the Agent a written confirmation, if such confirmation is requested by the Agent
or any Lender, of each telephonic notice signed by an Authorized Officer. If the
written confirmation differs in any material respect from the action taken by
the Agent and the Lenders, the records of the Agent and the Lenders shall govern
absent manifest error.

      2.14 INTEREST PAYMENT DATES; INTEREST AND FEE BASIS. Interest accrued on
each Portion shall be payable on each Payment Date, commencing with the first
such Payment Date to occur after the Closing Date, on any date on which a
Portion is prepaid, whether due to acceleration or otherwise, and on the
Maturity Date. Notwithstanding the foregoing, interest accrued on that portion
of the outstanding principal amount of any Floating Rate Portion converted into
a Eurodollar Portion on a day other than a Payment Date shall

                                       15
<Page>

be payable on the date of conversion. Interest shall be calculated for actual
days elapsed on the basis of a 360-day year. Interest shall be payable for the
day a Portion is established but not for the day of any payment on the amount
paid if payment is received prior to noon (local time) at the place of payment.
If any payment of principal of or interest on a Portion shall become due on a
day which is not a Business Day, such payment shall be made on the next
succeeding Business Day and, in the case of a principal payment, such extension
of time shall be included in computing interest in connection with such payment.

      2.15 NOTIFICATION OF INTEREST RATES AND PREPAYMENTS. Promptly after
receipt thereof, the Agent will notify each Lender of the contents of the
Initial Notice, any Conversion/Continuation Notice and any repayment notice
received by it hereunder. The Agent will notify each Lender of the interest rate
applicable to each Eurodollar Portion promptly upon determination of such
interest rate and will give each Lender prompt notice of each change in the
Alternate Base Rate.

      2.16 LENDING INSTALLATIONS. Each Lender may book its Loans at any Lending
Installation selected by such Lender and may change its Lending Installation
from time to time. All terms of this Agreement shall apply to any such Lending
Installation and the Loans and any Notes issued hereunder shall be deemed held
by each Lender for the benefit of any such Lending Installation. Each Lender
may, by written notice to the Agent and the Borrower in accordance with Article
XIII, designate replacement or additional Lending Installations for whose
account Loan payments are to be made.

      2.17 NON-RECEIPT OF FUNDS BY THE AGENT. Unless the Borrower notifies the
Agent prior to the date on which it is scheduled to make payment to the Agent of
a payment of principal, interest or fees to the Agent for the account of the
Lenders, that it does not intend to make such payment, the Agent may assume that
such payment has been made. The Agent may, but shall not be obligated to, make
the amount of such payment available to the intended recipient in reliance upon
such assumption. If the Borrower has not in fact made such payment to the Agent,
the recipient of such payment shall, on demand by the Agent, repay to the Agent
the amount so made available together with interest thereon in respect of each
day during the period commencing on the date such amount was so made available
by the Agent until the date the Agent recovers such amount at a rate per annum
equal to in the case of payment by the Borrower, the interest rate applicable to
the relevant Loan.

      2.18 USURY. All agreements herein are expressly limited so that in no
contingency or event whatsoever, whether by reason of the disbursement of the
proceeds of the Loans, the acceleration of the maturity of the unpaid principal
balance of the Loans, or otherwise, shall the amount paid or agreed to be paid
to the Lenders for the use, forbearance or detention of the money to be advanced
under the Loan exceed the highest lawful rate permissible under applicable usury
laws. If, from any circumstances whatsoever, the fulfillment of any provision of
this Agreement or any of the other Loan Documents, at the time performance of
such provision shall be due, shall involve transcending the limit of validity
prescribed by law which a court of competent jurisdiction may deem applicable to
the Loan, then, IPSO FACTO, the obligation to be fulfilled shall be reduced to
the limit of such validity;

                                       16
<Page>

and if, from any circumstance, any Lender shall ever receive as interest an
amount which would exceed the highest lawful rate, such amount which would be
excessive interest shall be applied to the reduction of such Lender's portion of
the unpaid principal balance due on the Loan and not to the payment of interest.

      2.19 LATE CHARGES. If any payment of interest or principal is not received
by Agent within five (5) days after the date such payment is due, then at the
option of the Agent, in addition to the remedies conferred upon Agent pursuant
to this Agreement and the other Loan Documents, a late charge of five percent
(5%) of the amount of the regularly scheduled payment or $25.00, whichever is
greater, will be added to the delinquent amount to compensate Agent for the
expense of handling the delinquency for any payment past due in excess of ten
(10) days, regardless of any notice and cure periods. Such Late Charge is an
administrative charge that will be 100% retained by Agent and not paid to the
Lenders.

      2.20 CLOSING COSTS AND EXPENSES. In addition to the commitment fees
payable as provided in Section 2.4 above, Borrower shall pay, on or prior to the
Closing Date, all closing costs and other fees and expenses incurred by Agent in
connection with the Loan (including Appraisal fees, title insurance premiums,
escrow fees, recording fees, out of pocket syndication expenses and attorneys'
fees and expenses), and other expenses as provided herein. Borrower hereby
acknowledges and agrees that the commitment fees do not include payment of any
such costs, fees or expenses.

                                   ARTICLE III

                             YIELD PROTECTION; TAXES

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

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

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

                                       17
<Page>

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

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

      3.2 CHANGES IN CAPITAL ADEQUACY REGULATIONS. If a Lender determines the
amount of capital required or expected to be maintained by such Lender, any
Lending Installation of such Lender or any corporation controlling such Lender
is increased as a result of a Change (as hereinafter defined), then, within 15
days of demand by such Lender, the Borrower shall pay such Lender the amount
necessary to compensate for any shortfall in the rate of return on the portion
of such increased capital which such Lender determines is attributable to this
Agreement or its Loans (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 hereinafter defined), or (ii)
any adoption of or change in any other law, governmental or quasi-governmental
rule, regulation, policy, guideline, interpretation, or directive (whether or
not having the force of law) after the date of this Agreement which affects the
amount of capital required or expected to be maintained by any Lender or any
Lending Installation or any corporation controlling any Lender. "Risk-Based
Capital Guidelines" means (i) the risk-based capital guidelines in effect in the
United States on the date of this Agreement, including transition rules, and
(ii) the corresponding capital regulations promulgated by regulatory authorities
outside the United States implementing the July 1988 report of the Basle
Committee on Banking Regulation and Supervisory Practices Entitled
"International Convergence of Capital Measurements and Capital Standards,"
including transition rules, and any amendments to such regulations adopted prior
to the date of this Agreement.

      3.3 AVAILABILITY OF TYPES OF PORTIONS. If any Lender determines that
maintenance of Eurodollar Portions at a suitable Lending Installation would
violate any applicable law, rule, regulation, or directive, whether or not
having the force of law, or if the Required Lenders determine that (i) deposits
of a type and maturity appropriate to match fund Eurodollar Portions are not
available, or (ii) the interest rate applicable to Eurodollar Portions does not
accurately reflect the cost of making or maintaining Eurodollar Portions, then
the Agent shall suspend the availability of Eurodollar Portions and require any
affected Eurodollar Portions to be repaid or converted to Floating Rate
Portions.

                                       18
<Page>

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

      3.5 TAXES.

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

                  (iii) The Borrower hereby agrees to indemnify the Agent and
            each Lender for the full amount of Taxes or Other Taxes (including,
            without limitation, any Taxes or Other Taxes imposed on amounts
            payable under this Section 3.5) paid by the Agent or such Lender as
            a result of any Loans made by it hereunder, or otherwise in
            connection with its participation in this Agreement 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 3.6.

                  (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 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 the Agent a United States

                                       19
<Page>

            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 3.5 with respect to Taxes imposed by the United States;
            PROVIDED that, should a Non-U.S. Lender which is otherwise exempt
            from or subject to a reduced rate of withholding tax become subject
            to Taxes because of its failure to deliver a form required under
            clause (iv), above, the Borrower shall take such steps as such
            Non-U.S. Lender shall reasonably request to assist such Non-U.S.
            Lender to recover such Taxes.

                  (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 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.

                  (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

                                       20
<Page>

            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 3.5(vii) shall survive
            the payment of the Obligations and termination of this Agreement.

      3.6 LENDER STATEMENTS; SURVIVAL OF INDEMNITY. To the extent reasonably
possible, each Lender shall designate an alternate Lending Installation with
respect to its Eurodollar Portions to reduce any liability of the Borrower to
such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of
Eurodollar Portions under Section 3.3, so long as such designation is not, in
the judgment of such Lender, disadvantageous to such Lender. Each Lender shall
deliver a written statement of such Lender to the Borrower (with a copy to the
Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such
written statement shall set forth in reasonable detail the calculations upon
which such Lender determined such amount and shall be final, conclusive and
binding on the Borrower in the absence of manifest error. Determination of
amounts payable under such Sections in connection with a Eurodollar Portion
shall be calculated as though each Lender funded its Eurodollar Portion through
the purchase of a deposit of the type and maturity corresponding to the deposit
used as a reference in determining the Eurodollar Rate applicable to such Loan,
whether in fact that is the case or not. Unless otherwise provided herein, the
amount specified in the written statement of any Lender shall be payable on
demand after receipt by the Borrower of such written statement. The obligations
of the Borrower under Sections 3.1, 3.2, 3.4 and 3.5 shall survive payment of
the Obligations and termination of this Agreement.

                                   ARTICLE IV

                         CONDITIONS PRECEDENT TO CLOSING

      4.1 APPRAISALS AND REMARGINING.

            (a) As a condition precedent to disbursement of the Loans, Agent
      shall have determined that the Loan-to-Value Ratio shall not be more than
      60%. If for any reason the Loan-to-Value Ratio exceeds 60%, Lenders shall
      have the right to reduce the Maximum Aggregate Amount to an amount at
      which the Loan-to-Value Ratio will not exceed 60%.

            (b) If prior to the Closing Date, the Appraisals have not been
      completed and approved by Agent, Lenders may nonetheless, in their sole
      and absolute discretion, proceed to make the Loans in the Maximum
      Aggregate Amount, provided that if the completed and approved Appraisals
      disclose that the Loan-to-Value Ratio exceeds 60%, Borrower shall, within
      ten (10days after written demand from Agent, make a principal payment to
      Agent in the amount by which the outstanding

                                       21
<Page>

      principal balance of the Loans exceeds the amount of Loans that would be
      necessary such that the Loan-to-Value Ratio would not exceed 60%.

      4.2 CONDITIONS PRECEDENT TO CLOSING. The Lenders' obligation to make the
Loans and to perform the remainder of their obligations under this Agreement are
subject to the Lenders' and the Agent's satisfaction of the conditions contained
herein in this Article IV.

      4.3 GENERAL CONDITIONS. Borrower shall have delivered each of the
following items to the Agent for approval and Agent shall have approved the
same:

            (a) The Loan Documents;

            (b) Three copies of a plat of survey of each Collateral Property
      (collectively, the "Surveys") prepared and certified by a registered
      surveyor licensed in Illinois in compliance with the minimum detail
      requirements most recently established by ALTA/ACSM (for a Class A
      Survey), including, without limitation: the boundaries and legal
      descriptions of the land comprising each Collateral Property; the location
      of all existing buildings, parking areas and other improvements on such
      land; the area of such land in square feet and acres (to the nearest one
      one-hundredth of an acre); the location of all set-back lines,
      rights-of-way, easements and public utilities located on such land; the
      location of all abutting roadways, streets, and alleys; the location of
      utility services and storm drain and sewer facilities; and showing any
      encroachments by improvements on such land over easements or adjoining
      property and showing any encroachments from adjoining property onto such
      land. The Surveys shall be as of a current date and shall be certified in
      favor of Agent and the Title Company. All matters shown on the Surveys
      must be acceptable to Agent.

            (c ) Evidence that the following insurance coverages are in effect

                  property damage liability coverages in amounts not less than
                  $2,000,000 (combined single limit), and an excess/umbrella
                  liability coverage in an amount not less than $10,000,000
                  shall be in effect with respect to Borrower. Such policies
                  must be written on an occurrence basis so as to provide
                  blanket contractual liability, broad form property damage
                  coverage, and coverage for products and completed operations;

            (ii)  "Special Cause of Loss" insurance on the buildings and other
                  improvements constituting the Collateral Properties in amounts

                  than $36,000,000;

            (iii) If applicable, evidence of worker's compensation insurance
                  coverage satisfactory to Agent;

                  by the Department of Housing and Urban Development, a National
                  Flood Insurance Association standard flood insurance policy,
                  plus insurance from a private insurance carrier if necessary,
                  for the duration of the Loans in the amount of the full
                  insurable value of the Collateral Properties; and

            (v)   Such other insurance as Agent may reasonably require, which
                  may include, without limitation, errors and omissions
                  insurance with respect to the contractors, architects and
                  engineers, rent abatement and/or business loss insurance.

      a rating of "A" VII or better by A.M. Best Co., in Best's Rating Guide,
      (w) name Agent as an additional insured on all liability insurance and as
      mortgagee and loss payee on all casualty insurance, (x) provide that Agent
      is to receive thirty (30) days written notice prior to non-renewal or
      cancellation, (y) be evidenced by a certificate of insurance to be held by
      Agent, and (z)be in form and amounts reasonably acceptable to Agent.

            (d) Fee and Leasehold Loan Policies of Title Insurance issued by the

                         REPRESENTATIONS AND WARRANTIES

      Borrower represents and warrants to the Lenders that:

      5.1 EXISTENCE AND STANDING. Borrower is a limited liability company duly
and properly 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 its business is conducted. Great Lakes LP

good standing under the laws of its jurisdiction of organization and has all
requisite authority to conduct its business in each jurisdiction in which its
business is conducted. Great Lakes REIT is a trust duly and properly organized,
validly existing and in good standing under the laws of its jurisdiction of

jurisdiction in which its business is conducted

      5.2 AUTHORIZATION AND VALIDITY. Borrower has the power and authority and
legal right to execute and deliver the Loan Documents to which it is a party and
to perform its obligations thereunder. The execution and delivery by Borrower of
the Loan Documents to which it is a party and the performance of its obligations
thereunder have been duly authorized by proper limited liability company action,
and the Loan Documents to which Borrower is a party constitute legal, valid and
binding obligations of Borrower enforceable against Borrower in accordance with
their terms, except as enforceability may be limited by bankruptcy, equity,
insolvency or similar laws affecting the enforcement of creditors' rights
generally. The Guarantors have the power and authority and legal right to
execute and deliver the Loan Documents to which they are a party and to perform
their obligations thereunder. The execution and delivery by the Guarantors of
the Loan Documents to which they are a party and the performance of their
obligations thereunder have been duly authorized by proper partnership and
corporate action, as applicable, and the Loan Documents to which the Guarantors
are a party constitute legal, valid and binding obligations of the Guarantors
enforceable against the Guarantors in accordance with their terms, except as
enforceability may be limited by bankruptcy, equity, insolvency or similar laws
affecting the enforcement of creditors' rights generally.

      5.3 NO CONFLICT; GOVERNMENT CONSENT. Neither the execution and delivery by
Borrower or either Guarantor of the Loan Documents to which each is a party, nor
the consummation of the transactions therein contemplated, nor compliance with
the provisions thereof will (a) violate (i) any law, rule, regulation, order,
writ, judgment, injunction, decree or award binding on Borrower or either
Guarantor, or (ii) Borrower's or either Guarantor's operating agreement,
partnership agreement, trust agreement, by-laws, articles of organization or
formation, or certificate of limited partnership, as the case may be, or (iii)
the provisions of any indenture, instrument or agreement to which Borrower or
either Guarantor is a party or is subject, or by which it, or its Property, is
bound, or (b) conflict with or constitute a default thereunder, or result in, or
require, the creation or imposition of

                                       26
<Page>

any Lien in, of or on the Property of Borrower or either Guarantor pursuant to
the terms of any such indenture, instrument or agreement. No order, consent,
adjudication, approval, license, authorization, or validation of, or filing,
recording or registration with, or exemption by, or other action in respect of
any governmental or public body or authority, or any subdivision thereof, which
has not been obtained by Borrower or either Guarantor, is required to be
obtained by Borrower or either Guarantor in connection with the execution and
delivery of the Loan Documents, the borrowings under this Agreement, the payment
and performance by the Borrower of the Obligations, the payment and performance
by Guarantors of their obligations under the Guaranty and the Environmental
Indemnity or the legality, validity, binding effect or enforceability of any of
the Loan Documents.

      5.4 FINANCIAL STATEMENTS. All financial statements submitted to Lender
relating to Borrower, the Guarantors and the Collateral Properties are true,
complete and correct, and have been prepared in accordance with general
accounting principles consistently applied and fairly present the financial
condition of the Person or Property to which they pertain and the other
information therein described and do not contain any untrue statement of a
material fact or omit to state a fact material to the financial statement
submitted or this Agreement. Borrower and each Guarantor are solvent and able to
pay their respective debts as such debts become due, and they have capital
sufficient to carry on their respective present businesses and transactions and
all businesses and transactions in which they are about to engage. None of
Borrower or any Guarantor (i) is bankrupt or insolvent, (ii) has made an
assignment for the benefit of its or his creditors, (iii) has had a trustee or
receiver appointed, (iv) has had any bankruptcy, reorganization or insolvency
proceedings instituted by or against it or him, or (v) shall be rendered
insolvent by its execution, delivery or performance of this Agreement or the
Loan Documents or by the transactions contemplated hereunder and thereunder.

      5.5 MATERIAL ADVERSE CHANGE. Since August 1, 2002, there has been no
change in the business, Property, condition (financial or otherwise) or results
of operations of the Borrower, the Guarantors or the Collateral Properties which
could reasonably be expected to have a Material Adverse Effect.

      5.6 TAXES. The Guarantors have filed all United States federal tax returns
and all other tax returns which are required to be filed and have paid all taxes
due pursuant to said returns or pursuant to any assessment received by the
Guarantors, except such taxes, if any, as are being contested in good faith and
as to which adequate reserves have been provided in accordance with Agreement
Accounting Principles and as to which no Lien exists. No tax liens have been
filed and no claims are being asserted with respect to any such taxes. The
charges, accruals and reserves on the books of the Guarantors in respect of any
taxes or other governmental charges are adequate. Borrower qualifies for
partnership tax treatment under United States federal tax law.

      5.7 LITIGATION AND CONTINGENT OBLIGATIONS. There is no litigation,
arbitration, governmental investigation, proceeding or inquiry pending or, to
the knowledge of any of their officers, threatened against or affecting
Borrower, either Guarantor or any of the Collateral Properties which could


                                       27
<Page>

reasonably be expected to have a Material Adverse Effect or which seeks to
prevent, enjoin or delay the making of the Loans. Other than any liability
incident to any litigation, arbitration or proceeding which could not reasonably
be expected to have a Material Adverse Effect, the Borrower and the Guarantors
have no material contingent obligations not provided for or disclosed in the
financial statements referred to in Section 5.4.

      5.8 ERISA. There are no Unfunded Liabilities of any Single Employer Plans.
None of the Borrower, either Guarantor or any other member of the Controlled
Group has incurred, or is reasonably expected to incur, any withdrawal liability
to Multiemployer Plans. Each Plan complies in all material respects with all
Applicable Laws, no Reportable Event has occurred with respect to any Plan, none
of the Borrower, either Guarantor or any other member of the Controlled Group
has withdrawn from any Plan or initiated steps to do so, and no steps have been
taken to reorganize or terminate any Plan. Borrower is not an entity deemed to
hold "plan assets" within the meaning of 29 C.F.R. ss. 2510.3-101 of an employee
benefit plan (as defined in Section 3(3) of ERISA) which iS subject to Title I
of ERISA or any plan (within the meaning of Section 4975 of the Code), and
neither the execution of this Agreement nor the making of Loans hereunder gives
rise to a prohibited transaction within the meaning of Section 406 of ERISA or
Section 4975 of the Code.

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

      5.10 MATERIAL AGREEMENTS. Neither the Borrower nor either Guarantor is a
party to any agreement or instrument or subject to any charter or other limited
liability, company, partnership, trust restriction which could reasonably be
expected to have a Material Adverse Effect. Neither the Borrower nor either
Guarantor is in default in the performance, observance or fulfillment of any of
the obligations, covenants or conditions contained in (i) any agreement to which
it is a party, which default could reasonably be expected to have a Material
Adverse Effect, or (ii) any agreement or instrument evidencing or governing
Indebtedness in excess of $10,000,000.

      5.11 COMPLIANCE WITH LAWS. The Collateral Properties and the use,
occupancy and operation thereof for their existing purposes do not violate the
Ground Leases or any Applicable Laws (including without limitation, those
relating to environmental protection, water use, zoning, building, fire, health
or safety or the Americans with Disabilities Act), any contractual arrangements
with third parties or any covenants, conditions, easements, rights of way or
restrictions of record. None of Borrower, any Guarantor or any agent thereof has
received any notice, written or otherwise, alleging any such violation, which
violation has not previously been cured. The Collateral Properties are in full
compliance and conformity with all zoning requirements, including without
limitation, those relating to setbacks, height, parking, floor area ratio, fire
lanes and percentage of land coverage. No right to any off-site facilities is
necessary to insure compliance by the Collateral Properties with all
environmental protection,

                                       28
<Page>

public highway, water use, zoning, building, fire, health, safety or similar
statutes, laws, ordinances, codes, rules, regulations, orders and decrees. There
has not been committed by or on behalf of Borrower, or to Borrower's knowledge,
any other Person in occupancy of or involved with the operation of use of any of
the Collateral Properties, any act or omission affording the Federal Government
or any state or local government the right of forfeiture against any of the
Collateral Properties or any portion thereof or any monies paid in performance
of its obligations under any of the Loan Documents. Borrower does not have any
outstanding Indebtedness other than the Loans.

      5.12 ENVIRONMENTAL MATTERS. Neither Borrower nor either Guarantor has
received any notice to the effect that its operations are not in material
compliance with any of the requirements of applicable Environmental Laws or are
the subject of any federal or state investigation evaluating whether any
remedial action is needed to respond to a release of any toxic or hazardous
waste or substance into the environment, which non-compliance or remedial action
could reasonably be expected to have a Material Adverse Effect. Except as
described in the Environmental Report, no Hazardous Materials have been
generated, released, stored or deposited over, beneath or on the Collateral
Properties or in any structure located on the Collateral Properties. To the best
of Borrower's knowledge and except as described in the Environmental Report, no
Hazardous Materials have been used or will be used in the construction of all or
any portion of the Collateral Properties, nor, has any part of the Collateral
Properties been used for or as a land fill, the result of which could impose any
liability against Borrower, Agent, Lenders or the Collateral Properties under
any Applicable Law or regulation. Borrower covenants that it shall indemnify,
hold harmless and defend Agent, for the benefit of the Lenders, from any and all
claims, losses, damages, response costs and expenses (collectively, "Claims")
arising out of or in any way relating to the past, present or future presence,
removal or disposal of any Hazardous Materials over, beneath, in or on the
Collateral Properties regardless of whether such presence, removal or disposal
constitutes a breach of the representations, warranties, covenants and
agreements set forth in this Sections, including, but not limited to: (a) claims
of third parties (including governmental agencies) for damages, penalties,
response costs, injunctive or other relief; (b) costs of removal and
restoration, including fees of attorneys and experts and costs of reporting the
existence of any Hazardous Materials to any governmental agency; and (c) any and
all expenses or obligations incurred at, before and after any trial or appeal
therefrom, including without limitation, reasonable attorneys' fees, witness
fees, deposition costs, photocopying charges and other expenses, all of which
shall be paid by Borrower when incurred.

with respect to Borrower or either Guarantor, the Obligations shall immediately
become due and payable without any election or action on the part of the Agent

and payable, whereupon the Obligations shall become immediately due and payable,

Required Lenders (or the Agent with the consent in writing of the Required
Lenders) and the Borrower may enter into agreements supplemental hereto for the
purpose of adding or modifying any provisions to the Loan Documents or changing

<Page>

      8.3 PRESERVATION OF RIGHTS. No delay or omission of the Lenders or the
Agent to exercise any right under the Loan Documents shall impair such right or
be construed to be a waiver of any Default or an acquiescence therein. Any
single or partial exercise of any such right shall not preclude other or further

other variation of the terms, conditions or provisions of the Loan Documents
whatsoever shall be valid unless in writing signed by Agent or the Lenders
required pursuant to Section 8.2, and then only to the extent in such writing
specifically set forth. All remedies contained in the Loan Documents or by law
afforded shall be cumulative and all shall be available to the Agent and the
Lenders until the Obligations have been paid in full.

                  negligence or willful misconduct of the party seeking
                  indemnification. The obligations of the Borrower under this

judgment by a court of competent jurisdiction to have arisen from the gross
negligence or willful misconduct of such Person.

of its directors, officers, agents or employees shall be responsible for or have
any duty to ascertain, inquire into, or verify (a) any statement, warranty or

Lender; (c) the satisfaction of any condition specified in Article IV, except
receipt of items required to be delivered solely to the Agent; (d) the existence
or possible existence of any Default or Unmatured Default; (e) the validity,
enforceability, effectiveness, sufficiency or genuineness of any Loan Document
or any other instrument or writing furnished in connection therewith; (f) the
value, sufficiency, creation, perfection or priority of any Lien in any
collateral security; or (g) the financial condition of the Borrower or either
Guarantor of any of the Obligations or of any of the Borrower's or any such
Guarantor's respective subsidiaries. The Agent shall have no duty to disclose to
the Lenders information that is not required to be furnished by the Borrower to
the Agent at such time, but is voluntarily furnished by the Borrower to the
Agent (either in its capacity as Agent or in its individual capacity).

                                       41

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

      10.6 EMPLOYMENT OF AGENTS AND COUNSEL. The Agent may execute any of its
duties as Agent hereunder and under any other Loan Document by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the
Lenders, except as to money or securities received by it or its authorized
agents, for the default or misconduct of any such agents or attorneys-in-fact
selected by it with reasonable care. The Agent shall be entitled to advice of
counsel concerning the contractual arrangement between the Agent and the Lenders
and all matters pertaining to the Agent's duties hereunder and under any other
Loan Document.

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

      10.8 AGENT'S REIMBURSEMENT AND INDEMNIFICATION. The Lenders agree to
reimburse and indemnify the Agent ratably in proportion to their respective
Loans outstanding (i) for any amounts not reimbursed by the Borrower for which
the Agent is entitled to reimbursement by the Borrower under the Loan Documents,
(ii) for any other expenses incurred by the Agent on behalf of the Lenders, in
connection with the preparation, execution, delivery, administration and
enforcement of the Loan Documents (including, without limitation, for any
expenses incurred by the Agent in connection with any dispute between the Agent
and any Lender or between two or more of the Lenders) and (iii) for any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind and nature whatsoever which may be
imposed on, incurred by or asserted against the Agent in any way relating to or
arising out of the Loan Documents or any other document delivered in connection
therewith or the transactions contemplated thereby (including, without
limitation, for any such amounts incurred by or asserted against the Agent in
connection with any dispute between the Agent and any Lender or between two or
more of the Lenders), or the enforcement of any of the terms of the Loan
Documents or of any such other documents, PROVIDED that (i) no Lender shall be
liable for any of the foregoing to the extent any of the foregoing is found in a
final non-appealable judgment by a court of competent jurisdiction to have
resulted from the gross negligence or willful misconduct of the Agent and (ii)
any indemnification required pursuant to Section 3.5(vii) shall, notwithstanding


                                       42
<Page>

the provisions of this Section 10.8, be paid by the relevant Lender in
accordance with the provisions thereof. The obligations of the Lenders under
this Section 10.8 shall survive payment of the Obligations and termination of
this Agreement.

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

      10.10 RIGHTS AS A LENDER. In the event the Agent is a Lender, the Agent
shall have the same rights and powers hereunder and under any other Loan
Document with respect to its Commitment and its Loans as any Lender and may
exercise the same as though it were not the Agent, and the term "Lender" or
"Lenders" shall, at any time when the Agent is a Lender, unless the context
otherwise indicates, include the Agent in its individual capacity. The Agent and
its Affiliates may accept deposits from, lend money to, and generally engage in
any kind of trust, debt, equity or other transaction, in addition to those
contemplated by this Agreement or any other Loan Document, with the Borrower or
either Guarantor in which the Borrower or such Guarantor is not restricted
hereby from engaging with any other Person. The Agent, in its individual
capacity, is not obligated to remain a Lender.

      10.11 LENDER CREDIT DECISION. Each Lender acknowledges that it has,
independently and without reliance upon the Agent 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 decisions in
taking or not taking action under this Agreement and the other Loan Documents.

      10.12 SUCCESSOR AGENT. The Agent may resign at any time by giving written
notice thereof to the Lenders and the Borrower, such resignation to be effective
upon the appointment of a successor Agent or, if no successor Agent has been
appointed, forty-five days after the retiring Agent gives notice of its
intention to resign. The Agent may be removed at any time with or without cause
by written notice received by the Agent from the Required Lenders, such removal
to be effective on the date specified by the Required Lenders. Upon any such
resignation or removal, the Required Lenders shall have the right to appoint, on
behalf of the Borrower and the Lenders, a successor Agent. If no successor Agent
shall have been so appointed by the Required Lenders within thirty days after
the resigning Agent's giving notice of its intention to resign, then the
resigning Agent may appoint, on behalf of the Borrower and the Lenders, a
successor Agent. Notwithstanding the previous sentence, the Agent may at any
time without the consent of the Borrower or any Lender, appoint any of its
Affiliates which is a commercial bank as a successor Agent hereunder. If the
Agent has resigned or been removed and no successor Agent has been appointed,
the Lenders may perform

                                       43
<Page>

all the duties of the Agent hereunder and the Borrower shall make all payments
in respect of the Obligations to the applicable Lender and for all other
purposes shall deal directly with the Lenders. No successor Agent shall be
deemed to be appointed hereunder until such successor Agent has accepted the
appointment. Any such successor Agent shall be a commercial bank having capital
and retained earnings of at least $100,000,000. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the resigning or removed Agent. Upon the effectiveness of the
resignation or removal of the Agent, the resigning or removed Agent shall be
discharged from its duties and obligations hereunder and under the Loan
Documents. After the effectiveness of the resignation or removal of an Agent,
the provisions of this Article X shall continue in effect for the benefit of
such Agent in respect of any actions taken or omitted to be taken by it while it
was acting as the Agent hereunder and under the other Loan Documents. In the
event that there is a successor to the Agent by merger, or the Agent assigns its
duties and obligations to an Affiliate pursuant to this Section 10.12, then the
term "Prime Rate" as used in this Agreement shall mean the prime rate, base rate
or other analogous rate of the new Agent.

      10.13 DELEGATION TO AFFILIATES. The Borrower and the Lenders agree that
the Agent may delegate any of its duties under this Agreement to any of its
Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents
and employees) which performs duties in connection with this Agreement shall be
entitled to the same benefits of the indemnification, waiver and other
protective provisions to which the Agent is entitled under Articles IX and X.

      10.14 COLLATERAL PROPERTY RELEASES. The Lenders hereby empower and
authorize the Agent to execute and deliver to the Borrower on their behalf any
agreements, documents or instruments as shall be necessary or appropriate to
effect any releases of a Property Collateral which shall be permitted by the
terms hereof or of any other Loan Document or which shall otherwise have been
approved by the Required Lenders.

                                   ARTICLE XI

                            SETOFF; RATABLE PAYMENTS

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

      11.2 RATABLE PAYMENTS. If any Lender, whether by setoff or otherwise, has
payment made to it upon its Loans (other than payments received pursuant to
Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any
other Lender, such Lender agrees, promptly upon demand, to purchase a

                                       44
<Page>

portion of the Loans held by the other Lenders so that after such purchase each
Lender will hold its ratable proportion of Loans. If any Lender, whether in
connection with setoff or amounts which might be subject to setoff or otherwise,
receives collateral or other protection for its Obligations or such amounts
which may be subject to setoff, such Lender agrees, promptly upon demand, to
take such action necessary such that all Lenders share in the benefits of such
collateral ratably in proportion to their Loans. In case any such payment is
disturbed by legal process, or otherwise, appropriate further adjustments shall
be made.

                                   ARTICLE XII

                BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS

      12.1 SUCCESSORS AND ASSIGNS. The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and their respective successors and assigns permitted hereby, except
that (i) the Borrower shall not have the right to assign its rights or
obligations under the Loan Documents without the prior written consent of each
Lender, (ii) any assignment by any Lender must be made in compliance with
Section 12.3, and (iii) any transfer by Participation must be made in compliance
with Section 12.2. Any attempted assignment or transfer by any party not made in
compliance with this Section 12.1 shall be null and void, unless such attempted
assignment or transfer is treated as a participation in accordance with Section
12.3.2. The parties to this Agreement acknowledge that clause (ii) of this
Section 12.1 relates only to absolute assignments and this Section 12.1 does not
prohibit assignments creating security interests, including, without limitation,
(x) any pledge or assignment by any Lender of all or any portion of its rights
under this Agreement and any Note to a Federal Reserve Bank or (y) in the case
of a Lender which is a Fund, any pledge or assignment of all or any portion of
its rights under this Agreement and any Note to its trustee in support of its
obligations to its trustee; PROVIDED, HOWEVER, that no such pledge or assignment
creating a security interest shall release the transferor Lender from its
obligations hereunder unless and until the parties thereto have complied with
the provisions of Section 12.3. The Agent may treat the Person which made any
Loan or which holds any Note as the owner thereof for all purposes hereof unless
and until such Person complies with Section 12.3; PROVIDED, HOWEVER, that the
Agent may in its discretion (but shall not be required to) follow instructions
from the Person which made any Loan or which holds any Note to direct payments
relating to such Loan or Note to another Person. Any assignee of the rights to
any Loan or any Note agrees by acceptance of such assignment to be bound by all
the terms and provisions of the Loan Documents. Any request, authority or
consent of any Person, who at the time of making such request or giving such
authority or consent is the owner of the rights to any Loan (whether or not a
Note has been issued in evidence thereof), shall be conclusive and binding on
any subsequent holder or assignee of the rights to such Loan.

      12.2 PARTICIPATIONS.

            12.2.1 PERMITTED PARTICIPANTS; EFFECT. Any Lender may at any time
      sell to one or more banks or other entities ("Participants") participating
      interests in the Loan owing to such Lender, any Note held

                                       45
<Page>

      by such Lender or any other interest of such Lender under the Loan
      Documents. In the event of any such sale by a Lender of participating
      interests to a Participant, such Lender's obligations under the Loan
      Documents shall remain unchanged, such Lender shall remain solely
      responsible to the other parties hereto for the performance of such
      obligations, such Lender shall remain the owner of its Loan and the holder
      of any Note issued to it in evidence thereof for all purposes under the
      Loan Documents, all amounts payable by the Borrower under this Agreement
      shall be determined as if such Lender had not sold such participating
      interests, and the Borrower and the Agent shall continue to deal solely
      and directly with such Lender in connection with such Lender's rights and
      obligations under the Loan Documents.

            12.2.2 VOTING RIGHTS. Each Lender shall retain the sole right to
      approve, without the consent of any Participant, any amendment,
      modification or waiver of any provision of the Loan Documents other than
      any amendment, modification or waiver with respect to any Loan in which
      such Participant has an interest which would require consent of all of the
      Lenders pursuant to the terms of Section 8.2 or of any other Loan
      Document.

            12.2.3 BENEFIT OF CERTAIN PROVISIONS. The Borrower agrees that each
      Participant shall be deemed to have the right of setoff provided in
      Section 11.1 in respect of its participating interest in amounts owing
      under the Loan Documents to the same extent as if the amount of its
      participating interest were owing directly to it as a Lender under the
      Loan Documents, PROVIDED that each Lender shall retain the right of setoff
      provided in Section 11.1 with respect to the amount of participating
      interests sold to each Participant. The Lenders agree to share with each
      Participant, and each Participant, by exercising the right of setoff
      provided in Section 11.1, agrees to share with each Lender, any amount
      received pursuant to the exercise of its right of setoff, such amounts to
      be shared in accordance with Section 11.2 as if each Participant were a
      Lender. The Borrower further agrees that each Participant shall be
      entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 to the same
      extent as if it were a Lender and had acquired its interest by assignment
      pursuant to Section 12.3, PROVIDED that (i) a Participant shall not be
      entitled to receive any greater payment under Section 3.1, 3.2 or 3.5 than
      the Lender who sold the participating interest to such Participant would
      have received had it retained such interest for its own account, unless
      the sale of such interest to such Participant is made with the prior
      written consent of the Borrower, and (ii) any Participant not incorporated
      under the laws of the United States of America or any State thereof agrees
      to comply with the provisions of Section 3.5 to the same extent as if it
      were a Lender.

      12.3 ASSIGNMENTS.

            12.3.1 PERMITTED ASSIGNMENTS. Any Lender may at any time assign to
      one or more banks or other entities ("Purchasers") all or any part of its
      rights and obligations under the Loan Documents. Such assignment shall be
      substantially in the form of Exhibit B or in such other form as may be
      agreed to by the parties thereto. Each such assignment with respect to a
      Purchaser which is not a Lender or an

                                       46
<Page>

      Affiliate of a Lender or an Approved Fund shall either be in an amount
      equal to the entire applicable Commitment and Loans of the assigning
      Lender or (unless each of the Borrower and the Agent otherwise consents)
      be in an aggregate amount not less than $5,000,000.

            12.3.2 CONSENTS. The consent of the Agent shall be required prior to
      an assignment becoming effective unless the Purchaser is a Lender, an
      Affiliate of a Lender or an Approved Fund. Any consent required under this
      Section 12.3.2 shall not be unreasonably withheld or delayed.

            12.3.3 EFFECT; EFFECTIVE DATE. Upon (i) delivery to the Agent of an
      assignment, together with any consents required by Sections 12.3.1 and
      12.3.2, and (ii) payment of a $3,500 fee to the Agent for processing such
      assignment (unless such fee is waived by the Agent), such assignment shall
      become effective on the effective date specified in such assignment. The
      assignment shall contain a representation by the Purchaser to the effect
      that none of the consideration used to make the purchase of the Commitment
      and Loans under the applicable assignment agreement constitutes "plan
      assets" as defined under ERISA and that the rights and interests of the
      Purchaser in and under the Loan Documents will not be "plan assets" under
      ERISA. On and after the effective date of such assignment, such Purchaser
      shall for all purposes be a Lender party to this Agreement and any other
      Loan Document executed by or on behalf of the Lenders and shall have all
      the rights and obligations of a Lender under the Loan Documents, to the
      same extent as if it were an original party thereto, and the transferor
      Lender shall be released with respect to the Commitment and Loans assigned
      to such Purchaser without any further consent or action by the Borrower,
      the Lenders or the Agent. In the case of an assignment covering all of the
      assigning Lender's rights and obligations under this Agreement, such
      Lender shall cease to be a Lender hereunder but shall continue to be
      entitled to the benefits of, and subject to, those provisions of this
      Agreement and the other Loan Documents which survive payment of the
      Obligations and termination of the applicable agreement. Any assignment or
      transfer by a Lender of rights or obligations under this Agreement that
      does not comply with this Section 12.3 shall be treated for purposes of
      this Agreement as a sale by such Lender of a participation in such rights
      and obligations in accordance with Section 12.2. Upon the consummation of
      any assignment to a Purchaser pursuant to this Section 12.3.3, the
      transferor Lender, the Agent and the Borrower shall, if the transferor
      Lender or the Purchaser desires that its Loans be evidenced by Notes, make
      appropriate arrangements so that new Notes or, as appropriate, replacement
      Notes are issued to such transferor Lender and new Notes or, as
      appropriate, replacement Notes, are issued to such Purchaser, in each case
      in principal amounts reflecting their respective Commitments, as adjusted
      pursuant to such assignment.

            12.3.4 REGISTER. The Agent, acting solely for this purpose as an
      agent of the Borrower, shall maintain at one of its offices in Chicago,
      Illinois a copy of each Assignment and Assumption delivered to it and a
      register for the recordation of the names and addresses of the Lenders,
      and the Commitments of, and principal amounts of the Loans

                                       47
<Page>

      owing to, each Lender pursuant to the terms hereof from time to time (the
      "Register"). The entries in the Register shall be conclusive, and the
      Borrower, the Agent and the Lenders may treat each Person whose name is
      recorded in the Register pursuant to the terms hereof as a Lender
      hereunder for all purposes of this Agreement, notwithstanding notice to
      the contrary. The Register shall be available for inspection by the
      Borrower and any Lender, at any reasonable time and from time to time upon
      reasonable prior notice.

      12.4 DISSEMINATION OF INFORMATION. The Borrower authorizes each Lender to
disclose to any Participant or Purchaser or any other Person acquiring an
interest in the Loan Documents by operation of law (each a "Transferee") and any
prospective Transferee any and all information in such Lender's possession
concerning the creditworthiness of the Borrower and its Subsidiaries, including
without limitation any information contained in any Reports; PROVIDED that each
Transferee and prospective Transferee agrees to be bound by Section 9.11 of this
Agreement.

      12.5 TAX TREATMENT. If any interest in any Loan Document is transferred to
any Transferee which is not incorporated under the laws of the United States or
any State thereof, the transferor Lender shall cause such Transferee,
concurrently with the effectiveness of such transfer, to comply with the
provisions of Section 3.5(iv).

                                  ARTICLE XIII

                                     NOTICES

      13.1 NOTICES. Except as otherwise permitted with respect to
Continuation/Conversion Notices, all notices, requests and other communications
to any party hereunder shall be in writing (including electronic transmission,
facsimile transmission or similar writing) and shall be given to such party: (x)
in the case of the Borrower or the Agent, at its address or facsimile number set
forth on the signature pages hereof, (y) in the case of any Lender, at its
address or facsimile number set forth below its signature hereto or (z) in the
case of any party, at such other address or facsimile number as such party may
hereafter specify for the purpose by notice to the Agent and the Borrower in
accordance with the provisions of this Section 13.1. Each such notice, request
or other communication shall be effective (i) if given by facsimile
transmission, when transmitted to the facsimile number specified in this Section
and confirmation of receipt is received, or (ii) if given by any other means,
when delivered (or, in the case of electronic transmission, received) at the
address specified in this Section; PROVIDED that notices to the Agent under
Article II shall not be effective until received.

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

                                   ARTICLE XIV

                                  COUNTERPARTS

                                       48
<Page>

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

                                   ARTICLE XV

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

      15.1 CHOICE OF LAW. THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING A
CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH

SEQ, BUT OTHERWISE WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS) OF THE
STATE OF ILLINOIS, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL
BANKS.

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

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