   written notice to the Agent, which notice shall specify the amount of any
   such reduction, provided, however, that the amount of the Aggregate
   Commitment may not be reduced below the aggregate principal Dollar Amount of
   the outstanding Advances. All accrued interest and fees shall be payable on
   the effective date of any termination of the obligations of the Lenders to
   make Loans hereunder.......................................................21

   minimum aggregate amount of $1,000,000 or any integral multiple of $100,000
   in excess thereof, any portion of the outstanding Floating Rate Advances upon
   5 days' prior notice to the Agent. Fixed Rate Advances may be paid prior to
   the last day of the applicable Interest Period, subject to compliance with
   SECTION 3.4; PROVIDED, however, that Quoted Rate Advances may not be repaid
   prior to the last day of their respective Interest Periods. Principal
   payments made after the Revolving Credit Termination Date shall be applied to
   the principal installments payable under SECTION 2.3(d) in the inverse order
   of maturity................................................................22
   2.10.   METHOD OF SELECTING TYPES AND INTEREST PERIODS FOR NEW U.S. DOLLAR

   time to time in accordance with this Section 2.11 request the Lenders to make
   one or more Alternate Currency Advances. The Lenders shall have no obligation
   to make any such Alternate Currency Advance so requested by the Borrower. If,
   and only if, each of the Lenders in its sole and absolute discretion agrees,
   in the manner provided for in this Section 2.11, to make its respective Loan
   comprising any such Alternate Currency Advance, will such Alternate Currency
   Advance be made............................................................23
   2.12.   MAKING THE LOANS. Subject to SECTION 2.10, on each Borrowing Date,
   each Lender shall make available its Loan or Loans comprising the Advance or

   currency in the city of and at the address of the Agent's Lending
   Installation for such currency. The Agent will make the funds so received
   from the Lenders available to the Borrower at the Agent's aforesaid
   address....................................................................24

   Outstanding U.S. Dollar Advances may be continued as or converted into U.S.
   Dollar Advances of the same or

                                      - 3 -
<Page>

   another Type as provided below in this Section 2.13; PROVIDED, that
   notwithstanding anything else in this Section 2.13 to the contrary, (a)
   outstanding U.S. Dollar Advances may not be converted into Alternate Currency
   Advances pursuant to this Section 2.13 and (b) outstanding Alternate Currency
   Advances may not be continued or converted pursuant to this Section 2.13, but
   must be repaid on or prior to the last day of their respective Interest
   Periods pursuant to SECTION 2.3(a) and may only be reborrowed pursuant to
   SECTIONS 2.1(b) and 2.11...................................................24
   2.14.   RESTRICTIONS ON INTEREST PERIODS. No Interest Period may extend
   beyond a Payment Date on which principal of the Advances shall be payable
   unless outstanding principal of Floating Rate Advances and Fixed Rate
   Advances with Interest Periods ending prior to said Payment Date shall be at
   least equal to the amount so payable. No Interest Period shall extend beyond
   the Facility Termination Date. No more than 10 Interest Periods may be in
   effect at any one time. No more than three Quoted Rate Interest Periods may
   be in effect at any one time...............................................26
   2.15.   CHANGES IN INTEREST RATE, ETC. Changes in the rate of interest on
   that portion of any Advance maintained as a Floating Rate Advance will take
   effect simultaneously with each change in the Alternate Base Rate and each
   change in the Applicable Margin applicable thereto. Each Fixed Rate Advance
   shall bear interest from and including the first day of the Interest 26
   Period applicable thereto to but excluding the last day of such Interest
   Period at the interest rate determined as applicable to such Fixed Rate
   Advance, provided that the rate of interest on each Eurodollar Advance will
   change simultaneously with each change, during the applicable Eurodollar
   Interest Period, of the Applicable Margin..................................26
   2.16.   RATES APPLICABLE AFTER DEFAULT. 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 (i) each Fixed Rate Advance shall
   bear interest for the remainder of the applicable Interest Period at the rate
   otherwise applicable to such Interest Period plus 2% per annum and (ii) each
   Floating Rate Advance shall bear interest at a rate per annum equal to the
   Floating Rate otherwise applicable to the Floating Rate Advance plus 2% per
   annum......................................................................26
   2.17.   METHOD OF PAYMENT. (a) All payments of principal, interest and fees
   to be made by the Borrower hereunder or under the Notes in U.S. Dollars 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 (local time) on the date 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 which the Agent received at such
   Lender's address specified pursuant to ARTICLE XIII or at any Lending
   Installation specified in a notice received by the Agent from such Lender..26
   2.18.   FOREIGN TAXES. (a) All payments made by the Borrower in respect of
   principal of and interest on the Advances and of all other amounts payable by
   it under this Agreement are payable without deduction for or on account of
   any present or future taxes, duties, withholdings or other charges levied or
   imposed by the government of any jurisdiction outside

                                      - 4 -
<Page>

   the United States of America or by any political subdivision or taxing
   authority thereof or therein (herein called "FOREIGN TAXES"). If the Borrower
   shall be required by law to deduct or withhold any Foreign Taxes from any
   such amount payable by it hereunder or under any of the Notes to or for the
   account of any Lender, (i) such amount shall be increased as may be necessary
   so that, after making such deductions or withholdings (including any
   deductions or withholdings applicable to additional amounts payable pursuant
   to this Section), such Lender receives an amount equal to the amount it would
   have received had no such deductions or withholdings been made and (ii) the
   Borrower shall make such deductions and withholdings and pay the amount
   thereof to the relevant government, political subdivision or taxing authority
   at or prior to the time required to be paid under applicable law (and shall
   promptly furnish to the Agent, for the benefit of the Lenders, official
   receipts evidencing such payment). In addition, the Borrower will pay any
   present or future stamp or documentary taxes or similar taxes or levies
   imposed by any government, political subdivision or taxing authority referred
   to in the first sentence of this subsection arising from any payment by it
   hereunder or under any of the Notes or from the execution, delivery or
   registration of, or otherwise with respect to, this Agreement or any of the
   Notes (herein called "OTHER TAXES"). The Borrower will indemnify each Lender
   and the Agent for, and hold each Lender and the Agent harmless against, the
   full amount of Foreign Taxes or Other Taxes (including, without limitation,
   any Foreign Taxes or Other Taxes imposed by any jurisdiction on amounts
   payable under this Section) paid or payable by such Lender or the Agent and
   any liability of such Lender or the Agent relating thereto (including,
   without limitation, penalties, interest and expenses)......................27
   2.19.   JUDGMENT CURRENCY. If for the purposes of obtaining judgment in any
   court it is necessary to convert a sum due from the Borrower hereunder or
   under any of the Notes in the currency expressed to be payable herein or
   under the Notes (the "SPECIFIED CURRENCY") into another currency, the parties
   hereto agree, to the fullest extent that they may effectively do so, that the
   rate of exchange used shall be that at which in accordance with normal
   banking procedures the Agent could purchase the specified currency with such
   other currency at the Agent's main Chicago office on the Business Day
   preceding that on which final, nonappealable judgment is given. The
   obligations of the Borrower in respect of any sum due to any Lender or the
   Agent hereunder or under any Note shall, notwithstanding any judgment in a
   currency other than the specified currency, be discharged only to the extent
   that on the Business Day following receipt by such Lender or the Agent (as
   the case may be) of any sum adjudged to be so due in such other currency such
   Lender or the Agent (as the case may be) may in accordance with normal,
   reasonable banking procedures purchase the specified currency with such other
   currency. If the amount of the specified currency so purchased is less than
   the sum originally due to such Lender or the Agent (as the case may be), in
   the specified currency, the Borrower agrees, to the fullest extent that it
   may effectively do so, as a separate obligation and notwithstanding any such
   judgment, to indemnify such Lender or the Agent (as the case may be) against
   such loss, and if the amount of the specified currency so purchased exceeds
   (a) the sum originally due to such Lender or the Agent (as the case may be)
   in the specified currency and (b) any amounts shared with other Lenders as a
   result of allocations of such excess as a disproportionate payment to such
   Lender under SECTION 11.2, such Lender or the Agent (as the case may be)
   agrees to remit such excess to the Borrower................................28

   2.20.   NOTES; TELEPHONIC NOTICES. Each Lender shall, and is hereby
   authorized to, record the principal amount of each of its Loans and each
   repayment on the schedule attached to its Note (or to otherwise record the
   same in its usual practice) provided, however, that the failure to so record
   shall not affect the Borrower's obligations in respect of such Loans. The
   Borrower hereby authorizes the Lenders and the Agent to extend, convert or
   continue U.S. Dollar Advances (it being understood and agreed that Alternate
   Currency Borrowing Requests must be in writing or by facsimile) 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. 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......................................................29
   2.21.   INTEREST PAYMENT DATES; INTEREST AND FEE BASIS. Interest accrued on
   each Floating Rate Advance shall be payable on each Payment Date, commencing
   with the first such date to occur after the date hereof, on any date on which
   the Floating 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 Floating Rate Advance converted into a
   Eurodollar Advance or Quoted Rate Advance on a day other than a Payment Date
   shall be payable on the date of conversion. Interest accrued on each Fixed
   Rate Advance shall be payable on the last day of its applicable Interest
   Period, on any date on which the Fixed Rate Advance is prepaid, whether by
   acceleration or otherwise, and at maturity. Interest accrued on each Fixed
   Rate Advance having an Interest Period longer than three months shall also be
   payable on the last day of each three-month interval during such Interest
   Period. Interest and fees shall be calculated for actual days elapsed on the
   basis of a 360-day year. Interest shall be payable for the day an Advance is
   made but not for the day of any payment on the amount paid if payment is
   received prior to noon (local 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....29
   2.22.   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, Alternate Currency Borrowing Request, Continuation/Conversion Notice
   and repayment notice received by it hereunder. The Agent will notify each
   Lender of the interest 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 Reference Rate......................30
   2.23.   LENDING INSTALLATIONS. Each Lender may book its Loans at any one or
   more Lending Installations selected by such Lender and may change its Lending
   Installation(s) from time to time. All terms of this Agreement shall apply to
   any such Lending Installation and the Notes shall be deemed held by each
   Lender for the benefit of such Lending Installation(s). Each Lender may from
   time to time, by written or facsimile notice to the Agent and the Borrower,
   designate a new Lending Installation through which Loans (or Loans in a
   particular currency)

                                      - 6 -
<Page>

   will be made by it and for whose account Loan payments (or Loan payments in a
   particular currency) are to be made. The Agent may from time to time, by
   written or facsimile notice to the Borrower and each Lender, designate a new
   Lending Installation at which Advances (or Advances in a particular currency)
   will be made available to the Borrower and at which payments on the Advances
   (or payments on Advances in a particular currency) are to be made by the
   Borrower...................................................................30
   2.24.   NON-RECEIPT OF FUNDS BY THE AGENT. Unless the Borrower or a Lender,
   as the case may be, notifies the Agent prior to the date on which it is
   scheduled to make payment to the Agent of (i) in the case of a Lender, the
   proceeds of a Loan or (ii) in the case of the Borrower, a payment of
   principal, 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 (i) in
   the case of payment by a Lender, the Federal Funds Effective Rate for such
   day or (ii) in the case of payment by the Borrower, the interest rate
   applicable to the relevant Loan............................................30
   2.25.   WITHHOLDING TAX EXEMPTION. At least five Business Days prior to the
   first date on which interest or fees are payable hereunder for the account of
   any Lender, each Lender that is not incorporated under the laws of the United
   States of America, or a state thereof, agrees that it will deliver to each of
   the Borrower and the Agent two duly completed copies of United States
   Internal Revenue Service Form 1001 or 4224, certifying in either case that
   such Lender is entitled to receive payments under this Agreement and the
   Notes without deduction or withholding of any United States federal income
   taxes. Each Lender which so delivers a Form 1001 or 4224 further undertakes
   to deliver to each of the Borrower and the Agent two additional copies of
   such form (or a successor form) on or before the date that such form expires
   (currently, three successive calendar years for Form 1001 and one calendar
   year for Form 4224) or becomes obsolete or after the occurrence of any event
   requiring a change in the most recent forms so delivered by it, and such
   amendments thereto or extensions or renewals thereof as may be reasonably
   requested by the Borrower or the Agent, in each case certifying that such
   Lender is entitled to receive payments under this Agreement and the Notes
   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
   with respect to it and such Lender advises the Borrower and the Agent that it
   is not capable of receiving payments without any deduction or withholding of
   United States federal income tax...........................................31

   3.1.    YIELD PROTECTION. If any law or any governmental or
   quasi-governmental rule, regulation, policy, guideline or directive (whether
   or not having the force of law), or any interpretation thereof, or the
   compliance of any Lender therewith.........................................31
   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 (as defined below), then, within
   15 days of demand by such Lender, the Borrower shall pay such Lender the
   amount necessary to compensate for any shortfall in the rate of return on the
   portion ...................................................................32
   of such increased capital which such Lender determines is attributable to
   this Agreement, its Loans or its obligation to make Loans hereunder (after
   taking into account such Lender's policies as to capital adequacy). "CHANGE"
   means (i) any change after the date of this Agreement in the Risk-Based
   Capital Guidelines (as defined below) or (ii) any adoption of or change in
   any other law, governmental or quasi-governmental rule, regulation, policy,
   guideline, interpretation, or directive (whether or not having the force of
   law) after the date of this Agreement which affects the amount of capital
   required or expected to be maintained by any Lender or any Lending
   Installation or any corporation controlling any Lender. "RISK-BASED CAPITAL
   GUIDELINES" means (i) the risk-based capital guidelines in effect in the
   United States on the date of this Agreement, including transition rules, and
   (ii) the corresponding capital 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........................................32
   3.3.    AVAILABILITY OF EURODOLLAR ADVANCES. If (i) any Lender determines
   that maintenance of its Eurodollar Loans at a suitable Lending Installation
   would violate any applicable law, rule, regulation, or directive, whether or
   not having the force of law, (ii) the Required Lenders determine that
   deposits of a type and maturity appropriate to match fund Eurodollar Advances
   are not available or (iii) the Required Lenders determine that the interest
   rate applicable to a Eurodollar Advance does not accurately reflect the cost
   of making or maintaining such Eurodollar Advance, then the Agent shall
   suspend the availability of any new Eurodollar Advances (whether pursuant to
   SECTION 2.10 or 2.13)......................................................32
   3.4.    FUNDING INDEMNIFICATION. If any payment of a Fixed Rate Advance
   occurs on a date prior to the last day of the applicable Interest Period,
   whether because of acceleration, prepayment or otherwise, or a Fixed Rate
   Advance is not made on the date specified by the Borrower in its Borrowing
   Notice, Alternate Currency Borrowing Request or Continuation/Conversion
   Notice, as the case may be, as a consequence of any condition precedent to
   such Advance under SECTION 2.1 or ARTICLE IV not being satisfied or as a
   consequence of any failure by the Borrower to borrow such Advance when the
   same has been made available to it pursuant to SECTION 2.12, the Borrower
   will indemnify each Lender for any loss or cost in liquidating or employing
   deposits acquired to fund or maintain the Fixed Rate Advance and, provided
   that such Lender has taken such reasonable action, if any, not
   disadvantageous to it, to mitigate the same, any other loss or cost incurred
   by such Lender resulting therefrom.........................................32

   3.5.    LENDER STATEMENTS; SURVIVAL OF INDEMNITY. To the extent reasonably
   possible, each Lender shall designate an alternate Lending Installation with
   respect to its Fixed Rate Loans to reduce any liability of the Borrower to
   such Lender under SECTIONS 2.18, 3.1 and 3.2 or to avoid the unavailability
   of Eurodollar Advances under SECTION 3.3, so long as such designation is not
   disadvantageous to such Lender. Each Lender shall deliver a written statement
   of such Lender as to the amount due, if any, under SECTION 2.18, 3.1, 3.2 or
   3.4. Such written statement shall set forth in reasonable detail (and in
   accordance with Agreement Accounting Principles, where applicable) the
   calculations upon which such Lender determined such amount and shall be
   final, conclusive and binding on the Borrower in the absence of manifest
   error. Determination of amounts payable under such Sections in connection

   Adverse Effect. As of the date hereof, the United States income tax returns

   Revenue Service through the fiscal year ended 1992. No tax liens have been

   contained any material misstatement of fact or omitted to state a material
   fact or any fact necessary to make the statements contained therein not
   misleading.................................................................36
   5.11.   REGULATION U. Margin stock (as defined in Regulation U) constitutes

   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
   failure to comply would not reasonably be expected to have a Material Adverse
   Effect. Neither the Borrower nor any Subsidiary has received any notice to
   the effect that its operations are not in material compliance with any of the
   requirements of applicable federal, state and local environmental, health and
   safety statutes and regulations or the subject of any federal or state
   investigation evaluating whether any remedial action is needed to respond to

                                     - 11 -
<Page>

   below). Based on the foregoing review, the Borrower reasonably believes that
   the Year 2000 Issue, as it relates to the Borrower's computer applications,
   will not result in a Material Adverse Effect. "Year 2000 Issue" means, with
   respect to any Person, the ability or inability of all computer applications
   material to such Person's business and operations properly to perform
   date-sensitive functions for all dates before and after January 1, 2000. The
   Borrower is unable to determine the ultimate impact, if any, on the

   payable, or both, whereupon the Obligations shall become immediately due and
   payable, without presentment, demand, protest or further notice of any kind,
   all of which the Borrower hereby expressly waives. The Required Lenders agree
   to give the Borrower prompt subsequent notice of any termination or

<Page>

   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

     interests sold to each Participant. The Lenders agree to share with each
     Participant, and each Participant, by exercising the right of setoff

                                   THE CREDITS

     2.1.    THE ADVANCES. Subject to the terms of this Agreement, the Borrower
may borrow, repay and reborrow Advances at any time prior to or on the Revolving
Credit Termination Date. The Advances may be U.S. Dollar Advances made pursuant
to SECTION 2.1(a) or Alternate Currency Advances made pursuant to SECTION
2.1(b). No Advances may be requested or made subsequent to the Revolving Credit
Termination Date. Principal payments made after the Revolving Credit Termination
Date may not be reborrowed.

             (a)    COMMITMENTS TO MAKE U.S. DOLLAR ADVANCES. From and including
     the date of this Agreement and to and including the Revolving Credit
     Termination Date, the Lenders severally agree, on the terms and conditions
     set forth in this Agreement, to make U.S. Dollar Advances to the Borrower
     from time to time in amounts such that, upon giving effect to each such
     U.S. Dollar Advance, the aggregate principal Dollar Amount of all Advances
     then outstanding shall not exceed the Aggregate Commitment then in effect;
     PROVIDED, that no Quoted Rate Advance shall be made (i) on or after the
     Revolving Credit Termination Date and (ii) unless each of the Lenders in

     2.2.    EXTENSION OF REVOLVING CREDIT TERMINATION DATE. The initial
Revolving Credit Termination Date shall be May 27, 2001. The Borrower may, not
earlier than 180 days and not later than 60 days prior to each anniversary of
the Restatement Effective Date execute and deliver to the Agent (who shall
promptly forward a copy of the same to each of the Lenders) an Extension Letter
in substantially the form of EXHIBIT "B" hereto, with appropriate insertions,
requesting that the Revolving Credit Termination Date be extended for one year.
Such request for an extension of the Revolving Credit Termination Date shall
become effective if, and only if, each Lender shall, in its sole and absolute
discretion, execute such Extension Letter and return copies thereof to the Agent
and the Borrower prior to each such applicable anniversary of the Restatement
Effective Date.

     2.3.    MANDATORY PAYMENTS. The Borrower shall make the following mandatory
payments on the Advances:

             (a)    Each Alternate Currency Advance shall be repaid in full on
     the last day of its respective Transaction Rate Interest Period.

             (b)    Each Advance outstanding on the Revolving Credit Termination
     Date shall be repaid in full on the Revolving Credit Termination Date (it
     being understood and agreed that, subject to the terms and conditions of
     this Agreement, the Borrower shall be entitled to make a final borrowing of
     one or more U.S. Dollar Advances pursuant to SECTION 2.1(a) on the
     Revolving Credit Termination Date).

             (c)    If on the last day of any calendar month, it is determined
     by the Agent that the aggregate Dollar Amount of all outstanding Advances
     exceeds the Aggregate Commitment then in effect, the Borrower shall within
     three Business Days of demand by the Agent make a repayment (in U.S.
     Dollars) of the outstanding Advances in an amount which is at least
     sufficient to eliminate such excess.

             (d)    The Revolving Credit Termination Balance shall be payable in
     twenty (20) equal, consecutive quarterly installments, commencing on the
     first Payment Date following the Revolving Credit Termination Date.

             (e)    Any outstanding Advances and all other unpaid Obligations
     shall be paid in full by the Borrower on the Facility Termination Date.

     2.4.    FEES. The Borrower further agrees to pay to the Agent, for the
ratable benefit of the Lenders, the Facility Fee for the period from the date
hereof to and including the Revolving Credit Termination Date. The Facility Fee
shall be payable quarterly in advance on the Restatement Effective Date and on
each Payment Date thereafter. The obligations of the Borrower under this Section
2.4 shall survive the payment of the Advances and the termination of this
Agreement.

     2.5.    OPTIONAL REDUCTIONS IN AGGREGATE COMMITMENT. The Borrower may
permanently reduce the Aggregate Commitment in whole or in part ratably among
the Lenders in integral multiples of $1,000,000, upon at least 10 days' written
notice to the Agent, which notice shall

                                     - 21 -
<Page>

specify the amount of any such reduction, provided, however, that the amount of
the Aggregate Commitment may not be reduced below the aggregate principal Dollar
Amount of the outstanding Advances. All accrued interest and fees shall be
payable on the effective date of any termination of the obligations of the
Lenders to make Loans hereunder.

     2.6.    RATABLE LOANS. Each Advance hereunder shall consist of Loans made
from the several Lenders ratably according to their respective Percentages.

     2.7.    TYPES OF ADVANCES. The U.S. Dollar Advances may be Floating Rate
Advances, Eurodollar Advances or Quoted Rate Advances, or a combination thereof,
selected by the Borrower in accordance with SECTIONS 2.10 and 2.13. All
Alternate Currency Advances shall be Transaction Rate Advances selected by the
Borrower in accordance with SECTION 2.11.

     2.8.    MINIMUM AMOUNT OF EACH ADVANCE. Each Fixed Rate Advance shall be in
the minimum amount of $1,000,000 (and in multiples of $100,000 if in excess
thereof), and each Floating Rate Advance shall be in the minimum amount of
$500,000 (and in multiples of $100,000 if in excess thereof), provided, however,
that any Floating Rate Advance may be in the amount of the Aggregate Commitment.

     2.9.    OPTIONAL PRINCIPAL PAYMENTS. The Borrower may from time to time
pay, without penalty or premium, all outstanding Floating Rate Advances, or, in
a minimum aggregate amount of $1,000,000 or any integral multiple of $100,000 in
excess thereof, any portion of the outstanding Floating Rate Advances upon 5
days' prior notice to the Agent. Fixed Rate Advances may be paid prior to the
last day of the applicable Interest Period, subject to compliance with SECTION
3.4; PROVIDED, however, that Quoted Rate Advances may not be repaid prior to the
last day of their respective Interest Periods. Principal payments made after the
Revolving Credit Termination Date shall be applied to the principal installments
payable under SECTION 2.3(d) in the inverse order of maturity.

     2.10.   METHOD OF SELECTING TYPES AND INTEREST PERIODS FOR NEW U.S. DOLLAR
ADVANCES. The Borrower shall select the Type and, in the case of each Eurodollar
Advance or Quoted Rate Advance, the Interest Period applicable to each new
Advance from time to time. The Borrower shall give the Agent irrevocable notice
in substantially the form of EXHIBIT "C" hereto with appropriate insertions (a
"BORROWING NOTICE") not later than (a) 1:00 p.m. (Chicago time) at least (i) one
Business Day before the Borrowing Date of each Floating Rate Advance and (ii)
two Business Days before the Borrowing Date for each Eurodollar Advance and (b)
11:30 a.m. (Chicago time) on the Borrowing Date for each Quoted Rate Advance, in
each case specifying:

             (i)    the Borrowing Date of such Advance, which shall be a
                    Business Day, prior to or, in the case of a Eurodollar
                    Advance or Floating Rate Advance, on the Revolving Credit
                    Termination Date,

             (ii)   the aggregate amount of such Advance,

             (iii)  the Type of Advance selected, and

                                     - 22 -
<Page>

             (iv)   in the case of each Eurodollar Advance or Quoted Rate
                    Advance, the Interest Period applicable thereto.

In the case of any Quoted Rate Advance, the Agent shall promptly inform each
Lender of its receipt of such Borrowing Notice for a Quoted Rate Advance and of
the interest rate it proposes to quote the Borrower therefor. If any Lender
refuses to make the requested Quoted Rate Advance, such Quoted Rate Advance
shall not be made. The Agent shall telephonically notify the Borrower of the
Lenders' acceptance or refusal of such Borrowing Notice for a Quoted Rate
Advance and, if such Borrowing Notice has been accepted, the pricing of such
Quoted Rate Advance. The Borrower shall either accept or reject the Quoted Rate
Advance upon receipt of such notice.

     2.11.   METHOD OF REQUESTING ALTERNATE CURRENCY ADVANCES. The Borrower may
from time to time in accordance with this Section 2.11 request the Lenders to
make one or more Alternate Currency Advances. The Lenders shall have no
obligation to make any such Alternate Currency Advance so requested by the
Borrower. If, and only if, each of the Lenders in its sole and absolute
discretion agrees, in the manner provided for in this Section 2.11, to make its
respective Loan comprising any such Alternate Currency Advance, will such
Alternate Currency Advance be made.

     In order to request an Alternate Currency Advance, the Borrower shall give
the Agent a request in substantially the form of EXHIBIT "D" hereto with
appropriate insertions (an "Alternate Currency Borrowing Request"), which
request shall be irrevocable, not later than 10:00 a.m. (Chicago time) at least
five Business Days before the requested Borrowing Date for such Alternate
Currency Advance, specifying:

             (i)    the Borrowing Date, which shall be a Business Day prior to
                    the Revolving Credit Termination Date, of such Advance,

             (ii)   the aggregate amount of such Advance,

             (iii)  the Alternate Currency in which such Advance is to be
                    denominated,

             (iv)   the Transaction Rate for such Advance, and

             (v)    the Transaction Rate Interest Period for such Advance.

     Upon receipt of any such Alternate Currency Borrowing Request, the Agent
shall promptly forward copies thereof to each of the Lenders. The requested
Alternate Currency Advance will be made as requested if, and only if, each
Lender shall, in its sole and absolute discretion, execute and return a copy of
such Alternate Currency Borrowing Request to the Agent not later than 10:00 a.m.
(Chicago time) at least three Business Days before the requested Borrowing Date
for such Alternate Currency Advance. Upon such receipt of an executed copy of
such Alternate Currency Borrowing Request from each of the Lenders (which copy
may be a facsimile transmittal), the Agent shall promptly notify the Borrower
and each of the Lenders of such acceptance, and thereupon the Lenders shall be
jointly and severally committed to make the

                                     - 23 -
<Page>

requested Alternate Currency Advance, subject to the terms and conditions of
this Agreement. The making by the Lenders of any one or more Alternate Currency
Advances shall not constitute a consent by the Lenders to make any subsequent
Alternate Currency Advances, whether in the same or a different Alternate
Currency.

     2.12.   MAKING THE LOANS. Subject to SECTION 2.10, on each Borrowing Date,
each Lender shall make available its Loan or Loans comprising the Advance or
Advances to be made on such Borrowing Date (i) in the case of a Loan denominated
in U.S. Dollars, not later than noon (Chicago time), in immediately available
funds to the Agent at its address specified pursuant to Article XIII and (ii) in
the case of a Loan denominated in an Alternate Currency, not later than noon
(local time), in the city of the Agent's Lending Installation for such Alternate
Currency, in such funds as may then be customary for the settlement of
international transactions in such currency in the city of and at the address of
the Agent's Lending Installation for such currency. The Agent will make the
funds so received from the Lenders available to the Borrower at the Agent's
aforesaid address.

     2.13.   CONVERSION AND CONTINUATION OF OUTSTANDING U.S. DOLLAR ADVANCES.
Outstanding U.S. Dollar Advances may be continued as or converted into U.S.
Dollar Advances of the same or another Type as provided below in this Section
2.13; PROVIDED, that notwithstanding anything else in this Section 2.13 to the
contrary, (a) outstanding U.S. Dollar Advances may not be converted into
Alternate Currency Advances pursuant to this Section 2.13 and (b) outstanding
Alternate Currency Advances may not be continued or converted pursuant to this
Section 2.13, but must be repaid on or prior to the last day of their respective
Interest Periods pursuant to SECTION 2.3(a) and may only be reborrowed pursuant
to SECTIONS 2.1(b) and 2.11.

     Each Floating Rate Advance shall continue as Floating Rate Advance unless
and until such Floating Rate Advance is repaid pursuant to SECTION 2.9 or
converted into a Eurodollar Advance or Quoted Rate Advance pursuant to this
Section 2.13. Each Eurodollar Advance shall continue as a Eurodollar Advance
until the end of its respective Eurodollar Interest Period, at which time such
Eurodollar Advance shall automatically be converted into a Floating Rate Advance
unless the Borrower shall have given the Agent a Continuation/Conversion Notice
requesting that, at the end of such Eurodollar Interest Period, such Eurodollar
Advance be continued as a Eurodollar Advance for a new Eurodollar Interest
Period or converted into a Quoted Rate Advance. Each Quoted Rate Advance shall
continue as a Quoted Rate Advance until the end of its respective Quoted Rate
Interest Period, at which time such Quoted Rate Advance shall automatically be
converted into a Floating Rate Advance unless the Borrower shall have given the
Agent a Continuation/Conversion Notice requesting that, at the end of such
Quoted Rate Interest Period, such Quoted Rate Advance be continued as a Quoted
Rate Advance for a new Quoted Rate Interest Period or converted into a
Eurodollar Advance. Subject to the terms of SECTION 2.8, the Borrower may from
time to time elect to convert all or any part of any Floating Rate Advance into
a Eurodollar Advance or Quoted Rate Advance, to continue all or any part of any
Eurodollar Advance as a Eurodollar Advance for a new Eurodollar Interest Period,
to convert all or any part of any Eurodollar Advance into a Quoted Rate Advance,
to continue all or any part of any Quoted Rate Advance as a Quoted Rate Advance
for a new Quoted Rate Interest Period or to convert all or any part of any
Quoted Rate Advance into a

                                     - 24 -
<Page>

Eurodollar Advance; PROVIDED, that any such continuation or conversion of an
existing Eurodollar Advance or Quoted Rate Advance shall be made on, and only
on, the last day of its respective Interest Period. The Borrower shall give the
Agent irrevocable notice (a "CONTINUATION/CONVERSION NOTICE") of each
continuation or conversion of an outstanding U.S. Dollar Advance as or into (a)
a Eurodollar Advance not later than 1:00 p.m. (Chicago time) at least two
Business Days prior to the date of or (b) not later than 11:30 a.m. (Chicago
time) on the date of the requested continuation or conversion, specifying:

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

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

             (iii)  the amount and Interest Period applicable to each Eurodollar
                    Advance or Quoted Rate Advance which such U.S. Dollar
                    Advance is to be continued as or converted into.

Notwithstanding anything to the contrary contained in this Section 2.13, (a) no
U.S. Dollar Advance may be converted into or continued as a Eurodollar Advance
at any time within 30 days of the Facility Termination Date, (b) no U.S. Dollar
Advance may be continued as or converted into a Quoted Rate Advance (I) at any
time on or after the Revolving Credit Termination Date and (II) unless the
Borrower and each Lender have agreed upon a Quoted Rate for the applicable
Quoted Rate Interest Period in accordance with the procedures set forth in
SECTION 2.10 applicable to new Quoted Rate Advances and (c) except with the
consent of the Required Lenders, no U.S. Dollar Advance may be continued as or
converted into a Eurodollar Advance or Quoted Rate Advance at any time when any
Default or Unmatured Default has occurred and is continuing.

                                     - 25 -
<Page>

     2.14.   RESTRICTIONS ON INTEREST PERIODS. No Interest Period may extend
beyond a Payment Date on which principal of the Advances shall be payable unless
outstanding principal of Floating Rate Advances and Fixed Rate Advances with
Interest Periods ending prior to said Payment Date shall be at least equal to
the amount so payable. No Interest Period shall extend beyond the Facility
Termination Date. No more than 10 Interest Periods may be in effect at any one
time. No more than three Quoted Rate Interest Periods may be in effect at any
one time.

     2.15.   CHANGES IN INTEREST RATE, ETC. Changes in the rate of interest on
that portion of any Advance maintained as a Floating Rate Advance will take
effect simultaneously with each change in the Alternate Base Rate and each
change in the Applicable Margin applicable thereto. Each Fixed Rate Advance
shall bear interest from and including the first day of the Interest Period
applicable thereto to but excluding the last day of such Interest Period at the
interest rate determined as applicable to such Fixed Rate Advance, provided that
the rate of interest on each Eurodollar Advance will change simultaneously with
each change, during the applicable Eurodollar Interest Period, of the Applicable
Margin.

     2.16.   RATES APPLICABLE AFTER DEFAULT. 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 (i) each Fixed Rate Advance shall bear interest
for the remainder of the applicable Interest Period at the rate otherwise
applicable to such Interest Period plus 2% per annum and (ii) each Floating Rate
Advance shall bear interest at a rate per annum equal to the Floating Rate
otherwise applicable to the Floating Rate Advance plus 2% per annum.

     2.17.   METHOD OF PAYMENT. (a) All payments of principal, interest and fees
to be made by the Borrower hereunder or under the Notes in U.S. Dollars 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 (local time) on the date 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 which the Agent received at such Lender's
address specified pursuant to ARTICLE XIII or at any Lending Installation
specified in a notice received by the Agent from such Lender.

     (b)     Each Advance shall be repaid or prepaid in the currency in which it
was made in the amount borrowed and interest payable thereon shall be paid in
such currency. All payments to be made by the Borrower hereunder or under the
Notes in any Alternate Currency shall be made in such Alternate Currency on the
date due in such funds as may then be customary for the settlement of
international transactions in such Alternate Currency for the account of the
Agent, at its Lending Installation for such Alternate Currency. The Agent will
promptly cause such payments to be distributed to each Lender in like funds and
currency at such Lender's address specified pursuant to ARTICLE XIII or at any
Lending Installation specified in a notice received by the Agent from such
Lender. Notwithstanding the foregoing provisions of this Section, if, after the
making of any Advance in any Alternate Currency, currency control or exchange
regulations

                                     - 26 -
<Page>

are imposed in the country which issues such Alternate Currency with the result
that different types of such Alternate Currency (the "New Currency") are
introduced and the type of Alternate Currency in which the Advance was made (the
"Original Currency") no longer exists or the Borrower is not able to make
payment to the Agent for the account of the Lenders in such Original Currency,
then all payments to be made by the Borrower hereunder or under the Notes in
such Alternate Currency shall be made in such amount and such type of the New
Currency as shall be equivalent to the amount of such payment otherwise due
hereunder or under the Notes in the Original Currency, it being the intention of
the Borrower and the Lenders that the Borrower take all risks of the imposition
of any such currency control or exchange regulations.

     (c)     On or before the time a principal payment is made on any of the
Advances, the Borrower shall inform the Agent as to the proportionate
application of such payment among the Floating Rate Advances, the Eurodollar
Advances, the Quoted Rate Advances and the Alternate Currency Advances. In the
absence of such instructions, the Agent shall apply such payment first to the
outstanding Floating Rate Advances and then apply any remainder to the
outstanding Eurodollar Advances, Quoted Rate Advances and Alternate Currency
Advances in whatever proportion it shall determine in its sole discretion;
PROVIDED, that as between Eurodollar Advances, as between Quoted Rate Advances
and as between Alternate Currency Advances of the same Alternate Currency, the
Agent shall endeavor to make such application (not otherwise disadvantageous to
the Agent or the Lenders) as will mitigate the Borrower's liability to the
Lenders under SECTION 3.4 as a consequence of such application.

     2.18.   FOREIGN TAXES. (a) All payments made by the Borrower in respect of
principal of and interest on the Advances and of all other amounts payable by it
under this Agreement are payable without deduction for or on account of any
present or future taxes, duties, withholdings or other charges levied or imposed
by the government of any jurisdiction outside the United States of America or by
any political subdivision or taxing authority thereof or therein (herein called
"FOREIGN TAXES"). If the Borrower shall be required by law to deduct or withhold
any Foreign Taxes from any such amount payable by it hereunder or under any of
the Notes to or for the account of any Lender, (i) such amount shall be
increased as may be necessary so that, after making such deductions or
withholdings (including any deductions or withholdings applicable to additional
amounts payable pursuant to this Section), such Lender receives an amount equal
to the amount it would have received had no such deductions or withholdings been
made and (ii) the Borrower shall make such deductions and withholdings and pay
the amount thereof to the relevant government, political subdivision or taxing
authority at or prior to the time required to be paid under applicable law (and
shall promptly furnish to the Agent, for the benefit of the Lenders, official
receipts evidencing such payment). In addition, the Borrower will pay any
present or future stamp or documentary taxes or similar taxes or levies imposed
by any government, political subdivision or taxing authority referred to in the
first sentence of this subsection arising from any payment by it hereunder or
under any of the Notes or from the execution, delivery or registration of, or
otherwise with respect to, this Agreement or any of the Notes (herein called
"OTHER TAXES"). The Borrower will indemnify each Lender and the Agent for, and
hold each Lender and the Agent harmless against, the full amount of Foreign
Taxes or Other Taxes (including, without limitation, any Foreign Taxes or Other
Taxes imposed by any jurisdiction on amounts payable under this Section) paid or
payable by such Lender or the Agent

                                     - 27 -
<Page>

and any liability of such Lender or the Agent relating thereto (including,
without limitation, penalties, interest and expenses).

     (b)     If the cost to any Lender of making or maintaining any Loan to the
Borrower is increased, or the amount of any sum received or receivable by any
Lender (or its applicable Lending Installation) is reduced, by an amount deemed
by such Lender to be material, which increase or reduction (i) is due to any law
or any governmental or quasi-governmental rule, regulation, policy, guideline or
directive (whether or not having the force of law), or any interpretation
thereof, or the compliance of any Lender therewith, and (ii) would not have
occurred but for the fact that the Borrower (or one or more of its Subsidiaries)
conducts business in a jurisdiction outside the United States of America, the
Borrower shall indemnify such Lender for such increased cost or reduction within
15 days after demand by such Lender (with a copy to the Agent).

     (c)     If, and to the extent that, any Lender shall actually receive a
credit against its United States federal income tax liability for any Foreign
Taxes or Other Taxes indemnified or paid by the Borrower pursuant to this
Section, such Lender agrees to promptly notify the Borrower thereof and make
reimbursement of such credit to the Borrower, provided that if such Lender
reasonably believes that such credit may be subject to challenge, then such
Lender shall thereupon enter into negotiations in good faith with the Borrower
to determine when reimbursement of such credit can be made to the Borrower.

     (d)     All tax receipts required to be delivered under this Section shall
be originals, duplicate originals or duly certified or authenticated copies
within the meaning of Treasury Regulation Section 1.905-2(a)(2).

     2.19.   JUDGMENT CURRENCY. If for the purposes of obtaining judgment in any
court it is necessary to convert a sum due from the Borrower hereunder or under
any of the Notes in the currency expressed to be payable herein or under the
Notes (the "SPECIFIED CURRENCY") into another currency, the parties hereto
agree, to the fullest extent that they may effectively do so, that the rate of
exchange used shall be that at which in accordance with normal banking
procedures the Agent could purchase the specified currency with such other
currency at the Agent's main Chicago office on the Business Day preceding that
on which final, nonappealable judgment is given. The obligations of the Borrower
in respect of any sum due to any Lender or the Agent hereunder or under any Note
shall, notwithstanding any judgment in a currency other than the specified
currency, be discharged only to the extent that on the Business Day following
receipt by such Lender or the Agent (as the case may be) of any sum adjudged to
be so due in such other currency such Lender or the Agent (as the case may be)
may in accordance with normal, reasonable banking procedures purchase the
specified currency with such other currency. If the amount of the specified
currency so purchased is less than the sum originally due to such Lender or the
Agent (as the case may be), in the specified currency, the Borrower agrees, to
the fullest extent that it may effectively do so, as a separate obligation and
notwithstanding any such judgment, to indemnify such Lender or the Agent (as the
case may be) against such loss, and if the amount of the specified currency so
purchased exceeds (a) the sum originally due to such Lender or the Agent (as the
case may be) in the specified currency and (b)

                                     - 28 -
<Page>

any amounts shared with other Lenders as a result of allocations of such excess
as a disproportionate payment to such Lender under SECTION 11.2, such Lender or
the Agent (as the case may be) agrees to remit such excess to the Borrower.

     2.20.   NOTES; TELEPHONIC NOTICES. Each Lender shall, and is hereby
authorized to, record the principal amount of each of its Loans and each
repayment on the schedule attached to its Note (or to otherwise record the same
in its usual practice) provided, however, that the failure to so record shall
not affect the Borrower's obligations in respect of such Loans. The Borrower
hereby authorizes the Lenders and the Agent to extend, convert or continue U.S.
Dollar Advances (it being understood and agreed that Alternate Currency
Borrowing Requests must be in writing or by facsimile) 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. 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.

     Upon receipt of its Note, each Lender will: (i) record the aggregate unpaid
principal amount of the note dated September 9, 1996 (the "Original Note")
issued under the Original Agreement in its records or, at its option, on the
schedule attached to the Note as the aggregate unpaid principal amount of the
Note; (ii) mark the Original Note as replaced by the Note; and (iii) promptly
return the Original Note to the Borrower. Thereafter, all references in this
Agreement and any and all instruments or documents provided for herein or
delivered or to be delivered hereunder or in connection herewith to the Original
Note shall be deemed references to the Note. The replacement of the Original
Note with the Note shall not be construed to deem paid or forgiven the unpaid
principal amount of, or unpaid accrued interest on, the Original Note
outstanding at the time of replacement.

     2.21.   INTEREST PAYMENT DATES; INTEREST AND FEE BASIS. Interest accrued on
each Floating Rate Advance shall be payable on each Payment Date, commencing
with the first such date to occur after the date hereof, on any date on which
the Floating 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 Floating Rate Advance converted into a Eurodollar Advance or
Quoted Rate Advance on a day other than a Payment Date shall be payable on the
date of conversion. Interest accrued on each Fixed Rate Advance shall be payable
on the last day of its applicable Interest Period, on any date on which the
Fixed Rate Advance is prepaid, whether by acceleration or otherwise, and at
maturity. Interest accrued on each Fixed Rate Advance having an Interest Period
longer than three months shall also be payable on the last day of each
three-month interval during such Interest Period. Interest and fees shall be
calculated for actual days elapsed on the basis of a 360-day year. Interest
shall be payable for the day an Advance is made but not for the day of any
payment on the amount paid if payment is received prior to noon (local 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

                                     - 29 -
<Page>

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.

     2.22.   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, Alternate Currency Borrowing Request, Continuation/Conversion
Notice and repayment notice received by it hereunder. The Agent will notify each
Lender of the interest 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 Reference Rate.

     2.23.   LENDING INSTALLATIONS. Each Lender may book its Loans at any one or
more Lending Installations selected by such Lender and may change its Lending
Installation(s) from time to time. All terms of this Agreement shall apply to
any such Lending Installation and the Notes shall be deemed held by each Lender
for the benefit of such Lending Installation(s). Each Lender may from time to
time, by written or facsimile notice to the Agent and the Borrower, designate a
new Lending Installation through which Loans (or Loans in a particular currency)
will be made by it and for whose account Loan payments (or Loan payments in a
particular currency) are to be made. The Agent may from time to time, by written
or facsimile notice to the Borrower and each Lender, designate a new Lending
Installation at which Advances (or Advances in a particular currency) will be
made available to the Borrower and at which payments on the Advances (or
payments on Advances in a particular currency) are to be made by the Borrower.

     2.24.   NON-RECEIPT OF FUNDS BY THE AGENT. Unless the Borrower or a Lender,
as the case may be, notifies the Agent prior to the date on which it is
scheduled to make payment to the Agent of (i) in the case of a Lender, the
proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal,
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 (i) in the case of payment by a Lender, the
Federal Funds Effective Rate for such day or (ii) in the case of payment by the
Borrower, the interest rate applicable to the relevant Loan.

     2.25.   WITHHOLDING TAX EXEMPTION. At least five Business Days prior to the
first date on which interest or fees are payable hereunder for the account of
any Lender, each Lender that is not incorporated under the laws of the United
States of America, or a state thereof, agrees that it will deliver to each of
the Borrower and the Agent two duly completed copies of United States Internal
Revenue Service Form 1001 or 4224, certifying in either case that such Lender is
entitled to receive payments under this Agreement and the Notes without
deduction or withholding of any United States federal income taxes. Each Lender
which so delivers a Form

                                     - 30 -
<Page>

1001 or 4224 further undertakes to deliver to each of the Borrower and the Agent
two additional copies of such form (or a successor form) on or before the date
that such form expires (currently, three successive calendar years for Form 1001
and one calendar year for Form 4224) or becomes obsolete or after the occurrence
of any event requiring a change in the most recent forms so delivered by it, and
such amendments thereto or extensions or renewals thereof as may be reasonably
requested by the Borrower or the Agent, in each case certifying that such Lender
is entitled to receive payments under this Agreement and the Notes 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 with respect to it and
such Lender advises the Borrower and the Agent that it is not capable of
receiving payments without any deduction or withholding of United States federal
income tax.

                                   ARTICLE III

                             CHANGE IN CIRCUMSTANCES

     3.1.    YIELD PROTECTION. If any law or any governmental or
quasi-governmental rule, regulation, policy, guideline or directive (whether or
not having the force of law), or any interpretation thereof, or the compliance
of any Lender therewith,

             (i)    subjects any Lender or any applicable Lending Installation
     to any tax, duty, charge or withholding on or from payments due from the
     Borrower (excluding federal taxation of the overall net income of any
     Lender or applicable Lending Installation), or changes the basis of
     taxation of payments to any Lender in respect of its Loans or other amounts
     due it hereunder, or

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

             (iii)  imposes any other condition the result of which is to
     increase the cost to any Lender or any applicable Lending Installation of
     making, funding or maintaining loans or reduce any amount receivable by any
     Lender or any applicable Lending Installation in connection with loans, or
     requires any Lender or any applicable Lending Installation to make any
     payment calculated by reference to the amount of loans held or interest
     received by it, by an amount deemed material by such Lender,

then, within 15 days of demand by such Lender, the Borrower shall pay such
Lender that portion of such increased expense incurred or reduction in an amount
received which such Lender determines is attributable to making, funding and
maintaining its Loans and its Commitment.

                                     - 31 -
<Page>

     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 (as defined below), then, within 15 days of
demand by such Lender, the Borrower shall pay such Lender the amount necessary
to compensate for any shortfall in the rate of return on the portion of such
increased capital which such Lender determines is attributable to this
Agreement, its Loans or its obligation to make Loans hereunder (after taking
into account such Lender's policies as to capital adequacy). "CHANGE" means (i)
any change after the date of this Agreement in the Risk-Based Capital Guidelines
(as defined below) or (ii) any adoption of or change in any other law,
governmental or quasi-governmental rule, regulation, policy, guideline,
interpretation, or directive (whether or not having the force of law) after the
date of this Agreement which affects the amount of capital required or expected
to be maintained by any Lender or any Lending Installation or any corporation
controlling any Lender. "RISK-BASED CAPITAL GUIDELINES" means (i) the risk-based
capital guidelines in effect in the United States on the date of this Agreement,
including transition rules, and (ii) the corresponding capital 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 EURODOLLAR ADVANCES. If (i) any Lender determines
that maintenance of its Eurodollar Loans at a suitable Lending Installation
would violate any applicable law, rule, regulation, or directive, whether or not
having the force of law, (ii) the Required Lenders determine that deposits of a
type and maturity appropriate to match fund Eurodollar Advances are not
available or (iii) the Required Lenders determine that the interest rate
applicable to a Eurodollar Advance does not accurately reflect the cost of
making or maintaining such Eurodollar Advance, then the Agent shall suspend the
availability of any new Eurodollar Advances (whether pursuant to SECTION 2.10 or
2.13).

     3.4.    FUNDING INDEMNIFICATION. If any payment of a Fixed Rate Advance
occurs on a date prior to the last day of the applicable Interest Period,
whether because of acceleration, prepayment or otherwise, or a Fixed Rate
Advance is not made on the date specified by the Borrower in its Borrowing
Notice, Alternate Currency Borrowing Request or Continuation/Conversion Notice,
as the case may be, as a consequence of any condition precedent to such Advance
under SECTION 2.1 or ARTICLE IV not being satisfied or as a consequence of any
failure by the Borrower to borrow such Advance when the same has been made
available to it pursuant to SECTION 2.12, the Borrower will indemnify each
Lender for any loss or cost in liquidating or employing deposits acquired to
fund or maintain the Fixed Rate Advance and, provided that such Lender has taken
such reasonable action, if any, not disadvantageous to it, to mitigate the same,
any other loss or cost incurred by such Lender resulting therefrom.

     3.5.    LENDER STATEMENTS; SURVIVAL OF INDEMNITY. To the extent reasonably
possible, each Lender shall designate an alternate Lending Installation with
respect to its Fixed Rate Loans to reduce any liability of the Borrower to such
Lender under SECTIONS 2.18, 3.1 and 3.2 or to

                                     - 32 -
<Page>

avoid the unavailability of Eurodollar Advances under SECTION 3.3, so long as
such designation is not disadvantageous to such Lender. Each Lender shall
deliver a written statement of such Lender as to the amount due, if any, under
SECTION 2.18, 3.1, 3.2 or 3.4. Such written statement shall set forth in
reasonable detail (and in accordance with Agreement Accounting Principles, where
applicable) the calculations upon which such Lender determined such amount and
shall be final, conclusive and binding on the Borrower in the absence of
manifest error. Determination of amounts payable under such Sections in
connection with a Eurodollar Loan shall be calculated as though each Lender
funded its Eurodollar Loan through the purchase of a deposit of the type and
maturity corresponding to the deposit used as a reference in determining the
Eurodollar Rate applicable to such Eurodollar Loan, whether in fact that is the
case or not. Unless otherwise provided herein, the amount specified in the
written statement shall be payable on demand after receipt by the Borrower of
the written statement. The obligations of the Borrower under SECTIONS 2.18, 3.1,
3.2 and 3.4 shall survive payment of the obligations and termination of this
Agreement.

     3.6.    REFUND TO BORROWER. If, and to the extent that, any Lender shall
actually receive a credit against its United States federal income tax liability
or otherwise receive any rebate or refund from any government or governmental
agency in respect of any amount paid by the Borrower pursuant to SECTION 3.1 or
3.2, such Lender agrees to promptly notify the Borrower thereof and make
reimbursement of credit, rebate or refund to the Borrower, provided that if such
Lender reasonably believes that such credit, rebate or refund may be subject to
challenge, then such Lender shall thereupon enter into negotiations in good
faith with the Borrower to determine when reimbursement of such credit, rebate
or refund can be made to the Borrower.

                                   ARTICLE IV

                              CONDITIONS PRECEDENT

     4.1.    CONDITIONS PRECEDENT TO THE RESTATEMENT EFFECTIVE DATE. This
Agreement shall become effective on the date (the "Restatement Effective Date")
on which the Borrower shall have furnished to the Agent, with sufficient copies
for the Lenders:

      (i)    Copies, certified by the Secretary or Assistant Secretary of the
             Borrower, of its Board of Directors' resolutions (and resolutions
             of other bodies, if any are deemed necessary by counsel for any
             Lender) authorizing the execution of the Loan Documents.

     (ii)    An incumbency certificate, executed 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 Lenders shall be entitled to rely until
             informed of any change in writing by the Borrower.

                                     - 33 -
<Page>

    (iii)    A certificate, signed by the chief financial officer of the
             Borrower stating that on the Restatement Effective Date no Default
             or Unmatured Default has occurred and is continuing.

     (iv)    A written opinion of the Borrower's counsel, addressed to the
             Lenders in substantially the form of EXHIBIT "E" hereto.

      (v)    Note payable to the order of each of the Lenders.

     (vi)    Such other documents as any Lender or its counsel may have
             reasonably requested.

     4.2.    EACH ADVANCE.  The Lenders shall not be required to make any
Advance, unless on the applicable Borrowing Date:

      (i)    There exists no Default or Unmatured Default.

     (ii)    The representations and warranties contained in ARTICLE V are true
             and correct as of such Borrowing Date except for changes in the
             Schedules hereto reflecting transactions permitted by this
             Agreement.

    (iii)    If such Advance is a U.S. Dollar Advance, the Agent shall have
             received a duly completed Borrowing Notice from the Borrower
             pursuant to SECTION 2.10 and, in the case of any Quoted Rate
             Advance, such Borrowing Notice shall have been accepted by the
             Lenders pursuant to SECTION 2.10.

     (iv)    If such Advance is an Alternate Currency Advance, the Agent shall
             have received a duly completed Alternate Currency Borrowing Request
             from the Borrower pursuant to SECTION 2.11, and such Alternate
             Currency Borrowing Request shall have been agreed to in writing by
             each of the Lenders pursuant to SECTION 2.11.

      (v)    All legal matters incident to the making of such Advance shall be
             in accordance with this Agreement in the reasonable judgment of the
             Lenders and their counsel.

     Each Borrowing Notice or Alternate Currency Borrowing Request with respect
to each such Advance shall constitute a representation and warranty by the
Borrower that the conditions contained in paragraphs (i) and (ii) above and have
been satisfied. Any Lender may require a duly completed compliance certificate
in substantially the form of EXHIBIT "G" hereto as a condition to making an
Advance.

                                    ARTICLE V

                         REPRESENTATIONS AND WARRANTIES

     The Borrower represents and warrants to the Lenders that:

                                     - 34 -
<Page>

     5.1.    CORPORATE EXISTENCE AND STANDING. Each of the Borrower and its
Subsidiaries is a corporation duly incorporated, validly existing and in good
standing under the laws of its jurisdiction of incorporation and has all
requisite authority to conduct its business in each jurisdiction in which its
business is conducted.

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

     5.3.    NO CONFLICT; GOVERNMENT CONSENT. Neither the execution and delivery
by the Borrower of the Loan Documents, nor the consummation of the transactions
therein contemplated, nor compliance with the provisions thereof will violate
any law, rule, regulation, order, writ, judgment, injunction, decree or award
binding on the Borrower or any of its Subsidiaries or the Borrower's or any
Subsidiary's articles of incorporation or by-laws or the provisions of any
indenture, instrument or agreement to which the Borrower or any of its
Subsidiaries is a party or is subject, or by which it, or its property, is
bound, or conflict with or constitute a default thereunder, or result in the
creation or imposition of any Lien in, of or on the property of the Borrower or
a Subsidiary pursuant to the terms of any such indenture, instrument or
agreement. No order, consent, approval, license, authorization, or validation
of, or filing, recording or registration with, or exemption by, any governmental
or public body or authority, or any subdivision thereof, is required to
authorize, or is required in connection with the execution, delivery and
performance of, or the legality, validity, binding effect or enforceability of,
any of the Loan Documents.

     5.4.    FINANCIAL STATEMENTS. The May 31, 1997 consolidated financial
statements of the Borrower and its Subsidiaries heretofore delivered to the
Lenders were prepared in accordance with generally accepted accounting
principles in effect on the date such statements were prepared and fairly
present the consolidated financial condition and operations of the Borrower and
its Subsidiaries at such date and the consolidated results of their operations
for the period then ended.

     5.5.    MATERIAL ADVERSE CHANGE. Since May 31, 1997, there has been no
change in the business, properties, prospects, condition (financial or
otherwise) or results of operations of the Borrower and its Subsidiaries which
could reasonably be expected to have a Material Adverse Effect.

     5.6.    TAXES. The Borrower and its Subsidiaries have filed all United
States federal tax returns and all other tax returns which are required to be
filed and have paid all taxes due pursuant to said returns or pursuant to any
assessment received by the Borrower or any of its Subsidiaries, except for the
filing of such returns and the payment of such taxes, if any, as (a) are

                                     - 35 -
<Page>

being contested in good faith and as to which adequate reserves have been
provided or (b) do not in the aggregate exceed $4,000,000 and the failure to
file or pay for which could not reasonably be expected to have a Material
Adverse Effect. As of the date hereof, the United States income tax returns of
the Borrower and its Subsidiaries have been audited by the Internal Revenue
Service through the fiscal year ended 1992. No tax liens have been filed other
than those permitted pursuant to SECTION 6.16(a). The charges, accruals and
reserves on the books of the Borrower and its Subsidiaries in respect of any
taxes or other governmental charges are adequate.

     5.7.    LITIGATION AND CONTINGENT OBLIGATIONS. Except as set forth in the
Borrower's Form 10-K filed with the Securities and Exchange Commission for its
fiscal year ended May 31, 1997, there is no litigation, arbitration,
governmental investigation, proceeding or inquiry pending or, to the knowledge
of any of their officers, threatened against or affecting the Borrower or any of
its Subsidiaries which could reasonably be expected to have a Material Adverse
Effect. Other than any liability incident to such litigation, arbitration or
proceedings, the Borrower has no material contingent obligations not provided
for or disclosed in the Borrower's Form 10-K filed with the Securities and
Exchange Commission for its fiscal year ended May 31, 1997.

     5.8.    SUBSIDIARIES. As of the date hereof, Borrower's Form 10-K filed
with the Securities and Exchange Commission for its fiscal year ended May 31,
1997 contains an accurate description of all of the Borrower's presently
existing Significant Subsidiaries (as defined in Regulation S-X of the
Securities and Exchange Commission). All of the issued and outstanding shares of
capital stock of all of the Borrower's Subsidiaries have been duly authorized
and issued and are fully paid and non-assessable.

     5.9.    ERISA. The Unfunded Liabilities of all Single Employer Plans do not
in the aggregate exceed $10,000,000. Neither the Borrower nor any other member
of the Controlled Group has incurred, or is reasonably expected to incur any
withdrawal liability to Multiemployer Plans in an aggregate amount which, when
added to the aggregate Unfunded Liabilities of all Single Employer Plans, would
exceed of $10,000,000. Each Plan complies in all material respects with all
applicable requirements of law and regulations and no Reportable Event has
occurred with respect to any Plan. Neither the Borrower nor any other member of
the Controlled Group has withdrawn from any Plan or initiated steps to do so,
and no steps have been taken to reorganize or terminate any Plan.

     5.10.   ACCURACY OF INFORMATION. No information, exhibit or report
furnished by the Borrower or any of its Subsidiaries to the Agent or any Lender
in connection with the negotiation of, or compliance with, the Loan Documents
contained any material misstatement of fact or omitted to state a material fact
or any fact necessary to make the statements contained therein not misleading.

     5.11.   REGULATION U. Margin stock (as defined in Regulation U) 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.

                                     - 36 -
<Page>

     5.12.   COMPLIANCE WITH LAWS. The Borrower and its Subsidiaries have
complied in all 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 failure to comply would not reasonably be expected to have a Material
Adverse Effect. Neither the Borrower nor any Subsidiary has received any notice
to the effect that its operations are not in material compliance with any of the
requirements of applicable federal, state and local environmental, health and
safety statutes and regulations or the subject of any federal or state
investigation evaluating whether any remedial action is needed to respond to a
release of any toxic or hazardous waste or substance into the environment, which
non-compliance or remedial action could reasonably be expected to have a
Material Adverse Effect.

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

     5.14.   YEAR 2000 COMPLIANCE. The Borrower has conducted a comprehensive
review and assessment of its computer applications and is in the process of
making inquiry of its material suppliers, vendors and customers with respect to
the Year 2000 Issue (as such term is defined below). Based on the foregoing
review, the Borrower reasonably believes that the Year 2000 Issue, as it relates
to the Borrower's computer applications, will not result in a Material Adverse
Effect. "Year 2000 Issue" means, with respect to any Person, the ability or
inability of all computer applications material to such Person's business and
operations properly to perform date-sensitive functions for all dates before and
after January 1, 2000. The Borrower is unable to determine the ultimate impact,

                                  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 may terminate
or suspend the obligations of the Lenders to make Loans hereunder, or by written
notice to the Borrower declare the Obligations to be due and payable, or both,
whereupon the Obligations shall become immediately due and payable, without
presentment, demand, protest or further notice of any kind, all of which the
Borrower hereby expressly waives. The Required Lenders agree to give the
Borrower prompt subsequent notice of any termination or suspension of the
obligations of the Lenders to make Loans hereunder; PROVIDED, that the giving of
such notice shall not be a condition to the effectiveness of any such
termination or suspension.

     If, within 30 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
(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 waiving any
Default hereunder; provided, however, that no such supplemental agreement shall,
without the consent of each Lender affected thereby:

               (i)  Extend the maturity of any Loan or Note or reduce the
                    principal amount thereof, or reduce the rate or extend the
                    time of payment of interest or fees thereon.

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

             (iii)  Extend the Revolving Credit Termination Date, or reduce the
                    amount or extend the payment date for, the mandatory
                    payments required under SECTION 2.3, or increase the amount
                    of the Commitment of any Lender hereunder, or permit the
                    Borrower to assign its rights under this Agreement.

              (iv)  Amend this Section 8.2.

                                     - 51 -
<Page>

               (v)  Release any guarantor of any Advance or release all or
                    substantially all of any collateral, if any, supporting the
                    Obligations.

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

     8.3.    PRESERVATION OF RIGHTS. No delay or omission of the Lenders or the
Agent to exercise any right under the 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.

the contrary notwithstanding, no Lender shall be obligated to extend credit to

obligations hereunder. This Agreement shall not be construed so as to confer any
right or benefit upon any Person other than the parties to this Agreement and
their respective successors and assigns.

     9.7.    EXPENSES; INDEMNIFICATION. The Borrower shall reimburse the Agent

paid or incurred by the Agent or any Lender in connection with the collection
and enforcement of the Loan Documents. The Borrower further agrees to indemnify
the Agent and each Lender, its 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 or any Lender is a party thereto) which any of
them may pay or incur arising out of any term or condition contained in this
Agreement or the other Loan Documents, or the direct or indirect application or
proposed application of the proceeds of any Loan hereunder, except to the extent
any of the foregoing arises solely from the gross negligence or wilful
misconduct of the party requesting indemnification. The obligations of the
Borrower under this Section shall survive the termination of this Agreement.

     9.8.    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.

enforceability, or validity of that provision in any other jurisdiction, and to

     9.11.   NONLIABILITY OF LENDERS. The relationship between the Borrower and

     9.13.   CONSENT TO JURISDICTION. THE BORROWER, THE AGENT AND EACH LENDER
HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED

PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER,

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 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.

     10.11.  SUCCESSOR AGENT. The Agent may resign at any time by giving written
notice thereof to the Lenders and the Borrower, and the Agent may be removed at
any time with or without cause by written notice received by the Agent from the
Required Lenders. Upon any such resignation or removal, the Required Lenders
shall have the right to appoint, on behalf of

                                     - 56 -
<Page>

the Borrower and the Lenders, a successor Agent. If no successor Agent shall
have been so appointed by the Required Lenders and shall have accepted such
appointment within 30 days after the retiring Agent's giving notice of
resignation, then the retiring Agent may appoint, on behalf of the Borrower and
the Lenders, a successor Agent. 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 retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder and under
the other Loan Documents. After any retiring Agent's resignation hereunder as
Agent, the provisions of this Article X shall continue in effect for its benefit
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.

                                   ARTICLE XI

                            SETOFF; RATABLE PAYMENTS

     11.1.   SETOFF. In addition to, and without limitation of, any rights of
the Lenders under applicable law, so long as any Default has occurred and is
continuing, any indebtedness from any Lender to the Borrower (including all
account balances, whether provisional or final and whether or not collected or
available) may be offset and applied toward the payment of the Obligations then
due and owing to such Lender.

     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
SECTIONS 2.18, 3.1, 3.2 or 3.4) 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 Percentage 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
according to their respective Percentages. In case any such payment is disturbed
by legal process, or otherwise, appropriate further adjustments shall be made.

                                   ARTICLE XII

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

     12.1.   SUCCESSORS AND ASSIGNS. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns, except that (i) the
Borrower shall not have the right to assign its rights or

                                     - 57 -
<Page>

obligations under the Loan Documents and (ii) any assignment by any Lender must
be made in compliance with SECTION 12.3. Notwithstanding CLAUSE (ii) of this
Section, any Lender may at any time, without the consent of the Borrower or the
Agent, assign all or any portion of its rights under this Agreement and its
Notes to a Federal Reserve Bank; provided, however, that no such assignment
shall release the transferor Lender from its obligations hereunder. The Agent
may treat the payee of any Note as the owner thereof for all purposes hereof
unless and until such payee complies with SECTION 12.3 in the case of an
assignment thereof or, in the case of any other transfer, a written notice of
the transfer is filed with the Agent. Any assignee or transferee of a Note
agrees by acceptance thereof to be bound by all the terms and provisions of the
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 holder of any
Note, shall be conclusive and binding on any subsequent holder, transferee or
assignee of such Note or of any Note or Notes issued in exchange therefor.

     12.2.   PARTICIPATIONS.

             12.2.1. PERMITTED PARTICIPANTS; EFFECT. Any Lender may, in the
     ordinary course of its business and in accordance with applicable law, at
     any time sell to one or more banks or other entities ("PARTICIPANTS")
     participating interests in any Loan owing to such Lender, any Note held by
     such Lender, any Commitment of such Lender or any other interest of such
     Lender under the Loan Documents. Any Lender selling such participating
     interests to a Participant agrees to promptly notify the Borrower of such
     sale and the identity of such Participant. 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 holder of any
     such Note 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.

             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 forgives
     principal, interest or fees or reduces the interest rate or fees payable
     with respect to any such Loan or Commitment, postpones any date fixed for
     any regularly-scheduled payment of principal of, or interest or fees on,
     any such Loan or Commitment, releases any guarantor of any such Loan or
     releases any substantial portion of collateral, if any, securing any such
     Loan.

             12.2.3. BENEFIT OF SETOFF. The Borrower agrees that each
     Participant shall be deemed to have the right of setoff provided in
     SECTION 11.1 in respect of its participating interest in amounts owing
     under the Loan Documents to the same extent as if the amount

                                     - 58 -
<Page>

     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 "H" hereto. Unless
     a Default has occurred and is continuing, the written 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 or an Affiliate
     thereof. Such consent shall be in form and substance satisfactory to the
     Agent and shall not be unreasonably withheld.

             12.3.2. EFFECT; EFFECTIVE DATE. Upon (i) delivery to the Agent of a
     notice of assignment, substantially in the form attached as EXHIBIT "I" to
     EXHIBIT "H" hereto (a "NOTICE OF ASSIGNMENT"), together with any consents
     required by SECTION 12.3.1, and (ii) payment of a $2,500 fee to the Agent
     for processing such assignment, such assignment shall become effective on
     the effective date specified in such Notice of Assignment. On and after the
     effective date of such assignment, such Purchaser shall for all purposes be
     a Lender party to this Agreement and any other Loan Document executed by
     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 make appropriate arrangements so that 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 in writing for the
benefit of the Borrower to be bound by SECTION 9.14.

                                     - 59 -
<Page>

     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 2.25.

                                  ARTICLE XIII

                                     NOTICES

     13.1.   GIVING NOTICE. Except as otherwise permitted by SECTION 2.20 with
respect to Borrowing Notices and Continuation/Conversion Notices, all notices
and other communications provided to any party hereto under this Agreement or
any other Loan Document shall be in writing or by facsimile and addressed or
delivered to such party at its address set forth below its signature hereto or
at such other address as may be designated by such party in a notice to the
other parties. Any notice, if mailed and properly addressed with postage
prepaid, shall be deemed given when received; any notice, if transmitted by
facsimile, shall be deemed given when transmitted.

     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, TERMINATION OF ORIGINAL CREDIT AGREEMENT

                                AND EFFECTIVENESS

     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. By their execution of
this Agreement, each of the Borrower and the Lenders hereby agree that as of the
Restatement Effective Date the Original Credit Agreement shall be terminated and
of no further force and effect, except for the terms and provisions of the
Original Credit Agreement which expressly survive the termination thereof and
except for the Borrower's obligation to repay all accrued and unpaid fees
thereunder in accordance with the terms thereof. 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 telex, facsimile or telephone, that it
has taken such action.

                                     - 60 -

     IN WITNESS WHEREOF, the Borrower, the Lenders and the Agent have executed
this Agreement as of the date first above written.

The Lenders who are parties to the
Credit Agreement described below:

Gentlemen/Ladies:

     We are counsel for AAR Corp., a Delaware corporation (the "Borrower"), and
have represented the Borrower in connection with its execution and delivery of a
Second Amended and Restated Credit Agreement among the Borrower, Bank of America
National Trust and Savings Association, individually and as Agent, and the
Lenders named therein, providing for Advances in an aggregate principal amount
not exceeding $50,000,000 at any one time outstanding and dated as of May 27,
1998 (the "Agreement"). All capitalized terms used in this opinion and not
otherwise defined shall have the meanings attributed to them in the Agreement.

     We have examined the Borrower's articles of incorporation, by-laws,
resolutions, the Loan Documents and such other matters of fact and law which we
deem necessary in order to render this opinion. Based upon the foregoing, it is
our opinion that:

     1.      The Borrower and each Subsidiary are corporations duly
incorporated, validly existing and in good standing under the laws of their
states of incorporation and have all requisite authority to conduct their
business in each jurisdiction in which their business is conducted.

     2.      The execution and delivery of the Loan Documents by the Borrower
and the performance by the Borrower of the Obligations have been duly authorized
by all necessary corporate action and proceedings on the part of the Borrower
and will not:

             (a)    require any consent of the Borrower's shareholders;

             (b)    violate any law, rule, regulation, order, writ, judgment,
     injunction, decree or award binding on the Borrower or any of its
     Subsidiaries or the Borrower's or any Subsidiary's articles of
     incorporation or by-laws or any indenture, instrument or agreement binding
     upon the Borrower or any of its Subsidiaries; or

             (c)    result in, or require, the creation or imposition of any
     Lien pursuant to the provisions of any indenture, instrument or agreement
     binding upon the Borrower or any of its Subsidiaries.

     3.      The Loan Documents have been duly executed and delivered by the
Borrower and constitute legal, valid and binding obligations of the Borrower
enforceable in accordance with their terms except to the extent the enforcement
thereof may be limited by bankruptcy,

                                     - 72 -
<Page>

insolvency or similar laws affecting the enforcement of creditors' rights
generally and subject also to the availability of equitable remedies if
equitable remedies are sought.

     4.      Except as set forth in the Borrower's Form 10-K filed with the
Securities and Exchange Commission for its fiscal year ended _______________,
199_, there is no litigation or proceeding against the Borrower or any of its
Subsidiaries which, if adversely determined, could have a Material Adverse
Effect.

     5.      No approval, authorization, consent, adjudication or order of any
governmental authority, which has not been obtained by the Borrower or any of
its Subsidiaries, is required to be obtained by the Borrower or any of its
Subsidiaries in connection with the execution and delivery of the Loan
Documents, the borrowings under the Agreement or in connection with the payment
by the Borrower of the Obligations.

     This opinion may be relied upon by the Lenders and their participants,
assignees and other transferees. No opinion is expressed herein as to the
relation between the Agent and the Lenders or the relation between the Lenders.

                                                Very truly yours,

relating to "Lenders" under and as defined in the Credit Agreement, including,
without limitation, provisions relating to the dissemination of information and

interest and fees with respect to the Purchased Percentage of the Assignor's

Effective Date. In consideration for the transfer to the Purchaser of the
Purchased Percentage of the Loans made by the Assignor which are outstanding on
the Effective Date, (i) with respect to all Floating Rate Loans made by the
Assignor outstanding on the Effective Date, the Purchaser shall pay the
Assignor, on the Effective Date, an amount equal to the Purchased Percentage of
all such Floating Rate Loans; and (ii) with respect to each Fixed Rate Loan made
by the Assignor outstanding on the Effective Date, (a) on the last day of the

Purchased Percentage of such Fixed Rate Loan. On and after the Effective Date,
the Purchaser will also remit to the Assignor any amounts of interest on Loans
and fees received from the Agent which relate to the Purchased Percentage of
Loans made by the Assignor accrued for periods prior to the Effective Date, in
the case of Floating Rate Loans, or the Payment Date, in the case of Fixed Rate
Loans, and not heretofore paid by the Purchaser to the Assignor. In the event
interest for the period from the Effective Date to but not including the Payment
Date is not paid by the Borrower with respect to any Fixed Rate Loan sold by the
Assignor to the Purchaser hereunder, the Purchaser shall pay to the Assignor
interest for such period on such Fixed Rate Loan at the applicable rate provided
by the Credit Agreement. In the event that either party hereto receives any
payment to which the other is entitled under this Assignment Agreement, then the
party receiving such amount shall promptly remit it to the other party hereto.

receives a payment of interest or fees under the Credit Agreement (other than a
payment of interest or fees which the Purchaser is obligated to deliver to the

fees payable to the Assignor pursuant to this Section) the Purchaser shall pay
to the Assignor a fee. The amount of such fee shall be the difference between
(i) the amount of such interest or fee, as applicable, received by the Purchaser
and (ii) the amount of the interest or fee, as applicable, which would have been
received by the Purchaser if each interest rate was _____of 1% less than the

assignment from the Purchaser shall agree to assume all of the Purchaser's

     or (ii) the sum of (A) the aggregate principal amount of all Floating Rate
     Advances PLUS (B) the aggregate principal amount of all Advances other than

             (a)   The Borrower shall repay to the Lenders on the Revolving
     Credit Termination Date the aggregate principal amount of all Advances and
     other unpaid Obligations outstanding on such date.

             (b)   The Borrower shall repay each Alternate Currency Advance in
     full on the last day of its respective Transaction Rate Interest Period.

             (c)   From and after the Second Amendment Effective Date until the
     Adjustment Date, if the Borrower (or any Subsidiary) makes any scheduled,
     mandatory, or optional prepayments or repayments under any Parallel
     Agreement which would result in the aggregate of such payments under any
     such Parallel Agreement being greater than (as a percentage of the
     outstanding commitments thereunder) the aggregate of such payments since
     the Second Amendment Effective Date hereunder, then the Borrower shall
     concurrently prepay the Advances hereunder in an amount necessary to result
     in the aggregate of such payments hereunder since the Second Amendment
     Effective Date being not less than the aggregate of such payments (as a
     percentage of the outstanding commitments) under any such Parallel
     Agreement, subject to compliance with Section 3.4.

             (d)   On the Adjustment Date, the Borrower shall repay and adjust
     the outstanding borrowings and advances under the Parallel Agreements,
     including the Advances under this Agreement, in such a manner so that the
     aggregate outstanding borrowings and advances under the Parallel Agreements
     (including this Agreement) shall not exceed $60,000,000 as of the
     Adjustment Date. The foregoing limitation shall only apply on the
     Adjustment Date and shall not apply to subsequent borrowings.

             (e)   From and after the Adjustment Date, the outstanding Advances
     shall not at any time exceed the Ratable Amount of the total outstanding
     borrowings and advances under the Parallel Agreements (including this
     Agreement). If, at any time or from time to time, the aggregate amount of
     the outstanding Advances exceeds the Ratable Amount of the total
     outstanding borrowings and advances under the Parallel Agreements
     (including this Agreement), then the Borrower shall make an immediate
     repayment of the Advances to cause the Advances not to exceed such Ratable
     Amount.

     SECTION 2.7.  AMENDMENT TO SECTION 2.5. Section 2.5 of the Existing Credit
Agreement (Optional Reductions in Aggregate Commitment) is amended as follows:

     (a)     The word "Optional" in the heading is deleted.

                                        5
<Page>

     (b)     The existing wording in Section 2.5 is re-lettered as subsection
             (a), and the following sentence is added at the end thereof:

             "Any optional reduction in the Aggregate Commitments shall be
             applied against future scheduled reductions in the Aggregate
             Commitment in inverse order of scheduled occurrence."

     (c)     The following new subsections are inserted after such subsection
             (a) reading as follows:

                    (b)   The Aggregate Commitment shall automatically be
             reduced by $5,000,000 on each of June 30, 2002, December 31, 2002,
             and June 30, 2003 (each a "REDUCTION DATE").

                    (c)   No later than the Adjustment Date, the Borrower shall
             have arranged or implemented amendments or other modifications to
             the Parallel Agreements to provide that (i) the aggregate
             outstanding commitments under the Bank One Agreement shall be
             $40,000,000, (ii) the aggregate outstanding commitments under the
             LaSalle Agreement shall be $25,000,000, and (iii) the aggregate
             outstanding commitments under the U.S. Bank Agreement shall be
             $10,000,000. From and after the Adjustment Date, the Aggregate
             Commitment shall not exceed at any time the Ratable Amount of the
             Parallel Agreement Commitments. To the extent that the Borrower
             does not take any necessary steps to reduce the Aggregate
             Commitment in accordance with the requirements of this section,
             then the Aggregate Commitment shall automatically and concurrently,
             without notice or demand, reduce hereunder to an amount equal to
             the Ratable Amount of the Parallel Agreement Commitments.

                    (d)   Notwithstanding any provision herein to the contrary,
             for the avoidance of doubt, the Aggregate Commitment shall not
             automatically be reduced due to the reduction in the commitment
             under the Bank One Agreement scheduled to take effect on and after
             December 31, 2003, such scheduled reduction occurring on and after
             December 31, 2003 being in an amount not to exceed $5,000,000 in

             2.5(b) hereof, the aggregate

                                        6
<Page>

             Dollar Amount of all outstanding Advances exceeds the Aggregate
             Commitment as so reduced, Borrower shall immediately prepay the
             Advances in an aggregate amount equal to such excess, subject to
             compliance with Section 3.4.

                    "(c)   In addition to any prepayment required under
             subsection (b), if, as of the last day of any calendar month, the
             Agent determines that the aggregate Dollar Amount of all
             outstanding Advances exceeds the Aggregate Commitment then in
             effect by reason of currency fluctuations or otherwise, the
             Borrower shall, within three Business Days of demand by the Agent,
             prepay (in U.S. Dollars) the Advances in an aggregate amount equal
             to such excess, subject to compliance with Section 3.4."

             the Parallel Agreements as a percentage of the Parallel Agreement
             Commitments, except with respect to any Parallel Agreement where
             the Borrower has exhausted the available aggregate commitment
             thereunder; and (B) from and after the Adjustment Date, the
             Borrower has made or is making ratable borrowings under each of the
             Parallel Agreements (including this Agreement) so that the amount

             Amount. In addition, the Borrower shall have delivered to the Agent
             with each such Borrowing Notice (for delivery to the Lenders)
             copies of the borrowing notices delivered under such Parallel

immediately following Section 6.24, which reads in its entirety as follows:

             6.25  COVENANT TO MAINTAIN COMPARABLE TERMS AMONG LENDERS. Unless

     interest rates, Applicable Margins, and Facility Fees hereunder are not
     less than the comparable effective interest rates, margins and fees under
     any Parallel Agreement; and (b) the affirmative and negative covenants
     hereunder are not materially less burdensome on the Borrower or materially

             6.26  SYNTHETIC LEASE BORROWINGS AND AGGREGATE COMMITMENT.

             (a)   The Borrower will not and will cause its Subsidiaries and
     Affiliates not to deliver any Notice of Delivery which would cause the
     aggregate of (w) the amounts requested to be funded in such Notice of
     Delivery, (x) the amounts requested to be funded in all other Notices of
     Delivery which have neither been funded nor revoked, (y) all outstanding
     Loans with respect to all Aircraft and Engines, and (z) all outstanding
     Certificate Amounts with respect to all Aircraft and Engines to exceed
     $40,000,000. The Borrower covenants to cause, at all times, the aggregate
     Loans and Certificate Amounts not to exceed $40,000,000.

             (b)   The Borrower covenants and agrees that, on or before February
     28, 2002, it will, and shall cause its Subsidiaries and/or Affiliates as
     appropriate to, use commercially reasonable best efforts, to cause the
     implementation and effectiveness of an amendment to the Synthetic Lease
     Documents which (i) effects a reduction in the Maximum Revolving Commitment
     Amount and a pro rata reduction in each Participant's Commitment to cause
     the aggregate of all Participants' Revolving Commitments to be

                                        8
<Page>

     equal to $40,000,000, and (ii) amends the net worth and fixed charged
     coverage ratios therein to conform to the same ratios in the Amended Credit
     Agreement. The failure of any other party to the Synthetic Lease Documents
     to agree to such amendments for whatever reasons on or before February 28,
     2002 or thereafter, or the failure of such amendments to occur because they
     would effectively cause, a default under the Synthetic Lease Documents, a
     termination of the synthetic lease program, or a Liquidity Purchase
     thereunder, shall not constitute a default under this covenant. In
     addition, the Borrower's covenant and agreement under this paragraph (b) is
     subject to the Agent complying with its agreement under Section 5.3 of the
     Second Amendment. Capitalized terms used in this Section 6.26 and not

     613, 614, 615, 6.16, 6.17, 6.19 or 6.26(b) which is not remedied within 10

       (g)  The definition of Facility Termination Date shall be amended and
       read as follows:

              "Facility Termination Date" means the Revolving Credit Termination
              Date.

       will be reduced such that the Borrower's total aggregate committed credit
       facilities from all lenders (including the Lenders) shall not exceed $125
       million.

       (i)  Section 2.6 shall be amended and read as follows:

              2.6. RATABLE LOANS. Each Advance hereunder shall consist of Loans
       from the several Lenders ratably in proportion to the ratio that their
       respective Commitments bear to the Aggregate Commitment. In the event the
       Borrower desires an advance that brings the aggregate principal Dollar
       Amount of all Advances then outstanding in excess of $5 million at any
       time after November 30, 2001, the Advance hereunder related to such
       desired amount shall be in proportion to the ratio that the Aggregate
       Commitment bears to the total aggregate commitments (including the
       Aggregate Commitment) from all lenders providing Borrower an unsecured
       committed credit facility equal to or greater than $20 million (but in
       all cases including the unsecured committed amount provided under the
       Bank of America Agreement, and the LaSalle Agreement), and Borrower shall
       obtain pro-rata borrowings from such other lenders to obtain the total
       desired advance.

       (j)  Insert a new definition to read as follows:

              "LaSalle Agreement" means the Revolving Loan Agreement dated as of
       April 11, 2001 between the Borrower and LaSalle Bank National
       Association, as the same may from time to time be amended, supplemented
       or otherwise modified, and including any replacement unsecured credit
       facility between the Borrower and LaSalle Bank National Association.

                                        3

       (k)  Insert a Section 9.16 to read as follows:

              9.16. MOST FAVORED PRICING/COVENANT PROVISION. The Borrower
       agrees that the Facility Fee, interest rates, and covenants hereunder
       shall be automatically modified to reflect any similar facility fee,
       interest rate or covenant set forth in the Bank of America Agreement, the
       LaSalle Agreement or any other unsecured credit facility entered into
       with another lender, but only to the extent that said fee or interest
       rate is higher or said covenant is more restrictive than as set forth in
       this Agreement.
