                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                     (UNAUDITED)


BASIS OF PRESENTATION:

These unaudited Consolidated Financial Statements of CenterPoint Properties 
Trust (formerly CenterPoint Properties Corporation - see Note 8), a Maryland 
real estate investment trust, and Subsidiaries (collectively the "Company"), 
have been prepared pursuant to the Securities and Exchange Commission ("SEC") 
rules and regulations and should be read in conjunction with the December 31, 
1996, Financial Statements and Notes thereto included in the Company's Form 
10-K. The following Notes to Consolidated Financial Statements highlight 
significant changes to the Notes included in the December 31, 1996, Audited 
Financial Statements and present interim disclosures as required by the SEC.  
The accompanying Consolidated Financial Statements reflect, in the opinion of 
management, all adjustments necessary for a fair presentation of the interim 
financial statements.  All such adjustments are of a normal and recurring 
nature.  The consolidated balance sheet as of December 31, 1996, has been 
derived from the Company's audited Financial Statements.

The consolidated statements of operations and statements of cash flows for prior
periods have been reclassified to conform with current classifications with no
effect on results of operations or cash flows.

1.  COMMON SHARES OF BENEFICIAL INTEREST AND RELATED TRANSACTIONS

    Under the terms of the Company's 1995 Restricted Stock Incentive Plan,
    adopted in 1995, certain key employees were granted 12,444 restricted
    shares of the Company's common shares of beneficial interest in March,
    1997.  Shares were awarded in the name of each of the participants, who
    have all the rights of other common shareholders, subject to certain
    restrictions and forfeiture provisions.  Restrictions on the shares expire
    no more than eight years after the date of award, or earlier if certain
    performance targets are met.

    Unearned compensation was recorded at the date of award based on the market
    value of the shares.  Unearned compensation, which is shown as a separate
    component of shareholders' equity, is being amortized to expense over the
    eight year vesting period.

    Under the terms of the Company's 1995 Director Stock Plan, adopted in 1995,



<PAGE>


    certain directors were granted 1,921 unrestricted shares of the Company's
    common shares of beneficial interest in May, 1997. Shares were awarded in
    the name of each of the participants, who have all the rights of other
    common shareholders.

    Under the terms of Company's 1993 Stock Option Plan, options for 226,769
    shares of common shares of beneficial interest were granted to officers and
    employees in March, 1997 at $31.50 per share and 15,000 shares of common
    shares of beneficial interest were granted to directors in May, 1997 at
    $30.625 per share.  During the first, second and third quarters of 1997,
    8,624, 1,635, and 12,957 options were exercised.  During the third quarter,
    17,904 options expired due to employee terminations.

    Income per share amounts are based on the weighted average of common and
    common equivalent (share options) shares of beneficial interest outstanding
    of 19,377,337 and 16,685,417 for the three months ended September 30, 1997
    and 1996, respectively, and 18,818,869 and 14,293,487 for the nine months
    ended September 30, 1997 and 1996, respectively.  The assumed conversion of
    convertible subordinated debentures into common shares of beneficial
    interest for purposes of computing fully diluted earnings per share would
    be anti-dilutive.

    In February, 1997, the Financial Accounting Standards Board (FASB) issued
    Statement of Financial Standards (SFAS) No. 128 (SFAS 128), "Earnings per
    Share", effective for financial statements issued after December 15, 1997.
    The Company intends to adopt SFAS 128 in fiscal year 1997.  The Company has
    determined the financial impact to be immaterial for each of the three
    month periods ended and the nine month periods ended September 30, 1997 and
    1996.

    SFAS No. 129, "Disclosure of Information about Capital Structure," was also
    issued in February 1997 and is effective for periods ending after December
    15, 1997.  This statement establishes standards for disclosing information
    about an entity's capital structure by superseding and consolidating
    previously issued accounting standards.  The financial standards of the
    Company are prepared in accordance with the requirements of SFAS No. 129.

    In June, 1997, the FASB issued SFAS Statement No. 130, "Reporting
    Comprehensive Income."  This statement, effective for fiscal years
    beginning after December 15, 1997, would require the Company to report
    components of comprehensive income in a financial statement that is
    displayed with the same prominence as other financial statements.
    Comprehensive income is defined by Concepts Statement No. 6, "Elements of
    Financial Statements" as the change in equity of a business enterprise
    during a period from transactions and other events and circumstances from
    nonowner sources.  It includes all changes in equity distributions to
    owners.  The Company has not yet determined its comprehensive income.



<PAGE>


    In June, 1997, the FASB issued SFAS Statement No. 131, "Disclosures about
    Segments of an Enterprise and Related Information."  This statement,
    effective for financial statements for periods beginning after December 15,
    1997, requires that a public business enterprise report financial and
    descriptive information about its reportable operating segments.
    Generally, financial information is required to be reported on the basis
    that it is used internally for evaluating segment performance and deciding
    how to allocate resources to segments.  This Company has not yet determined
    the impact of this statement on it's financial statements.

    On August 19, 1997, the Company declared a fourth quarter dividend of $0.42
    per share to be paid December 1, 1997 to shareholders of record on November
    10, 1997.

2.  LONG-TERM DEBT AND LINES OF CREDIT

    On September 8, 1997, the Company completed a $55 million tax-exempt bond
    financing for the development of the Company's O'Hare Express air freight
    center.  CenterPoint O'Hare, L.L.C. ("CenterPoint O'Hare"), a subsidiary of
    the Company, is the lessee of approximately 50 acres of land at O'Hare
    International Airport and is constructing the O'Hare Express Center, a
    825,000 square foot air freight forwarding and warehouse complex,
    anticipated to be constructed in three phases over a three-year period.
    The Company arranged for the tax-exempt financing to complete the remainder
    of the O'Hare Express Center through the issuance of City of Chicago
    Variable/Fixed Rate Demand Special Facilities Airport Revenue Bonds
    (CenterPoint O'Hare L.L.C. Project Series 1997) in the principal amount of
    $55 million with an initial term of 35 years which may be extended under
    certain circumstances.  The cash proceeds from the financing are restricted
    for use in completion of the project.  The tax-exempt bonds were issued at
    par with an initial variable interest rate of 4% and were credit enhanced
    by an initial letter of credit issued by The First National Bank of Chicago
    for an initial term of 5 years.  The Company guaranteed CenterPoint
    O'Hare's obligations under the reimbursement agreement pursuant to which
    the initial letter of credit was issued.  In order to maintain the
    tax-exempt status of the bonds, the term of the Ground Lease, under which
    CenterPoint O'Hare leases the approximately 50 acres at O'Hare
    International Airport from the City of Chicago, was shortened from 60 years
    to approximately 45 years but provides CenterPoint O'Hare with an option to
    extend the term for an additional 13 years.

3.  ACQUISITION AND DISPOSITION OF REAL ESTATE

    On January 17, 1997, the Company acquired a fully leased 300,000 square
    foot industrial property located in Waukegan, Illinois for approximately
    $6.4 million in a sale/lease-back transaction.  The acquisition was funded
    with an advance from the Company's line of credit of $5.1 million and the
    balance from working capital.  The seller was Outboard Marine Corporation.

    A fully leased 243,000 square foot industrial property located in West
    Allis,



<PAGE>


    Wisconsin was purchased on April 3, 1997 for approximately $4.7 million.
    The property, purchased from individual investors, was funded entirely with
    an advance from the Company's line of credit.

    The Company acquired an aggregate of 1,664,300 square feet of industrial
    property during May, 1997. On May 14, 1997, four fully leased buildings
    totaling 635,300 square feet and  located in Bedford Park, Illinois were
    acquired for approximately $13.8 million from New York Life Insurance
    Company.   A fully leased 21,000 square foot  property located in Downers
    Grove, Illinois was acquired on May 23, 1997 for approximately $1.0 million
    from LaSalle National Bank, as Trustee.  On May 28, 1997, a 1,008,000
    square foot property located in Montgomery, Illinois was acquired for
    approximately $12.3 million from All-Steel, Inc. The transactions were
    funded with advances from the Company's line of credit totaling of $12.3
    million and the balance from working capital.

    On August 28, 1997, a 888,335 square foot warehouse/industrial building,
    located in Elk Grove Village, Illinois, was purchase from Sears Development
    Co.  The purchase price of approximately $18.0 million was funded with an
    advance on the Company's line of credit of $16.0 million and the balance
    was funded from working capital.

    Two industrial/warehouse properties, totaling 254,796 square feet, were
    purchased during September 1997.  On September 3, 1997, a fully leased
    80,076 square foot facility in Chicago, Illinois was purchased from
    Specialty Steel Products, Inc. for approximately $1.7 million funded with
    working capital.  On September 11, 1997, a 174,720 square foot facility in
    Bedford Park, Illinois was purchased in a sale/lease-back transaction for
    approximately $3.7 million from Petrie Retail, Inc. The acquisition was
    funded with a $3.0 advance on the Company's line of credit and the balance
    was funded from working capital.

    A property, located in Wood Dale, Illinois was sold in June, 1997 for
    approximately $1.7 million upon the execution of a tenant purchase option.

    In September, 1997, an industrial property located in Alsip, IL was sold in
    a transaction qualifying as a tax-free exchange under applicable provisions
    of the Internal Revenue Code.  The consideration for the property was
    approximately $0.7 million.  This amount was used to acquire qualified
    replacement property in the fourth quarter.

4.  MORTGAGE NOTES RECEIVABLE

    In March, 1997, the Company assigned its $4.8 million mortgage note
    receivable, collateralized by a property in Bedford Park, Illinois, for a
    net fee of $176,000.

    In September, 1997, a mortgage note receivable of approximately $0.9
    million was

    repaid upon its maturity date.

5.  INVESTMENT IN AND ADVANCES TO AFFILIATE

    The Company holds approximately 99% of the economic interest in CenterPoint
    Realty Services Corporation ("CRS").  To maintain compliance with
    limitations on income from business activities received by REITs and their
    qualified REIT subsidiaries, the Company holds its interest in CRS in the
    form of non-voting equity ownership which qualifies CRS as an
    unconsolidated taxable subsidiary.


    As of September 30, 1997, the Company had advanced to CRS approximately
    $30.4 million under a demand loan with an interest rate of 8.125%.  The
    proceeds of the loan were applied towards development projects currently
    under construction and the purchase of land held for future development.
    Principal and interest are due upon demand.

    The Company typically purchases development projects upon completion of
    construction on a turn-key basis or develops the property under guaranteed
    maximum price contracts, substantially eliminating any construction risk.

7.  COMMITMENTS AND CONTINGENCIES

    In the normal course of business, from time to time, the Company is
    involved in legal actions relating to the ownership and operations of its
    properties.  In management's opinion, the liabilities, if any, that may
    ultimately result from such legal actions are not expected to have a
    materially adverse effect on the consolidated financial position, results
    of operations and liquidity of the Company.

    The Company has entered into other contracts for the acquisition of
    properties.  Each acquisition is subject to satisfactory completion of due
    diligence and, in the case of development projects, completion and
    occupancy of the project.

    At September 30, 1997, nine of the properties owned are subject to purchase
    options held by certain tenants.  The purchase options are exercisable at
    various intervals through 2006, each for an amount greater than the net
    book value of the asset.  The option to purchase 655 Wheat Lane, Wood Dale,
    IL, was exercised by the tenant, who  purchased the property in June, 1997
    for a purchase price of $1.7 million.  Management is not currently aware of
    planned exercises of other such options and believes that any potential
    exercises would not materially affect the results or prospects of the
    Company.

8.  SUBSEQUENT EVENTS

    To date, four warehouse/industrial properties have been purchased in
    October 1997.



<PAGE>


    A 1,750,000 square foot facility, located in McCook, Illinois, was
    purchased from General Motors Corporation on October 2, 1997 in a
    sale/lease-back transaction.  The purchase price of approximately $5.9
    million was funded with an advance on the Company's line of credit.  On
    October 9, 1997, a 242,690 square foot fully leased building, located in
    Bedford Park, Illinois. was purchased for approximately $5.4 million from
    Sterling Logistics Real Estate Corporation.  The acquisition was funded
    with an advance on the Company's line of credit.  A fully leased 41,976
    square foot property was purchased on October 15, 1997 for approximately
    $1.4 million.  The property, located in Elk Grove Village, Illinois, was
    purchased from NBD Trust Company, as Trustee, and was funded with working
    capital.  On October 23, 1997 a 118,041 square foot industrial building
    located in Romeoville, Illinois was purchased for approximately $2.9
    million.  The acquisition, purchased from McKesson Corporation in a
    sale/lease back transaction, was funded with working capital.

    On October 15, 1997, the Company completed a reorganization pursuant to
    which it converted from a Maryland corporation to a Maryland real estate
    investment trust by means of a merger of CenterPoint Properties Corporation
    (the "Corporation") with and into the Company, which prior to the merger
    was a wholly-owned subsidiary of the Corporation, with the Company as the
    surviving entity.  The reorganization was effected to eliminate the
    obligation  to pay substantial franchise taxes each year in the State of
    Illinois.  Pursuant to a Plan of Reorganization, which was approved by the
    stockholders of the Corporation at a Special Meeting of Stockholders held
    on October 1, 1997, each issued and outstanding share of common stock of
    the corporation, par value $.001 per share (the "Common Stock"), was
    converted into one common share of beneficial interest in the Company, par
    value $.001 per share (the "Common Shares"), each outstanding share of
    Class B common stock of the Corporation was converted into one Class B
    common share of beneficial interest in the Company; and the outstanding
    principal amount of the Corporation's 8.22% Convertible Subordinated
    Debentures due 2004 was assumed by the Company and converted into the same
    principal amount of 8.22% Convertible Subordinated Debentures due 2004 of
    the Company (the "Company Debentures").  The Common Shares and the Company
    Debentures currently trade on the NYSE in the same manner as the Common
    Stock and debentures of the Corporation, respectively, traded on the NYSE
    prior to consummation of the merger.

    No convertible subordinated debentures have been converted since September
    30, 1997.

             ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF
                         OPERATIONS AND FINANCIAL CONDITION.

RESULTS OF OPERATIONS - 1997 COMPARED WITH 1996:

GENERAL BACKGROUND

    The following is a discussion of the historical operating results of the
    Company.  The discussion should be read in conjunction with the Form 10-K
    filed for the fiscal year ended December 31, 1996.

RESULTS OF OPERATIONS

    COMPARISON OF NINE MONTHS ENDED SEPTEMBER 30, 1997 TO NINE MONTHS ENDED
SEPTEMBER     30, 1996.

    Total revenues in the first nine months of 1997 increased by $17.4 million,
    or 39.4%, over the same period last year.  The revenues of the Company are
    derived primarily from base rents and additional rents from expense
    reimbursements, pursuant to the terms of tenant leases for occupied space
    at the warehouse/industrial properties.  These properties represent
    approximately 96% of the gross leasable area of the Company's portfolio as
    of September 30, 1997.

    Operating and investment revenues increased by $17.2 million in 1997.  Full
    period income from properties acquired in 1996 and eleven acquisitions in
    1997 accounted for most of the increase.  Also, mortgage interest income
    contributed $0.6 million in increased operating and investment revenue from
    new mortgages receivable acquired in the second half of 1996.

    Other revenue for the nine months ended September 30, 1997 increased by
    $0.1 million over the same period in 1996, as the volume of merchant
    development business, through real estate fee income and equity in net
    income of affiliate, continues at relatively the same pace as last year.

    Real estate taxes increased $4.2 million, or 50.7%, due to full period
    expenses for 1996 acquisitions and expenses related to 1997 acquisitions.
    Full period expenses from 1996 acquisitions and expenses related to 1997
    acquisitions account for $1.7 of the $2.6 million increase in property
    operating and leasing expense.  Property operating and leasing expense
    includes insurance, utilities, repairs and maintenance and property
    management costs.  The balance, $0.9 million, of the increase is due to
    increased property management costs due to the increase in properties and
    general expense increases throughout the portfolio, most of which are
    reimbursed by tenants.

    General and administrative expenses increased by $0.6 million,  or 34.4%,
    due to the growth of the Company and increased corporate costs, but
    decreased from 3.8% to



<PAGE>


    3.6% of revenue.

    Depreciation and other amortization increased by $3.2 million, from $7.6
    million in 1996 to $10.8 million in 1997.  $2.4 million of the increase is
    due to the full period of depreciation on acquisitions completed during
    1996 and acquisitions to date in 1997, with the balance attributable to
    building improvements.

    Interest incurred increased by $0.4 million over the same period last year
    due to increased average loan balances over the previous, but was partially
    offset by reduced interest rates.

    Amortization of financing costs decreased by $0.3 million due to the
    replacement of secured debt with unsecured debt during the fourth quarter
    of 1996.

    Other income (expense), generally non-operating items, increased in income
    by $0.3 million from the same period last year largely due to a gain on the
    disposition of a property in 1997, whereas disposition of property in 1996
    generated a small loss.

    In 1996, an extraordinary charge of $1.4 million was incurred representing
    the unamortized balance of deferred costs associated with the initial
    funding of the Company's 1991 and 1993 tax exempt bonds.  The bonds were
    refunded by issuing new tax exempt and taxable bonds in 1996.

    As a result of the factors described above, net income increased 75.1%, or
    $8.4 million, from $11.2 million for the first nine months of 1996 to $19.6
    million for the first nine months  1997.  Earnings before interest, income
    taxes, depreciation and amortization for the nine months increased by $10.2
    million, from $28.3 million in 1996 to $38.5 million in 1997.

    The Company reviews it's operating results by comparing Net Revenue Margin
    between periods.  Net Revenue Margin is calculated by dividing net revenue
    (total operating and investment revenue less real estate taxes and property
    operating and leasing expense) by adjusted operating and investment revenue
    (operating and investment revenue less expense reimbursements, adjusted for
    leases containing expense stops).  This margin indicates the percentage of
    revenue actually retained by the Company or, alternatively, the amount of
    operating expenses not recovered by tenant reimbursements.  The margin for
    the first nine months of 1997 was 89.1% compared with 88.2% for the same
    period last year, an increase of 0.9%.

    On a "same-store" basis (comparing the first nine months results of
    operations of 1997, on a cash basis, of the properties owned at January 1,
    1996, with the results of operations of the same properties at September
    30, 1996), the Company recognized a 4.5 % increase in net operating income
    primarily due to the lease-up of vacant spaces, rental increases on renewed
    leases and contractual increases in minimum rent under leases in place.



<PAGE>


    COMPARISON OF THREE MONTHS ENDED SEPTEMBER 30, 1997 TO THREE MONTHS ENDED
    SEPTEMBER 30, 1996,

    Total revenues for the three months ended September 30, 1997 increased by
    $5.9 million or 37.4%, over the same period last year.  Operating and
    investment revenues increased by $5.3 million for the same period in 1997.
    Full period income from properties acquired in 1996 and new acquisitions in
    1997 accounted for most of the increase.

    Other revenue for the three months ended September 30, 1997 increased by
    $0.6 million over the same period in 1996, bringing merchant development
    business, through real estate fee income and equity in net income of
    affiliate, in line with the same pace of a year ago.

    Real estate taxes increased $1.2 million, or 37.9%, due to full period
    expenses for 1996 acquisitions and expense related to 1997 acquisitions.
    Property operating and leasing expenses, which includes insurance,
    utilities, repairs and maintenance and property management costs, increased
    by $0.9 million, or 47.5%.  The increase resulted from full period expenses
    for 1996 acquisitions and expenses related to 1997 acquisitions of $0.5
    million and the balance from operating cost increases throughout the
    portfolio.

    General and administrative expenses increased by $0.4 million,  or 86.4%,
    due to the growth of the Company and increased corporate costs, but
    continues at 3.6% of revenue as does the year to date expenses, a drop of
    0.2% over the same period last year.

    Depreciation and other amortization increased by $1.5 million, from $2.7
    million in 1996 to $4.2 million in 1997.  $0.9 of the increase is due to
    the full period of depreciation on 1996 acquisitions and expense related to
    1997 acquisitions, with the balance attributable to building improvements
    over the past year.

    Interest incurred increased by $0.7 million over the same period last year
    due to an increase in the average loan balance for the quarter over the
    same quarter last year offset by a reduction in interest rates for the
    period.

    Amortization of financing costs decreased by $0.1 million due to the
    replacement of secured debt with unsecured debt during the fourth quarter
    of 1996.

    As a result of the factors described above, net income increased 25.8%, or
    $1.4 million, from $5.3 million for the third quarter of 1996 to $6.7
    million for the third quarter of 1997.  Earnings before interest, income
    taxes, depreciation and amortization for the three months increased by $3.5
    million, from $10.3 million in 1996 to $13.8 million in 1997.



<PAGE>


    The Company reviews it's operating results by comparing Net Revenue Margin
    between periods.  Net Revenue Margin is calculated by dividing net revenue
    (total operating and investment revenue less real estate taxes and property
    operating and leasing expense) by adjusted operating and investment revenue
    (operating and investment revenue less expense reimbursements, adjusted for
    leases containing expense stops). This margin indicates the percentage of
    revenue actually retained by the Company or, alternatively, the amount of
    operating expenses not recovered by tenant reimbursements.  The margin for
    the third quarter of 1997 was 88.7% compared to 86.7% for the third quarter
    of 1996, an increase of 1.0%.

    On a "same-store" basis (comparing the third quarter results of operations
    for 1997, on a cash basis, of the properties owned at July 1, 1996, with
    the results of operations of the same properties for the third quarter of
    1996), the Company recognized a 6.4% increase in net operating income
    primarily due to the lease-up of vacant spaces, rental increases on renewed
    leases and contractual increases in minimum rent under leases in place.

 LIQUIDITY AND CAPITAL RESOURCES

    Cash flow generated from Company operations has historically been utilized
    for working capital purposes and making distributions, while proceeds from
    financings and capital raises have been used to fund acquisitions and other
    capital costs.  For the nine months ended September 30, 1997, cash flow
    from operations was $23.5 million.  Cash flow during the period was used to
    pay $23.1 million of distributions.

    Acquisitions, construction in progress, advances to affiliate, increases to
    mortgage notes receivable, improvements and additions to properties, and
    additions to deferred expenses of approximately $129.5 million for the nine
    months ended September 30,1997 were funded with a net increase in
    borrowings under the Company's line of credit totaling $57.2 million,
    repayment of mortgage notes receivable of $5.7 million, disposition of real
    estate of $2.3 million, and the balance with net proceeds of the public
    offering of common stock.

    At September 30, 1997, the Company's debt constituted approximately 27% of
    its fully diluted market capitalization.  At that date, the Company's fully
    diluted equity market capitalization was approximately $715 million, and
    its fully diluted total market capitalization was approximately $985
    million.  The Company's leverage ratios benefited in the first nine months
    of 1997 from the conversion of approximately $2.6 million of its 8.22%
    Convertible Subordinated Debentures, due 2004, to 141,901 shares of common
    stock.

    At September 30, 1997, the Company had outstanding borrowings of
    approximately $103.3 million under its revolving lines of credit
    (approximately 17% of the Company's fully diluted market capitalization),
    with current remaining availability



<PAGE>


    of approximately $31.7 million.  As of September 30, 1997, the Company's
    line of credit consists of a $135 million unsecured credit facility  co-led
    by First Chicago NBD and Lehman Brothers with participating banks including
    ABN LaSalle, Bank of America, Dresdner Bank AG and NationsBank.  The
    Company is currently negotiating with its lenders to expand the line of
    credit to $150 million in the future.

    On September 8, 1997, the Company completed a $55 million tax-exempt bond
    financing for the development of the Company's O'Hare Express air freight
    center through the issuance of City of Chicago Variable/Fixed Rate Demand
    Special Facilities Airport Revenue Bonds (CenterPoint O'Hare L.L.C. Project
    Series 1997) in the principal amount of $55 million with an initial term of
    35 years which may be extended under certain circumstances.  The tax-exempt
    bonds were issued at par with an initial variable interest rate of 4% and
    were credit enhanced by an initial letter of credit issued by The First
    National Bank of Chicago for an initial term of 5 years.

    Of the net bond proceeds of $53.9 million, $39.8 was invested and
    restricted for completion of the remainder of the O'Hare Express Center,
    $6.0 was used to pay down the Company's line of credit and the balance was
    utilized for working capital.

    On March 6, 1997, the Company completed a public offering of 2,250,000
    shares of common stock at $31.50 per share.  Net proceeds from the
    offering, after the underwriting discounts, were approximately $66.9
    million.  The proceeds of the offering were used to repay approximately
    $58.2 million in borrowings then outstanding under the Company's lines of
    credit, with the balance of $8.7 million to fund working capital
    requirements.  The public offering left the entire amount of the Company's
    line of credit available.

    As of September 30, 1997, the Company had a cash balance of $13.9 million.
    The Company believes that its liquidity is adequate for operations and that
    positive cash flow from operations, supplemented by proceeds of borrowings
    under its lines of credit and other financings, will be adequate to fund
    the Company's acquisition activities and allow distributions to the
    Company's stockholders in accordance with the requirements for
    qualification as a REIT.

    In the first nine months of 1997, the Company declared distributions of
    $23.1 million, representing an annualized distribution rate of
    approximately $1.68 per share.  The following factors, among others, will
    affect the future availability of funds for distribution:  (i)  scheduled
    increases in base rents under existing leases and (ii)  changes in minimum
    base rents attributable to replacement of existing leases with new or
    replacement leases.

                             CENTERPOINT PROPERTIES TRUST
                     PRO FORMA CONDENSED STATEMENTS OF OPERATIONS
              FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1997 AND THE YEAR
                         ENDED DECEMBER 31, 1996 (UNAUDITED)


These unaudited pro forma Condensed Statements of Operations are presented as if
the acquisition of The Sears Property, The Bedford Park Properties and the 1997
Other Acquisitions, the July 2, 1996 offering of common stock, the March 6, 1997
offering of common stock,  the acquisition of properties in 1996, and the
disposition of certain properties in 1996 and 1997 occurred on January 1, 1996.
Such pro forma information is based upon (i) the historical consolidated
statements of operations of CenterPoint Properties Trust and Subsidiaries (the
"Company"); (ii) the statements of revenues and certain expenses of The Sears
Property, The Bedford Park Properties, and the 1997 Other Acquisitions; and
(iii) with respect to the 1996 acquisitions, the adjustments include applicable
revenue and certain expense amounts.  The required audits of statements of
revenues and certain expenses for 1996 acquisitions were included in the
Company's Form 8-K/A filed with the Commission on November 27, 1996.  Revenues
and certain expenses for The Sears Property for the year ended May 31, 1997 are
being used to present the 1996 pro forma results of the Company as information
for the year ended December 31, 1996 is not available.  Management believes that
information for the year ended May 31, 1997 is a fair representation of activity
for this property based on leases in place.  The following should be read in
conjunction with the financial statements and notes thereto included elsewhere
herein.  In the Company's opinion, all adjustments necessary to reflect the
effects of these transactions have been made.

These unaudited pro forma Condensed Statements of Operations are not necessarily
indicative of what actual results of the Company would have been assuming such
transactions had been completed as of January 1, 1996, nor do they purport to
represent the results of operations for future periods.

                           (in thousands except share data)


(A) Decrease reflects the elimination of revenues and expenses included in the
    statements of revenue and certain expenses which are also included in the
    Company's statement of operations since the various dates of acquisition
    (revenues - $2,063;  expenses - $744) plus the elimination of revenues and
    expenses of the properties disposed of during 1997 (revenues - $219;
    expenses - $84).

(B) Increase reflects the interest costs associated with the acquisition of the
    properties (1997 - $1,702;  1996 - $5,372) less the interest savings
    associated with the disposition of properties during 1997 and 1996 (1997 -
    $87;  1996 - $275) less the interest costs eliminated from the application
    of proceeds from the July, 1996 offering of common shares and the March,
    1997 offering of common shares (1997 - $704;  1996 - $6,015).

(C) Increase reflects depreciation expense related to the acquisition of
    properties less the depreciation expenses related to the properties
    disposed of during 1996 and 1997 (1996 - $1,787;  1997 - $614) plus
    amortization expense related to the acquisition of properties less the
    amortization expense related to the properties disposed of during 1996 and
    1997 (1996 - $235;  1997 - $81).

(D) Increase reflects the addition of revenues and expenses included in the
    Company's statements of operations from the properties acquired in 1996
    (revenues - $6,857;  expenses - $3,807) less the elimination of revenues
    and expenses for the properties disposed of during 1996 and 1997 (revenues
    - $1,826;  expenses - $383).

(E) Based on 18,818,869 and 15,008,053 historical (19,338,100 and 18,983,053 -
    pro forma) average number of common and common equivalent shares
    outstanding for the nine months ended September 30, 1997 and the year ended
    December 31, 1996, respectively.  Conversion of all debentures into common
    stock would be anti-dilutive.

                          REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Trustees of
CenterPoint Properties Trust

We have audited the combined statement of revenues and certain expenses of The
Bedford Park Properties as described in Note 1 for the year ended December 31,
1996.  This financial statement is the responsibility of The Bedford Park
Properties' management.  Our responsibility is to express an opinion on this
financial statement based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statement is free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

The accompanying statement was prepared for the purpose of complying with the

    BUSINESS

    The Combined Statement of Revenues and Certain Expenses (the "Statement")

    Trust intends to continue the leasing and management of the properties to
    prospective and existing tenants.  The properties have been acquired in a
    singular transaction involving unrelated third-parties.  A summary of the
    Bedford Park Properties is as follows:

    REVENUE RECOGNITION

    Certain leases of the Bedford Park Properties provide for tenant occupancy
    during periods for which no rent is due or when minimum lease payments
    increase over the term of the lease.  Rental revenues for the full period
    of occupancy are recorded on a straight-line basis over the lives of the
    leases.

    Recoveries from tenants for taxes, insurance and other property operating
    expenses are recognized as revenues in the period the applicable costs are
    incurred.

    ESTIMATES

    The preparation of financial statements in conformity with generally
    accepted accounting principles requires management to make estimates and
    assumptions.  Actual results could differ from those estimates.


2.  FUTURE RENTAL REVENUES

    Under noncancelable operating lease agreements in effect as of December 31,
    1996, tenants are committed to pay, in the aggregate, the following minimum
    base lease rentals:

To the Board of Trustees of
CenterPoint Properties Trust

We have audited the statement of revenues and certain expenses of The Sears
Property as described in Note 1 for the year ended May 31, 1997.  This financial
statement is the responsibility of The Sears Property's management.  Our
responsibility is to express an opinion on this financial statement based on our
audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statement is free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statement.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

The accompanying statement was prepared for the purpose of complying with the
rules and regulations of the Securities and Exchange Commission for inclusion in
the Form 10-Q of CenterPoint Properties Trust and is not intended to be a
complete presentation of The Sears Property's revenues and expenses.

In our opinion, the financial statement referred to above presents fairly, in
all material respects, the revenues and certain expenses of The Sears Property
for the year ended May 31, 1997 in conformity with generally accepted accounting
principles.

the City of Chicago (the "CITY") to O'Hare Tech Center Associates, L.P., 
dated August 15, 1995, as amended by a Corrective and Implementing Supplement

credit to be available to pay principal on the Bonds and up to 45 days' 
interest on the principal of the Bonds at the maximum rate of 12%.

for Unencumbered Assets owned as of the Closing Date), and (f) is materially 
compliant with property related representations and covenants contained in

Stock of such Qualifying Investment Affiliate held by the Guarantor is 
unencumbered, (ii) none of the events described in SECTIONS 9.7, 9.8 or 9.9

the Qualifying Investment Affiliate has become a co-obligor or guarantor on 
the Facility (with liability limited to the applicable Unencumbered Asset) by 
executing and delivering to the Administrative Agent a guaranty in form 
acceptable to the Required Lenders or if the Guarantor's interest in such 
Qualifying Investment Affiliate has been validly pledged for the benefit of 
the Lenders so, pursuant to documents in form and substance reasonably 
satisfactory to the Required Lenders, that the Lenders can succeed to all of 
the Guarantor's rights with respect to such Qualifying Investment Affiliate.

    "UNFUNDED LIABILITIES" means the amount (if any) by which the present value
of all vested nonforfeitable benefits under all Single Employer Plans determined

valuation date for such Plans.

    "UNMATURED DEFAULT" means an event which but for the lapse of time or the

Assets owned by Qualifying Investment Affiliates, plus (c) the amount of 
Unrestricted Cash and Cash Equivalents owned by Guarantor, PLUS (d) the 
allocable share based on Guarantor's economic interest in the amount of 
Unrestricted Cash and Cash Equivalents owned by a Qualifying Investment

equal to the Applicable Cap Rate, the Property Operating Income from each 
Property which is an Unencumbered Asset for such quarter less, without 
duplication, an assumed management fee of 1% of gross revenues (excluding 
tenant recoveries) and the assumed Capital Expenditure Reserve Amount.  If a 
Property is acquired during a quarter then Guarantor shall be entitled to 
include pro forma Property Operating Income from such Property for the entire 
quarter in the foregoing calculation.  If a Property is no longer owned as of 
the last day of a quarter, then no value shall be included for such Property.

    "WHOLLY-OWNED SUBSIDIARY" of a Person means (i) any Subsidiary all of the

and plural forms of the defined terms.



                                      ARTICLE II

                            TERMS OF CREDIT AND DOCUMENTS

    II.1.  AGREEMENT TO PROVIDE CREDIT

          (a) Subject to all of the terms, provisions and conditions set 
forth in this Agreement and the other Credit Documents, the Lenders shall 
cause the Issuing Bank, and the Issuing Bank agrees, to issue the Letter of 
Credit in accordance with all terms, conditions and limitations set forth 
herein.

          (b) The Letter of Credit shall solely provide liquidity and credit 
enhancement with regard to the Bonds.  The Stated Amount of the Letter of 
Credit shall be in the outstanding principal amount of the Bonds, plus an 
interest component as required by the Bond Documents.  The form of the Letter 
of Credit shall be substantially in accordance with the form attached hereto 
as EXHIBIT G and its terms are incorporated herein by reference.  

          (c) The Reimbursement Obligor shall have the right, at any time and 
from time to time, to replace the Issuing Bank with a Lender selected by 
Reimbursement Obligor 


                                      -19-
<PAGE>

(with the consent of such Lender) to issue a Letter of Credit having the same 
Stated Amount, taking into account any permanent reductions of the existing 
Letter of Credit.  In connection with the replacement of any Letter of 
Credit, the Reimbursement Obligor agrees (i) to pay all reasonable expenses 
in connection with any remarketing of Bonds required by the applicable Bond 
Documents, and (ii) to execute all documents and instruments reasonably 
required by Administrative Agent in connection therewith.

          (d) Anything to the contrary in this Agreement contained
notwithstanding, any increase in the Stated Amount of the Letter of Credit or
extension of the Stated Expiration Date of the Letter of Credit shall be subject
to the prior approval of all Lenders.

    II.2   PARTICIPATION.

          (a) Immediately upon issuance by the Issuing Bank of the Letter of 
Credit in accordance with the procedures set forth in SECTION 2.1, each 
Lender shall be deemed to have irrevocably and unconditionally purchased and 
received from the Issuing Bank, without recourse, representation or warranty, 
an undivided interest and participation equal to such Lender's Percentage in 
the Letter of Credit (including, without limitation, all obligations of the 
Borrower with respect thereto) and any security therefor or guaranty 
pertaining thereto.

          (b) In the event that the Issuing Bank makes any payment under the 
Letter of Credit and the Reimbursement Obligor shall not have repaid such 
amount to the Issuing Bank on the date of the Advance, the Issuing Bank shall 
promptly notify the Administrative Agent, which shall promptly notify each 
Lender of the same, and each Lender shall promptly and unconditionally pay to 
the Administrative Agent for the account of the Issuing Bank the amount of 
such Lender's Percentage of the unreimbursed amount of such payment, and the 
Administrative Agent shall promptly pay such amount to the Issuing Bank.  The 
failure of any Lender to make available to the Administrative Agent for the 
account of the Issuing Bank its Percentage of the unreimbursed amount of any 
such payment shall not relieve any other Lender of its obligation hereunder 
to make available to the Administrative Agent for the account of such Issuing 
Bank its Percentage of the unreimbursed amount of any payment on the date 
such payment is to be made, but no Lender shall be responsible for the 
failure of any other Lender to make available to the Administrative Agent its 
Percentage of the unreimbursed amount of any payment on the date such payment 
is to be made.  Any Lender which fails to make any payment required pursuant 
to this SECTION 2.2(b) shall be deemed to be a Defaulting Lender hereunder.

          (c) If the Issuing Bank receives a payment on account of a 
Reimbursement Obligation, including any interest thereon, the Issuing Bank 
shall promptly pay to the Administrative Agent and the Administrative Agent 
shall promptly pay to each Lender which has funded its participating interest 
therein, in immediately available funds, an amount equal to such Lender's 
Percentage thereof.


                                      -20-
<PAGE>

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

    II.3   REIMBURSEMENT OF ADVANCES.  The Reimbursement Obligor agrees to pay
to the Administrative Agent on behalf of the Lenders an amount equal to each
amount drawn under the Letter of Credit.  Each drawing under the Letter of
Credit shall be deemed to be an advance to the Reimbursement Obligor (an
"ADVANCE").

          (a) Any Advance made for the payment of interest on the Bonds
shall be payable no later than five (5) days following the Funding Date of such
Advance.  

          (b) Any Advance made to purchase a Bond tendered for purchase in
accordance with the terms of the Bond Documents shall be payable seven (7) days
following the Funding Date of the Advance except that the Reimbursement Obligor
shall have the right to convert such Advance to a term loan in accordance with
SECTION 3.1 hereof by providing notice to the Administrative Agent of such
election prior to the due date for such Advance.

          (c) Any Advance made in connection with the optional redemption
of Bonds on behalf of the Reimbursement Obligor shall be payable five (5) days
following the Funding Date of the Advance.

          (d) All other Advances, together with accrued and unpaid
interest, shall be immediately due and payable on the date made.

    II.4   INTEREST ON ADVANCES OTHER THAN TERM LOAN ADVANCES.  Each Advance
(other than Term Loan Advances which shall be governed by the provisions of
Article III) shall bear interest from the Funding Date of such Advance to the
date of repayment at a rate per annum equal to the CBR Rate and interest on the
amount of such outstanding Advances shall be payable on the first day of each
month and on the date an Advance is repaid.  Notwithstanding the foregoing,
during the continuance of a Default, interest on outstanding Advances shall
accrue at the Default Rate and shall be payable on demand.

    II.5.  PAYMENT OF REIMBURSEMENT OBLIGATIONS.

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


                                      -21-
<PAGE>

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

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

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

             (iii)  any draft, certificate or any other document presented under
          the Letter of Credit proving to be forged, fraudulent, invalid or
          insufficient in any respect or any statement therein being untrue or
          inaccurate in any respect or any particular conditions stipulated in
          the documents presented under the Letter of Credit are superimposed
          thereon;

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

             (v)  the occurrence of any Default or Unmatured Default;

             (vi)  the failure of any instrument to bear any reference or
          adequate reference to the Letter of Credit, or the failure of any
          draft to be endorsed by the payee or to be accompanied by documents
          at negotiation, or the failure of any negotiating bank to endorse
          any draft or other instrument in connection with the Letter of
          Credit or the failure of any person to note the amount of any draft
          on the reverse of the Letter of Credit or to surrender or take up
          the Letter of Credit or to forward documents apart from drafts as
          required by the terms of the Letter of Credit (each of which
          provisions, if contained in the Letter of Credit itself, may be
          waived by the Issuing Bank);

             (vii)  any error, omission, interruption or delay in transmission
          or delivery of any message or advice in connection with the Letter
          of Credit;

             (viii) any non-documentary conditions that may be stated in the
          Letter of Credit.

The happening of any one or more of the foregoing contingencies shall not
affect, impair, or prevent the obligation of Reimbursement Obligor to make
reimbursement.  In furtherance and 


                                      -22-
<PAGE>

extension and not limitation of the specific provisions hereinabove set 
forth, Reimbursement Obligor and Guarantor agree that any action, inaction or 
omission by the Issuing Bank or any of its branches, affiliates or 
correspondents under or in connection with the Letter of Credit where the 
related drafts, documents or property, is taken in good faith, shall be 
binding on Reimbursement Obligor and Guarantor and shall not, except as set 
forth below, put or create liability on the Issuing Bank or any of its 
branches, affiliates or correspondents.  Issuing Bank, Administrative Agent, 
and the Lender shall not, except as set forth below, be responsible for any 
act, error, neglect, default, omission, insolvency or failure in the business 
of any of the affiliates or correspondents of the Issuing Bank or for any 
refusal by the Issuing Bank to pay or honor drafts drawn under the Letter of 
Credit because of any United States or foreign laws or regulations now or 
hereafter in force or for any other matter beyond the control of such 
parties.  Notwithstanding the foregoing, the Reimbursement Obligor and the 
Guarantor shall have a claim against the Issuing Bank and the Issuing Bank 
shall be liable to the Reimbursement Obligor and the Guarantor, to the extent 
of any actual direct contractual damages (and not indirect, special, 
exemplary, incidental, punitive or consequential damages) suffered by the 
Reimbursement Obligor or the Guarantor which are caused by the Issuing Bank's 
willful misconduct or gross negligence in determining whether documents 
presented under the Letter of Credit comply with the terms thereof.

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

    II.6   ISSUING BANK CHARGES AND EXPENSES.  The Reimbursement Obligor 
agrees to pay to the Issuing Bank a fee of $200 for the issuance of the 
Letter of Credit and $150 for each draw under the Letter of Credit.

    II.7   LETTER OF CREDIT FEE.  The Reimbursement Obligor agrees to pay to 
the Administrative Agent for the account of the Lenders a letter of credit 
fee (the "LETTER OF CREDIT FEE") which shall be computed (on the basis of a 
year of 360 days) at an annual rate equal to the applicable L/C Fee set forth 
in the table attached as EXHIBIT A, multiplied by the Stated Amount.  The 
Letter of Credit Fee for the period beginning on the date of issuance of the 
Letter of Credit and ending on September 30, 1997 shall be payable upon the 
issuance of the Letter of Credit.  Thereafter, the Letter of Credit Fee shall 
be payable quarterly in arrears on the last Business Day of each March, June, 
September and December commencing in December, 1997.  The Letter of Credit 
Fee shall be prorated for any partial quarter that the Letter of Credit is 
outstanding.  


                                      -23-
<PAGE>

    II.8   ISSUER FEE.  The Reimbursement Obligor agrees to pay to the 
Issuing Bank such additional fees as may be set forth in a separate fee 
letter entered into by the Reimbursement Obligor, Guarantor, and 
Administrative Agent.

    II.9   TRANSFER FEE.  The Reimbursement Obligor agrees to pay to the 
Issuing Bank upon each transfer of the Letter of Credit in accordance with 
its terms its reasonable usual and customary charges in connection with such 
transfer, together without duplication all reasonable expenses which the 
Issuing Bank may pay or incur relative to such transfer.

    II.10  INTEREST AND FEE BASIS.  Interest and fees shall be calculated for 
actual days elapsed on the basis of a 360-day year.  Interest shall be 
payable for the day an Advance is made but not for the day of any payment on 
the amount paid if payment is received prior to noon (Chicago time) at the 
place of payment.  If any payment of principal of or interest on an Advance 
shall become due on a day which is not a Business Day, such payment shall be 
made on the next succeeding Business Day and, in the case of a principal 
payment, such extension of time shall be included in computing interest in 
connection with such payment.

    II.11. APPLICABLE MARGINS.  The CBR Applicable Margin and the LIBOR 
Applicable Margin to be used in calculating the interest rate applicable to 
different Types of Advances and the Letter of Credit Fee shall vary from time 
to time in accordance with the ratings from Moody's and/or (as applicable as 
described below) S&P for Guarantor's long-term unsecured debt.  If a rating 
has been issued by only one of S&P or Moody's, that rating shall determine 
the Pricing Category.  In the event both rating agencies have issued a rating 
and the rating agencies are split on the rating for the Guarantor's long-term 
unsecured debt, the lower rating shall be deemed to be the applicable rating 
(e.g., if the Guarantor's Moody's long-term unsecured debt rating is Baa1 and 
its S&P long-term unsecured debt rating is BBB then the Applicable Margins 
shall be computed based on the S&P rating).  Commencing two years after the 
Closing Date, if both rating agencies have not issued a rating for the 
Guarantor's long-term unsecured debt, then Pricing Category 4 shall be 
applicable until such time as both rating agencies have issued a rating.  The 
Applicable Margins shall be adjusted effective on the next Business Day 
following any change in the Guarantor's Moody's long-term unsecured debt 
rating and/or S&P's long-term unsecured debt rating, as the case may be 
(provided that if Administrative Agent does not receive notice of a change in 
rating within forty-five days after it occurs then any reduction in 
Applicable Margin shall be effective only when such notice is received).  The 
applicable debt ratings and the Applicable Margins and Letter of Credit Fee 
(subject to the foregoing) are set forth in the table attached hereto as 
EXHIBIT A.  In the event that either S&P or Moody's shall discontinue their 
ratings of the REIT industry or the Guarantor's long-term unsecured debt, a 
mutually agreeable substitute rating agency shall be selected by the Required 
Lenders and the Guarantor.  If the Required Lenders and the Guarantor cannot 
agree on a substitute rating agency within forty-five (45) days of such 
discontinuance, the Applicable Margin to be used for the calculation of 
interest on Advances hereunder shall be Pricing Category 4.  Lenders 
acknowledge that the rating for Guarantor's unsecured long term debt may be 
issued even though Guarantor has no outstanding unsecured long term debt.


                                      -24-
<PAGE>

    If a rating agency downgrade or discontinuance results in an increase in 
the CBR Applicable Margin or the LIBOR Applicable Margin and if such increase 
is reversed and the affected Applicable Margin is restored within ninety (90) 
days thereafter, at the Guarantor's request, the Guarantor shall receive a 
credit against interest next due the Lenders equal to interest accrued from 
time to time during such period of downgrade or discontinuance and actually 
paid by the Guarantor on the Advances at the differential between such 
Applicable Margins.

    II.12  CURE.  The Reimbursement Obligor agrees to pay to the 
Administrative Agent on demand any amounts advanced by the Lenders to cure 
any default under the Bond Documents.  Administrative Agent will endeavor to 
provide Reimbursement Obligor with two days prior written notice of any such 
advance but the failure to give such notice shall not in any way affect the 
obligation of the Reimbursement Obligor to pay the amount of such advance.  
This provision shall not be construed as obligating and shall not in any way 
obligate the Lenders to cure any such default.

    II.13. METHOD OF PAYMENT.  All payments of the Reimbursement Obligations 
hereunder shall be made, without setoff, deduction, or counterclaim, in 
immediately available funds to the Administrative Agent at the Administrative 
Agent's account specified pursuant to ARTICLE XIV, or at any other Lending 
Installation of the Administrative Agent specified in writing by the 
Administrative Agent to the Reimbursement Obligor, by noon (Chicago time) on 
the date when due and shall be applied ratably by the Administrative Agent 
among the Lenders.  Each payment delivered to the Administrative Agent for 
the account of any Lender shall be delivered promptly by the Administrative 
Agent to such Lender in the same type of funds that the Administrative Agent 
received at its account specified pursuant to ARTICLE XIV or at any Lending 
Installation specified in a notice received by the Administrative Agent from 
such Lender promptly.  If any payment received by the Administrative Agent is 
not delivered to a Lender by the closing of business on the same Business Day 
as received by the Administrative Agent (with respect to payments received by 
2:00 p.m., Chicago time) or the next Business Day (with respect to payments 
received after 2:00 p.m., Chicago time), Lender shall receive from the 
Administrative Agent interest at the Federal Funds Effective Rate on the 
payment.  The Administrative Agent is hereby authorized to charge the 
specific account of the Reimbursement Obligor, if any, maintained with First 
Chicago for such purpose, for each payment of principal, interest and fees as 
it becomes due hereunder.  The Guarantor and Reimbursement Obligor shall not 
have any liability to any Lender for the failure of the Administrative Agent 
to promptly deliver funds to any such Lender and shall be deemed to have made 
all such payments on the date the respective payment is made by the Guarantor 
or Reimbursement Obligor to the Administrative Agent provided that it is 
received by the Administrative Agent no later than the time specified in this 
SECTION 2.13.

    II.14. LENDING INSTALLATIONS.  Each Lender may book its share of Advances
at any Lending Installation selected by such Lender and may change its Lending
Installation from time to time.  All terms of this Agreement shall apply to any
such Lending Installation and the 


                                      -25-
<PAGE>

Notes, if any, shall be deemed held by each Lender for the benefit of such 
Lending Installation.  Each Lender may, by written or telex notice to the 
Administrative Agent and the Reimbursement Obligor, designate a Lending 
Installation through which its share of Advances will be made by it and for 
whose account payments are to be made.

    II.15. NON-RECEIPT OF FUNDS BY THE ADMINISTRATIVE AGENT.  Unless the
Reimbursement Obligor or a Lender, as the case may be, notifies the
Administrative Agent prior to the date on which it is scheduled to make payment
to the Administrative Agent of (i) in the case of a Lender, its Percentage of an
Advance or (ii) in the case of the Reimbursement Obligor, a payment of
principal, interest or fees to the Administrative Agent for the account of the
Lenders, that it does not intend to make such payment, the Administrative Agent
may assume that such payment has been made, the Administrative Agent may, but
shall not be obligated to, make the amount of such payment available to the
intended recipient in reliance upon such assumption.  If the Reimbursement
Obligor has not in fact made such payment to the Administrative Agent, the
recipient of such payment shall, on demand by the Administrative Agent, repay to
the Administrative Agent the amount so made available together with interest
thereon in respect of each day during the period commencing on the date such
amount was so made available by the Administrative Agent until the date the
Administrative Agent recovers such amount at a rate per annum equal to the
Federal Funds Effective Rate for such day.  If a Lender has not in fact made
such payment to the Administrative Agent, the Administrative Agent shall be
entitled to recover such corresponding amount on demand from such Lender
together with interest thereon in respect of each day during the period
commencing on the date such amount was so made available by the Administrative
Agent until the date the Administrative Agent recovers such amount at a rate per
annum equal to the Federal Funds Effective Rate for such date.  If such Lender
does not make such payment upon the Administrative Agent's demand therefor, the
Administrative Agent shall promptly notify the Reimbursement Obligor, and the
Reimbursement Obligor shall immediately pay such amount to the Administrative
Agent together with interest thereon in respect of each day during the period
commencing on the date such amount was so made available by the Administrative
Agent until the date the Administrative Agent recovers such amount at the CBR
Rate.  Nothing in this SECTION 2.15 shall be deemed to relieve any Lender from
its obligation to fulfill any portion of its Obligations hereunder or to
prejudice any rights which the Reimbursement Obligor may have against any Lender
as a result of any default by such Lender hereunder.

    No Lender shall be responsible for any default by any other Lender in its
obligation to fund its Percentage of an Advance, and each Lender shall be
obligated to fund its Percentage of an Advance provided to be made by it
hereunder, regardless of the failure of any other Lender to fund its Percentage.

    II.16. RESERVED.  

    II.17. WITHHOLDING TAX EXEMPTION. At least five Business Days prior to the
first date on which interest or fees are payable hereunder for the account of
any Lender, each Lender that is not incorporated under the laws of the United
States of America, or a state thereof, 


                                      -26-
<PAGE>

agrees that it will deliver to each of the Reimbursement Obligor and the 
Administrative Agent two duly completed copies of United States Internal 
Revenue Service Form 1001 or 4224, certifying in either case that such Lender 
is entitled to receive payments under this Agreement and the Notes without 
deduction or withholding of any United States federal income taxes and an 
Internal Revenue Service Form W-8 or W-9 or applicable successor form, as the 
case may be, to establish an exemption from United States backup withholding 
tax.  Each Lender which so delivers a Form 1001 or 4224 and Form W-8 or W-9 
further undertakes to deliver to each of the Reimbursement Obligor and the 
Administrative Agent two additional copies of such form (or a successor form) 
on or before the date that such form expires (currently, three successive 
calendar years for Form 1001 and one calendar year for Form 4224) or becomes 
obsolete or after the occurrence of any event requiring a change in the most 
recent forms so delivered by it, and such amendments thereto or extensions or 
renewals thereof as may be reasonably requested by the Reimbursement Obligor 
or the Administrative Agent, in each case certifying that such Lender is 
entitled to receive payments under this Agreement and the Notes without 
deduction or withholding of any United States federal income taxes and is 
exempt from backup withholding, unless an event (including without limitation 
any change in treaty, law or regulation) has occurred prior to the date on 
which any such delivery would otherwise be required which renders all such 
forms inapplicable or which would prevent such Lender from duly completing 
and delivering any such form with respect to it and such Lender advises the 
Reimbursement Obligor and the Administrative Agent that it is not capable of 
receiving payments without any deduction or withholding of United States 
federal income tax or is not exempt from backup withholding tax.

    II.18. USURY.  This Agreement and any notes delivered pursuant hereto are
subject to the express condition that at no time shall Reimbursement Obligor be
obligated or required to pay interest on the Obligations at a rate which could
subject any Lender to either civil or criminal liability as a result of being in
excess of the Maximum Legal Rate.  If by the terms of this Agreement or the
Credit Documents, Reimbursement Obligor is at any time required or obligated to
pay interest on the principal balance due hereunder at a rate in excess of the
Maximum Legal Rate, the interest rate or the Default Rate, as the case may be,
shall be deemed to be immediately reduced to the Maximum Legal Rate and all
previous payments in excess of the Maximum Legal Rate shall be deemed to have
been payments in reduction of principal and not on account of the interest due
hereunder.  All sums paid or agreed to be paid to Lender for the use,
forbearance, or detention of the sums due pursuant hereto, shall, to the extent
permitted by applicable law, be amortized, prorated, allocated, and spread
throughout the full stated term of the Loan until payment in full so that the
rate or amount of interest on account of the Obligations does not exceed the
Maximum Legal Rate of interest from time to time in effect and applicable to the
Obligations for so long as the Obligations are outstanding.

    II.19. APPLICATION OF MONEYS RECEIVED. All moneys collected or received by
the Administrative Agent on account of the Facility directly or indirectly,
shall be applied in the following order of priority:


                                      -27-
<PAGE>

        (i)   to the payment of all reasonable costs incurred in the collection
              of such moneys of which the Administrative Agent shall have given
              notice to the Reimbursement Obligor;

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

      (iii)   to the payment of any fees due pursuant to this Agreement; 

       (iv)   to the payment of the whole amount then due and payable on the
              Reimbursement Obligations to the Lenders for principal, together
              with interest thereon at the Default Rate or the interest rate,
              as applicable, (other than a Defaulting Lender) as their
              respective Percentages appear until paid in full; and

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

    II.20. LETTER OF CREDIT COLLATERAL ACCOUNT.  The Reimbursement Obligor
hereby agrees that it will, if required pursuant to SECTION 10.1, maintain a
special collateral account (the "LETTER OF CREDIT COLLATERAL ACCOUNT") at the
Administrative Agent's office at the address specified pursuant to SECTION 15.1,
in the name of the Reimbursement Obligor but under the sole dominion and control
of the Administrative Agent, for the benefit of the Lenders, and in which the
Reimbursement Obligor shall have no interest other than as set forth in
SECTION 10.1.  Such Letter of Credit Collateral Account shall be funded to the
extent required by SECTION 10.1 which shall be applied by the Administrative
Agent in the manner described in Section 10.1.  In addition to the foregoing,
the Reimbursement Obligor hereby grants to the Administrative Agent, for the
benefit of the Lenders, a properly perfected security interest in and to the
Letter of Credit Collateral Account, any funds that may hereafter be on deposit
in such account and the proceeds thereof.  Amounts in the Letter of Credit
Collateral Account may only be invested if Administrative Agent receives an
opinion of counsel or other evidence satisfactory to it that such investment
will not adversely affect the tax exempt status of the Bonds.

                                     ARTICLE III

                                  TERM LOAN FACILITY


    III.1.  CONVERSION TO TERM LOAN.  If there is a draw on the Letter of 
Credit to purchase any tendered Bonds ("LIQUIDITY DRAW") and the Bonds cannot 
be remarketed within the seven (7) day period provided for reimbursement of 
such Advance, then the Reimbursement Obligor shall have the option to convert 
such Advance to a term loan (hereinafter, a "TERM LOAN ADVANCE") which has a 
maturity date on the earlier of (i) the Facility Termination Date, (ii) three 
(3) years following the date of such conversion, and (iii) the date on which 
the Bonds purchased with such Term Loan Advance are remarketed.  If following 
such conversion (and prior to the repayment of such Term Loan Advance) there 
are additional Liquidity Draws that are not reimbursed because the Bonds are 
unable to be remarketed, the maturity date for such additional Term Loan 
Advances shall be the same as for the initial Term Loan Advance.  The only 
Advances that can be converted to Term Loan Advances are Liquidity Draws 
which cannot be reimbursed from the proceeds of remarketing of the applicable 
Bonds purchased with the proceeds of such Liquidity Draws.  All other 
Advances shall continue to be payable at the times set forth in SECTION 2.2.  

    III.2.  CONVERSION AND CONTINUATION OF OUTSTANDING ADVANCES.  All Term 
Loan Advances shall initially be CBR Advances.  CBR Advances shall continue 
as CBR Advances unless and until such CBR Advances are converted into LIBOR 
Advances. Each LIBOR Advance shall continue as a LIBOR Advance until the end 
of the then applicable LIBOR Interest Period therefor, at which time such 
LIBOR Advance shall be automatically converted into a CBR Advance unless the 
Reimbursement Obligor shall have given the Administrative Agent a 
Conversion/Continuation Notice requesting that, at the end of such LIBOR 
Interest Period, such LIBOR Advance shall continue as a LIBOR Advance for the 
same or another LIBOR Interest Period.  Subject to the terms of SECTION 2.7, 
the Reimbursement Obligor may elect from time to time to convert all or any 
part of a Term Loan Advance of any Type into any other Type of Advance; 
provided that any conversion of any LIBOR Advance shall be made on, and only 
on, the last day of the Interest Period applicable thereto unless 
Reimbursement Obligor pays the applicable Break-up Fee.  The Reimbursement 
Obligor shall give the Administrative Agent irrevocable notice (a 
"CONVERSION/CONTINUATION NOTICE") of each conversion of a Term Loan Advance 
not later than 10:00 a.m. (Chicago time) at least one Business Day, in the 
case of a conversion into a CBR Advance, or three Business Days, in the case 
of a conversion into or continuation of a LIBOR Advance, prior to the date of 
the requested conversion or continuation, specifying:

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


                                      -29-
<PAGE>

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

      (iii)   the amount and Type(s) of Advance(s) into which such Advance is
              to be converted or continued and, in the case of a conversion
              into or continuation of a LIBOR Advance, the duration of the
              LIBOR Interest Period applicable thereto.

    III.3.  MINIMUM AMOUNT OF EACH LIBOR ADVANCE.  Each LIBOR Advance shall 
be in the minimum amount of $2,000,000 (and in multiples of $100,000 if in 
excess thereof). Reimbursement Obligor and Guarantor acknowledge that any 
LIBOR Advance not in a multiple of $750,000 or $1,000,000 may result in a 
higher LIBOR Rate.

    III.4.  OPTIONAL PRINCIPAL PAYMENTS.  The Reimbursement Obligor may from 
time to time pay, without penalty or premium, all or any part of outstanding 
Term Loan Advances, upon two Business Days' prior notice to the 
Administrative Agent and each such prepayment shall be in a minimum amount of 
$50,000.00 or in multiples thereof, provided that a LIBOR Advance may not be 
paid prior to the last day of the applicable LIBOR Interest Period unless 
Reimbursement Obligor pays the applicable Break-up Fee.

    III.5.  CHANGES IN INTEREST RATE, ETC. FOR TERM LOAN ADVANCES.  Each CBR 
Advance shall bear interest on the outstanding principal amount thereof, for 
each day from and including the date such Advance is made or is converted 
from a LIBOR Advance into a CBR Advance pursuant to SECTION 3.2 to but 
excluding the date it is paid or is converted into a LIBOR Advance pursuant 
to SECTION 3.2 hereof, at a rate per annum equal to the CBR Rate for such 
day.  Changes in the rate of interest on that portion of any Advance 
maintained as a CBR Advance will take effect simultaneously with each change 
in the Corporate Base Rate.  Each LIBOR Advance shall bear interest from and 
including the first day of the LIBOR Interest Period applicable thereto to 
(but not including) the last day of such LIBOR Interest Period at the LIBOR 
Rate determined as applicable to such LIBOR Advance.

    III.6.  RATES APPLICABLE AFTER DEFAULT FOR TERM LOAN ADVANCES. 
Notwithstanding anything to the contrary contained in SECTION 2.9 or 2.10, 
during the continuance of a Default or Unmatured Default, the Required 
Lenders may, at their option, by written notice to the Reimbursement Obligor 
(which notice may be revoked at the option of the Required Lenders 
notwithstanding any provision of SECTION 9.2 requiring unanimous consent of 
the Lenders to changes in interest rates), declare that no Advance may be 
converted into or continued beyond its current term as a LIBOR Advance.  
During the continuance of a Default the Required Lenders may, at their 
option, by prior written notice to the Reimbursement Obligor (which notice 
may be revoked at the option of the Required Lenders notwithstanding any 
provision of SECTION 9.2 requiring unanimous consent of the Lenders to 
changes in interest rates), declare that each Advance shall bear interest at 
the Default Rate per annum until such Default shall have been cured; provided 
that such rates shall become applicable automatically without notice to the 
Reimbursement Obligor if a Default occurs under SECTION 9.7 or SECTION 9.8.


                                      -30-
<PAGE>

    III.7.  NOTES; TELEPHONIC NOTICES.  If any Advances are converted into 
Term Loan Advances, then at the request of the Administrative Agent, the 
Reimbursement Obligor shall execute and deliver to each of the Lenders a Note 
evidencing such Lender's Percentage of the Term Loan Advance, provided that 
the failure to deliver such Notes shall not affect the obligation of 
Reimbursement Obligor to repay such Term Loan Advances in accordance with the 
terms hereof. If Notes are executed and delivered to the Lenders, each Lender 
is hereby authorized to record the principal amount of each of its Loans and 
each repayment on the schedule attached to its Note, provided, however, that 
the failure to so record shall not affect the Reimbursement Obligor's 
obligations under such Note.  Each Lender's books and records, including 
without limitation, the information, if any, recorded by the Lender on the 
schedule attached to its Note, shall be deemed to be PRIMA FACIA correct 
absent manifest error.  The Reimbursement Obligor hereby authorizes the 
Lenders and the Administrative Agent to extend, convert or continue Advances, 
effect selections of Types of Advances and to transfer funds based on 
telephonic notices made by any person or persons the Administrative Agent or 
any Lender in good faith believes to be an Authorized Officer.  The 
Reimbursement Obligor agrees to deliver promptly to the Administrative Agent 
a written confirmation signed by an Authorized Officer of each telephonic 
notice, if such confirmation is requested by the Administrative Agent or any 
Lender.  If the written confirmation differs in any material respect from the 
action taken by the Administrative Agent and the Lenders, the records of the 
Administrative Agent and the Lenders shall govern absent manifest error.

    III.8.  INTEREST PAYMENT DATES FOR TERM LOAN ADVANCES.  Interest accrued 
on each Term Loan Advance shall be payable on each Payment Date, commencing 
with the first such date to occur after the date an Advance is converted to a 
Term Loan Advance, and at the Facility Termination Date, whether by 
acceleration or otherwise.  Interest accrued on each Term Loan Advance shall 
also be payable on any date on which the Term Loan Advance is prepaid 
(provided that nothing herein shall authorize a prepayment which is not 
otherwise permitted hereunder).  

    III.9.  NOTIFICATION OF INTEREST RATES AND PREPAYMENTS.  Promptly after 
receipt thereof (but in no event later than noon (Chicago time) one Business 
Day prior to the proposed Conversion/Continuation Date for an Advance 
continuing as, or being converted into, a CBR Advance or the close of 
business three Business Days prior to the proposed Conversion/Continuation 
Date for a Term Loan Advance continuing as, or being converted into, a LIBOR 
Advance) the Administrative Agent will notify each Lender of the contents of 
each Conversion/Continuation Notice, and repayment notice received by it 
hereunder.  The Administrative Agent will notify each Lender and the 
Reimbursement Obligor of the interest rate applicable to each LIBOR Advance 
promptly upon determination of such interest rate and will give each Lender 
and the Reimbursement Obligor prompt notice of each change in the Corporate 
Base Rate and the Applicable Margin.

                                      ARTICLE IV

                               CHANGE IN CIRCUMSTANCES


    IV.1.  YIELD PROTECTION.  If, after the date hereof, any law or any 
governmental or quasi-governmental rule, regulation, policy, guideline or 
directive (whether or not having the force of law), or any interpretation 
thereof, or the compliance of any Lender therewith,

        (i)   subjects any Lender or any applicable Lending Installation to any
              tax, duty, charge or withholding on or from payments due from the
              Reimbursement Obligor (excluding federal, state and local income,
              franchise or similar taxes on the overall income of any Lender or
              applicable Lending Installation), or changes the basis of
              taxation of payments to any Lender in respect of amounts due it
              hereunder, or 

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

      (iii)   imposes any other condition the result of which is to increase
              the cost to any Lender or any applicable Lending Installation of
              making, funding or maintaining loans or reduces any amount
              receivable by any Lender or any applicable Lending Installation
              in connection with loans, or requires any Lender or any
              applicable Lending Installation to make any payment calculated by
              reference to the amount of loans held, Letters of Credit issued
              or participated in, or interest received by it, by an amount
              deemed material by such Lender, then, within 15 days of written
              demand by such Lender, the Reimbursement Obligor shall pay such
              Lender that portion of such increased expense incurred or
              reduction in an amount received which such Lender determines is
              attributable to making, funding and maintaining its Loans and its
              Commitment.

    IV.2.  CHANGES IN CAPITAL ADEQUACY REGULATIONS.  If a Lender reasonably 
determines the amount of capital required or expected to be maintained by 
such Lender, any Lending Installation of such Lender or any corporation 
controlling such Lender is increased as a result of a Change (as hereinafter 
defined), then, within fifteen days of written demand by such Lender, the 
Reimbursement Obligor shall pay such Lender the amount necessary to 
compensate for any shortfall in the rate of return on the portion on such 
increased capital which such Lender determines is attributable to this 
Agreement, its Loans, its interest in the 


                                      -32-
<PAGE>

Letter of Credit, or its obligation to make Loans hereunder or participate in 
or issue the Letter of Credit (after taking into account such Lender's 
policies as to capital adequacy).  "CHANGE" means (i) any change after the 
date of this Agreement in the Risk-Based Capital Guidelines or (ii) any 
adoption of or change in any other law, rule, regulation, policy, guideline, 
interpretation, or directive of any Governmental Authority having 
jurisdiction after the date of this Agreement which affects the amount of 
capital required or reasonably expected to be maintained by any Lender or any 
Lending Installation or any corporation controlling any Lender.  "RISK-BASED 
CAPITAL GUIDELINES" means (i) the risk-based capital guidelines in effect in 
the United States on the date of this Agreement, including transition rules, 
and (ii) the corresponding capital regulations promulgated by regulatory 
authorities outside the United States implementing the July 1988 report of 
the Basle Committee on Banking Regulation and Supervisory Practices Entitled 
"INTERNATIONAL CONVERGENCE OF CAPITAL MEASUREMENTS AND CAPITAL STANDARDS," 
including transition rules, and any amendments to such regulations adopted 
prior to the date of this Agreement.

    IV.3.  AVAILABILITY OF LIBOR ADVANCES.  If any Lender determines that 
maintenance of any of its LIBOR Loans at a suitable Lending Installation 
would violate any applicable law, rule, regulation or directive of any 
Governmental Authority having jurisdiction, the Administrative Agent shall 
suspend by written notice to Reimbursement Obligor the availability of LIBOR 
Advances and require any LIBOR Advances to be repaid; or if the Required 
Lenders determine that (i) deposits of a type or maturity appropriate to 
match fund LIBOR Advances are not available, the Administrative Agent shall 
suspend by written notice to Reimbursement Obligor the availability of LIBOR 
Advances with respect to any LIBOR Advances made after the date of any such 
determination, or (ii) an interest rate applicable to a LIBOR Advance does 
not accurately reflect the cost of making a LIBOR Advance, and, if for any 
reason whatsoever the provisions of SECTION 4.1 are inapplicable, the 
Administrative Agent shall suspend by written notice to Reimbursement Obligor 
the availability of LIBOR Advances with respect to any LIBOR Advances made 
after the date of any such determination.

    IV.4.  FUNDING INDEMNIFICATION.  If any payment of a LIBOR Advance occurs 
on a date which is not the last day of the applicable Interest Period, 
whether because of acceleration, prepayment or otherwise, the Reimbursement 
Obligor will indemnify each Lender (other than any Lender whose default was 
the reason that the LIBOR Advance was not made on the date specified), for 
any loss or cost incurred by it resulting therefrom, including,without 
limitation, any loss or cost in liquidating or employing deposits acquired to 
fund or maintain the LIBOR Advance upon Reimbursement Obligor's receipt of 
the written notice pursuant to SECTION 4.5.

    IV.5.  LENDER STATEMENTS; SURVIVAL OF INDEMNITY. To the extent reasonably 
possible, each Lender shall designate an alternate Lending Installation with 
respect to its LIBOR Loans and shall take other measures in its discretion to 
reduce any liability of the Reimbursement Obligor to such Lender under 
SECTIONS 4.1 and 4.2 or to avoid the unavailability of a Type of a LIBOR 
Advance under SECTION 4.3, so long as such designation or other measure is 
not disadvantageous to such Lender.  Each Lender shall deliver a written 
statement of such Lender 


                                      -33-
<PAGE>

to the Administrative Agent and to the Reimbursement Obligor as to the amount 
due, if any, under SECTIONS 4.1, 4.2 or 4.4.  Such written statement shall 
set forth in reasonable detail the calculations upon which such Lender 
determined such amount and shall be final, conclusive and binding on the 
Reimbursement Obligor in the absence of manifest error.  Determination of 
amounts payable under such Sections in connection with a LIBOR Loan shall be 
calculated as though each Lender funded its LIBOR Loan through the purchase 
of a deposit of the type and maturity corresponding to the deposit used as a 
reference in determining the LIBOR Rate applicable to such Loan, whether in 
fact that is the case or not.  Unless otherwise provided herein, the amount 
specified in the written statement shall be payable on demand after receipt 
by the Reimbursement Obligor of the written statement.  The obligations of 
the Reimbursement Obligor under SECTIONS 4.1, 4.2 and 4.4 shall survive 
payment of the Obligations and termination of this Agreement for a period of 
one year.

    IV.6.  LIMITATION ON REIMBURSEMENT OBLIGOR'S LIABILITY.  The 
Reimbursement Obligor shall not be obligated to compensate any Lender 
pursuant to SECTION 4.1, 4.2 or 4.4 for any amounts attributable to a period 
more than one year prior to such Lender's written notice under SECTION 4.5 of 
its intention to seek compensation under SECTION 4.1, 4.2 or 4.4.

                                 CONDITIONS PRECEDENT


    V.1.  ISSUANCE OF LETTER OF CREDIT.  The Issuing Bank shall not be

    A breach of any of the representations and warranties contained in this
    SECTION 7.24 with respect to a Property shall disqualify unless otherwise
    approved by the Required Lenders, such Property from being an Unencumbered
    Asset but shall not constitute a Default (unless the elimination of such
    Property as an Unencumbered Asset results in a Default under one of the
    other provisions of this Agreement including without limitation

lenders named therein (the "Revolving Credit Agreement), delivery of such 
documents in the form and in the manner required under the provisions of the 
Revolving Credit Agreement 


                                      -52-

shall be deemed to satisfy the respective requirements of this Section 8.1 so 
long as Administrative Agent is also the administrative agent under the 
Revolving Credit Agreement.

    VIII.2.  NOTICE OF DEFAULT.  The Guarantor and Reimbursement Obligor will 
give, and will cause each of its Subsidiaries and each Qualifying Investment 
Affiliate to give, prompt notice in writing to the Lenders of the occurrence 
of any Default or Unmatured Default and of any other development, financial 
or otherwise, which could be reasonably likely to have a Material Adverse 
Effect.

    VIII.3.  CONDUCT OF BUSINESS.  The Reimbursement Obligor will do all 
things necessary to remain a validly existing limited liability company in 
good standing in the State of Illinois.  The Guarantor will do, and will 
cause each of its Subsidiaries and Qualifying Investment Affiliates to do, 
all things necessary to remain duly incorporated and/or duly qualified, 
validly existing and in good standing as a real estate investment trust, 
corporation, general partnership, limited liability company or limited 
partnership, as the case may be, in its jurisdiction of 
incorporation/formation, except, with respect to any Subsidiary or any 
Qualifying Investment Affiliate having less than $10,000,000 of Market 
Capitalization, where the preservation of its corporate existence, in the 
good faith business judgment of the Guarantor, is no longer in the best 
interests of the Guarantor and the failure to preserve its corporate 
existence would not have a Material Adverse Effect and the elimination of its 
Properties from the calculation of financial covenant compliance would not 
cause a Default or an Unmatured Default.  The Guarantor will maintain all 
requisite authority to conduct its business in each jurisdiction in which the 
Properties are located and, except where the failure to be so qualified would 
not have a Material Adverse Effect, in each jurisdiction required to carry on 
and conduct its businesses in substantially the same manner as it is 
presently conducted, and, specifically, neither the Guarantor nor its 
Subsidiaries nor the Qualifying Investment Affiliates will undertake any 
business other than the acquisition, development, ownership, management, 
operation and leasing of warehouse/industrial properties and ancillary 
businesses specifically related thereto, except that the Guarantor and its 
Subsidiaries and Qualifying Investment Affiliates may invest in other assets 
subject to the following limitations with respect to the specified categories 
of assets:

no event shall the Guarantor declare or pay dividends on its Capital Stock if 
dividends paid in any period of four fiscal quarters, in the aggregate, would 
exceed 90% of Funds From Operations for such period.  Notwithstanding the 
foregoing, unless at the time of distribution there exists a Default in the 
payment of principal, interest, or the Letter of Credit Fee, the Guarantor 
shall be permitted to distribute whatever amount of dividends is necessary to 
maintain its tax status as a real estate investment trust.

    VIII.11. MERGER; SALE OR TRANSFER OF ASSETS.  The Reimbursement Obligor 
and Guarantor will not, nor will they permit any of their Subsidiaries or 
Qualifying Investment Affiliates to, enter into any merger, consolidation, 
reorganization or liquidation or transfer or otherwise dispose of all or a 
portion of their Property if such disposition would constitute a "RESTRICTED 
DISPOSITION," except for (i) such transactions that occur between 
Wholly-Owned Subsidiaries, (ii) transactions where Guarantor is the surviving 
entity and there is no change in business conducted or loss of an investment 
grade rating on such entity's long-term unsecured debt and no other Default

"RESTRICTED DISPOSITION" shall mean any disposition of assets (exclusive of 
Like-Kind Exchanges of one industrial/warehouse property for another and 
dispositions of Non-industrial Properties) if such disposition is of assets 
that (i) when aggregated with all other assets of the Guarantor, its 
Subsidiaries and Qualifying Investment Affiliates previously disposed of

industrial/warehouse property for another and dispositions of Non-industrial 
Properties), comprise more than 10% of Market Capitalization for the most 
recent available quarter or (ii) when aggregated with all other assets of the 
Guarantor, its Subsidiaries and Qualifying Investment Affiliates previously

of (other than the creation or incurrence of Liens permitted under SECTION 
8.16) an Unencumbered Asset (excluding its Non-industrial Properties) without 
the prior written consent of Lenders holding 51% or more of the Aggregate 
Commitment if such Unencumbered Asset, together with any other Unencumbered 
Assets (excluding the Non-industrial Properties) which have been disposed of 
during the period of four fiscal quarters ending with the quarter during 
which such transfer occurs, have a value which exceeds 20% of the Value of 
Unencumbered Assets (as determined at the beginning of such four quarter 
period and increased to reflect the acquisition of Unencumbered Assets during 
such four quarter period) or if such transfer would result in a violation of 
the covenants contained in SECTIONS 8.20 and 8.21.

    VIII.13. TRANSFER OR ENCUMBRANCE OF THE O'HARE PROJECT.  The 
Reimbursement Obligor shall not transfer, encumber, or otherwise dispose of 
its interest or any part thereof in the O'Hare Project or any revenues 
derived from the operation of the O'Hare Project while the Letter of Credit 
is outstanding; provided, however, the foregoing shall not in any manner 
affect the ability of the Reimbursement Obligor to convey leasehold interests

operation of the O'Hare Project (to the extent such distributions are 
permitted under Section 8.10).

    VIII.14. OWNERSHIP AND CONTROL.  The Guarantor's management (president,

vested options) of a minimum 550,000 common shares of the Guarantor adjusted 
for stock splits, provided that if Guarantor's management and directors fail

Lenders of such lower level of ownership.  The Guarantor shall not permit a 
Change of Control to occur.

    VIII.15. SUBSIDIARIES AND QUALIFYING INVESTMENT AFFILIATES.  In the event 
that Guarantor shall, directly or indirectly, transfer or otherwise dispose 
of the Capital Stock (other than intercompany transfers where following such 
transfer the assets of the Subsidiary or Qualifying Investment Affiliate 
still meet the requirements for being an Unencumbered Asset) or other 
ownership interests in any Subsidiaries or Qualifying Investment Affiliates, 
such transfer or disposal shall be treated as though the applicable 
Subsidiary or Qualifying Investment Affiliate had disposed of its assets for 
purposes of determining whether such disposition is a Restricted Disposition 
as defined in SECTION 8.11 or whether such disposition requires a written 
consent of Lenders pursuant to SECTION 8.12.

    VIII.16. LIENS.  The Guarantor and Reimbursement Obligor will not, nor

              aside on its books;

      (iii)   Liens arising out of pledges or deposits under worker's

              properties of a similar character and which do not in any
              material way affect the marketability of the same or interfere
              with the use thereof in the business of the Guarantor or its
              Subsidiaries or Qualifying Investment Affiliates;

        (v)   Liens of any Subsidiary or Investment Affiliate in favor of the
              Guarantor;

       (vi)   Liens existing on the date hereof and described in SCHEDULE 3
              hereto; and

      (vii)   Liens arising in connection with any Indebtedness permitted
              hereunder to the extent such Liens will not result in a violation
              of any of the provisions of this Agreement.

Liens permitted pursuant to this SECTION 8.16 shall be deemed to be "PERMITTED
LIENS".

    VIII.17. AFFILIATES.  The Guarantor and Reimbursement Obligor will not, 
nor will they permit any of their Subsidiaries or Qualifying Investment 
Affiliates to, enter into any transaction (including, without limitation, the

transfer to, any Affiliate except in the ordinary course of business and 
pursuant to the reasonable requirements of the applicable entity's business 
and upon fair and reasonable terms no less favorable to the Guarantor,

    contested in good faith by appropriate proceedings and the pendency of such
    proceedings could not be reasonably expected to have a Material Adverse
    Effect, or (b) the Guarantor has determined in good faith that contesting

    and the failure to contest the same could not be reasonably expected to
    have a Material Adverse Effect;

      (iii)   defend, indemnify and hold harmless the Administrative Agent, the
    Documentation Agent and each Lender, and their respective employees,
    agents, officers and directors, from and against any claims, demands,

    liable, including, without limitation, reasonable attorney's and
    consultant's fees, investigation and laboratory fees, response costs, court
    costs and litigation expenses, except to the extent that any of the

    party seeking indemnification therefor.  This indemnity shall continue in
    full force and effect regardless of the termination of this Agreement; and

       (iv)   prior to the acquisition of a new Property after the Closing

UCC, tax lien, judgment and litigation searches with respect to Guarantor and 
each Qualifying Investment Affiliate that owns an Unencumbered Asset, and (b)

                                      ARTICLE X

                    ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES


    X.1. ACCELERATION AND OTHER REMEDIES.  If any Default occurs and is 
continuing the Issuing Bank may, and upon direction of the Required Lenders 
shall, terminate the Letter of Credit and/or declare all Reimbursement 
Obligations to be immediately due and payable.  If any Default occurs and is 
continuing, the Issuing Bank, at the request of the Required Lenders, shall 
direct the Trustee to declare the Bonds to be due and payable or to direct 
that Bonds be called for redemption as provided in the Paragraph entitled 
"Mandatory Redemption at the Direction of the Bank" as provided in Section 8 
of the Bonds. A copy of such notice shall be sent to the Reimbursement 
Obligor.  If the Letter of Credit has not been replaced at least five days 
before a notice of redemption of the Bonds is due to be issued by the Trustee 
under Section 8 of the Bonds because of the pending expiration of the Letter 
of Credit, the Issuing Bank may, with the consent of all Lenders, elect to 
extend the Stated Expiration Date of the Letter of Credit for such period as 
it determines by issuing a notice in the form of Exhibit H to the Letter of 
Credit and Reimbursement Obligor and Guarantor hereby consent to any such 
extension and acknowledge that such extension shall not be deemed to cure or 
satisfy the Default.  Reimbursement Obligor and Guarantor hereby confirm that 
their obligations pursuant to this Agreement and the Guaranty shall not be 
affected by such amendments and they agree to execute such documentation as 
Administrative Agent may require in connection with any such extension but 
the absence of such documentation shall in no way limit or affect their 
respective obligations.


                                      -67-
<PAGE>

    In addition to the foregoing, following the occurrence and during the 
continuance of a Default and so long as the Letter of Credit has not been 
fully drawn and has not been cancelled or expired by its terms or terminated 
by the Lenders under this Section 10.1, upon demand by the Administrative 
Agent, the Reimbursement Obligor shall establish and deposit in the Letter of 
Credit Collateral Account cash in an amount equal to the aggregate undrawn 
face amount of the Letter of Credit and all fees and other amounts due or 
which may become due with respect thereto.  The Reimbursement Obligor shall 
have no control over funds in the Letter of Credit Collateral Account, which 
funds will be invested by the Administrative Agent from time to time at its 
discretion in certificates of deposit of First Chicago having a maturity not 
exceeding 30 days.  Such funds shall be promptly applied by the 
Administrative Agent to reimburse any Issuing Bank for drafts drawn from time 
to time under the Letter of Credit.  Such funds, if any, remaining in the 
Letter of Credit Collateral Account following the payment of all obligations 
under the Credit Documents in full shall, unless Administrative Agent is 
otherwise directed by a court of competent jurisdiction, be promptly paid 
over to the Reimbursement Obligor.

    X.2. AMENDMENTS, WAIVERS, DECISIONS.  Subject to the provisions of this 
ARTICLE X, the Required Lenders (or the Administrative Agent with the consent 
or direction in writing of the Required Lenders), the Guarantor and the 
Reimbursement Obligor may enter into agreements supplemental hereto for the 
purpose of adding or modifying any provisions to the Credit Documents or 
changing in any manner the rights of the Lenders or the Reimbursement Obligor 
hereunder, releasing any Restricted Unencumbered Assets from the Negative 
Pledge Agreements, if applicable or waiving any Default hereunder; PROVIDED, 
HOWEVER, that no such supplemental agreement shall, without the consent of 
all Lenders:

        (i)   Extend the Facility Termination Date (except for an extension of
              the Letter of Credit in accordance with SECTION 10.1 to prevent a
              redemption of the Bonds) or forgive all or any portion of the
              Obligations, reduce the Applicable Margins on the underlying
              interest rate options or otherwise modify or add to such interest
              rate options, or extend the time of payment of any of the
              Obligations.

       (ii)   Reduce the percentage specified in the definition of Required
              Lenders or  change any provision that currently requires an
              approval from the Required Lenders, all Lenders or the specific
              Lender affected, to approval by a different standard.

      (iii)   Increase the amount of the Aggregate Commitment.

       (iv)   Permit the Reimbursement Obligor to assign its rights under this
              Agreement.

        (v)   Amend SECTION 2.2, 2.3, 3.8(a), 13.2, or this SECTION 10.2.

                                      -68-
<PAGE>

       (vi)   Release or limit the liability of Guarantor or any guarantor with
              respect to the Obligations.

No amendment of any provision of this Agreement relating to the 
Administrative Agent shall be effective without the written consent of the 
Administrative Agent, and no amendment increasing the Commitment of any 
Lender shall be effective without the written consent of such Lender.

    X.3. PRESERVATION OF RIGHTS.  No delay or omission of the Lenders or the 
Administrative Agent to exercise any right under the Credit Documents shall 
impair such right or be construed to be a waiver of any Default or an 
acquiescence therein, and the making of a Loan notwithstanding the existence 
of a Default or the inability of the Guarantor to satisfy the conditions 
precedent to such Loan shall not constitute any waiver or acquiescence.  Any 
single or partial exercise of any such right shall not preclude other or 
further exercise thereof or the exercise of any other right, and no waiver, 
amendment or other variation of the terms, conditions or provisions of the 
Credit Documents whatsoever shall be valid unless in writing signed by the 
Lenders required pursuant to SECTION 10.2, and then only to the extent in 
such writing specifically set forth.  All remedies contained in the Credit 
Documents or by law afforded shall be cumulative and all shall be available 
to the Administrative Agent and the Lenders until the Obligations have been 
paid in full.

                                      ARTICLE XI

authority in respect of the Credit Documents shall be paid by the 
Reimbursement Obligor, together with interest and penalties, if any.

    XI.4. HEADINGS.  Section headings in the Credit Documents are for

    XI.5. ENTIRE AGREEMENT.  The Credit Documents embody the entire agreement 
and understanding among the Reimbursement Obligor, Guarantor, the 
Administrative Agent, and the Lenders and supersede all prior commitments,

    XI.6. SEVERAL OBLIGATIONS; BENEFITS OF THIS AGREEMENT.  The respective 
obligations of the Lenders hereunder are several and not joint and no Lender

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

paid or incurred by the Arranger (whether in their capacity as arrangers, or,

agrees to reimburse the Arranger, Administrative Agent, and the Lenders for 
any costs, internal charges and reasonable out-of-pocket expenses (including, 
without limitation, all reasonable fees and expenses for attorneys for the 
Arrangers, Administrative Agent and the Lenders, which attorneys may be

in connection with the collection and enforcement of the Credit Documents 
(including, without limitation, any workout).  The Reimbursement Obligor

pay or incur arising out of or relating to this Agreement, the other Credit 
Documents, the Properties, the transactions contemplated hereby or the direct 
or indirect application or proposed application of the proceeds of any 
Advance hereunder; provided, however, the Reimbursement Obligor shall not 
have any liability for any claim, loss, cost or expense arising from (i) the 
gross negligence or wilful misconduct of the party seeking to be indemnified, 
(ii) a misrepresentation in materials provided by any of the Lenders or their 
agents for inclusion in the preliminary or final Private Placement Memorandum 
or re-marketing circular prepared in connection with the sale or re-marketing 
of the Bonds, or (iii) the refusal or inability of an Issuing Bank to pay a

Credit.  The obligations of the Reimbursement Obligor under this SECTION 11.7 
shall survive for two years after the termination of this Agreement.

Reimbursement Obligor.  Neither the Administrative Agent, the Arranger nor 
any Lender undertakes any responsibility to the Reimbursement Obligor to

Affiliate that it is entitled to compensation in connection with the 
financing contemplated hereby. Administrative Agent hereby agrees to 
indemnify and save Reimbursement Obligor and Guarantor harmless from and

agree that, to the extent that such information therein contained has not 
theretofore otherwise been disclosed in such a manner as to render such 
information no longer confidential, such Lender and such assignee will employ 
reasonable procedures reasonably designed to maintain the confidential nature 
of the information therein contained; provided that anything herein contained 
to the contrary notwithstanding, any Lender or its assignee may disclose or 
disseminate such information to:  (a) its affiliates; (b) employees, agents, 
attorneys and accountants of such Lender, or their respective affiliates who 
would ordinarily have access to such information in the normal course of the 
performance of their duties; (c) such third parties as such Lender may deem

governmental or industry agency, commission, authority, board or similar 
entity or in connection with any proceeding, case or matter pending (or on 
its face purported to be pending) before any court, tribunal, arbitration 
board or any governmental agency, commission, authority, board or similar 
entity; and (d) any prospective assignee of or Participant in such Lender's 
interest, provided such prospective assignee or Participant agrees in writing 
to be bound by these provisions.

hereunder or any other documents which may be delivered in connection 
herewith shall be stated to be due on a day which is not a Business Day, such

                                      -74-
<PAGE>

    XII.1. APPOINTMENT.  Subject to the provisions of SECTION 12.11, The 
First National Bank of Chicago is hereby appointed Administrative Agent 
hereunder and under each other Credit Document, and each of the Lenders 
irrevocably authorizes the Administrative Agent to act as the agent of such 
Lender.  The Administrative Agent agrees to act as such upon the express 
conditions contained in this ARTICLE XI.  The Administrative Agent shall not 
have a fiduciary relationship in respect of the Guarantor or any Lender by 
reason of this Agreement.  The Administrative Agent agrees to administer this 
Facility in the same manner as it administers similar facilities for its own 
account.

    XII.2. POWERS.  The Administrative Agent shall have and may exercise such 
powers under the Credit Documents as are specifically delegated to the 
Administrative Agent by the terms of each thereof, together with such powers 
as are reasonably incidental thereto.  The Administrative Agent shall have no 
implied duties to the Lenders, or any obligation to the Lenders to take any 
action thereunder except any action specifically provided by the Credit 
Documents to be taken by the Administrative Agent.

    XII.3. GENERAL IMMUNITY.  Neither the Administrative Agent nor any of its 
directors, officers, agents or employees shall be liable to the Guarantor, 
the Lenders or any Lender for any action taken or omitted to be taken by it 
or them hereunder or under any other Credit Document or in connection 
herewith or therewith except for its or their own gross negligence or willful 
misconduct and except for liability of Administrative Agent for breach of an 
express agreement made by the Administrative Agent herein to take or not take 
actions based on the approval or direction of a requisite number of Lenders.

    XII.4. NO RESPONSIBILITY FOR LOANS, RECITALS, ETC.  Neither the 
Administrative Agent nor any of its directors, officers, agents or employees 
shall be responsible for or have any duty to ascertain, inquire into, or 
verify (i) any statement, warranty or representation made in connection with 
any Credit Document or any borrowing hereunder; (ii) the performance or 
observance of any of the covenants or agreements of any obligor under any 
Credit Document, including, without limitation, any agreement by an obligor 
to furnish information directly to each Lender; (iii) the satisfaction of any 
condition specified in ARTICLE V, except receipt of items required to be 
delivered to the Administrative Agent; (iv) the validity, effectiveness or 
genuineness of any Credit Document or any other instrument or writing 
furnished in connection therewith (provided that Administrative Agent shall 
be obligated to furnish copies of the Credit Documents to the Lenders); or 
(v) the value, sufficiency, creation, perfection or priority of any interest 
in any collateral security. The Administrative Agent shall have no duty to 
disclose to the Lenders information that is not required to be furnished by 
the Guarantor to the Administrative Agent at such time, but is voluntarily 
furnished by the Guarantor to the Administrative Agent in its individual 
capacity.


                                      -75-
<PAGE>

    XII.5. ACTION ON INSTRUCTIONS OF LENDERS.  The Administrative Agent shall 
in all cases be fully protected in acting, or in refraining from acting, 
hereunder and under any other Credit Document in accordance with written 
instructions signed by the Required Lenders unless such action or inaction 
requires the consent of all the Lenders or an individual Lender not included 
in the direction of the Required Lenders pursuant to this Agreement, and such 
instructions and any action taken or failure to act pursuant thereto shall be 
binding on all of the Lenders and on all holders of Notes.  The 
Administrative Agent shall be fully justified in failing or refusing to take 
any action hereunder and under any other Credit Document unless it shall 
first be indemnified to its satisfaction by the Lenders pro rata against any 
and all liability, cost and expense that it may incur by reason of taking or 
continuing to take any such action.

    XII.6. EMPLOYMENT OF ADMINISTRATIVE AGENTS AND COUNSEL.  The 
Administrative Agent may execute any of its duties as Administrative Agent 
hereunder and under any other Credit Document by or through employees, 
agents, and attorneys-in-fact and so long as it exercises reasonable care in 
the selection of such parties, the Administrative Agent shall not be 
answerable to the Lenders, except as to money or securities received by it or 
its authorized agents, for the default or misconduct of any such parties.  
The Administrative Agent shall be entitled to advice of counsel concerning 
all matters pertaining to the agency hereby created and its duties hereunder 
and under any other Credit Document.

    XII.7. RELIANCE ON DOCUMENTS; COUNSEL.  The Administrative 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 
Administrative Agent, which counsel may be employees of the Administrative 
Agent.

    XII.8. ADMINISTRATIVE AGENT'S REIMBURSEMENT AND INDEMNIFICATION.  The 
Lenders agree to reimburse and indemnify the Administrative Agent (in its 
capacity as Administrative Agent but not as Lender) ratably in proportion to 
their respective Commitments (i) for any amounts not reimbursed by the 
Reimbursement Obligor or Guarantor for which the Administrative Agent is 
entitled to reimbursement by the Reimbursement Obligor and Guarantor under 
the Credit Documents including reasonable out-of-pocket expenses in 
connection with the preparation, execution, delivery of the Credit Documents, 
(ii) for any other reasonable out-of-pocket expenses incurred by the 
Administrative Agent on behalf of the Lenders, in connection with the 
administration and enforcement of the Credit Documents 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 Administrative 
Agent in any way relating to or arising out of the Credit Documents or any 
other document delivered in connection therewith or the transactions 
contemplated thereby, or the enforcement of any of the terms thereof or of 
any such other documents, PROVIDED that no Lender shall be liable for any of 
the foregoing to the extent they arise from the gross negligence or willful 
misconduct of the Administrative Agent or an action relating to a dispute 
which is solely between the Administrative Agent and one or more Lenders in 
which the other Lender prevails, or an action taken or not taken by 
Administrative Agent contrary to the express requirements contained herein 
pertaining to the requisite number of Lenders required to approve or direct 
certain actions.  The obligations of the Lenders under this SECTION 12.8 
shall survive payment of the Obligations and termination of this Agreement.

    XII.9. RIGHTS AS A LENDER.

          In the event the Administrative Agent is a Lender, the
Administrative Agent shall have the same rights and powers and the same duties
and obligations hereunder and under any other Credit Document as any Lender and
may exercise the same as though it were not the Administrative Agent, and the
term "LENDER" or "LENDERS" shall, at any time when the Administrative Agent is a
Lender, unless the context otherwise indicates, include the Administrative Agent
in its individual capacity.  The Administrative Agent and any Lender may accept
deposits from, lend money to, and generally engage in any kind of trust, debt,
equity or other transaction, in addition to those contemplated by this Agreement
or any other Credit Document, with the Reimbursement Obligor, Guarantor or any
of their Subsidiaries in which the Reimbursement Obligor, Guarantor or such
Subsidiary is not restricted hereby from engaging with any other Person.


                                      -77-
<PAGE>

    XII.10. LENDER CREDIT DECISION.  Each Lender acknowledges that it has, 
independently and without reliance upon the Administrative Agent, or any 
other Lender and based on the financial statements prepared by the 
Reimbursement Obligor and Guarantor and such other documents and information 
as it has deemed appropriate, made its own credit analysis and decision to 
enter into this Agreement and the other Credit Documents.  Each Lender also 
acknowledges that it will, independently and without reliance upon the 
Administrative Agent, or any other Lender and based on such documents and 
information as it shall deem appropriate at the time, continue to make its 
own credit decisions in taking or not taking action under this Agreement and 
the other Credit Documents.

    XII.11. SUCCESSOR ADMINISTRATIVE AGENT.  The Administrative Agent may 
resign at any time by giving written notice thereof to the Lenders, the 
Reimbursement Obligor and the Guarantor, such resignation in either case to 
be effective upon the appointment of a successor Administrative Agent or, if 
no successor Administrative Agent has been appointed, sixty days after the 
retiring Administrative Agent gives notice of its intention to resign.  Upon 
any such resignation, the Required Lenders shall have the right to appoint 
upon the confirmation of the Guarantor if such successor is not a Lender, on 
behalf of the Guarantor and the Lenders, a successor Administrative Agent.  
If no successor Administrative Agent shall have been so appointed by the 
Required Lenders within forty-five days after the resigning Administrative 
Agent's giving notice of its intention to resign, then the resigning 
Administrative Agent may appoint, on behalf of the Reimbursement Obligor, 
Guarantor and the Lenders, a successor Administrative Agent upon the 
confirmation of the Guarantor (if required).  If the Administrative Agent has 
resigned and no successor Administrative Agent has been appointed and 
confirmed (if required) within 60 days, the Lenders shall perform all the 
duties of the Administrative Agent hereunder and the Guarantor shall make all 
payments in respect of the Obligations to the applicable Lender and for all 
other purposes shall deal directly with the Lenders.  No successor 
Administrative Agent shall be deemed to be appointed hereunder until such 
successor Administrative Agent has accepted the appointment.  Any such 
successor Administrative Agent shall be either a Lender or a commercial bank 
(or a subsidiary thereof) having capital and retained earnings of at least 
$500,000,000 that is generally in the business of making loans comparable to 
the Loans made under this Facility, except that if the successor 
Administrative Agent is a subsidiary of a bank, such capital and retained 
earnings requirement shall apply only to the parent bank.  Upon the 
acceptance of any appointment as Administrative Agent hereunder by a 
successor Administrative Agent, such successor Administrative Agent shall 
thereupon succeed to and become vested with all the rights, powers, 
privileges and duties of the resigning or removed Administrative Agent.  Upon 
the effectiveness of the resignation of the Administrative Agent, the 
resigning Administrative Agent and the successor Administrative Agent shall 
pro rate any agency fees, and the resigning Administrative Agent shall be 
discharged from its duties and obligations hereunder and under the Credit 
Documents.  After the effectiveness of the resignation of an Administrative 
Agent, the provisions of this ARTICLE XI shall continue in effect for the 
benefit of such Administrative Agent in respect of any actions taken or 
omitted to be taken by it while it was acting as the Administrative Agent 
hereunder and under the other Credit Documents.


                                      -78-
<PAGE>

    XII.12. NOTICE OF DEFAULTS.  If a Lender becomes aware of a Default or 
Unmatured Default, such Lender shall notify the Administrative Agent of such 
fact.  Upon receipt of such notice that a Default or Unmatured Default has 
occurred, the Administrative Agent shall notify each of the Lenders of such 
fact.

    XII.13. REQUESTS FOR APPROVAL.  If the Administrative Agent requests in 
writing the consent or approval of a Lender, such Lender shall respond and 
either approve or disapprove definitively in writing to the Administrative 
Agent within ten Business Days (or sooner if such notice specifies a shorter 
period, but in no event less than five Business Days for responses based on 
Administrative Agent's good faith determination that circumstances exist 
warranting its request for an earlier response) after such written request 
from the Administrative Agent.  If the Lender does not so respond, that 
Lender shall be deemed to have approved the request.  Upon request, the 
Administrative Agent shall notify the Lenders which Lenders, if any, failed 
to respond to a request for approval.

    XII.14. COPIES OF DOCUMENTS.  Administrative Agent shall promptly 
deliver to each of the Lenders copies of all notices of default and other 
formal notices sent or received in accordance with SECTION 15 of this 
agreement. Administrative Agent shall deliver to Lenders within 15 Business 
Days following receipt, copies of all financial statements, certificates and 
notices received regarding the Guarantor's unsecured debt rating except to 
the extent such items are required to be furnished directly to the Lenders by 
Guarantor hereunder. Within fifteen Business Days after a request by a Lender 
to the Administrative Agent for other documents furnished to the 
Administrative Agent by the Guarantor, the Administrative Agent shall provide 
copies of such documents to such Lender except where this Agreement obligates 
Administrative Agent to provide copies in a shorter period of time.


                                      -79-

    XII.15. DEFAULTING LENDERS.  At such time as a Lender becomes a 
Defaulting Lender, such Defaulting Lender's right to vote on matters which 
are subject to the consent or approval of the Required Lenders, each affected 
Lender or all Lenders shall be immediately suspended until such time as the 
Lender is no longer a Defaulting Lender.  If a Defaulting Lender has failed 
to fund its Percentage of any amount due from the Lenders hereunder and until 
such time as such Defaulting Lender subsequently funds its Percentage of such 
amount, all Obligations owing to such Defaulting Lender hereunder shall be 
subordinated in right of payment, as provided in the following sentence, to 
the prior payment in full of all principal of, interest on and fees relating 
to the amount funded by the other Lenders for which the Defaulting Lender has 
not funded its Percentage (such principal, interest and fees being referred 
to as "SENIOR LOANS" for the purposes of this section).  All amounts paid by 
the Reimbursement Obligor and otherwise due to be applied to the Obligations 
owing to such Defaulting Lender pursuant to the terms hereof shall be 
distributed by the Administrative Agent to the other Lenders in accordance 
with their respective Percentages (recalculated for the purposes hereof to 
exclude the Defaulting Lender) until all Senior Loans have been paid in full. 
 At that point, the "DEFAULTING LENDER" shall no longer be deemed a 
Defaulting Lender.  After the Senior Loans have been paid in full equitable 
adjustments will be made in connection with future payments by the 
Reimbursement Obligor to the extent a portion of the Senior Loans had been 
repaid with amounts that otherwise would have been distributed to a 
Defaulting Lender but for the operation of this SECTION 12.15.  This 
provision governs only the relationship among the Administrative Agent, each 
Defaulting Lender and the other Lenders; nothing hereunder shall limit the 
obligation of the Reimbursement Obligor to repay all Loans in accordance with 
the terms of this Agreement.  The provisions of this section shall apply and 
be effective regardless of whether a Default occurs and is continuing, and 
notwithstanding (i) any other provision of this Agreement to the contrary, 
(ii) any instruction of the Reimbursement Obligor as to its desired 
application of payments or (iii) the suspension of such Defaulting Lender's 
right to vote on matters which are subject to the consent or approval of the 
Required Lenders or all Lenders.

                                   RATABLE PAYMENTS

                                      -80-
<PAGE>

    XIII.2. RATABLE PAYMENTS.  If any Lender has payment made to it upon its 
Loans (other than payments received pursuant to SECTIONS 4.1, 4.2 or 4.4) in 
a greater proportion than that received by any other Lender, such Lender 
agrees, promptly upon demand, to purchase a portion of the Loans held by the 
other Lenders so that after such purchase each Lender will hold its ratable 
proportion of Loans.  If any Lender, whether in connection with setoff or 
amounts which might be subject to setoff or otherwise, receives collateral or 
other protection for its Obligations or such amounts which may be subject to 
setoff, such Lender agrees, promptly upon demand, to take such action 
necessary such that all Lenders share in the benefits of such collateral 
ratably in proportion to their Loans.  In case any such payment is disturbed 
by legal process, or otherwise, appropriate further adjustments shall be made.

                                     ARTICLE XIV

                  BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS


    XIV.1. SUCCESSORS AND ASSIGNS.  The terms and provisions of the Credit 
Documents shall be binding upon and inure to the benefit of the Reimbursement 
Obligor, Guarantor and the Lenders and their successors and permitted 
assigns, except that (i) the Reimbursement Obligor and Guarantor shall not 
have the right to assign their rights or obligations under the Credit 
Documents and (ii) any assignment by any Lender must be made in compliance 
with SECTION 14.3. Notwithstanding clause (ii) of this SECTION 14.1, any 
Lender may at any time, without the consent of the Reimbursement Obligor or 
Guarantor assign all or any portion of its rights under this Agreement to a 
Federal Reserve Bank; provided, however, that no such assignment shall 
release the transferor Lender from its obligations hereunder.  The 
Administrative Agent may treat a Lender as not having made an assignment or 
transfer unless and until such payee complies with SECTION 14.3 in the case 
of an assignment or, in the case of any other transfer, a written notice of 
the transfer is filed with the Administrative Agent.  Any assignee or 
transferee agrees by acceptance thereof to be bound by all the terms and 
provisions of the Credit Documents.  Any request, authority or consent of any 
Person, who at the time of making such request or giving such authority or 
consent is a Lender, shall be conclusive and binding on any subsequent 
transferee or assignee of such Lender. 

    XIV.2. PARTICIPATIONS.

                                      -81-
<PAGE>

          XIV.2.1.  PERMITTED PARTICIPANTS; EFFECT.  Any Lender, in the
    ordinary course of its business and in accordance with applicable law, at
    any time, may sell participating interests in any Loan owing to such
    Lender, any Commitment of such Lender or any other interest of such Lender
    under the Credit Documents.  Any Person to whom such a participating
    interest is sold is a "PARTICIPANT".  In the event of any such sale by a
    Lender of participating interests to a Participant, such Lender's
    obligations under the Credit Documents shall remain unchanged, such Lender
    shall remain solely responsible to the other parties hereto for the
    performance of such obligations, such Lender shall remain the holder of any
    such Note for all purposes under the Credit Documents, all amounts payable
    by the Reimbursement Obligor under this Agreement shall be determined as if
    such Lender had not sold such participating interests, and the
    Reimbursement Obligor and the Administrative Agent shall continue to deal
    solely and directly with such Lender in connection with such Lender's
    rights and obligations under the Credit Documents.

          XIV.2.2.  VOTING RIGHTS.  Each Lender shall retain the sole right to
    approve, without the consent of any Participant, any amendment,
    modification or waiver of any provision of the Credit Documents other than
    any amendment, modification or waiver with respect to any Loan or
    Commitment in which such Participant has an interest which forgives
    principal, interest or fees or reduces the interest rate or fees payable
    with respect to any such Loan or Commitment or postpones any date fixed for
    any regularly-scheduled payment of principal of, or interest or fees on,
    any such Loan or Commitment or releases any guarantor of any such Loan or
    releases any substantial portion of collateral, if any, securing such Loan.

    XIV.3. ASSIGNMENTS.


                                      -82-
<PAGE>

          XIV.3.1.  PERMITTED ASSIGNMENTS.  Any Lender, in the ordinary course
    of its business and in accordance with applicable law, at any time, may
    assign all or any  portion (greater than or equal to $10,000,000 per
    assignee) of its rights and obligations under the Credit Documents,
    provided that unless such Lender sells its entire interest, it must
    maintain a minimum Commitment of $10,000,000 (exclusive of any portion of
    its Commitment in which it has sold a participation interest other than
    participations where the Lender, Documentation Agent or Administrative
    Agent retains full voting control).  Notwithstanding the foregoing
    provision, any assignment by a Lender to another Lender in the Facility or
    an Affiliate thereof or an Affiliate of the assigning Lender shall not be
    subject to either the $10,000,000 minimum assignment amount or the
    requirement set forth below regarding Reimbursement Obligor's consent or
    the fee in SECTION 14.3.2(ii).  If the Aggregate Commitment is reduced the
    references to $10,000,000 contained in this SECTION 14.3.1 shall be reduced
    proportionately.  Any Person to whom such rights and obligations are
    assigned is a "PURCHASER".  Such assignment shall be substantially in the
    form of EXHIBIT D hereto or in such other form as may be agreed to by the
    parties thereto (the "ASSIGNMENT").  The consent of the Issuing Bank to any
    such assignment shall be required.  So long as no Default has occurred and
    is continuing, Reimbursement Obligor's consent shall also be required for
    any assignment provided that if such assignment is to an entity that is a
    "Qualified Lender", such consent shall not be unreasonably denied or
    delayed.  "QUALIFIED LENDER" shall mean an institution with assets over
    $5,000,000,000.00 that is generally in the business of making loans
    comparable to the Loans made under this Facility and that maintains an
    office in the United States.  Any Lender which is an Arranger,
    Documentation Agent, or Administrative Agent may make an assignment only if
    it first resigns its status as Arranger, Documentation Agent, or
    Administrative Agent as the case may be or if it obtains the consent of
    Reimbursement Obligor and any Lender which after such assignment would have
    a Percentage greater than the new Percentage of the Lender making the
    assignment.  Notwithstanding any other provision set forth in this
    Agreement, any Lender may at any time create a security interest in all or
    any portion of its rights under this Agreement (including, without
    limitation, amounts owing to it in favor of any Federal Reserve Bank in
    accordance with Regulation A of the Board of Governors of the Federal
    Reserve System), provided that no such security interest or the exercise by
    the secured party of any of its rights thereunder shall release Lender from
    its funding obligations hereunder and such Lender shall retain all voting
    rights.

<PAGE>

          XIV.3.2.  EFFECT; EFFECTIVE DATE.  Upon (i) delivery to the
    Administrative Agent and the Reimbursement Obligor of a notice of
    assignment, substantially in the form attached as EXHIBIT I to EXHIBIT D
    hereto (a "NOTICE OF ASSIGNMENT"), together with any consents required by
    SECTION 14.3.1, and (ii) payment of a $3,000 fee to the Administrative
    Agent for processing such assignment, such assignment shall become
    effective on the effective date specified in such Notice of Assignment. 
    The Notice of Assignment shall contain a representation by the Purchaser to
    the effect that none of the consideration used to make the purchase of the
    Commitment and Loans under the applicable assignment agreement are "plan
    assets" as defined under ERISA and that the rights and interests of the
    Purchaser in and under the Credit Documents will not be "plan assets" under
    ERISA.  On and after the effective date of such assignment, such Purchaser
    shall for all purposes be a Lender party to this Agreement and any other
    Credit Document executed by the Lenders and shall have all the rights and
    obligations of a Lender under the Credit Documents, to the same extent as
    if it were an original party hereto, and no further consent or action by
    the Guarantor, the Lenders or the Administrative Agent shall be required to
    release the transferor Lender with respect to the percentage of the
    Aggregate Commitment and Loans assigned to such Purchaser.  

    XIV.4. DISSEMINATION OF INFORMATION.  The Reimbursement Obligor 
authorizes each Lender to disclose to any Participant or Purchaser or any 
other Person acquiring an interest in the Credit Documents by operation of 
law (each a "TRANSFEREE") and any prospective Transferee any and all 
information in such Lender's possession concerning the creditworthiness of 
the Reimbursement Obligor, Guarantor and their Subsidiaries, provided that 
such Transferees agree to maintain the confidentiality of any information 
that is confidential in the manner set forth in SECTION 11.14.

    XIV.5. TAX TREATMENT.  If any interest in any Credit Document is 
transferred to any Transferee which is organized under the laws of any 
jurisdiction other than the United States or any State thereof, the 
transferor Lender shall cause such Transferee, concurrently with the 
effectiveness of such transfer, to comply with the provisions of SECTION 2.17.

    XIV.6. POSSESSION OF CREDIT DOCUMENTS AND REGISTER.  The Administrative 
Agent shall keep and maintain complete and accurate files and records of all 
matters pertaining to the Facility.  Upon reasonable prior notice to the 
Administrative Agent by any Lender, the Administrative Agent will make 
available to such Lender and their representatives and agents, the files and 
records relating to the Facility for inspection and copying during normal 
business hours.  The Administrative Agent shall also maintain at its address 
specified pursuant to Article XV, a copy of each Assignment delivered to and 
accepted by it and a listing of the names and addresses of the Lenders, the 
amount of each Lender's Commitment and Percentage (the "REGISTER").  The 
entries in the Register shall be conclusive and binding for all purposes, 
absent manifest error, and the Reimbursement Obligor, Administrative Agent, 
and the Lenders may treat each person or entity whose name is recorded in the 
Register as a Lender hereunder for all purposes of this Agreement.  The 
Register shall be available for inspection and copying by the Reimbursement 
Obligor or any Lender during normal business hours upon reasonable prior 
notice to the Administrative Agent.

party at its address set forth below its signature hereto or at such other 
address as may be designated by such party in a notice to the other parties.  
Any notice, if mailed and properly addressed with postage prepaid, shall be 
deemed given when received; any notice, if transmitted by telex or facsimile, 
shall be deemed given when transmitted (answerback confirmed in the case of 
telexes).

    XV.2. CHANGE OF ADDRESS.  Any of the parties to this Agreement may change 
the address for service of notice upon it by a notice in writing to the other

*   In basis points per annum. 
**  Commencing October 23, 1998, this rating category will be deemed to apply
    if the Guarantor does not have a rating of at least BBB- from S&P and a
    rating of at least Baa3 from Moody's (or an alternate agency to the extent
    provided below).  This rating category shall also apply at any time that
    either S&P has issued a rating of less than BBB- or Moody's has issued a
    rating of less than Baa3, or either S&P or Moody's has withdrawn its
    rating.

All margins and fees change as and when the rating classification of the 
Guarantor changes.  In the event the rating agencies are split on the rating for
the Guarantor, the lower rating shall be deemed to be the applicable rating.  In
the event either rating agency has not issued a rating, the rating from the
agency that has issued its rating shall govern subject to the provisions above
regarding the time by which certain ratings must be obtained.

In the event of a rating agency downgrade, the Reimbursement Obligor will
receive a credit for any incremental borrowing cost should the rating
agency(ies) restore the higher rating within a ninety day period.  In the event
that either S & P or Moody shall cease to follow the REIT industry, an alternate
agency will be selected that is mutually acceptable to the Required Lenders and
the Reimbursement Obligor.

                                   FORM OF OPINION

                                                     ______________ , 19__

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

Gentlemen/Ladies:

    We are counsel for CenterPoint O'Hare, L.L.C. ("REIMBURSEMENT OBLIGOR")
CenterPoint Properties Corporation (the "GUARANTOR"), and have represented the
Reimbursement Obligor and Guarantor in connection with their execution and
delivery of an Credit and Reimbursement Agreement among the Reimbursement
Obligor, Guarantor, The First National Bank of Chicago, individually and as
Administrative Agent, and the Lenders named therein, dated as of
__________________, 1997, providing for issuance of a Letter of Credit in the
amount of _____________ (the "AGREEMENT").  All capitalized terms used in this
opinion and not otherwise defined shall have the meanings attributed to them in
the Agreement.

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

    l.    The Reimbursement Obligor, Guarantor and each of their Subsidiaries
and each Qualifying Investment Affiliate are either duly incorporated
corporations or duly qualified and formed limited partnerships or limited
liability companies, validly existing and in good standing under the laws of
their states of incorporation or formation, and they each have all requisite
authority and power to enter into, and perform the obligations under, the Credit
Documents and to conduct business in each jurisdiction in which they conduct
business. 

    2.    The execution and delivery of the Credit Documents by the Guarantor
and Reimbursement Obligor and the performance by the Guarantor and Reimbursement
Obligor of their obligations under the Credit Documents have been duly
authorized by all necessary action and/or proceedings on the part of the
Guarantor and Reimbursement Obligor and will not:

          (a) require any consent of the shareholders of Guarantor or
    members of the Reimbursement Obligor;

          (b) violate any law, rule, regulation, order, writ, judgment,
    injunction, decree or award binding on the Reimbursement Obligor, Guarantor
    or any of its 

<PAGE>

    Subsidiaries or the Reimbursement Obligor's, Guarantor's or any 
    Subsidiary's articles of incorporation, by-laws, certificate of limited
    partnership, partnership agreement, operating agreement or any indenture,
    instrument or agreement binding upon the Reimbursement Obligor, Guarantor
    or any of its Subsidiaries; or

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

    3.    The Credit Documents have been duly executed and delivered by the
Reimbursement Obligor and Guarantor and constitute legal, valid and binding
obligations of the Reimbursement Obligor and Guarantor enforceable in accordance
with their terms except to the extent the enforcement thereof may be limited by
bankruptcy, insolvency or similar laws affecting the enforcement of creditors'
rights generally and subject also to the availability of equitable remedies if
equitable remedies are sought.

    4.    There is no litigation or proceeding against the Reimbursement
Obligor, Guarantor or any of their Subsidiaries which, if adversely determined,
could have a Material Adverse Effect.

    5.    No approval, authorization, consent, adjudication or order of, or
registration or filing with, any governmental authority, which has not been
obtained or made by the Reimbursement Obligor, Guarantor or any of their
Subsidiaries, is required to be obtained or made by the Reimbursement Obligor,
Guarantor or any of their Subsidiaries in connection with the execution and
delivery of the Credit Documents, the borrowings under the Agreement or in
connection with the payment by the Reimbursement Obligor or Guarantor of their
obligations under the Credit Documents.

    6.    The Loan does not violate the usury laws or laws regulating the use
or forbearance of money of Illinois and the operation of any term of the
Agreement or Credit Documents, including, without limitation, the terms
regarding late charges and default interest rate or the lawful exercise of any
right thereunder, shall not render the Agreement or Credit Documents
unenforceable, in whole or in part, or subject to any right of rescission,
set-off, counterclaim or defense.

    7.    The Guarantor qualifies as a real estate investment trust in
accordance with all applicable requirements of the Internal Revenue Code.

    This opinion may be relied upon by the Administrative Agent, the Lenders
and their participants, assignees and other transferees.

                             Very truly yours,


                             -----------------------------

                                COMPLIANCE CERTIFICATE



To: The Administrative Agent and the Lenders 
    who are parties to the Agreement described below

    This Compliance Certificate is furnished pursuant to that certain Credit 
and Reimbursement Agreement, dated as of __________, 1997 (as amended, 
modified, renewed or extended from time to time, the "AGREEMENT") among 
CenterPoint O'Hare, L.L.C. ("REIMBURSEMENT OBLIGOR"), CenterPoint Properties 
Corporation (the "GUARANTOR"), The First National Bank of Chicago, 
individually and as Administrative Agent, and the Lenders named therein.  
Unless otherwise defined herein, capitalized terms used in this Compliance 
Certificate have the meanings ascribed thereto in the Agreement.

    THE UNDERSIGNED HEREBY CERTIFIES THAT:

    1.  I am the duly elected Chief Financial Officer of the Guarantor.

    2.  I have reviewed the terms of the Agreement and I have made, or have 
caused to be made under my supervision, a detailed review of the transactions 
and conditions of the Guarantor and its Subsidiaries and Qualifying 
Investment Affiliates during the accounting period covered by the financial 
statements attached (or most recently delivered to the Administrative Agent 
if none are attached).

    3.  The examinations described in paragraph 2 did not disclose, and I 
have no knowledge of, the existence of any condition or event which 
constitutes a Material Adverse Effect, Default or Unmatured Default during or 
at the end of the accounting period covered by the attached financial 
statements or as of the date of this Compliance Certificate, except as set 
forth below.

    4.  Schedule I (if attached) attached hereto sets forth financial data 
and computations and other information evidencing the Guarantor's compliance 
with certain covenants of the Agreement, all of which data, computations and 
information (or if no Schedule I is attached, the data, computations and 
information contained in the most recent Schedule I attached to a prior 
Compliance Certificate) are true, complete and correct in all material 
respects.

    5. The financial statements and reports referred to in SECTION 8.1(i),

                                 EXHIBIT D

                            ASSIGNMENT AGREEMENT

    This Assignment Agreement (this "ASSIGNMENT AGREEMENT") between
                           (the "ASSIGNOR") and                   
(the "ASSIGNEE") is dated as of                  , 19  .  The parties
hereto agree as follows:

    1.    PRELIMINARY STATEMENT.  The Assignor is a party to an
Credit and Reimbursement Agreement (which, as it may be amended,
modified, renewed or extended from time to time is herein called the
"CREDIT AGREEMENT") described in Item 1 of Schedule 1 attached hereto
("SCHEDULE 1").  Capitalized terms used herein and not otherwise
defined herein shall have the meanings attributed to them in the
Credit Agreement.

    2.    ASSIGNMENT AND ASSUMPTION.  The Assignor hereby sells and
assigns to the Assignee, and the Assignee hereby purchases and assumes
from the Assignor, an interest in and to the Assignor's rights and
obligations under the Credit Agreement such that after giving effect
to such assignment the Assignee shall have purchased pursuant to this
Assignment Agreement the percentage interest specified in Item 3 of
Schedule 1 of all outstanding rights and obligations under the Credit
Agreement and the other Credit Documents.  The aggregate Commitment
(or Loans, if the applicable Commitment has been terminated) purchased
by the Assignee hereunder is set forth in Item 4 of Schedule 1.

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

    4.    PAYMENTS OBLIGATIONS.  On and after the Effective Date,
the Assignee shall be entitled to receive from the Administrative
Agent all payments of principal, interest and fees with respect to the
interest assigned hereby.  The Assignee shall advance funds directly
to the Administrative Agent with respect to all Loans and
reimbursement payments made on or after the Effective Date with
respect to the interest assigned hereby.  [In consideration for the
sale and assignment of Loans hereunder, (i) the Assignee shall pay the
Assignor, on the Effective Date, an amount equal to the principal
amount of the portion of all 

<PAGE>

CBR Loans assigned to the Assignee hereunder and (ii) with respect to each 
LIBOR Loan made by the Assignor and assigned to the Assignee hereunder which 
is outstanding on the Effective Date, (a) on the last day of the Interest 
Period therefor or (b) on such earlier date agreed to by the Assignor and the 
Assignee or (c) on the date on which any such LIBOR Loan either becomes due 
(by acceleration or otherwise) or is prepaid (the date as described in the 
foregoing clauses (a), (b) or (c) being hereinafter referred to as the "LIBOR 
DUE DATE"), the Assignee shall pay the Assignor an amount equal to the 
principal amount of the portion of such LIBOR Loan assigned to the Assignee 
which is outstanding on the LIBOR Due Date.  If the Assignor and the Assignee 
agree that the applicable LIBOR Due Date for such LIBOR Loan shall be the 
Effective Date, they shall agree, solely for purposes of dividing interest 
paid by the Guarantor on such LIBOR Loan, to an alternate interest rate 
applicable to the portion of such Loan assigned hereunder for the period from 
the Effective Date to the end of the related Interest Period (the "AGREED 
INTEREST RATE") and any interest received by the Assignee in excess of the 
Agreed Interest Rate, with respect to such LIBOR Loan for such period, shall 
be remitted to the Assignor.  In the event a prepayment of any LIBOR Loan 
which is existing on the Effective Date and assigned by the Assignor to the 
Assignee hereunder occurs after the Effective Date but before the applicable 
LIBOR Due Date, the Assignee shall remit to the Assignor any excess of the 
funding indemnification amount paid by the Guarantor under SECTION 3.4 of the 
Credit Agreement an account of such prepayment with respect to the portion of 
such LIBOR Loan assigned to the Assignee hereunder over the amount which 
would have been paid if such prepayment amount were calculated based on the 
Agreed Interest Rate and only covered the portion of the Interest Period 
after the Effective Date.  The Assignee will promptly remit to the Assignor 
(i) the portion of any principal payments assigned hereunder and received 
from the Administrative Agent with respect to any LIBOR Loan prior to its 
LIBOR Due Date and (ii) any amounts of interest on Loans and fees received 
from the Administrative Agent which relate to the portion of the Loans 
assigned to the Assignee hereunder for periods prior to the Effective Date, 
in the case of CBR Loans or fees, or the LIBOR Due Date, in the case of LIBOR 
Loans, and not previously paid by the Assignee to the Assignor.]*  In the 
event that either party hereto receives any payment to which the other party 
hereto is entitled under this Assignment Agreement, then the party receiving 
such amount shall promptly remit it to the other party hereto.

    5.    FEES PAYABLE BY THE ASSIGNEE.  The Assignee shall pay to
the Assignor a fee on each day on which a payment of interest or
Commitment Fees is made under the Credit Agreement with respect to the
amounts assigned to the Assignee hereunder (other than a payment of
interest or Commitment Fees attributable to the period prior to the
Effective Date or, in the case of LIBOR Loans, the Payment Date, which
the Assignee is obligated to deliver to the Assignor pursuant to
SECTION 4 hereof).  The amount of such fee shall be the difference
between (i) the interest or fee, as applicable, paid with respect to
the amounts assigned to the Assignee hereunder and (ii) the interest
or fee, as applicable, which would have been paid with respect to the
amounts assigned to the Assignee hereunder if each interest rate was
calculated at the rate of    % rather than the actual percentage used
to calculate the interest rate paid by the Guarantor or if the
Commitment Fee was calculated at the rate of    % rather than the
actual percentage used to calculate the Commitment Fee paid by the
Guarantor, 


                                      -2-

as applicable.  In addition, the Assignee agrees to pay ___% of the fee

From:  [NAME OF ASSIGNOR] (the "ASSIGNOR")

       [NAME OF ASSIGNEE] (the "ASSIGNEE")


          1.  We refer to that Credit and Reimbursement Agreement (the
"CREDIT AGREEMENT") described in Item 1 of Schedule 1 attached hereto
("SCHEDULE 1").  Capitalized terms used herein and not otherwise defined
herein shall have the meanings attributed to them in the Credit Agreement.

          2.  This Notice of Assignment (this "NOTICE") is given and
delivered to the Administrative Agent pursuant to SECTION 13.3.2 of the

          3.  The Assignor and the Assignee have entered into an
Assignment Agreement, dated as of             , 19   (the "ASSIGNMENT"),
pursuant to which, among other things, the Assignor has sold, assigned,
delegated and transferred to the Assignee, and the Assignee has purchased,
accepted and assumed from the Assignor the percentage interest specified in
Item 3 of Schedule 1 of all outstandings, rights and obligations under the
Credit Agreement.  From and after such purchase, the Assignee's Commitment
shall be the amount specified in Item 4 of Schedule 1 and the Assignor's
Commitment shall be the amount specified in Item 5 of Schedule 1.  The
Effective Date of the Assignment shall be the later of the date specified
in Item 5 of Schedule 1 or two (2) Business Days (or such shorter period as
agreed to by the Administrative Agent) after this Notice of Assignment and
any fee required by SECTION 13.3.2 of the Credit Agreement have been
delivered to the Administrative Agent, provided that the Effective Date
shall not occur if any condition precedent agreed to by the Assignor and
the Assignee or set forth in SECTION 13 of the Credit Agreement has not
been satisfied.

          4.  The Assignor and the Assignee hereby give to the
Administrative Agent notice of the assignment and delegation referred to
herein.  The Assignor will confer with the Administrative Agent before the

effective on such date pursuant to SECTION 3 hereof, and will confer with the 
Administrative Agent to determine the Effective Date pursuant to SECTION 3 
hereof if it occurs thereafter.  The Assignor shall notify the Administrative 
Agent if the Assignment Agreement does not become effective on any proposed 
Effective Date as a result of the failure to satisfy the conditions precedent 
agreed to by the Assignor and the Assignee.   At the request of the 
Administrative Agent, the Assignor will give the Administrative Agent written 
confirmation of the satisfaction of the conditions precedent.

          5.  The Assignor or the Assignee shall pay to the Administrative
Agent on or before the Effective Date the processing fee of $3,000 required
by SECTION 13.3.2 of the Credit Agreement.

          6.  If Notes are outstanding on the Effective Date, the Assignor
and the Assignee request and direct that the Administrative Agent prepare
and cause the Guarantor to execute and deliver new Notes or, as
appropriate, replacements notes, to the Assignor and the Assignee.  The
Assignor and, if applicable, the Assignee each agree to deliver to the
Administrative Agent the original Note received by it from the Guarantor
upon its receipt of a new Note in the appropriate amount.

          7.  The Assignee advises the Administrative Agent that notice
and payment instructions are set forth in the attachment to Schedule 1.

          8.  The Assignee hereby represents and warrants that none of the
funds, monies, assets or other consideration being used to make the
purchase pursuant to the Assignment are "plan assets" as defined under
ERISA and that its rights, benefits, and interests in and under the Credit
Documents will not be "plan assets" under ERISA.

          9.  The Assignee authorizes the Administrative Agent to act as
its agent under the Credit Documents in accordance with the terms thereof. 
The Assignee acknowledges that the Administrative Agent has no duty to
supply information with respect to the Guarantor or the Credit Documents to
the Assignee until the Assignee becomes a party to the Credit Agreement.*

*May be eliminated if Assignee is a party to the Credit Agreement prior to
the Effective Date.

             MINIMUM SPECIFICATIONS FOR ENVIRONMENTAL INVESTIGATIONS

    The following are Guidelines for the qualification of firms and
environmental professionals and for information to be included in
Environmental Site Assessments.  These standards include the minimum
elements common to acceptable site assessments.  Generally, it is intended
for the standards to be consistent with those outlined in the American
Society for Testing and Materials ("ASTM") Designation:  E 1527-93.

QUALIFICATIONS OF INVESTIGATING FIRM

    The firm or environmental professional must have 5 years of experience
in hazardous substances investigation.  The environmental professional
supervising and signing the report should be experienced in environmental
site investigations, and should have relevant environmental experience and
technical qualifications, such as demonstrated by professional registration
and/or advanced education in related disciplines.  The firm or
environmental professional performing the work should have adequate
professional liability insurance.  Guarantor and Lenders may agree in
advance on qualified firms or environmental professionals that will conduct
the Phase I Reports.  Guarantor may from time to time select other firms or
environmental professionals that meet the minimum qualifications set out
above to conduct a Phase I Report, subject to approval of the
Administrative Agent, which approval shall not be unreasonably withheld or
delayed.


<PAGE>

DEPTH OF REPORTING REQUIRED

    Phase I - consists of site description, review of historical and
regulatory data and physical inspection.  The firm or environmental
professional will follow the standard practices set out in the
ASTM E 1527-93 guidelines in conducting the Phase I Site Assessment and
drafting the Report and in preparing the Findings and Conclusions.  All
deletions and deviations from the ASTM E 1527-93 guidelines shall be listed
individually and in detail.  As an additional component of the Phase I Site
Assessment, the firm or environmental professional will conduct an asbestos
survey or inspection in accordance with the protocols set by OSHA under the
Occupational Safety & Health Act (including protocols set forth under the
Asbestos Hazard Emergency Response Act (AHERA) that are incorporated into
the OSHA protocols) unless an alternate protocol is approved by the
Administrative Agent.  In all events such survey or inspection shall comply
with all applicable Environmental Laws, including, but not limited to, 29
C.F.R. Section  1910.1001.  The firm or environmental professional will
also conduct a lead-based paint survey or inspection when necessary,
including but not limited to prior to demolition or renovation work and as
required by all applicable Environmental Laws, including, but not limited
to 29 C.F.R. Sections  1910.1025 and 1926.62.  If no potential
contamination is indicated, the report should so state, and a specific
statement should be made that no further investigation is required.

    Phase II - If a Phase I examination indicates the presence of
recognized environmental conditions which would warrant further appropriate
inquiry, the consultant should document the basis for that conclusion,
recommend a testing program for further evaluation, including the areas to
be tested and, if appropriate, the hazardous constituents of concern,
sampling procedures to be used and methods used to assess the samples.  If
after evaluating the recommendation, the Guarantor determines that a Phase
II is necessary, then the Guarantor will request the firm or environmental
professional to prepare a bid, and may 

                                      -2-
<PAGE>

solicit competitive bids from other firms or environmental professionals.  
The Phase II Report should document the extent, and, if possible, source, of 
contamination so that the Guarantor can assess whether remediation is 
required under applicable Environmental Laws.  If the Guarantor plans to 
conduct remediation estimated to cost more than $250,000 for any Project, the 
Guarantor will promptly provide written notice to the Administrative Agent.  
If the Guarantor does not follow the recommendation of the firm or 
environmental professional to conduct a Phase II investigation or remediation 
for any Project, the Guarantor will promptly provide written notice to the 
Administrative Agent.

RELIANCE ON PHASE I REPORT

    The Phase I Report shall include a statement that the firm or
environmental professional acknowledges that the Lenders will be relying on
the Report.

                                       GUARANTY


    This Guaranty is made as of September 1, 1997, by CenterPoint Properties 
Corporation, a Maryland corporation (the "GUARANTOR"), to and for the benefit 
of The First National Bank of Chicago, individually ("FNBC") and as 
administrative agent (the "AGENT") for itself and the lenders under the 
Credit and Reimbursement Agreement (as defined below) and their respective 
successors and assigns (collectively, the "LENDERS").

                                       RECITALS

    A.   CenterPoint O'Hare, L.L.C., an Illinois limited liability company 
("Reimbursement Obligor"), and the Guarantor have requested that the Lenders 
make available a credit facility to the Reimbursement Obligor in the amount 
of $55,813,699 for the purpose of providing credit enhancement for certain 
bonds as is more fully described in the Credit Agreement described below.

    B.   The Lenders have agreed to make available the Facility to the 
Reimbursement Obligor pursuant to the terms and conditions set forth in a 
Credit and Reimbursement Agreement of even date herewith between the 
Reimbursement Obligor, the Guarantor, FNBC, individually, and as 
Administrative Agent, and the Lenders named therein (as amended, modified or 
restated from time to time, the "CREDIT AGREEMENT").  All capitalized terms 
used herein and not otherwise defined shall have the meanings ascribed to 
such terms in the Credit Agreement.

    C.   The Guarantor is the manager and owner of 95% of the membership 
interest of the Reimbursement Obligor and, therefore, the Guarantor will 
derive financial benefit from the Facility.  The execution and delivery of 
this Guaranty by the Guarantor is a condition precedent to the performance by 
the Lenders of their obligations under the Credit Agreement.

                                      AGREEMENTS

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

1.  The Guarantor absolutely, unconditionally, and irrevocably guarantees to 
each of the Lenders:

         (a)  the full and prompt payment of all unpaid, outstanding amounts
    which may now be or may hereafter become due and owing to Agent and Lenders
    under the Credit Agreement and any other Credit Documents, whether at
    stated maturity, upon acceleration or otherwise, and at all times
    thereafter;
<PAGE>

         (b)  the payment of all Enforcement Costs (as hereinafter defined in
    PARAGRAPH 7 hereof); and

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

All amounts due, debts, liabilities, and payment obligations described in 
subparagraphs (a) and (b) of this PARAGRAPH 1 are referred to herein as the 
"FACILITY INDEBTEDNESS."  All obligations described in subparagraph (c) of 
this PARAGRAPH 1 are referred to herein as the "OBLIGATIONS."

2.  Upon the occurrence of a Default, the Guarantor agrees, on written demand 
by the Agent, to pay all the Facility Indebtedness and to perform all the 
Obligations as are then or thereafter become due and owing or are to be 
performed under the terms of the Credit Agreement and the other Credit 
Documents.

3.  The Guarantor does hereby waive (i) notice of acceptance of this Guaranty 
by the Agent and the Lenders and any and all notices and demands of every 
kind which may be required to be given by any statute, rule or law, (ii) any 
defense, right of set-off or other claim which the Guarantor may have against 
the Reimbursement Obligor or which the Guarantor or the Reimbursement Obligor 
may have against the Agent or the Lenders, (iii) presentment for payment, 
demand for payment (other than as provided for in PARAGRAPH 2 above), notice 
of nonpayment (other than as provided for in PARAGRAPH 2 above) or dishonor, 
protest and notice of protest, diligence in collection and any and all 
formalities which otherwise might be legally required to charge the Guarantor 
with liability, (iv) any failure by the Agent and the Lenders to inform the 
Guarantor of any facts the Agent and the Lenders may now or hereafter know 
about the Reimbursement Obligor, the Facility, or the transactions 
contemplated by the Credit Agreement, it being understood and agreed that the 
Agent and the Lenders have no duty so to inform and that the Guarantor is 
fully responsible for being and remaining informed by the Reimbursement 
Obligor of all circumstances bearing on the existence or creation, or the 
risk of nonpayment of the Facility Indebtedness or the risk of nonperformance 
of the Obligations, and (v) any and all right to cause a marshalling of 
assets of the Reimbursement Obligor or any other action by any court or 
governmental body with respect thereto, or to cause the Agent and the Lenders 
to proceed against any other security given to a Lender in connection with 
the Facility Indebtedness or the Obligations.  Credit may be granted or 
continued from time to time by the Lenders to the Reimbursement Obligor 
without notice to or authorization from the Guarantor, regardless of the 
financial or other condition of the Reimbursement Obligor at the time of any 
such grant or continuation.  The Agent and the Lenders shall have no 
obligation to disclose or discuss with the Guarantor their assessment of the 
financial condition of the Reimbursement Obligor.  The Guarantor acknowledges 
that no representations of any kind whatsoever have been made by the Agent 
and the Lenders to the Guarantor.  No modification or waiver of any of the 
provisions of this Guaranty shall be binding upon the Agent and the Lenders 
except as expressly set forth in a writing duly signed and delivered on 
behalf of the Agent and the Lenders.


                                      -2-
<PAGE>

4.  The Guarantor further agrees that Guarantor's liability as guarantor 
shall in no way be impaired by any renewals or extensions which may be made 
from time to time, with or without the knowledge or consent of the Guarantor 
of the time for payment of any Facility Indebtedness or by any waiver by the 
Agent and the Lenders under the Credit Agreement, or any other Credit 
Documents, or by the Agent or the Lenders' failure or election not to pursue 
any other remedies they may have against the Reimbursement Obligor, or by any 
change or modification in the Credit Agreement, the Letter of Credit 
(including any extension of the term of the Letter of Credit) or any other 
Credit Documents, or by the acceptance by the Agent or the Lenders of any 
security or any increase, substitution or change therein, or by the release 
by the Agent and the Lenders of any security or any withdrawal thereof or 
decrease therein, or by the application of payments received from any source 
to the payment of any obligation of the Reimbursement Obligor other than the 
Facility Indebtedness, even though a Lender might lawfully have elected to 
apply such payments to any part or all of the Facility Indebtedness, it being 
the intent hereof that Guarantor shall remain liable as principal for payment 
of the Facility Indebtedness and performance of the Obligations until all 
indebtedness has been paid in full and the other terms, covenants and 
conditions of the Credit Agreement, and other Credit Documents and this 
Guaranty have been performed, notwithstanding any act or thing which might 
otherwise operate as a legal or equitable discharge of a surety.  The 
Guarantor further understands and agrees that the Agent and the Lenders may 
at any time enter into agreements with the Reimbursement Obligor to amend and 
modify the Credit Agreement or any of the other Credit Documents, or any 
thereof, and may waive or release any provision or provisions of the Credit 
Agreement, or any other Credit Document and, with reference to such 
instruments, may make and enter into any such agreement or agreements as the 
Agent, the Lenders and the Reimbursement Obligor may deem proper and 
desirable, without in any manner impairing this Guaranty or any of the Agent 
and the Lenders' rights hereunder or any of the Guarantor's obligations 
hereunder.

5.  This is an absolute, unconditional, complete, present and continuing 
guaranty of payment and performance and not of collection.  The Guarantor 
agrees that this Guaranty may be enforced by the Agent and the Lenders 
without the necessity at any time of resorting to or exhausting any security 
or collateral, if any, given in connection herewith or with the Credit 
Agreement, or any of the other Credit Documents or by or resorting to any 
other guaranties, and the Guarantor hereby waives the right to require the 
Agent and the Lenders to join the Reimbursement Obligor in any action brought 
hereunder or to commence any action against or obtain any judgment against 
the Reimbursement Obligor or to pursue any other remedy or enforce any other 
right.  The Guarantor further agrees that nothing contained herein or 
otherwise shall prevent the Agent and the Lenders from pursuing concurrently 
or successively all rights and remedies available to them at law and/or in 
equity or under the Credit Agreement or any other Credit Documents, and the 
exercise of any of their rights or the completion of any of their remedies 
shall not constitute a discharge of any of the Guarantor's obligations 
hereunder, it being the purpose and intent of the Guarantor that the 
obligations of such Guarantor hereunder shall be primary, absolute, 
independent and unconditional under any and all circumstances whatsoever.  
Neither the Guarantor's obligations under this Guaranty 


                                      -3-
<PAGE>

nor any remedy for the enforcement thereof shall be impaired, modified, 
changed or released in any manner whatsoever by any impairment, modification, 
change, release or limitation of the liability of the Reimbursement Obligor 
under the Credit Agreement (except to the extent the Reimbursement Obligor's 
liability is limited under Section 11.7 of the Credit Agreement) or any other 
Credit Document or by reason of the Reimbursement Obligor's bankruptcy or by 
reason of any creditor or bankruptcy proceeding instituted by or against the 
Reimbursement Obligor.  This Guaranty shall continue to be effective and be 
deemed to have continued in existence or be reinstated (as the case may be) 
if at any time payment of all or any part of any sum payable pursuant to the 
Credit Agreement or any other Credit Document is rescinded or otherwise 
required to be returned by the payee upon the insolvency, bankruptcy, or 
reorganization of the payor, all as though such payment to such Lender had 
not been made, regardless of whether such Lender contested the order 
requiring the return of such payment. The obligations of the Guarantor 
pursuant to the preceding sentence shall survive any termination, 
cancellation, or release of this Guaranty.

6.  This Guaranty shall be assignable by a Lender to any permitted assignee of
all or a portion of such Lender's rights under the Credit Documents.

7.  If:  (i) this Guaranty, or any of the Credit Documents are placed in the 
hands of an attorney for collection or is collected through any legal 
proceeding; (ii) an attorney is retained to represent the Agent or any Lender 
in any bankruptcy, reorganization, receivership, or other proceedings 
affecting creditors' rights and involving a claim under this Guaranty, the 
Credit Agreement, or any Credit Document; (iii) an attorney is retained to 
enforce any of the other Credit Documents or to provide advice or other 
representation with respect to the Credit Documents in connection with an 
enforcement action or potential enforcement action; or (iv) an attorney is 
retained to represent the Agent or any Lender in any other legal proceedings 
whatsoever in connection with this Guaranty, the Credit Agreement, any of the 
Credit Documents, or any property subject thereto (other than any action or 
proceeding brought by any Lender or participant against the Agent alleging a 
breach by the Agent of its duties under the Credit Documents), then the 
Guarantor shall pay to the Agent or such Lender upon demand all reasonable 
attorney's fees, costs and expenses, including, without limitation, court 
costs, filing fees and all other costs and expenses reasonably incurred in 
connection therewith (all of which are referred to herein as "ENFORCEMENT 
COSTS"), in addition to all other amounts due hereunder.

8.  The parties hereto intend that each provision in this Guaranty comports 
with all applicable local, state and federal laws and judicial decisions.  
However, if any provision or provisions, or if any portion of any provision 
or provisions, in this Guaranty is found by a court of law to be in violation 
of any applicable local, state or federal ordinance, statute, law, 
administrative or judicial decision, or public policy, and if such court 
should declare such portion, provision or provisions of this Guaranty to be 
illegal, invalid, unlawful, void or 


                                      -4-
<PAGE>

unenforceable as written, then it is the intent of all parties hereto that 
such portion, provision or provisions shall be given force to the fullest 
possible extent that they are legal, valid and enforceable, that the 
remainder of this Guaranty shall be construed as if such illegal, invalid, 
unlawful, void or unenforceable portion, provision or provisions were not 
contained therein, and that the rights, obligations and interest of the Agent 
and the Lender or the holder of a NOTE under the remainder of this Guaranty 
shall continue in full force and effect.

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

10.  The Guarantor waives and releases any claim (within the meaning of 11 
U.S.C. Section  101) which the Guarantor may have against the Reimbursement 
Obligor arising from a payment made by the Guarantor under this Guaranty and 
agrees not to assert or take advantage of any subrogation rights of the 
Guarantor or the Lenders or any right of the Guarantor or the Lenders to 
proceed against (i) the Reimbursement Obligor for reimbursement, or (ii) any 
other guarantor or any collateral security or guaranty or right of offset 
held by the Lenders for the payment of the Facility Indebtedness and 
performance of the Obligations, nor shall the Guarantor seek or be entitled 
to seek any contribution or reimbursement from the Reimbursement Obligor or 
any other guarantor in respect of payments made by the Guarantor hereunder 
unless and until the Facility Indebtedness is paid in full.  It is expressly 
understood that the waivers and agreements of the Guarantor set forth above 
constitute additional and cumulative benefits given to the Lenders for their 
security and as an inducement for their extension of credit to the 
Reimbursement Obligor. Nothing contained in this Paragraph 10 is intended to 
prohibit the Guarantor from making all distributions to its constituent 
shareholders which are required by law from time to time in order for the 
Guarantor to maintain its status as a real estate investment trust in 
compliance with all applicable provisions of the Code.

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

12.  The Guarantor hereby submits to personal jurisdiction in the State of 
Illinois for the enforcement of this Guaranty and waives any and all personal 
rights to object to such jurisdiction for the purposes of litigation to 
enforce this Guaranty.  The Guarantor hereby consents to the jurisdiction of 
either the Circuit Court of Cook County, Illinois, or the United States 
District Court for the Northern District of Illinois, in any action, suit, or 
proceeding which the Agent or a Lender may at any time wish to file in 
connection with this Guaranty or any related matter.  The Guarantor hereby 
agrees that an action, suit, or proceeding to enforce this Guaranty may be 
brought in any state or federal court in the State of Illinois and hereby 
waives any objection which the Guarantor may have to the laying of the venue 
of any such action, suit, or proceeding in any such court; provided, however, 
that the provisions of this 


                                      -5-
<PAGE>

Paragraph shall not be deemed to preclude the Agent or a Lender from filing 
any such action, suit, or proceeding in any other appropriate forum.

13.  All notices and other communications provided to any party hereto under 
this Agreement or any other Credit Document shall be in writing or by telex 
or by facsimile and addressed or delivered to such party at its address set 
forth below or at such other address as may be designated by such party in a 
notice to the other parties.  Any notice, if mailed and properly addressed 
with postage prepaid, shall be deemed given when received; any notice, if 
transmitted by telex or facsimile, shall be deemed given when transmitted 
(answerback confirmed in the case of telexes).  Notice may be given as 
follows:

    The Series 1997 Bonds shall be designated "City of Chicago Variable/Fixed 
Rate Demand Special Facilities Airport Revenue Bonds (CenterPoint O'Hare, 
L.L.C. Project) Series 1997."  The total aggregate principal amount of Series

which is hereby incorporated by reference and made a part hereof, and in the 
denominations provided for in the Series 1997 Bonds.  The Series 1997 Bonds 
may have notations, legends or endorsements required by law or usage.

    Each Series 1997 Bond shall be dated the date of the original issuance and
delivery of the Bonds and shall mature, subject to prior redemption, on the
Maturity Date.  Series 1997 Bonds issued in exchange for Series 1997 Bonds
surrendered for transfer or exchange or in replacement of mutilated, lost,
stolen, destroyed or Undelivered Bonds shall bear interest from the last date to
which interest has been paid on the Series 1997 Bonds being transferred,
exchanged or replaced or, if no interest has been paid, from the

                                   -10-

<PAGE>

date of the original issuance and delivery of the Series 1997 Bonds.  Series 
1997 Bonds shall be numbered as determined by the Trustee.

    Upon the execution and delivery of this Indenture, the City shall execute
and deliver to the Trustee and, upon receipt by the Trustee of a Letter of
Credit satisfying the requirements of Article V, the Trustee shall authenticate,
the Series 1997 Bonds and deliver them to the purchaser or purchasers as
directed by the City.

    SECTION 2.02.  INTEREST ON THE SERIES 1997 BONDS.  Interest on the Series
1997 Bonds shall be payable as provided in the Series 1997 Bonds and in this
Section 2.02.  Interest on the Series 1997 Bonds shall initially be payable at
the Weekly Rate.  The interest rate determination method may be changed by the
Company as described in the following subsection (b).  The effective date of any
such change in the interest rate determination method shall be the first day of
the first Interest Period during which the Bonds shall bear interest at a rate
determined by the new method.  The methods of determining the interest rate on
the Bonds are as provided in the following subsection (a).

    (a)  INTEREST RATE DETERMINATION METHODS.  While there exists an Event of
Default, the interest rate on each Series 1997 Bond shall be the interest rate
on such Series 1997 Bond on the day before the Event of Default occurred.

         (1)  DAILY RATE.  When interest on the Series 1997 Bonds is payable at
    a Daily Rate, the Remarketing Agent shall set the Daily Rate on or before
    9:30 a.m., New York City time, on each Business Day for that Business Day. 
    Each Daily Rate shall be the minimum rate necessary (as determined by the
    Remarketing Agent based on the examination of tax-exempt obligations
    comparable to the Series 1997 Bonds known by the Remarketing Agent to have
    been priced or traded under then-prevailing market conditions) for the
    Remarketing Agent to sell the Series 1997 Bonds on the effective date of
    such Daily Rate at their principal amount (without regard to accrued
    interest). The Daily Rate for any non-Business Day shall be the Daily Rate
    for the last day on which a Daily Rate was set.

                                   -11-

<PAGE>

         (2)  WEEKLY RATE.  The Remarketing Agent shall set a Weekly Rate on or
    before 4:30 p.m., New York City time, on the last Business Day before the
    commencement of a period during which the Series 1997 Bonds will bear
    interest at a Weekly Rate and on each Tuesday thereafter so long as
    interest on the Series 1997 Bonds is to be payable at a Weekly Rate or, if
    any Tuesday is not a Business Day, on the next preceding Business Day. 
    Each Weekly Rate shall be the minimum rate necessary (as determined by the
    Remarketing Agent based on the examination of tax-exempt obligations
    comparable to the Series 1997 Bonds known by the Remarketing Agent to have
    been priced or traded under then-prevailing market conditions) for the
    Remarketing Agent to sell the Series 1997 Bonds on the effective date of
    such Weekly Rate at their principal amount (without regard to accrued
    interest).  The first Weekly Rate shall apply to the period beginning on
    the date of original issuance and delivery of the Series 1997 Bonds and
    ending on the next Tuesday.  Thereafter, each Weekly Rate shall apply to
    (i) the period beginning on the Wednesday of the week in which such Weekly
    Rate is set and ending on the following Tuesday or, if earlier, ending on
    the day before the effective date of a new method of determining the
    interest rate on the Series 1997 Bonds or (ii) the period beginning on the
    effective date of a change to a Weekly Rate and ending on the next Tuesday.

         (3)  COMMERCIAL PAPER RATE.  During a Commercial Paper Mode, each
    Series 1997 Bond shall bear interest during the Commercial Paper Period
    then applicable to such Series 1997 Bond at the then applicable Commercial
    Paper Rate for such Series 1997 Bond.  Different Commercial Paper Periods
    may apply to different Series 1997 Bonds at any time and from time to time. 
    Except as otherwise described in this subdivision (3), the Commercial Paper
    Period and Commercial Paper Rate for each Series 1997 Bond shall be
    determined by the Remarketing Agent no later than 4:30 p.m., New York City
    time, on the first day of each Commercial Paper Period.

         (i)  DETERMINATION OF COMMERCIAL PAPER PERIODS.  Each Commercial Paper
    Period shall be a period of at least one day and not more than 365 days,
    determined by the

                                   -12-

<PAGE>

    Remarketing Agent to be the period which, together with all other 
    Commercial Paper Periods for all Series 1997 Bonds then Outstanding, will 
    result in the lowest overall interest expense on the Series 1997 Bonds 
    over the next 365 days.  Each Commercial Paper Period shall end on either 
    the day before a Business Day or on the day before the Maturity Date.  
    However, any Series 1997 Bond purchased on behalf of the Company and 
    remaining unsold by the Remarketing Agent as of the close of business on 
    the first day of a Commercial Paper Period for such Series 1997 Bond 
    shall have a Commercial Paper Period of one day or, if that Commercial 
    Paper Period would not end on a day before a Business Day, a Commercial 
    Paper Period of the shortest possible duration greater than one day and 
    ending on a day before a Business Day.

         In determining the number of days in each Commercial Paper Period, 
    the Remarketing Agent shall take into account the following factors: (I) 
    existing short-term tax-exempt market rates and indices of such 
    short-term rates, (II) the existing market supply and demand for 
    short-term tax-exempt securities, (III) existing yield curves for 
    short-term and long-term tax-exempt securities for obligations of credit 
    quality comparable to the Series 1997 Bonds, (IV) general economic 
    conditions, (V) industry economic and financial conditions that may 
    affect or be relevant to the Series 1997 Bonds, (VI) the number of days 
    in other Commercial Paper Periods applicable to the Series 1997 Bonds and 
    (VII) such other facts, circumstances and conditions as the Remarketing 
    Agent, in its sole discretion, shall determine to be relevant.

         (ii) DETERMINATION OF COMMERCIAL PAPER RATES.  The Commercial Paper
    Rate for each Commercial Paper Period for each Series 1997 Bond shall be
    the minimum rate necessary (as determined by the Remarketing Agent based on
    the examination of tax-exempt obligations comparable to the Series 1997
    Bonds known by the Remarketing Agent to have been priced or traded under
    the then-prevailing market conditions) for the Remarketing Agent to sell
    such Series 1997

                                   -13-

<PAGE>

    Bond on the effective date of such Commercial Paper Rate at its principal 
    amount (without regard to accrued interest).

         Notwithstanding anything in this Indenture to the contrary, no
    Commercial Paper Period may be established (i) in respect of Series 1997
    Bonds to be redeemed or purchased in lieu of redemption after the making of
    a determination requiring a "MANDATORY REDEMPTION ON DETERMINATION OF
    TAXABILITY" as described in Section 8 of the Series 1997 Bonds and (ii)
    unless the Letter of Credit, if any, terminates no earlier than 20 days
    after the last day of such Commercial Paper Rate Period.

         (4)  LONG-TERM INTEREST RATE.  The Remarketing Agent shall set a 
    Long-Term Interest Rate on a date no later than the day before the 
    beginning of any period (a "LONG-TERM INTEREST RATE PERIOD") during which 
    interest on the Series 1997 Bonds will be payable at a Long-Term Interest 
    Rate.  Each Long-Term Interest Rate shall be the minimum rate necessary 
    (as determined by the Remarketing Agent based on the examination of 
    tax-exempt obligations comparable to the Series 1997 Bonds known by the 
    Remarketing Agent to have been priced or traded under then-prevailing 
    market conditions) for the Remarketing Agent to sell the Series 1997 
    Bonds on the effective date of such Long-Term Interest Rate at their 
    principal amount (without regard to accrued interest).  The Long-Term 
    Interest Rate Period shall be determined as provided in the following 
    subsection (b).

         (5)  FAILURE OF REMARKETING AGENT TO ANNOUNCE INTEREST RATES ON THE
    SERIES 1997 BONDS.  In the event that the appropriate interest rate or
    Commercial Paper Period is not or cannot be determined for whatever reason,
    the method of determining interest on the Series 1997 Bonds shall be
    converted automatically to the Weekly Rate (without the necessity of
    complying with the requirements of Section 2.02(b)) and the interest rate
    shall be equal to the PSA Municipal Index, provided that if such index is
    no longer provided by Municipal Market Data, Inc. or its successor, the
    rate shall be equal to the J.J. Kenny Index or if such index is not
    available,

                                   -14-

<PAGE>

    such other index (or percentage of an index) deemed appropriate for
    tax-exempt securities of the nature of the Series 1997 Bonds as the
    Remarketing Agent, with the consent of the Trustee, may have previously
    selected; PROVIDED that if the Series 1997 Bonds are then in a Long-Term
    Interest Rate Period, the Series 1997 Bonds shall bear interest at a Weekly
    Rate, but only if a Favorable Opinion of Tax Counsel with respect to the
    change to a Weekly Rate has been delivered to the Trustee and not rescinded
    prior to the effective date of such conversion.  If such Favorable Opinion
    of Tax Counsel has not been delivered or has been delivered but thereafter
    rescinded prior to the effective date of such conversion, the Series 1997
    Bonds shall remain in a Long-Term Interest Rate Period with an interest
    rate equal to the interest rate for the immediately prior Long-Term
    Interest Rate Period and with a duration equal to such Long-Term Interest
    Rate Period (or, if shorter, a Long-Term Interest Rate Period ending on the
    day before the Maturity Date).  The Trustee shall promptly notify the
    holders of Series 1997 Bonds of any such automatic change as set forth in
    Section 2.02(c).  While Series 1997 Bonds are in a Commercial Paper Mode,
    during any transition period caused by an automatic conversion of such
    Series 1997 Bonds to a Weekly Rate in accordance with this subdivision (5),
    Series 1997 Bonds bearing interest at a Weekly Rate and Series 1997 Bonds
    bearing interest at a Commercial Paper Rate, as applicable, shall be
    governed by the provisions of this Indenture applicable to such methods of
    determining interest on the Series 1997 Bonds, respectively.

    (b)  (1)  CHANGE IN INTEREST RATE DETERMINATION METHOD.  The Company may
change the method of determining the interest rate on the Series 1997 Bonds by
notifying the City, the Trustee, the Bank, the Remarketing Agent and, if the
Book-Entry System is then in effect for the Series 1997 Bonds, the Securities
Depository.  Such notice shall contain (a) the effective date of the change (as
specified in the fourth sentence of this Section 2.02), (b) the new interest
rate determination method and (c) if the change is to a Long-Term Interest Rate,
the last day of the first Long-Term Interest Rate Period and, at the option of
the Company, the effective date and last day of any succeeding Long-Term
Interest Rate Period or Periods (which last day for each Long-Term Interest Rate
Period must be either the day before the Maturity Date or a day before a
Business Day

                                   -15-

<PAGE>

which is at least 365 days after the effective date).  The notice must be 
accompanied by a Favorable Opinion of Tax Counsel, except as described below. 
Except in the case of the rescission of such Favorable Opinion of Tax Counsel 
as described in Section 2.02(e), if the Company's notice complies with this 
subsection (b), the interest rate on the Series 1997 Bonds shall be 
determined in accordance with the method specified therein, to become 
effective on the date specified therein; and such new method shall continue 
in effect until there is another change as provided in this Section 2.02.  
Notwithstanding anything in this Indenture to the contrary, the Company must 
deliver a Favorable Opinion of Tax Counsel whenever there is a change from a 
method during which the interest rate on the Series 1997 Bonds is set at 
intervals of one year or less to a method during which the interest rate on 
the Series 1997 Bonds is set at intervals in excess of one year, or vice 
versa.

    If at any time the Series 1997 Bonds shall bear interest at a Long-Term
Interest Rate and 30 days before the end of the then current Long-Term Interest
Rate Period the Company shall not have provided for the next interest rate
period, a new Long-Term Interest Rate Period of the same duration shall follow
(or, if shorter, a Long-Term Interest Rate Period ending on the day before the
Maturity Date).

    When one Long-Term Interest Rate Period succeeds another, all provisions of
this Indenture applying to a change in the interest rate determination method
shall apply, except:

         (A)  there shall be no redemption as described under "MANDATORY
    REDEMPTION UPON A CHANGE IN THE METHOD OF DETERMINING THE INTEREST RATE ON
    THE SERIES 1997 BONDS" in Section 8 of the Series 1997 Bonds; 

         (B)  the Company shall not be required to deliver a Favorable Opinion
    of Tax Counsel if the new Long-Term Interest Rate Period automatically
    occurs because the Company has not provided for the next Long-Term Interest
    Rate Period as described in the preceding paragraph; and

                                   -16-

<PAGE>

         (C)  the Company shall not be required to deliver a Favorable Opinion
    of Tax Counsel if the Company has previously designated one or more
    successive Long-Term Interest Rate Periods substantially equal in length to
    the then current Long-Term Interest Rate Period and if a Favorable Opinion
    of Tax Counsel was delivered before the first such Long-Term Interest Rate
    Period.

    (2)  LIMITATIONS.  Any change in the method of determining the interest
rate on the Series 1997 Bonds pursuant to subdivision (1) above must also comply
with the following:

         (i)  the effective date of the change (or each effective date in the
    case of a change from a Commercial Paper Mode) shall be a Business Day
    which is at least 15 days (30 days if the effective date is earlier than
    the day after the last day of the then current Long-Term Interest Rate
    Period) after the fifth Business Day (or such shorter period as shall be
    agreed to by the Trustee) following receipt by the Trustee of the Company's
    notice of change;

         (ii) if a Long-Term Interest Rate is then in effect, the effective
    date of any change must be either (A) the day after the last day of the
    then current Long-Term Interest Rate Period or (B) provided that the
    Company delivers a Favorable Opinion of Tax Counsel on the date notice of
    such change is given to the Trustee, any other day on which the Series 1997
    Bonds would be subject to redemption as described under the paragraph
    captioned "OPTIONAL REDEMPTION DURING LONG-TERM INTEREST RATE PERIOD" in
    Section 8 of the Series 1997 Bonds;

         (iii)     if the Company designates successive Long-Term Interest Rate
    Periods, the effective date of each later Long-Term Interest Rate Period
    must be the day after the last day of the immediately preceding Long-Term
    Interest Rate Period;

                                   -17-

<PAGE>

         (iv) if a Commercial Paper Mode is then in effect, the effective date
    of any change must be either the day after the last day of the then current
    Commercial Paper Mode or, as to any Series 1997 Bond, the day after the
    last day of the Commercial Paper Period then in effect (or to be in effect)
    with respect to such Series 1997 Bond;

         (v)  (A) if any Series 1997 Bonds have been called for redemption and
    the redemption has not yet been effected, the effective date of the change
    cannot occur before the redemption date, and (B) after a determination is
    made requiring a redemption as described under "MANDATORY REDEMPTION ON
    DETERMINATION OF TAXABILITY" in Section 8 of the Series 1997 Bonds, no
    change in the method of determining the interest rate on the Series 1997
    Bonds may become effective until such redemption or purchase in lieu of
    redemption has been effected;

         (vi) if a Commercial Paper Mode is then in effect, the Remarketing
    Agent shall determine Commercial Paper Periods of such duration as will, in
    the judgment of the Remarketing Agent, best promote an orderly transition
    to the new method; and after the receipt by the Trustee of the Company's
    notice of such change, the day after the last day of the then current
    Commercial Paper Period for each Series 1997 Bond shall be, with respect to
    such Series 1997 Bond, the effective date of such change; and the
    Remarketing Agent shall promptly give written notice of each such last day
    and each such effective date with respect to each Series 1997 Bond to the
    City, the Company and the Trustee; 

         (vii)     if a Long-Term Interest Rate or a Daily Rate is then in
    effect, the effective date of any change cannot occur during the period
    after a Record Date and to, but not including, the related Interest Payment
    Date; and

         (viii)    if a Letter of Credit is then in effect, the number of days
    of interest covered by the Letter of Credit shall be as set forth in
    Article V.

                                   -18-

         During any transition period, Series 1997 Bonds bearing interest at a
    Commercial Paper Rate shall be governed by the provisions of this Indenture

    interest at a Daily Rate, Weekly Rate or Long-Term Interest Rate, as
    applicable, shall be governed by the provisions of this Indenture

    1997 Bonds.

DETERMINATION METHOD.  When a change in the method of determining the interest
rate on the Series 1997 Bonds is to be made, or upon the commencement of any new
Long-Term Interest Rate Period, the Trustee will notify the holders of Series
1997 Bonds by first-class mail at least 15 days before the effective date (or
each effective date in the case of a change from a Commercial Paper Mode) of
such change or new period, except that such notice shall be given at least 30
days prior to the effective date if a Long-Term Interest Rate is then in effect
and the effective date is earlier than the day after the last day of the then
current Long-Term Interest Rate Period.  The notice shall state:

         (1)  that the interest rate determination method for the Series 1997
    Bonds will be changed and what the new method will be;

         (2)  the effective date of the change; and

         (3)  that the Series 1997 Bonds will be subject to mandatory
    redemption on the effective date of the change, as provided in Section 8 of
    the Series 1997 Bonds.

    The information required in any notice pursuant to this subsection (c) and
the information required in any redemption notice (including an Additional
Notice) pursuant to Section 3.04 may be combined in a single notice if the same
shall be sent to holders of Series 1997 Bonds in the manner and at the time
specified in "NOTICE OF REDEMPTION" in Section 8 of the Series 1997 Bonds.

                                   -19-

    (d)  CALCULATION OF INTEREST.  The Remarketing Agent shall provide the
Trustee, the Bank and the Company with notice in writing or by telephone
(promptly confirmed by facsimile transmission):

         (1)  by 3:00 p.m., New York City time, on the last Business Day of
    each month during which interest on the Series 1997 Bonds is payable at a
    Daily Rate, the Daily Rate for each day in such month;

         (2)  by 9:00 a.m., New York City time, on the Business Day after each
    day on which a Weekly Rate is set, such Weekly Rate;

         (3)  by 9:00 a.m., New York City time, on the Business Day after the
    first Business Day of each Commercial Paper Period, the duration thereof
    and the related Commercial Paper Rate, PROVIDED that, for Commercial Paper
    Periods of only one Business Day such information shall be provided by
    12:00 noon on the first day of such Commercial Paper Period; 

         (4)  on the first Business Day of each Long-Term Interest Rate Period,
    the duration thereof and the related Long-Term Interest Rate; and

         (5)  on a Business Day preceding any redemption date, any interest
    rate required by the Trustee in order to enable it to calculate the accrued
    interest, if any, due on such redemption date.

    Using the interest rates supplied by such notices, the Trustee shall
calculate the amount of interest payable on the Series 1997 Bonds.  The
Remarketing Agent shall inform the Trustee, the Bank and the Company orally
(promptly confirmed by facsimile, if requested) at the oral request of either of
them of any interest rate set by the Remarketing Agent.  The Remarketing Agent
shall confirm the current interest rate by telephone or in writing to any holder
of Series 1997 Bonds who requests it in any manner.

    The setting of interest rates and the calculation of the amount of interest
payable on the Series 1997 Bonds, as provided in this Indenture, shall be
conclusive and binding on the parties to the Indenture, the

                                   -20-

<PAGE>

Company, the Bank, the Remarketing Agent and the holders of Series 1997 Bonds.

    (e)  CHANGE IN RATE DETERMINATION METHOD-OPINIONS OF COUNSEL. 
Notwithstanding any other provision of this Section 2.02, no change shall be
made in the method of determining the interest rate on the Series 1997 Bonds at
the direction of the Company pursuant to Section 2.02(b)(1) if the Trustee shall
receive written notice prior to the effective date of such change that the
Favorable Opinion of Tax Counsel required by Section 2.02(b)(1) or Section
2.02(b)(2)(ii) has been rescinded.  If the Trustee shall have sent notice to the
holders of Series 1997 Bonds regarding such change under Section 2.02(c), the
Trustee shall promptly notify the holders of Series 1997 Bonds of such
rescission and the Series 1997 Bonds shall continue to bear interest in
accordance with the current method.

    SECTION 2.03.  EXECUTION AND AUTHENTICATION.  The Bonds shall be signed on
behalf of the City by the manual or facsimile signature of its Mayor or Chief
Financial Officer and attested by the manual or facsimile signature of its City
Clerk, and the seal of the City shall be impressed or imprinted on the Bonds by
facsimile or otherwise.  All authorized facsimile signatures shall have the same
effect as if manually signed.  If an officer of the City whose signature is on a
Bond no longer holds that office at the time the Trustee authenticates the Bond,
the Bond shall nevertheless be valid.  Also, if a person signing a Bond is the
proper officer on the actual date of execution, the Bond shall be valid even if
that person is not the proper officer on the nominal date of action.

    A Bond shall not be valid or become obligatory for any purpose or be
entitled to any security or benefit under this Indenture until the Trustee
manually signs the certificate of authentication on such Bond.  Such signature
shall be conclusive evidence that such Bond has been authenticated under this
Indenture.

    SECTION 2.04.  BOND REGISTER.  Bonds must be presented at the principal
corporate trust office of the Trustee for registration of transfer, exchange and
payment.  Bonds tendered by their Owners must be delivered as specified in the
Bonds.  The Trustee shall keep a register of Bonds and of

                                   -21-

<PAGE>

their transfer and exchange, which register shall be open to inspection by 
the City and the Company during normal business hours.

    Bonds may be transferred only on the register maintained by the Trustee. 
Upon surrender for transfer of any Bond to the Trustee, duly endorsed for
transfer or accompanied by an assignment duly executed by the Owner or the
Owner's attorney duly authorized in writing, the City shall execute and the
Trustee shall authenticate and deliver a new Bond or Bonds in an equal aggregate
principal amount and registered in the name of the transferee.

    Bonds may be exchanged for an equal aggregate principal amount of Bonds of
different authorized denominations.  The City shall execute and the Trustee
shall authenticate and deliver the new Bond or Bonds that the Bondholder making
the exchange is entitled to receive, bearing numbers not then outstanding.

    Except in connection with the purchase of Bonds tendered for purchase or
purchased in lieu of redemption, the Trustee shall not be required to transfer
or exchange any Bond called for redemption or during the period beginning 15
days before the mailing of a notice calling the Bonds or any portion of the
Bonds for redemption and ending on the redemption date.  In the event the
Trustee transfers such Bonds, the new owner shall be given notice of the pending
redemption.

    The Owner of a Bond shall be the absolute owner of such Bond for all
purposes, and all payments of principal, premium, if any, interest or purchase
price shall be made only to or upon the written order of such Owner or such
Owner's legal representative.

    The Trustee shall require the payment by a Bondholder requesting exchange
or transfer of any tax or other governmental charge required to be paid in
respect of the exchange or transfer but will not impose any other charge.

    If any Bond is mutilated, lost, stolen or destroyed, the City shall
execute and the Trustee shall authenticate and deliver a new Bond of the same
denomination if any mutilated Bond shall first be surrendered to the Trustee,
and if, in the case of any lost, stolen or destroyed Bond, there shall

                                   -23-

<PAGE>

first be furnished to the City, the Trustee, the Bank and the Company 
evidence of such loss, theft or destruction, together with an indemnity 
satisfactory to them.  If such Bond has matured, instead of issuing a 
replacement Bond, the Trustee may with the consent of the Company pay such 
Bond without requiring surrender of such Bond upon satisfaction of such 
requirements as the Trustee deems fit for the protection of the City, the 
Company and the Trustee, including a lost instrument bond.  The City, the 
Company and the Trustee may charge reasonable fees and expenses in this 
connection.

    If a Series 1997 Bond is called for redemption and the Company elects to
purchase such Bond in lieu of redemption as provided in Article III, or if the
Owner of a Series 1997 Bond gives irrevocable notice of tender to the
Remarketing Agent, and in either case if funds are deposited with the Trustee
sufficient for the purchase or purchase in lieu of redemption, upon request of
the Company or the Remarketing Agent, the City shall execute and the Trustee
shall authenticate a new Series 1997 Bond in the same denomination registered as
the Company or the Remarketing Agent may direct and deliver it to the Company or
its order, whether the Series 1997 Bond so purchased is ever delivered, but if
the funds are obtained by a drawing on the Letter of Credit, the Trustee must
comply with Section 3.08(a)(3).  From and after the purchase date, interest on
the purchased Series 1997 Bond shall cease to be payable to the prior Owner
thereof; such Owner shall cease to be entitled to the benefits or security of
this Indenture and shall have recourse solely to the funds held by the Trustee
for the purchase of such Series 1997 Bond, and the Trustee shall not register
any further transfer of such Series 1997 Bond by such prior Owner.

    SECTION 2.07.  CANCELLATION OF BONDS.  Whenever a Bond is delivered to the
Trustee for cancellation (upon payment, redemption or otherwise), or for
transfer, exchange or replacement pursuant to Section 2.05 or 2.06, the Trustee
shall promptly cancel and destroy such Bond and deliver a certificate of
destruction to the Company and the City.

    SECTION 2.08.  TEMPORARY BONDS.  Until definitive Bonds are ready for
delivery, the City may execute and the Trustee shall authenticate and deliver
temporary Bonds substantially in the form of the definitive

                                   -23-

<PAGE>

Bonds, with appropriate variations.  The City shall, without unreasonable 
delay, prepare and execute and the Trustee shall authenticate and deliver 
definitive Bonds in exchange for the temporary Bonds.  Such exchange shall be 
made by the Trustee without charge.

    SECTION 2.09.  BOOK-ENTRY SYSTEM.  The Series 1997 Bonds shall be 
initially registered in the name of Cede & Co., as nominee for The Depository 
Trust Company as the initial Securities Depository, and held in the custody 
of the Securities Depository.  A single certificate shall be issued and 
delivered to the Securities Depository for the Series 1997 Bonds.  The actual 
purchasers of the Series 1997 Bonds (the "BENEFICIAL OWNERS") will not 
receive physical delivery of Series 1997 Bond certificates except as provided 
herein.  So long as there exists a Securities Depository as provided herein, 
all transfers of beneficial ownership interests in the Series 1997 Bonds 
shall be made by book-entry only, and no person purchasing, selling or 
otherwise transferring beneficial ownership interests in the Series 1997 
Bonds will be permitted to receive, hold or deliver any Series 1997 Bond 
certificate.  The City, the Company and the Trustee shall treat the 
Securities Depository or its nominee as the sole and exclusive Owner of 
Series 1997 Bonds for all purposes, including payments of principal of, 
premium, if any, and interest on the Bonds, notices and voting.

    The City and the Trustee covenant and agree, so long as The Depository
Trust Company shall continue to serve as Securities Depository for the Series
1997 Bonds, to meet the requirements of The Depository Trust Company with
respect to required notices and other provisions of the Letter of
Representations executed by the City, the Trustee and the Remarketing Agent with
respect to the Series 1997 Bonds.

    The City, the Trustee and the Remarketing Agent may conclusively rely upon
(i) a certificate of the Securities Depository as to the identity of the
Participants in the Book-Entry System with respect to the Series 1997 Bonds and
(ii) a certificate of any such Participant as to the identity of, and the
respective principal amount of Bonds beneficially owned by, the Beneficial
Owners.

    Whenever Series 1997 Bonds remain Outstanding and the beneficial ownership
thereof must be determined by the books of the Securities

                                   -24-

<PAGE>

Depository, the requirements in this Indenture for holding, delivering, 
tendering or transferring Series 1997 Bonds shall be deemed modified to 
require the appropriate person to meet the requirements of the Securities 
Depository with respect to such actions to produce the same effect.  Any 
provision hereof permitting or requiring delivery of Series 1997 Bonds shall, 
while the Series 1997 Bonds are in the Book-Entry System, be satisfied by 
notation on the books of the Securities Depository in accordance with state 
law.

    The Trustee and the City, at the direction and expense of the Company and
with the consent of the Remarketing Agent, may from time to time appoint a
successor Securities Depository and enter into any agreement with such
Securities Depository to establish procedures with respect to the Series 1997
Bonds not inconsistent with the provisions of this Indenture.  Any successor
Securities Depository shall be a "clearing agency" registered under Section 17A
of the Securities Exchange Act of 1934, as amended.

    None of the City, the Company, the Trustee and the Remarketing Agent shall
have any responsibility or obligation to any Securities Depository, any
Participant in the Book-Entry System or the Beneficial Owners with respect to
(i) the accuracy of any records maintained by the Securities Depository or any
Participant; (ii) the payment by the Securities Depository or by any Participant
of any amount due to any Beneficial Owner in respect of the principal amount
(including premium) or redemption or purchase price of, or interest on, any
Series 1997 Bonds; (iii) the delivery of any notice by the Securities Depository
or any Participant; (iv) the selection of the Beneficial Owners to receive
payment in the event of any partial redemption of the Series 1997 Bonds; or (v)
any other action taken by the Securities Depository or any Participant in
connection with the Series 1997 Bonds.

    Series 1997 Bond certificates shall be delivered to and registered in the
name of the Beneficial Owners only under the following circumstances:

         (a)  The Securities Depository determines to discontinue providing its
    service with respect to the Series 1997 Bonds and no successor Securities
    Depository is appointed as described above.  Such a determination may be
    made at any time by giving reasonable

                                   -25-

<PAGE>

    notice to the City or the Trustee and discharging its responsibilities with
    respect thereto under applicable law.

         (b)  The Company determines not to continue the Book-Entry System
    through any Securities Depository.

If at any time the Securities Depository ceases to hold the Series 1997 Bonds,
all references herein to the Securities Depository shall be of no further force
or effect.

    A supplemental indenture authorizing Additional Bonds need not provide for
the same securities depository or any securities depository.

    SECTION 2.10.  ADDITIONAL BONDS.  Additional Bonds may be issued under and
secured by this Indenture at one time or from time to time, in addition to the
Series 1997 Bonds and, subject to the conditions hereinafter provided in this
Section 2.10, for the purposes set forth in Section 4.5 of the Loan Agreement. 
Such Additional Bonds shall be dated, shall be stated to mature on such date and
in such year or years, shall bear interest at such rate or rates, and may be
made redeemable at such times and prices, all as may be provided by the
supplemental indenture authorizing the issuance of such Additional Bonds. 
Additional Bonds may be issued as taxable or tax exempt.

    Such Additional Bonds shall be executed substantially in the form and
manner hereinabove set forth and shall be deposited with the Trustee for
authentication, but before such Additional Bonds shall be authenticated and
delivered by the Trustee, there shall be delivered to the Trustee the following:

         (a)  A written statement by the Company approving the terms,
    conditions, manner of issuance, delivery and contemplated disposition of
    the proceeds of the sale of such Additional Bonds and agreeing that the
    amounts payable under Section 4.2 of the Loan Agreement shall be computed
    so as to include such Additional Bonds.

                                   -26-

<PAGE>

         (b)  Original executed counterparts of the amendment to the Loan
    Agreement and the supplemental indenture.

         (c)  An Opinion of bond counsel to the effect that the Additional
    Bonds have been validly issued under the supplemental indenture and that
    all requirements under the supplemental indenture precedent to the delivery
    of the Additional Bonds have been satisfied.

         (d)  A request and authorization to the Trustee on behalf of the City
    and signed by an authorized officer to authenticate and deliver such
    Additional Bonds to or as directed by the purchaser or purchasers therein
    identified, registered in the names and in the denominations specified to
    the Trustee by the purchaser or purchasers, upon payment to the Trustee,
    but for the account of the City, of a sum specified in such request and
    authorization plus accrued interest, if any, on such Additional Bonds to
    the date of delivery.  The proceeds of the sale of such Additional Bonds
    shall be paid over to the Trustee and applied as provided in the
    supplemental indenture authorizing their issuance.



                                Article III

        REDEMPTION, PURCHASES IN LIEU OF REDEMPTION AND REMARKETING


    SECTION 3.01.  NOTICES TO TRUSTEE.  If the Company elects to redeem any
Bonds pursuant to any optional redemption provision in the Bonds, the Company
shall notify the Trustee of the applicable provision, the redemption date, the
principal amount of Bonds to be redeemed, the redemption price and other
necessary particulars.  The Company shall give such notice at least 45 days
before the redemption date.

    SECTION 3.02.  REDEMPTION DATES.  The redemption date of the Bonds to be
redeemed pursuant to any optional redemption provision in the Bonds shall be a
date permitted by the Bonds and specified by the Company in the notice delivered
pursuant to Section 3.01.  The redemption date for mandatory redemptions shall
be as specified in the Bonds or as determined by the Trustee consistently with
the provisions of the Bonds.

                                   -27-

<PAGE>

    SECTION 3.03.  SELECTION OF BONDS TO BE REDEEMED.  Except as otherwise
provided in the Bonds, and while a Book-Entry System is not in effect, if fewer
than all the Bonds of a series are to be redeemed, the Trustee shall select the
Bonds of that series to be redeemed by lot or other method it deems fair and
appropriate, except that the Trustee shall select, FIRST, any Bonds owned by the
Bank or any of its nominees or held by the Trustee for the account of the Bank
or any of its nominees and, SECOND, any Undelivered Bonds if the Company has
offered to purchase such Bonds in lieu of redemption.  The Trustee shall make
its selection from Bonds not previously called for redemption.  For this
purpose, the Trustee shall consider each Bond in a denomination larger than the
minimum denomination permitted by the Bonds at the time to be separate Bonds,
each in the minimum denomination.  Provisions of this Indenture that apply to
Bonds called for redemption shall also apply to portions of Bonds called for
redemption.  While a Book-Entry System is in effect, the procedures of the
Securities Depository shall control with respect to the selection of Bonds to be
redeemed.

    SECTION 3.04.  REDEMPTION NOTICES.  (a) OFFICIAL NOTICE OF REDEMPTION.  The
Trustee shall give notice of each redemption as provided in the Bonds and shall
at the same time give a copy of such notice to the Bank and the Remarketing
Agent, PROVIDED that no redemption notice shall be required with respect to a
redemption of Series 1997 Bonds under the paragraph captioned "MANDATORY
REDEMPTION ON EACH INTEREST PAYMENT DATE DURING COMMERCIAL PAPER MODE" in
Section 8 of the Bonds.  The notice shall identify the Bonds to be redeemed and
shall state (1) the redemption date, (2) the redemption price, (3) that the
Bonds called for redemption must be surrendered to collect the redemption price,
(4) the address at which the Bonds must be surrendered and (5) that interest on
the Bonds called for redemption ceases to accrue on the redemption date.  In
addition, if a Letter of Credit is expiring, the notice will state the
expiration date and that the expiration might result in reduction or withdrawal
of either of or both the Rating Agencies' ratings of the Bonds.

    With respect to any redemption of the Series 1997 Bonds under the paragraph
captioned "OPTIONAL REDEMPTION DURING LONG-TERM INTEREST RATE PERIOD,"
"EXTRAORDINARY OPTIONAL REDEMPTION" or "OPTIONAL REDEMPTION DURING DAILY OR
WEEKLY RATE PERIOD" in Section 8 of the Series

                                   -29-

<PAGE>

1997 Bonds, unless moneys sufficient to pay the principal of, and the 
premium, if any, and interest on, the Series 1997 Bonds to be redeemed shall 
have been received by the Trustee prior to the giving of such notice of 
redemption, such notice may state that said redemption shall be conditional 
upon the receipt of such moneys by the Trustee on or prior to the date fixed 
for redemption.  If such moneys are not received by the redemption date, such 
notice shall be of no force and effect, the City shall not redeem such Series 
1997 Bonds, the redemption price shall not be due and payable and the Trustee 
shall give notice, in the same manner in which the notice of redemption was 
given, that such moneys were not so received and that such Series 1997 Bonds 
will not be redeemed.

    The Trustee will give a notice of redemption under "MANDATORY REDEMPTION
UPON EXPIRATION OF LETTER OF CREDIT" or "MANDATORY REDEMPTION UPON DELIVERY OF
AN ALTERNATE LETTER OF CREDIT" in Section 8 of the Series 1997 Bonds under the
circumstances described in Section 5.01.

    Failure to give any required notice of redemption as to any particular
Bonds shall not affect the validity of the call for redemption of any Bonds in
respect of which no such failure has occurred.  Any notice mailed as provided in
the Bonds shall be conclusively presumed to have been given, whether or not
actually received by the addressee Owner.

    (b)  ADDITIONAL NOTICE OF REDEMPTION.  In addition to the redemption notice
required in subsection (a) above, if the Book-Entry System is not then in effect
for the Bonds, a further notice (the "ADDITIONAL NOTICE") shall be given by the
Trustee as set out below.  No defect in the Additional Notice nor any failure to
give all or any portion of the Additional Notice shall in any manner defeat the
effectiveness of a call for redemption if the notice required in subsection (a)
above is given.

         (1)  Each Additional Notice shall contain (i) the CUSIP numbers of all
    Bonds being redeemed; (ii) the date of original issuance of the Bonds;
    (iii) the interest rate determination method for, or the rate of interest
    borne by, each Bond being redeemed; (iv) the Maturity Date of the Bonds;
    and (v) any other descriptive information needed to identify accurately the
    Bonds being redeemed.

                                   -29-

<PAGE>

         (2)  Each check or other transfer of funds issued for payment of the
    redemption price of the Bonds being redeemed shall bear the CUSIP number
    identifying, by issue and maturity, the Bonds being redeemed with the
    proceeds of such check or other transfer.

         (3)  Each Additional Notice shall be sent at least 35 days before the
    redemption date by registered or certified mail or overnight delivery
    service to all registered securities depositories then in the business of
    holding substantial amounts of obligations similar to the Bonds (such
    depositories now being The Depository Trust Company of New York, New York
    and Philadelphia Depository Trust Company of Philadelphia, Pennsylvania)
    and to one or more national information services that disseminate notices
    of redemption of obligations such as the Bonds.

    The information required in any redemption notice (including an Additional
Notice) pursuant to this Section 3.04 and the information required in any notice
pursuant to Section 2.02(c) may be combined in a single notice if the same shall
be sent to Bondholders in the manner and at the time specified in "NOTICE OF
REDEMPTION" in Section 8 of the Bonds.

    SECTION 3.05.  PAYMENT OF BONDS CALLED FOR REDEMPTION.  Upon surrender to
the Trustee, Bonds called for redemption shall be paid or purchased in lieu of
redemption as provided in this Article III and the Bonds at the redemption price
stated in the notice, plus accrued interest, if any, to the redemption date, or
at a purchase price calculated as set forth in the Bonds, plus accrued interest,
if any, to the purchase date; PROVIDED, HOWEVER, that while a Book-Entry System
is in effect, the Bond held by the Securities Depository need not be surrendered
for a partial redemption.

    SECTION 3.06.  BONDS REDEEMED IN PART.  Upon surrender of a Bond to be
redeemed or purchased in lieu of redemption in part, the City shall execute and
the Trustee shall authenticate and deliver to the Owner a new Bond or Bonds of
the same series and maturity in authorized denominations equal in aggregate
principal amount to the unredeemed or unpurchased portion of the Bond
surrendered.

                                   -30-

<PAGE>

    SECTION 3.07.  PURCHASE OF SERIES 1997 BONDS IN LIEU OF REDEMPTION.  When
Series 1997 Bonds are called for redemption pursuant to the paragraphs captioned
"MANDATORY REDEMPTION AT BEGINNING OF A NEW LONG-TERM INTEREST RATE PERIOD,"
"MANDATORY REDEMPTION UPON A CHANGE IN THE METHOD OF DETERMINING THE INTEREST
RATE ON THE BONDS," "MANDATORY REDEMPTION UPON EXPIRATION OF LETTER OF CREDIT,"
"MANDATORY REDEMPTION UPON DELIVERY OF AN ALTERNATE LETTER OF CREDIT,"
"MANDATORY REDEMPTION ON DETERMINATION OF TAXABILITY," "MANDATORY REDEMPTION
DURING A LONG-TERM INTEREST RATE PERIOD UPON EXTENSION OF BOND MATURITY," 
"MANDATORY REDEMPTION AT THE DIRECTION OF THE BANK" or "MANDATORY REDEMPTION
UPON EXTENSION OF BOND MATURITY" in Section 8 of the Series 1997 Bonds, the
Company may purchase some of or all the Series 1997 Bonds (in authorized
denominations) called for redemption.  Unless the Company and the Bank give
written instructions to the Trustee no later than two Business Days prior to the
redemption date that the Company is not exercising its option to purchase the
Series 1997 Bonds in lieu of redemption, the Company shall be deemed to have
exercised such option and on the proposed redemption date the Trustee shall
purchase in lieu of redemption Series 1997 Bonds called for redemption pursuant
to any of the foregoing paragraphs.  The Trustee shall purchase Series 1997
Bonds pursuant to this Section  3.07 only as provided in Section 4.02.  Series
1997 Bonds purchased in lieu of redemption shall not be redeemed and shall
remain outstanding hereunder.  

    SECTION 3.08.  DISPOSITION OF PURCHASED SERIES 1997 BONDS.  (a) SERIES 1997
BONDS TO BE REMARKETED.  Series 1997 Bonds purchased pursuant to tenders as
provided in the Bonds or in lieu of redemption as provided in Section 3.07 shall
be offered for sale by the Remarketing Agent as provided in this Section 3.08,
except as follows:

         (1)  Series 1997 Bonds purchased pursuant to a tender after having
    been called for redemption under a provision in the Series 1997 Bonds that
    does not provide the Company an option to purchase in lieu of redemption
    shall be canceled.

         (2)  Series 1997 Bonds which are tendered between the date notice of
    any redemption is given and the redemption date may be remarketed before
    the redemption date only if the buyer receives a copy of the redemption
    notice from the Remarketing Agent.

                                   -31-

<PAGE>

         (3)  Series 1997 Bonds purchased with funds obtained by a drawing on 
    the Letter of Credit will be held by the Trustee as pledgeholder for the 
    benefit of the Bank (or, if the Series 1997 Bonds are held in the Book-Entry
    System, such Series 1997 Bonds shall be recorded in the books of the 
    Securities Depository for the account of the Trustee and shall be deemed 
    pledged to the Bank), all in accordance with the reimbursement agreement or 
    any pledge agreement under which the Letter of Credit is issued.  The Bank's
    security interest in such Series 1997 Bonds shall be released, and the 
    Trustee shall release such Series 1997 Bonds, only after the Trustee has 
    been notified in writing by the Bank that the Letter of Credit has been 
    reinstated by the amount of the funds drawn to purchase such Bonds (A) as
    a result of reimbursement by the Company to the Bank or (B) because such

      APPLICATION OF PROCEEDS AND PAYMENT OF SERIES 1997 BONDS

    SECTION 4.01.  APPLICATION OF PROCEEDS.  (a) The City will cause the
proceeds of the initial sale of the Series 1997 Bonds to be deposited with the
Trustee as described below.  The Trustee will hold those proceeds in trust for
the benefit of the Company and the Bondholders and will apply the proceeds in
accordance with this Section.

    The Trustee will deposit $1,092,820 of the proceeds of the initial sale 
of the Series 1997 Bonds into the "Costs of Issuance Fund" which is hereby 
created with the Trustee, to pay a portion of the costs of issuing the Series 
1997 Bonds, including, without limitation, the underwriting fee for the 
initial sale of the Series 1997 Bonds, all printing expenses in connection 
with the Indenture, the Loan Agreement, the Reimbursement Agreement, the 
preliminary offering memorandum and offering memorandum for the Series 1997 
Bonds; legal fees; Rating Agency fees; and the initial fees of the City and 
the Trustee.  The costs described above are payable upon submission of a 
written request from a Company Representative stating that the amount 
indicated thereon is justly due and owing, has not been the subject of 
another written request which has been paid and is a proper cost of issuing 
the Series 1997 Bonds.  Any moneys remaining in the Costs of Issuance Fund on 
the earlier of the payment of all costs of issuance of the Series 1997 Bonds 
or April 1, 1998 shall be transferred to the Project Fund and applied as 
described below.

                                   -34-

<PAGE>

    The Trustee will deposit all remaining proceeds from the initial sale of 
the Series 1997 Bonds and any excess proceeds from the Costs of Issuance Fund 
into the "Project Fund," which is hereby created with the Trustee.  Moneys in 
the Project Fund will be disbursed to pay the Project Costs and certain 
Non-Qualified Costs, or to reimburse the Company for Project Costs or certain 
Non-Qualified Costs paid by it, upon receipt of a requisition signed by a 
Company Representative stating with respect to each disbursement to be made, 
the following:

         (1)  that the costs of an aggregate amount set forth in such
    requisition have been made or incurred or financed and were necessary for
    the Project and were made or incurred in accordance with the construction
    contracts, plans and specifications and building permits therefor then in
    effect;

         (2)  that the amount paid or to be paid, as set forth in such
    requisition, represents either (i) capitalized interest and is to be used
    to pay interest on the Series 1997 Bonds or (ii) a part of the amount due
    and payable for Project Costs and that such payment was not paid in advance
    of the time, if any, fixed for payment and was made in accordance with the
    terms of any contracts applicable thereto and in accordance with usual and
    customary practice under existing conditions;

         (3)  that no part of the Project Costs was included within the costs
    referred to in any requisition previously filed with the Trustee under the
    provisions of this Indenture;

         (4)  that (i) the withdrawal of moneys from the Project Fund and the
    use of the property financed or reimbursed therefrom has not and will not
    result in a violation of any representation, term or covenant in the Tax
    Agreement and (ii) any Opinion of Tax Counsel required to be delivered as a
    result of changes to the Project pursuant to Section 3.2 of the Loan
    Agreement has been delivered to the Trustee and the City; 

         (5)  that the amount remaining in the Project Fund, together with (i)
    moneys then on hand at the Company or committed to the

                                   -35-

<PAGE>

    Company which are or will be available, and are anticipated by the 
    Company to be applied, to pay the Project Costs and (ii) expected 
    investment earnings to be deposited into the Project Fund pursuant to 
    this Indenture, will, after payment of the amount requested in said 
    requisition, be sufficient to pay the costs of completing the Project 
    substantially in accordance with the construction contracts, plans and 
    specifications and building permits therefor, if any, then in effect; and

         (6)  that the amounts paid or to be paid as set forth in the
    requisition are properly payable under the terms of this Indenture and that
    all conditions precedent to payment as prescribed in this Indenture have
    been satisfied.

    The Company may direct the use of not to exceed $2,165,000 of Series 1997
Bond proceeds (including all earnings thereon) to pay, in the aggregate, (i)
certain working capital costs directly related to the Project and to pay
interest on the Series 1997 Bonds which does not constitute Project Costs as
defined below because such interest costs would not be Capitalizable Costs as
defined below; (ii) costs of issuance, and (iii) any fees related to the Letter
of Credit (the "NON-QUALIFIED COSTS").  With respect to any requisition from the
Project Fund or the Costs of Issuance Fund that requests payment or
reimbursement of Non-Qualified Costs, the Company shall additionally certify
that, taking into account such requisition of Non-Qualified Costs, the running
total of Non-Qualified Costs paid or reimbursed from Series 1997 Bond proceeds
does not exceed the lesser of $2,165,000 or 4% of the sum of (i) amount of
Series 1997 Bond proceeds paid or reimbursed pursuant to all previous
requisitions and (ii) the amount of Series 1997 Bond proceeds requested to be
paid or reimbursed pursuant to the requisition to which such certification
relates.  

    The Company shall attach to each requisition a list of invoices or bills of
sale covering all items for which payment is being requested in such requisition
issued by the manufacturers, suppliers or other sellers of such items.  The
invoices or bills shall be available for review by the Trustee in the offices of
the Company; PROVIDED that the Trustee shall have no duty or obligation to
review such invoices and may conclusively rely on such requisitions.

                                   -36-

<PAGE>

    To the extent that the Company leases from third parties or otherwise
provides items for the Project from sources other than funds on deposit in the
Project Fund, the costs thereof shall not be included in the Project Costs
referred to above.

    The Trustee will maintain adequate records pertaining to the proceeds of
the Bonds held by it and all disbursement from them made by the Trustee.

    "PROJECT COSTS" means all costs that would be properly chargeable to the
acquisition, construction, installation or equipping of the Project or to its
financing if the City were a corporation subject to federal income taxation
("CAPITALIZABLE COSTS"), including, without limitation, the following:

         (A)  The cost of construction and acquisition of all lands,
    structures, real or personal property, rights, rights-of-way, franchises,
    easements and interests acquired or used for the Project and infrastructure

    related to the Project.

         (B)  The cost of demolishing or removing any buildings or structures
    on land so acquired, including the cost of acquiring any lands to which

    (b)  COMPLETION DATE.  The Company shall deliver to the City, the Trustee
and the Bank upon completion of the Project a certificate as described below
(the "COMPLETION CERTIFICATE") signed by a Company Representative stating the
following:

         1.   All portions of the Project have been fully completed in
    accordance with the plans and specifications therefor, as then amended, and
    the date of completion. 

         2.   Such persons have made such investigation of such sources of
    information as are deemed by such persons to be necessary, including
    pertinent records of the Company, and are of the opinion that the Project
    has been fully paid for and no claim or claims exist against the Company or
    against the properties of the Company or, to the best of such persons'
    knowledge, against the City or against the properties of the City, out of
    which a lien based on furnishing labor or material for the Project exists
    or might ripen; PROVIDED, HOWEVER, there may be excepted from the foregoing
    statement any claim or claims out of which a lien exists or might ripen in
    the event that the Company intends to contest such claim or claims, in
    which event such claim or claims shall be described; PROVIDED, FURTHER,
    HOWEVER, that in such event such certificate shall state that funds are on
    deposit in the Project Fund which, together with (i) moneys then on hand at
    the Company or committed to the Company which are or will be available, and
    are anticipated by the Company to be applied, to pay the Project Costs, and
    (ii) expected investment earnings to be deposited into the Project Fund
    pursuant to this Indenture, are sufficient to make payment of the full
    amount which might in any event be payable in order to satisfy such claim
    or claims.  In the event such certificate shall state that there is a claim
    or claims in controversy which create or might ripen into a lien, there
    shall be filed with the City and the Trustee a certificate of the Company
    Representative stating that such claim or claims have been paid when the
    same has in fact occurred.

         3.   The withdrawal of moneys from the Project Fund and the use of the
    property financed or reimbursed therefrom has not and will

                                   -38-

<PAGE>

    not result in a violation of any representation, term or covenant in the Tax
    Agreement. 

         4.   All Opinions of Tax Counsel required to be delivered as a result
    of changes made pursuant to Section 3.2 of the Loan Agreement have been

the following dates (the "REMEDIAL ACTION DATE") (i) the date on which the
Company determines that the Project will not be completed; or (ii) the date on
which the entire Project is placed in service (I.E., the date the Project is

    Date, all or part of the price of purchasing a portion of the Series 1997
    Bonds on tender, in the open market or at private sale, at a purchase price
    not in excess of 100 percent of the principal amount of such Series 1997
    Bonds plus accrued interest to the date of such purchase for the purpose of
    cancellation; 

              (b)  if the Series 1997 Bonds are callable within 90 days 
                   following the Remedial Action Date, to pay, on or before 
                   90 days following the Remedial Action Date, all or part

                                   -39-

<PAGE>

    of the redemption price of a portion of the Series 1997 Bonds; or

         (c)  if the Series 1997 Bonds are not callable within 90 days
    following the Remedial Action Date, for transfer into an escrow account
    established with the Trustee, upon filing required notice to the Internal
    Revenue Service, such transfer and notice to be on or before 90 days
    following the Remedial Action Date, to be used to pay, on the first date on
    which Series 1997 Bonds may be redeemed, but in any event within ten and
    one-half years from the date of issuance of the Series 1997 Bonds, all or
    part of the redemption price of a portion of the Series 1997 Bonds;

PROVIDED, that, except for the purpose described in subparagraph (1) above, no
money, including earnings on the investment on such moneys, may be so used
unless and until the Trustee has been furnished with a Favorable Opinion of Tax
Counsel; PROVIDED FURTHER that the earnings on the investment of the moneys on
deposit in such escrow account described in subparagraph (4)(c) above shall be
used to pay interest on the Series 1997 Bonds coming due on each interest
payment date on the Series 1997 Bonds (or to reimburse the Bank for draws under
the Letter of Credit to pay interest on the Series 1997 Bonds); and PROVIDED
FURTHER that, until used for the foregoing purpose described in subparagraph
(4)(c) above, moneys on deposit in such escrow account may be invested in
investments authorized by Section 4.03 hereof, but may not be invested to
produce a yield on such moneys (computed from the Placed in Service Date and
taking into account any investment of such moneys during the period from the
Placed in Service Date until such moneys were deposited in such escrow account)
greater than the yield on the Series 1997 Bonds from which such proceeds were
derived, all as such terms are used in and determined in accordance with the
Code and regulations promulgated thereunder.

    (d)  INVESTMENT OF PROJECT FUND MONEYS.  Moneys on deposit in the Project
Fund may be invested only in accordance with the provisions of Sections 5.4 and
5.5 of the Loan Agreement and Section 4.03 hereof, and income resulting
therefrom shall be credited to the Project Fund or the Rebate Fund as provided
in the Tax Agreement.

                                   -40-

<PAGE>

    (e)  EVENT OF DEFAULT.  If an Event of Default occurs and the maturity of
the Series 1997 Bonds is accelerated, the Trustee will to the extent necessary
use moneys in the Project Fund to reimburse the Bank for draws under the Letter
of Credit to make payments on the Series 1997 Bonds, regardless of the other
provisions of this Section.

    SECTION 4.02.  PAYMENTS OF SERIES 1997 BONDS.  When a Letter of Credit is
in effect, the Trustee will make payments of principal and purchase price
(whether pursuant to tenders or purchase in lieu redemption) of, and interest
on, the Series 1997 Bonds FIRST (for payment of purchase price of Series 1997
Bonds only), from the proceeds of the sale of Series 1997 Bonds under Section
3.08, except proceeds from Series 1997 Bonds sold by the Remarketing Agent to
the City or the Company or any "insider" of either of the foregoing (as defined
in the Bankruptcy Law); SECOND, from moneys drawn under the Letter of Credit;
THIRD, from any other moneys or securities if there is delivered to the Trustee
an Opinion of Counsel experienced in bankruptcy matters (which may assume that
no Owner is an "insider" as defined in the Bankruptcy Law) to the effect that
the use of such moneys or securities to pay the principal or purchase price of,
premium, if any, or interest on the Series 1997 Bonds would not be avoidable as
preferential payments under Section 547 of the Bankruptcy Law recoverable under
Section 550 of the Bankruptcy Law should the City or the Company become a debtor
in any proceeding commenced thereunder, which opinion shall also be addressed to
and acceptable to any Rating Agency then rating the Series 1997 Bonds; and LAST
from any other moneys available to the Trustee.  All moneys referred to in
clause FIRST of such sentence shall be held in a separate and segregated account
by the Trustee in the Purchase Fund, which is hereby created with the Trustee. 
However, payments of principal and interest on Series 1997 Bonds held by the
Company or by the Trustee for the account of the Company will be paid only from
the FIRST and LAST categories of moneys.  The proceeds of investments of any
moneys in any of these categories may be used to the same extent as if the
moneys invested could be used had they not been invested.  Funds in each
category will be held in a separate and segregated account and will not be
commingled with funds from the other categories or from any other source.  In
addition to the funds and accounts established in this Article IV, the Trustee
may establish such funds and accounts as it

                                   -41-

<PAGE>

deems necessary and appropriate in order to discharge its duties under this
Indenture.

    "BANKRUPTCY FILING" means the filing of a petition by or against the City
or the Company under any bankruptcy act or similar act.  If the petition has
been dismissed and the dismissal is final and not subject to appeal at the
relevant time, the filing will not be considered to have occurred.

    When a Letter of Credit is not in effect, the Trustee will make payments 
of principal of and interest on the Series 1997 Bonds and the purchase price 
of Series 1997 Bonds FIRST from the proceeds of the initial sale of the 
Series 1997 Bonds to the extent such proceeds are available for the purpose, 
SECOND (for payment of purchase price of Series 1997 Bonds only) from the 
proceeds of the sale of Series 1997 Bonds under Section 3.08, and THIRD from 
other moneys available to the Trustee for the purpose.  The proceeds of 
investments of any moneys in any of these categories may be used to the same 
extent as if the moneys invested could be used had they not be invested.  All 
moneys referred to in clauses FIRST and SECOND above shall each be held 
segregated by the Trustee.

    The Remarketing Agent will pay to the Trustee upon receipt the proceeds 
of sales of Series 1997 Bonds under Section 3.08.  The Trustee shall make 
payments of the principal of, and premium, if any, and interest on, the 
Series 1997 Bonds only from moneys available to the Trustee under this 
Indenture for that purpose. If the Remarketing Agent has been removed or has 
resigned and no successor Remarketing Agent has been appointed, the Trustee 
will pay the purchase price of tendered Series 1997 Bonds with any moneys 
available to it under this Indenture for such purpose.

    SECTION 4.03.  INVESTMENTS OF MONEYS.  Except as provided below, the 
Trustee shall invest and reinvest moneys held by the Trustee as directed by 
the Company Representative in any investment permitted by law and the Tax 
Agreement. In the absence of any other direction, the Company Representative 
has directed that such moneys be invested in a money market fund selected by 
the Trustee with a rating of "Am" or "Am-g" or better by a Rating Agency.

                                   -42-

<PAGE>

    Notwithstanding anything in this Indenture to the contrary, moneys held by
the Trustee which are proceeds of a drawing under the Letter of Credit shall not
be invested.

    The Trustee may make investments permitted by this Article IV through its
own bond department or the bond department of any bank or trust company under
common control with the Trustee.  Investments shall be made so as to mature or
be subject to redemption at the option of the holder on or before the date or
dates on which the Trustee anticipates that moneys from the investments will be
required.  Investments shall be registered in the name of the Trustee and held
by or under the control of the Trustee.  The Trustee shall sell and reduce to
cash a sufficient amount of investments whenever the cash held by the Trustee is
insufficient.  The Trustee shall not be liable for any loss from such
investments to the extent directed by the Company Representative and to the
extent such directions have been complied with by the Trustee.

    SECTION 4.04.  MONEYS HELD IN TRUST.  The Trustee shall hold in trust for
the benefit of the Bondholders all moneys held by it for any payment on the
Bonds.  Moneys in the Costs of Issuance Fund and the Project Fund shall be held
by the Trustee for the benefit of the owners and holders of the Bonds and
invested in accordance with Section 4.03 until disbursed as described in Section
4.01.  Money received by the Remarketing Agent or the Trustee from the sale of
any Series 1997 Bond under Section 3.08 or for the purchase of any Series 1997
Bond shall be held segregated from other funds of the Remarketing Agent or the
Trustee in trust for the benefit of the Series 1997 Bondholder from whom such
Series 1997 Bond was purchased or the person delivering such purchase money, as
the case may be, and shall not be invested.  The Trustee shall promptly, but in
no event later than 30 days after their original deposit, apply moneys received
from the Company in accordance with this Indenture and the Tax Agreement as
directed by the Company Representative.

1997 Bonds) at a stated maximum interest rate; and (B) if the Letter of 
Credit will be in effect during a Long-Term Interest Rate Period, the stated 
coverage amount of the Letter of Credit will include interest on the Series

AN ALTERNATE LETTER OF CREDIT," "MANDATORY REDEMPTION AT BEGINNING OF A NEW 
LONG-TERM INTEREST RATE PERIOD" and "MANDATORY REDEMPTION UPON A CHANGE IN 
THE METHOD OF DETERMINING THE INTEREST RATE ON THE BONDS"  and "MANDATORY 
REDEMPTION DURING A LONG-TERM INTEREST RATE PERIOD UPON EXTENSION OF BOND 
MATURITY" in Section 8 of the Series 1997 Bonds.  The Letter of Credit will 
expire (A) at its stated expiration date, which will be no earlier than 20 
days after an Interest Payment Date that (except for the initial Letter of 
Credit) is one year from its date of issuance, and if a Long-Term Interest 
Rate Period will be in effect, its stated expiration date will be no earlier 
than the first date on which the Series 1997 Bonds are subject to redemption 
as described under the paragraph "OPTIONAL REDEMPTION DURING LONG-TERM 
INTEREST RATE PERIOD" in Section 8 of the Series 1997 Bonds, (B) receipt by 
the Bank of Trustee certificates to the effect that all Bonds

                                     -44-

<PAGE>

have been paid or that an Alternate Letter of Credit has been delivered to 
and accepted by the Trustee; or (C) 25 days after the Trustee has received 
the Bank's written notice that an Event of Default has occurred under the 
Reimbursement Agreement pursuant to which the Letter of Credit was issued and 
requesting that the principal of all Bonds and accrued interest thereon be 
declared due and payable or be called for redemption.  

    At least 45 days (or such shorter period as shall be acceptable to the
Trustee, but not less than 30 days) prior to the Interest Payment Date next
preceding the Expiration Date of the current Letter of Credit, the Company may
provide for the delivery to the Trustee of an amendment to the Letter of Credit
which extends the Expiration Date to a date that is not earlier than one year
from its then current Expiration Date.  If the Letter of Credit is so extended,
the mandatory redemption described under the paragraph "MANDATORY REDEMPTION
UPON EXPIRATION OF LETTER OF CREDIT" in Section 8 of the Series 1997 Bonds shall
not occur.  Unless all of the conditions of this paragraph which are required to
be met 45 days (or such shorter period as shall be acceptable to the Trustee,
but not less than 30 days) preceding the Interest Payment Date next preceding
the Expiration Date of the Letter of Credit have been satisfied, the Trustee
shall take all action necessary to call the Series 1997 Bonds for mandatory
redemption described under the paragraph "MANDATORY REDEMPTION UPON EXPIRATION
OF LETTER OF CREDIT" in Section 8 of the Series 1997 Bonds on the Interest
Payment Date next preceding such Expiration Date; PROVIDED that if the Company
shall have notified the Trustee in writing that it expects to meet all the
conditions for the delivery of an amendment extending the existing Letter of
Credit on or before the Interest Payment Date next preceding the Expiration Date
of the existing Letter of Credit, then the notice of such mandatory redemption
shall state that it is subject to rescission, and the Trustee shall rescind such
notice, if such conditions are so met (in which case such mandatory redemption
shall not occur).

    (b)  ALTERNATE LETTER OF CREDIT.  The Company may elect to replace any
Letter of Credit with a new Letter of Credit conforming to the requirements of
Section 5.01(a).  

    In addition, if the method of determining interest on the Series 1997 Bonds
is a Daily, Weekly or Commercial Paper Rate, the Company may

                                     -45-

<PAGE>

elect to terminate the existing Letter of Credit (or elect not to replace an 
expiring Letter of Credit) by delivering to the Trustee at least 30 days 
before the end of the last full Interest Period before the termination or 
expiration of the Letter of Credit, a letter from each Rating Agency then 
rating the Series 1997 Bonds that the Series 1997 Bonds will be rated at 
least "A-1" or "P-1" (or its equivalent) after the termination or expiration 
of the Letter of Credit.  If such election is made, the Series 1997 Bonds 
will be called for redemption as described under the caption "MANDATORY 
REDEMPTION UPON EXPIRATION OF LETTER OF CREDIT" in Section 8 of the Series 
1997 Bonds.  

    Notwithstanding anything to the contrary contained herein, (1) unless the 
requirements of the preceding paragraph are met, while the Series 1997 Bonds 
bear interest at a Daily, Weekly or Commercial Paper Rate, they shall be 
secured by a Letter of Credit, and (2) if the Series 1997 Bonds bear interest 
at a Long-Term Interest Rate, they shall not be secured or supported by a 
Letter of Credit or any other type of credit enhancement unless, immediately 
prior to the effective date of any change in the method of determining the 
interest rate on the Series 1997 Bonds from a Daily, Weekly or Commercial 
Paper Rate, the Remarketing Agent makes an objective determination in a 
certificate delivered to the Trustee that the present value of the cost of 
securing the Series 1997 Bonds with the Letter of Credit or any other type of 
credit enhancement (including the cost of paying interest on the Series 1997 
Bonds at the expected interest rate and all fees associated with the Letter 
of Credit or any other type of credit enhancement) would be less than the 
cost of paying interest on the Series 1997 Bonds if it is not so secured 
(using as a discount rate the yield to maturity on the Series 1997 Bonds 
being converted to a Long-Term Interest Rate and treating the fees paid and 
to be paid for the credit enhancement as interest on the Series 1997 Bonds).  
The Remarketing Agent is required in the event of a change from a Daily, 
Weekly or Commercial Paper Rate to a Long-Term Interest Rate to perform such 
analysis and, if present value savings would result under the above formula, 
must obtain the form of credit enhancement generating the greatest present 
value savings under the above formula.  The provisions of this paragraph 
shall not apply if (i) the Series 1997 Bonds bore interest at a Long-Term 
Interest Rate on the day before the effective date of the change or (ii) a 
Favorable Opinion of Tax Counsel stating that this paragraph need not be 
applied to such change is delivered to the Trustee.  In addition, if a 
Long-Term Interest Rate will be in

                                     -46-

<PAGE>

effect during the term of the current Letter of Credit, the Company may not 
furnish an alternate Letter of Credit with a stated expiration date earlier 
than the stated expiration date in the Letter of Credit then in effect.

    Upon delivery to the Trustee of an Alternate Letter of Credit conforming to
the requirements of this Section 5.01 and delivery of the opinions described in
Section 5.01(c), then the Trustee shall accept such Alternate Letter of Credit
and promptly surrender for cancellation the previously held Letter of Credit to
the issuer thereof in accordance with the terms of such Letter of Credit;
PROVIDED that no delivery of such Alternate Letter of Credit shall be effective
unless the Company has given written notice to the Trustee (a copy of which
shall be delivered to the Bank providing the current Letter of Credit) not less
than 45 days prior to such delivery of the Company's intention to provide for
delivery of such Alternate Letter of Credit and the anticipated date of such
delivery.  Upon receipt of such notice, the Trustee shall take all actions
necessary to call the Series 1997 Bonds for mandatory redemption as described
under the paragraph "MANDATORY REDEMPTION UPON DELIVERY OF AN ALTERNATE LETTER
OF CREDIT" in Section 8 of the Series 1997 Bonds on the Interest Payment Date
next preceding the proposed effective date of such Alternate Letter of Credit;
PROVIDED that the notice of such mandatory redemption shall state that it is
subject to rescission, and the Trustee shall rescind such notice (unless the
Series 1997 Bonds are then subject to mandatory redemption as described under
the paragraph "MANDATORY REDEMPTION UPON EXPIRATION OF LETTER OF CREDIT") if all
of the requirements of this Section 5.01(b) are not met on or before the
Interest Payment Date on which the Series 1997 Bonds are subject to mandatory
redemption as described under the paragraph "MANDATORY REDEMPTION UPON DELIVERY
OF AN ALTERNATE LETTER OF CREDIT" (in which case such mandatory redemption shall
not occur).  Nothing in this Section 5.01(b) shall be construed to modify the
provisions relating to the redemption as described under the paragraph
"MANDATORY REDEMPTION UPON EXPIRATION OF LETTER OF CREDIT" or Section 5.01(a).

    (c)  OPINIONS OF COUNSEL.  Any Alternate Letter of Credit or other credit
facility delivered to the Trustee must be accompanied by (1) a Favorable Opinion
of Tax Counsel as to the delivery of the Alternate Letter of Credit or other
facility; (2) an Opinion of Counsel stating that delivery of the Alternate
Letter of Credit or other facility is authorized under this

                                     -47-

<PAGE>

Indenture and complies with its terms; (3) an opinion of counsel to the 
issuer or provider of such Alternate Letter of Credit or other facility 
stating that such Alternate Letter of Credit or other facility is a legal, 
valid, binding and enforceable obligation of such issuer or obligor in 
accordance with its terms; (4) an Opinion of Counsel that payments made by 
the Bank of amounts drawn under the Alternate Letter of Credit will not be 
recoverable from the Bondholders as voidable preferences under the provisions 
of the U.S. Bankruptcy Code in the event of a bankruptcy or similar 
insolvency proceeding with respect to the Company or the City; and (5) 
evidence satisfactory to the Trustee that the unsecured indebtedness of the 
new Bank (or parent company of the new Bank) is rated by a Rating Agency at 
"A-1/P-1", or, if a Favorable Opinion of Tax Counsel is delivered with 
respect to a different rating, some other rating.  In addition, if the 
Company or any natural person, firm, association or public body related to 
the Company within the meaning of Section 147(a) of the Code grants a 
security interest in any cash, securities or investment type property to the 
issuer or provider of such Letter of Credit or other facility, the Company 
must furnish the Trustee a Favorable Opinion of Tax Counsel with respect to 
such grant.

    SECTION 5.02.  DRAWS.  Whenever any amount is payable on the Series 1997
Bonds or for their purchase as provided in this Indenture or the Series 1997
Bonds, the Trustee will draw on the Letter of Credit to the extent necessary to
make such full and timely payment of principal and interest when due, whether on
an Interest Payment Date, at maturity, upon redemption, acceleration or
otherwise, in accordance with this Indenture, the Series 1997 Bonds and the
Letter of Credit, except that the Trustee may not draw on the Letter of Credit
to pay Series 1997 Bonds held by the Trustee for the benefit of the Bank in
accordance with Section 3.08(a)(3).  In drawing on the Letter of Credit, the
Trustee will be acting on behalf of the Bondholders by facilitating payment of
their Series 1997 Bonds and not on behalf of the City or Company and will not be
subject to the control of either.

    Upon receiving notice of a tender, or upon the date Series 1997 Bonds are
to be purchased by the Company in lieu of redemption, the Trustee promptly shall
draw on the Letter of Credit, in accordance with its terms, on the date fixed
for any such purchase, an amount to the end that

                                     -48-

<PAGE>

immediately available funds in Chicago, Illinois will be provided on such 
date from such draw to pay the purchase price.  No such drawing need be made 
to the extent that the Trustee has received telephone notice from the 
Remarketing Agent, promptly confirmed in writing, that such Series 1997 Bonds 
have been remarketed and the remarketing proceeds (that meet the requirements 
of Section 4.02, clause FIRST) on hand are sufficient to pay the purchase 
price of such Series 1997 Bonds.

                                   ARTICLE VI

                                   COVENANTS

    SECTION 6.01.  PAYMENT OF BONDS.  The City shall promptly pay the principal
of, and the premium, if any, and interest on, the Bonds on the dates and in the
manner provided in the Bonds, but only from the amounts assigned to and held by
the Trustee under this Indenture.

    SECTION 6.02.  FURTHER ASSURANCES.  The City shall execute and deliver such
supplemental indentures and such further instruments, and do such further acts,
as the Trustee may reasonably require for the better assuring, assigning and
confirming to the Trustee the amounts assigned under this Indenture for the
payment of the Bonds.

    SECTION 6.03.  REBATE FUND.  (a) The Trustee shall establish and maintain a
fund separate from any other fund established and maintained under this
Indenture designated as the "Rebate Fund."  Within the Rebate Fund, the Trustee
shall maintain such accounts as shall be necessary in order to comply with the
terms and requirements of the Tax Agreement.  Subject to the transfer provisions
provided in paragraph (e) below, all money at any time deposited in the Rebate
Fund shall be held by the Trustee in trust, to the extent required pursuant to
the Tax Agreement, for payment to the federal government of the United States of
America, and neither the City, the Company, the Bank nor the owner of any Bonds
shall have any rights or claim to such money.  All amounts deposited into or on
deposit in the Rebate Fund shall be governed by this Section, by Section 6.04
and by the Tax Agreement.

                                     -49-

<PAGE>

    (b)  Upon the Company's written direction, an amount shall be deposited to
the Rebate Fund by the Trustee from deposits by the Company or from available
investment earnings on amounts held under this Indenture and available for this
purpose, if and to the extent required, so that the balance of the amount on
deposit thereto shall be equal to the amount required by the Tax Agreement. 
Computations of the amount required to be deposited into the Rebate Fund shall
be furnished by or on behalf of the Company in accordance with the Tax
Agreement.

    (c)  The Trustee shall have no obligation to rebate any amounts required to
be rebated pursuant to this Section, other than from moneys held in the funds
and accounts created under this Indenture or from other moneys provided to it by
the Company.

    (d)  The Trustee shall invest all amounts held in the Rebate Fund as set
forth in the Tax Agreement.  Money shall not be transferred from the Rebate Fund
except as provided in paragraph (e) below.

    (e)  Upon receipt of the Company's written directions, the Trustee shall
remit part or all of the balances in the Rebate Fund to the United States, as so
directed.  In addition, if the Company so directs, the Trustee will deposit
moneys into or transfer moneys out of the Rebate Fund from or into such accounts
or funds as directed by the Company's written directions.  Any funds remaining
in the Rebate Fund after payment of all of the Bonds and payment and
satisfaction of any amount required to be paid pursuant to the Tax Agreement, or
provision made therefor satisfactory to the Trustee, shall be withdrawn and
remitted to the Company.

    (f)  Notwithstanding any other provision of this Indenture, including in
particular Article VII, the obligation to remit the amounts required to be paid
pursuant to the Tax Agreement to the United States and to comply with all other
requirements of this Section and Section 6.04 and the Tax Agreement shall
survive the discharge of the lien of this Indenture or payment in full of the
Bonds.

    SECTION 6.04.  TAX COVENANTS.  The City shall not knowingly take or omit to
take any action within its control, to the extent permitted by law,

                                     -50-

<PAGE>

that would cause the Series 1997 Bonds to be "arbitrage bonds" within the 
meaning of Section 148(a) of the Code.  

    As long as Series 1997 Bonds are outstanding, the City hereby covenants for
the benefit of the Beneficial Owners that it will, solely at the Company's
expense, (a) take any action which, in the opinion delivered to City and Company
of nationally recognized bond counsel acceptable to the City and the Company, is
necessary to preserve the exclusion of interest on the Series 1997 Bonds from
federal gross income and (b) refrain from taking any action which, in the
opinion delivered to City and Company of nationally recognized bond counsel
acceptable to the City and the Company, would adversely affect the exclusion of
interest on the Series 1997 Bonds from federal gross income.

    Notwithstanding any provision of this Section, if the Company provides to
the Trustee and the City an Opinion of Tax Counsel to the effect that any action
required under this Section is no longer required, or to the effect that some
further action is required, to maintain the exclusion of interest on the Series
1997 Bonds from federal gross income, the Trustee and the City may conclusively
rely on such opinion in complying with the provisions of this Section, and the
covenants under this Section shall be deemed to be modified to that extent.

                              ARTICLE VII

                         DISCHARGE OF INDENTURE

    Any Bond shall be deemed paid for all purposes of this Indenture when
(a) payment of the principal of and premium, if any, and interest on such Bond
to the due date of such principal and interest (whether at maturity, upon
redemption or otherwise) either (1) has been made in accordance with the terms
of the Bonds or (2) has been provided for by irrevocably depositing with the
Trustee (A) moneys sufficient to make such payment (PROVIDED that with respect
to Series 1997 Bonds while a Letter of Credit is in effect, such moneys shall
have been derived from the proceeds of a draw under such Letter of Credit)
and/or (B) U.S. Government Obligations (PROVIDED that with respect to the Series
1997 Bonds while a Letter of Credit is in effect, they have been purchased with
moneys derived from the

                                   -51-

<PAGE>

proceeds of a draw under such Letter of Credit) maturing as to principal and 
interest in such amounts and at such times as will assure the availability of 
sufficient moneys to make such payment (PROVIDED that with respect to Series 
1997 Bonds, such deposit under this clause (2) is made during a Commercial 
Paper Rate Period or a Long-Term Interest Rate Period), and (b) all 
compensation and reasonable expenses of the Trustee pertaining to such Bond 
have been paid or provided for to the Trustee's satisfaction.  When a Bond is 
deemed paid, it will no longer be secured by or entitled to the benefits of 
this Indenture, except for payment from moneys or U.S. Government Obligations 
under clause (a)(2) above and except that it may be tendered as provided in 
the Bonds and transferred, exchanged or replaced as provided in Article II.

    "U.S. GOVERNMENT OBLIGATIONS" means (i) noncallable direct obligations of
the United States of America for which its full faith and credit are pledged,
(ii) noncallable obligations of a person controlled or supervised by and acting
as an agency or instrumentality of the United States of America, the payment of
which is unconditionally guaranteed as a full faith and credit obligation of the
United States of America, or (iii) securities or receipts evidencing ownership
interests in obligations or specified portions (such as principal or interest)
of obligations described in clause (i) or (ii).

    Notwithstanding the first paragraph of this Section 7.01, in the case of
any Bond which by its terms may be redeemed prior to the Maturity Date, no
deposit under clause (a)(2) thereof shall be deemed a payment of such Bond until
the Company has furnished the Trustee (a) an Opinion of Tax Counsel stating that
such deposit will not cause the Bonds to become "arbitrage bonds" under Section
148 of the Code and (b) irrevocable instructions in form satisfactory to the
Trustee:

         (i)  stating the date when the principal (and premium, if any) of such
    Bond is to be paid, whether at maturity or on a redemption date;

         (ii) if such Bond is to be redeemed pursuant to this Indenture, to
    call such Bond for redemption; and

                                   -52-

<PAGE>

         (iii)     to mail, as soon as practicable, in the manner prescribed by
    Article III, a notice to the Owner of such Bond that the deposit required
    by clause (a)(2) of the first paragraph of this Section has been made with
    the Trustee and that such Bond is deemed to have been paid in accordance
    with this Section and stating the maturity or redemption date upon which
    moneys are to be available for the payment of such Bond or of its
    redemption price.

In addition, if the Bonds are to be rated by either Rating Agency on and after
the date of such deposit, the Company shall furnish to the Trustee a letter from
all such Rating Agencies to the effect that such deposit will not cause the
current rating on the Bonds to be reduced or withdrawn.

    When all Outstanding Bonds are deemed paid under the provisions of this
Section, the Trustee shall, upon request, acknowledge the discharge of the lien
of this Indenture; PROVIDED, HOWEVER, that the obligations under Article II in
respect of the transfer, exchange and replacement of Bonds shall survive the
discharge of the lien of this Indenture.

    SECTION 7.02.  APPLICATION OF TRUST MONEYS.  The Trustee shall hold in
trust moneys or U. S. Government Obligations deposited with it pursuant to
Section 7.01 and shall apply such moneys and the money derived from such U.S.
Government Obligations in accordance with this Indenture only to the payment of
the principal of, and the premium, if any, and interest on, the Bonds.

    SECTION 7.03.  REPAYMENT TO BANK AND COMPANY.  The Trustee shall promptly
pay to the Bank (to the extent the Bank certifies to the Trustee that the
Company is indebted to it under the Reimbursement Agreement) and then to the
Company, upon request, any excess moneys or securities held by the Trustee at
any time under this Article VII and any money held by the Trustee under any
other provision of this Indenture for the payment of principal, premium, if any,
or interest on the Bonds that remains unclaimed for two years.

                             ARTICLE VIII

                        DEFAULTS AND REMEDIES


    SECTION 8.01.  EVENTS OF DEFAULT.  An "EVENT OF DEFAULT" is any of the
following:

         (a)  Default in the payment of any interest on any Bond when due and
    payable.

         (b)  Default in the payment of principal or premium on any Bond when
    due and payable, whether at maturity, upon redemption, by declaration or
    otherwise.

         (c)  Default in the due and punctual payment of the purchase price of
    any Bond tendered by its Beneficial Owner pursuant to the Series 1997
    Bonds.

         (d)  The City fails to perform any of its agreements in this Indenture
    or the Bonds (except a failure that results in an Event of Default under
    clause (a), (b) or (c) above), the performance of which is material to the
    Bondholders, and the failure continues after the notice and for the period
    specified in this Section.

         (e)  The Company fails to perform any of its agreements in the Loan
    Agreement (except a failure that results in an Event of Default under
    clause (a), (b) or (c) of this Section or a failure under Section 5.4 or
    Section 5.5 of the Loan Agreement, relating to the impairment of the
    exclusion of interest on the Bonds from federal gross income), and the
    failure continues after the notice and for the period specified in this
    Section, PROVIDED that such a failure (other than a failure to perform an
    agreement in Section 5.6 of the Loan Agreement, relating to maintenance of
    the Company's existence) is not an Event of Default if it is a result of
    any cause or event not reasonably within the Company's control.

         (f)  The Company pursuant to or within the meaning of any Bankruptcy
    Law (1) commences a voluntary case, (2) consents to the

                                   -54-

<PAGE>

    entry of an order for relief against it in an involuntary case, (3) 
    consents to the appointment of a Custodian for the Company or any 
    substantial part of its property or (4) makes a general assignment for 
    the benefit of its creditors.

         (g)  A court of competent jurisdiction enters an order or decree under
    any Bankruptcy Law that (1) is for relief against the Company in an
    involuntary case, (2) appoints a Custodian for the Company or any
    substantial part of its property or (3) orders the winding up or
    liquidation of the Company, and the decree or order remains unstayed and in
    effect for 60 days.

         (h)  The Trustee receives written notice from the Bank that an "event
    of default" has occurred and is continuing (all periods for curing such
    default having expired without a cure having been made) under the
    reimbursement agreement pursuant to which the Letter of Credit was issued
    and a direction to accelerate the Bonds.

         (i)  The Trustee receives written notice from the Bank on or before
    the date or dates specified in the Letter of Credit following a drawing on
    the Letter of Credit to pay interest on the Bonds that it will not
    reinstate its Letter of Credit.

    "BANKRUPTCY LAW" means Title 11 of the United States Code or any similar
federal or state law for the relief of debtors.  "CUSTODIAN" means any receiver,
trustee, assignee, liquidator, custodian or similar official under any
Bankruptcy Law.

    A default under clause (d) or (e) of this Section is not an Event of
Default until the Trustee or the holders of at least 25 percent in principal
amount of the Bonds then outstanding give the City and the Company a notice
specifying the default, demanding that it be remedied and stating that the
notice is a "Notice of Default," and the City (if the default is under clause
(d)) or the Company (if the default is under clause (e) or if the default is
under clause (d) and the Company has elected to perform the City's agreements
under this Indenture and the Bonds as described in the last sentence of this
paragraph) does not cure the default within 90 days after receipt of the notice,
or within such longer period as the Trustee shall agree

                                   -55-

<PAGE>

to.  The Trustee shall not unreasonably refuse to agree to a longer period if 
the default can be cured but cannot reasonably be cured within 90 days after 
receipt of the notice and the City or the Company has begun within 90 days 
and continued diligent efforts to correct the default.  The City authorizes 
the Company to perform, in the name and on behalf of the City and for the 
purpose of preventing the occurrence of an Event of Default, any agreement of 
the City in this Indenture or the Bonds.

    SECTION 8.02.  ACCELERATION.  If an Event of Default under clause (h) or
(i) of the foregoing Section occurs and is continuing, the Trustee shall declare
the principal and accrued interest to the date of declaration of acceleration on
the Bonds to be due and payable immediately and at such time interest on the
Bonds shall cease to accrue.  If any other Event of Default occurs and is
continuing, the Trustee by notice to the City and the Company, or the holders of
at least 25 percent in principal amount of the Bonds then outstanding by notice
to the City, the Company and the Trustee (except for an Event of Default under
clause (f) or (g) of the foregoing Section, for which a declaration can be made
without any notice) may declare the principal of and accrued interest on the
Bonds to the date of declaration of acceleration of the Bonds to be due and
payable immediately.  Upon any declaration of acceleration, the Trustee shall
immediately exercise such rights as it may have under the Loan Agreement.  

    If a Letter of Credit is in effect, if the Event of Default is not under
clause (h) or (i) of the foregoing Section and is not the result of a failure by
the Bank to honor a draw on the Letter of Credit, the Trustee will not declare
the Series 1997 Bonds to be due and payable or pursue any other remedy without
first obtaining the Bank's consent.  Upon a declaration that the principal of
and accrued interest on the Series 1997 Bonds shall be due and payable, the
Trustee shall immediately draw on the Letter of Credit to pay the principal of
and accrued interest on the Series 1997 Bonds.  The Trustee shall immediately
give notice of acceleration to the Bondholders.

    The Trustee may, and upon the request of holders of a majority in principal
amount of the affected Bonds then outstanding shall, rescind an acceleration and
its consequences if all existing Events of Default have been cured or waived,
and (a) with respect to the Series 1997 Bonds, if, when a Letter of Credit is in
effect, the Bank gives its written consent to the waiver

                                   -56-

<PAGE>

of the event of default under the Reimbursement Agreement and gives notice in 
writing that the Letter of Credit has not expired in accordance with its 
terms and that the Letter of Credit is reinstated up to an amount equal to 
the principal of all outstanding Series 1997 Bonds and (except during a 
Commercial Paper Mode or a Long-Term Interest Rate Period) up to 45 days' 
interest accrued on the Series 1997 Bonds at a maximum rate of 12 percent; 
(b) the rescission would not conflict with any judgment or decree; and (c) 
all payments due the Trustee and any predecessor Trustee under Section 9.06 
have been made.

    SECTION 8.03.  OTHER REMEDIES.  If an Event of Default has occurred and is
continuing, the Trustee may pursue any available remedy by proceeding at law or
in equity to collect the principal of, and the premium, if any, and interest on,
the Bonds or to enforce the performance of any provision of the Bonds, this
Indenture or the Loan Agreement.

    The Trustee, as the assignee of certain rights, titles and interests of the
City in and to the Loan Agreement, may enforce each and every right, title and
interest so assigned.

    The Trustee may maintain a proceeding even if it does not possess any of
the Bonds or does not produce any of them in the proceeding.  A delay or
omission by the Trustee or any Bondholder in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in such Event of Default.  No remedy is
exclusive of any other remedy.  All available remedies are cumulative.

    SECTION 8.04.  WAIVER OF PAST DEFAULTS.  The Owners of not less than a
majority in aggregate principal amount of the Bonds then Outstanding together,
when a Letter of Credit is in effect, with the Bank, by notice to the Trustee
and the Company, may waive an Event of Default and its consequences if the
Letter of Credit is reinstated up to the amount specified in Section 5.01 and
the Bank has waived in writing all defaults under the reimbursement agreement
pursuant to which the Letter of Credit was issued, but taking into account Bonds
held for the account of the Bank.  When an Event of Default is waived, it is
cured and stops continuing, but no

                                   -57-

<PAGE>

such waiver shall extend to any subsequent or other Event of Default or impair
any right consequent to it.

    SECTION 8.05.  CONTROL BY MAJORITY.  Subject to Section 9.01, the Owners of
not less than a majority in aggregate principal amount of the Bonds then
Outstanding may direct the time, method and place of conducting any proceeding
for any remedy available to the Trustee or of exercising any trust or power
conferred on it.  However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture.  During any period when the Bonds are
secured by a Letter of Credit and the Bank has honored draws on the Letter of
Credit, any such direction of the Owners shall be followed by the Trustee only
with the prior written consent of the Bank.  

    SECTION 8.06.  LIMITATION ON SUITS.  A Bondholder may not pursue any remedy
with respect to this Indenture or the Bonds unless (a) such Owner gives the
Trustee notice stating that an Event of Default is continuing, (b) the Owners of
at least 25 percent in aggregate principal amount of the Bonds then Outstanding
make a written request to the Trustee to pursue such remedy, (c) such Owner or
Owners offer to the Trustee indemnity satisfactory to the Trustee against any
loss, liability or expense incurred in connection therewith and (d) the Trustee
does not comply with such request within 60 days after receipt of such request
and offer of indemnity.

    A Bondholder may not use this Indenture to prejudice the rights of another
Bondholder or to obtain a preference or priority over any other Bondholder.

    SECTION 8.07.  RIGHTS OF OWNERS TO RECEIVE PAYMENT.  Notwithstanding any
other provision of this Indenture, the right of any Owner to receive payment of
the principal of, and premium, if any, and interest on, a Bond, on or after the
due dates expressed in such Bond, or the purchase price of a Bond on or after
the date for its purchase as provided in such Bond, or to bring suit for the
enforcement of any such payment on or after such dates, shall not be impaired or
affected without the consent of such Owner.

                                   -58-

<PAGE>

    SECTION 8.08.  COLLECTION SUIT BY TRUSTEE.  If an Event of Default under
Section 8.01(a), (b) or (c) has occurred and is continuing, the Trustee may
recover judgment in its own name and as trustee of an express trust against the
Company for the whole amount remaining unpaid.

    SECTION 8.09.  TRUSTEE MAY FILE PROOFS OF CLAIM.  The Trustee may file such
proofs of claim and other papers or documents as may be necessary or advisable
in order to have the claims of the Trustee and the Bondholders allowed in any
judicial proceedings relative to the Company or the Bank, their creditors or
their property and, unless prohibited by law or applicable regulations, may vote
on behalf of the Owners in any election of a trustee in bankruptcy or other
person performing similar functions.  In the event of a bankruptcy or
reorganization of the Company, the Trustee may file a proof of claim on behalf
of all Bondholders with respect to the obligations of the Company pursuant to
the Loan Agreement.

    SECTION 8.10.  PRIORITIES.  If the Trustee collects any money pursuant to
this Article VIII, it shall pay out such money as soon as practicable in the
following order:

         FIRST:    To the Trustee for amounts to which it is entitled under
    Section 9.06, but the Trustee may not pay itself for such amount from
    moneys drawn under the Letter of Credit;

         SECOND:   To the Bondholders for amounts due and unpaid on the Bonds
    for principal, premium, if any, and interest, ratably, without preference
    or priority of any kind, according to the amounts due and payable on the
    Bonds for principal, premium, if any, and interest, respectively;

         THIRD:    To the Bank to the extent the Bank certifies to the Trustee
    that the Company is indebted to the Bank under the Reimbursement Agreement;
    and

         FOURTH:   To the Company.

The Trustee may fix a payment date for any payment to the Bondholders.

                                   -59-

<PAGE>

    SECTION 8.11.  UNDERTAKING FOR COSTS.  In any suit for the enforcement of
any right or remedy under this Indenture or in any suit against the Trustee for
any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in such suit of an undertaking to pay
the costs of such suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys' fees, against any party litigant in such
suit, having due regard to the merits and good faith of the claims or defenses
made by the party litigant.  This Section does not apply to a suit by the
Trustee, a suit by an Owner pursuant to Section 8.07 or a suit by Owners of more
than 10 percent in  aggregate principal amount of the Bonds then Outstanding.

                        TRUSTEE AND REMARKETING AGENT


    SECTION 9.01.  DUTIES OF TRUSTEE.  (a) If an Event of Default has occurred
and is continuing, the Trustee shall exercise its rights and powers and use the
same degree of care and skill in their exercise as a prudent person would
exercise or use under the circumstances in the conduct of such person's own
affairs.

    (b)  Except during the continuance of an Event of Default:

         (1)  the Trustee need perform only those duties that are specifically
    set forth in this Indenture and applicable laws and regulations and no
    others and no implied duties or covenants shall be read into this Indenture
    against the Trustee, and

         (2)  in the absence of bad faith on its part, the Trustee may
    conclusively rely, as to the truth of the statements and the correctness of
    the opinions expressed, upon certificates, opinions, requisitions or any
    other writing furnished to the Trustee and conforming to the requirements
    of this Indenture.  However, the Trustee shall examine the same to
    determine whether they conform to the requirements of this Indenture.

                                   -60-

<PAGE>

    (c)  The Trustee shall not be relieved from liability for its own negligent
action, its own negligent failure to act or its own willful misconduct, except
that:

         (1)  this subsection (c) shall not limit the effect of subsection (b)
    of this Section 9.01;

         (2)  the Trustee shall not be liable for any error of judgment made in
    good faith by a Responsible Officer, unless it is proved that the Trustee

         (3)  the Trustee shall not be liable with respect to any action it
    takes or omits to take in good faith in accordance with a direction
    received by it pursuant to Section 8.05; and

         (4)  no provision of this Indenture shall require the Trustee to
    expend or risk its own funds or otherwise incur any financial liability in
    the performance of any of its duties hereunder or in the exercise of any of
    its rights or powers hereunder, if it shall have reasonable grounds for
    believing that repayment of such funds or adequate indemnity against such
    risk or liability is not reasonably assured to it.

    (d)  Every provision of this Indenture that in any way relates to the
Trustee is subject to all the provisions of this Section 9.01.

    (e)  The Trustee may refuse to perform any duty or exercise any right or
power unless it receives indemnity satisfactory to it against any loss,
liability or expense, but the Trustee may not require indemnity as a condition
to declaring the principal of and interest on the Bonds to be due immediately
under Section 8.02, to drawing on the Letter of Credit or to making any payment
of principal, premium or interest on the Series 1997 Bonds.

    (f)  The Trustee shall not be liable for interest on any cash held by it,
except as the Trustee may agree with the Company or the City with the consent of
the Company.

                                   -61-

    (g)  The Trustee may rely on a Company Representative's certificate as to
whether a Bankruptcy Filing has occurred.

    (h)  In addition to the funds and accounts established by this Indenture,
the Trustee may establish such funds and accounts as it deems necessary and
appropriate in order to discharge its duties under this Indenture.

    (i)  The Trustee, on behalf of the City, shall appoint an authenticating
agent acceptable to the Company to authenticate Bonds if required pursuant to
Section 9.07.  An authenticating agent may authenticate Bonds whenever the
Trustee may do so.  Each reference in this Indenture to authentication by the
Trustee shall include authentication by such authenticating agent.

    SECTION 9.02.  RIGHTS OF TRUSTEE.   Subject to Section 9.01:

         (a)  The Trustee may rely on any document believed by it to be genuine
    and to have been signed or presented by the proper person.  The Trustee
    need not investigate any fact or matter stated in such document.

         (b)  The Trustee shall not be liable for any action it takes or omits
    to take in good faith in reliance on any certificate of an appropriate
    officer or officers of the City or the Company or any Opinion of Counsel.

         (c)  The Trustee may act through agents or, as provided in Section
    9.16, through co-trustees so long as each such co-trustee shall agree in
    writing to be bound by the standards of conduct for the Trustee specified
    in this Indenture, and the Trustee shall not be responsible for the willful
    misconduct or negligence of any agent or co-trustee appointed by it with
    due care.

    SECTION 9.03.  INDIVIDUAL RIGHTS OF TRUSTEE.  The Trustee in its individual
or any other capacity may become the Owner or a pledgee of Bonds and may
otherwise deal with the City or with the Company or its affiliates with the same
rights it would have if it were not the Trustee.

                                   -62-

<PAGE>

    SECTION 9.04.  TRUSTEE'S DISCLAIMER.  The Trustee makes no representation
as to the validity or adequacy of this Indenture, the Loan Agreement or the
Bonds, except for its execution hereof and its authentication of any Bond
hereunder.  The Trustee shall not be accountable for the Company's use of Bond
proceeds, nor shall it be responsible for any statement in the Bonds other than
its certificate of authentication.

    SECTION 9.05.  NOTICE OF DEFAULTS.  If an event occurs which, with the
giving of notice or lapse of time or both, would become an Event of Default, and
if such event is continuing and is known to the Trustee, the Trustee shall mail
to the City and to each Bondholder notice of such event within 90 days after it
occurs. Except in the case of a default in the payment or purchase on any Bonds,
the Trustee may withhold such notice from the Bondholders if and so long as a
committee of its Responsible Officers in good faith determines that withholding
such notice is in the best interests of the Bondholders.

    SECTION 9.06.  COMPENSATION OF TRUSTEE.  For acting under this Indenture,
the Trustee shall be entitled to payment as previously agreed upon in writing by
the Company and the Trustee.

    To secure the payment or reimbursement to the Trustee provided for in this
Section, the Trustee shall have a senior claim, to which the Bonds are made
subordinate, on all money or property held or collected by the Trustee, except
any money or property held under Section 4.04 or Article VII or otherwise held
in trust to pay the principal of, and the premium, if any,  and interest on, or
the purchase price of, particular Bonds and except amounts drawn under the
Letter of Credit.

    SECTION 9.07.  ELIGIBILITY OF TRUSTEE.  This Indenture shall always have a
Trustee that is a corporation or association organized and doing business under
the laws of the United States of America or any state or the District of
Columbia, is authorized under such laws to exercise corporate trust powers, is
subject to supervision or examination by United States of America, state or
District of Columbia authority and has a combined capital, surplus and undivided
profits of at least $10,000,000 as set forth in its most recent published annual
report of condition.  If at any time the Trustee ceases to be eligible in
accordance with this Section, the Trustee shall resign

                                   -63-

<PAGE>

immediately as set forth in Section 9.08.  If the Bonds are then rated by 
Moody's Investors Service, Inc., any successor Trustee shall be rated at 
least Baa3/P-3 or otherwise be acceptable to Moody's Investors Service, Inc.

    SECTION 9.08.  REPLACEMENT OF TRUSTEE.  (a) The Trustee may resign by
notifying the City and the Company in writing and by mailing notice thereof by
first-class mail to the Bondholders.

    Upon receiving such notice of resignation, the Company, with the consent of
the City, shall promptly appoint a successor trustee by an instrument in
writing; PROVIDED that the Company may not make such appointment if an Event of
Default has occurred and is continuing, or if an event has occurred and is
continuing which, with the giving of notice or lapse of time or both, would
become an Event of Default.  If no successor trustee shall have been so
appointed and have accepted appointment within 30 days after the giving of such
notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction for the appointment of a successor trustee or any Bondholder who
has been a bona fide Owner of a Bond for at least six months may, on behalf of
himself and all others similarly situated, petition any such court for the
appointment of a successor trustee.  Such court may thereupon, after such
notice, if any, as it may deem proper and may prescribe, appoint a successor
trustee.

    (b)  In case at any time either of the following shall occur:

         (1)  the Trustee shall cease to be eligible in accordance with the
    provisions of Section 9.07 and shall fail to resign after written request
    therefor by the Company, the City or any Bondholder who has been a bona
    fide Owner of a Bond for at least six months, or

         (2)  the Trustee shall become incapable of acting, or shall be
    adjudged a bankrupt or insolvent, or a receiver of the Trustee or of its
    property shall be appointed, or any public officer shall take charge or
    control of the Trustee or of its property or affairs for the purpose of
    rehabilitation, conservation or liquidation, 

                                   -64-

<PAGE>

then, in any such case, the Company shall remove the Trustee and appoint a
successor trustee by an instrument in writing; PROVIDED that the Company may not
make such appointment if an Event of Default has occurred and is continuing, or
if an event has occurred and is continuing which, with the giving of notice or
lapse of time or both, would become an Event of Default, in which case the
successor trustee shall be appointed by a court as provided in subsection (a) of
this Section.

    (c)  Owners of a majority in aggregate principal amount of the Bonds at the
time Outstanding may at any time remove the Trustee by an instrument or
concurrent instruments in writing signed by such Bondholders and delivered to
the Trustee and the Company.  Upon receiving such notice of removal, the Company
shall promptly appoint a successor trustee by an instrument in writing; PROVIDED
that the Company may not make such appointment if an Event of Default has
occurred and is continuing, or if an event has occurred and is continuing which,
with the giving of notice or lapse of time or both, would become an Event of
Default, in which case the successor trustee shall be appointed by a court as
provided in subsection (a) of this Section.  

    (d)  Any resignation or removal of the Trustee and the appointment of a
successor trustee pursuant to any of the provisions of this Section shall become
effective only upon acceptance of appointment by the successor trustee as
provided in Section 9.09.  The Company shall give written notification to any
Rating Agency then rating the Bonds if a successor trustee shall be appointed
pursuant to this Section.

    SECTION 9.09.  ACCEPTANCE OF TRUST BY SUCCESSOR TRUSTEE.  Any successor
trustee appointed as provided in Section 9.08 shall execute, acknowledge and
deliver to the City and to its predecessor trustee an instrument accepting such
appointment hereunder, and thereupon the resignation or removal of the
predecessor trustee shall become effective and such successor trustee, without
any further act, deed or conveyance, shall become vested with all the rights,
powers, trusts, duties and obligations of its predecessor in the trusts
hereunder, with like effect as if originally named as Trustee herein; but,
nevertheless, on the written request of the City or the written request of the
successor trustee, the Trustee ceasing to act shall execute and deliver an
instrument transferring to such successor

                                   -65-

<PAGE>

trustee, upon the trusts herein expressed, all the rights, powers and trusts 
of the Trustee so ceasing to act. Upon request of any such successor trustee, 
the City shall execute any and all instruments in writing necessary or 
desirable for more fully and certainly vesting in and confirming to such 
successor trustee all such rights, powers and trusts.  Any Trustee ceasing to 
act shall, nevertheless, retain a lien upon all property or funds held or 
collected by such Trustee to secure the amounts due it as compensation, 
reimbursement, expenses and indemnity afforded to it by Section 9.06.

    No successor trustee shall accept appointment as provided in this Section
unless at the time of such acceptance such successor trustee shall be eligible
under the provisions of Section 9.07.

    At the time of appointment, the Company and the successor trustee shall
execute an agreement with respect to the compensation of the successor trustee.

    Upon acceptance of appointment by a successor trustee as provided in this
Section, the City or such successor trustee shall give the Bondholders notice of
the succession of such trustee to the trusts hereunder in the manner prescribed
in Section 9.08 for the giving of notice of resignation of the Trustee.

    SECTION 9.10.  DUTIES OF REMARKETING AGENT.  The Remarketing Agent shall
set the interest rates on the Series 1997 Bonds and perform the other duties
provided for in Section 2.02 and will remarket Series 1997 Bonds as provided in
Section 3.08, subject to any provisions of the Remarketing Agreement, which
shall control in the case of any conflict with this Indenture.  So long as the
Series 1997 Bonds are held in the Book-Entry System, the Remarketing Agent must
be the sole Participant in such system with respect to the Series 1997 Bonds,
except under the circumstances described in Section 3.08(3).  The Remarketing
Agent may for its own account or as broker or agent for others deal in the Bonds
and may do anything any other Bondholder may do to the same extent as if the
Remarketing Agent were not serving as such.

    SECTION 9.11.  ELIGIBILITY OF REMARKETING AGENT.  The initial Remarketing
Agent appointed under this Indenture is First National Bank of

                                   -66-

<PAGE>

Chicago, Chicago, Illinois.  The Remarketing Agent shall be a bank, trust 
company or member of the National Association of Securities Dealers, Inc. 
organized and doing business under the laws of the United States of America 
or any state or the District of Columbia, shall have a combined capital 
stock, surplus and undivided profits of at least $15,000,000 as set forth in 
its most recent published annual report and shall be authorized by law to 
perform all the duties imposed upon the Remarketing Agent by this Indenture 
and the Remarketing Agreement.  If the Series 1997 Bonds are then rated by 
Moody's Investors Service, Inc., any successor Remarketing Agent shall be 
rated at least Baa3/P-3 or otherwise be acceptable to Moody's Investors 
Service, Inc.

    SECTION 9.12.  REPLACEMENT OF REMARKETING AGENT.  The Remarketing Agent may
resign by notifying the City, the Trustee and the Company.  Such resignation
will take effect only on the day a successor Remarketing Agent appointed in
accordance with this Section has accepted the appointment.  The Company may
remove the Remarketing Agent at any time by an instrument signed by the Company
and delivered to the Remarketing Agent, the City and the Trustee at least 30
days prior to the effective date of such removal (which shall not in any event
occur prior to the appointment of a successor Remarketing Agent).  A new
Remarketing Agent may be appointed by the Company with the consent of the City
upon the resignation or removal of the Remarketing Agent.  The Trustee shall
promptly notify the holders of Series 1997 Bonds and all Rating Agencies of any
change in the Remarketing Agent.

    SECTION 9.13.  COMPENSATION OF REMARKETING AGENT.  The Remarketing Agent
shall not be entitled to any compensation from the City, the Trustee or any
property held under this Indenture but must make separate arrangements with the
Company for compensation.

    SECTION 9.14.  SUCCESSOR TRUSTEE OR REMARKETING AGENT BY MERGER.  If the
Trustee or the Remarketing Agent consolidates with, merges or converts into, or
transfers all or substantially all its assets (or, in the case of a bank or
trust company, its corporate trust assets) to, another corporation, the
resulting, surviving or transferee corporation without any further act shall be
the successor Trustee or Remarketing Agent, PROVIDED

                                   -67-

<PAGE>

that such successor shall be eligible under the applicable provisions of 
this Article IX.

    SECTION 9.15.  SEPARATE OR CO-TRUSTEE.  It is the purpose of this Indenture
that there shall be no violation of any law of any jurisdiction (including
particularly the laws of the State) denying or restricting the right of banking
corporations or associations to transact business as trustee in such
jurisdiction.  It is recognized that in the case of litigation under this
Indenture, and in particular in the case of the enforcement of this Indenture
upon the occurrence of an Event of Default, or in case the Trustee deems that by
reason of any present or future law of any jurisdiction it may not exercise any
of the rights, powers, trusts or remedies herein granted to the Trustee or hold
title to the trust estate, as herein granted and described in the Granting
Clause, or take any other action which may be desirable or necessary in
connection therewith, it may be necessary or desirable for the Trustee to
appoint an individual or institution as a separate or co-trustee.  The Trustee
is hereby authorized to appoint a separate or co-trustee under such
circumstances, and the following provisions of this Section shall apply to any
separate or co-trustee so appointed.

    In the event that the Trustee appoints an individual or institution as a
separate or co-trustee, each and every right, power, trust, remedy, estate,
title, interest, claim, cause of action and lien expressed or intended by this
Indenture to be exercised by or vested in or conveyed to the Trustee shall be
exercisable by and vested in such separate or co-trustee, but only to the extent
necessary to enable the separate or co-trustee to exercise such rights, powers,
trusts and remedies.

    Should any deed, conveyance or instrument in writing from the City be 
reasonably required by any separate trustee or co-trustee so appointed by the 
Trustee for more fully and certainly vesting in and confirming to him or it 
such estates, rights, powers, trusts, duties and obligations, any and all 
such deeds, conveyances and instruments in writing shall, on request, be 
executed, acknowledged and delivered by the City.  In case any separate 
trustee or co-trustee, or a successor to either, shall die, become incapable 
of acting, resign or be removed, all the estates, rights, powers, trusts, 
duties and obligations of such separate trustee or co-trustee, so far as 
permitted by

                                   -68-

<PAGE>

law, shall vest in and be exercised by the Trustee until the appointment of a 
successor, separate or co-trustee.

    Except as otherwise required by applicable law, no right or power granted
by this Indenture to any separate or co-trustee shall be exercised by such
separate or co-trustee alone unless such separate or co-trustee shall have
obtained the written consent of the Trustee to do so.

    The Trustee may at any time, by an instrument in writing executed by it,
remove any separate or co-trustee, and in such event may, in its discretion, by
an instrument in writing executed by it, appoint a successor to such separate or
co-trustee.

    the Series 1997 Bonds bear interest at a Daily Rate or a Weekly Rate and

    any amendment to the Code or interpretations by the Internal Revenue
    Service of the Code) that does not materially adversely affect the rights
    of any Bondholder; 

         (j)  to make any change necessary to secure from a Rating Agency a
    rating on the Series 1997 Bonds equal to the rating on the unsecured
    indebtedness of the Bank (or parent company of the Bank) or the issuer of
    any other type of credit enhancement; 

         (k)  to provide for the issuance of Additional Bonds; or 

         (l)  in connection with the extension of the maturity of the Series
    1997 Bonds as provided in Section 9 of the Series 1997 Bonds.  

                                   -70-

and may conclusively rely, on an Opinion of Counsel that such amendment or

supplement to this Indenture or the Bonds without the consent of Bondholders is
not permitted by Section 10.01, the City and the Trustee may enter into such
amendment or supplement with the consent of the Owners of at least a majority in
the aggregate principal amount of the Bonds then Outstanding.  However, without
the consent of each Bondholder affected, no amendment or supplement may (a)
extend the maturity of the principal of, or interest on, any Bond, (b) reduce
the principal amount of, or rate of interest on, any Bond (other than an
extension of the maturity of Series 1997 Bonds as provided in Section 9 of the
Series 1997 Bonds), (c) effect a privilege or priority of any Bond or Bonds over
any other Bond or Bonds, (d) reduce the percentage of the aggregate principal
amount of the Bonds the Owners of which are required to consent to such
amendment or supplement, (e) impair the exclusion from federal gross income of
interest on any Bond, (f) eliminate the Owners' rights to tender the Bonds or
any mandatory redemption of the Bonds, or extend the due date for the purchase
of Bonds tendered by the Owners thereof or any call date for mandatory
redemption, or reduce the purchase or redemption price of the Bonds, (g) create
a lien ranking prior to or on a parity with the lien of this Indenture on the
property described in the Granting Clause of this Indenture or (h) deprive any
Bondholder of the lien created by this Indenture on such property.  In addition,
if moneys or U.S. Government Obligations have been deposited or set aside with
the Trustee pursuant to Article VII for the payment of Bonds and such Bonds
shall not have in fact been actually paid in full, no amendment to the
provisions of such Article VII shall be made without the consent of the Owner of
each affected Bond.

    SECTION 10.03. EFFECT OF CONSENTS.  After an amendment or supplement
becomes effective, it will bind every Bondholder unless it makes a change
described in clauses (a) through (h) of the second sentence of Section 10.02, in
which case the amendment or supplement will bind each Bondholder who consented
to it and each subsequent Owner of a Bond or portion of a Bond evidencing the
same debt as the consenting Owner's Bond.

    SECTION 10.04. NOTATION ON OR EXCHANGE OF BONDS.  If an amendment or
supplement changes the terms of a Bond, the Trustee may require the Owner to
deliver such Bond to the Trustee.  The Trustee may place an appropriate notation
on such Bond about the changed terms and return it to the Owner.  Alternatively,
if the Trustee, the City and the Company so determine, the City, in exchange for
such Bond, shall execute and the Trustee shall authenticate and deliver a new
Bond that reflects the changed terms.

    SECTION 10.05. SIGNING BY TRUSTEE OF AMENDMENTS AND SUPPLEMENTS.  The
Trustee shall sign any amendment or supplement to this Indenture or the Bonds
authorized by this Article X if such amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee.  If such
amendment or supplement has such an adverse effect, the Trustee may, but need
not, sign it.  In signing such an amendment or supplement, the Trustee shall be
entitled to receive and (subject to Section 9.01) shall be fully protected in
relying on an Opinion of Counsel stating that such amendment or supplement is
authorized by this Indenture.

    SECTION 10.06. COMPANY AND BANK CONSENT REQUIRED.  No amendment or
supplement to this Indenture or the Bonds shall become effective unless the
Company and, when a Letter of Credit is in effect or any amounts are owed to the
Bank under the Reimbursement Agreement, the Bank deliver to the Trustee and to
the City their written consents to the amendment or supplement.

    SECTION 10.07. NOTICE TO BONDHOLDERS.  The Trustee shall cause notice of
the execution of each amendment or supplement to this Indenture or the Loan
Agreement to be mailed to the Bondholders by first-class mail.  The notice
shall, at the option of the Trustee, either (i) briefly state the nature of the
amendment or supplement and that copies of it are on file with the Trustee for
inspection by the Bondholders or (ii) enclose a copy of such amendment or
supplement.

    SECTION 11.01. WITHOUT CONSENT OF BONDHOLDERS.  The City may enter into,
and the Trustee may consent to, any amendment of or supplement to the Loan
Agreement without notice to or the consent of any Bondholder if such amendment
or supplement is required or permitted (a) by the provisions of the Loan
Agreement or this Indenture (including, in connection with transactions
permitted by Section 5.6 of the Loan Agreement, relating to maintenance of the
Company's existence), (b) to cure any ambiguity, inconsistency or formal defect
or omission, (c) to identify more precisely the Project, (d) in connection with
any authorized amendment of or supplement to this Indenture, (e) to make any
change that does not materially adversely affect the rights of any Bondholder,

Bonds equal to the rating on the unsecured indebtedness of the Bank (or the
parent company of the Bank) or the issuer of any other type of credit

complies with this Section. 

    SECTION 11.02. WITH CONSENT OF BONDHOLDERS.  If an amendment of or
supplement to the Loan Agreement without the consent of Bondholders is not
permitted by Section 11.01, the City may enter into, and the Trustee may consent
to, such amendment or supplement with the consent of the Owners of at least a
majority in the aggregate principal amount of the Bonds then Outstanding. 
However, without the consent of each Bondholder affected, no amendment or
supplement may result in any occurrence described in clauses (a) through (h) of
the second sentence of Section 10.02.

    SECTION 11.03. CONSENTS BY TRUSTEE TO AMENDMENTS OR SUPPLEMENTS.  The
Trustee shall consent to any amendment or supplement to the Loan Agreement

amendment or supplement has such an adverse effect, the Trustee may, but need
not, sign it.  In signing a consent

to such an amendment or supplement, the Trustee shall be entitled to receive

Opinion of Counsel stating that such amendment or supplement is authorized by 
this Indenture.

REGISTERED OWNER:  

<PAGE>

PRINCIPAL AMOUNT:  

    The City of Chicago, a home rule unit of local government, duly organized
and validly existing under the laws of the State of Illinois, in accordance with
the provisions of Section 6(a) of the 1970 Constitution of the State of
Illinois, hereby promises to pay, solely from the sources described in this
Bond, to the Registered Owner identified above, or registered assigns, on the
Maturity Date stated above or on the Maturity Date as it may be extended as
provided in Section 9 of this Bond (or if this Bond is called for earlier
redemption as described herein, on the redemption date) the principal amount
identified above and to pay interest and premium, if any, as provided in this
Bond.

    1.   INDENTURE; LOAN AGREEMENT.  This Bond is one of the bonds (the
"BONDS"), limited to $55,000,000 in aggregate principal amount, issued under the
Indenture of Trust dated as of September 1, 1997 (the "INDENTURE") between the
City of Chicago (the "CITY") and American National Bank and Trust Company of
Chicago, as trustee (the "TRUSTEE").  The terms of the Bonds include those in
the Indenture.  Bondholders are referred to the Indenture for a statement of
those terms.  The Indenture also provides for the issuance, under the
conditions, limitations and restrictions therein set forth, of additional series
of bonds on a parity with the Bonds and all other bonds issued under the
Indenture.  Capitalized terms used herein and not otherwise defined shall have
the meanings ascribed to them in the Indenture.

    The City will provide the proceeds of the Bonds to CenterPoint O'Hare,
L.L.C. an Illinois limited liability company (the "COMPANY"), pursuant to a Loan
Agreement dated as of September 1, 1997 (the "LOAN AGREEMENT") between the City
and the Company.  The Company will use the proceeds of the Bonds to pay a
portion of the costs of funding the designing, constructing, rehabilitating,
furnishing and equipping and leasing of air cargo facilities used for the
receiving and storing of cargo being transported at Chicago-O'Hare International
Airport (the "AIRPORT") and other incidental uses and other improvements related
to the operation of the Airport (the "PROJECT").  The Company has agreed in the
Loan Agreement to pay the City amounts sufficient to pay all amounts coming due
on the 


                                      A-2
<PAGE>

Bonds, and the City has assigned its right to such payments under the Loan 
Agreement to the Trustee as security for the Bonds.

    The Indenture and the Loan Agreement may be amended, and references to them
include any amendments.

    The City has established a book-entry only system of registration for the
Bonds (the "BOOK-ENTRY SYSTEM").  Except as specifically provided otherwise in
the Indenture, the Securities Depository (or its nominee) will be the Registered
Owner of this Bond.  By acceptance of a confirmation of purchase, delivery or
transfer, the Beneficial Owner of this Bond shall be deemed to have agreed to
this arrangement.  The Securities Depository (or its nominee), as Registered
Owner of this Bond, shall be treated as its owner for all purposes.

    2.   SOURCE OF PAYMENTS.  The Bonds are issued pursuant to and in full
compliance with the Constitution and laws of the State of Illinois and pursuant
to an ordinance adopted by the City on September 10, 1997, which ordinance
authorizes the execution and delivery of the Loan Agreement and the Indenture. 
The Bonds are limited obligations of the City and, as provided in the Indenture,
are payable solely from payments to be made by the Company under the Loan
Agreement, from a Letter of Credit as described below (but only so long as a
Letter of Credit is in effect) and from any other moneys held by the Trustee
under the Indenture for such purpose, and there shall be no recourse against the
City or any other property now or hereafter owned by it.  THE BONDS SHALL NOT
CONSTITUTE AN INDEBTEDNESS OF THE CITY OR A LOAN OF CREDIT THEREOF WITHIN THE
MEANING OF ANY CONSTITUTIONAL OR STATUTORY PROVISION OF THE STATE OF ILLINOIS. 
NEITHER THE FAITH AND CREDIT NOR THE TAXING POWER OF THE CITY, THE STATE OF
ILLINOIS OR ANY POLITICAL SUBDIVISION THEREOF, IS PLEDGED TO THE PAYMENT OF THE
PRINCIPAL OF THE BONDS, OR THE INTEREST OR ANY PREMIUM THEREON, OR OTHER COSTS
INCIDENT THERETO.  THE BONDS ARE PAYABLE SOLELY FROM THE REVENUES IN THE
INDENTURE PLEDGED TO SUCH PAYMENT AND NO OWNER OR OWNERS OF THE BONDS SHALL EVER
HAVE THE RIGHT TO COMPEL ANY EXERCISE OF THE TAXING POWER OF THE CITY, THE STATE
OF ILLINOIS OR ANY POLITICAL SUBDIVISION THEREOF NOR TO ENFORCE THE PAYMENT OF
THE BONDS AGAINST ANY PROPERTY OF THE CITY, THE STATE OF ILLINOIS OR ANY SUCH
POLITICAL SUBDIVISION.  THE PROJECT IS NOT SECURITY FOR THE BONDS, AND THE BONDS
ARE NOT SECURED BY 


                                      A-3
<PAGE>

ANY OTHER PROPERTY OR IMPROVEMENTS AT THE AIRPORT OR ANY REVENUES DERIVED BY 
THE CITY FROM THE OPERATION OF THE AIRPORT GENERALLY.  

    3.   INTEREST RATE.  Interest on this Bond will be paid at the lesser of
(a) a Daily Rate, a Weekly Rate, a Commercial Paper Rate or a Long-Term Interest
Rate, as selected by the Company and as determined in accordance with the
Indenture, and (b) 12 percent per annum or, when a Letter of Credit secures the
Bonds, such lower maximum rate as may be specified in the Letter of Credit. 
Interest will initially be payable at a Weekly Rate as set forth in the
Indenture.  The Company may change the interest rate determination method from
time to time.  A change in the interest rate determination method will result in
redemption of the Bonds (see "REDEMPTION" below).  While there exists an Event
of Default under the Indenture, the interest rate on the Bonds will be the
interest rate on the Bonds in effect on the day before the Event of Default
occurred.

    When interest is payable at a Daily, Weekly or Commercial Paper Rate, it
will be computed on the basis of the actual number of days elapsed over a year
of 365 days (366 in leap years), and when payable at a Long-Term Interest Rate,
it will be computed on the basis of a 360-day year of twelve 30-day months.
Interest on overdue principal and, to the extent lawful, on overdue premium and
interest will be payable at the interest rate on each Bond in effect on the day
before the default occurred.

    4.   INTEREST PAYMENT AND RECORD DATES.  Interest will accrue on the unpaid
portion of the principal of this Bond from the last date to which interest was
paid or, if no interest has been paid, from the date of the original issuance of
the Bonds until the entire principal amount of this Bond is paid.  When interest
on this Bond is payable at the rate shown in the first column below, interest
accrued during the period (an "INTEREST PERIOD") shown in the second column
below will be paid on the date (an "INTEREST PAYMENT DATE") shown in the third
column below to the Registered Owner on the date (a "RECORD DATE") shown in the
fourth column below:

    Period, or if there shall be an early termination of such Long-Term
    Interest Rate Period and a new Long-Term Interest Rate shall be set, such
    Long-Term Interest Rate Period 


                                      A-5

"BUSINESS DAY" is defined in the Indenture.  Any interest on this Bond which is
payable, but is not punctually paid or duly provided for on any Interest Payment
Date, will forthwith cease to be payable to the Registered Owner on the relevant
Record Date and will be paid to the Registered Owner on the fifth Business Day
preceding the date of payment of such defaulted interest.

    5.   METHOD OF PAYMENT.  Owners must surrender Bonds to the Trustee to
collect principal at maturity or upon redemption.  See "Tenders" below for the
method of collecting the payment of the purchase price of tendered Bonds. 
Interest on Bonds bearing interest at a Commercial Paper Rate is payable only
upon presentation of such Bonds to the Trustee.  Interest on Bonds bearing
interest at a Daily Rate, Weekly Rate or Long-Term Interest Rate will be paid to
the Registered Owner as of each Record Date by check mailed by first-class mail
on the Interest Payment Date to such Registered Owner's registered address.  A
Registered Owner of $1,000,000 or more in aggregate principal amount of Bonds
may be paid interest at a Daily Rate, Weekly Rate or Commercial Paper Rate by
wire transfer to an account in the continental United States if such Registered
Owner makes written request to the Trustee (in form satisfactory to the Trustee)
at least two Business Days before the Record Date specifying the account number
and address.  The notice may provide that it will remain in effect for all later
interest payments until changed or revoked by another written notice. 
Principal, premium, if any, and interest will be paid in money of the United
States that at the time of payment is legal tender for 
- ------------------------------------------------------------------------------
    shall end on the day immediately preceding the date on which the new 
    interest rate shall become effective, which date shall be the Interest 
    Payment Date for such Long-Term Interest Rate Period, for which the Record
    Date shall be 15 days prior to such Interest Payment Date or, if sooner, 
    the first day of such Long-Term Interest Rate Period.  If such new interest
    rate shall be a Daily Rate or a Weekly Rate, the first Interest Period 
    relating thereto shall begin on the effective date of such new interest 
    rate and end on the day prior to the first Business Day of the next 
    succeeding calendar month, for which the Interest Payment Date and the
    Record Date shall be prescribed in this Table.

*** If an Interest Payment Date occurs less than 15 days after the first day of
    a Long-Term Interest Rate Period, the first day of such Long-Term Interest
    Rate Period is the Record Date for such Interest Payment Date.

payment of public and private debts.  If any payment on the Bonds is due on a 
non-Business Day, it will be made on the next Business Day, and no interest 
will accrue as a result of such later payment.

    6.   TENDERS.  "TENDER" means to require, or the act of requiring, the
Trustee to purchase a Bond at its Owner's option under the provisions of this
Section 6 at 100 percent of the principal amount thereof plus accrued interest,
if any, to the date of purchase.  

         DAILY RATE TENDER.  When interest on the Bonds is payable at a Daily
    Rate and the Book-Entry System is in effect, a Beneficial Owner of a Bond
    may tender such Bond (or any portion thereof in an authorized denomination)
    by delivering an irrevocable written notice or an irrevocable telephone
    notice, promptly confirmed in writing, to the Remarketing Agent by 11:00
    a.m., New York City time, on any Business Day, stating the principal amount
    of the Bond (or portion thereof) being tendered, the name, address and
    taxpayer identification number of such Beneficial Owner, payment
    instructions for the purchase price and the Business Day (which may be the
    date the notice is delivered) on which such Bond (or portion thereof) is to
    be purchased.

         When interest on the Bonds is payable at a Daily Rate and the 
    Book-Entry System is not in effect, an Owner of a Bond may tender such 
    Bond (or any portion thereof in an authorized denomination) by delivering
    a notice as described above (which shall include the certificate number of 
    such Bond), and shall also deliver such Bond to the Remarketing Agent by 
    1:00 p.m., New York City time, on the date of purchase (see Section 7).

         WEEKLY RATE TENDER.  When interest on the Bonds is payable at a Weekly
    Rate and the Book-Entry System is in effect, a Beneficial Owner of a Bond
    may tender such Bond (or any portion thereof in an authorized denomination)
    by delivering an irrevocable written notice or an irrevocable telephone
    notice, promptly confirmed in writing, to the Remarketing Agent on any
    Business Day, stating the principal amount of the Bond (or portion thereof)
    being tendered, the name, address and taxpayer identification number of
    such Beneficial Owner, 


                                      A-7
<PAGE>

    payment instructions for the purchase price and the date (which must be a
    Business Day at least seven days after the notice is delivered) on which
    such Bond (or portion thereof) is to be purchased.

         When interest on the Bonds is payable at a Weekly Rate and the 
    Book-Entry System is not in effect, an Owner of a Bond may tender such Bond
    (or any portion thereof in an authorized denomination) by delivering a 
    notice as described above (which shall include the certificate number of 
    such Bond), and shall also deliver such Bond to the Remarketing Agent by 
    10:00 a.m., New York City time, on the date of purchase (see Section 7).

    PAYMENT OF PURCHASE PRICE.  The purchase price for a tendered Bond will be
paid in immediately available funds to the Owner of the Bond by the close of
business on the date of purchase.

    7.   DELIVERY ADDRESS; ADDITIONAL DELIVERY REQUIREMENTS.  Notices in
respect of tenders and Bonds tendered must be delivered to the Remarketing Agent
as follows:

    The First National Bank of Chicago 
    One First National Plaza, Suite 0463
    Chicago, Illinois 60670-0463
    Attention:  Municipal Department
    Telephone:  (312) 732-9274
    Fax:  (312) 732-8733

The address of the Remarketing Agent may be changed by notice mailed by 
first-class mail to the Bondholders at their registered addresses.

    All tendered Bonds must be duly endorsed for transfer or accompanied by an
instrument of transfer satisfactory to the Remarketing Agent and the Trustee
duly executed in blank by the Owner or his duly authorized attorney, with the
signature guaranteed by a bank, trust company or member firm of the New York
Stock Exchange, Inc.

    LIMITATION ON TENDERS.  No Bonds may be tendered while they bear interest
at a Commercial Paper Rate or a Long-Term Interest Rate or during 


                                      A-8
<PAGE>

the existence of an Event of Default under Section 8.01(h) or (i) of the 
Indenture which has led to an acceleration of the Bonds.

    IRREVOCABLE NOTICE DEEMED TO BE TENDER OF BOND; UNDELIVERED BONDS.  The
giving of any notice of tender by a Beneficial Owner of a Bond as provided in
Section 6 constitutes the irrevocable tender for purchase of each Bond with
respect to which such notice was given, irrespective of whether such Bond is
delivered as provided in Section 6.  The determination of the Remarketing Agent
as to whether a notice of tender has been properly delivered shall be conclusive
and binding upon such Beneficial Owner.  Any notice received by the Remarketing
Agent from any person reasonably believed by the Remarketing Agent to be the
Beneficial Owner of a Bond may be conclusively relied upon by the Remarketing
Agent as an effective irrevocable notice of tender for such Bond.

    The Remarketing Agent may refuse to accept delivery of any Bond not duly
endorsed for transfer or for which a proper instrument of transfer has not been
provided.  If any Beneficial Owner of a Bond who gives notice of tender fails to
deliver such Bond to the Remarketing Agent at the place and on the applicable
date and time specified, or fails to deliver such Bond properly endorsed or with
a proper instrument of transfer, such Bond shall constitute an Undelivered Bond
as described in the Indenture.  BY ACCEPTANCE OF THIS BOND, THE OWNER AGREES TO
SELL AND SURRENDER THIS BOND, PROPERLY ENDORSED OR WITH A PROPER INSTRUMENT OF
TRANSFER, TO THE REMARKETING AGENT AFTER THE GIVING OF IRREVOCABLE NOTICE OF
TENDER FOR PURCHASE AS DESCRIBED ABOVE.

    8.   REDEMPTIONS.  As provided below, the Company has the right to purchase
Bonds in lieu of certain redemptions.  BY ACCEPTANCE OF THIS BOND, THE OWNER
AGREES TO SELL AND SURRENDER THIS BOND, PROPERLY ENDORSED OR WITH A PROPER
INSTRUMENT OF TRANSFER, TO THE COMPANY IN LIEU OF REDEMPTION UNDER THE
CONDITIONS DESCRIBED BELOW.  All redemptions and purchases in lieu of redemption
will be paid in funds immediately available on the redemption or purchase date
at a redemption or purchase price of 100 percent of the principal amount of the
Bonds being redeemed or purchased (plus any premium required as provided below),
plus accrued interest, if any, to the relevant 


                                      A-9
<PAGE>

redemption or purchase date; PROVIDED, HOWEVER, that installments of interest 
which shall have become due and payable on or prior to such redemption or 
purchase date shall be payable to the Owners of the Bonds being redeemed or 
purchased (or any predecessor Bonds) at the close of business on the relevant 
Record Date.  Bonds tendered for purchase on a date after a call for 
redemption but before the redemption date will be purchased pursuant to the 
tender.  No purchase of Bonds by or on behalf of the Company shall be deemed 
to be a payment or redemption of such Bonds or of any portion thereof, and 
such purchase will not operate to extinguish or discharge the indebtedness 
evidenced by such Bonds.

    OPTIONAL REDEMPTION DURING DAILY OR WEEKLY RATE PERIOD.  When interest on
the Bonds is payable at a Daily Rate or Weekly Rate, the Bonds may be redeemed,
without premium, at the option of the Company, in whole or in part, on any
Business Day.

    OPTIONAL REDEMPTION DURING LONG-TERM INTEREST RATE PERIOD.  During any
Long-Term Interest Rate Period, the Bonds may be redeemed at the option of the
Company, in whole at any time or in part from time to time, as follows:

         (a)  until interest on the Bonds shall have been payable at the same
    Long-Term Interest Rate for more than 10 consecutive years, the Bonds will
    not be redeemable pursuant to this option; and

         (b)  after the elapse of such 10-year period, the Bonds may be
    redeemed at the redemption price specified in the introductory paragraph of
    this Section 8, plus a premium of two percent of the principal amount
    thereof during the first year after such 10-year period, a premium of one
    percent of the principal amount thereof during the second year after such
    10-year period and thereafter without premium.

    Upon receipt by the Trustee of a Favorable Opinion of Tax Counsel, the
redemption periods and prices required by the preceding paragraph may be changed
by the Remarketing Agent (with the written consent of the Company) with respect
to any Long-Term Interest Rate Period prior to the establishment thereof.  In
order to effectuate such a change, the 


                                      A-10
<PAGE>

Remarketing Agent will determine and certify to the Trustee, on a date which 
is no later than the date of establishment of the related Long-Term Interest 
Rate, the period during which the Bonds will not be subject to redemption 
(the "CALL PROTECTION PERIOD"), the redemption premium or premiums (the "CALL 
PREMIUMS"), if any, applicable to the redemption of the Bonds after the Call 
Protection Period and the period or periods during which the Call Premiums 
shall be effective (the "CALL PREMIUM PERIODS") necessary to establish such 
Long-Term Interest Rate.  Such Call Protection Period, Call Premiums and Call 
Premium Periods shall be established in accordance with optional call 
redemption provisions which the Remarketing Agent certifies, and demonstrates 
to the satisfaction of the Trustee and the Company, are generally accepted as 
the standard features for obligations such as the Bonds, based on the 
duration of such Long-Term Interest Rate Period.  

    EXTRAORDINARY OPTIONAL REDEMPTION.  The Bonds may be redeemed, without
premium, at the option of the Company, in whole at any time within 180 days of
the occurrence of any of the following:

         (a)  all or substantially all of the Project shall be damaged or
    destroyed and the Company shall determine that it is not practicable or
    desirable to rebuild, repair and restore the Project; or

         (b)  all or substantially all of the Project shall be condemned or
    such use or control thereof shall be taken by eminent domain as to render
    the Project unsatisfactory to the Company for continued operation; or

         (c)  unreasonable burdens or excessive liabilities shall be imposed
    upon the City or the Company with respect to the Project or the operation
    thereof; or

         (d)  as a result of any changes in the Constitution of Illinois or in
    the Constitution of the United States of America or of legislative or
    administrative action (whether state or federal), or by final decree,
    judgment or order of any court or administrative body (whether state or
    federal) entered after the contest thereof by the Company in good faith,
    the Loan Agreement shall have become impossible of 


                                      A-11
<PAGE>

    performance in accordance with the intent and purposes of the parties as
    expressed in the Loan Agreement.

    MANDATORY REDEMPTION ON DETERMINATION OF TAXABILITY.  The Bonds will be
redeemed or purchased by the Company in lieu of redemption, without premium, in
whole (or in part as provided below) on any day within 120 days after the
Company receives written notice from a Beneficial Owner or former Beneficial
Owner or the Trustee of a final determination by the Internal Revenue Service or
a court of competent jurisdiction that, as a result of a failure by the Company
to perform any of its agreements in the Loan Agreement or the Tax Agreement or
the inaccuracy of any of its representations in the Loan Agreement or the Tax
Agreement, the interest paid or to be paid on any Bond (except to a "substantial
user" of the Project or a "related person" within the meaning of Section 147(a)
of the Code) is or will be includible in the gross income of the Beneficial
Owner thereof for federal income tax purposes.  No such determination will be
considered final unless the Beneficial Owner or former Beneficial Owner involved
in the determination gives the Company and the Trustee prompt written notice of
the commencement of the proceedings resulting in such determination and offers
the Company, subject to the Company's agreeing to pay all reasonable expenses of
the proceedings and to indemnify such Beneficial Owner or former Beneficial
Owner against all liabilities that might result from it, the opportunity to
control the defense of the proceedings and either the Company does not agree
within 30 days to pay such reasonable expenses, to so indemnify and to control
the defense or the Company exhausts or chooses not to exhaust available
procedures to contest or obtain review of the result of the proceedings.  Fewer
than all the Bonds may be redeemed if redemption of fewer than all would result
in the interest payable on the Bonds remaining Outstanding being not includible
in the gross income for federal income tax purposes of any Beneficial Owner
other than a "substantial user" or "related person."  If fewer than all Bonds
are redeemed, the Trustee will select the Bonds to be redeemed as provided in
the Indenture and as may be specified in an Opinion of Tax Counsel.

    MANDATORY REDEMPTION UPON A CHANGE IN THE METHOD OF DETERMINING THE 
INTEREST RATE ON THE BONDS.  On the effective date of any change in the 
method of determining the interest rate on the Bonds, the Bonds will be 
redeemed or purchased by the Company in lieu of redemption, without 


                                      A-12
<PAGE>

premium, on the effective date of such change, but if interest on the Bonds 
is payable at a Long-Term Interest Rate and if such effective date is before 
the day after the last day of the then current Long-Term Interest Rate 
Period, the Bonds will be redeemed or purchased at the redemption or purchase 
price specified in the introductory paragraph of this Section 8, plus such 
premium as would be payable at such time upon a redemption described under 
"OPTIONAL REDEMPTION DURING LONG-TERM INTEREST RATE PERIOD" above.

    MANDATORY REDEMPTION UPON EXPIRATION OF LETTER OF CREDIT.  The Bonds will 
be redeemed or purchased by the Company in lieu of redemption on the Interest 
Payment Date next preceding the Expiration Date of the Letter of Credit 
unless the Trustee has received notice that the Letter of Credit has been or 
will be extended as provided in the Indenture.  When the Bonds bear interest 
at a Long-Term Interest Rate, the Bonds will be redeemed or purchased at the 
percentage of their principal amount which would be payable upon a redemption 
described under the paragraph "OPTIONAL REDEMPTION DURING LONG-TERM INTEREST 
RATE PERIOD" above. If Bonds are to be redeemed under another paragraph of 
this Section on the same day, the Bonds will be called under, and redemption 
will be governed by, the other paragraph and not by this paragraph, except 
that any premium required by this paragraph shall be paid upon such 
redemption.

    MANDATORY REDEMPTION UPON DELIVERY OF AN ALTERNATE LETTER OF CREDIT.  The 
Bonds will be redeemed or purchased by the Company in lieu of redemption on 
the Interest Payment Date next preceding the effective date of any Alternate 
Letter of Credit delivered to the Trustee.  When the Bonds bear interest at a 
Long-Term Interest Rate, the Bonds will be redeemed or purchased at the 
percentage of their principal amount which would be payable upon a redemption 
described under the paragraph "OPTIONAL REDEMPTION DURING LONG-TERM INTEREST 
RATE PERIOD" above. If Bonds are to be redeemed under another paragraph of 
this Section on the same day, the Bonds will be called under, and redemption 
will be governed by, the other paragraph and not by this paragraph, except 
that any premium required by this paragraph shall be paid upon such 
redemption.

    MANDATORY REDEMPTION AT BEGINNING OF A NEW LONG-TERM INTEREST RATE PERIOD. 
When the Bonds bear interest at a Long-Term Interest Rate 


                                      A-13
<PAGE>

and a new Long-Term Interest Rate Period is to be determined, the Bonds will 
be redeemed or purchased by the Company in lieu of redemption, without 
premium, on the first day of the new Long-Term Interest Rate Period.  If such 
first day is before the day after the last day of the then current Long-Term 
Interest Rate Period, the Bonds will be redeemed or purchased at the 
redemption or purchase price specified in the introductory paragraph of this 
Section 8, plus such premium as would be payable at such time upon a 
redemption described under "OPTIONAL REDEMPTION DURING LONG-TERM INTEREST 
RATE PERIOD" above.

    MANDATORY REDEMPTION ON EACH INTEREST PAYMENT DATE DURING COMMERCIAL PAPER
MODE.  When the Bonds bear interest at a Commercial Paper Rate, each Bond will
be redeemed or purchased by the Company in lieu of redemption, without premium,
on the Interest Payment Date of such Bond.  If the Bonds are also required to be
redeemed under the paragraph "MANDATORY REDEMPTION UPON A CHANGE IN THE METHOD
OF DETERMINING THE INTEREST RATE ON THE BONDS" above, the Bonds will be called
under, and the redemption will be governed by, that paragraph and not this
paragraph.  

    MANDATORY REDEMPTION UPON TERMINATION OF THE GROUND LEASE.  The Bonds will
be redeemed as a whole, without premium, on the effective date of any
termination of the Ground Lease. 

    MANDATORY REDEMPTION DURING A LONG-TERM INTEREST RATE PERIOD UPON EXTENSION
OF BOND MATURITY.  When the Bonds bear interest at a Long-Term Interest Rate,
the Bonds will be redeemed or purchased by the Company in lieu of redemption at
the percentage of their principal amount which would be payable upon a
redemption described under the paragraph "OPTIONAL REDEMPTION DURING LONG-TERM
INTEREST RATE PERIOD" above, on the effective date of the extension of the
maturity of the Bonds pursuant to the Company's exercise of its option under
Section 7.4(a) of the Loan Agreement.  

    MANDATORY REDEMPTION UPON EXTENSION OF BOND MATURITY.  The Bonds will be
redeemed or purchased by the Company in lieu of redemption, without premium, on
the effective date of the extension of the maturity of the Bonds pursuant to the
Company's exercise of its option under Section 7.4(b) of the Loan Agreement.


                                      A-14
<PAGE>

    MANDATORY REDEMPTION AT THE DIRECTION OF THE BANK.  The Bonds will be
redeemed or purchased by the Company in lieu of redemption, without premium, on
a Business Day specified by the Bank (which Business Day must be no more than
four days after the receipt by the Trustee of such notice) if the Bank has
delivered to the Trustee a written notice (a) that an event of default under the
reimbursement agreement pursuant to which the Letter of Credit was issued has
occurred and (b) directing the Trustee to call all Bonds for redemption pursuant
to this paragraph.  

    NOTICE OF REDEMPTION.  The Trustee will mail a notice of redemption by
first-class mail to each Bondholder at its registered address at least 30 days
before each redemption of the Bonds except for (a) a redemption described in
"MANDATORY REDEMPTION ON EACH INTEREST PAYMENT DATE DURING COMMERCIAL PAPER
MODE" as described above, for which no notice will be given; (b) redemptions as
described in "MANDATORY REDEMPTION UPON A CHANGE IN THE METHOD OF DETERMINING
THE INTEREST RATE ON THE BONDS" or "MANDATORY REDEMPTION AT BEGINNING OF A NEW
LONG-TERM INTEREST RATE PERIOD," for which notice of redemption will be given at
least 15 days before the redemption date if a Long-Term Interest Period is not
then in effect; PROVIDED, HOWEVER, that when the Book-Entry System is not in
effect, such notice will be mailed not more than five Business Days after
receipt by the Trustee of the Company's notice of a change in the method of
determining the interest rate on the Bonds which will result in a "MANDATORY
REDEMPTION UPON A CHANGE IN THE METHOD OF DETERMINING THE INTEREST RATE ON THE
BONDS" as described above and (c) a redemption described in "MANDATORY
REDEMPTION AT THE DIRECTION OF THE BANK" shall be given at least two days prior
to the redemption date.  Failure to give any required notice of redemption as to
any particular Bonds will not affect the validity of the call for redemption of
any Bonds in respect of which no such failure has occurred.  Any notice mailed
as provided in this paragraph will be conclusively presumed to have been given,
whether or not actually received by the addressee.

    EFFECT OF NOTICE OF REDEMPTION.  When notice of redemption is required and
duly given, or when Bonds are to be redeemed without notice, all Bonds called
for redemption will become due and payable on the redemption date at the
applicable redemption price, subject to the Company's right to purchase such
Bonds in lieu of redemption as provided 


                                      A-15
<PAGE>

above; in any such case, when funds are deposited with the Trustee sufficient 
for such redemption or for such purchase, interest on the Bonds to be so 
redeemed or purchased will cease to accrue as of the date of such redemption 
or purchase.

    9.   EXTENSION OF MATURITY OF THE BONDS.  The maturity of the Bonds may be
extended at the option of the Company as provided in Section 7.4 of the Loan
Agreement.  Upon compliance with all conditions to such extension contained in
Section 7.4 of the Loan Agreement, on the effective date the maturity date of
the Bonds shall for all purposes be extended to the date specified in the
Company's notice exercising such option.

    10.  LETTER OF CREDIT.  The Bonds are initially secured by a letter of
credit issued by The First National Bank of Chicago in favor of the Trustee. 
This letter of credit entitles the Trustee to draw an amount sufficient to pay
the principal of the Bonds, plus an amount equal to 45 days' interest accrued on
the Bonds at a maximum rate of 12 percent.  It expires September 23, 2002, or on
the earlier occurrence of events specified in it.  On its expiration, unless the
Company has provided another credit facility meeting the requirements of the
Indenture, the Bonds will be redeemed or purchased by the Company in lieu of
redemption (see "REDEMPTION" above).

    11.  DENOMINATIONS; TRANSFER; EXCHANGE.  The Bonds are issuable in
registered form without coupons in denominations as follows:  (1) when interest
is payable at a Long-Term Interest Rate, $5,000 and integral multiples of $5,000
up to $100,000 and integral multiples of $100,000 thereafter; and (2) when
interest is payable at a Daily Rate, Weekly Rate or Commercial Paper Rate,
$100,000 or any integral multiple of $100,000.  An Owner may transfer or
exchange Bonds in accordance with the Indenture.  The Trustee may require an
Owner, among other things, to furnish appropriate endorsements and transfer
documents and to pay any taxes and fees required by law or permitted by the
Indenture.  Except in connection with the purchase of Bonds tendered for
purchased in lieu of redemption, the Trustee shall not be required to transfer
or exchange any Bond which has been called for redemption or during the period
beginning 15 days before the mailing of a notice calling the Bonds or any
portion of the Bonds for redemption and ending on the redemption date.


                                      A-16
<PAGE>

    12.  PERSONS DEEMED OWNERS.  The Registered Owner of this Bond will be
treated as the owner for all purposes, and all payments of principal, premium,
interest and purchase price shall be made only to or upon the written order of
the Registered Owner or the Registered Owner's legal representative.

    13.  UNCLAIMED MONEY.  If money for the payment of principal, premium, 
interest or purchase price with respect to any Bond remains unclaimed for two 
years after all outstanding Bonds have become due at maturity or through 
redemption, the Trustee will pay the money to or for the account of the 
Company. After such payment, the persons entitled to such money must look 
only to the Company (unless an abandoned property law designates another 
person) and not to the Trustee, the City, the Bank or the Remarketing Agent 
for payment.

    14.  DISCHARGE BEFORE REDEMPTION OR MATURITY.  If the Company at any time 
deposits with the Trustee moneys or U.S. Government Obligations as described 
in the Indenture sufficient to pay at maturity or on redemption the principal 
of and premium, if any, and interest on the Outstanding Bonds, and if the 
Company also pays all other sums then payable by the Company under the 
Indenture, the lien of the Indenture with respect to the Bonds will be 
discharged.  After discharge, Bondholders must look only to the deposited 
moneys and securities for payment.  U.S. Government Obligations means (i) 
noncallable direct obligations of the United States of America for which its 
full faith and credit are pledged, (ii) noncallable obligations of a person 
controlled or supervised by and acting as an agency or instrumentality of the 
United States of America, the payment of which is unconditionally guaranteed 
as a full faith and credit obligation of the United States of America, or 
(iii) securities or receipts evidencing ownership interests in obligations or 
specified portions (such as principal or interest) of obligations described 
in clause (i) or (ii).

    15.  AMENDMENT, SUPPLEMENT.  Subject to certain exceptions, the 
Indenture, the Loan Agreement and the Bonds may be amended or supplemented 
with the consent of the Owners of a majority in aggregate principal amount of 
the Bonds and any additional parity bonds then Outstanding.  Any such consent 
shall be irrevocable and shall bind any subsequent Owner of this Bond or any 
Bond delivered in substitution for 

                                      A-17
<PAGE>

this Bond.  Without the consent of any Bondholder, the City may amend or 
supplement the Indenture, the Loan Agreement and the Bonds as described in 
the Indenture, among other things, to cure any ambiguity, inconsistency or 
formal defect or omission, to provide for the issuance of additional parity 
bonds, to provide for uncertificated Bonds in addition to or in place of 
certificated Bonds, to provide for the Book-Entry System for the Bonds, to 
make any change necessary to secure from a Rating Agency a rating on these 
Bonds equal to the rating on the unsecured indebtedness of the Bank (or the 
parent company of the Bank) or to make any change that does not materially 
adversely affect the rights of any Bondholder.

    16.  DEFAULTS AND REMEDIES.  The Indenture provides that the occurrence of
certain events constitute Events of Default.  If an Event of Default has
occurred and is continuing, Bank or, with the prior consent of the Bank in
certain instances, the Trustee, or the holders of at least 25 percent in
principal amount of the Bonds and any additional parity bonds then Outstanding
may declare the principal of all the Bonds to be due and payable immediately. 
An Event of Default and its consequences (including any acceleration) may be
waived as provided in the Indenture.  Bondholders may not enforce the Indenture
or the Bonds except as provided in the Indenture.  Except as specifically
provided in the Indenture, the Trustee may refuse to enforce the Indenture or
the Bonds unless it receives indemnity satisfactory to it.  Subject to certain
limitations, Owners of a majority in aggregate principal amount of the Bonds and
any additional parity bonds then Outstanding may direct the Trustee in its
exercise of any trust or power.

         (b)  Each of this Loan Agreement, the Bonds, the Indenture and the 
    Tax Agreement has been duly authorized, executed and delivered by the 
    City and each constitutes the legal, valid and binding obligation of the

    the extent that the enforcement thereof may be limited by laws relating 
    to bankruptcy, insolvency, reorganization, moratorium or other similar 
    laws and equitable principles of general application affecting the rights 
    and remedies of creditors and secured parties.

         (c)  So long as any of the Bonds remain outstanding and except as 
    may be authorized by the Indenture, the City will not issue or sell any 
    bonds or obligations, other than the Bonds or Additional Bonds, the 
    principal of or interest on which will be payable from the property 
    described in the granting clause of the Indenture.

    Formation, as amended, the Ground Lease, or any indenture, mortgage deed 
    of trust, loan agreement or other agreement or instrument to which the 
    Company is bound or to which any of the property or assets of the Company 
    is subject, which would cause a material adverse change in the financial 
    position or results of operations of the Company or affect the validity 
    of this Loan Agreement, the Reimbursement Agreement, the Tax Agreement or 
    the Ground Lease or the legal authority of the Company to comply with the 
    terms thereof or hereof; nor will such action result in a violation of 
    any statute or any rule or regulation of any court or governmental agency 
    or other body in the United States having jurisdiction over the Company 
    or any of its properties which would cause a material adverse change in 
    the financial position or results of operations of the Company or affect

    comply with the terms thereof or hereof.

         (c)  This Loan Agreement, the Reimbursement Agreement, the Ground 
    Lease Amendment, the Tax Agreement and the assumption of the Ground Lease 
    by the Company have each been duly authorized, executed and delivered by 
    the Company and each constitutes the legal, valid and binding obligation 
    of the Company enforceable against the Company in accordance with its 
    terms, except to the extent that the enforcement thereof may be limited 
    by laws relating to bankruptcy, insolvency, reorganization, moratorium or 
    other similar laws and equitable principles of general application 
    affecting the rights and remedies of creditors and secured parties.

         (d)  There is no litigation or proceeding pending, or to the 
    knowledge of the Company after due inquiry threatened, against the

                                   -4-

<PAGE>

    Company, or affecting it, which could adversely affect the validity of this
    Loan Agreement, the Ground Lease Amendment, the Tax Agreement or the 
    ability of the Company to comply with its obligations under either such 
    document.

         (e)  The information contained in the Tax Agreement and the Project 
    Certificate is, and  at the time of issuance of the Bonds will be, true 
    and correct in all material respects.

         (f)  The Project consists and will consist of the facilities 
    described in Exhibit A, and no changes shall be made in the Project 
    except as permitted by Section 3.2.

                    COMPLETION AND OPERATION OF PROJECT

    SECTION 3.1.   CONSTRUCTION OF PROJECT.  The Company will complete the 
construction, installation and equipping of the Project as soon as 
practicable in accordance with the plans and specifications kept, and as they 
may be revised, under the following Section.  The City does not represent 
that the proceeds of the Bonds will be sufficient to pay the costs of 
completing the Project.  If the proceeds from the Bonds are not sufficient 
for completion of the Project, the Company will complete the Project with its 
own funds and will not thereby be entitled to reimbursement of any amount 
from the City, the Trustee or any Bondholder or to any reduction of any 
amounts payable by the Company hereunder.

    SECTION 3.2.   PLANS AND SPECIFICATIONS.  Subject to the provisions of 
the next paragraph and to any applicable provisions of the Ground Lease, the 
Company may make, authorize or permit changes or amendments in the components 
of the Project or may determine not to complete any portion of the Project 
for which Bond proceeds (and investment income thereon) are available, or may 
finance such portion of the Project from any other source;

                                   -5-

<PAGE>

PROVIDED, HOWEVER, that Bond proceeds (and investment income) otherwise 
allocable to such portion of the Project must be used either (i) to pay costs 
of the remaining parts of the Project, (ii) to pay the cost of other air 
cargo facilities as approved by an Opinion of Tax Counsel, subject to the 
provisions of the next paragraph or (iii) to pay or redeem principal on the 
Bonds in accordance with the provisions of this Loan Agreement and the 
Indenture, PROVIDED that in the case of (ii) or (iii), the Company shall have 
received a Favorable Opinion of Tax Counsel with respect to such application. 
If the Company determines not to complete any portion of the Project or to 
fund such portion from any other source, such portion of the Project shall no 
longer be deemed to be within the meaning of the term "Project" for any 
purpose of this Loan Agreement or the Indenture.

    No change or amendment in the components of the Project pursuant to the 
terms of the preceding paragraph shall be made if such change or amendment 
causes the economic life of the Project to be reduced unless the Company 
shall have delivered to the Trustee a Favorable Opinion of Tax Counsel with 
respect to such change or amendment. A copy of each such change in or 
amendment to EXHIBIT A hereof shall be filed promptly with the City and the 
Trustee.  In addition, the Company shall deliver to the Trustee a certificate 
of a Company Representative detailing the proposed changes.

    SECTION 3.3.   RECORDS.  The Company will maintain such records in 
connection with the Project as are required to permit ready identification of 
the Project and items of Project Costs.

    SECTION 3.4.   OPERATION OF PROJECT.  The Company will operate the 
Project, or cause the Project to be operated, as airport facilities as 
contemplated by Section 142(a)(1) of the Code and as Airport Support Services 
within the meaning of such term in the Ground Lease.

    SECTION 3.5.   RIGHT OF ACCESS TO THE PROJECT AND INSPECTION OF RECORDS.  
The Company agrees that during the term of this Loan Agreement the City, the 
Trustee and the duly authorized agents of either of them shall have the right 
(but not any duty or obligation) at all reasonable times upon reasonable 
notice to the Company during normal business hours to inspect the records 
maintained by the Company pursuant to Section 3.3 and to enter upon the site 
of the Project to examine and inspect the Project; PROVIDED, HOWEVER, that 
this right is subject to federal and State laws and regulations

                                   -6-

<PAGE>

applicable to the Project Site.  The rights of inspection and access hereby 
reserved to the City and the Trustee may be exercised only after such agent 
shall have executed release of liability and secrecy agreements if requested 
by the Company in the form then currently used by the Company, and nothing 
contained in this Section or in any other provision of this Loan Agreement 
shall be construed to entitle the City or the Trustee to any information or 
inspection involving the confidential know-how of the Company.  
Notwithstanding the foregoing, the City shall have all rights of access and 
inspection to the Project as are set forth in the Ground Lease.

    SECTION 3.6.   COMPANY REPRESENTATIVE.  The Company has appointed the 
Company Representative for the purpose of acting on behalf of the Company and 
taking all actions and making all certificates required to be taken and made 
by a Company Representative under the provisions of this Loan Agreement and 
the Indenture.  The Company may appoint alternative Company Representatives 
to take any such action or make any such certificate if the same is not taken 
or made by the Company Representative.  In the event any of said persons, or 
any successor appointed pursuant to the provisions of this Section, should 
resign or become unavailable or unable to take any action or make any 
certificate provided for in this Loan Agreement or the Indenture, another 
Company Representative or alternate Company Representative shall thereupon be 
appointed by the Company.  If the Company fails to make such designation 
within 10 days following the date when the then incumbent resigns or becomes 
unavailable or unable to take any of the said actions, the Treasurer of the 
Company shall serve as the Company Representative.

    Whenever under the provisions of this Loan Agreement or the Indenture the 
approval of the Company is required or the City is required to take some 
action at the request of the Company, such approval or such request shall be 
made by the Company Representative or alternate Company Representative unless 
otherwise specified in this Loan Agreement or the Indenture, and the City or 
the Trustee shall be authorized to act on any such approval or request.

                                   -7-

                                ARTICLE IV

                 LOAN OF BOND PROCEEDS; PAYMENTS BY COMPANY;

                            ASSIGNMENT BY CITY


    SECTION 4.1.   THE LOAN.  The City agrees, upon the terms and conditions 
in this Loan Agreement, to lend to the Company the proceeds received by the 
City from the sale of the Bonds, in order to pay Project Costs, by depositing 
the same as provided in Section 4.01 of the Indenture.

    SECTION 4.2.   PAYMENTS BY COMPANY.  The Company agrees to pay to the 
Trustee, as assignee of the City, for so long as any Bonds are Outstanding, 
on or before each date upon which the principal of, or the premium, if any, 
or interest on, the Bonds is payable in accordance with the provisions of the 
Indenture, a sum which, together with other money available therefor under 
the Indenture, will equal the sum of the principal of, and the premium, if 
any, and interest on, the Bonds which will be payable on such date (whether 
at maturity or by redemption or otherwise in accordance with the terms of the 
Indenture).  The Company will further pay to the Trustee, on each day on 
which a payment of the purchase price of a tendered Bond shall become due and 
payable, an amount which, together with other money held by the Trustee under 
the Indenture and available therefor, will enable the Trustee to make such 
payment in full in a timely manner.  In furtherance of the foregoing, so long 
as any Bonds are Outstanding, the Company will pay or cause to be paid all 
amounts required to prevent any deficiency or default in any payment of the 
principal of, the premium, if any, and interest on, and the purchase price 
of, the Bonds, including any deficiency caused by an act or failure to act by 
the Trustee, the Company, the City, the Remarketing Agent or any other 
person.  In the event the Company should fail to make or cause to be made any 
of the payments required in this Section 4.2, the payment so in default shall 
continue as an obligation of the Company until the amount in default shall 
have been fully paid, and the Company agrees to pay the same with interest 
thereon (to the extent permitted by law) until paid at the rate or rates then 
borne by the Bonds.

    SECTION 4.3.   NO DEFENSE OR SET-OFF.  The obligation of the Company to 
make the payments required under this Loan Agreement shall be absolute and 
unconditional, without defense, recoupment or set-off by

                                   -8-

<PAGE>

reason of any default by the City under this Loan Agreement, the Ground Lease 
or under any other agreement between the Company and the City or for any 
other reason, including, without limitation, any acts or circumstances that 
might constitute failure of consideration, destruction of or damage to the 
Project, condemnation or failure of title of the Project or the Project Site, 
commercial frustration of purpose or failure of the City to perform and 
observe any agreement, whether express or implied, or any duty, liability or 
obligation to the Company, whether arising out of or connected with this Loan 
Agreement, it being the intention of the parties that the payments required 
by this Loan Agreement will be paid in full when due without any delay or 
diminution whatsoever.

    SECTION 4.4.   ASSIGNMENT OF CITY'S RIGHTS.  As security for the payment 
of the Bonds, the City will upon the issuance of the Bonds pledge and assign 
to the Trustee the City's rights under this Loan Agreement (except the right 
to receive payments, if any, under Sections 5.1, 5.3, 6.2 and 8.4).  The City 
directs the Company, and the Company agrees, to pay to the Trustee at its 
principal corporate trust office all payments due and payable to the Trustee 
hereunder.  The Company will make payments directly to the Trustee without 
defense or set-off by reason of any dispute between the Company and the 
Trustee or the City.  The City and the Company hereby agree that the Trustee 
as assignee may enforce any and all rights and remedies hereunder, but the 
City retains the right to proceed in its own name against the Company for the 
enforcement or the specific performance of any obligation of the Company 
under Sections 5.1, 5.3, 6.2 and 8.4.

    SECTION 4.5.   ADDITIONAL BONDS.  Subject to approval of the City 
Council, Additional Bonds may be authorized by the City upon the request of 
the Company for the purpose of (i) completing the Project, (ii) financing the 
cost of expansion to or improvements of the Project which the Company may 
deem necessary or desirable, (iii) funding the cost of the Company's exercise 
of its option to extend the term of the Ground Lease pursuant to Section 1(b) 
of the Ground Lease Amendment, or (iv) refunding the Bonds.  Additional Bonds 
may be issued if the Company and the City enter into an amendment to this 
Loan Agreement to describe any additional properties not described in Exhibit 
A hereto with respect to (ii) above, and to provide for such increase in the 
loan payments to be paid by the Company to the City as shall be sufficient to 
pay the principal of, premium, if any, and

                                   -9-

<PAGE>

interest on the Additional Bonds. The City will deposit the proceeds from the 
sale of Additional Bonds with the Trustee as may be provided in the 
supplemental indenture pertaining to such Additional Bonds.

                                ARTICLE V

                       COVENANTS OF THE COMPANY


    SECTION 5.1.   TRUSTEE AND CITY EXPENSES.  (a) The Company agrees that 
there shall be paid to the City as an administrative fee on the date of 
issuance of the Bonds an amount equal to one-quarter of one percent of the 
principal amount of the Bonds.  Such amount shall be paid from Bond proceeds 
from the Costs of Issuance Fund; 

         (b)  the Company agrees to pay to the Trustee until the principal of,
    and the premium, if any, and interest on, all Outstanding Bonds shall have
    been fully paid:

              (i)  an amount, as previously agreed upon in writing between 
         the Company and the Trustee, equal to the annual fee of the Trustee 
         for its ordinary services, plus its ordinary expenses, as and when 
         the same become due;

             (ii) the reasonable fees, charges and expenses of the Trustee for
         its necessary extraordinary services, as and when the same become due;
         and

            (iii) the cost of registering and transferring any Bonds under the
         provisions of the Indenture.

    The Company will pay all reasonable expenses of the City incurred in 
connection with this Loan Agreement and the Indenture or arising out of the 
issuance of the Bonds, including the fees of Rudnick & Wolfe, special counsel 
to the City.

    SECTION 5.2.   NO LIABILITY OF CITY.  The Bonds, together with premium, 
if any, and interest thereon, shall be limited obligations of the City giving 
rise to no pecuniary liability of the City nor a charge against its general 
credit or taxing powers and shall be payable by the City solely out of the 
amounts payable by the Company pursuant to Section 4.2 of this Loan 
Agreement.  No Owner or Beneficial Owner of any Bond shall have

                                   -10-

<PAGE>

the right to compel any exercise of the taxing power of the City or the State 
or any political subdivision thereof to pay the Bonds, the interest or 
premium, if any, thereon and the Bonds shall not constitute an indebtedness 
of the City or the State or any political subdivision thereof or a loan of 
credit thereof within the meaning of any constitutional or statutory 
provision or limitation of indebtedness applicable to the City.  No moneys 
payable by the Company to the City under the Ground Lease are assigned 
hereunder.  Neither the Trustee, the Owners nor the Beneficial Owners shall 
have any interest in the Ground Lease or any amounts payable thereunder.  The 
Bonds are not secured by the Project, nor are the Bonds secured by any 
property or improvements at the Airport or any revenues derived by the City 
from the operation of the Airport generally.  

    SECTION 5.3.   INDEMNIFICATION.  The Company will pay, and will protect, 
indemnify and save the City harmless from and against any and all 
liabilities, losses, damages, costs and expenses (including attorneys fees 
and expenses of the Company and the City), causes of action, suits, claims, 
demands and judgments of whatsoever kind and nature (including those arising 
or resulting from any injury to or death of any person or damage to Project) 
arising out of the following except when caused by the City's gross 
negligence or willful misconduct as determined by final judicial proceedings:

         (a)  the financing, design, construction and installation of the
    Project;

         (b)  the use by the Company of the Project;

         (c)  violation by the Company of any agreement, warranty, covenant or
    condition of this Loan Agreement;

         (d)  violation by the Company of any other contract, agreement or
    restriction relating to the Project; 

         (e)  violation by the Company of any law, ordinance, regulation or
    court order applicable to the Project or the ownership, occupancy or use
    thereof.

         (f)  compliance by the Company with Sections 5.4 and 5.5 hereof and 
    compliance by the City with Section 6.04 of the Indenture

                                   -11-

<PAGE>

    or any tax or project certificate delivered in connection with issuance 
    the of Bonds (including in each case, but not limited to, the use of 
    insurance or condemnation proceeds in a manner different from that set 
    forth in the Ground Lease or any restriction or limitation imposed on the 
    use of the "Project" or the "Premises" as defined in the Ground Lease or 
    any portion thereof following any termination, in whole or in part of the 
    Ground Lease).  

    The City shall promptly notify the Company in writing of any claim or 
action brought against the City in respect of which indemnity may be sought 
against the Company, setting forth the particulars of such claim or action, 
and the Company will assume the defense thereof, including the employment 
counsel, and the payment of all expenses.  The City may employ separate 
counsel in any such action and participate in the defense thereof, but the 
fees and expenses of such counsel shall not be payable by the Company unless 
such employment has been specifically authorized by the Company or unless the 
City concludes that there may be defenses available to it that are different 
from or in addition to those available to the Company.

    So long as no Event of Default has occurred and is continuing under the 
Ground Lease or the Loan Agreement, the Company shall have the right to 
exercise its option to redeem Bonds in lieu of the City taking or refraining 
from taking an action described in the opinion of nationally recognized bond 
counsel delivered in connection with Section 6.04 of the Indenture or any tax 
or project certificate delivered in connection with the Bonds, if such 
optional redemption shall be sufficient, in the opinion of such nationally 
recognized bond counsel to cause any tax or use restriction imposed upon the 
related portion of the Project or Premises (as each are defined in the Ground 
Lease) or upon proceeds belonging to the City by reason of the Bonds to be no 
longer applicable.  

    Except as provided below, the indemnity provided for in this Section 5.3 
shall be independent of, and shall not supersede or in any way limit, any 
indemnities to which the City may be entitled under the provisions of the 
Ground Lease, the Bond Placement Agreement relating to the Bonds and any 
other agreements between the City and the Company; provide that, as regards 
clauses (b) and (d) above, in the event that and only to the extent that the 
claim or action in respect to which the indemnity may be sought

                                   -12-

<PAGE>

against the Company arises from matters independent of the issuance of the 
Bonds and which matters are directly covered by provisions relating to 
indemnification and hazardous substances in the Ground Lease, then such 
provisions in the Ground Lease shall control.

    The Company agrees to indemnify the Trustee, and to hold it harmless 
against, any loss, liability or expense incurred without negligence or bad 
faith on its part arising out of or in connection with the acceptance or 
administration of the Indenture, including the costs and expenses of 
defending itself against any claim or liability in connection with the 
exercise or performance of any of its powers or duties under the Indenture.

    SECTION 5.4.   COMPANY'S OBLIGATION WITH RESPECT TO EXCLUSION OF INTEREST 
PAID ON THE BONDS.  Notwithstanding any other provision hereof or in the 
Ground Lease, the Company covenants and agrees that it will not knowingly 
take or authorize or permit, to the extent such action is within the control 
of the Company, any action to be taken with respect to the Project, the 
proceeds of the Bonds (including investment earnings thereon) or any 
insurance, condemnation or other proceeds derived directly or indirectly in 
connection with the Project which will result in the loss of the exclusion of 
interest on the Bonds from federal gross income under Section 103 of the Code 
(except for any Bond during any period while such Bond is held by a person 
referred to in Section 147(a) of the Code and except for Bonds which may be 
remarketed as taxable Bonds as provided in the first sentence of Section 
3.08(d) of the Indenture); and the Company also will not knowingly omit to 
take any action in its power which, if omitted, would cause such result.  The 
preceding sentence shall control in case of conflict or ambiguity with any 
other provision of this Loan Agreement.  The Company covenants for the 
benefit of the Beneficial Owners to comply with all of the requirements of 
Section 6.03 of the Indenture.  

    The Company covenants and agrees to notify the Trustee and the City of 
the occurrence of any event of which the Company has notice and which event 
would require the Company to prepay the amounts due hereunder because of a 
redemption of the Bonds upon a determination of taxability.

    SECTION 5.5.   COVENANTS AND REPRESENTATIONS WITH RESPECT TO ARBITRAGE.  
The Company covenants and represents to the City and to and for the benefit 
of the Beneficial Owners that so long as any of the Bonds

                                   -13-

<PAGE>

remain Outstanding, moneys on deposit in any fund in connection with the 
Bonds, whether such moneys were derived from the proceeds of the sale of the 
Bonds or from any other sources, will not be used in a manner which will 
cause the Bonds to be "arbitrage bonds" within the meaning of Section 148 of 
the Code and any lawful regulations promulgated thereunder, as the same exist 
on this date or may from time to time hereafter be amended, supplemented or 
revised.  The Company also covenants to the City and for the benefit of the 
Beneficial Owners to comply with all of the provisions of the Tax Agreement. 
The Company reserves the right, however, to make any investment of such 
moneys permitted by State law, if, when and to the extent that said Section 
148 or regulations promulgated thereunder shall be repealed or relaxed or 
shall be held void by final judgment of a court of competent jurisdiction, 
but only upon receipt of a Favorable Opinion of Tax Counsel with respect to 
such investment.

    SECTION 5.6.   MERGER AND CONSOLIDATION.  The Company agrees that during 
the term of this Loan Agreement it will maintain its corporate existence, 
will not dissolve or otherwise dispose of all or substantially all of its 
assets and will not consolidate with or merge into another corporation, 
business entity or trust (each such corporation, business entity or trust is 
herein called a "CORPORATION") or permit one or more Corporations to 
consolidate with or merge into it unless the Company is the surviving, 
resulting or transferee Corporation, as the case may be; provided that the 
Company may, without violating the agreements contained in this Section, 
consolidate with or merge into another domestic Corporation (I.E., a 
Corporation incorporated or created and existing under the laws of the United 
States of America or any state, district or territory thereof) or permit one 
or more other domestic Corporations to consolidate with or merge into it, or 
sell or otherwise transfer to another domestic Corporation all or 
substantially all of its assets as an entirety and thereafter dissolve, 
notwithstanding that the Company is not the surviving, resulting or 
transferee Corporation, as the case may be, if the surviving, resulting or 
transferee Corporation (i) is a domestic Corporation qualified to do business 
in the State and (ii) assumes in writing all of the obligations of the 
Company under this Loan Agreement and the Tax Agreement.  Notwithstanding the 
foregoing, any such transaction shall be subject to the terms of the Ground 
Lease and shall be subject to the restrictions, prohibitions and conditions 
contained in the Ground Lease.  

                                   -14-

<PAGE>

    SECTION 5.7.   TAXES AND GOVERNMENTAL CHARGES.  The Company will promptly 
pay, as the same become due, all lawful taxes, assessments and governmental 
charges of any kind whatsoever including, without limitation, income, 
profits, property and excise taxes levied or assessed by any federal, state 
or municipal government upon the City with respect to any payments under this 
Loan Agreement.  The City agrees to give the Company prompt notice of any 
such taxes, assessments or governmental charges.

    The Company may, at its expense and in its own name and behalf, or in the 
name and behalf of the City if it is a necessary party thereto, contest in 
good faith any such taxes, assessments and governmental charges and, in the 
event of any such contest, permit the taxes, assessments or governmental 
charges so contested to remain unpaid during the period of such contest and 
any appeal therefrom, provided during such period enforcement of any such 
contested item shall be effectively stayed.  The City, at the expense of the 
Company, will cooperate fully with the Company in any such contest.

    SECTION 5.8.   AGREEMENT TO SUPPLY LETTER OF CREDIT.  The Company shall 
provide for the delivery of a Letter of Credit meeting the requirements of 
Section 5.01 of the Indenture to the Trustee upon the original issuance of 
the Bonds.

    SECTION 5.9.   GROUND LEASE AMENDMENTS.  The Company agrees that the 
provisions of Section 1 of the Ground Lease Amendment may not be amended, and 
that it will not otherwise extend the term of the Ground Lease unless, in 
each case, a Favorable Opinion of Tax Counsel is delivered to the Trustee 
with respect to such amendment or extension.

    SECTION 5.10.  NO AMENDMENT OF GROUND LEASE.  This Loan Agreement shall 
not be deemed to amend or in any way supersede or alter the Ground Lease; 
although by its terms, the provisions of Section 5.4 could, under certain 
circumstances, require acts of the Company inconsistent with the Ground 
Lease.  Nothing herein shall limit the City's exercise of any right or remedy 
under the Ground Lease in the event of a default by the Company under the 
Ground Lease.  

    SECTION 5.11.  REMARKETING AGREEMENT.  The Company agrees in the 
Remarketing Agreement to cooperate with the Remarketing Agent to

                                   -15-

<PAGE>

comply with applicable provisions of Rule 15c2-12 of the Exchange Act (the 
"RULE").  The Company hereby covenants to provide notice to the City, the 
Trustee and any institution which is subject to the Rule and which is then 
making a market in the Bonds of any material events requiring disclosure, 
pursuant to any undertaking to provide continuing information required by the 
Rule.  

                                  ARTICLE VI

                           DEFAULTS AND REMEDIES


    SECTION 6.1.   REMEDIES.  Whenever any Event of Default has occurred and 
is continuing, the Trustee may take whatever reasonable action may appear 
necessary or desirable to collect the payments then due and to become due or 
to enforce performance of any agreement of the Company in this Loan Agreement.

    In addition to such remedies, the City (on its behalf to enforce the 
Unassigned Rights and without the consent of the Trustee) or the Trustee, as 
assignee of certain rights of the City hereunder, may at any time take any 
action at law or in equity to collect any payments then due, or to enforce 
performance and observance of any obligation, agreement or covenant of the 
Company under this Loan Agreement, it being understood that the City shall 
not be obligated to exercise any such remedies.

    Any amounts collected pursuant to action taken under this Section shall 
be applied in accordance with the Indenture.

    SECTION 6.2.   CERTAIN FEES AND EXPENSES.  If an Event of Default occurs 
and the City employs attorneys or incurs other expenses for the collection of 
payments due under this Loan Agreement or for the enforcement of performance 
or observance of any obligation, agreement or covenant on the part of the 
Company contained in this Loan Agreement, the Company will on demand therefor 
reimburse the reasonable fees of such attorneys and other reasonable expenses 
so incurred.

    SECTION 6.3.   NO REMEDY EXCLUSIVE.  No remedy herein conferred upon or 
reserved to the City or the Company is intended to be exclusive of any other 
available remedy or remedies, but each and every such remedy shall be 
cumulative and shall be in addition to every other remedy given

                                   -16-

<PAGE>

under this Loan Agreement or now or hereafter existing at law or in equity or
by statute.  No delay or omission to exercise any right or power accruing upon 
any default shall impair any such right or power or shall be construed to be 
a waiver thereof, but any such right or power may be exercised from time to 
time and as often as may be deemed expedient.  In order to entitle the City 
to exercise any remedy reserved to it in this Article VI, it shall not be 
necessary to give any notice, other than such notice as may be herein 
expressly required.  Such rights and remedies as are given the City hereunder 
shall also extend to the Trustee, and the Trustee, as assignee of the City 
(except for the Unassigned Rights) and the Bondholders and the Beneficial 
Owners, subject to the provisions of the Indenture, shall be entitled to the 
benefit of all covenants and agreements contained in this Loan Agreement.

    SECTION 6.4.   WAIVER.  In the event that any agreement contained in this 
Loan Agreement shall be breached by either party and such breach shall 
thereafter be waived by the other party with the consent of the Trustee, such 
waiver shall be limited to the particular breach so waived and shall not be 
deemed to waive any other breach under this Loan Agreement.

                               ARTICLE VII


                      SPECIAL OPTIONS AND OBLIGATIONS


    SECTION 7.1.   OBLIGATION TO PREPAY.  The Company shall, under Section 
4.2, make payments on such dates and in such amounts as will enable the City 
to redeem Bonds called for redemption pursuant to the Indenture.

    SECTION 7.2.   OPTION TO PREPAY.  Whenever the Bonds are subject to 
optional redemption, the City will, but only upon the direction of the 
Company, redeem the same in accordance with such direction.  The Company 
shall, pursuant to Section 4.2, make payment on the redemption date specified 
of an amount sufficient to pay the principal of, and the premium, if any, and 
interest on, the Bonds so called for redemption.

    SECTION 7.3.   OPTION TO CHANGE MODES.  The Company shall have, and is 
hereby granted, the option to elect from time to time to change the method of

<PAGE>

    (a)  The Company shall have the option to extend the stated maturity of 
the Bonds from the initial Bond maturity of September 1, 2032 to August 1, 
2042.  This option cannot be exercised during a Long-Term Interest Rate 
Period unless the Bonds are then callable under the paragraph captioned 
"OPTIONAL REDEMPTION DURING LONG-TERM INTEREST RATE PERIOD" as set forth in 
Section 8 of the Bonds, but may be exercised in conjunction with the 
commencement of a new Long-Term Interest Rate Period.  The Company shall give 
the City and the Trustee written notice of its intent to exercise this 
option.  Such notice shall be accompanied by a Favorable Opinion of Tax 
Counsel and shall state an effective date.  The effective date of such 
extension shall be set forth in the notice and may not be earlier than 30 
days after the giving of such notice, but must be no later than the day 
before the Bonds are then scheduled to mature.  On the effective date the 
Company must deliver to the Trustee a Favorable Opinion of Tax Counsel.  If 
such opinion is received on the effective date, the maturity of the Bonds 
shall be August 1, 2042 as provided in Section 9 of the Bonds. Promptly after 
the effective date, the Trustee will mail notice to Bondholders of the 
extension of the maturity.

    (b)  The Company shall have the option to extend the maturity of the 
Bonds to the extended term of the Ground Lease as such term may be extended 
by the Company pursuant to Section 1(b) of the Ground Lease Amendment (the 
"EXTENDED GROUND LEASE TERMINATION DATE").  The Company shall give the City 
and the Trustee written notice of its intent to exercise this option no later 
than 90 days prior to the stated maturity of the Bonds (or the extended 
maturity of the Bonds if the Company has exercised the option set forth in 
(a) above). Such notice shall be accompanied by a Favorable Opinion of Tax 
Counsel (it being understood that the opinion relating to the tax exemption 
of the Bonds may be limited to interest paid on the Bonds prior to the 
effective date).  The effective date of such extension shall be the day 
before the date the Bonds are then scheduled to mature.  On the effective 
date the Company must deliver to the Trustee such Favorable Opinion of Tax 
Counsel (it being understood that the opinion relating to the tax exemption 
of the Bonds may be limited to interest paid on the Bonds prior to the 
effective date).  If such opinion is received on the effective date, the 
maturity of the Bonds shall be the Extended Ground Lease Termination Date as 
provided in Section 9 of the Bonds.  After the effective date the

                                   -18-

<PAGE>

Bonds may be remarketed as tax-exempt Bonds only under the circumstances set 
forth in Section 3.08(d) of the Indenture.  Promptly after the effective date 
the Trustee will mail notice to Bondholders of the extension of the maturity.

or the validity thereof provided that the Company shall have given the City 
written notice of any action the Company proposes to take and the City shall 
not have cured such failure within 30 days of receipt of such notice.  This 
Section does not require the Company to perform any agreement of the City.  
The Company covenants and agrees to pay the expenses of the City incurred 
under, and to use its best efforts to cause the City to perform the 
obligations of the City under, Section 6.02 of the Indenture at the expense 
of the Company.

agreed by the parties hereto that (a) the City may rely conclusively on the 
truth and accuracy of any certificate, opinion, notice or other instrument 
furnished to the City by the Trustee or the Company as to the existence of 
any fact or state of affairs required hereunder to be noticed by the City;

                           FIRST AMENDMENT TO GROUND LEASE

    This First Amendment to Ground Lease ("Amendment") is executed and entered
into as of the first day of September, 1997 by and between the City of Chicago,
a municipal corporation and home rule unit of local government organized and
existing under Article VII, Sections 1 and (6)(a), respectively, of the 1970
Constitution of the State of Illinois ("Landlord"), as landlord, and CenterPoint
O'Hare L.L.C., an Illinois limited liability company ("Tenant"), as tenant.

                                      RECITALS:

    A.   Landlord and Tenant's predecessor in interest, O'Hare Tech Center
Associates, L.P., an Illinois limited partnership ("OTCA"), entered into a
Ground Lease for Site 19/O'Hare International Airport dated August 15, 1995
("Ground Lease"), relating to certain real estate consisting of approximately 
50 acres of land defined as the "Land" and described on Exhibit A to the Ground
Lease, together with all improvements thereon, situated at O'Hare International
Airport ("Airport"), pursuant to an ordinance of the City Council of Chicago
dated June 14, 1995 (C.J.P., pp. 2480-2700).  Landlord and OTCA entered into a
Corrective and Implementing Supplement to Ground Lease dated May 8, 1996 ("First
Supplement") to reflect certain corrections to the Ground Lease dated August 15,
1995, and provide for certain easements. OTCA assigned all of its right, title
and interest in and to the Lease to Tenant by an Assignment and Assumption of
Ground Lease dated May 10, 1996, consented to in advance by Landlord in a letter
to OTCA dated April 22, 1995.  Landlord and Tenant entered into a Second
Corrective and Implementing Supplement to the Ground Lease dated October 25,
1996 to reflect additional corrections to the Ground Lease, to delete the
Phase A-1 Parcel from the Premises under the Ground Lease and confirm other
matters relating to the creation of the Separate Lease with respect to the Phase
A-1 Parcel, to provide for a change in use of the Detention Area, modify Design
Standards and modify certain drainage easements, among other matters.  The
Ground Lease as modified by the First Supplement, Second Supplement and
Landlord's consent letter herein sometimes referred to as the "Lease."

    B.   The Commencement Date of the Term is August 15, 1995.

    C.   Landlord owns and operates the Airport, with the power to lease
premises and facilities and to grant rights and privileges with respect thereto.

    D.   Execution of this Amendment by Landlord is authorized by Ordinance
passed by the City Council of the City of Chicago on September 10, 1997 (C.J.P.,
pp. _________) ("Ordinance").

    E.   Tenant expects to pay certain of the costs of acquiring, constructing,
installing and equipping with the proceeds of the City of Chicago Variable/Fixed
Rate Demand Special Facilities Airport Revenue Bonds (CenterPoint O'Hare, L.L.C.
Project), Series 1997 (the "Bonds") described in the Ordinance, which require a
shorter term than the Term provided for 


<PAGE>

in the Lease.  Landlord and Tenant agree to shorten the Term, subject to an 
option to be granted to Tenant to extend the shortened term for a period not 
to exceed the original Term of the Lease in the aggregate, on the terms 
provided herein.

    F.   Capitalized terms used in this Amendment shall have the meanings set
forth in the Lease except as otherwise defined herein.


                           TERMS, COVENANTS, AND CONDITIONS

    NOW, THEREFORE, in consideration of the foregoing premises, and the terms,
covenants and conditions hereinafter set forth, Landlord and Tenant agree as
follows:

    1.   TERM.  

         (a)  Section 2.01 of the Lease is amended by amending and restating
    the last sentence, as follows:

              "The term of this Lease ("Term") shall commence on the
              commencement Date and terminate on August 1, 2042, (unless
              terminated sooner or extended as provided in this Lease) on the
              condition that Tenant shall pay Rent, comply with the terms,
              covenants and conditions, and yield possession, all as set forth
              in this Lease."

         (b)  The following provision is added to the Lease as a new Section
    2.06 to the Lease:

              "2.06     EXTENSION OPTION .  Subject to the provisions
              hereinafter set forth, Landlord hereby grants to Tenant an option
              to extend the Term of this Lease on the same terms, conditions
              and provisions as contained in this Lease, except as otherwise
              provided herein, for one period (the "Extension Period") after
              the stated expiration date of the Term, which Extension Period
              shall commence on August 2, 2042 (the "Extension Period
              Commencement Date") and end on the day before the sixtieth (60th)
              anniversary of the Commencement Date (being September 14, 2055)."

                   (A)  Said option shall be exercisable by written notice from
              Tenant to Landlord of Tenant's election to exercise said option
              given not later than the date which is twenty four (24) months
              prior to the Extension Period Commencement Date, time being of
              the essence.  If Tenant's option is not so exercised, said option
              shall thereupon expire.

                                       2
<PAGE>

                   (B)  Tenant may exercise said option, and an exercise
              thereof shall be effective, only if (1) at the time of Tenant's
              exercise of said option and on the Extension Period Commencement
              Date this Lease is in full force and effect and an Event of
              Default under Section 14.01(A) or (B) or other material Event of
              Default does not exist under this Lease, (2) an Event of Default
              in payment of principal or interest under the Bonds or other
              material Event of Default does not exist under the Loan Agreement
              or Indenture (as such terms are defined on Exhibit A), and (3)
              Tenant has received and furnished to Landlord a Favorable Opinion
              of Tax Counsel (as defined on Exhibit A hereto) and Tenant's
              determination of Bond-Financed Property Rent (as defined on
              Exhibit A hereto).

                   (C)  Rent during the Extension Period shall include the
              following:

                        (i)  Base Rent at the rate set forth in Sections 3.01
                             and 3.02 of the Lease;

                        (ii) Percentage Rent as provided in Section 3.03 of the
                             Lease; and 

                        (iii)     Bond-Financed Property Rent.

                   (D)  If Tenant has validly exercised said option, then
              within sixty (60) days after request by either party hereto,
              Landlord and Tenant shall enter into a written amendment to this
              Lease confirming the terms, conditions and provisions applicable
              to the Extension Period as determined in accordance herewith,
              with such revisions to the rental provisions of this lease as may
              be necessary to include the Bond Financed Property Rent.  As the
              Extension Period does not extend beyond the original Term of the
              Lease, no additional act by the City Council shall be required
              with respect to any such extension or amendment on the terms
              stated herein, the Commissioner having authority to execute or
              approve the confirmatory amendment and all documents in
              connection therewith.

    2.   APPLICATION OF CERTAIN DEFINITIONS UNDER LEASE.

         (a)  The financing transaction described in the Ordinance, including
    the issuance of the Bonds by the Landlord, the loaning of the proceeds
    thereof by the Landlord to the Tenant pursuant to the Loan Agreement and
    the incurrence by the Tenant, the Guarantor or any Affiliate thereof of any
    obligations currently set forth in the Loan Agreement to pay principal,
    purchase price, interest and premium owing with respect to the Bonds or
    under or in connection therewith either to the holders of the Bonds or as
    reimbursement to any national banking association, bank, trust company or

                                       3
<PAGE>

    other financial institution issuing a letter of credit or similar credit
    enhancement instrument to secure the Bonds, shall be collectively referred
    to herein as the "Bond Related Indebtedness."

         (b)  The Bond Related Indebtedness shall not be deemed to constitute a
    Sale under the Lease.

         (c)  A portion of the Bond Related Indebtedness not to exceed 
    seventy-five percent (75%) of the Costs of Construction shall be deemed to
    constitute "Construction Debt" and "Financing" for all purposes under the
    Lease, including, without limitation, for the purpose of applying the
    following defined terms in the Lease:  "Construction Debt," "Debt," "Free
    Cash Flow," "Gross Proceeds," "Net Financing Proceeds," "Net Rent," Net
    Residual Proceeds," "Net Sales Proceeds," and "Reinvested Funds."  The
    remainder of the Bond Related Indebtedness shall not be deemed to
    constitute "Debt," "Construction Debt" or "Financing" for any purpose under
    the Lease.  Statements required under Section 3.03(B) of the Lease shall
    also include computation of Debt Service (including its components) and
    Construction Debt used in any calculation of Percentage Rent.  No later
    than nineteen (19) months after Substantial Completion of Phase 3, Tenant
    shall furnish to Landlord the exact amount of the Construction Debt,
    together with such detail as will enable Landlord to verify its calculation
    as being an amount not to exceed seventy-five percent (75%) of the Costs of
    Construction.  Within nineteen (19) months after Substantial Completion of
    a Phase, Tenant shall furnish Landlord information on the allocation of
    actual Construction Costs to such Phase.  Within thirty (30) days after
    disbursement of the Bond proceeds, Tenant shall furnish Landlord the
    allocation of Costs of Construction for Phases which have previously been
    Substantially Completed and which are being reimbursed from the Bond
    proceeds.  Tenant shall retain information on Costs of Construction and
    their allocation between Phases for future use and furnish Landlord such
    information as may be required from time to time to calculate Percentage
    Rent throughout the Term.

         (d)  Tenant represents that the Bond Related Indebtedness to be
    incurred in connection with the initial issuance of the Bonds is not
    secured by a Leasehold Mortgage; provided, however, if at any time
    hereafter Tenant grants a Leasehold Mortgage in connection with the Bond
    Related Indebtedness, all provisions of the Lease relating to Leasehold
    Mortgages shall become applicable to the Bond Related Indebtedness from and
    after the date of such Leasehold Mortgage.

         (e)  With respect to certain definitions as applied to the portion of
    Bond Related Indebtedness deemed to constitute Construction Debt,

              (i)  the term "Costs of Construction" shall not include
                   those extraordinary costs of issuance of the
                   Bonds, as may be excluded by 

                                       4
<PAGE>

                   Landlord, which Landlord determines exceed, in
                   the aggregate, those costs which would reasonably
                   have been incurred in connection with more 
                   conventional Construction Debt secured by a 
                   Leasehold Mortgage; 

              (ii) for any Lease Year, the term "Net Rent" shall not
                   include interest earned during such Lease Year on
                   proceeds of the Bonds pending disbursement to pay
                   Costs of Construction, and the term "Debt Service"
                   shall not include any interest, principal or
                   letter of credit fees paid on Bonds allocable to
                   the undisbursed Bond proceeds during such Lease
                   Year;

             (iii) for any Lease Year, the term "Debt Service"
                   shall include payments of letter of credit
                   fees in connection with the Bonds during such
                   Lease Year, if any such payment is determined
                   to be an interest cost under Section 148 of
                   the Internal Revenue Code in calculating the
                   yield of the Bonds.

         (f)  The renewal, extension or replacement of the initial letter of
         credit securing the Bonds, or any renewal, extension or replacement
         thereof or any refunding or reissuance of the Bonds, including without
         limitation the execution and delivery by Tenant, Guarantor or any
         Affiliate of either of them of a reimbursement agreement or similar
         financing agreement with the issuer of such letter of credit or
         similar credit enhancement instrument securing the Bonds issued by the
         Landlord to finance the Project or any amendment, supplement or
         restatement of the Indenture, shall not be deemed to constitute a new
         "Financing" under the Lease if: (i) the outstanding principal amount
         of the Bonds is not increased in connection therewith, (ii) the Bonds
         remain outstanding under the Indenture, as amended, supplemented, or
         restated by Landlord, and (iii) interest on the Bonds is excludable
         from gross income of the holders thereof.

         (g)  The Landlord hereby acknowledges receipt of the Loan Agreement
    and the Indenture as the loan agreement described in Section 6.01(H) of the
    Lease without regard to the provisions of Article 12 and acknowledges that
    no assignment of the financing commitment is required by Landlord under
    Section 6.01(G) of the Lease.

                                       5
<PAGE>

         (h)  There shall be no double counting of the same payment of
    principal (i.e., deducting as both principal paid and Debt discharged) in
    calculating Net Cash Flow or Net Financing Proceeds.

    3.   BASE RENT AND COMMENCEMENT OF CONSTRUCTION.  The following changes are
made to Articles 3 and 6 of the Lease:

         (a)  The phrase "five (5) years" in Section 6.01(A)(4) is changed to
    "three (3) years."

         (b)  The phrase "twenty-four months" in the first sentence of 
    Section 6.01(I) is changed to "eighteen months."

         (c)  The phrase "forty-two (42) months" in Section 3.01(B)(3) is
    changed to "thirty-six (36) months."

    4.   LOAN AGREEMENT.  The Loan Agreement shall not be deemed to amend or
supersede the terms of the Lease.  If, in order to comply with its obligations
under Section 5.4 of the Loan Agreement, Tenant is obligated to take an action
at variance with the terms of the Lease, Tenant may not take such action unless
it either redeems the Bonds or first obtains Landlord's consent in writing to
such action.  Landlord may condition its consent on receiving indemnification
and security satisfactory to Landlord in its sole discretion.  A breach or
default by Landlord of its obligations under the Loan Agreement shall not be
deemed a breach or default of its obligations under the Lease. 

    5.   AMENDMENT.  Except as expressly modified herein, the provisions of the
Lease, including Article 21, remain unmodified and in full force and effect.

    6.   SHORT FORM OF LEASE.  Landlord and Tenant shall amend the Short Form
of Lease recorded on August 21, 1995 in the Recorder's Office of Cook County,
Illinois, as Document No. 95552388, as amended and recorded on May 13, 1996 in

amended and recorded on October 25, 1996, 1996, in the Recorder's Office of Cook
