                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

(1) CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The consolidated financial statements are presented in accordance with the
requirements of Form 10-Q and do not include all of the disclosures normally
required by accounting principles generally accepted in the United States of
America for financial statements contained in Lindsay Manufacturing Co.'s (the
"Company") annual Form 10-K filing. Accordingly, these condensed consolidated
financial statements should be read in conjunction with the consolidated
financial statements and notes thereto included in the Company's most recent
Form 10-K for the fiscal year ended August 31, 2004.

      In the opinion of management, the 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 by the
Company for a full year.

      Notes to the consolidated financial statements describe various elements
of the financial statements and the accounting policies, estimates, and
assumptions applied by management. While actual results could differ from those
estimated by management in the preparation of the consolidated financial
statements, management believes that the accounting policies, assumptions, and
estimates applied promote the representational faithfulness, verifiability,
neutrality, and transparency of the accounting information included in the
consolidated financial statements.

(2) STOCK BASED COMPENSATION

The Company maintains a stock option plan and accounts for this plan under the
recognition and measurement principles of APB Opinion No. 25, "Accounting for
Stock Issued to Employees". Net earnings does not reflect stock-based employee
compensation cost as all options granted under this plan had an exercise price
equal to the market value of the underlying common stock on the date of grant.
The following table illustrates the effect on net income and earnings per share
if the Company had applied the fair value recognition provisions of SFAS No.
123, "Accounting for Stock-Based Compensation", to stock-based employee
compensation.

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

Cash equivalents are included at cost, which approximates market. At November
30, 2004, primarily one financial institution held the Company's cash
equivalents. The Company considers all highly liquid investments with original
maturities of three months or less to be cash equivalents, while those having
original 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. Marketable securities and long-term marketable securities consist
of investment-grade municipal bonds.

      At the date of acquisition of an investment security, management
designates the security as belonging to a trading portfolio, an
available-for-sale portfolio, or a held-to-maturity portfolio. Following
management's fiscal year 2004 decision to transfer debt securities from the
held-to-maturity portfolio, the Company will not designate purchases to the
held-to-maturity portfolio for a period of at least two years. Currently, the
Company holds no securities designated as held-to-maturity or trading. All
investment securities are classified as available-for-sale and carried at fair
value. Unrealized appreciation or depreciation in the fair value of
available-for-sale securities is reported in accumulated other comprehensive
income, net of related income tax effects. The Company monitors its investment
portfolio for any decline in fair value that is other-than-temporary and records
any such impairment as an impairment loss. No impairment losses for
other-than-temporary declines in fair value have been recorded in the three
months ended November 30, 2004 and 2003. In the opinion of management, the
Company is not subject to material market risks with respect to its portfolio of
investment securities because the investment grade quality of the securities and
the maturities of these securities are relatively short, making their value less
susceptible to interest rate fluctuations.

Gross realized gains and losses from sale of available-for-sale securities were
a $5,000 gain and $51,000 loss, respectively, for the three-months ended
November 30, 2004 and $0 for the three-months ended November 30, 2003.

Amortized cost and fair value of investments in marketable securities classified
as held-to-maturity or available-for-sale according to management's intent are
summarized as follows:

(4) INVENTORIES

Inventories are stated at the lower of cost or market value. Cost is determined
by the last-in, first-out (LIFO) method for the Company's Lindsay, Nebraska
inventory. Cost is determined by the weighted average method for inventories at
the Company's other operating locations in Washington State, France, Brazil, and
South Africa. At all locations, the Company establishes reserves for obsolete,
slow moving, and excess inventory by estimating the net realizable value based
on the potential future use of such inventory.

(6)  CREDIT ARRANGEMENTS

The Company has an agreement with a commercial bank for a $10.0 million
unsecured revolving line of credit through December 28, 2005. Proceeds from this
line of credit, if any, are to be used for working capital and general corporate
purposes including stock repurchases. There have been no borrowings made under
such unsecured revolving line of credit. Under the terms of the line of credit,
borrowings, if any, bear interest at a rate equal to one percent per annum under
the rate in effect from time to time and designated by the commercial bank as
its National Base Rate (5.00% at November 30, 2004). The Company expects to
renew this line of credit on substantially similar terms.

      The Company's European subsidiary, Lindsay Europe, has an unsecured
revolving line of credit with a commercial bank under which it could borrow up
to the Euro equivalent of $2.7 million for working capital purposes. As of
November 30, 2004, there was a $782,000 outstanding balance on this line. Under
the terms of the line of credit, borrowings, if any, bear interest at a floating
rate in effect from time to time designated by the commercial bank as LIBOR+200
basis points. (4.65% at November 30, 2004).

(7)  NET EARNINGS PER SHARE

Basic net earnings per share is computed by dividing net earnings by the
weighted average number of shares outstanding during the period. Diluted net
earnings per share includes the incremental dilutive effect of stock options,
which have an exercise price below the average market price of the Company's
common shares during the period.

      The Company had additional stock options outstanding during the period,
but these options were excluded from the calculation of diluted earnings per
share because they had an exercise price exceeding the average market price of
the Company's common shares during the period, as set forth in the following
table:

(8) 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. The irrigation segment
consists of six operating segments that have similar economic characteristics
and meet the aggregation criteria of SFAS No. 131.

                                       9
<PAGE>

      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 to the consolidated
financial statements contained in the Company's 10-K for the fiscal year ended
August 31, 2004. 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, and net income taxes, and assets. Operating
income for segment purposes does include selling expenses and other overhead
charges directly attributable to the segment. There are no inter-segment sales.
Because the Company utilizes common operating assets for its irrigation and
diversified segments, it is not practical to separately identify assets by
reportable segment. Similarly, other segment reporting proscribed by FAS 131 is
not shown as this information cannot be reasonably disaggregated by segment and
is not utilized by the Company's management.

      The Company has no single customer representing 10% or more of its total
revenues during the three-months ended November 30, 2004 or 2003.

Summarized financial information concerning the Company's reportable segments is

Goodwill represents the excess of the allocable purchase price for assets
acquired in certain business acquisitions over the fair value of these assets at
the time of the acquisitions. Other intangible assets include non-compete
agreements, tradenames, patents, and plans and specifications. Goodwill and
intangible assets with indefinite useful lives are not amortized, but instead
are tested for impairment of their values at least annually in accordance with
SFAS No. 142, "Goodwill and Other Intangible Assets." The estimated fair value
of these assets depends on a number of assumptions including forecasted sales
growth and operating expenses of the reporting segment in which the assets are
used. To the extent that the relevant reporting unit is unable to achieve these
assumptions, impairment losses may be recognized. The Company completed its
annual impairment evaluation of these assets at August 31, 2004 and determined
that no impairment losses were indicated. Other intangible assets that have
finite lives are amortized over their realizable lives. During the first quarter
of fiscal year 2005, the Company capitalized costs of $279,000 for software
rights purchased from a development company, which will be marketed to
customers. The amortization method for this software is the greater of the ratio
of current sales to forecasted sales or a 3-year straight-line method.
Amortization expense for other intangible assets was $39,000 and $42,000 for the
three-months ended November 30, 2004 and 2003, respectively. The following table
summarizes the Company's other intangible assets:

CUSTOMER EQUIPMENT FINANCING

In the normal course of its 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 described below. The Company recorded,
at estimated fair value, deferred revenue of $70,000 at November 30, 2004,
compared to $78,000 at November 30, 2003 and $83,000 at August 31, 2004,
classified with other current liabilities, for guarantees. The estimated fair
values of these guarantees are based, in large part, on the Company's experience
with this agreement and related transactions. The Company recognizes the revenue
for the estimated fair value of the guarantees ratably over the term of the
guarantee. Separately, related to these exposures, the Company has accrued a
liability of $339,000, $302,000, and $290,000 at November 30, 2004 and 2003 and
August 31, 2004, respectively, also classified with other current liabilities,
for estimated losses on such guarantees.

      The Company maintains an agreement with a single financial institution
that guarantees the financial institution's pool of financing agreements with
end users. This guarantee is approximately $1.7 million as November 30, 2004 and
2003 and August 31, 2004. 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 of these limited
recourse guarantees is equal to 2.75% of the aggregate amounts originally
financed.

      Separately, the Company maintains limited, specific customer financing
recourse arrangements with three financial institutions including the
institution referred to above. The original amount of these specific guarantees
is approximately $2.2 million at November 30, 2004 and 2003 and August 31, 2004.
Generally, the Company's exposure is limited to unpaid interest and principal
where customer payments have not yet been made as scheduled. In some cases, the
guarantee may cover all scheduled payments of a loan.

      All of the Company's customer-equipment recourse guarantees are
collateralized by the value of the equipment being financed.

GUARANTEES ON THIRD PARTY DEBT RELATED TO EQUITY INVESTMENT

The Company has guaranteed three bank loans and a standby letter of credit on
behalf of the irrigation dealership based in Kansas in which the Company
previously held a minority equity investment position. The guarantees continue
until the loans, including accrued interest and fees, have been paid in full.
The bank loans have been declared to be in default by the bank due to the
insolvency of the dealership. As of November 30, 2004, the maximum aggregate
amount associated with the guarantees and letter of credit was approximately
$250,000. The Company has recorded a current liability as of November 30, 2004
for $250,000 based upon its best estimate of expected aggregate liability
associated with the bank loan guarantees. The majority owner of the business
provides a separate personal guarantee of the bank notes, although the
likelihood of recovery from the majority owner guarantee is uncertain.

PRODUCT WARRANTIES

The Company generally warrants its products against certain manufacturing and
other defects. These product warranties are provided for specific periods and/or
usage of the product. The accrued product warranty costs are for a combination
of specifically identified items and other incurred, but not identified, items
based primarily on historical experience of actual warranty claims. This reserve
is classified with other current liabilities. The following table provides the

(12) RETIREMENT PLAN

The Company has a supplementary non-qualified, non-funded retirement plan for
six current and former executives. Plan benefits are based on the participant's
average total compensation during the three highest compensation years of

(13) COMMITMENTS AND CONTINGENCIES

In the ordinary course of its business operations, the Company is involved, from
time to time, in commercial litigation, employment disputes, administrative
proceedings, and other legal proceedings. These include a consent decree that
the Company entered in 1992 with the U.S. Environmental Protection Agency
concerning groundwater contamination at its Lindsay, Nebraska facility, which is
included as an EPA superfund site. Management does not believe that these
matters, individually or in the aggregate, are likely to have a material adverse
effect on the Company's consolidated financial condition, results of operations,
or cash flows.

      The Company holds a minority position in an irrigation dealership based
outside of the United States. The Company has an obligation to purchase the
remaining shares of this company for an amount of approximately $1.5 million by
August 31, 2005.

ITEM 2 - MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION

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 conditions or 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. The entire section entitled "Market
Conditions and Fiscal 2005 Outlook" should be considered 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 a number of risks and uncertainties,
including but not limited to those discussed in the "Risk Factors" section in
the Company's annual report on Form 10-K for the year ended August 31, 2004.
Readers should not place undue reliance on any forward-looking statement and
should recognize that the statements are predictions of future results or
conditions, which may not occur as anticipated. Actual results or conditions
could differ materially from those anticipated in the forward-looking statements
and from historical results, due to the risks and uncertainties described
herein, as well as others not now anticipated. The risks and uncertainties
described herein 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. Except as
required by law, 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.

ACCOUNTING POLICIES

In preparing the Company's 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 accounting policies that are most important to the
presentation of its results of operations and financial condition, and which
require the greatest use of judgments and estimates by management, are
designated as its critical accounting policies. These critical accounting
policies are described in Note A to the Consolidated Financial Statements in the
Company's Form 10-K for fiscal 2004. Management periodically re-evaluates and
adjusts its critical accounting policies as circumstances change. However, there
were no significant changes in the Company's critical accounting policies during
the three-months ended November 30, 2004.

INTERNAL CONTROLS OVER FINANCIAL REPORTING

Beginning in fiscal 2005, Section 404 of the Sarbanes-Oxley Act of 2002 requires
the Company to include in the annual report on Form 10-K a report on
management's assessment of the effectiveness of the Company's internal controls
over financial reporting and a statement that the Company's independent auditor
has issued an attestation report on management's assessment of the Company's
internal controls over financial reporting. The Company believes it is
progressing on the project plan generally as expected to meet this requirement,
and has not identified material weaknesses in internal controls over financial
reporting, to-date. There are no assurances however, that the Company will not
discover deficiencies in its internal controls as it implements new
documentation and testing procedures to comply with the new Section 404
reporting requirement. If the Company discovers deficiencies or is unable to
complete the work necessary to properly evaluate its internal controls over
financial reporting, there is a risk that management and or the Company's
independent auditor may not be able to conclude that the Company's internal
controls over financial reporting are effective.

FOR THE THREE-MONTHS ENDED NOVEMBER 30, 2004

REVENUES

Operating revenues for the three months ended November 30, 2004 rose 9 percent
to $39.8 million from $36.5 million for the year-ago period. This increase was
attributable to both irrigation and diversified products improvements.

      Domestic irrigation revenues declined $.4 million or 2 percent, from the
same prior year period. The decline in revenue was due to a slightly more than
20% decline in unit volume, which was offset by price increases implemented
primarily in the second half of fiscal 2004. The Company believes pricing
policies, equipment prices, and commodity prices all contributed to the decline
in unit volume. The Company implemented a change to its pricing policies during
the rapid steel cost increases of 2004 which reduced the protected price period
to 30 days. Domestic irrigation equipment prices are approximately 20% higher
than the same period last year while agriculture commodity prices have declined.

      International irrigation equipment revenues for the three months ended
November 30, 2004 increased $1.9 million or 19% over the same prior year period.
These revenues include both the export sales of equipment manufactured in the
United States and sales of the Company's manufacturing operations in France,
Brazil, and South Africa. Export shipments to Australia and New Zealand were
significantly above the same period last year. Exports to the Middle East
increased but remain at historically low levels. Europe and South Africa
revenues were up significantly, and include the revenues of Stettyn, the
irrigation manufacturing company acquired in South Africa during the fourth
quarter of fiscal 2004. South American revenues were lower due in part to the
lower agricultural commodity prices.

                                       16
<PAGE>

      Diversified manufacturing revenues for the three months ended November 30,
2004 of $4.4 million increased $1.8 million or 72% from the same prior year
period. Revenues in this segment depend to a large degree on orders from a
relatively small number of customers. However, a significant portion of the new
business in this segment is from industrial customers, which are outside the
traditional agricultural equipment base. This segment utilizes and leverages the
equipment in the Lindsay, Nebraska plant.

GROSS MARGIN

Gross margin declined to 16.5 percent from 20.1 percent a year ago. Gross
selling margins in the domestic market were near the prior-year levels; however,
they were negatively impacted by higher overhead allocations per unit due to
lower production levels and higher factory spending. While margins in foreign
facilities continued to improve, they remain lower than domestic irrigation.

OPERATING EXPENSES

Operating expenses rose 6 percent to $7.0 million from $6.6 million, due to
increases in insurance, audit and tax preparation costs, and incremental
operating expenses of Stettyn, the South African business acquired in the fourth
quarter of fiscal 2004. However, operating leverage continued to improve, with
operating expenses at 17.7 percent of revenue compared with 18.1 percent of
revenue in the fiscal 2004 period.

INTEREST INCOME, OTHER INCOME, AND TAXES

Net interest income during the three-months ended November 30, 2004 of $261,000
was comparable to $424,000 the same prior year period. This $163,000 decrease
reflects a reduction of interest income from securities and interest bearing
checking accounts and an increase in interest expense.

      Other income, net of $384,000 during the three-months ended November 30,
2004 reflects a decrease of $65,000 compared to other income, net of $449,000
for the same prior year period, primarily reflecting lower foreign currency net
gains compared to the same prior year period.

      The income tax provision for the three months ended November 30, 2004 was
reduced by adjustments identified during the period primarily related to the tax
effect of inter-company inventory profit eliminations and a change in the
extraterritorial income credit. The effective tax rate expected for fiscal 2005
is 33.15% compared with 32.5% for fiscal 2004. This higher rate is due to higher
expected operating income in relation to the tax-exempt interest income from the
Company's municipal bond investments. Overall, the Company benefits from a U.S.
effective tax rate which is lower than the combined federal and state statutory
rates primarily due to the federal tax-exempt interest income on this portfolio.

      The American Jobs Creation Act of 2004 (the Act) which was signed into law
on October 22, 2004 includes provisions which phase out the extraterritorial
income deduction over a two year period beginning January 1, 2005. The first
year phase out of 20% will impact the Company's tax rates for the eight months
of 2005, which are in the fiscal year. This phase out has been included in the
effective tax rate calculation.

      The Act also includes provisions for a one-time deduction for qualifying
repatriations of foreign earnings during fiscal 2005. The Company does not
intend to repatriate earnings of its foreign subsidiaries during fiscal 2005.

      The incentive for U.S. production activities included in the Act,
effective for fiscal years beginning after December 31, 2004, will not impact
the Company's tax rate in fiscal 2005.

LIQUIDITY AND CAPITAL RESOURCES

The Company requires cash for financing its receivables and inventories, paying
operating costs and capital expenditures, and for dividends. Historically, the
Company has met its liquidity needs and financed all capital expenditures
exclusively from its available cash and funds provided by operations.

                                       17
<PAGE>

      The Company's cash and marketable securities totaled $43.6 million at
November 30, 2004, $56.3 million at August 31, 2003, and $56.0 million at
November 30, 2003. The Company's marketable securities consist primarily of
tax-exempt high-grade municipal debt.

      Cash flows used in operations totaled $10.5 million during the
three-months ended November 30, 2004 compared to $5.8 million provided by
operations during the same prior year period. Cash flows used in operations
increased $4.7 million compared to the same prior year period primarily due to
higher inventory builds of $4.3 million, a $1.1 million higher change in
accounts payable, and a $918,000 decrease in net earnings offset partially by a
lower $2.1 million change in accounts receivable. The inventory change was
primarily due to unit sales volumes which were lower than planned and the
accounts receivable change was primarily due to timing of dealer programs.
Capital expenditures were $1.3 million during the three-months ended November
30, 2004 compared to $721,000 during the same prior year period. Capital
expenditures were used primarily for updating manufacturing plant and equipment,
expanding manufacturing capacity, and further automating the Company's
facilities. Capital expenditures for fiscal 2005 are expected to be
approximately $4 to $5 million and will be used to improve the Company's
facilities and expand its manufacturing capacity. The Company may also use cash
to finance business acquisitions and stock repurchases from time to time.

      The Company made no repurchases of its common stock under the Company's
stock repurchase plan during the three-months ended November 30, 2004. From time
to time, the Company's Board of Directors has authorized management to
repurchase shares of the Company's common stock. Most recently, during August
2000, the Company announced a 1.0 million share increase in the number of shares
authorized for repurchase. Under this share repurchase plan, management has
existing authorization to purchase, without further announcement, up to 1.2
million shares of the Company's common stock in the open market or otherwise.

      The Company has an agreement with a commercial bank for a $10.0 million
unsecured revolving line of credit through December 28, 2005. Proceeds from this
line of credit, if any, are to be used for working capital and general corporate
purposes including stock repurchases. There have been no borrowings made under
such unsecured revolving line of credit. Under the terms of the line of credit,
borrowings, if any, bear interest at a rate equal to one percent per annum under
the rate in effect from time to time and designated by the commercial bank as
its National Base Rate (5.00% at November 30, 2004). The Company expects to
renew this line of credit on substantially similar terms.

      The Company's European subsidiary, Lindsay Europe, has an unsecured
revolving line of credit with a commercial bank under which it could borrow up
to the Euro equivalent of $2.7 million for working capital purposes. As of
November 30, 2004, there was a $782,000 outstanding balance on this line. Under
the terms of the line of credit, borrowings, if any, bear interest at a floating
rate in effect from time to time designated by the commercial bank as LIBOR+200
basis points. (4.65% at November 30, 2004).

      The Company believes its current cash resources (including cash and
marketable securities balances), projected operating cash flow, and prospective
bank line of credit are sufficient to cover all of its expected working capital
needs, planned capital expenditures, dividends, and other cash needs. During the
three-months ended November 30, 2004, the Company had $7.7 million of securities
that matured or were sold; these funds were used for working capital needs.

MARKET CONDITIONS AND FISCAL 2005 OUTLOOK

For fiscal 2005, the Company expects unit volume growth in the international
markets for irrigation equipment, but the Company remains uncertain as to the
effect of price and pricing policy changes on the demand in our domestic
markets. While many of the major agriculture commodity prices have declined, net
cash farm income domestically is projected to be high, creating favorable
conditions for growers to invest in income producing equipment, such as
irrigation equipment. In addition, demand can be favorably or unfavorably
impacted by weather conditions during the primary selling season, which begins
mid-way through the Company's second quarter. International market demand
remains relatively strong and the weak U.S. dollar results in conditions
favorable for exporting equipment.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

FASB 123R, (revised December 2004), "Share-Based Payment" sets accounting
requirements for "share-based" compensation to employees, including
employee-stock-purchase-plans (ESPPs) and provides guidance on accounting for
awards to non-employees. This Statement will require the Company to recognize in
the income statement the grant-date fair value of stock options and other
equity-based compensation issued to employees, but expresses no preference for a
type of valuation model. For public entities, this Statement is effective for
the first interim period beginning after June 15, 2005. The Company will adopt
this Statement in the fourth quarter of fiscal 2005 and is evaluating this
pronouncement's effect on the Company's financial position and net income.

      FASB 151, "Inventory Costs" eliminates the "so abnormal" criterion in ARB
43 "Inventory Pricing". This Statement no longer permits a company to capitalize
inventory costs on their balances sheets when the production defect rate varies
significantly from the expected rate. The Statement reduces the differences
between U.S. and international accounting standards. This Statement is effective
for inventory cost incurred during annual periods beginning after June 15, 2005.
The Company will adopt this Statement in the first quarter of fiscal 2006 and is
evaluating this pronouncement's effect on the Company's financial position and
net income.

      FASB 153, "Exchanges of Productive Assets" eliminates the exception to the
fair-value principle for exchanges of "similar productive assets," which had
been accounted for based on the book value of the asset surrendered with no gain
recognition. Nonmonetary exchanges have to be accounted for at fair-value,
recognizing any gain or loss, if the transactions meet the commercial-substance
criterion and fair-value determinable. The Statement reduces the differences
between U.S. and international accounting standards. This Statement is effective
for nonmonetary transactions occurring in fiscal periods after June 15, 2005.
The Company will adopt this Statement in the first quarter of fiscal 2006 and is
evaluating this pronouncement's effect on the Company's financial position and
net income.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The market value of the Company's investment securities fluctuates inversely
with movements in interest rates because all of these investment securities bear
interest at fixed rates. Accordingly, during periods of rising interest rates,
the market value of these securities will decline. However, the Company does not
consider itself to be subject to material market risks with respect to its
portfolio of investment securities because the maturity of these securities is
relatively short, making their value less susceptible to interest rate
fluctuations.

      The Company has manufacturing operations in the United States, France,
Brazil, and South Africa. The Company has sold products throughout the world and
purchases certain 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 local currency. The Company's most
significant transactional foreign currency exposures are the Euro, Brazilian
real, and the South African rand 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.

                                       19
<PAGE>

      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, Brazilian real, and the
South African rand in relation to the U.S. dollar.

ITEM 4 - CONTROLS AND PROCEDURES

Based upon their evaluation of the effectiveness of the Company's disclosure
controls and procedures (as defined in Exchange Act Rules 13a-15(e) and
15d-15(e), management, including the Chief Executive Officer and Chief Financial
Officer, concluded that the Company's disclosure controls and procedures were
effective as of November 30, 2004.

      There were no significant changes in the Company's internal controls or in
other factors that could significantly affect these controls subsequent to
November 30, 2004 through the date of this Quarterly Report on Form 10-Q,
including any corrective actions with regard to significant deficiencies and
material weaknesses.

PART II - OTHER INFORMATION

ITEM 1 - LEGAL PROCEEDINGS

In the ordinary course of its business operations, the Company is involved, from
time to time, in commercial litigation, employment disputes, administrative
proceedings, and other legal proceedings. These include a consent decree that
the Company entered in 1992 with the U.S. Environmental Protection Agency
concerning groundwater contamination at its Lindsay, Nebraska facility, which is
included as an EPA superfund site. Management does not believe that these
matters, individually or in the aggregate, are likely to have a material adverse
effect on the Company's consolidated financial condition, results of operations,
or cash flows.

ITEM 2 - UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF  PROCEEDS

The Company made no repurchases of its common stock under the Company's stock
repurchase plan during the three months ended November 30, 2004; therefore,
tabular disclosure is not presented. From time to time, the Company's Board of
Directors has authorized management to repurchase shares of the Company's common
stock. Most recently, during August 2000, the Company announced a 1.0 million
share increase in the number of shares authorized for repurchase. Under this
share repurchase plan, management has existing authorization to purchase,
without further announcement, up to 1.2 million shares of the Company's common
stock in the open market or otherwise.
