                   [LOGO OF UNITED STATES FILTER CORPORATION]
                    % CONVERTIBLE SUBORDINATED NOTES DUE 2001
   
  The   % Convertible Subordinated Notes due 2001 (the "Notes") will be
convertible at the option of the holder into shares of common stock, par value
$.01 per share, of the Company (the "Common Stock"), at any time at or prior to
maturity, unless previously redeemed, at a conversion price (the "Conversion
Price") of $       per share (equivalent to a conversion rate of      shares
per $1,000 principal amount of Notes), subject to adjustment in certain events.
Interest on the Notes is payable semi-annually on            and           of
each year, commencing on            . On November 20, 1996, the closing sale
price of the Common Stock of the Company as reported on the New York Stock
Exchange Composite Tape (where it is traded under the symbol "USF") was $33.125
per share.     
 
  The Notes are redeemable, in whole or in part, at the option of the Company,
at any time on or after           , 1999, at the redemption prices set forth
herein, plus accrued and unpaid interest to the date of redemption. The Company
will be required to offer to purchase the Notes upon a Change of Control (as
defined), at 100% of the principal amount thereof, plus accrued and unpaid
interest to the date of purchase.
   
  The Notes are unsecured general obligations of the Company, subordinated in
right of payment to all existing and future Senior Indebtedness (as defined) of
the Company, and are subordinated by operation of law to all liabilities
(including trade payables) of the Company's subsidiaries. The Indenture will
not restrict the incurrence of Senior Indebtedness or other indebtedness by the
Company or its subsidiaries. At September 30, 1996, as adjusted to give effect
to the issuance and sale of the Notes and the application of estimated net
proceeds therefrom and consummation of the acquisition transactions described
herein, the Company would have had approximately $137.9 million of Senior
Indebtedness, and the Company's subsidiaries would have had approximately
$473.0 million of trade payables and accrued liabilities. See "Description of
the Notes."     
 
  Application will be made to list the Notes on the New York Stock Exchange.
 
  Concurrently with this offering (the "Notes Offering"), the Company is
undertaking, pursuant to a separate Prospectus, domestic and international
offerings of shares of Common Stock (the "Common Stock Offerings"). The net
proceeds of the Notes Offering and the Common Stock Offerings are expected to
be used to fund or to repay indebtedness to be incurred to fund the pending
acquisitions by the Company of certain businesses and assets (collectively
referred to as the Water Systems and Manufacturing Group and referred to herein
as "WSMG") of Wheelabrator Technologies Inc. ("WTI") and the businesses of the
Process Equipment Division ("PED") of United Utilities PLC; the balance, if
any, will be used for working capital, capital expenditures and general
corporate purposes, including possible future acquisitions. See "Recent and
Pending Acquisitions" and "Use of Proceeds."
   
SEE "RISK FACTORS" BEGINNING ON PAGE 9 FOR A DISCUSSION OF CERTAIN FACTORS THAT
              SHOULD BE CONSIDERED BY PROSPECTIVE INVESTORS.     
 
THESE SECURITIES  HAVE NOT BEEN APPROVED  OR DISAPPROVED BY THE  SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
  AND EXCHANGE COMMISSION OR ANY  STATE SECURITIES COMMISSION PASSED UPON THE
  ACCURACY  OR  ADEQUACY  OF  THIS  PROSPECTUS.  ANY  REPRESENTATION  TO  THE
   CONTRARY IS A CRIMINAL OFFENSE.

information, including the Selected Consolidated Financial Data, the Company's
Consolidated Financial Statements and Notes thereto and the Unaudited Pro Forma
Combined Financial Information, included or incorporated by reference in this
Prospectus. Except as otherwise specified, all information in this Prospectus

                                  THE COMPANY
 
  The Company is a leading global provider of industrial and municipal water
and wastewater treatment systems, products and services, with an installed base
of systems that the Company believes is one of the largest worldwide. The
Company offers 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. In addition, the
Company has one of the industry's largest networks of sales and service
facilities. The Company capitalizes on its large installed base, extensive
distribution network and manufacturing capabilities to provide customers with
ongoing local service and maintenance. The Company is also a leading provider
of service deionization ("SDI") and outsourced water services, including the
operation of water and wastewater treatment systems at customer sites.
   
  The Company has grown internally and through the strategic acquisition and
successful integration of more than 45 United States based and international
water and wastewater treatment companies since 1991. On a previously reported
basis, the Company's revenues increased to $472.5 million for the fiscal year
ended March 31, 1996 from $41.2 million for the fiscal year ended March 31,
1992, representing a compound annual growth rate of approximately 84%. The
Company's revenues for the fiscal year ended March 31, 1996 would have been
approximately $1.8 billion after giving effect to the completed acquisitions of
Zimpro Environmental, Inc. ("Zimpro") and Davis Water & Waste Industries, Inc.
("Davis") and including, on a pro forma basis, the pending acquisitions of WSMG
and PED and the recent acquisitions of WaterPro Supplies Corporation
("WaterPro") and The Utility Supply Group, Inc. ("USG") as if such acquisitions
were completed at the beginning of such year.     
 
  Global population growth, economic expansion, scarcity of available water
resources, heightened public concern about water quality and growing regulatory
requirements have resulted in: (i) continued growth of the multibillion dollar
water and wastewater treatment industry; and (ii) heightened demand for
increasingly complex water and wastewater treatment systems. The water
treatment industry is highly fragmented, with numerous regional participants
who provide customers with a limited range of water and wastewater treatment
solutions. The Company differentiates itself from competitors by serving as a
single-source water and wastewater treatment provider capable of designing,
manufacturing, operating, financing and maintaining water and wastewater
systems on a local basis for industrial and municipal customers. The Company's
customer base includes a broad range of major industrial customers, which
require treated water as a necessary component of many products and industrial
processes, and municipalities, which treat water and wastewater for their
communities. Industrial customers include Chinese Petroleum, Coca-Cola, Dow
Chemical, General Motors, Hyundai, Intel, Johnson & Johnson, Merck, Procter &
Gamble and Samsung. Municipal customers include the Cities of Los Angeles,
Minneapolis-St. Paul and St. Louis.

  In order to achieve earnings growth and expand its operations to enhance its
position as a leading global single-source provider of water and wastewater
treatment systems and services, the Company has developed the following
strategy:
 
  .Provide single-source water and wastewater treatment solutions to
   industrial and municipal customers
 
  .Pursue acquisitions that provide a strategic fit and contribute to revenue
   and earnings growth
 
  .Realize synergies and economies of scale from acquisitions
 
  .Expand global market presence, especially in the Pacific Rim region
 
  .Expand penetration of the municipal market
 
  .Capitalize on distribution strength to enhance local sales and service
   capabilities
     
  .Capitalize on outsourcing and privatization opportunities     
 
RECENT AND PENDING ACQUISITIONS
 
  The Company has become a leading single-source provider of cost-effective
water and wastewater treatment systems primarily through acquisitions of
businesses that have expanded the Company's geographic presence, industries
served, installed base and range of products and technologies. The Company's
acquisition strategy has also recently focused on establishing the Company as a
leading distributor of water and wastewater distribution products and services
to the industrial and municipal markets.
   
  The Company has entered into a definitive agreement with WTI to acquire WSMG
for $369.6 million in cash, subject to possible adjustment. The Company has
also entered into a definitive agreement to acquire PED from United Utilities
PLC for (Pounds)125.5 million in cash and stock, subject to possible
adjustment. Additionally, the Company has acquired Davis in exchange for
4,187,349 shares of Common Stock, WaterPro in exchange for 3,201,507 shares of
Common Stock and USG in exchange for 771,157 shares of Common Stock.     
 
 WATER SYSTEMS AND MANUFACTURING GROUP
 
  WSMG provides a broad range of water and wastewater treatment products and
technologies, as well as other environmental products, worldwide. For the
fiscal year ended December 31, 1995, WSMG generated approximately $452.1
million of revenues, of which approximately 56% were attributable to sales in
North America, with the remainder generated principally in Europe, the Pacific
Rim and the Middle East.
 
  The Company believes that the acquisition of WSMG will significantly broaden
the Company's product offerings, technological capabilities and municipal
market penetration. WSMG is also expected to provide the Company with cross-
selling opportunities as well as opportunities to rationalize operations and
increase asset utilization. In addition, the Company believes that WSMG will
provide it with the infrastructure required to capitalize on opportunities in
the Pacific Rim and further strengthens the Company's presence in European
markets.
       
       
 PROCESS EQUIPMENT DIVISION
 
  PED is a leading manufacturer and distributor of a broad range of water and
wastewater treatment equipment sold primarily to the municipal market. For the
fiscal year ended March 31, 1996, PED generated approximately $267.4 million of
revenues, of which approximately 60% were attributable to sales in North
America, with the remainder generated principally in Europe, Latin America and
the Pacific Rim. For the fiscal year ended March 31, 1996, a majority of PED's
revenues were attributable to sales in the municipal market.
 
                                       4
<PAGE>
 
 
  The Company believes that the acquisition of PED will significantly
strengthen the Company's municipal water and wastewater treatment capabilities
and provide the Company with opportunities to rationalize operations and
increase asset utilization. Additionally, the Company believes that
opportunities exist to expand PED's industrial sales by distributing PED's
products through the Company's extensive network of sales and service
facilities.
 
 DISTRIBUTION ACQUISITIONS
   
  The Company believes that the recent acquisitions of Davis, WaterPro and USG
establish the Company as a leading distributor of water and wastewater
distribution products and services to the industrial and municipal markets.
Through the addition of 105 distribution facilities, these recent acquisitions
provide the Company with a strategically important local sales and service
presence in the markets being served. Additionally, each of Davis, WaterPro and
USG benefits from established relationships with municipalities. The Company
believes that these relationships will provide it with an effective means of
penetrating the municipal market and permit the Company to capitalize on
opportunities to retrofit, replace and repair aging water infrastructure in the
United States. The Company intends to utilize its distribution channels, local
presence and single-source capabilities to sell its extensive product line,
including capital equipment, replacement parts, and services, to customers in
both the industrial and municipal markets. As a result, the Company believes
that its distribution infrastructure will provide a mechanism to leverage its
manufacturing capabilities and technology base. The Company also believes that
the distribution acquisitions will provide cost-saving opportunities through
rationalization of overhead expenses and realization of economies of scale and
operating efficiencies.

                                    plus accrued and unpaid interest to the
                                    date of purchase.

 Subordination....................  The Notes will be general, unsecured
                                    obligations of the Company, subordinated in
                                    right of payment to all existing and future
                                    Senior Indebtedness of the Company and will
                                    be structurally subordinated to all
                                    liabilities (including trade payables) of
                                    the Company's Subsidiaries. At September
                                    30, 1996, as adjusted to give effect to the
                                    issuance and sale of the Notes and the
                                    application of the estimated net proceeds
                                    therefrom and consummation of the
                                    acquisition transactions described herein,
                                    the Company would have aggregate Senior
                                    Indebtedness of approximately
                                    $137.9 million and the Company's
                                    Subsidiaries would have had approximately
                                    $473.0 million of trade payables and
                                    accrued liabilities. The Indenture will not
                                    restrict the incurrence of Senior
                                    Indebtedness or other indebtedness by the
                                    Company or any of its Subsidiaries.

 Use of Proceeds..................  The net proceeds from the Notes Offering,
                                    together with the net proceeds from the
                                    Common Stock Offerings, will be used to
                                    fund or to repay indebtedness incurred to
                                    fund the pending acquisitions by the
                                    Company of WSMG and PED; the balance, if
                                    any, will be used for working capital,
                                    capital expenditures and general corporate
                                    purposes, including possible future
                                    acquisitions. If the net proceeds from the
                                    Notes Offering and the Common Stock
                                    Offerings are not available, the Company
                                    expects to fund the acquisitions of WSMG
                                    and PED from borrowings under committed
                                    bank credit facilities. See "Recent and
                                    Pending Acquisitions" and "Use of

           SUMMARY UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
   
  The following data present selected historical consolidated financial data of
the Company (restated to reflect the acquisitions of Zimpro and Davis, which
were accounted for as poolings of interests) as of the date and for the periods
presented, and As Adjusted to give effect to: (i) the recent acquisitions of
WaterPro and USG and the pending acquisitions of WSMG and PED as if they had
been consummated as of the beginning of the respective periods presented (in
the case of Statement of Operations Data and Other Data) and as of September
30, 1996 (in the case of Balance Sheet Data); and (ii) the assumed borrowings
under bank credit facilities of approximately $541.0 million to fund the cash
portion of the consideration for such acquisitions and estimated transaction
costs. The As Further Adjusted column gives effect to: (i) the sale by the
Company of the Notes and the anticipated application of the net proceeds
therefrom; (ii) the sale by the Company of 10,000,000 shares of Common Stock in
the Common Stock Offerings at an assumed public offering price of $33.125 per
share and the anticipated application of the net proceeds therefrom; and
(iii) the conversion of the Company's $60.0 million aggregate principal amount
of 5% Convertible Subordinated Debentures due 2000 into 4,390,000 shares of
Common Stock.     
   
  The pro forma data is derived from the historical financial statements of the
Company, WSMG, PED, WaterPro and USG giving effect to such acquisitions under
the purchase method of accounting and based on assumptions and adjustments
described under the caption "Unaudited Pro Forma Combined Financial
Information." The pro forma adjustments are estimated and may differ from the
actual adjustments when they become known. The pro forma data does not reflect
certain cost savings that management believes may be realized following the
acquisitions, through rationalization of operations and economies of scale. See
"Unaudited Pro Forma Combined Financial Information."

(3) "EBITDA" consists of operating income plus depreciation and amortization.
    EBITDA data is presented because such data is used by certain investors to
    determine the Company's ability to meet debt service requirements. The
    Company considers EBITDA to be an indicative measure of the Company's
    operating performance. However, such information should not be considered
    as an alternative to net income, operating profit, cash flows from
    operations, or any other operating or liquidity performance measure
    prescribed by generally accepted accounting principles. The EBITDA measure
    presented by the Company may not be comparable to similarly titled measures
    used by other companies.

                                 RISK FACTORS
 
  Prospective investors should consider carefully the following factors
relating to the businesses of the Company, WSMG, PED, WaterPro and USG and the
sale of the Notes, together with the other information and financial data
included or incorporated by reference in this Prospectus, before acquiring
Notes offered hereby. Information contained or incorporated by reference in
this Prospectus contains "forward-looking statements" which can be identified
by the use of forward-looking terminology such as "believes," "contemplates,"
"expects," "may," "will," "should," "would" or "anticipates" or the negative
thereof or other variations thereon or comparable terminology, or by
discussions of strategy. No assurance can be given that the future results
covered by the forward-looking statements will be achieved. The following
matters constitute cautionary statements identifying important factors with
respect to such forward-looking statements, including certain risks and
uncertainties, that could cause actual results to vary materially from the
future results covered in such forward-looking statements. Other factors could
also cause actual results to vary materially from the future results covered
in such forward-looking 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 45
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.
   
  Consummation of the pending acquisitions of each of WSMG and PED are subject
to the satisfaction of certain conditions, including expiration or termination
of applicable waiting periods under the United States Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended. The waiting period with
respect to WSMG has expired. There can be no assurance that the pending
acquisition of PED will not be challenged on antitrust grounds, or if
challenged, that the Company will prevail. There can also be no assurance as
to whether or when the Company's pending acquisitions of WSMG and PED will be
completed. The net proceeds to the Company of the Offerings and the Notes
Offering are expected to be used to fund or to repay indebtedness used to fund
these pending acquisitions; the balance, if any, will be used for working
capital, capital expenditures and general corporate purposes, including
possible future acquisitions. If either or both of the pending acquisitions of
WSMG and PED are not completed, the net proceeds of the Offerings and the
Notes Offering not used for those acquisitions will be added to working
capital. See "Recent and Pending Acquisitions" and "Use of Proceeds."     
       
       
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. In particular, the purchase price for the
pending acquisition by the Company of PED is (Pounds)125.5 million, comprised
of approximately (Pounds)100.5 million in cash and (Pounds)25.0 million in
shares of Common Stock. The Company has entered into a forward contract
pursuant to which it is obligated to purchase 100.0 million British pounds
sterling for approximately $159.3 million at any time between December 16,
1996 and February 14, 1997, for the purpose of hedging the cash portion of the
purchase price of     
 
                                       9
<PAGE>
 
   
its acquisition of PED. With respect to the remaining (Pounds)0.5 million cash
portion of the consideration and the (Pounds)25.0 million in shares of Common
Stock, to the extent the value of the United States dollar declines relative
to pounds sterling prior to the closing of the acquisition, the cost to the
Company of acquiring PED would increase. In addition, if the acquisition of
PED is not consummated, or the acquisition is consummated after February 14,
1997, the Company would be at risk with respect to the (Pounds)100.0 million
it purchased pursuant to such forward contract to the extent that the value of
the pound sterling decreases relative to the value of other currencies.     
 
RELIANCE ON KEY PERSONNEL
   
  The Company's operations are, and will, after consummation of the Company's
pending acquisitions, be 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.
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, and will, after
consummation of the Company's pending acquisitions, be 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, and will, after consummation of the Company's pending
acquisitions, be 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 the acquisitions of Davis, WaterPro and USG, the sale
of water and wastewater distribution equipment and supplies is a significant
component of the Company's business. See "Recent and Pending Acquisitions."
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     
 
                                      10
<PAGE>
 
   
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.     
 
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 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 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 the Company's recent and pending acquisitions will increase
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     
 
                                      11
<PAGE>
 
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. See
"Recent and Pending Acquisitions" and "Business."
   
  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.     
 
SHARES ELIGIBLE FOR FUTURE SALE
   
  The market price of the Common Stock could be adversely affected by the
availability for public sale of shares held on November 10, 1996 by security
holders of the Company, including: (i) up to 3,750,093 shares which may be
delivered by Laidlaw Inc. or its affiliates ("Laidlaw"), at Laidlaw's option
in lieu of cash, at maturity pursuant to the terms of 5 3/4% Exchangeable
Notes due 2000 of Laidlaw (the amount of shares or cash delivered or paid to
be dependent within certain limits upon the value of the Common Stock at
maturity); (ii) 7,636,363 shares issuable upon conversion of the Company's 6%
Convertible Subordinated Notes due 2005 at a conversion price of $18.33 per
share of Common Stock; (iii)       shares issuable upon conversion of the
Notes at a conversion price of $      per share of Common Stock; (iv)
2,908,171 outstanding shares that are currently registered for sale under the
Securities Act of 1933, as amended (the "Securities Act"), pursuant to two
shelf registration statements; and (v) 7,036,939 shares which are subject to
agreements pursuant to which the holders have certain rights to request the
Company to register the sale of such holders' Common Stock under the
Securities Act and/or, subject to certain conditions, to include certain
percentages of such shares in other registration statements filed by the
Company (1,980,000 of which shares also may be sold from time to time by the
holder thereof pursuant to Rule 144 under the Securities Act). The shares
referred to in clause (v) include up to 845,794 shares that may be sold by
Selling Stockholders upon exercise of the U.S. Underwriters' over-allotment
option. In addition, the Company has registered for sale under the Securities
Act 5,777,380 shares which may be issuable by the Company from time to time in
connection with acquisitions of businesses from third parties.     
 
SUBORDINATION
   
  The Notes will be subordinated in right of payment to all existing and
future Senior Indebtedness and will be structurally subordinated to all
liabilities (including trade payables) of the Company's subsidiaries. The
Indenture will not restrict the incurrence of Senior Indebtedness or other
indebtedness by the Company or its subsidiaries. At September 30, 1996, the
Company would have had approximately $137.9 million of Senior Indebtedness
outstanding after giving effect to: (i) the acquisitions of WSMG, PED, USG and
WaterPro; (ii) the sale of the Notes and the anticipated application of the
net proceeds therefrom; (iii) the sale by the Company in the Common Stock
Offerings of 10,000,000 shares of Common Stock at an assumed public offering
price of $33.125 per share (based on the closing sale price per share of
Common Stock on November 20, 1996 as reported on the New York Stock Exchange
Composite Tape) and the anticipated application of the net proceeds     
 
                                      12
<PAGE>
 
therefrom; and (iv) the conversion of the Company's 5% Convertible Subordinated
Debentures due 2000 into 4,390,000 shares of Common Stock. By reason of such
subordination of the Notes, in the event of the insolvency, bankruptcy,
liquidation, reorganization, dissolution or winding up of the business of the
Company or upon a default in payment with respect to any indebtedness of the
Company or an event of default with respect to such indebtedness resulting in
the acceleration thereof, the assets of the Company will be available to pay
the amounts due on the Notes only after all Senior Indebtedness has been paid
in full. The Notes will rank pari passu with other unsecured, subordinated
obligations of the Company, including the Company's 6% Convertible Subordinated
Notes due 2005. See "Description of the Notes--Subordination."
   
  The Company conducts its operations through its subsidiaries. Accordingly,
the Company's ability to meet its cash obligations is dependent in part upon
the ability of its subsidiaries to make cash distributions to the Company. The
ability of its subsidiaries to make distributions to the Company is and will
continue to be restricted by, among other limitations, applicable provisions of
the laws of national or state governments and contractual provisions. The
Indenture will not limit the ability of the Company's subsidiaries to agree to
be bound by such contractual restrictions in the future. Although the
jurisdictions in which the Company's subsidiaries now conduct substantially all
of their business generally do not restrict the removal or conversion of local
or foreign currency, such restrictions, if enacted, could create substantial
barriers to the conversion or repatriation of funds, and such restrictions
could adversely affect the Company's ability to meet its debt service and other
liquidity requirements. In addition, various jurisdictions place limits on the
amount and source of dividends that may be paid by companies under certain
circumstances. The right of the Company to participate in the assets of any
subsidiary (and thus the ability of holders of the Notes to benefit indirectly
from such assets) are generally subject to the prior claims of creditors,
including trade creditors, of that subsidiary except to the extent that the
Company is recognized as a creditor of such subsidiary, in which case the
Company's claims would still be subject to any security interest of other
creditors of such subsidiary. The Notes, therefore, will be subordinated by
operation of law to creditors, including trade creditors, of subsidiaries of
the Company with respect to the assets of the subsidiaries against which such
creditors have a claim. At September 30, 1996, as adjusted to give effect to
the acquisitions of WSMG, PED, WaterPro and USG, the Company's subsidiaries
would have had approximately $473.0 million of trade payables and accrued
liabilities.     
 
ABSENCE OF EXISTING MARKET FOR NOTES
   
  The Notes will constitute a new issue of securities with no established
trading market. Application will be made to list the Notes on the New York
Stock Exchange. The Company has been advised by the Underwriters that,
following completion of the offering of the Notes, they presently intend to
make a market in the Notes. However, the Underwriters are not obligated to do
so and any marketmaking activities may be discontinued at any time without
notice. In addition, such marketmaking activities will be subject to the limits
imposed by the Exchange Act. No assurance can be given that an active trading
market for the Notes will develop or, if such market develops, as to the
liquidity or sustainability of such market. If a trading market does not
develop or is not maintained, holders of the Notes may experience difficulty in
reselling the Notes or may be unable to sell them at all. If a market for the
Notes develops, any such market may be discontinued at any time. If a public
trading market develops for the Notes, future trading prices of the Notes will
depend on many factors, including, among other things, prevailing interest
rates, the Company's results of operations and the market for similar
securities. Depending on prevailing interest rates, the market for similar
securities and other factors, including the financial condition of the Company,
the Notes may trade at a discount from their principal amount.

                        RECENT AND PENDING ACQUISITIONS
   
  The Company has become a leading single-source provider of cost-effective
water and wastewater treatment systems primarily through acquisitions of
businesses that have expanded the Company's geographic presence, industries
served, installed base, and range of products and technologies. The Company's
pending acquisitions of WSMG and PED are expected to provide the Company with
important products and technologies which enhance the Company's single-source
provider capabilities. The Company believes that these acquisitions will also
significantly expand the Company's municipal and wastewater treatment
capabilities and international presence, particularly in the Pacific Rim and
Europe. The Company is negotiating the possible formation of a joint venture
with WTI (the "Joint Venture") to develop, finance, own and operate water and
wastewater treatment facilities for both industrial and municipal customers in
North America. See "--Possible Joint Venture."     
   
  The Company's acquisition strategy has also recently focused on establishing
the Company as one of the industry's leading distributors of water and
wastewater distribution products and services to both the industrial and
municipal markets. The recent acquisitions of Davis, WaterPro and USG are
expected to provide the Company with a platform to: (i) enhance the Company's
local sales and service infrastructure; (ii) penetrate the municipal segment
of the water and wastewater treatment market by capitalizing on each
distribution company's long-term municipal relationships; (iii) leverage the
Company's manufacturing capabilities and technology base; and (iv) capitalize
on efficiencies from consolidation of operations and economies of scale. In
addition, the Company believes that these distribution acquisitions will
permit the Company to capitalize on opportunities to retrofit, replace and
repair aging water infrastructure in the United States.     
 
  Together, these recent and pending acquisitions are expected to distinguish
further the Company as a leading single-source provider capable of designing,
manufacturing, operating, financing and maintaining water and wastewater
treatment systems on a local basis for industrial and municipal customers
worldwide.
 
WATER SYSTEMS AND MANUFACTURING GROUP
 
  On September 14, 1996, the Company entered into a definitive agreement to
acquire WSMG from WTI for $369.6 million in cash, subject to possible post-
closing adjustment. WSMG provides a broad range of water and wastewater
treatment products and technologies, as well as other environmental products,
worldwide. As of October 4, 1996, WSMG had 1,993 employees and 57 facilities
located in 17 countries.
 
  For the fiscal year ended December 31, 1995, WSMG generated approximately
$452.1 million of revenues, of which approximately 56% were attributable to
sales in North America, with the remainder generated principally in Europe,
the Pacific Rim and the Middle East.
 
  The Company believes that the acquisition of WSMG will significantly broaden
the Company's product offerings, technological capabilities and municipal
market penetration, WSMG is also expected to provide the Company with cross-
selling opportunities as well as opportunities to rationalize operations and
increase asset utilization. In addition, the Company believes that the
acquisition of WSMG will provide it with the infrastructure required to
capitalize on increasing opportunities in the Pacific Rim and will further
strengthen the Company's presence in European markets. A description of
certain of the WSMG business units follows.

  The Company anticipates that the acquisition of WSMG will be completed by
early December 1996, although there can be no assurance that the acquisition
will be consummated at such time or at all.     
          
POSSIBLE JOINT VENTURE     
   
  The Company and WTI are negotiating the possible formation of the Joint
Venture to develop, finance, own and operate water and wastewater treatment
facilities for both industrial and municipal customers in North America. It is
expected that the operating strategy for the Joint Venture, if formed, would
be to offer customers: (i) turnkey operation, including system design,
manufacture, operation and maintenance on a local basis; (ii) warrantied
performance; (iii) potential cost savings; and (iv) customized financing
options. There can be no assurance as to whether or when or on what specific
terms the Joint Venture will actually be formed. The Company is currently a
50% owner of Treated Water Outsourcing, a Nalco/U.S. Filter Joint Venture
("TWO"), which focuses on the outsourcing of industrial customers' water
treatment needs.     
 
 
PROCESS EQUIPMENT DIVISION
   
  On October 7, 1996, the Company entered into a definitive agreement to
acquire PED from United Utilities PLC for (Pounds)125.5 million, comprised of
approximately (Pounds)100.5 million in cash and (Pounds)25.0 million in shares
of Common Stock, subject to possible post-closing adjustment. PED is a leading
manufacturer and distributor of water and wastewater treatment equipment
primarily to the municipal market. As of June 30, 1996, PED had approximately
1,935 employees and 17 facilities located in seven countries.     
 
  For the fiscal year ended March 31, 1996, PED generated approximately $267.4
million of revenues, of which approximately 60% were attributable to sales in
North America, with the remainder generated principally in Europe, Latin
America and the Pacific Rim. For the fiscal year ended March 31, 1996, a
majority of PED's revenues were attributable to sales in the municipal market.
 
  The Company believes that the acquisition of PED will significantly
strengthen the Company's municipal water and wastewater treatment capabilities
and provide the Company with opportunities to rationalize operations and
increase asset utilization. Additionally, the Company believes that
opportunities exist to expand PED's industrial sales by distributing PED's
products through the Company's sales, service and distribution facilities. A
description of certain PED business units follows.
 
  Envirex. Envirex manufactures wastewater treatment equipment, including
screening, grit removal, biological treatment and solids collection equipment.
The Company believes that Envirex has one of the largest number of wastewater
treatment units installed worldwide as well as one of the broadest product
lines in the wastewater equipment market. The Company believes that by
integrating and rationalizing Envirex's product lines with the Company's
existing wastewater products, it will enhance its municipal wastewater product
lines, which in turn will enable the Company to establish more effective
municipal sales channels. The Company also believes that it may be able to
increase Envirex's sales to industrial markets through the Company's
industrial distribution channels.
 
  Wallace & Tiernan. Wallace & Tiernan is one of the world leaders in the
manufacture of water and wastewater disinfection systems and components. The
Company believes that significant opportunities exist to use Wallace &
Tiernan's global presence and large installed base to cross-sell certain of
the Company's other products and services. Additionally, Wallace & Tiernan's
large installed base is expected to continue to generate revenue from the sale
of replacement parts and services.
 
  Edwards & Jones/Asdor. Edwards & Jones designs, manufactures and installs
biosolids handling equipment primarily for the municipal markets in Europe and
the Pacific Rim, while Asdor performs the same functions in North America. The
Company believes that the acquisition of Edwards & Jones will provide the
Company with a critical mass of wastewater expertise in the European market
and a channel to integrate further the Company's existing wastewater expertise
into its European operations.
 
  General Filter/Acumem. General Filter is a leading provider of pre-treatment
equipment, granular media filtration systems and microfiltration systems
primarily to the municipal water markets in North America.
 
                                      16

  The Company anticipates that the acquisition of PED will be completed by the
end of December 1996, although there can be no assurance that the acquisition
will be consummated at such time or at all.
 
DISTRIBUTION ACQUISITIONS
   
  The Company believes that the recent acquisitions of Davis, WaterPro and USG
establish the Company as a leading distributor of water and wastewater
distribution products and services to the industrial and municipal markets.
Through the addition of 105 distribution facilities, these recent acquisitions
provide the Company with a strategically important local sales and service
presence in the markets being served. Additionally, each of Davis, WaterPro
and USG benefits from established relationships with municipalities. The
Company believes that these relationships will provide it with an effective
means of penetrating the municipal market and permit the Company to capitalize
on opportunities to retrofit, replace and repair aging water infrastructure in
the United States. The Company intends to utilize its distribution channels,
local presence and single-source capabilities to sell its extensive product
line, including capital equipment, replacement parts, and services to both the
industrial and municipal markets. As a result, the Company believes that its
distribution infrastructure will provide a mechanism to leverage its
manufacturing capabilities and technology base. The Company also believes that
the distribution acquisitions will provide cost-saving opportunities through
rationalization of overhead expenses and realization of economies of scale and
operating efficiencies.     
 
  Davis Water and Waste Industries, Inc. In August 1996, the Company completed
the acquisition of Davis, a leading distributor of water and wastewater
distribution products and services to the industrial and municipal markets.
Davis also designs, engineers, manufactures and installs water and wastewater
treatment and pumping equipment. Davis has 32 distribution facilities located
primarily in the southeastern United States which service more than 25,000
customers. For the fiscal year ended April 30, 1996, Davis generated
approximately $226.5 million of revenues, of which approximately $178.2
million, or 79%, were attributable to the sale of distribution products and
services, and approximately $48.3 million, or 21%, were attributable to
manufacturing, installing, processing and servicing water and wastewater
treatment and pumping equipment. The acquisition of Davis provides the Company
with a significant distribution channel in the southeastern United States to
market its line of products and services.
   
  WaterPro Supplies Corporation. In October 1996, the Company completed the
acquisiton of WaterPro, a leading distributor of water and wastewater
distribution products and services to the industrial and municipal markets, in
exchange for 3,201,507 shares of Common Stock (including the repayment of
approximately $67.9 million in outstanding WaterPro debt with shares of Common
Stock). WaterPro serves approximately 18,000 customers through its 43
distribution facilities in 18 states, located primarily in the midwestern and
mid-Atlantic United States. For the period April 7, 1995 to December 31, 1995,
WaterPro generated approximately $187.5 million of revenues. The acquisition
of WaterPro increases the Company's distribution presence in the midwestern
and mid-Atlantic United States and expands the Company's presence in the
municipal market.     
   
  The Utility Supply Group, Inc. In October 1996, the Company completed the
acquisition of USG, a leading distributor of water and wastewater distribution
products and services to the municipal market, in exchange for 771,157 shares
of Common Stock, subject to adjustment. USG serves approximately 6,000
customers through 30 distribution and sales facilities, located primarily in
Texas, Florida and California. For the fiscal year ended December 31, 1995,
USG generated revenues of approximately $156.8 million. The acquisition of USG
increases the Company's distribution presence in the western, southern and
southeastern United States and expands the Company's municipal customer base.

                                USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the Notes are estimated to
be $194.9 million ($224.1 million if the Underwriters' over-allotment option
were exercised in full), after deducting estimated underwriting discounts and
commissions and estimated offering expenses. The net proceeds to the Company
from the Common Stock Offerings are estimated to be $318.1 million ($338.9
million if the underwriters' over-allotment option were exercised in full)
based on the closing sale price per share of Common Stock on November 20, 1996
as reported on the New York Stock Exchange Composite Tape and after deducting
estimated underwriting discounts and commissions and estimated offering
expenses. The aggregate net proceeds of the Notes Offering and the Common
Stock Offerings are expected to be used to fund or to repay indebtedness used
to fund the pending acquisition by the Company of WSMG and to fund or to repay
indebtedness used to fund the cash portion of the consideration for the
pending acquisition by the Company of PED, in each case depending on whether
such acquisition is completed after or before the consummation of the Notes
Offering and the Common Stock Offerings. The purchase price for WSMG is $369.6
million in cash, subject to possible adjustment, and the cash portion of the
purchase price for PED is approximately (Pounds)100.5 million, subject to
possible adjustment. The Company has entered into a forward contract pursuant
to which it is obligated to purchase (Pounds)100.0 million for approximately
$159.3 million at any time between December 16, 1996 and February 14, 1997.
The balance of the net proceeds from the Notes Offering and the Common Stock
Offerings, if any, will be used for working capital, capital expenditures and
general corporate purposes, including possible future acquisitions. If either
or both of the WSMG acquisition and the PED acquisition are not completed, the
net proceeds from the Notes Offering and the Common Stock Offerings not used
for such acquisitions will be added to working capital. See "Recent and
Pending Acquisitions." Consummation of the Notes Offering is not a condition
to consummation of the Common Stock Offerings, and consummation of the Common
Stock Offerings is not a condition to consummation of the Notes Offering.     
   
  To the extent that net proceeds from the Notes Offering and the Common Stock
Offerings are not available or are insufficient, the Company expects to obtain
all or part of the funds necessary to complete the WSMG acquisition and the
PED acquisition from borrowings under bank credit facilities. The Company has
received a commitment letter from The First National Bank of Boston pursuant
to which, subject to the satisfaction of various conditions, credit facilities
(the "Committed Credit Facilities") of up to $700.0 million would be made
available to the Company to finance acquisitions (including the WSMG
acquisition and the PED acquisition), to refinance any borrowings under the
Company's current credit agreement, and for working capital and other general
corporate purposes. Borrowings under the Committed Credit Facilities would
bear interest at variable rates of up to 2.25% above certain Eurocurrency
rates or 0.50% above The First National Bank of Boston's base rate and have a
five year maturity. The Company anticipates that, following completion of the
Notes Offering and the Common Stock Offerings, its bank credit facilities will
be reduced to a level that the Company considers appropriate for its working
capital and other needs.     
 
  Pending utilization as described above, the net proceeds from the Notes
Offering and the Common Stock Offerings will be invested in short-term,
interest-bearing obligations.

                                DIVIDEND POLICY
 
  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 The First National Bank of Boston and First Interstate
Bank of California, no dividends may be paid on the Common Stock without the
consent of those banks.

              UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION
   
  The following Unaudited Pro Forma Combined Financial Information presents
the Pro Forma Combined Balance Sheet at September 30, 1996, giving effect to
the acquisitions of WaterPro and USG and the pending acquisitions of WSMG and
PED as if they had been consummated on that date. Also presented are the Pro
Forma Combined Statements of Operations for the fiscal year ended March 31,
1996 and the six months ended September 30, 1996, after giving effect to the
recent acquisitions of WaterPro and USG and the pending acquisitions of WSMG
and PED as if they had been consummated as of the beginning of the respective
periods presented. The Company's and PED's fiscal years end on March 31 and
WSMG's, WaterPro's and USG's fiscal years end on December 31. The Pro Forma
Balance Sheet combines the respective balance sheets of the Company, WSMG,
PED, WaterPro and USG as of September 30, 1996. The Pro Forma Statement of
Operations for the year ended March 31, 1996 combines the results of the
Company and PED for such year with the results of WSMG, WaterPro and USG for
the year ended December 31, 1995, and the Pro Forma Statement of Operations
for the six months ended September 30, 1996 combines the results of each of
the Company, WSMG, PED, WaterPro and USG for such six month period. All
Company historical consolidated financial data has been restated to reflect
the acquisitions in May 1996 and August 1996 of Zimpro and Davis,
respectively, which acquisitions have been accounted for as poolings of
interests.     
   
  The As Adjusted column gives effect to: (i) the recent acquisitions of
WaterPro and USG and the pending acquisitions of WSMG and PED; and (ii) the
assumed borrowings under the Committed Credit Facilities of approximately
$541.0 million to fund the cash portion of the consideration for such
acquisitions and estimated transaction costs. The As Further Adjusted column
gives effect to: (i) the sale by the Company of the Notes and the anticipated
application of the net proceeds therefrom to the reduction of amounts
outstanding under the Committed Credit Facilities; (ii) the sale by the
Company of 10,000,000 shares of Common Stock in the Offerings at an assumed
public offering price of $33.125 per share and the anticipated application of
the net proceeds therefrom to the reduction of amounts outstanding under the
Committed Credit Facilities; and (iii) the conversion of the Company's $60.0
million aggregate principal amount of 5% Convertible Subordinated Debentures
due 2000 into 4,390,000 shares of Common Stock.     
   
  The pro forma data is based on the historical combined statements of the
Company, WSMG, PED, WaterPro and USG giving effect to such acquisitions under
the purchase method of accounting and the assumptions and adjustments (which
the Company believes to be reasonable) described in the accompanying Notes to
Unaudited Pro Forma Combined Financial Information. Under the purchase method
of accounting, assets acquired and liabilities assumed will be recorded at
their estimated fair value at the date of acquisition. The pro forma
adjustments set forth in the following Unaudited Pro Forma Combined Financial
Information are estimated and may differ from the actual adjustments when they
become known, however, no material differences are anticipated.     
   
  The historical financial statements of PED were prepared in accordance with
UK GAAP, which differs in certain respects from US GAAP. The historical PED
financial statements included in the following Unaudited Pro Forma Combined
Financial Information have been restated to reflect PED's financial position
and results of operations in accordance with US GAAP.     
   
  The following Unaudited Pro Forma Combined Financial Information does not
reflect certain cost savings that management believes may be realized
following the acquisitions. These savings are expected to be realized
primarily through rationalization of operations and implementation of strict
cost controls and standardized operating procedures. Additionally, the Company
believes the acquisitions will enable it to continue to achieve economies of
scale, such as enhanced purchasing power and increased asset utilization.
There can be no assurance that the acquisitions of WSMG or PED will be
consummated.     
 
  The pro forma data is provided for comparative purposes only. It does not
purport to be indicative of the results that actually would have occurred if
the acquisitions of WSMG, PED, WaterPro and USG had been consummated on the
dates indicated or that may be obtained in the future. The Unaudited Pro Forma
Combined Financial Information should be read in conjunction with the notes
thereto, the audited financial statements of WSMG, PED and WaterPro and the
notes thereto, included elsewhere herein, and the Company's Consolidated
Financial Statements and Notes thereto, included elsewhere herein.

  In addition to the purchase prices described above, the Company assumed
long-term indebtedness of approximately $22,000,000 ($19,475,000 at
September 30, 1996) and $67,935,000 ($58,679,000 at September 30, 1996) in
connection with the acquisitions of USG and WaterPro, respectively. The
$67,935,000 of indebtedness related to WaterPro was repaid with shares of
Common Stock concurrently with the closing of such acquisition.     
   
  The cash portion of the purchase price for PED is approximately
(Pounds)100,500,000. The Company has entered into a forward contract pursuant
to which it has the obligation to purchase (Pounds)100,000,000 for
approximately $159,250,000 at any time between December 16, 1996 and February
14, 1997. The remaining (Pounds)500,000 cash portion of the consideration and
the (Pounds)25,000,000 in shares of Common Stock are based on exchange rates
for British pounds sterling as of November 20, 1996. The estimated shares of
Common Stock to be issued is also based on an assumed price per share of
$33.125, the closing price of the Common Stock on the New York Stock Exchange
on November 20, 1996.     
   
  The estimated net book value, as adjusted, of USG, WaterPro, WSMG and PED
and the estimated fair value of their net assets as of the closing date are
assumed to be $6,142,000, $10,911,000, $256,482,000 and $101,764,000,
respectively. PED's estimated fair value of net assets excludes the net loan
payable of PED to its parent company of $316,980,000, which will be
contributed to PED's shareholders' equity (negative $215,216,000 at
September 30, 1996) by such parent company. The aggregate difference between
the estimated equity purchase prices and the estimated fair values of the
identified net assets of USG, WaterPro, WSMG and PED is approximately
$263,091,000, which has been recorded as costs in excess of net assets of
businesses acquired attributable to such acquisitions in the accompanying Pro
Forma Combined Balance Sheet.     
   
  The Pro Forma Combined Balance Sheet has been adjusted to reflect the above
as follows:     
       
   
  (i) To record the assumed incurrence of $541,040,000 of indebtedness under
      the Committed Credit Facilities with an assumed effective interest rate
      of 7.50%. The incurrence of such additional indebtedness includes:
      (i) the cash consideration for the acquisition of WSMG of $369,600,000;
      (ii) the cash portion of the consideration for the acquisition of PED
      of $160,090,000; (iii) estimated transaction costs of $6,100,000; and
      (iv) estimated bank commitment fees of $5,250,000. The Company intends
      to retire a portion of such debt with the net proceeds of the Offerings
      and the Notes Offering or, if completion of the Common Stock Offerings
      and the Notes Offering occurs prior to the completion of the
      acquisitions of WSMG and PED, to use such proceeds directly to acquire
      WSMG and PED. See "Use of Proceeds."

       purchase prices and the estimated fair values of the identified net
       assets acquired. The adjustment is calculated as follows: (in

          reflect the goodwill amortization
          from the acquisitions of WSMG,
          PED, WaterPro and USG, with such

    (ii) To adjust interest expense related
          to the indebtedness of
          approximately $541,040,000 to be
          incurred to finance the
          acquisitions of WSMG and PED, net
          of historical interest expense
          recorded by WaterPro and PED on
          parent company debt. WaterPro and
          PED incurred interest on such
          parent company debt at the prime
          rate and approximately 11%,
          respectively, and incurred
          interest expense of $3,593,000
          and $19,865,000, respectively,
          for the fiscal year ended March
          31, 1996, and $2,433,000 and
          $9,469,000, respectively, for the
          six months ended September 30,
          1996, which interest expense has
          been eliminated because such debt
          would not have been in existence
          at the beginning of such periods.
          Interest on the indebtedness
          under the Committed Credit
          Facilities is assumed to be at an
          effective rate of 7.50% per
          annum. The Company, however,
          intends to retire a portion of
          such debt with the net proceeds
          of the Common Stock Offerings and
          the Notes Offering or, if
          completion of the Common Stock
          Offerings and the Notes Offering
          occurs prior to the completion of
          the acquisitions of WSMG and PED,
          to use such net proceeds directly
          to acquire WSMG and PED. See "Use
          of Proceeds."
          The assumed effective interest
          rate of 7.50% on the Committed
          Credit Facilities is subject to
          variability. A 0.125% increase/
          decrease in the assumed effective
          interest rate incrementally
          decreases/increases As Adjusted

c. During the fiscal year ended March 31, 1996 and the six months ended
   September 30, 1996, PED incurred significant restructuring charges relating
   to the plant closure and relocation of the operations of Wallace & Tiernan,
   Inc., a subsidiary, from Belleville, N.J., to Vineland, N.J. These
   restructuring charges totaled $9,260,000 and $1,992,000 for the fiscal year
   ended March 31, 1996 and the six months ended September 30, 1996,
   respectively. The Company believes that the restructuring and relocation
   will be completed prior to the acquisition of PED by the Company. The terms
   of the Stock Purchase Agreement between the Company and the United Utilities
   PLC provides that the Company will assume no ownership interest in and no
   liability associated with the Belleville, N.J. facility. Excluding the
   effects of these charges, net income and net income per common share for the
   fiscal year ended March 31, 1996 and the six months ended September 30, 1996

  The Selected Consolidated Financial Data as of and for the fiscal years
ended March 31, 1994, 1995 and 1996 are derived from the Consolidated
Financial Statements and Notes thereto of the Company, which are included
elsewhere herein. The financial data as of and for the six months ended
September 30, 1995 and 1996 are derived from unaudited consolidated financial
statements of the Company, which, in the opinion of the Company, reflect all
adjustments (consisting principally of normal, recurring accruals) necessary
for the fair statement of the financial position and results of operations for
the periods presented and are not necessarily indicative of the results for
any other interim period or for the full fiscal year. Historical consolidated
financial data for the fiscal years ended March 31, 1994, 1995 and 1996 and
the six months ended September 30, 1995 have been restated to reflect the
acquisitions in May 1996 and August 1996 of Zimpro and Davis, respectively,
which acquisitions have been accounted for as poolings of interests. The data
presented below are qualified in their entirety by and should be read in

(1) The historical consolidated financial data for the fiscal years ended
    March 31, 1994, 1995 and 1996 and for the six months ended September 30,
    1995 have been restated to include the accounts and operations of Zimpro
    and Davis, which were merged with the Company in May 1996 and August 1996,
    respectively, and accounted for as poolings of interests. The historical
    consolidated financial data for the six months ended September 30, 1996
    include the operations of Zimpro and have been restated to include the
    accounts and operations of Davis.     
   
(2) 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
    reflect four months of integration of Ionpure, certain charges totalling
    $2,359,000 related to the rationalization of certain wastewater operations
    and write-off of certain intangibles in the Company's Continental Penfield
    subsidiary totalling $3,738,000. In addition, the year ended March 31,
    1994 includes a charge of $8,895,000 to reflect a plan to shutdown and
    reorganize certain operations of Davis.     
(3) The fiscal year ended March 31, 1995 includes the results of operations of
    Smogless S.p.A., Crouzat S.A., Sation S.A., Seral Erich Alhauser GmbH and
    the Ceraflo ceramic product line from the dates of their respective
    acquisitions, accounted for as purchases. See Note 9 of Notes to
    Consolidated Financial Statements.
   
(4) The fiscal year ended March 31, 1996 includes the results of operations of
    The Permutit Company Limited and The Permutit Company Pty Ltd., Interlake
    Water Systems, ArrowHead Industrial Water, Inc. and Polymetrics, Inc. from
    the dates of their respective acquisitions, accounted for as purchases.
    See Note 9 of Notes to Consolidated Financial Statements.     
   
(5) Selling, general and administrative expenses for the year ended March 31,
    1996 includes charges totalling $3,193,000 related to the write-down of
    certain patents and equipment of Zimpro.     
(6) Net income (loss) per common share amounts are after dividends on the
    Series A Preferred Stock of $701,000 for the fiscal year ended March 31,
    1994, $715,000 for the fiscal year ended March 31, 1995 and $537,000 for
    the fiscal year ended March 31, 1996. The Series A Preferred Stock was
    converted into shares of Common Stock in March 1996.
   
(7) "EBITDA" consists of operating income plus depreciation and amortization.
    EBITDA data is presented because such data is used by certain investors to
    determine the Company's ability to meet debt service requirements. The
    Company considers EBITDA to be an indicative measure of the Company's
    operating performance. However, such information should not be considered
    as an alternative to net income, operating profit, cash flows from
    operations, or any other operating or liquidity performance measure
    prescribed by generally accepted accounting principles. The EBITDA measure
    presented by the Company may not be comparable to similarly titled
    measures by other companies.     
   
(8) The ratio of earnings to fixed charges has been computed by dividing
    earnings available for fixed charges (income before provision for income
    taxes, plus fixed charges) by fixed charges. Fixed charges consist of
    interest expense (including amortization of deferred financing costs) and
    the portion of rental expense that is representative of the interest
    factor (deemed by the Company to be one-third). Fixed charges exceeded
    earnings before fixed charges by $7,693,000 and $9,099,000 for the years
    ended March 31, 1992 and March 31, 1994, respectively. The ratio of
    earnings to fixed charges was 1.0x for the year ended March 31, 1993.     
   
(9)  The six months ended September 30, 1996 includes merger expenses of
     $5,581,000 related to the acquisition of Davis, which was accounted for
     as a pooling of interests.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion should be read in conjunction with the Company's
Consolidated Financial Statements and Notes thereto included elsewhere in this
Prospectus.
 
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 45 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 operations for current or future periods.
 
RESULTS OF OPERATIONS
   
  In May and August 1996, the Company merged with Zimpro and Davis,
respectively, in transactions accounted for as poolings of interests.
Historical consolidated financial data for the fiscal years ended March 31,
1994 through March 31, 1996 and the six months ended September 30, 1995 have
been restated to reflect the acquisitions in May 1996 and August 1996 of
Zimpro and Davis, respectively, which acquisitions have been accounted for as
poolings of interests. Historical financial data for the six months ended
September 30, 1996 have been restated to reflect the operations of Davis.     
 
  The following table sets forth for the periods indicated certain Selected
Consolidated Financial Data as a percentage of total revenues.

SIX MONTHS ENDED SEPTEMBER 30, 1996 COMPARED WITH SIX MONTHS ENDED SEPTEMBER
30, 1995     
 
 REVENUES
   
  Revenues for the six months ended September 30, 1996 were $433,719,000, an
increase of $101,620,000 from $332,099,000 for the comparable period of the
prior fiscal year. This 30.6% increase was due primarily to acquisitions
completed by the Company after September 30, 1995. For the six months ended
September 30, 1996, revenues from capital equipment sales represented 39% of
total revenues, while revenues from services and operations represented 22% of
total revenues, revenues from distribution represented 21% of total revenues
and revenues from replacement parts and consumables represented 18% of total
revenues.     
 
 GROSS PROFIT
   
  Gross profit increased 39.2% to $118,321,000 for the six months ended
September 30, 1996 from $85,006,000 for the comparable period of the prior
fiscal year. Total gross profit as a percentage of revenue ("gross margin")
increased to 27.3% for the six months ended September 30, 1996, compared to
25.6% for the comparable period of the prior fiscal year. The increase in
gross margin for the six months ended September 30, 1996 was due to: (i) a
continued strengthening of gross margin in the recurring and higher margin
service-based revenue business and (ii) rationalization of operations and
increased economies of scale from the integration of acquisitions.     
 
 SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
   
  For the six months ended September 30, 1996, selling, general and
administrative expenses, excluding merger expenses, increased $21,772,000 to
$86,140,000 as compared to the $64,368,000 in the comparable period in the
prior year. During this period, selling, general and administrative expenses,
excluding merger expenses, were 19.9% of revenues compared to 19.4% for the
comparable period in the prior year.This increase was primarily due to the
addition of sales and administrative personnel accompanying the Company's
recent acquisitions.     
   
  Excluding merger expenses, operating income as a percentage of revenues
increased to 7.4% for the six months ended September 30, 1996 from 6.2% for
the corresponding period in fiscal 1995 due primarily to improvement in gross
margin.     
   
 MERGER EXPENSES     
   
  Merger expenses were incurred during the six months ended September 30, 1996
relating to the Company's acquisition of Davis which was accounted for as a
pooling of interests. These merger expenses, which totaled $5,581,000,
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 $7,972,000 for the six months ended September
30, 1996 from $6,548,000 for the corresponding period in the prior year.
Interest expense for the six months ended September 30, 1996 consisted
primarily of interest on the Company's: (i) 5% Convertible Subordinated
Debentures due 2000 (all of which have been, as of October 25, 1996, converted
into shares of Common Stock); (ii) 6% Convertible Subordinated Notes issued on
September 18, 1995 due 2005; and (iii) borrowings under the Company's bank
line of credit. At September 30, 1996, the Company had cash and short-term
investments of $20,304,000.     
 
 INCOME TAX EXPENSE
   
  Income tax expense increased to $5,404,000 in the six months ended September
30, 1996, from $4,743,000 in the corresponding period in the prior year. The
Company's effective tax rate for the three and six months ended September 30,
1996 was 27.5% as compared to 30.7% in the corresponding period in the prior
year.

 REVENUES
 
  Revenues for fiscal 1996 were $727,903,000, an increase of $208,544,000 from
$519,359,000 for fiscal 1995. This 40.2% increase was due primarily to
acquisitions completed by the Company in fiscal 1995 and 1996. See Note 9 of
Notes to Consolidated Financial Statements related to acquisitions.
 
 GROSS PROFIT
 
  Gross profit increased 57.0% to $189,330,000 for fiscal 1996 from
$120,604,000 for fiscal 1995. Gross margin increased to 26.0% for fiscal 1996
as compared to 23.2% 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 $148,683,000 for
fiscal 1996 from $97,481,000 for fiscal 1995. This increase was primarily due
to the addition of sales and administrative personnel accompanying the
Company's recent acquisitions. As a percentage of revenues, selling, general
and administrative expenses were 20.4% for fiscal 1996, as compared to 18.8%
for fiscal 1995. This increase was due primarily to a write-down of certain
patents and equipment totalling $3,193,000 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 4.5% for fiscal 1995 to 5.6% for fiscal 1996 due primarily to
improvement in gross margin.
 
 INTEREST EXPENSE
 
  Interest expense increased to $14,419,000 for fiscal 1996 from $7,514,000
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 recent acquisitions.

 OTHER INCOME (EXPENSE)     
   
  Other income (expense) increased to $5,134,000 of income for fiscal 1996
from $1,442,000 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 $140,000,000 aggregate
principal amount of 6% Convertible Subordinated Notes on September 18, 1995
and the Company's issuance of 10,350,000 shares of Common Stock on May 3, 1995
with net proceeds of approximately $98,118,000.     
 
 INCOME TAX EXPENSE
 
  Income tax expense increased to $12,055,000 for fiscal 1996 from $4,812,000
for fiscal 1995. This increase was attributable to increased income. The
Company's effective tax rate for fiscal 1996 was 38.4% 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 $6,086,000 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 the
nondeductibility of certain items. As of March 31, 1996, the Company had net
operating loss carryforwards in France of approximately $19,952,000 and other
European countries of approximately $7,338,000 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 $14,362,000 for which financial statement benefit was recognized
in fiscal 1996. The Company also had net operating loss carryforwards
generated from Zimpro of approximately $2,905,000 for which financial
statement benefit has not been recognized. In addition, the benefit of the
French loss carryforwards must 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 $19,307,000 for fiscal 1996 from $12,239,000 for
fiscal 1995. Net income per common share increased to $0.45 per share (based
upon 42,159,000 weighted average common shares outstanding) for fiscal 1996
from $0.41 per common share (based upon 28,235,000 weighted average common
shares outstanding) for fiscal 1995, after deducting $536,000 and $715,000 for
dividends on the Company's preferred shares for fiscal 1996 and 1995,
respectively.

 REVENUES
 
  Revenues for fiscal 1995 were $519,359,000, an increase of $106,847,000 from
$412,512,000 for fiscal 1994. This 25.9% increase was due primarily to
acquisitions completed by the Company in fiscal 1994 and 1995. See Note 9 of
Notes to Consolidated Financial Statements related to acquisitions.
 
 GROSS PROFIT
 
  Gross profit increased 40.8% to $120,604,000 for fiscal 1995 from
$85,664,000 for fiscal 1994. Gross margin increased to 23.2% for fiscal 1995
as compared to 20.8% for fiscal 1994. The increase in gross margin through
fiscal 1995 was due to: (i) a continued strengthening of gross margin in the
recurring and higher margin service-based revenue business; and
(ii) rationalization of operations and economies of scale from the Company's
acquisitions. Gross margin in the Company's distribution business remained
unchanged in fiscal 1995 as compared to fiscal 1994.
 
 SELLING, GENERAL AND ADMINISTRATIVE EXPENSES
 
  Selling, general and administrative expenses increased to $97,481,000 for
fiscal 1995 from $90,719,000 for fiscal 1994. This increase was primarily due
to the addition of sales and administrative personnel accompanying the
Company's recent acquisitions. As a percentage of revenues, selling, general
and administrative expenses
 
                                      34
<PAGE>
 
   
were 18.8% during fiscal 1995, as compared to 22.0% for fiscal 1994. This
decrease in selling, general and administrative expenses as a percentage of
revenues for fiscal 1995 as compared to fiscal 1994 was due primarily to (i)
the Company's emphasis on cost reductions and administrative efficiencies
gained through economies of scale, (ii) the write-off of certain intangibles
in the Company's Continental Penfield subsidiary totalling $3,738,000 in
fiscal 1994, (iii) the exclusion from operating results in fiscal 1995 of a
division of Davis which was shut down in fiscal 1994, and (iv) certain charges
totalling $2,359,000 related to the rationalization of certain wastewater
operations. See Note 8 of Notes to Consolidated Financial Statements related
to such shutdown.     
 
  Due primarily to the decrease in selling, general and administrative
expenses as a percentage of revenues and the improvement in gross margin,
operating income as a percentage of revenues increased from a loss of 1.2% for
fiscal 1994 to 4.5% for fiscal 1995.
 
 INTEREST EXPENSE
 
  Interest expense increased to $7,514,000 for fiscal 1995 from $4,044,000 for
fiscal 1994. Interest expense for fiscal 1995 consisted primarily of interest
on the Company's 5% Convertible Subordinated Debentures due 2000 issued
October 20, 1993 and interest on increased borrowings under the Company's bank
line of credit, which was used to finance the Company's revenue expansion and
recent acquisitions.
   
 OTHER INCOME (EXPENSE)     
   
  Other income (expense) increased $8,824,000 in fiscal 1995 from an expense
of $7,382,000 in fiscal 1994 to income of $1,442,000 in fiscal 1995. During
the fourth quarter of fiscal 1994, the Company's Davis subsidiary adopted a
plan to shutdown or reorganize the operations of its wholly owned subsidiary,
The Taulman Company ("Taulman"). The pre-tax loss provision for these actions
was recorded in fiscal 1994 and included the write-off of intangible assets
totaling $2,908,000 associated with Taulman and the accrual of $5,987,000 to
provide for anticipated losses during the shutdown.     
 
 INCOME TAX EXPENSE
 
  Income tax expense increased to $4,812,000 for fiscal 1995 from a tax
benefit of $7,087,000 for fiscal 1994. This increase was attributable to
increased income and the Company's partial recognition during fiscal 1994 of
the future income tax benefit related to federal net operating loss
carryforwards. As of March 31, 1995, the Company had net operating loss
carryforwards in France of approximately $20,351,000 and other European
countries of approximately $6,400,000 for which no financial statement benefit
had been recognized. In addition, the Company had net operating loss
carryforwards generated from its Liquipure subsidiary of approximately
$13,500,000 for which no financial statement benefit was recognized. Future
recognition of these carryforwards will be reflected if the above operations
generate sufficient earnings before the expiration periods of the loss
carryforwards. In addition, the benefit of the French loss carryforwards must
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 $12,239,000 for fiscal 1995 from a net loss of
$9,394,000 for fiscal 1994. Net income per common share increased to $0.41 per
share (based upon 28,235,000 weighted average common shares outstanding) for
fiscal 1995 from a net loss of $0.42 per common share (based upon 23,934,000
weighted average common shares outstanding) for fiscal 1994, after deducting
$715,000 and $701,000 for dividends on the Company's preferred shares for
fiscal 1995 and 1994, respectively.

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 bank
line of credit. At September 30, 1996, the Company had working capital of
$168,606,000, including cash and short-term investments of $20,304,000. The
Company's long-term debt at September 30, 1996 included $53,565,000 aggregate
principal amount of 5% Convertible Subordinated Debentures due 2000 (all of
which were converted into 4,390,000 shares of Common Stock on October 25,
1996), $140,000,000 of 6% Convertible Subordinated Notes due 2005 and other
long-term debt totalling $9,003,000 and bearing interest at rates ranging from
2.0% to 11.5%.     
   
  Capital expenditures totaled $8,050,000, $18,304,000 and $28,392,000 for
fiscal years ended March 31, 1994, 1995, and 1996, 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 acquisitions of USG and WaterPro and
the pending acquisitions of WSMG and PED. The Company has no plans for further
investments in leasehold interests.     
   
  As of September 30, 1996, the Company had an existing multicurrency bank
line of credit of $135,000,000, of which there were outstanding borrowings of
$81,156,000 and outstanding letters of credit of $14,446,000. The Company
expects to obtain all or part of the funds necessary to complete the WSMG
acquisition and the PED acquisition from borrowings under bank credit
facilities. The Company has received a commitment letter from The First
National Bank of Boston pursuant to which, subject to the satisfaction of
various conditions, credit facilities of up to $700,000,000 would be made
available to the Company to finance acquisitions (including the WSMG
acquisition and the PED acquisition), to refinance any borrowings under the
Company's current credit agreement, and for working capital and other general
corporate purposes. The existing bank line of credit is, and the anticipated
credit facilities would be, secured by the stock of certain of the Company's
United States subsidiaries. Borrowings under these committed credit facilities
would bear interest at variable rates of up to 2.25% above certain
Eurocurrency rates or 0.50% above The First National Bank of Boston's base
rate and have a five year maturity. The Company anticipates that, following
completion of the Notes Offering and/or the Common Stock Offerings, the
Company's facilities will be reduced to a level that the Company considers
appropriate for its working capital and other needs.     
 
  As of March 31, 1996, the Company had net operating loss carryforwards
generated from Societe des Ceramiques Techniques S.A. ("SCT") of approximately
$19,952,000, for which no financial statement benefit has been recognized.
Approximately $1,946,000 of net operating loss carryforwards will expire in
fiscal years 1997 and 1998, while the remainder have an indefinite
carryforward period. The Company also has net operating loss carryforwards in
other European countries of approximately $7,338,000 which expire from fiscal
1997 to 2002 for which no financial statement benefit has been recognized. The
Company also has net operating loss carryforwards generated from Zimpro of
approximately $2,905,000 for which no financial statement benefit has been
recognized. No benefit has been given to these net operating loss carryfowards
because of the limited carryforward periods or the uncertain business
conditions relating to the operations giving rise to such carryforwards.
Future recognition of these net operating carryforwards will occur if the
operations of SCT and Zimpro generate sufficient earnings before the
expiration of the respective net operating loss carryforwards. In addition, in
the case of SCT, until March 31, 1997, the benefit, if any, of such
carryforwards is to be shared equally between the Company and Aluminum Company
of America.
 
  The Company also has available at March 31, 1996, other net operating loss
carryforwards for Federal income tax purposes of approximately $13,552,000
which expire from fiscal 2007 to 2010.
   
  Pursuant to an agreement entered into in conjunction with the acquisition of
WaterPro, all former WaterPro stockholders and former WaterPro debtholders,
who together hold an aggregate of 3,201,507 shares of the Common Stock, have
the right, exercisable during the 90-day period commencing on December 27,
1996, to require the Company to purchase all or any portion of such shares of
Common Stock at a purchase price equal to $33.24 per share.     
 
                                      36
<PAGE>
 
   
  Pursuant to an agreement to be entered into in conjunction with the pending
acquisition of PED, the Company has agreed to pay in cash the portion of the
purchase price otherwise payable in shares of Common Stock if such shares are
not at the time of issuance immediately saleable pursuant to the Company's
shelf Registration Statement on Form S-4. In addition, the Agreement provides
that if such shares are issued and any or all of them are sold within a
specified number of days after consummation of the acquisition for net
proceeds per share of less than an amount determined by dividing
(Pounds)25,000,000 by the number of shares issued, the Company will pay the
aggregate deficiency to PED in cash, and if the net proceeds per share exceed
such amount, PED will pay the aggregate excess to the Company in cash.     
 
  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 for working capital, revenue growth,
scheduled debt repayment and capital investment objectives for at least the
next twelve months.

                         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 water ("influent"). Public
water departments, 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 ("effluent"). Growing demand for treated water
combined with the limited supply of usable water has created a significant
need for cost-effective, sophisticated water and wastewater treatment
solutions. Water and wastewater treatment has developed into a multi-billion
dollar global industry.
 
  The global water and wastewater treatment industry is highly fragmented,
with numerous regional participants 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 government 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 thousands 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.
 
  Customers of the water and wastewater treatment industry can be classified
into three broad categories: (i) industrial businesses, which include
companies in such markets as power generation, chemical process, oil,
pharmaceutical, microelectronics, automotive and steel; (ii) municipal and
private suppliers of public water and wastewater services; and (iii)
individual consumers of bottled water and household point-of-use products,
such as domestic filtration systems and parts.
 
INDUSTRIAL USERS
 
  Industrial users have a significant need for treated water because it is a
necessary component in many products and industrial processes. The quality of
water varies dramatically across geographic regions, and water contains
impurities that, if untreated, can render it effectively useless for most
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 influent 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 influent.
 
  In addition to treating their influent to ensure product quality, industrial
users are often required to treat their effluent. 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 effluent. As a result of
these factors, industrial companies increasingly require complex systems and
equipment to treat and recycle process water and wastewater.
 
  Industrialization worldwide, manufacturers' desire to enhance productivity,
rising water prices, increased regulation and emphasis on water recycling and
reuse affect demand for industrial water and wastewater treatment and have
resulted in the need for increasingly sophisticated industrial water and
wastewater treatment
 
                                      38
<PAGE>
 
systems. Rather than committing the significant resources required to operate
complex in-house systems, industrial customers are increasingly outsourcing
their water and wastewater treatment needs to water and wastewater treatment
companies to build, own and/or operate the customer's facilities or to provide
treated water under contract.
 
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 wastewater.
As a result, municipalities are experiencing increasing costs for water and
wastewater treatment.
 
  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.
 
INDIVIDUAL USERS
 
  The market for individual users consists of bottled water and point-of-use
products, such as residential filtration systems and parts. 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.

customers with ongoing local service and maintenance. The Company is also a
leading provider of SDI and outsourced water services, including the operation
of water and wastewater treatment systems at customer sites.
   
  The Company has grown internally and through the strategic acquisition and
successful integration of more than 45 domestic and international water and
wastewater treatment companies since 1991. On a previously reported basis, the
Company's revenues have grown to $472.5 million for the fiscal year ended
March 31, 1996 from $41.2 million for the fiscal year ended March 31, 1992,
representing a compound annual growth rate of approximately 84%. The Company's
revenues for the fiscal year ended March 31, 1996 would have been
approximately $1.8 billion after giving effect to the acquisitions of Zimpro
and Davis (accounted for as poolings of interests) and including, on a pro
forma basis, the pending acquisitions of WSMG and PED and the recent
acquisitions of WaterPro and USG as if such acquisitions were completed at the
beginning of such year.     
 
  Global population growth, economic expansion, scarcity of available water
resources, heightened public concern about water quality and growing
regulatory requirements have resulted in: (i) continued growth of the
multibillion dollar water and wastewater treatment industry; and (ii)
heightened demand for increasingly complex water and wastewater treatment
systems. The water and wastewater treatment industry is highly fragmented,
with numerous regional participants who provide customers with a limited range
of water and wastewater treatment solutions. The Company differentiates itself
from competitors by serving as a single-source water and wastewater treatment
provider capable of designing, manufacturing, operating, financing and
maintaining water and wastewater systems on a local basis for industrial and
municipal customers. The Company's customer base includes a broad range of
major industrial customers, which require treated water as a necessary
component of many products and industrial processes, and municipalities, which
treat water and wastewater for their communities. Industrial customers include
Chinese Petroleum, Coca-Cola, Dow Chemical, General Motors, Hyundai, Intel,
Johnson & Johnson, Merck, Procter & Gamble, and Samsung. Municipal customers
include the Cities of Los Angeles, Minneapolis-St. Paul, and St. Louis.
 
STRATEGY
 
  In order to achieve earnings growth and expand its operations to enhance its
position as a leading global single-source provider of water and wastewater
treatment systems and services, the Company has developed the following
strategy:
 
  PROVIDE SINGLE-SOURCE WATER AND WASTEWATER TREATMENT SOLUTIONS TO
  INDUSTRIAL AND MUNICIPAL CUSTOMERS. The Company believes that industrial
  and municipal users of water and wastewater treatment systems, products and
  services increasingly desire to obtain from a single source a broad range
  of systems, technologies and services. The Company addresses the full scope
  of its customers' water and wastewater treatment needs through what the
  Company believes is the industry's broadest line of cost-effective
  treatment systems, services and proven technologies. In addition, the
  Company has an extensive global distribution network through which it
  offers customers convenient local service and support. The Company also
  meets the diverse demands of its customers through its ability to sell
  systems outright, to sell systems and operate them for its customers, or to
  build, own, operate and finance such systems.
 
  PURSUE ACQUISITIONS THAT PROVIDE A STRATEGIC FIT AND CONTRIBUTE TO REVENUE
  AND EARNINGS GROWTH. In addition to growing internally, the Company has
  grown significantly since 1991 through the strategic
 
                                      40
<PAGE>
 
  acquisition of more than 45 United States-based and international
  businesses with strong market positions and substantial water and
  wastewater treatment expertise. These acquisitions have enabled the Company
  to expand its geographic presence, industries served, installed base, range
  of products and technologies offered and network of sales and distribution
  facilities. 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.
     
  REALIZE SYNERGIES AND ECONOMIES OF SCALE FROM ACQUISITIONS. The Company
  operates its business through an organizational structure which provides
  low overhead, minimizes redundancy and creates opportunities to achieve
  cost savings and synergies in its acquisitions. The Company has significant
  experience in integrating acquired businesses. The Company believes that
  the acquisitions of Davis, WaterPro and USG and the pending acquisitions of
  WSMG and PED will provide cost savings through rationalization of
  operations and economies of scale, including increased asset utilization.
  The Company also believes that the integration of these recent and pending
  acquisitions will provide synergies, such as cross-selling of product lines
  to a broader customer base, expanded distribution and service capabilities
  and exchange of experience and technology.     
 
  EXPAND GLOBAL MARKET PRESENCE, ESPECIALLY IN THE PACIFIC RIM REGION. The
  Company expects that population growth, economic expansion and continued
  degradation of water quality in both industrialized and less-developed
  countries will result in strong growth in international markets. The
  Company intends to further increase its international market presence by
  expanding its international operations and by acquiring additional
  international businesses. The Company believes that the proposed
  acquisitions of WSMG and PED will significantly strengthen the Company's
  capabilities in the Pacific Rim and Europe.
     
  EXPAND PENETRATION OF THE MUNICIPAL MARKET. The Company believes that the
  recent acquisitions of Davis, WaterPro and USG and the pending acquisitions
  of WSMG and PED will significantly expand its presence in the municipal
  market. The Company intends to strengthen its municipal presence by
  utilizing WSMG's and PED's strong technologies, product offerings and
  reputation in the municipal market to capitalize on cross-selling
  opportunities and improve its municipal sales channels. Additionally, the
  Company intends to use its extensive distribution network, including the
  long-term municipal relationships and local service capabilities of Davis,
  WaterPro and USG, as a channel to expand its penetration of the municipal
  market. The Company believes that its combination of single-source provider
  capabilities, local service capabilities and long-term municipal
  relationships will provide a significant competitive advantage in
  penetrating the municipal market.     
     
  CAPITALIZE ON DISTRIBUTION STRENGTH TO ENHANCE LOCAL SALES AND SERVICE
  CAPABILITIES. The Company believes that the acquisitions of Davis, WaterPro
  and USG establish the Company as a leading distributor of water and
  wastewater distribution products and services to both the industrial and
  municipal markets. These acquisitions are expected to provide the Company
  with a platform to: (i) enhance the Company's local sales and service
  infrastructure; (ii) penetrate the municipal segment of the water and
  wastewater treatment market by capitalizing on each distribution company's
  long-term municipal relationships; (iii) leverage the Company's leading
  manufacturing capabilities and technology base; and (iv) capitalize upon
  efficiencies from consolidation of operations and economies of scale. In
  addition, the Company believes that these distribution acquisitions will
  allow the Company to capitalize on opportunities to retrofit, replace and
  repair aging water infrastructure in the United States.     
     
  CAPITALIZE ON OUTSOURCING AND PRIVATIZATION OPPORTUNITIES. The Company is
  currently a 50% owner of TWO, which focuses on the outsourcing of
  industrial customers' water treatment needs. The operating strategy for
  TWO, or, if formed, the Joint Venture, is or would be to offer customers:
  (i) turnkey operation, including system design, manufacture, operation, and
  maintenance on a local basis; (ii) warrantied performance; (iii) potential
  cost savings; and (iv) customized financing options.

PRINCIPAL PRODUCTS AND SERVICES
 
  The Company's principal products and services can be divided into the
following four groups: capital equipment, services, replacement parts and
consumables, and distribution.
 
  CAPITAL EQUIPMENT. The Company manufactures both standard and customized
water and wastewater treatment equipment. The Company believes that its
systems utilize the industry's broadest range of proven physical, biological
and chemical treatment technologies including, among others, continuous
deionization, reverse osmosis, electrodialysis, adsorption and ion exchange,
that can be combined and configured to meet wide-ranging customer needs. The
Company designs, engineers, manufactures and assembles its systems at its
manufacturing facilities located in the United States and internationally.
Components that are not manufactured by the Company are purchased from vendors
in the United States and internationally. The Company utilizes its
distribution network including its global sales and service force, as well as
manufacturers' representatives, to provide direct contact and service to its
customers.
 
  SERVICES. The Company's service business consists of the following: SDI,
outsourcing of water and wastewater treatment under long-term contracts,
mobile water treatment and, following the pending acquisition of WSMG, carbon
regeneration. SDI is a term given to portable water deionization treatment
equipment that uses ion exchange resins as a filtration medium and is designed
to connect easily to a local water supply. Resin is retrieved and transported
by a Company service representative to a Company regeneration plant for
chemical recharging when it is exhausted. Service-based revenues have been
generally recurring in nature, and have historically generated higher profit
margins than capital equipment sales.
   
  TWO, which is 50% owned by a subsidiary of Nalco Chemical Company ("Nalco")
and 50% owned by a subsidiary of the Company, was formed to finance, build,
own and operate water treatment systems at customer sites under long-term
contracts and to focus on the outsourcing of industrial customers' water
treatment needs. The Company and Nalco have entered into long-term supply and
service agreements with TWO in order to support TWO's performance under such
contracts.     
 
  REPLACEMENT PARTS AND CONSUMABLES. The Company manufactures and sells
replacement parts and consumables, such as membranes, ion exchange resin and
carbon, manufactured by both the Company and other suppliers that are required
to support water treatment systems.
   
  DISTRIBUTION. The Company believes that the acquisitions of Davis, of
WaterPro and USG establish the Company as a leading distributor of water and
wastewater distribution products and services. The Company emphasizes
convenient customer support, with each distribution office servicing customers
within approximately a 50 mile to 150 mile radius, depending on population
density in the area.     
 
CUSTOMER MARKETS AND PRODUCT APPLICATIONS
 
  The markets for the Company's services and products span many industries and
many geographic locations, including the United States, Europe, Pacific Rim
and Latin America. Information regarding the amount of revenue, operating
income and assets attributable to United States and international sales for
each of the past three fiscal years appears in Note 17 of Notes to
Consolidated Financial Statements, included elsewhere herein. The following
are industries that the Company serves and some of the products used therein:
 
  PHARMACEUTICAL AND BIOTECHNOLOGY. Process water used in the pharmaceutical
  and biotechnology industries must meet the highest standards of purity.
  Reverse osmosis in conjunction with CDI ("RO/CDI") technology provides
  high-purity water that meets the strictest quality specifications. The
  Company's ceramic membranes, in combination with other membrane or ion
  exchange equipment, meet these requirements by achieving nearly 100%
  contaminant removal. This equipment is used in fermentation, purification
  and recovery processes. Ion exchange technologies are also used to purify
  process streams, as well as to purify and recover antibiotics, vitamins and
  chemical elements. In addition, ion exchange is employed in industrial
  fermentation to process substrates.
 
                                      42
<PAGE>
 
  MICROELECTRONICS. Microelectronics manufacturing processes require ultra-
  high purity water to avoid contamination from even the smallest microscopic
  particles. The Company's ceramic membrane filters are advanced inorganic,
  multilayered filter media that provide superior contaminant removal in the
  most demanding environments. In addition, the Company's membrane and ion
  exchange technology is used by electronic components manufacturers to
  produce ultra-high purity water and to reduce the level of
  microcontamination in rinse waters.
 
  AUTOMOTIVE. The Company designs, manufactures, sells, services and
  operates, on a global basis, a broad portfolio of technologies for the
  automotive industry. The specific manufacturing processes include metal
  processing, metal finishing, assembly and non-metal processing. Each of
  these processes operates under the strictest of quality, process control
  and regulatory requirements. The Company offers all of the technologies
  necessary to meet these requirements including physical, chemical and
  biological methods. The Company can deliver these technologies as bid-to-
  specification equipment, full turnkey, service, build-own-operate or any
  combination of the above. Of particular importance are the Company's
  capabilities in the areas of water reuse and resource recovery.
 
  CHEMICAL AND PETROCHEMICAL. Incoming water supplies for chemical and
  petrochemical manufacturers require filtration and treatment to remove
  solid particles and dissolved impurities. The Company manufactures
  demineralizers, water softeners, clarifiers, multimedia filters and reverse
  osmosis systems to deliver water of controlled quality and content.
  Additionally, the Company's Membralox(R) and Ceraflo ceramic membranes are
  used to accomplish the separation of chemical and petrochemical streams in
  very harsh environments.
 
  FOOD AND BEVERAGE. The food and beverage industries require high-quality
  yet cost-effective water treatment systems. The Company offers physical and
  chemical filtration and treatment technologies to purify incoming water and
  refine and concentrate process fluids. Its ion exchange and ADSEP systems
  are advanced technologies for the separation of sugars and corn syrups. In
  the beverage industry, ceramic membrane filters achieve a high level of
  fluid purity using nonchemical processing techniques.
 
  METAL FINISHING. The Company's metal treatment and recovery systems
  facilitate regulatory compliance of effluent and reduce the level of heavy
  metals and solids generated from metal finishing operations such as printed
  circuit board manufacturing, electroplating, galvanizing and anodizing. The
  Company's key technology offerings include ion exchange, reverse osmosis,
  electrolytic recovery, adsorption filtration, ceramic membrane
  ultrafiltration, as well as a full complement of conventional precipitation
  settling and filtration technologies.
 
  POWER GENERATION. Nuclear and fossil-fueled electric power plants are
  subject to steam generator and boiler corrosion and turbine fouling if
  damaging contaminants are not removed from the incoming and recirculating
  feedwater supplies. The Company's filtration membrane and ion exchange
  systems provide power plants with high-quality, demineralized boiler
  feedwater. The Company's tube filter and deep bed condensate polishing
  systems employ advanced resin separation and regeneration technologies to
  improve the quality of the condensate returned to the boiler. Sand and
  other media filters are used in cogeneration and other power plant
  applications. Nuclear-grade resins are available to meet the more stringent
  water quality requirements of nuclear power plants.
 
  OIL FIELD AND REFINERY. The petroleum industry uses large quantities of
  water for steam and water flooding of oil fields for the secondary recovery
  of oil. The Company's systems remove oil contaminants and suspended solids
  from the resurfaced water for reuse for down-hole water and steam
  injection. Refineries use the Company's oil/water separators to remove oil
  and suspended solids from process water and refinery effluents, as well as
  a full range of water purification equipment to remove dissolved solids.
 
  MEDICAL/DIALYSIS. RO/CDI systems produce a continuous stream of ultra-high
  purity water by removing organics, minerals and other contaminants while
  providing the necessary bacteria and endotoxin control for high-flux
  dialysis machines and other high-quality, high-capacity water requirements
  in the medical field.
 
                                      43
<PAGE>
 
  LABORATORY/RESEARCH AND DEVELOPMENT/QUALITY CONTROL/CHEMICAL
  ANALYSIS. Cartridge-type reverse osmosis filters, deionization systems,
  electrodialysis modules, ultrafiltration units, particle filters and
  activated carbon filters remove contaminants, bacteria, pyrogens and odor
  to provide point-of-use water polishing for critical and demanding
  laboratory applications.
 
  PULP AND PAPER. The Company's dissolved air flotation systems remove and
  recover suspended solids from waste streams for pulp and paper
  manufacturers and require considerably less floor space than conventional
  separation units. The Company's boiler feedwater treatment systems are also
  utilized in this industry.
 
  GROUNDWATER REMEDIATION AND LANDFILL LEACHATE TREATMENT. The Company's
  remediation systems are used to remove organic compounds and soluble metals
  from contaminated groundwater. Biosystems employ a "pump and treat"
  technology that incorporates equalization, separation of metals, biological
  treatment and clarification processes. The Company's leachate systems,
  combining chemical pre-treatment systems with biological treatment
  technologies, address the treatment or elimination of wastewater drainage
  into the groundwater and surrounding waterways.
 
  POTABLE WATER. Hotels and other institutions require high-quality yet
  affordable water treatment systems to meet consumer and regulatory
  standards. In addition, suppliers of drinking water are seeking alternative
  purification systems. The Company manufactures filtration, water treatment
  and clarification systems for the drinking water industry that meet United
  States Environmental Protection Agency ("EPA") standards under the Safe
  Drinking Water Act. Pre-assembled systems capable of handling low- and
  high-volume flows are also available.
 
  MUNICIPAL WASTEWATER TREATMENT, RECOVERY AND REUSE. Municipal sewage plants
  often utilize three stages of treatment (primary, secondary and tertiary)
  before discharge to the environment. In addition to offering equipment and
  systems to satisfy these requirements, the Company's membrane, reverse
  osmosis and ion exchange technologies add a fourth stage by removing
  remaining contaminants to a purity level that allows water to be recycled
  and reused in additional industrial applications. These technologies are
  cost-effective and reduce the adverse impact of industrial growth in
  communities where water tables are low.
 
BACKLOG
   
  The Company had the following backlog as of September 30, 1995 and 1996,
which includes capital equipment purchase orders and revenues expected to be
generated during the succeeding 12 months under certain long-term contracts.
The capital equipment orders are scheduled for delivery and installation
during the succeeding 12 months and are believed by the Company to be firm.

                           DESCRIPTION OF THE NOTES
 
  Set forth below is a summary of certain provisions of the Notes. The Notes
will be issued pursuant to an indenture (the "Indenture") to be dated as of
   , 1996, by and between the Company and State Street Bank and Trust Company
of California, N.A., as trustee (the "Trustee"), a copy of which is filed as
an exhibit to the Registration Statement of which this Prospectus is a part.
The terms of the Indenture are also governed by certain provisions contained
in the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").
The following summary of the Notes and the Indenture does not purport to be
complete and is subject to, and is qualified in its entirety by, reference to
all of the provisions of the Indenture, including the definitions therein of
certain terms which are not otherwise defined in this Prospectus and those
terms made a part of the Indenture by reference to the Trust Indenture Act as
in effect on the date of the Indenture. Capitalized terms used herein without
definition have the meanings ascribed to them in the Indenture. As used in
this section "Description of the Notes," the "Company" refers to United States
Filter Corporation, exclusive of its subsidiaries. Wherever particular
provisions of the Indenture are referred to in this summary, such provisions
are incorporated by reference as a part of the statements made and such
statements are qualified in their entirety by such reference.
 
GENERAL
   
  The Notes will be unsecured, subordinated, general obligations of the
Company, limited in aggregate principal amount to $200,000,000 ($230,000,000
if the Underwriters' over-allotment option is exercised in full). The Notes
will be subordinated in right of payment to all Senior Indebtedness of the
Company, as described under "Subordination" below. The Notes will be issued
only in fully registered form, without coupons, in denominations of $1,000 and
integral multiples thereof.     
 
  The Notes will mature on    , 2001. The Notes will bear interest at the rate
per annum stated on the cover page of this Prospectus from the date of
issuance or from the most recent Interest Payment Date to which interest has
been paid or provided for, payable semiannually on    and    of each year,
commencing    , 1997 to the persons in whose names such Notes are registered
at the close of business on    or    immediately preceding such Interest
Payment Date. Principal of, premium, if any, and interest on, the Notes will
be payable, the Notes will be convertible and the Notes may be presented for
registration of transfer or exchange, at the office or agency of the Company
maintained for such purpose, which office or agency shall be maintained in the
Borough of Manhattan, The City of New York. Interest will be calculated on the
basis of a 360-day year consisting of twelve 30-day months.
 
  At the option of the Company, payment of interest may be made by check
mailed to the Holders of the Notes at the addresses set forth upon the
registry books of the Registrar. No service charge will be made for any
registration of transfer or exchange of Notes, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. Until otherwise designated by the Company,
the Company's office or agency will be the corporate trust office of the
Trustee presently located at 725 South Figueroa Street, Suite 3100, Los
Angeles, California 90017.
 
CONVERSION RIGHTS
 
  The Holder of any Notes will have the right, at the Holder's option, to
convert any portion of the principal amount thereof that is an integral
multiple of $1,000 into shares of Common Stock, at any time prior to the close
of business on the second Business Day prior to the Stated Maturity of the
Notes (unless earlier redeemed or repurchased) at the Conversion Price set
forth on the cover page of this Prospectus (subject to adjustment as described
below). The right to convert a Note called for redemption or delivered for
repurchase will terminate at the close of business on the Business Day prior
to the Redemption Date or Repurchase Date for such Note, unless the Company
subsequently fails to pay the applicable Redemption Price or Repurchase Price,
as the case may be.
 
  In the case of any Note that has been converted after any Record Date, but
on or before the next Interest Payment Date, interest the stated due date of
which is on such Interest Payment Date shall be payable on such Interest
Payment Date notwithstanding such conversion, and such interest shall be paid
to the Holder of such
 
                                      50
<PAGE>
 
Note who is a Holder on such Record Date. Any Note so converted must be
accompanied by payment to the Company of an amount equal to the interest
payable on such Interest Payment Date on the principal amount of Notes being
surrendered for conversion (unless such Note shall have been called for
redemption, in which case no such payment shall be required). In all cases,
Holders as of the Record Date immediately preceding       , 1999 will receive
the interest payment due on       , 1999, even if such Holder surrenders a
Note for conversion after such Record Date as a result of the Company's
exercise of its right to redeem the Notes on or after       , 1999. No
fractional shares will be issued upon conversion but, in lieu thereof, an
appropriate amount will be paid in cash by the Company based on the market
price of Common Stock (as determined in accordance with the Indenture) at the
close of business on the Date of Conversion.
 
  The Conversion Price will be subject to adjustment upon the occurrence of
certain events, including: (a) any payment of a dividend (or other
distribution) payable in Common Stock on any class of Capital Stock of the
Company, (b) any issuance to all holders of Common Stock of rights, options or
warrants entitling them to subscribe for or purchase Common Stock at less than
the then current market price (as determined in accordance with the Indenture)
of Common Stock; provided, however, that if such options or warrants are only
exercisable upon the occurrence of certain triggering events, then the
Conversion Price will not be adjusted until such triggering events occur, (c)
any subdivision, combination or reclassification of Common Stock, (d) any
distribution to all holders of Common Stock of evidences of indebtedness,
shares of Capital Stock other than Common Stock, cash or other assets
(including securities, but excluding those dividends, rights, options,
warrants and distributions referred to above and excluding regular dividends
and distributions paid exclusively in cash), (e) any distribution consisting
exclusively of cash (excluding any cash portion of distributions referred to
in (d) above, or cash distributed upon a merger or consolidation to which the
second succeeding paragraph applies) to all holders of Common Stock in an
aggregate amount that, combined together with (i) all other such all-cash
distributions made within the then preceding 12 months in respect of which no
adjustment has been made and (ii) any cash and the fair market value of other
consideration paid or payable in respect of any tender offer by the Company or
any of its Subsidiaries for Common Stock concluded within the preceding 12
months in respect of which no adjustment has been made, exceeds 15% of the
Company's market capitalization (defined as being the product of the then
current market price of the Common Stock times the number of shares of Common
Stock then outstanding) on the record date of such distribution, and (f) the
completion of a tender or exchange offer made by the Company or any of its
Subsidiaries for Common Stock that involves an aggregate consideration that,
together with (i) any cash and other consideration payable in a tender or
exchange offer by the Company or any of its Subsidiaries for Common Stock
expiring within the 12 months preceding the expiration of such tender or
exchange offer in respect of which no adjustment has been made and (ii) the
aggregate amount of any such all-cash distributions referred to in (e) above
to all holders of Common Stock within the 12 months preceding the expiration
of such tender or exchange offer in respect of which no adjustments have been
made, exceeds 15% of the Company's market capitalization on the expiration of
such tender offer. No adjustment of the Conversion Price will be required to
be made until the cumulative adjustments amount to 1.0% or more of the
Conversion Price as last adjusted. The Company reserves the right to make such
reductions in the Conversion Price in addition to those required in the
foregoing provisions as it considers to be advisable in order that any event
treated for federal income tax purposes as a dividend of stock or stock rights
will not be taxable to the recipients. In the event the Company elects to make
such a reduction in the conversion price, the Company will comply with the
requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and any other securities laws and regulations
thereunder if and to the extent that such laws and regulations are applicable
in connection with the reduction of the Conversion Price.
 
  In the event that the Company distributes rights or warrants (other than
those referred to in (b) in the preceding paragraph) pro rata to holders of
Common Stock, so long as any such rights or warrants have not expired or been
redeemed by the Company, the Holder of any Note surrendered for conversion
will be entitled to receive upon such conversion, in addition to the shares of
Common Stock issuable upon such conversion (the "Conversion Shares"), a number
of rights or warrants to be determined as follows: (i) if such conversion
occurs on or prior to the date for the distribution to the holders of rights
or warrants of separate certificates evidencing such rights or warrants (the
"Distribution Date"), the same number of rights or warrants to which a holder
of a
 
                                      51
<PAGE>
 
number of shares of Common Stock equal to the number of Conversion Shares is
entitled at the time of such conversion in accordance with the terms and
provisions of and applicable to the rights or warrants, and (ii) if such
conversion occurs after such Distribution Date, the same number of rights or
warrants to which a holder of the number of shares of Common Stock into which
such Note was convertible immediately prior to such Distribution Date would
have been entitled on such Distribution Date in accordance with the terms and
provisions of and applicable to the rights or warrants. The conversion price
of the Notes will not be subject to adjustment on account of any declaration,
distribution or exercise of such rights or warrants.
 
  In case of any reclassification, consolidation or merger of the Company with
or into another person or any merger of another person with or into the
Company (with certain exceptions), or in case of any sale, transfer or
conveyance of all or substantially all of the assets of the Company (computed
on a consolidated basis), each Note then outstanding will, without the consent
of any Holder of Notes, become convertible only into the kind and amount of
securities, cash and other property receivable upon such reclassification,
consolidation, merger, sale, transfer or conveyance by a holder of the number
of shares of Common Stock into which such Note was convertible immediately
prior thereto, after giving effect to any adjustment event, who failed to
exercise any rights of election and received per share the kind and amount
received per share by a plurality of non-electing shares.
 
SUBORDINATION
   
  The Notes will be general, unsecured obligations of the Company,
subordinated in right of payment to all existing and future Senior
Indebtedness of the Company. At September 30, 1996, as adjusted to give effect
to the issuance and sale of the Notes and the application of the net proceeds
therefrom, the Company would have had approximately $137.9 million of Senior
Indebtedness outstanding. The Notes are subordinated by operation of law in
right of payment to all liabilities (including trade payables) of the
Company's Subsidiaries. The Company's Subsidiaries had approximately $473.0
million of trade payables and accrued liabilities outstanding at September 30,
1996. The Indenture will not restrict the incurrence of Senior Indebtedness or
other indebtedness by the Company or its Subsidiaries. The Notes will
effectively rank pari passu with the Company's 6% Convertible Subordinated
Notes due 2005.     
 
  The Indenture will provide that no payment may be made by the Company on
account of the principal of, premium, if any, and interest on the Notes, or to
acquire any of the Notes (including repurchases of Notes at the option of the
Holder) for cash or property (other than Junior Securities), or on account of
the redemption provisions of the Notes, (i) upon the maturity of any Senior
Indebtedness of the Company by lapse of time, acceleration (unless waived) or
otherwise, unless and until all principal of, premium, if any, and interest on
such Senior Indebtedness are first paid in full (or such payment is duly
provided for), or (ii) in the event of default in the payment of any principal
of, premium, if any, or interest on any Senior Indebtedness of the Company
when it becomes due and payable, whether at maturity or at a date fixed for
prepayment or by declaration or otherwise (a "Payment Default"), unless and
until such Payment Default has been cured or waived or otherwise has ceased to
exist.
 
  Upon (i) the happening of an event of default (other than a Payment Default)
that permits the holders of Senior Indebtedness or their representative
immediately to accelerate its maturity and (ii) written notice of such event
of default given to the Company and the Trustee by the holders of at least 25%
in the aggregate principal amount outstanding of such Senior Indebtedness or
their representative (a "Payment Notice"), then, unless and until such event
of default has been cured or waived or otherwise has ceased to exist, no
payment (by setoff or otherwise) may be made by or on behalf of the Company on
account of the principal of, premium, if any, interest on the Notes, or to
acquire or repurchase any of the Notes for cash or property, or on account of
the redemption provisions of the Notes, in any such case other than payments
made with Junior Securities of the Company. Notwithstanding the foregoing,
unless (i) the Senior Indebtedness in respect of which such Event of Default
exists has been declared due and payable in its entirety within 179 days after
the Payment Notice is delivered as set forth above (the "Payment Blockage
Period"), and (ii) such declaration has not been rescinded or waived, at the
end of the Payment Blockage Period, the Company shall be required to pay all
sums not paid to the Holders
 
                                      52
<PAGE>
 
of the Notes during the Payment Blockage Period due to the foregoing
prohibitions and to resume all other payments as and when due on the Notes.
Any number of Payment Notices may be given; provided, however, that (i) not
more than one Payment Notice shall be given within a period of any 360
consecutive days, and (ii) no event of default that existed upon the date of
such Payment Notice or the commencement of such Payment Blockage Period
(whether or not such event of default is on the same issue of Senior
Indebtedness) shall be made the basis for the commencement of any other
Payment Blockage Period.
 
  In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company (other than Junior Securities) shall be
received by the Trustee or the Holders at a time when such payment or
distribution is prohibited by the foregoing provisions, such payment or
distribution shall be held in trust for the benefit of the holders of Senior
Indebtedness of the Company, and shall be paid or delivered by the Trustee or
such Holders, as the case may be, to the holders of the Senior Indebtedness of
the Company remaining unpaid or unprovided for or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing any of such Senior Indebtedness of the
Company may have been issued, ratably according to the aggregate amounts
remaining unpaid on account of the Senior Indebtedness of the Company held or
represented by each, for application to the payment of all Senior Indebtedness
of the Company remaining unpaid, to the extent necessary to pay or to provide
for the payment of all such Senior Indebtedness in full after giving effect to
any concurrent payment or distribution to the holders of such Senior
Indebtedness.
 
  Upon any distribution of assets of the Company upon any dissolution, winding
up, total or partial liquidation or reorganization of the Company, whether
voluntary or involuntary, in bankruptcy, insolvency, receivership or a similar
proceeding or upon assignment for the benefit of creditors or any marshalling
of assets or liabilities, (i) the holders of all Senior Indebtedness of the
Company will first be entitled to receive payment in full (or have such
payment duly provided for) before the Holders are entitled to receive any
payment on account of the principal of, premium, if any, or interest on, the
Notes (other than Junior Securities) and (ii) any payment or distribution of
assets of the Company of any kind or character, whether in cash, property or
securities (other than Junior Securities) to which the Holders or the Trustee
on behalf of the Holders would be entitled (by setoff or otherwise), except
for the subordination provisions contained in the Indenture, will be paid by
the liquidating trustee or agent or other person making such a payment or
distribution directly to the holders of Senior Indebtedness of the Company or
their representative to the extent necessary to make payment in full of all
such Senior Indebtedness remaining unpaid, after giving effect to any
concurrent payment or distribution to the holders of such Senior Indebtedness.
 
  No provision contained in the Indenture or the Notes will affect the
obligation of the Company, which is absolute and unconditional, to pay, when
due, principal of, premium, if any, and interest on the Notes. The
subordination provisions of the Indenture and the Notes will not prevent the
occurrence of any Default or Event of Default under the Indenture or limit the
rights of the Trustee or any Holder, subject to the two preceding paragraphs,
to pursue any other rights or remedies with respect to the Notes.
 
  The Company conducts certain of its operations through its Subsidiaries.
Accordingly, the Company's ability to meet its cash obligations is dependent
upon the ability of its Subsidiaries to make cash distributions to the
Company. The ability of its Subsidiaries to make distributions to the Company
is and will continue to be restricted by, among other limitations, applicable
provisions of the laws of national and state governments and contractual
provisions. The Indenture will not limit the ability of the Company's
Subsidiaries to incur such restrictions in the future. The right of the
Company to participate in the assets of any Subsidiary (and thus the ability
of Holders of the Notes to benefit indirectly from such assets) is generally
subject to the prior claims of creditors, including trade creditors, of that
Subsidiary, except to the extent that the Company is recognized as a creditor
of such Subsidiary, in which case the Company's claims would still be subject
to any security interest of other creditors of such Subsidiary. The Notes,
therefore, will be subordinated by operation of law to creditors, including
trade creditors, of Subsidiaries of the Company with respect to the assets of
the Subsidiaries against which such creditors have a more direct claim.
 
                                      53
<PAGE>
 
  As a result of these subordination provisions, in the event of the
liquidation, bankruptcy, reorganization, insolvency, receivership or similar
proceeding or an assignment for the benefit of the creditors of the Company or
any of its Subsidiaries or a marshalling of assets or liabilities of the
Company and its Subsidiaries, Holders of the Notes may receive ratably less
than other creditors.
 
REDEMPTION AT THE COMPANY'S OPTION
 
  The Notes will not be subject to redemption prior to    , 1999. On and after
such date, the Notes will be redeemable at the option of the Company, in whole
or in part, upon not less than 30 nor more than 60 days notice to each Holder
of Notes, at the following redemption prices (expressed as percentages of the
principal amount) if redeemed during the 12-month period commencing    of the
years indicated below:
 
<TABLE>
<CAPTION>
           YEAR                                                      PERCENTAGE
      <S>                                                            <C>
      1999..........................................................       %
      2000 and thereafter...........................................       %
</TABLE>
 
in each case (subject to the right of Holders of record on a Record Date to
receive interest due on an Interest Payment Date that is on or prior to such
Redemption Date) together with accrued and unpaid interest, if any, to the
Redemption Date.
 
  In the case of a partial redemption, the Trustee shall select the Notes or
portions thereof for redemption on a pro rata basis, by lot or in such other
manner it deems appropriate and fair. The Notes may be redeemed in part in
multiples of $1,000 only.
 
  The Notes will not have the benefit of any sinking fund.
 
  Notice of any redemption will be sent, by first-class mail, at least 30 days
and not more than 60 days prior to the date fixed for redemption, to the
Holder of each Note to be redeemed to such Holder's last address as then shown
upon the registry books of the Registrar. The notice of redemption must state
the Redemption Date, the Redemption Price and the amount of accrued interest
to be paid. Any notice that relates to a Note to be redeemed in part only must
state the portion of the principal amount to be redeemed and must state that
on and after the Redemption Date, upon surrender of such Note, a new Note or
Notes in principal amount equal to the unredeemed portion thereof will be
issued. On and after the Redemption Date, interest will cease to accrue on the
Notes or portions thereof called for redemption, unless the Company defaults
in its obligations with respect thereto.
 
REPURCHASE OF NOTES AT THE OPTION OF THE HOLDER UPON A CHANGE OF CONTROL
 
  The Indenture will provide that in the event that a Change of Control (as
defined) has occurred, each Holder of Notes will have the right, at such
Holder's option, pursuant to an irrevocable and unconditional offer by the
Company (the "Repurchase Offer"), to require the Company to repurchase all or
any part of such Holder's Notes (provided that the principal amount of such
Notes must be $1,000 or an integral multiple thereof) on the date (the
"Repurchase Date") that is no later than 45 Business Days after the occurrence
of such Change of Control at a cash price (the "Repurchase Price") equal to
100% of the principal amount thereof, together with accrued and unpaid
interest to the Repurchase Date. The Repurchase Offer shall be made within 25
Business Days following a Change of Control and shall remain open for 20
Business Days following its commencement (the "Repurchase Offer Period"). Upon
expiration of the Repurchase Offer Period, the Company shall purchase all
Notes tendered in response to the Repurchase Offer. If required by applicable
law, the Repurchase Date and the Repurchase Offer Period may be extended as so
required; however, if so extended, it shall nevertheless constitute an Event
of Default if the Repurchase Date does not occur within 60 Business Days of
the Change of Control.
 
  The Indenture will provide that a "Change of Control" occurs upon any of the
following events: (i) upon any merger or consolidation of the Company with or
into any person or any sale, transfer or other conveyance, whether direct or
indirect, of all or substantially all of the assets of the Company, on a
consolidated basis, in one transaction or a series of related transactions,
if, immediately after giving effect to such transaction, any
 
                                      54
<PAGE>
 
"person" or "group" is or becomes the "beneficial owner," directly or
indirectly, of more than 50% of the total voting power in the aggregate
normally entitled to vote in the election of directors, managers, or trustees,
as applicable, of the transferee or surviving entity, (ii) when any "person"
or "group" is or becomes the "beneficial owner," directly or indirectly, of
more than 50% of the total voting power in the aggregate normally entitled to
vote in the election of directors of the Company, (iii) when, during any
period of 12 consecutive months after the Issue Date, individuals who at the
beginning of any such 12-month period constituted the Board of Directors of
the Company (together with any new directors whose election by such Board or
whose nomination for election by the stockholders of the Company was approved
by a vote of a majority of the directors then still in office who were either
directors at the beginning of such period or whose election or nomination for
election was previously so approved) cease for any reason to constitute a
majority of the Board of Directors of the Company then in office, (iv) a sale
or disposition, whether directly or indirectly, by the Company of all or
substantially all of its assets, or (v) the pro rata distribution by the
Company to its stockholders of substantially all of its assets.
 
  For purposes of this definition of "Change of Control," (i) the terms
"person" and "group" shall have the meaning used for purposes of Rules 13d-3
and 13d-5 of the Exchange Act as in effect on the Issue Date, whether or not
applicable; and (ii) the term "beneficial owner" shall have the meaning used
in Rules 13d-3 and 13d-5 under the Exchange Act as in effect on the Issue
Date, whether or not applicable, except that a "person" shall be deemed to
have "beneficial ownership" of all shares that any such person has the right
to acquire, whether such right is exercisable immediately or only after the
passage of time or upon the occurrence of certain events.
 
  The phrase "all or substantially all" of the assets of the Company is likely
to be interpreted by reference to applicable state law at the relevant time,
and will be dependent on the facts and circumstances existing at such time. As
a result, there may be a degree of uncertainty in ascertaining whether a sale
or transfer is of "all or substantially all" of the assets of the Company.
 
  On or before the Repurchase Date, the Company will (i) accept for payment
Notes or portions thereof properly tendered pursuant to the Repurchase Offer,
(ii) deposit with the Paying Agent cash sufficient to pay the Repurchase Price
(together with accrued and unpaid interest) of all Notes so tendered and (iii)
deliver to the Trustee Notes so accepted, together with an Officers'
Certificate listing the Notes or portions thereof being purchased by the
Company. The Paying Agent will promptly mail to the Holders of Notes so
accepted payment in an amount equal to the Repurchase Price (plus accrued and
unpaid interest), and the Trustee will promptly authenticate and mail or
deliver to such Holders a new Note or Notes equal in principal amount to any
unpurchased portion of the Notes surrendered. Any Notes not so accepted will
be promptly mailed or delivered by the Company to the Holder thereof. The
Company will publicly announce the results of the Repurchase Offer on or as
soon as practicable after the Repurchase Date.
 
  The Change of Control purchase feature of the Notes may make more difficult
or discourage a takeover of the Company, and, thus, the removal of incumbent
management. The Change of Control purchase feature resulted from negotiations
between the Company and the Underwriters.
 
  The provisions of the Indenture relating to a Change of Control may not
afford the Holders protection in the event of a highly leveraged transaction,
reorganization, restructuring, merger, spin-off or similar transaction that
may adversely affect Holders, if such transaction does not constitute a Change
of Control, as set forth above. In addition, the Company may not have
sufficient financial resources available to fulfill its obligation to
repurchase the Notes upon a Change of Control or to repurchase other debt
securities of the Company or its Subsidiaries providing similar rights to the
Holders thereof.
 
  To the extent applicable, the Company will comply with Section 14 of the
Exchange Act and the provisions of Regulation 14E and any other tender offer
rules under the Exchange Act and any other securities laws, rules and
regulations that may then be applicable to any offer by the Company to
purchase the Notes at the option of Holders upon a Change of Control.
 
                                      55
<PAGE>
 
LIMITATION ON MERGER, SALE OR CONSOLIDATION
 
  The Indenture will provide that the Company may not, directly or indirectly,
consolidate with or merge with or into another person or sell, lease, convey
or transfer all or substantially all of its assets (computed on a consolidated
basis), whether in a single transaction or a series of related transactions,
to another person or group of affiliated persons, unless (i) either (a) in the
case of a merger or consolidation, the Company is the surviving entity or (b)
the resulting, surviving or transferee entity is a corporation organized under
the laws of the United States, any state thereof or the District of Columbia
and expressly assumes by supplemental indenture all of the obligations of the
Company in connection with the Notes and the Indenture; (ii) no Default or
Event of Default shall exist or shall occur immediately after giving effect on
a pro forma basis to such transaction; and (iii) the resulting, surviving or
transferee entity immediately thereafter has a Consolidated Net Worth no less
than that of the Company immediately prior thereto.
 
  Upon any consolidation or merger or any transfer of all or substantially all
of the assets of the Company in accordance with the foregoing, the successor
corporation formed by such consolidation or into which the Company is merged
or to which such transfer is made, shall succeed to, and be substituted for,
and may exercise every right and power of, the Company under the Indenture
with the same effect as if such successor corporation had been named therein
as the Company, and the Company will be released from its obligations under
the Indenture and the Notes, except as to any obligations that arise from or
as a result of such transaction.
 
REPORTS
 
  Whether or not the Company is subject to the reporting requirements of
Section 13 or 15(d) of the Exchange Act, the Company shall deliver to the
Trustee and to each Holder, within 15 days after it is or would have been
required to file such with the Securities and Exchange Commission (the
"Commission"), annual and quarterly consolidated financial statements
substantially equivalent to financial statements that would have been included
in reports filed with the Commission if the Company was subject to the
requirements of Section 13 or 15(d) of the Exchange Act, including, with
respect to annual information only, a report thereon by the Company's
certified independent public accountants as such would be required in such
reports to the Commission and, in each case, together with a management's
discussion and analysis of results of operations and financial condition as
such would be so required.
 
EVENTS OF DEFAULT AND REMEDIES
 
  The Indenture will define an Event of Default as (i) the failure by the
Company to pay any installment of interest on the Notes as and when due and
payable and the continuance of any such failure for 30 days, (ii) the failure
by the Company to pay all or any part of the principal of, or premium, if any,
on the Notes when and as the same become due and payable at maturity,
redemption, by acceleration or otherwise, including, without limitation,
pursuant to any Repurchase Offer, (iii) the failure of the Company to perform
any conversion of Notes required under the Indenture and the continuance of
any such failure for 30 days, (iv) the failure by the Company to observe or
perform any other covenant or agreement contained in the Notes or the
Indenture and, subject to certain exceptions, the continuance of such failure
for a period of 60 days after written notice is given to the Company by the
Trustee or to the Company and the Trustee by the Holders of at least 25% in
aggregate principal amount of the Notes outstanding, (v) certain events of
bankruptcy, insolvency or reorganization in respect of the Company or any of
its Significant Subsidiaries, (vi) a default in the payment of principal,
premium or interest when due that extends beyond any stated period of grace
applicable thereto or an acceleration for any other reason of the maturity of
any Indebtedness of the Company or any of its Subsidiaries with an aggregate
principal amount in excess of $25 million, and (vii) final unsatisfied
judgments not covered by insurance aggregating in excess of $25 million, at
any one time rendered against the Company or any of its Subsidiaries and not
stayed, bonded or discharged within 75 days. The Indenture will provide that
if a Default occurs and is continuing, the Trustee must, within 90 days after
the occurrence of such default, give to the Holders notice of such default.
 
  The Indenture will provide that if an Event of Default occurs and is
continuing (other than an Event of Default specified in clause (v) above),
then in every such case, unless the principal of all of the Notes shall have
already become due and payable, either the Trustee or the Holders of 25% in
aggregate principal amount of the
 
                                      56
<PAGE>
 
Notes then outstanding, by notice in writing to the Company (and to the
Trustee if given by Holders) (an "Acceleration Notice"), may declare all
principal and accrued interest thereon to be due and payable immediately. If
an Event of Default specified in clause (v) above occurs, all principal and
accrued interest thereon will be immediately due and payable on all
outstanding Notes without any declaration or other act on the part of the
Trustee or the Holders. The Holders of no less than a majority in aggregate
principal amount of Notes generally are authorized to rescind such
acceleration if all existing Events of Default, other than the nonpayment of
the principal of, premium, if any, and interest on, the Notes that have become
due solely by such acceleration, have been cured or waived.
 
  Prior to the declaration of acceleration of the maturity of the Notes, the
Holders of a majority in aggregate principal amount of the Notes at the time
outstanding may waive on behalf of all the Holders any default, except a
default in the payment of principal of, premium, if any, or interest on any
Note not yet cured, or a default with respect to any covenant or provision
that cannot be modified or amended without the consent of the Holder of each
outstanding Note affected. Subject to the provisions of the Indenture relating
to the duties of the Trustee, the Trustee will be under no obligation to
exercise any of its rights or powers under the Indenture at the request, order
or direction of any of the Holders, unless such Holders have offered to the
Trustee reasonable security or indemnity. Subject to all provisions of the
Indenture and applicable law, the Holders of a majority in aggregate principal
amount of the Notes at the time outstanding will have the right to direct the
time, method and place of conducting any proceeding for any remedy available
to the Trustee, or exercising any trust or power conferred on the Trustee.
 
AMENDMENTS AND SUPPLEMENTS
 
  The Indenture will contain provisions permiting the Company and the Trustee
to enter into a supplemental indenture for certain limited purposes without
the consent of the Holders. With the consent of the Holders of not less than a
majority in aggregate principal amount of the Notes at the time outstanding,
the Company and the Trustee are permitted to amend or supplement the Indenture
or any supplemental indenture or modify the rights of the Holders; provided,
further, that no such modification may, without the consent of each Holder
affected thereby: (i) change the Stated Maturity of any Note or reduce the
principal amount thereof or the rate (or extend the time for payment) of
interest thereon or any premium payable upon the redemption thereof, or change
the place of payment where, or the coin or currency in which, any Note or any
premium or the interest thereon is payable, or impair the right to institute
suit for the enforcement of any such payment or the conversion of any Note on
or after the due date thereof (including, in the case of redemption, on or
after the Redemption Date), or reduce the Repurchase Price, or alter the
change of control provisions or redemption provisions in a manner adverse to
the Holders, (ii) reduce the percentage in principal amount of the outstanding
Notes, the consent of whose Holders is required for any such amendment,
supplemental indenture or waiver provided for in the Indenture, (iii)
adversely affect the right of such Holder to convert Notes, or (iv) modify any
of the waiver provisions, except to increase any required percentage or to
provide that certain other provisions of the Indenture cannot be modified or
waived without the consent of the Holder of each outstanding Note affected
thereby.
 
NO PERSONAL LIABILITY OF STOCKHOLDERS, OFFICERS, DIRECTORS AND EMPLOYEES
 
  The Indenture will provide that no past, present or future stockholder,
employee, officer or director, as such, of the Company or any successor
corporation shall have any personal liability in respect of the obligations of
the Company under the Indenture or the Notes by reason of his, her or its
status as such stockholder, employee, officer or director.
 
TRANSFER AND EXCHANGE
 
  A Holder may transfer or exchange the Notes in accordance with the
Indenture. The Company may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents, and to pay any taxes and fees
required by law or permitted by the Indenture. The Company is not required to
transfer or exchange any Notes selected for redemption. Also, the Company is
not required to transfer or exchange any Notes for a period of 15 days before
a selection of Notes to be redeemed.
 
  The registered Holder of a Note may be treated as the owner of it for all
purposes.
 
                                      57
<PAGE>
 
BOOK-ENTRY, DELIVERY AND FORM
 
  Except as set forth below, the Notes will initially be issued in the form of
one or more registered Notes in global form (the "Global Notes"). Each Global
Note will be deposited on the date of the closing of the sale of the Notes
(the "Closing Date") with, or on behalf of, The Depository Trust Company (the
"Depositary") and registered in the name of Cede & Co., as nominee of the
Depositary.
 
  The Company has been advised that the Depositary is a limited-purpose trust
company organized under the New York Banking Law, a "banking organization"
within the meaning of the New York Banking Law, a member of the Federal
Reserve System, a "clearing corporation" within the meaning of the New York
Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. The Depositary holds securities
that its participants ("Participants") deposit with it. The Depositary also
facilitates the settlement among Participants of securities transactions, such
as transfers and pledges, in deposited securities through electronic
computerized book-entry changes in Participants' accounts, thereby eliminating
the need for physical movement of securities certificates. Direct Participants
include securities brokers and dealers, banks, trust companies, clearing
corporations, and certain other organizations ("Direct Participants"). The
Depositary is owned by a number of its Direct Participants and by the New York
Stock Exchange, Inc., the American Stock Exchange, Inc. and the National
Association of Securities Dealers, Inc. Access to the Depository Trust Company
system is also available to others such as securities brokers and dealers,
banks and trust companies that clear through or maintain a custodial
relationship with a Direct Participant, either directly or indirectly
("Indirect Participants"). The rules applicable to the Depositary and its
Participants are on file with the Commission.
 
  The Company expects that pursuant to procedures established by the
Depositary (i) upon deposit of the Global Notes, the Depositary will credit
the accounts of Participants designated by the Underwriters with an interest
in the Global Note and (ii) ownership of the Notes evidenced by the Global
Notes will be shown on, and the transfer of ownership thereof will be effected
only through, records maintained by the Depositary (with respect to the
interests of Participants), the Participants and the Indirect Participants.
The laws of some states require that certain persons take physical delivery in
definitive form of securities that they own and that security interests in
negotiable instruments can only be perfected by delivery of certificates
representing the instruments. Consequently, the ability to transfer Notes
evidenced by the Global Note will be limited to such extent.
 
  So long as the Depositary or its nominee is the registered owner of a Note,
the Depositary or such nominee, as the case may be, will be considered the
sole owner or holder of the Notes represented by the Global Note for all
purposes under the Indenture. Except as provided below, owners of beneficial
interests in a Global Note will not be entitled to have Notes represented by
such Global Note registered in their names, will not receive or be entitled to
receive physical delivery of Certificated Notes, and will not be considered
the owners or holders thereof under the Indenture for any purpose, including
with respect to the giving of any directions, instructions or approvals to the
Trustee thereunder. As a result, the ability of a person having a beneficial
interest in Notes represented by a Global Note to pledge such interest to
persons or entities that do not participate in the Depositary's system, or to
otherwise take actions with respect to such interest, may be affected by the
lack of a physical certificate evidencing such interest.
 
  Neither the Company nor the Trustee will have any responsibility or
liability for any aspect of the records relating to or payments made on
account of Notes by the Depositary, or for maintaining, supervising or
reviewing any records of the Depositary relating to such Notes.
 
  Payments with respect to the principal of, premium, if any, and interest on,
any Note represented by a Global Note registered in the name of the Depositary
or its nominee on the applicable record date will be payable by the Trustee to
or at the direction of the Depositary or its nominee in its capacity as the
registered Holder of the Global Note representing such Notes under the
Indenture. Under the terms of the Indenture, the Company
 
                                      58
<PAGE>
 
and the Trustee may treat the persons in whose names the Notes, including the
Global Notes, are registered as the owners thereof for the purpose of
receiving such payments and for any and all other purposes whatsoever.
Consequently, neither the Company nor the Trustee has or will have any
responsibility or liability for the payment of such amounts to beneficial
owners of Notes (including principal, premium, if any, or interest), or to
immediately credit the accounts of the relevant Participants with such
payment, in amounts proportionate to their respective holdings in principal
amount of beneficial interests in the Global Note as shown on the records of
the Depositary. Payments by the Participants and the Indirect Participants to
the beneficial owners of Notes will be governed by standing instructions and
customary practice and will be the sole responsibility of the Participants or
the Indirect Participants.
 
 Certificated Notes
 
  If (i) the Company notifies the Trustee in writing that the Depositary is no
longer willing or able to act as a depositary and the Company is unable to
locate a qualified successor within 90 days or (ii) the Company, at its
option, notifies the Trustee in writing that it elects to cause the issuance
of Notes in definitive form under the Indenture, then, upon surrender by the
Depositary of the Global Notes, Certificated Notes will be issued to each
person that the Depositary identifies as the beneficial owner of the Notes
represented by Global Notes. In addition, subject to certain conditions, any
person having a beneficial interest in a Global Note may, upon request to the
Trustee, exchange such beneficial interest for Notes in the form of
Certificated Notes. Upon any such issuance, the Trustee is required to
register such Certificated Notes in the name of such person or persons (or the
nominee of any thereof), and cause the same to be delivered thereto.
 
  Neither the Company nor the Trustee shall be liable for any delay by the
Depositary or any Participant or Indirect Participant in identifying the
beneficial owners of the Notes, and the Company and the Trustee may
conclusively rely on, and shall be protected in relying on, instructions from
the Depositary for all purposes (including with respect to the registration
and delivery, and the respective principal amounts, of the Notes to be
issued).
 
  The information in this section concerning the Depositary and the
Depositary's book-entry system has been obtained from sources that the Company
believes to be reliable. The Company will have no responsibility for the
performance by the Depositary or its Participants of their respective
obligations as described hereunder or under the rules and procedures governing
their respective operations.
 
SAME-DAY FUNDS SETTLEMENT AND PAYMENT
 
  The Indenture will require that payments in respect of the Notes represented
by the Global Notes (including principal, premium, if any, and interest) be
made by wire transfer of immediately available funds to the accounts specified
by the Depositary. With respect to Notes represented by Certificated Notes,
the Company will make all payments of principal, premium, if any, and
interest, by mailing a check to each such Holder's registered address. The
Notes will trade in the Depositary's Same-Day Funds Settlement System until
maturity, or until the Notes are issued in certificated form, and secondary
market trading activity in the Notes will therefore be required by the
Depositary to settle in immediately available funds. No assurance can be given
as to the effect, if any, of settlement in immediately available funds on
trading activity in the Notes.

                         DESCRIPTION OF CAPITAL STOCK
 
GENERAL
   
  As of September 30, 1996, the Company was authorized to issue 150,000,000
shares of Common Stock, of which 50,009,131 shares were issued and
outstanding, and 3,000,000 shares of preferred stock, par value $.10 per
share, of which none were issued and outstanding. Of the unissued shares of
Common Stock as of such date, 4,390,000 shares were reserved for issuance upon
conversion of the Company's 5% Convertible Subordinated Debentures due 2000
(all of which were issued on October 25, 1996 in connection with a redemption
call), 7,636,363 shares were reserved for issuance upon conversion of the
Company's 6% Convertible Subordinated Notes due 2005 and an aggregate of
4,396,594 shares were reserved for issuance upon exercise of options either
outstanding or available for future grant under the Company's stock option
plans for employees and directors.     
 
COMMON STOCK
 
  The holders of Common Stock are entitled to one vote for each share held of
record by them on all matters to be voted on by stockholders. There is no
cumulative voting with respect to the election of directors; thus, the holders
of shares having more than 50% of the Company's voting power (including both
common and voting preferred shares) voting for the election of directors can
elect all of the directors. The holders of Common Stock are entitled to
receive dividends when, as and if declared by the Board of Directors out of
funds legally available therefor, subject to the prior rights of preferred
stockholders. In the event of liquidation, dissolution or winding up of the
Company's affairs, the holders of Common Stock are entitled to share ratably
in all assets remaining available for distribution to them after payment of
liabilities and after provision has been made for each class of stock,
including any preferred stock, that has preference over the Common Stock.
Except as described below under "Stock Purchase Rights," holders of shares of
Common Stock, as such, have no conversion, preemptive or other subscription
rights, and there are no redemption or sinking fund provisions applicable to
the Common Stock.
 
PREFERRED STOCK
 
  Shares of preferred stock may be issued without stockholder approval. The
Board of Directors is authorized to issue such shares in one or more series
and to fix the rights, preferences, privileges, qualifications, limitations
and restrictions thereof, including dividend rights and rates, conversion
rights, voting rights, terms of redemption, redemption prices, liquidation
preferences and the number of shares constituting any series or the
designation of such series, without any vote or action by the stockholders.
The Company has no current plans for the issuance of any shares of preferred
stock. Any preferred stock to be issued could rank prior to the Common Stock
with respect to dividend rights and rights of liquidation. The Board of
Directors, without stockholder approval, may issue preferred stock with voting
and conversion rights that could adversely affect the voting power of holders
of Common Stock or create impediments to persons seeking to gain control of
the Company.
 
STOCK PURCHASE RIGHTS
   
  Laidlaw, which, as of October 31, 1996, held 3,750,093 shares of Common
Stock, has certain rights to purchase voting securities of the Company in
order to maintain its percentage voting interest. Except in connection with
mergers or other acquisitions or in the ordinary course under an employee
stock option or stock bonus plan, in the event the Company proposes to sell or
issue shares of voting securities, Laidlaw has the right to purchase, on the
same terms as the proposed sale or issuance, that number of shares or rights
as will maintain its percentage interest in the voting securities of the
Company, assuming the conversion of all convertible securities and the
exercise of all options and warrants then outstanding. In addition, Laidlaw
has other purchase rights with respect to sales or issuances of securities by
the Company at prices below 85% of current market price at the time of sale or
issuance or the prevailing customary price for such securities or their
equivalent.     
 
CERTAIN VOTING ARRANGEMENTS
 
  Pursuant to the agreements whereby the Company acquired Smogless S.p.A. in
September 1994, Laidlaw has agreed to vote all shares owned by it for the
nominees of the Company's Board for election to the Board,
 
                                      62
<PAGE>
 
and on all other matters in the same proportion as the votes cast by other
holders of voting securities, other than those that relate to any business
combination or similar transaction involving the Company or any amendment to
the Company's Certificate of Incorporation or Bylaws.
 
CERTAIN CHARTER AND BYLAW PROVISIONS
 
  The Company's Certificate of Incorporation (the "Certificate") places
certain restrictions on the voting rights of a "Related Person," defined
therein as any person who directly or indirectly owns 5% or more of the
outstanding voting stock of the Company. The founders and the original
directors of the Company are excluded from the definition of "Related
Persons," as are seven named individuals including Richard J. Heckmann, the
Chairman of the Board, President and Chief Executive Officer of the Company.
These voting restrictions apply in two situations. First, the vote of a
director who is also a Related Person is not counted in the vote of the Board
of Directors to call a meeting of stockholders where that meeting will
consider a proposal made by the Related Person director. Second, any
amendments to the Certificate that relate to specified Articles therein (those
dealing with corporate governance, limitation of director liability or
amendments to the Certificate), in addition to being approved by the Board of
Directors and a majority of the Company's outstanding voting stock, must also
be approved by either (i) a majority of directors who are not Related Persons,
or (ii) the holders of at least 80% of the Company's outstanding voting stock,
provided that if the change was proposed by or on behalf of a Related Person,
then approval by the holders of a majority of the outstanding voting stock not
held by Related Persons is also required. In addition, any amendment to the
Company's Bylaws must be approved by one of the methods specified in clauses
(i) and (ii) in the preceding sentence.
 
  The Certificate and the Company's Bylaws provide that the Board of Directors
shall fix the number of directors and that the Board shall be divided into
three classes, each consisting of one-third of the total number of directors
(or as nearly as may be possible). Stockholders may not take action by written
consent. Meetings of stockholders may be called only by the Board of Directors
(or by a majority of its members). Stockholder proposals, including director
nominations, may be considered at a meeting only if written notice of that
proposal is delivered to the Company from 30 to 60 days in advance of the
meeting, or within ten days after notice of the meeting is first given to
stockholders.
 
DELAWARE ANTI-TAKEOVER LAW
 
  Section 203 of the Delaware General Corporation Law ("Section 203")
provides, in general, that a stockholder acquiring more than 15% of the
outstanding voting shares of a corporation subject to the statute (an
"Interested Stockholder"), but less than 85% of such shares, may not engage in
certain "Business Combinations" with the corporation for a period of three
years subsequent to the date on which the stockholder became an Interested
Stockholder unless (i) prior to such date the corporation's board of directors
has approved either the Business Combination or the transaction in which the
stockholder became an Interested Stockholder or (ii) the Business Combination
is approved by the corporation's board of directors and authorized by a vote
of at least two-thirds of the outstanding voting stock of the corporation not
owned by the Interested Stockholder.
 
  Section 203 defines the term "Business Combination" to encompass a wide
variety of transactions with or caused by an Interested Stockholder in which
the Interested Stockholder receives or could receive a benefit on other than a
pro rata basis with other stockholders, including mergers, certain asset
sales, certain issuances of additional shares to the Interested Stockholder,
transactions with the corporation that increase the proportionate interest of
the Interested Stockholder or transactions in which the Interested Stockholder
receives certain other benefits.
 
  These provisions could have the effect of delaying, deferring or preventing
a change of control of the Company. The Company's stockholders, by adopting an
amendment to the Certificate or Bylaws of the Company, may elect not to be
governed by Section 203, effective twelve months after adoption. Neither the
Certificate nor the Bylaws of the Company currently excludes the Company from
the restrictions imposed by Section 203.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES
   
  The following is a summary of certain Federal income tax considerations for
original purchasers of the Notes and is based on a review and analysis of the
Federal income tax law now in effect, which is subject to change, possibly
retroactively. This summary does not discuss all aspects of Federal income
taxation that may be relevant to particular holders of Notes in light of their
individual investment circumstances or to certain types of investors subject
to special tax rules (e.g., financial institutions, insurance companies, tax-
exempt organizations, and foreign taxpayers), nor does it discuss any aspects
of state, local or foreign tax law consequences. This summary assumes that
investors will hold their Notes as "capital assets" (generally, property held
for investment) under the Internal Revenue Code of 1986, as amended.
Prospective purchasers are urged to consult their tax advisors regarding the
specific Federal, state, local, and foreign income and other tax consequences
of purchasing, holding, converting, and disposing of the Notes.     
 
SALE OR EXCHANGE
 
  A holder will recognize capital gain or loss upon the sale or other
disposition of a Note in an amount equal to the difference between the amount
realized from such disposition and his tax basis in the Note. Such gain or
loss will be long-term if the Note has been held for more than one year.
 
CONVERSION
 
  A holder's conversion of a Note into Common Stock is generally not a taxable
event (except with respect to cash received in lieu of a fractional share).
The holder's tax basis in the Common Stock received on conversion of a Note
will be the same as the holder's tax basis in the Note at the time of
conversion (exclusive of any tax basis allocable to a fractional share), and
the holding period for the Common Stock received on conversion will include
the holding period of the Note converted.
 
CONSTRUCTIVE DIVIDEND
 
  If at any time the Company makes a distribution of property to shareholders
that would be taxable to such shareholders as a dividend for Federal income
tax purposes and, in accordance with the antidilution provisions of the Notes,
the Conversion Price of the Notes is decreased, the amount of such decrease
may be deemed to be the payment of a taxable dividend to holders. For example,
a decrease in the Conversion Price in the event of distributions of evidence
of indebtedness or assets of the Company will generally result in deemed
dividend treatment to holders, but generally a decrease in the event of stock
dividends or the distribution of rights to subscribe for shares will not. See
"Description of the Notes--Conversion Rights."

</TABLE>    
 
  The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase and accept delivery of the Notes offered hereby are
subject to approval of certain legal matters by counsel and to certain other
conditions. If any of the Notes are purchased by the Underwriters pursuant to
the Underwriting Agreement, all such Notes (other than those covered by the
over-allotment option described below) must be purchased.
 
  The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute
to payments that the Underwriters may be required to make in respect thereof.
 
  The Representatives have advised the Company that the Underwriters propose
to offer the Notes to the public initially at the price set forth on the cover
page of this Prospectus and to certain dealers (who may include the
Underwriters) at such price, less a concession not in excess of    % of the
principal amount of the Notes. The Underwriters may allow, and such dealers
may re-allow, discounts not in excess of    % of the principal amount of the
Notes to any other Underwriter and certain other dealers. After the Offerings,
the offering price and other selling terms may be changed by the Underwriters.
   
  The Company has granted to the Underwriters an option to purchase up to an
additional $30,000,000 aggregate principal amount of the Notes, at the initial
public offering price less underwriting discounts and commissions, solely to
cover over-allotments. Such option may be exercised at any time until 30 days
after the date of this Prospectus. To the extent that the Underwriters
exercise such option, each of the Underwriters will be committed, subject to
certain conditions, to purchase an amount of Notes proportionate to such
Underwriter's initial commitment as indicated in the preceding table.     
   
  The Company and its executive officers and directors, and certain other
stockholders, who collectively are the beneficial owners of an aggregate of
9,532,217 shares of Common Stock, have agreed, subject to certain exceptions,
with the Underwriters not to, directly or indirectly, offer, sell, contract to
sell, grant any option to purchase or otherwise dispose of, without the prior
written consent of Donaldson, Lufkin & Jenrette Securities Corporation
("DLJ"), any shares of Common Stock or any securities convertible into or
exercisable or exchangeable for, or warrants, options or rights to purchase or
acquire, Common Stock or in any other manner transfer all or a portion of the
economic consequences associated with the ownership of any Common Stock, or
enter into any agreement to do any of the foregoing, for a period of 90 days
after the date of this Prospectus.     
 
  The Notes will constitute a new issue of securities with no established
trading market. The Underwriters presently intend to make a market in the
Notes. However, the Underwriters are not obligated to do so and any market-
making activities may be discontinued at any time without notice. Application
will be made to list the Notes on the New York Stock Exchange. However, no
assurance can be given that an active trading market for the Notes will
develop or, if such market develops, as to the liquidity or sustainability of
such market.

                         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, 1995 and 1996, 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,
1996. 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 Davis Water & Waste Industries, Inc.,
which statements reflect total assets constituting 17 percent and 9 percent in
1995 and 1996, respectively, and total revenues constituting 49 percent, 42
percent and 31 percent in 1994, 1995 and 1996, 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 Davis Water & Waste Industries,
Inc., is based solely on the report of the other 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 and the report of the other
auditors 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, 1995 and 1996, and the results of their
operations and their cash flows for each of the years in the three-year period
ended March 31, 1996, in conformity with generally accepted accounting
principles.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
of DAVIS WATER & WASTE INDUSTRIES, Inc.
 
  In our opinion, the consolidated balance sheet and the related consolidated
statements of operations, of changes in stockholders' equity and of cash flows
of Davis Water & Waste Industries, Inc. and its subsidiaries (not presented
seperately herein) present fairly, in all material respects, their financial
position at April 30, 1996 and 1995, and the results of their operations and
their cash flows for each of the three years in the period ended April 30,
1996, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for the
opinion expressed above. We have not audited the consolidated financial
statements of Davis Water & Waste Industries, Inc. and its subsidiaries for
any period subsequent to April 30, 1996.

               UNITED STATES FILTER CORPORATION AND SUBSIDIARIES
 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
    
              YEARS ENDED MARCH 31, 1994, 1995 AND 1996 AND THE 
             SIX MONTHS ENDED SEPTEMBER 30, 1996 (UNAUDITED)     
 
(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
principally 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 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 enacted 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 foreign subsidiaries as such earnings are intended to be indefinitely
reinvested in those operations.
 
FOREIGN CURRENCY TRANSLATION
 
  In accordance with Statement of Financial Accounting Standard No. 52,
"Foreign Currency Translation," the assets and liabilities denominated in
foreign currency 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. The transaction gains and losses
included in net income (loss) are immaterial.
 
INVENTORIES
 
  Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out method.
 
                                     F-11

               UNITED STATES FILTER CORPORATION AND SUBSIDIARIES
 
            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 3 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.
 
COST IN EXCESS OF NET ASSETS OF BUSINESSES ACQUIRED
 
  Cost in excess of net assets of businesses acquired is amortized on the
straight-line method principally over 40 years. The Company evaluates the
recoverability of these costs based upon expectations of nondiscounted cash
flows and operating income of each subsidiary. Based upon its most recent
analysis, the Company believes that no material impairment exists at March 31,
1996.
 
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 $1,735,000 and $5,450,000 at
March 31, 1995 and 1996, respectively, have been deferred and are being
amortized over the term of the related convertible subordinated debentures
(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 securities.
 
RECLASSIFICATIONS
 
  Certain amounts in the 1995 consolidated financial statements have been
reclassified to conform with the 1996 presentation.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 
UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS
   
  The consolidated financial statements for the three months ended June 30,
1995 and 1996 are unaudited. In the opinion of management, all adjustments,
consisting only of normal recurring items, considered necessary for a fair
presentation have been included. Certain information and footnote disclosures
normally included in financial statements have been condensed or omitted from
the interim consolidated financial statements. The results of operations for
the six months ended September 30, 1996 are not necessarily indicative of the
results that may be expected for the year ending March 31, 1997.     
 
INCOME (LOSS) PER COMMON SHARE
 
  Income (loss) per common share is computed based on the weighted average
number of shares outstanding. Common stock equivalents consisting of
convertible preferred stock and options are included in the computation of
income (loss) per share when their effect is dilutive.
 
  Primary and fully diluted income (loss) per common share were calculated as
follows:

  Cash equivalents consist of demand deposits and certificates of deposit with
original maturities of 90 days or less.
 
(3) SHORT-TERM INVESTMENTS
 
  Short-term investments consist of highly liquid municipal issues with
original maturities of more than 90 days when purchased, and are carried at
amortized cost, which approximates market value.

  During fiscal 1996, the Company's Zimpro subsidiary (note 9) evaluated the
ongoing value of equipment in accordance with Statement of Financial
Accounting Standards No. 121, Accounting for the Impairment of Long-Lived
Assets and Long-Lived Assets to be Disposed Of ("FAS 121"). Based upon this
evaluation, it was determined that certain equipment with a carrying value of

  The above amounts reflect accumulated amortization of $4,600,000 and
$1,982,000 at March 31, 1995 and 1996, respectively. The carrying amount of
these other assets approximate their fair value.
 
  During fiscal 1996, the Company's Zimpro subsidiary evaluated the ongoing
value of certain patents in accordance with FAS 121. Based upon this
evaluation, it was determined that patents with a carrying value of $3,556,000
were impaired and were written down by $2,648,000 to their estimated fair
value.
 
  During the fourth quarter of fiscal 1994, the Company's Davis subsidiary
(note 9) adopted a plan to shutdown or reorganize the operations of its
wholly-owned subsidiary, The Taulman Company ("Taulman"). The pre-tax loss
provision for these actions recorded in fiscal 1994 includes the write-off of
intangible assets totaling $2,908,000 associated with Taulman and the accrual
of $5,987,000 to provide for anticipated losses during the shutdown period.
During fiscal 1995, an additional $678,000 was added to the accrual for future
anticipated losses.
 
  The Taulman shutdown represents the discontinuation of a product line.
Therefore, Taulman's results of operations through the fourth quarter of
fiscal 1994 were included as components of continuing operations in the
consolidated statement of operations for fiscal 1994. Taulman's results of
operations during fiscal 1995, 1996 and in future periods have been or will be
charged against the reserve for anticipated losses during the shutdown period.
As of March 31, 1996 the balance in the reserve was $2,082,000. Certain

("Smogless") from Laidlaw, Inc. The total consideration for the acquisition of
Smogless (excluding acquisition costs of $396,000) consists of the following:
(i) $45,000,000 in aggregate principal amount of subordinated debt of Ionpure
Italy due August 31, 2001 and bearing interest at 6.5% for the period January
1, 1995 through September 30, 1995 and 4.5% thereafter, (ii) common stock
purchase warrants exercisable in whole or part at any time on or before August

principal amount of subordinated debt for each share of common stock, (iii)
185,185 shares of a new Series B Voting Convertible Preferred Stock, (iv)
27,000 shares of the Company's common stock, and (v) $700,000 in cash.
 
  Smogless is headquartered in Milan, Italy and provides a broad range of
services for wastewater treatment, including feasibility studies, process
evaluation, plant design, construction and commissioning and design of
specialized machinery.
 
  The acquisition of Smogless has been accounted for as a purchase and,
accordingly, the results of operations of Smogless for the 7 months ended
March 31, 1995 are included in the Company's consolidated statement of
operations for the year ended March 31, 1995. The excess of cost over fair
value of net assets acquired was approximately $39,340,000 and is being

  All pro forma information presented above is in response to applicable
accounting rules relating to business acquisitions. This pro forma information
does not purport to be indicative of the results that actually would have been
obtained if the combined operations had been conducted during the periods
presented and is not intended to be a projection of future results due to
extensive changes being made in the organization, facilities, personnel and
other costs of the acquired companies.
   
  On December 1, 1993, the Company acquired all of the outstanding capital
stock of Ionpure Technologies Corporation and IP Holdings Company. The total
purchase price consisted of $100,000 in cash and 4,561,638 shares of Company
Common Stock. In fiscal 1995, the Company received an independent appraisal of
the value of the Company's Common Stock. As a result of the appraisal, shares
issued in connection with this acquisition had a value $9,123,000 less than
originally ascribed to the Common Stock at the time of acquisition.
Accordingly, additional paid in capital and excess cost over fair value of net
assets acquired were reduced in fiscal 1995.

  As of March 31, 1996, the Company has net operating loss carryforwards in
France of approximately $19,952,000. Approximately $1,946,000 of the operating
losses expire in the years 1997-1998, while the remainder have an indefinite
carryforward period. Any benefit of the French loss carryforward must be
shared equally between the Company and Alcoa until March 31, 1997. As of March
31, 1996, the Company also has net operating loss carryforwards in other
European countries of approximately $7,338,000 which expire from 1997 to 2002.
 
  As of March 31, 1996, the Company also has net operating loss carryforwards
generated from Liquipure of $14,362,000, which has been recognized in fiscal
1996. These loss carryforwards expire from 2002 to 2007. In addition, the
Company has net operating loss carryforwards generated from Zimpro of
$2,905,000, which have not been recognized due to the uncertainty as to future
realizability of these carryforwards. These loss carryforwards expire in 2009.
 
  The Company also has available, at March 31, 1996, other net operating loss
and foreign tax credit carryforwards for U.S. Federal income tax purposes of
approximately $13,552,000 which expire in 1999 to 2010.

  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, 1996 of companies with strong earnings potential. A valuation
allowance of $19,946,000 at March 31, 1996 has been recognized and consists
primarily of state and foreign net operating losses which may not be realized
prior to their expiration periods.
 
(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 $4,709,000, 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

COMMON STOCK
 
  On December 5, 1994, the Company paid in the form of a stock dividend a 3-
for-2 split of the Company's common stock. The par value of the new shares
issued was $50,000 which was transferred from additional paid-in-capital to
the common stock account. All references to income (loss) per share and other
common stock
information in the accompanying consolidated financial statements and notes
thereto have been restated to reflect the 3-for-2 split.
 
  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 before other related expenses, were $98,118,000.
 
  On July 15, 1996, the Company paid in the form of a stock dividend a 3-for-2
split of the Company's common stock. All references to income (loss) per share
and other common stock information in the accompanying consolidated financial
statements and notes thereto have been restated to reflect the 3-for-2 split.
 
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 authorized 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.
 
  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 $80,000, $122,000 and $112,000 was recorded in 1994, 1995 and 1996,
respectively, related to the Directors Plan.

(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 Employee
Retirement Income Security Act of 1974 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.
 
  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
accrued. Defined contribution plan expense to the Company was $519,000,
$810,000 and $1,631,000 for the years ended March 31, 1994, 1995 and 1996,
respectively.
 
  The Company's Davis subsidiary had a defined benefit pension plan covering
substantially all of its employees. Upon acquisition of Davis by the Company,
the defined benefit pension plan was frozen and all liabilities have been
fully accrued. The pension plan expense for prior years was not significant.
 
(17) BUSINESS SEGMENT DATA AND EXPORT SALES
 
  The Company's sole business segment is the design, manufacture, operation,
distribution and service of equipment and supplies for filtration, water
treatment and wastewater treatment for industrial and municipal customers.
 
  There were no sales to any individual customers which accounted for 10% or
more of revenue in fiscal 1994, 1995 and 1996.
 
  Export sales accounted for $28,881,000, $37,940,000 and $58,560,000 in
fiscal 1994, 1995 and 1996, 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 facility was
acquired by the Company as part of its acquisition of Polymetrics on October
2, 1995 (note 9). 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.
   
  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.

The Board of Directors
Wheelabrator Technologies Inc.:
 
The Board of Directors
United States Filter Corporation:
 
  We have audited the accompanying combined balance sheets of the Systems and
Manufacturing Group of Wheelabrator Technologies Inc. (the "Businesses") as of
December 31, 1994 and 1995, and the related combined statements of income and
cash flows for each of the years in the three-year period ended December 31,
1995. These financial statements are the responsibility of the management of
the Businesses. Our responsibility is to express an opinion on these 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 combined financial statements referred to above present
fairly, in all material respects, the financial position of the Systems and
Manufacturing Group of Wheelabrator Technologies Inc. as of December 31, 1994
and 1995 and the results of its operations and its cash flows for each of the
years in the three-year period ended December 31, 1995, in conformity with
generally accepted accounting principles.

                    NOTES TO COMBINED FINANCIAL STATEMENTS
 
NOTE 1 BUSINESS DESCRIPTION AND BASIS OF PRESENTATION
 
  The Systems and Manufacturing Group (the "Businesses") of Wheelabrator
Technologies Inc. ("WTI") provide products and services to customers in the
water, wastewater and general industrial markets, primarily in the United
States, Europe and Asia. The majority of the Businesses have been acquired by
WTI in the last three years. Certain other Businesses have been owned by WTI
or its predecessors since prior to 1993. The Businesses have no separate legal
status or existence. The assets and liabilities comprising the majority of the
U.S. based Businesses are owned by a wholly owned subsidiary of WTI.
 
  In connection with a proposed transaction whereby WTI would sell the
Businesses to United States Filter Corporation ("USF"), WTI and USF have
entered into a definitive Purchase and Sale Agreement dated September 14, 1996
(the "Agreement"), the terms of which provide for certain assets to be
purchased and certain liabilities assumed by USF in connection with Businesses
based in the United States. Additionally, the Agreement provides for certain
liabilities relating to the Businesses to be retained by WTI and for WTI to
indemnify USF in connection with certain other matters (collectively the
"Retained Liabilities"). These financial statements reflect the financial
condition, results of operations and cash flows for the Businesses on a
combined basis, excluding the Retained Liabilities, for all periods presented.
 
NOTE 2 SIGNIFICANT ACCOUNT POLICIES
 
 Combined Financial Statements
 
  The combined financial statements include the accounts of the Businesses and
the majority-owned subsidiaries. All significant intercompany transactions and
balances have been eliminated. Investments in affiliates WTI does not control
are accounted for using the equity method.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect reported amounts of assets, liabilities, income,
expenses and disclosures of contingencies. Future events could alter such
estimates.
 
 Concentrations
 
  The Businesses offer a multitude of products and services to a diverse
customer base. Management believes the Businesses have no significant
customer, supplier, product line, credit risk, geographic or other
concentrations that could expose the Businesses to adverse, near-term severe
financial impacts.
 
 Revenue Recognition
 
  Revenues from certain long-term engineering and equipment supply contracts
are recognized on the percentage-of-completion basis, with estimated losses
recognized in full when identified. All other revenues are recognized when
services are rendered or products are shipped.
 
 Foreign Currency
 
  Foreign subsidiaries' income statement accounts are translated at the
average exchange rates in effect during the period, while assets and
liabilities are translated at the rates of exchange at the balance sheet date.
The resulting balance sheet translation adjustments are charged or credited
directly to group equity. Foreign exchange transaction gains and losses
realized during 1993, 1994 and 1995 were not significant.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(CONTINUED)
 
 
 Combined Statements of Cash Flows
 
  For purposes of the Combined Statements of Cash Flows, all highly liquid
instruments purchased with an original maturity of three months or less are
considered to be cash equivalents.
 
 Derivative Financial Instruments
 
  From time to time, the Businesses use derivative instruments to manage
currency risk. Immaterial amounts of various currencies were sold forward for
delivery at various dates in 1995 to hedge foreign exchange exposure on
specifically identified transactions. Gains or losses on these transactions
are included in the measurement of the subsequent transaction. Where deemed
advantageous, management will enter similar hedges in the future to mitigate
foreign exchange exposure.
 
 Fair Value of Financial Instruments
 
  Financial instruments of the Businesses consist primarily of cash and cash
equivalents, receivables and accounts payable. The book values of such
instruments are considered to be representative of their respective fair
values.
 
 Inventories
 
  Inventories are stated at the lower of cost (first-in, first-out method) or
market (net realizable value).
 
 Property, Plant and Equipment
 
  Property, plant, and equipment (including major improvements) are
capitalized and stated at cost. Items of an ordinary maintenance or repair
nature are charged directly to operating expense. The cost less estimated
salvage value of property, plant, and equipment is generally depreciated on a
straight-line basis over estimated useful lives that range from 3 to 35 years.
 
 Goodwill
 
  The excess of cost over fair value of the net assets of acquired businesses
("goodwill") is amortized on a straight-line basis over 40 years. The
accumulated amortization balances as of December 31, 1994 and 1995 were $8.2
million and $12.2 million, respectively. On an ongoing basis, the
realizability of goodwill is measured by the ability of the acquired
businesses to generate current and undiscounted expected future cash flows in
excess of unamortized goodwill. If such realizability were in doubt, an
adjustment would be made to reduce the carrying value of the goodwill. No such
adjustments have been made with respect to the Businesses.
 
 Pro Forma Income Taxes
 
  Certain of the assets and liabilities comprising the Businesses are not
stand alone, taxable entities (see Note 1). The taxable income from Businesses
operating in the United States have been included in the consolidated federal
tax returns of WTI for all periods presented. Entities outside the United
States are taxable in the jurisdictions in which they are organized or are
doing business. For the purposes of the accompanying combined financial
statements, a pro forma income tax expense has been provided at 40 percent of
reported combined pretax income.

</TABLE>
 
  All contracts in process are expected to be billed and collected within two
years.
 
  Accounts receivable include retainage that has been billed but is not due
until completion pursuant to the terms of the contract. Such retainage at
December 31, 1995 was $3.7 million, all of which (except for amounts provided
for) is expected to be collected within one year. At December 31, 1994,
retainage was $3.0 million.
 
 Accounting Pronouncements
 
  Effective January 1, 1994, the Businesses adopted Statement of Financial
Accounting Standards No. 112 "Employers' Accounting for Postemployment
Benefits" ("FAS 112"). This new statement established accounting standards for
employers who provide benefits to former or inactive employees after
employment but before retirement. The adoption of FAS 112 did not have a
material impact on the combined financial statements of the Businesses since
its accounting prior to adoption of FAS 112 was substantially in compliance
with the new standard. Also effective during 1994 was Statement of Financial
Accounting Standards No. 115, "Accounting for Certain Debt and Equity
Securities" ("FAS 115"). The Businesses do not have significant investments
and does not contemplate acquiring significant investments of the type covered
in FAS 115.
 
  The Businesses are required to adopt Statement of Financial Accounting
Standards No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of" ("FAS 121"), beginning in 1996.
Management does not believe the adoption of FAS 121 will have a material
impact on the combined financial statements of the Businesses.
 
 Unaudited Interim Information
   
  The combined financial statements as of September 30, 1996 and for the nine
months ended September 30, 1995 and 1996 are unaudited. In the opinion of
management, the unaudited combined financial statements reflect all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation. Certain information and footnote disclosures normally
included in financial statements have been condensed or omitted from the
interim combined financial statements. The results of operations for the nine
months ended September 30, 1996 are not necessarily indicative of the results
that may be expected for the year ending December 31, 1996.

 Cash Management
 
  Certain of the Businesses participate in WTI's centralized cash management
system and, as such, their cash funding requirements have been met by WTI and
all excess cash has been transferred to WTI.
 
 Allocations
 
  The combined income statements includes all direct costs of the Businesses
as well as certain corporate costs directly identified with the Businesses.
WTI has not allocated interest income or expense to the Businesses. In the
opinion of management, these allocations have been made on a basis which is
believed to be reasonable for a group of businesses operating within the
structure of a larger parent organization. However, the allocations are not
necessarily indicative of the level of expenses which might have been incurred
by the Businesses operating as a stand-alone entity.
 
NOTE 4. ACQUISITIONS
 
  The Businesses include three environmental services businesses acquired in
1993, six acquired in 1994 and one acquired in 1996 in exchange for
consideration, net of cash acquired and including assumed debt, of
approximately $24.8 million, $21.5 million and $5.7 million, respectively. The
Businesses utilize the purchase method of accounting, and the purchase price
of the acquisitions has been allocated to their respective net assets based
upon estimated fair market values. The results of operations of acquired
entities have been included in the Businesses' combined financial statements
from their respective dates of acquisition. The pro forma effect of the
acquisitions made during 1993, 1994 and 1995 was not material.
 
NOTE 5. PRO FORMA INCOME TAXES
 
  The Businesses reported income before income tax for each of the years
indicated on the accompanying combined statements of income. During such
periods, the Businesses operating in the United States were included in WTI's
consolidated federal income tax returns. Those Businesses located outside of
the United States are taxable in the jurisdictions in which they are
organized. For the purposes of the accompanying combined financial statements,
a pro forma income tax expense has been provided at 40% of reported combined
pretax income.

NOTE 6. BENEFIT PLANS
 
  Substantially all employees based in the United States are participants in
the Wheelabrator-Rust Savings and Retirement Plan, which is a qualified
defined contribution plan consisting of a contributory component and a non-
contributory component. Under the terms of the contributory component,
eligible employees may elect to contribute a portion of their annual
compensation and the Businesses are required to match a minimum of 30 percent
of the first six percent of eligible compensation contributed by an employee.
Under the terms of the non-contributory component, eligible employees receive
an annual contribution equal to a minimum of three percent of their eligible
earnings. The Businesses' contributions to such plans during 1993, 1994 and
1995 amounted to approximately $1.7 million, $2.1 million and $2.4 million,
respectively.
 
  The Businesses based outside the United States have in place various other
plans that are not significant that provide pension and welfare benefits to
certain active and former employees.

NOTE 8. COMMITMENTS AND CONTINGENCIES
 
  There are various lawsuits and claims pending against the Businesses that
have arisen in the normal course of business and related mainly to matters of
product liability, personal injury, and property damage. The outcomes of these
matters are not presently determinable, but in the opinion of management,
based on the advice of counsel, the ultimate resolution of these matters will
not have a material adverse effect on the financial condition or results of
operations of the Businesses.
 
  The Businesses are self-insured for general liability claims up to $2.0
million per occurrence. Liability insurance in effect during the last several
years provides coverage for environmental matters only to a limited extent. In
the normal course of business, the Businesses have issued or are parties to
bank letters of credit, performance bonds, and other guarantees.
 
  Certain of the Businesses operate in the environmental industry and are
involved with the protection of the environment. As such, a significant
portion of the Businesses' operating costs and capital expenditures could be
characterized as costs of environmental protection. While the Businesses are
faced, in the normal course of its business, with the need to expend funds for
environmental protection, it is not expected that such expenditures will have
a material adverse effect on financial condition or results of operations.

         STATEMENT OF UNITED UTILITIES PLC DIRECTORS' RESPONSIBILITIES
 
  The directors have assumed the responsibility to prepare financial
statements for each financial year which present fairly the financial position
of the division and of the profit or loss of the division for that period. In
preparing those financial statements, the directors are required to:
 
  .  select suitable accounting policies and then apply them consistently;
 
  .  make judgements and estimates that are reasonable and prudent;
 
  .  state whether applicable accounting standards have been followed,
     subject to any material departures disclosed and explained in the
     financial statements;
 
  .  prepare the financial statements on the going concern basis unless it is
     inappropriate to presume that the companies within the division will
     continue in business.
 
  The directors are responsible for maintaining proper accounting records
which disclose with reasonable accuracy at any time the financial position of
the division and to enable them to ensure that the financial statements comply
with relevant aspects of the Companies Act 1985. They are also responsible for
safeguarding the assets of the division and hence for taking reasonable steps
for the prevention and detection of fraud and other irregularities.

AUDITORS' REPORT TO THE BOARD OF DIRECTORS OF UNITED UTILITIES PLC
 
  We have audited the accompanying aggregated balance sheets of the United
Utilities PLC Process Division as at 31 March 1996 and 31 March 1995, the
related aggregated profit and loss accounts for each of the years in the two
year period ended 31 March 1996 and the cash flow for the year ended 31 March
1996. These aggregated financial statements are the responsibility of the
Directors of United Utilities PLC. Our responsibility is to express an opinion
on these aggregated financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards in the United Kingdom which are substantially the same as auditing
standards generally accepted in the United States. Those standards require
that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free from 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 aggregated financial statements referred to above
present fairly, in all material respects, the financial position of the United
Utilities PLC Process Division at 31 March 1996 and 31 March 1995, the results
of its operations for each of the years in the two year period ended 31 March
1996 and the cash flow for the year ended 31 March 1996 in conformity with
generally accepted accounting principles in the United Kingdom.

                                     NOTES
                  (FORMING PART OF THE FINANCIAL STATEMENTS)
 
1. ACCOUNTING POLICIES
 
BASIS OF PREPARATION OF FINANCIAL STATEMENTS
 
  The aggregated financial statements incorporate the financial statements of
each of the entities which constitute the Process Division of United Utilities
PLC as detailed in note 21. The financial statements have been prepared under
the historical cost convention and in accordance with applicable accounting
standards and with UK generally accepted accounting principles.
 
BASIS OF AGGREGATION
 
  The Process Division is composed of the entities set out in note 21, all of
which are owned by United Utilities PLC. There is no single holding company
for the Process Division.
 
  The figures presented in these financial statements have been prepared by
combining the results of all these entities. All intra group Process Division
transactions and balances have been eliminated. As the Process Division is not
a statutory entity, directors emoluments have not been disclosed.
 
CASH FLOW STATEMENT
 
  As its parent undertaking, United Utilities PLC, publishes a consolidated
cash flow statement, the Process Division is exempt, under Financial Reporting
Standard 1, from preparing such a statement. Notwithstanding this exemption, a
cash flow statement has been provided for the year ended 31 March 1996.
Comparative cash flow information, which would have been required had the
exemption not been available, has not been provided.
 
UNAUDITED INTERIM AGGREGATED FINANCIAL STATEMENTS
   
  The aggregated financial statements for the six months ended 30 September,
1995 and 1996 are unaudited. In the opinion of management, all adjustments,
consisting only of normal recurring items, considered necessary for a fair
presentation have been included. Certain information and all footnote
disclosures normally included in financial statements have been excluded from
the interim aggregated financial statements. The results of operations for the
six months ended 30 September, 1996 are not necessarily indicative of the
results that may be expected for the year ending 31 March, 1997.     
 
TURNOVER
 
  Turnover represents the income receivable in the ordinary course of business
for goods or services provided and excludes VAT and foreign sales tax.
 
RESEARCH AND DEVELOPMENT
 
  Expenditure on research and development is written off against profits in
the year in which it is incurred. Development expenditure incurred on projects
which meet the criteria of SSAP 13 is capitalized and amortized over 5 years.
 
GOODWILL
 
  The net assets of companies and businesses acquired are incorporated into
the aggregated financial statements at their fair value to the Process
Division and after adjustments to bring the accounting policies of the
companies and businesses acquired into alignment with those of the Division.
Past fair value adjustments include provisions for reorganisation and
restructuring costs. In the year ended 31 March 1996, in accordance with
 
                                     F-45

                                     NOTES
                  (FORMING PART OF THE FINANCIAL STATEMENTS)
 
Financial Reporting Standard 7, reorganisation and restructuring costs have
not been included in fair value adjustments. If the estimates on which these
provisions are based prove to be in excess of actual expenditure, the
unutilised surplus provisions will not be taken to profit and loss, but will
be credited to reserves as a recalculation of goodwill.
 
TANGIBLE FIXED ASSETS
 
  Additions are included at cost.
 
  Freehold land is not depreciated. Other assets are depreciated evenly over
their estimated economic lives which are principally as follows:
 
<TABLE>
   <S>                                                               <C>
   Buildings........................................................ 30-60 years
   Fixtures, fittings, tools, equipment and motor vehicles..........  3-40 years
   Capitalised computer software costs..............................  3-10 years
</TABLE>
 
LEASED ASSETS
 
  Assets financed by leasing arrangements which transfer substantially all the
risks and rewards of ownership to the lessee (finance leases) are capitalised
in the balance sheet and the corresponding capital cost is shown as an
obligation to the lessor. Leasing repayments comprise both a capital and a
finance element. The finance element is written off to the profit and loss
account so as to produce an approximately constant periodic rate of charge on
the outstanding obligation. Such assets are depreciated over the shorter of
their estimated useful lives and the period of the lease.
 
  Operating lease rentals are charged to the profit and loss account on a
straight line basis over the period of the lease.
 
FIXED ASSET INVESTMENTS
 
  Investments held as fixed assets are stated at cost less amounts written off
for permanent diminution.
 
STOCKS
 
  Stocks are stated at cost less any provision necessary to recognise damage
and obsolescence.
 
  Long term contract work in progress is stated at cost, net of amounts
transferred to cost of sales, after deducting payments received in advance and
making provision for foreseeable losses.
 
  Finished goods and goods for resale are stated at the lower of cost,
including appropriate production overheads, and net realisable value.
 
PENSIONS
 
  Approximately half of the Division's employees belong to pension schemes
which provide for defined benefits based on final pensionable pay. Pension
costs are charged against profits over the estimated remaining service lives
of employees.
 
FOREIGN CURRENCY
 
  For the convenience of the reader, these financial statements have been
stated in US dollars. The balance sheets have been translated into dollars at
exchange rates applicable at the year end. The profit and loss accounts are
translated into dollars using the average rate. Differences arising from the
application of the closing rate to opening net assets, offset by translation
differences on foreign currency loans which finance investments in overseas
subsidiary undertakings, together with differences between profits and losses
translated at average rates and at closing rates, are recorded as a movement
in reserves.

DEFERRED TAXATION
 
  Provision is made for deferred taxation where a liability is considered
likely to arise in the foreseeable future.
 
ASSOCIATED UNDERTAKINGS
 
  The appropriate share of the results of associated undertakings is
recognised in the aggregated profit and loss account where the directors
consider that the Division is in a position to exert significant influence
over the associated undertakings.
 
REVALUATION RESERVE
 
  Surpluses or deficits arising as a result of the incorporation of land and
buildings valuations in the accounts are taken to the revaluation reserve
unless the deficit exceeds the accumulated surpluses when it would be taken
directly to the profit and loss account.
 
2. TURNOVER, PROFIT AND NET ASSETS BY BUSINESS
 
  Turnover, loss or profit before interest and taxation and net assets were
all attributable to the same class of business namely Process Equipment.

                  (FORMING PART OF THE FINANCIAL STATEMENTS)
 
 
  A revaluation of the freehold land and buildings at the Tonbridge site of
Wallace & Tiernan Limited as at 31 March 1996 was undertaken by King Sturge &
Co., an independent firm of qualified chartered surveyors. The valuation was
made in accordance with the Royal Institute of Chartered Surveyors Statements
of Asset Valuation Practice. The valuation of the operational part of the site
was on a depreciated replacement cost basis and the non-operational part on an
open market value basis.
 
  No capital gains tax is expected to arise in the event of a sale of the site
and hence no deferred tax is currently provided in respect of this
revaluation.
 
  If the land and buildings had not been revalued to $8,700,000 (1995:
$10,850,000) they would have been shown at their historical cost net book
value of $1,120,000 (1995: $1,052,000).

22. PENSIONS
 
  The Process Division operates a number of pension schemes in the UK, the
USA, Europe, Australia and Canada. The major schemes are of the defined
benefit type.
 
  Edwards & Jones Limited operated two pension schemes in 1993 providing
retirement benefits for its employees and directors. The funds of both schemes
were transferred into the Water Pension Scheme, a defined benefit scheme,
operated by United Utilities PLC, during 1993/94. Contributions are based on
the pension costs of all United Kingdom subsidiary undertakings of United
Utilities PLC participating in the Water Pension Scheme. The accounts of
United Utilities PLC contain particulars of the current actuarial position of
the Water Pension Scheme.
 
  Since 1 January 1990, Wallace & Tiernan Limited and substantially all its
employees have subscribed to the Wallace & Tiernan Pension Scheme, which is a
funded defined benefit scheme providing benefits based on

final pensionable pay. Contributions to the scheme are charged to the profit
and loss account so as to spread the cost of pensions over employees' working
lives with the company. The contributions are determined by a qualified
actuary. The most recent valuation was undertaken as at 1 July 1994 by the
scheme's actuary. The valuation method used for the calculation of normal
costs and liabilities was the projected unit method, while that used for the
assets was the discounted expected cash flow method. The assumptions which
have the most significant effect on the results of the valuation are those
relating to the rates of return on investments and salary and pension
increases. It was assumed that the investment returns would be 9% per annum,
that the rate of salary increase would be 7% per annum, and that pensions
would increase at the rate of 3% per annum.
 
  The market value of scheme assets at the date of the valuation was
(Pounds)9,638,000 and the actuarial value of those assets represented
approximately 95% of the benefits that had accrued to members after allowing
for expected future increases in earnings. It is intended that this deficit,
amounting to (Pounds)543,000 will be eliminated by additional company
contributions over a period of 13 years.
 
  For the non UK schemes the defined benefit arrangements have been reviewed
on consistent assumptions and any balance of surplus spread forward to derive
the pension cost.
 
23. ULTIMATE PARENT COMPANY
 
  The ultimate parent undertaking of all the entities in the Process Division
is United Utilities PLC, a company registered in England. Copies of the United
Utilities PLC accounts are available from the registered office at Dawson
House, Great Sankey, Warrington, WA5 3LW, United Kingdom. The accounts of
United Utilities PLC represent the largest and smallest consolidation within

    ACCOUNTING PRINCIPLES
 
  These aggregated financial statements have been prepared in accordance with
UK GAAP which differs in certain significant respects from US GAAP. The
significant differences as they relate to the United Utilities PLC Process
Division, are summarised in the following paragraphs.
 
 Statement of cash flows: Basis of Preparation
 
  United Utilities PLC Process Division's statement of cash flows is prepared
in accordance with UK Financial Reporting Standard 1 (FRS 1), the objectives
and principles of which are similar to those set out in Statement of Financial
Accounting Standards 95 (SFAS 95), "Statement of Cash Flows" under US GAAP.
The principal differences between FRS 1 and SFAS 95 relate to classification.
 
  Cash flows from taxation and returns on investments and servicing of finance
under FRS 1 would be included as operating activities under SFAS 95. Under FRS
1 net cash and cash equivalents include short-term borrowings repayable within
three months from the date of their advance. Under SFAS 95 short-term
borrowings repayable within three months from the date of their advance and
overdraft balances would not be included within cash and cash equivalents and
movements on those borrowings and overdraft balances would be included in
financing activities.
 
PROVISIONS
 
  In the US there are strict rules about the timing of recognition of on-going
restructuring costs; whereas in the UK there is at present some flexibility.
Given that restructuring provisions can involve very large costs, the
differences can be significant.

                                     NOTES
                  (FORMING PART OF THE FINANCIAL STATEMENTS)
 
 
FIXED ASSET REVALUATION
 
  In the US fixed assets must be carried at depreciated cost whereas in the UK
fixed assets may be revalued. Depreciation would then be booked on the
revalued amount.
 
DEVELOPMENT EXPENDITURE
 
  In the US the rules prohibit the carrying of development costs as an asset.
In the UK they may, at the company's option, be carried as an asset if the
following criteria are met:
 
  .  there is a clearly defined project;
 
  .  the related costs are separately identifiable;
 
  .  there is a reasonable certainty that the project is technically feasible
     and commercially viable;
 
  .  future revenues are reasonably expected to exceed future development,
     production, selling and administration costs;
 
  .  adequate financial resources exist to complete the project.
 
GOODWILL
 
  In the US positive goodwill is treated in the same way as any other acquired
intangible. Such assets must be capitalised and subsequently amortised over
their expected useful lives which may not exceed 40 years.
 
  In the UK positive goodwill may be written off directly against reserves
which is the policy adopted by the Process Division.

ITEM 17. UNDERTAKINGS.     
   
  The undersigned registrant hereby undertakes:     
   
  (a) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:     
     
    (i) To include any prospectus required by section 10(a)(3) of the
  Securities Act of 1933;     
     
    (ii) To reflect in the prospectus any facts or events arising after the
  effective date of the registration statement (or the most recent post-
  effective amendment thereof) which, individually or in the aggregate,
  represent a fundamental change in the information set forth in the
  registration statement. Notwithstanding the foregoing, any increase or
  decrease in volume of securities offered (if the total dollar value of
  securities offered would not exceed that which was registered) and any
  deviation from the low or high end of the estimated maximum offering range
  may be reflected in the form of prospectus filed with the Commission
  pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
  price represent no more than a 20% change in the maximum aggregate offering
  price set forth in the "Calculation of Registration Fee" table in the
  effective registration statement;     
     
    (iii) To include any material information with respect to the plan of
  distribution not previously disclosed in the registration statement or any
  material change to such information in the registration statement.     
   
  Provided, however, that paragraphs (a)(i) and (a)(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed by the registrant pursuant to
section 13 or section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in the registration statement.     
   
  (b) That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at the time shall be deemed to be the initial bona
fide offering thereof.     
   
  (c) To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.     
   
  The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act
of 1934) that is incorporated by reference in the registration statement shall
be deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.     
   
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

  The undersigned registrant hereby undertakes that:     
   
  (1) For the purpose of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this registration
statement as of the time it was declared effective.     
   
  (2) For the purpose of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

Ladies and Gentlemen:

          United States Filter Corporation, a Delaware corporation (the
"Company"), confirms its agreement with the several underwriters listed in
Schedule I hereto (the "Underwriters"), for whom Donaldson, Lufkin & Jenrette
Securities Corporation ("DLJ"), Deutsche Morgan Grenfell Inc., NatWest

("Smith Barney") have been duly authorized to act as representatives (the
"Representatives"), as follows:

          1.   The Securities.  Subject to the terms and conditions herein set
               --------------

2001 (the "Firm Securities").  The Company also proposes to sell to the U.S.

                                       
<PAGE>
 
Underwriters not more than $30,000,000 aggregate principal amount of additional
___% Convertible Subordinated Notes due 2001, of the Company (the "Additional
Securities" and, together with the Firm Securities, the "Securities"), if
requested by the Underwriters as provided in Sections 3 and 4 hereof.  The
Securities are to be issued pursuant to the provisions of an Indenture to be
dated as of _________________, 1996, by and between the Company and State Street
Bank and Trust Company of California, N.A., as trustee (the "Trustee") (the
"Indenture"), pursuant to which the Securities will be convertible at the option
of the holders thereof, into Shares of the Common Stock (as defined below).
Prior to or concurrently with the issuance and sale of the Securities (as
defined below) the Company will issue and sell 10,000,000 shares of Common
Stock, par value $.01 per share, of the Company (the "Common Stock") (excluding
1,500,000 additional shares of Common Stock subject to an overallotment option)
(the "Common Stock Offering").

          2.   Registration Statement and Prospectus.  The Company has prepared
               -------------------------------------                           
and filed with the Securities and Exchange Commission (the "Commission") in
accordance with the provisions of the Securities Act of 1933, as amended, and
the rules and regulations of the Commission promulgated pursuant thereto
(collectively, the "Act"), a registration statement on Form S-3 (No. 333-[
]), with respect to the Securities including the Common Stock issuable upon
conversion thereof, including a preliminary prospectus, subject to completion,
relating to the Securities including the Common Stock issuable upon conversion
thereof.  The registration statement, as amended at the time it becomes
effective or, if a post-effective amendment is filed with respect thereto, as
amended by such post-effective amendment at the time of its effectiveness
(including in each case all documents incorporated or deemed incorporated by
reference therein, if any, all financial statements and exhibits, and the
information, if any, contained in a prospectus or term sheet subsequently filed
with the Commission pursuant to Rule 424(b) under the Act and deemed to be a
part of the registration statement at the time of its effectiveness pursuant to
Rule 430A or Rule 434 under the Act (as applicable), and any additional
registration statement relating to the issuance of additional Securities filed
pursuant to Rule 462(b) under the Act, is hereinafter referred to as the
"Registration Statement;" and the prospectus, constituting a part of the
Registration Statement at the time it became effective, or such revised
prospectus as shall be provided to the Underwriters for use in connection with
the offering of the Securities including the Common Stock issuable upon
conversion thereof that differs from the prospectus on file with the Commission
at the time the Registration Statement became effective including, in each case,
all documents incorporated or deemed incorporated by reference therein, if any,
and including 

                                       2
<PAGE>
 
any prospectus subject to completion and any term sheet meeting the requirements
of Rule 434(c), filed pursuant to Rule 424(b), in the form used to confirm sales
of the Securities, whether or not filed with the Commission pursuant to Rule
424(b) under the Act, is hereinafter referred to as the "Prospectus."

          3.   Agreements to Sell and Purchase.  On the basis of the
               -------------------------------                      
representations and warranties contained in this Agreement, and subject to its
terms and conditions, the Company agrees to issue and sell, and each Underwriter
agrees, severally and not jointly, to purchase from the Company, the Firm
Securities in the respective amounts set forth opposite their names on Schedule
I hereto, at a purchase price equal to [_____%] of the principal amount thereof
(the "Purchase Price").

          On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company agrees to issue
and sell to the Underwriters, and the Underwriters shall have a right to
purchase, severally and not jointly, up to all of the Additional Securities from
the Company at the Purchase Price.  Additional Securities may be purchased, from
time to time, as provided in Section 4 hereof solely for the purpose of covering
over-allotments made in connection with the offering of the Firm Securities.
Each Underwriter, severally and not jointly, agrees to purchase the principal
amount of Additional Securities (subject to such adjustment to eliminate partial
Securities as the Underwriters may determine) which bears the same proportion to
the total principal amount of Additional Securities to be purchased as the
principal amount of Firm Securities set forth opposite the name of such
Underwriter in Schedule I hereto bears to the total principal amount of Firm
Securities.

          The Company shall deliver, concurrently with the execution of this
Agreement, an agreement executed by (i) each of the Company's directors,
officers and stockholders listed on Schedule II hereto, pursuant to which each
such person agrees, not to, directly or indirectly, offer, sell, contract to
sell, grant any warrant, right, or option to purchase or sell or otherwise
dispose of without the prior written consent of DLJ, any shares of Common Stock,
or any securities convertible into or exercisable or exchangeable for, or
warrants, options, or rights to purchase or acquire, Common Stock owned by such
person, or in any other manner transfer all or a portion of the economic
consequences associated with the ownership of any Common Stock, or enter into
any agreement to do any of the foregoing or file a registration statement with
respect to any of the foregoing, for a period of 90 days after the date of the
Prospectus, except pursuant to this Agreement.

          4.  Delivery and Payment.  Delivery to you of and payment for the Firm
              --------------------                                              
Securities shall be made at 9:00 A.M., New York City time, on the third business
day, unless otherwise permitted by the Commission pursuant to Rule 15c6-1 under
the Securities Exchange Act of 1934, as amended, and the rules and regulations
of the Commission thereunder (collectively, the "Exchange Act") (such time and
date being referred to as the "Closing Date") following the date of the public
offering of the Firm Securities as advised by the Representatives to the
Company, at such place as you shall reasonably designate.  The Closing Date and
the location of delivery of the Firm Securities may be varied by agreement
between the Representatives and the Company.

          Delivery to the Underwriters of and payment for any Additional
Securities to be purchased by the Underwriters shall be made at such place as
the Representatives shall designate in writing, at 9:00 A.M., New York City
time, on such date or dates (individually, an "Option Closing Date"), which may
be the same as the Closing Date but shall in no event be earlier than the
Closing Date, as shall be specified in a written notice from the Representatives
to the Company of the Underwriters' determination to purchase a certain
principle amount, specified in said notice, of Additional Securities.  The date
or dates specified in any such notice shall be a business day no later than ten
business days after such notice has been given and no earlier than two business
days after such notice has been given.  Any such notice may be given at any time
not later than 30 days after the date of this Agreement.  Any Option Closing
Date and the location of delivery of and payment for the Additional Securities
may be varied by agreement among the Representatives and the Company.

          The Securities in definitive form shall be registered in such names
and issued in such denominations as you shall request in writing not later than
two full business days prior to the Closing Date or the applicable Option
Closing Date, as the case may be, and shall be made available to you at such
place as you shall reasonably request for inspection not later than 9:30 A.M.,
New York City time, on the business day next preceding the Closing Date or the
applicable Option Closing Date, as the case may be.  The Securities shall be
delivered to you on the Closing Date or the applicable Option Closing Date, as
the case may be, with any transfer taxes payable upon initial issuance thereof
duly paid by the Company, for your account against payment of the Purchase Price
in currently available funds to the order of the Company.

          5.   Agreements of the Company.  The Company agrees with each of the
               -------------------------                                      
Underwriters and the Selling Stockholders that:

          (a) It will, if the Registration Statement has not heretofore become
     effective under the Act, file an amendment to the Registration Statement
     or, if necessary pursuant to Rule 430A under the Act, a post-effective
     amendment to the Registration Statement, in each case as soon as
     practicable after the execution and delivery of this Agreement, and will
     use its best efforts to cause the Registration Statement or such post-
     effective amendment to become effective at the earliest possible time. The
     Company will comply fully and in a timely manner with the applicable
     provisions of Rule 424, Rule 430A, and, if applicable, Rule 434, and Rule
     462, under the Act.

          (b) It will advise you promptly and, if requested by you, confirm such
     advice in writing, (i) when the Registration Statement has become
     effective, if and when the Prospectus is sent for filing pursuant to Rule
     424 under the Act and when any post-effective amendment to the Registration
     Statement becomes effective, (ii) of the receipt of any comments from the
     Commission or any state securities commission or regulatory authority that
     relate to the Registration Statement or requests by the Commission or any
     state securities commission or regulatory authority for amendments to the
     Registration Statement or amendments or supplements to the Prospectus or
     for additional information, (iii) of the issuance by the Commission of any
     stop order suspending the effectiveness of the Registration Statement, or
     of the suspension of qualification of the Securities, including the Common
     Stock issuable upon conversion thereof, for offering or sale in any
     jurisdiction, or the initiation of any proceeding for such purpose by the
     Commission or any state securities commission or other regulatory
     authority, and (iv) of the happening of any event during such period as in
     your judgment the Underwriters are required to deliver a prospectus in
     connection with sales of the Securities, including the Common Stock
     issuable upon conversion thereof, which makes any statement of a material
     fact made in the Registration Statement untrue or which requires the making
     of any additions to or changes in the Registration Statement (as amended or
     supplemented from time to time) in order to make the statements therein not
     misleading or that makes any statement of a material fact made in the
     Prospectus (as amended or supplemented from time to time) untrue or which
     requires the making of any additions to or changes in the Prospectus 

                                       5
<PAGE>
 
     (as amended or supplemented from time to time) in order to make the
     statements therein, in light of the circumstances under which they were
     made, not misleading. The Company shall use its best efforts to prevent the
     issuance of any stop order by the Commission or order suspending the
     qualification or exemption of the Securities, including the Common Stock
     issuable upon conversion thereof, under any state securities or Blue Sky
     laws, and, if at any time the Commission shall issue any stop order
     suspending the effectiveness of the Registration Statement, or any state
     securities commission or other regulatory authority shall issue an order
     suspending the qualification or exemption of the Securities, including the
     Common Stock issuable upon conversion thereof, under any state securities
     or Blue Sky laws, the Company shall use every reasonable effort to obtain
     the withdrawal or lifting of such order at the earliest possible time.

          (c) It will furnish to you without charge five (5) copies of the
     signed copies of the Registration Statement as first filed with the
     Commission and of each amendment to it, including all exhibits filed
     therewith, and will furnish to you such number of conformed copies of the
     Registration Statement as so filed and of each amendment to it, without
     exhibits, as you may reasonably request.

          (d) It will not file any amendment or supplement to the Registration
     Statement, whether before or after the time when it becomes effective, or
     make any amendment or supplement to the Prospectus, of which you shall not
     previously have been advised and provided a copy within two business days
     prior to the filing thereof or to which you shall reasonably object; and it
     will prepare and file with the Commission, promptly upon your reasonable
     request, any amendment to the Registration Statement or supplement to the
     Prospectus which may be necessary or advisable in connection with the
     distribution of the Securities by you, and will use its best efforts to
     cause any amendment to the Registration Statement to become effective
     promptly.

          (e) Promptly after the Registration Statement becomes effective, and
     from time to time thereafter for such period as in the opinion of counsel
     for the Underwriters a prospectus is required by law to be delivered in
     connection with sales of the Securities by the Underwriters, it will
     furnish to each Underwriter and dealer without charge as many copies of the
     Prospectus (and of any amendment or supplement to the Prospectus) as such

                                       6
<PAGE>
 
     Underwriters and dealers may reasonably request for the purposes
     contemplated by the Act. So long as the same is delivered or used pursuant
     to applicable law, the Company consents to the use of the Prospectus and
     any amendment or supplement thereto by any Underwriter or any dealer, both
     in connection with the offering or sale of the Securities and for such
     period of time thereafter as the Prospectus is required by the Act or the
     Exchange Act to be delivered in connection therewith.

          (f) If during such period specified in paragraph (e) any event shall
     occur as a result of which, in the opinion of counsel for the Underwriters,
     it becomes necessary to amend or supplement the Prospectus in order to make
     the statements therein, in the light of the circumstances existing when the
     Prospectus is delivered to a purchaser, not misleading, or if it is
     necessary to amend or supplement the Prospectus to comply with any law, it
     will promptly prepare and file with the Commission an appropriate amendment
     or supplement to the Prospectus so that the statements in the Prospectus,
     as so amended or supplemented, will not, in the light of the circumstances
     when the Prospectus is so delivered, be misleading, and will comply with
     law, and will furnish to each Underwriter and dealer without charge such
     number of copies thereof as such Underwriters and dealers may reasonably
     request.

          (g) Prior to any public offering of the Securities, it will cooperate
     with you and your counsel in connection with the registration or
     qualification of the Securities, including the Common Stock to be issued
     upon conversion thereof, for offer and sale by the Underwriters under the
     state securities or Blue Sky laws of such jurisdictions as you may
     reasonably request (provided, that the Company shall not be obligated to
                         --------                                            
     qualify as a foreign corporation in any jurisdiction in which it is not so
     qualified or to take any action that would subject it to general consent to
     service of process in any jurisdiction or subject it to taxation generally
     in respect of doing business in any jurisdiction in which it is not now so
     subject).  The Company will continue such qualification in effect so long
     as required by law for distribution of the Securities, including the Common
     Stock to be issued upon conversion thereof.  The Company will inform the
     Florida Department of Banking and Finance if, prior to the completion of
     the distribution of the Securities by the Underwriters, the Company
     commences engaging in business with the government of Cuba or with any
     person or affiliate located in Cuba.  Such information will be provided
     within 90 days of the com-

                                       7

     mencement thereof or after a change to any such previously reported
     information.

          (h) It will make generally available to its security holders as soon
     as reasonably practicable a consolidated earnings statement covering a
     period of at least twelve months beginning after the "effective date" (as
     defined in Rule 158 under the Act) of the Registration Statement (but in no
     event commencing later than 90 days after such date) which shall satisfy
     the provisions of Section 11(a) of the Act and Rule 158 thereunder and will
     advise you in writing when such statement has been so made available.

          (i) During the period of five years after the date of this Agreement,
     (i) it will furnish as soon as reasonably practicable after the end of each
     fiscal year to the record holders of its Common Stock a financial report of
     the Company and its subsidiaries on a consolidated basis (and a similar
     financial report of all unconsolidated subsidiaries, if any), all such
     financial reports to include a consolidated balance sheet, a consolidated
     statement of operations, a consolidated statement of cash flows and a
     consolidated statement of stockholders' equity as of the end of and for
     such fiscal year, together with comparable information as of the end of and
     for the preceding year, certified by independent certified public
     accountants, and (ii) it will make generally available as soon as
     reasonably practicable after the end of each quarterly period (except for
     the last quarterly period of each fiscal year) to such holders, a
     consolidated balance sheet, a consolidated statement of operations and a
     consolidated statement of cash flows (and similar financial reports of all
     unconsolidated subsidiaries, if any) as of the end of and for such period,
     and for the period from the beginning of such year to the close of such
     quarterly period, together with comparable information for the
     corresponding periods of the preceding year.

          (j) During the period referred to in paragraph (i), it will furnish to
     you as soon as available a copy of each report or other publicly available
     information of the Company mailed to the holders of Common Stock or filed
     with the Commission and such other publicly available information
     concerning the Company and its subsidiaries as you may reasonably request.

          (k) Whether or not the transactions contemplated hereby are
     consummated or this Agreement is terminated, it will pay and be responsi-

                                       8

     ble for all costs, expenses and fees in connection with or incident to (i)

     all amendments or supplements thereto, (ii) the printing and delivery of
     this Agreement, any memoranda describing state securities or Blue Sky laws
     and all other agreements, memoranda, correspondence and other documents

     Underwriters relating to such printing and delivery), (iii) the
     registration with the Commission and the issuance and delivery of the
     Securities, including the Common Stock issuable upon conversion thereof,
     (iv) the registration or qualification of the Securities, including the
     Common Stock issuable upon conversion thereof, for offer and sale under the

     (g) above (including, in each case, the fees and disbursements (including
     filing fees) of counsel relating to such registration or qualification and
     blue sky memoranda relating thereto), (v) furnishing such copies of the
     Registration Statement, Prospectus and preliminary prospectus, and all
     amendments and supplements to the Underwriters or any dealers to whom
     Securities may be sold prior to or during the period specified in paragraph
     5(e), as may be reasonably requested by you, (vi) any filing fees incurred
     in connection with the filing, registration and clearance with the National
     Association of Securities Dealers, Inc. (the "NASD") in connection with the
     offering of the Securities, including the Common Stock issuable upon
     conversion thereof, (vii) the listing of the Securities, including the
     Common Stock issuable upon conversion thereof, on the New York Stock
     Exchange, and (viii) the performance by the Company of its other
     obligations under this Agreement, the cost of its personnel and other
     internal costs and the cost of printing and engraving the certificates
     representing the Securities and any shares of Common Stock to be issued
     upon Conversion of the Securities and all expenses and taxes incident to
     the Sale and delivery of the Securities to the Underwriters; provided, that
                                                                  --------
     the Company shall have no liability or obligation with respect to any fees
     or expenses of counsel to the Underwriters, except as provided in clause
     (iv) above, or for any costs of personnel or other internal costs of the
     Underwriters.

          (l) It will use the proceeds from the sale of the Securities in the

<PAGE>
 
          (m) It will cause the Securities to be listed on the New York Stock
     Exchange and will use its reasonable best efforts to maintain such listing
     while any of the Securities are outstanding.

          (n) It will cause the Common Stock issuable upon conversion of the
     Securities to be listed on the New York Stock Exchange and will use its
     best efforts to maintain such listing for a period of five years after the
     effective date of the Registration Statement.

          (o) It will not voluntarily claim, and will not actively resist any
     attempts to claim, the benefit of any usury laws against the holders of the
     Securities.

          (p) It will use all reasonable efforts to do and perform all things
     required or necessary to be done and performed under this Agreement by it
     prior to or after the Closing Date or any Option Closing Date, as the case
     may be, and to satisfy all conditions precedent on its part to the delivery
     of the Securities.

          6.   Representations and Warranties of the Company.  The Company
               ---------------------------------------------              
represents and warrants to each Underwriter that:

          (a) The Company and the transactions contemplated by this Agreement
     meet the requirements for using Form S-3 under the Act.  The Registration
     Statement has become effective; no stop order suspending the effectiveness
     of the Registration Statement is in effect, and no proceedings for such
     purpose are pending before or threatened by the Commission.

          (b) Each part of the Registration Statement where such part became
     effective, did not contain and each such part, as amended or supplemented,
     it applicable, will not contain any untrue statement of a material fact or
     omit to state a material fact required to be stated therein or necessary to
     make the statements therein not misleading, (ii) the Registration Statement
     and the Prospectus comply and, as amended or supplemented, if applicable,
     will comply in all material respects with the requirements of the Act, and
     (iii) the Prospectus does not contain and, as amended or supplemented, if
     applicable, will not contain any untrue statement of a material fact or
     omit to state a material fact necessary to make the statements therein, in
     the light of the circumstances under which they were 

                                       10
<PAGE>
 
     made, not misleading, except that the representations and warranties set
     forth in this paragraph (b) do not apply to statements or omissions from
     the Registration Statement or the Prospectus based upon and in conformity
     with information relating to any Underwriter furnished to the Company in
     writing by such Underwriter through you expressly for use therein or the
     Statement of Eligibility and Qualification of the Trustee on Form T-1 (the
     "Form T-1"). The Company acknowledges for all purposes under this Agreement
     (including this paragraph and Section 7 hereof) that the statements with
     respect to price and underwriting discount and the last paragraph on the
     cover page of the Prospectus and the statements set forth in the [_________
     paragraph] under the caption "Underwriting" in the Prospectus constitute
     the only written information furnished to the Company by the Underwriters
     for use in the Registration Statement or the Prospectus or any preliminary
     prospectus, or any amendment or supplement to them (the "Underwriter
     Information") and that the Underwriters shall not be deemed to have
     provided any information (and therefore are not responsible for any
     statement or omission) pertaining to any arrangement or agreement with
     respect to any parties other than the Underwriters for use in the
     Registration Statement or the Prospectus or any preliminary prospectus (or
     any amendment or supplement to them). When the Registration Statement
     becomes effective, including at the date of any post-effective amendment,
     at the date of the Prospectus and any amendment or supplement thereto (if
     different), at the Closing Date and at each Option Closing Date, as the
     case may be, the Indenture will have been qualified under and will conform
     in all material respects to the requirements of the Trust Indenture Act of
     1939, as amended, and the rules and regulations promulgated pursuant
     thereto (collectively, the "TIA").

          (c) Each preliminary prospectus filed as part of the registration
     statement as originally filed or as part of any amendment thereto, or filed
     pursuant to Rule 424 under the Act, complied when so filed in all material
     respects with the requirements of the Act; and did not contain an untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements therein, in the light
     of the circumstances under which they were made, not misleading.

          (d) The Company and each of its subsidiaries has been duly
     incorporated, is validly existing as a corporation in good standing under
     the laws of its jurisdiction of incorporation and has the corporate power

                                       11
<PAGE>
 
     and authority to carry on its business as it is currently being conducted
     and to own, lease and operate its properties, and each is duly qualified
     and is in good standing as a foreign corporation authorized to do business
     in each jurisdiction in which the nature of its business or its ownership
     or leasing of property requires such qualification, except where the
     failure to be so qualified would not have a material adverse effect on the
     condition, financial or otherwise, or the earnings, cash flow, business
     affairs or business prospects of the Company and its subsidiaries, taken as
     a whole (the foregoing exception herein defined as a "Material Adverse
     Effect").

          (e) All of the outstanding shares of capital stock of, or other
     ownership interests in, each of the Company's subsidiaries have been duly
     authorized and validly issued and are fully paid and nonassessable, and,
     except for the pledge to [THE FIRST NATIONAL BANK OF BOSTON AND FIRST
     INTERSTATE BANK OF CALIFORNIA, OTHERS?] (the "Banks") of capital stock of
     certain of the Company's subsidiaries [PURSUANT TO THE COMPANY'S CREDIT
     FACILITIES WITH THE BANKS (THE "CREDIT FACILITIES") -- DEFINE NEW CREDIT
     FACILITIES AS WILL BE DEFINED IN THE REGISTRATION STATEMENT], are owned by
     the Company (except as provided in the last sentence of this paragraph
     (e)), free and clear of any security interest, claim, lien, encumbrance or
     adverse interest of any nature.  The Company owns all of the outstanding
     capital stock of each of its subsidiaries, except with respect to
     subsidiaries that, when taken as a whole, do not account for a material
     proportion of the Company's business, operations or assets, and the loss of
     which would not result in a Material Adverse Effect upon the Company.

          (f) The Indenture has been duly authorized by the Company and, when
     duly executed and delivered in accordance with its terms (assuming the due
     execution and delivery thereof by the Trustee), will be a valid and legally
     binding agreement of the Company, enforceable against the Company in
     accordance with its terms, subject to applicable bankruptcy, insolvency,
     reorganization, moratorium, fraudulent transfer and similar laws affecting
     creditors' rights and remedies generally and to general principles of
     equity (regardless of whether enforcement is sought in a proceeding at law
     or in equity) and except to the extent that a waiver of rights under any
     usury laws may be unenforceable.

          (g) The Securities (including the Common Stock issuable upon
     conversion thereof) have been duly authorized by the Company and, on the

                                       12
<PAGE>
 
     Closing Date and the Option Closing Date, if any, the Securities will have
     been duly executed by the Company and will, when issued, executed,
     authenticated and delivered in accordance with the Indenture and paid for
     in accordance with the terms of this Agreement, constitute legal, valid and
     binding obligations of the Company, enforceable against the Company
     according to their terms, subject to applicable bankruptcy, insolvency,
     reorganization, moratorium, fraudulent transfer and similar laws affecting
     creditors' rights and remedies generally and to general principles of
     equity (regardless of whether enforcement is sought in a proceeding at law
     or in equity) and except to the extent that a waiver of rights under any
     usury laws may be unenforceable, will be entitled to the benefits of the
     Indenture and will conform in all material respects to the description
     thereof in the Prospectus.

          (h) All the issued and outstanding shares of capital stock of the
     Company have been duly authorized and validly issued and are fully paid,
     nonassessable and, except as otherwise set forth in the Prospectus, not
     subject to any preemptive or similar rights; the Shares have been duly
     authorized for issuance and sale to the Underwriters pursuant to this
     Agreement and, when issued and delivered by the Company pursuant to this
     Agreement against payment of the consideration set forth herein, will be
     validly issued, fully paid and nonassessable; and the issuance of the
     Shares by the Company will not be subject to preemptive or other similar
     rights.

          (i) The authorized capital stock of the Company, including the Common
     Stock, conforms to the description thereof contained in or incorporated by
     reference into the Prospectus.

          (j) Neither the Company nor any of its subsidiaries is in violation of
     its respective charter or by-laws or other equivalent instruments, as the
     case may be, or, except as such as would not have a Material Adverse
     Effect, in default in the performance of any obligation, agreement or
     condition contained in any bond, debenture, note or any other evidence of
     indebtedness or in any other agreement, lease, contract, indenture or
     instrument to which the Company or any of its subsidiaries is a party or by
     which it or any of its subsidiaries or their respective property is bound,
     and there exists no condition which, with the passage of time or otherwise,
     would constitute such a default under any such document or instrument.

                                       13
<PAGE>
 
          (k) The execution, delivery and performance of this Agreement, the
     Indenture and the Securities, compliance by the Company with all the
     provisions hereof and thereof and the consummation of the transactions
     contemplated hereby and thereby will not require any consent, approval,
     authorization or other order of any court, regulatory body, administrative
     agency or other governmental body (except as such may be required under the
     securities or Blue Sky laws of the various states) and will not conflict
     with or constitute a breach of any of the terms or provisions of, or a
     default (with the passage of time or otherwise) under, the charter or by-
     laws or other equivalent instruments, as the case may be, of the Company or
     any of its subsidiaries or, except such as would not have a Material
     Adverse Effect, any agreement, lease, contract, indenture or other
     instrument to which it or any of its subsidiaries is a party or by which it
     or any of its subsidiaries or their respective property is bound, or
     violate or conflict with any laws, administrative regulations or rulings or
     court decrees applicable to the Company, any of its subsidiaries or their
     respective property.

          (l) Except as would not result in a Material Adverse Effect, there are
     no legal or governmental proceedings pending to which the Company or any of
     its subsidiaries is a party or of which any of their respective property is
     subject, and, to the best of the Company's knowledge, no such proceedings
     are threatened or contemplated.  No contract or document of a character
     required to be described in the Registration Statement or the Prospectus or
     to be filed as an exhibit to the Registration Statement is not so described
     or filed as required.

          (m) Except as disclosed or incorporated by reference in the
     Prospectus, neither the Company nor any of its subsidiaries nor, to the
     best knowledge of the Company, any other person or entity for whom either
     is or may be liable is in violation of any Federal, state, local,
     provincial or foreign laws or regulations relating to pollution or
     protection of human health or the environment (including, without
     limitation, ambient air, surface water, ground water, land surface or
     subsurface strata), including, without limitation, laws and regulations
     relating to emissions, discharges, releases or threatened releases of
     chemicals, pollutants, contaminants, wastes, toxic substances, hazardous
     substances, petroleum or petroleum products, asbestos or asbestos-
     containing materials, or polychlorinated biphenyls ("Materials of
     Environmental Concern"), or otherwise relating to the manufacture,
     processing, distribution, use, treatment, storage, disposal, 

                                       14
<PAGE>
 
     transport or handling of Materials of Environmental Concern (collectively,
     "Environmental Laws"), which violation would have a Material Adverse Effect
     or would otherwise require disclosure in the Prospectus pursuant to Item
     103 of Regulation S-K under the Act ("Item 103"). "Violation" includes, but
     is not limited to, noncompliance with any permit or other governmental
     authorization required under applicable Environmental Laws and
     noncompliance with the terms and conditions of any such permit or
     authorization.

          (n) Except as disclosed or incorporated by reference in the
     Prospectus, neither the Company nor any of its subsidiaries has received
     any communication (written or, to the knowledge of the Company or any of
     its subsidiaries, oral), whether from a governmental authority, citizens'
     group, employee or otherwise, asserting that the Company or any of its
     subsidiaries or any other person or entity for whom either is or may be
     liable is not in compliance with any Environmental Laws or permit or
     authorization required under applicable Environmental Laws where such
     failure to comply would have a Material Adverse Effect or would otherwise
     require disclosure in the Prospectus pursuant to Item 103, and there are no
     circumstances that may prevent or interfere with such full compliance in
     the future, except where failure so to comply would not have a Material
     Adverse Effect.

          (o) Except as disclosed or incorporated by reference in the
     Prospectus, there is no claim, action, cause of action, investigation or
     notice (written or oral) by any person or entity alleging potential
     liability (including, without limitation, potential liability for
     investigatory costs, natural resources damages, property damages, personal
     injuries or penalties) arising out of, based on or resulting from (i) the
     presence in or release into the environment of any Materials of
     Environmental Concern at any location owned, leased or operated, now or in
     the past, by the Company or any of its subsidiaries or, to the best
     knowledge of the Company, any other person or entity for whom either is or
     may be liable, or (ii) circumstances forming the basis of any violation or
     alleged violation of any Environmental Law (collectively, "Environmental
     Claims") pending or threatened against the Company or any of its
     subsidiaries or, to the best knowledge of the Company, any other person or
     entity whose liability for any Environmental Claim the Company or any of
     its subsidiaries has retained or assumed either contractually or by
     operation of law, except any such matter that would not 

                                       15
<PAGE>
 
     have a Material Adverse Effect or would not otherwise require disclosure in
     the Prospectus pursuant to Item 103.
 
          (p) Except as disclosed or incorporated by reference in the
     Prospectus, there are no past or present actions, activities,
     circumstances, conditions, events or incidents, including, without
     limitation, the release, emission, discharge, presence or disposal of any
     Materials of Environmental Concern, that could form the basis of any
     Environmental Claim against the Company or any of its subsidiaries with
     respect to property owned, leased or operated by or for the Company or any
     of its subsidiaries, now or in the past, or, to the best knowledge of the
     Company, against any person or entity whose liability for any Environmental
     Claim the Company or any of its subsidiaries has retained or assumed either
     contractually or by operation of law, except any such matter that would not
     have a Material Adverse Effect or would not otherwise require disclosure in
     the Prospectus pursuant to Item 103.

          (q) In the ordinary course of its business, the Company addresses its
     environmental compliance obligations with respect to the business,
     operations and properties of the Company and its subsidiaries, in the
     course of which it identifies and evaluates, as appropriate, associated
     costs and liabilities.  On the basis of such procedures, except for costs
     and liabilities heretofore incurred and reflected in the Company's
     financial statements as set forth or incorporated by reference in the
     Registration Statement, the Company has reasonably concluded that such
     associated costs and liabilities would not, singly or in the aggregate,
     have a Material Adverse Effect.

          (r) Except as otherwise set forth or incorporated by reference in the
     Prospectus or such as would not, singly or in the aggregate, have a
     Material Adverse Effect, the Company and each of its subsidiaries has good
     and marketable title, free and clear of all liens, claims, encumbrances and
     restrictions, except liens for taxes not yet due and payable and
     restrictions on the Company's ability to encumber its assets contained in
     its [CREDIT FACILITIES] with the Banks, to all property and assets
     described in the Registration Statement as being owned by it.  All leases
     to which the Company or any of its subsidiaries is a party are valid and
     binding and, except as would not have a Material Adverse Effect, no default
     has occurred or is continuing thereunder; and the Company and its
     subsidiaries enjoy peaceful 

                                       16
<PAGE>
 
     and undisturbed possession under all such leases to which any of them is a
     party as lessee.

          (s) The Company and each of its subsidiaries maintains insurance in
     amounts and with limits and coverage which the Company in good faith deems
     appropriate.

          (t) Each of the accountants who certified the financial statements and
     supporting schedules included in the Registration Statement is an
     independent public accountant as required by the Act.

          (u) The financial statements, together with related schedules and
     notes, as set forth or incorporated by reference in the Registration
     Statement and the Prospectus (and any amendment or supplement thereto),
     present fairly the consolidated financial position, results of operations
     and changes in financial position of the Company and its subsidiaries at
     the respective dates or for the respective periods to which they apply;
     such statements and related schedules and notes have been prepared in
     accordance with generally accepted accounting principles consistently
     applied throughout the periods involved, except as disclosed therein; and
     the other financial and statistical information and data set forth in the
     Registration Statement and the Prospectus (and any amendment or supplement
     thereto) is, in all material respects, fairly presented and prepared on a
     basis consistent with such financial statements and the books and records
     of the Company.  The pro forma financial information included in the
                          --- -----                                      
     Prospectus presents fairly the information shown therein and has been
     prepared in accordance with the relevant accounting requirements of
     Regulation S-X.  In the opinion of the Company, the assumptions used in the
     preparation of the pro forma financial information are reasonable and the
     adjustments used therein are appropriate to give effect to the transactions
     or circumstances referred to therein.

          (v) Except as would not result in a Material Adverse Effect, (i) the
     Company and each of its subsidiaries has such permits, licenses, franchises
     and authorizations of governmental or regulatory authorities ("permits") as
     are necessary to own, lease and operate its respective properties and to
     conduct its business in the manner described or incorporated by reference
     in the Prospectus, subject to such qualifications as may be set forth or
     incorporated by reference in the Prospectus; (ii) the Company and 

                                       17
<PAGE>
 
     each of its subsidiaries has fulfilled and performed all of its obligations
     with respect to such permits and no event has occurred which allows, or
     after notice or lapse of time or both would allow, revocation or
     termination thereof or results in any other impairment of the rights of the
     holder of any such permit, subject in each case to such qualification as
     may be set forth or incorporated by reference in the Prospectus; and (iii)
     except as described or incorporated by reference in the Prospectus, such
     permits contain no restrictions that are burdensome to the Company or any
     of its subsidiaries.

          (w) The Company is not an "investment company" or a company
     "controlled" by an "investment company" within the meaning of the
     Investment Company Act of 1940, as amended.

          (x) Except rights as to which waivers have been obtained in writing
     with respect to inclusion in this offering, no holder of any security of
     the Company other than the Selling Stockholders (as that term is defined in
     the prospectus relating to the Common Stock Offering), [AND _____] has any
     right to require registration of shares of Common Stock or any other
     security of the Company.

          (y) The Company has complied with all provisions of Section 517.075,
     Florida Statutes (Chapter 92-198, Laws of Florida).

          (z) There are no outstanding subscriptions, rights, warrants, options,
     calls, convertible securities, commitments of sale or liens related to or
     entitling any person to purchase or otherwise to acquire any shares of the
     capital stock of, or other ownership interest in, the Company or any
     subsidiary thereof except as otherwise disclosed or incorporated by
     reference in the Registration Statement or which have been granted pursuant
     to the Company's stock option plans in amounts which are immaterial or are
     required by law.

          (aa) Except as would not, singly or in the aggregate, have a Material
     Adverse Effect, neither the Company nor any of its subsidiaries has (A)
     violated any applicable federal, state, provincial or foreign law relating
     to employment or employment practices or the terms and conditions of
     employment, including, without limitation, discrimination in the hiring,
     promotion or pay of employees, wages, hours of work, plant closings and
     layoffs, collective bargaining, and occupational safety and 


                                      18
<PAGE>
 
     health, or any provisions of the Employee Retirement Income Security Act of
     1974 ("ERISA") or the rules and regulations promulgated thereunder or any
     other applicable law (whether foreign or domestic) relating to or governing
     the operation or maintenance of any plan or arrangement falling within the
     definition of an "employee benefit plan" (as such term is defined in
     Section 3(3) of ERISA) or any other employee benefit plan or arrangement,
     or (B) engaged in any unfair labor practice. Except as would not, singly or
     in the aggregate, result in any Material Adverse Effect, there is (i) no
     unfair labor practice charge or complaint pending or threatened against the
     Company or any of its subsidiaries before the National Labor Relations
     Board or any corresponding state, local, provincial or foreign agency, and
     no grievance or arbitration proceeding arising out of or under any
     collective bargaining agreement is so pending or threatened against the
     Company or any of its subsidiaries; and (ii) no union representation claim
     or question existing with respect to the employees of the Company or any of
     its subsidiaries and no union organizing activities taking place. Except as
     would not, singly or in the aggregate, result in any Material Adverse
     Effect, (i) no labor dispute involving the employees of the Company or any
     of its subsidiaries exists or, to the knowledge of the Company, is
     threatened or imminent; and (ii) the Company is not aware of any existing,
     threatened or imminent labor disturbance by the employees of any principal
     suppliers, manufacturers or contractors of the Company or any of its
     subsidiaries.

          (bb) The books, records and accounts of the Company and its
     subsidiaries accurately and fairly reflect, in reasonable detail, the
     transactions in and dispositions of the assets of the Company and its
     subsidiaries.  The Company and each of its subsidiaries maintains a system
     of internal accounting controls sufficient to provide reasonable assurance
     that (i) transactions are executed in accordance with management's general
     or specific authorizations; (ii) transactions are recorded as necessary to
     permit preparation of financial statements in conformity with generally
     accepted accounting principles and to maintain asset accountability; (iii)
     access to assets is permitted only in accordance with management's general
     or specific authorization; and (iv) the recorded accountability for assets
     is compared with the existing assets at reasonable intervals and
     appropriate action is taken with respect to any differences.

          (cc) All material tax returns required to be filed by the Company and
     each of its subsidiaries in any jurisdiction have been filed, other than

                                       19
<PAGE>
 
     those filings being contested in good faith, and all material taxes,
     including withholding taxes, penalties and interest, assessments, fees and
     other charges due pursuant to such returns or pursuant to any assessment
     received by the Company or any of its subsidiaries have been paid, other
     than those being contested in good faith and for which adequate reserves
     have been provided.  No deficiency or adjustment for any material taxes
     has been proposed or assessed against the Company or any of its
     subsidiaries.

          (dd) The Company and its subsidiaries own, license or possess the
     patents, patent rights, licenses, inventions, copyrights, know-how
     (including trade secrets and other unpatented and/or unpatentable
     proprietary or confidential information, systems or procedures),
     trademarks, service marks and trade names presently employed by them in
     connection with the businesses now operated by them, except such as to
     which the failure so to own, license or possess would not, singly or in the
     aggregate, have a Material Adverse Effect, and neither the Company nor any
     of its subsidiaries has received any notice of infringement of or conflict
     with asserted rights of others with respect to any of the foregoing, which,
     singly or in the aggregate, if the subject of any unfavorable decision,
     ruling or finding, would result in a Material Adverse Effect.

          (ee) Each of the Company and its subsidiaries is in compliance with
     all laws, ordinances and regulations (domestic and foreign) applicable to
     its properties (whether owned or leased) and its business, as described in
     the Prospectus, except where noncompliance with such laws, ordinances and
     regulations would not, singly or in the aggregate, have a Material Adverse
     Effect.

          7. Indemnification.
             --------------- 

          (a) The Company agrees to indemnify and hold harmless (i) each of the
     Underwriters and (ii) each person, if any, who controls (within the meaning
     of Section 15 of the Act or Section 20 of the Exchange Act) any of the
     Underwriters (any of the persons referred to in this clause (ii) being
     hereinafter referred to as a "controlling person"), and (iii) the
     respective officers, directors, partners, employees, representatives and
     agents of any of the Underwriters or any controlling person (any person
     referred to in clause (i), (ii) or (iii) may hereinafter be referred to as
     an "Indemnified Person") to the fullest extent lawful, from and against any
     and all losses, 

                                       20
<PAGE>
 
     claims, damages, liabilities, judgments, actions and expenses (including
     without limitation and as incurred, reimbursement of all reasonable costs
     of investigating, preparing, pursuing or defending any claim or action, or
     any investigation or proceeding by any governmental agency or body,
     commenced or threatened, including the reasonable fees and expenses of
     counsel to any Indemnified Person) directly or indirectly caused by,
     related to, based upon, arising out of or in connection with any untrue
     statement or alleged untrue statement of a material fact contained in the
     Registration Statement (or any amendment thereto), including the
     information deemed to be a part of the Registration Statement pursuant to
     Rule 430A promulgated under the Act, if applicable, or the Prospectus
     (including any amendment or supplement thereto) or any preliminary
     prospectus, or any omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein (in the case of the Prospectus, in light of the circumstances under
     which they were made) not misleading, except insofar as such losses,
     claims, damages, liabilities or expenses are caused by an untrue statement
     or omission or alleged untrue statement or omission that is (i) made in
     reliance upon and in conformity with information relating to any
     Underwriter Information or (ii) with respect to the Underwriter from whom
     the person asserting the loss, claim, damage or liability purchased
     Securities, made in any preliminary prospectus if a copy of the Prospectus
     (as amended or supplemented) shall have been furnished to the Underwriters
     by the Company with such amendments or supplements thereto on a timely
     basis and such Prospectus was not delivered by or on behalf of any of the
     Underwriters to the person asserting the claim or action, if required by
     law to have been so delivered by the Underwriter seeking indemnification,
     at or prior to the written confirmation of the sale of the Securities, and
     it shall be finally determined by a court of competent jurisdiction, by a
     judgment not subject to appeal or review, that the Prospectus (as so
     amended or supplemented) would have corrected such untrue statement or
     omission. The Company shall notify you promptly of the institution, threat
     or assertion of any claim, proceeding (including any governmental
     investigation) or litigation in connection with the matters addressed by
     this Agreement which involves the Company or an Indemnified Person.

          (b) In case any action or proceeding (including any governmental
     investigation) shall be brought or asserted against any Indemnified Person
     with respect to which indemnity may be sought against an indem-

                                       21
<PAGE>
 
     nifying party (or indemnifying parties), such Indemnified Person shall
     promptly notify the indemnifying party (or indemnifying parties) in writing
     (provided that the failure to give such notice shall not relieve the
      --------
     indemnifying party (or indemnifying parties) of its obligations pursuant to
     this Agreement unless and only to the extent such failure to give notice
     results in the loss or compromise of any material rights or defenses of the
     indemnifying party (or indemnifying parties) as determined by a court of
     competent jurisdiction by a final judgment no longer subject to appeal or
     review). Upon receiving such notice, the indemnifying party (or
     indemnifying parties) shall be entitled to participate in any such action
     or proceeding and to assume, at their sole expense, the defense thereof,
     with counsel satisfactory to such Indemnified Person (who shall not, except
     with the consent of the Indemnified Person, be counsel to the indemnifying
     party (or indemnifying parties) or an affiliate thereof) and, after written
     notice from the indemnifying party (or indemnifying parties) to such
     Indemnified Person of their election so to assume the defense thereof
     within 5 business days after receipt of the notice from the Indemnified
     Person of such action or proceeding, the indemnifying party (or
     indemnifying parties) shall not be liable to such Indemnified Person
     hereunder for legal expenses of other counsel subsequently incurred by such
     Indemnified Person in connection with the defense thereof, other than
     reasonable costs of investigation, unless (i) the indemnifying party (or
     indemnifying parties) agrees in writing to pay such fees and expenses, or
     (ii) the indemnifying party (or indemnifying parties) fails to assume such
     defense within the 5 business days specified above or fails to employ
     counsel satisfactory to such Indemnified Person, or (iii) the named parties
     to any such action or proceeding (including any impleaded parties) include
     both such Indemnified Person and the indemnifying party (or indemnifying
     parties) or its affiliates, and such Indemnified Person shall have been
     advised by counsel either (x) that there may be one or more legal defenses
     available to such Indemnified Person that are different from or additional
     to those available to the indemnifying party (or indemnifying parties), or
     (y) a conflict of interest exists between such Indemnified Person and the
     indemnifying party (or indemnifying parties) or its affiliates (in which
     case, if such Indemnified Person notifies the indemnifying party (or
     indemnifying parties) in writing, neither the indemnifying party (or
     indemnifying parties) shall have the right to assume the defense thereof),
     it being understood, however, that the indemnifying party (or indemnifying
     parties) shall not, in connection with any one such action or proceeding or
     separate but substantially similar or related actions

                                       22
<PAGE>
 
     or proceedings in the same jurisdiction arising out of the same general
     allegations or circumstances, be liable for the reasonable fees and
     expenses of more than one separate firm of attorneys (in addition to any
     local counsel) at any time for such Indemnified Persons, which firm shall
     be designated in writing by DLJ. No indemnifying party shall be liable for
     any settlement of any such action or proceeding effected without its prior
     written consent. Notwithstanding the foregoing sentence, if at any time an
     Indemnified Person shall have requested the indemnifying party (or
     indemnifying parties) to reimburse the Indemnified Person for fees and
     expenses of counsel as contemplated by the second sentence of this
     paragraph, the indemnifying party (or indemnifying parties) agree that they
     shall be liable for any settlement of any proceeding effected without its
     written consent if (i) such settlement is entered into more than 45
     business days after receipt by the indemnifying party (or indemnifying
     parties) of the aforesaid request and (ii) the indemnifying party (or
     indemnifying parties) shall not have reimbursed the Indemnified Person in
     accordance with such request prior to the date of such settlement. Neither
     the indemnifying party (or indemnifying parties) shall, without the prior
     written consent of each Indemnified Person, settle or compromise or consent
     to the entry of judgment in or otherwise seek to terminate any pending or
     threatened action, claim, litigation or proceeding in respect of which
     indemnification or contribution may be sought hereunder (whether or not any
     Indemnified Person is a party thereto), unless such settlement, compromise,
     consent or termination includes an unconditional release of each
     Indemnified Person from all liability arising out of such action, claim,
     litigation or proceeding.

          (c) Each of the Underwriters agrees, severally and not jointly, to
     indemnify and hold harmless the Company, its directors, its officers who
     sign the Registration Statement, and any person controlling (within the
     meaning of Section 15 of the Act or Section 20 of the Exchange Act) any of
     the Company, to the same extent as the foregoing indemnity from the Company
     to each of the Indemnified Persons, but only with respect to claims and
     actions based on any Underwriter Information.

          (d) If the indemnification provided for in this Section 7 is
     unavailable to an indemnified party in respect of any losses, claims,
     damages, liabilities or expenses referred to herein, then each of the
     Company and the Underwriters, as applicable, in lieu of indemnifying such
     indemnified party, shall contribute to the amount paid or payable by such
     indem-

                                       23
<PAGE>
 
     nified party as a result of such losses, claims, damages, liabilities and
     expenses (i) in such proportion as is appropriate to reflect the relative
     benefits received by the Company on the one hand and the Indemnified
     Persons on the other hand from the offering of the Securities or (ii) if
     the allocation provided by clause (i) above is not permitted by applicable
     law, in such proportion as is appropriate to reflect not only the relative
     benefits referred to in clause (i) above but also the relative fault of the
     indemnifying parties and the indemnified party, as well as any other
     relevant equitable considerations. The relative benefits received by the
     Company, on the one hand, and any of the Underwriters, on the other hand,
     shall be deemed to be in the same proportion as the total proceeds from the
     offering (net of underwriting discounts and commissions but before
     deducting expenses) received by the Company bear to the total underwriting
     discounts and commissions received by such Underwriter, in each case as set
     forth in the table on the cover page of the Prospectus. The relative fault
     of the Company and, on the one hand, and the Underwriters, on the other
     hand, shall be determined by reference to, among other things, whether the
     untrue or alleged untrue statement of a material fact or the omission or
     alleged omission to state a material fact related to information supplied
     by the Company, on the one hand, or the Underwriters, on the other hand,
     and the parties' relative intent, knowledge, access to information and
     opportunity to correct or prevent such statement or omission. The indemnity
     and contribution obligations of the Company set forth herein shall be in
     addition to any liability or obligation that the Company may otherwise have
     (other than with respect to the matters covered by this Section 7) to any
     Indemnified Person.

          The Company and the Underwriters agree that it would not be just and
     equitable if contribution pursuant to this Section 7(d) were determined by
     pro rata allocation (even if the Underwriters were treated as one entity
     --- ----                                                                
     for such purpose) or by any other method of allocation that does not take
     account of the equitable considerations referred to in the immediately
     preceding paragraph.  The amount paid or payable by an indemnified party as
     a result of the losses, claims, damages, liabilities or expenses referred
     to in the immediately preceding paragraph shall be deemed to include,
     subject to the limitations set forth above, any legal or other expenses
     reasonably incurred by such indemnified party in connection with
     investigating or defending any such action or claim.  Notwithstanding the
     provisions of this Section 7, none of the Underwriters (and its related
     Indemnified Persons) 

                                       24
<PAGE>
 
     shall be required to contribute, in the aggregate, any amount in excess of
     the amount by which the total underwriting discount applicable to the
     Securities purchased by such Underwriter exceeds the amount of any damages
     which such Underwriter has otherwise been required to pay by reason of such
     untrue or alleged untrue statement or omission or alleged omission. No
     person guilty of fraudulent misrepresentation (within the meaning of
     Section 11(f) of the Act) shall be entitled to contribution from any person
     who was not guilty of such fraudulent misrepresentation. The Underwriters'
     obligations to contribute pursuant to this Section 8(d) are several in
     proportion to the respective number of Securities purchased by each of the
     Underwriters hereunder and not joint.

          (e) The rights and obligations provided in this Section 7 shall
     terminate seven years from the date hereof.

          8.   Conditions of Underwriters' Obligations.  The several obligations
               ---------------------------------------

     Date no stop order suspending the effectiveness of the Registration
     Statement shall have been issued and no proceedings for that purpose shall
     have been commenced or shall be pending before or contemplated by the
     Commission.

          (c) No action shall have been taken and no statute, rule or regulation

     agency which would, as of the Closing Date, prevent the issuance of the
     Securities; no injunction, restraining order or order of any nature by a
     U.S. federal or state court of competent jurisdiction shall have been
     issued as of the Closing Date which would prevent the issuance of the
     Securities; except as disclosed in the Prospectus, on the Closing Date, no
     action, suit or proceeding shall be pending against, or, to the knowledge
     of 

                                       25
<PAGE>
 
     the Company, threatened against, the Company or any of its subsidiaries,
     respectively, before any court or arbitrator or any governmental body,
     agency or official which, if adversely determined, would interfere with or
     adversely affect the issuance of the Securities or could reasonably be
     expected to have a Material Adverse Effect, or in any manner invalidate
     this Agreement or the sale of the Securities. Subsequent to the execution
     and delivery of this Agreement and prior to the Closing Date, and each
     Option Closing Date, if applicable, there shall not have been any
     downgrading, nor shall any notice have been given of any intended or
     potential downgrading or of any review for a possible change that does not
     indicate the direction of the possible change, in the rating accorded any
     of the Company's securities by any "nationally recognized statistical
     rating organization," as such term is defined for purposes of Rule
     436(g)(2) of the Act.

          (d) (i) Since the date of the latest balance sheet included in or
     incorporated by reference into the Registration Statement and the

     condition, financial or otherwise, or in the earnings, cash flows, business
     affairs or business prospects, whether or not arising in the ordinary
     course of business, of the Company and its subsidiaries, taken as a whole,
     (ii) except as set forth in the Registration Statement, since the date of
     the latest balance sheet included in or incorporated by reference into the
     Registration Statement and the Prospectus, there shall not have been any
     material adverse change, or any development involving a prospective
     material adverse change, in the capital stock or in the long-term debt, or
     material increase in short-term debt, of the Company and its subsidiaries,
     taken as a whole, (iii) the Company and its subsidiaries shall have no
     liability or obligation, direct or contingent, which is material to the
     Company and its subsidiaries, taken as a whole, other than those reflected
     or incorporated by reference in the Registration Statement and the
     Prospectus and (iv) on the Closing Date you shall have received a
     certificate dated the Closing Date, signed by Richard J. Heckmann and Kevin
     L. Spence, in their capacities as the Chief Executive Officer and the Chief
     Financial Officer of the Company, respectively, confirming the matters
     expressly relating to the Company set forth in paragraphs (a), (b), (c)
     (with respect to the first two clauses of such paragraph (c), to the
     Company's best knowledge) and (d) of this Section 8.

          of any security interest, claim, lien, encumbrance or adverse interest
          of any nature;

               (vii)  the Registration Statement and the Prospectus comply as to
          form in all material respects with the requirements for registration
          statements on Form S-3 under the Act, the TIA and the rules and

          financial statements, schedules and other financial and statistical
          data included in the Registration Statement or the Prospectus or with
          respect to the Form T-1;

               (viii) the Indenture, assuming due authorization, execution and

          remedies of creditors; general principles of equity (regardless of
          whether enforcement is considered in a proceeding in equity or law),
          and the discretion of the court before which any proceeding therefor
          may be brought; the unenforceability under certain circumstances under
          law or court decisions of provisions providing for the indemnification
          of or contribution to a party with respect to a liability where such
          indemnification or contribution is contrary to public policy; the
          enforceability of the waiver of rights or defenses contained in

<PAGE>
 
               (xi)   the Registration Statement has become effective under the
          Act, and, to such counsel's knowledge, no stop order suspending its
          effectiveness has been issued and no proceedings for that purpose are

          II of the Registration Statement, insofar as such statements
          constitute a summary of legal matters or certain contents of documents
          referred to therein, are fair summaries of such legal matters or
          contents of documents;

               (xiii) the execution, delivery and performance of this Agreement
          by the Company, compliance by the Company with all the provisions
          hereof and the consummation of the transactions contemplated hereby
          will not require any consent, approval, authorization or other order
          of any court, regulatory body, administrative agency or other
          governmental body (except as such may be required under the Act or
          other securities or Blue Sky laws) and, except as would not have a
          Material Adverse Effect, will not violate or constitute a breach of
          any of the terms or provisions of, or a default (with the passage of
          time, the giving of notice or otherwise) under, the charter or by-laws
          or other equivalent instruments, as the case may be, of the Company or
          any of the Subsidiaries or any agreement, lease, contract, indenture
          or other instrument that is an exhibit to the Registration Statement
          or any document incorporated by reference therein, or (assuming
          compliance with all applicable state securities or Blue Sky laws)
          violate any laws or administrative regulations applicable to the
          Company or any of its Subsidiaries or their respective properties
          which, in such counsel's opinion, are normally applicable to the
          transactions of the type contemplated by this Agreement or violate any
          judgment, injunction, order or decree known to such counsel that names
          the Company or any of the Subsidiaries and is specifically directed to
          any of them or any of their respective properties;

               (xiv)  such counsel does not know of any contract or other
          document to which the Company or any Subsidiary is a party which 

                                       29
<PAGE>
 
          is required to be described in the Registration Statement or the

          Registration Statement which is not described or filed as required;

               (xv)    the Company has the corporate power and authority to
          enter into and perform this Agreement; and this Agreement has been
          duly authorized, executed and delivered by the Company and is a valid

          its terms (except as rights to indemnity and contribution hereunder
          may be limited by applicable law);

               (xvi)   to the best of such counsel's knowledge, except for
          rights as to which waivers have been obtained in writing with respect
          to inclusion in this Offering, no holder of any security of the
          Company has any right to require registration of any security of the
          Company other than [ ];

               (xvii)  the Registration Statement and the Prospectus and any
          supplement or amendment thereto (except for financial statements and
          financial schedules and other statistical data included or
          incorporated therein as to which no opinion need be expressed) comply
          as to form in all material respects with the Act; and

               (xviii) the Company is not an "investment company" or a company
          "controlled" by an "investment company" within the meaning of the
          Investment Company Act of 1940, as amended.


          In addition, such counsel shall state that such counsel has
participated in conferences with officers and other representatives of the
Company, representatives of the independent public accountants of each of the
Company[, WATERPRO SUPPLIES CORPORATION, WHEELABRATOR TECHNOLOGIES INC.--SYSTEMS
AND MANUFACTURING GROUP, UNITED UTILITIES PLC--PROCESS DIVISION AND THE UTILITY
SUPPLY GROUP, INC.,] and representatives of the Underwriters and their counsel
at which the contents of the Registration Statement and the Prospectus were
discussed and, although such counsel has not independently verified and is not
passing upon and does not assume responsibility for the accuracy, completeness
or fairness of the statements contained in the Registration Statement or the
Prospectus (except as specified elsewhere in such counsel's opinion), on the
basis of the foregoing, 

                                       30
<PAGE>
 
nothing has come to the attention of such counsel that causes such counsel to
believe that the Registration Statement, at the time such Registration Statement
or any post-effective amendment became effective, contained any untrue statement
of a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, or that the
Prospectus, as amended or supplemented, as of its date and the Closing Date,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading (it
being understood that such counsel need express no opinion with respect to the
financial statements, schedules, statistical data, and pro forma and other
financial data included in the Registration Statement or the Prospectus).

          The opinion of Kirkpatrick & Lockhart LLP described in paragraph (e)
above shall be rendered to you at the request of the Company and shall so state
therein. In rendering such opinions, such counsel may rely upon certificates of
any officer of the Company or of government officials as to matters of fact of
which the maker of such certificate has knowledge provided that counsel
rendering such opinion shall furnish the Underwriters with copies of any such
statements or certificates. In addition, in rendering their opinion, such
counsel may state that their opinion is limited to matters of the laws of the
Commonwealth of Pennsylvania, the General Corporation Law of the State of
Delaware and U.S. Federal law.

          (f)  You shall have received on the Closing Date an opinion
     (satisfactory to you and counsel for the Underwriters), dated the Closing
     Date, of Damian C. Georgino, General Counsel for the Company, to the effect
     that:

               (i) to the knowledge of such counsel, each contract or document
          described in or whose description is incorporated into the Prospectus
          is, unless otherwise disclosed therein, in full force and effect in
          accordance with its terms, except as would not cause a Material
          Adverse Effect;

               (ii) neither the Company nor any of its subsidiaries is in
          violation of its respective charter or by-laws or other equivalent

          knowledge, except as would not have a Material Adverse Effect, neither
          the Company nor any of its subsidiaries is in default in the
          performance of any obligation, agreement or condition contained in any
          bond, debenture, note or any other evidence of indebtedness or in any
          other agreement, lease, contract, indenture or instrument to which the
          Company or any of its subsidiaries is a party or by which it or any of
          its subsidiaries or their respective property is bound, and there
          exists no condition which, with the passage of time or otherwise,
          would constitute such a default under any such document or instrument;

               (iii)  the execution, delivery and performance of this Agreement,
          the Indenture and the Securities by the Company, compliance by the
          Company with all the provisions hereof and thereof and the
          consummation of the transactions contemplated hereby and thereby will
          not require any consent, approval, authorization or other order of any
          court, regulatory body, administrative agency or other governmental
          body (except as such may be required under the Act or other securities
          or Blue Sky laws) and will not conflict with or constitute a breach of
          any of the terms or provisions of, or a default (with the passage of
          time or otherwise) under, the charter or by-laws or other equivalent
          instruments, as the case may be, of the Company or any of its
          subsidiaries or, except as such would not have a Material Adverse
          Effect, any agreement, lease, contract, indenture or other instrument
          to which the Company or any of its subsidiaries is a party or by which
          the Company or any of its subsidiaries or their respective properties
          are bound, or, except such as would not have a Material Adverse
          Effect, violate or conflict with any valid statutes or valid and
          published administrative regulations applicable to the Company or any
          of its subsidiaries or their respective properties which, in such
          counsel's opinion, are normally applicable to the transactions of the
          type contemplated by this Agreement or violate any judgment,
          injunction, order or decree known to such counsel that names the
          Company or any of the Subsidiaries and is specifically directed to any
          of them or any of their respective properties;

               (iv) such counsel does not know of any legal or governmental
          proceeding pending or threatened to which the Company or

          any of its subsidiaries is a party or to which any of their respective
          property is subject which is required to be described in the
          Registration Statement or the Prospectus and is not so described or
          incorporated by reference;

               (v) the Company has the corporate power and authority to enter
          into and perform this Agreement, the Indenture and the Securities;
          this Agreement, the Indenture and the Securities has been duly
          authorized, executed and delivered by the Company and is a valid and
          binding agreement of the Company enforceable in accordance with its
          terms (except as rights to indemnity and contribution hereunder may be
          limited by applicable law).

          In addition, such counsel shall state that such counsel has
participated in conferences with officers and other representatives of the
Company and the Selling Stockholder, representatives of the independent public
accountants of each of the Company[, WATERPRO SUPPLIES CORPORATION, WHEELABRATOR
TECHNOLOGIES INC.--SYSTEMS AND MANUFACTURING GROUP, UNITED UTILITIES PLC--
PROCESS DIVISION AND THE UTILITY SUPPLY GROUP, INC.,] and representatives of the
Underwriters and their counsel at which the contents of the Registration
Statement and the Prospectus were discussed and, although such counsel has not
independently verified and is not passing upon and does not assume
responsibility for the accuracy, completeness or fairness of the statements
contained in the Registration Statement or the Prospectus (except as specified
elsewhere in such counsel's opinion), on the basis of the foregoing, nothing has
come to the attention of such counsel that causes such counsel to believe that
the Registration Statement, at the time such Registration Statement or any post-
effective amendment became effective, contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading, or that the
Prospectus, as amended or supplemented, as of its date and the Closing Date,
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading (it
being understood that such counsel need express no opinion with respect to the
financial statements, schedules, statistical data, and pro forma and other
financial data included in the Registration Statement or the Prospectus).

               -------------------------------------------                 
shall become effective upon the execution of this Agreement.

by you by written notice to the Company if any of the following has occurred:
(i) since the respective dates as of which information is given in the
Registration Statement and the Prospectus, any adverse change or development
involving a prospective adverse change in the condition, financial or otherwise,
of the Company or any of its subsidiaries or the earnings, cash flows, business
affairs, or business prospects of the Company or any of its subsidiaries,

enforce contracts for the sale of the Securities, (ii) any outbreak or
escalation of hostilities or other national or international calamity or crisis
or change in economic conditions or in the financial markets of the United
States or elsewhere that, in your judgment, is material and adverse and would,

either federal or New York State authorities or (vi) the taking of any action by
any federal, state or local government or agency in respect of its monetary or
fiscal affairs which in your judgment has a material adverse effect on the
financial markets in the United States and would, in your judgment, make it
impracticable or inadvisable to market the Securities or to enforce contracts
for the sale of the Securities

          If on the Closing Date any one or more of the Underwriters shall fail
or refuse to purchase the Firm Securities which it or they have agreed to
purchase hereunder on such date and the aggregate number of Firm Securities
which such defaulting Underwriter or Underwriters, as the case may be, agreed
but failed or refused to purchase is not more than one-tenth of the total number
of Securities to be purchased on such date by all Underwriters, each non-
defaulting Underwriter shall be obligated severally, in the proportion which the
number of Firm Securities 

                                      35
<PAGE>
 
set forth opposite its name in Schedule I bears to the total number of Firm
Securities which all the non-defaulting Underwriters, as the case may be, have
agreed to purchase, or in such other proportion as you may specify, to purchase
the Firm Securities which such defaulting Underwriter or Underwriters, as the
case may be, agreed but failed or refused to purchase on such date; provided
that in no event shall the number of Firm Securities which any Underwriter has
agreed to purchase pursuant to Section 3 hereof be increased pursuant to this
Section 9 by an amount in excess of one-ninth of such number of Firm Securities
without the written consent of such Underwriter. If on the Closing Date any
Underwriter or Underwriters shall fail or refuse to purchase Firm Securities and
the aggregate number of Firm Securities with respect to which such default
occurs is more than one-tenth of the aggregate number of Shares to be purchased
on such date by all Underwriters, and arrangements satisfactory to you and the
Company for purchase of such Securities are not made within 48 hours after such
default, this Agreement will terminate without liability on the part of any non-
defaulting Underwriter and the Company. In any such case which does not result
in termination of this Agreement, either you or the Company shall have the right
to postpone the Closing Date, but in no event for longer than seven days, in
order that the required changes, if any, in the Registration Statement and the
Prospectus or any other documents or arrangements may be effected. Any action
taken under this paragraph shall not relieve any defaulting Underwriter from
liability in respect of any default of any such Underwriter under this
Agreement.

               -------------

contribution agreements of the Company and its officers and directors and of the
several Underwriters set forth in this Agreement shall remain operative and in
full force and effect, and will survive delivery of and payment for the
Securities for a period of seven years, regardless of (i) any investigation, or
statement as to the 

                                       36
<PAGE>
 
results thereof, made by or on behalf of any Underwriter or by or on behalf of
the Company, its officers or directors, or any controlling person of the Company
(ii) acceptance of the Securities and payment for them hereunder and (iii)

fulfill any of the conditions of this Agreement, the party whose failure or
refusal to comply with such terms or fulfill such conditions shall reimburse the
several Underwriters for all out-of-pocket expenses (including the fees and

PERFORMED ENTIRELY WITHIN THE STATE OF NEW YORK, EXCLUDING (TO THE GREATEST
EXTENT PERMISSIBLE BY LAW) ANY RULE OF LAW THAT WOULD CAUSE THE APPLICATION OF

BEHALF OF ITSELF AND ITS SUBSIDIARIES, HEREBY IRREVOCABLY SUBMITS TO THE
EXCLUSIVE JURISDICTION OF ANY NEW YORK STATE COURT SITTING IN THE BOROUGH OF

RELATED TO THIS AGREEMENT OR ANY OF THE MATTERS CONTEMPLATED HEREBY IRREVOCABLY
WAIVES ANY DEFENSE OF LACK OF PERSONAL JURISDICTION AND IRREVOCABLY AGREES THAT
ALL CLAIMS IN RESPECT OF ANY SUIT, ACTION OR PROCEEDING MAY BE HEARD AND
DETERMINED IN ANY SUCH COURT.  THE COMPANY IRREVOCABLY WAIVES, TO THE FULLEST
EXTENT IT 

                                      37

MAY EFFECTIVELY DO SO UNDER APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW OR
HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING
BROUGHT IN ANY SUCH COURT AND ANY CLAIM THAT ANY SUCH SUIT, ACTION OR PROCEEDING

          This Agreement may be signed in various counterparts which together
shall constitute one and the same instrument.

          SECTION 2.1.  Form and Dating.
                        --------------- 

          The Securities and the Trustee's certificate of authentication, in
respect thereof, shall be substantially in the form of Exhibit A hereto, which
Exhibit is part of this Indenture.  The Securities may have notations, legends
or endorsements required by law, stock exchange rule or usage.  The Company
shall approve the form of the Securities and any notation, legend or endorsement

                                      12
<PAGE>
 
of Security attached as Exhibit A hereto shall be delivered in writing to the
Trustee.  Each Security shall be dated the date of its authentication.

          The terms and provisions contained in the forms of Securities shall
constitute, and are hereby expressly made, a part of this Indenture and, to the
extent applicable, the Company and the Trustee, by their execution and delivery
of this Indenture, expressly agree to such terms and provisions and to be bound
thereby.

          SECTION 2.    Execution and Authentication.
                        ---------------------------- 

          Two Officers shall sign, or one Officer shall sign and one Officer
shall attest to, the Security for the Company by manual or facsimile signature.
The Company's seal shall be impressed, affixed, imprinted or reproduced on the
Securities and may be in facsimile form.

          If an Officer whose signature is on a Security was an Officer at the
time of such execution but no longer holds that office at the time the Trustee
authenticates the Security, the Security shall be valid nevertheless and the
Company shall nevertheless be bound by the terms of the Securities and this
Indenture.

          A Security shall not be valid until an authorized signatory of the
Trustee manually signs the certificate of authentication on the Security but
such signature shall be conclusive evidence that the Security has been
authenticated pursuant to the terms of this Indenture.

          The Trustee shall authenticate the Securities for original issue in
the aggregate principal amount of up to $200,000,000 upon a written order of the
Company in the form of an Officers' Certificate.  The Officers' Certificate
shall specify the amount of Securities to be authenticated and the date on which
the Securities are to be authenticated.  The aggregate principal amount of
Securities outstanding at any time may not exceed $230,000,000, except as
provided in Section 2.7; provided, that Securities in excess of $200,000,000
                         --------                                           
shall not be issued other than pursuant to the over-allotment option granted by
the Company to the Underwriters as provided in the Underwriting Agreement.  Upon
the written order of the Company in the form of an Officers' Certificate, the
Trustee shall authenticate Securities in

                                      13
<PAGE>
 
substitution of Securities originally issued to reflect any name change of the
Company.

          The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Securities.  Unless otherwise provided in the
appointment, an authenticating agent may authenticate Securities whenever the
Trustee may do so.  Each reference in this Indenture to authentication by the
Trustee includes authentication by such agent.  An authenticating agent has the
same rights as an Agent to deal with the Company, any Affiliate of the Company,
or any of their respective Subsidiaries.

          Securities shall be issuable only in registered form without coupons
in denominations of $1,000 and any integral multiple thereof.

          SECTION 3.    Registrar and Paying Agent.
                        -------------------------- 

          The Company shall maintain an office or agency in the Borough of
Manhattan, The City of New York, where Securities may be presented for
registration of transfer or for exchange ("Registrar") and an office or agency
where Securities may be presented for payment ("Paying Agent") and where notices
and demands to or upon the Company in respect of the Securities may be served.
The Company may act as Registrar or Paying Agent, except that, for the purposes
of Articles III, VIII and X and as otherwise specified in the Indenture, neither
the Company nor any Affiliate of the Company shall act as Paying Agent.  The
Registrar shall keep a register of the Securities and of their transfer and
exchange.  The Company may have one or more co-Registrars and one or more
additional Paying Agents.  The term "Paying Agent" includes any additional
Paying Agent.  The Company hereby initially appoints the Trustee as Registrar
and Paying Agent, and the Trustee hereby initially agrees so to act.

          The Company shall enter into an appropriate written agency agreement
with any Agent not a party to this Indenture, which agreement shall implement
the provisions of this Indenture that relate to such Agent.  The Company shall
promptly notify the Trustee in writing of the name and address of any such
Agent.  If the Company fails to maintain a Registrar or Paying Agent, the
Trustee shall act as such.

                                      14

          The Company initially appoints The Depository Trust Company ("DTC") to
act as Depositary with respect to the Global Securities.

          The Company initially appoints the Trustee to act as Securities
Custodian with respect to the Global Securities.

          SECTION 4.  Paying Agent to Hold Assets in Trust.
                      ------------------------------------ 

          The Company shall require each Paying Agent other than the Trustee to
agree in writing that each Paying Agent shall hold in trust for the benefit of
Holders or the Trustee all assets held by the Paying Agent for the payment of
principal of, premium, if any, or interest on, the Securities (whether such
assets have been distributed to it by the Company or any other obligor on the
Securities), and shall notify the Trustee in writing of any Default in making
any such payment.  If either of the Company or a Subsidiary of the Company acts
as Paying Agent, it shall segregate such assets and hold them as a separate
trust fund for the benefit of the Holders or the Trustee.  The Company at any
time may require a Paying Agent to distribute all assets held by it to the
Trustee and account for any assets disbursed and the Trustee may at any time
during the continuance of any payment Default, upon written request to a Paying
Agent, require such Paying Agent to distribute all assets held by it to the
Trustee and to account for any assets distributed.  Upon distribution to the
Trustee of all assets that shall have been delivered by the Company to the
Paying Agent, the Paying Agent (if other than the Company or an Affiliate of the
Company) shall have no further liability for such assets.

          SECTION 5.  Securityholder Lists.
                      -------------------- 

          The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Holders.  If the Trustee is not the Registrar, the Company shall furnish to the
Trustee on or before the third Business Day preceding each Interest Payment Date
and at such other times as the Trustee may request in writing a list in such
form and as of such date as the Trustee reasonably may require of the names and
addresses of Holders.

               SECTION 6.  Transfer and Exchange.
                           --------------------- 

(a) Transfer and Exchange of Definitive Securities. When Definitive Securities
are presented to the Registrar or a co-Registrar with a request:

                              (x) to register the transfer of such Definitive
Securities; or

                              (y) to exchange such Definitive Securities for an
equal principal amount of Definitive Securities of other authorized
denominations;

the Registrar or co-Registrar shall register the transfer or make the exchange
as requested if its reasonable requirements for such transaction are met;
provided, however, that the Definitive Securities surrendered for transfer or
- --------  -------                                                            
exchange shall be duly endorsed or accompanied by a written instrument of
transfer in form reasonably satisfactory to the Company and the Registrar or co-
Registrar, duly executed by the Holder thereof or his attorney duly authorized
in writing.

          (b)  Restrictions on Transfer of a Definitive Security for a
               -------------------------------------------------------
Beneficial Interest in a Global Security.  A Definitive Security may not be
- ----------------------------------------                                   
exchanged for a beneficial interest in a Global Security except upon
satisfaction of the requirements set forth below.  Upon receipt by the Trustee
of a Definitive Security, duly endorsed or accompanied by appropriate
instruments of transfer, in form satisfactory to the Trustee, together with
written instructions directing the Trustee to make, or to direct the Securities
Custodian to make, an endorsement on the Global Security to reflect an increase
in the aggregate principal amount of the Securities represented by the Global
Security, then the Trustee shall cancel such Definitive Security and cause, or
direct the Securities Custodian to cause, in accordance with the standing
instructions and procedures existing between the Depositary and the Securities
Custodian, the aggregate principal amount of Securities represented by the
Global Security to be increased accordingly.  If no Global Securities are then
outstanding, the Company shall issue and the Trustee shall authenticate a new
Global Security in the appropriate principal amount.

          (c)  Transfer and Exchange of Global Securities.  The transfer and
               ------------------------------------------                   
exchange of Global Securities or

                                      16
<PAGE>
 
beneficial interests therein shall be effected through the Depositary, in
accordance with this Indenture (including the restrictions on transfer set forth
herein) and the procedures of the Depositary therefor.

          (d) Transfer of a Beneficial Interest in a Global Security for a
              ------------------------------------------------------------
Definitive Security.
- -------------------

               (i)  Upon receipt by the Trustee of written instructions or such
     other form of instructions as is customary for the Depositary from the
     Depositary or its nominee on behalf of any Person having a beneficial
     interest in a Global Security and upon receipt by the Trustee of a written
     order or such other form of instructions as is customary for the Depositary
     or the Person designated by the Depositary as having such a beneficial
     interest in a Global Security only, and if such beneficial interest is
     being transferred to the Person designated by the Depositary as being the
     beneficial owner, a certification (which may be submitted by facsimile)
     from such person to that effect (in substantially the form set forth on the
     reverse of the Security), then the Trustee or the Securities Custodian, at
     the direction of the Trustee, will cause, in accordance with the standing
     instructions and procedures existing between the Depositary and the
     Securities Custodian, the aggregate principal amount of the Global Security
     to be reduced and, following such reduction, the Company will execute and,
     upon receipt of an authentication order in the form of an Officers'
     Certificate, the Trustee will authenticate and deliver to the transferee a
     Definitive Security.

               (ii)  Definitive Securities issued in exchange for a beneficial
     interest in a Global Security pursuant to this Section 2.6(d) shall be
     registered in such names and in such authorized denominations as the
     Depositary, pursuant to instructions from its direct or indirect
     participants or otherwise, shall instruct the Trustee.  The Trustee shall
     deliver such Definitive Securities to the persons in whose names such
     Securities are so registered.

          (e)  Restrictions on Transfer and Exchange of Global Securities.
               ----------------------------------------------------------  
Notwithstanding any other provisions of this Indenture (other than the
provisions set forth in subsection (f) of this Section 2.6), a Global Security
may

                                      17
<PAGE>
 
not be transferred as a whole except by the Depositary to a nominee of the
Depositary or by a nominee of the Depositary to the Depositary or another
nominee of the Depositary or by the Depositary or any such nominee to a
successor Depositary or a nominee of such successor Depositary.

          (f) Authentication of Definitive Securities in Absence of Depositary.
              ----------------------------------------------------------------
If at any time:

               (i)  the Depositary for the Securities notifies the Company and
     the Company notifies the Trustee in writing that the Depositary is no
     longer willing or able to continue as Depositary for the Global Securities
     and a successor Depositary for the Global Securities is not appointed by
     the Company within 90 days after delivery of such notice; or

               (ii)  the Company, in its sole discretion, notifies the Trustee
     in writing that it elects to cause the issuance of Definitive Securities
     under this Indenture;

then the Company will execute, and the Trustee, upon receipt of an Officers'
Certificate requesting the authentication and delivery of Definitive Securities,
will authenticate and deliver Definitive Securities, in an aggregate principal
amount equal to the principal amount of the Global Securities, in exchange for
such Global Securities.

          (g)  Cancellation and/or Adjustment of Global Security.  At such time
               -------------------------------------------------               
as all beneficial interests in a Global Security have either been exchanged for
Definitive Securities, redeemed, repurchased or cancelled, such Global Security
shall be returned to or retained and cancelled by the Trustee.  At any time
prior to such cancellation, if any beneficial interest in a Global Security is
exchanged for Definitive Securities, redeemed, repurchased or cancelled, the
principal amount of Securities represented by such Global Security shall be
reduced and an endorsement shall be made on such Global Security, by the Trustee
or the Securities Custodian, at the direction of the Trustee, to reflect such
reduction.

          (h) Obligations with respect to Transfers and Exchanges of Definitive
              -----------------------------------------------------------------
Securities.
- ----------

                                      18
<PAGE>
 
               (i)  To permit registrations of transfers and exchanges, the
     Company shall execute and the Trustee shall authenticate Definitive
     Securities and Global Securities at the Registrar's or co-Registrar's
     request.

               (ii)  No service charge shall be made for any registration of
     transfer or exchange, but the Company may require payment of a sum
     sufficient to cover any transfer tax, assessments, or similar governmental
     charge payable in connection therewith (other than any such transfer taxes,
     assessments, or similar governmental charge payable upon exchanges or
     transfers pursuant to Section 2.2 (fourth paragraph), 2.10, 3.7, 9.5, or
     10.1 (final paragraph)).

               (iii)  The Registrar or co-Registrar shall not be required to
     register the transfer of or exchange of (a) any Definitive Security
     selected for redemption in whole or in part pursuant to Article III, except
     the unredeemed portion of any Definitive Security being redeemed in part,
     or (b) any Security for a period beginning 15 days before the mailing of a
     notice of an offer to repurchase pursuant to Article XI hereof or the
     mailing of a notice of redemption of Securities pursuant to Article III
     hereof and ending at the close of business on the day of such mailing.

          SECTION 7.  Replacement Securities.
                      ---------------------- 

          If a mutilated Security is surrendered to the Trustee or if the Holder
of a Security claims and submits an affidavit or other evidence, satisfactory to
the Trustee, to the Trustee to the effect that the Security has been lost,
destroyed or wrongfully taken, the Company shall issue and the Trustee shall
authenticate a replacement Security if the Trustee's requirements are met. If
required by the Trustee or the Company, such Holder must provide an indemnity
bond or other indemnity, sufficient in the judgment of both the Company and the
Trustee, to protect the Company, the Trustee or any Agent from any loss which
any of them may suffer if a Security is replaced. The Company may charge such
Holder for its reasonable, out-of-pocket expenses in replacing a Security.

          Every replacement Security is an additional obligation of the Company.

                                      19
<PAGE>
 
          SECTION 8. Outstanding Securities.
                     ---------------------- 

          Securities outstanding at any time are all the Securities that have
been authenticated by the Trustee (including any Security represented by a
Global Security) except those cancelled by it, those delivered to it for
cancellation, those reductions in the interest in a Global Security effected by
the Trustee hereunder and those described in this Section 2.8 as not
outstanding. A Security does not cease to be outstanding because the Company or
an Affiliate of the Company holds the Security, except as provided in Section
2.9.

          If a Security is replaced pursuant to Section 2.7 (other than a
mutilated Security surrendered for replacement), it ceases to be outstanding
unless the Trustee receives proof satisfactory to it that the replaced Security
is held by a bona fide purchaser. A mutilated Security ceases to be outstanding
             ---- ----
upon surrender of such Security and replacement thereof pursuant to Section 2.7.

          If on a Redemption Date the Paying Agent (other than the Company or an
Affiliate of the Company) holds Cash or U.S. Government Obligations sufficient
to pay all of the principal and interest due on the Securities payable on that
date in accordance with Section 3.6 hereof and payment of the Securities called
for redemption is not otherwise prohibited pursuant to Article XI hereof or
otherwise, then on and after that date such Securities cease to be outstanding
and interest on them ceases to accrue.

          SECTION 9. Treasury Securities.
                     ------------------- 

          In determining whether the Holders of the required principal amount of
Securities have concurred in any direction, amendment, supplement, waiver or
consent, Securities owned by the Company or an Affiliate of the Company shall be
disregarded, except that, for the purposes of determining whether the Trustee
shall be protected in relying on any such direction, amendment, supplement,
waiver or consent, only Securities that the Trustee knows are so owned shall be
disregarded.

          SECTION 10.  Temporary Securities.
                       -------------------- 

          Until Definitive Securities are ready for delivery, the Company may
prepare and the Trustee shall authen-

                                      20
<PAGE>
 
ticate temporary Securities. Temporary Securities shall be substantially in the
form of Definitive Securities but may have variations that the Company
reasonably and in good faith considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and the Trustee shall
authenticate Definitive Securities in exchange for temporary Securities. Until
so exchanged, the temporary Securities shall in all respects be entitled to the
same benefits under this Indenture as permanent Securities authenticated and
delivered hereunder.

          SECTION 11.  Cancellation.
                       ------------ 

          The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar and the Paying Agent shall forward to the Trustee
any Securities surrendered to them for transfer, exchange or payment. The
Trustee, or at the direction of the Trustee, the Registrar or the Paying Agent
(other than the Company or an Affiliate of the Company), and no one else, shall
cancel and, at the written direction of the Company, shall dispose of all
Securities surrendered for transfer, exchange, payment or cancellation. Subject
to Section 2.7, the Company may not issue new Securities to replace Securities
that have been paid or delivered to the Trustee for cancellation. No Securities
shall be authenticated in lieu of or in exchange for any Securities cancelled as
provided in this Section 2.11, except as expressly permitted in the form of
Securities and as permitted by this Indenture.

          SECTION 12.  Defaulted Interest.
                       ------------------ 

          Interest on any Security which is payable, and is punctually paid or
duly provided for, on any Interest Payment Date shall be paid to the person in
whose name that Security (or one or more predecessor Securities) is registered
at the close of business on the Record Date for such interest.

          Any interest on any Security which is payable, but is not punctually
paid or duly provided for, on any Interest Payment Date plus, to the extent
lawful, any interest payable on the defaulted interest (herein called "Defaulted
Interest") shall forthwith cease to be payable to the registered holder on the
relevant Record Date, and such Defaulted Interest may be paid by the Company, at
its election in each case, as provided in clause (1) or (2) below:

                                      21
<PAGE>
 
               (1)  The Company may elect to make payment of any Defaulted
     Interest to the persons in whose names the Securities (or their respective
     predecessor Securities) are registered at the close of business on a
     Special Record Date for the payment of such Defaulted Interest, which shall
     be fixed in the following manner.  The Company shall notify the Trustee in
     writing of the amount of Defaulted Interest proposed to be paid on each
     Security and the date of the proposed payment, and at the same time the
     Company shall deposit with the Trustee an amount of Cash equal to the
     aggregate amount proposed to be paid in respect of such Defaulted Interest
     or shall make arrangements satisfactory to the Trustee for such deposit
     prior to the date of the proposed payment, such Cash when deposited to be
     held in trust for the benefit of the persons entitled to such Defaulted
     Interest as provided in this clause (1).  Thereupon the Trustee shall fix a
     Special Record Date for the payment of such Defaulted Interest which shall
     be not more than 15 days and not less than 10 days prior to the date of the
     proposed payment and not less than 10 days after the receipt by the Trustee
     of the notice of the proposed payment.  The Trustee shall promptly notify
     the Company of such Special Record Date and, in the name and at the expense
     of the Company, shall cause notice of the proposed payment of such
     Defaulted Interest and the Special Record Date therefor to be mailed,
     first-class postage prepaid, to each Holder at his address as it appears in
     the Security register not less than 10 days prior to such Special Record
     Date.  Notice of the proposed payment of such Defaulted Interest and the
     Special Record Date therefor having been mailed as aforesaid, such
     Defaulted Interest shall be paid to the persons in whose names the
     Securities (or their respective predecessor Securities) are registered on
     such Special Record Date and shall no longer be payable pursuant to the
     following clause (2).

               (2)  The Company may make payment of any Defaulted Interest in
     any other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Securities may be listed, and upon such
     notice as may be required by such exchange, if, after notice given by the
     Company to the Trustee of the proposed payment pursuant to this clause,
     such manner shall be deemed practicable by the Trustee.

                                      22
<PAGE>
 
          Subject to the foregoing provisions of this Section 2.12, each
Security delivered under this Indenture upon transfer of or in exchange for or
in lieu of any other Security shall carry the rights to interest accrued and
unpaid, and to accrue, which were carried by such other Security.

                                   REDEMPTION

          SECTION 1.  Right of Redemption.
                      ------------------- 

          Redemption of Securities, as permitted by any provision of this
Indenture, shall be made in accordance with Paragraph 5 of the Securities and
this Article III.  The Company will not have the right to redeem any Securities
prior to December __, 1999.  At any time on or after December __, 1999, upon no
less than 30 nor more than 60 days notice to each Holder of Notes, the Company
will have the right to redeem all or any part of the Securities at the
Redemption Prices specified in Paragraph 5 therein under the caption
"Redemption," in each case including accrued and unpaid interest, if any, to the
Redemption Date.

          SECTION 2.  Notices to Trustee.
                      ------------------ 

          If the Company elects to redeem Securities pursuant to Paragraph 5 of
the Securities, it shall notify the Trustee in writing of the Redemption Date
and the principal amount of Securities to be redeemed and whether it wants the
Trustee to give notice of redemption to the Holders.

          If the Company elects to reduce the principal amount of Securities to
be redeemed pursuant to Paragraph 5 of the Securities by crediting against any
such redemption Securities it has not previously delivered to the Trustee for
cancellation, it shall so notify the Trustee of the amount of the reduction and
deliver such Securities with such notice.

          The Company shall give each notice to the Trustee provided for in this
Section 3.2 at least 45 days before the Redemption Date (unless a shorter notice
shall be satisfactory to the Trustee).  Any such notice may be cancelled at any
time prior to notice of such redemption being mailed to any Holder and shall
thereby be void and of no effect.

                                      23

          SECTION 3.  Selection of Securities to Be Redeemed.
                      -------------------------------------- 

          If less than all of the Securities are to be redeemed pursuant to
Paragraph 5 thereof, the Trustee shall select the Securities to be redeemed on a
pro rata basis, by lot or by such other method as the Trustee shall determine to
be fair and appropriate and in such manner as complies with any applicable
depositary, legal and stock exchange requirements.

          The Trustee shall make the selection from the Securities outstanding
and not previously called for redemption and shall promptly notify the Company
in writing of the Securities selected for redemption and, in the case of any
Security selected for partial redemption, the principal amount thereof to be
redeemed.  Securities in denominations of $1,000 may be redeemed only in whole.
The Trustee may select for redemption portions (equal to $1,000 or any integral
multiple thereof) of the principal of Securities that have denominations larger
than $1,000.  Provisions of this Indenture that apply to Securities called for
redemption also apply to portions of Securities called for redemption.

          SECTION 4.  Notice of Redemption.
                      -------------------- 

          At least 30 days but not more than 60 days before a Redemption Date,
the Company shall mail a notice of redemption by first-class mail, postage
prepaid, to the Trustee and each Holder whose Securities are to be redeemed.  At
the Company's written request to the Trustee not less than 75 days prior to the
Redemption Date, in the case of a partial redemption, and not less than 45 days
prior to the Redemption Date in the case of a total redemption (unless a shorter
notice shall be satisfactory to the Trustee), the Trustee shall give the notice
of redemption in the Company's name and at the Company's expense.  Each notice
for redemption shall identify the Securities to be redeemed and shall state:

               (1)  the Redemption Date, and that the Securities called for
     redemption may not be converted after the Business Day prior to the
     Redemption Date;

                                      24
<PAGE>
 
               (2)  the Redemption Price, including the amount of accrued and
     unpaid interest, if any, to be paid upon such redemption;

               (3) the name and address of the Paying Agent;

               (4)  that Securities called for redemption must be surrendered to
     the Paying Agent at the address specified in such notice to collect the
     Redemption Price;

               (5)  that, unless (a) the Company defaults in its obligation to
     deposit Cash with the Paying Agent in accordance with Section 3.6 hereof or
     (b) such redemption payment is prohibited pursuant to Article XII hereof or
     otherwise, interest on Securities called for redemption ceases to accrue on
     and after the Redemption Date and the only remaining right of the Holders
     of such Securities is to receive payment of the Redemption Price, including
     accrued and unpaid interest, if any, to the Redemption Date, upon surrender
     to the Paying Agent of the Securities called for redemption and to be
     redeemed;

               (6)  if any Security is being redeemed in part, the portion of
     the principal amount, equal to $1,000 or any integral multiple thereof, of
     such Security to be redeemed and that, after the Redemption Date, and upon
     surrender of such Security, a new Security or Securities in aggregate
     principal amount equal to the unredeemed portion thereof will be issued;

               (7)  if less than all the Securities are to be redeemed, the
     identification of the particular Securities (or portion thereof) to be
     redeemed, as well as the aggregate principal amount of such Securities to
     be redeemed and the aggregate principal amount of Securities to be
     outstanding after such partial redemption;

               (8) the CUSIP number of the Securities to be redeemed; and

               (9)  that the notice is being sent pursuant to this Section 3.4
     and pursuant to the redemption provisions of Paragraph 5 of the Securities.

          SECTION 5.  Effect of Notice of Redemption.
                      ------------------------------ 

          Once notice of redemption is mailed in accordance with Section 3.4,
Securities called for redemption become due and payable on the Redemption Date
and at the Redemption Price, including accrued and unpaid interest, if any, to
the Redemption Date.  Upon surrender to the Trustee or Paying Agent, such
Securities called for redemption shall be paid at the Redemption Price,
including accrued and unpaid interest, if any, to the Redemption Date; provided
                                                                       --------
that if the Redemption Date is after a regular Record Date and on or prior to
the corresponding Interest Payment Date, the accrued interest to the Redemption
Date, if any, shall be payable to the Holder of the redeemed Securities
registered on the relevant Record Date; and provided, further, that if a
                                            --------  -------           
Redemption Date is a Legal Holiday, payment shall be made on the next succeeding
Business Day and no interest shall accrue for the period from such Redemption
Date to such succeeding Business Day.

          SECTION 6.  Deposit of Redemption Price.
                      --------------------------- 

          On or prior to the Redemption Date, the Company shall deposit with the
Paying Agent (other than the Company or an Affiliate of the Company) Cash
sufficient to pay the Redemption Price of, including accrued and unpaid interest
on, all Securities to be redeemed on such Redemption Date (other than Securities
or portions thereof called for redemption on that date that have been delivered
by the Company to the Trustee for cancellation).  The Paying Agent shall
promptly return to the Company any Cash so deposited which is not required for
that purpose upon the written request of the Company.

          If the Company complies with the preceding paragraph and the other
provisions of this Article III and payment of the Securities called for
redemption is not prohibited under Article XII or otherwise, interest on the
Securities to be redeemed will cease to accrue on the applicable Redemption
Date, whether or not such Securities are presented for payment.  Notwithstanding
anything herein to the contrary, if any Security surrendered for redemption in
the manner provided in the Securities shall not be so paid upon surrender for
redemption because of the failure of the Company to comply with the preceding
paragraph, interest shall continue to accrue and be paid from the Redemption
Date until such payment is made on the unpaid principal,

                                      26
<PAGE>
 
and, to the extent lawful, on any interest not paid on such unpaid principal, in
each case at the rate and in the manner provided in Section 4.1 hereof and in
the Security.

          SECTION 7.  Securities Redeemed in Part.
                      --------------------------- 

          Upon surrender of a Security that is to be redeemed in part, the
Company shall execute and the Trustee shall authenticate and deliver to the
Holder, without service charge to the Holder, a new Security or Securities equal
in principal amount to the unredeemed portion of the Security surrendered.

                                   ARTICLE IV

                                   COVENANTS

          SECTION 1.  Payment of Principal and Interest on Securities.
                      ----------------------------------------------- 

          The Company shall pay the principal of and interest on the Securities
on the dates and in the manner provided in the Securities.  An installment of

of the Company) holds for the benefit of the Holders, on or before 10:00 a.m.

New York, an office or agency where Securities may be presented or surrendered

exchange and for conversion and where notices and demands to or upon the Company
in respect of the Securities and this Indenture may be served.  The Company
shall give prompt written notice to the Trustee of the location, and any change
in the location, of such office or agency.  If at any time the Company shall
fail to maintain any such

                                      27
<PAGE>
 
required office or agency or shall fail to furnish the Trustee with the address
thereof, such presentations, surrenders, notices and demands may be made or
served at the address of the Trustee set forth in Section 13.2.

          The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations;
                                                                         
provided, however, that no such designation or rescission shall in any manner
- --------  -------

existence and the corporate or other existence of each of its Significant
Subsidiaries in accordance with the respective organizational documents of each
of them and the rights (charter and statutory) and corporate franchises of the
Company and each of its Significant Subsidiaries; provided, however, that the
                                                  --------  -------          
Company shall not be required to preserve, with respect to itself, any right or
franchise, and with respect to any of its Significant Subsidiaries, any such
existence, right or franchise, if (a) the Company shall determine that the
preservation thereof is no longer desirable in the conduct of the business of
such entity and (b) the loss thereof is not disadvantageous in any material
respect to the Holders.

          SECTION 4.  Payment of Taxes and Other Claims.
                      --------------------------------- 

          Except with respect to immaterial items, the Company shall, and shall

penalties, interest and additions to taxes) levied or imposed upon the Company
or any of its Significant Subsidiaries or any of their respective prop-

                                      28

nor any Significant Subsidiary shall be required to pay or discharge or cause to
be paid or discharged any such tax, assessment, charge or claim whose amount,
applicability or validity is being contested in good faith by appropriate
proceedings and for which such disputed amounts the need for adequate reserves
has been reviewed in accordance with GAAP.

          SECTION 5.  Maintenance of Properties and Insurance.
                      --------------------------------------- 

          The Company shall cause all material properties used or useful to the
conduct of its business and the business of each of its Significant Subsidiaries
to be maintained and kept in good condition, repair and working order
(reasonable wear and tear excepted) and supplied with all necessary equipment
and shall cause to be made all necessary repairs, renewals, replacements,
betterments and improvements thereof, all as in their reasonable judgment may be
necessary, so that the business carried on in connection therewith may be

4.5 shall prevent the Company or any Significant Subsidiary from discontinuing
any operation or maintenance of any of such properties, or disposing of any of
them, if such discontinuance or disposal is (a), in the judgment of the Company,
desirable in the conduct of the business of such entity and (b) not
disadvantageous in any material respect to the Holders.

          The Company shall provide, or cause to be provided, for itself and
each of its Significant Subsidiaries, insurance (including appropriate self-
insurance) against loss or damage of the kinds that, in the reasonable, good
faith opinion of the Company is adequate and appropriate for the conduct of the
business of the Company and such Significant Subsidiaries in a prudent manner,
with (except for self-insurance) reputable insurers or with the government of
the United States of America or an agency or instrumentality thereof, in such
amounts, with such deductibles, and by such methods as shall be customary, in
the reasonable, good faith opinion of the Company and adequate and appropriate
for the conduct of the business of the Company and such Significant

failures) would not have a material adverse effect on the financial condition or
results of operations of the Company or such Significant Subsidiary.

activities of its Significant Subsidiaries during the preceding fiscal year has
been made under the supervision of the signing Officers with a view to
determining whether the Company has kept, observed, performed and fulfilled its
obligations under this Indenture and further stating, as to each such Officer
signing such certificate, whether or not the signer knows of any failure by the
Company or any Subsidiary of the Company to comply with any conditions or
covenants in this Indenture and, if such signer does know of such a failure to
comply, the certificate shall describe such failure with particularity. The
Officers' Certificate shall also notify the Trustee should the relevant fiscal
year end on any date other than the current fiscal year end date.

               (b) The Company shall, so long as any of the Securities are
outstanding, deliver to the Trustee, promptly upon becoming aware of any
Default, Event of Default or fact which would prohibit the making of any payment
to or by the Trustee in respect of the Securities, an Officers' Certificate

Holders.

included in reports filed with the SEC if the Company was subject to the

to annual information only, a report thereon by the Company's certified
independent public accountants as such would be required in such reports to the
SEC and, in each case, together with a management's discussion and analysis of
financial condition and results of operations which would be so required.

          The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension law or any usury law or
other law which would prohibit or forgive the Company  from paying all or any
portion of the principal of, premium of, interest on, the Securities as
contemplated herein, wherever enacted, now or at any time hereafter in force, or
which may affect the covenants or the performance of this Indenture; and (to the
extent that it may lawfully do so)  the Company hereby expressly waives all
benefit or advantage of any such law, and covenants that it will not hinder,
delay or impede the execution of any power herein granted to the Trustee, but
will suffer and permit the execution of every such power as though no such law
had been enacted.

               (6)  the Company or any of its Significant Subsidiaries shall
     institute proceedings to be adjudicated a voluntary bankrupt, or shall
     consent to the filing of a bankruptcy proceeding against it, or shall file
     a petition or answer or consent seeking reorganization under any bankruptcy
     or similar law or similar statute, or shall consent to the filing of any
     such petition, or shall consent to the appointment of a Custodian,
     receiver, liquidator, trustee, or assignee in bankruptcy or insolvency of
     it or any of its assets

     or property, or shall make a general assignment for the benefit of
     creditors, or shall admit in writing its inability to pay its debts
     generally as they become due, or shall, within the meaning of any
     Bankruptcy Law, become insolvent, fail generally to pay its debts as they
     become due, or take any corporate action in furtherance of or to
     facilitate, conditionally or otherwise, any of the foregoing; or

               (7)  final unsatisfied judgments not covered by insurance
     (including self-insurance), or the issuance of any warrant of attachment
     against any portion of the property or assets of the Company or any of its
     Subsidiaries, aggregating in excess of $25,000,000 at any one time shall
     have been rendered against the Company or any of its Subsidiaries and not
     have been stayed, bonded or discharged for a period (during which execution
     shall not be effectively stayed) of 75 days (or, in the case of any such
     final judgment which provides for payment over time, which shall so remain
     unstayed, unbonded or undischarged beyond any applicable payment date
     provided therein).

          Notwithstanding the 60-day period and notice requirement contained in
Section 6.1(3) above, with respect to a default under Article X the 60-day
period referred to in Section 6.1(3) shall be deemed to have begun as of the
date the Change of Control notice is required to be sent in the event that the
Company has not complied with the provisions of Section 11.1 and the Trustee or
Holders of at least 25% in principal amount of the outstanding Securities
thereafter give the Notice of Default referred to in Section 6.1(3) to the
Company and, if applicable, the Trustee; provided, however, that if the breach
                                         --------  -------                    
or default is a result of a default in the payment when due of the Repurchase
Price on the Repurchase Date, such Event of Default shall be deemed, for
purposes of this Section 6.1, to arise no later than on the Final Repurchase
Payment Date.

          If a Default occurs and is continuing, the Trustee shall, within 90
days after the occurrence of such default, give to the Holders notice of such
default.

          SECTION 6.2.  Acceleration of Maturity Date; Rescission and Annulment.
                        ------------------------------------------------------- 

          If an Event of Default (other than an Event of Default specified in
Section 6.1(5) or (6) relating to the Company or any of its Subsidiaries) occurs
and is continuing, then, and in every such case, unless the principal of all of
the Securities shall have already become due and payable, either the Trustee or
the Holders of not less than 25% in aggregate principal amount of then
outstanding Securities, by a notice in writing to the Company (and to the
Trustee if given by Holders) (an "Acceleration Notice"), may declare all of the
principal of the Securities (or the Repurchase Price if the Event of Default
includes failure to pay the Repurchase Price, determined as set forth below),
including in each case accrued interest thereon, to be due and payable
immediately.  If an Event of Default specified in Section 6.1(5) or (6) relating
to the Company or any Significant Subsidiary occurs, all principal, accrued
interest thereon will be immediately due and payable on all outstanding
Securities without any declaration or other act on the part of Trustee or the
Holders.

          At any time after such a declaration of acceleration has been made and
before a judgment or decree for payment of the money due has been obtained by
the Trustee as hereinafter provided in this Article VI, the Holders of no less
than a majority in aggregate principal amount of then outstanding Securities, by
written notice to the Company and the Trustee, may rescind, on behalf of all
Holders, any such declaration of acceleration if:

               (1)  the Company has paid or deposited with the Trustee Cash
     sufficient to pay

                                   (A)
               all overdue interest on all Securities,

                                   (B)  
               the principal of (and premium, if any,
               applicable to) any Securities which
               would then be due otherwise than by such
               declaration of acceleration, and
               interest thereon at the rate borne by
               the Securities,

                                   (C)  
               to the extent that payment of such
               interest is lawful,

                                      36
<PAGE>
 
               interest upon overdue interest at the
               rate borne by the Securities,

                                   (D)  
               all sums paid or advanced by the Trustee
               hereunder and the compensation,
               expenses, disbursements and advances of
               the Trustee, its agents and counsel; and

                    (2) all Events of Default, other than the non-payment of the
principal of, premium, if any, and interest on Securities that have become due
solely by such declaration of acceleration, have been cured or waived as
provided in Section 6.12, including, if applicable, any Event of Default
relating to the covenants contained in Section 10.1.

Notwithstanding the previous sentence of this Section 6.2, no waiver shall be
effective against any Holder for any Event of Default or event which with notice
or lapse of time or both would be an Event of Default with respect to any
covenant or provision which cannot be modified or amended without the consent of
the Holder of each outstanding Security affected thereby, unless all such
affected Holders agree, in writing, to waive such Event of Default or other
event.  No such waiver shall cure or waive any subsequent Default or Event of
Default or impair any right consequent thereon.

          SECTION 3.  Collection of Indebtedness and Suits for Enforcement by
                      -------------------------------------------------------
Trustee.
- ------- 

          The Company covenants that if an Event of Default in payment of
principal, premium or interest specified in clause (1) or (2) of Section 6.1
occurs and is continuing, the Company shall, upon demand of the Trustee, pay to
it, for the benefit of the Holders of such Securities, the whole amount then due
and payable on such Securities for principal, premium (if any), interest and, to
the extent that payment of such interest shall be legally enforceable, interest
on any overdue principal (and premium, if any) and on any overdue interest, at
the rate borne by the Securities, and, in addition thereto, such further amount
as shall be sufficient to cover the reasonable costs and expenses of collection,
including reasonable compensation to, and expenses, disbursements and advances
of the Trustee, its agents and counsel.

                                      37
<PAGE>
 
          If the Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust in favor of the
Holders, may institute a judicial proceeding for the collection of the sums so
due and unpaid, may prosecute such proceeding to judgment or final decree and
may enforce the same against the Company or any other obligor upon the
Securities and collect the moneys adjudged or decreed to be payable in the
manner provided by law out of the property of the Company or any other obligor
upon the Securities, wherever situated.

          If an Event of Default occurs and is continuing, the Trustee may in
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee shall deem most
effective to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or to enforce any other proper remedy.

          SECTION 4.  Trustee May File Proofs of Claim.
                      -------------------------------- 

          In case of the pendency of any receivership, insolvency, liquidation,
bankruptcy, reorganization, arrangement, adjustment, composition or other
judicial proceeding relative to the Company or any other obligor upon the
Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled
and empowered, by intervention in such proceeding or otherwise to take any and
all actions under the TIA, including

          (1)  to file and prove a claim for the whole amount of principal (and
premium, if any) and interest owing and unpaid in respect of the Securities and
to file such other papers or documents as may be necessary or advisable in order
to have the claims of the Trustee (including any claim for the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agent and
counsel) and of the Holders allowed in such judicial proceeding; and

                                      38
<PAGE>
 
          (2)  to collect and receive any moneys or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.7.

          Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement, adjustment, or composition affecting the Securities
or the rights of any Holder thereof or to authorize the Trustee to vote in
respect of the claim of any Holder in any such proceeding.

          SECTION 5.  Trustee May Enforce Claims Without Possession of
                      ------------------------------------------------
Securities.
- ---------- 

          All rights of action and claims under this Indenture or the Securities
may be prosecuted and enforced by the Trustee without the possession of any of
the Securities or the production thereof in any proceeding relating thereto, and
any such proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust in favor of the Holders, and any recovery of
judgment shall, after provision for the payment of compensation to, and
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities in respect of which
such judgment has been recovered.

          SECTION 6.  Priorities.
                      ---------- 

          Any money collected by the Trustee pursuant to this Article VI shall
be applied in the following order, at the date or dates fixed by the Trustee
and, in case of the distribution of such money on account of principal, premium
(if any) or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

                                      39
<PAGE>
 
          FIRST:  To the Trustee in payment of all amounts due pursuant to
Section 7.7;

          SECOND:  To the holders of Senior Indebtedness to the extent provided
in Article XI;

          THIRD:  To the Holders in payment of the amounts then due and unpaid
for principal of, premium (if any) and interest, the Securities in respect or
for the benefit of which such money has been collected, ratably, without
preference or priority of any kind, according to the amounts due and payable on
such Securities for principal, premium (if any) and interest, respectively; and

          FOURTH:  To whomsoever may be lawfully entitled thereto, the
remainder, if any.

          SECTION 7.  Limitation on Suits.
                      ------------------- 

          No Holder of any Security shall have any right to order or direct the
Trustee to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless:

               (A)  such Holder has previously given written notice to the
     Trustee of a continuing Event of Default;

               (B)  the Holders of not less than 25% in principal amount of then
     outstanding Securities shall have made written request to the Trustee to
     institute proceedings in respect of such Event of Default in its own name
     as Trustee hereunder;

               (C)  such Holder or Holders have offered to the Trustee
     reasonable security or indemnity against the costs, expenses and
     liabilities to be incurred or reasonably probable to be incurred in
     compliance with such request;

               (D)  the Trustee for 60 days after its receipt of such notice,
     request and offer of indemnity has failed to institute any such proceeding;
     and

                                      40
<PAGE>
 
               (E)  no direction inconsistent with such written request has been
     given to the Trustee during such 60-day period by the Holders of a majority
     in principal amount of then outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the Holders.

          SECTION 8.  Unconditional Right of Holders to Receive Principal,
                      ----------------------------------------------------
Premium and Interest.
- -------------------- 

          Notwithstanding any other provision of this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of, premium (if any) and interest on such
Security when due (including, in the case of redemption, the Redemption Price on
the applicable Redemption Date, and in the case of the Repurchase Price, on the
applicable Repurchase Date) and to institute suit for the enforcement of any
such payment after such respective dates, and such rights shall not be impaired
without the consent of such Holder.

          SECTION 9.  Rights and Remedies Cumulative.
                      ------------------------------ 

          Except as otherwise provided with respect to the replacement or
payment of mutilated, destroyed, lost or stolen Securities in Section 2.7, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise.  The assertion or employment of any
right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy.

          SECTION 10.  Delay or Omission Not Waiver.
                       ---------------------------- 

          No delay or omission by the Trustee or by any Holder of any Security
to exercise any right or remedy

                                      41
<PAGE>
 
arising upon any Event of Default shall impair the exercise of any such right or
remedy or constitute a waiver of any such Event of Default.  Every right and
remedy given by this Article VI or by law to the Trustee or to the Holders may
be exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by the Holders, as the case may be.

          SECTION 11.  Control by Holders.
                       ------------------ 

          The Holder or Holders of no less than a majority in aggregate
principal amount of then outstanding Securities shall have the right to direct
the time, method and place of conducting any proceeding for any remedy available
to the Trustee or exercising any trust or power conferred upon the Trustee,
                                                                           
provided, that
- --------      

               (1)  such direction shall not be in conflict with any rule of law
     or with this Indenture,

               (2)  the Trustee shall not determine that the action so directed
     would be unjustly prejudicial to the Holders not taking part in such
     direction, and

               (3)  the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such direction.

          SECTION 12.  Waiver of Past Default.
                       ---------------------- 

               Subject to Section 6.8, the Holder or Holders of not less than a
     majority in aggregate principal amount of then outstanding Securities may,
     on behalf of all Holders, prior to the declaration of acceleration of the
     maturity of the Securities, waive any past default hereunder and its
     consequences, except a default

               (A)  in the payment of the principal of, premium (if any) or
     interest on, any Security not yet cured as specified in clauses (1) and (2)
     of Section 6.1, or

               (B)  in respect of a covenant or provision hereof which, under
     Article IX, cannot be modified or amended without the consent of the Holder
     of each outstanding Security affected.

                                      42
<PAGE>
 
          Upon any such waiver, such default shall cease to exist, and any Event
of Default arising therefrom shall be deemed to have been cured, for every
purpose of this Indenture; but no such waiver shall extend to any subsequent or
other default or impair the exercise of any right arising therefrom.

          SECTION 13.  Undertaking for Costs.
                       --------------------- 

          All parties to this Indenture agree, and each Holder of any Security
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted to be taken by it as Trustee, the filing by any party
litigant in such suit of an undertaking to pay the costs of such suit, and that
such court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section 6.13 shall not apply to any suit instituted
by the Company, to any suit instituted by the Trustee, to any suit instituted by
any Holder, or group of Holders, holding in the aggregate more than 10% in
aggregate principal amount of then outstanding Securities, or to any suit
instituted by any Holder for enforcement of the payment of principal of, premium
(if any) or interest on, any Security on or after the respective Stated Maturity
of such Security (including, in the case of redemption, on or after the
Redemption Date).

          SECTION 14.  Restoration of Rights and Remedies.
                       ---------------------------------- 

          If the Trustee or any Holder has instituted any proceeding to enforce
any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

                                  ARTICLE VII

                                    TRUSTEE

          The Trustee hereby accepts the trust imposed upon it by this Indenture
and covenants and agrees to perform the same, as herein expressed.

          SECTION 1.  Duties of Trustee.
                      ----------------- 

               (a) If a Default or an Event of Default has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture and use the same degree of care and skill in their exercise
as a prudent Person would exercise or use under the circumstances in the conduct
of his own affairs.

               (b) Except during the continuance of a Default or an Event of
Default:

               (1)  The Trustee need perform only those duties as are
     specifically set forth in this Indenture and no others, and no covenants or
     obligations shall be implied in or read into this Indenture which are
     adverse to the Trustee.

               (2)  In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture.  However,
     the Trustee shall examine the certificates and opinions to determine
     whether or not they conform to the requirements of this Indenture.

          (c)  The Trustee may not be relieved from liability for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

               (1)  This paragraph does not limit the effect of paragraph (b) of
     this Section 7.1.

               (2)  The Trustee shall not be liable for any error of judgment
     made in good faith by a Trust Officer, unless it is proved that the Trustee
     was negligent in ascertaining the pertinent facts.

<PAGE>
 
               (3) The Trustee shall not be liable with respect to any action it
takes or omits to take in good faith in accordance with a direction received by
it pursuant to Section 6.11.

               (d) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder or to take or omit to take any action
under this Indenture or at the request, order or direction of the Holders or in
the exercise of any of its rights or powers if it shall have reasonable grounds
for believing that repayment of such funds or adequate indemnity against such
risk or liability is not reasonably assured to it.

               (e) Every provision of this Indenture that in any way relates to
the Trustee is subject to paragraphs (a), (b), (c), (d) and (f) of this Section
7.1.

               (f) The Trustee shall not be liable for interest on any assets
received by it except as the Trustee may agree in writing with the Company.
Assets held in trust by the Trustee need not be segregated from other assets
except to the extent required by law.

          SECTION 2.  Rights of Trustee.
                      ----------------- 

          Subject to Section 7.1:

               (a) The Trustee may rely on any document believed by it to be
genuine and to have been signed or presented by the proper Person. The Trustee
need not investigate any fact or matter stated in the document.

               (b) Before the Trustee acts or refrains from acting, it may
consult with counsel and may require an Officers' Certificate or an Opinion of
Counsel, which shall conform to Sections 13.4 and 13.5. The Trustee shall not be
liable for any action it takes or omits to take in good faith in reliance on
such certificate or advice of counsel.

               (c) The Trustee may act through its attorneys and agents and
shall not be responsible for the misconduct or negligence of any agent appointed
with due care.

                                      45
<PAGE>
 
               (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith which it believes to be authorized or within its
rights or powers conferred upon it by this Indenture.

               (e) The Trustee shall not be bound to make any investigation into
the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, notice, request, direction, consent, order, bond,
debenture, or other paper or document, but the Trustee, in its discretion, may
make such further inquiry or investigation into such facts or matters as it may
see fit.

               (f) The Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request, order or
direction of any of the Holders, pursuant to the provisions of this Indenture,
unless such Holders shall have offered to the Trustee reasonable security or
indemnity against the costs, expenses and liabilities which may be incurred
therein or thereby.

               (g) Unless otherwise specifically provided for in this Indenture,
any demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

               (h) The Trustee shall have no duty to inquire as to the
performance of the Company's covenants in Article IV hereof. In addition, the
Trustee shall not be deemed to have knowledge of any Default or Event of Default
except (i) any Event of Default occurring pursuant to Sections 6.1(1) or 6.1(2)
or 5.1, or (ii) any Default or Event of Default of which the Trustee shall have
received written notification or obtained actual knowledge.

          SECTION 3.  Individual Rights of Trustee.
                      ---------------------------- 

          The Trustee in its individual or any other capacity may become the
owner or pledgee of Securities and may otherwise deal with the Company, any of
its Subsidiaries, or their respective Affiliates with the same rights it would
have if it were not Trustee.  Any Agent may do the same with like rights.
However, the Trustee must comply with Sections 7.10 and 7.11.

          SECTION 4.  Trustee's Disclaimer.
                      -------------------- 

          The Trustee makes no representation as to the validity or adequacy of
this Indenture or the Securities and it shall not be accountable for the
Company's use of the proceeds from the Securities, and it shall not be
responsible for any statement in the Securities, other than the Trustee's
certificate of authentication, or the use or application of any funds received
by a Paying Agent other than the Trustee.

          SECTION 5.  Notice of Default.
                      ----------------- 

          If a Default or an Event of Default occurs and is continuing and if it
is known to the Trustee, the Trustee shall mail to each Securityholder notice of
the uncured Default or Event of Default within 90 days after such Default or
Event of Default occurs.  Except in the case of a Default or an Event of Default
in payment of principal of, premium (if any) or interest on, any Security
(including the payment of the Repurchase Price on the Repurchase Date and the
payment of the Redemption Price on the Redemption Date), the Trustee may
withhold the notice if and so long as a Trust Officer in good faith determines
that withholding the notice is in the interest of the Securityholders.

          SECTION 6.  Reports by Trustee to Holders.
                      ----------------------------- 

          Within 60 days after each December __ beginning with December __,
1997, the Trustee shall, if required by law, mail to each Securityholder as
their names and addresses appear on the Company's register of Securities, a
brief report dated as of such December __ that complies with TIA (S) 313(a) with
respect to any of the following events which may have occurred within the
previous twelve months (but if no such event has occurred within such period no

TIA (S) 310;

               (2)  the creation of or any material change to a relationship
specified in paragraphs (1) through (10) of TIA (S) 310(b);

<PAGE>
 
surrounding the making thereof) made by the Trustee (as such) which remain
unpaid on the date of such report, and for the reimbursement of which it claims
or may claim a lien or charge, prior to that of the Securities, on any property
or funds held or collected by it as Trustee, except that the Trustee shall not
be required (but may elect) to report such advances if such advances so
remaining unpaid aggregate not more than 1/2 of 1% of the principal amount of
the security outstanding on the date of such report;

               (4) the amount, interest rate and maturity date of all other
indebtedness owing by the Company (or by any other obligor on the Securities) to
the Trustee in its individual capacity, on the date of such report, with a brief

in paragraphs (2), (3), (4) or (6) of TIA (S) 311(b);

               (5) any change to the property and funds, if any, physically in
the possession of the Trustee (as such) on the date of such report;

               (6) any change to any release, or release and substitution, of
property subject to the lien of the Indenture (and the consideration therefor,
if any) which has not been previously reported;

               (7)  any additional issue of Securities which the Trustee has not
previously reported; and

               (8) any action taken by the Trustee in the performance of its
duties hereunder which it has not previously reported and which in its opinion
materially affects the Securities, except action in respect of a default, notice
of which has been or is to be withheld by the Trustee in accordance with an
Indenture provision authorized by TIA (S) 315(b).

     (b) The Trustee shall transmit by mail to all Securityholders, as their
names and addresses appear on the Company's register of Securities, a brief
report with respect to the character and amount of any advances (and if the
Trustee elects so to state, the circumstances surrounding the making thereof)
made by the Trustee (as such) since the date of the last report transmitted
pursuant to Subsection 7.6(a) hereof (or if no such report has yet been so

                                      48
<PAGE>
 
transmitted, since the date of execution of this instrument) for the
reimbursement of which it claims or may claim a lien or charge, prior to that of
the Securities, on property or funds held or collected by it as Trustee and
which it has not previously reported pursuant to this Subsection, except that
the Trustee shall not be required (but may elect) to report such advances if
such advances remaining unpaid at any time aggregate 10% or less of the
principal amount of the Securities outstanding at such time, such report to be
transmitted within 90 days of such time.

     (c) A copy of each such report shall, at the time of such transmission to
Securityholders, be filed by the Trustee with each stock exchange upon which the
Securities are listed, with the SEC and with the Company.  The Company will
promptly notify the Trustee when the Securities are listed on any stock
exchange.  The Trustee also shall comply with TIA (S)(S) 313(b) and 313(c).

          SECTION 7.  Compensation and Indemnity.
                      -------------------------- 

          The Company agrees to pay to the Trustee from time to time reasonable
compensation for its services.  The Trustee's compensation shall not be limited
by any law on compensation of a trustee of an express trust.  The Company shall
reimburse the Trustee upon request for all reasonable disbursements, expenses
and advances incurred or made by it.  Such expenses shall include the reasonable
compensation, disbursements and expenses of the Trustee's agents, accountants,
experts and counsel.

          The Company agrees to indemnify the Trustee (in its capacity as
Trustee) and each of its officers, directors, attorneys-in-fact and agents for,
and hold it harmless against, any claim, demand, expense (including but not
limited to reasonable compensation, disbursements and expenses of the Trustee's
agents and counsel), loss or liability incurred by it without negligence or bad
faith on its part, arising out of or in connection with the administration of
this trust and its rights or duties hereunder including the reasonable costs and
expenses of defending itself against any claim or liability in connection with
the exercise or performance of any of its powers or duties hereunder.  The
Trustee shall notify the Company promptly of any claim asserted against the
Trustee for which it may seek indemnity.  The Company shall defend the claim and
the Trustee shall provide reasonable cooperation at the

                                      49
<PAGE>
 
Company's expense in the defense.  The Trustee may have separate counsel and the
Company shall pay the reasonable fees and expenses of such counsel; provided,
                                                                    -------- 
that the Company will not be required to pay such fees and expenses if it
assumes the Trustee's defense and there is no conflict of interest between the
Company and the Trustee in connection with such defense.  The Company need not
pay for any settlement made without its written consent.  The Company need not
reimburse any expense or indemnify against any loss or liability to the extent
incurred by the Trustee through its negligence, bad faith or willful misconduct.

          To secure the Company's payment obligations in this Section 7.7, the
Trustee shall have a lien prior to the Securities on all assets held or
collected by the Trustee, in its capacity as Trustee, except assets held in
trust to pay principal and premium, if any, of or interest on particular
Securities.

          When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.1(5) or (6) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

          The Company's obligations under this Section 7.7 and any lien arising
hereunder shall survive the resignation or removal of the Trustee, the discharge
of the Company's obligations pursuant to Article VIII of this Indenture and any
rejection or termination of this Indenture under any Bankruptcy Law.

          SECTION 8.  Replacement of Trustee.
                      ---------------------- 

          The Trustee may resign by so notifying the Company in writing.  The
Holder or Holders of a majority in principal amount of then outstanding
Securities may remove the Trustee by so notifying the Company and the Trustee in
writing and may appoint a successor trustee with the Company's consent.  The
Company may remove the Trustee if:

               (a) the Trustee fails to comply with Section 7.10;

               (b) the Trustee is adjudged bankrupt or insolvent;

                                      50
<PAGE>
 
               (c) a receiver, Custodian, or other public officer takes charge
of the Trustee or its property; or

               (d) the Trustee becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee.  Within one year after the successor Trustee takes office, the Holder
or Holders of a majority in principal amount of then outstanding Securities may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company.  Immediately after that
and provided that all sums owing to the retiring Trustee provided for in Section
7.7 have been paid, the retiring Trustee shall transfer all property held by it
as trustee to the successor Trustee, subject to the lien provided in Section
7.7, the resignation or removal of the retiring Trustee shall become effective,
and the successor Trustee shall have all the rights, powers and duties of the
Trustee under this Indenture.  A successor Trustee shall mail notice of its
succession to each Holder.

          If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holder or Holders of at least 10% in principal amount of then outstanding
Securities may petition any court of competent jurisdiction for the appointment
of a successor Trustee.

          If the Trustee fails to comply with Section 7.10, any Securityholder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

          Notwithstanding replacement of the Trustee pursuant to this Section
7.8, the Company's obligations under Section 7.7 shall continue for the benefit
of the retiring Trustee.

          SECTION 9.  Successor Trustee by Merger, Etc.
                      ---------------------------------

          If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to, another
corporation, the re-

sulting, surviving or transferee corporation without any further act shall, if
such resulting, surviving or transferee corporation is otherwise eligible
hereunder, be the successor Trustee.

          SECTION 10.  Eligibility; Disqualification.
                       ----------------------------- 

          The Trustee shall at all times satisfy the requirements of TIA (S)
310(a)(1), (2) and (5).  The Trustee shall have a combined capital and surplus
of at least (i) $100,000,000 or (ii) at least $2,500,000 and shall be a
subsidiary of a bank holding company that shall have a combined capital and
surplus of at least $100,000,000, in each case as set forth in its most recent
published annual report of condition.  The Trustee shall comply with TIA (S)
310(b).

          SECTION 11.  Preferential Collection of Claims Against Company.
                       ------------------------------------------------- 

          The Trustee shall comply with TIA (S) 311(a), excluding any creditor
relationship listed in TIA (S) 311(b).  A Trustee who has resigned or been
removed shall be subject to TIA (S) 311(a) to the extent indicated.

                      --------------------------------------- 

          The Company may terminate its obligations under this Indenture

following conditions shall be satisfied:

               (1) The Company has paid all sums payable under the Indenture;

by the Company, for the payment of the principal of, premium, if any, or
interest on any Security and remaining unclaimed for two years after such
principal, premium, if any, or interest has become due and payable shall be paid
to the Company on its request; and the Holder of such Security shall thereafter
look only to the Company for payment thereof, and all liability of the Trustee
or such Paying Agent with respect to such trust money shall thereupon cease.


                                  ARTICLE IX

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

          SECTION 1.  Supplemental Indentures Without Consent of Holders.
                      -------------------------------------------------- 

          Without the consent of any Holder, the Company, when authorized by
Board Resolutions, and the Trustee, at any time and from time to time, may enter
into one or more indentures supplemental hereto, in form satisfactory to the
Trustee, for any of the following purposes:

               (1) to cure any ambiguity, defect, or inconsistency, or to make
any other provisions with respect to matters or questions arising under this
Indenture which shall not be inconsistent with the provisions of this Indenture,
provided, the Company has delivered to the Trustee an Opinion of Counsel
- --------
stating that such change does not adversely affect the rights of any Holder that
such action pursuant to this clause (1) does not adversely affect the interests
of any Holder in any respect;

               (2) to create additional covenants of the Company for the benefit
of the Holders, or to surrender any right or power herein conferred upon the
Company or to make any other change that does not adversely affect the rights of
any Holder, provided, that the Company has delivered to the Trustee an Opinion
            --------
of Counsel stating that such change

                                      53
<PAGE>
 
pursuant to this clause (2) does not adversely affect the rights of any Holder;

               (3) to provide for collateral for or guarantors of the
Securities;

               (4) to evidence the succession of another Person to the Company
and the assumption by any such successor of the obligations of the Company
herein and in the Securities in accordance with Article V; or

               (5) to comply with the TIA.

          SECTION 2. Amendments, Supplemental Indentures and Waivers with
                     ----------------------------------------------------
Consent of Holders.
- ------------------

          Subject to Section 6.8 and the last sentence of this paragraph, with
the consent of the Holders of not less than a majority in aggregate principal
amount of then outstanding Securities, by written act of said Holders delivered
to the Company and the Trustee, the Company, when authorized by Board
Resolutions, and the Trustee may amend or supplement this Indenture or the
Securities or enter into an indenture or indentures supplemental hereto for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Indenture or the Securities or of modifying in any
manner the rights of the Holders under this Indenture or the Securities. Subject
to Section 6.8 and the last sentence of this paragraph, the Holder or Holders of
not less than a majority in aggregate principal amount of then outstanding
Securities may, in writing, waive compliance by the Company with any provision
of this Indenture or the Securities. Notwithstanding any of the above, however,
no such amendment, supplemental indenture or waiver shall, without the consent
of the Holder of each outstanding Security affected thereby:

               (1) change the Stated Maturity of any Security or reduce the
principal amount thereof or the rate (or extend the time for payment) of
interest thereon or any premium payable upon the redemption thereof, or change
the place of payment where, or the coin or currency in which, any Security or
any premium or the interest thereon is payable, or impair the right to institute
suit for the enforcement of any such payment or the conversion of any Security
on or after the due date thereof (including, in the case of redemption, on or
after the Redemption Date), or reduce the

                                      54
<PAGE>
 
Repurchase Price, or alter the Repurchase Offer or redemption provisions in a
manner adverse to the Holders;

               (2) reduce the percentage in principal amount of the outstanding
Securities, the consent of whose Holders is required for any such amendment,
supplemental indenture or waiver provided for in the Indenture;

               (3) modify any of the provisions of Article XII hereof in a
manner adverse to such Holder or otherwise adversely affect the right of such
Holder to convert Securities; or

               (4) modify any of the waiver provisions, except to increase any
required percentage or to provide that certain other provisions of the Indenture
cannot be modified or waived without the consent of the Holder of each
outstanding Security affected thereby.

          It shall not be necessary for the consent of the Holders under this
Section 9.2 to approve the particular form of any proposed amendment, supplement
or waiver, but it shall be sufficient if such consent approves the substance
thereof.

          After an amendment, supplement or waiver under this Section 9.2
becomes effective, the Company shall mail to the Holders affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such supplemental indenture or
waiver.

          After an amendment, supplement or waiver under this Section 9.2 or
Section 9.4 becomes effective, it shall bind each Holder.

          In connection with any amendment, supplement or waiver under this
Article IX, the Company may, but shall not be obligated to, offer to any Holder
who consents to such amendment, supplement or waiver, or (at the option of the
Company) to all Holders, consideration for consent to such amendment, supplement
or waiver.

                                      55
<PAGE>
 
          SECTION 3.  Compliance with TIA.
                      ------------------- 

          Every amendment, waiver or supplement of this Indenture or the
Securities shall comply with the TIA as then in effect.

          SECTION 4.  Revocation and Effect of Consents.
                      --------------------------------- 

          Until an amendment, waiver or supplement becomes effective, a consent
to it by a Holder is a continuing consent by the Holder and every subsequent
Holder of a Security or portion of a Security that evidences the same debt as
the consenting Holder's Security, even if notation of the consent is not made on
any Security. However, any such Holder or subsequent Holder may revoke the
consent as to his Security or portion of his Security by written notice to the
Company or the Person designated by the Company as the Person to whom consents
should be sent if such revocation is received by the Company or such Person
before the date on which the Trustee receives an Officers' Certificate
certifying that the Holders of the requisite principal amount of Securities have
consented (and not theretofore revoked such consent) to the amendment,
supplement or waiver.

          The Company may, but shall not be obligated to, fix a record date for
the purpose of determining the Holders entitled to consent to any amendment,
supplement or waiver, which record date shall be the date so fixed by the
Company notwithstanding the provisions of the TIA. If a record date is fixed,
then notwithstanding the last sentence of the immediately preceding paragraph,
those Persons who were Holders at such record date, and only those Persons (or
their duly designated proxies), shall be entitled to revoke any consent
previously given, whether or not such Persons continue to be Holders after such
record date. No such consent shall be valid or effective for more than 90 days
after such record date.

          After an amendment, supplement or waiver becomes effective, it shall
bind every Securityholder, unless it makes a change described in any of clauses
(1) through (4) of Section 9.2, in which case, the amendment, supplement or
waiver shall bind only each Holder of a Security who has consented to it and
every subsequent Holder of a Security or portion of a Security that evidences
the same debt as the consenting Holder's Security; provided, that any such
                                                   --------
waiver                                             

                                      56
<PAGE>
 
shall not impair or affect the right of any Holder to receive payment of
principal and premium of and interest on a Security, on or after the respective
dates set for such amounts to become due and payable expressed in such Security,
or to bring suit for the enforcement of any such payment on or after such
respective dates.

          SECTION 5.  Notation on or Exchange of Securities.
                      ------------------------------------- 

          If an amendment, supplement or waiver changes the terms of a Security,
the Trustee may require the Holder of the Security to deliver it to the Trustee
or require the Holder to put an appropriate notation on the Security. The
Trustee may place an appropriate notation on the Security about the changed
terms and return it to the Holder. Alternatively, if the Company or the Trustee
so determines, the Company in exchange for the Security shall issue and the
Trustee shall authenticate a new Security that reflects the changed terms. Any
failure to make the appropriate notation or to issue a new Security shall not
affect the validity of such amendment, supplement or waiver.

          SECTION 6.  Trustee to Sign Amendments, Etc.
                      --------------------------------

          The Trustee shall execute any amendment, supplement or waiver
authorized pursuant to this Article IX; provided, that the Trustee may, but
                                        --------
shall not be obligated to, execute any such amendment, supplement or
waiver which affects the Trustee's own rights, duties or immunities under this
Indenture. The Trustee shall be entitled to receive, and shall be fully
protected in relying upon, an Opinion of Counsel stating that the execution of
any amendment, supplement or waiver authorized pursuant to this Article IX is
authorized or permitted by this Indenture.

Control, at a cash price (the "Repurchase Price") equal to 100% of the principal
amount thereof, together with accrued and unpaid interest to the Repurchase
Date.

               (b) In the event that, pursuant to this Section 10.1, the Company
shall be required to commence an irrevocable and unconditional offer to purchase
Securities (a "Repurchase Offer"), the Company shall follow the procedures set
forth in this Section 10.1 as follows:

               (1)  the Repurchase Offer shall commence within 15 Business Days
     following a Change of Control;

     following its commencement, except to the extent that a longer period is

                                 SUBORDINATION

          SECTION 1.  Securities Subordinated to Senior Indebtedness.
                      ---------------------------------------------- 

          The Company and each Holder, by its acceptance of Securities, agree
that (a) the payment of the principal of

                                      60
<PAGE>
 
and interest on the Securities and (b) any other payment in respect of the
Securities, including on account of the acquisition or redemption of the
Securities by the Company  (including, without limitation, pursuant to Article
X) is subordinated, to the extent and in the manner provided in this Article XI,
to the prior payment in full of all Senior Indebtedness, whether outstanding at
the date of this Indenture or thereafter created, incurred, assumed or
guaranteed, and that these subordination provisions are for the benefit of the
holders of Senior Indebtedness.

          This Article XI shall constitute a continuing offer to all Persons
who, in reliance upon such provisions, become holders of, or continue to hold,
Senior Indebtedness, and such provisions are made for the benefit of the holders
of Senior Indebtedness, and such holders are made obligees hereunder and any one
or more of them may enforce such provisions.

          SECTION 2.  No Payment on Securities in Certain Circumstances.
                      ------------------------------------------------- 

               (a) No payment may be made by the Company on account of the
principal of, premium, if any, or interest on, the Securities, or to acquire any
of the Securities (including repurchases of Securities at the option of the
Holder) for cash or property (other than Junior Securities), or on account of
the redemption provisions of the Securities, (i) upon the maturity of any Senior
Indebtedness of the Company by lapse of time, acceleration (unless waived) or
otherwise, unless and until all principal of, premium, if any, and interest on
such Senior Indebtedness are first paid in full (or such payment is duly
provided for), or (ii) in the event of default in the payment of any principal
of, premium, if any, or interest on any Senior Indebtedness when it becomes due
and payable, whether at maturity or at a date fixed for prepayment or by
declaration or otherwise (a "Payment Default"), unless and until such Payment
Default has been cured or waived or otherwise has ceased to exist.

               (b) Upon (i) the happening of an event of default (other than a
Payment Default) that permits the holders of Senior Indebtedness or their
representative immediately to accelerate its maturity and (ii) written notice of
such event of default given to the Company and the Trustee by the holders of at
least 25% in aggregate principal amount outstanding of such Senior Indebtedness
or

                                      61
<PAGE>
 
their representative (a "Payment Notice"), then, unless and until such event of
default has been cured or waived or otherwise has ceased to exist, no payment
(by set-off or otherwise) may be made by or on behalf of the Company on account
of the principal of, premium, if any, or interest on, the Securities, or to
acquire or repurchase any of the Securities for cash or property, or on account
of the redemption provisions of the Securities, in any such case other than
payments made with Junior Securities of the Company.  Notwithstanding the
foregoing, unless (i) the Senior Indebtedness in respect of which such event of
default exists has been declared due and payable in its entirety within 179 days
after the Payment Notice is delivered as set forth above (the "Payment Blockage
Period"), and (ii) such declaration has not been rescinded or waived, at the end
of the Payment Blockage Period, the Company shall be required to pay all sums
not paid to the Holders of the Securities during the Payment Blockage Period due
to the foregoing prohibitions and to resume all other payments as and when due
on the Securities.  Any number of Payment Notices may be given; provided,
                                                                -------- 
however, that (i) not more than one Payment Notice shall be given within a
- -------                                                                   
period of any 360 consecutive days, and (ii) no default that existed upon the
date of such Payment Notice or the commencement of such Payment Blockage Period
(whether or not such event of default is on the same issue of Senior
Indebtedness) shall be made the basis for the commencement of any other Payment
Blockage Period.

               (c) In the event that, notwithstanding the foregoing provisions
of this Section 11.2, any payment or distribution of assets of the Company
(other than Junior Securities) shall be received by the Trustee or the Holders
at a time when such payment or distribution is prohibited by the provisions of
this Section 11.2, then such payment or distribution (subject to the provisions
of Section 11.7) shall be received and held in trust by the Trustee or such
Holder or Paying Agent for the benefit of the holders of Senior Indebtedness,
and shall be paid or delivered by the Trustee or such Holders or such Paying
Agent, as the case may be, to the holders of Senior Indebtedness remaining
unpaid or unprovided for or their representative or representatives, or to the
trustee or trustees under any indenture pursuant to which any instruments
evidencing any of such Senior Indebtedness may have been issued, ratably
according to the aggregate amounts remaining unpaid on account of the Senior
Indebtedness held or represented by

                                      62
<PAGE>
 
each, for application to the payment of all Senior Indebtedness remaining unpaid
to the extent necessary to pay or to provide for the payment of all such Senior
Indebtedness in full after giving effect to any concurrent payment and
distribution to the holders of such Senior Indebtedness.

          SECTION 3.  Securities Subordinated to Prior Payment of All Senior
                      ------------------------------------------------------
Indebtedness on Dissolution, Liquidation or Reorganization.
- ---------------------------------------------------------- 

          Upon any distribution of assets of the Company upon any dissolution,
winding up, total or partial liquidation or reorganization of the Company,
whether voluntary or involuntary, in bankruptcy, insolvency, receivership or a
similar proceeding or upon assignment for the benefit of creditors or any
marshalling of assets or liabilities:

               (a) the holders of all Senior Indebtedness shall first be
entitled to receive payments in full (or have such payment duly provided for)
before the Holders are entitled to receive any payment on account of the
principal of, premium, if any, and interest on, with respect to the Securities
(other than Junior Securities);

               (b) any payment or distribution of assets of the Company of any
kind or character, whether in cash, property or securities (other than Junior
Securities) to which the Holders or the Trustee on behalf of the Holders would
be entitled (by setoff or otherwise), except for the provisions of this Article
XI, shall be paid by the liquidating trustee or agent or other Person making
such a payment or distribution directly to the holders of Senior Indebtedness or
their representative to the extent necessary to make payment in full of all such
Senior Indebtedness remaining unpaid, after giving effect to any concurrent
payment or distribution to the holders of such Senior Indebtedness; and

               (c) in the event that, notwithstanding the foregoing, any payment
or distribution of assets of the Company of any kind or character, whether in
cash, property or securities (other than Junior Securities), shall be received
by the Trustee or the Holders or any Paying Agent (or, if the Company or any
Affiliate of the Company is acting as its own Paying Agent, money for any such
payment or distribution shall be segregated or held in trust) on account of the
principal of or interest on the Securities

                                      63
<PAGE>
 
before all Senior Indebtedness is paid in full, such payment or distribution
(subject to the provisions of Section 11.7) shall be received and held in trust
by the Trustee or such Holder or Paying Agent for the benefit of the holders of
such Senior Indebtedness, or their respective representative, ratably according
to the respective amounts of such Senior Indebtedness held or represented by
each, to the extent necessary to make payment as provided herein of all such
Senior Indebtedness remaining unpaid after giving effect to all concurrent
payments and distributions and all provisions therefor to or for the holders of
such Senior Indebtedness, but only to the extent that as to any holder of such
Senior Indebtedness, as promptly as practical following notice from the Trustee
to the holders of such Senior Indebtedness that such prohibited payment has been
received by the Trustee, Holder(s) or Paying Agent (or has been segregated as
provided above), such holder (or a representative therefor) notifies the Trustee
of the amounts then due and owing on such Senior Indebtedness, if any, held by
such holder and only the amounts specified in such notices to the Trustee shall
be paid to the holders of such Senior Indebtedness.

          SECTION 4.  Securityholders to Be Subrogated to Rights of Holders
                      -----------------------------------------------------
of Senior Indebtedness.
- ---------------------- 

          Subject to the payment in full of all Senior Indebtedness as provided
herein, the Holders of Securities shall be subrogated to the rights of the
holders of such Senior Indebtedness to receive payments or distributions of
assets of the Company applicable to the Senior Indebtedness until all amounts
owing on the Securities shall be paid in full, and for the purpose of such
subrogation no such payments or distributions to the holders of such Senior
Indebtedness by the Company, or by or on behalf of the Holders by virtue of this
Article XI, which otherwise would have been made to the Holders shall, as
between the Company and the Holders, be deemed to be payment by the Company or
on account of such Senior Indebtedness, it being understood that the provisions
of this Article XI are and are intended solely for the purpose of defining the
relative rights of the Holders, on the one hand, and the holders of such Senior
Indebtedness, on the other hand.

          If any payment or distribution to which the Holders would otherwise
have been entitled but for the provisions of this Article XI shall have been
applied, pursuant

                                      64
<PAGE>
 
to the provisions of this Article XI, to the payment of amounts payable under
Senior Indebtedness, then the Holders shall be entitled to receive from the
holders of such Senior Indebtedness any payments or distributions received by
such holders of Senior Indebtedness in excess of the amount sufficient to pay
all amounts payable under or in respect of such Senior Indebtedness in full.

          SECTION 5.  Obligations of the Company Unconditional.
                      ---------------------------------------- 

          Nothing contained in this Article XI or elsewhere in this Indenture or
in the Securities is intended to or shall impair as between the Company and the
Holders, the obligation of each such Person, which is absolute and
unconditional, to pay to the Holders the principal of, premium, if any, and
interest on, the Securities as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect the relative
rights of the Holders and creditors of the Company other than the holders of the
Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or
any Holder from exercising all remedies otherwise permitted by applicable law
upon default under this Indenture, subject to the rights, if any, under this
Article XI, of the holders of Senior Indebtedness in respect of cash, property
or securities of the Company received upon the exercise of any such remedy.
Notwithstanding anything to the contrary in this Article XI or elsewhere in this
Indenture or in the Securities, upon any distribution of assets of the Company
referred to in this Article XI, the Trustee, subject to the provisions of
Sections 7.1 and 7.2, and the Holders shall be entitled to rely upon any order
or decree made by any court of competent jurisdiction in which such dissolution,
winding up, liquidation or reorganization proceedings are pending, or a
certificate of the liquidating trustee or agent or other Person making any
distribution to the Trustee or to the Holders for the purpose of ascertaining
the Persons entitled to participate in such distribution, the holders of the
Senior Indebtedness and other Indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article XI so long as such court has been
apprised of the provisions of, or the order, decree or certificate makes
reference to, the provisions of this Article XI.  Nothing in this Section 11.5
shall apply to the claims of,

                                      65

          The Trustee shall not at any time be charged with knowledge of the
existence of any facts which would prohibit the making of any payment to or by
the Trustee unless and until a Trust Officer of the Trustee or any Paying Agent
shall have received, no later than one Business Day prior to such payment,
written notice thereof from the Company or from one or more holders of Senior
Indebtedness or from any representative therefor and, prior to the receipt of
any such written notice, the Trustee, subject to the provisions of Sections 7.1
and 7.2, shall be entitled in all respects conclusively to assume that no such
fact exists.

          SECTION 7.  Application by Trustee of Assets Deposited with It.
                      -------------------------------------------------- 

          Amounts deposited in trust with the Trustee pursuant to and in
accordance with Article VIII shall be for the sole benefit of Securityholders
and, to the extent allocated for the payment of Securities, shall not be subject
to the subordination provisions of this Article XI.  Otherwise, any deposit of
assets with the Trustee or the Agent (whether or not in trust) for the payment
of principal of or interest on any Securities shall be subject to the provisions
of Sections 11.1, 11.2, 11.3 and 11.4; provided that, if prior to one Business
                                       -------- ----                          
Day preceding the date on which by the terms of this Indenture any such assets
may become distributable for any purpose (including, without limitation, the
payment of either principal of or interest on any Security) the Trustee or such
Paying Agent shall not have received with respect to such assets the written
notice provided for in Section 11.6, then the Trustee or such Paying Agent shall
have full power and authority to receive such assets and to apply the same to
the purpose for which they were received, and shall not be affected by any
notice to the contrary which may be received by it on or after such date.

          SECTION 8.  Subordination Rights Not Impaired by Acts or Omissions
                      ------------------------------------------------------
of the Company or Holders of Senior Indebtedness.
- ------------------------------------------------ 

          No right of any present or future holders of any Senior Indebtedness
to enforce subordination provisions contained in this Article XI shall at any
time in any way be prejudiced or impaired by any act or failure to act on the
part of the Company or by any act or failure to act, in good faith, by any such
holder, or by any noncompliance by the Company with the terms of this Indenture,
regardless of any knowledge thereof which any such holder may have or be
otherwise charged with.  The holders of Senior Indebtedness may extend, renew,
modify or amend the terms of the Senior Indebtedness or any security therefor
and release, sell or exchange such security and otherwise deal freely with the
Company, all without affecting the liabilities and obligations of the parties to

                      -----------------------------------------------
Subordination of Securities.

          Each Holder of the Securities by his acceptance thereof authorizes and
expressly directs the Trustee on his behalf to take such action as may be
necessary or appropriate to effectuate the subordination provisions contained in
this Article XI and to protect the rights of the Holders pursuant to this
Indenture, and appoints the Trustee his attorney-in-fact for such purpose,
including, in the event of any dissolution, winding up, liquidation or
reorganization of the Company (whether in bankruptcy, insolvency or receivership
proceedings or upon an assignment for the benefit of creditors of the Company),
the immediate filing of a claim for the unpaid balance of his Securities in the
form required in said proceedings and cause said claim to be approved.  If the
Trustee does not file a proper claim or proof of debt in the form required in
such proceeding prior to 30 days before the expiration of the time to file such
claim or claims, then the holders of the Senior Indebtedness or their
representative are or is hereby authorized to have the right to file and are or
is hereby authorized to file an appropriate claim for and on behalf of the
Holders of said Securities.  Nothing herein contained shall be deemed to
authorize the Trustee or the holders of Senior Indebtedness or their
representative to authorize or consent to or accept or adopt on behalf of any
Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting

                                      67

the Securities or the rights of any Holder thereof, or to authorize the Trustee
or the holders of Senior Indebtedness or their representative to vote in respect
of the claim of any Securityholder in any such proceeding.

          SECTION 10.  Right of Trustee to Hold Senior Indebtedness.

          The Trustee shall be entitled to all of the rights set forth in this
Article XI in respect of any Senior Indebtedness at any time held by it to the
same extent as any other holder of Senior Indebtedness, and nothing in this
Indenture shall be construed to deprive the Trustee of any of its rights as such
holder.

          SECTION 11.  Article XI Not to Prevent Events of Default.
                       ------------------------------------------- 

          The failure to make a payment on account of principal of, premium, if
any, interest on, the Securities by reason of any provision of this Article XI
shall not be construed as preventing the occurrence of a Default or an Event of
Default under Section 6.1 or in any way prevent the Holders from exercising any
right hereunder other than the right to receive payment on the Securities.

          SECTION 12.  No Fiduciary Duty of Trustee to Holders of Senior
                       -------------------------------------------------
Indebtedness.
- ------------ 

          The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Indebtedness, and shall not be liable to any such holders
(other than for its willful misconduct or negligence) if it shall in good faith
mistakenly pay over or distribute to the Holders of Securities or the Company or
any other Person, cash, property or securities to which any holders of Senior
Indebtedness shall be entitled by virtue of this Article XI or otherwise.
Nothing in this Section 11.12 shall affect the obligation of any other such
Person to hold such payment for the benefit of, and to pay such payment over to,
the holders of Senior Indebtedness or their representative.

                           CONVERSION OF SECURITIES

          SECTION 1.  Conversion Privilege.
                      -------------------- 

          Subject to and upon compliance with the provisions of this Article
XII, at the option of the Holder thereof, any Security may at any time be
converted, in whole, or in part in multiples of $1,000 principal amount, into
fully paid and non-assessable shares of Common Stock issuable upon conversion of
the Securities, at the conversion price in effect at the Date of Conversion,
until and including, but not after the close of business on the second Business
Day prior to Stated Maturity, or unless such Security or some portion thereof
shall have been called for redemption or delivered for repurchase prior to such
date and no default is made in making due provision for the payment of the
redemption price in accordance with the terms of this Indenture, in which case,
with respect to such Security or portion thereof as has been so called for
redemption or delivered for repurchase, such Security or portion thereof may be
so converted until and including, but not after, the close of business on the
Business Day prior to the Redemption Date or Repurchase Date, as applicable, for
such Security, unless the Company subsequently fails to pay the applicable
Redemption Price or Repurchase Price, as the case may be.

          SECTION 2.  Exercise of Conversion Privilege.
                      -------------------------------- 

          In order to exercise the conversion privilege, the Holder of any
Security to be converted shall surrender such Security to the Company at any
time during usual business hours at its office or agency maintained for the
purpose as provided in this Indenture, accompanied by a fully executed written
notice, in substantially the form set forth on the reverse of the Security, that
the Holder elects to convert such Security or a stated portion thereof
constituting a multiple of $1,000 principal amount, and, if such Security is
surrendered for conversion during the period between the close of business on
any Record Date and the opening of business on the next following Interest
Payment Date and has not been called for redemption on a Redemption Date which
occurs within such period, accompanied also by payment to the Company of an
amount equal to the interest payable on such Interest Payment Date on the
principal amount of the Security being surrendered for conversion,
notwithstanding

                                      69
<PAGE>
 
such conversion.  The Holder of any Security at the close of business on a
Record Date will be entitled to receive the interest payable on such Security on
the corresponding Interest Payment Date notwithstanding the conversion thereof
after such Record Date.  The interest payment with respect to a Note called for
redemption on a date during the period from the close of business on or after
any Record Date to the close of business on the Business Day following the
corresponding Interest Payment Date will be payable on the corresponding
Interest Payment Date to the registered Holder at the close of business on that
Record Date (not withstanding the conversion of such Note before the
corresponding Interest Payment Date) and a Holder who elects to convert need not
include funds equal to the interest paid.  Such notice of conversion shall also
state the name or names (with address) in which the certificate or certificates
for shares of Common Stock shall be issued.  Securities surrendered for
conversion shall (if reasonably required by the Company or the Trustee) be duly
endorsed by, or be accompanied by a written instrument or instruments of
transfer in form satisfactory to the Company duly executed by, the Holder or his
attorney duly authorized in writing.  As promptly as practicable after the
receipt of such notice and the surrender of such Security as aforesaid, the
Company shall, subject to the provisions of Section 12.8 hereof, issue and
deliver at such office or agency to such Holder, or on his written order, a
certificate or certificates for the number of full shares of Common Stock
issuable on such conversion of Securities in accordance with the provisions of
this Article XII and Cash, as provided in Section 12.3 hereof, in respect of any
fraction of a share of Common Stock otherwise issuable upon such conversion.
Such conversion shall be deemed to have been effected immediately prior to the
close of business on the date (herein called the "Date of Conversion") on which
such Security shall have been surrendered as aforesaid, and the person or
persons in whose name or names any certificate or certificates for shares of
Common Stock shall be issuable upon such conversion shall be deemed to have
become on the Date of Conversion the holder or holders of record of the shares
represented thereby; provided, however, that any such surrender on any date when
                     --------  -------                                          
the stock transfer books of the Company shall be closed shall cause the person
or persons in whose name or names the certificate or certificates for such
shares are to be issued to be deemed to have become the recordholder or holders
thereof for all purposes at the opening of business on the next succeeding day
on which such stock transfer books are

                                      70
<PAGE>
 
open but such conversion shall nevertheless be at the conversion price in effect
at the close of business on the date when such Security shall have been so
surrendered with the conversion notice.  In the case of conversion of a portion,
but less than all, of a Security, the Company shall as promptly as practicable
execute, and the Trustee shall authenticate and deliver to the Holder thereof,
at the expense of the Company, a Security or Securities in the aggregate
principal amount of the unconverted portion of the Security surrendered.  Except
as otherwise expressly provided in this Indenture, no payment or adjustment
shall be made for interest accrued on any Security (or portion thereof)
converted or for dividends or distributions on any Common Stock issued upon
conversion of any Security.

          SECTION 3.  Fractional Interests.
                      -------------------- 

          No fractions of shares or scrip representing fractions of shares shall
be issued upon conversion of Securities.  If more than one Security shall be
surrendered for conversion at one time by the same holder, the number of full
shares which shall be issuable upon conversion thereof shall be computed on the
basis of the aggregate principal amount of the Securities so surrendered.  If
any fraction of a share of Common Stock would, except for the foregoing
provisions of this Section 12.3, be issuable on the conversion of any Security
or Securities, the Company shall make payment in lieu thereof in an amount of
Cash equal to the value of such fraction computed on the basis of the last sale
price of the Common Stock as reported on the New York Stock Exchange (or if not
listed for trading thereon, then on the principal national securities exchange
on which the Common Stock is listed or admitted to trading) at the close of
business on the Date of Conversion or if no such sale takes place on such day,
the last sale price for such day shall be the average of the closing bid and
asked prices regular way on the New York Stock Exchange (or if not listed for
trading thereon, on the principal national securities exchange on which the
Common Stock is listed or admitted to trading) for such day (any such last sale
price being hereinafter referred to as the "Last Sale Price").  If on such
Trading Day the Common Stock is not quoted by any such organization, the fair
value of such Common Stock on such day, as reasonably determined in good faith
by the Board of Directors of the Company, shall be used.

                                      71
<PAGE>
 
          SECTION 4.  Conversion Price.
                      ---------------- 

          The conversion price per share of Common Stock issuable upon
conversion of the Securities shall initially be $[   ] (or $[    ] in principal
amount of Securities for each such share of Common Stock).

          SECTION 5.  Adjustment of Conversion Price.
                      ------------------------------ 

          The conversion price (herein called the "Conversion Price") shall be
subject to adjustment from time to time as follows:

               (a) In case the Company shall (1) make or pay a dividend (or
other distribution) in shares of Common Stock on any class of Capital Stock of
the Company, (2) subdivide its outstanding shares of Common Stock into a greater
number of shares or (3) combine or reclassify its outstanding shares of Common
Stock into a smaller number of shares, the Conversion Price in effect
immediately prior to such action shall be adjusted so that the Holder of any
Security thereafter surrendered for conversion shall be entitled to receive the
number of shares of Common Stock that he would have owned immediately following
such action had such Security been converted immediately prior thereto. An
adjustment made pursuant to this subsection (a) shall become effective
immediately, except as provided in subsection (h) below, after the record date
in the case of a dividend or distribution and shall become effective immediately
after the effective date in the case of a subdivision or combination.

               (b) In case the Company shall issue rights, options or warrants
to all holders of Common Stock entitling them to subscribe for or purchase
shares of Common Stock at a price per share less than the then current market
price per share of the Common Stock (as determined pursuant to subsection (f)
below) on the record date mentioned below, the Conversion Price shall be
adjusted to a price, computed to the nearest cent, so that the same shall equal
the price determined by multiplying:

                    (i) the Conversion Price in effect immediately prior to the
     date of issuance of such rights or warrants by a fraction, of which

                                      72
<PAGE>
 
                    (ii) the numerator shall be (A) the number of shares of
     Common Stock outstanding on the date of issuance of such rights, options or
     warrants, immediately prior to such issuance, plus (B) the number of shares
     which the aggregate offering price of the total number of shares so offered
     for subscription or purchase would purchase at such current market price
     (determined by multiplying such total number of shares by the exercise
     price of such rights, options or warrants and dividing the product so
     obtained by such current market price), and of which

                    (iii) the denominator shall be (A) the number of shares of
     Common Stock outstanding on the date of issuance of such rights, options or
     warrants, immediately prior to such issuance, plus (B) the number of
     additional shares of Common Stock which are so offered for subscription or
     purchase.

          Such adjustment shall become effective immediately, except as provided
in subsection (h) below, after the record date for the determination of holders
entitled to receive such rights, options or warrants; provided, however, that if
                                                      --------  -------         
any such rights, options or warrants issued by the Company as described in this
subsection (b) are only exercisable upon the occurrence of certain triggering
events relating to control and provided for in shareholder rights plans, then
the Conversion Price will not be adjusted as provided in this subsection (b)
until such triggering events occur.

               (c) In case the Company or any Subsidiary of the Company shall
distribute to all holders of Common Stock, any of its assets, evidences of
indebtedness, cash or other assets or shares of Capital Stock other than Common
Stock (including securities, but other than (x) dividends or distributions
exclusively in cash or (y) any dividend or distribution for which an adjustment
is required to be made in accordance with subsection (a) or (b) above), then in
each such case the Conversion Price shall be adjusted so that the same shall
equal the price determined by multiplying the Conversion Price in effect
immediately prior to the date of such distribution by a fraction of which the
numerator shall be the then current market price per share of the Common Stock
(determined as provided in subsection (f) below) on the record date mentioned
below less the then fair market value (as reasonably determined in good faith by
the Board

                                      73
<PAGE>
 
of Directors of the Company) of the portion of the assets so distributed
applicable to one share of Common Stock, and of which the denominator shall be
such current market price per share of the Common Stock.  Such adjustment shall
become effective immediately, except as provided in subsection (h) below, after
the record date for the determination of stockholders entitled to receive such
distribution.  Notwithstanding the foregoing, in the event that the fair market
value of the assets, evidences of indebtedness or other securities so
distributed applicable to one share of Common Stock equals or exceeds such
current market price per share of Common Stock, or such current market price
exceeds such fair market value by less than $0.10 per share, the Conversion
Price shall not be adjusted pursuant to this subsection (c) and, to the extent
applicable, the provisions of subsection (k) shall apply to such distribution.

               (d) In case the Company or any Subsidiary of the Company shall
make any distribution consisting exclusively of cash (excluding any cash portion
of distributions for which an adjustment is required to be made in accordance
with (c) above, or cash distributed upon a merger or consolidation to which
Section 13.6 applies) to all holders of Common Stock in an aggregate amount
that, combined together with (i) all other such all-cash distributions made
within the then preceding 12 months in respect of which no adjustment has been
made and (ii) any cash and the fair market value of other consideration paid or
payable in respect of any tender offer by the Company or any of its Subsidiaries
for Common Stock concluded within the preceding 12 months in respect of which no
adjustment has been made, exceeds 15% of the Company's market capitalization
(defined as being the product of the then current market price of the Common
Stock (determined as provided in subsection (f) below) times the number of
shares of Common Stock then outstanding) on the record date of such
distribution, then in each such case the Conversion Price shall be adjusted so
that the same shall equal the price determined by multiplying the Conversion
Price in effect immediately prior to the date of such distribution by a fraction
of which the numerator shall be the then current market price per share of the
Common Stock on such record date less the amount of the cash so distributed
applicable to one share of Common Stock, and of which the denominator shall be
such current market price per share of the Common Stock. Such adjustment shall
become effective immediately, except as provided in subsection (h) below, after
the record date for the determination of stockholders

                                      74
<PAGE>
 
entitled to receive such distribution.  Notwithstanding the foregoing, in the
event that the cash so distributed applicable to one share of Common Stock
equals or exceeds such current market price per share of Common Stock, or such
current market price exceeds such amount of cash by less than $0.10 per share,
the Conversion Price shall not be adjusted pursuant to this subsection (d).

               (e) In case there shall be completed a tender or exchange offer
made by the Company or any Subsidiary of the Company for all or any portion of
the Common Stock (any such tender or exchange offer being referred to as an
"Offer") that involves an aggregate consideration having a fair market value as
of the expiration of such Offer (the "Expiration Time") that, together with (i)
any cash and the fair market value of any other consideration payable in respect
of any other Offer, as of the expiration of such other Offer, expiring within
the 12 months preceding the expiration of such Offer and in respect for which no
Conversion Price adjustment pursuant to this subsection (e) has been made and
(ii) the aggregate amount of any all-cash distributions referred to in
subsection (d) of this Section 12.5 to all holders of Common Stock within the 12
months preceding the expiration of such Offer for which no conversion price
adjustment pursuant to such subsection (d) has been made, exceeds 15% of the
product of the then current market price per share (determined as provided in
subsection (f) below) of the Common Stock on the Expiration Time times the
number of shares of Common Stock outstanding (including any tendered shares) on
the Expiration Time, the Conversion Price shall be reduced by multiplying such
Conversion Price in effect immediately prior to the Expiration Time by a
fraction of which the numerator shall be (i) the product of the then current
market price per share (determined as provided in subsection (f) below) of the
Common Stock on the Expiration Time times the number of shares of Common Stock
outstanding (including any tendered shares) on the Expiration Time minus (ii)
the fair market value of the aggregate consideration payable to stockholders
based on the acceptance (up to any maximum specified in the terms of the Offer)
of all shares validly tendered and not withdrawn as of the Expiration Time (the
shares deemed so accepted being referred to as the "Purchased Shares") and the
denominator shall be the product of (i) such current market price per share on
the Expiration Time times (ii) such number of outstanding shares on the
Expiration Time less the number of Purchased Shares, such reduction to become
effective immedi-

                                      75
<PAGE>
 
ately prior to the opening of business on the day following the Expiration Time.

          For purposes of this subsection (e), the fair market value of any
consideration with respect to an Offer shall be reasonably determined in good
faith by the Board of Directors of the Company and described in a Board
Resolution.

               (f) For the purpose of any computation under subsections (b),
(c), (d) and (e) above, the current market price per share of Common Stock on
any date shall be deemed to be the average of the Last Sale Prices of a share of
Common Stock for the five consecutive Trading Days selected by the Company
commencing not more than 20 Trading Days before, and ending not later than, the
earlier of the date in question and the date before the "`ex' date," with
respect to the issuance, distribution or Offer requiring such computation. If on
any such Trading Day the Common Stock is not quoted by any organization referred
to in the definition of Last Sale Price in Section 12.3 hereof, the fair value
of the Common Stock on such day, as reasonably determined in good faith by the
Board of Directors of the Company, shall be used. For purposes of this
paragraph, the term "`ex' date," when used with respect to any issuance,
distribution or payments with respect to an Offer, means the first date on which
the Common Stock trades regular way on the New York Stock Exchange (or if not
listed or admitted to trading thereon, then on the principal national securities
exchange on which the Common Stock is listed or admitted to trading) without the
right to receive such issuance, distribution or Offer.

               (g) In addition the foregoing adjustments in subsections (a),
(b), (c), (d) and (e) above, the Company will be permitted to make such
reductions in the Conversion Price as it considers to be advisable in order that
any event treated for Federal income tax purposes as a dividend of stock or
stock rights will not be taxable to the holders of the shares of Common Stock.

          In the event the Company elects to make such a reduction in the
conversion price, the Company will comply with the requirements of Rule 14e-1 of
the Exchange Act and any other Federal and state laws and regulations thereunder
if and to the extent that such laws and regulations are applicable in connection
with the reduction of the Conver-

                                      76
<PAGE>
 
sion Price of the Notes; provided that any provisions of this Indenture which
conflict with such laws shall be deemed to be superseded by the provisions of
such laws.

               (h) In any case in which this Section 12.5 shall require that an
adjustment (including by reason of the last sentence of subsection (a) or (c)
above) be made immediately following a record date, the Company may elect to
defer the effectiveness of such adjustment (but in no event until a date later
than the effective time of the event giving rise to such adjustment), in which
case the Company shall, with respect to any Security converted after such record
date and on and before such adjustment shall have become effective (i) defer
paying any Cash payment pursuant to Section 12.3 hereof or issuing to the Holder
of such Security the number of shares of Common Stock and other Capital Stock of
the Company (or other assets or securities) issuable upon such conversion in
excess of the number of shares of Common Stock and other Capital Stock of the
Company issuable thereupon only on the basis of the Conversion Price prior to
adjustment, and (ii) not later than five Business Days after such adjustment
shall have become effective, pay to such Holder the appropriate Cash payment
pursuant to Section 12.3 hereof and issue to such Holder the additional shares
of Common Stock and other Capital Stock of the Company issuable on such
conversion.

               (i) No adjustment in the Conversion Price shall be required
unless such adjustment would require an increase or decrease of at least 1.0% of
the Conversion Price; provided, that any adjustments which by reason of this
                      --------
subsection (i) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations under this Article
XII shall be made to the nearest cent or to the nearest one-hundredth of a
share, as the case may be.

               (j) Whenever the Conversion Price is adjusted as herein provided,
the Company shall promptly (i) file with the Trustee and each conversion agent
an Officers' Certificate setting forth the Conversion Price after such
adjustment and setting forth a brief statement of the facts requiring such
adjustment, which certificate shall be conclusive evidence of the correctness of
such adjustment, and (ii) mail or cause to be mailed a notice of such adjustment
to each holder of Securities at his address as the same appears on the registry
books of the Company.

                                      77
<PAGE>
 
               (k) In the event that the Company distributes rights or warrants
(other than those referred to in subsection (b) above) pro rata to holders of
Common Stock, so long as any such rights or warrants have not expired or been
redeemed by the Company, the Company shall make proper provision so that the
Holder of any Note surrendered for conversion will be entitled to receive upon
such conversion, in addition to the shares of Common Stock issuable upon such
conversion (the "Conversion Shares"), a number of rights or warrants to be
determined as follows: (i) if such conversion occurs on or prior to the date for
the distribution to the holders of rights or warrants of separate certificates
evidencing such rights or warrants (the "Distribution Date"), the same number of
rights or warrants to which a holder of a number of shares of Common Stock equal
to the number of Conversion Shares is entitled at the time of such conversion in
accordance with the terms and provisions of and applicable to the rights or
warrants, and (ii) if such conversion occurs after such Distribution Date, the
same number of rights or warrants to which a holder of the number of shares of
Common Stock into which the principal amount of such Note so converted was
convertible immediately prior to such Distribution Date would have been entitled
on such Distribution Date in accordance with the terms and provisions of and
applicable to the rights or warrants.

          SECTION 6.  Continuation of Conversion Privilege in Case of
                      -----------------------------------------------
Reclassification, Change, Merger, Consolidation or Sale of Assets.
- ----------------------------------------------------------------- 

          If any of the following shall occur, namely: (a) any reclassification
or change of outstanding shares of Common Stock issuable upon conversion of the
Securities (other than a change in par value, or from par value to no par value,
or from no par value, to par value, or as a result of a subdivision or
combination), (b) any consolidation or merger of the Company with or into any
other Person, or the merger of any other Person with or into the Company (other
than a merger which does not result in any reclassification, change, conversion,
exchange or cancellation of outstanding shares of Common Stock) or (c) any sale,
transfer or conveyance of all or substantially all of the assets of the Company
(computed on a consolidated basis), then the Company, or such successor or
purchasing entity, as the case may be, shall, as a condition precedent to such
reclassification, change, consolidation, merger, sale or conveyance, execute and
deliver to the Trustee a supplemental indenture

                                      78
<PAGE>
 
providing that the Holder of each Security then outstanding shall have the right
to convert such Security only into the kind and amount of shares of stock and
other securities and property (including cash) receivable upon such
reclassification, change, consolidation, merger, sale, transfer or conveyance by
a holder of the number of shares of Common Stock issuable upon conversion of
such Security immediately prior to such reclassification, change, consolidation,
merger, sale, transfer or conveyance assuming such holder of Common Stock of the
Company failed to exercise his rights of an election, if any, as to the kind or
amount of securities, cash and other property receivable upon such
reclassification, change, consolidation, merger, sale, transfer or conveyance
                                                                             
(provided that if the kind or amount of securities, cash, and other property
 --------                                                                   
receivable upon such reclassification, change, consolidation, merger, sale,
transfer or conveyance is not the same for each share of Common Stock of the
Company held immediately prior to such reclassification, change, consolidation,
merger, sale, transfer or conveyance in respect of which such rights of election
shall not have been exercised ("non-electing share"), then for the purpose of
this Section 12.6 the kind and amount of securities, cash and other property
receivable upon such reclassification, change, consolidation, merger, sale,
transfer or conveyance by each non-electing share shall be deemed to be the kind
and amount so receivable per share by a plurality of the non-electing shares).
Such supplemental indenture shall provide for adjustments which shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Article XII.  If, in the case of any such consolidation, merger, sale or
conveyance, the stock or other securities and property (including cash)
receivable thereupon by a holder of shares of Common Stock includes shares of
stock or other securities and property (including cash) of a corporation other
than the successor or purchasing corporation, as the case may be, in such
consolidation, merger, sale or conveyance, then such supplemental indenture
shall also be executed by such other corporation and shall contain such
additional provisions to protect the interests of the Holders of the Securities
as the Board of Directors of the Company shall reasonably consider necessary by
reason of the foregoing.  The provisions of this Section 12.6 shall similarly
apply to successive consolidations, mergers, sales or conveyances.

          Notice of the execution of each such supplemental indenture shall be
mailed to each Holder of Securities at

                                      79
<PAGE>
 
his address as the same appears on the registry books of the Company.

          Neither the Trustee nor any conversion agent shall be under any
responsibility to determine the correctness of any provisions contained in any
such supplemental indenture relating either to the kind or amount of shares of
stock or securities or property (including cash) receivable by Holders of
Securities upon the conversion of their Securities after any such
reclassification, change, consolidation, merger, sale or conveyance or to any
adjustment to be made with respect thereto, but, subject to the provisions of
Article VIII hereof, may accept as conclusive evidence of the correctness of any
such provisions, and shall be protected in relying upon, the Officers'
Certificate (which the Company shall be obligated to file with the Trustee prior
to the execution of any such supplemental indenture) with respect thereto.

          SECTION 7.  Notice of Certain Events.
                      ------------------------ 

          In case:

               (a) the Company shall declare a dividend (or any other
distribution) payable to the holders of Common Stock (other than cash
dividends);

               (b) the Company shall authorize the granting to the holders of
Common Stock of rights, warrants or options to subscribe for or purchase any
shares of stock of any class or of any other rights;

               (c) the Company shall authorize any reclassification or change of
the Common Stock (including a subdivision or combination of its outstanding
shares of Common Stock), or any consolidation or merger to which the Company is
a party and for which approval of any stockholders of the Company is required,
or the sale or conveyance of all or substantially all the property or business
of the Company;

               (d)  there shall be proposed any voluntary or involuntary
dissolution, liquidation or winding-up of the Company; or

               (e)  the Company or any of its Subsidiaries shall complete an
Offer;

                                      80
<PAGE>
 
then, the Company shall cause to be filed at the office or agency maintained for
the purpose of conversion of the Securities as provided in Section 3.2 hereof,
and shall cause to be mailed to each Holder of Securities, at his address as it
shall appear on the registry books of the Company, at least 20 days before the
date hereinafter specified (or the earlier of the dates hereinafter specified,
in the event that more than one date is specified), a notice stating the date on
which (1) a record is expected to be taken for the purpose of such dividend,
distribution, rights, warrants or options or Offer, or if a record is not to be
taken, the date as of which the holders of Common Stock of record to be entitled
to such dividend, distribution, rights, warrants or options or to participate in
such Offer are to be determined, or (2) such reclassification, change,
consolidation, merger, sale, conveyance, dissolution, liquidation or winding-up
is expected to become effective and the date, if any is to be fixed, as of which
it is expected that holders of Common Stock of record shall be entitled to
exchange their shares of Common Stock for securities or other property
deliverable upon such reclassification, change, consolidation, merger, sale,
conveyance, dissolution, liquidation or winding-up.

          SECTION 8.  Taxes on Conversion.
                      ------------------- 

          The Company will pay any and all documentary, stamp or similar taxes
payable to the United States of America or any political subdivision or taxing
authority thereof or therein in respect of the issue or delivery of shares of
Common Stock on conversion of Securities pursuant thereto; provided, however,
                                                           --------  ------- 
that the Company shall not be required to pay any tax which may be payable in
respect of any transfer involved in the issue or delivery of shares of Common
Stock in a name other than that of the Holder of the Securities to be converted
and no such issue or delivery shall be made unless and until the person
requesting such issue or delivery has paid to the Company the amount of any such
tax or has established, to the satisfaction of the Company, that such tax has
been paid.  The Company extends no protection with respect to any other taxes
imposed in connection with conversion of Securities.

                                      81
<PAGE>
 
          SECTION 9.  Company to Provide Stock.
                      ------------------------ 

          The Company shall reserve, free from preemptive rights, out of its
authorized but unissued shares, sufficient shares to provide for the conversion
of the Securities from time to time as such Securities are presented for
conversion, provided, that nothing contained herein shall be construed to
            --------                                                     
preclude the Company from satisfying its obligations in respect of the
conversion of Securities by delivery of repurchased shares of Common Stock which
are held in the treasury of the Company.

          If any shares of Common Stock to be reserved for the purpose of
conversion of Securities hereunder require registration with or approval of any
governmental authority under any Federal or state law before such shares may be
validly issued or delivered upon conversion, then the Company covenants that it
will in good faith and as expeditiously as possible use its best efforts to
secure such registration or approval, as the case may be, provided, however,
                                                          --------  ------- 
that nothing in this Section 12.9 shall be deemed to limit in any way the
obligations of the Company provided in this Article XII.

          Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the Common Stock, the
Company will take all corporate action which may, in the Opinion of Counsel, be
necessary in order that the Company may validly and legally issue fully paid and
non-assessable shares of Common Stock at such adjusted Conversion Price.

          The Company covenants that all shares of Common Stock which may be
issued upon conversion of Securities will upon issue be fully paid and non-
assessable by the Company and free of preemptive rights.

hereof, or with respect to the nature or extent of any such adjustment when
made, or with respect to the method employed, or herein or in any supplemental

ited with the Paying Agent on such Redemption Date and payment of the Securities
called for redemption is not prohibited under Article XI of the Indenture, the
Securities called for redemption will cease to bear interest and the only right
of the Holders of such Securities will be to receive payment of the Redemption
Price, plus any accrued and unpaid interest to the Redemption Date.

7.        Denominations; Transfer; Exchange.
          --------------------------------- 

          The Securities are in registered form, without coupons, in
denominations of $1,000 and integral multiples of $1,000.  A Holder may register
the transfer of, or exchange Securities in accordance with, the Indenture.  The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture.  The Registrar need not register the transfer
of or exchange any Securities selected for redemption.

8.        Persons Deemed Owners.
          --------------------- 

          The registered Holder of a Security may be treated as the owner of it
for all purposes.

9.        Unclaimed Money.
          --------------- 

          If money for the payment of principal or interest  remains unclaimed
for two years, the Trustee and the Paying Agent(s) will pay the money back to
the Company at its written request.  After that, all liability of the Trustee
and such Paying Agent(s) with respect to such money shall cease and the Holder
of such Security shall thereafter look only to the Company for payment of such
money.

10.       Amendment; Supplement; Waiver.
          ----------------------------- 

          Subject to certain exceptions, the Indenture or the Securities may be
amended or supplemented, and any existing Default or Event of Default or
compliance with any provision may be waived, with the written consent of the
Holders of a majority in aggregate principal amount of the Securities then
outstanding.  Without notice to or consent of any Holder, the parties thereto
may amend or supplement the Indenture or the Securities to, among other things,
cure any ambiguity, defect or inconsistency, or make any other

change that does not adversely affect the rights of any Holder of a Security.

11.       Conversion Rights.
          ----------------- 

          Subject to the provisions of the Indenture, the Holders have the right
to convert the principal amount of the Securities into fully paid and
nonassessable shares of Common Stock of the Company at the initial conversion
price per share of Common Stock of $[     ] (or $[     ] in principal amount of
Securities for each such share of Common Stock), or at the adjusted conversion
price then in effect, if adjustment has been made as provided in the Indenture,
upon surrender of the Security to the Company, together with a fully executed
notice in substantially the form attached hereto and, if required by the
Indenture, an amount equal to accrued interest payable on such Security.

12.       Subordination.
          ------------- 

          Payment of principal, premium, if any, and interest on the Securities
is subordinated, in the manner and to the extent set forth in the Indenture, to
the prior payment in full of all Senior Indebtedness.

13.       Repurchase at Option of Holder Upon a Change of Control.
          ------------------------------------------------------- 

          If there is a Change of Control, the Company shall be required to
offer to purchase on the Repurchase Date all outstanding Securities at a
purchase price equal to 100% of the principal amount thereof, plus accrued and
unpaid interest, if any, to the Repurchase Date.  Holders of Securities will
receive a Repurchase Offer from the Company prior to any related Repurchase Date
and may elect to have such Securities purchased by completing the form entitled
"Option of Holder to Elect Purchase" appearing below.

14.       Successors.
          ---------- 

          When a successor assumes all the obligations of its predecessor under
the Securities and the Indenture, the predecessor will be released from those
obligations (except with respect to any obligations that arise from or as a
result of such transaction).

15.       Defaults and Remedies.
          --------------------- 

          If an Event of Default occurs and is continuing (other than an Event
of Default relating to certain events of bankruptcy, insolvency or
reorganization), then in every such case, unless the principal of all of the
securities shall have already become due and payable, either the Trustee or the
Holders of 25% in aggregate principal amount of Securities then outstanding may
declare all the Securities to be due and payable immediately in the manner and
with the effect provided in the Indenture.  Holders of Securities may not
enforce the Indenture or the Securities except as provided in the Indenture.
The Trustee may require indemnity satisfactory to it before it enforces the
Indenture or the Securities.  Subject to certain limitations, Holders of a
majority in aggregate principal amount of the Securities then outstanding may
direct the Trustee in its exercise of any trust or power.  The Trustee may
withhold from Holders of Securities notice of any continuing Default or Event of
Default (except a Default in payment of principal or, interest), if it
determines that withholding notice is in their interest.

16.  Trustee Dealings with Company.
     ----------------------------- 

          The Trustee under the Indenture, in its individual or any other
capacity, may make loans to, accept deposits from, and perform services for the
Company or its Affiliates or any subsidiary of the Company's Affiliates, and may
otherwise deal with the Company or its Affiliates as if it were not the Trustee.

17.       No Recourse Against Others.
          -------------------------- 

          No director or indirect partner, employee, stockholder or officer, as
such, past, present or future, of the Company or any successor corporation or
any Subsidiary or any of the Company's Affiliates shall have any personal
liability in respect of the obligations of the Company under the Securities or
the Indenture by reason of his, her or its status as such partner, stockholder,
director, officer or employee.  Each Holder of a Security by accepting a
Security waives and releases all such liability.  The waiver and release are
part of the consideration for the issuance of the Securities.

          -------------- 

          This Security shall not be valid until the Trustee or authenticating
agent signs the certificate of authentication on the other side of this
Security.

19.       Abbreviations and Defined Terms.

                                           November 20, 1996

United States Filter Corporation
40-004 Cook Street
Palm Desert, California 92211

Ladies and Gentlemen:

     I am Vice President, General Counsel and Secretary of United States Filter
Corporation, a Delaware corporation (the "Company"), and have acted as counsel
to the Company in connection with the Registration Statement on Form S-3 (No.
333-14281), filed by the Company on October 17, 1996, as amended (the
"Registration Statement") with the United States Securities and Exchange
Commission pursuant to the United States Securities Act of 1933, as amended (the
"Act"), with respect to an aggregate of up to $230,000,000 in Convertible
Subordinated Notes due 2001 (the "Notes"), convertible into shares of common
stock of the Company, par value $.01 per share (the "Common Stock").

     I am familiar with the Registration Statement and have reviewed the 
Company's Certificate of Incorporation and By-laws, each as amended and 
restated. I have also examined such other public and corporate documents, 
certificates, instruments and corporate records, and such other questions of 
law, as I have deemed necessary for purposes of expressing an opinion on the 
matters hereinafter set forth. In all examinations of documents, instruments and
other papers, I have assumed the genuineness of all signatures on original and 
certified documents and the conformity to original and certified documents of 
all copies submitted to me as conformed, photostatic or other copies.

     On the basis of the foregoing, I am of the opinion that the issuance of the
Notes and the shares of Common Stock into which the Notes are convertible has 
been duly authorized by the Company, and if and when sold by the Company as 
contemplated by the Prospectus contained in the Registration Statement and, in 
the case of the shares of Common Stock, upon conversion in accordance with the 
terms of the Notes, each will be validly issued, fully paid and non-assessable.

     I hereby consent to the filing of this opinion with the Commission as an
exhibit to the Registration Statement. I also consent to the reference under the
caption "Legal Matters" in the Registration Statement. In giving this consent, I
do not thereby admit that I am included in the category of persons whose consent
is required under Section 7 of the Act or the rules and regulations of the
Commission.

                                       Yours truly,


                                       /s/ Damian C. Georgino
