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

  The following discussion contained should be read in conjunction with the
Company's consolidated financial statements and notes thereto included elsewhere
herein.

GENERAL

  Since July 1991, the Company has acquired and integrated more than 150
businesses with substantial expertise in the design and manufacture of systems
for the filtration and treatment of water and wastewater.  Due to the magnitude
of these acquisitions and the integration of the acquired operations with the
Company's existing businesses, results of operations for prior periods are not
necessarily comparable to or indicative of results of operation for current or
future periods.

Results of Operations

  In December 1997 and June 1998 subsidiaries of the Company merged with and
into Kinetics and Culligan, respectively, in transactions accounted for as
poolings of interests.  Historical consolidated financial data for the fiscal
years ended March 31, 1996 through March 31, 1998 have been restated to reflect
these acquisitions.
 
  The following table sets forth for the periods indicated certain items in the
Selected Consolidated Financial Data as a percentage of total revenues:

TWELVE MONTHS ENDED MARCH 31, 1998 ("FISCAL 1998") COMPARED WITH TWELVE MONTHS
ENDED MARCH 31, 1997 ("FISCAL 1997")

  Revenues

  Revenues for fiscal 1998 were $3.7 billion, an increase of $1.6 billion from
$2.1 billion for the comparable period of the prior fiscal year.  This 75.2%
increase was due primarily to acquisitions completed by the Company after fiscal
1997.  For fiscal 1998 revenues from capital equipment sales represented 42% of
total revenues, while revenues from services and operations represented 22% of
total revenues, revenues from distribution represented 24% of total revenues and
revenues from retail and consumer products represented 12% of total revenues.
The percentage of revenues from capital equipment sales decreased in the current
year due to the Company's emphasis on the recurring revenues of the distribution
business and on the higher margin service business.

  Gross Profit

  Gross profit increased 80.7% to $999.5 million for fiscal 1998 from $553.2
million for the comparable period of the prior fiscal year.  Total gross profit
as a percentage of revenue ("gross margin") was 26.7% for fiscal 1998 compared
to 25.9% for the comparable period of the prior fiscal year.  The increase in
the gross margin can be attributed primarily to the incurrence of certain
unreimbursed project costs at Kinetics during fiscal 1997 after restatement for
the acquisition of Kinetics in the current period accounted for as a pooling of
interests.

  Selling, General and Administrative Expenses

  For fiscal 1998, selling, general, and administrative expenses, excluding
purchased in-process research and development and merger, restructuring,
acquisition and other related charges ("certain charges"), increased $277.6
million to $725.2 million as compared to the $447.6 million in the comparable
period in the prior year.  The increase in these expenses can be attributed
primarily to the addition of sales and administrative personnel accompanying the
Company's acquisitions during the period.  During fiscal 1998, selling, general
and administrative expenses, excluding certain charges, were 19.4% of revenues
compared to 21.0% for the comparable period in the prior year.  The improvement
in selling, general and administrative expenses as a percentage of revenue can
be attributed to certain economies of scale accompanying the Company's and
Culligan's recent acquisitions.

     Purchased In-Process Research and Development

     On December 9, 1997, the Company, through a wholly-owned subsidiary,
completed its tender offer ("Offer") to purchase all of the outstanding ordinary
shares (including American Depository Shares) of Memtec. The purchase price was
$36.00 per share. The Company acquired certain shares in privately negotiated
and open market purchases prior to the Offer resulting in a total cash purchase
price of approximately $397.2 million (including transaction costs of $10.6
million). The purchase price was allocated to the assets and liabilities of
Memtec based on their estimated respective fair values. The Company also
acquired from Memtec certain in-process research and development projects that
had not reached technological feasibility and that had no alternative future
uses. Such projects were valued by an independent appraiser using a risk
adjusted cash flow model under which expected future cash flows were discounted,
taking into account risks related to existing and future markets and assessments
of the life expectancy of such projects. The estimated market value of such in-
process research and development (R&D) projects was $299.5 million and was
expensed at the acquisition date.

  In addition, the Company also acquired from Memtec and its subsidiaries
(consisting of Memcor, Fluid Dynamics, Filterite, and Seitz) developed
technologies including large volume purification product lines; membrane systems
for water purification and waste treatment; metal fiber product lines for
industrial applications involving elevated pressures, temperatures and corrosive
environments; disposable product lines for industrial applications; and depth
media product lines for the pharmaceutical and food and beverage industries.

                                       7
<PAGE>
 
  As a result of the degree of competition in the filtration industry and the
use of technological change as a competitive tool, a significant proportion of
Memtec's technology will be superseded, although the rate of change varies
significantly across the markets addressed. Memtec's R&D initiatives are
therefore targeted at superseding current products. Memtec has a range of
ongoing R&D projects in each of its product lines. Certain of these projects are
directed at next generation products for existing market applications while
others are directed at new market opportunities where Memtec's technological
base may be applicable.

  Memcor R&D projects are primarily directed at enhanced microfiltration
products capable of cost effectively addressing larger scale applications or
more chemically aggressive environments. These R&D projects are at the
laboratory to pilot stage of development and require a number of years of
additional work before full introduction to the market of a product is likely.
Other Memcor R&D projects seek to utilize Memtec's knowledge of electrochemical
processes to enter new markets ranging from high quality water production to
environmental sensors. These R&D projects are also at the laboratory to pilot
stage and similarly require a number of years of additional R&D before a product
may be available for launching.

  Fluid Dynamics R&D projects are directed at developing new applications for
Memtec's proprietary metallic media. The media enables precise fine filtration
in a range of hostile environments as well as having unique conductive
properties. These R&D projects are at the laboratory stage of development and
require additional research ranging from twelve months to several years
depending upon the particular product before any market launch is possible.

  Filterite R&D projects center around its two proprietary technologies--the
unique Filterite highly assymetric membrane and the cold melt spinning
technology. R&D projects are examining expansion of product offerings from these
core technologies. These projects require further materials science laboratory
work followed by manufacturing prototyping and tailoring to market applications-
- -a process which will range from eighteen months to several years.

  Seitz R&D is directed at next generation filtration technologies for the food
and beverage and chemicals industries drawing on the core technologies of Seitz.
These R&D projects are predominantly at the pilot stage, requiring extensive
trialing evaluation and development based on the trialing before market launches
are possible.

  Failure to complete these R&D projects successfully and on time would open the
way for competitors to introduce alternate technologies, with consequent
implications for Memtec's revenues. To be successful in most cases, the R&D
projects must be developed from laboratory or pilot scale models to full scale
products capable of production within a quality accredited manufacturing
process. The existing R&D projects are expected to be completed and
commercialized over the next ten years with expected R&D and project related
expenditures of approximately $275 million over such ten year period. The
expenditures will be expensed or capitalized in accordance with generally
accepted accounting principles.

  The valuation process distinguished between R&D projects with no alternate
uses or values and those with alternate uses. Predominantly all R&D projects are
at a stage of development where the progress to date is not applicable to any
other use within Memtec nor is it saleable to any third party known to
management.

     During fiscal 1998, Culligan wrote-off $36.3 million of in-process research
and development purchased in connection with the acquisition of the Water
Filtration Business.  As of the purchase date, the Water Filtration Business was
engaged in ongoing research and development relating to carbon block extrusion
technology which is less labor intensive than competing technologies, and a new
water filtration product line that is expected to improve the purity of water
and flow rates.  Such projects were valued by an independent appraiser using a
risk adjusted cash flow model under which the expected cash flows were
discounted, taking into account the costs to complete the projects and the life
expectancy of the projects.  Both of these projects are proceeding according to
schedule.  It is estimated that technological and commercial feasibility will be
achieved in 6 to 12 months and that development will not require cash
expenditures that are material to the results of operations or financial
position of the Company.  The principal risk associated with successfully
completing such in-process research and development is that other competitors
may bring technologically superior products to market.  The market growth
potential of acquired in-process research and development is subject to certain
risks, including costs to development and commercialize such products, the cost
and feasibility of production of products utilizing the applicable technologies,
introduction of competing technologies and market acceptance of the products and
technologies involved.  The Company does not believe that the failure to
complete such research 

                                       8
<PAGE>
 
and development projects would have a material adverse effect on its results of
operations or financial position. These technologies are expected to provide an
improvement of approximately 100% in operating margins for these particular
products as compared to overall historic operating margins of the Water
Filtration Business primarily due to anticipated cost reductions. As of the
purchase date, the Water Filtration Business was selling mold process based
water filtration products. These products rely on developed technology and do
not rely on the results of the on-going in-process research and development.
Revenues derived from the Water Filtration Business' current products are
expected to remain constant once the anticipated in-process products are
introduced. Most of the future growth is expected to come from the new products.
The existing technology of the Water Filtration Business acquired is being
amortized over 40 years.

     During fiscal 1998, Culligan wrote-off $19.5 million of in-process research
and development purchased in connection with the acquisition of Protean as these
projects had not reached technological feasibility and had no alternative uses.
As of the purchase date, Elga plc, a subsidiary of Protean, was engaged in the
research and development of a series of new water filtration systems that will
employ new processes or techniques related to the filtration of tap water for
laboratory use.  Such projects were valued by an independent appraiser using a
risk adjusted cash flow model under which the expected cash flows were
discounted, taking into account the cost to completed the projects and the life
expectancy of such projects.  Failure to complete these projects successfully
and on time would open the way for competitors to introduce alternative
technologies, with consequent implications for Elga's revenues.  The projects
are proceeding according to schedule and it is estimated that technological and
commercial feasibility will be met within the existing timeframes which range
from three months to two years.  These projects are not expected to require
future cash expenditures that are material to the results of operations or
financial position of the Company.  The existing technology of Protean is being
amortized over 40 years.

  Merger, Restructuring, Acquisition and Other Related Charges

     As of December 31, 1997, the Company completed the acquisition of Kinetics
in a tax-free reorganization, which was accounted for as a pooling of interests.
Concurrent with the merger with and into Kinetics and the acquisition of Memtec,
the Company designed and implemented a restructuring plan to streamline its
manufacturing and production base, improve efficiency and enhance its
competitiveness. The restructuring plan resulted in a pre-tax charge of $141.1
million. The plan identifies certain products and technologies acquired in
conjunction with the Memtec transaction that supersede products and technologies
acquired in earlier acquisitions of membrane related businesses. As a result
certain carrying amounts of goodwill and other intangible assets were determined
to be impaired by approximately $55.0 million in accordance with Statement of
Financial Accounting Standards No. 121 "Accounting for the Impairment of Long-
Lived Assets and for Long-Lived Assets to be Disposed Of" ("SFAS 121"). SFAS 121
requires that long-lived assets be reviewed for impairment whenever events or
changes in circumstances indicate that the carrying amount of the assets may not
be recoverable. In determining the amount of the impairment of these assets, the
Company valued the assets using the present value of estimated expected future
cash flows using discount rates commensurate with the risks involved. The
restructuring plan also included closing or reconfiguring of certain facilities
and reducing the work force by approximately 350 employees, most of whom work in
the facilities to be closed.

  Included in merger, restructuring, acquisition and other related charges are
the following:

     During fiscal 1998, Culligan recorded a merger and restructuring charge of
$9.5 million in connection with the acquisition of the Water Filtration Business
and as a result of a decision made by the Company to exit the market for the
sale of consumer products in the department store and mass merchant channels so
as to focus principally on the "do-it-yourself" (DIY) and hybrid retail markets.
The merger and restructuring charge reflects the costs of integrating and
streamlining manufacturing, sales, distribution, research and development, and
administrative functions, in order to take advantage of more cost effective
technology acquired in the acquisition of the Water Filtration Business.  The
merger and restructuring charge also reflects costs resulting from the decision
to exit certain retail markets, such as charges against receivables to reflect
the fact that the value of these assets diminished as a result of the decision
to exit portions of the business.  Included in the $9.5 million of merger and
restructuring costs are $0.7 million for severance costs related to the
elimination of redundant employees, $4.3 million for the write-off of inventory,
$1.3 million related to the write-off of receivables, $2.5 million related to
the write-off of excess property, equipment and other assets (consisting
principally of fixed assets used in the manufacture of molded carbon block) and
$0.7 million representing legal and other professional fees.  During fiscal
1998, costs amounting to $4.3 million were charged against the merger and
restructuring reserve.  Total future cash requirements relating to the merger
and restructuring are expected to be immaterial.

  After an income tax benefit of $38.2 million, the charges detailed above
totaling $505.9 million (including purchased in-process research and development
charges totaling $355.3 million and merger, restructuring, acquisition and other
related charges totaling $150.6 million) reduced earnings by $467.7 million.
Approximately $15.4 million of merger and restructuring related charges are
included in accrued liabilities at March 31, 1998. Additional costs to complete
the restructuring plan are not expected to be material.  The write-down of
assets as a result of the restructuring plan (including assets of business'
whose products were superseded by Memtec's products) will not have a material
effect on the Company's consolidated results of operations in the future.

     Operating Income (Loss)

     For fiscal 1998, the Company recorded an operating loss of $231.6 million
as compared to operating income of $100.0 million in the comparable period in
the prior year.  The operating loss can be attributed to the recording of
charges for purchased in-process research and development and merger,
restructuring, acquisition and other related charges as detailed above.  Before
the impact of these charges, operating income for fiscal 1998 was $274.3 million
or 7.3% of revenue.  For fiscal 1997, operating income before merger expenses
was 4.9% of revenues.  The improvement in operating margin before certain
charges can be attributed to improvements in gross margin and selling, general
and administrative expenses as a percent of revenues as described above.

  Interest Expense

  Interest expense increased to $63.8 million for fiscal 1998 from $32.0 million
for the corresponding period in the prior year.  Interest expense for fiscal
1998 consisted primarily of interest on the Company's: (i) 6% Convertible
Subordinated Notes issued on September 18, 1995 due 2005; (ii) 4.5% Convertible
Subordinated Debentures issued on December 11, 1996 due 2001; (iii) borrowings
under Kinetics' long-term line-of-credit; (iv) 8.0% Senior Subordinated
Debentures issued by Kinetics; (v) borrowings under Memtec's long-term line-of-
credit; (vi) Senior Guaranteed Notes issued by Memtec bearing interest at rates
ranging from 7.7% to 8.0%; (viii) other long-term debt bearing interest at rates
ranging from 2.0% to 10.1%: (viii) borrowings under Culligan's credit facility;
and (ix) borrowings under the Company's Senior Credit Facility.  At March 31,
1998, the Company had cash, cash equivalents and short-term investments of $67.2
million.

  Income Tax Expense

  Income tax expense increased to $48.2 million in fiscal 1998 from $30.9
million in the corresponding period in the prior year.  Before certain charges,
the Company had income tax expense of $86.4 million or an effective tax rate of
34.6% for fiscal 1998 as compared to 38.2% in the corresponding period in the
prior year.

  Net Income (Loss)

  For fiscal 1998, income before certain charges increased $109.9 million to
$162.3 million from $52.4 million before certain charges for the same period in
the prior year.  After certain charges, net loss in fiscal 1998 was $305.4
million as compared to net income of $48.4 million for fiscal 1997.  Net income
(loss) per common share for fiscal 1997 and 1998 were as follows:

TWELVE MONTHS ENDED MARCH 31, 1997 ("FISCAL 1997") COMPARED WITH TWELVE MONTHS
ENDED MARCH 31, 1996 ("FISCAL 1996")

     Revenues

     Revenues for fiscal 1997 were $2.1 billion, an increase of $0.7 billion
from $1.4 billion for the comparable period of the prior fiscal year. This 53.0%
increase was due primarily to acquisitions completed by the Company after fiscal
1996. For fiscal 1997, revenues from capital equipment sales represented 48% of
total revenues, while revenues from services and operations represented 20% of
total revenues, revenues from distribution represented 20% of total revenues and
revenues from retail and consumer products represented 12% of total revenues.

     Gross Profit

     Gross profit increased 41.9% to $553.2 million for fiscal 1997 from $389.9
million for the comparable period of the prior fiscal year. Total gross profit
as a percentage of revenue ("gross margin") was 25.9% for fiscal 1997 compared
to 27.9% for the comparable period of the prior fiscal year. The decrease in
gross margin is due primarily to the incurrence of certain unreimbursed project
costs at Kinetics during the fiscal year ended March 31, 1997 after restatement
for the acquisition of Kinetics in the current period accounted for as a pooling
of interests.

     Selling, General and Administrative Expenses

     For fiscal 1997, selling, general, and administrative expenses, excluding
merger expenses, increased $120.7 million to $447.6 million as compared to the
$326.9 million in the comparable period in the prior year. The increase in these
expenses can be attributed primarily to the addition of sales and administrative
personnel accompanying the Company's acquisitions after fiscal 1996.  During
fiscal 1997, selling, general and administrative expenses, excluding Davis
merger expenses, were 21.0% of revenues compared to 23.4% for the comparable
period in the prior year. The decrease is due primarily to substantially lower
amortization of intangible assets at Culligan during fiscal 1997.  The lower
amortization was offset partially by Kinetics recording certain charges in
selling, general and administrative expenses during the fiscal year ended March
31, 1997 for the write-off of certain receivables, the write-down of certain
assets, the increase in Kinetics' allowance for doubtful accounts and the
establishment of certain accruals. These charges are included in fiscal 1997
after restatement for the acquisition of Kinetics in the current period
accounted for as a pooling of interests.

     Excluding Davis merger expenses, operating income as a percentage of
revenues increased to 4.9% for fiscal 1997 from 4.5% for the corresponding
period in fiscal 1996 due to the improvement in selling, general and
administrative as a percentage of revenue as described above.

<PAGE>
 
     Merger Expenses

     Merger expenses were incurred during fiscal 1997 relating to the Company's
acquisition of Davis which was accounted for as a pooling of interests. These
merger expenses, which totaled $5.6 million, consisted primarily of investment
banking fees, printing, stock transfer fees, legal fees, accounting fees,
governmental filing fees and certain other costs related to existing Davis
pension plans and change of control payments.

     Interest Expense

     Interest expense increased to $32.0 million for fiscal 1997 from $28.7
million for the corresponding period in the prior year.  Interest expense for
fiscal 1997 consisted primarily of interest on the Company's: (i) 5% Convertible
Debentures due 2000 (all of which were, as of October 25, 1996, converted into
shares of Common Stock); (ii) 6% Convertible Subordinated Notes due 2005 issued
on September 18, 1995; (iii) 4.5% Convertible Subordinated Debentures due 2001
issued on December 11, 1996; (iv) 8% Senior Subordinated Notes issued by
Kinetics; (v) borrowings under Culligan's line of credit; (vi) borrowings under
the Company's bank line of credit; and (vii) borrowings under Kinetics' line of
credit.  At March 31, 1997, the Company had cash, cash equivalents and short-
term investments of $146.3 million.

     Income Tax Expense

     Income tax expense decreased to $30.9 million in fiscal 1997 from $35.2
million in the corresponding period in the prior year. The Company's effective
tax rate, after merger expenses, for fiscal 1997 was 39.0% as compared to 78.9%
in the corresponding period in the prior year. At March 31, 1997, the Company
had net operating loss carryforwards of approximately $16.4 million in France
for which financial statement benefit was recognized in fiscal 1997.

     Net Income

     For fiscal 1997, net income increased $39.0 million to $48.4 million from
$9.4 million for the same period in the prior year.

LIQUIDITY AND CAPITAL RESOURCES

  The Company's principal sources of funds are cash and other working capital,
cash flow generated from operations and borrowings under the Company's Senior
Credit Facility. At March 31, 1998, the Company had working capital of $704.4
million including cash and short-term investments of $67.2 million. The
Company's long-term debt at March 31, 1998, was $554.0 million consisting of
$140.0 million of 6.0% Convertible Subordinated Notes due 2005 and $414.0
million of 4.5% Convertible Subordinated Notes due 2001. The Company also had
other long-term debt totaling $523.3 million bearing interest at rates ranging
from 2.0% to 10.1%.

  As of March 31, 1998, the Company had a Senior Credit Facility which provides
credit facilities to the Company of up to $750.0 million, of which there were
outstanding borrowings of $574.8 million and outstanding letters of credit of
$40.7 million. Borrowings under the Senior Credit Facility bear interest at
variable rates of up to 0.45% above certain Eurocurrency rates or 0.15% above
BankBoston's base rate. The Senior Credit Facility is subject to customary and
usual terms.

  In connection with the acquisitions of Kinetics, Memtec and Culligan, the
Company assumed three additional loan agreements with banks. One agreement
provides a revolving line-of-credit with borrowings of up to $100.0 million, of
which no amounts were outstanding at March 31, 1998.  Borrowings under this
agreement bear interest at the bank's reference rate or other interest rate
options that the subsidiary may select. The second agreement is a Multi-Option,
Multi-Currency Master Facility that provides borrowings of up to $60.0 million,
of which $30.7 million was outstanding as of March 31, 1998. Borrowings under
this agreement bear interest at LIBOR plus 0.75%.  The third agreement is a $300
million multi-currency revolving credit facility (the "Culligan Credit
Facility"), of which $287.8 million was outstanding at March 31, 1998.
Borrowings under the Culligan Credit 

                                       12
<PAGE>
 
Facility bear interest at the bank's prime rate or other interest rate options
that a subsidiary may select. The Company anticipates that it will terminate all
three of these agreements during fiscal 1999.

     Subsequent to the Company's fiscal year end, on May 15, 1998, the Company
issued $500 million 6.375% Remarketable or Redeemable Securities due 2011
(Remarketing Date May 15, 2001) and $400 million 6.50% Remarketable or
Redeemable Securities due 2013 (Remarketing Date May 15, 2003) (collectively,
the "ROARS").  The net proceeds from the sale of the ROARS, including a premium
payment to the Company by NationsBanc Montgomery Securities LLC, were $913.6
million.  The net proceeds were used to repay indebtedness outstanding under the
Senior Credit Facility, indebtedness assumed in the acquisition of Memtec, and a
portion of the indebtedness assumed in the acquisition of Culligan.

  The Company believes its current cash position, cash flow from operations, and
available borrowings under the Company's line-of-credit will be adequate to meet
its anticipated cash needs from working capital, revenue growth, scheduled debt
repayment and capital investment objectives for at least the next twelve months.


CERTAIN TRENDS AND UNCERTAINTIES
 
  The Company and its representatives may from time to time make written or oral
forward-looking statements, including statements contained in the Company's
filings with the United States Securities and Exchange Commission and in its
reports to stockholders.  In connection with the "Safe Harbor" provisions of the
Private Securities Litigation Reform Act of 1995, the Company is hereby
identifying important factors that could cause actual results to differ
materially from those contained in any forward-looking statement made by or on
behalf of the Company; any such statement is qualified by reference to the
following cautionary statements.

Acquisition Strategy. In pursuit of its strategic objective of becoming the
leading global single-source provider of water and wastewater treatment systems
and services, the Company has, since 1991, acquired more than 150 United States
based and international businesses.  The Company plans to continue to pursue
acquisitions that expand the segments of the water and wastewater treatment and
water-related industries in which it participates, complement its technologies,
products or services, broaden its customer base and geographic areas served
and/or expand its global distribution network, as well as acquisitions which
provide opportunities to further and implement the Company's one-stop-shop
approach in terms of technology, distribution or service.  The Company's
acquisition strategy entails the potential risks inherent in assessing the
value, strengths, weaknesses, contingent or other liabilities and potential
profitability of acquisition candidates and in integrating the operations of
acquired companies.  In addition, the Company's acquisition of Memtec was
accomplished through an unsolicited tender offer, and the Company could make
other such acquisitions.  The level of risk associated with such acquisitions is
generally greater because frequently they are accomplished, as was the case with
the acquisition of Memtec, without the customary representations or due
diligence typical of negotiated transactions.  Although the Company generally
has been successful in pursuing acquisitions, there can be no assurance that
acquisition opportunities will continue to be available, that the Company will
have access to the capital required to finance potential acquisitions, that the
Company will continue to acquire businesses or that any business acquired will
be integrated successfully or prove profitable.


International Transactions. The Company has made and expects it will continue to
make acquisitions and expects to obtain contracts in markets outside the United
States.  While these activities may provide important opportunities for the
Company to offer its products and services internationally, they also entail the
risks associated with conducting business internationally, including the risk of
currency fluctuations, slower payment of invoices, the lack in some
jurisdictions of well-developed legal systems, nationalization and possible
social, political and economic instability.  In particular, the Company has
significant operations in Asia and Latin America which have been and may in the
future be adversely affected by current economic conditions in those regions.
While the full impact of this economic instability cannot be predicted, it could
have a material adverse effect on the Company's revenues and profitability.

                                       13
<PAGE>
 
Reliance on Key Personnel.   The operations of the Company are dependent on the
continued efforts of senior management, in particular Richard J. Heckmann, the
Company's Chairman of the Board, President and Chief Executive Officer.  The
Company has entered into various agreements and compensation arrangements with
certain members of its senior management, including Mr. Heckmann, designed to
encourage their retention.  There can be no assurance, however, that members of
the Company's senior management will continue in their present roles, and should
any of the Company's senior managers be unable or choose not to do so, the
Company's prospects could be adversely affected.


Profitability of Fixed Price Contracts.   A significant portion of the Company's
revenues are generated under fixed price contracts.  To the extent that original
cost estimates are inaccurate, scheduled deliveries are delayed or progress
under a contract is otherwise impeded, revenue recognition and profitability
from a particular contract may be adversely affected.  The Company routinely
records upward or downward adjustments with respect to fixed price contracts due
to changes in estimates of costs to complete such contracts.  There can be no
assurance that future downward adjustments will not be material.

Cyclicality, Seasonality and Possible Earnings Fluctuations.   The sale of
capital equipment within the water treatment industry is cyclical and influenced
by various economic factors including interest rates and general fluctuations of
the business cycle.  A significant portion of the Company's revenues are derived
from capital equipment sales.  While the Company sells capital equipment to
customers in diverse industries and in global markets, cyclicality of capital
equipment sales and instability of general economic conditions, including those
currently unfolding in Asian and certain other markets markets, could have a
material adverse effect on the Company's revenues and profitability.

      The sale of water and wastewater distribution equipment and supplies is
also cyclical and influenced by various economic factors including interest
rates, land development and housing construction industry cycles. Sales of such
equipment and supplies are also subject to seasonal fluctuation in temperate
climates. The sale of water and wastewater distribution equipment and supplies
is a significant component of the Company's business. Cyclicality and
seasonality of water and wastewater distribution equipment and supplies sales
could have a material adverse effect on the Company's revenues and
profitability.

  The Company's high-purity process piping systems have been sold principally to
companies in the semiconductor and, to a lesser extent, pharmaceutical and
biotechnology industries, and sales of those systems are critically dependent on
these industries.  The success of customers and potential customers for high-
purity process piping systems is linked to economic conditions in these
respective industries, which in turn are each subject to intense competitive
pressure and are affected by overall economic conditions.  The semiconductor
industry in particular has historically been, and will likely continue to be,
cyclical in nature and vulnerable to general downturns in the economy.  The
semiconductor and pharmaceutical industries also represent significant markets
for the Company's water and wastewater treatment systems.  Downturns in these
industries could have a material adverse effect on the Company's revenues and
profitability.

  Operating results from the sale of high-purity process piping systems also can
be expected to fluctuate significantly as a result of the limited pool of
existing and potential customers for these systems, the timing of new contracts,
possible deferrals or cancellations of existing contracts and the evolving and
unpredictable nature of the markets for high-purity process piping systems.

  As a result of these and other factors, the Company's operating results may be
subject to quarterly or annual fluctuations.  There can be no assurance that at
any given time the Company's operating results will meet or exceed stock market
analysts' expectations.

Potential Environmental Risks. The Company's business and products may be
significantly influenced by the constantly changing body of environmental laws
and regulations, which require that certain environmental standards be met and
impose liability for the failure to comply with such standards.  The Company is
also subject to inherent risks associated with environmental conditions 

                                       14
<PAGE>
 
at facilities owned, and the state of compliance with environmental laws by
businesses acquired, by the Company.  While the Company endeavors at each of its
facilities to assure compliance with environmental laws and regulations, there
can be no assurance that the Company's operations or activities, or historical
operations by others at the Company's locations, will not result in cleanup
obligations, civil or criminal enforcement actions or private actions that could
have a material adverse effect on the Company.

  In that regard, at a Connecticut ion exchange resin regeneration facility (the
"South Windsor Facility") operated by a wholly owned subsidiary of the Company
(the "South Windsor Subsidiary"), acquired by the Company in October 1995 from
Anjou International Company ("Anjou"), U.S. federal and state environmental
regulatory authorities have issued certain notices of violation alleging
multiple violations of applicable wastewater pretreatment standards.  The South
Windsor Subsidiary reached an agreement with the U.S. Attorney's Office and the
U.S. Environmental Protection Agency ("USEPA") to settle all agency claims and
investigations relating to this matter by entering into a plea agreement
pursuant to which the South Windsor Subsidiary will plead guilty to a single
violation of the Clean Water Act.  The settlement includes a payment of $1.36
million, including a criminal penalty of  $1.0 million, and annual environmental
compliance audits at the South Windsor Facility for five years.  The Company
believes that this settlement will conclude this matter in its entirety;
however, the settlement does not include a formal release of all liabilities in
this regard.  The Company has certain rights of indemnification from Anjou which
may be available with respect to this matter pursuant to the laws of the state
of New York or the Stock Purchase Agreement dated as of August 30, 1995 among
the Company, Anjou and Polymetrics, Inc.

  In 1995, Culligan purchased an equity interest in Anvil Holdings, Inc.
("Anvil"). As a result of this transaction, Culligan assumed certain
environmental liabilities associated with soil and groundwater contamination at
Anvil Knitwear's Asheville Dyeing and Finishing Plant (the "Plant") in
Swannanoa, North Carolina. Since 1990, Culligan and Anvil have delineated and
monitored the contamination pursuant to an Administrative Consent Order entered
into with the North Carolina Department of Environment, Health and Natural
Resources related to the closure of an underground storage tank at the site.
Groundwater testing at the Plant and at two adjoining properties has shown
levels of a cleaning solvent believed to be from the Plant that are above action
levels under state guidelines. The Company has begun remediation of the
contamination. The Company currently estimates that the costs of future site
remediation will range from $1.0 million to $1.8 million and that it has
sufficient reserves for the site cleanup. The Company anticipates that the
potential costs of further monitoring and corrective measures to address the
groundwater problem under applicable laws will not have a material adverse
effect on the financial position or the results of operations of the Company.
However, because the full extent of the required cleanup has not been
determined, there can be no assurance that this matter will not have a material
adverse effect on the Company's financial position or results of operations.

  The Company's activities as owner and operator of certain hazardous waste
treatment and recovery facilities are subject to stringent laws and regulations
and compliance reviews. Failure of these facilities to comply with those
regulations could result in substantial fines and the suspension or revocation
of the facility's hazardous waste permit. The Company serves as contract
operator of various municipal and industrial wastewater collection and treatment
facilities, which were developed and are owned by governmental or private
entities. The Company also operates other facilities, including service
deionization centers and manufacturing facilities, that discharge wastewater in
connection with routine operations. Under certain service contracts and
applicable environmental laws, the Company as operator of such facilities may
incur certain liabilities in the event those facilities experience malfunctions
or discharge wastewater which does not meet applicable permit limits and
regulatory requirements. In some cases, the potential for such liabilities
depends upon design or operational conditions over which the Company has
limited, if any, control.

  Certain of the Company's facilities contain or in the past contained
underground storage tanks which may have caused soil or groundwater
contamination.  At one site formerly owned by Culligan, the Company is
investigating, and has taken certain actions to correct, contamination that may
have resulted from a former underground storage tank.  Based on the amount of
contamination believed to have been present when the tank was removed, and the
probability that some of the contamination may have originated from nearby
properties, the Company believes, although there can be no assurance, that this
matter will not have a material adverse effect on the Company's financial
position or results of operations.

                                       15
<PAGE>
 
  In other matters, the Company has been notified by the USEPA that it is a
potentially responsible party under the Comprehensive Environmental Response,
Compensation, and Liability Act of 1980 ("CERCLA") at certain sites to which the
Company or its predecessors allegedly sent waste in the past.  It is possible
that the Company could receive other such notices under CERCLA or analogous
state laws in the future.  Based on sites which are currently known to the
Company that may require remediation, the Company does not believe that its
liability, if any, relating to such sites will be material. However, there can
be no assurance that such matters will not be material.  In addition, to some
extent, the liabilities and risks imposed by environmental laws on the Company's
customers may adversely impact demand for certain of the Company's products or
services or impose greater liabilities and risks on the Company, which could
also have an adverse effect on the Company's competitive and financial position.

Competition All of the markets in which the Company competes are highly
competitive, and most are fragmented, with numerous regional and local
participants.  There are competitors of the Company in certain markets that are
divisions or subsidiaries of companies that have significantly greater resources
than the Company.  The Company's process water treatment business competes in
the United States and internationally principally on the basis of product
quality and specifications, technology, reliability, price, customized design
and technical qualifications, reputation and prompt availability of local
service.  The Company's wastewater treatment business competes in the United
States and internationally largely on the basis of the same factors, except that
pricing considerations can be predominant among competitors that have sufficient
technical qualifications, particularly in the municipal contract bid process.
The Company's filtration and separation business competes in the United States
and internationally principally on the basis of price, technical expertise,
product quality and responsiveness to customer needs, including service and
technical support.  The Company's industrial products and services business
competes in the United States and internationally principally on the basis of
quality, service and price.  In connection with the marketing of waterworks
distribution equipment and supplies, the Company competes not only with a large
number of independent wholesalers and with other distribution chains similar to
the Company, but also with manufacturers who sell directly to customers.  The
principal methods of competition for the Company's waterworks distribution
business include prompt local service capability, product knowledge by the sales
force and service branch management, and price.  The Company's consumer products
business competes with companies with national distribution networks, businesses
with regional scope, and local product assemblers or service companies, as well
as retail outlets.  The Company believes that there are thousands of
participants in the residential water business.  The consumer products business
competes principally on the basis of price, product quality and "taste,"
service, distribution capabilities, geographic presence and reputation.
Competitive pressures, including those described above, and other factors could
cause the Company to lose market share or could result in significant price
erosion, either of which could have a material adverse effect upon the Company's
financial position, results of operations and cash flows.

Potential Risks Related to Water Rights and Water Transfers. The Company owns
more than 47,000 acres of agricultural land (the "Properties"), situated in the
Southwestern United States, the substantial majority of which are in Imperial
County, California (the "IID Properties") located within the Imperial Irrigation
District (the "IID").  Substantially all of the Properties are currently leased
to third party agricultural tenants, including prior owners of the Properties.
The Company acquired the Properties with appurtenant water rights, and is
actively seeking to acquire additional properties with water rights, primarily
in the Southwestern and Western United States.  The Company may seek in the
future to transfer water attributable to water rights appurtenant to the
Properties, particularly the IID Properties (the "IID Water").  However, since
the IID holds title to all of the water rights within the IID in trust for the
landowners, the IID would control the timing and terms of any transfers of IID
Water by the Company.  The circumstances under which transfers of water can be
made and the profitability of any transfers are subject to significant
uncertainties, including hydrologic risks of variable water supplies, risks
presented by allocations of water under existing and prospective priorities, and
risks of adverse changes to or interpretations of U.S. federal, state and local
laws, regulations and policies.  Transfers of IID Water attributable to water
rights appurtenant to the IID Properties (the "IID Water Rights") are subject to
additional uncertainties.  Allocations of Colorado River water, which is the
source of all water deliveries to the IID Properties, are subject to limitations
under complex international treaties, interstate compacts, U.S. federal and
state laws and regulations, and contractual arrangements and, in times of
drought, water deliveries could be curtailed by the U.S. government.  Further,
any transfers of IID Water would require the approval of the U.S. Secretary of
the Interior.  Even if a transfer were approved, other California water
districts and users could assert claims adverse to the IID Water Rights,
including but not limited to claims that the IID has failed to satisfy U.S.
federal law and California constitutional requirements that IID Water must be
put to reasonable and 

                                       16

beneficial use. A finding that the IID's water use is unreasonable or
nonbeneficial could adversely impact title to the IID Water Rights and the
ability to transfer IID Water. Water transferred by the IID to metropolitan
areas of Southern California, such as San Diego, currently would be transported
through aqueducts owned or controlled by the Metropolitan Water District, a
quasi-governmental agency (the "MWD"). The transportation cost for any transfer
of IID Water and the volume of water which the MWD can be required to transport
at any time are subject to California laws of uncertain application, some
aspects of which are currently in litigation. The uncertainties associated with
water rights could have a material adverse effect on the Company's future
profitability.

Technological and Regulatory Risks. Portions of the water and wastewater
treatment business are characterized by changing technology, competitively
imposed process standards and regulatory requirements, each of which influences
the demand for the Company's products and services.  Changes in regulatory or
industrial requirements may render certain of the Company's treatment products
and processes obsolete.  Acceptance of new products may also be affected by the
adoption of new government regulations requiring stricter standards.  The
Company's ability to anticipate changes in technological and regulatory
standards and to develop successfully and introduce new and enhanced products on
a timely basis will be a significant factor in the Company's ability to grow and
to remain competitive.  There can be no assurance that the Company will be able
to achieve the technological advances that may be necessary for it to remain
competitive or that certain of its products will not become obsolete.  In
addition, the Company is subject to the risks generally associated with new
product introductions and applications, including lack of market acceptance,
delays in development or failure of products to operate properly.  The market
growth potential of acquired in-process research and development is subject to
certain risks, including costs to develop and commercialize such products, the
cost and feasibility of production of products utilizing the applicable
technologies, introduction of competing technologies and market acceptance of
the products and technologies involved.

There can be no assurance that the Company's existing or any future trademarks
or patents will be enforceable or will provide substantial protection from
competition or be of commercial benefit to the Company.  In addition, the laws
of certain non-United States countries may not protect proprietary rights to the
same extent as do the laws of the United States.  Successful challenges to
certain of the Company's patents or trademarks could materially adversely affect
its competitive and financial position.

Municipal Water and Wastewater Business.   A significant percentage of the
Company's revenues is derived from municipal customers.  While municipalities
represent an important part of the water and wastewater treatment industry,
contractor selection processes and funding for projects in the municipal sector
entail certain additional risks not typically encountered with industrial
customers.  Competition for selection of a municipal contractor typically occurs
through a formal bidding process which can require the commitment of resources
and greater lead times than industrial projects.  In addition, this segment is
dependent upon the availability of funding at the local level, which may be the
subject of increasing pressure as local governments are expected to bear a
greater share of the cost of public services.

Year 2000 Risks.  

  The Year 2000 issue concerns the potential exposures related to the automated
generation of business and financial misinformation resulting from the
application of computer programs which have been written using six digits (e.g.,
12/31/99), rather than eight (e.g., 12/31/1999), to define the applicable year 
of business transactions.  The Company is currently identifying which of its 
information technology ("IT") and non-IT systems will be affected by Year 2000 
issues.  Most of the Company's IT systems with Year 2000 issues have been 
modified to address those issues.  The Company has also commenced identification
and assessment of its broad range of non-IT systems, which include, among other 
things, components found in the Company's water and wastewater treatment plants,
process water treatment systems and hazardous waste treatment facilities 
operated and/or owned under contract by the Company, as well as components found
in equipment in the Company's manufacturing facilities.

                                      17

  The Company's Year 2000 compliance program consists of three phases: 
identification and assessment; remediation; and testing.  For any given system,
the phases occur in sequential order, from identification and assessment of Year
2000 problems, to remediation, and, finally, to testing the Company's solutions.
However, as the Company acquires additional businesses, each IT and non-IT 
system of the acquired business must be independently identified and assessed.  
As a result, all three phases of the Company's Year 2000 compliance program may 
be occurring simultaneously as they relate to different systems, with varying 
timetables to completion, depending upon the system and the date when a 
particular business was acquired by the Company.

  The Company has completed the identification and assessment of most of its IT 
systems, and those systems have been modified to address Year 2000 problems.  
The Company will continue to assess the systems of those businesses that it has 
recently acquired and those businesses that it may acquire in the future.  The 
Company is in the identification and assessment phase with respect to all non-IT
systems, which is projected to continue until September 1999 for currently-owned
businesses.  Once the Company's systems are assessed for Year 2000 issues, the 
remediation phase will begin, followed by the testing phase.  All phases are 
expected to be completed by mid-1999, although there can be no assurance that 
all phases for all businesses will be completed by that date.  In particular, 
there can be no assurance that acquired businesses will be Year 2000 compliant, 
although the Company currently has a policy for acquisitions of businesses that 
requires a candidate for acquisition to represent and warrant to the Company 
that such business is Year 2000 compliant.  In addition to its internal systems,
the Company has begun to assess the level of Year 2000 problems associated with 
various suppliers, customers and creditors of the Company.  To test the Year 
2000 compliance status of its suppliers, the Company is in the process of 
submitting hypothetical orders to its suppliers dated after December 31, 1999 
and requesting confirmation that the orders have been correctly processed.  The 
Company's costs to date for its Year 2000 compliance program, excluding the 
salaries of its employees, has not been material.  Although the Company has not 
completed its assessment, it does not currently believe that the future costs 
associated with its Year 2000 compliance program will be material.

  The Company is currently unable to determine the most reasonably likely worst 
case scenario as it has not identified and assessed all of its systems, 
particularly its non-IT systems.  As the Company completes its identification 
and assessment of internal and third-party systems, it will develop contingency 
plans for various worst case scenarios.  The Company expects to have such 
contingency plans in place by September 1999.  A failure to address Year 2000 
issues successfully could have a material adverse effect on the Company's 
business, financial condition or results of operations.

  Impact of Recently Issued Accounting Standards. In June 1997, FASB issued a
new statement titled "Disclosures about Segments of an Enterprise and Related
Information". The new statement is effective for fiscal years beginning after
December 15, 1997.  The Company is currently determining required disclosure
under this new standard and will include the disclosures in its next annual
report.

In June 1998, FASB issued a new statement titled "Accounting for Derivative
Instruments and Hedging Activities.  The new statement is effective for fiscal
years beginning after June 15, 1999.  The Company does not believe that the
adoption of this standard will have a material impact on its consolidated
financial position or results of operations.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders
United States Filter Corporation:


     We have audited the accompanying consolidated balance sheets of United
States Filter Corporation and subsidiaries as of March 31, 1997 and 1998, and
the related consolidated statements of operations, shareholders' equity, and
cash flows for each of the years in the three-year period ended March 31, 1998.
These consolidated financial statements are the responsibility of the Company's
management.  Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.  We did not audit the consolidated
financial statements of The Kinetics Group, Inc., a wholly owned subsidiary, as
of March 31, 1997, which statements reflect total assets constituting 6 percent
in 1997, and total revenues constituting 20 percent and 18 percent in 1996 and
1997, respectively, of the related consolidated totals.  Those consolidated
financial statements were audited by other auditors whose report has been
furnished to us, and our opinion, insofar as it relates to the amounts included
for The Kinetics Group, Inc., is based solely  on the report of the auditors.

     We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, based on our audits and the report of the other auditors,
the consolidated financial statements referred to above present fairly, in all
material respects, the financial position of United States Filter Corporation
and subsidiaries as of March 31, 1997 and 1998, and the results of their
operations and their cash flows for each of the years in the three-year period
ended March 31, 1998, in conformity with generally accepted accounting
principles.

                                AND SUBSIDIARIES

                   Notes to Consolidated Financial Statements

                   Years ended March 31, 1996, 1997 and 1998

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the financial statements of
   United States Filter Corporation and wholly owned subsidiaries (the
   "Company").  All significant intercompany accounts and transactions have been
   eliminated in consolidation.

   REVENUE RECOGNITION

     Method of Accounting for Contracts

     The accounting records of the Company are maintained and income is reported
   for financial reporting and income tax purposes for long-term contracts under
   the percentage-of-completion method of accounting.  Under this method, an
   estimated percentage for each contract, based on the cost of work performed
   to date that has contributed to contract performance compared to the
   estimated cost, is applied to contract price and recognized as revenue.
   Provision is made for the entire amount of future estimated losses on
   contracts in progress in the period such losses are determined.  Claims for
   additional contract compensation due the Company are not reflected in the
   accounts until the year in which such claims are allowed, except where
   contract terms specifically provide for certain claims.

     Contract costs include all direct material and labor and indirect costs
   related to contract performance.  General and administrative expenses are
   charged to expense as incurred.

     Products and Services

     Sales of other products and services are recorded as products are shipped
   or services rendered.

   INCOME TAXES

     Deferred tax liabilities and assets are determined based on the difference
   between the financial statement and tax bases of assets and liabilities using
   tax rates in effect for the year in which the differences are expected to
   reverse.

     United States income taxes are not provided on the undistributed earnings
   of its non-U.S. subsidiaries as such earnings are intended to be indefinitely
   reinvested in those operations.

   FOREIGN CURRENCY TRANSLATION

     Assets and liabilities denominated in a functional currency other than U.S.
   dollars are translated into U.S. dollars at the current rate of exchange
   existing at period-end and revenues and expenses are translated at the
   average monthly exchange rates.  Translation adjustments are included as a
   separate component of shareholders' equity. Transaction gains and losses
   included in net income (loss) are immaterial.  The effects of exchange rate
   changes on cash are immaterial as of March 31, 1997 and 1998 and for each of
   the years in the three year period ended March 31, 1998.

   INVENTORIES

     Inventories are stated at the lower of cost or market.  Cost is determined
     using the first-in, first-out method.

                       UNITED STATES FILTER CORPORATION

                               AND SUBSIDIARIES

            Notes to Consolidated Financial Statements (Continued)

   PROPERTY, PLANT AND EQUIPMENT

     Property, plant and equipment are stated at cost and depreciated on the
   straight-line method over the estimated useful lives of the respective assets
   which range from three to 40 years.  Leasehold improvements are amortized on
   the straight-line method over the lesser of their estimated useful lives or
   the related lease term.

   COSTS IN EXCESS OF NET ASSETS OF BUSINESSES ACQUIRED

     Costs in excess of net assets of businesses acquired are amortized on the
   straight-line method over a 20- to 40-year life.  The Company evaluates the
   recoverability of these costs based upon expectations of non-discounted cash
   flows of each subsidiary.

   INVESTMENTS IN UNCONSOLIDATED JOINT VENTURES

     Investments in unconsolidated joint ventures are accounted for using the
   equity method.  The Company's share of earnings or losses from these joint
   ventures is reflected in income and dividends are credited against the
   investment when received.

   NET UNAMORTIZED DEBT ISSUANCE COSTS

     Net unamortized debt issuance costs, aggregating $16.9 million and $11.2
   million at March 31, 1997 and 1998, respectively, have been deferred and are
   being amortized over the term of the related debt ranging from five to ten
   years.

   WARRANTIES

     The Company`s products are generally warrantied against defects in material
   and workmanship for a period of one year.  The Company has accrued for
   estimated future warranty costs.

   ENVIRONMENTAL EXPENDITURES

             Expenditures for environmental protection are expensed or
   capitalized, as appropriate.  Costs associated with remediation activities
   are expensed.  Liabilities are recorded when remedial efforts are probable
   and the costs can be reasonably estimated.

   ADVERTISING

     Costs incurred for advertising, including costs incurred under the
   Company's U.S. cooperative advertising program with its dealers and
   franchisees, are expensed when incurred.

   USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
   accepted accounting principles requires management to make estimates and
   assumptions that affect the reported amounts of assets and liabilities and
   disclosure of contingent assets and liabilities at the date of the financial
   statements and the reported amounts of revenues and expenses during the
   reporting period.  Actual results could differ from those estimates.

   FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts of cash and cash equivalents, short-term investments,
   accounts receivable, accounts payable, and accrued liabilities approximate
   fair value because of the short maturity of these instruments.  The carrying
   amount of the Company's revolving credit facility approximates its fair value
   because the interest rate on the instrument changes with market interest
   rates.  The fair value of the Company's long-term debt (including current
   portion) is estimated to be equal to the carrying amounts based on quoted
   market prices for similar issues or on the current rates offered to the
   Company for debt of the same remaining maturities.

   INCOME (LOSS) PER COMMON SHARE

     Income (loss) per common share is computed based on the weighted average
   number of shares outstanding and in accordance with Statement of Financial
   Accounting Standards ("SFAS") No. 128 "Earnings Per Share". Dilutive
   securities consisting of convertible preferred stock, convertible
   subordinated debt and common stock options are included in the computation of
   income (loss) per diluted share when their effect is dilutive. Accordingly,
   "Basic EPS" and "Diluted EPS" were calculated as follows:

- -------------------
*    The calculation of Diluted EPS for the years ended March 31, 1996, 1997 and
     1998 does not assume conversion of subordinated debt as its effect would be
     antidilutive to income (loss) per common share.

**   The calculation of Diluted EPS for the year ended March 31, 1998 does not
     assume the exercise of options as the effect would be antidilutive to loss
     per common share.  Under the treasury stock method, the exercise of all
     outstanding options would have increased the weighted average number of
     shares by 2,449,000 for the year ended March 31, 1998.

***  On March 4, 1996, the preferred shareholder tendered its Series A Preferred
     Stock for conversion into Company common stock thus eliminating further
     dividends.

(9) ACQUISITIONS

     Acquisitions  Accounted for as Poolings of Interests
     ----------------------------------------------------

     As of December 31, 1997, a wholly-owned subsidiary of the Company completed
    the acquisition of The Kinetics Group, Inc. ("Kinetics") in a tax-free
    reorganization. In connection with the acquisition, the Company issued
    5,803,803 shares of the Company's common stock for all of the outstanding
    common stock of Kinetics (0.5824 share of the Company's common stock for
    each outstanding share and each outstanding option or other right to acquire
    a share of Kinetics common stock). In addition, the Company assumed
    approximately $50.0 million of third party institutional debt.

     Kinetics, based in Santa Clara, California, is a provider and manufacturer
    of sophisticated high-purity process piping systems and is also a leading
    integrator in the United States of high purity water, fluid and gas handling
    systems that are critical to the pharmaceutical, biotechnology and micro
    electronics industries.

     This transaction has been accounted for as a pooling of interests and,
    accordingly, the consolidated financial statements and notes thereto for all
    periods presented have been restated to include the accounts of Kinetics. In
    restating the Company's historical financial statements for the pooling of
    interests with Kinetics, the Company's balance sheet as of March 31, 1997

            Notes to Consolidated Financial Statements (Continued)
 
   was combined with Kinetics audited balance sheet as of September 30, 1997.
   The results of the Company for the fiscal year ended March 31, 1997 were
   combined with historical results of Kinetics for the year ended September 30,
   1997; historical results of the Company for the year ended March 31, 1996
   were combined with historical results of Kinetics for the year ended
   September 30, 1996. Accordingly, results of Kinetics for the six month period
   ended September 30, 1995 (including revenue of $106.9 million and a net
   income of $2.8 million) are not included in the combined results of
   operations presented herein. Concurrent with the Company's merger, Kinetics
   year end was recast to March 31. Accordingly, results of Kinetics for the six
   month period ended September 30, 1997 (including revenue of $227.4 million
   and a net loss of $8.5 million) are included in both the restated historical
   results for the year ended March 31, 1997 and the results for the year ended
   March 31, 1998. Merger expenses incurred to consummate the Kinetics
   transaction totaled $4.3 million consisting of investment banking, printing,
   stock transfer, legal, accounting and governmental filing fees as well as
   certain other transaction costs and are included in merger, restructuring,
   acquisition and other related charges in the accompanying consolidated
   statement of operations for the year ended March 31, 1998.

   Subsequent to the Company's year end, on June 15, 1998, a wholly owned
   subsidiary of the Company and Culligan Water Technologies, Inc. ("Culligan")
   consummated a merger and acquisition in a tax-free reorganization.  The
   Company issued approximately 48.6 million shares of the Company's common
   stock for all of the outstanding common stock of Culligan (1.875 shares of
   the Company's common stock for each outstanding share and each outstanding
   option or other right to acquire a share of Culligan common stock, par value
   $.01).  In addition, the Company assumed approximately $491.7 million of
   third party institutional debt.

   Culligan is a leading manufacturer and distributor of water purification and
   treatment products and services for household, consumer and commercial
   applications.  Products and services offered by Culligan range from those
   designed to solve residential water problems, such as filters for tap water
   and household softeners, to equipment and services, such as ultrafiltration
   and microfiltration products.  Culligan also offers desalination systems and
   portable deionization services ("PDS"), designed for commercial and
   industrial applications.  In addition, Culligan sells and licenses its
   dealers to sell under the Culligan trademark five-gallon bottled water.

   This transaction has been accounted for as a pooling of interests and
   accordingly, the consolidated financial statements and notes thereto for all
   periods presented have been restated to include the accounts of Culligan.  In
   restating the Company's historical financial statements for the pooling of
   interests with Culligan, the Company's balance sheets as of March 31, 1997
   and 1998 were combined with Culligan's audited balance sheets as of January
   31, 1997 and 1998, respectively.  The results of the Company for the fiscal
   years ended March 31, 1996, 1997 and 1998 were combined with the historical
   results of Culligan for their fiscal years ended January 31, 1996, 1997 and
   1998, respectively.  Concurrent with its merger with the Company, Culligan's
   year end was recast to March 31.  Accordingly, results of Culligan for the
   two month period ended March 31, 1998 are not included in the restated
   results for the fiscal year ended March 31, 1998.  Merger expenses incurred
   to consummate the Culligan transaction totaled $49.2 million consisting of
   investment banking, printing, stock transfer, legal, accounting and
   governmental filing fees as well as certain other transaction costs, and were
   expensed during the quarter ended June 30, 1998 in which the transaction was
   completed.

   Fiscal 1998 Acquisitions Accounted for as Purchases
   ---------------------------------------------------

     On December 9, 1997, the Company, through a wholly-owned subsidiary,
   completed its tender offer ("Offer") to purchase all of the outstanding
   ordinary shares of Memtec, Ltd. ("Memtec"). The total cash purchase price was
   $397.2 million (including transaction costs of $10.6 million). Memtec is
   incorporated under the law of the State of New South Wales, Australia and has
   worldwide operations. Memtec is a leader in the designing, engineering,
   manufacturing and marketing of an extensive range of filtration products and
   systems, focusing on two principal areas of the filtration market: industrial
   filtration and water filtration. Memtec had revenues of approximately $243.6
   million and net income of approximately $7.5 million for the year ended June
   30, 1997. The purchase price was allocated to the assets and liabilities of
   Memtec based on their estimated respective fair values. The value of
   developed technology was approximately $57.2 million, and is being amortized
   on a straight-line basis over 25 years. The value of other intangible assets
   including patents, trademarks, license and distribution fees was
   approximately $7.3 million, and is being amortized over periods ranging from
   5 to 12 years.

     The Company also acquired from Memtec certain in-process research and
   development projects that had not reached technological feasibility and that
   had no alternative future uses. Such projects were valued by an independent
   appraiser using a risk adjusted cash flow model under which expected future
   cash flows were discounted using rates ranging from 31.9% to 45.9%. The
   discount rates were determined by various internal and external factors
   including general economic and industry economic conditions, cost and
   availability of capital, product completion and technology risk, competition
   and market acceptance. The future cash flows were based on significant
   estimates of revenues, cost of goods sold, operating expenses, research and
   development expenses, capital expenditures, depreciation and interest charges
   on financed capital expenditures over the next ten years. The estimates of
   these items included significant assumptions regarding (i) revenue growth,
   which was assumed to grow from no revenue in the current period for the
   projects currently in-process to substantially all of the revenue for the
   Memtec subsidiary over the ten year period as the projects in-process
   supplant or supersede the current Memtec product offerings; (ii) gross
   margin, which is projected to improve approximately 5% by the end of the ten
   year period as the new projects with higher gross margins supplant or
   supersede the current Memtec product

   offerings; (iii) operating expenses as a percentage of sales, which were
   projected to be 20%. The estimated market value of such in-process research
   and development projects was $299.5 million and was expensed at the
   acquisition date. The allocation of the purchase price of Memtec is final and
   is not expected to change materially subsequent to March 31, 1998.

     Prior to being acquired by the Company, Culligan completed the acquisition
   of the Water Filtration Business of Ametek, Inc. (the "Water Filtration
   Business") on August 1, 1997.  The purchase price was approximately $157
   million, consisting of 3,466,667 shares of Culligan's common stock and cash
   in lieu of fractional shares.  The Water Filtration Business, located in
   Sheboygan, Wisconsin, manufactures and markets point of use water filtration
   and treatment products and is a leading supplier in the do-it-yourself,
   plumbing wholesale, commercial and industrial water treatment markets.  The
   Water Filtration Business had revenues of $68.7 million and net income of
   $8.2 million for the year ended December 31, 1996.

     The purchase price was allocated to the assets and liabilities of the Water
   Filtration Business based on their estimated respective fair values.  The
   excess of fair value of net assets acquired of $51.2 million and the value of
   developed technology of $37.4 million are being amortized on a straight-line
   basis over 40 years.  In connection with this transaction, Culligan also
   acquired certain in-process research and development projects that had not
   reached technological feasibility and that had no alternative future use.
   The estimated market value of such in-process research and development
   projects was $36.3 million and was expensed during fiscal 1998.

     Prior to being acquired by the Company, Culligan also completed the
   acquisition of Protean plc ("Protean"), a United Kingdom corporation on
   December 2, 1997.  The total cash purchase price was approximately $174.0
   million, including transaction costs.  Protean is engaged in the design,
   manufacture and sale of water purification equipment sold primarily to
   commercial and industrial customers.  In connection with the acquisition,
   Culligan allocated a portion of the purchase price to net assets of
   discontinued operations.  When the Company (subsequent to its fiscal year
   end) acquired Culligan, the Company decided to retain the Analytical and
   Thermal Division and reallocated the purchase price of Protean accordingly.
   The reallocation of the purchase price did not have a material impact on the
   Company's restated financial position or results of operations.

     The purchase price was allocated to the assets and liabilities of Protean
   based on their respective fair values.  The excess of fair value of net
   assets acquired of $110.4 is being amortized on a straight-line basis over 40
   years.  In connection with this transaction, Culligan also acquired certain
   in-process research and development projects that had not reached
   technological feasibility and that had no alternative future uses.  The
   initial estimated market value of such in-process research and development
   projects was $19.5 million as of March 31, 1998 and was expensed during
   fiscal 1998.  (Subsequent to the Company's fiscal year end, the final
   estimated market value of such in-process research and development projects
   was $23.1 million as determined by an independent appraiser.  The difference
   between the initial and final estimated market values of such in-process
   research and development of $3.6 million was expensed subsequent to March 31,
   1998 during the quarter ended June 30, 1998.)

     The Company's acquisition of Memtec as well as Culligan's acquisitions of
   the Water Filtration Business and Protean have been accounted for as
   purchases and, accordingly, the results of operation for Memtec, the Water
   Filtration Business and Protean are included in the consolidated financial
   statements of the Company from the date of their respective acquisitions.
   Summarized below are the unaudited pro forma results of operations of the
   Company as though Memtec, the Water Filtration Business and Protean had been
   acquired as of April 1, 1997:

     During the year ended March 31, 1998, the Company completed other
   acquisitions with an aggregate purchase price, including acquisition costs,
   of approximately $861.0 million, consisting of $80.0 million in cash and the
   delivery of approximately 26,515,000 shares of Company common stock.  The
   excess of fair value of net assets acquired was approximately $263.8 million,
   and is being amortized on a straight-line basis over 40 years.

   Fiscal 1997 Acquisitions Accounted for as Purchases
   ---------------------------------------------------

     On October 25, 1996, the Company acquired all of the outstanding capital
   stock of the Utility Supply Group, Inc. ("USG") pursuant to an Agreement and
   Plan of Merger.  The purchase price for the acquisition of USG, including
   acquisition costs, was approximately $40 million, consisting of the repayment
   of $18.3 million of USG long-term debt paid in cash and the delivery of
   771,157 shares of Company common stock.

     USG, headquartered in Waco, Texas, is a distributor of water and wastewater
   related products and services to industrial and municipal customers
   throughout the United States.

     The acquisition of USG has been accounted for as a purchase and,
   accordingly, the results of operations of USG are included in the Company's
   consolidated statements of operations from the date of acquisition. The

(10) RESTRUCTURING CHARGES

     Concurrent with the merger with and into Kinetics and the acquisition of
   Memtec, the Company designed and implemented a restructuring plan to
   streamline its manufacturing and production base, improve efficiency and
   enhance its competitiveness. The restructuring plan resulted in a pre-tax
   charge of $141.1 million. The plan identifies certain products and
   technologies acquired in conjunction with the Memtec transaction that
   supersede products and technologies acquired in earlier acquisitions of
   membrane related businesses. As a result certain, carrying amounts of
   goodwill and other intangible assets were determined to be impaired by
   approximately $55.0 million in accordance with SFAS No. 121, which requires
   that long-lived assets be reviewed for impairment whenever events or changes
   in circumstances indicate that the carrying amount of the assets may not be
   recoverable. In determining the amount of the impairment of these assets, the
   Company valued the assets using the present value of estimated expected
   future cash flows using discount rates commensurate with the risks involved.
   The restructuring plan also included closing or reconfiguring of certain
   facilities and reducing the work force by approximately 350 employees, most
   of whom work in the facilities to be closed.

     Included in merger, restructuring, acquisition and other related charges
   are the following:

     Approximately $15.4 million of merger and restructuring related charges are
   included in accrued liabilities at March 31, 1998. Additional costs to
   complete the restructuring plan are not expected to be material.

     As a result of Culligan's acquisition of the Water Filtration Business on
   August 1, 1997 and the subsequent decision made by Culligan to exit the
   market for the sale of consumer products in the department store and mass
   merchant channels, Culligan recorded a merger and restructuring charge of
   $9.5 million during fiscal 1998.  The merger and restructuring charge
   reflects the costs of integrating and streamlining manufacturing, sales,
   distribution, research and development and administrative functions in
   Culligan's point of use business.  Included in the $9.5 million merger and
   restructuring charge are $0.7 million for severance costs related to the
   elimination of redundant employees, $1.3 million related to the write down of
   receivables, $2.5 million related to the write-down of excess property,
   equipment and other assets, $0.7 million representing legal and other
   professional fees and $4.3 million for the write down of excess inventory.

     After an income tax benefit of $38.2 million, total non-recurring charges
   during the year of $505.9 million (including purchased in-process research
   and development charges totaling $355.3 and merger, restructuring,
   acquisition and other related charges totaling $150.6) reduced earnings in
   fiscal 1998 by $467.7 million.

</TABLE>

     The Company believes that it is more likely than not that the net deferred
   tax assets, including Federal net operating loss carryforwards, will be
   realized prior to their expiration.  This belief is based on recent and
   anticipated future earnings and, in part, on the fact that the Company has
   completed several acquisitions during and including the three years ended
   March 31, 1998 of companies with strong earnings potential. A valuation
   allowance of $47.4 million at March 31, 1998 has been provided primarily for
   state and foreign net operating losses which may not be realized prior to
   expiration.

(16) SHAREHOLDERS' EQUITY

     CONVERTIBLE PREFERRED STOCK

     In January 1992 and September 1994, the Company issued 880,000 shares of a
   new Series A Cumulative Convertible Preferred Stock and 185,185 shares of a
   new Series B Convertible Preferred Stock, respectively, in connection with
   acquisitions.  On September 18, 1995, the Company repurchased and canceled
   139,518 shares of Series B Preferred stock for $4.7 million and converted
   45,667 shares of Series B Preferred Stock into 102,750 shares of Company
   common stock.  On March 4, 1996, the holder of the Company's Series A
   Preferred Stock tendered the 880,000 preferred shares for conversion into
   1,980,000 shares of Company Common Stock pursuant to terms of the security.

     COMMON STOCK

     On July 15, 1996, the Company paid in the form of  stock dividends a three-
   for-two split of the Company's common stock.  All references herein to income
   (loss) per common share and other common stock information in the
   accompanying consolidated financial statements and notes thereto have been
   restated to reflect the split.

     On December 11, 1996, the Company sold 11,804,206 shares of its common
   stock at $31.625 per share.  The net proceeds to the Company, after
   underwriting discounts and commissions and other related expenses, were
   $356.2 million.

            Notes to Consolidated Financial Statements (Continued)
 
     On May 3, 1995, the Company sold 10,350,000 shares of its common stock at
   $10.00 per share.  The net proceeds to the Company, after underwriting
   discounts and commissions and other related expenses, were $97.4 million.

   OPTIONS

     Under the Company's 1991 Employee Stock Option Plan (the "Plan"), the
   exercise price of options granted is equal to their fair market value at the
   date of grant and the maximum term of the option may not exceed 10 years.  If
   the optionee is a holder of more than 10% of the outstanding common stock of
   the Company, the option price per share is increased to at least 110% of fair
   market value, and the option term is limited to 5 years.  The total number of
   shares of common stock available under the Plan is approximately 8.9 million
   shares.  Each option granted becomes exercisable on a cumulative basis, 25%
   six months following the date of grant and 25% on each subsequent anniversary
   of the grant date until fully vested.

     Under the Company's 1991 Director Stock Option Plan (the "Directors Plan"),
   the exercise price of options granted was equal to the higher of $2.00 below
   the market price or 60% of the market price on the date of grant.  Effective
   April 1, 1996 the Directors Plan was amended to grant options equal to their
   fair market value at the date of grant.  Under the Directors Plan, each
   director of the Company who is not a full-time employee of the Company will
   receive each year an option to purchase 12,000 shares of common stock.  The
   total number of shares available under the Directors Plan is 562,500 shares.
   Compensation expense of $0.1 million was recorded in fiscal 1996 related to
   the Directors Plan.

     The per share weighted-average fair value of stock options granted during
   fiscal 1996, 1997 and 1998 was $3.40, $8.61 and $13.73 respectively, on the
   date of grant using the Black-Scholes option-pricing model with the following
   weighted-average assumptions for 1996, 1997 and 1998:

     The Company continues to apply APB Opinion No. 25 in accounting for its
   Plans and, accordingly, no compensation cost has been recognized for its
   stock options in the consolidated financial statements.  Had the Company
   determined compensation cost based on the fair value at the grant date for
   its stock options under SFAS No. 123, the Company's net income (loss) and net
   income (loss) per common share would have been reduced to the pro forma
   amounts indicated below:

            Notes to Consolidated Financial Statements (Continued)
 
     Pro forma net income (loss) and net income (loss) per common share reflects
   only options granted after April 1, 1995.  Therefore, the full impact of
   calculating compensation cost for stock options under SFAS No. 123 is not
   reflected in the pro forma net income (loss) and net income (loss) per common
   share amounts presented above because compensation reflected over the
   options' vesting period of 10 years and compensation cost for options granted
   prior to April 1, 1995 is not considered.  The Black-Scholes option valuation
   model was developed for use in estimating the fair value of traded options
   that do not have vesting restrictions and are fully transferable.  In
   addition, option valuation models require the input of highly subjective
   assumptions including the expected stock price volatility.  Because the
   Company's stock options have characteristics significantly different from
   those of traded options and because changes in the subjective input
   assumptions can materially affect the value of an estimate, in management's
   opinion, the existing models do not necessarily provide a reliable single
   measure of the fair value of stock options.
 
     Transactions involving the Plan and Directors Plan are summarized as

(17) RETIREMENT PLANS

     Pursuant to the terms of a collective bargaining agreement, one of the
   Company's U.S. subsidiaries has a defined benefit pension plan covering
   substantially all of its hourly employees. Pension plan benefits are
   generally based upon years of service and compensation. The Company's funding
   policy is to contribute at least the minimum amounts required by the U.S.
   Employee Retirement Income Security Act of 1974 ("ERISA") or additional
   amounts to assure that plan assets will be adequate to provide retirement
   benefits. Plan assets are invested in broadly diversified portfolios of
   government obligations, mutual funds and fixed income and equity securities.
   The accumulated benefit obligation under this plan is not material to the
   consolidated financial statements.

     A subsidiary of the Company provides pension and health and welfare
   benefits to employees who are members of the United Association of Journeymen
   and Apprentices of the Plumbing and Pipefitting Industry of the United States
   and Canada (the "Pipefitters Union") under multiemployer defined benefit
   plans. Contributions to the Pipefitters Union pension and health and welfare
   plans were not material to the Company's financial position as of March 31,
   1997 and 1998 nor to its results of operations for each of the years in the
   three year period ended March 31, 1998.

     In connection with the acquisition of Culligan, the Company assumed
   obligations under certain existing Culligan pension plans. Culligan has
   pension plans which cover substantially all domestic salaried employees and
   certain hourly-paid employees. Plans covering salaried employees generally
   provide pension benefits to employees who complete five or more years of
   service. Pension benefits are generally based upon years of service and
   compensation during the final years of employment. Plans covering hourly-paid
   employees generally provide pension benefits or fixed amounts for each year
   of service.

     Culligan also has an unfunded supplemental retirement plan for certain
   employees and unfunded supplemental benefit agreements for two former
   executives. The annual costs of the supplemental retirement plan and
   supplemental benefit agreements are included in the determination of net
   periodic pension cost shown below.

     Net periodic pension cost includes the following components:

</TABLE>

     Plan assets are invested primarily in equity securities and fixed income
   instruments. The Culligan pension plan does not have significant liabilities
   other than benefit obligations. The Company's funding policy is to contribute
   amounts equal to the minimum funding requirements of ERISA.

     The Company also assumed in its acquisition of Culligan a defined benefit
   health care plan that provides postretirement medical benefits to full-time
   employees who meet minimum age and service requirements. The plan is
   contributory and contains other cost-sharing features such as deductibles and
   limits on certain coverages. The Company has the right to modify or terminate
   the plan. The accumulated postretirement benefit obligation and net periodic
   postretirement benefit cost are immaterial to the Company's consolidated
   financial position and results of operations.

     The Company has a defined contribution plan (under IRC Section 401(k))
   covering substantially all U.S. salaried and hourly participating employees
   which provide for contributions based primarily upon compensation levels and
   employee contributions. The Company funds its contributions to these plans as
   provided by ERISA. Defined contribution plan expense to the Company was $4.7
   million, $7.4 million and $11.2 million for the years ended March 31, 1996,
   1997 and 1998, respectively.

     CONTINGENT LIABILITIES

     In December of 1995, allegations were made by federal and state
   environmental regulatory authorities of multiple violations in connection
   with wastewater discharges at a facility owned by the Company. The Company as
   part of its acquisition of Polymetrics on October 2, 1995 acquired the
   facility. The Company has rights of indemnity from the seller which could be
   available if monetary damages and penalties are incurred in connection with
   any alleged violations occurring prior to the Company's acquisition of
   Polymetrics. In the opinion of management, the ultimate liability that may
   result from the above matter will not have a material adverse effect on the
   Company's consolidated financial position or results of operations.

     Legal proceedings pending against the Company consist of litigation
   incidental to the Company's business and in the opinion of management, based
   in part upon the opinion of counsel, the outcome of such litigation will not
   materially affect the Company's consolidated financial position or results of
   operations.

     Remarketable or Redeemable Securities Issuance. On May 15, 1998, the
   Company issued $500 million 6.375% Remarketable or Redeemable Securities due
   2011 (Remarketing Date May 15, 2001) and $400 million 6.50% Remarketable or
   Redeemable Securities due 2013 (Remarketing Date May 15, 2003) (collectively,
   the "ROARS"). The net proceeds from the sale of the ROARS, including a
   premium payment to the Company by NationsBanc Montgomery Securities LLC, were
   $913.6 million. The net proceeds were used to repay indebtedness outstanding
   under the Senior Credit Facility, indebtedness assumed in the acquisition of
   Memtec, and a portion of the indebtedness assumed in the acquisition of
   Culligan.

     Culligan Acquisition. On June 15, 1998, a wholly owned subsidiary of the
   Company and Culligan consummated a merger and acquisition in a tax-free
   reorganization. The Company issued approximately 48.6 million shares of the
   Company's common stock for all of the outstanding common stock of Culligan
   (1.875 shares of the Company's common stock for each outstanding share and
   each outstanding option or other right to acquire a share of Culligan common
   stock, par value $.01). In addition, the Company assumed approximately $491.7
   million of third party institutional debt. The merger was accounted for as a
   pooling of interests (see note 9).
