 1 








 Upon the completion or cancellation of the Hamlet Tender Offer, beneficial interests in the Temporary
Global Notes shall be exchanged for beneficial interests in Permanent Global Notes. In order to effect such exchange, the Issuer shall provide written notice to the Trustee instructing the Trustee to (i) direct the Depositary to transfer the
specified amount of the outstanding beneficial interests in each Temporary Rule 144A Global Note and Temporary Regulation S Global Note to a corresponding Permanent Rule 144A Global Note or Permanent Regulation S Global Note, as applicable, and
provide the Depositary with all such information as is necessary for the Depositary to appropriately credit and debit the relevant holder accounts and (ii) provide prior written notice to all holders of such exchange, which notice must include
the date such exchange is proposed to occur, the CUSIP numbers of the relevant Temporary Global Notes and the CUSIP numbers of the relevant Permanent Global Notes into which such holders’ beneficial interests shall be exchanged. Upon such
exchange of beneficial interests pursuant to this Section 2.1(c), the Registrar shall reflect on its books and records the date of such transfer and a decrease and increase, respectively, in the principal amount of the applicable Temporary
Global Notes and Permanent Global Notes, respectively, equal to the principal amount of beneficial interests so transferred. Following any such transfer pursuant to this Section 2.1(c) of all of the beneficial interests in a Temporary Global
Note, such Temporary Global Note shall be canceled.” 
 (b) Section 2.2(a) of Appendix A to the Original Indenture is hereby
amended and restated in its entirety as follows:

transferred as a whole except as set forth in Section 2.1(b). Global Notes will not be exchanged by the Issuer for Definitive Notes except under the circumstances described in Section 2.1(b)(ii). Global Notes also may be exchanged or
replaced, in whole or in part, as provided in Sections 2.08 and 2.10 of this Indenture. Beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.2(b).” 
 (c) Section 2.2(a)(i) of Appendix A to the Original Indenture is hereby amended and restated in its entirety as follows: 
 “(i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Transfer Restricted Global Note may
be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Transfer Restricted Global Note in accordance with the transfer restrictions set forth in the Restricted Notes Legend; provided, however, that
(A) prior to the expiration of the Restricted Period, transfers of beneficial interests in a Regulation S Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person and (B) transfers of beneficial interests
in a Temporary Global Note may not be made to any person other than the offerors in the Hamlet Tender Offer. A beneficial interest in an Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial
interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.2(b)(i).”
