“The company may at any time and in its sole discretion determine that the Securities of any series or portion thereof issued in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event the Company will execute, and the Trustee, upon receipt of a Company Direction for the authentication and delivery of definitive Securities of such series in exchange for such Global Security or Securities, will authenticate and deliver Securities of such series in definitive form and in an aggregate principal amount equal to the principal amount of such Global Security or Securities being exchanged.

“Upon the exchange of a Global Security for Securities in definitive form, such Global Security shall be cancelled by the Trustee. Registered Securities issued in exchange for a Global Security pursuant to this Section shall be registered in such names and in such authorized denominations as the Depositary

-5-

for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the Trustee. The Trustee shall deliver such registered Securities to, or upon the order of, the persons in whose names such Securities are so registered.

“Unless otherwise specified by the Company pursuant to Section 2.01, a Global Security representing all or a portion of the Securities of a series may not be transferred except as a whole by the Depositary for such series to a nominee of such Depositary or by a nominee of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary.

“SECTION 2.14. Medium-Term Securities.

Notwithstanding any contrary provision herein, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Company Direction, Officers’ Certificate, supplemental indenture or Opinion of Counsel otherwise required pursuant to Sections 2.01, 2.03, 2.04, 2.07 and Section 14.05 at or prior to the time of authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued; provided that any subsequent direction by the Company to the Trustee to authenticate Securities of such series upon original issuance shall constitute a representation and warranty by the Company that as of the date of such direction, the statements made in the Officers’ Certificate or supplemental indenture delivered pursuant to Section 2.01 shall be true and correct as if made on such date.

-6-

“An Officers’ Certificate or supplemental indenture, delivered pursuant to his Section 2.14 in the circumstances set forth in the preceding paragraph, may provide that Securities which are the subject thereof will be authenticated and delivered by the Trustee on original issue from time to time upon the telephonic or written order of persons designated in such Officers’ Certificate or supplemental indenture (telephonic instructions to be promptly confirmed in writing by such person) and that such persons are authorized to determine, consistent with such Officers’ Certificate or any applicable supplemental indenture, such terms and conditions of the Securities as are specified in such Officers’ Certificate or supplemental indenture.”

C. Amendment of Article Three. Section 3.02 of the Indenture is amended as follows:

(2) The fourth paragraph is further amended to add, after the last sentence of such paragraph, the following sentence:

“If less than all the Securities of unlike tenor and terms of a series are to be redeemed, the particular Securities to be redeemed shall be selected by the Company.”

D. Amendment of Article Four. The last sentence of Section 4.01 of the Indenture is amended by adding at the end of such sentence the words “or by wire transfer to an account designated by such person.”

E. Amendment of Article Fourteen. Article Fourteen of the Indenture is amended as follows:

(1) Section 14.03 is amended to add the words “in Chicago, Illinois, New York City and such other cities as shall be specified with respect to such Securities” after the words “authorized newspaper” in the fourth sentence of that Section.

(2) Section 14.05 is amended by adding the words “Except as otherwise expressly provided in this Indenture” before the words “Upon any application or demand” in the first paragraph of such Section.

-7-

(3) Article Fourteen is further amended by renumbering Sections 14.07 through 14.09 as Sections 14.09 through 14.11, and by adding the following new Sections, to read as follows:

“SECTION 14.07. Moneys of Different Currencies To Be Segregated. The Trustee shall segregate money, funds and accounts held by the Trustee hereunder in one currency (or unit thereof) from any moneys, funds or accounts in any other currencies (or units thereof), notwithstanding any provision herein which would otherwise permit the Trustee to commingle such amounts.

“SECTION 14.08. Payment To Be in Proper Currency. Other than as provided herein or in the Security, an Officers’ Certificate or a supplemental indenture, the obligation of the Company to make any payment of principal of (and premium, if any) and interest, if any, on such Security shall not be discharged or satisfied by any tender by the Company, or collection by the Trustee, in any currency or currency unit other than that in which such Security is denominated (the “Specified Currency”), except to the extent that the Trustee timely holds for such payment the full amount of the Specified Currency when due and payable. If any such tender or collection is made in other than the Specified Currency, the Trustee may take such actions as it considers appropriate to exchange such other currency or currency unit for the Specified Currency. The costs and risks of any such exchange, including without limitation the risks of delay and exchange rate fluctuation, shall be borne by the Company, the Company shall remain fully liable for any shortfall or delinquency in the full amount of the Specified Currency then due and payable and in no circumstances shall the Trustee be liable therefor. The Company waives any defense of payment based upon any such tender or collection which is not in the Specified Currency, or which, when exchanged for the Specified Currency by the Trustee, is less than the full amount of the Specified Currency then due and payable.

Notwithstanding the foregoing, if a Specified Currency is not available to make any payment of principal of (and premium, if any) and interest, if any, on a Security denominated in other than Dollars due to the imposition of exchange controls or other circumstances beyond the Company’s control, the Company shall be entitled to satisfy its obligation by making such payment in Dollars on the basis of the Market Exchange Rate on the date of such payment, or if such Market Exchange Rate is not then available, on the basis of the most recently available Market Exchange Rate. For any Specified Currency, Market Exchange Rate shall mean the noon buying rate in New York, New York for cable transfers of such Specified Currency as certified for customs purposes by the Federal Reserve Bank of New York.
