               (ii)  elect, as of the last day of the applicable Interest
          Period, to continue any Eurodollar Loans having Interest Periods
          expiring on such day (or any part thereof in an aggregate amount not
          less than $500,000 or a higher integral multiple of $100,000) for a
          new Interest Period;

provided that after giving effect to any repayment, conversion or continuation,
--------
the aggregate principal amount of each Group of Eurodollar Loans shall be at
least $500,000 and an integral multiple of $100,000.

          (b)  The Company shall give written or telephonic (followed
immediately by written confirmation thereof) notice to Lender of each proposed
conversion or continuation not later than (i) in the case of conversion into
Base Rate Loans, 11:00 A.M., Chicago time, on the proposed date of such
conversion and (ii) in the case of conversion into or continuation of Eurodollar
Loans, 11:00 A.M., Chicago time, at least three Business Days prior to the
proposed date of such conversion or continuation, specifying in each case:

               (i)  the proposed date of conversion or continuation;

               (ii)  the aggregate amount of Loans to be converted or continued;

               (iii) the type of Loans resulting from the proposed conversion or
          continuation; and

               (iv)  in the case of conversion into, or continuation of,
          Eurodollar Loans, the duration of the requested Interest Period
          therefor.

          (c)  If upon the expiration of any Interest Period applicable to
Eurodollar Loans, the Company has failed to select timely a new Interest Period
to be applicable to such Eurodollar Loans, the Company shall be deemed to have
elected to convert such Eurodollar Loans into Base Rate Loans effective on the
last day of such Interest Period.

          (d) Lender will, if no timely notice is provided by the Company,
notify the Company of the details of any automatic conversion.

          (e)  Any conversion of a Eurodollar Loan on a day other than the last
day of an Interest Period therefor shall be subject to Section 8.4.

SECTION 3 NOTE EVIDENCING LOANS.

     3.1  Note.  The Loans shall be evidenced by a promissory note (the "Note")
          ----                                                           ----
substantially in the form set forth in Exhibit A, with appropriate insertions,
                                       ---------
payable to the order of Lender in a face principal amount equal to the Revolving
Commitment Amount.  Each Revolving Loan shall be paid in full on the Termination
Date.

     3.2  Recordkeeping.  Lender shall record in its records, or at its option
          -------------
on the schedule attached to its Note, the date and amount of each Loan made by
it, each repayment or conversion thereof and, in the case of each Eurodollar
Loan, the dates on which each Interest Period for such Loan shall begin and end.
The aggregate unpaid principal amount so recorded shall be rebuttable
presumptive evidence of the principal amount owing and unpaid on such Note.  The
failure to so record any such amount or any error in so recording any such
amount shall not, however, limit or otherwise affect the obligations of the
Company hereunder or under any Note to repay the principal amount of the Loans
evidenced by such Note together with all interest accruing thereon.

SECTION 4  INTEREST.

     4.1  Interest Rates.  The Company promises to pay interest on the unpaid
          --------------
principal amount of each Loan for the period commencing on the date of such Loan
until such Loan is paid in full as follows:

     (a) at all times while such Loan is a Base Rate Loan, at a rate per annum
equal to the sum of the Base Rate from time to time in effect plus the Base Rate
Margin from time to time in effect; and

     (b) at all times while such Loan is a Eurodollar Loan, at a rate per annum
equal to the sum of the Eurodollar Rate (Reserve Adjusted) applicable to each
Interest Period for such Loan plus the Eurodollar Margin from time to time in
effect;

provided that at any time an Event of Default exists, if requested by Lender,
--------
the interest rate applicable to each Loan shall be increased by two percent
(2.0%).

     4.2  Interest Payment Dates.  Accrued interest on each Base Rate Loan shall
          ----------------------
be payable in arrears on the last day of each month and at maturity.  Accrued
interest on each Eurodollar Loan shall be payable on the last day of each
Interest Period relating to such Loan and at maturity.  After maturity, accrued
interest on all Loans shall be payable on demand.  If the date on which any
interest payment is due in accordance herewith is not a Business Day, then such
payment shall be due on the next day immediately following that is a Business
Day and interest shall continue to accrue.

     4.3  Setting and Notice of Eurodollar Rates.  The applicable Eurodollar
          --------------------------------------
Rate for each Interest Period shall be determined by Lender, and notice thereof
shall be given by Lender

                                       14
<PAGE>

promptly to the Company. Each determination of the applicable Eurodollar Rate by
Lender shall be conclusive and binding upon the parties hereto, in the absence
of demonstrable error. Lender shall, upon written request of the Company,
deliver to the Company a statement showing the computations used by Lender in
determining any applicable Eurodollar Rate hereunder.

     4.4  Computation of Interest.  Interest shall be computed for the actual
          -----------------------
number of days elapsed on the basis of a year of 360 days.  The applicable
interest rate for each Base Rate Loan shall change simultaneously with each
change in the Base Rate.

SECTION 5  FEES.

     5.1  Non-Use Fee.  The Company agrees to pay to Lender a non-use fee, for
          -----------
the period from the Closing Date to the Termination Date, at the Non-Use Fee
Rate in effect from time to time of the unused amount of the Revolving
Commitment Amount.  For purposes of calculating usage under this Section, the
Revolving Commitment Amount shall be deemed used to the extent of the aggregate
principal amount of all outstanding Revolving Loans.  Such non-use fee shall be
payable in arrears on the last day of each calendar quarter and on the
Termination Date for any period then ending for which such non-use fee shall not
have previously been paid.  The non-use fee shall be computed for the actual
number of days elapsed on the basis of a year of 360 days.

     5.2  Intentionally Omitted.
          ---------------------

     5.3  Upfront Fees.  The Company agrees to pay to Lender on the Closing Date
          ------------
an upfront fee in the amount equal to $240,000, representing 2.00% of the

            --------------------------------------------------------------
Amount.  The Company may from time to time on at least five Business Days' prior

written notice received by Lender permanently reduce the Revolving Commitment
Amount to an amount not less than the Revolving Outstandings.  Any such
reduction shall be in an amount not less than $500,000 or a higher integral
multiple of $100,000.  Concurrently with any reduction of the Revolving
Commitment Amount to zero, the Company shall pay all interest on the Revolving
Loans, and all non-use fees.

     6.1.2  Mandatory Reductions of Revolving Commitment Amount.  On the date of
            ---------------------------------------------------

        (ii)   Concurrently with the receipt by the Company or any Subsidiary of
               any Net Cash Proceeds from any issuance of equity securities of

                                  ------------
               such Net Cash Proceeds.

     (b) If on any day on which the Revolving Commitment Amount is reduced
pursuant to Section 6.1.2 the Revolving Outstandings exceed the Revolving
            -------------
Commitment Amount, the Company shall immediately repay Revolving Loans in an
amount sufficient to eliminate such excess.

                                       16
<PAGE>

     6.3  All Repayments.  Any partial repayment or prepayment of a Group of
          --------------

                               -----------

SECTION 7  MAKING AND PRORATION OF PAYMENTS; SETOFF; TAXES.

     7.1  Making of Payments.  All payments of principal of or interest on the
          ------------------
Note, and of all fees, shall be made by the Company to Lender in immediately
available funds at the office specified by Lender not later than noon, Chicago
time, on the date due; and funds received after that hour shall be deemed to
have been received by Lender on the following Business Day.

     7.2  Application of Certain Payments.  Each payment of principal shall be
          -------------------------------
applied to such Loans as the Company shall direct by notice to be received by
Lender on or before the date of such payment or, in the absence of such notice,
as Lender shall determine in its discretion.

     7.3  Due Date Extension.  If any payment of principal or interest with
          ------------------
respect to any of the Loans, or of any fees, falls due on a day which is not a
Business Day, then such due date shall be extended to the immediately following
Business Day (unless, in the case of a Eurodollar Loan, such immediately
following Business Day is the first Business Day of a calendar month, in which
case such due date shall be the immediately preceding Business Day) and, in the
case of principal, additional interest shall accrue and be payable for the
period of any such extension.

     7.4  Setoff.  The Company agrees that Lender has all rights of set-off and
          ------
bankers' lien provided by applicable law, and in addition thereto, the Company
agrees that at any time any Event of Default exists, Lender may apply to the
payment of any obligations of the Company hereunder, whether or not then due,
any and all balances, credits, deposits, accounts or moneys of the Company then
or thereafter with Lender.

     7.5  Intentionally Omitted.
          ---------------------

     7.6  Taxes.  All payments of principal of, and interest on, the Loans and
          -----
all other amounts payable hereunder shall be made free and clear of and without
deduction for any present or future income, excise, stamp or franchise taxes and
other taxes, fees, duties, withholdings or other charges of any nature
whatsoever imposed by any taxing authority, excluding franchise taxes and taxes
imposed on or measured by Lender's net income or receipts (all non-excluded
items being called "Taxes").  If any withholding or deduction from any payment
                    -----
to be made by the Company hereunder is required in respect of any Taxes pursuant
to any applicable law, rule or regulation, then the Company will:

          (a) pay directly to the relevant authority the full amount required to
     be so withheld or deducted;

                                       17
<PAGE>

          (b) promptly forward to Lender an official receipt or other
     documentation satisfactory to Lender evidencing such payment to such
     authority; and

          (c) pay to Lender such additional amount or amounts as is necessary to
     ensure that the net amount actually received by Lender will equal the full
     amount Lender would have received had no such withholding or deduction been
     required.

Moreover, if any Taxes are directly asserted against Lender with respect to any
payment received by Lender hereunder, Lender may pay such Taxes and the Company
will promptly pay such additional amounts (including any penalty, interest or
expense) as is necessary in order that the net amount received by such Person
after the payment of such Taxes (including any Taxes on such additional amount)
shall equal the amount such Person would have received had such Taxes not been
asserted.

     If the Company fails to pay any Taxes when due to the appropriate taxing
authority or fails to remit to Lender the required receipts or other required
documentary evidence, the Company shall indemnify Lender for any incremental
Taxes, interest or penalties that may become payable by Lender as a result of
any such failure.

SECTION 8 INCREASED COSTS; SPECIAL PROVISIONS FOR EURODOLLAR LOANS.

     8.1  Increased Costs.  (a)  If, after the date hereof, the adoption of, or
          ---------------
any change in, any applicable law, rule or regulation, or any change in the
interpretation or administration of any applicable law, rule or regulation by
any governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by Lender (or any
Eurodollar Office of Lender) with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency

          (i)  shall subject Lender (or any Eurodollar Office of Lender) to any
     tax, duty or other charge with respect to its Eurodollar Loans, its Note or
     its obligation to make Eurodollar Loans, or shall change the basis of
     taxation of payments to Lender of the principal of or interest on its
     Eurodollar Loans or any other amounts due under this Agreement in respect
     of its Eurodollar Loans or its obligation to make Eurodollar Loans (except
     for changes in the rate of tax on the overall net income of Lender or its
     Eurodollar Office imposed by the jurisdiction in which Lender's principal
     executive office or Eurodollar Office is located);

          (ii)  shall impose, modify or deem applicable any reserve (including
     any reserve imposed by the FRB, but excluding any reserve included in the
     determination of interest rates pursuant to Section 4), special deposit or
                                                 ---------
     similar requirement against assets of, deposits with or for the account of,
     or credit extended by Lender  (or any Eurodollar Office of Lender); or

                                       18
<PAGE>

          (iii)  shall impose on Lender (or its Eurodollar Office) any other
     condition affecting its Eurodollar Loans, its Note or its obligation to
     make Eurodollar Loans;

and the result of any of the foregoing is to increase the cost to (or to impose
a cost on) Lender (or any Eurodollar Office of Lender) of making or maintaining
any Eurodollar Loan, or to reduce the amount of any sum received or receivable
by Lender (or its Eurodollar Office) under this Agreement or under its Note with
respect thereto, then upon demand by Lender (which demand shall be accompanied
by a statement setting forth the basis for such demand and a calculation of the
amount thereof in reasonable detail, a copy of which shall be furnished to
Lender), the Company shall pay directly to Lender such additional amount as will
compensate Lender for such increased cost or such reduction.

     (b) If Lender shall reasonably determine that any change in, the adoption
or phase-in of, any applicable law, rule or regulation regarding capital
adequacy, or any change 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 or any Person
controlling Lender with any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on Lender's or such controlling Person's capital as a consequence of Lender's
obligations hereunder to a level below that which Lender or such controlling
Person could have achieved but for such change, adoption, phase-in or compliance
(taking into consideration Lender's or such controlling Person's policies with
respect to capital adequacy) by an amount deemed by Lender or such controlling
Person to be material, then from time to time, upon demand by Lender (which
demand shall be accompanied by a statement setting forth the basis for such
demand and a calculation of the amount thereof in reasonable detail, a copy of
which shall be furnished to Lender), the Company shall pay to Lender such
additional amount as will compensate Lender or such controlling Person for such
reduction.

     8.2  Basis for Determining Interest Rate Inadequate or Unfair.  If with
          --------------------------------------------------------
respect to any Interest Period:

          (a) deposits in Dollars (in the applicable amounts) are not being
     offered to Lender in the interbank eurodollar market for such Interest
     Period, or Lender otherwise reasonably determines (which determination
     shall be binding and conclusive on the Company) that by reason of
     circumstances affecting the interbank Eurodollar market adequate and
     reasonable means do not exist for ascertaining the applicable Eurodollar
     Rate; or

          (b) the making or funding of Eurodollar Loans has become impracticable
     as a result of an event occurring after the date of this Agreement which in
     the opinion of Lender materially affects such Loans;

                                       19
<PAGE>

then Lender shall promptly notify the Company thereof and, so long as such
----
circumstances shall continue, (i) Lender shall not be under any obligation to
make or convert into Eurodollar Loans and (ii) on the last day of the current
Interest Period for each Eurodollar Loan, such Loan shall, unless then repaid in
full, automatically convert to a Base Rate Loan.

     8.3  Changes in Law Rendering Eurodollar Loans Unlawful.  If any change in,
          --------------------------------------------------
or the adoption of any new, law or regulation, or any change in the
interpretation of any applicable law or regulation by any governmental or other
regulatory body charged with the administration thereof, should make it (or in
the good faith judgment of Lender cause a substantial question as to whether it
is) unlawful for Lender to make, maintain or fund Eurodollar Loans, then Lender
shall promptly notify the Company and, so long as such circumstances shall
continue, (a) Lender shall have no obligation to make or convert into Eurodollar
Loans (but shall make Base Rate Loans concurrently with the making of or
conversion into Eurodollar Loans by Lender which are not so affected, in each
case in an amount equal to the amount of Eurodollar Loans which would be made or
converted into by Lender at such time in the absence of such circumstances) and
(b) on the last day of the current Interest Period for each Eurodollar Loan of
Lender (or, in any event,  on such earlier date as may be required by the
relevant law, regulation or interpretation), such Eurodollar Loan shall, unless
then repaid in full, automatically convert to a Base Rate Loan.  Each Base Rate
Loan made by Lender which, but for the circumstances described in the foregoing
sentence, would be a Eurodollar Loan (an "Affected Loan") shall remain
                                          -------------
outstanding for the same period as the Group of Eurodollar Loans of which such
Affected Loan would be a part absent such circumstances.

     8.4  Funding Losses.  The Company hereby agrees that upon demand by Lender
          --------------
(which demand shall be accompanied by a statement setting forth the basis for
the amount being claimed, a copy of which shall be furnished to Lender), the
Company will indemnify Lender against any net loss or expense which Lender may
sustain or incur (including any net loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by Lender to
fund or maintain any Eurodollar Loan), as reasonably determined by Lender, as a
result of (a) any payment, prepayment or conversion of any Eurodollar Loan of
Lender on a date other than the last day of an Interest Period for such Loan
(including any conversion pursuant to Section 8.3) or (b) any failure of the
                                      -----------
Company to borrow, convert or continue any Loan on a date specified therefor in
a notice of borrowing, conversion or continuation pursuant to this Agreement.
For this purpose, all notices to Lender pursuant to this Agreement shall be
deemed to be irrevocable.  Without limiting the generality of the foregoing,
upon (i) any default by the Company in making any borrowing of, conversion into
or continuation of any Eurodollar Loan following the Company's delivery to
Lender of any request in respect thereof or (ii) any payment of a Eurodollar
Loan on any day that is not the last day of the Interest Period applicable
thereto (regardless of the source of such prepayment and whether voluntary, by
acceleration or otherwise), the Company shall pay Lender an amount equal to the
amount of any losses, expenses and liabilities (including, without limitation,
any loss (including interest paid) sustained by Lender in connection with the
re-employment of such funds) that Lender may sustain as a result of such default
or such payment.

<PAGE>

     8.5  Right of Lender to Fund through Other Offices.  Lender may, if it so
          ---------------------------------------------
elects, fulfill its commitment as to any Eurodollar Loan by causing a foreign
branch or Affiliate of Lender to make such Loan; provided that in such event for
                                                 --------
the purposes of this Agreement such Loan shall be deemed to have been made by
Lender and the obligation of the Company to repay such Loan shall nevertheless
be to Lender and shall be deemed held by it, to the extent of such Loan, for the
account of such branch or Affiliate.

     8.6  Discretion of Lender as to Manner of Funding.  Notwithstanding any
          --------------------------------------------
provision of this Agreement to the contrary, Lender shall be entitled to fund
and maintain its funding of all or any part of its Loans in any manner it sees
fit, it being understood, however, that for the purposes of this Agreement all
determinations hereunder (including with respect to subsections 8.5 above) shall
be made as if Lender had actually funded and maintained each Eurodollar Loan
during each Interest Period for such Loan through the purchase of deposits
having a maturity corresponding to such Interest Period and bearing an interest
rate equal to the Eurodollar Rate for such Interest Period.

     8.7  Mitigation of Circumstances.  Lender shall promptly notify the Company
          ----------------------------
of any event of which it has knowledge which will result in, and will use
reasonable commercial efforts available to it (and not, in Lender's sole
judgment, otherwise disadvantageous to Lender) to mitigate or avoid, (i) any
obligation by the Company to pay any amount pursuant to Section 7.6 or 8.1 or

Agreement and the Note are due and payable (as a result of acceleration or
otherwise), each Participant shall be deemed to have the right of setoff in
respect of its participating interest in amounts owing under this Agreement and

owing directly to it as a lender under this Agreement or such note.  The Company
also agrees that each Participant shall be entitled to the benefits of Section
                                                                       -------

willful misconduct of the party from which recovery is sought.  Lender shall not
have any liability with respect to, and the Company hereby waives, releases and
agrees not to sue for, any special, indirect or consequential damages suffered
by the Company in connection with, arising out of, or in any way related to the
