                  (1) the Lessor shall ground lease the Sites from the Lessee

                  (2) the Lessor shall make Advances (out of funds provided by
            the Participants) to the Construction Agent for the purpose of the
            renovation and construction of Improvements thereon; and

                  (3) the Lessor shall lease the Sites to the Lessee under the
            Master Lease and the Lease Supplement.

Notwithstanding any other provision hereof, the Lessor shall not be obligated to
make any Advance with respect to any Site if, after giving effect thereto, the
aggregate outstanding amounts of the Tranche A Loans, Tranche B Loans and the
Equity Amount allocable to such Site would exceed the Commitments of the Tranche
A Lenders, the Tranche B Lenders and the Certificate Holders, respectively, for
such Site.

            (ii) Subject to the conditions and terms hereof, the Certificate
      Holders shall personally make available at the request of the Lessee from
      time to time during the Construction Period with respect to the Sites, on
      each Funding Date an amount (each an "Equity Amount") in immediately
      available funds equal to the Certificate Holders' Commitment Percentage of
      the amount of the Advance being funded on such Funding Date.
      Notwithstanding any other provision hereof, the Certificate Holders shall
      not be obligated to make available any Equity Amount if, after giving
      effect to the proposed Equity Amount, the outstanding aggregate amount of
      Equity Amounts would exceed the Certificate Holders' Commitment.

      (b) Lenders' Commitment. Subject to the conditions and terms hereof, the
Lenders severally shall make Loans with respect to the Sites to the Lessor at
the request of the Lessee from time to time during the Construction Period, on
each Funding Date in an amount in immediately available funds equal to each such
Lender's Commitment Percentage of the amount of the Advance being funded on such
Funding Date. Notwithstanding any other provision hereof, no Lender shall be
obligated to make any Loan if, after giving effect to the proposed Loan, the
outstanding aggregate amount of such Lender's Loans would exceed such Lender's
Commitment.

                                                       Participation Agreement 4
<PAGE>

time, three (3) Business Days (unless waived) prior to the proposed Funding Date
pursuant to an irrevocable Funding Request substantially in the form of Exhibit
H (a "Funding Request"), specifying: the proposed Funding Date and the amount of
Advance requested. Any Participant may require a duly completed compliance
certificate in substantially the form of Exhibit K as a condition to making an
Advance. With respect to each Funding Request for a Site Acquisition Date, in
addition to the foregoing, the Lessee hereby directs the Lessor to ground lease
the Site and the Lessee shall also specify the Estimated Improvement Costs for
the Site. Each funding shall be in an amount equal to $1,000,000 or an integral
multiple of $100,000 in excess thereof. Lessee shall be allowed a maximum of
three (3) separate LIBO Rate tranches. The proceeds of each funding will be used
to reimburse the Construction Agent for paid Site Costs and to pay accrued and
unpaid interest and Yield and Transaction Expenses; and the Funding Date
therefor shall be a date on or before the applicable Scheduled Payment Date;
provided, however, that if the Lessee fails to duly and timely submit a Funding
Request which provides for the payment of accrued and unpaid interest and Yield
and Transaction Expenses on the applicable Scheduled Payment Date, the Lessee
hereby irrevocably authorizes and directs the Agent (at its option) to cause the
Participants to fund to the Participants such amounts as may be necessary to pay
in full all accrued and unpaid interest and Yield and Transaction Expenses then
due and payable during the Construction Period for such Site and for the one (1)
calendar month thereafter. Fundings for Site Costs (other than interest and
Yield) for any Site shall be made during the Construction Period for such Site.

            (ii) Upon satisfaction or waiver of the conditions precedent to such
Advance set forth in Section 9, in the case of an Advance for the acquisition of
a ground leasehold interest in a Land Interest, the Lessor, as directed by the
Certificate Holders acting at the request of the Lessee, shall pay all Land
Acquisition Costs and pay Transaction Expenses in connection with such
acquisition, and in the case of other Advances, the Lessee, as Construction
Agent, shall pay or retain as payment or reimbursement of Site Costs or
Transaction Expenses the funds provided by the Certificate Holders and the
Lenders for such Advance. The transfer by any Participant of its portion of an
Advance shall evidence such Participant's satisfaction that the conditions
precedent to such Advance have been met or waived. Except as set forth above and
as the parties may otherwise agree in writing, Advances shall be made solely to
provide the Construction Agent with funds with which to pay or reimburse itself
for Site Costs or Transaction Expenses, as the case may be.

            (iii) All remittances made by the Participants for the funding of
any Advance shall be made on the applicable Funding Date in immediately
available Federal funds by wire transfer to the accounts specified in the
applicable Funding Request. Subject to the prior satisfaction of all of the
applicable conditions set forth in Section 9, the Participants will use
reasonable efforts to fund the applicable Advance prior to 1:00 p.m., Chicago
time, on such Funding Date.

            (iv) In no event will (i) the total Property Cost at any time exceed
$93,000,000.00, in the aggregate for the Property under construction or
completed and still subject to the Master Lease, nor (ii) the Site Cost
allocable to the Parking Facility Site exceed $23,000,000.00, nor (iii) the Site
Cost allocable to the Fulton Center Site exceed $70,000,000.00.

      (d) Allocation of Advances. All Advances shall be allocated between the
Sites in accordance with the Funding Request. Advance amounts which do not
specifically relate to any one Site may be allocated and reallocated by the
Lessee from time to time among the Sites in accordance with their respective
Construction Budgets. Amounts due from Lessee, including Supplemental Rent,
shall be allocated to the specific Site to which such amounts relate; provided,
however, that if any amount does not specifically relate to any particular Site,
such amount shall be allocated among the Sites pro rata in accordance with the
Commitment for each of such Sites. Allocations of payments will be made based
upon the source of such payment as described in Section 5(d). Specifically,
without limitation, the Lessee shall maintain a ledger of the allocation of the
following amounts between the Sites from time to time until expiration or
termination of the Master Lease, based upon the Advances allocable to each of
the Sites and allocation of payments under Section 5(d):

      Available Loan Commitments
      Available Equity Commitments
      Basic Rent
      Equity Balance
      Equity Basic Rent
      Equity Amount
      Lease Balance
      Lender Basic Rent
      Loan Balance
      Participant Balance

SECTION 4. YIELD; INTEREST; COMMITMENT FEES.

      (a) Yield.

            (i) The amount of the Equity Amounts outstanding from time to time
shall accrue yield ("Yield") at the Yield Rate, calculated using the actual
number of days elapsed and, when the Yield Rate is determined by reference to
the LIBO Rate (Reserve Adjusted) or the Alternate Base Rate not based upon the
Prime Rate, a 360-day year basis and, when the Yield Rate is determined by
reference to the Alternate Base Rate based upon the Prime Rate, a 365- (or, if
applicable, 366-) day year basis. If all or any portion of the Equity Amounts,
any Yield payable thereon or any other amount payable to any Certificate
Holders, Lessor or Owner Trustee hereunder shall not be paid when due (whether
at stated maturity, acceleration thereof or otherwise), such overdue amount
shall bear interest at a rate per annum which is equal to the Overdue Rate.

            (ii) The Lessee shall, pursuant to the Assignment of Leases and
Rents, deposit in the Account the Equity Basic Rent (determined on the basis of
accrued Yield due in accordance with clause (i) above) and all other amounts due
with respect to the Equity Amounts payable by the Lessee under the Master Lease
from time to time.

            (iii) During the Construction Period for each Site, Yield with
respect to such Site shall accrue on outstanding Equity Amounts and shall be
funded monthly by the Certificate


                                                       Participation Agreement 6
<PAGE>

Holders and the Lenders pursuant to Section 3(a) and (b). During the Basic Term,
such Yield shall be paid as a component of Basic Rent.

      (b) Interest on Loans. (i) The amount of each Loan shall accrue interest
at the applicable rate set forth in the Loan Agreement, calculated using the
actual number of days elapsed and, when the interest on the Loans is determined
by reference to the LIBO Rate (Reserve Adjusted) or the Alternate Base Rate not
based upon the Prime Rate, a 360-day year basis and, when such interest is
determined by reference to the Alternate Base Rate based upon the Prime Rate, a
365- (or, if applicable, 366-) day year basis. If all or any portion of the
Loans, any interest payable thereon or any other amount payable to any Lender,
or the Agent hereunder shall not be paid when due (whether at stated maturity,
acceleration thereof or otherwise), such overdue amount shall bear interest at a
rate per annum which is equal to the Overdue Rate.

            (ii) The Lessee shall, pursuant to the Assignment of Leases and
Rents, deposit in the Account the Lender Basic Rent (determined on the basis of
amounts due in accordance with clause (i) above) and all other amounts due with
respect to the Loans payable by the Lessee under the Master Lease from time to
time.

            (iii) During the Construction Period for each Site interest with
respect to such Site shall accrue on outstanding Loans and shall be funded
monthly by the Certificate Holders and the Lenders pursuant to Section 3(a) and
(b). During the Basic Term, such interest shall be paid as a component of Basic
Rent.

      (c) Prepayments of Loans and Equity Amounts. In the event that the Lessee
pays the Property Balance to the Lessor in connection with the Lessee's purchase
of the Property in accordance with Sections 6, 11 or 16 of the Master Lease, the
Lessor will prepay the entire outstanding principal amount of the Loans and
Equity Amounts. Each of the Lenders and the Lessor hereby acknowledges that its
Loans or Equity Amounts, as the case may be, may be so prepaid without any
prepayment premium other than Break Costs and other amounts pursuant to Section
4(e)(iii).

      (d) Nonuse Fee; Other Fees. The Lessee agrees to pay the fees set forth in
this Section 4(d). During the Construction Period fees may, subject to the
conditions hereof (including without limitation the last sentence of Section
3(a)(i)), be paid or reimbursed with the proceeds of an Advance.

            (i) Nonuse Fee. The Lessee agrees to pay to each Tranche A Lender,
each Tranche B Lender and each Certificate Holder for the Construction Period
(including any portion of such Construction Period when any Participant's
Commitment is suspended by reason of the Lessee's inability to satisfy any
condition of Section 9), a nonuse fee (collectively, the "Nonuse Fee") at a per
annum rate equal to the Applicable Nonuse Fee Percentage on such Participant's
Commitment Percentage of the sum of the Available Commitments. The Nonuse Fee
shall be payable by the Lessee in arrears with respect to each three-month
period (or portion thereof, for the first and last such periods) following the
Documentation Date on the first day of each January, April, July and October
(provided, however, that if such day is not a Business Day, such payment shall
be due on the immediately preceding Business Day in the full amount due on such
first day), commencing July 1, 2000 through and including the first day
immediately following


                                                       Participation Agreement 7
<PAGE>

the expiration of the Construction Period, and shall be determined on the basis
of the daily average Available Commitments during each such three-month period.
The Nonuse Fee shall be computed on the basis of the actual number of days
(including the first day but excluding the last day) occurring during the period
for which such Nonuse Fee is payable over a year of 360 days.

            (ii) Other Fees. The Lessee agrees to pay (w) to the Arranger for
the account of the initial Certificate Holders and Lenders an upfront fee in the
amount set forth in the Fee Letter, payable on the Documentation Date, (x) to
the Agent, for its own account, the Annual Administration Fees, payable on the
Documentation Date and thereafter annually in arrears, (y) to the Arranger, for
its own account, the fees set out in the Fee Letter, and (z) to the Agent, for
the account of the Owner Trustee, the Owner Trustee's Expenses.

      (e) Interest and Yield Protection.

            (i) Alternate Rate of Interest. If prior to the commencement of any
Interest Period for an Advance with interest or Yield determined by reference to
the LIBO Rate (Reserve Adjusted):

                  (1) the Agent determines (which determination shall be
            conclusive absent manifest error) that adequate and reasonable means
            do not exist for ascertaining the Adjusted LIBO Rate or the LIBO
            Rate, as applicable, for such Interest Period; or

                  (2) the Agent is advised by any Participant or Participants
            that because of a change in circumstances affecting the eurocurrency
            market generally the Adjusted LIBO Rate or the LIBO Rate, as
            applicable, for such Interest Period will not adequately and fairly
            reflect the cost to such Participants (or Participant) of making or
            maintaining their Loans or Equity Amounts (or its Loan or Equity
            Amount) for such Interest Period;

then the Agent shall give notice thereof to the Lessee and the Participants by
telephone or telecopy as promptly as practicable thereafter and, until the Agent
notifies the Lessee and the Participants that the circumstances giving rise to
such notice no longer exist, (i) any Funding Request that requests the
conversion or continuation of an Advance with interest determined by reference
to the LIBO Rate (Reserve Adjusted) shall be ineffective, (ii) if any Funding
Request requests an Advance with interest determined by reference to the LIBO
Rate (Reserve Adjusted), such Advance shall be made as an Alternate Base Rate
Advance and (iii) any Funding Request by the Lessee for an Advance with interest
determined by reference to the LIBO Rate (Reserve Adjusted) shall be
ineffective; provided, however, that if the circumstances giving rise to such
notice do not affect all the Participants, then requests by the Lessee for an
Advance with interest determined by reference to the LIBO Rate (Reserve
Adjusted) may be made to Participants that are not affected thereby.

            (ii) Increased Costs.

                  (1) If any Change in Law shall:


                                                       Participation Agreement 8
<PAGE>

                        (a) impose, modify or deem applicable any reserve,
                  special deposit or similar requirement against assets of,
                  deposit with or for the account of, or credit extended by, any
                  Participant (except any such reserve requirement reflected in
                  the Adjusted LIBO Rate); or

                        (b) impose on any Participant or the London interbank
                  market any other condition affecting this Participation
                  Agreement or Advances made by such Participant under this
                  Participation Agreement

            and the result of any of the foregoing shall be to increase the cost
            to such Participant of making, funding or maintaining any such Loan
            or Equity Amount (or of maintaining its obligation to make any such
            Loan or Equity Amount) or to reduce the amount of any sum received
            or receivable by such Participant hereunder (whether of principal,
            interest, Equity Amount, Yield or otherwise), then the Lessee will
            pay to such Participant such additional amount or amounts as will
            compensate such Participant for such additional costs incurred or
            reduction suffered.

                  (2) If any Participant determines that any Change in Law
            regarding capital requirements has or would have the effect of
            reducing the rate of return on such Participant's capital or on the
            capital of such Participant's holding company, if any, as a
            consequence of this Agreement or the Loans or Equity Amounts made,
            funded or created by, such Participant, to a level below that which
            such Participant or such Participant's holding company could have
            achieved but for such Change in Law (taking into consideration such
            Participant's policies and the policies of such Participant's
            holding company with respect to capital adequacy), then from time to
            time the Lessee will pay to such Participant such additional amount
            or amounts as will compensate such Participant or such Participant's
            holding company for any such reduction suffered.

                  (3) A certificate of a Participant setting forth the amount or
            amounts necessary to compensate such Participant or its holding
            company, as the case may be, as specified in paragraph (1) or (2) of
            this Subsection shall be delivered to the Lessee and shall be
            conclusive absent manifest error. The Lessee shall pay such
            Participant the amount shown as due on any such certificate within
            10 days after receipt thereof.

            (iii) Break Funding Payments. In the event of (1) the payment of any
principal of any Loan or Equity Amount other than on the last day of an Interest
Period applicable thereto (including as result of an Event of Default), (2) the
conversion of any Loan or Equity Amount other than on the last day of the
Interest Period applicable thereto, (3) the failure to borrow, convert, continue
or prepay any Loan or Equity Amount on the date specified in any notice
delivered pursuant hereto (regardless of whether such notice is permitted to be
revocable and is revoked in accordance herewith), or (4) the assignment of any
Loan or Equity Amount other than on the last day of the Interest Period
applicable thereto as a result of a request by Lessee then, in any such event,
the Lessee shall compensate each Participant for the loss, costs and expense
attributable to such event, including, without limitation, Break Costs and any
costs associated


                                                       Participation Agreement 9
<PAGE>

with the termination by any Participant of any foreign currency exchange
arrangements. The loss to any Participant attributable to any such event shall
be deemed to include an amount determined by such Participant to be equal to the
excess, if any, of (i) the amount of interest that such Participant would pay
for a deposit equal to the principal amount of such Loan or Equity Amount for
the period from the date of such payment, conversion, failure or assignment to
the last day of the then current Interest Period for such Loan or Equity Amount
(or, in the case of a failure to borrow, convert or continue, the duration of
the Interest Period that would have resulted from such borrowing, conversion or
continuation) if the interest rate payable on such deposit were equal to the
Adjusted LIBO Rate for such Interest Period, over (ii) the amount of interest
that such Participant would earn on such principal amount for such period if
such Participant were to invest such principal amount for such period at the
interest rate that would be bid by such Participant (or an Affiliate of such
Participant) for dollar deposits from other banks in an eurodollar market at the
commencement of such period. A certificate of any Participant setting forth any
amount or amounts that such Participant is entitled to receive pursuant to this
Subsection shall be delivered to the Lessee and shall be conclusive absent
manifest error. The Lessee shall pay such Participant the amount shown as due on
any such certificate within 10 days after receipt thereof.

            (iv) If it becomes illegal for any Participant to continue its
participation in the transaction contemplated by the Operative Documents (the
"Overall Transaction"), the Participant shall give notice promptly to the Agent,
Owner Trustee, each other Participant and the Lessee (including in such notice
reasonable details as to the basis of such illegality). Each Participant agrees
for the benefit of the Lessee and (in the case of a Lender) the Certificate
Holders, if so required by the Lessee, to consult in good faith with the Lessee
and such other parties and to use its reasonable best efforts to avoid such
illegality (including by assigning its rights hereunder and under the other
Operative Documents to an Affiliate or branch of the Participant, and providing
that such Affiliate or branch shall assume its obligations hereunder and
thereunder); provided, however, that such Participant shall not in this
connection be obligated to take any action which would be materially prejudicial
to the operations of the Participant; provided further, however, that the
portion of the Loan or Equity Amount held by such Participant shall be prepaid
on or prior to the date (the "Illegality Prepayment Date") which is the earlier
of the 180th day subsequent to the giving by such Participant of such notice and
the date upon which the Participant is obligated under Applicable Law to
terminate its participation in the Overall Transaction if such illegality has
not been avoided or the portion of the Loan or Equity Amount held by such
Participant has not been prepaid prior to the Illegality Prepayment Date.

      (f) Notice of Yield and Interest. The Agent shall deliver to the Lessee
from time to time written notice of the amount of Basic Rent and the due date
therefor (i) promptly after the commencement of each Interest Period
constituting an Odd LIBOR Period or a one-month LIBOR period, and (ii) promptly
after determination of interest and Yield determined by reference to the
Alternate Base Rate.

      (g) Collateralized Margin. The Lessee shall be entitled to have the
applicable margin for interest accruing on the Property Balance reduced to the
Collateralized Applicable Margin so long as (i) Lessee shall have pledged to the
Agent Eligible Collateral as security for Lessee's obligations under the
Operative Documents, and (ii) such Eligible Collateral shall be


                                                      Participation Agreement 10
<PAGE>

subject to the Pledge Agreement and held by not more than three (3) Securities
Intermediaries (Lessee having a right to change or substitute same) reasonably
acceptable to the Agent pursuant to a Control Agreement. Upon not less than
seven (7) Business Days' notice to the Agent, so long as no Default has occurred
and is continuing, and no Event of Loss, Casualty or Condemnation has occurred,
Lessee may elect to change the composition of the Eligible Collateral and cause
substitute Eligible Collateral to become subject to the Pledge Agreement and
held by a Securities Intermediary pursuant to a Control Agreement. So long as
the minimum Eligible Collateral remains on deposit in the securities accounts
established under the Control Agreements, and so long as no Default has occurred
and is continuing, and no Event of Loss, Casualty or Condemnation has occurred,
the Agent shall permit Lessee to withdraw from such securities account any
accretions (including interest and dividends) to the property held therein.

      The Lessee may elect to switch between the Collateralized Applicable
Margin and the uncollateralized Applicable Margin not more than once in any
Fiscal Quarter. Each determination of an interest rate or yield rate by the
Agent pursuant to any provision of the Operative Documents shall be conclusive
and binding on the Lessor and each Participant in the absence of manifest error.
The Agent shall, at the request of the Lessor, deliver to the Lessor a statement
showing the quotations used by the Agent in determining any interest rate or
yield rate pursuant to the Operative Documents.

SECTION 5. CERTAIN INTENTIONS OF THE PARTIES; DISTRIBUTIONS.

      (a) Nature of Transaction. The parties hereto intend that (1) for
financial accounting purposes with respect to the Lessee, the Lessor will be
treated as the owner or ground lessee and the lessor of the Property, including
the Equipment, and the Lessee will be treated as the lessee of the Property,
including the Equipment, and (2) for all other purposes, including Federal and
all state and local income tax purposes, state real estate law, bankruptcy and
Environmental Law purposes, (x) the Master Lease will be treated as a financing
arrangement, (y) the Participants will be deemed lenders making loans to the
Lessee in an amount equal to the sum of the Equity Amounts and the outstanding
principal amount of the Loans, which loans are secured by the Property, and (z)
the Lessee will be treated as the owner of the Property and will be entitled to
all tax benefits ordinarily available to an owner of property like the Property
for such tax purposes. Nevertheless, the Lessee acknowledges and agrees that
neither the Lessor nor any of the Participants has made any representations or
warranties to the Lessee concerning the tax, accounting or legal characteristics
of the Operative Documents and that the Lessee has obtained and relied upon such
tax, accounting and legal advice concerning the Operative Documents as it deems
appropriate.

            (i) Specifically, without limiting the generality of clause (i), the
parties hereto intend and agree that in the event of any insolvency or
receivership proceedings or a petition under the United States bankruptcy laws
or any other applicable insolvency laws or statute of the United States of
America or any State or Commonwealth thereof affecting the Lessee, the Lessor or
the Participants or any collection actions, the transactions evidenced by the
Operative Documents are loans made to the Lessee by the Participants in each
case as unrelated third party lenders.


                                                      Participation Agreement 11
<PAGE>

      (b) Amounts Due Under Master Lease. Anything else herein or elsewhere to
the contrary notwithstanding, it is the intention of the Lessee, the Certificate
Holders, the Owner Trustee, the Lessor and the Lenders that: (1) the amount and
timing of installments of Basic Rent due and payable from time to time from the
Lessee under the Master Lease shall be equal to the aggregate payments due and
payable as interest on the Loans and Yield on the Equity Amounts on each Payment
Date; (2) if the Lessee becomes obligated or otherwise elects to purchase the
Property under the Master Lease, the Loans, the Equity Amounts, all interest,
Yield and Commitment Fees thereon and all other obligations of the Lessee owing
to the Lessor, the Certificate Holders, the Owner Trustee and the Lenders shall
be paid in full by the Lessee; and if the Lessee becomes obligated to purchase
any Site under Section 11 of the Master Lease, or if the Lessee elects to
purchase any Sites under Section 6(e) of the Master Lease, the applicable
portions of the Loans and the Equity Amounts, all interest, Yield and Commitment
Fees thereon and all other obligations of the Lessee owing to the Lessor, the
Certificate Holders, the Owner Trustee and the Lenders related to such Site or
Sites, as applicable, shall be paid in full by the Lessee in accordance with the
Master Lease; (3) if the Lessee properly elects the Sale Option with respect to
the Property, the Lessee shall only be required to pay to the Certificate
Holders the proceeds of the sale of the Property, the Applicable Percentage
Amount with respect to the Property and any amounts due pursuant to Sections 13
and 14 hereof and Section 6(d) and Section 6(i) of the Master Lease (which
aggregate amounts may be less than the Property Balance), together with any
accrued Basic Rent and Supplemental Rent then due and owing; and (4) upon an
Event of Default resulting in an acceleration of the Lessee's obligation to
purchase the Property under the Master Lease, the amounts then due and payable
by the Lessee under the Master Lease shall include all amounts necessary to pay
in full the Property Balance, plus all other amounts then due from the Lessee to
the Participants under the Operative Documents.

      (c) Agreement to Pay Amounts Due With Respect to Tranche A Loans. In
furtherance of the intent of the parties as set forth in Sections 5(a) and 5(b)
above and as set forth in Section 20(u) of the Master Lease, the Lessee hereby
absolutely, unconditionally and irrevocably (1) agrees to pay in full when due
(after giving effect to any applicable notice and grace period), whether at
stated maturity, by required prepayment, declaration, acceleration, demand or
otherwise, all amounts owing by the Lessor to the Lenders with respect to the
Tranche A Loans and the portion of the Notes evidencing such Tranche A Loans
(including all such amounts which would become due but for the operation of the
automatic stay under Section 362(a) of the United States Bankruptcy Code, 11
U.S.C. ss.362(a), and the operation of Sections 502(b) and 506(b) of the United
States Bankruptcy Code, 11 U.S.C. ss.502(b) and ss.506(b)), and (2) indemnifies
and holds harmless the Lessor, the Agent and each Tranche A Lender for any and
all costs and expenses (including reasonable attorneys' fees) incurred by the
Lessor, the Agent or such Tranche A Lender in enforcing any rights under this
Section 5(c).

      (d) Distribution.

            (i) Subject to Section 5(d)(vii)(4), each payment of Basic Rent (and
any payment of interest on overdue installments of Basic Rent) received by the
Agent shall be distributed by the Agent to the Participants, pro rata in
accordance with, and for application to, the Tranche A Lender Basic Rent,
Tranche B Lender Basic Rent and Equity Basic Rent then due, as well as any
overdue interest due to each such Participant (to the extent permitted by
Applicable Law).

<PAGE>

            (ii) Subject to Section 5(d)(vii)(4), any payment received by the
Lessor or the Agent as a result of:

                  (1) the purchase of the Property in connection with the
            Lessee's exercise of its option under Section 6(e) of the Master
            Lease, or

                  (2) the Lessee's compliance with its obligation to purchase
            (or cause its designee to purchase) the Property in accordance with
            Sections 6(b), 6(e), 6(f) and 6(i) of the Master Lease, or

                  (3) the payment of the Property Balance or portion thereof in
            accordance with Section 6(e) or Section 11 of the Master Lease, and
            any proceeds from any partial prepayments pursuant to Section 6(e)
            of the Master Lease, or

                  (4) the Lessee failing to fulfill one or more of the
            conditions to the exercise of the Sale Option pursuant to Section
            6(d) of the Master Lease and the Lessor's receipt of the Property
            Balance from the Lessee pursuant to Section 6(d)(3) of the Master
            Lease,

shall be promptly remitted by the Lessor to the Agent (if received by the
Lessor) and in each case, shall be distributed by the Agent to pay in full the
Participant Balance of each Participant.

            (iii) The payment by the Lessee of the Applicable Percentage Amount
and all Supplemental Rent due in accordance with Section 6(d)(3) of the Master
Lease upon the Lessee's exercise of the Sale Option and the payment by the
Lessee of the Construction Failure Payment in accordance with Section 6(h) of
the Master Lease shall be promptly remitted by the Lessor (if received by the
Lessor) to the Agent, and shall be distributed by the Agent in the following
amounts and order of priority:

                  first, so much of such payments or amounts as shall constitute
            Supplemental Rent, to the Persons entitled thereto in accordance
            with Section 5(d)(v); and

                  second, to the Tranche A Lenders for application to pay in
            full the Tranche A Loan Balance of each Tranche A Lender, and in the
            case where the amount so distributed shall be insufficient to pay in
            full as aforesaid, then pro rata among the Tranche A Lenders without
            priority of one Tranche A Lender over the other in the proportion
            that each such Participant's Tranche A Loan Balance bears to the
            aggregate Tranche A Loan Balances of all Tranche A Lenders, and

                  third, to the Tranche B Lenders for application to pay in full

            where the amount so distributed shall be insufficient to pay in full
            as aforesaid, then pro rata among the Tranche B Lenders without
            priority of one Tranche B Lender over the other in the proportion
            that each such Participant's Tranche B Loan Balance bears to the
            aggregate Tranche B Loan Balances of all Tranche B Lenders, and


                                                      Participation Agreement 13

            obtained actual knowledge of the attachment of any such Lessor Lien
            for which it is responsible, notify the Lessee and the Certificate
            Holders of the attachment of such Lien and the particulars thereof.
            The term "Owner Trustee Officer" shall mean an officer of the Owner
            Trustee having responsibility for the administration of Wilmington
            Trust Company's and the Owner Trustee's interest in the Operative
            Documents.

                  (2) No Issuance. Wilmington Trust Company agrees that neither
            Wilmington Trust Company nor anyone acting on its behalf has offered
            or will offer any interests in the Trust Estate or any part thereof
            (including the trust certificates) or any securities similar thereto
            for issue or sale to, or has solicited or will solicit any offer to
            acquire any of the same from, anyone so as to bring the issuance and
            sale of the interests in the Trust Estate (including the trust
            certificates) within the provisions of Section 5 of the Securities
            Act or any similar provisions under any applicable state "blue sky"
            or similar state securities laws.

      (c) Owner Trustee and Trust Representations and Warranties. The Owner
Trustee and the Trust hereby represent and warrant on the date hereof that:

                  (1) Due Organization. Assuming the due authorization,
            execution and delivery of the Trust Agreement by the Certificate
            Holders, the Owner Trustee has the power and authority under the
            Trust Agreement to enter into and perform its obligations under each
            Operative Document to which the Owner Trustee is or will become a
            party

                  (2) Due Authorization; Enforceability. Assuming due
            authorization, execution and delivery of the Trust Agreement by the
            Participants and Wilmington Trust Company, each Operative Document
            (other than the Trust Agreement) to which the Trust or the Owner
            Trustee is or will become a party constitutes or will constitute
            upon the due execution thereof a legal, valid and binding obligation
            of the Owner Trustee and the Trust, enforceable against the Owner
            Trustee and the Trust, in accordance with its terms, except as
            enforceability thereof may be limited by (i) bankruptcy, insolvency,
            reorganization, moratorium or other similar laws affecting
            enforcement of creditors' rights generally and (ii) general
            principles of equity (regardless of whether such enforceability is
            considered in a proceeding in equity or at law).

<PAGE>

                  (3) No Liens. On each Site Acquisition Date, the Sites to be
            leased on such Site Acquisition Date shall be free and clear of
            Lessor Liens arising by, through or under the Owner Trustee (other
            than Permitted Liens).

                  (4) Chief Executive Office. The principal place of business
            and chief executive office (as such term is used in Article 9 of the
            Uniform Commercial Code) of Owner Trustee and the Trust is located
            at Rodney Square North, 1100 North Market Street, Wilmington,
            Delaware 19890.

                  (5) Due Organization. The Trust has been duly formed and is
            validly existing and in good standing as a statutory business trust
            under the laws of the State of Delaware, and has the power and
            authority to enter into and perform its obligations under each of
            the Operative Documents, including this Participation Agreement, the
            Master Lease and the Lease Supplements to which it is or is to
            become a party.

                  (6) Assignment. It has not assigned or transferred any of its
            right, title or interest in or under the Master Lease or the
            Construction Agency Agreement except in accordance with the
            Operative Documents.

                  (7) Use of Proceeds. The proceeds of the Loans and the Equity
            Amounts shall be applied by the Trust in its capacity as the Lessor
            solely in accordance with the provisions of the Operative Documents.

                  (8) Securities Act. Neither the Trust in its capacity as the
            Lessor nor any Person authorized by the Trust to act on its behalf
            has offered or sold any interest in the Notes or Equity Amounts, or
            in any similar security relating to the Sites, or in any security
            the offering of which for the purposes of the Securities Act would
            be deemed to be part of the same offering as the offering of the
            aforementioned securities to, or solicited any offer to acquire any
            of the same from, any Person other than, in the case of the Notes,
            the Lenders, and neither the Trust in its capacity as the Lessor nor
            any Person authorized by the Trust to act on its behalf will take
            any action which would subject the issuance or sale of any interest
            in the Notes or Equity Amounts to the provisions of Section 5 of the
            Securities Act.

                  (9) Federal Reserve Regulations. The Trust is not engaged
            principally in, and does not have as one of its important
            activities, the business of extending credit for the purpose of
            purchasing or carrying any margin stock (within the meaning of
            Regulation U of the F.R.S. Board), and no part of the proceeds of
            the Loans or the Equity Amounts will be used by it to purchase or
            carry any margin stock or to extend credit to others for the purpose
            of purchasing or carrying any such margin stock or for any purpose
            that violates, or is inconsistent with, the provisions of Regulation
            T, U or X of the F.R.S. Board. Terms for which meanings are provided
            in F.R.S. Board Regulation T, U or X or any regulations substituted
            therefor, as from time to time in effect, are used in this clause
            (9) with such meanings.


                                                      Participation Agreement 22
<PAGE>

                  (10) Investment Company Act. The Trust is not an "investment
            company" or a company controlled by an "investment company" within
            the meaning of the Investment Company Act of 1940, as amended.

      (d) Owner Trustee and Trust Agreements. Owner Trustee and the Trust agree
that:

                  (1) Lessor Liens. The Owner Trustee and the Trust will not
            directly or indirectly create, incur, assume or suffer to exist any
            Lessor Liens arising by, through or under it on the Trust Estate.
            The Owner Trustee shall, at the cost and expense of the Trust
            Estate, promptly take such action as may be necessary to discharge
            duly all Lessor Liens attributable to it on any part of the Trust
            Estate, other than Lessor Liens being contested by a Permitted
            Contest. The Owner Trustee shall make restitution to the Trust
            Estate for any diminution in the value of the Trust Estate as a
            result of its failure to discharge any Lessor Liens attributable to
            it.

                  (2) Notices. In the event any claim with respect to any
            liabilities is filed against the Owner Trustee or the Trust, the
            Owner Trustee shall promptly notify the Certificate Holders and the
            Lessee thereof.

                  (3) Title. On the Documentation Date and each Site Acquisition
            Date the Trust will take whatever interest in the Trust Estate and
            whatever rights to and interests in the Master Lease and the Lease
            Supplements as were granted or conveyed to it, free and clear of any
            Lessor Liens attributable to it.

                  (4) Business of Owner Trustee and Trust. The business of the
            Owner Trustee and the Trust is and will continue to be restricted
            (until the expiration or earlier termination of the Master Lease
            with respect to a Site) to the holding of the Sites and the leasing
            of such pursuant to the Operative Documents and it will not engage,
            and it has not engaged, in any other business transaction except for
            administration of the Trust Estate (including any assignment for
            security of the Master Lease and any Sites) and for matters
            reasonably incidental to any of the foregoing.

                  (5) Trust Agreement. The Owner Trustee agrees that (unless a
            Lease Event of Default shall have occurred and be continuing) until
            expiration or earlier termination of the Master Lease, it will not
            terminate the Trust Agreement without the prior written consent of
            the Lessee.

SECTION 8. REPRESENTATIONS, WARRANTIES AND AGREEMENTS OF LESSEE, CONSTRUCTION
           AGENT AND GUARANTOR.

      (a) General Representations and Warranties. The Lessee hereby represents
and warrants to each of the other parties hereto that:

                  (1) Due Organization. The Lessee and each of its Subsidiaries
            (i) is a corporation or other entity duly organized and validly
            existing in good standing


                                                      Participation Agreement 23
<PAGE>

            under the laws of the jurisdiction of its organization, (ii) has all
            requisite corporate or other power and authority and legal right to
            own, hold under lease and operate its properties and to carry on its
            business as now conducted and as presently proposed to be conducted
            and to enter into, and perform its obligations under, each of the
            Operative Documents to which it is or will become a party, and (iii)
            has duly qualified and is authorized to do business and is in good
            standing as a foreign corporation in the State of Illinois (in the
            case of the Lessee) and in each jurisdiction in which its business
            is conducted.

                  (2) Due Authorization; Enforceability. Each of the Operative
            Documents to which it is or will become a party has been or will be,
            when executed and delivered, duly authorized by all appropriate
            corporate action, and has been or will be executed and delivered by
            the Lessee and, assuming due authorization, execution and delivery
            by the other parties thereto, constitutes or will constitute upon
            the due execution thereof the Lessee's legal, valid and binding
            obligation, enforceable against it in accordance with its terms,
            except as enforceability thereof may be limited by (i) bankruptcy,
            insolvency, reorganization, moratorium or other similar laws
            affecting enforcement of creditors' rights generally and (ii)
            general principles of equity (regardless of whether such
            enforceability is considered in a proceeding in equity or at law).

                  (3) No Violation. The execution and delivery by the Lessee of
            each of the Operative Documents to which it is or will become a
            party are not, and the performance by the Lessee of its obligations
            under each will not be, inconsistent with its Organic Documents, do
            not and will not contravene any Applicable Law in any material
            respect and do not and will not contravene any provision of, or
            constitute a default under, any indenture, mortgage or other
            material contract or other instrument to which the Lessee is a party
            or by which it or its property is bound or require the consent or
            approval of, the giving of notice to, the registration with or the
            taking of any action in respect of or by, any Governmental Authority
            or other Person, except such as have been obtained, given or
            accomplished.

                  (4) Governmental Actions. The Lessee has made or will make all
            filings, recordings and registrations required by any Governmental
            Authority in connection with, and has obtained or will obtain, all
            Governmental Actions necessary or appropriate for the performance by
            the Lessee of the transactions contemplated hereby and by the other
            Operative Documents which are then or theretofore required by
            Applicable Law; the Lessee will make all filings, recordings and
            registrations required by any Governmental Authority in connection
            with, and will obtain, all material Governmental Actions necessary
            or appropriate for the performance by the Lessee of the transactions
            contemplated hereby and by the other Operative Documents not later
            than the dates required by Applicable Law.

                  (5) No Litigation. There is no litigation, arbitration,
            governmental investigation, proceeding or inquiry pending or, to the
            knowledge of any of their


                                                      Participation Agreement 24
<PAGE>

            officers, threatened against or affecting the Lessee or any of its
            Subsidiaries which could reasonably be expected to have a Material
            Adverse Effect or which seeks to prevent, enjoin or delay the making
            of any Funding hereunder. Other than any liability incident to any
            litigation, arbitration or proceeding which could not reasonably be
            expected to have a Material Adverse Effect, the Lessee has no
            material contingent obligations not provided for or disclosed in the
            financial statements referred to in Section 8(a)(18).

                  (6) Performance. Neither the Lessee nor any Subsidiary is in
            violation of any Applicable Law the violation of which is reasonably
            likely materially and adversely to affect the transactions
            contemplated by this Participation Agreement and the other Operative
            Documents or which would materially adversely affect Lessee's
            ability to perform its obligations under each of the Operative
            Documents or which otherwise could reasonably be expected to have a
            Material Adverse Effect.

                  (7) No Adverse Contracts or Applicable Law. Neither the Lessee
            nor any Subsidiary is a party to, or bound by, any contract or
            agreement or instrument, or subject to any charter or other
            corporate restriction or any Applicable Laws which materially and
            adversely affects the transactions contemplated by this
            Participation Agreement or the Operative Documents or which would
            materially adversely affect its ability to perform its obligations
            under each of the Operative Documents. Neither the Lessee nor any
            Subsidiary is in default in the performance, observance or
            fulfillment of any of the obligations, covenants or conditions
            contained in any agreement to which it is a party, which default
            could reasonably be expected to have a Material Adverse Effect. No
            obligation (including any guarantee or other contingent obligation)
            of the Lessee or of any Subsidiary or Affiliate of Lessee in respect
            of any Material Indebtedness now or hereafter outstanding is or has
            become due by its terms whether by acceleration or otherwise and has
            not been paid, extended or refunded.

                  (8) Taxes. The Lessee and its Subsidiaries have filed all
            United States federal income tax returns and all other material tax
            returns which are required to be filed and have paid all taxes due
            pursuant to said returns or pursuant to any assessment received by
            the Lessee or any of its Subsidiaries, 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. The United States income
            tax returns of the Lessee and its Subsidiaries have been audited by
            the Internal Revenue Service through the fiscal year ended December
            31, 1996. No tax liens have been filed and no claims are being
            asserted with respect to any such taxes as of the Documentation Date
            except as set forth in Schedule 8(a)(8). The charges, accruals and
            reserves on the books of the Lessee and its Subsidiaries in respect
            of any taxes or other governmental charges are adequate.


                                                      Participation Agreement 25
<PAGE>

                  (9) Investment Company Act. The Lessee is not an "investment
            company" or a company "controlled" by an "investment company",
            within the meaning of the Investment Company Act of 1940, as
            amended.

                  (10) Disclosure. Neither the financial statements referred to
            in Section 8(a)(18) nor any written statement furnished by or on
            behalf of Lessee in connection with the negotiation of the Master
            Lease or any other Operative Document contains any untrue statement
            of a material fact or omits a material fact necessary to make the
            statements contained therein or herein not misleading. There is no
            fact known to Lessee that has not been disclosed in writing to the
            other parties hereto that materially and adversely affects the
            ability of Lessee to perform its obligations under the Operative
            Documents.

                  (11) Holding Company. Lessee is not subject to regulation as a
            "holding company", an "affiliate" of a "holding company" or a
            "subsidiary company" of a "holding company", within the meaning of
            the Public Utility Holding Company Act of 1935, as amended.

                  (12) Prohibited Transactions. The execution and delivery by
            the Lessee of the Operative Documents to which it is or will become
            a party, will not involve any prohibited transaction within the
            meaning of ERISA or Section 4975 of the Code. The representation by
            the Lessee in this paragraph is made in reliance upon and subject to
            the accuracy of the representations of the Participants in Section
            6(a)(vi) hereof as to the source of funds for the Participant's
            Loans or Equity Amounts, as applicable.

                  (13) Patents and Trademarks. The Lessee owns or possesses or
            has the right to use all the patents, patent rights, trademarks,
            service marks, trade names, copyrights, licenses and similar rights
            necessary for the performance of its obligations under the Operative
            Documents, without any conflict known to it with the actual or
            asserted rights of others which materially and adversely affect the
            Lessee's ability to perform its obligations under the Operative
            Documents to which it is or will become a party. It is understood
            and agreed by the parties hereto that no interest in any trademark,
            trade name, copyright or service mark of the Lessee or an Affiliate
            thereof is being conveyed or transferred to the Owner Trustee or any
            other Person pursuant to any Operative Document.

                  (14) Regulatory Jurisdiction. None of the Participants or
            Owner Trustee or Wilmington Trust Company will become, (i) solely by
            reason of entering into this Participation Agreement or the other
            Operative Documents or (except with respect to the exercise by any
            Person of any control over a Site upon the occurrence of a Lease
            Event of Default or the expiration or other termination of the
            Master Lease) the consummation of any of the transactions
            contemplated hereby or thereby, subject to regulation by any
            Governmental Authority which regulates or otherwise has jurisdiction
            over any facilities for the retail distribution of petroleum
            products; or (ii) except for regulation the applicability of which
            depends on the existence of facts in addition to the ownership of
            the Sites upon


                                                      Participation Agreement 26
<PAGE>

            the exercise of remedies under the Master Lease or upon the
            expiration of the Master Lease, subject to ongoing regulation of its
            operations by any Governmental Authority.

                  (15) Private Offering. Neither the Lessee nor any Person
            authorized to act on Lessee's behalf has offered, either directly or
            indirectly, the Notes or any interest in the Trust Estate (including
            the trust certificates) for sale to, or solicited offers to buy any
            thereof from or otherwise approached or negotiated with respect
            thereto with any prospective purchaser, other than the Participants.
            The Lessee has not authorized or employed any Person to act as
            agent, broker, finder, financial advisor or otherwise in connection
            with the offering of interests in the Notes or the Trust Estate
            (including the trust certificates).

                  (16) No Defaults. No Lease Default or Lease Event of Default
            has occurred and is continuing.

                  (17) Fees. Neither the Lessee nor any Person authorized or
            employed by the Lessee as agent or otherwise has taken any action
            the effect of which would be to cause the Certificate Holders, the
            Trust Estate, or the Owner Trustee to be liable for any brokers',
            finders', agents', or advisors' fees or commissions or costs of any
            nature or kind claimed by or on behalf of brokers, finders, agents
            or advisors in respect of the transactions contemplated by the
            Operative Documents.

                  (18) Financial Statements; No Material Adverse Change. The
            September 30, 1999 consolidated financial statements of the Lessee
            and its Subsidiaries heretofore delivered to the Participants were
            prepared in accordance with generally accepted accounting principles
            in effect on the date such statements were prepared and fairly
            present the consolidated financial condition and operations of the
            Lessee and its Subsidiaries at such date and the consolidated of
            their operations for the period then ended.

                       Since the period ending September 30, 1999, there has
            been no change in the business, property, condition (financial or
            otherwise) or results of operations of the Lessee and its
            Subsidiaries which could reasonably be expected to have a Material
            Adverse Effect.

                  (19) Chief Executive Office. The principal place of business
            and chief executive office (as such term is used in Article 9 of the
            Uniform Commercial Code) of Lessee is located at 311 South Wacker
            Drive, Chicago, Illinois 60606.

                  (20) Use of Loans and Proceeds. No part of any Advance will be
            used directly or indirectly for the purpose of purchasing or
            carrying, or for payment in full or in part of indebtedness that was
            incurred for the purposes of purchasing or carrying, any margin
            stock as such term is defined in Regulation U of the F.R.S. Board.


                                                      Participation Agreement 27
<PAGE>

                  (21) Regulations T, U and X. No proceeds of any of the
            Advances will be used for a purpose which violates, or would be
            inconsistent with, F.R.S. Board Regulation T, U or X. Terms for
            which meanings are provided in F.R.S. Board Regulation T, U or X or
            any regulations substituted therefor, as from time to time in
            effect, are used in clauses (20) and (21) with such meanings. Margin
            stock (as defined in Regulation U) constitutes less than 25% of the
            value of those assets of the Lessee and its Subsidiaries which are
            subject to any limitation on sale, pledge, or other restriction
            hereunder.

                  (22) Subsidiaries. Schedule 8(a)(22) contains an accurate list
            of all Subsidiaries of the Lessee as of the date of this Agreement,
            setting forth their respective jurisdictions of organization and the
            percentage of their respective capital stock or other ownership
            interests owned by the Lessee or other Subsidiaries. All of the
            issued and outstanding shares of capital stock or other ownership
            interests of such Subsidiaries have been (to the extent such
            concepts are relevant with respect to such ownership interests) duly
            authorized and issued and are fully paid and nonassessable.

                  (23) ERISA. The Lessee 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). The Unfunded Liabilities of all Single
            Employer Plans do not in the aggregate exceed $5,000,000. Each Plan
            complies in all material respects with all Applicable Law, no
            Reportable Event has occurred with respect to any Plan, neither the
            Lessee nor any other member of the Controlled Group has withdrawn
            from any Plan or initiated steps to do so, and no steps have been
            taken to reorganize or terminate any Plan.

                  (24) Except as set forth on Schedule 8(a)(24), on the date of
            this Participation Agreement, the Lessee and its Subsidiaries will
            have good title, free of all Liens other than those permitted by
            Section 8(d)(19), to all of the property and assets reflected in the
            Lessee's most recent consolidated financial statements provided to
            the Agent as owned by the Lessee and is Subsidiaries.

                  (25) In the ordinary course of its business, the officers of
            the Lessee consider the effect of Environmental Laws on the business
            of the Lessee and its Subsidiaries, in the course of which they
            identify and evaluate potential risks and liabilities accruing to
            the Lessee due to Environmental Laws. On the basis of this
            consideration, the Lessee has concluded that Environmental Laws
            cannot reasonably be expected to have a Material Adverse Effect.
            Neither the Lessee nor any Subsidiary has received any notice to the
            effect that its operations are not in material compliance with any
            of the requirements of applicable 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.

      (b) Site Acquisition Date Representations and Warranties. As of each Site
Acquisition Date, the Lessee hereby represents and warrants to each of the other
parties hereto that:

                  (1) Representations and Warranties. The representations and
            warranties of the Lessee in the Operative Documents and in Section
            8(a) hereof are true and accurate on and as of such Site Acquisition
            Date, as though made on and as of such Site Acquisition Date (or, if
            stated to relate to an earlier date, shall have been true and
            accurate as of such earlier date). No Event of Default has occurred
            and is continuing and no Default of which the Lessee has knowledge
            and that has not been previously disclosed to the Participants has
            occurred and is continuing under the Master Lease or the
            Construction Agency Agreement or, to the knowledge of the Lessee,
            any other Operative Document. No Default or Event of Default under
            the Master Lease or the Construction Agency Agreement or, to the
            knowledge of the Lessee, any other Operative Document, will occur as
            a result of, or after giving effect to, the acquisition of the Land
            Interest on such date.

                  (2) Due Authorization; Enforceability. Each of the Operative
            Documents to which it is or will become a party with respect to such
            Site Acquisition Date has been or will be, when executed and
            delivered, duly authorized by all appropriate corporate action, and
            has been or will be executed and delivered by the Lessee and,
            assuming due authorization, execution and delivery by the other
            parties thereto, constitutes or will constitute upon the due
            execution thereof the Lessee's legal, valid and binding obligation,
            enforceable against it in accordance with its terms, except as
            enforceability thereof may be limited by (i) bankruptcy, insolvency,
            reorganization, moratorium or other similar laws affecting
            enforcement of creditors' rights generally and (ii) general
            principles of equity (regardless of whether such enforceability is
            considered in a proceeding in equity or at law).

                  (3) No Violation. The execution and delivery by the Lessee of
            each of the Operative Documents to which it is or will become a
            party with respect to such Site Acquisition Date are not, and the
            performance by the Lessee of its obligations under each will not be,
            inconsistent with its Organic Documents, do not and will not
            contravene any Applicable Law, and do not and will not contravene
            any provision of, or constitute a default under, any indenture,
            mortgage or other material contract or other instrument to which the
            Lessee is a party or by which it or its property is bound or require
            the consent or approval of, the giving of notice to, the
            registration with or the taking of any action in respect of or by,
            any Governmental Authority or other Person, except such as have been
            obtained, given or accomplished.

                  (4) Governmental Actions. The Lessee has made or will make all
            filings, recordings and registrations required by any Governmental
            Authority in connection with, and has obtained or will obtain, all
            Governmental Actions necessary or appropriate for the construction
            and commercial operation and use of the applicable Site and the
            performance by the Lessee of the transactions


                                                      Participation Agreement 29
<PAGE>

            contemplated hereby and by the other Operative Documents which are
            then or theretofore required by Applicable Law; the Lessee will make
            all filings, recordings and registrations required by any
            Governmental Authority in connection with, and will obtain, all
            material Governmental Actions necessary or appropriate for the
            construction and commercial operation and use of the applicable Site
            and the performance by the Lessee of the transactions contemplated
            hereby and by the other Operative Documents not later than the dates
            required by Applicable Law.

                  (5) No Litigation. There are no pending or, to the best
            knowledge of the Lessee, threatened actions or proceedings by or
            before any court or administrative agency or other Governmental
            Authority to which the Lessee is or may become a party or the
            applicable Site is or may become subject which (i) involves any of
            the transactions contemplated hereunder or by any of the Operative
            Documents or (ii) if determined adversely to it, would reasonably be
            likely to materially adversely affect the Lessee's ability to
            perform its obligations under each of the Operative Documents to
            which the Lessee is or will become a party.

                  (6) Performance. Neither the Lessee nor the applicable Site is
            in violation of any Applicable Law the violation of which is
            reasonably likely materially and adversely to affect such Site or
            the transactions contemplated by this Participation Agreement and
            the other Operative Documents or which would materially adversely
            affect Lessee's ability to perform its obligations under each of the
            Operative Documents.

                  (7) No Adverse Contracts or Applicable Law. The Lessee is not
            a party to, or bound by, any contract or agreement or instrument, or
            subject to any charter or other corporate restriction or any
            Applicable Laws which materially and adversely affects the
            applicable Site or the transactions contemplated by this
            Participation Agreement or the Operative Documents or which would
            materially adversely affect its ability to perform its obligations
            under each of the Operative Documents.

                  (8) Patents and Trademarks. The Lessee owns or possesses or
            has the right to use all the patents, patent rights, trademarks,
            service marks, trade names, copyrights, licenses and similar rights
            necessary for the use and operation of the applicable Site under the
            Operative Documents, without any conflict known to it with the
            actual or asserted rights of others which materially and adversely
            affect the Lessee's ability to perform its obligations under the
            Operative Documents to which it is or will become a party. It is
            understood and agreed by the parties hereto that no interest in any
            trademark, trade name, copyright or service mark of the Lessee or an
            Affiliate thereof is being conveyed or transferred to the Owner
            Trustee or any other Person pursuant to any Operative Document.

      (c) Funding Date Representations and Warranties. As of each Funding Date
and each applicable Site Acquisition Date, on which an Advance is made and with
respect to each Site, the Lessee represents and warrants that:


                                                      Participation Agreement 30
<PAGE>

                  (1) Representations and Warranties. The representations and
            warranties of the Lessee in the Operative Documents and in Section
            8(a) and Section 8(b) hereof are true and accurate on and as of such
            Funding Date, as though made on and as of such Funding Date (or, if
            stated to relate to an earlier date, shall have been true and
            accurate as of such earlier date). No Event of Default has occurred
            and is continuing and no Default of which the Lessee has knowledge
            and that has not been previously disclosed to the Participants has
            occurred and is continuing under the Master Lease or the
            Construction Agency Agreement or, to the knowledge of the Lessee,
            any other Operative Document. No Default or Event of Default under
            the Master Lease or the Construction Agency Agreement or, to the
            knowledge of the Lessee, any other Operative Document, will occur as
            a result of, or after giving effect to, the Advance requested by the
            Funding Request on such date.

                  (2) Enforceability. The related Lease Supplement has been duly
            executed and delivered by the Lessee, and, assuming due
            authorization, execution and delivery thereof by the Lessor,
            constitutes the Lessee's legal, valid and binding obligation,
            enforceable against Lessee in accordance with its terms, except as
            enforceability thereof may be limited by (i) bankruptcy, insolvency,
            reorganization, moratorium or other similar laws affecting
            enforcement of creditors' rights generally and (ii) general
            principles of equity (regardless of whether such enforceability is
            considered in a proceeding in equity or at law).

                  (3) No Support Agreements. The ownership and use of such Site
            by the Trust, the Owner Trustee or the Certificate Holders does not
            require the execution by, or assignment to, any such party of any
            easement, utility, maintenance or other support agreements.

                  (4) Applicable Laws. Such Site and the commercial operation
            thereof for its intended purposes and use thereof are and will be in
            compliance with all Applicable Laws, including, without limitation,
            zoning, planning, building, occupational safety and health laws and
            Environmental Laws of any Governmental Authority having jurisdiction
            over such Site, the Trust, the Owner Trustee, the Lessor or the
            Lessee and all Permitted Exceptions affecting such Site, other than
            such non-compliance that would not, individually or in the
            aggregate, (i) have a Material Adverse Effect, or (ii) impose any
            material penalty on, or result in the imposition of any criminal
            liability on, any Indemnified Person. All requirements thereof
            necessary for the use, occupancy and operation of such Site which
            are then or theretofore required by Applicable Laws or applicable
            Permitted Exceptions have been satisfied in all material respects.

                  (5) No Taxes. No sales, use, transfer, documentation, real
            estate or similar taxes, fees or other charges are payable on the
            Site Acquisition Date for each Site under the laws of any State or
            any governmental subdivision thereof in which a Site is located in
            connection with (A) the entering into, or performance under, or
            enforcement of any Operative Document with respect thereto or (B)
            the lease to the Lessee of the Sites, except such taxes, fees and
            other charges as have been


                                                      Participation Agreement 31
<PAGE>

            paid or will be paid by the Lessee when due or are included in
            Property Cost or Transaction Expenses.

                  (6) No Events of Loss. Except as disclosed in writing to the
            Certificate Holders in accordance with the Operative Documents, no
            Event of Loss with respect to the Property has occurred and no event
            or condition has occurred which would, with the passage of time or
            the giving of notice, or both, constitute an Event of Loss with
            respect to the Property.

                  (7) Advance. The amount of the Advance requested represents
            amounts owed by the Lessee or Construction Agent in respect of Land
            Acquisition Costs, Property Improvement Costs or Transaction
            Expenses, as the case may be, incurred prior to the date of such
            Advance and for which the Lessee has not previously been reimbursed
            by an Advance or represent amounts with respect to Commitment Fees.
            The conditions precedent to such Advance and the related Equity
            Amount and Loans set forth in Section 9 have been satisfied or
            waived by the Participants.

                  (8) Site. The Site has vehicular and pedestrian access to and
            from open, publicly dedicated streets. The Site has available
            through publicly available right-of-ways or valid easements from
            third parties all services of public utilities necessary for use and
            operation of the Site for its current use. The Site is free from
            material physical defects. No fire or other casualty has occurred
            which has had a Material Adverse Effect on the Site and with respect
            to which the Site has not been repaired or restored.

                  (9) Sites Complete, Description of and Title to Sites. On the
            Site Acquisition Date for each Site, all material approvals of any
            Governmental Authority necessary for the commercial operation of
            such Site will have been received and be in full force and effect.
            On each Site Acquisition Date, after giving effect to the
            transactions contemplated hereby, the Trust will have good and
            marketable title to the Improvements and a ground leasehold interest
            in each Land Interest related to such Site Acquisition Date, subject
            to no Title Defects, free and clear of all Liens, except Permitted
            Liens. As of the date of execution thereof, the description set
            forth in each Lease Supplement will be a true, complete and accurate
            description of the property leased thereunder; and each Site shall
            be located wholly within the boundaries of its respective property,
            without any encroachments onto or therefrom.

                  (10) Compliance With Environmental Protection Requirements. On
            the Site Acquisition Date for each Site (except as disclosed in the
            Environmental Audits delivered by Lessee to the Certificate Holders,
            Lessor and the Lenders for each Site) and during the Lease Term,
            each and every Site is in compliance in all material respects with
            all Environmental Laws which are applicable to the Sites including,
            without limitation, Environmental Laws pertaining to design and
            performance standards and quality criteria for air, water and
            reclamation, and the use, storage, disposal and transportation of
            Hazardous Substances.

<PAGE>

                  (11) Information Provided to Appraiser. With respect to each
            Site, all information and materials which have been provided by the
            Lessee to the Appraiser of such Site in connection with the
            Appraisal of such Site are true and accurate in all material
            respects on the date as of which such information and materials are
            dated or certified and are not incomplete by omitting to state any
            fact necessary to make such information (taken as a whole) not
            misleading at such time in light of the circumstances under which
            such information was provided.

                  (12) Environmental Laws. Except as described in the
            Environmental Audit delivered by the Lessee to the Certificate
            Holders, the Lessor and the Lenders, to the best of the Lessee's
            knowledge:

                        (i) there are no pending or threatened claims,
                  complaints, notices or requests for information relating to
                  the Sites received by the Lessee with respect to any alleged
                  violation of any Environmental Law, which may reasonably be
                  expected to have a Material Adverse Effect on the financial
                  condition, operations, assets, business or properties of the
                  Lessee or which may reasonably be expected to have a Material
                  Adverse Effect on the Site, and

                        (ii) there are no pending or threatened complaints,

            area by the Federal Emergency Management Agency or other applicable
            agency. If any of the Sites is located in an area identified as a
            special flood hazard area by the Federal Emergency Management Agency

SECTION 10. COMPLETION DATE CONDITIONS.

      (a) Completion Date. The Completion Date with respect to each Site shall
be deemed to have occurred for purposes of the Operative Documents on the
earlier of:

                  (1) the earliest date on which each of the following events
            shall have occurred:

                        (a) the Construction relating to such Site shall have
                  been substantially completed in accordance with the Plans and
                  Specifications and all Applicable Law;

                        (b) such Site shall be ready for occupancy and operation
                  for its intended purpose in accordance with the Plans and
                  Specifications, as evidenced by the issuance by the
                  appropriate Governmental Authority of temporary and/or
                  permanent certificates of occupancy for all of the
                  Improvements (other than such Improvements that are not
                  essential to the operation of such Site for its intended
                  purpose in accordance with the Plans and Specifications)
                  contemplated by the Plans and Specifications; and

                        (c) the Lessor and the Agent shall have received a
                  Completion Certificate from the Construction Agent
                  substantially in the form of Exhibit F hereto (a "Completion
                  Certificate"), or

                  (2) the Outside Completion Date.

      (b) Reappraisal Upon Completion. Within ten (10) days from the Completion
Date for any Site, the Participants shall be entitled to require, at Lessee's
sole cost and expense, a new Appraisal of such Site taking into account such
Completion. Such new Appraisal shall use methodology similar to that of the
Appraisal delivered in connection with the applicable Site Acquisition Date,
with appropriate changes in assumptions. In the event such new Appraisal shall
conclude that the Fair Market Sales Value of such Site upon such Completion or
as of the end of the Basic Term, and as may be extended pursuant to Section 6(a)
of the Master Lease, is less than the Site Balance (such amount, a "FMV
Shortfall"), Lessee shall make a special lease payment to the Agent equal to
such FMV Shortfall. Notwithstanding the foregoing, Lessee may elect, at Lessee's
cost, to deliver to the Participants, the Agent and the Owner Trustee, not later
than sixty (60) days prior to the Completion Date, a residual value insurance
policy in amount, form and substance acceptable to each of the Participants, the
Agent and the Owner Trustee from


                                                      Participation Agreement 48

an insurance company acceptable to the Participants, the Agent and the Owner
Trustee, which will insure any loss from the value of the applicable Site being
less than the applicable Site Balance. In such event, the Participants shall not
request a new Appraisal.

SECTION 11. TRANSFERS OF LENDERS' INTERESTS.

      (a) Permitted Assignments. Any Lender may, in the ordinary course of its
business and in accordance with Applicable Law, at any time assign to one or
more banks or other entities ("Transferees") all or any part of its rights and
obligations under the Operative Documents or the Property subject to the consent
of Lessee, which consent shall not be unreasonably withheld. Such assignment
shall be substantially in the form of Exhibit J-1 or in such other form as may
be agreed to by the parties thereto. The consent of the Lessee and the Agent
shall be required prior to an assignment becoming effective with respect to a
Transferee which is not a Lender or an Affiliate thereof; provided, however,
that if an Event of Default has occurred and is continuing, the consent of the
Lessee shall not be required. Such consent shall not be unreasonably withheld or
delayed. Each such assignment with respect to a Transferee which is not a Lender
or an Affiliate thereof shall (unless each of the Lessee and the Agent otherwise
consents) be in an amount not less than the lesser of (i) $5,000,000.00 or (ii)
the remaining amount of the assigning Lender's Commitment (calculated as at the
date of such assignment) or outstanding Loans (if the applicable Commitment has
been terminated).

      (b) Effect; Effective Date. Upon (i) delivery to the Agent of an
assignment, together with any consents required by Section 11(a), and (ii)
payment of a $4,000 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 Transferee 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 Transferee in and under the Operative Documents
or the Property will not be "plan assets" under ERISA. On and after the
effective date of such assignment, such Transferee shall for all purposes be a
Lender party to this Agreement and any other Operative Document executed by or
on behalf of the Lenders and shall have all the rights and obligations of a
Lender under the Operative Documents, to the same extent as if it were an
original party hereto, and no further consent or action by the Lessee, the
Lenders or the Agent shall be required to release the transferor Lender with
respect to the percentage of the aggregate Commitments and Loans assigned to
such Transferee. Upon the consummation of any assignment to a Transferee
pursuant to this Section 11(b), the transferor Lender, the Agent and the Lessee
shall, if the transferor Lender or the Transferee 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 Transferee, in
each case in principal amounts reflecting their respective Commitments, as
adjusted pursuant to such assignment.

      (c) Rights of Transferees. Each of the Lessee and the Lessor acknowledges
and agrees that each Transferee, for purposes of Sections 13 and 14, shall be
considered a Lender; provided, however, that each of the Lessee and the Lessor
shall have no greater liability to any


                                                      Participation Agreement 49
<PAGE>

Transferee than it would have had to the applicable Lender, except as reflected
in amounts necessary to indemnify such Person on an After-Tax Basis.

      (d) Withholding Taxes; Disclosure of Information; Pledge Under Regulation
A(1). (1) If any Lender (or the assignee in any Note, each a "Transferee") is
organized under the laws of any jurisdiction other than the United States or any
State thereof, then such Participant or Transferee, as applicable, shall (as a
condition precedent to acquiring or participating in such Loan and so long as it
shall be legally entitled to an exemption from withholding as a continuing
obligation to the Lessor and the Lessee), furnish on a timely basis to the
Agent, the Lessor and the Lessee in duplicate, for each taxable year of such
Lender or Transferee during the Lease Term of the Master Lease, a properly
completed and executed copy of either Internal Revenue Service Form W-8ECI or
Internal Revenue Service Form W8-BEN or Internal Revenue Service Form W-9 and
any additional form (or such other form) as is necessary to claim complete
exemption from United States withholding taxes (wherein such Lender or
Transferee claims entitlement to complete exemption from United States
withholding taxes on all payments hereunder), and provide on a timely basis to
the Agent, the Lessor and the Lessee a new Internal Revenue Service Form W-8ECI
or Internal Revenue Service Form W-8BEN or Internal Revenue Service Form W-9 and
any such additional form (or any successor form or forms) upon the expiration or
obsolescence of any previously delivered form and comparable statements in
accordance with applicable United States laws and regulations and amendments
duly executed and completed by such Lender or Transferee, and to comply from
time to time with all applicable United States laws and regulations with regard
to such withholding tax exemption. By its acceptance of a participation or
assignment of a Lender's Note, each Transferee shall be deemed bound by the
provisions set forth in this Section 11.

                  (2) Subject to Section 6(c)(4) hereof (except in the case of
            disclosure of information in connection with Section 11(d)(3)
            below), any Lender may, in connection with any assignment or
            participation or proposed assignment or participation pursuant to
            this Section 11, disclose to the assignee or participant or proposed
            assignee or participant any information relating to the Lessee.

                  (3) Anything in this Section 11 to the contrary
            notwithstanding, any Lender may assign and pledge all or any portion
            of the Notes held by it to any Federal Reserve Bank, the United
            States Treasury or to any other financial institution as collateral
            security pursuant to Regulation A of the F.R.S. Board and any
            operating circular issued by the Federal Reserve System and/or the
            Federal Reserve Bank or otherwise.

SECTION 12. TRANSFERS OF CERTIFICATE HOLDERS' INTEREST.

      (a) Assignments. All or any part of the interest of any Certificate Holder
in, to or under this Participation Agreement, the other Operative Documents, the
Property or the Trust may be assigned or transferred by such Certificate Holder
at any time, subject to the consent of Lessee, which consent shall not be
unreasonably withheld, to (i) any Affiliate of such Certificate Holder, (ii) any
other Participant or any Affiliate of any such other Participant, or (iii) with
the consent of the Agent (such consent not to be unreasonably withheld), to any
other Person; provided, however, that (A) prior to a Lease Event of Default, no
interest shall be assigned to


                                                      Participation Agreement 50
<PAGE>

Lessee or any Affiliate of Lessee; (B) except as provided in (C) below, each
such assignment is in an amount equal to not less than twenty percent (20%) of
the sum of the aggregate amount of the Available Equity Commitments and the
outstanding Equity Amounts of all Certificate Holders (the "Permitted Equity
Assignment Amount"); (C) with respect to an assignment to a Lender or an
Affiliate of a Lender, each such assignment is in an amount equal to not less
than the product of (x) the sum of the Available Equity Commitment, if any, and
outstanding Equity Amounts of the assignor Certificate Holder and (y) the
fraction, expressed as a decimal, obtained by dividing the sum of the Available
Loan Commitments and outstanding principal amount of Loans of such Lender by the
sum of the aggregate amounts of the Available Loan Commitments and Loans of all
Lenders; and (D) in any event, and the assignor Certificate Holder retains an
interest equal to not less than the Permitted Equity Assignment Amount; and,
provided, further, that notice is given to the Owner Trustee and (A) each
assignment or transfer shall comply with all applicable securities laws; and (B)
the assignee, if it is not a Participant immediately prior to such assignment,
will deliver to the Agent a completed administrative questionnaire in form and
substance acceptable to the Agent. The Agent shall receive an administrative fee
of $4,000 from the applicable transferor or transferee in connection with any
assignment or participation under this Section 12. Each assignee or transferee
acknowledges that the obligations to be performed from and after the date of
such transfer or assignment under this Participation Agreement and all other
Operative Documents are its obligations, including the obligations imposed by
this Section 12(a) (and the transferor and transferee Participant shall deliver
to the Lessee and the Lessor an Assignment Agreement, in substantially the form
of Exhibit J-2, executed by the assignee or transferee) and further represents
and warrants to each Participant and the Lessee as set forth in Section 6 and
that:

            (i) it has a net worth or combined capital and surplus of not less
than four (4) times the Certificate Holder's Commitment;

            (ii) it has the requisite power and authority to accept such
assignment or transfer;

            (iii) it will not transfer any interest in the Trust unless the
proposed transferee makes the foregoing representations and covenants;

            (iv) it will not take any action with respect to such interest in
the Trust that would violate any applicable securities laws; and

            (v) it will not assign or transfer any interest in the Trust except
in compliance with this Section 12.

      (b) Rights of Transferees. Each of the Lessee and the Lessor acknowledges
and agrees that each Transferee, for purposes of Sections 13 and 14, shall be
considered a Certificate Holder; provided, however, that each of the Lessee and
the Lessor shall have no greater liability to any Transferee than it would have
had to the applicable Certificate Holder transferor, except as reflected in
amounts necessary to indemnify such Person on an After-Tax Basis.

      (c) Withholding Taxes; Disclosure of Information; Pledge Under Regulation
A(1) . (1) If any Certificate Holder (or the assignee of any Equity Amount, each
also a "Transferee") is


                                                      Participation Agreement 51

State thereof, then such Participant or Transferee, as applicable, shall (as a
condition precedent to acquiring or participating in such Equity Amount and so
long as it shall be legally entitled to an exemption from withholding as a
continuing obligation to the Lessor and the Lessee), furnish on a timely basis
to the Agent, the Lessor and the Lessee in duplicate, for each taxable year of
such Certificate Holder or Transferee during the Lease Term of the Master Lease,
a properly completed and executed copy of either Internal Revenue Service Form
W-8ECI or Internal Revenue Service Form W-8BEN or Internal Revenue Service Form
W-9 and any additional form (or such other form) as is necessary to claim
complete exemption from United States withholding taxes (wherein such Lender,
the Lessor or Transferee claims entitlement to complete exemption from United
States withholding taxes on all payments hereunder), and provide on a timely
basis to the Agent, the Lessor and the Lessee a new Internal Revenue Service
Form W-8ECI or Internal Revenue Service Form W-8BEN or Internal Revenue Service
Form W-9 and any such additional form (or any successor form or forms) upon the
expiration or obsolescence of any previously delivered form and comparable
statements in accordance with applicable United States laws and regulations and
amendments duly executed and completed by such Certificate Holder or Transferee,
and to comply from time to time with all applicable United States laws and
regulations with regard to such withholding tax exemption. By its acceptance of
a participation or assignment of all or any portion of a Certificate Holder's
Equity Amounts, each Transferee shall be deemed bound by the provisions set
forth in this Section 12.

                  (2) Subject to Section 6(c)(4) hereof (except in the case of
            disclosure of information in connection with Section 12(c)(3)
            below), any Certificate Holder may, in connection with any
            assignment or participation or proposed assignment or participation
            pursuant to this Section 12, disclose to the assignee or participant
            or proposed assignee or participant any information relating to the
            Lessee.

                  (3) Anything in this Section 12 to the contrary
            notwithstanding, any Certificate Holder may assign and pledge all or
            any portion of its interest in the Trust held by it to any Federal
            Reserve Bank, the United States Treasury or to any other financial
            institution as collateral security pursuant to Regulation A of the
            F.R.S. Board and any operating circular issued by the Federal
            Reserve System and/or the Federal Reserve Bank or otherwise.

            imposing such taxes or conducting activities therein that are
            unrelated to the Overall Transaction;

                  (3) in the case of each Certificate Holder, (i) net income
            taxes other than net income taxes imposed by jurisdictions in which
            such Indemnitee is not otherwise subject to such taxes to the extent
            such net income taxes exceed the net income taxes that would have
            been payable if such jurisdiction had treated the Master Lease as a
            secured loan consistent with the parties' intention and (ii) other
            taxes that would not have been incurred but for such Indemnitee or a
            person related thereto being organized in the jurisdiction imposing
            such taxes or conducting activities therein that are unrelated to
            the contemplated transactions;

                  (4) in the case of the Lessor, income, franchise, conduct of
            business or similar taxes that are imposed on the Lessor and not the
            Certificate Holders and that, if imposed on the Certificate Holders,
            would not have been indemnified against;

                  (5) Taxes imposed on or measured by the net or gross income,
            excess profits, receipts, minimum or alternative minimum taxable
            income, capital, net worth, tax preferences, accumulated earnings or
            capital gains of a Tax Indemnitee or that are conduct of business,
            doing business or franchise Taxes of such Tax Indemnitee (other than
            any Taxes which are, or are in the nature of, sales, use, value
            added, transfer, excise, rental, license, ad valorem or property
            Taxes imposed by reason of the location, use, operation or presence
            of a Site or any part thereof or a Person which is the Lessee, any
            sublessee, any sub-sublessee, assignee or any other Person using
            through any of the foregoing (including any Affiliate of any of the
            foregoing, but excluding the Lessor, any Participant or any
            Affiliate of any such excluded Person) (each, a "Lessee Person") in
            such jurisdiction or the fact that any payment by a Lessee Person
            contemplated by the Operative Documents is made from such
            jurisdiction) ("Income Taxes") imposed by the United States or any
            state or local government or taxing authority within the United
            States; provided, however, provisions of this clause (5) relating to
            Income Taxes shall not exclude from the indemnity described in this
            Section 13 any state or local Income Taxes imposed by reason of the
            location, use, operation or presence of any Improvement or any part
            thereof in any state in which a Site is located, other than any
            state which such Tax Indemnitee agrees in writing (on or prior to
            the Improvements becoming subject to the Operative Documents) is
            excluded from the indemnity otherwise implied by the proviso to this
            clause 5;

                  (6) Taxes arising out of or measured by acts, omissions,
            events or periods of time (or any combination of the foregoing)
            which occur after (and are not attributable to acts, omissions or
            events occurring contemporaneously with or prior to) the payment in
            full of all amounts payable by the Lessee pursuant to and in
            accordance with the Operative Documents, or the earlier discharge in
            full of the Lessee's payment obligations under and in accordance
            with the Master Lease and the other Operative Documents, and the
            earliest of (x) the expiration of the Lease Term and return of the
            Sites in accordance with the return provisions of the


                                                      Participation Agreement 54
<PAGE>

            Master Lease, (y) the termination of the Master Lease in accordance
            with the applicable provisions of the Master Lease and return or
            disposition of the Sites in accordance with the Master Lease, or (z)
            the termination of the Master Lease in accordance with the
            applicable provisions of the Master Lease and the transfer of all
            right, title and interest in the Sites to the Lessee pursuant to its
            exercise of any of its purchase options (other than sales or other
            transfer taxes as imposed thereon) except that, notwithstanding
            anything to the contrary, Taxes incurred in connection with the
            exercise of any remedies following the occurrence of a Lease Event
            to Default shall not be excluded from the indemnity;

                  (7) Taxes imposed on a Tax Indemnitee that would not have been
            imposed but for the willful misconduct or gross negligence of any
            Tax Indemnitee (other than gross negligence or willful misconduct
            not actually committed by but instead imputed to, such Indemnitee by
            reason of such Tax Indemnitee's participation in the transactions
            and entering into the Operative Documents) or the breach by any Tax
            Indemnitee of any representation, warranty or covenant set forth in
            the Operative Documents;

                  (8) Taxes imposed on a Tax Indemnitee which became payable by
            reason of any transfer or disposition by such Tax Indemnitee of any
            interest in some or all of the Sites, the Operative Documents, any
            other Tax Indemnitee or the Trust Estate other than (A) Taxes that
            result from transfers or dispositions which occur while a Lease
            Event of Default has occurred and is continuing or (B) Taxes that
            result from any transfer or disposition pursuant to the terms of the
            Master Lease (other than Section 19(b) thereof if clause (A) of this
            Section 13(c)(8) is not applicable);

                  (9) Taxes imposed upon the Owner Trustee with respect to any
            trustee's fees for services rendered in its capacity as trustee;

                  (10) Taxes that have been included in Property Cost or
            Transaction Expenses; and

                  (11) If Lessee cannot under Applicable Law pay any Taxes
            directly on behalf of a Tax Indemnitee, the failure of such Tax
            Indemnitee to pay such Taxes for which the Lessee has timely
            advanced the funds to such Tax Indemnitee to pay such Taxes.

Notwithstanding any of the exclusions otherwise set forth in Section 13(c)(1)
through (10), the indemnity set forth in Section 13(b) shall apply to any
Illinois franchise taxes imposed on or with respect to the Lessor if:

      (a)   the Lessor is a Delaware business trust and (i) files its relevant
            Illinois tax returns and reports in a manner consistent with such
            status or (ii) files its relevant Illinois tax returns and reports
            in a manner inconsistent with such status as the result of, or in
            response to, any act, omission or breach of any representation,
            warranty or covenant of a Lessee Person;


                                                      Participation Agreement 55
<PAGE>

      (b)   any Lessee Person prepares or files a Filing (within the meaning of
            Section 13(g) pursuant to Section 13(g)) in a manner inconsistent
            with the status of the Lessor as a Delaware business trust; or

      (c)   the Lessor changes its status from that of a Delaware business trust
            as the result of, or in response to, any act, omission or breach of
            any representation, warranty or covenant of a Lessee Person or in
            connection with the exercise of any remedies following the
            occurrence of a Lease Event of Default.

      (d)   Payments to the Lessee.

                  (1) If any Tax Indemnitee or any Affiliate of any Tax
            Indemnitee actually shall realize a Tax benefit (whether by way of
            deduction, credit, allocation or apportionment or otherwise) with
            respect to a Tax not indemnifiable hereunder which would not have
            been realized but for any Tax with respect to which Lessee has
            reimbursed or indemnified such Tax Indemnitee on an After-Tax Basis
            pursuant to the Operative Documents, which benefit was not
            previously taken into account in determining the amount of the
            Lessee's payment to such Tax Indemnitee, such Tax Indemnitee shall
            pay to the Lessee, on an After-Tax Basis, an amount equal to the
            amount of such Tax benefit; provided, however, that no payment shall
            be made as long as a Payment Default or a Lease Event of Default is
            continuing; provided further, however, that no Tax Indemnitee shall
            be required to pay to the Lessee any Tax benefit to the extent such
            payment is greater than the amount of such Taxes in respect of which
            the reimbursement or indemnification was paid by Lessee, reduced by
            all prior payments by such Tax Indemnitee under this Section 13(d)
            in respect of such amount; any payment to the Lessee which is so
            limited shall, to the extent of such unpaid excess, be carried over
            and shall be available to offset any future obligations of the
            Lessee under this Section 13). If such repaid Tax benefit is
            thereafter lost, the additional Tax payable shall be treated as a
            Tax indemnifiable hereunder without regard to the exclusions set
            forth in Section 13.

                  (2) Upon receipt by a Tax Indemnitee of a refund or credit of
            all or part of any Taxes paid or indemnified against by the Lessee,
            which refund or credit was not previously taken into account in
            determining the amount of the Lessee's payment to such Tax
            Indemnitee, such Tax Indemnitee shall pay to the Lessee, on an
            After-Tax Basis, an amount equal to the amount of such refund, plus
            any interest received by or credited to such Tax Indemnitee with
            respect to such refund; provided, however, that no such payment
            shall be made as long as a Payment Default or a Lease Event of
            Default is continuing.

                  (3) The Tax Indemnitee will, at the Lessee's expense, pursue
            refunds and tax benefits that would result in any such payments to
            the Lessee, but only if the Tax Indemnitee has been notified in
            writing by the Lessee that such refunds or tax benefits are
            available.


                                                      Participation Agreement 56
<PAGE>

      (e) Procedures. Any amount payable to a Tax Indemnitee pursuant to
paragraph 13(b) shall be paid within thirty (30) days after receipt of a written
demand therefor from such Tax Indemnitee accompanied by a written statement
describing in reasonable detail the basis for such indemnity and the computation
of the amount so payable, provided, however, that such amount need not be paid
prior to the later of (i) the date on which such Taxes are due or (ii) in the
case of amounts which are being contested pursuant to paragraph 13(f) hereof,
the time such contest (including all appeals permitted hereunder) is finally
resolved; provided, further, that with respect to Taxes of a recurring nature,
the Tax Indemnitee shall only be required to provide one such written notice.
Any amount payable to the Lessee pursuant to paragraph 13(d) shall be paid
within thirty (30) days of the day on which a return (including estimated tax
returns) is filed reflecting such Tax benefit or promptly after the Tax
Indemnitee actually receives a refund giving rise to a payment under paragraph
13(d), and shall be accompanied by a written statement by the Tax Indemnitee
setting forth in reasonable detail the basis for computing the amount of such
payment. Within thirty (30) days following the Lessee's receipt of any
computation from the Tax Indemnitee, the Lessee may request that an accounting
firm reasonably acceptable to the Tax Indemnitee determine whether such
computations of the Tax Indemnitee are correct. Such accounting firm shall be
requested to make the determination contemplated by this paragraph 13(e) within
thirty (30) days of its selection. In the event such accounting firm shall
determine that such computations are incorrect, such firm shall determine what
it believes to be the correct computations. The Tax Indemnitee shall cooperate
with such accounting firm and supply it with all information necessary to permit
it to accomplish such determination (which information shall be held by such
firm in confidence). The computations of such accounting firm shall be final,
binding and conclusive upon the parties and the Lessee shall have no right to
inspect the books, records or tax returns of the Tax Indemnitee (or the
information supplied by the Tax Indemnitee to the accounting firm) to verify
such computation or for any other purpose. All fees and expenses of the
accounting firm payable under this Section 13(e) shall be borne by the Lessee,
except that if such accounting firm's computation shall result in a decrease in
the amount due from, or an increase in the amount payable to, the Lessee by more
than the greater of 5% or $10,000, then the Tax Indemnitee shall bear the cost
of such accounting firm.

      (f) Contest. If any claim shall be made against any Tax Indemnitee or if
any proceeding shall be commenced against any Tax Indemnitee (including a
written notice of such proceeding) for any Tax as to which the Lessee may have
an indemnity obligation hereunder, or if any Tax Indemnitee shall determine that
any Tax as to which the Lessee may have an indemnity obligation hereunder may be
payable, such Tax Indemnitee shall promptly notify the Lessee in writing and
shall not take any action with respect to such claim, proceeding or Tax without
the consent of the Lessee for thirty (30) days after receipt of such notice by
the Lessee unless the failure to take action could result in the imposition of
penalties or fines or material danger of sale, forfeiture or loss of, or the
creation of any Lien on, the Sites or any portion thereof or interest therein;
provided, however, that any failure to provide such notice shall not relieve the
Lessee of any obligation to indemnify any Tax Indemnitee hereunder unless the
contest is precluded as a result of such failure and such failure arises out of
or is caused by the misconduct or negligence (excluding imputed negligence) of
such Tax Indemnitee; provided, further, however, that if such Tax Indemnitee
shall be required by law or regulation to take action with respect to any such
claim, proceeding or Tax prior to the end of such thirty (30) day period such
Tax Indemnitee shall, in such notice to the Lessee, so inform the Lessee and
such Tax Indemnitee shall not take any action with respect to such claim,
proceeding or Tax without


                                                      Participation Agreement 57
<PAGE>

the consent of the Lessee before the date on which such Tax Indemnitee shall be
required to take action. If, within thirty (30) days after its receipt of such
notice (or such shorter period referred to in the preceding sentence), the
Lessee shall request in writing that such Tax Indemnitee contest the imposition
of such Tax, the Tax Indemnitee shall, at the expense of the Lessee, in good
faith contest (including by pursuit of appeals, excluding any requirement to
appeal to the U.S. Supreme Court), and shall not settle without the Lessee's
consent (such consent not to be unreasonably withheld), or if such contest can
be pursued independently from any other proceeding involving a Tax liability of
such Tax Indemnitee (a "Lessee-Controlled Contest"), the Tax Indemnitee shall
allow the Lessee to contest the validity, applicability or amount of such Tax
(other than withholding or net income Taxes indemnifiable hereunder) by, in the
sole discretion of the Person conducting such contest:

                  (1) resisting payment thereof;

                  (2) not paying the same except under protest, if protest shall
            be necessary and proper; or

                  (3) if payment shall be made, using reasonable efforts to
            obtain a refund thereof in appropriate administrative and judicial
            proceedings;

      provided, however, that in no event shall such Tax Indemnitee be required
      to contest (or permit the Lessee to contest) the imposition of any Tax for
      which the Lessee may be obligated unless: (t) if a Payment Default or a
      Lease Event of a Default shall have occurred and be continuing, Lessee
      shall either (I) provide security for such tax indemnity obligations that
      is reasonably acceptable to such Tax Indemnitee or (II) pay such Tax, (u)
      in the case of net income Taxes indemnifiable hereunder, the amount of the
      claim and all future related claims exceeds $25,000, (v) in the case of
      net income and non-U.S. withholding Taxes indemnifiable hereunder, the
      Lessee shall have delivered to the Certificate Holders an opinion of tax
      counsel chosen by, and reasonably acceptable to, the Certificate Holders
      to the effect that there is substantial authority to contest such claim,
      (w) the Lessee shall have acknowledged in writing its liability hereunder
      if the contest is unsuccessful, (x) the Lessee shall have agreed to pay
      such Tax Indemnitee all costs and expenses that such Tax Indemnitee shall
      incur in connection with contesting such claim (including all reasonable
      legal and accounting fees and disbursements and internally allocated time
      charges), (y) the Certificate Holders shall have reasonably determined
      that action to be taken will not result in any material danger of sale,
      forfeiture or loss of the Sites or any portion thereof or interest therein
      and (z) if such contest shall involve payment of the claim, the Lessee
      shall advance the amount thereof, plus interest, penalties and additions
      to Tax with respect thereto, to such Tax Indemnitee on an interest-free
      basis and on an After-Tax Basis to such Tax Indemnitee. The Tax Indemnitee
      shall consult in good faith with the Lessee regarding the conduct of any
      contest controlled by such Tax Indemnitee and shall allow the Lessee to
      attend all hearings at which unrelated issues are not discussed and to
      comment upon all related submissions in such Tax Indemnitee-controlled
      contests and vice versa. Notwithstanding the above, if Lessee has
      reasonably withheld its consent to settlement, a Tax Indemnitee may settle
      and will not be required to contest the imposition of any Taxes if such
      Tax Indemnitee shall waive its right to indemnity with respect to such
      Taxes and shall have


                                                      Participation Agreement 58
<PAGE>

      paid to the Lessee any and all funds paid by the Lessee to such Tax
      Indemnitee with regard to such contested amount (other than those
      described in clause (x) of this Section 13(f)) plus any interest which the
      Lessee paid on such funds. Any contest by the Lessee or at the Lessee's
      request shall be subject to the following requirements: (i) such contest
      shall be conducted in good faith by appropriate proceedings which have the
      effect of staying the enforcement of the lien for such Taxes and the sale,
      forfeiture or other loss of the applicable Site during the pendency of
      such contest, (ii) none of the Lessor, the Owner Trustee, the Agent and
      the Participants shall be subject to any risk of criminal liability or
      material civil liability by virtue of the matters being contested or such
      proceedings, and (iii) the Lessee, in accordance with prudent practice,
      has set aside adequate reserves for the payment thereof and has provided
      evidence reasonably acceptable to the Agent, the Lessor and the
      Participants of such reserves.

      (g) Reports. In the event any report, return or statement or any
certification or procedure (a "Filing") with respect to Taxes is required to be
made with respect to any Tax that may be subject to indemnification under this
Section 13, the Lessee will, at the Lessee's expense, either prepare and file
such Filing (and in the case of any Filing which is required to be filed on the
basis of individual Sites, such Filing shall be prepared and filed in such
manner as to show as required the interests of each Tax Indemnitee in such
Sites) or, if it shall not be permitted to file the same, it will notify each
Tax Indemnitee of such reporting requirements, prepare such Filing in such
manner as shall be reasonably satisfactory to each Tax Indemnitee and deliver
the same to each Tax Indemnitee within a reasonable period prior to the date the
same is to be filed; provided, however, that the relevant Tax Indemnitees shall
have furnished the Lessee, at the Lessee's request and expense, within a
reasonable time, with such information, not within the control of (nor
reasonably available to) the Lessee, in such Tax Indemnitee's control (or which
is reasonably available to such Tax Indemnitee) and is necessary to complete
such Filing.

      (h) Non-Parties. If a Tax Indemnitee is not a party to this Participation
Agreement, Lessee may require the Tax Indemnitee to agree in writing, in a form
reasonably acceptable to Lessee, to the terms of this Section 13 prior to making
any payment to such Tax Indemnitee under this Section 13.

      (i) Survival. The provisions of this Section 13 shall continue in full
force and effect, notwithstanding the expiration or termination of any Operative
Document, until all obligations hereunder have been met and all liabilities
hereunder paid in full.

      (j) Construction Period. Notwithstanding the foregoing, during the
Construction Period, (i) the Lessor, in lieu of the Lessee, shall indemnify all
Lender Indemnitees under this Section 13, to the same extent that the Lessee is
obligated to so indemnify such parties absent the provisions of this subsection
(j), (ii) the Lessee will indemnify the Lessor for all obligations of the Lessor
under this subsection (j), and (iii) the Lessor hereby assigns to each of the
Lender Indemnitees the Lessor's right to indemnification by the Lessee under
this subsection (j) to the extent of any claim by the respective Lender
Indemnitee under this Section 13. Any indemnification by the Lessor shall be
subject to all of the provisions of this Section 13 to the same extent as
applicable to indemnification by the Lessee under this Section 13.

            Document by the Lessee or any certificate required to be delivered
            pursuant to any Operative Document by the Lessee or any Affiliate;

                  (8) the offer, issue, sale, purchase or delivery of any

            residual contamination on, under or from any Sites and affecting any
            natural resources or any property of others; in any and all such
            circumstances irrespective of whether any of such activities were
            undertaken in accordance with Applicable Law, or whether claims with
            respect thereto are made pursuant to Environmental Law.

      DURING THE LEASE TERM OF ANY SITES, THE LESSEE AGREES THAT NEITHER THE
      CERTIFICATE HOLDERS NOR THE OWNER TRUSTEE (INCLUDING WILMINGTON TRUST
      COMPANY, INDIVIDUALLY) SHALL BE LIABLE TO THE LESSEE FOR ANY CLAIM CAUSED
      DIRECTLY OR


                                                      Participation Agreement 61
<PAGE>

      INDIRECTLY BY THE INADEQUACY OF SUCH SITES OR ANY PART THEREOF FOR ANY
      PURPOSE OR ANY DEFICIENCY OR DEFECT THEREIN OR ANY FAILURE OF TITLE WITH
      RESPECT THERETO (OTHER THAN BY VIRTUE OF LESSOR LIENS OR THE GROSS
      NEGLIGENCE OR WILLFUL MISCONDUCT OF THE CERTIFICATE HOLDERS OR THE OWNER
      TRUSTEE) OR THE USE OR MAINTENANCE THEREOF OR ANY REPAIRS, SERVICING OR
      ADJUSTMENTS THERETO OR ANY DELAY IN PROVIDING OR FAILURE TO PROVIDE ANY
      THEREOF OR ANY INTERRUPTION OR LOSS OF SERVICE OR USE THEREOF OR ANY LOSS
      OF BUSINESS, ALL OF WHICH SHALL BE THE RISK AND RESPONSIBILITY OF THE
      LESSEE.

      (b) Survival. Unless otherwise expressly provided in the Operative
Documents, the obligations, agreements, rights and liabilities of the Lessee,
the Owner Trustee and each Indemnified Person arising under this Section shall
continue in full force and effect, notwithstanding the expiration or other
termination of the Master Lease or this Participation Agreement. Until all
obligations have been met, all liabilities arising under this Section 14 shall
be enforceable by the Lessee, the Owner Trustee and each Indemnified Person and
their successors, assigns and agents.

      (c) Certain Exceptions. Notwithstanding the foregoing, the Lessee shall
not assume liability for or indemnify, defend, protect, save and keep harmless
pursuant to Section 14(a) hereof (i) any Indemnified Person from and against any
Claims to the extent arising out of any act, occurrence or omission (other than
(x) an act or omission of, or an occurrence caused by, or attributable to, the
Lessee or (y) for any Site, if the Lessee shall duly exercise and consummate the
Sale Option with respect to such Site, occurring during or attributable to any
period ending on or before the consummation of such Sale Option) on, under, in
or from any Site after the Return Date with respect to such Site; (ii) any
Indemnified Person for any Claim that is a Tax or a loss of Tax benefits or the
costs and expenses of contesting any Tax or loss of tax benefits, except to
provide indemnification under this Section 14 on an After-Tax Basis; (iii) any
Indemnified Person for any Claim to the extent it results from any failure on
the part of such Indemnified Person to comply with any representation, warranty,
agreement or covenant of such Indemnified Person in favor of the Lessee in any
Operative Document except to the extent such failure to comply resulted from any
default by the Lessee under any Operative Document; provided, however, that the
failure of any Indemnified Person to comply with any such representation,
warranty, agreement or covenant shall not affect the rights of any other
Indemnified Person hereunder; (iv) any Indemnified Person for any Claim to the
extent a court of competent jurisdiction shall have determined that such Claim
results from acts which would constitute the willful misconduct or gross
negligence (or, in the case of an Indemnified Person operating the business
conducted at such Site, negligence) of such Indemnified Person or a related
Indemnified Person (it being agreed that for purposes of this clause (iv) the
Owner Trustee shall be deemed a related Indemnified Person of the Certificate
Holders only to the extent it acts on the written instructions of the
Certificate Holders); provided that: (A) negligence or gross negligence or
willful misconduct will not be imputed to such Indemnified Person, the
Certificate Holders or any related Indemnified Person solely as a result of the
Owner Trustee's ownership of or ground leasehold interest in Sites; (B) the
willful misconduct or gross negligence of an Indemnified Person shall not affect
the rights of any other Indemnified Person


                                                      Participation Agreement 63
<PAGE>

hereunder; and (C) with respect to the Owner Trustee, it shall not constitute
willful misconduct or gross negligence of Wilmington Trust Company to rely on
the written instructions of the Certificate Holders; or (v) a transfer of the
Trust Estate by Certificate Holders or Owner Trustee (other than to Lessee or an
Affiliate of Lessee or as the result of or during a Lease Event of Default or an
Event of Loss).

      The indemnities set forth in this Section shall not constitute a
guarantee, representation or warranty to any Indemnified Person of or as to the
value or useful life of any Site.

      (d) Claims Procedure. An Indemnified Person shall, after obtaining actual
knowledge thereof, promptly notify Lessee of any Claim as to which
indemnification is sought (unless Lessee theretofore has notified such
Indemnified Person of such Claim); provided, however, that the failure to give
such notice shall not release Lessee from any of its obligations under this
Section 14, except to the extent that failure to give notice of any action, suit
or proceeding against such Indemnified Person is shown to increase Lessee's
liability under such Claim from that which would have existed if the failure to
give notice had not occurred. Subject to the following paragraph, Lessee agrees
to defend such Claim and shall at its sole cost and expense be entitled to
control, and shall assume full responsibility for, the defense of such Claim;
provided, however, that Lessee shall keep the Indemnified Person that is the
subject of such proceeding fully apprised of the status of such proceeding and
shall provide such Indemnified Person with all information with respect to such
proceeding as such Indemnified Person reasonably requests; and provided,
further, that in the event Lessee fails to defend such Claim, Lessee shall pay
the reasonable costs and expenses (including reasonable legal fees and expenses)
of the Indemnified Person in defending such Claim.

      Notwithstanding any of the foregoing to the contrary, Lessee shall not be
entitled to control and assume responsibility for the defense of such Claim if
(1) a Lease Default or Lease Event of Default exists, and the Indemnified Person
notifies Lessee that it is no longer permitted to control the defense of such
Claim, (2) such proceeding involves any material danger of the sale, forfeiture
or loss of, or the creation of any Lien (other than any Permitted Lien) on, any
Site, (3) the amounts involved, in the good faith opinion of such Indemnified
Person, are likely to have a materially adverse effect on the business of such
Indemnified Person other than the ownership, leasing and financing of the Sites,
(4) in the good faith opinion of such Indemnified Person, there exists an actual
or potential conflict of interest such that it is advisable for such Indemnified
Person to retain control of such proceeding or (5) such Claim or liability
involves the possibility of criminal actions or liability to such Indemnified
Person. In the circumstances described in clauses (1) through (5), the
Indemnified Person shall be entitled to control and assume responsibility for
the defense of such Claim or liability at the expense of Lessee. In addition,
any Indemnified Person, at its own expense, may (A) participate in any
proceeding controlled by Lessee pursuant to this Section 14(d) and (B) employ
separate counsel. Lessee may in any event participate in all such proceedings at
its own cost. Nothing contained in this Section 14(d) shall be deemed to require
an Indemnified Person to contest any Claim or to assume responsibility for or
control of any judicial proceeding with respect thereto.

      (e) Subrogation. If a Claim indemnified by Lessee under this Section 14 is
paid in full by Lessee and/or an insurer under a policy of insurance maintained
by Lessee, or if payment of the Claim has otherwise been provided for in full in
a manner reasonably satisfactory to the


                                                      Participation Agreement 63
<PAGE>

Indemnified Person, Lessee and/or such insurer, as the case may be, shall be
subrogated to the extent of such payment (or provision) to the rights and
remedies of the Indemnified Person (other than under insurance policies
maintained by such Indemnified Person) on whose behalf such Claim was paid (or
provided for) with respect to the act or event giving rise to such Claim. So
long as no Payment Default and no Lease Event of Default exists, if an
Indemnified Person receives any refund, in whole or in part, with respect to any
Claim paid by Lessee hereunder, it shall promptly pay over the amount refunded
(but not in excess of the amount Lessee or any of its insurers has paid in
respect of such Claim paid or payable by such Indemnified Person on account of
such refund) to Lessee; provided, however, if any Payment Default or Lease Event
of Default exists, any such refund shall be retained by, or paid over to, the
Lessor to be held and applied against amounts payable by the Lessee hereunder
and under the other Operative Documents.

      (f) Insured Claims. In the case of any Claim indemnified by the Lessee
hereunder which is covered by a policy of insurance maintained by or for the
benefit of the Lessee, each Indemnified Person agrees to cooperate, at the
expense of the Lessee, with the insurers in the exercise of their rights to
investigate, defend or compromise such Claim as may be required to retain the
benefits of such insurance with respect to such Claim (but the failure to do so
shall not relieve the Lessee of its obligation to indemnify such Indemnified
Person except to the extent that the Lessee or its insurer is materially
prejudiced as a result of such failure).

      (g) Waiver of Certain Claims. Lessee hereby waives and releases any Claim
now or hereafter existing against any Indemnified Person out of death or
personal injury to personnel of Lessee (including its directors, officers,
employees, agents and servants), loss or damage to property of Lessee or its
Affiliates, of the loss of use of any property of Lessee or its Affiliates,
which may result from or arise out of the condition, use or operation of the
Sites during the Lease Term and the Renewal Term, if any, including, without
limitation, any latent or patent defect whether or not discoverable.

      (h) Consent. Unless an Event of Default shall have occurred and be
continuing, no Indemnified Person shall enter into any settlement or other
compromise with respect to any Claim which is entitled to be indemnified under
this Section 14 without the prior written consent of the Lessee, which consent
shall not be unreasonably withheld, unless such Indemnified Person waives its
right to be indemnified under this Section 14 with respect to such Claim.

      (i) Construction Period. Notwithstanding the foregoing, during the
Construction Period, (i) the Lessor, in lieu of the Lessee, shall indemnify all
Lender Indemnitees under this Section 14, to the same extent that the Lessee is
obligated to so indemnify such parties absent the provisions of this subsection
(i), (ii) the Lessee will indemnify the Lessor for all obligations of the Lessor
under this subsection (i), and (iii) the Lessor hereby assigns to each of the
Lender Indemnitees the Lessor's right to indemnification by the Lessee under
this subsection (i) to the extent of any claim by the respective Lender
Indemnitee under this Section 14. Any indemnification by the Lessor shall be
subject to all of the provisions of this Section 14 to the same extent as
applicable to indemnification by the Lessee under this Section 14.

SECTION 15. TRANSACTION EXPENSES.


                                                      Participation Agreement 64

            Documentation Date, each Site Acquisition Date and each Funding
            Date; provided, however, that if the Lessee has not received written
            invoices therefor at least five (5) Business Days prior to such
            date, such Transaction Expenses shall be paid within thirty (30)
            days after the Lessee has received written invoices therefor.
            Transaction Expenses may, subject to the conditions hereof
            (including without limitation the last sentence of Section 3(a)(1)),
            be paid with the proceeds of an Advance.

                  (2) The Lessee shall pay or cause to be paid all Transaction
            Expenses incurred by the Agent, the Lessor, any Lender or any
            Certificate Holder in entering into any future amendments or
            supplements with respect to any of the Operative Documents, whether
            or not such amendments or supplements are ultimately entered into,
            or giving or withholding of waivers or consents hereto or thereto or
            review of any matter (including, without limitation, the Development
            Agreements), in each case which have been requested by or approved
            by the Lessee, all Transaction Expenses incurred by the Lessee, the
            Lessor, the Agent, the Lenders or the Certificate Holders in
            connection with any purchase of the Property by the Lessee or other
            Person pursuant to Section 6 of the Master Lease and all Transaction
            Expenses incurred by any of the other parties hereto in respect of
            enforcement of any of their rights or remedies against the Lessee or
            any Affiliate of the Lessee in respect of the Operative Documents.

      (b) Brokers' Fees and Stamp Taxes. The Lessee shall pay or cause to be
paid any brokers' fees (other than brokers' fees that are payable solely as a
result of any Participant's breach of the representation set forth in Section
6(a)(vii)) and any and all stamp, transfer and other similar taxes, fees and
excises, if any, including any interest and penalties, which are payable in
connection with the transactions contemplated by this Participation Agreement
and the other Operative Documents.

      (c) Loan Agreement and Related Obligations. Except as provided in the last
sentence of Section 15(a)(1), the Lessee shall pay, before the delinquency date
thereof, all costs, expenses and other amounts (other than principal and
interest on the Loans which are payable to the extent otherwise required by the
Operative Documents) required to be paid by the Lessor under the Loan Agreement,
the Lender Mortgage, the Assignment of Leases and Rents and the Construction
Agency Agreement Assignment.

SECTION 16. CONSENT TO JURISDICTION.

Operative Document or any transaction contemplated


                                                      Participation Agreement 65
<PAGE>

instituted in any state court of competent jurisdiction in the State of Illinois

limitation, inconvenient forum and (iii) submits itself to the jurisdiction of
any state court of competent jurisdiction in the State of Illinois or Federal

other manner permitted by law or to commence legal proceedings or otherwise
proceed against the Lessee in any other jurisdiction.

SECTION 17. LIMITATIONS OF LIABILITY OF OWNER TRUSTEE.

      It is expressly understood and agreed by and among the parties hereto
that, except as otherwise expressly provided herein or therein, each of this
Participation Agreement and the other Operative Documents is executed by
Wilmington Trust Company, not individually or personally but solely as Owner
Trustee under the Trust Agreement in the exercise of the power and authority
conferred and vested in it as such Owner Trustee, that each and all of the
representations, undertakings and agreements herein or therein made on the part
of the Owner Trustee or the Trust are intended not as personal representations,
undertakings and agreements by Wilmington Trust Company, or for the purpose or
with the intention of binding Wilmington Trust Company, personally, but are made
and intended for the purpose of binding only the Trust Estate, that nothing
herein contained shall be construed as creating any liability of Wilmington
Trust Company, or any incorporator or any past, present or future subscriber to
the capital stock of, or stockholder, officer or director of Wilmington Trust
Company, to perform any covenant either express or implied contained herein or
in the other Operative Documents to which the Owner Trustee or the Trust is a
party, and that so far as Wilmington Trust Company is concerned, any Person
shall look solely to the Trust Estate for the performance of any obligation
hereunder or thereunder or under any of the instruments referred to herein or
therein; provided, however, that nothing contained in this Section shall be
construed to limit in scope or substance the general corporate liability of
Wilmington Trust Company, expressly provided (i) to the Certificate Holders
under the Trust Agreement, (ii) in respect of those representations, warranties,
agreements and covenants of Wilmington Trust Company expressly set forth in
Section 7(a) hereof or in any Operative Document to which it is a party or (iii)

is customarily exercised by similar institutions in the receipt and disbursement
of moneys under similar circumstances.

SECTION 18. LIMITATION OF LIABILITY OF CERTIFICATE HOLDERS.

      The Certificate Holders shall not have any obligation or duty to Owner
Trustee, the Lessee, Wilmington Trust Company or to others with respect to the
transactions contemplated hereby, or for any loss arising under the Operative
Documents in respect of a Title Defect, except those obligations or duties of
Certificate Holders expressly set forth in this Participation Agreement and the
other Operative Documents and the Certificate Holders shall not be liable for
performance by any other party of such other party's obligations or duties
hereunder or thereunder. Without limiting the generality of the foregoing, under
no circumstances whatsoever


                                                      Participation Agreement 66
<PAGE>

shall the Certificate Holders be liable for any action or inaction on the part
of Owner Trustee in connection with the transactions contemplated herein,
whether or not such action or inaction is caused by the willful misconduct or
gross negligence of Owner Trustee, unless such action or inaction is taken upon
the written instructions of the Certificate Holders or in violation of the

each of the Participants as its contractual representative hereunder and under
each other Operative Document, and each of the Participants irrevocably
authorizes the Agent to act as the contractual representative of such
Participant with the rights and duties expressly set forth herein and in the
other Operative Documents. The Agent agrees to act as such contractual
representative upon the express conditions contained in this Section 21.
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
Participant by reason of this Participation Agreement or any other Operative
Document and that the Agent is merely acting as the contractual representative
of the


                                                      Participation Agreement 67
<PAGE>

Participants with only those duties as are expressly set forth in this
Participation Agreement and the other Operative Documents. In its capacity as
the Participants' contractual representative, the Agent (i) does not hereby
assume any fiduciary duties to any of the Participants, (ii) is a
"representative" of the Participants 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
Participation Agreement and the other Operative Documents. Each of the
Participants 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 Participant hereby waives.

      (b) Powers. The Agent shall have and may exercise such powers under the
Operative Documents as are specifically delegated to the Agent by the terms of
each thereof, together with such powers as are reasonably incidental thereto.
The Agent shall have no implied duties to the Participants, or any obligation to
the Participants to take any action thereunder except any action specifically
provided by the Operative Documents to be taken by the Agent.

      (c) General Immunity. Neither the Agent nor any of its directors,
officers, agents or employees shall be liable to the Lessee, the Lessor, the
Participants or any Participant for any action taken or omitted to be taken by
it or them hereunder or under any other Operative Document or in connection
herewith or therewith except to the extent such action or inaction is determined
in a final non-appealable judgment by a court of competent jurisdiction to have
arisen from the gross negligence or willful misconduct of such Person.

      (d) No Responsibility for Recitals, etc. Neither the Agent nor any of its
directors, officers, agents or employees shall be responsible for or have any
duty to ascertain, inquire into, or verify (a) any statement, warranty or
representation made in connection with any Operative Document or any advances
thereunder; (b) the performance or observance of any of the covenants or
agreements of any obligor under any Operative Document, including, without
limitation, any agreement by an obligor to furnish information directly to each
Participant; (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 Event of Default; (e) the
validity, enforceability, effectiveness, sufficiency or genuineness of any
Operative 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 Lessee or
any guarantor of any of the Obligations or of any of the Lessee's or any such
guarantor's respective Subsidiaries. The Agent shall have no duty to disclose to
the Participants information that is not required to be furnished by the Lessee
to the Agent at such time, but is voluntarily furnished by the Lessee to the
Agent (either in its capacity as Agent or in its individual capacity).

      (e) Action on Instructions of Participants. The Agent shall in all cases
be fully protected in acting, or in refraining from acting, hereunder and under
any other Operative Document in accordance with written instructions signed by
the Required Participants, and such instructions and any action taken or failure
to act pursuant thereto shall be binding on all of the Participants. The
Participants 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 Participation Agreement or any other Operative Document unless it shall
be requested in writing


                                                      Participation Agreement 68
<PAGE>

to do so by the Required Participants. The Agent shall be fully justified in
failing or refusing to take any action hereunder and under any other Operative
Document unless it shall first be indemnified to its satisfaction by the
Participants 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.

      (f) Employment of Agents and Counsel. The Agent may execute any of its
duties as Agent hereunder and under any other Operative Document by or through
employees, agents, and attorneys-in-fact and shall not be answerable to the
Participants, 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
Participants and all matters pertaining to the Agent's duties hereunder and
under any other Operative Document.

      (g) 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.

      (h) Agent's Reimbursement and Indemnification. The Participants agree to
reimburse and indemnify the Agent ratably in proportion to their respective
Commitments (or, if the Commitments have been terminated, in proportion to their
Commitments immediately prior to such termination) (i) for any amounts not
reimbursed by the Lessee for which the Agent is entitled to reimbursement by the
Lessee under the Operative Documents, (ii) for any other expenses incurred by
the Agent on behalf of the Participants, in connection with the preparation,
execution, delivery, administration and enforcement of the Operative Documents
(including, without limitation, for any expenses incurred by the Agent in
connection with any dispute between the Agent and any Participant or between two
or more of the Participants) 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
Operative 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 Participant or between two or more of the
Participants), or the enforcement of any of the terms of the Operative Documents
or of any such other documents, provided that no Participant 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. The obligations of
the Participants under this Section 21(h) shall survive payment of the
Obligations and termination of this Participation Agreement.

      (i) Notice of Default. The Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default hereunder unless the
Agent has received written notice from a Participant or the Lessee referring to
this Agreement describing such Default or Event of 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 Participants.


                                                      Participation Agreement 69
<PAGE>

      (j) Rights as a Participant. In the event the Agent is a Participant, the
Agent shall have the same rights and powers hereunder and under any other
Operative Document with respect to its Commitment and its Loans as any
Participant and may exercise the same as though it were not the Agent, and the
term "Participant" or "Participants" shall, at any time when the Agent is a
Participant, 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 Participation Agreement
or any other Operative Document, with the Lessee or any of its Subsidiaries in
which the Lessee or such Subsidiary is not restricted hereby from engaging with
any other Person. The Agent, in its individual capacity, is not obligated to
remain a Participant.

      (k) Participant Credit Decision. Each Participant acknowledges that it
has, independently and without reliance upon the Agent, the Arranger or any
other Participant and based on the financial statements prepared by the Lessee
and such other documents and information as it has deemed appropriate, made its
own credit analysis and decision to enter into this Participation Agreement and
the other Operative Documents. Each Participant also acknowledges that it will,
independently and without reliance upon the Agent, the Arranger or any other
Participant 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 Participation Agreement and the other Operative
Documents.

      (l) Successor Agent. The Agent may resign at any time by giving written
notice thereof to the Participants and the Lessee, 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 Participants, such
removal to be effective on the date specified by the Required Participants. Upon
any such resignation or removal, the Required Participants shall have the right
to appoint, on behalf of the Lessee and the Participants, a successor Agent. If
no successor Agent shall have been so appointed by the Required Participants
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 Lessee and the
Participants, a successor Agent. Notwithstanding the previous sentence, the
Agent may at any time without the consent of the Lessee or any Participant,
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 Participants may perform all the duties of the Agent
hereunder and the Lessee shall make all payments in respect of the Obligations
to the applicable Participant and for all other purposes shall deal directly
with the Participants. 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 Operative Documents. After the
effectiveness of the resignation or removal of an Agent, the provisions of this
Section 21 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


                                                      Participation Agreement 70
<PAGE>

under the other Operative 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 21(l), then the term "Prime Rate" as used in
this Participation Agreement shall mean the prime rate, base rate or other
analogous rate of the new Agent.

      (m) Agent's Fee. The Lessee agrees to pay to the Agent, for its own
account, the fees agreed to by the Lessee and the Agent pursuant to the Fee
Letter and the Agent's reasonable fees, costs and expenses for the performance
of Agent's obligations hereunder.

      (n) Delegation to Affiliates. The Lessee and the Participants agree that
the Agent may delegate any of its duties under this Participation 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 Section 13
and 14.

      (o) Execution of Collateral Documents. The Participants hereby empower and
authorize the Agent to execute and deliver to the Lessee on their behalf the
Pledge Agreement and all related financing statements and any financing
statements, agreements, documents or instruments as shall be necessary or
appropriate to effect the purposes of the Pledge Agreement and any other
Operative Document.

      (p) Collateral Releases. The Participants hereby empower and authorize the
Agent to execute and deliver to the Lessee on their behalf any agreements,
documents or instruments as shall be necessary or appropriate to effect any
releases of Collateral which shall be permitted by the terms hereof or of any
other Operative Document or which shall otherwise have been approved by the
Required Participants (or, if required by the terms of Section 22(c), all of the
Participants) in writing.

SECTION 22. MISCELLANEOUS.

      (a) Counterpart Execution. This Participation Agreement may be executed in
any number of counterparts and by the different parties hereto on separate
counterparts, each of which, when so executed and delivered, shall be an
original, but all such counterparts shall together constitute but one and the

      (b) Governing Law. THIS PARTICIPATION AGREEMENT SHALL BE GOVERNED BY, AND
BE CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF ILLINOIS

nor any other Operative Document nor any of the terms hereof or thereof may be

                  (7) without the consent of all Participants, permit the
            creation of any Lien on any of the Sites or any part thereof except
            as contemplated by the Operative Documents, or deprive any
            Participant of the benefit of the security interest and lien secured

Operative Document.

      (d) Headings. The headings of the sections and paragraphs of this

                                                      Participation Agreement 72
<PAGE>

and, except as may otherwise be required by the Master Lease, without any
additional amount accruing with respect thereto, with the same force and effect
as if made on the date when such payment is due.

      (f) Reproduction of Documents. This Participation Agreement, all documents
constituting exhibits hereto, and all documents relating hereto received by a
party hereto, including, without limitation, (a) consents, waivers and
modifications that may hereafter be executed, (b) documents received by
Certificate Holders in connection with Owner Trustee's purchase of the Sites,
and (c) financial statements, certificates, and other information previously or
hereafter furnished to Certificate Holders or Owner Trustee may be reproduced by
the party receiving the same by any photographic, photostatic, microfilm or
other similar process. Each party hereto agrees and stipulates that, to the
extent permitted by law, any such reproduction shall be admissible in evidence
as the original itself in any judicial or administrative proceeding (whether or

reproduction of such reproduction shall likewise be admissible in evidence.

      (g) Opinions. The parties to this Participation Agreement hereby
acknowledge that they have irrevocably instructed their respective counsel to

counsel referred to in and required by Section 9 and Section 13(f) of this
Participation Agreement.

      (h) Survival of Agreements. All agreements, indemnities, representations
and warranties contained in this Participation Agreement or in any agreement,

Agreement and the expiration or other termination of this Participation
Agreement

      (i) Enforcement. Any provision of this Participation Agreement which may
be determined by competent authority to be prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction. To the extent permitted by Applicable Law, the Lessee hereby
waives any provision of law which renders any provision hereof prohibited or
unenforceable in any respect.

      (j) Preservation of Rights. No delay or omission of the Participants or
the Agent to exercise any right under the Operative Documents shall impair such
right or be construed to be a waiver of any Event of Default or an acquiescence
therein, and the making of an Advance notwithstanding the existence of an Event
of Default or the inability of the Lessee to satisfy the 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 or other
variation of the terms, conditions or provisions of the Operative Documents
whatsoever shall be valid unless in writing signed by the Participants required
pursuant to Section 22(c), and then only to the extent in such writing
specifically set forth. All remedies contained in the Operative Documents or by
law


                                                      Participation Agreement 73

afforded shall be cumulative and all shall be available to the Agent and the
Participants until the Obligations have been paid in full.

other Operative Documents, represents the entire agreement of the parties hereto
with respect to the subject matter hereof and supersedes any and all prior
understandings.
