         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 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 4 - NEW ACCOUNTING STANDARD

         The Company has adopted Statement of Financial Accounting Standard No.
130, "Reporting Comprehensive Income" effective November 1, 1998. This Statement
requires that all components of comprehensive income and total comprehensive
income be reported and that changes be shown in a financial statement displayed
with the same prominence as other financial statements. The Company has elected
to disclose this information in its Statement of Stockholders' Equity. Total
comprehensive income (loss) was comprised of the following (in thousands of
dollars):

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

THREE MONTH PERIOD ENDED JANUARY 31, 1999 VS. THREE MONTH PERIOD ENDED JANUARY
31, 1998

NET SALES

         The Company had net sales of $50.6 million in the first quarter of
fiscal 1999 representing a 15.0 percent increase over 1998's first quarter sales
of $44.0 million. Currency values had an immaterial effect on overseas net sales
(quarter over quarter) when translated from local currency into US dollars.

         Sales from US operations increased $5.9 million or 26.6 percent led by
a strong performance in the Water Group. The Water Group's recently introduced
range of new appliance filters designed to target the OEM market, as well as the
purchase of Chemical Engineering Corporation, a manufacturer of water treatment
equipment in March 1998, are primarily responsible for the increase. Sales from
overseas operations increased $0.7 million or 3.1 percent. Local currency sales
in Europe, Australia and Brazil increased 4.6 percent, 16.9 percent and 12.0
percent, respectively. The continuing depressed economies in the Asian region
have reduced sales in Japan and Singapore as compared to the same period in the
prior year.

GROSS PROFIT

         The Company's gross profit increased $0.9 million to $19.9 million in
the first quarter of 1999 from $19.0 million in the first quarter of 1998. Gross
profit as a percentage of net sales decreased to 39.2 percent from 43.1 percent.
This decrease is attributable to a higher mix of Water Group sales that
generally carry a lower gross margin than sales to either the healthcare or
fluid processing markets; start-up costs primarily associated with a new product
in the Water Group; and, higher manufacturing costs in the US membrane operation
associated with the introduction of new manufacturing processes. Additionally,
pricing pressure on certain products sold in Japan also contributed to the
decline in gross margin.


                                      -6-

OPERATING EXPENSES

         Selling, general, and administrative expenses increased by $2.0 million
in the first quarter of 1999 over the fist quarter of 1998, representing a 16.0
percent increase. Approximately $1.0 million of the increase relates to normal
operating expenses attributed to companies acquired subsequent to the first
quarter of 1998, but prior to the first quarter of 1999. Results of operations
for acquired companies are included in the accompanying financial statements
from the date of acquisition. Research, development and engineering expenses
were relatively flat quarter over quarter.

OPERATING INCOME

         As a result of the above, operating income decreased $1.1 million, or
29.1 percent, to $2.7 million or 5.3 percent of sales in the first quarter of
1999 as compared to $3.8 million or 8.6 percent of sales in the first quarter of
1998.

NONOPERATING ACTIVITY

         Interest expense increased to $0.4 million in the first quarter of 1999
from $0.2 million in the first quarter of fiscal 1998. The increase in interest
expense primarily results from an increase in debt associated with acquisitions
and the expansion of the Company's manufacturing capabilities throughout fiscal
year 1998. As detailed in Note 5 to the condensed financial statements, other
income in the first quarter of 1998 benefited from the sale of a tract of land
in Australia, which was unrelated to the business, resulting in a gain of $0.3
million.

INCOME TAXES

         The Company's effective income tax rate for the first quarter of 1999
was 36.6% compared to 35.0% in the first quarter of 1998. The increase reflects
a change in the mix of income attributed to various countries and their taxing
authorities 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 in 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 with consideration
of the cost effectiveness of the available funds 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.

Net cash provided by operating activities                     4,724         245

INVESTING ACTIVITIES:

Net change in total debt                                     (3,089)      4,216



         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 before significant non-cash charges. The decrease in net income
plus depreciation, amortization and non-cash compensation of $0.9 million
reflects the Company's reduced gross profit margin and increased selling,
general and administrative expenses as discussed previously above. Accounts
receivable were reduced $2.7 million during the first quarter of 1999 due
largely to a concentrated effort by management to improve collections worldwide.
Inventories were reduced $0.8 million in the first quarter of 1999 (vs. an
increase of $0.9 million in the first quarter of 1998) due to a reduction of
inventory in the Water Group which was built-up during the fourth quarter of
1998 to support the first quarter launch of new products.

         Capital expenditures amounted to $3.1 million in the first quarter of
1999 which were primarily comprised of purchases of machinery and equipment.
During the first quarter of fiscal 1998, the Company completed two overseas
acquisitions -- a distribution business in Europe and a product line in
Australia which were comprised primarily of working capital -- for an aggregate
purchase price of $2.2 million. These acquisitions have been accounted for as
purchases and, accordingly, the results of their operations are included in the
Company's consolidated statements of operations from the date of acquisition.

         Due largely to the Company's strong cash flows from operating
activities ($4.7 million) in the first quarter of 1999, the Company was able to
reduce its long-term debt, on a net basis, by $3.1 million.

OTHER MATTERS

BRAZILIAN REAL DEVALUATION

         A significant devaluation in the Brazilian real took place late in the
Company's first quarter. The Company has a subsidiary located in Brazil which
accounted for approximately 7% of consolidated net sales in 1998. Although this
event had a minimal impact on this subsidiary's results of operations in the


                                      -8-
   11
first quarter, any future effects on the business climate in the region are yet
to be determined. A significant portion of the products sold by the subsidiary
in Brazil are manufactured locally - this should help to minimize the impact of
the devaluation on future earnings. See "Market Risk Disclosures" below.

NEW ACCOUNTING STANDARDS

         In June 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information". This statement requires that business
enterprises report in their footnotes certain revenue, expense, profit and asset
information by operating segment and other related disclosures. Operating
segments are components of an enterprise whose performance is regularly reviewed
by management. As required, the Company expects to adopt this standard in its
1999 fourth quarter reporting cycle.

         In February 1998, the Financial Accounting Standards Board issued SFAS
No. 132, "Employers' Disclosures about Pensions and Other Postretirement
Benefits". This statement does not change the measurement or recognition of
pension and other postretirement benefit plans, but it does revise the
disclosure requirements. The adoption of this statement will have no impact on
the Company's consolidated results of operations, financial position or cash
flows. As required, the Company plans to adopt this statement in its 1999 fourth
quarter reporting cycle.

         In June 1998, the Financial Accounting Standards Board issued SFAS No.
133, "Accounting for Derivative Instruments and Hedging Activities". This
statement requires all derivatives to be recorded on the balance sheet at fair
value and provides a comprehensive and consistent standard for the recognition
and measurement of derivatives and hedging activities. The Company is studying
the application of this new statement. The adoption of this statement is not
expected to have a material impact on the consolidated results of operations,
financial position or cash flows. As required, the Company plans to adopt this
statement upon its applicable effective date in fiscal 2000.


COMPLIANCE WITH YEAR 2000

         The Company has substantially completed its internal program to
remediate its Year 2000 requirements. It has completed the remediation of its
information technology systems and has made substantial progress in remediating
its non-information technology. All non-information technology remediation is
expected to be completed in the third quarter of 1999. The Company continues to
communicate with its suppliers, customers and other service providers to
determine the extent of the Company's exposure to the failure of third parties
to remediate their own Year 2000 needs.

         The most likely worst case scenario would be that a failure by the
Company or one or more of its vendors or suppliers to adequately and timely
address the Year 2000 issue could interrupt manufacturing of the Company's
products for an indeterminable period of time. The Company is identifying
alternative vendors should a vendor's ability to meet the Company's raw material
and supply requirements be impacted by the Year 2000 issue. In conjunction with
this effort, the Company continuously monitors its action plans to address its
Year 2000 requirements, including contingencies to address unforeseen problems.
This is potentially a significant issue for most, if not all, companies, with
implications which can not be anticipated or predicted with any degree of
certainty.

         The risk to CUNO resulting from the failure of the Company's own
information systems or third parties to attain Year 2000 readiness is similar to
other manufacturing firms and business enterprises. These risks include (1)
disruptions in information systems used for transaction processing, (2)
disruptions in factories and facilities used in the manufacturing process, (3)
disruptions in the supply of raw materials 


                                      -9-
   12
and other components from major vendors, and (4) disruptions in the shipment of
manufactured goods to major customers due to their Year 2000 noncompliance.

         The Company is expensing software maintenance or modification costs as
incurred. The costs of new leased software is being expensed over the term of
the lease while items of a capital nature are being depreciated over their
estimated useful lives. For expenditures related to Year 2000 to date, the
Company has expensed approximately $50,000 in maintenance or modification costs
(excluding operating lease payments for new systems implemented as part of the
spin-off) and capitalized approximately $100,000. Based on information currently
available, the total remaining maintenance or modification costs are not
expected to be material, while future purchases of a capital nature are expected
to be approximately $300,000.

         The costs of this project and its completion date are based on
management's best estimates, which were derived from numerous assumptions about
future events, including the availability of certain resources, third party
remediation plans, and other factors. There can be no guarantee that these
estimates will be achieved and actual results could differ materially from those
plans.

EUROPEAN ECONOMIC AND MONETARY UNION

         On January 1, 1999, the Euro became the official currency of the
European Economic and Monetary Union (the "Union"). Companies in the Union may
begin conducting their business operations in the new currency, however the
previous local currencies in those countries may continue to be used as legal
tender through January 1, 2002.

         The Company has completed its plans and implemented its program to
accommodate the new currency. Software used by the Company at its European
facilities, as well as new software being implemented, is capable of handling
multi-currencies, including the Euro. As such, the Company is able to accept
customer or supplier orders in either the new Euro or the previous local
currency. The Company is addressing the Euro's impact on its operations (e.g.
banking, payroll processing, pricing, currency hedging requirements, etc.) The
estimated costs of required system modifications and other operational changes
are not expected to be material to the Company.
