contrary contained in SECTION 2.8 or 2.9, no Advance may be made as, converted
into or continued as a Eurodollar Advance (except with the consent of the Agent
and the Required Lenders) when any Default or Unmatured Default has occurred and
is continuing. During the continuance of a 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 (a) each Eurodollar Advance shall bear interest for the remainder
of the applicable Interest Period at the Eurodollar Rate otherwise applicable to
such Interest Period plus 1% per annum and (b) each Alternate Base Rate Advance
shall bear interest at a rate per annum equal to the Alternate Base Rate in
effect from time to time plus 1% per annum, PROVIDED that, during the
continuance of a Default under SECTION 7.6 or 7.7, the interest rates set forth
in clauses (a) and (b) above shall be applicable to all Advances without any
election or action on the part of the Agent or any Lender.

     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

                                      -16-
<Page>

when due and shall be applied ratably by the Agent among the Lenders. 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
Bank One 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 be evidenced by a
     promissory note in substantially the form of EXHIBIT A (including any
     amendment, modification, renewal or replacement thereof, a "NOTE"). In such
     event, the Borrower shall prepare, execute and deliver to such Lender such
     Note payable to the order of such Lender. 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.
     Upon receipt of an affidavit of an officer of any Lender as to the loss,
     theft, destruction or mutilation of such Lender's Note, and, in the case of
     any such loss, theft destruction or mutilation, upon cancellation of such
     Note, the Borrower will issue, in lieu thereof, a replacement Note in the
     same principal amount thereof and otherwise of like tenor.

     2.14.   TELEPHONIC NOTICES. The Borrower hereby authorizes the Lenders and
the Agent to extend, convert or continue Advances, effect selections of Types of
Advances and to transfer funds based on telephonic notices made by any person or
persons the Agent or any Lender in good faith believes to be acting on behalf of
the Borrower, it being understood that the foregoing authorization is
specifically intended to allow Borrowing Notices and Conversion/Continuation

                                      -17-
<Page>

Notices to be given telephonically. 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.

     2.15.   INTEREST PAYMENT DATES; INTEREST AND FEE BASIS. Interest accrued on
each Alternate Base Rate Advance shall be payable on each Payment Date,
commencing with the first such date to occur after the date hereof, on any date
on which an Alternate Base Rate Advance is prepaid, whether due to acceleration
or otherwise, and at maturity. Interest accrued on that portion of the
outstanding principal amount of any Alternate Base Rate Advance converted into a
Eurodollar Advance on a day other than a Payment Date shall be payable on the
date of conversion. 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 (3) months shall also be payable on the last day of each
three-month interval during such Interest Period. Interest with respect to
Eurodollar Loans, facility fees and utilization fees shall be calculated for
actual days elapsed on the basis of a 360-day year. Interest with respect to
Alternate Base Rate Loans shall be calculated for the actual days elapsed on the
basis of a 365 or 366-day year, as applicable. 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 made in full and 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.

     2.16.   NOTIFICATION OF ADVANCES, INTEREST RATES, PREPAYMENTS AND
COMMITMENT REDUCTIONS. Promptly after receipt thereof, the Agent will notify
each Lender of the contents of each Aggregate Commitment reduction notice,
Borrowing Notice, Conversion/Continuation Notice, and repayment notice received
by it hereunder. The Agent will notify each Lender of the Eurodollar Rate
applicable to each Eurodollar Advance promptly upon determination of such
interest rate and will give each Lender prompt notice of each change in the
Alternate Base Rate.

     2.17.   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 the Loans and any Notes issued hereunder shall be
deemed held by each Lender for the benefit of any such Lending Installation.
Each Lender may, by written notice to the Agent and the Borrower in accordance
with ARTICLE XIII, designate replacement or additional Lending Installations
through which Loans will be made by it and for whose account Loan payments are
to be made.

     2.18.   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 (a) in the case of a Lender, the
proceeds of a Loan, or (b) in the case of the Borrower, a

                                      -18-
<Page>

payment of principal, interest or fees to the Agent for the account of the
Lenders, that it does not intend to make such payment, the Agent may assume that
such payment has been made. The 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 (x) in the case of payment by
a Lender, the Federal Funds Effective Rate for such day for the first three (3)
days and, thereafter, the interest rate applicable to the relevant Loan or (y)
in the case of payment by the Borrower, the interest rate applicable to the
relevant Loan.

     2.19.   EXTENSION OF REVOLVING CREDIT TERMINATION DATE AND FACILITY
TERMINATION DATE. The Borrower may request an extension of the Revolving Credit
Termination Date and Facility Termination Date by submitting a request for an
extension to the Agent (an "EXTENSION REQUEST") no more than sixty (60) days
prior to the then effective Revolving Credit Termination Date. The Extension
Request must specify the new Revolving Credit Termination Date and Facility
Termination Date requested by the Borrower and the date (which must be at least
thirty (30) days after the Extension Request is delivered to the Agent) as of
which the Lenders must respond to the Extension Request (the "RESPONSE DATE").
The new Revolving Credit Termination Date shall be no more than 364 days after
the Revolving Credit Termination Date in effect at the time the Extension
Request is received, including the current Revolving Credit Termination Date as
one of the days in the calculation of the days elapsed and the new Facility
Termination Date shall be one (1) year after the new Revolving Credit
Termination Date. Promptly upon receipt of an Extension Request, the Agent shall
notify each Lender of the contents thereof and shall request each Lender to
approve the Extension Request. Each Lender may, in its sole discretion, elect to
approve or deny such Extension Request. Failure of a Lender to respond to an
Extension Request by the Response Date shall be deemed a refusal to approve such
Extension Request. Each Lender approving the Extension Request shall deliver its
written consent no later than the Response Date. If the consent of each of the
Lenders is received by the Agent, the Revolving Credit Termination Date and
Facility Termination Date specified in the Extension Request shall become
effective on the existing Revolving Credit Termination Date and the Agent shall
promptly notify the Borrower and each Lender of the new Revolving Credit
Termination Date and Facility Termination Date. In the event that a consent is
not received from each of the Lenders, then there shall be no extension of the
existing Revolving Credit Termination Date and Facility Termination Date.

     2.20.   REPLACEMENT OF LENDER. If the Borrower is required pursuant to
SECTION 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any
Lender's obligation to make or continue, or to convert Alternate Base Rate
Advances into, Eurodollar Advances shall be suspended pursuant to SECTION 3.3
(any Lender so affected an "AFFECTED LENDER"), the Borrower may elect, if such
amounts continue to be charged or such suspension is still effective, to replace
such Affected Lender as a Lender party to this Agreement, PROVIDED that no
Default or Unmatured Default shall have occurred and be continuing at the time
of such replacement, and

                                      -19-
<Page>

PROVIDED FURTHER that, concurrently with such replacement, (i) another bank or
other entity which is reasonably satisfactory to the Borrower and the Agent
shall agree, as of such date, to purchase for cash the Advances and other
Obligations due to the Affected Lender pursuant to an assignment substantially
in the form of EXHIBIT C and to become a Lender for all purposes under this
Agreement and to assume all obligations of the Affected Lender to be terminated
as of such date and to comply with the requirements of SECTION 12.3 applicable
to assignments, and (ii) the Borrower shall pay to such Affected Lender in same
day funds on the day of such replacement (A) all interest, fees and other
amounts then accrued but unpaid to such Affected Lender by the Borrower
hereunder to and including the date of termination, including without limitation
payments due to such Affected Lender under SECTIONS 3.1, 3.2 and 3.5, and (B) an
amount, if any, equal to the payment which would have been due to such Lender on
the day of such replacement under SECTION 3.4 had the Loans of such Affected
Lender been prepaid on such date rather than sold to the replacement Lender.

                                  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
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:

               (a)  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

               (b)  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

               (c)  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 reduces any amount
     receivable by any Lender or any applicable Lending Installation in
     connection with its Eurodollar Loans, or requires any Lender or any
     applicable Lending Installation to make any payment calculated by reference
     to the amount of Eurodollar Loans held 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 or
Commitment or to reduce the

                                      -20-
<Page>

return received by such Lender or applicable Lending Installation in connection
with such Eurodollar Loans or Commitment, then, within fifteen (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 fifteen (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 or its Commitment to make Loans hereunder (after taking
into account such Lender's policies as to capital adequacy). "CHANGE" means (a)
any change after the date of this Agreement in the Risk-Based Capital Guidelines
or (b) 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 Person controlling
any Lender. "RISK-BASED CAPITAL GUIDELINES" means (a) the risk-based capital
guidelines in effect in the United States on the date of this Agreement,
including transition rules, and (b) the corresponding capital 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, interpretation or directive,
whether or not having the force of law, or if the Required Lenders determine
that (a) deposits of a type and maturity appropriate to match fund Eurodollar
Advances are not available or (b) the interest rate applicable to Eurodollar
Advances does not accurately or fairly reflect the cost of making or maintaining
Eurodollar Advances, then the Agent shall suspend the availability of Eurodollar
Advances and require any affected Eurodollar Advances to be repaid or converted
to Alternate Base 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 prior to 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. (a) 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

                                      -21-
<Page>

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, (i)
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, (ii) the Borrower shall make such deductions, (iii) the Borrower shall pay
the full amount deducted to the relevant authority in accordance with applicable
law and (iv) the Borrower shall furnish to the Agent the original copy of a
receipt evidencing payment thereof within thirty (30) days after such payment is
made.

               (b)  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").

               (c)  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. Payments due under this indemnification shall be made within
     thirty (30) days of the date the Agent or such Lender makes demand therefor
     pursuant to SECTION 3.6.

               (d)  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, not more than ten (10) Business Days after the date of
     this Agreement, (i) deliver to each of the Borrower and the Agent two duly
     completed copies of United States Internal Revenue Service Form W-8BEN or
     W-8ECI, 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, and (ii) deliver to each of the
     Borrower and the Agent a United States Internal Revenue Form W-8 or W-9, as
     the case may be, and certify that it is entitled to an exemption from
     United States backup withholding tax. Each Non-U.S. Lender further
     undertakes, to the extent lawful at such time, to deliver to each of the
     Borrower and the Agent (x) renewals or additional copies of such form (or
     any successor form) on or before the date that such form expires or becomes
     obsolete, and (y) 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

                                      -22-
<Page>

     the Borrower and the Agent that it is not capable of receiving payments
     without any deduction or withholding of United States federal income tax.

               (e)  For any period during which a Non-U.S. Lender has failed to
     provide the Borrower with an appropriate form pursuant to CLAUSE (d), 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 (d), 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.

               (f)  Any Lender that is entitled to an exemption from or
     reduction of withholding tax with respect to payments under this Agreement
     or any Note pursuant to the law of any relevant jurisdiction or any treaty
     shall deliver to the Borrower (with a copy to the Agent), at the time or
     times prescribed by applicable law, such properly completed and executed
     documentation prescribed by applicable law as will permit such payments to
     be made without withholding or at a reduced rate.

               (g)  If the U.S. Internal Revenue Service or any other
     governmental authority of the United States or any other country or any
     political subdivision thereof asserts a claim that the Agent did not
     properly withhold tax from amounts paid to or for the account of any Lender
     (because the appropriate form was not delivered or properly completed,
     because such Lender failed to notify the Agent of a change in circumstances
     which rendered its exemption from withholding ineffective, or for any other
     reason not caused by or constituting gross negligence or willful misconduct
     of the Agent), such Lender shall indemnify the Agent fully for all amounts
     paid, directly or indirectly, by the Agent as tax, withholding therefor, or
     otherwise, including penalties and interest, and including taxes imposed by
     any jurisdiction on amounts payable to the Agent under this subsection,
     together with all reasonable costs and expenses related thereto (including
     reasonable attorneys fees and reasonable time charges of attorneys for the
     Agent, which attorneys may be employees of the Agent). The obligations of
     the Lenders under this SECTION 3.5(g) shall survive the payment of the
     Obligations and termination of this Agreement.

     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 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

                                      -23-
<Page>

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. The Borrower shall have no obligation to reimburse, compensate
or indemnify any Lender with respect to a claim under this ARTICLE III if the
Lender fails to deliver such written statement within 180 days after the date on
which the Lender becomes aware of the event or occurrence giving rise to such
claim. 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 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
                              CONDITIONS PRECEDENT

     4.1.    EFFECTIVENESS. This Agreement shall not become effective unless and

               (b)  BY-LAWS AND RESOLUTIONS. Copies, certified by the Secretary

by the Secretary or Assistant Secretary of the Borrower, which shall identify by
name and title and bear the signature of the officers of the Borrower authorized
to sign the Loan Documents and to make borrowings hereunder, upon which
certificate the Agent and the Lenders shall be entitled to rely until informed
of any change in writing by the Borrower.

               (d)  OFFICER'S CERTIFICATE. A certificate, dated the date of this
Agreement, signed by an Authorized Officer of the Borrower, in form and
substance satisfactory to the Agent, to the effect that: (i) on such date (both
before and after giving effect to the making of any Loans hereunder on such
date) no Default or Unmatured Default has occurred and is continuing; (ii) each
of the representations and warranties set forth in ARTICLE V of this Agreement
is true and correct on and as of such date; and (iii) since December 31, 2000 no
event or change has occurred that has caused or evidences a Material Adverse
Effect.

                                    ARTICLE V
                         REPRESENTATIONS AND WARRANTIES

     The Borrower represents and warrants to the Lenders that:

     5.1.    CORPORATE EXISTENCE AND STANDING. Each of the Borrower and its
Subsidiaries is a corporation duly and properly incorporated, validly existing
and in good standing under the laws of its jurisdiction of incorporation and is
duly qualified and in good standing as a foreign corporation and is duly
authorized to conduct its business in each jurisdiction in which its business is
conducted or proposed to be conducted except where failure to be so qualified or
authorized could not reasonably be expected to have a Material Adverse Effect.

     5.2.    AUTHORIZATION AND VALIDITY. The Borrower has all requisite power
and authority (corporate and otherwise) and legal right to execute and deliver
each of 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.    COMPLIANCE WITH LAWS AND CONTRACTS. The Borrower and its
Subsidiaries have complied in all material respects 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
properties, except where the failure to so comply could not reasonably be
expected to have a Material Adverse Effect. Neither the execution and delivery
by the Borrower of the Loan Documents, the application of the proceeds of the
Loans, or any other transaction contemplated in the Loan Documents, nor
compliance with the provisions of the Loan Documents will, or at the relevant
time did, (a) violate any law, rule, regulation (including Regulation U), order,
writ, judgment, injunction, decree or award binding on the Borrower or any
Subsidiary or the Borrower's or any Subsidiary's charter, articles or
certificate of incorporation or by-laws, (b) violate the provisions of or
require the approval or consent of any party to any indenture, instrument or
agreement to which the Borrower or any Subsidiary is a party or is subject, or
by which it, or its property, is bound, or conflict with or constitute a default
thereunder, or result in the creation or imposition of any Lien (other than
Liens permitted by the Loan Documents) in, of or on the property of the Borrower
or any Subsidiary pursuant to the terms of any such indenture, instrument or
agreement, or (c) require any consent of the stockholders of any Person, except
for any violation of, or failure to obtain an approval or consent required
under, any such indenture, instrument or agreement that could not reasonably be
expected to have a Material Adverse Effect.

     5.4.    GOVERNMENTAL CONSENTS. No order, consent, approval, qualification,
license, authorization, or validation of, or filing, recording or registration
with, or exemption by, or other action in respect of, any court, governmental or
public body or authority, or any subdivision

                                      -26-
<Page>

thereof, any securities exchange or other Person is or at the relevant time was
required to authorize, or is or at the relevant time was required in connection
with the execution, delivery, consummation or performance of, or the legality,
validity, binding effect or enforceability of, any of the Loan Documents, the
application of the proceeds of the Loans or any other transactions contemplated
in the Loan Documents. Neither the Borrower nor any Subsidiary is in default
under or in violation of any foreign, federal, state or local law, rule,
regulation, order, writ, judgment, injunction, decree or award binding upon or
applicable to the Borrower or such Subsidiary, in each case the consequence of
which default or violation could reasonably be expected to have a Material
Adverse Effect.

     5.5.    FINANCIAL STATEMENTS. The Borrower has heretofore furnished to each
of the Lenders (a) the December 31, 2000 audited consolidated financial
statements of the Borrower and its Subsidiaries, and (b) the unaudited
consolidated financial statements of the Borrower and its Subsidiaries through
September 30, 2001 (collectively, the "FINANCIAL STATEMENTS"). Each of the
Financial Statements was prepared in accordance with Agreement Accounting
Principles and fairly presents the consolidated financial condition and
operations of the Borrower and its Subsidiaries at such dates and the
consolidated results of their operations for the respective periods then ended
(except, in the case of such unaudited statements, for normal year-end audit
adjustments).

     5.6.    MATERIAL ADVERSE CHANGE. Since December 31, 2000, there has been no
change in the business, Property, condition (financial or otherwise),
performance, prospects or results of operations of the Borrower and its
Subsidiaries taken as a whole which could reasonably be expected to have a
Material Adverse Effect.

     5.7.    TAXES. The Borrower and its Subsidiaries have filed or caused to be
filed on a timely basis and in correct form all United States federal, state and
other material tax returns which are required to be filed and have paid all
taxes due pursuant to said returns or pursuant to any assessment received by the
Borrower or any Subsidiary, 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. As of the
date hereof, the United States income tax returns of the Borrower on a
consolidated basis have been audited by the Internal Revenue Service through its
Fiscal Year ending December 31, 1989. No tax liens have been filed and no claims
are being asserted with respect to any such taxes which could reasonably be
expected to have a Material Adverse Effect. The charges, accruals and reserves
on the books of the Borrower and its Subsidiaries in respect of any taxes or
other governmental charges are in accordance with Agreement Accounting
Principles.

     5.8.    LITIGATION AND CONTINGENT OBLIGATIONS. There is no litigation,
arbitration, proceeding, inquiry or governmental investigation (including,
without limitation, by the Federal Trade Commission) pending or, to the
knowledge of any of their officers, threatened against or affecting the Borrower
or any Subsidiary or any of their respective Properties that could reasonably be
expected to have a Material Adverse Effect or to prevent, enjoin or unduly delay
the making of the Loans under this Agreement.

                                      -27-

     5.9.    ERISA. The Unfunded Liability of all Single Employer Plans does not
in the aggregate exceed twenty percent (20%) of the Total Plan Liability for all
Single Employer Plans. Neither the Borrower nor any other member of the
Controlled Group maintains, or is obligated to contribute to, any Multiemployer
Plan or has incurred, or is reasonably expected to incur, any withdrawal
liability to any Multiemployer Plan. Each Plan complies in all material respects
with all applicable requirements of law and regulations. Neither the Borrower
nor any member of the Controlled Group has, with respect to any Plan, failed to
make any contribution or pay any amount required under Section 412 of the Code
or Section 302 of ERISA or the terms of such Plan which could reasonably be
expected to have a Material Adverse Effect. There are no pending or, to the
knowledge of the Borrower, threatened claims, actions, investigations or
lawsuits against any Plan, any fiduciary thereof, or the Borrower or any member
of the Controlled Group with respect to a Plan which could reasonably be
expected to have a Material Adverse Effect. Neither the Borrower nor any member
of the Controlled Group has engaged in any prohibited transaction (as defined in
Section 4975 of the Code or Section 406 of ERISA) in connection with any Plan
which would subject such Person to any material liability. Within the last five
(5) years neither the Borrower nor any member of the Controlled Group has
engaged in a transaction which resulted in a Single Employer Plan with an
Unfunded Liability being transferred out of the Controlled Group which could
reasonably be expected to have a Material Adverse Effect. No Termination Event
has occurred or is reasonably expected to occur with respect to any Plan which
is subject to Title IV of ERISA which could reasonably be expected to have a
Material Adverse Effect.

     5.10.   DEFAULTS. No Default or Unmatured Default has occurred and is
continuing.

     5.11.   REGULATION U. Margin Stock constitutes less than 25% of those
assets of the Borrower and its Subsidiaries which are subject to any limitation
on sale, pledge or other restriction hereunder. Neither the Borrower nor any
Subsidiary is engaged, directly or indirectly, principally, or as one of its
important activities, in the business of extending, or arranging for the
extension of, credit for the purpose of purchasing or carrying Margin Stock. No
part of the proceeds of any Loan will be used in a manner which would violate,
or result in a violation of, Regulation U. Neither the making of any Advance
hereunder nor the use of the proceeds thereof will violate or be inconsistent
with the provisions of Regulation U.

     5.12.   INVESTMENT COMPANY; PUBLIC UTILITY HOLDING COMPANY. Neither the
Borrower nor any Subsidiary is, or after giving effect to any Advance will be,
an "investment company" or a company "controlled" by an "investment company"
within the meaning of the Investment Company Act of 1940, as amended. Neither
the Borrower nor any Subsidiary is 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.

     5.13.   OWNERSHIP OF PROPERTIES. As of the date of this Agreement, the
Borrower and its Subsidiaries have a subsisting leasehold interest in, or good
and marketable title, free of all Liens, other than those permitted by SECTION
6.12 or by any of the other Loan Documents, to all of the properties and assets
reflected in the Financial Statements as being owned by it, except for assets
sold, transferred or otherwise disposed of in the ordinary course of business or
as required

                                      -28-
<Page>

by or in connection with the CSC Spin-Off (provided that such sale, transfer or
other disposal in connection with the CSC Spin-Off could not reasonably be
expected to have a Material Adverse Effect) since the date thereof. The Borrower
and its Subsidiaries own or possess rights to use all licenses, patents, patent
applications, copyrights, service marks, trademarks and trade names necessary to
continue to conduct their business as heretofore conducted, and no such license,
patent or trademark has been declared invalid, been limited by order of any
court or by agreement or is the subject of any infringement, interference or
similar proceeding or challenge, except for proceedings and challenges which
could not reasonably be expected to have a Material Adverse Effect.

     5.14.   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 or which restricts or imposes conditions upon the ability of any
Subsidiary to (a) pay dividends or make other distributions on its capital
stock, (b) make loans or advances to the Borrower or (c) repay loans or advances
from the Borrower. 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 any agreement to which it is a party, which default
could reasonably be expected to have a Material Adverse Effect.

     5.15.   ENVIRONMENTAL LAWS. There are no claims, investigations,
litigation, administrative proceedings, notices, requests for information (each
a "PROCEEDING"), whether pending or threatened, or judgments or orders asserting
violations of applicable federal, state and local environmental, health and
safety statutes, regulations, ordinances, codes, rules, orders, decrees,
directives and standards ("ENVIRONMENTAL LAWS") or relating to any toxic or
hazardous waste, substance or chemical or any pollutant, contaminant, chemical
or other substance defined or regulated pursuant to any Environmental Law,
including, without limitation, asbestos, petroleum, crude oil or any fraction
thereof ("HAZARDOUS MATERIALS") asserted against the Borrower or any of its
Subsidiaries which, in any case, could reasonably be expected to have a Material
Adverse Effect. Neither the Borrower nor any Subsidiary has caused or permitted
any Hazardous Materials to be released, either on or under real property,
currently or formerly, legally or beneficially owned or operated by the Borrower
or any Subsidiary or on or under real property to which the Borrower or any of
its Subsidiaries transported, arranged for the transport or disposal of, or
disposed of Hazardous Materials, which release could reasonably be expected to
have a Material Adverse Effect.

     5.16.   INSURANCE. The Borrower and its Subsidiaries maintain, with
financially sound and reputable insurance companies, insurance on their Property
in such amounts and covering such risks as is consistent with sound business
practice.

     5.17.   INSURANCE LICENSES. No material license, permit or authorization of
the Borrower or any Subsidiary to engage in the business of insurance or
insurance-related activities is the subject of a proceeding for suspension or
revocation, except where such suspension or revocation would not individually or
in the aggregate have a Material Adverse Effect.

                                      -29-
<Page>

     5.18.   SOLVENCY. Immediately after the consummation of the CSC Spin-Off
and the making of any Loans related thereto, (a) the fair value of the assets of
the Post-Spin-Off Group on a consolidated basis, at a fair valuation, will
exceed the debts and liabilities, subordinated, contingent or otherwise, of the
Post-Spin-Off Group on a consolidated basis; (b) the present fair saleable value
of the Property of the Post-Spin-Off Group on a consolidated basis will be
greater than the amount that will be required to pay the probable liability of
the Post-Spin-Off Group 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 Post-Spin-Off Group 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 Post-Spin-Off Group 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 as proposed to
be conducted taking into account the CSC Spin-Off.

     5.19.   DISCLOSURE. None of the (a) information, exhibits or reports
furnished or to be furnished by the Borrower or any Subsidiary to the Agent or
to any Lender in connection with the negotiation of the Loan Documents, or (b)
representations or warranties of the Borrower or any Subsidiary contained in
this Agreement, the other Loan Documents, or any other document, certificate or
written statement furnished to the Agent or the Lenders by or on behalf of the
Borrower or any Subsidiary for use in connection with the transactions
contemplated by this Agreement, as the case may be, contained, contains or will
contain any untrue statement of a material fact or omitted, omits or will omit
to state a material fact necessary in order to make the statements contained
herein or therein not misleading in light of the circumstances in which the same
were made. As of the date hereof, there is no fact known to the Borrower (other
than matters of a general economic nature) that has had or could reasonably be
expected to have a Material Adverse Effect and that has not been disclosed
herein or in such other documents, certificates and statements furnished to the
Lenders for use in connection with the transactions contemplated by this
Agreement.

                                   ARTICLE VI

to finance the acquisition of any Person which has not been approved and
recommended by the board of directors (or functional equivalent thereof) of such
Person.

     6.3.    NOTICE OF DEFAULT. The Borrower will give prompt notice in writing
to the Lenders of the occurrence of (a) any Default or Unmatured Default and (b)
of any other event or development, financial or other, relating specifically to
the Borrower or any of its Subsidiaries (and not of a general economic or
political nature) which could reasonably be expected to have a Material Adverse
Effect.

Transitional Services.

Adverse Effect.

                                      -32-
<Page>

     6.8.    MAINTENANCE OF PROPERTIES. The Borrower will, and will cause each

its Property in good repair, working order and condition, and make all necessary
and proper repairs, renewals and replacements so that its business carried on in
connection therewith may be properly conducted at all times.

     6.9.    INSPECTION. The Borrower will, and will cause each Subsidiary to,
permit the Agent and the Lenders, by their respective representatives and
agents, to inspect any of the Property, corporate books and financial records of
the Borrower and each Subsidiary, to examine and make copies of the books of
accounts and other financial records of the Borrower and each Subsidiary, and to
discuss the affairs, finances and accounts of the Borrower and each Subsidiary
with, and to be advised as to the same by, their respective officers at such
reasonable times and intervals as the Lenders may designate. The Borrower will
keep or cause to be kept, and cause each Subsidiary to keep or cause to be kept,
appropriate records and books of account in which complete entries are to be
made reflecting its and their business and financial transactions, such entries
to be made in accordance with Agreement Accounting Principles consistently
applied.

     6.10.   CAPITAL STOCK AND DIVIDENDS. So long as any Default or Unmatured
Default has occurred and is continuing, the Borrower will not declare or pay any
dividends or make any distributions on its capital stock (other than dividends
payable in its own capital stock) or redeem, repurchase or otherwise acquire or
retire any of its capital stock or any options or other rights in respect
thereof at any time outstanding, other than any such dividend or distribution
required in connection with the CSC Spin-Off; PROVIDED that no such dividend or
distribution could reasonably be expected to have a Material Adverse Effect.

     6.11.   MERGER. Except with respect to any transaction or step required in
connection with the CSC Spin-Off (provided that no such transaction or step
could reasonably be expected to have a Material Adverse Effect), the Borrower
will not, nor will it permit any Subsidiary to, merge or consolidate with or
into any other Person, except that (a) a Wholly-Owned Subsidiary may merge into
the Borrower or any Wholly-Owned Subsidiary of the Borrower, (b) the Borrower or
any Subsidiary may merge or consolidate with any other Person so long as the
Borrower or such Subsidiary is the continuing or surviving corporation and,
prior to and after giving effect to such merger or consolidation, no Default or
Unmatured Default shall exist, and (c) any Subsidiary may enter into a merger or
consolidation as a means of effecting a disposition or acquisition which would
not result in a Default or Unmatured Default.

Borrower or any of its Subsidiaries, except:

               (a)  Liens for taxes, assessments or governmental charges or
levies on its Property if the same shall not at the time be delinquent or
thereafter can be paid without penalty, or are being contested in good faith and
by appropriate proceedings and for which adequate reserves in accordance with
generally accepted principles of accounting shall have been set aside on its
books;

               (f)  Any Lien arising by operation of law in the ordinary course
of trading in respect of any obligation which is less than sixty (60) days
overdue or which is being contested in good faith and by appropriate means and
for which adequate reserves have been made;

               (g)  Encumbrances created by any of the Borrower or its
Subsidiaries over deposits and investments in the ordinary course of such
Person's insurance and reinsurance trade to comply with the requirements of any

when the sum of (i) the aggregate principal amount of all obligations secured
pursuant to this SECTION 6.12(h) plus (ii) the aggregate Unfunded Liability of
all Single Employer Plans exceeds ten percent (10%) of Consolidated Net Worth,
the creation of additional Liens otherwise allowed hereunder shall be permitted
by this SECTION 6.12(h) only to the extent they secure an aggregate principal
amount of obligations not in excess of one percent (1%) of Consolidated Net
Worth.

     6.13.   AFFILIATES. The Borrower will not, and will not permit any
Subsidiary to, enter into any transaction (including, without limitation, the

any Wholly-Owned Subsidiary of the Borrower or between Wholly-Owned Subsidiaries
of the Borrower, (b) in the ordinary course of business and pursuant to the
reasonable requirements of the Borrower's or such Subsidiary's business and upon
fair and

                                      -34-
<Page>

reasonable terms no less favorable to the Borrower or such Subsidiary than the
Borrower or such Subsidiary would obtain in a comparable arms-length transaction
and (c) as required in connection with the CSC Spin-Off; PROVIDED that no such
transaction, payment or transfer could reasonably be expected to have a Material
Adverse Effect.

     6.14.   CHANGE IN FISCAL YEAR. The Borrower shall not change its Fiscal
Year to end on any date other than December 31 of each year.

     6.15.   INCONSISTENT AGREEMENTS. The Borrower shall not, nor shall it
permit any Subsidiary to, enter into any indenture, agreement, instrument or
other arrangement which, (a) directly or indirectly prohibits or restrains, or
has the effect of prohibiting or restraining, or imposes materially adverse
conditions upon, the incurrence of the Obligations, the amending of the Loan
Documents or the ability of any Subsidiary to (i) pay dividends or make other
distributions on its capital stock, (ii) make loans or advances to the Borrower
or (iii) repay loans or advances from the Borrower or (b) contains any provision
which would be violated or breached by the making of Advances or by the
performance by the Borrower of any of its obligations under any Loan Document.

     6.16.   SALE OF ASSETS. Except with respect to any transaction or step
required in connection with the CSC Spin-Off (provided that no such transaction
or step could reasonably be expected to have a Material Adverse Effect), the
Borrower will not, nor will it permit any Subsidiary to, lease, sell or
otherwise dispose of Property which represents more than 25% of the consolidated
assets of the Borrower and its Subsidiaries, as would be shown in the
consolidated financial statements of the Borrower and its Subsidiaries as at the
end of the quarter immediately preceding the date on which such determination is
made, to any other Person(s) in any Fiscal Year.

     6.17.   Financial Covenants.

             6.17.1.   MINIMUM CONSOLIDATED NET WORTH. The Borrower shall at all
     times prior to the CSC Spin-Off maintain a minimum Consolidated Net Worth
     of at least $2,500,000,000 and shall at all times from and after the CSC
     Spin-Off maintain a minimum Consolidated Net Worth of at least
     $2,000,000,000.

             6.17.2.   CONSOLIDATED EBITDA TO CONSOLIDATED INTEREST EXPENSE. The
     Borrower will maintain, as at the last day of each of its fiscal quarters,
     a ratio of (a) Consolidated EBITDA to (b) Consolidated Interest Expense, in
     each case calculated for the four fiscal quarters then ending, of not less
     than 4.0 to 1.0.

     6.18.   ERISA. The Borrower will (a) fulfill, and cause each member of the
Controlled Group to fulfill, its obligations under the minimum funding standards
of ERISA and the Code with respect to each Plan, except where a failure to
fulfill such obligations individually or in the aggregate could not reasonably
be expected to have a Material Adverse Effect, (b) comply, and cause each member
of the Controlled Group to comply, with all applicable provisions of ERISA and
the Code with respect to each Plan, except where such failure or noncompliance
individually

                                      -35-
<Page>

or in the aggregate would not have a Material Adverse Effect and (c) not, and
not permit any member of the Controlled Group to, (i) seek a waiver of the
minimum funding standards under ERISA, (ii) terminate or withdraw from any Plan
or (iii) take any other action with respect to any Plan which would reasonably
be expected to entitle the PBGC to terminate, impose liability in respect of, or
cause a trustee to be appointed to administer, any Plan, unless the actions or
events described in the foregoing clauses (i), (ii) or (iii) individually or in
the aggregate would not have a Material Adverse Effect.

Indebtedness to become due prior to its stated maturity; or any such
Indebtedness of the Borrower or any of its Subsidiaries shall be declared to be
due and payable or required to be prepaid (other than by a regularly scheduled

                                  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
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
with the consent or upon the instruction of the Required Lenders) may terminate
or

                                      -37-
<Page>

suspend the obligations of the Lenders to make Loans 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, within ten (10) Business Days after acceleration of the maturity of the
Obligations or termination of the obligations of the Lenders to make Loans
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 (or, in the case of an acceleration and/or
termination upon the occurrence of a Default under SECTION 7.10, the Modified
Required Lenders), in their sole 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 Loan Documents or changing
in any manner the rights of the Lenders or the Borrower hereunder or thereunder
or waiving any Default hereunder or thereunder; PROVIDED, HOWEVER, that no such
supplemental agreement shall, without the consent of each Lender:

               (a)  Extend the Facility Termination Date or the Revolving Credit
Termination Date, compromise or forgive the principal amount of any Loan, or
reduce the rate of interest or compromise or forgive payment of interest on any
Loan, or reduce the amount of any fee payable hereunder;

               (b)  Reduce the percentage specified in the definition of
Required Lenders or Modified Required Lenders;

               (c)  Increase the amount of the Commitment of any Lender
hereunder (except pursuant to SECTION 2.5(b));

               (d)  Amend this SECTION 8.2; or

               (e)  Permit any assignment by the Borrower of its Obligations or
its rights hereunder.

PROVIDED, FURTHER, that no such supplemental agreement shall, without the
consent of the Modified Required Lenders amend the definition of "Change of
Control" or amend or waive SECTION 7.10.

     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.

                                      -38-
<Page>

     Notwithstanding the foregoing, upon the execution and delivery of all
documentation required by SECTION 2.5(b) to be delivered in connection with an
increase to the Aggregate Commitment, the Agent, the Borrower and the new or
existing Lenders whose Commitments have been affected may and shall enter into
an amendment hereof (which shall be binding on all parties hereto) solely for
the purpose of reflecting any new Lenders and their new Commitments and any
increase in the Commitment of any existing Lender.

     8.3.    PRESERVATION OF RIGHTS. No delay or omission of the Lenders or the
Agent to exercise any right under the Loan 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 Loan 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 Loan 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 or of the Borrower or any Subsidiary
contained in any Loan Document shall survive the making of the Loans herein
contemplated.

     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 Loan Documents are for
convenience of reference only, and shall not govern the interpretation of any of
the provisions of the Loan Documents.

     9.4.    ENTIRE AGREEMENT. The Loan Documents embody the entire agreement
and understanding among the Borrower, the Agent and the Lenders and supersede
all prior agreements and understandings among the Borrower, the Agent and the
Lenders relating to the subject matter thereof other than the fee letter
described in SECTION 10.13.

     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

                                      -39-
<Page>

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 or the
Arranger, which attorneys may be employees of the Agent or the Arranger) paid or
incurred by the Agent or the Arranger in connection with the preparation,
negotiation, execution, delivery, syndication, distribution (including, without
limitation, via the internet), review, amendment, modification, and
administration of the Loan 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, the Arranger or the Lenders) paid or incurred by the Agent, the
Arranger or any Lender in connection with the collection of the Obligations or
the enforcement of the Loan Documents. The Borrower further agrees to indemnify
the Agent, the Arranger, each Lender, their respective affiliates, and each of
their directors, officers and employees against all losses, claims, damages,
penalties, judgments, liabilities and expenses (including, without limitation,
all expenses of litigation or preparation therefor whether or not the Agent, the
Arranger, any Lender or any affiliate is a party thereto) which any of them may
pay or incur arising out of or relating to this Agreement, the other Loan
Documents, the transactions contemplated hereby, or the direct or indirect
application or proposed application of the proceeds of any Loan hereunder except
to the extent that they are determined in a final non-appealable judgment by a
court of competent jurisdiction 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 Loan 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 Loan Documents are declared to be severable.

     9.10.   NONLIABILITY OF LENDERS. The relationship between the Borrower on
the one hand and the Lenders and the Agent on the other hand shall be solely
that of borrower and lender. Neither the Agent, the Arranger nor any Lender
shall have any fiduciary responsibilities to the

                                      -40-
<Page>

Borrower. Neither the Agent, the Arranger 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. 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, consequential or punitive damages suffered by the Borrower in
connection with, arising out of, or in any way related to the Loan 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 its Affiliates and to other Lenders and
their respective Affiliates, (ii) to legal counsel, accountants, and other
professional advisors to such 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 Person in connection with any legal
proceeding to which such Lender is a party, (vi) to such Lender's direct or
indirect contractual counterparties in swap agreements or to legal counsel,
accountants and other professional advisors to such counterparties, and (vii)
permitted by Section 12.4.

     9.12.   DISCLOSURE. The Borrower and each Lender hereby acknowledge and
agree that Bank One and/or its Affiliates from time to time may hold investments
in, make other loans to or have other relationships with the Borrower and its
Affiliates.

                                    ARTICLE X
                                    THE AGENT

     10.1.   APPOINTMENT. Bank One, NA is hereby appointed by each of the
Lenders as its contractual representative (herein referred to as the "Agent")
hereunder and under each other Loan Document, and each of the Lenders
irrevocably (subject to Section 10.12) 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 Loan 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 Loan
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 Loan 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 1-201 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 Loan 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.

     10.2.   POWERS. The Agent shall have and may exercise such powers under the
Loan Documents as are specifically delegated to the Agent by the terms of each
thereof, together with

                                      -41-
<Page>

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 Loan 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 or any Lender for
any action taken or omitted to be taken by it or them hereunder or under any
other Loan Document or in connection herewith or therewith except to the extent
such action or inaction is determined in a final non-appealable judgment by a
court of competent jurisdiction to have arisen from the gross negligence or
willful misconduct of such Person.

     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 (a) any statement, warranty
or representation made in connection with any Loan Document or any borrowing
hereunder; (b) the performance or observance of any of the covenants or
agreements of any obligor under any Loan Document, including, without
limitation, any agreement by an obligor to furnish information directly to each
Lender; (c) the satisfaction of any condition specified in ARTICLE IV, except
receipt of items required to be delivered solely to the Agent; (d) the existence
or possible existence of any Default or Unmatured Default; (e) the validity,
enforceability, effectiveness, sufficiency or genuineness of any Loan Document
or any other instrument or writing furnished in connection therewith; (f) the
value, sufficiency, creation, perfection or priority of any Lien in any
collateral security; or (g) 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 Loan Document in accordance with written instructions signed by the
Required Lenders or, if expressly required hereunder, the Modified Required
Lenders or all the Lenders, and such instructions and any action taken or
failure to act pursuant thereto shall be binding on all of the Lenders. 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 or any other Loan Document unless it shall be requested in
writing to do so by the Required Lenders or, if expressly required hereunder,
the Modified Required Lenders or all the Lenders. The Agent shall be fully
justified in failing or refusing to take any action hereunder and under any
other Loan 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.

     10.6.   EMPLOYMENT OF AGENTS AND COUNSEL. The Agent may execute any of its
duties as Agent hereunder and under any other Loan Document by or through
employees, agents and attorneys-in-fact and shall not be answerable to the
Lenders, except as to money or securities

                                      -42-
<Page>

received by it or its authorized agents, for the default or misconduct of any
such agents or 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 Loan 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 (or, if the Commitments have been terminated, in proportion to their
Commitments immediately prior to such termination) (i) for any amounts not
reimbursed by the Borrower for which the Agent is entitled to reimbursement by
the Borrower under the Loan 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 Loan 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 Loan
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 of the Loan Documents or of any such other
documents, PROVIDED that (i) 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 and (ii) any indemnification required
pursuant to SECTION 3.5(g) shall, notwithstanding the provisions of this SECTION
10.8, be paid by the relevant Lender in accordance with the provisions thereof.
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 Loan
Document with respect to its Commitment and its Loans 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

                                      -43-
<Page>

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 Loan Document,
with the Borrower or any of its Subsidiaries in which the Borrower or such
Subsidiary is not restricted 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 Loan
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 Loan 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, 45 days after the retiring Agent gives notice of its intention to
resign. The Agent may be removed at any time with or without cause by written
notice received by the Agent from the Required Lenders, such removal to be
effective on the date specified by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint, on
behalf of the Borrower and the Lenders, a successor Agent. If no successor Agent
shall have been so appointed by the Required Lenders within thirty (30) 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. 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 the
Agent has resigned or been removed 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; PROVIDED, such
Lenders so performing such duties shall be deemed to be an Agent hereunder with
full benefit of all provisions indemnifying the Agent hereunder. 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 or removed Agent. Upon
the effectiveness of the resignation or removal of the Agent, the resigning or
removed Agent shall be discharged from its duties and obligations hereunder and
under the Loan Documents. After the effectiveness of the resignation or removal
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 Loan
Documents. In the event that there is a successor to the

                                      -44-
<Page>

Agent by merger, or the Agent assigns its duties and obligations to an Affiliate
pursuant to this SECTION 10.12, then the term "Prime Rate" as used in this
Agreement shall mean the prime rate, base rate or other analogous rate of the
new Agent.

     10.13.  AGENT AND ARRANGER FEES. The Borrower agrees to pay to the Agent
and the Arranger, for their respective accounts, the fees agreed to by the
Borrower, the Agent and the Arranger pursuant to that certain letter agreement
dated November 28, 2001, or as otherwise agreed from time to time.

     10.14.  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 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.

     10.15.  SYNDICATION AGENTS; SENIOR MANAGING AGENTS; MANAGING AGENTS. None
of the Lenders identified in this Agreement as the "Syndication Agents", "Senior
Managing Agents" or "Managing Agents" shall have any right, power, obligation,
liability, responsibility or duty under this Agreement in such identified
capacity other than those applicable to all Lenders as such. Without limiting
the foregoing, none of such Lenders shall have or be deemed to have a fiduciary
relationship with any Lender. Each Lender hereby makes the same acknowledgments
with respect to such Lenders as it makes with respect to the Agent in SECTION
10.11.

                                   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 thereof, shall then be due.

     11.2.   RATABLE PAYMENTS. If any Lender, whether by setoff or otherwise,
has payment made to it upon its Loans (other than payments received pursuant to
SECTION 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any
other Lender, such Lender agrees, promptly upon demand, to purchase a portion of
the Loans held by the other Lenders so that after such purchase each Lender will
hold its ratable proportion of Loans. 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. If an
amount to be setoff is to be applied to Indebtedness of the Borrower to a
Lender,

                                      -45-
<Page>

other than Indebtedness comprised of Loans made by such Lender, such amount
shall be applied ratably to such other Indebtedness and to the Indebtedness
comprised of such Loans.

                                  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. The parties to this Agreement acknowledge that clause (ii) of
this SECTION 12.1 relates only to absolute assignments and does not prohibit
assignments creating security interests, including, without limitation, (x) any
pledge or assignment by any Lender of all or any portion of its rights under
this Agreement and any Note to a Federal Reserve Bank or (y) in the case of a
Lender which is a Fund, any pledge or assignment of all or any portion of its
rights under this Agreement and any Note to its trustee in support of its
obligations to its trustee; PROVIDED, HOWEVER, that no such pledge or assignment
creating a security interest shall release the transferor Lender from its
obligations hereunder unless and until the parties thereto have complied with
the provisions of SECTION 12.3. The Agent may treat the Person which made any
Loan or which holds any Note as the owner thereof for all purposes hereof unless
and until such Person complies with SECTION 12.3; PROVIDED, HOWEVER, that the
Agent may in its discretion (but shall not be required to) follow instructions
from the Person which made any Loan or which holds any Note to direct payments
relating to such Loan or Note to another Person. Any assignee of the rights to
any Loan or any Note agrees by acceptance of such assignment to be bound by all
the terms and provisions of the Loan 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 owner of the rights to any Loan (whether or not a
Note has been issued in evidence thereof), shall be conclusive and binding on
any subsequent holder or assignee of the rights to such Loan.

     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 of such Lender or any other interest of such
     Lender under the Loan Documents. In the event of any such sale by a Lender
     of participating interests to a Participant, such Lender's obligations
     under the Loan 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 owner of its Loans and the holder
     of any Note issued to it in evidence thereof for all purposes under the
     Loan 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 Loan Documents.

                                      -46-
<Page>

             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 Loan Documents other than
     any amendment, modification or waiver with respect to any Loan or
     Commitment in which such Participant has an interest which would require
     consent of all of the Lenders pursuant to the terms of SECTION 8.2 or of
     any other Loan Document.

             12.2.3.   BENEFIT OF SETOFF. The Borrower agrees that each
     Participant which has been identified as such to the Borrower in writing
     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 Loan
     Documents to the same extent as if the amount of its participating interest
     were owing directly to it as a Lender under the Loan 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 Loan Documents. Such
     assignment shall be substantially in the form of EXHIBIT C or in such other
     form as may be agreed to by the parties thereto. The consent 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, an Affiliate
     thereof or an Approved Fund; 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 or delayed. Each
     such assignment with respect to a Purchaser which is not a Lender or an
     Affiliate thereof shall (unless each of the Borrower and the Agent
     otherwise consents) be in an amount not less than the lesser of (i)
     $5,000,000 or (ii) the remaining amount of the assigning Lender's
     Commitment (calculated as at the date of such assignment) or outstanding
     Loans (if the applicable Commitment has been terminated).

             12.3.2.   EFFECT; EFFECTIVE DATE. Upon (i) delivery to the Agent of
     an assignment, together with any consents required by SECTION 12.3.1, and
     (ii) payment of a $4,000 fee to the Agent for processing such assignment,
     such assignment shall become effective on the effective date specified in
     such assignment. The assignment shall contain a representation by the
     Purchaser to the effect that none of the consideration used to make the
     purchase of the Commitment and Loans under the applicable assignment
     agreement constitutes "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

                                      -47-
<Page>

     Lender party to this Agreement and any other Loan Document executed by or
     on behalf of the Lenders and shall have all the rights and obligations of a
     Lender under the Loan 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 Aggregate Commitment and Loans
     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 respective Commitments, as adjusted pursuant to such assignment.

     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 Loan 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 Loan 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(d).

                                      -48-

                                  ARTICLE XIII
                                     NOTICES

     13.1.   GIVING NOTICE. Except as otherwise permitted by SECTION 2.14 with
respect to borrowing notices, all notices, requests and other communications to
any party hereunder shall be in writing (including electronic transmission,
facsimile transmission or similar writing) and shall be given to such party: (x)

forth on the signature pages hereof, (y) in the case of any Lender, at its

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
(or, in the case of electronic transmission, received) 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.

                                   ARTICLE XIV
                                  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 (INCLUDING, WITHOUT LIMITATION, 735 ILCS SECTION 105/5-1 ET
SEQ, BUT OTHERWISE WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS) OF THE
STATE OF ILLINOIS, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL

ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN 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.

RELATIONSHIP ESTABLISHED THEREUNDER.

</Table>

          Subject to the following two sentences, a particular Level Status
     shall exist on a particular day if on such day the Borrower does not
     qualify for a Level Status with more advantageous pricing and either the
     Moody's Rating or the S&P Rating is at least equal to the corresponding
     rating specified for such Level Status in the table above. In the event of
     a difference in the equivalent "rating level" from S&P and Moody's
     resulting in a split of only one level, then the Level Status shall be
     determined by reference to the higher of the two Ratings. In

     ----------
     *    The Applicable Utilization Fee Rate shall be payable (i) on and after
          the Revolving Credit Termination Date, at all times and (ii) prior to
          the Revolving Credit Termination Date, only with respect to
          outstanding Advances on days when Utilization is greater than 33%.
          "Utilization" means, for any day, a percentage equal to the aggregate
          principal amount of Loans hereunder and "Loans" (as defined in the
          Three Year Agreement) outstanding on such day (and at the close of
          business on such day if a Business Day) divided by the sum on such day
          of the Aggregate Commitment and the "Aggregate Commitment" under the
          Three Year Agreement; PROVIDED that for purposes of computing the
          Utilization Fee (a) the Aggregate Commitment shall be deemed to in no
          event be less than the aggregate outstanding principal amount of the
          Loans and (b) the "Aggregate Commitment" (as defined in the Three Year
          Agreement) shall be deemed to in no event be less than the aggregate
          outstanding principal amount of the "Loans" (as defined in the Three
          Year Agreement). At all times on and after the Revolving Credit
          Termination Date the Applicable Utilization Fee Rate for each Level
          Status shall be in an amount .125% greater than the amount set forth
          for such Level Status in the above table.

<Page>

the event of a difference in the equivalent "rating level" from S&P and Moody's
resulting in a split of greater than one level, then the Level Status shall be
that Level Status one below the Level Status determined by reference to the
higher of the two Ratings. The above ratings are in the format of S&P
Rating/Moody's Rating.

     For the purposes of this Schedule, the following terms have the following
meanings, subject to the final paragraph of this Schedule:

     "Level Status" means either Level I Status, Level II Status, Level III
Status, Level IV Status, Level V Status or Level VI Status.

     "Moody's Rating" means, at any time, the Borrower Debt Rating issued by
Moody's and then in effect.

     "Rating" means Moody's Rating or S&P Rating.

     "S&P Rating" means, at any time, the Borrower Debt Rating issued by S&P and
then in effect.

     The Applicable Margin and Applicable Facility Fee Rate shall be determined
in accordance with the foregoing table based on the Borrower's Level Status as
determined from its then-current Moody's and S&P Ratings. The Rating in effect
on any date for the purposes of this Schedule is that in effect at the close of
business on such date. If at any time the Borrower has no Moody's Rating or no
S&P Rating or the Borrower does not qualify for a Level Status with more
advantageous pricing, Level VI Status shall exist.
