                   LINDSAY MANUFACTURING CO. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

(1) GENERAL

The consolidated financial statements included herein are presented in
accordance with the requirements of Form 10-Q and consequently do not include
all of the disclosures normally required by accounting principles generally
accepted in the United States of America for annual reporting purposes or those
made in the Company's annual Form 10-K filing. These consolidated financial
statements should be read in conjunction with the consolidated financial
statements and notes thereto included in the Lindsay Manufacturing Co. (the
"Company" or "Lindsay") Form 10-K for fiscal 2002.

         In the opinion of management, the unaudited consolidated financial
statements of the Company reflect all adjustments of a normal recurring nature
necessary to present a fair statement of the financial position and the results
of operations and cash flows for the respective interim periods. The results for
interim periods are not necessarily indicative of trends or results expected for
a full year. Certain reclassifications have been made to prior financial
statements and notes to conform to the current presentation.

         Notes to the consolidated financial statements describe various
elements of the financial statements and the assumptions on which specific
amounts were determined. While actual results could differ from those estimated
at the time of preparation of the consolidated financial statements, management
is committed to preparing financial statements, which incorporate accounting
policies, assumptions, and estimates that promote the representational
faithfulness, verifiability, neutrality, and transparency of the accounting
information included in the consolidated financial statements.

(2) CASH EQUIVALENTS, MARKETABLE SECURITIES AND LONG-TERM MARKETABLE SECURITIES

Cash equivalents are included at cost, which approximates market. At February
28, 2003, the Company's cash equivalents were held primarily by one financial
institution. Marketable securities and long-term marketable securities are
categorized as held-to-maturity as management of the Company has determined that
it has the intent and ability to hold these securities to maturity. Held to
maturity securities are carried at amortized cost. The Company considers all
liquid investments with maturities of three months or less to be cash
equivalents, while those having maturities in excess of three months are
classified as marketable securities or as long-term marketable securities when
maturities are in excess of one year. The Company's marketable securities and
long-term marketable securities consist of investment-grade municipal bonds.

         The total amortized cost, gross unrealized holding gains, gross
unrealized holding losses, and aggregate fair value for held-to-maturity
securities at February 28, 2003, were $35.8 million, $717,000, $6,000 and $36.5
million, respectively. Marketable securities with an amortized cost of $8.0
million mature within one year and long term marketable securities with an
amortized cost of $27.8 million have maturities ranging from 14 to 41 months.

         The total amortized cost, gross unrealized holding gains, gross
unrealized holding losses, and aggregate fair value for held-to-maturity
securities at February 28, 2002 were $34.3 million, $550,000, $22,000 and $34.8
million, respectively. Marketable securities with an amortized cost of $9.9
million mature within one year and long term marketable securities with an
amortized cost of $24.4 million have maturities ranging from 15 to 40 months.

(3) INVENTORIES

Inventories are stated at the lower of cost or market. Cost is determined by the
last-in, first-out (LIFO) method for most inventories. Cost is determined by the
weighted average method for inventories at the Company's foreign subsidiaries
and at the Company's dealership subsidiary, Irrigation Specialists. The Company
reserves for obsolete, slow moving and excess inventory by estimating the net
realizable value based on the potential future use of such inventory.

(5) CREDIT ARRANGEMENTS

The Company may borrow up to $10.0 million under an unsecured revolving line of
credit agreement with a commercial bank. Borrowings under this line of credit,
if any, are to be used for working capital and general corporate purposes
including stock repurchases. At February 28, 2003 and 2002, the Company has not
borrowed any proceeds from this line. Borrowings will bear interest at an annual
rate equal to 1% under the bank's National Base Rate in effect from time to time
(4.25% at February 28, 2003); provided that the National Base Rate will not be
less than 4.00%. The revolving line of credit agreement expires on December 28,
2003 at which time the Company expects to renew the line of credit on
substantially similar terms.

(6) NET EARNINGS PER SHARE

Basic net earnings per share is computed by dividing net earnings by the
weighted average number of shares outstanding. Diluted net earnings per share
includes the dilutive effect of stock options.

         At February 28, 2003, options to purchase 196,062 shares of common
stock at a weighted average price of $25.89 per share were outstanding, but were
not included in the computation of diluted EPS because the options' exercise
price was greater than the average market price of the common shares. These
options expire between September 3, 2007 and May 3, 2012.

         At February 28, 2002, options to purchase 89,625 shares of common stock
at a weighted average price of $27.59 per share were outstanding, but were not
included in the computation of diluted EPS because the options' exercise price
was greater than the average market price of the common shares. These options
expire between September 3, 2007 and September 3, 2008.

(7) INDUSTRY SEGMENT INFORMATION

The Company manages its business activities in two reportable segments:

     Irrigation: This segment includes the manufacture and marketing of center
     pivot, lateral move and hose reel irrigation systems and related control
     and ancillary equipment.

     Diversified Products: This segment includes providing outsource
     manufacturing services and the manufacturing and selling of large diameter
     steel tubing.

     The accounting policies of the two reportable segments are the same as
those described in the "Accounting Policies" in Note A. of the financial
statements included in the Form 10-K for the fiscal year ended August 31, 2002.
The Company evaluates the performance of its operating segments based on segment
sales, gross profit and operating income, with operating income for segment
purposes excluding general and administrative expenses (which include corporate
expenses), engineering and research expenses, interest income net, other income
and expenses net, income taxes, and assets. Operating income for segment
purposes does include selling expenses and other overhead costs directly
attributable to the segment. There are no intersegment sales.

The cash surrender value of life insurance policies reflects cumulative cash
surrender value generated primarily by payment of life insurance premiums
between 1993 and 2000 and appreciation during and since that period. Prior to
fiscal 2003, the Company had not recorded the increase in the cash surrender
value of the policies. The change in the cash surrender value of these life
insurance policies was not material to the Company's net earnings for any prior
period reported. The Company anticipates future, normal changes in the cash
value of these policies will also not be material.

(10) GUARANTEES

The Company is currently party to various guarantee arrangements. These
agreements arose in transactions related to dealer/customer financing, the
guarantee of debt for an equity investment and product warranties.

         The Company has adopted FASB Interpretation No. 45, Guarantor's
Accounting and Disclosure Requirements for Guarantees, Including Indirect
Guarantees of Indebtedness of Other (the "Interpretation"). The Interpretation
requires a guarantor to recognize a liability for the non-contingent component
of the guarantee, this is the obligation to stand ready to perform in the event
that specified triggering events or conditions occur. The initial measurement of
this liability is the fair value of the guarantee at inception. The recognition
of the liability is required even if it is not probable that any payments will
be required under the guarantee or if the guarantee has premium payments or as
part of a transaction with multiple events. The Company has adopted the
disclosure requirements of the Interpretation and will apply the recognition and
measurement provisions for all guarantees entered into or modified after
December 31, 2002 when those guarantees are estimable. The following table
provides the maximum amount of potential future payments for each major group of
guarantees:

GUARANTEES ON THIRD PARTY DEBT OF EQUITY INVESTMENT

The Company holds a minority investment in an irrigation dealership that is
accounted for on the equity method. The dealership has bank notes outstanding
for which the general assets of the dealership have been pledged as collateral.
To enhance the credit standing of the dealership, the Company has guaranteed a
portion of the principal value of the bank notes. Additionally, the majority
owner of the dealership has guaranteed a portion of the principal value of the
bank notes. One of the bank notes matures in December 2006, while the other bank
notes originally matured on December 31, 2002, but were extended to March 2003
and have subsequently been refinanced. The total guarantee by the Company
granted on the dealership bank notes was $502,000 on February 28, 2003. Separate
but related to this dealership, the Company has provided a standby letter of
credit, which expires in December 2003, for $169,000 to enhance the credit
standing of the majority owner of the dealership.

CUSTOMER EQUIPMENT FINANCING RECOURSE

In the normal course of business, the Company has arranged for unaffiliated
financial institutions to make favorable financing terms available to end-user
purchasers of the Company's irrigation equipment. In order to facilitate these
arrangements, the Company provided the financial institutions with limited
recourse guarantees or full guarantees, as more fully described below.

         The Company maintains an agreement with a single financial institution
that guarantees the financial institution's related portfolio limited to $1.4
million as of February 28, 2003. Generally, the Company's exposure is limited to
unpaid interest and principal where the first and/or second annual customer
payments have not yet been made as scheduled. The maximum exposure is generally
representative of 2.75% of the original loan amount financed or the total
equipment cost related to a lease. Related to this exposure amount, the Company
has accrued $356,000 within the allowance for doubtful accounts as of February
28, 2003. The amount accrued is based, in large part, on the Company's
experience with this agreement and related transactions.

         Separately, the Company maintains limited customer financing recourse
agreements with three financial institutions including the one referred to
above. Generally, the Company's exposure is limited to unpaid interest and
principal where the first and/or second annual customer payments have not yet
been made as scheduled. In some specific cases, the guarantee may cover up to
all scheduled payments of a loan. The original amount of existing guarantees is
approximately $1.5 million at February 28, 2003. The Company's recourse
guarantee is collateralized by the value of the equipment. No liability has been
accrued for the value of the limited customer guarantees.

PRODUCT WARRANTIES

The Company generally warrants its products against certain manufacturing and
other defects. These product warranties are provided for specific periods of
time and/or usage of the product. The Company had accrued liabilities of $1.2
million and $1.4 million as of February 28, 2003 and 2002, respectively,
relating to product warranty claims. The accrued product warranty costs are for
a combination of specifically identified items and other unidentified items
based primarily on historical experience of actual warranty claims. Warranty
claims expense were $215,000 and $226,000 for the three month period ended
February 28, 2003 and 2002, respectively, and $609,000 and $552,000 for the six
month period ended February 28, 2003 and 2002, respectively. The following table

In preparing the consolidated financial statements in conformity with accounting
principles generally accepted in the United States of America, management must
make a variety of decisions, which impact the reported amounts and the related
disclosures. These decisions include the selection of the appropriate accounting
principles to be applied and the assumptions on which to base accounting
estimates. In making these decisions, management applies its judgment based on
its understanding and analysis of the relevant circumstances and the Company's
historical experience. The Company's significant accounting policies are
described in Note A to the Consolidated Financial Statements in the Company's
Form 10-K for fiscal 2002.

         Certain of the Company's accounting policies have been deemed by
management to be critical because of their overall importance to the
presentation of the Company's consolidated results of operations and financial
condition or because they require the greatest use of judgments and estimates by
management. The following accounting policies are those management considers
critical to the Company's consolidated results of operations and financial
condition. Management periodically re-evaluates and adjusts the estimates that
are used as circumstances change. There were no significant changes in critical
accounting policies during the six-months ended February 28, 2003.

         REVENUE RECOGNITION

         Revenues from the sale of the Company's products to its dealers or
customers are generally recognized upon the delivery of the product to the
Company's dealers or customers. The Company recognizes revenue of certain low
volume products only upon the earlier of the date a product is delivered by the
dealer to an end-user customer or the date the dealer makes payment on the sale
to the Company. The costs related to revenues, including the allowance for
doubtful accounts, are recognized in the same period in which the specific
revenues are recognized. Estimates used in the Company's revenue recognition and
cost recognition process include, but are not limited to, estimates for rebates
payable, cash discounts expected to be allowed, and the allowance for doubtful
or uncollectible accounts. The Company does not record any revenue that is
contingent or that is dependent upon future performance.

         INVENTORIES

         Inventories are stated at the lower of cost or market. Cost is
determined by the last-in, first-out (LIFO) method for most inventories. Cost is
determined by the weighted average method for inventories at the Company's
foreign subsidiary in France and at the Company's dealership subsidiary
Irrigation Specialists. The Company reserves for obsolete, slow moving and
excess inventory by estimating the net realizable value based on the potential
future use of such inventory.

COMPARISON OF THE THREE-MONTHS ENDED FEBRUARY 28, 2003 AND 2002

Operating revenues for the three-months ended February 28, 2003 were $48.1
million as compared to $40.7 million for the same prior year period.
Acquisitions and new business operations contributed $5.6 million in revenues
for the three-months ended February 28, 2003. Irrigation equipment revenues
totaled $45.4 million as compared to $37.0 million for the same prior year
period. Revenues increased primarily due to new operations. Additionally, new
products and firm agricultural commodity prices contributed modestly to the
increase in irrigation revenue. Diversified products revenues were $2.8 million
during the three-months ended February 28, 2003, lower than the same period
prior year revenues of $3.6 million. The decrease in diversified product
revenues was primarily due to contract manufacturing customers relying less on
outsourced manufacturing.

         Gross margin for the three-months ended February 28, 2003 was 25.5% as
compared to 24.8% for the same prior year period. The increase in gross margin
was primarily the result of modest price increases along with a continuation of
cost controls.

         Selling, general and administrative, and engineering and research
expenses during the three-months ended February 28, 2003 totaled $5.8 million as
compared to $4.7 million for the same prior year period. The increase was due to
primarily to incremental expenses related to new business operations established
after the three-months ended February 28, 2002. Excluding the new operations,
selling, general and administrative and engineering and research expenses
increased $247,000 over the same prior year period. Incremental engineering and
research expenses reflect new product initiatives.

         Other income during the three-months ended February 28, 2003 totaled
$242,000 as compared to other expense of $24,000 for the same prior year period.
Foreign currency gains were the primary cause of the increase in other income
compared to the same prior year period.



                                       12
<PAGE>

         The effective tax rate during the three-months ended February 28, 2003
was 30.3% as compared to 31.2% for the same prior year period. Overall, the
Company benefits from an effective tax rate which is lower than the combined
federal and state statutory rate primarily due to the federal income tax exempt
status of interest income from its municipal bond investments.

         Net earnings rose 25% to $5.0 million, or $0.42 per diluted share, for
the quarter ended February 28, 2003 compared with $4.0 million, or $0.33 per
diluted share, for the same prior year period.

COMPARISON OF THE SIX-MONTHS ENDED FEBRUARY 28, 2003 AND 2002

Operating revenues for the six-months ended February 28, 2003 were $81.6 million
as compared to $69.2 million for the same prior year period. Acquisitions and
new business operations contributed $8.5 million in revenues for the six-months
ended February 28, 2003. Irrigation equipment revenues totaled $76.0 million as
compared to $61.9 million for the same prior year period. Irrigation revenues
increased primarily due to new operations. Additionally, new products and firm
agricultural commodity prices contributed modestly to the increase in irrigation
revenue. Diversified products revenues were $5.6 million during the six-months
ended February 28, 2003, lower than the same prior period revenues of $7.3
million. The decrease in diversified product revenues was primarily due to
contract manufacturing customers relying less on outsourced manufacturing.

         Gross margin for the six-months ended February 28, 2003 was 23.6% as
compared to 22.7% for the same prior year period. The increase in gross margin
was primarily the result of modest price increases along with a continuation of
tighter cost controls.

         Selling, general and administrative, and engineering and research
expenses during the six-months ended February 28, 2003 totaled $11.6 million as
compared to $9.3 million for the same prior year period. The increase was due
primarily to incremental expenses related to new business operations established
after the six-months ended February 28, 2002. Excluding the new operations,
selling, general and administrative and engineering and research expenses
increased $709,000 over the same prior year period. Incremental engineering and
research expenses reflect new product initiatives.

         Other income during the six-months ended February 28, 2003 totaled $2.0
million as compared to $155,000 for the same prior year period. During the six
months ended February 28, 2003, the Company recorded both other income and other
non-current assets of $1.8 million to reflect the cumulative cash surrender
value of four life insurance policies that the Company maintains on current and
former executive officers; $1.7 million of which was reported during the first
fiscal quarter ended November 30, 2002.

         The effective tax rate during the six-months ended February 28, 2003
was 25.5% as compared to 31.0% for the same period of the prior year. The
principal reason for the significantly lower effective tax rate during the first
six-months of fiscal 2003 was the impact of the other income associated with the
cash surrender value of life insurance policies referred to above, all of which
is exempt from state and federal income taxes. Without the impact of this other
income, the Company's effective tax rate for the six months ended February 28,
2003 would have been 30.5%. Overall, the Company benefits from an effective tax
rate which is lower than the combined federal and state statutory rate primarily
due to the federal income tax exempt status of interest income from its
municipal bond investments.

         Excluding the impact of the other income associated with the cash
surrender value of life insurance policies discussed above, which amounted to
$0.15 per diluted share, net earnings rose 20% to $6.1 million, or $0.51 per
diluted share, for the first six-month period of fiscal 2003 compared with $5.1
million, or $0.43 per diluted share, in the first six-months of fiscal 2002.

OUTLOOK

Long term, the Company believes that the drivers for agricultural irrigation
equipment demand remain solidly in place; farmers need to conserve water, energy
and labor while at the same time improve and stabilize crop yields and increase
food production for a growing world population. The Company's order backlog at
February 28, 2003, grew to $20.4 million compared with $17.4 million at February
28, 2002, and $18.9 million at August 31, 2002. Management believes the Company
will continue to realize growth in total revenues during the second half of
fiscal 2003. The growth expectations have been somewhat dampened by current
economic and geopolitical factors which will likely constrain total industry
growth for the remainder of the fiscal year; however, it is expected the Company
will continue to achieve revenue and earnings growth through new products,
expanded parts sales initiatives and geographical expansion. Additionally, the
Company has been managing a search process to seek business extensions through
acquisitions that are congruent with its mission to be the worldwide leader in
providing intelligent water and plant nutrient management systems, while adding
incremental value for shareholders.

LIQUIDITY AND CAPITAL RESOURCES

The Company requires cash for financing its receivables, inventories, any
acquisitions, capital expenditures, any stock repurchases and dividends.
Historically, the Company has financed its growth through funds provided by
operations. In addition, the Company maintains a $10.0 million bank line of
credit. The Company has not borrowed any funds under this line of credit and the
entire $10.0 million is available to the Company. Management believes that funds
provided by operations, supplemented if necessary by borrowings under the line
of credit, will be sufficient to cover reasonably expected working capital needs
of the Company, including the payment of dividends, and any planned capital
expenditures during fiscal 2003. As of February 28, 2003, the Company held cash
and marketable securities of $41.2 million as compared to $41.9 million as of
the same prior year period. Although the Company's marketable securities could
be readily converted into cash if needed, the Company intends to hold these as
investments until maturity, and does not anticipate that the sale of any of its
marketable securities will be necessary to meet its reasonably foreseeable cash
requirements. Remaining maturities of these securities range from 4 to 41
months.

         During the six months ended February 28, 2003, the Company's net cash
position decreased from $12.4 million to $5.4 million. The decrease in the net
cash position was a result of cash provided by operating activities of $7.7
million, cash provided by investing activities of $1.5 million and cash used in
financing activities of $798,000 during the period.

         The Company used cash in operating activities primarily to finance an
increase in receivables and inventories, which was offset by the Company's net
earnings and an increase in payables. Receivables increased $13.3 million from
the level of August 31, 2002 primarily due to new business operations
established after February 28, 2002 and the seasonality of sales including the
Company's dealer stock program. Inventories at February 28, 2003 increased $5.8
million as compared to August 31, 2002 primarily due to new business operations
established after February 28, 2002 and seasonal production scheduling. Accounts
payable increased $3.9 million primarily due to the timing of production
materials purchases and new business operations established after February 28,
2002.

         During the first six months of fiscal 2003, the Company used cash in
investing activities in order to purchase $6.1 million of additional marketable
securities and to make capital expenditures of $1.6 million. The capital
expenditures were used primarily to upgrade and further automate the Company's
manufacturing facilities. The Company expects that total capital expenditures
for fiscal 2003 will be approximately $3.0 to $3.5 million and that they will be
made to improve the Company's manufacturing facilities. These uses of cash were
offset during the period by $9.2 million of proceeds from maturing marketable
securities.

         Approximately $798,000 of cash was used in financing activities during
the six-months ended February 28, 2003. This net use of cash was primarily for
the payment of dividends on the Company's common stock.

         The Company's equity increased to $98.0 million at February 28, 2003
from $90.7 million at August 31, 2002 due primarily to its net earnings of $7.8
million and accumulated other comprehensive income of $270,000 less dividends
paid of $821,000. The Company's equity at February 28, 2002 was $85.6 million.

SEASONALITY

Irrigation equipment sales are seasonal by nature. Farmers generally order
systems to be delivered and installed before the growing season. Shipments to U.
S. customers usually peak during the Company's second and third quarters for the
spring planting period.

CUSTOMERS

Management believes that overall the Company is not dependent on a single
customer. The diversified manufacturing segment, however, is largely dependent
on a few customers. While the loss of any substantial customer could have a
meaningful short-term impact on the Company's business, the Company believes
that its diverse distribution channels and customer base reduces the long-term
impact of any such loss.

OTHER FACTORS

The Company's irrigation equipment sales are highly dependent upon the need for
irrigated agricultural production, which, in turn, depends upon many factors
including total worldwide crop production, the profitability of agricultural
production, agricultural commodity prices, aggregate net cash farm income,
governmental policies regarding the agricultural sector, water and energy
conservation policies and the regularity of rainfall. In addition, irrigation
equipment sales are affected by the Company's ability to develop new products
and the market acceptance of these products, expenditures on advertising and
other promotions, competition from other manufacturers of these products;
changes in our distributors' or dealers' purchasing practices and financial
viability.

         Approximately 20% and 15% of the Company's operating revenues for the
three-months ended February 28, 2003 and 2002 were generated from international
irrigation sales. Factors that affect the Company's international irrigation
sales include, economic, political and social conditions in individual
international markets; the value of the U.S. dollar against the foreign
currencies, especially the Euro, Brazilian real, Australian dollar, Canadian
dollar, South African rand and Mexican peso; heightened security for import and
export shipments of goods and changes in tariffs, import duties and other taxes.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In November 2002, the Financial Accounting Standards Board ("FASB") issued
Interpretation No. 45, Guarantor's Accounting and Disclosure Requirements for
Guarantees, Including Indirect Guarantees of Indebtedness of Others (the
Interpretation), which addresses the disclosure to be made by a guarantor in its
interim and annual financial statements about its obligations under guarantees.
These disclosure requirements are included in Note 10 to the consolidated
financial statements. The Interpretation also requires the recognition of a
liability by a guarantor at the inception of certain guarantees.

         The Interpretation requires the guarantor to recognize a liability for
the non-contingent component of the guarantee, this is the obligation to stand
ready to perform in the event that specified triggering events or conditions
occur. The initial measurement of this liability is the fair value of the
guarantee at inception. The recognition of the liability is required even if it
is not probable that payment will be required under the guarantee or if the
guarantee was issued with premium payments or as part of a transaction with
multiple events.

         As noted above, the Company has adopted the disclosure requirements of
the Interpretation (see Note 10) and will apply the recognition and measurement
provisions for all guarantees entered into or modified after December 31, 2002.

         In October 2001, the FASB issued Statement of Financial Accounting
Standards ("SFAS") No. 144 "Accounting for the Impairment or Disposal of
Long-Lived Assets", replacing SFAS No. 121 "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of". The adoption of
SFAS No. 144 has not had a material impact on the Company's consolidated
financial statements.

         In July 2001, the FASB issued SFAS No. 141, "Business Combinations" and
SFAS No. 142, "Goodwill and Other Intangible Assets". SFAS No. 141 requires that
the purchase method of accounting be used for all business combinations
initiated after June 30, 2001, and eliminates the use of the
pooling-of-interests method. SFAS No. 141 also provides new criteria to
determine whether an acquired intangible asset should be recognized separately
from goodwill. SFAS No. 142 requires that goodwill and intangible assets with
indefinite useful lives no longer be amortized but instead tested for impairment
at least annually at the reporting unit level using a two-step impairment test.
The Company has adopted the provisions of SFAS No. 142 during the first quarter
of fiscal 2003, as required, and accordingly no longer amortizes any goodwill.
The adoption of SFAS No. 142 has not had a material impact on the Company's
consolidated financial statements.

CONCERNING FORWARD-LOOKING STATEMENTS - This quarterly report on Form 10-Q
contains not only historical information, but also forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934. Statements that are not historical are
forward-looking and reflect expectations for future company performance. In
addition, forward-looking statements may be made orally or in press releases,
conferences, reports, on the Company's worldwide web site, or otherwise, in the
future by or on behalf of the Company. When used by or on behalf of the company,
the words "expect", "anticipate", "estimate", "believe", "intend", and similar
expressions generally identify forward-looking statements. For these statements,
the Company claims the protection of the safe harbor for forward-looking
statements contained in the Private Securities Litigation Reform Act of 1995.

         Forward-looking statements involve risks and uncertainties. These
uncertainties include factors that affect all businesses operating in a global
market, as well as matters specific to the Company and the markets it serves.
Particular risks and uncertainties that could affect the Company's overall
financial position include the continuing slowdown in the global and domestic
economy that began in 2000; additional economic uncertainty created by the war
in Iraq and threat of continued terrorist acts, both of which could further
reduce growth in the U.S. and worldwide economy; the effect of the economic
slowdown on the Company's customers' ability to pay amounts owed to the Company;
weather conditions affecting demand, including warm winters and wet or cold
spring and dry summer weather; inability to raise prices of products due to
market conditions; changes in market demographics; actions of competitors;
inability to achieve earnings growth in fiscal 2003; increased insurance costs;
the Company's ability to develop and manufacture new and existing products based
on anticipated investments in manufacturing capacity and engineering; market
acceptance of existing and new products relative to expectations and based on
current commitments to fund advertising and promotions; increased competition in
the Company's businesses; financial viability of some distributors and dealers;
the Company's ability to acquire, develop, and integrate new businesses and
manage alliances successfully; changes in distributor and dealer ownership and
purchasing practices; the Company's ability to cost-effectively expand existing,
open new, move production between, and close manufacturing facilities; the
Company's ability to manage costs and capacity constraints at its manufacturing
facilities; the Company's ability to cost-effectively eliminate any
non-performing product lines; the Company's ability to manage inventory levels
and fully realize recorded inventory value; the impact of unexpected trends in
warranty claims or unknown product defects; the ability to hire, retain and
maintain good relationships with quality employees; threatened or pending
litigation action relating to patent infringement, employment, commercial
disputes and other matters; government action, including budget levels,
regulation, and legislation, primarily legislation relating to the environment,
commerce, infrastructure spending, health, and safety; availability of raw
materials and unforeseen price fluctuations for commodity raw materials; and the
impact of new accounting standards.

         Particular risks and uncertainties facing the Company's international
business at the present include weak economic conditions in global markets;
political and social conditions in individual international markets; the value
of the U.S. dollar against foreign currencies, especially the Euro, Brazilian
real, Australian dollar, Canadian dollar, South African rand and Mexican peso;
heightened security for import and export shipments of goods and changes in
tariffs, import duties and other taxes.

         Readers are cautioned not to place undue reliance on any
forward-looking statement and to recognize that the statements are predictions
of future results, which may not occur as anticipated. Actual results could
differ materially from those anticipated in the forward-looking statements and
from historical results, due to the risks and uncertainties described above, as
well as others not now anticipated. The foregoing statements are not exclusive
and further information concerning the Company and its businesses, including
factors that potentially could materially affect the Company's financial
results, may emerge from time to time. The Company assumes no obligation to
update forward-looking statements to reflect actual results or changes in
factors or assumptions affecting such forward-looking statements.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The market value of the Company's marketable securities will fluctuate inversely
with movements in interest rates. However, the Company does not consider itself
to be subject to material market risks with respect to its marketable securities
because of the relatively short remaining maturities (4 to 41 months) of the
securities held by the Company and because the Company intends to hold the
investments in these marketable securities to maturity and has the ability to do
so.

         The Company has manufacturing operations in the United States, France,
Brazil and South Africa. The Company sells products in over 90 countries
throughout the world and purchases a portion of its components from third-party
foreign suppliers. Export sales made from the United States are principally U.S.
dollar denominated. Accordingly, these sales are not subject to significant
currency translation risk. However, a majority of the Company's revenue
generated from operations outside the United States is denominated in the
currency of the customer location. The Company's most significant transactional
foreign currency exposures are the Euro and the Brazilian real in relation to
the U.S. dollar. Fluctuations in the value of foreign currencies create
exposures, which can adversely affect the Company's results of operations. The
Company attempts to manage its transactional foreign exchange exposure by
monitoring foreign currency cash flow forecasts and commitments arising from the
settlement of receivables and payables, and from future purchases and sales.

         The Company's translation exposure resulting from translating the
financial statements of foreign subsidiaries into U.S. dollars is not hedged.
The most significant translation exposures are the Euro and the Brazilian real
in relation to the U.S. dollar.

ITEM 4 - CONTROLS AND PROCEDURES

A review and evaluation was performed by the Company's management, including the
Company's Chief Executive Officer (the "CEO") and Chief Financial Officer (the
"CFO"), of the effectiveness of the design and operation of the Company's
disclosure controls and procedures (as defined in Rule 13a-14 under the
Securities Exchange Act of 1934) as of a date within 90 days prior to the filing
of this quarterly report. Based on that review and evaluation, the CEO and CFO
have concluded that the Company's current disclosure controls and procedures, as
designed and implemented, were effective to ensure that information the Company
is required to disclose in this quarterly report is recorded, processed,
summarized and reported in the time period required by the rules of the
Securities and Exchange Commission. There have been no significant changes in
the Company's internal controls or in other factors that could significantly
affect these controls subsequent to the date of their evaluation. There were no
significant material weaknesses identified in the course of such review and
evaluation and, therefore, no corrective measures were taken by the Company.

                       registrant's ability to record, process, summarize and
                       report financial data and have identified for the
