ARTICLE ONE 

Definitions and Other Provisions of General Application 

Section 1.01.    Definitions 

All capitalized terms that are used herein and not otherwise defined herein shall have the meanings assigned to them in the Original Indenture.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having
a maturity comparable to the remaining term of the Notes to be redeemed (assuming for this purpose that the Notes matured on December 15, 2049) that would be used, at the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes. 
 “Comparable Treasury
Price” means with respect to any redemption date (1) the average of five Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if an
Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations. 

“Depositary” means The Depository Trust Company or its successor. 

“Independent Investment Banker” means J.P. Morgan Securities LLC, MUFG Securities Americas Inc., Scotia Capital (USA) Inc.,

Payment Date, provided, however, as long as the Notes are registered in the name of the Depositary, its nominee or a successor depositary, the Record Date shall be the close of business on the Business Day immediately preceding the Interest Payment

 “Reference Treasury
Dealer” means J.P. Morgan Securities LLC, MUFG Securities Americas Inc., Scotia Capital (USA) Inc., RBC Capital Markets, LLC, or Wells Fargo Securities, LLC, or each of their respective affiliates and successors; provided that if any such

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the
average, as determined by an Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to an Independent Investment Banker at 3:30
p.m., New York City time, on the third Business Day preceding such redemption date. 
 “Treasury Rate” means, as of any
redemption date, the rate per annum equal to the semiannual equivalent yield to maturity (computed as of the second Business Day immediately preceding that redemption date) of the Comparable Treasury Issue, assuming a price for the Comparable

Denominations; the Depositary 
 (a)    The initial principal amount of Notes that may be issued under this Fifteenth

Date, commencing on December 15, 2019. Such interest will be payable to the Holder thereof as of the related Record Date.

year of 360 days consisting of twelve 30-day months. Except for the effect of any adjustment in the Interest Payment Date as provided in the following sentence, the amount of interest payable for any
period shorter than a full six-month period for which interest is computed, will be computed on the basis of the actual number of days elapsed in such a 180-day period.
If any Interest Payment Date would otherwise be a day that is not a Business Day, the payment required to be made on such Interest Payment Date will be postponed to the next succeeding Business Day, and no interest will accrue on such payment for
the period from and after such Interest Payment Date to the date of such payment on the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding
Business Day, in each case with the same force and effect as if made on such Interest Payment Date.

Section 2.07.    Authentication and Delivery 

As provided in and pursuant to Section 303 of the Original Indenture, each time that the Company delivers Notes to the Trustee or
Authenticating Agent for authentication after the initial issuance of Notes under this Fifteenth Supplemental Indenture, the Company shall deliver a Supplemental Company Order in the form of Exhibit B to this Fifteenth
Supplemental Indenture (which form shall be completed upon delivery with the series designation applicable to the Notes) for the authentication and delivery of such Notes and the Trustee or such Authenticating Agent shall authenticate and deliver
such Notes. 
 Section 2.08.    Redemption; No Sinking Fund 

(a)    Prior to December 15, 2049, the Notes are subject to redemption, in whole or in part, at any time, at the
option of the Company, at a redemption price equal to the greater of: 
 (i)    100% of the principal
amount of Notes then outstanding to be redeemed, or 
 (ii)    the sum of the present values of the
remaining scheduled payments of principal and interest on the Notes then outstanding to be redeemed that would be due if such Notes matured on December 15, 2049 (not including any portion of such payments of interest accrued as of the
redemption date) discounted to the redemption date on a semiannual basis (computed based on a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus
twenty basis points (0.20%), as calculated by an Independent Investment Banker, 
 plus, in either of the above cases, accrued and unpaid interest thereon
to the redemption date. From and after December 15, 2049, the Notes are subject to redemption in whole or in part at the option of the Company at a redemption price equal to 100% of the principal amount of Notes then outstanding to be redeemed
plus accrued and unpaid interest thereon to the redemption date. 
 (b)    The Company will deliver a notice of
redemption at least 30 days but no more than 60 days before the redemption date to each Holder of Notes to be redeemed. If the Company elects to partially redeem the Notes, the Trustee will select in a fair and appropriate manner the Notes to be
redeemed (or, in the case of Notes held in global form, the Depositary will select the Notes to be redeemed in accordance with its standard procedures). 

  
 5 













 (c)    Unless the Company defaults in payment of the redemption price,
on and after the redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption.

that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on such Interest Payment Date. 

OPTIONAL REDEMPTION 

Prior to December 15, 2049, the Notes are subject to redemption, in whole or in part, at any time, at the option of the Company, at a
redemption price equal to the greater of: 
 (i)    100% of the principal amount of the Notes then
outstanding to be redeemed, or 
 (ii)    the sum of the present values of the remaining scheduled
payments of principal and interest on the Notes then outstanding to be redeemed that would be due if 

  
 A-5 













 
such Notes matured on December 15, 2049 (not including any portion of such payments of interest accrued as of the redemption date) discounted to the redemption date on a semiannual basis
(computed based on a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus twenty basis points (0.20%), as calculated by an Independent Investment
Banker, 
 plus, in either of the above cases, accrued and unpaid interest thereon to the redemption date. From and after December 15, 2049, the Notes
are subject to redemption in whole or in part at the option of the Company at a redemption price equal to 100% of the principal amount of Notes then outstanding to be redeemed plus accrued and unpaid interest thereon to the redemption date. 

The Company will deliver a notice of redemption at least 30 days but no more than 60 days before the redemption date to each Holder of the
Notes to be redeemed. If the Company elects to partially redeem the Notes, the Trustee will select in a fair and appropriate manner the Notes to be redeemed (or, in the case of Notes held in global form, the Depositary will select the Notes to be
redeemed in accordance with its standard procedures). 
 Unless the Company defaults in payment of the redemption price, on and after the
redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption. 
 The Notes are not entitled to the
benefit of any sinking fund or analogous provision.
