(a) that the issuance ofthe O'Hare Airport Additional Senior Lien Bonds and the refunding ofthe Outstanding O'Hare Airport Obligations and any other bonds, notes or other

obligations issued by the City to finance or refinance any OTIare Airport Project will result in debt service savings or provide other benefits to O'Hare Airport;

that the O'Hare Airport Projects to be financed by the City with the proceeds ofthe O'Hare Airport Additional PFC Bonds are necessary and essential to the efficient operation of O'Hare Airport;
that the City's ability to issue the O'Hare Airport Additional Bonds from time to time without further action by this City Council, in various principal amounts and with various interest rates, maturities, redemption provisions and other terms will enhance the City's opportunities to obtain financing for O'Hare Airport;
that from time to time it is desirable to refund (i) outstanding O'Hare Airport revenue bonds and notes ofthe City (including bonds and notes payable from passenger facility charges or special facility revenues) and other payment obligations related thereto (the "O'Hare Airport Outstanding Obligations") and (ii) future issues of O'Hare Airport revenue bonds and notes of the City (including bonds and notes payable from passenger facility charges or special facility revenues) as may be outstanding from time to time, and other payment obligations related thereto (the "O'Hare Airport Future Outstanding Obligations"): and

Any notice of redemption mailed as provided in this Section 3.02 shall be conclusively presumed to have been given whether or not actually received by the addressee.
All notices of redemption shall state:
the Series designation of the Recovery Bonds to be redeemed,
the redemption date,

(b) With respect to an optional redemption of Recovery Bonds, such notice may state that said redemption is conditioned upon the receipt by the Trustee on or prior to the date fixed for redemption of moneys sufficient to pay the Redemption Price ofthe Recovery Bonds. If such moneys are not so received, such redemption notice shall be of no force and effect, the City shall not redeem such Recovery Bonds and such failure to deposit such funds shall not constitute an Event of Default under this Indenture. 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 Recovery Bonds will not be redeemed. Unless the notice of redemption shall be made conditional as provided above, on or prior to any redemption date for the Recovery Bonds, the City shall deposit with the Trustee an amount of money sufficient to pay the Redemption Price of all the Recovery Bonds or portions thereof which are to be redeemed on that date.


-18-

Notice of redemption having been given as aforesaid, the Recovery Bonds, or portions thereof, so to be redeemed shall, on the redemption date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the City defaults in the payment ofthe Redemption Price or unless, in the event of a conditional notice as described above, the necessary moneys were not deposited) such Recovery Bonds, or portions thereof, shall cease to bear interest. Upon surrender of such Recovery Bonds for redemption in accordance with said notice, such Recovery Bonds shall be paid by the Trustee at the Redemption Price.

If any Recovery Bond, or portion thereof, called for redemption shall not be so paid upon surrender thereof for redemption, the principal shall, until paid, bear interest from the redemption date at the rate borne by such Recovery Bond, or portion thereof, so called for redemption. All Recovery Bonds which have been redeemed shall be cancelled and destroyed by the Trustee and shall not be reissued.
Failure to give notice in the manner prescribed hereunder with respect to any Recovery Bond, or any defect in such notice, shall not affect the validity of the proceedings for redemption for any Recovery Bond with respect to which notice was properly given. Upon the happening ofthe above conditions and if sufficient moneys are on deposit with the Trustee on the applicable redemption date to redeem the Recovery Bonds to be redeemed and to pay interest due thereon and premium, if any, the Recovery Bonds thus called shall not, after the applicable redemption date, bear interest, be protected by this Indenture or the Bond Ordinance or be deemed to be Outstanding under the provisions of this Indenture.
If any Recovery Bond is transferred or exchanged on the Bond Register after notice has been given calling such Recovery Bond for redemption, the Trustee will attach a copy of such notice to the Recovery Bond issued in connection with such transfer or exchange.
If any Recovery Bond is not presented for payment when the principal amount thereof becomes due, either at maturity or at a date fixed for redemption thereof or otherwise, and if moneys sufficient to pay such Recovery Bond are held by the Trustee for the benefit of the Registered Owner of such Recovery Bond, the Trustee shall hold such moneys for the benefit of the Registered Owner of such Recovery Bond without liability to the Registered Owner for interest. The Registered Owner of such Recovery Bond thereafter shall be restricted exclusively to such funds for satisfaction ofany claims relating to such Recovery Bond.

If less than all the Recovery Bonds shall be called for redemption under any provision of this Indenture permitting such partial redemption, (i) such redemption shall be by lot in such manner as the Trustee may determine among such Recovery Bonds, and (ii) subject to other applicable provisions of this Indenture, the portion ofany Recovery Bond to be redeemed shall be in a principal amount equal to an Authorized Denomination. In selecting Recovery Bonds for redemption, the Trustee shall assign to each Recovery Bond of like Maturity Date and interest rate, a distinctive number for each


-19-

minimum Authorized Denomination of such Recovery Bond and shall select by lot from the numbers so assigned as many numbers as, at such minimum Authorized Denomination for each number, shall equal the principal amount of such Recovery Bonds to be redeemed. In such case, the Recovery Bonds to be redeemed shall be those to which were assigned numbers so selected; provided that only so much of the principal amount of each Recovery Bond shall be redeemed as shall equal such minimum Authorized Denomination for each number assigned to it and so selected. If it is determined that one or more, but not all, ofthe integral multiples ofthe Authorized Denomination of principal amount represented by any Recovery Bond is to be called for redemption, then, upon notice of intention to redeem such integral multiple of an Authorized Denomination, the Registered Owner of such Recovery Bond shall forthwith surrender such Recovery Bond to the Trustee for (a) payment to such Registered Owner of the Redemption Price ofthe integral multiple of the Authorized Denomination of principal amount called for redemption, and (b) delivery to such Registered Owner of a new Recovery Bond or Recovery Bonds in the aggregate principal amount ofthe unredeemed balance of the principal amount of such Recovery Bond. New Recovery Bonds representing the unredeemed balance of the principal amount of such Recovery Bond shall be issued to the Registered Owner thereof without charge therefor.

Proof of (i) the execution of any such instrument, or of an instrument appointing any such attorney, or (ii) the ownership by any person of the Recovery Bonds, shall be sufficient for any purpose of this Indenture (except as otherwise herein expressly provided) if made in the following manner, but the Trustee may nevertheless in its discretion require further or other proof in cases where it deems the same desirable:
The fact and date of the execution by any Owner or his attorney of such instrument may be proved by the certificate, which need not be acknowledged or verified, of an officer ofa bank or trust company satisfactory to the Trustee or ofany notary public or other officer authorized to take acknowledgments of deeds to be recorded in the jurisdiction in which he purports to act, that the person signing such request or other instrument acknowledged to him the execution thereof, or by an affidavit ofa witness of such execution, duly sworn to before such notary public or other officer.
The authority of the person or persons executing any such instrument on behalf of a corporate Owner of Recovery Bonds may be established without further proof if such instrument is signed by a person purporting to be the president or vice president of such corporation with a corporate seal affixed and attested by a person purporting to be its secretary or an assistant secretary.

(b) The ownership of Recovery Bonds and the amount, numbers and other identification, and date of ownership of the same shall be proved by the Bond Register. Any request, consent or vote of the Owner ofany Recovery Bond shall bind all future Owners of such Recovery Bond in respect of anything done or suffered to be done by the City or the Trustee in accordance therewith.

The Trustee shall file with the City proof of the mailing of such notice.

Recovery Bonds authenticated and delivered after the effective date of any action taken as in this Article provided may, and, if the Trustee so determines, shall, bear a notation by endorsement or otherwise in form approved by the City and the Trustee as to such action, and in that case upon demand of the Owner of any Recovery Bond Outstanding at such effective date and presentation of his Recovery Bond for that purpose at the Designated Corporate Trust Office of the Trustee or upon any exchange or registration of transfer of any Recovery Bond Outstanding at such effective date, suitable notation shall be made on such Recovery Bond or upon any Recovery Bond issued upon any such exchange or registration of transfer by the Trustee as to any such action.

In computing the amount in any Fund or Account, obligations maturing within the three year period next succeeding the date of computation shall be valued at amortized value, and obligations maturing more than three years following the date of computation shall be valued at the lower of amortized value or market value; provided that investment agreements described in clause (h) of the definition of "Qualified Investments" shall be valued at amortized value.
For purposes of this Senior Lien Indenture amortized value means par, if the obligation was purchased at par, or, when used with respect to an obligation purchased at a premium above or a discount below par, means the value as of any given time obtained by dividing the total premium or discount at which such obligation was purchased by the number of interest payments remaining on such obligation after such purchase and deducting the amount thus calculated for each interest payment date after such purchase from the purchase price in the case of an obligation purchased at a premium or adding the amount thus calculated for each interest payment date after such purchase to the purchase price in the case of an obligation purchased at a discount. Valuation shall be made on each June 15 and December 15, or if such day is not a business day of the Trustee then on the business day of the Trustee immediately preceding such June 15 or December 15, and at any other time required hereunder or under any Supplemental Indenture, and on any particular date shall not include the amount of interest then earned or accrued to such date on any deposit or investment.

744124332 4

Senior Lien Obligations for their consent thereto in form satisfactory to the Trustee, shall be mailed by the City to the owners ofthe Senior Lien Obligations (but failure to mail such copy and request shall not affect the validity of the Supplemental Indenture when consented to as in this Section provided).
