KOMAG, INCORPORATED
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(UNAUDITED)
MARCH 30, 2003

Note 1. Basis of Presentation

The accompanying unaudited 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 consolidated financial position, operating results, and
cash flows for the periods presented, have been included. Operating results for
the three months ended March 30, 2003, are not necessarily indicative of the
results that may be expected for the year ending December 28, 2003.

Komag, Incorporated (KUS) filed a voluntary petition for reorganization
under chapter 11 of the United States Bankruptcy Code on August 24, 2001 (the
Petition Date). The petition was filed with the United States Bankruptcy Court
for the Northern District of California. The petition related only to the
Companys U.S. corporate parent, KUS, and did not include any of its
subsidiaries.

KUS proposed, and in May 2002 the Bankruptcy Court confirmed, the Further
Modified First Amended Plan of Reorganization (the Plan), which became
effective on June 30, 2002. KUS emerged from bankruptcy on that date. In
accordance with Statement of Position 90-7 (SOP 90-7), Financial Reporting by
Entities in Reorganization Under the Bankruptcy Code, issued by the American
Institute of Certified Public Accountants, the Company adopted fresh-start
reporting and reflected the effects of the adoption in the consolidated
financial statements for the six months ended June 30, 2002. Fresh-start
reporting requires the recording of assets and liabilities at fair value, and
stockholders equity based on the reorganization (enterprise) value. As a
result of the adoption of fresh-start reporting, the consolidated statements of
operations and statements of cash flows for periods ended after June 30, 2002
are prepared on a basis of accounting that is different from that utilized for
periods ended prior to June 30, 2002. Therefore, the Companys consolidated
statements of operations and cash flows for the three months ended March 30,
2003 are not comparable to the consolidated statements of operations and cash
flows for the three months ended March 31, 2002.

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. The three-month reporting periods included in
this report consisted of 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):

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.

In accordance with Financial Accounting Standards Board (FASB) Statement
of Financial Accounting Standards (SFAS) No. 123, Accounting for Stock-Based
Compensation, and SFAS No. 148, Accounting for Stock-Based Compensation 
Transition and Disclosure  an Amendment of FASB Statement No. 123, the Company
provides pro forma disclosure of the effect on net income and earnings per
share had the fair value method, as prescribed by SFAS No. 123, been used.

The following table reflects the effect on net income and earnings per
share of the Company after emergence from bankruptcy (the Successor Company)
for the three months ended March 30, 2003, and on the net loss of the Company
prior to emergence from bankruptcy (the Predecessor Company) for the three
months ended March 31, 2002, had the fair value method been applied to all
outstanding and unvested awards.

Upon emergence from chapter 11 on June 30, 2002, the Company had a
significant change in the structure of stockholders equity. Accordingly,
earnings per share of the Predecessor Company are not presented, as the amounts
are not meaningful.

For purposes of the pro forma disclosure, the fair value of each option
and stock purchase right grant is estimated on the date of grant using the
Black-Scholes option pricing model. The following assumptions were used for
grants in the first three months of 2003 (there were no grants in the first
three months of 2002): a risk-free interest rate of 2.68%, a volatility factor
of the expected market price of the Companys common stock of 87.1%, and a
weighted-average expected life of the options of four years. There was no
dividend yield included in the calculation, as the Company does not pay
dividends. The weighted average fair value of options granted during the first
three months of 2003 was $4.32.

For purposes of the pro forma disclosure, the fair value of the employees
purchase rights under the 2002 Employee Stock Purchase Plan (ESPP) has been
estimated using the Black-Scholes model assuming a risk-free interest rate of
1.18% for the first three months of 2003 (there was no ESPP Plan in effect in
2002). The volatility factor of the expected market price was 62.2% for the
first three months of 2003. The weighted-average expected life of the purchase
rights was six months. The weighted-average fair value of those purchase
rights granted in the first three months of 2003 was $1.77.

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 earnings 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 earnings per share by application of the treasury stock
method.

Upon emergence from chapter 11 on June 30, 2002, the Company had a
significant change in the structure of stockholders equity. Accordingly,
earnings per share of the Predecessor Company are not presented, as the amounts
are not meaningful.

The following table sets forth the computation of net income per share (in
thousands, except per share amounts):

##### Table of Contents



Incremental common shares attributable to outstanding common stock options
(assuming proceeds would be used to purchase treasury stock) of 114,640 for the
three months ended March 30, 2003 were not included in the diluted net income
per share calculation because the effect would have been anti-dilutive.

Incremental common shares attributable to outstanding common stock
warrants (assuming proceeds would be used to purchase treasury stock) of
1,000,000 for the three months ended March 30, 2003 were not included in the
diluted net income per share calculation because the effect would have been
anti-dilutive.

Recent Accounting Pronouncements:In November 2002, the FASB issued
Interpretation No. 45, Guarantors Accounting and Disclosure Requirements for
Guarantees, Including Indirect Guarantees of Indebtedness of Others (FIN 45).
FIN 45 requires a guarantor to (i) include disclosure of certain obligations
and (ii) if applicable, at the inception of the guarantee, recognize a
liability for the fair value of other certain obligations undertaken in issuing
a guarantee. The disclosure provisions of FIN 45 are effective for financial
statements of interim or annual reports that end after December 15, 2002. The
adoption of the disclosure provision had no impact on the Companys
disclosures. The recognition and measurement provisions of FIN 45 are
effective for guarantees issued or modified after December 29, 2002. The
Company adopted the recognition and measurement provisions of FIN 45 in the
first quarter of 2003, and the adoption had no impact on the Companys
consolidated financial statements.

In January 2003, the FASB issued Interpretation No. 46, Consolidation of
Variable Interest Entities (FIN 46). This interpretation of Accounting Research
Bulletin No. 51, Consolidated Financial Statements, addresses consolidation by
business enterprises of variable interest entities. Under current practice, two
enterprises generally have been included in consolidated financial statements
because one enterprise controls the other through voting interests. FIN 46
defines the concept of variable interests and requires existing
unconsolidated variable interest entities to be consolidated by their primary
beneficiaries if the entities do not effectively disperse risks among the
parties involved. This interpretation applies immediately to variable interest
entities created after January 31, 2003. It applies in the first fiscal year or
interim period beginning after June 15, 2003, to variable interest entities in
which an enterprise holds a variable interest that it acquired before February
1, 2003. If it is reasonably possible that an enterprise will consolidate or
disclose information about a variable interest entity when FIN 46 becomes
effective, the enterprise shall disclose information about those entities in
all financial statements issued after January 31, 2003. The interpretation may
be applied prospectively with a cumulative-effect adjustment as of the date on
which it is first applied or by restating previously issued financial
statements for one or more years with a cumulative-effect adjustment as of the
beginning of the first year restated. The Company adopted FIN 46 on the first
day of its 2003 fiscal year. The adoption had no impact on the Companys
consolidated financial statements.

Note 2. Related Parties and Major Customers

Prior to June 30, 2002, sales to Western Digital Corporation (Western
Digital) were reported as related party transactions, as Western Digital owned
more than 5% of the Companys outstanding common stock. For the periods
subsequent to June 30, 2002, Western Digital was no longer a related party, as
it
9Table of Contents

owned less than 5% of the companys outstanding stock. Sales to Western
Digital in the first quarter of 2002 were $41.0 million.

In the first quarter of 2003, sales to Western Digital and Maxtor
Corporation (Maxtor) accounted for 48% and 35%, respectively, of the Companys
revenue. Sales to Hitachi Global Storage Technologies and IBM combined
accounted for 16% of the Companys revenue in the first quarter of 2003. In
the first quarter of 2002, sales to Western Digital, Maxtor, and Seagate
Technology (Seagate) accounted for 67%, 23%, and 8%, respectively, of the
Companys revenue.

Note 3. Interest Expense

In the first quarter of 2003, the Company recorded $3.4 million in
interest expense, which primarily represented interest on the Companys debt
issued on emergence from chapter 11. No interest expense was recorded in the
first quarter of 2002, as interest expense was suspended while the Company was
in chapter 11.

Note 4. Reorganization Costs, Net

No reorganization expenses were recorded in the first quarter of 2003,
compared to $1.0 million in the first quarter of 2002. Reorganization expenses
in the first quarter of 2002 primarily reflected professional fees related to
the chapter 11 bankruptcy proceeding.

Note 5. Income Taxes

The Companys income tax provisions of $1.0 million and $0.4 million for
the three-month periods ended March 30, 2003, and March 31, 2002,
respectively, represent foreign withholding taxes on royalty and interest
payments.

The Companys wholly-owned thin-film media operation, KMS, received a
five-year extension of its initial tax holiday for its first plant site. The
tax holiday is effective through June 2003. KMS has also been granted
additional tax holidays for its second and third plant sites in Malaysia.
These tax holidays are effective through December 2006 and 2008, respectively.
The Company has applied for an extension of the tax holiday expiring in June
2003. The Company may or may not receive an extension.

Due to the uncertainty as to the timing and amount of future income, the
Company continues to provide a full valuation allowance against its deferred
tax assets.

Note 6. Minority Interest/Equity Interest in Net Loss of Related Companies

The minority interest for Kobe USAs 20% share of KMTs net income in the
first quarter of 2002 was less than $0.1 million. KMT ceased operations in
the third quarter of 2002.

In the first quarter of 2002, the Company recorded a $1.5 million loss as
its equity share in the net
10Table of Contents

loss of Chahaya, a former equity investment. Chahaya ceased operations
in the fourth quarter of 2002. The Company currently has no minority or equity
interests in related companies.

Note 7. Goodwill and Other Intangible Assets

In June 2001, the FASB issued SFAS No. 142, Goodwill and Other Intangible
Assets, which requires that goodwill should not be amortized, but should be
subject to an impairment test at least annually.

The Company completed a transitional impairment analysis of its goodwill
during the six months ended June 30, 2002 and recorded a transitional
impairment loss of $47.5 million as of the first day of fiscal 2002. The
transitional impairment loss of $47.5 million was recognized as the cumulative
effect of a change in accounting principle in the Companys consolidated
statement of operations.

Upon the adoption of fresh-start reporting as of June 30, 2002, the
Company recorded goodwill of $33.9 million, which equaled the reorganization
value in excess of amounts allocable to identifiable net assets recorded in
accordance with SOP 90-7. In the fourth quarter of 2002, the Company performed
its first annual goodwill impairment analysis under SFAS No. 142, utilizing the
market capitalization method required for single-business-unit companies.
Because the Companys market capitalization was significantly less than net
book value at December 29, 2002, the Company wrote off the entire $33.9 million
goodwill balance in the fourth quarter of 2002.

Upon the adoption of fresh-start reporting as of June 30, 2002, the
Company recorded other intangible assets in the amount of $17.6 million. As of
March 30, 2003, other intangible assets included; 1) developed technology of
$3.1 million (less accumulated amortization of $0.7 million), which is being
amortized on a straight-line basis over its estimated useful life of three and
one-half years; 2) a volume purchase agreement of $7.7 million (less
accumulated amortization of $2.1 million), which is being amortized on a
straight-line basis over its useful life of two and three-quarter years; and 3)
patent costs of $0.3 million (less accumulated amortization of zero).
Amortization of intangible assets in the first quarter of 2003 was $0.9
million, which was included in cost of sales. Amortization of intangible
assets in the first quarter of 2002 was $3.1 million, which was included in
operating expenses.

of 2003.

Note 9. Subsequent Events

In April 2003, the Companys Board of Directors approved an amendment to
the 2002 Qualified Stock Plan (2002 Stock Plan) to accelerate the date on which
the additional 750,000 shares will be reserved under the 2002 Stock Plan, and
to increase the total number of shares to be reserved for issuance by only
450,000 shares, a 300,000 share decrease from the aforementioned 750,000 share
increase that was originally approved by stockholders in October 2002.

In April 2003, the Companys Board of Directors approved an amendment to
the 2002 Employee Stock Purchase Plan to increase the total number of shares
subject to purchase under the Plan by 300,000 shares so that a total of 600,000
shares will be available for purchase. The Board proposes that the 300,000
shares to be used for this increase come from the reduction to the 2002 Stock
Plan increase as noted above.

These amendments are subject to stockholder vote and approval at the
annual meeting of stockholders on May 20, 2003.

Results of Operations

Overview

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
would deteriorate rapidly if the disk market were to worsen.

Adverse conditions in the thin-film media market, which began in mid-1997,
impacted our business through the majority of 2002. Demand for disk drives grew
rapidly during the mid-1990s, and industry forecasts were for continued strong
growth. Along with many of our competitors (both independent disk manufacturers
and captive disk manufacturers owned by vertically integrated disk drive
companies), in 1996 we committed to expansion programs and substantially
increased media manufacturing capacity in 1997. In 1997, the rate of growth in
demand for disk drives fell. Disk drive manufacturers abruptly reduced their
orders for media from independent suppliers and relied more heavily on internal
capacity to supply a larger proportion of their media requirements. The media
industrys capacity expansion, coupled with the decrease in the rate of demand
growth, resulted in excess media
13Table of Contents

production capacity. Due to classic micro-economic forces, this excess
industry capacity caused sharp declines in average selling prices for disk
products as independent suppliers struggled to utilize their capacity.

In addition, by the end of 1998, most disk drives manufactured were
transitioned to the use of advanced magneto-resistive media and recording
heads. This transition led to unprecedented increases in areal density and,
therefore, the amount of data that could be stored on a single disk platter.
Increased storage capacity per disk allows drive manufacturers to offer
lower-priced disk drives by incorporating fewer components into their disk
drives. Because of this lower disk-per-drive ratio, demand for disks decreased
overall during the period from 1997 through the majority of 2002, resulting in
substantial excess disk production capacity. The significant amount of captive
capacity employed by certain disk drive manufacturers also continues to impair
the market opportunities for independent disk suppliers such as our company.

As a result of the continuing excess disk production capacity in our
industry, we closed U.S. manufacturing operations, merged with HMT Technology
Corporation, and consolidated our combined U.S.-based manufacturing operations
in Malaysia over the three-year period from 1999 through 2001. In June 2002, we
announced that we would close the KMT research and development facility in
Santa Rosa, California. The closure was completed in the third quarter of 2002.

With the relocation of our manufacturing operations to our Malaysian
facilities, our San Jose, California site is focused solely on activities
related to research, process development, and product prototyping. Our selling,
general, and administrative functions also remain in California. The shift of
high-volume production to our cost-advantaged Malaysian manufacturing plants
has improved our overall cost structure, resulting in lower unit production
costs, and has improved our ability to respond to the continuing price
pressures in the disk industry. We expect to maintain low costs by fully
utilizing our Malaysian operations. In addition, we may acquire other low cost
operations and enter into long-term contracts with suppliers to reduce or
stabilize costs and grow our business.

As discussed in Note 1, we emerged from chapter 11 bankruptcy on June 30,
2002. In accordance with SOP 90-7, we adopted fresh-start reporting and
reflected the effects of the adoption in the consolidated financial statements
for the six months ended June 30, 2002. Fresh-start reporting requires the
recording of assets and liabilities at fair value, and stockholders equity
based on reorganization (enterprise) value. Because our consolidated statement
of operations for the three months ended March 30, 2003, was prepared on a
different basis of accounting (in accordance with fresh-start reporting
requirements), it is not comparable to our consolidated statement of operations
for the three months ended March 31, 2002.

Net Sales

Consolidated net sales increased by 72% to $105.5 million in the first
quarter of 2003, from $61.4 million in the first quarter of 2002.

The overall increase reflected an increase in finished unit sales volume
to 16.7 million units in the

14

##### Table of Contents



first quarter of 2003 from 9.5 million units in the first quarter of 2002.
The volume increase was somewhat offset by a decline in the finished unit
average selling price, from $5.87 in the first quarter of 2002 to $5.57 in the
first quarter of 2003. We believe that the unit shipment increase primarily
reflected market share gains, which began in the second half of 2002, and which
resulted from our early qualification on new advanced programs at our
customers. The finished unit average selling price decline was primarily
related to our efforts to increase market share, as well as continued general
customer pricing pressure.

Other disk sales in the first quarter of 2003 were $12.4 million, compared
to $5.6 million in the first quarter of 2002. The increase reflected higher
sales of textured aluminum substrates and single-sided disks in the first
quarter of 2003 than in the first quarter of 2002. Other disk sales in the
first quarter of 2002 primarily comprised sales of polished aluminum substrates
and single-sided disks.

In the second quarter of 2003, we expect relatively flat shipment volume
and revenue, continued downward pricing pressure, and higher volume shipments
of our advanced disk products than in the first quarter of 2003.

In the first quarter of 2003, sales to Western Digital and Maxtor
accounted for 48% and 35%, respectively, of our revenue. Sales to Hitachi
Global Storage Technologies and IBM combined accounted for 16% of our revenues
in the first quarter of 2003. In the first quarter of 2002, sales to Western
Digital, Maxtor, and Seagate accounted for 67%, 23%, and 8%, respectively, of
our revenue.

We expect to continue to derive a substantial portion of our sales from
Western Digital and Maxtor, and from a small number of other customers.
Historically, our sales have been concentrated among several significant
customers, and we expect it to remain concentrated. However, our customer sales
distribution may vary from quarter to quarter based on the qualifications of
our disks in specific customers drive programs and the success of those
programs in the disk drive marketplace. As a result of the April 1999
acquisition of Western Digitals media operation and the related volume
purchase agreement, we expect our sales to remain highly concentrated with
Western Digital. The volume purchase agreement expires in April 2005.

Sales of 60GB per platter disks and greater increased to 45% of net sales
in the first quarter of 2003, compared to less than 1% in the same period of
2002. The increase was the result of the continued rapid customer evolution to
higher storage densities. There was also a decrease in lower GB disks, from
99% in the first quarter of 2002 to 55% in the first quarter of 2003. We
anticipate sales of 60/80GB per-platter disks to increase for the rest of 2003.

Gross Margin

Our overall gross margin percentage for the first quarter of 2003 was
21.6%, an 11.5 point increase compared to a gross margin percentage of 10.1%
for the first quarter of 2002. The economies of scale associated with higher
sales and production volume significantly lowered our fixed cost per disk, and
accounted for 16.3 points of the increase. However, lower costs per disk from
the higher sales and production volumes were somewhat offset by the decline in
the finished unit average selling price, which

15

##### Table of Contents



accounted for a 4.8 point decrease in the gross margin percentage.

We expect to maintain our variable cost per unit at levels similar to the
last three quarters while continuing to advance our technology. We expect our
fixed cost per unit in the remainder of 2003 to vary based on changes in
production volumes from the level achieved in the first three months of 2003.

Research, Development, and Engineering Expenses

Research, development, and engineering expenses of $9.9 million in the
first quarter of 2003 were $0.5 million higher compared to the $9.4 million in
the first quarter of 2002. The increase primarily reflected deferred
stock-based compensation expense of $0.3 million, and a net $0.2 million
increase in other spending. There was no deferred compensation expense in
the first quarter of 2002.

We expect research, development, and engineering spending in the second
quarter of 2003 to be similar to the first quarter of 2003.

Selling, General, and Administrative Expenses

Selling, general, and administrative expenses of $4.6 million in the first
quarter of 2003 were $0.4 million higher compared to the $4.2 million incurred
in the first quarter of 2002. The increase primarily reflected deferred
stock-based compensation expense of $0.4 million. There was no deferred
compensation expense in the first quarter of 2002.

We expect selling, general, and administrative spending in the second
quarter of 2003 to be similar to spending in the first quarter of 2003.

Amortization of Intangible Assets

In the first quarter of 2003, we recorded $0.7 million of amortization on
the volume purchase agreement with Western Digital, and $0.2 million of
developed technology amortization. These amounts were included in cost of
sales. See Note 3.

Amortization of intangible assets in the first quarter of 2002 was $3.1
million, which was included in operating expenses. This amount included the
remaining amortization of $2.6 million under the original Western Digital
volume purchase agreement, which ended in the first quarter of 2002.

Interest Income and Interest Expense

Interest income was $0.1 million in the first quarter of 2003 and the
first quarter of 2002.

Total cash and cash equivalents were $36.3 million at the end of the first
quarter of 2003, and $24.0 million at the end of the first quarter of 2002.

16

##### Table of Contents



In the first quarter of 2003, we recorded $3.4 million in interest
expense, which primarily represented interest on our debt issued on emergence
from chapter 11. No interest expense was recorded in the first quarter of 2002,
as interest expense was suspended while we were in chapter 11.

We expect interest expense in the second quarter of 2003 to be similar to
the first quarter of 2003.

Other Income, Net

Other income, net in the first quarter of 2003 was $1.1 million, and
primarily reflected a $0.7 million gain on the sale of certain idle
manufacturing equipment and other assets, and a $0.3 million property tax
refund. Other income, net was $3.0 million in the first quarter of 2002, and
primarily reflected a $2.4 million gain on the sale of certain idle
manufacturing equipment.

Reorganization Costs, Net

No reorganization costs were recorded in the first quarter of 2003,
compared to $1.0 million in the first quarter of 2002. The 2002 charges
primarily reflected professional fees related to the chapter 11 bankruptcy
proceeding. We do not anticipate incurring any reorganization costs in 2003.

Income Taxes

Our income tax provisions of $1.0 million and $0.4 million for the
three-month periods ended March 30, 2003, and March 31, 2002, respectively,
represent foreign withholding taxes on royalty and interest payments.

Our wholly-owned thin-film media operation, KMS, received a five-year
extension of its initial tax holiday for its first plant site. The tax holiday
is effective through June 2003. KMS has also been granted additional tax
holidays for its second and third plant sites in Malaysia. These tax holidays
are effective through December 2006 and 2008, respectively. We have applied
for an extension of the tax holiday expiring in June 2003. We may or may not
receive an extension.

Due to the uncertainty as to the timing and amount of future income, we
continue to provide a full valuation allowance against our deferred tax assets.

Minority Interest/Equity Interest in Net Loss of Related Companies

The minority interest for Kobe USAs 20% share of KMTs net income in the
first quarter of 2002 was less than $0.1 million. KMT ceased operations in
the third quarter of 2002.

In the first quarter of 2002, the Company recorded a $1.5 million loss as
its equity share in the net loss of Chahaya, a former equity investment.
Chahaya ceased operations in the fourth quarter of 2002. The Company currently
has no minority or equity interests in related companies.

Cumulative Effect of Change in Accounting Principle

We adopted SFAS No. 142 and recorded the effects of adoption in June 2002
on a cumulative effect basis as of the first day of the 2002 fiscal year.

In accordance with SFAS No. 142, we were required to perform a
transitional impairment analysis of our goodwill. The transitional impairment
loss of $47.5 million was recognized in the first quarter of 2002 as the
cumulative effect of a change in accounting principle in our consolidated
statement of operations.

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 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. Historically, we have not
experienced material differences between our estimated reserves for sales
returns and actual results. However, 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.

From December 29, 2002 to March 30, 2003, our allowance for sales returns
increased by $0.3 million, and reflects an increase in estimated sales returns.

Long-lived Assets

Long-lived assets are generally evaluated for impairment on an individual
acquisition, market, or product basis 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. Periodically, 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
18Table of Contents

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. Land and buildings held for sale are evaluated for
impairment periodically when there are significant changes in market conditions
for commercial real estate, and carried at amounts based on independent
valuation less estimated selling costs.

Liquidity and Capital Resources

Cash and cash equivalents of $36.3 million at the end of the first quarter
of 2003 increased by $12.8 million from the end of the 2002 fiscal year. The
increase primarily reflected a $16.5 million increase resulting from
consolidated operating activities, offset by $4.0 million of spending on the
acquisition of property, plant, and equipment.

Consolidated operating activities generated $16.5 million in cash in the
first quarter of 2003. The primary components of this change include the
following:



| |  |  | net income of $5.1 million, net of non-cash depreciation of
$10.6 million, $1.6 million of non-cash interest expense, non-cash
amortization of $0.9 million, and deferred stock-based compensation
expense of $0.8 million, less a $0.7 million gain on asset disposals;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| |  |  | an accounts receivable increase of $2.1 million primarily due
to increased sales in the last month of the quarter;                                                                                                                                                      
|
| |  |  | a prepaid expense decrease of $1.9 million primarily due to insurance premium amortization;                                                                                                                                                                             
|
| |  |  | an accounts payable decrease of $1.0 million due to more timely payments; and                                                                                                                                                                                           
|
| |  |  | an accrued expenses and other liabilities decrease of $0.8
million, which primarily reflected payments of previously accrued
expenses related to restructurings.                                                                                                        

In the first quarter of 2003, we spent $4.0 million on fixed asset
acquisitions to improve our Malaysian plant manufacturing capabilities, and
received $0.7 million in proceeds on the sale of idle manufacturing equipment.
Sales of idle manufacturing equipment may vary from quarter to quarter. We
also repaid $0.2 million of debt.

Current non-cancelable capital commitments as of March 30, 2003 totaled
$6.8 million. For the remainder of 2003, we plan to spend approximately $16.0
million on property, plant, and equipment for projects designed to improve
yield and productivity, as well as to improve equipment capability for the
manufacture of advanced products.

We lease and sublease research and administrative facilities under
operating leases that expire at various dates between 2004 and 2007. Certain of
these leases include renewal options for five years. We have no capital leases.

We have available liquidity through a revolving credit facility (the Exit
Facility) we entered into on June 30, 2002 simultaneously with our emergence
from bankruptcy, that allows for advances of up to $15.0 million at any time
outstanding, with a $3.0 million letter of credit sub-facility. The Exit
Facility expires June 30, 2005. As of March 30, 2003, there were no borrowings
under the Exit Facility. Our total outstanding borrowings under the Exit
Facility at any one time may not exceed the lesser of $15.0 million or 70% of
the fair market value of certain of our assets less a reserve, and less
additional reserves that may be created by the Administrative Agent from time
to time, as set forth in the Exit Facility agreement. The Exit Facility is
secured by a first-priority security interest in substantially all of our
assets, including tangible and intangible assets (except in the case of our
ownership interest in its foreign subsidiaries, which is limited to a pledge of
65% of such equity interests). Interest is payable monthly in arrears at a rate
of 12% per annum on the outstanding principal amount. We paid a commitment fee
of $0.3 million to obtain the Exit Facility, and we pay ongoing unused
commitment fees due on a monthly basis at an annual rate of 0.5% on the average
unused portion of the $15.0 million facility during the preceding month. These
unused commitment fees have been, and we expect them to be, approximately
$6,250 a month.

The Exit Facility contains affirmative, negative and financial covenants
binding on us and our subsidiaries. The negative covenants include restrictions
on our ability to incur indebtedness and make guarantees, grant liens,
sell assets, declare dividends, make investments, and make capital
expenditures. Financial covenants include the maintenance of minimum adjusted
tangible net worth, minimum adjusted working capital and a total cash debt
service coverage ratio.

In accordance with our confirmed Plan, in addition to the $15.0 million
Exit Facility (discussed above), we issued $85.3 million of cash pay notes and
$43.5 million of paid-in-kind (PIK) notes (Senior Secured Notes), $7.0 million
of subordinated PIK notes (Junior Secured Notes), and $1.7 million of secured
and unsecured promissory notes.

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 and debt payments for at least the next
twelve months. Additionally, we can borrow under the Exit Facility, which is
described above. We currently have no borrowings under the Exit Facility.

RISK FACTORS

Investing in our securities involves a high degree of risk. You should
carefully consider the risks and uncertainties described below when considering
whether or not to invest in our company. 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, 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.

RISKS RELATED TO OUR FINANCIAL POSITION AND OUR COMMON STOCK

We recently emerged from a chapter 11 bankruptcy reorganization and have a
history of losses.

We sought protection under chapter 11 of the United States Bankruptcy Code
in August 2001. We incurred net losses of approximately $68.1 million and
$296.4 million during the fiscal years ended December 31, 2000, and December
30, 2001, respectively. For the nine-month period ended September 29, 2002, we
incurred a $50.9 million loss before a gain of $396.4 million for
extinguishment of liabilities subject to compromise and revaluation of assets
and liabilities for fresh-start reporting, and before a cumulative change in
accounting principle loss of $47.5 million. For the fourth quarter ended
December 29, 2002, we recorded a net loss of $27.5 million after a $33.9
million non-cash goodwill impairment charge. We were profitable in the first
quarter of 2003, reporting $5.1 million of net income. This was our first
profitable quarter (excluding one-time credits) since the fourth quarter of
1997. See Managements Discussion and Analysis of Financial Condition and
Results of Operations. While our shipments and revenues have increased in
the last two quarters, and we achieved profitability in the first quarter of
2003, we cannot assure you that we will sustain current shipment levels, grow,
or maintain profitability.

We continue to be leveraged and our debt service requirements make us more
vulnerable to economic downturn in the technology markets we serve and in the
economy generally.

Even after our emergence from bankruptcy, our long-term debt and
short-term debt was approximately $141.6 million as of March 30, 2003. While we
believe that our cash balance and future operating cash flow, together with our
financing arrangements, will be sufficient to finance our operating
requirements, our indebtedness restricts our ability to obtain additional
financing in the future and, because we may be more leveraged than some of our
competitors, may place us at a competitive disadvantage. Also, the Exit
Facility (a revolving credit facility of up to $15.0 million), Senior Notes
Indenture, and Junior Notes Indenture that we entered into as part of our
emergence from bankruptcy contain covenants that impose operating and financial
restrictions on us. These covenants could adversely affect our ability to
finance future operations, potential acquisitions or capital needs or to engage
in other business activities that may be in our interest. In addition, if we
cannot achieve the financial results necessary to maintain compliance with
these covenants, we could be declared in default and be required to sell or
liquidate our assets to repay outstanding debt.

Our historical financial information is not comparable to our current financial
condition and results of operations, making it difficult to analyze our
financial prospects.

As a result of our emergence from bankruptcy on June 30, 2002, we are
operating our business with a new capital structure. We were also subject to
the fresh-start reporting prescribed by generally accepted accounting
principles, and our balance sheet as of March 30, 2003 reflects the application
of these rules. Accordingly, our financial condition and results of operations
are not comparable to the financial condition and results of operations
reflected in our historical financial statements ended prior to June 30, 2002,
making it difficult to assess our future prospects based on historical
performance.

We have significant stockholders who own a large percentage of our common stock
and could substantially influence all matters requiring stockholder approval.

We have several significant stockholders who, in the aggregate, own
approximately 74% of our common stock, and together are able to significantly
influence all matters requiring approval by our stockholders, including new
financings, the election of directors and the approval of mergers or other
business combinations. To the extent that the interests of these stockholders
are different than those of other stockholders, important company decisions may
not reflect the interests of all stockholders.

Sales of stock by significant stockholders holders may negatively affect the
market price.

We have several significant stockholders who, in the aggregate, own
approximately 74% of our common stock, and who are not restricted as to the
prices at which they may sell the stock. Shares sold below the current level at
which the shares of our common stock are trading may adversely affect the
market price of our common stock. This large amount of stock, if sold all at
once or in blocks, could have a negative effect on the market price of our
common stock.

We expect to experience volatility in our stock price, which could negatively
affect your investment.

An investment in our common stock involves substantial risks. The stock
market generally, and the market for stocks of companies with lower market
capitalizations, like us, in particular, have from time to time experienced and
likely will again experience significant price and volume fluctuations that are
unrelated to the operating performance of a particular company.

We are currently listed on the Nasdaq National Market System, and if we are
unable to meet the listing requirements, we may have our stock delisted and our
stock would be negatively affected.

In February 2003, we were approved to re-list our stock on the Nasdaq
National Stock Market. On February 25, 2003, our stock ceased trading on the
OTC Bulletin Board and began trading on the Nasdaq National Stock Market under
the symbol KOMG.

We may not be able to continue to meet the applicable listing requirements
such as maintaining certain trading price thresholds. As a result, our stock
may be delisted. If our stock is not traded through a

market system, it may not be liquid, and we may be unable to obtain future
equity financing, or use our common stock as consideration for mergers or other
business combinations.

The Senior Secured Notes are subordinated to the Exit Facility. The Junior
Secured Notes are, in turn, subordinated to the Senior Secured Notes. In the
event of a dissolution, equity holders would be unlikely to receive
distributions.

We currently have no balance outstanding under the Exit Facility, but we
can choose to make a draw under the Exit Facility at any time so long as the
conditions precedent are satisfied. The Senior Secured Notes are subordinated
in right of payment to the Exit Facility, and the Junior Secured Note are, in
turn, subordinated in right of payment to the Senior Secured Notes. As a result
of such subordination, in the event of an acceleration declared because of (1)
our liquidation or insolvency, (2) a payment default, (3) a covenant default,
or (4) the occurrence of other events of default, our assets will be available
to pay obligations on the Senior Secured Notes only after the Exit Facility is
paid in full and on the Junior Secured Notes only after the Senior Secured
Notes have been paid in full. There may not be sufficient assets remaining to
pay amounts due on any or all of the Senior Secured Notes or the Junior Secured
Notes then outstanding. In the event of liquidation or insolvency, holders of
equity securities would receive a distribution only after payment in full to
each of the Exit Facility, the Senior Secured Notes, and the Junior Secured
Notes. It is likely there would be nothing left to distribute to equity
holders at such time.

If there is not an active market for our notes, the trading price and liquidity
of the notes could be materially adversely affected.

We cannot assure you that any market for our notes will develop more fully
or, if it does develop more fully, that it will be maintained. If an active
market for the notes fails to be maintained or sustained, the trading price and
liquidity of the notes could be materially adversely affected.

Since emerging from bankruptcy, we have not paid any dividends on our common
stock and do not anticipate doing so in the foreseeable future.

We currently anticipate that all of our earnings, if any, will be retained
for repayment of our outstanding debt and for development and expansion of our
business. We do not anticipate paying any cash dividends on our common stock in
the foreseeable future. In addition, the Exit Facility contains covenants that
restrict payment of cash dividends.

RISKS RELATED TO OUR BUSINESS

Demand for disk drives is largely tied to demand for personal computers and
fluctuations in and reduced demand for personal computers may result in
cancellations or reductions in demand for our product.

Trend Focus, a data-gathering and data-publishing company, estimates that
75% of the disks consumed during 2002 were incorporated into disk drives for
the desktop personal computer market.

##### Table of Contents



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. Historically, demand for personal computers has been seasonal
and cyclical. Trend Focus also forecasts a 7% growth in PC demand in 2003. Due
to the high fixed costs of our business, fluctuations in demand resulting from
this seasonality and cyclicality can lead to disproportionate changes in the
results of our operations. If cancellations or reductions in demand for our
products occur in the future, our business, financial condition, and results of
operations could be seriously harmed.

Delays and cancellations of our customer orders may cause us to under-utilize
our production capacity, which could significantly reduce our gross margins and
result in significant losses.

Our business is characterized by high fixed costs. If there is a decrease
in demand for our products, our production capacity could be underutilized,
and, as a result, we may experience:



| |  |  | equipment write-offs;                           
| | - |  | ------------------------------------------------
|
| |  |  | restructuring charges;                          
|
| |  |  | operating losses;                               
|
| |  |  | reduced average selling prices for our products;
|
| |  |  | increased unit costs; and                       
|
| |  |  | employee layoffs.                               

The occurrence of one or more of the above would negatively impact our
gross margins.

There is a high concentration of customers in the disk drive market, and we
receive a large percentage of our revenues from only a few customers, the loss
of any of which would adversely affect our sales.

Our customers are disk drive manufacturers. Given the relatively small
number of disk drive manufacturers, we expect that we will continue to depend
on a limited number of customers. This high customer concentration is due to
the following factors:



| |  |  | the high-volume requirements of the dominant disk drive
manufacturers;                                                                                                                                                                                                                    
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| |  |  | a tendency to rely on a few suppliers because of the close
interrelationship between media performance and disk drive
performance;                                                                                                                                                        
|
| |  |  | the complexity of integrating components from a variety of
suppliers; and                                                                                                                                                                                                                 
|
| |  |  | the increases in storage densities that have led to decreases
in the platter count per drive. With lower platter counts, disk
drive manufacturers with captive disk manufacturing operations have
excess capacity and they rely less on independent sources of media,
such as our company.

In the first quarter of 2003, 48% of our net sales were to Western Digital
and 35% were to Maxtor. During fiscal 2002, 61% of our net sales were to
Western Digital and 30% were to Maxtor. During fiscal 2001, 59% of our net
sales were to Western Digital and 27% were to Maxtor. If any one of our
significant customers reduce their media requirements or develop or expand
capacity to produce thin-film disks for

25

##### Table of Contents



internal use, our sales will be reduced and, as a result, our business,
financial condition and operating results could suffer.

If we are unable to perform successfully in the highly competitive and
increasingly concentrated thin-film media industry, we may not be able to gain
additional market share or we may lose our existing 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 disk
industry fall mainly into two groups: Asian-based manufacturers and captive
manufacturers. Our Asian-based competitors include Fuji Electric, Trace
Storage, Showa Denko, and Hoya. Showa Denko and Mitsubishi Chemical
Corporation agreed to combine operations in 2002. The U.S. captive
manufacturers include the disk media operations of Seagate Technology, IBM and
Maxtor. In late 2002, IBM entered into a joint venture with Hitachi. The joint
venture, named Hitachi Global Storage Technology, includes Hitachis and IBMs
disk drive operations and a portion of IBMs disk 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. 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.

The imbalance between demand and supply has further intensified
competition in the industry. For most of 2002, as in the last several years,
media supply exceeded media demand. As independent suppliers like us struggled
to utilize their capacity, the excess media supply caused average selling
prices for disk products to decline. Pricing pressure on component suppliers
has also been compounded by high consumer demand for inexpensive personal
computers and consumer devices. In the fourth quarter of 2002 and the first
quarter of 2003, media supply and demand began to come into balance, there were
some shortages of disks, and disk prices began to stabilize, but there is no
certainty that this will continue. We expect supply and demand factors and
industry-wide competition to continue to put pressure on our profit margin.

Price competition may force us to lower our prices and our revenues and gross
margins will suffer.

We face fierce price competition in the disk media industry. Continued
high levels of competition have continued to put downward pressure on prices
per unit. Additionally, the average selling price of disk drives rapidly
declines over its commercial life as a result of technological enhancements,
productivity improvements, and industry supply increases. We may be forced to
continue 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 revenue, and our gross margin would suffer. If
we fail to mitigate the effect of these pressures through reducing the cost of
our products or changing our product mix, our revenues and gross margins could
be adversely affected.

We have historically made and, in the future, expect to continue to make
acquisitions, and acquisitions could disrupt our operations and harm our
operating results.

The continuing growth of our business is dependent on; 1) market growth;
2) our ability to develop and introduce, on a timely basis, new products to
our customers; and 3) our ability to manufacture continuously, in high volume,
high-quality advanced products to meet our customers needs. Additionally,
achieving low product cost through careful monitoring of yield, materials, and
operating supplies consumed, and achieving high-volume production in our
low-cost manufacturing locations is critical to our ability to maintain
profitability. Through acquisitions of other companies and technologies, we may
be able to address the need to develop new products, enhance our ability to
achieve low product costs, and facilitate increased units sales and/or revenue
growth. Acquisitions involve numerous risks, including the following:



| |  |  | difficulties in integrating the operations, technologies,
products and personnel of the acquired companies;                                                  
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| |  |  | diversion of managements attention from normal daily
operations of the business;                                                                            
|
| |  |  | potential difficulties in completing projects associated with
in-process research and development;                                                           
|
| |  |  | difficulties in entering markets in which we have no or
limited direct prior experience and where competitors in such
markets have stronger market positions;
|
| |  |  | initial dependence on unfamiliar supply chains or relatively small supply partners;                                                                          
|
| |  |  | insufficient revenues to offset increased expenses associated with acquisitions; and                                                                         
|
| |  |  | the potential loss of key employees of the acquired companies.                                                                                               

Acquisitions may also cause us to:



| |  |  | issue common stock that would dilute our current stockholders percentage ownership;                                                       
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------
|
| |  |  | assume liabilities;                                                                                                                        
|
| |  |  | 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.                                                                                                              

Mergers and acquisitions of high-technology companies are inherently
risky, and no assurance can be given that our future acquisitions 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 all pre-acquisition due diligence will have identified
all possible issues that might arise with respect to such products.

If we are not able to fund our business with cash generated by operations or
raise future capital, we may be forced to reduce or suspend operations.

The disk media business has historically been capital-intensive, and we
believe that in order to remain competitive, we will likely continue to have to
make investments for capital expenditures, working capital, and research and
development. If we cannot generate sufficient cash flows from operations, or
raise additional funds required by our business to remain competitive, we may
be forced to reduce or suspend operations.

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 rapid technological change, we must
frequently qualify new products, based on criteria such as quality, storage
capacity, performance, and price. We must also be able to achieve rapidly
high-volume production and sales. Hard disk drive programs have increasingly
become bimodal in that a few programs are high-volume and the remaining
programs are relatively small in terms of volume. Supply and demand balance can
change quickly from customer to customer and from program to program.

Further, qualifying thin-film disks for incorporation into new disk drive
products requires us to work extensively with the 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. 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 our share of the program
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, they may not be required to pay any penalties,
and our sales could suffer.

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.

Our customers internal disk operations may limit our ability to sell our
product.

Disk drive manufacturers such as Seagate, IBM, Maxtor, and Hitachi Global
Storage Technology have large internal media manufacturing operations. In 2002,
Seagate, IBM, and Hitachi internally produced more than 89% of their media
requirements, and Maxtor internally produced approximately 45%

28

##### Table of Contents



of its media 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 ability 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 media manufacturers to sell disks at
prices so low that historically we have been unprofitable, and we cannot be
sure we can maintain profitability. Vertically-integrated companies are also
able to achieve a large scale that supports the development resources necessary
to advance technology rapidly. We may not have sufficient resources to be able
to compete effectively with these companies. If we are unable to absorb
development costs through scale, and because of continued downward price
pressures, our business, financial condition, and operations could suffer.

Because we depend on a limited number of suppliers, if our suppliers experience
capacity constraints or production failures, our production and operating
results 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 substrates,
nickel plating solutions, polishing and texturing supplies, and sputtering
target materials. For instance, Kobe Steel, Ltd. is our primary supplier of
aluminum substrates, a fundamental component in producing our disks. The
supplier base has been further weakened by the poor financial condition of the
industry, 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. If our sources of materials and supplies were unavailable for a
significant period of time, our production and operating results could be
adversely affected. Due to the significant growth in demand for our disk
products in the fourth quarter of 2002, our sales were actually somewhat
constrained due to the need to acquire substrates from sources other than our
traditional internal and external suppliers.

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.

Our industry has experienced rapid technological change, and if we are
unable to anticipate and develop, on a timely basis, products and production
technologies, our competitive position could be harmed. In general, the life
cycles of recent disk drive programs have been shortening. For example, since
1999, the industry has doubled storage density annually compared to a slower
pace in prior years. Additionally, media 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 achieve profitability, we must be
able to develop new products and technologies in a timely fashion that can 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. 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 minimize our

29

inventory losses, and our profitability would be negatively impacted.

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. Downturns in these markets may
cause disk drive manufacturers to delay or cancel projects, reduce their
production or reduce or cancel orders for our products. In the event of such a
downturn, customers may experience financial difficulty, cease operations or
fail to budget for the purchase of our products. This, in turn, may lead to
longer sales cycles, delays in payment and collection, and price pressures,
causing us to realize lower revenues and margins. In particular, many of our
customers and potential customers have experienced declines in their revenues
and operations. In addition, recent war in Iraq and the terrorist acts of
September 11, 2001, as well as subsequent terrorist activities and threats,
have created an uncertain economic environment. We cannot predict the impact of
these economic uncertainties, or of any related military action on our
customers or business, particularly in light of the fact that we rely heavily
on overseas production and sales. We believe that, in light of these
uncertainties, some businesses may curtail or eliminate spending on technology
related to our products.

If we do not keep pace with rapid technological change, we will not be able to
compete effectively, and our operating results would suffer.

Our thin-film disk products primarily serve the 3 1/2-inch hard disk drive
market, where product performance, consistent quality, price, and availability
are of great competitive importance. To succeed in an industry characterized by
rapid technological developments, we must continuously advance our thin-film
technology at a pace consistent with, or faster than, our competitors.

Advances in hard disk drive technology demand continually lower glide
heights and higher storage densities. Over the last several years, storage
density has roughly doubled each year, requiring significant improvement in
every aspect of disk design. These advances require substantial on-going
process and technology development. New process technologies must support
cost-effective, high-volume production of thin-film disks that meet these
ever-advancing customer requirements for enhanced magnetic recording
performance. We may not be able to develop and implement such technologies in a
timely manner in order to compete effectively against our competitors products
and/or entirely new data storage technologies. In addition, we must transfer
our technology from our U.S. 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 would lose our market share and face increased price
competition from other manufacturers, and our operating results would suffer.

We must continue to improve the quality of, and control contamination in, our
manufacturing processes in order to be competitive.

The manufacture of our high-performance, thin-film disks 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.

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 unique skills we
require has been difficult. Our bankruptcy filing and our recent historical
financial performance have increased the difficulty of attracting and retaining
skilled engineers and other knowledgeable workers. We expect that it will
continue to be difficult to attract and retain key personnel, even though we
have emerged from bankruptcy. We may not be able to attract, assimilate, or
retain highly-qualified personnel to maintain the capabilities that are
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 will suffer.

It is commonplace to protect technology through patents and other forms of
intellectual property rights in technically sophisticated fields. In the disk
drive industry, it is common for companies and individuals to initiate 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
protect adequately 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 would 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 rights
alleged to cover certain of our products or manufacturing processes or
equipment. We evaluate whether it would be necessary to defend against the
claims or to seek licenses to the rights referred to in such communications. In
those cases, we may not be able to negotiate necessary licenses on commercially
reasonable terms, or at all. Also, if we have to defend those claims, we could
incur significant expenses and our managements attention could be diverted
from our other business. Further, we may not be able to anticipate claims by
others that we infringe 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 future performance,
which is subject to fluctuation due to many uncertainties.

Our operating results historically have fluctuated significantly on both a
quarterly and annual basis. As a result, our operating results in any quarter
may not reflect our future performance. We believe that our future operating
results will continue to be subject to quarterly variations based on a wide
variety of factors, including:



| |  |  | timing of significant orders, order cancellations,                                                                                                                                  
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| |  |  | changes in our product mix and average selling prices;                                                                                                                              
|
| |  |  | modified, adjusted or rescheduled shipments;                                                                                                                                        
|
| |  |  | availability of media versus demand for media;                                                                                                                                      
|
| |  |  | the cyclical nature of the hard disk drive industry;                                                                                                                                
|
| |  |  | our ability to develop and implement new manufacturing process technologies;                                                                                                        
|
| |  |  | increases in our production and engineering costs associated
with initial design and production of new product programs;                                                            
|
| |  |  | the extensibility of our process equipment to meet more
stringent future product requirements;                                                                                      
|
| |  |  | our ability to introduce new products that achieve
cost-effective high-volume production in a timely manner, timing of
product announcements, and market acceptance of new products;
|
| |  |  | the availability of our production capacity, and the extent
to which we can use that capacity;                                                                                      
|
| |  |  | changes in our manufacturing efficiencies, in particular
product yields and input costs for direct materials, operating
supplies and other running costs;                           
|
| |  |  | prolonged disruptions of operations at any of our facilities for any reason;                                                                                                        
|
| |  |  | changes in the cost of or limitations on availability of labor; and                                                                                                                 
|
| |  |  | structural changes within the disk media industry, including
combinations, failures, and joint venture arrangements.                                                                

We cannot forecast with certainty the impact of these and other factors on
our revenues and operating results in any future period. Our expense levels are
based, in part, on expectations as to future revenues. If our revenue levels
are below expectations, our operating results are likely to suffer. Because

thin-film disk manufacturing requires a high level of fixed costs, our
gross margins are extremely sensitive to changes in volume. At constant average
selling prices, reductions in our manufacturing efficiency cause declines in
our gross margins. Additionally, decreasing market demand for our products
generally results in reduced average selling prices and/or low capacity
utilization that, in turn, adversely affect our gross margins and operating
results. Further, because we were required to implement fresh-start reporting
when we emerged from chapter 11 proceedings, our historical information prior
to June 30, 2002 is significantly less meaningful as a predictor of future
performance.

Because we depend on our Malaysian operations, we are exposed to unavoidable
risks in transmitting technology from U.S. facilities to Malaysian facilities.
These risks could adversely impact our results of operations.

During the third quarter of 1999, we announced that all media production
would be consolidated into our Malaysian factories. In the fourth quarter of
2000, we decided to end the manufacture of aluminum substrates in Santa Rosa,
California. Currently, aluminum substrates are primarily manufactured by a
Malaysian vendor. In addition, we ended production of polished disks in our
Eugene, Oregon, facility in the second quarter of 2001, which we acquired as
part of our merger with HMT Technology Corporation in October 2000. All
polished disks are manufactured by our Malaysian factories. Further, in the
second quarter of 2001, we transferred the manufacturing capacity of HMTs
Fremont, California, facility to Malaysia, and closed all of our U.S. media
manufacturing operations, leaving us fully dependent on our Malaysian
manufacturing operations.

Technology developed at our U.S. research and development center must now
be first implemented 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. facilities and Malaysia 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.

If we do not receive an extension on our tax holiday for a plant site in
Malaysia, we could become subject to significantly higher tax liabilities and
tax expense than we have experienced in the past, and our operating results
would suffer.

Our wholly-owned thin-film media operation, Komag USA (Malaysia) SDN
(KMS), has a ten-year initial tax holiday that expires in June 2003, for its
first plant site in Malaysia. The Malaysian government is considering extending
this tax holiday but there can be no assurances that it will. If we do not
receive an extension, we would become subject to income tax expense for that
location. Therefore, we may incur significantly higher income tax liabilities
and tax expense than we have experienced in the past. Significantly higher
income tax liabilities and tax expense would negatively affect our operating
results.

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.

We are subject to a number of risks of conducting business outside of the
U.S. Our sales to customers in Asia, including the foreign subsidiaries of
domestic disk drive companies, account for substantially all of our net sales
from our U.S. and Malaysian facilities. 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.

We are subject to these risks to a greater extent than most companies
because, in addition to selling our products outside the U.S., our Malaysian
operations account for substantially all of our 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;                                                                                                                                                                                                                                                
|
| |  |  | 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.                                                                                                                                                                                                                                                   

In addition, our ability to transfer funds from our Malaysian operations
to the U.S. is 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 U.S. 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.

Given our reliance on manufacturing facilities and suppliers in Asia, the
outbreak of SARS may negatively impact our operating results.

The recent outbreak of severe acute respiratory syndrome (SARS) that began
in China, Hong Kong, Singapore, and Vietnam could have a negative impact on our
operations. Our normal operating processes could be hindered by a number of
SARS-related factors, including, but not limited to:

|
| |  |  | reduced travel between ourselves, customers, and suppliers.                                        

If the number of cases continues to rise or spread to other areas, our
sales and operating results could be harmed.

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.

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.

We rely on a continuous power supply to conduct our business, and an energy
crisis in California could disrupt our operations and increase our expenses.

From time to time in the past, California has experienced energy
shortages. An energy crisis could disrupt our research and development
activities and increase our expenses. In the event of an acute power shortage,
which occurs when power reserves for the State of California fall below 1.5%,
California has, on occasion, implemented, and may in the future continue to
implement, rolling blackouts throughout the state. We currently do not have
back-up generators or alternate sources of power in the event of a blackout,

and our insurance does not provide coverage for any damages we or our
customers may suffer as a result of any interruption in our power supply. If
blackouts interrupt our power supply, we would be temporarily unable to
continue operations at our California-based facilities. This could damage our
reputation, harm our ability to retain existing customers and to obtain new
customers, and could result in lost revenue, any of which could substantially
harm our business and results of operations.

Furthermore, the regulatory changes affecting the energy industry
instituted in 1996 by the California government have caused power prices to
increase. Under the revised regulatory scheme, utilities were encouraged to
sell their plants, which had traditionally produced most of Californias power,
to independent energy companies that were expected to compete aggressively on
price. Instead, due in part to a shortage of supply, wholesale prices increased
dramatically over the past year. If wholesale prices continue to increase, our
operating expenses will likely increase, as our headquarters and certain
facilities are in California.

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 merger, 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.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to financial market risks, including foreign currency
exchange rates. We currently do not use derivative financial instruments to
hedge such risks.

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 three months of 2003 totaled approximately $13.5
million.

We have $85.3 million in senior secured cash pay notes outstanding which
bear interest at the prime rate plus 3% (such rate not to be less than 8% per
annum) and mature in June 2007. A hypothetical 100 basis point increase in
interest rates would result in approximately $0.9 million of additional
interest expense each year.




ITEM 4. CONTROLS AND PROCEDURES

We maintain a rigorous set of disclosure controls and procedures and
internal controls designed to ensure that information required to be disclosed
in our filings under the Securities Exchange Act of 1934 is recorded,
processed, summarized, and reported within the time periods specified in the
Securities and Exchange Commissions rules and forms. Our principal executive
and financial officers, including our Chief Executive Officer and our Chief
Financial Officer, have evaluated our disclosure controls and procedures
pursuant to Rule 13a-14 of the Securities Exchange Act of 1934 within 90 days
of the filing of this Quarterly Report on Form 10-Q, and have determined that
such disclosure controls and procedures are effective in timely alerting them
to material information relating to our company which is required to be
disclosed in our filings under periodic Securities and Exchange Commission
filings.

Subsequent to our evaluation, there were no significant changes in
internal controls or other factors that could significantly affect our internal
controls, including any corrective actions with regard to significant
deficiencies and material weaknesses.
