(5) as provided in Section 9.01(e) of the Base Indenture; or

In the case of clause (3)(A)(3) of this Section 1.3, in the event that any released Subsidiary Guarantor thereafter borrows money, incurs

Section 1.4 Additional Covenants. 

The following additional covenants shall apply with respect to the Offered Securities (except that Section 1.4(3) and related definitions
shall apply solely to the 2031 Securities), so long as any of the Offered Securities remain Outstanding (but subject to defeasance, as provided in Section 11.03 of the Base Indenture): 

(1) Limitation on Liens. 
 The
Parent will not, and will not permit any of its Subsidiaries to, create, incur, issue, assume or guarantee any debt secured by a Lien (other than Permitted Liens) upon any of its property or assets (other than Unrestricted Margin Stock), or any
shares of stock or evidences of indebtedness issued by any of its Subsidiaries and owned by the Parent or by any other of its Subsidiaries, owned on or after the Issue Date, without making effective provision to secure all of the Offered Securities,
equally and ratably with any and all other debt secured thereby, so long as any of such other debt shall be so secured. 
 (2) Limitation on
Sale and Leaseback Transactions. 

  
 13 

 The Parent will not, and will not permit any Subsidiary to, enter into any arrangement with
any person providing for the leasing by the Parent or any Subsidiary of any Property that has been or is to be sold or transferred by the Parent or such Subsidiary to such Person, with the intention of taking back a lease of such Property (a
“Sale and Leaseback Transaction”) unless either: 
 (a) within 12 months after the receipt of the proceeds
of the sale or transfer, the Parent or any Subsidiary apply an amount equal to the greater of the net proceeds of the sale or transfer or the fair value (as determined in good faith by the Parent’s Board of Directors) of such Property at the
time of such sale or transfer to the prepayment or retirement (other than any mandatory prepayment or retirement) of Senior Funded Debt; or 

(b) the Parent or such Subsidiary would be entitled, at the effective date of the sale or transfer, to incur debt secured by a
Lien on such Property in an amount at least equal to the Attributable Debt in respect of the Sale and Leaseback Transaction, without equally and ratably securing the Offered Securities pursuant to Section 1.4(1). 

The foregoing restriction in the paragraph above will not apply to any Sale and Leaseback Transaction (i) for a term of not more than
three years including renewals; (ii) between the Parent and a Subsidiary or between Subsidiaries; provided that the lessor is the Parent or a wholly owned Subsidiary; or (iii) entered into within 270 days after the later of the acquisition
or completion of construction of the subject Property. 
 (3) Special Mandatory Redemption. 

(a) If the Acquisition is not consummated, or the Acquisition Agreement is terminated, in each case, on or prior to
April 12, 2022 (each, a “Special Mandatory Redemption Event”), the Company will be required to redeem all of the 2031 Securities then outstanding on the Special Mandatory Redemption Date at the Special Mandatory Redemption
Price. Notice of a special mandatory redemption will be mailed (or otherwise delivered to Holders in accordance with the procedures of DTC) promptly after the occurrence of the Special Mandatory Redemption Event (and in any event no later than 2:00
p.m., New York City time, on the fifth business day immediately following such event) to the Trustee and each Holder of the 2031 Securities and will otherwise comply with Section 3.02 of the Base Indenture to the extent applicable;
provided that the notice periods set forth in Section 3.02 of the Base Indenture shall not apply. In the event that the Company has insufficient funds to redeem all of the 2031 Securities then outstanding on the Special Mandatory
Redemption Date, the Parent shall, on behalf of the Company, acquire, or cause to be acquired, all such 2031 Securities in accordance with this Section 1.4(3). 

(b) As used herein: 

“Special Mandatory Redemption Date” means the earlier to occur of (1) April 27, 2022 if the Acquisition has not
been consummated on or prior to 5:00 p.m., New York City time, on April 12, 2022; or (2) the 30th day (or if such day is not a business day, the first business day thereafter) following the termination of the Acquisition Agreement for any
reason. 
 “Special Mandatory Redemption Price” means 101% of the aggregate principal amount of the 2031 Securities then
Outstanding, plus accrued and unpaid interest to, but not including, the Special Mandatory Redemption Date.

Triggering Event. 

  
 14 

 (a) Upon the occurrence of a Change of Control Triggering Event, unless the
Company has exercised its right to redeem the Offered Securities pursuant to Section 1.1(6) hereof, the Company shall make an offer, for cash (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to
$150,000 or any integral multiples of $1,000 in excess thereof) of each Holder’s Offered Securities at a repurchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, on the Offered
Securities repurchased to, but not including, the date of repurchase, subject to the rights of Holders of Offered Securities on the relevant regular record date to receive interest due on the relevant Interest Payment Date (the “Change of
Control Payment”). 
 (b) Within 30 days following any Change of Control Triggering Event, or at the Company’s
option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company shall send a notice to Holders of the Offered Securities (in the case of Global Securities, electronically through the procedures
of the DTC), with a copy to the Trustee, describing the transaction or transactions that constitute the Change of Control Triggering Event, stating: 

(i) that the Change of Control Offer is being made pursuant to this Section 1.4(4) and that all Offered Securities
tendered will be accepted for payment; 
 (ii) the repurchase price and the repurchase date, which shall be no earlier than
30 days and no later than 60 days from the date such notice is sent (the “Change of Control Payment Date”);

(iv) that, unless the Company defaults in the payment of the Change of Control Payment, all Offered Securities accepted for
payment pursuant to the Change of Control Offer shall cease to accrue interest on and after the Change of Control Payment Date; 

(v) that Holders electing to have any Offered Securities repurchased pursuant to a Change of Control Offer shall be required to
surrender their Offered Securities, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Offered Security, or such other customary documents of surrender and transfer as the Company may reasonably
request, duly completed, to the paying agent as specified in the notice, or transfer their Offered Securities to the paying agent by book-entry transfer pursuant to the applicable procedures of the paying agent, prior to the close of business on the
third Business Day prior to the Change of Control Payment Date; 
 (vi) that Holders shall be entitled to withdraw their
election if the paying agent receives, no later than the close of business on the second Business Day preceding the Change of Control Payment Date, a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the
Offered Securities delivered for repurchase, and a statement that such Holder is withdrawing his election to have the Offered Securities repurchased; 

(vii) that Holders whose Offered Securities are being repurchased only in part will be issued new Offered Securities equal in
principal amount to the unpurchased portion of the Offered Securities surrendered, which unpurchased portion must be equal to $150,000 in principal amount or an integral multiple of $1,000 above that amount; and 

  
 15 

 (viii) if such notice is sent prior to the date of consummation of the
Change of Control, that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date. 

(c) The Company shall 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 Offered Securities 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 provisions of this Section 1.4(4), the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under
this Section 1.4(4) by virtue of such compliance. 
 (d) On the Change of Control Payment Date, the Company shall, to
the extent lawful, 
 (i) accept for payment all the Offered Securities or portions thereof properly tendered and not
withdrawn 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 the Offered Securities or portions of the Offered Securities accepted for payment; and 

(iii) deliver or cause to be delivered to the Trustee the Offered Securities properly accepted, together with an Officer’s
Certificate stating the aggregate principal amount of Offered Security or portions of Offered Securities being purchased by the Company. 

(e) The paying agent will promptly send to each Holder of Offered Securities accepted for payment the Change of Control Payment
for such Offered Securities deposited pursuant to Section 1.4(4)(d)(ii), and the Trustee will promptly authenticate and send (or cause to be transferred by book entry) to each Holder a new Offered Security equal in principal amount to any
unpurchased portion of the Offered Securities surrendered, if any; provided that each new Offered Security will be in a principal amount of $150,000 and or any integral multiple of $1,000. The Company will publicly announce the results of the Change
of Control Offer on or as soon as practicable after the Change of Control Payment Date. 
 (f) Notwithstanding anything
herein or in the Base Indenture to the contrary, the Company shall not be required to make a Change of Control Offer upon a Change of Control Triggering Event if (i) a third party makes the Change of Control Offer in the manner, at the times
and otherwise in compliance with the requirements set forth in this Section 1.4(4) and purchases all Offered Securities properly tendered and not withdrawn under the Change of Control Offer; or (ii) notice of redemption has been given
pursuant to Section 3.02 of the Base Indenture, unless and until there is a default in the payment of the applicable redemption price. 

Section 1.5 Additional Event of Default. 

(1) The following additional event shall be established and shall constitute an “Event of Default” under Section 6.01(a) of the
Base Indenture with respect to the 2031 Securities so long as any of the 2031 Securities remain Outstanding:
