of our operations;

• Longer payment cycles and difficulties in collecting accounts receivables outside of the United States;

• Inadequate protection or enforcement of our intellectual property and other legal rights in foreign jurisdictions;

• Global or regional economic downturns;

• Geo-political instability, natural disasters, acts of war or terrorism; and

• Fluctuations in interest and foreign currency exchange rates, creating the need to enter into forward foreign exchange contracts to hedge against the short-term impact of currency fluctuations, specifically transactions denominated in Japanese yen. Exchange rate volatility may also increase the cost of our exported products for international customers and inhibit demand.

There can be no assurance that any of these factors will not have a material adverse effect on our business, financial condition or results of operations. In addition, each region in the global semiconductor equipment market exhibits unique market characteristics that can cause capital equipment investment patterns to vary significantly from period to period. We derive a substantial portion of our revenues from customers in Asia. Any negative economic developments or geo-political instability in Asia, including the possible outbreak of hostilities or epidemics involving China, Taiwan, Korea or Japan, could result in the cancellation or delay by certain significant customers of orders for our products, which could adversely affect our business, financial condition or results of operations. Our continuing expansion in Asia renders us increasingly vulnerable to these risks.

Our quarterly operating results and stock price are unpredictable.

We have experienced and expect to continue to experience significant fluctuations in our quarterly operating results, which may adversely affect our stock price. Our future quarterly operating results and stock price may not align with past trends. The factors that could lead to fluctuations in our results include, but are not limited to:

• Building our systems according to forecast, instead of limited backlog information, which hinders our ability to plan production and inventory levels;

• Variability in manufacturing yields;

• Failure to receive anticipated orders in time to permit shipment during the quarter;

31

• Timing and cancellation of customer orders and shipments, including deferring orders of our existing products due to new product announcements by us and/or our competitors;

• Changing demand for and sales of lower-margin products relative to higher-margin products;

• Competitive pricing pressures;

• The effect of revenue recognized upon acceptance with little or no associated costs; and

• Fluctuation in warranty costs.

Changes in tax rates or liabilities could negatively impact our future results.

We are subject to taxation in the U.S. and other foreign countries. Our future tax rates could be affected by changes in the composition of earnings in countries with differing tax rates, changes in the valuation of deferred tax assets and liabilities, or changes in the tax laws. We are also subject to regular examination of our tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of favorable or unfavorable outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. Although we believe that our tax estimates are reasonable, there can be no assurance that any final determination will not be materially different from the treatment reflected in our historical income tax provisions and accruals. Factors that could cause estimates to be materially different include, but are not limited to:

• Changes in the regulatory environment;

• Changes in accounting and tax standards or practices; and

• Overall business conditions in the semiconductor equipment industry.

We face risks associated with acquisitions.

We have made — and may in the future make — acquisitions of or significant investments in businesses with complementary products, services and/or technologies. Acquisitions involve numerous risks, including, but not limited to:

• Difficulties in integrating the operations, technologies, products and personnel of acquired companies;

• Lack of synergies or the inability to realize expected synergies and cost-savings;

• Revenue and expense levels of acquired entities differing from those anticipated at the time of the acquisitions;

• Difficulties in managing geographically dispersed operations;

• The potential loss of key employees, customers and strategic partners of acquired companies;

• Claims by terminated employees, shareholders of acquired companies or other third parties related to the transaction;

• The issuance of dilutive securities, assumption or incurrence of additional debt obligations or expenses, or use of substantial portions of our cash;

• Diversion of management’s attention from normal daily operations of the business; and

• The impairment of acquired intangible assets as a result of technological advancements, or worse-than-expected performance of acquired companies.

Acquisitions are inherently risky, and we cannot provide any assurance that our previous or future acquisitions will be successful. The inability to effectively manage the risks associated with previous or future acquisitions could materially and adversely affect our business, financial condition or results of operations.

We are exposed to risks associated with our diversification strategy.

Our core business and expertise has historically been in the development, manufacture, sale and support of deposition technologies, and more recently, wafer surface preparation and chemical mechanical planarization technologies. Our acquisitions of Peter Wolters and Voumard and the establishment of our Industrial Applications Group represent the first expansion of our business beyond the semiconductor equipment industry. We lack experience in the high-precision machine manufacturing equipment market, compared with our knowledge of the semiconductor equipment industry, and cannot give any assurance that we can maintain or improve the quality of products, level of sales, or relations with significant employees, customers or suppliers, that are necessary to compete in the market for high-precision machine manufacturing tools. Our efforts to integrate and develop the Industrial Applications Group may divert capital, management attention, research and development and other critical resources away from, and adversely affect our core business.

32

We face risks related to concentration of net sales.

We currently sell a significant proportion of our systems in any particular period to a limited number of customers, and we expect that sales of our products to a relatively few customers will continue to account for a high percentage of our net sales in the foreseeable future. Although the composition of the group comprising our largest customers varies from year to year, the loss of a significant customer or any reduction in orders from any significant customer — including reductions due to customer departures from recent buying patterns, as well as economic or competitive conditions in the semiconductor industry — could materially and adversely affect our business, financial condition or results of operations.

We face risks related to intellectual property.

We intend to continue to seek legal protection, primarily through patents and trade secrets, for our proprietary technology. Seeking patent protection is a lengthy and costly process, and there can be no assurance that patents will be issued from any pending applications, or that any claims allowed from existing or pending patents will be sufficiently broad to protect our proprietary technology. There is also no guarantee that any patents we hold will not be challenged, invalidated or circumvented, or that the rights granted thereunder will provide competitive advantages to us, given the speed with which technology becomes obsolete in the semiconductor industry. Our competitors have developed and may continue to develop and obtain patents to technologies that are similar or superior to our technologies. In addition, the laws of foreign jurisdictions in which we develop, manufacture or sell our products may not protect our intellectual property rights to the same extent as do the laws of the United States.

Adverse outcomes in current or future legal disputes regarding patent and intellectual property rights could result in the loss of our proprietary rights, subject us to significant liabilities to third parties, require us to seek licenses from third parties on terms that may not be reasonable or favorable to us, prevent us from manufacturing or selling our products, or compel us to redesign our products to avoid incorporating third parties’ intellectual property. As a result, our product offerings may be delayed, and we may be unable to timely meet customers’ requirements. Regardless of the merit of any legal disputes, we incur substantial costs to prosecute or defend our intellectual property rights. Even if our products do not infringe third parties’ intellectual property rights, we have in the past and may in the future elect to seek licenses or enter into settlements to avoid the costs of protracted litigation and diversion of resources and management attention. However, if the terms of settlements entered into with certain of our competitors are not observed or enforced, we may suffer further costs. Any of these circumstances could have a material adverse effect on our business, financial condition or results of operations during any reported fiscal period.

Our ability to develop intellectual property depends on hiring, retaining and motivating highly qualified design and engineering staff with the knowledge and technical competence to advance our technology and productivity goals. To protect our trade secrets and proprietary information generally, we have entered into confidentiality or invention assignment agreements with our employees, as well as consultants and other parties. If these agreements are breached, our remedies may not be sufficient to cover our losses.

We are exposed to risks related to our indemnification of third parties.

From time to time, in the normal course of business, we indemnify third parties with whom we enter into contractual relationships, including customers, lessors, and parties to other transactions with us, with respect to certain matters. We have agreed, under certain conditions, to hold these third parties harmless against specified losses, such as those arising from a breach of representations or covenants, other third party claims that our products when used for their intended purposes infringe the intellectual property rights of such other third parties or other claims made against certain parties. We have been, and in the future may be, compelled to enter into or accrue for probable settlements of alleged indemnification obligations or subject to potential liability arising from our customer’s involvements in legal disputes. It is difficult to determine the maximum potential amount of liability under any indemnification obligations, whether or not asserted, due to our limited history of prior indemnification claims and the unique facts and circumstances that are likely to be involved in each particular claim. Our business, financial condition and results of operations in a reported fiscal period could be materially adversely affected if we expend significant amounts in defending or settling any purported claims, regardless of their merit or outcomes.

The loss of key employees could harm our business and operations.

Our employees are extremely important to our success and our key management, engineering and other employees are difficult to replace. The expansion of high technology companies has increased demand and competition for qualified personnel. If we are unable to retain key personnel, or if we are not able to attract, assimilate or retain additional highly qualified employees to meet our needs in the future, our business and operations could be harmed.

33

Supply shortages could affect our ability to meet customer demands.

Our growth and ability to meet customer demands depend in part of on our ability to obtain timely deliveries of parts, components and sub-assemblies for the manufacture and support of our products from our suppliers. Although we make reasonable efforts to ensure that such parts are available from multiple suppliers, certain key parts may only be obtained from a single source or from limited sources. These suppliers are in some cases thinly capitalized, independent companies who derive a significant amount of their business from us and/or a small group of other companies in the semiconductor industry. Our supply channels may be vulnerable to disruption. Any such disruption to or termination of our supplier relationships may result in a prolonged inability to secure adequate supplies at reasonable prices or of acceptable quality, and may adversely effect our ability to bring new products to market and deliver them to customers in a timely manner. As a result, our revenues and operations may be harmed.

We are exposed to risks associated with outsourcing activities.

We also outsource the manufacture of major subassemblies, which enables us to focus on performing system design, assembly and testing in-house, thereby minimizing our fixed costs and capital expenditures. Although we make reasonable efforts to ensure that third party providers will perform to our standards, our reliance on suppliers and subcontractors limits our control over quality assurance and delivery schedules. Defects in workmanship, unacceptable yields, manufacturing disruptions and difficulties in obtaining export and import approvals may impair our ability to manage inventory and cause delays in shipments and cancellation of orders that may adversely affect our relationships with current and prospective customers and enable competitors to penetrate our customer accounts. In addition, third party providers may prioritize capacity for larger competitors or increase prices to us, which will affect our ability to respond to pricing pressures from competitors and customers, and our profitability.

If our outside audit firm does not maintain its “independence,” we may be unable to meet our regulatory reporting obligations.

Our independent registered public accounting firm communicates with us at least annually regarding any relationships between the firm and Novellus that, in the firm’s professional judgment, might have a bearing on the firm’s independence with respect to Novellus.

If our independent registered public accounting firm finds that it cannot confirm that it is independent of Novellus based on existing securities laws and registered public accounting firm independence standards, we could experience delays or otherwise fail to meet our regulatory reporting obligations.

Corporate governance and financial reporting compliance requirements may lead to increased costs and difficulty in attracting qualified executive officers and directors.

To comply with the requirements of the Sarbanes-Oxley Act of 2002, as well as new rules subsequently implemented by the SEC and adopted by NASDAQ in response to Sarbanes-Oxley, we have made changes to our financial reporting, securities disclosure and corporate governance practices. In 2005, we incurred increased legal and financial compliance costs due to these new and evolving rules, regulations, and listing requirements, and management time and resources were re-directed to ensure current and implement future compliance initiatives. These rules may make it more difficult for us to attract and retain qualified executive officers and members of our Board of Directors, particularly to serve on our audit committee, as well as make it more costly to obtain liability insurance coverage for our officers and directors.

We face risks related to changes in accounting standards for stock option plans.

Beginning in the first fiscal quarter of 2006, we adopted SFAS 123(R), which requires us to recognize compensation expense in our statement of operations for the fair value of stock options granted to our employees over the related vesting periods of the stock options. The requirement to expense stock options granted to employees reduces their attractiveness as a compensation vehicle because the expense associated with these grants results in compensation charges. In addition, the expenses recorded may not accurately reflect the value of our stock options because the option pricing models commonly used under SFAS 123(R) were not developed for use in valuing employee stock options and are based on highly subjective assumptions, including the option’s expected life and the price volatility of the underlying stock. Alternative compensation arrangements that can replace stock option programs may also negatively impact profitability. Stock options remain an important employee recruitment and retention tool, and we may not be able to attract and retain key personnel if we reduce the scope of our employee stock option programs. Our employees are critical to our ability to develop and design systems that advance our productivity and technology goals, increase our sales goals and provide support to customers. Accordingly, as a result of the requirements of SFAS 123(R), our profitability can be expected to be reduced compared to periods prior to adoption of the new standard.

34

We are exposed to risks associated with our investment activities.

Our ability to compete in the semiconductor manufacturing industry depends on our success in developing new and enhanced technologies that advance the productivity and innovation advantages of our products. To further these goals, we have formed the Novellus Development Company, a venture fund that enables us to invest in emerging technologies and strengthen our technology portfolio for both existing and potentially new market opportunities. Although the fund intends to make enquiries reasonably necessary to make an informed decision as to the companies and technologies in which it will invest, we cannot provide any assurance as to any future return on investment or ability to bring new technologies to market. There are risks inherent in investing in start-up companies, which may lack a stable management team, operating history or adequate cash flow. The securities in which the fund may invest may not be registered under the Securities Act or any applicable state securities laws, and may be subject to restrictions on marketability or transferability. Given the nature of the investments that may be contemplated by the fund, there is a significant risk that it will be unable to realize its investment objectives by sale or other disposition, or will otherwise be unable to identify or develop any commercially viable technology. In particular, these risks could arise from changes in the financial condition or prospects, management inexperience and lack of research and development resources of the companies in which investments are made, and evolving technological standards. Investments contemplated by the fund may divert management time and attention, as well as capital, away from our core operating business. Any future losses on investments attributable to the fund may materially and adversely impact our business, financial condition and operating results.
