     The following summary is qualified in its entirety by the detailed
information and financial statements, including the notes thereto, appearing
elsewhere in this Prospectus. Unless otherwise indicated, the information and
share and per share data in this Prospectus (i) give effect to the Pending
Acquisitions, (ii) assume the Underwriters' over-allotment option is not

the Company's preferred stock into shares of the Common Stock.
 
                                  THE COMPANY
 
     The Company is an international provider of integrated water purification
and wastewater treatment solutions, principally to industrial and municipal
customers. The Company believes its expertise is in the analysis of a customer's
water purification and wastewater treatment requirements and the customized
application of the Company's systems, equipment and services to provide cost
effective solutions. Since its formation in December 1994, the Company has grown
significantly by completing six acquisitions consisting of thirteen operating
companies. In addition, the Company will complete the Pending Acquisitions
concurrently with the closing of the Offering. As a result of its acquisition
program and internal development, the Company has increased its ability to
provide integrated water purification and wastewater treatment solutions and has
expanded its geographic presence.
 
     The Company has developed a strategic plan to:
 
        -  Provide a full range of systems, equipment and
          services, whether independently or as part of a
          fully engineered water purification or wastewater
          treatment solution
 
        -  Pursue growth through acquisitions that:
 
          --  increase its geographic diversity
 
          --  add complementary technologies, products and
             services
 
          --  broaden its customer base and industries served
 
          --  provide strategic, synergistic and corporate
             cultural fit
 
        -  Integrate its operations and marketing strategies
          in order to maximize internal growth and increase
          profitability
 
        -  Strengthen market share for its design/build
          operations outside the United States
 
   
     As a result of the implementation of its strategic plan, the Company's pro
forma net sales for fiscal 1996 totaled $72.7 million, primarily due to its
acquisition program. In addition, the Company has begun to realize significant
improvement in internal growth rates due to the opportunities to cross-sell
systems, equipment and services and as a result of the increased financial,
managerial and other resources provided by the Company to its acquired
businesses. Pro forma net sales of the businesses acquired by the Company prior
to fiscal 1997 grew 26.3% for the six months ended March 31, 1997 compared to
the comparable period in the prior year. The Company's backlog on a pro forma
basis, consisting of written purchase orders received by the Company, was $30.0
million at May 15, 1997.
    
 
     Through its acquisition program and internal development, the Company has
established a broad distribution system both geographically and within various
markets. In fiscal 1996, 47% of the Company's pro forma net sales were derived
from customers located in the United States and Canada, 40% in Europe, 5% in
Latin America and 8% in other regions, including Asia-Pacific. Industrial
customers accounted for 60% of the
 
                                        3
<PAGE>   7
 
Company's pro forma net sales for fiscal 1996 while municipal customers
accounted for 40%. The Company's industrial customers include a broad range of
major corporations which require both purified water for their manufacturing
processes and treatment of their wastewater outflow. Industries served include
the pharmaceutical, electronic and microelectronic, pulp and paper, chemical,
petrochemical, food, beverage, automotive and other heavy manufacturing
industries. The Company serves hundreds of large and small municipal customers
worldwide which provide purified water to, and wastewater treatment for, their
communities.
 
     The global water purification and wastewater treatment industry was
estimated at $300 billion in 1995. The industry is highly fragmented and
consists of companies that design, develop and manufacture equipment, provide
engineering services, run treatment facilities and provide a combination of such
services and capabilities. The industry is composed of two primary end-markets,
municipal and industrial. In the United States, Canada and western Europe,
municipalities have responded not only to environmental regulation but also to
their constituents' awareness of the potential dangers of contaminated sources
of water and the effects of untreated wastewater on the environment. In other
areas of the world where municipalities have historically provided fewer water
and wastewater services, factors such as economic expansion, infrastructure
development, population growth and public awareness have increasingly offered
incentives for municipalities to provide such services. Within the industrial
market, corporations increasingly require sources of pure water as their
production processes become more complex and product quality standards increase.
In addition, corporations have begun treating wastewater not only in response to
government regulation but also due to the economic benefits of water reuse and
wastewater minimization in their industrial processes. Additionally, industrial
companies have increasingly outsourced their water purification and wastewater
treatment functions, eliminating much of their internal engineering capability
and expertise in an effort to reduce costs. The factors influencing both the
municipal and industrial markets are expected to propel the growth of the global
water purification and wastewater treatment industry to $500 billion by the year
2000.

                 SUMMARY SELECTED AND PRO FORMA FINANCIAL DATA
 
   
     The following table sets forth summary selected historical and unaudited
pro forma consolidated financial data of the Company since its incorporation on
December 7, 1994. The historical financial data presented for fiscal 1995 and
fiscal 1996 are derived from the audited consolidated financial statements of
the Company. The historical data presented for each of the six months ended
March 31, 1996 and 1997 are derived from unaudited financial statements which,
in the opinion of management, include all adjustments (which were of a normal
recurring nature) necessary for a fair presentation of the information set forth
therein. The historical financial data includes the operating results of each
acquired business from the date of acquisition in accordance with the purchase
method of accounting. The historical results of operations for the six months
ended March 31, 1997 are not necessarily indicative of future results. The
historical results of operations should be read in conjunction with the
financial information appearing elsewhere in this Prospectus. See "Consolidated
Financial Statements" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
    
 
   
     The unaudited pro forma financial data have been adjusted for the
acquisitions completed in fiscal 1996, the acquisition of the Nordic Group (as
defined herein) in March 1997, the Pending Acquisitions, the conversion of all
outstanding shares of the Company's preferred stock into shares of Common Stock
and the closing of the Offering and the application of the net proceeds
therefrom. The pro forma Statements of Operations Data assume that the
acquisitions completed in fiscal 1996, the acquisition of the Nordic Group and
the Pending Acquisitions were closed on October 1, 1995. The pro forma Balance
Sheet Data assume that the Pending Acquisitions were closed on March 31, 1997.
The pro forma financial information is not necessarily indicative of results the
Company would have obtained had these events actually then occurred or of the
Company's future results and should be read in conjunction with the other
financial statements and notes thereto included elsewhere in this Prospectus.

     and $646,000, respectively, for fiscal 1996, decreased net sales and gross
     profit by $4,653,000 and $1,097,000, respectively, for the six months ended
     March 31, 1996 and increased net sales and gross profit by $2,462,000 and
     $536,000, respectively, for the six months ended March 31, 1997.
    
 
   
 (2) The pro forma Statements of Operations Data include the effect of certain
     adjustments in salaries and benefits to the former owners of the companies
     acquired in fiscal 1996 and the Pending Acquisitions to levels specified in
     current employment agreements as follows: a decrease of $3,518,000 for
     fiscal 1996, and a decrease of $112,000 and $25,000 for the six months
     ended March 31, 1996 and 1997, respectively. The pro forma Statements of
     Operations Data also include the effect of certain adjustments in corporate
     office expenses to current levels as follows: an increase of $605,000 for
     fiscal 1996 and $349,000 for the six months ended March 31, 1996. In
     addition, the pro forma Statements of Operations Data include the effect of
     certain reclassifications which increased gross profit and selling, general
     and administrative expenses.
    
 
   
 (3) The pro forma financial data exclude a special charge to operations of
     approximately $2.6 million ($0.13 per share, after tax), assuming an
     initial public offering price of $11.00 per share, which will be incurred
     in the quarter in which the Offering is completed. Such charge results
     primarily from the issuance by the Company of certain compensatory stock
     options to an officer of the Company pursuant to the terms of his
     employment agreement. Of this amount, approximately $1.1 million is
     non-cash, and approximately $1.5 million represents cash payments relating
     principally to the reimbursement of income taxes resulting from this stock
     option issuance.
    
 
 (4) The pro forma Statements of Operations Data have been adjusted to reflect
     amortization of the goodwill to be recorded as a result of the acquisitions
     completed in fiscal 1996, the acquisition of the Nordic Group and the
     Pending Acquisitions over a 40 year period.
 
 (5) The pro forma Statements of Operations Data have been adjusted to reflect
     reduction of interest expense resulting from the application of estimated
     net proceeds of the Offering to repay outstanding indebtedness, as
     described in "Use of Proceeds."
 
   
 (6) Pro forma net income per share is computed by dividing net income by the
     number of shares used to compute pro forma per share data. For historical
     purposes, share data for the Company includes shares of Common Stock
     outstanding, shares of Common Stock to be issued upon the conversion of all
     outstanding Preferred Stock and the assumed exercise of outstanding stock
     options and warrants using the treasury stock method. For pro forma
     purposes, share data also includes shares of Common Stock to be issued in
     connection with the Offering and the Pending Acquisitions. Shares
     associated with options, warrants, the Offering and the Pending
     Acquisitions were computed using an assumed initial public offering price
     of $11.00 per share.
    
 
 (7) Reflects the closing of the Offering and the Company's application of the
     estimated net proceeds therefrom as described in "Use of Proceeds," and the
     conversion of all outstanding shares of the Company's preferred stock into
     shares of Common Stock.
 
   
 (8) The pro forma as adjusted Balance Sheet Data have been adjusted to reflect
     an extraordinary non-cash charge of $355,000, net of tax benefit of
     $267,000 ($0.02 per share) which will be incurred by the Company in the
     quarter in which the Offering is completed. Such charge relates to the
     write-off of unamortized debt issuance costs and discounts associated with
     certain indebtedness to be retired with net proceeds of the Offering.
    
 
   
 (9) Includes $16,644,000 of pro forma cash consideration payable in connection
     with the Pending Acquisitions to be paid from a portion of the net proceeds
     of the Offering.
    
 
   
(10) Includes $3,611,000 of pro forma consideration payable in connection with
     the Pending Acquisitions to be paid through the issuance of 328,270 shares
     of Common Stock (using an assumed initial public offering price of $11.00
     per share).

                                  RISK FACTORS
 
     Prior to making an investment decision, prospective purchasers of the
Common Stock offered hereby should consider carefully all of the information set
forth in this Prospectus and, particularly, should evaluate the following risk
factors.
 
LIMITED COMBINED OPERATING HISTORY; RISKS OF INTEGRATION
 
     Waterlink, incorporated in Delaware on December 7, 1994, has grown by
completing six acquisitions consisting of thirteen operating companies. See "The
Company." The success of the Company will depend, in part, on the Company's
ability to integrate the operations of these businesses and other companies it
acquires, including centralizing certain functions to achieve cost savings and
developing programs and processes that will promote cooperation and the sharing
of opportunities and resources among its businesses. A number of the businesses
offer different services, utilize different capabilities and technologies,
target different markets and customer segments and utilize different methods of
distribution and sales representatives. While the Company believes that there
are substantial opportunities in integrating the businesses, these differences
increase the difficulty in successfully completing such integration. In
addition, there can be no assurance that the operating results of the Company
will match or exceed the combined individual operating results achieved by the
businesses prior to their respective acquisition.
 
     Waterlink's management group has been assembled only relatively recently.
There can be no assurance that the management group will be able to oversee the
combined entity and implement the Company's operating or growth strategies
effectively. Further, to the extent that the Company is able to implement its
acquisition strategy, the resulting growth of the Company will place significant
demands on management and on the Company's internal controls. There can be no
assurance that the management group will effectively be able to direct the
Company through a period of significant growth.
 
     Further, there can be no assurance that the Company's strategy to become a
leading international provider of integrated water purification and wastewater
treatment solutions will be successful, or that the Company's targeted client
segments will accept the Company as a provider of such solutions. See "Business"
and "Management."
 
DEPENDENCE ON ACQUISITIONS FOR GROWTH
 
     The Company intends to grow primarily by acquiring existing businesses.
This acquisition strategy involves risks inherent in assessing the values,
strengths, weaknesses, risks and profitability of acquisition candidates,
including adverse short-term effects on the Company's reported operating
results, diversion of management's attention, dependence on retaining, hiring
and training key personnel, and risks associated with unanticipated problems or
latent liabilities. Although the Company generally has been successful in
acquiring companies it has pursued, there can be no assurance that acquisition
opportunities will continue to be available, that the Company will have access
to the capital required to finance potential acquisitions, that the Company will
continue to acquire businesses or that any business acquired by the Company will
be integrated successfully into the Company's operations and prove profitable.
In addition, to the extent that consolidation becomes more prevalent in the
industry, the prices for attractive acquisition candidates may be bid up to
higher levels and there can be no assurance that businesses acquired in the
future will achieve sales and profitability that justify the investment therein.
See "The Company" and "Business."
 
NEED FOR ADDITIONAL ACQUISITION FINANCING
 
     The Company currently intends to use a combination of shares of its Common
Stock, cash, and debt obligations in making future acquisitions. The extent to
which the Company will be able or willing to use the Common Stock for this
purpose will depend on its market value from time to time and the willingness of
potential sellers of acquisition targets to accept it as full or partial
payment. To the extent the Company is unable to use the Common Stock to make
future acquisitions, its ability to grow may be limited by the extent to which
it is able to raise capital for this purpose, as well as to expand existing
operations, through debt or additional equity financing. The Company has $25
million in the aggregate available to it, subject to certain
 
                                        7
<PAGE>   11
 
borrowing base requirements, under bank credit facilities (the "Credit
Facility") underwritten by certain financial institutions, with Bank of America
Illinois (the "Bank") as Agent and two of the Bank's foreign affiliates, to be
used for acquisitions, working capital and other corporate purposes. No
assurance can be given the Company will be able to obtain the capital it would
need to finance a successful acquisition program and its other cash needs. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS OF OPERATIONS
 
     The Company has in the past experienced quarterly fluctuations in operating
results due to the contractual nature of its business and, to a lesser extent,
weather conditions. As part of its strategic plan and due to the Pending
Acquisitions, the Company expects that in the future it may receive contracts
that are significantly larger than those received by the Company historically.
In addition, certain of such contracts will be subject to the customer's ability
to finance, or fund from government sources, the actual costs of completing the
project as well as receiving any necessary permits. Therefore, the Company
expects that its future operating results could fluctuate significantly,
especially on a quarterly basis, due to the timing of the awarding of such
contracts, the ability to fund project costs, and the recognition by the Company
of revenues and profits therefrom. In addition, the Company has historically
operated with a moderate backlog. As a result, quarterly sales and operating
results depend in part on the volume and timing of contracts received and
performed within the quarter, which are difficult to forecast. Any significant
deferral or cancellation of a contract could have a material adverse effect on
the Company's operating results in any particular period. Accordingly, the
Company believes that period-to-period comparisons of its operating results may
not be necessarily indicative of future performance. As a result, the Company's
operating results and stock price could prove to be volatile, particularly on a
quarterly basis.
 
OPERATIONS OUTSIDE THE UNITED STATES
 
     A substantial proportion of the Company's systems, equipment and services
are sold in western Europe, Latin America and other regions outside the United
States and a number of the Company's subsidiaries operate outside of the United
States. On an annualized pro forma basis (assuming the Pending Acquisitions are
completed), the Company's net sales outside the United States were approximately
61% of its pro forma fiscal 1996 net sales. Such sales pose certain risks
associated with doing business in foreign countries, resulting from certain
political, economic and other uncertainties, including, among others, risks of
war, expropriation or nationalization of assets, renegotiation or nullification
of existing contracts, changing political conditions, changing laws and policies
affecting trade and investment, overlap of different tax structures, and the
general hazards associated with the assertion of sovereignty over certain areas
in which operations are conducted. Additionally, various jurisdictions have laws
limiting the right and ability of subsidiaries and joint ventures to pay
dividends and remit earnings to affiliated companies, unless specified
conditions are satisfied.
 
     Certain aspects of the Company's operations are subject to governmental
regulations in the countries in which the Company operates, including those
relating to currency conversion and repatriation, taxation of its earnings and
earnings of its personnel, and its use of local employees and suppliers. The
Company's operations are also subject to the risk of changes in laws and
policies in the various jurisdictions in which the Company operates which may
impose restrictions on the Company, including trade restrictions, that could
have a material adverse effect on the Company's business, financial condition
and results of operations. Other types of government regulation which could, if
enacted or implemented, materially and adversely affect the Company's operations
include expropriation or nationalization decrees, confiscatory tax systems,
primary or secondary boycotts directed at specific countries or companies,
embargoes and import restrictions or other trade barriers. The Company cannot
determine to what extent future operations and earnings of the Company may be
affected by new laws, new regulations, changes in or new interpretations of
existing laws or regulations or other consequences of doing business outside the
United States.
 
                                        8
<PAGE>   12
 
FOREIGN CURRENCY RISKS
 
     Because the Company's functional currency is the United States dollar, its
operations outside the United States sometime face the additional risks of
fluctuating currency values and exchange rates, hard currency shortages and
controls on currency exchange. The Company has operations outside the United
States and is hedged, to some extent, from foreign exchange risks because of its
ability to purchase, manufacture and sell in the local currency of those
jurisdictions. In addition, the Company does enter into foreign currency
contracts under certain circumstances to reduce the Company's exposure to
foreign exchange risks. There can be no assurance, however, that the attempted
matching of foreign currency receipts with disbursements or hedging activity
will adequately moderate the risk of currency or exchange rate fluctuations
which could have a material adverse effect on the Company's business, financial
condition and results of operations. In addition, to the extent the Company has
operations outside the United States, the Company is subject to the impact of
foreign currency fluctuations and exchange rate charges on the Company's
reporting in its financial statements of the results from such operations
outside the United States. Since such financial statements are prepared
utilizing United States dollars as the basis for presentation, results from any
operations outside the United States reported in the financial statements must
be restated into dollars utilizing the appropriate foreign currency exchange
rate, and thereby subjecting such results to the impact of currency and exchange
rate fluctuations. See "Business."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's operations depend on the continuing efforts of its executive
officers and its senior management, in particular Theodore F. Savastano,
Waterlink's Chairman; Chet S. Ross, Waterlink's President and Chief Executive
Officer; and the presidents of each of the operating subsidiaries. Should the
Company be unable to retain any of its executive officers or senior management,
the Company's prospects could be adversely affected. In addition, the Company
intends to grow through acquisitions and internal expansion. The Company likely
will depend on the senior management of any significant businesses it acquires
in the future and on its ability to attract qualified management to support its
internal expansion. The business or prospects of the Company could be affected
adversely if any of these senior management of acquired businesses does not
continue in his or her management role after joining the Company and if the
Company is unable to attract and retain qualified replacements and additional
members of management. See "Management."
 
COMPETITION
 
     The water purification and wastewater treatment industry is fragmented and
highly competitive due to the large number of businesses within certain product
areas. The Company competes with many companies, several of which have greater
market penetration, depth of product line, resources and access to capital,
which could be competitive advantages in securing certain projects. While the
Company believes it is well positioned to deliver technology and services at a
fair price, some competitors have developed product and service integration
capabilities beyond the current scope of the Company. In addition, some
competitors may have greater financial resources than the Company to finance
acquisition and internal growth opportunities. Consequently, the Company may
encounter significant competition in its efforts to achieve its objectives. See
"Business -- Competition."
 
CYCLICALITY OF DEMAND FOR WATER PURIFICATION AND WASTEWATER EQUIPMENT
 
     Much of the water purification and wastewater equipment sold by the Company
requires significant capital expenditures by its customers. As such, the timing
of customer purchases may be affected by various economic factors, including
interest rate and business cycle fluctuations, which are beyond the control of
the Company. While the Company sells equipment across a broad cross section of
industry segments and customers, the cyclical nature of capital equipment sales
could have an adverse effect on the its revenues and profitability in general,
and on the its revenues and profitability in any individual financial reporting
period.
 
                                        9
<PAGE>   13
 
POTENTIAL ENVIRONMENTAL LIABILITIES
 
     In the United States, the Comprehensive Environmental Response,
Compensation, and Liability Act of 1980, as amended ("CERCLA" or "Superfund"),
and comparable state laws, impose joint and several liability without fault for
the releases of hazardous substances into the environment. Potentially
responsible parties include (i) owners and operators of the site, (ii) parties
which create the hazardous substances released at the site, and (iii) parties
which arrange for the transportation or disposal of such hazardous substances.
The Company is also subject to applicable environmental laws in countries
outside the United States where it operates or in which its customers are
located. These requirements and their enforcement may vary by country but in
general prescribe standards for the protection of human health, safety and the
environment. The Company could face claims by governmental authorities, private
individuals and other persons alleging that hazardous substances were released
during the treatment process or from the use or disposal of end products and
by-products in violation of applicable law.
 
RELIANCE ON ENVIRONMENTAL REGULATION
 
     Federal, state, local and foreign environmental laws and regulations impose
substantial standards for properly purifying water and treating wastewater, and
impose liabilities for noncompliance. Environmental laws and regulations are,
and will continue to be, a significant factor affecting the marketability of the
Company's solutions, systems and equipment. To the extent that demand for the
Company's solutions, systems and equipment is created by the need to comply with
such environmental laws and regulations, any modification of the standards
imposed by such laws and regulations may reduce demand, thereby adversely
affecting the Company's business and prospects. The relaxation or repeal of any
such laws or regulations or the strict enforcement thereof could adversely
affect the Company's business and prospects. See "Business -- Government
Regulation."
 
PROCESS AND PRODUCT WARRANTY AND PERFORMANCE GUARANTEES
 
     In connection with providing certain services and products to its
customers, the Company sometimes is required to guarantee that the services and
products will attain specified levels of quality or performance. Should a
product fail to perform according to a performance guarantee, or should a
service fail to accomplish treatment levels which are guaranteed, and should the
Company be unable to remedy such failure within any applicable cure period, the
Company could incur financial penalties in the form of liquidated damages or
could be required to remove and/or replace the equipment or repeat the service
in order to meet the specifications. While the Company historically has
fulfilled all of its guarantee obligations, there can be no assurance the
Company will be able to fulfill its future guarantee obligations or that
fulfilling such obligations may not involve material costs that could have a
material adverse effect on the Company. See "Business -- Process and Product
Warranty and Performance Guarantees."
 
DIVIDEND POLICY; RESTRICTIONS ON PAYMENT OF DIVIDENDS
 
     The Company currently intends to retain earnings to provide funds for the
operation and expansion of its business and, accordingly, does not anticipate
paying cash dividends in the foreseeable future. The Company's Credit Facility
prohibits the payment of dividends without the consent of the Bank. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
POTENTIAL EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE ON PRICE OF COMMON STOCK
 
   
     On closing of the Offering, 10,932,554 shares of Common Stock will be
outstanding. The 4,500,000 shares sold in the Offering (other than shares that
may be purchased by affiliates of the Company) will be freely tradable. The
remaining shares outstanding may be resold publicly only following their
effective registration under the Securities Act of 1933, as amended (the
"Securities Act"), or pursuant to an available exemption (such as provided by
Rule 144 following a holding period for previously unregistered shares) from the
registration requirements of the Securities Act. Substantially all of the
holders of those remaining shares
    
 
                                       10
<PAGE>   14
 
   
have certain rights to have their shares registered in the future under the
Securities Act (see "Shares Eligible for Future Sale"). The Company, its
officers and directors, and the holders of substantially all of the Common Stock
have agreed that, until the later of December 31, 1997 or 180 days following the
date of this Prospectus (the "Lockup Period"), they will not, without the prior
written consent of Smith Barney Inc., offer, sell, contract to sell or otherwise
dispose of any shares of Common Stock, or any securities convertible into, or
exercisable or exchangeable for, Common Stock, except that the Company may grant
warrants pursuant to the Note Purchase Agreement and grant options under the
Company's stock option and stock purchase plans, and may issue shares of Common
Stock (i) in connection with acquisitions, (ii) pursuant to the exercise of
options granted under the Company's stock option and stock purchase plans, (iii)
pursuant to the exercise of warrants outstanding as of the closing of the
Offering or which the Company is obligated to issue as part of the 1997
Warrants, (iv) pursuant to the conversion of the Company's preferred stock and
(v) pursuant to or in connection with the Company's Rights Plan. Sales made
pursuant to Rule 144 must comply with its applicable volume and manner of sale
limitations and other requirements. Absent additional offerings that are
registered under the Securities Act and any additional issuances of Common Stock
not referred to below, it is anticipated that as many as 6,317,554 shares of
Common Stock may be eligible to be sold pursuant to Rule 144 within
approximately one year of the closing of the Offering, of which approximately
1,855,000 shares of Common Stock may be immediately eligible to be sold (subject
to the Lockup Period).
    
 
   
     On closing of the Offering, the Company also will have outstanding options
to purchase up to a total of 1,472,800 shares of Common Stock. The Company
intends to register all the shares subject to these options under the Securities
Act for public resale. See "Management -- Benefit Plans."
    
 
   
     In addition, the Company will have outstanding warrants to purchase 350,000
shares of Common Stock (subject to adjustment). Pursuant to the applicable
warrant agreements, the holders of such warrants have certain rights to require
the Company to register the shares of Common Stock to be issued upon exercise of
the warrants. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Liquidity and Capital Resources"; "Certain
Transactions -- 1997 Notes, 1997 Warrants and Stockholder Guarantee" and
"Description of Capital Stock -- 1997 Warrants."
    
 
   
     The Company intends to register 5,000,000 additional shares of Common Stock
under the Securities Act during the fourth quarter of fiscal 1997 for its use in
connection with future acquisitions. These shares generally will be freely
tradable after their issuance by persons not affiliated with the Company, unless
the Company is able to contractually restrict their resale. Sales of these
shares during the Lockup Period would require the prior written consent of Smith
Barney Inc.
    
 
   
     Assuming no additional options or warrants to purchase shares of Common
Stock, and no additional shares of Common Stock (other than upon the exercise of
currently outstanding options or warrants) are issued, approximately 6,317,554
shares of Common Stock (in addition to the shares offered in the Offering) could
be traded within one year of the closing of the Offering, of which approximately
1,855,000 shares of Common Stock may be immediately eligible to be sold (subject
to the Lockup Period referred to above). The effect, if any, that the
availability for sale, or sale, of the shares of Common Stock eligible for
future sale will have on the market price of the Common Stock prevailing from
time to time is unpredictable, and no assurance can be given that the effect
will not be adverse.
    
 
   
NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
    
 
   
     Prior to the Offering, no public market for the Common Stock has existed,
and the initial public offering price, which has been determined by negotiation
between the Company and representatives of the Underwriters, may not be
indicative of the price at which the Common Stock will trade after the Offering.
See "Underwriting" for the factors considered in determining the initial public
offering price. The Common Stock has been approved for listing on The New York
Stock Exchange, subject to official notice of listing, but no assurance can be
given that if so listed, an active trading market for the Common Stock will
develop or, if developed, that it will continue after the Offering. The market
price of the Common Stock after the Offering may be subject to significant
fluctuations from time to time in response to numerous factors, including
variations in the reported annual and quarterly financial results of the
Company, changes in financial
    
 
                                       11
<PAGE>   15
 
projections or failures by the Company to meet such projections and changing
conditions in the economy in general or in the Company's industry in particular.
In addition, the stock markets experience significant price and volume
volatility from time to time which may affect the market price of the Common
Stock for reasons unrelated to the Company's performance at that time.
 
POTENTIAL ANTI-TAKEOVER EFFECTS
 
     Upon the closing of the Offering, the Company will have adopted a
stockholder rights plan. The plan and provisions of the Company's Certificate of
Incorporation, as amended (the "Company Certificate"), the Company's Bylaws, as
amended (the "Company Bylaws"), and the Delaware General Corporation Law (the
"DGCL") may have the effect of delaying, discouraging, inhibiting, preventing or
rendering more difficult an attempt to obtain control of the Company by means of
a tender offer, business combination, proxy contest or otherwise. These
provisions include the charter authorization of "blank check" preferred stock,
classification of the Board of Directors, a restriction on the ability of
stockholders to take actions by written consent, a "fair price" provision and a
DGCL provision imposing restrictions on business combinations with certain
interested parties. See "Description of Capital Stock."
 
OWNERSHIP AND CONTROL BY CERTAIN SHAREHOLDERS
 
   
     Upon the closing of the Offering, on a fully diluted basis and assuming the
vesting and exercise of all outstanding options and the conversion of all issued
and outstanding shares of preferred stock, the Company's directors and
management will own or control approximately 33.5% of the Company's outstanding
voting capital stock. Collectively, such shareholders may be able to effectively
control decisions of the Company, as the Company Certificate, and the Company
By-laws generally require a majority vote of holders of the outstanding shares
of the Company to authorize actions of the Company. This concentration of
ownership by directors and management may also have the effect of delaying or
preventing a change in control of the Company. See "Security Ownership" and
"Description of Capital Stock."
    
 
DILUTION
 
   
     Purchasers of Common Stock in the Offering (i) will experience immediate
and substantial dilution in the net tangible book value of their stock of $8.93
per share (see "Dilution") and (ii) may experience further dilution in that
value from issuances of Common Stock in connection with future acquisitions. In
addition, dilution may occur upon exercise of outstanding stock options or
warrants, and/or the Company may reserve additional shares of Common Stock in
the future for issuance under stock option or other incentive employee
compensation plans. The Board of Directors of the Company has the legal power
and authority to determine the terms of an offering of shares of the Company's
capital stock (or securities convertible into or exchangeable for such shares),
to the extent of the Company's shares of authorized and unissued capital stock.
See "Dilution" and "Description of Capital Stock."
    
 
FORWARD-LOOKING STATEMENTS
 
     With the exception of historical information, the matters discussed in this
Prospectus may include forward-looking statements that involve risks and
uncertainties. While forward-looking statements are sometimes presented with
numerical specificity, they are based on variety of assumptions made by
management regarding future circumstances over which the Company has little or
no control. A number of important factors, including those identified in this
section as well as factors discussed elsewhere in this Prospectus, could cause
the Company's actual results to differ materially from those in forward-looking
statements or financial information. Actual results may differ from
forward-looking results for a number of reasons, including the following: (i)
changes in world economic conditions (including, but not limited to, the
potential instability of governments and legal systems in countries in which the
Company conducts business, and significant changes in currency valuations), (ii)
changes in customer demand as they affect sales and product mix (including, but
not limited to, the effect of strikes at customers' facilities, variations in
backlog and the impact of changes in industrial business cycles), (iii)
competitive factors (including, but not limited to, changes in market
penetration and the introduction of new products by existing and new
competitors), (iv) changes in operating costs (including, but not limited to,
the effect of changes in the Company's
 
                                       12
<PAGE>   16
 
manufacturing processes; changes in costs associated with varying levels of
operations; changes resulting from different levels of customers demands; the
effects of unplanned work stoppages; changes in cost of labor and benefits; and
the cost and availability of raw materials and energy), (v) the success of the
Company's operating plan (including, but not limited to, its ability to achieve
the total planned benefits of its strategic plan, its ability to integrate
acquisitions into Company operations, and the ability of recently acquired
companies to meet satisfactory operating results), and (vi) unanticipated
litigation, claims or assessments (including, but not limited to, claims or
problems related to product warranty and environmental issues).

                                  THE COMPANY
 
   
GENERAL
    
 
   
     Waterlink was incorporated in Delaware on December 7, 1994 in order to
participate in the consolidation of the highly fragmented water purification and
wastewater treatment industry. The Company has begun executing this strategy
through an acquisition program which targets businesses in four markets:
industrial process water, industrial wastewater, municipal drinking water and
municipal wastewater. The Company was initially capitalized by the purchase of
shares of Common Stock and Series A Preferred Stock by Brantley Venture Partners
III, L.P. (400,000 shares of Common Stock and 400,000 shares of Series A
Preferred Stock) and by Theodore F. Savastano, the Company's Chairman (800,000
shares of Common Stock), for an aggregate investment of $501,200. From its
incorporation in December 1994 until its first acquisition in March 1995, the
Company focused on initial formation activities, attracting certain initial
employees and pursuing its analysis of potential acquisition candidates. In
March 1995, the Company acquired the assets of Sanborn Inc. (doing business as
Sanborn Technologies ("Sanborn Technologies")). Sanborn Technologies is a
designer and builder of industrial separation systems which are used by
customers for environmental compliance, resource conservation and production
processes. Later in fiscal 1995, the Company acquired Great Lakes Environmental,
Inc. ("Great Lakes"), which enabled the Company to enter the industrial
wastewater market. Great Lakes is a designer and builder of industrial
wastewater pretreatment systems and custom high quality oil/water separation
products.
    
 
   
     In fiscal 1996, Waterlink completed three acquisitions, comprised of the
assets of Mass Transfer Systems, Inc. ("Mass Transfer"), the assets of Aero-Mod
Incorporated and its affiliates ("Aero-Mod") and the capital stock of Water
Equipment Technologies, Inc. (now known as Waterlink Technologies, Inc.
("Waterlink Technologies")). The acquisition of Mass Transfer provided access to
additional technologies used primarily in the industrial wastewater market and,
to a lesser extent, in the municipal wastewater market. Mass Transfer is a
designer of customized jet aeration and jet mixing systems used to accelerate
the biological digestion process through the introduction of oxygen in the
treatment of wastewater. The acquisition of Aero-Mod expanded the Company's
presence in the municipal wastewater market and presented cross-selling
opportunities with Mass Transfer. Additionally, Aero-Mod expanded the Company's
geographic presence and scope of operations through its customer base outside of
the United States, especially in Latin America, and its contract operations
business. Aero-Mod designs wastewater treatment plants, provides clarifiers,
slide rail diffusers, filters and dewatering equipment for the biological
treatment of wastewater and biosolids and provides contract operation services.
The acquisition of Waterlink Technologies enabled the Company to enter the
industrial process water and municipal drinking water markets and increased the
Company's presence in markets outside the United States. Waterlink Technologies
is a designer and builder of water treatment filters and membrane separation
systems, including reverse osmosis systems, and related treatment equipment. Pro
forma fiscal 1996 net sales relating to the companies acquired in fiscal 1995
and fiscal 1996 totaled $33.1 million.
    
 
   
     During fiscal 1997 to date, Waterlink acquired the capital stock of the
Nordic Water Products Group subsidiaries (the "Nordic Group"). The Nordic Group
provided the Company with numerous benefits including a distribution channel for
its existing businesses into Europe; internationally recognized and accepted
technologies and equipment used in both the municipal and industrial markets;
and the Company's first substantial design/build operations, focused primarily
in Europe. The Nordic Group manufactures continuous recirculating sand filters,
inclined plate settlers and systems for nutrient removal, decanting centrifuges
for dewatering biosolids and hydraulic surface and bottom scrapers. The Nordic
Group also installs mechanical and electrical systems and designs and builds
water purification and wastewater treatment plants in Europe. Pro forma fiscal
1996 net sales relating to the Nordic Group totaled $29.4 million.
    
 
   
     Simultaneously with the closing of the Offering, Waterlink will acquire the
capital stock of Bioclear and Lanco. Bioclear provides the Company with access
to sequential batch reactor technology, which expands its ability to treat
industrial and municipal wastewater biologically. The Company believes that this
technology presents various cross-selling opportunities, particularly with
Aero-Mod, Mass Transfer, Waterlink Technologies and the Nordic Group.
Additionally, Bioclear enhances the Company's design/build capabilities. Lanco
    
 
                                       14
<PAGE>   18
 
   
expands the Company's product offerings in the industrial wastewater treatment
market and is complementary with Great Lakes. Lanco fabricates small plate and
frame filter presses for dewatering biosolids and inclined plate clarifiers for
heavy metal removal. Pro forma fiscal 1996 net sales relating to the Pending
Acquisitions totaled $10.2 million.
    
 
   
     Primarily due to its acquisition program, the Company's pro forma net sales
for fiscal 1996 totaled $72.7 million. In addition, the Company has begun to
realize significant improvement in internal growth rates due to the
opportunities to cross-sell systems, equipment and services and as a result of
the increased financial, managerial and other resources provided by the Company
to its acquired businesses. For example, subsidiaries selling wastewater
treatment systems now have the ability to offer both aeration and mixing systems
and subsidiaries selling water treatment systems can now offer wastewater
treatment systems for the same projects. Additionally, the Company's
design/build capabilities allow it to design systems that utilize a broad array
of the Company's products and provide opportunities for its contract operation
services. The Company also experiences cross-selling opportunities from a
geographic and customer standpoint. For example, the Company believes that it
should benefit from the recent acquisition of the Nordic Group both from the
Nordic Group's ability to introduce the Company's existing systems, equipment
and services into the European market and from the Company's ability to
introduce the Nordic Group's systems, equipment and services into the Company's
existing markets. Pro forma net sales of the businesses acquired by the Company
prior to fiscal 1997 grew 26.3% for the six months ended March 31, 1997 compared
to the comparable period in the prior year.
    
 
     Since December 7, 1994, the Company has developed the core competencies
required to provide integrated water purification and wastewater treatment
solutions to both industrial and municipal customers. The Company intends to
continue its acquisition program in order to provide the Company with additional
complementary systems, equipment and services, broaden its customer and
geographic base and enhance the Company's design/build capabilities.
 
   
SUMMARY OF PRINCIPAL TERMS OF THE PENDING ACQUISITIONS
    
 
   
     Simultaneously with the closing of the Offering, the Company will purchase
all of the outstanding shares of capital stock of Bioclear for an aggregate
consideration consisting of (i) $20,000,000 (Canadian) in cash payable at or
prior to the closing, (ii) $5,000,000 (Canadian) in shares of Common Stock
valued at the initial public offering price payable at the closing, (iii) up to
an additional $5,000,000 (Canadian) in cash payable with respect to periods
ending in 1998, 1999 and 2000 pursuant to an earn-out provision and (iv)
additional cash payable with respect to periods ending in 1999 and 2000 pursuant
to certain additional purchase consideration provisions, all as set forth in the
purchase agreement. Of the $20,000,000 (Canadian) in cash payable at or prior to
the closing, $2,000,000 is to be paid into escrow to secure the sellers'
indemnification obligations under the purchase agreement. The earn-out and
additional purchase consideration provisions of the purchase agreement are based
on Bioclear's earnings before interest and taxes, as adjusted in accordance with
the purchase agreement, for the applicable periods. Under the earn out
provision, the sellers would be entitled to a fixed percentage of such adjusted
earnings in excess of an earnings target, with an aggregate maximum earn out
payment of $5,000,000 (Canadian). Under the additional purchase consideration
provisions, the sellers would be entitled to a smaller fixed percentage of such
adjusted earnings in excess of a higher earnings target. Since such additional
purchase consideration payments, if any, are based on a fixed percentage of such
excess amount, there is no maximum amount for such payments. In addition, if the
Bioclear acquisition is not completed before June 30, 1997, Bioclear is
permitted to pay to its current stockholders a dividend up to the amount by
which stockholders' equity of Bioclear exceeds $910,620 (Canadian) at the
closing date of the acquisition.
    
 
   
     The Company will purchase all of the outstanding shares of stock of Lanco
for an aggregate purchase price of $2,200,000 payable in cash at or prior to the
closing. Of this amount, $100,000 is to be paid into escrow to secure the
seller's indemnification obligations under the purchase agreement.
    
 
   
     The consideration being paid by the Company for each of Bioclear and Lanco
was determined by arm's-length negotiations between the applicable parties. The
closing of each of the Pending Acquisitions is subject
    
 
                                       15
<PAGE>   19
 
   
to customary conditions. These conditions include, among other things, the
accuracy on the closing dates of the representations and warranties made by the
respective sellers, the performance by the respective parties of each of the
applicable covenants included in the purchase agreements, and the nonexistence
of a material adverse change in the business, assets, liabilities, results of
operations or prospects of Bioclear or Lanco, as the case may be. Each purchase
agreement may be terminated, under certain circumstances (i) by mutual consent
of the parties, (ii) by the Company if a material misrepresentation or breach in
representations and warranties by sellers occurs, or if a material portion of
the assets of Bioclear or Lanco, as the case may be, are materially damaged or
destroyed, or (iii) by either party if the conditions to such party's
obligations to consummate the closing of the acquisition have not been
satisfied.
    
 
     The Company's executive offices are located at 4100 Holiday Street, N.W.,
Suite 201, Canton, Ohio 44718-7532 and its telephone number is (330) 649-4000.
 
                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby (based upon an assumed public offering price of $11.00 per
share), after deducting underwriting discounts and commissions and estimated
offering expenses payable by the Company, are estimated to be approximately
$43.8 million (approximately $50.7 million if the Underwriters exercise their
over-allotment option in full). Of the net proceeds, approximately $16.6 million
will be used to pay the cash portion of the purchase prices for the Pending
Acquisitions, approximately $26.8 million will be used concurrently for the
repayment of outstanding indebtedness of the Company and the remainder will be
used for general working capital purposes. See "Certain Transactions."
    
 
   
     The indebtedness to be repaid from the proceeds of the Offering bears
interest at rates ranging from 3.9% to 10.6% and was incurred to fund completed
acquisitions and for working capital requirements. Such indebtedness would
otherwise mature at various dates through April 2002.
    
 
                                DIVIDEND POLICY
 
     The Company has not declared or paid any cash dividends on its Common
Stock. It is the Company's current intention to retain earnings to finance the
expansion of its business. Any future dividends will be at the discretion of the
Board of Directors after taking into account various factors, including, among
others, the Company's financial condition, results of operations, cash flows
from operations, current and anticipated cash needs and expansion plans, the
income tax laws then in effect, the requirements of Delaware law, the
restrictions imposed under the Credit Facility and the 1997 Notes (as defined
below) and any restrictions that may be imposed by the Company's future credit
facilities and other indebtedness. The Company's Credit Facility prohibits its
payment of dividends without the consent of the Bank. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Liquidity and Capital Resources."

     the Company's 1995 Stock Option Plan, (ii) 75,000 shares subject to other
     outstanding options to purchase Common Stock, 40,000 of which were
     exercised in April 1997, (iii) 225,000 shares issuable upon exercise of a
     warrant issued to the Bank, and (iv) 125,000 shares (subject to adjustment)
     issuable upon exercise of warrants issued in connection with commitments to
     purchase subordinated indebtedness of the Company. See "Management's
     Discussion and Analysis of Financial Condition and Results of Operations --

 (2) Includes $3,611,000 of pro forma consideration payable in connection with

     quarter in which the Offering is completed. Such charge relates to the
     write-off of unamortized debt issuance costs and discounts associated with
     certain indebtedness to be retired with net proceeds of the Offering.

                                    DILUTION
 
   
     The deficit in pro forma net tangible book value of the Company as of March
31, 1997 was approximately $20,855,000, or approximately $3.26 per share, after
giving effect to the Pending Acquisitions. The deficit in pro forma net tangible
book value per share represents the amount by which the Company's pro forma
total liabilities exceed the Company's pro forma net tangible assets as of March
31, 1997, divided by the number of shares of Common Stock to be outstanding
after giving effect to (i) the Pending Acquisitions and (ii) the conversion of
all outstanding shares of the Company's preferred stock into shares of Common
Stock. After giving effect to the sale of the 4,500,000 shares offered hereby
(at an assumed public offering price of $11.00 per share) and after deducting
estimated underwriting discounts and commissions and estimated offering expenses
payable by the Company, the Company's pro forma net tangible book value as of
March 31, 1997 would have been approximately $22,575,000, or approximately $2.07
per share. This represents an immediate increase in pro forma net tangible book
value of approximately $5.33 per share to existing shareholders and an immediate
dilution of approximately $8.93 per share to new investors purchasing shares in
the Offering at the assumed public offering price per share. The following table
illustrates this pro forma per share dilution:

 (1) Pro forma net sales and gross profit have been adjusted to recognize
     revenue on the percentage of completion method of accounting at an acquired
     company which previously recognized revenue on the completed contract
     method. This adjustment decreased net sales and gross profit by $2,715,000
     and $646,000, respectively, for fiscal 1996, decreased net sales and gross
     profit by $4,653,000 and $1,097,000, respectively, for the six months ended
     March 31, 1996, and increased net sales and gross profit by $2,462,000 and
     $536,000, respectively, for the six months ended March 31, 1997.
    
 
   
 (2) The pro forma Statements of Operations Data include the effect of certain
     adjustments in salaries and benefits to the former owners of the companies
     acquired in fiscal 1996 and the Pending Acquisitions to levels specified in
     current employment agreements as follows: a decrease of $3,518,000 for
     fiscal 1996, and a decrease of $112,000 and $25,000 for the six months
     ended March 31, 1996 and 1997, respectively. The pro forma Statements of
     Operations Data also include the effect of certain adjustments in corporate
     office expenses to current levels as follows: an increase of $605,000 for
     fiscal 1996 and $349,000 for the six months ended March 31, 1996. In
     addition, the pro forma Statements of Operations Data include the effect of
     certain reclassifications which decreased cost of sales and increased
     selling, general and administrative expenses.
    
 
   
 (3) The pro forma financial data exclude a special charge to operations of
     approximately $2.6 million ($0.13 per share, after tax), assuming an
     initial public offering price of $11.00 per share, which will be incurred
     in the quarter in which the Offering is completed. Such charge results
     primarily from the issuance by the Company of certain compensatory stock
     options to an officer of the Company pursuant to the terms of an employment
     agreement. Of this amount, approximately $1.1 million is non-cash, and
     approximately $1.5 million represents cash payments relating principally to
     the reimbursement of income taxes resulting from this stock option
     issuance.
    
 
 (4) The pro forma Statements of Operations Data have been adjusted to reflect
     amortization of the goodwill to be recorded as a result of the acquisitions
     completed in fiscal 1996, the acquisition of the Nordic Group and the
     Pending Acquisitions over a 40 year period.

 (5) The pro forma Statements of Operations Data have been adjusted to reflect
     reduction of interest expense resulting from the application of estimated
     net proceeds of the Offering to repay outstanding indebtedness, as
     described in "Use of Proceeds."
    
 
   
 (6) Pro forma net income per share is computed by dividing net income by the
     number of shares used to compute pro forma per share data. For historical
     purposes, share data for the Company includes shares of Common Stock
     outstanding, shares of Common Stock to be issued upon the conversion of all
     outstanding Preferred Stock and the assumed exercise of outstanding stock
     options and warrants using the treasury stock method. For pro forma
     purposes, share data also includes shares of Common Stock to be issued in
     connection with the Offering and the Pending Acquisitions. Shares
     associated with options, warrants, the Offering and the Pending
     Acquisitions were computed using an assumed initial public offering price
     of $11.00 per share.
    
 
   
 (7) Reflects the closing of the Offering and the Company's application of the
     estimated net proceeds therefrom as described in "Use of Proceeds," and the
     conversion of all outstanding shares of the Company's preferred stock into
     shares of Common Stock.
    
 
   
 (8) The pro forma as adjusted Balance Sheet Data have been adjusted to reflect
     an extraordinary non-cash charge of $355,000, net of tax benefit of
     $267,000 ($0.02 per share) which will be incurred by the Company in the
     quarter in which the Offering is completed. Such charge relates to the
     write-off of unamortized debt issuance costs and discounts associated with
     certain indebtedness to be retired with net proceeds of the Offering.
    
 
   
 (9) Includes $16,644,000 of pro forma cash consideration payable in connection
     with the Pending Acquisitions to be paid from a portion of the net proceeds
     of the Offering.
    
 
   
(10) Includes $3,611,000 of pro forma consideration payable in connection with
     the Pending Acquisitions to be paid through the issuance of 328,270 shares
     of Common Stock (using an assumed initial public offering price of $11.00
     per share).

OVERVIEW
 
   
     The Company is an international provider of integrated water purification
and wastewater treatment solutions, principally to industrial and municipal
customers. Waterlink was incorporated in Delaware on December 7, 1994 and has
grown through numerous acquisitions. The Company's acquisitions have enabled it
to build its technical capabilities and geographical presence. Through March 31,
1997, the Company had completed the following six acquisitions at the following
effective dates:

            - Nordic Group.................................    March 5, 1997
</TABLE>
    
 
   
     The Company will complete the Pending Acquisitions simultaneously with the
completion of the Offering.
    
 
     As part of its strategic plan, the Company intends to continue an
aggressive acquisition program. The Company's acquisition program has targeted
businesses which have provided the Company with complementary systems, equipment
and services and broadened its customer and geographic base. The Company has
sought companies which provide the potential for synergies with existing
businesses. With respect to the acquisitions completed prior to fiscal 1997, the
Company has begun to realize significant improvement in internal growth rates
due to the opportunities to cross-sell systems, equipment and services and as a
result of the increased financial, managerial and other resources provided by
the Company to its acquired businesses. The Company expects that it will
continue to benefit from such synergies as it more fully integrates the acquired
businesses into its operations.
 
     The acquisitions were accounted for under the purchase method of accounting
and are included in the results of operations for the period subsequent to the
effective date of acquisition. Due to the timing and magnitude of these
acquisitions, results of operations for the periods presented below are not
necessarily comparable or indicative of operating results for current or future
periods.
 
     The majority of the Company's systems and equipment are custom designed and
take a number of months to produce. Revenues from large contracts are recognized
using the percentage of completion method of accounting in the proportion that
costs bear to total estimated costs at completion. Revisions of estimated costs
or potential contract losses, if any, are recognized in the period in which they
are determined. Revenues from remaining systems and equipment sales are
recognized when shipped.
 
   
     The Company has in the past experienced quarterly fluctuations in operating
results due to the contractual nature of its business and, to a lesser extent,
weather conditions. As part of its strategic plan and due to the Pending
Acquisitions, the Company expects that in the future it may receive contracts
that are significantly larger than those received by the Company historically.
In addition, certain of such contracts will be subject to the customer's ability
to finance, or fund from government sources, the actual costs of completing the
project as well as receiving any necessary permits to commence the project.
Therefore, the Company expects that its future operating results could fluctuate
significantly, especially on a quarterly basis, due to the timing of the
awarding of such contracts, the ability to fund project costs, and the
recognition by the Company of revenues and profits therefrom. In addition, the
Company has historically operated with a moderate backlog. However, as a result
of its strategic plan and the Pending Acquisitions, the Company anticipates that
both the dollar volume and number of contracts in its backlog will increase
significantly. As of May 15, 1997, the Company's backlog was $30.0 million.
Therefore, quarterly sales and operating results may be affected by the volume
and timing of contracts received and performed within the quarter, which are
difficult to forecast. Any significant deferral or cancellation of a contract
could have a material adverse effect on the Company's operating results in any
particular quarter. Because of these factors, the Company believes that
period-to-period comparisons of its operating results are not necessarily
indicative of future performances.

     Net Sales
 
   
     Net sales for the six months ended March 31, 1997 were $24,727,000, an
increase of $16,484,000 from the comparable prior period. The increase was
primarily attributable to the contributions from Mass Transfer, which was
acquired on January 31, 1996, and from Aero-Mod, Waterlink Technologies and the
Nordic Group, which were acquired after March 31, 1996. In addition, internal
growth accounted for $2,484,000 of the increase, which represented an internal
growth rate of 30.1%, primarily due to the greater levels of financial resources
provided by the Company to businesses acquired in fiscal 1995 than the levels

     Gross profit for the six months ended March 31, 1997 was $9,927,000, an
increase of $6,505,000 from the comparable prior period. The increase was
primarily due to the aforementioned acquisitions. Gross margin was 40.1% for the
six months ended March 31, 1997 as compared to 41.5% for the comparable prior
period.
    
 
     Selling, General and Administrative Expenses
 
   
     Selling, general and administrative expenses for the six months ended March
31, 1997 were $7,478,000, an increase of $4,581,000 from the comparable prior
period. The increase was primarily due to the aforementioned acquisitions.
Selling, general and administrative expenses as a percentage of net sales was
30.2% for the six months ended March 31, 1997 as compared to 35.1% for the
comparable prior period. This decrease primarily reflected the spreading of
corporate overhead expense over a larger sales base.
    
 
     Amortization
 
   
     Amortization expense for the six months ended March 31, 1997 was $280,000,
an increase of $163,000 from the comparable prior period. The increase was
primarily due to the goodwill resulting from the aforementioned acquisitions.
    
 
     Interest Expense
 
   
     Interest expense for the six months ended March 31, 1997 was $612,000, an
increase of $258,000 from the comparable prior period. This increase was
primarily related to increased borrowings required to finance the aforementioned
acquisitions.

Fiscal Year Ended September 30, 1996 compared to Fiscal Year Ended September 30,
1995
 
     Net Sales
 
     Net sales for fiscal 1996 were $19,801,000, an increase of $17,117,000 from
the comparable prior period. Substantially all of the increase was attributable
to the timing of the acquisitions of Great Lakes in fiscal 1995 and, Mass
Transfer and Aero-Mod in fiscal 1996.
 
     Gross Profit
 
     Gross profit for fiscal 1996 was $8,568,000, an increase of $7,741,000 from
the comparable prior period. The increase was primarily due to the timing of the
aforementioned acquisitions. Gross margin was 43.3% for fiscal 1996 as compared
to 30.8% in fiscal 1995. Sanborn Technologies, which comprised the majority of
fiscal 1995 net sales, has historically experienced a lower gross margin than
the Company's other operating subsidiaries.
 
     Selling, General and Administrative Expenses
 
     Selling, general and administrative expenses for fiscal 1996 were
$7,029,000, an increase of $5,851,000 from the comparable prior period. The
increase was primarily due to the timing of the aforementioned acquisitions.
Selling, general and administrative expenses as a percentage of net sales was
35.5% for fiscal 1996 as compared to 43.9% for the comparable prior period in
fiscal 1995. This decrease as a percentage of sales primarily reflected the
spreading of corporate overhead expense over a larger sales base.
 
     Amortization
 
     Amortization expense for fiscal 1996 was $307,000, an increase of $292,000
from the comparable prior period. The increase was primarily due to the goodwill
resulting from the aforementioned acquisitions.
 
     Interest Expense
 
     Interest expense for fiscal 1996 was $877,000, an increase of $733,000 from
the comparable prior period. This increase primarily related to increased
borrowings to consummate the aforementioned acquisitions and fund working
capital expansion.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     Since its inception, the Company's primary sources of liquidity have been
(i) borrowings available under its Credit Facility (and prior credit
facilities), (ii) proceeds from the sale of the Company's preferred stock, and
(iii) issuance of Common Stock and seller financing incurred in connection with
the Company's completed acquisitions. Historically, the Company's primary uses
of capital have been the funding of its acquisition program and working capital
expansion. The Company does not currently anticipate making significant capital
investments in plant and equipment due to its focus on partnering with vendors
which manufacture most of the components used in the Company's systems and
equipment.
    
 
     For fiscal 1996, net cash used by operating activities was $14,000,
purchases of equipment totaled $423,000 and purchases of businesses, net of cash
acquired, totaled $5,557,000. These outlays were primarily financed by the sale
of shares of the Company's preferred stock in the aggregate amount of
$4,576,000, long-term borrowings, and excess cash balances.
 
   
     For the six months ended March 31, 1997, net cash used by operating
activities was $1,972,000, purchases of equipment totaled $439,000 and purchases
of businesses, net of cash acquired, totaled $8,750,000. These cash outlays,
financed primarily by long-term borrowings, reflect the Company's continued
acquisition program and expansion of existing operations.
    
 
     The net proceeds from the Offering will be used primarily to pay the cash
portion of the purchase prices for the Pending Acquisitions and for the
repayment of outstanding indebtedness. Such applications will enable the Company
to reduce its leverage and expand its product offerings which together are
anticipated to improve its financial flexibility and enhance the implementation
of its strategic plan.
 
                                       24
<PAGE>   28
 
     The Company intends to continue pursuing attractive acquisition
opportunities. The timing, size or success of any acquisition effort and the
associated potential capital commitments are unpredictable. The Company believes
that through the end of fiscal 1998, (i) future cash flow from operations, (ii)
borrowings under its New Credit Facility (as hereafter defined) and (iii)
issuances of Common Stock and seller financing incurred in connection with
future acquisitions will be sufficient to fund its working capital needs,
additional acquisitions and additional contingent consideration related to
acquisitions.
 
Acquisitions
 
   
     As part of its strategic plan, the Company has implemented an acquisition
program, which has significantly impacted liquidity and capital resources. Upon
consummation of the Offering, the Company will have made eight acquisitions
consisting of fifteen operating companies for an aggregate consideration of
$57,035,000, comprised of $41,210,000 of cash, $6,711,000 of Common Stock, and
$9,114,000 of seller financing, including convertible debt.
    
 
   
     The Company may be required to make additional purchase consideration
payments of up to $4,465,000, contingent upon the achievement of certain
operating results through fiscal 2000. The payments that may be required in
fiscal 1997, 1998, 1999 and 2000 are $800,000, $2,200,000, $733,000 and
$732,000, respectively. In connection with two of the Company's acquisitions,
the Company also may be required to make other additional purchase consideration
payments in the form of cash and Common Stock, in an amount equal to a fixed
percentage of the excess of certain specified annual earnings targets through
fiscal 2000. Since such additional purchase consideration payments, if any, are
based on a fixed percentage of such excess amount, there is no maximum amount
for such payments. Any such additional purchase consideration payments will be
treated as additional goodwill for accounting purposes.
    
 
Credit Availability
 
     On February 19, 1997, the Company entered into the Credit Facility with
Bank of America Illinois. The Credit Facility provides the Company with a
revolving line of credit of up to $8,000,000 and a term loan of $11,000,000. The
revolving line of credit has a sublimit of $6,000,000 for letters of credit and
can be used for working capital and other general corporate purposes, including
the financing of acquisitions. The term loan was used to acquire the Nordic
Group and to refinance certain indebtedness in connection with the acquisition.
Loans under the revolving line of credit and the term loan bear interest at a
designated variable base rate plus spreads ranging from 0 to 50 basis points and
25 to 75 basis points, respectively, depending on the ratio of total
consolidated indebtedness to the Company's earnings before interest, taxes,
depreciation and amortization. At the Company's option, the loans under the
revolving line of credit and the term loan may bear interest based on a
designated London interbank offering rate plus spreads ranging from 175 to 225
basis points and 200 to 250 basis points, respectively, based on the same ratio.
The revolving line of credit terminates on February 18, 2000, and the term loan
matures on February 19, 2002. The term loan has mandatory quarterly repayments
commencing June 30, 1997 in amounts ranging from $400,000 to $750,000 per
repayment. The Credit Facility prohibits or restricts the Company from many
actions, including paying dividends and incurring or assuming other indebtedness
or liens.
 
   
     The Company's obligations under the revolving line of credit and the term
loan are secured by liens on substantially all of the Company's assets,
including equipment, inventory, accounts receivable and general intangibles and
a pledge of most of the stock of the Company's subsidiaries. As additional
security, Brantley Venture Partners III, L.P., a principal shareholder of the
Company, has executed a guaranty of $2,000,000 of indebtedness under the
revolving line of credit and term loan. See "Certain Transactions -- 1997 Notes,
1997 Warrants and Stockholder Guarantee."
    
 
     As part of the Credit Facility, two of the foreign subsidiaries of the
Company have separate facilities of $2,200,000 and $3,800,000, respectively, for
borrowings in local currencies. Each separate facility is guaranteed by the
Company. Both of these facilities mature in February 2000, with outstanding
amounts bearing interest based on a designated London interbank offering rate
plus a spread of 250 basis points.
 
                                       25
<PAGE>   29
 
   
     As of May 15, 1997, there was $5,960,000 outstanding under the revolving
line of credit, $11,000,000 outstanding under the term loan and $5,377,000
outstanding under the two separate foreign facilities.
    
 
   
     As additional consideration for the Credit Facility, the Company has
granted the Bank, pursuant to a certain warrant agreement dated February 19,
1997 (the "Bank Warrant Agreement"), a warrant, expiring in 2002, to purchase
225,000 shares of Common Stock at a purchase price of $4.50 per share.
    
 
   
     Upon consummation of the Offering, the Company anticipates that it will
terminate its Credit Facility and enter into a new $50,000,000 three year,
multi-currency, secured, revolving credit facility with Bank of America Illinois
(the "New Credit Facility") to fund operating activities of the Company as well
as future acquisitions. Loans under the New Credit Facility will bear interest
at a designated variable base rate plus spreads ranging from 0 to 25 basis
points depending on the ratio of total consolidated indebtedness to the
Company's earnings before interest, taxes, depreciation and amortization. At the
Company's option, the New Credit Facility may bear interest on a designated
London interbank offering rate plus spreads ranging from 100 to 200 basis
points, based on the same ratio.
    
 
     In March 1997, the Company entered into a note purchase agreement (the
"Note Purchase Agreement") pursuant to which the Company may issue, and several
purchasers have committed to purchase, five year subordinated notes in the
principal amount of up to $10,000,000 (the "1997 Notes"). As of the date of this
Prospectus, none of the 1997 Notes are outstanding. Each 1997 Note would bear
interest at a rate of 12% per annum for the first twelve months after its
issuance date and at a rate of 14% per annum thereafter. In consideration of
entering into the Note Purchase Agreement, parties agreeing to be purchasers of
the 1997 Notes received 125,000 warrants to purchase shares of Common Stock. See
"Description of Capital Stock -- 1997 Warrants." The 1997 Notes, if any are then
outstanding, will become payable at the completion of the Offering. The Note
Purchase Agreement will terminate upon completion of the Offering.
 
Accounting Charges in Connection with the Offering
 
   
     A special charge to operations of approximately $2.6 million ($0.13 per
share, after tax), assuming an initial public offering price of $11.00 per
share, will be incurred in the quarter in which the Offering is completed. Such
charge results primarily from the issuance upon completion of the Offering by
the Company of a ten year option to purchase 100,000 shares of Common Stock at a
price of $.10 per share to an officer of the Company pursuant to the terms of an
employment agreement. Of this amount, approximately $1.1 million is non-cash,
and approximately $1.5 million represents cash payments relating principally to
the reimbursement of income taxes resulting from this stock option issuance.
    
 
   
     An extraordinary non-cash charge of $355,000, net of tax benefit of
$267,000 ($0.02 per share) will be incurred by the Company in the quarter in
which the Offering is completed. Such charge relates to the write-off of
unamortized debt issuance costs and discounts associated with certain
indebtedness to be repaid with net proceeds of the Offering.
    
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
     In October 1995, the Financial Accounting Standards Board (the "FASB")
issued Statement of Financial Accounting Standards ("SFAS") No. 123, Accounting
for Stock-Based Compensation, which provides an alternative to APB Opinion No.
25, Accounting for Stock Issued to Employees, in accounting for stock-based
compensation issued to employees. The Company intends to account for stock
options in accordance with APB Opinion No. 25. The disclosure requirements of
SFAS No. 123, which are required if an entity elects to continue to use the
accounting method in APB Opinion No. 25, will be adopted as required for the
Company's fiscal 1997 financial statements.
 
     In February 1997, the FASB issued SFAS No. 128, Earnings Per Share. SFAS
No. 128 replaces the presentation of primary earnings per share ("EPS") under
Accounting Principles Board Opinion No. 15 and related Interpretations, with the
presentation of basic EPS (which primarily gives effect only to common shares
actually outstanding) and requires dual presentation of basic and diluted EPS on
the face of the income statement for all entities with complex capital
structures. The Company is required to adopt SFAS No. 128
 
                                       26

during the first quarter of fiscal 1998. The Company has not completed its
evaluation of the potential impact of this new standard on EPS in future
periods.
    
 
   
            THE WATER PURIFICATION AND WASTEWATER TREATMENT INDUSTRY
    
 
GENERAL
 
     Demand for water purification and wastewater treatment has continued to
grow world-wide due to economic expansion, scarcity of usable water, concern
about water quality and regulatory requirements. Industrial companies require
treated water for most manufactured products, whether as an ingredient in
finished products or as part of the manufacturing process. Municipalities,
responsible for providing potable water, employ water treatment technology to
purify the water supply. Additionally, industrial companies and municipalities
are required by law to treat outgoing wastewater, primarily in the United
States, Canada and western Europe and, to a lesser extent, in the rest of the
world.
 
     The global water treatment market was estimated at $300 billion in 1995 and
was divided as follows: municipal wastewater treatment, 36%; drinking water,
30%; industrial process water, 20%; and industrial wastewater treatment, 14%. By
the year 2000, when expenditures for water purification and wastewater treatment
are expected to reach $500 billion, the municipal water market is forecasted to
total $300 billion, and the industrial water market to total $200 billion.
 
     The water purification and wastewater treatment industry is highly
fragmented, with thousands of companies involved in various capacities. Diverse
customer needs have created a demand for companies that are able to provide a
broad range of technologies, products and cost effective solutions. Most water
treatment companies provide only a limited number of products or services and
are unable to provide integrated solutions to their customers. These limitations
have helped propel industry consolidation and have created acquisition and
expansion opportunities. The Company believes an accelerated acquisition and
consolidation phase is likely in the water purification and wastewater treatment
industry in foreseeable future.
 
INDUSTRIAL USERS
 
     Most industries, including the pharmaceutical, electronic and
microelectronic, pulp and paper, chemical, petrochemical, food, beverage,
automotive and other heavy manufacturing industries, are dependent on purified
water for their manufacturing processes. The use of untreated water in
manufacturing processes can result in unusable products, inconsistent product
quality, and in equipment degradation, leading to costly maintenance or
replacement. Increasingly, industrial companies are outsourcing their pure water
needs. A number of elements have driven this shift, including a current trend
among companies to focus on core competencies, the desire to reduce operating
costs, and the growing use of off-balance sheet financing.
 
     In the United States, Canada, and western Europe, industrial users are
often required to treat their wastewater as a result of government regulations
and public sensitivity to industrial pollution. Outside these regions, many
multinational corporations are applying throughout their global operations
standards similar to those in effect in the United States, Canada and western
Europe even though local regulations do not yet require adherence to those
standards. However, regulations are becoming more important in these regions.
For example, the North American Free Trade Agreement has resulted in a more
rigorous regulatory environment in Mexico and water purification and wastewater
treatment laws in Chile have become more stringent. Additionally, due to higher
water prices and wastewater discharge fees, industrial manufacturers have also
become aware of the cost-effectiveness of recycling their wastewater. Waste
minimization and water reuse are increasingly significant incentives for growth
in the wastewater treatment industry because the economic benefits outweigh the
associated treatment costs. Reuse can lower costs by reducing the need for
costly water and water purification, waste treatment, and waste disposal. As a
result of these factors, industrial companies increasingly require complex
systems and equipment to treat and recycle process water and wastewater. It is
estimated that from 1995 to 2000, water purification and wastewater treatment
expenditures by industrial users will increase at a compound annual growth rate
of approximately 14%.
 
                                       27
<PAGE>   31
 
MUNICIPAL USERS
 
     In many countries throughout the world, particularly in the United States,
Canada and western Europe, governmental regulation and enforcement have required
strict standards for potable water and the discharge of pollutants in wastewater
for many years. These municipalities have spent billions of dollars building
water purification and wastewater treatment facilities, which historically they
have managed. However, many of these municipalities are facing increasing
budgeting constraints and thus are seeking alternatives to maintaining and
upgrading their aging facilities. As a result, many such potential customers are
seeking improved technologies and equipment, and various outsourcing
opportunities such as contract operations and privatization. Privatization
involves the transfer of ownership and operation of water purification and
wastewater treatment facilities to companies capable of providing such services
on a long-term basis.
 
     As a result of economic and infrastructure growth, as well as public
sensitivity to water quality, in other areas of the world, including Latin
America, eastern Europe and the Asia-Pacific region, the demand for water
purification and wastewater treatment is increasing. In these areas,
municipalities seek to utilize the most cost-effective and manageable
technologies and are often more receptive to new solutions than municipalities
in more regulated regions of the world. In addition, these municipalities often
seek to have a third party manage these new facilities.

                                    BUSINESS
 
GENERAL
 
   
     The Company is an international provider of integrated water purification
and wastewater treatment solutions, principally to industrial and municipal
customers. The Company believes its expertise is in the analysis of a customer's
water purification and wastewater treatment requirements and the customized
application of the Company's systems, equipment and services to provide cost
effective solutions. Since its formation in December 1994, the Company has grown
significantly by completing six acquisitions consisting of thirteen operating
companies. In addition, the Company will complete the Pending Acquisitions
simultaneously with the closing of the Offering. As a result of its acquisition
program and internal development, the Company has increased its ability to
provide integrated water purification and wastewater treatment solutions and has
expanded its geographic presence.
    
 
     The Company has developed a strategic plan to:
 
        -  Provide a full range of systems, equipment and
          services, whether independently or as part of a
          fully engineered water purification or wastewater
          treatment solution
 
        -  Pursue growth through acquisitions that:
 
          --  increase its geographic diversity
 
          --  add complementary technologies, products and
             services
 
          --  broaden its customer base and industries served
 
          --  provide strategic, synergistic and corporate
             cultural fit
 
        -  Integrate its operations and marketing strategies
          in order to maximize internal growth and increase
          profitability
 
        -  Strengthen market share for its design/build
          operations outside the United States
 
   
     As a result of the implementation of its strategic plan, the Company's pro
forma net sales for fiscal 1996 totaled $72.7 million, primarily due to its
acquisition program. In addition, the Company has begun to realize significant
improvement in internal growth rates due to the opportunities to cross-sell
systems, equipment and services and as a result of the increased financial,
managerial and other resources provided by the Company to its acquired
businesses. Pro forma net sales of the businesses acquired by the Company prior
to fiscal 1997 grew 26.3% for the six months ended March 31, 1997 compared to
the comparable period in the prior year. The Company's backlog on a pro forma
basis, consisting of written purchase orders received by the Company, was $30.0
million at May 15, 1997.
    
 
ACQUISITION STRATEGY
 
     In order to achieve its objective of becoming a leading international
provider of integrated water purification and wastewater treatment solutions,
the Company has pursued an aggressive acquisition-based growth program. In
connection with this program, the Company targets acquisitions that will expand
the Company's market share, broaden its customer and geographic base, provide
the Company with new products, technologies and services (including those which
generate recurring revenues), and enhance the Company's design/build
capabilities. The Company seeks well-managed, established companies that provide
a strategic fit, synergies with existing businesses and the potential for
accelerated revenue and earnings growth. Assuming that a potential acquisition
is complementary to, and synergistic with, the operation of the Company's
existing subsidiaries, the candidate company is evaluated for cultural fit,
which the Company considers to be critically important. The Company believes
that its future success depends substantially upon collaboration and teamwork
among its operating companies and therefore upon common operating philosophies.
 
                                       29
<PAGE>   33
 
     The Company believes that it is an attractive partner to potential
acquirees because the Company can facilitate their continued growth through
enhanced availability of working capital, surety credit, and borrowing capacity,
as well as through introduction to new customers and markets. The Company also
offers smaller acquisition candidates the ability to remain competitive by
becoming part of a larger, more diversified organization. As customers
frequently seek integrated water treatment solutions, companies with one or a
few product lines are increasingly excluded from projects because they do not
have the capability of meeting customers' requirements either from a product or
financial standpoint. The Company offers acquisition candidates access to a
developed international distribution system and significant management
experience. Additionally, the Company's operating subsidiaries have
cross-selling opportunities which enable them to be considerably more
competitive, thereby increasing sales potential significantly. Finally, and of
utmost importance to some candidates, it is the Company's philosophy generally
to maintain an acquired company's culture and retain its management through
appropriate incentives. The Company's decentralized operating strategy offers an
environment in which initiative and entrepreneurial spirit can thrive.
 
     The Company believes that there is a substantial number of attractive
acquisition candidates in the United States and abroad due to the highly
fragmented nature of the overall industry. These candidates include water
purification equipment and wastewater equipment manufacturers, design/build
companies, point-of-use/point-of-entry equipment providers, contract operations
companies, and regional service companies.
 
   
     As consideration for future acquisitions the Company intends to continue to
use various combinations of its Common Stock, cash and notes. The consideration
for each future acquisition will vary on a case-by-case basis depending on the
financial interests of the Company and the historic operating results and future
prospects of the business to be acquired. The Company will finance future
acquisitions from a portion of the proceeds of the Offering, through funds
provided by operations and by the New Credit Facility and from the proceeds of
future equity and debt financing. The Company intends to register 5,000,000
shares of Common Stock under the Securities Act during the fourth quarter of
fiscal 1997 for use in connection with future acquisitions.
    
 
SYSTEMS, EQUIPMENT AND SERVICES
 
     The Company provides integrated water purification and wastewater treatment
solutions, principally to its industrial customers for treatment of process
water and wastewater and to its municipal customers for treatment of drinking
water and wastewater . To this end, the Company provides a broad range of
systems and equipment as well as design/build and operating capabilities.
 
     Systems and Equipment.  The Company designs and engineers solutions for the
water purification and wastewater treatment industry. The Company believes its
expertise is in the analysis of a customer's water purification and wastewater
treatment requirements and the application of the Company's systems, equipment
and services to provide cost effective solutions. The Company's equipment can be
provided to a customer either as a separate component or as part of a
customized, fully engineered water purification or wastewater treatment system
or subsystem. The Company generally does not make significant capital
investments in plant and equipment, focusing instead on partnering with vendors
which manufacture the components used in the Company's systems and equipment.
The Company completes the final assembly of its systems and tests its systems
prior to final delivery to the customer in order to maintain quality control.
The Company manufactures equipment when its manufacturing process is determined
to add a significant value to the final product.
 
     Design/Build Services.  The Company's design/build services include
prescribing water purification and wastewater treatment solutions, designing and
engineering necessary facilities, arranging for construction when required and
installing necessary equipment. The Company's strategy is to expand its presence
in the design/build segment of the water purification and wastewater treatment
industry, particularly in the small and medium sized municipal markets outside
the United States. During the past five years, the Company has completed more
than 50 design/build projects.
 
                                       30
<PAGE>   34
 
     The Company anticipates that it will expand its activities in this area due
to the trend toward outsourcing in the industry. The Company uses many of its
own products in its design/build operations as well as products manufactured by
others where appropriate.
 
     Contract Operations.  The Company operates water purification and
wastewater treatment facilities for municipal customers under contract for
varying time periods. The Company currently operates three small municipal
wastewater treatment facilities in the United States and one in Chile. The
Company's strategy is to leverage its design/build services to offer its
contract operations capability as part of a total solution. The Company is
becoming more involved in the operation and remote monitoring of water
purification and wastewater treatment facilities for both its industrial and
municipal customers.
 
     Replacement Parts, Repairs and Consumables.  The Company manufactures and
sells replacement parts and consumables, such as membranes, ion exchange resin
and filter cartridges, manufactured both by the Company and other suppliers.
This equipment is required to support water treatment systems. In addition, the
Company performs maintenance and repair services on equipment manufactured by
both the Company and others.

OPERATING STRATEGY
 
     The Company has adopted a decentralized approach to the operational
management of its subsidiaries. While functions such as financial reporting,
treasury, communications and risk management are centralized in the Company's
corporate headquarters, local management is primarily responsible for the
day-to-day
 
                                       32
<PAGE>   36
 
operation of its business. The Company also provides its subsidiaries with
financial resources, management expertise, customer and market access which
would be unavailable to each subsidiary individually. With respect to
acquisitions already completed, the Company has begun to realize significant
improvement in internal growth rates due to the availability of capital and
bonding capacity, and the opportunities to "cross-sell" products. As customers
increasingly seek integrated solutions, the ability of each of the Company's
subsidiaries to offer complementary equipment and services of other subsidiaries
increases the competitiveness of each company. For example, subsidiaries selling
wastewater treatment systems now have the ability to offer both aeration and
mixing systems and subsidiaries selling water treatment systems can now offer
wastewater treatment systems for the same projects. Additionally, the Company's
design/build capabilities allow it to design systems that utilize a broad array
of the Company's products and provide opportunities for its contract operation
services. The Company also experiences cross-selling opportunities from a
geographic and customer standpoint. For example, the Company believes that it
should benefit from the recent acquisition of the Nordic Group both from the
Nordic Group's ability to introduce the Company's existing systems, equipment
and services into the European market and from the Company's ability to
introduce the Nordic Group's systems, equipment and services into the Company's
existing markets.
 
     A representative from each subsidiary, along with the Company's executive
officers and other key employees, form the Company's operating committee, which
meets on a frequent basis to facilitate the interchange of information and
enhance cross-selling opportunities. As the Company's capabilities have grown,
acquired subsidiaries within the Company have enjoyed growth opportunities far
beyond those that exist for stand-alone companies specialized in only one
segment of the industry.
 
SALES AND DISTRIBUTION
 
     The Company sells its systems, equipment and services primarily through
approximately 50 direct sales personnel and approximately 250 independent sales
organizations. To a lesser extent, the Company sells through water treatment
distributors which take title to equipment for resale to the end-user. The
Company seeks to have a single sales organization within a particular market in
order to foster a close relationship with its sales representatives and present
a cohesive image to the marketplace. The independent sales representatives
typically will identify sales opportunities, and then work together as a team
with the Company's direct sales force, which has greater technical and product
knowledge, to complete the sale and service the customer. The Company's direct
sales force generally plays a more primary role in sales of the Company's
design/build solutions. The Company also sells through licensees, principally in
the Asia-Pacific region as well as in Europe.
 
CUSTOMERS
 
     The Company markets its products and services to two primary categories of
customers; industrial users which require water for their manufacturing
processes and treat their wastewater, and municipal customers which produce
drinking water and treat wastewater. The Company has a diverse customer base,
with no customer representing 10% or more of the Company's fiscal 1996 pro forma
net sales.
 
     The Company's industrial customers include many "Fortune 500" companies and
their counterparts outside of the United States. Industries served include the
pharmaceutical, electronic and microelectronic, pulp and paper, chemical,
petrochemical, food, beverage, automotive and other heavy manufacturing
industries. In fiscal 1996 approximately 60% of the Company's pro forma net
sales were derived from industrial sales.
 
     The municipal market is highly competitive. Municipal markets in the United
States, Canada and western Europe are more regulatory driven than municipal
markets in other regions. The Company utilizes specialized distribution channels
to service the municipal market and is skilled at participating in the municipal
bidding process. The Company focuses its efforts on smaller municipal projects
which the Company believes its product lines are best suited to serve. The
Company believes that the municipal business is important to its overall success
by virtue of its large market size. In fiscal 1996 approximately 40% of the
Company's pro forma net sales were derived from municipal sales.
 
                                       33
<PAGE>   37
 
BACKLOG
 
   
     The Company had a backlog, consisting of written purchase orders received
by the Company, on a pro forma basis, of $30.0 million as of May 15, 1997. The
Company expects that nearly all of the backlog at the beginning of a fiscal year
will be filled during that year. Backlog may vary from quarter to quarter as a
result of large projects being booked during any quarter and varying project
delivery schedules. In addition, the orders have varying delivery schedules and
the Company's backlog as of any particular date may not be representative of
actual net sales for any succeeding period.
    
 
PROCESS AND PRODUCT WARRANTY AND PERFORMANCE GUARANTEES
 
   
     Consistent with market practices, the Company generally offers a warranty
on finished products for one year or in some cases 18 months from sale and 12
months from installation. The costs associated with warranty expense have not
been material. In connection with providing certain products and design/build
services to its customers, the Company is sometimes required to guarantee that
the products or services will attain specified levels of quality or performance,
based on a defined set of parameters. Should a product fail to perform according
to a warranty, or should a project fail to attain the guaranteed level of
quality, and should the Company be unable to effect a satisfactory replacement
or cure within the prescribed period of time, the Company could incur financial
penalties in the form of liquidated damages or could be required to remove and
replace the equipment or repeat the service in order to meet the specifications.
To date, the Company has not incurred any material payment or other obligations
pursuant to such performance guarantees.
    
 
RAW MATERIAL AND SUPPLIES
 
     The raw materials and components used in the Company's products are
commonly available commodities such as stainless steel, carbon steel, plastic,
tubing, wiring, electrical components, pumps, valves, compressors, pressure
vessels, oleophilic media, reverse osmosis membranes and sand. The Company's
systems are fabricated from these materials and assembled together with products
bought from other companies to form an integrated system. The Company is not
dependent upon any single supplier, and if any supplier were to become unable to
perform, the Company believes a substitute source could readily be found. The
Company has generally been able to pass on price increases for raw materials and
components to its customers. The Company is not a party to any material
long-term fixed price supply contracts.
 
GOVERNMENT REGULATION
 
     Federal, state, local and foreign environmental laws and regulations
necessitate substantial expenditures and compliance with water quality standards
by generators of wastewater and wastewater by-products and impose liabilities on
such entities for noncompliance. Environmental laws and regulations and their
enforcement are, and will continue to be, a significant factor affecting the
marketability of the solutions, systems and equipment provided by the Company.
 
     In the United States, the Environmental Protection Agency has promulgated
regulations under the Clean Water Act that address the issues of treatment of
wastewater and the subsequent disposition of end products and by-products
generated in the treatment process. These regulations establish use and disposal
standards applicable to approximately 60,000 public and privately owned
wastewater treatment plants in the United States, including approximately 26,000
public owned treatment works. These regulations also establish specific effluent
limitations for the discharge of pollutants in wastewater.
 
     The treatment of drinking water in the United States is also governed by
the Safe Drinking Water Act (the "SDWA"). The 1996 drinking water amendments to
the SDWA emphasize risk-based standards for contaminants in drinking water,
afford small water supply systems operational flexibility and provide assistance
to water system infrastructures through a multi-billion-dollar Drinking Water
State Revolving Fund (the "DWSRF"). The DWSRF program assists public water
systems with the financing of the costs of drinking water infrastructure that is
necessary to achieve or maintain compliance with the SDWA requirements and to
protect public health. The DWSRF, patterned after the State Revolving Fund
contained in the Clean Water
 
                                       34
<PAGE>   38
 
Act, provides funding to the states to establish a renewable source of financing
for drinking water infrastructure projects. The DWSRF program is designed to
ensure that the drinking water supplies in the United States remain safe and
affordable, and that systems that receive funding will be properly operated and
maintained. Regulations under the SDWA also establish maximum contaminant levels
(MCLs) for a wide variety of chemicals that may be present in drinking water and
require treatment to meet applicable standards.
 
     Many of the countries in which the Company operates or in which its
customers are located, including Canada and countries in western Europe, Latin
America, and the Asia-Pacific region, have adopted requirements that govern
water quality, wastewater treatment, and wastewater by-products and the
solutions, systems and equipment provided by the Company. These requirements and
their enforcement vary by country, but in general establish water quality use
and disposal standards, set wastewater effluent discharge limits, and prescribe
standards for the protection of human health and safety and the environment. In
each such country, the Company monitors the status and impact of local
environmental regulation and enforcement as it relates to the marketability of
the solutions, systems and equipment provided by the Company.
 
     Any changes in applicable environmental requirements or their enforcement
may affect the operations of the Company by imposing additional regulatory
compliance costs on the Company's customers, requiring the modification of
and/or affecting the market for the Company's solutions, systems and equipment.
To the extent that demand for the Company's solutions, systems and equipment is
created by the need to comply with such enhanced standards or their enforcement,
any modification of the standards or their enforcement may reduce demand,
thereby adversely affecting the Company's business prospects. Conversely,
changes in applicable environmental requirements imposing additional regulatory
compliance requirements or causing stricter enforcement of these laws or
regulations could increase the demand for the Company's systems, equipment and
services.
 
     The water purification and wastewater treatment facilities at which the
Company's solutions, systems and equipment may be used are required to have
permits, registrations and approvals from governmental authorities in the United
States as well as foreign countries. Any of the permits, registrations or
approvals noted above, or applications therefor, may be subject to denial,
revocation or modification under various circumstances. In addition, if new
environmental laws or regulations are enacted or existing laws or regulations
are amended or are enforced differently, the Company's customers may be required
to obtain additional operating permits, registrations or approvals. The process
of obtaining a required permit, registration or approval can be lengthy and
expensive and the issuance of such permit or the obtaining of such approval may
be subject to public opposition. There can be no assurances that the Company
and/or its customers will be able to meet applicable regulatory requirements or
will be successful in obtaining required permits and approvals.
 
COMPETITION
 
     Despite an accelerating trend toward consolidation, the water purification
and wastewater treatment industry remains fragmented and highly competitive due
to the large number of competitors within each product area. The Company has a
significant number of competitors, including a number of integrated suppliers
and equipment manufacturers, some of which are larger and have greater resources
than the Company. The Company believes that success in this market is based on
the ability to offer appropriate technology, influence specifications, have
strong distribution, maintain respect within the consulting and engineering
community, finance and bond projects awarded, provide timely delivery, and
maintain a reputation for service and parts support after the sale.
Additionally, in the municipal arena, the ability to meet bid specifications and
pricing are often primary considerations. The Company believes that its
technologies and cost structures as well as its strong local presence in
international markets enable it to compete effectively against these companies.
 
     The Company's primary competitors include United States Filter Corporation,
Parkson Corporation, Alpha Laval and Humbolt KHD. See "Risk
Factors -- Competition."

<PAGE>   39
 
PATENTS, TRADEMARKS AND LICENSES
 
     The Company currently owns a number of United States and foreign patents,
and registrations for United States service marks and trademarks. While each is
of value, the Company does not consider any of them to be material to its
business.
 
EMPLOYEES
 
   
     At May 15, 1997, the Company and its subsidiaries had approximately 310
employees at its various locations. None of the Company's employees in the
United States are covered under collective bargaining agreements. The Company's
hourly employees in Europe are covered by collective bargaining agreements.
Management believes that the Company's relationship with its employees is good.
    
 
LITIGATION
 
     The Company is, from time to time, a party to litigation arising in the
normal course of its business, most of which involves claims for personal injury
or property damage incurred in connection with its operations. The Company is
not a party to any material litigation and does not know of any threatened claim
that may result in material litigation.
 
PROPERTIES
 
   
     The Company leases its corporate offices, consisting of 4,975 square feet
located in Canton, Ohio pursuant to a lease agreement dated July 9, 1996. In
addition, its subsidiaries lease facilities for office space and manufacturing
in Medway, Massachusetts; Addison, Illinois; Manhattan, Kansas; West Palm Beach,
Florida; Sarasota, Florida; Clearwater, Florida; Nynashamn, Sweden; Kungsbacka,
Sweden; Neuss-Grimlinghausen, Germany; Holstebro, Denmark; and Grand Rapids,
Michigan, and own facilities for office space and manufacturing in Fall River,
Massachusetts; Winnipeg, Manitoba, Canada; and Fjaras, Sweden. The expiration
dates for these leases range from March 31, 1998 to December 31, 2003.
    
 
     The Company believes that each of its facilities is in good condition and
will continue to remain suitable for its current purpose. The Company may add
improvements to the properties listed above. The Company anticipates using its
properties for purposes consistent with their present use. In the event any of
the facilities becomes unavailable upon termination of the existing lease, the
Company believes it would be able to find a suitable alternative facility
without resulting in any significant adverse impact to the Company or its
operations. In the opinion of management of the Company, the properties
described above are adequately covered by insurance.

Plan, which will entitle him to earn, in each year during the term of his
employment agreement, commencing with fiscal 1998, an amount ranging from 0% to
150% of his base salary, subject to achievement of certain performance goals to
be established by the Board from the Company's annual operating plan. In
addition, Mr. Ross will continue to be provided with certain benefits and
perquisites currently provided to him. In the event that Mr. Ross' employment is
terminated without cause (as defined in the employment agreement) or in the
event he terminates his employment for good reason (as defined in the employment
agreement), Mr. Ross will be entitled to receive (in a lump sum if such
termination occurs within one year after a change of control (as defined in the
employment agreement) of the Company) an amount equal to the present value of
the product of (i) the sum of (x) the base salary in effect on the date of
termination and (y) the annual bonus compensation paid to Mr. Ross with respect
to the fiscal year in which his employment is terminated, provided that such
bonus is calculable as of such date, and if not so calculable, then the bonus,
if any, paid to him with respect to the fiscal year immediately preceding the
year in which his employment is terminated (which for fiscal 1996 and 1997 shall
be deemed to be $240,000) and (ii) two; provided, however, that if any portion
of such compensation would constitute an "excess parachute payment" under
Section 280G of the Code, the Company will pay to Mr. Ross an additional amount
to offset any taxes payable with respect to the excess parachute payment and the
additional payment. The employment agreement also contains provisions which
restrict Mr. Ross from competing with the Company during the term of the
agreement and for 24 months following termination thereof. Additionally,
pursuant to his employment agreement, under the terms of the Stock Option Plan,
Mr. Ross was granted a non-qualified option to purchase 300,000 shares of Common
Stock at $12 per share, which option price will be adjusted to the initial
offering price of the Common Stock sold in the Offering. This option shall be
exercisable in four equal annual installments, commencing upon the first
anniversary of the date of grant subject to acceleration in certain
circumstances.

COMPENSATION OF DIRECTORS
 
     Members of the Board who are employees of the Company do not receive any
additional compensation for service on the Board or any committees of the Board.
Each member of the Board who is not an employee of the Company receives, for
each year of service on the Board, a non-qualified stock option granted under
the Stock Option Plan (as defined below) to purchase 3,000 shares of Common
Stock, at a price equal to the fair market value of the Common Stock on the date
of grant. Each option vests according to a schedule determined by the Board of
Directors, with the initial option vesting in two equal annual installments. The
options become fully vested and immediately exercisable in the event of an
underwritten public offering of Common Stock (as will occur by completion of the
Offering). In addition, each member of the Board who is not an employee of the
Company is granted at the time he becomes a member of the Board the right to
acquire at any time prior to an underwritten public offering up to 25,000 shares
of Common Stock, at a price equal to the then current fair market value.
 
     Members of the Board who are not employees of the Company will receive an
annual retainer of $10,000, payable in equal quarterly installments. All
directors will be reimbursed for out of pocket expenses incurred in attending
meetings of the Board or committees and for other expenses incurred in their
capacity as directors.
 
     In June 1996, Robert P. Pinkas, a director of the Company, was granted

(1) There have been no stock appreciation rights ("SARs") granted by the Company
     to date.
 
(2) The potential realizable values represent future opportunity and have not
     been reduced to present value in 1996 dollars. The dollar amounts included
     in these columns are the result of calculations at assumed rates set by the
     Securities Exchange Commission (the "SEC") for illustration purposes. These
     rates are not intended to be a forecast of the Common Stock price and are
     not necessarily indicative of the values that may be realized by the Named
     Executive Officers. The potential realizable values are based on
     arbitrarily assumed annualized rates of stock price appreciation of 5% and
     10% over the full ten-year term of the options. For example, in order for
     the individuals named above who received options with an exercise price of
     $4.00 and $4.40 per share, respectively, for Common Stock to realize the
     potential values set forth in the 5% and 10% columns in the table above,
     the price per share of Common Stock would have to be approximately $6.52
     and $10.37, respectively.

BENEFIT PLANS
 
   
The Company's Omnibus Incentive Plan
    
 
   
     General Information.  The Company's Omnibus Incentive Plan (the "Omnibus
Plan") provides for compensatory equity based awards (each an "Award"). There
are reserved for issuance pursuant to, or by reason of, stock awards and
stock-based awards an aggregate number of shares of Common Stock equal to the
lesser of (x) the greater of (i) 1,750,000 shares or (ii) 12.5% of the number of
shares of Common Stock outstanding, from time to time, (calculated on a fully
diluted basis (including the maximum number of shares that may be issued, or
subject to awards, under the Omnibus Plan and the Stock Option Plan (as defined
below) (collectively, the "Employee Stock Plans"))); in either case (i) or (ii)
above less the number of shares that are issued under the Employee Stock Plans
after the effective date of the Omnibus Plan or are subject to outstanding
awards under the Employee Stock Plans plus the number of any shares surrendered
to the Company in payment of the exercise price of options issued under either
of the Employee Stock Plans or (y) 5,000,000 shares of Common Stock. The
foregoing amount is referred to herein as the "Employee Stock Plan Share
Amount." Awards may be granted for no consideration and consist of stock
options, stock awards, SARs, dividend equivalents, other stock based awards
(such as phantom stock) and performance awards consisting of any combination of
the foregoing. The Omnibus Plan is designed to provide an incentive to the
officers and certain other key employees of the Company by making available to
them an opportunity to acquire a proprietary interest or to increase their
proprietary interest in the Company. Any Award issued under the Omnibus Plan
which is forfeited, expires or terminates prior to vesting or exercise will
again be available for Award under the Omnibus Plan. No participant may receive
stock or stock-based awards to acquire more than 500,000 shares in any one year.
    
 
     The Compensation Committee administers the Omnibus Plan and has the full
power and authority, subject to the provisions of the Omnibus Plan, to designate
participants, grant Awards and determine the terms of all Awards. Members of the
Compensation Committee are not eligible to receive Awards under the Omnibus
Plan.
 
   
     The Omnibus Plan was approved by the Company's Board and shareholders in
May 1997, and will terminate on the tenth anniversary of the date approved by
the Board.
    
 
     Stock Awards.  The Compensation Committee has the right to grant Awards of
shares of Common Stock which are subject to such restrictions (including
restrictions on transferability and limitations on the right to vote or receive
dividends with respect to the restricted shares) and such terms regarding the
lapse of restrictions as the Compensation Committee deems appropriate.
Generally, upon termination of employment for any reason during the restriction
period, restricted shares will be forfeited to the Company.
 
   
     SARs.  An Award may consist of SARs. Upon exercising an SAR, the holder
will be paid by the Company the difference between the fair market value of the
Common Stock on the date of exercise and the fair market value of the Common
Stock on the date of the grant of the SAR, less applicable withholding of
Federal and state taxes. The Company may, at its election, pay such difference
in cash or in shares of Common Stock valued at the fair market value of the
Common Stock on the day preceding the date of payment. In no event may (i) an
aggregate payment by the Company during any fiscal year upon the exercise of
SARs exceed $100,000, or (ii) a holder of an SAR, who is also an employee of the
Company or its subsidiaries, exercise an SAR if the aggregate amount to be
received as a result of his or her exercise of SARs in the preceding 12 month
period exceeds such employee's current base salary, in each case except as may
otherwise be permitted by the Compensation Committee.
    
 
   
     Options Issued Under the Omnibus Plan.  The terms of specific options are
determined by the Compensation Committee. Generally, options will be granted at
an exercise price equal to at least 100% of fair market value of the Common
Stock on the date of grant. Each option will be exercisable after the period or
periods specified in the option agreement, which will generally not exceed 10
years from the date of grant. Options may be issued in tandem with SARs ("Tandem
Options") as a performance award. Upon the exercise of an option, the option
holder will pay to the Company the exercise price plus the amount of the
required Federal and state withholding taxes, if any.

     Performance Awards Consisting of Options and SARs Issued in Tandem Under
the Omnibus Plan. Upon exercise of a Tandem Option, the optionee will be
entitled to a credit toward the exercise price equal to the value of the SARs
issued in tandem with the option exercised, but not to exceed the amount of the
Federal income tax deduction allowed to the Company in respect of such SAR and
not in an amount which would reduce the amount of payment by the optionee below
the par value of the shares being purchased. Upon exercise of a Tandem Option,
the related SAR will terminate, the value being limited to the credit which can
be applied only toward the purchase price of Common Stock. In all cases, full
payment of the net purchase price of the shares must be made in cash or its
equivalent at the time the Tandem Option is exercised, together with the amount
of the required Federal and State withholding taxes, if any. When a SAR issued
as part of a Tandem Option is exercised, the option to which it relates will
cease to be exercisable to the extent of the number of shares with respect to
which the SAR was exercised.
 
     Other Performance Awards Issued Under the Omnibus Plan.  The Omnibus Plan
authorizes the Compensation Committee to grant, to the extent permitted under
Rule 16b-3 promulgated by the SEC under the Exchange Act, and applicable law,
other Awards that are denominated or payable in, valued by reference to, or
otherwise based on or related to shares of Common Stock. Furthermore, the amount
or terms of an Award may be related to the performance of the Company or to such
other criteria or measure of performance as the Compensation Committee may
determine.
 
The Company's 1995 Stock Option Plan
 
     The Company's 1995 Stock Option Plan (the "Stock Option Plan") is intended
to encourage ownership of Common Stock by officers and other key employees and
advisors of the Company, to encourage their continued employment with the
Company and to provide them with additional incentives to promote the success of
the Company.
 
   
     The Stock Option Plan authorizes the grant to officers, key employees, and
directors of awards ("Awards") consisting of "incentive stock options," as that
term is defined under the provisions of Section 422 of the Code, and
non-qualified stock options. There were 1,600,000 shares of Common Stock
available for granting Awards under the Stock Option Plan. The Compensation
Committee of the Board (the "Committee") administers the Stock Option Plan and
has sole discretion to determine those employees to whom Awards will be granted,
the number of Awards granted, the provisions applicable to each Award and the
time periods during which Awards may be exercisable.
    
 
     The Committee may grant incentive stock options, non-qualified stock
options, or a combination of the two. The exercise price of each incentive stock
option may not be less than the fair market value of the Common Stock at the
date of grant. Under the Stock Option Plan, fair market value is generally
determined in accordance with procedures established by the Committee. The
option price per share of any non-qualified stock option is determined by the
Committee on the date the option is granted. The exercise price of each
incentive stock option granted to any stockholder possessing more than 10% of
the combined voting power of all classes of capital stock of the Company, or, if
applicable, a parent or subsidiary of the Company, on the date of grant must not
be less than 110% of the fair market value on that date, and no such option may
be exercisable more than five years after the date of grant.
 
     Options granted are exercisable for a term of not more than ten years from
the date of grant. In addition, no employee may be granted an incentive stock
option to the extent the aggregate fair market value, as of the date of grant,
of the stock with respect to which incentive stock options are first exercisable
by such employee during any calendar year exceeds $100,000.
 
     Awards granted under the Stock Option Plan are subject to adjustment upon a
recapitalization, stock split, stock dividend, merger, reorganization,
liquidation, extraordinary dividend, or other similar event affecting the Common
Stock. An Award is not transferable, other than by will or the laws of descent
and distribution or, in certain circumstances, pursuant to a qualified domestic
relations order, and an Award may be exercised, during the lifetime of the
holder of the Award, only by the holder, or the holder's personal representative
in the event of disability.

<PAGE>   48
 
     The Stock Option Plan terminates on February 1, 2005, and Awards will not
be granted under the Stock Option Plan after that date, although the terms of
any Award may be amended in accordance with the Stock Option Plan at any date
prior to the end of the term of such Award. Any Awards outstanding at the time
of termination of the Stock Option Plan continue in full force and effect
according to the terms and conditions of the Award and the Stock Option Plan.
 
   
     The Stock Option Plan may be amended by the Committee, subject to approval
of the Board, but no amendment may impair any rights of any holder of an Award
previously granted under the Stock Option Plan without the holder's consent. As
of May 15, 1997, options for 740,000 shares were outstanding, options for 77,500
shares had been granted and exercised, and options for 482,500 shares were
unissued.
    
 
The Company's Employee Stock Purchase Plan
 
   
     The Company's Employee Stock Purchase Plan (the "Stock Purchase Plan") was
approved by the Company's Board and shareholders in May 1997. There are reserved
for issuance upon the exercise of Options to be granted under the Stock Purchase
Plan an aggregate of 500,000 shares of Common Stock, subject to adjustment upon
the occurrence of certain specific capitalization events.
    
 
   
     The Stock Purchase Plan is intended to encourage ownership of Common Stock
by eligible employees of the Company, to encourage their continued employment
with the Company and to provide them with additional incentives to promote the
success of the Company. Except as discussed below, eligible employees are
employees who have been employed by the Company or any of its subsidiaries for
at least six months and who customarily work more than 20 hours per week and
five months per calendar year.
    
 
     The Stock Purchase Plan authorizes the Compensation Committee to grant
options to purchase shares of Common Stock to eligible employees pursuant to one
or more offerings to be made under the Stock Purchase Plan. The Compensation
Committee administers the Stock Purchase Plan and has sole discretion to
determine when offerings will be made under the Stock Purchase Plan, the number
of shares of Common Stock to be made available in any such offering, the length
of the period pursuant to which employees can elect to participate in any
offering (the "Subscription Period") and the period pursuant to which
installment obligations of the option price must be paid (the "Purchase
Period"). The Subscription Period and Purchase Period of any offering made under
the Stock Purchase Plan may not together exceed 27 months.
 
   
     The Compensation Committee may exclude the employees of any specific
subsidiary from any offering made under the Stock Purchase Plan and may
determine not to include certain highly compensated employees. In addition, no
option may be granted to an employee who, immediately after the option is
granted, owns 5% or more of the value or voting power of all classes of stock of
the Company or its parent, if any, or subsidiary corporations, after taking into
account certain attribution rules. Subject to these provisions, all eligible
employees must be given the right to participate in any offering made under the
Stock Purchase Plan.
    
 
   
     Prior to any offering made under the Stock Purchase Plan, the Company will
grant to each employee eligible to participate in the offering the right to
subscribe for an option to purchase on the last business day of the Purchase
Period applicable to such offering at a price determined by the Compensation
Committee, the number of full shares of Common Stock which such employee's
accumulated payroll deductions will purchase as of the last business day of the
Purchase Period. Unless the Compensation Committee determines otherwise, the
option price will equal 85% of the fair market value of the Common Stock on the
first day of the Purchase Period. Employees may elect to subscribe for options
to purchase shares of Common Stock for an aggregate purchase price up to a
specified percentage of their annual compensation as determined by the
Compensation Committee for a particular offering.
    
 
     On the first day of the Purchase Period, eligible employees who elect to
participate in an offering will receive, subject to certain limitations set
forth in the Stock Purchase Plan, an option to purchase the number of shares for
which such employee has subscribed. These options will be automatically
exercised as of the last business day of the Purchase Period.
 
                                       45
<PAGE>   49
 
     Subject to certain limitations set forth in the Stock Purchase Plan, an
employee is permitted, at any time prior to the end of the Purchase Period
applicable to such offering, to terminate or reduce his or her payroll
deductions, to reduce his or her options to purchase or to withdraw all or part
of the amount in his or her account, without interest. Upon the termination of
the employee's employment with the Company prior to the last day of the Purchase
Period for any reason other than death or retirement, the employee's only right
will be to receive the amount of cash then in such employee's account, without
interest.
 
     Options granted under the Stock Purchase Plan will be subject to adjustment
upon a recapitalization, stock split, stock dividend, merger, reorganization,
liquidation, extraordinary dividend or other similar event affecting the Common
Stock. Options will not be transferable, other than by will or the laws of
descent and the distribution, or if permitted pursuant to the Code, and the
Regulations thereunder without affecting the option's qualification under
Section 423 of the Code, pursuant to a qualified domestic relations order, and
an option may be exercised, during the lifetime of the holder of the option,
only by such option holder, or his or her personal representative in the event
of disability.
 
     In the case of an unusual corporate event such as liquidation, merger,
reorganization (other than a reorganization as defined by Section 368(a)(1)(F)
of the Code), or other business combination, acquisition or change in control of
the Company through a tender offer or otherwise, the Board may, in its sole
discretion, determine to terminate the Purchase Period of any offering made
under the Stock Purchase Plan as of the last day of the month during which such
unusual corporate event occurs, but in the event of any such termination, an
option holder will have the right, commencing at least five days prior to the
unusual corporate event, to either make a lump sum payment equal to the
remaining portion of the purchase price payable under his or her option or to
cancel his or her election to purchase shares pursuant to such option.
 
     The Stock Purchase Plan will terminate ten years from the date of adoption,
and an option shall not be granted under the plan after such date. Any options
outstanding at the time of termination of the Stock Purchase Plan will continue
in full force and effect according to the terms and conditions of the Stock
Purchase Plan.
 
   
1997 Non-Employee Director Stock Option Plan
    
 
   
     The Company's 1997 Non-Employee Director Stock Option Plan (the "Director
Plan") was approved by the Company's Board and shareholders in May 1997. An
aggregate of 150,000 shares of Common Stock have been reserved for issuance
under the Director Plan, subject to adjustment upon the occurrence of certain
specified capitalization events.
    
 
   
     The Director Plan is intended to encourage non-employee directors of the
Company to acquire or increase their ownership of Common Stock on reasonable
terms and to foster a strong incentive for non-employee directors to put forth
maximum effort for the continued success and growth of the Company. The Director
Plan will become effective as of the completion of the Offering and will
terminate ten years from that date.
    
 
   
     Each non-employee director who becomes a member of the Board subsequent to
the closing of this Offering shall automatically be granted an option to
purchase 3,000 shares of Common Stock. In addition, on each anniversary of the
date the Director Plan becomes effective, each of the Company's then
non-employee directors who have served as directors for at least six (6) months
shall automatically be granted an option to purchase 5,000 shares of Common
Stock. The per share exercise price of options granted under the Director Plan
will be the fair market value of the Common Stock on the date of grant. The
exercise price of options granted under the Director Plan is payable in cash or
in shares of Common Stock valued at fair market value at the time of exercise,
or a combination of cash and shares; however, the Company may establish
"cashless exercise" procedures, subject to applicable laws, rules and
regulations, pursuant to which a director may exercise an option and arrange for
a simultaneous sale of the underlying Common Stock, with the exercise price
being paid from the proceeds of such sale. Options granted under the Director
Plan will expire ten years after the date of grant, subject to earlier
termination, and may be exercised as follows: twenty-five percent (25%) after
one (1) year from the date of grant, fifty percent (50%) after two (2) years
from the date of
    
 
                                       46
<PAGE>   50
 
   
grant, seventy-five percent (75%) after three (3) years from the date of grant
and one hundred percent (100%) after four (4) years from the date of grant.
    
 
   
     In the event that a director ceases to be a member of the Board (other than
by reason of death or disability), an option may be exercised by the director
(to the extent the director was entitled to do so at the time he or she ceased
to be a member of the Board) at any time within three months after he or she
ceases to be a member of the Board, but not beyond the term of the option. If
the director dies or becomes disabled while he or she is a member of the Board,
or within three months after he or she ceases to be a member of the Board, the
option may be exercised (to the extent the director was entitled to do so at the
time of his or her death) in full by his or her personal representative or
distributees at any time within one year after his or her death or disability,
but not beyond the term of the option. In the event of the occurrence of a
Change in Control (as defined in the Director Plan) a director would be entitled
to exercise the option in full, but such option would terminate 90 days after
the Change in Control.
    
 
   
     The Director Plan will be administered by the Compensation Committee. The
principal terms of the option grants are set forth in the Director Plan,
therefore, the Compensation Committee will have no discretion to select which
directors receive options, the number of shares of Common Stock subject to
options or the exercise price of options.
    
 
   
     Each of the above plans may be amended at any time and from time to time by
the Board of Directors, but no amendment without the approval of the
shareholders of the Company shall be made if shareholder approval would be
required under applicable law. No amendment may, however, impair the rights or
obligations of the holder of any option granted under the Omnibus Plan, the
Stock Purchase Plan or the Director Plan without his or her consent.

                              CERTAIN TRANSACTIONS
 
     The following summarizes certain material agreements between the Company
and its officers, directors and certain of its existing shareholders. The
summary is not a complete description of such agreements and therefore this
discussion is qualified in its entirety by reference to the agreements, copies
of which will be made available for inspection upon written request to the
Company. It is the Company's intention that in the future, transactions with
directors, officers, employees or affiliates of the Company will be minimal and
will be approved in advance by a majority of the disinterested members of the
Company's Board of Directors.
 
REGISTRATION RIGHTS AGREEMENTS
 
     Several of the officers, directors and holders of more than 5% of the
Common Stock have entered into registration rights agreements relating to shares
of Preferred Stock or Common Stock. See "Description of Capital Stock --
Registration Rights Agreements."
 
1997 NOTES, 1997 WARRANTS AND STOCKHOLDER GUARANTEE
 
   
     In March 1997, the Company entered into the Note Purchase Agreement with
respect to the 1997 Notes and entered into the 1997 Warrant Agreement with
respect to the 1997 Warrants. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources" and "Description of Capital Stock -- 1997 Warrants." The parties to
the Note Purchase Agreement and the holders of the 1997 Warrants include several
of the Company's significant stockholders or their affiliates. The following
significant shareholders, or their affiliates, agreed to acquire the indicated
percent of any 1997 Note that may be issued by the Company: Brantley Capital
Corporation -- 21%; IPP95, L.P. -- 20%; River Cities Capital Fund Limited
Partnership -- 9%; and Environmental Opportunities Management Co., LLC -- 20%.
These stockholders and the other parties to the Note Purchase Agreement (other
than the Company) have received, and will be entitled to receive, 1997 Warrants
as and when issued in accordance with the 1997 Warrant Agreement, pro rata in
proportion to the principal amount of 1997 Notes to be issued to such purchaser.
In the event (i) the Offering is completed at a price of $9.00 per share or
greater and (ii) either the Offering is completed within 180 days of the date of
sale of the 1997 Notes or there have been no 1997 Notes sold, then the Company
will have issued a minimum of 125,000 Warrants (if no 1997 Notes are sold) and a
maximum of 425,000 Warrants (if all $10,000,000 of 1997 Notes are sold). In the
event the Offering referred to in the preceding sentence is completed at a price
of less than $9.00 per share, then the Company will have also issued an
additional number of 1997 Warrants equal to 25% of the then outstanding 1997
Warrants. As of the date of this Prospectus, none of the 1997 Notes are
outstanding, and 125,000 of the 1997 Warrants are issued and outstanding. The
Company intends to repay all outstanding 1997 Notes, if any, in full upon
completion of the Offering. The Note Purchase Agreement will terminate upon the
closing of the Offering.
    
 
   
     Brantley Venture Partners III, L.P. ("Brantley"), a holder of 33.05% of the
Common Stock prior to the Offering, has guaranteed through June 1, 1997 up to
$2,000,000 of the Company's indebtedness under the Credit Facility in the event
the Company defaults on its payment obligations thereunder. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations --
Liquidity and Capital Resources." The Company paid no consideration to Brantley
for this guarantee. To the extent that Brantley makes a payment under its
guarantee of the Company's indebtedness under the Credit Facility, the amount of
such payments will be deemed to be an advance under the 1997 Notes from the date
of such payment. Robert P. Pinkas, a director of the Company, is an affiliate of
Brantley Capital Corporation and Brantley. See "Management -- Directors and
Executive Officers." In management's opinion, it is not likely that Brantley
will become obligated to make a payment pursuant to such guarantee, either prior
to completion of the Offering or thereafter.

The promissory note accrues interest at 10% per annum and is due and payable on
August 1, 1997. The promissory note is subordinated to the Company's obligations
to the Bank.
 
ADDITIONAL OPTIONS
 
     In June 1996, Robert P. Pinkas, a director of the Company, was granted an
option to purchase 100,000 shares of Common Stock at an exercise price of $4.00
per share pursuant to the Stock Option Plan.
 
LEASE TRANSACTIONS
 
     Waterlink Technologies is the tenant under two industrial building leases
in West Palm Beach, Florida (the "West Palm Building") and in Clearwater,
Florida (the "Clearwater Building"). Lawrence and Theresa H. Stenger, the
beneficial owners of more than 5% of the Common Stock and former owners of
Waterlink Technologies, are the direct or indirect landlords of the two
buildings. Both leases are dated as of September 30, 1996 and have a term of
five years. The leases may be renewed for two additional terms of two years
each. The annual base rent for the West Palm Building is $222,220. The annual
base rent for the Clearwater Building is $17,728. The annual base rent for the
third, fourth and fifth years of each lease increases to reflect the change in
the consumer price index, as defined in the lease.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon the closing of the Offering and assuming (i) no exercise of
outstanding options or warrants and (ii) conversion of all outstanding shares of
the Company's preferred stock, 10,932,554 shares of Common Stock will be
outstanding. Of such shares, the 4,500,000 shares sold in the Offering, and any
of the 675,000 shares which may be sold upon exercise of the Underwriters'
over-allotment option, will be freely tradable by persons other than
"affiliates" of the Company, as that term is defined in Rule 144 under the
Securities Act. The remaining 6,432,554 shares of Common Stock are "restricted
securities" within the meaning of Rule 144 (collectively, the "Restricted
Shares"). The Restricted Shares may not be sold unless they are registered under
the Securities Act or sold pursuant to an applicable exemption from
registration, including an exemption pursuant to Rule 144 under the Securities
Act. Holders of approximately 6,215,054 Restricted Shares have certain
registration rights pursuant to certain registration rights agreements. See
"Description of Capital Stock -- Registration Rights Agreements."
    
 
     The Company intends to register the shares of Common Stock reserved or to
be available for issuance pursuant to the Stock Option Plan. Following the
closing of the Offering, shares of Common Stock issued pursuant to the Stock
Option Plan generally will be available for sale in the open market by holders
who are not affiliates of the Company and, subject to the volume and other
limitations of Rule 144, by holders who are affiliates of the Company. In
addition, each director who is not an employee of the Company has been granted
an option to purchase shares of Common Stock. See "Management -- Compensation of
Directors."
 
     In connection with entering into the Credit Facility and commitments to
purchase subordinated indebtedness, the Company issued warrants to purchase
350,000 shares of Common Stock. Pursuant to the applicable warrant agreements,
the holders of such warrants have certain rights to require the Company to
register the shares of Common Stock to be issued upon exercise of the warrants.
 
   
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned Restricted Shares for at
least one year, including persons who may be deemed to be "affiliates" of the
Company, as that term is defined under Rule 144, may sell within any three-month
period a number of Restricted Shares that does not exceed the greater of one
percent of the then outstanding shares of Common Stock (estimated to be
10,932,554 shares after completion of this Offering, or 11,607,554 shares if the
Underwriters' over-allotment option is exercised in full) or the average weekly
trading volume of the Common Stock on the open market during the four calendar
weeks preceding such sale. Sales under Rule 144 are also subject to certain
manner-of-sale limitations, notice requirements, and the availability of current
public information about the Company. Pursuant to Rule 144(k), a person (or
persons whose shares are aggregated) who is deemed not to have been an
"affiliate" of the Company during the three months preceding
    
 
                                       51
<PAGE>   55
 
   
a sale, and who has beneficially owned Restricted shares for at least two years,
would be entitled to sell such shares under Rule 144 without regard to the
volume limitations, manner-of-sale provisions or notice requirements. Restricted
Shares properly sold in reliance upon Rule 144 are thereafter freely tradable
without restrictions or registration under the Securities Act, unless thereafter
held by an "affiliate" of the Company. The foregoing summary of Rule 144 is not
intended to be a complete description thereof. Absent additional offerings that
are registered under the Securities Act and any additional issuances of Common
Stock not referred to above, it is anticipated that as much as 6,317,554 shares
of Common Stock may be eligible to be sold pursuant to Rule 144 within
approximately one year of the closing of the Offering, of which approximately
1,855,000 shares of Common Stock may be immediately eligible to be sold (subject
to the Lockup Period referred to below).
    
 
   
     An employee, officer or director of or consultant to the Company who
purchased or was awarded shares or options to purchase shares pursuant to a
written compensatory plan or contract is entitled to rely on the resale
provision of Rule 701 under the Securities Act, which permits affiliates and
non-affiliates to sell their Rule 701 shares without having to comply with Rule
144's holding period restrictions, commencing 90 days after the effectiveness of
the Offering. In addition, non-affiliates may sell Rule 701 shares without
complying with the public information, volume and notice provisions of Rule 144.
Approximately 192,500 shares of Common Stock currently outstanding may be sold
pursuant to Rule 701.
    
 
     The Company, its officers and directors, and the holders of substantially
all of the Common Stock have agreed that, until the later of December 31, 1997
or 180 days following the date of this Prospectus, they will not, without the
prior written consent of Smith Barney Inc., offer, sell, contract to sell or
otherwise dispose of any shares of Common Stock, or any securities convertible
into, or exercisable or exchangeable for, Common Stock, except that the Company
may grant warrants pursuant to the Note Purchase Agreement and grant options
under the Company's stock option and purchase plans, and may issue shares of
Common Stock (i) in connection with acquisitions, (ii) pursuant to the exercise
of options granted under the Company's stock option and purchase plans, (iii)
pursuant to the exercise of warrants outstanding as of the closing of the
Offering or which the Company is obligated to issue as part of the 1997
Warrants, (iv) pursuant to the conversion of the Company's preferred stock and
(v) pursuant to or in connection with the Company's Rights Plan.
 
   
     The Company intends to register 5,000,000 shares of Common Stock under the
Securities Act during 1997 for its use in connection with future acquisitions.
These shares generally will be freely tradable after their issuance by persons
not affiliated with the Company; however, sales of these shares during the
Lockup Period would require the prior written consent of Smith Barney Inc.
    
 
     Prior to the Offering there has been no market for the Common Stock, and no
prediction can be made as to the effect, if any, that sales of Restricted
Shares, or the availability of Restricted Shares for sale, by existing
shareholders in reliance upon Rule 144, pursuant to registration or otherwise
will have on the market price of Common Stock. The sale by the Company or the
shareholders referred to above of a substantial number of shares of Common Stock
after the Offering could adversely affect the market price for the Common Stock.

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
   
     Upon completion of the Offering, the authorized capital stock of the
Company will consist of 40,000,000 shares of Common Stock, par value $.001 per
share, and 10,000,000 shares of preferred stock, par value $.001 per share (the
"Preferred Stock"), of which 10,932,554 shares of Common Stock will be issued
and outstanding and no shares of Preferred Stock will be issued and outstanding.
Prior to the completion of this Offering, the authorized capital stock of the
Company included 440,000 shares of Series A Preferred Stock, par value $.001 per
share, of which 400,000 shares were issued and outstanding, 1,836,000 shares of
Series B Preferred Stock, par value $.001 per share, of which 1,700,000 shares
were issued and outstanding, and 1,647,000 shares of Series C Preferred Stock,
par value $.001 per share, of which 1,150,000 shares were issued and
outstanding. Prior to the completion of the Offering, all outstanding shares of
the Company's preferred stock will be converted into Common Stock in accordance
with the terms of such preferred stock, and such preferred stock will no longer
be authorized or outstanding. An aggregate of 3,250,000 shares of Common Stock
will be issued upon the conversion of all outstanding shares of the Company's
preferred stock, which shares of Common Stock are included in the number of
shares of Common Stock to be outstanding upon the completion of the Offering, as
set forth above.
    
 
     The following summary of certain provisions of the Common Stock does not
purport to be complete and is subject to, and qualified in its entirety by, the
provisions of the Company Certificate and the Company Bylaws to be in effect
upon the closing of the Offering, the form of each of which is included as an
exhibit to the Registration Statement of which this Prospectus is a part, and by
the provisions of applicable law.
 
COMMON STOCK
 
     The holders of Common Stock are entitled to one vote for each share held of
record by them upon all matters to be voted on by the holders of Common Stock.
The holders of Common Stock are entitled to participate equally in all dividends
payable with respect to the Common Stock subject to any preferences or rights of
any outstanding preferred stock. In the event of liquidation, dissolution or
winding up of the affairs of the Company, the holders of Common Stock are
entitled to share ratably in all assets of the Company remaining available for
distribution to them after payment of liabilities and after provision has been
made for each class of stock, including any preferred stock, that has preference
over the Common Stock. Holders of shares of Common Stock, as such, have no
conversion rights, and there are no redemption or sinking fund provisions
applicable to the Common Stock. All of the outstanding shares of Common Stock
are fully paid and nonassessable.
 
PREFERRED STOCK
 
     Effective upon the closing of the Offering, the Board of Directors will
have the authority, without any further vote or action by the stockholders, to
provide for the issuance of up to 10,000,000 shares of Preferred Stock from time
to time in one or more series and to fix such designations, rights, preferences
and limitations as the Board of Directors may determine, including the
consideration received therefor, the number of shares comprising each series,
dividend rates, redemption provisions, liquidation preferences, sinking fund
provisions, conversion rights and voting rights, including Series 1 Preferred
Stock (the "Series 1 Preferred Stock") authorized in connection with the
Stockholders Rights Plan described below. Although it is not possible to state
the effect that any issuance of Preferred Stock might have on the rights of
holders of Common Stock, the issuance of Preferred Stock may have one or more of
the following effects: (i) restrict Common Stock dividends if Preferred Stock
dividends have not been paid; (ii) dilute the voting power and equity interests
of holders of Common Stock to the extent that any Preferred Stock series has
voting rights or is convertible into Common Stock; or (iii) prevent current
holders of Common Stock from participating in the Company's assets upon
liquidation until any liquidation preferences granted to holders of Preferred
Stock are satisfied. In addition, the issuance of Preferred Stock may, under
certain circumstances, have the effect of discouraging a change in control of
the Company by, for example, granting voting rights to holders of Preferred
Stock that require approval by the separate vote of the holders of Preferred
Stock for any amendment to the Company
 
                                       53
<PAGE>   57
 
Certificate or any reorganization, consolidation or merger (or other similar
transaction involving the Company). As a result, the issuance of such Preferred
Stock may discourage bids for the Company's Common Stock at a premium over the
market price therefor and could have a material adverse effect on the market
value of the Common Stock. The Board of Directors does not presently intend to
issue any shares of Preferred Stock, other than in connection with the
stockholders rights plan, referred to below.
 
REGISTRATION RIGHTS AGREEMENTS
 
     In connection with the issuance by the Company of all of the outstanding
shares of the Company's preferred stock (with the exception of 25,000 shares of
Series C Preferred Stock issued to one particular shareholder), the Common Stock
issued prior to the Offering (other than upon exercise of stock options) and any
securities of the Company convertible into or exchangeable for shares of Common
Stock (other than a stock option), including the 1997 Warrants, the Company
granted to holders thereof certain rights relating to registering the Common
Stock under the Securities Act.
 
     In general, the "Investors" as defined in the Amended and Restated
Registration Rights Agreement dated March 6, 1997 (the "Registration Rights
Agreement") (generally defined as substantially all holders of Series A
Preferred Stock, Series B Preferred and Series C Preferred Stock and 1997
Warrants) and Mr. Savastano may demand registration under the Securities Act of
the Common Stock issued upon the conversion of outstanding shares of the
Company's preferred stock and the exercise of the 1997 Warrants upon the request
of the Investors (treated as a single class and calculated on an "as converted
basis"). The Company will pay all registration expenses relating to such
registration. Each of the registration rights agreements otherwise contain such
terms and conditions ordinarily and customarily found in registration rights
agreements, including, without limitation, piggyback registration rights,
indemnification provisions, and holdback agreements.
 
STOCKHOLDER RIGHTS PLAN
 
   
     Effective upon the consummation of the Offering, the Board has adopted a
stockholder rights plan, pursuant to which one Right will be distributed for
each share of Common Stock. Each Right entitles the registered holder to
purchase from the Company one one-hundredth of a share of Series 1 Preferred
Stock at a price of $65.00 per one one-hundredth of a share of Series 1
Preferred Stock (the "Purchase Price"), subject to adjustment. The following
summary description of the Rights does not purport to be complete and is
qualified in its entirety by reference to the Rights Agreement (the "Rights
Agreement"), between the Company and American Stock Transfer & Trust Company, as
Rights Agent (the "Rights Agent"), the form of which is filed as an exhibit to
the Registration Statement of which this Prospectus is a part and is
incorporated herein by reference. See "Description of Capital Stock -- Preferred
Stock."
    
 
   
     Until the earliest to occur of (i) the first date of public announcement
that a person (other than the Company, any subsidiary of the Company, an
employee benefit plan of the Company or a subsidiary of the Company, or an
Exempt Person (defined below)) or group of affiliated or associated persons has
acquired, or obtain the right to acquire, beneficial ownership of 15% or more of
the outstanding shares of Common Stock (an "Acquiring Person") and (ii) the
tenth day (or such later date as may be specified by the Board prior to such
time as any person or group of affiliated or associated persons becomes an
Acquiring Person) after the date any person commences or announces its intention
to commence a tender offer or exchange offer, the consummation of which would
result in such person, together with its affiliates or associates becoming an
Acquiring Person (the earlier of such dates being hereinafter called the
"Distribution Date"), the Rights are evidenced by the certificates for shares of
Common Stock. "Exempt Persons" include any person who prior to this Offering was
the beneficial owner of 15% or more of the outstanding shares of Common Stock
for so long as (a) such person, together with all affiliates and associates
thereof, does not increase its percentage beneficial ownership by 1% or more of
the outstanding shares of Common Stock (b) there is no change of control of such
person, (c) such person, together with its affiliates or associates does not
commence a tender offer or exchange offer for Common Stock and (d) the Company
does not consolidate or merge with or into such person, or any of its affiliates
or associates, or sell, mortgage or otherwise transfer to such person, or any
    
 
                                       54
<PAGE>   58
 
of its affiliates or associates, assets or earning power representing 50% or
more of the assets or earning power of the Company.
 
     The Rights Agreement provides that, until the Distribution Date, the Rights
will be transferred with and only with shares of Common Stock. Until the
Distribution Date (or earlier redemption or expiration of the Rights),
certificates for shares of Common Stock issued after the date of the Rights
Agreement will contain a notation incorporating the Rights Agreement by
reference. Until the Distribution Date (or earlier redemption or expiration of
the Rights), the surrender for transfer of any certificates for shares of Common
Stock in respect of which Rights have been issued will also constitute the
transfer of the Rights associated with the shares of Common Stock represented by
such certificates. As soon as practicable following the Distribution Date,
separate certificates evidencing the Rights (the "Right Certificates") will be
mailed to holders of record of the shares of Common Stock as of the close of
business on the Distribution Date and such separate Right Certificates alone
will evidence the Rights.
 
     No Right will be exercisable at any time prior to the Distribution Date.
The Rights will expire on the tenth anniversary of the date of the Rights
Agreement (the "Final Expiration Date"), unless earlier redeemed or exchanged by
the Company as described below. 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.
 
     The Purchase Price payable, and the number of shares of Series 1 Preferred
Stock or other securities issuable, upon exercise of the Rights will be subject
to adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Series 1
Preferred Stock, (ii) upon the grant to holders of shares of Series 1 Preferred
Stock of certain rights or warrants to subscribe for or purchase shares of
Series 1 Preferred Stock at a price, or securities convertible into shares of
Series 1 Preferred Stock with a conversion price, less than the then current
market price of the shares of Series 1 Preferred Stock or (iii) upon the
distribution to holders of the shares of Series 1 Preferred Stock of evidences
of indebtedness or cash (excluding regular periodic cash dividends), assets,
stock (excluding dividends payable in shares of Series 1 Preferred Stock) or of
subscription rights or warrants (other than those referred to above).
 
     The number of outstanding Rights and the number of one one-hundredth of a
share of Series 1 Preferred Stock issuable upon the exercise of each Right also
will be subject to adjustment in the event of a stock dividend on the Common
Stock payable in shares of Common Stock or subdivision, combination or
reclassification of the Common Stock occurring, in any such case, prior to the
Distribution Date.
 
     Shares of Series 1 Preferred Stock issuable upon exercise of the Rights
will not be redeemable. Each share of Series 1 Preferred Stock will be entitled
to a minimum preferential quarterly dividend payment equal to the greater of (i)
$1.00 per share and (ii) an amount equal to 100 times the aggregate dividends
declared per share of Common Stock during the related quarter. In the event of
liquidation, the holders of the shares of Series 1 Preferred Stock will be
entitled to a preferential liquidation payment equal to accrued and unpaid
dividends thereon, plus the greater of (a) $100 per share and (b) an amount
equal to 100 times the liquidation payment made per share of Common Stock.
Finally, in the event of any merger, consolidation or other transaction in which
shares of Common Stock are exchanged, each share of Series 1 Preferred Stock
will be entitled to receive 100 times the amount received per share of Common
Stock. These rights are protected by customary antidilution provisions. Each
share of Series 1 Preferred Stock will have 100 votes, voting together with the
shares of Common Stock. In addition, in the event that the amount of accrued and
unpaid dividends on the Series 1 Preferred Stock is equivalent to six full
quarters dividends or more, the holders thereof shall have the right, voting as
a class, to elect two directors in addition to the directors elected by the
holders of the Common Stock.
 
     In the event that any person or group or affiliated or associated persons
becomes an Acquiring Person, proper provision shall be made so that each holder
of a Right, other than Rights that are or were owned beneficially by the
Acquiring Person (which, from and after the later of the Distribution Date and
the date of the earliest of any such events, will be void), will thereafter have
the right to receive, upon exercise thereof at the then current exercise price
of the Right, that number of shares of Common Stock (or, under certain
 
                                       55
<PAGE>   59
 
circumstances, an economically equivalent security or securities of the Company)
having a market value of two times the exercise price of the Right.
 
   
     To illustrate the operation of such an adjustment, at a Purchase Price of
$40.00, assuming the current market price (as determined pursuant to the
provisions of the Rights Agreement) per share of Common Stock was $4.00, each
Right not owned beneficially by an Acquiring Person at or after the time of such
an occurrence would entitle its holder to purchase (after the Distribution Date)
from the Company 20 shares of Common Stock (having an aggregate market value of
$80.00) for $40.00.
    
 
     In the event that, at any time after a person or group of affiliated or
associated persons has become an Acquiring Person, (i) the Company merges with
or into any person and the Company is not the surviving corporation, (ii) any
person merges with or into the Company and the Company is the surviving
corporation, but the shares of Common Stock are changed or exchanged, or (iii)
50% or more of the Company's assets or earning power are sold, proper provision
shall be made so that each holder of a Right will thereafter have the right to
receive, upon the exercise thereof at the then current exercise price of the
Right, that number of shares of common stock (or, under certain circumstances,
an economically equivalent security or securities) of such other person which at
the time of such transaction would have a market value of two times the exercise
price of the Right.
 
     At any time after the first date of public announcement that an Acquiring
Person has become such and prior to the acquisition by any person or group of
affiliated or associated persons of 50% or more of the outstanding shares of
Common Stock, the Board may exchange the Rights (other than any Rights which
have become void) for shares of Common Stock, in whole or in part, at an
exchange ratio of one share of Common Stock per Right (subject to adjustment).
 
     With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment in the Purchase
Price of at least 1%. The Company is not required to issue fractional shares of
Series 1 Preferred Stock (other than fractions which are integral multiples of
one one-hundredth of a share of Series 1 Preferred Stock, which may, at the
option of the Company, be evidenced by depositary receipts) or fractional shares
of Common Stock or other securities issuable upon the exercise of Rights. In
lieu of issuing such securities, the Company may make a cash payment, as
provided in the Rights Agreement.
 
     The Company may redeem all, but not less than all, the Rights at a price of
$.01 per Right (the "Redemption Price"), payable in cash or Common Stock, at any
time prior to such time as a person or group of affiliated or associated persons
becomes an Acquiring Person. Immediately upon any redemption of the Rights, the
right to exercise the Rights will terminate and the only right of the holders of
Rights will be to receive the Redemption Price.
 
     Prior to the Distribution Date, the Rights Agreement may be amended by the
Company without the approval of any holders of Rights. From and after the
Distribution Date, the Rights Agreement may be amended by the Company without
the approval of any holders of Rights in any manner which does not, in the good
faith determination of the Board, adversely affect the holders of the Rights
(other than an Acquiring Person), including amendments which add other events
requiring adjustment to the purchase price payable and the number of shares of
Series 1 Preferred Stock or other securities issuable upon the exercise of the
Rights or which modify procedures relating to the redemption of the Rights.
Under no circumstances may the Rights Agreement be amended to decrease the
stated Redemption Price or the period of time remaining until the Final
Expiration Date or to modify a time period relating to when the Rights may be
redeemed at such time as the Rights are not then 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 Board, except pursuant to an offer conditioned on a
substantial number of Rights being acquired. The Rights should not interfere
with any merger or other business combination approved by the Board since
(subject to the limitations described above) the Rights may be redeemed by the
Company at the Redemption Price prior to the time that a person or group has
become an Acquiring Person.

1997 WARRANTS
 
     In March 1997, in connection with its entering into the Note Purchase
Agreement relating to the 1997 Notes, the Company entered into a warrant
agreement (the "1997 Warrant Agreement") pursuant to which it agreed to issue
warrants (the "1997 Warrants") to persons agreeing to be purchasers of the 1997
Notes. Each 1997 Warrant entitles the holder to purchase one share of Common
Stock at an initial purchase price per share of $4.50 ("Exercise Price"). In the
event (i) the Offering is completed at a price of $9.00 per share or greater and
(ii) either the Offering is completed within 180 days of the date of sale of the
1997 Notes or there have been no 1997 Notes sold, then the Company will have
issued a minimum of 125,000 Warrants (if no 1997 Notes are sold) and a maximum
of 425,000 Warrants (if all $10,000,000 of 1997 Notes are sold). In the event
the Offering referred to in the preceding sentence is completed at a price of
less than $9.00 per share, then the Company will have also issued an additional
number of 1997 Warrants equal to 25% of the then outstanding 1997 Warrants. As
of the date of this Prospectus, none of the 1997 Notes are outstanding but
125,000 Warrants have been issued and are outstanding. The Company intends to
repay any 1997 Notes in full upon completion of the Offering, in which event no
additional 1997 Notes or 1997 Warrants will be issued. The Exercise Price of the
1997 Warrants is subject to adjustment upon the occurrence of certain events
such as the issuance of securities at prices less than the Exercise Price then
in effect, or upon stock splits, stock dividends, reorganizations, mergers or
consolidations. The Note Purchase Agreement will terminate upon the closing of
the Offering.
 
CERTAIN ANTI-TAKEOVER CONSIDERATIONS
 
     The Company Certificate and the Company Bylaws, each of which will become
effective upon completion of the Offering, contain certain provisions which
operate only with respect to an extraordinary corporate transaction involving
the Company (or any of its subsidiaries) and which are designed to encourage any
person who desires to take control of and/or acquire the Company to enter into
negotiations with the Board, thereby making more difficult the acquisition of
the Company by means of a tender offer, a proxy contest or other non-negotiated
means. In general, these provisions (i) provide for a classified Board from
which directors may only be removed for cause, by the affirmative vote of 80% of
all of the stockholders (ii) provide that only a majority of the Board shall
have the authority to fill vacancies on the Board, (iii) limit the right of
stockholders to amend the Company Certificate and the Company Bylaws, (iv)
eliminate the right of stockholders to call special meetings and to take action
without a meeting, (v) establish an advance notice procedure regarding the
nomination of directors by stockholders and stockholder proposals to be brought
before an annual meeting, and (vi) require that certain business combinations
either meet certain minimum price and procedural requirements, be approved by
the members of the Board who are unaffiliated with the persons seeking to effect
such business combinations or be approved by a supermajority stockholder vote.
In addition to encouraging any person intending to attempt a takeover of the
Company to negotiate with the Board, these provisions also curtail such person's
use of a dominant equity interest to control any negotiations with the Board.
Under such circumstances, the Board may be better able to make and implement
reasoned business decisions and protect the interests of all of the Company's
stockholders. A copy of the Company Certificate and the Company Bylaws are filed
as exhibits to the Registration Statement of which this Prospectus is a part.
 
Classified Board of Directors
 
     The Company Certificate provides for the Board to be divided into three
classes serving staggered terms so that directors' initial terms will expire at
the first, second or third scheduled annual meeting of stockholders. Starting
with the first scheduled annual meeting of the Company's stockholders, one class
of directors will be elected each year for a three-year term. See "Management --
Directors and Executive Officers." The classes will be as nearly equal in number
as possible. The classification of directors makes it more difficult for a
significant stockholder to change the composition of the Board in a relatively
short period of time and, accordingly, provides the Board and stockholders time
to review any proposal that a significant stockholder may make and to pursue
alternative courses of action which are fair to all the stockholders of the
Company.

Removal of and Filling Vacancies on the Board of Directors of the Company
 
     The Company Certificate provides that, subject to any rights of the holders
of Preferred Stock of the Company, only a majority of the Board then in office
or the sole remaining director shall have the authority to fill any vacancies on
the Board, including vacancies created by an increase in the number of
directors. Moreover, because the Company Certificate provides for a classified
board, Delaware law provides that the stockholders may remove a member of the
Board only for cause. The Company Certificate provides that the affirmative vote
of the holders of at least 80% of the voting power of stock entitled to vote
generally in the election of directors is required to remove a director for
cause. These provisions relating to removal and filling of vacancies on the
Board preclude stockholders from enlarging the Board or removing incumbent
directors and filling the vacancies with their own nominees.
 
Amendment of the Company Certificate and the Company Bylaws
 
     The Company Certificate contains provisions requiring the affirmative vote
of the holders of at least 80% of the voting power of the stock entitled to vote
generally in the election of directors to amend certain provisions of the
Company Certificate and the Company Bylaws (including certain of the provisions
discussed above). These provisions make it more difficult for stockholders to
make changes in the Company Certificate or the Company Bylaws, including changes
designed to facilitate the exercise of control over the Company.
 
Limitations on Stockholder Action by Written Consent; Special Meetings
 
     Meetings. The Company Certificate provides that stockholder action can be
taken only at an annual or special meeting of stockholders and prohibits
stockholder action by written consent in lieu of a meeting. The Company
Certificate and the Company Bylaws provide that, subject to the rights of
holders of any series of Preferred Stock, special meetings of stockholders can
be called only by a majority of the entire Board or by the President or Chairman
of the Board. Stockholders are not permitted to call a special meeting or to
require that the Board call a special meeting of stockholders. Moreover, the
business permitted to be conducted at any special meeting of stockholders is
limited to the business brought before the meeting by or at the direction of the
Board. These provisions prohibit a significant stockholder from proposing a
stockholder vote on issues not approved by the Board or from authorizing
stockholder action without a meeting at which all stockholders would be entitled
to participate.
 
     Nominations of Directors and Stockholder Proposals. The Company Bylaws
establish an advance notice procedure with regard to the nomination other than
by, or at the direction of, the Board of candidates for election as directors
(the "Nomination Procedure") and with regard to stockholder proposals to be
brought before an annual meeting of stockholders (the "Business Procedure"). The
Nomination Procedure provides that only persons who are nominated by, or at the
direction of, the 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, are eligible for election as directors of the Company. The Business
Procedure provides that to be properly brought before an annual meeting,
business must be specified in the notice of the annual meeting given by or at
the direction of the Board (or any duly authorized committee thereof) or brought
before the meeting by, or at the direction of, the 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. The notice from the stockholder must also meet
certain information requirements, as further set forth in the Company Bylaws.
 
     If the officer of the Company presiding at the meeting determines that a
person was not nominated in accordance with the Nomination Procedure, or that
other business was not brought before the meeting in accordance with the
Business Procedure, such person is not eligible for election as a director, or
such business is not to be conducted at such meeting, as the case may be.
 
     The purpose of the Nomination Procedure is, by requiring advance notice of
nomination by stockholders, to afford the Board a meaningful opportunity to
consider the qualifications of the proposed nominees and, to the extent deemed
necessary or desirable by the Board, to inform stockholders about such
qualifications. The purpose of the Business Procedure is, by requiring advance
notice of stockholder proposals, to provide a more
 
                                       58
<PAGE>   62
 
orderly procedure for conducting annual meetings of stockholders and, to the
extent deemed necessary or desirable by the Board, to provide the Board with a
meaningful opportunity to inform stockholders, prior to such meetings, of any
proposal to be introduced at such meetings, together with any recommendation as
to the Board's position or belief as to action to be taken with respect to such
proposal, so as to enable stockholders better to determine whether they desire
to attend such meeting or grant a proxy to the Board as to the disposition of
any such proposal. Although the Company Bylaws do not give the Board any power
to approve or disapprove stockholder nominations for the election of directors
or of any other proposal submitted by stockholders, the Company Bylaws may have
the effect of precluding a nomination for the election of directors or
precluding the conducting of business at a particular stockholder meeting if the
proper procedures are not followed, and may discourage or deter a third party
from conducting a solicitation of proxies to elect its own slate of directors or
otherwise attempting to obtain control of the Company, even if the conduct of
such solicitation or such attempt might be beneficial to the Company and its
stockholders.
 
Fair Price Provision
 
     Article Sixth of the Company Certificate (the "Fair Price Provision")
requires the approval by the holders of 80% of the voting power of the
outstanding capital stock of the Company entitled to vote on all matters
submitted to the stockholders, generally (the "Voting Stock") as a condition for
mergers and certain other business combinations ("Business Combinations")
involving the Company and any holder of more than ten percent (10%) of such
voting power (an "Interested Stockholder"), excluding Voting Stock beneficially
owned by the Interested Stockholder, unless the transaction is either (i)
approved by a majority of the members of the Board who are not affiliated with
the Interested Stockholder and who were directors before the Interested
Stockholder became an Interested Stockholder (the "Continuing Directors") or
(ii) certain minimum price and procedural requirements are met. These
requirements include that the aggregate amount of cash and the fair market value
(as defined), as of the date of the consummation of the Business Combination, of
consideration other than cash to be received per share by holders of capital
stock in such Business Combination shall be at least equal to the highest of (i)
the highest per share price paid by or on behalf of the Interested Stockholder
for any share of such capital stock in connection with the acquisition by the
Interested Stockholder of beneficial ownership of shares of such capital stock
(x) within the two-year period immediately prior to the first public
announcement of the proposed Business Combination (the "Announcement Date") or
(y) in the transaction in which it became an Interested Stockholder, or (ii) the
fair market value per share of such capital stock on the Announcement Date or on
the date on which the Interested Stockholder became an Interested Stockholder
(the "Determination Date"); or (iii) as to capital stock other than Common
Stock, the highest preferential amount per share to which the holders of shares
of such class or series of capital stock would be entitled in the event of any
voluntary or involuntary liquidation, dissolution or winding up of the affairs
of the Company regardless of whether the Business Combination to be consummated
constitutes such an event. Also, the consideration to be received by holders of
a particular class or series of outstanding capital stock must be in cash or in
the same form as previously paid by or on behalf of the Interested Stockholder
in connection with its direct or indirect acquisition of beneficial ownership of
shares of such class or series of capital stock. If the consideration so paid
for shares of any class or series of capital stock varied as to form, the form
of consideration for such class or series of capital stock must be either cash
or the form used to acquire beneficial ownership of the largest number of shares
of such class or series of capital stock previously acquired by the Interested
Stockholder. In addition, there cannot be any of several specified changes in
the payment of regular dividends or in the holdings of capital stock by such
Interested Stockholders after the Determination Date, nor can the Interested
Stockholders make any major change in the Company's business or equity capital
structure.
 
     The Fair Price Provision is designed to prevent a third party from
utilizing two-tier pricing and similar inequitable tactics in a takeover
attempt. The Fair Price Provision is not designed to prevent or discourage
tender offers for the Company. However, the separate provisions contained in the
Company Certificate and the Company Bylaws relating to "Classified Board of
Directors" and "Limitations on Stockholder Action by Written Consent; Special
Meetings" discussed above will, as therein indicated, curtail an Interested
Stockholder's ability to exercise control in several respects, including such
stockholder's ability to change incumbent directors who may oppose a Business
Combination or to implement a Business Combination by
 
                                       59
<PAGE>   63
 
written consent without a stockholder meeting. In addition, the Fair Price
Provision would discourage some takeover attempts by persons intending to
acquire the Company in two steps and to eliminate remaining stockholder
interests by means of a Business Combination involving less consideration per
share than the acquiring person would propose to pay for its initial interest in
the Company.
 
     In addition, the Company is subject to certain anti-takeover provisions of
the DGCL which prohibit the Company from engaging in any Business Combination
with any Interested Stockholder unless certain conditions are satisfied.

     The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock are
subject to approval of certain legal matters by their counsel and to certain
other conditions. The Underwriters are obligated to take and pay for all shares
of Common Stock offered hereby (other than those covered by the over-allotment
option described below) if any such shares are taken.
 
     The Underwriters, for whom Smith Barney Inc., Oppenheimer & Co., Inc. and
Sanders Morris Mundy Inc. are acting as representatives (the "Representatives"),
propose to offer part of the shares of Common Stock directly to the public at
the offering price set forth on the cover page of this Prospectus and part of
the shares to certain dealers at a price which represents a concession not in
excess of $       per share under the public offering price. The Underwriters
may allow, and such dealers may reallow, a concession not in excess of $
per share to certain other dealers. The Representatives of the Underwriters have
advised the Company that the Underwriters do not intend to confirm any shares to
any accounts over which they exercise discretionary authority. After the initial
public offering, the offering price and other selling terms may be changed by
the Representatives.
 
   
     The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an additional 675,000
shares of Common Stock at the price to the public set forth on the cover page of
this Prospectus, minus the underwriting discounts and commissions. The
Underwriters may exercise such option solely for the purpose of covering
over-allotments, if any, in connection with the Offering. To the extent such
option is exercised, each Underwriter will be obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
shares as the number of shares set forth opposite each Underwriter's name in the
preceding table bears to the total number of shares listed in such table.
    
 
                                       61

     The Company, its officers and directors, and the holders of substantially
all of the Common Stock have agreed that, until the later of December 31, 1997
or 180 days following the date of this Prospectus, they will not, without the
prior written consent of Smith Barney Inc., offer, sell, contract to sell or
otherwise dispose of any shares of Common Stock, or any securities convertible
into, or exercisable or exchangeable for, Common Stock, except that the Company
may grant warrants pursuant to the Note Purchase Agreement and grant options
under the Company's stock option and purchase plans, and may issue shares of
Common Stock (i) in connection with acquisitions, (ii) pursuant to the exercise
of options granted under the Company's stock option and purchase plans, (iii)
pursuant to the exercise of warrants outstanding as of the closing of the
Offering or which the Company is obligated to issue as part of the 1997
Warrants, (iv) pursuant to the conversion of the Company's preferred stock and
(v) pursuant to or in connection with the Company's Rights Plan.
 
     Prior to the Offering, there has not been any public market for the Common
Stock of the Company. Consequently, the initial public offering price for the
shares of Common Stock included in the Offering has been determined by
negotiations between the Company and the Representatives. Among the factors
considered in determining such price are the history of and prospects for the
Company's business and the industry in which it competes, an assessment of the
Company's management and the present state of the Company's development, the
past and present revenues and earnings of the Company, the prospects for the
growth of the Company's revenues and earnings, the current state of the economy
in the United States and the current level of economic activity in the industry
in which the Company competes and in related or comparable industries, and
currently prevailing conditions in the securities in the securities markets,
including current market valuations of publicly traded companies that are
comparable to the Company.
 
     On June 27, 1996, in a private placement of 1,150,000 shares of Series C
Preferred Stock by the Company for $4.00 per share, a Managing Director of Smith
Barney Inc., one of the Representatives, purchased 25,000 shares and two private
investment funds purchased an aggregate of 625,000 shares. The general partner
of the two private investment funds is Environmental Opportunities Management
Co., LLC, in which Sanders Morris Mundy, one of the Representatives, owns a 75%
interest. Shares of Series C Preferred Stock will convert on a one-for-one basis
into Common Stock on or prior to the closing of the Offering.
 
     In March 1997, the Company entered into the Note Purchase Agreement to
issue the 1997 Notes and entered into the 1997 Warrant Agreement to issue the
1997 Warrants. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations -- Liquidity and Capital Resources" and "Description
of Capital Stock -- 1997 Warrants." The two investment funds affiliated with
Sanders Morris Mundy, one of the Representatives, are parties to the Note
Purchase Agreement and are holders of 1997 Warrants.
 
     The Company has agreed to indemnify the Underwriters and certain related
persons against certain liabilities, including liabilities under the Securities
Act, or to contribute to payments that the Underwriters may be required to make
in respect thereof.
 
   
     The Representatives have advised the Company that, pursuant to Regulation M
under the Exchange Act, certain persons participating in the Offering may engage
in transactions, including stabilizing bids, syndicate covering transactions or
the imposition of penalty bids, which may have the effect of stabilizing or
maintaining the market price of the Common Stock at a level above that which
might otherwise prevail in the open market. A "stabilizing bid" is a bid for or
the purchase of the Common Stock on behalf of the Underwriters for the purpose
of fixing or maintaining the price of the Common Stock. A "syndicate covering
transaction" is the bid for or the purchase of the Common Stock on behalf of the
Underwriters to reduce a short position incurred by the Underwriters in
connection with the Offering. A "penalty bid" is an arrangement permitting the
Representatives to reclaim the selling concession otherwise accruing to an
Underwriter or syndicate member in connection with the Offering if the Common
Stock originally sold by such Underwriter or syndicate member is purchased by
the Representatives in a syndicate covering transaction and has therefore not
been effectively placed by such Underwriter or syndicate member. The
Representatives have advised the Company that such transactions may be effected
on The New York Stock Exchange or otherwise and, if commenced, may be
discontinued at any time.

                    SYSTEMS, EQUIPMENT AND SERVICES GLOSSARY
 
     AERATION SYSTEMS: The Company is a leader in the field of design,
manufacture and installation of JET AERATION and jet mixing systems for
industrial and municipal customers. It also offers a line of lower-cost
SUBMERGED MECHANICAL MIXERS for less demanding applications. Jet systems are
used to accomplish aeration, primarily for biological effluent treatment
processes but also for mixing, by creating high-velocity jets of air and process
water, or process water without air. Jet aeration accomplishes highly efficient
oxygen transfer and mixing to the process water or mixing alone if air
compressors are not operated. The high oxygen transfer rate of jet aeration can
increase the throughput capacity of a wastewater plant by 2-3 times compared to
fine bubble or coarse bubble aeration systems. In addition to higher aeration
efficiency, jet systems offer land use savings when applied to deep tank
applications, lower energy use, reduced aerosols, low installation costs,
convenient maintenance, and reduced clogging compared to conventional systems.
Industries in which jet aeration are well established include
chemical-petrochemical processing, food processing, pulp and paper plants,
refineries, and pharmaceutical plants, and municipal waste treatment.
Applications include conventional biological reactors, sequential batch reactors
(SBRs), autothermic thermophilic aerobic digesters (ATADs), complete mix
activated sludge, flow and organic equalization, as well as others. The
Company's jet aeration systems are provided by its Mass Transfer subsidiary and
are incorporated into the plant designs of Aero-Mod and Bioclear.
 
     CLARIFIERS: The Company, designs, builds and installs clarifiers for its
industrial and municipal customers. These devices remove, through gravity
settling, particulates from process water, producing a water which is clearer
than the influent and making it suitable for use in many industrial and
municipal applications. Particulates which are separated from the water are
settled to and removed from the bottom of the clarifier or raised to and removed
from the surface, most often in the form of a sludge. Although there are a
number of clarifier designs available in the marketplace, the Company utilizes a
patented technology in its all stainless steel CLARATOR(R)/SPLIT CLARATOR(TM)
clarifiers. The Company also manufactures INCLINED PARALLEL PLATE clarifiers,
which utilize a series of parallel plates mounted at an angle such that, as the
influent flows at a controlled rate up and over the plates, solids settle out
onto the plates, from which they slide downward to a sludge collection and
removal system. The advantage of an inclined plate clarifier is that the area
required for clarification is much smaller than that for a conventional
clarifier of equal removal capacity, saving up to 90% of space compared with a
conventional clarifier. The Company's Nordic Group, Great Lakes and Lanco
subsidiaries offer various application-specific clarifier configurations.
 
     CONTRACT OPERATIONS: The Company operates water purification and wastewater
treatment facilities for municipal customers under contract for varying time
periods. The Company currently operates small municipal wastewater treatment
facilities in the United States and Chile through its Aero-Mod subsidiary. In
addition, through its Bioclear subsidiary, the Company undertakes remote
monitoring of sequential batch reactor wastewater treatment systems for
industrial and municipal customers in the United States and Canada.
 
     CUTTING FLUID RECOVERY SYSTEMS: The Company's Sanborn Technologies
subsidiary manufactures separation systems for waste minimization and cutting
fluid recovery for machine tools and for treating similar industrial process
streams. Some of these systems incorporate membrane technology while others
incorporate centrifugal technology in the separation process. In both cases, the
Company's systems permit the removal and concentration of waste products from
the working fluid, leading to savings in both cutting fluid expense and disposal
costs.
 
     DESIGN/BUILD: The Company designs and constructs water purification and
wastewater treatment plants for a wide variety of applications. The Company's
design/build operations incorporate the Company's systems, equipment and
services, such as membrane systems, continuous recirculating sand filters,
sequential batch reactors, inclined plate clarifiers, sludge scrapers, and
aeration or mixing systems. The Company designs and constructs water
purification and wastewater treatment plants at its Axel-Johnson Engineering
GmbH, Bioclear, Aero-Mod and Waterlink Technologies subsidiaries.
 
     DEWATERING SYSTEMS: The Company offers many systems for dewatering sludge
from municipal and industrial treatment facilities. The Company manufactures
DECANTING CENTRIFUGES for the separation of solids
 
                                       65
<PAGE>   69
 
from sanitary sludge and industrial slurries. Decanters are utilized to achieve
a high level of dry solids in order to minimize waste volume and weight. The
Company's decanting centrifuges are capable of delivering up to 35% dry solids
because of very low differential speeds between the drum and shaft, providing
the Company a competitive advantage in cases where landfill disposal costs are
high. Decanting centrifuges, in addition to reducing disposal costs, are an
attractive alternative to other dewatering systems because they simplify plant
housekeeping, provide an improved working environment for operating personnel,
are highly reliable, are more compact and therefore require less floor space.
The Company's decanting centrifuges are manufactured by its Noxon subsidiaries.
They are marketed in Europe by Noxon and by the company's Sanborn Technologies
subsidiary in the Americas.
 
     The Company is the exclusive sales agent in North and South America for the
DRAIMAD(TM) DEWATERING-BAG SYSTEMS and the MONOBELT(TM) FILTER PRESSES
manufactured by Teknofanghi SA of Italy pursuant to a five-year agreement
expiring June 1, 2001. The MONOBELT(TM) is an all-stainless steel belt filter
press. In the MONOBELT(TM) system, the pressed sludge is scraped off the belt
and into a trough for disposal. The Company's belt filter presses are made or
distributed by its Aero-Mod subsidiary. The Company also manufactures
specialized manual and automatic PLATE AND FRAME FILTER PRESSES designed for
processing metal hydroxide sludges from metal finishing operations. Ancillary
products include steam and electric sludge dryers for eliminating even more
moisture prior to disposal. These presses are manufactured by Lanco. The
DRAIMAD(TM) dewatering-bag system is an all stainless steel, self-contained
system which delivers sludge under a slight pressure into porous bags from which
water is drained and returned to the treatment plant, whereas the
sludge-containing bags can be disposed of in a landfill. DRAIMAD(TM) systems are
marketed by Aero-Mod.
 
     FILTERS:  The Company offers a wide range of filters. With over 10,000
installations, the Company believes its CONTINUOUS RECIRCULATING SAND filter is
one of the best-known and respected filters in the world. Its unique design,
with no moving parts, produces a uniform, high quality filtrate. This filter is
used for the final filtration of biological wastewater plants, and can
accomplish phosphorous precipitation and nitrogen removal. Industrial
applications include effluent treatment for chemical, food processing, and
cellulose plants, metal hydroxide removal, mill scale recovery, and many others.
The continuous recirculating sand filter is normally supplied in multiple units
and can be fabricated from stainless steel, carbon steel, or can be designed for
concrete tanks. The Company's continuous recirculating sand filters are
manufactured by its Nordic Group subsidiary. They are marketed in Europe by the
Nordic Group and Axel Johnson Engineering GmbH. In the Americas they are
marketed by Waterlink Technologies. Multi-cell, multimedia automatic backwashing
TERTIARY POLISHING filters suitable for use on dissolved air flotation effluents
and inclined plate settler effluents are available from the Company's Great
Lakes subsidiary.
 
     The Company's Great Lakes subsidiary also manufactures a specialty ROTARY
VACUUM PRECOAT filter that is precoated with diatomaceous earth. The filter then
revolves through a reservoir which contains difficult waste streams which may be
very high in solids or which may be oily sludges. The precoated rotating drum
collects the waste material on the surface of the diatomaceous earth which is
slowly carved away by a knife edge. The dry waste material is subsequently
processed for disposal. The Company's rotary precoat filters are completely
automatic, highly reliable, and can be coupled with chemical pretreatment
systems to optimize efficiency.
 
     The Company's Waterlink Technologies subsidiary sells CARTRIDGE-REPLACEMENT
FILTERS and small water treatment systems to regional water treatment companies
that in turn sell to and service local commercial and residential customers.
 
     ION EXCHANGE MEDIA:  The Company designs and builds ion exchange MEDIA
RECHARGE products and services and demineralizing SYSTEMS. It also operates two
facilities in Florida that provide an exchange service for customers who use ion
exchange media for demineralizing water. These facilities reprocess the media to
restore its demineralizing capacity. The Company's Waterlink Technologies
subsidiary markets the ion exchange products and services.
 
     MEMBRANE SEPARATION SYSTEMS:  The Company's Waterlink Technologies
subsidiary designs and builds REVERSE OSMOSIS (RO) systems for DESALINATION,
drinking water treatment, wastewater reclamation, and process water production
for a wide variety of requirements including, for example, boiler feedwater, the
 
                                       66

beverage industry, and high purity applications for the pharmaceutical and
electronics industries. Desalination is the removal of inorganic solids (salts)
from a solution such as water to produce a liquid free of dissolved salts.
Desalination is typically accomplished by distillation, reverse osmosis, or
electrodialysis. The Company also produces ion exchange demineralizing systems,
microfiltration systems, and nanofiltration systems. In addition to large scale
industrial and municipal systems, the Company produces membrane systems for use
by commercial and residential customers which are normally sold through
distributors specializing in selling to and servicing a local customer base.
 
     NUTRIENT REMOVAL PROCESS: The Company's patented SEQUOX(TM) process for
biological nutrient removal accomplishes nitrification and denitrification to
meet United States tertiary wastewater regulations. The process features several
benefits including good control of filamentous organisms, reduced energy
consumption, carbon removal, nitrogen removal, and phosphorous removal. The
aeration system normally recommended for SEQUOX(TM) installations is jet
aeration from Mass Transfer, but SEQUOX(TM) installations may utilize
fine-bubble or coarse-bubble diffusers if the customer prefers. This process is
provided by the Company's Aero-Mod subsidiary. The Company also markets a DENI
PROCESS version for denitrification and an OXY PROCESS version for nitrification
marketed by Waterlink Technologies.
 
     OIL/WATER SEPARATORS:  The Company has a complete range of oil water
separators that are suitable for applications from the petroleum industry to the
food industry. The Company offers large scale systems for flows up to 5000
gallons per minute and small systems for the 0-35 gallons per minute range.
These systems are capable of removing oil down to 10 parts per million and are
certified to the DIN 1999 International Standard. Tanks are available in
fiberglass, carbon steel, and stainless steel for corrosion compatibility.
Emulsion breaking systems are available, as are chemical pretreatment systems.
The Company provides these separators through its Great Lakes and Zickert
Products subsidiaries.
 
     SEQUENTIAL BATCH REACTORS (SBRS):  The Company manufactures sequential
batch reactors for sanitary waste treatment plants that are subject to cold
weather, low flows, and facilities with high flow variation such as those found
in resort and seasonal sites. Sequential batch reactors are gaining favor with
regulatory officials in the United States because they are relatively simple to
operate and have an acceptable performance track record. A sequential batch
reactor system processes waste in batches instead of continuously, and consumes
less space than do conventional treatment plants. These batch reactor systems
have remote monitoring capabilities, enabling customers to benefit from weekly
process audits and remotely initiated corrections without the need for site
visits. These facilities are managed under annual monitoring contracts. These
sequential batch reactor systems are manufactured by Bioclear and can utilize
Mass Transfer's jet aeration systems, as well as Noxon and Aero-Mod's dewatering
products.
 
     SLUDGE SCRAPERS AND SKIMMERS:  The Company manufactures hydraulically and
electrically operated stainless steel surface and air flotation units. These are
employed in water treatment plants to remove sludge resulting from clarifiers,
either conventional or inclined plate settlers, from the surface of dissolved
air flotation tanks, and from rectangular wastewater plant clarifiers. The
market for scrapers is very competitive, and management believes that the
Company's offerings are at the high end with respect to quality, reliability,
and cost. These scrapers are typically sold on industrial systems or as
retrofits in the municipal market. These products are offered through the
Company's Zickert Products subsidiary in Europe and Asia Pacific and Waterlink
Technologies in the Americas.

                             BASIS OF PRESENTATION
 
   
     The following Unaudited Pro Forma Condensed Consolidated Balance Sheet as
of March 31, 1997 adjusts the Company's historical balance sheet to give effect
to the following as if they occurred as of March 31, 1997 (i) the completion of
the Pending Acquisitions, (ii) the conversion of all outstanding preferred
stock, and (iii) the sale of the 4,500,000 shares of Common Stock by the Company
in the Offering and the application of the estimated net proceeds therefrom as
described under "Use of Proceeds." The following Unaudited Pro Forma
Consolidated Statements of Operations for fiscal 1996 and the six months ended
March 31, 1996 and 1997 adjust the Company's historical statements of operations
to give effect to the events discussed in (i), (ii), and (iii) above and the
acquisitions completed during fiscal 1996 and fiscal 1997 as if they had
occurred as of October 1, 1995.
    
 
   
     The pro forma financial statements have been derived in part from the
historical financial statements included elsewhere in this Prospectus. In
preparing the pro forma financial statements, the historical financial
statements of the completed acquisitions and Pending Acquisitions were converted
to a September 30 fiscal year end, except for Bioclear Technologies, Inc. which
has an August 31 fiscal year end.
    
 
   
     The pro forma financial statements have been prepared by the Company based
in part on historical financial information provided by the management of the
Pending Acquisitions for periods prior to the consummation of these acquisitions
with respect to the historical results of operations and financial position of
Bioclear and Lanco. The related pro forma adjustments have been prepared by the
Company's management based on its assumptions and using the best available
information provided by the management of the Pending Acquisitions.
    
 
   
     The financial information for companies located outside the United States
(Nordic Group and Bioclear) have been presented in accordance with United States
generally accepted accounting principles. The exchange rates used to present
such financial information is located on page F-79 for the Nordic Group and
pages F-96 and F-97 for Bioclear.
    
 
   
     The Unaudited Pro Forma Condensed Consolidated Financial Data has been
prepared by the Company's management. This pro forma data does not purport to
represent the Company's financial position or results of operations had the
aforementioned transactions been completed as of the beginning of the periods
indicated, or to project the Company's results of operations at any future date
or for any future period. The Unaudited Pro Forma Condensed Consolidated
Financial Data should be read in conjunction with the Consolidated Financial
Statements and the notes thereto of the Company, the completed acquisitions and
the Pending Acquisitions, contained elsewhere in this Prospectus.

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED BALANCE SHEET ADJUSTMENTS
 
The Unaudited Pro Forma Condensed Consolidated Balance Sheet has been adjusted
to reflect the above as follows:
 
   
     (1)  To record the historical assets acquired and liabilities assumed in
          connection with the acquisitions of Bioclear and Lanco.
    
 
   
     (2)  To reflect adjustments to assets acquired and liabilities assumed in
          connection with the Pending Acquisitions based on their estimated fair
          values under the purchase method of accounting. The estimated combined
          purchase price relating to these acquisitions is $20,385,000,
          including acquisition related expenses of approximately $130,000. The
          allocation of the purchase price is preliminary and assumes the
          historical book value of tangible assets approximates fair value. The
          actual allocation will be based on management's final evaluation of
          such assets and liabilities. Some portion of the excess of the
          purchase price over the historical cost of net assets acquired may
          ultimately be allocated to specific tangible and intangible assets and
          liabilities. The final allocation of the purchase price and the
          resulting effect on net income may differ significantly from the pro
          forma amounts included herein. These pro forma adjustments are
          reflected as follows (in thousands of dollars):

   (11) To record interest expense of $2,706,000 in fiscal 1996, and $1,460,000
        and $1,038,000 for the six months ended March 31, 1996 and 1997,
        respectively, relating to debt assumed to be issued in connection with

        Proceeds."
    
 
   
   (14) Pro forma net income per share is computed by dividing net income by the
        number of shares used to compute pro forma per share data. For
        historical purposes, share data for the Company includes shares of
        Common Stock outstanding, shares of Common Stock to be issued upon the
        conversion of all outstanding Preferred Stock and the assumed exercise
        of outstanding stock options and warrants using the treasury stock
        method. For pro forma purposes, share data also includes shares of
        Common Stock to be issued in connection with the Pending Acquisitions.
        For pro forma as adjusted purposes, share data also includes shares of
        Common Stock to be issued in connection with the Offering. Shares
        associated with options, warrants, the Offering and the Pending
        Acquisitions were computed using an assumed initial public offering
        price of $11.00 per share.
    
 
   
   (15) The pro forma Statements of Operations exclude a special charge to
        operations of approximately $2.6 million ($0.13 per share, after tax),
        assuming an initial public offering price of $11.00 per share, which
        will be incurred in the quarter in which the Offering is completed. Such
        charge results primarily from the issuance by the Company of certain
        compensatory stock options to an officer of the Company pursuant to the
        terms of an employment agreement. Of this amount, approximately $1.1
        million is non-cash, and approximately $1.5 million represents cash
        payments relating principally to the reimbursement of income taxes
        resulting from this stock option issuance.

BOARD OF DIRECTORS
WATERLINK, INC.
 
     We have audited the accompanying consolidated balance sheets of Waterlink,

consolidated statements of operations, shareholders' equity and cash flows for
the period from December 7, 1994 (date of incorporation) to September 30, 1995
and for the year ended September 30, 1996. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Waterlink, Inc. and subsidiaries at September 30, 1995 and 1996, and the
consolidated results of their operations and their cash flows for the period

               (Information as of March 31, 1997 and for the six
    
   
               months ended March 31, 1996 and 1997 is unaudited)
    
 
1.   ACCOUNTING POLICIES
 
DESCRIPTION OF BUSINESS
 
Waterlink, Inc. (the "Company") operates in a single business segment, providing
integrated water and wastewater treatment solutions to industry and
municipalities worldwide, with sales primarily in the United States, Europe and
Latin America. Export sales represented more than one-third of sales in fiscal
1996. The Company has a strategy of acquisition and internal growth to provide
integrated products, technologies and services to water users globally.
 
PRINCIPLES OF CONSOLIDATION
 
   
The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiaries. All significant intercompany accounts and
transactions have been eliminated upon consolidation.
    
 
CASH EQUIVALENTS
 
The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
REVENUE RECOGNITION
 
The majority of the Company's systems and equipment are custom designed and take
a number of months to produce. Revenues from large contracts are recognized
using the percentage of completion method of accounting in the proportion that
costs bear to total estimated costs at completion. Revisions of estimated costs
or potential contract losses, if any, are recognized in the period in which they
are determined. Revenues from the remaining equipment and product sales are
recognized when shipped.
 
CONCENTRATIONS OF CREDIT RISK
 
Financial instruments which potentially subject the Company to concentrations of
credit risk consist principally of cash equivalents and trade receivables. The
Company places its cash equivalents with high quality financial institutions.
Concentrations of credit risk with respect to trade receivables are limited due
to the Company's large number of customers and their dispersion across many
different regions and industries. The Company grants credit to customers based
on an evaluation of their financial condition and collateral is generally not
required. Losses from credit sales are provided for in the financial statements
and have been within management's expectations.
 
FINANCIAL INSTRUMENTS
 
The carrying value of cash, cash equivalents, accounts receivable and accounts
payable are a reasonable estimate of their fair value due to the short-term
nature of these instruments. The Company's long-term debt, except for the notes
payable -- related parties, has a variable rate and cost approximates fair value
at September 30, 1996. The notes payable -- related parties do not have a ready
market and cost is assumed to approximate fair value. The carrying amount of
these notes is $3,100,000 at September 30, 1996, with interest rates ranging
from 5.61% to 10% and various maturity dates through April 2002.

               (Information as of March 31, 1997 and for the six
    
   
               months ended March 31, 1996 and 1997 is unaudited)
    
 
1.   ACCOUNTING POLICIES (CONTINUED)

INVENTORIES
 
Inventories are valued at the lower of cost or market. Cost is determined using
the first-in, first-out (FIFO) method.
 
PROPERTY, PLANT AND EQUIPMENT
 
Property, plant and equipment is valued at cost. Expenditures for repairs and
maintenance are charged to operations as incurred, while expenditures for
additions and improvements are capitalized. Depreciation is computed principally
using the straight-line method over the estimated useful lives of assets. The
useful lives range from 30 to 40 years for building and improvements; 5 to 10
years for machinery and equipment and 3 to 7 years for office equipment.
 
GOODWILL
 
Goodwill represents costs in excess of net assets of acquired businesses which
are amortized using the straight-line method over a period of 40 years. The
Company evaluates the realizability of goodwill based on the undiscounted cash
flows of the applicable businesses acquired over the remaining amortization
period. Should the review indicate that goodwill is not recoverable, the
Company's carrying value of goodwill would be reduced by the estimated shortfall
of the cash flows. No reduction of goodwill for impairment was necessary in 1995
or 1996.
 
DEMONSTRATION UNITS
 
   
Demonstration units are valued at cost and are amortized using the straight-line
method over a period of five years. Accumulated amortization on demonstration
units was $7,000 at September 30, 1995, $41,000 at September 30, 1996 and
$50,000 at March 31, 1997.
    
 
EMPLOYEE BENEFIT PLAN
 
   
Effective February 1, 1996, the Company implemented a defined contribution plan
which covers substantially all employees. No Company contributions were made to
the plan during the year ended September 30, 1996 or the six months ended March
31, 1997.
    
 
STOCK COMPENSATION
 
   
It is the Company's policy to generally grant stock options for a fixed number
of shares to employees with the exercise price approximating fair value. The
Company accounts for stock option grants in accordance with Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees,"
and, accordingly, recognizes no compensation expense for such stock option
grants. In certain instances where the exercise price is below fair value at the
date of grant, the Company recognizes compensation expense based on the
difference between the exercise price and fair value of such options ratably
over the vesting period.
    
 
USE OF ESTIMATES
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and

1.   ACCOUNTING POLICIES (CONTINUED)

disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
PRO FORMA NET INCOME PER SHARE
 
   
Pro forma net income per share is computed by dividing net income by the pro
forma weighted-average number of shares of Common Stock outstanding. These
shares include common shares outstanding, common shares to be issued upon the
conversion of outstanding Series A, Series B and Series C Preferred Stock and
the assumed exercise of outstanding stock options and warrants (using the
treasury stock method and an estimated initial public offering price of $11.00
per share). Historical per share amounts are not presented because such data is
not meaningful.
    
 
IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
In October 1995, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 123, Accounting for
Stock-Based Compensation, which provides an alternative to APB Opinion No. 25,
Accounting for Stock Issued to Employees, in accounting for stock-based
compensation issued to employees. The Company accounts for stock options in
accordance with APB Opinion No. 25. The disclosure requirements of SFAS No. 123
will be adopted as required for the Company's fiscal 1997 financial statements.
 
   
In February 1997, the FASB issued SFAS No. 128, Earnings Per Share. SFAS No. 128
replaces the presentation of primary earnings per share (EPS) under Accounting
Principles Board Opinion No. 15 and related Interpretations, with the
presentation of basic EPS (which primarily gives effect only to common shares
actually outstanding) and requires dual presentation of basic and diluted EPS on
the face of the income statement for all entities with complex capital
structures. The Company is required to adopt SFAS No. 128 during the first
quarter of fiscal 1998. The Company has not completed its evaluation of the
potential impact of this new standard on EPS in future periods.
    
 
INTERIM FINANCIAL INFORMATION
 
   
The accompanying consolidated balance sheet as of March 31, 1997, the related
consolidated statements of operations and cash flows for the six months ended
March 31, 1996 and 1997, and the consolidated statement of shareholders' equity
for the six months ended March 31, 1997 ("interim financial statements") have
been prepared by the Company in accordance with generally accepted accounting
principles for interim financial information and with Article 10 of Regulation
S-X. Accordingly, they do not include all of the information and footnotes
required by generally accepted accounting principles for complete financial
statements. The interim financial statements include all adjustments, consisting
of only normal recurring adjustments, considered necessary for a fair
presentation of the results of interim periods. Operating results for the
six-month period ended March 31, 1997 are not necessarily indicative of the
results that may be expected for the year ended September 30, 1997.
    
 
2. ACQUISITIONS
 
   
During fiscal 1996, the Company completed the acquisition of three companies
that design and produce water and wastewater treatment systems. Mass Transfer
Systems, Inc. was purchased effective January 31, 1996 for

approximately $7,600,000, consisting of $3,100,000 in cash, $4,100,000 in seller
notes and $400,000 of assumed debt. Aero-Mod, Inc. and Affiliates was purchased
effective April 26, 1996 for approximately $2,400,000, consisting of $1,000,000
in cash, $700,000 in seller notes and $700,000 in assumed debt. Water Equipment
Technologies, Inc. was purchased effective September 30, 1996 for approximately
$5,300,000, consisting of $2,700,000 in cash and $2,600,000 in Waterlink Common
Stock (611,784 shares valued at $4.25 per share.) The purchase price and related
allocation for Water Equipment Technologies, which was preliminary at September
30,1996, was finalized during the second quarter of 1997. The aggregate purchase
price of the 1996 acquisitions includes approximately $8,600,000 million of
goodwill (Mass Transfer Systems -- $5,200,000; Aero-Mod -- $100,000 and Water
Equipment Technologies -- $3,300,000), which is amortized on a straight-line
basis over 40 years.
    
 
   
During fiscal 1995, the Company acquired SanTech Equipment, Inc. and Great Lakes
Environmental, Inc., which design and produce industrial separation systems,
wastewater pretreatment systems and oil/water separation products. SanTech
Equipment was purchased effective March 31, 1995 for cash of approximately
$800,000. Great Lakes Environmental was purchased effective August 31, 1995 for
approximately $8,500,000, consisting of $5,800,000 of cash, $2,200,000 of seller
obligations and $500,000 in Waterlink Common Stock (250,000 shares at $2.00 per
share). The purchase price of the Great Lakes acquisition includes approximately
$7,800,000 million of goodwill, which is amortized on a straight-line basis over
40 years.
    
 
Under the terms of the Mass Transfer Systems, Inc. and Aero-Mod, Inc. and
Affiliates purchase agreements, the Company may be required to make additional
payments of up to $800,000 contingent upon the achievement of certain operating
results through September 30, 1997. In addition, the Water Equipment
Technologies agreement provides for payment of contingent consideration at
September 30, 1997 and 1998 if certain specified targets are achieved. Any such
increases to the purchase price of the acquired companies will be recorded as
additional goodwill.
 
   
On March 5, 1997, the Company acquired the Nordic Water Products Group for
approximately $12,100,000, consisting of $11,100,000 in cash and $1,000,000 of
seller notes. The purchase price includes approximately $4,100,000 of goodwill,
which will be amortized on a straight-line basis over 40 years. The purchase
price allocation has been based on preliminary estimates, which may be revised
at a later date. Further, in conjunction with its planned initial public
offering expected to be completed during the third quarter of fiscal 1997, the
Company anticipates acquiring two additional businesses, Bioclear Technology,
Inc. and Lanco Environmental Products, Inc. The combined purchase price of these
pending acquisitions is expected to total approximately $20,400,000, consisting
of $16,800,000 in cash and 328,270 shares of the Company's Common Stock
aggregating $3,600,000 (assuming an estimated initial public offering price of
$11.00 per share.)
    
 
These acquisitions were accounted for as purchases. The consolidated statement
of operations of the Company includes the results of operations of the acquired
businesses for the period subsequent to the effective date of these
acquisitions.

No interest was paid by the Company in 1995. In 1996, interest paid approximated
$631,000.
    
 
   
On February 19, 1997, the Company entered into a long-term credit facility with
a bank to refinance the obligations due to its existing senior bank leaders
which were due to mature on March 31, 1997. As such, $4,667,000 at September 30,
1996 was classified as long-term debt.
    
 
The new credit facility ("Credit Facility") provides the Company with a
revolving line-of-credit of up to $8,000,000 and a term loan of $11,000,000. The
revolving line-of-credit has a sublimit of $6,000,000 for letters of credit and
can be used for working capital and other general corporate purposes. Loans
under the Credit Facility bear interest at a designated variable base rate plus
spreads ranging from zero to 50 basis points and 25 to 75 basis points,
respectively, depending on the ratio of total consolidated indebtedness to its
earnings before interest, taxes, depreciation and amortization. At the Company's
option, the loans under the Credit Facility may bear interest based on a
designated London interbank offering rate plus spreads ranging from 175 to 225
basis points and 200 to 250 basis points, respectively, based on the same ratio.
The revolving line-of-credit terminates in February 2000, and the term loan
matures in February 2002. The term loan has mandatory

quarterly repayments commencing June 30, 1997 in amounts ranging from $400,000
to $750,000 per repayment. The Credit Facility prohibits or restricts the
Company from many actions, including paying dividends and incurring or assuming
other indebtedness or liens.
 
Obligations under the Credit Facility are secured by substantially all of the
Company's assets, including equipment, inventory, accounts receivable and
general intangibles and a pledge of most of the stock of the Company's
subsidiaries.
 
As part of the Credit Facility, two of the foreign subsidiaries of the Company
have separate facilities of $2,000,000 and $3,800,000, respectively, for
borrowings in local currencies. Each separate facility is guaranteed by the
Company. Both of these facilities mature in February 2000, with outstanding
amounts bearing interest based on a designated London interbank offering rate
plus a spread of 250 basis points.
 
   
As additional consideration for the Credit Facility, the Company entered into a
warrant agreement dated February 19, 1997, (the "Bank Warrant Agreement")
pursuant to which the Bank has been granted a warrant, expiring in 2002, to
purchase 225,000 shares of Common Stock at a purchase price of $4.50 per share.
The aggregate fair value of the 225,000 warrants issued of $265,500 ($1.18 per
warrant) will be treated as an original issue discount and amortized on a
straight-line basis through interest expense over the life of the Credit
Facility.
    
 
   
Additionally, in March 1997, the Company entered into a note purchase agreement
(the "Note Purchase Agreement") pursuant to which the Company may issue, and
several purchasers have committed to purchase, five year subordinated notes in
the principal amount of up to $10,000,000 (the "1997 Notes"). The 1997 Notes
will be issued in $1,000,000 increments at the discretion of the Company. The
obligation of purchasers to purchase the 1997 Notes expires on December 31, 1997
(or earlier in the event of a prepayment event). As of March 5, 1997, no amounts
are outstanding under the 1997 Notes. In addition, purchasers of the 1997 Notes
have been granted warrants to purchase 125,000 shares of the Company's Common
Stock at a purchase price of $4.50 per share. The aggregate fair value of the
125,000 warrants issued of $147,000 ($1.18 per warrant) will be capitalized as
deferred financing costs and amortized on a straight-line basis over the life of
the Note Purchase Agreement. Under the Note Purchase Agreement, warrants will be
granted for each $1,000,000 Note issued to purchase 30,000 shares of the
Company's Common Stock at a purchase price of $4.50 per share. The fair value of
any additional warrants will be determined at the date of issuance and will be
treated as an original issue discount, amortized on a straight-line basis
through interest expense over the life of the Note.
    
 
Future maturities of long-term obligations, giving effect to this refinancing,
for the five years subsequent to September 30, 1996 are as follows:
1997 -- $1,969,000; 1998 -- $2,108,000; 1999 -- $2,851,000; 2000 -- $1,217,000
and 2001 -- $1,600,000.
 
The $400,000 of convertible notes were converted into 100,000 shares of common
stock in October 1996 and the $2,000,000 of convertible notes were converted
into 500,000 shares of common stock in January 1997.
 
6. LEASES
 
The Company leases certain facilities and equipment under operating leases, some
of which are with an entity controlled by related parties. The Company believes
that the rents due under the related party leases are comparable to those which
would be charged by an unrelated party. Rent expense totaled $64,000 in 1995 and

7. REDEEMABLE PREFERRED STOCK
 
Preferred stock consists of 400,000 shares of Series A Preferred Stock (issued
in fiscal 1995), 1,700,000 shares of Series B Preferred Stock (issued in fiscal
1995) and 1,150,000 shares of Series C Preferred Stock (issued in fiscal 1996).
These shares have a par value of $.001 per share and a base liquidation price of
$1.25 per share for Series A Preferred Shares, $2.00 per share for Series B
Preferred Shares, and $4.00 per share for Series C Preferred Shares.
 
Holders of Preferred Stock may, at their option, convert their shares into
Common Stock on a one-for-one basis. Such conversion is required if the Company
consummates an underwritten public offering of Common Stock at a price of at
least $6 a share and gross proceeds to the Company exceed $10 million. The
holders of Preferred Shares are entitled to the number of votes equal to the
number of Common Shares into which the Preferred Shares could be converted.
 
Dividends begin to accrue on the third anniversary of original issuance, which
is December 9, 1997 for Series A Preferred Stock, September 15, 1998 for Series
B Preferred Stock and June 27, 1999 for Series C Preferred Stock. Dividends
accrue at a rate of 8% per annum, payable in either additional Preferred Shares
or cash, at the option of the individual holder. All accrued and unpaid
dividends shall become payable upon conversion into Common Stock; repurchase or
redemption of the Preferred Shares by the Company or the liquidation or winding
up of affairs of the Company.
 
The majority of the holders of all series of Preferred Stock, treated as a
single class, may require the Company to redeem the outstanding Preferred Shares
in the case of a consolidation or merger in which the Company is not the
surviving corporation. The Company may redeem the Preferred Shares at anytime
with the consent of shareholders owning at least 60% of the outstanding
Preferred Shares.

9. STOCK COMPENSATION PLANS
 
During 1995, the Board of Directors approved the Waterlink, Inc. 1995 Stock
Option Plan which provides for the granting of stock options to key employees
for the purchase of shares of the Company's Common Stock. The maximum aggregate
number of shares to which options may be granted under the Plan was increased
from 800,000 shares to 1,300,000 shares in December 1996. The number of stock
options granted and the purchase price thereof is determined by the Compensation
Committee of the Board of Directors.

The Company has reserved 5,273,000 shares of Common Stock for possible
conversion of the convertible subordinated notes described in Note 5, the
possible conversion of the Preferred Shares described in Note 7 and the exercise
of outstanding stock options.
 
   
A special charge to operations of approximately $2.6 million ($0.13 per share,
after tax), assuming an initial public offering price of $11.00 per share, will
be incurred in the quarter in which the Offering is completed. Such charge
results primarily from the issuance upon completion of the Offering by the
Company of a ten year option to purchase 100,000 shares of Common Stock at a
price of $.10 per share to an officer of the Company pursuant to the terms of an
employment agreement. Of this amount, approximately $1.1 million is non-cash,
and approximately $1.5 million represents cash payments related principally to
the reimbursement of income taxes resulting from this stock option issuance.

To the Board of Directors of
GREAT LAKES ENVIRONMENTAL, INC.
 
     We have audited the accompanying balance sheets of GREAT LAKES
ENVIRONMENTAL, INC. as of December 31, 1994 and August 31, 1995 and the related
statements of income, shareholders' equity and cash flows for the year ended
December 31, 1994 and the eight months ended August 31, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of GREAT LAKES ENVIRONMENTAL,
INC. at December 31, 1994 and August 31, 1995 and the results of its operations
and its cash flows for the year ended December 31, 1994 and the eight months
ended August 31, 1995, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
 
                                AUGUST 31, 1995
 
1.   DESCRIPTION OF BUSINESS AND ORGANIZATION
 
Great Lakes Environmental, Inc. (the "Company"), located in Addison, Illinois,
operates in a single business segment designing oil/water separation equipment
and systems. The Company's products are used by industrial customers primarily
in the manufacturing, food processing and refinery/petrochemical sectors.
 
Effective January 1, 1989, the Company elected, by unanimous consent of its
shareholders, to be taxed under the provisions of Subchapter S of the Internal
Revenue Code. Under these provisions, the Company does not pay federal corporate
income taxes on its income. Instead, the shareholders are liable for individual
federal income taxes on their respective shares of the Company's income. This
election was terminated as a result of the business combination with Waterlink,
Inc. described below.
 
On August 31, 1995, Waterlink, Inc. purchased certain assets and assumed certain
liabilities of Great Lakes Environmental, Inc.
 
2.   ACCOUNTING POLICIES
 
CASH EQUIVALENTS
 
The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
REVENUE RECOGNITION
 
Sales are recognized when products are shipped.
 
INVENTORIES
 
Inventories are valued at the lower of cost or market. Cost is determined using
the first-in, first-out (FIFO) method.
 
EQUIPMENT
 
Property and equipment is recorded at cost. Expenditures for repairs and
maintenance are charged to operations as incurred, while expenditures for
additions and improvements are capitalized. Depreciation is computed principally
using the accelerated methods based on the estimated useful lives of the assets,
which range from 3 to 7 years.
 
EMPLOYEE RETIREMENT PLAN
 
The Company sponsors a profit-sharing plan which covers substantially all
employees with more than one full year of service. The Company's contributions
to the plan are at the discretion of the Board of Directors. The amount charged
to operations relating to the plan was $100,000 for the year ended December 31,
1994 and $60,000 for the eight months ended August 31, 1995.
 
FINANCIAL INSTRUMENTS
 
The carrying value of cash, cash equivalents, accounts receivable and accounts
payable are a reasonable estimate of their fair value due to the short-term
nature of these instruments.
 
Financial instruments which potentially subject the Company to concentrations of
credit risk consist principally of cash equivalents and trade receivables. The
Company maintains its cash in bank deposit

2.   ACCOUNTING POLICIES (CONTINUED)
accounts which, at times, exceed federally insured limits. The Company has not
experienced any losses in such accounts. Management believes it is not exposed
to any significant credit risk on cash and cash equivalents.
 
Concentrations of credit risk with respect to trade receivables are limited by
the Company collecting customer deposits in conjunction with larger contracts.
The Company grants credit to customers based on an evaluation of their financial
condition and collateral is generally not required. Losses from credit sales are
provided for in the financial statements and have been within management's
expectations.
 
USE OF ESTIMATES
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.
 
RECLASSIFICATIONS
 
Certain items in the 1994 financial statements have been reclassified to agree
with the 1995 classifications.

4.   NOTES RECEIVABLE--SHAREHOLDERS
 
The notes receivable--shareholders represents demand notes due from two
shareholders in connection with the purchase and retirement of shares of the
Company's common stock. The notes bear interest, which is paid monthly, at a
variable rate (5.88% at August 31, 1995).
 
5.   LEASES
 
As part of the business combination with Waterlink, Inc., the Company entered
into a five year lease agreement with the former majority shareholder for its
principal office, warehouse and production facility in Addison, Illinois. Prior
to this time, the Company leased these facilities from the shareholder on a
month-to-month basis. The Company believes that the rents due under the related
party lease agreement are comparable to those which would be charged by an
unrelated party. Rent expense totaled $44,400 for the year ended December 31,
1994 and $29,600 for the eight months ended August 31, 1995.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Mass Transfer Systems, Inc.
 
     We have audited the accompanying balance sheets of Mass Transfer Systems,
Inc. as of December 31, 1994, December 31, 1995 and January 31, 1996 and the
related statements of operations, shareholders' equity and cash flows for the
year ended February 28, 1994, ten month period ended December 31, 1994, year
ended December 31, 1995 and the month ended January 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Mass Transfer Systems, Inc.
at December 31, 1994, December 31, 1995 and January 31, 1996 and the results of
its operations and its cash flows for the year ended February 28, 1994, ten
month period ended December 31, 1994, year ended December 31, 1995 and the month
ended January 31, 1996 in conformity with generally accepted accounting

                         NOTES TO FINANCIAL STATEMENTS
 
                                JANUARY 31, 1996
 
1.   DESCRIPTION OF BUSINESS AND ORGANIZATION
 
Mass Transfer Systems, Inc. (the "Company"), located in Fall River,
Massachusetts, operates in a single business segment, designing customized jet
aeration systems to introduce oxygen into a wastewater stream in order to
accelerate the biological digestion process. The Company's products are used by
industrial and municipal customers worldwide to increase the efficiency of
processing waste water, with sales primarily in the United States, the United
Kingdom and Canada. Export sales represented approximately two-thirds of total
sales for all periods presented.
 
Effective March 1, 1987, the Company elected, by unanimous consent of its
shareholders, to be taxed under the provisions of Subchapter S of the Internal
Revenue Code. Under these provisions, the Company does not pay federal corporate
income taxes on its income. Instead, the shareholders are liable for individual
federal income taxes on their respective shares of the Company's income. This
election was terminated as a result of the business combination with Waterlink,
Inc. described below.
 
At the close of business on January 31, 1996, Waterlink, Inc. purchased
substantially all of the assets and assumed certain liabilities of the Company.
 
2.   ACCOUNTING POLICIES
 
PERIODS INCLUDED IN FINANCIAL STATEMENTS
 
The Company changed its year end in 1994 from February 28 to December 31. In
addition, the accompanying financial statements include the one month period in
1996 prior to the business combination with Waterlink, Inc. Reference to these
various periods in the notes to the financial statements are: 1996--the one
month ended January 31, 1996; 1995--the year ended December 31, 1995; 1994--the
ten months ended December 31, 1994; and 1993--the year ended February 28, 1994.
 
CASH EQUIVALENTS
 
The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
REVENUE RECOGNITION
 
Sales are recognized when products are shipped.
 
ACCOUNTS RECEIVABLE
 
Accounts receivable include retainage which has been billed, but is not due
pursuant to retainage provisions in construction contracts until completion of
performance and acceptance by the customer. This retainage aggregated $360,000,
$360,000 and $349,000 at December 31, 1994, December 31, 1995 and January 31,
1996, respectively. Substantially all retained balances are collected within one
year.
 
INVENTORIES
 
Inventories are valued at the lower of cost or market. Cost is determined using
the first-in, first-out (FIFO) method.

                                JANUARY 31, 1996
 
2.   ACCOUNTING POLICIES (CONTINUED)

PROPERTY, PLANT AND EQUIPMENT
 
Property, plant and equipment is recorded at cost. Expenditures for repairs and
maintenance are charged to operations as incurred, while expenditures for
additions and improvements are capitalized. Depreciation is computed principally
using the straight-line method over the estimated useful lives of the assets.
The useful lives range from 15 to 31 years for buildings and improvements; 5 to
10 years for machinery and equipment and 3 to 10 years for furniture and
fixtures.
 
INTANGIBLE ASSET
 
The intangible asset is a covenant-not-to-compete contract with a former
shareholder and is carried at cost. Amortization is recorded using the
straight-line method over the life of the contract of three years.
 
FOREIGN CURRENCY TRANSLATION
 
Some transactions of the Company are made in currencies different from its own.
Gains and losses from these transactions are included in income as they occur.
Net foreign currency transaction gains and (losses) included in income before
taxes totaled ($18,000) in 1993, ($15,000) in 1994, $54,000 in 1995 and
($20,000) in 1996.
 
USE OF ESTIMATES
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.
 
3.   INVENTORIES
 
Inventories were as follows:

The note payable-shareholder represents a promissory note due to the majority
shareholder for unpaid distributions. Through January 31, 1996, the note was
unsecured and due on demand. The terms of the note were revised to provide a due
date of February 1, 2001 in connection with the business combination with
Waterlink, Inc. Accordingly, the note was reclassified to long-term obligations
for all periods presented. Interest expense on the note payable-shareholder was
as follows: 1994--$90,900; 1995--$103,600 and 1996--$10,000.
 
The non-compete agreement between the Company and a previous minority
shareholder provides for semi-annual installments on June 30 and December 31 of
each year over a three year period.
 
Approximate future maturities of long-term debt obligations for the five years
subsequent to January 31, 1996 are as follows: 1997--$112,000; 1998--$50,000;
1999--$51,000; 2000--$-0-and 2001--$1,200,000.
 
Interest expense approximates interest paid for all periods presented.

6.   FINANCIAL INSTRUMENTS
 
The carrying value of cash, cash equivalents, accounts receivable and accounts
payable are a reasonable estimate of their fair value due to the short-term
nature of these instruments. The Company's long-term debt, except for notes
payable to related parties, has a variable rate and cost approximates fair value
at January 31, 1996. The notes payable to related parties do not have a ready
market and cost is assumed to approximate fair value.
 
Financial instruments which potentially subject the Company to concentrations of
credit risk consist principally of cash equivalents and trade receivables. The
Company maintains its cash in bank deposit accounts which, at times, exceed
federally insured limits. The Company has not experienced any losses in such
accounts. Management believes it is not exposed to any significant credit risk
on cash and cash equivalents.
 
Concentrations of credit risk with respect to trade receivables are limited by
the Company collecting customer deposits in conjunction with larger contracts.
The Company grants credit to customers based on an evaluation of their financial
condition and collateral is generally not required. Losses from credit sales are
provided for in the financial statements and have been within management's
expectations.
 
The Company issues letters of credit as guarantees for various performance
obligations. Under the terms of these letters of credit, approximately $143,000
and $140,000 of cash was restricted at December 31, 1995 and January 31, 1996,
respectively. The letters of credit outstanding at January 31, 1996 are
scheduled to expire at various times through June of 1997.
 
The Company periodically enters into foreign exchange contracts to hedge certain
operational exposures against changes in foreign currency exchange rates.
Because the impact of movements in currency exchange rates on foreign exchange
contracts offsets the related impact on the underlying items being hedged, these
instruments do not subject the Company to risk that would not otherwise result
from changes in currency exchange rates. At December 31, 1995 and January 31,
1996, the Company had a foreign exchange contract outstanding which exchanged
U.S. dollars for Canadian dollars. The contract, which matured in February 1996,
had a notional amount of approximately $150,000 and an unrealized gain of $3,000
at January 31, 1996.
 
7.   CONTINGENCIES
 
The Company is involved in certain legal actions arising in the ordinary course
of business. In the opinion of management, such litigation and claims will be
resolved without a material effect on the Company's financial position, cash
flows or results of operations.

To the Board of Directors
Aero-Mod, Inc, and Affiliates
 
     I have audited the accompanying combined balance sheets of Aero-Mod, Inc.
and Affiliates as of October 31, 1994, October 31, 1995, and April 26, 1996 and
the related combined statements of income, retained earnings, and cash flows for
the years ended October 31, 1994 and 1995; and the period beginning November 1,
1995 and ended April 26, 1996. These financial statements are the responsibility
of the companies' management. My responsibility is to express an opinion on
these financial statements based on my audits.
 
     I conducted my audits in accordance with generally accepted auditing
standards. Those standards require that I plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
I believe that my audits provide a reasonable basis for my opinion.
 
     In my opinion, the financial statements referred to in the first paragraph
present fairly, in all material respects, the financial position of Aero-Mod,
Inc. and Affiliates at October 31, 1994, October 31, 1995, and April 26, 1996,
and the results of operations and cash flows on a combined basis for the periods
then ended in conformity with generally accepted accounting principles.

NOTE B--SIGNIFICANT ACCOUNTING POLICIES
 
This summary of significant accounting policies is presented to assist in
understanding the companies' financial statements. These accounting policies
conform to generally accepted accounting principles and have been consistently
applied in preparation of the financial statements.
 
1.   OPERATING CYCLE
 
Assets and liabilities related to contracts are included as current assets and
current liabilities on the accompanying balance sheets, as they will normally be
completed within the following fiscal year.
 
2.   FINANCIAL STATEMENT PERIODS
 
The periods reported on these financial statements are the years ended October
31, 1994, and October 31, 1995 and the period beginning November 1, 1995 and
ended April 26, 1996 (referred to as "the period ended April 26, 1996"
throughout).
 
3.   REVENUE AND COST RECOGNITION
 
Revenues from construction contracts are recognized on the
percentage-of-completion method, measured by contract costs incurred to date by
phase in relation to total estimated contract costs when contracts have
progressed sufficiently to allow for estimation.
 
Contract costs include all direct material, labor, subcontracts and those
indirect costs related to contract performance, such as gas, oil supplies,
travel, equipment rent and allocations of indirect construction costs.
 
Estimated losses on contracts in progress are recorded in the period such losses
are determined. Changes in job performance, job conditions, estimated
profitability and final contract settlement may result in revisions to costs and
income and are recognized when determined.
 
The asset "Costs and estimated earnings in excess of billings on uncompleted
contracts", represents revenues recognized in excess of amounts billed. The
liability, "Billings in excess of costs and estimated earnings on uncompleted
contracts", represents billings in excess of revenues received.
 
4.   INVENTORY
 
Inventory is generally stated at the lower of cost (first-in, first-out method)
or market. Capitalized Section 263A costs are as follows:

5.   FIXED ASSETS
 
Fixed assets are stated at cost. Major improvements and betterments to existing
fixed assets have been capitalized. Expenditures for maintenance and repairs
which do not extend the life of the applicable assets have been charged to
expense as incurred.
 
Depreciation is provided principally by the straight-line and accelerated
methods over the estimated useful lives of the assets, which are generally five
to ten years (10 to 40 years for leasehold improvements).
 
6.   AMORTIZATION OF INTANGIBLES
 
The cost of patents acquired are being amortized on the straight-line method
over 17 years.
 
7.   INCOME TAX EXPENSE (BENEFIT)
 
Resi-Tech, Inc. (except for FYE October 31, 1994) and Blue Water Services, Inc.
are subchapter S corporations, and, therefore, do not pay income tax at the
corporate level. The companies' corporate income tax expense (benefit) is as
follows:

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
                                 APRIL 26, 1996
 
NOTE B--SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Contracts in progress are reported for financial statement purposes using the
percentage-of-completion method whereas for tax reporting purposes, the
completed contract method of accounting is utilized.
 
On April 26, 1996, the companies had state income tax credits in the amount of
$11,990 to carryforward.
 
8.   CASH SURRENDER VALUE OF LIFE INSURANCE
 
The companies and stockholder's spouse are beneficiaries of insurance policies
on the life of the 100% stockholder.
 
9.   USE OF ESTIMATES
 
The preparation of financial statements under generally accepted accounting
principles requires management to make estimates and assumptions that affect
certain reported amounts and disclosures. Accordingly, actual results could
differ from those estimates.
 
10. ALLOWANCE FOR DOUBTFUL ACCOUNTS
 
The companies have elected to use the direct write-off method to account for bad
debts. This is not in conformity with generally accepted accounting principles;
however, the difference is not considered material.

NOTE I--SIMPLIFIED EMPLOYEE PENSION PLAN
 
The companies sponsor a simplified employee pension plan for qualifying
employees in which discretionary contributions are made to eligible
participant's individual IRA account. Contributions are based on a percentage of
each covered employee's salary. For the years ended October 31, 1994 and October
31, 1995, a 5.0% contribution had been made. For the period beginning November
1, 1995 and ended April 26, 1996, no decision had been made relating to pension
contributions.
 
NOTE J--MAJOR CUSTOMERS AND RISK CONCENTRATIONS
 
The companies currently grant credit to its customers. Management believes that
its contract acceptance, billing, and collection policies are adequate to
minimize potential credit risk. The companies conduct a large portion of their
business with large corporations and various municipalities. The stability of
these entities should also minimize potential credit risk.

NOTE L--CONTINGENCY/FOREIGN CURRENCY CONTRACTS
 
Aero-Mod, Inc. was engaged in one foreign contract stated in terms of foreign
currency. The fluctuation of the exchange rates between the foreign currency and
the U.S. dollar resulted in a foreign currency transaction loss in the amount of
$49,867, which is reflected in gross sales for the period ended April 26, 1996.
Since the amount of gain or loss relating to this contract could not be
reasonably estimated as of October 31, 1995, no adjustment was made to the
books. The contract price, however, was adjusted to reflect the October 31, 1995
exchange rate when calculating percentage-of-completion amounts for
work-in-progress.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Water Equipment Technologies, Inc.
 
     We have audited the accompanying consolidated balance sheets of Water
Equipment Technologies, Inc. and subsidiary as of September 30, 1995 and 1996,
and the related consolidated statements of operations, shareholders' equity and
cash flows for each of the three years in the period ended September 30, 1996.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Water Equipment Technologies, Inc. and subsidiary at September 30, 1995 and
1996, and the consolidated results of their operations and their cash flows for
each of the three years in the period ended September 30, 1996, in conformity
with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               SEPTEMBER 30, 1996
 
1. DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION
 
Water Equipment Technologies, Inc. (the "Company"), located in West Palm Beach,
Florida, operates in a single business segment designing and building water
treatment filters and reverse osmosis systems and related equipment. The
Company's products are used worldwide by industrial, municipal and residential
customers, with sales primarily in the United States, United Kingdom, Middle
East and Pacific Rim. Export sales represented approximately one-third of total
sales for all periods presented.
 
At the close of business on September 30, 1996, the Company merged with
Waterlink, Inc. in a transaction in which the Company exchanged all of its
common stock for a combination of cash and shares of common stock in Waterlink,
Inc. Immediately prior to the merger transaction, the Company's wholly-owned
subsidiary, Ultra Pure Water, was spun-off in the form of a dividend to the
shareholders' of the Company. The accompanying financial statements include only
the accounts and operations of Water Equipment Technologies, Inc. and its
wholly-owned subsidiary, Water Equipment Technologies (Europe) Limited, which
were acquired by Waterlink, Inc. on September 30, 1996 as described above. Water
Equipment Technologies (Europe) Limited become inactive on December 31, 1994.
All significant intercompany balances and transactions have been eliminated.
 
2. ACCOUNTING POLICIES
 
CASH EQUIVALENTS
 
The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.
 
REVENUE RECOGNITION
 
The principal business of the Company is to design and produce water and
wastewater treatment systems, the majority of which are custom designed and take
a number of months to complete. Revenue for significant contracts is recognized
using the percentage-of-completion method of accounting in the proportion that
costs bear to total estimated costs at completion. Revisions of estimates to
complete and losses, if any, are recognized in the period in which they are
determined. Sales of membrane filters in the residential market are recognized
when shipped.
 
FINANCIAL INSTRUMENTS
 
The carrying value of cash, cash equivalents, accounts receivable and accounts
payable are a reasonable estimate of their fair value due to the short-term
nature of these instruments.
 
CONCENTRATIONS OF CREDIT RISK
 
Concentrations of credit risk with respect to trade receivables are limited due
to the Company's credit policy which generally requires deposits at signing of
the contract and letters of credit for all customers outside the United States.
The Company grants credit to domestic customers based on an evaluation of their
financial condition and collateral is generally not required. Losses from credit
sales are provided for in the financial statements and have historically been
within management's expectations.

2. ACCOUNTING POLICIES (CONTINUED)
INVENTORIES
 
Inventories are valued at the lower of cost or market. Cost is determined using
the first-in, first-out (FIFO) method.
 
PROPERTY, PLANT AND EQUIPMENT
 
Property, plant and equipment is valued at cost. Expenditures for repairs and
maintenance are charged to operations as incurred, while expenditures for
additions and improvements are capitalized. Depreciation is computed principally
using the declining-balance and straight-line methods over the estimated useful
lives of assets. The useful lives are 5 years for leasehold improvements; 5 to 7
years for machinery and equipment and 7 years for furniture and fixtures.
 
USE OF ESTIMATES
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.
 
3. INVENTORIES
 
Inventories were as follows:

Management has determined, based on the Company's history of prior earnings,
that operating results of the Company will more likely than not be sufficient to
recognize fully the net deferred tax asset. Accordingly, no valuation allowance
for deferred tax assets is required.
 
10. CONTINGENCIES
 
The Company is involved in certain legal actions arising in the ordinary course
of business. In the opinion of management, such litigation and claims will be
resolved without a material effect on the Company's financial position, cash
flows or results of operations.

                         REPORT OF INDEPENDENT AUDITORS
 
Board of Directors
Nordic Water Products Group
 
   
     We have audited the accompanying combined balance sheets of the Nordic
Water Products Group as of March 31, 1996 and February 28, 1997, and the related
combined statement of operations, shareholders' equity and cash flows for each
of the two years in the period ended March 31, 1996, and for the eleven months
ended February 28, 1997. These financial statements, which are expressed in
Swedish Kronor, are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
    
 
   
     We conducted our audits in accordance with generally accepted auditing
standards in Sweden which, in all material respects, conform to generally
accepted auditing standards in the United States. Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.
    
 
   
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the combined financial position of the Nordic Water
Products Group at March 31, 1996, and February 28, 1997, and the combined
results of their operations and their cash flows for the two years in the period
ended March 31, 1996, and for the eleven months ended February 28, 1997 in
conformity with generally accepted accounting principles in Sweden.
    
 
   
     Generally accepted accounting principles in Sweden vary in certain respects
from generally accepted accounting principles in the United States. Application
of generally accepted accounting principles in the United States would have
affected net income for each of the two years in the period ended March 31, 1996
and for the eleven months ended February 28, 1997, and shareholders' equity as
of March 31, 1996 and February 28, 1997, to the extent summarized in Note 13, to
the combined financial statements.

1. DESCRIPTION OF BUSINESS AND ORGANIZATION
 
The Nordic Water Products Group of companies (the "Group") operates in a single
business segment, designing and producing water and waste water treatment
equipment used by industrial and municipal customers. The Group's sales are made
predominately in Europe, with a concentration in the Scandinavian countries and
Germany.
 
The combined financial statements include the financial statements of the
companies purchased by Waterlink, Inc. in a transaction which was consummated on
March 5, 1997. During the periods included in these financial statements there
was no single holding company for the Group, with the companies all ultimately
owned by Anglian Water International ("Anglian"). The companies which comprise
the Nordic Water Products Group are as follows:

2. BASIS OF PRESENTATION
 
The accompanying combined financial statements have been prepared in accordance
with Swedish generally accepted accounting principles for the purpose of
complying with the rules and regulations of the Securities and Exchange
Commission located in the United States of America. A reconciliation of net
income and shareholders' equity between Swedish GAAP and U.S. GAAP is performed
in Note 13.
 
   
The figures presented in these financial statements have been prepared by
combining the historical results of the entities listed in Note 1, except for
the provision of income taxes discussed below. All inter-group transactions and
balances have been eliminated on combination.
    
 
3. ACCOUNTING POLICIES
 
REVENUE RECOGNITION
 
Sales are primarily recorded when products are shipped. Revenues for contracts
are recognized using the completed-contract method of accounting.
 
FISCAL YEAR END
 
   
The Group's fiscal year ends on March 31. References in the footnotes to the
years 1995 and 1996 refer to the fiscal years ended March 31, 1995, and 1996,
respectively. For accounting purposes, the Group was assumed to be acquired on
March 1, 1997. References in the footnotes to the year 1997 refers to the eleven
months ended February 28, 1997.
    
 
CASH EQUIVALENTS
 
The Group considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.

                               FEBRUARY 28, 1997
    
 
   
3. ACCOUNTING POLICIES (CONTINUED)
    
CONCENTRATIONS OF CREDIT RISK
 
Financial instruments which potentially subject the Group to concentrations of
credit risk consist principally of cash equivalents and trade receivables. The
Group places its cash equivalents with high quality financial institutions.
 
Concentrations of credit risk with respect to trade receivables are limited due
to the Group's large number of customers and their dispersion across many
different regions and industries. The Group grants credit to customers based on
an evaluation of their financial condition and collateral is generally not
required. Losses from credit sales are provided for in the financial statements
and have been within management's expectations.
 
FINANCIAL INSTRUMENTS
 
The carrying value of cash, cash equivalents, accounts receivable and accounts
payable are a reasonable estimate of their fair value due to the short-term
nature of these instruments. The notes payable -- related party do not have a
ready market and cost is assumed to approximate fair value.
 
INVENTORIES
 
Inventories are valued at the lower of cost or market. Cost is determined using
the average cost method.
 
AMORTIZATION OF INTANGIBLE ASSETS
 
Intangible assets consist primarily of goodwill which is amortized on a
straight-line basis over ten years.
 
PROPERTY, PLANT AND EQUIPMENT
 
Property, plant and equipment is valued at cost. Expenditures for repairs and
maintenance are charged to operations as incurred, while expenditures for
additions and improvements are capitalized. Depreciation is computed principally
using the straight-line method over the estimated useful lives of assets. The
useful lives range from 16 to 50 years for building and improvements; 5 to 10
years for machinery, equipment and furniture.
 
INCOME TAXES
 
   
On a historical basis, the taxable income of certain companies in the Group was
included in the tax return of the Anglian tax paying group of which it was a
part. The provision for income taxes in these financial statements was
calculated on a standalone basis for all companies using the appropriate enacted
tax rate for each country. The deferred tax provision was provided for temporary
differences between the financial reporting basis and the statutory tax basis of
the Group's assets and liabilities.
    
 
RESEARCH AND DEVELOPMENT
 
   
Research and development costs are charged to expense as incurred and amounted
to KSEK 6,293 in 1995, KSEK 5,152 in 1996 and KSEK 5,531 in 1997.
    
 
FOREIGN CURRENCY TRANSLATION
 
Local currencies of the countries indicated in Note 1 above are considered the
functional currencies of the companies included in the combined financial
statements. Assets and liabilities are translated at the rate of

exchange in effect on the balance sheet dates, while income and expense items
are translated at average rates of exchange prevailing during the applicable
period. The related translation adjustments are reflected in shareholder's
equity. Foreign currency exchange gains or (losses) recorded in the statement of
operations were KSEK (94) in 1995, KSEK 701 in 1996 and KSEK (183) in 1997.
    
 
USE OF ESTIMATES
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.
 
   
4. ACCOUNTS RECEIVABLE
    
 
   
Accounts receivable are stated net of allowances for doubtful accounts of KSEK
762 at March 31, 1996 and KSEK 520 at February 28, 1997.

As of February 28, 1997, the Group has deferred tax assets attributable to
operating loss carryforwards and other temporary differences in Germany.

uncertain and a valuation allowance has been recorded. For statutory tax
purposes, the foreign operating loss carryforwards amounted to KSEK 15,878 at
February 28, 1997 and have an indefinite expiration period.
    
 
12. CONTINGENCIES
 
The Group is involved in certain legal actions arising in the ordinary course of
business. In the opinion of management, such litigation and claims will be
resolved without a material effect on the Group's financial position, cash flows
or results of operations.

13. GENERALLY ACCEPTED ACCOUNTING PRINCIPLES IN THE UNITED STATES (CONTINUED)
    
The application of U.S. GAAP would not have significantly affected the other
reported balance sheet items in the combined balance sheet.
 
Accounting for Contracts
 
Under U.S. GAAP, income from significant contracts is permitted to be recognized
using the percentage-of-completion method of accounting in the proportion that
costs bear to total estimated costs at completion. Under Swedish GAAP, income is
generally recorded using the completed contract method. This adjustment was made
to conform to Waterlink's policy of using the percentage-of-completion method.
 
Restricted Reserves and Retained Earnings
 
Under Swedish law, restricted reserves are not available for distribution but
are required to be held to meet statutory requirements. Translation gain or loss
on conversion of foreign financial statements is included in restricted reserves
and retained earnings, as applicable.
 
Exchange Rate Data
 
   
The following table sets forth at the end of and for the periods indicated,
certain information concerning the closing, average, high and low exchange rates
for United States Dollars ("US$") as a ratio of Swedish Kronor ("SEK"). The
exchange rates used are those quoted by the Federal Reserve Bank of New York and
are the noon buying rates in New York City for cable transfers in foreign
currencies. On April 11, 1997, the closing ratio of United States Dollars per
Swedish Kronor was .130.

                          INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors
Lanco Environmental Products, Inc.
 
     We have audited the accompanying balance sheet of Lanco Environmental
Products, Inc., as of December 31, 1995 and 1996, and the related statements of
income, changes in stockholder's equity and cash flows for the six-month periods
ended June 30, 1995 and December 31, 1995, and the year ended December 31, 1996.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Lanco Environmental
Products, Inc., as of December 31, 1995 and 1996, and the results of its
operations and its cash flows for the six-month periods ended June 30, 1995 and
December 31, 1995, and the year ended December 31, 1996, in conformity with
generally accepted accounting principles.

                           DECEMBER 31, 1995 AND 1996
 
   
              (INFORMATION AS OF MARCH 31, 1997 AND FOR THE THREE
    
   
               MONTHS ENDED MARCH 31, 1996 AND 1997 IS UNAUDITED)
    
 
NOTE 1 -- NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
 
Lanco Environmental Products, Inc., is engaged in manufacturing wastewater
treatment equipment and components. The Company grants credit to customers, the
majority of whom are United States manufacturers.
 
   
Basis of Presentation -- Lanco Environmental Products, Inc., was formed July 1,
1995, when the sole stockholder of Lanco Corporation transferred the assets and
liabilities of Lanco Corporation's Environmental Products Division into a
separate corporation owned by the stockholder. All assets and liabilities were
transferred at their historical carrying amount. These financial statements
present the operations of Lanco Environmental Products, Inc., for the six-month
period from July 1, 1995 to December 31, 1995, and the year ended December 31,
1996. Also presented, for comparative purposes, are statements of income and
cash flows for the Environmental Products Division of Lanco Corporation for the
six-month period January 1, 1995, to June 30, 1995.
    
 
   
The balance sheet as of March 31, 1997, the statement of operations and retained
earnings for the nine months ended March 31, 1996 and 1997 and the statements of
cash flows for the periods then ended are unaudited and reflect all adjustments,
which include, in the opinion of management, adjustments consisting only of
normal recurring adjustments necessary to present fairly the results of
operations for such periods. Results of interim periods are not necessarily
indicative of results to be expected for any other interim period or for the
year taken as a whole.
    
 
Cash Equivalents -- The Company considers all highly liquid investments
purchased with a maturity of three months or less to be cash equivalents.
 
Revenue and Cost Recognition -- Revenue from the sale of wastewater treatment
equipment contracts is generally recognized upon shipment. Contract costs
include all direct material and labor costs and those indirect costs related to
contract performance, such as indirect labor, supplies, repairs and depreciation
costs. Selling and administrative costs are charged to expense as incurred.
 
Financial Instruments -- The carrying values of cash, cash equivalents, accounts
receivable and accounts payable are reasonable estimates of their fair market
values due to the short-term nature of these instruments.
 
Inventories -- Inventories of component parts and finished goods are stated at
the lower of cost, determined by the first-in, first-out method, or market.
 
Leasehold Improvements and Equipment -- Leasehold improvements and equipment are
recorded at cost. Depreciation is computed principally on the straight-line
method over the estimated useful lives of the assets. Costs of maintenance and
repairs are charged to expense when incurred.
 
Income Taxes -- The Company accounts for income taxes following the liability
method. A current tax liability or asset is recognized for the estimated taxes
payable or refundable on tax returns for the year. Deferred tax liabilities or
assets are recognized for the estimated future tax effects of temporary
differences between book and tax accounting.
 
Use of Estimates -- The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
 
     In our opinion, these consolidated financial statements present fairly, in
all material respects, the financial position of the company as at August 31,
1996 and 1995, and the results of its operations and the changes in its
financial position for each of the years in the three-year period ended August
31, 1996 in accordance with accounting principles generally accepted in Canada.

1. SIGNIFICANT ACCOUNTING POLICIES
 
These financial statements have been prepared by management on the historical
cost basis in accordance with accounting principles generally accepted in
Canada. These accounting principles are, in all material respects, in accordance
with those generally accepted in the United States except as described in note
11, "Summary of Significant Differences Between Canadian and U.S. Generally
Accepted Accounting Principles."
 
(a) Principles of consolidation
 
These consolidated financial statements, expressed in Canadian dollars, include
the accounts of the company and its wholly-owned subsidiaries, Bioclear Tech
Sales Inc. and Bioclear Technology U.S.A., Inc.
 
(b) Revenue recognition
 
The company recognizes contract revenue using the "percentage of completion"
method of accounting in the proportion that costs bear to total estimated costs
at completion. Revisions of estimates to complete and losses, if any, are
recognized in the period in which they are determined.
 
(c) Fixed assets
 
Fixed assets are stated at historical cost. Normal maintenance and repairs are
expensed as incurred. Investment tax credits received towards the acquisition of
fixed assets are deducted from fixed assets with depreciation calculated on the
net amount.
 
Depreciation is provided over the estimated life of the asset at the following
annual rates and bases:
 
<TABLE>
<S>                        <C>     <C>
Building                     4%    Declining balance
Furniture and fixtures      20%    Declining balance
Office equipment            20%    Declining balance
Pilot plant                 20%    Declining balance
Shop equipment              20%    Declining balance
Bridge crane                20%    Declining balance
Small tools                 50%    Straight line
Trucks                      30%    Declining balance
</TABLE>
 
When fixed assets are sold or scrapped, the cost of the asset and the related
accumulated depreciation are removed from the accounts and the resulting gain or
loss is included in income.
 
(d) Income taxes
 
The company follows the tax allocation method of providing for income taxes.
Under this method, the provision for income taxes is based upon the income
reported on the income statement.
 
(e) Translation of foreign currencies
 
The financial statements of the U.S. subsidiary, which is considered to be an
integrated foreign operation, and foreign currency denominated balances of the
company have been translated to Canadian dollars using the
 
                                      F-92

temporal method. Under this method, monetary assets and liabilities, both
current and long-term, are translated at year end rates of exchange. Other
assets and liabilities are translated at historical rates of exchange in effect
at the dates of transactions.
 
Revenue and costs are translated at the average rates of exchange for the year
except for property, plant and equipment, depreciation and opening inventory
which are translated at historical rates.
 
Gains and losses on translation are included in income.
 
2. AMALGAMATION
 
The company was formed on August 31, 1996, through the amalgamation of 3212904
Canada Ltd. and Bioclear Technology Inc. Also, Bioclear Technology Inc. was
formed on August 31, 1994 through the amalgamation of 3034321 Canada Ltd.,
Bioclear Technology Inc. and Bioclear Holdings Inc. The financial statements of
the company recognize the continuity of interest of the shareholders in the
assets, liabilities, and operations of the amalgamating companies and are
prepared on the following basis:
 
(a) In the balance sheet, the assets, liabilities, share capital and retained
    earnings of the amalgamating companies have been combined at their
    respective carrying values.
 
(b) The statements of income and retained earnings and cash flows represent the
    combined results of operations and combined cash flows of the amalgamating

    necessarily indicative of the results that may be expected for the year
    ended August 31, 1997.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
    
 
     Section 145 of the DGCL permits the indemnification of the directors and
officers of the Company. The Company Bylaws provide that it will indemnify the
officers, directors, employees and agents of the Company to the extent permitted
by the DGCL.
 
     The Company Certificate provides for the indemnification of directors and
officers of the Company, and persons who serve or served at the request of the
Company as a director, officer, employee or agent of another corporation,
including service with respect to employee benefit plans, against all expense,
liability and loss (including attorneys' fees, judgments, fines, ERISA excise
taxes or penalties in amounts paid or to be paid in settlement) reasonably
incurred with respect to any action, suit or proceeding, whether civil,
criminal, administrative or investigative, provided, however, the Company shall
indemnify any such person seeking indemnification in connection with a
proceeding initiated by such person only if such proceeding was authorized by
the Company's Board. In the event a claim for indemnification by any person has
not been paid in full by the Company after written request has been received by
the Company, the claimant may at any time thereafter bring suit against the
Company to recover the unpaid amount of the claim and, if successful in whole or
in part, the claimant shall be entitled to be paid also the expense of
prosecuting such claim. The right to indemnification conferred in the Company
Certificate is a contract right and shall include the right to be paid by the
Company the expenses incurred in defending any such proceeding in advance of its
final disposition. The Company maintains insurance, at its expense, to protect
itself and any director, officer, employee or agent of the Company against any
such expense, liability or loss, whether or not the Company would have the power
to indemnify such person against such expense, liability or loss under state
law.

Technologies, Inc. acquisition), the Company obtained representations from the

(B) FINANCIAL STATEMENT SCHEDULES
 
     All schedules specified under Regulation S-X for the Company are omitted
because they are either not applicable or required under the instructions, or
because the information required is already set forth in the consolidated
financial statements or related notes thereto.
 
ITEM 17.  UNDERTAKINGS.
 
     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions or otherwise, the registrants
have been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities 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 registrants in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of their counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by them is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such.
 
     The undersigned registrant hereby undertakes to provide to the underwriter
at the closing specified in the underwriting agreements, certificates in such
denominations and registered in such names as required by the underwriter to
permit prompt delivery to each purchaser.
