                                AQUA-CHEM, INC.
                             NOTES TO CONSOLIDATED
                         CONDENSED FINANCIAL STATEMENTS

                                                                               

(1)     In the opinion of Management, the accompanying unaudited financial
        statements of Aqua-Chem, Inc. contain all adjustments which are of a
        normal recurring nature necessary to present fairly the financial
        position as of September 30, 1998, and the results of operations and
        cash flows for the periods indicated. Interim financial results are not
        necessarily indicative of operating results for an entire year.

(2)     Certain notes and other information have been condensed or omitted from
        these interim consolidated condensed financial statements. Therefore,
        these statements should be read in conjunction with the Aqua-Chem, Inc.
        Consolidated Financial Statements as of December 31, 1997 and 1996.

(3)     On July 31, 1997, Aqua-Chem, Inc. ("OLDCO") entered into a definitive
        merger agreement with A-C Acquisition Corp. ("A-C Acquisition"), a 100%
        owned subsidiary of Rush Creek LLC ("Rush Creek"). Rush Creek is a
        Limited Liability Company owned by certain management of OLDCO and
        Whitney Equity Partners L.P. Also on July 31, 1997, A-C Acquisition
        acquired the assets of OLDCO (the "Management Buy-Out") for $125,747,
        which includes $69,196 of liabilities assumed and $5,000 of Series A
        Cumulative Preferred Stock issued to the sellers. The amount paid does
        not include contingent consideration to be paid to the sellers based on
        cumulative earnings of certain operations of Aqua-Chem subsequent to the
        Management Buy-Out. The Management Buy-Out was accounted for by
        Aqua-Chem using the purchase method of accounting.

(4)     The consolidated condensed financial statements for the seven months
        ended July 31, 1997 were prepared using OLDCO's historical basis of
        accounting (the "pre-acquisition basis of accounting"). The consolidated
        condensed financial statements for the two months ended September 30,
        1997 and for the nine months ended September 30, 1998 were prepared
        under a new basis of accounting that reflects the fair values of assets
        acquired and liabilities assumed, the related financing costs and all
        debt incurred in connection with the Management Buy-Out (the
        "post-acquisition basis of accounting"). Accordingly, the accompanying
        financial statements are not comparable in all material respects since
        those financial statements report financial position, results of
        operations, and cash flows of two separate entities.

(5)     Inventories consist of the following:



                                                          September 30,         December 31,
                                                               1998                 1997

                                                               =======             =======


(6)     On June 23, 1998 Aqua-Chem issued $125,000 in unsecured senior
        subordinated notes. The notes carry an interest rate of 11 1/4% and are
        due July 1, 2008. Interest is payable semi-annually beginning January 1,
        1999. Proceeds from the notes were used to repay Aqua-Chem's existing
        debt, to redeem $3,269 of Aqua-Chem's Series A Preferred Stock, to
        acquire substantially all of the assets of National Dynamics Corporation
        ("NDC") (see note (9)), to pay the accrued interest and dividends, fees
        and expenses associated with the foregoing, and for general corporate
        purposes.  The holders of the Series B Preferred Stock elected not to
        require that the Series B Preferred be redeemed in connection with the
        private offering.

        In conjunction with the issuance of the notes and the acquisition of
        NDC, Aqua-Chem entered into a revised $45,000 secured revolving credit
        facility. Borrowings under this facility are made in the form of
        revolving credit notes. These notes bear interest at a rate of either
        eurocurrency plus a factor as defined in the agreement, prime, or
        federal funds rate plus 100 basis points. The revolving credit agreement
        will terminate June 23, 2003. The facility is secured by the assets of
        the Company. At September 30, 1998 there were no borrowings outstanding.
        Among other restrictions, the credit agreement contains covenants
        relating to financial ratios and other limitations, as defined by the


   9


        agreement. As of September 30, 1998, the Company was in compliance with
        these covenants.

(7)     On June 25, 1998 the Board of Directors approved a plan of closure for
        the Greenville, Mississippi facility and the agreement reached with the
        Union representing the facility's production workers. As a result, the
        Company recorded a restructuring charge of $4,720 to operations in the
        nine months ended September 30, 1998. Work currently performed at the
        facility is in the process of being transferred to other Company
        facilities and/or outsourced. The plan will result in the elimination of
        149 positions and closure of the facility within approximately one year
        from the date of approval. The Greenville facility has fixed assets with
        a net book value of $3,800, which includes $1,828 of machinery and
        equipment, $1,846 in lease and leasehold improvements and $126 in
        furniture and fixtures. The Company intends to transfer some of the
        fixed assets to other facilities and will sell or dispose of the
        remaining assets by the closure date. The write down associated with the
        assets to be sold or disposed of results in a restructuring charge of
        $2,921. The remaining charge includes $100 to write down the value of
        the inventory, $1,460 of employee termination benefits and $239 of other
        costs related to post closure upkeep and maintenance of the facility.

(8)     On June 23, 1998, Aqua-Chem acquired substantially all the assets of
        National Dynamics Corporation for $62,591, which includes $14,691 of
        liabilities assumed. The acquisition was accounted for using the
        purchase method of accounting. The total purchase cost was allocated
        first to identified tangible and intangible assets and liabilities based
        upon their respective fair values, with the remainder of $27,932 being
        allocated to goodwill, which will be amortized on a straight-line basis
        over 40 years. The financial statements reflect the preliminary
        estimates of allocating purchase price and may be revised at a later
        date. The Company does not expect the final purchase price allocation to
        be materially different from preliminary estimates. 

(9)     The following information presents pro forma condensed consolidated
        statements of operations assuming OLDCO and National Dynamics
        Corporation had been acquired by Aqua-Chem as of January 1, 1997. Such
        information includes adjustments to reflect additional interest expense
        and depreciation expense, amortization of goodwill and other
        intangibles, a reduction of other expenses to Management Buy-Out-related
        payments being made by OLDCO and the net elimination of employment costs
        of the former owners of National Dynamics Corporation.

(10)    Effective December 31, 1997, Aqua-Chem adopted Statement of Financial
        Accounting Standards No. 130, "Reporting Comprehensive Income" ("SFAS
        No. 130"). This statement establishes standards for reporting and
        display of comprehensive income which includes foreign currency
        translation adjustments accounted for under SFAS No. 52. SFAS No. 130
        requires that an enterprise classify items of other comprehensive income
        by their nature in a financial statement for the period in which they
        are recognized. Aqua-Chem has chosen to disclose comprehensive income in
        the Consolidated Statements of Operations. Prior years have been
        restated to conform to the SFAS No. 130 requirements. Accumulated other
        comprehensive income at September 30, 1998 and December 31, 1997 is
        comprised of only foreign currency translation adjustments. Prior years
        have been restated to conform to the SFAS No. 130 requirements. 

        Statement of Position ("SOP") No. 98-1, "Accounting for the Costs of
        Computer Software Developed or Obtained for Internal Use" was issued by
        The American Institute of Certified Public Accountants in March of 1998
        and is effective for fiscal years beginning after



   10


         December 15, 1998. Aqua-Chem's accounting for costs of computer
         software developed or obtained for internal use is consistent with the
         guidelines established in the SOP and, as a result, Aqua-Chem does not
         anticipate that the adoption of this statement will have a material
         impact on Aqua-Chem's financial position or results of operations.

         In June 1998, the Financial Accounting Standards Board issued Statement
         of Financial Accounting Standards No. 133, Accounting for Derivative
         Instruments and Hedging Activities. The statement establishes
         accounting and reporting standards requiring that every derivative
         instrument ( including certain derivative instruments embedded in other
         contracts) be recorded in the balance sheet as an asset or liability
         measured at its fair value. Statement 133 is effective for fiscal years
         beginning after June 15, 1999. The Company has not determined the
         timing of or method of adoption, but does not anticipate that the
         adoption of this standard will have a material impact on its financial
         statements.

  (11)   In connection with the Management Buy-Out, Aqua-Chem adopted
         the Aqua-Chem, Inc. 1997 Stock Option Plan (the "1997 Plan"), which
         provides for the granting to key employees, directors, and other
         individuals of options to purchase an aggregate of 61,919 shares of
         Aqua-Chem common stock at a purchase price not less than the greater of
         (i) $3.75, or (ii) fair market value as determined by the Plan. Options
         vest primarily based upon Aqua-Chem achieving certain operating results
         or within 7 years from the date of grant. As of September 30, 1998,
         4,000 options have been granted and are outstanding under the 1997
         Plan.

         On August 1, 1998, Aqua-Chem adopted the Aqua-Chem, Inc. 1998 Stock 
         Option Plan (the "1998 Plan"), which provides for the granting to key 
         advisers, consultants and employees options to purchase an aggregate 
         of 61,919 shares of Aqua-Chem common stock at a purchase price of not 
         less than $3.75 nor greater than the market price as determined by the 
         Board of Directors. Options vest primarily in accordance with vesting 
         provisions contained in written agreement with the optionee.  As of 
         September 30, 1998, 15,740.40 options have been granted and are 
         outstanding under the 1998 Plan.

         Under separate agreements from the 1997 Plan and the 1998 Plan, the
         option to purchase 1,725 shares of common stock have been granted to
         two directors of Aqua-Chem. Under the terms of the agreements, the
         option to purchase 600 shares vests one year from the effective date of
         the grant, with the remaining 1,125 options vesting at a rate of 225
         per year commencing on December 31, 1998 and continuing through
         December 31, 2002. These options allow the holder to purchase common
         stock of Aqua-Chem at $3.75 per share, which does not differ
         significantly from fair market value. As of September 30, 1998, no
         options were exercised.

       ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                CONDITION AND RESULTS OF OPERATIONS OF AQUA-CHEM

                The following discussion should be read in conjunction with, and
       is qualified in its entirety by reference to the consolidated condensed
       financial statements of the Company appearing elsewhere in this document.

                On July 31, 1997, certain members of management and a private
       investor acquired the Company from its former owners (the "Management
       Buy-Out"). The financial results of the Company for all periods prior to
       July 31, 1997 reflect the operations of the Company under its prior
       owners. The consolidated financial statements for subsequent periods
       reflect the financial results of the Company under a new basis of
       accounting that reflects the fair values of assets acquired and
       liabilities assumed, the related financing costs, and all debt incurred
       in connection with the Management Buy-Out. Accordingly, the financial
       information for The Company before and after the Management Buy-Out are
       not comparable in all material respects since those financial statements
       report the financial position, results of operations and cash flows of 
       two separate entities.

       THREE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO THREE MONTHS ENDED 
       SEPTEMBER 30, 1997

                Net Sales. Net sales for the three month period ended September
       30, 1998 increased $14.2 million to $66.5 million from $52.3 million.
       $18.2 million of the increase relates to the acquisition of National
       Dynamics as of June 1998. Net sales of Cleaver-Brooks declined $2.4
       million (5.6%) of which approximately 52% of the decrease resulted from
       the sale of the contract machining business in the fourth quarter of 1997
       with the remainder attributable to soft orders during the first two
       quarters of 1998. Water Technologies sales decreased $1.5 million (16.0%)
       during the same time period primarily due to soft orders in the navy
       sector.

                 Gross Margin. Gross margin remained flat at $14.6 million as
       compared to 1997. The gross margin percentage decreased 5.9% to 22.0%
       primarily due to the inclusion of National Dynamics operations for the
       first time in 1998. Margins at National Dynamics reflected an inventory
       write-up of $1.4 million as a result of the acquisition on June 23, 1998.
       Additionally, after adjustment for the inventory write-up, National
       Dynamics' gross margin is 19.2% which is substantially less than
       Aqua-Chem's normal margins without National Dynamics.


                Selling, General and Administrative Expenses. Selling, general
       and administrative expense increased $0.5 million (4.9%) to $11.7
       million. Commissions to independent representatives and to internal sales
       personnel were $0.1 million lower in the current period due to the
       reduced sales volume while post retiree health care costs increased $0.2
       million as a result of an adjustment in 1997 for the recognition of the
       transition obligation at the time of the Management Buy Out. The
       acquisition of National Dynamics in June 1998 increased selling, general
       and administrative expenses $1.4 million which is offset by $1.3 million
       of certain non-recurring expenses related to the Management Buy-Out in
       1997.

                Operating Income. For the reasons set forth above, operating
       income decreased $0.5 million to $2.9 million.

   
                Other Income (Expense).  Other income (expense) for the three
       months ended September 30, 1998 was an expense of $3.5 million as
       compared to an expense of $0.9 million for the same period in 1997,
       resulting in a difference of $2.6 million (283.7%).  This difference is
       primarily due to increased debt issued in conjunction with the Management
       Buy-Out and the Private Offering.
    

       NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO NINE MONTHS ENDED 
       SEPTEMBER 30, 1997
       

                Net Sales. Net sales for the nine month period ended September
       30, 1998 increased $7.2 million to $142.7 million from $135.5 million.
       This increase was primarily attributable to the acquisition of National
       Dynamics Corporation which occurred on June 23, 1998. The National
       Dynamics Division ("National Dynamics") contributed $18.2 million in net
       sales since the date of acquisition. Net sales of Cleaver-Brooks declined
       $12.0 million (10.8%). Approximately 43.3% of the decrease resulted from
       the sale of the contract machining business in the fourth quarter of 1997
       with the remainder attributable to soft orders during the second half of
       1997 through the first quarter of 1998. Water Technologies sales
       increased $1.0 million (4.0%) during the same time period primarily due
       to a large land-based water desalination project.

                Gross Margin. Gross margin declined $0.8 million (2.2%) to $34.9
       million from $35.7 million for the same period in 1997. The gross margin
       percentage decreased 1.9% to 24.5% primarily due to the inclusion of
       National Dynamics operations for the first time in 1998. Margins at
       National Dynamics reflected an inventory write-up of $1.4 million as a
       result of the acquisition on June 23, 1998. Additionally, after
       adjustment for the inventory write-up, National Dynamics' gross margin is
       19.2% which is substantially less than Aqua-Chem's normal margins without
       National Dynamics. Also, depreciation expense was higher in 1998 as a
       result of the step-up in basis of the fixed assets in connection with the
       Management Buy-Out on July 31, 1997.

                Selling, General and Administrative Expenses. Selling, general
       and administrative expense




   12

       declined $1.4 million (4.5%) to $29.2 million. Commissions to independent
       representatives and to internal sales personnel were $0.8 million lower
       in the current period due to the reduced sales volume. The acquisition of
       National Dynamics in June 1998 increased selling, general and
       administrative expenses $1.4 million which is offset by $1.3 million of
       certain non-recurring expenses related to the Management Buy-Out in 1997.

                Restructuring Charges. A restructuring charge of $4.7 million
       was recorded in the current period as a result of the Board of Directors'
       approval of the 1998 Restructuring. The provision included $3.0 million
       to write down the value of certain fixed assets and inventory, $1.5
       million for employee severance and additional workers compensation
       related costs and $0.2 million for other related costs.

                Operating Income. For the reasons set forth above, operating
       income decreased $4.2 million to $1.0 million. Excluding the $4.7 million
       restructuring charge, operating income increased $0.5 million to $5.7
       million compared to $5.2 million for the nine months ended September 30,
       1997. The inclusion of National Dynamic's operations contributed $0.7
       million to operating income.
       
   
                Other Income (Expense).  Other income (expense) for the nine
       months ended September 30, 1998 was an expense of $6.3 million as
       compared to an expense of $1.1 million for the same period in 1997,
       resulting in a difference of $5.1 million (471.3%) $4.9 million of this
       difference is due to increased debt issued in conjunction with the
       Management Buy-Out and the Private Offering.  Additionally, interest
       income declined $0.2 million due to the use of cash-on-hand in
       conjunction with the Management Buy-Out.
    

       LIQUIDITY AND CAPITAL RESOURCES

                Cash used in operating activities was $12.8 million for the nine
       months ended September 30, 1998 compared to cash provided by operating
       activities of $5.3 million for the same period in 1997. The decrease of
       $18.1 million is due primarily to $1.7 million of additional interest
       expense due to the increased debt levels resulting from the issuance of
       $125 million in notes and the subsequent acquisition of National
       Dynamics, $3.0 million decrease in accounts payable, and a decrease in
       accrued expenses of $10.1 million which includes $2.7 million in
       litigation settlement payments, $2.3 million in increased performance
       related incentives and $2.0 of income tax payments.

                Cash used in investing activities was $49.6 million for the nine
       months ended September 30,


   13

       1998 compared to a net use of $53.6 million for the same period in 1997.
       The current period included $47.9 million for the purchase of National
       Dynamics Corporation and capital expenditures of $1.8 million. The prior
       year period included $52.1 million for the Management Buy-Out of the
       Company and $2.8 million of capital expenditures.

                Cash provided by financing activities was $56.6 million for the
       nine months ended September 30, 1998 compared to $41.7 million for the
       same period in 1997. The current period included $125.0 million of
       proceeds from the issuance of notes and advances under the revolving
       credit agreement and repayments of senior and subordinated debt and
       preferred stock of $66.3 million in conjunction with the 11 1/4% notes
       offering. The increase was also offset by deferred financing costs of
       $5.1 million related to the issuance of the notes in the current period.
       The prior year period included $68.2 million of proceeds from senior and
       subordinated debt and the issuance of preferred stock in conjunction with
       the Management Buy-Out. This increase was partially offset by the
       repayment of debt of $25.0 million and deferred financing costs of $2.0
       million related to the Management Buy-Out.

                Management believes that cash generated from operating
       activities together with borrowing availability under the New Credit
       Facility will be adequate to cover the Company's working capital, debt
       service and capital expenditure requirements on a short and long term
       basis. The Company may, however, consider other options available to it
       in connection with funding future working capital and capital expenditure
       needs, including the issuance of additional debt and the issuance of
       equity securities.

                Under the New Credit Facility the Company is required to
       maintain an adjusted consolidated tangible net worth (consolidated
       tangible net worth plus an amount equal to the aggregate outstanding
       principle amount of subordinated debt) of not less than $70 million plus
       (on a cumulative basis) for each fiscal quarter ending on or after June
       23, 1998, the sum of (a) 50% of consolidated net income if positive and
       100% of the cash proceeds of the issuance of any equity interest of the
       Company during such fiscal quarter. In addition, the New Credit Facility
       requires the Company to maintain a fixed charge coverage ratio of not
       less than 1.25 to 1 and a senior funded debt to consolidated EBITDA ratio
       of not more than 3.5 to 1.

                The Indenture prohibits the Company from incurring additional
       Indebtedness unless, on the date of such incurrence and after giving
       effect thereto, the Consolidated Coverage Ratio exceeds 2.0 to 1 if such
       Indebtedness is incurred prior to January 1, 2000, 2.25 to 1 if such
       Indebtedness is incurred on or after January 1, 2000 and prior to January
       1, 2001 or 2.5 to 1 thereafter (the "Coverage Limitation"). As of
       September 30, 1998, the Company could not have incurred any additional
       Indebtedness under the Coverage Limitation.

                The Indenture further provides that, in addition to the
       additional indebtedness which the Company may incur under the Coverage
       Limitation, the Company may incur additional Indebtedness of certain
       types up to certain limitations applicable to each type (the "Basket
       Limitations"). The Basket Limitations are described under "Description of
       the Notes - Certain Covenants - Limitation on Indebtedness." The amount
       of additional Indebtedness which the Company could have incurred as of
       September 30, 1998 under certain of the Basket Limitations is impossible
       to quantify as of the date of this Prospectus because those Basket
       Limitations relate to transactions or other events or conditions that had
       not occurred or did not exist as of such date, and the applicable dollar
       limitations thereunder depend upon the nature of such events or the
       nature and terms of such transactions. Certain of the Basket Limitations
       relate to intercompany transactions and guarantees, which would not
       increase the aggregate amount of additional Indebtedness that may be
       incurred. However, the Company could have incurred approximately $77.3
       million of additional Indebtedness under the remaining Basket Limitations
       on September 30, 1998, including the following: (a) Indebtedness pursuant
       to the New Credit Facility of up to the greater of (i) $45.0 million or
       (ii) the sum of 50% of the book value of inventory and 85% of the book
       value of accounts receivable as of such date (however, the limitation
       under clause (ii) would have been approximately $54.2 million at
       September 30, 1998; this limitation would not have affected the maximum
       amount that could have been borrowed under the New Credit Facility as of
       September 30, 1998 because the maximum amount of the New Credit Facility
       on that date was $45.0 million); (b) Indebtedness by foreign subsidiaries
       not exceeding the sum of (i) 60% of



   14

       the book value of inventory and (ii) 85% of the book value of accounts
       receivable; (c) purchase money Indebtedness not exceeding the greater of
       (i) $20 million or (ii) 5% of the consolidated net worth of the Company;
       and (d) an additional $10 million without regard to the nature or purpose
       of such Indebtedness.

YEAR 2000

     Many computer software applications, hardware and equipment and embedded
chip systems identify dates using only the last two digits of the year. These
products may be unable to distinguish between dates in the year 2000 and dates
in the year 1900. That inability (referred to as the "Year 2000 Issue"), if not
addressed, could cause applications, equipment or systems to fail or provide
incorrect information after December 31, 1999, or when using dates after
December 31, 1999. The Company uses a number of computer software programs,
operating systems, and types of equipment with computer chips in its internal
operations, including applications used in its financial business systems, order
entry and manufacturing systems, manufacturing processes and administrative
functions. The Company also manufactures products that incorporate components
purchased from other manufacturers that contain computer chips. To the extent
that the above listed items contain source code or computer chips that are
unable to interpret appropriately the upcoming calendar year 2000,
distinguishing it from the year 1900, some level of modification or possible
replacement will be necessary.

     STATE OF READINESS - The Company has assessed and continues to assess the
impact of the Year 2000 Issue on its operations. The Company's assessments have
focused on the three major elements of the Year 2000 Issue: IT systems; Non-IT
systems; and third party relationships.

          IT SYSTEMS - Since 1996 the Company has been executing an IT system
upgrade plan, which includes leasing a new mainframe computer at an annual cost
of $0.6 million, and the expansion of and improvements to, its networks and
capital spending on hardware totaling $0.2 million. Additionally, the Company
has spent $1.5 million on new financial systems software, of which $1.3 million
has been capitalized. These systems are replacing software that has been in use
since the early 1980's. The IT system upgrade plan was not undertaken in
response to the Year 2000 Issue, nor was it accelerated due to the Year 2000
Issue.

Of these new financial systems, the general ledger and reporting packages have
been implemented, while the accounts receivable and accounts payable packages
are in the installation phase with a March 1999 targeted completion date.
Management believes these projects are currently on schedule to meet this target
date. The current human resource/payroll system has been upgraded to address the
Year 2000 Issue.

The Company has received written assurances from the manufacturers that the
following hardware and software are Year 2000 compliant as a result of the IT
upgrade plan: mainframe hardware; mainframe systems software; mainframe
operating system; LAN/WAN hardware; LAN/WAN operating systems; LAN/WAN system
software; personal computers and related software; and financial systems
software.

The Company's order entry and manufacturing systems are in the process of being
upgraded to address the Year 2000 Issue. The databases for all these systems
have been expanded and regenerated. Management believes the application programs
for these systems are on schedule to be converted by the end of October, 1998
with testing to occur until production turnover in March, 1999. Other non-Year
2000 IT efforts have not been materially delayed or impacted by Year 2000
initiatives.

          NON-IT SYSTEMS - The Company has reviewed all of its communication 
systems (phone and data transmission systems), fax machines, photocopiers,
postage machines, elevators, HVAC systems, security systems and shop floor
equipment with the manufacturers or vendors of those systems and equipment and
has received verbal assurances that these systems are Year 2000 compliant.
Written certifications of Year 2000 compliance for these systems has been
requested from the manufacturers or vendors. The Company is currently reviewing
the responses it has received to date and has sent a follow up letter to any
manufacturers or vendors who have not responded.

          THIRD PARTY RELATIONSHIPS - All of the Company's suppliers of raw
materials, components, and other goods and services have been sent a
questionnaire regarding their Year 2000 compliance and their plans to be Year
2000 compliant. Over half of the suppliers contacted have responded. A follow up
letter has been sent to those suppliers who have yet to respond. For those
remaining suppliers who do not respond to this questionnaire, or who do not have
a Year 2000 compliance plan in place, the Company has identified alternative
suppliers and will use an alternative supplier who has certified that it is Year
2000 compliant. For all suppliers of equipment containing computer chips which
are incorporated into the Company's products, the Company has received written
assurance that this equipment is Year 2000 compliant.
   15

     COSTS TO ADDRESS THE COMPANY'S YEAR 2000 ISSUE - Costs incurred by the
Company to date to address the Year 2000 Issue, excluding the IT system upgrade
costs, are approximately $0.1 million. The Company estimates total costs
remaining to be incurred prior to the year 2000 range from $0.2 million to $0.3
million. Maintenance or modification costs will be expensed as incurred, while
the costs of new software will be capitalized and amortized over the software's
useful life. These costs will be funded from operating cash flows.

     RISKS AND CONTINGENCY PLANS - Although the Company believes its efforts
will adequately address its Year 2000 Issue internally, it is possible that the
Company will be adversely affected by problems encountered by its vendors or
suppliers. Despite any vendor's or supplier's certification regarding Year 2000
compliance, there can be no assurance that the vendor's or supplier's ability to
provide goods and services will not be adversely affected by the Year 2000
Issue. The most likely worst case scenario would be that a failure by the
Company or one or more of its vendors or suppliers to adequately and timely
address the Year 2000 Issue, interrupts manufacturing of the Company's products
for a undeterminable period of time. The Company has identified and will
continue to identify alternative vendors should a vendor's ability to meet the
Company's raw material and supply requirements be impacted by the Year 2000
Issue. While the Company believes it can minimize the impact of such
non-compliance through the use of these alternative vendors, a disruption in
production could have a material adverse impact on the Company. The Company does
not currently expect to develop a formal contingency plan.

GENERAL

     The costs of the Company's efforts to address the Year 2000 Issue and the
dates on which the Company believes it will complete such efforts are based upon
management's best estimates, which were derived using numerous assumptions
regarding future events. There can be no assurance that these estimates will
prove to be accurate, and actual results could differ materially from those
currently anticipated. Specific factors that could cause such material
differences include, but are not limited to, the Company's ability to identify,
assess, remediate and test relevant computer codes and embedded technology, the
Company's reliance on third-party assurances and the variability of definitions
of " Year 2000 compliance" which may be used by such third parties, and similar
uncertainties.
