NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         BASIS OF PRESENTATION AND DESCRIPTION OF BUSINESS MPW Industrial
Services Group, Inc. and its subsidiaries (the "Company") provide
technically-based services, including industrial cleaning and facility
maintenance, industrial container cleaning and industrial process water
purification. Such services are primarily provided at customer facilities. The
Company serves customers in numerous industries including automotive,
manufacturing, steel, utility, pulp and paper, chemical and construction
primarily throughout the United States and Canada.

         The accompanying unaudited consolidated financial statements presented
herein have been prepared by the Company and reflect all adjustments of a normal
recurring nature that are, in the opinion of management, necessary for a fair
presentation of financial results for the three and nine months ended March 31,
2003 and 2002, respectively, in accordance with generally accepted accounting
principles for interim financial reporting and pursuant to Article 10 of
Regulation S-X. Certain footnote disclosures normally included in financial
statements prepared in accordance with generally accepted accounting principles
have been condensed or omitted pursuant to such rules and regulations. These
interim consolidated financial statements should be read in conjunction with the
Company's Annual Report on Form 10-K for the year ended June 30, 2002 ("Annual
Report"). The results of operations for the three and nine months ended March
31, 2003 and 2002, respectively, are not necessarily indicative of the results
for the full year.

         COMPREHENSIVE INCOME (LOSS) Statement of Financial Accounting Standards
("SFAS") No. 130, Reporting Comprehensive Income, requires that an enterprise
report the change in its equity during the period from non-owner sources as
other comprehensive income (loss). The Company has evaluated the statement and
determined that the only items in addition to net income (loss) that would be
included in comprehensive income (loss) are the foreign currency translation
adjustment, the mark-to-market adjustment on interest rate swaps and the
Company's share of the comprehensive loss of its investment in affiliate.
Comprehensive income for the three months ended March 31, 2003 and 2002 was $0.6
million and $1.9 million, respectively. Comprehensive income (loss) for the nine
months ended March 31, 2003 and 2002 was $(2.1) million and $2.4 million,
respectively.

         GOODWILL AND OTHER INTANGIBLES Effective July 1, 2002, the Company
adopted SFAS No. 142, Goodwill and Other Intangible Assets. Under SFAS No. 142,
goodwill and other intangible assets deemed to have indefinite lives are no
longer amortized but are subject to annual impairment tests. Other intangible
assets with identifiable definite lives continue to be amortized over their
useful lives. SFAS No. 142 requires a two-step process for impairment testing of
goodwill. The first step identifies indications of impairment, while the second
step, if necessary, measures the amount of the impairment, if any. The Company
was required to perform a transitional impairment test of goodwill within the
first six months of fiscal 2003 and an annual impairment test thereafter or upon
the occurrence of certain triggering events as defined by SFAS No. 142. The
Company will perform its annual impairment test during the fourth quarter of
each year.

         The Company completed step one of the transitional impairment test
during the second quarter of fiscal 2003 for each of its reporting units. The
Company used discounted cash flow and market comparison methodologies to
determine the fair value of the Company's reporting units. As a result of step
one of the transitional impairment test, it was determined that the Industrial
Cleaning and Facility Maintenance reporting unit had no impairment in connection
with its reported goodwill; however, the fair values of the Industrial Container
Cleaning reporting unit and the medical and laboratory water purification
reporting unit of the Industrial Water Process Purification segment ("WTW") were
determined to be less than the book values of these reporting units.

          Based on the results of step two of the transitional impairment test,
the Company recorded a $2.3 million, net of tax of $1.6 million, transitional
impairment loss in the Industrial Container Cleaning reporting unit and a $0.5
million, net of tax of $0.3 million, transitional impairment loss in the WTW
reporting unit. These changes were recorded as a cumulative effect of a change
in accounting principle as of July 1, 2002 and primarily reflect a decline in
operating results largely due to the economic downturn that has affected many of
the customers that these reporting units serve.

         STOCK OPTIONS Effective January 1, 2003, the Company adopted the
disclosure requirements of SFAS No. 148, Accounting for Stock-Based Compensation
- Transition and Disclosure. This Statement amends SFAS No. 123, Accounting for
Stock-Based Compensation, to provide alternative methods of transition to SFAS
No. 123's fair value method of accounting for stock-based employee compensation
and amends the disclosure provisions of SFAS No. 123 and Accounting Principles
Board ("APB") Opinion No. 28, Interim Financial Reporting, to require disclosure
in the summary of significant accounting policies of the effects of an entity's
accounting policy with respect to stock-based employee compensation on reported
net income and earnings per share in annual and interim financial statements.

         As of March 31, 2003, the Company has two stock-based compensation
plans, which are described in detail in the annual report on Form 10-K for the
year ended June 30, 2002. The Company accounts for these plans under the
recognition and measurement principles of APB No. 25, Accounting for Stock
Issued to Employees, and related interpretations. No stock-based compensation
cost is reflected in net income (loss), as all options granted under these plans
had an exercise price equal to the market value of the underlying common stock
on the date of grant. The following table illustrates the effect on net income
(loss) and net income (loss) per share if the Company had applied the fair value
recognition provisions of SFAS No. 123.

         USE OF ESTIMATES The preparation of financial statements in conformity
with accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the amounts
reported in the accompanying consolidated financial statements. Actual results
could differ from those estimates.

         EFFECT OF RECENT ACCOUNTING PRONOUNCEMENTS In April 2003, the Financial
Accounting Standards Board issued SFAS No. 149, Amendment of Statement 133 on
Derivative Instruments and Hedging Activities. This Statement amends and
clarifies accounting for derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities under SFAS
No. 133, Accounting for Derivative Instruments and Hedging Activities. The
Statement clarifies under what circumstances a contract with an initial net
investment meets the characteristic of a derivative as discussed in SFAS No.
133. In addition, it clarifies when a derivative contains a financing component
that warrants special reporting in the statement of cash flows. SFAS No. 149
also amends certain other existing pronouncements. Those changes will result in
more consistent reporting of contracts that are derivatives in their entirety or
that contain embedded derivatives that warrant separate accounting. This
Statement is effective for contracts entered into or modified after June 30,
2003 and for hedging relationships designated after June 30, 2003. Management
does not expect adoption of this Statement to have a material impact on the
Company's consolidated financial statements.

NOTE 3.  INVESTMENT IN AFFILIATE

         During the first quarter of fiscal 2003, the Company invested
approximately $0.4 million in Pentagon Technologies Group, Inc. ("Pentagon").
Subsequent to March 31, 2003, the Company funded its remaining investment
commitment of approximately $0.1 million.

         The Company's equity in loss of affiliate of $0.3 million for the
quarter ended March 31, 2003 exceeds the Company's percentage share in the net
loss recorded by Pentagon for the same period due to adjustments to Pentagon's
financial statements for its fiscal year ended December 31, 2002 reported
subsequent to the Company's filing of its Form 10-Q for the period ended
December 31, 2002. These adjustments are included in Pentagon's summarized
operating data for the nine months ended March 31, 2003.

</TABLE>

         A significant amount of Pentagon's total assets represent goodwill.
Under the equity method of accounting, the Company's recorded investment in
Pentagon would be affected if Pentagon were to record an impairment charge under
the provisions of SFAS No. 142. The Company will closely monitor its investment
in Pentagon and it is possible that continued declines in Pentagon's operating
results could also in the near term materially affect the Company's recorded
investment in Pentagon.

NOTE 4. LONG-TERM DEBT

         The Company currently has two pay-fixed interest rate swap agreements
as a hedge against the interest rate risk associated with borrowing at a
variable rate, which mature in June 2003. The objective of the hedge is to
eliminate the variability of cash flows related to interest rate payments on
$20.0 million of variable rate debt. The swap agreements have a notional amount
of $10.0 million each and effectively lock in a portion of the Company's
variable rate revolving credit liability at fixed rates of 4.93% and 4.98%,
respectively plus the Company's applicable margin of 2.25%. These swap
agreements are accounted for as cash flow hedges, as defined under SFAS No. 133.
The Company adjusts the pay-fixed interest rate swaps to current market values
through other comprehensive income (loss). The Company anticipates that these
contracts will continue to be effective. The gain/(loss) deferred in accumulated
comprehensive income (loss) will be recognized immediately in earnings if the
contracts are no longer effective or the forecasted transactions are not
expected to occur.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                   (UNAUDITED)


         In March 2003, the Company entered into two forward rate locking
pay-fixed interest rate swap agreements as a hedge against the interest rate
risk associated with borrowing at a variable rate, which are effective beginning
June 2003 and mature in June 2006. The objective of the hedge is to eliminate
the variability of cash flows related to interest rate payments on $20.0 million
of variable rate debt. The swap agreements have a notional amount of $10.0
million each and effectively lock in a portion of the Company's variable rate
revolving credit liability at fixed rates of 2.61% and 2.80%, respectively, plus
the Company's applicable margin. These swap agreements are accounted for as cash
flow hedges, as defined under SFAS No. 133. The Company adjusts the pay-fixed
interest rate swaps to current market values through other comprehensive income
(loss). The Company anticipates that these contracts will continue to be
effective. The gain/(loss) deferred in accumulated comprehensive income (loss)
will be recognized immediately in earnings if the contracts are no longer
effective or the forecasted transactions are not expected to occur.

                                   (UNAUDITED)


         Options to purchase 1,735,550 and 1,417,053 shares of common stock at a
weighted average price of $4.70 and $6.14 per share were outstanding during the
three months ended March 31, 2003 and 2002, respectively, but were not included
in the computation of diluted earnings per share because the exercise price of
the options was greater than the average market price of the shares, therefore,
the effect would be antidilutive. Options to purchase 1,431,050 and 1,820,812
shares of common stock at a weighted average price of $5.32 and $4.78 per share
were outstanding during the nine months ended March 31, 2003 and 2002,
respectively, but were not included in the computation of diluted earnings per
share because the options' exercise price was greater than the average market
price of the common shares, therefore, the effect would be antidilutive.

NOTE 6. RELATED PARTY TRANSACTIONS

         The Company rents certain land, property, buildings and equipment from
entities controlled by its principal shareholder and Chief Executive Officer
under long-term lease agreements and other arrangements. Total expenses related
to these leases and other arrangements were $0.5 million and $0.4 million for
the three months ended March 31, 2003 and 2002, respectively, and $1.5 million
and $1.4 million for the nine months ended March 31, 2003 and 2002,
respectively.

         Subsequent to March 31, 2003, the Company entered into a one-year
agreement to rent an aircraft from Miramonte Aviation, LLC, an entity controlled
by its principal shareholder and Chief Executive Officer, for an annual lease
payment of $420,000, payable monthly, plus applicable state and local taxes.
This lease terminates on May 12, 2004 and includes four one-year options to
renew at the lessor's option upon 30 days written notice.

         The Company provides, from time to time, certain fabrication-type
services to Pro-Kleen Industrial Services, Inc. ("Pro-Kleen"), a portable
sanitation services company wholly-owned by the Company's principal shareholder
and Chief Executive Officer. The Company bills Pro-Kleen for services it
renders. The amount of such billings were not significant for the three months
ended March 31, 2003, were $0.1 million for the three months ended March 31,
2002 and were approximately $0.2 million and $0.1 million for the nine months
ended March 31, 2003 and 2002, respectively. These billings represent
reimbursement for the use of parts and supplies and the use of certain of the
Company's employees on certain projects as requested by Pro-Kleen. These
reimbursements by Pro-Kleen are generally treated as an offset to supplies,
repairs and maintenance or labor expense.

NOTE 7. SEGMENT REPORTING

         Summarized financial information for the Company's reportable segments
is set forth below (in thousands). Corporate expenses are fully allocated to the
segments. Corporate support services that are attributable to the operating
segments are allocated based on each segment's percentage of total revenues.
General corporate expenses are allocated to each segment equally.

THREE MONTHS ENDED MARCH 31, 2003 COMPARED TO THREE MONTHS ENDED MARCH 31, 2002

         Revenues. Revenues increased 6.7% to $24.5 million in the third quarter
of fiscal 2003 from $23.0 million in the prior year period. The increase was
primarily the result of the start-up of new branches in the Industrial Cleaning
and Facility Maintenance segment and a new facility in the Industrial Water
Process Purification segment.

                                       14
<PAGE>

         Cost of Services. Total cost of services was $18.1 million for the
three months ended March 31, 2003 compared to $17.5 million for the three months
ended March 31, 2002. Cost of services as a percentage of revenue decreased to
73.9% in the third quarter of fiscal 2003 from 76.3% in the prior year period.
This decrease was primarily driven by improved operating efficiencies primarily
in labor management and lower depreciation expense, offset slightly by increased
fuel costs.

         Selling, General and Administrative Expenses. Selling, general and
administrative expenses as a percentage of revenue decreased to 17.8% in the
third quarter of fiscal 2003 from 18.9% in the prior year period. However, total
selling, general and administrative expenses increased slightly to $4.4 million
for the three months ended March 31, 2003 from $4.3 million for the three months
ended March 31, 2002. The increase was primarily the result of additional sales
and business development personnel, increased repair and maintenance costs and
increased bad debt expense related to a customer who filed for bankruptcy, which
were offset by income received from a contract settlement and a decrease in
amortization expense as a result of the Company's adoption of Statement of
Financial Accounting Standard ("SFAS") No. 142, Goodwill and Other Intangible
Assets.

         Income from Operations. Income from operations was $2.0 million for the
three months ended March 31, 2003 compared to $1.1 million for the three months
ended March 31, 2002. As a percentage of revenue, income from operations
increased to 8.3% in the third quarter of fiscal 2003 from 4.8% in the prior
year period primarily related to the factors discussed above.

         Interest Expense. Interest expense decreased to $0.5 million in the
third quarter of fiscal 2003 from $0.6 million in the prior year period. The
decrease was primarily due to lower average outstanding borrowings and lower
interest rates.

         Provision for Income Taxes. The provision for income taxes for the
three months ended March 31, 2003 and 2002 reflects an effective rate of 42% and
2%, respectively. The provision for income taxes for the three months ended
March 31, 2002 includes a non-recurring benefit of $0.2 million related to a
reduction in the Company's valuation allowance against the Company's deferred
tax asset for capital loss carry-forwards associated with the Company's July
2001 sale of Pentagon Technologies Group, Inc. ("Pentagon") stock. The reduction
in the valuation allowance resulted from 2002 developments related to the
finalization of the Company's fiscal 2001 income tax return.

         Discontinued Operations. On June 4, 2001 the Company closed on the sale
of the Industrial Products and Services ("Filter") group to CLARCOR Inc., a
filter manufacturer. Income from discontinued operations for the three months
ended March 31, 2002 consists solely of a tax benefit related to a reduction in
the valuation allowance against the Company's deferred tax asset for capital
loss carry-forwards associated with the sale of the Filter group. These tax
benefits resulted from fiscal 2002 developments related to the finalization of
the Company's fiscal 2001 income tax return.

NINE MONTHS ENDED MARCH 31, 2003 COMPARED TO NINE MONTHS ENDED MARCH 31, 2002

         Revenues. Revenues increased 6.2% to $73.2 million in the first nine
months of fiscal 2003 from $68.9 million in the prior year period. The increase
was primarily the result of a large project performed by the Company's union
subsidiary, the start-up of new branches and increased work with paper, steel
and construction customers in the Industrial Cleaning and Facility Maintenance
segment and a new facility in the Industrial Water Process Purification segment.

         Cost of Services. Total cost of services was $56.0 million for the nine
months ended March 31, 2003 compared to $50.1 million for the nine months ended
March 31, 2002. Cost of services as a percentage of revenue increased to 76.6%
in the first nine months of fiscal 2003 from 73.9% in the prior year period. The
increase was primarily related to additional investments in the business related
to the start-up of new branches, heavier reliance on sub-contract services and
increased repair, maintenance and fuel costs, slightly offset by improved
operating efficiencies primarily in labor management.

         Selling, General and Administrative Expenses. Selling, general and
administrative expenses as a percentage of revenue decreased to 18.6% for the
first nine months of fiscal 2003 from 19.4% in the prior year period. However,
total selling, general and administrative expenses were $13.7 million and $13.4
million for the nine months ended March 31, 2003 and 2002, respectively. The
increase was primarily the result of additional sales and business development
personnel, increased repair and maintenance costs and increased bad debt expense
related to a customer who filed for bankruptcy, which were offset by income
received from a contract settlement and a decrease in amortization expense as a
result of the Company's adoption of Statement of Financial Accounting Standard
("SFAS") No. 142, Goodwill and Other Intangible Assets.

         Income from Operations. Income from operations was $3.5 million for the
nine months ended March 31, 2003 compared to $4.6 million for the nine months
ended March 31, 2002. As a percentage of revenue, income from operations
decreased to 4.8% in the first nine months of fiscal 2003 from 6.7% in the prior
year period primarily related to the factors discussed above.

         Interest Expense. Interest expense decreased to $1.5 million in the
first nine months of fiscal 2003 from $2.0 million in the prior year period. The
decrease was primarily due to lower average outstanding borrowings and lower
interest rates.

         Provision for Income Taxes. The provision for income taxes for the nine
months ended March 31, 2003 and 2002 reflects an effective rate of 42% and 36%,
respectively. The provision for income taxes for the nine months ended March 31,
2002 includes a non-recurring benefit of $0.2 million related to a reduction in
the Company's valuation allowance against the Company's deferred tax asset for
capital loss carry-forwards associated with the Company's July 2001 sale of
Pentagon Technologies Group, Inc. ("Pentagon") stock. The reduction in the
valuation allowance resulted from 2002 developments related to the finalization
of the Company's fiscal 2001 income tax return.

         Discontinued Operations. On June 4, 2001 the Company closed on the sale
of the Industrial Products and Services ("Filter") group to CLARCOR Inc., a
filter manufacturer. Income from discontinued operations for the nine months
ended March 31, 2002 consists solely of a tax benefit related to a reduction in
the valuation allowance against the Company's deferred tax asset for capital
loss carry-forwards associated with the sale of the Filter group. These tax
benefits resulted from fiscal 2002 developments related to the finalization of
the Company's fiscal 2001 income tax return.


RELATED PARTY TRANSACTIONS

         The Company rents certain land, property, buildings and equipment from
entities controlled by its principal shareholder and Chief Executive Officer
under long-term lease agreements and other arrangements. Total expenses related
to these leases and other arrangements were $0.5 million and $0.4 million for
the three months ended March 31, 2003 and 2002, respectively, and $1.5 million
and $1.4 million for the nine months ended March 31, 2003 and 2002,
respectively.

         Subsequent to March 31, 2003, the Company entered into a one-year
agreement to rent an aircraft from Miramonte Aviation, LLC, an entity controlled
by its principal shareholder and Chief Executive Officer, for an annual lease
payment of $420,000, payable monthly, plus applicable state and local taxes.
This lease terminates on May 12, 2004 and includes four one-year options to
renew at the lessor's option upon 30 days written notice.

         The Company provides, from time to time, certain fabrication-type
services to Pro-Kleen Industrial Services, Inc. ("Pro-Kleen"), a portable
sanitation services company wholly-owned by the Company's principal shareholder
and Chief Executive Officer. The Company bills Pro-Kleen for services it
renders. The amount of such billings were not significant for the three months
ended March 31, 2003 and $0.1 million for the three months ended March 31, 2002
and were approximately $0.2 million and $0.1 million for the nine months ended
March 31, 2003 and 2002, respectively. These billings represent reimbursement
for the use of parts and supplies and the use of certain of the Company's
employees on certain projects as requested by Pro-Kleen. These reimbursements by
Pro-Kleen are generally treated as an offset to supplies, repair and maintenance
or labor expense.


INVESTMENT IN AFFILIATE

         The Company holds approximately a 22% interest in Pentagon Technologies
Group, Inc. ("Pentagon"), and accounts for its investment in Pentagon under the
equity method of accounting. The Company's investment and proportionate share of
earnings (loss) in Pentagon are classified in the financial statements as
"investment in affiliate" and "equity in earnings (loss) of affiliate,"
respectively. A significant amount of Pentagon's total assets represent
goodwill. Under the equity method of accounting, the Company's recorded
investment in Pentagon would be affected if Pentagon were to record an
impairment charge under the provisions of SFAS No. 142, Goodwill and Other
Intangible Assets. The Company will closely monitor its investment in Pentagon
and it is possible that continued declines in Pentagon's operating results could
also in the near term materially affect the Company's recorded investment in
Pentagon.

         Subsequent to March 31, 2003, the Company funded its remaining
investment committment of $0.1 million in Pentagon.

SUBSEQUENT EVENTS

         In addition to the subsequent events discussed in the preceding
Related Party Transactions and Investment in Affiliate sections, subsequent to
March 31, 2003, the Company entered into an agreement committing to purchase
land and a building for $0.6 million in August 2003.

LIQUIDITY AND CAPITAL RESOURCES

         As of March 31, 2003, the Company had cash of $0.3 million and working
capital of $8.0 million. Cash provided by operating activities was $8.1 million
for the nine months ended March 31, 2003, while cash used for investing
activities was $5.4 million. The cash used for investing activities included an
additional investment of approximately $0.4 million in Pentagon Technologies
Group, Inc. Subsequent to March 31, 2003, the Company funded its remaining
investment commitment of approximately $0.1 million.

         In June 2002, the Company entered into a new credit agreement with its
principal banks (the "Credit Facility"). The Credit Facility provides the
Company with $35.0 million of revolving credit availability for a three-year
period and a $6.0 million three-year term loan to be repaid in quarterly
installments of $0.3 million. As of March 31, 2003, there was $40.1 million
available for general corporate purposes. The Credit Facility is subject to two
one-year extensions by the banks at the request of the Company.

         The Credit Facility is secured by substantially all of the Company's
assets. Under the terms of the Credit Facility, the entire $40.1 million is
available for general corporate purposes, including working capital, capital
expenditures and acquisitions. Borrowings under the Credit Facility currently
bear interest at the Eurodollar market rate plus the applicable margin of 2.25%.
The Company also pays a commitment fee of .45% for unused portions of the Credit
Facility. The interest rate is subject to change based on interest rate formulas
tied to the ratio of consolidated funded debt to earnings before interest,
taxes, depreciation and amortization. Availability of borrowing is subject to
the maintenance of a minimum level of tangible net worth, certain levels of debt
service coverage and maintenance of a specific ratio of funded debt to earnings
before interest, taxes, depreciation and amortization. As of March 31, 2003,
outstanding borrowings under the Credit Facility were $24.5 million.

         The Company currently has two pay-fixed interest rate swap agreements
as a hedge against the interest rate risk associated with borrowing at a
variable rate, which mature in June 2003. The objective of the hedge is to
eliminate the variability of cash flows related to interest rate payments on
$20.0 million of variable rate debt. The swap agreements have a notional amount
of $10.0 million each and effectively lock in a portion of the Company's
variable rate revolving credit liability at fixed rates of 4.93% and 4.98%,
respectively plus the Company's applicable margin of 2.25%. These swap
agreements are accounted for as cash flow hedges, as defined under SFAS No. 133,
Accounting for Derivative and Hedging Activities. The Company adjusts the
pay-fixed interest rate swaps to current market values through other
comprehensive income (loss). The Company anticipates that these contracts will
continue to be effective. The gain/(loss) deferred in accumulated comprehensive
income (loss) will be recognized immediately in earnings if the contracts are no
longer effective or the forecasted transactions are not expected to occur.

         In March 2003, the Company entered into two forward rate locking
pay-fixed interest rate swap agreements as a hedge against the interest rate
risk associated with borrowing at a variable rate, which are effective beginning
June 2003 and mature in June 2006. The objective of the hedge is to eliminate
the variability of cash flows related to interest rate payments on $20.0 million
of variable rate debt. The swap agreements have a notional amount of $10.0
million each and effectively lock in a portion of the Company's variable rate
revolving credit liability at fixed rates of 2.61% and 2.80%, respectively plus
the Company's applicable margin. These swap agreements are accounted for as cash
flow hedges, as defined under SFAS No. 133. The Company anticipates that these
contracts will continue to be effective. The gain/(loss) deferred in accumulated
comprehensive income (loss) will be recognized immediately in earnings if the
contracts are no longer effective or the forecasted transactions are not
expected to occur.

CRITICAL ACCOUNTING POLICIES

         In December 2001, the SEC issued Financial Reporting Release No. 60,
Cautionary Advice Regarding Disclosure About Critical Accounting Policies ("FR
60"), suggesting companies provide additional disclosure and commentary on those
accounting policies considered most critical. FR 60 considers an accounting
policy to be critical if it is important to the Company's financial condition
and results, and requires significant judgment and estimates on the part of
management in its application. The Company's critical accounting policies are
described in Item 7. "Management's Discussion and Analysis of Financial
Condition and Results of Operations" within the Annual Report on Form 10-K for
the year ended June 30, 2002. In addition, a summary of all of the Company's
significant accounting policies, including critical accounting policies, is
included in Note 1 of the Notes to Consolidated Financial Statements in the
Annual Report on Form 10-K for the year ended

                                       17
<PAGE>

June 30, 2002. No changes were made to the Company's critical accounting
policies during the nine months ended March 31, 2003 except as indicated in the
following section.


EFFECT OF RECENT ACCOUNTING PRONOUNCEMENTS

         Effective July 1, 2002, the Company adopted SFAS No. 142, Goodwill and
Other Intangible Assets. Under SFAS No. 142, goodwill and other intangible
assets deemed to have indefinite lives are no longer amortized but are subject
to annual impairment tests. Other intangible assets with identifiable definite
lives continue to be amortized over their useful lives. SFAS No. 142 requires a
two-step process for impairment testing of goodwill. The first step identifies
indications of impairment, while the second step, if necessary, measures the
amount of the impairment, if any. The Company was required to perform a
transitional impairment test of goodwill within the first six months of fiscal
2003 and an annual impairment test thereafter or upon the occurrence of certain
triggering events as defined by SFAS No. 142. The Company will perform its
annual impairment test during the fourth quarter of each year.

         The Company completed step one of the transitional impairment test
during the second quarter of fiscal 2003 for each of its reporting units. The
Company used discounted cash flow and market comparison methodologies to
determine the fair value of the Company's reporting units. As a result of step
one of the transitional impairment test, it was determined that the Industrial
Cleaning and Facility Maintenance reporting unit had no impairment in connection
with its reported goodwill; however, the fair values of the Industrial Container
Cleaning reporting unit and the medical and laboratory water purification
reporting unit of the Industrial Water Process Purification segment ("WTW") were
determined to be less than the book values of these reporting units.

          Based on the results of step two of the transitional impairment test,
the Company recorded a $2.3 million, net of tax of $1.6 million, transitional
impairment loss in the Industrial Container Cleaning reporting unit and a $0.5
million, net of tax of $0.3 million, transitional impairment loss in the WTW
reporting unit. These changes were recorded as a cumulative effect of a change
in accounting principle as of July 1, 2002 and primarily reflect a decline in
operating results largely due to the economic downturn that has affected many of
the customers that these reporting units serve.

         Effective January 1, 2003, the Company adopted the disclosure
requirements of SFAS No. 148, Accounting for Stock-Based Compensation -
Transition and Disclosure. This Statement amends SFAS No. 123, Accounting for
Stock-Based Compensation, to provide alternative methods of transition to SFAS
No. 123's fair value method of accounting for stock-based employee compensation
and amends the disclosure provisions of SFAS No. 123 and Accounting Principles
Board ("APB") Opinion No. 28, Interim Financial Reporting, to require disclosure
in the summary of significant accounting policies of the effects of an entity's
accounting policy with respect to stock-based employee compensation on reported
net income and earnings per share in annual and interim financial statements.

         In April 2003, the Financial Accounting Standards Board issued SFAS No.
149, Amendment of Statement 133 on Derivative Instruments and Hedging
Activities. This Statement amends and clarifies accounting for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities under SFAS No. 133, Accounting for
Derivative Instruments and Hedging Activities. The Statement clarifies under
what circumstances a contract with an initial net investment meets the
characteristic of a derivative as discussed in SFAS No. 133. In addition, it
clarifies when a derivative contains a financing component that warrants special
reporting in the statement of cash flows. SFAS No. 149 also amends certain other
existing pronouncements. Those changes will result in more consistent reporting
of contracts that are derivatives in their entirety or that contain embedded
derivatives that warrant separate accounting. This Statement is effective for
contracts entered into or modified after June 30, 2003 and for hedging
relationships designated after June 30, 2003. Management does not expect
adoption of this Statement to have a material impact on the Company's
consolidated financial statements.

INFLATION

         The effects of inflation on the Company's operations were not
significant during the periods presented in the Consolidated Financial
Statements.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         The Company is exposed to certain market risks from transactions that
are entered into during the normal course of business. The Company has not
entered into derivative financial instruments for trading purposes. The
Company's primary market risk exposure relates to interest rate risk. The
Company's revolving credit facility, which is subject to a variable rate of
interest based on the Eurodollar rate, had a balance of $24.5 million at March
31, 2003. The Company has hedged its exposure to changes in interest rates by
fixing its rate of interest on $20.0 million of its variable rate revolving
credit facility through an interest rate swap agreement. Assuming borrowings at
March 31, 2003, a one hundred basis point change in interest rates would impact
interest expense by approximately $45,000 per year.

ITEM 4.  CONTROLS AND PROCEDURES

         (a)  Evaluation of disclosure controls and procedures.

              The Company's chief executive officer and chief financial officer,
              after evaluating the effectiveness of the Company's "disclosure
              controls and procedures" (as defined in the Securities Exchange
              Act of 1934 Rules 13a-14(c) and 15d-14(c)) as of a date (the
              "Evaluation Date") within 90 days before the filing date of this
              quarterly report, have concluded that as of the Evaluation Date,
              the Company's disclosure controls and procedures were effective
              and designed to ensure that material information relating to the
              Company and the Company's consolidated subsidiaries would be made
              known to them by others within those entities.

              It should be noted that the design of any system of controls is
              based in part upon certain assumptions about the likelihood of
              future events and there can be no assurance that any design will
              succeed in achieving its stated goals under all potential future
              conditions, regardless how remote. In addition, a control system,
              no matter how well conceived and operated, can provide only
              reasonable, not absolute, assurances that the objectives of the
              control system are met. Therefore, the Company does not expect
              these disclosure controls to prevent all error and fraud.

         (b)  Changes in internal controls.

              There were no significant changes in the Company's internal
              controls or in other factors that could significantly affect those
              controls subsequent to the Evaluation Date.
