which is attributable to such Projects. If a Project has been acquired during

pro forma Property Operating Income and Capital Expenditure Reserve Amount from
such Project for the entire calculation period in the foregoing calculation. If
a Project is no longer owned as of the date of calculation, then no value shall
be included based on capitalizing Property Operating Income from such Project
and no Capital Expenditure Reserve Amount shall be deducted on account of such
Project.

and the plural forms of the defined terms.

                                   ARTICLE II

                                  THE FACILITY

     2.1 THE FACILITY.

          (a) Subject to the terms and conditions of this Agreement and in
reliance upon the representations and warranties of Borrower contained herein,
Lenders agree, severally and not jointly, to make Advances through the Agent to
Borrower from time to time prior to the Maturity Date, provided that the making
of any such Advance will not cause the then Allocated Facility Amount to exceed
the then-current Aggregate Commitment. The Advances may be ratable Alternate
Base Rate Advances, ratable LIBOR Advances or non-pro rata Swingline Loans.
Except as provided in SECTION 2.16 hereof, each Lender shall be required to fund
only its Percentage of each such Advance and no Lender will be required to fund
any amounts which when aggregated with such Lender's Percentage of (i) all other
Advances then outstanding, (ii) all Swingline Advances and (iii) all Facility
Letter of Credit Obligations would exceed such Lender's then-current Commitment.
This facility ("FACILITY") is a revolving credit facility and, subject to the
provisions of this Agreement, Borrower may request Advances hereunder, repay
such Advances and reborrow Advances at any time prior to the Maturity Date.

          (b) The Facility created by this Agreement, and that Commitment of
each Lender to lend hereunder, shall terminate on the Maturity Date, unless
sooner terminated in accordance with the terms of this Agreement.

          (c) In no event shall the Aggregate Commitment exceed Two Hundred
Million Dollars ($200,000,000).

     2.2 FINAL PRINCIPAL PAYMENT AND EXTENSION OPTION. Any outstanding Advances
and all other unpaid Obligations shall be paid in full by the Borrower on the
Maturity Date. The Maturity Date can be extended for a single extension period
of one (1) year upon request ("Extension Request") delivered by the Borrower to
the Agent not later than sixty (60) days, nor earlier than one hundred twenty
(120) days, prior to the Maturity Date, if, but only if (i) no Default has
occurred and is continuing at the time of such Extension Request or at the time
of the Maturity Date and Borrower shall have delivered to the Agent a
certificate to that effect both concurrently with the delivery of the Extension
Request and on the scheduled Maturity Date; (ii) the Required Lenders agree to
such extension; and (iii) Borrower pays the Extension Fee at the time of the
initially scheduled Maturity Date (which fee shall be paid to the Agent for
distribution to the Lenders which will have continuing Commitments). Promptly
upon receipt from the Borrower of any Extension Request, the Agent shall notify
each Lender of the contents of such notice. Each Lender approving an Extension
Request shall deliver its written consent (a "Consent Notice") to the Borrower
and the Agent on or prior to the fifteenth (15th) day after the date on which
such notice is sent by the Agent to the Lenders (the "Response Date"). Each
Lender may give or withhold its consent to any Extension Request in its sole
discretion. No extension shall be effective with respect to any Lender which (i)
by notice (a "Withdrawal Notice") to the Borrower and the Agent prior to the
Response Date declines to consent to such Extension Request or (ii) fails to
respond to the Borrower and the Agent prior to the Response Date (each such
Lender is referred to as a "Withdrawing Lender" and each Lender other than a
Withdrawing Lender is referred to as a "Continuing Lender"). The Agent shall
promptly notify

                                       18
the Borrower and the Lenders whether the Extension Request was approved or
denied. If the consent of the Required Lenders to any such Extension Request is
received by the Agent on or prior to the Response Date and the other
requirements set forth above for the effectiveness of the extension are
satisfied then, (i) the new Maturity Date shall become effective on the initial
scheduled Maturity Date, (ii) the Agent shall promptly notify the Borrower and
each Lender of the new Maturity Date, (iii) the Commitments of the Continuing
Lenders shall be extended to the new Maturity Date and (iv) the Withdrawing
Lenders shall be paid in full and their Commitments shall be cancelled or
assumed by new lenders selected by the Borrower and the Arranger on the initial
scheduled Maturity Date. Upon repayment of a Withdrawing Lender's Loans, such
Lender shall be released from this Agreement, its Percentage of the Aggregate
Commitment, and all of the rights and obligations under this Agreement as of the
date of such release. Such Lender will remain responsible for all obligations
accruing prior to the date of such release and shall be entitled to all benefits
(such as indemnities from the Borrower) accruing prior to the date of such
release. Concurrently with such release, the Aggregate Commitment shall be
reduced by the Commitment of the Lender that is released and the Percentages
shall be recalculated, unless the Borrower arranges for a new lender to assume
such Lender's Commitment by assignment in accordance with the terms of this
Agreement.

         2.3      Advances funded by the Lenders shall be made available to
Borrower by Agent in accordance with SECTION 2.1(A) and SECTION 2.11 hereof. The
obligation of each Lender to fund its Percentage of each ratable Advance shall
be several, and not joint or joint and several.

         2.4      EVIDENCE OF CREDIT EXTENSIONS. The Advances of each Lender
outstanding at any time shall be evidenced by the Notes. Each Note executed by
the Borrower shall be in a maximum principal amount equal to each Lender's
Percentage of the Aggregate Commitment. Each Lender shall record Advances and
principal payments thereof on the schedule attached to its Note or, at its
option, in its records, and each Lender's record thereof shall be conclusive
absent Borrower furnishing to such Lender conclusive and irrefutable evidence of
an error made by such Lender with respect to that Lender's records.
Notwithstanding the foregoing, the failure to make, or an error in making, a
notation with respect to any Advance or payment shall not limit or otherwise
affect the obligations of Borrower hereunder or under the Notes to pay the
amount actually owed by Borrower to Lenders.

         2.5      RATABLE LOANS. Each Advance hereunder shall consist of Loans
made from the several Lenders ratably in proportion to their Percentages, except
for Swingline Loans which shall be made by the Swingline Lender in accordance
with SECTION 2.16. The ratable Advances may be Alternate Base Rate Advances,
LIBOR Advances or a combination thereof selected by the Borrower in accordance
with SECTIONS 2.10 and 2.11.

         2.6      APPLICABLE MARGINS AND FACILITY FEE RATE. The Applicable
Margin over the then Alternate Base Rate or LIBOR Rate, as applicable to the
Advance(s) in question, and the Facility Fee Rate, shall vary from time to time
in accordance with Borrower's Leverage Ratio. The Applicable Margin and Facility
Fee Rate shall be adjusted when the Borrower's actual Leverage Ratio as of the
end of any fiscal quarter has been determined, effective as of the last day of
such fiscal quarter, if the change in Borrower's Leverage Ratio gives rise to
such an adjustment. The applicable Leverage Ratios, Applicable Margins and
Facility Fee Rates are set forth in the following table:

         All margins and fees are in basis points per annum. "Leverage Ratio" as
used in this Section 2.6 does not include any adjustment to liabilities or
assets based on Build to Suit Projects.

         2.7      FACILITY FEE. The Borrower agrees to pay to the Agent for the
account of each Lender a facility fee (the "FACILITY FEE") calculated on a daily
basis beginning on the Agreement Execution Date and each day thereafter while
the Aggregate Commitments are in effect equal to the applicable per annum
Facility Fee Rate in effect for such day, as shown in SECTION 2.6 hereof,
converted to a per diem rate, times the then Aggregate Commitment. The Facility
Fee shall be shared among the Lenders based on their respective Percentages and
shall be paid quarterly in arrears on the last Business Day of each calendar

however, that any Alternate Base Rate Advance may be in the amount of the unused
Aggregate Commitment.

         2.10     INTEREST.

                  (a)      The outstanding  principal balance under the Notes
shall bear interest from time to time at a rate per annum equal to:

                           (i)      the Adjusted Alternate Base Rate; or

                           (ii)     at the election of Borrower with respect to
                  all or portions of the Obligations, the Adjusted LIBOR Rate.

                  (b)      All interest shall be calculated for actual days
elapsed on the basis of a 360-day year. Interest accrued on each Advance shall
be payable in arrears on the first day of each calendar month, commencing with
the first such date to occur after the date hereof, and the Maturity Date.
Interest shall not be payable for the day of any payment on the amount paid if

                                       20
<PAGE>

payment is received by Agent prior to noon (Chicago time). If any payment of
principal or interest under the Notes shall become due on a day that is not a
Business Day, such payment shall be made on the next succeeding Business Day
and, in the case of a payment of principal, such extension of time shall be
included in computing interest due in connection with such payment.

         2.11     SELECTION OF RATE OPTIONS AND LIBOR INTEREST PERIODS.

                  (a) Borrower, from time to time, may select the Rate Option
and, in the case of each LIBOR Advance, the commencement date (which shall be a
Business Day) and the length of the LIBOR Interest Period applicable to each
LIBOR Advance. Borrower shall give Agent irrevocable notice (a "Borrowing
Notice") not later than 11:00 a.m. (Chicago time) (i) at least one Business Day
prior to a Alternate Base Rate Advance other than a Swingline Loan, (ii) at
least three (3) Business Days prior to a ratable LIBOR Advance, and (iii) not
later than 11:00 a.m. (Chicago time) on the Borrowing Date for each Swingline
Loan, specifying:

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

                           (ii)     the aggregate amount of such Advance,

                           (iii)    the type of Advance selected, and

                           (iv)     in the case of each LIBOR Advance, the
                  LIBOR Interest Period applicable thereto.

         The Borrower shall also deliver together with each Borrowing Notice the
compliance certificate referenced in SECTION 5.2(a), if required, and otherwise
comply with the conditions set forth in SECTION 5.2 for Advances. Agent shall
provide each Lender by facsimile with a copy of each Borrowing Notice (and any
compliance certificate) as soon as practicable after receipt, and if timely
received by Agent in accordance with this SECTION 2.11(a), Agent shall provide
same by 4:00 p.m. (Chicago time) on the same Business Day received. Unless
otherwise requested in writing by Borrower prior to such date, with respect to
each Reimbursement Obligation, the Borrower hereby irrevocably requests an
Adjusted Alternate Base Rate Advance on each Business Day on which Reimbursement
Obligations are due, in the amount of such Reimbursement Obligations, and the
Agent shall give the Lenders notice of each such requested Advance in the same
manner as other Adjusted Alternate Base Rate Advances.

         Not later than noon (Chicago time) on each Borrowing Date, each Lender
shall make available its Loan or Loans, in funds immediately available in
Chicago to the Agent. Agent will promptly make the funds so received from the
Lenders available to the Borrower.

                  (b)      Agent shall, as soon as practicable after receipt of
a Borrowing Notice requesting a LIBOR Advance, determine the Adjusted LIBOR Rate
applicable to the requested ratable LIBOR Advance and inform Borrower and
Lenders of the same. Each determination of the Adjusted LIBOR Rate by Agent
shall be conclusive and binding upon Borrower in the absence of manifest error.

                                       21
<PAGE>

                  (c)      If Borrower shall prepay a LIBOR Advance other than
on the last day of the LIBOR Interest Period applicable thereto, Borrower shall
be responsible to pay all amounts due to Lenders as required by SECTION 4.4
hereof.

                  (d)      As of the end of each LIBOR Interest Period selected
for a LIBOR Advance, the interest rate on the LIBOR Advance will become the
Adjusted Alternate Base Rate, unless Borrower has once again selected a LIBOR
Interest Period in accordance with the timing and procedures set forth in
SECTION 2.11(g).

                  (e)      The right of Borrower to select the Adjusted LIBOR
Rate for an Advance pursuant to this Agreement is subject to suspension as
described in SECTION 4.3. In addition, if (i) reasonable means do not exist for
determining an Adjusted LIBOR Rate, or (ii) the Adjusted LIBOR Rate would be in
excess of the maximum interest rate which Borrower may by law pay, then in
either of such events, Agent shall so notify Borrower and Lenders and such
Advance shall bear interest at the Adjusted Alternate Base Rate.

                  (f)      In no event may Borrower elect a LIBOR Interest
Period which would extend beyond the scheduled Maturity Date. In no event may
Borrower have more than five (5) different LIBOR Interest Periods for LIBOR
Advances outstanding at any one time or have more than five (5) LIBOR Interest
Periods expiring in any thirty (30) day period.

                  (g)      Conversion and Continuation.

                           (i)      Borrower may elect from time to time,
                  subject to the other provisions of this SECTION 2.11, to
                  convert all or any part of a ratable Advance into any other
                  type of Advance; provided that any conversion of a ratable
                  LIBOR Advance shall be made on, and only on, the last day of
                  the LIBOR Interest Period applicable thereto.

                           (ii)     Alternate Base Rate Advances shall continue
                  as Alternate Base Rate Advances unless and until such
                  Alternate Base Rate Advances are converted into ratable LIBOR
                  Advances pursuant to a Conversion/Continuation Notice from
                  Borrower in accordance with SECTION 2.11(g)(iv). Ratable LIBOR
                  Advances shall continue until the end of the then applicable
                  LIBOR Interest Period therefor, at which time each such
                  Advance shall be automatically converted into an Alternate
                  Base Rate Advance unless the Borrower shall have given the
                  Agent a Conversion/Continuation Notice in accordance with
                  SECTION 2.11(g)(iv) requesting that, at the end of such LIBOR
                  Interest Period, such Advance either continue as an Advance of
                  such type for an additional LIBOR Interest Period of the same
                  or different duration.

                           (iii)    Notwithstanding anything to the contrary
                  contained in this SECTION 2.11(g), no Advance may be converted
                  into a LIBOR Advance or continued (following the end of a
                  LIBOR Interest Period) as a LIBOR Advance when any Monetary
                  Default or Event of Default has occurred and is continuing.

                           (iv)     The Borrower shall give the Agent
                  irrevocable notice (a "Conversion/Continuation Notice") of
                  each conversion of an Advance or continuation of a LIBOR
                  Advance not later than 11:00 a.m. (Chicago time) on the

                                       22
<PAGE>

                  Business Day immediately preceding the date of the requested
                  conversion, in the case of a conversion into an Alternate Base
                  Rate Advance, or 11:00 a.m. (Chicago time) at least three (3)
                  Business Days prior to the date of the requested conversion or
                  continuation, in the case of a conversion into or continuation
                  of a ratable LIBOR Advance, specifying: (1) the requested date
                  (which shall be a Business Day) of such conversion or
                  continuation; (2) the amount and type of the Advance to be
                  converted or continued; and (3) the amounts and type(s) of
                  Advance(s) into which such Advance is to be converted or
                  continued and, in the case of a conversion into or
                  continuation of a ratable LIBOR Advance, the duration of the
                  LIBOR Interest Period applicable thereto.

                           (v)      Agent shall provide each Lender by facsimile
                  with a copy of each Conversion/Continuation Notice as soon as
                  practicable after receipt, and if timely received by Agent in
                  accordance with SECTION 2.11(g)(iv) above, Agent shall provide
                  same by 4:00 p.m. (Chicago time) on the same Business Day it
                  is received.

         2.12     METHOD OF PAYMENT. All payments of the Obligations hereunder
shall be made, without set-off, deduction, or counterclaim, in immediately
available funds by wire transfer to Agent's account designated in writing from
time to time by notice to Borrower or, in the absence of such notice, to Agent
at its address specified herein, or at any other Lending Installation specified
in writing by Agent to Borrower, by noon (local time) on the date when due and
shall be applied ratably by Agent among the Lenders, except as otherwise
provided herein. Each payment received by Agent for the account of any Lender by
the time of day specified herein shall be delivered on the same Business Day by
Agent to such Lender in the same type of funds that Agent received at its
address specified above in this SECTION 2.12 or at any Lending Installation
specified in a notice received by Agent from such Lender. All payments received
by the Agent from the Borrower for the account of the Lenders after the time of
day specified herein shall be disbursed to the applicable Lenders no later than
the next Business Day, following the day such payment is received in good funds
by the Agent. If payments received by the Agent from the Borrower are not
disbursed to the applicable Lenders on the date required by this Section, any
Lender not receiving such disbursement will receive interest from the Agent at
the Federal Funds Effective Rate for each day of delay in such disbursement.
Agent is hereby authorized to charge the account, if any, of Borrower maintained
with Bank One for each payment of principal, interest and fees as it becomes due
hereunder.

         2.13     DEFAULT. Notwithstanding the foregoing, during the continuance
of a Monetary Default, any other material Default, or any Event of Default,
Borrower shall not have the right to request a LIBOR Advance, continue or select
a new LIBOR Interest Period for an existing ratable LIBOR Advance or convert any
Alternate Base Rate Advance to a ratable LIBOR Advance. During the continuance
of a Monetary Default or any Event of Default, outstanding Advances shall bear
interest at the applicable Default Rates until such Monetary Default or Event of
Default ceases to exist or the Obligations are paid in full.

         2.14     LENDING INSTALLATIONS. Each Lender may book its Loans at any
Lending Installation selected by such Lender and may change its Lending
Installation from time to time. All terms of this Agreement shall apply to any
such Lending Installation and the Notes shall be deemed held by each Lender for
the benefit of such Lending Installation. Each Lender may, by

                                       23
<PAGE>

written notice to the Agent and Borrower, designate a Lending Installation
through which Loans will be made by it and for whose account payments are to be
made.

         2.15     NON-RECEIPT OF FUNDS BY AGENT. Unless Borrower or a Lender, as
the case may be, has notified Agent prior to the date on which it is scheduled
to make payment to Agent of (i) in the case of a Lender, an Advance, or (ii) in
the case of Borrower, a payment of principal, interest or fees to the Agent for
the account of the Agent or any or all of the Lenders, that it does not intend
to make such payment (which notice shall not affect the obligations of Borrower
or any Lender, as the case may be, hereunder), and such notice has been received
by Agent, Agent may assume that such payment will be made when due. 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 Borrower,
as the case may be, has not in fact made such payment to Agent, the recipient of
such payment shall, on demand by Agent, repay to 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 Agent until
the date 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 (as determined by
Agent) for such day or (ii) in the case of payment by Borrower, the interest
rate applicable to the relevant Advance. Nothing in this SECTION 2.15 shall be
deemed to relieve any Lender from its obligations to fulfill its Commitment or
to relieve Borrower of any of its obligations under this Agreement, or to
prejudice any rights which the Borrower may have against any Lender, or any
Lender may have against Borrower, upon a default of such obligations. No Lender
shall be responsible for any default by another Lender and each Lender shall be
obligated to make the Loans provided to be made by it under, and subject to the
terms of this Agreement, regardless of the failure of any other Lender to
fulfill its Commitment hereunder.

         2.16     SWINGLINE LOANS. In addition to the other options available to
Borrower hereunder, the amount of the Swingline Commitment, shall be available
for Swingline Loans subject to the following terms and conditions. Swingline
Loans shall be made available for same day borrowings provided that notice is
given in accordance with SECTION 2.11(a) hereof. All Swingline Loans shall bear
interest at the Adjusted Alternate Base Rate and shall be deemed to be Alternate
Base Rate Advances. In no event shall the Swingline Lender be required to fund a
Swingline Loan if it would increase the total aggregate outstanding Loans
(including both Swingline Loans and ratable Loans) by Swingline Lender hereunder
plus its Percentage of Facility Letter of Credit Obligations to an amount in
excess of its Commitment. Upon request of the Swingline Lender made to all the
Lenders (which request shall be made not later than five (5) Business Days after
such Swingline Loan is funded by Swingline Lender), each Lender irrevocably
agrees to purchase its Percentage of any Swingline Loan made by the Swingline
Lender regardless of whether the conditions for disbursement are satisfied at
the time of such purchase, including the existence of an Event of Default
hereunder, provided no Lender shall be required to have total outstanding Loans
plus its Percentage of Facility Letter of Credit Obligations in an amount
greater than its Commitment. Such purchase shall take place on the date of the
request by Swingline Lender so long as such request is made by noon (Chicago
time), otherwise on the next Business Day following such request. All requests
for purchase shall be in writing. From and after the date it is so purchased,
each such Swingline Loan shall, to the extent purchased, (i) be treated as a
Loan made by the purchasing Lenders and not by the selling Lender for all
purposes under this Agreement and the payment of the purchase price by a Lender
shall be deemed to be the making of a Loan by such Lender and shall constitute
outstanding principal

                                       24
<PAGE>

under such Lender's Note, and (ii) shall no longer be considered a Swingline
Loan, except that all interest accruing on or attributable to such Swingline
Loan for the period prior to the date of such purchase shall be paid when due by
the Borrower to the Agent for the benefit of the Swingline Lender, but shall be
considered an Alternate Base Rate Advance by each such Lender and all interest
accruing on or attributable to such Loans for the period from and after the date
of such purchase shall be paid when due by the Borrower to the Agent for the
benefit of the purchasing Lenders. If prior to purchasing its Percentage of a
Swingline Loan one of the events described in SECTION 10.10 shall have occurred
and such event prevents the consummation of the purchase contemplated by the
preceding provisions, each Lender will purchase an undivided participating
interest in the outstanding Swingline Loan in an amount equal to its Percentage
of such Swingline Loan. From and after the date of each Lender's purchase of its
participating interest in a Swingline Loan, if the Swingline Lender receives any
payment on account thereof, the Swingline Lender will distribute to such Lender
its participating interest in such amount (appropriately adjusted, in the case
of interest payments, to reflect the period of time during which such Lender's
participating interest was outstanding and funded); provided, however, that in
the event that such payment was received by the Swingline Lender and is required
to be returned to the Borrower, each Lender will return to the Swingline Lender
any portion thereof previously distributed by the Swingline Lender to it. If any
Lender fails to so purchase its Percentage of any Swingline Loan, such Lender
shall be deemed to be a Defaulting Lender hereunder. No Swingline Loan shall be
outstanding for more than five (5) consecutive days at a time, and Swingline
Loans shall not in the aggregate be outstanding for more than ten days in any
calendar month.

         2.17     APPLICATION OF MONEYS  RECEIVED.  All moneys  collected or
received by the Agent on account of the Facility directly or indirectly, shall
be applied in the following order of priority:

                           (i)      to the  payment of all  expenses  then due
                  and payable by Borrower  hereunder,  including,  without
                  limitation, costs incurred in the collection of such moneys;

                           (ii)     to the  reimbursement of any yield
                  protection due to any of the Lenders in accordance with
                  SECTION 4.1;

                           (iii)    to the payment of all indemnity obligations
                  then due and payable by Borrower hereunder;

                           (iv)     first to the payment of any fee due pursuant
                  to SECTION 3.8(b) in connection with the issuance of a
                  Facility Letter of Credit to the Issuing Bank until such fee
                  is paid in full, then next to the payment of the Facility Fee
                  and Facility Letter of Credit Fee to the Lenders, if then due,
                  in that order on a pro rata basis in accordance with the
                  respective amounts of such fees due to the Lenders and then
                  finally to the payment of all fees then due to the Agent in
                  its capacity as Agent and not as a Lender;

                           (v)      to payment of the full amount of interest
                  and principal on the Swingline Loans;

                                       25
<PAGE>

                           (vi)     first to interest until paid in full and
                  then to principal for all Lenders (other than Defaulting
                  Lenders) (i) in accordance with the Percentages of the Lenders
                  or (ii) if an Event of Default exists, in accordance with the
                  respective Funded Percentages of the Lenders;

                           (vii)    any other sums due to the Agent or any
                  Lender under any of the Loan Documents; and

                           (viii)   to the payment of any sums due to each
                  Defaulting Lender as their respective Percentages appear
                  (provided that Agent shall have the right to set-off against
                  such sums any amounts due from such Defaulting Lender).

         2.18     VOLUNTARY REDUCTION OF AGGREGATE COMMITMENT AMOUNT. Upon at
least fifteen (15) days prior irrevocable written notice (or telephone notice
promptly confirmed in writing) to the Agent, Borrower shall have the right,
without premium or penalty, to terminate the Aggregate Commitment in whole or in
part provided that (a) Borrower may not reduce the Aggregate Commitment below
the Allocated Facility Amount at the time of such requested reduction, and (b)
any such partial termination shall be in the minimum aggregate amount of Five
Million Dollars ($5,000,000.00) or any integral multiple of Five Million Dollars
($5,000,000.00) in excess thereof. Any partial termination of the Aggregate
Commitment shall be applied pro rata to each Lender's Commitment.

         2.19     FUTURE INCREASE IN AGGREGATE COMMITMENT. The Borrower shall
have the right to increase the Aggregate Commitment up to a maximum of
$200,000,000 by either adding new banks as Lenders (subject to the Agent's prior
written approval of the identity of such new banks) or obtaining the agreement,
which shall be at each such Lender's sole discretion, of one or more of the
then-current Lenders to increase its or their Commitments. Each such increase
may only be exercised prior to the Borrower's delivery of an Extension Request
under Section 2.2 above. No more than two increases may be effected and each
increase must be not less than $25,000,000. Such increase shall be evidenced by
the execution and delivery of an Amendment in the form of EXHIBIT C attached
hereto by the Borrower, the Agent and the new bank or existing Lender providing
such additional Commitment, a copy of which shall be forwarded to each Lender by
the Agent promptly after execution thereof. On the effective date of each such
increase in the Aggregate Commitment, the Borrower and the Agent shall cause the
new or existing Lenders providing such increase, by either funding more than its
or their Percentage of new ratable Advances made on such date or purchasing
shares of outstanding ratable Loans held by other Lenders or a combination
thereof, to hold its or their Percentage of all ratable Advances outstanding at
the close of business on such day. The Lenders agree to cooperate in any
required sale or purchase of outstanding ratable Advances to achieve such
result, provided that if any such required sale results in a prepayment of any
outstanding ratable LIBOR Advances, Borrower shall make all payments required by
SECTION 4.4 to Lenders.

         2.20     TERMINATION OF EXISTING FACILITY. Borrower hereby agrees that
the initial Advance hereunder shall include an amount sufficient to repay in
full all of the outstanding amounts owing under that certain existing credit
facility (the "Existing Facility") from Bank of America National Trust and
Savings Association, as agent for the lenders thereunder, to Borrower (as same
may be amended or supplemented from time to time) and that all such outstanding
amounts shall be repaid simultaneously with such initial Advance.

         3.1      OBLIGATION TO ISSUE. Subject to the terms and conditions of
this Agreement and in reliance upon the representations and warranties of the
Borrower herein set forth, the Issuing Bank hereby agrees to issue for the

obligation to (and without the prior approval of all of the Lenders, shall not):

                           (i)      issue any Facility Letter of Credit if the
                  aggregate maximum amount then available for drawing under
                  Letters of Credit issued by such Issuing Bank, after giving
                  effect to the Facility Letter of Credit requested hereunder,
                  shall exceed any limit imposed by law or regulation upon such
                  Issuing Bank;

                           (ii)     issue any Facility Letter of Credit if,
                  after giving effect thereto, either (1) the then applicable
                  Allocated Facility Amount would exceed the then current
                  Aggregate Commitment, or (2) the Facility Letter of Credit
                  Obligations would exceed $10,000,000;

                           (iii)    issue any Facility Letter of Credit having
                  an expiration date, or containing automatic extension
                  provisions to extend such date, to a date which is after the
                  Business Day immediately preceding the scheduled Maturity

         3.3      CONDITIONS. In addition to being subject to the satisfaction
of the conditions contained in ARTICLE V hereof, the obligation of the Issuing
Bank to issue any Facility Letter of Credit is subject to the satisfaction in
full of the following conditions:

                           (i)      the Borrower shall have delivered to the
                  Issuing Bank at such times and in such manner as the Issuing
                  Bank may reasonably prescribe such documents and materials as
                  may be reasonably required pursuant to the terms of the
                  proposed Facility Letter of Credit (it being understood that
                  if any inconsistency exists between such documents and the
                  Loan Documents, the terms of the Loan Documents shall control)
                  and the proposed Facility Letter of Credit shall be reasonably
                  satisfactory to the Issuing Bank as to form and content;

                           (ii)     as of the date of issuance, no order,
                  judgment or decree of any court, arbitrator or governmental
                  authority shall purport by its terms to enjoin or restrain the
                  Issuing Bank from issuing the requested Facility Letter of
                  Credit and no law, rule or regulation applicable to the
                  Issuing Bank and no request or directive (whether or not
                  having the force of law) from any governmental authority with
                  jurisdiction over the Issuing Bank shall prohibit or request
                  that the

                                       27
<PAGE>

                  Issuing Bank refrain from the issuance of Letters of Credit
                  generally or the issuance of the requested Facility Letter or
                  Credit in particular; and

                           (iii)    there shall not exist any Default or Event
                  of Default.

         3.4      PROCEDURE FOR ISSUANCE OF FACILITY LETTERS OF CREDIT.

                  (a)      Borrower shall give the Issuing Bank and the Agent at
least five (5) Business Days' prior written notice of any requested issuance of
a Facility Letter of Credit under this Agreement (a "LETTER OF CREDIT REQUEST"),
a copy of which shall be sent immediately to all Lenders (except that, in lieu
of such written notice, the Borrower may give the Issuing Bank and the Agent
telephonic notice of such request if confirmed in writing by delivery to the
Issuing Bank and the Agent (i) by close of business on such day of a telecopy of
the written notice required hereunder which has been signed by an authorized
officer and contains all information required to be contained in such written
notice and (ii) promptly (but in no event later than the requested date of
issuance) of the written notice required hereunder containing the original
signature of an authorized officer); such notice shall specify:

         (1)      the stated amount of the Facility Letter of Credit requested
                  (which stated amount shall not be less than $50,000);

         (2)      the effective date (which day shall be a Business Day) of
                  issuance of such requested Facility Letter of Credit (the
                  "ISSUANCE DATE");

         (3)      the date on which such requested Facility Letter of Credit is
                  to expire;

         (4)      the purpose for which such Facility Letter of Credit is to be
                  issued;

         (5)      the Person who is to be the beneficiary under such Facility
                  Letter of Credit to be issued; and

         (6)      subject to SECTION 3.2, any special language required to be
                  included in the Facility Letter of Credit.

At the time such request is made, the Borrower shall also provide the Agent and
the Issuing Bank with a copy of the form of the Facility Letter of Credit that
the Borrower is requesting be issued. Such notice, to be effective, must be
received by such Issuing Bank and the Agent not later than 2:00 p.m. (Chicago
time) on the last Business Day on which notice can be given under this SECTION
3.4(a).

                  (b)      Subject to the terms and conditions of this
ARTICLE III and provided that the applicable conditions set forth in ARTICLE V
hereof have been satisfied, the Issuing Bank shall, on the Issuance Date, issue
a Facility Letter of Credit on behalf of the Borrower in accordance with the
Letter of Credit Request and the Issuing Bank's usual and customary business
practices unless the Issuing Bank has actually received (i) written notice from
the Borrower specifically revoking the Letter of Credit Request with respect to
such Facility Letter of Credit, or (ii) written or telephonic notice from the
Agent stating that the issuance of such Facility Letter of Credit would violate
SECTION 3.2 or SECTION 3.3.

                                       28
<PAGE>

                  (c)      The Issuing Bank shall give the Agent (who shall
promptly notify Lenders) and the Borrower written notice, or telephonic notice
confirmed promptly thereafter in writing, of the issuance of a Facility Letter
of Credit (the "ISSUANCE NOTICE"), including the information described in
SECTION 3.4(a).

                  (d)      The Issuing Bank shall not extend or amend any
Facility Letter of Credit (other than pursuant to an automatic extension) unless
the requirements of this SECTION 3.4 are met as though a new Facility Letter of
Credit was being requested and issued.

         3.5      REIMBURSEMENT OBLIGATIONS; DUTIES OF ISSUING BANK.

                  (a)      The Issuing Bank shall promptly notify the Borrower
and the Agent (who shall promptly notify Lenders) of any draw under a Facility
Letter of Credit. Any such draw shall constitute an Alternate Base Rate Advance
of the Facility in the amount of the Reimbursement Obligation with respect to
such Facility Letter of Credit and shall bear interest at the Adjusted Alternate
Base Rate from the date of the relevant drawing(s) under the pertinent Facility
Letter of Credit unless otherwise selected by Borrower in accordance with
SECTION 2.11 hereof; provided that if a Monetary Default or an Event of Default
exists at the time of any such drawing(s), then the Borrower shall reimburse the
Issuing Bank for drawings under a Facility Letter of Credit issued by the
Issuing Bank no later than the next succeeding Business Day after Borrower
receives notice of the payment by the Issuing Bank and until repaid such
Reimbursement Obligation shall bear interest at the Default Rate applicable to
Alternate Base Rate Advances.

                  (b)      Any action taken or omitted to be taken by the
Issuing Bank under or in connection with any Facility Letter of Credit, if taken
or omitted in the absence of willful misconduct or gross negligence, shall not
put the Issuing Bank under any resulting liability to any Lender or, provided
that such Issuing Bank has complied with the procedures specified in SECTION 3.4
relieve a Lender of its obligations hereunder to the Issuing Bank. In
determining whether to pay under any Facility Letter of Credit, the Issuing Bank
shall have no obligation relative to the Lenders other than to confirm that any
documents required to be delivered under such Letter of Credit appear to have
been delivered in compliance, and that they appear to comply on their face, with
the requirements of such Letter of Credit.

         3.6      PARTICIPATION.

                  (a)      Immediately upon issuance by the Issuing Bank of any
Facility Letter of Credit in accordance with the procedures set forth in SECTION
3.4, each Lender shall be deemed to have irrevocably and unconditionally
purchased and received from the Issuing Bank, without recourse, representation
or warranty, except as otherwise provided herein, an undivided interest and
participation equal to such Lender's Percentage in such Facility Letter of
Credit (including, without limitation, all obligations of the Borrower with
respect thereto) and all related rights hereunder and under the Guaranty and
other Loan Documents. Each Lender's obligation to make further Loans to Borrower
(other than any payments such Lender is required to make under subparagraph (b)
below) or to purchase an interest from the Issuing Bank in any subsequent
letters of credit issued by the Issuing Bank on behalf of Borrower shall be
reduced by such Lender's Percentage of the undrawn portion of each Facility
Letter of Credit outstanding.

                                       29
<PAGE>

                  (b)      In the event that the Issuing Bank makes any payment
under any Facility Letter of Credit and the Borrower shall not have repaid such
amount to the Issuing Bank pursuant to SECTION 3.7 hereof, the Issuing Bank
shall promptly notify the Agent, which shall promptly notify each Lender of the
same, and each Lender shall promptly and unconditionally pay to the Agent for
the account of the Issuing Bank the amount of such Lender's Percentage of the
unreimbursed amount of such payment, and the Agent shall promptly pay such
amount to the Issuing Bank. Notwithstanding the foregoing, unless Borrower shall
notify Agent of Borrower's intent to repay the Reimbursement Obligation on the
date of the related drawing under any Facility Letter of Credit, such
Reimbursement Obligation shall simultaneously with such drawing be converted to
and become an Alternate Base Rate Advance under SECTION 2.11. Each Lender's
payments of its Percentage of such Reimbursement Obligation as aforesaid shall
be deemed to be a Loan by such Lender as a part of the Alternate Base Rate
Advance into which such Reimbursement Obligation is converted and shall
constitute outstanding principal under such Lender's Note. The failure of any
Lender to make available to the Agent for the account of the Issuing Bank its
Percentage of the unreimbursed amount of any such payment shall not relieve any
other Lender of its obligation hereunder to make available to the Agent for the
account of such Issuing Bank its Percentage of the unreimbursed amount of any
payment on the date such payment is to be made, but no Lender shall be
responsible for the failure of any other Lender to make available to the Agent
its Percentage of the unreimbursed amount of any payment on the date such
payment is to be made. Any Lender which fails to make any payment required
pursuant to this SECTION 3.6(b) shall be deemed to be a Defaulting Lender
hereunder.

                  (c)      Whenever the Issuing Bank receives a payment on
account of a Reimbursement Obligation, including any interest thereon, the
Issuing Bank shall promptly pay to the Agent and the Agent shall promptly pay to
each Lender which has funded its participating interest therein, in immediately
available funds, an amount equal to such Lender's Percentage thereof. The timing
of the Agent's payments to the Lenders, and provision for interest on payments
not made timely, shall be the same as apply under Section 2.12 with respect to
other payments made by the Borrower.

                  (d)      Upon the request of the Agent or any Lender, the
Issuing Bank shall furnish to such Agent or Lender copies of any Facility Letter
of Credit to which the Issuing Bank is party and such other documentation as may
reasonably be requested by the Agent or Lender.

                  (e)      The obligations of a Lender to make payments to the
Agent for the account of the Issuing Bank with respect to a Facility Letter of
Credit shall be absolute, unconditional and irrevocable, not subject to any
counterclaim, set-off, qualification or exception whatsoever other than a
failure of any such Issuing Bank to comply with the terms of this Agreement
relating to the issuance of such Facility Letter of Credit, and such payments
shall be made in accordance with the terms and conditions of this Agreement
under all circumstances.

         3.7      PAYMENT OF REIMBURSEMENT OBLIGATIONS.

                  (a)      The Borrower agrees to pay to the Agent for the
account of the Issuing Bank the amount of all Advances for Reimbursement
Obligations, interest and other amounts payable to the Issuing Bank under or in
connection with any Facility Letter of Credit when due, irrespective of any
claim, set-off, defense or other right which the Borrower may have at any

                                       30
<PAGE>

time against any Issuing Bank or any other Person, under all circumstances,
including without limitation any of the following circumstances:

                           (i)      any lack of validity or enforceability of
                  this Agreement or any of the other Loan Documents;

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

                           (iii)    any draft, certificate or any other document
                  presented under the Facility Letter of Credit proving to be
                  forged, fraudulent, invalid or insufficient in any respect of
                  any statement therein being untrue or inaccurate in any
                  respect;

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

                           (v)      the occurrence of any Default or Event of
                  Default.

                  (b)      In the event any payment by the Borrower received by
the Issuing Bank or the Agent with respect to a Facility Letter of Credit and
distributed by the Agent to the Lenders on account of their participations is
thereafter set aside, avoided or recovered from the Agent or Issuing Bank in
connection with any receivership, liquidation, reorganization or bankruptcy
proceeding, each Lender which received such distribution shall, upon demand by
the Agent, contribute such Lender's Percentage of the amount set aside, avoided
or recovered together with interest at the rate required to be paid by the
Issuing Bank or the Agent upon the amount required to be repaid by the Issuing
Bank or the Agent.

         3.8      COMPENSATION FOR FACILITY LETTERS OF CREDIT.

                  (a)      The Borrower shall pay to the Agent, for the ratable
account of the Lenders, based upon the Lenders' respective Percentages, a per
annum fee (the "FACILITY LETTER OF CREDIT FEE") with respect to each Facility
Letter of Credit that is equal to the Applicable Margin applicable to LIBOR
Advances in effect from time to time. The Facility Letter of Credit Fee relating
to any Facility Letter of Credit shall be due and payable in arrears in equal
installments on the first Business Day of each month following the issuance of
any Facility Letter of Credit and, to the extent any such fees are then due and
unpaid, on the Maturity Date. The Agent shall promptly remit such Facility
Letter of Credit Fees, when paid, to the other Lenders in accordance with their
Percentages thereof. The Borrower shall not have any liability to any Lender for
the failure of the Agent to promptly deliver funds to any such Lender and shall
be deemed to have made all such payments on the date the respective payment is
made by the Borrower to the Agent, provided such payment is received by the time
specified in SECTION 2.12 hereof.

                                       31
<PAGE>

                  (b)      The Issuing Bank also shall have the right to receive
solely for its own account an issuance fee of 0.15% of the face amount of each
Facility Letter of Credit, payable by the Borrower on the Issuance Date for each
such Facility Letter of Credit. The Issuing Bank shall also be entitled to
receive its reasonable out-of-pocket costs and the Issuing Bank's standard
charges of issuing, amending and servicing Facility Letters of Credit and
processing draws thereunder.

         3.9      LETTER OF CREDIT COLLATERAL ACCOUNT. The Borrower hereby
agrees that it will, until all of the Obligations are paid and performed in
full, maintain a special collateral account (the "LETTER OF CREDIT COLLATERAL
ACCOUNT") at the Agent's office at the address specified pursuant to ARTICLE XV,
in the name of the Borrower but under the sole dominion and control of the
Agent, for the benefit of the Lenders, and in which the Borrower shall have no
interest other than as set forth in SECTION 11.1. In addition to the foregoing,
the Borrower hereby grants to the Agent, for the benefit of the Lenders, a
security interest in and to the Letter of Credit Collateral Account and any
funds that may hereafter be on deposit in such account, including income earned
thereon. The Lenders acknowledge and agree that the Borrower has no obligation
to fund the Letter of Credit Collateral Account unless and until so required
under SECTION 11.1 hereof and, if the Borrower does deposit any funds therein
prior to being so required, the Borrower may withdraw such funds so long as no
Monetary Default or Event of Default then exists.

                                   ARTICLE IV

                             CHANGE IN CIRCUMSTANCES

         4.1      YIELD PROTECTION. If, on or after the date of this Agreement,
the adoption of any law or any governmental or quasi-governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law), or any change in the interpretation or administration thereof by any
governmental or quasi-governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or compliance by any
Lender or applicable Lending Installation or the Issuing Bank with any request
or directive (whether or not having the force of law) of any such authority,
central bank or comparable agency:

                           (i)      subjects any Lender or any applicable
                  Lending Installation or the Issuing Bank to any Taxes, or
                  changes the basis of taxation of payments (other than with
                  respect to Excluded Taxes) to any Lender or the Issuing Bank
                  in respect of its LIBOR Loans, Facility Letters of Credit or
                  participations therein, 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 or the Issuing Bank (other
                  than reserves and assessments taken into account in
                  determining the interest rate applicable to LIBOR Advances),
                  or

                           (iii)    imposes any other condition the result of
                  which is to increase the cost to any Lender or any
                  applicable Lending Installation or the Issuing Bank of making,
                  funding or maintaining its LIBOR Loans, or of issuing or
                  participating in

                                       32
<PAGE>

                  Facility Letters of Credit, or reduces any
                  amount receivable by any Lender or any applicable Lending
                  Installation or the Issuing Bank in connection with its
                  LIBOR Loans, Facility Letters of Credit or participations
                  therein, or requires any Lender or any applicable Lending
                  Installation or the Issuing Bank to make any payment
                  calculated by reference to the amount of LIBOR Loans,
                  Facility Letters of Credit or participations therein held or
                  interest or fees received by it, by an amount deemed material
                  by such Lender or the Issuing Bank as the case may be,

and the result of any of the foregoing is to increase the cost to such Lender or
applicable Lending Installation or the Issuing Bank, as the case may be, of
making or maintaining its LIBOR Loans or Commitment or of issuing or
participating in Facility Letters of Credit or to reduce the return received by
such Lender or applicable Lending Installation or the Issuing Bank, as the case
may be, in connection with such LIBOR Loans, Commitment, Facility Letters of
Credit or participations therein, then, within 15 days after written demand by
such Lender or the Issuing Bank, as the case may be, describing the basis for
such demand the Borrower shall pay such Lender or the Issuing Bank, as the case
may be, such additional amount or amounts as will compensate such Lender or the
Issuing Bank, as the case may be, for such increased cost or reduction in amount
received.

         4.2      CHANGES IN CAPITAL ADEQUACY REGULATIONS. If a Lender
determines that the amount of capital required or expected to be maintained by
such Lender, any Lending Installation of such Lender or any corporate entity
controlling such Lender is increased as a result of a Change (as defined below),
then, within fifteen (15) days after written demand by such Lender, 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, its interest in the
Facility Letters of Credit or its obligation to make Loans hereunder or
participate in or issue Facility Letters of Credit 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. Without in any way
affecting the Borrower's obligation to pay compensation actually claimed by a
Lender under this SECTION 4.2, the Borrower shall have the right to replace any
Lender which has demanded such compensation with a replacement Lender acceptable
to Agent; provided, however, that no Monetary Default, other material Default or
any Event of Default shall then exist, and that Borrower notifies such Lender
that it has elected to replace such Lender and notifies such Lender and the
Agent of the identity of the proposed replacement Lender not more than sixty
(60) days after the date of such Lender's most recent demand for compensation
under this SECTION 4.2. The Lender being replaced shall assign its Percentage of
the Aggregate Commitment and its rights and obligations under this Facility to
the replacement

                                       33
<PAGE>

Lender in accordance with the requirements of SECTION 13.3 hereof and the
replacement Lender shall assume such Percentage of the Aggregate Commitment and
the related obligations under this Facility, all pursuant to an assignment
agreement substantially in the form of EXHIBIT D hereto. The purchase by the
replacement Lender shall be at par (plus all accrued and unpaid interest and any
other sums owed to such Lender being replaced hereunder) which shall be paid to
the Lender being replaced upon the execution and delivery of the assignment.

         4.3      AVAILABILITY OF LIBOR ADVANCES. If any Lender determines that
maintenance of any of its Loans bearing interest at the Adjusted LIBOR Rate at a
suitable Lending Installation would violate any applicable law, rule, regulation
or directive of any Governmental Authority having jurisdiction, the Agent shall
suspend by written notice to Borrower the availability of outstanding LIBOR
Advances and require any LIBOR Advances to be repaid. If the Required Lenders
determine that deposits of a type or maturity appropriate to match fund LIBOR
Advances are not available, the Agent shall suspend by written notice to
Borrower the availability of LIBOR Advances from and after the date of any such
determination. If the Required Lenders determine that an interest rate
applicable to a LIBOR Advance does not accurately reflect the cost of making a
LIBOR Advance, and, if for any reason whatsoever the provisions of SECTION 4.1
are inapplicable, the Agent shall suspend by written notice to Borrower the
availability of LIBOR Advances from and after the date of any such
determination.

         4.4      FUNDING INDEMNIFICATION. If any payment of a LIBOR Advance
occurs on a date which is not the last day of the LIBOR Interest Period, whether
because of acceleration, prepayment or otherwise, or a LIBOR Advance is not made
on the date specified by Borrower for any reason other than default by one or
more of the Lenders, Borrower will indemnify and hold harmless each Lender from
and against any loss, damage, expense or cost incurred by such Lender resulting
therefrom, including, without limitation, any loss, damage, expense or cost in
liquidating or employing deposits acquired to fund or maintain the LIBOR
Advance.

         4.5      TAXES.

                           (i)      All payments by the Borrower to or for the
                  account of any Lender or the Agent hereunder or under any Note
                  shall be made free and clear of and without deduction for any
                  and all Taxes. If the Borrower shall be required by law to
                  deduct any Taxes from or in respect of any sum payable
                  hereunder to any Lender or the Agent, (a) the sum payable
                  shall be increased as necessary so that after making all
                  required deductions (including deductions applicable to
                  additional sums payable under this SECTION 4.5) such Lender or
                  the Agent (as the case may be) receives an amount equal to the
                  sum it would have received had no such deductions been made,
                  (b) the Borrower shall make such deductions, (c) the Borrower
                  shall pay the full amount deducted to the relevant authority
                  in accordance with applicable law and (d) the Borrower shall
                  furnish to the Agent the original copy of a receipt evidencing
                  payment thereof within 30 days after such payment is made.

                           (ii)     In addition, the Borrower hereby agrees to
                  pay any present or future stamp or documentary taxes and any
                  other excise or property taxes, charges or similar levies
                  which arise from any payment made hereunder or under any

                                       34
<PAGE>

                  Note or from the execution or delivery of, or otherwise with
                  respect to, this Agreement or any Note ("OTHER TAXES").

                           (iii)    The Borrower hereby agrees to indemnify the
                  Agent and each Lender for the full amount of Taxes or Other
                  Taxes (including, without limitation, any Taxes or Other Taxes
                  imposed on amounts payable under this SECTION 4.5) paid by the
                  Agent or such Lender and any liability (including penalties,
                  interest and expenses) arising therefrom or with respect
                  thereto. Payments due under this indemnification shall be made
                  within 30 days of the date the Agent or such Lender makes
                  demand therefor pursuant to SECTION 4.6.

                           (iv)     Each Lender that is not incorporated under
                  the laws of the United States of America or a state thereof
                  (each a "NON-U.S. LENDER") agrees that it will, not more than
                  ten Business Days after the date of this Agreement, (i)
                  deliver to each of the Borrower and the Agent two duly
                  completed copies of United States Internal Revenue Service
                  Form W-8BEN or W-8ECI, certifying in either case that such
                  Lender is entitled to receive payments under this Agreement
                  without deduction or withholding of any United States federal
                  income taxes, and (ii) deliver to each of the Borrower and the
                  Agent a United States Internal Revenue Form W-8 or W-9, as the
                  case may be, and certify that it is entitled to an exemption
                  from United States backup withholding tax. Each Non-U.S.
                  Lender further undertakes to deliver to each of the Borrower
                  and the Agent (x) renewals or additional copies of such form
                  (or any successor form) on or before the date that such form
                  expires or becomes obsolete, and (y) after the occurrence of
                  any event requiring a change in the most recent forms so
                  delivered by it, such additional forms or amendments thereto
                  as may be reasonably requested by the Borrower or the Agent.
                  All forms or amendments described in the preceding sentence
                  shall certify that such Lender is entitled to receive payments
                  under this Agreement without deduction or withholding of any
                  United States federal income taxes, UNLESS an event (including
                  without limitation any change in treaty, law or regulation)
                  has occurred prior to the date on which any such delivery
                  would otherwise be required which renders all such forms
                  inapplicable or which would prevent such Lender from duly
                  completing and delivering any such form or amendment with
                  respect to it and such Lender advises the Borrower and the
                  Agent that it is not capable of receiving payments without any
                  deduction or withholding of United States federal income tax.

                           (v)      For any period during which a Non-U.S.
                  Lender has failed to provide the Borrower with an appropriate
                  form pursuant to clause (iv), above (unless such failure is
                  due to a change in treaty, law or regulation, or any change in
                  the interpretation or administration thereof by any
                  governmental authority, occurring subsequent to the date on
                  which a form originally was required to be provided), such
                  Non-U.S. Lender shall not be entitled to indemnification under
                  this SECTION 4.5 with respect to Taxes imposed by the United
                  States.

                           (vi)     Any Lender that is entitled to an exemption
                  from or reduction of withholding tax with respect to
                  payments under this Agreement or any Note pursuant to the
                  law of any relevant jurisdiction or any treaty shall deliver
                  to the

                                       35
<PAGE>

                  Borrower (with a copy to the Agent), at the time or
                  times prescribed by applicable law, such properly completed
                  and executed documentation prescribed by applicable law as
                  will permit such payments to be made without withholding or
                  at a reduced rate following receipt of such documentation.

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

         4.6      LENDER STATEMENTS; SURVIVAL OF INDEMNITY. To the extent
reasonably possible, each Lender shall designate an alternate Lending
Installation with respect to its LIBOR Advances to reduce any liability of
Borrower to such Lender under SECTIONS 4.1, 4.2 and 4.5 or to avoid the
unavailability of a LIBOR Advance, 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 SECTIONS 4.1, 4.2, 4.4 or 4.5
hereof. Such written statement shall set forth in reasonable detail the
calculations upon which such Lender determined such amount and shall be final,
conclusive and binding on Borrower in the absence of manifest error.
Determination of amounts payable under such Sections in connection with a LIBOR
Advance shall be calculated as though each Lender funded its LIBOR Advance
through the purchase of a deposit of the type and maturity corresponding to the
deposit used as a reference in determining the Adjusted LIBOR Rate applicable to
such Advance, 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 Borrower of the written statement. The obligations of Borrower
under SECTIONS 4.1, 4.2, 4.4 and 4.5 hereof shall survive payment of the
Obligations and termination of this Agreement.

         4.7      REMOVAL OR REPLACEMENT OF A LENDER.

                  (a)      Anything contained in this Agreement to the contrary
notwithstanding, in the event that:

                           (i)      (1) any Lender (an "Increased-Cost Lender")
                  shall give notice to Borrower that such Lender is entitled to
                  receive payments under Section 4.5, (2) the circumstances
                  which entitle such Lender to receive such payments shall
                  remain in effect, and (3) such Lender shall fail to withdraw
                  such notice within ten Business Days after Borrower's request
                  for such withdrawal; or

                                       36
<PAGE>

                           (ii)     any Lender shall be a Defaulting Lender;
                  then,   and in each such case, Borrower shall have the right,
                  at its option, to remove or replace the applicable Increased-
                  Cost Lender or Defaulting Lender (the "Terminated Lender") to
                  the extent permitted by this Section 4.7.

                  (b)      Borrower may, by giving written notice to the Agent
and any Terminated Lender:

                           (i)      elect to (a) terminate the Commitment, if
                  any, of such Terminated Lender upon receipt by such Terminated
                  Lender of such notice and (b) prepay on the date of such
                  termination any outstanding Loans made by such Terminated
                  Lender, at par, together with accrued and unpaid interest
                  thereon and any other amounts payable to such Terminated
                  Lender hereunder pursuant to Section 4.5 or otherwise;
                  PROVIDED that, in the event such Terminated Lender has any
                  Loans outstanding at the time of such termination, the written
                  consent of Agent and Required Lenders (which consent shall not
                  be unreasonably withheld or delayed) shall be required in
                  order for Borrower to make the election set forth in this
                  clause (i); or

                           (ii)     elect to cause such Terminated Lender (and
                  such Terminated Lender hereby irrevocably agrees) to assign
                  its outstanding Loans, at par, and its Commitment, if any, in
                  full to one or more Eligible Assignees (each a "Replacement
                  Lender") in accordance with the provisions of Section 13.3 (it
                  being understood that neither Agent nor such Terminated Lender
                  shall have any obligation to solicit or otherwise identify any
                  potential Replacement Lender); PROVIDED that, on the date of
                  such assignment, Borrower shall pay any amounts payable to
                  such Terminated Lender pursuant to Section 4.5 or otherwise as
                  if it were a prepayment; and PROVIDED, FURTHER that, if such
                  Terminated Lender fails to enter into an Assignment Agreement
                  with any applicable Replacement Lender in accordance with the
                  provisions of Section 13.3 as contemplated by the foregoing
                  provisions of this Section 4.8, it shall be deemed to have so
                  entered into such Assignment Agreement;

         PROVIDED that Borrower may not make either of the elections set forth
in clauses (i) or (ii) above with respect to any Terminated Lender that has
issued any Facility Letter of Credit unless, prior to the effectiveness of such
election, Borrower shall have caused each outstanding Facility Letter of Credit
issued by such Terminated Lender to be cancelled or replaced.

                  (c)      Upon the prepayment of all amounts owing to any
Terminated Lender and the termination of such Terminated Lender's Commitment, if
any, pursuant to clause (i) of Section 4.7(b), (i) this Agreement shall be
deemed modified to reflect any corresponding changes in the Commitments and (ii)
such Terminated Lender shall no longer constitute a "Lender" for purposes of
this Agreement; PROVIDED that any rights of such Terminated Lender to
indemnification under this Agreement shall survive as to such Terminated Lender.

                                   ARTICLE VI

                         REPRESENTATIONS AND WARRANTIES

         Borrower hereby represents and warrants that:

         6.1      EXISTENCE. Attached hereto as SCHEDULE 6.1 (as updated from
time to time in accordance with this Agreement) is a table showing, for each
Credit Party, its organizational form (e.g., corporation, partnership, limited
liability company, etc.), state of organization, state in which its principal
place of business is located, and owner(s) of its Capital Stock and their
percentage ownership interests. Each Credit Party is an entity of the type
indicated for such Credit Party on SCHEDULE 6.1 (as updated from time to time)
duly organized and validly existing under the laws of the state of its
organization as indicated on SCHEDULE 6.1 (as updated from time to time), with
its principal place of business in the state indicated for such Credit Party on
SCHEDULE 6.1 (as updated from time to time), and is duly qualified as a foreign
entity, properly licensed (if required), in good standing and has all requisite
authority to conduct its business in each jurisdiction in which it owns any
Property and, except where the failure to be so qualified or to obtain such
authority would not have a Material Adverse Effect, in each other jurisdiction
in which the nature of its business or activities requires such qualification or
authority. Each Subsidiary of each Credit Party, if any, is duly organized,
validly existing and in good standing under the laws of its jurisdiction of
organization and has all requisite authority to conduct its business in each
jurisdiction in which it owns any Property, and except where the failure to be
so

                                       40
<PAGE>

qualified or to obtain such authority would not have a Material Adverse Effect,
in each other jurisdiction in which the nature of its business or activities
requires such qualification.

         6.2      CORPORATE/PARTNERSHIP POWERS. The execution, delivery and
performance of the Loan Documents required to be delivered by each Credit Party
hereunder are within the power and authority of such entity and have been duly
authorized by all requisite action, and are not in conflict with the terms of
any organizational instruments of such entity, or any instrument or agreement to
which such Credit Party is a party or by which such Credit Party or any of its
respective assets may be bound or affected.

         6.3      POWER OF OFFICERS. The officers of each Credit Party executing
the Loan Documents required to be delivered by such entities or by the Borrower
hereunder have been duly elected or appointed and were fully authorized to
execute the same at the time each such agreement, certificate or instrument was
executed.

         6.4      GOVERNMENT AND OTHER APPROVALS. No approval, consent,
exemption or other action by, or notice to or filing with, any governmental
authority is necessary in connection with the execution, delivery or performance
of any of the Loan Documents by any of the Credit Parties. No other consent to
or approval of the transactions contemplated hereunder is required from any
ground lessor, mortgagee, beneficiary under a deed of trust or any other Person,
except as has been delivered to the Lenders on or before the Agreement Execution
Date.

         6.5      SOLVENCY. Immediately after the Agreement Execution Date and
immediately following the making of each Advance and after giving effect to the
application of the proceeds of such Advance, each of the Credit Parties will be
Solvent.

         6.6      COMPLIANCE WITH LAWS AND AGREEMENTS. There is no judgment,
decree or order or any law, rule or regulation of any court or governmental
authority binding on any of the Credit Parties or any of their respective assets
which would be violated or contravened by the execution, delivery or performance
of the Loan Documents. The Credit Parties and their respective Property and
other assets are in substantial compliance with applicable laws, and with all
material leases, licenses and other agreements to which any Credit Party is a
party or by which such Credit Party or any of its assets is bound. No other
party to any such lease, license or other agreement is in default thereunder in
any material respect.

         6.7      ENFORCEABILITY OF AGREEMENT. This Agreement and each of the
other Loan Documents is (or, when fully executed and delivered, will be) the
legal, valid and binding agreement of each of the Credit Parties thereto,
enforceable against each such Credit Party in accordance with its respective
terms, except to the extent that such enforcement may be limited by applicable
bankruptcy, insolvency, reorganization or other similar laws affecting the
rights of creditors generally.

         6.8      TITLE TO PROPERTY. Borrower or its Subsidiaries has fee simple
title (subject only to Permitted Liens) to the Property and assets reflected in
Borrower's consolidated financial statements most recently delivered to the
Agent as owned by it or any such Subsidiary, free and clear of Liens except for
the Permitted Liens. Neither the execution, delivery nor performance of the Loan
Documents required by the Credit Parties will result in the creation of any Lien
on the Property or such assets. Borrower and its Subsidiaries either own, or
have entered into valid

                                       41
<PAGE>

leases, licenses and other agreements for, all assets, services and facilities
necessary for the conduct of their respective businesses and the operation of
their respective assets.

         6.9      LITIGATION. There are no suits, arbitrations, claims,
disputes or other proceedings (including, without limitation, any civil,
criminal, administrative or environmental proceedings), pending or, to the best
of Borrower's knowledge after due inquiry, threatened against or affecting the
Borrower, any of the other Credit Parties or any of the Property, the adverse
determination of which individually or in the aggregate could reasonably be
expected to have a Material Adverse Effect, except as disclosed on SCHEDULE 6.9
hereto.

         6.10     EVENTS OF DEFAULT. No Default or Event of Default has occurred
and is continuing or would result from the incurring of obligations by any of

of the date of such notification), exceeds $2,000,000 or requires payments
exceeding $1,000,000 per annum, or (ii) such Plan is in reorganization or is

     10.13 FAILURE TO SATISFY JUDGMENTS. Any of the Borrower, any Guarantor or
any Material Subsidiary shall fail within sixty (60) days to pay, bond or
otherwise discharge any judgments or orders for the payment of money in an

                                   ARTICLE XI

                  ACCELERATION, WAIVERS AMENDMENTS AND REMEDIES

     11.1 ACCELERATION. If any Event of Default described in SECTION 10.10
hereof occurs, the obligation of the Lenders to make Advances hereunder and of
the Issuing Bank to issue Facility Letters of Credit shall automatically
terminate and the Obligations shall immediately become due and payable. If any
other Event of Default described in ARTICLE X hereof shall have occurred and be
continuing, the Agent may (and upon demand of the Required Lenders, shall)
notify Borrower that such obligation to make Advances and to issue Facility
Letters of Credit has terminated and the Obligations shall immediately become
due and payable.

     In addition to the foregoing, following the occurrence of and during the
continuance of an Event of Default and so long as any Facility Letter of Credit
has not been fully drawn and has not been cancelled or expired by its terms,
upon written demand by the Required Lenders, the Borrower shall deposit in the
Letter of Credit Collateral Account cash in an amount equal to the aggregate
undrawn face amount of all outstanding Facility Letters of Credit and all fees
and




                                       59
<PAGE>

other amounts due or which may become due with respect thereto. The Borrower
shall have no control over funds in the Letter of Credit Collateral Account,
which funds shall be invested by the Agent from time to time in its discretion
in certificates of deposit of Bank One having a maturity not exceeding thirty
(30) days. Such funds shall be promptly applied by the Agent to reimburse the
Issuing Bank for drafts drawn from time to time under the Facility Letters of
Credit. Such funds, if any, remaining in the Letter of Credit Collateral Account
following the payment of all Obligations in full shall, unless the Agent is
otherwise directed by a court of competent jurisdiction, be promptly paid over
to the Borrower.

     11.2 PRESERVATION OF RIGHTS; AMENDMENTS. No delay or omission of the
Lenders in exercising any right under the Loan Documents shall impair such right
or be construed to be a waiver of any Default or Event of Default or an
acquiescence therein, and the making of an Advance notwithstanding the existence
of a Default or Event of Default or the inability of the Borrower to satisfy any
conditions precedent to such Advance 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, release or other variation of the terms, conditions or
provisions of the Loan Documents whatsoever shall be valid unless in writing
signed by the Agent and the number of Lenders required hereunder 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 may be exercised
concurrently or successively, and all shall be available to the Lenders until
the Obligations have been paid in full.

                                   ARTICLE XII

                                    THE AGENT

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

     12.2 POWERS. The Agent shall have and may exercise such powers under the
Loan Documents as are specifically delegated to the Agent by the terms of each
thereof, together with such powers as are reasonably incidental thereto (but
subject to SECTION 14.13 below). The Agent shall have no implied duties,
obligations or liabilities to the Lenders, or any obligation to



                                       60
<PAGE>

the Lenders to take any action thereunder except any action specifically
provided by the Loan Documents to be taken by the Agent. Only Agent may perform
the duties reserved to it under the Loan Documents and no Lender shall act or
purport to act on behalf of the other Lenders or Agent on any such matters.
Without limiting the generality of the foregoing:

          (a) Agent shall have the exclusive right to collect from Borrower and
any Guarantor, or third parties, on account of the Facility, including,
principal, interest, fees, protective advances and prepayment premiums (if any),
whether such sums are received directly from Borrower, Guarantor, or any other
Persons, or are obtained by right of offset by Agent of any kind, or by
enforcement of the Loan Documents. Agent will receive and hold all collections
with respect to the Loan for the benefit of the Lenders in accordance with their
Percentages or as otherwise provided herein.

          (b) If any Lender shall receive any payments or property in connection
with the Facility (whether or not voluntary), from any Person other than Agent,
such Lender shall transfer to Agent all such payments or property within one
Business Day of receipt.

          (c) No Lender shall independently initiate any judicial action or
other proceeding against Borrower or any Guarantor with respect to the Facility.

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

     12.4 NO RESPONSIBILITY FOR LOANS, RECITALS, ETC. Neither the Agent nor any
of its directors, officers, agents or employees shall be responsible for or have
any duty to ascertain, inquire into, or verify (i) any statement, warranty or
representation made in connection with any Loan Document or any borrowing
hereunder; (ii) the performance or observance of any of the covenants or
agreements of any obligor under any Loan Document; (iii) the satisfaction of any
condition specified in ARTICLE V, except receipt of items required to be
delivered to the Agent; or (iv) the validity, effectiveness or genuineness of
any Loan Document or any other instrument or writing furnished in connection
therewith.

     12.5 ACTION ON INSTRUCTIONS OF LENDERS. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, hereunder and under any
other Loan Document in accordance with written instructions signed by the
Required Lenders (or, in the case of any waiver or amendment listed in SECTION
14.13(a) hereof, all of the Lenders) and such instructions and any action taken
or failure to act pursuant thereto shall be binding on all of the Lenders and on
all holders of Notes. The Agent shall be fully justified in failing or refusing
to take any action hereunder and under any other Loan Document unless it shall
first receive such advise or concurrence, if it so requests, of the Required
Lenders and shall first be indemnified to its satisfaction by the Lenders pro
rata against any and all liability, cost and expense that it may incur by reason
of taking or continuing to take any such action.

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



                                       61
<PAGE>

attorneys-in-fact selected by it with reasonable care. The Agent shall be
entitled to engage and rely upon advice of legal counsel (including the
Borrower's counsel), independent accountants and other professionals and experts
selected by the Agent concerning all matters pertaining to the agency hereby
created and its duties hereunder and under any other Loan Document. The Borrower
and the Lenders agree that the Agent may delegate any of its duties under this
Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate's
directors, officers, agents and employees) which performs duties in connection
with this Agreement shall be entitled to the same benefits of the
indemnification, waiver and other protective provisions to which the Agent is
entitled under Articles XII and XIV.

     12.7 RELIANCE ON DOCUMENTS. The Agent shall be entitled to rely upon any
Note, writing, notice, consent, certificate, facsimile, affidavit, letter,
telegram, statement, paper, document or other communication believed by it to be
genuine and correct and to have been signed, sent or otherwise communicated by
the proper person or persons.

     12.8 AGENT'S REIMBURSEMENT AND INDEMNIFICATION. The Lenders agree to
reimburse and indemnify upon demand the Agent ratably in accordance with their
respective Percentages (i) for any amounts not reimbursed by the Borrower for
which the Agent is entitled to reimbursement by the Borrower under the Loan
Documents, (ii) for any other expenses (including reasonable attorneys' fees)
incurred by the Agent on behalf of the Lenders, in connection with the
preparation, execution, delivery, administration, modification and enforcement
of the Loan Documents, if not paid by Borrower, and (iii) for any liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind and nature whatsoever which may be imposed
on, incurred by or asserted against the Agent in any way relating to or arising
out of the Loan Documents or any other document delivered in connection
therewith or the transactions contemplated thereby, or the enforcement of any of
the terms thereof or of any such other documents, provided that no Lender shall
be liable for any of the foregoing to the extent they arise from the gross
negligence or willful misconduct of the Agent. Each Lender shall indemnify the
Agent and the other Lenders with respect to claims, liabilities, damages, costs,
losses and expenses (including, without limitation, attorneys' fees) arising
from or relating to the failure of such indemnifying Lender to satisfy its
obligations under this Agreement and the other Loan Documents.

     12.9 RIGHTS AS A LENDER. With respect to the Commitment, Advances made by
it, the Note issued to it and otherwise, the Agent shall have the same rights
and powers hereunder and under any other Loan Document as any Lender and may
exercise the same as though it were not the Agent, and the term "Lender" or
"Lenders" shall, unless the context otherwise indicates, include the Agent in
its capacity as a Lender. The Agent, in its capacity as a Lender, may accept
deposits from, lend money to, and generally engage in any kind of trust, debt,
equity or other transaction, in addition to those contemplated by this Agreement
or any other Loan Document, with the Borrower or any of its Subsidiaries in
which the Borrower or such Subsidiary is not restricted hereby from engaging
with any other Person. The Lenders acknowledge that Agent and its Affiliates now
or in the future may have banking or other financial relationships, including
being an agent on other loans, with Borrower and its Affiliates, as though Bank
One were not Agent hereunder and without notice to or consent of the Lenders.
Each Lender hereby expressly waives any objection to such actual or potential
conflict of interest. The Lenders acknowledge that in the course of such
activities, Bank One or its Affiliates may receive



                                       62
<PAGE>

information regarding Borrower or its Affiliates and acknowledge that Agent
shall be under no obligation to provide such information to them, whether or not
confidential.

     12.10 LENDER CREDIT DECISION. Each Lender acknowledges that neither the
Agent nor any of its agents has made any representation or warranty to such
Lender and that no action or statement hereafter made or taken by the Agent or
any of its agents shall be deemed to be representation or warranty by the Agent
to such Lenders. Each Lender further acknowledges that it has, independently and
without reliance upon the Agent or any other Lender and based on the financial
statements prepared by the Borrower and such other documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement and the other Loan Documents. Each Lender also acknowledges
that it will, independently and without reliance upon the Agent 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 analysis and decisions in taking or
not taking action under this Agreement and the other Loan Documents.

     12.11 SUCCESSOR AGENT. Each Lender agrees that Bank One shall serve as
Agent at all times during the term of this Facility, except that Bank One may
resign as Agent at any time, in its sole discretion, upon thirty (30) days'
prior written notice to the Lenders and Borrower. Bank One (or any successor
Agent) may be removed as Agent for good cause by written notice received by
Agent from the Required Lenders. Upon any such resignation or removal, the
Required Lenders shall have the right to appoint, on behalf of the Borrower and
the Lenders, a successor Agent. If no successor Agent shall have been so
appointed by the Required Lenders and shall have accepted such appointment
within thirty (30) days after the retiring Agent's giving notice of resignation
or receiving notice of removal, 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
(including the right to receive any fees for performing such duties which accrue
thereafter), 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 XII shall
continue in effect for its benefit and that of the other Lenders 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.

     12.12 NOTICE OF DEFAULTS. If a Lender becomes aware of a Default or Event
of Default, such Lender shall notify the Agent of such fact. Upon receipt of
such notice that a Default or Event of Default has occurred, the Agent shall
notify promptly each of the Lenders of such fact. Except for Defaults in the
payment of principal, interest and fees payable to Agent for the account of the
Lenders and such other Obligations for which Agent is expressly responsible for
determining Borrower's compliance, Agent shall not be deemed to have knowledge
or notice of the occurrence of any Default or Event of Default, unless Agent
shall have received written notice from a Lender or Borrower referring to the
Loan, describing such Default or Event of Default and stating that such notice
is a "notice of default". Agent will promptly notify the Lenders of any such
payment Defaults or Defaults in such other Obligations and of its receipt of any
such notice. Agent shall take action with respect to such Default or Event of
Default in accordance with the provisions of this Agreement and the Loan
Documents.

                                       63
<PAGE>

     12.13 REQUESTS FOR APPROVAL. If the Agent requests in writing the consent
or approval of a Lender, whether or not such consent or approval is required
hereunder (and no such requirement shall be inferred from any such request),
such Lender shall respond and either approve or disapprove definitively in
writing to the Agent within seven (7) Business Days (or sooner if such notice
specifies a shorter period based on Agent's good faith determination that
circumstances warrant an earlier response) after such written request from the
Agent. If any Lender does not so respond, that Lender shall be deemed to have
disapproved the request. Upon request, the Agent shall notify the Lenders which
Lenders, if any, failed to respond to a request for approval.

     12.14 COPIES OF DOCUMENTS. Agent shall promptly deliver to each of the
Lenders copies of all notices of default and other formal notices sent to or
received by the Agent pursuant to SECTION 15.1 of this Agreement. Within fifteen
(15) Business Days after a request by a Lender to the Agent for other documents
furnished to the Agent by the Borrower, the Agent shall provide copies of such
documents to such Lender except where this Agreement obligates Agent to provide
copies in a shorter period of time.

     12.15 DEFAULTING LENDERS. At such time as a Lender becomes a Defaulting
Lender, such Defaulting Lender's right to vote on matters which are subject to
the consent or approval of the Required Lenders, such Defaulting Lender or all
Lenders shall be immediately suspended until such time as the Lender is no
longer a Defaulting Lender. If a Defaulting Lender has failed to fund its
Percentage of any Advance and until such time as such Defaulting Lender
subsequently funds its Percentage of such Advance, all Obligations owing to such
Defaulting Lender hereunder shall be subordinated in right of payment, as
provided in the following sentence, to the prior payment in full of all
principal of, interest on and fees relating to the Loans funded by the other
Lenders in connection with any such Advance in which the Defaulting Lender has
not funded its Percentage (such principal, interest and fees being referred to
as "Senior Loans" for the purposes of this section). All amounts paid by the
Borrower and otherwise due to be applied to the Obligations owing to such
Defaulting Lender pursuant to the terms hereof shall be distributed by the Agent
to the other Lenders in accordance with their respective Percentages
(recalculated for the purposes hereof to exclude the Defaulting Lender) until
all Senior Loans have been paid in full. At that point, the "Defaulting Lender"
shall no longer be deemed a Defaulting Lender. After the Senior Loans have been
paid in full equitable adjustments will be made in connection with future
payments by the Borrower to the extent a portion of the Senior Loans had been
repaid with amounts that otherwise would have been distributed to a Defaulting
Lender but for the operation of this SECTION 12.15. This provision governs only
the relationship among the Agent, each Defaulting Lender and the other Lenders;
nothing hereunder shall limit the obligation of the Borrower to repay all Loans
in accordance with the terms of this Agreement. The provisions of this SECTION
12.15 shall apply and be effective regardless of whether a Default occurs and is
continuing, and notwithstanding (i) any other provision of this Agreement to the
contrary, (ii) any instruction of the Borrower as to its desired application of
payments or (iii) the suspension of such Defaulting Lender's right to vote on
matters as provided above.

     12.16 BORROWER'S DEFAULT; ENFORCEMENT. Upon the occurrence of an Event of
Default under any Loan Document, the Required Lenders shall have the right, upon
written notice to Agent, to require that Agent exercise the rights of the
Lenders as directed by the Required Lenders; provided, however, that the Lenders
shall indemnify, exonerate and hold Agent



                                       64
<PAGE>

harmless from and against any and all claims, losses, liabilities, damages and
costs (including reasonable legal fees) incurred by Agent as a result of any
such exercise of rights at the direction of the Lenders and not resulting from
the gross negligence or willful misconduct of Agent.

     12.17 WORKOUT. If Borrower is in material default under the Loan Documents
and has not cured the default within any applicable cure period, Agent may
declare by written notice to the Lenders that the Loan is "in workout" (the
"NOTICE OF WORKOUT"). The Lenders acknowledge that workouts of defaulted loans
usually are resolved by either a borrower cure of the default; or a restructure
of or other modification to the loan; or by exercising remedies; and that it is
in the interest of the Lenders to attain a resolution within a reasonable period
of time. Therefor the Lenders agree that if, after 90 days from the date of
Agent's Notice of Workout, there has been neither a cure of the default(s), nor
a restructure nor other modification executed, nor exercise of the Lenders'
remedies hereunder, then (unless otherwise directed by the Required Lenders)
Agent on behalf of the Lenders shall sue Borrower and any Guarantors for
collection of amounts owing to the Lenders, subject to and in accordance with
advice of Agent's counsel. Notwithstanding any action by Agent under this
SECTION 12.17 Agent shall follow the direction of the Required Lenders under
SECTION 12.16 above at any time. Nevertheless, unless and until the Required
Lenders shall direct Agent to the contrary, Agent shall have the right but not
the obligation to take such action as it may deem appropriate to preserve the
rights of the Lenders to recover any amounts owing under the Loan Documents,
without the consent of the Required Lenders.

     12.18 BANKRUPTCY OF BORROWER. In the event of a bankruptcy by Borrower, the
Lenders shall act through Agent to petition the court, make any motion for
relief from the automatic stay, participate in any appropriate creditors'
committee, vote on a plan of reorganization or pursue other remedies or actions
in accordance with the approval of the Required Lenders or all of the Lenders,
as circumstances dictate.

     12.19 RELATIONSHIP OF PARTIES. This Agreement is not intended to establish
a partnership or joint venture between Agent and the Lenders. The provisions of
the Loan Documents regarding the relationships among Agent and the Lenders and
this ARTICLE XII is intended solely to facilitate co-lending relationships among
the Lenders for the Facility. No security or investment contract under any
federal or state law is intended to be created among the Lenders or between
Agent and the Lenders. The execution of this Agreement, the performance of the
terms thereof, and the Lenders' purchase of and ownership interest in the
Facility and the Loan Documents shall not constitute any Lender as owner,
purchaser or seller of any security (as that term is defined in the Securities
Act of 1933 or the Securities Exchange Act of 1934) issued, owned, purchased or
sole by Bank One or any of its Subsidiaries or Affiliates, either as principal
or as agent for Borrower. Each Lender is purchasing and acquiring legal and
equitable ownership of its Percentage and is not making a loan to Bank One, and
no debtor-creditor relationship exists between them as a result of this
Agreement.

     12.20 COUNSEL. The Lenders acknowledge that Agent's counsel has represented
and shall represent only Agent, in its capacity as Agent and Lender, in
connection with the Loan Documents and this Agreement. Each other Lender shall
retain independent legal counsel regarding all such matters, documents and
agreements. After an Event of Default, the Lenders shall enter into a joint
privilege agreement regarding the exchange of information that is or may be
subject to attorney-client privilege or related privileges. Agent's counsel
shall prepare such



                                       65
<PAGE>

joint privilege agreement, subject to the approval of all of the Lenders which
approval shall not be unreasonably withheld by any Lender.

                                  ARTICLE XIII

                BENEFIT OF AGREEMENT; PARTICIPATIONS; ASSIGNMENTS

     13.1 SUCCESSORS AND ASSIGNS. The terms and provisions of the Loan Documents
shall be binding upon and inure to the benefit of Borrower and the Lenders and
their respective successors and assigns, except that the Borrower shall not have
the right to assign its rights or obligations under the Loan Documents without
the consent of all the Lenders and any assignment by any Lender must be made in
compliance with SECTION 13.3. 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 13.3 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.

     13.2 PARTICIPATIONS.

          (a) 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"), in an amount not less
than $5,000,000 with $1,000,000 increments thereafter, participating interests
in any Advance owing to such Lender, any Note held by such Lender, any
Commitment of such Lender or any other interest of such Lender under the Loan
Documents. In the event of any such sale by a Lender of participating interests
to a Participant, such Lender's obligations under the Loan Documents shall
remain unchanged, such Lender shall remain solely responsible to the other
parties hereto for the performance of such obligations, such Lender shall remain
the holder of any such Note for all purposes under the Loan Documents, all
amounts payable by Borrower under this Agreement shall be determined as if such
Lender had not sold such participating interests, and Borrower and the Agent and
the other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under the Loan Documents.

          (b) VOTING RIGHTS. Each Lender shall retain the sole right to vote its
Percentage of the Aggregate Commitment, without the consent of any Participant,
for the approval or disapproval of any amendment, modification or waiver of any
provision of the Loan Documents, provided that such Lender may grant such
Participant the right to approve any amendment, modification or waiver which
forgives principal, interest or fees or reduces the interest rate or fees
payable hereunder, postpones any date fixed for any regularly-scheduled payment
of principal of or interest on the Obligations, releases collateral beyond any
releases expressly provided for herein or extends the Maturity Date.

          (c) BENEFITS OF SET-OFF. The Borrower agrees that each Participant
which has previously advised the Borrower in writing of its purchase of a
participation in a Lender's interest in its Loans shall be deemed to have the
right of setoff provided in SECTION 14.15 in



                                       66
<PAGE>

respect of its participating interest in amounts owing under the Loan Documents
to the same extent as if the amount of its participating interest were owing
directly to it as a Lender under the Loan Documents. Each Lender shall retain
the right of setoff provided in SECTION 14.15 with respect to the amount of
participating interests sold to each Participant, provided that such Lender and
Participant may not each setoff amounts against the same portion of the
Obligations, so as to collect the same amount from the Borrower twice. The
Lenders agree to share with each Participant, and each Participant, by
exercising the right of setoff provided in SECTION 14.15, 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 14.15 as if each
Participant were a Lender.

     13.3 ASSIGNMENTS.

          (a) PERMITTED ASSIGNMENTS. Any Lender may, with the prior written
consent of Agent and Borrower (which consents shall not be unreasonably withheld
or delayed), in accordance with applicable law, at any time assign to one or
more Eligible Assignees (collectively, "PURCHASERS"), in an amount not less than
$5,000,000 with $1,000,000 increments thereafter, all or any part of its rights
and obligations under the Loan Documents, except that no consent of Borrower
shall be required if any Monetary Default, other material Default or Event of
Default has occurred and is continuing and that no consent of Agent or Borrower
shall ever be required for (i) any assignment to a Person directly or indirectly
controlling, controlled by or under direct or indirect common control with the
assigning Lender or (ii) the pledge or assignment by a Lender of such Lender's
Note and other rights under the Loan Documents to any Federal Reserve Bank in
accordance with applicable law. Such assignments and assumptions shall be
substantially in the form of EXHIBIT D hereto. The Borrower shall execute any
and all documents which are customarily required by such Lender (including,
without limitation, a replacement promissory note or notes in the forms provided
hereunder) in connection with any such assignment, but Borrower shall not be
obligated to pay any fees and expenses incurred by any Lender in connection with
any assignment pursuant to this Section. Any Lender selling all or any part of
its rights and obligation hereunder in a transaction requiring the consent of
the Agent shall pay to the Agent a fee of $3,500.00 per assignee to reimburse
Agent for its involvement in such assignment (except in connection with an
assignment to a branch office or Affiliate of such Lender).

          (b) EFFECTIVE DATE OF ASSIGNMENT. Upon delivery to the Agent of a
notice of assignment executed by the assigning Lender and the Purchaser,
together with any consents and fee required by SECTION 13.3.(a), such assignment
shall become effective on the effective date specified in such notice of
assignment. The notice of assignment shall contain an undertaking by the
Purchaser to be bound as a Lender by this Agreement and the other Loan Documents
with the same force and effect as if it were an original signatory hereto, and a
representation by the Purchaser to the effect that none of the consideration
used to make the purchase of the Commitment and the Loan under the applicable
assignment agreement are "plan assets" as defined under ERISA and that the
rights and interests of the Purchaser in and under the Loan Documents will not
be "plan assets" under ERISA, all in form and content satisfactory to the Agent.
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 Borrower, the



                                       67
<PAGE>

Lenders or the Agent shall be required to release the transferor Lender with
respect to the percentage of the Commitment and Advances assigned to such
Purchaser. Upon the consummation of any assignment to a Purchaser pursuant to
this SECTION 13.3.2, the transferor Lender, the Agent and 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.

     13.4 DISSEMINATION OF INFORMATION. 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 Borrower and the Guarantors. Each Transferee
shall agree to keep confidential any such information which is not publicly
available.

     13.5 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
all applicable provisions of the Code with respect to withholding and other tax
matters.

                                   ARTICLE XIV

                               GENERAL PROVISIONS

     14.1 SURVIVAL OF REPRESENTATIONS. All representations and warranties
contained in this Agreement shall survive delivery of the Notes and the making
of the Advances herein contemplated.

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

     14.3 TAXES. Any recording and other taxes (excluding franchise, income or
similar taxes) or other similar assessments or charges payable or ruled payable
by any governmental authority incurred in connection with the consummation of
the transactions contemplated by this Agreement shall be paid by the Borrower,
together with interest and penalties, if any.

     14.4 HEADINGS. Section headings in the Loan Documents are for convenience
of reference only, and shall not govern the interpretation of any of the
provisions of the Loan Documents.

     14.5 NO THIRD PARTY BENEFICIARIES. 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.

     14.6 EXPENSES: INDEMNIFICATION. Subject to the provisions of this
Agreement, Borrower will pay upon demand (a) all out-of-pocket costs and
expenses incurred by the Agent or the Arranger (including the reasonable fees,
out-of-pocket expenses and other reasonable expenses of counsel, which counsel
may be employees of Agent or Arranger) in connection with



                                       68
<PAGE>

the preparation, execution and delivery of this Agreement, the Notes, the Loan
Documents and any other agreements or documents referred to herein or therein
and any amendments thereto, (b) all out-of-pocket costs and expenses incurred by
the Agent and the Lenders (including the reasonable fees, out-of-pocket expenses
and other reasonable expenses of counsel for the Agent and each of the other
Lenders) in connection with the enforcement and protection of the rights of the
Lenders under this Agreement, the Notes, the Loan Documents or any other
agreement or document referred to herein or therein; provided, however, that the
expenses of counsel for which Borrower is obligated under this subsection (b)
shall be limited to the reasonable non-duplicative expenses of (A) a single
outside law firm representing Agent, and (B) a single outside law firm
representing all of the other Lenders as a group (which may or may not be the
same law firm representing Agent), and (c) all reasonable and customary costs
and expenses of periodic audits by the Agent's personnel of the Borrower's books
and records provided that prior to an Event of Default, Borrower shall not be
required to pay for more than one such audit during any year. The Borrower
further agrees to indemnify the Lenders, their directors, officers and employees
against all losses, claims, damages, penalties, judgments, liabilities and
reasonable expenses (including, without limitation, all expenses of litigation
or preparation therefor, whether or not any Lender is a party thereto) which any
of them may pay or incur arising out of or relating to this Agreement, the other
Loan Documents, the transactions contemplated hereby or the direct or indirect
application or proposed application of the proceeds of any Advance hereunder,
except that the foregoing indemnity shall not apply to a Lender to the extent
that any losses, claims, etc. are the result of such Lender's gross negligence
or willful misconduct. The obligations of the Borrower under this Section shall
survive the termination of this Agreement.

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

     14.8 NONLIABILITY OF THE LENDERS. The relationship between the Borrower and
the Lenders shall be solely that of borrower and lender. Neither the Agent nor
the Lenders shall have any fiduciary responsibilities to the Borrower. Neither
the Agent nor the Lenders undertake responsibility to the Borrower to review or
inform the Borrower of any matter in connection with any phase of the Borrower's
business or operations.

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

     14.10 CONSENT TO JURISDICTION. THE BORROWER HEREBY IRREVOCABLY SUBMITS TO
THE NON-EXCLUSIVE JURISDICTION OF ANY UNITED STATES FEDERAL OR ILLINOIS STATE
COURT SITTING IN CHICAGO, ILLINOIS IN ANY ACTION OR PROCEEDING ARISING OUT OF OR
RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER HEREBY IRREVOCABLY AGREES THAT
ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED
IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION


                                       69
<PAGE>

IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR
PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM.
NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE LENDERS TO BRING PROCEEDINGS AGAINST
THE BORROWER IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY
THE BORROWER AGAINST THE LENDERS OR ANY AFFILIATE OF THE LENDERS INVOLVING,
DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR
CONNECTED WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN CHICAGO,
ILLINOIS.

     14.11 WAIVER OF JURY TRIAL. EACH OF THE BORROWER, AGENT AND LENDERS HEREBY
KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE ANY RIGHT THAT IT MAY HAVE TO A
TRIAL BY JURY IN ANY LITIGATION ARISING IN ANY WAY IN CONNECTION WITH THIS
AGREEMENT, THE NOTES, OR ANY OF THE OTHER LOAN DOCUMENTS, THE LOAN, OR ANY OTHER
STATEMENTS OR ACTIONS OF ANY PARTY HERETO. EACH SUCH ENTITY ACKNOWLEDGES THAT IT
HAS BEEN REPRESENTED IN THE SIGNING OF THIS AGREEMENT AND IN THE MAKING OF THIS
WAIVER BY INDEPENDENT LEGAL COUNSEL SELECTED OF ITS OWN FREE WILL, AND THAT IT
HAS DISCUSSED THIS WAIVER WITH SUCH LEGAL COUNSEL. BORROWER FURTHER ACKNOWLEDGES
THAT (i) IT HAS READ AND UNDERSTANDS THE MEANING AND RAMIFICATIONS OF THIS
WAIVER, (ii) THIS WAIVER HAS BEEN REVIEWED BY BORROWER AND BORROWER'S COUNSEL
AND IS A MATERIAL INDUCEMENT FOR AGENT AND LENDERS TO MAKE THE LOAN, ENTER INTO
THIS AGREEMENT AND EACH OF THE OTHER LOAN DOCUMENTS, AND (iii) THIS WAIVER SHALL
BE EFFECTIVE AS TO EACH OF SUCH OTHER LOAN DOCUMENTS AS IF FULLY INCORPORATED
THEREIN.

     14.12 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 the Borrower
shall not have the right to assign its rights or obligations under the Loan
Documents. Any assignee or transferee of the Notes 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 the Notes, shall be conclusive
and binding on any subsequent holder, transferee or assignee of such Notes or of
any note or notes issued in exchange therefor.

     14.13 ENTIRE AGREEMENT; MODIFICATION OF AGREEMENT. The Loan Documents,
together with certain letters from Agent and the Arranger to Borrower, accepted
by Borrower, embody the entire agreement among the Borrower, the Agent, and
Lenders and supersede all prior conversations, agreements, understandings,
commitments and term sheets among any or all of such parties with respect to the
subject matter hereof. Any provisions of this Agreement and the Guaranties and
any other Loan Documents may be amended or waived, or any liability thereunder
released, if, but only if, such amendment or waiver is in writing and is signed
by the Borrower, and Agent if the rights or duties of Agent in its capacity as
Agent are affected thereby, and

          (a) each of the Lenders, if such amendment or waiver

                                       70
<PAGE>


               (i) reduces or forgives any payment of principal or interest on
          the Obligations or any fees payable by Borrower to such Lender
          hereunder; or

               (ii) postpones the date fixed for any payment of principal of or
          interest on the Obligations or any fees payable by Borrower to such
          Lender hereunder; or

               (iii) changes the amount of such Lender's Commitment (other than
          pursuant to an assignment permitted under SECTION 13.3) or the unpaid
          principal amount of such Lender's Note; or

               (iv) extends the Maturity Date; or

               (v) Modifies Sections 7.2 (Maximum Consolidated Leverage Ratio)
          or 7.5 (Maximum Unencumbered Asset Coverage Ratio) or the definitions
          referenced therein; or

               (vi) changes the definition of Required Lenders or modifies any
          requirement for consent by each of the Lenders under this SECTION
          14.13(a); or

               (vii) releases any Guarantor from the obligations of any
          Guaranty; or

               (viii) increases the Aggregate Commitment above $200,000,000.

          (b) the Required Lenders, as to all such material amendments or
material waivers not otherwise listed in SECTION 14.13(a) above.

          (c) the Agent, as to all other matters of an administrative nature.

     Any amendment hereto pursuant to SECTION 2.19 hereof increasing the
Aggregate Commitment shall only require the consent of the Borrower, the Agent
and the Lender providing such new or increased Commitment.

     14.14 DEALINGS WITH THE BORROWER. The Lenders and their affiliates may
accept deposits from, extend credit to and generally engage in any kind of
banking, trust or other business with any of the Borrower or the Guarantors or
any of their Affiliates regardless of the capacity of the Lenders hereunder.

     14.15 SET-OFF.

          (a) If an Event of Default shall have occurred, each Lender shall have
the right, at any time and from time to time without notice to the Borrower, any
such notice being hereby expressly waived, to set-off and to appropriate or
apply any and all deposits of money or property or any other indebtedness at any
time held or owing by such Lender to or for the credit or the account of the
Borrower against and on account of all outstanding Obligations and all
Obligations which from time to time may become due hereunder and all other
obligations and liabilities of the Borrower under this Agreement, irrespective
of whether or not such Lender shall have made any demand hereunder and whether
or not said obligations and liabilities shall have matured.



                                       71
<PAGE>

          (b) Each Lender agrees that if it shall, by exercising any right of
set-off or counterclaim or otherwise, receive payment of a proportion of the
aggregate amount of principal, interest or fees due with respect to any Note
held by it which is greater than the proportion received by any other Lender in
respect of the aggregate amount of principal, interest or fees due with respect
to any Note held by such other Lender, the Lender receiving such proportionately
greater payment shall purchase such participations in the Notes held by the
other Lenders and such other adjustments shall be made as may be required so
that all such payments of principal, interest or Fees with respect to the Notes
held by the Lenders shall be shared by the Lenders pro rata according to their
respective Commitments.

     14.16 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one agreement, and
any of the parties hereto may execute this Agreement by signing any such
counterpart. This Agreement shall be effective when it has been executed by the
Borrower and each of the Lenders shown on the signature pages hereof.

     14.17 DISCRETION. In exercising any discretion reserved herein to the
Agent, the Required Lenders or the Lenders, the Agent, the Required Lenders or
the Lenders, as the case may be, shall exercise such discretion in a manner
which is commercially reasonable by the standards of the commercial lending
industry with respect to credits comparable to the Facility.

                                   ARTICLE XV

                                    EXHIBIT A

                                FORM OF GUARANTY

     This Guaranty made as of ___________________, by
_____________________________ ("Guarantor"), to and for the benefit of Bank One,
NA, individually as a lender ("Bank One") and as agent ("Agent") for itself and
the other Lenders, as defined in the Credit Agreement (as defined below), and
their respective successors and assigns.

                                    RECITALS

     A. Great Lakes REIT, L.P. a Delaware limited partnership ("Borrower") has
requested that the Lenders make an unsecured revolving credit facility available
to Borrower in the aggregate principal amount of up to $200,000,000
("Facility"), and that Agent act as administrative agent with respect thereto.

     B. The Lenders have agreed to make available the Facility to Borrower, and
Agent has agreed to act in said agency capacity, pursuant to the terms and
conditions set forth in an Unsecured Revolving Credit Agreement dated March 23,
2001, between Borrower, Agent and the Lenders ("Credit Agreement"), and
Guarantor desires that the Lenders continue to make Advances under the Credit
Agreement and that Agent continue to act in said agency capacity. All
capitalized terms used and not otherwise defined herein shall have the
respective meanings ascribed to such terms in the Credit Agreement.

     C. Borrower has executed and delivered to the Lenders one or more
promissory notes each dated March 23, 2001 as evidence of its indebtedness to
the Lenders with respect to the Facility (the promissory notes described above,
together with any amendments or allonges thereto, or restatements, replacements
or renewals thereof, and/or new promissory notes to new Lenders under the Credit
Agreement, are collectively referred to herein as the "Notes").

     D. Guarantor is deriving and will continue to derive substantial financial
benefit from the Facility evidenced by the Notes, the Credit Agreement and the
other Loan Documents.

     E. The execution and delivery of this Guaranty by Guarantor is required
pursuant to the express terms of the Credit Agreement as a condition to any
further Advances under the Facility.

                                   AGREEMENTS

     NOW, THEREFORE, in consideration of the matters described in the foregoing
Recitals, which Recitals are incorporated herein and made a part hereof, and for
other good and valuable consideration, Guarantor hereby agrees as follows:

     1. Guarantor hereby jointly and severally, absolutely, unconditionally, and
irrevocably guarantees to Agent and the Lenders:

          (a) the full and prompt payment of the principal of and interest on
the Notes when due, whether at stated maturity, upon acceleration or otherwise,
and at all times thereafter,




<PAGE>

and the prompt payment of all other sums which may now be or may hereafter
become due and owing under the Notes, the Credit Agreement and/or the other Loan
Documents;

          (b) the payment of all Enforcement Costs (as hereinafter defined); and

          (c) the full, complete, and punctual observance, performance, and
satisfaction of all of the obligations, duties, covenants, and agreements of
Borrower under the Credit Agreement and the Loan Documents.

     All amounts due, debts, liabilities, and payment obligations described in
subparagraphs (a) and (b) of this Paragraph 1 are referred to herein as the
"Facility Indebtedness. " All obligations described in subparagraph (c) of this
Paragraph 1 are referred to herein as the "Obligations."

     2. In the event of any default by Borrower in making payment of the
Facility Indebtedness, or in performance of the Obligations, Guarantor agrees,
on demand by Agent, to pay all the Facility Indebtedness and to perform all the
Obligations as are or then or thereafter become due and owing or are to be
performed under the terms of the Notes, the Credit Agreement and/or the other
Loan Documents, and to pay any reasonable expenses incurred by Agent or the
Lenders in protecting, preserving or defending its interest in any collateral
for the Facility, or otherwise in connection with the Facility or under any of
the Loan Documents, including, without limitation, all reasonable attorneys'
fees and costs. Agent shall have the right, at its option, either before, during
or after pursuing any other right or remedy against Borrower or Guarantor, to
perform any and all of the Obligations by or through any agent, contractor or
subcontractor, or any of their agents, of its selection, all as Agent in its
sole discretion deems proper, and Guarantor shall indemnify and hold Agent and
the Lenders free and harmless from and against any and all loss, damage, cost,
expense, injury, or liability Agent or the Lenders may suffer or incur in
connection with the exercise of its rights under this Guaranty or the
performance of the Obligations, except to the extent the same arises as a result
of the gross negligence or willful misconduct of Agent.

     All of the remedies set forth herein and/or provided by any of the Loan
Documents or law or equity shall be equally available to Agent for the benefit
of itself and the Lenders, and the choice by Agent of one such alternative over
another shall not be subject to question or challenge by Guarantor or any other
person, nor shall any such choice be asserted as a defense, set-off or failure
to mitigate damages in any action, proceeding or counteraction by Agent for the
benefit of itself and/or the Lenders to recover or seeking any other remedy
under this Guaranty, nor shall such choice preclude Agent from subsequently
electing to exercise a different remedy. The parties have agreed to the
alternative remedies hereinabove specified in part because they recognize that
the choice of remedies in the event of a failure hereunder will necessarily and
should properly be a matter of business judgment, which, with hindsight after
the passage of time and events, may or may not prove to have been the best
choice to maximize recovery by Agent for the benefit of itself and the Lenders
at the lowest cost to Borrower and/or Guarantor. It is the intention of the
parties that such choice by Agent be given conclusive effect regardless of such
subsequent developments.

     3. Guarantor does hereby waive (i) notice of acceptance of this Guaranty by
Agent or the Lenders and any and all notices and demands of every kind which may
be required to be given by any statute, rule or law, (ii) any defense, right of
set-off or other claim which Guarantor



                                       82
<PAGE>

may have against the Borrower or which Guarantor or Borrower may have against
Agent or any of the Lenders or any holder of any Note, (iii) presentment for
payment, demand for payment, notice of nonpayment, dishonor, protest and notice
of protest, diligence in collection and any and all formalities which otherwise
might be legally required to charge Guarantor with liability, (iv) any failure
by Agent or any of the Lenders to inform Guarantor of any facts Agent or any of
the Lenders may now or hereafter know about Borrower, the Facility, or the
transactions contemplated by the Credit Agreement, it being understood and
agreed that Agent and the Lenders have no duty so to inform and that Guarantor
is fully responsible for being and remaining informed by Borrower of all
circumstances bearing on the existence or creation or risk of nonpayment of the
Facility Indebtedness or the risk of nonperformance of the Obligations, and (v)
any and all right to cause a marshaling of assets of the Borrower or any other
action by any court or governmental body with respect thereto, or to cause Agent
or any of the Lenders to proceed against any other security given to Agent or
any of the Lenders in connection with the Facility Indebtedness or the
Obligations. Credit may be granted or continued from time to time by Lenders to
Borrower without notice to or authorization from Guarantor, regardless of the
financial or other condition of Borrower at the time of any such grant or
continuation. Guarantor acknowledges that no representations of any kind
whatsoever have been made by Agent or any of the Lenders to Guarantor. No
modification or waiver of any of the provisions of this Guaranty shall be
binding upon Agent or the Lenders except as expressly set forth in a writing
duly signed and delivered on behalf of Agent and the Lenders.

     4. Guarantor further agrees that Guarantor's liability as guarantor shall
in nowise be impaired by any renewals or extensions which may be made from time
to time, with or without the knowledge or consent of Guarantor of the time for
payment of interest or principal under the Notes or by any forbearance or delay
in collecting interest or principal under the Notes, or by any waiver under the
Credit Agreement or any other Loan Documents, or by failure or election not to
pursue any other remedies against Borrower, or by any change or modification in
the Notes, the Credit Agreement or any other Loan Documents, or by the
acceptance of any additional security or any increase, substitution or change
therein, or by the release of any security or any withdrawal thereof or decrease
therein, or by the application of payments received from any source to the
payment of any obligation other than the Facility Indebtedness, even though
Agent or the Lenders might lawfully have elected to apply such payments to any
part or all of the Facility Indebtedness, it being the intent hereof that
Guarantor shall remain liable as principal for payment of the Facility
Indebtedness and performance of the Obligations until all indebtedness has been
paid in full and the other terms, covenants and conditions of the Credit
Agreement and other Loan Documents and this Guaranty have been performed,
notwithstanding any act or thing which might otherwise operate as a legal or
equitable discharge of a surety. Guarantor further understands and agrees that
Agent and the Lenders may at any time enter into agreements with Borrower to
amend and modify the Notes, Credit Agreement or other Loan Documents, and may
waive or release any provision or provisions thereof, and, with reference to
such instruments, may make and enter into any such agreement or agreements as
Agent, the Lenders and Borrower may deem proper and desirable, without in any
manner impairing this Guaranty or any of Agent's or the Lenders' rights
hereunder or any of the Guarantor's obligations hereunder.

     5. This is an absolute, unconditional, complete, present and continuing
guaranty of payment and performance, and not of collection only. Guarantor
agrees that this Guaranty may be enforced by Agent and the Lenders without the
necessity at any time of resorting to or exhausting any other security or
collateral given in connection herewith or with the Facility or



                                       83
<PAGE>

any of the Loan Documents, or resorting to any other guaranties, and Guarantor
hereby waives the right to require Agent or the Lenders to join Borrower in any
action brought hereunder or to commence any action against or obtain any
judgment against Borrower or to pursue any other remedy or enforce any other
right. Guarantor further agrees that nothing contained herein or otherwise shall
prevent Agent and the Lenders from pursuing concurrently or successively all
rights and remedies available to it at law and/or in equity or under any of the
Loan Documents, and the exercise of any of its rights or the completion of any
of its remedies shall not constitute a discharge of any of Guarantor's
obligations hereunder, it being the purpose and intent of Guarantor that the
obligations of Guarantor hereunder shall be primary, absolute, independent and
unconditional under any and all circumstances whatsoever. Neither Guarantor's
obligations under this Guaranty nor any remedy for the enforcement thereof shall
be impaired, modified, changed or released in any manner whatsoever by any
impairment, modification, change, release or limitation of the liability of
Borrower under the Notes, the Credit Agreement or any other Loan Documents or by
reason of Borrower's bankruptcy or by reason of any creditor or bankruptcy
proceeding instituted by or against Borrower. This Guaranty shall continue to be
effective and be deemed to have continued in existence or be reinstated (as the
case may be) if at any time payment of all or any part of any sum payable
pursuant to the Notes, the Credit Agreement or any other Loan Document is
rescinded or otherwise required to be returned by the payee upon the insolvency,
bankruptcy, or reorganization of the payer, all as though such payment had not
been made, regardless of whether Agent or any of the Lenders contested the order
requiring the return of such payment. The obligations of Guarantor pursuant to
the preceding sentence shall survive any termination, cancellation or release of
this Guaranty.

     6. This Guaranty shall be assignable by Agents and/or any of the Lenders to
any assignee of all or a portion of Agents and/or such Lender's rights under the
Loan Documents.

     7. If: (i) this Guaranty, any Note, the Credit Agreement or any other Loan
Document is placed in the hands of an attorney for collection or is collected
through any legal proceeding; (ii) an attorney is retained to represent Agent
and/or any of the Lenders in any bankruptcy, reorganization, receivership, or
other proceedings affecting creditors' rights and involving a claim under this
Guaranty, any Note, the Credit Agreement or any Loan Document; (iii) an attorney
is retained to provide advice or other representation with respect to the Loan
Documents in connection with an enforcement action or potential enforcement
action; or (iv) an attorney is retained to represent Agent and/or any of the
Lenders in any other legal proceedings whatsoever in connection with this
Guaranty, any Note, the Credit Agreement, any of the other Loan Documents or any
property subject thereto, then Guarantor shall pay upon demand all reasonable
attorney's fees, costs and expenses for the Agent and each of the other Lenders,
including, without limitation, court costs, filing fees, recording costs and all
other costs and expenses whatsoever incurred in connection therewith (all of
which are referred to herein as "Enforcement Costs"), in addition to all other
amounts due hereunder; provided, however, that the expenses of counsel for which
Borrower is obligated under this subsection (b) shall be limited to the
reasonable non-duplicative expenses of (A) a single outside law firm
representing Agent, and (B) a single outside law firm representing all of the
other Lenders as a group (which may or may not be the same law firm representing
Agent).

     8. The parties hereto intend that each provision in this Guaranty comports
with all applicable local, state and federal laws and judicial decisions.
However, if any provision or provisions, or if any portion of any provision or
provisions, in this Guaranty is found by a court



                                       84
<PAGE>

of competent jurisdiction to be in violation of any applicable local, state or
federal ordinance, statute, law, administrative or judicial decision, or public
policy, and if such court should declare such portion, provision or provisions
of this Guaranty to be illegal, invalid, unlawful, void or unenforceable as
written, then it is the intent of all parties hereto that such portion,
provision or provisions shall be given force to the fullest possible extent that
they are legal, valid and enforceable, that the remainder of this Guaranty shall
be construed as if such illegal, invalid, unlawful, void or unenforceable
portion, provision or provisions were not contained therein, and that the
rights, obligations and interest of Agent, the Lenders and the holder(s) of the
Notes under the remainder of this Guaranty shall continue in full force and
effect.

     9. Any indebtedness of Borrower to Guarantor now or hereafter existing is
hereby subordinated to the Facility Indebtedness. Guarantor agrees that until
the entire Facility Indebtedness has been paid in full, (i) Guarantor will not
seek, accept or retain for Guarantor's own account, any payment from Borrower on
account of such subordinated debt, and (ii) any such payments to Guarantor on
account of such subordinated debt shall be collected and received by Guarantor
in trust for Agent and the Lenders and shall be paid over to Agent on account of
the Facility Indebtedness without impairing or releasing the obligations of
Guarantor hereunder.

     10. Guarantor waives and releases any claim (within the meaning of 11
U.S.C. Section 101) which Guarantor may have against Borrower arising from a
payment made by Guarantor under this Guaranty and agrees not to assert or take
advantage of any subrogation rights of Guarantor, Agent or the Lenders or any
right of Guarantor, Agent or the Lenders to proceed against (i) Borrower for
reimbursement, or (ii) any other guarantor or any collateral security or
guaranty or right of offset held by Agent or the Lenders for the payment of the
Facility Indebtedness and performance of the Obligations, nor shall Guarantor
seek or be entitled to seek any contribution or reimbursement from Borrower or
any other guarantor in respect of payments made by Guarantor hereunder. It is
expressly understood that the waivers and agreements of Guarantor set forth
above constitute additional and cumulative benefits given to Agent and the
Lenders for their security and as an inducement for their continuing extension
of credit to Borrower.

     11. Any amounts received by Agent or Lender from any source on account of
any indebtedness may be applied by Agent toward the payment of such
indebtedness, and in such order of application, as Agent may from time to time
elect.

     12. This Guaranty shall be governed by the internal laws of the State of
Illinois, without regard to its choice of law rules or conflict of laws
principles. The Guarantor hereby submits to personal jurisdiction in the State
of Illinois for the enforcement of this Guaranty and waives any and all personal
rights to object to such jurisdiction for the purposes of litigation to enforce
this Guaranty. Guarantor hereby consents to the jurisdiction of either the
Circuit Court of Cook County, Illinois, or the United States District Count for
the Northern District of Illinois, in any action, suit, or proceeding which
Agent or the Lenders may at any time wish to file in connection with this
Guaranty or any related matter. Guarantor hereby agrees that an action, suit, or
proceeding to enforce this Guaranty may be brought in any state or federal court
in the State of Illinois and hereby waives any objection which Guarantor may
have to the laying of the venue of any such action, suit, or proceeding in any
such court; provided, however, that the provisions of this Paragraph shall not
be deemed to preclude Agent or the Lenders from filing any such action, suit, or
proceeding in any other appropriate forum.

     [14. Guarantors and Lender agree that such Guarantor's obligations
hereunder shall not exceed the maximum amount not subject to avoidance under
Title 11 of the United State Code, as same may be amended from time to time, or
any applicable state law (the "Bankruptcy Code"). To that end, to the extent
such obligations would otherwise be subject to avoidance under the Bankruptcy
Code if such Guarantor is not deemed to have received valuable consideration,
fair value or reasonably equivalent value for its obligations hereunder, any
such Guarantor's obligations hereunder shall be reduced to that amount which,
after giving effect



                                       86
<PAGE>

thereto, would not render such Guarantor insolvent, or leave such Guarantor with
an unreasonably small capital to conduct its business, or cause the Guarantor to
have incurred debts (or intended to have incurred debts) beyond its ability to
pay such debts as they mature, as such terms are determined, and at the time
such obligations are deemed to have been incurred, under the Bankruptcy Code. In
the event any Guarantor shall make any payment or payments under this Guaranty,
each other Guarantor shall contribute to such paying Guarantor an amount equal
to such non-paying Guarantor's pro rata share (based on their respective maximum
liabilities hereunder) of such payment or payments made by such paying
Guarantor, provided that such contribution right shall be subordinate and junior
in right of payment to all the Facility Indebtedness and performance of all of
the Obligations to Lender.][SECTION 14 TO BE INCLUDED ONLY IN GUARANTEES OF
SUBSIDIARY GUARANTORS.]

     15. All obligations under this Guaranty are joint and several to the
Guarantor and any other party which now or hereafter guaranties the payment of
any portion of the Facility Indebtedness or the performance of the Obligations.
This Guaranty shall be binding upon the heirs, executors, legal and personal
representatives, successors and assigns of Guarantor and shall inure to the
benefit of Agent's and Lender's successors and assigns.

     16. This Guaranty shall be construed and enforced under the internal laws
of the State of Illinois.

     17. EACH GUARANTOR HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE
ANY RIGHT THAT IT MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION ARISING IN ANY
WAY IN CONNECTION WITH THIS GUARANTY, OR ANY OF THE OTHER LOAN DOCUMENTS, THE
LOAN, OR ANY OTHER STATEMENTS OR ACTIONS OF ANY PARTY HERETO. EACH GUARANTOR

                          FORM OF ASSIGNMENT AGREEMENT

     This Assignment Agreement (this "Assignment Agreement") between
_____________________ (the "Assignor") and ________________________(the
"Assignee") is dated as of ________________, 200_. The parties hereto agree as
follows:

     1. PRELIMINARY STATEMENT. The Assignor is a party to the Unsecured
Revolving Credit Agreement (which, as it may have been amended, modified,
renewed or extended through the Effective Date is herein called the "Credit
Agreement") described in Item 1 of Schedule 1 attached hereto ("Schedule 1").
Capitalized terms used herein and not otherwise defined herein shall have the
meanings attributed to them in the Credit Agreement.

     2. ASSIGNMENT AND ASSUMPTION. The Assignor hereby sells and assigns to the
Assignee without recourse, and the Assignee hereby purchases and assumes from
the Assignor, an interest in and to the Assignor's rights and obligations under
the Credit Agreement such that after giving effect to such assignment the
Assignee shall have purchased pursuant to this Assignment Agreement the
percentage interest specified in Item 3 of Schedule 1 of all outstanding rights
and obligations under the Credit Agreement and the other Loan Documents. The
aggregate Commitment (or Loans, if the applicable Commitment has been
terminated) purchased by the Assignee hereunder is set forth in Item 4 of
Schedule 1.

     3. EFFECTIVE DATE. The effective date of this Assignment Agreement (the
"Effective Date") shall be the later of the date specified in Item 6 of Schedule
1 or two (2) Business Days (or such shorter period agreed to by the Agent) after
a Notice of Assignment substantially in the form of Exhibit "I" attached hereto
has been delivered to the Agent. In no event will the Effective Date occur if
the payments required to be made by the Assignee to the Assignor on the
Effective Date under SECTIONS 4 AND 5 hereof are not made on the proposed
Effective Date, unless otherwise agreed to in writing by Assignor and Assignee.
The Assignor will notify the Assignee of the proposed Effective Date no later
than the Business Day prior to the proposed Effective Date. As of the Effective
Date, (i) the Assignee shall have the rights and obligations of a Lender under
the Loan Documents with respect to the rights and obligations assigned to the
Assignee hereunder and (ii) the Assignor shall relinquish its rights and be
released from its corresponding obligations under the Loan Documents with
respect to the rights and obligations assigned to the Assignee hereunder.

     4. PAYMENTS OBLIGATIONS. On and after the Effective Date, the Assignee
shall be entitled to receive from the Agent all payments of principal, interest
and fees with respect to the interest assigned hereby. The Assignee shall
advance funds directly to the Agent with respect to all Loans and reimbursement
payments made on or after the Effective Date with respect to the interest
assigned hereby. [In consideration for the sale and assignment of Loans
hereunder, (i) the Assignee shall pay the Assignor, on the Effective Date, an
amount equal to the principal amount of the portion of all Alternate Base Rate
Loans assigned to the Assignee hereunder and (ii) with respect to each ratable
LIBOR Advance made by the Assignor and assigned to the Assignee hereunder which
is outstanding on the Effective Date, (a) on the last day of the LIBOR Interest
Period therefor or (b) on such earlier date agreed to by the Assignor and the
Assignee or (c) on the date on which any such Loan either becomes due (by
acceleration or otherwise) or is prepaid (the date as described in the foregoing
clauses (a), (b) or (c) being





<PAGE>

hereinafter referred to as the "Fixed Due Date"), the Assignee shall pay the
Assignor an amount equal to the principal amount of the portion of such Loan
assigned to the Assignee which is outstanding on the Fixed Due Date. If the
Assignor and the Assignee agree that the applicable Fixed Due Date for such Loan
shall be the Effective Date, they shall agree, solely for purposes of dividing
interest paid by the Borrower on such Loan, to an alternate interest rate
applicable to the portion of such Loan assigned hereunder for the period from
the Effective Date to the end of the related LIBOR Interest Period (the "Agreed
Interest Rate") and any interest received by the Assignee in excess of the
Agreed Interest Rate, with respect to such Loan for such period, shall be
remitted to the Assignor. In the event a prepayment of any Loan which is
existing on the Effective Date and assigned by the Assignor to the Assignee
hereunder occurs after the Effective Date but before the applicable Fixed Due
Date, the Assignee shall remit to the Assignor any excess of the funding
indemnification amount paid by the Borrower under SECTION 4.4 of the Credit
Agreement an account of such prepayment with respect to the portion of such Loan
assigned to the Assignee hereunder over the amount which would have been paid if
such prepayment amount were calculated based on the Agreed Interest Rate and
only covered the portion of the Interest Period after the Effective Date. The
Assignee will promptly remit to the Assignor (i) the portion of any principal
payments assigned hereunder and received from the Agent with respect to any such
Loan prior to its Fixed Due Date and (ii) any amounts of interest on Loans and
fees received from the Agent which relate to the portion of the Loans assigned
to the Assignee hereunder for periods prior to the Effective Date, in the case
of ratable Alternate Base Rate Loans or Fees, or the Fixed Due Date, in the case
of LIBOR Loans, and not previously paid by the Assignee to the Assignor.]* In
the event that either party hereto receives any payment to which the other party
hereto is entitled under this Assignment Agreement, then the party receiving
such amount shall promptly remit it to the other party hereto.

     5. FEES PAYABLE BY THE ASSIGNEE. The Assignee shall pay to the Assignor a
fee on each day on which a payment of interest or Facility Fees is made under
the Credit Agreement with respect to the amounts assigned to the Assignee
hereunder (other than a payment of interest or Facility Fees attributable to the
period prior to the Effective Date or, in the case of LIBOR Loans, the Fixed Due
Date, which the Assignee is obligated to deliver to the Assignor pursuant to
SECTION 4 hereof). The amount of such fee shall be the difference between (i)
the interest or fee, as applicable, paid with respect to the amounts assigned to
the Assignee hereunder and (ii) the interest or fee, as applicable, which would
have been paid with respect to the amounts assigned to the Assignee hereunder if
each interest rate was calculated at the rate of ___% rather than the actual
percentage used to calculate the interest rate paid by the Borrower or if the
Facility Fee was calculated at the rate of % rather than the actual percentage
used to calculate the Facility Fee paid by the Borrower, as applicable. In
addition, the Assignee agrees to pay ___% of the fee required to be paid to the
Agent in connection with this Assignment Agreement. [THIS SENTENCE CAN BE
REVISED APPROPRIATELY BASED ON HOW THE FEE IS BEING PAID.]

                          OPINION OF BORROWER'S COUNSEL

March 23, 2001


The Agent and the Lenders who are parties to
the Credit Agreement described below


Gentlemen/Ladies:

         We are acting as special counsel to Great Lakes REIT, L.P., a Delaware
limited partnership (the "Borrower"), Great Lakes REIT, Inc., a Maryland real
estate investment trust (the "General Partner"), GLR No. 1, Inc., an Illinois
corporation, GLR No. 2, Inc., an Illinois corporation, and GLR No. 3, a Maryland
real estate investment trust and GLR-1600 Corporate Center, LLC, a Delaware
limited liability company, (collectively, the "Consolidated Group"), and have
represented the Consolidated Group in connection with the execution and delivery
of an Unsecured Revolving Credit Agreement dated as of March 23, 2001 (the
"Agreement") among the Borrower, Bank One, NA, and certain other banks, as
lenders, and Bank One, NA, as agent, providing for loans in an aggregate
principal amount from time to time not exceeding $200,000,000 at any one time
outstanding, and certain other agreements executed in connection therewith. 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 certificate of limited partnership,
limited partnership agreement and resolutions of the General Partner, articles
of incorporation, declaration of trust, limited partnership agreement or
by-laws, as the case may be, and resolutions of each Guarantor, the Agreement,
the Notes, the Guaranties, the Officer's Certificate of the Borrower attached
hereto as Exhibit A (the "Officer's Certificate") and such other certificates of
the Borrower and the Guarantors and public officials and matters of fact and law
as we deem necessary or appropriate to render this opinion.

         Based on the foregoing, and subject to the limitations, qualifications
and assumptions set forth herein, we are of the opinion that:

         1.       The Borrower is a duly formed limited partnership, and each of
the Guarantors is duly formed as a corporation or real estate investment trust,
as the case may be; and the Borrower and the Guarantors are validly existing and
in good standing under the laws of their states of incorporation or formation,
and they each have all requisite authority and power to enter into, and perform
their respective obligations under, the Loan Documents. The Borrower is
qualified to conduct business in the States of Colorado, Illinois, Michigan,
Minnesota and Ohio. The General Partner is qualified to do business in the
States of Michigan and Ohio.

         2.       The execution and delivery of the Agreement and the Notes by
the Borrower and the performance by the Borrower of its obligations under the
Agreement and the Notes have

<PAGE>

been duly authorized by all necessary corporate action and/or proceedings on the
part of the Borrower and will not:

                  (a)      violate (i) any law, rule or regulation of the State
         of Illinois or of the United States of America or (ii) the Borrower's
         limited partnership certificate or limited partnership agreement or the
         General Partner's declaration of trust or by-laws or (iii) any order,
         writ, decree or judgment binding upon the Borrower or the General
         Partner or their respective properties or assets; or

                  (b)      result in a breach of or constitute a default under,
         or give to others any rights of termination, amendment, acceleration or
         cancellation of, or result in the creation of a lien, charge or other
         encumbrance on any property or asset of the Borrower or the General
         Partner pursuant to, any indenture, note, mortgage, deed of trust,
         security or pledge agreement, guarantee or loan or other agreement to
         which the Borrower or the General Partner is a party or by which it or
         any of its respective properties or assets is bound.

         The opinion set forth in clauses (a)(iii) and (b) above is limited to
orders, writs, decrees and judgments and indentures, notes, mortgages, deeds of
trust, security or pledge agreements, guarantees or loan or other agreements
that have been identified to us in the Officer's Certificate, and we express no
opinion in clauses (a)(iii) and (b) with respect to any violation of any order,
writ, decree or judgment or indenture, mortgage, deed of trust, security or
pledge agreement, guarantee or loan or other agreement not so identified to us
or arising under or based upon any covenant of a financial or numerical nature
or requiring computation. We have no reason to believe that the information
certified in the Officer's Certificate is not correct.

         3.       The execution and delivery of the Guaranties by each Guarantor
and the performance by each Guarantor of its obligations under the Guaranties
have been duly authorized by all necessary corporate action and/or proceedings
on the part of each Guarantor and will not:

                  (a)      violate (i) any law, rule or regulation of the State
         of Illinois or of the United States of America or (ii) such Guarantor's
         articles of incorporation or declaration of trust, as the case may be,
         or by-laws or (iii) any order, writ, decree or judgment binding upon
         the Guarantor or its respective properties or assets; or

                  (b)      result in a breach of or constitute a default under,
         or give to others any rights of termination, amendment, acceleration or
         cancellation of, or result in the creation of a lien, charge or other
         encumbrance on any property or asset of such Guarantor pursuant to, any
         indenture, note, mortgage, deed of trust, security or pledge agreement,
         guarantee or loan or other agreement to which such Guarantor is a party
         or by which it or any of its respective properties or assets is bound.

         The opinion set forth in clauses (a)(iii) and (b) above is limited to
orders, writs, decrees and judgments and indentures, notes, mortgages, deeds of
trust, security or pledge agreements, guarantees or loan or other agreements
that have been identified to us in the Officer's Certificate, and we express no
opinion in clauses (a)(iii) and (b) with respect to any violation of any order,
writ, decree or judgment or indenture, mortgage, deed of trust, security or
pledge agreement, guarantee or loan or other agreement not so identified to us
or arising under or based upon any

                                      102
<PAGE>

covenant of a financial or numerical nature or requiring computation. We have no
reason to believe that the information certified in the Officer's Certificate is
not correct.

         4.       The Agreement and the Notes have been duly executed and
delivered by the Borrower and constitute legal, valid and binding obligations of
the Borrower enforceable in accordance with their respective terms, subject to
bankruptcy, reorganization, insolvency, fraudulent conveyance and similar laws
affecting creditors' rights generally, and general principles of equity
(regardless of whether the application of such principles is considered in a
proceeding in equity or at law).

         5.       The Guaranties have been duly executed and delivered by each
Guarantor and constitutes legal, valid and binding obligation of such Guarantor
enforceable in accordance with their respective terms, subject to bankruptcy,
reorganization, insolvency, fraudulent conveyance and similar laws affecting
creditors' rights generally, and general principles of equity (regardless of
whether the application of such principles is considered in a proceeding in
equity or at law).

         6.       No approval, authorization, consent or order of, or
registration or filing with, any governmental authority which has not been made
or obtained is required to be obtained or made by the Borrower or any Guarantor
in connection with the execution and delivery of the Notes, the Agreement or the
Guaranties.

         7. The payment by the Borrower of all amounts required to be paid with
respect to the Notes in accordance with the terms of the Agreement will not
violate the provisions of any Illinois or federal law limiting or regulating the
payment of interest on obligations.

         In rendering the foregoing opinion, we have assumed, but not
independently verified, (a) the genuineness of the signatures and the authority
of all persons signing documents in connection with the matters addressed by
this opinion on behalf of parties other than the Borrower and the Guarantors,
(b) the authenticity of all documents submitted to us as originals and (c) the
conformity to authentic original documents of all documents submitted to us as
certified, conformed or photostatic copies.

         We express no opinion as to (i) the enforceability of the Agreement,
the Notes or the Guaranty in the event the Lenders fail to act in good faith and
in a commercially reasonable manner or (ii) the enforceability of any provision
which purports to restrict access to courts or to legal or equitable remedies or
which relates to submission to jurisdiction or venue of courts, waives any
rights to notices, waives any remedies, defenses, trial by jury or other
benefits bestowed by operation of law or (iii) the due authorization of
borrowings by the Borrower or of guaranties by the Guarantors under the Loan
Documents in excess of $150,000,000.

         We are admitted to the Bar of the State of Illinois and, except as set
forth below, we express no opinion regarding the laws of any other jurisdiction
other than the federal law of the United States of America. Insofar as our
opinion in paragraph 1 relates to matters of Maryland law, our opinion is given
in reliance upon an examination of Title 8 of the Maryland Corporations and
Associations Code Annotated (1995).

         This opinion is delivered to you for your own use and benefit in
connection with the transactions contemplated by the Agreement and is not to be
relied upon by any other person (other than Participants and the Lenders'
permitted assignees) or for any other purpose. We

                                      103
<PAGE>

assume no obligation to supplement this opinion if any applicable laws change
after the date hereof or if we become aware of any facts that might change the
opinions expressed herein after the date hereof.

                                    Very truly yours,

                                    EXHIBIT G

                 SCOPE OF WORK FOR ENVIRONMENTAL INVESTIGATIONS

ENVIRONMENTAL SITE ASSESSMENTS

BANK ONE, NA REPORTING STANDARDS

The following are Guidelines for the qualification of firms and for information
to be included in Environmental Site Assessments. These standards include the
minimum elements common to acceptable site assessments. Generally, it is
intended for the standards to be consistent with those outlined in the American
Society for Testing and Materials (ASTM) Designation: E 1527-00. This listing is
not intended to be a "how to" manual, as we rely on the environmental
professionals to expand the scope of their services and the information included
in the reports as required.

QUALIFICATIONS OF INVESTIGATING FIRM

The firm must have 5 years of experience in hazardous substances investigation.
Many of these firms began as geotechnical consultants, but expertise only in
soils analysis does not qualify them for hazardous substance analysis. The
person supervising and signing the report should be experienced in all matters
covered in the report. He should be a registered professional engineer or have
advanced degrees in related disciplines. The firm performing the work should be
of a professional nature WITH KNOWLEDGE OF LOCAL CONDITIONS.

DEPTH OF REPORTING REQUIRED

Phase I - Consists of site description, review of historical and
regulatory data and a physical inspection. If no potential contamination is
indicated, the report should so state, and a specific statement should be made
that no further investigation is required (see content requirements below).

Phase II - If a Phase I examination indicates the possibility of contamination,
the consultant should describe his suspicions, the areas to be tested, sampling
procedures to be used and methods used to assess the sample. He should then
specify and carry out a testing program for further evaluation.

Phase III - If Phase II reveals contamination at the site, the consultant will
design and implement a remediation program to remove the identified hazardous
materials. The report should include an estimated cost for the clean-up.

The initial Phase I site assessment report should include the following:

SITE DESCRIPTION

The site description section should include a detailed description of the site,
existing buildings and current site use. It should also include a general
description of the uses and conditions of adjacent properties which might result
in migrating contamination. It should include a summary of the visual
observations including, but not limited to, vegetation stress, debris, fill
materials,

<PAGE>

ponding, evidence of underground storage tanks, evidence of previous
dumping or storage, discolored or stained soils, wetlands, groundwater flows,
and a description of regional geology and hydrology. On vacant sites, the
investigator should compare his observations to a USGS topographic map, noting
any changes in elevations or depressions which have been covered over, possibly
indicating past dumping or burial of wastes.

On sites with existing improvements the investigator should interview personnel
at the site regarding hazardous materials currently or previously used at the
site, underground storage tanks, pipeline right of ways and any other areas of
concern. Buildings should be checked for asbestos containing materials, PCB
equipment, etc.

HISTORICAL USES OF SITE, ADJACENT PROPERTIES, AND SIGNIFICANT NEARBY PROPERTY

The historical analysis should provide a chronology of past and present
significant uses of the subject site and adjacent sites, and highlight
activities which might have contributed unacceptable levels of contaminants. It
should contain an explanation of the methods of historical search which were
pursued, the information expected to be obtained and the information actually
obtained from each search. In general, the historical review should cover 30 -
40 years of history depending on the availability of information. Its purpose is
to investigate the possibility of prior hazardous substances releases at the
property, identify potential contingent liability from historic off-site
disposal of hazardous substances, or identify sources of contamination which
have or might in the future migrate to the site.

The historical analysis should include but not be limited to:

o        Review of aerial photographs to identify past land uses and development
         trends, and identify possible locations of ponds, landfills, tanks,
         areas of soil discoloration or drum storage.
o        Review county tax records or title search to identify past uses of
         potential concern such as gas stations or industrial uses.
o        Conversations with local environmental and health officials,
         investigation of local, state and federal regulatory agencies files
         including the EPA, DER and Corps of Engineers, and a check of EPA lists
         of known contaminated sites, to check for recorded hazardous substances
         handling, or potential permitting requirements of air emissions,
         wastewater, RCRA or TSD permits.

Other information which may be attached to the report include, but should not be
limited to:

o        A discussion of existing and proposed environmental standards and
         legislation of the area
o        Site Plan
o        Ground level photos of the site with specific attention to any
         characteristics noted in the report
o        Area diagram showing the location of any matters mentioned in the
         report and showing the site and adjacent properties if any potential
         hazardous sources are identified on adjacent or nearby properties
o        Copies of representative aerial photos
o        Copies of correspondence with regulatory agencies
o        Documents acquired during title search
o        Chain of custody records

                                      110
<PAGE>

o        Location map of site and immediate surroundings
o        Listing of adjacent property owners and use of the properties
o        Any other material available which describes or verifies information
         given or conclusions drawn in the report.

Conclusions and Recommendations

The Consultant will prepare a complete written report which fully define the
scope of his responsibilities and objectives. It should describe the sources
used, the activities performed, the dates when activities were performed, the
results of research and recommendations. Specific recommendations for remedial
action, additional tests or investigations for each recognized area of concern
or condition and approximate costs of further investigation or remediation shall
be provided within the report.

The conclusion section must clearly state that the firm has exercised
professional judgement in reaching one of the following:

The Consultant, after performing the appropriate level of investigation, has
revealed no evidence of recognized environmental conditions in connection with
the subject property and no further testing or investigation is warranted; or

The Consultant, after performing the appropriate level of investigation, has
revealed no evidence of recognized environmental conditions in connection with

                              ENVIRONMENTAL MATTERS

ARLINGTON RIDGE SERVICE CENTER, ARLINGTON HEIGHTS, ILLINOIS

A tenant, Honda Motor Company had a buried underground storage tank which was
removed under the supervision of Dames & Moore, Inc., a Rolling Meadows,
Illinois based environmental consulting firm. Following the completion of the
work the State of Illinois Environmental Protection Agency issued a letter dated
November 22, 1995 indicating that it had determined that all of the requirements
of Title EVI of the Act and 35 Illinois Administrative Code Part 732 had
apparently been satisfied and that no further action was necessary with respect
to this tank.

823 COMMERCE DRIVE, OAK BROOK, ILLINOIS:

Part of the rehabilitation of the hearing, ventilating, and air conditioning
system include the removal of approximately twenty-five asbestos fittings from
the cold water lines extending from the pumps to the children in the penthouse.
The work was performed by Luse Asbestos Removal Company, of Melrose Park,
Illinois and was performed in March 1996.

777 EAST EISENHOWER PARKWAY, ANN ARBOR, MICHIGAN:

A 2,000 gallon underground storage tank is located at the property which is used
for storage of diesel for an emergency generator. The property's UST is
registered with the State of Michigan and passed a tightness test on November 4,
1996.

OTHER MATTERS RELATED TO EQUITY PARTNERS, LTD.:

In 1988, JMG Lake Bluff Limited Partnership, acquired property located at 6750
South Sayre, Bedford Park, Illinois, which required remediation work to clean-up
a loading dock area. The areas had been contaminated by the spillage of un-used
motor oil prior to the date of acquisition. The remediation program and
installation of improvements were designed to prevent recurrence of the problem,
were funded by the property seller and the tenant, and were completed in 1989
under the supervision of O'Brien & Associates, Inc., and environmental
consulting firm retained by the mortgagee of the property. Equity Partners Ltd.
was the corporate general partner of this Partnership, and the Company merged
with the Equity Partners Ltd. in 1996.

COMPANY MAINTENANCE ACTIVITIES:

Regular cleaning and maintenance activities in the Company's properties require
handling and use of products that may contain "Contaminants," but the Company
has no knowledge after due inquire of any "handling" or "use" that would result
in a violation of an Environmental Law.

ONE PARK PLAZA, MILWAUKEE, WISCONSIN

A 550 gallon underground diesel fuel storage tank associated with a backup
generator is located on the property. The property is identified on the
Wisconsin Department of Commerce UST database. According to three separate phase
I site assessment reports, (the first prepared on behalf of Great Lakes REIT in
advance of its purchase of the property, the second at the time of

<PAGE>

Great Lakes REIT's initial public offering, and the third on behalf of a secured
lender), a leak associated with the tank's piping occurred in 1992. Thereafter
approximately 6 cubic yards of soil were removed from the site and landfilled in
1994. Soil samples were then collected and analyzed, and no further contaminants
were detected. No further action was deemed necessary. The conclusion of each
Phase I report was that the site is in compliance with applicable federal, state
and local requirements.
