     SECTION 2.1.  LOAN AMOUNT.

     (A)  Subject to the terms and conditions of this Agreement, on the date
upon which all of the terms and conditions of the Documents have been met or
fulfilled to Lender's satisfaction (the "Closing Date"), Lender agrees to make
loans to Borrower on a revolving basis (such loans being herein called
individually, a "Revolving Loan," and collectively, the "Revolving Loans") from
time to time in such amounts as Borrower may from time to time request up to an
aggregate amount outstanding of $15,000,000.00; provided, however, that: (i)
each borrowing by Borrower hereunder with respect to any Revolving Loan shall be
in the aggregate principal amount of at least $10,000.00; (ii) Lender's
commitment to make Revolving Loans shall remain in effect for a 364 day period
to and including March 8, 1999 (the "Revolver Termination Date"); (iii)
notwithstanding any provision herein to the contrary (1) upon the occurrence
and continuance of any Event of Default, and in each such event, the Lender
may, in its sole discretion, immediately cease to make Revolving Loans; and
(2) on the Revolver Termination Date, Borrower shall repay to the Lender all
Revolving Loans, plus interest accrued to the date of payment; and (iv) for a
period of at least 30 consecutive days at any time from the date hereof to the
Revolver Termination Date, the amount of Revolving Loans outstanding shall be
zero.

     (B)  The Lender agrees to issue letters of credit (individually, a "Letter
of Credit," and collectively, the "Letters of Credit") at the Borrower's request
on a revolving basis from time to time; provided, however, that: (a) in no event
shall total amount of Letters of Credit and Revolving Loans issued and
outstanding exceed $15,000,000.00; (b) all Letters of Credit shall expire prior
to the

                                                                       Page 3
<PAGE>

Revolver Termination Date; (c) Borrower shall immediately pay to Lender an
amount equal to all amounts drawn on a Letter of Credit, without notice or
demand by Lender, on the day such draw is paid by Lender; (d) all Letters of
Credit shall be in form and substance and in favor of beneficiaries
satisfactory to Lender; (e) no Letter of Credit shall be issued until
Borrower executes a properly completed application and agreement for such
Letter of Credit, in form satisfactory to Lender; (f) Borrower shall pay a
nonrefundable fee to Lender for each Letter of Credit in an amount equal to
the Letter of Credit amount multiplied by 75 basis points; and (g) no Letters
of Credit shall be issued upon the occurrence and continuance of any Event of
Default.  Interest on any amount owed by Borrower to Lender pursuant to this
Section 2.1(B) shall be paid upon demand, and shall accrue at the Prime Rate.
 Upon the occurrence and continuance of an Event of Default, interest shall
accrue and be payable of the Prime Rate plus 2%.

     SECTION 2.2.  USE OF LOAN PROCEEDS.  The proceeds of any borrowing by
Borrower pursuant to the Loans shall be used by Borrower solely to refinance
existing bank debt, provide working capital for joint venture investments, and
provide ongoing working capital support in the form of direct borrowings and
standby and trade letters of credit.

     SECTION 2.3.  REVOLVING NOTE.  The Revolving Loans shall be evidenced by a
promissory note (herein called the "Revolving Note") in the form attached
hereto, and made a part hereof, as Exhibit 2.3, dated the date first above
written, payable to the order of Lender, in the principal amount of
$15,000,000.00.  The date and amount of each Revolving Loan made by Lender and
of each repayment of principal thereon received by Lender shall be recorded by
Lender in its records and the aggregate unpaid principal amount shown on such
records shall be rebuttable, presumptive evidence of the principal owing and
unpaid on such Revolving Note.  The failure to record any such amount on such
records shall not, however, limit or otherwise affect the obligations of
Borrower hereunder or under the Revolving Note to repay the principal amount of
the Revolving Loans together with all interest accruing thereon.  The unpaid
principal amount from time to time outstanding on the Revolving Note shall, at
Borrower's choice, bear interest at either:  (a) the Prime Rate, adjusted as of
each change of the Prime Rate (each Revolving Loan bearing interest at such rate
a "Prime Rate Loan"); or (b) provided that an Event of Default has not occurred
and is not continuing, a rate per annum that shall be 75 basis points in excess
of the per annum rate of interest at which U.S. dollar deposits of an amount
comparable to the amount of the Revolving Loan and for a period equal to the
relevant Interest Period (as hereinafter defined) are offered generally to
Lender (rounded upward if necessary, to the nearest 1/16 of 1.0%)  in the London
Interbank Eurodollar market at 10:00 a.m. (London time) two Business Days prior
to the commencement of each Interest Period ("LIBOR" and each Revolving Loan
bearing interest at such rate a "LIBOR Loan"), such rate to remain fixed for
such Interest Period. "Interest Period" shall mean 30, 60, 90, or 180 day
periods as selected from time to time by the Borrower by irrevocable notice (in
writing, by telex, telegram or cable) given to Lender not less than two Business
Days prior to the first day of each respective Interest Period commencing on the
date hereof; provided that:  (i) each such Interest Period may be continued upon
its expiration by Borrower by irrevocable notice (in writing, by telex, telegram
or cable) given to Lender not less than two Business Days prior to the
expiration thereof, which notice shall specify that such Interest Period shall
continue for a one-month, two month or three month

                                                                       Page 4
<PAGE>

period; (ii) the final Interest Period shall be such that its expiration
occurs on or before the stated maturity date hereof; (iii) if for any reason
the Borrower shall fail to select time a period, then interest on such LIBOR
Loan shall accrue and be payable at the Prime Rate; and (iv) each such LIBOR
Loan shall be in an amount of at least $500,000.00, and shall be in
$100,000.00 increments.  "Business Day" shall mean any day other than a
Saturday, Sunday or a day on which banks in London, England, and Chicago,
Illinois, are required or permitted by law to close.

     Lender's determination of LIBOR as provided above shall be conclusive,
absent manifest error.  Further, if Lender determines in good faith (which
determination shall be conclusive, absent manifest error), prior to the
commencement of any Interest Period that:  (a) U.S. dollar deposits of
sufficient amount and maturity for funding the Revolving Loan are not available
to Lender in the London Interbank Eurodollar market in the ordinary course of
business; or (b) by reason of circumstances that affect the London Interbank
Eurodollar market, adequate and fair means do not exist to ascertain the rate of
interest to be applicable to the Revolving Loan, Lender may, at its sole and
absolute option, promptly notify the Borrower that interest on the Revolving
Loan shall be determined using the Prime Rate.

     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 governmental authority or any central bank or
other fiscal, monetary or other authority having jurisdiction over Lender or its
lending office (a "Regulatory Change"), shall, in the opinion of counsel to
Lender, make it unlawful for Lender to make or maintain the Revolving Loan
evidenced hereby, then Lender may, at its sole and absolute option, promptly
notify the Borrower that interest on the Revolving Loan shall be determined
using the Prime Rate.  If, for any reason, the Revolving Loan is paid prior to
the last Business Day of any Interest Period, the Borrower agrees to indemnify
Lender against any loss, including any loss on redeployment of the funds repaid,
cost or expense incurred by Lender as a result of such prepayment.  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, Lender; (b)
subject Lender or the Revolving Loan to any tax, duty, charge, stamp tax, or fee
or change the basis of taxation of payments to Lender of principal or interest
due from the Borrower to Lender hereunder (other than a change in the taxation
of the overall net income of Lender); or (c) impose on Lender any other
condition regarding the Revolving Loan or Lender's funding thereof, and Lender
shall determine (which determination shall be conclusive absent manifest error)
that the result of the foregoing is to increase the cost to Lender of making or
maintaining the Revolving Loan or to reduce the amount of principal and interest
received by Lender hereunder, then the Borrower shall pay to Lender, on demand,
such additional amounts as Lender shall, from time to time, determine are
sufficient to compensate and indemnify Lender for such increased costs or
reduced amount.

     Notwithstanding any provision in this Section 2.3 to the contrary, upon the
occurrence and continuance of an Event of Default, the Revolving Note shall bear
interest at a rate 2% in excess of the rate on Prime Rate Loans.  The accrued
interest on: (i) Prime Rate Loans shall be payable

                                                                       Page 5
<PAGE>

monthly on the first day of each month commencing with the first day of the
month while such Prime Rate Loan is outstanding; and (ii) LIBOR Loans shall
be payable the earlier to occur of 90 days or the maturity thereof; and in
all events on the basis of a year that consists of 360 days.

     SECTION 2.4.  OPTIONAL PREPAYMENT.  Borrower may from time to time, prepay
the Note in whole or in any part.  Prepayments of LIBOR Loans shall be made only
with payment of a penalty; provided, however, any partial prepayment shall be:
(a) applied to the unpaid installments thereof in the inverse order of maturity;
and (b) accompanied by accrued interest to the date of prepayment on the
principal amount being prepaid.

                    ARTICLE THREE.  NEGATIVE PLEDGE AND CONVEYANCE

     Borrower agrees that it will at all times neither: (a) sell, transfer,
convey, assign, hypothecate or dispose, whether by gift or otherwise, unless
such is made on an arm's length basis for fair market value; nor (b) create or
permit to exist any mortgage, pledge, title retention lien, or any other lien,
encumbrance or security interest, in and to its assets and properties, except as
provided in Article 4(E) and Section 5.1(E) hereof, whether such assets and
properties are now owned or existing, or hereafter existing or acquired.
Further, Borrower agrees not to grant a negative pledge obligation similar to
that provided in this Article Three to any individual or entity whatsoever,
other than to Lender as herein provided.

in its sole and arbitrary discretion, declare the principal of and interest on
the Revolving Loans and the Revolving Note, and all other amounts owed under the
Documents, to be immediately due and payable (and Letters of Credit to be
canceled) without presentment, demand, protest or other notice of any kind, all
of which are hereby expressly waived; and

     (B)  Lender may require Borrower to make its assets and the records
pertaining thereto, available to Lender for inspection and audit by Lender at
their then current location.

     SECTION 8.2.  REMEDIES ARE SEVERABLE AND CUMULATIVE.  All provisions
contained herein pertaining to any remedy of Lender shall be and are severable
and cumulative.  Any notification required pursuant to this Article Eight or
under applicable law shall be reasonably and properly given to Borrower at the

<PAGE>

     SECTION 9.1.  NO WAIVER; MODIFICATIONS IN WRITING.  Any failure or delay on
the part of Lender in exercising any right, power or remedy pursuant to the

exercise thereof, or the exercise of any other right, power or remedy. No
amendment, modification, supplement, termination or waiver of or to any
provision of the Documents, nor any consent to any departure by Borrower
therefrom, shall be effective unless the same shall be in writing and signed by
Lender.  Any waiver of any provision of the Documents and any consent to any
departure by Borrower from the terms of any provision of the Documents shall be
effective only in the specific instance and for the specific purpose for which

any other or further notice or demand in similar or other circumstances.

and apply toward payment of any of the Liabilities in such order of application

     SECTION 9.4.  COSTS, EXPENSES AND TAXES.  Borrower agrees to pay all fees
plus out-of-pocket expenses of Lender (including, without limitation, field
audit expenses and costs of outside consultants, appraisers, counsel and
paralegals to Lender) in connection with the preparation, administration and
enforcement of the Documents and the administration and enforcement of the
Loans.  If an Event of Default has occurred hereunder, Borrower shall pay any
and all stamp, transfer and other taxes payable or determined to be payable in
connection with the execution and delivery of the Documents and agrees to hold
Lender harmless from and against any and all liabilities with respect to or
resulting from any delay in paying or omission to pay such taxes.  If any
action, suit or proceeding arising from any of the foregoing is brought against
Lender, Borrower, to the extent and in the manner directed by Lender, will
resist and defend such action, suit or proceeding or cause the same to be
resisted and defended by counsel designated by Borrower (which counsel shall be
subject to the approval of Lender). If Borrower shall fail to do any act or
thing which it has covenanted to do under this Agreement or any representation
or warranty on the part of Borrower contained in this Agreement shall be
breached, Lender may, in its sole and arbitrary discretion, after 10 days
written notice is sent to Borrower, do the same or cause it to be done or remedy
any such breach, and may expend its funds for such purpose; and any and all
amounts so expended by Lender shall be repayable to Lender by Borrower
immediately upon Lender's demand therefor, with interest at the Prime Rate
during the period from and including the date funds are so expended by Lender,
to the date of repayment, and any such amounts due and owing Lender shall be an
additional obligation of Borrower to Lender.  The obligations of Borrower under
this Section 9.4 shall survive the termination of this Agreement and the
discharge of the other obligations of Borrower under the Documents. Any payment
required to be made pursuant to this Agreement not paid within five days of the
applicable due date shall be subject to a late charge which Borrower hereby
agrees to pay equal to the lesser of: (a) 5% of the overdue amount; or (b) the
maximum amount permitted by law.

     SECTION 9.5.  COMPUTATIONS.  Where the character or amount of any asset or
liability or item of income or expense is required to be determined, or any
consolidation or other accounting computation is required to be made, for the
purpose of this Agreement, such determination or

                                                                       Page 18
<PAGE>

calculation shall, to the extent applicable and except as otherwise specified
in this Agreement, be made in accordance with generally accepted accounting
principles applied on a basis consistent with those at the time in effect.

     SECTION 9.6.  FURTHER ASSURANCES.  Borrower agrees to do such further acts
and things and to execute and deliver to Lender such additional agreements,
documents and instruments as Lender may reasonably require or deem advisable to
carry into effect the purposes of the Documents, or to better assure and confirm

     SECTION 9.14.  JURISDICTION; WAIVERS.  BORROWER ACKNOWLEDGES THAT THIS
AGREEMENT IS BEING SIGNED BY LENDER IN PARTIAL CONSIDERATION OF LENDER'S RIGHT
TO ENFORCE IN THE JURISDICTION STATED BELOW THE TERMS AND PROVISION OF THIS
AGREEMENT AND THE DOCUMENTS.  BORROWER CONSENTS TO JURISDICTION IN THE STATE OF

AND ALL RIGHTS TO CONTEST SAID JURISDICTION AND VENUE.  LENDER AND BORROWER

     SECTION 9.15.  CAPITAL ADEQUACY INDEMNIFICATION.  If Lender shall determine
at any time after the date hereof that the adoption of any law, rule or
regulation regarding capital adequacy, or any change therein or in the
interpretation or administration thereof by any governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by Lender with any request or directive regarding capital
adequacy (whether or not having the force of law) from any such authority,
central bank or comparable agency, has or would have the effect of reducing the
rate of return on Lender's capital as a consequence of its obligations hereunder
to a level below that which Lender could have achieved but for such adoption,
change or compliance (taking into consideration Lender's policies with respect
to capital adequacy) by an amount deemed by Lender to be material, then the
Borrower shall pay to Lender upon demand such amount or amounts, in addition to
the amounts payable under the other provisions of this Agreement or under the
Note, as will compensate Lender for such reduction.  Determinations by Lender
for purposes of this Section 9.15 of the additional amount or amounts required
to compensate lender in respect of the foregoing shall be conclusive in the

this Section 9.15.

received by lender on account of any obligations owed by Borrower to Lender and

payments received by Lender to the obligations in any order or manner as Lender
may deem advisable, including, without limitation, the continuing exclusive
right to apply and reapply such proceeds and payments in any order or manner as
lender may deem advisable.

     SECTION 9.17. INDEMNIFICATION.  Except for any Indemnified Liabilities (as

acts or omissions, and in consideration of the execution and delivery of the
Documents by Lender and agreement of Lender to make the Loans hereunder,
Borrower hereby agrees to indemnify, exonerate and hold Lender and each of its
officers, directors, employees, attorneys and agents (collectively, the "Bank
Parties"), free and harmless from any against any and all actions, causes of
action, suits, losses, liabilities and damages, and expenses in connection
therewith, including, without limitation, reasonable attorneys' fees and
disbursements (the "Indemnified Liabilities"), incurred by the Bank Parties, or
any of them, as a result of, or arising out of, or relating to:  (a) any
transaction financed or to be financed in whole or in part directly or
indirectly with the proceeds of any Revolving Loan; (b) the execution and
delivery of the Documents by Borrower; (c) Borrower's possession, use, operation

obligations of Borrower under this Section 9.17 shall survive any termination of
this Agreement.

     SECTION 9.18. ENVIRONMENTAL WARRANTY AND INDEMNITY.  Borrower hereby
represents and warrants to Lender that it, occupies the property(ies) more fully
described on Exhibit 9.18 attached hereto and made a part hereof (collectively,
the "Property").  Borrower hereby represents and warrants to Lender that
collectively, no hazardous or toxic substances, within the meaning of any
applicable statute or regulation, whether federal, state or local, are presently
stored or otherwise located on the Property in violation of Environmental Laws.
Borrower covenants and agrees with Lender that while any Liabilities are
outstanding, all toxic substances within the definition of Environmental Laws,
which may be used by any person for any purpose upon the Property, shall be used
or stored thereon in accordance with all laws, regulations, and requirements for
such storage promulgated by any governmental authority, and that the Property
will not be used for the principal purpose of storing such substances.

     Borrower hereby agrees to give Lender immediate notice of any violation or
suspected violation of any federal, state, or local statute, rule, or regulation
dealing with the presence or suspected presence of any hazardous, toxic, or
environmentally dangerous substances or condition affecting the Property.
Borrower hereby unconditionally gives Lender the right, but not the obligation,
and Lender does not so obligate itself, to undertake to contain and clean up
releases of hazardous substances on the Property before the costs of doing so
exceeds the value of the Property.  Upon the written request of Lender to
Borrower, Lender, its attorneys, employees, agents or other persons or entities
designated by Lender, shall, from time to time and at any time, be allowed to
enter upon the Property and conduct environmental examinations and environmental
audits of the Property, all in form, manner and type as Lender may then require
in its sole discretion.  Borrower shall fully cooperate and make the Property,
all improvements on the Property and the land which is the subject of the
Property available to Lender at such times as Lender may request in order to
conduct such environmental examinations and environmental audits.

                                                                       Page 21

     Borrower hereby indemnifies and saves Lender harmless of and from any and
all loss, costs (including reasonable attorneys' fees), liability and damage
whatsoever incurred by Lender, by reason of any violation by Borrower of any
applicable statute, rule or regulation for the protection of the environment
which occurs upon the Property or any adjacent parcels of real estate that
affect the Property or by reason of the imposition of any governmental lien for
the recovery of environmental cleanup costs expended by reason of such
violation; provided however, that to the extent Lender is strictly liable under
any such statute, Borrower's obligation to Lender under this indemnity shall
likewise be without regard to fault on the part of the undersigned with respect
to the violation of law which results in liability to Lender.  Borrower further
agrees that this indemnity and the representations and warranties contained
herein shall continue and remain in full force and effect beyond the term of the
Liabilities and shall be terminated only when there is no further obligation of
any kind whether in law or equity or otherwise of Lender in connection with any
such environmental clean-up costs, environmental liens, or environmental matters
involving the Property.

     IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
duly executed and delivered at Chicago, Illinois, as of the date first above
written.
