                      AMENDED AND RESTATED CREDIT AGREEMENT

         THIS AMENDED AND RESTATED CREDIT AGREEMENT is made as of the 7th day of
May, 2001, by and among BHA GROUP HOLDINGS, INC., a Delaware corporation
("Borrower"), BHA GROUP, INC., a Delaware corporation, and BHA TECHNOLOGIES,
INC., a Delaware corporation (each a "GUARANTOR" and together "GUARANTORS"), and
BANK OF AMERICA, N.A., a national banking association (the "BANK").

         WHEREAS, Borrower has requested the Bank to amend the existing Credit
Agreement among Borrower, Guarantors and the Bank dated September 30, 1999 (the
"EXISTING CREDIT AGREEMENT"), to permit borrowings in U.S. dollars or certain
alternate currencies, to continue the unsecured revolving line of credit
thereunder in the amount of $18,000,000, with a sublimit of $3,000,000 for
borrowings denominated in such alternate currencies, and to continue to make
available, on the request of Borrower, letters of credit to be applied against
the amount available under the revolving line of credit; and

         WHEREAS, the Bank has agreed to amend the Existing Credit Agreement and
to continue to make such credit and loans available to Borrower upon the terms
and conditions set forth herein;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements contained herein, the parties agree as follows:


                                    ARTICLE 1
                     DEFINITIONS AND INTERPRETIVE PROVISIONS

         1.1 DEFINITIONS. Certain terms used in this Agreement are defined
herein. Certain other terms are defined in Exhibit 1 attached hereto and
incorporated herein by this reference.

         1.2 INTERPRETIVE PROVISIONS. In addition to the interpretive provisions
set forth in Sections 1.3, 1.4 and 1.5, other interpretive provisions are in
Section 12.15 below and in other Articles of this Agreement.

         1.3 EXCHANGE RATES; ALTERNATIVE CURRENCY EQUIVALENTS. On each
Calculation Date, the Bank shall determine the exchange rate as of such
Calculation Date to be used for calculating relevant Dollar equivalent and
Alternative Currency equivalent amounts. The exchange rates so determined shall
become effective on such Calculation Date and shall for all purposes of this
Agreement (other than any provision expressly requiring the use of a current
exchange rate) be the exchange rates employed in converting any amounts between
the applicable currencies. Wherever in this Agreement in connection with a Loan,
a conversion or continuation of a Loan or the issuance of a Letter of Credit, an
amount (such as a required minimum or multiple amount) is expressed in Dollars
but such Loan or Letter of Credit is denominated in an Alternative

<PAGE>

Currency, such amount shall be the relevant Alternative Currency Equivalent of
such Dollar amount (rounded to the nearest 1,000 units of such Alternative
Currency), as determined by the Bank.

         1.4 REDENOMINATION OF CERTAIN ALTERNATIVE CURRENCIES. Each obligation
of Borrower to make a payment denominated in the national currency unit of any
member state of the European Union that adopts the Euro as its lawful currency
after the date hereof shall be redenominated into Euro at the time of such
adoption (in accordance with the EMU Legislation). If, in relation to the
currency of any such member state, the basis of accrual of interest expressed in
this Agreement in respect of that currency shall be inconsistent with any
convention or practice in the London interbank market for the basis of accrual
of interest in respect of the Euro, such expressed basis shall be replaced by
such convention or practice with effect from the date on which such member state
adopts the Euro as its lawful currency; provided that if any Loan in the
currency of such member state is outstanding immediately prior to such date,
such replacement shall take effect, with respect to such Loan, at the end of the
then current Interest Period. Each provision of this Agreement shall be subject
to such reasonable changes of construction as the Bank may from time to time
specify to be appropriate to reflect the adoption of the Euro by any member
state of the European Union and any relevant market conventions or practices
relating to the Euro.

                                    ARTICLE 2
                            REVOLVING LINE OF CREDIT

         2.1      AGREEMENT TO LEND.

                  (a) The Bank agrees, on the terms and subject to the
conditions set forth in this Agreement, to make loans (each a "REVOLVING LOAN")
to Borrower in Dollars or in one or more Alternative Currencies from time to
time before the Revolving Credit Termination Date, in such amounts as Borrower
shall request as provided in Section 4.8 hereof and to treat each draw under any
Letter of Credit as a Revolving Loan as provided in Section 3.1 below; provided,
however, that the Bank shall have no obligation to make a requested Revolving
Loan if, after the making of such Revolving Loan, (i) the aggregate unpaid
principal balance of all Revolving Loans, plus the aggregate undrawn amount
under all outstanding Letters of Credit would exceed the Revolving Credit
Commitment; (ii) the aggregate unpaid principal balance of all Revolving Loans
denominated in Alternative Currencies plus the aggregate undrawn amount under
all outstanding Letters of Credit denominated in Alternative Currencies would
exceed the Alternative Currency Sublimit; (iii) a Default or Event of Default
has occurred and is continuing; or (iv) the Loan requested is a LIBOR Rate Loan
or a EURIBOR Rate Loan and the requested LIBOR Rate or EURIBOR Rate election
would cause more than five (5) LIBOR Rate Loans or five (5) EURIBOR Rate Loans
to be outstanding. Borrower may terminate or reduce the unused portion of the
Revolving Credit Commitment at any time by giving notice to the Bank as provided
in Section 4.8 below, provided that any partial reduction shall be in an amount
of at least $1,000,000. Revolving Loans shall be used to pay existing
indebtedness to the Bank, for working



                                       2


<PAGE>


capital, for Acquisitions up to an aggregate of $3,000,000 during the term of
this Agreement, to purchase or redeem its own stock and for other corporate
purposes.

                  (b) If the aggregate principal indebtedness of Borrower under
the Revolving Note (as defined below), plus the aggregate undrawn amount under
all outstanding Letters of Credit, at any time exceeds the Revolving Credit
Commitment, Borrower shall immediately, without demand or notice, pay principal
under the Revolving Note so that the aggregate principal amount outstanding
thereunder, plus the aggregate undrawn amount under all outstanding Letters of
Credit, does not exceed the Revolving Credit Commitment.

         2.2 REVOLVING NOTE. The Revolving Loans shall be evidenced by and
repaid in accordance with a Revolving Credit Note executed by Borrower, in the
form of Exhibit 2.2 hereto, dated as of the date hereof, and payable to the
order of the Bank. Such note and any and all amendments, extensions,
modifications, renewals, reaffirmations, restatements, replacements and
substitutions thereof and therefor are herein referred to as the "REVOLVING
NOTE." Interest shall accrue on the unpaid principal balance of the Revolving
Note outstanding from time to time at a rate or rates determined as provided in
Section 4.3 below. The Revolving Note shall be paid in full on the Revolving
Credit Termination Date.


                                    ARTICLE 3
                             OTHER CREDIT FACILITIES

         3.1 LETTERS OF CREDIT. From time to time after the date hereof until
the Revolving Credit Termination Date, Borrower may apply to the Bank to issue,
in Dollars or in an Alternative Currency, or extend the expiration date of one
or more standby letters of credit for the account of Borrower (all such letters
of credit, together with all letters of credit issued by the Bank for the
account of Borrower outstanding on the date of this Agreement and all renewals
and extensions of any thereof, "LETTERS OF CREDIT"), each of which:

                  (a) shall be in a stated amount which, together with the
aggregate undrawn amount then outstanding under all Letters of Credit and the
principal amount then outstanding of all Revolving Loans, does not exceed the
Revolving Credit Commitment;

                  (b) shall, if it is denominated in an Alternative Currency, be
in a stated amount which, together with the aggregate undrawn amount then
outstanding under all Letters of Credit in Alternative Currencies and the
principal amount then outstanding of all Revolving Loans denominated in
Alternative Currencies, does not exceed the Alternative Currency Sublimit;

                  (c) shall, by its terms, not exceed a term of one year and
shall expire not later than the Revolving Credit Termination Date;

                                       3
<PAGE>

                  (d) shall require payment by Borrower of fees as described in
Section 5.2 hereof; and

                  (e) shall be issued, to the extent applicable, pursuant to the
Bank's  then-current standard form of application for letters of credit.

Borrower authorizes and directs the Bank to cause the repayment of each draw
under the Letters of Credit to be made immediately by charging such repayment
against the Revolving Note as a Prime Rate Loan; any draw under a Letter of
Credit denominated in an Alternative Currency shall be charged against the
Revolving Note as a Loan denominated in Dollars, with the Dollar equivalent
determined at the exchange rate in effect on the date of such draw.

         3.2 CONVERSION OF REVOLVING LOANS. Borrower may convert all or any
portion of the outstanding Revolving Loans to a loan with a fixed rate of
interest pursuant to an interest rate swap agreement or other similar agreement
that has terms and conditions acceptable to the Bank. The effective fixed rate
offered by the Bank will be based upon market conditions on the date of the
closing of any swap. Borrower may, at any time, prepay all or any portion of
such a converted loan, without premium or penalty; if Borrower prepays any such
loan, Borrower shall pay all fees and expenses associated with unwinding any
interest rate swap.


                                    ARTICLE 4
                TYPES OF LOANS; DISBURSEMENTS; INTEREST; PAYMENTS

         4.1 TYPES OF LOANS. All loans denominated in an Alternative Currency
shall be EURIBOR Rate Loans. Loans denominated in Dollars may, subject to the
terms and conditions of this Agreement, be Prime Rate Loans or LIBOR Rate Loans
(each being referred to as a "type" of Loan) as specified in the applicable
request for borrowing referred to in Section 4.8 hereof. Borrower may continue
Loans of one type as Loans of the same type or convert Dollar-denominated Loans
of one type into Loans of the other type, at any time or from time to time,
provided that if any LIBOR Rate Loan is converted on any day other than the last
day of the Interest Period for such Loan, Borrower shall pay all applicable fees
and amounts described in Section 5.3 below.

         4.2      LOAN DISBURSEMENT PROCEDURES.

                  (a) Loans shall be disbursed by the Bank upon request by
Borrower from time to time, in such amounts and in Dollars or an Alternative
Currency as is requested as provided in Section 4.8 below or in Section 3.1
above, subject to the limitations on the Bank's obligations to make Loans as set
forth in Section 2.1 and other provisions hereof. Subject to the terms of this
Agreement, Borrower may borrow, repay and reborrow Revolving Loans at any time
prior to the Revolving Credit Termination Date.

                                       4
<PAGE>

         Each request for a Loan shall be delivered to the Bank in writing or by
telex or facsimile transmission in the manner provided in Section 12.1 hereof,
or as otherwise agreed by the Bank, not later than 1:00 p.m., Kansas City,
Missouri time, on the date described in Section 4.8 below, which date shall be a
Business Day and shall be specified in the request (a "Disbursement Date"). The
Bank may rely and act upon any such request which is received from a person
believed by the Bank in good faith to be authorized to make such request on
behalf of Borrower. The Bank shall record in its records all Loans made by the
Bank to Borrower pursuant to this Agreement and all payments made on the Loans.

         4.3      INTEREST.

                  (a) Borrower shall pay to the Bank interest on the unpaid
principal amount of each Revolving Loan for the period commencing on and
including the date of such Loan to but excluding the date such Loan is paid in
full, at the following rates per annum:

         (i) during any period while such Loan is a Prime Rate Loan, the Prime
Rate (as in effect from time to time) less 1%; and

         (ii) during any period while such Loan is a LIBOR Rate Loan or an
EURIBOR Rate Loan, for each Interest Period relating thereto, the LIBOR Rate or
EURIBOR Rate for such Interest Period plus the Applicable Margin (as defined
below) in effect on the Disbursement Date, the date of conversion (with respect
to a LIBOR Rate Loan) or the date of continuation, as applicable and as adjusted
as provided in this Agreement. The Applicable Margin will be calculated and
adjusted, as shown below, on the first day of the month following the receipt by
the Bank of each quarterly Compliance Certificate; any change in the Applicable
Margin shall be effective with respect to Interest Periods beginning on or after
each such date. The interest rate with respect to each outstanding LIBOR Rate
Loan or EURIBOR Rate Loan shall not change during any Interest Period. The
"APPLICABLE MARGIN" will be as follows:

on and including the due date thereof until the same is paid in full and (ii)

any of the financial covenants set forth in Article 10 of this Agreement as
shown on and as of the last day of a fiscal quarter as reflected on any
Compliance Certificate.

                  (c) Accrued interest on each Loan shall be payable (i) in the
case of a Prime Rate Loan, on the last Business Day of each calendar quarter,
and (ii) in the case of a LIBOR Rate Loan or EURIBOR Rate Loan, on the last day
of each Interest Period therefor; provided that interest payable at the Default
Rate shall be payable, to the extent applicable, from time to time on demand of
the Bank.

                  (d) The Bank shall, as part of its interest statements, notify
Borrower of any change in the Prime Rate and shall, on the request of Borrower
at any time, notify Borrower of the LIBOR Rate and EURIBOR Rate then in effect.

         4.4 OPTIONAL AND MANDATORY PAYMENTS. Borrower shall have the right to
prepay the Loans in whole or in part at any time without premium or penalty,
subject to giving the Bank prior notice in accordance with the provisions of
Section 4.8 hereof, provided that (i) each such partial prepayment shall be in
the aggregate principal amount of not less than $100,000 with respect to Prime
Rate Loans and $500,000 with respect to LIBOR Rate Loans, and (ii) if any
prepayment of a LIBOR Rate Loan is made on any day other than the last day of
the Interest Period therefor, it may be prepaid only upon three (3) Business
Days prior notice to the Bank and Borrower shall pay to the Bank any applicable
fees and amounts described in Section 5.3(a) below. Amounts prepaid in respect
of Loans under this Section 4.4 may be reborrowed subject to the terms and
conditions hereof. Borrower shall make mandatory principal payments on the Loans
as provided in Section 2.1(b) above.

         4.5 PAYMENTS. Except as otherwise provided herein and subject to
Section 4.8 below, all payments of principal, interest, Fees, taxes, charges,
expenses and other items payable by Borrower hereunder and under the Note shall
be made in U.S. dollars or, with respect to principal and interest on Loans
denominated in an Alternative Currency, in such Alternative Currency (except
with respect to payment made by direct debit as provided in Section 4.6 below)
and shall be credited on the date of receipt by the Bank if received by the Bank
at its principal office in Kansas City, Missouri, in immediately available
funds, prior to 1:00 p.m., Kansas City, Missouri time, on a Business Day.
Payments made in funds which are not immediately available shall be credited
only when the funds are collected by the Bank, and payments received (whether
from Borrower in immediately available funds or through the collection of funds
which were not immediately available at the time payment was tendered by
Borrower) after 1:00 p.m. will be credited on the next Business Day. The Bank
reserves the right to apply all payments received by it from Borrower and
designated or authorized to be applied to a Note first to any Fees and other
charges then due to the Bank, then to accrued interest on such Note and then to
reduction of the principal balance of such Note, or such other order as the Bank
may determine in its sole discretion. The Bank shall also record in its records,
in accordance with customary accounting practice, all interest, Fees, taxes,



                                       6



<PAGE>



charges, expenses and other items properly chargeable to Borrower with respect
to the Loans, all payments received by the Bank for application to the
Obligations, and all other appropriate debits and credits. The Bank's records
shall constitute prima facie evidence of the amount of Obligations outstanding
from time to time.

         4.6      DIRECT DEBIT AND PRE-BILLING.

         (a) Borrower agrees that Bank will debit deposit account number
020100039303 or such other of Borrower's accounts with the Bank as designated in
writing by either Borrower (the "DESIGNATED ACCOUNT") on the date each payment
of principal, interest and all other Obligations, including the fees described
in Section 5.2 and fees, amounts and costs described in Section 5.3, become due
(the "DUE DATE"). Payments by direct debit with respect to Loans denominated in
an Alternative Currency will be converted to Dollars at the exchange rate in
effect at approximately 9:00 a.m. Central Time on the date of the debit. If the
Due Date is not a Business Day, the Designated Account will be debited on the
next Business Day.

         (b) Approximately 10 days prior to each Due Date, Bank will mail to
Borrower a statement of the amounts that will be due on that Due Date (the
"BILLED AMOUNT"). The calculation will be made on the assumption that no new
extensions of credit or payments will be made between the date of the billing
statement and the Due Date and that there will be no changes in the applicable
interest rate.

         (c) Bank will debit the Designated Account for the Billed Amount,
regardless of the actual amount due on that date (the "ACCRUED AMOUNT"). If the
Billed Amount debited to the Designated Account differs from the Accrued Amount,
the discrepancy will be treated as follows:

                  (i) If the Billed Amount is less than the Accrued Amount, the
Billed Amount for the following Due Date will be increased by the amount of the
discrepancy. Borrower will not be in default and an Event of Default will not
occur by reason of any such discrepancy.

                  (ii) If the Billed Amount is more than the Accrued Amount, the
Billed Amount for the following Due Date will be decreased by the amount of the
discrepancy.

         Regardless of any such discrepancy, interest will continue to accrue
based on the actual amount of principal outstanding without compounding. Bank
will not pay Borrower interest on any overpayment.

         (d) Borrower will maintain sufficient funds in the Designated Account
to cover each debit. If there are insufficient funds in the Designated Account
on the date Bank enters any debit authorized by this Agreement, the debit will
be reversed.

         (e) Borrower may terminate this direct debit arrangement at any time
by sending written notice to Bank.

                                       7
<PAGE>

         4.7 MINIMUM AMOUNTS. Each borrowing or conversion of Prime Rate Loans
shall be in an amount of at least $100,000 and each borrowing, conversion or
continuation of LIBOR Rate Loans and each borrowing or continuation of EURIBOR
Rate Loan shall be in an amount of or equivalent to $500,000 or a multiple of
$100,000 in excess thereof.

         4.8 CERTAIN REQUESTS AND NOTICES. Borrower will request borrowings and
give notice to the Bank of all terminations or reductions of Commitments,
conversions, continuations and prepayments of Loans and the duration of Interest
Periods, such requests and notices to be substantially in the form of Exhibits
4.8-A and 4.8-B hereto. Each such notice shall be irrevocable and shall be
effective only if received by the Bank not later than 1:00 p.m. Kansas City time
(i) on the Business Day prior to the effective date of the requested termination
or reduction of a Commitment, (ii) on the same date if it is a notice of a
borrowing or prepayment of a Prime Rate Loan (except that if such date is not a
Business Date, then on the next Business Day), or (iii) three (3) Business Days
prior to the requested effective date for a borrowing or prepayment of or
continuation as a LIBOR or EURIBOR Rate Loan or a conversion of a LIBOR Rate
Loan or any selection of Interest Period for a LIBOR or EURIBOR Rate Loan.

         Except as otherwise specifically provided in this Agreement, a LIBOR
Rate Loan may be converted to a Prime Rate Loan only on the last day of the
Interest Period for such Loan. A LIBOR Rate Loan or an EURIBOR Rate Loan may be
continued only on the last day of the Interest Period for such Loan. An EURIBOR
Rate Loan may not be converted.

         If Borrower fails to specify a currency for a borrowing, then the Loan
so requested shall be made in Dollars. If Borrower fails to specify a type
(whether Prime Rate or LIBOR Rate) of Dollar-denominated Loan in a request for a
borrowing or if Borrower fails to give a timely notice requesting a conversion
or continuation of a Dollar-denominated Loan, then the applicable Loan shall be
made or continued as, or converted to, a Prime Rate Loan. Any automatic
conversion to a Prime Rate Loan shall be effective as of the last day of the
Interest Period then in effect with respect to the applicable LIBOR Rate Loan.
In the case of a failure to timely request a continuation of a Loan denominated
in an Alternative Currency, such Loan shall be continued as a EURIBOR Rate Loan
in its original currency with an Interest Period of one month. If Borrower
requests a borrowing of or continuation of a LIBOR or EURIBOR Rate Loan or a
conversion of a Prime Rate Loan to a LIBOR Rate Loan but fails to specify an
Interest Period, Borrower will be deemed to have specified an Interest Period of
one month. No Loan may be converted into or continued as a Loan denominated in a
different currency but instead must be prepaid in the original currency of such
Loan and reborrowed in the other currency.

         For purposes of calculating the number of Business Days, the date the
notice is received shall be included if received not later than 1:00 p.m. Kansas
City time and excluded if received after 1:00 p.m. Kansas City time.

                          GUARANTIES; FEES; COLLATERAL

         5.1 GUARANTIES. Each of the Guarantors is delivering to the Bank, on
the date of this Agreement, a confirmation of its Guaranty Agreement. If
Borrower or any Subsidiary acquires or creates any subsidiary after the date of
this Agreement or if the Bank so requests with respect to any Subsidiary,
Borrower shall cause each such newly acquired or created Subsidiary and each
such other Subsidiary to become a Guarantor by causing it to deliver to the Bank
(i) a Guaranty Agreement executed by the Subsidiary in substantially the form
attached hereto as Exhibit 5.1 with such additional matters included therein as
may be required by the Bank (whether delivered at the Closing or thereafter,
each, a "LOAN GUARANTY"), (ii) if requested by Bank, an opinion of such
Subsidiary's counsel, satisfactory in form and substance to the Bank, as to the
enforceability of such Loan Guaranty and other matters required by the Bank;
such opinion shall be substantially the same as the opinion delivered with
respect to the initial Guarantors, with such additional matters included therein
as may be required by the Bank and shall include, if requested by the Bank, the
opinion of counsel from the Subsidiary's jurisdictions of organization and
operation, and (iii) copies of such Subsidiary's charter documents, certified by
the appropriate public official, and of its bylaws, certified by its secretary.

         5.2 UNUSED COMMITMENT AND LETTER OF CREDIT FEES. Borrower agrees to pay
a quarterly unused commitment fee equal to .25% of the Revolving Credit
Commitment less (i) the daily average outstanding balance of all Loans
denominated in Dollars, (ii) the aggregate undrawn amounts of all outstanding
Letters of Credit denominated in Dollars as of the Calculation Date, (iii) the
outstanding balance, in Dollars, as of the Calculation Date of all Loans
denominated in an Alternative Currency, using the exchange rate in effect on
such date, and (iv) the aggregate undrawn amount, in Dollars, of all outstanding
Letters of Credit denominated in an Alternative Currency as of the Calculation
Date, using the exchange rate in effect on such date. Borrower shall pay the
unused Commitment fees with respect to each quarter within 15 days after the end
of such quarter.

         Borrower agrees to pay an initial issuance fee on the date that each
standby Letter of Credit is issued in an amount equal to .125% of the amount of
such Letter of Credit and to pay the Bank's then standard fee for any renewals
and extensions of any Letter of Credit. Borrower also agrees to pay a fee in an
amount equal to the Applicable Margin rate per annum times the undrawn amount of
all outstanding Letters of Credit; such fee will be calculated and paid on last
business day of each fiscal quarter and shall be subject to appropriate
adjustment after the Bank's receipt of Borrower's Compliance Certificate
respecting such quarter.

         All fees shall be calculated on a 360-day year basis, if applicable.

         5.3      ADDITIONAL LIBOR AND EURIBOR RATE LOAN COSTS.

                  (a) Borrower shall pay to the Bank from time to time, upon
request of the Bank, (i) such amounts as the Bank may determine to be necessary
to compensate it for any Additional LIBOR and EURIBOR Rate Loan Costs respecting
Regulatory Changes and (ii) an administrative fee of $300 plus such amounts as
the Bank may determine to be necessary to compensate it for any loss, cost or
expense which the Bank incurs (including, without limitation, any loss, cost or
expense incurred by reason of the liquidation or re-employment of deposits, but
excluding loss of anticipated profits) that is attributable to (A) any payment,
prepayment or conversion of a LIBOR Rate Loan or EURIBOR Rate Loan made by
either Borrower for any reason on a date other than the last day of an Interest
Period for such Loan or (B) any failure by either Borrower for any reason
(including, without limitation, the failure of any condition specified in
Article 6 hereof to be satisfied) to borrow or continue or convert a LIBOR or
EURIBOR Rate Loan or convert a LIBOR Rate Loan on the date therefor specified in
the request for borrowing or notice given pursuant to Section 4.8 hereof. Such
compensation may include an amount equal to the excess, if any, of (i) the
amount of interest which would have accrued on the amount so prepaid, or not so
borrowed, converted or continued, for the period from the date of such
prepayment or of such failure to borrow, convert or continue to the last day of
the applicable Interest Period (or, in the case of a failure to borrow, convert
or continue, the Interest Period that would have commenced on the date of such
failure) in each case at the applicable rate of interest for such Loans provided
for herein (excluding, however, the Applicable Margin included therein, if any)
over (ii) the amount of interest (as reasonably determined by the Bank) which
would have accrued to the Bank on such amount by placing such amount on deposit
for a comparable period with leading banks in the interbank LIBOR market. The
covenants of Borrower set forth in this Section 5.3 shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder. The Bank will notify Borrower of any event which will entitle
the Bank to compensation pursuant to this Section 5.3 as promptly as practicable
after the Bank determines to require such compensation and will furnish Borrower
with a certificate setting forth in reasonable detail the basis and amount of
such compensation.

                  (b) Determinations by the Bank of the effect of any Regulatory
Change on its rate of return or cost of maintaining the LIBOR or EURIBOR Rate
Loans, on its obligation to make LIBOR or EURIBOR Rate Loans or on amounts
receivable by it in respect of the LIBOR or EURIBOR Rate Loans and
determinations of the amounts required to compensate such Bank under this
Section 5.3 shall be conclusive, provided that such determinations are made on a
reasonable basis and are set forth in reasonable detail in the certificates
referred to in Section 5.3(a) above.

                  (c) Anything herein to the contrary notwithstanding, if it
becomes unlawful for the Bank to honor its obligation to make or maintain LIBOR
or EURIBOR Rate Loans hereunder or if, on or prior to the determination of any
LIBOR Rate or EURIBOR Rate for any Interest Period, the Bank determines (which
determination shall be conclusive) that quotations of interest rates for the
relevant deposits referred to in the


                                       10

<PAGE>

definition of "LIBOR Rate" or "EURIBOR Rate" in Exhibit 1 hereto are not being
provided in the relevant amounts or for the relevant maturities for purposes of
determining rates of interest for such Loans, then the Bank shall give Borrower
prompt notice thereof, and, so long as such condition remains in effect, the
Bank shall be under no obligation to make or continue such Loans or to convert
Prime Rate Loans into LIBOR Rate Loans, and Borrower shall, on the last day(s)
of the then current Interest Period(s) for the outstanding LIBOR or EURIBOR Rate
Loans, either prepay such Loans or, with respect to LIBOR Rate Loans, convert
them into Prime Rate Loans.

         5.4 COLLATERAL. The Note will be unsecured. All assets of Borrower,
Guarantors and other Subsidiaries will be subject to the negative pledge set
forth in Section 10.9 below.

                                    ARTICLE 7
                         REPRESENTATIONS AND WARRANTIES

         Borrower, with respect to itself and with respect to each of the
Subsidiaries, and each of Guarantors, with respect to itself, represent and
warrant to the Bank that:

                                       12

<PAGE>

         7.1 CORPORATE EXISTENCE AND STANDING. Borrower is and each Subsidiary
is a corporation duly incorporated, validly existing and in good standing under
the laws of its jurisdiction of incorporation and has all requisite authority to
own its property and to carry on its business in each jurisdiction where the
failure to so qualify would have a material adverse effect on its business,
properties, assets, operations or condition (financial or otherwise).

         7.2 AUTHORIZATION AND VALIDITY. Borrower has and each Guarantor has the
corporate power and authority and legal right to execute and deliver the Loan
Documents to which it is a party and to perform its obligations thereunder. Such
execution and delivery have been duly authorized by proper proceedings, and the
Loan Documents constitute the legal, valid and binding obligations of Borrower
and the Guarantors, enforceable against them in accordance with their respective
terms.

         7.3 NO CONFLICT; GOVERNMENTAL CONSENT. The execution, delivery and
performance of the Loan Documents will not violate any law, rule, regulation,
order, writ, judgment, injunction, decree or award binding on Borrower or any
Subsidiaries, any provision of their respective articles or certificate of
incorporation, by-laws or other charter document, or the provisions of any
indenture, instrument or other written or oral agreement to which Borrower or
any Subsidiary is a party or is subject or by which Borrower or any Subsidiary
or any of their property is bound, or conflict therewith or constitute a default
thereunder, or result in the creation or imposition of any Lien in, of or on any
of their property pursuant to the terms of any such indenture, instrument or
agreement. No order, consent, approval, license, authorization or validation of,
or filing, recording or registration with, or exemption by, any Governmental
Authority is required to authorize or is required in connection with the
execution, delivery and performance of or the enforceability of any of the Loan
Documents.

         7.4      COMPLIANCE WITH LAWS; ENVIRONMENTAL AND SAFETY MATTERS.

                  (a) Borrower has and each Subsidiary has complied with all
applicable statutes, rules, regulations, orders and restrictions of any domestic
or foreign government or Governmental Authority having jurisdiction over the
conduct of its businesses or the ownership of its respective properties except
to the extent that such non-compliance will not have a material adverse effect
on the financial condition or business operations of Borrower, on a consolidated
or unconsolidated basis, or of either Guarantor.

                  (b) Borrower and the Subsidiaries have each, except as
disclosed in Schedule 7.4 hereto and to Borrower's and Guarantors' actual
knowledge, complied with all federal, national, state, local and other statutes,
ordinances, orders, judgments, rulings and regulations relating to environmental
pollution, environmental regulation or control, or employee health or safety,
except to the extent that such non-compliance will not have a material adverse
effect on their respective financial conditions or business operations; they
have not received any written notice of any failure so to comply except as
disclosed in Schedule 7.4 hereto; and their facilities do not treat, store or
dispose of any hazardous





                                       13



<PAGE>



wastes, hazardous substances, hazardous materials, toxic substances,
toxic pollutants or substances ("HAZARDOUS MATERIALS") similarly denominated, as
those terms or similar terms are used in RCRA, CERCLA, the Hazardous Materials
Transportation Act, the Toxic Substances Control Act, the Clean Air Act, the
Clean Water Act, the Occupational Safety and Health Act or any other state,
local or federal applicable law, ordinance, rule or regulation relating to
environmental pollution, environmental regulation or control or employee health
and safety ("ENVIRONMENTAL LAWS") in a quantity or manner that requires a
permit, registration, or another notification or authorization from a
Governmental Authority except for the treatment, storage, or disposal of
Hazardous Materials in a quantity or manner which, if in non-compliance with
Environmental Laws, would not have a material adverse effect on their respective
financial conditions or business operations except as disclosed in Schedule 7.4
hereto. The conduct of the business and the condition of the property of
Borrower and each of the Subsidiaries do not violate any Environmental Laws or
any judicial interpretation thereof relating primarily to the environment or
Hazardous Materials. Neither Borrower nor any Subsidiary is aware of any events,
conditions or circumstances involving environmental pollution or contamination
or employee health or safety that could reasonably be expected to result in
material liability on the part of Borrower or any Subsidiary.

         7.5 FINANCIAL STATEMENTS. Borrower has heretofore furnished to the Bank
its (a) consolidated balance sheet and related consolidated statements of
earnings and cash flows as of and for the fiscal year ended September 30, 2000,
and (b) an unaudited consolidated balance sheet and unaudited statements of
earnings and cash flows as of and for quarter ended March 31, 2001. Such
financial statements fairly state the consolidated financial condition and
results of operations of Borrower and the Subsidiaries as of such dates and for
such periods. Neither Borrower nor any of the Subsidiaries had on said date any
material (on a consolidated basis) contingent liabilities, material (on a
consolidated basis) liabilities for taxes, unusual forward or long-term
commitments or unrealized or anticipated losses from any unfavorable
commitments, except as referred to or reflected or provided for in said balance
sheet or the notes thereto as at said date. Such financial statements were
prepared in accordance with GAAP applied on a consistent basis. Since March 31,
2001, no material adverse change has occurred in the business, properties,
financial condition, prospects or results of operations of Borrower (on a
consolidated or unconsolidated basis) or of either Guarantor.

         7.6 OWNERSHIP OF PROPERTIES; COLLATERAL LIENS. Borrower has and each
Subsidiary has good title, free and clear of all Liens (other than those
permitted by Section 10.2 hereof), to all of the properties and assets reflected
in its financial statements as owned by it, and its interest in all other
properties and assets in or to which it has an interest as a lessee, licensee or
otherwise is free and clear of all Liens (other than those permitted under
Section 10.2 hereof).

         7.7 SUBSIDIARIES. Neither Borrower nor any Subsidiary has any
subsidiaries except as disclosed in Schedule 7.7. Except as described in
Schedule 7.7, all of the issued and outstanding shares of capital stock or other
ownership interests of each


                                       14


<PAGE>

Subsidiary, have been duly authorized and issued to Borrower or to a Subsidiary
and are fully paid and non-assessable, free and clear of all liens,
restrictions and rights.

         7.8 LITIGATION. All litigation, arbitration, mediation, governmental
investigations, proceedings or inquiries before any Governmental Authority,
arbitrator or mediator that are pending or, to the knowledge of any of its
officers, threatened against or affecting Borrower or any Subsidiary (other than
those covered by insurance, but only to the extent so covered) are not
reasonably expected to exceed, in the aggregate, $750,000.

         7.9 MATERIAL AGREEMENTS; LABOR MATTERS. Any agreement or instrument of
either Borrower or any Subsidiary that has or is likely to have a material
effect on the assets, prospects, business, operations, financial condition,
liabilities or capitalization of Borrower or Guarantor as a separate company or
of Borrower on a consolidated basis is referred to in this Section 7.9 as a
"MATERIAL CONTRACT." As of the date hereof, all of the Material Contracts are
listed on Schedule 7.9 hereto. Neither Borrower nor any Guarantor is in default
under any Material Contract in any manner that could materially and adversely
affect its assets, prospects, business, operations, financial condition,
liabilities or capitalization of or in any manner that could jeopardize its
right to require the performance, observance or fulfillment of any of the
obligations, covenants or conditions contained in any Material Contract. There
are no strikes or walkouts relating to any labor contracts with Borrower or any
Subsidiary pending or threatened, and no labor contracts are scheduled to expire
during the term of this Agreement, and no efforts are being made by any
employees to form a union or collectively bargain with Borrower or any
Subsidiary.

         7.10 INVESTMENT COMPANY ACT; PUBLIC UTILITY HOLDING COMPANY ACT.
Neither Borrower nor any Subsidiary is an "investment company" or a company
"controlled" by an "investment company," within the meaning of the Investment
Company Act of 1940, as amended, or a "holding company," a "subsidiary company"
of a "holding company" or an "affiliate" of a "holding company" or of a
"subsidiary company" of a "holding company," within the meaning of the Public
Utility Holding Company Act of 1935, as amended.

         7.11 TAXES. Borrower has and each Subsidiary has filed all United
States federal tax returns and all other tax returns which, to Borrower's or
either Guarantor's actual knowledge, are required to be filed and paid all taxes
due pursuant to said returns or pursuant to any assessment received by it,
including without limitation all federal and state withholding taxes and all
taxes required to be paid pursuant to applicable law, except such taxes, if any,
as are being contested in good faith, by appropriate proceedings and as to which
adequate charges, accruals and reserves have been set aside. No tax Liens have
been filed, and no claims are being asserted with respect to any such taxes,
except such tax Liens and claims that will not have a material adverse effect,
individually or in the aggregate, on the assets, business, operations or
financial condition of Borrower or either Guarantor, on a consolidated or
unconsolidated basis. The charges, accruals and reserves on the books of
Borrower, on a consolidated basis, in respect of any taxes or other governmental
charges are adequate.

         7.12 ACCURACY OF INFORMATION. No information, exhibit or report
furnished by Borrower or any Subsidiary to the Bank in connection with the
negotiation of the Loan Documents contained any material misstatement of fact or
omitted to state a material fact or any fact necessary to make the statements
contained therein not misleading.

         7.13 EMPLOYEE BENEFIT PLANS. Neither Borrower nor any Subsidiary
maintains, sponsors or contributes to any Defined Benefit Pension Plan.

         7.14 NO UNDISCLOSED DIVIDEND RESTRICTIONS. Except for limitations on
the payment of dividends under applicable corporate statutes, neither Borrower
nor any Subsidiary is subject to any agreement, covenant or understanding that
limits or restricts its ability to declare or pay dividends.

         7.15 ABSENCE OF DEFAULT OR EVENT OF DEFAULT. No Default and no Event of
Default has occurred and is continuing.

         7.16 DISCLOSURE. The pro forma financial information contained in
financial statements delivered to the Bank will be based upon good faith
estimates and assumptions believed by Borrower to be reasonable at the time
made. There is no fact known to Borrower (other than matters of a general
economic nature) that has had or could reasonably be expected to have a material
adverse effect and that has not been disclosed herein or in such other
documents, certificates and statements furnished to the Bank for use in
connection with the transactions contemplated by this Agreement.

         7.17 SOLVENCY. Based upon its financial and accounting records,
Borrower has and each Subsidiary has assets of a value that exceeds the amount
of its liabilities (excluding, for purposes of this representation, all
intercompany loans from liabilities). Borrower reasonably anticipates that it
and each of its Subsidiaries will be able to meet their respective debts as they
mature. Borrower and each Subsidiary have adequate capital to conduct the
business in which it is engaged.

         7.18 MARGIN REGULATIONS. Neither the making of the Loans hereunder, nor
the use of the proceeds thereof, will violate or be inconsistent with the
provisions of Regulation G, T, U or X of the Board of Governors of the Federal
Reserve System. No part of the proceeds of any Loan will be used, whether
directly or indirectly, and whether immediately, incidentally or ultimately, to
purchase or to extend credit to others for the purpose of purchasing or carrying
Margin Stock (as defined in said Regulation U).

         7.19 COPYRIGHTS, PATENTS AND OTHER RIGHTS. Borrower possesses and each
Subsidiary possesses all licenses, patents, patent rights and patent licenses,
trademarks, trademark rights and licenses, trade names, copyrights and all other
intellectual property rights which are required or desirable to conduct its
business as presently conducted; to the best of its knowledge, such rights do
not infringe on or conflict with the rights of any other Person; and Borrower
has and each Subsidiary has, and is current and in good



                                       16


<PAGE>


standing with respect to, all governmental approvals, permits and certificates
required to conduct its businesses as heretofore conducted.

         7.20 YEAR 2000 COMPLIANCE. Borrower has (a) initiated a review and
assessment of all areas within its and each of its Subsidiaries' business and
operations (including those affected by material suppliers and vendors) that
could be adversely affected by the risk that computer applications used by
Borrower or any Subsidiary or any of such suppliers and vendors may be unable to
recognize and properly perform date-sensitive functions involving certain dates
prior to and any date after December 31, 1999 (the "YEAR 2000 PROBLEM"), (b)
developed a plan and time line for addressing the Year 2000 Problem on a timely
basis, and (c) implemented that plan in accordance with that timetable. Borrower
reasonably believes that all computer applications (including those of its
suppliers and vendors) that are material to its or any of its Subsidiaries'
business and operations will on a timely basis be able to perform properly
date-sensitive functions for all dates before and after January 1, 2000 (that
is, be "YEAR 2000 COMPLIANT"), except to the extent that a failure to do so
could not reasonably be expected to have material adverse effect on the
financial condition or operations of Borrower, on a consolidated or
unconsolidated basis, or of either Guarantor.

directly or indirectly, with any person whereby it shall sell or transfer any
property, real or personal, used or useful in its business, whether now owned or
hereafter acquired, and thereafter rent or lease such property or other property
which it intends to use for substantially the same purpose or purposes as the
property being sold or transferred, provided that Borrower or any Subsidiary may
enter into any sale and lease-back transaction if (a) at the time of such
transaction no Default or Event of Default shall have occurred and be
continuing, (b) the proceeds from the sale of the subject property shall be at
least equal to its fair market value and (c) the subject property shall have

other property no longer required by or useful to it in connection with the
operation of its business;

                  (c) sales, assignments, transfers or other dispositions of

exceed $10,000,000 in the aggregate during the term of this Agreement;

                  (d) any Acquisition by Borrower, so long as not less than 15
days prior to the consummation of any Acquisition, Borrower shall provide to the
Bank, if the Bank so requests, the following information: pro forma financial
statements and projections and a pro forma Compliance Certificate, demonstrating
that Borrower will be, after giving effect to the Acquisition, in compliance
with each of the financial covenants set forth in Article 9 of this Agreement.
For purposes of such pro forma financial statements and pro forma compliance
certificate, to calculate the Borrower's compliance with the financial covenants
set forth in Article 9 hereof, after an acquisition of 100% of the stock or
assets of a company (an "ACQUIRED COMPANY"), the EBITDA of the Acquired Company,
based upon pro forma numbers acceptable to the Bank, from its last four rolling
quarters may be included to the extent that such numbers reflect cash flow from
assets fully transferred to Borrower as a result of the acquisition of the
Acquired Company, with adjustments for any transactions not in the ordinary
course of business. If Borrower acquires less than 100% of the stock or assets
of an Acquired Company, the Bank shall make a good faith determination of what
portion of such Acquired Company's EBITDA to include in the proforma financial
statements;

                  (e) any merger or consolidation of Borrower and any
Subsidiary, provided that Borrower is the surviving corporation thereof, or of
any Subsidiary with another Subsidiary or any sale or other transfer of assets
by a Subsidiary to Borrower.

assets to, or purchase or acquire any property or assets from, or otherwise
engage in any other transactions with, any of its Affiliates (other than any
Subsidiary as provided in Section 10.4 above), except that Borrower or a
Subsidiary may engage in any of the foregoing transactions in the ordinary
course of business at prices and on terms and conditions not less favorable to
it than could be obtained on an arm's-length basis from unrelated third parties.

         10.6 SUBSIDIARY DIVIDEND RESTRICTIONS. Not permit any Subsidiary to be
bound by or enter into any agreement, amendment, covenant, understanding or
revision to any agreement which prohibits or restricts the ability of any
Subsidiary to declare and pay dividends or make any other distribution to
Borrower.

         10.7 USE OF PROCEEDS. Not use any of the proceeds of the Loans (a) for
any purpose that entails a violation of, or that is inconsistent with, the
provisions of the regulations of the Board of Governors of the Federal Reserve
System, including without


                                       24

extensions of credit to, or investments (whether acquisitions of stock or
securities or otherwise) in, or acquire any assets of, any Persons, including,

shareholders, officers or employees (collectively, "INVESTMENTS"), other than:
