                         INDEPENDENT AUDITORS' REPORT

To the members of Protean plc:

We have audited the accompanying consolidated balance sheet of Protean plc as of
31 March 1997 and the related consolidated profit and loss account, cash flow
statement, reconciliation of net cash flow to movement in net debt, statement
of total recognised gains and losses, reconciliation of movements in
shareholders' funds, and note of consolidated historical cost profits and losses
for the year ended 31 March 1997. These consolidated financial statements are
the responsibility of the management of Protean plc. Our responsibility is to
express an opinion on these consolidated financial statements based on our
audit.

We conducted our audit in accordance with generally accepted auditing standards
in the United Kingdom which do not differ in any material respects from auditing
standards generally accepted in the United States. Those standards require that
we plan and perform our 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
audit provides a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Protean plc and its
subsidiaries as of 31 March 1997 and the results of their operations and their
cash flows for the year ended 31 March 1997 in conformity with generally
accepted accounting principles in the United Kingdom.

Generally accepted accounting principles in the United Kingdom vary in certain
significant respects from generally accepted accounting principles in the United
States. Application of generally accepted accounting principles in the United
States would have affected results of operations for year ended 31 March 1997
and shareholders' funds as of 31 March 1997 to the extent summarised in note 28
to the consolidated financial statements.

                Notes to the Consolidated Financial Statements


(1) Accounting Policies

The principal accounting policies that have been adopted in the preparation of
these financial statements are given below:

Basis of preparation
The consolidated financial statements have been prepared in conformity with
accounting standards applicable in the United Kingdom, under the historical cost
accounting standards. 

Accounting principles generally accepted in the United Kingdom vary in certain
respects from accounting principles generally accepted in the United States.
Application of accounting principles generally accepted in the United States
would have affected the results of operations for periods reported in the year
ended 31 March 1997 and the shareholders' funds at 31 March 1997 to the extent
summarised in note 28 to the consolidated financial statements.

Goodwill
Fair values are ascribed to assets and liabilities of subsidiary companies at
the dates of acquisition. Goodwill, which is the difference between the fair
value of the consideration and the fair value of the assets acquired is dealt
with through reserves in the year of acquisition.

On the subsequent disposal of a previously acquired business, the profit or loss
on disposal is calculated after charging any related goodwill previously taken
to reserves.

Turnover
Turnover comprises amounts charged by Group companies for goods and services
provided to customers and the for value carried out during the year, excluding
sales taxes and inter-company sales.

Depreciation
Depreciation is provided on a straight-line basis on all tangible fixed assets,
with the exception of land, at rates calculated to write off the cost or
valuation of each asset less estimated residual value over its expected useful
life. Leased assets are depreciated over the shorter of their useful life and
the term of the lease. The principal rates used are:

<CAPTION> 
<S>                                                     <C> 
Freehold and long leasehold buildings                     2-4%
Fixtures, fittings and equipment                        10-20%
Plant and machinery                                     10-20%
Computer equipment                                      20-33%
Motor vehicles                                             25%
</TABLE> 

Leases
Tangible fixed assets include assets operated by the Group under finance leases
and hire purchase contracts where the Group has substantially all the risks and
rewards of ownership of the asset. Correspondingly, creditors shown in the
balance sheet include the commitment for the capital element of future lease or
hire purchase payments. The finance element of lease or hire purchase payments
is charged to the profit and loss account over the term of the lease or the hire
purchase contract.

All other leases are treated as operating assets and payments are charged to the
profit and loss account as they are incurred.

         Notes to the Consolidated Financial Statements - (Continued)


(1) Accounting Policies - (Continued)

Stocks
Stocks have been valued at the lower of cost and net realisable value. Cost
includes the cost of materials, labour and an appropriate proportion of
production overhead expenses.

Research and development
Research and development expenditure is written off against the profit and loss
account in the year in which it is incurred.

Taxation
The charge for taxation is based on the profits for the year and takes into
account taxation deferred because of timing differences between the treatment of
certain items for taxation and accounting purposes.

Provision is made for deferred taxation only to the extent that the Directors
consider that a liability will become payable in the foreseeable future. No
provision is made for any additional taxation that might arise should the
retained reserves of certain overseas companies be remitted to the United
Kingdom.

Deferred income
Amounts received from customers for vouchers entitling them to future services
are not credited to revenue until redemption or expiry of the vouchers. The
amount so deferred is calculated by reference to the issue price of the voucher.

Translation of foreign currencies
Assets and liabilities in foreign currencies are expressed in sterling at the
rates of exchange ruling at the end of the financial period. Gains or losses
arising on the translation of net assets of overseas companies, net of related
foreign currency borrowings are taken to reserves. Trading results of overseas
companies are translated into sterling at the average rates of exchange for the
period.

Transactions in foreign currencies are recorded at the rate of exchange at the
date of the transaction or, if hedged forward, at the rate of exchange under the
related forward currency contract. Differences arising between the transaction
date and the payment date are taken immediately to the profit and loss account.

Pension costs
The Group operates a number of pension schemes, covering the majority of
employees, under which contributions by eligible employees and the employing
companies are administered in funds independent from the companies' assets. The
regular cost of providing benefits is charged to profit so as to spread the cost
over the employee working lives on a systematic basis. Variations from regular
cost are spread over the remaining service lives of the employees.

     The adjustment to goodwill in respect of DWA is a cash rebate of tax
     suffered by former subsidiaries of DWA. This has been accounted for as a
     reduction in the fair value of the consideration for the acquisition.

     The adjustment in respect of HPLC Technology Company Arises from a final
     appraisal of the value of net assets acquired, and consists mainly of a
     reduction in the value of stocks.

     The profit before tax (after interest charges of (pound)653,000) included
     in these accounts for FTS Systems Inc is (pound)383,000. The profit after
     tax for the year ended 31 December 1995, the last financial year for which
     the published figures for FTS are available was (pound)1,365,000 and for
     the period from 1 January 1996 to 31 August 1996 (the date of acquisition
     by the Group) was (pound)1,014,000. Prior to the acquisition, the tax
     status of the company was such that the majority of federal and state taxes
     was met by the shareholders.

     FTS Systems Inc, which was acquired during the year, contributed
     (pound)830,000 to the Group's net operating cash flow, paid (pound)541,000
     in respect of repayment of loan finance, paid (pound)105,000 in respect of
     taxation and utilised (pound)76,000 for capital expenditure.

  (25) Pension commitments

      There are three defined benefit and six defined contribution schemes
      within the Group. All schemes have assets held in separate funds
      administered by trustees.

      All defined benefit schemes are subject to valuation by qualified
      actuaries and all valuations assume that investment returns exceed salary
      growth by 2 to 2.50%. The latest valuations were at dates between
      1 February 1994 and 6 April 1995 and in each case the assets exceeded the
      liabilities for benefits that had accrued to members at those dates, when
      using the Project Unit method.

      The largest scheme in the Group is the Elga Pension Scheme, which is a
      defined benefit scheme. The most recent valuation of the scheme was based
      on membership details as at 6 April 1995 using the Defined Accrued Benefit
      method. The market value of scheme assets was (pounds)5,056,064 which,
      together with assets in the form of annuity contracts, represented 99% of
      accrued liabilities allowing for future earnings increases. This valuation
      assumed that the investment returns would be 9% pa and would exceed salary
      growth by 2.50%. (The funding level on the Project Unit method was 106%).

      Details of the other individual operating company schemes are given in the
      financial statements of those companies as appropriate.

      Contributions by Group companies totalled (pounds)875,000 for the year
      which were charged against profit. The pension costs on a basis consistent
      with the requirements of SSAP24, were not materially different from the
      contributions paid.


  (26) Related party transactions

      The Group had no related party transactions which might reasonably be
      expected to influence decisions made by the users of these financial
      statements.

(27)  Post balance sheet Event

Following discussions between Protean plc (Protean) and Culligan Water
Technologies, Inc. (Culligan), a U.S. based manufacturer of water purifying
systems, Protean received a proposal from Culligan to purchase their business,
offering to acquire all of the issued share capital of Protean for 105 million
British pound sterling.  This offer was recommended to shareholders by the Board
of the Company on 24 October 1997 .  The offer was declared wholly unconditional
on 2 December 1997.


(28)  Significant differences between UK and US Accounting Principles

The above accounts have been prepared in accordance with generally accepted
accounting principles (GAAP) in the U.K. which differ in certain material
respects from U.S. GAAP.  The significant differences relate principally to the
following items and the adjustments necessary to restate net income and
shareholders' equity in accordance with U.S. GAAP are shown below.


a) Goodwill

In the consolidated financial statements, goodwill, together with the fair value
of purchased trademarks, patents and other related intangibles, arising on the
acquisition of a subsidiary, is immediately eliminated against reserves.  Under
U.S. GAAP, such goodwill and other intangibles would be capitalised and
amortised against income over the estimated useful lives of the assets, not
exceeding 40 years.  For the purposes of calculating the effect of capitalising
the goodwill on the balance sheet and amortising the goodwill and other
intangibles through the statement of income, a life of 40 years has generally
been assumed.


b) Tangible Asset Revaluation

U.K. GAAP allows the periodic revaluation of land and buildings.  Professional
revaluations of Protean properties were carried out during the past several
years.  Under U.S. GAAP, revaluations would not be permitted and all fixed
assets, other than land, would be depreciated over their estimated economic
lives.  The reconciling adjustments in respect of tangible fixed assets relate
primarily to Elga properties.


c) Ordinary Dividends

Under U.K. GAAP, the proposed dividends on ordinary shares, as recommended by
the directors, are deducted from shareholders' equity and shown as a liability
in the balance sheet at the end of the period to which they relate.  Under U.S.
GAAP, such dividends are only deducted from shareholders' equity at the date of
the declaration of the dividend.


d) Pension Costs (Credits)

The company provides for the cost of retirement benefits based upon consistent
percentages of employees' pension payable as recommended by independent
qualified actuaries.  U.S. GAAP requires that projected benefit obligation
(pension liability) be matched against the fair value of the plans' assets and
be adjusted to reflect unrecognised obligations or assets in determining the
pension cost or credit for the year.

Cash Flows

The above combined financial statements comply with Financial Reporting Standard
No. 1 -- "Cash flow statements" (FRS 1). Its objective and principles are
similar to those set out in Statement of Financial Accounting Standards No. 95
- --"Statement of Cash Flows" (SFAS 95). The principle difference between the
standards relates to classification. Under FRS 1, cash flows are presented for
a) operating activities; b) returns on investments and servicing of finance; c)
taxation; d) investing activities; and e) financing activities. SFAS 95 requires
only three categories of cash flow activities: a) operating; b) investing; c)
financing.

Cash flows arising from taxation and returns on investments and servicing of
finance under FRS 1 would, with the exception of dividends paid, be included as
operating activities under SFAS 95; dividend payments would be included as a
financing activity under SFAS 95. In addition, under FRS 1, cash and cash
equivalents include short term borrowings with original maturities of less than
90 days. SFAS 95 requires that movements on such short term borrowings to be
included in financing activities.


A summarised consolidated cash flow under U.S. GAAP is as follows:

               CULLIGAN UNAUDITED PROFORMA FINANCIAL INFORMATION


     On December 2, 1997, Culligan Water Technologies, Inc. ("Culligan" or the
"Company") declared its cash offer of approximately $174 million to acquire all
of the outstanding shares of Protean plc ("Protean"), a United Kingdom
corporation, unconditional in all respects. As a result, the Company has
successfully completed its offer to acquire Protean. As of December 2, 1997, the
Company owned or received valid acceptances for an aggregate of 97.9% of
Protean's outstanding shares. Subsequent thereto, Culligan acquired the
remaining outstanding shares of Protean in accordance with United Kingdom law
and Protean has become a wholly-owned subsidiary.

     In January 1998, the Company's Board of Directors decided to divest the
Analytical and Thermal Equipment Division of Protean. This Division consists of
8 operating units involved in the manufacture and sale of analytical and thermal
equipment and consumables principally for use in medical, academic, research and
industrial laboratories worldwide. These operations are reflected as
discontinued operations for all periods presented in the accompanying unaudited
condensed pro forma combined financial statements.

     Also reflected in the unaudited condensed pro forma combined financial
information is the $155 million acquisition of the water filtration business of
Ametek, Inc. (Ametek). A wholly owned subsidiary of the Company was merged into
Ametek on August 1, 1997, immediately following the spin-off of Ametek's non-
water filtration operations. As a result of the acquisition, each share of
Ametek common stock was converted into the right to receive .105 shares of
common stock of the Company (or an aggregate of 3,473,298 shares of the
Company's common stock) and cash in lieu of fractional shares.

     The following unaudited condensed pro forma combined financial information
presents the Pro Forma Combined Balance Sheet at October 31, 1997, combining the
historical consolidated balance sheet of the Company and the balance sheet of
Protean as if the transaction had been consummated on October 31, 1997. The
unaudited Pro Forma Combined Statements of Operations for the fiscal year ended
January 31, 1997 and the nine months ended October 31, 1997 give effect to the
acquisitions of Protean and Ametek as if the acquisitions had been consummated
as of the beginning of their respective prior fiscal year. The unaudited Pro
Forma Combined Statement of Operations for the fiscal year ended January 31,
1997 combines the results of the Company for such year with the results of
Protean for the year ended March 31, 1997 and the results of Ametek for the year
ended December 31, 1996. The unaudited Pro Forma Combined Statement of
Operations for the nine months ended October 31, 1997 combines the results of
the Company and Ametek for such nine month period with the results of Protean
for the nine months ended September 30, 1997. Therefore, the results of
operations of Protean for the three months ended March 31, 1997 are included in
both the Pro Forma Combined Statement of Operations for the fiscal year ended
January 31, 1997 and the nine months ended October 31, 1997.

                                     F-23
<PAGE>

     Ametek was acquired by the Company on August 1, 1997. Therefore, the
Company's historical results of operations for the nine months ended October 31,
1997 already include Ametek's results of operations for the three months ended
October 31, 1997. To arrive at Ametek's results of operations for the nine
months ended October 31, 1997, the results of operations for the six months
ended July 31, 1997 must be added to the Pro Forma Combined Statement of
Operations. The results of operations of Ametek for the month of January 1997
are not included in either the Combined Statement of Operations for the fiscal
year ended January 31, 1997 or the nine months ended October 31, 1997.

     The unaudited pro forma financial information of Culligan is presented for
illustrative purposes only and is not necessarily indicative of the combined
results of operations or financial position of Culligan as if the acquisitions
had occurred on the assumed dates, nor is it necessarily indicative of the
future results of operations or financial position of Culligan. The unaudited
pro forma financial information should be read in conjunction with the Company's
Annual Report on Form 10-K for the year ended January 31, 1997 filed with the 
Securities and Exchange Commission.

     The pro forma adjustments applied in the unaudited pro forma financial
information reflect the acquisitions as purchase transactions. Under the
purchase method of accounting, the purchase cost will be allocated to acquired
assets and liabilities based on their relative fair value as of the closing
dates with the excess of the purchase cost over fair value allocated to
goodwill. Such allocations are based on valuations and other studies that are
not yet complete. Accordingly, the final allocations will be different from
those reflected. However, based on current information, the Company does not
presently expect the final allocations to differ materially from the amounts
presented.

         Notes to Unaudited Condensed Pro Forma Combined Balance Sheet
                            (US Dollars in Thousands)

(a) The unaudited Protean balance sheet at September 30, 1997, has been derived
    from the historical financial accounts of Protean and is presented in
    accordance with U.K. generally accepted accounting principles (GAAP). The
    unaudited Protean Balance Sheet has been translated into U.S. dollars using
    an exchange rate of $1.61 per British pound sterling. The pro forma
    adjustments column contains adjustments to present the Pro Forma Combined
    Balance Sheet on a U.S. GAAP basis and to record the effect of purchase
    accounting related to the acquisition of Protean. Certain reclassifications
    have been made to the historical financial statements of Protean to conform
    with the Company's presentation.

(b) To eliminate restricted cash that was held in escrow until the Company's 
    offer was declared unconditional. The restricted cash was used to acquire 
    Protean's outstanding shares.  

(c) To reclassify non-current deferred tax assets from prepaid and other current
    assets.

(d) To record the net assets of discontinued operations (i.e., the Analytical
    and Thermal division) at the estimated proceeds from the sale of such
    operations, plus estimated cash flows during the holding period, less
    estimated interest on debt associated with the discontinued operations.

(e) To reverse the periodic revaluation of certain property, plant and equipment
    allowed for U.K. GAAP purposes. Under U.S. GAAP such revaluations are not
    permitted and all property, plant and equipment, other than land, is
    depreciated over their estimated economic lives. The reduction of property,
    plant and equipment of $332 relates to Protean's continuing operations.

(f) To adjust property, plant and equipment for the estimated step-up to fair
    value in the amount of $840. Under purchase accounting, the purchase cost
    allocated to acquired assets is to be based on the fair value at the
    acquisition date as determined by valuations and other studies which are not
    yet complete. Accordingly, the final allocation may be different from the
    amount reflected in the pro forma, however, based on current information,
    management does not expect the amount to differ materially from the amount
    presented.

(g) To record goodwill related to the acquisition of Protean. Goodwill
    represents the excess of the purchase price paid by the Company over the sum
    of identifiable assets acquired less liabilities assumed. Goodwill will be
    amortized over 40 years.

(h) To record a non-current asset of $1,757 to reflect Protean's pension
    accounting on a U.S. GAAP basis. Protean provides for the cost of retirement
    benefits based upon consistent percentages of employees' pension payables as
    recommended by independent qualified actuaries. U.S. GAAP requires that the
    projected benefit obligation be reduced to the extent of the plans' fair
    value of assets and be adjusted to reflect unrecognized obligations or
    assets in determining the pension cost or credit for the year.

(i) To eliminate Culligan's equity investment in Protean of $30,193 that was 
    recorded on the Company's consolidated balance sheet at October 31, 1997.

                                     F-26

(j) To record direct costs of the acquisition including fees for accounting,
    legal and other financial advisors. The accrued liability also includes
    estimated costs for severance.

(k) To eliminate the equity of Protean.

Operations

a.  The Water Filtration Business statement of operations includes revenues and
    expenses derived from AMETEK's historical cost financial accounts. The
    associated revenues and expenses are either directly attributable to the
    Water Filtration Business or have been allocated to the Water Filtration
    Business based upon methods considered reasonable by management. The
    statements of operations of the Water Filtration Business were prepared in
    contemplation of the acquisition.

b.  The pro forma adjustments do not reflect any operating efficiencies or cost
    savings that may result from the acquired businesses. Also, a final
    determination of the required purchase accounting adjustments has not been
    made, and the earnings results will vary from those pro forma earnings shown
    based on the final adjustments.

c.  To eliminate November and December 1995 sales of $827 and cost of goods sold
    of $359 and selling, general and administrative expenses of $367 related to
    APIC International S.A., a wholly owned subsidiary of the Water Filtration
    Business, that were included in the Water Filtration Business results for
    the year ended December 31, 1996.

d.  To reclassify research and development expenses of $618 included in the
    costs of goods sold of the Water Filtration Business to selling, general and
    administrative expenses for the year ended December 31, 1996. These expenses
    are reclassed to selling, general and administrative expenses in order to
    present the statement of operations of the Water Filtration Business on a
    basis consistent with Culligan.

e.  To reclassify depreciation expense of the Water Filtration Business to cost
    of goods sold by $1,856; and selling, general and administrative expenses by
    $63 for the year ended December 31, 1996, in order to present the statement
    of operations of the Water Filtration Business on a basis consistent with
    Culligan.

f.  To capitalize tooling costs expenses by the Water Filtration Business, net
    of additional depreciation expense related to such capitalized amounts. The
    adjustment results in a net decrease of $45 to cost of goods sold of the
    Water Filtration Business for the year ended December 31, 1996. The
    adjustment is necessary to present the statement of operations of the Water
    Filtration Business in accordance with the accounting policies that will be
    used after the Acquisition.

g.  To record amortization expense of $2,966 and $1,486 for the year ended
    January 31, 1997 and the six months ended July 31, 1997, respectively, for
    goodwill resulting from the excess of the purchase price paid by Culligan
    over the sum of identifiable assets acquired and liabilities assumed. The
    amortization period for goodwill is 40 years. Amortization expense also
    included $160 and $80 for the year ended January 31, 1997 and the six months
    ended July 31, 1997, respectively, for identifiable trademarks which are
    being amortized over 20 years.


                                     F-30

h.  To record interest expense of $1,609 and $813, reflecting one year's and six
    months', respectively, estimated interest expense for the debt of $25,000
    assumed in the Acquisition.

    The effect of a 1/8 percent change in the interest rate on the $25,000 debt
    assumed in the Acquisition would be approximately $31 for the year ended
    January 31, 1997 and $16 for the six months ended July 31, 1997.

i.  To record the tax effect (at 40%) of all pro forma adjustments except
    goodwill and in-process research and development, which is not tax
    deductible.

j.  To adjust the shares of common stock outstanding to reflect the issuance of
    3,466,667 shares of Culligan common stock as if the shares were issued on
    February 1, 1996.

(k)  The Protean statements of operations have been derived from the historical
     financial accounts of Protean and are presented in accordance with U.K.
     generally accepted accounting principles (GAAP). The Protean statements of
     operations for the year ended March 31, 1997 and the nine months ended
     September 30, 1997 have been translated into U.S. dollars using exchange
     rates of $1.59 and $1.63 per British pound sterling, respectively. The pro
     forma adjustments column contains adjustments to convert from U.K. GAAP to
     a U.S. GAAP basis, and to present the effect of purchase accounting related
     to the acquisition of Protean. Certain reclassifications have been made to
     the historical financial statements of Protean to conform with the
     Company's presentation.

(l)  To reclassify restructuring expenses of $975 recorded in accordance with 
     U.K. GAAP into selling, general and administrative expenses. Such expenses,
     while properly recorded during Protean's year ended March 31, 1997, do not
     meet the definition of a restructuring expense under U.S. GAAP and,
     therefore, should be classified as selling, general and administrative
     expenses.
     
(m)  To recognize the effect of accounting for pension costs on a U.S. GAAP
     basis. Pension expense is decreased by $51 and $160 for the year ended
     January 31, 1997 and the nine months ended October 31, 1997, respectively.

(n)  To increase selling, general and administrative expenses by $619 for items 
     accrued as restructuring expenses at March 31, 1997 under U.K. GAAP. These 
     expenses do not meet the definition of a restructuring expense under U.S.
     GAAP and are expenses for the nine months ended October 31, 1997.

(o)  To record amortization expense of $1,415 and $1,061 for the year ended
     January 31, 1997 and the nine months ended October 31, 1997, respectively,
     for goodwill resulting from the excess of the purchase price paid by
     Culligan over the sum of identifiable assets acquired and liabilities
     assumed for the continuing operations of Protean. The amortization period
     for goodwill is 40 years.

(p)  To reverse the Protean earnings recognized by Culligan under the equity
     method of $289 for the nine months ended October 31, 1997.

(q)  To record interest expense of $4,407 and $3,305, reflecting the estimated
     expense for the year ended January 31, 1997 and the nine months ended
     October 31, 1997, respectively, for incremental debt incurred in the
     acquisition of approximately $67,802. Such amount does not include the debt
     that is expected to be paid down with the proceeds from the sale of the
     discontinued operations of Protean.

     The effect of a 1/8 percent change in the interest rate on the $67,802 debt
     incurred in the acquisition of Protean would be approximately $85 for the
     year ended January 31, 1997 and $64 for the nine months ended October 31,
     1997.

(r)  To record the tax effect (at 40%) on all pro forma adjustments except
     goodwill, which is not tax deductible.

(s)  To reverse the $17,000 write-off of in-process research and development
     related to the Ametek acquisition recorded during the nine months ended
     October 31, 1997, as this charge is non-recurring in nature and is not
     representative of the results of continuing operations.
