“2024 Redemption Date”) at the Company’s option. If the 2024 Notes are redeemed at any time prior to the Par Call Date, the 2024 Notes will be redeemed at a redemption price equal to the greater of: 

(1) 100% of the principal amount of the 2024 Notes to be redeemed, and 

(2) the sum of the present values of the remaining scheduled payments of principal and interest on the 2024 Notes to be redeemed that would

of twelve 30-day months) at the Treasury Rate plus 25 basis points, 
 plus, in each of the cases (1) and
(2) above, accrued and unpaid interest on the 2024 Notes to be redeemed to, but not including, the applicable 2024 Redemption Date. 

If the 2024 Notes are redeemed at any time on or after the Par Call Date, the 2024 Notes will be redeemed at a redemption price equal to 100%
of the principal amount of the 2024 Notes to be redeemed, plus accrued and unpaid interest on the 2024 Notes being redeemed to, but not including, the applicable 2024 Redemption Date. 

  
 11 













 Any redemption pursuant to this Section 6.01(a) is subject to the right of holders of
record on the relevant record date to receive interest due on an interest payment date that is on or before the applicable 2024 Redemption Date. 

(b)    The 2029 Notes may be redeemed, in whole or in part, at any time (the date of such redemption, a
“2029 Redemption Date”) at the Company’s option. If the 2029 Notes are redeemed at any time prior to the Par Call Date, the 2029 Notes will be redeemed at a redemption price equal to the greater of: 

(1) 100% of the principal amount of the 2029 Notes to be redeemed, and 

(2) the sum of the present values of the remaining scheduled payments of principal and interest on the 2029 Notes to be redeemed that would
have been made if the 2029 Notes matured on the Par Call Date (exclusive of interest accrued to the redemption date) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting
of twelve 30-day months) at the Treasury Rate plus 30 basis points, 
 plus, in each of the cases (1) and
(2) above, accrued and unpaid interest on the 2029 Notes to be redeemed to, but not including, the applicable 2029 Redemption Date. 

If the 2029 Notes are redeemed at any time on or after the Par Call Date, the 2029 Notes will be redeemed at a redemption price equal to 100%
of the principal amount of the 2029 Notes to be redeemed, plus accrued and unpaid interest on the 2029 Notes being redeemed to, but not including, the applicable 2029 Redemption Date. 

Any redemption pursuant to this Section 6.01(b) is subject to the right of holders of record on the relevant record date to receive
interest due on an interest payment date that is on or before the applicable 2029 Redemption Date. 
 (c)    The
reference in the first sentence of Section 14.02 of the Base Indenture to “60 days” is hereby replaced with “45 days,” solely with respect to the Notes. 

(d)    Notice of any redemption of the Notes of each series shall be given in the manner and otherwise in accordance with
the provisions of Section 14.02 of the Base Indenture, as amended in Section 6.01(c). If the Company has given notice of redemption as provided in the Base Indenture, as amended in Section 6.01(c), and funds for the redemption of any
Notes of a series called for redemption have been made available on the redemption date referred to in that notice, such Notes will cease to bear interest on such redemption date. Any interest accrued to such redemption date will be paid as
specified in such notice. 
 (e)    Any redemption pursuant to this Article Six may, at the Company’s discretion,
be conditioned upon (1) the occurrence of a Change of Control or (2) the closing of another transaction, including a sale of securities or other financing, in each case as specified in the notice in reasonable detail. A notice of
conditional redemption will be of no effect unless all conditions to the redemption have occurred on or before the applicable redemption date or have been waived by the Company on or before the applicable redemption date. The Company will provide
notice to the holders of the Notes subject to the notice of conditional redemption of the 

  
 12 













 
satisfaction of all conditions as soon as practicable following occurrence of the conditions. The Company will provide notice to the holders of the Notes subject to the notice of conditional
redemption of any waiver of a condition or failure to meet such conditions no later than the applicable redemption date. 

(f)    If fewer than all of the Notes of a series are to be redeemed at any time, selection of Notes of such series for
redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on which such Notes are listed or, if such Notes are not listed on a national securities exchange, on a pro rata
basis, by lot, or such other method as the Trustee deems appropriate and fair (or such other method as DTC may require); provided, however, that the Notes of a series will be redeemed only in the minimum denominations of $2,000 and
integral multiples of $1,000 in excess thereof. 
 SECTION 6.02.    No Sinking Fund. The Notes are not
entitled to the benefit of any sinking fund. 
 SECTION 6.03.    Offer to Repurchase Upon a Change of Control
Triggering Event. 
 (a)    Upon the occurrence of a Change of Control Triggering Event, unless the Company has
otherwise exercised its right to redeem the Notes, each holder of Notes will have the right to require the Company to purchase all or a portion of such holder’s Notes pursuant to the offer described below (the “Change of Control
Offer”), at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to the date of purchase, subject to the rights of holders of Notes on the relevant record date to receive interest
due on the relevant interest payment date. 
 (b)    Within 30 days following the date upon which the Change of Control
Triggering Event occurred, unless the Company has otherwise exercised its right to redeem the Notes of a series, the Company will be required to deliver a notice to each holder of the unredeemed Notes, with a copy to the Trustee, which notice will
govern the terms of the Change of Control Offer; provided that, at the Company’s option, the Company may deliver such notice prior to any Change of Control but after the public announcement of the Change of Control. Such notice will
state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is sent, other than as may be required by law (the “Change of Control Payment Date”). The notice,
if sent prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. Holders of Notes
electing to have Notes purchased pursuant to a Change of Control Offer must surrender their Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address
specified in the notice, or transfer their Notes to the Paying Agent by book-entry transfer pursuant to the applicable procedures of DTC, before the close of business on the third Business Day prior to the Change of Control Payment Date. 

(c)    The Company will not be required to make a Change of Control Offer if a third party makes such an offer in the
manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and such third party purchases all Notes properly tendered and not withdrawn under its offer. 

  
 13 













 (d)    If holders of not less than 90% in aggregate principal amount of
the outstanding Notes of a series validly tender and do not withdraw the Notes of such series in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company, purchases all of such Notes of
such series validly tendered and not withdrawn by such holders, the Company will have the right, upon not less than 20 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control
Offer described above, to redeem all Notes of such series that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to the date of
redemption (subject to the right of holders of record on the relevant record date to receive interest on the relevant interest payment date). The provisions of Article Fourteen of the Base Indenture shall apply to any redemption pursuant to this
clause (d). 
 (e)    The Company will 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 such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Company will comply with those securities laws and regulations
and will not be deemed to have breached the Company’s obligations under the change of control offer provisions of the Notes by virtue of any such conflict. 

SECTION 6.04.    Payment If Date Fixed for Redemption or Repurchase Is Not a Business Day. If any date fixed
for redemption or repayment of any Notes pursuant to this Article Six is not a Business Day, the Company will make the required payment on the following Business Day with the same force and effect as if made on the date fixed for redemption or
repayment and, unless the Company defaults on the payment, no interest shall accrue for the period after such date.

 REVERSE OF NOTE 

This Note is one of the duly authorized issue of debt securities (hereinafter called the “Securities”) of the Company, of the series
specified on the face hereof, all issued or to be issued under and pursuant to the Indenture, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the rights and limitations of rights, obligations,
duties and immunities thereunder of the Trustee, and any agent of the Trustee, any Paying Agent, the Company and the holders of the Securities and the terms upon which the Securities are issued and are to be authenticated and delivered. To the
extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee to enter into supplemental indentures to the
Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of modifying in any manner the rights of the holders of the Securities of each series under the Indenture with
the consent of the holders of not less than a majority in principal amount of the Securities at the time outstanding of each series to be affected thereby on behalf of the holders of all Securities of such series. The Indenture also permits the
holders of a majority in principal amount of the Securities at the time outstanding of each series on behalf of the holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain
past defaults and their consequences with respect to such series under the Indenture. Any such consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders of this Note and of any Note
issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note or such other Note. 

Registrar and Paying Agent 
 The Company
shall maintain in the continental United States, an office or agency where Notes may be surrendered for registration of transfer or exchange and an office or agency where Notes may be presented for payment or for exchange. The Company has initially
appointed the Trustee, U.S. Bank National Association, as its Security registrar and Paying Agent. The Company reserves the right at any time to vary or terminate the appointment of any Paying Agent or Security registrar, to appoint additional or
other Paying Agents or other Security registrars and to approve any change in the office through which any Paying Agent or Security registrar acts. 

Optional Redemption of the Notes 
 The
Notes may be redeemed, in whole or in part, at any time (the “Redemption Date”) at the Company’s option. If the Notes are redeemed at any time prior to the Par Call Date, the Notes will be redeemed at a redemption price (the
“Redemption Price”) equal to the greater of: 
 (a)    100% of the principal amount of the Notes to be
redeemed, and 
 (b)    the sum of the present values of the remaining scheduled payments for principal and interest on
the Notes to be redeemed that would have been made if the Notes matured on the Par Call Date (exclusive of interest accrued to the applicable Redemption Date) discounted to the applicable Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points; 

plus, in each of the cases (a) and (b) above, accrued and unpaid interest on the Notes being redeemed to, but not including, the applicable Redemption
Date. 
 If the Notes are redeemed at any time on or after the Par Call Date, the Notes will be redeemed at a Redemption Price equal to 100%
of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on the Notes being redeemed to, but not including, the applicable Redemption Date. 

Notice of any redemption of the Notes shall be given in the manner and otherwise in accordance with the provisions of Section 14.02 of
the Base Indenture, as amended by Section 6.01(c) of the Fourth Supplemental Indenture. If the Company has given notice of redemption as provided in the Base Indenture, as amended by Section 6.01(c) of the Fourth Supplemental Indenture,
and funds for the redemption of any Notes called for redemption have 

  
 A-5 













 
been made available on the Redemption Date referred to in that notice, such Notes will cease to bear interest on such Redemption Date. Any interest accrued to the Redemption Date will be paid as
specified in such notice. 
 Change of Control Triggering Event 

Upon the occurrence of a Change of Control Triggering Event, the Company will be obligated to offer to repurchase this Note in the manner and
subject to the conditions provided in the Indenture. 
 Additional Issues 

The Company may from time to time, without notice to or the consent of the holders of the Notes, create and issue additional Notes. Any such
additional Notes will rank equally in right of payment with the Notes and will have the same interest rate, maturity date and other terms as the Notes herein provided for, except for the issue date, the public offering price, the payment of interest
accruing prior to the issue date or except for the first payment of interest following the issue date of such additional Notes. Any such additional Notes, together with the Notes herein provided for, will constitute a single series of
Securities under the Indenture. Any additional Notes may be issued by or pursuant to a supplement to the Indenture. 
 Transfer and Exchange 

The transfer of the Notes may be registered and Notes may be exchanged as provided in the Indenture. 

Sinking Fund 
 The Notes will not be
subject to any sinking fund. 
 Default 

If an Event of Default with respect to the Notes shall occur and be continuing, the principal of all the Notes may be declared due and payable
in the manner, with the effect and subject to the conditions provided in the Indenture. 
 Miscellaneous 

The registered holder of a Note may be treated as its owner for all purposes. 

Unless otherwise required by mandatory provisions of escheat or abandoned or unclaimed property laws, any moneys deposited with the Trustee or
any Paying Agent, or then held by the Company, for the payment of principal of, premium, if any, or interest on this Note that remains unclaimed for two years after the date upon which such payment shall have become due, shall be repaid to the
Company by the Trustee or by such Paying Agent on demand; or, if then held by the Company, shall be discharged from such trust. After that time, the holder of this Note shall, unless otherwise required by mandatory provisions of applicable escheat
or abandoned or unclaimed property laws, thereafter look only to the Company for any payment to which such holder may be entitled to collect. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of, and any premium and any interest on, this Note at the place, rate and respective times and in the coin or currency herein and in the Indenture prescribed. 

As provided in the Indenture and subject to the satisfaction of certain conditions therein set forth, including the deposit of certain trust
funds in trust, at the Company’s option, either the Company shall be deemed to have paid and discharged the entire indebtedness represented by, and the obligations under, the Notes and to have satisfied all the obligations (with certain

 REVERSE OF NOTE 

This Note is one of the duly authorized issue of debt securities (hereinafter called the “Securities”) of the Company, of the series
specified on the face hereof, all issued or to be issued under and pursuant to the Indenture, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the rights and limitations of rights, obligations,
duties and immunities thereunder of the Trustee, and any agent of the Trustee, any Paying Agent, the Company and the holders of the Securities and the terms upon which the Securities are issued and are to be authenticated and delivered. To the
extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. 

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee to enter into supplemental indentures to the
Indenture for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of modifying in any manner the rights of the holders of the Securities of each series under the Indenture with
the consent of the holders of not less than a majority in principal amount of the Securities at the time outstanding of each series to be affected thereby on behalf of the holders of all Securities of such series. The Indenture also permits the
holders of a majority in principal amount of the Securities at the time outstanding of each series on behalf of the holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain
past defaults and their consequences with respect to such series under the Indenture. Any such consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders of this Note and of any Note
issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note or such other Note. 

Registrar and Paying Agent 
 The Company
shall maintain in the continental United States, an office or agency where Notes may be surrendered for registration of transfer or exchange and an office or agency where Notes may be presented for payment or for exchange. The Company has initially
appointed the Trustee, U.S. Bank National Association, as its Security registrar and Paying Agent. The Company reserves the right at any time to vary or terminate the appointment of any Paying Agent or Security registrar, to appoint additional or
other Paying Agents or other Security registrars and to approve any change in the office through which any Paying Agent or Security registrar acts. 

Optional Redemption of the Notes 
 The
Notes may be redeemed, in whole or in part, at any time (the “Redemption Date”) at the Company’s option. If the Notes are redeemed at any time prior to the Par Call Date, the Notes will be redeemed at a redemption price (the
“Redemption Price”) equal to the greater of: 
 (a)    100% of the principal amount of the Notes to be
redeemed, and 
 (b)    the sum of the present values of the remaining scheduled payments for principal and interest on
the Notes to be redeemed that would have been made if the Notes matured on the Par Call Date (exclusive of interest accrued to the applicable Redemption Date) discounted to the applicable Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 30 basis points; 

plus, in each of the cases (a) and (b) above, accrued and unpaid interest on the Notes being redeemed to, but not including, the applicable Redemption
Date. 
 If the Notes are redeemed at any time on or after the Par Call Date, the Notes will be redeemed at a Redemption Price equal to 100%
of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on the Notes being redeemed to, but not including, the applicable Redemption Date. 

Notice of any redemption of the Notes shall be given in the manner and otherwise in accordance with the provisions of Section 14.02 of
the Base Indenture, as amended by Section 6.01(c) of the Fourth Supplemental Indenture. If the Company has given notice of redemption as provided in the Base Indenture, as amended by Section 6.01(c) of the Fourth Supplemental Indenture,
and funds for the redemption of any Notes called for redemption have 

  
 B-5 













 
been made available on the Redemption Date referred to in that notice, such Notes will cease to bear interest on such Redemption Date. Any interest accrued to the Redemption Date will be paid as
specified in such notice. 
 Change of Control Triggering Event 

Upon the occurrence of a Change of Control Triggering Event, the Company will be obligated to offer to repurchase this Note in the manner and
subject to the conditions provided in the Indenture. 
 Additional Issues 

The Company may from time to time, without notice to or the consent of the holders of the Notes, create and issue additional Notes. Any such
additional Notes will rank equally in right of payment with the Notes and will have the same interest rate, maturity date and other terms as the Notes herein provided for, except for the issue date, the public offering price, the payment of interest
accruing prior to the issue date or except for the first payment of interest following the issue date of such additional Notes. Any such additional Notes, together with the Notes herein provided for, will constitute a single series of
Securities under the Indenture. Any additional Notes may be issued by or pursuant to a supplement to the Indenture. 
 Transfer and Exchange

Sinking Fund

in the manner, with the effect and subject to the conditions provided in the Indenture. 
 Miscellaneous 

The registered holder of a Note may be treated as its owner for all purposes.

Company by the Trustee or by such Paying Agent on demand; or, if then held by the Company, shall be discharged from such trust. After that time, the holder of this Note shall, unless otherwise required by mandatory provisions of applicable escheat
or abandoned or unclaimed property laws, thereafter look only to the Company for any payment to which such holder may be entitled to collect.

which is absolute and unconditional, to pay the principal of, and any premium and any interest on, this Note at the place, rate and respective times and in the coin or currency herein and in the Indenture prescribed. 

As provided in the Indenture and subject to the satisfaction of certain conditions therein set forth, including the deposit of certain trust
funds in trust, at the Company’s option, either the Company shall be deemed to have paid and discharged the entire indebtedness represented by, and the obligations under, the Notes and to have satisfied all the obligations (with certain
exceptions) under the Indenture relating to the Notes or the Company shall cease to be under any obligation to comply with any term, provision or condition of certain restrictive covenants or provisions with respect to the Notes. 

The Notes are issuable in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof.

purposes; and neither the Company nor the Trustee nor any Paying Agent nor any Security registrar shall be affected by any notice to the contrary.
