                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and financial statements, appearing elsewhere in this Prospectus or
incorporated herein by reference. Unless the context otherwise requires, all
references herein to the "Company" and "Culligan" are to Culligan Water
Technologies, Inc., a Delaware corporation, and its consolidated subsidiaries,
and all references herein to "Common Stock" are to the Company's common stock,
par value $.01 per share, and the associated rights described under
"Description of Capital Stock--Stockholder Rights Plan." Unless otherwise
specified, the information in this Prospectus assumes that the over-allotment
options granted to the Underwriters are not exercised.
 
                                  THE COMPANY
 
  Culligan is one of the world's leading manufacturers and distributors of
water purification and treatment products and services for household and
consumer, and commercial and industrial applications. Products and services
offered by the Company range from those designed to solve common residential
water problems, such as filters for tap water and household water softeners, to
highly sophisticated equipment and services, such as ultrafiltration and
microfiltration products, desalination systems and portable deionization
services ("PDS"), designed for complex commercial and industrial applications.
In addition, since the Company entered the five-gallon bottled water market in
1987, Culligan's licensed bottled water sales have grown to rank fifth in the
five-gallon bottled water market in the United States. In mid-1996, Culligan
launched a line of water filtration products for sale through department stores
and do-it-yourself outlets utilizing the WaterWare by Culligan(R) tradename.
 
  Water purification and treatment has developed into a multi-billion dollar
global industry in response to increasingly limited potable water supplies,
global economic expansion, the increasing need for high-quality or ultrapure
water by commercial and industrial companies, heightened public health and
safety concerns relating to drinking water, and the promulgation of numerous
governmental regulations governing water quality. The United States
Environmental Protection Agency's Science Advisory Board, an independent panel
established by Congress, has cited drinking water contamination as one of the
highest ranking environmental risks. In addition, the recently enacted Safe
Drinking Water Act demonstrates a heightened public awareness of the importance
of safe drinking water and a recognition of the need for cost-effective
technological solutions, such as those supplied by Culligan, to protect public
health. The Company believes that it enjoys a competitive advantage in the
water purification and treatment industry based on its widely recognized brand
names, extensive distribution network, technological expertise, broad range of
products and substantial cash flow available for investment, product
development and marketing activities. The Company provides complete solutions
to pre-use water problems through a combination of testing, product selection,
installation, monitoring and service.
 
  The Company has been an active participant in the water purification and
treatment industry since 1936, and its Culligan(R) and Everpure(R) brands,
which are associated with high-quality pure water, are among the most
recognized in the industry. The Company's products are sold and serviced in
over 90 countries through a worldwide network of over 1,400 sales and service
centers. Supporting this distribution network, the Company maintains
manufacturing facilities in the United States, Italy, Spain and Canada. During
the last 15 years, the Company's residential water treatment systems have been
installed in over 2.5 million households in the United States, representing the
largest installed base in the country. In addition, over 1.3 million of the
Company's commercial, industrial, municipal and desalination systems have been
installed worldwide. The Company's customer base includes such

  With net sales of $330.8 million for the twelve months ended July 31, 1996,
the Company is one of the leaders in the highly fragmented water purification
and treatment industry. The Company and its dealers provide a wide range of
services to support its products and offer a full line of accessories and
replacement parts. Approximately 48% of the Company's net sales in fiscal 1996
were derived from sources believed to be recurring in nature, such as servicing
installed equipment, sales of replacement parts, filters and other consumables,
equipment rental and royalties. In fiscal 1996, approximately 40% of the
Company's net sales were from export and international sales. The Company
conducts its activities in two principal areas: (i) household and consumer,
including bottled water, and (ii) commercial and industrial, including portable
deionization services and operate and maintain ("O&M") and build, own and
operate water and wastewater treatment services.
 
                              RECENT DEVELOPMENTS
 
  With the hiring of a new chief executive officer in January 1995 and the
Spin-off of Culligan as an independent company in September 1995, the Company
re-focused on growth. Management's business plan is designed to direct
Culligan's resources towards enhancing the Company's leadership position in a
growing yet fragmented industry. In the twelve months since becoming an
independent public company, Culligan's accomplishments include the following:
 
  STRATEGIC ACQUISITIONS. Made four strategic acquisitions to expand the
Company's existing businesses:
 
  . BRUNER, a manufacturer and distributor of water treatment products
    primarily for commercial and industrial applications, broadening
    Culligan's commercial presence and complementing its existing channels of
    distribution;
 
  . CULLIGAN OPERATING SERVICES, created from the purchase of an O&M business
    for water and wastewater treatment facilities in the southeastern United
    States, establishing Culligan's presence in the wastewater treatment
    market, providing synergies with its existing equipment business, and
    reinforcing Culligan's position as the complete water solutions provider;
 
  . ULTRA PURE SYSTEMS, the owner of proprietary carbon block filter
    technology and a manufacturer of carbon block filters, facilitating the
    launch of Culligan's consumer filter product line and its Water by
    Culligan(R) co-branding strategy;
 
  . ENERSERVE, which builds, owns and operates desalination and other water
    treatment facilities and sells water by the gallon to hotels and
    communities in the Caribbean, furthering Culligan's build, own and
    operate strategy;
 
  DEALER ACQUISITIONS. Instituted a dealer acquisition program designed to
strengthen Culligan's position in major markets. In the last 14 months,
Culligan has acquired five domestic and three European dealers as well as a PDS
business;
 
  CONSUMER PRODUCTS. Launched a line of consumer water filtration products for
sale through department stores and do-it-yourself outlets under the WaterWare
by Culligan(R) brand. The line includes faucet mount filters, under-counter
systems and a whole house sediment and rust filtration system, with products
expected to be available in over 5,000 retail stores by the end of 1997;
 
                                       6
<PAGE>
 
 
  MARKETING PARTNERSHIPS/CO-BRANDING. Entered into a marketing partnership with
Health o Meter, the parent of Mr. Coffee, for co-branded pour through pitchers.
Initiated plans for additional marketing partnerships under which Culligan will
supply filtration elements for refrigerator water/ice dispenser systems,
integral faucet systems, coffee makers and other products, all prominently
displaying the Water by Culligan(R) logo, furthering Culligan's strategy to co-
brand with partners having strong market shares who can offer rapid channel
access with the opportunity to obtain recurring revenues from replacement
filter sales;
 
  INTERNATIONAL EXPANSION. Reorganized international operations, restoring the
division to profitability in fiscal 1996 and enhancing revenue growth, and
expanded Culligan's worldwide reach by signing joint venture agreements or
letters of intent with partners in Australia, India and the Middle East; and
 
  BRAND REINFORCEMENT. Launched, in partnership with Culligan's U.S. dealer
organization, a national television advertising program designed to reinforce
Culligan's position as the preeminent brand name in the water purification and
treatment industry.
 
  These accomplishments, combined with programs to maximize manufacturing
efficiency and service quality, are intended to establish Culligan as the
global water solutions company and are reflected in the Company's recent
financial results. Net sales and adjusted income before interest and taxes
(excluding a gain from an insurance settlement) for the first six months of the
current fiscal year each increased by approximately 17.5% compared to the
comparable period of the prior year. See "Selected Historical and Pro Forma
Financial Data."
 
                               BUSINESS STRATEGY
 
  Consistent with its focus on growth, the Company continues to pursue
expansion of its existing operations as well as growth through acquisitions.
 
 EXPANSION OF EXISTING OPERATIONS
   
  LEVERAGE THE COMPANY'S BRAND NAMES. Culligan(R) is the preeminent brand name
in the water purification and treatment industry. Management plans to continue
to extend its Culligan(R) and Everpure(R) brands to additional product and
market categories. Specifically, Culligan plans to (i) add more products and
outlets to its WaterWare by Culligan(R) consumer line, (ii) seek additional
opportunities for joint marketing efforts in which Culligan can satisfy
filtration needs under its Water by Culligan(R) logo, designed to gain rapid
channel access and recurring revenue, and (iii) market aggressively a full
product and service offering to commercial customers with process water,
foodservice and medical applications. Culligan, in partnership with its
dealers, plans to spend approximately $15 million in the current fiscal year on
advertising to promote its products and reinforce its brand names, up from
$14.1 million spent in its last fiscal year.     
 
  LEVERAGE AND EXPAND THE COMPANY'S DISTRIBUTION NETWORK. Management believes
that additional revenue can be derived from the existing network of Culligan
dealers. Many dealers do not currently offer the Company's complete line of
household, commercial and industrial products, bottled water and PDS. The
Company believes it can facilitate the offering of a more complete line of
products in more territories by providing increased technical support and
customer financing as well as through other joint marketing arrangements with
dealers. The Company also has expanded, and believes it can continue to expand,
its distribution network by extending the coverage of Company-owned dealerships
in selected markets and by converting competitors' dealers to Culligan dealers
in order to penetrate additional territories. The Company believes substantial
opportunity also exists to sell additional products directly through Company-
owned major market dealerships and through complementary channels, utilizing
the nationwide dealer network for installation and ongoing service.
 
 
                                       7
<PAGE>
 
  EUROPEAN GROWTH. The Company plans to broaden its offering of products and
services in the countries it currently serves in Europe. The Company is
actively building its operations in the United Kingdom and Germany to
complement its already strong and growing businesses in France, Italy, Spain
and Belgium. Because of the historical differences in the Company's marketing
focus on a country-by-country basis, management believes it can expand its
European business by aggressively marketing proven products in markets where
they previously were not part of its business emphasis.
 
  INCREASE RESOURCES AVAILABLE TO THE COMMERCIAL AND INDUSTRIAL BUSINESS. The
Company continually seeks to expand its markets by focusing on the evolving
product and application needs of its customers. To support that effort, the
Company has completed recent acquisitions that enhance Culligan's capabilities
in the areas of build, own and operate, bid/job specifications and O&M markets,
complementing Culligan's existing strengths and allowing the Company to offer a
full range of services for process water, foodservice and medical applications.
Further, the Company has increased dealer technical and marketing support.
Culligan believes that its technical, financial and global resources uniquely
position it to provide commercial and industrial customers having small to
medium-sized projects with superior solutions and after-sale support.
 
 GROWTH THROUGH ACQUISITIONS AND JOINT VENTURES
 
  STRATEGIC ACQUISITIONS. The Company is actively pursuing acquisitions in the
fragmented water purification and treatment industry to enhance its portfolio
of products and services, to better utilize its distribution strength and to
take advantage of its vertically integrated structure. The Company's strategy
focuses on adding products, technology, and/or distribution expertise,
consistent with its targeting of the household and consumer market and small
and medium-sized commercial and industrial projects. For example, the Company
recently acquired Ultra Pure Systems, the owner of proprietary carbon block
filter technology and a manufacturer of carbon block filters, which facilitated
the launch of Culligan's consumer filter product line and its Water by
Culligan(R) co-branding strategy.
 
  DEALER PARTNERSHIPS AND ACQUISITIONS. The Company actively seeks to work with
key existing and prospective dealers in an effort to accelerate their growth by
supplying needed capital and expertise and by entering into various joint
marketing and service programs. To supplement its dealer partnership program,
the Company expects to continue to acquire dealerships in major markets to,
among other things, broaden the product lines offered in such markets. The
Company currently owns 34 of its approximately 1,100 dealerships worldwide.
Based on management's estimates that the average dealer has six dollars of
equipment, service and other revenue for every dollar of purchases from the
Company, management believes that dealer partnerships and acquisitions offer
substantial opportunity for growth.
 
  INTERNATIONAL JOINT VENTURES. Culligan's products, technologies and
expertise, including point-of-use filtration technologies and small systems
expertise, are ideally suited to the water treatment needs of developing
nations. The Company plans to enter many such countries in joint ventures with
local partners to accelerate market penetration and take advantage of local
knowledge. For example, the Company has signed a letter of intent for a joint
venture agreement in India with an Indian partner that already has a strong
presence in the water purification and treatment industry; however, no
assurance can be given that such joint venture will be completed.

                                    GENERAL
 
  The Company is a holding company formed in 1993 and conducts all of its
operations through its subsidiaries. In September 1995, the Company's former
parent, Samsonite Corporation ("Samsonite"), previously named Astrum
International Corp. ("Astrum"), distributed to its stockholders all of the
Company's then outstanding common stock (the "Spin-off"). As a result of the
Spin-off, the Company became a separate public company. In the fourth quarter
of fiscal 1996, the Company successfully completed a public offering of
4,025,000 shares of Common Stock.
 
  The Company's executive offices are located at One Culligan Parkway,
Northbrook, Illinois 60062-6209 and its telephone number is (847) 205-6000.

                                 RISK FACTORS
 
  Prospective purchasers of the Common Stock should carefully consider the
risk factors set forth below, as well as the other information contained in
this Prospectus.
 
SIGNIFICANT NON-CASH CHARGES OF THE COMPANY; REPORTED LOSSES
 
  As a result of the emergence from bankruptcy of Astrum, Samsonite's
predecessor, on June 30, 1993, Astrum and all its subsidiaries, including the
Company, were required to adjust their assets and liabilities to reflect their
fair values. The reorganization value in excess of identifiable assets of the
Company, which was $112 million at the time of Astrum's emergence from
bankruptcy, was amortized through charges to the consolidated statement of
operations over a three year period that ended in June 1996. While these
amounts represent non-cash charges, they have had an adverse effect on
reported results of operations in fiscal years 1994, 1995 and 1996 and in the
six months ended July 31, 1996. The losses so reported as a result of the
amortization of these charges have had a similar effect on reported
stockholders' equity. See "Selected Historical and Pro Forma Consolidated
Financial Data."
 
RISKS ASSOCIATED WITH IMPLEMENTING BUSINESS STRATEGY
 
  GENERAL. The Company's business strategy includes initiatives to increase
advertising expenditures, expand its distribution network in both new and
existing markets, expand its direct sales force, develop new products, make
strategic acquisitions of businesses, products and technology, introduce
existing products and technologies into new markets and distribution channels
and introduce new products and services internationally. The Company's
strategic plan should be considered in light of the risks, expenses and
difficulties frequently encountered in growing a business enterprise. The
Company expects to incur significant costs in attempting to implement the
initiatives described above. Successful implementation of those initiatives
will depend on numerous factors, many of which are beyond the Company's
control, including economic, competitive and other conditions and
uncertainties and no assurance can be given that the Company will be
successful in implementing its business strategy. The Company's growth
strategy is expected to require greater capital for its successful execution
than the Company has previously required. There can be no assurance that the
Company will grow as desired. See "Prospectus Summary--Business Strategy."
 
  ACQUISITIONS. The Company's business strategy depends in part on its ability
to effect acquisitions in the fragmented water purification and treatment
industry. The Company continually explores acquisition opportunities; however,
at the present time, the Company has no agreement with respect to any
potential acquisition. The purchase price for potential acquisitions, which
could involve consideration substantially in excess of amounts previously paid
by the Company for acquisitions, may be paid in cash, through the issuance of
Common Stock (which would increase the number of shares of Common Stock
outstanding) or other securities of the Company, borrowings, or a combination
thereof. There can be no assurance that the Company will be able to make
acquisitions on terms favorable to the Company. With respect to recently
completed and potential future acquisitions, the Company may encounter various
associated risks, including the possible inability to integrate an acquired
business into the Company's manufacturing systems, increased goodwill
amortization, increased leverage, diversion of management's attention and
unanticipated problems or liabilities, some or all of which could have a
material adverse effect on the Company's operations and financial performance.
 
RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS
 
  Approximately 40% of the Company's net sales for fiscal 1996 were
attributable to export and international sales. The Company's operations may
be affected by economic, political and governmental conditions in some of the
countries where the Company has manufacturing facilities or where its products
are sold. In addition, changes in economic or political conditions in any of
the countries in which the Company operates could result in unfavorable
exchange rates, new or additional
 
                                      10
<PAGE>
 
currency or exchange controls, other restrictions being imposed on the
operations of the Company or expropriation. The Company's operations also may
be adversely affected by significant fluctuations in the value of the U.S.
dollar and the failure of a partner in an international joint venture to meet
performance expectations. See "Prospectus Summary--Business Strategy" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
COMPETITION
 
  The markets in which the Company competes are highly competitive. The
Company competes with many domestic and international companies in its global
markets. The principal methods of competition in the markets in which the
Company competes are distribution capabilities, product specifications,
product knowledge and reputation, technology, service and price. The Company
has a significant number of competitors, some of which have greater resources
than the Company.
 
TECHNOLOGICAL AND REGULATORY CHANGE
 
  The water purification and treatment industry 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 legislative, regulatory or industrial requirements
may render certain of the Company's purification and 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 and introduce new and enhanced products successfully 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.
 
RESTRICTIVE COVENANTS
 
  The Company's bank credit facility (the "Credit Facility") requires the
Company to achieve and maintain certain financial ratios. In addition, the
Credit Facility contains numerous financial and operating covenants, including
restrictions on the ability of the Company to pay dividends, incur
indebtedness, merge, consolidate or transfer all or substantially all of its
assets, make certain sales of assets, and create, incur or permit the
existence of certain liens. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources." Such financial ratios, restrictions and covenants affect the
operating flexibility of the Company. The failure to maintain the ratios or to
comply with the covenants would result in a default and permit the lenders
under the Credit Facility to accelerate the maturity of the indebtedness
governed by the Credit Facility and related instruments.
 
CONTROLLING STOCKHOLDERS
 
  Prior to giving effect to the Offerings, certain entities affiliated with
Carl C. Icahn (collectively, "Icahn") and affiliates of Apollo Advisors, L.P.
(collectively "Apollo") beneficially own approximately 17.3% and 36.8%,
respectively, of the outstanding Common Stock. Upon completion of the
Offerings, Icahn will no longer beneficially own any shares of Common Stock
and Apollo will own approximately 35.6% of the outstanding Common Stock (34.4%
if the over-allotment options granted to the Underwriters are exercised in
full). By reason of such percentage ownership, Apollo may have significant
control over the management and policies of the Company.
 
                                      11
<PAGE>
 
  The level of ownership of the outstanding Common Stock by the Company's
principal stockholders may have the effect of making more difficult or of
discouraging, absent the support of such stockholders, a proxy contest, a
merger involving the Company, a tender offer, an open market purchase program
or other purchases of the Common Stock that could give holders of such stock
the opportunity to realize a premium over the then-prevailing market price for
their shares of the Common Stock. See "Principal and Selling Stockholders."
 
CERTAIN ANTI-TAKEOVER PROVISIONS
 
  Certain provisions of the Company's Restated Certificate of Incorporation,
Amended and Restated By-Laws and the Company's stockholder rights plan,
together or separately, may discourage potential acquisition proposals, delay
or prevent a change in control of the Company and limit the price that certain
investors might be willing to pay in the future for shares of the Common
Stock. These provisions include a classified board of directors, the ability
to issue, without further stockholder approval, preferred stock with rights
and privileges which would be senior to the Common Stock and advance notice
procedures for stockholders to nominate candidates for election as directors
of the Company and submit proposals for consideration at stockholders'
meetings. See "Description of Capital Stock--Certain Charter and By-Laws
Provisions" and "--Stockholder Rights Plan."
 
SHARES ELIGIBLE FOR FUTURE SALE
 
  No prediction can be made as to the effect, if any, that future sales of
Common Stock, or the availability of Common Stock for future sales, will have
on the market price of the Common Stock prevailing from time to time. Sales in
the public market of substantial amounts of Common Stock (including shares of
Common Stock acquired upon the exercise of options), or the perception that
such sales could occur, could adversely affect prevailing market prices for
the Common Stock. See "Shares Eligible for Future Sale."
 
DIVIDEND POLICY
 
  The Company does not intend to declare any cash dividends on its Common
Stock in the foreseeable future. See "Dividend Policy."
 
                                      12
<PAGE>
 
                                USE OF PROCEEDS
 
  The Company will receive no part of the proceeds from the sale of shares of
Common Stock contemplated hereby, unless the Underwriters' over-allotment
options are exercised. If such over-allotment options are exercised in full,
the Company will receive net proceeds (after payment of the estimated expenses
of the Offerings) of approximately $    million which it will use to repay
indebtedness under the Credit Facility. During the first six months of fiscal
1997, borrowings under the Credit Facility bore interest at a weighted average
interest rate of 6.8% per annum. The Company will bear all expenses incurred
in connection with the Offerings, other than underwriting discounts and
commissions borne by the Selling Stockholders.

  The following table sets forth the Company's capitalization as of July 31,
1996. The information set forth in the table should be read in conjunction

  From the Spin-off until December 15, 1995, there was no established public
trading market for the Common Stock. During such period, approximately 84% of
the Common Stock was held by four beneficial owners and the Common Stock was
not listed on any securities exchange. During that period, the Common Stock
was traded in interdealer and over-the-counter bulletin board transactions.
The range of the bid quotations for the Common Stock from the Spin-off through
December 14, 1995 ranged from a high of $25 per share on December 12, 1995 to
a low of $14 per share on September 28, 1995. Although the quotations for the
period prior to December 15, 1995 have been obtained from sources believed to
be reliable, no assurances can be given with respect to the accuracy of such
quotations or as to whether other bid prices higher or lower than those set
forth above may have been quoted. In addition, such quotations reflect
interdealer prices, which may not include retail mark-up, mark-down or
commission and may not necessarily represent actual transactions.
 
  At August 31, 1996, there were 93 holders of record of the Common Stock.
 
                                DIVIDEND POLICY
 
  The Company has not declared any cash dividends on the Common Stock since
the Spin-off. The Company currently anticipates that it will not pay cash
dividends on shares of the Common Stock in the foreseeable future. The payment
of dividends will be a business decision to be made by the Company's Board of
Directors from time to time based on such considerations as the Board of
Directors deems relevant, will be payable only out of funds legally available
under Delaware law and will be subject to any restrictions which may be
contained in the Company's debt instruments. The payment of cash dividends on
the Common Stock is currently restricted by the Credit Facility. For a
description of dividends paid during periods prior to the Spin-off, see the
Company's Consolidated Financial Statements and notes thereto included in the
Company's Annual Report on Form 10-K for the year ended January 31, 1996. Such
dividends paid prior to the Spin-off are not indicative of the Company's
present or future dividend policy.

         SELECTED HISTORICAL AND PRO FORMA CONSOLIDATED FINANCIAL DATA
 
  The selected historical financial data presented below are derived from the
Company's audited consolidated financial statements. The Company's
consolidated financial statements as of and for the fiscal years ended January
31, 1994, January 31, 1995 and January 31, 1996 have been audited by KPMG Peat
Marwick LLP ("Peat Marwick"), independent auditors. Peat Marwick's report on
the Company's consolidated financial statements for the fiscal year ended
January 31, 1994 contains language that (i) explains the financial statements
for periods subsequent to June 30, 1993 are presented on a different cost
basis than for prior periods and, therefore, are not comparable; and (ii)
highlights changes in methods for accounting for income taxes and post-
retirement benefits other than pensions. The selected historical data as of
and for the six months ended July 31, 1995 and 1996 are unaudited but, in the
opinion of management, include all adjustments (consisting of normal recurring
adjustments) necessary for the fair presentation of the financial data for
such periods.
 
  The selected pro forma statement of operations data for the fiscal year
ended January 31, 1996 give effect to (i) the Company's borrowings under the
Credit Facility during July 1995 that were used to repay an outstanding note
payable to Samsonite (the "Refinancing") and (ii) the public offering of
4,025,000 shares of the Company's Common Stock in the fourth quarter of 1996
(the "Initial Offering"), the proceeds from which were used to repay
borrowings under the Credit Facility, in each case as if they had occurred on
February 1, 1995. The pro forma statement of operations is based on the
audited consolidated financial statements of the Company for the fiscal year
ended January 31, 1996. The pro forma statement of operations is not
necessarily indicative of the results of operations that would have been
reported if such transactions had occurred on the date referred to, nor are
they necessarily indicative of the results of operations to be expected in the
future.
 
  The selected financial information presented below should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the Company's Consolidated Financial Statements
and notes thereto included in the Company's Annual Report on Form 10-K for the
year ended January 31, 1996 which are incorporated by reference herein.

IMPACT OF FAIR VALUE ADJUSTMENTS ATTRIBUTABLE TO THE REORGANIZATION OF ASTRUM
AND ITEMS NOT EXPECTED TO RECUR:
 
  Included in the Reorganized Company's statements of operations subsequent to
June 30, 1993, are amortization and depreciation related to adjustments of
assets and liabilities to fair value in connection with the adoption of the
American Institute of Certified Public Accountants Statement of Position 90-7
entitled "Financial Reporting by Entities in Reorganization under the
Bankruptcy Code" ("SOP 90-7"). The most significant adjustment relates to
reorganization value in excess of identifiable assets which was amortized over
a three year period that ended in June of 1996. In addition, the Reorganized
Company's statement of operations for the six months ended July 31, 1996
includes a gain from an insurance settlement which is not expected to recur.
Due to the significance of these items, and considering that they are either
of a short duration or nonrecurring, management believes that it is useful to
isolate their impact on the statements of operations. The after-tax impact on
net income and the impact on net loss per share are shown below. This
information does not represent and should not be considered an alternative to
net income, any other measure of performance as determined by generally
accepted accounting principles or as an indicator of operating performance.

(a) In June 1993, Samsonite's predecessor, Astrum, completed a financial
    restructuring pursuant to a plan of reorganization under Chapter 11 of the
    United States Bankruptcy Code (the "Plan"). Effective June 30, 1993 and
    pursuant to SOP 90-7, Astrum and all its subsidiaries, including the
    Company, were required to adjust their assets and liabilities to their
    fair ("fresh start") values. Due to the effect of SOP 90-7, Amortization
    of Intangible Assets and Interest Expense (see notes (e) and (h) below)
    for the periods before and after June 30, 1993 are not comparable. The
    information for the "Predecessor Company" reflects activity occurring
    through June 30, 1993, prior to the effectiveness of the Plan and the
    information for the "Reorganized Company" reflects activity occurring
    after such date.
(b) The pro forma statement of operations data for fiscal 1996 gives effect to
    the Refinancing and the Initial Offering, in each case as if they had
    occurred on February 1, 1995. The effects of these transactions are set
    forth below.
  (i) Refinancing: Pro forma interest expense as a result of the Refinancing
      decreased by $1.3 million for fiscal 1996, reflecting the capitalization
      of the Company as a stand alone company and the borrowing under the
      Credit Facility. The interest rate on the borrowing under the Credit
      Facility was assumed to be 8.0% as compared to the interest rate on the
      note payable to Samsonite of 11.5%.
  (ii) Initial Offering: Reflects the sale of 4,025,000 shares of Common Stock
       in the Initial Offering and a reduction in interest expense of $5.9
       million for fiscal 1996, reflecting the repayment of borrowings under
       the Credit Facility with the net proceeds from the Initial Offering and
       the reduction in the assumed interest rate to 6.5% resulting from the
       reduced borrowings. A fluctuation of 1/8% in the interest rate would
       result in a corresponding increase or decrease in interest expense for
       fiscal 1996 of $18,254.
  (iii) Income taxes have been adjusted to reflect the adjustments described
        in (i) and (ii) above.
   
(c) Administrative Expenses Allocated from Samsonite represent certain
    accounting and management services performed for the benefit of the
    Company primarily related to Astrum's reorganization and the Spin-off. In
    prior years, these services were not provided, and are not anticipated to
    recur on an on-going basis.     
(d) The Company implemented a plan to consolidate the production facilities
    and administrative functions of certain operations in Europe. The
    severance, other personnel related costs and facility shut-down expenses
    related to the restructuring resulted in charges in fiscal 1994 and fiscal
    1995 of $2.1 million and $5.9 million, respectively.
(e) Amortization of Intangible Assets consists of the following:

  Property and equipment revalued in connection with the adoption of SOP 90-7
  are being depreciated over their respective estimated useful lives,
  primarily ranging from two to six years.
(g) Other Income (Expense), Net for the six month period ended July 31, 1996
    includes a gain of $1.9 million on an insurance settlement associated with
    a fire at the Company's Belgian facility in July 1993.
(h) Interest Expense for periods subsequent to June 30, 1993 includes interest
    on the $150 million note payable to Samsonite issued in connection with
    Astrum's reorganization. A principal payment of $20 million to Samsonite
    and a $30 million contribution by Samsonite to equity capital of the
    Company on December 1, 1994 and January 31, 1995, respectively, reduced
    the outstanding principal during fiscal 1995. The outstanding balance of
    such note was repaid in full in connection with the Refinancing.
(i) EBITDA is defined as income before interest and taxes, restructuring
    expenses, gain on insurance settlement and administrative expenses
    allocated from Samsonite plus depreciation and amortization. The Company
    believes that EBITDA provides useful information regarding a company's
    financial performance. EBITDA should not be considered in isolation or as
    an alternative to net income, an indicator of the Company's operating
    performance, or an alternative to the Company's cash flow from operating
    activities as a measure of liquidity.

(a) Includes the effects of SOP 90-7 "fresh start" reporting recorded at June
    30, 1993, net of depreciation and amortization. Pursuant to SOP 90-7, the
    net book value of property and equipment was increased by $28 million,
    intangible and other assets were increased by $110 million, and a deferred
    tax liability of $35 million was recorded. In addition, in June 1993, the
    Company issued a subordinated note payable to Samsonite in the amount of
    $150 million.
(b) During fiscal 1996, the Company completed the sale of 4,025,000 shares of
    Common Stock in the Initial Offering. Net proceeds included in equity
    capital at January 31, 1996 are approximately $87 million. The Company
    used such proceeds to repay borrowings under the Credit Facility. Also
    during fiscal 1996, prior to the Spin-off, Samsonite contributed
    approximately $5 million to equity capital of the Company.
(c) Prior to January 25, 1991, all of the Company's domestic cash requirements
    were funded through the centralized cash management system of Samsonite.
    At January 25, 1991, the Company assumed responsibility for its cash
    management and Samsonite transferred $35 million to the Company. As a
    result of this change, cash increased by $32 million and $20 million at
    January 31, 1992 and 1993, respectively. At January 31, 1994, cash
    decreased $91 million primarily as a result of payments of dividends and
    intercompany payables in connection with Astrum's reorganization.
(d) During fiscal 1995, a principal payment of $20 million to Samsonite and a
    $30 million contribution by Samsonite to equity capital of the Company
    were made on December 1, 1994 and January 31, 1995, respectively, related
    to the note payable to Samsonite.
(e) During fiscal 1994, the Company paid dividends to Samsonite of $76
    million. In addition, the effects of "fresh start" reporting recorded at
    June 30, 1993, net of the impact of issuing the $150 million note payable
    to Samsonite, reduced equity capital by approximately $47 million.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion and analysis should be read in conjunction with the
consolidated financial statements and accompanying notes included in the
Company's Annual Report on Form 10-K for the year ended January 31, 1996 filed
with the Securities and Exchange Commission. As a result of the Spin-off, the
Company became a separate public company in September 1995. Following the
Spin-off, the Company completed a public offering of 4,025,000 shares of
Common Stock. The Company's fiscal year ends on January 31. The following
discussion and analysis of results of operations compare (i) the Company's
results of operations for the six months ended July 31, 1996 with the
Company's results of operations for the six months ended July 31, 1995, (ii)
the Company's results of operations for fiscal 1996 with the Company's results
of operations for fiscal 1995, and (iii) the Company's results of operations
for fiscal 1995 with the combined results of operations for the five months
ended June 30, 1993 for the Predecessor Company and the Reorganized Company's
results of operations for the seven months ended January 31, 1994. Due to a
revaluation of assets and liabilities and the adoption of a new basis of
accounting from "fresh start" reporting, the results of operations for periods
subsequent to June 30, 1993 are not comparable to the results of operations
for prior periods.

 SIX MONTHS ENDED JULY 31, 1996 COMPARED TO SIX MONTHS ENDED JULY 31, 1995

for the six months ended July 31, 1995 to $175.3 million for the six months
ended July 31, 1996. Household product sales increased $12.4 million, or
15.3%, primarily due to increased sales at Company-owned dealerships in both
the U.S. and France and the continued demand for the Company's drinking and
bottled water products in the U.S. Approximately $2.0 million of the increase
in household product sales was attributable to the acquisition of retail
dealers made during the last two quarters of fiscal 1996. Commercial and
industrial product sales increased $13.9 million, or 20.2%, primarily due to
acquisitions consummated in the fourth quarter of fiscal 1996 and increased
market penetration in non-U.S. markets.
 
  Gross Profit: Gross profit increased to $78.1 million for the six months
ended July 31, 1996 from $68.3 million in the prior year, an increase of $9.8
million, or 14.3%. Gross profit as a percentage of sales decreased to 44.6%
for the six month period ended July 31, 1996 from 45.8% during the prior
year's comparable period. This decrease resulted from an expected shift in
product mix primarily resulting from the acquisitions of commercial and
industrial product lines completed at the end of fiscal 1996.
 
  Selling, General and Administrative ("SG&A"): As a percentage of sales, SG&A
was 30.9% for the six month period ended July 31, 1996, decreasing, as a
percentage of sales, by 1.7% from the prior year's comparable period. The
improvement was related to continued cost containment initiatives as well as
the impact from acquired businesses which have, after integration, a SG&A
level as a percentage of sales below the Company's historical levels.
 
  Amortization of Intangible Assets: Amortization of intangible assets
decreased by $3.0 million in the six month period of fiscal 1997 from the
prior year's comparable period due to the "Reorganization Value in Excess of
Identifiable Assets" attributable to the Company's former parent, which became
fully amortized in June 1996. This decrease was slightly offset by
amortization related to intangibles recorded in connection with the Company's
acquisitions consummated during the fourth quarter of fiscal 1996.
Amortization of intangible assets related to such "Reorganization Value in
Excess of Identifiable Assets" was $15.6 million in the six months ended July
31, 1996 and $18.7 million in the six months ended July 31, 1995.
 
  Other Income (Expense), Net: In the first six months of fiscal 1997, other
income (expense), net included a gain of $1.9 million from an insurance
settlement related to a fire at the Company's Belgian facility in July 1993.
 
                                      21
<PAGE>
 
  Adjusted Income Before Interest and Taxes: For the six month period ended
July 31, 1996, adjusted income before interest and taxes increased $3.8
million, or 17.4%, to $25.7 million from $21.9 million for the prior year's
comparable period due principally to the reasons described above.
 
  EBITDA: EBITDA as a percentage of sales was 17.1% in each of the six month
periods. Increased sales and the improvement in SG&A as a percentage of sales
were offset by expected decreases in the gross profit percentages.
 
  Interest Income (Expense), Net: Interest expense, net of interest income,
decreased to $1.6 million during the first six months of fiscal 1997 from $6.6
million in the prior year's comparable period due to a reduction in borrowings
resulting from the repayment of debt with proceeds from the Company's equity
offering in the fourth quarter of fiscal 1996 and more favorable interest
rates resulting from the refinancing of debt in July 1995.
 
  Income Taxes: The effective tax rate differs from the statutory rate
primarily because of the nondeductibility of the "Amortization of
Reorganization Value in Excess of Identifiable Assets."
 
 FISCAL 1996 COMPARED TO FISCAL 1995
 
  Net Sales: The Company achieved record sales and earnings in fiscal 1996.
Sales were $304.5 million in fiscal 1996, an increase of $24.4 million or 8.7%
from the fiscal 1995 total of $280.1 million. All business units reported
increased sales, led by household product sales which increased $18.0 million
or 12.4%, largely due to strong sales growth outside the U.S., the inclusion
of the sales of an acquired retail dealer and moderate gains in sales of U.S.
drinking water products. Commercial and industrial product sales improved $6.4
million or 4.8%, as these product categories continued to benefit from
improved business conditions in non-U.S. markets and the continued improvement
domestically by the Company's Everpure subsidiary. Changes in currency
exchange rates had a favorable effect of $6.6 million in the year-to-year
comparison.
 
  Gross Profit: Gross profit increased to $136.1 million in fiscal 1996
compared to $124.2 million in fiscal 1995, a 9.6% improvement. The Company's
gross profit as a percentage of sales improved to 44.7% from 44.3%. The
principal reasons for the improved margins as a percentage of sales were the
mix of products sold internationally, as well as improved profitability
related to commercial and industrial projects, both domestically and
internationally.
 
  Selling, General and Administrative Expenses: As a percentage of sales, SG&A
was 31.4% in fiscal 1996 as compared with 32.8% in fiscal 1995. The
improvement was due to cost and work force reductions internationally,
operational cost improvements domestically and administrative cost containment
initiatives implemented by the Company's new management team.
 
  Restructuring Expenses: The restructuring of the Company's European
manufacturing and distribution operations resulted in charges totaling $5.9
million in fiscal 1995. The charges included severance costs, inventory
writedowns, architectural fees, and one time retention bonuses for key
management employees responsible for carrying out the restructuring. The
remaining restructuring charges to be paid amount to $1.3 million.
 
  Amortization of Intangible Assets: Amortization of intangible assets
increased slightly to $38.8 million in fiscal 1996 from $38.7 million in
fiscal 1995 as a result of amortization related to the intangible assets
recorded in connection with the Company's acquisitions consummated during the
fourth quarter of fiscal 1996. Amortization of intangible assets in fiscal
1996 and fiscal 1995 includes $37.3 million of "Amortization of Reorganization
Value in Excess of Identifiable Assets" resulting from "fresh start"
accounting as required by SOP 90-7.
 
                                      22
<PAGE>
 
  Other Income (Expense), Net: The increase in other income (expense), net in
fiscal 1996 from fiscal 1995 was the result of earnings reported from an
affiliate recorded under the equity method of accounting.
 
  Adjusted Income Before Interest and Taxes: Adjusted income before interest
and taxes increased $10.0 million or 28.8% from $34.7 million in fiscal 1995
to $44.7 million in fiscal 1996 due principally to the reasons described
above.
 
  EBITDA: EBITDA as a percentage of sales increased to 17.3% in fiscal 1996
from 15.0% in fiscal 1995 due primarily to increased sales and an improvement
in gross profit margins and SG&A as a percentage of sales.
 
  Interest Income (Expense), Net: Interest income (expense), net decreased to
$10.9 million in fiscal 1996 from $17.6 million in fiscal 1995 principally as
a result of a reduction in borrowings during the year, and more favorable
interest rates as a result of the Refinancing in July 1995.
 
  Income Taxes: The effective tax rate differs from the statutory rate
primarily because of the nondeductibility of the "Amortization of
Reorganization Value in Excess of Identifiable Assets" and differences in non-
U.S. tax rates.
 
 FISCAL 1995 COMPARED TO COMBINED RESULTS FOR FISCAL 1994
 
  Net Sales: Net sales increased $16.0 million, or 6.1%, from $264.1 million
in fiscal 1994 to $280.1 million in fiscal 1995. Household product sales
increased by $13.5 million, or 10.2%. This increase was due primarily to the
success of continued product promotions and an improvement in both the U.S.
and European economies. Commercial and industrial sales increased $2.5
million, or 1.9%, primarily as a result of strong sales of commercial filter
products, both domestically and in non-U.S. markets, offset, in part, by an
unfavorable foreign exchange impact of $0.6 million.
 
  Gross Profit: Gross profit increased to $124.2 million in fiscal 1995 from
$116.1 million in fiscal 1994, an increase of $8.1 million, or 7.0%. Gross
profit as a percentage of sales increased to 44.3% in fiscal 1995 from 44.0%
in fiscal 1994 principally as a result of a more favorable product mix and
greater utilization of manufacturing capacity. Margins on household products
remained constant year-to-year, while margins on commercial and industrial
products improved slightly due to manufacturing efficiencies.
 
  Selling, General and Administrative Expenses: SG&A expenses as a percentage
of sales remained constant at 32.8%. Increases due to inflation were offset by
the impact of higher sales volumes.
 
  Administrative Expenses Allocated from Samsonite: Administrative expenses
allocated from Samsonite represent certain accounting and management services
performed for the benefit of the Company primarily related to the
reorganization of Astrum and the Spin-off. These services were not provided to
the Company in prior years, and are not expected to recur.
 
  Restructuring Expenses: The severance, other personnel related costs and
facility shut-down expenses related to the European restructuring resulted in
charges in fiscal 1994 and fiscal 1995 of $2.1 million and $5.9 million,
respectively.
 
  Amortization of Intangible Assets: Amortization of intangible assets
increased to $38.7 million in fiscal 1995 from $23.3 million in fiscal 1994
due to the inclusion of a full year of "Amortization of Reorganization Value
in Excess of Identifiable Assets" in fiscal 1995 resulting from "fresh start"
accounting as required by SOP 90-7 as compared to only seven months of such
amortization being included in the prior year.
 
                                      23
<PAGE>
 
  Other Income (Expense), Net: Other income (expense), net decreased to $0.4
million in fiscal 1995 from $1.6 million in fiscal 1994. This decrease was due
to the recognition of a gain from an insurance settlement related to the fire
that destroyed the Company's Belgian plant in fiscal 1994.
 
  Adjusted Income Before Interest and Taxes: Adjusted income before interest
and taxes increased $2.9 million, or 9.1%, from $31.8 million in fiscal 1994
to $34.7 million in fiscal 1995, due primarily to the reasons described above.
 
  EBITDA: EBITDA as a percentage of sales was 15.0% in fiscal 1995, remaining
relatively constant compared to fiscal 1994.
 
  Interest Income (Expense), Net: Interest income decreased to $1.4 million in
fiscal 1995 from $2.3 million in fiscal 1994, a decrease of $0.9 million. This
decrease resulted from reduced available cash due to payments of $93.5 million
to the Company's parent in June 1993 related to Astrum's reorganization.
Interest expense increased to $19.1 million in fiscal 1995 from $12.6 million
in fiscal 1994, an increase of $6.5 million. Fiscal 1995 interest expense
included twelve months of interest on a note due to Samsonite as compared to
only seven months of interest being included in fiscal 1994.
 
  Income Taxes: The effective tax rate differs from the statutory rate
primarily because of the non-deductibility of the "Amortization of
Reorganization Value in Excess of Identifiable Assets."
 
LIQUIDITY AND CAPITAL RESOURCES
 
  The Company's operating cash requirements consist principally of working
capital requirements, scheduled payments of principal on its outstanding
indebtedness and capital expenditures. The Company believes that cash flow
from operating activities and periodic borrowings will be adequate to meet the
Company's operating cash requirements in the future.
 
  Cash provided by operating activities was $13.4 million, $12.4 million and
$13.0 million in fiscal 1996, 1995 and 1994, respectively. The increase in
cash provided by operating activities of $1.0 million in fiscal 1996 was
principally due to improved operating results and reduced interest expense,
offset by increased investments in working capital. In fiscal 1995, cash flows
from operations were adversely impacted from the full year interest expense
relating to a $150 million note payable to Samsonite as compared to only seven
months in fiscal 1994. This adverse impact in fiscal 1995 was offset by
favorable working capital changes. In the six months ended July 31, 1996 cash
provided by operating activities was $1.3 million, an increase of $1.9 million
from the prior year's comparable period resulting from improved operating
results and reduced interest offset by increases in working capital which were
required to fund the higher sales volume and new initiatives such as the
introduction of new consumer products in the current year.
 
  Cash utilized for capital expenditures during the six months ended July 31,
1996 and in fiscal 1996, 1995 and 1994 was $7.4 million, $8.8 million, $10.8
million, and $7.7 million, respectively. During the first six months of fiscal
1997, capital expenditures have increased over historical levels due to
expenditures associated with new dealerships in the U.S. and France and the
expansion of manufacturing operations at the Company's Everpure facility.
Capital expenditures are expected to continue to be made, as required, for the
purpose of maintaining and improving operating facilities and equipment to
increase manufacturing efficiencies and enhance the Company's competitiveness
and profitability on a worldwide basis.
 
  At July 31, 1996, the Company had available credit under the Credit Facility
of $114 million. The Company's Credit Facility is available, among other
things, to finance the working capital needs of the Company, fund standby
letters of credit to support international debt and finance acquisitions.
Loans obtained under the Credit Facility bear interest, at the election of the
Company, at either the bank's
 
                                      24
<PAGE>
 
base rate or a Eurodollar rate, in both cases, together with an applicable
margin based on the consolidated financial performance of the Company.
 
  In the fourth quarter of fiscal 1996, the Company completed a public
offering of 4,025,000 shares of Common Stock, at $23.50 per share, providing
net proceeds of approximately $87 million which were used to repay
indebtedness under the Credit Facility. The offering proceeds have provided
the Company with a capital structure which will enable it to pursue its
acquisition initiatives and strategically compete in the water industry today.
 
  Since the Spin-off, the Company completed several acquisitions of businesses
which complement existing products and operations of the Company. The
aggregate purchase price of approximately $21.6 million, which includes the
assumption of approximately $3.9 million of debt, was financed through
borrowings under the Credit Facility. The Company intends to continue to make
strategic acquisitions as part of its business strategy and presently expects
to finance these activities either by internally generated funds, bank
borrowings, public offerings or private placements of equity or debt
securities, or a combination of the foregoing. No assurance can be given,
however, with respect to the financial or business effect of any possible
future acquisitions.
 
  The Company's principal non-U.S. operations are located in Western Europe,
the economies of which are not considered to be highly inflationary. The
Company's subsidiaries in Spain, Italy and Belgium are subject to currency
fluctuations because these subsidiaries have monetary assets and liabilities
denominated in other than their respective local currencies. It is the
Company's policy not to speculate in non-U.S. currencies, but rather to hedge
against currency changes by using bank borrowings by its non-U.S. subsidiaries
to reduce the extent to which its monetary assets are at risk. From time to
time, the Company has entered into forward exchange contracts in order to
hedge its exposure on certain intercompany transactions. As of July 31, 1996,
the Company had three forward exchange contracts. One of such contracts for $2
million expired in August 1996 and the other two contracts for $4.3 million
expire in July 1997. Net assets of the Company's non-U.S. subsidiaries
translated at July 31, 1996 exchange rates were approximately $41.0 million at
July 31, 1996, an increase of approximately 10% from January 31, 1996.

                                   BUSINESS
 
  The Company serves the household and consumer market, including the bottled
water market, and the commercial and industrial markets, including PDS and
other markets, offering a broad range of products and services. The Company's
product lines include filtration devices, reverse osmosis systems,
desalination facilities, bottled water, water softeners, deionizers and
ultrafiltration products. Product sizes range from small devices for
residential customers to large multi-process systems that are custom
engineered and manufactured for industrial customers. Through its independent
dealers, Company-owned dealers and international distributors, the Company
also offers a full line of accessories, replacement parts and services. In
addition, the Company is a major provider of PDS both domestically and
internationally.
 
  The Company conducts its activities in two principal areas: household and
consumer, including bottled water, and commercial and industrial, including
PDS.
 
  HOUSEHOLD AND CONSUMER. The Company is the leading manufacturer and
distributor of water purification and treatment products to the residential
market in the United States. These products include a broad range of filters,
reverse osmosis units and water softeners that address residential water
problems, including the removal of lead, cysts and other health-related
contaminants, the elimination of chlorine and unpleasant odors and tastes from
water and the softening of water by removing minerals. Culligan's leading
position in the U.S. residential market is due in large part to its product
quality and strong brand recognition, popularized by its famous "Hey Culligan
Man"(R) commercials, as well as its extensive dealer network which is
available for installation and service. Culligan's licensed bottled water
sales have grown to rank fifth in the five-gallon bottled water market in the
United States with an estimated 250,000 accounts and is the only brand in the
five-gallon bottled water business with a nationwide distribution network.
 
  This year, Culligan, through its newly-formed Consumer Markets Division,
launched a line of water filtration products for sale through department
stores and do-it-yourself outlets utilizing the WaterWare by Culligan(R)
tradename. The line includes faucet mount filters, under-counter systems and a
whole house sediment and rust filtration system, with products expected to be
available in over 5,000 retail stores by the end of 1997. This line offers
additional price point alternatives to consumers who are becoming increasingly
aware of, and concerned about, water quality and provides Culligan the
opportunity to leverage its strong brand recognition and to broaden its
customer reach. Culligan has also entered into a marketing partnership with
Health o Meter, the parent of Mr. Coffee, for co-branded pour through
pitchers. The Company has also initiated plans for additional marketing
partnerships under which Culligan will supply filtration elements for
refrigerator water/ice dispenser systems, integral faucet systems, coffee
makers and other products, all prominently displaying the Water by Culligan(R)
logo, furthering Culligan's strategy to co-brand with partners having strong
market shares who can offer rapid channel access with the opportunity to
obtain recurring revenues from replacement filter sales.
 
  In its last fiscal year, household and consumer products and services,
including bottled water royalties, accounted for approximately 54% of the
Company's net sales.
 
  COMMERCIAL AND INDUSTRIAL. Commercial users require water treatment systems
that both remove dissolved minerals and health-related contaminants from the
available water supply and produce large quantities of processed water on a
cost-effective basis. The Company's commercial products are used extensively
in industries where consistently high-quality water is needed to ensure
uniformity of taste, appearance and product quality.
 
  Through its Everpure subsidiary, the Company is the leading supplier of
water filtration products used in the foodservice industry. Currently,
Everpure filtration systems are installed in nearly all McDonald's, Burger
King and Starbucks locations worldwide. Other commercial customers such as
 
                                      26
<PAGE>
 
airlines, hotels, restaurants, office buildings and apartment complexes use
Culligan products to condition, filter, deionize and otherwise treat large
quantities of water.
 
  The Company's industrial treatment systems are custom engineered and combine
multiple processes, including clarification, depth filtration, carbon
filtration, softening, reverse osmosis, deionization, submicron cartridge
filtration and ultraviolet disinfection. These processes can be configured to
meet a wide variety of manufacturing needs and applications. Industrial users
of the Company's products include manufacturers of electronic products,
laboratories, research facilities, food processers, chemical processers,
pharmaceutical manufacturers and printers.
 
  The Company's newly-acquired Bruner operation designs and manufactures water
softeners, filters, deionizers, dealkalizers, demineralizers, degasifiers and
reverse osmosis systems in standard and custom design configurations for
commercial and industrial applications worldwide. Bruner products are sold
through an extensive network of independent sales representatives supported by
sales and service locations in the United States and abroad.
 
  In the commercial and industrial markets, the Company typically targets
small to medium-sized projects, the pricing and specifications of which are
generally based on negotiations with customers rather than on competitive
bidding. These projects can be effectively serviced and supported by the
Company and its worldwide dealer organization.
 
  The Company is one of the leading suppliers of PDS to commercial and
industrial customers in the United States and Europe through its network of
over 380 outlets and approximately 250 regeneration facilities.
 
  The Company also serves the municipal and desalination markets. In the
municipal market, the Company supplies pre-use water treatment equipment to
small community systems. The Company currently has in place in North America,
Europe and the Middle East over 690 pre-engineered, packaged Multi-Tech(R) and
similar Non-U.S. OFSY Omnifiltration(R) systems for small community water
treatment. In addition, the Company's Bruner operation also offers self-
contained Bruner packaged water treatment plants in the municipal market. The
Multi-Tech(R) and Bruner systems are engineered to help smaller communities
meet the requirements of the Safe Drinking Water Act on a cost-effective
basis. Through Culligan Operating Services, the Company also provides O&M
services for water and wastewater treatment facilities for communities and
commercial users primarily in Florida and the Southeastern United States. The
Company has produced major desalination systems throughout the world. The
Company's recently acquired Enerserve operation builds, owns and operates
desalination and other water and wastewater treatment systems in the
Caribbean.
 
  In medical markets, the Company is a leading manufacturer of reverse osmosis
units that comprise an integral part of the kidney dialysis equipment used by
hospitals, hemodialysis centers and other health service providers. The
Company's reverse osmosis unit is one of a limited number of such units
registered by the United States Food and Drug Administration as a medical
device approved for this purpose.
 
  In its last fiscal year, commercial and industrial products, including PDS
and other services, accounted for approximately 46% of the Company's net
sales.
 
  DEALER AND DISTRIBUTION NETWORK. The Company believes that the size and
scope of its dealer and distributor network make it uniquely positioned in the
water purification and treatment industry. Today there are approximately 1,100
independent Culligan dealers and distributors and 34 Company-owned dealers who
distribute and service Culligan products throughout the United States, Canada
and Western Europe as well as other foreign markets. In addition, there are
over 350 distributors and authorized agents in the United States and Western
Europe as well as in other foreign markets that
 
                                      27
<PAGE>
 
distribute water filtration products of the Company's Everpure subsidiary for
the food service industry and other commercial businesses. The Company's
newly-acquired Bruner operation has approximately 97 sales representatives
that distribute its products in the United States and internationally. The
Company believes that this diverse geographical distribution network allows it
to react rapidly to changing customer needs as well as to market conditions.
 
  As part of its distribution system, the Company currently owns 23 Culligan
dealers in North America which had total revenues of approximately $58.8
million in fiscal 1996. The Company-owned dealers are primarily located in
major metropolitan markets. Such markets include the New York City/New Jersey,
Los Angeles, Chicago, Houston and San Francisco metropolitan areas. As part of
its growth strategy, the Company recently acquired dealerships in Dallas,
Texas, San Diego, California, Glendale, California and Elkhart, Indiana to
expand its market presence. In Europe, the Company has 11 Company-owned
dealers principally in France, three of which were acquired in fiscal 1996.
Company-owned dealer operations generally have a high percentage of revenues
which are derived from sources believed to be recurring in nature (estimated
to be approximately 70% of total revenues), such as servicing equipment, sales
of replacement parts, filters and other consumables, equipment rental and
royalties. The Company's dealer and distribution network enables it to offer
complete solutions to pre-use water problems for residential, commercial and
industrial customers through a combination of testing, product selection,
installation, monitoring and service. The Company is continuously upgrading
and expanding its dealer network coverage. The Company also has utilized its
dealer network and distributors to introduce new product lines and enter new
markets.

                         DESCRIPTION OF CAPITAL STOCK
 
AUTHORIZED CAPITAL STOCK
   
  The authorized capital stock of the Company consists of 60,000,000 shares of
Common Stock, par value $.01 per share (the "Common Stock"), and 2,000,000
shares of preferred stock, par value $.01 per share (the "Preferred Stock").
As of the date hereof, there are 19,937,050 shares of Common Stock issued and
outstanding. Although no shares of Preferred Stock have been issued as of the
date hereof, an aggregate of 300,000 shares have been reserved for issuance in
connection with the Company's stockholder rights plan described below under
"Stockholder Rights Plan." The following description of the capital stock of
the Company and of certain provisions of the Company's Restated Certificate of
Incorporation (the "Charter") and the Company's Amended and Restated By-Laws
(the "By-Laws") is a summary of the principal terms thereof. Reference is
hereby made to the full text of the Charter and By-Laws, copies of which are
filed as exhibits to the Registration Statement of which this Prospectus is a
part.     
 
COMMON STOCK
 
  The holders of the Common Stock are entitled to one vote for each share held
of record on all matters submitted to a vote of stockholders. Subject to
preferences that may be applicable to any outstanding Preferred Stock, holders
of Common Stock are entitled to receive ratably such dividends as may from
time to time be declared by the Board of Directors out of funds legally
available therefor. See "Price Range of Common Stock and Dividends." In the
event of a liquidation, dissolution or winding up of the Company, holders of
Common Stock would be entitled to share ratably in all assets of the Company
available for distribution to holders of Common Stock remaining after payment
of liabilities and liquidation preference of any outstanding Preferred Stock.
Holders of Common Stock have no preemptive rights and have no rights to
convert their Common Stock into any other securities and there are no
redemption provisions with respect to such shares. All of the outstanding
shares of Common Stock are fully paid and nonassessable.
 
PREFERRED STOCK
 
  The Board of Directors has the authority to issue the Preferred Stock in one
or more classes or series and to fix the designations, powers, preferences and
rights of the shares of each such class or series, including dividend rates,
conversion rights, voting rights, terms of redemption and liquidation
preferences and the number of shares constituting each such class or series,
without any further vote or action by the stockholders. Although no shares of
Preferred Stock have been issued as of the date hereof, an aggregate of
300,000 shares of junior participating preferred stock have been reserved for
issuance in connection with the stockholder rights plan described below under
"Stockholder Rights Plan." The Company has no other present plans to issue any
shares of the Preferred Stock.
 
TRANSFER AGENT AND REGISTRAR
 
  The Transfer Agent and Registrar for the Common Stock is The First National
Bank of Boston.
 
CERTAIN CHARTER AND BY-LAWS PROVISIONS
 
  The Charter and the By-Laws contain certain provisions that could make more
difficult the acquisition of the Company by means of a tender offer, a proxy
contest or otherwise.
 
  CLASSIFIED BOARD OF DIRECTORS AND RELATED PROVISIONS. The Charter provides
that the Board of Directors shall be divided into three classes, designated
Class I, Class II and Class III, which shall be as nearly equal in number as
possible. Class I directors, who will serve for a term ending with the annual
meeting of stockholders to be held in 1999, currently consists of four
directors, Class II directors, who will serve for a term ending with the
annual meeting of stockholders to be held in 1997,
 
                                      31
<PAGE>
 
consists of four directors and Class III directors, who will serve for a term
ending with the annual meeting of stockholders to be held in 1998, consists of
one director. A director may be removed by the stockholders, but only for
cause, and only by the affirmative vote of the holders, voting as a single
class of a majority of the total number of votes entitled to be cast by all
holders of the voting stock (the "Voting Stock") which shall include the
Common Stock and any class or series of Preferred Stock which by its terms may
be voted on all matters submitted to stockholders of the Company generally.
 
  The purpose of a classified board is to promote conditions of continuity and
stability in the composition of the Board of Directors and in the policies
formulated by the Board of Directors, by guaranteeing that in the ordinary
course at least two-thirds of the directors will at all times have had at
least one year's experience as directors of the Company. However, for similar
reasons, a classified board may deter certain mergers, tender offers or other
takeover attempts which some or a majority of the holders of the Company's
stock may deem to be in their best interest, since it would take two annual
meetings of stockholders to elect a majority of the Board of Directors.
Similarly, a classified board structure would delay stockholders who do not
like the policies of the Board of Directors from removing a majority of the
Board of Directors at a single annual meeting.
 
  ADVANCE NOTICE PROVISIONS FOR STOCKHOLDER NOMINATIONS AND STOCKHOLDER
PROPOSALS. The By-Laws establish an advance notice procedure for stockholders
to make nominations of candidates for election as directors, or bring other
business before an annual meeting of stockholders of the Company (the
"Stockholder Notice Procedure").
 
  The Stockholder Notice Procedure provides that only persons who are
nominated by, or at the direction of, the Company's Board, or by a stockholder
who has given timely written notice to the Secretary of the Company prior to
the meeting at which directors are to be elected, will be eligible for
election as directors of the Company. The Stockholder Notice Procedure
provides that at an annual meeting only such business may be conducted as has
been specified in the notice of the meeting given by or at the direction of
the Company's Board (or any duly authorized committee thereof) or brought
before the meeting by, or at the direction of, the Company's Board (or any
duly authorized committee thereof) or by a stockholder who has given timely
written notice to the Secretary of the Company of such stockholder's intention
to bring such business before such meeting.
 
  Under the Stockholder Notice Procedure, for notice of stockholder
nominations to be made or business to be conducted at an annual meeting to be
timely, such notice must be received by the Company not less than 60 days nor
more than 90 days prior to the date of the annual meeting or, in the event
that less than 70 days notice or prior public disclosure of the date of the
annual meeting is given or made to stockholders, not later than the close of
business on the 10th day following the day on which such notice was mailed or
such public disclosure was made, whichever first occurs. Under the Stockholder
Notice Procedure, for notice of a stockholder nomination to be made at a
special meeting at which directors are to be elected to be timely, such notice
must be received by the Company not later than the close of business on the
10th day following the day on which such notice of the date of the special
meeting was mailed or public disclosure of the date of the special meeting was
made, whichever first occurs.
 
  In addition, under the Stockholder Notice Procedure, a stockholder's notice
to the Company proposing to nominate a person for election as a director or
conduct certain business at an annual meeting must contain certain specified
information. If the Chairman of the Board of Directors presiding at a meeting
determines that a person was not nominated, or other business was not brought
before the meeting, in accordance with the Stockholder Notice Procedure, such
person will not be eligible for election as a director, or such business will
not be conducted at such meeting, as the case may be.
 
STOCKHOLDER RIGHTS PLAN
 
  On September 13, 1996, the Company declared a dividend distribution of one
right (a "Right") for each outstanding share of Common Stock to stockholders
of record at the close of business on
 
                                      32
<PAGE>
 
   
September 26, 1996 (the "Record Date"). Each Right entitles the registered
holder to purchase from the Company one one-hundredth of a share of Series A
Junior Participating Preferred Stock, par value $0.01 per share (the "Series A
Preferred Stock"), at a purchase price of $78, subject to adjustment. The
description and terms of the Rights are set forth in a Rights Agreement (the
"Rights Agreement") between the Company and The First National Bank of Boston,
as Rights Agent.     
 
  Initially, the Rights will be attached to all Common Stock certificates
representing shares then outstanding, and no separate Rights Certificates will
be distributed. The Rights will separate from the Common Stock and a
Distribution Date will occur upon the earlier of (i) ten business days
following a public announcement that a person or group of affiliated or
associated persons (an "Acquiring Person") has acquired beneficial ownership
of 15% or more of the outstanding shares of Common Stock, other than an
Exempted Person (the "Stock Acquisition Date"), or (ii) ten business days (or
such later date as the Board shall determine) following the commencement of a
tender offer or exchange offer that would result in a person or group becoming
an Acquiring Person. "Exempted Person" indicates any person who is the
beneficial owner, on September 3, 1996, of 15% or more of the outstanding
Common Stock and such person's affiliates and associates, provided that such
person, and such person's affiliates and associates, do not increase their
percentage ownership of the Common Stock by more than five percentage points
over their percentage ownership on such date.
 
  Until the Distribution Date, (i) the Rights will be evidenced by the Common
Stock certificates and will be transferred with and only with such Common
Stock certificates, (ii) new Common Stock certificates issued after the Record
Date will contain a notation incorporating the Rights Agreement by reference
and (iii) the surrender for transfer of any certificates for Common Stock
outstanding will also constitute the transfer of the Rights associated with
the Common Stock represented by such certificate. Pursuant to the Rights
Agreement, the Company reserves the right to require prior to the occurrence
of a Triggering Event (as defined below) that, upon any exercise of Rights, a
number of Rights be exercised so that only whole shares of Series A Preferred
Stock will be issued.
 
  The Rights are not exercisable until the Distribution Date and will expire
at the close of business on September 13, 1997, unless earlier redeemed or
extended by the Company as described below.
 
  As soon as practicable after the Distribution Date, Rights Certificates will
be mailed to holders of record of the Common Stock as of the close of business
on the Distribution Date and, thereafter, the separate Rights Certificates
alone will represent the Rights. Except as otherwise determined by the Board,
only shares of Common Stock issued prior to the Distribution Date will be
issued with Rights.
 
  In the event that a person becomes an Acquiring Person (except pursuant to
an offer for all outstanding shares of Common Stock that the disinterested
directors determine not to be inadequate and to otherwise be in the best
interests of the Company and its stockholders), each holder of a Right will
thereafter have the right to receive, upon exercise, Common Stock (or, in
certain circumstances, cash, property or other securities of the Company)
having a value equal to two times the exercise price of the Right.
Notwithstanding any of the foregoing, following the occurrence of the event
set forth in this paragraph, all Rights that are, or (under certain
circumstances specified in the Rights Agreement) were, beneficially owned by
any Acquiring Person will be null and void. However, Rights are not
exercisable following the occurrence of the event set forth above until such
time as the Rights are no longer redeemable by the Company as set forth below.
 
  For example, at an exercise price of $78 per Right, each Right not owned by
an Acquiring Person (or by certain related parties) following an event set
forth in the preceding paragraph would entitle its holder to purchase $156
worth of Common Stock (or other consideration, as noted above) for $78.
Assuming that the Common Stock had a per share value of $39 at such time, the
holder of each valid Right would be entitled to purchase four shares of Common
Stock for $78.
 
  In the event that, at any time following the Stock Acquisition Date, (i) the
Company is acquired in a merger or other business combination transaction
(other than a merger which follows an offer
 
                                      33
<PAGE>
 
described in the second preceding paragraph), or (ii) fifty percent (50%) or
more of the Company's assets, cash flow or earning power is sold or
transferred, each holder of a Right (except Rights which previously have been
voided as set forth above) shall thereafter have the right to receive, upon
exercise, common stock of the acquiring company having a value equal to two
times the exercise price of the Right. The events set forth in this paragraph
and in the second preceding paragraph are referred to as the "Triggering
Events."
 
  At any time until ten business days following the Stock Acquisition Date,
the Company may redeem the Rights in whole, but not in part, at a price of
$.005 per Right (payable in cash, Common Stock or other consideration deemed
appropriate by the Board). Immediately upon the action of the Board ordering
redemption of the Rights, the Rights will terminate and the only right of the
holders of Rights will be to receive the $.005 redemption price.
 
  Until a Right is exercised, the holder thereof, as such, will have no rights
as a stockholder of the Company, including, without limitation, the right to
vote or to receive dividends. While the distribution of the Rights will not be
taxable to stockholders or to the Company, stockholders may, depending upon
the circumstances, recognize taxable income in the event that the Rights
become exercisable for Common Stock (or other consideration) of the Company or
for common stock of the acquiring company as set forth above.
 
  Any of the provisions of the Rights Agreement may be amended by the Board
prior to the Distribution Date. After the Distribution Date, the provisions of
the Rights Agreement may be amended by the Board in order to cure any
ambiguity, to make changes which do not adversely affect the interests of
holders of Rights, or to shorten or lengthen any time period under the Rights
Agreement; provided, however, that no amendment to lengthen a time period
relating to when the Rights may be redeemed may be made at such time as the
Rights are not redeemable.
 
  The Rights have certain anti-takeover effects. The Rights will cause
substantial dilution to a person or group that attempts to acquire the Company
on terms not approved by the Company's Board of Directors. The Rights should
not interfere with any merger or other business combination approved by the
Board since the Rights may be redeemed by the Company at any time until ten
(10) business days following the Stock Acquisition Date.
 
STATUTORY PROVISIONS
 
  Section 203 of the Delaware General Corporation Law (the "GCL") prohibits
certain transactions between a Delaware corporation and an "interested
stockholder," which is defined as a person who, together with any affiliates
and/or associates of such person, beneficially owns, directly or indirectly,
15% or more of the outstanding voting shares of a Delaware corporation. This
provision prohibits certain business combinations (defined broadly to include
mergers, consolidations, sales or other dispositions of assets having an
aggregate value in excess of 10% of the consolidated assets of the
corporation, and certain transactions that would increase the interested
stockholder's proportionate share ownership in the corporation) between an
interested stockholder and a corporation for a period of three years after the
date the interested stockholder acquired its stock, unless (i) the business
combination is approved by the corporation's board of directors prior to the
date the interested stockholder acquired shares, (ii) the interested
stockholder acquired at least 85% of the voting stock of the corporation in
the transaction in which it became an interested stockholder or (iii) the
business combination is approved by a majority of the board of directors and
by the affirmative vote of two-thirds of the votes entitled to be cast by
disinterested stockholders at an annual or special meeting. A Delaware
corporation, pursuant to a provision in its certificate of incorporation or
by-laws, may elect not to be governed by Section 203 of the GCL in which case
such election becomes effective one year after its adoption. In the Charter,
the Company has elected not to be governed by Section 203 of the GCL. Such
election became effective in September 1996.

                        SHARES ELIGIBLE FOR FUTURE SALE
   
  The Company has 19,937,050 shares of Common Stock outstanding on the date of
this Prospectus, all of which will be freely tradeable without restriction or
further registration under the Securities Act, except for any shares held or
purchased by an "affiliate" of the Company as that term is defined in Rule 144
under the Securities Act (an "Affiliate"). Any shares purchased in the
Offerings or otherwise held by an Affiliate of the Company may not be resold
except pursuant to an effective registration statement filed by the Company or
an applicable exemption from registration, including an exemption under Rule
144.     
   
  In general, under Rule 144 as currently in effect, an Affiliate of the
Company is entitled to sell, within any three-month period, a number of shares
of Common Stock that does not exceed the greater of 1% of the then outstanding
shares of the Company's Common Stock (approximately 199,370 shares) or the
average weekly trading volume in the Company's Common Stock during the four
calendar weeks preceding such sale. Sales under Rule 144 are also subject to
certain restrictions on the manner of sale, notice requirements, and the
availability of current public information about the Company.     
 
  In connection with the Spin-off, the Company entered into a registration
rights agreement (the "Registration Rights Agreement") for the benefit of
Apollo and the Selling Stockholders. As of the date of this Prospectus,
approximately 11.7 million shares of outstanding Common Stock constitute
registrable common stock under the Registration Rights Agreement, of which
4,341,253 are being sold pursuant to the Offerings.
 
  Subject to certain exceptions, Apollo (which owns approximately 7.3 million
outstanding shares of Common Stock) has agreed with the Underwriters not to
offer, sell, contract to sell or otherwise dispose of any shares of Common
Stock or any securities convertible into or exercisable or exchangeable for or
warrants, options or rights to acquire, Common Stock, directly or indirectly,
for a period of 90 days after the date of this Prospectus without the prior
written consent of Goldman, Sachs & Co. In addition, the Company will agree
not to effect a registration, without the prior consent of Goldman, Sachs &
Co., with respect to the sale of any shares of Common Stock by any stockholder
of the Company (other than a registration on Form S-8) for a period of 90 days
after the date of this Prospectus.
 
  The Company has filed with the Commission registration statements on Form S-
8 with respect to an aggregate of approximately 2.4 million shares of Common
Stock issuable or reserved for issuance upon exercise of stock options and for
issuance under the Company's Directors' Stock Plan.
 
  No prediction can be made as to the effect, if any, that market sales of
shares of Common Stock or the availability of shares of Common Stock for sale
will have on the market price of the Common Stock prevailing from time to
time. Nevertheless, sales of substantial amounts of the Company's Common Stock
in the public market could adversely affect prevailing market prices of the
Company's Common Stock.

cover page of this Prospectus and in part to certain securities dealers at
such price less a concession of $per share. The U.S. Underwriters may allow,
and such dealers may reallow, a concession not in excess of $per share to
certain brokers and dealers. After the shares of Common Stock are released for
sale to the public, the offering price and the other selling terms may from
time to time be varied by the Representatives.
 
  The Company and the Selling Stockholders have entered into an underwriting
agreement (the "International Underwriting Agreement") with the underwriters
of the international offering (the "International Underwriters") providing for
the concurrent offer and sale of 998,984 shares of Common Stock in an
international offering outside the United States. The offering price and
aggregate underwriting discounts and commissions per share for the two
offerings will be identical. The closing of the offering made hereby is a
condition to the closing of the international offering, and vice versa. The
representatives of the International Underwriters are Goldman Sachs
International, Bear, Stearns International Limited, NatWest Securities
Limited, Smith Barney Inc. and Jefferies International Limited.
 
  Pursuant to an Agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between") relating to the two offerings, each of
the U.S. Underwriters named herein has agreed that, as a part of the
distribution of the shares offered hereby and subject to certain exceptions,
it will offer, sell or deliver the shares of Common Stock, directly or
indirectly, only in the United States
 
                                      36

of America (including the States and the District of Columbia), its
territories, its possessions and other areas subject to its jurisdiction (the
"United States") and to U.S. persons, which term shall mean, for purposes of
this paragraph: (a) any individual who is a resident of the United States or
(b) any corporation, partnership or other entity organized in or under the
laws of the United States or any political subdivision thereof and whose
office most directly involved with the purchase is located in the United
States. Each of the International Underwriters has agreed pursuant to the
Agreement Between that, as a part of the distribution of the shares offered as
part of the international offering and subject to certain exceptions, it will
(i) not, directly or indirectly, offer, sell or deliver shares of Common Stock
(a) in the United States or to any U.S. persons or (b) to any person who it
believes intends to reoffer, resell or deliver the shares in the United States
or to any U.S. persons and (ii) cause any dealer to whom it may sell such
shares at any concession to agree to observe a similar restriction.
 
  Pursuant to the Agreement Between, sales may be made between the U.S.
Underwriters and the International Underwriters of such number of shares of
Common Stock as may be mutually agreed. The price of any shares so sold shall
be the initial public offering price, less an amount not greater than the
selling concession.
 
  The Company has granted the U.S. Underwriters an option exercisable for 30
days after the date of this Prospectus to purchase up to an aggregate of
599,391 additional shares of Common Stock, solely to cover over-allotments, if
any. If the U.S. Underwriters exercise such over-allotment option, the U.S.
Underwriters have severally agreed, subject to certain conditions, to purchase
approximately the same percentage thereof that the number of shares to be
purchased by each of them, as shown in the foregoing table, bears to the
3,995,937 shares of Common Stock offered hereby. The Company has granted the
International Underwriters a similar option to purchase up to an aggregate of
149,848 additional shares of Common Stock.
 
  The Company and Apollo have agreed, for a period of 90 days after the date
of this Prospectus, not to offer, sell, contract to sell or otherwise dispose
of any shares of Common Stock or securities which are substantially similar to
the shares of Common Stock including, but not limited to, securities that are
convertible into or exchangeable for, or that represent the right to receive,
shares of Common Stock or any substantially similar securities without the
prior written consent of Goldman, Sachs & Co., other than (i) pursuant to
employee stock option plans or on the conversion or exchange of convertible or
exchangeable securities or stock options outstanding on the date of this
Prospectus, (ii) the shares of Common Stock offered in connection with the
Offerings, (iii) in the case of the Company, in consideration for
acquisitions, provided that any recipient of Common Stock in such acquisition
agrees to be bound by a restriction not to offer, sell, contract to sell or
otherwise dispose of such shares during the remainder of such 90-day period,
without the prior written consent of Goldman, Sachs & Co. and (iv) in the case
of Apollo, in transactions with an affiliate or not requiring registration
under the Securities Act, provided that in each case any affiliate or
transferee of Common Stock in such transaction agrees to be bound by a
restriction not to offer, sell, contract to sell or otherwise dispose of such
shares during the remainder of such 90-day period, without the prior written
consent of Goldman, Sachs & Co. In addition, the Company has agreed not to
effect a registration with respect to the sale of any shares of Common Stock
by any stockholder of the Company (other than a registration on Form S-8) for
a period of 90 days after the date of this Prospectus without the prior
written consent of Goldman, Sachs & Co.
 
  The Company and the Selling Stockholders have agreed to indemnify the
several U.S. Underwriters and International Underwriters against certain
liabilities, including liabilities under the Securities Act.

                CERTAIN UNITED STATES FEDERAL TAX CONSEQUENCES
                         TO NON-UNITED STATES HOLDERS
 
  The following is a general discussion of certain United States Federal tax
consequences of the acquisition, ownership, and disposition of Common Stock by
a holder that, for United States Federal income tax purposes, is not a "United
States person" (a "Non-United States Holder"). This discussion is based upon
the United States Federal tax law now in effect, which is subject to change,
possibly retroactively. For purposes of this discussion, a "United States
person" means a citizen or resident of the United States; a corporation,
partnership, or other entity created or organized in the United States or
under the laws of the United States or of any political subdivision thereof;
or an estate or trust whose income is includable in gross income for United
States Federal income tax purposes regardless of its source. This discussion
does not consider any specific facts or circumstances that may apply to a
particular Non-United States Holder. Prospective investors are urged to
consult their tax advisors regarding the United States Federal tax
consequences of acquiring, holding, and disposing of Common Stock, as well as
any tax consequences that may arise under the laws of any foreign, state,
local, or other taxing jurisdiction.
 
DIVIDENDS
 
  Dividends paid to a Non-United States Holder will generally be subject to
withholding of United States Federal income tax at the rate of 30% unless the
dividend is effectively connected with the conduct of a trade or business
within the United States by the Non-United States Holder, in which case the
dividend will be subject to United States Federal income tax on net income on
the same basis that applies to United States persons generally. In the case of
a Non-United States Holder which is a corporation, such effectively connected
income also may be subject to the branch profits tax (which is generally
imposed on a foreign corporation on the repatriation from the United States of
effectively connected earnings and profits). Non-United States Holders should
consult any applicable income tax treaties that may provide for a lower rate
of withholding or other rules different from those described above. A Non-
United States Holder may be required to satisfy certain certification
requirements in order to claim treaty benefits or otherwise claim a reduction
of or exemption from withholding under the foregoing rules.
 
GAIN ON DISPOSITION
 
  A Non-United States Holder will generally not be subject to United States
Federal income tax on gain recognized on a sale or other disposition of Common
Stock unless (i) the gain is effectively connected with the conduct of a trade
or business within the United States by the Non-United States Holder, (ii) in
the case of a Non-United States Holder who is a nonresident alien individual
and holds the Common Stock as a capital asset, such holder is present in the
United States for 183 or more days in the taxable year of disposition and
either such individual has a "tax home" in the United States or the gain is
attributable to an office or other fixed place of business maintained by such
individual in the United States or (iii) the Company is or has been a "U.S.
real property holding corporation" for United States Federal income tax
purposes (which the Company does not believe that it is or is likely to
become) and, assuming that the Common Stock is considered to be "regularly
traded on an established securities market" for tax purposes, the Non-United
States Holder holds or has held, directly or indirectly, at any time during
the five-year period ending on the date of disposition, more than five percent
of the Common Stock. Gain that is effectively connected with the conduct of a
trade or business within the United States by the Non-United States Holder
will be subject to United States Federal income tax on net income on the same
basis that applies to United States persons generally (and, with respect to
corporate holders, under certain circumstances, the branch profits tax) but
will not be subject to withholding. Non-United States Holders should consult
any applicable treaties that may provide for different rules.
 
                                      36
<PAGE>
 
PROPOSED REGULATIONS
 
  Recently proposed Treasury regulations (the "Proposed Regulations"), if
finalized in their current form, could affect the procedures to be followed by
a Non-United States Holder in establishing non-United States person status for
purposes of the United States Federal withholding rules. The Proposed
Regulations are not currently effective but, if finalized in their current
form, would be effective for payments made after December 31, 1997.
Prospective investors are urged to consult their tax advisors regarding the
effect, if any, of the Proposed Regulations on their purchase, ownership, and
disposition of the Common Stock.
 
FEDERAL ESTATE TAXES
 
  Common Stock owned or treated as owned by an individual who is not a citizen
or resident of the United States at the date of death will be included in such
individual's estate for United States Federal estate tax purposes, unless an
applicable estate tax treaty provides otherwise.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
  The Company must report annually to the Internal Revenue Service and to each
Non-United States Holder the amount of dividends paid to, and the tax withheld
with respect to, such holder, regardless of whether any tax was actually
withheld. This information may also be made available to the tax authorities
of a country in which the Non-United States Holder resides.
 
  Under temporary United States Treasury regulations, United States
information reporting requirements and backup withholding tax will generally
not apply to dividends paid on the Common Stock to a Non-United States Holder
at an address outside the United States. Payment by a United States office of
a broker of the proceeds of a sale of Common Stock is subject to both backup
withholding at a rate of 31% and information reporting unless the holder
certifies its Non-United States Holder status under penalties of perjury or
otherwise establishes an exemption. Information reporting requirements (but
not backup withholding) will also apply to payment of the proceeds of sales of
Common Stock by foreign offices of United States brokers, or foreign brokers
with certain types of relationships to the United States, unless the broker
has documentary evidence in its records that the holder is a Non-United States
Holder and certain other conditions are met, or the holder otherwise
establishes an exemption.
 
  Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules will be refunded or credited against the Non-United
States Holder's United States Federal income tax liability, provided that the
required information is furnished to the Internal Revenue Service.

</TABLE>
 
  Under the terms and conditions of the International Underwriting Agreement,
the International Underwriters are committed to take and pay for all of the
shares offered hereby, if any are taken.
 
  The International Underwriters propose to offer the shares of Common Stock
in part directly to the public at the initial public offering price set forth
on the cover page of this Prospectus and in part to certain securities dealers
at such price less a concession of $per share. The International Underwriters
may allow, and such dealers may reallow, a concession not in excess of $per
share to certain brokers and dealers. After the shares of Common Stock are
released for sale to the public, the offering price and the other selling
terms may from time to time be varied by the Representatives.
 
  The Company and the Selling Stockholders have entered into an underwriting
agreement (the "U.S. Underwriting Agreement") with the underwriters of the
U.S. offering (the "U.S. Underwriters") providing for the concurrent offer and
sale of 3,995,937 shares of Common Stock in a U.S. offering inside the United
States. The offering price and aggregate underwriting discounts and
commissions per share for the two offerings will be identical. The closing of
the offering made hereby is a condition to the closing of the U.S. offering,
and vice versa. The representatives of the U.S. Underwriters are Goldman,
Sachs & Co., Bear, Stearns & Co. Inc., NatWest Securities Limited, Smith
Barney Inc. and Jefferies & Company, Inc.
 
  Pursuant to an Agreement between the U.S. and International Underwriting
Syndicates (the "Agreement Between") relating to the two offerings, each of
the U.S. Underwriters has agreed that, as a part of the distribution of the
shares offered as a part of the U.S. Offering and subject to certain
 
                                      38

exceptions, it will offer, sell or deliver the shares of Common Stock,
directly or indirectly, only in the United States of America (including the
States and the District of Columbia), its territories, its possessions and
other areas subject to its jurisdiction (the "United States") and to U.S.
persons, which term shall mean, for purposes of this paragraph: (a) any
individual who is a resident of the United States or (b) any corporation,
partnership or other entity organized in or under the laws of the United
States or any political subdivision thereof and whose office most directly
involved with the purchase is located in the United States. Each of the
International Underwriters has agreed pursuant to the Agreement Between that,
as a part of the distribution of the shares offered hereby and subject to
certain exceptions, it will (i) not, directly or indirectly, offer, sell or
deliver shares of Common Stock (a) in the United States or to any U.S. persons
or (b) to any person who it believes intends to reoffer, resell or deliver the
shares in the United States or to any U.S. persons and (ii) cause any dealer
to whom it may sell such shares at any concession to agree to observe a
similar restriction.
 
  Pursuant to the Agreement Between, sales may be made between the U.S.
Underwriters and the International Underwriters of such number of shares of
Common Stock as may be mutually agreed. The price of any shares so sold shall
be the initial public offering price, less an amount not greater than the
selling concession.
 
  The Company has granted the International Underwriters an option exercisable
for 30 days after the date of this Prospectus to purchase up to an aggregate
of 149,848 additional shares of Common Stock, solely to cover over-allotments,
if any. If the International Underwriters exercise such over-allotment option,
the International Underwriters have severally agreed, subject to certain
conditions, to purchase approximately the same percentage thereof that the
number of shares to be purchased by each of them, as shown in the foregoing
table, bears to the 998,984 shares of Common Stock offered hereby. The Company
has granted the U.S. Underwriters a similar option to purchase up to an
aggregate of 599,391 additional shares of Common Stock.
 
  The Company and Apollo have agreed, for a period of 90 days after the date
of this Prospectus, not to offer, sell, contract to sell or otherwise dispose
of any shares of Common Stock or securities which are substantially similar to
the shares of Common Stock including, but not limited to, securities that are
convertible into or exchangeable for, or that represent the right to receive,
shares of Common Stock or any substantially similar securities without the
prior written consent of Goldman, Sachs & Co., other than (i) pursuant to
employee stock option plans or on the conversion or exchange of convertible or
exchangeable securities or stock options outstanding on the date of this
Prospectus, (ii) the shares of Common Stock offered in connection with the
Offerings, (iii) in the case of the Company, in consideration for
acquisitions, provided that any recipient of Common Stock in such acquisition
agrees to be bound by a restriction not to offer, sell, contract to sell or
otherwise dispose of such shares during the remainder of such 90-day period,
without the prior written consent of Goldman, Sachs & Co. and (iv) in the case
of Apollo, in transactions with an affiliate or not requiring registration
under the Securities Act, provided that in each case any affiliate or
transferee of Common Stock in such transaction agrees to be bound by a
restriction not to offer, sell, contract to sell or otherwise dispose of such
shares during the remainder of such 90-day period, without the prior written
consent of Goldman, Sachs & Co. In addition, the Company has agreed not to
effect a registration with respect to the sale of any shares of Common Stock
by any stockholder of the Company (other than a registration on Form S-8) for
a period of 90 days after the date of this Prospectus without the prior
written consent of Goldman, Sachs & Co.
 
  Each International Underwriter has also agreed that (a) it has not offered
or sold and prior to the date six months after the date of issue of the shares
of Common Stock will not offer or sell any shares of Common Stock to persons
in the United Kingdom except to persons whose ordinary activities involve them
in acquiring, holding, managing or disposing of investments (as principal or
agent) for the purposes of their businesses or otherwise in circumstances
which have not resulted and will not result
 
                                      39
<PAGE>
 
in an offer to the public in the United Kingdom within the meaning of the
Public Offers of Securities Regulations 1995, (b) it has complied, and will
comply, with all applicable provisions of the Financial Services Act of 1986
of Great Britain with respect to anything done by it in relation to the shares
of Common Stock in, from or otherwise involving the United Kingdom, and (c) it
has only issued or passed on and will only issue or pass on in the United
Kingdom any document received by it in connection with the issuance of the
shares of Common Stock to a person whose is of a kind described in Article
11(3) of the Financial Services Act 1986 (Investment Advertisements)
(Exemptions) Order 1996 of Great Britain or is a person to whom the document
may otherwise lawfully be issued or passed on.
 
  Buyers of shares of Common Stock offered hereby may be required to pay stamp
taxes and other charges in accordance with the laws and practice of the
country of purchase in addition to the initial public offering price.
 
  The Company and the Selling Stockholders have agreed to indemnify the
several International Underwriters and U.S. Underwriters against certain
liabilities, including liabilities under the Securities Act.
 
                                 LEGAL MATTERS
 
  Certain legal matters with respect to the Common Stock have been passed upon
for the Company by Skadden, Arps, Slate, Meagher & Flom, New York, New York,
and for the Underwriters by Sidley & Austin, Chicago, Illinois. Skadden, Arps,
Slate, Meagher & Flom, has from time to time represented certain of the
Underwriters in connection with unrelated legal matters.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Section 145 of the Delaware General Corporation Law (the "GCL") empowers a
corporation, subject to certain limitations, to indemnify its directors and
officers against expenses (including attorneys' fees, judgments, fines and
certain settlements) actually and reasonably incurred by them in connection
with any suit or proceeding to which they are a party so long as they acted in
good faith and in a manner reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to criminal action or
proceeding, so long as they had no reasonable cause to believe their conduct
to have been unlawful.
 
  The Charter provides that the Company shall indemnify the directors and
officers of the Company to the fullest extent permitted by Delaware law.
 
  In addition, the By-Laws provide that the Company shall indemnify any person
who was or is a party or is threatened to be made a party to any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of
the Company), by reason of the fact that he is or was a director or officer of
the Company, or is or was serving at the request of the Company as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding
if he acted in good faith and in a manner which he reasonably believed to be
in or not opposed to the best interests of the Company and, with respect to
any criminal action or proceeding, had no reasonable cause to believe his
conduct was unlawful. The termination of any action, suit or proceeding by
judgment, order, settlement, conviction or upon a plea of nolo contendere or
its equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which he reasonably believed to be in or
not opposed to the best interests of the Company and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his
conduct was unlawful.
 
  The By-Laws provide that the Company shall indemnify any person who was or
is a party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the Company to procure a
judgment in its favor by reason of the fact that he is or was a director or
officer of the Company or is or was serving at the request of the Company as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or
 
                                     II-1
<PAGE>
 
other enterprise against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection with the defense or settlement of
such action or suit if he acted in good faith and in a manner he reasonably
believed to be in or not opposed to the best interests of the Company; except
that no indemnification shall be made in respect of any claim, issue or matter
as to which such person shall have been adjudged to be liable to the Company
unless and only to the extent that the Court of Chancery of the State of
Delaware or the court in which such action or suit was brought shall determine
upon application that, despite the adjudication of liability but in view of
all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery of the
State of Delaware or such other court shall deem proper.
 
  The By-Laws provide that any indemnification under the above two paragraphs
(unless ordered by a court) shall be made by the Company only as authorized in
the specific case upon a determination that indemnification of the director,
officer, employee or agent is proper in the circumstances because he has met
the applicable standard of conduct set forth in the above two paragraphs. Such
determination shall be made (1) by the Board of Directors of the Company by a
majority vote of a quorum consisting of directors who were not parties to such
action, suit or proceeding, even though less than a quorum or (2) if there are
such directors or if such directors so direct, by independent legal counsel in
a written opinion, or (3) by the stockholders of the Company.
 
  The By-Laws provide that to the extent that a director or officer of the
Company has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to above, or in defense of any claim,
issue or matter therein, the Company shall indemnify him against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.
 
  The By-Laws further provide that expenses incurred by a director or officer
in defending or investigating a threatened or pending action, suit or
proceeding shall be paid by the Company in advance of the final disposition of
such action, suit or proceeding upon receipt of an undertaking by or on behalf
of the director or officer to repay such amount if it shall ultimately be
determined that he is not entitled to be indemnified by the Company as
authorized in the By-Laws. Such expenses incurred by other employees and
agents may be so paid upon such terms and conditions, if any, as the Board of
Directors of the Company deems appropriate.
 
  The By-Laws provide that the indemnification and advancement of expenses
provided by, or granted pursuant to, the By-Laws shall not be deemed exclusive
of any other rights to which those seeking indemnification or advancement of
expenses may be entitled under any by-law, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official
capacity and as to action in another capacity while holding such office.
 
  The Company intends to purchase and maintain insurance on behalf of any
person who is or was a director or officer of the Company, or is or was a
director or officer of the Company serving at the request of the Company as a
director, officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise against any
liability asserted against him and incurred by him in any such capacity, or
arising out of his status as such, whether or not the Company would have the
power or the obligation to indemnify him against such liability under the By-
Laws.
 
  The Company has entered into indemnification agreements with each of the
Company's directors and officers. The indemnification agreements require,
among other things, the Company to indemnify the officers and directors to the
fullest extent permitted by law, and to advance to such directors and officers
all related expenses, subject to reimbursement, if it is subsequently
determined that indemnification is not permitted. The Company will also
indemnify and advance all expenses incurred by such directors and officers
seeking to enforce their rights under the indemnification agreements, and
cover directors and officers under the Company's directors' and officers'
liability insurance.
 
                                     II-2
<PAGE>
 
Although such indemnification agreements will offer substantially the same
scope of coverage afforded by provisions in the Charter and the By-Laws, they
provide greater assurance to directors and officers that indemnification will
be available because, as a contract, it cannot be modified unilaterally in the
future by the Board of Directors of the Company or by the stockholders to
eliminate the rights provided therein.

ITEM 17. UNDERTAKINGS
 
  (a) 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 Common Stock 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.
 
  (b) The undersigned registrant hereby undertakes that:
 
    (1) For purposes 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.
 
    (3) For purposes of determining any liability under the Securities Act,
  each filing of the Registrant's annual report pursuant to Section 13(a) or
  15(d) of the Exchange Act (and where applicable, each filing of an employee
  benefit plan's annual report pursuant to Section 15(d) of the Exchange Act)
  that is incorporated by reference in the Registration Statement shall be
  deemed to be 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.

  As representatives of the several Underwriters
    named in Schedule I hereto,
c/o Goldman, Sachs & Co.
85 Broad Street,
New York, New York 10004.

Ladies and Gentlemen:

     Certain stockholders named in Schedule II hereto (the "Selling
Stockholders") of Culligan Water Technologies, Inc., a Delaware corporation (the
"Company"), propose, subject to the terms and conditions stated herein, to sell
to the Underwriters named in Schedule I hereto (the "Underwriters") an aggregate
of 3,995,937 shares (the "Firm Shares") and, at the election of the
Underwriters, the Company proposes to issue and sell up to 599,391 additional
shares (the "Optional Shares") of Common Stock, par value $.01 per share
("Stock") of the Company (the Firm Shares and the Optional Shares that the
Underwriters elect to purchase pursuant to Section 2 hereof being collectively
called the "Shares").

     It is understood and agreed to by all parties that the Company and the
Selling Stockholders are concurrently entering into an agreement (the
"International Underwriting Agreement") providing for the sale by the Company
and the Selling Stockholders of up to a total of 1,148,832 shares of Stock (the
"International Shares"), including the overallotment option thereunder, through
arrangements with certain underwriters outside the United States (the
"International Underwriters"), for whom Goldman Sachs International, Bear,
Stearns International Limited, NatWest Securities Limited, Smith Barney Inc. and
Jefferies International Limited are acting as lead managers. Anything herein or
therein to the contrary notwithstanding, the respective closings under this
Agreement and the International Agreement are hereby expressly made conditional
on one another. The Underwriters hereunder and the International Underwriters
are simultaneously entering into an Agreement between U.S. and International
Underwriting Syndicates (the "Agreement between Syndicates") which provides,
among other things, for the transfer of shares of Stock between the two
syndicates. Two forms of prospectus are to be used in connection with the
offering and sale of shares of Stock contemplated by the foregoing, one relating
to the Shares hereunder and the other relating to the International Shares. The
latter form of prospectus will be identical to the former except for certain
substitute pages as included in the registration statement and amendments
thereto as mentioned below. Except as used in Sections 2, 3, 4, 9 and 11 herein,
and except as the context may otherwise require, references hereinafter to the
Shares shall include all the shares of Stock which may be sold
<PAGE>
 
pursuant to either this Agreement or the International Underwriting Agreement,
and references herein to any prospectus whether in preliminary or final form,
and whether as amended or supplemented, shall include both the U.S. and the
international versions thereof.

     1.   (a)  The Company represents and warrants to, and agrees with, each of
the Underwriters that:

          (i) A registration statement on Form S-3 (File No. 333-12069) (the
     "Initial Registration Statement") in respect of the Shares has been filed
     with the Securities and Exchange Commission (the "Commission"); the Initial
     Registration Statement and any post-effective amendment thereto, each in
     the form heretofore delivered to you, and, excluding exhibits thereto, but
     including all documents incorporated by reference in the prospectus
     contained therein, to you for each of the other Underwriters, have been
     declared effective by the Commission in such form; other than a
     registration statement, if any, increasing the size of the offering (a
     "Rule 462(b) Registration Statement"), filed pursuant to Rule 462(b) under
     the Securities Act of 1933, as amended (the "Act"), which became effective
     upon filing, no other document with respect to the Initial Registration
     Statement or other document incorporated by reference therein has
     heretofore been filed with the Commission; and no stop order suspending the
     effectiveness of the Initial Registration Statement, any post-effective
     amendment thereto or Rule 462(b) Registration Statement, if any, has been
     issued and no proceeding for that purpose has been initiated or threatened
     by the Commission (any preliminary prospectus included in the Initial
     Registration Statement or filed with the Commission pursuant to Rule 424(a)
     of the rules and regulations of the Commission under the Act is hereinafter
     called a "Preliminary Prospectus"); the various parts of the Initial
     Registration Statement and the Rule 462(b) Registration Statement, if any,
     including all exhibits thereto and including (i) the information contained
     in the form of final prospectus filed with the Commission pursuant to Rule
     424(b) under the Act in accordance with Section 5(a) hereof and deemed by
     virtue of Rule 430A under the Act to be part of the Initial Registration
     Statement at the time it was declared effective and (ii) the documents
     incorporated by reference in the prospectus contained in the registration
     statement at the time such part of the registration statement became
     effective, each as amended at the time such part of the Initial
     Registration Statement became effective or such part of the Rule 462(b)
     Registration Statement, if any, became or hereafter becomes effective, are
     hereinafter collectively called the "Registration Statement"; such final
     prospectus, in the form first filed pursuant to Rule 424(b) under the Act,
     is hereinafter called the "Prospectus"; and any reference herein to any
     Preliminary Prospectus or the Prospectus shall be deemed to refer to and
     include the documents incorporated by reference therein pursuant to Item 12
     of Form S-3 under the Act, as of the date of such Preliminary Prospectus or
     Prospectus, as the case may be; any reference to any amendment or
     supplement to any Preliminary Prospectus or the Prospectus shall be deemed

     the effective date of the Registration Statement that is incorporated by
     reference in the Registration Statement;

     Prospectus has been issued by the Commission, and each Preliminary

     not apply to any statements or omissions made in reliance upon and in
     conformity with information furnished in writing to the Company by an

     or the Exchange Act, as applicable, and the rules and regulations of the

     to be stated therein or necessary to make the statements therein not
     misleading; and any further documents so filed and incorporated by

     the Act and the rules and regulations of the Commission thereunder and do
     not and will not, as of the applicable effective date as to the
     Registration Statement and any amendment thereto and as of the applicable
     filing date as to the Prospectus and any amendment or supplement thereto,
     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 not misleading; provided, however, that this representation and
     warranty shall not apply to any statements or omissions made in reliance
     upon and in conformity with information furnished in writing to the Company

     Shares, if not the First Time of Delivery, is herein called the "Second
     Time of Delivery", and each such time and date for delivery is herein

as to ownership of, and liens, encumbrances, equities or claims on the Shares
sold by such Selling Stockholder, provided that such counsel shall state that
they believe that both you and they are justified in relying upon such
certificate.

          (e) On the date of the Prospectus at a time prior to the execution of
     this Agreement, at 9:30 a.m., New York City time, on the effective date of
     any post-effective amendment to the Registration Statement filed subsequent
     to the date of this Agreement and also at each Time of Delivery, KPMG Peat
     Marwick LLP shall have furnished to you a letter or letters, dated the
     respective dates of delivery thereof, in form and substance satisfactory to
     you, to the effect set forth in Annex IV hereto;

          (f)(i) Neither the Company nor any of its subsidiaries shall have
     sustained since the date of the latest audited financial statements
     included or incorporated by reference in the Prospectus any loss or
     interference with its business from fire, explosion, flood or other
     calamity, whether or not covered by insurance, or from any labor dispute or
     court or governmental action, order or decree, otherwise than as set forth
     or contemplated in the Prospectus, and (ii) since the respective dates as
     of which information is given in the Prospectus there shall not have been
     any change in the amount of issued and outstanding capital stock (other
     than upon exercise of stock options outstanding as of such dates) or long-
     term debt of the Company or any of its subsidiaries, other than borrowings
     by the Company not in excess of $__ million in the aggregate, or any
     change, or any development involving a prospective change, in or affecting
     the general affairs, management, financial position, stockholders' equity
     or results of operations of the Company and its subsidiaries, otherwise
     than as set forth or contemplated in the Prospectus, the effect of which,
     in any such case described in Clause (i) or (ii), is in the judgment of the
     Representatives so material and adverse as to make it impracticable or
     inadvisable to proceed with the public offering or the delivery of the
     Shares being delivered at such Time of Delivery on the terms and in the
     manner contemplated in the Prospectus;

          (g) On or after the date hereof there shall not have occurred any of
     the following: (i) a suspension or material limitation in trading in
     securities generally on the Exchange; (ii) a suspension or material
     limitation in trading in the Company's securities on the Exchange; (iii) a
     general moratorium on commercial banking activities declared by either
     Federal, New York or Illinois State authorities; or (iv) the outbreak or
     escalation of hostilities involving the United States or the declaration by
     the United States of a national emergency or war, if the effect of any such
     event specified in this Clause (iv) in the judgment of the Representatives
     makes it impracticable or inadvisable to proceed with the public offering
     or the delivery of the Shares being delivered at such Time of Delivery on
     the terms and in the manner contemplated in the Prospectus;

          (h) The Shares to be sold at such Time of Delivery shall have been
     duly listed, subject to notice of issuance, on the Exchange;

          (i) The Company has obtained and delivered to the Underwriters
     executed copies of an agreement from each of Apollo Investment Fund, L.P.
     and Lion Advisors, L.P. substantially to the effect set forth in Subsection
     5(e) hereof in form and substance satisfactory to you;

          (j) The Company shall have complied with the provisions of Section
     5(c) hereof with respect to the furnishing of prospectuses on the New York
     Business Day next succeeding the date of this Agreement; and

                                      14

<PAGE>
 
          (k) The Company and the Selling Stockholders shall have furnished or
     caused to be furnished to you at such Time of Delivery certificates of
     officers of the Company and the Selling Stockholders, respectively,
     satisfactory to you as to the accuracy of the representations and
     warranties of the Company and the Selling Stockholders, respectively,
     herein at and as of such Time of Delivery, and as to the performance by the
     Company and the Selling Stockholders of all of their respective obligations
     hereunder to be performed at or prior to such Time of Delivery, as to the
     matters set forth in subsections (a) and (f) of this Section and as to such
     other matters as you may reasonably request in connection with the delivery
     of the Shares hereunder.

8.        (a)  The Company will indemnify and hold harmless each Underwriter
     against any losses, claims, damages or liabilities, joint or several, to
     which such Underwriter may become subject, under the Act or otherwise,
     insofar as such losses, claims, damages or liabilities (or actions in
     respect thereof) arise out of or are based upon an untrue statement or
     alleged untrue statement of a material fact contained in any Preliminary
     Prospectus, the Registration Statement or the Prospectus, or any amendment
     or supplement thereto, or arise out of or are based upon the omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading, and
     will reimburse each Underwriter for any legal or other expenses reasonably
     incurred by such Underwriter in connection with investigating or defending
     any such action or claim as such expenses are incurred; provided, however,
     that the Company shall not be liable in any such case to the extent that
     any such loss, claim, damage or liability arises out of or is based upon an
     untrue statement or alleged untrue statement or omission or alleged
     omission made in any Preliminary Prospectus, the Registration Statement or
     the Prospectus or any such amendment or supplement in reliance upon and in
     conformity with written information furnished to the Company by any
     Underwriter through Goldman, Sachs & Co. expressly for use therein.

          (b) Each of the Selling Stockholders will indemnify and hold harmless
     each Underwriter against any losses, claims, damages or liabilities, joint
     or several, to which such Underwriter may become subject, under the Act or
     otherwise, insofar as such losses, claims, damages or liabilities (or
     actions in respect thereof) arise out of or are based upon an untrue
     statement or alleged untrue statement of a material fact contained in any
     Preliminary Prospectus, the Registration Statement or the Prospectus, or
     any amendment or supplement thereto, or arise out of or are based upon the
     omission or alleged omission to state therein a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading, in each case to the extent, but only to the extent, that such
     untrue statement or alleged untrue statement or omission or alleged
     omission was made in any Preliminary Prospectus, the Registration Statement
     or the Prospectus or any such amendment or supplement in reliance upon and
     in conformity with written information furnished to the Company by such
     Selling Stockholder expressly for use therein; and will reimburse each
     Underwriter for any legal or other expenses reasonably incurred by such
     Underwriter in connection with investigating or defending any such action
     or claim as such expenses are incurred; provided, however, that such
     Selling Stockholder shall not be liable in any such case to the extent that
     any such loss, claim, damage or liability arises out of or is based upon an
     untrue statement or alleged untrue statement or omission or alleged
     omission made in any Preliminary Prospectus, the Registration Statement or
     the Prospectus or any such amendment or supplement in reliance upon and in
     conformity with written information furnished to the Company by any
     Underwriter through Goldman, Sachs & Co. expressly for use therein.

          (c) Each Underwriter will indemnify and hold harmless the Company and
     each Selling Stockholder against any losses, claims, damages or liabilities
     to which the Company or such

                                      15

<PAGE>
 
     Selling Stockholder may become subject, under the Act or otherwise, insofar
     as such losses, claims, damages or liabilities (or actions in respect
     thereof) arise out of or are based upon an untrue statement or alleged
     untrue statement of a material fact contained in any Preliminary
     Prospectus, the Registration Statement or the Prospectus, or any amendment
     or supplement thereto, or arise out of or are based upon the omission or
     alleged omission to state therein a material fact required to be stated
     therein or necessary to make the statements therein not misleading, in each
     case to the extent, but only to the extent, that such untrue statement or
     alleged untrue statement or omission or alleged omission was made in any
     Preliminary Prospectus, the Registration Statement or the Prospectus or any
     such amendment or supplement in reliance upon and in conformity with
     written information furnished to the Company by such Underwriter through
     Goldman, Sachs & Co. expressly for use therein; and will reimburse the
     Company and each Selling Stockholder for any legal or other expenses
     reasonably incurred by the Company or such Selling Stockholder in
     connection with investigating or defending any such action or claim as such
     expenses are incurred.

          (d) Promptly after receipt by an indemnified party under subsection
     (a), (b) or (c) above of notice of the commencement of any action, such
     indemnified party shall, if a claim in respect thereof is to be made
     against the indemnifying party under such subsection, notify the
     indemnifying party in writing of the commencement thereof; but the omission
     so to notify the indemnifying party shall not relieve it from any liability
     which it may have to any indemnified party otherwise than under such
     subsection. In case any such action shall be brought against any
     indemnified party and it shall notify the indemnifying party of the
     commencement thereof, the indemnifying party shall be entitled to
     participate therein and, to the extent that it shall wish, jointly with any
     other indemnifying party similarly notified, to assume the defense thereof,
     with counsel satisfactory to such indemnified party (who shall not, except
     with the consent of the indemnified party, be counsel to the indemnifying
     party), and, after notice from the indemnifying party to such indemnified
     party of its election so to assume the defense thereof, the indemnifying
     party shall not be liable to such indemnified party under such subsection
     for any legal expenses of other counsel or any other expenses, in each case
     subsequently incurred by such indemnified party, in connection with the
     defense thereof other than reasonable costs of investigation. No
     indemnifying party shall, without the written consent of the indemnified
     party, effect the settlement or compromise of, or consent to the entry of
     any judgment with respect to, any pending or threatened action or claim in
     respect of which indemnification or contribution may be sought hereunder
     (whether or not the indemnified party is an actual or potential party to
     such action or claim) unless such settlement, compromise or judgment (i)
     includes an unconditional release of the indemnified party from all
     liability arising out of such action or claim and (ii) does not include a
     statement as to or an admission of fault, culpability or a failure to act,
     by or on behalf of any indemnified party.

          (e) If the indemnification provided for in this Section 8 is
     unavailable to or insufficient to hold harmless an indemnified party under
     subsection (a), (b) or (c) above in respect of any losses, claims, damages
     or liabilities (or actions in respect thereof) referred to therein, then
     each indemnifying party shall contribute to the amount paid or payable by
     such indemnified party as a result of such losses, claims, damages or
     liabilities (or actions in respect thereof) in such proportion as is
     appropriate to reflect the relative benefits received by the Company and
     the Selling Stockholders on the one hand and the Underwriters on the other
     from the offering of the Shares. If, however, the allocation provided by
     the immediately preceding sentence is not permitted by applicable law or if
     the indemnified party failed to give the notice required under subsection
     (d) above, then each indemnifying party shall contribute to such amount
     paid or payable by such indemnified party in such proportion as is
     appropriate to

                                      16

<PAGE>
 
     reflect not only such relative benefits but also the relative fault of the
     Company and the Selling Stockholders on the one hand and the Underwriters
     on the other in connection with the statements or omissions which resulted
     in such losses, claims, damages or liabilities (or actions in respect
     thereof), as well as any other relevant equitable considerations. The
     relative benefits received by the Company and the Selling Stockholders on
     the one hand and the Underwriters on the other shall be deemed to be in the
     same proportion as the total net proceeds from the offering of the Shares
     purchased under this Agreement (before deducting expenses) received by the
     Company and the Selling Stockholders bear to the total underwriting
     discounts and commissions received by the Underwriters with respect to the
     Shares purchased under this Agreement, in each case as set forth in the
     table on the cover page of the Prospectus. The relative fault 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 relates to information supplied by the
     Company or the Selling Stockholders on the one hand or the Underwriters on
     the other and the parties' relative intent, knowledge, access to
     information and opportunity to correct or prevent such statement or
     omission. The Company, each of the Selling Stockholders and the
     Underwriters agree that it would not be just and equitable if contributions
     pursuant to this subsection (e) 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 which does not take account of the
     equitable considerations referred to above in this subsection (e). The
     amount paid or payable by an indemnified party as a result of the losses,
     claims, damages or liabilities (or actions in respect thereof) referred to
     above in this subsection (e) shall be deemed to include 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 subsection (e), no Underwriter shall be required to
     contribute any amount in excess of the amount by which the total price at
     which the Shares underwritten by it and distributed to the public were
     offered to the public 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 in this
     subsection (e) to contribute are several in proportion to their respective
     underwriting obligations and not joint.

          (f) The obligations of the Company and the Selling Stockholders under
     this Section 8 shall be in addition to any liability which the Company and
     the respective Selling Stockholders may otherwise have and shall extend,
     upon the same terms and conditions, to each person, if any, who controls
     any Underwriter within the meaning of the Act; and the obligations of the
     Underwriters under this Section 8 shall be in addition to any liability
     which the respective Underwriters may otherwise have and shall extend, upon
     the same terms and conditions, to each officer and director of the Company
     and to each person, if any, who controls the Company or any Selling
     Stockholder within the meaning of the Act.

9.        (a)  If any Underwriter shall default in its obligation to purchase
     the Shares which it has agreed to purchase hereunder at a Time of Delivery,
     you may in your discretion arrange for you or another party or other
     parties to purchase such Shares on the terms contained herein. If within
     thirty-six hours after such default by any Underwriter you do not arrange
     for the purchase of such Shares, then the Company and the Selling
     Stockholders shall be entitled to a further period of thirty-six hours
     within which to procure another party or other parties satisfactory to you
     to purchase such Shares on such terms. In the event that, within the
     respective prescribed periods, you notify the Company and the Selling
     Stockholders that you have so arranged for the purchase of such Shares, or
     the Company and the Selling

                                      17

<PAGE>
 
     Stockholders notify you that they have so arranged for the purchase of such
     Shares, you or the Company and the Selling Stockholders shall have the
     right to postpone such Time of Delivery for a period of not more than seven
     days, in order to effect whatever changes may thereby be made necessary in
     the Registration Statement or the Prospectus, or in any other documents or
     arrangements, and the Company agrees to file promptly any amendments to the
     Registration Statement or the Prospectus which in your opinion may thereby
     be made necessary. The term "Underwriter" as used in this Agreement shall
     include any person substituted under this Section with like effect as if
     such person had originally been a party to this Agreement with respect to
     such Shares.

          (b)  If, after giving effect to any arrangements for the purchase of
     the Shares of a defaulting Underwriter or Underwriters by you and the
     Company and the Selling Stockholders as provided in subsection (a) above,
     the aggregate number of such Shares which remains unpurchased does not
     exceed one-eleventh of the aggregate number of all the Shares to be
     purchased at such Time of Delivery, then the Company and the Selling
     Stockholders shall have the right to require each non-defaulting
     Underwriter to purchase the number of Shares which such Underwriter agreed
     to purchase hereunder at such Time of Delivery and, in addition, to require
     each non-defaulting Underwriter to purchase its pro rata share (based on
     the number of Shares which such Underwriter agreed to purchase hereunder)
     of the Shares of such defaulting Underwriter or Underwriters for which such
     arrangements have not been made; but nothing herein shall relieve a
     defaulting Underwriter from liability for its default.

          (c)  If, after giving effect to any arrangements for the purchase of
     the Shares of a defaulting Underwriter or Underwriters by you and the
     Company and the Selling Stockholders as provided in subsection (a) above,
     the aggregate number of such Shares which remains unpurchased exceeds one-
     eleventh of the aggregate number of all the Shares to be purchased at such
     Time of Delivery, or if the Company and the Selling Stockholders shall not
     exercise the right described in subsection (b) above to require non-
     defaulting Underwriters to purchase Shares of a defaulting Underwriter or
     Underwriters, then this Agreement (or, with respect to the Second Time of
     Delivery, the obligations of the Underwriters to purchase and of the
     Company to sell the Optional Shares) shall thereupon terminate, without
     liability on the part of any non-defaulting Underwriter, the Company or the
     Selling Stockholders, except for the expenses to be borne by the Company
     and the Selling Stockholders and the Underwriters as provided in Section 6
     hereof and the indemnity and contribution agreements in Section 8 hereof;
     but nothing herein shall relieve a defaulting Underwriter from liability
     for its default.

     10.  The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Selling Stockholders and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, the Company, or any of the Selling Stockholders or any officer or
director or controlling person of the Company or any controlling person of any
Selling Stockholders, and shall survive delivery of and payment for the Shares.

     11.  If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor the Selling Stockholders shall then be under any
liability to any Underwriter except as provided in Sections 6 and 8 hereof; but,
if for any other reason, any Shares are not delivered by or on behalf of the
Company (with respect to the Optional Shares) and the Selling Stockholders (with
respect to the Firm Shares) as provided herein, the Company and each of the
Selling Stockholders pro rata (based on the number of Shares to be sold by the
Company and such Selling Stockholder hereunder) will reimburse the Underwriters
through you for all out-of-pocket expenses approved in writing by you, including
fees and disbursements of counsel, reasonably incurred by the Underwriters


                                       18

<PAGE>
 
in making preparations for the purchase, sale and delivery of the Shares not so
delivered, but the Company and the Selling Stockholders shall then be under no
further liability to any Underwriter in respect of the Shares not so delivered
except as provided in Sections 6 and 8 hereof.

     12.  In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by Goldman, Sachs & Co. on behalf of you as the
representatives.

     All statements, requests, notices and agreements hereunder required to be
in writing, if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to you as the representatives in care of Goldman, Sachs &
Co., 85 Broad Street, New York, New York 10004, Attention: Registration
Department; if to any Selling Stockholder shall be delivered or sent by mail,
telex or facsimile transmission to counsel for such Selling Stockholder at its
address set forth in Schedule II hereto; and if to the Company shall be
delivered or sent by mail, telex or facsimile transmission to the address of the
Company set forth in the Registration Statement, Attention: Secretary; provided,
however, that any notice to an Underwriter pursuant to Section 8(d) hereof shall
be delivered or sent by mail, telex or facsimile transmission to such
Underwriter at its address set forth in its Underwriters' Questionnaire, or
telex constituting such Questionnaire, which address will be supplied to the
Company or the Selling Stockholders by you upon request. Any such statements,
requests, notices or agreements shall take effect at the time of receipt
thereof.

     13.  This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company and the Selling Stockholders and, to the
extent provided in Sections 8 and 10 hereof, the officers and directors of the
Company and the Selling Stockholders and each person who controls the Company,
any Selling Stockholder or any Underwriter, and their respective heirs,
executors, administrators, successors and assigns, and no other person shall
acquire or have any right under or by virtue of this Agreement. No purchaser of
any of the Shares from any Underwriter shall be deemed a successor or assign by
reason merely of such purchase.

     14.  Time shall be of the essence of this Agreement. As used herein, the
term "business day" shall mean any day when the Commission's office in
Washington, D.C. is open for business.

     15.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK.

     16.  This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

     If the foregoing is in accordance with your understanding, please sign and
return to us one for the Company, each Selling Stockholder and for each of the
Representatives plus one for each counsel counterparts hereof, and upon the
acceptance hereof by you, on behalf of each of the Underwriters, this letter and
such acceptance hereof shall constitute a binding agreement between each of the
Underwriters, the Company and each of the Selling Stockholders. It is understood
that your acceptance of this letter on behalf of each of the Underwriters is
pursuant to the authority set forth in a form of Agreement among Underwriters
(U.S. Version), the form of which shall be submitted to the Company and the
Selling Stockholders for examination upon request, but without warranty on your
part as to the authority of the signers thereof.

     Pursuant to Section 7(b) of the Underwriting Agreement, Sidley & Austin
shall furnish an opinion to the Underwriters to the effect that:

          (i) The Company has been duly incorporated and is validly existing as
     a corporation in good standing under the laws of the State of Delaware,
     with corporate power and corporate authority to own its properties and
     conduct its business as described in the Prospectus;

          (ii)  The Company has an authorized capitalization as set forth in the
     Prospectus, and all of the issued shares of capital stock of the Company
     issued and outstanding as of the date hereof (including the Firm Shares)
     have been duly and validly authorized and issued and are fully paid and
     nonassessable; the Optional Shares, when certificates therefor have been
     duly executed, countersigned and registered and delivered to and paid for
     by the Underwriters in accordance with the terms of the Underwriting
     Agreement, will constitute shares of Stock which have been duly authorized
     and validly issued and are fully paid and nonassessable; and the Shares
     conform in all material respects to the description of the Stock contained
     in the Prospectus;

          (iii)  This Agreement and the International Underwriting Agreement
     have been duly authorized, executed and delivered by the Company and the
     Selling Stockholders;

          (iv)  The statements set forth in the Prospectus under the caption
     "Description of Capital Stock", insofar as they purport to constitute a
     summary of the terms of the Stock, under the caption "Certain United States
     Tax Consequences to Non-U.S. Holders", insofar as they purport to describe
     the provisions of laws referred to therein, and under the caption
     "Underwriting", insofar as they purport to describe the provisions of the
     laws and documents referred to therein, are accurate and complete in all
     material respects; and

          (v)  The Registration Statement and the Prospectus and any further
     amendments and supplements thereto made by the Company prior to such Time
     of Delivery (other than the financial statements and related schedules
     therein, as to which such counsel need express no belief) comply as to form
     in all material respects with the requirements of the Act and the rules and
     regulations thereunder; nothing has come to their attention that causes
     them to believe that, as of its effective date, the Registration Statement
     or any further amendment thereto made by the Company prior to such Time of
     Delivery (other than the financial statements and related statements and
     related schedules therein, as to which such counsel need express no belief)
     contained an 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, as of its date or as of the Time
     of Delivery, the Prospectus or any further amendment or supplement thereto
     made by the Company prior to such Time of Delivery (other than the
     financial statements and related schedules therein, as to which such
     counsel need express no belief) contained an untrue statement of a material
     fact or omitted to state a material fact necessary to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading.

     In rendering such opinion, such counsel may state that they express no
opinion as to the laws of any jurisdiction other than the laws of the United
States of America and the laws of the State of Illinois and the General
Corporation Law of the State of Delaware.

     Pursuant to Section 7(c) of the Underwriting Agreement, Edward A.
Christensen, the Vice President, Secretary and General Counsel of the Company,
shall furnish an opinion to the Underwriters to the effect that:

          (i) The Company has been duly qualified as a foreign corporation for
     the transaction of business and is in good standing under the laws of each
     other jurisdiction in which it owns or leases properties or conducts any
     business so as to require such qualification, or is subject to no material
     liability or disability by reason of failure to be so qualified in any such
     jurisdiction;

          (ii)  Each "Significant Subsidiary," as defined in Rule 405 of the
     rules and regulations promulgated under the Act, of the Company has been
     duly incorporated and is validly existing as a corporation in good standing
     under the laws of its jurisdiction of incorporation; and all of the issued
     shares of capital stock of each such subsidiary have been duly and validly
     authorized and issued, are fully paid and non-assessable, and (except for
     directors' qualifying shares) are owned of record directly or indirectly by
     the Company, free and clear of all liens or encumbrances, except for liens
     arising under the Company's credit agreement or any other document filed as
     an exhibit to or incorporated by reference in the Registration Statement;

          (iii)  To the best of such counsel's knowledge and other than as set
     forth in the Prospectus, there are no legal or governmental proceedings
     pending to which the Company or any of its subsidiaries is a party or of
     which any property of the Company or any of its subsidiaries is the subject
     which, if determined adversely to the Company or any of its subsidiaries,
     would individually or in the aggregate have a material adverse effect on
     the current or future consolidated financial position, stockholders' equity
     or results of operations of the Company and its subsidiaries; and, to the
     best of such counsel's knowledge, no such proceedings are threatened or
     contemplated by governmental authorities or threatened by others;

          (iv)  The issue and sale of the Shares to be issued by the Company
     being delivered at such Time of Delivery by the Company and the compliance
     by the Company with all of the provisions of this Agreement and the
     International Underwriting Agreement and the consummation of the
     transactions herein and therein contemplated will not conflict with or
     result in a breach or violation of any of the terms or provisions of, or
     constitute a default under, any indenture, mortgage, deed of trust, loan
     agreement or other agreement or instrument known to such counsel to which
     the Company or any of its subsidiaries is a party or by which the Company
     or any of its subsidiaries is bound or to which any of the property or
     assets of the Company or any of its subsidiaries is subject, nor will such
     action result in any violation of the provisions of the Certificate of
     Incorporation or By-laws of the Company or any statute or any order, rule
     or regulation known to such counsel of any court or governmental agency or
     body having jurisdiction over the Company or any of its subsidiaries or any
     of their properties;

          (v)  Neither the Company, any of its Significant Subsidiaries nor, to
     the best of such counsel's knowledge, any of the Company's other
     subsidiaries is in violation of its Certificate of Incorporation or By-laws
     and, to the best of such counsel's knowledge, neither the Company nor any
     of its subsidiaries is in default in the performance or observance of any
     material obligation, agreement, covenant or condition contained in any
     indenture, mortgage, deed of trust, loan agreement, lease or other
     agreement or instrument to which it is a party or by which it or any of its
     properties may be bound;

          (vi)  No consent, approval, authorization, order, registration or
     qualification of or with any court or governmental agency or body is
     required for the issue and sale of the Shares to be issued by the Company
     being delivered at such Time of Delivery or the consummation by the Company
     of the transactions contemplated by this Agreement and the International
     Underwriting Agreement and the Company is not required to obtain any
     consent, approval, authorization, order, registration or qualification of
     or with any court or governmental agency or body in connection with the
     sale of the Firm Shares, in each case except the registration under the Act
     of the Shares, and such consents, approvals, authorizations, registrations
     or qualifications as may be required under state or foreign securities or
     Blue Sky laws in connection with the purchase and distribution of the
     Shares by the Underwriters and the International Underwriters; and

          (vii)  The documents incorporated by reference in the Prospectus or
     any further amendment or supplement thereto made by the Company prior to
     such Time of Delivery (other than the financial

                                       1
<PAGE>
 
     statements and related schedules therein, as to which such counsel need
     express no opinion), when they became effective or were filed with the
     Commission, as the case may be, complied as to form in all material
     respects with the requirements of the Act or the Exchange Act, as
     applicable, and the rules and regulations of the Commission thereunder; and
     I have no reason to believe that any of such documents, when such documents
     became effective or were so filed, as the case may be, contained, in the
     case of a registration statement which became effective under the Act, an
     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, in the case of other documents which were filed under
     the Exchange Act with the Commission, an untrue statement of a material
     fact or omitted to state a material fact necessary in order to make the
     statements therein, in the light of the circumstances under which they were
     made when such documents were so filed, not misleading.

     In rendering such opinion, such counsel may (i) state that he expresses no
opinion as to the laws of any jurisdiction other than the laws of the United
States of America, to the extent referred to therein, and the laws of the States
of New York and Florida and the General Corporation Law of the State of Delaware
and (ii) rely upon opinions of local counsel and in respect of matters of fact
upon certificates of officers of the Company, provided that such counsel shall
state that he believes that both you and he are justified in relying upon such
opinions and certificates.

     Pursuant to Section 7(c) of the Underwriting Agreement, Skadden, Arps,
Slate, Meagher & Flom, counsel for the Company, shall furnish an opinion to the
Underwriters to the effect that:

          (i)  The Company has been duly incorporated and is validly existing as
     a corporation in good standing under the laws of the State of Delaware,
     with power and corporate authority to own its properties and conduct its
     business as described in the Prospectus;

          (ii)  The Company has an authorized capitalization as set forth in the
     Prospectus, and all of the issued shares of capital stock of the Company
     issued and outstanding immediately prior to the date hereof have been duly
     and validly authorized and issued and are fully paid and nonassessable; the
     Firm Shares have been duly and validly authorized and issued and are fully
     paid and nonassessable; the Optional Shares have been duly and validly
     authorized for issuance and when delivered and paid for in full in
     accordance with the Underwriting Agreement, will be duly and validly issued
     and fully paid and nonassessable; and the Shares conform in all material
     respects as to legal matters to the description of the Stock contained in
     the Prospectus;

          (iii)  This Agreement and the International Underwriting Agreement
     have been duly authorized, executed and delivered by the Company and the
     Selling Stockholders; and

          (iv)  The Registration Statement as of its effective date and the
     Prospectus as of its date and any further amendments and supplements
     thereto made by the Company prior to such Time of Delivery (other than the
     financial statements and related schedules therein, as to which such
     counsel need express no opinion) appeared on their face to be appropriately
     responsive in all material respects to, and complied as to form in all
     material respects with the requirements of the Act and the rules and
     regulations thereunder, although they do not assume any responsibility for
     the accuracy, completeness or fairness of the statements contained in the
     Registration Statement or the Prospectus, except to the extent set forth in
     subsection (v) of this Annex III; they have no reason to believe that, as
     of its effective date, the Registration Statement (taken together with the
     documents incorporated by reference therein) or any further amendment
     thereto made by the Company prior to such Time of Delivery (other than the
     financial statements and related statements and related schedules therein,
     as to which such counsel need express no opinion) contained an 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, as of its date, the Prospectus (taken together with the
     documents incorporated by reference therein) or any further amendment or
     supplement thereto made by the Company prior to such Time of Delivery
     (other than the financial statements and related schedules therein, as to
     which such counsel need express no opinion) contained an untrue statement
     of a material fact or omitted to state a material fact necessary to make
     the statements therein, in the light of the circumstances under which they
     were made, not misleading or that, as of such Time of Delivery, either the
     Registration Statement or the Prospectus (taken together with the documents
     incorporated by reference therein) or any further amendment or supplement
     thereto made by the Company prior to such Time of Delivery (other than the
     financial statements and related schedules therein, as to which such
     counsel need express no opinion) contains an untrue statement of a material
     fact or omits to state a material fact necessary to make the statements
     therein, in the light of the circumstances under which they were made, not
     misleading; and they do not know of any amendment to the Registration
     Statement required to be filed any contracts or other documents required to
     be filed as an exhibit to the Registration Statement.

          (v)  The statements set forth in the Prospectus under the caption
     "Description of Capital Stock", insofar as they purport to constitute a
     summary of the terms of the Stock, under the caption "Certain United States
     Tax Consequences to Non-U.S. Holders", insofar as they purport to describe
     the provisions of laws referred to therein, and to select paragraphs under
     the caption "Underwriting", insofar as they purport to describe the
     provisions of the documents referred to therein, are accurate and complete
     in all material respects; and

          (vi)  The Company is not regulated or required to be registered as an
     "investment company" under the Investment Company Act.

                                       1

     In rendering such opinion, such counsel may (i) state that they express no
opinion as to the laws of any jurisdiction other than the laws of the United
States of America, to the extent referred to therein, and the laws of the State
of Delaware and (ii) rely upon the opinions of local counsel and in respect of
matters of fact upon certificates of officers of the Company.

     Pursuant to Section 7(d) of the Underwriting Agreement, the accountants
shall furnish letters to the Underwriters to the effect that:

          (i) They are independent certified public accountants with respect to
     the Company and its subsidiaries within the meaning of the Act and the
     applicable published rules and regulations thereunder;

          (ii) In their opinion, the financial statements and any supplementary
     financial information and schedules (and, if applicable, financial
     forecasts and/or pro forma financial information) examined by them and
     included in the Prospectus or the Registration Statement comply as to form
     in all material respects with the applicable accounting requirements of the
     Act and the related published rules and regulations thereunder; and, if
     applicable, they have made a review in accordance with standards
     established by the American Institute of Certified Public Accountants of
     the unaudited consolidated interim financial statements, selected financial
     data, pro forma financial information, financial forecasts and/or condensed
     financial statements derived from audited financial statements of the
     Company for the periods specified in such letter, as indicated in their
     reports thereon, copies of which have been furnished separately to the
     representatives of the Underwriters (the "Representatives");

          (iii) They have made a review in accordance with standards established
     by the American Institute of Certified Public Accountants of the unaudited
     condensed consolidated statements of income, consolidated balance sheets
     and consolidated statements of cash flows included in the Prospectus as
     indicated in their reports thereon copies of which have been separately
     furnished to the Representatives and on the basis of specified procedures
     including inquiries of officials of the Company who have responsibility for
     financial and accounting matters regarding whether the unaudited condensed
     consolidated financial statements referred to in paragraph (v)(A)(i) below
     comply as to form in all material respects with the applicable accounting
     requirements of the Act and the related published rules and regulations,
     nothing came to their attention that caused them to believe that the
     unaudited condensed consolidated financial statements do not comply as to
     form in all material respects with the applicable accounting requirements
     of the Act and the related published rules and regulations;

          (iv) They have compared the information in the Prospectus under
     selected captions with the disclosure requirements of Regulation S-K and on
     the basis of limited procedures specified in such letter nothing came to
     their attention as a result of the foregoing procedures that caused them to
     believe that this information does not conform in all material respects
     with the disclosure requirements of Items 301, 302, 402 and 503(d),
     respectively, of Regulation S-K;

          (v) On the basis of limited procedures, not constituting an
     examination in accordance with generally accepted auditing standards,
     consisting of a reading of the unaudited financial statements and other
     information referred to below, a reading of the latest available interim
     financial statements of the Company and its subsidiaries, inspection of the
     minute books of the Company and its subsidiaries since the date of the
     latest audited financial statements included in the Prospectus, inquiries
     of officials of the Company and its subsidiaries responsible for financial
     and accounting matters and such other inquiries and procedures as may be
     specified in such letter, nothing came to their attention that caused them
     to believe that:

               (A) (i) the unaudited consolidated statements of income,
          consolidated balance sheets and consolidated statements of cash flows
          included in the Prospectus do not comply as to form in all material
          respects with the applicable accounting requirements of the Act and
          the related published rules and regulations, or (ii) any material
          modifications should be made to the unaudited condensed consolidated
          statements of income, consolidated balance sheets and consolidated
          statements of cash flows included in the Prospectus for them to be in
          conformity with generally accepted accounting principles;

               (B) any other unaudited income statement data and balance sheet
          items included in the Prospectus do not agree with the corresponding
          items in the unaudited consolidated financial statements from which
          such data and items were derived, and any such unaudited

                                       1

          data and items were not determined on a basis substantially consistent
          with the basis for the corresponding amounts in the audited
          consolidated financial statements included in the Prospectus;

               (C) the unaudited financial statements which were not included in
          the Prospectus but from which were derived any unaudited condensed
          financial statements referred to in Clause (A) and any unaudited
          income statement data and balance sheet items included in the
          Prospectus and referred to in Clause (B) were not determined on a
          basis substantially consistent with the basis for the audited
          consolidated financial statements included in the Prospectus;

               (D) any unaudited pro forma consolidated condensed financial
          statements included in the Prospectus do not comply as to form in all
          material respects with the applicable accounting requirements of the
          Act and the published rules and regulations thereunder or the pro
          forma adjustments have not been properly applied to the historical
          amounts in the compilation of those statements;

               (E) as of a specified date not more than five days prior to the
          date of such letter, there have been any changes in the consolidated
          capital stock (other than issuances of capital stock upon exercise of
          options and stock appreciation rights, upon earn-outs of performance
          shares and upon conversions of convertible securities, in each case
          which were outstanding on the date of the latest financial statements
          included in the Prospectus) or any increase in the consolidated long-
          term debt of the Company and its subsidiaries, or any decreases in
          consolidated net current assets or stockholders' equity or other items
          specified by the Representatives, or any increases in any items
          specified by the Representatives, in each case as compared with
          amounts shown in the latest balance sheet included in the Prospectus,
          except in each case for changes, increases or decreases which the
          Prospectus discloses have occurred or may occur or which are described
          in such letter; and

               (F) for the period from the date of the latest financial
          statements included in the Prospectus to the specified date referred
          to in Clause (E) there were any decreases in consolidated net revenues
          or operating profit or the total or per share amounts of consolidated
          net income or other items specified by the Representatives, or any
          increases in any items specified by the Representatives, in each case
          as compared with the comparable period of the preceding year and with
          any other period of corresponding length specified by the
          Representatives, except in each case for decreases or increases which
          the Prospectus discloses have occurred or may occur or which are
          described in such letter; and

          (vi) In addition to the examination referred to in their report(s)
     included in the Prospectus and the limited procedures, inspection of minute
     books, inquiries and other procedures referred to in paragraphs (iii) and
     (v) above, they have carried out certain specified procedures, not
     constituting an examination in accordance with generally accepted auditing
     standards, with respect to certain amounts, percentages and financial
     information specified by the Representatives, which are derived from the
     general accounting records of the Company and its subsidiaries, which
     appear in the Prospectus, or in Part II of, or in exhibits and schedules
     to, the Registration Statement specified by the Representatives, and have
     compared certain of such amounts, percentages and financial information
     with the accounting records of the Company and its subsidiaries and have
     found them to be in agreement.

                                                                October __, 1996

Jefferies International Limited
 As representatives of the several Underwriters
  named in Schedule I hereto,
c/o Goldman Sachs International
Peterborough Court,
133 Fleet Street,
London EC4A 2BB, England.

Ladies and Gentlemen:

     Certain stockholders named in Schedule II hereto (the "Selling
Stockholders") of Culligan Water Technologies, Inc., a Delaware corporation (the
"Company"), propose, subject to the terms and conditions stated herein, to sell
to the Underwriters named in Schedule I hereto (the "Underwriters") an aggregate
of 998,984 shares (the "Firm Shares") and, at the election of the Underwriters,
the Company proposes to issue and sell up to 149,848 additional shares (the
"Optional Shares") of Common Stock, par value $.01 per share (the "Stock") of
the Company (the Firm Shares and the Optional Shares which the Underwriters
elect to purchase pursuant to Section 2 hereof being collectively called the
"Shares").

     It is understood and agreed to by all parties that the Company and the
Selling Stockholders are concurrently entering into an agreement, a copy of
which is attached hereto (the "U.S. Underwriting Agreement"), providing for the
offering by the Company and the Selling Stockholders of up to a total of
4,595,328 shares of Stock (the "U.S. Shares") including the overallotment option
thereunder, through arrangements with certain underwriters in the United States
(the "U.S. Underwriters"), for whom Goldman, Sachs & Co., Bear, Stearns & Co.
Inc., NatWest Securities Limited, Smith Barney Inc. and Jefferies & Company,
Inc. are acting as representatives. Anything herein and therein to the contrary
notwithstanding, the respective closings under this Agreement and the U.S.
Underwriting Agreement are hereby expressly made conditional on one another. The
Underwriters hereunder and the U.S. Underwriters are simultaneously entering
into an Agreement between U.S. and International Underwriting Syndicates (the
"Agreement between Syndicates") which provides, among other things, for the
transfer of shares of Stock between the two syndicates and for consultation by
you with Goldman, Sachs & Co. prior to exercising the rights of the Underwriters
under Section 7 hereof. Two forms of prospectus are to be used in connection
with the offering and sale of shares of Stock contemplated by the foregoing, one
relating to the Shares hereunder and the other relating to the U.S. Shares. The
latter form of prospectus will be identical to the former except for certain
substitute pages as included in the registration statement and amendments
thereto as mentioned below.
<PAGE>
 
Except as used in Sections 2, 3, 4, 9 and 11 herein, and except as the context
may otherwise require, references hereinafter to the Shares shall include all of
the shares of Stock which may be sold pursuant to either this Agreement or the
U.S. Underwriting Agreement, and references herein to any prospectus whether in
preliminary or final form, and whether as amended or supplemented, shall include
both of the U.S. and the international versions thereof.

     In addition, this Agreement incorporates by reference certain provisions
from the U.S. Underwriting Agreement (including the related definitions of
terms, which are also used elsewhere herein) and, for purposes of applying the
same, references (whether in these precise words or their equivalent) in the
incorporated provisions to the "Underwriters" shall be to the Underwriters
hereunder, to the "Shares" shall be to the Shares hereunder as just defined, to
"this Agreement" (meaning therein the U.S. Underwriting Agreement) shall be to
this Agreement (except where this Agreement is already referred to or as the
context may otherwise require) and to the representatives of the Underwriters or
to Goldman, Sachs & Co. shall be to the addressees of this Agreement and to
Goldman Sachs International ("GSI"), and, in general, all such provisions and
defined terms shall be applied mutatis mutandis as if the incorporated
provisions were set forth in full herein having regard to their context in this
Agreement as opposed to the U.S. Underwriting Agreement.

  1.  The Company and each of the Selling Stockholders hereby make with the
Underwriters the same representations, warranties and agreements as are set
forth in Section 1 of the U.S. Underwriting Agreement, which Section is
incorporated herein by this reference.

  2.  Subject to the terms and conditions herein set forth, (a) each of the
Selling Stockholders agrees, severally and not jointly, to sell to each of the
Underwriters, and each of the Underwriters agrees, severally and not jointly, to
purchase from each of the Selling Stockholders, at a purchase price per share of
$_____, the number of Firm Shares (to be adjusted by you so as to eliminate
fractional shares) determined by multiplying the aggregate number of Firm Shares
to be sold by each of the Selling Stockholders as set forth opposite their
respective names in Schedule II hereto by a fraction, the numerator of which is
the aggregate number of Firm Shares to be purchased by such Underwriter as set
forth opposite the name of such Underwriter in Schedule I hereto and the
denominator of which is the aggregate number of Firm Shares to be purchased by
all the Underwriters from all the Selling Stockholders hereunder and (b) in the
event and to the extent that the Underwriters shall exercise the election to
purchase Optional Shares as provided below, the Company agrees to issue and sell
to each of the Underwriters, and each of the Underwriters agrees, severally and
not jointly, to purchase from the Company, at the purchase price per share set
forth in clause (a) of this Section 2, that portion of the number of Optional
Shares as to which such election shall have been exercised (to be adjusted by
you so as to eliminate fractional shares) determined by multiplying such number
of Optional Shares by a fraction the numerator of which is the maximum number of
Optional Shares which such Underwriter is entitled to purchase as set forth
opposite the name of such Underwriter in Schedule I hereto and the denominator
of which is the maximum number of Optional Shares that all of the Underwriters
are entitled to purchase hereunder.

     The Company hereby grants to the Underwriters the right to purchase at
their election up to 149,848 Optional Shares, at the purchase price per share
set forth in the paragraph above, for the sole purpose of covering
overallotments in the sale of the Firm Shares. Any such election to purchase
Optional Shares may be exercised only by written notice from you to the Company,
given within a period of 30 calendar days after the date of this Agreement,
setting forth the aggregate number of Optional Shares to be purchased and the
date on which such Optional Shares are to be delivered, as determined by you but
in no event earlier than the First Time of Delivery (as defined in Section 4
hereof) or, unless you and the Company otherwise agree in writing, earlier than
two or later than ten business days after the date of such notice.

                                       2

    3.  Upon the authorization by GSI of the release of the Firm Shares, the
several Underwriters propose to offer the Firm Shares for sale upon the terms
and conditions set forth in the Prospectus and in the forms of Agreement among
Underwriters (International Version) and Selling Agreements, which have been
previously submitted to the Company by you. Each Underwriter hereby makes to and
with the Company and the Selling Stockholders the representations and agreements
of such Underwriter as a member of the selling group contained in Sections 3(d)
and 3(e) of the form of Selling Agreements.

    4.  (a) The Shares to be purchased by each Underwriter hereunder, in
definitive form, and in such authorized denominations and registered in such
names as GSI may request upon at least forty-eight hours' prior notice to the
Company and the Selling Stockholders shall be delivered by or on behalf of the
Company, in the case of the Optional Shares, and the Selling Stockholders, in
the case of the Firm Shares, to GSI, through the facilities of the Depository
Trust Company ("DTC"), for the account of such Underwriter, against payment by
or on behalf of such Underwriter of the purchase price therefor by wire
transfer, payable to the order of the Company and each of the Selling
Stockholders, as their interests may appear, in federal (same day) funds. The
Selling Stockholders will cause the certificates representing the Firm Shares,
and the Company will cause the certificates representing the Optional Shares, to
be made available for checking and packaging at least twenty-four hours prior to
the Time of Delivery (as defined below) with respect thereto at the office of
DTC or its designated custodian (the "Designated Office"). The time and date of
such delivery and payment shall be, with respect to the Firm Shares, 9:30 a.m.,
New York City time, on October __, 1996 or such other time and date as GSI and
the Company and the Selling Stockholders may agree upon in writing, and, with
respect to the Optional Shares, 9:30 a.m., New York City time, on the date
specified by GSI in the written notice given by GSI of the Underwriters'
election to purchase such Optional Shares, or such other time and date as GSI
and the Company may agree upon in writing. Such time and date for delivery of
the Firm Shares is herein called the "First Time of Delivery", such time and
date for delivery of the Optional Shares, if not the First Time of Delivery, is
herein called the "Second Time of Delivery", and each such time and date for
delivery is herein called a "Time of Delivery".

    (b) The documents to be delivered at each Time of Delivery by or on behalf
of the parties hereto pursuant to Section 7(k) of the U.S. Underwriting
Agreement, including the cross receipt for the Shares and any additional
documents requested by the Underwriters pursuant to Section 7(k) of the U.S.
Underwriting Agreement hereof, will be delivered at the offices of Sidley &
Austin, 875 Third Avenue, New York, New York 10022 (the "Closing Location"), and
the Shares will be delivered at the Designated Office, all at such Time of
Delivery. A meeting will be held at the Closing Location at 3:00 p.m., New York
City time, on the New York Business Day next preceding such Time of Delivery, at
which meeting the final drafts of the documents to be delivered pursuant to the
preceding sentence will be available for review by the parties hereto. For the
purposes of this Section 4, "New York Business Day" shall mean each Monday,
Tuesday, Wednesday, Thursday and Friday which is not a day on which banking
institutions in New York are generally authorized or obligated by law or
executive order to close.

    5.  The Company hereby makes to the Underwriters the same agreements as are
set forth in Section 5 of the U.S. Underwriting Agreement, which Section is
incorporated herein by this reference.

    6.  The Company, each of the Selling Stockholders and the Underwriters
hereby agree with respect to certain expenses on the same terms as are set forth
in Section 6 of the U.S. Underwriting Agreement, which Section is incorporated
herein by this reference.

    7.  Subject to the provisions of the Agreement between Syndicates, the
obligations of the Underwriters hereunder shall be subject, in their discretion,
at each Time of Delivery, to the condition

                                       3
<PAGE>
 
that all representations and warranties and other statements of the Company and
the Selling Stockholders herein are, at and as of such Time of Delivery, true
and correct, the condition that the Company and the Selling Stockholders shall
have performed all of their obligations hereunder theretofore to be performed,
and additional conditions identical to those set forth in Section 7 of the U.S.
Underwriting Agreement, which Section is incorporated herein by this reference.

     8.   (a)  The Company will indemnify and hold harmless each Underwriter
against any losses, claims, damages or liabilities, joint or several, to which
such Underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon an untrue statement or alleged untrue statement of a
material fact contained in any Preliminary Prospectus, the Registration
Statement or the Prospectus, or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse each Underwriter for any legal or
other expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such action or claim as such expenses are
incurred; provided, however, that the Company shall not be liable in any such
case to the extent that any such loss, claim, damage or liability arises out of
or is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in any Preliminary Prospectus, the Registration Statement
or the Prospectus or any such amendment or supplement in reliance upon and in
conformity with written information furnished to the Company by any Underwriter
through GSI expressly for use therein.

     (b) Each of the Selling Stockholders will indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in any Preliminary Prospectus, the Registration
Statement or the Prospectus or any such amendment or supplement in reliance upon
and in conformity with written information furnished to the Company by such
Selling Stockholder expressly for use therein; and will reimburse each
Underwriter for any legal or other expenses reasonably incurred by such
Underwriter in connection with investigating or defending any such action or
claim as such expenses are incurred; provided, however, that such Selling
Stockholder shall not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
any Preliminary Prospectus, the Registration Statement or the Prospectus or any
such amendment or supplement in reliance upon and in conformity with written
information furnished to the Company by any Underwriter through Goldman, Sachs &
Co. expressly for use therein.

     (c) Each Underwriter will indemnify and hold harmless the Company and each
Selling Stockholder against any losses, claims, damages or liabilities to which
the Company and each Selling Stockholder may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon an untrue statement or alleged
untrue statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or the Prospectus, or any amendment or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission

                                       4
<PAGE>
 
or alleged omission was made in any Preliminary Prospectus, the Registration
Statement or Prospectus or any such amendment or supplement in reliance upon and
in conformity with written information furnished to the Company by such
Underwriter through GSI expressly for use therein; and will reimburse the
Company and each Selling Stockholder for any legal or other expenses reasonably
incurred by the Company and each Selling Stockholder in connection with
investigating or defending any such action or claim as such expenses are
incurred.

    (d) Promptly after receipt by an indemnified party under subsection (a), (b)
or (c) above of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against the indemnifying
party under such subsection, notify the indemnifying party in writing of the
commencement thereof; but the omission so to notify the indemnifying party shall
not relieve it from any liability which it may have to any indemnified party
otherwise than under such subsection.  In case any such action shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party (who shall not, except with the
consent of the indemnified party, be counsel to the indemnifying party), and,
after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party shall not be
liable to such indemnified party under such subsection for any legal expenses of
other counsel or any other expenses, in each case subsequently incurred by such
indemnified party, in connection with the defense thereof other than reasonable
costs of investigation.  No indemnifying party shall, without the written
consent of the indemnified party, effect the settlement or compromise of, or
consent to the entry of any judgment with respect to, any pending or threatened
action or claim in respect of which indemnification or contribution may be
sought hereunder (whether or not the indemnified party is an actual or potential
party to such action or claim) unless such settlement, compromise or judgment
(i) includes an unconditional release of the indemnified party from all
liability arising out of such action or claim and (ii) does not include a
statement as to or an admission of fault, culpability or a failure to act, by or
on behalf of any indemnified party.

    (e) If the indemnification provided for in this Section 8 is unavailable to
or insufficient to hold harmless an indemnified party under subsection (a), (b)
or (c) above in respect of any losses, claims, damages or liabilities (or
actions in respect thereof) referred to therein, then each indemnifying party
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect the relative benefits
received by the Company and the Selling Stockholders on the one hand and the
Underwriters on the other from the offering of the Shares. If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law or if the indemnified party failed to give the notice required
under subsection (d) above, then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company and the Selling Stockholders on the one hand and the
Underwriters on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable considerations.  The relative
benefits received by the Company and the Selling Stockholders on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total net proceeds from the offering of the Shares purchased under this
Agreement (before deducting expenses) received by the Company and the Selling
Stockholders bear to the total underwriting discounts and commissions received
by the Underwriters with respect to the Shares purchased under this Agreement,
in each case as set forth in the table on the cover page of the Prospectus
relating to such Shares. The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or

                                       5
<PAGE>
 
alleged omission to state a material fact relates to information supplied by the
Company or the Selling Stockholders on the one hand or the Underwriters on the
other and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Company, each
of the Selling Stockholders and the Underwriters agree that it would not be just
and equitable if contributions pursuant to this subsection (e) 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 which does not take account
of the equitable considerations referred to above in this subsection (e).  The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (e) shall be deemed to include 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
subsection (e), no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Shares underwritten
by it and distributed to the public were offered to the public 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 in this subsection (e) to contribute are several in proportion to
their respective underwriting obligations and not joint.

    (f)   The obligations of the Company and the Selling Stockholders under this
Section 8 shall be in addition to any liability which the Company and the
respective Selling Stockholders may otherwise have and shall extend, upon the
same terms and conditions, to each person, if any, who controls any Underwriter
within the meaning of the Act; and the obligations of the Underwriters under
this Section 8 shall be in addition to any liability which the respective
Underwriters may otherwise have and shall extend, upon the same terms and
conditions, to each officer and director of the Company and to each person, if
any, who controls the Company or any Selling Stockholder within the meaning of
the Act.

    9.    (a) If any Underwriter shall default in its obligation to purchase the
Shares which it has agreed to purchase hereunder at a Time of Delivery, you may
in your discretion arrange for you or another party or other parties to purchase
such Shares on the terms contained herein. If within thirty-six hours after such
default by any Underwriter you do not arrange for the purchase of such Shares,
then the Company and the Selling Stockholders shall be entitled to a further
period of thirty-six hours within which to procure another party or other
parties satisfactory to you to purchase such Shares on such terms. In the event
that, within the respective prescribed periods, you notify the Company that you
have so arranged for the purchase of such Shares, or the Company and the Selling
Stockholders notify you that they have so arranged for the purchase of such
Shares, you or the Company and the Selling Stockholders shall have the right to
postpone such Time of Delivery for a period of not more than seven days, in
order to effect whatever changes may thereby be made necessary in the
Registration Statement or the Prospectus, or in any other documents or
arrangements, and the Company agrees to file promptly any amendments to the
Registration Statement or the Prospectus which in your opinion may thereby be
made necessary. The term "Underwriter" as used in this Agreement shall include
any person substituted under this Section with like effect as if such person had
originally been a party to this Agreement with respect to such Shares.

    (b)   If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased does not exceed one-eleventh of
the aggregate number of all the Shares to be purchased at such Time of Delivery,
then the Company and the Selling Stockholders shall have the right to require
each

                                       6
<PAGE>
 
non-defaulting Underwriter to purchase the number of shares which such
Underwriter agreed to purchase hereunder at such Time of Delivery and, in
addition, to require each non-defaulting Underwriter to purchase its pro rata
share (based on the number of Shares which such Underwriter agreed to purchase
hereunder) of the Shares of such defaulting Underwriter or Underwriters for
which such arrangements have not been made; but nothing herein shall relieve a
defaulting Underwriter from liability for its default.

     (c) If, after giving effect to any arrangements for the purchase of the
Shares of a defaulting Underwriter or Underwriters by you and the Company and
the Selling Stockholders as provided in subsection (a) above, the aggregate
number of such Shares which remains unpurchased exceeds one-eleventh of the
aggregate number of all the Shares to be purchased at such Time of Delivery, or
if the Company and the Selling Stockholders shall not exercise the right
described in subsection (b) above to require non-defaulting Underwriters to
purchase Shares of a defaulting Underwriter or Underwriters, then this Agreement
(or, with respect to the Second Time of Delivery, the obligation of the
Underwriters to purchase and of the Company to sell the Optional Shares) shall
thereupon terminate, without liability on the part of any non-defaulting
Underwriter, the Company or the Selling Stockholders, except for the expenses to
be borne by the Company and the Selling Stockholders and the Underwriters as
provided in Section 6 hereof and the indemnity and contribution agreements in
Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from
liability for its default.

     10.  The respective indemnities, agreements, representations, warranties
and other statements of the Company, the Selling Stockholders and the several
Underwriters, as set forth in this Agreement or made by or on behalf of them,
respectively, pursuant to this Agreement, shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of any Underwriter or any controlling person of any
Underwriter, or the Company, or any of the Selling Stockholders or any officer
or director or controlling person of the Company or any controlling person of
any Selling Stockholder, and shall survive delivery of and payment for the
Shares.

     11.  If this Agreement shall be terminated pursuant to Section 9 hereof,
neither the Company nor the Selling Stockholders shall then be under any
liability to any Underwriter except as provided in Section 6 and Section 8
hereof, but, if for any other reason any Shares are not delivered by or on
behalf of the Company (with respect to the Optional Shares) and the Selling
Stockholders (with respect to the Firm Shares) as provided herein, the Company
and each of the Selling Stockholders pro rata (based on the number of Shares to
be sold by the Company and such Selling Stockholder hereunder) will reimburse
the Underwriters through GSI for all out-of-pocket expenses approved in writing
by GSI, including fees and disbursements of counsel, reasonably incurred by the
Underwriters in making preparations for the purchase, sale and delivery of the
Shares not so delivered, but the Company and the Selling Stockholders shall then
be under no further liability to any Underwriter in respect of the Shares not so
delivered except as provided in Sections 6 and 8 hereof.

     12.  In all dealings hereunder, you shall act on behalf of each of the
Underwriters, and the parties hereto shall be entitled to act and rely upon any
statement, request, notice or agreement on behalf of any Underwriter made or
given by you jointly or by GSI on behalf of you as the representatives of the
Underwriters.

    All statements, requests, notices and agreements hereunder required to be in
writing, if to the Underwriters shall be delivered or sent by mail, telex or
facsimile transmission to the Underwriters in care of GSI, Peterborough Court,
133 Fleet Street, London EC4A 2BB, England, Attention: Equity Capital Markets,
Telex No. 94012165, facsimile transmission No. (071) 774-1550; if to any Selling
Stockholder shall be delivered or sent by mail, telex or facsimile transmission
to counsel for such Selling Stockholder at its address set forth in Schedule II
hereto and if to the Company shall be

                                       7

delivered or sent by registered mail, telex or facsimile transmission to the
address of the Company set forth in the Registration Statement, Attention:
Secretary; provided, however, that any notice to an Underwriter pursuant to
Section 8(c) hereof shall be delivered or sent by mail, telex or facsimile
transmission to such Underwriter at its address set forth in its Underwriters'
Questionnaire, or telex constituting such Questionnaire, which address will be
supplied to the Company or the Selling Stockholders by GSI upon request.  Any
such statements, requests, notices or agreements shall take effect upon receipt
thereof.

     13.  This Agreement shall be binding upon, and inure solely to the benefit
of, the Underwriters, the Company and the Selling Stockholders and, to the
extent provided in Sections 8 and 10 hereof, the officers and directors of the
Company and each person who controls the Company, any Selling Stockholders or
any Underwriter, and their respective heirs, executors, administrators,
successors and assigns, and no other person shall acquire or have any right
under or by virtue of this Agreement. No purchaser of any of the Shares from any
Underwriter shall be deemed a successor or assign by reason merely of such
purchase.

     14.  Time shall be of the essence of this Agreement.

     15.  THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK, UNITED STATES OF AMERICA.

     16.  This Agreement may be executed by any one or more of the parties
hereto in any number of counterparts, each of which shall be deemed to be an
original, but all such counterparts shall together constitute one and the same
instrument.

    If the foregoing is in accordance with your understanding, please sign and
return to us one for the Company, each Selling Stockholder and one for each of
you plus one for each counsel counterparts hereof, and upon the acceptance
hereof by you, on behalf of each of the Underwriters, this letter and such
acceptance hereof shall constitute a binding agreement among each of the
Underwriters, the Company and each of the Selling Stockholders. It is understood
that your acceptance of this letter on behalf of each of the Underwriters is
pursuant to the authority set forth in a form of Agreement among Underwriters
(International Version), the form of which shall be furnished to the Company and
the Selling Stockholders for examination upon request, but without warranty on
your part as to the authority of the signers thereof.

               Re:  Culligan Water Technologies, Inc.
                    Registration Statement on Form S-3
                    ----------------------------------

Ladies and Gentlemen:

          We have acted as special counsel to Culligan Water Technologies, Inc.,
a Delaware corporation (the "Company"), in connection with (a) the public
offering by certain stockholders of the Company (the "Selling Stockholders") of
(i) 4,341,253 shares (the "Outstanding Shares") of the Company's Common Stock,
par value $.01 per share ("Common Stock"), and (ii) 653,668 shares (the "Option
Shares" and, together with the Outstanding Shares, the "Firm Shares") of Common
Stock that will be acquired upon exercise of outstanding stock options and (b)
the issuance and sale by the Company of up to 749,239 shares (the "Over-
Allotment Shares") of Common Stock to cover over-allotments in connection with
the sale of the Firm Shares.

          This opinion is being furnished in accordance with the requirements of
Item 601(b)(5) of Regulation S-K under the Securities Act of 1933 (the "Act").

          In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of (i) the Company's
Registra-
<PAGE>
 
Culligan Water Technologies, Inc.
October 4, 1996
Page 2


tion Statement on Form S-3 (Registration No. 333-12069) as filed with the
Securities and Exchange Commission (the "Commission") on September 16, 1996
under the Act and Amendment No. 1 thereto as filed with the Commission on the
date hereof (as so amended, the "Registration Statement"); (ii)  the form of
U.S. Underwriting Agreement and International Underwriting Agreement (together,
the "Underwriting Agreements") proposed to be entered into among the Company,
the Selling Stockholders, and Goldman Sachs & Co., Bear, Stearns & Co. Inc.,
NatWest Securities Limited, Smith Barney Inc. and Jefferies & Company, Inc. and
their affiliates, as representatives of the underwriters named therein (the
"Underwriters"), in each case filed as exhibits to the Registration Statement;
(iii) a specimen certificate evidencing the Common Stock; (iv) the Restated
Certificate of Incorporation of the Company, as presently in effect; (v) the
Amended and Restated By-Laws of the Company, as presently in effect; (vi) the
Stock Option Agreement, dated as of September 12, 1995, between Steven J. Green
and the Company (the "Option Agreement"); (vii) certain resolutions of the Board
of Directors of the Company and drafts of certain resolutions (the "Draft
Resolutions") of the Executive Committee of the Board of Directors of the
Company.  We have also examined originals or copies, certified or otherwise
identified to our satisfaction, of such records of the Company and such
agreements, certificates of public officials, certificates of officers or other
representatives of the Company and others, and such other documents,
certificates and records as we have deemed necessary or appropriate as a basis
for the opinions set forth herein.

          In our examination, we have assumed the legal capacity of all natural
persons, the genuineness of all signatures, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified, conformed or photostatic copies and the
authenticity of the originals of such latter documents.  In making our
examination of documents executed or to be executed by parties other than the
Company, we have assumed that such parties had or will have the power, corporate
or other, to enter into and perform all obligations thereunder and have also
assumed the due authorization by all requisite action,
<PAGE>
 
Culligan Water Technologies, Inc.

Page 3


corporate or other, and execution and delivery by such parties of such documents
and the validity and binding effect thereof.  As to any facts material to the
opinions expressed herein which we have not independently established or
verified, we have relied upon statements and representations of officers and
other representatives of the Company and others.

          In rendering the opinions set forth in paragraphs 2 and 3 below, we
have assumed that the certificates evidencing the Option Shares and the Over-
Allotment Shares will conform to the specimen certificate examined by us, will
be manually signed by an authorized officer of the transfer agent and registrar
for the Common Stock and will be duly registered by such transfer agent and
registrar.

          Members of our firm are admitted to the bar in the States of Delaware
and New York, and we do not express any opinion as to the laws of any other
jurisdiction.

          Based upon and subject to the foregoing, we are of the opinion that:

          1.  The Outstanding Shares have been duly authorized and validly
issued and are fully paid and nonassessable.

          2.  The Option Shares have been duly and validly authorized for
issuance and, when delivered and paid for in accordance with the terms of the
Option Agreement, will be validly issued, fully paid and nonassessable.

          3.  When (i) the Registration Statement becomes effective; (ii) the
Draft Resolutions have been adopted by the Executive Committee; (iii) the price
at which the Over-Allotment Shares are to be sold to the Underwriters pursuant
to the Underwriting Agreements and other matters relating to the issuance and
sale of the Over-Allotment Shares have been approved by the Executive Committee
in accordance with the Draft Resolutions; (iv) the Underwriting Agreements have
been duly executed and delivered; and (v) the Over-Allotment Shares are
delivered to and paid for by the Underwriters at a price per share not

Page 4


less than the per share par value of the Common Stock as contemplated by the
Underwriting Agreements, the issuance and sale of the Over-Allotment Shares will
have been duly authorized, and the Over-Allotment Shares will be validly issued,
fully paid and nonassessable.

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

                              Very truly yours,

                       CONSENT OF KPMG PEAT MARWICK LLP
 
The Board of Directors
Culligan Water Technologies, Inc.:
 
  We consent to the use of our report dated March 15, 1996 relating to the
Company's consolidated financial statements and schedule as of January 31,
1995 and 1996 and for each of the periods in the three year period ended
January 31, 1996 incorporated herein by reference and to the reference to our
firm under the heading "Experts" in the Prospectus.
 
  Our report contains an explanatory paragraph that states that the Company's
former parent, Astrum International Corp., was required to establish a new
basis of accounting and adjust the recorded amounts of assets and liabilities
to fair market values at June 30, 1993. The Company's consolidated financial
statements include the continuing impact of the recapitalization. As a result,
the consolidated financial statements for periods subsequent to June 30, 1993
are presented on a different cost basis than for prior periods and, therefore,
are not comparable.
