functional currency for its Ireland and Hong Kong subsidiaries and therefore re-measurement of its financial statements is not required. Currency transaction gains (losses) are recognized in current operations resulting from translating its
financial statements at the reporting date. The Company uses the Canadian dollar as its functional currency for its Canada subsidiary. Assets and liabilities denominated in non-U.S. dollars are re-measured into U.S. dollars at the rates of exchange
in effect at the balance sheet dates. Revenue and expenses are translated at average exchange rates in effect during each period. Translation adjustments are included in stockholders equity in the consolidated balance sheet as a component of
accumulated other comprehensive income (loss).

Use of Estimates. The preparation of financial statements in accordance
with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the Companys consolidated financial statements and accompanying notes. Management bases its estimates on historical experience and various
other assumptions believed to be reasonable. Although these estimates are based on management's best knowledge of current events and actions that may impact us in the future, actual results may be different from the estimates. The Companys
critical accounting policies are those that affect the Companys financial statements materially and involve difficult, subjective or complex judgments by management. Those policies are revenue recognition, inventory valuation, warranty,
share-based compensation, intangible assets and accounting for income taxes.

Cash and Cash Equivalents. The Company classifies highly
liquid investments as cash equivalents if they do not have a maturity date as of the date of purchase. Cash and cash equivalents consist of cash deposited in checking and money market accounts.

Marketable Securities. The Company accounts for short-term marketable securities in accordance with the Financial Accounting Standards Board
(FASB), Statement of Financial Accounting Standard (SFAS) No. 115, Accounting for Certain Investments in Debt and Equity Securities. The Company classifies marketable securities as available-for-sale at the time
of purchase and re-evaluates such designation as of each consolidated balance sheet date. Our marketable securities

include commercial paper, corporate bond, government securities and auction rate securities. Auction rate securities are securities that are structured with
short-term interest rate reset dates of generally less than ninety days but with contractual maturities that can be well in excess of ten years.

Our marketable securities are reported at fair value with the related unrealized gains and losses included in accumulated other comprehensive income (loss), a component of shareholders' equity, net of tax. Realized gains or losses on the
sale of marketable securities are determined using the specific-identification method and were not material for the three months ended March 29, 2008 and March 31, 2007, respectively. We evaluate our investments periodically for possible
other-than-temporary impairment by reviewing factors such as the length of time and extent to which fair value has been below cost basis, the financial condition of the issuer and our ability and intent to hold the investment for a period of time
which may be sufficient for anticipated recovery of market value. We record an impairment charge to the extent that the carrying value of our available for sale securities exceeds the estimated fair market value of the securities and the decline in
value is determined to be other-than-temporary.

Effective January 1, 2008, the Company adopted the provisions of SFAS No. 157,
Fair Value Measurements (SFAS No. 157), which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements required under other accounting pronouncements. SFAS
No. 157 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. SFAS No. 157 also requires that a
fair value measurement reflect the assumptions market participants would use in pricing an asset or liability based on the best information available. Assumptions include the risks inherent in a particular valuation technique (such as a pricing
model) and/or the risks inherent in the inputs to the model. The adoption of SFAS No.157 did not have a significant impact on our financial statements.

SFAS No.157 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active
markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy under SFAS No. 157 are described below:



| |  |  | Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 2 Quoted prices in markets that are not active or financial instruments for which all significant inputs are observable, either directly or
indirectly; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3 Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable.
| | - |  | --------------------------------------------------------------------------------------------------------------------------

A financial instruments level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

Further information about the application of SFAS No. 157 may be found in Note 11 below.

Accounts Receivable. Accounts receivable are recorded at the invoiced amount and do not bear interest. Our accounts receivable have been reduced by an
allowance for doubtful accounts, which is our best estimate of the amount of probable credit losses in our existing accounts receivable. We determine the allowance based on customer specific experience and the aging of our receivables, among other
factors.

Inventories. Inventories, consisting primarily of server chassis, hard drives, microprocessors, memory chips, cooling fans and
other equipment used in the manufacture of networking servers, are stated at the lower of first-in, first-out cost or market. Cost components include materials, labor and manufacturing overhead costs.

We assess the valuation of our inventory, including demonstration inventory, on a quarterly basis based upon estimates about future demand and actual
usage. To the extent that we determine that we are holding excess or obsolete inventory, we write down the value of our inventory to its net realizable value. Such write-downs are reflected in cost of revenue.

##### Table of Contents

In our inventory valuation analysis, we also include inventory that we could be obligated to purchase
from our suppliers based on our production forecasts. To the extent that our committed inventory purchases exceed our forecasted production needs, we write down the value of those inventories by taking a charge to our cost of products and increasing
our supplier liability.

Property and Equipment. Property and equipment are stated at cost and are depreciated on a straight-line basis over
their estimated useful lives (generally two to seven years). Leasehold improvements and assets acquired under capital leases are amortized using the straight-line method over the shorter of the estimated useful lives of the respective assets or the
lease term. When assets are retired or disposed of, the assets and related accumulated depreciation and amortization are removed from our general ledger and the resulting gain or loss is reflected in the statement of operations.

Maintenance and repairs are charged to expense as incurred and improvements and betterments that enhance the life of the asset are capitalized. When
assets are retired or otherwise disposed of, the cost and accumulated depreciation and amortization are removed.

Intangible Assets. The
Company accounts for intangible assets in accordance with SFAS No. 142 Goodwill and Other Intangible Assets, (SFAS No. 142). The Company periodically evaluates its intangible assets. Intangible assets are carried at cost
less accumulated amortization. Amortization is computed using the straight-line method over the economic lives of the respective assets, generally two to seven years.

The process of evaluating the potential impairment of intangibles is highly subjective and requires significant judgment. We estimate expected future cash flows then compare the carrying value of intangibles to the
discounted future cash flows. If the total of future cash flows is less than the carrying amount of the assets, we recognize an impairment loss based on the excess of the carrying amount over the fair value of the assets.

Impairment of Long-Lived Assets. The Company accounts for its long-lived assets in accordance with SFAS No. 144, Accounting for the Impairment or
Disposal of Long-Lived Assets (SFAS No. 144). The Company evaluates its long-lived assets for indicators of possible impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets
may not be fully recoverable. An impairment loss would be recognized when undiscounted future cash flows expected to result from the use of an asset and its eventual disposition are less than its carrying amount. Impairment, if any, is measured
using discounted cash flows.

Revenue Recognition. The Company accounts for its revenues under the provisions of Staff Accounting Bulletin
(SAB) No. 104, Revenue Recognition in Financial Statements(SAB No. 104), FASB Technical Bulletin No. 90-1, Accounting for Separately Priced Extended Warranty and Product Maintenance Contracts
(FTB 90-1) and Statement of Position No. 97-2, Software Revenue Recognition(SOP 97-2).

Under the
provisions of SAB No. 104, the Company recognizes revenues from sales of products when persuasive evidence of an arrangement exists, shipment has occurred and title has transferred, the sales price is fixed and determinable, collection of the
resulting receivable is reasonably assured, and all significant obligations have been met. Generally, this occurs at the time of shipment when risk of loss and title has passed to the customer.

Service revenue includes hardware maintenance and installation. Pursuant to SAB No. 104, the Company recognizes revenue from the sale of its
products prior to completion of these services, as the Companys product sales are not dependent on these services to be functional. Under FTB 90-1, revenue from hardware maintenance contracts, which are sold and invoiced separately, is
recognized ratably over the contract term, generally one to three years. Installation services are typically requested by the Companys new customers who have limited history with the products. Installation and related services are usually
performed within one day after product delivery.

Where software is integrated with hardware and sold as a hardware appliance the Company
provides unspecified software updates and enhancements to the software through service contracts. As a result, the Company accounts for revenue in accordance with SOP 97-2 for transactions involving the sale of software. Revenues earned on software
arrangements involving multiple-elements are allocated to each element based on Vendor Specific Objective Evidence ("VSOE") of fair value. The VSOE of fair value of the undelivered elements (maintenance and support services) is generally determined
based



8



---

##### Table of Contents

on the price charged for the undelivered element when sold separately or renewed. If VSOE cannot be obtained to determine fair value of the undelivered
elements, revenue from the entire arrangement would be deferred and recognized as these elements are delivered.

On occasion, when a
customer informs the Company that a product is defective, the Company will ship a replacement product at the customers request prior to the customer returning the defective product for repair. This enables the customer to use the replacement
product until the defective product is repaired and returned to the customer. Generally, the Company does not charge for this service unless the customer fails to return the defective product, in which case the customer is billed for the replacement
product and revenue is recognized at that time.

Estimated sales returns and warranty costs, based on historical experience, changes in
customer demand, and other factors, are recorded at the time product revenue is recognized in accordance with SFAS No. 48, Revenue Recognition When Right of Return Exists and SFAS No. 5, Accounting for Contingencies,
respectively.

Deferred Revenue. Deferred revenue is primarily comprised of extended warranty, revenue deferred for installations yet to
be completed, and advanced billing and customer deposits for service, support and maintenance agreements as well as product revenue for which performance obligations or customer acceptance is required. Deferred revenue is recorded when products or
services provided are invoiced prior to the Companys completion of the related performance obligations or customer acceptance. Deferred revenue is not recognized as revenue until the completion of those performance and acceptance criteria.
Extended warranty and service support and VSOE deferrals are recognized ratably over the prerequisite service period.

Product Warranty. The
Companys warranty period for its products is generally one to three years. The Company accrues for estimated warranty costs concurrent with the recognition of revenue. The initial warranty accrual is based upon the Companys historical
experience and is included in accrued expenses and cost of revenue.

Share-based Compensation.The Company accounts for its employee stock
purchase and stock incentive plans under the provisions of SFAS No. 123 (revised 2004), Share-Based Compensation, (SFAS No. 123R). SFAS No. 123R requires the recognition of the fair value of share-based compensation
in net income. The fair values of the Companys stock options and employee stock purchase plan awards are estimated using the Black-Scholes valuation model. Prior to January 1, 2006, the Company accounted for share-based employee
compensation arrangements in accordance with APB No. 25, Accounting for Stock Issued to Employees, (APB No. 25), and related interpretations, as permitted by FASB Statement No. 123, Accounting for Stock-Based
Compensation, (SFAS No. 123.) Under APB No. 25, compensation cost was recognized based on the difference, if any, between the fair value of the Companys common stock on the date of grant and the amount an employee
must pay to acquire the stock. Compensation cost was recorded in accordance with FIN 28, using the multiple-option approach. Under SFAS No. 123R, compensation expense for those options prior to the adoption of SFAS No. 123R continue to be
expensed on the same basis as they were prior to its adoption, reduced for estimated forfeitures.

Research and Development. Costs
related to research, design and development of our products are charged to research and development expense as they are incurred.

Accounting for Income Taxes. The Company records a tax provision for the anticipated tax consequences of the reported results of operations. In accordance with SFAS No. 109, "Accounting for Income Taxes"
("SFAS No. 109"), the provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the
financial reporting and tax bases of assets and liabilities, and for operating losses and tax credit carry-forwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for
the years in which those tax assets are expected to be realized or settled.

The Company is required to assess the realization of deferred
tax assets and the need for a valuation allowance. This assessment requires that management makes judgments and assesses the weight of positive and negative evidence in accordance with the requirements of SFAS No. 109 for purposes of concluding
whether it is more likely than not that deferred tax assets will be realized. The effective tax rate varies based on a variety of factors, including overall profitability, the geographical mix of income before taxes and the related tax rates in
the jurisdictions where the Company operates, restructuring and other one-time charges, as well as discrete events, such as settlements of future audits. The Company is subject to audits and examinations of tax returns by tax authorities in various
jurisdictions, including the Internal Revenue Service. The Company regularly assesses the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes.

In June 2006, the FASB issued interpretation No. 48, Accounting for Uncertainty in Income Taxes,
an interpretation of FASB Statement No. 109(FIN 48). The Interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to
be taken in a tax return. The Interpretation also provides guidance on de-recognition, classification, interest and penalties, accounting for interim periods, disclosure and transition. FIN 48 was adopted by the Company in the first quarter of
fiscal 2007. The cumulative effect of applying FIN 48 was recorded as an adjustment to retained earnings as of the beginning of the period of adoption. The adoption of FIN 48 did not have a material impact on the Companys consolidated
results of operations, balance sheet and cash flows.

Recently Issued Accounting Pronouncements.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business Combinations (SFAS No. 141(R)). SFAS
No. 141(R) establishes principles and requirements for how an acquirer recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, any non-controlling interest in the acquiree and the goodwill
acquired. SFAS No. 141(R) also establishes disclosure requirements to enable the evaluation of the nature and financial effects of the business combination. SFAS No. 141(R) is effective as of the beginning of an entitys fiscal year
that begins after December 15, 2008. The Company expects to adopt SFAS No. 141(R) in the beginning of fiscal year 2009 and is currently evaluating the potential impact, if any, of the adoption of SFAS No. 141(R) on its consolidated
results of operations and financial condition.

In February 2007, the FASB issued SFAS No. 159,The Fair Value Option for Financial
Assets and Financial Liabilities  Including an Amendment of FASB Statement No. 115,(SFAS No. 159), 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 has
elected not to adopt SFAS No. 159.

3. BALANCE SHEET

Short-and Long-Term Investments

At March 29, 2008 and December 29, 2007, all of the Companys marketable
debt securities were classified as available-for-sale and were carried at fair market value. Auction rate securities are securities that are structured with short-term interest rate reset dates of generally less than ninety days but with contractual
maturities that can be well in excess of ten years. At the end of each reset period, which occurs every seven to thirty-five days, investors can sell or continue to hold the securities at par subject to a successful interest rate reset. In the
first quarter of fiscal year 2008, certain auction rate securities failed auction due to sell orders exceeding buy orders. Our auction rate securities consist of investments that are backed by pools of student loans ultimately guaranteed by the U.S.
Department of Education. We believe that the credit quality of these securities is high based on these guarantees. Based on an analysis of other-than-temporary impairment factors, we recorded a temporary impairment within other accumulated
comprehensive loss of approximately $0.4 million at March 29, 2008 related to these auction rate securities. The Company intends and has the ability to hold these securities until the value of such securities recovers. The funds associated with
failed auctions will not be accessible until a successful auction occurs, a buyer is found outside of the auction process, the underlying securities have matured or the securities are recalled by the issuer. Given the recent disruptions in the
credit markets and the fact that the liquidity for these types of securities remains uncertain, we have classified all of our auction rate securities ($8.7 million, net of unrealized loss), that were not liquidated subsequent to March 29, 2008
as long-term assets in our condensed consolidated balance sheet as our ability to liquidate such securities in the next 12 months is uncertain. The Company utilized the guidance and procedures as provided by SFAS No. 157 in determining the
current fair value. The unrealized gains (losses) on available-for-sale securities are recorded in accumulated other comprehensive income (loss). Short- and long-term investments consisted of the following (in thousands):

In December 2002, as a part of the acquisition of Old Rackable, the Company recorded an intangible
asset allocated to tradename in the amount of $3.5 million. This intangible asset is not amortizable.

Long-lived intangible assets with
determinable economic life are tested for recoverability whenever events or circumstances indicate that their carrying amounts may not be recoverable. The Company determined the recoverability of long-lived intangible assets was not impaired at
March 29, 2008 and December 29, 2007.

4. 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 sets forth the computation of basic and diluted net income (loss) per share (in thousands, except share and per share data):

For the three months ended March 29, 2008 and March 31, 2007 the Company had stock
options outstanding which could potentially dilute basic earnings per share in the future, but the incremental shares from the assumed exercise of these stock options were excluded in the computation of diluted net loss per share, as their effect
would have been anti-dilutive. The number of such outstanding stock options consisted of the following:

5. SHARE BASED COMPENSATION

Share-Based Benefit Plans

In 2005, the Companys Board of Directors adopted and its
stockholders approved the Companys 2005 Equity Incentive Plan (the 2005 Plan), 2005 Non-Employee Directors Stock Option Plan and 2005 Employee Stock Purchase Plan (the 2005 ESPP).

The Companys Board of Directors adopted the 2006 New Recruit Equity Incentive Plan (the New Recruit Plan) in January 2006 which allows
the Company to grant non-statutory stock awards to employees newly hired by the Company as an inducement to join the Company. No grants may be made under the New Recruit Plan to persons who are continuing employees of the Company, or to directors.
The New Recruit Plan provides for the grant of the following stock awards: (i) non-statutory stock options, (ii) stock purchase awards, (iii) stock bonus awards, (iv) stock appreciation rights, (v) stock unit awards, and
(vi) other stock awards.

Adoption of SFAS 123R

On January 1, 2006, the Company adopted the provisions of SFAS 123R requiring the Company to recognize expenses related to the fair value of the Companys share-based compensation awards. The Company elected
to use the modified prospective application method. Under this method, SFAS 123R is applied to new awards and to awards modified, repurchased, or cancelled after the effective date. Additionally, compensation cost for the portion of awards for which
the requisite service has not been rendered (such as unvested options) that was outstanding as of the date of adoption is recognized as the remaining requisite services are rendered. The compensation cost relating to unvested awards at the date of
adoption is based on the grant-date fair value of those awards as calculated for pro forma disclosures under the original SFAS 123. Additionally, under SFAS 123R, the 2005 ESPP is considered a compensatory plan, which requires the recognition of
compensation cost for grants made under the ESPP. The Company recognizes compensation expense for all share-based payment awards over the requisite service period for each separately vesting portion of the award as if the awards were, in-substance,
multiple awards. 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.

Tender Offer

On June 11, 2007, in order to address the lack of retention and incentive effect that the Companys out-of-the-money stock options were having on the Companys employees, the Company filed a
tender offer on Schedule TO (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 unit awards granted under the 2005
Equity Incentive Plan. On June 11, 2007, the closing price per share was $13.23. The tender offer was based upon the following exchange ratios:



|                     |  |                                              
|-------------------- |  | ---------------------------------------------
|Exercise Price Range |  | Stock Options Shares perRestricted Stock Unit
|$16.00$24.99        |  | 2 to 1                                       
|$25.00$34.99        |  | 3 to 1                                       
|$35.00 and above     |  | 3.5 to 1                                     

The restricted stock unit awards are 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 Company completed the Tender Offer
on July 10, 2007. As a result, the Company accepted for exchange options to purchase an aggregate of 2,238,883 shares of the Companys common stock from 187 eligible participants, representing 87% of the shares subject to options that were
eligible to be exchanged in the Offer to Exchange as of May 31, 2007. Upon the terms and subject to the conditions set forth in the Tender Offer to Exchange, the Company issued restricted stock unit awards covering an aggregate of 893,828
shares of the Companys common stock in exchange for the options surrendered pursuant to the Tender Offer to Exchange.

The
fair value of the restricted stock unit awards was measured as the total of the unrecognized compensation cost of the original options tendered and the incremental compensation cost of the restricted stock unit awards on July 10, 2007, the date
of cancellation. The incremental compensation cost was measured as the excess of the fair value of the restricted stock unit awards over the fair value of the options immediately before cancellation based on the share price and other pertinent
factors at that date. The unrecognized compensation cost of the 2,238,883 options cancelled was $17.1 million. The incremental cost of exchange for the 893,828 restricted stock unit awards was approximately $145,000. The total fair value of the
restricted stock unit awards on July 10, 2007 was $17.2 million and the cost will be amortized over the service period of the restricted stock unit awards. The service period of the restricted stock unit awards is longer than the service period
of the options tendered.

Determining Fair Value

The fair value of share-based awards was estimated using the Black-Scholes model with the following weighted-average assumptions for the following periods.

##### Table of Contents

The computation of expected life 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 share-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 Companys pre-vest termination rate, as the Company believes that its historical forfeiture rates are
representative of future expectations.

9. INCOME TAXES

The Company recorded a tax provision of $186,000 for the three months ended March 29, 2008. The effective tax rate used to record the tax provision
differed from the combined federal and net state statutory income tax rate for the three months ended March 29, 2008 due primarily to an increase in the valuation allowance for domestic deferred tax assets.

The Company recorded a tax benefit for the three months ended March 31, 2007 based on a projected 36.8% annual effective tax rate. The effective tax
rate of 36.8% used to record the tax benefit differed from the combined federal and net state statutory income tax rate for the three months ended March 31, 2007 due primarily to certain share-based compensation expenses for which tax benefits
and related deferred tax assets are not recorded in accordance with SFAS 123R.

The Company adopted the provisions of Financial Accounting
Standards Board (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 January 1, 2007. 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) have been recorded in the balance sheet as of December 29, 2007 as Other Long-Term Liabilities.

The
Companys foreign subsidiaries file income tax returns in the countries in which they have operations. Generally, these countries have statutes of limitations ranging from 4 to 6 years. Years still open to examination by foreign tax authorities
in the Companys major filing jurisdiction of Canada are 2003 through 2007. The Companys Canadian subsidiary was recently notified that it will be subject to audit by the Quebec tax authorities for the 2003 to 2005 pre-acquisition tax
years. As of March 29, 2008, there are no unrecorded tax benefits associated with these years that are subject to the tax audit.

Purchase CommitmentsIn connection with supplier agreements, the Company agreed
to purchase certain units of inventory and non inventory items through 2008. As of March 29, 2008, these remaining commitments were approximately $18.9 million and $2.2 million, respectively.

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 were outstanding as of March 29, 2008. 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 March 29, 2008.

11. FAIR VALUE MEASUREMENTS

The financial assets of the Company measured at fair value on a recurring basis are cash equivalents, short-term and long-term investments. The Companys cash equivalents and short-term investments are generally
classified within level 1 of the fair value hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency. The Companys long-term
investments are classified within Level 3 of the fair value hierarchy because they are valued using unobservable inputs, due to the fact that observable inputs are not available, or situations in which there is little, if any, market activity for
the asset or liability at the measurement date.



| |  |  | Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 2: Quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset
or liability; or
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and are unobservable.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------

The following table sets forth the Companys cash equivalents, short- and long-term investments as of
March 29, 2008, which are measured at fair value on a recurring basis by level within the fair value hierarchy. As required by SFAS No. 157, these are classified based on the lowest level of input that is significant to the fair value
measurement.

Exchange Commission on March 13, 2008.

Company Overview

We develop, market and sell compute server, storage systems and data center infrastructure 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. We offer compute servers using our half-depth design, enabling back-to-back
mounting for higher server density and improved thermal management. In August 2004, we expanded our product line of compute servers, which we designed to further increase density levels, improve thermal management, and enhance cable management and
system serviceability. We also offer a number of storage solutions. In the third quarter of 2006, we acquired Terrascale Technologies, Inc. and market its products as our RapidScale storage appliance and in April 2007 we completed our acquisition of
the rights of Distributed Parity Engine (DPE) from the former shareholders of Terrascale. Our RapidScale products provide scalable shared storage solutions. RapidScale permits all stored data to reside under a single namespace and be
simultaneously accessed by thousands of servers. The solution delivers high performance while improving capacity and performance scalability, ease of data management, and capacity utilization. RapidScale appliances leverage our own hardware in
addition to our proprietary RapidScale file system appliance software. In September of 2007, we released the newest generation of our modular data center products, known as ICE Cube, designed to augment or replace traditional
brick-and-mortar data centers of any size and are ideal for data centers facing power and space limitations. We also sell low-cost, high-capacity storage servers, which leverage many of our core compute server technologies, to help enterprises
cost-effectively meet their increasing data storage requirements. Our storage servers represented approximately 19% of our revenue in three months ended March 29, 2008 and 12% for the three months ended March 31, 2007. In addition, we
selectively use reseller and OEM relationships to provide additional compute server and storage offerings that our customers may request from time to time. Service revenues were approximately 3% of total revenues in the three months ended
March 29, 2008 and approximately 2% for the three months ended March 31, 2007.

We market our systems primarily through our
direct sales force predominantly to enterprises within the United States. In the three months ended March 29, 2008 and March 31, 2007, international sales were approximately 7% and 1% of our revenues, respectively. In fiscal 2007,
international sales represented 6% of our total sales. We are 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 500 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.

Share-based Compensation

In July 2007, we completed a tender offer to exchange 893,828 restricted stock unit awards for 2,238,883 employee stock options. (See Note 5 of the
condensed consolidated financial statements.) More than 87% of the eligible employees representing more than 92% of the eligible stock options participated. The incremental accounting charge for the restricted stock unit awards was approximately
$145,000, which reflects the difference between the unrecognized compensation costs of the options cancelled ($17.1 million) and the total value of the restricted stock unit awards on July 10, 2007 ($17.2 million). The total value of the
restricted stock unit awards is amortized over the vesting period of the restricted stock unit awards which is longer than the remaining vesting period of the options tendered.

Beginning with the tender offer discussed above and continuing into 2008, we have moved away from the use of stock option awards and more to the issuance
of restricted stock awards (RSA) and restricted stock units (RSU) for our equity compensation. The following table represents the grants outstanding by type and percent of possible dilution as of the dates set forth below:

The significant reduction in share-base compensation in the three months ended March 29, 2008
is the result of several factors, among them fewer awards outstanding due to the departure of several senior executives, lower fair value at grant date and changes in assumptions in 2008. Changes in the assumptions that are used to calculate expense
were the volatility percentage, which was reduced to 60% in the first quarter of 2008 from 62% during 2007 and the estimated forfeiture rate for unvested awards, which increased to 11.6% in the first quarter of 2008 from 10.5% during 2007. Also
contributing to the reduced expense was the declining grant date fair value over the past year, which results in lower future expense.

Fiscal
Periods

Beginning with the first quarter of calendar 2003, we have a 52-week fiscal year ending on the Saturday nearest to
December 31, with 13 week quarters ending on the last Saturday of the period. The first quarter of our fiscal year 2008 ended on March 29, 2008. The first quarter of our fiscal year 2007 ended on March 31, 2007. Fiscal year 2007 ended
on December 29, 2007.

Critical Accounting Policies

Our critical accounting policies are discussed in our Annual Report on Form 10-K for our fiscal year ended December 29, 2007, and there have been no significant changes.

Significant Judgments and Estimates

The
preparation of financial statements in conformity with US GAAP requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the
financial statements and reported amounts of revenue and expenses. These estimates and judgments are based on historical experience and on various other assumptions that we believe are reasonable under the circumstances, as well as managements
knowledge about current events and expectation about actions that we may undertake in the future. Actual results could differ materially from those estimates.

Results of Operations

The decline in revenue for the three months ended March 29, 2008 as compared to the three
months ended March 31, 2007 was due to timing of customer orders and smaller size purchase commitments, as well as seasonality, that occurred in the first quarter of our fiscal year over the past several years. In the three months ended
March 29, 2008, revenue from our historical top three customers was approximately $26.8 million, or 40% of revenue as compared to $44.6 million, or 62% of revenue, in the three months ended March 31, 2007. The number of units sold in the
three months ended March 29, 2008 declined to approximately 16,831 units as compared to 19,760 units during the same period in 2007. However, the decline in units shipped was partially offset by a 10.8% increase in the average selling price per
unit in the three months ended March 29, 2008 as compared to the three months ended March 31, 2007 due to the change in customer mix and the increased storage revenue as a percent of total revenue. We expect price competition to continue,
particularly in our historical top three accounts, and the future changes in average selling price per unit will largely be dependent upon the customer and product mix.

Gross profit increased approximately $7.0 million due primarily to an $11.0 million decrease in
cost of revenues, partially offset by a $4.0 million decrease in revenue. The decrease in the cost of revenue was primarily due to a decrease of $13.7 million in the cost of materials, partially offset by an increase of $2.3 million related to
excess and obsolete inventory in the quarter. The decrease in the cost of material was the result of better supply chain management and decreases in the prices of commodities during the year, such as memory and motherboards. The increase in excess
and obsolete inventory charges consisted of a $4.5 million charge for excess and obsolete inventory identified in the quarter, offset by $2.2 million from the sale of inventory written down in prior periods.

Changes in customer and product mix and commodity prices, that comprise a significant portion of cost of revenue, significantly impact our gross margin
from period to period. In addition, significant shifts in technology may expose us to excess and obsolete inventory write-downs.

Research and development expense.

The increase in research and development expenses in the three months ended March 29, 2008, as compared to the same period in 2007, was due primarily
to:



| |  |  | The increased compensation and compensation related expenses of $0.9 million was due to the addition of 19 new employees, and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | Amortization expense increased by $0.5 million due primarily to the acquisition of the DPE technology in April 2007.
| | - |  | --------------------------------------------------------------------------------------------------------------------

These increases were offset by the following decreases:



| |  |  | Reduced share-based compensation of $1.1 million due to the changes described in the Company overview under share-based compensation, above and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Lower material expenses of $0.2 million than in the three months ended March 31, 2007 due to lower costs for prototype activities based on the stage of various
development projects
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We expect research and development expense to increase, in absolute dollars, in future periods as
we intend to increase our engineering activities in the areas of storage, remote management and power systems.

Sales and marketing
expense.

The decrease in sales and marketing expenses in the three months ended March 29, 2008 as compared to the three months
ended March 31, 2007, was due to:



| |  |  | Reduced share-based compensation of $1.4 million due to the changes described in the Company overview under share-based compensation, above,
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Decreased commission expense of $0.2 million due to lower revenue and
| | - |  | ---------------------------------------------------------------------



| |  |  | The three months ended March 31, 2007 included, a settlement of a customer dispute that resulted in a $0.7 million charge
| | - |  | -------------------------------------------------------------------------------------------------------------------------

We expect sales and marketing expense to increase, in absolute dollars, in future periods as we expect to expand our sales presence in the United States
and internationally.

General and administrative expense.

The reduction of general and administrative expense in the three months ended March 29, 2008 as compared to the same period in 2007 consisted of the following:



| |  |  | Reduced share-based compensation of $1.6 million due to the changes described in the Company overview under share-based compensation, above,
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Decreased legal expenses of $0.3 million due in large part to resolving the litigation with Super Micro in the three months ended March 31, 2007 which had
associated expenses of $0.8 million, partially offset with $0.5 million higher other legal expenses in the three months ended March 29, 2008,
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The three months ended March 31, 2007 included a $1.9 million expense associated with delinquent sales and use tax filings that were resolved in 2007,
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In the 2007 period, we resolved a customer dispute that resulted in a $0.6 million charge in the period and
| | - |  | -----------------------------------------------------------------------------------------------------------



| |  |  | Reduced expense related to the amortization of intangibles recognized in connection with the Old Rackable transaction became fully amortized in 2007 resulting in
$0.4 million reduction in amortization expense.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These decreases in general and administrative expense in the three
months ended March 29, 2008 as compared to March 31, 2007 were partially offset by:



| |  |  | Increased compensation and compensation related expenses of $0.3 million due to the addition of 8 employees in general and administrative activities
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------

We expect our general and administrative expenses will be relatively constant in terms of absolute
dollars, but may vary as percentage of revenue, for the remainder of the year.

Other income increased primarily due to currency translation gains in the three months ended
March 29, 2008 related to certain receivables which were denominated in Euros. Interest income in the three months ended March 29, 2008 was consistent when compared to the 2007 period, even though our average cash available for investment
was higher in the 2008 period, the lower interest rates resulted in a lower yield.

We recorded a tax provision of $186,000 for the three months ended March 29, 2008. The
effective tax rate used to record the tax provision differed from the combined federal and net state statutory income tax rate for the three months ended March 29, 2008 due primarily to an increase in the valuation allowance for domestic
deferred tax assets.

We recorded a tax benefit for the three months ended March 31, 2007 based on a projected 36.8% annual effective
tax rate. The effective tax rate of 36.8% used to record the tax benefit differed from the combined federal and net state statutory income tax rate for the three months ended March 31, 2007 due primarily to certain share-based compensation
expenses for which tax benefits and related deferred tax assets are not recorded in accordance with SFAS 123R.

Liquidity and Capital Resources

Liquidity

Cash, cash equivalents and investments totaled $206.9 million at March 29,
2008, an increase of $8.8 million compared to $198.1 million at December 29, 2007. 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 following periods (in thousands):

Operating Activities

Cash provided by operating activities was $9.5 million in the three months ended March 29, 2008. Reductions in accounts receivable contributed $15.3 million, as we continued to have strong collection efforts
totaling $89.7 million, combined with the lower revenue, during the period. The reduction in inventory of $14.8 million was the result of better supply chain management efforts, as well reduced inventory levels, as a result of lower revenue during
the period. With reductions in prepaid and others assets contributing an additional $6.7 million, related to lower prepaid taxes, rebates receivable and sales tax receivable during the period. Also contributing was the non-cash item of share based
compensation of $3.5 million. Offset against these increases in cash provided by operations were reductions in account payable of $25.4 million, due in large part to the lower inventory levels as a result of the lower revenue, combined with the
improved supply chain management. As well as accrued and others liabilities of $4.4 million, combined with the net loss of $2.9 million.

Cash provided by operating activities in the three months ended March 31, 2007 was $10.4 million, even though we had a $10.2 million net loss in the three months ended March 31, 2007. The primary contributor to the net cash
provided by operating activities was the collection of approximately $109.0 million of accounts receivable in the quarter. The collections in the three months ended March 31, 2007 consisted of $95.2 million of our outstanding accounts
receivable balance at December 30, 2006 and the remainder was from collections of revenues from sales in the quarter ended March 31, 2007.

Investing Activities

Cash provided by investing activities was $95.4 million for the three months ended
March 29, 2008. Cash provided by investing activities consisted of primarily sales and maturities of our short-term marketable securities of $121.6 million, partially offset by purchases of short-term marketable securities of $25.5 million.

Cash provided by investing activities was $10.3 million for the three months ended March 31, 2007. Cash provided by investing
activities consisted primarily of purchases of short-term marketable securities of $124.3 million, offset by sales and net maturities of our short-term marketable securities of $136.8 million.

In general, we are not a capital intensive company. However, we do expect capital investments to increase moderately in future periods.

Financing Activities

Net cash provided from
financing activities during the three months ended March 29, 2008 was $0.5 million. The primary source of the cash provided was proceeds from the employee stock purchase plan and the exercise of employee stock options.

##### Table of Contents

Net cash provided from financing activities during the three months ended March 31, 2007 was $1.6
million. The primary source of the cash provided 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. 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. Our operating expenses and working capital could constitute a material use of our cash resources. However, we believe our current cash and short-term investments are adequate to support our
funding of our operating expenses and working capital requirements for the next twelve months.

Contractual Obligations and Contingent Liabilities

In connection with agreements with our suppliers, we agreed to purchase certain units of inventory
through 2008. As of March 29, 2008, there was a remaining commitment of $18.9 million through the end of 2008.



|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. If and when we do enter into future borrowing arrangements or borrow under a new 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 March 29, 2008, our cash equivalents consisted of money market funds in the amount of $143.3
million, and our short-term investments consisted of $43.0 million of debt securities with effective maturities of six months or less. We do not hold short-term investments for trading purposes. Our exposure to interest rate changes has not changed
materially since December 29, 2007. 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 March 29, 2008. 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.

At December 29, 2007, we held $64.6 million of short-term investments consisting of various auction rate municipal bonds and variable rate municipal
demand notes (ARS), compared to only $8.7 million, net of unrealized loss of $0.4 million, which are classified as long-term investments as of March 29, 2008. Substantially all of these securities consisted of guaranteed student
loans, insured or reinsured by the federal government.



|ITEM 4. | Controls and Procedures
|------- | -----------------------

Evaluation of
Disclosure Controls and Procedures

Our management, including our chief executive officer and chief financial officer, has evaluated the
effectiveness of our disclosure controls and procedures that are designed to ensure that the information included in reports we file under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is processed and reported within the
appropriate time periods. As discussed in more detail below, our management, including our chief executive officer and chief financial officer, has concluded that these disclosure controls and procedures were ineffective as of March 29, 2008
due to material weaknesses that we identified in our internal control over financial reporting, specifically related to inventory valuation and accounting for income taxes.

##### Table of Contents

As reported in our Annual Report on Form 10-K for our fiscal year ended December 29, 2007, our
management identified two material weaknesses in internal control over financial reporting as of December 29, 2007 as follows:

Inventory
Valuation

Our management concluded that the controls over our accounting for inventory valuation did not operate effectively
as of December 29, 2007. In particular, errors were detected in the inventory valuation for the annual financial statements resulting from: (i) items relating to the calculation of purchase price variances and excess and obsolete inventory
reserve adjustments and; (ii) reviews of inventory valuations not being performed with sufficient precision. Due to the number and magnitude of the errors identified resulting from these internal control deficiencies and the absence of
mitigating controls, management concluded that these internal control deficiencies constitute a material weakness in our internal control over financial reporting because there is a reasonable possibility that a material misstatement of the annual
financial statements would not have been prevented or detected on a timely basis.

Accounting for Income Taxes

Our management concluded that the controls over our accounting for income taxes did not operate effectively as of December 29, 2007. In particular,
errors were detected in the tax calculations for the annual financial statements resulting from: (i) current period tax calculations not being accurately prepared, and (ii) reviews of tax calculations not being performed with sufficient
precision. Due to the magnitude of the error identified resulting from these internal control deficiencies and the absence of mitigating controls, management concluded that these internal control deficiencies constitute a material weakness in our
internal control over financial reporting because there is a reasonable possibility that a material misstatement of the annual financial statements would not have been prevented or detected on a timely basis.

We have been addressing these material weaknesses, as described below; however, management has not tested the internal controls related to the material
weaknesses as disclosed in our Form 10-K, as of December 29, 2007. We do not expect to have fully remediated these material weaknesses, until management has tested those internal controls and found them to have been remediated. We expect to
complete this process during our annual audit for fiscal 2008.

Changes in Internal Control over Financial Reporting

We commenced a number of efforts to remediate the two material weaknesses noted above. These efforts will continue and include the following:

Inventory Valuation

During the
three months ended March 29, 2008, we continued the remediation process commenced last quarter, for the material weakness in accounting for inventory valuation, as reported in Item 9A of our Annual Report on Form 10-K filed March 13, 2008. For
example, we hired, during the period following the filing of our Annual Report, two experienced cost analysts.

As disclosed in Item 9A, we
will continue to make changes as necessary through automation, recruiting and enhancing the training of high quality personnel, in order to provide us with the infrastructure and processes necessary to remediate the inventory valuation material
weakness, and to ensure operating effectiveness and improved internal controls over financial reporting.

Accounting for Income Taxes

During the three months ended March 29, 2008, we continued the remediation process commenced last quarter, for the material weakness in
accounting for income taxes, as reported in Item 9A of our Annual Report on Form 10-K filed March 13, 2008. For example, we recruited, during the period following the filing of our Annual Report, an additional accounting professional to support tax
accounting.

As disclosed in Item 9A, we will continue to make changes as necessary through automation, recruiting and enhancing the
training of high quality personnel, and improving the quality and timing of our accounting close process to allow for increased review time, in order to provide us with the infrastructure and processes necessary to remediate the income tax
accounting material weakness, and to ensure operating effectiveness and improved internal controls over financial reporting.

Inherent Limitation on the Effectiveness of Internal Controls

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise
of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, any system of internal control over financial reporting, including ours, no matter how
well designed and operated, can only provide reasonable, not absolute assurances. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in
conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business, but cannot assure you that such
improvements will be sufficient to provide us with effective internal control over financial reporting.

PART IIOTHER INFORMATION



|ITEM 1A. | Risk Factors
|-------- | ------------

We have updated
the risk factors appearing under the caption Risks Relating to our Business and Industry set forth in our Annual Report on Form 10-K for the year ended December 29, 2007. These updated risk factors are set forth below. We have
designated with an asterisk (*) those risk factors that have changed substantively from those set forth in our Annual Report on Form 10-K. However, there have not been any substantive changes from the risks under the caption Risks
Relating to Owning Our Stock in our Annual Report on Form 10-K for the year ended December 29, 2007, and these risks are not repeated here.

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 increased to $106.9 million for the quarter
ended December 30, 2006, decreased to revenues of $72.0 million for the quarter ended March 31, 2007, increased to $ 111.7 million for the quarter ended December 29, 2007 and decreased to $68.0 million for the quarter ended
March 29, 2008. The decrease in revenue in the first quarter of fiscal 2008 is attributed to a variety of reasons, including seasonality which has occurred in the first quarter of our fiscal year. Further, our gross margin decreased
dramatically in 2007 as a result of competition for the business derived from our principal customers and a $16.6 million charge for excess and obsolete inventory recorded in 2007. We expect that 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;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | increased competition causing us to sell our products or services at decreasing margins;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | location and timing requirements for the delivery of our products and services;
| | - |  | -------------------------------------------------------------------------------



| |  |  | addition of new customers or loss of existing customers, especially involving our largest customers;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | gross margin obtained on the sales of products and services, especially to our largest customers;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | write-off of excess and obsolete inventory;

* 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 2007,
our three largest customers accounted for 64% of our revenues. In the first quarter of 2008, our four largest customers accounted for 68% 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 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, as of March 29, 2008, 64% of our accounts
receivable were owed to us from three customers.

In 2007 and the first quarter of 2008, a substantial majority of our revenues were
generated from companies that compete in the Internet 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. In addition to intensely competitive smaller companies, we face challenges from some of the most established companies in the computer industry, such as Dell, Inc, Hewlett-Packard Company (H-P), International Business
Machines Corporation and Sun Microsystems, Inc in the computer server market. In the storage market, we compete primarily with EMC Corporation, H-P, Hitachi Data Systems, Inc, Super Micro Computer, Inc and Network Appliance, Inc. These larger
competitors have at least 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 may 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 or provide additional products or servicing at little or no cost, which would make us less competitive or force us to reduce our average selling prices, negatively impacting our
margins. In the past, we have had transactions where one or more competitors undercut our prices causing us to reduce our price, which negatively impacted our gross margin on that transaction and our overall gross margin. 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, central processing units (CPUs), or power supplies. As part of our procurement model, we
generally 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 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 2007, prices of DRAM decreased. 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. Also, if we try to take advantage of favorable pricing of a particular component by
purchasing a large quantity, there is the risk that a shift in our customers preferred components may render any stockpiled components of little value to us. For example, we recorded a $16.6 million expense related to the write down for excess
and obsolete inventory during fiscal year 2007, contributed in part by customer driven technology platform shift from AMD to Intel, affecting demand for memory, motherboards, CPUs and chassis that we had previously purchased.

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, 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 fourth quarter of 2006 we encountered
situations where we were forced to pay higher prices than we anticipated for DRAM and we have encountered situations where DRAM was in tight supply and we were unable to deliver customer orders on their anticipated

##### Table of Contents

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. In addition, if any of our suppliers, such as Intel or AMD, were to increase the costs to Rackable for components we use, we would either pass these price increases on to our customers, which
could cause us to lose business from these customers, or we would need to absorb these price increases, which would cause our margins to decrease, either of 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 may increase over the next several years to the extent 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 could be negatively impacted.

If we have acquired or 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 existing or future transactions, our financial performance may be impaired.

If appropriate opportunities present themselves, as they have in the past, 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 for any such company, asset or technology which we successfully acquire or invest in, 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;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

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 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 continue to expand into international markets. 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 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
standardized servers that utilize commercially available x86 processor architectures and can deploy a variety of operating systems, including Linux and Microsoft Windows. Excluding sales to Microsoft Corporation, we believe that a majority of the
server systems that we sold in 2007, 2006 and 2005 ran on the Linux operating system and are subject to the GNU General Public License. While litigation involving the SCO Groups claim against IBM that Linux is an unauthorized derivative work
of the UNIX® operating system has been stayed due to SCOs bankruptcy filing, if it ultimately results in a ruling that users of Linux must pay royalties to SCO or others, that 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 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 commencements of the search to productivity, in excess of one year. We have just hired a new senior vise president of sales and he is in the process of integrating himself into our company. In addition, if we are
unable to retain our existing sales personnel, or if our sales personal are ineffective, 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 continuing to develop and execute upon a channel strategy to generate additional sales and revenues, and the failure to successfully expand channel sales 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,



34

##### Table of Contents

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. For example, 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.

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. These patents may be limited in value in asserting our intellectual property rights against more established companies in the
computer technology sector that have sizeable patent portfolios and greater capital resources. In addition, 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, 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. Any claim,
regardless of its merits, could be expensive and time consuming to defend against. It would also divert the attention of our technical and management resources. Successful intellectual property claims against us could result in significant financial
liability, impair our ability to compete effectively, 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



35

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 negatively affect our competitive position and 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 and enhancement of our executive management team and
other key employees, including, for example, Mark Barrenechea, who joined our company as our chief executive officer, at the end of April 2007. Changes in management can be disruptive within a company, which could negatively affect our operations,
our culture and our strategic direction. 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 employee transitions, 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 or negatively impacted.

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 AMD, 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.

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

Sales of our compute server products accounted for 81% of our revenues during our first quarter of fiscal
2008 and 91% of revenues in fiscal 2007. 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.

* Uncertainty in the credit market may negatively affect the value of auction rate securities owned by us and our
ability to liquidate these securities.

Our investment portfolio as of March 29, 2008, includes various auction rate securities
(ARS) with a cost of $9.1 million. ARS are variable-rate debt securities. While the underlying security has a long-term maturity, the interest rate is reset through Dutch auctions that are held at pre-determined intervals, usually every
28 days. In the past, liquidity for ARS was provided by this auction process that allowed investors to roll over their holdings or obtain immediate liquidity by selling the ARS at market. Recent uncertainty in the credit market has negatively
affected these auctions and certain of these auctions have not had sufficient bidders to allow investors to complete a sale of ARS. In February 2008, auctions related to the $9.1 million of ARS currently owned by us have failed. These are the only
ARS investments in our portfolio as of March 29, 2008. Due to the uncertainty of liquidity, we have classified these investments of $8.7 million as long term and have included such investments in non current assets. We have recorded an
unrealized loss of $0.4 million on such investments to other comprehensive income. In the future, failed auctions for our ARS may affect our ability to liquidate these ARS until a future auction is successful. In addition, failed auctions may affect
the fair value of our ARS and may result in an impairment charge.

Maintaining and improving our financial controls and the requirements of being a
public company may strain our resources and divert managements attention.

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 have increased 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 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. 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

We have material weaknesses in our internal control over financial reporting, and these material weaknesses
create a reasonable possibility of material misstatements in our financial statements.

As a publicly traded company we must maintain
effective disclosure controls and procedures and internal control over financial reporting. This can be difficult to do. In connection with the preparation of our financial statements for the year ended December 29, 2007, we determined that we
had two material weaknesses, and therefore determined that our internal control over financial reporting was not effective, and therefore created a reasonable possibility of material misstatements in our financial statements. These material
weaknesses related to our accounting for inventory valuation and accounting for income taxes, as more fully explained in Part I Item 4. Controls and Procedures in this Quarterly Report on Form 10-Q and have not yet been remediated.

In order to improve and to maintain the effectiveness of our internal control over financial reporting and disclosure controls and
procedures, significant resources and management oversight will be required. We have begun the process of remediating these material weaknesses, but this process will take time, and we will not be able to assert that we have remediated these
material weaknesses until the procedures that we put in place have been working for a sufficient period of time for us to determine that they are effective. 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. If we are unable to remediate these material weaknesses, or in the future report one or more additional material
weaknesses, there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. This could result in a restatement of our financial statements or impact
our ability to accurately report financial information on a timely basis, which could adversely affect our stock price.
