  The Company's principal executive offices are located at 40-004 Cook Street,
Palm Desert, California 92211 and its telephone number is (760) 340-0098. In
this report, references to the Company or U.S. Filter shall mean United States
Filter Corporation and its subsidiaries, unless the context requires
otherwise.
 
  The Company has, since 1991, acquired and successfully integrated more than
75 United States based and international businesses. These acquisitions have
enabled the Company to expand significantly the segments of the water and
wastewater treatment industry in which it participates, to enter into
additional geographic areas and serve additional industries, municipalities,
governments and other customers and to expand its installed base, service
network and range of products and technologies. The Company intends to
actively seek additional acquisitions that enhance its geographic network,
customer base, and range of product offerings, technologies, markets and
industries served. The significant businesses acquired by the Company since
March 31, 1996 are described below.
 
  PED. On January 6, 1997, the Company acquired the Process Equipment Division
("PED") of United Utilities Plc for approximately $166 million in cash,
including acquisition costs, and 1,320,312 shares of Common Stock of the
Company, subject to post-closing adjustments. The acquisition of PED provides
the Company with a significant manufacturing and distribution presence in the
municipal market for wastewater treatment equipment and systems, principally

Florida, Illinois, Kansas, Louisiana, Minnesota, New Mexico, Oklahoma,
Tennessee and Texas; and a number of small bottled water businesses for the
individual consumer market.
 
THE WATER TREATMENT INDUSTRY
 
  Global population growth, economic expansion, scarcity of available water
resources, heightened public concern about water quality and growing
regulatory and legislative requirements have resulted in the continued growth
in demand for water and wastewater treatment. In addition to the need for
potable water, industrial companies require treated water for most
manufactured products, whether as an ingredient in the finished product or as
part of the manufacturing process. Accordingly, most manufacturers utilize
water treatment systems to purify their incoming, or "process", water. Public
water departments and private water companies, responsible for providing
potable water, employ water treatment technology to purify their water supply.
Furthermore, government regulations require most industrial companies and
municipalities to treat their outgoing wastewater.
 
  Customers of the water and wastewater treatment industry can be classified
into three broad categories: (i) industrial and commercial businesses, which
include companies in such markets as pharmaceuticals, microelectronics,
automotive, power generation, chemical processing, oil and metal finishing;
(ii) municipal and private suppliers of public water and wastewater services;
and (iii) individual consumers of bottled water, household point-of-use
products, such as domestic filtration systems and parts, and water softening
and conditioning equipment.
 
 INDUSTRIAL AND COMMERCIAL USERS
 
  Industrial and commercial users have a significant need for treated water
because it is a necessary component in many products and industrial and other
processes. The quality of water varies dramatically across geographic regions,
and water contains impurities that, if untreated, can render it effectively
useless for most
 
                                       3
<PAGE>
 
industrial purposes. The use of untreated water in manufacturing processes can
result not only in inconsistent product quality, but also in substantial
equipment degradation, which can lead to costly maintenance or replacement
costs. Consequently, most manufacturers treat their process water in order to
maintain a consistently acceptable degree of purity. For example, treated
water is an integral component of many consumer goods and is used in the
manufacture of pharmaceutical products, microelectronics and chemicals. Food
and beverage manufacturers require water with consistent quality to preserve
uniformity of taste and appearance in their products. As a result of these
process specifications, industrial customers often require a broad range of
treatment technologies to treat their process water.
 
  In addition to treating their process water to ensure product quality,
industrial users are often required to treat their wastewater. Government
regulations regarding the disposal of aqueous industrial waste, combined with
public concern regarding industrial pollution, have led to increased awareness
on the part of businesses and public utilities as to the benefits of
wastewater treatment and waste minimization. In response to higher water
prices and rising wastewater discharge fees, industrial manufacturers have
also become aware of the cost-effectiveness of recycling their wastewater. As
a result of these factors, industrial companies increasingly require complex
systems and equipment to treat and recycle process water and wastewater.
 
 MUNICIPAL USERS
 
  Public awareness and governmental concern regarding the increasing scarcity
of water, the quality of drinking water, and the potential health hazards
associated with waste products discharged into the environment, have resulted
in legislation, regulation and enforcement requiring strict standards for
potable water and restrictions on the discharge of pollutants in municipal
wastewater.
 
  The Company believes that, in many areas of the United States, aged
municipal water and wastewater treatment infrastructure is operating at or
near capacity, is in need of substantial capital expenditures and is not well-
equipped to satisfy increasing regulatory and legislative requirements. In
addition, many municipalities are experiencing reduced economic resources. The
Company believes that, as a result, many such customers are seeking innovative
solutions to their water treatment needs, such as improved technologies and
equipment, and various outsourcing and service options, such as contract
operations and privatization. Privatization involves the transfer of ownership
and operation of water and wastewater treatment facilities to companies
capable of providing such services on a long-term basis. Outside the United
States, aged infrastructure and, in many areas, underdeveloped infrastructure,
also require significant capital outlays and advanced technological approaches
to address the populations' potable water and sewage treatment needs.
 
 INDIVIDUAL CONSUMERS
 
  The market for individual consumers consists of bottled water, point-of-use
products, such as residential filtration systems and parts, and water
softening and conditioning equipment installed at the point of entry to a
household water system. Consumers' needs vary by geographic location as a
result of differing water qualities and level of economic development. This
segment of the industry is highly fragmented, and the Company believes there
are thousands of participants in the potable water and point-of-use products
markets.
 
PRODUCTS AND SERVICES
 
 PROCESS WATER GROUP
 
  The Company's Process Water Group provides single-source solutions for the
treatment of industrial process water and municipal drinking water through
what the Company believes to be the industry's broadest range of treatment
systems, services and proven technologies.

filtration), ion exchange, continuous deionization ("CDI"), electrodialysis,
carbon adsorption, biological processes, oxidation, disinfection, aeration,
coagulation, flocculation, evaporation and crystallization. The Company's
proprietary CDI process uses ion exchange resins, ion exchange membranes and
an electrical current to produce high-purity water continuously, without the
need for strong chemicals such as sulfuric acid and caustic soda required in
typical ion exchange regeneration systems. The Company's Membralox(R) ceramic
membranes used in filtration permit the achievement of selective separations
in extreme operating environments.
 
  The water treatment equipment and systems sold by the Process Water Group
are designed, engineered and assembled by the Company from one or more pieces

facility. These facilities receive and treat wastes generated primarily by the
metal finishing industry and printed circuit board manufacturers, and recover
from these wastes and sell reusable chemicals and metals. These facilities
offer the Company's customers a cost-effective recovery approach that reduces
processing costs, the quantity of sludge generated and the environmental
exposure associated with industrial waste. The Company also operates a
facility in Parker, Arizona, which is authorized under Section 3005 of RCRA
for the reactivation of spent carbon. The Company is currently negotiating the
final terms and conditions for a RCRA Part B permit for such facility.
 
 Customer Markets
 
  Municipalities in North America, Europe, Asia and Latin America are a
significant market for systems and products manufactured by the Wastewater
Group in the United States. Municipal sewage plants often utilize three stages
of treatment (primary, secondary and tertiary) before discharge to the
environment. The Company offers wastewater and biosolids treatment systems to
address those requirements. In addition, the Company's media filtration,
reverse osmosis and ion exchange technologies have the capability of adding a
fourth stage of treatment of municipal wastewater by removing remaining
contaminants to a purity level that allows water to be recycled and reused in
industrial applications. These technologies can reduce the impact of
industrial growth in communities where water tables are low.
 
  Systems produced by the Wastewater Group are marketed to a variety of
industrial customers. Markets include the pulp and paper, chemical,
petrochemical, mining, power generation, meat and poultry, food processing,
automotive, metal finishing and microelectronics industries. The recycle/reuse
systems offered by the Company permit zero liquid discharge applications,

 CONSUMER PRODUCTS GROUP
 
  The Company sells, installs and services a wide range of products which
address household water problems. These products include water softening and
conditioning equipment and other products installed at the point of entry to a
residential water system, designed to soften hard water by reducing or
removing minerals through ion exchange technology. The Consumer Products Group
also sells point-of-use filtration units for improving the quality of drinking
water, which utilize media filtration, reverse osmosis and/or carbon filter
processes. These products are designed to be installed under sinks or directly
at the point of use. Point-of-use systems are designed to reduce or remove
from household water dirt and other sediment, rust, lead, chlorine, sulfur,
off-tastes, odors, and other chemicals and microscopic impurities, including
parasitic protozoan cysts.
 
  Through the Consumer Products Group's 25 service branches located
principally in the Midwestern United States, Company representatives provide
solutions to household water problems through testing and analysis, product
selection, installation, monitoring and service. The Company also offers
rental and financing of systems to residential customers.
 
  Point-of-entry systems are manufactured at the Company's facilities in
Rockford, Illinois, as well as purchased from third party vendors. Point-of-
use products sold and installed by the Consumer Products Group are purchased
from third parties. Testing and analysis of household water samples is
performed at Process Water Group laboratories in Rockford, Illinois.
 
  The Company also sells water in five-gallon bottles on a route basis through
its residential service branches, and in a limited number of shopping centers
on a walk-up basis. Purified drinking water is produced and bottled in five-
gallon bottles by the Company at four bottling locations in the United States.
The Consumer Products Group's representatives typically pick up for refill and
deliver the five-gallon bottles to a customer's home or office on a regular
route. Customers rent the bottled water dispensers from the Company. In
addition, at a small number of locations in Texas and Florida, the Company
also sells purified water by refilling customer-supplied containers at
shopping center locations. Consumer water filtration and water-quality related
products are also sold at these locations. The Company currently does not
participate in any other segment of the bottled water market.

<PAGE>
 
presence allows the Company to provide systems that respond to important local
differences in environmental legislation, water quality, availability and
cost. A wide range of separation processes and treatment technologies are
employed in these systems, including most of those utilized by the Process
Water Group and the Wastewater Group in the United States. The Company's
systems and products are sold internationally to municipalities for drinking
water purification, sewage treatment and sludge handling. The Company also has

SALES AND MARKETING
 
  The Company maintains a worldwide distribution network of sales and service
facilities, a global network of manufacturers' representatives and
international representatives, and numerous distributors and licensees.
 
  In the United States, sales and marketing responsibilities for the Process
Water Group, Wastewater Group and Consumer Products Group are divided across
five geographic regions in the U.S. Each industrial, commercial and municipal
sales prospect is reviewed to determine which of the Company's engineering and
manufacturing resources should be utilized to best meet the customer's needs.
Technical support is available across the Company to assist marketing
personnel in working with the end-user to select the appropriate technology
for a given application.
 
  Process Water Group products and systems are sold predominantly through a
direct sales force. The Wastewater Group's sales are made principally through
a network of independent manufacturer's representatives.
 
  The Company's manufacturer's representatives are independent businesses
which are paid on a commission basis and in certain cases have the exclusive
right to sell the Company's products and systems in a specified geographical
area. The Company provides both engineering and marketing support to its
manufacturer's representatives.
 
  A portion of the Company's revenues are derived from recommendations by
independent engineers and consultants who advise the ultimate customer. Both
the Company's manufacturers' representatives and direct sales force work with
engineers, consultants and customers to encourage them to specify the
Company's products.
 
  Sales of process water, wastewater and sewage treatment systems and products
outside the United States are conducted through a direct sales force and
international representatives. In addition, a number of licensees manufacture
and sell certain of the Company's products in Europe, Asia, Africa, Australia
and Mexico. The Company provides technical support to these licensees and is
either paid a royalty on sales or participates in the sale directly. For the
fiscal years ended March 31, 1995, 1996 and 1997, the Company's sales outside
the United States were approximately $112.8 million, $212.9 million and $419.5
million, respectively, and accounted for approximately 19%, 26% and 30%,
respectively, of the Company's total sales.
 
  The Distribution Group's equipment and supplies are marketed by Company-
employed salesmen. Salesmen call directly on customers within their assigned
territories and work with architects, engineers and government agencies to
assist customers in determining their product needs.
 
RAW MATERIALS AND SUPPLIES
 
  Raw materials, primarily steel, filtration media, ion exchange resins,
membranes and component parts such as pumps and valves, and products purchased
for resale by the Distribution Group, are available from a number of sources.
The Company has not experienced difficulty in obtaining the materials,
components and supplies used in its operations.

BACKLOG AND SEASONALITY
 
  The Company had the following backlog as of March 31, 1996 and 1997, which
includes capital equipment purchase orders and revenues expected to be
generated during the next 12 months under certain long-term contracts. The
capital equipment orders are scheduled for delivery and installation during
the following 12 months and are believed by management to be firm.
 
<TABLE>
<CAPTION>
                DATE                           AMOUNT
                ----                       --------------
                                           (IN THOUSANDS)
            <S>                            <C>
            March 31, 1996................    $219,124
            March 31, 1997................    $644,535
</TABLE>
 
  The rate of booking new orders varies from month to month. In addition, the
orders have varying delivery schedules, and the Company's backlog as of any
particular date may not be representative of actual revenues for any
succeeding period. There is no material backlog for water distribution
equipment and supplies since these orders normally are shipped within one to
ten days following receipt of an order. Backlog also is not a meaningful
measure of ongoing business in the residential water business.
 
  Certain of the Company's contracts for engineered products and services
provide for progress payments during the engineering and manufacturing period.
The balance is due upon acceptance or start-up, or, in the case of most
municipal and governmental purchasers, 90 to 180 days after delivery and
installation. Demand for most of the Company's products and services is not
typically affected by seasonal changes. The Distribution Group's operations
are affected by winter weather in parts of the United States, and generally
can be expected to generate lower sales in the third and fourth fiscal
quarters.
 
PRODUCT DEVELOPMENT; PATENTS, TRADEMARKS AND LICENSES
 
  In order to provide its customers with cost-effective water treatment
solutions, the Company offers a wide variety of filtration and purification
technologies. The Company uses its own research and development, augmented by
customer-funded, vendor-funded and government-funded research spending, in
order to provide its customers with advanced products. In addition, the
Company uses its analytical laboratories to perform water analyses and to test
the effectiveness of filtration media and techniques in order to enhance the
Company's capability to design systems tailored specifically for the
particular needs of customers. The Company's product development expenditures
for the fiscal years ended March 31, 1995, 1996 and 1997 were approximately
$5.5 million, $6.5 million and $8.3 million, respectively.
 
  The Company currently owns a significant number of patents in the United
States and in various countries worldwide. Although the Company believes that
the patents and trademarks associated with the Company's various product lines
are of value, it does not consider any of them to be essential to its
business.
 
COMPETITION
 
  The water and wastewater treatment industry is fragmented, with numerous
regional participants in the United States and in countries throughout the
world who are limited in their geographic scope. This fragmentation is
primarily due to local differences in water quality and supply, different
levels of demand for water resulting from varying concentrations of industry
and population, and local governmental regulation. Most participants in the
water and wastewater treatment industry provide a limited number of treatment
technologies, a limited number of products or services, or focus on a
particular industry. While the number of industry participants ranges from
several large companies to hundreds of small local companies, there are few
competitors in the industry that offer a full range of water and wastewater
treatment equipment, technologies and services. The Company believes it offers
the industry's broadest range of cost-effective treatment systems, services
and proven technologies.
 
 
                                      12
<PAGE>
 
  The water and wastewater treatment markets are highly competitive. The
Company knows of no reliable statistics that provide a basis from which to
estimate the Company's relative competitive position in these markets. The
principal methods of competition in the water and wastewater treatment markets
in which the Company competes are technology, service, price, product
specifications, customized design, product knowledge and reputation, ability
to obtain sufficient performance bonds, timely delivery, the relative ease of
operation and maintenance and the prompt availability of replacement parts. In
the municipal contract bid process, pricing and the ability to meet bid
specifications are the primary considerations. For privatization and
outsourcing projects, performance guarantees are also a factor. While no
competitor is considered dominant, there are competitors that are divisions or
subsidiaries of larger companies which have significantly greater resources
than the Company.
 
  In connection with the marketing of water distribution equipment and
supplies, the Company competes with a large number of independent wholesalers,
other distribution chains similar to the Company and manufacturers who sell
directly to customers. The principal methods of competition include product
knowledge by the sales force, prompt delivery following receipt of an order,
local service and price. Due to the various sources and methods of competition
and types of products sold by the Company, the Company knows of no reliable
statistics upon which there might be based an estimate of the Company's
relative competitive position in this market. However, the Company believes
that it is one of the largest distributors of water distribution equipment and
supplies in the United States based on annual revenues from sales of such
products.
 
  The residential water market is also highly competitive and fragmented. The
Company competes in this market with companies with national distribution
networks, businesses with regional scope and local product assemblers or
service companies, as well as retail outlets. The principal methods of
competition in this market are distribution capabilities, product
specifications, product knowledge, reputation, technology, service and price.
The Company believes that there are thousands of participants in the household
water market.
 
PRODUCT WARRANTIES; INSURANCE
 
  The Company generally offers one-year product warranties on its equipment.
In some instances the warranties may be for shorter or longer periods,
consistent with market practices. Performance guarantees apply to most of the
Company's systems. The costs incurred by the Company to date under its product
warranties and systems guarantees have not been material.
 
  The Company maintains insurance for itself and its principal United States
based and international subsidiaries in amounts and with coverages which the
Company believes to be adequate and appropriate for the covered risks.
 
EMPLOYEES
 
  As of March 31, 1997, the Company had approximately 10,000 full-time
employees assigned to the Company's various worldwide offices and facilities.
Certain of the Company's United States employees at Rockford, Illinois;
Whittier, California; Washington, Illinois; Granite City, Illinois; and
Warren, Michigan are covered by collective bargaining agreements, the terms of
which expire, respectively, on April 1, 1999, April 30, 1998, April 14, 1998,
November 30, 1997 and July 30, 1999. Certain of the Company's non-United
States based employees also are covered by collective bargaining agreements.
The Company believes that its relationships with the unions and with its non-
represented employees are good.

ITEM 2--PROPERTIES
 
  The Company has a global network of approximately 470 sales and service
facilities and 63 manufacturing plants. Because the Company has grown by
acquisition, the Company's facilities vary in terms of age and condition, but
management generally believes that these facilities are suitable and adequate
for their respective operations. Many of the Company's manufacturing
facilities operated at or near their productive capacities during fiscal 1997.
 
  The Company's corporate headquarters is located in a Company-owned office
building in Palm Desert, California, with 18,000 square feet of floor space. A
description of the Company's other principal facilities is included in Item 1
of this Form 10-K. Approximately 20% of the Company's manufacturing facilities
are owned, with the remainder under leases expiring from June 30, 1997 through
April 30, 2026, in most cases with Company options to renew. Of the Company's
37 regeneration plants, 11 are owned and the majority of the remainder are
held under short-term leases. In most cases, the Company's 63 manufacturing
and 37 regeneration plants include sales and service offices. The Company also
owns or leases various small production facilities not described in this Form
10-K. A small number of the Company's facilities are subject to mortgages
securing notes payable due in fiscal years 1999 and 2010. See Note 11 of Notes
to Consolidated Financial Statements included in Item 8 of this Form 10-K.
 
ITEM 3--LEGAL PROCEEDINGS
 
  Various lawsuits, claims and proceedings have been or may be instituted or
asserted against the Company, including those pertaining to environmental,
product liability and safety and health matters. While the amounts claimed may
be substantial, the ultimate liability cannot now be determined because of the
considerable uncertainties that exist. Therefore, it is possible that results
of operations or liquidity in a particular period could be materially affected
by certain contingencies. However, based on facts currently available,
management believes that the disposition of matters that are pending or
asserted will not have a materially adverse effect on the financial position
of the Company. Information regarding certain environmental contingencies is

DIVIDENDS
 
  The Company currently intends to retain earnings to provide funds for the
operation and expansion of its business and accordingly does not anticipate
paying cash dividends on the Common Stock in the foreseeable future. Any
payment of cash dividends on the Common Stock in the future will depend upon
the Company's financial condition, earnings, capital requirements and such
other factors as the Board of Directors deems relevant. Under the Company's
credit agreement with lenders for whom The First National Bank of Boston is
acting as Managing Agent, no dividends may be paid on the Common Stock without
the consent of lenders whose lending commitments constitute a majority of the
lending commitments thereunder.

(1) The historical consolidated financial data for the fiscal years ended
    March 31, 1993 through March 31, 1996 have been restated to include the
    accounts and operations of Zimpro, Davis and Sidener, which were merged

    and accounted for as poolings of interests.

    Societe des Ceramiques Techniques, S.A. ("SCT"), acquired April 1, 1992
    and three months of The Permutit Company, Inc., a United States company

    ended March 31, 1993 also includes extraordinary gains of $.4 million
    resulting from the forgiveness of debt in connection with the buyout of a
    capital lease obligation and $.5 million resulting from the Company's
    Davis subsidiary's adoption of SFAS No, 109, "Accounting for Income
    Taxes."
(3) The fiscal year ended March 31, 1994 includes four months of results of
    Ionpure Technologies Corporation and IP Holding Company ("Ionpure"),
    acquired December 1, 1993 and accounted for as a purchase. Selling,
    general and administrative expenses for the year ended March 31, 1994

    the dates of their respective acquisitions, accounted for as purchases.
    See Note 9 of Notes to Consolidated Financial Statements. Selling, general
    and administrative expenses for the year ended March 31, 1996 includes
    charges totaling $3.2 million related to the write-down of certain patents
    and equipment of Zimpro.
(6) Net income (loss) per common share amounts are after (i) dividends on the

    million for the fiscal year ended March 1995 and $.5 million for the

    was converted into shares of Common Stock in March 1996.
(7) The fiscal year ended March 31, 1997 includes the results of operations of

    includes merger expenses of $5.6 million, related to the acquisition of
    Davis, which was accounted for as a pooling of interests.
 
ITEM 7--MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS
 
  The discussion contained in this Item 7 should be read in conjunction with
the Company's Consolidated Financial Statements and Notes thereto included
elsewhere in this Form 10-K.
 
GENERAL
 
  The Company's strategy is to offer a single-source solution to industrial
and municipal customers through what the Company believes is the industry's
broadest range of cost-effective systems, products, services and proven
technologies. Accordingly, since July 1991, the Company has acquired and
integrated more than 75 businesses with substantial expertise in the design
and manufacture of systems of 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 May 1996, August 1996 and March 1997 subsidiaries of the Company merged
with Zimpro, Davis, and Sidener, respectively, in transactions accounted for
as poolings of interests. Historical consolidated financial data for the
fiscal years ended March 31, 1993 through March 31, 1996 have been restated to
reflect these acquisitions.

 Revenues
 
  Revenues for fiscal 1997 were $1,376.6 million, an increase of $564.3
million from $812.3 for the comparable period of the prior fiscal year. This
69.5% increase was due primarily to acquisitions completed by the Company
after fiscal 1996. For fiscal 1997 revenues from capital equipment sales
represented 40.0% of total revenues, while revenues from services and
operations represented 14.0% of total revenues, revenues from distribution
represented 31.0% of total revenues and revenues from replacement parts and
consumables represented 15.0% of total revenues.
 
 Gross Profit
 
  Gross profit increased 70.0% to $350.4 million for fiscal 1997 from $206.1
million for the comparable period of the prior fiscal year. Total gross profit
as a percentage of revenue ("gross margin") was 25.5% for fiscal 1997 compared
to 25.4% for the comparable period of the prior fiscal year.
 
 Selling, General and Administrative Expenses
 
  For fiscal 1997, selling, general, and administrative expenses, excluding
merger expenses, increased $101.2 million to $261.9 million as compared to the
$160.7 million in the comparable period in the prior year. During this period,
selling, general and administrative expenses, excluding Davis merger expenses,
were 19.0% of revenues compared to 19.8% for the comparable period in the
prior year. This decrease was primarily due to certain economies of scale
accompanying the Company's recent acquisitions.
 
  Excluding Davis merger expenses, operating income as a percentage of
revenues increased to 6.4% for fiscal 1997 from 5.6% for the corresponding
period in fiscal 1996 due primarily to the decrease in the percentage of
selling, general and administrative expense to revenues.

 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 $22.6 million for fiscal 1997 from $15.2
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; and (iv) borrowings under the
Company's bank line of credit. At March 31, 1997, the Company had cash, cash
equivalents and short-term investments of $128.4 million.
 
 Income Tax Expense
 
  Income tax expense increased to $17.5 million in fiscal 1997 from $13.2
million in the corresponding period in the prior year. The Company's effective
tax rate for fiscal 1997 was 27.5% as compared to 37.5% 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 $24.2 million to $46.2 million from
$22.0 million for the same period in the prior year. Excluding Davis merger
expenses, net income totaled $50.2 million, an increase of 128.2% over the same
period in the prior year. Net income per common share for fiscal 1997 and 1996
were as follows:

TWELVE MONTHS ENDED MARCH 31, 1996 ("FISCAL 1996") COMPARED WITH TWELVE MONTHS
ENDED MARCH 31, 1995 ("FISCAL 1995")
 
 Revenues
 
  Revenues for fiscal 1996 were $812.3 million, an increase of $211.5 million
from $600.8 million for fiscal 1995. This 35.2% increase was due primarily to
acquisitions completed by the Company in fiscal 1995 and fiscal 1996. See Note
9 of Notes to Consolidated Financial Statements related to acquisitions.
 
 Gross Profit
 
  Gross profit increased 50.6% to $206.1 million for fiscal 1996 from $136.9
million for fiscal 1995. Gross margin increased to 25.4% for fiscal 1996 as
compared to 22.8% for fiscal 1995. The increase in gross margin through fiscal
1996 was due to: (i) a continued strengthening of gross margin in the recurring
and higher margin service-based revenue business; (ii) rationalization of
operations and economies of scale from the integration of acquisitions; and
(iii) a focus on products with higher gross margins in Davis' distribution
business.
 
 Selling, General and Administrative Expenses
 
  Selling, general and administrative expenses increased to $160.7 million for
fiscal 1996 from $108.8 million for fiscal 1995. This increase was primarily
due to the addition of sales and administrative personnel accompanying the
Company's acquisitions during the period. As a percentage of revenues, selling,
general and
 
                                       22
<PAGE>
 
administrative expenses were 19.8% for fiscal 1996, as compared to 18.1% for
fiscal 1995. This increase was due primarily to a write-down of certain
patents and equipment totaling $3.2 million at the Company's Zimpro subsidiary
and, to a lesser extent, increased levels of incentive compensation earned by
management and employees of Davis as compared to fiscal 1995.
 
  Notwithstanding the increase in selling, general and administrative expenses
as a percentage of revenues, operating income as a percentage of revenues
increased from 4.7% for fiscal 1995 to 5.6% for fiscal 1996 due primarily to
improvement in gross margin.
 
 Interest Expense
 
  Interest expense increased to $15.2 million for fiscal 1996 from $8.1
million for fiscal 1995. Interest expense for fiscal 1996 consisted primarily
of interest on the Company's 5% Convertible Subordinated Debentures due 2000
issued October 20, 1993 and approximately seven months of interest on the
Company's 6% Convertible Subordinated notes due 2005 issued September 18,
1995, respectively, and interest on increased borrowings under the Company's
bank line of credit, which was used to finance the Company's revenue expansion
and acquisitions during the period.
 
 Other Income (Expense)
 
  Other income (expense) increased to $5.0 million of income for fiscal 1996
from $1.3 million of income for fiscal 1995. Other income consisted primarily
of interest income on short-term investments, which increased during fiscal
1996 primarily as a result of the Company's sale of $140.0 million aggregate
principle amount of 6% Convertible Subordinated notes on September 18, 1995
and the Company's issuance of 10.4 million shares of Common Stock on May 3,
1995 with net proceeds of approximately $98.1 million.
 
 Income Tax Expense
 
  Income tax expense increased to $13.2 million for fiscal 1996 from $6.0
million for fiscal 1995. This increase was attributable to increased income.
The Company's effective tax rate for fiscal 1996 was 37.5% and for fiscal 1995
was 28.2%. This increase in effective rate in fiscal 1996 is due primarily to
a net loss before income taxes of $6.1 million incurred at Zimpro (see
"Selling, General and Administrative Expenses") for which no income tax
benefit was recognized because its realization was not assured and because of
nondeductibility of certain items. As of March 31, 1996, the Company had net
operating loss carryforwards in France of approximately $20.0 million and
other European countries of approximately $7.3 million for which no financial
statement benefit has been recognized. In addition, the Company had net
operating loss carryforwards generated from its Liquipure subsidiary of
approximately $14.4 million for which financial statement benefit was
recognized in fiscal 1996. The Company also had net operating loss
carryforwards generated from Zimpro of approximately $2.9 million for which
financial statement benefit has not been recognized. In addition, the benefit
of the French loss carryforwards was required to be shared equally between the
Company and Aluminum Corporation of America until March 31, 1997. See Note 14
of Notes to Consolidated Financial Statements related to income taxes.
 
 Net Income
 
  Net income increased to $22.0 million for fiscal 1996 from $15.3 million for
fiscal 1995. Net income per common share was $0.49 per share (based upon 43.7
million weighted average common shares outstanding) for fiscal 1996 and $0.49
per common share (based upon 29.8 million weighted average common shares
outstanding) for fiscal 1995, after deducting $.5 million and $.7 million for
dividends on the Company's preferred shares for fiscal 1996 and 1995,
respectively.

 Liquidity and Capital Resources
 
  The Company's principal sources of funds are cash, cash equivalents and
other working capital, cash flow generated from operations and borrowings
under the Company's bank line of credit. At March 31, 1997 the Company had
working capital of $471.6 million, including cash, cash equivalents and short-
term investments of $128.4 million. The Company's long-term debt at March 31,
1997 included $140.0 million aggregate principal amount of 6% Convertible
Subordinated Notes due 2005, $414.0 million aggregate principal amount of 4.5%
Convertible Subordinated Notes due 2001 and other long-term debt totaling
$23.1 million and bearing interest at rates ranging from 2.0% to 9.2%.
 
  Capital expenditures totaled $19.3 million, $30.2 million and $45.4 million
for fiscal years ended March 31, 1995, 1996, 1997, respectively. Although the
Company has no material firm commitments for capital expenditures, capital
expenditure requirements are expected to increase as a result of the Company's
anticipated growth, including from the recent acquisitions and specifically
the acquisitions of WSMG, USG, WaterPro and PED.
 
  As of March 31, 1997, the Company has an unsecured multicurrency bank line
of credit of $400.0 million, of which there were outstanding borrowings of
$6.5 million and outstanding letters of credit of $62.1 million. Borrowings
under the Credit Agreement bear interest at certain Eurocurrency rates or at
the First National Bank of Boston's base rate and have a five year maturity.
 
  The Company believes its current cash position, cash flow from operations,
and available borrowings under the Credit Agreement will be adequate to meet
its anticipated cash needs for 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 and successfully
integrated more than 75 United States based and international businesses with
strong market positions and substantial water and wastewater treatment
expertise. The Company plans to continue to pursue acquisitions that
complement its technologies, products and services, broaden its customer base
and expand its global distribution network. 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. Although the Company generally has been successful in pursuing
these 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, nationalization and possible social, political and
economic instability.
 
                                      24
<PAGE>
 
  Reliance on Key Personnel. The Company's operations 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. There
are no employment agreements between the Company and the members of its senior
management, except Thierry Reyners, the Company's Executive Vice President--
European Group, and Harry K. Hornish, Jr., the Company's Executive Vice
President--Distribution Group. Should any of the senior managers be unable to
continue in their present roles, 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, costs to complete increase,
delivery schedules 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 and Seasonality. 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 could have an 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 northern
climates. As a result of recent acquisitions, 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 an adverse effect on the
Company's revenues and profitability.
 
  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 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 federal
and state environmental regulatory authorities have commenced civil
enforcement actions related to alleged multiple violations of applicable
wastewater pretreatment standards by a wholly owned subsidiary of the Company
at a Connecticut ion exchange regeneration facility acquired by the Company in
October 1995 from Anjou International Company ("Anjou"). A grand jury
investigation is pending which is believed to relate to the same conditions
that were the subject of the civil actions. The Company has certain rights of
indemnification from Anjou which may be available with respect to these
matters. In addition, 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. In
other matters, the Company has been notified by the United States
Environmental Protection Agency that it is a potentially responsible party
under the Comprehensive Environmental Response, Compensation, and Liability
Act ("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.
The Company does not believe that its liability, if any, relating to such
matters 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 or financial position.
 
                                      25

  Competition. The water and wastewater treatment industry is fragmented and
highly competitive. The Company competes with many United States based and
international companies in its global markets. The principal methods of
competition in the markets in which the Company competes are technology,
prompt availability of local service capability, price, product
specifications, customized design, product knowledge and reputation, ability
to obtain sufficient performance bonds, timely delivery, the relative ease of
system operation and maintenance, and the prompt availability of replacement
parts. In the municipal contract bid process, pricing and ability to meet bid
specifications are the primary considerations. While no competitor is
considered dominant, there are competitors which have significantly greater
resources than the Company, which among other things, could be a competitive
disadvantage to the Company in securing certain projects.
 
  Technological and Regulatory Change. The water and wastewater treatment
business is characterized by changing technology, competitively imposed
process standards and regulatory requirements, each of which influences the
demand for the Company's 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
technology 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.
 
  Municipal and Wastewater Market. Completion of certain of the Company's
acquisitions has increased significantly the percentage of the Company's
revenues derived from municipal customers. While municipalities represent an
important market in 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 significant
resources and greater lead times than industrial projects. In addition, demand
in the municipal market 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. Zimpro is party to certain agreements (entered into in 1990 at the
time Zimpro was acquired from unrelated third parties by the entities from
which it was later acquired by the Company), pursuant to which Zimpro agreed,
among other things, to pay the original sellers a royalty of 3.0% of its
annual consolidated net sales of certain products in excess of $35.0 million
through October 25, 2000. Under certain interpretations of such agreements,
with which the Company disagrees, Zimpro could be liable for such royalties
with respect to the net sales attributable to products, systems and services
of certain defined wastewater treatment businesses acquired by Zimpro or the
Company or the Company's other subsidiaries after May 31, 1996. The defined
businesses include, among others, manufacturing machinery and equipment, and
engineering installation, operation and maintenance services related thereto,
for the treatment and disposal of waste liquids, toxic waste and sludge. One
of the prior sellers has revealed in a letter to the Company an interpretation
that may be contrary to that of the Company. The Company believes that it
would have meritorious defenses to any claim based upon any such
interpretation and would vigorously pursue the elimination of any threat to
expand what it believes to be its obligations pursuant to such agreements.
 
  Impact of Recently Issued Accounting Standards. In February 1997, the
Financial Accounting Standards Board issued a new statement titled "Earnings
Per Share." The new statement is effective for fiscal years ending after
December 15, 1997. The Company does not believe that adoption of this new
standard will have a material effect on the consolidated financial statements.

                         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, 1996 and 1997, and
the related consolidated statements of income, shareholders' equity, and cash
flows for each of the years in the three-year period ended March 31, 1997.
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 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, 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, 1996 and 1997, and
the results of their operations and their cash flows for each of the years in
the three-year period ended March 31, 1997, in conformity with generally
accepted accounting principles.

               UNITED STATES FILTER CORPORATION AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                   YEARS ENDED MARCH 31, 1995, 1996 AND 1997
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PRINCIPLES OF CONSOLIDATION
 
  The consolidated financial statements include the financial statements of
United States Filter Corporation and its wholly owned subsidiaries (the
"Company") (see note 9). 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 total
estimated cost, is applied to total estimated revenue. Provision is made for
the entire amount of future estimated losses on contracts in progress in the
period in which 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 those 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
 
  The Company follows Statement of Financial Accounting Standards ("SFAS") No.
109, "Accounting for Income Taxes." Under this method, 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 indefinately
reinvested in those operations.
 
FOREIGN CURRENCY TRANSLATION
 
  In accordance with SFAS No. 52, "Foreign Currency Translation," those assets
and liabilities that are 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 are immaterial.
 
INVENTORIES
 
  Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out method.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
PROPERTY, PLANT AND EQUIPMENT
 
  Property, plant and equipment are stated at cost. Depreciation is calculated
on the straight-line method over the estimated useful lives of the respective
assets which range from three to 25 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. Based upon its most recent analysis, the Company
believes that no material impairment exists at March 31, 1997.
 
INVESTMENTS IN UNCONSOLIDATED JOINT VENTURES
 
  Investments in unconsolidated joint ventures are accounted for using the
equity method, under which the Company's share of earnings or losses from
these joint ventures is reflected in income as earned and dividends are
credited against the investment when received.
 
UNAMORTIZED DEBT ISSUANCE COSTS
 
  Unamortized debt issuance costs, aggregating $6.2 million and $16.9 million
at March 31, 1996 and 1997, respectively, have been deferred and are being
amortized over the term of the related debt (see note 12).
 
WARRANTIES
 
  The Company's products are generally under warranty against defects in
material and workmanship for a period of one year. The Company has accrued for
estimated future warranty costs.
 
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 PER COMMON SHARE
 
  Income per common share is computed based on the weighted average number of
shares outstanding. Common stock equivalents consisting of convertible
preferred stock, convertible subordinated debentures and common stock options
are included in the computation of income per share when their effect is
dilutive.

  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, 1997 of companies with strong earnings potential. A valuation
allowance of $20.7 million at March 31, 1997 has been provided primarily for
state and foreign net operating losses which may not be realized prior to
expiration.
 
(15) 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 December 5, 1994 and 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
to income per common share and other common stock information in the
accompanying consolidated financial statements and notes thereto have been
restated to reflect these splits.

  On December 11, 1996, the Company completed an underwritten public offering
of 11,804,206 shares of its common stock at a price equal to $31.625 per
share. The net proceeds to the Company, after underwriting discounts and
commissions and other related expenses, were $356.1 million.
 
  On May 3, 1995, the Company completed an underwritten public offering of
10,350,000 shares of its common stock at a price equal to $10.00 per share.
The net proceeds to the Company, after underwriting discounts and commissions
and other related expenses, were $97.3 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 3,881,250 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 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 $.1 million was recorded in fiscal 1995 and fiscal 1996 related to
the Directors Plan.
 
  The per share weighted-average fair value of stock options granted during
fiscal 1996 and fiscal 1997 was $5.93 and $9.49, respectively, on the date of
grant using the Black-Scholes option-pricing model with the following
assumptions for fiscal 1996 and fiscal 1997: expected dividend yield 0%, risk-
free interest rate of 6.3%, expected volatility of the stock price of 41.9%
and an expected life of 5 years.
 
  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 and net income per common
share would have been reduced to the pro forma amounts indicated below:

  Pro forma net income and net income per common share reflects only options
granted in fiscal 1996 and 1997. Therefore, the full impact of calculating
compensation cost for stock options under SFAS No. 123 is not reflected in the
pro forma net income and net income 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 its
employee stock options.

(16) 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.

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 facility was
acquired by the Company as part of its acquisition of Polymetrics on October
2, 1995. 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 (see note
9).
 
  Zimpro is party to certain agreements (entered into in 1990 at the time
Zimpro was acquired from unrelated third parties by the entities from which it
was later acquired by the Company), pursuant to which Zimpro agreed, among
other things, to pay the original sellers a royalty of 3.0% of its annual
consolidated net sales of certain products in excess of $35.0 million through
October 25, 2000. Under certain interpretations of such agreements, with which
the Company disagrees, Zimpro could be liable for such royalties with respect
to the net sales attributable to products, systems and services of certain
defined wastewater treatment businesses acquired by Zimpro or the Company or
the Company's other subsidiaries after May 31, 1996. The defined businesses
include, among others, manufacturing machinery and equipment, and engineering,
installation, operation and maintenance services related thereto, for the
treatment and disposal of waste liquids, toxic waste and sludge. One of the
prior sellers has revealed in a letter to the Company an interpretation
contrary to that of the Company. The Company believes that it would have
meritorious defenses to any claim based upon any such interpretation and would
vigorously pursue the elimination of any threat to expand what it believes to
be its obligations pursuant to such agreements.
 
  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.

                             EMPLOYMENT AGREEMENT


     This Agreement (as it may be amended from time to time hereafter, the
"Agreement"), dated this 25th day of October, 1996, between The Utility Supply
Group, Inc., a Georgia Corporation (the "Company"), and Harry K. Hornish, Jr.
(the "Employee").

     The Employee has been employed as the President of the Company, which is a
wholly-owned subsidiary of USG Holding Corporation (the "Parent"). The Company
is being acquired by United States Filter Corporation ("U.S. Filter") through
the merger of a subsidiary of U.S. Filter (the "Merger Subsidiary") with and
into the Parent pursuant to an Agreement and Plan of Merger, dated as of
September 6, 1996, among the Parent and its then current stockholders, U.S.
Filter and the Merger Subsidiary (the "Merger"). Upon the effectiveness of the
Merger, the separate existence of the Merger Subsidiary shall cease, the Parent
shall continue as the surviving corporation and the Company shall become an
indirect subsidiary of U.S. Filter. The Company desires that the Employee
continue in its employ following the Merger, and the Employee desires to accept
such employment, on the terms and conditions set forth below.

     In consideration of the mutual agreements hereinafter set forth, the
Company and the Employee hereby agree as follows:

     1.   Former Employment Agreement. As a condition precedent to the
          ---------------------------
effectiveness of the Merger, the Employee has tendered his resignation as an
officer and director of the Parent and the Company. The Employee acknowledges
that such resignation constitutes a termination by mutual agreement between the
Company and him pursuant to Section 4(a)(v) of the Employment and
Confidentiality Agreement dated May 31, 1994 between the Company and him (the
"Former Employment Agreement") and that his covenants in Sections 5 and 6 of the
Former Employment Agreement shall survive such termination in accordance with
Section 4(b) thereof and shall not be affected by the Merger or this Agreement,
except as provided in the following sentence. The Company and the Employee agree
that the provisions of Sections 5 and 6 of the Former Employment Agreement shall
be deemed amended to the extent necessary to permit the employee's employment as
contemplated hereby.

     2.   Term and Location.  The Company agrees to employ the Employee, and the
          -----------------
Employee shall serve the Company, for the period beginning upon the
effectiveness of the Merger and ending at the close of business on March 31,
1999 (the "Term"). The Employee shall report to and shall perform the duties
assigned from time to time by the Chairman (the "Chairman") of the Board of
Directors of the Company (the "Board") or his designee, and as are provided in
the Bylaws of the Company as then in effect. The Employee is engaged initially
with the title and functions of Executive Vice President of the Company;
provided, however, that nothing herein shall preclude the Chairman or his
designee from changing the Employee's title and duties, including without
limitation (i) expanding the scope of Employee's duties and responsibilities to
include other businesses heretofore or hereafter conducted or acquired by the
Company, U.S. Filter or any of their respective Affiliates (as defined below) or
(ii) causing the Employee to render services to any Affiliate of U.S. Filter
other than the Company. For purposes of this Agreement, "Affiliate" means with
respect to any person or entity, any other person or entity that, directly or
indirectly, controls, is controlled by or is under common control with, such
person or entity. For purposes of the definition of "Affiliate" the term
"control" (and its derivatives), when used with respect to any specified person
or entity, means the power to direct the management and policies of
<PAGE>
 
such person or entity, directly or indirectly, whether through ownership of
voting securities, by contract or otherwise.

     3.   Duties. During the Term and consistent with his position, the Employee
          ------
shall (i) devote the whole of his working effort, time, attention and skill to
his duties hereunder, (ii) faithfully, loyally and industriously perform such
duties and exercise such powers as may be from time to time assigned to him by
the Chairman, his designee or the By-laws of the Company, (iv) diligently adhere
to and implement the directions and policies of the Chairman, the Company, the
Parent and U.S. Filter, and (v) use his best efforts to promote the interests of
the Company, the Parent, U.S. Filter and their respective Affiliates.

     4.   Compensation, Benefits and other Payments.
          -----------------------------------------
 
          a.   During the Term, the Employee shall be paid a base salary of two
hundred fifty thousand dollars ($250,000) per annum. The Employee's salary shall
be payable in accordance with the employer's then prevailing payroll practices.

          b.   During the Term, the Employee shall be eligible to receive cash
performance bonuses as follows:

               (i)   From the effectiveness of the Merger through December 31,
1996 (the "First Bonus Period"), the Employee shall be eligible to receive a
cash bonus of up to $100,000; provided that the Company attains the objectives
upon which the employee's bonus for calendar year 1996 had been based prior to
the Merger under the Former Employment Agreement.

               (ii)  For the fifteen-month period from January 1, 1997 through
March 31, 1998 (the "Second Bonus Period") and for the twelve-month period from
April 1, 1998 through March 31, 1999 (the "Third Bonus Period" and each of the
First, Second and Third Bonus Periods, a "Bonus Period"), the Employee shall be
eligible to receive a cash bonus of up to $125,000 for the Second Bonus Period
and up to $100,000 for the Third Bonus Period based upon the Company's
attainment during such Bonus Period of specified performance objectives to be
established pursuant to clause (iv) below (the "Company Performance
Objectives").

               (iii) For each of the Second and Third Bonus Periods, the
Employee shall be eligible to receive, in addition to any bonus payable pursuant
to clause (ii) above, a cash bonus of up to a maximum of 35% of his base salary
paid pursuant to Paragraph 4.a., based upon the attainment during such Bonus
Period by the Company, combined with any other distribution business conducted
by or through U.S. Filter or any of its Affiliates that report to the Employee
or for which the Employee otherwise has supervisory responsibility, of specified
performance objectives for such combined businesses to be established pursuant
to clause (iv) below (the "Combined Performance Objectives" and together with
the Company Performance Objectives, the "Performance Objectives").

               (iv)  Subject to the following sentence, the Performance
Objectives that shall apply to each of the Second and Third Bonus Periods shall
be established no later than March 31 of 1997 and 1998, respectively, by good
faith agreement of the parties. In the event that, at any time after the
establishment of Performance Objectives for a Bonus Period, the scope of
Employee's responsibilities and duties are expanded to include businesses other
than that theretofore conducted by the Company, the parties shall adjust the
Performance Objectives applicable to the Bonus Period in which such expansion

                                       2
<PAGE>
 
occurs in such manner as may be appropriate in their good faith judgment such
that the Performance Objectives, as so adjusted, properly reflect such
expansion.

               (v)   Any cash bonus payable to the Employee pursuant to
subparagraph b. above shall be paid by check, or upon the request of the
Employee by direct deposit in an account designated by the Employee for such
purpose, in the amount thereof within 120 days following the end of the
applicable Bonus Period.

          c.   The Employee shall be eligible to participate in U.S. Filters'
1991 Employee Stock Option Plan, subject to all of the applicable terms and
conditions of such Plan.

          d.   The Employee shall be entitled to such vacation time, sick leave,
perquisites of office, fringe benefits, insurance coverage, retirement and
savings plans, other employee benefit and welfare plans, and other terms and
conditions of employment as the Company generally provides to its employees
having rank comparable to the Employee, subject to the applicable provisions of
such arrangement.

     5.   Termination of Employment.  Unless terminated in accordance with the
          -------------------------
provisions of this Paragraph 5, the Company shall continue to employ the
Employee and the Employee shall continue to work for the Company, during the
Term.
 
          a.   The Employee's employment shall terminate automatically upon the
death of the Employee.

          b.   The Company may terminate the Employee's employment if, due to a
physical or mental condition as certified by a physician selected by the
Company, the Employee has not substantially performed his duties hereunder for a
period of ninety (90) consecutive days.

          c.   The Company may terminate the Employee's employment at any time
for cause. For purposes of this Agreement, "cause" shall mean (i) a default or
other breach by the Employee of his obligations or representations under this
Agreement if the Chairman or his designee notifies the Employee of such default
or other breach in writing and the Employee fails to cure such default or other
breach within five days after such written notice has been given; (ii)
misconduct, disloyalty, dishonesty, insubordination or other deliberate act or
omission by the executive detrimental or damaging in a significant way to the
business or the good will of the Company or any of its Affiliates or materially
damaging to the Company's relationships, or the relationships of the Company's
Affiliates, with customers, suppliers or employees; (iii) fraud, embezzlement,
misappropriation, dishonesty or breach of trust; (iv) a felony or a crime of
moral turpitude; (v) a failure or refusal by the Employee to perform any or all
such Employee's duties and responsibilities hereunder if the Chairman or his
designee notifies the Employee of such failure or refusal in writing and the
Employee fails to cure such failure or refusal within five days after such
written notice has been given; or (vi) gross negligence by the Employee in the
performance of any or all of such Employee's duties and responsibilities.

          d.   Upon termination pursuant to subparagraph a. b. or c. above, the
Company shall pay the Employee or his estate any salary earned and unpaid to the

make available to the Company or such Affiliate the sole and exclusive right,
