NOTE 3 - INVENTORIES

         Inventories consist of the following (amounts in thousands):


                  APRIL 30,   OCTOBER 31,
                    2001        2000

                   $25,660    $24,087
                   =======    =======


         Inventories are stated at the lower of cost or market. Inventories in
the United States are primarily valued by the last-in, first-out (LIFO) cost
method. The primary method used for all other inventories is first-in, first-out
(FIFO). An actual valuation of inventory under the LIFO method can be made only
at the end of each year based on the inventory levels and costs at that time.
Accordingly, interim LIFO calculations must necessarily be based on management's
estimates of expected year-end inventory levels and costs. Because these are
subject to many factors beyond management's control, interim results are subject
to the final year-end LIFO inventory valuation.

NOTE 7 - NEWLY ISSUED ACCOUNTING STANDARD

As of November 1, 2000, the Company adopted Financial Accounting Standards Board
Statement No. 133, Accounting for Derivative Instruments and Hedging Activities
(Statement 133). The adoption of Statement 133 did not effect the Company's
financial statements since the accounting treatment for the financial
instruments held at the time did not change.

As a result of adoption of Statement 133, the Company recognizes all derivative
financial instruments, such as interest rate swap contracts and foreign exchange
contracts, in the consolidated financial statements at fair value regardless of
the purpose or intent for holding the instrument. Changes in the fair value of
derivative financial instruments are either recognized periodically in income or
in shareholders' equity as a component of comprehensive income depending on
whether the derivative financial instrument qualifies for hedge accounting, and
if so, whether it qualifies as a fair value hedge or cash flow hedge. Generally,
changes in fair values of derivatives accounted for as fair value hedges are
recorded in income along with the portions of the changes in the fair values of
the hedged items that

                                       8
   11
relate to the hedged risk(s). Changes in fair values of derivatives accounted
for as cash flow hedges, to the extent they are effective as hedges, are
recorded in other comprehensive income net of deferred taxes. Changes in fair
values of derivatives not qualifying as hedges are reported in income.

NOTE 8 - CONTINGENCIES

The Company is subject to various legal actions, governmental audits, and
proceedings relating to various matters incidental to its business including
product liability and environmental claims. While the outcome of such matters
cannot be predicted with certainty, in the opinion of management, after
reviewing such matters and consulting with the Company's counsel and considering
any applicable insurance or indemnifications, any liability which may ultimately
be incurred is not expected to materially affect the consolidated financial
position, cash flows or results of operations of the Company.

OPERATIONS

THREE MONTH PERIOD ENDED APRIL 30, 2001 VS. THREE MONTH PERIOD ENDED APRIL 30,

NET SALES

         The Company had net sales of $60.2 million in the second quarter of
fiscal 2001 representing a 2.2 percent increase over 2000's second quarter sales
of $58.9 million. This increase can generally be attributed to an increase in
the unit volume of worldwide sales. Had currency values been unchanged from the
second quarter of 2000, net sales in the second quarter of 2001 would have been
$3.0 million higher, or 7.3 percent greater overall.

         North American sales increased 2.2 percent in the second quarter of
2001 as compared to the same quarter in 2000. The Healthcare market was
responsible for the majority of the growth in North America during the three
months ended April 30, 2001. Sales in Europe increased 20.9 percent as compared
to the same period in 2000, and were up 28.5 percent when expressed in local
currency. All three markets displayed strong double-digit gains in sales. Sales
in Japan were down 7.2 percent as compared to the same quarter last year, but
were 4.6 percent higher when expressed in local currency. The increase in sales
was primarily concentrated in the Healthcare market. Asia/Pacific sales were
flat quarter over quarter, however sales increased 12.1 percent excluding
changes in currency values. The majority of the increase in Asia/Pacific is due
to sales growth throughout Australia and strong healthcare sales throughout
Asia/Pacific. Second quarter Latin American sales decreased 11.7 percent as
compared to the same period in 2000, but were up 5.4 percent when expressed in
local currency. The increase in local currency sales was primarily concentrated
in the Potable Water and Healthcare market.

         On a currency adjusted basis, all geographic operating segments
achieved sales increases in the potable water market. This strength was
primarily driven by increased overseas sales (up 21.8 percent) tempered by
moderate sales growth in North America (up 3.7 percent) associated with OEM
customers, direct marketing companies, and appliance manufacturers. Fluid
processing sales were most affected by the slowing economies in the US and
overseas. Healthcare sales continue to benefit from a continued focus by
management on competitively favorable niches.

GROSS PROFIT

         The Company's gross profit increased $1.2 million to $26.7 million in
the second quarter of 2001 from $25.5 million in the second quarter of 2000.
Gross profit as a percentage of net sales (gross margin) increased during that
same period from 43.2 percent in 2000 to 44.3 percent in 2001. The primary
factor that contributed to the improved gross margin in 2001 was increased
healthcare sales which generally carry higher margins.

OPERATING EXPENSES

         Selling, general and administrative expenses increased 4.1 percent
reflecting the Company's focus on restraining discretionary spending. Expense
categories within SG&A reflected nominal increases or decreases consistent with
the Company's cost-management strategy. Research, development and engineering
expenses were generally flat -- 5.7 percent of sales in the second quarter of
fiscal 2000 compared to 5.5 percent of sales in the second quarter of fiscal
2001. This level of research and development reflects the Company's continued
focus on the development of new products and technologies.

OPERATING INCOME

         As a result of the above, operating income increased $0.6 million, or
9.0 percent, to $6.9 million or 11.5 percent of sales in the second quarter of
fiscal 2001 compared to $6.4 million or 10.8 percent of sales in the second
quarter of 2000.

NON-OPERATING ACTIVITY

         Interest income increased by $0.1 million in the second quarter of 2001
compared to the second quarter of 2000 as the Company maintained higher levels
of invested cash. See "Financial Position and Liquidity" below. Exchange gains
(losses) improved by $0.2 million in 2001 over 2000 as well. As disclosed in
Note 6 to the condensed consolidated financial statements, other income
(expenses) was relatively minor in both periods as no material activity occurred
in either one.

]INCOME TAXES

         The Company's effective income tax rate for the second quarter of 2001
was 36.2 percent compared to 37.5 percent in the second quarter of 2000. The
decrease primarily reflects the recognition of incremental tax credits, certain
tax planning initiatives, and a change in the mix of income attributed to the
various countries in which the Company does business.

NET SALES

         The Company had net sales of $118.8 million in the first six months of
fiscal 2001 representing a 1.8 percent increase over 2000's comparable sales of
$116.6 million. This increase can generally be attributed to an increase in the
unit volume of worldwide sales. Had currency values been unchanged from the
first six months of 2000, net sales in the first six months of 2001 would have
been $5.6 million higher, or 6.6 percent greater overall.

         North American sales increased 2.3 percent in the first six months of
2001 as compared to the same period in 2000. The potable water market was
responsible for nearly all of this growth. Sales in Europe increased 11.9
percent as compared to the same period in 2000, but were up 22.3 percent when
expressed in local currency. All three markets displayed strong double-digit
gains in sales. Sales in Japan were only 0.6 percent higher as compared to the
same period last year, but 10.9 percent higher when expressed in local currency.
Local currency sales increased in all three markets. Asia/Pacific sales
decreased by 0.5 percent as compared to the same period last year but, excluding
changes in currency values over the period, increased 11.5 percent. The majority
of the increase in Asia/Pacific is due to expanding sales in both the potable
water and healthcare segments throughout the Asian and Pacific markets. Sales in
Latin America decreased 17.0 percent (7.1 percent in local currency). This
decrease is primarily attributable to a large one-time contract completed and
shipped in the first quarter of fiscal 2000.

         On a currency adjusted basis, all geographic operating segments
achieved sales increases in the potable water market. This strength was
primarily driven by increased overseas sales (up 18.9 percent) as well as
increased sales in North America (up 5.9 percent) associated with OEM customers,
direct marketing companies, and appliance manufacturers. Fluid processing sales
were adversely affected by the slowing economies in the US and overseas as well
as a large one-time contract completed and shipped in the first quarter of
fiscal 2000. Healthcare sales continue to benefit from a continued focus by
management on competitively favorable niches.

GROSS PROFIT

         The Company's gross profit increased $1.9 million to $51.7 million in
the first six months of 2001 from $49.8 million in the first six months of 2000.
Gross profit as a percentage of net sales (gross margin) increased during that
same period from 42.7 percent in 2000 to 43.6 percent in 2001. The primary
factors that contributed to the improved gross margin in 2001 were a large
one-time contract completed and shipped in the first quarter of 2000 which
carried a low margin and increased healthcare sales in 2001 which generally
carry a higher margin.

OPERATING EXPENSES

         Selling, general and administrative expenses increased 2.0 percent in
the first six months of 2001 compared to the prior period reflecting the
Company's continued focus on restraining discretionary spending. Expense
categories within SG&A reflected nominal increases or decreases consistent with
the Company's cost-management strategy. Research, development and engineering
expenses were 5.6 percent of sales in both the first six months of 2001 and
2000. This level of research and development reflects the Company's continued
focus on the development of new products and technologies.

OPERATING INCOME

         As a result of the above, operating income increased $1.2 million, or
10.2 percent, to $13.0 million or 10.9 percent of sales in the first six months
of fiscal 2001 compared to $11.8 million or 10.1 percent of sales in the first
six months of 2000.

NON-OPERATING ACTIVITY

         Interest income increased by $0.3 million in the first six months of
2001 compared to the first six months of 2000 as the Company maintained higher
levels of invested cash. See "Financial Position and Liquidity" below. As
disclosed in Note 6 to the condensed consolidated financial statements, other


                                       13
   16
income (expenses) was relatively minor in both periods as no material activity
occurred in either of the two periods.

INCOME TAXES

         The Company's effective income tax rate for the first six months of
2001 was 36.2 percent compared to 37.8 percent in the first six months of 2000.
The decrease primarily reflects the recognition of incremental tax credits,
certain tax planning initiatives, and a change in the mix of income attributed
to the various countries in which the Company does business.

FINANCIAL POSITION AND LIQUIDITY

         The Company assesses its liquidity in terms of its ability to generate
cash to fund operating and investing activities. Of particular importance to the
management of liquidity are cash flows generated by operating activities,
capital expenditure levels, and adequate bank financing alternatives.

         The Company manages its worldwide cash requirements considering the
cost effectiveness of the funds available from the many subsidiaries through
which it conducts its business. Management believes that its existing cash
position and available sources of liquidity are sufficient to meet current and
anticipated requirements for the foreseeable future.

         Set forth below is selected key cash flow data (in thousands of
dollars):

OPERATING ACTIVITIES:
Net cash provided by net income plus
depreciation,
     Amortization and non-cash compensation           $ 13,302     $ 11,941
Accounts receivable                                        995        2,264
Inventories                                             (2,645)        (376)
Accounts payable and accrued expenses                    1,985         (333)
Net cash provided by operating activities               11,441       13,579

INVESTING ACTIVITIES:
Proceeds from surrender of life insurance policies        --            569
Acquisitions of companies, net of cash acquired         (4,489)      (2,885)

FINANCING ACTIVITIES:
Net change in total debt                                  (482)      (4,511)
Retirement of Common Stock                                --         (1,154)




         The net cash provided by net income plus depreciation, amortization and
non-cash compensation is an important measurement of cash generated from the
earnings process. Net income plus depreciation, amortization and non-cash
compensation of $13.3 million increased 11.4 percent in the first six months of
2001 as compared to the same period in 2000 reflecting the Company's increased
sales volume, increased gross profit, and improved operating profit margin as
discussed above. Accounts receivable continue to provide positive cash from
operating activities despite the Company's rising sales volume, (albeit at a
lower level in the first six months of 2001 vs. the comparable period in fiscal
2000). This results from a continued focus by the Company on improving the
efficiency of international receivable

   17
management. The increase in inventory over the six months ended April 30, 2001
primarily relates to the timing of certain sales shipments. This use of cash was
offset by a corresponding source of cash in accounts payable and accrued
expenses.

         In the second quarter of fiscal 2001, CUNO closed on two acquisitions -
a product line in Australia and a distributor in Europe for a total of $4.5
million. These acquisitions do not have a material effect on the Company's
historical financial statements or pro forma operating results. In the second
quarter of fiscal 2000, the Company made a contingent consideration payment of
$2.9 million related to the acquisition of Chemical Engineering Corporation
(CEC). This payment was recorded as additional goodwill. There will be no future
contingency payments related to the CEC acquisition. The acquisition of CEC
included certain life insurance policies on key officers of CEC. In the second
quarter of 2000, CUNO elected to surrender these policies for their cash
surrender value upon settlement.

         The Company paid all outstanding borrowings under its revolving credit
facility in fiscal 2000. No amounts have been outstanding under the revolving
credit facility in fiscal 2001. During the first quarter of 2000, a significant
portion of the Company's outstanding performance shares vested. In connection
therewith, the Company utilized $1.2 million in cash to pay applicable employee
withholding taxes on the common shares earned in return for shares of the
Company's Common Stock then retired.

MARKET RISK DISCLOSURES

         The Company's earnings and cash flows are subject to fluctuations due
to changes in foreign currency exchange rates. The Company utilizes forward
foreign exchange contracts to hedge certain firm sales commitments and
anticipated, but not yet committed, intercompany sales (primarily parent company
export sales to subsidiaries at pre-established U.S. dollar prices) and other
specific and identified exposures. The terms of the forward foreign exchange
contracts are generally matched to the underlying transaction being hedged, and
are typically under 90 days. Because such contracts are directly associated with
identified transactions, they are an effective hedge against fluctuations in the
value of the foreign currency underlying the transaction. The Company generally
does not hedge overseas sales denominated in foreign currencies or translation
exposures. The Company does not enter into financial instruments for speculation
or trading purposes.

         There have been no material changes in the information reported in the

Disclosures" section of Management's Discussion and Analysis of Financial
Condition and Results of Operations.
