at exercise prices ranging from $17.82 to $35.50 were outstanding at April 3,
2004, and March 29, 2003, respectively, but were not included in the computation
of diluted earnings per share because the options' exercise prices were greater
than the average market price of the common shares and, therefore, the options
would have no dilutive effect.

6. TECCOR ACQUISITION

On July 7, 2003, the Company completed the acquisition of all of the outstanding
stock of Teccor Electronics, Inc., a subsidiary of Invensys plc (`Teccor') for
$44.6 million in cash, plus a future payment of $5.0 million contingent on sales
of Teccor products reaching $107.0 million for calendar year 2005.

Teccor manufactures semiconductor products for the telecommunications and
industrial market segments, including transient voltage suppression devices and
power switching devices. The addition of Teccor's transient voltage suppression
products expands the Company's line of overvoltage products and strengthens its
position in the telecom and industrial market segments.

The acquisition was accounted for using the purchase method and the operations
of Teccor are included in the Company's operations from the date of acquisition.
The allocation of the purchase price resulted in no goodwill.

                                       9


The acquisition was funded with cash on hand and borrowings under the Company's
$50.0 million revolving credit facility.

In connection with the acquisition of Teccor Electronics and at the time of the
acquisition, the Company recorded purchase accounting liabilities of $6.9
million primarily for redundancy costs related to manufacturing operations and
selling, general and administrative functions. Included in this amount is $0.7
million to reflect the obligation of Teccor to remit proceeds from the sale of
land to the former owners. As of April 3, 2004, changes to the purchase
accounting liability include a $4.4 million payment related to employee
severance, a $1.6 million reserve adjustment and a $0.7 million payment to remit
proceeds from the sale of land to the former owners, leaving a purchase
accounting restructuring liability balance of $0.2 million at April 3, 2004. The
remaining accrued liabilities are expected to be paid by the end of the 2004
fiscal year. The following unaudited pro forma consolidated financial

These unaudited pro forma results are presented for comparative purposes only.
The pro forma results are not necessarily indicative of what actual results
would have been had the acquisition been completed as of the beginning of the
respective period, or of future results.

7.    DERIVATIVES AND HEDGING

On June 11, 2002, the Company entered into cross currency rate swaps, with a
notional amount of $11.6 million, as a cash flow hedge against the variability
of Yen cash flows attributable to the exchange rate risk on forecasted
intercompany sales of inventory to a Japanese subsidiary. The cross currency
rate swaps convert a portion of the Company's US Dollar fixed rate debt to fixed
rate Japanese Yen debt. The swap agreements were accounted for as a cash flow
hedge and reported at fair value. The notional amount outstanding at April 3,
2004, was $6.0 million and the fair value of the outstanding cross currency rate
swap agreements was recognized as a $1.1 million liability and as a charge to
comprehensive loss in the Consolidated Balance Sheet at April 3, 2004.

Derivative financial instruments involve, to a varying degree, elements of
market and credit risk not recognized in the consolidated financial statements.
The market risk associated with these instruments resulting from interest rate
movements is expected to offset the market risk of the underlying transactions
being hedged. The counterparties to the agreements relating to the Company's
cross currency rate instruments consist of major international financial
institutions with high credit ratings. The Company does not believe that there
is significant risk of non-performance by these counterparties because the
Company monitors the credit ratings of such counterparties, and limits the
financial exposure and amount of agreements entered into with any one financial
institution. While the notional amount of the derivative financial instruments
provide one measure of the volume of these transactions, they do not represent
the amount of the Company's exposure to credit risk. The amounts potentially
subject to credit risk (arising from the possible inability of counterparties to
meet the terms of their contracts) are generally limited to the amounts, if any,
by which the counterparties' obligations under the contracts exceed the
obligations of the Company to the counterparty.

The expected rate of return on pension plan assets is 8.75% in 2004 and 2003.

9. COMPREHENSIVE INCOME

Total comprehensive income for the three months ended April 3, 2004, and
March 29, 2003, was approximately $9.3 and $3.5 million, respectively. The
adjustment for comprehensive income consists of deferred gains and losses from
foreign currency translation adjustments and qualified cash flow hedges and
unrealized gains and losses on available-for-sale securities.

11. NEW ACCOUNTING STANDARDS

In December 2003, the FASB issued revised Statement No. 132 (SFAS 132).
"Employers' Disclosures about Pensions and Other Postretirement Benefits." The
revised SFAS 132 requires additional disclosures about the plan obligations and
components of net periodic benefit cost recognized during interim periods. This
Statement is effective for financial statements with fiscal years ending after
December 15, 2003 and interim periods beginning after December 15, 2003. The
Company adopted the interim disclosure requirements effective January 1, 2004.
The adoption did not have any impact on the Company's financial position or
results of operations.

12. SUBSEQUENT EVENT

On May 6, 2004, the Company entered into a definitive agreement to acquire an
82% stake in Heinrich Industrie AG for (euro)39.5 million (approximately $47.2
million) in cash. Pursuant to this agreement, the Company purchased the
controlling interest in Heinrich Industrie from the company's two largest
shareholders. The Company also intends to promptly initiate a tender offer for
the remaining shares of this publicly held company. The transaction will be
financed through cash on hand and use of the Company's existing credit facility.

RESULTS OF OPERATIONS
First Quarter, 2004

Sales for the first quarter 2004 increased 59% or $41.4 million to $111.4
million, compared to $70.0 million in the first quarter of 2003. The increase
was driven by sales of $24.4 million from Teccor, which was acquired July 7,
2003. Excluding Teccor, sales for the first quarter 2004 increased 24% compared
to the first quarter of 2003.

On a geographic basis, sales in the Americas increased $18.5 million or 53% in
the first quarter of 2004, as Teccor added $11.6 million for the quarter.
Excluding Teccor, sales in the Americas increased $6.9 million or 19.9%, due to
strengthening automotive, electronic and electrical markets compared to last
year. Europe sales increased $7.6 million or 57% in the first quarter of 2004 as
Teccor added $4.3 million and favorable currency added $2.3 million. Asia sales
increased $15.3 million or 70% compared to the prior year first quarter, due to
$8.5 million of sales from Teccor, favorable currency effects of $0.9 million
and strengthening Asian demand for digital consumer products.

                                       14


Electronic sales increased $37.3 million or 100% to $74.5 million in the first
quarter of 2004 from $37.2 million in the same quarter of last year with $24.4
million of the increase due to Teccor. Excluding Teccor, electronic sales
increased $12.9 million or 35% to $50.1 million compared to $37.2 million in the
prior year quarter. Electronic sales increased in the Asia region, primarily due
to increased demand for consumer electronics, notebook computers and handheld
products. The electronic markets in North America and Europe also improved
compared to the same period in the prior year due primarily to recoveries in the
telecom and industrial markets.

Automotive sales increased $3.6 million or 15% to $28.2 million in the first
quarter of 2004 compared to $24.6 million in the same quarter last year. North
America automotive sales were favorably impacted by product sold to a large OEM
customer in support of a recall program and Europe automotive sales benefited
from favorable currency effects.

Electrical fuse sales increased $0.5 million or 6% to $8.7 million in the first
quarter 2004 from $8.2 million in the same quarter last year. The electrical
fuse market has begun to show signs of improvement as industrial markets begin
to recover. The other key market, non-residential construction, remains weak.

Gross margin was $39.8 million or 35.7% of sales for the first quarter of 2004
compared to $23.1 million or 33.0% in the same quarter last year. The increase
in gross margin as a percent of sales was due to progress related to the Teccor
integration, operating leverage resulting from higher sales, cost reductions in
excess of price erosion and favorable currency effects.

Total operating expenses were $24.1 million or 21.6% of sales for the first
quarter of 2004 compared to $17.8 million or 25.5% of sales for the same quarter
last year. The reduction in operating expenses as a percent of sales reflects
improved expense leverage resulting from the Teccor acquisition.

Operating income increased to $15.7 million or 14.1% of sales in the first
quarter of 2004 compared to $5.2 million or 7.5% in the prior year. Operating
income increased due to higher sales, increased gross margin and reduced
operating expenses as a percent of sales as explained above.

Interest expense was $0.4 million in the first quarter of this year compared to
$0.5 million in the first quarter of last year due to lower debt levels. Other
expense was $0.3 million for the first quarter of 2004 compared to other income
of $0.3 million in the first quarter of the prior year. The prior year includes
a $0.2 million gain related to the sale of a Korean manufacturing site.

Income before income taxes was $15.0 million for the first quarter 2004 compared
to $5.0 million for the first quarter of 2003. Income taxes were $5.4 million
with an effective tax rate of 36% for the first quarter of 2004 compared to $1.8
million with an effective tax rate of 36% in the first quarter of last year.

Net income increased to $9.6 million in the first quarter this year compared to
$3.2 million in the first quarter of last year and diluted earnings per share
increased to $0.43 in the first quarter this year compared to $0.15 per diluted
share in the same quarter last year.

                                       15


LIQUIDITY AND CAPITAL RESOURCES

Assuming no material adverse changes in market conditions , management expects
that the Company will have sufficient cash from operations to support both its
operations and its current debt obligations for the foreseeable future.

Littelfuse started the 2004 year with $22.1 million of cash. Net cash provided
by operations was $2.9 million for the first three months. Net cash used in
investing activities included $3.0 million in purchases of property, plant and
equipment. In addition, net cash provided by financing activities included stock
option exercises of $1.9 million. The net cash provided by operations, less
investing and financing activities, resulted in a $1.8 million net increase in
cash. This left the Company with a cash balance of $23.9 million at April 3,
2004.

The ratio of current assets to current liabilities was 2.0 to 1 at the end of
the first quarter 2004 compared to 1.8 to 1 at year-end 2003 and 2.4 to 1 at the
end of the first quarter 2003. The days sales in receivables was approximately
49 days at the end of the first quarter 2004, compared to 50 days at year-end
2003, and 56 days at the end of the first quarter 2003. The days inventory
outstanding was approximately 69 days at the end of the first quarter 2004
compared to 71 days at year-end 2003 and 91 days at end of the first quarter
2003.

The Company's net capital expenditures were $3.0 million for the first quarter
2004. Included in this amount were expenditures for plant expansions in China
and equipment related to capacity increases and cost reduction.

Total debt at the end of the first quarter 2004 totaled $28.8 million and
consisted of the following: (1) 6.16% private placement notes totaling $20.0
million, (2) foreign revolver borrowings totaling $8.5 million, and (3) notes
payable relating to mortgages totaling $0.3 million. Of this indebtedness, $18.7
million is considered to be current liabilities. The Company has a $50.0 million
in the U.S., of which $50.0 million was available at April 3, 2004. The
revolving bank credit agreement has an interest rate of prime or LIBOR plus
0.875%. The Company also had $1.9 million in letters of credit outstanding at
April 3, 2004.

OUTLOOK

Sales in 2004 are expected to improve slightly in the automotive and electrical
markets. Sales in the electronics market are expected to show steady growth,
particularly in Asian markets. As these markets improve, the Company believes
its long-term growth strategy, which emphasizes development of new circuit
protection products and providing customers with solutions and technical support
in all major regions of the world, will drive sales growth in all of its
markets.

The Company will initiate a new series of projects in 2004 to consolidate and
reduce costs in its global manufacturing and distribution operations. These
programs are expected to generate sufficient cost savings to more than offset
price erosion in 2004. The Company also plans to increase research and
development spending to accelerate new product development in order to help
drive future sales growth. The benefits of incremental volume improvements and
cost savings are expected to continue to have a favorable impact on earnings in
2004.

                                       16



The Company is working to expand its market share in the overvoltage circuit
protection market with the addition of products and technology through the
Semitron Industries, Harris Suppression Products, Teccor and Heinrich Industrie
AG acquisitions and the ability to offer customers total circuit protection
solutions. The Company remains committed to investing in new product development
and technical resources to provide customers with overcurrent and overvoltage
circuit protection solutions and expertise.

1995

The statements in this section and in the other sections of this report which
are not historical facts contained in this report are forward-looking statements
that involve risks and uncertainties, including, but not limited to, product
demand and market acceptance risks, the effect of economic conditions, the
impact of competitive products and pricing, product development and patent
protection, commercialization and technological difficulties, capacity and
supply constraints or difficulties, exchange rate fluctuations, actual purchases
under agreements, the effect of the Company's accounting policies, labor
disputes, restructuring costs in excess of expectations, pension plan asset
returns less than assumed, and other risks which may be detailed in the
Company's Securities and Exchange Commission filings. Should one or more of
these risks or uncertainties materialize or should the underlying assumptions
prove incorrect, actual results and outcomes may differ materially from those
indicated or implied in the forward-looking statements. This report should be
read in conjunction with information provided in the financial statements
appearing in the Company's Annual Report on Form 10-K for the year ended January
3, 2004.

ITEM 3. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

The Company is exposed to market risk from changes in foreign exchange rates,
commodities and to a lesser extent, interest rates.

The Company had long-term debt outstanding at April 3, 2004, in the form of
fixed rate private placement notes, a U. S. variable rate revolving line of
credit and foreign lines of credit at variable interest rates. Approximately 69%
of the Company's long-term debt is at fixed rates and primarily consists of bank
loans and mortgages. The Company does not enter into derivative transactions
(i.e., interest rate swaps) with respect to its long-term debt, as the current
interest expense on this debt is not deemed material to operations.

A portion of the Company's operations consists of manufacturing and sales
activities in foreign countries. The Company has manufacturing facilities in
Mexico, England, Ireland, Switzerland, China and the Philippines. Substantially
all sales in Europe are denominated in British Pounds Sterling, United States
Dollars and Euros and substantially all sales in the Asia-Pacific region are
denominated in United States Dollars, Japanese Yen and South Korean Won.

The Company's identifiable foreign exchange exposures result from the purchase
and sale of products from affiliates, repayment of intercompany trade and loan
amounts and translation of local currency amounts in consolidation of financial
results. Changes in foreign currency exchange rates or weak economic conditions
in the foreign countries in which it manufactures and distributes products could
affect the Company's sales and financial results. The Company primarily utilizes

                                       17



netting and offsets to reduce known foreign currency exposures and, when
appropriate, derivative instruments as hedges of specific foreign currency cash
flows.

The Company has entered into cross currency rate swaps with a notional amount of
$11.6 million. The cross currency swaps convert $11.6 million of the Company's
fixed rate 6.16% U.S. Dollar debt to fixed rate 3.13% Japanese Yen debt. The
fair value of the rate swap agreements outstanding at April 3, 2004, which had a
notional amount of $6.0 million, was recognized as a $1.1 million liability, and
is reported in consolidated shareholders' equity as a component of other
comprehensive income.

A risk management policy has been implemented by the Company that describes the
procedures and controls over derivative financial instruments. Under the policy,
the Company does not use derivative financial instruments for trading purposes
and the use of such instruments is subject to the approval of senior officers.
Typically, the use of such derivative instruments is limited to hedging
activities related to specific foreign currency cash flows. The Company's
exposure related to such transactions is, in the aggregate, not material to the
Company's financial position, results of operations and cash flows.

The Company uses various metals in the production of its products, including
zinc, copper and silver. The Company's earnings are exposed to fluctuations in
the prices of these commodities. The Company does not currently use derivative
financial instruments to mitigate this commodity price risk.
