Any such additional notes, together with the applicable series of Notes, will be consolidated with and constitute a single series of Debt Securities under the Original Indenture.

Section 4. Principal and Interest Payments; Maturity Date. (a) The 2028 Notes shall bear interest at the rate of 3.950% and the 2048 Notes shall bear interest at the rate of 4.400%, computed based on a 360-day year consisting of twelve 30-day months, from, and including, the date of issuance. Interest on the Notes will be payable semi-annually in arrears on May 1 and November 1 of each year, commencing November 1, 2018, to the Holders of the Notes as of the close of business on the immediately preceding April 15 and October 15, respectively. The principal amount of the 2028 Notes, together with all accrued and unpaid interest, shall be due and payable in full without further notice or demand on May 1, 2028, unless earlier redeemed, and the principal amount of the 2048 Notes, together with all accrued and unpaid interest, shall be due and payable in full without further notice or demand on May 1, 2048, unless earlier redeemed.

The Notes will be exchangeable and transfers of the Notes will be registrable, subject to the limitations provided in the Original Indenture, at the principal corporate trust office of the Trustee.

(c) If any interest payment date, stated maturity date or earlier redemption date falls on a day other than a Business Day, then the required payment of principal of and premium, if any, and interest may be made on the next succeeding Business Day, as if it were made on the date payment was due, and no interest will accrue on the amount so payable for the period from and after that interest payment date, the stated maturity date or earlier redemption date, as the case may be. The Notes will not have the benefit of a sinking fund.

Section 5. Optional Redemption. (a) At any time prior to February 1, 2028 with respect to the 2028 Notes (three months prior to the maturity date of the 2028 Notes) and November 1, 2047 with respect to the 2048 Notes (six months prior to the maturity date of the 2048 Notes), the Notes will be redeemable, in whole or in part, at any time or from time to time, at the option of the Company, at a redemption price equal to the greater of:

•

100% of the principal amount of the Notes to be redeemed; or

•

the sum of the present values of the Remaining Scheduled Payments on such Notes being redeemed that would be due if the Notes to be redeemed

matured on the applicable Par Call Date, discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (determined on the third Business Day preceding the redemption date),

plus, in each case, accrued and unpaid interest thereon, to, but excluding, the redemption date.

(b) On or after February 1, 2028 with respect to the 2028 Notes (three months prior to the maturity date of the 2028 Notes) and November 1, 2047 with respect to the 2048 Notes (six months prior to the maturity date of the 2048 Notes), the Notes will be redeemable, in whole or in part, at any time or from time to time, at the option of the Company, at 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon, to, but excluding, the redemption date.

(c) Notwithstanding the foregoing, installments of interest on the 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 Holders as of the close of business on the relevant record date.

(d) Notice of any redemption will be delivered at least 15 days but no more than 60 days before the redemption date to each Holder of the Notes to be redeemed. The notice of redemption for the Notes will state, among other things, the amount of Notes to be redeemed, the redemption date, the redemption price and the place or places that payment will be made upon presentation and surrender of Notes to be redeemed. If the Company redeems less than all of the Notes of a series, the Notes of that series to be redeemed shall be selected in accordance with the procedures of DTC. 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.

Section 6. Change of Control Offer to Purchase. (a) If a Change of Control Triggering Event occurs, Holders of the Notes may 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 at a purchase price of 101% of the principal amount, plus accrued and unpaid interest, if any, on such Notes, to, but excluding, the purchase date (unless a notice of redemption has been delivered within 30 days after such Change of Control Triggering Event stating that all of the Notes will be redeemed as described above). The Company shall be required to deliver to Holders of the Notes a notice describing the transaction or transactions constituting the Change of Control Triggering Event and offering to repurchase the Notes. The notice must be delivered within 30 days after any Change of Control Triggering Event, and the repurchase must occur no earlier than 30 days and no later than 60 days after the date the notice is delivered.

(b) On the date specified for repurchase of the Notes, the Company shall, to the extent lawful:

(i) accept for purchase all properly tendered Notes or portions of Notes;

(ii) deposit with the paying agent the required payment for all properly tendered Notes or portions of Notes; and

(iii) deliver to the Trustee the repurchased Notes, accompanied by an Officer’s Certificate stating, among other things, the aggregate principal amount of repurchased Notes.

(c) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations applicable to the repurchase of the Notes. To the extent that these requirements conflict with the provisions requiring repurchase of the Notes, the Company shall comply with such requirements instead of the repurchase provisions and shall not be considered to have breached its obligations with respect to repurchasing the Notes. Additionally, if an Event of Default exists under the Original Indenture (which is unrelated to the repurchase provisions of the Notes), including events of default arising with respect to other issues of debt securities, the Company shall not be required to repurchase the Notes notwithstanding these repurchase provisions.

(d) The Company shall not be required to comply with the obligations relating to repurchasing the Notes if a third party instead satisfies them.

So long as any of the Debt Securities remains outstanding, the Company will not, and the Company will not permit any Restricted Subsidiary to, create, assume, issue, guarantee or incur any Secured Indebtedness of the Company or any Restricted Subsidiary unless immediately thereafter the aggregate amount of all Secured Indebtedness (exclusive of certain types of permitted Secured Indebtedness described below), together with the discounted present value of all rentals (not otherwise excluded from the limitations contained in Section 8(b)) due in respect of Sale and Leaseback Transactions, would not exceed 10% of Consolidated Net Tangible Assets, where, for purposes of the calculation, the discounted present value of all rentals does not include rentals to which the covenant discussed in Section 8(b) does not apply; provided, however, the foregoing restrictions shall not apply to Secured Indebtedness secured by the
