TO
THE BOARD OF DIRECTORS
HEINRICH INDUSTRIE AG
ANNENSTRA(BETA)E 113
58453 WITTEN

We have audited the accompanying consolidated balance sheet of HEINRICH
INDUSTRIE AG and its subsidiaries as of December 31, 2003, and the related
consolidated statement of income, for the period from January 1, 2003 to
December 31, 2003. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of HEINRICH INDUSTRIE
AG and its subsidiaries at December 31, 2003, and the results of their
operations for the period from January 1, 2003 to December 31, 2003 in
conformity with accounting principles generally accepted in Germany.

NOTES TO FINANCIAL STATEMENTS OF HEINRICH INDUSTRIE GROUP FOR 2003

The Group financial statements of HEINRICH INDUSTRIE AG are prepared in
accordance with the requirements of the German commercial code relating to
capital companies.

      1.    CONSOLIDATED GROUP

HEINRICH INDUSTRIE AG is the holding company for the Wickmann Group of circuit
protection products, which has three business units: electronic, automotive and
electrical. Littelfuse operates HEINRICH in such business units subsequent to
the acquisition.

In addition to the financial statements of HEINRICH INDUSTRIE, the group
statements for 2003 contain the individual statements of 6 (previous year 6)
domestic and 7 (previous year 8) foreign companies.

The EFEN-Vertriebs GmbH, Salzburg/Austria, was liquidated in the business year
2003. The deletion from the company register was made on July 4, 2003. The
de-consolidation of the company took place at the start of the year.

The following companies

-     Motherson PUDENZ WICKMANN Ltd., New Delhi, India

-     Hinnenberg Beteiligungsgesellschaft mbH i.L., Essen

-     Switchgear Systems Ltd., Rugby/ Warwickshire, Great Britain

have not been included in the group statement in accordance with Section 296
Para. 2 HGB and Section 311 Para. 2 HGB due to the minor importance of the
companies to the asset, financial and revenue situation of the group.

The companies included in the group statements are listed under Point 7. The
business year of all companies included is the calendar year.

2.    CONSOLIDATION PRINCIPLES

The balance sheets of HEINRICH INDUSTRIE and the subsidiary companies included
in the statements are consolidated in the group statements. The asset and
liability items have been used instead of the shareholding book values, at the
values used in the balance sheets of the individual companies as at December 31,
2003.

For capital consolidation the purchase method is applied by eliminating the
purchase price of the participating interests acquired against the company's
share in net assets of these companies. Any resulting goodwill is recognized in
the earning reserves at the time of initial consolidation, any negative goodwill
is added to the earning reserves.

Loans and other receivables, liabilities, revenue as well as income and expenses
incurred on intercompany transactions and any resulting intercompany profit are
eliminated. For consolidation procedures affecting net income, deferred taxes
have been recorded.

3.    CURRENCY TRANSLATION

The balance sheets of the subsidiaries that are compiled in a foreign currency
have been translated and included in the group statements as follows:

-     The translation of the shareholders' equity and the ASSET AND LIABILITY
      ITEMS of the balance sheets has been made uniformly at the exchange rate
      prevailing on the balance sheet date.

-     Items of the INCOME STATEMENT have been translated at the average exchange
      rate over the business year.

-     The balance of exchange rate differences has been recognized in the
      earning reserves of the group balance sheet, not affecting the result.

Currency translation differences resulting from the consolidation of
intercompany income and expense are included in the income statement.

4.    ACCOUNTING AND VALUATION PRINCIPLES

The annual statements of the individual companies have been compiled in
accordance with legal requirements and the applicable balance sheet and
valuation methods of HEINRICH INDUSTRIE.

The INTANGIBLE ASSETS are shown at purchase price, less scheduled linear
amortization and impairments.

The FIXED ASSETS have been valued at purchase price or cost of production, less
scheduled depreciation according to use and impairments. The impairments

                                       8



consist of impairment adjustments to the lower fair value and special tax
depreciation.

Scheduled depreciation has been applied linearly or declining at the maximum
rates permitted by tax regulations. In the case of movable assets, depreciation
is generally applied declining at first, with a transition to linear
depreciation as soon as this leads to higher depreciation amounts. The
depreciation is based on a useful life of up to 50 years for buildings, and 3 to
13 years for technical equipment and machinery, other plant, operating and
business equipment. Low-value goods are written off completely in the year of
acquisition.

The SHARES IN AFFILIATED COMPANIES of HEINRICH INDUSTRIE have been valued at
purchase price, and where applicable less impairments in accordance with Section
3 of the law governing tax measures for the closure of coal mines.

The PARTICIPATING INTERESTS are shown at their purchase price.

Interest-bearing LOANS are shown at the nominal value. Where allowed by tax
regulations, loans granted interest-free up to 1954 have been fully adjusted in
value. Other interest-free loans have been valued at the cash value, taking into
account an interest rate of 5.5% p.a.

In the case of INVENTORIES, raw materials and operating materials and goods have
been valued at their purchase price. Unfinished and finished goods have been
valued at cost of production or the lower fair market value. In addition to
material and individual production costs, the manufacturing costs also include
general material and production costs and depreciation. The lower of cost or
market principle has been applied. Sufficient reductions in value have been
recorded to account for risks resulting from the duration of storage or reduced
realizability. In accordance with applicable tax regulations, the valuation of
stocks has generally been made according to the "LIFO" method.

RECEIVABLES AND OTHER ASSETS have been valued at the nominal value, with
individual adjustments made to take account of discernible risks. The general
credit risk has been taken into account by means of a general reserve.
Receivables in foreign currency are shown at the exchange rate prevailing at the
time of the transaction or on the balance sheet date, whichever is the lower.

The PENSION ACCRUALS have been calculated according to the guideline tables of
Dr. Klaus Heubeck of 1998 on the basis of an interest rate of 6%. The
calculation has been made in accordance with Section 6a EStG.

The ACCRUALS FOR FORMER COAL-MINING have been calculated in accordance with the
agreements made with the financial administration at the cash value of the costs
to be anticipated for the future, or in the case of long-term damage at 20-times
the average annual cost.

The TAX AND OTHER ACCRUALS take into account all discernible risks and uncertain
liabilities.

The LIABILITIES are listed at their repayment amounts. Liabilities in foreign
currency are shown at the exchange rate prevailing at the time of the
transaction or on the balance sheet date, whichever is the higher.

The INCOME STATEMENT has been compiled in graduated form according to the
cost-categories-oriented format.

5.    EXPLANATIONS ON THE BALANCE SHEET

FIXED ASSETS

The development of the fixed assets of the group is shown in the statement of
fixed assets.

The INTANGIBLE ASSETS consist of usage rights (EDP software) and a customer base
obtained from EFEN-Polska on its foundation and from PUDENZ in connection with
the acquisition of OSWALD, and the goodwill shown on the balance sheet of
EFEN-Hungaria. EFEN includes a customer base with a book value of (euro) 1.0
Mio. due to the acquisition of the business operations of Peterreins
Schalttechnik GmbH, Schwabach.

The cumulative depreciation shown under property and buildings contains special
depreciation in accordance with Section 6b EStG. The difference between the
normal linear depreciation and this special depreciation as at December 31, 2003
is (euro) 15.3 Mio within the group. In the business year, this produced a
reduction in annual depreciation of (euro) 0.6 Mio within the group.

In the business year 2003, impairments on fixed assets in the amount of K(euro)
195 (previous year K(euro) 776) were recorded in accordance with Section 253
Para. 2 P. 3 HGB, which refers mainly to operating plant in Witten.

                                       9



In the participating interests, the statement of fixed assets show a reduction
resulting from the sale of the participating interests in Ruhrgas AG. HEINRICH
INDUSTRIE sold its shareholding in Ruhrgas AG by means of the contract of July
2, 2002. The 158,200 shares were acquired by E.ON AG, Dusseldorf. The contract
could not however be completed in the business year 2002, since the required
consent of the general meeting of Ruhrgas AG was not given until February 17,
2003 due to the ongoing proceedings before the regional court of Dusseldorf
against the ministerial permission for the Ruhrgas take-over. WICKMANN increased
its participating interests in the POLYTRONICS Technology Corporation Ltd.,
Hsin-Chu, Taiwan, by the acquisition of 906,000 shares at a purchase price of
K(euro) 929. The POLYTRONICS Technology Corporation Ltd., is a strategic partner
of WICKMANN. The participating interests is aimed at the long-term co-operation
in the "Resettables" sector and provides the right of exclusive marketing of the
relevant products in Europe and North America with ongoing distribution revenue.
The long-term value of the participating interests valuation can be seen in the
group statements, despite the weakness of the Taiwanese Dollar.

The other operating costs include administration costs, allocations to accruals
and also sales and maintenance costs.

The TAXES ON INCOME include current tax liabilities of K(euro) 31 and
liabilities from previous years of K(euro) 14. The current tax liabilities
appear relatively low in comparison to the result from normal business
activities; this is mainly due to the tax-exempt sale of the participating
interests in Ruhrgas AG and the receipt of dividends from foreign subsidiaries.

In the group income statement, the current taxes on income were increased by
K(euro) 29 of deferred taxes (previous year unaudited: decrease by K(euro) 16).

The following income and expenses of items of the income statement result from
affiliated companies:

SUMMARY OF CERTAIN DIFFERENCES BETWEEN GENERALLY ACCEPTED GERMAN AND UNITED
STATES ACCOUNTING PRINCIPLES

The consolidated financial statements of HEINRICH INDUSTRIE have been prepared
in accordance with the German Commercial Code (HGB), as well as various
additional practices, laws and regulations of the Federal Republic of Germany
(collectively German generally accepted accounting principles, "German GAAP").
German GAAP emphasizes the principle of prudence (Vorsichtsprinzip) in the
presentation of the financial statements to protect the interests of creditors.

As a result, HEINRICH INDUSTRIE's consolidated financial statements may differ
substantially from financial statements prepared in accordance with generally
accepted accounting principles in the United States ("U.S. GAAP"). HEINRICH
INDUSTRIE is not required to prepare or present financial statements in
accordance with U.S. GAAP.

The following is a summary of certain differences between German GAAP and U.S.
GAAP as of the dates of HEINRICH INDUSTRIE consolidated financial statements
that may be material. The Company is responsible for preparing the summary
below. The Company has not prepared a complete reconciliation of its
consolidated financial statements and related footnote disclosures between
German GAAP and US GAAP and has not quantified such differences. The discussion
below should not be taken as exhaustive of all differences. No attempt has been
made to identify all disclosures, presentation or classification differences

                                       24


that would affect the manner in which transactions or events are presented in
the consolidated financial statements of HEINRICH INDUSTRIE or notes thereto.

INVESTMENT SECURITIES

Under German GAAP, Heinrich Industrie generally classifies investments in equity
securities as long term financial assets. Such securities are valued based on
the "modified lower of cost or market principle" according to which the historic
cost (the original purchase price) are subject to impairment charges only if a
permanent decline in value is expected.

Under U.S. GAAP, the investments in equity securities are classified into the
categories trading and available-for-sale. Trading and available-for-sale
securities are recorded at fair value. Changes in the fair value of
available-for-sale securities are recognized in other comprehensive income, a
separate component of equity, while changes in the fair value of trading
securities are recognized in the statement of income.

DERIVATIVE INSTRUMENTS AND HEDGE ACCOUNTING

Under German GAAP, derivative instruments and embedded derivatives are generally
accounted for as off-balance-sheet transactions and are disclosed in the notes
to the financial statements. Unrealized gains of both the derivative financial
instrument and hedged items are not recorded on the balance sheet or in the
income statement. However, any unrealised losses on derivatives are recognized
in current income.

Under U.S. GAAP (SFAS 133, "Accounting for Derivative Instruments and Hedging
Activities"), all derivative instruments and embedded derivatives are recorded
on the balance sheet at fair value as either assets or liabilities, regardless
of any hedge relationship that might exist. Changes in the value of derivative
instruments are recognized in the income statement as they arise, unless they
satisfy criteria for hedge accounting (including designation and high
effectiveness), supported by formal documentation. The accounting treatment of
the hedging instruments as well as the hedged items depends on the type of hedge
designation (fair value hedge or cash flow hedge), the offset being in either
current income or other comprehensive income. Also depending on the hedge
designation, the carrying value of the hedged item may need to be adjusted to
offset the changes in the fair value of the hedging derivative. Any
ineffectiveness resulting from the hedge relationship is recognized in income.

ALLOWANCE FOR ACCOUNTS RECEIVABLE

Under German GAAP, allowances related to accounts receivables are stated to
reflect collection risk on a single account basis. The overall credit risk is
considered in a general lump sum allowance for doubtful accounts by taking a 3%
to 5% allowance on the gross amounts not specifically provided for.

Under U.S. GAAP, loss contingencies relating to the collectibility of accounts
receivable are only recorded when certain criteria are met. In accordance with
SFAS 5, "Accounting for Contingencies," contingencies are only recognized when
(a) information available prior to issuance of the financial statements
indicates that it is probable that an asset has been impaired at the date of the
financial statements and (b) the amount of the loss can be reasonably estimated.
General allowances for accounts receivable would require historical evidence in
order to meet the probable and reasonably estimable criteria.

PROPERTY, PLANT AND EQUIPMENT AND INTANGIBLE ASSETS

Under German GAAP, property, plant and equipment is recognized at acquisition or
manufacturing cost, as applicable, less accumulated depreciation and acquired
intangible fixed assets are recognized at acquisition cost less accumulated
amortisation. In practice, the useful live is based on schedules of asset useful
lives as provided by tax regulations. Moveable tangible assets can also be
depreciated using an accelerated depreciation method (declining balance).

U.S. GAAP requires that property, plant and equipment be carried at cost less
accumulated depreciation in accordance with the estimated economic useful life
of the asset. Accelerated depreciation methods can only be used if the actual
usage of the assets justifies that method. Intangible assets with a definite
useful life are

                                       25


amortized over their expected useful life. Intangible assets with an indefinite
useful life and goodwill are not amortized but reviewed for impairment at least
once a year.

IMPAIRMENTS FOR LONG-LIVED ASSETS

Under German GAAP, based on the modified lower of cost or market principle, any
permanent decline in value of tangible or intangible fixed assets results in an
impairment. An impairment loss recognized in prior years has to be reversed if
the reason for impairment no longer exists.

Under US GAAP a company is required to perform an impairment analysis on its
long-lived assets if certain indicators exist. In this analysis a two-step model
is used. For tangible long-lived assets and definite-lived intangible assets the
first step is a comparison of an asset's carrying amount with the sum of
undiscounted cash flows generated by the asset. An impairment is indicated only
if the undiscounted cash flows are less then the asset's carrying amount. If an
impairment is indicated through the first step, the impairment loss is measured
in the second step as the difference between the asset's carrying value and its
fair value.

The impairment test for goodwill and indefinite-lived intangible assets requires
in step one to compare the fair value and carrying amount of a reporting unit
including goodwill. If the fair value of the reporting unit is less than its
book value, goodwill or the indefinite-lived intangible asset is considered to
be impaired. In step two, the impairment amount is measured as the excess of the
assets carrying amount over its implied fair value (i.e., fair value of the
reporting unit minus fair value of individual identifiable assets and
liabilities). U.S. GAAP does not allow the reversal of previously recorded
impairment losses.

INVENTORIES

German GAAP requires inventories to be valued at lower of cost or market. Market
value is usually defined as net realizable value or replacement cost. Further
write-downs may be made to the extent that they are necessary based on sound
business judgment to avoid valuation to change in the near future.

Under US GAAP inventories are valued at lower of cost or market. Market is
defined as current replacement cost, except that market should not exceed net
realizable value and it should not be less than the net realizable value reduced
by an allowance for an approximately normal profit margin.

MEASUREMENT OF FOREIGN CURRENCY RECEIVABLES AND LIABILITIES

Under German GAAP, unrealised losses with respect to foreign currency
receivables and liabilities are recognised in earnings, while unrealised gains
are deferred until the underlying asset or liability is settled.

Under U.S. GAAP receivables and liabilities denominated in foreign currencies
are translated at the balance sheet date rate and any unrealised gains or losses
are recognised in the income statement.

SCOPE OF CONSOLIDATION

Under German GAAP, consolidation of all significant majority-owned subsidiaries
is required. Entities in which an equity interest is held and where the investor
actually exercises significant influence over the business and financial policy
(associated companies) are valued at equity, unless they are insignificant.

Under U.S. GAAP, the determination when an entity is to be consolidated has
traditionally been determined based on a voting control model. While this model
is still applicable, new FASB Interpretation No. 46, "Consolidation of Variable
Interest Entities" ("FIN 46") has broadened the scope of consolidation to
include a risk and rewards model. Variable interest entities ("VIE's"), which
often are special purposes entities, in which a parent does not have a
controlling voting interest but the parent absorbs the majority of the VIE's
expected losses or residual returns must also be consolidated. The equity method
is generally required for investments where the parent company has more than 20%
of the voting rights or if factors indicate that significant influence exists.
Furthermore, U.S. GAAP does not provide any exemption from consolidation or
equity accounting based on significance of the investment.

BUSINESS COMBINATIONS AND GOODWILL

Under German GAAP, business combinations will be generally accounted under the
purchase method. When purchase accounting is applied, goodwill arising on the
acquisition of an entity can be offset directly against reserves or capitalized
and amortized over the estimated economic useful life, generally over a period
of 7 to 15 business years. Any negative goodwill is recorded as part of the
reserves within equity. Business combinations are generally accounted on the
effective date as determined in the acquisition agreement. Consolidation for
acquisitions and de-consolidation for divestures may also be accounted as of the
beginning or ending of the respective period.

Under U.S. GAAP, for all business combinations initiated after July 1, 2001,
business combinations are accounted under the purchase method. Business
combinations are generally accounted for on the date of acquisition, which is
ordinarily the date assets are received and other assets are given, liabilities
are assumed or incurred, or equity interests are issued. Furthermore, all
separately identifiable tangible and intangible assets acquired and liabilities
assumed are recorded at fair value and the excess of the cost of an acquired
entity over the fair value of net assets acquired is allocated to goodwill.
Goodwill is not amortized, but, instead, is tested for impairment annually at
the reporting unit level, or more frequently based upon facts and circumstances.
The excess of fair value of acquired net assets over cost (negative goodwill)
must be allocated on a pro-rata basis to all non-current assets other than
financial assets, prepaid pension assets and deferred taxes. Any remaining
negative goodwill is recognized as an extraordinary gain.

PENSION PROVISIONS AND PROVISIONS FOR OTHER POSTRETIREMENT BENEFITS

Under German GAAP, pension obligations are determined using actuarial
principles, whereby the ongoing and future pension obligations and benefit
obligations to retired beneficiaries are determined using a valuation benchmark
in line with tax regulations. For other postretirement benefits the general
rules for provisions apply. Increases in future salary or pension costs are not
included in the calculation of the provisions.

Under U.S. GAAP, the annual pension cost comprises the estimated cost of
benefits accruing in the period as determined in accordance with SFAS 87,
"Employers' Accounting for Pensions" which requires readjustment of the
significant actuarial assumptions annually to reflect current market and
economic conditions. Under SFAS 87, a pension asset or liability representing
the excess or deficit of plan assets over benefit obligations is recognized in
the balance sheet. The pension benefit obligation is calculated by using a
projected unit credit method, including assumptions for future salary increases.
Actuarial gains or losses outside of a 10% "corridor" have to be amortized over
future periods as a component of net pension cost. Gains and losses inside the
corridor are generally not recognized. Specific guidance exists for other
postretirement benefits.

GUARANTEES

Under German GAAP, a guarantor records an accrual and a corresponding charge to
the income statement when an enterprise has a present obligation as a result of
a past event and it is expected, based on available evidence, that payment would
have to be made to the guaranteed party.

Under U.S. GAAP, a guarantor is required to recognize, at the inception of
certain guarantees, a liability for the fair value of the obligation undertaken
in issuing the guarantee irrespective of the probability of outflows of economic
benefits. Such guarantees generally include contracts that contingently require
the guarantor to make payments to the guaranteed party based on changes in an
underlying that is an asset, a liability or an equity security of the guaranteed
party, certain third party performance guarantees and indemnification clauses in
sale or purchase agreements.

OTHER PROVISIONS

Under German GAAP, provisions are set up for uncertain liabilities and for
potential losses from pending transactions. In addition provisions for
maintenance costs to be incurred within three months after year-end have to be
recorded. For maintenance costs to be incurred later than three months after
year-end and for other internal costs provisions may be set up, if they were
caused in the current or past periods.

                                       27


Under U.S. GAAP, a provision for a contingency is recorded when it is probable
and can be reasonably estimated. SFAS No. 5 uses the term probable to describe a
future event in which the outcome is likely to occur. Accordingly, under U.S.
GAAP, a higher recognition threshold is applied than under German GAAP.
Provisions for maintenance costs to be incurred and internal costs are not
allowed under U.S. GAAP.

ENVIRONMENTAL REMEDIATION LIABILITIES

Under German GAAP for environmental liabilities no specific guidance exists.
Provisions are valued based on best estimates; they may be discounted if the
underlying obligation contains an interest element even if the amount and timing
of the cash flows is not reliably determinable.

Under U.S. GAAP provisions for losses associated with environmental remediation
obligations are recorded when such losses are probable and reasonably estimable.
Specific guidance is available relating to the recognition and measurement of
environmental liabilities. Discounting environmental remediation liabilities is
only allowed if the aggregate amount of the obligation or components thereof and
the amount and timing of the cash payments are fixed or reliably determinable.

RESTRUCTURING COSTS

Under German GAAP, a provision for exit, disposal or other restructuring
activities is established if management decides to undertake restructuring
activities. Provisions are valued based on best estimates.

U.S. GAAP requires a liability for costs associated with an exit or disposal
activity to be recognised when the liability is incurred. This requires that a
detailed plan has been approved and communicated to the employees, significant
changes to the plan are unlikely to occur and the company has little or no
discretion to avoid payment. Under U.S. GAAP, if employees are not required to
render service until they are terminated in order to receive the termination
benefits, a liability for the termination benefits shall be recognized and
measured at its fair value at the communication date. If employees are required
to render service in order to receive the termination benefits the expense is
generally recognized over the future service period.

SPECIAL RESERVES

Under German GAAP gains on the sale of certain assets may be deferred and are
recognized in a special reserve. Such gains are recognized in income in
subsequent years based on the related depreciation expense of newly acquired
assets.

Under US GAAP gains on the sale of all assets are taken to income when they are
realized. Deferral of such gains is not permissible.

REVENUE RECOGNITION

German GAAP focuses on the transfer of economic ownership and the transfer of
the risk of loss when recognizing revenue. Revenue is generally recognized when
the goods are sold.

Under U.S. GAAP there are four key criteria that must be present in order to
recognize revenue under US GAAP. These four criteria are (a) the seller's price
to the buyer is fixed or determinable, (b) collectibility of payment is
reasonably assured, (c) there must be persuasive evidence that an arrangement
exists and (d) delivery must have occurred or services must be rendered.
Furthermore, U.S. GAAP provides specific accounting guidance regarding multiple
element arrangements.

                                       28


DEFERRED TAXES

Under German GAAP, deferred taxes are only recognised for transactions where the
expense or the income is recognised in different periods for tax and book
purposes (timing concept). Under German GAAP, deferred taxes are not recognized
for temporary differences that are not expected to reverse in the foreseeable
future, and for temporary differences that are expected to reverse during future
periods in which net operating losses are expected to be available to offset
income taxes that would otherwise be payable. In accordance with German GAAP,
Heinrich Industrie elected to only recognize deferred tax assets if they arose
during consolidation.

Under U.S. GAAP, deferred taxes are generally recognized for all temporary
differences. In addition, in contrast to German GAAP, U.S. GAAP requires the
recognition of deferred tax assets attributable to net operating loss
carryforwards. A valuation allowance is recorded against deferred tax assets to
the extent that it is more likely than not that the deferred tax asset will not
be realized.
