RACKABLE SYSTEMS, INC. AND SUBSIDIARIES

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. BUSINESS

Rackable Systems, Inc. (“Rackable Systems” or the “Company”) was incorporated in the state of Delaware in December 2002 in connection with the acquisition of substantially all the assets and liabilities of Rackable Systems’ predecessor company referred to herein as Old Rackable. It has subsidiaries in Canada, Hong Kong and Ireland. The Company recently moved its headquarters from Milpitas, California to Fremont, California. The principal business of Rackable Systems is the design, manufacture and implementation of highly scalable compute servers and high-capacity storage systems, which are sold to customers such as large internet businesses, and companies in vertical markets such as semiconductor design, enterprise software, federal government, entertainment, financial services, oil and gas, biotechnology and pharmaceuticals.

2. BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements included herein have been prepared by the Company in accordance with the published rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) applicable to interim financial information. Certain information and footnote disclosures included in financial statements prepared in accordance with the generally accepted accounting principles in the United States of America have been omitted in these interim statements as allowed by such SEC rules and regulations. However, management believes that the disclosures herein are adequate to make the information presented not misleading. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements of the Company for the fiscal year ended December 30, 2006, which are included in the Company’s Annual Report on Form 10-K.

In the opinion of management, the accompanying condensed consolidated financial statements contain all normal and recurring adjustments necessary for a fair statement of financial position, results of operations and cash flows for the periods indicated.

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities (including inventory valuation, accounts receivable valuation, accrued warranty, reserves for uncertain tax positions and estimated fair values of stock options) and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates.

The Company uses a 52 week calendar fiscal year, with each fiscal quarter consisting of 13 weeks. The latest fiscal year ended on December 30, 2006. The second quarter of fiscal 2006 ended on July 1, 2006 and the second quarter of fiscal 2007 ended on June 30, 2007.

The Company’s critical accounting policies, significant judgments and estimates are discussed in its Annual Report on Form 10K for its fiscal year ended December 30, 2006. Except for the adoption of the provisions of Financial Accounting Standards Board (“FASB”) Interpretation No. 48,Accounting for Uncertainty in Income Taxes(“FIN 48”), on January 1, 2007, there have been no significant changes. (See Note 6.)

Recent Accounting Pronouncements

In September 2006, the FASB issued Statement of Financial Accounting Standards No. 157 (“SFAS 157”),Fair Value Measurements,which defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurements. SFAS 157 does not require any new fair value measurements, but provides guidance on how to measure fair value by providing a fair value hierarchy used to classify the source of the information. SFAS 157 is effective beginning July 1, 2008. The Company is evaluating the potential impact of the adoption of SFAS 157 on the Company’s financial position, cash flows or results of operations.

In February 2007, the FASB issued SFAS 159, The Fair Value Option for Financial Assets and Financial Liabilities – Including an Amendment of FASB Statement No. 115,which is effective for fiscal years beginning after November 15, 2007. This statement permits an entity to choose to measure many financial instruments and certain other items at fair value at specified election dates. Subsequent unrealized gains and losses on items for which the fair value option has been elected will be reported in earnings. The Company is currently evaluating the potential impact of this statement.

6

In March 2007, the FASB issued EITF Abstract 07-3,Accounting for Nonrefundable Advance Payments for Goods and Services to Be Used in Future Research and Development Activities, which is effective for fiscal years beginning after December 15, 2007. This abstract requires that non refundable advance payments for future research and development activities should be deferred and capitalized. Such amounts should be recognized as an expense as the goods are delivered or the related services are performed. The Company is currently evaluating the potential impact of this statement.

3. EARNINGS PER SHARE

In accordance with SFAS No. 128,Earnings Per Share, basic net income (loss) per common share has been computed by using the weighted average number of shares of common stock outstanding during the period, less the shares subject to repurchase. The following table reconciles the number of shares used in the basic and diluted net income (loss) per share computation for the periods presented (in thousands, except per share amounts):

	Three Months Ended					Six Months Ended
	June 30, 2007			July 1, 2006		June 30, 2007			July 1, 2006
Numerators:
Net income (loss)	$	(40,448	)	$	5,326	$	(50,605	)	$	11,298
Denominators:
Weighted-average common shares outstanding		28,801			27,693		28,622			25,984
Unvested weighted-average common shares subject to repurchase		(237	)		—		(229	)		—
Weighted-average shares— Basic		28,564			27,693		28,393			25,984
Dilutive effect of employee stock options		—			1,557		—			1,767
Dilutive effect of employee stock purchase plan		—			—		—			—
Dilutive effect of unvested restricted stock		—			—		—			—
Weighted-average shares— Diluted		28,564			29,250		28,393			27,751
Net income (loss) per common share—Basic	$	(1.42	)	$	0.19	$	(1.78	)	$	0.43
Net income (loss) per common share—Diluted	$	(1.42	)	$	0.18	$	(1.78	)	$	0.41

Common equivalent shares issuable upon exercise of all options, employee stock purchase plan and unvested restricted stock have not been included in the calculation of diluted loss per share because they would have been anti-dilutive for the three and six months ended June 30, 2007.

4. SHORT TERM INVESTMENTS

Short term investments consist of investments in marketable debt securities, primarily U.S. Agency Notes, Municipal Bonds and Commercial Papers. At June 30, 2007 and December 30, 2006, all of Rackable Systems’ marketable debt securities were classified as available-for-sale and were carried at fair market value. The unrealized gains (losses) on available-for-sale securities are recorded in accumulated other comprehensive loss.

In the six months ended June 30, 2007 and July 1, 2006, amortization of intangible assets was $1,871,000 and $760,000, respectively. Amortization is computed using the straight-line method over the estimated useful life of the intangible asset.

Accrued Expenses

Accrued expenses consist of the following (in thousands):

	June 30, 2007		December 30, 2006
Accrued sales and use tax	$	9,323	$	11,367

Total accrued expenses	$	21,832	$	19,894

In December 2005, the Company identified potential state sales and use tax liabilities relating to previous years product sales to customers outside of California. At December 30, 2006, the Company estimated the gross tax liability to the states was $7.2 million which is shown above in accrued sales and use tax. Also included in accrued sales and use tax as of December 30, 2006 is $4.2 million related to current sales and use tax payable. The Company also quantified the exposure relating to interest and estimated collection exposures and, accordingly, recorded a $0.7 million charge to general and administrative expense in the fiscal year ended December 30, 2006. For the six months ended June 30, 2007, the $7.2 million estimated gross tax liability was decreased by payments of $6.5 million, and increased by $0.7 million related to net accruals, to $1.4 million which was recorded in accrued sales and use tax. The increase in the estimated gross tax liability was a result of additional information received during the quarter relating to customers and their self assessment process. Accrued sales and use tax of $9.3 million includes current sales and use tax payable of $6.9 million in addition to the $1.4 million liability discussed above and accruals of $0.7 million and $0.3 million of sales and use tax related to a California and Washington sales and use tax, respectively. The Company received an initial estimated assessment in the six month ended June 30, 2007 related to its California Sales Tax audit. The Company also recorded a $1.9 million charge to general and administrative expense in the first half of 2007 related to additional accruals related to the prior year sales and use tax liabilities, California sales and tax audit and a reserve for Washington sales tax. The Company believes that it will recover certain sales tax from its customers, and accordingly has recorded a receivable for $5.0 million which is included in other current assets as of June 30, 2007.

As part of the Company’s assessment of excess and obsolete inventory, a loss accrual of $2,651,000 was recorded for purchase order commitments on hand and ordered at June 30, 2007.

6. INCOME TAXES

The income tax provision for the three and six months ended June 30, 2007 was $11.4 million and $5.5 million, respectively. The income tax provision for the three months ended June 30, 2007 includes a $13.2 million charge for an increase in the valuation allowance for deferred tax assets. During the three months ended June 30, 2007, the Company revised its assessment of the realizability of its deferred tax assets due to significant year-to-date and anticipated losses before income tax provision for the twelve months ended December 29, 2007. As a result, management of the Company in applying the provisions of SFAS No. 109, concluded that it was more likely than not that deferred tax assets in excess of amounts recoverable through loss carry-back would not be realizable. The $13.2 million discrete charge for the increase in valuation allowance was partially offset by a $215,000 tax benefit resulting from a reversal of a liability previously recorded for an uncertain tax position and related accrued interest as a result of a tax audit settled in the three months ended June 30, 2007.

The tax provision for the three and six months ended July 1, 2006 was $3.9 million and $8.2 million, respectively. The effective income tax rate of 42.4% and 42.0% for the three and six months ended July 1, 2006 approximated the combined federal and net state statutory income tax rate.

During the six months ended July 1, 2006, the Company recorded $12.4 million of excess tax benefits related to stock option exercises as a financing cash inflows and a change to prepaids and other assets of $4.3 million associated with the benefit from excess tax deductions as an operating cash outflow.

The Company adopted the provisions of FASB Interpretation No. 48,Accounting for Uncertainty in Income Taxes (“FIN 48”), on January 1, 2007. As a result of adoption, the Company recorded an increase to retained earnings of approximately $386,000. As of the date of adoption and after the impact of recognizing the decrease in the liability noted above, the Company’s unrecognized tax benefits totaled approximately $192,000 and would affect the Company’s effective tax rate if recognized. The Company recognizes accrued interest related to unrecognized tax benefits and penalties, if incurred, as components of income tax expense. Accrued interest as of date of adoption of FIN 48 was $101,000 ($61,000 net of related tax benefit). The unrecognized tax benefits and related accrued interest (net of related tax benefit) were recorded in the balance sheet as of the date of adoption as “Other Long-Term Liabilities.”

During the three months ended June 30, 2007, the Internal Revenue Service completed its examination of the Company’s 2004 tax federal income tax return with no changes to the return. The Company recorded a $215,000 income tax benefit related to previously recorded uncertain tax positions and accrued interest. The Company’s Canadian subsidiary was also recently notified that it will be subject to audit by the Quebec tax authorities for the 2003 to 2005 pre-acquisition tax years. There are no unrecognized tax benefits associated with Canadian federal or provincial income taxes.

7. ACQUISITION

In September 2006, the Company completed its acquisition of Terrascale Technologies, Inc. (“Terrascale”). The purchase price was $39.4 million, which included $1.5 million related to a loan made to Terrascale prior to closing. The acquisition was accounted for using the purchase method of accounting in accordance with SFAS No. 141,Business Combinations (“SFAS 141”), and accordingly the Company’s consolidated financial statements from September 8, 2006 include the impact of the acquisition. The purchase price included $7.8 million of contingent consideration which vests based upon continued employment and will be paid out to continuing employees over the third through eighth quarters following the closing of the acquisition. Terrascale stock options were exchanged in the acquisition and became options to purchase 30,419 shares of Rackable Systems common stock at an exercise price of $5.86 per share which have a fair value of $647,000.

The total adjusted purchase price of $33.3 million (the total purchase price of $39.4 million plus $2.0 million of acquisition related expenses less $7.8 million of contingent consideration and approximately $317,000 related to the fair value of unvested and unearned stock options, discussed above) was allocated to the tangible and intangible assets acquired and liabilities assumed based upon their respective estimated fair values at the acquisition date with the excess purchase price allocated to goodwill. The valuation of the identifiable intangible assets acquired was prepared based on management’s estimates and assumptions. The following table summarizes the allocation of the total adjusted purchase price, as of the date of the acquisition (in thousands):

11

Current assets	$	2,417
Property and equipment		195
In-process research and development		2,840
Amortizable intangible assets:
Existing technology		8,256
Customer relationships		633
Contract backlog and maintenance contracts		263
Non-competition agreements		319
Goodwill		20,051
Total assets acquired		34,974
Current liabilities		1,170
Long-term liabilities		514
Total liabilities assumed		1,684
Net assets acquired	$	33,290

Development projects that had not reached technological feasibility, and had no future alternative uses were classified as in-process research and development (“IPRD”). The $2.8 million value allocated to projects that were identified as IPRD were charged to expense in the third quarter of 2006. The Company’s IPRD relates to developing a new version of the current software platform. The value assigned to IPRD was primarily determined utilizing the income approach which presumes that the value of an asset can be estimated by the net economic benefit (i.e. cash flows) to be received over the life of the asset, discounted to present value utilizing a discount rate of 21%. The estimated cost to complete the IPRD projects was approximately $900,000. All projects are expected to be completed during 2007.

The following unaudited pro forma consolidated financial data represents the combined results of operations as if Terrascale’s business had been combined with the Company at the beginning of the six months ended July 1, 2006. This pro forma financial data includes the straight line amortization of intangibles over their respective estimated useful lives (in thousands, except per share amounts):

	Six Months Ended July 1, 2006
Revenue	$	173,332
Operating income	$	13,936
Net income	$	9,806
Basic income per share	$	0.38
Diluted income per share	$	0.35

The unaudited pro forma results of operations are presented for illustrative purposes only. They are not intended to represent what the Company’s results of operations would have been if the acquisition had occurred at that date or to project the Company’s results of operations for any future period.

On April 4, 2007, the Company and the former shareholders of Terrascale executed an agreement for the Company’s purchase of all of the rights of the Distributed Parity Engine (“DPE”), a patent application and intellectual property rights related to a technology previously licensed to the Company. Originally, the Company had an option to retain the rights to DPE technology for a payment of $9.0 million to the former shareholders. The option expired on March 6, 2007. The Company and the former shareholders subsequently agreed to transfer the rights to the DPE technology to the Company for $9.1 million.

8. STOCK-BASED COMPENSATION

Determining Fair Value

The fair value of stock-based awards was estimated using the Black-Scholes model with the following weighted-average assumptions for the three and six months ended June 30, 2007 and July 1, 2006:

	Three Months Ended						Six Months Ended
	June 30, 2007			July 1, 2006			June 30, 2007			July 1, 2006
Option Plan Shares
Expected term (in years)		5.4			5.8			5.4			5.6
Volatility		58	%		59	%		60	%		56	%
Expected dividend		—			—			—			—
Risk-free interest rate		4.7	%		5.0	%		4.7	%		4.8	%
Estimated annual forfeitures		10.5	%		8.3	%		10.5	%		8.3	%
Weighted-average fair value	$	7.13		$	26.32		$	9.78		$	22.07
ESPP Shares
Expected term (in years)		1.25			0.5 – 1.0			1.25			0.5 – 1.0
Volatility		54	%		49	%		54	%		49	%
Expected dividend		—			—			—			—
Risk-free interest rate		5.0	%		4.7	%		5.0	%		4.7	%
Weighted-average fair value	$	7.00		$	14.25		$	7.00		$	14.25

The computation of expected life for the three and six months ended June 30, 2007 is based on an analysis of the relevant industry sector post-vest termination rates and the exercise factors. The expected volatility is based on a combination of the implied and historical volatility for both the Company and its peer group. The interest rate is based on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term. Where the expected term of the Company’s stock-based awards do not correspond with the terms for which interest rates are quoted, the Company performed a straight-line interpolation to determine the rate from the available term maturities. The estimated forfeiture rate was based on an analysis of the relevant industry sector pre-vest termination rate, as the Company believes that its historical forfeiture rates are not representative of future expectations, given that a substantial portion of the Company’s stock options were granted subsequent to its initial public offering in June 2005.

Stock Compensation Expense

Stock Compensation Expense— The following table shows total stock-based compensation expense included in the condensed consolidated statement of operations (in thousands):

	Three Months Ended				Six Months Ended
	June 30, 2007		July 1, 2006		June 30, 2007		July 1, 2006
Cost of revenue	$	743	$	819	$	1,412	$	1,525
Research and development		961		973		2,897		1,484
Selling and marketing		1,621		1,369		3,635		2,223
General and administrative		2,993		978		6,262		1,664
Total	$	6,318	$	4,139	$	14,206	$	6,896

As required by SFAS 123R, management made an estimate of expected forfeitures and is recognizing compensation costs only for those equity awards expected to vest.

At June 30, 2007, there was $40.6 million of total unrecognized compensation cost related to nonvested stock options and awards. That cost is expected to be recognized over a weighted average period of 1.61 years.

On June 11, 2007, the Company filed a tender offer on Form SC TO-I (“Tender Offer”) with the SEC under which holders of options with exercise prices greater than $16.00 per share could tender their options in exchange for restricted stock units granted under the 2005 Equity Incentive Plan based upon the following exchange ratios:

Exercise Price Range	Stock Option Shares per Restricted Stock Unit
$16.00-24.99	2 to 1
$25.00-$34.99	3 to 1
$35.00 and above	3.5 to 1

14

The restricted stock units will be subject to vesting in equal quarterly installments through August 15, 2009 (if the grant date of the option being tendered was prior to October 1, 2006) or August 15, 2010 (if the grant date of the option being tendered was after October 1, 2006). The tender offer provided that the optionholder could and must submit their election to participate in the tender offer no later than July 10, 2007, and could amend their election up to that date. Furthermore, the Company could at its sole discretion amend, extend or withdraw the tender offer at anytime prior to closing. The tender offer closed on July 10, 2007. (See Note 12)

At June 30, 2007, the total compensation cost related to options to purchase the Company’s common stock under the 2005 ESPP but not yet recognized was approximately $665,000. This cost will be amortized on a straight-line basis over periods of up to two years.

Balance—end of period	$	1,386		$	826		$	1,386		$	826

Lease Commitment—The Company has leases for its office, manufacturing and warehousing facilities. The total future minimum lease payments amount to $10.2 million over the lease term.

Line of Credit—The Company has line of credit agreement with a bank that provides for borrowings not to exceed $25.0 million and expires on September 29, 2007. The line of credit agreement contains: financial covenants that specify minimum quarterly profitability of at least $1 in any two consecutive quarters, excluding FAS 123R expense and acquisition related charges; a minimum unencumbered U.S. liquidity; and tangible net worth requirements. Borrowings under the line of credit bear interest, at the option of the Company, at prime or adjusted LIBOR plus 185 basis points. There were no borrowings under the line of credit at June 30, 2007. At June 30, 2007, the Company was not in compliance with the minimum quarterly profitability covenant. On July 31, 2007, the bank waived the minimum quarterly profitability covenant as of June 30, 2007.

Indemnification Agreements—The Company enters into standard indemnification agreements with its customers and certain other business partners in the ordinary course of business. These agreements include provisions for indemnifying the customer against any claim brought by a third party to the extent any such claim alleges that the Company’s product infringes a patent, copyright or trademark, or misappropriates a trade secret, of that third party. The agreements generally limit the scope of the available remedies in a variety of industry-standard methods, including but not limited to product usage and geography-based limitations, a right to control the defense or settlement of any claim, and a right to replace or modify the infringing products to make them non-infringing. The Company has not incurred significant expenses related to these indemnification agreements and no material claims for such indemnifications are outstanding as of June 30, 2007. As a result, the Company believes the estimated fair value of these indemnification agreements, if any, to be de minimus; accordingly, no liability has been recorded with respect to such indemnifications as of June 30, 2007.

16

General—From time to time, the Company is party to certain other claims and legal proceedings that arise in the course of business. There are no such matters at June 30, 2007 which, in the opinion of management, will have a material adverse effect on the Company’s financial position or results of operations.

Company Overview

We develop, market and sell server and storage systems purpose-built for large-scale data center deployments. Recently, enterprises have begun to deploy large-scale computing and storage farms by aggregating large numbers of relatively inexpensive, open-standard modular computing and storage systems. These systems typically run low-cost operating systems such as Linux and Windows and, we believe, enable enterprises to meet their computing and storage requirements at a lower total cost of ownership and provide enterprises with greater flexibility and scalability.

We have developed innovative technologies in the areas of chassis and cabinet design, power distribution techniques and hardware-based remote management technology. Our compute servers use our half-depth design, enabling back-to-back mounting for higher server density and improved thermal management. We also offer full depth compute servers to our customers. Sales of our compute servers in the six months ended June 30, 2007 and July 1, 2006 accounted for 89% and 91% of our total revenue, respectively. We also offer low-cost, high-capacity storage systems, which leverage many of our core server technologies, to help enterprises cost-effectively meet their increasing data storage requirements. Our storage servers represented approximately 11% and 9% of our total revenue for the six months ended June 30, 2007 and July 1, 2006, respectively. We market our systems primarily through our direct sales force predominantly to enterprises within the United States. In the six months ended June 30, 2007 and July 1, 2006, international sales were 4% and 12% of our sales, respectively. Our international sales were unusually high as a percent of our total sales in the six months ended July 1, 2006 because of a significant sale in Europe to one of our top three customers. We are still in the early stages of developing an international sales and operational presence, focusing initially on Europe and China. We focus our sales and marketing activities on enterprises that typically purchase hundreds of servers and tens or hundreds of terabytes of storage per year. To date, we have sold our products to over 300 customers. We have concentrated our marketing efforts on leading internet companies, as well as customers with high-performance computing requirements in vertical markets such as semiconductor design, enterprise software, federal government, media, financial services, oil and gas exploration, biotechnology and pharmaceuticals.

In June 2005, we completed our initial public offering. Aggregate net proceeds from the offering, after deducting underwriting discounts and commissions and issuance costs, were approximately $67.4 million. We used $27.7 million of the offering proceeds to redeem all of our outstanding shares of preferred stock and to repay the promissory notes and accrued interest of approximately $3.0 million previously issued to our founders. In addition, we used $14.1 million of the offering proceeds to repay our line of credit. In December 2005, we completed a follow-on public offering, and aggregate net proceeds to us from that offering, after deducting underwriting discounts and commissions, and issuance costs, were approximately $46.2 million. In March 2006, we completed a second follow-on public offering. Aggregate net proceeds from the offering, after deducting underwriting discounts and commissions and issuance costs, were approximately $138.5 million.

Terrascale Acquisition

On September 8, 2006, we completed our acquisition of Terrascale. Terrascale is a provider of a clustered file system solution enabling high performance input/output connectivity between servers and commodity-based storage subsystems. The total purchase consideration was $39.4 million including $7.8 million which will be accounted for as compensation expense. In April 2007, we also acquired all of the rights to certain technology for a payment of $9.1 million to the former shareholders of Terrascale.

18

Fiscal Periods

We use a 52 week calendar fiscal year, with each quarter consisting of 13 weeks. The second quarter of our 2006 fiscal year ended on July 1, 2006. The second quarter of our 2007 fiscal year ended on June 30, 2007. The last quarter of our 2006 fiscal year ended on December 30, 2006.

Critical Accounting Policies, Significant Judgments and Estimates

Our critical accounting policies, significant judgments and estimates are discussed in our Annual Report on Form 10K for our fiscal year ended December 30, 2006. Except for the adoption of the provisions of Financial Accounting Standards Board (FASB) Interpretation No. 48,Accounting for Uncertainty in Income Taxes(“FIN 48”), on January 1, 2007, there have been no significant changes. See Note 6 of the condensed consolidated financial statements.

Results of Operations

The following table sets forth our financial results, as a percentage of revenue, for the three and six months ended June 30, 2007 and July 1, 2006.

Comparison of the three and six months ended June 30, 2007 and July 1, 2006

Revenue.

	Three months ended				Change					Six months ended				Change
	June 30, 2007		July 1, 2006		$			%		June 30, 2007		July 1, 2006		$			%
	(in thousands, except percentages)									(in thousands, except percentages)

The decline in revenue for the three months ended June 30, 2007 was due to the following factors:

• Lower sales to customers that historically have represented greater than 10% of revenues. In the three months ended June 30, 2007, revenue from these customers was approximately 62% of revenue as compared to 67% of revenue in the three months ended July 1, 2006.

• Increased competitive pressure, particularly in our top three accounts, resulted in the average selling price per unit decreasing by 15% in the three months ended June 30, 2007 as compared to average selling price per unit in the three months ended July 1, 2006.

The decline in revenue for the six months ended June 30, 2007 was due to the following factors:

• Lower sales to customers that historically have represented greater than 10% of revenues. In the six months ended June 30, 2007, revenue from these customers was approximately 62% of revenue as compared 74% of revenue, in the six months ended July 1, 2006.

• Increased competitive pressure, particularly in our top three accounts, resulted in the average selling price per unit decreasing by 9% in the six months ended June 30, 2007 as compared to average selling price per unit in the six months ended July 1, 2006.

Based on expected purchasing patterns and the competitive environment, we expect the percent of revenue from our top three customers to be lower in the second half of 2007 as compared to the second half of 2006. We do however, expect sequential growth in revenue from our non-top three customers in the second half of 2007 as compared to the second half of 2006.

In the three months ended June 30, 2007 we had a gross loss of $6.9 million as compared to a gross profit of $20.2 million in the three months ended July 1, 2006. In the three months ended June 30, 2007 we recorded a $20.6 million expense, or 25% of revenue, related to the write down of excess and obsolete inventory as compared to $210,000, or less than 1% of revenue, in the three months ended July 1, 2006. The significant write down for excess and obsolete inventory recorded in the three months ended June 30, 2007 was due to the following:

• A significant reduction in our forecasted usage for the next twelve months as compared to estimates prevailing at the time of purchase of the inventory, due in part to the overall reduction of revenue estimates for 2007;

20

• A customer driven, technology platform shift from AMD to Intel, affecting demand for memory (particularly DDR1 1G), motherboards, CPUs and chassis that we had previously purchased;

• In the fourth quarter of fiscal 2006, we issued purchase orders for power supplies based on a forecasted usage for the following three quarters because of lead times that can extend beyond six months. However, lower than expected revenue from 2007 and a shift in customer preference to next generation power supplies created an excess in power supplies on hand; and

Other factors that impacted gross profit (loss) in the three months ended June 30, 2007 as compared to the three months ended July 1, 2006 were:

• significantly lower margins from revenue from our top three customers as a result of aggressive pricing from our competitors;

• less absorption of manufacturing overhead expense due to lower production activity during the quarter; and

• increased overhead expense due to a headcount increase of 62 partially offset by a decrease in stock based compensation expense.

In the six months ended June 30, 2007, we had a gross profit of $2.1 million as compared to a gross profit of $39.7 million in the six months ended July 1, 2006. In the six months ended June 30, 2007, we recorded a $20.8 million expense (which includes the $20.6 million recorded in the three month period ended June 30, 2007), or 14% of revenue, related to the write down of excess and obsolete inventory, discussed above, as compared to $532,000, or less than 1% of revenue, in the six months ended July 1, 2006.

Other factors that impacted gross margin in the six months ended June 30, 2007 as compared to the six months ended July 1, 2006 were:

• significantly lower margins from revenue from our top three customers as a result of aggressive pricing from our competitors;

• less absorption of manufacturing overhead expense due to lower production activity during the quarter; and

• increased overhead expense due to a headcount increase of 62, and partially offset by a decrease stock based compensation expense.

We believe that, in a very fast changing and competitive technology market, we will continue to record write downs of excess and obsolete inventory. A significant change in technology can create additional future exposures, particularly in components that have extremely long lead time. We expect to see continued aggressive pricing from our competitors, particularly at our three largest customers. This will likely negatively impact our gross margin in future periods. In addition, gross profit will be impacted by changes in levels of sales because our fixed and semi-variable costs do not vary directly with fluctuations in sales.

Research and development expense. The $3.6 million dollar increase in research and development expenses to support existing products and develop new technologies in the three months ended June 30, 2007 as compared to the three months ended July 1, 2006, consisted primarily of:

• The addition of 15 engineering personnel from the Terrascale acquisition in September 2006, 16 other personnel additions, pay raises, and related recruiting costs resulted in increased compensation of $0.9 million;

21

• Terrascale contingent continued employment bonuses of $1.3 million;

• An increase of $0.7 million in amortization of intangible assets, primarily related to the Terrascale acquisition;

• Facilities, facilities related and depreciation expenses increased $0.3 million, largely driven by Terrascale and other personnel additions; and

• Professional services and consultants expenses incurred to augment our internal engineering staff increased $0.3 million.

The $8.6 million increase in research and development expenses in the six months ended June 30, 2007 as compared to the same period in the prior consisted of:

• The addition of 15 engineering personnel from the Terrascale acquisition in September 2006, 16 other personnel additions, pay raises, and related recruiting costs resulted in increased compensation of $2.0 million;

• Terrascale contingent continued employment bonuses of $2.6 million;

• Stock-based compensation expense related to option grants to Terrascale and other personnel increases added $1.4 million;

• An increase of $1.1 million in amortization of intangible assets, primarily related to the Terrascale acquisition;

• Facilities, facilities related and depreciation expenses increased $0.5 million, largely driven by Terrascale and other personnel additions;

• Professional services and consultants expenses incurred to augment our internal engineering staff increased $0.7 million; and

• Material, expensed small tools and equipment increased $0.5 million.

We expect to continue to increase spending in research and development to support our current products and to develop new products and technologies.

Sales and marketing expense. Sales and marketing expenses increased $2.0 million for the three months ended June 30, 2007 as compared to July 1, 2006. The increase was primarily attributable to the following:

• Headcount increases of seven employees (four related to the Terrascale acquisition), pay raises, and related recruiting costs resulted in increased compensation of $0.7 million. In addition, commission expense increased $0.4 million because of changes to the 2007 commission plan;

• Write downs of evaluation inventory increased $0.3 million due to more evaluation units at customers;

• Expenses related to advertising, trade shows, public relations and consultants to promote product awareness increased $0.4 million; and

• Charges due to stock-based compensation increased $0.3 million largely related to the grants awarded to new employees.

The $5.8 million increase in sales and marketing expenses in the six months ended June 30, 2007 as compared to the same period in the prior year was due primarily to:

• Headcount increases of seven employees (four related to the Terrascale acquisition), pay raises, and related recruiting costs resulted in increased compensation of $1.9 million. In addition, commission expense increased $0.5 million because of changes to the 2007 commission plan;

• Write downs of evaluation inventory increased $0.5 million due to more evaluation units at customers;

• Customer dispute settlement expense of $0.7 million;

22

• Expenses related to advertising, trade shows, public relations and consultants to promote product awareness increased $0.7 million; and

• Charges due to stock-based compensation increased $1.4 million largely related to the grants award to new employees.

We expect that sales and marketing expenses will continue to increase in absolute dollars as we intend to expand our sales force and increase market awareness for our products.

General and administrative expense. General and administrative expense increased $5.0 million for the three months ended June 30, 2007 as compared to July 1, 2006. The increase was due to the following factors:

• Increase in headcount of 14 employees to support our growth and additional public company competencies increased compensation, compensation related and recruiting costs by $0.7 million;

• Accrued severance charges of $0.8 million related to the former CEO and former President;

• Increase of $0.2 million in consulting fees and software and network costs related to infrastructure improvements;

• Depreciation expense increased $0.5 million due to: amortization of leasehold improvements in our new facilities in Fremont, California and amortization of a new ERP system placed into service in August 2006;

• Legal expense increased $0.3 million primarily due to the costs associated with the Super Micro litigation and $0.1 million of professional services;

• A $0.1 million charge related to a customer dispute;

• Increase in the allowance for bad debts by approximately $0.1 million; and,

• Stock-based compensation increased $2.0 million in the three months ended June 30, 2007 as compared to July 1, 2006 due to option grants to new employees and refresher grants to existing employees.

The $12.8 million increase in general and administrative expenses in the six months ended June 30, 2007 as compared to the same period in the prior year was due to the following:

• Increase in headcount of 14 employees to support our growth and additional public company competencies increased compensation, compensation related and recruiting costs $1.3 million which was partially offset by a $0.2 million reduction in management bonuses;

• Accrued severance charges of $0.8 million related to the former CEO and former President;

• An increase of $0.9 million for audit and professional services fees;

• Increase of $0.3 million in consulting fees and software and network costs related to infrastructure improvements;

• Legal expense increased $0.9 million primarily due to the costs associated with the Super Micro litigation;

• A $0.7 million charge related to two customer disputes;

• An accrual of approximately $2.1 million primarily associated with delinquent sales and use tax filings in 17 states, a California sales and use tax audit and an exposure related to sales and use tax for other states;

• Increase in the allowance for bad debts by approximately $0.2 million;

• Increased general insurance expense of $0.1 million due primarily to increased property and inventory exposures;

• Depreciation expense increased $0.7 million due to: amortization of leasehold improvements in our new facilities in Fremont, California and amortization of a new ERP system placed into service in August 2006; and

23

• Stock-based compensation increased $4.6 million in the six months ended June 30, 2007 as compared to July 1, 2006 due to option grants to new employees and refresher grants to existing employees.

We believe that general and administrative expense for the second half of 2007 will be less than during the six months ended June 30, 2007 primarily due to the settlement of SuperMicro litigation and less expenses related to the delinquent sales and use tax filings.

Other income (expense), net decreased in the three months ended June 30, 2007 as compared to the three months ended July 1, 2006 because in the 2006 period we recorded a $0.6 million exchange rate gain from Euro denominated balances we held in our European accounts. Other income (expense), net increased by $0.3 million in the six months ended June 30, 2007 as compared to the same period in 2006 primarily because of increased interest income on the average balances available for investment largely from the proceeds of the secondary offering we completed in March 2006, partially offset by $0.8 million less exchange rate gains on Euro denominated balances in the 2007 period.

Tax provision rate		39.5	%		42.4	%						12.3	%		42.0	%

The income tax provision for the three and six months ended June 30, 2007 includes a $13.2 million charge for an increase in the valuation allowance for deferred tax assets recorded as of the fiscal year ended December 30, 2006. In the three months ended June 30, 2007, we revised our assessment of the realizability of our deferred tax assets due to the significant year-to-date and anticipated losses before income tax provision for the twelve months ended December 29, 2007. We concluded that it was more likely than not that deferred tax assets recorded as of December 30, 2006 in excess of amounts recoverable through loss carry-back would not be realizable. In addition, we recorded tax benefits associated with current fiscal year losses before income tax provision only to the extent of recoverable income taxes. Our tax provision rate as shown above (including discrete charges) for the three and six months ended June 30, 2007 differs from the combined federal and net state statutory income tax rates primarily due to the recording of a valuation allowance for previously recorded and current year deferred tax assets.

Our tax provision rate as shown above for the three and six months ended July 1, 2006, approximated the combined federal and net state statutory income tax rates.

We adopted the provisions of Financial Accounting Standards Board (FASB) Interpretation No. 48,Accounting for Uncertainty in Income Taxes(“FIN 48”), on January 1, 2007 (See Note 6 of our condensed consolidated financial statements).

Liquidity and Capital Resources

Liquidity

Cash and cash equivalents and short-term investments totaled $180.6 million at June 30, 2007, an increase of $20.1 million compared to $160.5 million at December 30, 2006. Cash and cash equivalents totaled $41.9 million at June 30, 2007 and $30.4 million at December 30, 2006.

We expect to finance our operations for the next twelve months primarily through cash, cash equivalents and short term investment balances and cash flow from operations. A large portion of our available cash is invested in highly liquid, short-term investment grade government and agency debt securities and commercial paper with maturities of less than three months.

The following table summarizes our statement of cash flows for the six months ended June 30, 2007 and July 1, 2006:

	Six Months Ended
	June 30, 2007			July 1, 2006
Net cash provided by operating activities	$	30,378		$	9,363
Net cash used in investing activities		(21,512	)		(133,611	)

Cash and cash equivalents—beginning of period		30,446			29,099
Cash and cash equivalents—end of period	$	41,941		$	58,820

Operating Activities

Even though we had a $50.6 million net loss in the six months ended June 30, 2007, net cash provided by operating activities was $30.4 million. This was due to:

• The collection of approximately $230 million of accounts receivable in the six months ended June 30, 2007. The collections in the period consisted of $104 million of our outstanding accounts receivable balance at December 30, 2006 and the remainder was from collections of revenues from sales in the six months ended June 30, 2007.

• Sales in the three months ended December 30, 2006 were very back-end loaded in revenue shipments and sales in the three months ended June 30, 2007 were evenly spread in revenue shipments.

• The net loss in the six months included a significant write down of $20.8 million for excess and obsolete inventory for the six months ended June 30, 2007 and we reduced inventory levels an additional $4.5 million from the December 30, 2006 balance due to lower revenue forecast.

Offsetting the cash from collections of our accounts receivables and the reduction in our inventory, in addition to normal operating expenses, was a reduction in our accounts payable balance at June 30, 2007 as compared to December 30, 2006 by $36.4 million. The reduction in accounts payable occurred because our purchases of inventory in the three months ended December 30, 2006 were much more concentrated at the end of the quarter, contributing to a higher accounts payable balance than we otherwise would have had if our purchases had been more evenly spread throughout the fourth quarter of 2006. Cash provided by, or used in, our operating activities can vary significantly between periods based upon the timing or shipments to customers or receipt of inventory from vendors.

Investing Activities

Cash used by investing activities was $21.5 million for the six months ended June 30, 2007. During the six months ended June 30, 2007, cash used by investing activities consisted of $3.4 million related primarily to the build-out of our new Fremont facility, $9.1 million for the acquisition of the DPE technology and other intangible assets and net purchases of short-term marketable securities of $8.7 million.

25

Financing Activities

Net cash provided from financing activities during the six months ended June 30, 2007 was $2.6 million. The primary source of the cash provided in the six months ended June 30, 2007 was proceeds from the employee stock purchase plan and the exercise of employee stock options.

In order to execute our business strategy, we expect to experience growth in our operating expenses for the foreseeable future. We intend to fund these activities with our cash reserves, available borrowings under our line of credit and cash generated from operations, if any. This increase in operating expenses may not result in an increase in our revenue and our anticipated revenue may not be sufficient to support these increased expenditures. We anticipate that operating expenses and working capital will constitute a material use of our cash resources.

Credit Facility

We have line of credit agreement with a bank that provides for borrowings not to exceed $25.0 million and expires on September 29, 2007. The line of credit agreement contains: financial covenants that specify minimum quarterly profitability of at least $1 in any two consecutive quarters, excluding FAS 123R expense and acquisition related charges; a minimum unencumbered U.S. liquidity; and tangible net worth requirements. Borrowings under the line of credit bear interest, at our option, at prime or adjusted LIBOR plus 185 basis points. There were no borrowings under the line of credit at June 30, 2007. At June 30, 2007, we were not in compliance with the minimum quarterly profitability covenant. On July 31, 2007, the bank waived the minimum quarterly profitability covenant as of June 30, 2007.

Contractual Obligations and Contingent Liabilities and Commitments

The following are contractual commitments at June 30, 2007, associated with debt obligations, lease obligations, and contractual commitments (in thousands):

	Payments due by period
	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
Operating leases	$	10,197	$	1,366	$	3,222	$	3,131	$	2,478
Purchase obligations		82		—		82		—		—
Total	$	10,279	$	1,366	$	3,304	$	3,131	$	2,478

In addition to a five-year lease entered in July 2004 for a building located in Milpitas, California and a three-year lease for an office in Seattle, Washington, we have a seven-year operating lease, commencing on December 1, 2006, for a 117,500-square foot facility which will serve as our manufacturing and warehouse facility in Fremont, California. Lease payments escalate annually and the total future minimum lease payments amount to $6.4 million over the lease term. The stated term of the lease is seven years, but we may extend the lease for an additional three years. As part of this agreement, we are required to maintain a $100,000 cash deposit or an unconditional and irrevocable fully cash-collateralized letter of credit as a form of security. The cash deposit for the lease building is included in other assets in the accompanying condensed consolidated balance sheets as of June 30, 2007.

In November 2006, we signed an additional operating lease for a 40,316-square foot facility which now serves as our headquarters in Fremont, California. Lease payments escalate annually and the total future minimum lease payments amount to $2.6 million over the lease term. The stated term of the lease is six years and ten months, commencing on March 1, 2007. We are required to maintain a cash deposit of approximately $40,000 as part of the lease agreement.

Other than the obligations, liabilities and commitments described above, we have no significant unconditional purchase obligations or similar instruments. We are not a guarantor of any other entities’ debt or other financial obligations. We have no off-balance sheet transactions.

We believe that our current cash balance will be sufficient to meet our needs for at least the next 12 months. If we require additional capital resources to grow our business internally or to acquire complementary technologies and businesses at any time in the future, we may seek to sell additional equity or debt securities or obtain other debt financing. The sale of additional equity or convertible debt securities could result in more dilution to our stockholders. Financing arrangements may not be available to us, or may not be available in amounts or on terms acceptable to us.

Griffiths, a member of our Board of Directors since November 2004, is also President, Products for WebEx Communications, Inc., (“WebEx”), a Cisco Systems, Inc. company, a provider of web-based conferencing solutions. WebEx is a customer of and a supplier us. Revenue from WebEx in the six months ended June 30, 2007 was $222,124 and was $2,297,794 in the six months ended July 1, 2006. At June 30, 2007, $116,215 was outstanding and included in accounts receivable and at December 30, 2006, $10,742 was outstanding and included in accounts receivable.

Risks Related To Our Business and Industry

Our quarterly operating results have fluctuated significantly in the past and will continue to fluctuate in the future, which could cause our stock price to decline.

Our quarterly operating results have fluctuated significantly in the past, and we believe that they will continue to fluctuate in the future, due to a number of factors, many of which are beyond our control. For example, our revenues grew from $80.5 million for the quarter ended September 30, 2006 to $106.9 million for the quarter ended December 30, 2006, declined to revenues of $72.0 million for the quarter ended March 31, 2007, and then increased to $82.2 million for the quarter ended June 30, 2007. Further, our gross margin and net income decreased dramatically in the second quarter of 2007 as a result of a $20.6 million charge we took for excess and obsolete inventory. We expect our revenues, gross margin and earnings per share will fluctuate on a quarterly basis in future periods. If in future periods our operating results do not meet the expectations of investors or analysts who choose to follow our company, our stock price may fall. Factors that may affect our quarterly operating results include the following:

• fluctuations in the buying patterns and sizes of customer orders from one quarter to the next;

• timing of delivery of our products;

• addition of new customers or loss of existing customers;

• gross margin obtained on the sales of products, especially to our largest customers;

• the write-off of excess and obsolete inventory;

• unexpected changes in the price for and the availability of components;

• increased competition causing us to sell our products at decreasing margins;

• our ability to enhance our products with new and better functionality;

• costs associated with obtaining components to satisfy customer demand;

• productivity and growth of our sales force;

• new product announcements or introductions or changes in pricing by our competitors;

• the portion of our revenues that result from the sale of server products and storage products;

• market acceptance of our new products, such as RapidScale and Concentro;

• technology regulatory compliance and intellectual property issues associated with our products;

• the payment of significant damages resulting from faulty or malfunctioning products;

• the departure of key management and other personnel; and

• general economic trends, including changes in information technology spending or geopolitical events such as war or incidents of terrorism.

We are substantially dependent on a concentrated number of customers, specifically Internet companies that purchase in large quantities. If we are unable to maintain or replace our relationships with customers and diversify our customer base, our revenues may fluctuate and our growth may be limited.

Historically, a significant portion of our revenues has come from a limited number of customers. There can be no guarantee that we will be able to sustain our revenue levels from these customers because our revenues have largely been generated in connection with these customers’ decisions to deploy large-scale server and storage farms and their capacity requirements may become fulfilled. In 2005 our three largest customers accounted for approximately 60% of our revenues. In 2006, our two largest customers accounted for 60% of our revenues. In the first half of 2007, our three largest customers accounted for 62% of our revenue. Moreover, the proportion of our revenues derived from a limited number of customers may be even higher in any future quarter. If we cannot maintain or replace the customers that purchase large amounts of our

27

products, or if they do not purchase products at the levels or at the times that we anticipate, our ability to maintain or grow our revenues will be adversely affected. In addition, customer concentration may expose us to credit risk, as a large portion of our accounts receivable may be from a small number of customers. For example, at June 30, 2007, 45% of our accounts receivable were owed to us from three customers.

In 2006 and the first six months of 2007, a substantial majority of our revenues were generated from companies that compete in the internet services market. A significant part of our growth has been due to the fact that these companies are doing well and in many cases expanding, and, as a result, have been purchasing large quantities of products from us. If economic factors change for these Internet companies, as they have before, our ability to maintain or grow our revenues will be adversely affected.

We face intense competition from the leading enterprise computing companies in the world as well as from emerging companies. If we are unable to compete effectively, we might not be able to achieve sufficient market penetration, revenue growth or profitability.

The markets for compute server products and storage products are highly competitive. Our most significant competitors, Dell, Inc., Hewlett-Packard Company, International Business Machines Corporation and Sun Microsystems, Inc. in the compute server market and EMC Corporation, Hewlett-Packard Company, Hitachi Data Systems, Ltd. and Network Appliance, Inc. in the storage market, represent some of the most established companies in the computer industry. These competitors have the following advantages over us:

• substantially greater market presence and greater name recognition;

• substantially greater financial, technical, research and development, sales and marketing, manufacturing, distribution and other resources;

• longer operating histories;

• a broader offering of products and services;

• more established relationships with customers, suppliers and other technology companies; and

• the ability to acquire technologies or consolidate with other companies in the industry to compete more effectively.

Because these competitors have greater financial strength than we do and are able to offer a more diversified bundle of products and services, they may have the ability to severely undercut the pricing of our products, which would make us less competitive or force us to reduce our average selling prices, negatively impacting our margins. In the fourth quarter of 2006, we had a large transaction where a competitor undercut our prices causing us to reduce our price, which negatively impacted our gross margin on that transaction and our overall gross margin for the quarter. In addition, we have on occasion lost sales opportunities due to a competitor undercutting the pricing of our products or maintaining superior brand recognition. These competitors may be able to develop products that are superior to the commercially available components that we incorporate into our products, or may be able to offer products that provide significant price advantages over those we offer. For instance, a competitor could use its resources to develop proprietary motherboards with specifications and performance that are superior in comparison with the platforms that are currently available to the marketplace, which could give that competitor a distinct technological advantage. In addition, if our competitors’ products become more accepted than our products, our competitive position will be impaired.

As the enterprise computing industry evolves, we expect to encounter additional competitors, including companies in adjacent technology businesses such as storage and networking infrastructure and management, companies providing technology that is complementary to ours in functionality, such as datacenter management software, contract manufacturers, and other emerging companies that may announce server product offerings. Moreover, our current and potential competitors, including companies with whom we currently have strategic alliances, may establish cooperative relationships among themselves or with other third parties. If this occurs, new competitors or alliances may emerge that could negatively impact our competitive position.

Our products incorporate open standard, commoditized components and materials that we obtain in spot markets, and, as a result, our cost structure and our ability to respond in a timely manner to customer demand are sensitive to volatility of the market prices for these components and materials.

A significant portion of our cost of goods sold is directly related to the pricing of commoditized materials and components utilized in the manufacture of our products, such as memory, hard drives and central processing units, or CPUs.

28

As part of our procurement model, we do not enter into long-term supply contracts for these materials and components, but instead purchase these materials and components in a competitive bid purchase order environment with suppliers or on the open market at spot prices. As a result, our cost structure is affected by the availability and price volatility in the marketplace for these components and materials, especially for dynamic random access memory, or DRAM, and new versions of hard drives and CPUs that are introduced by our suppliers. In the fourth quarter of 2006, we experienced volatility in DRAM prices that caused us to procure DRAM at prices higher than anticipated, which negatively impacted our overall gross margin for the quarter. In the first half of 2007, prices of DRAM have plummeted. This volatility makes it difficult to predict expense levels and operating results and may cause them to fluctuate significantly. In addition, if we are successful in growing our business, we may not be able to continue to procure components solely on the spot market, which would require us to enter into contracts with component suppliers to obtain these components. This could increase our costs and decrease our gross margins.

In addition, because our procurement model involves our ability to maintain a low inventory and to acquire materials and components as needed, and because we do not enter into long-term supply contracts for these materials and components, we may be in a position in which our ability to effectively and efficiently respond to customer orders may be constrained by the then-current availability or the terms and pricing of these materials and components. Our industry has experienced component shortages and delivery delays in the past, and in the future we may experience shortages or delays of critical components as a result of strong demand in the industry or other factors. As one example, DRAM can represent a significant portion of our cost of revenues, and both the price and availability of various kinds of DRAM are subject to substantial volatility in the spot market. In the past, we have encountered situations where we were forced to pay higher prices than we anticipated for DRAM, which occurred in the fourth quarter of 2006, and we have encountered situations where DRAM was in tight supply and we were unable to deliver customer orders on their anticipated delivery dates. As another example, the industry in the past has experienced a shortage of selected Intel chips, which caused some of our motherboard suppliers to reduce or suspend shipments of motherboards using these chips. This impacted our ability to ship selected configurations to some of our customers, and in some cases accelerated a transition to other platforms. If shortages or delays arise, the prices of these components may increase or the components may not be available at all. We may not be able to secure enough components at reasonable prices or of acceptable quality to build new products to meet customer demand, which could adversely affect our business and financial results.

We intend to expand our operations and increase our expenditures in an effort to grow our business. If we are not able to manage this growth and expansion, or if our business does not grow as we expect, our operating results may suffer.

We intend to continue to grow our business by entering new markets, developing new product and service offerings and pursuing new customers. In connection with this growth, we expect that our annual operating expenses will increase over the next several years as we expand our sales and marketing, research and development, manufacturing and production infrastructure, and our customer service and support efforts. Our failure to timely or efficiently expand operational and financial systems and to implement or maintain effective internal controls and procedures could result in additional operating inefficiencies that could increase our costs and expenses more than we had planned and might cause us to lose the ability to take advantage of market opportunities, enhance existing products, develop new products, satisfy customer requirements, respond to competitive pressures or otherwise execute our business plan. Additionally, if we do increase our operating expenses in anticipation of the growth of our business and this growth does not meet our expectations, our financial results will be negatively impacted.

If we acquire or invest in other companies, assets or technologies and we are not able to integrate them with our business, or we do not realize the anticipated financial and strategic goals for any of these transactions, our financial performance may be impaired.

If appropriate opportunities present themselves, we may consider acquiring or making investments in companies, assets or technologies that we believe are strategic. We only have limited experience in doing so, and if we do succeed in acquiring or investing in a company, asset or technology we will be exposed to a number of risks, including:

• we may find that the acquired company, asset or technology does not further our business strategy, that we overpaid for the company, asset or technology or that the economic conditions underlying our acquisition decision have changed;

• we may have difficulty integrating the assets, technologies, operations or personnel of an acquired company, or retaining the key personnel of the acquired company;

29

• our ongoing business and management’s attention may be disrupted or diverted by transition or integration issues and the complexity of managing geographically or culturally diverse enterprises;

• we may encounter difficulty entering and competing in new product or geographic markets or increased competition, including price competition or intellectual property litigation; and

• we may experience significant problems or liabilities associated with product quality, technology and legal contingencies relating to the acquired business or technology, such as intellectual property or employment matters.

In addition, from time to time we may enter into negotiations for acquisitions or investments that are not ultimately consummated. These negotiations could result in significant diversion of management time, as well as substantial out-of-pocket costs. If we were to proceed with one or more significant acquisitions or investments in which the consideration included cash, we could be required to use a substantial portion of our available cash. To the extent we issue shares of capital stock or other rights to purchase capital stock, including options and warrants, existing stockholders might be diluted and earnings per share might decrease. In addition, acquisitions and investments may result in the incurrence of debt, large one-time write-offs, such as of acquired in-process research and development costs, and restructuring charges.

We have begun to expand our sales into international markets and intend to further expand our sales into additional international markets, which may be more difficult than we expect, and if we are unable to do so successfully, our revenues and operating results may be adversely impacted.

One component of our growth strategy is to expand into international markets, which includes our establishment of subsidiaries in Ireland during September 2005 and in Hong Kong in September 2006. However, we have limited experience in selling our systems overseas, and we may encounter unexpected difficulties in doing so. To date, our sales to these geographies have been primarily originated from our U.S. based multi-national customers. If we are not able to successfully expand into international markets, our ability to grow our business will be adversely affected. Some of the factors that may impact our ability to initiate and maintain sales in foreign markets include:

• our ability to establish international manufacturing, support and service, which could be costly and time consuming;

• our ability to establish channel relationships with resellers in international markets;

• adoption of new laws or changes to existing international laws;

• our ability to service international installations;

• currency fluctuations; and

• political and economic instability.

Our business depends on decisions by potential customers to adopt our modular, open standard-based products and to replace their legacy server systems with our products, and they may be reluctant to do so, which would limit our growth.

Our business depends on companies moving away from large proprietary RISC/UNIX servers, to servers based on modular, open standard-based architecture, including servers that run on Linux and Microsoft Windows operating systems and that utilize commercially available x86 processor architectures. If enterprises do not continue to adopt this open standard-based approach, the market for our products may not grow as we anticipate and our revenues would be adversely affected. Excluding sales to Microsoft Corporation, we believe that a majority of the server systems that we sold in 2005, 2006 and the first half of 2007 ran on the Linux operating system, and are subject to the GNU General Public License. Pending litigation involving the SCO Group’s claim against IBM that Linux is an unauthorized derivative work of the UNIX^® operating system, if it results in a ruling that users of Linux must pay royalties to SCO or others, could impede broader Linux adoption and could materially harm our ability to sell our products based on the Linux operating system. In addition, Microsoft has publicly claimed that Linux infringes 235 or more of Microsoft’s patents and has entered into transactions with Novell inc. and other Linux distributors under which the parties reportedly agree, among other things, not to sue each other’s customers for potential patent infringements related to Linux. It is possible that a party (including Microsoft) could prove a claim for proprietary rights in the Linux operating system or other programs developed and distributed under the GNU General Public License. In addition, the GNU General Public License is a subject of litigation, and it is possible that a court could hold these licenses to be unenforceable in that litigation. Any ruling by a court that the Linux operating system or significant portions of it may not be copied, modified or distributed subject only to the minimal restrictions contained in these licenses, that users or

30

distributors of Linux must pay royalties to Microsoft or others or that these licenses are not enforceable could also impede broader Linux adoption and materially harm our ability to sell our products based on the Linux operating system. Further, because potential customers have often invested significant capital and other resources in existing systems, many of which run mission-critical applications, customers may be hesitant to make dramatic changes to their datacenter systems. The failure of our customers and potential customers to replace their legacy server systems and adopt open standard-based modular technologies could have a material adverse impact on our ability to maintain or generate additional revenues.

We rely primarily on our direct sales force to generate revenues, and may be unable to hire additional qualified sales personnel in a timely manner or retain our existing sales representatives.

To date, we have relied primarily on our direct sales force to sell our products in the United States. Because we are looking to expand our customer base and grow our sales to existing customers, we will need to continue to hire qualified sales personnel if we are to achieve our anticipated revenue growth. The competition for qualified sales personnel in our industry, and particularly in Silicon Valley, is very intense. If we are unable to hire, train, deploy and manage qualified sales personnel in a timely manner, our ability to grow our business will be impaired. For example, in the past it has taken us up to six months to hire a qualified sales executive and it may take a newly-hired sales executive up to nine months after hiring to become productive, resulting in aggregate lag time between the commencement of the search to productivity in excess of one year. In addition, if we are unable to retain our existing sales personnel, our ability to maintain or grow our current level of revenues will be adversely affected. In addition, a large percentage of our revenue is generated from a small number of customers. If we are unable to retain the sales personnel who are responsible for those customer accounts, our business could be negatively impacted.

We are developing a channel strategy to generate additional sales and revenues, and the failure to implement this strategy successfully might affect our ability to sustain revenue growth and may harm our business and operations.

An increasing portion of our sales strategy is to develop our sales efforts through the use of resellers and other third parties to sell our systems. We may not be successful in building or expanding relationships with these third parties. Further, even if we do develop and expand these relationships, they may conflict with our direct sales efforts in some territories. Ineffective marketing of our products by our resellers or disruptions in our distribution channels could lead to decreased sales or slower than expected growth in revenues and might harm our business and operations.

Our sales cycle requires us to expend a significant amount of resources, and could have an adverse effect on the amount, timing and predictability of future revenues.

The sales cycle of our products, beginning from our first customer contact to closing of the sale, often ranges from three to six months. We may expend significant resources during the sales cycle and ultimately fail to close the sale. The success of our product sales process is subject to factors over which we have little or no control, including:

• the timing of our customers’ budget cycles and approval processes;

• our customers’ existing use of, or willingness to adopt, open standard server products, or to replace their existing servers or expand their processing capacity with our products;

• the announcement or introduction of competing products; and

• established relationships between our competitors and our potential customers.

We expend substantial time, effort and money educating our current and prospective customers as to the value of our products. Even if we are successful in persuading lower-level decision makers within our customers’ organizations of the benefits of our products, senior management might nonetheless elect not to buy our products after months of sales efforts by our employees or resellers. If we were unsuccessful in closing sales after expending significant resources, our revenues and operating expenses will be adversely affected.

If we are unable to protect our intellectual property adequately, we may not be able to compete effectively.

Our intellectual property is critical to our success and our ability to compete. If we fail to protect our intellectual property rights adequately, our competitors might gain access to our technology. Unauthorized parties may attempt to copy or otherwise obtain and use our proprietary technology despite our efforts to protect our intellectual property. In September 2005, we filed a patent infringement action against one defendant in response to which the defendant counterclaimed that two of our patents are invalid and not infringed. In addition, we previously initiated two patent infringement actions against six defendants, seeking to enforce our intellectual property rights. We obtained consent judgments and permanent injunctions against five of the defendants, and reached a confidential settlement with the sixth.

31

However, litigation is inherently uncertain, and there is no assurance that any litigation we initiate will have a successful outcome. Monitoring unauthorized use of our technology is difficult, and we cannot be certain that the steps we have taken will prevent unauthorized use of our technology, particularly in foreign countries where we have two patent applications pending but do not have any issued patents, and the laws may not protect our proprietary rights as fully as the laws of the United States. Any claims or litigation that we have initiated or that we may initiate in the future to protect our proprietary technology could be time consuming and expensive and divert the attention of our technical and management resources whether or not the claims or litigation are decided in our favor. We currently have a small number of patents issued in the United States and a number of utility patent applications pending. Patents may not be issued from these patent applications, and even if patents are issued, they may not benefit us or give us adequate protection from competing products. For example, issued patents might be circumvented or challenged, as is the case in the current patent infringement action, and could be declared invalid or unenforceable. Moreover, if other companies develop unpatented proprietary technology similar to ours or competing technologies, our competitive position will be weakened.

If we are found to have violated the intellectual property rights of others, we could be required to indemnify our customers, resellers or suppliers, redesign our products, pay significant royalties and enter into license agreements with third parties.

Our industry is characterized by a large number of patents, copyrights, trade secrets and trademarks and by frequent litigation based on allegations of infringement or other violation of intellectual property rights. As we continue our business, expand our product lines and our product functionality, and expand into new jurisdictions around the world, third parties may assert that our technology or products violate their intellectual property rights. Although we have no knowledge of being in infringement, we cannot assure you that we are not in infringement of third party patents. Any claim, regardless of its merits, could be expensive and time consuming to defend against and would divert the attention of our technical and management resources. Successful intellectual property claims against us could result in significant financial liability or prevent us from operating our business or portions of our business. In addition, resolution of claims may require us to redesign our technology, to obtain licenses to use intellectual property belonging to third parties, which we may not be able to obtain on reasonable terms, to cease using the technology covered by those rights, and to indemnify our customers, resellers or suppliers. Any of these events could materially harm our business, financial condition and results of operations.

If we lose the services of one or more members of our current executive management team or other key employees, or if we are unable to attract additional executives or key employees, we may not be able to execute on our business strategy.

Our future success depends in large part upon the continued service of our executive management team and other key employees. We recently had several management changes, including the appointment of our chief executive officer, Mark Barrenechea at the end of April 2007 and departure of our former chief executive officer Tom Barton and our former executive vice president Todd R. Ford. In addition, Gautham Sastri who was our chief operating officer was named executive vice president, RapidScale. Changes in management can be disruptive within a company, which could negatively affect our operations, our culture and our strategic direction. Giovanni Coglitore, our chief technology officer and one of our founders, plays a key role in our future technology and product development and the service and support of our existing customers. All of our employees are “at will” and their employment can be terminated by us or them at any time. The failure of our management team to seamlessly manage the management transition, or the loss of services of any of these executives or of one or more other members of our executive management or sales team or other key employees could seriously harm our business. Competition for qualified executives is intense, particularly in Silicon Valley, and if we are unable to continue expanding our management team or successfully integrate new additions to our management team in a manner that enables us to scale our business and operations effectively, our ability to operate effectively and efficiently could be limited.

If we fail to maintain or expand our relationships with our suppliers, we may not have adequate access to new or key technology necessary for our products, and, as a result, our ability to deliver leading-edge products may be impaired.

In addition to the technologies we develop, our suppliers develop product innovations at our direction that are requested by our customers. In many cases, we retain the ownership of the intellectual property developed by these suppliers. In addition, we rely heavily on our component suppliers, such as Intel and Advanced Micro Devices, to provide us with leading-edge components. If we are not able to maintain or expand our relationships with our suppliers or continue to leverage their research and development capabilities to develop new technologies desired by our customers, our ability to deliver leading-edge products may be impaired and we could be required to incur additional research and development expenses.

32

We depend on our server products for the majority of our revenues. If the market acceptance of our compute server products does not continue, we may not be able to achieve or sustain our anticipated growth.

For fiscal 2006 and 2005, sales of our server compute products accounted for approximately 90% and 90%, respectively, of our revenues. In the first half of 2007, compute server products accounted for approximately 89% of our revenues. If our compute server products fail to maintain market acceptance, or if we are unsuccessful in developing improved products or products to replace or supplement our current server product lines, we may not grow our business and revenues as we expect. Further, because our customers are engaged in large-scale data center implementations, if customers believe that new generations of our products will become available in the near future, this perception may cause customers to delay or cancel existing orders, which would affect our ability to generate revenues in accordance with forecasted levels.

We rely on contract manufacturers to manufacture our products, and our failure to successfully manage our relationships with these contract manufacturers could impair our ability to deliver our systems in a manner consistent with required volumes or delivery schedules, which could damage our relationships with our customers and decrease our revenues.

We rely on a very small number of contract manufacturers to assemble and test a majority of our products. None of these third-party contract manufacturers are obligated to perform services or supply products to us for any specific period, or in any specific quantities, except as may be provided in a particular purchase order. Moreover, none of our contract manufacturers has provided contractual assurances to us that adequate capacity will be available to us to meet future demand for our products. If our contract manufacturers are not able to maintain our high standards of quality, are not able to increase capacity as needed, or are forced to shut down a factory, our ability to deliver quality products to our customers on a timely basis may decline, which would damage our relationships with customers, decrease our revenues and negatively impact our growth.

Our customers require a high degree of reliability in our products and services, and if we cannot meet their expectations our relationships with our customers could be damaged and demand for our products and services will decline.

Because our customers rely on our products and services for their enterprise or mission critical applications, any failure to provide high quality products and reliable services, whether caused by our own failure or failures by our suppliers or contract manufacturers, could damage our reputation and reduce demand for our products and services. In addition, delays in our ability to fill product orders as a result of quality control issues, such as an increase in failure rates or the rate of product returns, may negatively impact our relationships with our customers and harm our revenues and growth.

If we are not able to recover sales and use taxes from past sales to several of our customers, we may have to pay those taxes out of our funds and record an additional charge to our operating results.

In December 2005, we identified potential state sales and use tax liabilities relating to prior year product sales to customers outside of California. At December 30, 2006, we estimated the gross tax liability to the states was $7.2 million which is shown in accrued sales and use tax. Also included in accrued sales and use tax as of December 30, 2006 is $4.2 million related to current sales and use tax payable. We also quantified the exposure relating to interest and estimated collection exposures and, accordingly, recorded a $0.7 million charge to general and administrative expense in the fiscal year ended December 30, 2006. For the six months ended June 30, 2007, the $7.2 million estimated gross tax liability was decreased by payments of $6.5 million, and increased by $0.7 million related to net accruals, to $1.4 million which was recorded in accrued sales and use tax. The increase in the estimated gross tax liability was a result of additional information received during the quarter relating to customers and their self assessment process. Accrued sales and use tax of $9.3 million includes current sales and use tax payable of $6.9 million in addition to the $1.4 million liability discussed above and accruals of $0.7 million and $0.3 million of sales and use tax related to a California and Washington sales and use tax, respectively. We received an initial estimated assessment in the six month ended June 30, 2007 related to its California Sales Tax audit. We also recorded a $1.9 million charge to general and administrative expense in the first half of 2007 related to additional accruals related to the prior year sales and use tax liabilities, California sales and tax audit and a reserve for Washington sales tax. We believe that we will recover certain sales tax from our customers, and accordingly have recorded a receivable for $5.0 million which is included in other current assets as of June 30, 2007.

33

Maintaining and improving our financial controls and the requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified board members.

We are subject to the reporting requirements of the Securities Exchange Act of 1934 or the Exchange Act, the Sarbanes-Oxley Act of 2002 and The NASDAQ Stock Market Rules. The requirements of these rules and regulations will increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly and may also place undue strain on our personnel, systems and resources. The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and financial condition.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. This can be difficult to do. For example, in connection with our audit for the years ended January 3, 2004 and January 1, 2005, our independent registered public accounting firm noted a reportable condition with respect to the method of accounting that we applied to the embedded derivatives related to our mandatorily redeemable preferred stock, the preferred stock issued to two executives in exchange for promissory notes and certain stock options. As a result, audit adjusting entries were required for the years ended January 3, 2004 and January 1, 2005. Due to the magnitude of the adjustments, this reportable condition was determined to be a material weakness. The accounting for equity and derivative instruments is complex, and the relevant accounting implications must be closely monitored, researched and evaluated. In order to maintain and improve the effectiveness of our disclosure controls and procedures and internal control over financial reporting, significant resources and management oversight are required. As a result of this and similar activities, management’s attention may be diverted from other business concerns, which could have a material adverse effect on our business, financial condition and results of operations. In addition, if we are unable to continue to meet these requirements, we may not be able to remain listed on the NASDAQ Global Select Market.

In connection with these efforts, we implemented a new Enterprise Resource Planning, or ERP System in 2006. If we are unable to effectively use the new ERP System and fail to implement Sarbanes-Oxley compliance-related activities in a timely and efficient manner, management’s attention may be diverted from other business concerns and we may encounter difficulties in accurately reporting on our financial performance on a timely basis, either of which could have a material adverse effect on our business, financial condition and results of operations.

Under the Sarbanes-Oxley Act and NASDAQ rules, we are required to maintain an independent board. If we are unable to maintain adequate directors’ and officers’ insurance, our ability to recruit and retain qualified directors, especially those directors who may be deemed independent for purposes of NASDAQ rules, and officers will be significantly curtailed.

ITEM 3. Quantitative and Qualitative Disclosures About Market Risk

Interest rate risk represents the risk of changes in value of a financial instrument caused by fluctuations in interest rates. We had no borrowings under our line of credit as of June 30, 2007. The annual interest rate on our credit facility is at prime or adjusted LIBOR plus 185 basis points. If and when we do enter into future borrowing arrangements or borrow under our existing revolving credit facility, we may seek to manage exposure to interest rate changes by using a mix of debt maturities and variable- and fixed-rate debt, together with interest rate swaps where appropriate, to fix or lower our borrowing costs. We do not make material sales or have material purchase obligations outside of the United States and therefore do not generally have exposure to foreign currency exchange risks.

Our exposure to market risks for changes in interest rates relates primarily to our investment portfolio. As of June 30, 2007, our cash equivalents consisted of money market funds in the amount of $31 million, and our short-term investments consisted of $138.7 million of debt securities with effective maturities of three months or less. As of December 30, 2006, our cash equivalents consisted of money market funds in the amount of $30.4 million, and our short-term investments consisted of $130.0 million of debt securities with effective maturities of three months and less. We do not hold short-term investments for trading purposes. We do not believe that an immediate 10% increase in interest rates would have a material effect on the fair market value of our portfolio at December 30, 2006 and June 30, 2007. Since we believe we have the ability to liquidate this portfolio, we do not expect our operating results or cash flows to be materially affected to any significant degree by a sudden change in market interest rates on our investment portfolio. As of December 30, 2006 and June 30, 2007, we had minimal exposure on value added tax receivables denominated in the Euro.

ITEM 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. As required by Exchange Act Rule 13a-15(b), as of the close of the quarter ended June 30, 2007, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and our operation of our disclosure controls and procedures as defined in Rule 13a-15(e). Disclosure controls and procedures are controls and procedures designed to ensure that the information required to be disclosed by us in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission rules and forms, including, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934 is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Based upon that evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures are effective at the reasonable assurance level as of June 30, 2007.

Changes in Internal Control over Financial Reporting. There was no change in our internal control over financial reporting during the quarter ended June 30, 2007, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

In September 2005, we filed suit against Super Micro Computer, Inc. in the United States District Court for the Northern District of California, claiming that Super Micro infringed two patents held by us. On May 1, 2007, we entered into a confidential settlement agreement with Super Micro and the case was dismissed on May 3, 2007. From time to time, we may be subject to various claims and legal actions arising in the ordinary course of business. We previously discussed this suit in our Annual Report on Form 10-K for the year ended December 30, 2006 and in our Quarterly on Form 10-Q for the quarter ended April 1, 2007. From time to time, we may be subject to various claims and legal actions arising in the ordinary course of business.

ITEM 1A. Risk Factors

We include in Part I, Item 2. “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Risks Related to Our Business and Industry” a description of risk factors related to our business in order to enable readers to assess, and be appropriately apprised of, many of the risks and uncertainties applicable to the forward-looking statements made in this Quarterly Report on Form 10-Q. We do not claim that the risks and uncertainties set forth in that section are all of the risks and uncertainties facing our business, but do believe that they reflect the more important ones.

The risk factors set forth in Part I, Item 1A of our Annual Report on Form 10-K for the year ended December 30, 2006, as filed with the SEC on February 28, 2007, have not substantively changed, except for as follows:

1. The risk factors in Part I, Item 2 have been updated to include financial information for the second quarter of 2007;

2. The risk factor “Our quarterly operating results have fluctuated significantly in the past and will continue to fluctuate in the future, which could cause our stock price to decline” has been updated to present additional examples of factors that could cause our operating results to fluctuate and includes information regarding significant charge for excess and obsolete inventory recorded in the second quarter of 2007;

3. The risk factor “If we are unable to protect our intellectual property adequately, we may not be able to compete effectively” has been updated to reflect the settlement of a patent litigation case;

4. The risk factor “if we lose the services of one or more members of our current executive management team or other key employees, or if we are unable to attract additional executives or key employees, we may not be able to execute on our business strategy” has been revised to reflect recent management changes including the departure of our former CEO and President and the appointment of Mark J. Barrenechea as our new CEO;

5. Since we are no longer separately report the amount of revenue recognized from the sales of our Foundation Series server products, the risk factor “We depend on our Foundation Series servers for the majority of our revenues. If the market acceptance of our Foundation Series servers does not continue, we may not be able to achieve or sustain our anticipated growth” has been modified to discuss our dependence on the sale and market acceptance of all of our server product lines; and

6. The risk factor “Our business depends on decisions by potential customers to adopt our modular, open standard-based products and to replace their legacy server systems with our products, and they may be reluctant to do so, which would limit our growth” has been updated to reflect recent activity regarding Linux litigation and potential litigation.
