                        SUMMARY SELECTED FINANCIAL DATA

     The following table sets forth summary selected financial data of Waterlink
since its incorporation on December 7, 1994. The financial data presented for
the four fiscal years ended September 30, 1998 have been derived from
Waterlink's audited financial statements. The financial data presented for the
nine months ended June 30, 1998 and 1999 are derived from unaudited financial
statements which in our opinion include all adjustments, which were of a normal
recurring nature, necessary for a fair presentation of that information. The
financial data includes the operating results of each acquired business from the
date of acquisition in accordance with the purchase method of accounting. Our
results for the nine months ended June 30, 1999 are not necessarily indicative
of our future results.

     You should read the summary selected financial data in conjunction with,
and they are qualified by, our historical consolidated financial statements and
the related notes, "Selected Historical Consolidated Financial Data," and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" contained elsewhere in this prospectus.

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

(1) In connection with our 1999 Strategic Operating Plan, Waterlink decided to
    discontinue the manufacturing processes for our Great Lakes subsidiary
    product line in favor of utilizing subcontractors. As a result of this
    decision, during the nine months ended June 30, 1999, Waterlink recognized
    $2,137,000 of costs, or $0.14 per share, assuming dilution, comprised of
    $1,191,000 of cost overruns that took place on a contractual obligation and
    $946,000 of inventory write downs and other costs, which reduced gross
    profit.

(2) For the nine months ended June 30, 1999, selling, general and administrative
    expenses included $255,000, or $0.02 per share, assuming dilution, relating
    to the write off of costs associated with acquisition activity that ceased
    during the quarter ended June 30, 1999.

(3) Waterlink incurred special charges as follows:

     - During the fiscal year ended September 30, 1997 Waterlink incurred a
       special charge to operations of $2,630,000, or $0.21 per share, assuming
       dilution, resulting primarily from the issuance, concurrent with our
       initial public offering, of a ten year option to purchase 100,000 shares
       of common stock at a price of $0.10 per share to an officer of Waterlink
       pursuant to terms of an employment agreement. Of this amount,
       approximately $1,138,000 was non-cash and the remainder represented cash
       obligations related principally to the reimbursement of income taxes
       resulting from the stock option issuance.

     - During the fiscal year ended September 30, 1998, Waterlink incurred
       special charges of $21,636,000, or $1.70 per share, assuming dilution.
       These special charges are comprised of the following three components:

        - Waterlink recorded a charge of $2,858,000, or $0.23 per share,
          assuming dilution, primarily related to termination benefits and costs
          associated with the exiting of certain facilities to implement our
          1999 plan.

        - As a result of our decision to exit the Bioclear business, during the
          fourth quarter of fiscal 1998, Waterlink recorded a non-cash charge of
          $17,284,000, or $1.40 per share, assuming dilution, consisting of
          $15,967,000 related to the impairment of goodwill associated with the
          June 1997 acquisition of Bioclear Technology, Inc. and $1,317,000 to
          write off the cumulative translation adjustment component of
          Bioclear's equity.

        - Waterlink incurred special charges of $1,494,000, or $0.07 per share,
          assuming dilution, primarily attributable to contractual obligations
          to our former chief executive officer, who resigned in June 1998, and
          costs necessary to recruit executives to Waterlink.
                                        3

     - During the nine months ended June 30, 1998, Waterlink incurred special
       charges of $1,494,000, or $0.07 per share, assuming dilution, primarily
       attributable to contractual obligations to our former chief executive
       officer, who resigned in June 1998, and costs necessary to recruit
       executives to Waterlink.

     - During the nine months ended June 30, 1999, Waterlink incurred special
       charges of $2,787,000, or $0.20 per share, assuming dilution, for the
       following:

        - Continuing costs of $1,487,000, or $0.11 per share, assuming dilution,
          associated with implementing our 1999 plan, primarily related to
          termination benefits and facility consolidation costs.

        - In conjunction with our 1999 plan, we determined that we would exit
          the acquired Bioclear business. During the fourth quarter of fiscal
          1998, the assets of Bioclear, primarily related to Bioclear's
          manufacturing facility located in Winnipeg, Canada, were reduced to
          their estimated net realizable value. Based on the status of the sales
          process and Waterlink's June 1999 decision regarding how to best
          dispose of the facility, we further reduced the estimated net
          realizable value of these remaining assets by $1,300,000, or $0.09 per
          share, assuming dilution.

(4) Net income for fiscal 1997 reflects an extraordinary item. Waterlink used a
    portion of the proceeds from our initial public offering to repay
    substantially all of outstanding indebtedness. In addition, concurrent with
    the initial public offering Waterlink canceled a note purchase agreement. In
    connection with the early retirement of certain indebtedness and the
    cancellation of the note purchase agreement, Waterlink realized an
    extraordinary charge of $385,000, net of taxes of $257,000, or $0.05 per
    share, assuming dilution, related to the write off of unamortized debt
    issuance costs and discounts associated with this indebtedness.

                                  RISK FACTORS

     Before you invest in our common stock, you should be aware of the various
risk factors described below. You should carefully consider these factors,
together with all the other information included in this prospectus, before you
decide whether to purchase our common stock.

OUR QUARTERLY RESULTS OF OPERATIONS COULD FLUCTUATE SIGNIFICANTLY WHICH COULD
RESULT IN DEFAULTS UNDER OUR BANK CREDIT AGREEMENT AND IN VOLATILITY IN THE
MARKET PRICE OF OUR COMMON STOCK

     We need to finalize complicated contracts and orders with our customers
before we produce our revenues. Often, the timing of those contracts and orders
is also subject to our customers receiving financing, various permits and other
aspects outside our control. A delay in finalizing any of these contracts could
have a significant negative impact on our operating results in any fiscal
quarter. We believe that period-to-period comparisons of our operating results
are not necessarily meaningful and should not necessarily be relied upon as
indicators of our future performance. Since some of our financial covenants in
our bank credit agreement are based on quarterly results, these fluctuations
could result in our needing to negotiate amended terms or being in default of
our bank credit agreement. Also, these fluctuations in our quarterly results
could lead to our failure to meet expectations of securities analysts and
investors and could seriously harm the market price of our common stock.
Quarterly operating results have varied significantly in the past and will
likely vary significantly in the future.

OUR SUBSTANTIAL AMOUNT OF DEBT COULD LIMIT OUR GROWTH AND IMPOSES RESTRICTIONS
ON OUR BUSINESS

     We have incurred substantial indebtedness. Our level of debt and our recent
operating performance, including the impact of special charges to our income,
limit our ability to:

     - obtain additional financing to fund our strategy, capital expenditures
       and other general corporate purposes;

     - use operating cash flow in other areas of our business since we must
       dedicate a substantial portion of these funds to pay interest and retire
       debt; and

     - react to changing market conditions and economic downturns.

     Before giving effect to this offering, we had $87.1 million of indebtedness
as of June 30, 1999, and on an adjusted basis after giving effect to the use of
net proceeds in this offering, we would have had $73.1 million of indebtedness.

     Our debt agreements contain numerous financial and operating covenants that
limit our discretion which respect to certain business matters. These covenants
place significant restrictions on, among other things, our ability to:

     - incur additional indebtedness, both under the bank credit agreement and
       other debt agreements;

     - merge or consolidate with other entities;

     - make acquisitions;

     - repay our obligations; and

     - pay dividends and other distributions.

                                        5

WE HAVE A LIMITED COMBINED OPERATING HISTORY AND ARE STILL IN THE PROCESS OF
INTEGRATING THOSE ACQUISITIONS THAT WE HAVE COMPLETED

     We were formed in December, 1994 and have grown principally through the
acquisition of existing businesses. Our success depends, in part, on our ability
to integrate the operations of our various businesses, including centralizing
some functions to achieve cost savings and developing programs and processes
that will promote cooperation in the sharing of opportunities and resources
among our businesses. Our 1999 plan and our restructured organization are
intended to continue to promote our ongoing integration process. Our management
group has been assembled for only a relatively short time with several key
people joining us within the last two fiscal years.

THE DEMAND FOR OUR PRODUCTS IS CYCLICAL

     Much of our water purification and wastewater equipment requires
significant capital expenditures by our customers. As such, the timing of
customer purchases from us is affected by various economic factors, including
interest rate and business cycle fluctuations, the timing and process of
government funding and the setting of rates by regulators, all of which are
beyond our control. The cyclical nature of capital equipment sales could have an
adverse affect on our revenues and profitability in general and on our revenues
and profitability in any particular quarterly financial reporting period.

OUR INDUSTRY IS HIGHLY COMPETITIVE

     Our industry, the water purification and wastewater treatment industry, is
fragmented and highly competitive due to the large number of businesses within
certain product areas. We compete 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 projects. While we
believe we are well positioned to deliver technology and services at a fair
price, some of our competitors have developed product and service integration
capabilities beyond our current scope.

WE ARE DEPENDENT ON KEY PERSONNEL

     Our business depends on our ability to hire and retain our executive
officers and senior management. Our business could be adversely affected if for
any reason any of our executive officers or senior managers cease to be employed
by us. In addition, we will be dependent on the senior managers of any
significant businesses we may acquire in the future and on our ability to
attract and retain qualified managers to support our internal expansion.

WE MAY LOSE OUR NEW YORK STOCK EXCHANGE LISTING

     We have a market capitalization of $          , based on a stock price of
$          and                outstanding shares of common stock
on              , 1999 and stockholders' equity of $          on June 30, 1999.
Currently, we fall below the New York Stock Exchange listing requirement for
market capitalization and stockholders' equity. We believe that we will satisfy
the continued listing requirements of the New York Stock Exchange following
successful completion of this offering. If our shares were not listed on the New
York Stock Exchange, then we would attempt to have the shares listed on another
stock market. We currently do not satisfy the original listing requirements for
trading on the NASDAQ National Market System.

THE MEMBERS OF OUR BOARD OF DIRECTORS AND MANAGEMENT WILL OWN APPROXIMATELY
18.9% OF OUR COMMON STOCK AND CAN EXERCISE SIGNIFICANT INFLUENCE OVER OUR
AFFAIRS. ALSO, SEVERAL INSTITUTIONAL INVESTORS WILL OWN SUBSTANTIAL PERCENTAGES
OF OUR COMMON STOCK

     After the closing of the offering our directors and management will own or
control, in the aggregate, approximately 18.9% of our common stock. In addition,
two institutional investors, the State of Wisconsin Investment Board and T. Rowe
Price Associates, Inc. will own or control approximately [     ]% and 9.9%,
respectively, of our common stock. Accordingly, these individuals and
institutional investors, if acting together or even alone, can exercise
significant influence over our affairs including the election of our directors,
appointment of our management and approval of actions requiring the approval of
our stockholders, which may include the adoption of amendments to our
certificate of incorporation, the approval of mergers or sales of all or
substantially all our assets, and similar items. The concentration of voting
power of these stockholders, if they act together, could, under certain
circumstances, have the effect of delaying or preventing a change in control of
Waterlink. See "Common Stock Ownership."

OUR FOREIGN OPERATIONS ARE SUBJECT TO POLITICAL AND ECONOMIC RISKS AND WE MAY BE
ADVERSELY AFFECTED BY FOREIGN CURRENCY FLUCTUATION

     We sell a substantial proportion of our systems, equipment and services in
Western Europe, Latin America and other regions outside the United States. Also,
a number of our divisions operate outside of the United States. Our net sales
outside the United States were approximately 48.4% of our net sales for the nine
months ended June 30, 1999. Political, economic, regulatory and social
conditions in foreign countries in which we operate may change. Risks associated
with sales and operations in foreign countries include risks of:

     - war

     - expropriation or nationalization of assets

     - renegotiation or nullification of existing contracts

     - changing political conditions

     - changing laws and policies affecting trade, taxation and investment

     - overlap of different tax structures

     - the general hazards associated with the assertion of sovereignty over
       certain areas in which operations are conducted

     Because our reporting currency is the United States dollar, our operations
outside the United States sometimes face the additional risks of fluctuating
currency values and exchange rates, hard currency shortages and controls on
currency exchange. We are subject to the impact of foreign currency fluctuations
and exchange rate charges on our reporting for results from those operations in
our financial statements.

WE MAY BE SUBJECT TO LIABILITY UNDER ENVIRONMENTAL LAWS

     In the United States, the Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended, and comparable state laws,
impose liability without fault for the releases of hazardous substances into the
environment. Potentially responsible parties include (a) owners and operators of
a site, (b) parties which create the hazardous

                                        7
<PAGE>   11

substances released at a site, and (c) parties which arrange for the
transportation or disposal of hazardous substances. We 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 of the treatment process in
violation of law. We are also subject to environmental laws in countries outside
the United States where we operate or in which our 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.

CHANGES IN ENVIRONMENTAL LAWS COULD AFFECT OUR BUSINESS

     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 our ability to sell our
solutions, systems and equipment. To the extent that demand for our solutions,
systems and equipment is created by the need to comply with environmental laws
and regulations, any modification of the standards imposed by these laws and
environmental laws and regulations may reduce demand for our products and
services, thereby adversely affecting our business and prospects.

OUR LONG-TERM GROWTH STRATEGY IS DEPENDENT ON COMPLETING ACQUISITIONS

     While net proceeds from this offering are not expected to be utilized for
acquisition activity, over the long-term, we intend to significantly grow by
acquiring other businesses. Our current capital structure does not support an
acquisition program. We intend to use a combination of our common stock, cash
and debt obligations to make these future acquisitions. The extent to which we
are able to use our common stock for this purpose will depend on its market
value from time to time and the willingness of potential sellers to accept it as
full or partial payment. To the extent we are unable to use our common stock to
make acquisitions, our ability to grow may be limited to funds from internally
generated cash flow over and above our other cash needs and our ability to incur
additional indebtedness. Our current capital structure may make it more
difficult for us to borrow money to use for acquisitions.

     An acquisition strategy such as ours involves risks inherent in assessing
the values, strengths, weaknesses and profitability of acquisition candidates.
Historically, we have been successful in identifying potential acquisition
candidates. As consolidation continues in the industry, the prices for
attractive acquisition candidates may be higher than we have paid and may make
an acquisition strategy for growth less viable.

INVESTORS WILL EXPERIENCE IMMEDIATE DILUTION

     The offering price per share will exceed the net tangible book value per
share of our common stock. Accordingly, investors purchasing shares in this
offering will incur immediate and substantial dilution of approximately $3.68 in
the book value per share of the common stock from an assumed $3.00 price per
share paid for the common stock. See "Dilution."

                                        8
<PAGE>   12

OUR BUSINESS IS SUBJECT TO POTENTIAL WARRANTY AND PERFORMANCE GUARANTEE CLAIMS

     Some of our customers require us to guarantee that our services and
products will be of a specified level of quality or performance. If a product or
service fails to attain that level of quality or performance, we could incur
significant financial penalties.

WE FACE MANY UNKNOWN RISKS ASSOCIATED WITH YEAR 2000 PROBLEMS

     Many currently installed computer systems and software products are
dependant upon internal calendars coded to accept only two digit entries in the
date code field. These date code fields will need to accept four digit entries
to distinguish dates after the beginning of year 2000 from those before. While
we believe that we have a program established to resolve the year 2000 issue in
a timely manner in our computer systems, we may not have resolved all issues.
Also, we depend on third parties, including suppliers, subcontractors and
customers, for the operation of our day-to-day business. If they fail to correct
their year 2000 problems, failures or interruptions to our business may occur,
resulting in significant financial and other problems. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

PROVISIONS OF OUR CORPORATE DOCUMENTS COULD DELAY OR PREVENT A CHANGE IN CONTROL
OF WATERLINK

     Our certificate of incorporation and bylaws contain certain provisions
which may have anti-takeover effects and may discourage, delay, or prevent a
takeover attempt that a stockholder might consider in his best interest. These
documents allow our board of directors to authorize the issuance of preferred
stock, which could adversely affect the voting and other rights of the holders
of our common stock, provide that our directors are classified into three
classes with staggered terms, and contain a "fair price provision" which imposes
restrictions in the event of certain business combinations. See "Description of
Capital Stock."

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus contains forward-looking statements. Except for statements
of historical facts, all statements may be forward-looking statements that
involve risks and uncertainties. These statements are only predictions. Actual
events or results may differ materially from forward-looking results for a
number of reasons, including:

     - changes in world economic conditions, including:

        - instability of governments and legal systems in countries in which
          Waterlink conducts business

        - significant changes in currency valuations

        - recessionary environments

        - year 2000 compliance issues relating to Waterlink's programs and
          external parties, including suppliers and customers

        - the effects of military conflicts

                                        9
<PAGE>   13

     - changes in customer demand and timing of orders as they affect sales and
       product mix, including:

        - the effect of delays in government approvals and funding

        - the effect of strikes at customer's facilities

        - variations in backlog

        - the impact of changes in industry business cycles

     - competitive factors, including:

        - changes in market penetration

        - introduction of new products, services or financing alternatives by
          existing and new competitors

     - changes in operating costs, including:

        - changes in Waterlink's and its subcontractors' manufacturing processes

        - changes in costs associated with varying levels of operations

        - changes resulting from different levels of customers demands

        - effects of unplanned work stoppages

        - changes in cost of labor and benefits

        - the cost and availability of raw materials and energy

     - the success of Waterlink's strategic plan

     - the ability to raise sufficient additional capital

     - the ability to amend Waterlink's bank credit agreement

     - unanticipated litigation, claims or assessments

                                USE OF PROCEEDS

     The shares are being sold by Waterlink for an assumed aggregate net price
of $18.2 million. We are using the net proceeds of this sale to repay $14.0
million of outstanding debt under our bank credit agreement and the remainder of
the net proceeds will be used for general corporate purposes. The amounts
outstanding under our bank credit agreement currently bears interest at 7.93%
per year. All amounts outstanding under our bank credit agreement mature on May
19, 2003.

                                DIVIDEND POLICY

     We have not paid or declared any dividends on our common stock since our
inception. We anticipate that, following the completion of the offering,
earnings will be retained to support the growth of our business and will not be
distributed to stockholders as dividends. The declaration and payment of any
future dividends and the amount of any dividend will be determined by our board
of directors and will depend upon our results of operations, financial
condition, cash requirements, future prospects, limitations imposed by bank
credit and debt agreements and other factors deemed relevant by our board of
directors. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."

                                       10
<PAGE>   14

     Pursuant to our bank credit agreement, we may not declare or make, or agree
to declare or make, directly or indirectly, any dividends, except that we may
declare and pay dividends with respect to our capital stock payable solely in
additional shares of our common stock or options, warrants or other rights to
purchase our common stock.

                                    DILUTION

     Our deficit in consolidated net tangible book value as of June 30, 1999 was
$31.1 million or $2.46 per share of our common stock. After giving effect to the
sale of the shares of our common stock in this offering (at an assumed offering
price of $3.00 per share) and after deducting anticipated offering expenses, our
adjusted deficit in consolidated net tangible book value as of June 30, 1999
would have been $12.9 million or $0.68 per share, representing an immediate
$3.68 per share dilution to new investors purchasing shares at the offering
price. The following table illustrates such per share dilution.

                SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA

     The following table sets forth selected historical consolidated financial
data of Waterlink since its incorporation on December 7, 1994. The financial
data presented for the four fiscal years ended September 30, 1998 have been
derived from Waterlink's audited financial statements. The financial data
presented for the nine months ended June 30, 1998 and 1999 are derived from
unaudited financial statements which in our opinion include all adjustments,
which were of a normal recurring nature, necessary for a fair presentation of
that information. The financial data includes the operating results of each
acquired business from the date of acquisition in accordance with the purchase
method of accounting. Our results for the nine months ended June 30, 1999 are
not necessarily indicative of future results.

     You should read the selected historical consolidated financial data in
conjunction with, and they are qualified by, our historical consolidated
financial statements and the related notes and "Management's Discussion and
Analysis of Financial Condition and Results of Operations," contained elsewhere
in this prospectus.

(1) In connection with our 1999 plan, Waterlink decided to discontinue the
    manufacturing processes for our Great Lakes subsidiary product line in favor
    of utilizing subcontractors. As a result of this decision, during the nine
    months ended June 30, 1999, Waterlink recognized $2,137,000 of costs, or
    $0.14 per share, assuming dilution, comprised of $1,191,000 of cost overruns
    that took place on a contractual obligation and $946,000 of inventory write
    downs and other costs.

(2) For the nine months ended June 30, 1999, selling, general and administrative
    expenses included $255,000, or $0.02 per share, assuming dilution, relating
    to the write off of costs associated with acquisition activity that ceased
    during the quarter ended June 30, 1999.

(3) Waterlink incurred special charges as follows:

     - During the fiscal year ended September 30, 1997 Waterlink incurred a
       special charge to operations of $2,630,000, or $0.21 per share, assuming
       dilution, resulting primarily from the issuance, concurrent with our
       initial public offering, of a ten year option to purchase 100,000 shares
       of common stock at a price of $0.10 per share to an officer of Waterlink
       pursuant to

                                       15
<PAGE>   19

       terms of an employment agreement. Of this amount, approximately
       $1,138,000 was non-cash and the remainder represented cash obligations
       related principally to the reimbursement of income taxes resulting from
       the stock option issuance.

     - During the fiscal year ended September 30, 1998, Waterlink incurred
       special charges of $21,636,000, or $1.70 per share, assuming dilution.
       These special charges are comprised of the following three components:

        - Waterlink recorded a charge of $2,858,000, or $0.23 per share,
          assuming dilution, primarily related to termination benefits and costs
          associated with the exiting of certain facilities to implement our
          1999 plan.

        - As a result of our decision to exit the Bioclear business, during the
          fourth quarter of fiscal 1998, Waterlink recorded a non-cash charge of
          $17,284,000, or $1.40 per share, assuming dilution, consisting of
          $15,967,000 related to the impairment of goodwill associated with the
          June 1997 acquisition of Bioclear Technology, Inc. and $1,317,000 to
          write off the cumulative translation adjustment component of
          Bioclear's equity.

        - Waterlink incurred special charges of $1,494,000, or $0.07 per share,
          assuming dilution, primarily attributable to contractual obligations
          to our former chief executive officer, who resigned in June 1998, and
          costs necessary to recruit executives to Waterlink.

     - During the nine months ended June 30, 1998, Waterlink incurred special
       charges of $1,494,000, or $0.07 per share, assuming dilution, primarily
       attributable to contractual obligations to our former chief executive
       officer, who resigned in June 1998, and costs necessary to recruit
       executives to Waterlink.

     - During the nine months ended June 30, 1999, Waterlink incurred special
       charges of $2,787,000, or $0.20 per share, assuming dilution, for the
       following:

        - Continuing costs of $1,487,000, or $0.11 per share, assuming dilution,
          associated with the implementation of Waterlink's 1999 plan, primarily
          related to termination benefits and facility consolidation costs.

        - In conjunction with our 1999 plan, we determined that we would exit
          the acquired Bioclear business. During the fourth quarter of fiscal
          1998, the assets of Bioclear, primarily related to Bioclear's
          manufacturing facility located in Winnipeg, Canada, were reduced to
          their estimated net realizable value. Based on the status of the sales
          process and Waterlink's June 1999 decision regarding how to best
          dispose of the facility, we further reduced the estimated net
          realizable value of these remaining assets by $1,300,000, or $0.09 per
          share, assuming dilution.

(4) Net income for fiscal 1997 reflects an extraordinary item. Waterlink used a
    portion of the proceeds from its initial public offering to repay
    substantially all of its outstanding indebtedness. In addition, concurrent
    with the initial public offering Waterlink canceled a note purchase
    agreement. In connection with the early retirement of certain indebtedness
    and the cancellation of the note purchase agreement, Waterlink realized an
    extraordinary charge of $385,000, net of taxes of $257,000, or $0.05 per
    share, assuming dilution, related to the write off of unamortized debt
    issuance costs and discounts associated with this indebtedness.

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

     The following discussion should be read in conjunction with the audited
consolidated financial statements and notes thereto included elsewhere in this
prospectus.

OVERVIEW

     Waterlink 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 externally by completing thirteen acquisitions.

     The current focus of Waterlink is the implementation of its 1999 Strategic
Operating Plan. The 1999 plan is being implemented in three phases: the
restructuring phase, the cost reduction phase, and the growth phase.

     The restructuring phase was completed prior to October 1, 1998, the
beginning of Waterlink's current fiscal year, and restructured Waterlink from a
holding company that completed 13 acquisitions consisting of 23 separate
operating companies into the following five fully integrated divisions that are
focused on their specific markets:

     - the Biological Wastewater Treatment Division

     - the Separations Division

     - the Pure Water Division

     - the Specialty Products Division

     - the European Water and Wastewater Division

     This divisional structure allows Waterlink to utilize the strengths of its
complementary product lines and brand name to work closer with customers.

     The following table shows our 13 acquisitions to date, consisting of 23
operating companies, and where the acquired companies operate within our five
divisions.

     The cost reduction phase established goals of reducing selling, general and
administrative expenses by $4.3 million in fiscal 1999, principally by reducing
the number of employees by 75, or approximately 10% of the work force, and by
closing seven facilities. Waterlink has decided to curtail its manufacturing
activities whenever possible, in favor of partnering with vendors who
manufacture components used in our systems and equipment. As of June 30, 1999,
the total number of employees has been reduced by 114 people, in excess of the
75 originally contemplated by the 1999 plan, and the annualized cost savings
goal of $4.3 million has been surpassed by approximately $1.1 million. With
regard to facilities, six have been closed and the remaining one is scheduled to
relocate before September 30, 1999, the end of Waterlink's fiscal year.

     The cost reduction phase also includes an initiative to reduce production
costs by identifying common suppliers among divisions and consolidating
purchases to increase Waterlink's purchasing power. Supply contracts with these
common vendors are expected to provide cost savings to help Waterlink remain
competitive in the long term.

     Waterlink is now focused on implementing the growth phase of the 1999 plan,
which provides for adding at least 25 sales and marketing professionals this
fiscal year, 15 of whom have already accepted positions, in order to improve
revenue performance over the long term. These additional costs will be funded,
in part, by the additional $1.1 million of annualized savings as a result of the
cost reduction phase of the 1999 plan.

     The improved communications and specific identification of markets and
products resulting from the restructuring of Waterlink, together with the
reinvestment in sales and marketing professionals, are intended to allow
Waterlink to increase its sales efforts. Two specific areas of focus are the
implementation of a key account program with selected worldwide buyers of
Waterlink product offerings, and our integrated systems effort that is expected
to provide more interdivisional cross selling opportunities with certain key
customers. Waterlink is also developing sales strategies in regions where we do
not currently have a significant presence or wish to increase our opportunities,
like South America. The growth phase of the 1999 plan is expected to help build
Waterlink into a sales, marketing and engineering leader in the industry,
focused on profitable growth over the long term.

     Waterlink's new organization is also designed to more efficiently integrate
future acquisitions. Waterlink's current capital structure does not support an
acquisition program. Waterlink's intends to improve its capital structure
through a combination of improved operating performance and access to capital
markets, which we expect will enable us to resume our acquisition program.
Acquisitions are expected to play a strategic role in Waterlink's future to
increase competitiveness, spur revenue and earnings growth, and enhance our
total solutions capability.

                                       18

     All acquisitions have been 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 are not
necessarily comparable or indicative of operating results for current or future
periods.

     The majority of the systems and equipment produced by Waterlink 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 incurred 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. Provisions are made
currently for all known or anticipated losses. Variations from estimated
contract performance could result in a material adjustment to operating results
for any fiscal quarter or year. Claims for extra work or changes in scope of
work are included in revenues when collection is probable. Revenues from
remaining systems and equipment sales are recognized when shipped.

     In the past Waterlink has experienced quarterly fluctuations in operating
results due to the contractual nature of its business and the consequent timing
of these orders. As part of its strategic plan, Waterlink expects that it may
receive contracts that are significantly larger than those received by Waterlink
historically. In addition, certain of the 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 the ability to receive any necessary
permits to commence the project. Therefore, Waterlink 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 Waterlink of revenues and profits. In
addition, Waterlink has historically operated with a moderate backlog. However,
as a result of its strategic plan, Waterlink anticipates that both the dollar
volume and number of contracts in its backlog will increase significantly. As of
June 30, 1999, Waterlink's total backlog was approximately $46.0 million,
consisting of $39.8 million of written purchase orders for capital goods
equipment and $6.2 million of firm commitments to purchase recurring revenue
products from our specialty products division. Quarterly sales and operating
results will 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
Waterlink's operating results in any particular period. Because of these
factors, Waterlink believes that period-to-period comparisons of its operating
results are not necessarily indicative of future performances.

</TABLE>

YEAR ENDED SEPTEMBER 30, 1998 COMPARED TO YEAR ENDED SEPTEMBER 30, 1997

     NET SALES: Net sales for the year ended September 30, 1998 were
$135,167,000, an increase of $70,468,000 from the prior year. The increase was
due to the timing of the acquisitions previously described. Waterlink
experienced negative internal growth for the year of 10.8%, resulting
principally from the timing of orders, exchange rate fluctuations and stronger
performance for specific domestic locations during fiscal 1997 that was not
duplicated in fiscal 1998. Waterlink measures internal growth by comparing each
subsidiary's net sales from the months subsequent to their respective
acquisition dates during the prior year to those same months in the current
year.

     GROSS PROFIT: Gross profit for the year ended September 30, 1998 was
$49,635,000, an increase of $25,326,000 from the prior year. The increase was
primarily due to the acquisitions previously described. Gross margin was 36.7%
for 1998 as compared to 37.6% for 1997. Gross margins have been impacted by the
March 1997 acquisition of the nordic water products group and the June 1998
acquisition of the specialty products division, both of which historically
experience lower margins as compared to other Waterlink divisions.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES; Selling, general and
administrative expenses for the year ended September 30, 1998 were $38,639,000,
an increase of $19,956,000 from the prior year. The increase was primarily due
to the acquisitions previously described. Selling, general and administrative
expenses as a percentage of net sales was 28.6% for 1998 as compared to 28.9%
for 1997. This decrease primarily reflects the spreading of selling, general and
administrative expenses over a larger revenue base.

     SPECIAL CHARGES: During the year ended September 30, 1998, Waterlink
incurred special charges of $21,636,000. These special charges consisted of the
following three components:

     - Waterlink recorded a charge of $2,858,000 primarily related to
       termination benefits and costs associated with the exiting of facilities
       in connection with the implementation of our 1999 plan.

     - Waterlink recorded a non-cash charge of $17,284,000, consisting of
       $15,967,000 related to the impairment of goodwill associated with the
       June 1997 acquisition of Bioclear and $1,317,000 to write off the
       cumulative translation adjustment component of Bioclear's equity. With
       regard to the $17,284,000 impairment charge, our 1999 plan includes
       Waterlink's decision to exit the acquired business of Bioclear. Several
       factors lead to this decision including:

        - The lack of orders at Bioclear in fiscal 1998 led to a comprehensive
          market review, which was completed in August 1998. This analysis
          indicated that Bioclear's originally perceived niche market was not
          reliable and possibly nonexistent.

        - In order to compete in more traditional markets, Bioclear's
          proprietary product would need to be reengineered, at great expense,
          to significantly reduce the water treatment cost per gallon. In
          addition, this reengineered proprietary product would not guarantee
          success due to the extremely competitive traditional marketplace.

        - In July 1998, Bioclear's founder, a former owner and president,
          resigned.

        - In August 1998, Bioclear's chief engineer and a former owner announced
          his desire to reduce his involvement to part time, making the
          reengineering effort more difficult.

       Having made the decision to exit the business, the remaining goodwill
       associated with the Bioclear acquisition was not recoverable based on
       Bioclear's lack of future undiscounted cash flows and was impaired. Once
       the impairment was determined, Waterlink obtained an independent
       appraisal of the fair value of the Bioclear business. This appraisal
       indicated no value for the business above the identified tangible net
       assets. As a result, Waterlink wrote off the unamortized balance of
       goodwill of $15,967,000. Since this was deemed to be a substantially
       complete liquidation of an investment in a foreign entity, Waterlink also
       wrote off $1,317,000 of the cumulative translation adjustment relating to
       Bioclear's equity.

     - Waterlink incurred special charges of $1,494,000 primarily attributable
       to contractual obligations to our former president and chief executive
       officer, who resigned in June 1998, and costs necessary to recruit
       executives to Waterlink.

     Waterlink incurred special charges of $2,630,000 for the year ended
September 30, 1997 resulting primarily from the issuance at the time of our
initial public offering of a ten year option to purchase 100,000 shares of
common stock at a price of $0.10 per share to
                                       21
<PAGE>   25

an officer of Waterlink pursuant to terms of an employment agreement. Of this
amount, approximately $1,138,000 was non-cash and the remainder represented cash
obligations related principally to the reimbursement of income taxes resulting
from the stock option issuance.

     AMORTIZATION: Amortization expense for the year ended September 30, 1998
was $1,871,000, an increase of $1,120,000 from the prior year. The increase was
primarily due to the goodwill resulting from the acquisitions previously
described.

     INTEREST EXPENSE; Interest expense for the year ended September 30, 1998
was $3,562,000, an increase of $2,281,000 from the prior year. This increase was
primarily due to increased borrowings related to the Waterlink's ongoing
acquisition program.

     INCOME TAXES: Waterlink recorded an income tax provision of $1,468,000 on a
pre-tax loss of $16,036,000. Waterlink was required to record income tax expense
on its earnings outside the United States and was also required to record income
tax expense in several states domestically. In addition, due to the net
operating loss carryforward in the United States, we had to fully reserve for
deferred tax assets that had been recorded in the previous year.

YEAR ENDED SEPTEMBER 30, 1997 COMPARED TO YEAR ENDED SEPTEMBER 30, 1996

     NET SALES: Net sales for the year ended September 30, 1997 were
$64,699,000, an increase of $44,898,000 from the prior year. The increase was
primarily due to our acquisitions. In addition, internal growth accounted for
$6,830,000 of the increase, which represented an internal growth rate of 34.5%.
The growth was primarily due to expansion in overseas markets and to the greater
levels of resources provided by Waterlink to the businesses subsequent to the
acquisitions.

     GROSS PROFIT: Gross profit for the year ended September 30, 1997 was
$24,309,000, an increase of $15,741,000 from the prior year. The increase was
primarily due to our acquisitions and internal growth. Gross margin was 37.6%
for 1997 as compared to 43.3% for 1996. Gross margins have been impacted by the
March 1997 acquisition of the nordic water products group which historically
experiences lower margins as compared to other Waterlink divisions, as well as
by a large, lower-margin, design-build project in Germany that is near
completion at the end of the fiscal year.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES: Selling, general and
administrative expenses for the year ended September 30, 1997 were $18,683,000,
an increase of $11,654,000 from the prior year. The increase was primarily due
to the acquisitions previously described. Selling, general and administrative
expenses as a percentage of net sales was 28.9% for 1997 as compared to 35.5%
for 1996. This decrease primarily reflects the spreading of selling, general and
administrative expenses over a larger revenue base.

     SPECIAL CHARGES: Special management compensation of $2,630,000 for the year
ended September 30, 1997 resulted primarily from the issuance at the time of our
initial public offering of a ten year option to purchase 100,000 shares of
Common Stock at a price of $0.10 per share to an officer of Waterlink pursuant
to terms of an employment agreement. Of this amount, approximately $1,138,000 is
non-cash and the remainder represents cash obligations related principally to
the reimbursement of income taxes resulting from the stock option issuance.

     AMORTIZATION: Amortization expense for the year ended September 30, 1997
was $751,000, an increase of $444,000 from the prior year. The increase was
primarily due to the goodwill resulting from the acquisitions previously
described.
                                       22
<PAGE>   26

     INTEREST EXPENSE: Interest expense for the year ended September 30, 1997
was $1,281,000, an increase of $404,000 from the prior year. This increase was
primarily related to increased borrowings required to finance the acquisitions
previously described.

     EXTRAORDINARY ITEM: During the year ended September 30, 1997, Waterlink
recorded an extraordinary charge of $385,000, net of taxes of $257,000, related
to:

     - the write-off of unamortized debt issuance costs from indebtedness we
       repaid with the net proceeds from our initial public offering

     - discounts associated with a note purchase agreement which was terminated
       at the time of our initial public offering.

THREE MONTHS ENDED JUNE 30, 1999 COMPARED TO THREE MONTHS ENDED JUNE 30, 1998

     NET SALES:  Net sales for the three months ended June 30, 1999 were
$43,083,000, an increase of $8,146,000 from the comparable prior period. The
increase was due to the acquisition on June 5, 1998 of Barnebey & Sutcliffe
Corporation, Sutcliffe Speakman Carbons Limited and Sutcliffe Croftshaw Limited,
which we collectively refer to as our specialty products division. Waterlink
experienced negative internal growth for the quarter of 6.8%, resulting
primarily from the timing of orders at two specific domestic locations. If
currency rate fluctuations were excluded, negative internal growth for the
quarter would have been 4.5%. Waterlink measures internal growth by comparing
each subsidiary's net sales from the months subsequent to their respective
acquisition dates during the prior year to those same months in the current
year.

     GROSS PROFIT:  Gross profit for the three months ended June 30, 1999 was
$11,854,000, a decrease of $1,696,000 from the comparable prior period. Gross
margin was 27.5% for the 1999 period as compared to 38.8% for the 1998 period.
We decided to discontinue the manufacturing processes for our Great Lakes
subsidiary product line in favor of utilizing subcontractors. As a result of
this decision, during the quarter ended June 30, 1999, Waterlink recognized
$2,137,000 of costs, comprised of $1,191,000 of cost overruns that took place on
a contractual obligation and $946,000 of inventory write downs and other costs.
Absent the $2,137,000 of costs associated with the exit of the Great Lakes
facility, the gross margin would have been 32.5% for the three months ended June
30, 1999. The adjusted gross margin of 32.5% is lower than the 38.8% realized in
the 1998 period primarily due to the timing of the acquisition of the specialty
products division, which is included in operations for one month in 1998 versus
three months in 1999. The specialty products division experiences lower margins
as compared to other Waterlink divisions.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES:  Selling, general and
administrative expenses for the three months ended June 30, 1999 were
$11,600,000, an increase of $894,000 from the comparable prior period. The
increase was primarily due to the acquisition of the specialty products
division. Selling, general and administrative expenses as a percentage of net
sales were 26.9% in 1999 as compared to 30.6% for the comparable prior period.
This decrease primarily reflects the costs savings realized from Waterlink's
1999 plan; as well as the impact of the June 1998 acquisition of the specialty
products division, which historically experiences a lower percentage of selling,
general and administrative expenses as a percentage of sales as compared to
other Waterlink divisions. Selling, general and administrative expenses for the
three months ended June 30, 1999 were increased by a charge of $255,000 from the
write off of costs associated with acquisition activity that ceased during the
quarter. Absent this write off, the increase from

                                       23
<PAGE>   27

the 1998 period would have been $639,000 and selling, general and administrative
expenses as a percentage of sales would have been 26.3% for the three months
ended June 30, 1999.

     SPECIAL CHARGES:  Special charges of $2,084,000 during the three months
ended June 30, 1999 consisted of the following:

     - Continuing costs of $784,000 associated with the implementation of
       Waterlink's 1999 plan, primarily related to termination benefits and
       facility consolidation costs.

     - In conjunction with our 1999 plan, we determined that we would exit the
       acquired Bioclear business. During the fourth quarter of fiscal 1998, the
       assets of Bioclear, primarily related to Bioclear's manufacturing
       facility located in Winnipeg, Canada, were reduced to their estimated net
       realizable value. Based on the status of the sales process and
       Waterlink's June 1999 decision regarding how to best dispose of the
       facility, we further reduced the estimated net realizable value of these
       remaining assets by $1,300,000.

     We expect to recognize additional special charges associated with our 1999
plan of approximately $213,000 during the remainder of fiscal 1999.

     Waterlink incurred special charges of $1,494,000 during the three months
ended June 30, 1998 primarily attributable to contractual obligations to our
former chief executive officer, who resigned in June 1998, and costs necessary
to recruit executives to Waterlink.

     AMORTIZATION:  Amortization expense for the three months ended June 30,
1999 was $515,000, a decrease of $55,000 from the comparable prior period. This
net decrease has two components. First, amortization expense was reduced by
$107,000 from the exit of Waterlink's Bioclear business during the fourth
quarter of fiscal 1998. Second, this reduction was partially offset by $52,000
of additional amortization of goodwill associated with the June 1998 acquisition
of the specialty products division.

     INTEREST EXPENSE:  Interest expense for the three months ended June 30,
1999 was $1,702,000, an increase of $684,000 from the comparable prior period
primarily due to increased borrowings related to Waterlink's fiscal 1998
acquisitions. We expect interest expense to increase by approximately $100,000
per quarter as a result of an interest rate increase effected in the fifth
amendment to our bank credit agreement.

     INCOME TAXES:  Waterlink recorded income taxes of $367,000 on a pre-tax
loss of $4,194,000 for the three months ended June 30, 1999. This income tax
expense was recorded on our earnings outside the United States and in certain
states domestically. For the three months ended June 30, 1998, Waterlink
recorded income taxes of $75,000 on a pre-tax loss of $93,000 due to
non-deductible goodwill amortization in connection with certain of its
acquisitions.

NINE MONTHS ENDED JUNE 30, 1999 COMPARED TO NINE MONTHS ENDED JUNE 30, 1998

     NET SALES:  Net sales for the nine months ended June 30, 1999 were
$128,858,000, an increase of $34,591,000 from the comparable prior period. The
increase was due to the acquisition of Chemitreat Services, Inc, on March 2,
1998; of Aquafine Engineering Services Limited and Purac Engineering
Incorporated in a single transaction on March 25, 1998; and of the specialty
products division on June 5, 1998. Waterlink experienced negative internal
growth for the nine months of 16.1%, resulting primarily from significant
revenues generated by German-based sales activity and a Utah-based land
development wastewater project in the comparable prior period. Excluding these
two factors, internal

                                       24
<PAGE>   28

growth would have declined by 6.4% due to the timing of orders at two specific
domestic locations. Further, if currency rate fluctuations were excluded,
negative internal growth for the nine months would have been 5.5%.

     GROSS PROFIT:  Gross profit for the nine months ended June 30, 1999 was
$40,151,000, an increase of $4,481,000 from the comparable prior period due to
the acquisitions. Gross margin was 31.2% for the 1999 period as compared to
37.8% for the 1998 period. We decided to discontinue the manufacturing processes
for our Great Lakes subsidiary product line in favor of utilizing
subcontractors. As a result of this decision, during the nine months ended June
30, 1999, Waterlink recognized $2,137,000 of costs, comprised of $1,191,000 of
cost overruns that took place on a contractual obligation and $946,000 of
inventory write downs and other costs. Absent the $2,137,000 of costs associated
with the exit of the Great Lakes facility, the gross margin would have been
32.8% for the nine months ended June 30, 1999. The adjusted gross margin of
32.8% is lower than the 37.8% realized in the 1998 period primarily due to the
June 1998 acquisition of the specialty products division, which historically
experiences lower margins as compared to other Waterlink divisions.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES:  Selling, general and
administrative expenses for the nine months ended June 30, 1999 were
$32,829,000, an increase of $5,371,000 from the comparable prior period. The
increase was primarily due to the acquisitions. Selling, general and
administrative expenses as a percentage of net sales were 25.5% in 1999 as
compared to 29.1% for the comparable prior period. This decrease primarily
reflects the costs savings realized from Waterlink's 1999 plan; as well as the
impact of the June 1998 acquisition of the specialty products division, which
historically experiences a lower percentage of selling, general and
administrative expenses as a percentage of sales as compared to other Waterlink
divisions. The selling, general and administrative expenses for the nine months
ended June 30, 1999 were increased by a charge of $255,000 from the write off of
costs associated with acquisition activity that ceased during the quarter ended
June 30, 1999.

     SPECIAL CHARGES:  Special charges of $2,787,000 during the nine months
ended June 30, 1999 related to the following:

     - Continuing costs of $1,487,000 associated with the implementation of
       Waterlink's 1999 plan, primarily related to termination benefits and
       facility consolidation costs.

     - In conjunction with our 1999 plan, we determined that we would exit the
       acquired Bioclear business. During the fourth quarter of fiscal 1998, the
       assets of Bioclear, primarily related to Bioclear's manufacturing
       facility located in Winnipeg, Canada, were reduced to their estimated net
       realizable value. Based on the status of the sales process and
       Waterlink's June 1999 decision regarding how to best dispose of the
       facility, we further reduced the estimated net realizable value of these
       remaining assets by $1,300,000.

     We expect to recognize additional special charges associated with our 1999
plan of approximately $213,000 during the remainder of fiscal 1999.

     Waterlink incurred special charges of $1,494,000 during the nine months
ended June 30, 1998 primarily attributable to contractual obligations to our
former chief executive officer, who resigned in June 1998, and costs necessary
to recruit executives to Waterlink.

     AMORTIZATION:  Amortization expense for the nine months ended June 30, 1999
was $1,569,000, an increase of $157,000 from the comparable prior period. The
increase was

                                       25
<PAGE>   29

primarily due to the additional goodwill resulting from the fiscal 1998
acquisitions, offset by $322,000 reduction in amortization expense resulting
from the exit of Waterlink's Bioclear business during the fourth quarter of
fiscal 1998.

     INTEREST EXPENSE:  Interest expense for the nine months ended June 30, 1999
was $5,092,000, an increase of $3,355,000 from the comparable prior period
primarily due to increased borrowings related to Waterlink's fiscal 1998
acquisitions.

     INCOME TAXES:  Waterlink recorded income taxes of $869,000 on a pre-tax
loss of $2,289,000 for the nine months ended June 30, 1999. This income tax
expense was recorded on its earnings outside the United States and in certain
states domestically. The effective income tax rate of 44.1% for the nine months
ended June 30, 1998 exceeded the United States federal statutory rate of 34% due
primarily to non-deductible goodwill amortization related to certain
acquisitions made by Waterlink as well as state and local income taxes.

LIQUIDITY AND CAPITAL RESOURCES

     Since its inception, Waterlink's primary sources of liquidity have been:

     - borrowings available under credit facilities

     - net proceeds from the sale of Waterlink's common and preferred stock

     - issuance of common stock and seller financing incurred in connection with
       Waterlink's completed acquisitions

     - cash flow from certain profitable acquisitions

     Historically, Waterlink's primary uses of capital have been:

     - the funding of its acquisition program

     - working capital requirements including the funding for growth at certain
       acquisitions

     - the funding required for certain under-performing acquisitions

     Waterlink does not currently anticipate making significant capital
investments in plant and equipment because of our efforts to partner with
vendors who manufacture most of the components used in our systems and
equipment.

     For the nine months ended June 30, 1999, net cash provided by operating
activities was $2,337,000. This positive cash flow, along with $519,000 of
proceeds from the sale of a building, were used to help fund purchases of
equipment totaling $1,470,000 and cash outlays related to the purchases of
businesses of $1,902,000.

     In the fourth quarter of fiscal 1998, Waterlink's board of directors
approved the 1999 plan. The 1999 plan provides for costs associated with the
exiting of certain facilities and employee termination costs. Costs associated
with this plan totaled $2,858,000 during fiscal 1998 and $1,487,000 for the nine
months ended June 30, 1999, of which approximately $1,169,000 remains reserved
for future payment at June 30, 1999. We expect to recognize additional special
charges associated with the 1999 plan of approximately $213,000 during the
remainder of fiscal 1999.

     Waterlink is in the process of selling and disposing of non-revenue
producing assets. A Waterlink-owned facility vacated during fiscal 1998 was sold
and the proceeds of $519,000 were received during January 1999. Waterlink is
also in the process of selling our land, building and equipment in Winnipeg,
Manitoba, Canada, the former site of our Bioclear

                                       26
<PAGE>   30

manufacturing facility. Based on the status of the sales process and Waterlink's
June 1999 decision regarding how to best dispose of the facility, Waterlink
further reduced the estimated net realizable value of these remaining assets
held for sale by $1,300,000 to approximately $1,000,000, and recorded this
change in accounting estimate during the quarter ended June 30, 1999.

     During fiscal 1998 Waterlink invested in Aquatec Water Systems,
Incorporated, a designer and manufacturer of specialized multi-chamber pumps for
the pure water industry, in the form of two $700,000 subordinated notes,
convertible into approximately 30% of the equity of Aquatec, together with other
stock purchase options. Waterlink reached an agreement to sell both notes at
their face value of $700,000 each plus interest to a group of investors.
Waterlink has received payment for one of the $700,000 notes and has received
$550,000 of the other note. Waterlink expects to collect the remaining balance
of $150,000 before September 30, 1999, the end of our fiscal year.

ACQUISITIONS

     Waterlink's current capital structure does not support an acquisition
program. Waterlink's intends to improve its capital structure through a
combination of improved operating performance and access to capital markets,
which we expect will enable us to resume our acquisition program. Acquisitions
are expected to play a strategic role in Waterlink's future to increase
competitiveness, spur revenue and earnings growth, and enhance our total
solutions capability. The timing, size and success of any acquisition effort and
the associated potential capital commitments are unpredictable at this time. As
a result of the specialty products division acquisition and the implementation
of our 1999 plan, our debt is in excess of our stockholders' equity and we bear
the risks associated with increased leverage.

     During the nine months ended June 30, 1999 Waterlink made additional
purchase consideration payments of $1,902,000 related to the achievement of
targeted operating results of two of our acquisitions. In addition, additional
purchase consideration of $500,000 in connection with one of Waterlink's
acquisitions had been earned and recorded as of June 30, 1999, and is expected
to be satisfied during this calendar year. These amounts have been recorded as
additional goodwill.

     Under the terms of certain of the purchase agreements, Waterlink may be
required to make additional purchase consideration payments of up to $1,224,000,
contingent upon the achievement of specified operating results through fiscal
2000. The payments that are expected to be required for meeting fiscal 1999 and
2000 targets are $224,000 and $1,000,000, respectively. Any additional purchase
consideration payments will be treated as additional goodwill for accounting
purposes.

CREDIT AVAILABILITY

     Waterlink's credit facilities are comprised of (1) an $87,000,000 domestic
facility with Bank of America National Trust & Savings Association as agent,
which expires on May 19, 2003 and (2) separate facilities aggregating
approximately $6,500,000 at three of its overseas subsidiaries. The credit
facilities will be utilized to primarily fund operating activities of Waterlink
and, to a lesser extent, fund future acquisitions.

     Effective June 29, 1999, Waterlink entered into an amendment of our
$87,000,000 domestic facility, which waives until October 8, 1999 certain
financial covenants that were not satisfied at June 30, 1999, assuming Waterlink
realizes not less than $700,000 of operating income on a monthly basis for the
remainder of fiscal 1999. As part
                                       27
<PAGE>   31

of this amendment, $2,600,000 of borrowings was made available to Waterlink as
the result of third party guarantees and the interest rate charged Waterlink was
increased by 50 basis points. In connection with assisting in the process of
improving our capital structure, these third party guarantees were provided by
Brantley Venture Partners III, L.P. in the amount of $2,300,000, and by the
three executive officers of Waterlink totaling $300,000.

     Waterlink granted the guarantors warrants to purchase, in the aggregate, up
to 283,637 shares of Waterlink common stock at an exercise price of $.01 per
share. Of the 283,637 warrants, 125,000 were issued at the time the guarantees
were issued and the remaining 158,637 warrants will be issued subject to
shareholder approval. The warrants are immediately exercisable and expire if
unexercised in five years. The number of warrants granted to each guarantor was
based on their proportionate share of the $2,600,000 in guarantees.

     Availability for future borrowings of $2,600,000 at June 30, 1999 under the
credit facilities is based on third party guarantees. Availability for future
borrowings may increase or decrease based on the pro forma operating performance
of Waterlink, the ability to raise additional capital to reduce indebtedness,
and the successful negotiation of amended terms and conditions of the $87
million domestic facility. Presently, Waterlink is exploring with certain
institutional investors financing alternatives, including the sale of equity
securities under this prospectus, part of the proceeds of which would be used
primarily to reduce indebtedness. No agreement to that effect has been reached
to date.

     In the event that the terms of the June 29, 1999 amendment are not met, we
are unable to raise additional capital to comply with the credit agreement, or
we are unable to negotiate a further amendment to the credit agreement, then
Waterlink would be in default under the terms of the credit agreement. If there
is an event of default the lenders could declare that all borrowings under the
credit agreement are immediately due and payable. If we are unable to repay
those amounts then the lenders could proceed to foreclose on their security
interest, which comprises substantially all of our assets.

     We are currently discussing with our lenders an additional amendment to the
credit agreement. If we are able to raise sufficient additional capital we
expect to amend the credit agreement to make additional funds available to us
and to continue the growth phase of the 1999 plan.

     Loans under the credit facilities bear interest at a designated variable
base rate plus spreads ranging from 0 to 75 basis points depending on a leverage
ratio of total consolidated indebtedness to Waterlink's earnings before
interest, taxes, depreciation and amortization. At Waterlink's option, the
credit facilities bear interest based on a designated London interbank offering
rate, or LIBOR, plus spreads ranging from 100 to 275 basis points, depending on
Waterlink's leverage ratio.

     The credit facilities restrict or prohibit Waterlink from taking many
actions, including paying dividends and incurring or assuming other indebtedness
or liens. The banks that participate in the credit facilities also must approve
most acquisitions. Waterlink's obligations under the credit facilities are
secured by liens on substantially all of Waterlink's domestic assets, including
equipment, inventory, accounts receivable and general intangibles and the pledge
of most of the stock of Waterlink's subsidiaries. Waterlink has guaranteed the
payment by our three overseas subsidiaries of their obligations under the
overseas facilities. The three overseas subsidiaries have given the lenders an
assurance that the subsidiaries would not pledge their assets to any other
party.

                                       28
<PAGE>   32

     Waterlink also has in place a $3,000,000 credit facility with Royal Bank of
Canada to fund Canadian working capital requirements including banker's
acceptances and letters of credit. Interest rates are negotiated on an
individual borrowing basis and are related to the Royal Bank of Canada's prime
rate. At June 30, 1999 the Canadian credit facility was fully utilized.
Borrowings under the Canadian credit facility are payable upon demand and are
guaranteed by the real and personal property of Waterlink's Bioclear facility.

     Waterlink believes that through the end of fiscal 1999, sufficient funds
for our working capital needs, additional cash requirements of the 1999 plan and
additional contingent consideration payments related to acquisitions will be
provided by:

     - future cash flow from operations

     - borrowings under its credit facilities

     - issuance of subordinated indebtedness, common stock, preferred stock and
       seller financing incurred in connection with future financings or
       acquisitions

     - the sale of certain non-revenue producing assets

     Before October 8, 1999 Waterlink intends to enter into an amendment to our
$87,000,000 domestic facility or enter into a new credit facility with other
lenders in order to meet our working capital requirements and to avoid being in
default on that date. The success of either action is dependent upon Waterlink's
operational performances, our ability to raise additional capital to reduce
indebtedness and the willingness of our senior lenders to agree to a
satisfactory amendment or our ability to finalize a new credit facility. While
we believe that we will be able to enter into a satisfactory amendment to our
domestic facility or a new credit facility to meet our requirements and avoid
default, if we are unable to do so, we would seek other sources of capital or
pursue other strategic alternatives.

MARKET RISK

     Waterlink's earnings are affected by changes in interest rates charged on
our domestic facility. During 1998, Waterlink entered into an interest rate swap
agreement with a major commercial bank to modify the interest characteristics of
its domestic facility. The agreement involves the exchange of amounts based on a
fixed rate of interest for an amount based on a LIBOR-based floating rate over
the life of the agreement without an exchange of the notional amount upon which
the payments are based. The agreement, which expires on December 30, 1999, fixes
Waterlink's LIBOR-based rate at 5.25% on a notional amount of $75,000,000.

     Waterlink also has exposure to currency rate fluctuations related primarily
to the purchases of inventory. Waterlink continues to utilize a limited number
of foreign exchange instruments, primarily forward contracts, to manage this
exposure.

YEAR 2000

     The year 2000 issue, as widely reported, could cause malfunctions in
certain computer-related applications with respect to dates on or after January
1, 2000. These malfunctions could relate to Information Technology, IT, or
non-IT environments. Due to Waterlink's decentralized IT environments,
individual assessments, in accordance with Waterlink's year 2000 program, have
been conducted at Waterlink's operating companies. Collectively, these
assessments indicate that Waterlink's exposure to this segment of the year 2000
issue is not significant as Waterlink does not extensively rely on IT systems
which require modification. Waterlink's externally developed system issues have
been assessed company-wide through inquiry of external vendors and testing
procedures where

                                       29
<PAGE>   33

necessary. The appropriate upgrades, if required, have been (or are scheduled to
be) attained in order to make these systems year 2000 compliant. Waterlink has
tested internally developed software systems where applicable and has developed
programs to make these systems year 2000 compliant. Testing of upgraded or
modified systems has begun at Waterlink's various operating units. Results of
these testing procedures, which are scheduled to be completed by the end of
fiscal 1999, are incomplete.

     The year 2000 program also addresses issues related to non-IT environments.
Collectively, these assessments indicate that Waterlink's exposure to this
segment of the year 2000 issue is not significant due to Waterlink's limited
manufacturing operations and related capital equipment needs. Waterlink's
operating equipment has been assessed through inquiry of external manufacturers
and internal testing procedures. Remediation efforts have begun where necessary.
Collectively, Waterlink intends to complete and test remediated assets by the
end of fiscal 1999.

     Waterlink's primary system interface with an external party involves its
banking institutions. Based on inquiries of its banking institutions, Waterlink
is not aware of any unresolved year 2000 issues. Further, due to Waterlink's
decentralized operations, individual assessments, in accordance with Waterlink's
year 2000 program, have been conducted at Waterlink's operating companies
regarding significant suppliers and subcontractors. These assessments, which are
not complete, have been executed primarily through inquiry of our various
suppliers and subcontractors. To date, Waterlink is not aware of any external
party with an unresolved year 2000 issue that would materially impact
Waterlink's operations and financial position. However, Waterlink has no means
of ensuring that external parties will be year 2000 compliant. The inability of
external parties to resolve their year 2000 issue in a timely manner could
impact Waterlink's operations and financial position. The effect of
non-compliance by external parties is not determinable.

     Waterlink has primarily utilized internal resources to assess, test,
remediate and implement software and equipment related to the year 2000. The
total cost of our year 2000 program, excluding employee salaries, is estimated
at $400,000, primarily attributable to software upgrades and modifications.
Waterlink has incurred approximately $325,000 related to the various phases of
its year 2000 program through June 30, 1999.

     We believe that we have a program established to resolve the year 2000
issue in a timely manner. Waterlink's year 2000 program has not been completed.
In the event Waterlink does not complete its remaining year 2000 procedures, we
believe under a worst case scenario, certain functions may be interrupted.
Waterlink does not have a formal contingency plan established if all phases of
its year 2000 program are not completed. However, appropriate actions, such as
interim manual information systems, will be instituted to mitigate such
interruption. In addition, disruptions in the economy generally resulting from
unresolved year 2000 issues could also materially adversely affect Waterlink.
The potential liability and loss of revenue from these issues is not
determinable.

IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS

     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income", which establishes standards for the reporting and display of
comprehensive income and its components. This statement is intended to address
the concerns of financial statement users for the increasing number of items
that bypass the income statement, such as foreign currency translation
adjustments. Waterlink adopted this statement on October 1, 1998.

                                       30
<PAGE>   34

     In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
an Enterprise and Related Information", which changes the way public companies
report segment information in annual financial statements. The statement also
requires public companies to report selected segment information in interim
financial reports to shareholders. The statement is effective for Waterlink's
annual reporting in fiscal 1999 and restatement of comparative information for
earlier years is required in the initial year of adoption. The implementation of
the 1999 plan will require Waterlink to present segmented industry information
upon adoption of SFAS No. 131.

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities", which provides a comprehensive and
consistent standard for the recognition and measurement of derivatives and
hedging activities. The statement will require, among other things, that all
derivatives be recorded on the balance sheet at fair value. In June 1999, the
FASB issued SFAS No. 137, "Accounting for Derivative Instruments and Hedging
Activities-Deferral of the Effective Date of FASB Statement No. 133", which
makes SFAS No. 133 effective for Waterlink beginning October 1, 2000. Waterlink
has not yet determined what the effect of adopting SFAS No. 133 will be on our
operations or financial position.

                                  OUR BUSINESS

GENERAL

     Waterlink is an international provider of integrated water purification and
wastewater treatment solutions, treating process water and wastewater for its
industrial customers, and drinking water and wastewater for its municipal
customers. Waterlink designs, assembles and sells water and wastewater treatment
products and provides related services to companies and municipalities to treat
their water and wastewater. Waterlink believes that its comprehensive range of
products and application engineering expertise enables it to produce single
source solutions demanded by its customers.

     Waterlink was incorporated in Delaware on December 7, 1994 to participate
in the consolidation of the highly fragmented water purification and wastewater
treatment industry. Waterlink grew rapidly through acquisitions from 1995
through 1998. To date Waterlink has made 13 acquisitions, targeting businesses
in two principal markets (wastewater and pure water treatment) and in two
geographic areas (United States and Europe).

DIVISIONAL FORMAT

     In September 1998, Waterlink, under the direction of its recently appointed
president and chief executive officer, announced its 1999 Strategic Operating
Plan. The 1999 plan provides for a divisional format for efficient centers of
product expertise and geographic experience, to better serve Waterlink's
customers and independent marketing representatives. Under the 1999 plan,
Waterlink reorganized from a holding company that completed 13 acquisitions with
23 direct and indirect operating companies into five integrated divisions. The
divisions are:

     - the Biological Wastewater Treatment Division

     - the Separations Division

     - the Pure Water Division

     - the Specialty Products Division

     - the European Water and Wastewater Division

BIOLOGICAL WASTEWATER TREATMENT DIVISION

     The biological wastewater treatment division provides products and
processes treating municipal and industrial wastewater by various biological
based methods. This division furnishes products and processes that can be
incorporated into integrated systems or sold individually. Its products include
aeration systems, which treat wastewater with air and/or process water that is
pumped at high pressures through a series of jet nozzles, resulting in highly
efficient oxygen transfers and mixing activity to separate waste. These systems
are sold separately for use in industrial biological treatment plants and many
other uses, including for underdeveloped countries where land intensive, lagoon
treatment processes are widely accepted. In addition, these systems can be
integrated with other processes for more complete biological treatment
solutions. Waterlink's patented Aero-Mod Sequox(TM) nutrient removal process
uses aeration to increase biological activity for removing unwanted pollutants
from the water.

     The biological wastewater treatment division also designs and manufactures
industrial separation systems using various technologies used to separate solids
from industrial
                                       32

coolants. The division markets its products and processes through both direct
sales offices and independent sales representatives located predominantly in
North and South America, the United Kingdom, Ireland and Asia. For the nine
months ended June 30, 1999, net sales for this division were approximately $14.1
million.

SEPARATIONS DIVISION

     This division sells equipment and engineered systems employing physical and
chemical separation technology. Its markets are municipal water and wastewater
as well as industrial process water and wastewater. The division combines the
technology offerings of industry leading product lines. The separations
division's products include the following:

     - Hycor(R) screening, conveying, dewatering and screenings/grit washing
       equipment. Dewatering is the process of reducing or eliminating moisture
       content. These products operate on the principle of liquid/solid gravity
       separation and are used to improve water and wastewater processes,
       minimize waste, reduce disposal volumes and provide for water recovery
       and reuse.

     - Lanco Environmental(TM) filter presses, clarifiers and sludge dryers.
       Primarily serving the industrial market, this equipment is designed for
       the efficient dewatering of effluent and sludges from specialized
       industrial processes.

     - Great Lake Environmental(R) oil/water separations, inclined plate
       clarifiers and dissolved air flotation systems. With its broad industrial
       customer base, this product line offers a wide range of equipment from
       the basic separation and removal of oil droplets from water to systems
       which remove suspended solids and emulsified oil from continuous flows.

     - Nordic Water(TM) continuous sand filters, inclined plate clarifiers and
       sludge removal equipment. These products offer a wide range of
       capabilities including tertiary polishing filters, used to remove fine
       particles, nitrates and phosphates in wastewater, solutions for high
       turbidity, or cloudiness, in municipal water treatment, advanced settling
       technology and sophisticated sludge removal equipment.

     The separations division sells its products and systems primarily in North
America through a network of independent manufacturers representatives. For the
nine months ended June 30, 1999, net sales for the division were approximately
$25.6 million.

PURE WATER DIVISION

     The pure water division sells products and solutions to the residential,
municipal and industrial water and process water markets through our Waterlink
Technologies, Inc. and C'treat Offshore, Inc. companies.

     Waterlink Technologies is an international provider of membrane based
solutions focusing on:

     - membrane technology with standard reverse osmosis system solutions which
       can treat tap water to sea water for the production of high purity water

     - nanofiltration systems, which can be used to decolor, soften and remove
       harmful pathogenic organisms

     - desalination systems for the purification of sea water to drinking water
       for resorts, municipal and governmental installations

                                       33
<PAGE>   37

     - custom engineered microfiltration systems that can be used for the
       clarification and removal of harmful organisms from surface water as well
       as pre-treatment for other membrane technology in wastewater applications

     - custom designed ultra pure water treatment systems for the power,
       electronic and pharmaceutical industries

     - the manufacture of pleated membrane sediment filtration cartridges which
       are used for removal of suspended solids

     - the distribution of other major lines of filter housings, filters and
       components

     C'treat is a provider of reverse osmosis desalination equipment and
services to the worldwide energy industry. C'treat equipment economically and
reliably provides fresh water for offshore drilling rigs and production
platforms. C'treat enjoys a significant market presence through a sales
organization that includes representatives and technical licensees in 12
countries. For the nine months ended June 30, 1999, net sales for this division
were approximately $11.5 million.

SPECIALTY PRODUCTS DIVISION

     Waterlink's specialty products division and its predecessors have
specialized in the development and production of highly sophisticated activated
carbons for more than 80 years. Activated carbon is used to purify air, water
and gases by retaining impurities in carbon granules. The division is a
worldwide supplier of activated carbon for liquid, air and gas filtration
systems and is a leading manufacturer of specialty impregnated carbons used in
applications where the capacity of activated carbons can be significantly
increased. A full range of activated carbons manufactured from coconut shell,
coal, wood, along with other adsorbents such as modified clay media, bone char,
and anthracite are offered for use in:

     - adsorption equipment, both standard and custom configurations, primarily
       for separation of solvents from air

     - bioreactors and bioscrubbers in which contaminants are destroyed using
       biological microbes

     - corrosive gas control systems to protect expensive electronic operated
       controls

     - distillation equipment for separation applications

     - systems that control emissions from volatile organic compounds

     - area filtration systems for the removal of both vapor phase and
       particulate contaminants

     - indoor air quality systems

     - odor control systems

     - soil vapor extraction systems

     - solvent recovery systems engineered and installed on a turn-key basis, to
       recover valuable solvents

     This division's products and systems are sold worldwide using a combination
of direct sales and sales representatives. For the nine months ended June 30,
1999, net sales for this division were approximately $42.1 million.

                                       34

EUROPEAN WATER AND WASTEWATER DIVISION

     The European water and wastewater division provides products and systems
similar to the separations division but focusing specifically on the European,
African and Asian municipal and industrial markets.

     The European water and wastewater division, with principal locations in
Sweden, Germany and the United Kingdom, offers its products under various
proprietary names, including:

     - Dynasand(TM) continuous sand filters

     - Lamella(TM) separators

     - Zickert(TM) bottom scrapers

     - Noxon(TM) centrifuges

     - MEVA(TM) fine screens

The products are sold separately or as an engineered turn-key solution. For the
nine months ended June 30, 1999, net sales for the division were approximately
$35.6 million.

OPERATING AND SALES STRATEGY

     Waterlink has adopted a decentralized approach to the operational
management of our divisions. While functions such as strategic planning,
financial reporting, treasury, communications and risk management are
centralized in Waterlink's corporate headquarters, local management at each of
our five divisions is primarily responsible for the day-to-day operation of the
division's business. Waterlink also provides our divisions with financial
resources, management expertise, and customer and market access, which would be
unavailable to each division individually. Waterlink expects to realize
significant improvement in internal growth rates due to increased marketing
efforts and the opportunities to "cross-sell" products. As customers
increasingly seek to reduce their vendor base, outsource their non-core tasks
and find integrated solutions, the ability of each of our divisions to offer the
complementary equipment and services of other divisions increases the
competitiveness of Waterlink. For example, the separations division can team
with the pure water division and the biological division to offer both pure
water and wastewater solutions to a customer. Additionally, Waterlink's
design/build capabilities allow us to design systems that utilize a broad array
of Waterlink's products and provide opportunities for our specialty products
division. Waterlink also experiences cross-selling opportunities from a
geographic and customer standpoint. For example, our European water and
wastewater division has introduced our other divisions' systems, equipment and
services into the European market. Likewise, we have introduced the European
water and wastewater division's systems, equipment and services into our
domestic market.

     We sell our systems, equipment and services primarily through approximately
80 direct sales personnel and approximately 250 independent sales organizations.
Waterlink also sells through licensees, principally in the Asia-Pacific region
as well as in Europe. To a lesser extent, Waterlink sells through water
treatment distributors, which take title to equipment for resale to the
end-user. Waterlink 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 Waterlink's direct sales force, which has greater
technical and product knowledge, to

                                       35
<PAGE>   39

complete the sale and service the customer. Waterlink's direct sales force
generally plays a more primary role in sales of Waterlink's design/build
solutions.

     While we have received contract awards in excess of $5 million, Waterlink
is focusing its marketing efforts on contract awards of up to approximately $4
million. We believe that competition is more fierce for larger contract awards
and the timing of these awards is more unpredictable.

     To help facilitate revenue growth, and better serve our customer base,
Waterlink has formed a centralized marketing and sales team of three individuals
whose primary focus is to position Waterlink in the marketplace as an important
independent solution provider for municipal and industrial water and wastewater
requirements. This centralized sales and marketing approach will also utilize
technical divisional expertise and the market knowledge of our geographically
based independent representatives to focus on market opportunities. One of these
opportunities appears to be a national accounts program through which we intend
to provide water and wastewater solutions to major engineering and industrial
companies. Waterlink's centralized marketing and sales team is preparing to
focus initially on engineering and construction firms and key industrial
accounts in the food and beverage and pulp and paper industry.

     A representative from each of our divisions, along with Waterlink's
executive officers and other key employees, form Waterlink's senior management
team, which meets on a frequent basis to facilitate the interchange of
information and enhance cross-selling opportunities.

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. Waterlink 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 Waterlink. We believe 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 to set pricing are
often primary considerations. Waterlink 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.

     We believe that new entrants will play a significant role in the United
States municipal markets as privatization contracts for water and wastewater
concessions are expected to grow in size and importance. We believe that as an
independent supplier of water and wastewater solutions and equipment to these
service providers, we can provide a sound alternative to our competition.

     Waterlink's primary competitors include operating subsidiaries of Vivendi
formally known as Compagnie Generale des Eaux and its recent acquisition of U.S.
Filter Corporation, Suez de Lyonaise des Eaux, Calgon Carbon Corporation;
Parkson Corporation; Ionics, Incorporated; Alpha Laval and Humbolt KHD.

ACQUISITION STRATEGY

     In order to achieve its objective of becoming a leading international
provider of integrated water purification and wastewater treatment solutions,
Waterlink has in the past pursued an aggressive acquisition-based growth
program.

     Waterlink's acquisition strategy has been curtailed during fiscal 1999 due
to the effort required to complete the 1999 plan and as a result of Waterlink's
leverage. Proceeds from this offering are not expected to be utilized for
acquisition activity.

     Waterlink intends to continue to use various combinations of its common
stock, cash and notes as consideration for future considerations. The
consideration for each future acquisition will vary on a case-by-case basis
depending on Waterlink's operating performance and the historic operating
results and future prospects of the business to be acquired. Waterlink intends
to finance future acquisitions through funds provided by operations and if
available, bank borrowings and proceeds of future equity and debt financing.

CUSTOMERS

     Waterlink 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. Waterlink has a diverse customer base, with
no customer representing 10% or more of Waterlink's sales for the nine months
ended June 30, 1999.

     Waterlink'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, printing, automotive and other heavy
manufacturing industries. For the nine months ended June 30, 1999 approximately
74.1% of Waterlink's 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. Waterlink utilizes specialized distribution channels
to service the municipal market and is skilled at participating in the municipal
bidding process. Waterlink focuses its efforts on smaller municipal projects
which Waterlink believes its product lines are best suited to serve. Waterlink
believes that the municipal business is important to its overall success because
of its large market size. For the nine months ended June 30, 1999 approximately
25.9% of Waterlink's net sales were derived from municipal sales.

BACKLOG

     Total backlog as of June 30, 1999 was $46.0 million as compared to total
backlog of $44.5 million at September 30, 1998. Waterlink had a backlog,
consisting of written purchase orders for capital goods equipment of $39.8
million as of June 30, 1999 as compared to $38.1 million as of September 30,
1998. In addition, at June 30, 1999, Waterlink had $6.2 million of firm
commitments to purchase recurring revenue products from its specialty products
division as compared to $6.4 million as of September 30, 1998. Waterlink expects
that virtually all of the backlog at the beginning of a fiscal year will be
filled during that year. Backlog, and therefore sales, 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 Waterlink's backlog

                                       37
<PAGE>   41

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 industry practices, we generally offer 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 our customers, Waterlink is sometimes required to guarantee that our
products or services will attain specified levels of quality or performance. If
a product fails to perform according to a warranty, or a project fails to attain
the guaranteed level of quality, and if we are unable to effect a satisfactory
replacement or cure within the prescribed period of time, Waterlink 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, Waterlink 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 Waterlink'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. Waterlink's systems are
fabricated from these materials and assembled together with products bought from
other companies to form an integrated system. In addition, the specialty
products division is dependent on the importation of coconut shell carbon from
the Asia and the supply of coal based carbon from domestic and Asian sources.
Waterlink is not dependent upon any single supplier, and if any supplier were to
become unable to perform, Waterlink believes a substitute source could readily
be found. Waterlink has generally been able to pass on price increases for raw
materials and components to its customers. Waterlink 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 Waterlink.

     Many of the countries in which Waterlink operates or in which our customers
are located, including the United States, 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 Waterlink. 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 country, Waterlink 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 Waterlink.

                                       38
<PAGE>   42

     Any changes in applicable environmental standards and requirements or their
enforcement may affect the operations of Waterlink by imposing additional
regulatory compliance costs on Waterlink's customers, requiring the modification
of and/or affecting the market for Waterlink's solutions, systems and equipment.
To the extent that demand for Waterlink's solutions, systems and equipment is
created by the need to comply with these enhanced standards and requirements or
their enforcement, any modification of the standards and requirements or their
enforcement may reduce demand, thereby adversely affecting Waterlink's business
prospects. Conversely, changes in applicable environmental laws imposing
additional regulatory compliance standards and requirements or causing stricter
enforcement of these laws or regulations could increase the demand for
Waterlink's systems, equipment and services.

PATENTS, TRADEMARKS AND LICENSES

     We currently own a number of United States and foreign patents, and
registrations for United States service marks and trademarks. While each is of
value, Waterlink generally does not consider any of them to be material to our
business, although, as Waterlink has grown and its presence has been extended,
our Waterlink(SM) mark has become more widely known and the goodwill associated
with it has increased.

EMPLOYEES

     At June 30, 1999, Waterlink had approximately 638 employees at our various
locations. Approximately 51 people are covered under collective bargaining
agreements in the United States. All of Waterlink's hourly employees in Europe
are covered by collective bargaining agreements. We believe that our
relationship with our employees is good.

PROPERTIES

     We lease our corporate offices, consisting of approximately 7,000 square
feet located in Canton. In addition, our subsidiaries lease facilities for
office space and manufacturing in the United States in Santa Fe Springs,
California; Clearwater and West Palm Beach, Florida; Lake Bluff and Addison,
Illinois; Manhattan, Kansas; Fall River, Massachusetts; Grand Rapids, Michigan;
Sparks, Nevada; and The Woodlands, Texas; and outside the United States in
Holstebro, Denmark; Lancashire, England; Vanda, Finland; Neuss-Grimlinghausen,
Germany; and Mariestad, Frolunda, Kungsbacka, and Nynashamn, Sweden; and own
facilities for office space and manufacturing in Columbus, Ohio; Winnipeg,
Manitoba, Canada; and Fjaras, Sweden. The expiration dates for these leases
range from August 1999 to March 2011.

     We believe that each of our facilities is in good condition and will
continue to remain suitable for its current purpose. We may add improvements to
the properties listed above. We anticipate using our properties for purposes
consistent with their present use. In the event any of the facilities becomes
unavailable upon termination of the existing lease, we believe we would be able
to find a suitable alternative facility without any significant adverse impact
to us or our operations. We believe our properties are adequately covered by
insurance.

LEGAL PROCEEDINGS

     From time to time in the normal course of our business, we become a party
to litigation. Most of this litigation involves claims for personal or
employment related injury or property damage incurred in connection with our
operations. We are not a party to any material litigation and believe that none
of our litigation will have a material adverse effect on our business or
financial results.

COMPOSITION OF OUR BOARD OF DIRECTORS AND COMMITTEES

     Our board of directors is divided into three classes. Each class consists,
as nearly as possible, of one-third of the whole number of the board of
directors. Directors for each class are elected at the annual meeting of
stockholders held in the year in which the term for such class expires. Upon
election, directors will serve thereafter for three years, and hold office until
their successors are elected and qualified. There are currently six members of
the board of directors. The term of Class I directors will expire in 2001, the
term of Class II directors in 2002 and the term of Class III directors in 2000.

     Our board of directors has three standing committees: an audit committee, a
compensation committee and a nominating committee.

     During the fiscal year ended September 30, 1998, the board held five
meetings. Messrs. John R. Miller, Rollin S. Reiter and Dr. Paul M. Sutton
(Chairman) serve on the audit committee, Messrs. John R. Miller, Robert P.
Pinkas, Rollin S. Reiter (Chairman) and Dr. Paul M. Sutton serve on the
compensation committee and Messrs. John R. Miller, Robert P. Pinkas and Dr. Paul
M. Sutton (Chairman) serve on the nominating committee. Each of the directors
attended 75% or more of all meetings of the board and of its committees of which
he was a member.

AUDIT COMMITTEE

     The audit committee acts as a liaison between Waterlink's independent
auditors and the board of directors, reviews the scope of the annual audit and
the management letter associated therewith, reviews Waterlink's annual and
quarterly financial statements and reviews the sufficiency of Waterlink's
internal accounting controls. The audit committee held two meetings during
fiscal 1998.

COMPENSATION COMMITTEE

     The general functions of the compensation committee include approval (or
recommendation to the board of directors) of the compensation arrangements for
senior management, directors and other key employees, review of benefit plans in
which officers

                                       41
<PAGE>   45

and directors are eligible to participate and periodic review of the equity
compensation plans of Waterlink and the grants under such plans. The
compensation committee administers the 1997 omnibus incentive plan, the 1995
stock option plan, the 1997 non-employee director stock option plan and the
employee stock purchase plan. The compensation committee held two meetings
during fiscal 1998.

NOMINATING COMMITTEE

     The nominating committee makes recommendations concerning the organization,
size and composition of the board of directors and its committees, proposes
nominees for election to the board of directors and its committees and considers
the qualifications, compensation and retirement of directors. The nominating
committee did not meet during fiscal 1998. The nominating committee will
consider nominations of persons for election as directors that are submitted by
stockholders in writing in accordance with requirements set forth in our
By-Laws.

DIRECTOR REMUNERATION

     Directors who are employees of Waterlink receive no compensation, as such,
for service as members of the board of directors or any committees of the board
of directors.

     Waterlink compensates only those directors who are not employees of
Waterlink for their participation as directors. They receive an annual retainer
of $10,000. In addition, they receive $750 for each meeting of the board of
directors (in excess of the four regularly scheduled meetings) or any committee
of the board attended by them (other than meetings of any committee on a day on
which the board also meets), and $250 for each additional telephonic meeting of
the board of directors or any committee of the board of directors. All directors
are reimbursed for out of pocket expenses incurred in attending meetings of the
board of directors or committees and for other expenses incurred in their
capacity as directors.

     In addition, directors who are not Waterlink employees receive for each
year of service on the board of directors, options under our 1997 non-employee
director stock option plan. The per share exercise price of options granted
under the director plan is the fair market value of the common stock on the date
of grant. The exercise price for these options 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. Waterlink may establish "cashless exercise"
procedures, to allow a director to exercise an option and arrange for a
simultaneous sale of the underlying common stock, with the exercise price being
paid from the proceeds of that sale. Options granted under the director plan
will expire ten years after the date of grant. Of the options, 25% may be
exercised after one year from the date of grant, 50% after two years, 75% after
three years and 100% after four years.

     Messrs. Miller, Reiter and Sutton were each granted an option to purchase
3,000 shares of common stock in connection with his election to the board of
directors. In addition, on May 23 of each year, the anniversary of the date the
director plan became effective, each non-employee director who has served as a
director for at least six months is automatically granted an option to purchase
5,000 shares of common stock.

     The director plan is administered by Waterlink's compensation committee.
Since the principal terms of the option grants are specified in the director
plan, the compensation committee has no discretion to select which directors
receive options, the number of shares of common stock subject to options or the
exercise price of options.

     During fiscal 1998 Waterlink paid $3,000 to Dr. Paul M. Sutton, a director,
for consulting services he performed.

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

(1) The board elected Mr. King to be our president and chief executive officer
    effective June 8, 1998. Salary and other compensation for 1998 represent
    amounts from June 8, 1998 through September 30, 1998. For terms of Mr.
    King's compensation, see "Employment Agreements," below.

(2) Effective June 5, 1998, Mr. Ross resigned as our president and chief
    executive officer. The amounts shown as salary and bonus do not reflect
    severance compensation paid to Mr. Ross during 1998 and described in
    footnote 9 below.

(3) In January 1998 bonus payments were made which represent deferred payments
    in connection with our initial public offering. No other bonus amounts were
    earned or paid to these individuals during fiscal 1998.

(4) Mr. King's employment agreement provided for a bonus of $50,000 upon
    signing. No other bonus amount was earned by or paid to Mr. King during
    fiscal 1998.

(5) Represents $1,050,000 of gross-up payment for tax liabilities incurred by
    Mr. Savastano upon exercise of the non-qualified stock options described in
    footnote 6, below, which was paid to Mr. Savastano pursuant to his 1994
    employment agreement with Waterlink.

(6) The amount shown represents compensation related to the exercise of 100,000
    non-qualified stock options received by Mr. Savastano pursuant to the terms
    of his 1994 employment agreement. The options were exercisable upon
    consummation of our initial public offering. The compensatory amount was
    determined by multiplying the

                                       43
<PAGE>   47

    number of options exercised by the difference between the market value at
    the date of exercise ($16.6875) and the exercise price of $.10 per share.

(7) This represents Waterlink's "match" payment relating to our 401(k) Plan.

(8) This represents salary from January 1, 1997, the date Mr. Vantusko began
    working for us.

(9) This represents payments of $130,000 made in accordance with Mr. Ross'
    employment agreement of May 23, 1997 and with the agreement entered into in
    June 1998 in connection with his resignation and $2,791 which represents
    Waterlink's "match" payment relating to our 401(k) Plan.

STOCK OPTION GRANTS

     The following table designates each grant of stock options made to the
Named Executive Officers during fiscal 1998. The per share exercise price of
options granted under our stock option plans is the fair market value of the
common stock on the date of grant. Waterlink has not yet granted stock
appreciation rights, or SARs. Amounts under the column heading "Potential
Realizable Value..." represent hypothetical gains that could be achieve for the
options if exercised at the end of the option term. The 5% and 10% assumed
annual rates of compounded stock price appreciation are mandated by the rules of
the SEC and do not represent our estimate or projection of future common stock
price growth. These amounts represent assumed rates of appreciation in the value
of our common stock from the fair market value on the date of grant. Actual
gains, if any, are dependent on the actual future performance of our common
stock which will benefit all stockholders.

STOCK OPTION EXERCISES

     The following table describes exercises of stock options during fiscal 1998
by each of the Named Executive Officers and their stock options outstanding as
of September 30, 1998. Waterlink has not granted stock appreciation rights. None
of the outstanding stock options are "in-the-money" since the exercise price of
all options are in excess of the market price for common stock on September 30,
1998.

EMPLOYMENT AGREEMENTS

     Mr. Savastano entered into an employment agreement with Waterlink in 1997
which provides for him to serve as chairman of the board for an initial term of
three years subject to automatic one-year extensions on each anniversary of the
agreement until mandatory retirement at age 65. He is paid an annual base salary
of $240,000. Mr. Savastano participates in Waterlink's annual incentive bonus
plan which entitles him to earn annually an amount ranging from zero to 150% of
his base salary if performance goals established by the board of directors are
achieved. If Mr. Savastano's employment is terminated without cause or if he
terminates his employment for good cause, he will receive an amount equal to the
present value of twice the sum of his base salary in effect when terminated and
the annual bonus paid to him for that fiscal year if calculable, and if not
calculable, then the bonus paid to him with respect to the prior fiscal year,
except during fiscal 1999, during which the annual bonus paid is deemed to be
equal to his base salary. If the payment is as a result of a change of control
and the termination occurs within one year of the change of control, the amount
payable to Mr. Savastano will be paid in a lump sum. In either event, if the
amounts payable to Mr. Savastano are "excess parachute payments" for federal tax
purposes, Mr. Savastano will be paid an additional amount to offset any taxes
payable with respect to the excess parachute payment and the additional payment.
He is also restricted from competing with Waterlink during the term of his
agreement and for 24 months following its termination. If a change of control of
Waterlink occurs during fiscal 1999 and Mr. Savastano had his employment
terminated without cause or he terminated his employment for good cause, he
would have been entitled to a payment of $1,025,000.

     Mr. King entered into an employment agreement with Waterlink in 1998 which
provided for him to serve as president and chief executive officer for an
initial term of three years subject to automatic one-year extensions on each
anniversary of the agreement until mandatory retirement at age 65. He is paid an
initial annual base salary of $300,000. Mr. King participates in Waterlink's
annual incentive bonus plan which entitles him to earn annually an amount
ranging from zero to 150% of his base salary if performance goals established by
the board of directors are achieved. He was also paid a $50,000 signing bonus.
If Mr. King's employment is terminated without cause or if he terminates his
employment for good cause, he will receive an amount equal to the present value
of one

                                       45
<PAGE>   49

and one-half times the sum of his base salary in effect when terminated and the
annual bonus paid to him with respect to that fiscal year if termination occurs
after the first four months of the fiscal year, and if termination occurs during
the first four months of a fiscal year, then the bonus, if any, paid to him with
respect to the fiscal year immediately preceding the year in which his
employment was terminated, except during fiscal 1999, during which the annual
bonus paid is deemed to be equal to his base salary. If any of the payments
payable to Mr. King under these circumstances are "excess parachute payments"
for federal tax purposes, Mr. King is to be paid an additional amount to offset
any tax payable with respect to the excess parachute payment and the additional
payment. He is also restricted from competing with Waterlink during the term of
his agreement and for 18 months following its termination. If a change of
control of Waterlink occurs during fiscal 1999 and Mr. King had his employment
terminated without cause or he terminated his employment for good cause, he
would have been entitled to a payment of $950,000. Mr. King was granted options
to purchase 400,000 shares of common stock at $7.625, which was then the fair
value. Those options vest in four equal installments beginning on May 21, 1999
subject to acceleration.

     Mr. Vantusko entered into an agreement with Waterlink in 1997 which
provides for him to serve as chief financial officer for initial terms of three
years subject to automatic one-year extensions on each anniversary of the
agreement. He was paid an annual base salary of $150,000. Mr. Vantusko
participates in Waterlink's annual incentive plan which entitles him to earn
annually an amount ranging from zero to 150% of his base salary if performance
goals established by the board of directors are achieved. If Mr. Vantusko's
employment is terminated without cause or if he terminates his employment for
good cause, he will receive an amount equal to the sum of his base salary in
effect when terminated and the annual bonus paid to him for that fiscal year if
calculable, and if not calculable, then the bonus paid to him with respect to
the prior fiscal year, except during fiscal 1999, during which the annual bonus
paid is deemed to be equal to his base salary. He is also restricted from
competing with Waterlink during the term of his agreement and for 12 months
following its termination. If a change of control of Waterlink occurs during
fiscal 1999 and Mr. Vantusko had his employment terminated without cause or he
terminated his employment for good cause, he would have been entitled to a
payment of $425,000. In 1997, Mr. Vantusko was granted options to purchase
100,000 shares of common stock at $11.00 per share, the initial offering price
of the common stock sold in our initial public offering. This option vests in
four equal annual installments beginning on May 23, 1998, subject to
acceleration. Effective April 1, 1999, Mr. Vantusko's annual base salary was
increased to $200,000.

     Chet Ross entered into an agreement with Waterlink to resign his employment
in June, 1998. Mr. Ross had served as president and chief executive officer
since 1995. Pursuant to the agreement, Mr. Ross's employment terminated on June
5, 1998 at which time he also resigned as a director. Mr. Ross will receive
$780,000 payable in 48 equal semi-annual installments. He also retained for up
to two years standard executive employee medical and similar benefits. Stock
options to purchase 300,000 shares of common stock granted to him in May 1997

BENEFIT PLANS

     Waterlink currently has several stock option plans including our omnibus
incentive plan, 1995 stock option plan, employee stock purchase plan and 1997
non-employee director stock option plan. Our omnibus incentive plan, 1995 stock
option plan, stock purchase plan and director plan are intended to encourage
ownership of common stock by directors, officers and other key employees and
advisors of Waterlink, to encourage their continued employment with us and to
provide them with additional incentives to promote our success. Each of the
plans are administered by the compensation committee of the board of directors.
The compensation committee has the full power and authority, subject to the
provisions of each plan, to designate participants, grant awards and determine
the terms of all awards. Generally, all awards granted are subject to adjustment
upon a recapitalization, stock split, stock dividend, merger, reorganization or
other similar event affecting the common stock, subject to the terms of each
plan. Awards are not transferable, other than by will or the laws of descent and
distribution or, in certain circumstances, pursuant to a qualified domestic
relations order. An award may be exercised only by the holder or the holder's
representative in the event of death or disability. The board of directors may
amend each of the plans, but no amendment without the approval of the
stockholders may be made if stockholder approval is required under applicable
law. Additionally, no amendment may impair any rights of any holder of an award
previously granted under any plan without the holder's consent.

THE OMNIBUS INCENTIVE PLAN

     GENERAL INFORMATION.  Our omnibus incentive plan provides for compensatory
equity based awards. There are reserved for issuance an aggregate of up to
5,000,000 shares of common stock, or a lesser number calculated based upon a
formula using the number of awards granted under other benefit plans. 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 was approved by our board of directors and stockholders in May 1997, and
again by our stockholders in January 1998 and will terminate on the tenth
anniversary of the date of approval by our board of directors.

     STOCK AWARDS.  Our 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 Waterlink.

     SARS.  Upon exercising an SAR, the holder will be paid 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. We may, at our 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 (a) an aggregate payment by us during any fiscal year upon the
exercise of SARs exceed $100,000, or (b) a holder of an SAR, who is also an
employee of Waterlink or our 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.

                                       47
<PAGE>   51

     STOCK OPTIONS.  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 as a performance award. Upon
the 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. Upon the exercise of an option, the option holder will pay to us
the exercise price plus the amount of the required Federal and state withholding
taxes, if any.

THE 1995 STOCK OPTION PLAN

     GENERAL INFORMATION.  Our 1995 stock option plan authorizes the grant to
officers, key employees, and directors of awards consisting of incentive stock
options and non-qualified stock options. There are 1,600,000 shares of common
stock reserved for issuance under the 1995 stock option plan. As of July 31,
1999, options for 1,008,075 shares were outstanding, options for 465,000 shares
had been granted and exercised, and options for 126,925 shares were unissued.

     Our 1995 stock option plan terminates on February 1, 2005, although the
terms of any award may be amended in accordance with the 1995 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 1995 stock option plan continue in full force
and effect according to the terms and conditions of the award and the 1995 stock
option plan.

     STOCK OPTIONS.  Our compensation 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. 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 Waterlink or our subsidiaries 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. The option price per share of any non-qualified stock option is
determined by the compensation committee on the date the option is granted.
Options granted are exercisable for a term of not more than ten years from the
date of grant.

THE EMPLOYEE STOCK PURCHASE PLAN

     GENERAL INFORMATION.  Except as discussed below, employees are eligible to
participate in the stock purchase plan if they have been employed by Waterlink
or any of our subsidiaries for at least six months and who customarily work more
than 20 hours per week and five months per calendar year. 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 will terminate ten years from the date of adoption, and an option shall not
be granted under the stock purchase 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. As of July 31, 1999, 42,384 shares of common stock were purchased
pursuant to the stock purchase plan. Our stock purchase plan was approved by the
board of directors and stockholders in May 1997 and again by the stockholders in
January 1998.

                                       48
<PAGE>   52

     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 employees to whom offerings will be made, 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 and the
period pursuant to which installment obligations of the option price must be
paid.

     TERMS OF OFFERINGS.  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, at a price
determined by the compensation committee. These options will be automatically
exercised 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. 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 Waterlink or our subsidiaries, after taking into account certain
attribution rules. The subscription period and purchase period of any offering
made under the stock purchase plan may not together exceed 27 months.

     Subject to limitations set forth in the stock purchase plan, an employee is
permitted, at any time prior to the end of the purchase period, 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 us 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.

     In the case of an unusual corporate event such as liquidation, merger,
reorganization, or other business combination, acquisition or change in control
of Waterlink through a tender offer or otherwise, the board of directors 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.

1997 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

     GENERAL INFORMATION.  Our 1997 non-employee director stock option plan is
intended to encourage our non-employee directors 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 our continued success
and growth. 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 became effective
as of June 27, 1997 and will terminate ten years from that date. Our director
plan was approved by the board of directors and stockholders in May 1997.

     The director plan is 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.

                                       49
<PAGE>   53

     TERMS OF OPTIONS.  Each non-employee director who becomes a member of the
board of directors 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 became effective, each of our then non-employee directors who has
served as a director for at least six 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. Options granted under the director plan will
expire ten years after the date of grant, subject to earlier termination, and
vest equally over a period of four years.

     In the event that a director ceases to be a member of the board of
directors, 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 of directors, at any time
within three months after he or she ceases to be a member of the board of
directors, 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 of directors, or
within three months after he or she ceases to be a member of the board of
directors, 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, a director would be entitled to exercise the
option in full, but such option would terminate 90 days after the change in
control.

                             COMMON STOCK OWNERSHIP

     The following table sets forth the beneficial ownership of our common stock
as of July 31, 1999 by our executive officers of Waterlink, each of our
directors of Waterlink and all of our executive officers and directors of
Waterlink as a group, as well as by each person known by Waterlink to be the
beneficial owner of more than 5% of common stock. Beneficial ownership includes
shares of common stock subject to options, warrants, rights, or similar
obligations exercisable within 60 days of the date of determination for purposes
of computing the percentage of the person or group holding such options or
warrants. Except as noted, each stockholder has sole voting power and sole
investment power with respect to all shares beneficially owned by that
stockholder. The columns under the heading "Ownership After This Offering"
reflect the beneficial ownership of common stock as of July 31, 1999, modified
to include the additional beneficial ownership anticipated from this offering.
The percentage computations are based on 12,635,861 shares currently outstanding
and 18,935,861 outstanding as modified to include the shares anticipated to be
issued in this offering. An asterisk means ownership of less than one percent.

     Our board of directors has the authority, without any further vote or
action by the stockholders, to issue up to 10,000,000 shares of preferred stock
from time to time in one or more series and to fix the number of shares,
designations, rights, voting powers, preferences and limitations of that
preferred stock, including 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:

     - restrict common stock dividends if preferred stock dividends have not
       been paid;

     - 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

     - prevent current holders of common stock from participating in the
       distribution of Waterlink's assets upon liquidation until any liquidation
       preferences granted to holders of preferred stock are satisfied.

                                       54
<PAGE>   58

     In addition, the issuance of preferred stock may discourage bids for the
common stock at a premium over the market price and could have a material
adverse effect on the market value of the common stock. Our 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

     Pursuant to the terms of a registration rights agreement among us and some
of our stockholders, holders of approximately 4,637,573 shares of common stock
or securities exercisable for common stock may require us to register their
shares of common stock under the Securities Act. These stockholders included
Theodore F. Savastano, our chairman of the board, and Brantley Venture Partners
III, L.P., River Cities Capital Fund Limited Partnership and Environmental
Opportunities Management Co., LLC, some of our significant stockholders. In
addition, if we propose to register any shares of common stock under the
Securities Act, either for our own account or for the account of other security
holders, these stockholders are entitled to receive notice of that registration
and may include their shares in that registration. These registration rights are
subject to customary conditions and limitations, including the right of the
underwriters of an offering to limit the number of shares of common stock to be
included in the registration, as well as to limit the number held by security
holders with registration rights to be included in that registration. We are
generally required to pay all registration expenses relating to any
registration.

STOCKHOLDER RIGHTS PLAN

     Our board of directors has adopted a stockholder rights plan. The rights
plan is designed to help insure that all stockholders of Waterlink receive fair
value for their shares of common stock in the event of any proposed takeover of
Waterlink and to guard against the use of partial tender offers or other
coercive tactics to gain control of Waterlink without offering fair value to
Waterlink's stockholders. The rights will cause substantial dilution to any
acquiring person that attempts to acquire Waterlink on terms not approved by the
board of directors. The rights should not interfere with any merger or other
business combination approved by the board of directors since, subject to
limitations, we may redeem the rights prior to the time that any person or group
has become an acquiring person.

     Each outstanding share of common stock, including those offered hereby,
includes one right. The right entitles its holder to purchase from Waterlink one
one-hundredth of a share of the series 1 preferred stock at a purchase price of
$65.00, subject to adjustment. The description and terms of the series 1
preferred stock are in the rights agreement between us and American Stock
Transfer & Trust Company, as rights agent, which is filed as an exhibit to the
registration statement of which this prospectus is a part and is incorporated
herein by reference. The rights are not now exercisable, and may never be
exercisable. The rights will expire on the earlier of (a) May 23, 2007, unless
extended, or (b) their redemption or exchange as described below. Until a right
is exercised, it confers no rights to a stockholder.

     In general, until the rights are exercisable, redeemed or exchanged, each
right will trade together with and cannot be separated from the underlying share
of common stock

                                       55
<PAGE>   59

on which the right was declared. The rights will separate from the common stock
if there is a "distribution date." A distribution date would occur on the
earlier of:

     - the first public announcement that a person or group, including any
       affiliate of such person or group, (such person or group, subject to
       certain exemptions, being an "acquiring person") acquired or has obtained
       the right to acquire, beneficial ownership of 15% or more of the
       outstanding shares of common stock; or

     - 10 days (or such later date specified by the board of directors prior to
       the existence of an acquiring person) after the commencement of or the
       first public announcement of an intent to commence a tender offer or
       exchange offer that would result in a person or group becoming an
       acquiring person.

     If a distribution date occurs, the rights would become exercisable and
separately tradable, and Waterlink would issue certificates for the rights as
soon as possible. Any rights which belong to an acquiring person are null and
void.

     When there is an acquiring person, proper provision will be made so that
each holder of a right, other than such acquiring person, will have the right to
receive upon the exercise thereof, at the then current exercise price of the
right, and in lieu of series 1 preferred stock, that number of shares of common
stock which at that time would have a market value of two times the exercise
price of the right.

     When there is an acquiring person and Waterlink is acquired in a merger or
other business combination transaction or 50% or more of its consolidated assets
or earning power are sold, proper provision will be made so that each holder of
a right will have the right to receive, upon the exercise at the then-current
exercise price of the right, that number of shares of common stock of the
acquiring company which at the time of the transaction will have a market value
of two times the exercise price of the right.

     The amount of series 1 preferred stock that the holder of a right is
entitled to receive upon exercise of the right and the purchase price payable
upon exercise of the right are both subject to adjustment. With certain
exceptions, no adjustment in the exercise price will be required until
cumulative adjustments require an adjustment of at least 1% in such exercise
price.

     Any rights that are at any time beneficially owned by an acquiring person,
or any affiliate or associate of an acquiring person, will be null and void and
nontransferable.

     The board of directors may redeem the rights in whole, but not in part, at
a redemption price of $.01 per right, at any time before a distribution date.
Immediately upon the order of redemption of the rights by our board of
directors, and without any further action or notice, the right to exercise the
rights will terminate and the only right of holders of rights will be to receive
the redemption price. At any time after the time that any person or group
becomes an acquiring person and prior to the acquisition by the acquiring person
or group of 50% or more of the outstanding common stock, our board of directors
may exchange the rights, in whole or in part, at an exchange ratio of one share
of common stock per right.

     Before the distribution date, the rights agreement may be amended by
Waterlink without the approval of any holders of rights. After the distribution
date, the rights agreement may be amended by Waterlink without the approval of
any holders of rights in any manner which does not, in the good faith
determination of the board of directors, adversely affect the holders of the
rights, including amendments which add other events

                                       56
<PAGE>   60

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 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.

1997 WARRANTS

     In March 1997, in connection with the execution of a note purchase
agreement, we entered into a warrant agreement where we agreed to issue warrants
to persons agreeing to purchase the notes. Each warrant entitles the holder to
purchase one share of common stock at an exercise price per share of $4.50. None
of the notes were issued but 125,000 warrants were issued, of which 62,500
warrants were outstanding on July 31, 1999. The current holders are Brantley
Capital Corporation, River Cities Capital Fund Limited Partnership and the
entities of which Environmental Opportunities Management Co., LLC is the general
partner. See "Common Stock Ownership". The warrants expire on March 6, 2002. The
exercise price of the 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. As a result of an exchange of
$1,000,000 of convertible subordinated notes for 410,257 shares of common stock,
Waterlink and the holders of the outstanding warrants agreed that in lieu of any
adjustment of the purchase price, additional warrants to purchase an aggregate
of 65,000 warrants with an exercise price of $3.75 were issued to the holders,
pro rata. All other terms of these warrants were governed by the original
warrant agreement.

BANK WARRANTS

     In February 1997, as additional consideration for Bank of America Illinois
entering into our credit agreement, we entered into a warrant agreement where we
issued 225,000 warrants to the bank. Each warrant entitles the holder to
purchase one share of common stock at an exercise price per share of $4.50. All
of the warrants were outstanding on July 31, 1999. The warrants expire on
February 19, 2002. The exercise price of the warrants is subject to adjustment
upon the occurrence of certain events such as the issuance of securities at
prices less than the market price, or upon stock splits, stock dividends,
reorganizations, mergers or consolidations.

GUARANTOR WARRANTS

     In 1997, Brantley Venture Partners III, L.P., a significant stockholder of
Waterlink, had entered into a guaranty of Waterlink debt, along with other
significant shareholders, and had negotiated documentation satisfactory with our
senior lenders. In June 1999, in connection with the execution of the fifth
amendment of Waterlink's credit agreement, the bank insisted that we obtain
guarantees of the repayment of any additional borrowings. We had a very limited
period of time to negotiate an amendment with our senior lenders to enable us to
borrow under the credit agreement and to avoid being in default. The senior
lenders advised us that a guaranty was required and that a new guaranty from
Brantley would be acceptable. Brantley agreed to assist us in this process of
improving our capital structure and providing a guarantee of $2.3 million of
availability for us from our senior lenders, but insisted that each of our
executive officers execute a guaranty and assist in this process. Theodore F.
Savastano, T. Scott King and Michael J. Vantusko, who are the chairman of the
board, chief executive officer and chief financial officer, respectively, of
Waterlink, agreed to guarantee, in the aggregate, up to an additional $.3
million. Robert P.

                                       57
<PAGE>   61

Pinkas, a director of Waterlink, is managing general partner of Brantley. We
agreed to grant these guarantors warrants to purchase, in the aggregate, up to
283,637 shares of common stock at an exercise price of $0.01 per share. The
warrants are immediately exercisable, expire if unexercised in five years, and
contain substantially the same terms as the 1997 warrants referred to above. The
guarantors, the amount of Waterlink senior indebtedness guaranteed and the
number of shares to be issuable to each upon exercise of warrants granted to
them as follows:

CERTAIN ANTI-TAKEOVER CONSIDERATIONS

     Our certificate of incorporation and amended and restated bylaws, contain
certain provisions which operate only with respect to an extraordinary corporate
transaction involving Waterlink or any of our subsidiaries and which are
designed to encourage any person who desires to take control of and/or acquire
Waterlink to enter into negotiations with the board of directors, thereby making
more difficult the acquisition of Waterlink by means of a tender offer, a proxy
contest or other non-negotiated means. In addition to encouraging any person
intending to attempt a takeover of Waterlink to negotiate with the board of
directors, these provisions also curtail that person's use of a dominant equity
interest to control any negotiations with the board of directors. Under those
circumstances, the board of directors may be better able to make and implement
reasoned business decisions and protect the interests of all of the
stockholders. A copy of our certificate of incorporation and bylaws are filed as
exhibits to the registration statement of which this prospectus is a part.

     CLASSIFIED BOARD OF DIRECTORS.  Our certificate of incorporation provides
for a classified board of directors in which directors are divided into three
classes. Each class is elected for a term of three years expiring at successive
yearly intervals. Additionally, subject to any rights of holders of preferred
stock, only a majority of the board of directors then in office has the
authority to fill any vacancies on the board of directors, including vacancies
created by an increase in the number of directors. Moreover, because our
certificate of incorporation provides for a classified board of directors,
Delaware law provides that the stockholders may remove a member of the board of
directors only for cause. 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.

     AMENDMENT OF THE CERTIFICATE OF INCORPORATION AND BYLAWS.  The certificate
of incorporation 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 our
certificate of incorporation and bylaws, including certain of the provisions
discussed above.

                                       58
<PAGE>   62

     LIMITATIONS ON STOCKHOLDER ACTION BY WRITTEN CONSENT; SPECIAL
MEETINGS.  Stockholder action can be taken only at an annual or special meeting
of stockholders. Our certificate of incorporation prohibits stockholder action
by written consent in lieu of a meeting. Additionally, special meetings of
stockholders can be called only by a majority of the entire board of directors
or by the president or chairman of the board, subject to any rights of holders
of preferred stock. Stockholders are not permitted to call a special meeting or
to require that the board of directors 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 of directors.

     NOMINATIONS OF DIRECTORS AND STOCKHOLDER PROPOSALS.  Our bylaws establish
an advance notice procedure with regard to the nomination other than by, or at
the direction of, the board of directors of candidates for election as directors
and with regard to stockholder proposals to be brought before an annual meeting
of stockholders. The nomination procedure provides that only persons who are
nominated by, or at the direction of, the board of directors, or by a
stockholder who has given timely written notice to the secretary prior to the
meeting at which directors are to be elected, are eligible for election as
directors. 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 of directors or brought before the
meeting by, or at the direction of, the board of directors or by a stockholder
who has given timely written notice to the secretary of that stockholder's
intention to bring that matter before the meeting. The notice from the
stockholder must also meet information requirements, as further set forth in our
bylaws.

     If the officer 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,
that person is not eligible for election as a director, or such business is not
to be conducted at that meeting, as the case may be.

     FAIR PRICE PROVISION.  The certificate of incorporation, in the "fair price
provision," requires the approval by the holders of 80% of the voting power of
the outstanding capital stock of Waterlink entitled to vote on all matters
submitted to the stockholders, generally as a condition for mergers and certain
other business combinations involving Waterlink and any holder of more than 10%
of such voting power, or an "interested stockholder." The fair price provision
does not apply if the transaction is either (a) approved by a majority of the
members of the board of directors who are not affiliated with the interested
stockholder and who were directors before the interested stockholder became an
interested stockholder or (b) certain minimum price and procedural requirements
are met. If the transaction satisfies either of these criteria, the usual
requirement of applicable law, regulations and other provisions of our
certificate of incorporation would apply.

     SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW.  We are a Delaware
corporation subject to section 203 of the Delaware General Corporation Law.
Section 203 provides in general that an interested stockholder acquiring more
than 15% of the outstanding voting stock of a corporation subject to Section 203
but less than 85% of such stock may not engage in certain business combinations
(as defined in Section 203) with

                                       59
<PAGE>   63

the corporation for a period of three years after the date on which the
stockholder became an interested stockholder unless:

     - prior to that date the corporation's board of directors approves either
       the business combination or the transaction in which the stockholder
       became an interested stockholder; or

     - the business combination is approved by the corporation's board of
       directors and authorized by a vote of at least 66 2/3% of the outstanding
       voting stock of the corporation not owned by the interested stockholder.

     A business combination includes mergers, asset sales and other transactions
resulting in financial benefit to a stockholder. Section 203 could prohibit or
delay mergers or other takeover or change of control attempts with respect to
Waterlink and, accordingly, may discourage attempts that might result in a
premium over the market price for the shares held by stockholders.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is American Stock
Transfer & Trust Company.

                         REPORT OF INDEPENDENT AUDITORS

To the Board of Directors and Shareholders of
Waterlink, Inc.

     We have audited the accompanying consolidated balance sheets of Waterlink,
Inc. and subsidiaries as of September 30, 1998 and 1997, and the related
consolidated statements of operations, shareholders' equity and cash flows for
each of the three years in the period ended September 30, 1998. 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, 1998 and 1997, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended September 30, 1998, in conformity with generally
accepted accounting principles.

                        WATERLINK, INC. AND SUBSIDIARIES

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                               SEPTEMBER 30, 1998

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

1.   ACCOUNTING POLICIES

     PRINCIPLES OF CONSOLIDATION -- The consolidated financial statements
include the accounts of Waterlink, Inc. and its wholly-owned subsidiaries (the
"Company"). All significant intercompany accounts and transactions have been
eliminated upon consolidation.

     FISCAL YEAR END -- The Company's fiscal year ends on September 30th.
References in the notes to the financial statements to the years 1998, 1997 and
1996 refer to the fiscal years ended September 30, 1998, 1997 and 1996,
respectively.

     CASH EQUIVALENTS -- The Company considers all highly liquid investments
with a maturity of three months or less when purchased to be cash equivalents.

     CONTRACTS AND 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 are
recognized in the period in which they are determined. Provisions are made
currently for all known or anticipated losses. Variations from estimated
contract performance could result in a material adjustment to operating results
for any fiscal quarter or year. Claims for extra work or changes in scope of
work are included in revenues when collection is probable.

     Contract costs include all direct engineering, material and labor costs, as
well as applicable overheads related to contract performance. General and
administrative expenses are charged to expense as incurred.

     Revenues from the remaining equipment and product sales are recognized when
shipped.

     INVENTORIES -- Inventories are valued at the lower of cost or market. Cost
is determined using the first-in, first-out (FIFO) method.

     CONCENTRATIONS OF CREDIT RISK -- Financial instruments which potentially
subject the Company to concentrations of credit risk consist principally of cash
equivalents, trade receivables and notes receivable. The Company places its cash
equivalents with major 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. Notes receivable of approximately $2,800,000 from one customer are
classified in other long-term assets and are collateralized. Losses from credit
sales are provided for in the financial statements and have historically been
within management's expectations.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- CONTINUED

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

     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 (See Note 7).

     FOREIGN CURRENCY TRANSLATION -- Assets and liabilities of subsidiaries are
translated at the rate of exchange in effect on the balance sheet date; income
and expenses are translated at the average rates of exchange prevailing during
the year. The related translation adjustments are reflected as a separate
component of shareholders' equity. Foreign currency gains and losses resulting
from transactions are included in the results of operations and amounted to a
net gain of $91,000 in 1998 and $167,000 in 1997.

     EARNINGS (LOSS) PER SHARE -- In 1997, the FASB issued SFAS No. 128,
Earnings Per Share, which replaced the previously reported primary and fully
diluted earnings per share with basic and diluted earnings per share. In
addition, the Securities and Exchange Commission issued Staff Accounting
Bulletin (SAB) No. 98, which became effective in February 1998. SAB 98 revises
the views of the staff contained in certain topics of the staff accounting
bulletin series, including SAB No. 83 -- Earnings Per Share Computations in an
Initial Public Offering, to be consistent with the provisions of SFAS No. 128.
All earnings per share amounts conform to the requirements of SFAS No. 128 and
SAB No. 98, where applicable (see Note 12).

     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.

     IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS -- In June 1997, the FASB
issued Statement No. 130, Reporting Comprehensive Income, which establishes
standards for the reporting and display of comprehensive income and its
components. This Statement is intended to address the concerns of financial
statement users' for the increasing number of items that bypass the income
statement, such as foreign currency translation adjustments. The Statement is
effective for the Company in fiscal 1999. The Company does not expect the
adoption of this Statement to have a material effect on the Company's financial
statements.

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

     In June 1997, the FASB issued SFAS No. 131, Disclosures about Segments of
an Enterprise and Related Information, which changes the way public companies
report segment information in annual financial statements. The Statement also
requires public companies to report selected segment information in interim
financial reports to shareholders. The Statement is effective for the Company in
fiscal 1999 and restatement of comparative information for earlier years is
required in the initial year of adoption. The implementation of the 1999
Strategic Operating Plan will require the Company to present segmented industry
information upon adoption of SFAS No. 131.

     In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, which provides a comprehensive and
consistent standard for the recognition and measurement of derivatives and
hedging activities. The Statement will require, among other things, that all
derivatives be recorded on the balance sheet at fair value. The Statement is
effective for the Company in fiscal 2000. The Company has not yet determined
what the effect of adopting SFAS No. 133 will be on its operations or financial
position.

RECLASSIFICATIONS

     Certain amounts reported in the 1997 financial statements have been
reclassified to conform to the 1998 presentation.

2.   ACQUISITIONS

     On March 2, 1998, the Company acquired Chemitreat Services, Inc.
("C'treat") for approximately $4,500,000; consisting of $2,250,000 in cash and
$2,250,000 in convertible subordinated notes. C'treat designs and manufactures
pure watermakers for use in the global offshore energy industry. The purchase
price includes approximately $3,685,000 of goodwill, which is being amortized on
a straight-line basis over 40 years.

     On March 25, 1998, the Company acquired Aquafine Engineering Services
Limited ("AES") and Purac Engineering Incorporated ("Purac") in a single
transaction for approximately $7,572,000 in cash. AES designs and manufactures
industrial and municipal water and wastewater systems and solutions principally
for the United Kingdom market. Purac designs water and wastewater systems
principally for the United States municipal market. The purchase price includes
approximately $3,174,000 of goodwill, which is being amortized on a
straight-line basis over 40 years.

     On June 5, 1998, the Company acquired Barnebey & Sutcliffe Corporation
("Barnebey"), Sutcliffe Speakman Carbons Limited ("Carbons") and Sutcliffe
Croftshaw Limited ("Croftshaw") in a single transaction for approximately
$45,000,000 in cash. Barnebey is located in the United States and Carbons and
Croftshaw are located in the United Kingdom. These three companies ("Carbons
Group") design, manufacture and market products and services utilizing activated
carbon for separation, concentration and purification of water, liquid and
gases. The purchase price includes approximately $29,441,000 of goodwill, which
is being amortized on a straight-line basis over 40 years.

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

     During fiscal 1997, the Company completed five acquisitions of companies
that design and produce water and wastewater treatment systems. The Nordic Water
Products Group ("Nordic Group") was purchased effective March 5, 1997 for
approximately $11,256,000, consisting of $10,721,000 in cash and $535,000 of
seller notes. Bioclear Technology, Inc. ("Bioclear") and Lanco Environmental
Products, Inc. ("Lanco") were purchased effective June 27, 1997. The purchase
price for Bioclear was approximately $20,391,000, which consisted of $14,488,000
in cash, $2,285,000 of assumed debt and 328,947 shares of Common Stock valued at
$11 per share. Lanco was purchased for $2,200,000 in cash. Mellegard V.A.
Maskiner AB ("Meva") was purchased effective September 12, 1997 for
approximately $7,730,000, consisting of $6,059,000 in cash and $1,671,000 of
seller notes. Hycor Corporation ("Hycor") was purchased effective September 30,
1997 for approximately $17,002,000, consisting of $13,500,000 in cash,
$2,250,000 in convertible subordinated notes, $502,000 of assumed debt and
41,095 shares of Common Stock at $18.25 per share. The aggregate purchase price
of the 1997 acquisitions included approximately $46,316,000 of goodwill (Nordic
Group -- $5,919,000; Bioclear -- $17,849,000; Lanco -- $1,833,000;
Meva -- $5,844,000 and Hycor -- $14,871,000), which is being amortized on a
straight-line basis over 40 years. During fiscal 1998, the Company made the
decision to exit the Bioclear business due to the lack of order inflow and
proposal opportunities, the unreliability of Bioclear's niche market, and the
turnover in upper management of Bioclear. As a result of the Company's decision
to exit the business, the unamortized balance of Bioclear goodwill was written
off as part of the special charges to operations discussed in Note 7.

     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 $8,000,000, consisting of $3,500,000 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 $2,700,000, consisting of $1,300,000
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
$5,200,000, consisting of $2,600,000 in cash and 611,784 shares of Common Stock
valued at $4.25 per share. The aggregate purchase price of the 1996 acquisitions
included approximately $9,365,000 of goodwill (Mass Transfer
Systems -- $5,737,000; Aero-Mod -- $78,000 and Water Equipment
Technologies -- $3,550,000), which is being amortized on a straight-line basis
over 40 years.

     All of the acquisitions were accounted for as purchases. The purchase price
allocations for certain of the Company's 1998 acquisitions have been based on
preliminary estimates, which may be revised at a later date, due primarily to
obtaining property appraisals and actuarial valuations. The Company does not
believe that these revisions will result in a significant change to the purchase
allocations. The consolidated statements 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.

     Under the terms of certain of the purchase agreements, the Company may be
required to make additional purchase consideration payments of up to $2,468,000,
contingent upon

the achievement of specified operating results through fiscal 2000. The payments
that are expected to be required for meeting fiscal 1999 and 2000 targets are
$1,468,000 and $1,000,000, respectively. Any such additional purchase
consideration payments will be treated as additional goodwill for accounting
purposes.

     The following unaudited pro forma information presents the consolidated
results of operations of the Company assuming the acquisitions discussed above
were completed on October 1, 1996:

     On February 19, 1997, the Company entered into a credit facility with Bank
of America National Trust & Savings Association ("Pre IPO Credit Facility").
Proceeds from the Pre IPO Credit Facility were used to acquire the Nordic Group
and to refinance

certain indebtedness in connection with the acquisition. As additional
consideration for the Pre IPO Credit Facility, the Company granted the Bank,
pursuant to an agreement dated February 19, 1997, 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 share) was treated as an original issue discount and was subsequently
written off in connection with the extraordinary charge discussed in Note 8. The
warrants under this agreement have not been exercised as of September 30, 1998.

     On June 27, 1997, concurrent with the closing of its Initial Public
Offering, the Company terminated its Pre IPO Credit Facility and entered into
its $40,000,000 three year, secured, domestic revolving credit facility with
Bank of America National Trust & Savings Association as agent (the "Post IPO
Credit Facility"). The Post IPO Credit Facility also permits the Company's
overseas subsidiaries to incur up to $10,000,000 of additional unsecured
indebtedness.

     On June 5, 1998, concurrent with the acquisition of the Carbons Group, the
Company amended and restated its Post IPO Credit Facility by entering into a
$110,000,000 secured, domestic facility, comprised of a $75,000,000 revolving
facility and a $35,000,000 term loan (the "New Domestic Facility"). On September
30, 1998, the New Domestic Facility was amended to allow for the implementation
of the 1999 Strategic Operating Plan described in Note 7 and the Company reduced
the New Domestic Facility to $87,000,000, comprised of a $52,000,000 revolving
facility and a $35,000,000 term loan (the "Amended Credit Facilities"). The
Company's Amended Credit Facilities expire on May 19, 2003, and combined with
the three oversees facilities will be utilized to fund operating activities of
the Company, as well as future acquisitions.

     Availability for future borrowings under the Amended Credit Facilities is
based on a multiple of the Company's pro forma earnings before interest, taxes,
depreciation and amortization. At September 30, 1998, approximately $4,100,000
was available for future borrowings under the Amended Credit Facilities.

     Loans under the Amended Credit Facilities 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
credit facilities bear interest based on a designated London interbank offering
rate ("LIBOR") or prime plus spreads ranging from 100 to 225 basis points,
depending on the Company's aforementioned leverage ratio. Certain borrowings
under the Amended Credit Facilities are subject to an interest rate swap
agreement (see Note 14).

     The Amended Credit Facilities restrict or prohibit the Company from taking
many actions, including paying dividends and incurring or assuming other
indebtedness or liens. The banks that participate in the Amended Credit
Facilities also must approve most acquisitions. The Company's obligations under
the Amended Credit Facility are secured by liens on substantially all of the
Company's domestic assets, including equipment, inventory, accounts receivable
and general intangibles and the pledge of most of the stock of the Company's
subsidiaries. The Company has guaranteed the payment by its three overseas

subsidiaries of their obligations under the overseas facilities. The three
overseas subsidiaries have given a negative pledge of their assets in connection
with their facilities.

     The conversion rate on convertible subordinated notes payable to former
shareholders of acquired companies range from $15.63 to $22.25.

     In March 1997, the Company entered into a note purchase agreement (the
"Note Purchase Agreement") pursuant to which the Company could issue, and
several purchasers had committed to purchase, five year subordinated notes (the
"1997 Notes"). The 1997 Notes were not drawn on by the Company and upon the
consummation of the Initial Public Offering the Note Purchase Agreement
terminated in accordance with its terms. 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 at a purchase price
of $4.50 per share. The aggregate fair value of the 125,000 warrants issued of
$148,000 ($1.18 per share) was initially capitalized as deferred financing costs
and was subsequently written off in connection with the extraordinary item
discussed in Note 8. At September 30, 1998, warrants to purchase 62,500 shares
of Common Stock were outstanding.

6.   LEASES

     The Company leases certain facilities and equipment under operating leases,
some of which are with entities controlled by former shareholders of certain
acquired businesses. Rent expense totaled $2,072,000 in 1998, $959,000 in 1997
and $241,000 in 1996. Related party rent expense included in these totals
amounted to $758,000 in 1998, $438,000 in 1997 and $116,000 in 1996. Aggregate
future minimum lease payments under noncancelable operating leases at September
30, 1998 are as follows:

7.  SPECIAL CHARGES

     During the fourth quarter of fiscal 1998, the Company's Board of Directors
approved the 1999 Strategic Operating Plan (the "1999 Plan") which is designed
to reorganize the Company from a holding company with 23 operating companies
into five integrated divisions that focus on specific market segments. The 1999
Plan, which will eliminate redundant costs and improve operating efficiencies,
is expected to be substantially

completed by the end of fiscal 1999. The plan includes costs associated with the
exiting and consolidation of certain facilities and employee termination costs.
Costs associated with this plan of approximately $2,858,000 were recognized
during 1998. The 1999 Plan will reduce the Company's domestic and foreign
workforce by approximately 75 people and eliminate certain production-related
functions no longer required. At September 30, 1998, 41 employees have been
terminated in conjunction with the 1999 Plan. Due to the timing of certain
termination benefits and facility consolidation costs, the reserve is expected
to be utilized throughout 1999 and 2000. Other costs associated with the 1999
Plan of approximately $1,000,000, which do not meet the criteria for recognition
at September 30, 1998, will be recognized in future periods as incurred. The
following table summarizes the provisions, payments and remaining reserves
associated with the 1999 Plan:

     The Company also recorded a $17,284,000 non-cash charge during the fourth
quarter of 1998, consisting of $15,967,000 related to the impairment of goodwill
associated with the June 1997 Bioclear acquisition and $1,317,000 to write off
the cumulative translation adjustment component of Bioclear's equity. In
conjunction with the 1999 Plan, the Company determined that it would exit the
acquired Bioclear business and the associated goodwill was therefore, not
recoverable. The impairment charge was determined by reducing the carrying value
of Bioclear's assets to fair value utilizing a certified independent third party
valuation.

     The Company also incurred a special charge during the third quarter of
fiscal 1998 of approximately $1,494,000 primarily attributable to contractual
obligations of the Company to its former chief executive officer, who resigned
in June 1998, and costs necessary to recruit executives to the Company.

     The special charges of $2,630,000 for the year ended September 30, 1997
resulted primarily from the issuance, concurrent with the Initial Public
Offering, of a ten year option to purchase 100,000 shares of common stock at a
price of $0.10 per share to an officer of the Company pursuant to terms of an
employment agreement. Of this amount, approximately $1,138,000 was non-cash and
the remainder represented cash obligations related principally to the
reimbursement of income taxes resulting from the stock option issuance.

8.   EXTRAORDINARY ITEM

     The Company used a portion of the proceeds from its Initial Public Offering
to repay substantially all of its outstanding indebtedness. In addition,
concurrent with the Initial Public Offering the Company canceled the Note
Purchase Agreement discussed in Note 5.

In connection with the early retirement of certain indebtedness and the
cancellation of the Note Purchase Agreement, the Company realized an
extraordinary charge of $385,000, net of taxes of $257,000, related to the
write-off of unamortized debt issuance costs and discounts associated with this
indebtedness. This extraordinary item on a per share basis - assuming dilution
was $0.05 for the year ended September 30, 1997.

     In connection with acquisitions made in 1998, the Company recorded deferred
tax asset valuation reserves as part of purchase price allocations totaling
$7,417,000 in the United Kingdom, $1,497,000 in Germany and $509,000 in the
United States due primarily to net operating loss carryforwards existing in
these tax jurisdictions. The benefit of these net operating loss carryforwards
realized in the future will be recorded as a reduction of goodwill rather than
as a credit to income tax expense during that period. During 1998, an income tax
benefit of $350,000 was recorded which resulted in a corresponding decrease in
goodwill.

     For tax purposes, the Company has U.S. federal loss carryforwards of
$17,629,000 which expire in the year 2018 and foreign net operating loss
carryforwards of $25,389,000, $2,211,000 of which expire in 2005 and $23,178,000
that have no expiration date. A valuation allowance has been established for the
entire amount of these net operating loss carryforwards since the realization is
uncertain.

     The Company plans to continue to finance expansion of its operations
outside of the United States by reinvesting undistributed earnings of its
non-U.S. subsidiaries. The amount of undistributed earnings considered to be
indefinitely reinvested for this purpose was approximately $4,600,000 at
September 30, 1998. Accordingly, no provisions have been made for U.S. income
tax purposes on such undistributed earnings. While the amount of any U.S. income
taxes on these undistributed earnings, if distributed in the future, is not
determinable, it is expected that they would be reduced by the utilization of
tax credits or deductions. A distribution of these earnings would be subject to
withholding taxes.

10.   STOCK OPTION PLANS

     During 1998, the shareholders approved the Omnibus Incentive Plan (the
"Omnibus Plan"), which provides for compensatory equity based awards to officers
and certain other key employees of the Company. 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 Company's 1995 Stock Option Plan (the "Stock Option Plan") provides
grants to officers, certain other key employees and directors of awards
consisting of "incentive stock options" as defined under the provisions of
Section 422 of the Internal Revenue Code and non-qualified stock options. All
options granted under the Stock Option Plan expire ten years after the date of
grant (see Note 11).

     The Company's 1997 Non-Employee Director Stock Option Plan (the "Director
Plan") is authorized to issue up to 150,000 shares of Common Stock. Each
non-employee director is automatically granted an option to purchase 3,000
shares of Common Stock. In addition, on each anniversary date of the Director
Plan, each of the Company's then non-employee directors who have served at least
six-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.
Options granted under the Director Plan expire ten years after the date of grant
(see Note 11).

     Collectively, 2,750,000 shares of Common Stock are available for granting
of awards under the above plans at September 30, 1998.

     Under the Company's Employee Stock Purchase Plan (the "Stock Purchase
Plan"), the Company is authorized to issue up to 500,000 shares of Common Stock.
Under the terms of the Stock Purchase Plan, employees can choose to have up to
20% of their annual compensation withheld to purchase Common Stock. The exercise
price for shares subject to purchase under options granted shall be 85% of the
fair market value of the Common Stock on the first day of the purchase period,
unless otherwise determined by the compensation committee. On the last day of
the purchase period of any offering of shares made under the Stock Purchase
Plan, each outstanding option shall automatically be exercised. At any time
prior to the end of the purchase period applicable to each offering, an employee
is permitted 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. The employee has the right to receive in cash the amount
accumulated in such account. The Stock Purchase Plan will terminate in 2007.

11.   STOCK BASED 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 has elected to follow APB Opinion No. 25, "Accounting for Stock
Issued to Employees" ("APB 25"), and related Interpretations and accordingly,
recognizes no compensation

expense for stock options granted at fair value. Management believes that the
alternative fair value accounting provided for under FASB Statement No. 123,
"Accounting For Stock Based Compensation" ("SFAS 123"), requires use of option
valuation methods that were not developed for use in valuing employee stock
options. Under APB 25, compensation expense has been recognized for all options
granted at less than the fair market value of the Company's common shares on the
date of grant (see Note 7).

     Pro forma information regarding net income and earnings per share is
required by SFAS 123 and has been determined as if the Company had accounted for
its employee stock options under the fair value method of that Statement. The
fair value of these options and the options granted as part of the Plan were
estimated at the date of grant using a Black-Scholes option pricing model. The
Company utilized the following weighted-average assumptions for 1998, 1997 and
1996; risk-free interest rate of 6.0%, dividend yield rate of 0% and a
weighted-average expected life of the options of 5 years. Further, the
volatility factor of the expected market price of the Company's stock was 26% in
1998 and 30% in 1997 and 1996. Using the Black-Scholes model, the
weighted-average grant-date fair value of options granted during 1998, 1997 and
1996 in the Stock Option Plan follows:

  Less than exercise price        --       --         --        --      1.54     4.40
</TABLE>

     The weighted-average grant-date fair values of the shares granted during
1998 and 1997 under the Stock Purchase Plan were $2.14 and $4.86, respectively.

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

     For purposes of pro forma disclosures, the estimated value of the options
is amortized to expense over the options' vesting period. The pro forma results
are not necessarily

</TABLE>

     For the fiscal year ended September 30, 1998, certain issuances of
potential common stock were excluded from the computation of diluted earnings
per share since their inclusion in the computation would have an anti-dilutive
effect. Further, certain outstanding convertible subordinated notes in 1997 and
1996 have been excluded from the computation of diluted earnings per share,
since they would have an anti-dilutive effect on earnings per share.

13.   RETIREMENT PLANS

     In conjunction with the acquisition of the Carbons Group on June 5, 1998,
the Company acquired two defined benefit pension plans. The Company acquired a
U.K. plan, which covers substantially all of the employees of Carbons and
Croftshaw, and a U.S.

</TABLE>

     In addition to the defined benefit plans acquired in the Carbons Group
acquisition, the Company has certain other employees, all located in the United
Kingdom, which currently participate in a defined benefit pension plan operated
and funded by their former parent company. In accordance with the terms of the
sale and purchase agreement, the Company is required to make contributions to
the plan for a period not to exceed twelve months from the acquisition date, or
March 1999. Upon expiration of the twelve-month period, the participants (and
related plan assets and benefit obligation) will be transferred into a defined
benefit pension plan funded and administered by the Company's U.K. operations.
The net asset or obligation associated with this plan is not determinable at
September 30, 1998.

     The Company also sponsors a defined contribution plan which covers
substantially all domestic employees. Company contributions to the Plan totaled
$94,000 in 1998 and $13,000 in 1997. No Company contributions were made in 1996.

14.   FINANCIAL INSTRUMENTS

     The carrying values 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. Substantially all of the Company's
long-term debt obligations, except for the convertible subordinated
notes -- related parties, have variable rates and cost approximates fair value
at September 30, 1998. The convertible subordinated notes -- related parties do
not have a ready market and cost is assumed to approximate fair value. The
aggregate carrying value of these notes is $5,921,000 at September 30, 1998,
with interest rates ranging from 3.00% to 5.81% and maturity dates ranging from
September 1999 to March 2001.

     During 1998, the Company entered into an interest rate swap agreement with
a major commercial bank to modify the interest characteristics of its Amended
Domestic Facility. The agreement involves the exchange of amounts based on a
fixed rate of interest for an amount based on a LIBOR-based floating rate over
the life of the agreement without an exchange of the notional amount upon which
the payments are based. The agreement, which expires on December 30, 1999, fixes
the Company's LIBOR-based rate at 5.25% on a notional amount of $75,000,000. The
differential to be paid or received as the interest rates change is accrued and
recognized as an adjustment of interest expense related to the debt. The amount
payable to or receivable from its counterparty is included in other

liabilities or assets. The fair value of the swap agreement and changes in the
fair value as a result of changes in market interest rates are not recognized in
the financial statements. The fair value of the swap agreement at September 30,
1998 was a loss of $388,000. The counterparty to the agreement is a major
commercial bank. Management believes that any loss related to credit risk is
remote.

     The Company uses a limited number of foreign exchange instruments,
primarily forward contracts, to manage exposure to currency rate fluctuations
primarily related to the purchases of inventory. Gains and losses incurred on
foreign exchange instruments identified as hedges are deferred and recognized in
income in the same period as the hedged transaction. The deferred gains or
losses from hedging anticipated transactions were not material to the Company's
financial condition at September 30, 1998 and 1997.

15.   GEOGRAPHIC AREA DATA

     The Company operates in a single industry, providing integrated water and
wastewater treatment solutions to industry and municipalities worldwide. The
Company has a strategy of acquisition and internal growth to provide integrated
products, technologies and services to water users globally. Export sales
represented approximately one-fifth of U.S. sales in 1998 and one-third in 1997
and 1996.

     Revenue transfers between geographic areas and other intergeographic
eliminations are not material. The Company does not derive more than 10% of its
total revenue from any individual customer.

existing holders of convertible subordinated notes to reduce the note principal
amount from $2,000,000 to $1,000,000 in exchange for 410,257 shares of Common
Stock. In addition, the maturity date of the $1,000,000 principal amount of the
convertible subordinated note was extended from September 30, 1999 to October 1,
2000; the interest rate on the remaining note balance was increased from 5.81%
to 6.06%; and the conversion rate was decreased from $22.25 per share to $6.75

5. SPECIAL CHARGES

     During the fourth quarter of fiscal 1998, the Company's Board of Directors
approved the 1999 Strategic Operating Plan (the "1999 Plan"), which is designed
to restructure the Company from a holding company with 23 operating companies
into five integrated divisions that focus on specific market segments. The 1999
Plan, has eliminated redundant costs and is intended to improve operating
efficiencies, is expected to be substantially completed by the end of fiscal
1999. The plan includes costs associated with the exiting and consolidation of
certain facilities and employee termination costs. In conjunction with the 1999
Plan, the Company expected to reduce its domestic and foreign workforce by
approximately 75 people and eliminate certain administrative and
production-related functions no longer required. Through June 30, 1999, 114
employees have been terminated in conjunction with the 1999 Plan. Of the 114
employees terminated, 90 people have received, or are currently receiving,
termination benefits in accordance with Company guidelines or local laws.
Further, six facilities have been closed or relocated as of June 30, 1999, with
one additional facility scheduled to relocate prior to September 30, 1999. Other
costs associated with the 1999 Plan of approximately $1,700,000, which did not
meet the criteria for recognition at September 30, 1998, are expected to be
incurred during fiscal 1999, of which, the Company incurred $784,000 and
$1,487,000 during the quarter and nine months ended June 30, 1999, respectively.

     The following table summarizes the provisions, payments and the unpaid
balances associated with the 1999 Plan. The unpaid balances, or reserve, are
expected to be utilized through fiscal 1999 and 2000:

</TABLE>

     In conjunction with its 1999 Plan, the Company determined that it would
exit the acquired Bioclear business. During the fourth quarter of fiscal 1998,
the assets of Bioclear, primarily related to its manufacturing facility located
in Winnipeg, Canada, were reduced to their estimated net realizable value. Based
on the status of the sales process and Waterlink's June 1999 decision regarding
how to best dispose of the facility, the Company further reduced the estimated
net realizable value of these remaining assets by $1,300,000 and recorded this
change in accounting estimate during the quarter ended June 30, 1999.

     As a result of the reduction in estimated net realizable value of the
remaining Bioclear assets, together with the termination and facility
consolidation costs previously discussed, the Company has recorded special
charges totaling $2,084,000 and $2,787,000 during the quarter and nine months
ended June 30, 1999, respectively.

     The Company incurred special charges of $1,494,000 during the three and
nine months ended June 30, 1998 primarily attributable to contractual
obligations to its former chief executive officer, who resigned in June 1998,
and costs necessary to recruit executives to Waterlink.

</TABLE>

     For all periods presented, certain issuances of potential common stock and
certain outstanding convertible subordinated notes were excluded from the
computation of earnings per share, assuming dilution, since their inclusion in
the computation would have an anti-dilutive effect.

7. SUBSEQUENT EVENTS

     On July 9, 1999, Waterlink entered into an amendment of its $87 million
domestic credit facility. This amendment was effective on June 29, 1999 and
waives until October 8, 1999 certain financial covenants that were not otherwise
satisfied at June 30, 1999, assuming Waterlink realizes not less than $700,000
of operating income on a monthly basis for the remainder of fiscal 1999. As part
of this amendment, $2.6 million of borrowings were made available to Waterlink
as the result of third party guarantees.

     In connection with assisting in the process of improving our capital
structure by providing the $2.6 million of guarantees, Waterlink granted the
guarantors warrants to purchase, in the aggregate, up to 283,637 shares of
Waterlink common stock at an exercise price of $.01 per share. The warrants are
immediately exercisable and expire if unexercised

in five years. Of the 283,637 warrants, 125,000 were issued at the time the
guarantees were issued and the remaining 158,637 warrants will be issued upon
shareholder approval. The 125,000 warrants were valued at $2.74 per warrant and
the remaining 158,637 will not be valued until shareholder approval is obtained.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law (the "DGCL") permits
the indemnification of the directors and officers of Waterlink. Our Bylaws
provide that it will indemnify the officers, directors, employees and agents of
Waterlink to the extent permitted by the DGCL.

     The certificate of incorporation provides for the indemnification of
directors and officers of Waterlink, and persons who serve or served at the
request of Waterlink 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, Waterlink
shall indemnify any such person seeking indemnification in connection with a
proceeding initiated by such person only if such proceeding was authorized by
Waterlink's board. In the event a claim for indemnification by any person has
not been paid in full by Waterlink after written request has been received by
Waterlink, the claimant may at any time thereafter bring suit against Waterlink
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 certificate of
incorporation is a contract right and shall include the right to be paid by
Waterlink the expenses incurred in defending any such proceeding in advance of
its final disposition. Waterlink maintains insurance, at its expense, to protect
itself and any director, officer, employee or agent of Waterlink against any
such expense, liability or loss, whether or not Waterlink would have the power
to indemnify such person against such expense, liability or loss under state
law.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.

     During the past three years Waterlink issued and sold shares of its capital
stock without registration under the Securities Act of 1933, as amended, in
reliance on the exemption provided therefrom by Section 4(2) of the Secondary
Act, in the transactions described below. In each transaction, Waterlink did not
engage any underwriter, broker or placement agent. In connection with each such
transaction, Waterlink obtained appropriate investment representations
supporting its reliance on such exemption from registration. In such
transactions (other than in connection with the Water Equipment Technologies,
Inc. acquisition), Waterlink obtained representations from the investors that
each was an "accredited investor," as defined in Regulation D under the Act. In
such transactions, appropriate disclosure was provided to each investor to
support Waterlink's reliance on the exemption from registration provided by
Section 4(2) of the Act.

     On September 30, 1996, Waterlink issued 499,996 shares of common stock in
connection with its acquisition of all of the issued and outstanding capital
stock of Water Equipment Technologies, Inc. The shares of common stock were
issued to 11 shareholders of Water Equipment upon the merger of Water Equipment
with and into a wholly-owned subsidiary of Waterlink. The total dollar value of
the 499,996 shares of common stock issued to the shareholders of Water Equipment
in the merger was $2,124,983. On February 28, 1997, the Company issued 111,788
additional shares of common stock to the shareholders of Water Equipment in
payment of an adjustment to the purchase price paid by Waterlink for the issued
and outstanding shares of Water Equipment. The total dollar value of the 111,788
shares of common stock issued to the shareholders of Water Equipment as purchase
price adjustment was $475,099 (or $4.25 per share).

     On October 15, 1996, Waterlink issued 100,000 shares of common stock to

ITEM 17.  UNDERTAKINGS

(a) Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
by a director, officer or controlling person of the registrant in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

                           quarter, provided, however, that such restructuring

                                    AGREEMENT
                                    ---------


         THIS AGREEMENT dated as of April 15, 1999, among WATERLINK, INC., a
Delaware corporation ("Waterlink") and each of the holders (collectively, the
"Holders") of warrants issued pursuant to that certain Warrant Agreement (the
"Warrant Agreement") dated as of March 6, 1997.

                                    RECITALS:

         The Holders hold, in the aggregate, Warrants (the "Outstanding
Warrants") to purchase 62,500 shares of Common Stock. Pursuant to the Warrant
Agreement, upon certain events, adjustments to the number of shares of Warrant
Stock and the Warrant Price are to be made. In connection with a restructuring
of debt and equity held by a certain employee of Waterlink pursuant to an
acquisition, the parties hereto began discussions concerning the appropriate
adjustment to the outstanding warrants under the Warrant Agreement as a result
of said restructuring.

         On April 15, 1999, the parties hereto agreed to the appropriate
adjustment, which agreement is documented hereby. Capitalized terms not
otherwise defined herein shall have the meanings ascribed to them in the Warrant
Agreement.

         NOW THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, and the mutual promises contained
herein, the parties agree as follows:

         1.  In lieu of any change to the Warrant Price of the Outstanding
Warrants and in lieu of any issuance of additional Warrants at the unadjusted
Warrant Price, the parties hereto agree that Waterlink shall issue to the
Holders such number of Warrants as indicated below (the "New Warrants"), which
New Warrants will have a Warrant Price equal to $3.75 (the closing price of a
share of the Common Stock on April 15, 1999):

         2.  The Holders acknowledge and agree that the issuance of the New
Warrants referred to in paragraph 1 above is in full satisfaction of all
obligations of Waterlink to make any adjustment to the Outstanding Warrants or
the Warrant Price pursuant to the Warrant Agreement through the date hereof with
respect to the transactions referred to in the above recitals. The parties
hereto acknowledge and agree that the Warrant Price of the Outstanding Warrants
remains $4.50. The parties hereto further agree that from and after the date
hereof, any calculation pursuant to Section 10 of the Warrant Agreement shall
assume (i) that the number of Warrants outstanding shall be such of the
Outstanding Warrants then outstanding and (ii) the Warrant Price shall be
$2.4375. If any adjustment to the number of Warrants or the Warrant Price shall
hereafter be required pursuant to the Warrant Agreement, Waterlink shall make
the appropriate adjustment to the Warrants then outstanding or their respective
Warrant Price based upon the provisions of Section 10 of the Warrant Agreement,
as modified by this Agreement.

         3.  Each of the Holders represents and warrants that it has not made
any assignment or other transfer of the Warrants or any right or interest
therein.

         4.  This Agreement may be executed in multiple, identical counterparts,
all of which when taken together shall constitute a single document.

         IN WITNESS WHEREOF, the parties have duly executed this Agreement as
of the date first above written. Waterlink, Inc.
