      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 4 - NEW ACCOUNTING STANDARD

      The Company has adopted Statement of Financial Accounting Standard No.
130, "Reporting Comprehensive Income" effective November 1, 1998. This Statement

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

THREE MONTH PERIOD ENDED APRIL 30, 1999 VS. THREE MONTH PERIOD ENDED APRIL 30,
1998

NET SALES

      The Company had record net sales of $54.0 million in the second quarter of
fiscal 1999 representing a 5.3 percent increase over 1998's second quarter sales
of $51.3 million. Had currency values been unchanged from the second quarter of
fiscal 1998, net sales for the second quarter of 1999 would have been $1.1
million higher, or 7.5 percent greater overall than the comparable period in
fiscal 1998.

      North American sales increased 11.3 percent in the second quarter as
compared to the same quarter in 1998. North American Water Group sales were
responsible for virtually all this growth. The Water Group (within the potable
water market) recently launched a series of new filters designed for appliances
and these products have led the growth within this Group. Second quarter Latin
American sales declined 23.8% percent from the same quarter last year, but
increased 23.5% when expressed in local currency. See "Brazilian Real
Devaluation" below for further details. Sales in Europe were virtually unchanged
as compared to the same period in 1998, and Asia/Pacific sales were up slightly.
Economic conditions continue to be weak in Japan, but certain markets have shown
signs of stabilizing and even strengthening in other parts of Asia over the past
three months.

      The following table displays the Company's sales by market (amounts in
thousands):



                                    THREE MONTHS ENDED                  CURRENCY

                                    =======      =======      ====        ====


      The 31.2 percent increase in Potable Water sales was primarily driven by
volume in North America associated with the aforementioned appliance filters.
The decrease in Fluid Processing sales primarily reflects the continued weakness
in the semiconductor markets as well as a worldwide slowdown in petroleum
exploration and production caused by the recently depressed oil prices. A
decline in sales of the Company's diagnostic membrane products was the primary
reason for the 9.1 percent reduction in Healthcare sales in the second quarter
as compared to the same period last year. Business conditions in the market
remain sound and the decline is not expected to persist beyond the end of the
current fiscal year.

GROSS PROFIT

      The Company's gross profit increased $1.0 million to $23.9 million in the
second quarter of 1999 from $22.9 million in the second quarter of 1998. Gross
profit as a percentage of net sales was relatively flat quarter over quarter
(44.3 percent in 1999 vs. 44.6 percent in 1998). This slight decrease is
attributable to a lower mix of healthcare sales that generally carry a higher
gross margin than sales to


                                      -8-
   11
either the potable water or fluid processing markets as well as the effect of
exporting product from the US for sale in Brazil during the Real's rapid
devaluation. The gross margin increased from 39.2 percent in the fiscal 1999
first quarter.

OPERATING EXPENSES

      Selling, general, and administrative expenses increased by $1.6 million in
the second quarter of 1999 over the second quarter of 1998, representing an 11.6
percent increase. Administrative and selling expenses increased $1.6 million
reflecting the Company's expansion of its sales force, and the timing of certain
employee-related expenses and promotional events. Research, development and
engineering expenses increased 9.4 percent in the second quarter of 1999
reflecting the Company's continued emphasis on the development of new products.

OPERATING INCOME

      As a result of the above, operating income decreased $.8 million, or 13.1
percent, to $5.5 million or 10.2 percent of sales in the second quarter of 1999
as compared to $6.3 million or 12.3 percent of sales in the second quarter of
1998.

NONOPERATING ACTIVITY

      Interest expense was relatively flat ($0.3 million) quarter over quarter
as the level of debt outstanding was also comparable. See "Financial Position
and Liquidity" below. As detailed in Note 5 to the condensed consolidated
financial statements, other income, net was also comparable quarter over quarter
as no material activity occurred in either of the two quarters.

INCOME TAXES

      The Company's effective income tax rate for the second quarter of 1999 was
37.0% compared to 35.0% in the second 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.

SIX MONTH PERIOD ENDED APRIL 30, 1999 VS. SIX MONTH PERIOD ENDED APRIL 30, 1998

NET SALES

      The Company had net sales of $104.7 million in the first six months of
fiscal 1999 representing a 9.8 percent increase over 1998's comparable sales of
$95.3 million. Currency values had a negligible effect on overseas net sales
(period over period) when translated from local currency into US dollars.

      Led by a strong performance in the Water Group, North American sales
increased 18.2 percent in the first six months of 1999 over the comparable
period in 1998. The Water Group's line of appliance filters were especially
successful during this period. Additionally, Chemical Engineering Corporation, a
manufacturer of water treatment equipment which was purchased in March of last
year, was only included in the 1998 results for two months. Latin American sales
declined 14.7 percent during the first six months of 1999 as compared to the
same period last year; however, when stated in local currency, sales increased
18.1%. For a discussion of the currency impact in that region, see "Brazilian
Real Devaluation" below. Sales in Europe and Asia/Pacific were relatively
unchanged during the first six months of the year when compared to the first six
months of last year.

                                    ========     ========     =====       =====


      The 49.3 percent increase in potable water sales was primarily driven by
volume increases associated with the aforementioned appliance filters. The
decrease in Fluid Processing sales is primarily attributed to the continued
slowdown in the electronics and oil & gas industries. The decrease in healthcare
sales is related to an expected temporary decline in the sale of diagnostic
membrane products.

GROSS PROFIT

      The Company's gross profit increased $1.9 million to $43.8 million in the
first six months of 1999 from $41.8 million in the first six months of 1998.
Gross profit as a percentage of net sales decreased to 41.8 percent from 43.9
percent. This decrease was primarily generated in the first quarter of fiscal
1999 and 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.

OPERATING EXPENSES

      Selling, general, and administrative expenses increased by $3.6 million in
the six months of 1999 over the comparable period in 1998, representing a 13.7
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. Additionally, selling expenses increased $2.8
million reflecting the Company's continued expansion of its marketing efforts.
Research, development and engineering expenses increased a moderate 5.3 percent
period over period.

OPERATING INCOME

      As a result of the above, operating income decreased $1.9 million, or 19.1
percent, to $8.2 million or 7.8 percent of sales in the first six months of 1999
as compared to $10.1 million or 10.6 percent of sales in the first six months of
1998.

NONOPERATING ACTIVITY

      Interest expense increased to $0.7 million in the first six months of 1999
from $0.5 million in the first six months 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,
beginning primarily in the second quarter of fiscal year 1998. As detailed in
Note 5 to the condensed consolidated


                                      -10-
   13
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 pre-tax gain of $0.3 million.

INCOME TAXES

      The Company's effective income tax rate for the first six months of 1999
was 36.9% compared to 35.0% in the first six months 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.

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

      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 $1.9 million
reflects the Company's reduced gross profit margin and increased selling,
general and administrative expenses as discussed previously above. Accounts
receivable were reduced $1.3 million during the first six months of 1999 (vs. an
increase of $1.1 million in 1998) due largely to a concentrated effort by
management to improve collections worldwide. Overall, improved management of
accounts receivable, inventory, accounts payable and taxes payable contributed
to the $4.7 million increase in cash


                                      -11-

flow provided by operating activities during the Company's first six months of
1999 compared to the prior year's first six months.

      Capital expenditures amounted to $5.6 million in the first six months of
1999 which were primarily comprised of purchases of machinery and equipment. In
the second quarter of fiscal 1999, the Company made a planned $1.0 million
contingent consideration payment related to the acquisition of Chemical
Engineering Corporation. This payment was recorded as additional goodwill.
During the first six months of fiscal 1998, the Company utilized $9.5 million of
cash to complete the acquisition of Chemical Engineering Corporation and certain
other distribution operations. All of the Company's 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
($9.5 million) in the first six months of 1999, the Company was able to reduce
its long-term debt, on a net basis, by $4.1 million.

OTHER MATTERS

BRAZILIAN REAL DEVALUATION

      CUNO has a subsidiary located in Brazil. A significant devaluation in the
Brazilian Real took place late in the Company's first quarter. Throughout much
of the Company's second quarter, the Real was relatively stable, albeit
substantially weaker relative to the US Dollar as compared to the beginning of
the Company's fiscal year. The Brazilian subsidiary accounted for approximately
7 percent of consolidated net sales in 1998. Although the Brazilian subsidiary
remained profitable during fiscal 1999 and the devaluation had only a minimal
impact on the Company's consolidated results of operations, any future effects
on the business climate in this region are yet to be determined. A significant
portion of the products sold by the subsidiary in Brazil are manufactured
locally - this should continue to help minimize the impact of the devaluation on
future earnings. See "Market Risk Disclosures" below.

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 systems. 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


                                      -12-

in factories and facilities used in the manufacturing process, (3) disruptions
in the supply of raw materials 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 $150,000.

      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 also 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 continues to address 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.
