applicable cure period, interest on funds outstanding hereunder shall accrue at
the Default Rate. All interest and fees, if any, payable hereunder shall be
computed for the actual number of days elapsed on the basis of a year consisting
of three hundred sixty (360) days. Bank is authorized to rely on the oral or
written loan requests, including telecopy or telegraphic loan requests, which
Bank believes in its good faith judgment to emanate from a properly authorized
representative of Borrower, whether or not that is in fact the case.

         4.       Prime Loans. A request by Borrower for a Prime Loan must be
received no later than 11:00 a.m. Chicago, Illinois time, on the day such Prime
Loan (a) is to be advanced by Bank or (b) shall begin to bear interest at the
Prime Rate. Interest on the unpaid principal balance of Prime Loans shall be
payable, in arrears, beginning on June 1, 2004 and continuing on the first day
of each month thereafter, and on the Maturity Date. Prime Loans may be prepaid
in whole or in part, together with all accrued interest thereon to the date of
such prepayment, at any time without premium or penalty.

         5.       LIBOR Loans. Each LIBOR Loan must be in the minimum amount of
$500,000.00 or an integral multiple thereof. A request by Borrower for a LIBOR
Loan must be

<PAGE>

received by Bank no later than 11:00 a.m. Chicago, Illinois time, two Business
Days before the Business Day on which such LIBOR Loan is to be funded. Interest
on the unpaid principal balance of each LIBOR Loan shall accrue through, but not
including, the last day of each Interest Period and shall be payable on (i) the
last Business Day of the relevant Interest Period for each such LIBOR Loan (and,
in the case of a LIBOR Loan having an Interest Period of six-months, on the last
day of the third month of such Interest Period), (ii) the date of any principal
repayment of the amount paid, (iii) at maturity of the Note, and (iv) after
maturity (whether by acceleration or otherwise) on demand from Bank.

         6.       Provisions Relating to LIBOR Loans.

         (a) Notwithstanding anything to the contrary contained herein, the
principal balance of any LIBOR Loan may not be prepaid in whole or in part at
any time. If, for any reason, a LIBOR Loan is paid prior to the last Business
Day of any Interest Period, whether voluntary, involuntary, by reason of
acceleration or otherwise, each such prepayment of a LIBOR Loan will be
accompanied by the amount of accrued interest on the amount prepaid and any and
all costs, expenses, penalties and charges incurred by Bank as a result of the
early termination or breakage of a LIBOR Loan, plus the amount, if any, by which
(i) the additional interest which would have been payable during the Interest
Period on the LIBOR Loan prepaid had it not been prepaid, exceeds (ii) the
interest which would have been recoverable by Bank by placing the amount prepaid
on deposit in the domestic certificate of deposit market, the eurodollar deposit
market, or other appropriate money market selected by Bank, for a period
starting on the date on which it was prepaid and ending on the last day of the
Interest Period for such LIBOR Loan. The amount of any such loss or expense
payable by Borrower to Bank under this section shall be determined in Bank's
sole discretion based upon the assumption that Bank funded its loan commitment
for LIBOR Loans in the London Interbank Eurodollar market and using any
reasonable attribution or averaging methods which Bank deems appropriate and
practical, provided, however, that Bank is not obligated to accept a deposit in
the London Interbank Eurodollar market in order to charge interest on a LIBOR
Loan at the LIBOR Rate.

         (b) If Bank determines in good faith (which determination shall be
conclusive, absent manifest error) prior to the commencement of any Interest
Period that (i) United States dollar deposits of sufficient amount and maturity
for funding any LIBOR Loan are not available to Bank in the London Interbank
Eurodollar market in the ordinary course of business, or (ii) by reason of
circumstances affecting the London Interbank Eurodollar market, adequate and
fair means do not exist for ascertaining the rate of interest to be applicable
to the relevant LIBOR Loan, Bank shall promptly notify Borrower thereof and, so
long as the foregoing conditions continue, advances under the Note may not be
advanced as a LIBOR Loan thereafter. In addition, at Borrower's option, each
existing LIBOR Loan shall be immediately (y) converted to a Prime Loan on the
last Business Day of the then existing Interest Period, or (z) due and payable
on the last Business Day of the then existing Interest Period, without further
demand, presentment, protest or notice of any kind, all of which are hereby
waived by Borrower.

         (c) If after the date hereof, the introduction of, or any change in any
applicable law, treaty, rule, regulation or guideline or in the interpretation
or administration thereof by any


                                       6
<PAGE>

governmental authority or any central bank or other fiscal, monetary or other
authority having jurisdiction over Bank or its lending office (a "Regulatory
Change") shall, in the reasonable determination of Bank, make it unlawful for
Bank to make or maintain the LIBOR Loans, then Bank shall promptly notify
Borrower and advances under the Note may not be advanced as a LIBOR Loan
thereafter. In addition, at Borrower's option, each existing LIBOR Loan shall be
immediately (i) converted to a Prime Loan on the last Business Day of the then
existing Interest Period or on such earlier date as required by law, or (ii) due
and payable on the last Business Day of the then existing Interest Period or on
such earlier date as required by law, all without further demand, presentment,
protest or notice of any kind, all of which are hereby waived by Borrower.

         (d) If any Regulatory Change (whether or not having the force of law)
shall (A) impose, modify or deem applicable any assessment, reserve, special
deposit or similar requirement against assets held by, or deposits in or for the
account of or loans by, or any other acquisition of funds or disbursements by,
Bank; (B) subject Bank or any LIBOR Loan to any tax, duty, charge, stamp tax or
fee or change the basis of taxation of payments to Bank of principal or interest
due from Borrower to Bank hereunder (other than a change in the taxation of the
overall net income of Bank); or (C) impose on Bank any other condition regarding
such LIBOR Loan or Bank's funding thereof, and Bank shall reasonably determine
(which reasonable determination shall be conclusive, absent manifest error) that
the result of the foregoing is to increase the cost to Bank of making or
maintaining such LIBOR Loan or to reduce the amount of principal or interest
received by Bank hereunder, then Borrower shall (i) pay to Bank, on demand, such
additional amounts as Bank shall, from time to time, determine are sufficient to
compensate and indemnify Bank for such increased cost or reduced amount, or (ii)
convert each LIBOR Loan to a Prime Loan, provided that Borrower shall remain
liable for such additional amounts incurred by Bank prior to conversion to a
Prime Loan and such conversion shall be treated as a prepayment of a LIBOR Loan
if it occurs prior to expiration of the applicable Interest Period.

         7.       Letters of Credit.

         (a) Upon the execution and delivery by Borrower and the acceptance by
Bank, in its sole and absolute discretion, of Bank's standard Master Letter of
Credit Agreement and application(s) therefor, Bank agrees to issue for the
account of Borrower, such Letters of Credit in the standard form of Bank and
otherwise in form and substance acceptable to Bank, from time to time during the
term of this Note, provided that the Letter of Credit Obligations plus the FX
Obligations may not at any time exceed the FX/LC Sublimit and provided, further,
that no Letter of Credit shall have an expiration date later than May 21, 2006.
The amount of any payments made by Bank with respect to draws made by a
beneficiary under a Letter of Credit for which Borrower has failed to reimburse
Bank upon the earlier of (i) Bank's demand for repayment, or (ii) five (5) days
from the date of such payment to such beneficiary by Bank, shall be deemed to
have been converted to a Prime Loan as of the date such payment was made by Bank
to such beneficiary. Upon the occurrence of a default and at the option of Bank,
all Letter of Credit Obligations shall be converted to Prime Loans, all without
demand, presentment, protest or notice of any kind, all of which are hereby
waived by Borrower.


                                       7

<PAGE>


         (b) Borrower shall pay to Bank an annual fee equal to three-quarters of
one percent (0.75%) of the face amount of each standby Letter of Credit, payable
by Borrower upon the issuance of each Letter of Credit and annually thereafter,
until (i) such Letter of Credit has expired or has been returned to Bank, or
(ii) Bank has paid the beneficiary thereunder the full face amount of such
Letter of Credit. All Letters of Credit shall bear Bank's usual and customary
fees contained in Bank's standard letter of credit fee schedule.

         (c) In the event that any Letter of Credit Obligations are outstanding
upon the termination and/or expiration of this Note, as amended or replaced from
time to time, Borrower shall, upon demand, deposit with Bank in a cash
collateral account an amount equal to the aggregate amount of such Letter of
Credit Obligations. Bank may apply any interest accruing on such cash collateral
account until the Letter of Credit Obligations and any and all obligations
hereunder shall have been fulfilled without the consent of Borrower.

         8.  Foreign Exchange Transactions.

         (a) Upon the execution and delivery by Borrower and the acceptance by
Bank, in its sole and absolute discretion, of Bank's standard documentation
therefor ("FX Documents"), Bank agrees to engage in FX Transactions for the
account of Borrower, from time to time during the term of this Note, provided
that (i) the FX Obligations plus the Letter of Credit Obligations may not at any
time exceed the FX/LC Sublimit, (ii) the MDDR may not exceed the MDDR Sublimit,
and (iii) no FX Transaction shall have an expiration date later than the
Maturity Date. The amount of any payments made by Bank with respect to FX
Transactions for which Borrower has failed to reimburse Bank in accordance with
the FX Documents shall be deemed to have been converted to a Prime Loan as of
the date such payment was made by Bank. Upon the occurrence of a default and at
the option of Bank, the FX Obligations shall be converted to Prime Loans, all
without demand, presentment, protest or notice of any kind, all of which are
hereby waived by Borrower.

         (b)  Borrower  shall pay to Bank  Bank's  usual and  customary  fees in
connection with FX Transactions.

         9. Collection of Funds. Principal payments submitted in funds not
available until collected shall continue to bear interest until collected. If
payment hereunder becomes due and payable on a Saturday, Sunday or legal holiday
under the laws of the United States or the State of Illinois, the due date
thereof shall be extended to the next succeeding Business Day, and interest
shall be payable thereon at the rate specified during such extension.

         10. Evidence of the Obligations. This Note is executed pursuant to a
revolving line of credit under which Borrower is indebted to Bank and evidences
the aggregate unpaid principal amount of all advances made or to be made by Bank
to Borrower under the Note. All advances, credit accommodations and repayments
hereunder shall be evidenced by entries on the books and records of Bank which
shall be presumptive evidence of the principal amount and interest owing and
unpaid on this Note, or any renewal or extension hereof. The failure to so
record any such amount or any error so recording any such amount shall not,
however, limit or otherwise affect


                                       8
<PAGE>

the obligations of Borrower hereunder or under any other documents or instrument
to repay the principal amount of the Obligations together with all interest and
fees accruing thereon.

         11. Authorized Persons. Loans under this Note may be made by Bank upon
oral or written request of any person which Bank in its good faith judgment
believes to be a properly authorized representative of Borrower, whether or not
that is in fact the case. Any such Loans shall be conclusively presumed to have
been made by Bank to or for the benefit of Borrower. Borrower does hereby
irrevocably confirm, ratify and approve all such advances by Bank and does
hereby indemnify Bank against losses and expenses (including court costs,
attorneys' and paralegals' fees) and shall hold Bank harmless with respect
thereto.

         12. Loan Fee.  In addition to the other fees described herein, Borrower
agrees to pay to Bank a loan fee in the amount of Fifty Thousand and 00/100
Dollars ($50,000.00) due and payable upon the execution of this Note by Borrower
and its acceptance by Bank.

         13. Representations and Warranties.  To induce Bank to make the loans
evidenced by this Note, Borrower hereby makes the following representations and
warranties to Bank.

                  (a) Organization. Borrower is a corporation duly organized,
         existing and in good standing under the laws of the State of Delaware,
         with full and adequate power to carry on and conduct its business as
         presently conducted, and is duly licensed or qualified in all foreign
         jurisdictions wherein the nature of its activities require such
         qualification or licensing.

                  (b) Authorization; Validity. Borrower has full right, power
         and authority to enter into this Note, to make the borrowings and
         execute and deliver any other document or agreement to be entered into
         by Borrower in connection with this Note (collectively, the "Loan
         Documents") and to perform all of its duties and obligations under this
         Note and the other Loan Documents. The execution and delivery of this
         Note and the other Loan Documents will not, nor will the observance or
         performance of any of the matters and things herein or therein set
         forth, violate or contravene any provision of law, the articles of
         incorporation or bylaws of Borrower. All necessary and appropriate
         action has been taken on the part of Borrower to authorize the
         execution and delivery of this Note. This Note is a valid and binding
         agreement and contract of Borrower in accordance with its terms. No
         basis presently exists for any claim against Bank under this Note, the
         other Loan Documents, and the enforcement of this Note and the other
         Loan Documents is subject to no defenses of any kind.

                  (c) Absence of Breach. The execution, delivery and performance
         of this Note, the other Loan Documents and any other documents or
         instruments to be executed and delivered by Borrower in connection with
         this Note shall not: (i) violate any provisions of law or any
         applicable regulation, order, writ, injunction or decree of any court
         or governmental authority, or (ii) conflict with, be inconsistent with,
         or result in any breach or default of any of the terms, covenants,
         conditions, or provisions of any indenture, mortgage, deed of trust,
         instrument, document, agreement or contract of any kind to


                                       9
<PAGE>

         which Borrower is a party or by which Borrower or any of its property
         or assets may be bound.

                  (d) Adverse Conditions. To the best of Borrower's knowledge,
         no condition, circumstance, document, restriction, litigation or
         proceeding (or threatened litigation or proceeding or basis therefor)
         exists which could materially adversely affect the ability of any of
         Borrowers to perform the obligations under the Loan Documents, which
         would constitute a Default hereunder or which would constitute a
         Default with the giving of notice or lapse of time or both.

                  (e) Compliance with Laws. The nature and transaction of the
         business and operations of Borrower, and the use of its property and
         assets, including, but not limited to, the present use and occupancy of
         all real property owned by Borrower, will not violate or conflict with
         any applicable law, statute, ordinance, rule, regulation or order of
         any kind including without limitation zoning, building, environmental,
         land use, noise abatement, occupational health and safety or other
         laws, any building permit or any condition, grant, easement, covenant,
         condition or restriction, whether recorded or not.

                  (f) Business Purpose. The proceeds of this Note will be used
         for the purposes specified in 815 ILCS 205/4(1)(c), as amended from
         time to time; and that the principal obligation evidenced hereby and
         secured by the other Loan Documents constitutes a business loan within
         the purview and operation of said section.

                  (g) Use of Proceeds. Neither Borrower nor any affiliate of
         Borrower, shall use any portion of the proceeds of the Note, either
         directly or indirectly, for the purpose of (i) purchasing any
         securities underwritten or privately placed by ABN AMRO Incorporated,
         an affiliate of Bank, or (ii) purchasing or carrying any margin stock,
         within the meaning of Regulation U as adopted by the Board of Governors
         of the Federal Reserve System or any successor thereto.

         14. Covenants.  Until all of the Obligations of Borrower to Bank
hereunder shall have been paid in full, Borrower shall:

                  (a) at all times maintain Tangible Net Worth in the minimum

                  were not incurred in connection with the borrowing of money or
                  the obtaining of an advance or credit, and which do not in the
                  aggregate materially detract from the value of its property or
                  assets or materially impair the use thereof in the operation
                  of its business;

                           (iii) liens arising out of judgments or awards

         hereunder;

                  (c) Borrower shall make any assignment for the benefit of

         16. Miscellaneous.

         (a) BORROWER WAIVES THE BENEFIT OF ANY LAW THAT WOULD OTHERWISE

<PAGE>

REGARDLESS OF THE COLLATERAL, AT ANY TIME AFTER DEFAULT AND EXPIRATION OF ANY
APPLICABLE CURE PERIOD, ANY INDEBTEDNESS MATURED OR UNMATURED, OWING FROM BANK
TO BORROWER. BANK MAY, FROM TIME TO TIME, WITHOUT DEMAND OR NOTICE OF ANY KIND,

ASSETS, OF OR IN THE NAME OF BORROWER THEN OR THEREAFTER WITH BANK.

         (b) BANK AND BORROWER, AND EACH ONE OF THEM, KNOWINGLY, VOLUNTARILY AND
INTENTIONALLY WAIVE IRREVOCABLY, THE RIGHT EITHER OR ANY MAY HAVE TO TRIAL BY

AGREEMENT, EXECUTED OR CONTEMPLATED TO BE EXECUTED IN CONJUNCTION HEREWITH OR

         (c) Except as otherwise set forth herein, Borrower waives any and all
presentment, demand, notice of dishonor, protest, and all other notices and
demands in connection with the enforcement of Bank's rights hereunder. No
default shall be waived by Bank except in writing. No delay on the part of Bank
in the exercise of any right or remedy shall operate as a waiver thereof, and no
single or partial exercise by Bank of any right or remedy shall preclude other
or further exercise thereof, or the exercise of any other right or remedy. This
Note: (i) is valid, binding and enforceable in accordance with its provisions,
and no conditions exist to the legal effectiveness of this Note; (ii) contains
the entire agreement between Borrower and Bank; (iii) is the final expression of
their intentions; and (iv) supersedes all negotiations, representations,
warranties, commitments, offers, contracts (of any kind or nature, whether oral
or written) prior to or contemporaneous with the execution hereof. No prior or
contemporaneous representations, warranties, understandings, offers or
agreements of any kind or nature, whether oral or written, have been made by
Bank or relied upon by Borrower in connection with the execution hereof. No
modification, discharge, termination or waiver of any of the provisions hereof
shall be binding upon Bank, except as expressly set forth in a writing duly
signed and delivered on behalf of Bank.

         (d) The non-prevailing party agrees to pay all costs, legal expenses,
attorneys' fees and paralegals' fees of every kind, paid or incurred by the
prevailing party in enforcing its rights hereunder, including, but not limited
to, litigation or proceedings initiated under the United States Bankruptcy Code,
or in respect to any other of the Obligations or in defending against any
defense, cause of action, counterclaim, setoff or crossclaim based on any act of
commission or omission by Bank with respect to this Note or any other of the
Obligations promptly on demand of Bank or other person paying or incurring the

provisions of this Note.

         (g) Borrower acknowledges and agrees that the lending relationship
hereby created with Bank is and has been conducted on an open and arm's length
basis in which no fiduciary relationship exists and that Borrower has not relied

         (h) As used herein, all provisions shall include the masculine,
feminine, neuter, singular and plural thereof, wherever the context and facts
