KOMAG, INCORPORATED 
    Note 1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements
have been prepared in accordance with accounting principles generally accepted
in the United States of America for interim financial information and with the
instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they
do not include all of the information and footnotes required by accounting
principles generally accepted in the United States of America. In the opinion
of management, all normal recurring adjustments considered necessary for a fair
presentation of the condensed consolidated financial position, operating
results, and cash flows for the periods presented, have been included.
Operating results for the six months ended July 4, 2004 are not necessarily
indicative of the results that may be expected for the year ending January 2,
2005. Certain reclassifications have been made to prior period balances in order
to conform to the current period presentation. Fiscal Year:The Company uses a 52-53 week fiscal year ending on the
Sunday closest to December 31. Because the Companys 2004 fiscal year will
include 53 weeks, its three-month reporting periods ended April 4, 2004, and
July 4, 2004, included 14 weeks and 13 weeks, respectively. Remaining quarters
of 2004 will include 13 weeks. The Companys three-month reporting periods
ended March 30, 2003 and June 29, 2003 included 13 weeks. Inventories:Inventories are stated at the lower of cost (first-in,
first-out method) or market, and consist of the following (in thousands): July 4, 2004

    25,501
 Stock-Based Compensation:The Company uses the intrinsic value method to
account for employee stock-based compensation. The intrinsic value method is in
accordance with the recognition and measurement principles of Accounting
Principles Board Opinion No. 25, Accounting for Stock Issued to Employees.
Accordingly, compensation cost is recorded on the date of grant to the extent
that the fair value of the underlying share of common stock exceeds the
exercise price for a stock option or the purchase price for a share of common
stock. 6

 For pro forma disclosure purposes, the Company used the Black-Scholes
option pricing model to estimate the fair value of each option and stock
purchase right grant on the date of grant. The following assumptions were used to estimate the fair value of option
grants in the first and second quarters of 2004, and the first quarter of 2003
(there were no grants in the second quarter of 2003): risk-free interest rates
of 2.46% and 3.70%, respectively, for 2004, and 2.68% for 2003; volatility
factors of the expected market price of the Companys common stock of 82.6% and
82.7%, respectively, for 2004, and 87.1% for 2003; and a weighted-average
expected option life of 4.0 years for all periods presented. The
weighted-average fair value of options granted in the first and second quarters
of 2004 and the first quarter of 2003 was $11.58, $8.34, and $4.32,
respectively. The following assumptions were used to estimate the fair value of employee
purchase rights under the Amended and Restated 2002 Employee Stock Purchase
Plan (ESPP) for the first and second quarters of 2004 and 2003: risk-free
interest rates of 1.00% and 1.49%, respectively, for 2004, and 1.18% for each
of the first two quarters of 2003; volatility factors of 73.5% and 70.9%,
respectively, for 2004 and 62.2% for each of the first two quarters of 2003;
and weighted-average expected purchase rights lives of six months for all
periods presented. The weighted-average fair value of those purchase rights

$4.71 in the first and second quarters of 2004,
respectively, and $1.77 in the first and second quarters of 2003. Because the Company does not pay dividends, there was no dividend yield
included in the pro forma disclosure calculation. Net Income Per Share:The Company determines net income per share in
accordance with SFAS No. 128, Earnings per Share. Basic net income per common share is computed by dividing income available
to common stockholders by the weighted-average number of shares of common stock
outstanding during the period. Diluted net income per share is computed by
dividing income available to common stockholders by the weighted-average number
of shares and dilutive potential shares of common stock outstanding during the
period. The dilutive effect of outstanding options and stock purchase rights is
reflected in diluted net income per share by application of the treasury stock
method. The following table reflects the computation of net income per share. The
table is in thousands, except per share amounts. Three Months Ended

 Note 3. Income Taxes The Companys wholly-owned thin-film media operation, Komag USA (Malaysia)
Sdn. (KMS), received an eight-year extension of its tax holiday for its first
plant site in Malaysia. The extension provides a tax holiday through June
2011. The extended tax holiday applies to income generated by sales of disk
products using new technologies. KMS has also been granted additional tax
holidays for its second, third, and fourth plant sites in Malaysia. These tax
holidays expire between December 2006 and 2008. A substantial majority of the
Companys income is generated by sales of disk products covered by
these tax holidays. The Companys estimated annual effective income tax rate for 2004 is 3%,
and includes taxes on income generated by sales of product no longer covered
under the tax holiday at the Companys first Malaysian plant site, and other
tax expenses related to the Companys U.S. and international operations. The Companys income tax provision of $1.0 million and $0.8 million for
the first and second quarters, respectively, of 2003 represented foreign
withholding taxes on royalty and interest payments. In the third quarter of
2003, the Company received approval from the Malaysian Ministry of Finance for
the exemption of withholding tax on royalty payments made by its Malaysian
operations to its subsidiary in the Netherlands. The exemption is for a period
of five years effective retroactively from January 2002 through December 2006.
Therefore, in the first and second quarters of 2003, the Company still had an
accrual for foreign withholding taxes on royalty and interest payments. The
Company reversed the accrual and recorded an income tax benefit of $0.8 million
in the third quarter of 2003. The withholding taxes are no longer payable. In the first quarter of 2004, the Company utilized $1.6 million of
Malaysian capital allowances and net operating loss carry-forwards ($0.5
million tax-effected). The Company did not use any capital allowances or net
operating loss carry-forwards in the second quarter of 2004. Upon emergence
from chapter 11 bankruptcy on June 30, 2002, the Company provided a full
valuation allowance against all tax assets; therefore, upon utilization of the
capital allowance and net operating loss carry-forwards in the first quarter of
2004, the Company made a $0.5 million reduction to intangible assets. The $0.5
million reduction was allocated to reduce the Companys volume purchase
agreement (VPA) with Western Digital 9

##### Table of Contents



Corporation (Western Digital) by $0.3
million and developed technology by $0.2 million. The use of the Companys net operating losses and tax credit
carry-forwards generated by the predecessor company (the Company prior to
emergence from chapter 11 bankruptcy) will be accounted for first as a credit
to intangible assets when they are utilized, and then to additional paid-in
capital after the intangible assets have been reduced to zero. Note 4. Intangible Assets As of July 4, 2004, intangible assets included three items. A VPA of $7.7
million (less accumulated amortization of $4.8 million and tax-related
adjustments of $1.3 million) is included in intangible assets. The VPA is
being amortized on a straight-line basis and has a remaining useful life of
nine months. In addition, developed technology of $3.1 million (less
accumulated amortization of $1.8 million and tax-related adjustments of $0.7
million) is included in intangible assets. The developed technology is being
amortized on a straight-line basis and has a remaining useful life of eighteen
months. Lastly, patent costs of $0.9 million (less accumulated amortization of
$0.2 million) are included in intangible assets. In the first and second quarters of 2004, amortization and adjustments of
intangible assets was $1.1 million and $0.5 million, respectively. In the
first and second quarters of 2003, amortization of intangible assets was $0.9
million. Note 5. Accrued Expenses and Other Liabilities The following table summarizes accrued expenses and other liabilities (in

 Note 6. Debt and Equity Offerings On January 28, 2004, the Company announced the closing of its offering of
$80.5 million of 2.0% Convertible Subordinated Notes (the Notes). The Notes
mature on February 1, 2024, bear interest at 2.0%, and require semiannual
interest payments beginning on August 1, 2004. The Notes will be convertible,
under certain circumstances, into shares of the Companys common stock based on
an initial effective conversion price of $26.40. Holders of the Notes may
convert the Notes into shares of the Companys common stock prior to maturity
if: 1) the sale price of the Companys common stock equals or exceeds $31.68
for at least 20 trading days in any 30 consecutive trading day period within
any fiscal quarter of the Company; 2) the trading price of the Notes falls
below a specified threshold prior to February 19, 2019; 3) the Notes have been
called for redemption; or 4) specified corporate transactions (as described in
the 10

offering prospectus for the notes) occur. As of July 4, 2004, none of the
preceding conditions had been met; therefore, the debt was not convertible.
The Company may redeem the Notes on or after February 6, 2007, at specified
declining redemption premiums. Holders of the Notes may require the Company to
purchase the Notes on February 1, 2011, 2014, or 2019, or upon the occurrence
of a fundamental change, at a purchase price equal to 100% of the principal
amount of the Notes, plus accrued and unpaid interest. There are no financial covenants, guarantees, or collateral associated
with the Notes. In connection with the issuance of the Notes, the Company
incurred $3.1 million of loan fees. The loan fees, which are included in other
assets on the condensed consolidated balance sheet, are being amortized on a
straight-line basis over the 20-year life of the Notes. On July 4, 2004,
unamortized loan fees were $3.0 million. On January 28, 2004, the Company sold 3,525,000 shares of its common stock
at $20.00 per share. The proceeds from the sale of the common stock, net of
$4.1 million of issuance costs, were $66.4 million. The combined net proceeds from the issuance of the Notes and the common
stock were $143.8 million. In February 2004, the Company used the proceeds from the January 2004 debt
and equity offerings to repay in full $116.3 million of previously outstanding
Senior Secured Notes and certain other promissory notes. The previously
outstanding debt bore a weighted-average interest rate of 9.5%. There was no
gain or loss recognized on the repayment of the debt. Additionally, the
Company terminated an unused credit facility with limited borrowing
availability in January 2004. Note 7. Asset Purchase In February 2004, the Company purchased a Malaysian substrate
manufacturing facility for $10.0 million from Trace Storage Technology
Corporation (Trace). The purchase included land, building, and equipment. The
Company is manufacturing aluminum ground substrates and plated and polished
substrates in this factory for its own use. Additionally, the Company is
selling a portion of the output to Trace under a supply agreement entered into
in connection with the purchase. 
 ITEM 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion should be read in conjunction with the condensed
consolidated financial statements and the accompanying notes included in Part
I., Financial Information, Item 1. Condensed Consolidated Financial Statements
of this report. The following discussion contains predictions, estimates, and other
forward-looking statements that involve a number of risks and uncertainties
about our business. These statements may be identified by the use of words such
as expects, anticipates, intends, plans, and similar expressions. In
addition, 11

##### Table of Contents



forward-looking statements include, but are not limited to, statements
about our beliefs, estimates, or plans about our ability to maintain low
manufacturing and operating costs and costs per unit, our ability to estimate
revenues, shipping volumes, pricing pressures, returns, reserves, demand for
our disks, selling, general, and administrative expenses, taxes, research,
development, and engineering expenses, spending on property, plant, and
equipment, expected sales of disks and the market for disk drives generally and
certain customers specifically, and our beliefs regarding our liquidity needs. The Companys business is subject to a number of risks and uncertainties.
While this discussion represents our current judgment on the future direction
of our business, these risks and uncertainties could cause actual results to
differ materially from any future performance suggested herein. Some of the
important factors that may influence possible differences are continued
competitive factors, technological developments, pricing pressures, changes in
customer demand, and general economic conditions, as well as those discussed
below in Risk Factors. We undertake no obligation to update forward-looking
statements to reflect events or circumstances occurring after the date of such
statements. Readers should review Risk Factors below, as well as other
documents filed by the Company with the Securities and Exchange Commission from
time to time. Results of Operations Overview Our net sales are driven by the level of demand for disks by disk drive
manufacturers and the average selling prices of our disks. Demand for our disks
is dependent on unit growth in the disk drive market, the growth of storage
capacity in disk drives, which affects the number of disks needed per drive,
and the number of disks our customers purchase from external suppliers. Average
selling prices are dependent on overall supply and demand for disks and our
product mix. Our business is capital-intensive and is characterized by high fixed
costs, making it imperative that we sell disks in high volume. Our contribution
margin per disk sold varies with changes in selling price, input material costs
and production yield. As demand for our disks increases, our total contribution
margin increases, improving our financial results because we do not have to
increase our fixed cost structure in proportion to increases in demand and
resultant capacity utilization. Conversely, our financial results deteriorate
rapidly when the disk market worsens and our production volume decreases. Because our 2004 fiscal year will include 53 weeks, our three-month and
six-month reporting periods ended July 4, 2004, included 13 weeks and 27 weeks,
respectively. Our three-month and six-month reporting periods ended June 29,
2003, included 13 weeks and 26 weeks, respectively. Net Sales Consolidated net sales of $101.1 million in the second quarter of 2004
were 4.0% lower compared to $105.3 million in the second quarter of 2003.
Finished unit sales volume declined, to 15.1 million units in the second
quarter of 2004 from 16.3 million units in the second quarter of 2003. The
volume decrease 12

##### Table of Contents



was somewhat offset by an increase in the finished unit average selling
price, to $5.80 in the second quarter of 2004 from $5.67 in the second quarter
of 2003. Other disk sales (which generally include single-sided disks, aluminum
substrate disks, plated disks, textured disks, and polished disks) in the
second quarter of 2004 were $13.4 million, compared to $13.7 million in the
second quarter of 2003. Consolidated net sales in the first half of 2004 increased by $13.8
million, to $224.7 million in the first half of 2004 from $210.9 million in the
first half of 2003. The increase was driven by increases in our sales volume
and finished unit average selling price. Our sales volume increased by 3.9%,
to 34.3 million units in the first half of 2004 from 33.0 million units in the
first half of 2003. Our finished unit average selling price increased, to
$5.88 in the first half of 2004 from $5.62 in the first half of 2003. Other disk sales in the first half of 2004 were $23.0 million, compared to
$26.1 million in the first half of 2003. The finished unit shipment increase in the first half of 2004 compared to
the same period in 2003 resulted from a combination of an additional fiscal
week in the first quarter of 2004, an overall improvement in industry
conditions, and an expansion of our customer base. The finished unit average
selling price improvement in the second quarter and first half of 2004 compared
to the same periods in 2003 primarily reflected the transition to higher
capacity product offerings for desktop and consumer applications and disk
shipments for high-end server (enterprise) drives. In the third quarter of 2004, we expect flat net revenue, compared to the
second quarter of 2004. In the second quarter of 2004, sales to Maxtor Corporation (Maxtor),
Hitachi Global Storage Technologies (HGST), Seagate Technology (Seagate),
Western Digital, and IBM accounted for 50%, 30%, 8%, 6%, and zero,
respectively, of our revenue. In the second quarter of 2003, sales to Maxtor,
HGST, Seagate, Western Digital, and IBM accounted for 38%, 11%, zero, 39%, and
12% respectively, of our revenue. We expect to continue to derive a
substantial portion of our sales from Maxtor, HGST, Seagate, and Western
Digital. Sales of 80GB per platter disks increased to 83% of net sales in the
second quarter of 2004, compared to 20% in the same period of 2003. The
increase reflected the continued customer migration to higher storage
densities. All of our customers completed the transition from 40 GB to 80 GB
programs in the first quarter of 2004. Finished disk shipments for desktop and consumer applications together
represented 88% of our second quarter of 2004 unit shipment volume. The
remaining finished disk shipments (12%) in the second quarter of 2004 were
disks for high-end server (enterprise) drives. 13

##### Table of Contents



Gross Profit For the second quarter of 2004, our overall gross profit percentage was
21.4%, a 0.3 point decline compared to a gross profit percentage of 21.7% for
the second quarter of 2003. Lower sales and production, as well as annual
preventive maintenance costs, resulted in a higher fixed cost per disk, which
accounted for a 2.1 point decline. However, the cost per disk increase was
partially offset by an increase in our finished unit average selling price (as
discussed above), which resulted in a 1.8 point increase. For the first half of 2004, we achieved a gross profit percentage of 26.1%
compared to a gross profit percentage of 21.6% for the first half of 2003, a
4.5 point increase. The economies of scale associated with higher sales and
production volumes (as discussed above) lowered our fixed cost per disk, and
accounted for 1.0 point of the gross profit percentage increase in the first
half of 2004. Additionally, an increase in the finished unit average selling
prices (as discussed above), accounted for the remaining 3.5 point increase
in the gross profit percentage in the first half of 2004. We expect to maintain our variable cost per unit at levels similar to the
first half of 2004 while continuing to advance our technology. Our fixed cost
per unit is dependent on the production levels we achieve. Research, Development, and Engineering Expenses Research, development, and engineering (R&D) expenses of $9.0 million in
the second quarter of 2004 were $1.4 million lower compared to the $10.4
million in the second quarter of 2003. The decrease primarily reflected lower
spending and lower incentive compensation expense in the second quarter of 2004
compared to the second quarter of 2003. R&D expenses of $20.7 million in the first half of 2004 were $0.4 million
higher than the $20.3 million in the first half of 2003. The increase primarily
reflected a $1.4 million non-recurring payroll-related charge, offset by a $1.0
million decrease in other spending, primarily incentive compensation expense
and deferred compensation expense. Selling, General, and Administrative Expenses Selling, general, and administrative (SG&A) expenses of $3.9 million in
the second quarter of 2004 were relatively flat compared to the $4.0 million
incurred in the second quarter of 2003. Increases in payroll and other spending
were more than offset by decreases in deferred compensation and incentive
compensation charges. SG&A expenses of $9.3 million in the first half of 2004 were $0.7 million
higher compared to the $8.6 million incurred in the first half of 2003. The
increase primarily reflected higher payroll spending resulting from higher
headcount. 14

Interest Expense Interest expense in the second quarter of 2004 was $0.4 million, and
represented interest on the new $80.5 million, 2% Convertible Subordinated
Notes, which were issued on January 28, 2004. Interest expense in the first
half of 2004 was $2.3 million, and included $1.6 million of interest on the
Senior Secured Notes and certain promissory notes, and $0.7 million of interest
expense on the new Notes. We recorded $3.4 million of interest expense in the second quarter of 2003
and $6.7 million in the first half of 2003. Interest expense primarily
represented interest on the Senior Secured Notes, the Junior Secured Notes, and
certain promissory notes. The Senior Secured Notes and promissory notes were redeemed in full,
including accrued interest, in February 2004. The Junior Secured Notes were
redeemed in full, including accrued interest, in the fourth quarter of 2003.
There were no gains or losses on the redemptions, and there were no
unamortized debt issuance costs. Income Taxes Our wholly-owned thin-film media operation, Komag USA (Malaysia) Sdn.
(KMS), received an eight-year extension of its tax holiday for its first plant
site in Malaysia. The extension provides a tax holiday through June 2011. The
extended tax holiday applies to income generated by sales of disk products
using new technologies. KMS has also been granted additional tax holidays for
its second, third, and fourth plant sites in Malaysia. These tax holidays
expire between December 2006 and 2008. A substantial majority of our income is
generated by sales of disk products covered by these tax holidays. Our estimated annual effective income tax rate for 2004 is 3% and includes
taxes on income generated by sales of product no longer covered under the tax
holiday at our first Malaysian plant site and other tax expenses related to our
U.S. and international operations. Our income tax provisions of $1.0 million and $0.8 million for the first
and second quarters of 2003, respectively, represented foreign withholding
taxes on royalty and interest payments. In the third quarter of 2003, we
received approval from the Malaysian Ministry of Finance for the exemption of
withholding tax on royalty payments made by our Malaysian operations to our
subsidiary in the Netherlands. The exemption is for a period of five years
effective retroactively from January 2002 through December 2006. Therefore, in
the first and second quarters of 2003, we had an accrual for foreign
withholding taxes on royalty and interest payments. We reversed the accrual
and recorded an income tax benefit of $0.8 million in the third quarter of
2003. The withholding taxes are no longer payable. Critical Accounting Policies In the ordinary course of business, we have made a number of estimates and
assumptions relating to the reporting of results of operations and financial
condition in the preparation of our consolidated financial statements in
conformity with accounting principles generally accepted in the United States
of 15

##### Table of Contents



America. Actual results could differ significantly from those estimates if
our assumptions are incorrect. We believe that the following discussion
addresses our most critical accounting policies. These policies are most
important to the portrayal of our financial condition and results and require
managements most difficult, subjective and complex judgments, often as a
result of the need to make estimates about the effect of matters that are
inherently uncertain. Allowance for Sales Returns We estimate our allowance for sales returns based on historical data as
well as current knowledge of product quality. We have not experienced material
differences between our estimated reserves for sales returns and actual
results. It is possible that the failure rate on products sold could be higher
than it has historically been, which could result in significant changes in
future returns. Since estimated sales returns are recorded as a reduction in revenues, any
significant difference between our estimated and actual experience or changes
in our estimate would be reflected in our reported revenues in the period we
determine that difference. There were no significant changes from prior quarter estimates during the
first six months of 2004. Impairment of Long-lived Assets Long-lived assets are evaluated for impairment whenever events or changes
in circumstances indicate that these assets may be impaired or the estimated
useful lives are no longer appropriate. We consider the primary indicators of
impairment to include significant decreases in unit volumes, unit prices or
significant increases in production costs. We review our long-lived assets for
impairment based on estimated future undiscounted cash flows attributable to
the assets. In the event that these cash flows are not expected to be
sufficient to recover the recorded value of the assets, the assets are written
down to their estimated fair values utilizing discounted estimates of future
cash flows. The discount rate used is based on the estimated incremental
borrowing rate at the date of the event that triggers the impairment. There were no impairments of long-lived assets during the first six months
of 2004. Inventory Obsolescence Our policy is to provide for inventory obsolescence based upon an
estimated obsolescence percentage applied to the inventory based on age,
historical trends, and requirements to support forecasted sales. In addition,
and as necessary, we may provide additional charges for future known or
anticipated events. There were no significant changes from prior quarter estimates during the
first six months of 2004. 16

Liquidity and Capital Resources Cash and cash equivalents of $84.6 million at the end of the second
quarter of 2004 increased by $14.6 million from the end of the 2003 fiscal
year. The increase primarily reflected the receipt of $77.4 million and $66.4
million in net proceeds from our January 2004 debt and equity offerings,
respectively, and a $24.4 million increase resulting from consolidated
operating activities, offset by $116.3 million in debt repayments, and $39.2
million of spending on property, plant, and equipment. Consolidated operating activities generated $24.4 million in cash in the
first six months of 2004. The primary components of this change include the
following:  
    
    net income of $26.3 million, plus non-cash charges of $20.4
million;
    
    an accounts receivable increase of $6.4 million primarily
related to the timing of sales, as well as changes in certain
payment terms in 2004;
    
    an inventory increase of $8.6 million, due to the timing of
production and sales of product to certain customers; and
    
    an accrued expenses and other liabilities decrease of $6.8
million, which primarily reflected payments of the 2003 incentive
compensation plan in early 2004. Our total capital spending in the first half of 2004 was $39.2 million,
which included capital expenditures for our capacity expansion as well as the
$10.0 million purchase price for the acquisition of the Trace substrate
facility and equipment. Current non-cancelable capital commitments as of July
4, 2004 totaled $0.4 million. For the remainder of 2004, we plan to spend
approximately $23.0 million on property, plant, and equipment for projects
designed to complete a capacity expansion and improve yield and productivity,
as well as to improve equipment capability for the manufacture of advanced
products. On January 28, 2004, we completed the offering of 4.0 million shares of
our common stock at $20.00 per share, of which selling security holders sold
0.5 million shares, and $80.5 million of 2.0% Convertible Subordinated Notes
(the Notes). The Notes mature on February 1, 2024, bear interest at 2.0%, and require
semiannual interest payments beginning on August 1, 2004. The Notes will be
convertible, under certain circumstances, into shares of the Companys common
stock based on an initial effective conversion price of $26.40. Holders of the
Notes may convert the Notes into shares of the Companys common stock prior to
maturity if: 1) the sale price of the Companys common stock equals or exceeds
$31.68 for at least 20 trading days in any 30 consecutive trading day period
within any fiscal quarter of the Company; 2) the trading price of the Notes
falls below a specified threshold prior to February 19, 2019; 3) the Notes have
been called for redemption; or 4) specified corporate transactions (as
described in the offering prospectus for the notes) occur. The Company may
redeem the Notes on or after February 6, 2007, at specified declining
redemption premiums. Holders of the Notes may require the Company to purchase
the Notes on February 1, 2011, 2014, or 2019, or upon the occurrence of a
fundamental change, at a purchase price equal to 100% of the principal amount
of the Notes, plus accrued and unpaid interest. There are no financial
covenants, guarantees, or collateral associated with the Notes. 17

On February 26, 2004, we used $116.3 million of the $143.8 million in net
proceeds from the offerings to redeem in full the Senior Secured Notes and
certain promissory notes, including accrued interest. We lease our research and administrative facility in San Jose, California
under an operating lease. We also lease, and have sublet, another building in
San Jose. Both of these leases expire in 2007, and have renewal options for
five years. Additionally, we lease certain equipment under operating leases.
These leases expire on various dates through 2008. We have no capital leases. At July 4, 2004, our long-term debt obligations, operating lease

    Unconditional purchase obligations are defined as agreements
to purchase goods or services that are enforceable and legally
binding, and that specify all significant terms, including: fixed or
minimum quantities to be purchased; fixed, minimum, or variable
pricing provisions; and the approximate timing of the transactions.
The amounts are based on our contractual commitments; however, it is
possible we may negotiate lower payments if we choose to exit these
contracts earlier. Based on current operating forecasts, we estimate that the cash balance
and cash from operations will be adequate to support our continuing operations,
capital spending plan, and interest payments for at least the next twelve
months. RISK FACTORS These risks and uncertainties are not the only ones facing our company.
Additional risks and uncertainties that we are unaware of or currently deem
immaterial may also become important factors that may harm our business. If any
of the following risks actually occur, or other unexpected events occur, our
business, financial condition or results of operations could be materially
adversely affected, the value of our stock could decline, and you may lose part
or all of your investment. Further, thisForm 10-Qcontains forward-looking
statements and actual results may differ significantly from the results

Risks Related to Our Business We had a history of operating losses and emerged from chapter 11 bankruptcy in
2002. Despite operating profitability during each of our six most recent
fiscal quarters, we cannot assure you that we will be able to maintain or
improve our profitability in the future. In 2001, after defaulting on our debt obligations, we filed a voluntary
petition for relief under chapter 11 of the United States Bankruptcy Code. We
emerged from chapter 11 bankruptcy in June 2002. Although we have been
profitable in our most recent six quarters, we have a history of losses. Due
to the factors discussed below in this Risk Factors section, including the very
competitive, capital intensive and historically cyclical nature of the disk and
disk drive markets on which our business is dependent, we cannot assure you
that we will be able to sustain or improve our profitability in the future. Downturns in the disk drive manufacturing market and related markets may
decrease our revenues and margins. The market for our products depends on economic conditions affecting the
disk drive manufacturing and related markets, particularly the desktop personal
computer market. We believe that a substantial majority of our finished unit
sales are incorporated into disk drives manufactured by our customers for the
desktop personal computer market. Because of this concentration in a single
market, which we expect to continue, our business is tightly linked to the
success of the personal computer market. The personal computer market has
historically been seasonal and cyclical and has experienced periods of
oversupply and reduced production levels, resulting in significantly reduced
demand for disks and pricing pressures. The effect of these cycles on
suppliers, including disk manufacturers, has been magnified by disk drive
manufacturers practice of ordering components, including disks, in excess of
their needs during periods of rapid growth, thereby increasing the severity of
the drop in the demand for components during periods of reduced growth or
contraction. Accordingly, downturns in the desktop personal computer market may
cause disk drive manufacturers to delay or cancel projects, reduce their
production or reduce or cancel orders for our products. This, in turn, may lead
to longer sales cycles, delays in payment and collection, pricing pressures,
and unused capacity, causing us to realize lower revenues and margins. If our production capacity is underutilized, our gross margin will be adversely
affected and we could sustain significant losses. Our business is characterized by high fixed overhead costs including
expensive plant facilities and production equipment. Our per unit costs and our
gross margin are significantly affected by the number of units we produce and
the amount of our production capacity that we utilize. We are in the process of
increasing our production capacity to approximately 24 million to 25 million
disks per quarter. We are currently operating below this capacity level. If
we are unable to utilize our expanded capacity, we may be unable to increase or
sustain our gross margins. If our capacity utilization decreases for any
reason, including lack of customer demand or cancellation or delay of customer
orders, we could experience significantly higher unit production costs, lower
margins and potentially significant losses. Underutilization
of our production capacity could also result in equipment write-offs,
restructuring charges and employee 19

##### Table of Contents



layoffs. For example, from our 1997 fiscal
year to the third quarter of our 2002 fiscal year, our gross margin was
severely adversely affected by the underutilization of our capacity. If our
production capacity is underutilized for any reason, our financial results and
our business would be severely harmed. We receive a large percentage of our net sales from only a few disk drive
manufacturing customers, the loss of any of which would adversely affect our
sales. Our customers are disk drive manufacturers. A relatively small number of
disk drive manufacturers dominate the disk drive market. According to
TrendFOCUS, four of these manufacturers accounted for 83% of disk drive sales
during the first quarter of 2004. Accordingly, we expect that the success of
our business will continue to depend on a limited number of customers who have
comparatively strong bargaining power in negotiating contracts with us. In the first half of 2004, 48% of our net sales were to Maxtor, 25% were
to HGST, 14% were to Western Digital, and 8% were to Seagate. In fiscal 2003,
38% of our net sales were to Western Digital, 37% were to Maxtor and 17% were
to HGST. If any one of our significant customers reduces its disk requirements
or develops or expands capacity to produce its own disks, and we are unable to
replace these orders with sales to new customers, our sales would be reduced
and our business would suffer. Price competition may force us to lower our prices, causing our gross margin
to suffer. We face significant price competition in the disk industry. High levels of
competition have historically put downward pressure on prices per unit.
Additionally, the average selling price of disks and disk drives rapidly
declines over their commercial life as a result of technological enhancements,
productivity improvements and industry supply increases. We may be forced to
lower our prices or add new products and features at lower prices to remain
competitive, and we may otherwise be unable to introduce new products at higher
prices. We cannot assure you that we will be able to compete successfully in
this kind of price competitive environment. Lower prices would reduce our
ability to generate sales, and our gross margin would suffer. If we fail to
mitigate the effect of these pressures through increased sales volume or
changing our product mix, our net sales and gross margin could be adversely
affected. Price declines are also affected by any imbalances between demand and
supply. For most of 2002, as in the several years prior, disk supply exceeded
demand. As independent suppliers like us struggled to utilize their capacity,
the excess disk supply caused average selling prices for disks to decline.
Pricing pressure on component suppliers was also compounded by high consumer
demand for inexpensive personal computers and consumer devices. In the fourth
quarter of 2002, throughout 2003, and in the first half of 2004, disk prices
were relatively stable, but there is no certainty that this trend will
continue. These supply and demand factors and industry-wide competition could
adjust again and force disk prices down, which, in turn, would put pressure on
our gross margin. 20

Internal disk operations of disk drive manufacturers may adversely affect our
ability to sell our disk products. Disk drive manufacturers such as HGST, Maxtor, and Seagate have large
internal thin-film media manufacturing operations and are able to produce a
substantial percentage of their disk requirements. We compete directly with
these internal operations when we market our products to these disk drive
companies, and indirectly when we sell our disks to customers who must compete
with vertically-integrated disk drive manufacturers. Vertically-integrated
companies have the opportunity to keep their disk-making operations fully
utilized, thus lowering their costs of production. This cost advantage
contributes to the pressure on us and other independent disk manufacturers to
sell disks at lower prices and can severely affect our profitability.
Vertically-integrated companies are also able to achieve a large manufacturing
scale that supports the development resources necessary to advance technology
rapidly. We may not have sufficient resources or manufacturing scale to be able
to compete effectively with these companies as to production costs or
technology development, which would negatively impact our net sales and market
share. If future demand for our products exceeds the production capability of our
existing facilities, we may be required to invest significant capital
expenditures to increase capacity or else risk losing market share. We believe that we have limited capability to further expand our
production capacity using our existing facilities to meet incremental increases
in future demand for our disk products. If demand for our products were to
significantly exceed these capacity levels, we may not be able to satisfy this
increased demand. To increase our production capacity to meet significant
increases in demand for our disks, we would be required to expand our existing
facilities, construct new facilities or acquire entities with additional
production capacities. These alternatives would require significant capital
investments by us and would require us to seek additional equity or debt
financing. There can be no assurance that such financing would be available to
us when needed on acceptable terms, or at all. If we were unable to expand
capacity on a timely basis to meet increases in demand, we could lose market
opportunities for sales and our market share could decline. Further, we cannot
assure you that the increased demand for our disk products would continue for a
sufficient period of time to recoup our capital investments associated with
increasing our production capacity. If we are unable to perform successfully in the highly competitive and
increasingly concentrated disk industry, we may not be able to maintain or gain
additional market share, and our operating results would be harmed. The market for our products is highly competitive, and we expect
competition to continue in the future. Competitors in the thin-film media
industry fall mainly into two groups: Asian-based independent disk
manufacturers and captive disk manufacturers. Our major Asian-based independent
competitors include Fuji Electric, Hoya, Showa Denko and Trace Storage. The
captive disk manufacturers who produce thin-film media internally for their own
use include HGST, Maxtor and Seagate. In late 2002, IBM entered into a joint
venture with Hitachi. The joint venture, named Hitachi Global Storage
Technologies (HGST), 21

##### Table of Contents



includes Hitachis and IBMs disk drive operations and a portion of IBMs
thin-film media operations, and evidences the increasing concentration and
economies of scale in our industry. Many of these competitors have greater
financial resources than we have, which could allow them to adjust to
fluctuating market conditions better than us. Further, they may have greater
technical and manufacturing resources, more extensive name recognition, more
marketing power, a broader array of product lines and preferred vendor status.
To the extent our competitors continue to consolidate and achieve greater
economies of scale, we will face additional competitive challenges. If we are
not able to compete successfully in the future, we would not be able to gain
additional market share for our products, or we may lose our existing market
share, and our operating results could be harmed. Because our products require a lengthy sales cycle with no assurance of high
volume sales, we may expend significant financial and other resources without a
return. With short product life cycles and the rapid technological change
experienced in the disk drive industry, we must frequently qualify new products
with our disk drive manufacturing customers, based on criteria such as quality,
storage capacity, performance, and price. Qualifying disks for incorporation
into new disk drive products requires us to work extensively with our customer
and the customers other suppliers to meet product specifications. Therefore,
customers often require a significant number of product presentations and
demonstrations, as well as substantial interaction with our senior management,
before making a purchasing decision. Accordingly, our products typically have a
lengthy sales cycle, which can range from six to twelve months or longer.
During this time, we may expend substantial financial resources and management
time and effort, while having no assurances that a sale will result, or that
disk drive programs ultimately will result in high-volume production. To the
extent we expend significant resources to qualify products without realizing
sales, our operations will suffer. If our customers cancel orders, our sales could suffer and we are generally not
entitled to receive cancellation penalties to offset the loss of sales revenue. Our sales are generally made pursuant to purchase orders that are subject
to cancellation, modification, or rescheduling without significant penalties.
As a result, if a customer cancels, modifies, or reschedules an order, we may
have already made expenditures that are not recoverable, and our profitability
will suffer. Furthermore, if our current customers do not continue to place
orders with us or if we are unable to obtain orders from new customers, our
sales and operating results will suffer. Because we depend on a limited number of suppliers, if our suppliers experience
capacity constraints or production failures, our production, operating results
and growth potential could be harmed. We rely on a limited number of suppliers for some of the materials and
equipment used in our manufacturing processes, including aluminum blanks,
aluminum substrates, nickel plating solutions, polishing and texturing
supplies, and sputtering target materials. For example, Kobe Steel, Ltd. is our
sole supplier of aluminum blanks, a fundamental component in producing our
disks. We also rely on OMG Fidelity, Inc. and Heraeus Incorporated for supplies
of nickel plating solutions and sputtering target materials, respectively. The
supplier base has been weakened by the poor financial condition of the industry 22

##### Table of Contents



in recent years, and some suppliers have exited the business. Our
production capacity would be limited if one or more of these materials were to
become unavailable or available in reduced quantities, or if we were unable to
find alternative suppliers. For example, due to the significant growth in
demand for our disk products in the fourth quarter of 2002, our sales were
lower during the quarter than the available market opportunity due to our
inability to acquire additional aluminum substrates. If our sources of
materials and supplies were limited or unavailable for a significant period of
time, our production, operating results and ability to grow our business could
be adversely affected. Disk drive program life cycles are short, and disk drive programs are highly
customized. If we fail to respond to our customers demanding requirements, we
will not be able to compete effectively. The disk industry is subject to rapid technological change, and if we are
unable to anticipate and develop products and production technologies on a
timely basis, our competitive position could be harmed. In general, the life
cycles of disk drive programs are short. For example, between approximately
1999 and 2002, areal density rose dramatically on an annual basis.
Additionally, disks must be more customized to each disk drive program. Short
program life cycles and customization have increased the risk of product
obsolescence, and as a result, supply chain management, including just-in-time
delivery, has become a standard industry practice. In order to sustain customer
relationships and sustain profitability, we must be able to develop new
products and technologies in a timely fashion in order to help customers reduce
their time-to-market performance, and continue to maintain operational
excellence that supports high-volume manufacturing ramps and tight inventory
management throughout the supply chain. Accordingly, we have invested and
intend to continue to invest heavily in our research and development program.
If we cannot respond to this rapidly changing environment or fail to meet our
customers demanding product and qualification requirements, we will not be
able to compete effectively. As a result, we would not be able to maximize the
use of our production facilities and our profitability would be negatively
impacted. If we do not keep pace with the rapid technological change in the disk drive
industry, we will not be able to compete effectively, and our operating results
could suffer. Our products primarily serve the 3 1/2-inch disk drive market where
product performance, consistent quality, price and availability are of great
competitive importance. Advances in disk drive technology require continually
lower flying heights and higher areal density. Until recently, areal density
was roughly doubling from year-to-year and even today continues to increase
rapidly, requiring significant improvement in every aspect of disk design.
These advances require substantial on-going process and technology development.
New process technologies, including synthetic anti-ferromagnetic, or SAF and
perpendicular recording media, or PMR, must support cost-effective, high-volume
production of disks that meet these ever-advancing customer requirements for
enhanced magnetic recording performance. We may not be able to develop and
implement these technologies in a timely manner in order to compete effectively
against our competitors products or entirely new data storage technologies. In
addition, we must transfer our technology from our U.S.-based research and
development center to our Malaysian manufacturing operations. If we cannot
advance our process technologies or do not successfully implement those
advanced technologies in our Malaysian operations, or if technologies that we
have chosen not to develop prove to be viable competitive alternatives, we
would not be able to compete effectively. As a result, we 23

would lose market share and face increased price competition from other
manufacturers, and our operating results would suffer. If we fail to improve the quality of, and control contamination in our
manufacturing processes, we will lose our ability to remain competitive. The manufacture of our products requires a tightly-controlled, multi-stage
process, and the use of high-quality materials. Efficient production of our
products requires utilization of advanced manufacturing techniques and clean
room facilities. Disk fabrication occurs in a highly controlled, clean
environment to minimize particles and other yield- and quality-limiting
contaminants. In spite of stringent manufacturing controls, weaknesses in
process control or minute impurities in materials may cause a substantial
percentage of the disks in a lot to be defective. The success of our
manufacturing operations depends, in part, on our ability to maintain process
control and minimize such impurities in order to maximize yield of acceptable
high-quality disks. Minor variations from specifications could have a
disproportionately adverse impact on our manufacturing yields. If we are not
able to continue to improve on our manufacturing processes or maintain
stringent quality controls, or if contamination problems arise, we will not
remain competitive, and our operating results would be harmed. An industry trend towards glass-based applications could negatively impact our
ability to remain competitive. Our finished disks are primarily manufactured from aluminum substrates,
which are the primary substrate used in desktop PC and enterprise applications.
Some disk manufacturers emphasize the use of glass as a basis for the
manufacture of their disks to primarily serve the mobile personal computer
market and certain other consumer applications. These applications are expected
to achieve significant growth in the near future. To the extent glass-based
applications were to achieve significant growth in the market place, we may
lose market share if we were unable to move rapidly to produce glass-based
disks to address the demand. All of our manufacturing operations have been consolidated in Malaysia and our
foreign operations and international sales subject us to additional risks
inherent in doing business on an international level that make it more costly
or difficult to conduct our business. As a result of our consolidation of manufacturing operations in Malaysia,
technology developed at our U.S.-based research and development center must now
be first implemented for high-volume production at our Malaysian facilities
without the benefit of being implemented at a U.S. factory. Therefore, we rely
heavily on electronic communications between our U.S. headquarters and our
Malaysian facilities to transfer specifications and procedures, diagnose
operational issues and meet customer requirements. If our operations in
Malaysia or overseas communications are disrupted for a prolonged period for
any reason, including a failure in electronic communications with our U.S.
operations, the manufacture and shipment of our products would be delayed, and
our results of operations would suffer. Furthermore, our ability to transfer funds from our Malaysian operations
to the United States is 24

##### Table of Contents



subject to Malaysian rules and regulations. In 1999, the Malaysian
government repealed a regulation that restricted the amount of dividends that a
Malaysian company may pay to its stockholders. If not repealed, this regulation
would have potentially limited our ability to transfer funds to the United
States from our Malaysian operations. If similar regulations are enacted in the
future, we may not be able to finance our U.S.-based research and development
and/or repay our U.S. debt obligations as a significant percentage of our
revenues are generated from our Malaysian operations. We are subject to a number of risks of conducting business outside of the
United States. Our sales to customers in Asia, including the foreign
subsidiaries of domestic disk drive companies, account for substantially all of
our net sales. Further, while customers assemble a substantial portion of their
disk drives in Asia, they subsequently sell these products throughout the
world. Therefore, our high concentration of Asian sales does not accurately
reflect the eventual point of consumption of the assembled disk drives. We
anticipate that international sales will continue to represent the majority of
our net sales, and as a result the success of our business is subject to
factors affecting global markets generally. We are subject to these risks to a greater extent than most companies
because, in addition to selling our products outside the United States, our
Malaysian operations account for substantially all of our net sales.
Accordingly, our operating results are subject to the risks inherent with
international operations, including, but not limited to:  
    
    compliance with changing legal and regulatory requirements of foreign jurisdictions;
    
    fluctuations in tariffs or other trade barriers;
    
    foreign currency exchange rate fluctuations, since certain
costs of our foreign manufacturing and marketing operations are
incurred in foreign currency, including purchase of certain
operating supplies and production equipment from Japanese suppliers
in Yen-denominated transactions;
    
    difficulties in staffing and managing foreign operations;
    
    political, social and economic instability;
    
    increased exposure to threats and acts of terrorism;
    
    exposure to taxes in multiple jurisdictions;
    
    local infrastructure problems or failures including but not
limited to loss of power and water supply; and
    
    transportation delays and interruptions. If we are not able to attract and retain key personnel, our operations could be
harmed. Our future success depends on the continued service of our executive
officers, our highly-skilled research, development and engineering team, our
manufacturing team and our key administrative, sales and marketing and support
personnel. Acquiring talented personnel who possess the advanced skills we
require has been difficult. Our bankruptcy filing and our financial performance
in prior years increased the difficulty of attracting and retaining skilled
engineers and other knowledgeable workers. Even though we have emerged from
bankruptcy, we may have difficulty attracting and retaining key personnel. We
may not be able to attract, assimilate or retain highly-qualified personnel to
maintain the capabilities that are 25

##### Table of Contents



necessary to compete effectively. Further, we do not have key person life
insurance on any of our key personnel. If we are unable to retain existing or
hire key personnel, our business, financial condition and operating results
could be harmed. If we do not protect our patents and other intellectual property rights, our
revenues could suffer. It is commonplace to protect technology through patents and other forms of
intellectual property rights in technically sophisticated fields. In the disk
and disk drive industries, companies and individuals have initiated actions
against others in the industry to enforce intellectual property rights.
Although we attempt to protect our intellectual property rights through
patents, copyrights, trade secrets and other measures, we may not be able to
adequately protect our technology. In addition, we may not be able to discover
significant infringements of our technology or successfully enforce our rights
to our technology if we discover infringing uses by others, and such
infringements could have a negative impact on our ability to compete
effectively. Competitors may be able to develop similar technology and also may
have or may develop intellectual property rights and enforce those rights to
prevent us from using such technologies, or demand royalty payments from us in
return for using such technologies. Either of these events may affect our
production, which could materially reduce our revenues and harm our operating
results. We may face intellectual property infringement claims that are costly to
resolve, may divert our managements attention, and may negatively impact our
operations. We have occasionally received, and may receive in the future,
communications from third parties that assert violation of intellectual
property rights alleged to cover certain of our products or manufacturing
processes or equipment. We evaluate on a case-by-case basis whether it would be
necessary to defend against such claims or to seek licenses to the rights
referred to in such communications. In certain cases, we may not be able to
negotiate necessary licenses on commercially reasonable terms, or at all. Also,
if we have to defend such claims, we could incur significant expenses and our
managements attention could be diverted from our core business. Further, we
may not be able to anticipate claims by others that we infringe on their
technology or successfully defend ourselves against such claims. Any litigation
resulting from such claims could have a material adverse effect on our business
and financial results. Historical quarterly results may not accurately predict our performance due to
a number of uncertainties and market factors, and as a result it is difficult
to predict our future results. Our operating results historically have fluctuated significantly on both a
quarterly and annual basis. Additionally, as a result of our emergence from
bankruptcy on June 30, 2002, we are operating our business with a new capital
structure and have been subject to the fresh-start reporting prescribed by
generally accepted accounting principles. Our balance sheet beginning as of
June 30, 2002 reflects the application of these rules. As a result, our
operating results in any quarter may not reflect our future performance,
particularly because our financial condition and results of operations are not
comparable to those in our historical financial statements ended prior to June
30, 2002. We believe that our future operating results will continue to be
subject to quarterly variations based on a wide variety of factors, including: 26

existing business. Acquisitions involve numerous risks, including the
following:  
    
    difficulties in integrating the operations, technologies,
products and personnel of the acquired companies, especially given
the specialized nature of our technology;
    
    diversion of managements attention from normal daily
operations of the business;
    
    potential difficulties in completing projects associated with
in-process research and development;
    
    initial dependence on unfamiliar supply chains or relatively small supply partners; and
    
    the potential loss of key employees of the acquired companies. Acquisitions may also cause us to:  
    
    issue stock that would dilute our current stockholders percentage ownership;
    
    assume liabilities; 27


    
    record goodwill and non-amortizable intangible assets that
will be subject to impairment testing and potential periodic
impairment charges;
    
    incur amortization expenses related to certain intangible assets;
    
    incur large and immediate write-offs; or
    
    become subject to litigation. For example, in 2000, we acquired HMT Technology Corporation (HMT),
another disk manufacturer. As a result of the acquisition of HMT, we acquired
debt liabilities, real property and manufacturing facilities and incurred
significant transaction costs related to the acquisition that raised our
ongoing operational expenses and fixed costs. We were unable to utilize our
increased capacity and generate sufficient revenues to cover the increased
costs and have since sold a majority of all unused facilities. Mergers and acquisitions of high-technology companies are inherently
risky, and no assurance can be given that any future acquisitions by us will be
successful and will not materially adversely affect our business, operating
results or financial condition. The failure to manage and successfully
integrate acquisitions we make could harm our business and operating results in
a material way. Even if an acquired company has already developed and marketed
products, there can be no assurance that product enhancements will be made in a
timely fashion or that pre-acquisition due diligence will have identified all
possible issues that might arise with respect to products or the integration of
the company into our company. The nature of our operations makes us susceptible to material environmental
liabilities, which could result in significant compliance and clean-up expenses
and adversely affect our financial condition. We are subject to a variety of federal, state, local, and foreign
regulations relating to:  
    
    the use, storage, discharge, and disposal of hazardous
materials used during our manufacturing process;
    
    the treatment of water used in our manufacturing process; and
    
    air quality management. We are required to obtain necessary permits for expanding our facilities.
We must also comply with new regulations on our existing operations, which may
result in significant costs. Public attention has increasingly been focused on
the environmental impact of manufacturing operations that use hazardous
materials. If we fail to comply with environmental regulations or fail to
obtain the necessary permits:  
    
    we could be subject to significant penalties;
    
    our ability to expand or operate in California or Malaysia could be restricted;
    
    our ability to establish additional operations in other locations could be restricted; or
    
    we could be required to obtain costly equipment or incur
significant expenses to comply with environmental regulations. 28

Furthermore, our manufacturing processes rely on the use of hazardous
materials and any accidental hazardous discharge could result in significant
liability and clean-up expenses, which could harm our business, financial
condition, and results of operations. Earthquakes or other natural or man-made disasters could disrupt our
operations. Our U.S. facilities are located in San Jose, California. In addition, Kobe
and other Japanese suppliers of our key manufacturing supplies and sputtering
machines are located in areas with seismic activity. Our Malaysian operations
have been subject to temporary production interruptions due to localized
flooding, disruptions in the delivery of electrical power, and, on one occasion
in 1997, by smoke generated by large, widespread fires in Indonesia. If any
natural or man-made disasters do occur, operations could be disrupted for
prolonged periods, and our business would suffer. Anti-takeover provisions in our certificate of incorporation could discourage
potential acquisition proposals or delay or prevent a change of control. We have protective provisions in place designed to provide our board of
directors with time to consider whether a hostile takeover is in our best
interests and that of our stockholders. Our certificate of incorporation
provides that we have three classes of directors. As a result, a person could
not take control of the board until the third annual meeting after the closing
of the takeover, since a majority of our directors will not stand for election
until that third annual meeting. This provision could discourage potential
acquisition proposals and could delay or prevent a change in control of the
company and also could diminish the opportunities for a holder of our common
stock to participate in tender offers, including offers at a price above the
then-current market price for our common stock. These provisions also may
inhibit fluctuations in our stock price that could result from takeover
attempts. Risks Related to our Indebtedness We are leveraged, and our debt service requirements will continue to make us
vulnerable to economic downturns. We recently completed a public common stock offering of 4.0 million shares
(of which 0.5 million were sold by selling stockholders) and a public $80.5
million Convertible Subordinated Notes offering. We used a significant portion
of the proceeds of the offerings to redeem all of our outstanding Senior Notes.
Even though we redeemed all of the outstanding Senior Notes using the proceeds
of the common stock offering and the debt offering, we now have debt service
obligations under the Convertible Subordinated Notes. As a result, we may be
required to use a substantial portion of our cash flow from operations to meet
our obligations on our Convertible Subordinated Notes, thereby reducing the
availability of cash flow to fund our business. Debt service obligations
arising from the offering of our Convertible Subordinated Notes could limit our
flexibility in planning for or reacting to changes in our industry, and could
limit our ability to borrow more money for operations and implement our
business strategy in the future. In addition, our leverage may restrict our
ability to obtain additional financing in the future. We will continue to be
more leveraged than some of our competitors, which may place us at a
competitive disadvantage because our 29

interest and debt repayment requirements makes us more susceptible to
downturns in our business. Our holding company structure makes us dependent on cash flow from our
subsidiaries to meet our obligations. Most of our operations are conducted through, and most of our assets are
held by, our subsidiaries. Therefore, we are dependent on the cash flow of our
subsidiaries to meet our debt obligations. Our subsidiaries are separate legal
entities that have no obligation to pay any amounts due under the Convertible
Subordinated Notes, or to make any funds available therefore, whether by
dividends, loans or other payments. Our subsidiaries have not guaranteed the
payment of the Convertible Subordinated Notes, and payments on the Convertible
Subordinated Notes are required to be made only by us. Except to the extent we
may ourselves be a creditor with recognized claims against our subsidiaries,
subject to any limitations contained in our debt agreements, all claims of
creditors and holders of preferred stock, if any, of our subsidiaries will have
priority with respect to the assets of such subsidiaries over the claims of our
creditors, including holders of the Convertible Subordinated Notes. The assets of our subsidiaries may not be available to make payments on our
debt obligations. We may not have direct access to the assets of our subsidiaries unless
these assets are transferred by dividend or otherwise to us. The ability of our
subsidiaries to pay dividends or otherwise transfer assets to us is subject to
various restrictions, including restrictions under other agreements to which we
are a party under applicable law. 
 ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK We are exposed to foreign currency exchange rate risk. We currently do not
use derivative financial instruments to hedge such risk. The primary objective of our investment activities is to preserve
principal while at the same time maximizing yields without significantly
increasing risk. We invest primarily in high-quality, short-term debt
instruments. A substantial majority of our revenue, expense, and capital purchasing
activities are transacted in U.S. dollars. However, a large portion of our
payroll, certain operating expenses, and capital purchases are transacted in
other currencies, primarily Malaysian ringgit. Since late 1998, the ringgit
has been pegged at a conversion rate of 3.8 Malaysian ringgit to the U.S.
dollar. If the pegging is lifted in the future, we will evaluate whether or not
we will enter any hedging contracts for the Malaysian ringgit. Expenses
recorded in Malaysian ringgit in the first six months of 2004 totaled
approximately $26.1 million. We have $80.5 million in convertible subordinated notes outstanding.
These notes bear interest at 2% and mature in February 2024. A hypothetical 100
basis point increase in interest rates would result in approximately $0.8
million of additional interest expense each year. 30

Officer and our Chief Financial Officer have designed and evaluated our
disclosure controls and procedures, or caused such disclosure controls and
procedures to be designed under their supervision, pursuant to Rules 13a  15

disclosure controls and procedures are effective to ensure that the information
required to be disclosed in our filings under periodic Securities and Exchange
Commission filings is gathered, analyzed, and disclosed with adequate
timeliness, accuracy, and completeness, based on an evaluation of such controls
