             ARTICLE II: THE TERM LOAN AND REVOLVING LOAN FACILITIES

                2.1 Term Loans.

                (A) Amounts of Term Loans. Subject to the terms and conditions
        set forth in this Agreement, each Term Loan Lender on the Closing Date
        severally and not jointly agrees to make on the Closing Date, a term
        loan, in Dollars, to the Borrower in an aggregate amount equal to such
        Lender's Term Loan Commitment (each individually, a "TERM LOAN" and,
        collectively, the "TERM LOANS"). All Term Loans shall be made by the
        Lenders on the Closing Date simultaneously and proportionately to their
        respective Term Loan Pro Rata Shares, it being understood that no Lender
        shall be responsible for any failure by any other Lender to perform its
        obligation to make any Term Loan hereunder nor shall the Term Loan
        Commitment of any Lender be increased or decreased as a result of any
        such failure.

                (B) Borrowing/Election Notice. The Borrower shall deliver to the
        Administrative Agent a Borrowing/Election Notice, signed by it, on the
        Closing Date. Such Borrowing/Election Notice shall specify (i) the
        aggregate amount of the Term Loans being requested and (ii) instructions

        shall initially be Floating Rate Loans and thereafter may be continued
        as Floating Rate Loans or converted into Eurodollar Rate Loans in the
        manner provided in Section 2.10 and subject to the other conditions and
        limitations therein set forth and set forth in this Article II. Any
        Borrowing/Election Notice given pursuant to this Section 2.1(B) shall be
        irrevocable.

                (C) Making of Term Loans. Promptly after receipt of the
        Borrowing/Election Notice under Section 2.1(B) in respect of the Term
        Loans, the Administrative Agent shall notify each Lender by telecopy, or
        other similar form of transmission, of the proposed Advance. Each Lender
        shall deposit an amount equal to its Term Loan Pro Rata Share of the
        Term Loans with the Administrative Agent at its office in Chicago,
        Illinois, in immediately available funds, on the Closing Date, as
        specified in the Borrowing/Election Notice. Subject to the fulfillment
        of the conditions precedent set forth in Sections 5.1 and 5.2, as
        applicable, the Administrative Agent shall make the proceeds of such
        amounts received by it available to the Borrower at the Administrative
        Agent's office in Chicago, Illinois on such date and shall disburse such
        proceeds in accordance with the Borrower's disbursement instructions set
        forth in such Borrowing/Election Notice. The failure of any Lender to
        deposit the amount described above with the Administrative Agent on such
        date shall not relieve any other Lender of its obligations hereunder to
        make its Term Loan on such date.

                (D) Repayment of the Term Loans.

                (i) The Term Loans shall be repaid in twenty (20) consecutive
        quarterly installments, payable on the last Business Day of each fiscal
        quarter of the Borrower, commencing on March 14, 2003 and continuing
        thereafter until the Term Loan Final Maturity Date, and the Term Loans
        shall be permanently reduced by the amount of each installment on the
        date payment thereof is made hereunder. The installments shall be in the
        aggregate amounts set forth below:

        Agent on the applicable Borrowing Date shall not relieve any other
        Lender of its obligations hereunder to make its Revolving Loan on such
        Borrowing Date.

        notice to the Administrative Agent and the Swing Line Bank. In addition,
        the Administrative Agent (i) may at any time in its sole discretion with
        respect to any outstanding Swing Line Loan, or (ii) shall on the fifth
        (5th) Business Day after the Borrowing Date of any Swing Line Loan,
        require each Lender (including the Swing Line Bank) to make a Revolving
        Loan in the amount of such Lender's Revolving Loan Pro Rata Share of
        such Swing Line Loan, for the purpose of repaying such Swing Line Loan.
        Not later than 2:00 p.m. (Chicago, Illinois time) on the date of any
        notice received pursuant to this Section 2.3(D), each Lender shall make
        available its required Revolving Loan or Revolving Loans, in funds
        immediately available in Chicago to the Administrative Agent at its
        address specified pursuant to Article XIV. Revolving Loans made pursuant
        to this Section 2.3(D) shall initially be Floating Rate Loans and
        thereafter may be continued as Floating Rate Loans or converted into
        Eurodollar Rate Loans in the manner provided in Section 2.10 and subject
        to the other conditions and limitations therein set forth and set forth
        in this Article II. Unless a Lender shall have notified the Swing Line
        Bank, prior to its making any Swing Line Loan, that any applicable
        condition precedent set forth in Sections 5.1 and 5.2, as applicable,
        had not then been satisfied, such Lender's obligation to make Revolving
        Loans pursuant to this Section 2.3(D) to repay Swing Line Loans shall be
        unconditional, continuing, irrevocable and absolute and shall not be
        affected by any circumstances, including, without limitation, (a) any
        set-off, counterclaim, recoupment, defense or other right which such
        Lender may have against the Administrative Agent, the Swing Line Bank,
        the Borrower or any other Person for any reason whatsoever; (b) the
        occurrence or continuance of any Default or Unmatured Default; (c) any
        adverse change in the condition (financial or otherwise) of the Borrower
        or any of its Subsidiaries or any other Person; (d) any breach of this
        Agreement by the Borrower or its Subsidiaries or any other Person; (e)
        any inability of the Borrower to satisfy the conditions precedent to
        borrowing set forth in this Agreement on the date upon which such
        Advance is to be made or such participating interest is to be purchased;
        (f) the termination of the Commitments hereunder; or (g) any other
        circumstance, happening or event whatsoever, whether or not similar to
        any of the foregoing. In the event that any Lender fails to make payment
        to the Administrative Agent of any amount due under this Section 2.3(D),
        the Administrative Agent shall be entitled to receive, retain and apply
        against such obligation the principal and interest otherwise payable to
        such Lender hereunder until the Administrative Agent receives such
        payment from such Lender or such obligation is otherwise fully
        satisfied. In addition to the foregoing, if for any reason any Lender
        fails to make payment to the Administrative Agent of any amount due
        under this Section 2.3(D), such Lender shall be deemed, at the option of
        the Administrative Agent, to have unconditionally and irrevocably
        purchased from the Swing Line Bank, without recourse or warranty, an
        undivided interest and participation in the applicable


                                       35
<PAGE>

        Swing Line Loan in the amount of such Revolving Loan, and such interest
        and participation may be recovered from such Lender together with
        interest thereon at the Federal Funds Effective Rate for each day during
        the period commencing on the date of demand and ending on the date such
        amount is received. On the Commitment Termination Date, the Borrower
        shall repay in full the outstanding principal balance of the Swing Line
        Loans.

                2.4 Rate Options for all Advances; Maximum Interest Periods. The
Swing Line Loans shall be Floating Rate Advances at all times. The Revolving
Loans and Term Loans may be Floating Rate Advances or Eurodollar Rate Advances,
or a combination thereof, selected by the Borrower in accordance with Section
2.10; provided, however, notwithstanding anything herein to the contrary, the
Borrower may not select Interest Periods for Eurodollar Rate Advances made
during the Syndication Period which exceed fourteen (14) days and the Interest
Periods with respect to all such Eurodollar Rate Advances made during the
Syndication Period shall be required to expire on the same date. The Borrower
may select, in accordance with Section 2.10, Rate Options and Interest Periods
applicable to portions of the Revolving Loans and the Term Loans; provided that
there shall be no more than five (5) Interest Periods in effect with respect to
all Eurodollar Rate Loans at any time.

                2.5 Optional Payments; Mandatory Prepayments.

                (A) Optional Payments. The Borrower may from time to time and at
        any time after notice delivered to the Administrative Agent no later
        than 2:00 p.m. (Chicago, Illinois time) on such date of repayment or
        prepayment, repay or prepay, without penalty or premium, all or any part
        of outstanding Floating Rate Advances in an aggregate minimum amount of
        $500,000 and in integral multiples of $100,000 in excess thereof.
        Eurodollar Rate Advances may be voluntarily repaid or prepaid prior to
        the last day of the applicable Interest Period, subject to the
        indemnification provisions contained in Section 4.4, in an aggregate
        minimum amount of $100,000 and in integral multiples of $100,000 in
        excess thereof (unless such Eurodollar Rate Advance is repaid or prepaid
        in whole); provided, that the Borrower may not so prepay Eurodollar Rate
        Advances unless it shall have provided at least three (3) Business Days'
        prior written notice to the Administrative Agent of such prepayment.

                (B) Mandatory Prepayments.

                (i) Mandatory Prepayments of Term Loans.

                        (a) Asset Sales and Loss Proceeds. Upon (1) the
                consummation of any Asset Sale (other than any Asset Sale
                permitted under clauses (i) through (iii) of Section 7.3(b)) by
                the Borrower or any Subsidiary of the Borrower, except to the
                extent that the Net Cash Proceeds of such Asset Sale, when
                combined with the Net Cash Proceeds of all such Asset Sales
                during the immediately preceding twelve-month period, do not
                exceed $1,000,000, for any such Asset Sale or series of related
                Asset Sales or (2) the receipt by Borrower or any of its
                Subsidiaries of proceeds from insurance in connection with any
                property loss or casualty (other than proceeds received in
                respect of business interruption insurance) ("LOSS


                                       36
<PAGE>

                PROCEEDS"), except to the extent that such Loss Proceeds, when
                combined with all other Loss Proceeds received during the then
                current fiscal year, do not exceed $500,000, and, in each case,
                except as provided in the second sentence of this Section
                2.5(B)(i)(a), within thirty-five (35) days after the Borrower's
                or any of its Subsidiaries' (x) receipt of any Net Cash Proceeds
                from any such Asset Sale or any such Loss Proceeds, or (y)
                conversion to cash or Cash Equivalents of non-cash proceeds
                (whether principal or interest and including securities, release
                of escrow arrangements or lease payments) received from any
                Asset Sale, the Borrower shall make a mandatory prepayment of
                the Obligations in an amount equal to one hundred percent (100%)
                of such Net Cash Proceeds or such Loss Proceeds or such proceeds
                converted from non-cash to cash or Cash Equivalents. In the
                event that the Borrower shall have given the Administrative
                Agent written notice within thirty (30) days after an Asset Sale
                or event giving rise to such Loss Proceeds of its intention to
                replace the assets or use such Net Cash Proceeds or Loss
                Proceeds, as applicable, to acquire other like-kind assets
                (which shall include, without limitation, assets acquired
                pursuant to a Permitted Acquisition) within six (6) months
                following such Asset Sale or the receipt of such Loss Proceeds,
                as applicable, then such Net Cash Proceeds or Loss Proceeds
                shall not be subject to the provisions of the first sentence of
                this Section 2.5(B)(i)(a) unless and to the extent that such
                applicable period shall have expired without such replacement
                having been made.


                        (b) Excess Cash Flow. Simultaneously with the delivery
                of the annual audited financial statements required to be
                delivered pursuant to Section 7.1(A)(iii) for each fiscal year
                beginning with the fiscal year ending September 30, 2003, the
                Borrower shall calculate Excess Cash Flow for such fiscal year
                and shall make a mandatory prepayment of the Obligations,
                payable not later than thirty (30) days after the date such
                financial statements are required to be delivered pursuant to
                Section 7.1(A)(iii), in an amount equal to seventy-five percent
                (75%) of such Excess Cash Flow.

                        (c) Financings. With the exception of the issuance of
                Capital Stock in connection with any Incentive Arrangement, or
                the refinancing of the Subordinated Notes to the extent
                otherwise permitted hereunder, upon the consummation of any
                Financing by the Borrower or any Subsidiary of the Borrower,
                within three (3) Business Days after the Borrower's or any of
                its Subsidiaries' receipt of any Net Cash Proceeds from such
                Financing, the Borrower shall make a mandatory prepayment of the
                Obligations in an amount equal to one hundred percent (100%) of
                such Net Cash Proceeds.

                        (d) No Consent. Nothing in this Section 2.5(B)(i) shall
                be construed to constitute the Lenders' consent to any
                transaction referred to in clause (a) or (c) above which is
                expressly prohibited by the terms of this Agreement.

                        (e) Application of Designated Prepayments. Each
                mandatory prepayment required by clauses (a), (b) and (c) of
                this Section 2.5(B)(i) shall be


                                       37
<PAGE>

                referred to herein as a "Designated Prepayment." Designated
                Prepayments shall be allocated and applied to the Obligations as
                follows:

                                (1) the amount of each Designated Prepayment
                        shall be applied to outstanding accrued interest and
                        then ratably to each of the then remaining installments
                        payable under the Term Loans; and

                                (2) following the payment in full of the Term
                        Loans, the amount of each Designated Prepayment shall be
                        applied to repay Revolving Loans (and may, if requested
                        by the Borrower, reduce the Revolving Loan Commitments)
                        and following the payment in full of the Revolving
                        Loans, the amount of each Designated Prepayment shall be
                        applied first to interest on the Reimbursement
                        Obligations, then to principal on the Reimbursement
                        Obligations, then to fees on account of Letters of
                        Credit and then, to the extent any L/C Obligations are
                        contingent, deposited with the Administrative Agent as
                        cash collateral in respect of such L/C Obligations.

                (ii) Mandatory Prepayments of Obligations. In addition to
        repayments under Section 2.5(B)(i)(e)(2), if at any time and for any
        reason (x) the amount of the Revolving Credit Obligations are greater
        than the Maximum Revolving Credit Amount or (b) the amount of the
        Revolving Credit Obligations plus the aggregate outstanding principal
        amount of the Term Loans are greater than the Borrowing Base (Senior
        Debt) as in effect at such time, the Borrower shall immediately make a
        mandatory prepayment of the Obligations in an amount equal to such
        excess.

                (iii) Application of Prepayments. On the date any Designated
        Prepayments or any prepayment under clause (ii) above is received by the
        Administrative Agent, such prepayment shall be applied first to Floating
        Rate Loans and to any Eurodollar Rate Loans maturing on such date and
        then to subsequently maturing Eurodollar Rate Loans in order of
        maturity.

                2.6 Reduction of Commitments. The Borrower may permanently
reduce the Aggregate Revolving Loan Commitment in whole, or in part ratably
among the Lenders, in an aggregate minimum amount of $1,000,000 with respect to
each such Commitment and integral multiples of $500,000 in excess of that amount
with respect to each such Commitment (unless the Aggregate Revolving Loan
Commitment is reduced in whole), upon at least five (5) Business Days' prior
written notice to the Administrative Agent, which notice shall specify the
amount of any such reduction; provided, however, that the amount of the
Aggregate Revolving Loan Commitment may not be reduced below the aggregate
principal amount of the outstanding Revolving Credit Obligations. All accrued
commitment fees shall be payable on the effective date of any termination of all
or any part of the obligations of the Lenders to make Loans hereunder.

                2.7 Method of Borrowing. Not later than 2:00 p.m. (Chicago,
Illinois time) on each Borrowing Date, each Lender shall make available its
Revolving Loan or Term Loan, in immediately available funds in Dollars to the
Administrative Agent at its address specified


                                       38
<PAGE>

pursuant to Article XIV. The Administrative Agent will promptly make the funds
so received from the Lenders available to the Borrower at the Administrative
Agent's aforesaid address.

                2.8 Method of Selecting Types and Interest Periods for Advances.
The Borrower shall select the Type of Advance and, in the case of each
Eurodollar Rate Advance and the Interest Period applicable to each Advance from
time to time. The Borrower shall give the Administrative Agent irrevocable
notice in substantially the form of Exhibit B hereto (a "BORROWING/ELECTION
NOTICE") not later than 12:00 noon (Chicago, Illinois time) (A) on or before the
Borrowing Date of each Floating Rate Advance, and (B) three (3) Business Days
before the Borrowing Date for each Eurodollar Rate Advance, specifying: (i) the
Borrowing Date (which shall be a Business Day) of such Advance; (ii) the
aggregate amount of such Advance; (iii) the Type of Advance selected; and (iv)
in the case of each Eurodollar Rate Advance, the Interest Period applicable
thereto. The Borrower shall select Interest Periods so that, to the best of its
knowledge, it will not be necessary to prepay all or any portion of any
Eurodollar Rate Loan prior to the last day of the applicable Interest Period in
order to make mandatory prepayments as required pursuant to the terms hereof.
With respect to the Term Loans, the Borrower may not select an Interest Period
that ends after the Term Loan Final Maturity Date. With respect to the Revolving
Loans, the Borrower may not select an Interest Period that ends after the
Revolving Loan Termination Date. Each Floating Rate Advance and all Obligations
other than Loans shall bear interest from and including the date of the making
of such Advance, in the case of Loans, and the date such Obligation is due and
owing in the case of such other Obligations, to (but not including) the date of
repayment thereof at the Floating Rate, changing when and as such Floating Rate
changes. Changes in the rate of interest on that portion of any Advance
maintained as a Floating Rate Loan will take effect simultaneously with each
change in the Alternate Base Rate. Each Eurodollar Rate Advance shall bear
interest from and including the first day of the Interest Period applicable
thereto to (but not including) the last day of such Interest Period at the
interest rate determined as applicable to such Eurodollar Rate Advance and shall
change as and when the Applicable Eurodollar Margin changes.

                2.9 Minimum Amount of Each Advance. Each Floating Rate Advance
(other than an Advance to repay Swing Line Loans or a Reimbursement Obligation)
shall be in the minimum amount of $1,000,000 and in multiples of $500,000 if in
excess thereof, provided, however, that any Floating Rate Advance may be in the
amount of the unused Aggregate Revolving Loan Commitment. Each Eurodollar Rate
Advance shall be in the minimum amount of $2,500,000 and in multiples of
$500,000 if in excess thereof.

                2.10 Method of Selecting Types and Interest Periods for
Conversion and Continuation of Advances.

                (A) Right to Convert. The Borrower may elect from time to time,
        subject to the provisions of Section 2.4 and this Section 2.10, to
        convert all or any part of a Loan of any Type into any other Type or
        Types of Loans; provided that any conversion of any Eurodollar Rate
        Advance shall be made on, and only on, the last day of the Interest
        Period applicable thereto.

                (B) Automatic Conversion and Continuation. Floating Rate Loans
        shall continue as Floating Rate Loans unless and until such Floating
        Rate Loans are converted


                                       39
<PAGE>

        into Eurodollar Rate Loans. Eurodollar Rate Loans shall continue as
        Eurodollar Rate Loans until the end of the then applicable Interest
        Period therefor, at which time such Eurodollar Rate Loans shall be
        automatically converted into Floating Rate Loans unless the Borrower
        shall have given the Administrative Agent notice in accordance with
        Section 2.10(D) requesting that, at the end of such Interest Period,
        such Eurodollar Rate Loans continue as a Eurodollar Rate Loan.

                (C) No Conversion Post-Default or Post-Unmatured Default.
        Notwithstanding anything to the contrary contained in Section 2.10(A) or
        Section 2.10(B), no Loan may be converted into or continued as a
        Eurodollar Rate Loan when any Default or Unmatured Default has occurred
        and is continuing, except with the consent of the Required Lenders.

                (D) Borrowing/Election Notice. The Borrower shall give the
        Administrative Agent irrevocable notice (a "BORROWING/ELECTION NOTICE")
        of each conversion of a Floating Rate Loan into a Eurodollar Rate Loan
        or continuation of a Eurodollar Rate Loan not later than 12:00 noon
        (Chicago, Illinois time) three (3) Business Days prior to the date of
        the requested conversion or continuation, specifying: (1) the requested
        date (which shall be a Business Day) of such conversion or continuation;
        (2) the amount and Type of the Loan to be converted or continued; and
        (3) the amount of Eurodollar Rate Loan(s) into which such Loan is to be
        converted or continued and the duration of the Interest Period
        applicable thereto.

                2.11 Default Rate. After the occurrence and during the
continuance of a Default, at the option of the Administrative Agent or at the
direction of the Required Lenders, and in any event automatically upon the
occurrence of a Default under Section 8.1(F), (G) or (I), the interest rate(s)
applicable to (i) all Eurodollar Rate Advances shall be calculated based on the
highest Applicable Eurodollar Margin under the pricing grid set forth in Section
2.15(D)(ii) plus two percent (2.00%) per annum, (ii) all Floating Rate Advances
and all other Obligations and all other fees (including the fees payable under
Section 3.8 with respect to Letters of Credit) shall be calculated based on the
highest Applicable Floating Rate Margins under the pricing grid set forth in
Section 2.15(D)(ii) plus two percent (2.00%) per annum.

                2.12 Method of Payment; Collection Account Arrangements.

                (A) Method of Payment. All payments of principal, interest,
        fees, reimbursements, commissions, L/C Obligations and other Obligations
        hereunder shall be made, without setoff, deduction or counterclaim
        (unless indicated otherwise in Section 2.15(E)), in immediately
        available funds to the Administrative Agent at the Administrative
        Agent's address specified pursuant to Article XIV, or at any other
        Lending Installation of the Administrative Agent specified in writing by
        the Administrative Agent to the Borrower, by 1:00 p.m. (Chicago,
        Illinois time) on the date when due and shall be made ratably among the
        Lenders (unless such amount is not to be shared ratably in accordance
        with the terms hereof). Each payment delivered to the Administrative
        Agent for the account of any Lender shall be delivered promptly by the
        Administrative Agent to such Lender in the same type of funds that the
        Administrative Agent received at its address specified pursuant to
        Article XIV or at any Lending


                                       40
<PAGE>

        Installation specified in a notice received by the Administrative Agent
        from such Lender. The Borrower authorizes the Administrative Agent to
        charge the account of the Borrower maintained with LaSalle for each
        payment of principal, interest, fees, commissions and L/C Obligations as
        it becomes due hereunder. Each reference to the Administrative Agent in
        this Section 2.12 shall also be deemed to refer, and shall apply
        equally, to each Issuing Bank, in the case of payments required to be
        made by the Borrower to any Issuing Bank pursuant to Article III.

                (B) Cash Management Arrangements. On or prior to the Closing
        Date, the Borrower shall have entered into and shall thereafter maintain
        cash management arrangements acceptable to the Administrative Agent and
        the Borrower.

                2.13 Evidence of Debt.

                (A) Loan Account. Each Lender shall maintain in accordance with
        its usual practice an account or accounts (a "LOAN ACCOUNT") evidencing
        the indebtedness of the Borrower to such Lender owing to such Lender
        from time to time, including the amounts of principal and interest
        payable and paid to such Lender from time to time hereunder.

                (B) Register. The Register maintained by the Administrative
        Agent pursuant to Section 13.3(C) shall include a control account, and a
        subsidiary account for each Lender, in which accounts (taken together)
        shall be recorded (i) the date and the amount of each Loan made
        hereunder, the Type thereof and the Interest Period, if any, applicable
        thereto, (ii) the amount of any principal or interest due and payable or
        to become due and payable from the Borrower to each Lender hereunder,
        (iii) the effective date and amount of each Assignment Agreement
        delivered to and accepted by it and the parties thereto pursuant to
        Section 13.3, (iv) the amount of any sum received by the Administrative
        Agent hereunder for the account of the Lenders and each Lender's share
        thereof, and (v) all other appropriate debits and credits as provided in
        this Agreement, including, without limitation, all fees, charges,
        expenses and interest.

                (C) Entries in Loan Account and Register. The entries made in
        the Loan Account, the Register and the other accounts maintained
        pursuant to clauses (A) or (B) of this Section shall be conclusive and
        binding for all purposes, absent manifest error, unless the Borrower
        objects to information contained in the Loan Accounts, the Register or
        the other accounts within thirty (30) days of the Borrower's receipt of
        such information; provided that the failure of any Lender or the
        Administrative Agent to maintain such accounts or any error therein
        shall not in any manner affect the obligation of the Borrower to repay
        the Loans in accordance with the terms of this Agreement.

                (D) Notes Issued Upon Request. Any Lender may request that the
        Revolving Loans or Term Loans made, or to be made, by it each be
        evidenced by a promissory note in substantially the forms of Exhibit K-1
        or K-2, respectively, to evidence such Lender's Revolving Loans or Term
        Loans, as applicable. In such event, the Borrower shall prepare, execute
        and deliver to such Lender a promissory note for such Loans payable to
        the order of such Lender and in a form approved by the Administrative
        Agent and consistent with the terms of this Agreement. Thereafter, the
        Loans evidenced by such


                                       41
<PAGE>

        promissory note and interest thereon shall at all times (including after
        assignment pursuant to Section 13.3) be represented by one or more
        promissory notes in such form payable to the order of the payee named
        therein.

                2.14 Telephonic Notices. The Borrower authorizes the Lenders and
the Administrative Agent to extend, convert or continue Advances, effect
selections of Types of Advances and to transfer funds based on telephonic
notices made by any person or persons the Administrative Agent or any Lender in
good faith believes to be a Borrower Representative. The Borrower agrees to
deliver promptly to the Administrative Agent a written confirmation, signed by
an Authorized Officer, if such confirmation is requested by the Administrative
Agent or any Lender, of each telephonic notice. In case of disagreement
concerning such notices, if the Administrative Agent has recorded telephonic
borrowing notices, such recordings will be made available to the Borrower upon
its request therefor.

                2.15 Promise to Pay; Interest and Commitment Fees; Interest
Payment Dates; Interest and Fee Basis; Taxes; Loan and Control Accounts.

                (A) Promise to Pay. All Revolving Loans shall be paid in full by
        the Borrower on the earlier of (i) the Commitment Termination Date and
        (ii) the Facility Termination Date. All Term Loans shall be paid in full
        by the Borrower on the earlier of the (i) Term Loan Final Maturity Date
        and (ii) the Facility Termination Date. The Borrower unconditionally
        promises to pay when due the principal amount of each Loan and all other
        Obligations incurred by it, and to pay all unpaid interest accrued
        thereon, in accordance with the terms of this Agreement and the other
        Loan Documents.

                (B) Interest Payment Dates. Interest accrued on each Floating
        Rate Loan shall be payable on each Payment Date, commencing with the
        first such date to occur after the date hereof, upon any prepayment
        whether by acceleration or otherwise, and at maturity (whether by
        acceleration or otherwise). Interest accrued on each Eurodollar Rate
        Loan shall be payable on the last day of its applicable Interest Period,
        on any date on which the Eurodollar Rate Loan is prepaid, whether by
        acceleration or otherwise, and at maturity. Interest accrued on each
        Eurodollar Rate Loan having an Interest Period longer than three months
        shall also be payable on the last day of each three-month interval
        during such Interest Period. Interest accrued on the principal balance
        of all other Obligations shall be payable in arrears (i) on each Payment
        Date, commencing on the first such day following the incurrence of such
        Obligation, (ii) upon repayment thereof in full or in part, and (iii) if
        not theretofore paid in full, at the time such other Obligation becomes
        due and payable (whether by acceleration or otherwise).

                (C) Commitment Fees; Fee Letter.

                (i) The Borrower shall pay to the Administrative Agent, for the
        account of the Lenders in accordance with their Revolving Loan Pro Rata
        Shares, from and after the Closing Date until the date on which the
        Aggregate Revolving Loan Commitment shall be terminated in whole, a
        commitment fee accruing at the rate of the then Applicable Commitment
        Fee Percentage, multiplied by the average daily amount by which (A) the
        Aggregate Revolving Loan Commitment exceeds (B) the Revolving


                                       42
<PAGE>

        Credit Obligations (excluding the outstanding principal amount of the
        Swing Line Loans). All such commitment fees payable under this clause
        (C) shall be payable quarterly in arrears on each Payment Date occurring
        after the Closing Date (with the first such payment being calculated for
        the period from the Closing Date and ending on the first Payment Date
        thereafter), and, in addition, on any date on which the Aggregate
        Revolving Loan Commitment shall be terminated in whole.

                (ii) The Borrower agrees to pay to the Administrative Agent for
        the sole account of the Administrative Agent and the Arranger (unless
        otherwise agreed between the Administrative Agent and the Arranger and
        any Lender) the fees set forth in the letter agreement between the
        Administrative Agent and the Borrower, dated May 23, 2002, payable at
        the times and in the amounts set forth therein.

                (D) Interest and Fee Basis; Applicable Floating Rate Margins,
        Applicable Eurodollar Margins and Applicable Commitment Fee Percentage.

                (i) Interest on all Eurodollar Rate Loans and on all fees shall
        be calculated for actual days elapsed on the basis of a 360-day year.
        Interest on all Floating Rate Loans shall be calculated for actual days
        elapsed on the basis of a 365-, or when appropriate 366-, day year.
        Interest shall be payable for the day an Obligation is incurred but not
        for the day of any payment on the amount paid if payment is received
        prior to 2:00 p.m. (Chicago, Illinois time) at the place of payment. If
        any payment of principal of or interest on a Loan or any payment of any
        other Obligations shall become due on a day which is not a Business Day,
        such payment shall be made on the next succeeding Business Day and, in
        the case of a principal payment, such extension of time shall be
        included in computing interest, fees and commissions in connection with
        such payment.

                (ii) The Applicable Floating Rate Margins, Applicable Eurodollar
        Margins and Applicable Commitment Fee Percentage shall be determined
        from time to time by reference to the tables set forth below, (a) in the
        case of the Applicable Floating Rate Margins and Applicable Eurodollar
        Margins, on the basis of the then applicable Leverage Ratio as described
        in this Section 2.15(D)(ii), and (b) in the case of the Applicable
        Commitment Fee Percentage, on the basis of the then outstanding amount
        of the Revolving Credit Obligations as a percentage of the Aggregate
        Revolving Loan Commitment in effect at such time:

                For purposes of this Section 2.15(D)(ii), the Leverage Ratio
shall be calculated as provided in Section 7.4(B). Upon receipt of the financial
statements delivered pursuant to Sections 7.1(A)(ii) and (iii), as applicable,
the Applicable Floating Rate Margins and Applicable Eurodollar Margins shall be
adjusted, such adjustment being effective five (5) Business Days following the
Administrative Agent's receipt of such financial statements and the compliance
certificate required to be delivered in connection therewith pursuant to Section
7.1(A)(iv); provided, that if the Borrower shall not have timely delivered its
financial statements in accordance with Section 7.1(A)(ii) or (iii), as
applicable, then commencing on the date upon which such financial statements
should have been delivered and continuing until five (5) Business Days following
the date such financial statements are actually delivered, the Applicable
Floating Rate Margins and Applicable Eurodollar Margins shall be the Applicable
Floating Rate Margins and Applicable Eurodollar Margins, as applicable, under
the pricing grid set forth in this Section 2.15(D)(ii) in effect on the date
such financial statements were required to be delivered under Section 7.1(A)(ii)
or (iii), as applicable; provided that if upon delivery of such financial
statements any increase of the Applicable Floating Rate Margins or the
Applicable Eurodollar Rate Margins shall be required under this Section 2.15(D),
such adjustment shall be made retroactively to the date such financial
statements were initially required to be delivered under Section 7.1(a)(ii) or
(iii), as applicable. The Applicable Commitment Fee Percentage shall be adjusted
on a daily basis based upon the average outstanding daily balance of the
Revolving Credit Obligations of such date.

                (iii) Notwithstanding anything herein to the contrary, from the
        Closing Date to but not including the fifth (5th) Business Day following
        receipt of the Borrower's financial statements delivered pursuant to
        Section 7.1(A)(ii) for the fiscal year ending on or about September 30,
        2003, the Applicable Floating Rate Margins and the Applicable Eurodollar
        Margins shall be determined based upon a Leverage Ratio greater than or
        equal to 3.0 to 1.0.

                (E) Taxes.

                (i) Any and all payments by the Borrower hereunder (whether in
        respect of principal, interest, fees or otherwise) shall be made free
        and clear of and without deduction for any and all present or future
        taxes, levies, imposts, deductions, charges or withholdings or any
        interest, penalties and liabilities with respect thereto, including,
        without duplication of amounts otherwise reimbursable under Section
        4.1(A), those arising after the date hereof as a result of the adoption
        of or any change in any law, treaty, rule, regulation, guideline or
        determination of a Governmental Authority or any change in the
        interpretation or application thereof by a Governmental Authority, but
        excluding, in the case of each Lender and the Administrative Agent, such
        taxes (including income taxes, franchise taxes and branch profit taxes)
        as are imposed on or measured by such Lender's or the Administrative
        Agent's, as the case may be, net income by the United States of America
        or any Governmental Authority of the jurisdiction under the laws of
        which such Lender or the Administrative Agent, as the case may be, is
        organized (all such non-excluded taxes, levies, imposts, deductions,
        charges, withholdings, and liabilities which the Administrative Agent or
        a Lender determines to be applicable to this Agreement, the other Loan
        Documents, the Revolving Loan Commitments, the Loans or the Letters of
        Credit being hereinafter referred to as "TAXES"). If the Borrower shall
        be required by law to deduct or withhold any Taxes from or in respect of
        any sum payable hereunder or under the other Loan Documents to any
        Lender or the Administrative Agent, (a) the sum payable shall be
        increased as may be necessary so that after making all required
        deductions or withholdings (including deductions applicable to
        additional sums payable under this Section 2.15(E)) such Lender or the
        Administrative Agent (as the case may be) receives an amount equal to
        the sum it would have received had no such deductions or withholdings
        been made, (b) the Borrower shall make such deductions or withholdings,
        and (c) the Borrower shall pay the full amount deducted or withheld to
        the relevant taxation authority or other authority in accordance with
        applicable law. If a withholding tax of the United States of America or
        any other Governmental Authority shall be or become applicable (y) after
        the date of this Agreement, to such payments by the Borrower made to the
        Lending Installation or any other office that a Lender may claim as its
        Lending Installation, or (z) after such Lender's selection and
        designation of any other Lending Installation, to such payments made to
        such other Lending Installation, such Lender shall use reasonable
        efforts to make, fund and maintain the affected Loans through another
        Lending Installation of such Lender in another jurisdiction so as to
        reduce the Borrower's liability hereunder, if the making, funding or
        maintenance of such Loans through such other Lending Installation of
        such Lender does not, in the judgment of such Lender, otherwise
        adversely affect such Loans, or obligations under the Revolving Loan
        Commitments of such Lender.

                (ii) In addition, the Borrower agrees to pay any present or
        future stamp or documentary taxes or any other excise or property taxes,
        charges, or similar levies which arise from any payment made hereunder,
        from the issuance of Letters of Credit hereunder, or from the execution,
        delivery or registration of, or otherwise with respect


                                       45
<PAGE>

        to, this Agreement, the other Loan Documents, the Revolving Loan
        Commitments, the Loans or the Letters of Credit (hereinafter referred to
        as "OTHER Taxes").

                (iii) The Borrower indemnifies each Lender and the
        Administrative Agent for the full amount of Taxes and Other Taxes
        (including, without limitation, any Taxes or Other Taxes imposed by any
        Governmental Authority on amounts payable under this Section 2.15(E))
        paid by such Lender or the Administrative Agent (as the case may be) and
        any liability (including penalties, interest, and expenses) arising
        therefrom or with respect thereto, whether or not such Taxes or Other
        Taxes were correctly or legally asserted. This indemnification shall be
        made within thirty (30) days after the date such Lender or the
        Administrative Agent (as the case may be) makes written demand therefor.
        If the Taxes or Other Taxes with respect to which the Borrower or any
        Subsidiary has made either a direct payment to the taxation or other
        authority or an indemnification payment hereunder are subsequently
        refunded to any Lender, such Lender will return to the Borrower, if no
        Default has occurred and is continuing, an amount equal to the lesser of
        the indemnification payment or the refunded amount. And if a Default
        shall have occurred, such refunded amount shall be applied in the same
        manner as Designated Prepayments set forth in Section 2.5(B)(i)(e)
        hereof. A certificate as to any additional amount payable to any Lender
        or the Administrative Agent under this Section 2.15(E) submitted to the
        Borrower and the Administrative Agent (if a Lender is so submitting) by
        such Lender or the Administrative Agent shall show in reasonable detail
        the amount payable and the calculations used to determine such amount
        and shall, absent manifest error, be final, conclusive and binding upon
        all parties hereto. With respect to such deduction or withholding for or
        on account of any Taxes and to confirm that all such Taxes have been
        paid to the appropriate Governmental Authorities, the Borrower shall
        promptly (and in any event not later than thirty (30) days after
        receipt) furnish to each Lender and the Administrative Agent such
        certificates, receipts and other documents as may be required (in the
        reasonable judgment of such Lender or the Administrative Agent) to
        establish any tax credit to which such Lender or the Administrative
        Agent may be entitled.

                (iv) Within thirty (30) days after the date of any payment of
        Taxes or Other Taxes by the Borrower, the Borrower shall furnish to the
        Administrative Agent the original or a certified copy of a receipt
        evidencing payment thereof.

                (v) Without prejudice to the survival of any other agreement of
        the Borrower hereunder, the agreements and obligations of the Borrower
        contained in this Section 2.15(E) shall survive the payment in full of
        all Obligations, the termination of the Letters of Credit and the
        termination of this Agreement.

                (vi) Each Lender shall promptly furnish to the Borrower and the
        Administrative Agent such additional documents as may be reasonably
        required by the Borrower or the Administrative Agent to establish any
        exemption from or reduction of any Taxes or Other Taxes required to be
        deducted or withheld and which may be obtained without undue expense to
        such Lender (collectively, the "EXEMPTION DOCUMENTS"). Notwithstanding
        any other provision of this Section 2.15(E), the Borrower shall not be
        obligated to gross up any payments to any Lender


                                       46
<PAGE>

        pursuant to Section 2.15(E)(i), or to indemnify any Lender pursuant to
        Section 2.15(E)(iii), in respect of United States federal withholding
        taxes to the extent imposed as a result of (x) the failure of such
        Lender to deliver to the Borrower the Exemption Documents, or (y) the
        Lender designating a successor Lending Installation at which it
        maintains its Loans which has the effect of causing such Lender to
        become obligated for tax payments in excess of those in effect
        immediately prior to such designation; provided, however, that the
        Borrower shall be obligated to gross up any payments to any such Lender
        pursuant to Section 2.15(E)(i), and to indemnify any such Lender
        pursuant to Section 2.15(E)(iii), in respect of United States federal
        withholding taxes if (x) any such failure to deliver any Exemption
        Documents or the failure of such Exemption Documents to establish a
        complete exemption from U.S. federal withholding tax or inaccuracy or
        untruth contained therein resulted from a change in any applicable
        statute, treaty, regulation or other applicable law or any
        interpretation of any of the foregoing occurring after the date hereof,
        which change rendered such Lender no longer legally entitled to deliver
        such Exemption Documents or otherwise ineligible for a complete
        exemption from U.S. federal withholding tax, or rendered the information
        or the certifications made in such Exemption Documents untrue or
        inaccurate in any material respect, (y) the redesignation of the
        Lender's Lending Installation was made at the request of the Borrower or
        (z) the obligation to gross up payments to any such Lender pursuant to
        Section 2.15(E)(i), or to indemnify any such Lender pursuant to Section
        2.15(E)(iii), is with respect to a Purchaser that becomes a Purchaser as
        a result of an assignment made at the request of the Borrower.

                (vii) Upon the request, and at the expense of the Borrower, each
        Lender to which the Borrower is required to pay any additional amount
        pursuant to this Section 2.15(E), shall reasonably afford the Borrower
        the opportunity to contest, and shall reasonably cooperate with the
        Borrower in contesting, the imposition of any Tax giving rise to such
        payment; provided, that (a) such Lender shall not be required to afford
        the Borrower the opportunity to so contest unless the Borrower shall
        have confirmed in writing to such Lender its obligation to pay such
        amounts pursuant to this Agreement; and (b) the Borrower shall reimburse
        such Lender for its reasonable attorneys' and accountants' fees and
        disbursements incurred in so cooperating with the Borrower in contesting
        the imposition of such Tax; provided, however, that notwithstanding the
        foregoing, no Lender shall be required to afford the Borrower the
        opportunity to contest, or cooperate with the Borrower in contesting,
        the imposition of any Taxes, if such Lender reasonably and in good faith
        determines that to do so would have an adverse effect on it.

                2.16 Notification of Advances, Interest Rates, Prepayments and
Aggregate Revolving Loan Commitment Reductions. Promptly after receipt thereof,
the Administrative Agent will notify each Lender of the contents of each
Aggregate Revolving Loan Commitment reduction notice, Borrowing/Election Notice,
and repayment notice received by it hereunder. The Administrative Agent will
notify the Borrower and each Lender of the interest rate applicable to each
Eurodollar Rate Loan promptly upon determination of such interest rate and will
give each Lender prompt notice of each change in the Alternate Base Rate.

                2.17 Lending Installations. Subject to the provisions of Section
2.15(E)(i) hereto, each Lender may book its Loans or Letters of Credit at any
Lending Installation selected by such Lender and may change its Lending
Installation from time to time. All terms of this Agreement shall apply to any
such Lending Installation. Each Lender may, by written or facsimile notice to
the Administrative Agent and the Borrower, designate a Lending Installation
through which Loans will be made by it and for whose account Loan payments
and/or payments of L/C Obligations are to be made.

                2.18 Non-Receipt of Funds by the Administrative Agent. Unless
the Borrower or a Lender, as the case may be, notifies the Administrative Agent
prior to the date on which it is scheduled to make payment to the Administrative
Agent of (A) in the case of a Lender, the proceeds of a Loan or (B) in the case
of the Borrower, a payment of principal, interest or fees to the Administrative
Agent for the account of the Lenders, that it does not intend to make such
payment, the Administrative Agent may assume that such payment has been made.
The Administrative Agent may, but shall not be obligated to, make the amount of
such payment available to the intended recipient in reliance upon such
assumption. If such Lender or the Borrower, as the case may be, has not in fact
made such payment to the Administrative Agent, the recipient of such payment
shall, on demand by the Administrative Agent, repay to the Administrative Agent
the amount so made available together with interest thereon in respect of each
day during the period commencing on the date such amount was so made available
by the Administrative Agent until the date the Administrative Agent recovers
such amount at a rate per annum equal to (i) in the case of payment by a Lender,
the Federal Funds Effective Rate for such day or (ii) in the case of payment by
the Borrower, the interest rate applicable to the relevant Loan.

                2.19 Termination Conditions. All of the rights and remedies
under this Agreement and the other Loan Documents shall survive until (A) all of
the Secured Obligations (other than contingent indemnity obligations) shall have
been fully and indefeasibly paid and satisfied in cash, (B) the Commitments and
all financing arrangements among the Borrower and the Lenders shall have been
terminated (including under Hedging Agreements or other agreements with respect
to Hedging Obligations) and (C) all of the Letters of Credit shall have expired,
been cancelled or terminated, or cash collateralized pursuant to the terms of
this Agreement or supported by a letter of credit acceptable to the
Administrative Agent (collectively, the "TERMINATION CONDITIONS").

                2.20 Replacement of Certain Lenders. In the event a Lender
("AFFECTED LENDER") shall have: (A) failed to fund its Pro Rata Share of any
Advance requested by the Borrower, or to fund a Revolving Loan in order to repay
Swing Line Loans pursuant to Section 2.3(D), which such Lender is obligated to
fund under the terms of this Agreement and which failure has not been cured, (B)
requested compensation from the Borrower under Sections 2.15(E), 4.1 or 4.2 to
recover Taxes, Other Taxes or other additional costs incurred by such Lender
which are not being incurred generally by the other Lenders, (C) delivered a
notice pursuant to Section 4.3 claiming that such Lender is unable to extend
Eurodollar Rate Loans to the Borrower for reasons not generally applicable to
the other Lenders or (D) has invoked Section 10.2; then, in any such case, after
engagement of one or more "Replacement Lenders" (as defined below) by the
Borrower and/or the Administrative Agent, the Borrower or the Administrative
Agent may (but shall not be obligated to) make written demand on such Affected


                                       48
<PAGE>

Lender (with a copy to the Administrative Agent in the case of a demand by the
Borrower and a copy to the Borrower in the case of a demand by the
Administrative Agent) for the Affected Lender to assign, and such Affected
Lender shall use commercially reasonable efforts to assign pursuant to one or
more duly executed Assignment Agreements five (5) Business Days after the date
of such demand, to one or more financial institutions that comply with the
provisions of Section 13.3(A) which the Borrower or the Administrative Agent, as
the case may be, shall have engaged for such purpose ("REPLACEMENT LENDER"), all
of such Affected Lender's rights and obligations under this Agreement and the
other Loan Documents (including, without limitation, its Revolving Loan
Commitment, all Loans owing to it, all of its participation interests in
existing Letters of Credit, L/C Drafts and unreimbursed drawings under Letters
of Credit, and its obligation to participate in additional Letters of Credit and
Swing Line Loans hereunder) in accordance with Section 13.3. The Administrative
Agent is authorized (but not required) to execute one or more of such assignment
agreements as attorney-in-fact for any Affected Lender failing to execute and
deliver the same within five (5) Business Days after the date of such demand.
Further, with respect to such assignment the Affected Lender shall have
concurrently received, in cash, all amounts due and owing to the Affected Lender
hereunder or under any other Loan Document, including, without limitation, the
aggregate outstanding principal amount of the Loans owed to such Lender,
together with accrued interest thereon through the date of such assignment,
amounts payable under Sections 2.15(E), 4.1, and 4.2 with respect to such
Affected Lender and compensation payable under Section 2.15(C) in the event of
any replacement of any Affected Lender under clause (B) or clause (C) of this
Section 2.20; provided that upon such Affected Lender's replacement, such
Affected Lender shall cease to be a party hereto but shall continue to be
entitled to the benefits of Sections 2.15(E), 4.1, 4.2, 4.4, and 10.7 (with
respect to all amounts arising under such Sections while such Lender was a party
hereto), as well as to any fees accrued for its account hereunder and not yet
paid, and shall continue to be obligated under Section 11.8.

                   ARTICLE III: THE LETTER OF CREDIT FACILITY

                3.1 Obligation to Issue Letters of Credit. Subject to the terms
and conditions of this Agreement and in reliance upon the representations,
warranties and covenants of the Borrower herein set forth, each Issuing Bank
hereby agrees to issue for the account of the Borrower through such Issuing
Bank's branches as it and the Borrower may jointly agree, one or more Letters of
Credit denominated in Dollars in accordance with this Article III, from time to
time during the period, commencing on the Closing Date and ending on the sixth
(6th) Business Day prior to the Commitment Termination Date.

                3.2 Transitional Provision. Schedule 3.2 contains a schedule of
certain letters of credit issued for the account of the Borrower and its
Subsidiaries by any of the Lenders prior to the Closing Date. Subject to the
satisfaction of the conditions contained in Sections 5.1 and 5.2, from and after
the Closing Date such letters of credit shall be deemed to be Letters of Credit
issued pursuant to this Article III.

                3.3 Types and Amounts. No Issuing Bank shall have any obligation
to and no Issuing Bank shall:


                                       49
<PAGE>

                (A) issue (or amend) any Letter of Credit if on the date of
        issuance (or amendment), before or after giving effect to the Letter of
        Credit requested hereunder, (i) the amount of the Revolving Credit
        Obligations at such time would exceed the Maximum Revolving Credit
        Amount at such time, or (ii) the aggregate outstanding amount of the L/C
        Obligations would exceed $3,000,000 calculated as of the date of
        issuance of any Letter of Credit; or

                (B) issue (or amend) any Letter of Credit which has an
        expiration date later than the date which is the earlier of (i) one (1)
        year after the date of issuance thereof or (ii) five (5) Business Days
        immediately preceding the Commitment Termination Date; provided, that
        any Letter of Credit with a one year tenor may provide for the renewal
        thereof for additional one year periods (which in no event shall extend
        beyond the date referred to in clause (ii) above).

                3.4 Conditions. In addition to being subject to the satisfaction
of the conditions contained in Sections 5.1 and 5.2, the obligation of an
Issuing Bank to issue any Letter of Credit is subject to the satisfaction in
full of the following conditions:

                (A) the Borrower shall have delivered to the applicable Issuing
        Bank (at such times and in such manner as such Issuing Bank may
        reasonably prescribe) and the Administrative Agent, a request for
        issuance of such Letter of Credit in substantially the form of Exhibit C
        hereto (each such request a "REQUEST FOR LETTER OF CREDIT"), duly
        executed applications for such Letter of Credit, and such other
        documents, instructions and agreements as may be required pursuant to
        the terms thereof (all such applications, documents, instructions, and
        agreements being referred to herein as the "L/C DOCUMENTS"), and the
        proposed Letter of Credit shall be reasonably satisfactory to such
        Issuing Bank as to form and content; and

                (B) as of the date of issuance no order, judgment or decree of
        any court, arbitrator or Governmental Authority shall purport by its
        terms to enjoin or restrain the applicable Issuing Bank from issuing
        such Letter of Credit and no law, rule or regulation applicable to such
        Issuing Bank and no request or directive (whether or not having the
        force of law) from a Governmental Authority with jurisdiction over such
        Issuing Bank shall prohibit or request that such Issuing Bank refrain
        from the issuance of Letters of Credit generally or the issuance of that
        Letter of Credit; and

                (C) in the case of LaSalle acting in its capacity as Issuing
        Bank, the Borrower shall have duly executed and delivered to LaSalle the
        L/C Master Agreement and the Borrower shall be in compliance therewith;
        provided that in the event that the terms and conditions of the L/C
        Master Agreement (or any similar agreement entered into with any other
        Issuing Bank) shall conflict with the terms and conditions of this
        Agreement, the terms and conditions of this Agreement shall govern and
        control to the extent of such conflict.

                3.5 Procedure for Issuance of Letters of Credit.


                                       50
<PAGE>

                (A) Issuance. Subject to the terms and conditions of this
        Article III and provided that the applicable conditions set forth in
        Sections 5.1 and 5.2 hereof have been satisfied, the applicable Issuing
        Bank shall, on the requested date, issue a Letter of Credit on behalf of
        the Borrower in accordance with such Issuing Bank's usual and customary
        business practices and, in this connection, such Issuing Bank may assume
        that the applicable conditions set forth in Section 5.2 hereof have been
        satisfied unless it shall have received notice to the contrary from the
        Administrative Agent or a Lender or has knowledge that the applicable
        conditions have not been met.

                (B) Notice. The applicable Issuing Bank shall give the
        Administrative Agent written notice and or telephonic notice confirmed
        promptly thereafter in writing, of the issuance of a Letter of Credit,
        provided, however, that the failure to provide such notice shall not
        result in any liability on the part of such Issuing Bank.

                (C) No Amendment. No Issuing Bank shall extend or amend any
        Letter of Credit unless the requirements of this Section 3.5 are met as
        though a new Letter of Credit was being requested and issued.

                3.6 Letter of Credit Participation. On the date of this
Agreement, with respect to the Letters of Credit identified on Schedule 3.2, and
immediately upon the issuance of each Letter of Credit hereunder, each Lender
with a Revolving Loan Pro Rata Share shall be deemed to have automatically,
irrevocably and unconditionally purchased and received from the applicable
Issuing Bank an undivided interest and participation in and to such Letter of
Credit, the obligations of the Borrower in respect thereof, and the liability of
such Issuing Bank thereunder (collectively, an "L/C INTEREST") in an amount
equal to the amount available for drawing under such Letter of Credit multiplied
by such Lender's Revolving Loan Pro Rata Share. Each Issuing Bank will notify
each Lender promptly upon presentation to it of an L/C Draft or upon any other
draw under a Letter of Credit. On or before the Business Day on which an Issuing
Bank makes payment of each such L/C Draft or, in the case of any other draw on a
Letter of Credit, on demand by the Administrative Agent or the applicable
Issuing Bank, each Lender shall make payment to the Administrative Agent, for
the account of the applicable Issuing Bank, in immediately available funds in
Dollars in an amount equal to such Lender's Revolving Loan Pro Rata Share of the
amount of such payment or draw. The obligation of each Lender to reimburse the
Issuing Banks under this Section 3.6 shall be unconditional, continuing,
irrevocable and absolute. In the event that any Lender fails to make payment to
the Administrative Agent of any amount due under this Section 3.6, the
Administrative Agent shall be entitled to receive, retain and apply against such
obligation the principal and interest otherwise payable to such Lender hereunder
until the Administrative Agent receives such payment from such Lender or such
obligation is otherwise fully satisfied; provided, however, that nothing
contained in this sentence shall relieve such Lender of its obligation to
reimburse the applicable Issuing Bank for such amount in accordance with this
Section 3.6.

                3.7 Reimbursement Obligation. The Borrower agrees
unconditionally, irrevocably and absolutely to pay immediately to the
Administrative Agent, for the account of the Lenders, the amount of each advance
drawn under or pursuant to a Letter of Credit or an L/C Draft related thereto
(such obligation of the Borrower to reimburse the Administrative Agent for an
advance made under a Letter of Credit or L/C Draft being hereinafter referred to
as a


                                       51
<PAGE>

"Reimbursement Obligation" with respect to such Letter of Credit or L/C Draft),
each such reimbursement to be made by the Borrower no later than the Business
Day on which the applicable Issuing Bank makes payment of each such L/C Draft
or, if the Borrower shall have received notice of a Reimbursement Obligation
later than 12:00 noon (Chicago, Illinois time), on any Business Day or on a day
which is not a Business Day, no later than 12:00 noon (Chicago, Illinois time),
on the immediately following Business Day or, in the case of any other draw on a
Letter of Credit, the date specified in the demand of such Issuing Bank. If the
Borrower at any time fails to repay a Reimbursement Obligation pursuant to this
Section 3.7, the Borrower shall be deemed to have elected to borrow Revolving
Loans from the Lenders, as of the date of the advance giving rise to the
Reimbursement Obligation, equal in amount to the amount of the unpaid
Reimbursement Obligation. Such Revolving Loans shall be made as of the date of
the payment giving rise to such Reimbursement Obligation, automatically, without
notice and without any requirement to satisfy the conditions precedent otherwise
applicable to an Advance of Revolving Loans. Such Revolving Loans shall
constitute a Floating Rate Advance, the proceeds of which Advance shall be used
to repay such Reimbursement Obligation. If, for any reason, the Borrower fails
to repay a Reimbursement Obligation on the day such Reimbursement Obligation
arises and, for any reason, the Lenders are unable to make or have no obligation
to make Revolving Loans, then such Reimbursement Obligation shall bear interest
from and after such day, until paid in full, at the interest rate applicable to
a Floating Rate Advance.

                3.8 Letter of Credit Fees. The Borrower agrees to pay:

                (A) on each Payment Date, in arrears, to the Administrative
        Agent for the ratable benefit of the Lenders, a letter of credit fee at
        a rate per annum equal to the Applicable L/C Fee Percentage on the
        average daily outstanding amount available for drawing under all standby
        Letters of Credit;

                (B) on the date of issuance of each standby Letter of Credit, to
        the applicable Issuing Bank, a letter of credit fronting fee equal to
        0.25% of the stated amount available for drawing under such Letter of
        Credit; and

                (C) to the applicable Issuing Bank, all customary fees and other
        issuance, amendment, cancellation, document examination, negotiation,
        transfer and presentment expenses and related charges in connection with
        the issuance, amendment, cancellation, presentation of L/C Drafts,
        negotiation, transfer and the like customarily charged by such Issuing
        Banks with respect to standby and commercial Letters of Credit,
        including, without limitation, standard commissions with respect to
        commercial Letters of Credit, payable at the time of invoice of such
        amounts.

                3.9 Issuing Bank Reporting Requirements. In addition to the
notices required by Section 3.5(B), each Issuing Bank shall, no later than the
tenth Business Day following the last day of each month, provide to the
Administrative Agent, upon the Administrative Agent's request, schedules, in
form and substance reasonably satisfactory to the Administrative Agent, showing
the date of issue, account party and amount in Dollars, expiration date and the
reference number of each Letter of Credit issued by it outstanding at any time
during such month and the aggregate amount payable by the Borrower during such
month. In addition, upon the request of


                                       52
<PAGE>

the Administrative Agent, each Issuing Bank shall furnish to the Administrative
Agent copies of any Letter of Credit and any application for or reimbursement
agreement with respect to a Letter of Credit to which the Issuing Bank is party
and such other documentation as may reasonably be requested by the
Administrative Agent. Upon the request of any Lender, the Administrative Agent
will provide to such Lender information concerning such Letters of Credit.

                3.10 Indemnification; Exoneration.

                (A) Indemnification. In addition to amounts payable as elsewhere
        provided in this Article III, the Borrower hereby agrees to protect,
        indemnify and pay the Administrative Agent, each Issuing Bank and each
        Lender from and against any and all liabilities and costs which the
        Administrative Agent, such Issuing Bank or such Lender may incur or be
        subject to as a consequence, direct or indirect, of (i) the issuance of
        any Letter of Credit other than, in the case of the applicable Issuing
        Bank, as a result of its Gross Negligence or willful misconduct, as
        determined by the final judgment of a court of competent jurisdiction,
        or (ii) the failure of the applicable Issuing Bank to honor a drawing
        under a Letter of Credit as a result of any act or omission, whether
        rightful or wrongful, of any present or future Governmental Authority
        (all such acts or omissions herein called "GOVERNMENTAL ACTS").

                (B) Risk Assumption. As among the Borrower, the Lenders, the
        Administrative Agent and the Issuing Banks, the Borrower assumes all
        risks of the acts and omissions of, or misuse of such Letter of Credit
        by, the beneficiary of any Letters of Credit. In furtherance and not in
        limitation of the foregoing, subject to the provisions of the Letter of
        Credit applications and Letter of Credit reimbursement agreements
        executed by the Borrower at the time of request for any Letter of
        Credit, neither the Administrative Agent, any Issuing Bank nor any
        Lender shall be responsible (in the absence of Gross Negligence or
        willful misconduct in connection therewith, as determined by the final
        judgment of a court of competent jurisdiction): (i) for the form,
        validity, sufficiency, accuracy, genuineness or legal effect of any
        document submitted by any party in connection with the application for
        and issuance of the Letters of Credit, even if it should in fact prove
        to be in any or all respects invalid, insufficient, inaccurate,
        fraudulent or forged; (ii) for the validity or sufficiency of any
        instrument transferring or assigning or purporting to transfer or assign
        a Letter of Credit or the rights or benefits thereunder or proceeds
        thereof, in whole or in part, which may prove to be invalid or
        ineffective for any reason; (iii) for failure of the beneficiary of a
        Letter of Credit to comply duly with conditions required in order to
        draw upon such Letter of Credit; (iv) for errors, omissions,
        interruptions or delays in transmission or delivery of any messages, by
        mail, cable or other similar form of teletransmission or otherwise; (v)
        for errors in interpretation of technical trade terms; (vi) for the
        misapplication by the beneficiary of a Letter of Credit of the proceeds
        of any drawing under such Letter of Credit; and (vii) for any
        consequences arising from causes beyond the control of the
        Administrative Agent, the Issuing Banks and the Lenders, including,
        without limitation, any Governmental Acts. None of the above shall
        affect, impair, or prevent the vesting of any Issuing Bank's rights or
        powers under this Section 3.10.


                                       53
<PAGE>

                (C) No Liability. In furtherance and extension and not in
        limitation of the specific provisions hereinabove set forth, any action
        taken or omitted by any Issuing Bank under or in connection with the
        Letters of Credit or any related certificates shall not, in the absence
        of negligence in the Issuing Bank's performance or non-performance of
        the express terms of this Agreement or willful misconduct, as determined
        by the final judgment of a court of competent jurisdiction, put the
        applicable Issuing Bank, the Administrative Agent or any Lender under
        any resulting liability to the Borrower or relieve the Borrower of any
        of its obligations hereunder to any such Person.

                (D) Survival of Agreements and Obligations. Without prejudice to
        the survival of any other agreement of the Borrower hereunder, the
        agreements and obligations of the Borrower contained in this Section
        3.10 shall survive the payment in full of principal and interest
        hereunder, the termination of the Letters of Credit and the termination
        of this Agreement.

                3.11 Cash Collateral. Notwithstanding anything to the contrary
herein or in any application for a Letter of Credit, after the occurrence and
during the continuance of a Default, the Borrower shall, on the Business Day
that it receives Administrative Agent's demand, deliver to the Administrative
Agent for the benefit of the Lenders and the Issuing Banks, cash, or other
collateral of a type satisfactory to the Required Lenders, having a value, as
determined by such Lenders, equal to one hundred and five percent (105%) of the
aggregate amount of the outstanding L/C Obligations. Any such collateral shall
be held by the Administrative Agent in a separate account appropriately
designated as a cash collateral account in relation to this Agreement and the
Letters of Credit and retained by the Administrative Agent for the benefit of
the Lenders and the Issuing Banks as collateral security for the Borrower's
obligations in respect of this Agreement and each of the Letters of Credit and
L/C Drafts. Such amounts shall be applied to reimburse the Issuing Banks for
drawings or payments under or pursuant to Letters of Credit or L/C Drafts, or if
no such reimbursement is required, to payment of such of the other Obligations
as the Administrative Agent shall determine. If no Default shall be continuing,
amounts remaining in any cash collateral account established pursuant to this
Section 3.11 which are not to be applied to reimburse an Issuing Bank for
amounts actually paid or to be paid by such Issuing Bank in respect of a Letter
of Credit or L/C Draft, shall be promptly returned to the Borrower, after
deduction of the Administrative Agent's expenses incurred in connection with
such cash collateral account.

                       ARTICLE IV: CHANGE IN CIRCUMSTANCES

                4.1 Yield Protection. If any law or any governmental or
quasi-governmental rule, regulation, policy, guideline or directive (whether or
not having the force of law) adopted after the date of this Agreement and having
general applicability to all banks within the jurisdiction in which such Lender
operates (excluding, for the avoidance of doubt, the effect of and phasing in of
capital requirements or other regulations or guidelines passed prior to the date
of this Agreement), or any interpretation or application thereof by any
Governmental Authority charged with the interpretation or application thereof,
or the compliance of any Lender therewith,

                (A) subjects any Lender or any applicable Lending Installation
        to any tax, duty, charge or withholding on or from payments due from the
        Borrower (other than


                                       54
<PAGE>

        taxation of the overall net income of any Lender or taxation of a
        similar basis, which are governed by Section 2.15(E)), or changes the
        basis of taxation of payments to any Lender in respect of its Revolving
        Loan Commitment, Loans, its L/C Interests, the Letters of Credit or
        other amounts due it hereunder, or

                (B) imposes or increases or deems applicable any reserve,
        assessment, insurance charge, special deposit or similar requirement
        against assets of, deposits with or for the account of, or credit
        extended by, any Lender or any applicable Lending Installation (other
        than reserves and assessments taken into account in determining the
        interest rate applicable to Eurodollar Rate Loans) with respect to its
        Revolving Loan Commitment, Loans, L/C Interests or the Letters of
        Credit, or

                (C) imposes any other condition the result of which is to
        increase the cost to any Lender (other than the cost of funding or
        borrowing) or any applicable Lending Installation of making, funding or
        maintaining its Revolving Loan Commitment, the Loans, the L/C Interests
        or the Letters of Credit or reduces any amount receivable by any Lender
        or any applicable Lending Installation in connection with its Revolving
        Loan Commitment, Loans or Letters of Credit, or requires any Lender or
        any applicable Lending Installation to make any payment calculated by
        reference to the amount of Revolving Loan Commitment, Loans or L/C
        Interests held or interest received by it or by reference to the Letters
        of Credit, by an amount deemed material by such Lender;

                and the result of any of the foregoing is to increase the cost
to that Lender of making, renewing or maintaining its Revolving Loan Commitment,
Loans, L/C Interests, or Letters of Credit or to reduce any amount received
under this Agreement, then, within fifteen (15) days after receipt by the
Borrower of written demand by such Lender pursuant to Section 4.5, the Borrower
shall pay such Lender that portion of such increased expense incurred or
reduction in an amount received which such Lender determines is attributable to
making, funding and maintaining its Loans, L/C Interests, Letters of Credit and
its Revolving Loan Commitment; provided that the Borrower shall be responsible
for any such of the foregoing amounts that has accrued or been assessed to any
Lender not more than 180 days prior to such written demand (or, if longer, such
period during which because of the retroactive application of such law, rule,
regulation, policy, guideline or directive such Lender did not know in good
faith that such amount would arise or accrue).

                4.2 Changes in Capital Adequacy Regulations. If a Lender
reasonably determines (A) the amount of capital required or expected to be
maintained by such Lender, any Lending Installation of such Lender or any
corporation controlling such Lender is increased as a result of a "Change" (as
defined below), and (B) such increase in capital will result in an increase in
the cost to such Lender of maintaining its Revolving Loan Commitment, Loans, L/C
Interests, the Letters of Credit or its obligation to make Loans hereunder,
then, within fifteen (15) days after receipt by the Borrower of written demand
by such Lender pursuant to Section 4.5, the Borrower shall pay such Lender the
amount necessary to compensate for any shortfall in the rate of return on the
portion of such increased capital which such Lender determines is attributable
to this Agreement, its Revolving Loan Commitment, its Loans, its L/C Interests,
the Letters of Credit or its obligation to make Loans hereunder (after taking
into account such Lender's policies as to capital adequacy). "Change" means (i)
any change after the date of this Agreement


                                       55
<PAGE>

in the "Risk-Based Capital Guidelines" (as defined below) excluding, for the
avoidance of doubt, the effect of any phasing in of such Risk-Based Capital
Guidelines or any other capital requirements passed prior to the date hereof, or
(ii) any adoption of or change in any other law, governmental or
quasi-governmental rule, regulation, policy, guideline, interpretation, or
directive (whether or not having the force of law) after the date of this
Agreement which affects the amount of capital required or expected to be
maintained by any Lender or any Lending Installation or any corporation
controlling any Lender. "Risk-Based Capital Guidelines" means (i) the risk-based
capital guidelines in effect in the United States on the date of this Agreement,
including transition rules, and (ii) the corresponding capital regulations
promulgated by regulatory authorities outside the United States implementing the
July 1988 report of the Basle Committee on Banking Regulation and Supervisory
Practices Entitled "International Convergence of Capital Measurements and
Capital Standards," including transition rules, and any amendments to such
regulations adopted prior to the date of this Agreement.

                4.3 Availability of Types of Advances. If (A) any Lender
reasonably determines that maintenance of its Eurodollar Rate Loans at a
suitable Lending Installation would violate any applicable law, rule, regulation
or directive of any Governmental Authority, whether or not having the force of
law, or (B) the Required Lenders reasonably determine that, other than during
the Syndication Period, deposits of a type or maturity appropriate to match fund
Eurodollar Rate Loans are not available, then the Administrative Agent shall
suspend the availability of the affected Type of Advance and, in the case of any
occurrence set forth in clause (A), require any Advances of the affected Type to
be repaid or converted into another Type, provided that such repayment or
conversion shall entitle the Lenders to funding indemnification contained in
Section 4.4 with respect to any Eurodollar Rate Advance only upon the occurrence
of a change in a law, rule or regulation occurring after the Borrowing Date of
such Eurodollar Rate Advance.

                4.4 Funding Indemnification. If any payment of a Eurodollar Rate
Loan occurs on a date which is not the last day of the applicable Interest
Period, whether because of acceleration, prepayment, or otherwise, or a
Eurodollar Rate Loan is not made on the date specified by the Borrower for any
reason other than default by the Lenders, or a Eurodollar Rate Loan is not
prepaid on the date specified by the Borrower for any reason, the Borrower
indemnifies each Lender for any loss or cost incurred by it resulting therefrom,
including, without limitation, any loss or cost in liquidating or employing
deposits acquired to fund or maintain the Eurodollar Rate Loan. In connection
with any assignment by any Lender of any portion of the Loans made pursuant to
Section 13.3 and made during the Syndication Period, and if, notwithstanding the
provisions of Section 2.4, the Borrower has requested and the Administrative
Agent has consented to the use of the Eurodollar Rate, the Borrower shall be
deemed to have repaid all outstanding Eurodollar Rate Advances as of the
effective date of such assignment and reborrowed such amount as a Floating Rate
Advance and/or Eurodollar Rate Advance (chosen in accordance with the provisions
of Section 2.4) and the indemnification provisions under this Section 4.4 shall
apply.

                4.5 Lender Statements; Survival of Indemnity. If reasonably
possible, each Lender shall designate an alternate Lending Installation with
respect to its Eurodollar Rate Loan to reduce any liability of the Borrower to
such Lender under Sections 4.1 and 4.2 or to avoid the unavailability of a Type
of Advance under Section 4.3, so long as such designation is not, in the


                                       56
<PAGE>

reasonable judgment of the Lender, disadvantageous to such Lender. Each Lender
shall deliver a written statement of such Lender to the Borrower (with a copy to
the Administrative Agent) as to the amount due, if any, under Section 2.15(E),
4.1, 4.2 or 4.4 and shall set forth in reasonable detail the calculations upon
which such Lender determined such amount and shall be final, conclusive and
binding on the Borrower in the absence of demonstrable error. Determination of
amounts payable under such Sections in connection with a Eurodollar Rate Loan
shall be calculated as though each Lender funded its Eurodollar Rate Loan
through the purchase of a deposit of the type and maturity corresponding to the
deposit used as a reference in determining the Eurodollar Rate applicable to
such Loan, whether in fact that is the case or not. Unless otherwise provided
herein, the amount specified in the written statement of any Lender shall be
payable on demand after receipt by the Borrower of such statement. The
obligations of the Borrower under Sections 2.15(E), 4.1, 4.2 and 4.4 shall
survive payment of the Obligations and termination of this Agreement.

        Obligations do not, and after making such proposed Advance or issuing
        such Letter of Credit would not, exceed the Maximum Revolving Credit
        Amount.

                Each Borrowing/Election Notice with respect to each such Advance
and the letter of credit application with respect to each Letter of Credit shall

        otherwise with any Governmental Authority.

                (B) Execution and Delivery. The execution, delivery, performance
        and filing, as the case may be, of each of the Transaction Documents
        which must be executed or filed by the Borrower or any of its
        Subsidiaries in connection with the IITRI Acquisition or the ESOT
        Transaction or which have been executed or filed as required by this
        Agreement, the other Loan Documents or otherwise and to which the
        Borrower or any of its Subsidiaries is party, and the consummation of
        the transactions contemplated thereby, have been duly approved by the
        respective boards of directors and, if necessary, the stockholders or
        unitholders of the Borrower and its Subsidiaries, and such approvals
        have not been rescinded. No other action or proceedings on the part of
        the Borrower or its Subsidiaries are necessary to consummate such
        transactions.

                (C) Transaction Documents. Each of the Transaction Documents to
        which the Borrower or any of its Subsidiaries is a party has been duly
        executed, delivered or filed, as the case may be, by it and constitutes
        its legal, valid and binding obligation, enforceable against it in
        accordance with its terms (except as enforceability may be limited by
        bankruptcy, insolvency, or similar laws affecting the enforcement of
        creditors' rights generally), is in full force and effect, and no
        material term or condition thereof has been amended, modified or waived
        from the terms and conditions contained in the Transaction Documents
        delivered to the Administrative Agent pursuant to Section 5.1 without
        the prior written consent of the Administrative Agent, and the Borrower
        and its Subsidiaries have, and, to the best of the Borrower's and its
        Subsidiaries' knowledge, all other parties thereto have, performed and
        complied with all the terms, provisions, agreements and conditions set
        forth therein and required to be performed or complied with in all
        material respects by such parties, and no unmatured default, default or
        breach of any covenant by any such party exists thereunder.

                6.3 No Conflict; Governmental Consents. The execution, delivery
and performance of each of the Loan Documents and other Transaction Documents to
which the Borrower or any of its Subsidiaries is a party do not and will not (A)
conflict with the Constituent Documents of the Borrower or any such Subsidiary,
(B) (i) constitute a tortious interference with any Contractual Obligation of
any Person or (ii) conflict with, result in a breach of or constitute (with or
without notice or lapse of time or both) a default under any Requirement of Law
(including, without limitation, any Environmental Property Transfer Act) or
Contractual Obligation of the Borrower or any such Subsidiary, or require
termination of any Contractual Obligation of the Borrower or any such Subsidiary
which, in the case of this clause (ii), could be reasonably anticipated to
result in a Material Adverse Effect, (C) result in or require the creation or
imposition of any Lien whatsoever upon any of the property or assets of the
Borrower or any such Subsidiary, other than Liens permitted or created by the
Transaction Documents, or (D) require any approval of the Borrower's or any such
Subsidiary's Board of Directors or shareholders or unitholders except such as
have been obtained. Except as set forth on Schedule


                                       63
<PAGE>

6.3 to this Agreement, the execution, delivery and performance of each of the
Transaction Documents to which the Borrower or any of its Subsidiaries is a
party do not and will not require any registration with, consent or approval of,
or notice to, or other action to, with or by any Governmental Authority,
including under any Environmental Property Transfer Act, except filings,
consents or notices which have been made, obtained or given, or which, if not
made, obtained or given, individually or in the aggregate could not reasonably
be expected to have a Material Adverse Effect.

              6.4 Financial Statements.


              (A) Pro Forma Financials. The combined, projected pro forma
       balance sheet, income statements and statements of cash flow of the
       Borrower and its Subsidiaries, copies of which are attached hereto as
       Schedule 6.4 to this Agreement, present on a pro forma basis the
       financial condition of the Borrower and such Subsidiaries as of such
       date, and reflect on a pro forma basis those liabilities reflected in the
       notes thereto and resulting from consummation of the IITRI Acquisition,
       the ESOT Transaction, the issuance of the Subordinated Notes and the
       other transactions contemplated by this Agreement, and the payment or
       accrual of all transaction costs payable on the Closing Date with respect
       to any of the foregoing. The projections and assumptions expressed in the
       pro forma financials referenced in this Section 6.4(A) were prepared in
       good faith and represent management's opinion based on the information
       available to the Borrower at the time so furnished and, since the
       preparation thereof and up to the Closing Date, there has occurred no
       change in the business, financial condition, operations, or prospects of
       the Borrower or any of its Subsidiaries, or the Borrower and its
       Subsidiaries taken as a whole which has had or could reasonably be
       expected to have a Material Adverse Effect.

              (B) Audited Financial Statements. Complete and accurate copies of
       the audited financial statements and the audit reports related thereto of
       IITRI and its consolidated Subsidiaries as at September 30, 2001 and of
       the business and assets of IITRI to be acquired by the Borrower pursuant
       to the Asset Purchase Agreement as at September 30, 2001, and (ii) the
       unaudited financial statements of IITRI and its consolidated Subsidiaries
       as of September 30, 2002 and of the business and assets of IITRI to be
       acquired by the Borrower pursuant to the Asset Purchase Agreement as of
       September 30, 2002, have been delivered to the Administrative Agent.

              6.5    No Material Adverse Change.

              (A) Prior to Closing Date. Since September 30, 2001 up to the
       Closing Date, there has occurred no change in the business, properties,
       condition (financial or otherwise), performance, results of operations or
       prospects of IITRI and its consolidated Subsidiaries, the Borrower, any
       Guarantor, or the Borrower and its Subsidiaries, in each case, taken as a
       whole or any other event which has had or could reasonably be expected to
       have a Material Adverse Effect.

              (B) From and After Closing Date. Since the Closing Date, there has
       occurred no change in the business, properties, condition (financial or
       otherwise), performance, results of operations or prospects of the
       Borrower, any Guarantor or the Borrower and its




                                       64
<PAGE>


       Subsidiaries, in each case, taken as a whole or any other event which has
       had or could reasonably be expected to have a Material Adverse Effect.

              6.6 Taxes.

              (A) Tax Examinations. All deficiencies which have been asserted
       against the Borrower or any of the Borrower's Subsidiaries as a result of
       any federal, state, local or foreign tax examination for each taxable
       year in respect of which an examination has been conducted have been
       fully paid or finally settled or are being contested in good faith, and
       no issue has been raised by any taxing authority in any such examination
       which, by application of similar principles, could reasonably be expected
       to result in assertion by such taxing authority of a material deficiency
       for any other year not so examined which has not been reserved for in the
       Borrower's consolidated financial statements to the extent, if any,
       required by Agreement Accounting Principles. Except as permitted pursuant
       to Section 7.2(D), neither the Borrower nor any of the Borrower's
       Subsidiaries anticipates any tax liability with respect to the years
       which have not been closed pursuant to applicable law.

              (B) Payment of Taxes. All tax returns and reports of the Borrower
       and its Subsidiaries required to be filed have been timely filed, and all
       taxes, assessments, fees and other governmental charges thereupon and
       upon their respective property, assets, income and franchises which are
       shown in such returns or reports to be due and payable have been paid
       except those items which are being contested in good faith and have been
       reserved for in accordance with Agreement Accounting Principles. The
       Borrower has no knowledge of any proposed tax assessment against the
       Borrower or any of its Subsidiaries that will have or could reasonably be
       expected to have a Material Adverse Effect.

              (C) Subchapter S Status; ESOT Tax-Exempt Status. As of the Closing
       Date, the Borrower will have executed the applicable election forms or
       other filings required to be made for purposes of the Borrower's election
       to be taxed as an "S corporation" as such term is defined in Section 1361
       of the Code. Beginning with the Borrower's taxable year ending September
       30, 2002, the Borrower is taxable as an S corporation. The ESOT is not
       subject to tax imposed under the Code with respect to any item of income
       or loss of the Borrower or any Subsidiary of the Borrower.

              6.7 Litigation; Loss Contingencies and Violations.

              (A) Litigation. Except as set forth in Schedule 6.7 (the
       "DISCLOSED LITIGATION"), there is no action, suit, proceeding,
       arbitration or, to the Borrower's knowledge, investigation before or by
       any Governmental Authority or private arbitrator pending or, to the
       Borrower's knowledge, threatened against or affecting the Borrower or any
       of its Subsidiaries or any property of any of them. Neither any of the
       Disclosed Litigation nor any action, suit, proceeding, arbitration or
       investigation which has commenced since the Closing Date (or the most
       recent update of the Disclosed Litigation) (i) challenges the validity or
       the enforceability of any material provision of the Transaction Documents
       or (ii) has or could reasonably be expected to have a Material



                                       65
<PAGE>


       Adverse Effect. Neither the Borrower nor any of its Subsidiaries is (x)
       in violation of any applicable Requirements of Law which violation will
       have or could reasonably be expected to have a Material Adverse Effect,
       or (y) subject to or in default with respect to any final judgment, writ,
       injunction, restraining order or order of any nature, decree, rule or
       regulation of any court or Governmental Authority which will have or
       could reasonably be expected to have a Material Adverse Effect. To the
       Borrower's knowledge, neither the ESOP Fiduciary nor the ESOT Trustee has
       made any assertion with respect to the ESOP or ESOT contrary to or
       inconsistent with the accuracy of any representation or warranty set
       forth at Section 6.6(C) or Section 6.20 that could reasonably be expected
       to result in a Material Adverse Effect.

              (B) Loss Contingencies. There is no material loss contingency
       within the meaning of Agreement Accounting Principles which has not been
       reflected in the consolidated financial statements of the Borrower
       prepared and delivered pursuant to Section 7.1(A) for the fiscal period
       during which such material loss contingency was incurred.

              6.8    Subsidiaries.

              (A) Subsidiaries and Redemption Rights. Schedule 6.8(A) to this
       Agreement (i) contains a description of the corporate structure of the
       Borrower and its Subsidiaries; and (ii) accurately sets forth (a) the
       correct legal name, the jurisdiction of incorporation and the
       jurisdictions in which each of the Borrower and the direct and indirect
       Subsidiaries of the Borrower are qualified to transact business as a
       foreign corporation, (b) the authorized, issued and outstanding shares of
       each class of Capital Stock of the Borrower and each of its Subsidiaries
       and the owners of such shares, and (c) a summary of the direct and
       indirect partnership, joint venture, or other Equity Interests, if any,
       of the Borrower and each of its Subsidiaries in any Person. None of the
       Borrower's Subsidiaries is a Foreign Subsidiary. Except for (a) mandatory
       redemption or repurchase of Capital Stock of the Borrower as a result of
       distributions by the ESOT to participants of the ESOP pursuant to the
       ESOP Plan Documents subsequent to their termination of employment with
       the Borrower or any Controlled Group member, (b) the requirements of
       Section 401(a)(28) of the Code or any substantially similar Requirement
       of Law or as otherwise permitted by Section 7.3(F) hereto, (c) the
       vesting provisions of the ESOP, (d) the Incentive Arrangements, (e) the
       put and call rights contained in the Seller Warrants and (f) agreements
       otherwise disclosed on Schedule 6.8(A), none of the issued and
       outstanding Capital Stock of the Borrower or any of the Borrower's
       Subsidiaries is subject to any vesting, redemption, or repurchase
       agreement, and there are no warrants or options outstanding with respect
       to such Capital Stock, except for the Seller Warrants and except as may
       be in effect from time to time with respect to Incentive Arrangements.
       The outstanding Capital Stock of the Borrower and each of its
       Subsidiaries is duly authorized, validly issued, fully paid and
       nonassessable and is not Margin Stock.

              (B)    As of the Closing Date:

              (i) except as provided in the Rights Agreement and the Seller
       Warrants, the Borrower's Capital Stock is not subject to any preemptive
       right, right of first refusal



                                       66
<PAGE>

       or offer or similar right on the part of any other Person, and all of
       such Capital Stock has been (or will have been) offered and issued in
       accordance with all applicable laws; and, except as set forth on Schedule
       6.8(B)(i) and except to the extent Persons may be deemed beneficial
       owners by virtue of familial relationships with a holder of Capital Stock
       or in connection with a trust established for the benefit of family
       members by a holder of Capital Stock, the owners of the Capital Stock
       indicated on Schedule 6.8(B)(i) own the Capital Stock indicated on such
       exhibit free of any Lien, proxy, voting agreement, voting trust,
       stockholders agreement (other than the Rights Agreement) or similar
       agreement or restriction; and, except as set forth on Schedule 6.8(B)(i),
       neither the Constituent Documents nor any other agreement, document or
       instrument binding on or applicable to the Borrower or any of its
       Subsidiaries or any of its stockholders contains any provision requiring
       a higher voting requirement with respect to action taken (and/or to be
       taken) by its board of directors or stockholders than that which would
       apply in the absence of such provision;

              (ii) except as provided in the Rights Agreement and the Seller
       Warrants and except as set forth on Schedule 6.8(B)(ii) attached hereto
       (after giving effect to the consummation of the transactions consummated
       on the Closing Date under the Transaction Documents), (a) there are no
       outstanding securities convertible into or exercisable or exchangeable
       for any Capital Stock of the Borrower or any of its Subsidiaries and no
       outstanding agreements for the purchase from, or sale or issuance by, the
       Borrower or any of its Subsidiaries of any of their respective Capital
       Stock or any securities convertible into or exercisable or exchangeable
       for such Capital Stock; (b) there are no agreements on the part of the
       Borrower or any of its Subsidiaries to issue, sell or distribute any of
       their respective Capital Stock, other securities or assets; (c) neither
       the Borrower nor any of its Subsidiaries has any obligation (contingent
       or otherwise) to purchase, redeem or otherwise acquire any of their
       respective Capital Stock or other securities or any interest therein or
       to pay any dividend or make any distribution in respect thereof; and (d)
       no Person is entitled to any rights with respect to the registration of
       any Capital Stock or other securities of the Borrower or any of its
       Subsidiaries under the Securities Act (or the securities laws of any
       other jurisdiction); and

              (iii) the aggregate number of shares of common stock of the
       Borrower issuable upon exercise in full of the Seller Warrants issued
       pursuant to the terms of the Senior Subordinated Securities Purchase
       Agreement immediately after the Closing is approximately 523,871, which,
       if then issued, would constitute approximately twelve and fifty-four
       one-hundredths of one percent (12.54%) of the common stock of the
       Borrower (calculated assuming the conversion, exercise and exchange of
       all outstanding securities convertible into and exercisable or
       exchangeable for shares of common stock of the Borrower, including,
       without limitation, the Seller Warrants). The Borrower has reserved
       approximately 523,871 shares of common stock of the Borrower solely for
       issuance upon exercise of the Seller Warrants issued pursuant to the
       terms of the Senior Subordinated Securities Purchase Agreement. The
       Borrower has adopted a stock appreciation rights plan. The Borrower has
       not reserved any shares of common stock of the Borrower pursuant to the
       Borrower's stock appreciation rights plan.

              6.9    ERISA.


              (A) List of Plans. Set forth in Schedule 6.9(A) is a true and
       complete list of each material Plan that, as of the date of this
       Agreement, is or was an "employee pension benefit plan" (as such term is
       defined in Section 3(2) of ERISA). Set forth in Schedule 6.9(A) is a true
       and complete list of each material Plan that, as of the date of this
       Agreement, is or was an "employee welfare benefit plan" (as such term is
       defined in Section 3(1) of ERISA).

              (B) List of Non-ERISA Commitments. Set forth in Schedule 6.9(B) is
       a true and complete list of each material Non-ERISA Commitment adopted by
       the Borrower or any of its Subsidiaries and in effect as of the date of
       this Agreement. Upon the Request of the Administrative Agent, the
       Borrower will deliver to the Administrative Agent true and complete
       copies in existence as of the date of this Agreement of (i) all written
       Non-ERISA Commitments disclosed on Schedule 6.9(B) and (ii) all insurance
       and annuity policies and contracts and other funding arrangements and
       other documents relevant to any Non-ERISA Commitment disclosed on
       Schedule 6.9(B).

              (C) Plan Documents. The ESOP Plan Documents identified in Schedule
       1.1.5 (each as may be amended from time to time as provided herein) are
       all of the material documents pursuant to which the ESOP and ESOT are
       maintained by the Borrower, or concerning the Borrower's obligations with
       respect to the ESOP and ESOT. The ESOT Transaction Documents identified
       in Schedule 1.1.6 (without any modifications or amendments thereto),
       together with the ESOP Plan Documents identified in Schedule 1.1.5
       (without any modifications or amendments thereto), are all duly adopted
       by the Borrower to the extent intended to be so adopted.

              (D) Plan Events. The representations and warranties in this
       Section 6.9(D) are subject to the disclosures made on Schedule 6.9 (D).
       No Benefit Plan has incurred any material accumulated funding deficiency
       (as defined in Sections 302(a)(2) of ERISA and 412(a) of the Code)
       whether or not waived. Neither the Borrower nor any member of the
       Controlled Group has incurred any material liability to the PBGC which
       remains outstanding other than the payment of premiums, and there are no
       premium payments which have become due which are unpaid. With respect to
       each Benefit Plan, Schedule B to the most recent annual report filed with
       the IRS with respect to such plan is complete and accurate in all
       material respects. Since the date of each such Schedule B, there has been
       no material adverse change in the funding status or financial condition
       of the Benefit Plan relating to such Schedule B. As of the last day of
       the most recent prior plan year, the market value of assets under each
       Benefit Plan, other than any Multiemployer Plan, was not by a material
       amount less than the present value of benefit liabilities thereunder
       (determined in accordance with the actuarial valuation assumptions
       described therein). Neither the Borrower nor any member of the Controlled
       Group has (i) failed to make a required contribution or payment to a
       Multiemployer Plan of a material amount or (ii) incurred a material
       complete or partial withdrawal under Sections 4203 or 4205 of ERISA from
       a Multiemployer Plan. Neither the Borrower nor any member of the
       Controlled Group has failed to make a required installment or any other
       required payment under Section 412 of the Code on or before the due date
       for such installment or



                                       68
<PAGE>


       other payment. Neither the Borrower nor any member of the Controlled
       Group is required to provide security of a material amount to a Benefit
       Plan pursuant to Section 401(a)(29) of the Code due to a Plan amendment
       that results in an increase in current liability for the plan year.
       Except as set forth on Schedule 6.9, neither the Borrower nor any of its
       Subsidiaries maintains or contributes to any employee welfare benefit
       plan within the meaning of Section 3(1) of ERISA or any other arrangement
       which provides benefits to one or more employees, officers, directors, or
       consultants after termination of employment other than as required by
       Section 601 of ERISA or Section 4980(B) of the Code or applicable law and
       other than any such plan or arrangement with respect to which the
       Borrower and its Subsidiaries do not have any liability of a material
       amount. Each Plan which is intended to be qualified under Section 401(a)
       of the Code as currently in effect is designed to be qualified, and each
       trust related to any such Plan is designed to be exempt from federal
       income tax under Section 501(a) of the Code as currently in effect. With
       respect to each Plan, the Borrower and each of its Subsidiaries and the
       ESOP Fiduciary and, to the best knowledge of the Borrower, the ESOT
       Trustee are in compliance in all material respects with the
       responsibilities, obligations and duties, if any, imposed on them by
       ERISA and the Code. Each Plan and Non-ERISA Commitment complies in all
       material respects in form, and has been administered in all material
       respects in accordance with its terms and, in accordance with all
       applicable laws and regulations, including but not limited to ERISA and
       the Code. On the Closing Date and, to the best knowledge of the Borrower,
       at all times thereafter, there is no material action, suit or claim
       pending or threatened with respect to any Plan other than routine claims
       for benefits. On the Closing Date and, to the best knowledge of the
       Borrower, at all times thereafter, there have been no and there is no
       non-exempt prohibited transaction described in Sections 406 of ERISA or
       4975 of the Code which could reasonably be expected to subject the
       Borrower to material liability. Neither the Borrower nor any member of
       the Controlled Group has taken or failed to take any action which would
       constitute or result in a Termination Event, which action or inaction
       could reasonably be expected to subject the Borrower or any of its
       Subsidiaries to liability, individually or in the aggregate, in excess of
       $1,000,000. Neither the Borrower nor any Subsidiary is subject to any
       material liability under, or to the best of Borrower's knowledge, has any
       potential material liability under, Sections 4063, 4064, 4069, 4204 or
       4212(c) of ERISA and no other member of the Controlled Group is subject
       to any liability under Sections 4063, 4064, 4069, 4204 or 4212(c) of
       ERISA. Except as set forth on Schedule 6.9(D), neither the Borrower nor
       any of its Subsidiaries has, by reason of the ESOT Transaction or the
       making of any Advances hereunder, any obligation to make any payment to
       any current or former employee, director, officer or consultant pursuant
       to any Plan or Non-ERISA Commitment or any obligation to make any such
       payment at a time earlier than when it would be otherwise payable except
       for any payment to be made upon termination of employment. For purposes
       of this Section 6.9(D), "material" means any amount, noncompliance or
       basis for liability which could reasonably be expected to subject the
       Borrower or any of its Subsidiaries to liability, individually or in the
       aggregate, in excess of $1,000,000.

              6.10 Accuracy of Information. The information, exhibits and
reports (i) prepared by the Borrower and (ii) prepared by any other Person, in
each case, furnished by or on behalf of the Borrower and any of its Subsidiaries
to the Administrative Agent or to any Lender



                                       69
<PAGE>

in connection with the negotiation of, or compliance with, the Loan Documents,
the representations and warranties of the Borrower and its Subsidiaries
contained in the Loan Documents, and all certificates and documents delivered to
the Administrative Agent and the Lenders pursuant to the terms thereof, taken as
a whole, do not contain, and with respect to the information, exhibits and
reports identified in clause (ii) above, to the best of the Borrower's knowledge
do not contain, as of the date furnished any untrue statement of a material fact
or omit to state a material fact necessary in order to make the statements
contained herein or therein, in light of the circumstances under which they were
made, not misleading.

              6.11 Securities Activities. Neither the Borrower nor any of its
Subsidiaries is engaged in the business of extending credit for the purpose of
purchasing or carrying Margin Stock. Margin Stock constitutes less than 25% of
the value of those assets of the Borrower and its Subsidiaries which are subject
to any limitation on sale, pledge, or other restriction hereunder.

              6.12 Material Agreements. Neither the Borrower nor any of its
Subsidiaries is a party to any Contractual Obligation or subject to any charter
or other corporate restriction which individually or in the aggregate has had or
could reasonably be expected to have a Material Adverse Effect. Except as set
forth on Schedule 6.12, neither the Borrower nor any of its Subsidiaries has
received notice or has knowledge that (A) it is in default in the performance,
observance or fulfillment of any of the obligations, covenants or conditions
contained in any Contractual Obligation applicable to it, or (B) any condition
exists which, with the giving of notice or the lapse of time or both, would
constitute a default with respect to any such Contractual Obligation, in each
case, except where such default or defaults, if any, individually or in the
aggregate will not have or could not reasonably be expected to have a Material
Adverse Effect.

              6.13 Compliance with Laws. The Borrower and its Subsidiaries are
in compliance with all Requirements of Law applicable to them and their
respective businesses, in each case where the failure to so comply individually
or in the aggregate could reasonably be expected to have a Material Adverse
Effect.

              6.14 Assets and Properties. The Borrower and each of its
Subsidiaries has good and marketable title to all of its assets and properties
(tangible and intangible, real or personal) owned by it and a valid leasehold
interest in all of its leased assets (except insofar as marketability may be
limited by any laws or regulations of any Governmental Authority affecting such
assets), and all such assets and property are free and clear of all Liens,
except Liens permitted under Section 7.3(C). Substantially all of the assets and
properties owned by, leased to or used by the Borrower and/or each such
Subsidiary of the Borrower are in adequate operating condition and repair,
ordinary wear and tear excepted. Neither this Agreement nor any other
Transaction Document, nor any transaction contemplated under any such agreement,
will affect any right, title or interest of the Borrower or such Subsidiary in
and to any of such assets in a manner that would have or could reasonably be
expected to have a Material Adverse Effect.

              6.15 Statutory Indebtedness Restrictions. Neither the Borrower nor
any of its Subsidiaries is subject to regulation under the Public Utility
Holding Company Act of 1935, the Federal Power Act, the Interstate Commerce Act,
or the Investment Company Act of 1940, or




                                       70
<PAGE>

any other foreign, federal or state statute or regulation which limits its
ability to incur indebtedness or its ability to consummate the transactions
contemplated hereby.

              6.16 Insurance. Schedule 6.16 to this Agreement accurately sets
forth as of the Closing Date all insurance policies and programs currently in
effect with respect to the respective properties and assets and business of the
Borrower and its Subsidiaries, specifying, for each such policy and program, (A)
the amount thereof, (B) the risks insured against thereby, (C) the name of the
insurer and each insured party thereunder, (D) the policy or other
identification number thereof, (E) the expiration date thereof, and (F) any
reserves relating to any self-insurance program that is in effect. Such
insurance policies and programs reflect coverage that is reasonably consistent
with prudent industry practice, and shall include, without limitation, property
and liability (and, if appropriate, business interruption) insurance.

              6.17 Labor Matters. As of the Closing Date, no attempt to organize
the employees of the Borrower or any of its Subsidiaries, and no labor disputes,
strikes or walkouts affecting the operations of the Borrower or any of its
Subsidiaries, is pending, or, to the Borrower's knowledge, threatened, planned
or contemplated.

       Borrower's knowledge, the other parties thereto, has occurred (except for
       such breaches, defaults and waivers, if any, consented to in writing by
       the Administrative Agent) and no action has been taken by any competent
       authority which restrains, prevents or imposes any material adverse
       condition upon, or seeks to restrain, prevent or impose any material
       adverse condition upon, the IITRI Acquisition or the ESOT Transaction;

              (B) The representations and warranties of the Borrower contained

       conditions precedent to, and all consents necessary to permit, the
       funding of the IITRI Acquisition and the ESOT Transaction have been
       satisfied or waived with the approval of the Administrative Agent (such
       approval not to be unreasonably withheld).

              6.19 Environmental Matters.

              (A) Environmental Representations. Except as disclosed on Schedule
       6.19 to this Agreement:

       to the Borrower or any of its Subsidiaries, any judicial, administrative
       or regulatory proceeding (including enforcement proceeding), order,
       judgment, decree, settlement or other agreement respecting: (a) any
       alleged or actual material violation of Environmental, Health or Safety
       Requirements of Law; (b) any material remedial action; or (c) any
       material claims or liabilities arising from the Release or threatened
       Release of a Contaminant into the environment;

              (iv) there is not now, nor to the Borrower's or any of its
       Subsidiaries' knowledge has there ever been, on or in the property of the
       Borrower or any of its Subsidiaries any landfill, waste pile, underground
       storage tanks, aboveground storage tanks, surface impoundment or
       hazardous waste or hazardous material storage facility of any kind, any
       polychlorinated biphenyls (PCBs) used in hydraulic oils, electric

       to perform its obligations under and the transactions contemplated by the
       Transaction Documents and the ESOP Plan Documents. As of the Closing Date
       and,


                                       72
<PAGE>

       to the best of Borrower's knowledge at all times thereafter, the
       execution and delivery by the ESOT of the Transaction Documents and the
       ESOP Plan Documents have been duly authorized and completed by all
       necessary actions of it and such executions and deliveries and the
       performance by it of its obligations under and the transactions
       contemplated by the Transaction Documents and the ESOP Plan Documents do
       not contravene any provision of law and the Transaction Documents and the
       ESOP Plan Documents which have been or are to be executed by it are

       may be limited by bankruptcy, insolvency, reorganization, or moratorium
       or other similar laws relating to the enforcement of creditors' rights
       generally and by general equitable principles other than general
       equitable principles as may be applicable to any non-exempt prohibited
       transactions described in Section 406 of ERISA or Section 4975 of the
       Code. Each of such Transaction Documents and the ESOP Plan Documents is
       in full force and effect and no term or condition thereof has been
       amended, modified or waived from the terms and conditions contained in
       the Transaction Documents and the ESOP Plan Documents delivered to the
       Administrative Agent pursuant to Section 5.1 without the consent of the
       Administrative Agent (which consent shall not be unreasonably withheld),
       except to the extent such amendment, modification or waiver could not
       reasonably be anticipated to have a material adverse effect upon the
       Administrative Agent or any of the Lenders or otherwise have a Material
       Adverse Effect. As of the Closing Date and, to the best of Borrower's
       knowledge at all times thereafter, the ESOT has performed and complied

       Documents to which the ESOT is a party do not (i) conflict with the ESOP
       Plan Documents, (ii) conflict with any Requirement of Law, or (iii)

       of the Code has occurred with respect to the ESOP, and neither any Loan
       hereunder nor the ESOT Transaction constitute or shall constitute or give

              (F) ESOP Documents. The Borrower has provided the Administrative
       Agent a complete and true copy of the ESOP Plan Documents pursuant to
       which the ESOP and ESOT are maintained by the Borrower, or which concern
       the Borrower's obligations with respect to the ESOP and ESOT, as of the
       Closing Date and the ESOT Transaction Documents and has not subsequently
       amended or in any other way modified or replaced such ESOP Plan Documents
       or ESOT Transaction Documents in any manner adverse to the interests of
       the Lenders without the prior written consent of the Administrative Agent
       except for any amendment, modification or replacement required by the IRS
       or by applicable law (and the Borrower shall use its best efforts to
       deliver a copy of any such amendment, modification or replacement to the
       Agent prior to the execution thereof).

              (G) Exempt Loan. To the Borrower's knowledge, no Loan hereunder is
       for any purpose of Section 406 of ERISA or Section 4975 of the Code a
       direct or indirect loan or other transaction between the Administrative
       Agent or any of the Lenders and the ESOT which, if it is assumed that the
       Administrative Agent and Lenders are "parties in interest" and
       "disqualified persons" (as defined in Section 3(14) of ERISA and Section
       4975 of the Code), is a non-exempt prohibited transaction described in
       Section 406 of ERISA or Section 4975 of the Code.

       the Code with respect to any "disposition" by the ESOT of any shares of
       Capital Stock of the Borrower.

              (I) No Investigations. To the Borrower's knowledge, there is no
       investigation or review by any Governmental Agency, or action, suit,
       proceeding or arbitration, pending or concluded, concerning any matter
       with respect to the ESOP or ESOT relevant as to whether any
       representation set forth at Section 6.6(C) or this Section 6.21 was, or
       has or will at anytime become, inaccurate or breached or, if were to be
       made at any time prior to the satisfaction of all Obligations, would be
       inaccurate when made (other than in respect of (i) periodic requests to
       the IRS to issue a favorable determination letter to the effect that the
       ESOP is and continues to be a qualified plan and employee stock ownership
       plan and (ii) Annual Reports (IRS Form 5500 Series) for the ESOP), and
       neither the ESOP Fiduciary nor, to the best knowledge of the Borrower,
       the ESOT Trustee has made any assertion with respect to the ESOP or ESOT
       contrary to or inconsistent with the accuracy of any such representation
       which assertion could reasonably be expected to have a Material Adverse
       Effect.

the Subordinated Notes are enforceable against the holders of the Subordinated
Notes.

Government Contract has exercised any right of set-off against any Receivable
owing to the

Borrower or any Guarantor under any such Government Contract that, individually

       Effect. The Borrower will, and will cause each Material Subsidiary to,
       carry on and conduct its business in substantially the same manner and in
       substantially the same fields of enterprise as it is presently conducted
       and logical extensions thereof.

       all permits necessary for its operations and maintain such permits in
       good standing unless failure to comply or obtain such permits could not
       reasonably be expected to have a Material Adverse Effect.

       referred to in clause (i) above or claims referred to in clause (ii)
       above (and interest, penalties or fines relating thereto) need be paid if
       being contested in good faith by appropriate proceedings diligently
       instituted and conducted and if such reserve or other appropriate

       payee, and (b) all general liability and other liability policies naming
       the Administrative Agent an additional insured. In the event the Borrower

       and other supporting financial documents with respect to the business,
       financial conditions and other affairs of the Borrower and its Material
       Subsidiaries), all upon reasonable notice and at such reasonable times
       during normal business hours. Such inspections and audits described in
       the preceding sentence (i) by or on behalf of any Lender shall, unless
       occurring at a time when a Default shall be continuing, be at such
       Lender's expense and (ii) by or on behalf of the Administrative Agent,
       other than the first such inspection or audit occurring during any
       calendar year or any inspections and audits occurring at a time when a
       Default be continuing, shall be at the Administrative Agent's expense;
       all other such inspections and visitations shall be at the Borrower's

       shall comply with all Environmental, Health or Safety Requirements of
       Law, except where noncompliance will not have or is not reasonably likely
       to subject the Borrower or any of its Subsidiaries to liability,
       individually or in the aggregate, in excess of $1,000,000.

              (J) Use of Proceeds. The Borrower shall use the proceeds of the

       ESOT Transaction, for Capital Expenditures, and for the additional
       working capital needs and other general corporate purposes of the
       Borrower and its Material Subsidiaries, including, without limitation,
       the financing of Permitted Acquisitions. The Borrower will not, nor will
       it permit any Material Subsidiary to, use any of the proceeds of the
       Loans to purchase or carry any Margin Stock or to make any Acquisition,
       other than a Permitted Acquisition pursuant to Section 7.3(G).

       Subsidiaries in the form of Exhibit I-2 hereto;

              (iv) within thirty (30) days after the Administrative Agent's
       request, obtain waivers in respect of landlord's Liens on the Collateral,
       owned by such Material

       Subsidiary from each of the lessors of real property at which the
       Material Subsidiary shall maintain Collateral with a book value of
       $1,000,000 or more;

and the Borrower shall deliver to the Administrative Agent all such Pledge
Agreements, Guarantees, supplements to the Security Agreement and other
Collateral Documents, together with appropriate corporate resolutions and other
documentation (including opinions, UCC financing statements, the stock
certificates representing the Capital Stock subject to such pledge, stock powers
with respect thereto executed in blank, and such other documents as shall be
reasonably requested to perfect the Lien of such pledge) in each case in form
and substance reasonably satisfactory to the Administrative Agent, and the
Administrative Agent shall be reasonably satisfied that it has a first priority
perfected pledge of or charge over the Collateral related thereto.

              (L) Borrower and Other Collateral Documents; Intellectual Property
       Security Agreements. The Borrower shall, within thirty (30) Business Days
       of the Administrative Agent's request, use reasonable efforts to obtain

       lessors of real property at which the Borrower shall maintain Collateral.
       Within ten (10) Business Days after an Authorized Officer or legal
       officer of the Borrower has knowledge that the net book value of the
       Borrower's and its Subsidiaries' patents, trademarks, copyrights and
       other intellectual property rights shall equal or exceed $1,000,000 in
       the aggregate, the Borrower shall execute, and shall cause each
       applicable Subsidiary to execute, such Intellectual Property Security
       Agreements as shall reasonably be requested by the Administrative Agent
       to perfect a first-priority Lien in favor of the Administrative Agent,
       for the benefit of the Holders of Secured Obligations, in all such
       intellectual property.

              (M) Determination Letter. The Borrower shall promptly submit a
       request to the IRS to issue a favorable determination letter to the
       effect that the ESOP is a qualified plan and employee stock ownership
       plan within the meanings of Section 401(a) and 4975(e)(7), respectively,
       of the Code.

              (N) Hedging Agreements. Within one hundred twenty days after the
       Closing Date, the Borrower shall enter into, and shall thereafter
       maintain, Hedging Agreements on terms determined by the Borrower and
       reasonably acceptable to the Administrative Agent by which the Borrower
       is protected, by means of an interest rate swap, cap or collar, during
       the three-year period beginning on the Closing Date against increases in
       interest rates from and after the date of such contracts as to a notional
       amount of at least $17,500,000. In the event a Lender elects to enter
       into any Hedging Agreement with the Borrower, the obligations of the
       Borrower with respect to such Hedging Agreement shall be Secured
       Obligations secured by the Collateral.

              (O) Perfection Matters; Federal Assignment of Claims Act
       Compliance; Proceeds of Eligible Government Contracts. The Borrower and
       each Guarantor shall execute and deliver and pay the costs of recording

       the Assignment of Claims Act of 1940, as amended (the "GOVERNMENT
       CONTRACT ASSIGNMENTS") in connection with the assignment of payments due
       under each Government Contract, which Government Contract Assignments
       shall satisfy such requirement when executed and delivered by the
       Borrower to the Administrative Agent (and which shall not be delivered to
       any relevant Governmental Authority unless a Default shall be
       continuing); it being understood and agreed that no Government Contract
       Assignment is being required for any Government Contract which (a)(i) has
       a remaining value of less than $1,000,000 and (ii) has a remaining term
       of less than twelve (12) months or (b) expressly prohibits assignment of
       claims under the Assignment of Claims Act of 1940, as amended. The
       Borrower shall not assign payments due under any Government Contract to
       any Person other than the Administrative Agent as Collateral hereunder.

       Contract Assignments shall be borne solely by the Borrower. The Borrower
       shall use its best efforts to cause all Receivables of Government
       Contracts to be received into an account subject to the terms of the Cash
       Management Agreement or otherwise subject to control in favor of the
       Administrative Agent on terms and conditions reasonably acceptable to the

have occurred and be continuing at the date of declaration or payment thereof or
would result therefrom; provided, further, that in no event shall any Restricted
Payment be permitted under clause (v) above unless the Borrower shall have
delivered to the Administrative Agent a compliance certificate in substantially

       Material Subsidiaries on the Closing Date and any business or activities
       which are substantially similar, related or incidental thereto or logical
       extensions thereof. The Borrower shall not create, acquire or capitalize
       any Material Subsidiary after the Closing Date unless (i) no Default
       shall have occurred and be continuing or would result therefrom; (ii)
       after such creation, acquisition or capitalization, all of the
       representations and warranties contained herein shall be true and correct

       in which case, such representation or warranty shall be true and correct
       as of such date); and (iii) after such creation, acquisition or
       capitalization the Borrower and such Material Subsidiary shall comply
       with the terms of Section 7.2(K). Neither the Borrower nor its
       Subsidiaries shall make any Acquisitions, other than (a) the IITRI

              (i) no Default or Unmatured Default shall have occurred and be
       continuing or would result from such Acquisition or the incurrence of any
       Indebtedness in connection therewith;

              (ii) in the case of an Acquisition of Equity Interests of an
       entity, (x) if such Acquisition shall be consummated pursuant to a
       merger, the acquired entity shall be merged with and into the Borrower or
       any wholly-owned Subsidiary of the Borrower immediately following such

       operations of such entity shall be reported on a consolidated basis with
       the Borrower and its consolidated Subsidiaries;

              (iii) the purchase is consummated on a non-hostile basis and
       approved by the target company's board of directors (and shareholders, if

       Administrative Agent (including, without limitation, in respect of
       representations, indemnities and opinions) and the results of due
       diligence in respect of such purchase are satisfactory to the
       Administrative Agent;

              (iv) the Purchase Price for the Acquisition shall not exceed
       without the prior written consent of the Required Lenders an amount equal
       to $5,000,000 (including the incurrence or assumption of any Indebtedness
       in connection therewith), and in any event shall not exceed, together
       with all other Permitted Acquisitions permitted under this Section
       7.3(G), $10,000,000 (including the incurrence or assumption of any
       Indebtedness in connection therewith) in the aggregate during the term of
       this Agreement, and the Borrower shall have complied with all of the
       requirements of the Collateral Documents in respect thereof;

              (v) the businesses being acquired shall be substantially similar,
       related or incidental to the businesses or activities engaged in by the
       Borrower and its Subsidiaries on the Closing Date;

              (vi) effective as of the date of each such Acquisition (taking
       into account the effect of such purchase and any Indebtedness incurred in
       connection therewith), the Borrower shall deliver to the Administrative
       Agent a Borrowing Base Certificate, which Borrowing Base Certificate
       shall demonstrate that Revolving Credit Availability shall not be less
       than $7,000,000; and

              (vii) prior to each such Acquisition the Purchase Price of which
       (including the incurrence or assumption of any Indebtedness in connection
       therewith) shall be $1,000,000 or more, the Borrower shall deliver to the
       Administrative Agent and the Lenders a certificate from one of the
       Authorized Officers, demonstrating to the satisfaction of the
       Administrative Agent that after giving effect to such Acquisition and the
       incurrence of any Indebtedness permitted by Section 7.3(A) in connection
       therewith, on a pro forma basis using historical audited
       or reviewed unaudited financial statements obtained from the seller(s) in
       respect of each such Acquisition as if the Acquisition and such
       incurrence of Indebtedness had occurred on the first day of the
       twelve-month period ending on the last day of the Borrower's most
       recently completed fiscal quarter, the Borrower would have been in
       compliance with the financial covenants in Section 7.4 and not otherwise
       in Default.

              (H) Transactions with Shareholders and Affiliates. Neither the
       Borrower nor any of its Subsidiaries shall directly or indirectly enter
       into or permit to exist any transaction (including, without limitation,
       the purchase, sale, lease or exchange of any property or the rendering of
       any service) with, or make loans or advances to any holder or holders of
       any of the Equity Interests of the Borrower, or with any Affiliate of the
       Borrower or any other Person controlling or controlled by any Person that
       is the "beneficial owner" (as defined in Rule 13d-3 of the Commission
       under the Exchange Act) of greater than five percent (5%) or more of any
       class of voting securities (or other voting interests) of the Borrower or
       any of its Subsidiaries, in either case which is not a Subsidiary of the
       Borrower, on terms that are less favorable to the Borrower or any of its
       Subsidiaries, as applicable, than those that could reasonably be obtained
       in an arm's length transaction at the time from Persons who are not such
       a holder or Affiliate, except for (a) Restricted Payments permitted by
       Section 7.3(F) and Investments permitted by Section 7.3(D) (b) the
       transactions contemplated under the Asset Purchase Agreement, the ESOT
       Transaction Documents and the ESOP Plan Documents, (c) the incurrence of



                                       93
<PAGE>

       Indebtedness described in Section 7.3(A)(v) hereof, (d) sales of assets
       described in Section 7.3(B)(iii) hereof, (e) any Investment permitted by
       Section 7.3(D)(vi) hereof, and (f) any deferred compensation plans or
       arrangements, employment contracts, employee benefits, Incentive
       Arrangements and other, similar contracts or arrangements with or for the
       benefit of officers or directors of the Borrower or Subsidiaries of the
       Borrower to the extent the terms thereof are in violation of the terms of
       this Agreement or any other Loan Document.

              (I) Restriction on Fundamental Changes. Neither the Borrower nor
       any of its Subsidiaries shall enter into any merger or consolidation, or
       liquidate, wind-up or dissolve (or suffer any liquidation or
       dissolution), or convey, lease, sell, transfer or otherwise dispose of,
       in one transaction or series of transactions, all or substantially all of
       the Borrower's consolidated business or property (each such transaction a
       "FUNDAMENTAL CHANGE"), whether now or hereafter acquired, except (i)
       Fundamental Changes permitted under Sections 7.3(B), 7.3(D) or 7.3(G),
       (ii) a Subsidiary of the Borrower may be merged into or consolidated with
       the Borrower (in which case the Borrower shall be the surviving
       corporation) or any wholly-owned Subsidiary of the Borrower provided the
       Borrower owns, directly or indirectly, a percentage of the equity of the
       merged entity not less than the percentage it owned of the Subsidiary
       prior to such Fundamental Change and if the predecessor Subsidiary was a
       Guarantor, the surviving Subsidiary shall be a Guarantor hereunder, (iii)
       any liquidation of any Subsidiary of the Borrower, into the Borrower or
       another Subsidiary of the Borrower, as applicable, and (iv) upon not less
       than thirty (30) days' prior written notice to the Administrative Agent,
       any merger or reincorporation of the Borrower or any Subsidiary solely
       for purposes of reincorporation in a different jurisdiction.

              (J) Sales and Leasebacks. Neither the Borrower nor any of its
       Subsidiaries shall become liable, directly, by assumption or by
       Contingent Obligation, with respect to any lease, whether an operating
       lease or a Capitalized Lease, of any property (whether real or personal
       or mixed), (i) which it or one of its Subsidiaries sold or transferred or
       is to sell or transfer to any other Person, or (ii) which it or one of
       its Subsidiaries intends to use for substantially the same purposes as
       any other property which has been or is to be sold or transferred by it
       or one of its Subsidiaries to any other Person in connection with such
       lease, unless in either case the sale involved is not prohibited under
       Section 7.3(B) and the lease involved is not prohibited under Section
       7.3(A) and any related Investment is not prohibited under Section 7.3(D).

              (K) Margin Regulations. Neither the Borrower nor any of its
       Subsidiaries, shall use all or any portion of the proceeds of any credit
       extended under this Agreement to purchase or carry Margin Stock.

              (L) ERISA. (i) The Borrower shall not

                     (a) engage, or permit any of its Subsidiaries to engage, in
              any material prohibited transaction described in Sections 406 of
              ERISA or 4975 of the Code for which a statutory or class exemption
              is not available or a private exemption has not been previously
              obtained from the DOL;



                                       94
<PAGE>

                     (b) permit to exist any material accumulated funding
              deficiency (as defined in Sections 302 of ERISA and 412 of the
              Code), with respect to any Benefit Plan, whether or not waived;

                     (c) fail, or permit any Controlled Group member to fail, to
              pay timely required material contributions or annual installments
              due with respect to any waived funding deficiency to any Benefit
              Plan;

                     (d) terminate, or permit any Controlled Group member to
              terminate, any Benefit Plan which would result in any material
              liability of the Borrower or any Controlled Group member under
              Title IV of ERISA;

                     (e) fail to make any material contribution or payment to
              any Multiemployer Plan which the Borrower or any Controlled Group
              member may be required to make under any agreement relating to
              such Multiemployer Plan, or any law pertaining thereto;

                     (f) fail, or permit any Controlled Group member to fail, to
              pay to any Benefit Plan any required material installment or any
              other payment required under Section 412 of the Code on or before
              the due date for such installment or other payment; or

                     (g) amend, or permit any Controlled Group member to amend,
              a Benefit Plan resulting in a material increase in current
              liability for the plan year such that the Borrower or any
              Controlled Group member is required to provide security to such
              Benefit Plan under Section 401(a)(29) of the Code.

              (ii) For purposes of this Section 7.3(L), "material" means any
       noncompliance or basis for liability which could reasonably be likely to
       subject the Borrower or any of its Subsidiaries to liability,
       individually or in the aggregate, in excess of $1,000,000.

              (M) Constituent Documents. Neither the Borrower nor any of its
       Subsidiaries shall amend, modify or otherwise change any of the terms or
       provisions in any of their respective Constituent Documents as in effect
       on the Closing Date in any manner adverse to the interests of the
       Lenders, without the prior written consent of the Required Lenders other
       than to accommodate or facilitate transactions and changes otherwise
       expressly permitted by this Agreement.

              (N) Fiscal Year. Neither the Borrower nor any of its consolidated
       Subsidiaries shall change its fiscal year for accounting or tax purposes
       from a period consisting of a 52/53 calendar week year ending on
       September 30 of each year without the prior written consent of the
       Administrative Agent.

              (O) Subsidiary Covenants. The Borrower will not, and will not
       permit any Subsidiary to, create or otherwise cause to become effective
       or suffer to exist any consensual encumbrance (other than Permitted
       Liens) or restriction of any kind on the ability of any Subsidiary to pay
       dividends or make any other distribution on its stock, or



                                       95
<PAGE>

       make any other Restricted Payment, pay any Indebtedness or other
       Obligation owed to the Borrower or any other Subsidiary, make loans or
       advances or other Investments in the Borrower or any other Subsidiary, or
       sell, transfer or otherwise convey any of its property to the Borrower or
       any other Subsidiary, or merge, consolidate with or liquidate into the
       Borrower or any other Subsidiary.

              (P) Hedging Obligations. The Borrower shall not and shall not
       permit any of its Subsidiaries to enter into any Hedging Arrangements
       evidencing Hedging Obligations, other than Hedging Arrangements entered
       into by the Borrower or its Subsidiaries pursuant to which the Borrower
       or its Subsidiaries has hedged its actual or anticipated interest rate,
       foreign currency or commodity exposure, and which are non-speculative in
       nature. The agreements in respect of such permitted Hedging Arrangements
       entered into by the Borrower or its Subsidiaries and any Lender or any
       affiliate of any Lender including, without limitation, to hedge floating
       interest rate risk in an aggregate notional amount not to exceed at any
       time an amount equal to the outstanding balance of the Term Loans at such
       time are sometimes referred to herein as "Hedging Agreements." In the
       event a Lender or any of its Affiliates elects to enter into any Hedging
       Agreement with the Borrower or any of its Subsidiaries, the obligations
       of the Borrower and such Subsidiary with respect to such Hedging
       Agreement shall be Secured Obligations secured by the Collateral.

              (Q) Intercompany Loans. Neither the Borrower nor any of its
       Subsidiaries shall make any loans to any other Subsidiary of the Borrower
       except to the extent any such loans shall be evidenced by promissory
       notes which provide that (i) if any acceleration of the Obligations under
       this Agreement shall occur, the obligations under such promissory note
       shall immediately become due and payable without any election or action
       on the part of such Person, and (ii) such promissory notes shall be
       pledged to the Administrative Agent pursuant to the terms of the
       Collateral Documents.

              (R) Issuance of Disqualified Stock. From and after the Closing
       Date, neither the Borrower, nor any of its Subsidiaries shall issue any
       Disqualified Stock. All issued and outstanding Disqualified Stock shall
       be treated as Consolidated Total Indebtedness for all purposes of this
       Agreement (and as funded Indebtedness for purposes of Section 7.1(F)),
       and the amount of such deemed Indebtedness shall be the aggregate amount
       of the liquidation preference of such Disqualified Stock.

              (S) Loss of S Corporation Status. The Borrower shall not fail to
       be qualified as an "S corporation" as defined in Section 1361 of the Code
       at all times on or after the Closing Date.

              (T) Imposition of UBIT on ESOT. The ESOT shall not be subject to
       tax imposed under the Code with respect to any item of income or loss of
       the Borrower or any Subsidiary of the Borrower at any time on or after
       the Closing Date that could reasonably be anticipated to result in tax
       liability to the ESOT, the Borrower or any of its Subsidiaries in an
       amount in excess of $1,000,000.



                                       96
<PAGE>

              (U) ESOP Conflict. The Borrower shall not permit the performance
       of any of the Transaction Documents to which the ESOT is a party to
       conflict with the ESOP Plan Documents, conflict with any Requirement of
       Law, or require the registration with, consent or approval of, or notice
       to, or other action to, with or by any Governmental Authority other than
       (i) filings that are made regarding the status of the Borrower as an "S
       Corporation" as such term is defined in Section 1361 of the Code, which
       filings shall have been made on or prior to the Closing Date, (ii)
       filings as required by Section 7.2(M) and subsequent requests to the IRS
       to issue a favorable determination letter to the effect that the ESOP is
       and continues to be such a qualified plan and employee stock ownership
       plan, and (iii) Annual Reports (IRS Form 5500 series) for the ESOP.

              (V) Assets as Plan Assets. The Borrower shall not permit any of
       the assets of the Borrower to constitute, for any purpose of ERISA or
       Section 4975 of the Code, assets of the ESOP or any other "plan" as
       defined in Section 3(3) of ERISA or Section 4975 of the Code.

              (W) Prohibited Transaction. The Borrower shall not permit any
       material non-exempt prohibited transaction described in Section 406 of
       ERISA or Section 4975 of the Code to occur with respect to the ESOP.

              (X) Non-Qualification of ESOP. The Borrower shall not take any
       action, nor fail to take any action, the result of which action or
       inaction is that the ESOP shall fail to be qualified under Section 401(a)
       of the Code. The Borrower shall not permit the ESOP to fail to be an
       employee stock ownership plan as defined in Section 4975(e)(7) of the
       Code.

              (Y) Excise Tax. The Borrower and its Subsidiaries shall not be
       subject to the tax imposed by Section 4978 of the Code with respect to
       any "disposition" by the ESOT of any shares of Capital Stock of the
       Borrower occurring as a result of the ESOT Transaction.

              (Z) Lender/ESOT Transactions. No Loan hereunder shall for any
       purpose of Section 406 of ERISA or Section 4975 of the Code be a direct
       or indirect loan or other transaction between the Administrative Agent or
       any of the Lenders and the ESOT which, if it is assumed that the
       Administrative Agent and Lenders are "parties in interest" and
       "disqualified persons" (as defined in Section 3(14) of ERISA and Section
       4975 of the Code), is a non-exempt prohibited transaction described in
       Section 406 of ERISA or Section 4975 of the Code.

              (AA) ERISA Judgments and Determinations. There shall be no
       finding, holding, ruling or other determination not subject to cure made
       by any court or Governmental Authority, and there shall be no assertion
       by the ESOP Fiduciary or, to the best knowledge of the Borrower, the ESOT
       Trustee, concerning any matter with respect to the ESOP or ESOT contrary
       to or inconsistent with any covenant set forth in Section 7.3(S) through
       (Z) which assertion could reasonably be expected to have a Material
       Adverse Effect.

              (BB) Subordinated Indebtedness. The Borrower shall not and shall
       not permit any of its Subsidiaries to amend, supplement or modify the
       terms of the Subordinated Notes or the Securities Purchase Agreements, or
       make any payment required as a result of an amendment or change thereto,
       other than amendments, supplements or modifications which (i) (a)
       decrease the rate of interest payable on the Subordinated Notes, (b)
       provide for the payment in kind in lieu of cash of any portion of the
       interest on the Subordinated Notes, (c) provide for the extension of the
       maturity date with respect to any principal or interest payment to be
       made under the Subordinated Notes, (d) provide more flexibility to the
       Borrower or its Subsidiaries in connection with any covenants or (e)
       waive any defaults existing in connection with the Subordinated Notes or
       the Securities Purchase Agreements and (ii) do not adversely affect in
       any material respect the interests of the Administrative Agent or any
       Lender.

              7.4 Financial Covenants. The Borrower shall comply with the
following (provided that for purposes of calculating the following financial
covenants, EBITDAE shall be deemed to be equal to (i) $3,707,773 for the fiscal

July 5, 2002, and (iii) $5,487,256 for the fiscal quarter ending September 30,

              (A) Maximum Senior Leverage Ratio. The Borrower shall not permit
       the ratio (the "SENIOR LEVERAGE RATIO") of (i) the sum of the aggregate
       outstanding principal amount of all Term Loans and Revolving Credit
       Obligations to (ii) EBITDAE to be greater than:

              (i) 2.75 to 1.00 as of the end of each fiscal quarter for the
       period commencing with the fiscal quarter ending December 20, 2002
       through the fiscal quarter ending September 30, 2003;

              (ii) 2.50 to 1.00 as of the end of each fiscal quarter for the

       through the fiscal quarter ending September 30, 2004;

              (iii) 2.00 to 1.00 as of the end of each fiscal quarter for the

              (v) 1.30 to 1.00 as of the end of each fiscal quarter thereafter.

The Senior Leverage Ratio shall be calculated, in each case, as of the last day
of each fiscal quarter based upon (a) for Term Loans and Revolving Credit
Obligations, the principal amount of Term Loans and Revolving Credit Obligations
as of the last day of each such fiscal quarter; and (b) for EBITDAE, the actual
amount for the four-quarter period ending on such last day of such fiscal
quarter, taking into account Permitted Acquisitions and calculated, with respect

financial statements obtained from the seller(s) in such Permitted Acquisitions
(adjusted for non-recurring seller expenses and other add-backs to EBITDAE, in
each case, agreed upon by the Borrower and the Administrative Agent) and
reasonably acceptable to the Administrative Agent, broken down by fiscal quarter
in the Borrower's reasonable judgment and satisfactory to the Administrative
Agent.

              (B) Maximum Leverage Ratio. The Borrower shall not permit the
       ratio (the "LEVERAGE RATIO") of (i) the principal amount of Consolidated
       Total Indebtedness (other than the Junior Subordinated Notes) to (ii)
       EBITDAE to be greater than:

              (i) 4.00 to 1.00 as of the end of each fiscal quarter for the
       period commencing with the fiscal quarter ending December 20, 2002
       through the fiscal quarter ending September 30, 2003;

              (ii) 3.60 to 1.00 as of the end of each fiscal quarter for the

              (iii) 3.25 to 1.00 as of the end of each fiscal quarter for the

       through the fiscal quarter ending September 30, 2005;

              (iv) 3.00 to 1.00 as of the end of each fiscal quarter for the
       period commencing with the fiscal quarter ending December 16, 2005
       through the fiscal quarter ending September 30, 2006;

              (v) 2.50 to 1.00 as of the end of each fiscal quarter thereafter.

The Leverage Ratio shall be calculated, in each case, as of the last day of each
fiscal quarter based upon (a) for Consolidated Total Indebtedness, the principal
amount of Consolidated Total Indebtedness as of the last day of each such fiscal
quarter; and (b) for EBITDAE, the actual amount for the four-quarter period
ending on such last day of such fiscal quarter, taking into account Permitted
Acquisitions and calculated, with respect to Permitted Acquisitions, on a pro
forma basis using historical audited and reviewed unaudited financial statements
obtained from the seller(s) in such Permitted Acquisitions (adjusted for
non-recurring seller expenses and other add-backs to EBITDAE, in each case,
agreed upon by the Borrower and the Administrative Agent) and reasonably
acceptable to the Administrative Agent, broken down by fiscal quarter in the
Borrower's reasonable judgment and satisfactory to the Administrative Agent.

              (C) Minimum Fixed Charge Coverage Ratio. The Borrower and its
       consolidated Subsidiaries shall maintain a ratio ("FIXED CHARGE COVERAGE
       RATIO") of (i) EBITDAE for such period minus Capital Expenditures for
       such period, to (ii) the sum of the amounts of (a) scheduled amortization
       during such period of the principal portion of the Term Loans and
       scheduled amortization during such period of the principal portion of all
       other Consolidated Total Indebtedness, plus (b) Restricted Payments paid
       in cash and, if positive, net ESOP repurchase obligations during such
       period, plus (c) all charges for foreign, federal, state and local income
       taxes paid in cash by the Borrower and its consolidated Subsidiaries
       during such period, plus (d) Cash Interest Expense during such



                                       99

       period plus (e) cash payments in respect of purchase price adjustments,
       earn-outs or other similar forms of contingent purchase price during such
       period (exclusive of cash purchase price adjustments related to the IITRI
       Acquisition paid on the Closing Date), of at least (1) 1.20 to 1.00 as of
       the end of each fiscal quarter for the period commencing with the fiscal
       quarter ending on December 20, 2002 through the fiscal quarter ending
       September 30, 2003; (2) 1.25 to 1.00 as of the end of each fiscal quarter
       for the period commencing with the fiscal quarter ending on December 19,
       2003 through the fiscal quarter ending March 10, 2006; and (3) 1.35 to
       1.00 as of the end of each fiscal quarter thereafter.

              In each case, the Fixed Charge Coverage Ratio shall be determined
       as of the last day of each fiscal quarter for the four fiscal quarter
       period ending on such last day of such fiscal quarter, taking into
       account Permitted Acquisitions and calculated, with respect to Permitted
       Acquisitions, on a pro forma basis using historical audited and reviewed
       unaudited financial statements obtained from the seller(s) in such
       Permitted Acquisitions (adjusted for non-recurring seller expenses and
       other add-backs to EBITDAE, in each case, agreed upon by the Borrower and
       the Administrative Agent) and reasonably acceptable to the Administrative
       Agent, broken down by fiscal quarter in the Borrower's reasonable
       judgment and satisfactory to the Administrative Agent.

Lender affected thereby:

              (A)  Postpone or extend the Revolving Loan Termination Date or the
        Term Loan Final Maturity Date or any other date fixed for any payment of
        principal of, or interest on, the Loans, the Reimbursement Obligations
        or any fees or other amounts payable to such Lender (except with respect
        to (i) any modifications of the provisions relating to amounts, timing
        or application of prepayments of Loans and other Obligations, which
        modification shall require only the approval of the Required Lenders
        (other than the provisions relating to the amounts, timing or
        application of prepayments of the Term Loans which modifications shall
        also require the approval of Term Loan Lenders with sixty-six and
        two-thirds percent (66 2/3%) or more of the then outstanding Term Loans)
        and (ii) a waiver of the application of the default rate of interest
        pursuant to Section 2.11 hereof which waiver shall require only the
        approval of the Required Lenders).

              (B)  Reduce the principal amount of any Loans or L/C Obligations,
        or reduce the rate or extend the time of payment of interest or fees
        thereon (other than (i) a waiver of the application of the default rate
        of interest pursuant to Section 2.11 hereof, and (ii) as a result of a
        change in the definition of Leverage Ratio or any of the components
        thereof or the method of calculation thereof).

              (C)  Reduce the percentage specified in the definition of Required
        Lenders or any other percentage of Lenders specified to be the
        applicable percentage in this Agreement to act on specified matters or
        amend the definitions of "Required Lenders", "Revolving Loan Pro Rata
        Share", "Term Loan Pro Rata Share," or "Pro Rata Share".

              (D)  Increase the amount of the Revolving Loan Commitment or Term
        Loan Commitment of any Lender hereunder or increase any Lender's
        Revolving Loan Pro Rata Share, Term Loan Pro Rata Share or Pro Rata
        Share (except with respect to an increase in the amount, or other
        modification to the terms or components, of the Borrowing Base (Monthly)
        or Borrowing Base (Senior Debt)).

              (E)  Permit the Borrower to assign its rights under this
        Agreement.

              (F)  Other than pursuant to a transaction permitted by the terms
        of this Agreement, release all or substantially all of the Collateral
        which is subject to any Loan Document.

              (G)  Other than pursuant to a transaction permitted by the terms
        of this Agreement, release any guarantor from its obligations under the
        Guaranty.

              (H)  Amend Section 7.2(K), Section 12.2, Section 12.3 or this
        Section 9.1.

No amendment of any provision of this Agreement relating to (i) the
Administrative Agent shall be effective without the written consent of the
Administrative Agent, (ii) Swing Line Loans shall be effective without the
written consent of the Swing Line Bank and (iii) any Issuing Bank shall be
effective without the written consent of such Issuing Bank. The Administrative
Agent may waive payment of the fee required under Section 13.3(B) without
obtaining the consent of any of the Lenders. The Administrative Agent shall not
enter into any amendment or other modification of any subordination agreement in
respect of the Subordinated Notes without the prior consent of the Required
Lenders.

              9.2  Preservation of Rights. No delay or omission of the Lenders
or the Administrative Agent to exercise any right under the Loan Documents shall
impair such right or be construed to be a waiver of any Default or an
acquiescence therein, and the making of a Loan or the issuance of a Letter of
Credit notwithstanding the existence of a Default or the inability of the
Borrower to satisfy the conditions precedent to such Loan or issuance of such
Letter of Credit shall not constitute any waiver or acquiescence. Any single or
partial exercise of any such right shall not preclude other or further exercise
thereof or the exercise of any other right, and no waiver, amendment or other
variation of the terms, conditions or provisions of the Loan Documents
whatsoever shall be valid unless in writing signed by the requisite number of
Lenders required pursuant to Section 9.1, and then only to the extent in such
writing specifically set forth. All remedies contained in the Loan Documents or
by law afforded shall be cumulative and all shall be available to the
Administrative Agent and the Lenders until all of the Termination Conditions
shall have been satisfied.

                   ARTICLE X: GENERAL PROVISIONS

              10.1 Survival of Representations. All representations and
warranties of the Borrower contained in this Agreement shall survive delivery of
this Agreement and the making of the Loans herein contemplated so long as any
principal, accrued interest, fees, or any other amount due and payable under any
Loan Document is outstanding and unpaid (other than contingent reimbursement and
indemnification obligations) and so long as the Commitments have not been
terminated.

                                      106

              10.2 Governmental Regulation. Anything contained in this Agreement
to the contrary notwithstanding, no Lender shall be obligated to extend credit
to the Borrower in violation of any limitation or prohibition provided by any
applicable statute or regulation.

              10.3 Performance of Obligations. The Borrower agrees that the
Administrative Agent may, but shall have no obligation to (i) at any time, pay
or discharge taxes, liens, security interests or other encumbrances levied or
placed on or threatened against any property of the Borrower (including, without
limitation, the Collateral) to the extent the Borrower is required by the terms
hereof to pay any such amount, but has not done so (other than such taxes,
liens, security interests or other encumbrances as shall be actively and in good
faith contested by the Borrower and in respect of which the Borrower shall have
established reserves in accordance with Agreement Accounting Principles to the
extent such taxes, liens, security interests or other encumbrances would
otherwise be permitted hereunder) and (ii), after the occurrence and during the
continuance of a Default, to make any other payment or perform any act required
of the Borrower under any Loan Document or take any other action which the
Administrative Agent in its discretion deems necessary or desirable to protect
or preserve such property of the Borrower. The Administrative Agent shall use
its reasonable efforts to give the Borrower notice of any action taken under
this Section 10.3 prior to the taking of such action or promptly thereafter
provided the failure to give such notice shall not affect the Borrower's
obligations in respect thereof. The Borrower agrees to pay the Administrative
Agent, upon demand, the principal amount of all funds advanced by the
Administrative Agent under this Section 10.3, together with interest thereon at
the rate from time to time applicable to Floating Rate Loans from the date of
such advance until the outstanding principal balance thereof is paid in full. If
the Borrower fails to make payment in respect of any such advance under this
Section 10.3 within one (1) Business Day after the date the Borrower receives
written demand therefor from the Administrative Agent, the Administrative Agent
shall promptly notify each Lender and each Lender agrees that it shall thereupon
make available to the Administrative Agent, in Dollars in immediately available
funds, the amount equal to such Lender's Pro Rata Share of such advance. If such
funds are not made available to the Administrative Agent by such Lender within
one (1) Business Day after the Administrative Agent's demand therefor, the
Administrative Agent will be entitled to recover any such amount from such
Lender together with interest thereon at the Federal Funds Effective Rate for
each day during the period commencing on the date of such demand and ending on
the date such amount is received. The failure of any Lender to make available to
the Administrative Agent its Pro Rata Share of any such unreimbursed advance
under this Section 10.3 shall neither relieve any other Lender of its obligation
hereunder to make available to the Administrative Agent such other Lender's Pro
Rata Share of such advance on the date such payment is to be made nor increase
the obligation of any other Lender to make such payment to the Administrative
Agent. All outstanding principal of, and interest on, advances made under this
Section 10.3 shall constitute Obligations secured by the Collateral until paid
in full by the Borrower.

              10.4 Headings. Section headings in the Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of the Loan Documents.

              10.5 Entire Agreement. The Loan Documents and the letter agreement
between the Administrative Agent and the Borrower dated May 23, 2002 embody the
entire

                                      107

<PAGE>

agreement and understanding among the Borrower, the Administrative Agent and the
Lenders and supersede all prior agreements and understandings among the
Borrower, the Administrative Agent and the Lenders relating to the subject
matter thereof.

              10.6 Several Obligations; Benefits of this Agreement. The
respective obligations of the Lenders hereunder are several and not joint and no
Lender shall be the partner or agent of any other Lender (except to the extent
to which the Administrative Agent is authorized to act as such). The failure of
any Lender to perform any of its obligations hereunder shall not relieve any
other Lender from any of its obligations hereunder. This Agreement shall not be
construed so as to confer any right or benefit upon any Person other than the
parties to this Agreement and their respective successors and assigns.

              10.7 Expenses; Indemnification.

              (A)  Expenses. The Borrower shall reimburse the Administrative
        Agent and the Arranger for any reasonable costs, and out-of-pocket
        expenses (including reasonable attorneys' and paralegals' fees and time
        charges of attorneys and paralegals for the Administrative Agent, paid
        or incurred by the Administrative Agent or the Arranger in connection
        with the preparation, negotiation, execution, delivery, syndication,
        distribution (including, via the internet), review, amendment,
        modification, and administration of the Loan Documents. The Borrower
        also agrees to reimburse the Administrative Agent and the Arranger and
        the Lenders for any costs, and out-of-pocket expenses (including
        reasonable attorneys' and paralegals' fees and time charges of attorneys
        and paralegals for the Administrative Agent and the Arranger and the
        Lenders) paid or incurred by the Administrative Agent or the Arranger or
        any Lender in connection with the collection of the Obligations and
        enforcement of their rights and remedies under the Loan Documents. In
        addition to expenses set forth above, the Borrower agrees to reimburse
        the Administrative Agent, promptly after the Administrative Agent's
        request therefor, for each audit, or other business analysis conducted
        in accordance with the terms hereof and performed by or for the benefit
        of the Lenders in connection with this Agreement or the other Loan
        Documents in an amount equal to the Administrative Agent's then
        customary charges for each person employed to perform such audit or
        analysis, plus all reasonable costs and expenses (including without
        limitation, travel expenses) incurred by the Administrative Agent in the
        performance of such audits or analysis. Administrative Agent shall
        provide the Borrower with a detailed statement of all reimbursements
        requested under this Section 10.7(A).

              (B)  Indemnity. The Borrower further agrees to defend, protect and
        indemnify the Administrative Agent, the Arranger and each and all of the
        Lenders and each of their respective Affiliates extending financial
        accommodations pursuant to any of the Loan Documents, and each of such
        Administrative Agent's, Arranger's, Lender's, or Affiliate's respective
        officers, directors, trustees, investment advisors, employees, attorneys
        and agents (including, without limitation, those retained in connection
        with the satisfaction or attempted satisfaction of any of the conditions
        set forth in Article V) (collectively, the "INDEMNITEES") from and
        against any and all liabilities, obligations, losses, damages,
        penalties, actions, judgments, suits, claims, costs, expenses of any
        kind or nature whatsoever (including, without limitation, the reasonable
        fees and disbursements of

                                      108

<PAGE>

        counsel for such Indemnitees in connection with any investigative,
        administrative or judicial proceeding), imposed on, incurred by, or
        asserted against such Indemnitees in any manner relating to or arising
        out of:

              (i)  this Agreement or any of the other Loan Documents or any of
           the Transaction Documents, or any act, event or transaction related
           or attendant thereto or to the IITRI Acquisition, the ESOT
           Transaction, the making of the Loans, and the issuance of and
           participation in Letters of Credit hereunder, the management of such
           Loans or Letters of Credit, the use or intended use of the proceeds
           of the Loans or Letters of Credit hereunder, or any of the other
           transactions contemplated by the Transaction Documents; or

              (ii) any costs, liabilities, obligations, responsibilities,
           losses, damages, personal injury, death, punitive damages, economic
           damages, consequential damages, treble damages, intentional, willful
           or wanton injury, damage or threat to the environment, natural
           resources or public health or welfare, costs and expenses (including,
           without limitation, reasonable attorney, expert and consulting fees
           and costs of investigation, feasibility or remedial action studies),
           fines, penalties and monetary sanctions, interest, direct or
           indirect, known or unknown, absolute or contingent, past, present or
           future relating to the violation or alleged violation of any
           Environmental, Health or Safety Requirements of Law arising from or
           in connection with the past, present or future operations of the
           Borrower, its Subsidiaries or any of their respective predecessors in
           interest, or, the past, present or future environmental, health or
           safety condition of any respective property of the Borrower or its
           Subsidiaries, the presence of asbestos-containing materials at any
           respective property of the Borrower or its Subsidiaries or the
           Release or threatened Release of any Contaminant into the environment
           (collectively, the "INDEMNIFIED MATTERS");

provided, however, the Borrower shall have no obligation to an Indemnitee
hereunder (i) with respect to Indemnified Matters caused solely by or resulting
solely from the willful misconduct or Gross Negligence of such Indemnitee with
respect to the Loan Documents, as determined by the final non-appealed judgment
of a court of competent jurisdiction, or (ii) for reimbursement of amounts
asserted against any Indemnitee by the Borrower, any of its Subsidiaries or any
other Indemnitee (each a "Claimant") and paid by such Indemnitee on any final,
non-appealable judgement in the Claimant's favor against such Indemnitee by a
court of competent jurisdiction. If the undertaking to indemnify and pay set
forth in the preceding sentence may be unenforceable because it is violative of
any law or public policy, the Borrower shall contribute the maximum portion
which it is permitted to pay and satisfy under applicable law, to the payment
and satisfaction of all Indemnified Matters incurred by the Indemnitees.

              (C) Waiver of Certain Claims; Settlement of Claims. The Borrower
        further agrees to assert no claim against any of the Indemnitees on any
        theory of liability seeking consequential, special, indirect, exemplary
        or punitive damages. No settlement shall be entered into by the Borrower
        or any of its Subsidiaries with respect to any claim, litigation,
        arbitration or other proceeding relating to the Indemnified Matters
        (whether or not the Administrative Agent or any Lender or any Indemnitee
        is a party thereto) unless such settlement releases all Indemnitees from
        any and all liability with respect thereto.

              (D) Survival of Agreements. The obligations and agreements of the
        Borrower under this Section 10.7 shall survive the termination of this
        Agreement.

              10.8 Numbers of Documents. All statements, notices, closing
documents, and requests hereunder shall be furnished to the Administrative Agent
with sufficient counterparts so that the Administrative Agent may furnish one to
each of the Lenders.

              10.9 Accounting. Except as provided to the contrary herein, all
accounting terms used herein shall be interpreted and all accounting
determinations hereunder shall be made in accordance with Agreement Accounting
Principles.

              If any changes in generally accepted accounting principles are
hereafter required or permitted and are adopted by the Borrower or any of its
Subsidiaries with the agreement of its independent certified public accountants
and such changes result in a change in the method of calculation of any of the
financial covenants, tests, restrictions or standards herein or in the related
definitions or terms used therein ("Accounting Changes"), the parties hereto
agree, at the Borrower's request, to enter into negotiations, in good faith, in
order to amend such provisions in a credit neutral manner so as to reflect
equitably such changes with the desired result that the criteria for evaluating
the Borrower's and its Subsidiaries' financial condition shall be the same in
all material respects after such changes as if such changes had not been made;
provided, however, that no accounting change shall be given effect in such
calculations until such provisions are amended in a manner reasonably
satisfactory to the Required Lenders. In the event such amendment is entered
into, all references in this Agreement to Agreement Accounting Principles means
generally accepted accounting principles as of the date of such amendment. After
the occurrence of any such accounting change but until such time as such
amendment has been entered into, all financial statements and other financial
reports required to be delivered under this Agreement shall be prepared and
delivered in accordance with Agreement Accounting Principles.

              10.10 Severability of Provisions. Any provision in any Loan
Document that is held to be inoperative, unenforceable, or invalid in any
jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or
invalid without affecting the remaining provisions in that jurisdiction or the
operation, enforceability, or validity of that provision in any other
jurisdiction, and to this end the provisions of all Loan Documents are declared
to be severable.

              10.11 Nonliability of Lenders. The relationship between the
Borrower and the Lenders and the Administrative Agent shall be solely that of
borrower and lender. Neither the Administrative Agent nor any Lender shall have
any fiduciary responsibilities to the Borrower. Neither the Administrative Agent
nor any Lender undertakes any responsibility to the Borrower to review or inform
the Borrower of any matter in connection with any phase of the Borrower's
business or operations.

              10.12 GOVERNING LAW. ANY DISPUTE BETWEEN THE BORROWER AND ANY
AGENT, ANY LENDER OR ANY OTHER HOLDER OF SECURED OBLIGATIONS ARISING OUT OF,
CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED
BETWEEN THEM IN CONNECTION WITH, THIS AGREEMENT OR ANY OF THE OTHER LOAN

<PAGE>

DOCUMENTS, SHALL BE RESOLVED IN ACCORDANCE WITH THE INTERNAL LAWS (INCLUDING
Section 735 ILCS 105/5-1 ET SEQ., BUT OTHERWISE WITHOUT REGARD TO THE CONFLICTS

VOLUNTARILY ELECTED THAT THIS AGREEMENT, THE OTHER LOAN DOCUMENTS AND ALL LOANS
BE GOVERNED BY THE LAWS OF THE STATE OF ILLINOIS, WHICH IS THE PRINCIPAL PLACE
OF BUSINESS OF THE ADMINISTRATIVE AGENT.

              10.13 CONSENT TO JURISDICTION; SERVICE OF PROCESS; JURY TRIAL.


              (A) NON-EXCLUSIVE JURISDICTION. EXCEPT AS PROVIDED IN SUBSECTION
        (B), EACH OF THE PARTIES HERETO AGREES AND ACCEPTS FOR ALL DISPUTES
        AMONG THEM ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO
        THE RELATIONSHIP ESTABLISHED AMONG THEM IN CONNECTION WITH, THIS
        AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS THE NON-EXCLUSIVE
        JURISDICTION OF THE STATE OR FEDERAL COURTS LOCATED IN CHICAGO,
        ILLINOIS, BUT THE PARTIES HERETO ACKNOWLEDGE THAT ANY APPEALS FROM THOSE
        COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF CHICAGO,
        ILLINOIS. EACH OF THE PARTIES HERETO WAIVES IN ALL DISPUTES BROUGHT
        PURSUANT TO THIS SUBSECTION (A) ANY OBJECTION THAT IT MAY HAVE TO THE
        LOCATION OF THE COURT CONSIDERING THE DISPUTE.

              (B) OTHER JURISDICTIONS. THE BORROWER AGREES THAT THE
        ADMINISTRATIVE AGENT, ANY LENDER OR ANY OTHER HOLDER OF SECURED
        OBLIGATIONS SHALL HAVE THE RIGHT TO PROCEED AGAINST THE BORROWER OR ITS
        RESPECTIVE PROPERTY IN A COURT IN ANY LOCATION TO ENABLE SUCH PERSON TO
        (1) OBTAIN PERSONAL JURISDICTION OVER THE BORROWER OR (2) REALIZE ON THE
        COLLATERAL, OR (3) IN ORDER TO ENFORCE A JUDGMENT OR OTHER COURT ORDER
        ENTERED IN FAVOR OF SUCH PERSON. THE BORROWER AGREES THAT IT WILL NOT
        ASSERT ANY PERMISSIVE COUNTERCLAIMS IN ANY PROCEEDING THAT IS SEPARATE
        FROM ANY PROCEEDING BROUGHT UNDER CLAUSE (A) ABOVE AND THAT IS BROUGHT
        BY SUCH PERSON SOLELY TO REALIZE ON ANY SECURITY FOR THE OBLIGATIONS OR
        TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF SUCH PERSON. THE
        BORROWER WAIVES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE
        COURT IN WHICH SUCH PERSON HAS COMMENCED A PROCEEDING DESCRIBED IN THIS
        SUBSECTION (B).

              (C) SERVICE OF PROCESS. NOTHING HEREIN SHALL IN ANY WAY BE DEEMED
        TO LIMIT THE ABILITY OF ANY AGENT OR THE HOLDERS OF THE OBLIGATIONS TO
        SERVE ANY WRITS, SERVICE OF PROCESS OR SUMMONSES IN ANY SUIT, ACTION OR
        PROCEEDING ISSUED BY ANY


                                      111

<PAGE>

        COURT REFERRED TO IN THIS SECTION 10.13 IN ANY MANNER PERMITTED BY
        APPLICABLE LAW.

              (D) WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO IRREVOCABLY
        WAIVES ANY RIGHT TO HAVE A JURY PARTICIPATE IN RESOLVING ANY DISPUTE,
        ARISING OUT OF, CONNECTED WITH, RELATED TO OR INCIDENTAL TO THIS
        AGREEMENT OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR
        DELIVERED IN CONNECTION HEREWITH. EACH OF THE PARTIES HERETO AGREES AND
        CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE
        DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT ANY PARTY HERETO MAY FILE
        AN ORIGINAL COUNTERPART OR A COPY OF THIS AGREEMENT WITH ANY COURT AS
        WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF
        THEIR RIGHT TO TRIAL BY JURY.

              (E) ADVICE OF COUNSEL. EACH OF THE PARTIES REPRESENTS TO EACH
        OTHER PARTY HERETO THAT IT HAS DISCUSSED THIS AGREEMENT AND,
        SPECIFICALLY, THE PROVISIONS OF SECTION 10.7 AND THIS SECTION 10.13,
        WITH ITS COUNSEL.

              10.14 Other Transactions. Each of the Administrative Agent, the
Arranger, the Lenders, the Swing Line Bank, the Issuing Banks and the Borrower
acknowledge that the Lenders (or Affiliates of the Lenders) may, from time to
time, effect transactions for their own accounts or the accounts of customers,
and hold positions in loans or options on loans of the Borrower, the Borrower's
Subsidiaries and other companies that may be the subject of this credit
arrangement and nothing in this Agreement shall impair the right of any such
Person to enter into any such transaction (to the extent it is not expressly
prohibited by the terms of this Agreement) or give any other Person any claim or
right of action hereunder as a result of the existence of the credit
arrangements hereunder, all of which are hereby waived. In addition, certain
Affiliates of one or more of the Lenders are or may be securities firms and as
such may effect, from time to time, transactions for their own accounts or for
the accounts of customers and hold positions in securities or options on
securities of the Borrower, the Borrower's Subsidiaries and other companies that
may be the subject of this credit arrangement and nothing in this Agreement
shall impair the right of any such Person to enter into any such transaction (to
the extent it is not expressly prohibited by the terms of this Agreement) or
give any other Person any claim or right of action hereunder as a result of the
existence of the credit arrangements hereunder, all of which are hereby waived.
Each of the Administrative Agent, the Arranger, the Lenders, the Swing Line
Bank, the Issuing Banks and the Borrower acknowledges and consents to these
multiple roles, and further acknowledges that the fact that any such unit or
Affiliate is providing another service or product or proposal therefor to the
Borrower or any of its Subsidiaries does not mean that such service, product, or
proposal is or will be acceptable to any of the Administrative Agent, the
Arranger, the Lenders, the Swing Line Bank or the Issuing Banks.

              10.15 Subordination of Intercompany Indebtedness. The Borrower
agrees that any and all claims of the Borrower against any of its Subsidiaries
that is a Guarantor with respect to any "Intercompany Indebtedness" (as
hereinafter defined), any endorser, obligor or any other


                                      112
<PAGE>



guarantor of all or any part of the Obligations, or against any of its
properties shall be subordinate and subject in right of payment to the prior
payment, in full and in cash, of all Obligations and Hedging Obligations under
Hedging Arrangements entered into with the Lenders or any of their Affiliates
("DESIGNATED HEDGING AGREEMENTS"); provided that, and not in contravention of
the foregoing, so long as no Default has occurred and is continuing the Borrower
may make loans to and receive payments in the ordinary course with respect to
such Intercompany Indebtedness from each such Guarantor to the extent not
prohibited by the terms of this Agreement and the other Loan Documents.
Notwithstanding any right of the Borrower to ask, demand, sue for, take or
receive any payment from any Guarantor, all rights, liens and security interests
of the Borrower, whether now or hereafter arising and howsoever existing, in any
assets of any Guarantor shall be and are subordinated to the rights of the
holders of the Obligations and the Administrative Agent in those assets. The
Borrower shall have no right to possession of any such asset or to foreclose
upon any such asset, whether by judicial action or otherwise, unless and until
all of the Obligations (other than contingent indemnity obligations) and the
Hedging Obligations under Designated Hedging Agreements shall have been fully
paid and satisfied (in cash) and all financing arrangements pursuant to any Loan
Document or Designated Hedging Agreement have been terminated. If all or any
part of the assets of any Guarantor, or the proceeds thereof, are subject to any
distribution, division or application to the creditors of such Guarantor,
whether partial or complete, voluntary or involuntary, and whether by reason of
liquidation, bankruptcy, arrangement, receivership, assignment for the benefit
of creditors or any other action or proceeding, or if the business of any such
Guarantor is dissolved or if substantially all of the assets of any such
Guarantor are sold, then, and in any such event (such events being herein
referred to as an "INSOLVENCY EVENT"), any payment or distribution of any kind
or character, either in cash, securities or other property, which shall be
payable or deliverable upon or with respect to any indebtedness of any Guarantor
to the Borrower ("INTERCOMPANY INDEBTEDNESS") shall be paid or delivered
directly to the Administrative Agent for application on any of the Obligations
and the Hedging Obligations under Designated Hedging Agreements, due or to
become due, until such Obligations or Hedging Obligations (other than contingent
indemnity obligations) shall have first been fully paid and satisfied (in cash).
Should any payment, distribution, security or instrument or proceeds thereof be
received by the Borrower upon or with respect to the Intercompany Indebtedness
after an Insolvency Event prior to the satisfaction of all of the Obligations
(other than contingent indemnity obligations) and the Hedging Obligations under
Designated Hedging Agreements and the termination of all financing arrangements
pursuant to any Loan Document and/or Designated Hedging Agreement, the Borrower
shall receive and hold the same in trust, as trustee, for the benefit of the
holders of the Obligations and such Hedging Obligations and shall forthwith
deliver the same to the Administrative Agent, for the benefit of such Persons,
in precisely the form received (except for the endorsement or assignment of the
Borrower where necessary), for application to any of the Obligations and such
Hedging Obligations, due or not due, and, until so delivered, the same shall be
held in trust by the Borrower as the property of the holders of the Obligations
and such Hedging Obligations. If the Borrower fails to make any such endorsement
or assignment to the Administrative Agent, the Administrative Agent or any of
its officers or employees are irrevocably authorized to make the same. The
Borrower agrees that until the Obligations (other than the contingent indemnity
obligations) and such Hedging Obligations have been paid in full (in cash) and
satisfied and all financing arrangements pursuant to any Loan Document and all
Designated Hedging Agreements have been terminated, the Borrower will not

                                      113
<PAGE>

assign or transfer to any Person (other than the Administrative Agent) any claim
the Borrower has or may have against any Guarantor.

              10.16 Lender's Not Utilizing Plan Assets. Each Lender represents
and warrants to the Borrower and the Administrative Agent that none of the
consideration used by such Lender to make or fund its Loans constitutes for any
purpose of ERISA or Section 4975 of the Code assets of any "plan" as defined in
Section 3(3) of ERISA or Section 4975 of the Code and the rights and interests
of such Lender in and under the Loan Documents shall not constitute such "plan
assets" under ERISA.

                   ARTICLE XI: THE ADMINISTRATIVE AGENT

              11.1 Appointment; Nature of Relationship. LaSalle is appointed by
the Holders of Secured Obligations as the Administrative Agent hereunder and
under each other Loan Document, and each of the Holders of Secured Obligations
irrevocably authorizes the Administrative Agent to act as the contractual
representative of such Holder of Secured Obligations with the rights and duties
expressly set forth herein and in the other Loan Documents. The Administrative
Agent agrees to act as such contractual representative upon the express
conditions contained in this Article XI. Notwithstanding the use of the defined
term "Administrative Agent," it is expressly understood and agreed that the
Administrative Agent shall not have any fiduciary responsibilities to any Holder
of Secured Obligations by reason of this Agreement and that the Administrative
Agent is merely acting as the representative of the Holders of Secured
Obligations with only those duties as are expressly set forth in this Agreement
and the other Loan Documents. In its capacity as the Holders of Secured
Obligations' contractual representative, the Administrative Agent (A) does not
assume any fiduciary duties to any of the Holders of Secured Obligations, (B) is
a "representative" of the Holders of Secured Obligations within the meaning of
Section 9-102 of the Uniform Commercial Code and (C) is acting as an independent
contractor, the rights and duties of which are limited to those expressly set
forth in this Agreement and the other Loan Documents. Each of the Holders of
Secured Obligations, for itself and on behalf of its affiliates as Holders of
Secured Obligations, agrees to assert no claim against the Administrative Agent
on any agency theory or any other theory of liability for breach of fiduciary
duty, all of which claims each Holder of Secured Obligations waives.

              11.2 Powers. The Administrative Agent shall have and may exercise
such powers under the Loan Documents as are specifically delegated to the
Administrative Agent by the terms of each thereof, together with such powers as
are reasonably incidental thereto. The Administrative Agent shall have no
implied duties or fiduciary duties or responsibilities to the Holders of Secured
Obligations, or any obligation to the Holders of Secured Obligations, to take
any action hereunder or under any of the other Loan Documents except any action
specifically provided by the Loan Documents required to be taken by the
Administrative Agent.

              11.3 General Immunity. Neither the Administrative Agent nor any of
its directors, officers, agents, employees or legal counsel shall be liable to
the Borrower, the Holders of Secured Obligations or any Holder of Secured
Obligations for any action taken or omitted to be taken by it or them hereunder
or under any other Loan Document or in connection herewith or therewith except
to the extent such action or inaction is found in a final judgment by a court of

                                      114
<PAGE>

competent jurisdiction to have arisen solely from the Gross Negligence or
willful misconduct of such Person.

              11.4 No Responsibility for Loans, Creditworthiness, Recitals, Etc.
Neither the Administrative Agent nor any of its directors, officers, agents,
employees or legal counsel shall be responsible for or have any duty to
ascertain, inquire into, or verify (A) any statement, warranty or representation
made in connection with any Loan Document or any borrowing hereunder; (B) the
performance or observance of any of the covenants or agreements of any obligor
under any Loan Document; (C) the satisfaction of any condition specified in
Article V, except receipt of items required to be delivered solely to the
Administrative Agent; (D) the existence or possible existence of any Default or
Unmatured Default or (E) the validity, effectiveness or genuineness of any Loan
Document or any other instrument or writing furnished in connection therewith.
The Administrative Agent shall not be responsible to any Holder of Secured
Obligations for any recitals, statements, representations or warranties herein
or any of the other Loan Documents, for the perfection or priority of the Liens
on any of the Collateral, or for the execution, effectiveness, genuineness,
validity, legality, enforceability, collectibility, or sufficiency of this
Agreement or any of the other Loan Documents or the transactions contemplated
thereby, or for the financial condition of any guarantor of any or all of the
Obligations, the Borrower or any of its Subsidiaries.

              11.5 Action on Instructions of Lenders; Actions with Respect to
Defaults. The Administrative Agent shall have the right to request instructions
from the Lenders at any time. If the Administrative Agent shall request
instructions from the Lenders with respect to any act or action (including the
failure to act) in connection with this Agreement or any other Loan Document,
the Administrative Agent shall be entitled to refrain from such act or taking
such action unless and until the Administrative Agent shall have received
instructions signed by the Required Lenders (or all of the Lenders in the event
that and to the extent that this Agreement or any other Loan Document expressly
requires such), and the Administrative Agent shall not incur liability to any
Person by reason of so refraining, and such instructions and any action taken or
failure to act pursuant thereto shall be binding on all of the Holders of
Secured Obligations and on all owners of Loans and on all Holders of Secured
Obligations. Without limiting the foregoing, no Holder of Secured Obligation
shall have any right of action whatsoever against the Administrative Agent as a
result of the Administrative Agent acting or refraining from acting hereunder in
accordance with the instructions of all of the Lenders. The Administrative Agent
shall be fully justified in failing or refusing to take any action hereunder and
under any other Loan Document unless it shall first be indemnified to its
satisfaction by the Lenders pro rata against any and all liability, cost and
expense that it may incur by reason of taking or continuing to take any such
action. In addition to the Administrative Agent's right to take actions on its
own accord as permitted under this Agreement, the Administrative Agent shall
take such action with respect to an Unmatured Default or Default as shall be
directed by the Required Lenders; provided, that until the Administrative Agent
shall have received such directions, the Administrative Agent may (but shall not
be obligated to) take such action, or refrain from taking such action, with
respect to such Unmatured Default or Default as it shall deem advisable and in
the best interests of the Holders of Secured Obligations.

              11.6 Employment of Agents and Counsel. The Administrative Agent
may execute any of its duties as the Administrative Agent hereunder and under
any other Loan

                                      115
<PAGE>

Document by or through employees, agents, and attorneys-in-fact and shall not be
liable to the Holders of Secured Obligations, except as to money or securities
received by it or its authorized agents, for the default or misconduct of any
such agents or attorneys-in-fact selected by it with reasonable care. The
Administrative Agent shall be entitled to advice of counsel concerning the
contractual arrangement between the Administrative Agent and the Holders of
Secured Obligations and all matters pertaining to the Administrative Agent's
duties hereunder and under any other Loan Document.

              11.7 Reliance on Documents; Counsel. The Administrative Agent
shall be entitled to rely upon any notice, consent, certificate, affidavit,
letter, telegram, statement, paper or document believed by it to be genuine and
correct and to have been signed or sent by the proper person or persons, and, in
respect to legal matters, upon the opinion of counsel selected by the
Administrative Agent, which counsel may be employees of the Administrative
Agent.

              11.8 The Administrative Agent's Reimbursement and Indemnification.
The Holders of Secured Obligations agree to reimburse and indemnify the
Administrative Agent ratably in proportion to its Pro Rata Share (A) for any
amounts not reimbursed by the Borrower for which the Administrative Agent is
entitled to reimbursement by the Borrower under the Loan Documents, (B) for any
other expenses incurred by the Administrative Agent on behalf of the Holders of
Secured Obligations, in connection with the enforcement of the Loan Documents
and (C) for any liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind and nature
whatsoever which may be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of the Loan Documents
or any other document delivered in connection therewith or the transactions
contemplated thereby, or the enforcement of any of the terms thereof or of any
such other documents, provided that no Holder of Secured Obligations shall be
liable for any of the foregoing to the extent any of the foregoing is found in a
final non-appealable judgment by a court of competent jurisdiction to have
arisen solely from the Gross Negligence or willful misconduct of the
Administrative Agent.

              11.9 Rights as a Lender. With respect to its Revolving Loan
Commitment, its Term Loan Commitment, Loans made by it, and Letters of Credit
issued by it, the Administrative Agent shall have the same rights and powers
hereunder and under any other Loan Document as any Lender or Issuing Bank and
may exercise the same as though it were not the Administrative Agent, and the
term "Lender" or "Lenders", "Issuing Bank" or "Issuing Banks" shall, unless the
context otherwise indicates, include the Administrative Agent in its individual
capacity. The Administrative Agent may accept deposits from, lend money to, and
generally engage in any kind of trust, debt, equity or other transaction, in
addition to those contemplated by this Agreement or any other Loan Document,
with the Borrower or any of its Subsidiaries in which such Person is not
prohibited hereby from engaging with any other Person.

              11.10 Lender Credit Decision. Each Holder of Secured Obligations
acknowledges that it has, independently and without reliance upon the
Administrative Agent, the Arranger or any other Holder of Secured Obligations
and based on the financial statements prepared by the Borrower and such other
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement and the other Loan Documents.
Each Holder of Secured Obligations also acknowledges that it will,

                                      116
<PAGE>

independently and without reliance upon the Administrative Agent, the Arranger
or any other Holder of Secured Obligations and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit decisions in taking or not taking action under this Agreement and the
other Loan Documents.

              11.11 Successor Administrative Agent. The Administrative Agent may
resign at any time by giving written notice thereof to the Lenders and the
Borrower. Upon any such resignation, the Required Lenders shall have the right
(with, so long as no Default is continuing, the Borrower's consent (which
consent shall not be unreasonably withheld or delayed)) to appoint, on behalf of
the Borrower and the Holders of Secured Obligations, a successor Administrative
Agent. If no successor Administrative Agent shall have been so appointed by the
Required Lenders and shall have accepted such appointment within thirty days
after the retiring Administrative Agent's giving notice of resignation, then the
retiring Administrative Agent may appoint (with, so long as no Default or
Unmatured Default is continuing, the Borrower's consent), on behalf of the
Borrower and the Holders of Secured Obligations, a successor Administrative
Agent. Notwithstanding anything herein to the contrary, so long as no Default
has occurred and is continuing, each such successor Administrative Agent shall
be subject to approval by the Borrower, which approval shall not be unreasonably
withheld or delayed. Such successor Administrative Agent shall be a commercial
bank or other financial institution having capital and retained earnings of at
least $500,000,000. Upon the acceptance of any appointment as the Administrative
Agent hereunder by a successor Administrative Agent, such successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Administrative Agent, and
the retiring Administrative Agent shall be discharged from its duties and
obligations hereunder and under the other Loan Documents. After any retiring
Administrative Agent's resignation hereunder as Administrative Agent, the
provisions of this Article XI shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as
the Administrative Agent hereunder and under the other Loan Documents.

              11.12 Collateral Documents; Subordination Agreements; Collateral.


              (A) Authority to Take Action. Each Holder of Secured Obligations
        authorizes the Administrative Agent to enter into each of the Collateral
        Documents and the subordination agreements in respect of the
        Subordinated Notes to which it is a party and to take all action
        contemplated by such documents. Each Holder of Secured Obligations
        agrees that no Holder of Secured Obligations (other than the
        Administrative Agent) shall have the right individually to seek to
        realize upon the security granted by any Collateral Document, it being
        understood and agreed that such rights and remedies may be exercised
        solely by the Administrative Agent for the benefit of the Holders of
        Secured Obligations upon the terms of the Collateral Documents.

              (B) Authority to Execute and Deliver. In the event that any
        Collateral is hereafter pledged by any Person as collateral security for
        the Obligations, the Administrative Agent is hereby authorized to
        execute and deliver on behalf of the Holders of Secured Obligations any
        Loan Documents necessary or appropriate to grant and perfect a Lien on
        such Collateral in favor of the Administrative Agent on behalf of the
        Holders of Secured Obligations.

                                      117
<PAGE>

              (C) Authority to Release Liens. The Holders of Secured Obligations
        hereby authorize the Administrative Agent, at its option and in its
        discretion, to release any Lien granted to or held by the Administrative
        Agent upon any Collateral (i) upon termination of the Commitments and
        payment in cash and satisfaction of all of the Obligations at any time
        arising under or in respect of this Agreement or the Loan Documents or
        the transactions contemplated hereby or thereby; (ii) as permitted by,
        but only in accordance with, the terms of the applicable Loan Document;
        or (iii) if approved, authorized or ratified in writing by the Required
        Lenders, unless such release is required to be approved by all of the
        Lenders hereunder. Upon request by the Administrative Agent at any time,
        the Lenders will confirm in writing the Administrative Agent's authority
        to release particular types or items of Collateral pursuant to this
        Section 11.12(C).

              (D) Additional Authority. Upon any sale or transfer of assets
        constituting Collateral which is expressly permitted pursuant to the
        terms of any Loan Document, or consented to in writing by the Required
        Lenders or all of the Lenders, as applicable, and upon at least five (5)
        Business Days' prior written request by the Borrower, the Administrative
        Agent shall (and is hereby irrevocably authorized by the Holders of
        Secured Obligations to) execute such documents as may be necessary to
        evidence the release of the Liens granted to the Administrative Agent
        for the benefit of the Holders of Secured Obligations herein or pursuant
        hereto upon the Collateral that was sold or transferred; provided,
        however, that (i) the Administrative Agent shall not be required to
        execute any such document on terms which, in the Administrative Agent's
        opinion, would expose the Administrative Agent to liability or create
        any obligation or entail any consequence other than the release of such
        Liens without recourse or warranty, and (ii) such release shall not in
        any manner discharge, affect or impair the Secured Obligations or any
        Liens upon (or obligations of the Borrower or any Subsidiary in respect
        of) all interests retained by the Borrower or any Subsidiary, including
        (without limitation) the proceeds of the sale, all of which shall
        continue to constitute part of the Collateral.

              (E) No Obligation to Monitor Collateral. The Administrative Agent
        shall have no obligation whatsoever to the Holders of Secured
        Obligations or to any other Person to assure that the Collateral exists
        or is owned by the Borrower or any of its Subsidiaries or is cared for,
        protected or insured or that the Liens granted to the Administrative
        Agent under the Loan Documents have been properly or sufficiently or
        lawfully created, perfected, protected or enforced or are entitled to
        any particular priority, or to exercise or to continue exercising at all
        or in any manner or under any duty of care, disclosure or fidelity any
        of the rights, authorities and powers granted or available to the
        Administrative Agent in this Article XI or in any of the Loan Documents,
        it being understood and agreed that in respect of the Collateral, or any
        act, omission or event related thereto, the Administrative Agent may act
        in any manner it may deem appropriate, in its sole discretion, given the
        Administrative Agent's own interest in the Collateral as one of the
        Holders of Secured Obligations and that the Administrative Agent shall
        have no duty or liability whatsoever to the Holders of Secured
        Obligations, except for its Gross Negligence or willful misconduct.

              11.13 Arranger. The Arranger shall have no right, power,
obligation, liability, responsibility or duty under this Agreement other than
those applicable to all Lenders as such.


                                      118
<PAGE>

Without limiting the foregoing, the Arranger shall not have or be deemed to have
a fiduciary relationship with any Holder of Secured Obligations. Each Holder of
Secured Obligations hereby makes the same acknowledgements with respect to the
Arranger as it makes with respect to the Administrative Agent in Section 11.10.

                   ARTICLE XII: SETOFF; RATABLE PAYMENTS

              12.1 Setoff. In addition to, and without limitation of, any rights
of the Lenders under applicable law, if any Default occurs and is continuing,
any Indebtedness from any Lender to the Borrower (including all account
balances, whether provisional or final and whether or not collected or
available) may be offset and applied toward the payment of the Obligations owing
to such Lender, whether or not the Obligations, or any part hereof, shall then
be due. Such Lender shall give prompt notice to the Borrower and the
Administrative Agent of any such offset.

              12.2 Ratable Payments. If any Lender, whether by setoff or
otherwise, has payment made to it upon its Loans (other than payments received
pursuant to Sections 4.1, 4.2 or 4.4) in a greater proportion than that received
by any other Lender, such Lender agrees, promptly upon demand, to purchase a
portion of the Loans held by the other Lenders so that after such purchase each
Lender will hold its ratable proportion of Loans. If any Lender, whether in
connection with setoff or amounts which might be subject to setoff or otherwise,
receives collateral or other protection for its Obligation or such amounts which
may be subject to setoff, such Lender agrees, promptly upon demand, to take such
action necessary such that all Lenders share in the benefits of such collateral
ratably in proportion to the obligations owing to them. In case any such payment
is disturbed by legal process, or otherwise, appropriate further adjustments
shall be made.

              12.3 Application of Payments. The Administrative Agent shall,
unless otherwise specified at the direction of the Required Lenders which
direction shall be consistent with the last two sentences of this Section 12.3,
apply all payments and prepayments in respect of any Obligations and all
proceeds of the Collateral in the following order:

              (i) first, to pay interest on and then principal of any portion of
        the Loans which the Administrative Agent may have advanced on behalf of
        any Lender for which the Administrative Agent has not then been
        reimbursed by such Lender or the Borrower;

              (ii) second, to pay interest on and then principal of any advance
        made under Section 10.3 for which the Administrative Agent has not then
        been paid by the Borrower or reimbursed by the Lenders;

              (iii) third, to the ratable payment of the Obligations in respect
        of any fees, expenses, reimbursements or indemnities then due to the
        Administrative Agent;

              (iv) fourth, to pay Obligations in respect of any fees, expenses,
        reimbursements or indemnities then due to the Lenders and the issuer(s)
        of Letters of Credit;

              (v) fifth, to pay interest due in respect of Swing Line Loans;


                                      119
<PAGE>

              (vi) sixth, to pay interest due in respect of Loans.

              (vii) seventh, to the ratable payment or prepayment of principal
        outstanding on Swing Line Loans;

              (viii) eighth, to the ratable payment or prepayment of principal
        outstanding on the Term Loans;

              (ix) ninth, to the ratable payment or prepayment of principal
        outstanding on Loans (other than Swing Line Loans and Term Loans) and
        Reimbursement Obligations in such order as the Administrative Agent may
        determine;

              (x) tenth, to the ratable payment or prepayment of Hedging
        Obligations under Hedging Agreements in such order as the Administrative
        Agent may determine in its sole discretion;

              (xi) eleventh, to provide required cash collateral, if required
        pursuant to Section 3.11 and

              (xii) twelfth, to the ratable payment of all other Obligations.

Unless otherwise required by the terms of this Agreement, all principal payments
in respect of Loans (other than Swing Line Loans) shall be applied first, to
repay outstanding Floating Rate Loans, and then to repay outstanding Eurodollar
Rate Loans with those Eurodollar Rate Loans which have earlier expiring Interest
Periods being repaid prior to those which have later expiring Interest Periods.
The order of priority set forth in this Section 12.3 and the related provisions
of this Agreement are set forth solely to determine the rights and priorities of
the Administrative Agent, the Lenders, the Swing Line Bank and the issuer(s) of
Letters of Credit as among themselves. The order of priority set forth in
clauses (iv) through (x) of this Section 12.3 may at any time and from time to
time be changed at the direction of the Lenders without necessity of notice to
or consent of or approval by the Borrower, or any other Person; provided, that
the order of priority of payments in respect of Swing Line Loans may be changed
only with the prior written consent of the Swing Line Bank. The order of
priority set forth in clauses (i) through (iii) of this Section 12.3 may be
changed only with the prior written consent of the Administrative Agent, and, in
the case of clause (iii), with the prior written consent of the Arranger.

              12.4 Relations Among Lenders.


              (A) No Action Without Consent. Except with respect to the exercise
        of set-off rights of any Lender in accordance with Section 12.1, the
        proceeds of which are applied in accordance with this Agreement, each
        Lender agrees that it will not take any action, nor institute any
        actions or proceedings, against the Borrower or any other obligor
        hereunder or with respect to any Loan Document, without the prior
        written consent of the Required Lenders or, as may be provided in this
        Agreement or the other Loan Documents, with the consent of the
        Administrative Agent.

              (B) Not Partners; No Liability. The Lenders are not partners or
        co-venturers, and no Lender shall be liable for the acts or omissions
        of, or (except as otherwise set forth

                                      120
<PAGE>

        herein in case of the Administrative Agent) authorized to act for, any
        other Lender. The Administrative Agent shall have the exclusive right on
        behalf of the Lenders to enforce the payment of the principal of and
        interest on any Loan after the date such principal or interest has
        become due and payable pursuant to the terms of this Agreement.

      ARTICLE XIII: BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

              13.1 Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns, except that (A) the
Borrower shall not have the right to assign its rights or obligations under the
Loan Documents without the consent of all of the Lenders, and any such
assignment in violation of this Section 13.1(A) shall be null and void, and (B)
any assignment by any Lender must be made in compliance with Section 13.3
hereof. Notwithstanding clause (B) of this Section 13.1 or Section 13.3, (i) any
Lender may at any time, without the consent of the Borrower or the
Administrative Agent, assign all or any portion of its rights under this
Agreement to a Federal Reserve Bank and (ii) any Lender which is a fund or
commingled investment vehicle that invests in commercial loans in the ordinary
course of its business may at any time, without the consent of the Borrower or
the Administrative Agent, pledge or assign all or any part of its rights under
this Agreement to a trustee or other representative of holders of obligations
owed or securities issued by such Lender as collateral to secure such
obligations or securities; provided, however, that no such assignment or pledge
shall release the transferor Lender from its obligations hereunder, unless and
until the parties thereto have complied with the provisions of Section 13.3. The
Administrative Agent may treat each Lender as the owner of the Loans made by
such Lender hereunder for all purposes hereof unless and until such Lender
complies with Section 13.3 hereof in the case of an assignment thereof or, in
the case of any other transfer, a written notice of the transfer is filed with
the Administrative Agent. Any assignee or transferee of a Loan, Commitment, L/C
Interest or any other interest of a Lender under the Loan Documents agrees by
acceptance thereof to be bound by all the terms and provisions of the Loan
Documents. Any request, authority or consent of any Person, who at the time of
making such request or giving such authority or consent is the owner of any
Loan, shall be conclusive and binding on any subsequent owner, transferee or
assignee of such Loan.

              13.2 Participations.


              (A) Permitted Participants; Effect. Subject to the terms set forth
in this Section 13.2, any Lender may, in the ordinary course of its business and
in accordance with applicable law, at any time sell to one or more banks or
other entities that are U.S. Qualified Persons ("PARTICIPANTS") participating
interests in any Loan owing to such Lender, any Revolving Loan Commitment of
such Lender, any L/C Interest of such Lender or any other interest of such
Lender under the Loan Documents on a pro rata or non-pro rata basis. Notice of
such participation to the Borrower and the Administrative Agent shall be
required prior to any participation becoming effective with respect to a
Participant which is not a Lender or an Affiliate thereof. Upon receiving said
notice, the Administrative Agent shall record the participation in the Register
it maintains. Moreover, notwithstanding such recordation, such participation
shall not be considered an assignment under Section 13.3 of this Agreement and
such Participant shall not be considered a Lender. In the event of any such sale
by a Lender of participating interests

                                      121
<PAGE>

to a Participant, such Lender's obligations under the Loan Documents shall
remain unchanged, such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, such Lender shall remain
the owner of all Loans made by it for all purposes under the Loan Documents, all
amounts payable by the Borrower under this Agreement shall be determined as if
such Lender had not sold such participating interests, and the Borrower and the
Administrative Agent shall continue to deal solely and directly with such Lender
in connection with such Lender's rights and obligations under the Loan Documents
except that, for purposes of Article IV hereof, the Participants shall be
entitled to the same rights as if they were Lenders.

              (B) Voting Rights. Each Lender shall retain the sole right to
approve, without the consent of any  Participant, any amendment,
modification or waiver of any provision of the Loan Documents other than any
amendment, modification or waiver with respect to any Loan, Letter of Credit or
Revolving Loan Commitment in which such Participant has an interest which
forgives principal, interest or Letter of Credit or commitment fees or reduces
the interest rate or Letter of Credit or commitment fees payable pursuant to the
terms of this Agreement with respect to any such Loan or Revolving Loan
Commitment, or postpones any date fixed for any regularly-scheduled payment (but
not any prepayment) of principal of, or interest or Letter of Credit or
commitment fees on, any such Loan or Revolving Loan Commitment, or releases all
or substantially all of the Collateral, if any, securing any such Loan or Letter
of Credit.

              (C) Benefit of Setoff. The Borrower agrees that each Participant
shall be deemed to have the right of setoff provided in Section 12.1 hereof in
respect to its participating interest in amounts owing under the Loan Documents
to the same extent as if the amount of its participating interest were owing
directly to it as a Lender under the Loan Documents, provided that each Lender
shall retain the right of setoff provided in Section 12.1 hereof with respect to
the amount of participating interests sold to each Participant except to the
extent such Participant exercises its right of setoff. The Lenders agree to
share with each Participant, and each Participant, by exercising the right of
setoff provided in Section 12.1 hereof, agrees to share with each Lender, any
amount received pursuant to the exercise of its right of setoff, such amounts to
be shared in accordance with Section 12.2 as if each Participant were a Lender.

              13.3 Assignments.


              (A) Permitted Assignments.


              (i) Any Lender (each such assigning Lender under this Section 13.3
           being a "SELLER") may, in accordance with applicable law, at any time
           assign to one or more banks or other entities (other than the
           Borrower or any of its Affiliates) that are U.S. Qualified Persons
           ("PURCHASERS") all or a portion of its rights and obligations under
           this Agreement and the other Loan Documents (including, without
           limitation, its Revolving Loan Commitment, all Loans owing to it, all
           of its participation interests in existing Letters of Credit and
           Swing Line Loans, and its obligation to participate in additional
           Letters of Credit and Swing Line Loans hereunder) in accordance with
           the provisions of this Section 13.3. Each assignment shall be of a
           constant, and not a


                                      122
<PAGE>

           varying, ratable percentage of all of the Seller's rights and
           obligations under this Agreement. Such assignment shall be
           substantially in the form of Exhibit D hereto and shall not be
           permitted hereunder unless such assignment is either for all of such
           Seller's rights and obligations under the Loan Documents or, without
           the prior written consent of the Administrative Agent, involves loans
           and commitments in an aggregate amount of at least $5,000,000 (or, if
           less, all of such Lender's rights and obligations under the Loan
           Documents, and which minimum amount shall not apply to any assignment
           between Lenders. The written consent of the Administrative Agent,
           and, prior to the occurrence of a Default, and only with respect to
           any assignment other than to another Lender, the Borrower (which
           consent, in each such case, shall not be unreasonably withheld or
           delayed), shall be required prior to an assignment becoming effective
           with respect to a Purchaser which is not a Lender, an Affiliate of
           such assigning Lender or Approved Fund of such assigning Lender;
           provided, no consent of the Borrower shall be required in connection
           with any assignment by any Lender consummated after consultation with
           the Borrower during the Syndication Period.

              (ii) Notwithstanding anything to the contrary contained herein,
           any Lender (each such Lender, a "GRANTING Bank") may grant to a
           special purpose funding vehicle (each such special purpose funding
           vehicle, a "SPC"), identified as such in writing from time to time by
           the applicable Granting Bank to the Administrative Agent and the
           Borrower, the option to provide to the Borrower all or any part of
           any Advance that such Granting Bank would otherwise be obligated to
           make to the Borrower pursuant to this Agreement; provided, that (i)
           nothing herein shall constitute a commitment by any SPC to make any
           Advance, (ii) if an SPC elects not to exercise such option or
           otherwise fails to provide all or any part of such Advance, the
           applicable Granting Bank shall be obligated to make such Advance
           pursuant to the terms hereof. The making of an Advance by any SPC
           hereunder shall utilize the Revolving Loan Commitment of the
           applicable Granting Bank to the same extent, and as if, such Advance
           were made by such Granting Bank. Each party hereto hereby agrees that
           no SPC shall be liable for any indemnity or other similar payment
           obligation under this Agreement (all liability for which shall remain
           with the applicable Granting Bank). All notices hereunder to any
           Granting Bank or the related SPC, and all payments in respect of the
           Obligations due to such Granting Bank or the related SPC, shall be
           made to such Granting Bank. In addition, each Granting Bank shall
           vote as a Lender hereunder without giving effect to any assignment
           under this Section 13.3(A)(ii), and no SPC shall have any vote as a
           Lender under this Agreement for any purpose. In furtherance of the
           foregoing, each party hereto hereby agrees (which agreement shall
           survive the termination of this Agreement) that, prior to the date
           that is one year and one day after the payment in full of all
           outstanding commercial paper or other senior indebtedness of any SPC,
           it will not institute against, or join any other person in
           instituting against, such SPC any bankruptcy, reorganization,
           arrangement, insolvency or liquidation proceedings under the laws of
           the United States or any State thereof in relation to matters arising
           under this Agreement. In addition, notwithstanding anything to the
           contrary contained in this Section 13.3, any SPC may (i) with notice
           to, but without the prior written consent of, the Borrower and the
           Administrative Agent and without paying any processing or

                                      123
<PAGE>

           administrative fee therefor, assign all or a portion of its interests
           in any Advances to the Granting Bank or to any financial institutions
           (consented to by the Borrower and the Administrative Agent in
           accordance with the terms of Section 13.3(A)(i)) providing liquidity
           and/or credit support to or for the account of such SPC to support
           the funding or maintenance of Advances and (ii) disclose on a
           confidential basis any non-public information relating to its
           Advances to any rating agency, commercial paper dealer or provider of
           any surety, guarantee or credit or liquidity enhancement to such SPC.
           This Section 13.3(A)(ii) may not be amended without the written
           consent of each SPC affected thereby.

              (B) Effect; Effective Date. Upon (i) delivery to the
        Administrative Agent of a notice of assignment, substantially in the
        form attached as Appendix I to Exhibit D hereto (a "NOTICE OF
        ASSIGNMENT"), together with any consent required by Section 13.3(A)
        hereof, (ii) payment of a $3,500 fee by the assignor to the
        Administrative Agent for processing such assignment, and (iii) the
        completion of the recording requirements in Section 13.3(C), such
        assignment shall become effective on the later of such date when the
        requirements in clauses (i), (ii), and (iii) are met or the effective
        date specified in such Notice of Assignment. The Notice of Assignment
        shall contain a representation by the Purchaser to the effect that none
        of the consideration used to make the purchase of the Commitment, Loans
        and L/C Obligations under the applicable assignment agreement are "plan
        assets" as defined under ERISA and that the rights and interests of the
        Purchaser in and under the Loan Documents will not be "plan assets"
        under ERISA. On and after the effective date of such assignment, such
        Purchaser, if not already a Lender, shall for all purposes be a Lender
        party to this Agreement and any other Loan Documents executed by the
        Lenders and shall have all the rights and obligations of a Lender under
        the Loan Documents, to the same extent as if it were an original party
        hereto, and no further consent or action by the Borrower, the Lenders or
        the Administrative Agent shall be required to release the Seller with
        respect to the percentage of the Aggregate Revolving Loan Commitment,
        Loans and Letter of Credit and Swing Line Loan participations assigned
        to such Purchaser. Upon the consummation of any assignment to a
        Purchaser pursuant to this Section 13.3(B), the Seller, the
        Administrative Agent and the Borrower shall make appropriate
        arrangements so that, to the extent notes have been issued to evidence
        any of the transferred Loans, replacement notes are issued to such
        Seller and new notes or, as appropriate, replacement notes, are issued
        to such Purchaser, in each case in principal amounts reflecting their
        Revolving Loan Commitment and their Term Loans, as adjusted pursuant to
        such assignment. Notwithstanding anything to the contrary herein, the
        Borrower shall not, at any time, be obligated to pay under Section
        2.15(E) to any Lender that is a Purchaser, assignee or transferee any
        sum in excess of the sum which the Borrower would have been obligated to
        pay in respect of such transferred Loan to the Lender that was the
        Seller, assignor or transferor had such assignment or transfer not been
        effected.


              (C) The Register. Notwithstanding anything to the contrary in this
        Agreement, the Borrower hereby designates the Administrative Agent, and
        the Administrative Agent, hereby accepts such designation, to serve as
        the Borrower's contractual representative solely for purposes of this
        Section 13.3(C). In this connection, the Administrative Agent shall
        maintain at its address referred to in Section 14.1 a copy

                                      124
<PAGE>

        of each assignment delivered to and accepted by it pursuant to this
        Section 13.3 and a register (the "REGISTER") for the recordation of the
        names and addresses of the Lenders and the Revolving Loan Commitment of,
        principal amount of and interest on the Loans owing to, each Lender from
        time to time and whether such Lender is an original Lender or the
        assignee of another Lender pursuant to an assignment under this Section
        13.3. The entries in the Register shall be conclusive and binding for
        all purposes, absent manifest error, and the Borrower and each of its
        Subsidiaries, the Administrative Agent and the Lenders may treat each
        Person whose name is recorded in the Register as a Lender hereunder for
        all purposes of this Agreement. The Register shall be available for
        inspection by the Borrower or any Lender at any reasonable time and from
        time to time upon reasonable prior notice.

              13.4 Confidentiality. Subject to Section 13.5, the Administrative
Agent and the Lenders and their respective representatives, consultants and
advisors shall hold all nonpublic information obtained pursuant to the
requirements of this Agreement and identified as such by the Borrower in
accordance with such Person's customary procedures for handling confidential
information of this nature and in accordance with safe and sound commercial
lending or investment practices and in any event may make disclosure reasonably
required by a prospective Transferee in connection with the contemplated
participation or assignment or as required or requested by any Governmental
Authority or any securities exchange or similar self-regulatory organization or
representative thereof or pursuant to a regulatory examination or legal process,
or to any direct or indirect contractual counterparty in swap agreements or such
contractual counterparty's professional advisor, and shall require any such
Transferee to agree (and require any of its Transferees to agree) to comply with
this Section 13.4. In no event shall the Administrative Agent or any Lender be
obligated or required to return any materials furnished by the Borrower;
provided, however, each prospective Transferee shall be required to agree that
if it does not become a participant or assignee it shall return all materials
furnished to it by or on behalf of the Borrower in connection with this
Agreement.

              13.5 Dissemination of Information. The Borrower authorizes each
Lender to disclose to any Participant or Purchaser or any other Person acquiring
an interest in the Loan Documents by operation of law (each a "Transferee") and
any prospective Transferee any and all information in such Lender's possession
concerning the Borrower and its Subsidiaries; provided that prior to any such
disclosure, such prospective Transferee shall agree to preserve in accordance
with Section 13.4 the confidentiality of any confidential information described
therein.

                              ARTICLE XIV: NOTICES

              14.1 Giving Notice. Except as otherwise permitted by Section 2.14

provided to any party hereto under this Agreement or any other Loan Documents
shall be in writing or by facsimile and addressed or delivered to such party at
its address set forth below its signature hereto or at such other address as may
be designated by such party in a notice to the other parties. For all purposes

              14.2 Change of Address. The Borrower, the Administrative Agent and
any Lender may each change the address for service of notice upon it by a notice
in writing to the other parties hereto.

                            ARTICLE XV: COUNTERPARTS

              This Agreement may be executed in any number of counterparts, all
of which taken together shall constitute one agreement, and any of the parties
hereto may execute this Agreement by signing any such counterpart. This
Agreement shall be effective when it has been executed by the Borrower, the
Administrative Agent and the Lenders and each party has notified the
Administrative Agent by telephone, that it has taken such action.
