the Facility B Lenders in integral multiples of $250,000, upon at least two
Business Days' written notice to the Agent, which notice shall specify the
amount of any such reduction; provided, however, that the amount of the
Aggregate Facility B Commitment may not be reduced below the Facility B
Principal Obligations Amount.

         2.6 Minimum Amount of Each Advance. Each Eurodollar Advance shall be in
the minimum amount of $100,000 (and in multiples of $50,000 if in excess
thereof), and each Floating Rate Advance shall be in the minimum amount of
$100,000 (and in multiples of $50,000 if in excess thereof); provided, however,
that (i) any Floating Rate Advance may be in

                                      -19-
<PAGE>   21
the amount of the unused Aggregate Total Commitment, and (ii) any Floating Rate
Advance to be applied to the Borrower's reimbursement obligation pursuant to
Section 2.18.3(a) or to pay interest on Indebtedness shall be in the amount of
such reimbursement obligation or interest, as the case may be.

         2.7 Optional Principal Payments. The Borrower may from time to time
pay, without penalty or premium, all outstanding Floating Rate Advances, or, in
a minimum aggregate amount of $100,000 or any integral multiple of $50,000 in
excess thereof, any portion of the outstanding Floating Rate Advances upon two
Business Days' prior written notice to the Agent. A Eurodollar Advance may not
be paid prior to the last day of the applicable Interest Period. All prepayments
made under this Section 2.7 shall be applied first to any Advances outstanding
under Facility B, and second to principal installments under Facility A in the
inverse order of maturity.

         2.8 Method of Selecting Types and Interest Periods for New Advances.
The Borrower shall select the Type of Advance and, in the case of each
Eurodollar Advance, the Interest Period applicable to each Advance from time to
time. The Borrower shall give the Agent irrevocable notice (a "Borrowing
Notice") not later than 10:00 a.m. (Chicago time) at least one Business Day
before the Borrowing Date of each Floating Rate Advance and three Business Days
before the Borrowing Date for each Eurodollar Advance, specifying:

                  (i) the Facility under which such Advance is to be borrowed,

                  (ii) the Borrowing Date, which shall be a Business Day, of
such Advance,

                  (iii) the aggregate amount of such Advance,

                  (iv) the Type of Advance selected, and

                  (v) in the case of each Eurodollar Advance, the Interest
Period applicable thereto.

Not later than noon (Chicago time) on each Borrowing Date, each Lender shall
make available its Loan or Loans, in funds immediately available in Chicago to
the Agent at its address specified pursuant to Article XIII. The Borrower hereby
authorizes the Agent to disburse the proceeds of each Advance into the
Borrower's general deposit account maintained at First Chicago, unless the
Borrower instructs the Agent otherwise in writing.

         2.9 Conversion and Continuation of Outstanding Advances. Floating Rate
Advances shall continue as Floating Rate Advances unless and until such Floating
Rate Advances are converted into Eurodollar Advances. Each Eurodollar Advance
shall continue as a Eurodollar Advance until the end of the then applicable
Interest Period therefor, at which time such Eurodollar Advance shall be
automatically converted into a Floating Rate Advance unless the Borrower shall
have given the Agent a Conversion/Continuation Notice requesting that, at the
end of such Interest Period, such Eurodollar Advance either continue as a
Eurodollar Advance for the same or another Interest Period or be converted into
a Floating Rate Advance. Subject to

                                      -20-
<PAGE>   22
the terms of Section 2.6, the Borrower may elect from time to time to convert
all or any part of an Advance of any Type into any other Type or Types of
Advances; provided that any conversion of any Eurodollar Advance shall be made
on, and only on, the last day of the Interest Period applicable thereto. The
Borrower shall give the Agent irrevocable notice (a "Conversion/Continuation
Notice") of each conversion of an Advance or continuation of a Eurodollar
Advance not later than 10:00 a.m. (Chicago time) at least one Business Day, in
the case of a conversion into a Floating Rate Advance, or three Business Days,
in the case of a conversion into or continuation of a Eurodollar Advance, prior
to the date of the requested conversion or continuation, specifying:

                  (i) the requested date which shall be a Business Day, of such
conversion or continuation;

                  (ii) the aggregate amount and Type of the Advance which is to
be converted or continued; and

                  (iii) the amount and Type(s) of Advance(s) into which such
Advance is to be converted or continued and, in the case of a conversion into or
continuation of a Eurodollar Advance, the duration of the Interest Period
applicable thereto.

         2.10 Changes in Interest Rate, Etc. Each Floating Rate Advance shall
bear interest on the outstanding principal amount thereof, for each day from and
including the date such Advance is made or is converted from a Eurodollar
Advance into a Floating Rate Advance pursuant to Section 2.9 to but excluding
the date it becomes due or is converted into a Eurodollar Advance pursuant to
Section 2.9, at a rate per annum equal to the Floating Rate for such day.
Changes in the rate of interest on that portion of any Advance maintained as a
Floating Rate Advance will take effect simultaneously with each change in the
Alternate Base Rate. Each Eurodollar Advance shall bear interest from and
including the first day of the Interest Period applicable thereto to (but not
including) the last day of such Interest Period at the Eurodollar Rate
determined as applicable to such Eurodollar Advance. No Interest Period may end
after the Facility Termination Date. The Borrower shall select Interest Periods
so that it is not necessary to repay any portion of a Eurodollar Advance prior
to the last day of the applicable Interest Period in order to make a mandatory
repayment required pursuant to Section 2.2.1.

         2.11 Rates Applicable After Default. Notwithstanding anything to the
contrary contained in Section 2.8 or 2.9, during the continuance of a Default or
Unmatured Default the Required Lenders may, at their option, by notice to the
Borrower (which notice may be revoked at the option of the Required Lenders
notwithstanding any provision of Section 8.2 requiring unanimous consent of the
Lenders to changes in interest rates), declare that no Advance may be made as,
converted into or continued as a Eurodollar Advance. If any Advance (or portion
thereof) is not paid when due, whether pursuant to any of Sections 2.2.1 through
2.2.5, by acceleration or otherwise, the Required Lenders may, at their option,
by notice to the Borrower (which notice may be revoked at the option of the
Required Lenders notwithstanding any provision of Section 8.2 requiring
unanimous consent of the Lenders to changes in interest rates), declare that all
Advances shall bear interest at a rate per annum equal to the Floating Rate

                                      -21-
<PAGE>   23
otherwise applicable to the Floating Rate Advances plus 3% per annum until such
Advance (or portion thereof) is paid in full.

         2.12 Method of Payment. All payments of the Obligations hereunder shall
be made, without setoff, deduction, or counterclaim, in immediately available
funds to the Agent at the Agent's address specified pursuant to Article XIII, or
at any other Lending Installation of the Agent specified in writing by the Agent
to the Borrower, by noon (Chicago time) on the date when due and shall be
applied ratably by the Agent among the Lenders to whom such Obligations are due.
Each payment delivered to the Agent for the account of any Lender shall be
delivered promptly by the Agent to such Lender in the same type of funds that
the Agent received at its address specified pursuant to Article XIII or at any
Lending Installation specified in a notice received by the Agent from such
Lender. The Agent is hereby authorized to charge the account of the Borrower
maintained with First Chicago for each payment of principal, interest and fees
as it becomes due hereunder.

         2.13 Noteless Agreement; Evidence of Indebtedness. (a) Each Lender
shall maintain in accordance with its usual practice an account or accounts
evidencing the indebtedness of the Borrower to such Lender resulting from each
Loan made by such Lender from time to time, including the amounts of principal
and interest payable and paid to such Lender from time to time hereunder.

         (b) The Agent shall also maintain accounts in which it will record (i)
the amount of each Loan made hereunder, the Type thereof and the Interest Period
with respect thereto, (ii) the amount of any principal or interest due and
payable or to become due and payable from the Borrower to each Lender hereunder
and (iii) the amount of any sum received by the Agent hereunder from the
Borrower and each Lender's share thereof.

         (c) The entries maintained in the accounts maintained pursuant to
paragraphs (a) and (b) above shall be prima facie evidence of the existence and
amounts of the Obligations therein recorded; provided, however, that the failure
of the Agent or any Lender to maintain such accounts or any error therein shall
not in any manner affect the obligation of the Borrower to repay the Obligations
in accordance with their terms.

         (d) Any Lender may request that its Loans under either Facility be
evidenced by a promissory note (a "Note"). In such event, the Borrower shall
prepare, execute and deliver to such Lender a Note evidencing its Loans under
such Facility payable to the order of such Lender in a form supplied by the
Agent. Thereafter, the Loans evidenced by such Note and interest thereon shall
at all times (including after any assignment pursuant to Section 12.3) be
represented by one or more Notes payable to the order of the payee named therein
or any assignee pursuant to Section 12.3, except to the extent that any such
Lender or assignee subsequently returns any such Note for cancellation and
requests that such Loans once again be evidenced as described in paragraphs (a)
and (b) above.

         (e) The Borrower hereby authorizes the Lenders and the Agent to extend,
convert or continue Advances and effect selections of Types of Advances based on
telephonic notices made

                                      -22-
<PAGE>   24
by any person or persons the Agent or any Lender in good faith believes to be
acting on behalf of the Borrower and the Agent shall, absent written
instructions from an Authorized Officer to the contrary, deposit the proceeds of
such Advances in the Borrower's operating account with the Agent. The Borrower
agrees to deliver promptly to the Agent a written confirmation, if such
confirmation is requested by the Agent or any Lender, of each telephonic notice
signed by an Authorized Officer. If the written confirmation differs in any
material respect from the action taken by the Agent and the Lenders, the records
of the Agent and the Lenders shall govern absent manifest error.

         2.14 Interest Payment Dates; Interest and Fee Basis. Interest accrued
on each Floating Rate Advance shall be payable on each Payment Date, commencing
with the first such date to occur after the Effective Date, and at maturity.
Interest accrued on each Eurodollar Advance shall be payable on the last day of
its applicable Interest Period, on any date on which the Eurodollar Advance is
prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued
on each Eurodollar Advance having an Interest Period longer than three months
shall also be payable on the last day of each three-month interval during such
Interest Period. Interest, commitment fees and letter of credit fees shall be
calculated for actual days elapsed on the basis of a 360-day year. Interest
shall be payable for the day an Advance is made but not for the day of any
payment on the amount paid if payment is received prior to noon (Chicago time)
at the place of payment. If any payment of principal of or interest on an
Advance shall become due on a day which is not a Business Day, such payment
shall be made on the next succeeding Business Day and, in the case of a
principal payment, such extension of time shall be included in computing
interest in connection with such payment.

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

         2.16 Lending Installations. Each Lender may book its Loans at any
Lending Installation selected by such Lender and may change its Lending
Installation from time to time. All terms of this Agreement shall apply to any
such Lending Installation and any Notes held by any Lender shall be deemed held
by such Lender for the benefit of such Lending Installation. Each Lender may, by
written notice to the Agent and the Borrower, designate a Lending Installation
through which Loans will be made by it and for whose account Loan payments are
to be made.

         2.17 Non-Receipt of Funds by the Agent. Unless the Borrower or a
Lender, as the case may be, notifies the Agent prior to the date on which it is
scheduled to make payment to the Agent of (i) in the case of a Lender, the
proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal
or interest to the Agent for the account of any Lenders, that it does not intend
to make such payment, the Agent may assume that such payment has been made. The

                                      -23-
<PAGE>   25
Agent may, but shall not be obligated to, make the amount of such payment
available to the intended recipient in reliance upon such assumption. If such
Lender or the Borrower, as the case may be, has not in fact made such payment to
the Agent, the recipient of such payment shall, on demand by the Agent, repay to
the Agent the amount so made available together with interest thereon in respect
of each day during the period commencing on the date such amount was so made
available by the Agent until the date the Agent recovers such amount at a rate
per annum equal to (i) in the case of payment by a Lender, the Federal Funds
Effective Rate for such day or (ii) in the case of payment by the Borrower, the
interest rate applicable to the relevant Loan.

         2.18 Facility Letters of Credit.

                  2.18.1 Issuance of Facility Letters of Credit. (a) From and
after the Effective Date, the Issuing Lender agrees, upon the terms and
conditions set forth in this Agreement, to issue at the request and for the
account of the Borrower, one or more Facility Letters of Credit; provided,
however, that the Issuing Lender shall not be under any obligation to issue, and
shall not issue, any Facility Letter of Credit if (i) any order, judgment or
decree of any governmental authority or other regulatory body with jurisdiction
over the Issuing Lender shall purport by its terms to enjoin or restrain the
Issuing Lender from issuing such Facility Letter of Credit, or any law or
governmental rule, regulation, policy, guideline or directive (whether or not
having the force of law) from any governmental authority or other regulatory
body with jurisdiction over the Issuing Lender shall prohibit, or request that
the Issuing Lender refrain from, the issuance of Facility Letters of Credit in
particular or shall impose upon the Issuing Lender with respect to any Facility
Letter of Credit any restriction or reserve or capital requirement (for which
the Issuing Lender is not otherwise compensated) or any unreimbursed loss, cost
or expense which was not applicable, in effect and known to the Issuing Lender
as of the date of this Agreement and which the Issuing Lender in good faith
deems material to it; (ii) one or more of the conditions to such issuance
contained in Section 4.3 is not then satisfied; or (iii) after giving effect to
such issuance, (A) the aggregate amount of the Facility Letter of Credit
Obligations would exceed the Facility Letter of Credit Sublimit, (B) the
Facility B Principal Obligations Amount would exceed the Aggregate Facility B
Commitment, or (C) prior to the Equity Infusion Date, the Principal Obligations
Amount would exceed $16,000,000.

                  (b) In no event shall the expiration date of any Facility
Letter of Credit be later than the earlier of (i) one year from the date of
issuance thereof, and (ii) November 30, 2005.

                  2.18.2 Participating Interests. Immediately upon the issuance
by the Issuing Lender of a Facility Letter of Credit in accordance with Section
2.18.4, each Facility B Lender shall be deemed to have irrevocably and
unconditionally purchased and received from the Issuing Lender, without
recourse, representation or warranty, an undivided participation interest equal
to its Percentage of the face amount of such Facility Letter of Credit and each
draw paid by the Issuing Lender thereunder.

                  2.18.3 Facility Letter of Credit Reimbursement Obligations.
(a) The Borrower agrees to pay to the Issuing Lender (i) on each date that any
amount is drawn under

                                      -24-
<PAGE>   26
each Facility Letter of Credit a sum (and interest on such sum as provided in
clause (ii) below) equal to the amount so drawn plus all other charges and
expenses, if any, with respect thereto specified in the applicable Reimbursement
Agreement and (ii) interest on any and all amounts remaining unpaid under this
Section 2.18.3 until payment in full at the Floating Rate plus 3% per annum.

                  (b) Notwithstanding any provisions to the contrary in any
Reimbursement Agreement, the Borrower agrees to reimburse the Issuing Lender for
amounts which the Issuing Lender pays under such Facility Letter of Credit no
later than the time specified in this Agreement. If the Borrower does not pay
any such Reimbursement Obligations when due, the Borrower shall be deemed to
have immediately requested that the Facility B Lenders make a Floating Rate
Advance under this Agreement in a principal amount equal to such unreimbursed
Reimbursement Obligations. The Agent shall promptly notify the Facility B
Lenders of such deemed request and, without the necessity of compliance with the
requirements of Section 2.8, but subject to satisfaction or waiver of the
conditions precedent set forth in Section 4.3, each Facility B Lender shall make
available to the Agent its Loan in the manner prescribed for Floating Rate
Advances. The proceeds of such Loans shall be paid over by the Agent to the
Issuing Lender for the account of the Borrower in satisfaction of such
unreimbursed Reimbursement Obligations, which shall thereupon be deemed
satisfied by the proceeds of, and replaced by, such Floating Rate Advance.

                  (c) If the Issuing Lender makes a payment on account of any
Facility Letter of Credit and is not concurrently reimbursed therefor by the
Borrower and if for any reason a Floating Rate Advance may not be made pursuant
to paragraph (b) above, then as promptly as practical during normal banking
hours on the date of its receipt of such notice or, if not practicable on such
date, not later than noon (Chicago time) on the Business Day immediately
succeeding such date of notification, each Facility B Lender shall deliver to
the Agent for the account of the Issuing Lender, in immediately available funds,
the purchase price for such Facility B Lender's interest in such unreimbursed
Reimbursement Obligations, which shall be an amount equal to such Facility B
Lender's Percentage of such payment. Each Facility B Lender shall, upon demand
by the Issuing Lender, pay the Issuing Lender interest on such Facility B
Lender's Percentage of such draw from the date of payment by the Issuing Lender
on account of such Facility Letter of Credit until the date of delivery of such
funds to the Issuing Lender by such Facility B Lender at a rate per annum,
computed for actual days elapsed based on a 360-day year, equal to the Federal
Funds Effective Rate for such period; provided, that such payments shall be made
by the Facility B Lenders only in the event and to the extent that the Issuing
Lender is not reimbursed in full by the Borrower for the amount of any draw on
the Facility Letters of Credit.

                  (d) At any time after the Issuing Lender has made a payment on
account of any Facility Letter of Credit and has received from any other
Facility B Lender such Facility B Lender's Percentage of such payment, such
Issuing Lender shall, forthwith upon its receipt of any reimbursement (in whole
or in part) by the Borrower for such payment, or of any other amount from the
Borrower or any other Person in respect of such payment (including, without
limitation, any payment of interest or penalty fees and any payment under any
collateral

                                      -25-
<PAGE>   27
account agreement of the Borrower or any Loan Document but excluding any
transfer of funds from any other Facility B Lender pursuant to Section
2.18.3(b)), transfer to such other Facility B Lender such other Facility B
Lender's Percentage of such reimbursement or other amount; provided, that
interest shall accrue for the benefit of such Facility B Lender from the time
Issuing Lender has made a payment on account of any Facility Letter of Credit;
provided, further, that in the event that the receipt by the Issuing Lender of
such reimbursement or other amount is found to have been a transfer in fraud of
creditors or a preferential payment under the United States Bankruptcy Code or
is otherwise required to be returned, such Facility B Lender shall promptly
return to the Issuing Lender any portion thereof previously transferred by the
Issuing Lender to such Facility B Lender, but without interest to the extent
that interest is not payable by the Issuing Lender in connection therewith.

                  2.18.4 Procedure for Issuance. Prior to the issuance of each
Facility Letter of Credit, and as a condition of such issuance, the Borrower
shall deliver to the Issuing Lender (with a copy to the Agent) a Reimbursement
Agreement signed by the Borrower, together with such other documents or items as
may be required pursuant to the terms thereof, and the proposed form and content
of such Facility Letter of Credit shall be reasonably satisfactory to the
Issuing Lender. Each Facility Letter of Credit shall be issued no earlier than
two Business Days after delivery of the foregoing documents, which delivery may
be by the Borrower to the Issuing Lender by telecopy, telex or other electronic
means followed by delivery of executed originals within five days thereafter.
The documents so delivered shall be in compliance with the requirements set
forth in Section 2.18.1(b), and shall specify therein (i) the stated amount of
the Facility Letter of Credit requested, (ii) the effective date of issuance of
such requested Facility Letter of Credit, which shall be a Business Day, (iii)
the date on which such requested Facility Letter of Credit is to expire, which
shall be a Business Day prior to November 30, 2005, (iv) the entity for whose
benefit the requested Facility Letter of Credit is to be issued, which shall be
the Borrower and (v) the aggregate amount of Facility Letter of Credit
Obligations which are outstanding and which will be outstanding after giving
effect to the requested Facility Letter of Credit issuance. The delivery of the
foregoing documents and information shall constitute an "Issuance Request" for
purposes of this Agreement. Subject to the terms and conditions of Section
2.18.1 and provided that the applicable conditions set forth in Section 4.3 have
been satisfied, the Issuing Lender shall, on the requested date, issue a
Facility Letter of Credit on behalf of the Borrower in accordance with the
Issuing Lender's usual and customary business practices. In addition, any
amendment of an existing Facility Letter of Credit shall be deemed to be an
issuance of a new Facility Letter of Credit and shall be subject to the
requirements set forth above. The Issuing Lender shall give the Agent prompt
written notice of the issuance of any Facility Letter of Credit.

                  2.18.5 Nature of Obligations. (a) The obligations of each
Facility B Lender to make payments to the Agent for the account of the Issuing
Lender with respect to the Facility Letters of Credit shall be irrevocable, not
subject to any qualification or exception whatsoever and shall be made in
accordance with the terms and conditions of this Agreement under all
circumstances, including, without limitation, any of the following
circumstances:

                                      -26-
<PAGE>   28
                           (i) any lack of validity or enforceability of this
Agreement or any of the other Transaction Documents;

                           (ii) the existence of any claim, setoff, defense or
other right which the Borrower may have at any time against the beneficiary of a
Facility Letter of Credit or any transferee of a Facility Letter of Credit (or
any Person for whom any such transferee may be acting), the Agent, the Issuing
Lender, any Facility B Lender or any other Person, whether in connection with
this Agreement, the Facility Letters of Credit, the transactions contemplated
herein or any unrelated transactions (including any underlying transactions
between the Borrower or any Affiliate of the Borrower and the beneficiary of a
Facility Letter of Credit);

                           (iii) any draft, certificate of any other document
presented under a Facility B Letter of Credit proving to be forged, fraudulent
or invalid in any respect, or insufficient in accordance with the Uniform
Customs and Practice for Documentary Credits (1993 revision), International
Chamber of Commerce, Publication 500, or any statement therein being untrue or
inaccurate in any respect;

                           (iv) the surrender or impairment of any security for
the performance or observance of any of the terms of any of the Transaction
Documents; or

                           (v) the occurrence of any Default or Unmatured
Default;

                  provided, however, that the Facility B Lenders shall not be
required to fund their participations in a Facility Letter of Credit if the
corresponding payment made by the Issuing Lender under such Facility B Letter of
Credit was made as a result of the Issuing Lender's gross negligence or willful
misconduct or failure to negotiate a draft in accordance with the standard of
care required by the Uniform Customs and Practice for Documentary Credits (1993
revision), International Chamber of Commerce, Publication 500.

                  (b) The Borrower's obligation to make all payments due under
Section 2.18.3 shall be absolute, unconditional and irrevocable, and such
payments shall be made strictly in accordance with the terms of this Agreement,
under all circumstances whatsoever, including, without limitation, any or all of
the following circumstances:

                           (i) any determination of invalidity or
unenforceability with respect to a Facility Letter of Credit after payment by
the Issuing Lender;

                           (ii) any lack of validity or enforceability of any or
all of the Transaction Documents;

                           (iii) any amendment to, waiver of, any consent under
or departure from any or all of the Transaction Documents;

                           (iv) any exchange, release or nonperfection of any
Collateral, or any release or amendment or waiver of or consent to departure
from any guaranty;

                                      -27-
<PAGE>   29
                           (v) the existence of any claim, setoff, defense or
other right which the Borrower may have at any time against the beneficiary of a
Facility Letter of Credit or any transferee of Facility Letter of Credit (or any
Person for whom any such transferee may be acting), the Agent, the Issuing
Lender, the Facility B Lenders or any other Person; or

                           (vi) any statement or any other document presented
under a Facility Letter of Credit proving to be forged, fraudulent or invalid in
any respect or any statement therein being untrue or inaccurate in any respect
whatsoever.

                  (c) The Issuing Lender shall use its best efforts to give
prompt notice to the Borrower of the presentation of a draft under a Facility
Letter of Credit; provided, however, that failure to give such notice shall not
limit or otherwise affect the Borrower's obligations under this Agreement except
as explicitly provided herein.

                  2.18.6 Indemnification; Assumption of Risk.

                  (a) The Borrower hereby agrees to indemnify and hold harmless
the Agent, the Issuing Lender and each Facility B Lender and their respective
directors, officers and employees from and against any and all claims, damages,
losses, liabilities, costs or expenses of any kind which any thereof may incur
by reason of or in connection with the execution and delivery, issuance or
transfer of, or any payment or failure to pay under, the Facility Letters of
Credit; provided, however, that the Borrower shall not be required to indemnify
the Issuing Lender for any claims, damages, losses, liabilities, costs or
expenses to the extent caused by the gross negligence, willful misconduct, or
failure to negotiate any draft in accordance with the standard of care required
by the Uniform Customs and Practice for Documentary Credits (1993 revision),
International Chamber of Commerce, Publication 500 on the part of the Issuing
Lender in making payment under a Facility Letter of Credit.

                  (b) The Borrower assumes all risks of the acts or omissions of
each beneficiary of a Facility Letter of Credit with respect to its use thereof
or reliance thereon. Neither the Facility B Lenders, the Issuing Lender, nor the
Agent shall be responsible: for the validity or genuineness of certificates or
other documents delivered under or with the Facility Letter of Credit, even if
such certificates or other documents should in fact prove to be invalid,
fraudulent or forged; for errors, omissions, interruptions or delays in
transmission or delivery of any messages, by mail, cable, telegraph, wireless or
otherwise, whether or not they are in code; for errors in translation or for
errors in interpretation of technical terms; for any failure or inability by any
Facility B Lender, the Issuing Lender or the Agent or anyone else to perform
under the foreign laws, customs or regulations or by reason of any control or
restriction rightfully or wrongfully exercised by any government or group
asserting or exercising governmental or paramount powers; or for any other
consequences arising from causes beyond any Facility B Lender's, the Issuing
Lender's or the Agent's control; nor shall any Facility B Lender, the Issuing
Lender, or the Agent be responsible for any error, neglect, or default of any
correspondent of such Person; and none of the above shall affect, impair or
prevent the vesting of any of the rights or powers of any Facility B Lender, the
Issuing Lender or the Agent under any of the Transaction Documents. The Issuing
Lender may accept statements, certificates or other

                                      -28-
<PAGE>   30
documents that appear on their face to be in order, without responsibility for
further investigation, regardless of any notice or information to the contrary.
In furtherance and not in limitation of the foregoing provisions, the Borrower
agrees that any action taken by any Facility B Lender, the Issuing Lender or the
Agent in good faith in connection with the Facility Letters of Credit, or the
relevant drafts, certificates or other documents, shall be binding on the
Borrower and shall not result in any liability of such Facility B Lender, the
Issuing Lender or the Agent to the Borrower. Nothing herein shall limit the
Borrower's right to pursue its remedies against the beneficiary of a Facility
Letter of Credit in connection with any improper or fraudulent draw.

                  2.18.7 Cash Collateral Upon Default. In addition to (and not
in limitation of) any other rights of the Agent and the Lenders under this
Agreement or the Security Agreement, upon the occurrence of a Default, the
Borrower shall upon demand by the Agent immediately deposit with the Agent an
amount equal to the aggregate undrawn face amount of the then outstanding
Facility Letters of Credit.

                  2.18.8 Cash Collateral Account. Any amounts deposited with the
Agent pursuant to Section 2.2.5, 2.2.6, 2.2.7 or 2.18.7 shall be held by the
Agent in a special interest bearing cash collateral account (the "Letter of
Credit Cash Collateral Account") as security for the Borrower's reimbursement
obligations with respect to the Facility Letters of Credit. The Borrower shall
have no control whatsoever over such cash collateral account, which shall be
governed by the provisions of the Security Agreement. The Borrower shall deliver
to the Agent any additional documents, agreements and instruments, and take any
other actions, deemed necessary by the Agent or its counsel to create and
maintain in favor of the Agent on behalf of the Lenders a valid and perfected
Lien on such cash collateral account.

                  2.18.9 Facility Letter of Credit Fees. The Borrower hereby
agrees to pay to the Agent (a) for the account of the Issuing Lender a fee with
respect to each Facility Letter of Credit in an amount equal to 1% of the
initial face amount of such Facility Letter of Credit payable on the date of
issuance, and (b) for the account of the Facility B Lenders, ratably in
proportion to their respective Facility B Commitments, a fee with respect to
each Facility Letter of Credit equal to the Applicable Margin for Eurodollar
Loans times the average daily undrawn face amount thereof, computed on a
quarterly basis and payable quarterly in arrears on each Payment Date and upon
the expiration, cancellation or utilization in full of such Facility Letter of
Credit.

                                   ARTICLE III

                             YIELD PROTECTION; TAXES

         3.1 Yield Protection. If, on or after the date of this Agreement, the
adoption of any law or any governmental or quasi-governmental rule, regulation,
policy, guideline or directive (whether or not having the force of law), or any
change in the interpretation or administration thereof by any governmental or
quasi-governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by any Lender or

                                      -29-
<PAGE>   31
applicable Lending Installation with any request or directive (whether or not
having the force of law) of any such authority, central bank or comparable
agency:

                  (i) subjects any Lender or any applicable Lending Installation
to any Taxes, or changes the basis of taxation of payments (other than with
respect to Excluded Taxes) to any Lender in respect of its Eurodollar Loans or
its interest in the Facility Letters of Credit, or

                  (ii) imposes or increases or deems applicable any reserve,
assessment, insurance charge, special deposit or similar requirement against
assets of, deposits with or for the account of, or credit extended by, any
Lender or any applicable Lending Installation (other than reserves and
assessments taken into account in determining the interest rate applicable to
Eurodollar Advances), or

                  (iii) imposes any other condition the result of which is to
increase the cost to any Lender or any applicable Lending Installation of
making, funding or maintaining its Eurodollar Loans or issuing or participating
in the Facility Letters of Credit or reduces any amount receivable by any Lender
or any applicable Lending Installation in connection with its Eurodollar Loans
or Facility Letters of Credit, or requires any Lender or any applicable Lending
Installation to make any payment calculated by reference to the amount of
Eurodollar Loans held, Facility Letters of Credit issued or participated in or
interest received by it, by an amount deemed material by such Lender,

and the result of any of the foregoing is to increase the cost to such Lender or
applicable Lending Installation of making or maintaining its Eurodollar Loans,
its issuance of or participation in the Facility Letters of Credit, or any
Commitment or to reduce the return received by such Lender or applicable Lending
Installation in connection with such Eurodollar Loans, Facility Letters of
Credit or Commitment, then, within 15 days of demand by such Lender, the
Borrower shall pay such Lender such additional amount or amounts as will
compensate such Lender for such increased cost or reduction in amount received.

         3.2 Changes in Capital Adequacy Regulations. If a Lender determines the
amount of capital required or expected to be maintained by such Lender, any
Lending Installation of such Lender or any corporation controlling such Lender
is increased as a result of a Change, then, within 15 days of demand by such
Lender, the Borrower shall pay such Lender the amount necessary to compensate
for any shortfall in the rate of return on the portion of such increased capital
which such Lender determines is attributable to this Agreement, its Loans, any
Commitment or its issuance of or participation in Facility Letters of Credit
(after taking into account such Lender's policies as to capital adequacy).
"Change" means (i) any change after the date of this Agreement in the Risk-Based
Capital Guidelines or (ii) any adoption of or change in any other law,
governmental or quasi-governmental rule, regulation, policy, guideline,
interpretation, or directive (whether or not having the force of law) after the
date of this Agreement which affects the amount of capital required or expected
to be maintained by any Lender or any Lending Installation or any corporation
controlling any Lender. "Risk-Based Capital Guidelines" means (i) the risk-based
capital guidelines in effect in the United States on the date of this Agreement,
including transition rules, and (ii) the corresponding capital

                                      -30-
<PAGE>   32
regulations promulgated by regulatory authorities outside the United States
implementing the July 1988 report of the Basle Committee on Banking Regulation
and Supervisory Practices Entitled "International Convergence of Capital
Measurements and Capital Standards," including transition rules, and any
amendments to such regulations adopted prior to the date of this Agreement.

         3.3 Availability of Types of Advances. If any Lender determines that
maintenance of its Eurodollar Loans at a suitable Lending Installation would
violate any applicable law, rule, regulation, or directive, whether or not
having the force of law, or if the Required Lenders determine that (i) deposits
of a type and maturity appropriate to match fund Eurodollar Advances are not
available or (ii) the interest rate applicable to a Type of Advance does not
accurately reflect the cost of making or maintaining such Advance, then the
Agent shall suspend the availability of the affected Type of Advance and require
any affected Eurodollar Advances to be repaid or converted to Floating Rate
Advances, subject to the payment of any funding indemnification amounts required
by Section 3.4.

         3.4 Funding Indemnification. If any payment of a Eurodollar Advance
occurs on a date which is not the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise, or a Eurodollar
Advance is not made on the date specified by the Borrower for any reason other
than default by the Lenders, the Borrower will indemnify each Lender for any
loss or cost incurred by it resulting therefrom, including, without limitation,
any loss or cost in liquidating or employing deposits acquired to fund or
maintain such Eurodollar Advance.

         3.5 Taxes. (i) All payments by the Borrower to or for the account of
any Lender or the Agent hereunder or under any Note shall be made free and clear
of and without deduction for any and all Taxes. If the Borrower shall be
required by law to deduct any Taxes from or in respect of any sum payable
hereunder to any Lender or the Agent, (a) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 3.5) such Lender or the
Agent (as the case may be) receives an amount equal to the sum it would have
received had no such deductions been made, (b) the Borrower shall make such
deductions, (c) the Borrower shall pay the full amount deducted to the relevant
authority in accordance with applicable law and (d) the Borrower shall furnish
to the Agent the original or a certified copy of a receipt evidencing payment
thereof.

         (ii) In addition, the Borrower hereby agrees to pay any present or
future stamp or documentary taxes and any other excise or property taxes,
charges or similar levies which arise from any payment made hereunder or under
any Note or from the execution or delivery of, or otherwise with respect to,
this Agreement or any Note ("Other Taxes").

         (iii) The Borrower hereby agrees to indemnify the Agent and each Lender
for the full amount of Taxes or Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed on amounts payable under this Section 3.5) paid by
the Agent or such Lender and any liability (including penalties, interest and
expenses) arising therefrom or with respect thereto.

                                      -31-
<PAGE>   33
Payments due under this indemnification shall be made within 30 days of the date
the Agent or such Lender makes demand therefor pursuant to Section 3.6.

         (iv) At least five Business Days prior to the first date on which
interest is payable hereunder for the account of any Lender, each Lender that is
not incorporated under the laws of the United States of America or a state
thereof (each a "Non-U.S. Lender") agrees that it will deliver to each of the
Borrower and the Agent two duly completed copies of United States Internal
Revenue Service Form 1001 or 4224, certifying in either case that such Lender is
entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes. Each Non-U.S. Lender
further undertakes to deliver to each of the Borrower and the Agent (i) two
renewals or additional copies of such form (or any successor form) on or before
the date that such form expires or becomes obsolete, and (ii) after the
occurrence of any event requiring a change in the most recent forms so delivered
by it, such additional forms or amendments thereto as may be reasonably
requested by the Borrower or the Agent. All forms or amendments described in the
preceding sentence shall certify that such Lender is entitled to receive
payments under this Agreement without deduction or withholding of any United
States federal income taxes, unless an event (including without limitation any
change in treaty, law or regulation) has occurred prior to the date on which any
such delivery would otherwise be required which renders all such forms
inapplicable or which would prevent such Lender from duly completing and
delivering any such form or amendment with respect to it and such Lender advises
the Borrower and the Agent that it is not capable of receiving payments without
any deduction or withholding of United States federal income tax.

         (v) For any period during which a Non-U.S. Lender has failed to provide
the Borrower with an appropriate form pursuant to clause (iv), above (unless
such failure is due to a change in treaty, law or regulation, or any change in
the interpretation or administration thereof by any governmental authority,
occurring subsequent to the date on which a form originally was required to be
provided), such Non-U.S. Lender shall not be entitled to indemnification under
this Section 3.5 with respect to Taxes imposed by the United States; provided
that, should a Non-U.S. Lender which is otherwise exempt from or subject to a
reduced rate of withholding tax become subject to Taxes because of its failure
to deliver a form required under clause (iv), above, the Borrower shall take
such steps as such Non-U.S. Lender shall reasonably request to assist such
Non-U.S. Lender to recover such Taxes.

         3.6 Lender Statements; Survival of Indemnity. To the extent reasonably
possible, each Lender shall designate an alternate Lending Installation with
respect to its Eurodollar Loans to reduce any liability of the Borrower to such
Lender under Sections 3.1, 3.2, and 3.5 or to avoid the unavailability of
Eurodollar Advances under Section 3.3, so long as such designation is not, in
the reasonable judgment of such Lender, disadvantageous to such Lender. Each
Lender shall deliver a written statement of such Lender to the Borrower (with a
copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4, or
3.5. Such written statement shall set forth in reasonable detail the
calculations upon which such Lender determined such amount and shall be final,
conclusive and binding on the Borrower in the absence of manifest error.
Determination of amounts payable under such Sections in connection with a
Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar
Loan through the purchase of a

                                      -32-
<PAGE>   34
deposit of the type and maturity corresponding to the deposit used as a
reference in determining the Eurodollar Rate applicable to such Loan, whether in
fact that is the case or not. Unless otherwise provided herein, the amount
specified in the written statement of any Lender shall be payable on demand
after receipt by the Borrower of such written statement. The obligations of the
Borrower under Sections 3.1, 3.2, 3.4, and 3.5 shall survive payment of the
Obligations and termination of this Agreement.

                                   ARTICLE IV

         4.2 Certain Advances. Prior to January 1, 2001, the Lenders shall not
be required to make any Advance under Facility B that would cause the Facility B
Principal Obligations Amount to exceed $8,000,000 (other than an Advance that,

         The Borrower represents and warrants to the Lenders that:


                                     - 35 -
<PAGE>   37
         5.1 Corporate Existence and Standing. The Borrower and each of its
Subsidiaries is a corporation duly incorporated, validly existing and in good
standing under the laws of its jurisdiction of incorporation and has all
requisite authority to conduct its business in each jurisdiction in which its
business is conducted.

         5.2 Authorization and Validity. The Borrower has the corporate power
and authority and legal right to execute and deliver the Loan Documents and to
perform its obligations thereunder. The execution and delivery by the Borrower
of the Loan Documents and the performance of its obligations thereunder have
been duly authorized by proper corporate proceedings, and the Loan Documents
constitute legal, valid and binding obligations of the Borrower enforceable
against the Borrower in accordance with their terms, except as enforceability
may be limited by bankruptcy, insolvency or similar laws affecting the
enforcement of creditors' rights generally.

         5.3 No Conflict; Government Consent. Neither the execution and delivery
by the Borrower of the Loan Documents, nor the consummation of the transactions
therein contemplated, nor compliance with the provisions thereof will (a) to the
Borrower's knowledge, violate any law, rule, regulation, order, writ, judgment,
injunction, decree or award binding on the Borrower or any of its Subsidiaries
or (b) violate the Borrower's or any Subsidiary's articles of incorporation or
by-laws or the provisions of any indenture, instrument or agreement to which the
Borrower or any of its Subsidiaries is a party or is subject, or by which it, or
its Property, is bound, or conflict with or constitute a default thereunder, or
(c) result in the creation or imposition of any Lien in, of or on the Property
of the Borrower or a Subsidiary pursuant to the terms of any such indenture,
instrument or agreement (other than the Lien created by the Security Agreement).
No material order, consent, approval, license, authorization, or validation of,
or filing, recording or registration with, or exemption by, any governmental or
public body or authority, or any subdivision thereof, which has not been
obtained by the Borrower or any of its Subsidiaries, is required to be obtained
by the Borrower or any of its Subsidiaries in connection with the execution,
delivery and performance of, or the legality, validity, binding effect or
enforceability of, any of the Loan Documents.

         5.4 Financial Statements. The December 31, 1998 and June 30, 1999
consolidated financial statements of the Borrower and its Subsidiaries
heretofore delivered to the Lenders were prepared in accordance with generally
accepted accounting principles in effect on the date such statements were
prepared and fairly present the consolidated financial condition and operations
of the Borrower and its Subsidiaries at such date and the consolidated results
of their operations for the period then ended.

         5.5 Material Adverse Change. Since March 31, 1999, there has been no
change in the business, Property, prospects, condition (financial or otherwise)
or results of operations of the Borrower and its Subsidiaries which could
reasonably be expected to have a Material Adverse Effect.

         5.6 Taxes. The Borrower and its Subsidiaries have filed all United
States federal tax returns and all other tax returns which are required to be
filed and have paid all taxes due


                                     - 36 -
<PAGE>   38
pursuant to said returns or pursuant to any assessment received by the Borrower
or any of its Subsidiaries, except such taxes, if any, as are being contested in
good faith and as to which adequate reserves have been provided in accordance
with Agreement Accounting Principles and as to which no Lien exists. The United
States income tax returns of the Borrowers and their Subsidiaries have been
audited by the Internal Revenue Service through the fiscal year ended December
31, 1992. No tax liens have been filed and no claims are being asserted with
respect to any such taxes. The charges, accruals and reserves on the books of
the Borrower and its Subsidiaries in respect of any taxes or other governmental
charges are adequate.

         5.7 Litigation and Contingent Obligations. Except as set forth on
Schedule "4" hereto, there is no (i) litigation or arbitration pending, (ii)
governmental investigation, proceeding or inquiry of which the Borrower has
received notice pending, or (iii) to the knowledge of any of its officers,
litigation, arbitration, governmental investigation, proceeding or inquiry
threatened against or affecting the Borrower or any of its Subsidiaries, which
could reasonably be expected to have a Material Adverse Effect or which seeks to
prevent, enjoin or delay the making of the Advances or the issuance of the
Facility Letters of Credit. Other than any liability incident to such
litigation, arbitration or proceedings, the Borrower has no material contingent
obligations not provided for or disclosed in the financial statements referred
to in Section 5.4.

         5.8 Subsidiaries. Schedule "2" hereto contains an accurate list of all
Subsidiaries of the Borrower, setting forth their respective jurisdictions of
incorporation and the percentage of their respective capital stock owned by the
Borrower or other Subsidiaries. All of the issued and outstanding shares of
capital stock of such Subsidiaries have been duly authorized and issued and are
fully paid and non-assessable.

         5.9 ERISA. The Borrower has no Unfunded Liabilities. Neither the
Borrower nor any other member of the Controlled Group has incurred, or is
reasonably expected to incur, any withdrawal liability to Multiemployer Plans.
Each Plan complies in all material respects with all applicable requirements of
law and regulations, no Reportable Event has occurred with respect to any Plan,
neither the Borrower nor any other member of the Controlled Group has withdrawn
from any Plan or initiated steps to do so, and no steps have been taken to
reorganize or terminate any Plan.

         5.10 Accuracy of Information. No information, exhibit or report
furnished by the Borrower or any of its Subsidiaries to the Agent or to any
Lender in connection with the negotiation of, or compliance with, the Loan
Documents contained any material misstatement of fact or omitted to state a
material fact or any fact necessary to make the statements contained therein not
misleading. The projections and pro forma determinations delivered to the Agent
and the Lenders are reasonable and are based on reasonable assumptions of the

         5.12 Material Agreements. Neither the Borrower nor any Subsidiary is a
party to any agreement or instrument or subject to any charter or other
corporate restriction which could reasonably be expected to have a Material
Adverse Effect. Neither the Borrower nor any Subsidiary is in default in the
performance, observance or fulfillment of any of the obligations, covenants or
conditions contained in (i) any agreement to which it is a party, which default
could reasonably be expected to have a Material Adverse Effect or (ii) any
agreement or instrument evidencing or governing Material Indebtedness.

         5.13 Compliance With Laws, Etc. The Borrower and its Subsidiaries have
materially complied with all applicable statutes, rules, regulations, orders and
restrictions of any domestic or foreign government or any instrumentality or
agency thereof, having jurisdiction over the conduct of their respective
businesses or the ownership of their respective Property. The Borrower and the
Subsidiaries have obtained all material franchises, licenses, consents,
approvals and authorizations granted or issued by any public or governmental
body, agency or authority necessary and appropriate to operate their respective
businesses and all such franchises, licenses, certificates, consents, approvals
and authorizations are in full force and effect.

         5.14 Ownership of Properties. Except as set forth on Schedule "3"
hereto, on the date of this Agreement, the Borrower and its Subsidiaries will
have good title, free of all Liens other than those permitted by Section 6.18,
to all of the Property and assets reflected in the financial statements as owned
by it.

         5.15 Plan Assets; Prohibited Transactions. The Borrower is not an
entity deemed to hold "plan assets" within the meaning of 29 C.F.R. Section
2510.3-101 of an employee benefit plan (as defined in Section 3(3) of ERISA)
which is subject to Title I of ERISA or any plan (within the meaning of Section
4975 of the Code); neither the execution of this Agreement nor the making of
Loans or issuance of Facility Letters of Credit hereunder gives rise to a
prohibited transaction within the meaning of Section 406 of ERISA or Section
4975 of the Code; and "benefit plan investors" (as defined in 29 C.F.R. Section
2510.3-101(f)) do not own 25% or more of the value of any class of equity
interests in the Borrower.

         5.16 Environmental Matters. In the ordinary course of its business, the
officers of the Borrower consider the effect of Environmental Laws on the
business of the Borrower and its Subsidiaries, in the course of which they
identify and evaluate potential risks and liabilities accruing to the Borrower
due to Environmental Laws. On the basis of this consideration, the Borrower has
concluded that Environmental Laws cannot reasonably be expected to have a
Material Adverse Effect. Neither the Borrower nor any Subsidiary has received
any notice to the effect that its operations are not in material compliance with
any of the requirements of applicable Environmental Laws or the subject of any
federal or state investigation evaluating whether any remedial action is needed
to respond to a release of any toxic or hazardous waste or substance into the
environment, which non-compliance or remedial action could reasonably be
expected to have a Material Adverse Effect.

         5.17 Investment Company Act. Neither the Borrower nor any Subsidiary is
an "investment company" or a company "controlled" by an "investment company,"
within the meaning of the Investment Company Act of 1940, as amended.

         5.18 Public Utility Holding Company Act. Neither the Borrower nor any
Subsidiary is a "holding company" or a "subsidiary company" of a "holding
company", or an "affiliate" of a "holding company" or of a "subsidiary company"
of a "holding company", within the meaning of the Public Utility Holding Company
Act of 1935, as amended.

         5.19 Solvency. (i) Immediately after the consummation of the
transactions to occur on the Effective Date and immediately following the making
of each Loan and after giving effect to the application of the proceeds of such
Loans, (a) the fair value of the assets of the Borrower and its Subsidiaries on
a consolidated basis, at a fair valuation, will exceed the debts and
liabilities, subordinated, contingent or otherwise, of the Borrower and its
Subsidiaries on a consolidated basis; (b) the present fair saleable value of the
property of the Borrower and its Subsidiaries on a consolidated basis will be
greater than the amount that will be required to pay the probable liability of
the Borrower and its Subsidiaries on a consolidated basis on their debts and
other liabilities, subordinated, contingent or otherwise, as such debts and
other liabilities become absolute and matured; (c) the Borrower and its
Subsidiaries on a consolidated basis will be able to pay their debts and
liabilities, subordinated, contingent or otherwise, as such debts and
liabilities become absolute and matured; and (d) the Borrower and its
Subsidiaries on a consolidated basis will not have unreasonably small capital
with which to conduct the businesses in which they are engaged as such
businesses are now conducted and are proposed to be conducted after the date
hereof.

         (ii) The Borrower does not intend to, or to permit any of its
Subsidiaries to, and does not believe that it or any of its Subsidiaries will,
incur debts beyond its ability to pay such debts as they mature, taking into
account the timing of and amounts of cash to be received by it or any such
Subsidiary and the timing of the amounts of cash to be payable on or in respect
of its Indebtedness or the Indebtedness of any such Subsidiary.

         5.20 Year 2000. The Borrower has made a full and complete assessment of
the Year 2000 Issues and has a realistic and achievable program for remediating
the Year 2000 Issues on a timely basis (the "Year 2000 Program"). Based on such
assessment and on the Year 2000 Program the Borrower does not reasonably
anticipate that Year 2000 Issues will have a Material Adverse Effect.

together with any updates or progress reports with respect thereto.

         6.24 Collateral Security; Further Assurances.

                  6.24.1 Grant of Security. As security for the payment of the

in all of the following, whether now or hereafter existing or acquired: (i) all
of the outstanding stock of the Borrower and all proceeds thereof, all as more
specifically described in the Pledge Agreement; and (ii) all of the outstanding
equity interests in any Subsidiary and all proceeds thereof, and all other
assets of the Borrower (other than real estate) and all proceeds thereof, all as
more specifically described in and subject to the provisions of the Security
Agreement.

                  6.24.2 Subsidiaries. The Borrower shall cause the Secured
Obligations to be and remain guaranteed in writing by each Subsidiary pursuant
to a guaranty in form and substance satisfactory to the Required Lenders. As
security for the payment of any Subsidiary's guaranty of the Secured
Obligations, the Borrower shall cause such Subsidiary to grant to the Agent on
behalf of the Lenders a Lien on and security interest in all of the assets of
such Subsidiary (other than real estate and interests therein), whether now or
hereafter existing or acquired, and all proceeds thereof, all as more
specifically described in and subject to the provisions of a security agreement
substantially identical to the Security Agreement with appropriate adjustments
for such Subsidiary. Upon execution of a guaranty and a security agreement by
any Subsidiary created or acquired (in accordance with the terms of this
Agreement) after the date of this Agreement, the Borrower shall also cause to be
delivered to the Agent such items evidencing legal existence, validity, power,
and authorization (including, without limitation, an opinion of counsel)
comparable to the items required with respect to Holdings pursuant to Section
4.1 as the Agent may reasonably require.

                  6.24.3 Additional Collateral; Further Assurances. At the
request of the Required Lenders, the Borrower shall, and shall cause such
Subsidiary to, execute and deliver to the Agent any additional documents,
agreements and instruments, including, without limitation, collateral
assignments of leases and leasehold mortgages, UCC-1 financing statements and
fixture filings, and take any other actions, deemed necessary by the Agent or
its counsel to create and maintain in favor of the Agent on behalf of the
Lenders a valid and perfected Lien on collateral purported to be covered by the
Security Agreement or any security agreement executed and delivered by a
Subsidiary pursuant to Section 6.24.2 and/or any additional assets of the


                                     - 50 -
<PAGE>   52
Borrower or any Subsidiary, including, without limitation, ground leases and
vehicles covered by certificates of title.

                  6.24.4 Negative Pledge Prohibition. The Borrower shall not,
and shall not permit any Subsidiary to, enter into an agreement with any other
Person that would prohibit it from complying with the provisions of Section
6.24.3 or pursuant to which a breach would occur or a Lien would be created or
imposed by virtue of such compliance.

                  6.24.5 Exercise of Rights. In connection with any exercise by
the Agent or any Lender of its right and remedies under the Collateral
Documents, it may be necessary to obtain the prior consent or approval of
certain Persons, including but not limited to applicable governmental
authorities. Upon the exercise by the Agent or the Lenders of any power, right,
privilege or remedy pursuant to any Collateral Document which requires any
consent, approval, registration, qualification or authorization of any Person,
the Borrower will execute and deliver, or will cause the execution and delivery
of, all applications, certificates, instruments, and other documents and papers
that the Agent or the Lenders may be required to obtain for such consent,
approval, registration, qualification or authorization. Without limiting the
generality of the foregoing, the Borrower will use its best efforts to obtain
from the appropriate Persons the necessary consents and approvals, if any, for
the effectuation of any sale or sales of pledged interests upon the occurrence
and during the continuance of a Default; and for the exercise of any other right
or remedy of the Agent and Lenders under any Collateral Document. The Agent and
the Lenders will cooperate with the Borrower in preparing the filing with any
Persons of all requisite applications required to be obtained by the Borrower
under this Section 6.24.5.

         6.25 Senior Notes. The Borrower will not, and will not permit any
Subsidiary to, directly or indirectly voluntarily prepay, defease or in
substance defease, purchase, redeem, retire or otherwise acquire, any Senior
Notes, or make any amendment or modification to the Senior Note Indenture that
is materially adverse to the Lenders.

                                    DEFAULTS

provisions of this Agreement which is not remedied within fifteen days after
written notice from the Agent or any Lender; provided, however, that if such
Default is susceptible of cure but cannot reasonably be cured within such
fifteen-day period, and the Borrower shall have commenced to cure such Default
within such fifteen-day period and thereafter diligently and expeditiously
proceeds to cure the same, such fifteen-day period shall be extended for an
additional period of time as is reasonably necessary for the Borrower in the
exercise of due diligence to cure such Default, such additional period not to
exceed thirty days.

any of the Subsidiaries in the performance of any term, provision or condition
contained in any agreement under which any Material Indebtedness was created or
is governed, or any other event shall occur or condition exist, the effect of

Indebtedness to cause, such Material Indebtedness to become due prior to its
stated maturity; or any Material Indebtedness of Holdings, the Borrower or any
of the Subsidiaries shall be declared to be due and payable or required to be
prepaid or repurchased (other than by a regularly scheduled payment) prior to
the stated maturity thereof; or Holdings, the Borrower or any of the
Subsidiaries shall not pay, or admit in writing its inability to pay, its debts

creditors, (iii) apply for, seek, consent to, or acquiesce in, the appointment
of a receiver, custodian, trustee, examiner, liquidator or similar official for
it or any of its Property which constitutes a Substantial Portion, (iv)
institute any proceeding seeking an order for relief under the Federal
bankruptcy laws as now or hereafter in effect or seeking to adjudicate it a
bankrupt or insolvent, or seeking dissolution, winding up, liquidation,
reorganization, arrangement, adjustment or composition of it or its debts under
any law relating to bankruptcy, insolvency or reorganization or relief of
debtors or fail to file an answer or other pleading denying the material
allegations of any such proceeding filed against it, (v) take any corporate

termination the aggregate annual contributions of the Borrower and the other
members of the Controlled Group (taken as a whole) to all Multiemployer Plans
which are then in reorganization or being terminated have been or will be

         7.13 The Borrower or any of its Subsidiaries shall be the subject of
any proceeding or investigation pertaining to the release by the Borrower or any

valid and perfected first priority security interest in any collateral purported

Document and except with regard to ground leases and vehicles covered by
certificates of title to the extent that the Required Lenders have elected not

assert the invalidity or unenforceability of any such Transaction Document.

                                  ARTICLE VIII

                 ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES

         8.1 Acceleration. If any Default described in Section 7.6 or 7.7 occurs
with respect to the Borrower, the obligations of the Lenders to make Loans and
of the Issuing Lender to issue Facility Letters of Credit hereunder shall
automatically terminate and the Obligations shall immediately become due and
payable without any election or action on the part of the Agent or any Lender.
If any other Default occurs, the Required Lenders (or the Agent at the direction
of the Required Lenders) may terminate or suspend the obligations of the Lenders
to make Loans and of the Issuing Lender to issue Facility Letters of Credit
hereunder, or declare the Obligations to be due and payable, or both, whereupon
the Obligations shall become immediately due and payable, without presentment,
demand, protest or notice of any kind, all of which the Borrower hereby
expressly waives.

         If, after acceleration of the maturity of the Obligations or
termination of the obligations of the Lenders to make Loans and of the Issuing
Lender to issue Facility Letters of Credit hereunder as a result of any Default
(other than any Default as described in Section 7.6 or 7.7 with respect to the
Borrower) and before any judgment or decree for the payment of the Obligations
due shall have been obtained or entered, the Required Lenders (in their sole


                                     - 54 -
<PAGE>   56
discretion) shall so direct, the Agent shall, by notice to the Borrower, rescind
and annul such acceleration and/or termination.

         8.2 Amendments. Subject to the provisions of this Article VIII, the
Required Lenders (or the Agent with the consent in writing of the Required
Lenders) and the Borrower may enter into agreements supplemental hereto for the
purpose of adding or modifying any provisions to the Transaction Documents or
changing in any manner the rights of the Lenders or the Borrower hereunder or
waiving any Default hereunder; provided, however, that no such supplemental
agreement shall, without the consent of each Lender affected thereby:

                  (i) Extend the Facility Termination Date or the final maturity
of any Loan or Note or the due date of a Reimbursement Obligation or forgive all
or any portion of the principal amount thereof, or reduce the rate or extend the
time of payment of interest or fees thereon.

                  (ii) Permit any Facility Letter of Credit to expire after
November 30, 2005.

                  (iii) Reduce the percentage specified in the definition of
Required Lenders.

                  (iv) Reduce the amount of, or extend the payment dates for,
the mandatory payments required under Section 2.2, or increase the amount of the
Commitment of any Lender hereunder, or permit the Borrower to assign its rights
under this Agreement.

                  (v) Reduce the amount or extend the time of any mandatory
reduction of the Aggregate Facility B Commitment required by Section 2.5.2.

                  (vi) Amend this Section 8.2.

                  (vii) Except as provided in the Collateral Documents, release
all or substantially all of the Collateral.

No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent. The Agent may waive payment
of the fee required under Section 12.3.2 without obtaining the consent of any
other party to this Agreement.

         8.3 Preservation of Rights. No delay or omission of the Lenders or the
Agent to exercise any right under the Transaction Documents shall impair such
right or be construed to be a waiver of any Default or an acquiescence therein,
and the making of a Loan notwithstanding the existence of a Default or the
inability of the Borrower to satisfy the conditions precedent to such Loan shall
not constitute any waiver or acquiescence. Any single or partial exercise of any
such right shall not preclude other or further exercise thereof or the exercise
of any other right, and no waiver, amendment or other variation of the terms,
conditions or provisions of the Transaction Documents whatsoever shall be valid
unless in writing signed by the Lenders required pursuant to Section 8.2, and
then only to the extent in such writing specifically set forth. All remedies
contained in the Transaction Documents or by law afforded shall be cumulative
and all shall be available to the Agent and the Lenders until the Obligations
have been paid in full.

                                   ARTICLE IX

                               GENERAL PROVISIONS

         9.1 Survival of Representations. All representations and warranties of
the Borrower contained in this Agreement shall survive delivery of any Notes,
the making of the Loans and the issuance of Facility Letters of Credit.

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

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

         9.4 Entire Agreement. The Transaction Documents embody the entire
agreement and understanding among the Borrower, Holdings, the Agent and the
Lenders and supersede all prior agreements and understandings among the
Borrower, Holdings, the Agent and the Lenders relating to the subject matter
thereof, other than the Fee Letter and the Original Fee Letter.

         9.5 Several Obligations; Benefits of this Agreement. The respective
obligations of the Lenders hereunder are several and not joint and no Lender
shall be the partner or agent of any other (except to the extent to which the
Agent is authorized to act as such). The failure of any Lender to perform any of
its obligations hereunder shall not relieve any other Lender from any of its
obligations hereunder. This Agreement shall not be construed so as to confer any
right or benefit upon any Person other than the parties to this Agreement and
their respective successors and assigns, provided, however, that the parties
hereto expressly agree that the Arranger shall enjoy the benefits of the
provisions of Sections 9.6, 9.10 and 10.11 to the extent specifically set forth
therein and shall have the right to enforce such provisions on its own behalf
and in its own name to the same extent as if it were a party to this Agreement.

         9.6 Expenses; Indemnification. The Borrower shall reimburse the Agent
and the Arranger for any costs, internal charges and out-of-pocket expenses
(including attorneys' fees and time charges of attorneys for the Agent, which
attorneys may be employees of the Agent) paid or incurred by the Agent or the
Arranger in connection with the preparation, negotiation, execution, delivery,
syndication, review, amendment, modification, and administration of the
Transaction Documents. The Borrower also agrees to reimburse the Agent, the
Arranger and the Lenders for any costs, internal charges and out-of-pocket
expenses (including attorneys' fees and time charges of attorneys for the Agent,
the Arranger and the Lenders, which attorneys may be employees of the Agent or
the Lenders) paid or incurred by the Agent, the Arranger or any Lender in
connection with the collection and enforcement of the Transaction Documents. The
Borrower further agrees to indemnify the Agent, the Arranger and each Lender,
their respective directors, officers and employees against all losses, claims,
damages, penalties, judgments, liabilities and expenses (including, without
limitation, all expenses of litigation or preparation


                                     - 56 -
<PAGE>   58
therefor whether or not the Agent, the Arranger or any Lender is a party
thereto) which any of them may pay or incur arising out of or relating to this
Agreement, the other Transaction Documents, the transactions contemplated hereby
or the direct or indirect application or proposed application of the proceeds of
any Loan or the use of any Facility Letter of Credit except to the extent they
are determined by a court of competent jurisdiction by final and non-appealable
judgment to have resulted from the gross negligence or willful misconduct of the
party seeking indemnification. The obligations of the Borrower under this
Section 9.6 shall survive the termination of this Agreement.

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

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

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

         9.10 Nonliability of Lenders. The relationship between the Borrower and
the Lenders and the Agent shall be solely that of borrower and lender. Neither
the Agent nor any Lender shall have any fiduciary responsibilities to the
Borrower. Neither the Agent nor any Lender undertakes any responsibility to the
Borrower to review or inform the Borrower of any matter in connection with any
phase of the Borrower's business or operations. The Borrower agrees that neither
the Agent, the Arranger nor any Lender shall have liability to the Borrower
(whether sounding in tort, contract or otherwise) for losses suffered by the
Borrower in connection with, arising out of, or in any way related to, the
transactions contemplated and the relationship established by the Transaction
Documents, or any act, omission or event occurring in connection therewith,
unless it is determined in a final non-appealable judgment by a court of
competent jurisdiction that such losses resulted from the gross negligence or
willful misconduct of the party from which recovery is sought. Neither the
Agent, the Arranger nor any Lender shall have any liability with respect to, and
the Borrower hereby waives, releases and agrees not to sue for, any special,
indirect or consequential damages (but not actual damages) suffered by the
Borrower in connection with, arising out of, or in any way related to the
Transaction Documents or the transactions contemplated thereby.

         9.11 Confidentiality. Each Lender agrees to hold any confidential
information which it may receive from the Borrower pursuant to this Agreement in
confidence, except for disclosure (i) to other Lenders and their respective
Affiliates, (ii) to legal counsel, accountants, and other professional advisors
to that Lender or to a Transferee, (iii) to regulatory officials, (iv) to any
Person as requested pursuant to or as required by law, regulation, or legal
process, (v) to any


                                     - 57 -
<PAGE>   59
Person in connection with any legal proceeding to which that Lender is a party,
(vi) permitted by Section 12.4, and (vii) of information which has become public
through no fault of that Lender.

         9.12 Nonreliance. Each Lender hereby represents that it is not relying
on or looking to any margin stock (as defined in Regulation U) for the repayment
of the Loans provided for herein.

         9.13 Effect of Restatement. This Agreement shall supersede the Existing
Credit Agreement from and after the Effective Date with respect to the
transactions hereunder and with respect to the loans outstanding under the
Existing Credit Agreement as of the Effective Date. The parties hereto
acknowledge and agree, however, that (i) this Agreement and all other
Transaction Documents executed and delivered herewith do not constitute a
novation, payment and reborrowing or termination of the Obligations under the
Existing Credit Agreement and the other Transaction Documents as in effect prior
to the Effective Date, (ii) such Obligations are in all respects continuing with
only the terms being modified as provided in this Agreement and the other
Transaction Documents, and (iii) the liens and security interests in favor of
the Agent for the benefit of the Lenders securing payment of such Obligations
are in all respects continuing and in full force and effect with respect to all
Obligations.

         9.14 Holdings Warrants. On the Effective Date, First Chicago shall
return to Holdings the Warrant, dated as of March 31, 1999, issued by Holdings
to First Chicago in connection with the Existing Credit Agreement.

                                   ARTICLE X

                                    THE AGENT

         10.1 Appointment; Nature of Relationship. The First National Bank of
Chicago is hereby appointed by each of the Lenders as its contractual
representative (herein referred to as the "Agent") hereunder and under each
other Transaction Document, and each of the Lenders irrevocably authorizes the
Agent to act as the contractual representative of such Lender with the rights
and duties expressly set forth herein and in the other Transaction Documents.
The Agent agrees to act as such contractual representative upon the express
conditions contained in this Article X. Notwithstanding the use of the defined
term "Agent," it is expressly understood and agreed that the Agent shall not
have any fiduciary responsibilities to any Lender by reason of this Agreement or
any other Transaction Document and that the Agent is merely acting as the
contractual representative of the Lenders with only those duties as are
expressly set forth in this Agreement and the other Transaction Documents. In
its capacity as the Lenders' contractual representative, the Agent (i) does not
hereby assume any fiduciary duties to any of the Lenders, (ii) is a
"representative" of the Lenders within the meaning of Section 9-105 of the
Uniform Commercial Code and (iii) is acting as an independent contractor, the
rights and duties of which are limited to those expressly set forth in this
Agreement and the other Transaction Documents. Each of the Lenders hereby agrees
to assert no claim against the Agent on any agency theory or any other theory of
liability for breach of fiduciary duty, all of which claims each Lender hereby
waives.


                                     - 58 -
<PAGE>   60
         10.2 Powers. The Agent shall have and may exercise such powers under
the Transaction Documents as are specifically delegated to the Agent by the
terms of each thereof, together with such powers as are reasonably incidental
thereto. The Agent shall have no implied duties to the Lenders, or any
obligation to the Lenders to take any action thereunder except any action
specifically provided by the Transaction Documents to be taken by the Agent.

         10.3 General Immunity. Neither the Agent nor any of its directors,
officers, agents or employees shall be liable to the Borrower, the Lenders or
any Lender for any action taken or omitted to be taken by it or them hereunder
or under any other Transaction Document or in connection herewith or therewith
except for its or their own gross negligence or willful misconduct.

         10.4 No Responsibility for Loans, Recitals, etc. Neither the Agent nor
any of its directors, officers, agents or employees shall be responsible for or
have any duty to ascertain, inquire into, or verify (i) any statement, warranty
or representation made in connection with any Transaction Document or any
borrowing hereunder; (ii) the performance or observance of any of the covenants
or agreements of any obligor under any Transaction Document, including, without
limitation, any agreement by an obligor to furnish information directly to each
Lender; (iii) the satisfaction of any condition specified in Article IV, except
receipt of items required to be delivered solely to the Agent; (iv) the
existence or possible existence of any Default or Unmatured Default, (v) the
validity, effectiveness or genuineness of any Transaction Document or any other
instrument or writing furnished in connection therewith; (vi) the value,
sufficiency, creation, perfection or priority of any interest in any collateral
security; or (vii) the financial condition of the Borrower or any guarantor of
any of the Obligations or of any of the Borrower's or any such guarantor's
respective Subsidiaries. The Agent shall have no duty to disclose to the Lenders
information that is not required to be furnished by the Borrower to the Agent at
such time, but is voluntarily furnished by the Borrower to the Agent (either in
its capacity as Agent or in its individual capacity).

         10.5 Action on Instructions of Lenders. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, hereunder and under any
other Transaction Document in accordance with written instructions signed by the
Required Lenders (or, if required by Section 8.2, each Lender affected thereby),
and such instructions and any action taken or failure to act pursuant thereto
shall be binding on all of the Lenders. The Agent shall be fully justified in
failing or refusing to take any action hereunder and under any other Transaction
Document unless it shall first be indemnified to its satisfaction by the Lenders
pro rata against any and all liability, cost and expense that it may incur by
reason of taking or continuing to take any such action. The Lenders hereby
acknowledge that the Agent shall be under no duty to take any discretionary
action permitted to be taken by it pursuant to the provisions of this Agreement
unless it shall be requested in writing to do so by the Required Lenders.

         10.6 Employment of Agents and Counsel. The Agent may execute any of its
duties as Agent hereunder and under any other Transaction Document by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the
Lenders, except as to money or securities received by it or its authorized
agents, for the default or misconduct of any such agents or



                                     - 59 -
<PAGE>   61
attorneys-in-fact selected by it with reasonable care. The Agent shall be
entitled to advice of counsel concerning the contractual arrangement between the
Agent and the Lenders and all matters pertaining to the Agent's duties hereunder
and under any other Transaction Document.

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

         10.8 Agent's Reimbursement and Indemnification. The Lenders agree to
reimburse and indemnify the Agent ratably in proportion to their respective
Commitments (i) for any amounts not reimbursed by the Borrower for which the
Agent is entitled to reimbursement by the Borrower under the Transaction
Documents, (ii) for any other expenses incurred by the Agent on behalf of the
Lenders, in connection with the preparation, execution, delivery, administration
and enforcement of the Transaction Documents (including, without limitation, for
any expenses incurred by the Agent in connection with any dispute between the
Agent and any Lender or between two or more of the Lenders) and (iii) for any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted against the Agent in any way relating to or
arising out of the Transaction Documents or any other document delivered in
connection therewith or the transactions contemplated thereby, (including,
without limitation, for any such amounts incurred by or asserted against the
Agent in connection with any dispute between the Agent and any Lender or between
two or more of the Lenders) or the enforcement of any of the terms thereof or of
any such other documents, provided that no Lender shall be liable for any of the
foregoing to the extent any of the foregoing is found in a final non-appealable
judgment by a court of competent jurisdiction to have resulted from the gross
negligence or willful misconduct of the Agent. The obligations of the Lenders
under this Section 10.8 shall survive payment of the Obligations and termination
of this Agreement.

         10.9 Notice of Default. The Agent shall not be deemed to have knowledge
or notice of the occurrence of any Default or Unmatured Default hereunder unless
the Agent has received written notice from a Lender or the Borrower referring to
this Agreement describing such Default or Unmatured Default and stating that
such notice is a "notice of default". In the event that the Agent receives such
a notice, the Agent shall give prompt notice thereof to the Lenders.

         10.10 Rights as a Lender. In the event the Agent is a Lender, the Agent
shall have the same rights and powers hereunder and under any other Transaction
Document with respect to its Commitments, its Loans and its Percentage of the
Facility Letter of Credit Obligations as any Lender and may exercise the same as
though it were not the Agent, and the term "Lender" or "Lenders" shall, at any
time when the Agent is a Lender, unless the context otherwise indicates, include
the Agent in its individual capacity. The Agent and its Affiliates may accept
deposits from, lend money to, and generally engage in any kind of trust, debt,
equity or other transaction, in addition to those contemplated by this Agreement
or any other Transaction Document, with the Borrower or any of its Subsidiaries
in which the Borrower or such Subsidiary is not restricted


                                     - 60 -
<PAGE>   62
hereby from engaging with any other Person. The Agent, in its individual
capacity, is not obligated to remain a Lender.

         10.11 Lender Credit Decision. Each Lender acknowledges that it has,
independently and without reliance upon the Agent, the Arranger, or any other
Lender and based on the financial statements prepared by the Borrower and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement and the other
Transaction Documents. Each Lender also acknowledges that it will, independently
and without reliance upon the Agent, the Arranger, or any other Lender and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit decisions in taking or not taking action under
this Agreement and the other Transaction Documents.

         10.12 Successor Agent. The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower, such resignation to be
effective upon the appointment of a successor Agent or, if no successor Agent
has been appointed, forty-five days after the retiring Agent gives notice of its
intention to resign. Upon any such resignation, the Required Lenders shall have
the right to appoint, on behalf of the Borrower and the Lenders and with the
consent of the Borrower (which shall not be unreasonably withheld), a successor
Agent. Notwithstanding the previous sentence, the Agent may at any time without
the consent of the Borrower or any Lender, appoint any of its Affiliates which
is a commercial bank as a successor Agent hereunder. If no successor Agent shall
have been so appointed by the Required Lenders within thirty days after the
resigning Agent's giving notice of its intention to resign, then the resigning
Agent may appoint, on behalf of the Borrower and the Lenders, a successor Agent.
If the Agent has resigned and no successor Agent has been appointed, the Lenders
may perform all the duties of the Agent hereunder and the Borrower shall make
all payments in respect of the Obligations to the applicable Lender and for all
other purposes shall deal directly with the Lenders. No successor Agent shall be
deemed to be appointed hereunder until such successor Agent has accepted the
appointment. Any such successor Agent shall be a commercial bank having capital
and retained earnings of at least $100,000,000. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the resigning Agent. Upon the effectiveness of the resignation of
the Agent, the resigning Agent shall be discharged from its duties and
obligations hereunder and under the Transaction Documents. After the
effectiveness of the resignation of an Agent, the provisions of this Article X
shall continue in effect for the benefit of such Agent in respect of any actions
taken or omitted to be taken by it while it was acting as the Agent hereunder
and under the other Transaction Documents. In the event that there is a
successor to the Agent by merger, or the Agent assigns its duties and
obligations to an Affiliate pursuant to this Section 10.12, then the term
"Corporate Base Rate" as used in this Agreement shall mean the prime rate, base
rate or other analogous rate of the new Agent.

         10.13 Delegation to Affiliates. The Borrower and the Lenders agree that
the Agent may delegate any of its duties under this Agreement to any of its
Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents
and employees) which performs duties in connection


                                     - 61 -

with this Agreement shall be entitled to the same benefits of the
indemnification, waiver and other protective provisions to which the Agent is
entitled under Articles IX and X.

         10.14 Execution of Collateral Documents. The Lenders hereby empower and
authorize the Agent to execute and deliver to the Borrower on their behalf (i)
the Security Agreement and all related financing statements and any financing
statements, agreements, documents or instruments as shall be necessary or
appropriate to effect the purposes of the Security Agreement, (ii) the Pledge
Agreement(s) and all related financing statements and any financing statements,
agreements, documents or instruments as shall be necessary or appropriate to
effect the purposes of the Pledge Agreement(s) and (iii) any guarantees and
security agreements executed and delivered by Subsidiaries pursuant to Section

         10.15 Collateral Releases. The Lenders hereby empower and authorize the
Agent to execute and deliver to the Borrower on their behalf any agreements,
documents or instruments as shall be necessary or appropriate to effect any
releases of Collateral which shall be permitted by the terms hereof or of any

Required Lenders (or, if required by the terms of Section 8.2, all of the
Lenders) in writing.

                                   ARTICLE XI

                            SETOFF; RATABLE PAYMENTS

         11.1 Setoff. In addition to, and without limitation of, any rights of
the Lenders under applicable law, if the Borrower becomes insolvent, however
evidenced, or any Default occurs, any and all deposits (including all account
balances, whether provisional or final and whether or not collected or
available) and any other Indebtedness at any time held or owing by any Lender or
any Affiliate of any Lender to or for the credit or account of the Borrower may
be offset and applied toward the payment of the Obligations owing to such
Lender, whether or not the Obligations, or any part hereof, shall then be due.

         11.2 Ratable Payments. If any Lender, whether by setoff or otherwise,
has payment made to it upon its Loans (or, with respect to Facility Letters of
Credit, its Percentage of a Reimbursement Obligation) under either Facility
(other than payments received pursuant to Sections 3.1, 3.2, 3.4, or 3.5) in a
greater proportion than that received by any other Lender under such Facility,
such Lender agrees, promptly upon demand, to purchase a portion of the Loans
(and, with respect to Facility Letters of Credit, Reimbursement Obligations)
held by the other Lenders under such Facility so that after such purchase each
Lender will hold its ratable proportion of Loans (and, with respect to Facility
Letters of Credit, Reimbursement Obligations) under such Facility. If any
Lender, whether in connection with setoff or amounts which might be subject to
setoff or otherwise, receives collateral or other protection for its Obligations
or such amounts which may be subject to setoff, such Lender agrees, promptly
upon demand, to take such action necessary such that all Lenders share in the
benefits of such collateral ratably in proportion to their Loans. In case any
such payment is disturbed by legal process, or otherwise, appropriate further
adjustments shall be made.

                                  ARTICLE XII

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

         12.1 Successors and Assigns. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns, except that (i) the
Borrower shall not have the right to assign its rights or obligations under the
Loan Documents and (ii) any assignment by any Lender must be made in compliance
with Section 12.3. Notwithstanding clause (ii) of this Section, any Lender may
(at no cost to the Borrower) at any time, without the consent of the Borrower or
the Agent, assign all or any portion of its rights under this Agreement and any
Note to a Federal Reserve Bank; provided, however, that no such assignment shall
release the transferor Lender from its obligations hereunder. The Agent may
treat the payee of any Note as the owner thereof for all purposes hereof unless
and until such payee complies with Section 12.3 in the case of an assignment
thereof or, in the case of any other transfer, a written notice of the transfer
is filed with the Agent. Any assignee or transferee of a Note agrees by
acceptance thereof to be bound by all the terms and provisions of the
Transaction Documents. Any request, authority or consent of any Person, who at
the time of making such request or giving such authority or consent is the
holder of any Note, shall be conclusive and binding on any subsequent holder,
transferee or assignee of such Note or of any Note or Notes issued in exchange
therefor.

         12.2 Participations.

                  12.2.1 Permitted Participants; Effect. Any Lender may, in the
ordinary course of its business and in accordance with applicable law, at any
time sell to one or more banks or other entities ("Participants") participating
interests in any Loan owing to such Lender, any Note held by such Lender, any
Commitment or Facility Letter of Credit Obligation of such Lender or any other
interest of such Lender under the Transaction Documents, provided that any such
sale shall be at no cost to the Borrower. In the event of any such sale by a
Lender of participating interests to a Participant, such Lender's obligations
under the Transaction Documents shall remain unchanged, such Lender shall remain
solely responsible to the other parties hereto for the performance of such
obligations, such Lender shall remain the holder of any such Note for all
purposes under the Transaction Documents, all amounts payable by the Borrower
under this Agreement shall be determined as if such Lender had not sold such
participating interests, and the Borrower and the Agent shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under the Transaction Documents.

                  12.2.2 Voting Rights. Each Lender shall retain the sole right
to approve, without the consent of any Participant, any amendment, modification
or waiver of any provision of the Transaction Documents other than any
amendment, modification or waiver with respect to any Loan, Commitment or
Facility Letter of Credit Obligation in which such Participant has an interest
which forgives principal, interest or fees or reduces the interest rate or fees
payable with respect to any such Loan, Commitment or Facility Letter of Credit
Obligation, postpones any date fixed for any regularly-scheduled payment of
principal of, or interest or fees on, any such



                                     - 63 -
<PAGE>   65
Loan, Commitment or Facility Letter of Credit Obligation, releases any guarantor
of any such Loan, Commitment or Facility Letter of Credit Obligation or releases
all or substantially all of the Collateral, if any, securing any such Loan or
Facility Letter of Credit Obligation.

                  12.2.3 Benefit of Setoff. The Borrower agrees that each
Participant shall be deemed to have the right of setoff provided in Section 11.1
in respect of its participating interest in amounts owing under the Transaction
Documents to the same extent as if the amount of its participating interest were
owing directly to it as a Lender under the Transaction Documents, provided that
each Lender shall retain the right of setoff provided in Section 11.1 with
respect to the amount of participating interests sold to each Participant. The
Lenders agree to share with each Participant, and each Participant, by
exercising the right of setoff provided in Section 11.1, agrees to share with
each Lender, any amount received pursuant to the exercise of its right of
setoff, such amounts to be shared in accordance with Section 11.2 as if each
Participant were a Lender.

         12.3 Assignments.

                  12.3.1 Permitted Assignments. Any Lender may, in the ordinary
course of its business and in accordance with applicable law, at any time assign
to one or more banks or other entities ("Purchasers") all or any part of its
rights and obligations under the Transaction Documents, provided that (i) any
such assignment shall be at no cost the Borrower, and (ii) unless such Lender
assigns all of its rights and obligations under the Transaction Documents to a
Purchaser, each such assignment shall be in a minimum amount of $5,000,000. Such
assignment shall be substantially in the form of Exhibit "D" hereto or in such
other form as may be agreed to by the parties thereto. The consents of the
Borrower and the Agent shall be required prior to an assignment becoming
effective with respect to a Purchaser which is not a Lender or an Affiliate
thereof; provided, however, that if a Default has occurred and is continuing,
the consent of the Borrower shall not be required. Such consent shall not be
unreasonably withheld.

                  12.3.2 Effect; Effective Date. Upon (i) delivery to the Agent
of a notice of assignment, substantially in the form attached as Annex "I" to
Exhibit "D" hereto (a "Notice of Assignment"), together with any consents
required by Section 12.3.1, and (ii) payment by the assigning Lender or the
Purchaser of a $4,000 fee to the Agent for processing such assignment by one of
the parties thereto, such assignment shall become effective on the effective
date specified in such Notice of Assignment. The Notice of Assignment shall
contain a representation by the Purchaser to the effect that none of the
consideration used to make the purchase of the Commitment(s), Loans and Facility
Letter of Credit Obligations under the applicable assignment agreement are "plan
assets" as defined under ERISA and that the rights and interests of the
Purchaser in and under the Loan Documents will not be "plan assets" under ERISA.
On and after the effective date of such assignment, such Purchaser shall for all
purposes be a Lender party to this Agreement and any other Transaction Document
executed by or on behalf of the Lenders and shall have all the rights and
obligations of a Lender under the Transaction Documents, to the same extent as
if it were an original party hereto, and no further consent or action by the
Borrower, the Lenders or the Agent shall be required to release the transferor
Lender with respect to the percentage of the applicable Aggregate Commitment and


                                     - 64 -
<PAGE>   66
Loans (and, if applicable, Facility Letter of Credit Obligations) assigned to
such Purchaser. Upon the consummation of any assignment to a Purchaser pursuant
to this Section 12.3.2, the transferor Lender, the Agent and the Borrower shall,
if the transferor Lender or the Purchaser desires that its Loans be evidenced by
Notes, make appropriate arrangements so that new Notes or, as appropriate,
replacement Notes are issued to such transferor Lender and new Notes or, as
appropriate, replacement Notes, are issued to such Purchaser, in each case in
principal amounts reflecting their applicable Commitment, as adjusted pursuant
to such assignment. Within a reasonable time after the effective date of any
assignment, the Agent shall, and is hereby authorized and directed to, revise
Schedule "1" reflecting the revised Commitments of each of the Lenders. Such
revised Schedule "1" shall replace the prior Schedule "1" and become part of
this Agreement.

         12.4 Dissemination of Information. The Borrower authorizes each Lender
to disclose to any Participant or Purchaser or any other Person acquiring an
interest in the Transaction Documents by operation of law (each a "Transferee")
and any prospective Transferee any and all information in such Lender's
possession concerning the creditworthiness of the Borrower and its Subsidiaries,
provided that each Transferee and prospective Transferee agrees to be bound by
Section 9.11 of this Agreement.

         12.5 Tax Treatment. If any interest in any Transaction Document is
transferred to any Transferee which is organized under the laws of any
jurisdiction other than the United States or any State thereof, the transferor
Lender shall cause such Transferee, concurrently with the effectiveness of such
transfer, to comply with the provisions of Section 3.5.

                                  ARTICLE XIII

                                     NOTICES

         13.1 Notices. Except as otherwise permitted by Section 2.13 with
respect to borrowing notices, all notices, requests and other communications to
any party hereunder shall be in writing (including bank wire, facsimile
transmission or similar writing) and shall be given to such party: (x) in the
case of the Borrower or the Agent, at its address or facsimile number set forth
on the signature pages hereof, (y) in the case of any Lender, at its address or
facsimile number set forth below its signature hereto, or (z) in the case of any
party, at such other address or facsimile number as such party may hereafter
specify for the purpose by notice to the Agent and the Borrower in accordance
with the provisions of this Section 13.1. Each such notice, request or other
communication shall be effective (i) if given by facsimile transmission, when
transmitted to the facsimile number specified in this Section and confirmation
of receipt is received, (ii) if given by mail, 72 hours after such communication
is deposited in the mails with first class postage prepaid, addressed as
aforesaid, or (iii) if given by any other means, when delivered at the address
specified in this Section; provided that notices to the Agent under Article II
shall not be effective until received.

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

                                  COUNTERPARTS

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

                                   ARTICLE XV

          CHOICE OF LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL

         15.1 CHOICE OF LAW. THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING A
CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH
THE INTERNAL LAWS (AND NOT THE LAW OF CONFLICTS) OF THE STATE OF ILLINOIS, BUT
GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

         15.2 CONSENT TO JURISDICTION. THE BORROWER HEREBY IRREVOCABLY SUBMITS
TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR ILLINOIS STATE
COURT SITTING IN CHICAGO, ILLINOIS IN ANY ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO ANY TRANSACTION DOCUMENTS AND THE BORROWER HEREBY IRREVOCABLY AGREES
THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND
DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR
HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN
SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL
LIMIT THE RIGHT OF THE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE
BORROWER IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY THE
BORROWER AGAINST THE AGENT OR ANY LENDER OR ANY AFFILIATE OF THE AGENT OR ANY
LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF,
RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT
IN CHICAGO, ILLINOIS.

         15.3 WAIVER OF JURY TRIAL. THE BORROWER, THE AGENT AND EACH LENDER
HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR
INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY
WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE
RELATIONSHIP ESTABLISHED THEREUNDER.
