                                                                October 31, 2003

          FOR VALUE RECEIVED, INLAND PARK PLACE LIMITED PARTNERSHIP, an Illinois
limited partnership, having its principal place of business at 2901 Butterfield
Road, Oak Brook, Illinois 60523, a maker hereunder (referred to herein as
"BORROWER"), hereby unconditionally promises to pay to the order of BEAR STEARNS
COMMERCIAL MORTGAGE, INC., a New York corporation, as payee, having an address
at 383 Madison Avenue, New York, New York 10179 ("LENDER"), or at such other
place as the holder hereof may from time to time designate in writing, the
principal sum of THIRTEEN MILLION ONE HUNDRED TWENTY SEVEN THOUSAND AND NO/100
DOLLARS ($13,127,000.00), in lawful money of the United States of America with
interest thereon to be computed from the date of this Note at the Interest Rate,
and to be paid in accordance with the terms of this Note and that certain Loan
Agreement, dated as of the date hereof, between Borrower and Lender (the "LOAN
AGREEMENT"). All capitalized terms not defined herein shall have the respective
meanings set forth in the Loan Agreement.

                            ARTICLE 1 - PAYMENT TERMS

          Borrower agrees to pay interest on the unpaid principal sum of this
Note from time to time outstanding at the rates and at the times specified in
the Loan Agreement and the outstanding balance of the principal sum of this Note
and all accrued and unpaid interest thereon shall be due and payable on the
Maturity Date.

                      ARTICLE 2 - DEFAULT AND ACCELERATION

          The Debt shall without notice become immediately due and payable at
the option of Lender if any payment required in this Note is not paid on or
prior to the date when due or if not paid on the Maturity Date or on the
happening of any other Event of Default.

                           ARTICLE 3 - LOAN DOCUMENTS

          This Note is secured by the Mortgage and the other Loan Documents. All
of the terms, covenants and conditions contained in the Loan Agreement, the
Mortgage and the other Loan Documents are hereby made part of this Note to the
same extent and with the same force as if they were fully set forth herein. In
the event of a conflict or inconsistency between the terms of this Note and the
Loan Agreement, the terms and provisions of the Loan Agreement shall govern.

                           ARTICLE 4 - SAVINGS CLAUSE

          Notwithstanding anything to the contrary contained in this Note or the
Mortgage, neither the Applicable Interest Rate nor the Default Rate shall at any
time exceed the Maximum Rate. The term "Maximum Rate," as used herein, shall
mean, on any day, the highest nonusurious rate of interest (if any) permitted by
applicable law on such day. For purposes of

<Page>

Chapter 303 of the Texas Finance Code, as it may from time to time be amended,
the Maximum Rate shall be the "weekly ceiling" as defined in Section 303.002 of
said Code and as computed in accordance with Section 303.003 of said Code, from
time to time in effect; provided, however, that to the extent permitted by
applicable law, Lender reserves the right to change, from time to time by
further notice and disclosure to Borrower, the ceiling on which the Maximum Rate
is based under Chapter 303 of said Code; and, provided further, that the
"highest nonusurious rate of interest permitted by applicable law" for purposes
of this Note or the Mortgage shall not be limited to the applicable rate ceiling
under Chapter 303 of said Code if federal laws or other state laws now or
hereafter in effect and applicable to this Note or the Mortgage (and the
interest contracted for, charged and collected hereunder) shall permit a higher
rate of interest. In no event shall the Loan be considered a revolving credit
account as defined in Chapter 346 of the Texas Finance Code, as may be hereafter
amended or recodified.

          It is the intention of the parties hereto to comply with the usury
laws of the State of Texas and the United States of America. The parties hereto
do not intend to contract for, charge or receive any interest or other charge
which is usurious, and by execution of this Note or the Mortgage, Borrower
agrees that Lender has no such intent. This Note, the Mortgage, the other Loan
Documents and all other agreements between Borrower and Lender or any other
holder hereof, which are now existing or hereafter arising, whether written or
oral, are hereby expressly limited so that in no event whatsoever, whether by
reason of acceleration of maturity hereof, or otherwise, shall the amount paid,
or agreed to be paid, to Lender or any other holder hereof for the use,
forbearance or detention of the money to be due hereunder or otherwise, or for
the payment or performance of any covenant or obligation contained herein or in
any other document evidencing, securing or pertaining to the Debt, exceed the
Maximum Rate. If from any circumstance whatsoever fulfillment of any provisions
hereof or other document, at the time performance of such provisions shall be
due, shall involve transcending the valid limits prescribed by law, then ipso
facto, the obligation to be fulfilled shall be reduced to the Maximum Rate, and
if from any such circumstance Lender or any other holder shall ever receive as
interest or otherwise an amount which will exceed the Maximum Rate, such amount
which would be excessive interest shall be applied to the reduction of the
principal amount owing hereunder or on account of any other principal
indebtedness of Borrower to the holder and not to the payment of interest, or if
such excessive interest exceeds the unpaid balance of principal hereof and such
other indebtedness, such excess shall be refunded to Borrower. All sums paid and
agreed to be paid to Lender or any other holder for use, forbearance or
detention of the indebtedness of Borrower shall, to the extent permitted by
applicable law, be amortized, prorated, allocated, and spread throughout the
period until payment in full on the Note (or any renewals, extensions and
rearrangement thereof) so that the actual rate of interest on account of the
Debt is uniform throughout the term of this Note (and all renewals, extensions
and rearrangements hereof) and does not exceed the Maximum Rate. The terms and
provisions of this Article 4 shall control and supersede any other provision of
this Note or the other Loan Documents.

                           ARTICLE 5 - NO ORAL CHANGE

          This Note may not be modified, amended, waived, extended, changed,
discharged or terminated orally or by any act or failure to act on the part of
Borrower or Lender, but only by an agreement in writing signed by the party
against whom enforcement of any modification, amendment, waiver, extension,
change, discharge or termination is sought.

                               ARTICLE 6 - WAIVERS

          Borrower and all others who may become liable for the payment of all
or any part of the Debt do hereby severally waive presentment and demand for
payment, notice of dishonor, notice of intention to accelerate, notice of
acceleration, protest and notice of protest and non-payment and all other
notices of any kind. No release of any security for the Debt or extension of
time for payment of this Note or any installment hereof, and no alteration,
amendment or waiver of any provision of this Note, the Loan Agreement or the
other Loan Documents made by agreement between Lender or any other Person shall
release, modify, amend, waive, extend, change, discharge, terminate or affect
the liability of Borrower, and any other Person who may become liable for the
payment of all or any part of the Debt, under this Note, the Loan Agreement or
the other Loan Documents. No notice to or demand on Borrower shall be deemed to
be a waiver of the obligation of Borrower or of the right of Lender to take
further action without further notice or demand as provided for in this Note,
the Loan Agreement or the other Loan Documents. If Borrower is a partnership,
the agreements herein contained shall remain in force and applicable,
notwithstanding any changes in the individuals comprising the partnership, and
the term "Borrower," as used herein, shall include any alternate or successor
partnership, but any predecessor partnership and their partners shall not
thereby be released from any liability. If Borrower is a corporation, the
agreements contained herein shall remain in full force and applicable
notwithstanding any changes in the shareholders comprising, or the officers and
directors relating to, the corporation, and the term "Borrower" as used herein,
shall include any alternative or successor corporation, but any predecessor
corporation shall not be relieved of liability hereunder. (Nothing in the
foregoing sentence shall be construed as a consent to, or a waiver of, any
prohibition or restriction on transfers of interests in such partnership which
may be set forth in the Loan Agreement, the Mortgage or any other Loan
Document.)

                              ARTICLE 7 - TRANSFER

          Upon the transfer of this Note, Borrower hereby waiving notice of any
such transfer except as provided in the Loan Agreement, Lender may deliver all
the collateral mortgaged, granted, pledged or assigned pursuant to the Loan
Documents, or any part thereof, to the transferee who shall thereupon become
vested with all the rights herein or under applicable law given to Lender with
respect thereto, and Lender shall from that date forward forever be relieved and
fully discharged from any liability or responsibility in the matter; but Lender
shall retain all rights hereby given to it with respect to any liabilities and
the collateral not so transferred.

                             ARTICLE 8 - EXCULPATION

          The provisions of Section 9.4 of the Loan Agreement are hereby
incorporated by reference into this Note to the same extent and with the same
force as if fully set forth herein.

                            ARTICLE 9 - GOVERNING LAW

          THIS NOTE SHALL BE DEEMED TO BE A CONTRACT ENTERED INTO PURSUANT TO
THE LAWS OF THE STATE IN WHICH THE PROPERTY IS LOCATED AND SHALL IN ALL RESPECTS
BE GOVERNED, APPLIED AND

                                        3
<Page>

ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE IN WHICH THE PROPERTY IS
LOCATED AND APPLICABLE FEDERAL LAWS.

                              ARTICLE 10 - NOTICES

          All notices or other written communications hereunder shall be
delivered in accordance with Section 10.6 of the Loan Agreement.
