                       HUTCHINSON TECHNOLOGY INCORPORATED
        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - UNAUDITED


Unless otherwise indicated, references to "2001" mean HTI's fiscal year ending
September 30, 2001 and references to "2000" mean HTI's fiscal year ended
September 24, 2000.

(1)  ACCOUNTING POLICIES

The condensed consolidated financial statements have been prepared by the
Company, without audit, pursuant to the rules and regulations of the Securities
and Exchange Commission. The information furnished in the condensed consolidated
financial statements include normal recurring adjustments and reflect all
adjustments which are, in the opinion of management, necessary for a fair
presentation of such financial statements. Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with accounting principles generally accepted in the United States have been
condensed or omitted pursuant to such rules and regulations. Although the
Company believes that the disclosures are adequate to make the information
presented not misleading, it is suggested that these condensed consolidated
financial statements be read in conjunction with the financial statements and
the notes thereto included in the Company's latest Annual Report on Form 10-K.
The quarterly results are not necessarily indicative of the actual results that
may occur for the entire fiscal year.

(2)   ACCOUNTING PRONOUNCEMENTS

The Company adopted Statement of Financial Accounting Standards No. 133,
"Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133"), as
amended by Statement of Financial Accounting Standards No. 138, "Accounting for
Certain Derivative Instruments and Certain Hedging Activities - an Amendment of
FASB Statement No. 133" ("SFAS 138"), effective September 25, 2000. SFAS 133
requires a company to recognize all derivatives on the balance sheet at fair
value. Derivatives that are not hedges must be adjusted to fair value through
income. If the derivative is a hedge, depending on the nature of the hedge,
changes in the fair value of the hedged assets, liabilities or firm commitments
are recognized through earnings or in other comprehensive income until the
hedged item is recognized in earnings. The ineffective portion of a derivative's
change in fair value will be immediately recognized in earnings. The Company has
determined that the effect of adopting SFAS 133 and SFAS 138 was not material to
the earnings and the financial position of the Company.

(3)  ASSET IMPAIRMENT AND OTHER

The Company recorded charges in its first quarter of 2000 of $43,528,000 for
impaired assets and $3,000,000 for severance costs. These charges are reflected
on the accompanying statement of operations as "Asset impairment and other."

Advances in technology have enabled disk drive manufacturers to reduce their
costs by using fewer components, including suspension assemblies, in each disk
drive. Industry forecasts during quarter one of 2000 indicating further
decreases in component counts, extending from the desktop market to server
drives, triggered an impairment review by the Company late in that quarter. As a
result, the Company prepared an analysis, in accordance with Statement of
Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed Of", to determine if
there was impairment of certain excess manufacturing equipment and tooling,
primarily for TSA suspensions. The analysis resulted in an impairment charge
based on the difference between the carrying value and the estimated fair value
of these assets. Fair value was based on discounting estimated future cash flows
for assets grouped at the lowest level for which there were identifiable cash
flows at a discount rate commensurate with the risks involved.

During quarter one of 2000, the Company terminated approximately 250 employees
in its workforce, including indirect positions in its administrative,
development and manufacturing support areas at all plant sites. The workforce
reduction resulted in a charge for severance costs of $3,000,000. The full
amount of these severance costs has been paid.

(4)  BUSINESS AND CUSTOMERS

The Company is the world's leading supplier of suspension assemblies for hard
disk drives. Suspension assemblies hold the recording heads in position above
the spinning magnetic disks in the drive and are critical to maintaining the
necessary microscopic clearance between the head and disk. The Company developed
its leadership position in suspension assemblies through research, development
and design activities coupled with a substantial investment in manufacturing
technologies and equipment. The Company is focused on continuing to develop
suspension assemblies which address the rapidly changing requirements of the
hard disk drive industry. The Company also is evaluating other product
opportunities in the medical device and other markets, but does not expect to
generate significant revenue during 2001. A breakdown of customer sales is as
follows:

(6)  NET LOSS PER SHARE

Basic loss per share is computed by dividing net loss available for common
shareholders by the weighted average number of common shares outstanding during
the year. Diluted loss per share is computed under the treasury stock method and
is calculated to compute the dilutive effect of potential common shares. A
reconciliation of these amounts is as follows (dollars in thousands):

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. At March 25, 2001, the
Company had unused tax credits and net operating loss carryforwards of
$77,841,000, of which $5,525,000 can be carried forward indefinitely and
$72,316,000 expire at various dates through 2020. A valuation allowance of
$55,120,000 has been recognized to offset the related deferred tax assets due to
the uncertainty of realizing the benefit of certain tax credits and net
operating loss carryforwards.

(9)  LEGAL CONTINGENCIES

On September 18, 2000, HTI commenced a lawsuit in the United States District
Court for the District of Minnesota against the Magnecomp Group, an
unincorporated association of companies, and seven members of the Magnecomp
Group. The lawsuit alleges that the Magnecomp Group has sold infringing products
without a license, and alleges infringement of nine of HTI's patents related to
the design and manufacture of suspension assemblies. The lawsuit requests
damages, including treble damages, attorneys' fees, costs, and an injunction
against the Magnecomp Group.

On October 12, 2000, Magnecomp Corporation commenced a lawsuit in the United
States District Court for the Central District of California against HTI. The
lawsuit alleges that HTI has sold products infringing four patents, engaged in
anti-competitive conduct in violation of federal and state antitrust laws, and
violated California state law regarding contractual interference and unfair
competition. The lawsuit requests damages, including treble damages, attorneys'
fees, costs, punitive damages, and an injunction against HTI. On December 8,
2000, the California District Court issued an order granting HTI's motion to
transfer the California action to the United States District Court for the
District of Minnesota.

The two lawsuits described above have been consolidated for pre-trial purposes,
and both currently are in the discovery phase.

The Company and certain users of the Company's products have from time to time
received, and may in the future receive, communications from third parties
asserting patents against the Company or its customers which may relate to
certain of the Company's manufacturing equipment or products or to products that
include the Company's products as a component. The Company is currently a party
to the litigation described above. In addition, certain of its customers have
been sued on patents having claims closely related to products sold by the
Company. If any third party makes a valid infringement claim and a license were
not available on terms acceptable to the Company, the Company's operating
results could be adversely affected. The Company expects that, as the number of
patents issued continues to increase, and as the Company grows, the volume of
intellectual property claims could increase. The Company may need to engage in
litigation to enforce patents issued or licensed to it, protect trade secrets or
know-how owned by it or determine the enforceability, scope and validity of the
intellectual property rights of others. The Company could incur substantial
costs in such litigation or other similar legal actions, which could have a
material adverse effect on its results of operations.

The Company is a party to certain other claims arising in the ordinary course of
business. In the opinion of management, the outcome of such claims will not
materially affect the Company's current or future financial position or results
of operations.

GENERAL

Since the late 1980's, we have derived virtually all of our revenue from the
sale of suspension assemblies to a small number of customers. We currently sell
a variety of suspension assemblies based on several standard designs. Suspension
assemblies are a critical component of hard disk drives and our results of
operations are highly dependent on the hard disk drive industry. The hard disk
drive industry is intensely competitive and volatile and our results of
operations have been adversely affected from time to time due to hard disk drive
industry slowdowns, technological changes that impact industry component demand,
production yields and our own product transitions.

Improvements in data density of hard disk drives, which have outpaced storage
capacity requirements, have enabled disk drive manufacturers to reduce their
costs by using fewer components, including suspensions, in each drive. Improved
head-gimbal assembly yields at our customers and shifts in our share of certain
drive programs have also, to a lesser extent, decreased demand for our products
since the third quarter of 1999. In the second quarter of 2001, lingering
effects of slower holiday season sales of personal computers, concerns about a
weak economy, and previous overbuying by businesses, resulted in lower drive
demand. This led to our unit shipments for the second quarter of 2001 declining
significantly from first quarter levels. For the third quarter of 2001, we
expect our unit shipments to be relatively flat to down somewhat from the second
quarter of 2001. Given these market conditions, we continue to have limited
visibility for future demand. We will continue to have excess capacity until
some combination of the following events occurs: average component counts within
disk drives stabilize or increase, or overall disk drive demand growth increases
significantly, or our share of certain drive programs increases, or
Internet-related storage growth increases, or new applications for disk storage
become more widespread.

Our selling prices are subject to pricing pressure from our customers and market
pressure from our competitors. Our selling prices also are affected by changes
in overall demand for our products, changes in the specific products our
customers buy and a product's life cycle. A typical life cycle for our products
begins with higher pricing when a product is introduced, decreasing prices when
it is mature, and slightly increasing pricing as it is phased out. To offset
price decreases during a product's life, we rely primarily on higher sales
volume and improving our manufacturing yield to reduce the cost of manufacturing
our mature products. If we cannot reduce our manufacturing costs as prices
decline during a product's life cycle, or at all, our business, financial
condition and results of operations could be materially adversely affected.

Our gross margins have fluctuated and will continue to fluctuate based upon a
variety of factors such as changes in demand, product mix, selling prices, the
level of utilization of our production capacity, increases in production and
engineering costs associated with production of new products, manufacturing
yields and changes in the cost of materials. Gross margins have been negatively
impacted in each quarter since the third quarter of 1999 by lower than expected
suspension shipments resulting in excess manufacturing equipment and tooling.




<PAGE>   10


Our ability to introduce new products on a timely basis is an important factor
in our success. New products have lower manufacturing yields and are produced in
lower quantities than more mature products. Our dedicated development center
enables us to shorten development cycles and achieve high volume output per
manufacturing unit more quickly. Manufacturing yields generally improve as the
product matures and production volumes increase. Manufacturing yields also vary
depending on the complexity and uniqueness of product specifications. Because
our business is capital intensive and requires a high level of fixed costs,
gross margins are also extremely sensitive to changes in volume. Small
variations in capacity utilization or manufacturing yields generally have a
significant impact on gross margins.

We typically allow customers to change or cancel orders on short notice without
penalty. We plan our production and inventory based primarily on forecasts of
customer demand, including forecasts of customer pulls of product out of our
"just-in-time" inventory hubs, rather than on order backlog. Both customer
demand and the resulting forecasts often fluctuate substantially. These factors,
among others, create an environment where scheduled production and capacity
utilization can vary significantly from week to week, leading to variability in
gross margins and difficulty in estimating our market share.

In addition to increases in suspension assembly demand, improvements to our
operating margins depend, in part, on the successful management of our corporate
infrastructure, our suspension assembly production capacity and our workforce.
During the past two years, we consolidated some of our manufacturing operations
to make better use of existing equipment and support staff across all of our
plants and to reduce costs. As part of our efforts to improve our operating
margins through reduced costs and improved efficiency, we reduced our overall
employment level through workforce reductions and managed attrition, from 7,701
at the end of 1999 to 4,189 at the end of the second quarter of 2001.

During the second quarter of 2001, we reduced our employment level by 502
employees, including approximately 350 positions that were eliminated in
manufacturing, development and manufacturing support at all plant sites.
Employees whose positions were eliminated were offered a severance package, and
the full amount of the severance costs has been paid.

RESULTS OF OPERATIONS

THIRTEEN WEEKS ENDED MARCH 25, 2001 VS. THIRTEEN WEEKS ENDED MARCH 26, 2000.

Net sales for the thirteen weeks ended March 25, 2001 were $95,737,000, a
decrease of $15,200,000 or 14% from the comparable period in 2000. The decrease
was primarily due to lower suspension assembly sales volume, somewhat offset by
higher average selling prices.

Gross profit for the thirteen weeks ended March 25, 2001 was $5,803,000,
compared to $4,442,000 for the comparable period in 2000. Gross profit as a
percent of net sales increased from 4% to 6%, primarily due to lower
manufacturing labor and benefits expenses as a result of the workforce
reductions and improvements in manufacturing productivity and yield that have
occurred during 2000 and 2001, offset in large part by the lower sales volume
noted above.

Selling, general and administrative expenses for the thirteen weeks ended March
25, 2001 were $15,140,000, an increase of $2,204,000 or 17% from the comparable
period in 2000. The increase was due primarily to severance charges of
$2,364,000 and increased legal and professional fees of $867,000, partially
offset by lower labor and benefits expenses due to workforce reductions.
Excluding severance charges, selling, general and administrative expenses as a
percent of net sales, increased from 11% in the second quarter of 2000 to 13% in
the second quarter of 2001.



<PAGE>   11


Research and development expenses for the thirteen weeks ended March 25, 2001
were $5,493,000 compared to $5,637,000 for the thirteen weeks ended March 26,
2000. As a percent of net sales, research and development expenses increased
from 5% in the second quarter of 2000 to 6% in the second quarter of 2001.

Interest expense for the thirteen weeks ended March 25, 2001 was $3,992,000, an
increase of $502,000 from the comparable period in 2000, primarily due to
interest expense on capitalized leases of $653,000.

Other income, net, for the thirteen weeks ended March 25, 2001 was $3,678,000,
an increase of $584,000 from the comparable period in 2000. The increase was
primarily due to an increase in interest income as a result of a higher
investment balance.

The income tax benefit for the thirteen weeks ended March 25, 2001 was based on
an estimated effective tax rate for the fiscal year of 10%, which is below the
statutory federal rate primarily due to alternative minimum tax considerations
and uncertainty related to the Company's ability to offset future income with
net operating losses.

Net loss for the thirteen weeks ended March 25, 2001 was $13,630,000, compared
to a net loss of $13,101,000 for the comparable period in 2000. As a percent of
net sales, the net loss increased from (12)% for the thirteen weeks ended March
26, 2000 to (14)% for the thirteen weeks ended March 25, 2001.

TWENTY-SIX WEEKS ENDED MARCH 25, 2001 VS. TWENTY-SIX WEEKS ENDED MARCH 26, 2000.

Net sales for the twenty-six weeks ended March 25, 2001 were $214,651,000, a
decrease of $20,109,000 or 9% from the comparable period in 2000. This decrease
was primarily due to lower suspension assembly sales volume, somewhat offset by
higher average selling prices.

Gross profit for the twenty-six weeks ended March 25, 2001 was $25,697,000,
compared to $12,425,000 for the comparable period in 2000, and gross profit as a
percent of net sales increased from 5% to 12%. This increase was primarily due
to lower manufacturing labor and benefits expenses as a result of the workforce
reductions and improvements in manufacturing productivity and yield that have
occurred during 2000 and 2001, offset in large part by the lower sales volume
noted above.

Selling, general and administrative expenses for the twenty-six weeks ended
March 25, 2001 were $27,892,000, an increase of $3,647,000 or 15% from the
comparable period in 2000. The increase was due primarily to severance charges
of $2,364,000 and increased legal and professional fees of $1,565,000, partially
offset by lower labor and benefits expenses due to workforce reductions.
Excluding severance charges, selling, general and administrative expenses as a
percent of net sales, increased from 10% for the twenty-six weeks ended March
26, 2000 to 12% for the twenty-six weeks ended March 25, 2001.

Research and development expenses for the twenty-six weeks ended March 25, 2001
were $12,001,000 compared to $11,178,000 for the twenty-six weeks ended March
26, 2000. The increase was mainly due to increased advanced suspension
development expenses. As a percent of net sales, research and development
expenses increased from 5% for the twenty-six weeks ended March 26, 2000 to 6%
for the twenty-six weeks ended March 25, 2001.

During the first quarter of 2000, we recorded a charge of $46,528,000 to write
down certain assets and record severance costs for approximately 250 employees
terminated during the quarter. Components of the charge included a $43,528,000
asset write-down of impaired manufacturing equipment and tooling, primarily for
our TSA suspensions, and $3,000,000 of severance costs. See Note 3, "Asset
Impairment and Other", in the notes to the condensed consolidated financial
statements.

Interest expense for the twenty-six weeks ended March 25, 2001 was $7,965,000,
an increase of $1,476,000 from the comparable period in 2000, primarily due to
interest expense on capitalized leases of $1,338,000.

Other income, net, for the twenty-six weeks ended March 25, 2001 was $7,811,000,
an increase of $1,490,000 from the comparable 2000 period. This increase was
primarily due to an increase in interest income as a result of a higher
investment balance and higher investment yields.

The income tax benefit for the twenty-six weeks ended March 25, 2001 was based
on an estimated effective tax rate for the fiscal year of 10%, which is below
the statutory federal rate primarily due to alternative minimum tax
considerations and uncertainty related to the Company's ability to offset future
income with net operating losses.

Net loss for the twenty-six weeks ended March 25, 2001 was $12,915,000, compared
to a net loss of $52,270,000 for the comparable period in 2000. The 2000 net
loss included the above-mentioned asset write-down. Excluding the asset
write-down in the first quarter of 2000 and severance costs in the second
quarter of both 2000 and 2001, the net loss as a percent of net sales, decreased
from (7)% for the twenty-six weeks ended March 26, 2000 to (5)% for the
twenty-six weeks ended March 25, 2001.

Our cash and cash equivalents increased from $129,314,000 at September 24, 2000
to $168,552,000 at March 25, 2001. Our securities available for sale decreased
from $110,955,000 to $84,796,000 during the same period. Overall, this reflects
a $13,079,000 increase in our cash and cash equivalents and securities available
for sale. We generated cash from operating activities of $43,087,000 for the
twenty-six weeks ended March 25, 2001.

As of March 25, 2001, our $50,000,000 credit facility had a borrowing base of
$46,836,000, secured by our accounts receivable and inventory. Letters of credit
outstanding under this facility totaled $15,542,000 as of such date, including
$813,000 issued as security for our $800,000 variable rate demand note,
$14,104,000 issued in connection with obligations under equipment leases, and
$625,000 issued to support potential self-insured workmens' compensation
obligations. No other letters of credit were outstanding under the credit
facility at March 25, 2001. The amount we can borrow under this credit facility
is limited by the levels of our accounts receivable and inventory balances. As
of March 25, 2001, $31,268,000 of borrowing capacity remained available to us.

Cash used for capital expenditures totaled $16,525,000 for the twenty-six weeks
ended March 25, 2001. We currently anticipate spending approximately $35,000,000
during 2001 primarily for program tooling and manufacturing and process
technology and equipment. Financing of these capital expenditures will be
principally from internally generated funds, cash and cash equivalents and
securities available for sale.

Certain of our existing financing agreements contain financial covenants and
covenants which may restrict our ability to enter into certain types of
financing. We were in compliance with all such covenants at March 25, 2001. If
we are not in compliance with financial covenants in our financing agreements at
the end of any quarter, our future financial results and liquidity could be
materially adversely affected.

We currently believe that our cash and cash equivalents, securities available
for sale, cash generated from operations and credit facility will be sufficient
to meet our operating expenses, debt service requirements and capital
expenditures through 2001. We will pursue additional debt or equity financing to
supplement our current capital resources if needed beyond 2001. Our ability to
obtain additional financing will depend upon a number of factors, including our
future performance and financial results and general economic and capital market
conditions. We cannot be sure that we will be able to raise additional capital
on reasonable terms or at all.

MARKET TRENDS AND CERTAIN CONTINGENCIES

(a) MARKET TRENDS

We expect the expanding use of personal computers, enterprise computing and
storage, increasingly complex software and the emergence of new applications for
disk storage, such as Internet-related storage, digital video recording, digital
cameras, network attached storage, gaming consoles and other consumer
applications, will further increase disk drive demand and therefore, suspension
demand, in the future. We also believe demand for disk drives will continue to
be subject, as it has in the past, to rapid or unforeseen changes resulting
from, among other things, changes in disk drive inventory levels, technological
advances, responses to competitive price changes and unpredicted high or low
market acceptance of new drive models. Improvements in data density of hard disk
drives, extending from the desktop market to server drives, have reduced unit
shipments of suspension assemblies since the third quarter of 1999. Suspension
assembly shipments were significantly lower in quarter two compared to quarter
one of 2001 due to the lingering effects of slower holiday season sales,
concerns about a weak economy, and previous overbuying by businesses. In the
third quarter of 2001, we expect our unit shipments to be relatively flat to
down somewhat from the second quarter of 2001.

As in past years, disk drives continue to be the storage device of choice for
applications requiring low access times and higher capacities because of their
speed and low cost per megabyte of stored data. The cost of storing data on disk
drives continues to decrease primarily due to increasing data density, the
amount of data which can be stored on magnetic disks, thereby reducing the
number of components, including suspensions, required in a disk drive.

Improvements in data density have been attained by lowering the fly height of
the read/write head, using smaller read/write heads with advanced air bearing
designs, improving other components such as motors and media, and using new
read/write head types such as those of magneto-resistive (MR) and giant
magneto-resistive (GMR) design. The move to MR and GMR heads, which require more
electrical leads, and the transition to smaller pico-sized heads, which are more
sensitive to mechanical variation, have compelled drive manufacturers to use
wireless suspension technologies, such as our TSA suspension assemblies. Our TSA
suspension assemblies are being widely adopted within the disk drive industry.

The continual pursuit of increasing data density and lower storage costs are
leading to further value-added features for TSA suspensions, such as extended
electrical leads (tails) and switch shunts. A switch shunt helps our customers
prevent damage to the sensitive recording heads by reducing the risk of



<PAGE>   14



electrostatic discharge. Additionally, dual stage suspensions, including our
aTSA suspension, incorporate a second stage actuator on the suspension to
improve head positioning over increasingly tighter data tracks. Our cTSA
suspension allows for attachment of preamplifiers near the head to improve data
transfer signals.

The introduction of new types or sizes of read/write heads and new disk drive
designs tends to initially decrease customers' yields with the result that we
may experience temporary elevations of demand for some types of suspension
assemblies. Likewise, as programs mature, higher yields decrease the demand for
suspension assemblies. The advent of new heads and new drive designs may require
rapid development and implementation of new suspension types which temporarily
may reduce our manufacturing yields and efficiencies. There can be no assurance
that we will not continue to be affected by such changes.

We generally experience fluctuating selling prices due to competitive pricing
pressures, product maturity, and new product offerings. While many of our
current products are reaching or are in the mature phase of their life cycles
and thus are experiencing declining selling prices, our newer products initially
have higher selling prices.

(b) CONTINGENCIES

On September 18, 2000, we commenced a lawsuit in the United States District
Court for the District of Minnesota against the Magnecomp Group, an
unincorporated association of companies, and seven members of the Magnecomp
Group. The lawsuit alleges that the Magnecomp Group has sold infringing products
without a license, and alleges infringement of nine of our patents related to
the design and manufacture of suspension assemblies. The lawsuit requests
damages, including treble damages, attorneys' fees, costs, and an injunction
against the Magnecomp Group.

On October 12, 2000, Magnecomp Corporation commenced a lawsuit in the United
States District Court for the Central District of California against us. The
lawsuit alleges that we sold products infringing four patents, engaged in
anti-competitive conduct in violation of federal and state antitrust laws, and
violated California state law regarding contractual interference and unfair
competition. The lawsuit requests damages, including treble damages, attorneys'
fees, costs, punitive damages, and an injunction against us. On December 8,
2000, the California District Court issued an order granting our motion to
transfer the California action to the United States District Court for the
District of Minnesota.

The two lawsuits described above have been consolidated for pre-trial purposes,
and both currently are in the discovery phase.

We and certain users of our products have from time to time received, and may in
the future receive, communications from third parties asserting patents against
us or our customers which may relate to our manufacturing equipment or to our
products or to products that include our products as a component. We are
currently a party to the litigation described above. In addition, certain of our
customers have been sued on patents having claims closely related to products we
sell. If any third party makes a valid infringement claim and a license were not
available on terms acceptable to us, our operating results could be adversely
affected. We expect that, as the number of patents issued continues to increase,
and as we grow, the volume of intellectual property claims could increase. We
may need to engage in litigation to enforce patents issued or licensed to us,
protect trade secrets or know-how owned by us or determine the enforceability,
scope and validity of the intellectual property rights of others. We could incur
substantial costs in such litigation or other similar legal actions, which could
have a material adverse effect on our results of operations.

We are a party to certain other claims arising in the ordinary course of
business. In our opinion, the outcome of such claims will not materially affect
our current or future financial position or results of operations.

(c)  OTHER MATTERS

In early calendar 2000, the World Trade Organization ("WTO") ruled that the
United States Foreign Sales Corporation ("FSC") provision constituted an illegal
export subsidy, and specified that the United States withdraw the FSC provision
effective October 1, 2000. In response to the ruling, the United States
government enacted The Extraterritorial Income Exclusion ("EIE") Act in November
of 2000. The United States believes this is a WTO-compatible solution. A ruling
from the WTO on the EIE is not expected to be issued until late spring or summer
of calendar 2001. We do not expect that the new legislation will change
materially the tax benefit that we earn.

FORWARD-LOOKING STATEMENTS

The statements above under the headings "General" and "Market Trends and Certain
Contingencies" about demand for and shipments of disk drives and suspension
assemblies, including TSA suspensions, manufacturing capacity and yields and
selling prices, and the statements above under the heading "Liquidity and
Capital Resources" about capital expenditures and capital resources, are
forward-looking statements based on current expectations. These statements are
subject to risks and uncertainties, including slower or faster customer
acceptance and adoption of new product features, fluctuating order rates, faster
or slower improvements in disk drive data densities which affect suspension
assembly demand, changes in market consumption of disk drives or suspension
assemblies, difficulties in producing our TSA suspensions, difficulties in
managing capacity, changes in manufacturing efficiencies and the other risks and
uncertainties discussed above. These factors may cause our actual future results
to differ materially from historical earnings and from the financial performance
we presently anticipate.

       ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

Our credit facility with The CIT Group/Business Credit, Inc. carries interest
rate risk, in connection with certain borrowings under the working capital line
it provides, that is generally related to either LIBOR or the prime rate. If
either of these rates were to change while we had such borrowings outstanding
under the working capital line provided by the credit facility, interest expense
would increase or decrease accordingly. At March 25, 2001, there were $25,500 in
outstanding borrowings under the working capital line provided by the credit
facility. Our variable rate demand note ("Note") also carries interest rate risk
that is generally related to the 91-day U.S. treasury bill interest rate. At
March 25, 2001, the outstanding principal amount of the Note was $800,000 which
was subject to an interest rate of 3.55%.

We have no earnings or cash flow exposure due to market risk on our other debt
obligations which are subject to fixed interest rates. Interest rate changes,
however, would affect the fair market value of this fixed rate debt. At March
25, 2001, we had fixed rate debt of $203,298,000.

We do not enter into derivative or other financial instruments for trading or
speculative purposes. All of our sales transactions are denominated in U.S.
dollars and thus are not subject to risk due to currency exchange fluctuations.
