principal amount of the Term Note; (b) mark the Prior Note as replaced by the

Date), Lender may, in addition to any of its other rights and remedies

                               Page 29 of 82 Pages


under this Agreement and the other Loan Documents, liquidate the Cash Collateral
and Collateral and apply the proceeds thereof to pay all amounts owing to
Lender.

     (b)    OPTIONAL PREPAYMENTS. Borrower may from time to time prepay any
Loan, or portion thereof, bearing interest at the Prime Rate at any time and may
prepay any Loan, or portion thereof, bearing interest at LIBOR at the end of the
maturity period chosen or deemed elected by Borrower applicable to the advance
or portion of the advance being prepaid, without premium or penalty; PROVIDED,
that any partial prepayment shall be in an aggregate principal amount of at
least $10,000. Any prepayment of a Loan, or portion thereof, bearing interest at
LIBOR at a date other than the maturity date applicable to the advance or the
portion of the advance being prepaid shall be subject to the provisions of
SECTION 2.5(e) herein. All prepayments of principal shall include interest
accrued to the date of prepayment on the principal amount being prepaid, and, in
the case of the Term Loan, shall be applied to the unpaid installments, if any,
of the Term Loan in the inverse order of maturity.

     (c)    MANDATORY PREPAYMENTS. In the event that (i) the aggregate principal
amount of outstanding Revolving Loans PLUS the aggregate Stated Amount of all
Revolving Letters of Credit exceeds the Revolving Commitment, including after
giving effect to any reduction or termination in the amount of the Revolving
Commitment permitted or required by SECTION 2.6 or SECTION 2.7 or occurring as a
result of SECTION 8.2, then Borrower immediately shall make a payment of
principal on the Revolving Loans in an amount sufficient to eliminate such
excess, PROVIDED, that if such excess is not eliminated after the payment of the
principal of all outstanding Revolving Loans then Borrower shall Cash
Collateralize the Revolving Letters of Credit in the amount of such excess;
PROVIDED, FURTHER, that upon the occurrence and during the continuation of any
Default or Event of Default, Lender may liquidate such Cash Collateral and apply
the proceeds thereof to pay all amounts owing to Lender; (ii) all outstanding
Obligations exceed the Collateral Base, Borrower shall immediately comply with
the provisions of SECTION 6.11 herein to reduce such excess; or (iii) Borrower
sells any of its assets outside the ordinary course of Borrower's business (and
in accordance with SECTION 7.1 herein), Borrower shall immediately apply the
proceeds received from the sale of such assets, less reasonable costs of
disposition, to repay the outstanding Obligations under the Term Facility
(including, if necessary, Cash Collateralizing the L/C Obligations pertaining to
the Term Letters of Credit), unless otherwise agreed in writing by Lender.
Lender shall have the right, in its sole discretion, to apply mandatory payments
received by it, in any order and against any Obligations outstanding.

     2.5.   INTEREST .

     (a)    RATES. The unpaid principal amount of each Loan from time to time
outstanding hereunder shall bear interest at the following rates per year:

            (i)     before maturity of any Loan, whether by acceleration or
     otherwise, at the option of Borrower subject to the terms hereof at a rate
     equal to:

                    (A) "LIBOR," which shall mean that fixed rate of interest
            per year for deposits with maturity periods of 1, 3 or 6 months
            (which maturity period Borrower shall select subject to the terms
            stated herein) in United States dollars offered to Lender in or
            through the London interbank market at or about 11:00 A.M., London
            time, three Business Days before the rate is to take effect in an
            amount corresponding to the amount of such Loan, or portion thereof)
            and for the London deposit maturity requested, DIVIDED BY one minus
            any applicable reserve requirement (expressed as a decimal) on
            Eurodollar deposit of the same amount and maturity as determined by
            Lender in its sole discretion, PLUS 325 basis points; or

                    (B) the Prime Rate; and

                               Page 30 of 82 Pages


            (ii)    after the maturity of any Loan, until paid, at a rate equal
     to 2% in addition to the Prime Rate (but not less than the Prime Rate in
     effect at maturity).

     (b)    RATE SELECTION. Borrower shall select and change its selection of
the interest rate as between LIBOR and the Prime Rate to apply to any Loan, or
portion thereof, to at least $100,000 and in integral multiples of $100,000
thereafter of any advance, subject to the requirements herein stated:

            (i)     At the time a Loan is made;

            (ii)    At the expiration of the particular LIBOR maturity period
     selected for the outstanding principal balance of any Loan currently
     bearing interest at LIBOR; and

            (iii)   At any time for the outstanding principal balance of any
     Loan currently bearing interest at the Prime Rate.

     (c)    RATE CHANGES AND NOTIFICATIONS.

            (i)     LIBOR. If Borrower wishes to borrow funds at LIBOR or if
     Borrower wishes to change the rate of interest on any Loan, or portion
     thereof, within the limits described above, from any other rate to LIBOR,
     it shall, not less than three Business Days prior to the Business Day on
     which such rate is to take effect, give Lender written or telephonic notice
     thereof, which shall be irrevocable; PROVIDED, that the rate of interest on
     such Loan or any portion thereof bearing interest at LIBOR may be changed
     only on the last day of the maturity period thereof. Such notice shall
     specify the Loan, or portion thereof, to which LIBOR is to apply, and, in
     addition, the desired LIBOR maturity period of one, three or six months
     (but not to exceed the Termination Date).

            (ii)    PRIME RATE. If Borrower wishes to borrow all or any portion
     of a Loan at the Prime Rate or to change the rate of interest on such Loan,
     or any portion thereof, to the Prime Rate, it shall, at or before 12:00
     noon, Chicago time on the date such borrowing or change is to take effect,
     which shall be a Business Day, give written or telephonic notice thereof,
     which shall be irrevocable; PROVIDED, that the rate of interest on such
     Loan or any portion thereof bearing interest at LIBOR may be changed only
     on the last day of any maturity period thereof. Such notice shall specify
     the amount of such Loan, or any portion thereof, to which the Prime Rate is
     to apply.

            (iii)   FAILURE TO NOTIFY. If Borrower does not notify Lender at the
     expiration of a selected maturity period with respect to any Loan, or
     portion thereof, outstanding at LIBOR, then in the absence of such notice,
     Borrower shall be deemed to have elected to have such Loan, or portion
     thereof, accrue interest after the respective LIBOR maturity period at the
     Prime Rate.

     (d)    INTEREST PAYMENT DATES. Accrued interest shall be paid in respect of
each portion of principal of any Loan to which the Prime Rate applies in arrears
on the last day of each calendar quarter of each year, at maturity, and upon
payment in full, and to each portion of principal of any Loan to which LIBOR
applies, the earlier or more frequent of the end of each respective maturity
period for such portion or every three months, at maturity, and upon payment in
full. If any such payment of interest at LIBOR falls due on a day that is not a
Business Day, payment shall be made on the next Business Day; however, if such
day would be in the following month, such interest shall be paid on the last
Business Day in the month when the interest payment is due. After maturity of
any installment of any Loan, interest shall be payable upon demand.

                               Page 31 of 82 Pages


     (e)    ADDITIONAL PROVISIONS WITH RESPECT TO LIBOR. The selection by
Borrower of LIBOR and the maintenance of Loans, or any portion thereof, at such
rate shall be subject to the following additional terms and conditions:

            (i)     AVAILABILITY OF DEPOSITS AT A DETERMINABLE RATE. If, after
     Borrower has elected to borrow or maintain any Loan, or portion thereof, at
     LIBOR, Lender notifies Borrower that:

                    (A) United States dollar deposits in the amount and for the
            maturity requested are not available to Lender in the London
            interbank market, or

                    (B) Reasonable means do not exist for Lender to determine
            LIBOR for the amount and maturity requested,

     all as determined by Lender in its sole discretion, then the principal
     subject to LIBOR shall accrue or shall continue to accrue interest at the
     Prime Rate.

            (ii)    PROHIBITION OF MAKING, MAINTAINING, OR REPAYMENT OF
     PRINCIPAL AT LIBOR. If any treaty, statute, regulation, interpretation
     thereof, or any directive, guideline, or otherwise by a central bank or
     fiscal authority (whether or not having the force of law) shall either
     prohibit or extend the time at which principal subject to LIBOR may be
     purchased, maintained or repaid, all as determined by Lender in its sole
     discretion, then on as and of the date the prohibition becomes effective,
     the principal subject to that prohibition shall continue at the Prime Rate.

            (iii)   PAYMENTS OF PRINCIPAL AND INTEREST TO BE NET OF ANY TAXES OR
     COSTS. All payments of principal and interest shall be made net of any
     taxes and costs incurred by Lender resulting from having principal
     outstanding hereunder at LIBOR, as determined by Lender in its sole
     discretion. Without limiting the generality of the preceding obligation,
     illustrations of such taxes and costs are:

                    (A) Taxes (or the withholding of amounts for taxes) of any
            nature whatsoever including income, excise and interest equalization
            taxes (other than income taxes imposed by the United States or any
            state thereof on the income of Lender), as well as all levies,
            imposts, duties or fees whether now in existence or resulting from a
            change in, or promulgation of, any treaty, statute, regulation,
            interpretation thereof, or any directive, guideline or otherwise, by
            a central bank or fiscal authority (whether or not having the force
            of law) or a change in the basis of, or time of payment of, such
            taxes and other amounts resulting therefrom;

                    (B) Any reserve or special deposit requirements (other than
            any included within the definition of LIBOR set forth hereinabove)
            against assets or liabilities of, or deposits with or for the
            account of, Lender with respect to principal outstanding at LIBOR
            (including those imposed under Regulation D of the Federal Reserve
            Board) or resulting from a change in, or the promulgation of, such
            requirements by treaty, statute, regulation, interpretation thereof,
            or any directive, guideline, or otherwise by a central bank or
            fiscal authority (whether or not having the force of law);

                    (C) Any other costs resulting from compliance with treaties,
            statutes, regulations, interpretations or any directives or
            guidelines, or otherwise by a central bank or fiscal authority
            (whether or not having the force of law);

                               Page 32 of 82 Pages


                    (D) Any loss (including loss of anticipated profits) or
            expense incurred by reason of the liquidation or re-employment or
            deposits acquired by Lender to make advances or maintain the
            principal of any Loan or portion thereof outstanding at LIBOR:

                         (1)  As the result of a voluntary prepayment at a date
                    other than the maturity date selected for principal
                    outstanding at LIBOR; or

                         (2)  As the result of a mandatory repayment at a date
                    other than the maturity date selected for principal
                    outstanding at LIBOR as a result of Borrower exceeding any
                    applicable borrowing base or as the result of the occurrence
                    of an Event of Default and the acceleration of any portion
                    of the indebtedness hereunder; or

                         (3)  As the result of a prohibition on making,
                    maintaining, or prepaying principal outstanding at LIBOR.

                    If Lender incurs any such taxes or costs, Borrower, upon
     demand in writing specifying such taxes and costs, shall promptly pay them;
     save for manifest error, Lender's specification shall be presumptively
     deemed correct. All Loans made or carried at LIBOR shall be conclusively
     deemed to have been funded by on or behalf of Lender in the London
     interbank market by the purchase of deposits corresponding in amount and
     maturity to the amount and interest periods selected (or deemed to have
     been selected) by Borrower for such Loan hereunder.

     2.6.   MANDATORY REDUCTION OF REVOLVING COMMITMENT. Notwithstanding
anything to the contrary in this Agreement, the Revolving Commitment shall
terminate without notice of any kind on the Termination Date. Further, if at any
time prior to the Termination Date, and if Borrower has paid in full (and/or
Cash Collateralized, as the case may be) the Term Facility Amount, then if
Borrower (and/or Guarantor or any Pledgor, as the case may be) liquidates any
Collateral or sells any other assets of Borrower outside Borrower's ordinary
course of business, the proceeds from such liquidation and/or sale less
customary costs of sale or liquidation shall be applied to reduce the Revolving
Loans.

     2.7.   OPTIONAL TERMINATION OR REDUCTION. Borrower shall have the right
from time to time to reduce the Revolving Commitment, upon not less than 10
Business Days', or if pursuant to SECTION 6.11, upon 1 Business Day's prior
notice to Lender in writing or by telephonic, telecopy or facsimile
transmission, which notice shall specify the effective date of such termination
or reduction and shall be irrevocable and effective only upon receipt by Lender;
PROVIDED, HOWEVER, that after giving effect to any such termination or
reduction, (a) the aggregate principal amount of outstanding Revolving Loans
PLUS (b) the aggregate Stated Amount under all outstanding Revolving Letters of
Credit, shall not exceed the Revolving Commitment as then in effect. Any
optional reduction of the amount of the Revolving Commitment shall be in the
amount of $100,000 and in integral multiples of $10,000 in excess thereof or in
the full amount of the Revolving Commitment as then in effect. Any termination
or reduction pursuant to this SECTION 2.7 shall be permanent.

     2.8.   MANNER AND APPLICATION OF PAYMENTS. All payments in respect of the
Loans shall be in Dollars and in immediately available funds and shall be made
at the principal office of Lender prior to 2:00 p.m. Chicago time on the date of
the scheduled payment. All payments received after 2:00 p.m. Chicago time shall
be considered to have been received on the next Business Day. Any payment which
is to be made on a non-Business Day shall be rescheduled to the next succeeding
Business Day and interest, fees and other charges required to be paid in
connection with this Agreement shall continue to accrue to such rescheduled
Business Day. All payments of principal and interest and fees and other charges
required to be paid in connection with this Agreement in respect of the Loans
may be made by charging, and Borrower hereby authorizes Lender to charge, any of
Borrower's deposit accounts with Lender for

                               Page 33 of 82 Pages


the amount of each such payment. If Borrower shall not have sufficient collected
balances in such deposit accounts with Lender in order that each such payment
will be available when due hereunder, Borrower shall remain obligated to remit
any unpaid amounts due and owing and not collected from such deposit accounts.
If Borrower fails at any time and for any reason to have a deposit account with
Lender, all such payments shall be made directly to Lender at Lender's principal
office in immediately available funds.

     2.9.   FACILITY FEE. Borrower shall pay to Lender a facility fee (the
"FACILITY FEE") in immediately available funds for the period from the date
hereof to and including the Termination Date, such Facility Fee to be payable in
arrears on the last day of each calendar quarter, and on the Termination Date.
The Facility Fee shall be computed at a rate per annum of three-eighths of one
percent (3/8%) on the average daily amount of (a) the Revolving Commitment as in
effect from time to time, minus (b)(i) the aggregate unpaid principal amount of
all outstanding Revolving Loans, plus (ii) the aggregate Stated Amount of all
outstanding Revolving Letters of Credit, calculated on the basis of a year of
360 days, for actual days elapsed.

     2.10.  RESERVED.

     2.11.  INCREASED COSTS; LEGAL RESTRICTIONS. If, on or after the date
hereof, the introduction of any law, treaty, rule or regulation, or
determination of a court, governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof (whether or not
having the force of law), or any change therein or in the interpretation or
application thereof, shall:

     (a)    impose, modify or deem applicable any reserve, special deposit,
compensatory loan, deposit insurance, capital adequacy, minimum capital, capital
ratio or similar requirement against all or any assets held by, deposits or
accounts with, credit extended by or to, or commitments to extend credit or any
other acquisition of funds by, or Letters of Credit issued by, any office or
Affiliate of Lender, or impose on any office or Affiliate of Lender any other
condition affecting its making, renewing or maintaining any Loan or the
Revolving Commitment, or issuing or maintaining any Letter of Credit; or

     (b)    subject any office or Affiliate of Lender to, or cause the
termination or reduction of a previously granted exemption with respect to, any
tax, levy, impost, deduction, charge or withholding with respect to its making,
renewing or maintaining any Loan or issuing or maintaining any Letter of Credit,
or change the basis of taxation of payments to Lender of the principal of or
interest on the Loans or any other amounts under this Agreement or any of the
Loan Documents (except for taxes imposed on or measured by the overall net
income of Lender and imposed by the jurisdiction under the laws of which Lender
is organized or any political subdivision or agency thereof);

and the result of any of the foregoing events is to increase the cost to Lender
of maintaining the Revolving Commitment, or of making, renewing or maintaining
any Loan or issuing or maintaining any Letter of Credit, or to reduce the amount
of any sums received or receivable by Lender under this Agreement or any of the
Loan Documents or to reduce the rate of return on Lender's equity, then, in any
such case, Borrower promptly shall pay to Lender, upon delivery of the statement
referred to below, and indemnify and hold Lender harmless from and against any
such amount or amounts as may be necessary to compensate Lender for any such
additional cost, reduced benefit, reduced amount received or reduced rate of
return. If Lender sustains or incurs any additional cost, reduced benefit,
reduced amount received or reduced rate of return, Lender shall deliver to
Borrower a written statement of the nature and amounts thereof, which statement
shall be conclusive absent manifest error; PROVIDED, that the failure to provide
any such notice shall not affect the Obligations of Borrower under this SECTION
2.11. The Obligations of Borrower under this SECTION 2.11 shall survive and
continue to be in full force and effect notwithstanding (i) the execution and
delivery of this Agreement and the other Loan Documents, (ii) the making of the
Loans, (iii) the issuing of any Letter of Credit, (iv) the repayment of the
Loans, (v) the

                               Page 34 of 82 Pages


payment in full of all interest, fees and all other Obligations incurred
hereunder and under the other Loan Documents and (vi) the termination of all
Obligations of Lender under all Loan Documents; PROVIDED, HOWEVER, that the
Obligations of Borrower under this SECTION 2.11 shall terminate one year after
the Termination Date (except with respect to amounts due to Lender under this
SECTION 2.11 for which Borrower has received a written statement as provided
above).

                         ARTICLE III. LETTERS OF CREDIT

     3.1.   LETTERS OF CREDIT.

     (a)    Subject to the terms and conditions of this Agreement (including,
without limitation, the last sentence of SECTION 3.3), Lender agrees to issue
Letters of Credit for the account of Borrower from the Closing Date to but not
including the Termination Date at such times as Borrower may request; PROVIDED,
HOWEVER, that Lender shall not be obligated to (i) issue any Term Letter of
Credit other than those existing on the Closing Date; or (ii) issue any
Revolving Letter of Credit to the extent that after the issuance of such
Revolving Letter of Credit, (A) the sum of the aggregate principal amount of all
outstanding Revolving Loans plus the aggregate Stated Amount of all outstanding
Revolving Letters of Credit would exceed the Revolving Commitment or (B) the
outstanding Obligations would exceed the Collateral Base.

     (b)    Lender is under no obligation to issue any Revolving Letter of
Credit if:

            (i)     any order, judgment or decree of any governmental authority
     or arbitrator shall by its terms purport to enjoin or restrain Lender from
     issuing such Letter of Credit, or any requirement of law applicable to
     Lender or any request or directive (whether or not having the force of law)
     from any governmental authority with jurisdiction over Lender shall
     prohibit, or request that Lender refrain from, the issuance of letters of
     credit generally or such Letter of Credit in particular or shall impose
     upon Lender with respect to such Letter of Credit any restriction, reserve
     or capital requirement (for which Lender is not otherwise compensated
     hereunder) not in effect on the date hereof, or shall impose upon Lender
     any unreimbursed loss, cost or expense which was not applicable on the date
     hereof and which Lender in good faith deems material to it;

            (ii)    Lender has received written notice from Borrower on or prior
     to the Business Day prior to the requested date of issuance of such Letter
     of Credit, that one or more of the applicable conditions contained in
     SECTION 5 is not then satisfied;

            (iii)   the expiry date of any requested Letter of Credit (A) is
     more than 364 days after the date of issuance or (B) other than any Term
     Letter of Credit, falls on a date after the Termination Date;

            (iv)    the expiry date of any requested Letter of Credit is prior
     to the maturity date of any financial obligation to be supported by the
     requested Letter of Credit; PROVIDED, HOWEVER, this CLAUSE (iv) shall not
     be applicable in the event that the beneficiary, or its assigns, of the
     Letter of Credit shall have no right to draw on the Letter of Credit
     because the expiration date of the Letter of Credit has not been extended;

            (v)     any requested Letter of Credit does not provide for drafts,
     or is not otherwise in form and substance acceptable to Lender, or the
     issuance of a Letter of Credit shall violate any applicable policies of
     Lender;

            (vi)    any standby Letter of Credit is for the purpose of
     supporting the issuance of any letter of credit by any other Person; or

                               Page 35 of 82 Pages


            (vii)   such Letter of Credit is to be used for a purpose other than
     in connection with Borrower's or any of Borrower's Subsidiaries', as the
     case may be, existing lines of business.

     3.2.   MANNER OF ISSUANCE.

     connection with this Agreement, any Loan Document, the transactions
     contemplated herein or any unrelated transactions (including any underlying
     transactions between Borrower and the beneficiary named in any Letter of
     Credit);

            (iii)   Any draft, certificate or any other document presented under

     to be a trustee in

                               Page 37 of 82 Pages


     bankruptcy, debtor-in-possession, assignee for the benefit of creditors,
     liquidator, receiver or other representative of or successor to any
     beneficiary or any transferee of any Letter of Credit, including any
     payment arising in connection with (i) any case, action or proceeding
     before any court or other governmental authority relating to bankruptcy,
     insolvency, reorganization, arrangement, readjustment, liquidation,
     dissolution or similar proceeding, domestic or foreign, or (ii) Borrower
     making any general assignment for the benefit of its creditors,
     composition, marshalling of assets for creditors, or other similar
     arrangements in respect of its creditors generally or any substantial
     portion of its creditors, unless such payment was made due to Lender's
     willful misconduct or gross negligence; or

            (ix)    Any other event or circumstance that would, in the absence
     of this clause, result in the release or discharge by operation of law or

     covenant or agreement contained in this SECTION 3.5.

     3.6.   ROLE OF LENDER.

     (a)    Borrower agrees that, in paying any drawing under a Letter of
Credit, Lender shall not have any responsibility to obtain any document (other
than any drafts, certificates or other documents expressly required by the
Letter of Credit) or to ascertain or inquire as to the validity or accuracy of
any such document or the authority of the Person executing or delivering any
such document.

     (b)    Borrower hereby assumes all risks of the acts or omissions of any
beneficiary or transferee with respect to its use of any Letter of Credit;
PROVIDED, HOWEVER, that this assumption is not intended to, and shall not,
preclude Borrower's pursuing such rights and remedies as it may have against the
beneficiary or transferee at law or under any other agreement. Neither Lender
nor its officers, directors, employees or agents, nor any of the respective
correspondents, participants or assignees of Lender, shall be liable or
responsible for any of the matters described in CLAUSES (i) through (ix) of
SECTION 3.5(b); PROVIDED, HOWEVER, anything in such clauses to the contrary
notwithstanding, that Borrower may have a claim against Lender, and Lender may
be liable to Borrower, to the extent, but only to the extent, of any direct, as
opposed to consequential or exemplary, damages suffered by Borrower which
Borrower proves were caused by Lender's willful misconduct or gross negligence
or Lender's willful failure to pay under any Letter of Credit after the
presentation to it by the beneficiary of a sight draft and certificate(s)
strictly complying with the terms and conditions of a Letter of Credit. In
furtherance and not in limitation of the foregoing: (i) Lender may accept
documents that appear on their face to be in order, without responsibility for
further investigation, regardless of any notice or information to the contrary
and (ii) Lender shall not be responsible 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.

     3.7.   CASH COLLATERAL PLEDGE; REIMBURSEMENT OF L/C BORROWINGS. If, as of
the Termination Date, any Letters of Credit may for any reason remain
outstanding and partially or wholly undrawn, Borrower shall immediately (a) Cash
Collateralize the L/C Obligations pertaining to such Letters of Credit to the
extent that Borrower has the available cash on hand, and (b) to the extent that
any L/C Obligations have not been Cash Collateralized, take the necessary action
to ensure that such L/C Obligations (together with any other outstanding
Obligations) do not exceed the Collateral Base. Upon a Default or Event of
Default which is continuing, Borrower shall immediately Cash Collateralize all
L/C Obligations. Upon the occurrence of the circumstances described in SECTION
2.4(c) requiring Borrower to Cash Collateralize Letters of Credit, then Borrower
shall Cash Collateralize the Letters of Credit in accordance with the terms of
SECTION 2.4(c). If Lender has honored any full or partial drawing request on any
Letter of Credit and such drawing has resulted in an L/C Borrowing hereunder,
Borrower shall immediately reimburse Lender for such L/C Borrowing.

                               Page 38 of 82 Pages

Affiliate of Lender, Lender's attorneys or other advisors, or (b) any court,

jurisdiction over Lender, in connection with any proceeding, cause or matter
pending (or on its face purported to be pending) or in connection with any legal

assignee and any participant or prospective participant, all financial
statements, audit reports and other information pertaining to Borrower and its
Subsidiaries, whether such information was provided by Borrower or its
Subsidiaries or prepared or obtained by Lender or third parties.

any Event of Default, Default or breach of any provision, condition or covenant
of, or any amendment or modification to, this Agreement or any of the Loan
Documents must be in writing and shall be effective only to the extent it is set
forth in writing. No such waiver, permit, consent, approval, amendment or
modification shall be effective without the consent of Borrower and Lender. No
waiver of a specific breach, Event of Default or Default shall operate as a
waiver of any other breach, Event of Default or Default or of the same breach,

     9.3.   INDEMNIFICATION.

     (a)    TERMS OF INDEMNITY. Borrower agrees to indemnify and hold harmless
Lender, its directors, officers, counsel and employees and each Person, if any,
who controls Lender within the meaning of the Securities Act of 1933, as
amended, or the Securities Exchange Act of 1934, as amended (any and all of whom
are referred to in this SECTION 9.3 as the "INDEMNIFIED PARTIES" and
individually as an "INDEMNIFIED

                               Page 52 of 82 Pages


PARTY"), from and against any and all losses, claims, damages and liabilities,
joint or several (including all reasonable legal or other out-of-pocket expenses
reasonably incurred by any of the Indemnified Parties in connection with the
preparation for or defense of any pending or threatened claim, action or
proceeding, whether or not resulting in any liability (including reasonable
legal fees and expenses of attorneys which may be employees of Lender) to which
such Indemnified Party may become subject under any applicable Federal or state
law or otherwise, caused by or arising out of, or allegedly caused by or arising
out of, the preparation, review, negotiation, execution, delivery or performance
of this Agreement, the Loan Documents, the First Amendment to Trust Pledge
Agreement, the Sixth Amendment to Pledge Agreement (collectively, the
"AMENDMENTS") or any transaction contemplated hereby or thereby, other than
losses, claims, damages or liabilities arising from the gross negligence or
willful misconduct of the Indemnified Party. Promptly after receipt by an
Indemnified Party of notice of any claim, action or proceeding with respect to
which an Indemnified Party is entitled to indemnity hereunder, such Indemnified
Party will notify Borrower of such claim or the commencement of such action or
proceeding: PROVIDED, HOWEVER, that the failure of an Indemnified Party to give
notice as provided herein shall not relieve Borrower of its obligations under
this SECTION 9.3 with respect to such Indemnified Party, except to the extent
that Borrower actually is prejudiced by such failure. Borrower will assume the
defense of such claim, action or proceeding and will employ counsel reasonably
satisfactory to the Indemnified Party and will pay the fees and expenses of such
counsel. Notwithstanding the preceding sentence, the Indemnified Party will be
entitled, at the expense of Borrower, to employ counsel (and more than one if
reasonably necessary) separate from counsel for Borrower and for any other party
in such action if the Indemnified Party determines in its sole discretion that a
conflict of interest exists which makes representation by counsel chosen by
Borrower not advisable. In the event that an Indemnified Party is subpoenaed to
testify or produce documents in any action or proceeding brought against
Borrower or any of its Subsidiaries (or any of its officers, directors or
employees) in which such Indemnified Party is not named as a defendant (and is
not itself a plaintiff) or in which Borrower consents to such testimony or
production, Borrower agrees to reimburse such Indemnified Party for all
reasonable out-of-pocket expenses incurred by it (including reasonable fees and
expenses of counsel (which counsel may be an employee of the Lender) in
connection with its appearing as a witness or producing documents.

     (b)    SURVIVAL. The obligations of Borrower under this SECTION 9.3 shall
survive and continue to be in full force and effect notwithstanding (i) the
execution and delivery of this Agreement, the Loan Documents and the Amendments,
(ii) the making of the Loans, (iii) the repayment of the Loans, (iv) the
issuance of any Letter of Credit, (v) the payment in full of all interest, fees
and all other obligations incurred hereunder and under the Loan Documents and
(vi) the termination of all obligations of Lender to Borrower under all Loan
Documents.

     9.4.   INDEPENDENT INVESTIGATION. Lender shall be entitled to rely on all
representations and warranties made by Borrower under this Agreement in spite of
any independent investigation performed or to be performed by or on behalf of
Lender.

     9.5.   FAILURE OR DELAY. No failure or delay on the part of Lender in the
exercise of any power, right or privilege under this Agreement or any of the
Loan Documents and no course of dealing among Borrower and Lender shall operate
as a waiver thereof, nor shall any single or partial exercise of any such power,
right or privilege hereunder or thereunder preclude other or further exercise of
any other power, right or privilege.

     9.6.   SEVERABILITY. Any provision of this Agreement or the Loan Documents
which is prohibited or unenforceable in any jurisdiction shall be ineffective to
the extent of such prohibition or unenforceability, but all the remaining
provisions of this Agreement and the Loan Documents shall remain valid.

                               Page 53 of 82 Pages


assigns and any of Lender's participants; PROVIDED, HOWEVER, that Borrower may
not assign or transfer its rights or obligations under this Agreement without
the prior written consent of Lender, and no such consent shall in any event
relieve Borrower of its obligations hereunder.

for five (5) consecutive trading days. Borrower has also advised Lender that an
Event of Default has occurred and is continuing under SECTION 8.1(f) (Events of
Default) of this Agreement as a result of Borrower's Subsidiary, Freezing in
Florida, LLC, violating certain financial covenants under Section 4.1(u) of that
certain Letter of Credit and Reimbursement Agreement between Freezing in
Florida, LLC and Bank of America National Association dated as of September 1,
1999 for the periods ending June 30, 2001, September 30, 2001 and December 31,

extends for such specified time periods and in accordance with this SECTION 9.19

other Loan Document as a result of said Events of Default. Lender's waiver of
said Events of Default is limited to the specific facts giving rise to such

to any other failure to comply with the terms of SECTION 8.1 of this Agreement
or any other provisions of this Agreement.

SECTION 8.1 or any other provision of this Agreement.

            9.6.    SECTION 20 OF THE TRUST PLEDGE AGREEMENT. A new SECTION 20
is hereby added to the Trust Pledge Agreement as of the Effective Date to read
as follows:

     "20.   SPECIAL PROVISIONS REGARDING CONTROL AND/OR RESTRICTED STOCK
     PERTAINING TO RULE 144.

            (a) For purposes of this SECTION 20, "Related Person" means, from
     time to time:

                    (i)  any trust or estate in which Debtor owns ten percent
            (10%) or more of the total beneficial interest or of which it serves
            as trustee, executor or in any similar capacity; and

                    (ii) any corporation or other organization (other than Katy
            Industries, Inc., hereinafter referred to as the "ISSUER") in which
            Debtor or any person mentioned in (i) is the beneficial owner
            collectively of ten percent (10%) or more of any class of equity
            securities or ten percent (10%) or more of the equity interest.

            (b) Debtor represents and warrants that:

                    (i) Debtor is the legal, equitable and beneficial owner of
            603,000 shares of the common stock ("DEBTOR'S SHARES") of the
            Issuer, which includes the stock pledged as Collateral, free and
            clear of all liens, claims and encumbrances other than in favor of
            Secured Party. As of March 22, 2002, Debtor's Shares comprised
            approximately 7.2% of all outstanding shares of common stock of the
            Issuer (and constitutes approximately 3.0% as of March 22, 2002,
            assuming the conversion of 700,000 shares of convertible preferred
            stock, par value $100.00 per share, of the Issuer into 11,666,666
            shares of common stock of the Issuer as contemplated by the Stock
            Voting Agreement).

                    (ii) The Related Persons are the legal, equitable and
            beneficial owners of 2,378,081 shares of the common stock ("RELATED
            PERSONS' SHARES") of the Issuer. The Related Persons' Shares
            comprises approximately 28.3% of all outstanding shares of common
            stock of the Issuer as of March 22, 2002 (and constitutes
            approximately 11.9% as of March 22, 2002, assuming the conversion of
            700,000 shares of convertible preferred stock, par value $100.00 per
            share, of the Issuer into 11,666,000 shares of common stock of the
            Issuer as contemplated by the Stock Voting Agreement).

                    (iii) There are no stockholder agreements or other
            restrictions on, or laws, rules or regulations prohibiting or
            limiting, the sale or other disposition of Debtor's Shares other
            than restrictions under the Securities Act (including the type of
            restriction which can be removed by compliance with Securities and
            Exchange Commission Rule 144 ("RULE 144")) and state securities laws
            affecting the offering and sale by Persons such as Secured Party of
            securities such as the Debtor's Shares.

            (c) Debtor agrees to take or cause to be taken such actions, and to
     execute and deliver or cause to be executed and delivered such documents
     and instruments, all at Debtor's expense, as Secured Party may deem
     reasonably necessary or appropriate from time to time to cause a sale of
     Debtor's Shares in compliance with Rule 144; Debtor also

                               Page 71 of 82 Pages


     irrevocably authorizes Secured Party to take or cause to be taken such
     actions, and execute and deliver or cause to be executed and delivered such
     documents and instruments, on Debtor's behalf.

            (d) Debtor agrees not to sell or otherwise dispose of, and not to
     permit any Related Person to sell or otherwise dispose of, other than by
     gift to a person who is not a Related Person or an "affiliate" (as defined
     in Rule 144), Debtor's Shares and/or Related Persons' Shares with a value
     in excess of $250,000 in the aggregate during any calendar year. The sale
     of any of Debtor's Shares or Related Persons' Shares, the proceeds of
     which, less customary costs of sale or liquidation and taxes payable as a
     result of such sale, are used solely to pay down the Liabilities shall be
     specifically excluded in calculating the $250,000 in the immediately
     preceding sentence.

            (e) Debtor agrees to provide, or cause to be provided, to Secured
     Party such information and copies of documents as Secured Party may
     reasonably request concerning the amount, manner and other aspects of sales
     or other dispositions of Debtor's Shares or Related Persons' Shares of any
     nature whatsoever

            (f) As to any matter covered by or related to this SECTION 20, and
     without limiting Secured Party's rights under other terms of this
     Agreement, and after an Event of Default, Debtor, for itself and its
     successors, personal representatives and assigns, hereby irrevocably grants
     Secured Party a POWER OF ATTORNEY, with full power of substitution, to take
     actions (not inconsistent with the express terms of the Letter Agreement)
     and execute and deliver documents and instruments, in Debtor's name, place
     and stead, which power of attorney shall be deemed coupled with an
     interest. Debtor hereby ratifies all that Secured Party shall do, execute
     or deliver in accordance with such power of attorney.

            (g) Whenever the Issuer proposes to register any of its securities
     under the Securities Act of 1933, as amended (the "SECURITIES ACT"), and/or
     under any state securities law and the registration form to be used may be
     used for the registration of Debtor's Shares, Debtor shall use its
     reasonable best efforts to cause the Issuer to include Debtor's Shares in
     such registration. In connection with any such registration, (i) Debtor
     shall be responsible for all reasonable fees and expenses in connection
     with such registration (including for payment of Secured Party's reasonable
     expenses (including, without limitation, reasonable attorneys' fees) in
     connection with such registration), (ii) Debtor shall gives its full
     cooperation by doing such acts and providing such documents, statements and
     notices as reasonably required to give effect to the registration, (iii)
     Debtor shall provide copies of all documents, reports, statements and
     notices given to or received by the Debtor in connection with such
     registration to the Secured Party and (iv) Debtor shall indemnify Secured
     Party for any and all losses, claims, damages or liabilities that arise out
     of or are based upon any false statement or omission of facts or violation
     of any securities laws by Debtor or the Issuer in connection with the
     registration of any of Debtor's Shares."

            9.7.    SCHEDULE 1 TO THE TRUST PLEDGE AGREEMENT. A new SCHEDULE 1
is hereby added to the Trust Pledge Agreement to be in the form of the SCHEDULE
1 attached hereto as EXHIBIT A

Re:  Voting of Katy Industries Common Stock

Ladies and Gentlemen:

     It is our understanding that certain shareholders of Katy Industries, Inc.,
a Delaware corporation ("KATY"), including Wallace E. Carroll, Jr. ("CARROLL"),
CRL, Inc., a Delaware corporation ("CRL") and Wallace E. Carroll, Jr., and
Amelia M. Carroll, not individually but solely as trustees under Trust Agreement
dated May 1, 1958, as amended from time to time and known as the Wallace E. and
Lelia H. Carroll Trust for the benefit of Wallace E. Carroll, Jr. (the trustees
in their capacities as trustees under said trust and said trust, each and
collectively, referred to herein as the "Trust;" and, together with CRL, Carroll
and the other shareholders, the "SHAREHOLDERS"), have entered into that certain
Stock Voting Agreement with KKTY Holding Company, L.L.C., a Delaware limited
liability company ("KKTY"), dated as of June 2, 2001 (the "EFFECTIVE DATE"), a
fully executed copy of which is attached hereto (the "STOCK VOTING AGREEMENT"),
pursuant to which the Shareholders have jointly and severally agreed to vote (or
cause to be voted) 2,480,000 shares of common stock, $1 par value, of Katy
("COMMON STOCK") owned (whether of record or beneficially) by the Shareholders
as of the Effective Date (the "SECURITIES") with respect to certain questions
that may be put to the Shareholders, in each case, in accordance with the terms
and conditions of the Stock Voting Agreement (the "VOTE").

     Also pursuant to the Stock Voting Agreement, each Shareholder has
severally, and not jointly:

     1) appointed KKTY, and any designee of KKTY, each of them individually,
such Shareholder's proxy and attorney-in-fact, with full power of substitution
and resubstitution, to vote, to act by written consent or to request that the
chairman or secretary of Katy call a special meeting of the stockholders, during
the Closing Voting Period (as defined in the Stock Voting Agreement) with
respect to such Shareholder's Securities in accordance with the Vote (the
"PROXY");

     2) represented and warranted that any proxies previously given in respect
of such Shareholder's Securities are not irrevocable, and that all such proxies
have been or are revoked (the "REVOCATION"); and

     3) covenanted not to request that Katy register the transfer (book-entry or
otherwise) of any certificate or uncertificated interest representing any of
such Shareholder's Securities during the Closing Voting Period, unless such
transfer is made in compliance with the Stock Voting Agreement (the "STOP
TRANSFER").

                               Page 76 of 82 Pages


     Pursuant to that certain Pledge Agreement by and between CRL and The
Northern Trust Company, an Illinois banking corporation ("NORTHERN TRUST"),
dated as of December 31, 1995, as amended, restated, supplemented or otherwise
modified from time to time (the "CRL PLEDGE AGREEMENT"), CRL has pledged certain
shares of Common Stock to Northern Trust ("CRL PLEDGED SHARES") in order to
secure CRL's obligations under that certain Amended and Restated Revolving
Credit Agreement by and between CRL and Northern Trust, dated as of December 9,
1993, as amended, restated, supplemented or otherwise modified from time to time
(the "CREDIT AGREEMENT"). In addition, pursuant to that certain Pledge Agreement
by and between Carroll and Northern Trust dated as of February 28, 2001, as
amended, restated, supplemented or otherwise modified from time to time (the
"CARROLL PLEDGE AGREEMENT"), Carroll has pledged certain shares of Common Stock
to Northern Trust (the "CARROLL PLEDGED SHARES") in order to secure Carroll's
obligations under that certain Guaranty dated as of February 28, 2001 executed
and delivered by Carroll to and in favor of Northern Trust, as amended,
restated, supplemented or otherwise modified from time to time (the "GUARANTY").
Further, pursuant to that certain Pledge Agreement by and between the Trust and
Northern Trust dated as of February 28, 2001, as amended, restated, supplemented
or otherwise modified from time to time (the "TRUST PLEDGE AGREEMENT"), the
Trust has pledged certain shares of Common Stock to Northern Trust (the "TRUST
PLEDGED SHARES"; together with the CRL Pledged Shares and the Carroll Pledged
Shares, the "PLEDGED SHARES") in order to secure obligations of CRL to Northern
Trust under the Credit Agreement and to secure the Trust's obligations under the
Trust Pledge Agreement.

     CRL, Carroll and the Trust hereby represent and warrant to Northern Trust
that (i) the Recapitalization (as defined in the Stock Voting Agreement) has
occurred and been consummated in accordance with the terms of the
Recapitalization Agreement (as defined in the Stock Voting Agreement) and
therefore the Proxy, the Revocation and the Stop Transfer are no longer in
effect against the Shareholders and the Closing Voting Period has expired, and
(ii) the only remaining obligation under the Stock Voting Agreement is that of
the Shareholders, during the Convertible Voting Period (as defined in the Stock
Voting Agreement), to vote (or cause to be voted) the Securities in favor of the
election of all directors nominated by Katy's Board of Directors then in office,
including without limitation, each nominee for director designated by KKTY (such
remaining obligation referred to herein as the "CONVERTIBLE VOTING PERIOD
VOTE").

     Northern Trust has examined the Stock Voting Agreement and, notwithstanding
any provisions to the contrary in the CRL Pledge Agreement, the Credit
Agreement, the Carroll Pledge Agreement, the Guaranty, the Trust Pledge
Agreement or any other agreement related thereto and delivered in connection
therewith (collectively, the "LOAN AGREEMENTS"), effective as of the date
hereof, hereby approves of and authorizes the Convertible Voting Period Vote,
and hereby agrees to allow to be voted, in such manner as Carroll, CRL, the
Trust or KKTY shall direct, in accordance with the provisions of the Stock
Voting Agreement, so many of the shares of Common Stock as are subject to the
Loan Agreements. Northern Trust further agrees to cooperate with Carroll, CRL,
the Trust and the other Shareholders, at the expense of CRL, Carroll and the
Trust in connection with their respective efforts to fulfill any other
agreements and covenants set forth in the Stock Voting Agreement not
inconsistent with the Loan Agreements and this Letter.

     CRL, Carroll and the Trust hereby represent and warrant that none of them,
directly or indirectly, have received any consideration or remuneration in
exchange for entering into the Stock Voting Agreement. This Letter and the
consents herein shall terminate and be deemed withdrawn automatically upon the
expiration of the Convertible Voting Period.

     Any failure to comply with the terms of the Stock Voting Agreement shall be
deemed to constitute an immediate event of default or default for purposes of
the Loan Agreements, without further action or notice by Northern Trust and
Northern Trust may declare all obligations under the Loan Agreements immediately
due and payable.

                               Page 77 of 82 Pages


     This Letter shall be binding upon the successors, assigns, heirs, executors
and other legal representatives of the parties hereto. This Letter shall be
governed by and construed in accordance with the internal laws of the State of
Illinois.

     This Letter replaces and supercedes that certain letter agreement of
Northern Trust regarding the Stock Voting Agreement, dated as of June 2, 2001,
executed and delivered by Northern Trust and acknowledged and approved by CRL
and Carroll (the "PRIOR LETTER"). The terms, conditions and obligations of each
party to the Prior Letter shall terminate upon this letter being executed by all
parties hereto and this Letter shall control as to the terms, conditions and
obligations herein.

     Each reference in the CRL Pledge Agreement, the Carroll Pledge Agreement,
the Trust Pledge Agreement and any other Loan Agreement to the "Letter
Agreement" or like references shall be deemed to refer to this letter dated as
of August 31, 2001.

                                      Sincerely,

                                      THE NORTHERN TRUST COMPANY,
