              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


Note A - Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of
Donaldson Company, Inc. (the Company) have been prepared in accordance with
accounting principles generally accepted in the United States and the
instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do
not include all of the information and footnotes required for complete financial
statements. In the opinion of management, all adjustments considered necessary
for a fair presentation have been included. Operating results for the three
month period ended October 31, 2001 are not necessarily indicative of the
results that may be expected for the year ending July 31, 2002. For further
information, refer to the consolidated financial statements and footnotes
thereto included in Donaldson Company, Inc. and subsidiaries' Annual Report on
Form 10-K for the year ended July 31, 2001. Certain amounts in prior periods
have been reclassified to conform to the current presentation. The
reclassifications had no impact on the net earnings as previously reported.

Note B - Net Earnings Per Share

The Company's basic net earnings per share is computed by dividing net earnings
by the weighted average number of outstanding common shares. The Company's
diluted net earnings per share is computed by dividing net earnings by the
weighted average number of outstanding common shares and dilutive shares
relating to stock options.

The following table presents information necessary to calculate basic and
diluted net earnings per common share:

   Earnings before income taxes    $ 15,163    $ 12,999    $ (4,156)   $ 24,006

Note E - Derivative Instruments and Hedging Activities

The Company adopted Statement of Financial Accounting Standard (SFAS) No. 133,
"Accounting for Derivative Instruments and Hedging Activities" as amended by
SFAS No. 138, "Accounting for Certain Derivative Instruments and Certain Hedging
Activities - an amendment of FASB Statement No. 133." effective beginning fiscal
2001. SFAS 133 and SFAS 138 require the Company to


                                       6



recognize all derivatives on the balance sheet at fair value. Derivatives that
are not hedges must be adjusted to fair value through income. If the derivative
is a hedge, depending on the nature of the hedge, changes in the fair value of
the hedged assets, liabilities or firm commitments are recognized through
earnings or in other comprehensive income until the hedged item is recognized in
earnings. The ineffective portion of a derivative's change in fair value will be
immediately recognized in earnings. The Company enters into foreign exchange
contracts and other hedging activities to mitigate potential foreign currency
gains and losses relative to local currencies in the markets to which it sells.

In order to comply with the implementation requirements of SFAS 133 and SFAS
138, the Company undertook a comprehensive review of its contractual
relationships to ensure that all potential free-standing and embedded
derivatives were identified. As a result, all of the Company's existing
derivative positions qualified for hedge accounting per SFAS 133 and SFAS 138,
and the impact of adoption was not considered material to the Company's results
of operations or financial position. The Company's documentation policies for
derivatives were revised as considered necessary to comply with SFAS 133
requirements. However, the Company made no substantive changes to its risk
management strategy as a result of adopting SFAS 133 and SFAS 138. As a result
of the implementation of SFAS 133 and SFAS 138, the Company has recorded a
credit to other comprehensive income of $0.1 million at October 30, 2001.

In June 2001 the Company entered into an interest rate swap agreement which was
determined to be a fair value hedge under SFAS 133 and SFAS 138. As of October
31, 2001, the interest rate swap had a fair value of $1.9 million.

Note F - New Accounting Standards

In June 2001, the Financial Accounting Standards Board issues SFAS No. 141,
"Business Combinations," and SFAS No. 142, "Goodwill and Other Intangible
Assets." Major provisions of these statements are as follows: all business
combinations must now use the purchase method of accounting, the pooling of
interest method of accounting is now prohibited; intangible assets acquired in a
business combination must be recorded separately from goodwill if they arise
from contractual or other legal rights or are separable from the acquired entity
and can be sold, transferred, licensed, rented or exchanged, either individually
or as a part of a related contract, asset or liability; goodwill and intangible
assets with indefinite lives are not amortized, but tested for impairment
annually, except in certain circumstances, and whenever there is an impairment
indicator; all acquired goodwill must be assigned to reporting units for
purposes of impairment testing and segment reporting; effective August 1, 2002,
goodwill is no longer subject to amortization. The Company has adopted the
provisions of these statements as of August 1, 2001. As required by SFAS 142,
the Company is in the process of performing an impairment test on goodwill as of
the adoption date. Thereafter, the Company will perform impairment tests
annually and whenever events or circumstances occur indicating that goodwill or
other intangible assets might be impaired. As of August 1, 2001, the Company is
no longer amortizing goodwill. Goodwill amortization expense was $0.7 million
net of income taxes for the quarter ended October 31, 2000. The Company
estimates that goodwill amortization expense would have been approximately $0.6
million net of income taxes in the first quarter of fiscal 2002. The following
table presents a reconciliation of net income and earnings per share adjusted
for the exclusion of goodwill, net of income taxes:

As of July 31, 2001, goodwill was $57.8 million. There were no additions during
the first quarter of fiscal 2002. Other intangible assets, which include patents
and trademarks of $0.3 million as of October 31, 2001, are being amortized over
their useful lives.

Note G - Acquisitions

The Company completed the purchase of all of the outstanding shares of AirMaze
Corporation for $31.9 million in cash effective November 1, 1999. AirMaze
Corporation was merged into Donaldson Company, Inc. effective April 1, 2000.
AirMaze products include heavy-duty air and liquid filters, air/oil separators
and high purity air filter products. AirMaze manufacturing facilities are
located in Stow, Ohio and Greenville, Tennessee. The excess of purchase price
over the fair values of the net assets acquired was $26.8 million and has been
recorded as goodwill. AirMaze operations are a part of the Company's Engine
Products segment. As of October 31, 2001, the balance of restructuring
liabilities recorded in conjunction with the acquisition was approximately $0.2
million for costs associated with the termination and relocation of employees.
There were no costs incurred and charged to this reserve associated with the
termination and relocation of employees for the three months ended October 31,
2001. The integration of AirMaze resulted in a reduction in the work force of
approximately 15 employees during fiscal 2001. The remaining acquisition related
restructuring activities are expected to be completed by the end of fiscal 2002.

The Company acquired the DCE dust control business of Invensys, plc for $56.4
million effective February 1, 2000. DCE, headquartered in Leicester, England
(UK) with smaller facilities in Germany and the United States and assembly
operations in South Africa, Australia and Japan, is a major participant in the
global dust collection industry. The excess of purchase price over the fair
values of the net assets acquired was $33.2 million and has been recorded as
goodwill. DCE operations are a part of the Company's Industrial Products
segment. As of October 31, 2001, the balance of restructuring liabilities
recorded in conjunction with the acquisition was approximately $0.7 million of
costs associated with the closure and sale of acquired facilities as well as
termination and relocation of employees. Costs incurred and charged to these
reserves associated with the closure and sale of acquired facilities amounted to
$0.9 million and the termination and relocation of


                                       8



employees amounted to $0.5 million for the three months ended October 31, 2001.
The integration of DCE resulted in a reduction in the work force of
approximately 140 employees during fiscal 2001. The remaining acquisition
related restructuring activities are expected to be completed by the end of
fiscal 2002.


Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations.

Liquidity and Capital Resources

The Company generated $43.9 million of cash and cash equivalents from operations
during the first three months of fiscal 2002. Operating cash flows increased by
$42.2 million from the same period in the prior year due to decreases in
accounts receivable and inventory compared to prior year increases in those
balances. These cash flows, plus borrowings from the Company's credit facility,
were used during the first three months of fiscal 2002 primarily to support
$11.0 million in capital additions, repurchase $8.4 million of treasury stock
and for the payment of $3.3 million in dividends. At the end of the first
quarter, the Company had remaining authority to purchase 4.2 million shares of
common stock under the share repurchase program authorized in January 2001.

At the end of the first quarter, the Company held $57.5 million in cash and cash
equivalents. Short-term debt totaled $58.0 million, down from $59.4 million at
July 31, 2001. The amount of unused lines of credit as of October 31, 2001 was
approximately $82.8 million. Long-term debt of $101.4 million at October 31,
2001, up from $99.3 million at July 31, 2001, represented 23.5 percent of total
long-term capital, down slightly from 23.7 percent at July 31, 2001.

The Company believes that the combination of present capital resources,
internally generated funds, and unused financing sources are adequate to meet
cash requirements for the next twelve month period.

Results of Operations

The Company is a leading worldwide manufacturer of filtration systems and
replacement parts. The Company's product mix includes air and liquid filters and
exhaust and emission control products for mobile equipment; in-plant air
cleaning systems; air intake systems for industrial gas turbines; and
specialized filters for such diverse applications as computer disk drives,
aircraft passenger cabins and semiconductor processing. Products are
manufactured at more than three dozen plants around the world and through three
joint ventures. The Company has two reporting segments engaged in the design,
manufacture and sale of systems to filter air and liquid and other complementary
products. The two segments are Engine Products and Industrial Products. Products
in the Engine Products segment consist of air intake systems, exhaust systems,
liquid filtration systems and replacement filters. The Engine Products segment
sells to original equipment manufacturers (OEMs) in the construction,
industrial, mining, agriculture and transportation markets and to independent
distributors, OEM dealer networks, private label accounts and large private
fleets. Products in the Industrial Products segment consist of dust, fume and
mist collectors, static and pulse-clean air filter systems for industrial gas
turbines, computer disk drive filter products and other specialized air


                                       9



filtration systems. The Industrial Products segment sells to various industrial
end-users, OEMs of gas-fired turbines, OEMs and end users requiring highly
purified air.

The Company reported net earnings for the first quarter ended October 31, 2001
of $19.7 million, up from the $16.8 million recorded in the first quarter of the
prior year. Total net sales for the three months ended October 31, 2001 of
$288.4 million were down 0.5 percent from prior year sales of $289.9 million.
Foreign currency translation reduced first quarter net sales by 0.6 percent and
the exit from an unprofitable block of business in the second quarter of fiscal
2001 reduced first quarter net sales by 0.9 percent. Net of these factors, first
quarter net sales were up 1.0 percent. The increase in net earnings reflects the
Company's efforts to lower costs resulting in an increase in gross margin as
compared to the first quarter of the prior year. This along with the lowering of
the Company's effective income tax rate in the third quarter of fiscal 2001 due
to increased profitability from foreign operations helped to offset the effect
of negative effects on net sales discussed above. Diluted net earnings per share
were 43 cents, up 16.2 percent from prior year diluted net earnings per share of
37 cents as the average number of shares outstanding increased slightly compared
to the prior year period.

For the first quarter, net sales in the Industrial Products segment of $131.9
million increased 7.5 percent from $122.7 million in the prior year. This
increase was driven by the continued strength in gas turbine product sales with
an increase of 66.3 percent to net sales of $57.2 million from $34.4 million in
the prior year. Gas turbine sales grew in all major geographic regions as the
multi-year ramp up in gas turbine power plant additions continued into the first
quarter of fiscal 2002, and the Company continues to be the supplier of choice
for air inlet filtration systems. For the quarter, sales of dust collection
products were $48.2 million, a decrease of 19.3 percent from $59.8 million in
the same period in the prior year. As U.S. industrial production recorded its
13th consecutive monthly decrease and capacity utilization fell to its lowest
levels since June 1983, U.S. manufacturers capital spending remained at
recession-like levels. Caution in capital spending levels is spreading to other
geographic regions, particularly Europe. These factors have created a difficult
operating environment for industrial dust collection equipment sales. For the
quarter, sales of special application products were $26.4 million, a 7.2 percent
decrease from prior year sales of $28.5 million. Within special application
products, a modest increase in disk drive filter sales was offset by weak sales
in aircraft cabin air filtration and photolithography filtration

For the first quarter, net sales in the Engine Products segment of $156.5
million decreased 6.4 percent from $167.1 million in the prior year. The
decrease in net sales reflects U.S. economic weakness as well as weakness of
foreign currency against the U.S. dollar. Within the Engine Products segment,
net sales of medium and heavy-duty truck products of $21.6 million decreased 8.5
percent in the quarter from $23.7 million in the prior year. The decrease in the
first quarter reflects the decrease in the North American truck market and the
Company's decision in the second quarter of fiscal 2001 to discontinue a block
of business with a major customer due to unfavorable commercial terms. Excluding
this exit from a block of business in the prior year, net sales were up 3.4
percent. Truck build data continues to show that NAFTA build rates have
stabilized, but at dramatically lower levels than a year ago. Sales of off-road
products totaling $45.9 million declined slightly for the third quarter posting
a decrease of 1.1 percent from $46.5 million over the same period in the prior
year. Excluding the effects of currency translation, results were essentially
flat. Stronger defense product sales were offset by weak conditions in markets
for construction and light industrial equipment. Sales of aftermarket products


                                       10



for the first quarter were $88.9 million, a decrease of 8.3 percent from $97.0
million in the prior year. North American and European freight volumes and
vehicle utilization rates continue to be weak, negatively affecting aftermarket
product sales.

Consolidated gross margin for the first quarter of fiscal 2002 was 30.6 percent,
up from 29.7 percent in the same quarter of the prior year. The year-over-year
improvement was attributable to improved product mix and the realized benefits
of last year's plant rationalization efforts, partially offset by on-going plant
rationalization efforts costing 2 cents per share in the quarter.

Operating expenses during the first quarter of fiscal 2002 were $59.3 million
(20.5 percent of sales), compared to $58.0 million (20.0 percent of sales) in
the same quarter of fiscal 2001. Included in operating expenses in the prior
year was $1.0 million of goodwill amortization and the positive impact from a
warranty settlement of $1.7 million. Excluding these two adjustments, operating
expenses were 20.2 percent of sales in the prior year.

Other income for the first quarter of $0.7 million increased $1.5 million from
$0.8 million of expense in the same period in the prior year. Other income for
the first quarter consisted of income from unconsolidated affiliates of $1.0
million, interest income of $0.2 million and other expense of $0.5 million. For
the quarter, interest expense was $2.4 million, down $0.7 million from the first
quarter in the prior year, reflecting lower short-term debt levels as compared
to the prior year.

The income tax rate for the quarter was 28 percent, down from 30 percent in
fiscal 2001. The tax rate was adjusted in the third quarter of fiscal 2001 to
provide for the increased contributions from the Company's international
operations and reflects the foreign tax credit generated by the receipt of a
dividend from the Company's operations in Japan and the reduction of a net
operating loss valuation allowance in our Mexico operations. The Company
anticipates that it will continue to have a higher proportion of income coming
from its international operations located in Europe and Asia. As a result, the
Company anticipates maintaining the 28 percent tax rate through the end of the
fiscal year.

Total backlog of $331 million at October 31, 2001 was up 5 percent relative to
the same period in the prior year and down 7 percent from the prior quarter end.
In the Industrial Products segment, total backlog increased 6 percent from the
same period in the prior year but decreased 11 percent from the prior quarter
end. In the Engine Products segment, total backlog increased 4 percent from the
same period in the prior year but increased 2 percent from the prior quarter
end.

Hard order backlog - goods scheduled for delivery in 90 days - was $176 million,
down 4 percent from the same period in the prior year and down 2 percent from
the prior quarter end. In the Industrial Products segment, hard order backlog
decreased 7 percent from the same period in the prior year and decreased 1
percent from the prior quarter end. In the Engine Products segment, hard order
backlog decreased 1 percent from the same period in the prior year and decreased
4 percent from the prior quarter end.

The impact of foreign currency translation, resulted in a decrease in net sales
of $1.8 million and virtually no impact on net earnings for the first quarter.
The decrease in net sales was a direct result of the weakness of currencies
against the U.S. dollar in several of the Company's operating locations
throughout the world. The currencies that impacted the Company's sales results
the most were the Japanese Yen and the South African Rand, which resulted in a
decrease in net sales of $2.4 million and $0.9


                                       11



million, respectively. The Australian Dollar also had a negative impact on the
Company's first quarter net sales with a decrease in net sales of $0.4 million.
The negative impact of these currencies was offset by the foreign exchange
impact of the Euro, which resulted in a gain of $1.9 million for the quarter. On
a local currency basis, revenues outside the U.S. were flat. Using last year's
foreign exchange rates, total worldwide revenue would have been flat versus the
reported decrease of 0.5 percent.


Outlook

Within the Industrial Products segment, the Company expects continued strength
in gas turbine sales throughout calendar year 2002, although the year-over-year
growth rates are expected to level off from the recent high levels. The
difficult operating conditions for dust collection product sales and portions of
special applications products are expected to persist for at least the next
quarter. Within the Engine Products segment, the Company anticipates continued
weak economic conditions, but easing year-over-year comparisons should begin
following last year's second quarter slowdown in the end markets for Engine
Products.

Recognizing the difficult economic conditions for many of the end markets, the
Company will continue to focus on managing its cost structure through continued
discretionary expense controls, lower spending for plant rationalization efforts
compared to the prior year, and other initiatives designed to increase the
operating efficiencies of the business.

Item 3.  Quantitative and Qualitative Disclosure about Market Risk

         The Company's exposure to market risks for changes in interest rates
         relates primarily to our short-term investments, short-term borrowings
         and interest rate swap agreement. We have no earnings or cash flow
         exposure due to market risks on our long-term debt obligations as a
         result of the fixed-rate nature of the debt. However, interest rate
         changes would affect the fair market value of the debt. At October 31,
         2001, the fair value of the Company's long-term debt approximates
         market. Market risk is estimated as the potential decrease in fair
         value resulting from a hypothetical one-half percent increase in
         interest rates and amounts to approximately $3.2 million.

         On June 6, 2001, the Company entered into an interest rate swap
         agreement effectively converting a portion of the Company's interest
         rate exposure from a fixed rate to a variable rate basis to hedge
         against the risk of higher borrowing costs in a declining interest rate
         environment. The Company does not enter into interest rate swap
         contracts for speculative or trading purposes; as the differential to
         be paid or received on the interest rate swap agreement is accrued and
         recognized as an adjustment to interest expense as interest rates
         change. The interest rate swap agreement has an aggregate notional
         amount of $27.0 million maturing on July 15, 2008. The variable rate is
         based on the current six-month London Interbank Offered Rates
         ("LIBOR"). This transaction had no affect on interest expense for the
         quarter ended October 31, 2001.

         The Company does not enter into market risk-sensitive instruments for
         trading purposes to generate revenues. There have been no material
         changes in the reported market risk of the Company since July 31, 2001.
         See further discussion of these market risks in the Donaldson Company,
         Inc. Annual Report on Form 10-K for the year ended July 31, 2001.
