                                   (Unaudited)

NOTE 1.  BASIS OF PRESENTATION

         MPW Industrial Services Group, Inc. (the "Company") is an industrial
services firm that provides industrial cleaning and facility support services,
industrial process water purification, industrial air filtration services and
other specialized services. Such services are typically provided at customer
facilities. The Company also operates a process facility for industrial
container cleaning. The Company's principal customers are large industrial
facilities in the automotive, electric power, chemical, pulp and paper, steel,
transportation, aerospace and other heavy manufacturing industries. The Company
provides services primarily in the Midwestern and Southeastern United States.

         The unaudited consolidated financial statements include the accounts of
the Company including, but not limited to, (i) MPW Industrial Services, Inc.
("MPW"), (ii) Weston Engineering, Inc. ("Weston"), (iii) ESI International, Inc.
and ESI North, Limited (collectively "ESI International") from the effective
date of acquisition, October 1, 1997 and (iv) Aquatech Environmental, Inc.
("Aquatech"), which was 70% owned by the Company until December 5, 1997, at
which time the Company purchased the remaining minority shareholders' interests
of Aquatech, and it became wholly-owned. The minority shareholders' interests in
the equity and net income of Aquatech are presented separately in the
accompanying unaudited consolidated financial statements for the period through
December 4, 1997. All material intercompany transactions and balances have been
eliminated in consolidation.

         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 six months ended December
31, 1996 and 1997, 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 audited consolidated
financial statements contained in the Company's Registration Statement on Form
S-1 (File No. 333-36887) ("Registration Statement"). The results of operations
for the three and six months ended December 31, 1996 and 1997 are not
necessarily indicative of the results for the full year (see Note 9 for further
information regarding fluctuations in quarterly results).

         The preparation of the financial statements in conformity with
generally accepted accounting principles 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.

NOTE 2.  ACQUISITION OF ESI INTERNATIONAL

         Effective October 1, 1997, the Company acquired all of the outstanding
stock of ESI International, Inc., a Tennessee corporation ("ESI") and purchased
all of the members' interests in ESI North, Limited, an Ohio limited liability
company, ("ESIN" and collectively with ESI, "ESI International") for an
aggregate purchase price of $4,903,000 and $1,043,000 of assumed liabilities.
The purchase price was paid as follows: (i) $2,824,000 in cash; (ii) unsecured
promissory notes in the aggregate of $1,119,000, bearing interest at 6.5%, due
in twenty equal, consecutive, quarterly installments, with the first such
installment due on January 31, 1998; and (iii) 96,000 shares of common stock of
the Company. The number of shares of the Company's common stock issued as part
of the purchase price is subject to adjustments based on changes in the market
price of the Company's common stock during the 90-day period following the
Company's initial public offering of its common stock. The purchase price may be
increased by a maximum of $600,000 contingent upon the achievement of certain
revenue and operating objectives over the three-year period following the date
of acquisition. The acquisition has been accounted for using the purchase method
of accounting and, accordingly, the acquired assets and assumed liabilities have
been recorded at their estimated fair values as of October 1, 1997. The
accompanying unaudited consolidated financial statements include the results of
operations of ESI International from the effective acquisition date.

                                                                          Page 6

NOTE 3.  INITIAL PUBLIC OFFERING OF COMMON STOCK

         On December 1, 1997, the Registration Statement related to the
Company's initial public offering of its common stock (the "Offering") was
declared effective by the Securities and Exchange Commission and its stock began
trading on the NASDAQ national market system on December 2, 1997. Pursuant to
the terms of the Offering, on December 5, 1997, the Company issued 3,750,000
shares of common stock that were sold at $9.00 per share, the net proceeds of
which were $31,388,000 before deducting expenses of $1,138,000.

         On January 2, 1998, the over-allotment option in connection with the
Offering was partially exercised and on January 6, 1998, the Company issued an
additional 237,500 shares at $9.00 per share. The net proceeds of the partial
exercise of the over-allotment option were $1,988,000.

NOTE 4.  OFFERING RELATED TRANSACTIONS

         Restructuring of the Company and Termination of MPW's S Corporation
Status

         In connection with the Offering, effective October 30, 1997, the 
Company was restructured resulting in the creation of a new holding company,
MPW Industrial Services Group, Inc., an Ohio corporation. In connection with
this reorganization, MPW's S Corporation status was terminated. Prior to this
termination, MPW made a distribution to the S Corporation shareholders in the
amount of $21,200,000 for undistributed earnings associated with MPW's S
Corporation status. These distributions were made through the Company's
issuance of promissory notes to such shareholders (the "AAA Notes"), of which
$13,400,000 was subsequently paid off with the Offering proceeds. The remaining
$7,800,000 will be paid as follows: (i) $4,200,000 in cash on April 15, 1998
and (ii) $3,600,000 to be redeemed in connection with the sale of a corporate
aircraft to a holder of the AAA Notes.

         Deferred Stock Option Compensation Expense

         In connection with the Offering, the Company recorded a non-cash,
non-recurring charge of $1,869,000, net of tax, associated with certain of its
stock option plans. This charge resulted in a concurrent increase in paid-in
capital. The Company also eliminated the related deferred stock option 
compensation liabilities previously recorded because, effective with the
Offering, the Company's repurchase obligations for stock options exercised
under these stock option plans were eliminated.

         Related Party Lease Agreements

         In connection with the Offering, the Company restructured certain lease
agreements with its principal shareholder for facilities that the Company uses
in its business operations. Additionally, subsequent to December 31, 1997, the
Company will redeem $3,600,000 of the AAA Notes as consideration for the sale of
a corporate aircraft at its fair market value to an entity controlled by the
Company's principal shareholder. In connection with this transaction, the
Company will enter into a lease agreement with this entity for the lease of this
corporate aircraft.

         Purchase of Remaining Minority Shareholders' Interests

         In connection with the Offering, on December 5, 1997, the Company
purchased the remaining minority shareholders' interests in the equity and net
income of Aquatech for an aggregate purchase price of $678,000, at which time
Aquatech became a wholly-owned subsidiary of the Company. The purchase price was
paid as follows: (i) $339,000 in cash and (ii) 37,667 shares of common stock of
the Company.

NOTE 5.  LONG-TERM DEBT

         Prior to the Offering, the Company had various credit arrangements with
its principal banks, including term notes and a revolving credit line with
outstanding balances totaling $8,948,000 and $6,935,000, respectively, of which
$3,000,000 was associated with the Company's acquisition of ESI International.
On December 5, 1997, the entire outstanding balance under these arrangements,
$15,883,000, was repaid.

         Effective December 10, 1997, the Company entered into a new credit
agreement with its principal banks (the "Credit Facility") to replace the
existing agreement. The Credit Facility provides the Company with $50,000,000 of
unsecured credit availability for a three-year period. Under the Credit
Facility, $15,000,000 is available for working capital 

                                                                          Page 7

needs, of which $5,000,000 may be used for letters of credit, and the remaining
$35,000,000 is available for the Company's growth initiatives, including
acquisitions. Borrowing under the Credit Facility currently bears interest at
the prime rate less 0.75% or, at the Company's option, the Eurodollar market
rate plus 0.75%. The interest rate is subject to change based on interest rate
formulas tied to financial performance as measured by debt service coverage and
by the ratio of funded debt to equity. The Credit Facility also provides
covenants that impose minimum levels for interest coverage and tangible net
worth and ceiling levels for funded debt to equity. As of December 31, 1997, no
balances had been drawn on the Credit Facility. The Company pays a commitment
fee for unused portions of the Credit Facility of 0.25%.

NOTE 6.  INCOME TAXES

         Prior to October 31, 1997, MPW's income was taxed under the provisions
of Subchapter S of the Internal Revenue Code of 1986, as amended, which provides
that in lieu of corporate income taxes, the shareholders of the S Corporation
are taxed on their proportionate share of MPW's taxable income. Therefore, no
provision or liability for federal income tax has been included in historical
financial statements related to MPW prior to October 31, 1997. The accompanying
financial statements do, however, include provisions for income taxes for
federal, state, provincial and local tax purposes for the other members of the
Company that are subject to corporate income taxes.

         Effective October 30, 1997, MPW terminated its S Corporation status and
became subject to corporate income taxes. The Company recorded a current
deferred tax asset and a noncurrent deferred tax liability of $2,111,000 and
$1,409,000, respectively, to recognize the cumulative deferred income taxes
attributable to MPW's change in tax status (from an S Corporation to a C
Corporation). The Company also recorded an additional current deferred tax asset
and noncurrent deferred tax liability of $105,000 and $444,000, respectively,
related to its results of operations since October 31, 1997. Deferred income
taxes reflect the net tax effects of temporary differences between the carrying
amounts of assets and liabilities for financial reporting purposes and the
amounts used for income tax purposes. Significant components of the Company's
deferred tax asset and liability as of December 31, 1997 are related to the use
of accelerated depreciation rates on property and equipment for tax purposes and
the carryforward of tax adjustments related to the termination of MPW's S
Corporation status.

         The pro forma income taxes presented in the Consolidated Statements of
Operations for the three and six months ended December 31, 1996 and 1997
represent the estimated income taxes that would have been reported had MPW been
subject to federal and state income taxes for each of the periods presented.

NOTE 7.  EARNINGS PER SHARE

         In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128 ("SFAS No. 128"), Earnings per Share,
effective for periods ending after December 15, 1997. SFAS No. 128 replaced the
previously reported primary and fully diluted earnings per share with basic and
diluted earnings per share. Unlike primary earnings per share, basic earnings
per share excludes any dilutive effects of options, warrants and convertible
securities. Diluted earnings per share is similar to the previously reported
fully diluted earnings per share. All earnings per share amounts for all periods
have been presented to conform to the SFAS No. 128 requirements.

                                                                          Page 8

         Options to purchase 1,311,500 shares of the Company's common stock at a
weighted average price per share of $4.29 were outstanding during the three
months ended December 31, 1997, but were not included in the computation of
diluted earnings per share because the Company reported a pro forma net loss
and, therefore, the effect would be antidilutive.

         On January 2, 1998, the over-allotment option in connection with the
Offering was partially exercised and on January 6, 1998, the Company issued an
additional 237,500 shares at $9.00 per share.

NOTE 8.  1997 STOCK OPTION PLAN

         On November 15, 1997, the Company adopted a new stock option plan (the
"1997 Plan") and subsequently granted 362,500 stock options to certain
employees. The purpose of the 1997 Plan is to attract and retain directors,
officers and key employees of the Company, to enhance their interest in the
Company's continued success and to allow associates an opportunity to have an
ownership in the Company through stock options, stock awards and a stock
purchase plan. The maximum number of common shares available to be issued under
the 1997 Plan is 700,000 shares of common stock.

NOTE 9.  FLUCTUATIONS IN QUARTERLY RESULTS

         The Company's revenues and results of operations tend to vary
seasonally as a result of a number of factors over which the Company has no
control, including its customers' budgetary constraints, the timing and duration
of its customers' planned maintenance activities and shutdowns, changes in its
competitors' pricing policies and general economic conditions. Also, certain
operating and fixed costs remain relatively constant throughout the fiscal year,
which when offset by differing levels of revenues may result in fluctuations in
quarterly operating results. Because of these factors, the Company typically
generates the least amount of revenues in the third quarter, higher revenues in
the second quarter and the greatest amount of revenues in the first and fourth
quarters. Although the Company believes that the historical trend in quarterly
revenue for the first and fourth quarters are generally higher than the second
and third quarters, there can be no assurance that this will occur in future
periods. Accordingly, quarterly or other interim results should not be
considered indicative of results to be expected for any quarter or for the full
year.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF CONSOLIDATED FINANCIAL
         CONDITION AND RESULTS OF OPERATIONS.

         Except for historical information, certain statements in this
Management's Discussion and Analysis of Consolidated Financial Condition and
Results of Operations are forward looking. These forward looking statements are
based on current expectations that are subject to a number of uncertainties and
risks, and actual results may differ materially. The uncertainties and risks
include, but are not limited to, competitive and other market factors, customer
purchasing behavior, general economic conditions and other facets of the
Company's business operations as well as other risk factors identified in the
Company's Registration Statement. The Company undertakes no obligation and does
not intend to update, revise or otherwise publicly release the result of any
revisions to these forward looking statements that may be made to reflect future
events or circumstances.

         The following information should be read in conjunction with the
Unaudited Consolidated Financial Statements and Notes included in Part I, Item
1. The following information should also be read in conjunction with the Audited
Consolidated Financial Statements and Notes, and Management's Discussion and
Analysis of Financial Condition and Results of Operations for the year ended
June 30, 1997 as contained in the Company's Registration Statement.

OVERVIEW

         Effective October 1, 1997, the Company completed the acquisition of ESI
International for an aggregate purchase price of $4.9 million and $1.0 million
of assumed liabilities. The purchase price was paid with $2.8 million in cash,
96,000 shares of common stock of the Company and $1.1 million in unsecured
promissory notes which bear interest at 6.5% payable over five years.

         On December 1, 1997, the Registration Statement related to the
Company's initial public offering of its common stock was declared effective by
the Securities and Exchange Commission and its stock began trading on the NASDAQ
national market system on December 2, 1997. Pursuant to the terms of the
Offering, on December 5, 1997, the Company issued 3,750,000 shares of common
stock that were sold at $9.00 per share. On January 2, 1998, the over-allotment
option in connection with the Offering was partially exercised and on January 6,
1998, the Company issued an additional 237,500 shares at $9.00 per share. The
net proceeds to the Company in connection with the Offering, including the
partial exercise of the over-allotment option, were $33.4 million before
deducting expenses of $1.1 million.

         During the three month period ended December 31, 1997, numerous events
occurred and certain transactions were recorded that were directly related to
the Offering. These events and transactions were:

         1.   Effective October 30, 1997, MPW terminated its S Corporation
              election under subchapter S of the Internal Revenue Code of 1986,
              as amended, for federal income tax purposes and under comparable
              state tax laws. In connection therewith, MPW declared a dividend
              of $21.2 million evidenced by the AAA Notes and the Company
              recorded a net non-recurring tax benefit of $702,000 and a related
              current deferred tax asset and noncurrent deferred tax liability
              of $2.1 million and $1.4 million, respectively.

         2.   In connection with the Offering, the Company recorded a non-cash,
              non-recurring charge associated with certain of its stock option
              plans. This charge resulted in a concurrent increase in paid-in
              capital. The Company also eliminated the related deferred stock 
              option compensation liabilities previously recorded because, 
              effective with the Offering, the Company's repurchase obligations
              for stock options exercised under these stock option plans were 
              eliminated.

         3.   Effective with the Offering, the Company adjusted the historical
              lease costs for certain facilities leased by the Company from
              related parties and recharacterized such leases from capital to
              operating as a result of restructured lease agreements.

         4.   On December 5, 1997, the Company purchased certain minority stock
              ownership interests with cash in the amount of $339,000 and by the
              issuance of 37,667 shares of the Company's common stock.

         5.   On December 5, 1997 the Company used a portion of the net proceeds
              from the offering to repay $15.9 million of outstanding
              liabilities to its principal banks, including $3.0 million of
              long-term liabilities associated with the Company's acquisition of
              ESI International during the three months ended December 31, 1997.

                                                                         Page 10

<PAGE>   11

         6.   During December 1997, the Company used a portion of the net
              proceeds from the Offering to repay $13.4 million of the
              outstanding balance of the AAA Notes.

         As a result of the events discussed above and the related transactions
recorded during the three month period ended December 31, 1997, the
comparability of the results of operations for the Company for the three and six
month periods ended December 31, 1997 with the same periods in the prior year
has been affected. For purposes of this Management's Discussion and Analysis of
Consolidated Financial Condition and Results of Operations, the following
adjusted pro forma information is being presented as supplemental information to
the Consolidated Financial Statements contained in Part I, Item 1. Management's
analysis under the heading of Results of Operations below utilizes this
supplemental information.

</TABLE>


     THREE MONTHS ENDED DECEMBER 31, 1997 COMPARED TO THREE MONTHS ENDED 
     DECEMBER 31, 1996

         Basis of Presentation. Management's analysis of the three months ended
December 31, 1997 ("fiscal 1998 quarter") compared to the three months ended
December 31, 1996 ("fiscal 1997 quarter") utilizes the supplemental adjusted pro
forma information as provided in the tables on pages 11 and 12, herein.

         Revenues. Revenues increased by $6.0 million, or 33.3%, to $24.2
million for the fiscal 1998 quarter from $18.2 million for the fiscal 1997
quarter. The internal rate of growth in revenues in the fiscal 1998 quarter was
23.2% as a result of significant growth in each of the Company's principal
services lines. Revenues also increased in the fiscal 1998 quarter as a result
of the acquisition of ESI International that contributed $1.8 million of
revenues.

         Cost of Services. Cost of services increased by $4.5 million, or 37.2%,
to $16.4 million for the fiscal 1998 quarter from $11.9 million for the fiscal
1997 quarter. Cost of services as a percentage of revenues increased to 67.6%
for the fiscal 1998 quarter from 65.7% for the fiscal 1997 quarter. Projects
performed by the Company, primarily industrial cleaning projects, and work
performed for certain of the Company's industrial customers experienced lower
margins in the fiscal 1998 quarter as compared to the fiscal 1997 quarter. These
lower margin activities were partially offset by improved margins in the fiscal
1998 quarter in the Company's complementary service lines as compared to the
fiscal 1997 quarter.

         Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased by $754,000, or 21.7%, to $4.2 million for the
fiscal 1998 quarter from $3.5 million for the fiscal 1997 quarter. This increase
is primarily due to the acquisition of ESI International, infrastructure
investments to support growth in Weston since its acquisition in April 1996 and
other investments in the Company's infrastructure to support overall growth.
Selling, general and administrative expenses decreased as a percentage of
revenues to 17.5% for the fiscal 1998 quarter from 19.1% for the fiscal 1997
quarter.

         Depreciation and Amortization. Depreciation and amortization increased
by $97,000, or 12.8%, to $856,000 for the fiscal 1998 quarter from $759,000 for
the fiscal 1997 quarter. This increase is a result of additional capital
expenditures during the current fiscal year. Depreciation and amortization
decreased as a percentage of revenues to 3.5% for the fiscal 1998 quarter from
4.2% for the fiscal 1997 quarter. This decrease as a percentage of revenues is
primarily due to revenue growth in the container cleaning and industrial water
service lines for which capital investments were made in prior years and to
growth in revenues in service lines that require less capital than industrial
cleaning.

         Income from Operations. Income from operations increased $758,000, or
38.0%, to $2.8 million for the fiscal 1998 quarter from $2.0 million for the
fiscal 1997 quarter. Income from operations also increased as a percentage of

                                                                         Page 12

<PAGE>   13

revenues to 11.4% for the fiscal 1998 quarter from 11.0% for the fiscal 1997
quarter. The increase in income from operations and the improved operating
margin are due to the factors discussed above.

         Interest Expense, net. Following the Offering, the Company had no
borrowing under the Credit Facility with its banks. For this reason, interest
expense, net has been eliminated in the adjusted pro forma information to give
effect as if the repayment of the Company's debt obligations from the proceeds
of the Offering had occurred as of the beginning of each of the periods
presented. Actual interest expense before the adjusted pro forma elimination
declined to $216,000 for the fiscal 1998 quarter from $336,000 for the fiscal
1997 quarter due primarily to the repayment discussed above.

         Provision for Income Taxes. Prior to October 31, 1997, MPW was an S
Corporation for income tax purposes and did not record a provision for federal
and certain state income taxes. The provision for income taxes in the adjusted
pro forma information has been assumed to be at an effective rate of 40.0% for
each of the periods presented.

         Net Income and Net Income per Share. Net income increased $455,000, or
38.0%, to $1.7 million for the fiscal 1998 quarter from $1.2 million for the
fiscal 1997 quarter. Assuming dilution, net income per share increased to $0.15
for the fiscal 1998 quarter from $0.11 for the fiscal 1997 quarter. These
increases are due to the factors discussed above. Weighted average common shares
outstanding used in the calculation of net income per share assumes that the
Offering and repurchase of minority interests had occurred at the beginning of
each of the periods presented.

     SIX MONTHS ENDED DECEMBER 31, 1997 COMPARED TO SIX MONTHS ENDED 
     DECEMBER 31, 1996

         Basis of Presentation. Management's analysis of the six months ended
December 31, 1997 ("six month fiscal 1998 period") compared to the six months
ended December 31, 1996 ("six month fiscal 1997 period") utilizes the
supplemental adjusted pro forma information as provided in the tables on pages
11 and 12, herein.

         Revenues. Revenues increased by $8.5 million, or 22.6%, to $46.1
million for the six month fiscal 1998 period from $37.6 million for the six
month fiscal 1997 period. The internal rate of growth in revenues in the six
month fiscal 1998 period was 17.7% as a result of growth of more than 11.0% in
industrial cleaning and facility support along with significant growth in each
of the Company's complementary services lines. Revenues also increased in the
six month fiscal 1998 period as a result of the acquisition of ESI International
that contributed $1.8 million of revenues.

         Cost of Services. Cost of services increased by $6.1 million, or 25.1%,
to $30.7 million for the six month fiscal 1998 period from $24.6 million for the
six month fiscal 1997 period. Cost of services as a percentage of revenues
increased to 66.7% for the six month fiscal 1998 period from 65.5% for the six
month fiscal 1997 period. Projects and work performed by the Company for certain
of the Company's industrial customers experienced lower margins in the six month
fiscal 1998 period as compared to the six month fiscal 1997 period. Improved
margins in the Company's complementary service lines in the six month fiscal
1998 period as compared to six month fiscal 1997 period partially offset the
lower margins discussed above.

         Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased by $959,000, or 14.0%, to $7.8 million for the
six month fiscal 1998 period from $6.9 million for the six month fiscal 1997
period. This increase is primarily due to the acquisition of ESI International
and investments in the Company's infrastructure to support its overall growth.
Selling, general and administrative expenses decreased as a percentage of
revenues to 17.0% for the six month fiscal 1998 period from 18.2% for the six
month fiscal 1997 period.

         Depreciation and Amortization. Depreciation and amortization increased
by $220,000, or 14.9%, to $1.7 million for the six month fiscal 1998 period from
$1.5 million for the six month fiscal 1997 period. This increase is primarily a
result of additional capital expenditures during the current fiscal year.
Depreciation and amortization decreased as a percentage of revenues to 3.7% for
the six month fiscal 1998 period from 3.9% for the six month fiscal 1997 period.
This decrease as a percentage of revenues is primarily due to revenue growth in
service lines for which less capital is required.

         Income from Operations. Income from operations increased $1.1 million,
or 24.2%, to $5.8 million for the six month fiscal 1998 period from $4.7 million
for the six month fiscal 1997 period. Income from operations also increased as a
percentage of revenues to 12.6% for the six month fiscal 1998 period from 12.4%
for the six month fiscal 1997 period. The increase in income from operations and
the improved operating margin are due to the factors discussed above.

                                                                         Page 13

<PAGE>   14

         Interest Expense, net. Following the Offering, the Company had no
borrowing under the Credit Facility with its banks. For this reason, interest
expense, net has been eliminated in the adjusted pro forma information to give
effect as if the repayment of the Company's debt obligations from the proceeds
of the Offering had occurred as of the beginning of each of the periods
presented. Actual interest expense before the adjusted pro forma elimination was
$551,000 for the six month fiscal 1998 period compared to $550,000 for the six
month fiscal 1997 period.

         Provision for Income Taxes. Prior to October 31, 1997, MPW was an S
Corporation for income tax purposes and did not record a provision for federal
and certain state income taxes. The provision for income taxes in the adjusted
pro forma information has been assumed to be at an effective rate of 40.0% for
each of the periods presented.

         Net Income and Net Income per Share. Net income increased $680,000, or
24.2%, to $3.5 million for the six month fiscal 1998 period from $2.8 million
for the six month fiscal 1997 period. Assuming dilution, net income per share
increased to $0.33 for the six month fiscal 1998 period from $0.26 for the six
month fiscal 1997 period. These increases are due to the factors discussed
above. Weighted average common shares outstanding used in the calculation of net
income per share assumes that the Offering and repurchase of minority interests
had occurred at the beginning of each of the periods presented.


QUARTERLY RESULTS AND SEASONALITY

         The Company's results of operations tend to vary seasonally, with the
least amount of revenues generated in the third quarter, higher revenues in the
second quarter and the greatest amount of revenues in the first and fourth
quarters. The Company's quarterly results of operations may fluctuate
significantly as a result of a number of factors over which the Company has no
control, including its customers' budgetary constraints, the timing and duration
of its customers' planned maintenance activities and shutdowns, changes in its
competitors pricing policies and general economic conditions. Also, certain
operating and fixed costs remain relatively constant throughout the fiscal year
that, when offset by differing levels of revenues, may result in fluctuations in
quarterly results.


LIQUIDITY AND CAPITAL RESOURCES

         The proceeds of the Offering received by the Company on December 5,
1997 were $30.3 million, net of underwriting discounts and other costs
associated with the Offering of $3.5 million. Of the proceeds, the Company used
$15.9 million to repay all of the outstanding debt under the Company's various
credit arrangements with its principal banks. The amount repaid included $3.0
million relating to the acquisition of ESI International that occurred during
the fiscal 1998 quarter. Additionally, $13.4 million was used to satisfy a
portion of the AAA Notes. As a result of these payments, and as of December 31,
1997, the Company had no borrowing from its principal banks.

         On January 6, 1998, the Company received an additional $2.0 million,
net of underwriting discounts of $150,000 from the exercise of a portion of the
underwriters' over-allotment option for 237,500 shares.

         The Company's total debt as of December 31, 1997, including current
maturities, was $9.7 million. Of this amount, $4.2 million is the amount of AAA
Notes due April 15, 1998, which the Company intends to satisfy primarily with
its cash on hand, including the proceeds from the partial exercise of the
over-allotment option. The remaining amount of AAA Notes is $3.6 million that 
will be redeemed by an entity controlled by the Company's principal shareholder
for the sale of a certain aircraft. The remaining amount of the Company's debt
of $1.9 million is related to the acquisition of ESI International.

         As of December 31, 1997, the Company had cash and cash equivalents of
$788,000 and working capital of $6.3 million. During the six month fiscal 1998
period, the Company had net cash provided by operating activities of $2.9
million, made capital investments of $2.5 million and made cash payments for the
acquisition of ESI International of $2.7 million, net of cash received.

         Effective December 10, 1997, the Company entered into the Credit
Facility with its principal banks. This Credit Facility provides the Company
with $50.0 million of credit availability for a three-year period. Under the
Credit Facility, $15.0 million is to be used for working capital needs, of which
$5.0 million may be used for letters of credit. The remaining $35.0 million is
available for use by the Company in growth initiatives such as capital
expenditure programs and 

                                                                         Page 14

acquisitions. Borrowing under the Credit Facility is at rates, based on the
prime rate or LIBOR, that the Company believes to be very favorable.
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 certain ratio of funded debt to equity that the Company believes are very
achievable. As of December 31, 1997, no amounts had been drawn on the Credit
Facility.

         The Company believes that cash on hand as of December 31, 1997, cash
received from the partial exercise of the over-allotment option, cash flow from
operations and available borrowing under the Credit Facility will be sufficient
to fund its currently planned capital projects and operations for at least the
next 24 months. The Company actively seeks opportunities to expand its business
operations. If acquisition opportunities develop, the Company believes that it
has adequate financing capacity in the Credit Facility. If acquisition
opportunities of significant size develop that would extend the Company's
borrowing beyond the capacity of the Credit Facility, the Company may be
required to seek additional financing.


INFLATION

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

                  (c)      On October 30, 1997, each of the shareholders of MPW,
                           Monte R. Black, Susan K. Black and the Monte R. Black
                           and Susan K. Black 1994 Irrevocable Trust contributed
                           to the Company their shares of MPW for shares in the
                           Company on a one to one basis. The shareholders of
                           MPW received an aggregate of 1,550,000 shares of
                           common stock of the Company (subsequently subject to
                           a four to one stock split) reflecting their ownership
                           interests in the Company. The sale of the Company's
                           common stock to the shareholders of MPW was pursuant
                           to Section 4(2) of the Securities Act of 1933, as
                           amended (the "Act").

                           On October 31, 1997, pursuant to a Merger and
                           Purchase Agreement dated as of October 1, 1997 (the
                           "Agreement") among ESI and ESIN, the owners of ESI
                           and ESIN, the Company and MPW Filtration Acquisition
                           Corp. ("Filtration"), ESI merged with and into
                           Filtration (the "Merger"), and the Company and
                           Filtration purchased membership interests of ESIN. As
                           partial consideration for the Merger, the Company
                           issued 96,000 shares of its common stock to certain
                           of the owners of ESI as follows: 40,000 shares to Mr.
                           Barry Thiel, 24,100 shares to Mr. Jerry Broyles,
                           11,900 shares to Mr. Dan Jones and 10,000 shares to
                           each of Mr. George Sullivan and Mr. Kelly Six. Each
                           of the owners were officers and directors of ESI and
                           have entered into employment and non-competition
                           agreements with the Company and the surviving
                           corporation in the Merger. The number of shares of
                           the Company's common stock issued to such owners is
                           subject to adjustment upon completion of the Offering

                           common stock to the public at a price of $9.00 per
                           share. The Company received net proceeds from the
                           Offering of $32,238,000 after deducting expenses of

                           (i) repaid all of the outstanding debt of $15,883,000
                           under the Company's various credit arrangements with

                           Aquatech. The payments used to partially repay the 
                           AAA Notes were made to Monte R. Black, the Company's

for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the Banks, the Agent and the Borrowers do hereby agree
as follows:

Agreement, as the same may be amended, modified, supplemented, extended,
restated or replaced from time to time.

                  "AUTHORIZED OFFICER" shall mean the chief executive officer,
the chief financial officer or the treasurer of a Borrower, as the case may be.

           AMOUNT AND TERMS OF COMMITMENTS, REVOLVING CREDIT LOANS AND
           -----------------------------------------------------------
                                   TERM LOANS
                                   ----------

         SECTION 2.1 COMMITMENTS.

                  (a) Subject to the terms and conditions of this Agreement,
each Bank severally agrees to make Revolving Credit Loans to the Borrowers from
time to time during the Commitment Period; provided that, immediately after each
such Revolving Credit Loan is made, the aggregate principal amount of Revolving
Credit Loans by such Bank shall not exceed the amount of its Revolving Loan
Commitment (as such Revolving Loan Commitment may be increased or reduced from
time to time in accordance with the terms of this Agreement), either as to
Dollar amount or its Revolving Credit Loan Commitment Percentage. Each borrowing
for a Revolving Credit Loan shall be in an aggregate principal amount of at
least $100,000, or larger multiples of $10,000, and shall be made by the Banks
in accordance with each Bank's respective Revolving Credit Loan Commitment
Percentage. During the Commitment Period and as long as no Default or Event of
Default exists, the Borrowers may use the Revolving Loan Commitment by

                                      -17-

<PAGE>   23



borrowing, repaying the Revolving Credit Loans, in whole or in part, and
reborrowing, all in accordance with the terms and conditions hereof.

                  (b) Subject to the terms and conditions of this Agreement, up
to $5 million of the Revolving Loan Commitment may be taken, from time to time,
at the Borrowers' option, in the form of Standby L/Cs pursuant to the terms
hereof and the Standby L/C Applications. Amounts paid against draws under
Standby L/Cs shall be considered to be Revolving Credit Loans outstanding under
the Revolving Loan Commitment until such amounts shall have been reimbursed to
the Bank pursuant to the terms of the Standby L/C Applications.

                  (c) Subject to the terms and conditions of this Agreement,
each Bank severally agrees to make Term Loans to the Borrowers from time to time
during the Commitment Period; provided that, immediately after each such Term
Loan is made, the aggregate principal amount of Term Loans by such Bank shall
not exceed the amount of its Term Loan Commitment (as such Term Loan Commitment
may be increased or reduced from time to time in accordance with the terms of
this Agreement), either as to Dollar amount or its Term Loan Commitment
Percentage. Each borrowing for a Term Loan shall be in an aggregate principal
amount of at least $1 million, and shall be made from the several Banks in
accordance with each Bank's respective Term Loan Commitment Percentage. After
the funding of any Term Loan, the Borrowers shall not have the ability to
reborrow, in whole or in part, any amounts repaid with respect to the Term
Loans.

                  (d) Within the limits of the Commitments and subject to the
other terms and conditions of this Agreement and the other Facility Documents,
each Borrower may borrow hereunder and, with respect to Revolving Credit Loan
Commitment, repay and reborrow.

                  (e) Notwithstanding any provision hereof to the contrary, the
total amount of the sum of (i) the amount of outstanding and unpaid Revolving
Credit Loans, PLUS (ii) the amount of Term Loans funded hereunder, PLUS (iii)
the total aggregate Dollar amount available to be drawn under outstanding
Standby L/Cs, shall at no time exceed the Aggregate Commitment.

         SECTION 2.2 NOTES.

                  (a) The Revolving Credit Loans made by each Bank to the
Borrowers pursuant hereto shall be evidenced by a separate Revolving Credit Loan
Note payable to the order of such Bank in an aggregate amount equal to the
Revolving Credit Loan Commitment of such Bank at any time. Each Revolving Credit
Loan Note shall (i) be dated as of the date the Revolving Credit Loan Note is
issued or reissued, as the case may be, (ii) be in a principal amount
corresponding to the aggregate amount of such Bank's Revolving Credit Loan
Commitment when so issued or reissued, as the case may be, (iii)

                                      -18-

<PAGE>   24



bear interest as determined pursuant to this Agreement, (iv) mature on the
Termination Date, and (v) require accrued interest to be paid on the applicable
Interest Payment Date and at maturity in accordance with the terms of this
Agreement.

                  (b) Each Term Loan made by each Bank to the Borrowers pursuant
hereto shall be evidenced by a separate Term Loan Note payable to the order of
such Bank in an aggregate amount equal to the Term Loan Commitment Percentage of
such Bank multiplied by the amount of Term Loan. Each Term Loan Note shall (i)
be dated as of the date the Term Loan Note is issued or reissued, as the case
may be, (ii) be in a principal amount equal to the Term Loan Commitment
Percentage of such Bank multiplied by the amount of Term Loan when so issued or
reissued, as the case may be, (iii) require principal to be repaid in 20 equal
consecutive payments of principal to be paid on the last day of each Fiscal
Quarter, (iv) bear interest as determined pursuant to this Agreement, (v) mature
on the applicable Term Loan Maturity Date, and (vi) require accrued interest to
be paid on the applicable Interest Payment Date and at maturity in accordance
with the terms of this Agreement.

                  (c) Upon receipt of each Bank's Note pursuant to Article IV,
the Agent shall forward such Note to such Bank. Each Bank is hereby authorized
to record electronically or otherwise the date and amount of each Loan
disbursement made by such Bank, the date and amount of each payment or repayment
of principal thereof, the type of such borrowing (whether a Eurodollar Rate Loan
or a Base Rate Loan), and such other information as it deems necessary or
appropriate. Such recordation shall constitute prima facie evidence of the
accuracy of the information so recorded; provided, however, the failure of such
Bank to make any such recordation(s) shall not affect the obligation of the
Borrowers to repay outstanding principal, interest or any other amount due
hereunder or under such Note in accordance with the terms hereof and thereof.

         SECTION 2.3 NOTICE OF LOAN BORROWING; FUNDING OF LOANS.

                  (a) When the Borrowers desire to borrow hereunder with respect
to a Revolving Credit Loan, the Borrowers shall give the Agent notice (a "Notice
of Revolving Credit Loan Borrowing"). Such Notice of Revolving Credit Loan
Borrowing (i) shall be irrevocable, and (ii) must be received by the Agent prior
to (x) 10:30 a.m. Columbus, Ohio time, at least one (1) Business Day prior to
the proposed date of the borrowing, which date shall be a Business Day (a
"Revolving Credit Loan Borrowing Date"), if all or any part of the requested
Revolving Credit Loans are to be initially Eurodollar Rate Loans, or (y) 10:30
a.m. Columbus, Ohio time, at least one (1) Business Day prior to the Revolving
Credit Loan Borrowing Date if all of the requested Revolving Credit Loans are to
be initially Base Rate Loans. Each such Notice of Revolving Credit Loan
Borrowing shall specify (i) the amount to be borrowed, (ii) the requested
Revolving Credit Loan Borrowing Date, (iii) whether the borrowing is to be of
Eurodollar Rate Loans, Base Rate Loans or a

                                      -19-

<PAGE>   25



combination thereof, and (iv) if the borrowing is to be entirely or partly of
Eurodollar Rate Loans, the amount and the Interest Period with respect to each
Eurodollar Rate Loan.

                  (b) When the Borrowers desire to borrow hereunder with respect
to a Term Loan, the Borrowers shall give the Agent notice (a "Notice of Term
Loan Borrowing"). Such Notice of Term Loan Borrowing must be received by the
Agent at least five (5) days prior to the proposed date of the borrowing, which
date shall be a Business Day (a "Term Loan Borrowing Date"). Each such Notice of
Term Loan Borrowing shall specify (i) the amount to be borrowed, (ii) the
requested Term Loan Borrowing Date, (iii) whether the borrowing is to be of
Eurodollar Rate Loans, Base Rate Loans or a combination thereof, and (iv) if the
borrowing is to be entirely or partly of Eurodollar Rate Loans, the amount and
the Interest Period with respect to each Eurodollar Rate Loan. In addition, if
the requested Term Loan is in connection with an acquisition pursuant to Section
2.11(y), the information required to be provided to the Banks pursuant to such
Section 2.11(y) shall have been provided to the Banks and any necessary consents
required by such Section 2.11(y) shall have given by the Banks prior to the date
the relevant Notice of Term Loan Borrowing is given to the Agent.

                  (c) Upon receipt of a Notice of Borrowing given in accordance
with subsections (a) or (b) above, the Agent shall promptly notify each Bank of
the contents thereof and of such Bank's Revolving Credit Loan in proportion to
its Revolving Credit Loan Commitment Percentage or such Bank's Term Loan in
proportion to its Term Loan Commitment Percentage, as the case may be.

                  (d) Unless the Agent determines that any applicable
condition(s) specified in Article IV has not been satisfied not later than 12:00
noon, Columbus, Ohio time on the applicable Loan Borrowing Date, each Bank shall
make available its Loan in proportion to its Loan Commitment Percentage in
federal or other funds immediately available in Columbus, Ohio, to the Agent at
its address set forth in Section 11.4, and in turn, the Agent will promptly make
the funds so received from the Banks available to the Borrowers at the Agent's
aforesaid address.

                  (e) In the event that a Notice of Borrowing fails to specify
whether the Loans are to be Eurodollar Rate Loans or Base Rate Loans, or a
combination thereof, such Loans shall be made as Base Rate Loans.

                  (f) There may be no more than four (4) different Interest
Periods for Eurodollar Rate Loans outstanding at the same time (for which
purpose Interest Periods described in the definition of the term "Interest
Period" shall be deemed to be different Interest Periods even if they are
coterminous).

                  (g) Unless the Agent shall have received notice from a Bank
prior to a Loan Borrowing Date that such Bank will not make available to the
Agent the amount that

                                      -20-

<PAGE>   26



would constitute its Loan Commitment Percentage of the borrowing to be made on
such date, the Agent may assume that such Bank has made such amount available to
the Agent on such Loan Borrowing Date, and the Agent may, in reliance upon such
assumption, make available to the Borrowers a corresponding amount. If and to
the extent that such Bank shall not have so made such amount available to the
Agent, such Bank and the Borrowers shall severally repay to the Agent on demand
such corresponding amount, together with interest thereon for each day from the
date such amount is made available to the Borrowers until the date such amount
is repaid to the Agent, at (i) in the case of the Borrowers, a rate per annum
equal to the interest rate applicable thereto pursuant to Section 2.7, and (ii)
in the case of such Bank, the Federal Funds Rate. If such Bank shall repay to
the Agent such corresponding amount, such amount so repaid shall constitute such
Bank's Revolving Credit Loan included in such borrowing for purposes of this
Agreement. Nothing in this subsection (g) shall be interpreted to relieve any
Bank of its obligations to make Loans hereunder.

                  (h) The failure of any Bank to make the Loan to be made by it
on any Loan Borrowing Date shall not relieve any other Bank of its respective
obligation, if any, hereunder to make its Loan on such Loan Borrowing Date, but
no Bank shall be responsible for the failure of any other Bank to make the Loan
to be made by such other Bank on such Loan Borrowing Date.

         SECTION 2.4 CONVERSION AND CONTINUATION OPTIONS.

                  (a) All Loans shall bear interest at the initial Interest Rate
selected by the Borrowers for such Loan until (i) the Interest Rate is converted
to another Interest Rate in accordance with the terms of this Agreement, or (ii)
the Borrowers convert such Interest Rate(s) to a different Interest Rate in
accordance with the terms of this Agreement.

                  (b) The Borrowers may elect from time to time to convert
outstanding Loans from one Interest Rate to the other Interest Rate by giving
prior irrevocable notice (a "Notice of Interest Rate Conversion") to the Agent
prior to the requested conversion date, which date shall be a Business Day (a
"Interest Rate Conversion Date") as follows:

                           (i) The Borrowers may elect from time to time to
         convert outstanding Loans from Eurodollar Rate Loans to Base Rate Loans
         by giving prior irrevocable notice (a "Notice of Interest Rate
         Conversion") to the Agent at least one (1) Business Day prior to the
         requested Interest Rate Conversion Date of such election; provided,
         however, that any such conversion of Eurodollar Rate Loans may only be
         made on the last day of an Interest Period with respect thereto. Each
         such Notice of Interest Rate Conversion shall specify (i) the Loans to
         be so converted, and (ii) the requested Interest Rate Conversion Date.


                                      -21-

<PAGE>   27



                           (ii) The Borrowers may elect from time to time to
         convert outstanding Loans from Base Rate Loans to Eurodollar Rate Loans
         by giving the Agent a Notice of Interest Rate Conversion at least one
         (1) Business Day prior to the requested Interest Rate Conversion Date.
         Each such Notice of Interest Rate Conversion shall specify (i) the
         Loans to be so converted, (ii) the requested Interest Rate Conversion
         Date, and (iii) the respective amounts of each Eurodollar Rate Loan and
         the Interest Period with respect thereto.

                  (c) All or any part of outstanding Eurodollar Rate Loans and
Base Rate Loans may be converted as provided herein, provided that (x) no Loan
may be converted into a Eurodollar Rate Loan when any Default or Event of
Default has occurred and is continuing hereunder, (y) no Loan may be converted
into, or continued as, a Eurodollar Rate Loan after the date that is one month
prior to the Termination Date, and (z) such conversion otherwise complies with
the applicable provisions of the proposed Interest Period and this Agreement.

                  (d) The Borrowers may elect from time to time to continue any
Eurodollar Rate Loan as such upon the expiration of the then current Interest
Period with respect thereto by giving prior notice of such continuation to the
Agent at least three (3) Business Days prior to the requested continuation date;
provided that no Eurodollar Rate Loan may be continued as such (x) when any
Default or Event of Default has occurred and is continuing, (y) after the date
that is one month prior to the Termination Date, and (z) such continuation
otherwise complies with the applicable provisions of the proposed Interest
Period and this Agreement. If the Borrowers shall fail to give any required
notice as described above in this subsection or if such continuation is not
permitted pursuant to the terms of this Agreement, such Loan shall be
automatically converted to a Base Rate Loan on the last day of such then
expiring Interest Period.

         SECTION 2.5 OPTIONAL TERMINATION OR REDUCTION OF COMMITMENTS. During
the Commitment Period and provided no Default or Event of Default shall then
have occurred and be continuing, the Borrowers may, upon at least thirty (30)
days' prior written notice to the Agent and the Banks:

                  (a) permanently terminate the Revolving Credit Loan
Commitments at any time, if no Revolving Credit Loans and/or Standby L/Cs are
outstanding at such time;

                  (b) permanently and ratably (as among the Banks) reduce from
time to time, by an aggregate amount of $500,000 or any larger multiple of
$100,000, the aggregate amount of the Revolving Credit Loan Commitments in
excess of the then aggregate outstanding principal amount of the Revolving
Credit Loans;

                  (c) permanently terminate the Term Loan Commitments at any
time, if no Term Loans are outstanding at such time;

                                      -22-

<PAGE>   28



                  (d) permanently and ratably (as among the Banks) reduce from
time to time by an aggregate amount of $500,000 or any larger multiple of
$100,000 the aggregate amount of the Term Loan Commitments in excess of the
aggregate principal amount of Term Loans previously funded.

         SECTION 2.6 TERMINATION OF COMMITMENTS.

                  (a) The Revolving Credit Loan Commitments shall terminate on
the Termination Date and any Revolving Credit Loans then outstanding, together
with all accrued interest thereon and all other outstanding fees, charges and
expenses payable hereunder and under the other Facility Documents shall be due
and payable immediately.

                  (b) The Term Loan Commitments shall terminate on the
Termination Date.

                  (b) The Applicable Margin shall be determined as of the first
day of each Fiscal Quarter (each a "Rate Determination Date") based upon the
calculation of the Leverage Ratio and Coverage Ratio of the Borrowers as of the
end of the second Fiscal Quarter next preceding a Rate Determination Date as set
forth in the certificate of the Authorized Officer required to be delivered to
the Bank pursuant to Section 6.2(a). Such Applicable Margin shall remain in
effect from such Rate Determination Date until the next Rate Determination Date,
provided that:

                           (i) in the case of an Applicable Margin determined
         from such certificate of the Authorized Officer for the fourth and
         final Fiscal Quarter of every Fiscal Year, in the event that the annual
         financial statements for such Fiscal Year subsequently provided to the
         Bank indicate that the Applicable Margin originally determined to be
         effective on the Rate Determination Date immediately following the end
         of such Fiscal Quarter was inappropriate in light of such annual
         financial statements, then the Applicable Margin shall be adjusted
         retroactively to such Rate Determination Date to reflect the proper
         Applicable Margin; and

                           (ii) if on any Rate Determination Date the Borrowers
         shall have failed to have delivered to the Bank such certificate of the
         Authorized Officer required be delivered pursuant to Section 6.2(a)
         with respect to the second preceding Fiscal Quarter, then for the
         period beginning on such Rate Determination Date and ending on the
         earlier of (x) the date on which the Borrowers shall deliver to the
         Bank the delinquent certificate or (y) the date on which the Borrowers
         shall deliver to the Bank such certificate of the Authorized Officer
         required to be delivered pursuant to Section 6.2(a) with respect to the
         Fiscal Year which includes such Fiscal Quarter, the Applicable Margin
         shall be determined as if the Leverage Ratio and Coverage Ratio of the
         Borrowers were (x) equal to or greater than 1.0 to 1.0 and (y) greater
         than 1.5 to 1.0, respectively, at all times during such period. Any
         change in the Applicable Margin on any Rate Determination Date shall
         immediately result in a corresponding change to the Interest Rate
         applicable to each Revolving Credit Loan or Term Loan outstanding on
         such Rate Determination Date.

                  (c) Each Base Rate Loan shall bear interest on the outstanding
principal amount thereof, for each day from the date such Base Rate Loan is made
and continuing while outstanding and unpaid, at a rate equal to the sum of (i)
the Base Rate, PLUS (ii) the

                                      -24-

<PAGE>   30



Applicable Margin. Accrued interest shall be payable on each applicable Interest
Payment Date. The Base Rate shall be adjusted automatically and as of the
effective date of any change in the Base Rate. Interest on Base Rate Loans shall
be calculated on the basis of a year of 365/366 days for the actual number of
days elapsed. Any overdue principal of, and to the extent permitted by
applicable law, overdue interest on, any Base Rate Loan shall bear interest,
payable on demand, for each day until paid at a rate equal to the Default Rate
for such day.

                  (d) Each Eurodollar Rate Loan shall bear interest on the
outstanding principal amount thereof, for each day from the date such Eurodollar
Rate Loan is made and continuing while outstanding and unpaid, at a rate equal
to the sum of (i) the Eurodollar Rate, PLUS (ii) the Applicable Margin. Such
interest shall be payable on each applicable Interest Payment Date. Interest on
Eurodollar Rate Loans shall be calculated on the basis of a year of 360 days and
30 day months. The Eurodollar Rate shall be adjusted automatically and as of the
effective date of any change in any Eurodollar Reserve Requirement, as
applicable. Any overdue principal of, and to the extent permitted by law,
overdue interest on, any Eurodollar Rate Loans shall bear interest, payable on
demand, for each day until paid at the rate or equal to the Default Rate for
such day.

                  (e) The Agent shall determine each Interest Rate applicable to
the Loans hereunder and its determination shall be conclusive in the absence of
manifest error.

         SECTION 2.8 FEES.

                  (a) The Borrowers, upon execution of this Agreement, shall pay
to the Agent, for the ratable benefit of the Banks, a facility fee of $62,500.

                  (b) During the Commitment Period, the Borrowers shall pay to
the Bank a commitment fee at a rate of 1/4% per annum of the daily average
Available Commitment (calculated on the basis of a 365/366-day year for the
actual number of days elapsed); provided, that the aggregate Dollar amount
available to be drawn under outstanding Standy L/Cs shall be included as usage
in determining this commitment fee. Such commitment fee shall accrue on the
Available Commitment beginning on the date hereof and shall continue to accrue
thereafter through the Termination Date. The accrued commitment fee shall be
payable (i) quarterly in arrears on the last day of each Fiscal Quarter
(beginning with the Fiscal Quarter ending on December 31, 1997, and (ii) on the
Termination Date.

         SECTION 2.9 PREPAYMENTS.

                  (a) OPTIONAL PREPAYMENTS. Subject in the case of any
Eurodollar Rate Loan to Section 2.13, the Borrowers may, at their option and
upon at least one (1) Business Day's notice to the Agent, prepay any Base Rate

(3) Business Days' notice to the Agent, prepay any Term Loans, in each case in
whole at any time, or in part from time to time in amounts aggregating at least
$100,000, by paying the principal amount to be prepaid together with accrued
interest thereon to the date of prepayment. In its notice of prepayment, the
Borrowers shall specify the date of prepayment and the amount of the prepayment.
Each such optional prepayment shall be applied to prepay ratably the Term Loans
of the Banks. Upon receipt of notice of a prepayment pursuant to this
subsection, the Agent shall promptly notify each Bank of the contents thereof
and of such Bank's ratable share of such prepayment and such notice shall not
thereafter be revocable by the Borrowers. All prepayments shall be applied to
installments of principal of the Term Loan in the inverse order of their

                  (b) MANDATORY PREPAYMENT. Upon notice to the Borrowers by the
Agent, the Borrowers shall prepay the Loans (together with any funding losses
and expenses and premiums required to be paid pursuant Section 2.13) or provide
cash to the Bank with respect to outstanding and undrawn Standby L/Cs on each
such date as and to the extent the outstanding balance of all Loans PLUS the
Dollar amount available to be drawn under outstanding Standby L/Cs exceeds the
Aggregate Commitment. Each such mandatory prepayment shall be applied to prepay
ratably the Loans of the Banks. Upon receipt of any prepayment pursuant to this
subsection, the Agent shall promptly notify each Bank of such Bank's ratable
share of such prepayment or cash held to fully collateralize such outstanding
Standby L/Cs.

         SECTION 2.10 GENERAL PROVISIONS AS TO THE LOANS AND PAYMENTS AND
FUNDING OF LOANS.

                  (a) The Borrowers shall make each payment of principal of, and
interest on, the Loans and of each Bank's fees hereunder not later than 11:00
a.m. (Columbus, Ohio time) on the date when due, in federal or other funds
immediately available at the place where payment is due, to the Agent at the
Agent's address set forth in Section 11.4. The Agent shall distribute such
payments ratably to the Banks promptly upon receipt in like funds as received.

                  (b) Whenever any payment of principal of, or interest on, any
Loan or of such fees shall be due on a day which is not a Business Day, the day
for payment thereof shall be extended to the next succeeding Business Day. If
the date for any payment of principal is so extended or is extended by operation
of law or otherwise, interest thereon shall be payable for such extended time
period.

                  (c) For the purpose of computing the Available Commitment, the
Agent and the Banks shall have the right, in their sole discretion, to treat as
outstanding Loans under this Agreement the unpaid amount of any interest, fees,
costs or expenses otherwise then due and payable hereunder and under the Notes
and the other Facility Documents;

                                      -26-

<PAGE>   32



provided, however, that such interest, fees, costs or expenses shall not be
deemed to be outstanding Loans for purposes of Section 2.8(b).

                  (c) Upon receipt of each Bank's Note pursuant to Article IV,
the Agent shall forward such Note to such Bank.

         SECTION 2.11 USE OF PROCEEDS. The Borrowers represent and agree that
(i) the proceeds of the Revolving Credit Loans made hereunder shall be used by
the Borrowers only for repayment of Debt and working capital and general
corporate purposes and with respect to Standby L/Cs, and (ii) the proceeds of
the Terms Loans made hereunder shall be used by the Borrowers only to fund (x)
capital expenditures permitted by this Agreement, and (y) acquisitions which
meet the following requirements:

                  (A) the Banks shall have been provided any information
         requested in accordance with Section 6.2(c); and

                  (B) if the cost of the proposed acquisition would be in excess
         of 25% of the Borrowers' Consolidated Tangible Net Worth at such time,
         the prior consent of the Banks is obtained.

         SECTION 2.12 LOAN ADMINISTRATION. The Banks shall have no obligation to
(i) advance or re-advance any sums or make any Loan, or (ii) issue any Standby
L/C, pursuant to terms of this Agreement at any time when a Default or an Event
of Default exists.

         SECTION 2.13 FUNDING LOSSES. If the Borrowers make any payment of
principal with respect to any Eurodollar Rate Loan (including as a mandatory
prepayment pursuant to Section 2.9(b)) or any Eurodollar Rate Loan is converted
to a Base Rate Loan pursuant to this Agreement on any day other than the last
day of any Interest Period applicable thereto, or if the Borrowers fail to
borrow, prepay, convert or continue any Eurodollar Rate Loan after notice has
been given to the Agent in accordance with this Agreement, the Borrowers shall
reimburse each Bank within 15 days after demand for any resulting loss or
expense incurred by it (or by an existing or prospective Participant in the
related Loan), including, without limitation, any loss incurred in obtaining,
liquidating or employing deposits from third parties, but excluding loss of
margin for the period after any such payment or conversion, provided that such
Bank shall have delivered to the Borrowers a certificate as to the amount of
such loss or expense, which certificate shall be conclusive in the absence of
manifest error.

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

         SECTION 3.1 ISSUANCE OF STANDBY L/CS.

                  (a) REQUEST TO ISSUE. The Borrowers may request Bank One to
issue, extend or modify a Standby L/C by delivery to Bank One of a Standby L/C
Application completed to the satisfaction of Bank One, together with the
proposed form of such Standby L/C and such other certificates, documents and
other papers and information as Bank One may reasonably request.

                  (b) FORM AND EXPIRY. Each Standby L/C issued hereunder shall,
among other things, (i) be in such form requested by the Borrowers and shall be
acceptable to Bank One in its sole discretion, and (ii) have an expiry date
occurring (x) not later than one year after such Standby L/C's date of issuance,
and (y) not later than the Termination Date. If the Commitment is terminated,
not later than such termination, all outstanding Standby L/Cs shall be returned
to Bank One or the Borrowers shall provide cash to the Agent, for the ratable
benefit of the Banks, to fully collateralize all outstanding Standby L/Cs. Each
Standby L/C Application and each Standby L/C shall be subject to the Uniform
Customs and, to the extent not subject to the Uniform Customs and, to the extent
not inconsistent therewith, the laws of the State of Ohio.

                  (c) PROCEDURE FOR OPENING STANDBY L/CS. Upon receipt of any
Standby L/C Application and the requested form of the Standby L/C from the
Borrowers, Bank One will review such Standby L/C Application and the other
certificates, documents, information and papers delivered to Bank One in
connection therewith, in accordance with its customary procedures and shall
promptly notify the Borrowers of its decision whether to issue the Standby L/C
and, if its decision is to issue the Standby L/C on the terms and in the form
requested, open such Standby L/C by issuing the original of such Standby L/C to
the beneficiary thereof and by furnishing a copy thereof to the Borrowers.

                  (d) PAYMENTS. The Borrowers agree (i) to reimburse Bank One
forthwith upon its demand and otherwise in accordance with the terms of the
Standby L/C Application relating thereto, for any expenditure or payment made by
Bank One under or in connection with any Standby L/C and (ii) to pay interest on
any unreimbursed portion of any such payment from the due date of any such
payment until reimbursement in full thereof at a rate per annum equal to (x)
prior to the date which is one Business Day after the date on which Bank One
demands reimbursement from the Borrowers for such payment, the rate which would
then be payable on any outstanding Revolving Credit Loan when no Event of
Default is existing, and (y) thereafter, the rate which would then be payable on
any outstanding Revolving Credit Loan during the existence of an Event of
Default.

                  (e) STANDBY L/C FEES. In lieu of any letter of credit
commissions and fees provided for in any Standby L/C Application (other than
standard issuance, amendment and negotiation fees), the Borrowers agree to pay
Bank One, for the ratable benefit of the Banks, with respect to each Standby L/C
a nonrefundable Standby L/C fee of 1.0% per annum of the face amount of each
Standby L/C, payable in advance not later than the date of issuance thereof. In
addition, Bank One shall charge and retain for its own account its standard
issuance, amendment and negotiation fees, if any, with respect to the issuance
and administration of the Standby L/Cs.

         SECTION 3.2 PARTICIPATION OF L/CS.

                  (a) PURCHASE BY NCBC. NCBC shall be deemed to have purchased
from Bank One participations in all Standby L/Cs issued pursuant to this
Agreement or which are currently outstanding which may hereafter be renewed or
otherwise extended or modified. Such participations shall be in an amount equal
to the Revolving Credit Loan Commitment Percentage for NCBC. All interest
thereon and all fees and commissions, other than Bank One's standard issuance,
amendment and negotiation fees, with respect to the issuance or renewal of such
Standby L/Cs shall be shared ratably by the Banks in accordance with their
respective Revolving Credit Loan Commitment Percentage.

                  (b) AMENDMENT OF L/C. If any such Standby L/C is amended
whereby the amount is increased or decreased, each Bank's share of participation
shall be increased or decreased accordingly to its Revolving Credit Loan
Commitment Percentage.

                  (c) PAYMENTS. If the Borrowers do not immediately reimburse
Bank One for amounts funded under draws under Standby L/Cs, NCBC shall make
payment to Bank One in an amount equivalent to its participation in the Standby
L/Cs at Bank One's address set forth in Section 11.4 hereof, and in any event
not later than the time of payment provided for in the terms and conditions of
the applicable Standby L/C Applications. NCBC's obligation to purchase such
participations shall be primary, and not subject to any condition, precedent or
otherwise, except the issuance of the subject Standby L/C.

         Until payment of NCBC's participation to Bank One, Bank One shall be
entitled to all amounts of credits received by Bank One or either Bank from the
Borrowers, whether by voluntary payment, realization upon any security or
exercise of the right of setoff, or by payment from any source, except, that
upon default of the Borrowers, all payments received by either Bank shall be
applied in the proportion set forth in Section 8.2.

                  (d) NO LIABILITY. Bank One shall not be liable to NCBC for any
action taken or omitted with respect to the Standby L/Cs unless caused by its
own gross negligence or willful misconduct. Bank One shall exercise the same
care as in dealing with its own letters of credit, but shall not be responsible
in any manner to ascertain or

                                      -29-

inquire as to the financial condition of the Borrowers, or the Borrowers'
authority to execute the Standby L/C Applications, or the existence or possible
existence of any default under the Standby L/C Applications.

         SECTION 3.3 FURTHER ASSURANCES. The Borrowers hereby agree, from time
to time, to do and perform any and all acts and to execute any and all further
instruments reasonably requested by Bank One and/or the Agent to more fully
effect the purposes of this Agreement and the issuance of Standby L/Cs
hereunder, and further agree to execute any and all instruments reasonably
requested by Bank One and/or the Agent in connection with the obtaining and/or
maintaining of any insurance coverage, if any, applicable to any Standby L/C.

         SECTION 3.4 OBLIGATIONS ABSOLUTE. The Standby L/C payment obligations

connection with this Agreement, the Standby L/C Applications, the transactions
contemplated herein and therein, or any unrelated transaction;

                  (b) any statement or any other document presented under any
Standby L/C proving to be forged, fraudulent, invalid or insufficient in any
respect or any statement therein being untrue or inaccurate in any respect;

                  (c) payment by Bank One under any Standby L/C against
presentation of a draft or certificate which does not comply with the terms of
such Standby L/C, provided that Bank One has made such payment to the
beneficiary set forth on the face of such Standby L/C, as the case may be, and
Bank One has not made such payment negligently or with willful misconduct; or

                  (d) any other circumstances or happening whatsoever, whether
or not similar to any of the foregoing.

its business or because of the character of the properties owned or leased by it
or the transaction of its business, failure to be so qualified would have a
Material Adverse Effect or where failure to qualify would affect the ability of
the Borrower to enforce any of its material rights, and (iv) is in compliance
with all Requirements of Law except to the extent that the failure to comply
therewith would not, in the aggregate, have a Material Adverse Effect and would
not materially and adversely affect the ability of the Borrower to perform its

authority (i) to enter into this Agreement and all other Facility Documents,

other Facility Documents.

         SECTION 5.3 BINDING AGREEMENTS. This Agreement constitutes, and the
Notes and all other Facility Documents, when executed and delivered pursuant
hereto for value received, shall constitute, the valid and legally binding
obligations of each Borrower, enforceable in accordance with their respective
terms, except as enforcement of such terms may be limited by (i) bankruptcy,
insolvency, reorganization, moratorium, fraudulent conveyance, or similar laws
affecting creditors' rights generally, provided, however, that each Borrower
represents and warrants that no proceedings under such laws exist as of the date
of this Agreement, or (ii) equitable principles which may limit the availability
of the remedy of specific performance or other equitable remedies.

         SECTION 5.4 LITIGATION. There are no actions, suits, investigations or
administrative proceedings of or before any court, arbitrator or Governmental
Authority, pending or, to the knowledge of the Borrowers, threatened against any
Borrower or any of their

<PAGE>   40



respective properties or assets which: (i) either in any case or in the
aggregate, (x) an unfavorable outcome for any such Borrower is probable (as used
in this context, "probable" means, as reasonably determined by the Required
Banks, the prospects of the claimant not succeeding are judged to be extremely
doubtful and the prospects for success by any such Borrower in its defense are
judged to be slight), and (y) if so adversely determined, would have a Material
Adverse Effect; or (ii) question the validity of this Agreement or any other
Facility Documents or any action to be taken in connection with the transactions
contemplated hereby and thereby.

bound; (iii) do not and will not violate or conflict with, result in a breach of
or constitute (with notice, lapse of time, or otherwise) a default under any
material agreement, mortgage, indenture or contract to which any Borrower is a
party, or by which any Borrower's properties are bound, which violation would
have a Material Adverse Effect; or (iv) do not and will not result in the
creation or imposition of any lien, security interest, charge or encumbrance of
any nature whatsoever upon any property or assets of any Borrower.

         SECTION 5.6 TAXES. With respect to all taxable periods, each of the
Borrowers has filed all tax returns which are required to be filed and all
federal, state, municipal, franchise and other taxes shown to be due and payable
on such filed returns have been paid or have been reserved against, as required
by GAAP, and each of the Borrowers knows of no unpaid assessment against it.

or by which any of them or any of their respective assets or properties may be
bound, which default might have a Material Adverse Effect. None of the Borrowers

grounds under Section 4042 of ERISA for the termination of, or for the
appointment of a trustee to administer, any such Plan. None of the Borrowers nor
any member of its ERISA Group is in violation of any laws, ordinances,
governmental rules or regulations to which it is subject, including without

from or affecting any real property owned, leased or used by any Borrower (the
"Real Property") in any manner which violates any Environmental Laws governing
the use, storage, treatment, transportation, manufacture, refinement, handling,
production or disposal of Hazardous Materials, which violation would have a
Material Adverse Effect, and, to the best knowledge of each Borrower, no present
or prior owner of the Real Property or any tenant, subtenant, occupant, prior
tenant, prior subtenant or prior occupant has used Hazardous Materials on, from
or affecting the Real Property in any manner which violates any Environmental
Laws governing the use, storage, treatment, transportation, manufacture,

the business relationship of any Borrower with any customer or any group of
customers whose purchases individually or in the aggregate are material to the

modification upon less than 30 days advance written notice to the Borrowers, and
each Borrower shall so inform the Agent and the Banks of the receipt, and
contents, of any such notice. The Borrowers shall deposit with the Agent
certificates or other evidence satisfactory to it that (i) the insurance

Agreement, the Notes and the other Facility Documents, or any actual or proposed
use of proceeds of the Loans, regardless of whether or not the disbursement of
any Loans shall actually occur, unless any such loss, cost, expense, claim or
action are due to the gross negligence or willful misconduct of the Banks. The
provisions of this Section 6.10 shall survive the termination of this Agreement.

         If any claim, action or proceeding is made or brought against the Agent
and/or the Banks or any such officers, directors, agents and employees in
respect of which indemnity may be sought hereunder, the Agent shall give notice

or other notice of any kind, all of which are hereby waived by the Borrower.
Upon the happening of any of the foregoing Events of Default, the Agent and the

                                   ARTICLE IX

                                    THE AGENT
                                    ---------

         SECTION 9.1 APPOINTMENT. Each Bank hereby irrevocably designates and
appoints Bank One as Agent of such Bank under this Agreement, each of the Notes
and the other Facility Documents, and each Bank hereby irrevocably authorizes
Bank One, as Agent for such Bank, to take such action on its behalf under the
provisions of this Agreement, the Notes and the other Facility Document and to
exercise such powers and perform such duties as are expressly delegated to Agent
by the terms of this Agreement, the Notes and the other Facility Documents,
together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, any
Note or any other Facility Documents, the Agent shall not have any duties or
responsibilities, except those expressly set forth herein, or any fiduciary
relationship with any Banks, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement, any Note or any other Facility Documents, or otherwise exist against
the Agent.

         SECTION 9.2 DELEGATION OF DUTIES. The Agent may execute any of its
duties under this Agreement by or through agents or attorneys-in-fact and shall
be entitled to advice of counsel concerning all matters pertaining to such
duties. The Agent shall not be responsible for the negligence or misconduct of
any agents or attorneys-in-fact selected by it with reasonable care.

         SECTION 9.3 EXCULPATORY PROVISIONS. Neither the Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or affiliates shall be
(i) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Agreement, any Note or any other
Facility Documents (except for its or such Person's own gross negligence or
willful misconduct) or (ii) responsible in any manner to the Banks for any
recitals, statements, representations or warranties made by the Borrowers or any
officer thereof contained in this Agreement, any Note or any other Facility
Documents or in any certificate, report, statement or other document referred to
or provided for in, or received by the Agent under or in connection with, this
Agreement, any Note or any other Facility Documents or for the value, or
validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement, any Note or any other Facility Documents, or for any failure of any
Borrower to perform its obligations hereunder or thereunder. The Agent shall be
under no obligation to any Bank to ascertain or to inquire as to the observance
or performance of any of the agreements contained in, or conditions of, this
Agreement, any Note or any other Facility Documents, or to inspect the
properties, books or records of the Borrowers. The Agent shall have no liability
or responsibility to any of the Banks in connection with the collection or
payment of any sums due to the Banks by the Borrowers, the responsibility of the
Agent being only to account to the Banks for monies actually received by it. The
use of the term "agent" in this Agreement with reference to the Agent

                                      -51-

<PAGE>   57



is not intended to connote any fiduciary or other implied (or express)
obligations arising under agency doctrine of any applicable law. Instead, such
term is used merely as a matter of market custom and is intended to create or
reflect only an administrative relationship between independent contracting
parties.

         SECTION 9.4 RELIANCE BY AGENT. The Agent shall be entitled to rely, and
shall be fully protected in relying, upon any writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, facsimile,
telecopy, telex or teletype message, statement, order or other document or
conversation believed by it to be genuine and correct and to have been signed,
sent or made by the proper Person or Persons and upon advice and statements of
legal counsel (including, without limitation, counsel to the Borrowers),
independent accountants and other experts selected by the Agent. The Agent may
deem and treat the payee of any Note as the owner thereof for all purposes. The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement, any Note or any other Facility Documents unless it shall first
receive such advice or concurrence of the Banks or it shall first be indemnified
to its satisfaction by all Banks against any and all liability and expense which
may be incurred by it by reason of taking or continuing to take any such action.
The Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement, any Note or any other Facility Documents in
accordance with a request of the Banks, and such request and any action taken or
failure to act pursuant thereto shall be binding upon the Banks and all future
holders of the Notes.

         SECTION 9.5 NOTICE OF DEFAULT. The Agent shall not be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Agent has received notice from any Bank or the Borrowers
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default". If the Agent receives such a
notice, the Agent shall promptly give notice thereof to the Banks. The Agent
shall take such action with respect to such Default or Event of Default as shall
be reasonably directed by the Banks; provided that, unless and until the Agent
shall have received such directions, the Agent may (but shall not be obligated
to) take such action, or refrain from taking such action, with respect to such
Default or Event of Default as it shall reasonably deem advisable in the best
interest of the Banks.

         SECTION 9.6 NON-RELIANCE ON AGENT AND OTHER BANKS. Each Bank expressly
acknowledges that neither the Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates has made any representations
or warranties to it and that no act by the Agent hereinafter taken, including
any review of the affairs of the Borrowers, shall be deemed to constitute any
representation or warranty by the Agent to any Bank. Each Bank represents to the
Agent that it has, independently and without reliance upon the Agent or any
other Bank, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Borrowers and made its own decision to make its extensions of credit hereunder
and enter into this

                                      -52-

<PAGE>   58



Agreement. Each Bank also represents that it will, independently and without
reliance upon the Agent or any other Bank, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement, the Notes and the other Facility Documents, and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Borrowers. Except for notices, reports and other documents expressly required to
be furnished to the Banks by the Agent hereunder, the Agent shall not have any
duty or responsibility to provide any Bank with any credit or other information
concerning the business, operations, property, financial and other condition or
creditworthiness of the Borrowers which may come into the possession of the
Agent or any of its officers, directors, employees, agents, attorneys-in-fact or
affiliates.

         SECTION 9.7 INDEMNIFICATION. Each Bank agrees to indemnify the Agent in
its capacity as such (to the extent not reimbursed by the Borrowers and without
limiting the obligation of the Borrowers to do so), ratably according to the
respective Revolving Credit Loan Commitment Percentage, from and against any and
all liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expense or disbursements of any kind whatsoever which may at any
time (including, without limitation, at any time following the payment of the
Notes) be imposed on, incurred by or asserted against the Agent in any way
relating to or arising out of this Agreement, the Notes and the other Facility
Documents or any documents contemplated by or referred to herein or the
transactions contemplated hereby or any action taken or omitted by the Agent
under or in connection with any of the foregoing; provided that no Bank shall be
liable for the payment of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting solely from the Agent's gross negligence or willful misconduct. The
agreements in this Section 9.7 shall survive the payment of the Notes and all
other amounts payable hereunder and the other Facility Documents and the
termination of this Agreement and the other Facility Documents.

         SECTION 9.8 BANK ONE IN ITS INDIVIDUAL CAPACITY. Bank One and its
Affiliates may make loans to, accept deposits from and generally engage in any
kind of business with the Borrowers as though Bank One were not the Agent
hereunder. With respect to its Loans made or renewed by it and any Note issued
to it either as Bank One or the Agent, Bank One shall have the same rights and
powers under this Agreement as any Bank and may exercise the same as though it
were not the Agent, and the terms "Bank" and "Banks" shall include Bank One in
its individual capacity.

         SECTION 9.9 SUCCESSOR AGENT. The Agent may resign as agent at any time
by giving notice to the Banks and the Borrowers. Upon any such resignation, the
Required Banks shall have the right to appoint a successor Agent. If no
successor Agent shall have been so appointed by the Required Banks, and shall
have accepted such appointment, within 30 days after the retiring Agent gives
notice of resignation, then the retiring Agent

                                      -53-

<PAGE>   59



may, on behalf of the Banks, appoint a successor Agent, which shall be a
commercial bank organized or licensed under the laws of the United States or of
any State thereof and having a combined capital and surplus of at least $100
million. Upon the acceptance of its appointment as Agent hereunder by a
successor Agent, such successor Agent shall succeed to the rights, powers and
duties of the retiring Agent, and the term "Agent" shall mean such successor
Agent effective upon its appointment, and the retiring Agent's rights, powers
and duties as Agent shall be terminated, without any other or further act or
deed on the part of such retiring Agent or any of the parties to this Agreement
or any holders of the Notes. After any retiring Agent's resignation hereunder as
Agent, the provisions of this Article VIII shall inure to its benefit as to any
actions taken or omitted to be taken by it while it was Agent under this
Agreement.

                             CHANGE IN CIRCUMSTANCES
                             -----------------------

         SECTION 10.1 BASIS FOR DETERMINING INTEREST RATE INADEQUATE OR UNFAIR.
If on or prior to the funding of a Loan at, or converting the Interest Rate on a
Loan to, the Eurodollar Rate:

                  (a) any Bank determines that deposits in Dollars (in the
applicable amounts) are not being offered to the Bank in the Eurodollar market
for such Interest Period, or

                  (b) any Bank determines that the Eurodollar Rate, as
determined by the Agent, will not adequately and fairly reflect the cost to such
Bank of funding the Eurodollar Rate Loans for such Interest Period, the Bank
shall forthwith give notice thereof to the Agent and the Borrowers, whereupon
until the Bank notifies the Agent and the Borrowers that the circumstances
giving rise to such suspension no longer exist, (i) the obligations of the Banks
to make Eurodollar Rate Loans or to continue or convert outstanding Loans as or
into Eurodollar Rate Loans shall be suspended, and (ii) each outstanding
Eurodollar Rate Loan shall be converted into a Base Rate Loan on the date set
forth in such notice. Unless the Borrowers notifies the Agent at least one (1)
Business Day before the date of any Eurodollar Rate Loan borrowing for which a
Notice of Borrowing has previously been given that it elects not to borrow on
such date, such borrowing shall instead be made as a Base Rate Loan.

         SECTION 10.2 ILLEGALITY AND IMPOSSIBILITY. In the event that any
applicable law, treaty, rule or regulation (whether domestic or foreign) now or
hereafter in effect and whether or not presently applicable to any Bank, or any
interpretation or administration thereof by any Governmental Authority charged
with the interpretation or administration thereof, or compliance by any Bank
with any request or directive of such authority (whether or not having the force
of law), including without limitation exchange controls, shall make

                                      -54-

<PAGE>   60



it unlawful or impossible for any Bank to make, maintain or fund its Eurodollar
Rate Loans and such Bank shall forthwith give notice thereof to the Agent and
the Borrowers, whereupon until such Bank notifies the Borrowers that the
circumstances giving rise to such suspension no longer exist, the obligation of
the Banks to make Eurodollar Rate Loans, or to convert outstanding Base Rate
Loans to Eurodollar Rate Loans, shall be suspended. If such notice is given,
each Eurodollar Rate Loan of the Banks then outstanding shall be converted to a
Base Rate Loan immediately.

         SECTION 10.3 INCREASED COST AND REDUCED RETURN.

                  (a) In the event that any applicable law, treaty, rule or
regulation (whether domestic or foreign) now or hereafter in effect and whether
or not presently applicable to any Bank, or any interpretation or administration
thereof by any Governmental Authority charged with the interpretation or
administration thereof, or compliance by any Bank with any guideline, request or
directive of any such authority (whether or not having the force of law), shall
(i) affect the basis of taxation of payments to any Bank of any amounts payable
by the Borrowers under this Agreement or any other Facility Document (other than
taxes imposed on the overall net income of the Bank by the jurisdiction, or by
any political subdivision or taxing authority of such jurisdiction, in which the
Bank has its principal office), or (ii) impose, modify or deem applicable any
Eurodollar Reserve Percentage or any such requirement imposed by the Board of
Governors of the Federal Reserve System, special deposit, insurance assessment
or similar requirement against assets of, deposits with or for the account of,
or credit extended by, any Bank, or (iii) impose on any Bank or the London
interbank market any other condition affecting the Eurodollar Rate Loans, the
Notes or any Bank's obligation to make Eurodollar Rate Loans and the result of
any of the foregoing is to increase the cost to any Bank of making, funding or
maintaining any Eurodollar Rate Loan, or to reduce the amount of any sum
received or receivable by the Bank under this Agreement or under any Note with
respect thereto, by any amount deemed by any Bank to be material, then, within
15 days after demand by such Bank, the Borrowers shall pay to the Bank such
additional amount or amounts sufficient to compensate the Bank for such
increased cost or reduction.

                  (b) In the event that any applicable law, treaty, rule or
regulation (whether domestic or foreign) now or hereafter in effect and whether
or not presently applicable to any Bank or any interpretation or administration
thereof by any Governmental Authority charged with the interpretation or
administration thereof, or compliance by any Bank with any guideline, request or
directive of any such authority (whether or not having the force of law),
including any risk-based capital guidelines, affects or would affect the amount
of capital required or expected to be maintained by any Bank (or any corporation
controlling such Bank) and the Bank determines that the amount of such capital
is increased by or based upon the existence of the Bank's obligations hereunder
and such increase has the effect of reducing the rate of return on the Bank's
(or such controlling corporation's) capital as a consequence of such obligations
hereunder to a level below that which the Bank (or

                                      -55-

<PAGE>   61



such controlling corporation) could have achieved but for such circumstances
(taking into consideration its policies with respect to capital adequacy) by an
amount deemed by the Bank to be material, then, within 15 days after demand by
the Bank, the Borrowers shall pay to the Bank such additional amount or amounts
sufficient to compensate the Bank for such reduction.

                  (c) A Bank shall promptly notify the Agent and the Borrowers
of any event of which it has knowledge, occurring after the date hereof, which
will entitle the Bank to compensation pursuant to this Section 10.3. A
certificate of the Bank claiming compensation under this Section 10.3 and
setting forth the additional amount or amounts to be paid to it hereunder shall
be conclusive and binding for all purposes, absent manifest error. In
determining such amount, the Bank may use any reasonable averaging and
attribution methods.

         SECTION 10.4 TAXES.

                  (a) For the purposes of this Section 10.4, the following terms
have the following meanings:

                        "TAXES" shall mean any and all present or future taxes,
duties, levies, imposts, deductions, charges or withholdings with respect to any
payment by the Borrowers pursuant to this Agreement or under any Note, and all
liabilities with respect thereto, excluding, in the case of any Bank, taxes
imposed on its income, and franchise or similar taxes imposed on it, by a
jurisdiction under the laws of which the Bank is organized, in which its
principal executive office is located or the State of Ohio.

                        "OTHER TAXES" shall mean any present or future stamp or
documentary taxes and any other excise or property taxes, or similar charges or
levies, which arise from any payment made pursuant to this Agreement or under
any Note or from the execution or delivery of, or otherwise with respect to,
this Agreement or, any Note or any other Facility Document.

                  (b) Any and all payments by the Borrowers to or for the
account of any Bank or the Agent hereunder or under any Note or other Facility
Document shall be made without deduction for any Taxes or Other Taxes; provided
that, if the Borrowers shall be required by law to deduct any Taxes or Other
Taxes from any such payments, (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 10.4) such Bank or the
Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made, (ii) the Borrowers shall make such
deductions, (iii) the Borrowers shall pay the full amount deducted to the
relevant taxation authority or other Governmental Authority in accordance with
applicable law, and (iv) the

                                      -56-

<PAGE>   62



Borrowers shall furnish to the Agent, at its address referred to in Section
11.4, the original or a certified copy of a receipt evidencing payment thereof.

                  (c) The Borrowers agree to indemnify each Bank and the Agent
for the full amount of Taxes or Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable
under this Section 10.4) paid by such Bank or the Agent (as the case may be) and
any liability (including penalties, interest and expenses) arising therefrom or
with respect thereto; provided, however, if any Bank or the Agent successfully
defends against any claim so asserted, and such outcome would also be applicable
as to all of such Bank's transactions with customers similarly or analogously
situated, the indemnification provided for shall be proportionally reduced. This
indemnification provided for in this subsection (c) shall be paid within 15 days
after such Bank or the Agent (as the case may be) makes demand therefor.

         SECTION 10.5 BASE RATE LOANS SUBSTITUTED FOR AFFECTED EURODOLLAR RATE
LOANS. If (a) the obligation of any Bank to make, or convert outstanding Loans
to, Eurodollar Rate Loans has been suspended pursuant to the terms of this
Agreement, or (b) any Bank has demanded compensation under Section 10.3 or 10.4
with respect to its Eurodollar Rate Loans and the Borrowers shall, by at least
five Business Days' prior notice to such through the Agent, have elected that
the provisions of this Section 10.5 shall apply to such Bank, then, unless and
until such Bank notifies the Agent and the Borrowers that the circumstances
giving rise to such suspension or demand for compensation no longer exist:

                  (a) all Loans which would otherwise be made by the Bank as (or
         continued as or converted into) Eurodollar Rate Loans shall instead be
         Base Rate Loans; and

                  (b) after each of its Eurodollar Rate Loans has been repaid
         (or converted to a Base Rate Loan), all payments of principal which
         would otherwise be applied to repay such Eurodollar Rate Loans shall be
         applied to repay its Base Rate Loans instead.

If the Bank notifies the Agent and the Borrowers that the circumstances giving
rise to such notice no longer apply, the principal amount of each such Base Rate
Loan shall be converted into a Eurodollar Rate Loan on the date set forth in
such notice.

                                   ARTICLE XI

                                  MISCELLANEOUS
                                  -------------

         SECTION 11.1 EXPENSES. Whether or not the transactions herein
contemplated shall be consummated, the Borrowers agree to pay all out-of-pocket
expenses (including

                                      -57-

<PAGE>   63



reasonable fees and expenses of counsel) of the Agent and the Banks incurred in
connection with the preparation of this Agreement, the Notes, any amendments or
supplements to this Agreement and the other Facility Documents, any audit,
appraisal or other such service deemed necessary or desirable by the Agent or
the Banks for the preparation of the Agreement, underwriting documents or
enforcing the Agent's and the Banks' rights hereunder, and all out-of-pocket
expenses (including reasonable fees and expenses of their respective counsel)
incidental to the enforcement of the rights of the Agent and the Banks under any
provisions of this Agreement, the Notes and any other Facility Document.

         SECTION 11.2 COVENANTS TO SURVIVE, BINDING AGREEMENT. This Agreement
shall be binding upon and inure to the benefit of the Agent, the Banks, the
Borrowers and their respective successors or assigns; provided, however, that
the Borrowers may not assign or otherwise dispose of any of its rights or
obligations hereunder. All covenants, agreements, warranties and representations
made herein, and in all certificates and documents delivered in connection with
this Agreement by or on behalf of the Borrowers shall survive the execution and
delivery hereof and thereof, and all such covenants, agreements, representations
and warranties shall inure to the respective successors and assigns of the Banks
whether or not so expressed.

         SECTION 11.3 WAIVERS. No failure on the part of the Agent or the Banks
to exercise and no delay in exercising any right or remedy hereunder or under
the Notes or any other Facility Documents shall operate as a waiver thereof, nor
shall any single or partial exercise by the Agent or the Banks of any right,
remedy or power hereunder thereunder preclude any other right, remedy or power.
The rights, remedies and powers provided herein, in the Notes and the other
Facility Documents are cumulative and not exclusive of any other rights,
remedies or powers which the Agent, the Banks or any holder of the Notes, would
otherwise have. Notice to or demand on the Borrowers in any circumstance in
which the terms of this Agreement, the Notes or the other Facility Documents do
not require notice or demand to be given shall not entitle the Borrowers to any
other or further notice or demand in similar or other circumstances or
constitute a waiver of the rights of the Agent, the Banks or the holder of any
Notes to take any other further action in any circumstances without notice or
demand.

         SECTION 11.4 NOTICES. Notice from one party to another relating to this
Agreement shall be deemed effective if made in writing (including
telecommunications) and delivered to the recipient's address, telex number or

                                           9711 Lancaster Road, S. E.

                                           Attention: Robert J. Gilker, Esq.

         SECTION 11.5 SEVERABILITY, ENTIRE AGREEMENT, EFFECTIVENESS. Every
provision of this Agreement, the Notes and the other Facility Documents is
intended to be severable; if any term or provision of this Agreement, any Note
or other Facility Document shall be invalid, illegal or unenforceable for any
reason whatsoever, the validity, legality and enforceability of the remaining
provisions hereof or thereof shall not in any way be affected or impaired
thereby. All exhibits and schedules to this Agreement shall be annexed hereto
and shall be deemed to be part of this Agreement. This Agreement and the
exhibits and schedules attached hereto and the other Facility Documents embody
the entire agreement and understanding between the Borrowers, the Agent and the
Banks and supersede all prior agreements and understandings relating to the
subject matter hereof. This Agreement shall become effective upon receipt by the
Agent of counterparts hereof signed by each of the parties hereto (or, in the
case of any party as to which an executed counterpart shall not have been
received, receipt by the Agent in form satisfactory to it of telegraphic,
facsimile or other written confirmation from such party of execution of a
counterpart hereof by such party).

         SECTION 11.6 GOVERNING LAW; VENUE. This Agreement, the Notes and all
other Facility Documents are being delivered, and are intended to be performed
in, the State of Ohio and shall be construed and enforceable in accordance with,
and governed by, the laws of the State of Ohio. Each Borrower agrees that any
legal suit, action or proceeding arising out of or related to this Agreement or
any other Facility Document or the transactions contemplated hereby and thereby
may be instituted in a state of federal court of appropriate jurisdiction in
Franklin County, Ohio, waives any objection which it may have now or hereafter
to the venue of any such suit, action or proceeding, and irrevocably submits to
the jurisdiction of any such court in any such suit, action or proceeding.

         SECTION 11.7 SECURITY AND RIGHT OF SETOFF. Each Borrower hereby grants
to the Banks a right of setoff for all Setoff Obligations of the Borrower to
each Bank hereunder in and to any and all moneys of the Borrower and the
proceeds thereof now or hereafter held or received by or in transit to either
Bank from or for the account of the Borrower, whether for safekeeping, pledge,
transmission, collection or otherwise, and also upon any and all deposits
(general and special), account balances and credits of the Borrower with

                                      -60-

<PAGE>   66



either Bank at any time existing. Each Bank is hereby expressly and irrevocably
authorized by the Borrower at any time and from time to time upon or after the
occurrence of an Event of Default, without notifying the Borrower, to setoff and
appropriate all items hereinbefore referred to in this Section 11.7. All items
so setoff and appropriated shall be delivered to the Agent for delivery to and
allocation among the Banks in accordance with each Bank's respective Revolving
Credit Loan Commitment Percentage and shall be applied first by each Bank to the
Borrower's obligations hereunder and the other Facility Documents and thereafter
to all other Setoff Obligations of the Borrower to such Bank, and the Borrower
shall continue to be liable to the Banks for any deficiency with interest at the
applicable rates. Each Borrower hereby irrevocably consents that the Banks shall
have the right of possessing, setting-off, appropriating and applying such items
for the benefit of the Banks and paying or delivering over to the Banks any of
such items for application in accordance with the provisions hereof. Any sums so
set-off shall be held in trust by the Agent for the pro rata benefit of all
Banks with respect to their respective Loans.

         SECTION 11.8 AMENDMENTS AND WAIVERS. Any provision of this Agreement,
the Notes or any other Facility Document may be amended or waived if, but only
if, such amendment or waiver is in writing and is signed by the Borrower and the
Required Banks (and, if the rights or duties of the Agent are affected thereby,
by the Agent); provided that no such amendment or waiver shall, unless signed by
all the Banks, (i) increase or decrease the Commitment of any Bank (except for a
ratable decrease in the Commitments of all Banks) or subject any Bank to any
additional obligation, (ii) reduce the principal of or rate of interest on any
Loan or any fees hereunder, (iii) postpone the date fixed for any payment of
principal of or interest on any Loan or any fees hereunder or for any scheduled
reduction or termination of any Commitment, (iv) change the aggregate amount of
Loans required to be repaid on any date pursuant to this Agreement, (v) amend or
waive this Section 11.8 or any of the financial covenants set forth in Section
7.6, (vi) change the Loan Commitment Percentage of any Bank, (vii) change the
aggregate unpaid principal amount of the Notes, or (viii) or the definition of
Required Banks.

         SECTION 11.9 TAXES AND FEES. Should any tax (other than a tax based
upon the net income of the Banks) or any recording or filing fees become payable
in respect of this Agreement, the Notes or any other Facility Document or any
amendment, modification or supplement hereof or thereof, the Borrowers agrees,
jointly and severally, to pay the same together with any interest or penalties
thereon and agree to hold the Banks harmless with respect thereof.

         SECTION 11.10 COUNTERPARTS. This Agreement may be executed in any
number of counterparts, each of which shall be an original and all of which
shall constitute one agreement. It shall not be necessary in making proof of
this Agreement or of any document required to be executed and delivered in
connection herewith to produce or account for more than one counterpart.


                                      -61-

<PAGE>   67



         SECTION 11.11 EFFECTIVE DATE. This Agreement shall be effective at such
time as executed counterparts of this Agreement have been delivered by the
Borrowers to the Agent.

         SECTION 11.12 WAIVER OF JURY TRIAL. THE BANKS, THE AGENT AND THE
BORROWERS, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH
COUNSEL, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT ANY OF THEM
MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING OUT OF THIS
AGREEMENT, THE NOTES, THE OTHER FACILITY DOCUMENTS, OR ANY RELATED INSTRUMENT OR
AGREEMENT, OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREBY, OR ANY COURSE OF
CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTIONS OF ANY OF
THEM. NEITHER THE BANKS, THE AGENT NOR THE BORROWERS SHALL SEEK TO CONSOLIDATE,
BY COUNTERCLAIM OR OTHERWISE, ANY ACTION IN WHICH A JURY TRIAL HAS BEEN WAIVED
WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT BE OR HAS NOT BEEN WAIVED.
THESE PROVISIONS SHALL NOT BE DEEMED TO HAVE BEEN MODIFIED IN ANY RESPECT OR
RELINQUISHED BY THE BANKS, THE AGENT OR THE BORROWERS EXCEPT BY A WRITTEN
INSTRUMENT EXECUTED BY ALL OF THEM.

         SECTION 11.13 ARBITRATION. The Banks, the Agent and Borrowers agree
that upon the written demand of any party, whether made before or after the
institution of any legal proceedings, but prior to the rendering of any judgment
in that proceeding, all disputes, claims and controversies between them, whether
individual, joint, or class in nature, arising from this Agreement, any other
Facility Document or otherwise, including without limitation contract disputes
and tort claims, shall be resolved by binding arbitration pursuant to the
Commercial Rules of the American Arbitration Association ("AAA"). Any
arbitration proceeding held pursuant to this arbitration provision shall be
conducted in the city nearest the Borrower's address having an AAA regional
office, or at any other place selected by mutual agreement of the parties. This
arbitration provision shall not limit the right of any party during any dispute,
claim or controversy to seek, use, and employ ancillary, or preliminary rights
and/or remedies, judicial or otherwise, for the purposes of realizing upon,
preserving, protecting, foreclosing upon or proceeding under forcible entry and
detainer for possession of, any real or personal property, and any such action
shall not be deemed an election of remedies. Such remedies include, without
limitation, obtaining injunctive relief or a temporary restraining order,
invoking a power of sale under any deed of trust or mortgage, obtaining a writ
of attachment or imposition of a receivership, or exercising any rights relating
to personal property, including taking or disposing of such property with or
without judicial process pursuant to Article 9 of the Uniform Commercial Code or
when applicable, a judgment by confession of judgment. Any disputes, claims or
controversies concerning the lawfulness or reasonableness of an act, or exercise
of any right or remedy concerning any property, including any claim to rescind,
reform or otherwise modify any agreement relating to any property, shall also be
arbitrated; provided, however that no

                                      -62-

<PAGE>   68



arbitrator shall have the right or the power to enjoin or restrain any act of
either party. Judgement upon any award rendered by any arbitrator may be entered
in any court having jurisdiction. Nothing in this arbitration provision shall
preclude either party from seeking equitable relief from a court of competent
jurisdiction. The statute of limitations, estoppel, waiver, laches and similar
doctrines which would otherwise be applicable in an action brought by a party
shall be applicable in any arbitration proceeding, and the commencement of an
arbitration proceeding shall be deemed the commencement of any action for these
purposes. The Federal Arbitration Act (Title 9 of the United States Code) shall
apply to the construction, interpretation, and enforcement of this arbitration
provision.

         SECTION 11.14 WAIVER OF SUBROGATION. Each Borrower expressly waives any
and all rights of subrogation, contribution, reimbursement, indemnity,
exoneration, implied contract, recourse to security or any other claim
(including any claim, as that term is defined in the federal Bankruptcy Code,
and any amendments) which such Borrower may now have or later acquire against
any other Borrowers, any other entity directly or contingently liable for the
obligations of the Borrowers under this Agreement, the Notes and all other
Facility Documents, arising from the existence or performance of such Borrower's
obligations under this Agreement and the other Facility Documents.

<PAGE>   3



         4. OPTION RIGHTS.

            (a) The Committee may from time to time authorize grants to
Participants of options to purchase Common Shares upon such terms and conditions
as the Committee may determine in accordance with the following provisions:

                (i) Each grant shall specify the number of Common Shares to
which it pertains.

                (ii) Each grant shall specify an Option Price per Common Share,
which in the case of Incentive Options, shall be equal to or greater than the
Market Value per Share on the Date of Grant and, in the case of other options,
shall not be less than eighty-five percent (85%) of the Market Value per Share
on the Date of Grant.

                (iii) Each grant shall specify the form of consideration to be
paid in satisfaction of the Option Price and the manner of payment of such
consideration, which may include (A) cash in the form of currency or check or
other cash equivalent acceptable to the Corporation, (B) nonforfeitable,
unrestricted Common Shares, which are already owned by the Optionee and have a
value at the time of exercise that is equal to the Option Price, (C) any other
legal consideration, including, without limitation, promissory notes, that the
Committee may deem appropriate, including without limitation any form of
consideration authorized under Section 4(a)(iv) below, on such basis as the
Committee may determine in accordance with this Plan and (D) any combination of
the foregoing.

                (iv) Any grant may provide for deferred payment of the Option
Price from the proceeds of sale through a bank or broker on the date of exercise
of some or all of the Common Shares to which the exercise relates.

                (v) Any grant may provide for the automatic grant to the
Optionee of Reload Option Rights upon the exercise of Option Rights, including
Reload Option Rights, for Common Shares or any other noncash consideration
authorized under Sections 4(a)(iii) above.

                (vi) Successive grants may be made to the same Participant
regardless of whether any Option Rights previously granted to such Participant
remain unexercised.

                (vii) Each grant shall specify the period or periods of
continuous employment of the Optionee by the Corporation or any Subsidiary that
are necessary before the Option Rights or installments thereof shall become
exercisable, and any grant may provide for the earlier exercisability of such
rights in the event of retirement, death or disability of the Participant or a
change in control of the Corporation or other similar transaction or event.

                (viii) Option Rights granted under this Plan may be (A) options
that are intended to qualify under particular provisions of the Code, including
without limitation Incentive Stock Options, (B) options that are not intended to
so qualify or (C) combinations of the foregoing.



                                       -3-

<PAGE>   4



                (ix) No Option Right granted under this Plan may be exercised
more than 10 years from the Date of Grant.

                (x) Each grant shall be evidenced by an agreement, which shall
be executed on behalf of the Corporation by any officer thereof and delivered to
and accepted by the Optionee and shall contain such terms and provisions as the
Committee may determine consistent with this Plan.

         (b) (i) Notwithstanding the above, each director who is a Nonemployee
Director is hereby granted, effective the close of business on the first
business day after (1) the date of the first annual meeting of shareholders
occurring after the date of this Plan at which he or she is elected a Director,
an option to purchase 2,000 Common Shares, and (2) the date of each subsequent
annual meeting of shareholders at which he or she is elected a Director, an
option to purchase 1,000 Common Shares.

             (ii) All options granted pursuant to this Section 2(b)(i) hereof
shall be non-statutory options not intended to qualify under Section 422 of the
Code and shall be evidenced by an agreement, which shall be executed on behalf
of the Corporation by any officer thereof and delivered to and accepted by such
Nonemployee Director, and which agreement shall be in the form attached hereto
as Exhibit A.

             (iii) The Option Price per Common Share shall be equal to 100% of
the Market Value per Share as of the date such option is granted, shall be
exercisable in full one year following the date of grant and shall expire ten
years from the date of grant, unless terminated earlier in accordance with the
stock option agreement.

         5. TRANSFERABILITY.

            (a) No Option Right or other derivative security (as that term is
used in Rule 16b-3) awarded under this Plan shall be transferable by a
Participant other than by will or the laws of descent and distribution or, other
than with respect to an Incentive Stock Option, a qualified domestic relations
order, as defined in the Code. Option Rights shall be exercisable during a
Participant's lifetime only by the Participant or, in the event of the
Participant's legal incapacity, by his guardian or legal representative acting
in a fiduciary capacity on behalf of the Participant under state law and court
supervision. Notwithstanding the foregoing, the Committee, in its sole
discretion, may provide for transferability of particular awards under this Plan
so long as such provisions will not disqualify the exemption for other awards
under Rule 16b-3.

            (b) Any award made under this Plan may provide that all or any part
of the Common Shares that are to be issued or transferred by the Corporation
upon the exercise of Option Rights shall be subject to further restrictions upon
transfer.

         6. ADJUSTMENTS. The Committee may make or provide for such adjustments
in the (a) number of Common Shares covered by outstanding Option Rights, (b)
prices per share applicable to such Option Rights, and (c) kind of shares
(including shares of another issuer) covered thereby, as the Committee in its
sole discretion may in good faith determine to be equitably required in order to
prevent dilution or enlargement of the rights of Participants that otherwise
would result from


                                       -4-

<PAGE>   5



(x) any stock dividend, stock split, combination of shares, recapitalization or
other change in the capital structure of the Corporation, (y) any merger,
consolidation, spin-off, spin-out, split-off, split-up, reorganization, partial
or complete liquidation or other distribution of assets, issuance of rights or
warrants to purchase securities or (z) any other corporate transaction or event
having an effect similar to any of the foregoing. In the event of any such
transaction or event, the Committee may provide in substitution for any or all
outstanding awards under this Plan such alternative consideration as it may in
good faith determine to be equitable under the circumstances and may require in
connection therewith the surrender of all awards so replaced. Moreover, the
Committee may on or after the Date of Grant provide in the agreement evidencing
any award under this Plan that the holder of the award may elect to receive an
equivalent award in respect of securities of the surviving entity of any merger,
consolidation or other transaction or event having a similar effect, or the
Committee may provide that the holder will automatically be entitled to receive
such an equivalent award. In any case, such substitution of securities shall not
require the consent of any person who is granted awards pursuant to this Plan.

         7. FRACTIONAL SHARES. The Corporation shall not be required to issue
any fractional Common Shares pursuant to this Plan. The Committee may provide
for the elimination of fractions or for the settlement thereof in cash.

         8. WITHHOLDING TAXES. To the extent that the Corporation is required to
withhold federal, state, local or foreign taxes in connection with any payment
made or benefit realized by a Participant or other person under this Plan, and
the amounts available to the Corporation for such withholding are insufficient,
it shall be a condition to the receipt of such payment or the realization of
such benefit that the Participant or such other person make arrangements
satisfactory to the Corporation for payment of the balance of such taxes
required to be withheld. At the discretion of the Committee, such arrangements
may include relinquishment of a portion of such benefit. The Corporation and any
Participant or such other person may also make similar arrangements with respect
to the payment of any taxes with respect to which withholding is not required.

         9. PARTICIPATION BY EMPLOYEES OF A LESS-THAN-80-PERCENT SUBSIDIARY. As
a condition to the effectiveness of any grant or award to be made hereunder to a
Participant who is an employee of a Less-Than-80-Percent Subsidiary, regardless
whether such Participant is also employed by the Corporation or another
Subsidiary, the Committee may require the Less-Than-80-Percent Subsidiary to
agree to transfer to the Participant (as, if and when provided for under this
Plan and any applicable agreement entered into between the Participant and the
Less-Than-80-Percent Subsidiary pursuant to this Plan) the Common Shares that
would otherwise be delivered by the Corporation upon receipt by the
Less-Than-80-Percent Subsidiary of any consideration then otherwise payable by
the Participant to the Corporation. Any such award may be evidenced by an
agreement between the Participant and the Less-Than-80-Percent Subsidiary, in
lieu of the Corporation, on terms consistent with this Plan and approved by the
Committee and the Less-Than-80-Percent Subsidiary. All Common Shares so
delivered by or to a Less-Than-80-Percent Subsidiary will be treated as if they
had been delivered by or to the Corporation for purposes of Section 3 of this
Plan, and all references to the Corporation in this Plan shall be deemed to
refer to the Less-Than-80-Percent Subsidiary except with respect to the
definitions of the Board and the Committee and in other cases where the context
otherwise requires.

         10. CERTAIN TERMINATIONS OF EMPLOYMENT, HARDSHIP AND APPROVED LEAVES OF
ABSENCE. Notwithstanding any other provision of this Plan to the contrary, in
the event of termination of employment by reason of death, disability, normal
retirement, early retirement with the consent of the Corporation, termination of
employment to enter public service with the consent of the Corporation or leave
of absence approved by the Corporation, or in the event of hardship or other
special circumstances, of a Participant who holds an Option Right that is not
immediately and fully exercisable, the Committee may in its sole discretion take
any action that it deems to be equitable under the circumstances or in the best
interests of the Corporation, including without limitation waiving or modifying
any limitation or requirement with respect to any award under this Plan.

         11. ADMINISTRATION OF THE PLAN.

            (a) This Plan shall be administered by the Compensation Committee of
the Board appointed from time to time by the Board of Directors of the
Corporation. The Committee shall be composed of not less than two members of the
Board, each of whom shall be a "disinterested person" within the meaning of Rule
16b-3 and an "outside director" within the meaning of Section 162(m) of the
Code. A majority of the Committee shall constitute a quorum, and the acts of the
members of the Committee who are present at any meeting thereof at which a
quorum is present, or acts unanimously approved by the members of the Committee
in writing, shall be the acts of the Committee.

            (b) The interpretation and construction by the Committee of any
provision of this Plan or of any agreement, notification or document evidencing
the grant of Option Rights, and any determination by the Committee pursuant to
any provision of this Plan or any such agreement, notification or document,
shall be final and conclusive. No member of the Committee shall be liable for
any such action taken or determination made in good faith.

         12. AMENDMENTS AND OTHER MATTERS.

            (a) This Plan may be amended from time to time by the Committee, but
except as expressly authorized by this Plan no such amendment shall increase the
maximum number of shares specified in Section 3(a) of this Plan (except that
adjustments authorized by Section 6 of this Plan shall not be limited by this
provision), or cause Rule 16b-3 to become inapplicable to this Plan, without the
further approval of the shareholders of the Corporation, unless permitted by
Rule 16b-3. Without limiting the generality of the foregoing, the Committee may
amend this Plan to eliminate provisions which are no longer necessary as a
result of changes in tax or securities laws or regulations, or in the
interpretation thereof.

            (b) With the concurrence of the affected Optionee, the Committee may
cancel any agreement evidencing Option Rights or any other award granted under
this Plan. In the event of such cancellation, the Committee may authorize the
granting of new Option Rights or other awards hereunder, which may or may not
cover the same number of Common Shares that had been the subject of the prior
award, at such Option Price and subject to such other terms, conditions and
discretions as would have been applicable under this Plan had the canceled
Option Rights or other awards been granted.

            (c) The Committee may, in its sole discretion, accelerate the time
at which any Option Right may be exercised. The Committee also may permit
Participants to elect to defer the issuance of Common Shares pursuant to such
rules, procedures or programs as it may establish for purposes of this Plan. The
Committee also may provide that deferred settlements include the payment or
crediting of interest on the deferral amounts, or the payment or crediting of
dividend equivalents where the deferral amounts are denominated in Common
Shares.

            (d) This Plan shall not confer upon any Participant any right with
respect to continuance of employment or other service with the Corporation or
any Subsidiary and shall not interfere in any way with any right that the
Corporation or any Subsidiary would otherwise have to terminate any
Participant's employment or other service at any time.

            (e) To the extent that any provision of this Plan would prevent any
Option Right that was intended to qualify under particular provisions of the
Code from so qualifying, such provision of this Plan shall be null and void with
respect to such Option Right; provided, however, that such provision shall
remain in effect with respect to other Option Rights, and there shall be no
further effect on any provision of this Plan.

                                      LEASE
                                      -----



         THIS LEASE ("LEASE"), is made this 11th day of February, 1998,
effective as of December 1, 1997, by and between MONTE R. BLACK AND SUSAN K.
BLACK, Ohio residents ("LANDLORD") and MPW INDUSTRIAL SERVICES, INC., an Ohio
corporation ("TENANT").


                                   WITNESSETH:
                                   -----------


         1. DEMISED PREMISES: Landlord for and in consideration of the covenants
and agreements hereinafter set forth and the "RENT" (which term includes both
Base Rent and all Additional Rent) does hereby lease to Tenant not less than
100% of that certain approximately 45.88 acre tract of land (the legal
description of which is set forth on EXHIBIT "A-1" attached hereto (the "LAND"),
together with all improvements and fixtures located thereon including an
approximately 67,000 square foot office/industrial facility (collectively, the
"BUILDING") (all as more particularly described on the attached EXHIBIT "A-2"),
commonly known as 9711 Lancaster Road, SE, Village of Hebron, Licking County,
Ohio (the Building and the Land are sometimes hereinafter referred to
collectively as the "PREMISES").

         2. TERM:

            (a) INITIAL TERM. This Lease has an initial term of eighty-five (85)
months (or until such term shall sooner terminate as hereinafter provided) (the
"INITIAL TERM") commencing on December, 1, 1997 (the "COMMENCEMENT DATE") and
ending on December 31, 2004, unless sooner terminated in accordance herewith.

            (b) RENEWAL TERM. Tenant may, at its sole option, choose to extend
the term of this Lease for two (2) additional periods of five (5) years each (a
"RENEWAL TERM") under such terms and conditions as Landlord and Tenant will
negotiate, based upon a fair market appraisal of the Premises. Tenant shall
provide Landlord with written notice of Tenant's intent to exercise this option
not later than one hundred eighty (180) days prior to the expiration of the
Initial Term or first Renewal Term, as applicable. As used in this Lease, "TERM"
means both the Initial Term and, if Tenant exercises its option(s), any Renewal
Term. As used in this Lease, "LEASE YEAR" means each consecutive twelve (12)
month period of the Term, starting on the Commencement Date of this Lease.

         3. RENT:

            (a) Tenant shall pay as "BASE RENT" for each Lease Year during the
Initial Term the sum of Six Hundred Thousand and No/100 Dollars ($600,000),
payable in advance, in equal monthly installments of Fifty Thousand and No/100
Dollars ($50,000). If Tenant exercises its option(s) to extend the Term, Tenant
shall pay as Base Rent during the Renewal Term(s) a rental based upon the
"market rate" for the Premises. The first and last monthly installments are due
and payable on the execution of this Lease and the remaining installments are
due and payable in advance on the first day of each and every month during the
Term, without offset or deduction, to Landlord at the address set forth in
PARAGRAPH 26 or at such other place as Landlord may hereafter designate in
writing. Rent checks are to be made payable to Landlord, or such other person,
firm or corporation as Landlord may designate in writing.

            (b) All sums due and payable by Tenant under this Lease other than
Base Rent are "ADDITIONAL RENT", whether or not so called in the text of this
Lease. Any Additional Rent for which no time for payment is specified in this
Lease shall be due and payable within ten (10) days after demand is made
therefor.

            (c) All Rent, whether Base Rent or Additional Rent, is due and
payable in full without demand, deduction or set-off and Tenant's obligation to
pay the same shall survive the expiration or other termination of this Lease.
Tenant's covenant to pay Rent is an independent covenant.

            (d) Rent shall be equitably pro rated for any partial Lease Year or
calendar year, as the case may be, during the Term.

            (e) For each Renewal Term, Tenant shall notify Landlord that Tenant
desires to exercise its option to extend the Term of this Lease for the next
ensuing five (5) year period, and to obtain an appraisal of the Premises to
determine the market rent for the Premises by delivering written notice to
Landlord not less than one hundred twenty (120) days prior to the beginning of
each Renewal Term. Tenant shall include in such notice the name of an MAI
appraiser selected by Tenant which has an office in Licking County, Ohio.
Landlord shall within thirty (30) days following receipt of such notice from
Tenant give written notice to Tenant setting forth the name of a second MAI
appraiser with an office in Licking County, Ohio. If Landlord fails to notify
Tenant of the name of an appraiser within the thirty (30) day period, then the
appraiser selected by Tenant shall determine the market rent and the decision of
said appraiser shall be binding upon the parties hereto. If Landlord has
selected an appraiser in accordance with the provisions of this Paragraph, then
the appraiser selected by Landlord and the appraiser selected by Tenant shall
meet and select a third MAI appraiser with an office in Licking County, Ohio.
The appraiser selected by Landlord and the appraiser selected by Tenant shall
each appraise the Premises for purposes of obtaining said market rent. The third
appraiser shall determine and notify Landlord and Tenant which of the two
appraisals made by Landlord's and Tenant's appraisers more closely reflects the
market rent of the Premises, and the decision of the third appraiser shall be
binding upon the parties hereto. Notwithstanding anything in this paragraph to
the contrary, in no event shall the Base Rent for any Renewal Term be less than
the Base Rent for the previous Renewal Term or the Initial Term, as applicable.

         4. USE OF PREMISES:

            (a) PERMITTED USE. Tenant shall use and occupy the Premises solely
for operation of an industrial cleaning facility and related incidental uses
(including office and warehouse), in accordance with the standards of an
industrial facility in Union Township, Ohio, and for no other purpose
whatsoever.

            (b) COMPLIANCE WITH LAWS; NUISANCE. Tenant shall not use or permit
the Premises or any part thereof to be used for any disorderly, unlawful or
extra hazardous purpose nor for any purpose other than hereinbefore specified.
Tenant shall not act in conflict with the statutes, laws, ordinances, codes,
rules and regulations applicable to Tenant, the Premises and/or the Building,
including without limitation the rules, regulations and requirements of any fire
rating organizations or rating bureaus with jurisdiction over the Premises
(collectively, the "LEGAL REQUIREMENTS"). Tenant shall be responsible at its own
cost for complying with the provisions of the Americans With Disabilities Act or
any similar federal or Ohio statute, law, ordinance, or code, as they may be
amended from time to time, and the rules and regulations which may be adopted
thereunder from time to time, as the same may be applicable to Tenant's own use
of the Premises or as may be necessary or appropriate as the result of any
Alteration (as defined in PARAGRAPH 8). Landlord's approval of any Alteration or
other act by Tenant is not a representation by Landlord that said Alteration or
act complies with applicable law, and Tenant shall remain solely responsible for
such compliance. Notwithstanding the expiration or other termination of this
Lease, Tenant shall defend, indemnify and hold Landlord and Landlord's
mortgagees harmless from and against any claim, demand, suit, action,
proceeding, damage, liability, loss, cost or expense (including, without
limitation, reasonable attorneys' fees), foreseen or unforeseen, arising from
any violation of this PARAGRAPH 4; the provisions of this sentence shall survive
the expiration or other termination of this Lease.

            (c) HAZARDOUS SUBSTANCES. Tenant shall not (either with or without
negligence) cause or permit within or on the Premises the escape, disposal or
release of any biologically- or chemically-active or other hazardous or toxic
substances, materials or wastes (collectively, "HAZARDOUS SUBSTANCES"). Tenant
shall not allow the generation, storage or use of any Hazardous Substances
within the Premises in any manner other than normal quantities of cleaning
solvents controlled and stored in accordance with the Legal Requirements, unless
such Hazardous Substances are generated, stored or used in accordance with the
Legal Requirements and approved in advance in writing by Landlord. Any use of
Hazardous Substances shall only be in the ordinary course of Tenant's business
and in accordance with the highest standards prevailing in the industry for the
generation, storage and use of such Hazardous Substances. Without limitation,
Hazardous Substances shall include those described in the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, 42
U.S.C. Section 9601 ET SEQ., any applicable state or local laws and the
regulations adopted under these acts. If Tenant uses Hazardous Substances within
the Premises and if Landlord or any lender or governmental agency requires
testing to ascertain whether or not there has been any release of Hazardous
Substances, then the reasonable costs thereof shall be reimbursed by Tenant to
Landlord upon demand as Additional Rent. In addition, Tenant shall execute
affidavits, representations and the like from time to time at Landlord's request
concerning Tenant's best knowledge and belief regarding the presence of
Hazardous Substances in the Premises. Further, Tenant shall indemnify and save
Landlord harmless from and against any and all clean-up costs, remedial or
restoration work, claims, judgments, damages, penalties, fines, costs,
liabilities or losses, including, without limitation, attorneys', consultants'
and experts' fees, which arise during or after the Term as a result of any
Hazardous Substances being generated, used or disposed of in or on, or brought
to, the Premises by Tenant or its employees, agents, contractors or invitees, or
as the result of an abatement, treatment or management required as the result of
any acts, negligence, repairs or alterations made by Tenant in the Premises. The
within covenants shall survive the expiration or earlier termination of this
Lease.

         5. TAXES, FEES AND CHARGES: Tenant shall pay directly to the applicable
taxing authorities, at its sole cost and expense, and prior to delinquency, all
taxes, fees, assessments, and charges, general and special, foreseen or
unforeseen, affecting the Building, Premises or Tenant's other property or
operations thereon (the "TAXES"), including, without limitation, the payment for
any governmental licenses, permits, approvals, and authorizations attributable
to the Premises, the Building or any improvements thereto during the Term.
Tenant shall also pay any tax (other than Landlord's income tax) which may be
levied at any time on the Rent or other charges payable hereunder. Tenant shall
provide written proof of all such required payments to Landlord prior to the due
date thereof, and shall provide paid receipts therefor to Landlord upon request.
Tenant may contest any required payment of any of the Taxes by appropriate
proceedings duly instituted and diligently prosecuted at Tenant's expense,
provided that Tenant shall notify Landlord prior to the commencement of any such
contest. Landlord shall reasonably cooperate with Tenant (at Tenant's expense)
in connection with any such contest, and shall permit any such contest to be
prosecuted in Landlord's name if the same shall be required for the proper
resolution of the disputed matter. So long as any such contest is pending,
Tenant shall pay the disputed Taxes so that the Premises are not subjected to
loss or forfeiture as a result of nonpayment. Tenant shall indemnify, defend,
and hold Landlord harmless from and against any loss or forfeiture of the
Premises and any fines, penalties or other charges arising out of any such
contest or the resolution thereof or arising out of Tenant's failure to pay any
amounts required to be paid by Tenant hereunder.

         6. INSURANCE:

            (a) Tenant shall not do or permit anything to be done on the
Premises or in the Building or bring or keep anything therein which shall in any
way increase the rate of fire or other insurance on the Building, or on the
property kept therein or conflict with any insurance policy upon the Building or
any part thereof, or with any statutes, rules or regulations enacted or
established by the appropriate governmental authorities.

            (b) Tenant shall carry such insurance as Landlord may reasonably
require from time to time, including (without limitation) personal property,
liability, plate glass, builder's risk (during any period when any construction
work is being done in the Premises), business interruption, and workers'
compensation insurance. Tenant shall also provide and maintain public
liability/general comprehensive insurance protecting and indemnifying Landlord
and Tenant against all claims for damages in amounts not less than $2,000,000
per occurrence, $2,000,000 bodily injury, and $1,000,000 property damage. All
insurance must be issued by companies and be in amounts satisfactory to Landlord
in its reasonable discretion, include waivers of subrogation, provide that it
may not be canceled except upon at least thirty (30) days written notice to
Landlord, and name Landlord, its asset and building manager(s), and any
mortgagee or ground lessor of the Building as an additional named insured or
loss payee, as appropriate. Evidence of such insurance must be delivered to
Landlord before Tenant may enter the Premises and must be provided not less
frequently than the first day of each Lease Year thereafter.

            (c) At all times during the Term, Tenant shall, at Tenant's sole
cost and expense, maintain fire and extended coverage insurance covering the
Building to its full replacement value and with such co-insurance and deductible
provisions as may reasonably be deemed

<PAGE>   3


                                       -3-



appropriate by Landlord. Subject to the rights of any Landlord's mortgagee under
PARAGRAPH 18, below, all insurance proceeds under such policy shall be payable
to Tenant solely for the purpose of completing the restoration required under
PARAGRAPH 12, and Landlord shall be entitled to receive any proceeds remaining
following the completion of such restoration; if not so restored such insurance
proceeds shall be paid to Landlord.

            (d) Landlord shall maintain comprehensive general liability
insurance in amounts of at least $1,000,000 per occurrence, $500,000 property
damage, for losses occasioned by Landlord's and its representatives', agents'
and employees' negligence or willful misconduct.

            (e) No indemnity shall be paid to the other party under this Lease
where the claim, damage, liability, loss or expense incurred was or was required
to be insured by such other party for whose benefit such indemnity would run. If
reasonably available, all insurance policies obtained by the parties pursuant to
this Lease shall contain provisions or have the effect of waiving any right of
subrogation by the insurer of one party against the other party or its insurer.
Each party hereby releases the other from any claims to the extent covered by
insurance obtained by the parties pursuant to this Lease.

         7. UPKEEP OF PREMISES: Tenant shall keep the Premises and the fixtures
therein in good order and condition and will, at the expiration or other
termination of the Term, surrender and deliver up the same in like good order
and condition as the same now is or shall be at the commencement of the Term,
ordinary wear and tear and insured damage excepted. Subject to the provisions of
PARAGRAPHS 8 and 15 below, Landlord is not required to make any improvements,
replacements or repairs of any kind or character on the Premises during the
Term.

         8. ALTERATIONS:

            (a) Except as set forth in this PARAGRAPH 8 or in PARAGRAPH 12,
Tenant shall not make any alterations, installations, changes, replacements,
additions, or improvements (structural or otherwise) (each an "ALTERATION") in
or to the Premises or any part thereof without the consent of Landlord;
PROVIDED, HOWEVER, that Landlord shall not unreasonably withhold, condition or
delay its consent to any of the same which do not affect the structural,
mechanical, electrical, hydraulic, plumbing, heating, ventilating or air
conditioning systems serving either the Building or the Premises. All
Alterations in the Premises (whether installed with or without Landlord's
consent), shall at the election of Landlord remain in the Premises and be
surrendered with the Premises at the expiration of this Lease without
disturbance, molestation or injury; FURTHER PROVIDED, HOWEVER, that any and all
manufacturing items or other items of Tenant's personalty shall remain Tenant's
property and shall be removed by Tenant upon the expiration or earlier
termination of the Term. Should Landlord elect that Alterations made by Tenant
in the Premises be removed upon expiration or termination of this Lease, Tenant
shall cause same to be removed and to repair any damage caused thereby and
restore the Premises at Tenant's sole cost and expense and Tenant shall
reimburse Landlord for the cost of such removal together with any and all
damages which Landlord may suffer and sustain by reason of the failure of Tenant
to remove the same and to repair and restore as set forth above. Tenant shall
similarly restore any damage resulting from its removal of its personal
property.

            (b) Landlord is delivering the Premises to Tenant in their "AS IS"
condition, without any representation or warranty of any kind, express or
implied, as to their condition and without any obligation to perform any work or
to pay for any third party or Tenant to perform any work. By its execution of
this Lease, Tenant acknowledges that it has inspected Building and the Land and
that they are in condition satisfactory to Tenant.

            (c) All of Tenant's work shall be done by contractors acceptable to
Landlord in its reasonable discretion. Alterations by Tenant, including any
initial build-out, shall be coordinated with any work being performed by
Landlord. As further conditions to Landlord's approval of any proposed
Alterations or additions by Tenant which are to be made by a contractor, Tenant
shall cause the contractor(s) and subcontractor(s) to carry workmen's
compensation insurance in statutory amounts, builder's risk insurance and
comprehensive public liability insurance with limits as approved by Landlord,
and Tenant shall deliver to Landlord certificates of all such insurance.
Tenant's work shall be performed in a first-class and lien-free manner. Tenant
shall not be Landlord's agent for purposes of this work and Tenant shall be
solely responsible for any mechanics' or materialmen's lien arising therefrom;
Tenant shall pay, bond or otherwise release of record any such lien within ten
(10) days after receiving notice of its existence.

            (d) Tenant shall promptly pay for any work done or material
furnished in or about the Premises and shall not permit or suffer any lien to
attach to the Premises, and Tenant shall indemnify and save Landlord harmless
from and against any loss, liability, cost, or expense which may be incurred by
Landlord with respect to any such lien or claim of lien. Tenant shall promptly
cause any such liens which have arisen by reason of any work claimed to have
been undertaken by or through Tenant to be released by payment, bond or
otherwise within thirty (30) days after request by Landlord. Tenant shall have
no authority or power, express or implied, to create or cause any lien, charge,
or encumbrance of any kind against the Premises or the Building. Tenant shall
notify all of its contractors and materialmen in writing that any liens relating
to any work ordered by Tenant shall attach to Tenant's leasehold estate in the
Premises and shall not encumber Landlord's interest in the Premises or the
Building.

         9. SUBLETTING AND ASSIGNMENT: Tenant shall not sublet the Premises or
any part thereof or transfer possession or occupancy thereof to any person, firm
or corporation, or transfer or assign this Lease, nor will any assignment or
subletting hereof be effected by operation of law or otherwise, without
Landlord's prior consent, such consent not to be unreasonably withheld, delayed
or conditioned. A sale or other conveyance of any sort of all or substantially
all of the assets of Tenant relating to the Premises, or of a sufficient amount
of the stock or other ownership interests in Tenant to constitute a change in
control, or of any general partnership interest in Tenant if Tenant is a
partnership, whether directly or indirectly, constitutes an assignment under
this Paragraph. If Tenant desires to sublet the Premises or if Tenant desires to
transfer or assign this Lease, Tenant shall give Landlord thirty (30) days
written notice of Tenant's intention so to do. In no event whatsoever, and
without limiting Landlord's right to reasonably reject any proposed sublease or
assignment, may this Lease be assigned in part or the Premises subleased in
part, without Landlord's prior written reasonable consent.

         10. TENANT'S COVENANTS: Tenant further agrees: that no sign,
advertisement or notice shall be inscribed, painted or affixed on any part of
the outside or inside the Premises or Building except as may be expressly
permitted by this Lease, and then only in such size, color and style as Landlord
may reasonably approve; that Landlord shall have the right to prescribe the
weight and method of installation and position of safes or other heavy fixtures
or equipment and Tenant shall not install in the Premises any fixtures,
equipment or machinery that will place a load upon any floor exceeding the floor
load per square foot area which such floor was designed to carry; and that all
damages done to the Building by taking in or removing a safe or any other
article of Tenant's equipment, or due to Tenant's being in the Premises, shall
be repaired at the expense of Tenant.

                                       -4-



         11. ACCESS: Tenant further agrees that it will allow Landlord, its
agent or employees, or any mortgagee to enter the Premises at all reasonable
times: to examine, inspect or to protect the same or prevent damage or injury to
the same, or to make such alterations and repairs to the Premises or other
premises as Landlord may deem necessary; to exhibit the same to prospective
tenants during the last nine (9) months of the Term or following the
commencement of any action to evict Tenant, even if the Term has not been
terminated; and to exhibit the same to prospective and actual mortgagees,
purchasers and brokers at any time during the Term.

         12. DAMAGE:

             (a) In the event of damage to or destruction of the Premises, the
Building, or Tenant's other Alterations, or any portion thereof, during the Term
by fire, explosion or other casualty ("Damage"), this Lease will not terminate
unless Landlord determines that it will take Landlord more than ninety (90) days
to repair and restore the Premises to the same condition they are in on the date
hereof, in which event Landlord may terminate this Lease by notice to Tenant.

             (b) Unless this Lease is terminated pursuant to PARAGRAPH 12(A),
and except as expressly provided to the contrary in this Lease, in the event of
any Damage to the Premises: (i) this Lease shall remain in full force and effect
and to the extent possible, Tenant shall remain in possession of the Premises,
and (ii) whether or not any insurance proceeds are available or adequate for
such purposes and regardless of the dollar amount of such damage or loss, at
Tenant's own sole cost and expense, Tenant shall repair, refixture, restock and
otherwise restore the Premises to the same condition they were in before such
fire or other casualty. Due allowance, however, shall be given for a reasonable
time required for adjustment and settlement of insurance claims and for such
other delays as may result from government restrictions and controls on
construction, if any, and for strikes, national emergencies, and other
conditions beyond the control of the parties. (c) Any restoration required to be
performed by Tenant under this PARAGRAPH 12 shall be commenced by Tenant
promptly after such damage or destruction, and shall be diligently and
continuously pursued to completion and shall be completed by Tenant in a good
and workmanlike manner and in accordance with all Legal Requirements.

             (d) Tenant shall have no right to terminate this Lease or to have
the rent and other charges due hereunder abated despite the occurrence of Damage
to the Premises, the Building or Tenant's other Alterations, even if such Damage
prevents the conduct of Tenant's business on the Premises. No compensation,
claim, or diminution of Rent will be allowed or paid by Landlord by reason of
inconvenience, annoyance, or injury to business arising from any such Damage or
the necessity of repairing the Premises or the Building, however the necessity
may occur.

         13. PERSONAL PROPERTY: All personal property of Tenant at the Premises
is at the sole risk of Tenant. Landlord is not liable for any accident or
damages to property of Tenant resulting from the use or operation of elevators
or of the heating, cooling, electrical, mechanical, hydraulic, plumbing or other
Building systems or components. Landlord is not, in any event, liable for
damages to property resulting from water, steam, or other causes. Tenant hereby
expressly releases Landlord from any liability incurred or claimed by reason of
damage to Tenant's property. Landlord is not liable in damages, nor is this
Lease affected, for conditions arising or resulting from construction of
contiguous premises. The foregoing does not exculpate Landlord from its gross
negligence or willful misconduct.

         14. LIABILITY FOR TENANT'S OPERATIONS; INDEMNIFICATION:

             (a) Landlord assumes no liability or responsibility whatsoever with
respect to the conduct and operation of the business to be conducted in the
Premises. Landlord shall not be liable for any accident or injury to any person
or persons or property in or about the Premises which are caused by the conduct
and operation of said business or by virtue of equipment or property of Tenant
in the Premises. Tenant agrees to defend, indemnify and hold Landlord and
Landlord's mortgagees harmless from and against all such claims (including,
without limitation, reasonable attorneys' fees). The foregoing does not
exculpate Landlord from its gross negligence or willful misconduct.

             (b) Tenant retains responsibility as operator of the Premises for
payment of all costs of the Premises, and shall defend, indemnify and hold
Landlord harmless therefrom, and from all costs incurred by Landlord in the
defense of any claims relating to the Premises brought against it or any action
relating to the Premises in which it is named as a party, including reasonable
attorneys' fees, costs of investigation, court costs and other such expenses.
This indemnification obligation shall survive termination of this Lease, and is
subject to the waiver of subrogation provisions of PARAGRAPH 6(e); PROVIDED,
HOWEVER, notwithstanding anything contained herein to the contrary, Landlord
shall indemnify Tenant and hold Tenant and its affiliates and their respective
representatives, agents and employees harmless in connection with damage or loss
sustained by reason of the dishonesty, willful misconduct or negligence of
Landlord and its representatives, agents or employees.

         15. SERVICES AND UTILITIES:

             (a) Landlord shall provide the normal utility service connections
into the Premises. Tenant shall pay the cost of all utility service, including,
without limitation, initial connection charges, all charges for gas, water and
electricity used on the Premises, and for all plumbing, interior
cleaning/janitorial, and for all electric light lamps or tubes. Tenant shall pay
all costs caused by Tenant introducing excess pollutants into the sanitary sewer
system.

             (b) Any failure by Landlord to furnish any services or utilities to
be provided by Landlord or otherwise under this Lease as the result of any act
of God, FORCE MAJEURE or any cause beyond the reasonable control of Landlord
will not render Landlord liable in any respect for damages to either person or
property, nor be construed as an eviction of Tenant, nor work an abatement of
Rent, nor relieve Tenant from Tenant's obligations hereunder.

         16. BANKRUPTCY: If Tenant makes an assignment of its assets for the
benefit of creditors, or if Tenant files a voluntary petition in bankruptcy, or
if an involuntary petition in bankruptcy or for receivership is instituted
against Tenant and the same is not dismissed within ninety (90) days of the
filing thereof, or if Tenant is adjudged bankrupt, then and in any of the
foregoing events, to the extent permitted by law, this Lease will immediately
cease and terminate at the option of Landlord with the same force and effect as
though the date of said event was the day herein fixed for expiration of the
Term.

         17. DEFAULTS & REMEDIES: If Tenant fails to pay the Rent, or any
installment thereof, within five (5) days after the same becomes due and
payable, or if Tenant violates or fails or neglects to keep and perform any of
the covenants, conditions, and agreements herein contained on the part of Tenant
to be kept and performed within thirty (30) days after receipt of written notice
of such failure or neglect, or if the Premises becomes vacant or deserted, then,
and in each and every such event, at the option of Landlord, Tenant's right of
possession will thereupon cease and terminate, and to the extent permitted by
law Landlord will be entitled to the possession of the Premises and to re-enter
the same without demand of Rent or demand of possession and may forthwith
proceed to recover possession of the Premises by process of law, ANY NOTICE TO
QUIT OR OF INTENTION TO RE-ENTER THE SAME BEING HEREBY EXPRESSLY WAIVED BY
TENANT. In the event of such re-entry by process of law or otherwise, Tenant
nevertheless agrees to remain answerable for any and all damage, deficiency or
loss of Rent which Landlord may sustain by such re-entry, including reasonable
attorneys' fees and court costs; and in such case, Landlord reserves full power,
which is hereby acceded to by Tenant, to relet the Premises for the benefit of
Tenant, in liquidation and discharge, in whole or in part, as the case may be,
of the liability of Tenant under the terms and provision of this Lease. In
addition to the foregoing remedies, Landlord will also have the following
remedies to the extent permitted by law and all other remedies afforded to it at
law or in equity, all of which shall be cumulative: to terminate this Lease; to
declare due and payable all Rent for the unexpired Term as and when the same
becomes due and payable or to defer any suit until after the Term without
thereby prejudicing its rights; to accelerate the Rent for the remainder of the
Term and declare it all immediately due and payable [with a present value
discount two (2) whole percentage points below the prime rate published in The
Wall Street Journal on the date Landlord elects said remedy]; and to bring an
action for specific performance, injunction, or other equitable relief to
prevent any threatened or impending default or to end any existing default. In
addition, Landlord may perform any obligation which Tenant has failed to perform
after the expiration of any applicable notice and/or cure period (except in an
emergency, when no notice or cure period will be necessary or afforded), all at
the cost of Tenant as Additional Rent payable upon demand. Tenant shall also pay
all expenses (including, without limitation, reasonable attorneys' fees)
incurred by Landlord following a default, whether or not suit is instituted; the
same shall be Additional Rent payable upon demand. In determining the Rent due
for the balance of the Term, all Additional Rent shall be determined by
projecting into the future the Additional Rent payable on the date of default
increasing by a compounding five percent (5%) per Lease Year. No waiver of any
breach of any covenant, condition, or agreement herein contained shall operate
as a waiver of the covenant, condition or agreement itself, or of any subsequent
breach thereof. No provision of this Lease shall be deemed to have been waived
by Landlord unless such waiver shall be in writing signed by Landlord. No
payment by Tenant or receipt by Landlord of a lesser amount than the Rent herein
stipulated shall be deemed to be other than on account of the earliest
stipulated Rent, nor shall any endorsement or statement on any check or any
letter accompanying any check or payment as Rent be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of such Rent or pursue any other remedy
provided in this Lease. Landlord shall have a lien for the payment of the Rent
upon all of the goods, wares, chattels, fixtures, furniture and other personal
property of Tenant which may be in or upon the Premises, Tenant hereby
specifically waiving any and all exemptions allowed by law; such lien may be
enforced on the nonpayment of any installment of Rent by the taking and selling
of such property in the same manner as in the case of chattel mortgages on
default thereunder; said sale is to made upon ten (10) days notice served upon
Tenant by posting upon the Premises or such lien may be enforced in any other
lawful manner at the option of Landlord.

         18. RIGHTS OF LENDERS, GROUND LESSORS AND PURCHASERS: This Lease is
subject and subordinate to all ground or underlying leases (hereinafter
collectively referred to as "GROUND LEASES") and to all of the terms and
provisions and liens of all mortgages and/or deeds of trust (hereinafter
collectively referred to as "MORTGAGES") which may now or hereafter affect this
Lease or the Building, and to all renewals, modifications, consolidations,
replacements, amendments and extensions thereof. This clause is self-operative,
and no lessor or mortgagee (as used in this Lease, "MORTGAGEE" includes any
mortgagee under a mortgage, any beneficiary or trustee under a deed of trust,
and any lender or other secured party under a deed to secure debt or other
instrument similar to any of the foregoing) may require any instrument of
subordination. In confirmation of such subordination, Tenant shall execute
promptly any certificate that Landlord may request. Tenant hereby constitutes
and appoints Landlord Tenant's attorney-in-fact to execute any such certificate
or certificates for and on behalf of Tenant. Notwithstanding the foregoing, a
ground lessor or mortgagee may recognize this Lease and, in the event of the
termination of any ground lease or any foreclosure or similar sale or deed in
lieu thereof under such mortgage, this Lease will continue in full force and
effect at the option of the ground lessor or mortgagee (or the purchaser at any
such foreclosure sale). Tenant will, at the written request of the ground lessor
or mortgagee (or the purchaser at any such foreclosure sale), execute,
acknowledge and deliver any instrument that has for its purpose and effect the
subordination of such ground lease or mortgage to this Lease. In any case, such
ground lessor, mortgagee, landlord or successor shall not be bound by any
prepayment on the part of Tenant of any Rent for more than one month in advance,
so that Rent shall be payable under this Lease in accordance with its terms as
if such prepayment had not been made; nor shall any such ground lessor,
mortgagee, landlord or successor be liable for any default under this Lease by
any predecessor Landlord or subject to any counterclaim, set-off or defense as a
result of any such default; and provided, further, such ground lessor,
mortgagee, landlord or successor shall not be bound by this Lease or any
amendment or modification of this Lease unless Landlord's ground lessor or
mortgagee, as may be applicable, had approved the same in writing. At any time
and from time to time, upon the request and at the sole option of any successor
to Landlord's interest, Tenant shall attorn to any successor to Landlord's
interest, whether such successor acquires its interest by voluntary conveyance,
foreclosure, deed in lieu of foreclosure, termination or expiration of a ground
lease, or any other method, and in that event this Lease shall continue as a
direct lease between Tenant and such landlord or its successor and the prior
Landlord shall be released from all obligations and liability under this Lease
arising after the date of transfer. The terms of this Lease are subject to
approval by the Landlord's ground lessor(s) and lender(s), and such approval is
a condition precedent to Landlord's obligations hereunder. Tenant shall furnish
copies of any default or similar notices delivered by Tenant to Landlord
hereunder at the same time to each ground lessor or mortgagee, now or at anytime
and from time to time hereafter, and no such notice shall be effective unless
and until a copy of it is sent to each such ground lessor or mortgagee, provided
that Tenant has been afforded written notice of the name and address of such
party. Each such ground lessor or mortgagee may cure any default by Landlord
within the same time period afforded Landlord to cure any such default, plus
such additional period of time thereafter as may be reasonably necessary for
such ground lessor or mortgagee to cure such default.

         19. CONDEMNATION: If the Premises or any part thereof is taken or
condemned for public or quasi-public use or purpose by any competent authority,
or conveyed in lieu of being taken or condemned, Tenant will have no claim
against Landlord and will not have any claim or right to any portion of the
amount that may be awarded to Landlord as damages or paid as a result thereof.
All right of Tenant to damages therefor, if any, are hereby assigned by Tenant
to Landlord. Upon such condemnation or taking, or conveyance in lieu thereof,
the Term shall terminate from the date of such governmental taking or
condemnation, or conveyance in lieu thereof, and Tenant will have no claim
against Landlord for the value of any unexpired Term. Nothing in this Paragraph
limits or affects Tenant's right to seek any separate award from the condemning
authority as long as Tenant does not thereby reduce, delay or in any other way
affect Landlord's claim or award.

         20. SUCCESSORS: All rights, remedies and liabilities herein given to or
imposed upon either of the parties hereto extend to their respective heirs,
executors, administrators, successors and permitted assigns.

         21. TENANT HOLDOVER: If Tenant continues to remain in the Premises
after the termination or expiration of the Term, then Tenant will become a
tenant by the month at 125% of the Base Rent per month payable for the last
month before the expiration or termination of the Term plus all Additional Rent
that may be incurred during any such holdover, but in no event less than the
then market rent for the Premises. Holdover Rent will commence with the first
day following the end of the Term. During any holdover, each party must give the
other at least thirty (30) days written notice to quit the Premises, except in
the event of any default by Tenant, in which event Tenant will not be entitled
to any notice to quit, the usual thirty (30) days' notice to quit being hereby
expressly waived; PROVIDED, HOWEVER, that if Tenant holds over after the
expiration of the Term hereby created, and if Landlord desires to regain
possession of the Premises promptly at the expiration of the Term, then at any
time prior to Landlord's acceptance of Rent from Tenant as a monthly tenant
hereunder, Landlord, at its option, may forthwith re-enter and take possession
of the Premises without process, or by any legal process in force. Tenant shall
not use FORCE MAJEURE as an excuse for any holding over.

         22. POSSESSION: Landlord shall give possession of the Premises to
Tenant on the Commencement Date. If Landlord is unable to give possession of the
Premises on the Commencement Date because any portion of the Premises are
located in a Building being constructed that has not been sufficiently completed
to make the Premises ready for occupancy, or because a certificate of occupancy
has not been procured, or if Landlord is unable to give possession of the
Premises on the Commencement Date because of the holding over or retention of
possession by any previous tenant, occupant or owner, or if repairs,
improvements or decorations of the Premises or of the Building are not
completed, or for any other reason, Landlord will not be subject to any
liability for the failure to give possession on the Commencement Date. No such
failure to give possession on the Commencement Date will affect in any other
respect the validity of this Lease or the obligations of Tenant hereunder, nor
will the same be construed in any way to extend the Term. If Landlord permits
Tenant to enter into the possession of the Premises or a portion of the Premises
prior to the Commencement Date, such occupancy shall be deemed to be under all
terms, covenants, conditions and provisions of this Lease.

         23. JOINT AND SEVERAL LIABILITY: If Tenant consists of more than one
individuals and/or entities, then the liability of each of them for Tenant's
obligations under this Lease shall be joint and several.

         24. PRONOUNS: Feminine, masculine or neuter pronouns shall be
substituted for each other, and the plural shall be substituted for the singular
number and vice versa in any place in which the context may require such
substitution.

         25. LATE PAYMENT: If Tenant fails to pay any Rent on or before the
fifth (5th) day after such payment becomes due and payable, Tenant shall pay to
Landlord a late charge of five percent (5%) of the amount of such overdue
payment. In addition, any Rent not paid when due will bear interest at the
lesser of eighteen percent (18%) per annum or the maximum rate allowed by law
until paid. Acceptance of the foregoing sums shall not constitute a waiver of
the default. Upon Landlord's receipt of any check from Tenant which is
dishonored for payment, Landlord may require Tenant to make all future payments
due to Landlord hereunder by cash, certified or cashier's check.

         26. NOTICES: All notices required or desired to be given hereunder by
either party to the other shall be given by hand, by overnight courier or by
certified or registered mail. Notices shall be effective upon receipt (refusal
to accept delivery or the inability to make delivery due to an incorrect or
outdated address being provided by the intended recipient shall constitute
receipt). Notices to the respective parties must be addressed as follows:

         If to Landlord -           Monte R. Black
                                    9711 Lancaster Road, S.E.
                                    Hebron, Ohio  43025

         If to Tenant -             MPW Industrial Services, Inc.

                                    Attn:  Daniel P. Buettin

Either party may, by like written notice, designate a new address or addressee
to which notices must be directed. Tenant shall provide a copy of any notice
given to Landlord to any mortgagee or ground lessor of whom Tenant has notice.
Notices may be given by authorized agents or attorneys on behalf of a party.

         27. ESTOPPEL CERTIFICATES: Within ten (10) days after request therefor
by Landlord or any ground lessor or mortgagee of the Building, Tenant shall
execute and deliver estoppel certificates certifying, among other things: the
text of this Lease and any amendments thereto; whether this Lease has been
amended and, if so, the date of each such amendment; whether this Lease is in
full force and effect and, if not, the reason therefor; whether any default or
any situation which could be a default after the giving of notice or the
expiration of any cure period (or both) exists under this Lease on the part of
Landlord or Tenant and, if so, specifying the default or potential default;
whether Tenant has taken possession of the Premises; whether the Premises have
been completed in accordance with the terms of this Lease and all bills therefor
paid and, if not, what remains to be done or paid; the Commencement Date and the
expiration date of the Term; whether Tenant has any renewal options, expansion
options, or rights to purchase and, if so, identifying the conditions and
periods when they may be exercised; the date Rent commenced to accrue and the
date to which Rent has been paid; whether any security deposit has been posted;
whether Tenant has any knowledge or any environmental problem affecting the
Premises or the Building; and such other matters as may be reasonably requested.

         28. NO PERSONAL LIABILITY: Notwithstanding any provision of this Lease
to the contrary or any general rule of law, in no event whatsoever shall
Landlord or any of its shareholders, partners, directors, officers, employees,
agents or other principals have any personal liability whatsoever with respect
to this Lease, and no such personal liability shall be sought, obtained or
enforced. Any liability of Landlord under this Lease may be enforced solely
against Landlord's equity interest in the Land and Building; no other properties
or assets of Landlord are subject to this Lease or Landlord's liabilities
hereunder.

         29. BROKERS: Each party represents and warrants to the other that it
has not engaged or used any broker or finder in connection with this Lease. Each
party shall defend, indemnify and hold the other party harmless from and against
any breach by the indemnifying party of the representation and warranty set
forth in the first sentence of this Paragraph. Tenant shall defend, indemnify
and hold Landlord's ground lessors and mortgagees harmless from and against any
breach by Tenant of the representation and warranty set forth in the first
sentence of this Paragraph. No broker is a third party beneficiary of this
Lease.

         30. COMPLETE AGREEMENT; NO ORAL MODIFICATIONS: This Lease represents
the complete and integrated agreement of the parties with respect to the
Premises and, except as set forth herein, there are no other agreements,
covenants, representations or warranties (express or implied) between the
parties. Nothing in this Lease shall be deemed or construed to create a
partnership or joint venture or to create any relationship other than landlord
and tenant. This Lease may not be amended except by a written document signed by
the party to be bound thereby.

         31. GOVERNING LAW AND RULES OF INTERPRETATION: This Lease is governed
by the laws of the State of Ohio without regard to conflicts of laws. Without
limiting a party's right to bring any action in any other jurisdiction or forum,
each party submits itself to the jurisdiction of the federal and local courts
sitting in the State of Ohio and to venue therein. It is the intent of the
parties that this Lease will be enforceable to the fullest extent permitted by
law. If any provision of this Lease is capable of two or more interpretations or
can be reformed so as to comply with applicable law while giving effect to the
intent of such provision, then such provision shall be interpreted in the way
most likely to be in compliance with applicable law. Although the printed
provisions of this Lease were drawn by Landlord, this Lease shall not be
construed either for or against Landlord or Tenant.


         IN WITNESS WHEREOF, Landlord and Tenant have executed this Lease under
seal as of the day and year first above written.

                                      LEASE
                                      -----



         THIS LEASE ("LEASE"), is made this 11th day of February, 1998,
effective as of December 1, 1997, by and between MONTE R. BLACK AND SUSAN K.
BLACK, Ohio residents ("LANDLORD") and MPW INDUSTRIAL SERVICES, INC., an Ohio
corporation ("TENANT").


                                   WITNESSETH:
                                   -----------


         1. DEMISED PREMISES: Landlord for and in consideration of the covenants
and agreements hereinafter set forth and the "RENT" (which term includes both
Base Rent and all Additional Rent) does hereby lease to Tenant not less than
100% of that certain approximately .5903 acre tract of land (the legal
description of which is set forth on EXHIBIT "A-1" attached hereto (the "LAND"),
together with all improvements and fixtures located thereon including an
approximately 14,040 square foot industrial facility (collectively, the
"BUILDING") (all as more particularly described on the attached EXHIBIT "A-2"),
commonly known as 150 S. 28th Street, Newark, Licking County, Ohio (the Building
and the Land are sometimes hereinafter referred to collectively as the
"PREMISES").

         2. TERM:

            (a) INITIAL TERM. This Lease has an initial term of eighty-five (85)
months (or until such term shall sooner terminate as hereinafter provided) (the
"INITIAL TERM") commencing on December 1, 1997 (the "COMMENCEMENT DATE") and
ending on December 31, 2004, unless sooner terminated in accordance herewith.

            (b) RENEWAL TERM. Tenant may, at its sole option, choose to extend
the term of this Lease for two (2) additional periods of five (5) years each (a
"RENEWAL TERM") under such terms and conditions as Landlord and Tenant will
negotiate, based upon a fair market appraisal of the Premises. Tenant shall
provide Landlord with written notice of Tenant's intent to exercise this option
not later than one hundred eighty (180) days prior to the expiration of the
Initial Term or first Renewal Term, as applicable. As used in this Lease, "TERM"
means both the Initial Term and, if Tenant exercises its option(s), any Renewal
Term. As used in this Lease, "LEASE YEAR" means each consecutive twelve (12)
month period of the Term, starting on the Commencement Date of this Lease.

         3. RENT:

            (a) Tenant shall pay as "BASE RENT" for each Lease Year during the
Initial Term the sum of Sixty-Six Thousand and No/100 Dollars ($66,000.00),
payable in advance, in equal monthly installments of Five Thousand Five Hundred
and No/100 Dollars ($5,500.00). If Tenant exercises its option(s) to extend the
Term, Tenant shall pay as Base Rent during the Renewal Term(s) a rental based
upon the "market rate" for the Premises. The first and last monthly installments
are due and payable on the execution of this Lease and the remaining
installments are due and payable in advance on the first day of each and every
month during the Term, without offset or deduction, to Landlord at the address
set forth in PARAGRAPH 26 or at such other place as Landlord may hereafter
designate in writing. Rent checks are to be made payable to Landlord, or such
other person, firm or corporation as Landlord may designate in writing.

            (b) All sums due and payable by Tenant under this Lease other than
Base Rent are "ADDITIONAL RENT", whether or not so called in the text of this
Lease. Any Additional Rent for which no time for payment is specified in this
Lease shall be due and payable within ten (10) days after demand is made
therefor.

            (c) All Rent, whether Base Rent or Additional Rent, is due and
payable in full without demand, deduction or set-off and Tenant's obligation to
pay the same shall survive the expiration or other termination of this Lease.
Tenant's covenant to pay Rent is an independent covenant.

            (d) Rent shall be equitably pro rated for any partial Lease Year or
calendar year, as the case may be, during the Term.

            (e) For each Renewal Term, Tenant shall notify Landlord that Tenant
desires to exercise its option to extend the Term of this Lease for the next
ensuing five (5) year period, and to obtain an appraisal of the Premises to
determine the market rent for the Premises by delivering written notice to
Landlord not less than one hundred twenty (120) days prior to the beginning of
each Renewal Term. Tenant shall include in such notice the name of an MAI
appraiser selected by Tenant which has an office in Licking County, Ohio.
Landlord shall within thirty (30) days following receipt of such notice from
Tenant give written notice to Tenant setting forth the name of a second MAI
appraiser with an office in Licking County, Ohio. If Landlord fails to notify
Tenant of the name of an appraiser within the thirty (30) day period, then the
appraiser selected by Tenant shall determine the market rent and the decision of
said appraiser shall be binding upon the parties hereto. If Landlord has
selected an appraiser in accordance with the provisions of this Paragraph, then
the appraiser selected by Landlord and the appraiser selected by Tenant shall
meet and select a third MAI appraiser with an office in Licking County, Ohio.
The appraiser selected by Landlord and the appraiser selected by Tenant shall
each appraise the Premises for purposes of obtaining said market rent. The third
appraiser shall determine and notify Landlord and Tenant which of the two
appraisals made by Landlord's and Tenant's appraisers more closely reflects the
market rent of the Premises, and the decision of the third appraiser shall be
binding upon the parties hereto. Notwithstanding anything in this paragraph to
the contrary, in no event shall the Base Rent for any Renewal Term be less than
the Base Rent for the previous Renewal Term or the Initial Term, as applicable.

         4. USE OF PREMISES:

            (a) PERMITTED USE. Tenant shall use and occupy the Premises solely
for operation of an industrial water facility and related incidental uses
(INCLUDING OFFICE AND WAREHOUSE), in accordance with the standards of an
industrial facility in Union Township, Ohio, and for no other purpose
whatsoever.

            (b) COMPLIANCE WITH LAWS; NUISANCE. Tenant shall not use or permit
the Premises or any part thereof to be used for any disorderly, unlawful or
extra hazardous purpose nor for any purpose other than hereinbefore specified.
Tenant shall not act in conflict with the statutes, laws, ordinances, codes,
rules and regulations applicable to Tenant, the Premises and/or the Building,
including without limitation the rules, regulations and requirements of any fire
rating organizations or rating bureaus with jurisdiction over the Premises
(collectively, the "LEGAL REQUIREMENTS"). Tenant shall be responsible at its own
cost for complying with the provisions of the Americans With Disabilities Act or
any similar federal or Ohio statute, law, ordinance, or code, as they may be
amended from time to time, and the rules and regulations which may be adopted
thereunder from time to time, as the same may be applicable to Tenant's own use
of the Premises or as may be necessary or appropriate as the result of any
Alteration (as defined in PARAGRAPH 8). Landlord's approval of any Alteration or
other act by Tenant is not a representation by Landlord that said Alteration or
act complies with applicable law, and Tenant shall remain solely responsible for
such compliance. Notwithstanding the expiration or other termination of this
Lease, Tenant shall defend, indemnify and hold Landlord and Landlord's
mortgagees harmless from and against any claim, demand, suit, action,
proceeding, damage, liability, loss, cost or expense (including, without
limitation, reasonable attorneys' fees), foreseen or unforeseen, arising from
any violation of this PARAGRAPH 4; the provisions of this sentence shall survive
the expiration or other termination of this Lease.

            (c) HAZARDOUS SUBSTANCES. Tenant shall not (either with or without
negligence) cause or permit within or on the Premises the escape, disposal or
release of any biologically- or chemically-active or other hazardous or toxic
substances, materials or wastes (collectively, "HAZARDOUS SUBSTANCES"). Tenant
shall not allow the generation, storage or use of any Hazardous Substances
within the Premises in any manner other than normal quantities of cleaning
solvents controlled and stored in accordance with the Legal Requirements, unless
such Hazardous Substances are generated, stored or used in accordance with the
Legal Requirements and approved in advance in writing by Landlord. Any use of
Hazardous Substances shall only be in the ordinary course of Tenant's business
and in accordance with the highest standards prevailing in the industry for the
generation, storage and use of such Hazardous Substances. Without limitation,
Hazardous Substances shall include those described in the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, 42
U.S.C. Section 9601 ET SEQ., any applicable state or local laws and the
regulations adopted under these acts. If Tenant uses Hazardous Substances within
the Premises and if Landlord or any lender or governmental agency requires
testing to ascertain whether or not there has been any release of Hazardous
Substances, then the reasonable costs thereof shall be reimbursed by Tenant to
Landlord upon demand as Additional Rent. In addition, Tenant shall execute
affidavits, representations and the like from time to time at Landlord's request
concerning Tenant's best knowledge and belief regarding the presence of
Hazardous Substances in the Premises. Further, Tenant shall indemnify and save
Landlord harmless from and against any and all clean-up costs, remedial or
restoration work, claims, judgments, damages, penalties, fines, costs,
liabilities or losses, including, without limitation, attorneys', consultants'
and experts' fees, which arise during or after the Term as a result of any
Hazardous Substances being generated, used or disposed of in or on, or brought
to, the Premises by Tenant or its employees, agents, contractors or invitees, or
as the result of an abatement, treatment or management required as the result of
any acts, negligence, repairs or alterations made by Tenant in the Premises. The
within covenants shall survive the expiration or earlier termination of this
Lease.

         5. TAXES, FEES AND CHARGES: Tenant shall pay directly to the
applicable taxing authorities, at its sole cost and expense, and prior to
delinquency, all taxes, fees, assessments, and charges, general and special,
foreseen or unforeseen, affecting the Building, Premises or Tenant's other
property or operations thereon (the "TAXES"), including, without limitation, the
payment for any governmental licenses, permits, approvals, and authorizations
attributable to the Premises, the Building or any improvements thereto during
the Term. Tenant shall also pay any tax (other than Landlord's income tax) which
may be levied at any time on the Rent or other charges payable hereunder. Tenant
shall provide written proof of all such required payments to Landlord prior to
the due date thereof, and shall provide paid receipts therefor to Landlord upon
request. Tenant may contest any required payment of any of the Taxes by
appropriate proceedings duly instituted and diligently prosecuted at Tenant's
expense, provided that Tenant shall notify Landlord prior to the commencement of
any such contest. Landlord shall reasonably cooperate with Tenant (at Tenant's
expense) in connection with any such contest, and shall permit any such contest
to be prosecuted in Landlord's name if the same shall be required for the proper
resolution of the disputed matter. So long as any such contest is pending,
Tenant shall pay the disputed Taxes so that the Premises are not subjected to
loss or forfeiture as a result of nonpayment. Tenant shall indemnify, defend,
and hold Landlord harmless from and against any loss or forfeiture of the
Premises and any fines, penalties or other charges arising out of any such
contest or the resolution thereof or arising out of Tenant's failure to pay any
amounts required to be paid by Tenant hereunder.

         6. INSURANCE:

            (a) Tenant shall not do or permit anything to be done on the
Premises or in the Building or bring or keep anything therein which shall in any
way increase the rate of fire or other insurance on the Building, or on the
property kept therein or conflict with any insurance policy upon the Building or
any part thereof, or with any statutes, rules or regulations enacted or
established by the appropriate governmental authorities.

            (b) Tenant shall carry such insurance as Landlord may reasonably
require from time to time, including (without limitation) personal property,
liability, plate glass, builder's risk (during any period when any construction
work is being done in the Premises), business interruption, and workers'
compensation insurance. Tenant shall also provide and maintain public
liability/general comprehensive insurance protecting and indemnifying Landlord
and Tenant against all claims for damages in amounts not less than $2,000,000
per occurrence, $2,000,000 bodily injury, and $1,000,000 property damage. All
insurance must be issued by companies and be in amounts satisfactory to Landlord
in its reasonable discretion, include waivers of subrogation, provide that it
may not be canceled except upon at least thirty (30) days written notice to
Landlord, and name Landlord, its asset and building manager(s), and any
mortgagee or ground lessor of the Building as an additional named insured or
loss payee, as appropriate. Evidence of such insurance must be delivered to
Landlord before Tenant may enter the Premises and must be provided not less
frequently than the first day of each Lease Year thereafter.

                                       -3-



            (c) At all times during the Term, Tenant shall, at Tenant's sole
cost and expense, maintain fire and extended coverage insurance covering the
Building to its full replacement value and with such co-insurance and deductible
provisions as may reasonably be deemed appropriate by Landlord. Subject to the
rights of any Landlord's mortgagee under PARAGRAPH 18, below, all insurance
proceeds under such policy shall be payable to Tenant solely for the purpose of
completing the restoration required under PARAGRAPH 12, and Landlord shall be
entitled to receive any proceeds remaining following the completion of such
restoration; if not so restored, such insurance proceeds on the Building shall
be paid to Landlord.

            (d) Landlord shall maintain comprehensive general liability
insurance in amounts of at least $1,000,000 per occurrence, $500,000 property
damage, for losses occasioned by Landlord's and its representatives', agents'
and employees' negligence or willful misconduct.

            (e) No indemnity shall be paid to the other party under this Lease
where the claim, damage, liability, loss or expense incurred was or was required
to be insured by such other party for whose benefit such indemnity would run. If
reasonably available, all insurance policies obtained by the parties pursuant to
this Lease shall contain provisions or have the effect of waiving any right of
subrogation by the insurer of one party against the other party or its insurer.
Each party hereby releases the other from any claims to the extent covered by
insurance obtained by the parties pursuant to this Lease.

         7. UPKEEP OF PREMISES: Tenant shall keep the Premises and the fixtures
therein in good order and condition and will, at the expiration or other
termination of the Term, surrender and deliver up the same in like good order
and condition as the same now is or shall be at the commencement of the Term,
ordinary wear and tear and insured damage excepted. Subject to the provisions of
PARAGRAPHS 8 and 15 below, Landlord is not required to make any improvements,
replacements or repairs of any kind or character on the Premises during the
Term.

         8. ALTERATIONS:

            (a) Except as set forth in this PARAGRAPH 8 or in PARAGRAPH 12,
Tenant shall not make any alterations, installations, changes, replacements,
additions, or improvements (structural or otherwise) (each an "ALTERATION") in
or to the Premises or any part thereof without the consent of the Landlord;
PROVIDED, HOWEVER, that Landlord shall not unreasonably withhold, condition or
delay its consent to any of the same which do not affect the structural,
mechanical, electrical, hydraulic, plumbing, heating, ventilating or air
conditioning systems serving either the Building or the Premises. All
Alterations in the Premises (whether installed with or without Landlord's
consent), shall at the election of Landlord remain in the Premises and be
surrendered with the Premises at the expiration of this Lease without
disturbance, molestation or injury; FURTHER PROVIDED, HOWEVER, that any and all
manufacturing items or other items of Tenant's personalty shall remain Tenant's
property and shall be removed by Tenant upon the expiration or earlier
termination of the Term. Should Landlord elect that Alterations made by Tenant
in the Premises be removed upon expiration or termination of this Lease, Tenant
shall cause same to be removed and to repair any damage caused thereby and
restore the Premises at Tenant's sole cost and expense and Tenant shall
reimburse Landlord for the cost of such removal together with any and all
damages which Landlord may suffer and sustain by reason of the failure of Tenant
to remove the same and to repair and restore as set forth above. Tenant shall
similarly restore any damage resulting from its removal of its personal
property.

            (b) Landlord is delivering the Premises to Tenant in their "AS IS"
condition, without any representation or warranty of any kind, express or
implied, as to their condition and without any obligation to perform any work or
to pay for any third party or Tenant to perform any work. By its execution of
this Lease, Tenant acknowledges that it has inspected Building and the Land and
that they are in condition satisfactory to Tenant.

            (c) All of Tenant's work shall be done by contractors acceptable to
Landlord in its reasonable discretion. Alterations by Tenant, including any
initial build-out, shall be coordinated with any work being performed by
Landlord. As further conditions to Landlord's approval of any proposed
Alterations or additions by Tenant which are to be made by a contractor, Tenant
shall cause the contractor(s) and subcontractor(s) to carry workmen's
compensation insurance in statutory amounts, builder's risk insurance and
comprehensive public liability insurance with limits as approved by Landlord,
and Tenant shall deliver to Landlord certificates of all such insurance.
Tenant's work shall be performed in a first-class and lien-free manner. Tenant
shall not be Landlord's agent for purposes of this work and Tenant shall be
solely responsible for any mechanics' or materialmen's lien arising therefrom;
Tenant shall pay, bond or otherwise release of record any such lien within ten
(10) days after receiving notice of its existence.

            (d) Tenant shall promptly pay for any work done or material
furnished in or about the Premises and shall not permit or suffer any lien to
attach to the Premises, and Tenant shall indemnify and save Landlord harmless
from and against any loss, liability, cost, or expense which may be incurred by
Landlord with respect to any such lien or claim of lien. Tenant shall promptly
cause any such liens which have arisen by reason of any work claimed to have
been undertaken by or through Tenant to be released by payment, bond or
otherwise within thirty (30) days after request by Landlord. Tenant shall have
no authority or power, express or implied, to create or cause any lien, charge,
or encumbrance of any kind against the Premises or the Building. Tenant shall
notify all of its contractors and materialmen in writing that any liens relating
to any work ordered by Tenant shall attach to Tenant's leasehold estate in the
Premises and shall not encumber Landlord's interest in the Premises or the
Building.

         9. SUBLETTING AND ASSIGNMENT: Tenant shall not sublet the Premises or
any part thereof or transfer possession or occupancy thereof to any person, firm
or corporation, or transfer or assign this Lease, nor will any assignment or
subletting hereof be effected by operation of law or otherwise, without
Landlord's prior consent, such consent not to be unreasonably withheld, delayed
or conditioned. A sale or other conveyance of any sort of all or substantially
all of the assets of Tenant relating to the Premises, or of a sufficient amount
of the stock or other ownership interests in Tenant to constitute a change in
control, or of any general partnership interest in Tenant if Tenant is a
partnership, whether directly or indirectly, constitutes an assignment under
this Paragraph. If Tenant desires to sublet the Premises or if Tenant desires to
transfer or assign this Lease, Tenant shall give Landlord thirty (30) days
written notice of Tenant's intention so to do. In no event whatsoever, and
without limiting Landlord's right to reasonably reject any proposed sublease or
assignment, may this Lease be assigned in part or the Premises subleased in
part, without Landlord's prior written reasonable consent.

         10. TENANT'S COVENANTS: Tenant further agrees: that no sign,
advertisement or notice shall be inscribed, painted or affixed on any part of
the outside or inside the Premises or Building except as may be expressly
permitted by this Lease, and then only in such size, color and style as Landlord
may reasonably approve; that Landlord shall have the right to prescribe the
weight and method of installation and position of safes or other






<PAGE>   4


                                       -4-



heavy fixtures or equipment and Tenant shall not install in the Premises any
fixtures, equipment or machinery that will place a load upon any floor exceeding
the floor load per square foot area which such floor was designed to carry; and
that all damages done to the Building by taking in or removing a safe or any
other article of Tenant's equipment, or due to Tenant's being in the Premises,
shall be repaired at the expense of Tenant.

         11. ACCESS: Tenant further agrees that it will allow Landlord, its
agent or employees, or any mortgagee to enter the Premises at all reasonable
times: to examine, inspect or to protect the same or prevent damage or injury to
the same, or to make such alterations and repairs to the Premises or other
premises as Landlord may deem necessary; to exhibit the same to prospective
tenants during the last nine (9) months of the Term or following the
commencement of any action to evict Tenant, even if the Term has not been
terminated; and to exhibit the same to prospective and actual mortgagees,
purchasers and brokers at any time during the Term.

         12. DAMAGE:

            (a) In the event of damage to or destruction of the Premises, the
Building, or Tenant's other alterations or improvements, or any portion thereof,
during the Term by fire, explosion or other casualty ("Damage"), this Lease will
not terminate unless Landlord determines that it will take Landlord more than
ninety (90) days to repair and restore the Premises to the same condition they
are in on the date hereof, in which event Landlord may terminate this Lease by
notice to Tenant.

            (b) Unless this Lease is terminated pursuant to PARAGRAPH 12(a), and
except as expressly provided to the contrary in this Lease, in the event of any
Damage to the Premises: (i) this Lease shall remain in full force and effect and
to the extent possible, Tenant shall remain in possession of the Premises, and
(ii) whether or not any insurance proceeds are available or adequate for such
purposes and regardless of the dollar amount of such damage or loss, at Tenant's
own sole cost and expense, Tenant shall repair, refixture, restock and otherwise
restore the Premises to the same condition they were in before such fire or
other casualty. Due allowance, however, shall be given for a reasonable time
required for adjustment and settlement of insurance claims and for such other
delays as may result from government restrictions and controls on construction,
if any, and for strikes, national emergencies, and other conditions beyond the
control of the parties.

            (c) Any restoration required to be performed by Tenant under this
PARAGRAPH 12 shall be commenced by Tenant promptly after such damage or
destruction, and shall be diligently and continuously pursued to completion and
shall be completed by Tenant in a good and workmanlike manner and in accordance
with all Legal Requirements.

            (d) Tenant shall have no right to terminate this Lease or to have
the rent and other charges due hereunder abated despite the occurrence of Damage
to the Premises, the Building or Tenant's other Alterations or improvements,
even if such Damage prevents the conduct of Tenant's business on the Premises.
No compensation, claim, or diminution of Rent will be allowed or paid by
Landlord by reason of inconvenience, annoyance, or injury to business arising
from any such Damage or the necessity of repairing the Premises or the Building,
however the necessity may occur.

         13. PERSONAL PROPERTY: All personal property of Tenant at the Premises
is at the sole risk of Tenant. Landlord is not liable for any accident or
damages to property of Tenant resulting from the use or operation of elevators
or of the heating, cooling, electrical, mechanical, hydraulic, plumbing or other
Building systems or components. Landlord is not, in any event, liable for
damages to property resulting from water, steam, or other causes. Tenant hereby
expressly releases Landlord from any liability incurred or claimed by reason of
damage to Tenant's property. Landlord is not liable in damages, nor is this
Lease affected, for conditions arising or resulting from construction of
contiguous premises. The foregoing does not exculpate Landlord from its gross
negligence or willful misconduct.

         14. LIABILITY FOR TENANT'S OPERATIONS; INDEMNIFICATION:

            (a) Landlord assumes no liability or responsibility whatsoever with
respect to the conduct and operation of the business to be conducted in the
Premises. Landlord shall not be liable for any accident or injury to any person
or persons or property in or about the Premises which are caused by the conduct
and operation of said business or by virtue of equipment or property of Tenant
in the Premises. Tenant agrees to defend, indemnify and hold Landlord and
Landlord's mortgagees harmless from and against all such claims (including,
without limitation, reasonable attorneys' fees). The foregoing does not
exculpate Landlord from its gross negligence or willful misconduct.

            (b) Tenant retains responsibility as operator of the Premises for
payment of all costs of the Premises, and shall defend, indemnify and hold
Landlord harmless therefrom, and from all costs incurred by Landlord in the
defense of any claims relating to the Premises brought against it or any action
relating to the Premises in which it is named as a party, including reasonable
attorneys' fees, costs of investigation, court costs and other such expenses.
This indemnification obligation shall survive termination of this Lease, and is
subject to the waiver of subrogation provisions of PARAGRAPH 6(e); PROVIDED,
HOWEVER, notwithstanding anything contained herein to the contrary, Landlord
shall indemnify Tenant and hold Tenant and its affiliates and their respective
representatives, agents and employees harmless in connection with damage or loss
sustained by reason of the dishonesty, willful misconduct or negligence of
Landlord and its representatives, agents or employees.

         15. SERVICES AND UTILITIES:

            (a) Landlord shall provide the normal utility service connections
into the Premises. Tenant shall pay the cost of all utility service, including,
without limitation, initial connection charges, all charges for gas, water and
electricity used on the Premises, and for all plumbing, interior
cleaning/janitorial, and for all electric light lamps or tubes. Tenant shall pay
all costs caused by Tenant introducing excess pollutants into the sanitary sewer
system.

            (b) Any failure by Landlord to furnish any services or utilities to
be provided by Landlord or otherwise under this Lease as the result of any act
of God, FORCE MAJEURE or any cause beyond the reasonable control of Landlord
will not render Landlord liable in any respect for damages to






<PAGE>   5


                                       -5-



either person or property, nor be construed as an eviction of Tenant, nor work
an abatement of Rent, nor relieve Tenant from Tenant's obligations hereunder.

         16. BANKRUPTCY: If Tenant makes an assignment of its assets for the
benefit of creditors, or if Tenant files a voluntary petition in bankruptcy, or
if an involuntary petition in bankruptcy or for receivership is instituted
against Tenant and the same is not dismissed within ninety (90) days of the
filing thereof, or if Tenant is adjudged bankrupt, then and in any of the
foregoing events, to the extent permitted by law, this Lease will immediately
cease and terminate at the option of Landlord with the same force and effect as
though the date of said event was the day herein fixed for expiration of the
Term.

         17. DEFAULTS & REMEDIES: If Tenant fails to pay the Rent, or any
installment thereof, within five (5) days after the same becomes due and
payable, or if Tenant violates or fails or neglects to keep and perform any of
the covenants, conditions, and agreements herein contained on the part of Tenant
to be kept and performed within thirty (30) days after receipt of written notice
of such failure or neglect, or if the Premises becomes vacant or deserted, then,
and in each and every such event, at the option of Landlord, Tenant's right of
possession will thereupon cease and terminate, and to the extent permitted by
law Landlord will be entitled to the possession of the Premises and to re-enter
the same without demand of Rent or demand of possession and may forthwith
proceed to recover possession of the Premises by process of law, ANY NOTICE TO
QUIT OR OF INTENTION TO RE-ENTER THE SAME BEING HEREBY EXPRESSLY WAIVED BY
TENANT. In the event of such re-entry by process of law or otherwise, Tenant
nevertheless agrees to remain answerable for any and all damage, deficiency or
loss of Rent which Landlord may sustain by such re-entry, including reasonable
attorneys' fees and court costs; and in such case, Landlord reserves full power,
which is hereby acceded to by Tenant, to relet the Premises for the benefit of
Tenant, in liquidation and discharge, in whole or in part, as the case may be,
of the liability of Tenant under the terms and provision of this Lease. In
addition to the foregoing remedies, Landlord will also have the following
remedies to the extent permitted by law and all other remedies afforded to it at
law or in equity, all of which shall be cumulative: to terminate this Lease; to
declare due and payable all Rent for the unexpired Term as and when the same
becomes due and payable or to defer any suit until after the Term without
thereby prejudicing its rights; to accelerate the Rent for the remainder of the
Term and declare it all immediately due and payable [with a present value
discount two (2) whole percentage points below the prime rate published in The
Wall Street Journal on the date Landlord elects said remedy]; and to bring an
action for specific performance, injunction, or other equitable relief to
prevent any threatened or impending default or to end any existing default. In
addition, Landlord may perform any obligation which Tenant has failed to perform
after the expiration of any applicable notice and/or cure period (except in an
emergency, when no notice or cure period will be necessary or afforded), all at
the cost of Tenant as Additional Rent payable upon demand. Tenant shall also pay
all expenses (including, without limitation, reasonable attorneys' fees)
incurred by Landlord following a default, whether or not suit is instituted; the
same shall be Additional Rent payable upon demand. In determining the Rent due
for the balance of the Term, all Additional Rent shall be determined by
projecting into the future the Additional Rent payable on the date of default
increasing by a compounding five percent (5%) per Lease Year. No waiver of any
breach of any covenant, condition, or agreement herein contained shall operate
as a waiver of the covenant, condition or agreement itself, or of any subsequent
breach thereof. No provision of this Lease shall be deemed to have been waived
by Landlord unless such waiver shall be in writing signed by Landlord. No
payment by Tenant or receipt by Landlord of a lesser amount than the Rent herein
stipulated shall be deemed to be other than on account of the earliest
stipulated Rent, nor shall any endorsement or statement on any check or any
letter accompanying any check or payment as Rent be deemed an accord and
satisfaction, and Landlord may accept such check or payment without prejudice to
Landlord's right to recover the balance of such Rent or pursue any other remedy
provided in this Lease. Landlord shall have a lien for the payment of the Rent
upon all of the goods, wares, chattels, fixtures, furniture and other personal
property of Tenant which may be in or upon the Premises, Tenant hereby
specifically waiving any and all exemptions allowed by law; such lien may be
enforced on the nonpayment of any installment of Rent by the taking and selling
of such property in the same manner as in the case of chattel mortgages on
default thereunder; said sale is to made upon ten (10) days notice served upon
Tenant by posting upon the Premises or such lien may be enforced in any other
lawful manner at the option of Landlord.

         18. RIGHTS OF LENDERS, GROUND LESSORS AND PURCHASERS: This Lease is
subject and subordinate to all ground or underlying leases (hereinafter
collectively referred to as "GROUND LEASES") and to all of the terms and
provisions and liens of all mortgages and/or deeds of trust (hereinafter
collectively referred to as "MORTGAGES") which may now or hereafter affect this
Lease or the Building, and to all renewals, modifications, consolidations,
replacements, amendments and extensions thereof. This clause is self-operative,
and no lessor or mortgagee (as used in this Lease, "MORTGAGEE" includes any
mortgagee under a mortgage, any beneficiary or trustee under a deed of trust,
and any lender or other secured party under a deed to secure debt or other
instrument similar to any of the foregoing) may require any instrument of
subordination. In confirmation of such subordination, Tenant shall execute
promptly any certificate that Landlord may request. Tenant hereby constitutes
and appoints Landlord Tenant's attorney-in-fact to execute any such certificate
or certificates for and on behalf of Tenant. Notwithstanding the foregoing, a
ground lessor or mortgagee may recognize this Lease and, in the event of the
termination of any ground lease or any foreclosure or similar sale or deed in
lieu thereof under such mortgage, this Lease will continue in full force and
effect at the option of the ground lessor or mortgagee (or the purchaser at any
such foreclosure sale). Tenant will, at the written request of the ground lessor
or mortgagee (or the purchaser at any such foreclosure sale), execute,
acknowledge and deliver any instrument that has for its purpose and effect the
subordination of such ground lease or mortgage to this Lease. In any case, such
ground lessor, mortgagee, landlord or successor shall not be bound by any
prepayment on the part of Tenant of any Rent for more than one month in advance,
so that Rent shall be payable under this Lease in accordance with its terms as
if such prepayment had not been made; nor shall any such ground lessor,
mortgagee, landlord or successor be liable for any default under this Lease by
any predecessor Landlord or subject to any counterclaim, set-off or defense as a
result of any such default; and provided, further, such ground lessor,
mortgagee, landlord or successor shall not be bound by this Lease or any
amendment or modification of this Lease unless Landlord's ground lessor or
mortgagee, as may be applicable, had approved the same in writing. At any time
and from time to time, upon the request and at the sole option of any successor
to Landlord's interest, Tenant shall attorn to any successor to Landlord's
interest, whether such successor acquires its interest by voluntary conveyance,
foreclosure, deed in lieu of foreclosure, termination or expiration of a ground
lease, or any other method, and in that event this Lease shall continue as a
direct lease between Tenant and such landlord or its successor and the prior
Landlord shall be released from all obligations and liability under this Lease
arising after the date of transfer. The terms of this Lease are subject to
approval by the Landlord's ground lessor(s) and lender(s), and such approval is
a condition precedent to Landlord's obligations hereunder. Tenant shall furnish
copies of any default or similar notices delivered by Tenant to Landlord
hereunder at the same time to each ground lessor or mortgagee, now or at anytime
and from time to time hereafter, and no such notice shall be effective unless
and until a copy of it is sent to each such ground lessor or mortgagee, provided
that Tenant has been afforded written notice of the name and address of such
party. Each such ground lessor or mortgagee may cure any default by Landlord
within the same time period afforded Landlord to cure any such default, plus
such additional period of time thereafter as may be reasonably necessary for
such ground lessor or mortgagee to cure such default.

         19. CONDEMNATION: If the Premises or any part thereof is taken or
condemned for public or quasi-public use or purpose by any competent authority,
or conveyed in lieu of being taken or condemned, Tenant will have no claim
against Landlord and will not have any claim or right to any portion of the
amount that may be awarded to Landlord as damages or paid as a result thereof.
All right of Tenant to damages therefor, if any, are hereby assigned by Tenant
to Landlord. Upon such condemnation or taking, or conveyance in lieu thereof,
the Term shall terminate from the date of such governmental taking or
condemnation, or conveyance in lieu thereof, and Tenant will have no claim
against Landlord for the value of any unexpired Term. Nothing in this Paragraph
limits or affects Tenant's right to seek any separate award from the condemning
authority as long as Tenant does not thereby reduce, delay or in any other way
affect Landlord's claim or award.

         20. SUCCESSORS: All rights, remedies and liabilities herein given to or
imposed upon either of the parties hereto extend to their respective heirs,
executors, administrators, successors and permitted assigns.

         21. TENANT HOLDOVER: If Tenant continues to remain in the Premises
after the termination or expiration of the Term, then and in that event Tenant
will become a tenant by the month at 125% of the Base Rent per month payable for
the last month before the expiration or termination of the Term plus all
Additional Rent that may be incurred during any such holdover, but in no event
less than the then market rent for the Premises. Holdover Rent will commence
with the first day following the end of the Term. During any holdover, each
party must give the other at least thirty (30) days written notice to quit the
Premises, except in the event of any default by Tenant, in which event Tenant
will not be entitled to any notice to quit, the usual thirty (30) days' notice
to quit being hereby expressly waived; PROVIDED, HOWEVER, that if Tenant holds
over after the expiration of the Term hereby created, and if Landlord desires to
regain possession of the Premises promptly at the expiration of the Term, then
at any time prior to Landlord's acceptance of Rent from Tenant as a monthly
tenant hereunder, Landlord, at its option, may forthwith re-enter and take
possession of the Premises without process, or by any legal process in force.
Tenant shall not use FORCE MAJEURE as an excuse for any holding over.

         22. POSSESSION: Landlord shall give possession of the Premises to
Tenant on the Commencement Date. If Landlord is unable to give possession of the
Premises on the Commencement Date because any portion of the Premises are
located in a Building being constructed that has not been sufficiently completed
to make the Premises ready for occupancy, or because a certificate of occupancy
has not been procured, or if Landlord is unable to give possession of the
Premises on the Commencement Date because of the holding over or retention of
possession by any previous tenant, occupant or owner, or if repairs,
improvements or decorations of the Premises or of the Building are not
completed, or for any other reason, Landlord will not be subject to any
liability for the failure to give possession on the Commencement Date. No such
failure to give possession on the Commencement Date will affect in any other
respect the validity of this Lease or the obligations of Tenant hereunder, nor
will the same be construed in any way to extend the Term. If Landlord permits
Tenant to enter into the possession of the Premises or a portion of the Premises
prior to the Commencement Date, such occupancy shall be deemed to be under all
terms, covenants, conditions and provisions of this Lease.

         23. JOINT AND SEVERAL LIABILITY: If Tenant consists of more than one
individuals and/or entities, then the liability of each of them for Tenant's
obligations under this Lease shall be joint and several.

         24. PRONOUNS: Feminine, masculine or neuter pronouns shall be
substituted for each other, and the plural shall be substituted for the singular
number and vice versa in any place in which the context may require such
substitution.

         25. LATE PAYMENT: If Tenant fails to pay any Rent on or before the
fifth (5th) day after such payment becomes due and payable, Tenant shall pay to
Landlord a late charge of five percent (5%) of the amount of such overdue
payment. In addition, any Rent not paid when due will bear interest at the
lesser of eighteen percent (18%) per annum or the maximum rate allowed by law
until paid. Acceptance of the foregoing sums shall not constitute a waiver of
the default. Upon Landlord's receipt of any check from Tenant which is
dishonored for payment, Landlord may require Tenant to make all future payments
due to Landlord hereunder by cash, certified or cashier's check.

         26. NOTICES: All notices required or desired to be given hereunder by
either party to the other shall be given by hand, by overnight courier or by
certified or registered mail. Notices shall be effective upon receipt (refusal
to accept delivery or the inability to make delivery due to an incorrect or
outdated address being provided by the intended recipient shall constitute
receipt). Notices to the respective parties must be addressed as follows:

         If to Landlord -           Monte R. Black
                                    9711 Lancaster Road, S.E.
                                    Hebron, Ohio  43025

         If to Tenant -             MPW Industrial Services, Inc.

                                    Hebron, Ohio  43025
                                    Attn:  Daniel P. Buettin

Either party may, by like written notice, designate a new address or addressee
to which notices must be directed. Tenant shall provide a copy of any notice
given to Landlord to any mortgagee or ground lessor of whom Tenant has notice.
Notices may be given by authorized agents or attorneys on behalf of a party.

         27. ESTOPPEL CERTIFICATES: Within ten (10) days after request therefor
by Landlord or any ground lessor or mortgagee of the Building, Tenant shall
execute and deliver estoppel certificates certifying, among other things: the
text of this Lease and any amendments thereto; whether this Lease has been
amended and, if so, the date of each such amendment; whether this Lease is in
full force and effect and, if not, the reason therefor; whether any default or
any situation which could be a default after the giving of notice or the
expiration of any cure period (or both) exists under this Lease on the part of
Landlord or Tenant and, if so, specifying the default or potential default;
whether Tenant has taken possession of the Premises; whether the Premises have
been completed in accordance with the terms of this Lease and all bills therefor
paid and, if not, what remains to be done or paid; the Commencement Date and the
expiration date of the Term; whether Tenant has any renewal options, expansion
options, or rights to purchase

                                       -7-



and, if so, identifying the conditions and periods when they may be exercised;
the date Rent commenced to accrue and the date to which Rent has been paid;
whether any security deposit has been posted; whether Tenant has any knowledge
or any environmental problem affecting the Premises or the Building; and such
other matters as may be reasonably requested.

         28. NO PERSONAL LIABILITY: Notwithstanding any provision of this Lease
to the contrary or any general rule of law, in no event whatsoever shall
Landlord or any of its shareholders, partners, directors, officers, employees,
agents or other principals have any personal liability whatsoever with respect
to this Lease, and no such personal liability shall be sought, obtained or
enforced. Any liability of Landlord under this Lease may be enforced solely
against Landlord's equity interest in the Land and Building; no other properties
or assets of Landlord are subject to this Lease or Landlord's liabilities
hereunder.

         29. BROKERS: Each party represents and warrants to the other that it
has not engaged or used any broker or finder in connection with this Lease. Each
party shall defend, indemnify and hold the other party harmless from and against
any breach by the indemnifying party of the representation and warranty set
forth in the first sentence of this Paragraph. Tenant shall defend, indemnify
and hold Landlord's ground lessors and mortgagees harmless from and against any
breach by Tenant of the representation and warranty set forth in the first
sentence of this Paragraph. No broker is a third party beneficiary of this
Lease.

         30. COMPLETE AGREEMENT; NO ORAL MODIFICATIONS: This Lease represents
the complete and integrated agreement of the parties with respect to the
Premises and, except as set forth herein, there are no other agreements,
covenants, representations or warranties (express or implied) between the
parties. Nothing in this Lease shall be deemed or construed to create a
partnership or joint venture or to create any relationship other than landlord
and tenant. This Lease may not be amended except by a written document signed by
the party to be bound thereby.

         31. GOVERNING LAW AND RULES OF INTERPRETATION: This Lease is governed
by the laws of the State of Ohio without regard to conflicts of laws. Without
limiting a party's right to bring any action in any other jurisdiction or forum,
each party submits itself to the jurisdiction of the federal and local courts
sitting in the State of Ohio and to venue therein. It is the intent of the
parties that this Lease will be enforceable to the fullest extent permitted by
law. If any provision of this Lease is capable of two or more interpretations or
can be reformed so as to comply with applicable law while giving effect to the
intent of such provision, then such provision shall be interpreted in the way
most likely to be in compliance with applicable law. Although the printed
provisions of this Lease were drawn by Landlord, this Lease shall not be
construed either for or against Landlord or Tenant.

                              FIRST LEASE AMENDMENT
                              ---------------------



         THIS FIRST LEASE AMENDMENT (this "First Amendment"), is made this
11th day of February, 1998, by and between THE BLACK FAMILY LIMITED
PARTNERSHIP, an Ohio limited partnership ("LANDLORD") and MPW INDUSTRIAL
SERVICES, INC., an Ohio corporation ("TENANT").


                                   WITNESSETH:
                                   -----------


         WHEREAS Landlord and Tenant have heretofore entered into that certain
lease, dated as of May 1, 1996 (the "LEASE"), for certain premises containing a
35,500 square foot industrial facility located on approximately 5.99 acres of
land in Chesterfield Township, Macomb County, Michigan (the "Premises");

         WHEREAS, the Lease grants to Tenant, INTER ALIA, an option to renew the
Term for one additional five (5) year period, and Tenant and Landlord wish to
modify the extension rights of Tenant; and

         WHEREAS, the parties wish to further modify certain terms of the Lease
in accordance with the provisions of this First Amendment.

         NOW, THEREFORE, in consideration of the mutual premises contained
herein, the sum of One Dollar ($1.00) in hand paid, and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged,
Landlord and Tenant, intending to be legally bound, hereby agree as follows:

         1. DEFINED TERMS: All terms used herein but not defined shall have the
meanings ascribed thereto in the Lease.

         2. TERM:

            (a)   Subparagraph 2(a)is modified by deleting the phrase "April 30,
                  2001" in the second line thereof and inserting in lieu thereof
                  the phrase "November 30, 2004."

            (b)   Subparagraph 2(b) of the Lease is hereby deleted, and the
                  following is inserted in lieu thereof:

                  RENEWAL TERM. Tenant may, at its sole option, choose to extend
                  the term of this Lease for two (2) additional periods of five
                  (5) years each (a "RENEWAL TERM") under such terms and
                  conditions as Landlord and Tenant will negotiate, based upon a
                  fair market appraisal of the Premises. Tenant shall provide
                  Landlord with written notice of Tenant's intent to exercise
                  this option not later than one hundred twenty (120) days prior
                  to the expiration of the Initial Term or first Renewal Term,
                  as applicable. As used in this Lease, "TERM" means both the
                  Initial Term and, if Tenant exercises its option(s), any
                  Renewal Term. As used in this Lease, "LEASE YEAR" means each
                  consecutive twelve (12) month period of the Term, starting on
                  the Commencement Date of this Lease.

         3. RENT: Subparagraph 3(a) of the Lease is hereby deleted, and the
following is inserted in lieu thereof:

            (a)   Tenant shall pay as "BASE RENT" for each Lease Year during the
                  Initial Term the sum of Two Hundred Eighty-Eight Thousand and
                  No/100 Dollars ($288,000.00), payable in advance, in equal
                  monthly installments of Twenty-Four Thousand and No/100
                  Dollars ($24,000.00). The first and last monthly installments
                  are due and payable on the execution of this Lease and the
                  remaining installments are due and payable in advance on the
                  first day of each and every month during the Term, without
                  offset or deduction, to Landlord at the address set forth in
                  PARAGRAPH 26 or at such other place as Landlord may hereafter
                  designate in writing. Rent checks are to be made payable to
                  Landlord, or such other person, form or corporation as
                  Landlord may designate in writing.

                  A new subparagraph 3(e) is inserted in the lease as follows:

            (e)   For each Renewal Term, Tenant shall notify Landlord that
                  Tenant desires to exercise its option to extend the Term of
                  this Lease for the next ensuing five (5) year period, and to
                  obtain an appraisal of the Premises to determine the market
                  rent for the Premises by delivering written notice to Landlord
                  not less than one hundred twenty (120) days prior to the
                  beginning of each renewal Term. Tenant shall include in such
                  notice the name of an MAI appraiser selected by Tenant which
                  has an office in Macomb County, Michigan. Landlord shall
                  within thirty (30) days following receipt of such notice from
                  Tenant give written notice to Tenant setting forth the name of
                  a second MAI appraiser with an office in Macomb County,
                  Michigan. If Landlord fails to notify Tenant of the name of an
                  appraiser within the thirty (30) day period, then the
                  appraiser selected by Tenant shall determine the market rent
                  and the decision of said appraiser shall be binding upon the
                  parties hereto. If Landlord has selected an appraiser in
                  accordance with the provisions of this Paragraph, then the
                  appraiser selected by Landlord and the appraiser selected by
                  Tenant shall meet and select a third MAI appraiser with an
                  office in Macomb County, Michigan. The appraiser selected by
                  Landlord and the appraiser selected by Tenant shall each
                  appraise the Premises for purposes of obtaining said market
                  rent. The third appraiser shall determine and notify Landlord
                  and Tenant which of the two appraisals made by Landlord's and
                  Tenant's appraisers more closely reflects the market rent of
                  the




<PAGE>   2


                                       -2-



                  Premises, and the decision of the third appraiser shall be
                  binding upon the parties hereto. Notwithstanding anything in
                  this paragraph to the contrary, in no event shall the Base
                  Rent for any Renewal Term be less than the Base Rent for the
                  previous Renewal Term or the Initial Term, as applicable.

         4. COMPLETE AGREEMENT; NO ORAL MODIFICATION: The Lease, as modified by
this First Amendment, represents the complete and integrated agreement of the
parties with respect to the Premises and, except as set forth herein, there are
no other agreements, covenants, representations or warranties (express or
implied) between the parties. The Lease, as modified by this First Amendment,
may not be amended except by a written document signed by the party to be bound
thereby. The parties hereby ratify and confirm the Lease, as modified hereby.

         5. GOVERNING LAW AND RULES OF INTERPRETATION: This First Amendment is
governed by the laws of the State of Michigan without regard to conflicts of
laws. Without limiting a party's right to bring any action in any other
jurisdiction or forum, each party submits itself to the jurisdiction of the
federal and local courts sitting in the State of Michigan and to venue therein.
It is the intent of the parties that this First Amendment be enforceable to the
fullest extent permitted by law. If any provision of this First Amendment is
capable of two or more interpretations or can be reformed so as to comply with
applicable law while giving effect to the intent of such provision, then such
provision shall be interpreted in the way most likely to be in compliance with
applicable law. Although the printed provisions of this First Amendment were
drawn by Landlord, this instrument shall not be construed either for or against
Landlord or Tenant.

IN WITNESS WHEREOF, Landlord and Tenant have executed this First Amendment under
seal as of the day and year first above written.

terms and conditions of this Lease.

SECTION 2. TERM, RENT AND LESSOR USAGE

         2.1 Except as set forth in the next succeeding sentence, the leasing of
the Aircraft by Lessor to Lessee shall be for a Term beginning on February 1,
1998 and ending on January 31, 2003 unless this Lease shall have been terminated
or extended in accordance with the terms hereof. Notwithstanding the previous
sentence, either party shall have the right to terminate this lease on not less
than 120 days' prior written notice to the other party, and the date set forth
in such written notice shall be deemed to be the expiration of the Term.

the 1st day of each month commencing February 1, 1998 plus applicable state and
local sales taxes with respect to this Lease and payable in United States
currency. The parties agree that the Base Rent is calculated on the basis that
Lessee will use the Aircraft for no more than 250 engine hours per year (the
"Base Usage"). To the extent that for any year of the Term, the Aircraft is used
for more than the Base Usage, Lessee shall pay to Lessee, no later than 45 days
following the end of such year, an amount equal to $250 for each engine hour
that the Aircraft is used by Lessee in excess of the Base Usage (the "Excess

         2.4 As additional consideration for this Lease, Lessee agrees that
Lessor shall have the right to use the Aircraft, including the pilots, fuel and
other goods and services provided with the Aircraft, at mutually convenient
times. Lessor agrees to pay Lessee for such use of the Aircraft at a rate of
$700 per engine hour, which amount shall be payable upon receipt of an invoice
therefor, or may be setoff by Lessee from amounts of Rent due hereunder.

SECTION 3. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF
           LESSOR

         Lessor represents, warrants and agrees:

         3.1 that during the term of this Lease as long as no Event of Default
has occurred, Lessee's use of the Aircraft shall not be interrupted by Lessor or
anyone claiming through or under Lessor.

         3.2 that Lessor is a limited liability company with authority to enter
into, and consummate, the transactions contemplated by, this Lease and that this
Lease has been duly authorized, executed and delivered by the Lessor and
constitutes a valid, enforceable and binding obligation of the Lessor in
accordance with its terms except as enforceability may be limited by bankruptcy,
insolvency, reorganization or other laws of general application affecting the
enforcement of creditor's rights and general principles of equity, including
without limitation, specific performance.

         LESSEE EXPRESSLY AGREES TO LEASE THE AIRCRAFT "AS-IS, WHERE-IS". LESSOR
SHALL NOT BE DEEMED TO HAVE MADE, AND LESSOR HEREBY DISCLAIMS, ANY OTHER
REPRESENTATION OR WARRANTY, EITHER EXPRESS OR IMPLIED, AS TO ANY MATTER

LESSOR BE LIABLE REGARDLESS OF ANY ACTUAL OR ALLEGED NEGLIGENCE OF LESSOR, OR
FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES OR FOR STRICT OR ABSOLUTE LIABILITY IN
TORT, AND ANY RISKS WITH RESPECT THERETO SHALL BE ASSUMED BY LESSEE. THE
FOREGOING SHALL NOT, HOWEVER, BE CONSTRUED TO RELIEVE LESSOR FROM LIABILITY TO
LESSEE FOR DAMAGES PROXIMATELY CAUSED BY LESSOR'S GROSS NEGLIGENCE OR WILLFUL
MISCONDUCT OR LESSOR'S ACTS OF NEGLIGENCE IN THE UNDERTAKING OF AFFIRMATIVE
ACTS. The warranties set forth hereinabove are in lieu of all other warranties
of Lessor, whether written, oral or implied with respect to this Lease or the

obligations of Lessee pursuant to Section 5 hereof, which obligations are

Except as otherwise expressly provided herein, this Lease shall not terminate,
nor shall the obligations of Lessee be affected, by reason of any defect in or
damage to, or any loss or destruction of, the Aircraft or any part thereof from
whatsoever cause, or the interference with the use thereof by Lessor or any

any location within the continental United States as Lessor shall direct.
Subject to the consent of the maintenance or warranty provider, as applicable,
Lessee shall, upon request, assign to Lessor its rights under any maintenance
service contract or warranty for the Aircraft, any Engine or Part thereof. All
expenses for return of the Aircraft and delivery of the aforementioned logs,
manuals and data shall be borne by Lessee, except that any cost to assign any
maintenance contract or warranty shall be Lessor's obligation. If Lessee desires
to obtain for its own use the United States "N" registration number that is on

<PAGE>   11



         6.3 DELAYED RETURN. If Lessee fails to return the Aircraft on
termination or expiration of the Term, Lessor shall be entitled to damages equal
to the Daily Prorated Rent for the Aircraft. Such damages for retention of the
Aircraft after termination or expiration of the Term shall not be interpreted as
an extension or reinstatement of the Term.

         6.4 SURVIVAL. All of Lessor's rights contained in this Section shall
survive the expiration or other termination of this Lease.

SECTION 7. LIENS

         Title to the Aircraft shall remain in the Lessor exclusively. Lessee
will not directly or indirectly create, incur, assume or suffer to exist any
Liens on or with respect to the Aircraft or any part thereof, Lessor's title
thereto or any interest of Lessor therein (and Lessee will promptly, at its own
expense, take such action as may be necessary duly to discharge any such Lien),
except (a) the respective rights of Lessor and Lessee as herein provided, (b)
the rights of others under agreements or arrangements to the extent expressly
provided by the terms of Section 16 hereof, (c) Lessor's Liens, (d) Liens for

provided Lessor), and (e) inchoate materialmen's, mechanics', workmen's,
repairmen's, employees' or other like Liens arising in the ordinary course of
business of Lessee for sums not yet delinquent or being contested in good faith

judgment have been provided Lessor).

SECTION 8. TAXES

         Lessee shall not be liable for any taxes on or measured by the income
or net worth of Lessor. Lessee agrees to pay and to indemnify Lessor for, and
hold Lessor harmless from and against, all other license and registration fees,
sales, use, excise, personal property, ad valorem, value added, leasing, leasing
use, stamp, landing, airport use or other taxes, levies, imposts, duties,
charges, or withholdings of any nature, together with any penalties, fines or
interest thereon ("Impositions"), arising out of the transactions contemplated
by this Lease and imposed against Lessor, Lessee or the Aircraft or any part
thereof by any Federal, state, local or foreign government or other taxing
authority upon or with respect to the Aircraft or any part thereof or upon the
sale, purchase, ownership, delivery, leasing, possession, use, operation,
return, transfer or other disposition thereof or upon the rentals, receipts or
earnings arising therefrom (other than those Impositions arising therefrom after
the expiration of the Lease term, for which Lessor shall be responsible), or
upon or with respect to this Lease, unless, and only to the extent that, Lessee
shall have given to Lessor written notice of any such Imposition, which notice
shall state that such Imposition is being contested by Lessee in good faith with
due diligence and by appropriate proceedings. The foregoing notwithstanding,
Lessor, not Lessee, shall be responsible for any Impositions, including but not
limited to fines, penalties and interest, resulting from Lessor's failure to
file returns, reports and/or pay in a timely manner any Impositions assessed
Lessor, unless Lessor and Lessee agree in writing that Lessee and not Lessor
will file any such returns or reports. If a claim is made against Lessee or
Lessor for any Imposition, the party receiving notice of such claim shall
promptly notify the other, but the failure of either party to so notify the
other shall not relieve Lessee of its obligation under this Section to indemnify
Lessor, provided that the party failing to promptly notify the other party shall


                                        8

<PAGE>   12

proximately caused by such failure.

SECTION 9. MAINTENANCE AND OPERATION; COMPLIANCE AND USE; REPLACEMENT PARTS;
           ADDITIONS

         9.1 MAINTENANCE AND OPERATION. Except as set forth in the next
succeeding sentence, Lessee shall (i) maintain, inspect, service, repair,
overhaul and test the Airframe and each Engine in accordance with (a) all
required procedures under any maintenance manuals initially furnished with the
Aircraft, including any subsequent amendments or supplements to such manuals
issued by the Airframe Manufacturer or Engine Manufacturer from time to time,
(b) all mandatory "Service Bulletins" and "Aircraft Modification Kits" issued,
supplied, or available by or through the Airframe Manufacturer and/or the Engine
Manufacturer with respect to the Aircraft, and (c) all "airworthiness alerts"
and Airworthiness Directives issued by the Federal Aviation Administration or
similar regulatory agency having jurisdictional authority, and whenever possible
causing compliance to such Directives to be completed through corrective
modification in lieu of operating manual restrictions; (ii) maintain all
records, logs and other materials required by the Federal Aviation
Administration to be maintained in respect of the avionics, Airframe and each
Engine or by the Airframe Manufacturer or Engine Manufacturer for enforcement of
any warranties; (iii) with due diligence after written request, furnish to
Lessor such information as may be required to enable Lessor to timely file any
reports required by any governmental authority as a result of Lessor's ownership
of the Aircraft; and (iv) not change the Aircraft's primary hangar location
without the consent of Lessor, which consent shall not be unreasonably withheld.
Notwithstanding the foregoing, Lessor shall be responsible for the costs and
expenses of the Hot Section Inspection and 3,000 Hours Time Between Overhaul, as
such terms are defined in the Cessna Maintenance Manual. Lessee shall not remove
the Aircraft from the Continental United States, or from the base indicated for
a period in excess of thirty (30) days, without the express, prior written
consent of Lessor. All maintenance procedures required by Section 9.1(i) shall
be undertaken and completed in accordance with Airframe Manufacturer's or Engine
Manufacturer's required procedures, and only by properly trained, licensed, and
certificated maintenance sources and maintenance personnel, so as to keep the
Airframe and each Engine in as good operating condition as when delivered to
Lessee hereunder, ordinary wear and tear excepted, and so as to keep the
Aircraft in such operating condition as may be necessary to enable the
airworthiness certification of such Aircraft to be maintained in good standing
at all times under the Federal Aviation Act. Lessee further agrees that it shall
comply with the Engine Manufacturer's maintenance service program currently in
force (a certified copy of which has been provided to Lessor), or an equivalent
maintenance program authorized in writing by Lessor, for the full term of the
Lease and shall take all steps necessary under the terms thereof to keep such
maintenance service program in effect with respect to the Engines.

         9.2 COMPLIANCE AND USE. Lessee agrees that the Aircraft will be
maintained, used and operated in compliance with any and all statutes, laws,
ordinances, regulations and mandatory standards or directives issued by any
governmental agency applicable to the maintenance, use or operation thereof, in
compliance with any airworthiness certificate, license or registration relating
to the Aircraft issued by any agency and in a manner that does not modify or
impair any existing warranties on the Aircraft or any part thereof. Lessee also
represents and warrants that it will operate the Aircraft primarily in the
conduct of its business and not operate or permit the Aircraft to be


                                        9

<PAGE>   13



operated at any time or in any geographic area when insurance required by the
provisions of Section 12 hereof shall not be in effect. Throughout the term of
this Lease, except as otherwise expressly stated, the possession, use and
maintenance of the Aircraft shall be at the sole risk and expense of Lessee and
the Aircraft shall be based and properly hangared at the primary hanger
location. At all times the Aircraft will be operated only by duly-qualified,
currently-certificated pilots having the minimum total pilot hours required by
the requirements of Lessee's insurance carriers, and for such certification by
the Federal Aviation Administration.

         9.3 REPLACEMENT PARTS. Lessee shall as soon as practicable replace all
Parts that may from time to time become worn out, lost, stolen, destroyed,
seized, confiscated, damaged beyond repair or permanently rendered or declared
unfit for use for any reason whatsoever (such substituted parts hereinafter
called Replacement Parts). In addition, in the ordinary course of maintenance,
service, repair, overhaul or testing, Lessee may, at its own cost and expense,
remove serviceable parts, provided that Lessee shall, at its own cost and
expense, replace such serviceable Parts as promptly as practicable. All
Replacement Parts shall be free and clear of all Liens except Lessor Liens and
shall be in as good operating condition as, and shall have a value and utility
as least equal to, the Parts replaced assuming such replaced Parts were in the
condition and repair required to be maintained by the terms hereof. All Parts at
any time removed from the Airframe or any Engine shall remain the property of
Lessor, no matter where located, until such time as such Parts shall be replaced
by Parts that have been incorporated or installed in or attached to the Airframe
or such Engine and which meet the requirements for Replacement Parts specified
above. Immediately upon any Replacement Part becoming incorporated or installed
in or attached to the Airframe or any Engine as above provided, without further
act, (a) title to the removed Part shall thereupon vest in Lessee, free and
clear of all rights of Lessor and shall no longer be deemed a Part hereunder,
(b) title to such Replacement Part shall thereupon vest in Lessor, and (c) such
Replacement Part shall become subject to the Lease and be deemed part of the
Airframe or Engine, as the case may be, for all purposes hereof to the same
extent as the Parts originally incorporated or installed or attached to the
Airframe or such Engine.

         9.4 AIRCRAFT MARKING. Lessee agrees, at its own cost and expense, to
(a) cause the Airframe and the Engines to be conspicuously identified with the
Registration Number N57VP; (b) notify Lessor of any change in an Engine serial
number resulting from a replacement of an Engine pursuant to this Lease and file
an appropriate Lease Supplement with the FAA with respect thereto; (c)
prominently display on the Aircraft the Registration Number N57VP; (d) affix and
maintain in the Aircraft reasonably adjacent to the airworthiness certificate a
nameplate bearing the Aircraft Registration Number and such other markings as
from time to time may be required by law or otherwise deemed necessary or
advisable by Lessor in order to protect the title of Lessor to the Aircraft and
the rights of Lessor under this Lease.

         9.5 ALTERATIONS. Lessee shall not make any alterations, additions, or
improvements to the Aircraft without the express, prior written consent of
Lessor. Any additions and improvements to the Aircraft during the term of this
Lease shall be at the sole cost and expense of Lessor. All additions and
improvements of whatsoever kind or description made to the Aircraft shall belong
and become the property of Lessor upon their creation and Lessee shall have no
interest therein.

SECTION 10. INSPECTION

         Lessor shall have the right, upon reasonable notice, but not the duty,
to inspect the Aircraft and any Engine at any reasonable time at Lessee's
primary hangar location. Lessee shall, at any reasonable time, make Lessee's
books and records pertaining to the Aircraft available to Lessor for inspection
at Lessee's primary hangar location.

SECTION 11. LOSS OR DESTRUCTION; REQUISITION OF USE

         11.1 NOTIFICATION OF EVENT OF LOSS AIRCRAFT. Upon the occurrence of an
Event of Loss with respect to the Airframe, or any Engine (whether or not then
installed on such Airframe), or any engine installed on such Airframe, Lessee
shall notify Lessor thereof within ten (10) days of the date thereof. Within
thirty (30) days following the date of an Event of Loss with respect to the
Airframe or the Airframe and any Engines then installed thereon Lessee shall pay
the lessor the Casualty value of the Aircraft determined as of the Rent Date
immediately preceding the date of such Event of Loss plus an amount equal to the
Daily Prorated Rent, together with any Rent then due. Upon making Payment of
such Casualty Value in respect thereof and all Rent due and owing with respect
thereto, Lessee's obligation to pay further Rent for the Aircraft for months
commencing subsequent to such Event of Loss shall cease. Upon making the payment
of the Casualty Value together with any rent due and owing, Lessor shall convey
all of Lessor's right, title and interest in the Aircraft to Lessee or to
Lessee's insurance carrier, as Lessee may direct, free and clear of any and all
Lessor's Liens and Lessor shall have no further rights, title or interest in the
Aircraft.

         11.2 RISK OF LOSS: NO RELEASE OF OBLIGATIONS. Lessee shall bear the
risk of loss and shall not be released from its obligations hereunder in the
event of any damage to the Aircraft or any part thereof or any Event of Loss
relating thereto.

         11.3 APPLICATION OF INSURANCE PROCEEDS. As between Lessor and Lessee,
it is agreed that all insurance proceeds under policies required hereby received
as the result of the occurrence of an Event of Loss with respect to the Aircraft
will be applied as follows: proceeds that shall not exceed the Casualty Value
required to be paid by Lessee pursuant to Section 11.1 shall be applied in
reduction of Lessee's obligation to pay such Casualty Value, if not already paid
by Lessee, or, if already paid by Lessee and no Event of Default has occurred
and is continuing shall be applied to reimburse Lessee for its payment of such
Casualty Value, and the balance, if any, of such insurance proceeds remaining
thereafter will be paid to the order of Lessee. The proceeds of any insurance
received by Lessor on account of or for any loss not constituting an Event of
Loss shall be released upon written application signed by the President, the
Treasurer or a Vice President of Lessee for the payment of, or to reimburse the
Lessee for the payment of, the cost of repairs and Replacement Parts (which
application shall be accompanied by evidence satisfactory to Lessor of such cost
and evidence of good title to such Replacement Parts in Lessor and a statement
(i) that such repairs have been completed and (ii) that no Event of Default has
occurred and is continuing) and any balance remaining shall be paid to Lessee;
provided that, if Lessee is at the time of such application or payment in
Default in the payment of any other liability of Lessee to Lessor hereunder,
such proceeds may be applied against any such liability by Lessor in its sole
discretion, and such amount shall be paid to Lessee at such time as there no
longer exists any Default or Event of Default.

SECTION 12. INSURANCE

         12.1 PUBLIC LIABILITY AND PROPERTY DAMAGE INSURANCE. Lessee represents
and warrants that it will maintain in effect, at its own expense, with insurers
of recognized responsibility reasonably satisfactory to Lessor, (a) public
liability insurance against personal injury and property damage claims
(including, without limitation, passenger legal liability) in an amount not less
than $ 50,000,000 for each single occurrence and (b) such other property damage
insurance (exclusive of manufacturer's product liability insurance) with respect
to the Aircraft as is the type and in the amounts usually carried by
corporations engaged in the same or a similar business, similarly situated with
Lessee, and owning or operating similar aircraft and engines and which covers
risks of the kind customarily insured against by such corporation. Lessee shall
provide at its own expense workmen's compensation insurance with all-states
coverage for the crew and maintenance personnel.

         12.2 INSURANCE AGAINST LOSS OR DAMAGE TO THE AIRCRAFT. Lessee
represents and warrants that it will maintain in effect, at its own expense,
with insurers of recognized responsibility reasonably satisfactory to Lessor,
all-risk ground and flight aircraft hull insurance covering the Aircraft,
including F.O.D. (foreign object damage), fire and explosion coverage, ingestion
and lightning and electrical damage, and with respect to any Engines or Parts
while removed form the Aircraft, and with respect to any engines or parts while
temporarily installed on the Aircraft, provided that such insurance shall at all
times while the Aircraft is subject to this Lease be for an amount that, when
paid, will be not less than the greater of Fair Market Sales Value or the
Casualty Value of the Aircraft from time to time. Not less than five (5) days
prior to the expiration of any policy of insurance, Lessee shall deliver to
Lessor renewals or new policies in like amounts covering the same risks.

         12.3 LESSOR AS ADDITIONAL INSURED; NOTICE. Any policies of insurance
carried in accordance with this Section and any policies taken out in
substitution or replacement for any such policies (a) shall be amended to name
Lessor, as owner of the Aircraft, as additional named insured as its interest
may appear, (b) with respect to insurance carried in accordance with Section
12.2 covering the Aircraft shall provide that any amount(s) payable thereunder
shall be paid to Lessor as loss payee (and such amounts shall be disbursed by
Lessor to Lessee or other appropriate Person in payment of the costs actually
incurred with respect to repairs made to the Aircraft so as to restore it to the
operating condition required by Section 9 hereof or shall be disbursed by Lessor
as otherwise required by this Lease), (c) shall provide that if the insurers
cancel such insurance for any reason whatsoever, or any substantial change is
made in the coverage that adversely affects the interests of Lessor, or the same
is allowed to lapse for nonpayment of premium or such insurance coverage is
reduced, such cancellation, change, lapse or reduction shall not be effective as
to Lessor for thirty (30) days following receipt by Lessor of written notice by
such insurers of such cancellation, change, lapse or reduction and (d) shall
provide that in respect of the interest of Lessor in such policies the insurance
shall not be invalidated by any action or inaction of Lessee or any other Person
(other than Lessor) and shall insure Lessor's interest, as it appears,
regardless of any breach or violation of any warranties, declarations or
conditions contained in such policies by Lessee or any other Person (other than
Lessor). Each insurance policy and its respective coverage amounts obtained in
accordance with the requirements set forth in Sections 12.1 and 12.2 shall (i)
be primary without right of contribution from any other insurance that is
carried by Lessor to the extent that such other insurance provides Lessor with
contingent and/or excess liability insurance with respect to its interest as
such in the Aircraft and (ii) expressly provide that all of the provisions
thereof, except the limits of liability, shall


                                       12

<PAGE>   16



operate in the same manner as if there were a separate policy covering each
insured, and shall waive any right of the insurers to any set-off or
counterclaim or any other deduction, by attachment or otherwise, in respect of
Lessor or Lessee. Lessee shall arrange for appropriate certification as to the
satisfaction of the requirements set forth above in this Section 12 to be
delivered promptly (and in any case not later than the Delivery Date for such
Aircraft) to Lessor by each insurer with respect thereto, which certification
shall specifically acknowledge that the insurance is in conformity with this
Section.

         12.4 REPORTS, ETC. Annually on the renewal date of insurance, Lessee
shall furnish to Lessor a report describing in reasonable detail the insurance
then carried and maintained on the Aircraft and certifying that such insurance
complies with the terms hereof and a certificate of the insurer as to such
insurance. Lessee will advise Lessor in writing promptly of any default in the
payment of any premium and of any other act or omission on the part of Lessee
which might invalidate or render unenforceable, in whole or in part, any
insurance on the Aircraft pursuant to this Section. In the event Lessee shall
fail to maintain insurance as herein provided, Lessor may, at its option,
provide such insurance, and Lessee shall, upon demand, reimburse Lessor for the
cost thereof.

SECTION 13. INDEMNIFICATION

         Lessee assumes liability for, and hereby agrees to indemnify, protect,
save and keep harmless Lessor from and against any and all liabilities,
obligations, losses, damages, penalties, claims (including, without limitation
(except as set forth in the provision below) claims involving or alleging
Lessor's negligence and claims involving or alleging strict or absolute
liability in tort), actions, suits, costs, expenses and disbursements
(including, without limitation, reasonable legal fees and expenses) of any kind
and nature whatsoever ("Claims") that may be imposed on, incurred by or asserted
against Lessor, whether or not Lessor shall also be indemnified as to any such
Claim by any other Person, in any way relating to or arising out of this Lease
or any documents contemplated hereby, or the performance or enforcement of any
of the terms hereof or thereof, or in any way relating to or arising out of the
manufacture, purchase, acceptance, rejection, ownership, delivery, lease,
sublease, possession, use, operation, maintenance, condition, registration,
sale, return, storage or other disposition of the Aircraft or any part thereof
or any accident in connection therewith (including, without limitation, latent
and other defects, whether or not discoverable and any claim for patent,
trademark or copyright infringement); provided, however, that Lessee shall not
be required to indemnify Lessor for (a) any Claim in respect of the Aircraft
arising from acts or events that occur after possession of the Aircraft has been
redelivered to Lessor in accordance with Section 6 hereof, or (b) any Claim
arising from acts that would Constitute the willful misconduct or gross
negligence of Lessor. If any claim is made against Lessee or Lessor, the party
receiving notice of such Claim shall promptly notify the other, but the failure
of the party receiving notice to so notify the other shall not relieve either
party of any obligation hereunder. Lessee shall have the right to assume the
defense of any Claim or litigation arising from any Claim through counsel
reasonably acceptable to Lessor in such matter provided if Lessee shall so
assume the defense of such Claim or litigation, Lessor shall nevertheless have
the right to participate in such defense through its counsel at the expense of
Lessor and Lessee shared equally if in Lessor's reasonable judgment such
participation is necessary to ensure against any impairment of its interests.
Lessor will cooperate with Lessee in the defense of any Claim.
LESSEE AGREES THAT LESSOR SHALL NOT BE LIABLE TO LESSEE FOR ANY
CLAIM CAUSED DIRECTLY OR INDIRECTLY BY THE INADEQUACY OF THE


                                       13

<PAGE>   17



AIRCRAFT OR ANY PART THEREOF FOR ANY PURPOSE OR ANY DEFICIENCY OR DEFECT THEREIN
OR THE USE OR MAINTENANCE THEREOF OR ANY REPAIRS, SERVICING OR ADJUSTMENTS
THERETO OR ANY DELAY IN PROVIDING OR FAILURE TO PROVIDE ANY SERVICE OR
INTERRUPTION OR LOSS OF SERVICE OR USE THEREOF OR ANY LOSS OF BUSINESS, ALL OF
WHICH SHALL BE THE RISK AND RESPONSIBILITY OF LESSEE.

         All of Lessor's rights, privilege and indemnities contained in this
Section 13 shall survive the expiration or other termination of this Lease and
the rights, privileges and responsibilities contained herein are expressly made
for the benefit of, and shall be enforceable by Lessor, its successors and
assigns. The liability of Lessee to make indemnification payments pursuant to
this Section 13 shall, notwithstanding any expiration or termination of the
Lease, continue to exist until such indemnity payments are made by Lessee, in
full and received by Lessor. This Section 13 shall not apply to, and Lessee does
not indemnify Lessor against, any impositions or assessments or assessments for
federal, state or local income taxes or for taxes which are covered by Section 8
hereof.

SECTION 14. SUBLEASE; POSSESSION

         Lessee will not, without the prior written consent of Lessor, which
consent shall not be unreasonably withheld, assign any of its rights hereunder
or sublet or otherwise relinquish possession of the Airframe or any Engine or
install any Engine or Part, or permit any Engine or Part to be installed, on any
airframe other than the Airframe. In no event may the Aircraft be subleased to a
Person who is not a United States citizen or "United States Resident" within the
meaning of the Federal Aviation Act.

SECTION 15. TAX INDEMNIFICATION

         15.1 Lessee represents, warrants and covenants that (a) at the
commencement of this Lease, no Improvements, modifications or additions to the
Aircraft (other than ancillary items of equipment of a kind that customarily are
selected and furnished by purchasers or lessees of similar equipment) will be
required in order to render it complete for its intended use by Lessee, and (b)
at no time during the term of this Lease will Lessee take or omit to take, any
action not otherwise permitted by Lessor or the terms of this Lease, which will
result in the disqualification of the Aircraft or any portion thereof for, or
recapture of, all or any portion of Depreciation Deductions, and (c) at no time
during the term of this Lease will Lessee permit any Sublessee or Assignee to
take or omit to take any action (whether or not such act or omission is
otherwise permitted by Lessor or the terms of this Lease), which will result in
the disqualification of the Aircraft or any portion thereof for, or recapture
of, all or any portion of Depreciation Deductions. If as a result of a breach of
any representation, warranty or covenant contained in the immediately preceding
sentence (x) tax counsel of Lessor, in its reasonable opinion, shall determine
that Lessor is not entitled to claim on its Federal income tax return all or any
portion of the Tax Benefits with respect to the Aircraft, or (y) any such Tax
Benefit claimed on the federal income tax return of Lessor is disallowed or
adjusted by the Internal Revenue Service, or (2) any such Tax Benefit is
recomputed or recaptured by Lessor's tax counsel (any such determination,
disallowance, adjustment, recomputation or recapture being hereinafter called a
"loss"), THEN Lessee shall pay, upon demand, to Lessor, as an indemnity and as
additional Rent, such amount as shall cause Lessor's after-tax economic yields
and cash flows,


                                       14

<PAGE>   18



computed on the same assumptions including tax rates, as were utilized by lessor
in originally evaluating the transaction (such yields and flows hereinafter
called the "Net Economic Return") to equal the Net Economic Return that would
have been realized by Lessor if such loss had not occurred.

         15.2 Lessee hereby further represents, warrants and covenants that all
amounts includible in the gross income of Lessor with respect to the Aircraft,
and all deductions or credits allowable to Lessor with respect to the Aircraft,
will be treated as primarily derived from or allocable to sources within the
United States in each and every year throughout the term of this Lease. In the
event of a breach of the representation, warranty and covenant contained in the
immediately preceding sentence, if any item of income credit or deduction with
respect to the Aircraft shall not be treated as derived from, or allocable to,
sources within the United States for a given taxable year (any such event
hereinafter referred to as a "Foreign Loss"), then Lessee shall pay to Lessor as
an indemnity, on the next succeeding Rent Date, or in any event within thirty
(30) days after written demand to Lessee by Lessor, such amount as, after
deduction of all taxes required to be paid by Lessor in respect of the receipt
of such amounts under the laws of any Federal, state or local government or
taxing authority of the United States, shall equal the sum of: (a) the excess of
(x) the foreign tax credits which Lessor would have been entitled to for such
year had no such Foreign Loss occurred over (y) the foreign tax credits to which
Lessor was limited as a result of such year had no such Foreign Loss occurred
plus (b) the amount of any interest, penalties or additions to tax payable as a
result of such Foreign Loss.

         15.3 Lessee shall not be required to make any indemnity payment
pursuant to Section 15.1 or 15.2 to the extent that the loss giving rise to such
indemnity payment is a direct result of any event whereby Lessee is required to
pay by the terms of this Lease, and shall have paid in full, the Casualty Value.

         15.4 All of Lessor's rights, privileges and indemnities contained in
this Section 15 shall survive the expiration or other termination of this Lease
and the rights, privileges and indemnities contained herein are expressly made
for the benefit of, and shall be enforceable by, Lessor, its successor's and
assigns.

SECTION 16. EVENT OF DEFAULT

         The term Event of Default, whenever used herein, shall mean any of the
following events under this Lease (whatever the reason for such Event of Default
and whether it shall be voluntary or involuntary, or come about or be effected
by operation of law, or be pursuant to or in compliance with any judgment,
decree or order of any court or any order, rule or regulation or any
administrative or governmental body).

         16.1 Lessee shall fail to make any payment of Rent when due, and such
failure shall continue for more than ten (10) days after written notice thereof
from Lessor to Lessee; or

         16.2 Lessee shall fail to keep in full force and effect insurance
required under this Lease; or



                                       15

<PAGE>   19



         16.3 Lessee shall fail to perform or observe any covenant, condition or
agreement (other than that referred to in 16.1 or 16.2 above) required to be
performed or observed by it under this Lease or any agreement, document or
certificate delivered by Lessee in connection herewith, and such failure shall
continue for sixty (60) days after written notice thereof from Lessor to Lessee;
provided, however, if such failure is not reasonably susceptible to cure within
such sixty (60) day period, and Lessee has commenced to cure such failure within
said sixty (60) day period, Lessee shall have an additional period of time to
cure as may be required to effect such cure if Lessee continues to diligently
prosecute such cure to completion.

         16.4 Lessee shall or shall attempt to (except as expressly permitted by
the provisions of this Lease) remove, sell, transfer, encumber, part with
possession of, assign or sublet the Aircraft or any part thereof, use the
Aircraft for an illegal purpose, or permit the same to occur; or

         16.5 Lessee fails to pay its debts as they become due or files a
voluntary petition in bankruptcy or a voluntary petition or an answer seeking
reorganization in a proceeding under any bankruptcy laws (as now or hereafter in
effect) or an answer admitting the material allegations of a petition filed
against Lessee in any such proceeding, or Lessee by voluntary petition, answer
or consent, seeks relief under the provisions of any other now existing or
future bankruptcy or other similar law (other than a law which does not provide
for or permit the readjustment or alteration of Lessee's obligations hereunder)
providing for the reorganization or liquidation or corporations, or providing
for an agreement, composition, extension or adjustment with its creditors; or

         16.6 A petition against Lessee in a proceeding under applicable
bankruptcy laws or other insolvency laws (other than any law which does not
provide for or permit any readjustment or alteration of Lessee's obligations
hereunder in each case), as now or hereafter in effect, is filed and shall not
be withdrawn or dismissed within ninety (90) days thereafter, or if, under the
provisions of any law (other than any law which does not provide for or permit
any readjustment or alteration of Lessee's obligations hereunder in each case)
providing for reorganization or liquidation of corporations which may apply to
Lessee, any court of competent jurisdiction shall assume jurisdiction, custody
or control of Lessee or of any substantial part of its property and such
jurisdiction, custody or control shall remain in force relinquished, unstayed or
unterminated for a period of sixty (60) days; or

         16.7 Lessee (a) defaults on the payment of any obligation for borrowed
money, under any lease (whether or not capitalized) or for the deferred purchase
price of property, including interest thereon, beyond the period of grace, if
any, provided with respect thereto, or (b) defaults in the performance or
observance of any other term, condition or agreement contained in any such
obligation or in any agreement relating thereto, if the effect of either such
default is to cause, or permit the holder or holders of such obligation (or a
trustee on behalf of such holder or holders) to cause such obligation to become
due prior to its stated maturity or to realize upon any collateral given as
security therefor and such default results in material adverse change in the
financial condition of Lessee.

<PAGE>   20



SECTION 17. REMEDIES

         17.1 Upon the occurrence of any Event of Default and so long as the
same shall be continuing, Lessor may, at its option, declare this Lease to be in
default by written notice to such effect given to Lessee, and at any time
thereafter, Lessor may exercise one or more of the following remedies, as Lessor
in its sole discretion shall lawfully elect.

              (a) proceed by appropriate court action, either at law or in
equity, to enforce performance by Lessee of the applicable covenants of this
Lease or to recover damages for the breach thereof;

              (b) by notice in writing terminate this Lease, whereupon all
rights of Lessee to the use of the Aircraft or any part thereof shall absolutely
cease and terminate but Lessee shall remain liable as hereinafter provided; and
thereupon Lessee, if so requested by Lessor, shall at its expense promptly
return the Aircraft to the possession of Lessor at such place within the United
States (excluding Alaska and Hawaii) as Lessor shall designate and in the
condition required upon the return thereof pursuant to and in accordance with
the terms hereof, or Lessor, at its option, may enter upon the premises where
the Aircraft is located and take immediate possession of and remove the same
together with any Engines and Parts by summary proceedings or otherwise. Lessee
shall, without further demand, forthwith pay to Lessor an amount equal to any
unpaid Rent due and payable for all periods up to Rent Date immediately
following the date on which Lessor has declared this Lease to be in default,
plus, as liquidated damages for loss of a bargain and not as a penalty, an
amount equal to the Casualty Value of the Aircraft, computed as of the Rent Date
immediately preceding the date on which Lessor has declared this Lease to be in
default.

         17.2 Lessee shall be liable for all costs, charges and expenses
incurred by Lessor by reason of the occurrence of any Event of Default or the
exercise of Lessor's remedies with respect thereto.

         17.3 No remedy referred to herein is intended to be exclusive, but each
shall be cumulative and in addition to any other remedy referred to above or
otherwise available to Lessor at law or in equity. No express or implied waiver
by Lessor of any Default or Event of Default hereunder shall in anyway be, or be
construed to be, a waiver of any future or subsequent Default or Event of
Default. The failure or delay of Lessor in exercising any rights granted it
hereunder upon any occurrence of any of the contingencies set forth herein shall
not constitute a waiver of any such right upon the continuation or recurrence of
any such contingencies or similar contingencies and any single or partial
exercise of any particularly right by Lessor shall not exhaust the same or
constitute a waiver of any other right provided herein.

SECTION 18. NOTICES

         All communications and notices provided for herein shall be in writing
and shall become effective when deposited in the United States mail, with proper
postage for first-class mail, prepaid, addressed if to Lessor or Lessee at their
respective addresses set forth below or such other address as either party may
hereafter designate by written notice to the other:

such prohibition or unenforceability in any jurisdiction shall not invalidate or
render unenforceable such provision in any other jurisdiction. To the extent
permitted by applicable law, Lessee and Lessor for themselves hereby waives any
provision of law which renders any provision hereof prohibited or unenforceable
in any respect.

         20.4 Lessor's failure at any time or times to require strict
performance by Lessee of any of the terms or provisions hereof shall not waive,
affect or diminish any right of Lessor to demand strict compliance and
performance thereof, and any waiver of any default shall not waive or affect any
other or subsequent default. None of the conditions, provisions, and terms
contained herein shall be deemed to have been waived by any act or knowledge of
Lessor, its agents, officers, or employees. No waiver shall be effective unless
in writing specifically identifying such waiver and signed by Lessor.
