Indenture). 
 Section 2.02 Maturity. The date upon which the Notes shall become due and payable at final maturity,
together with any accrued and unpaid interest, is March 1, 2019 (the “Maturity Date”). 
 Section 2.03
Form, Payment and Appointment. Except as provided in Section 2.04, the Notes shall be issued in fully registered, certificated form. Principal of and interest on the Notes will be payable, the transfer of such Notes will be
registrable, and such Notes will be exchangeable for Notes of a like aggregate principal amount, at the office or agency of the Company maintained for such purpose in Chicago, Illinois, which shall initially be the principal office of the Trustee;
provided, however, that payment of interest may be made at the option of the Company by check mailed to the Person entitled thereto at such address as shall appear in the Security register or by wire transfer to an account appropriately designated
by the Person entitled to payment; provided, that the paying agent shall have received written notice of such account 

  

 4 








 
designation at least five Business Days prior to the date of such payment (subject to surrender of the relevant Note in the case of a payment of interest on
a Redemption Date or the Maturity Date). 
 No service charge shall be made for any registration of transfer or exchange of the Notes, but
the Company may require payment from the holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. 
 The Security Registrar and Paying Agent for the Notes shall initially be the Trustee. 
 The Notes shall be
issuable in denominations of U.S. $2,000 and integral multiples of U.S. $1,000 in excess thereof. 
 The specified currency of the Notes
shall be U.S. Dollars. 
 Section 2.04 Global Notes. The Notes shall be issued initially in the form of a permanent Global
Security in registered form (a “Global Note”), deposited with The Depository Trust Company or such other Depositary as any officer of the Company may from time to time designate. Unless and until such Global Note is exchanged for
Notes in certificated form, such Global Note may be transferred, in whole but not in part, and any payments on the Notes shall be made only to the Depositary or a nominee of the Depositary, or to a successor Depositary selected or approved by the
Company or to a nominee of such successor Depositary. 
 Section 2.05 Interest. (a) Interest payable on any
Interest Payment Date, the Maturity Date or, if applicable, the Redemption Date, with respect to the Notes shall be the amount of interest accrued from, and including, the immediately preceding Interest Payment Date in respect of which interest has
been paid or duly provided for (or from and including the original issue date of March 5, 2009, if no interest has been paid or duly provided for with respect to the Notes) to, but excluding, such Interest Payment Date, Maturity Date or, if
applicable, Redemption Date, as the case may be (each, an “Interest Period”). 
 (b) The Notes will bear interest at
the rate of 5.40% per year from the original issue date thereof through and including the Maturity Date. Interest on the Notes shall be payable semi-annually in arrears on March 1 and September 1 of each year (each, an
“Interest Payment Date”), commencing September 1, 2009, to the Persons in whose names the relevant Notes are registered at the close of business on the Record Date for such Interest Payment Date, except as provided in
Section 2.05(d). 
 (c) The amount of interest payable for any full semi-annual Interest Period will be computed on the basis of
a 360-day year consisting of twelve 30-day months. The amount of interest payable for any period shorter than a full semi-annual Interest Period for which interest is computed will be computed on the basis of a 30-day month and, for any period less
than a month, on the basis of the actual number of days elapsed per 30-day month. In the event that any scheduled Interest Payment Date for the Notes falls on a day that is not a Business Day, then payment of interest payable on such Interest
Payment Date will be postponed to the next succeeding day which is a Business Day (and no interest on such payment will accrue for the period from and after such scheduled Interest Payment Date). 
 (d) In the event that the Maturity Date or a Redemption Date for any Note falls on a day that is not a Business Day, then the related payments of
principal, premium, if any, and interest may be made on the next succeeding day that is a Business Day (and no additional interest will accumulate on the amount payable for the period from and after the Maturity Date). Interest due on the Maturity
Date or a 

  

 5 








 
Redemption Date (in each case, whether or not an Interest Payment Date) of any Notes will be paid to the Person to whom principal of such Notes is payable.

 Section 2.06 No Sinking Fund. The Notes are not entitled to the benefit of any sinking fund. 
 ARTICLE 3 
 REDEMPTION OF THE NOTES 

Section 3.01 Optional Redemption by Company. Except as otherwise may be specified in this Supplemental Indenture, the Company shall
have the right to redeem the Notes, in whole or in part, at any time or from time to time, at its option, at a redemption price (the “Optional Redemption Price”) equal to the greater of: 
 (i) 100% of the principal amount of the Notes to be redeemed; or 
 (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date), discounted to the
Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 40 basis points, 
 plus in
each case accrued interest thereon to, but excluding, the Redemption Date. Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable
on the Interest Payment Date to the registered holders as of the close of business on the relevant Record Date. 
 The Company will mail
notice of such redemption to the registered holders of the Notes to be redeemed not less than 30 nor more than 60 days prior to the Redemption Date. If the Notes are only partially redeemed pursuant to this Section 3.01, the Notes to be
redeemed will be selected by the Trustee in such manner as in its sole discretion it shall deem appropriate and fair; provided, that if at the time of redemption the Notes to be redeemed are registered as a Global Note, the Depositary shall
determine, in accordance with its procedures, the principal amount of the Notes to be redeemed held by each of its participants that holds a position in such Notes. The Optional Redemption Price shall be paid prior to 12:00 noon, New York City time,
on the Redemption Date or at such later time as is then permitted by the rules of the Depositary for the Notes (if then registered as a Global Note); provided, that the Company shall deposit with the Trustee an amount sufficient to pay the
Optional Redemption Price by 10:00 a.m., New York City time, on the date such Optional Redemption Price is to be paid. 
 If money sufficient
to pay the redemption price of all of the Notes (or portions thereof) to be redeemed on the Redemption Date is deposited with the Trustee or paying agent on or before the Redemption Date and certain other conditions are satisfied, then on and after
such Redemption Date, interest will cease to accrue on such Notes (or such portion thereof) called for redemption. 
 Section 3.02
Change of Control Triggering Event. If a Change of Control Triggering Event occurs, unless the Company has exercised its right to redeem the Notes as described in Section 3.01, holders of Notes will have the right to require the
Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of their Notes pursuant to the offer described below (the “Change of Control Offer”) on the terms set forth in the Notes. In
the Change of Control Offer, the Company will be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase (the
“Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, or, at 

  

 6 








 
the Company’s option, prior to the date of the consummation of any Change of Control, but after public announcement of the transaction that constitutes
or may constitute the Change of Control, the Company will be required to mail a notice to holders of Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Triggering
Event and offering to repurchase the Notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”),
pursuant to the procedures required by the Notes and described in such notice. The notice shall, if mailed prior to the date of the consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control
Triggering Event occurring on or prior to the Change of Control Payment Date. The Company must comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and
regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering
Event provisions of the Notes, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 3.02 or the Change of Control Triggering Event provisions of
the Notes by virtue of such conflicts. 
 On the Change of Control Payment Date, the Company will be required, to the extent lawful, to:

 (i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 
 (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

 (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the
aggregate principal amount of Notes or portions of Notes being repurchased. 
 The Paying Agent will promptly mail to each holder of Notes properly tendered
the purchase price for the Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided
that each new Note will be in a principal amount of U.S. $2,000 or an integral multiple of U.S. $1,000 in excess thereof. The Company will not be required to make an offer to repurchase the Notes upon a Change of Control Triggering Event if a third
party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and such third party purchases all Notes properly tendered and not withdrawn under its offer. In addition, the
Company will not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a default in the payment of the Change of Control Payment upon a Change of
Control Triggering Event.

December 11, 2007 (herein called the “Base Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and, The Bank of New York Mellon Trust Company, N.A., as Trustee (herein called
the “Trustee”, which term includes any successor trustee under the Indenture), as amended and supplemented by the Supplemental Indenture, dated as of March 5, 2009 (herein called the “Supplemental Indenture”,
which term shall have the meaning assigned to it in such instrument, and together with the Base Indenture, herein called the Indenture) and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be authenticated and delivered. This Note is one of the series designated on the face hereof initially
limited in aggregate principal amount to $750,000,000. The Notes are unsecured general obligations of the Company. 
 The Company shall have
the right to redeem the Notes, in whole or in part, at any time or from time to time, at its option, at a redemption price (the “Optional Redemption Price”) equal to the greater of: 
 (i) 100% of the principal amount of the Notes to be redeemed; or 
 (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date), discounted to the
Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 40 basis points, 
 plus in
each case accrued interest thereon to, but excluding, the Redemption Date. Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable
on the Interest Payment Date to the registered holders as of the close of business on the relevant Record Date. 
 The Company will mail
notice of such redemption to the registered holders of the Notes to be redeemed not less than 30 nor more than 60 days prior to the Redemption Date. If Notes are only partially redeemed pursuant to Section 3.01 of the Supplemental Indenture,
the Notes to be redeemed will be selected by the Trustee in such manner as in its sole discretion it shall deem appropriate and fair; provided, that if at the time of redemption the Notes to be redeemed are registered as a Global Note, the
Depositary shall determine, in accordance with its procedures, the principal amount of the Notes to be redeemed held by each of its participants that holds a position in such Notes. The Optional Redemption Price shall be paid prior to 12:00 noon,
New York City time, on the Redemption Date or at such later time as is then permitted by the rules of the Depositary for the Notes (if then registered as a Global Note); provided, that the Company shall deposit with the Trustee an amount
sufficient to pay the Optional Redemption Price by 10:00 a.m., New York City time, on the date such Optional Redemption Price is to be paid. 
 If money sufficient to pay the redemption price of all of the Notes (or portions thereof) to be redeemed on the Redemption Date is deposited with the Trustee or Paying Agent on or before the Redemption Date and certain other conditions are
satisfied, then on and after such Redemption Date, interest will cease to accrue on such Notes (or such portion thereof) called for redemption. 
 In the event of redemption of this Note in part only, a new Note or Notes of this series for the unredeemed portion hereof shall be issued in the name of the holder hereof upon the cancellation hereof.

 Except as set forth in the preceding paragraphs and in Article 3 of the Supplemental Indenture, the
Company may not redeem the Notes of this series at its option prior to the Maturity Date. 
 If a Change of Control Triggering Event occurs,
unless the Company has exercised its right to redeem the Notes as described in Section 3.01 of the Supplemental Indenture, holders of Notes will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral
multiple of $1,000 in excess thereof) of their Notes pursuant to the offer described below (the “Change of Control Offer”) on the terms set forth in the Notes. In the Change of Control Offer, the Company will be required to offer
payment in cash equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase (the “Change of Control Payment”). Within 30 days
following any Change of Control Triggering Event, or, at the Company’s option, prior to the date of the consummation of any Change of Control, but after public announcement of the Change of Control, the Company will be required to mail a notice
to holders of the Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which
date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required by the Indenture and described in such notice. The notice
shall, if mailed prior to the date of the consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. The Company must
comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change
of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Triggering Event provisions of the Notes, the Company will comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations under the Change of Control Triggering Event provisions of the Notes by virtue of such conflicts. 
 On the Change of Control Payment Date, the Company will be required, to the extent lawful, to: 
 (i) accept
for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 
 (ii) deposit with the paying agent
an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and 
 (iii) deliver or
cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased. 
 The Paying Agent will promptly mail to each holder of Notes properly tendered the Change of Control Payment for the Notes, and the Trustee will promptly
authenticate and mail (or cause to be transferred by book-entry) to each holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided that each new Note will be in a principal amount of $2,000 or an
integral multiple of $1,000 in excess thereof. The Company will not be required to make an offer to repurchase the Notes upon a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in
compliance with the requirements for an offer made by the Company and such third party purchases all Notes properly tendered and not withdrawn under its offer. In addition, the Company will not repurchase any Notes if there has occurred and is
continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.
